Algorithm predicts late liver disease ICU benefit
AT THE INTERNATIONAL LIVER CONGRESS 2016
BARCELONA – An algorithm that has been developed to help clinicians decide whether or not to refer a patient with end-stage liver disease (ESLD) with organ failure for intensive care treatment predicted mortality in the vast majority of cases, but came under fire during discussion as being potentially “quite dangerous” at the International Liver Congress.
When retrospectively applied to data on 465 patients with end-stage liver disease (ESLD), the algorithm correctly predicted 30-day mortality in 87% of cases.
Determining which patients with severe cirrhosis and acute-on-chronic liver failure (ACLF) should be transferred for intensive care is challenging, explained presenting study author Dr. Katrine Lindvig of Odense University Hospital in Denmark.
“More than 30 studies have looked at mortality in cirrhotic patients with organ failure, and we know that the mortality ranges from 35% to 89% between 15 centers,” Dr. Lindvig said at the meeting sponsored by the European Association for the Study of the Liver. But, she asked, what is an acceptable mortality rate? With limited health care resources was there a point of no return at which referral for intensive care became futile or perhaps unethical?
Dr. Lindvig and colleagues developed an algorithm to help decide if a patient with ESLD is a candidate or not for intensive care based on three scoring systems: the premorbid Child-Pugh Score, the Model of End stage Liver Disease (MELD) score, and the ACLF grade. Data were obtained from four centers in Belgium, Austria, and Denmark, which included two hepatology wards and two ICUs.
A green light for ICU referral was given to patients’ with premorbid Child-Pugh A or B, or a premorbid MELD score of less than 20. Patients with premorbid Child-Pugh C or higher MELD score could also be referred if they had an ACLF grade of 2 or less.
Conversely, patients with Child-Pugh C or a premorbid MELD score of 20 or higher and who had an ACLF grade of 3 or more were given a red light as they would be unlikely to benefit from ICU therapy. Special cases could be discussed, of course, such as those listed for liver transplantation.
Results showed that 394 would get the green light to be referred to ICU and 70 would get a red light, indicating that there would probably be no benefit. Of these 155 (39%) and 53 (75%) in each group, respectively, died within 30 days. Of the 17 patients who survived in the red light group, 12 were still alive at 6 months, and nine were still alive at 1 year.
Comparing the results with the ACLF, there were 35 (30%) of 114 patients with a score of three or higher that were still alive at 30 days and had been coded red by the algorithm. Dr. Lindvig noted, however, that the ACLF was purely descriptive and not developed as a predictive tool.
“However, when we combine the ACLF with the premorbid liver function the algorithm is significantly superior to the ACLF grade alone,” Dr. Lindvig said.
“We have no intention to replace good clinical judgment,” she added. “We simply want to assist the clinical decision making to make the decision more objective.” A computer-based program and app is now being developed in order to optimize and test the algorithm further.
“If the first duty of a physician is to do no harm, then we must continually review our decision-making tools and favor those that have the highest predictive value of treatment success and – importantly – treatment failure,” EASL spokesman Dr. Tom Hemming Karlsen of Oslo University Hospital Rikhospitalet said in a press release. “This study adds to our knowledge of existing, well-recognized scoring systems, and provides an interesting approach for review and wider discussion by the liver community.”
However, the dichotomous nature of the algorithm’s output was criticized during the discussion session by several concerned delegates who felt that it was oversimplified and potentially “quite dangerous” to be giving a green or red light for ICU referral. “There are lots of different variables to consider,” maintained one. Another argued that futility was “clearly not proven” in almost one-third of cases when compared with using the ACLF. Another said that the output should “not be a verdict.”
Nevertheless, others thought that while it was “provocative,” there were perhaps signs of “getting close” to a very good prediction tool.
In an interview, Dr. Lindvig defended the algorithm by reemphasizing that this was envisaged purely as a decision aid. “It is dichotomous, and we are just trying to aid the decision-making process,” she said, noting that this was particularly relevant perhaps for more junior doctors who may have to make a life-saving decision in the middle of the night.

Multiple Morphologically Distinct Cutaneous Granular Cell Tumors Occurring in a Single Patient
Case Report
A 27-year-old black man was admitted to the hospital with chills; night sweats; unintentional 25-lb weight loss; and multiple widespread, painful, progressively enlarging skin nodules of 3 months’ duration. The lesions had first developed on the back and later appeared on the face, trunk, arms, thighs, and genital region. He denied dysuria or urethral discharge. He had a remote history of adequately treated chlamydia infection but no other remarkable personal or family history.

Physical examination revealed a thin man with more than 20 lesions on the face, trunk, arms, thighs, and genital region ranging in size from 1 to 4 cm. Lesion morphologies varied greatly and included subcutaneous firm nodules with no epidermal change (Figure 1); dermatofibromalike nodules with overlying erythema and hyperpigmentation (Figure 2); condylomalike, verrucous, pink papulonodules (Figure 3); ulcerated angular plaques with rolled borders and palpable tumor extension deep (1–2 cm) to the subcutis (Figure 4); and a vegetative, eroded, exophytic tumor with palpable deep extension (Figure 4). A diffuse, erythematous, macular eruption also was noted on the trunk and bilateral arms and legs including the soles of both feet along with nontender cervical, axillary, and inguinal lymphadenopathy. The ocular, oral, and nasal mucosae were not affected.
The differential diagnosis for each lesion differed based on morphology. Infectious, inflammatory, and neoplastic processes were considered, including syphilis, dermatofibroma, dermatofibrosarcoma protuberans, metastatic disease, leukemia cutis, sarcoidosis, panniculitis, condyloma acuminatum, and vegetative herpes simplex virus infection (inguinal lesion).
Laboratory data revealed a reactive rapid plasma reagin with treponemal IgG titers of 1:64. Urine chlamydia RNA probe and lymphogranuloma venereum (LGV) serum antibodies also were positive. Human immunodeficiency virus screening was negative. Positron emission tomography–computerized tomography revealed enlarged and hypermetabolic lymphadenopathy above and below the diaphragm.
After therapy with intravenous penicillin G and oral doxycycline for concurrent secondary syphilis and LGV, the patient’s macular eruption and constitutional symptoms resolved within weeks of the initial presentation. His lymphadenopathy improved, his rapid plasma reagin titer decreased, and his chlamydia RNA became undetectable. However, the skin lesions remained unchanged.
Incisional biopsies of 4 clinically distinct skin lesions revealed well-delineated dermal proliferations of cells with eosinophilic granular cytoplasm and indistinct cell borders (Figure 5). Two specimens displayed marked epidermal hyperplasia (Figure 6).
No atypical mitotic figures were identified. Immunohistochemistry for S-100 protein was diffusely positive in the neoplastic cells. Immunohistochemistry for Treponema pallidum was negative.
No mycobacterial or fungal organisms were identified in acid-fast bacillus, periodic acid–Schiff, or Gomori methenamine-silver–stained sections. All 4 lesions had histopathologic findings characteristic of granular cell tumors (GCTs). A lesion in the left inguinal region (Figure 4 [medial lesion]), which initially was thought to be condyloma latum or a squamous cell carcinoma (SCC), also was later confirmed to be a GCT.
Repeat positron emission tomography–computerized tomography several weeks later confirmed resolution of the previously noted lymphadenopathy. Although 2 GCTs have not recurred after biopsy, the other 2, which the patient refused to have completely excised, continued to grow. Follow-up 2.5 years after hospitalization revealed persistence of the lesions with no remarkable morphological changes.

