Vascular loops are rare congenital optic nerve anomalies that originate from the arterial or venous circulation; 90% arise from the arterial circulation.¹ Vascular loops are usually asymptomatic unless an arterial or venous occlusion, hyphema, and vitreous or preretinal hemorrhage should arise.^1-8 This article describes a patient who presented with a vitreous hemorrhage secondary to a vascular loop.

Case Presentation

A 67-year-old white male presented to the eye clinic at the Providence VA Medical Center in Rhode Island after experiencing floaters and “snowflakes” in the left eye for 2 days. The patient reported having no photopsias, loss of vision, preceding eye/head trauma, or Valsalva maneuver. His medical history was significant for well-controlled type 2 diabetes mellitus (known duration of 5 years), hypertension, hyperlipidemia, coronary artery disease, and anemia. His medications included aspirin 81 mg, furosemide, clonidine, labetalol, valsartan, glipizide, and lantus injections.

The patient’s ocular history was significant for cataracts in both eyes. On examination, best-corrected visual acuity was 20/20 in each eye with intraocular pressures of 15 mm Hg in the right eye and 14 mm Hg in the left eye. Anterior segment examination was notable for 1+ nuclear sclerotic cataracts in both eyes with red blood cells visible in the anterior chamber in the left eye. 

No PVD, retinal break, or detachment was present in the left eye with scleral depression. No background diabetic retinopathy was present in either eye. 

The patient was diagnosed with a vitreous hemorrhage associated with a vascular loop in the left eye. 

Discussion

Salient features of this case include the prominent vascular loop at the disc extending anteriorly into the vitreous and an absence of features suggestive of one of the more common etiologies of vitreous hemorrhage, such as PVD, retinal tear/detachment, proliferative diabetic retinopathy (PDR), or retinal vein occlusion.

The incidence of venous loops is 1 in 9,000 with no associated systemic conditions.^2,3 Typically unilateral, vascular loops arise at the optic disc from the central retinal artery or vein.^1-4 An arterial loop is a separate entity from a hyaloid artery.² The authors were unable to definitively determine whether the loop in this patient was arterial or venous in origin due to blockage from the associated retinal hemorrhage on FA.

Valsalva maneuver, vitreous traction, trauma, and loop torsion in patients with vascular loops can lead to amaurosis fugax, PVD, and hemorrhagic complications, such as hyphema and vitreous and retinal hemorrhages.^1,3,6-8 In addition, retinal ischemia and thrombosis from the vascular loops can lead to retinal artery or vein occlusions.^1-8 Vitreous and retinal hemorrhages, such as in this patient, are often observed with complete resolution and visual acuity returning to baseline.^4,5 For recurrent or nonresolving vitreous hemorrhages, a vitrectomy can be performed.^3,6

Conclusion

Patients with vascular loops should be educated to seek eye care if experiencing new onset floaters or visual loss.

CHICAGO—Prior exposure to blinatumomab does not appear to affect the successful manufacture of KTE-C19 or its efficacy in patients with relapsed/refractory acute lymphoblastic leukemia (ALL), an investigator reported at the 2018 ASCO Annual Meeting.

The clinical benefit of KTE-C19, an anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, was preserved regardless of whether patients were exposed to blinatumomab, said Bijal D. Shah, MD, of Moffitt Cancer Center in Tampa, Florida.

High rates of complete response and undetectable minimal residual disease (MRD) were independent of exposure to blinatumomab, a CD19/CD3 bispecific T-cell engager.

“We feel the results of these data support KTE-C19 as an effective option for adults with refractory leukemia, regardless of prior exposure to CD19-directed therapy,” Dr Shah reported at the meeting (abstract 7006*).

The current standard of care for adults with relapsed/refractory ALL includes blinatumomab, raising the question of whether prior exposure to this CD19-directed treatment could influence the manufacture or efficacy of KTE-C19.

Sara Cooley, MD, of Masonic Medical Center, University of Minnesota in Minneapolis, said results of this analysis suggest prior blinatumomab should not be a contraindication or concern in the context of KTE-C19.

“This remains to be shown with other CAR T-cell therapies,” she said in a presentation at ASCO on cellular therapy in leukemia.

The analysis by Dr Shah and co-investigators was based on ZUMA-3 (NCT02614066), a phase 1 study including adults with relapsed/refractory ALL who received KTE-C19 at doses of 0.5, 1, or 2 x 10⁶ cells/kg.