Comment
First described in 1854, GCTs are uncommon neoplasms of probable Schwann cell origin that can arise in almost any location of the body but most often appear on the skin and in the subcutaneous tissues and oral cavity.1,2 The commonly regarded rule of thirds describes its most favored locations: one-third on the tongue, one-third on the skin, and one-third in internal organs.3,4 Granular cell tumors occur with greater frequency in adults, females, and black individuals.1-5
Cutaneous GCTs usually present as solitary asymptomatic masses; however, multiple tumors have been noted in up to 25% of reported cases.4,6 In children, multiple cutaneous GCTs have been reported in the setting of neurofibromatosis type I as well as with other disorders.2,5,7-9
Cutaneous GCTs have been reported to range from sessile, pedunculated, or verrucous nodules to subcutaneous papules and nodules with no epidermal change. Our case not only illustrated the diverse clinical appearance of cutaneous GCTs but also demonstrated multiple morphologically distinct cutaneous GCTs occurring in a single patient. Of particular interest is our patient’s coexisting secondary syphilis and LGV infections, which can pose a diagnostic dilemma to the unsuspecting clinician. The manifold appearances of this patient’s GCTs resulted in a broad differential diagnosis. Syphilis (condyloma latum), condyloma acuminatum, LGV, metastatic disease, Kaposi sarcoma, lymphoma, dermatofibrosarcoma protuberans, leiomyoma, SCC, and deep fungal and atypical mycobacterial infection were all considerations. In 1981, Apisarnthanarax1 reviewed 88 cases of GCTs seen over a 15-year period and discovered that the preoperative clinical diagnoses were incorrect in all cases. Skin biopsy is necessary to diagnose GCT, and our patient’s case underscores the need for a thorough history, physical examination, and laboratory evaluation to rule out coexisting diseases.
Histopathology of cutaneous GCTs shows an unencapsulated dermal proliferation of large monotonous polygonal cells with blurred cell borders and fine, granular, eosinophilic cytoplasm arranged in irregular sheets and nests. Nuclei are small, uniform, round, centrally located, and rarely contain mitoses.3 The presence of mitotic activity on histopathology does not necessarily portend malignant biological behavior.5 Overlying pseudoepitheliomatous hyperplasia has been reported in as many as 85% of GCTs and may mimic SCC.10 The neoplastic cells stain positively with S-100 protein, neuron-specific enolase, and peripheral nerve myelin proteins.3,4 The cytoplasmic granules are positive on periodic acid–Schiff staining and diastase resistant and will sometimes stain for CD68.1 Electron microscopy shows degraded myelinated axons intracellularly.4
Malignancy is rare and reportedly occurs in 1% to 3% of cases.4,5 Consideration of both clinical behavior and histopathology is important in distinguishing benign from malignant lesions. According to published reports, in GCTs that were regarded as malignant, size tended to be greater than 4 cm, growth was rapid, and metastases to regional lymph nodes were observed.4,5 Histologically, nuclear pleomorphism and atypia, cell spindling, vesicular nuclei with prominent nucleoli, necrosis, and high mitotic activity favor malignancy.1,3
Treatment is complete surgical excision. Observation is acceptable if tumors are asymptomatic and do not impede function. Regression of some GCTs has been induced with use of intralesional corticosteroids.5 Spontaneous regression is rare. Prior reports have emphasized the importance of long-term follow-up in patients with multiple GCTs to monitor for development of systemic lesions.4

After therapy with intravenous penicillin G and oral doxycycline for concurrent secondary syphilis and LGV, the patient’s macular eruption and constitutional symptoms resolved within weeks of the initial presentation. His lymphadenopathy improved, his rapid plasma reagin titer decreased, and his chlamydia RNA became undetectable. However, the skin lesions remained unchanged.
Incisional biopsies of 4 clinically distinct skin lesions revealed well-delineated dermal proliferations of cells with eosinophilic granular cytoplasm and indistinct cell borders (Figure 5). Two specimens displayed marked epidermal hyperplasia (Figure 6).
No atypical mitotic figures were identified. Immunohistochemistry for S-100 protein was diffusely positive in the neoplastic cells. Immunohistochemistry for Treponema pallidum was negative.
No mycobacterial or fungal organisms were identified in acid-fast bacillus, periodic acid–Schiff, or Gomori methenamine-silver–stained sections. All 4 lesions had histopathologic findings characteristic of granular cell tumors (GCTs). A lesion in the left inguinal region (Figure 4 [medial lesion]), which initially was thought to be condyloma latum or a squamous cell carcinoma (SCC), also was later confirmed to be a GCT.
Repeat positron emission tomography–computerized tomography several weeks later confirmed resolution of the previously noted lymphadenopathy. Although 2 GCTs have not recurred after biopsy, the other 2, which the patient refused to have completely excised, continued to grow. Follow-up 2.5 years after hospitalization revealed persistence of the lesions with no remarkable morphological changes.

Comment
First described in 1854, GCTs are uncommon neoplasms of probable Schwann cell origin that can arise in almost any location of the body but most often appear on the skin and in the subcutaneous tissues and oral cavity.1,2 The commonly regarded rule of thirds describes its most favored locations: one-third on the tongue, one-third on the skin, and one-third in internal organs.3,4 Granular cell tumors occur with greater frequency in adults, females, and black individuals.1-5
Cutaneous GCTs usually present as solitary asymptomatic masses; however, multiple tumors have been noted in up to 25% of reported cases.4,6 In children, multiple cutaneous GCTs have been reported in the setting of neurofibromatosis type I as well as with other disorders.2,5,7-9
Cutaneous GCTs have been reported to range from sessile, pedunculated, or verrucous nodules to subcutaneous papules and nodules with no epidermal change. Our case not only illustrated the diverse clinical appearance of cutaneous GCTs but also demonstrated multiple morphologically distinct cutaneous GCTs occurring in a single patient. Of particular interest is our patient’s coexisting secondary syphilis and LGV infections, which can pose a diagnostic dilemma to the unsuspecting clinician. The manifold appearances of this patient’s GCTs resulted in a broad differential diagnosis. Syphilis (condyloma latum), condyloma acuminatum, LGV, metastatic disease, Kaposi sarcoma, lymphoma, dermatofibrosarcoma protuberans, leiomyoma, SCC, and deep fungal and atypical mycobacterial infection were all considerations. In 1981, Apisarnthanarax1 reviewed 88 cases of GCTs seen over a 15-year period and discovered that the preoperative clinical diagnoses were incorrect in all cases. Skin biopsy is necessary to diagnose GCT, and our patient’s case underscores the need for a thorough history, physical examination, and laboratory evaluation to rule out coexisting diseases.
Histopathology of cutaneous GCTs shows an unencapsulated dermal proliferation of large monotonous polygonal cells with blurred cell borders and fine, granular, eosinophilic cytoplasm arranged in irregular sheets and nests. Nuclei are small, uniform, round, centrally located, and rarely contain mitoses.3 The presence of mitotic activity on histopathology does not necessarily portend malignant biological behavior.5 Overlying pseudoepitheliomatous hyperplasia has been reported in as many as 85% of GCTs and may mimic SCC.10 The neoplastic cells stain positively with S-100 protein, neuron-specific enolase, and peripheral nerve myelin proteins.3,4 The cytoplasmic granules are positive on periodic acid–Schiff staining and diastase resistant and will sometimes stain for CD68.1 Electron microscopy shows degraded myelinated axons intracellularly.4
Malignancy is rare and reportedly occurs in 1% to 3% of cases.4,5 Consideration of both clinical behavior and histopathology is important in distinguishing benign from malignant lesions. According to published reports, in GCTs that were regarded as malignant, size tended to be greater than 4 cm, growth was rapid, and metastases to regional lymph nodes were observed.4,5 Histologically, nuclear pleomorphism and atypia, cell spindling, vesicular nuclei with prominent nucleoli, necrosis, and high mitotic activity favor malignancy.1,3
Treatment is complete surgical excision. Observation is acceptable if tumors are asymptomatic and do not impede function. Regression of some GCTs has been induced with use of intralesional corticosteroids.5 Spontaneous regression is rare. Prior reports have emphasized the importance of long-term follow-up in patients with multiple GCTs to monitor for development of systemic lesions.4

Practice Points
- Granular cell tumors (GCTs) typically present as solitary lesions; however, multiple lesions occur in approximately 25% of cases.
- Granular cell tumors have a variable clinical appearance and may mimic malignant neoplasms (eg, squamous cell carcinoma) as well as infectious diseases (eg, condyloma, syphilis).
- The histological features of GCTs are distinctive, including an unencapsulated dermal proliferation of monotonous polygonal cells with indistinct borders and fine, granular, eosinophilic cytoplasm arranged in irregular sheets and nests.
Low transformation rate in nodular lymphocyte–predominant Hodgkin lymphoma
Fewer than 8% of cases of nodular lymphocyte–predominant Hodgkin lymphoma (NLPHL) transformed to diffuse large B-cell lymphoma (DLBCL), based on a large prospective single-center study with long-term follow-up.
This rate was lower than the risk of transformation reported for transformed follicular lymphoma or chronic lymphocytic leukemia, according to Dr. Saad Kenderian and his associates at the Mayo Clinic, Rochester, Minn. Transformation was significantly associated with splenic involvement at presentation and with prior chemotherapy exposure, but did not worsen overall survival, they added.
“To our knowledge, this cohort represents the largest analysis to date of consecutive patients with NLPHL,” they said.
The study comprised 222 patients with newly diagnosed NLPHL who were treated at Mayo Clinic between 1970 and 2011. Median age at diagnosis was 40 years, and two-thirds of patients were men. The median follow-up period was 16 years (Blood 2016;12:1960-6. doi: 10.1182/blood-2015-08-665505).
During follow up, 17 cases (7.6%) transformed to DLBCL, for a transformation rate of 0.74 cases for every 100 patient-years, the investigators said. Median time to transformation was 35 months (range, 6-268 months). Predictors of transformation included any prior chemotherapy exposure (P = .04) and splenic involvement (P = .03). The rates of 40-year freedom from transformation were 87% when there was no splenic involvement and 21% when the spleen was involved, and were 87% if radiation therapy was used as a single modality compared with 77% in patients treated with prior chemotherapy or chemoradiation.
Five-year overall survival was 76% in patients with transformed disease, which was similar to overall survival among patients whose disease did not transform to DLBCL, the researchers noted.
Other studies of NLPHL have reported anywhere from a 2% to a 17% transformation rate, but those studies had smaller sample sizes, shorter follow-up periods, and less rigorous enrollment criteria and methods to confirm transformation, the investigators noted. “The finding of splenic involvement as a risk factor for transformation was reported by previous investigators. Interestingly, the association between exposure to prior chemotherapy and reduced freedom from transformation has not been reported in the past, but it has been observed in other low-grade lymphoma studies,” they added. “In contrast to follicular lymphoma, transformed NLPHL is not associated with an adverse impact on OS, suggesting a possibly different biology of transformation.”
The research was partially supported by Lymphoma SPORE and the Predolin Foundation. The investigators had no disclosures.
Kenderian et al. report a lower rate of transformation (7.6%) to diffuse large B-cell lymphoma for patients with nodular lymphocyte–predominant Hodgkin lymphoma compared with other series and found that transformation did not have a negative impact on overall survival. Reassuringly, even if transformation occurs, it is generally at a low rate. Also, these patients do well with additional treatment and do not have worse overall survival. At the MD Anderson Cancer Center, we have used a regimen based on R-CHOP and have not seen transformations. But only through large cooperative clinical trials can we determine whether R-CHOP or other more novel regimens are actually superior to ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) or rituximab (R)-ABVD for patients at high risk of transformation.