They excluded patients in the highest dose cohort, who were required to be blinatumomab naïve, per protocol. That left 23 patients who received 0.5 or 1 x 10⁶ cells/kg, of whom 11 had prior blinatumomab exposure and 12 did not.

Best overall response appeared to be independent of prior blinatumomab treatment, with a CR rate of 72% overall, and 63% and 80% for blinatumomab-exposed and blinatumomab-naïve patients, respectively.

The rate of undetectable MRD was likewise high at 88% in the prior blinatumomab group and 100% in the no-blinatumomab group.

Product characteristics did not vary according to blinatumomab exposure, though there was a trend toward a more differentiated phenotype in those patients who had received prior CD19-directed treatment, he said.

There were no significant differences between groups in the rate of grade 3 or greater cytokine release syndrome. Neurologic events were higher in the blinatumomab-naïve patients, though a higher percentage of those patients received the 1 x 10⁶ cells/kg dose, Dr Shah reported.

Investigators also looked at CAR T levels by treatment.

“We cannot appreciate any significant differences between the blinatumomab-naïve and the blinatumomab-exposed groups,” Dr Shah told ASCO attendees.

The ZUMA-3 trial was sponsored by Kite, a Gilead Company.

Twelve weeks of treatment with three different antipsychotics commonly used in children and adolescents with disruptive behavioral disorders was associated with rapid-onset adverse changes in adiposity and insulin sensitivity, results of a randomized clinical trial show.

The adverse effect on adiposity was greatest for children aged 6-18 years who received olanzapine, but was also seen in study participants randomized to receive risperidone or aripiprazole, according to results of the study published in JAMA Psychiatry.

These findings inform the risk-benefit analysis for off-label pediatric use of antipsychotics for disruptive behavior disorders, Ginger E. Nicol, MD, of Washington University, St. Louis, and colleagues wrote.

“The potential psychiatric benefits of antipsychotic use in this population, evident in this trial and others, should be carefully weighed against the potential for childhood onset of abdominal obesity and insulin resistance that – compared with adult onset – further increases long-term risk for [type 2 diabetes], cardiovascular disease, and related conditions,” the researchers wrote.

This randomized, prospective clinical trial included 144 antipsychotic-naive children and adolescents aged 6-18 years who had been diagnosed with one or more psychiatric disorders and clinically significant aggression. They were randomly and evenly assigned to 12 weeks of treatment with oral olanzapine, risperidone, or aripiprazole.

Those who received olanzapine had a 4.12% increase in percentage total body fat from baseline to week 12, as measured by dual-energy x-ray absorptiometry (DXA). That increase was significantly greater than the total body fat increases of 1.18% for risperidone and 1.66% for aripiprazole seen over that same time period (P less than .001 for time-by-treatment interaction), the researchers reported.

Insulin sensitivity decreased over time in the pooled study sample, with significant changes reported in insulin-stimulated glucose rate of disappearance, glucose rate of appearance, and glycerol rate of appearance. The changes did not differ significantly across the three treatment groups.

The lack of a placebo group in this study makes it unclear how much of the body fat and insulin sensitivity changes were attributable to antipsychotic medication. Psychiatric symptoms did improve significantly with treatment, the researchers noted.

Dr. Nicol reported research funding from the National Institute of Mental Health, Otsuka America Pharmaceutical, Alkermes PLC, The Sidney R. Baer Jr. Foundation, and the Center for Brain Research in Mood Disorders at Washington University in St Louis. Co-authors reported financial ties to Reviva Pharmaceuticals, Sunovion Pharmaceuticals, Indivior, Amgen, and other companies.

Illicit online sales of opioids increased significantly following a 2014 regulatory decision that restricted the legal supply of opioids in the United States, results of a recent analysis show.

Opioid sales in the so-called cryptomarkets also shifted toward more potent drugs, including fentanyl, after the U.S. Drug Enforcement Administration rescheduled hydrocodone combination products, making them harder to access, authors of the analysis reported.

Those results suggest “the possibility of a causal relation” between the schedule change and sales trends on cryptomarket sites, according to James Martin, PhD, of Swinburne University, Melbourne, Australia, and co-authors.