DAAs, HCV-positive livers could reduce transplant waiting list
BARCELONA – Using direct-acting antiviral therapy and livers from HCV-positive donors are separate approaches that could help reduce waiting lists and ensure that patients with HCV in most need get a liver transplant, according to data from two studies presented at the International Liver Congress.
In a retrospective European cohort study, 33% of HCV-positive patients with decompensated cirrhosis who were awaiting a transplant were no longer considered to be in urgent need and almost 20% could be removed from the list altogether 60 weeks after starting treatment with direct-acting antivirals (DAAs).
Dr. Luca Belli of Niguarda Hospital, Milan, who presented the findings at the meeting, cautioned that while the results were encouraging, it is not clear how long the clinical improvement will last. “It will be critical to assess the long-term risks of death, further redeterioration, and developments of hepatocellular carcinoma more specifically, as all these factors still need to be verified,” he said at the meeting, sponsored by the European Association for the Study of the Liver (EASL).
Meanwhile, data from a large analysis of all solid transplant recipients in the United States showed that using livers from HCV-positive donors in HCV-positive recipients was associated with long-term patient outcomes similar to outcomes of using livers from non–HCV-negative donors in HCV-positive recipients, with no difference in mortality or graft survival.
“Over the past 2 decades, the use of HCV-positive organs for liver transplantation has tripled in the United States,” said Maria Stepanova, Ph.D., a senior biostatistician for Inova Health System in Falls Church, Va., who presented her findings at the meeting.
“Despite this, the medium- to long-term outcomes of HCV-positive liver transplant recipients transplanted from HCV-positive donors were not affected by HCV-positivity of a donor,” added Dr. Stepanova, who also works at the Center for Outcomes Research in Liver Disease in Washington, D.C.
Dr. Zobair Younossi, chairman of the department of medicine at Inova Fairfax (Va.) Hospital, and coauthor of the study, said during a press briefing that this does not mean that livers from HCV-positive donor could be used in HCV-negative recipients. The reason for that is that it would be causing an acute infection regardless of whether or not antiviral treatment is available and “at this point the evidence is not there,” he said.
Dr. Laurent Castera of Hôpital Beaujon in Paris, and Dr. Tom Hemming Karlsen of Oslo University Hospital Rikshospitalet in Norway commented on the significance of these data in press releases issued by the EASL. Both experts, who were not involved in the studies, noted the findings could help take the strain off the liver transplant list in the future.
“Treating patients with direct-acting antiviral therapy could result in those with a more pressing need for a liver transplant receiving the donation they need, potentially reducing the number of deaths that occur on the waiting list,” Dr. Castera said.
“With the number of people waiting for a liver transplant expected to rise, the study results should give hope over the coming years for those on the waiting list,” Dr. Karlsen said. Referring to the U.S. study, he said the results “clearly demonstrate a greater opportunity for use of HCV-positive livers over the coming years due to their comparable outcomes with healthy livers.”
The European study presented by Dr. Belli involved 134 patients with HCV and decompensated cirrhosis but without hepatocellular carcinoma listed for liver transplant between February 2014 and February 2015 at 11 centers in Austria, Italy, and France. Of these patients, 103 had been treated with DAAs while on the transplant list; approximately half had been treated with a single DAA (sofosbuvir plus ribavirin for 24-48 weeks) and half with two DAAs (sofosbuvir with either daclatasvir or ledipasvir for 12-24 weeks).
The primary endpoint was the probability of being “inactivated” and then “delisted.” Inactivated meant that there was clinical improvement resulting in patients being put “on hold,” and “delisted” was defined as patients being taken off the transplant list after a variable period of inactivation.
The median age of patients in the study was 54 years and 68% were male. Just under 50% of patients had a low (less than 16) MELD score, around 37% had a MELD score of 16-20, and 13% had a MELD score of more than 20. Around 45% had Child-Pugh B and 55% had Child-Pugh C cirrhosis. Two-thirds had medically controlled and 26% had medically uncontrolled ascites, and 46% had medically controlled and 1% had medically uncontrolled hepatic encephalopathy.
Good virologic efficacy was seen with both single- and dual-agent DAA therapy, with rapid virologic responses of 61% and 67% and early virologic responses of 98% and 98%. Of the 52 patients given single-agent DAA treatment, 22 had a transplant and one patient had a posttransplant relapse. Of the remaining 30 patients on the transplant list, four relapsed. Nineteen of 51 patients given dual-DAA therapy were transplanted and there was one relapse, with no relapses in the 32 patients who remained on the transplant list.
After about 60 weeks of follow-up, one in three patients were “inactivated” and not considered in urgent need of a transplant, but inactivation occurred as early as 12 weeks after DAA therapy, Dr. Belli observed.
Inactivation was associated with a 3.3 decrease in MELD score, a 2-point reduction in Child-Turcotte-Pugh score, and a 0.5-g/dL increase in serum albumin after 24 weeks. There was also regression or improvement in ascites and hepatic encephalopathy in most patients. The median time of delisting was 48 weeks.
These results suggest that there could be a wider role for DAA therapy even in the sickest of HCV-positive patients who are urgently awaiting a liver transplant. Another approach to increase the number of people receiving a transplant is to use HCV-positive livers. The practice has been increasing over the years, but it is not known if the approach is safe and if the risks outweigh the benefits.
To investigate, Dr. Stepanova and associates obtained data from the Scientific Registry of Transplant Recipients (SRTR) on all liver transplants performed in the United States between 1995 and 2003 involving HCV-positive patients. A total of 37,317 records were found, of which 33,668 had data on the donors’ HCV status and on the recipients’ mortality status. Of these, 1,930 (5.7%) had received a liver from an HCV-positive donor. Dr. Stepanova noted that there had been an increase in the percentage of patients who had received an HCV-positive liver, from less than 3% in 1995 to more than 9% in 2013.
Compared with HCV-negative donors, HCV-positive donors were older, were more likely to have a history of drug abuse, and more likely to be non–heart beating at the time of procurement.
The HCV-positive liver recipients also tended to be older, to be of African-American ethnicity, and to have liver cancer but lower MELD scores than those who received an HCV-negative liver. “So these are patients that cannot wait for a long time so maybe elect to use an HCV-positive donor,” Dr. Younossi said.
Adjusted hazard ratios (aHR) showed no statistically significant difference in posttransplant survival or posttransplant graft loss between HCV-positive and HCV-negative livers; aHR were a respective 1.03 and 0.905, with tight 95% confidence intervals. However, a more recent year of transplant did appear to suggest a possible advantage of using an HCV-positive donor liver in an HCV-positive patient, with lower mortality (aHR = 0.978 per year, P less than .0001) and graft failure (aHR = 0.960 per year, P less than .0001) rates.
While the use of HCV-positive livers in HCV-positive recipients was felt to be “reasonably safe,” these findings “cannot be used in support of indiscriminate use of HCV-positive donors,” Dr. Stepanova observed. Further studies are needed to establish criteria on which to select donors that would provide patients with the best possible risk-to-benefit ratio, she said.
Further avenues for research would also be to see if HCV-positive livers could be given to HCV-negative patients and if genotype matters. It would also need to be seen if posttransplantation antiviral treatment would be necessary.
Dr. Belli has received research support from Gilead, AbbVie and BMS and acted as a consultant to Gilead. Dr. Stepanova did not have conflicts of interest to disclose. Dr. Younossi has acted as a consultant to BMS, AbbVie, Gilead, GlaxoSmithKline, and Intercept. Dr. Castera and Dr. Karlsen had no conflicts of interest to disclose.

Referring to the U.S. study, he said the results “clearly demonstrate a greater opportunity for use of HCV-positive livers over the coming years due to their comparable outcomes with healthy livers.”
The European study presented by Dr. Belli involved 134 patients with HCV and decompensated cirrhosis but without hepatocellular carcinoma listed for liver transplant between February 2014 and February 2015 at 11 centers in Austria, Italy, and France. Of these patients, 103 had been treated with DAAs while on the transplant list; approximately half had been treated with a single DAA (sofosbuvir plus ribavirin for 24-48 weeks) and half with two DAAs (sofosbuvir with either daclatasvir or ledipasvir for 12-24 weeks).
The primary endpoint was the probability of being “inactivated” and then “delisted.” Inactivated meant that there was clinical improvement resulting in patients being put “on hold,” and “delisted” was defined as patients being taken off the transplant list after a variable period of inactivation.
The median age of patients in the study was 54 years and 68% were male. Just under 50% of patients had a low (less than 16) MELD score, around 37% had a MELD score of 16-20, and 13% had a MELD score of more than 20. Around 45% had Child-Pugh B and 55% had Child-Pugh C cirrhosis. Two-thirds had medically controlled and 26% had medically uncontrolled ascites, and 46% had medically controlled and 1% had medically uncontrolled hepatic encephalopathy.
Good virologic efficacy was seen with both single- and dual-agent DAA therapy, with rapid virologic responses of 61% and 67% and early virologic responses of 98% and 98%. Of the 52 patients given single-agent DAA treatment, 22 had a transplant and one patient had a posttransplant relapse. Of the remaining 30 patients on the transplant list, four relapsed. Nineteen of 51 patients given dual-DAA therapy were transplanted and there was one relapse, with no relapses in the 32 patients who remained on the transplant list.
After about 60 weeks of follow-up, one in three patients were “inactivated” and not considered in urgent need of a transplant, but inactivation occurred as early as 12 weeks after DAA therapy, Dr. Belli observed.
Inactivation was associated with a 3.3 decrease in MELD score, a 2-point reduction in Child-Turcotte-Pugh score, and a 0.5-g/dL increase in serum albumin after 24 weeks. There was also regression or improvement in ascites and hepatic encephalopathy in most patients. The median time of delisting was 48 weeks.
These results suggest that there could be a wider role for DAA therapy even in the sickest of HCV-positive patients who are urgently awaiting a liver transplant. Another approach to increase the number of people receiving a transplant is to use HCV-positive livers. The practice has been increasing over the years, but it is not known if the approach is safe and if the risks outweigh the benefits.
To investigate, Dr. Stepanova and associates obtained data from the Scientific Registry of Transplant Recipients (SRTR) on all liver transplants performed in the United States between 1995 and 2003 involving HCV-positive patients. A total of 37,317 records were found, of which 33,668 had data on the donors’ HCV status and on the recipients’ mortality status. Of these, 1,930 (5.7%) had received a liver from an HCV-positive donor. Dr. Stepanova noted that there had been an increase in the percentage of patients who had received an HCV-positive liver, from less than 3% in 1995 to more than 9% in 2013.
Compared with HCV-negative donors, HCV-positive donors were older, were more likely to have a history of drug abuse, and more likely to be non–heart beating at the time of procurement.
The HCV-positive liver recipients also tended to be older, to be of African-American ethnicity, and to have liver cancer but lower MELD scores than those who received an HCV-negative liver. “So these are patients that cannot wait for a long time so maybe elect to use an HCV-positive donor,” Dr. Younossi said.
Adjusted hazard ratios (aHR) showed no statistically significant difference in posttransplant survival or posttransplant graft loss between HCV-positive and HCV-negative livers; aHR were a respective 1.03 and 0.905, with tight 95% confidence intervals. However, a more recent year of transplant did appear to suggest a possible advantage of using an HCV-positive donor liver in an HCV-positive patient, with lower mortality (aHR = 0.978 per year, P less than .0001) and graft failure (aHR = 0.960 per year, P less than .0001) rates.
While the use of HCV-positive livers in HCV-positive recipients was felt to be “reasonably safe,” these findings “cannot be used in support of indiscriminate use of HCV-positive donors,” Dr. Stepanova observed. Further studies are needed to establish criteria on which to select donors that would provide patients with the best possible risk-to-benefit ratio, she said.
Further avenues for research would also be to see if HCV-positive livers could be given to HCV-negative patients and if genotype matters. It would also need to be seen if posttransplantation antiviral treatment would be necessary.
Dr. Belli has received research support from Gilead, AbbVie and BMS and acted as a consultant to Gilead. Dr. Stepanova did not have conflicts of interest to disclose.

BARCELONA – Using direct-acting antiviral therapy and livers from HCV-positive donors are separate approaches that could help reduce waiting lists and ensure that patients with HCV in most need get a liver transplant, according to data from two studies presented at the International Liver Congress.
In a retrospective European cohort study, 33% of HCV-positive patients with decompensated cirrhosis who were awaiting a transplant were no longer considered to be in urgent need and almost 20% could be removed from the list altogether 60 weeks after starting treatment with direct-acting antivirals (DAAs).
Dr. Luca Belli of Niguarda Hospital, Milan, who presented the findings at the meeting, cautioned that while the results were encouraging, it is not clear how long the clinical improvement will last. “It will be critical to assess the long-term risks of death, further redeterioration, and developments of hepatocellular carcinoma more specifically, as all these factors still need to be verified,” he said at the meeting, sponsored by the European Association for the Study of the Liver (EASL).
Meanwhile, data from a large analysis of all solid transplant recipients in the United States showed that using livers from HCV-positive donors in HCV-positive recipients was associated with long-term patient outcomes similar to outcomes of using livers from non–HCV-negative donors in HCV-positive recipients, with no difference in mortality or graft survival.
“Over the past 2 decades, the use of HCV-positive organs for liver transplantation has tripled in the United States,” said Maria Stepanova, Ph.D., a senior biostatistician for Inova Health System in Falls Church, Va., who presented her findings at the meeting.
“Despite this, the medium- to long-term outcomes of HCV-positive liver transplant recipients transplanted from HCV-positive donors were not affected by HCV-positivity of a donor,” added Dr. Stepanova, who also works at the Center for Outcomes Research in Liver Disease in Washington, D.C.
Dr. Zobair Younossi, chairman of the department of medicine at Inova Fairfax (Va.) Hospital, and coauthor of the study, said during a press briefing that this does not mean that livers from HCV-positive donor could be used in HCV-negative recipients. The reason for that is that it would be causing an acute infection regardless of whether or not antiviral treatment is available and “at this point the evidence is not there,” he said.
Dr. Laurent Castera of Hôpital Beaujon in Paris, and Dr. Tom Hemming Karlsen of Oslo University Hospital Rikshospitalet in Norway commented on the significance of these data in press releases issued by the EASL. Both experts, who were not involved in the studies, noted the findings could help take the strain off the liver transplant list in the future.
“Treating patients with direct-acting antiviral therapy could result in those with a more pressing need for a liver transplant receiving the donation they need, potentially reducing the number of deaths that occur on the waiting list,” Dr. Castera said.

Doppler ultrasound headset performs well at spotting sports-related concussion
VANCOUVER – A new transcranial Doppler platform that analyzes subtle changes in the cerebral blood flow waveform performed well in detecting sports-related concussion in a cohort study of 238 Los Angeles high school athletes.
The investigational headset device was able to differentiate between those with and without a recent concussion 83% of the time, investigators reported at the annual meeting of the American Academy of Neurology. In contrast, traditional transcranial Doppler analysis detected a recent concussion only 50%-60% of the time.
“Over the last few years, there has been growing evidence that cerebral hemodynamics are altered following sports-related concussion,” senior author Robert Hamilton, Ph.D., cofounder and chief science officer of Neural Analytics in Los Angeles, commented in a session and interview.
Most studies in this area have used MRI or traditional transcranial Doppler analysis, he said. However, the former is costly, time consuming, and not portable, and the latter has not proven very accurate.
As traditional Doppler analysis disregards the majority of waveform data, Dr. Hamilton and his colleagues developed an advanced platform that uses machine learning to analyze the entire shape of the cerebral blood flow velocity waveform through quantitative cerebral hemodynamics.
They compared the advanced analysis with traditional analysis among 69 high school athletes in contact sports who had sustained a concussion an average of 6 days earlier and a control group of 169 unaffected age-matched high school athletes from contact and noncontact sports.
Both groups had bilateral monitoring of blood flow in the middle cerebral artery with transcranial Doppler while they followed a standard cerebrovascular reactivity protocol that included rest and breath holding.
Results showed that for differentiating between athletes who did and did not have concussion, the advanced analysis had an area under the receiver operating characteristic curve of 83%. (Sensitivity was 72%, specificity was 82%, and overall accuracy was 80%.)
In comparison, the area under the curve was substantially lower for the traditional analysis measures: It was 55% for mean velocity (100% sensitivity, 0% specificity, 76% accuracy), 52% for the pulsatility index (86% sensitivity, 23% specificity, 61% accuracy), and 60% for the cerebrovascular reactivity index (51% sensitivity, 68% specificity, 64% accuracy).
“Unfortunately, concussion diagnostics and management today are basically subjective,” Dr. Hamilton commented. The advanced analysis may therefore improve the situation by providing objective evidence of blood flow dysfunction after injury.
The new analysis platform “is easy to use and portable, and [testing] can be done very quickly, within 5 minutes,” he noted. “The nice thing is it can be done on the sideline, in the emergency room, or in a doctor’s office.”
The investigators will next use the advanced analysis to track recovery of blood flow regulation after sports-related concussion and will compare its performance with that of additional modalities, such as MRI, according to Dr. Hamilton. Furthermore, they are testing it in various other populations: adolescents, college athletes, and members of the military.
“Ultimately, blood flow dysfunction is also important in a wide variety of conditions, such as stroke and dementia,” he pointed out. “So those are conditions that we are looking at to study this year and moving forward in the future.”

Sexual Orientation and Cancer Risk
Young people in sexual minorities are at higher risk of cancer because they engage in risky behavior more often, say researchers from City University of New York, Harvard, Boston’s Children’s Hospital, and San Diego State University.
The researchers analyzed data from 9,958 participants in the national Growing Up Today Study (1999-2010). The study participants were the children of the women in the Nurses’ Health Study II; those women were invited in 1996 to enroll their 9- to 14-year-old children. Of the participants, 84.5% reported being “completely” heterosexual, 12.1% were “mostly” heterosexual, 1.8% were lesbian or gay, and 1.6% were bisexual.

The researchers measured responses about tobacco and alcohol, diet and physical activity, exposure to ultraviolet radiation, and sexually transmitted infections.
Compared with completely heterosexual women, lesbian, bisexual, and mostly heterosexual women more frequently engaged in multiple cancer-related risk behaviors. For instance, they were more likely to have smoked, to be overweight, and to have been physically inactive in the previous year. Bisexual and mostly heterosexual women were more likely to have had a sexually transmitted infection. Interestingly, heterosexual women were more likely to have used a tanning booth ≥ 10 times in the previous year.
Compared with heterosexual men, sexual-minority women were also more often engaged in risky behaviors. The differences between gay/bisexual men and heterosexual men were less marked, although gay men more often vomited to control their weight, compared with heterosexual men, and had a higher prevalence of STIs.
The literature, the researchers note, tends to focus on “ever or never” behavior. They were mindful, they say, that exposure to a potential carcinogen usually must occur over time, and that the likelihood of cancer increases with exposure, which is why they focused on assessing frequent engagement in each cancer-related risk behavior, long term. Their findings indicated that sexual minorities, relative to heterosexuals, are at risk for cancer through multiple risk behaviors—“concerning,” they add, because the “additive or synergistic effect of another cancer-related risk behavior may provoke or exacerbate a determinant of cancer: chronic inflammation.”

Young people in sexual minorities are at higher risk of cancer because they engage in risky behavior more often, say researchers from City University of New York, Harvard, Boston’s Children’s Hospital, and San Diego State University.
The researchers analyzed data from 9,958 participants in the national Growing Up Today Study (1999-2010). The study participants were the children of the women in the Nurses’ Health Study II; those women were invited in 1996 to enroll their 9- to 14-year-old children. Of the participants, 84.5% reported being “completely” heterosexual, 12.1% were “mostly” heterosexual, 1.8% were lesbian or gay, and 1.6% were bisexual.

The researchers measured responses about tobacco and alcohol, diet and physical activity, exposure to ultraviolet radiation, and sexually transmitted infections.

Opioid reform legislation passes House committee
The House Energy & Commerce Committee has passed a comprehensive package of bills designed to curb the nation’s opioid epidemic.
Eleven opioid-related bills passed the full committee by voice vote on April 27 and April 28. Key provisions of the legislation would:
• Create an interagency task force to review best practices for pain management and prescribing.
• Require annual updates of federal opioid-prescribing guidelines.
• Authorize grants to test coprescribing opioids with buprenorphine or naloxone.
• Limit the number of pills prescribed.
• Increase the number of patients that a qualified addiction treatment specialist could see annually.
• Require an FDA advisory committee to review any new opioid proposed without abuse-deterrent properties.
• Require a detailed assessment of currently available inpatient and outpatient treatment beds.
• Prohibit the sale dextromethorphan-containing products to minors.
The full Senate also has a package of opioid-related bills to consider. On March 17, the Senate Committee on Health, Education, Labor and Pensions moved similar legislation to the Senate floor, including bills that would increase addiction patient panels, require coprescribing, and mandate insurance coverage of addiction treatment as required by current mental health parity laws.
Earlier this year, in a near unanimous vote, the Senate passed the Comprehensive Addiction and Recovery Act, which calls for the creation of a federal pain management best practices interagency task force. No funding was attached to the legislation, however, and companion legislation remains in committee in the House.
Although the opioid bills had bipartisan support in the Energy & Commerce Committee, rancor may yet surface. During mark-up, three amendments were defeated mostly along party lines. The amendments would have increased the number of patients each qualified provider can treat with buprenorphine to a variety of levels – one amendment called for a maximum of 250 patients while others called for as many as 300 or 500. Supporters of the amendments said higher numbers would ensure treatment for many more patients while opponents expressed concern about sacrificing quality of care for quantity.
Another defeated amendment called for a $1 billion appropriation for increased opioid treatment, echoing President Obama’s call earlier this year. Opponents painted the proposal as “fiscally irresponsible.”
At press time, the House had not scheduled consideration on the opioid bills.

Training impacted performance of surgical quality measures
INDIAN WELLS, CALIF. – Surgeons with fellowship training in female pelvic medicine and reconstructive surgery were significantly more likely to perform proposed quality measures at the time of hysterectomy for pelvic organ prolapse, compared with those who lack such training, a single-center study showed.
“The Physician Quality Reporting System was instituted as part of recent health care reform, with the aim of improving the reporting of quality measures, with the overall goal of improving the quality of care provided to patients throughout all areas of medicine,” Dr. Emily Adams-Piper said at the annual scientific meeting of the Society of Gynecologic Surgeons. “While there are many types of quality measures, including outcome measures and patient satisfaction measures, process measures may be the most directly applicable for the practicing clinician, because they provide recommended actions during specific patient encounters that can guide practice.”
Dr. Adams-Piper, a resident physician in the division of urogynecology at the University of California, Irvine, and her associates set out to investigate the use of proposed quality measures at the time of hysterectomy for pelvic organ prolapse (POP) among women receiving care from Southern California Permanente Medical Group, a large HMO.
They wanted to know if training background affected the rate of performance of four different quality measures related to hysterectomy for POP: offering conservative treatment prior to the surgical treatment of POP, quantitative assessment of POP with either a Baden-Walker or a POP-Q exam, apical support procedure performed at the time of hysterectomy for prolapse, and performance of intraoperative cystoscopy.
Patients who underwent hysterectomy for POP in 2008 were eligible for the study. The researchers reviewed electronic medical records for clinical and demographic data and categorized surgeons by their level of training.
“They were considered fellowship trained if they had pursued additional formal subspecialty training in female pelvic medicine and reconstructive surgery,” Dr. Adams-Piper explained. “Surgeons were considered grandfathered if they subsequently took the FPMRS [Female Pelvic Medicine and Reconstructive Surgery] boards when they became available in 2013. Surgeons were considered generalist if they fit into neither of these two categories and completed a residency in ob.gyn.”
Chi-squared tests were used to compare demographics and performance of the proposed quality measures. Of the 662 hysterectomies performed in 2008, 328 were included in the final analysis. The mean patient age was 60 years, the mean parity was 2.9, and the mean body mass index was 27.9 kg/m2.
Overall performance of the four proposed quality measures was high, ranging from 82%-87%. More than half of quality assessments (58%) were performed with the POP-Q exam, while the majority of apical support procedures were uterosacral ligament vault suspensions (67%), followed by sacrocolpopexy (18%), McCall culdoplasty (12%), and sacrospinous ligament fixation (3%).
When categorized by training, fellowship-trained surgeons performed 133 hysterectomies, “grandfathered” surgeons performed 55, and generalist gynecologic surgeons performed 140. Fellowship-trained surgeons performed each of the four proposed quality measures more often than did grandfathered surgeons, who performed them more often than generalist gynecologic surgeons did.
Specifically, conservative treatment was offered by 94% of fellowship-trained surgeons, 87% of grandfathered surgeons, and 76% of generalist gynecologic surgeons (P = .0002). Qualitative preoperative assessment of POP was performed by 99% of fellowship-trained surgeons, 93% of grandfathered surgeons, and 73% of generalist gynecologic surgeons (three-way comparison reached statistical significance, with a P less than .0001).
Apical repair was performed by 96% of fellowship-trained surgeons, 82% of grandfathered surgeons, and 69% of generalist gynecologic surgeons (P less than .0001). Finally, cystoscopy was performed by 98% of fellowship-trained surgeons, 91% of grandfathered surgeons, and 72% of generalist gynecologic surgeons (P less than .0001).
When the researchers evaluated the cumulative performance of all measures in the same patient, fellowship-trained surgeons had the highest rates (89%, compared with 62% of grandfathered surgeons, and 39% of generalist gynecologic surgeons; P less than .0001).
“When we looked at the patient characteristics and their distribution across the surgeon training backgrounds, we found no significant differences in the age, BMI, gravidity, or parity of the subjects that underwent surgeries with the three groups,” Dr. Adams-Piper said.
She acknowledged certain limitations of the study, including the fact that it reflects clinical practice in a single health care delivery system, it relied on prior documentation, and it evaluated data from 2008.
“From this study we can conclude that perioperative practice patterns differ by surgeon training background,” she said. “However, in order for the proposed quality measures to be clinically meaningful, they must be correlated with patient-centered outcomes.”
Dr. Adams-Piper reported having no financial disclosures. The meeting was jointly sponsored by the American College of Surgeons.

Scans show high prevalence of TBI among symptomatic retired NFL players
VANCOUVER – Many retired National Football League (NFL) players seeking care for neurocognitive symptoms have MRI evidence of traumatic brain injury, according to the largest study of this issue among living players.
Data reported at the annual meeting of the American Academy of Neurology show that 43% of a cohort of 40 symptomatic NFL retirees had abnormal results on diffusion tensor MRI and 30% had evidence of traumatic axonal injury on conventional MRI.
The likelihood of abnormal diffusion tensor MRI results was correlated, albeit weakly, with the length of the player’s NFL career, but not with the number of concussions sustained.
“It appears that subconcussive hits – that is, the cumulative effects and longer playing careers – place retired alumni at risk for abnormal diffusion tensor MRI,” commented lead author Dr. Francis X. Conidi, director of the Florida Center for Headache & Sports Neurology in Palm Beach and team neurologist for the Florida Panthers of the National Hockey League.
“This could be a possible link to chronic traumatic encephalopathy, as consensus is you need to have repetitive head trauma,” he proposed. “Or this could be a separate entity whereby, in NFL players, the symptoms we are seeing are actually related to the traumatic brain injury itself and [in a subset] with some genetic predisposition, they will go on to have progressive neurological decline.”
Although the cohort was quite young, only 39 years old on average, some had likely played football since youth, and that has implications for prevention, Dr. Conidi added in an interview. “One thing we need to consider is limiting the amount of contact that these people receive on a cumulative basis, starting when they are young and starting in practice, because that’s where most of the contact occurs,” he recommended.
“It is important to note that diffusion tensor imaging is not a routine part of a brain MRI study,” session moderator Dr. José E. Cavazos, professor of neurology and assistant dean at the University of Texas Health Science Center in San Antonio, said in comments provided by email. “The significant correlation between duration of years played and abnormalities in diffusion tensor imaging is of concern given the popularity of the sport.”
“The next step is to replicate the findings, but more importantly, it is to find surrogate markers for early detection for these abnormalities, aiming to intervene (sideline) those players at greater risk for developing cognitive deficits or other impairments,” he added.
In the study, the retired players had a battery of neuropsychological and imaging examinations and tests over a period of 2 days. They were classified as having abnormal diffusion tensor MRI results if they had fractional anisotropy (FA) values at least 2.5 standard deviations below those of age-matched peers in a normative database for specific regions of interest in the brain.
The players ranged in age from 27 to 56 years. On average, they had played 7 years in the NFL and sustained eight concussions during that time. Most had retired in the past 5 years.
Results showed that, overall, 43% had abnormal diffusion tensor MRI results, Dr. Conidi reported. Prevalence, however, varied according to player position: It was highest for defensive linemen (64%) and wide receivers (60%); intermediate for running backs (43%), defensive backs (33%), and offensive linemen (29%); and lowest for quarterbacks (0%) and linebackers (0%).
The number of years played was significantly correlated with abnormal results (P = .049), but the number of concussions was not.
In other findings, sizable proportions of the players had significant abnormalities in attention and concentration (43%), executive function (54%), learning and memory (46%), spatial and perceptual function (24%), and language (5%).
“These guys have played these positions probably since they were young. This isn’t just NFL. We don’t make any claims that professional football caused this,” Dr. Conidi emphasized.
As for future research, the investigators plan to undertake PET scanning to assess clinical and laboratory evidence of Alzheimer’s disease, study sleep pathology, and look for tau protein (a marker for chronic traumatic encephalopathy) in cerebrospinal fluid. Additionally, they will assess treatment outcomes.
The study is not without limitations, Dr. Conidi acknowledged. “With every study that has ever been done on these guys, it is a skewed population: They are coming to us and they are looking to be evaluated,” he elaborated. “The other issue is we don’t have a normative comparison database for the neuropsychological testing.”
Dr. Conidi disclosed that he is a consultant for the NFL, NHL, USTA, PGA, and NCAA and that he receives research support from the Seeing Stars Foundation.

“The next step is to replicate the findings, but more importantly, it is to find surrogate markers for early detection for these abnormalities, aiming to intervene (sideline) those players at greater risk for developing cognitive deficits or other impairments,” he added.
In the study, the retired players had a battery of neuropsychological and imaging examinations and tests over a period of 2 days. They were classified as having abnormal diffusion tensor MRI results if they had fractional anisotropy (FA) values at least 2.5 standard deviations below those of age-matched peers in a normative database for specific regions of interest in the brain.
The players ranged in age from 27 to 56 years. On average, they had played 7 years in the NFL and sustained eight concussions during that time. Most had retired in the past 5 years.
Results showed that, overall, 43% had abnormal diffusion tensor MRI results, Dr. Conidi reported. Prevalence, however, varied according to player position: It was highest for defensive linemen (64%) and wide receivers (60%); intermediate for running backs (43%), defensive backs (33%), and offensive linemen (29%); and lowest for quarterbacks (0%) and linebackers (0%).
The number of years played was significantly correlated with abnormal results (P = .049), but the number of concussions was not.
In other findings, sizable proportions of the players had significant abnormalities in attention and concentration (43%), executive function (54%), learning and memory (46%), spatial and perceptual function (24%), and language (5%).
“These guys have played these positions probably since they were young. This isn’t just NFL. We don’t make any claims that professional football caused this,” Dr. Conidi emphasized.
As for future research, the investigators plan to undertake PET scanning to assess clinical and laboratory evidence of Alzheimer’s disease, study sleep pathology, and look for tau protein (a marker for chronic traumatic encephalopathy) in cerebrospinal fluid. Additionally, they will assess treatment outcomes.
The study is not without limitations, Dr. Conidi acknowledged. “With every study that has ever been done on these guys, it is a skewed population: They are coming to us and they are looking to be evaluated,” he elaborated. “The other issue is we don’t have a normative comparison database for the neuropsychological testing.”

VANCOUVER – Many retired National Football League (NFL) players seeking care for neurocognitive symptoms have MRI evidence of traumatic brain injury, according to the largest study of this issue among living players.
Data reported at the annual meeting of the American Academy of Neurology show that 43% of a cohort of 40 symptomatic NFL retirees had abnormal results on diffusion tensor MRI and 30% had evidence of traumatic axonal injury on conventional MRI.
The likelihood of abnormal diffusion tensor MRI results was correlated, albeit weakly, with the length of the player’s NFL career, but not with the number of concussions sustained.
“It appears that subconcussive hits – that is, the cumulative effects and longer playing careers – place retired alumni at risk for abnormal diffusion tensor MRI,” commented lead author Dr. Francis X. Conidi, director of the Florida Center for Headache & Sports Neurology in Palm Beach and team neurologist for the Florida Panthers of the National Hockey League.
“This could be a possible link to chronic traumatic encephalopathy, as consensus is you need to have repetitive head trauma,” he proposed. “Or this could be a separate entity whereby, in NFL players, the symptoms we are seeing are actually related to the traumatic brain injury itself and [in a subset] with some genetic predisposition, they will go on to have progressive neurological decline.”
Although the cohort was quite young, only 39 years old on average, some had likely played football since youth, and that has implications for prevention, Dr. Conidi added in an interview. “One thing we need to consider is limiting the amount of contact that these people receive on a cumulative basis, starting when they are young and starting in practice, because that’s where most of the contact occurs,” he recommended.