Researchers conducting a cost-utility analysis of sentinel lymph node (SLN) mapping and lymph node dissection (LND), both selective and routine, for low-risk endometrial carcinoma (clinical stage 1 disease with grade 1-2 endometrioid histology on preoperative endometrial biopsy), found that the SLN mapping had the lowest costs and the highest quality-adjusted survival of the three strategies.

Between the two strategies of LND, selective LND based on intraoperative frozen section was more cost-effective than routine LND.

The researchers created a model using data from past studies and clinical estimates. “Our biggest assumption was that sentinel lymph node mapping is associated with a decreased risk of lymphedema compared with lymph node dissection ... [from] several studies showing that having less than five lymph nodes excised was associated with a much smaller risk of developing lymphedema,” wrote Rudy S. Suidan, MD, of the MD Anderson Cancer Center, Houston, and his coauthors. Lymphedema was the main factor affecting quality of life in the analysis.

The analysis included estimates of rates of lymphadenectomy, bilateral mapping, and unilateral mapping, 3-year disease-specific survival, and overall survival, all of which were compared with third-party reimbursement costs at 2016 Medicare rates.

SLN mapping cost $16,401 per patient, while selective LND cost $17,036 per patient and routine LND cost $18,041 per patient. These strategies had quality-adjusted life years of 2.87, 2.81, and 2.79, respectively.

The superior cost-effectiveness of SLN mapping held, even when the researchers altered several of the variables in the model, including assuming open surgery instead of minimally invasive, and altering the assumed risk of lymphedema.

In addition to the possible limitation of making assumptions about SLN mapping and lymphedema, the researchers also pointed to the 3-year survival rates as shorter-term than preferable, driven by the available literature. The quality-adjusted life years did not differ much between the strategies because “most patients with low-risk cancer tend to have good clinical outcomes,” they wrote.

“This adds to the body of literature evaluating the clinical benefits of this strategy and may help health care providers in the decision-making process as they consider which approach to use,” the researchers wrote.

The researchers created a model using data from past studies and clinical estimates. “Our biggest assumption was that sentinel lymph node mapping is associated with a decreased risk of lymphedema compared with lymph node dissection ... [from] several studies showing that having less than five lymph nodes excised was associated with a much smaller risk of developing lymphedema,” wrote Rudy S. Suidan, MD, of the MD Anderson Cancer Center, Houston, and his coauthors. Lymphedema was the main factor affecting quality of life in the analysis.

The analysis included estimates of rates of lymphadenectomy, bilateral mapping, and unilateral mapping, 3-year disease-specific survival, and overall survival, all of which were compared with third-party reimbursement costs at 2016 Medicare rates.

SLN mapping cost $16,401 per patient, while selective LND cost $17,036 per patient and routine LND cost $18,041 per patient. These strategies had quality-adjusted life years of 2.87, 2.81, and 2.79, respectively.

The superior cost-effectiveness of SLN mapping held, even when the researchers altered several of the variables in the model, including assuming open surgery instead of minimally invasive, and altering the assumed risk of lymphedema.

In addition to the possible limitation of making assumptions about SLN mapping and lymphedema, the researchers also pointed to the 3-year survival rates as shorter-term than preferable, driven by the available literature. The quality-adjusted life years did not differ much between the strategies because “most patients with low-risk cancer tend to have good clinical outcomes,” they wrote.

“This adds to the body of literature evaluating the clinical benefits of this strategy and may help health care providers in the decision-making process as they consider which approach to use,” the researchers wrote.

AMSTERDAM – There is an increased relative risk of deliberate self-harm that results in emergency treatment among individuals newly diagnosed with ankylosing spondylitis, according to the results of a large, Canadian population-based study.

A diagnosis of ankylosing spondylitis was associated with a 59% increased risk of deliberate self-harm, compared with no diagnosis (HR = 1.59, 95% CI, 1.16-2.21). While the risk of deliberate self-harm in patients diagnosed with rheumatoid arthritis (RA) was initially elevated, the association was not significant after adjustment for confounding factors (HR = 1.08, 95% CI, 0.87-1.34).

These findings call for heightened awareness among clinicians, study investigator Nigil Haroon, MD, PhD, said in an interview at the European Congress of Rheumatology. “Depression is generally well known to be increased in patients with chronic diseases, especially so with chronic inflammatory rheumatic diseases like ankylosing spondylitis and rheumatoid arthritis,” he said. This may in turn be linked to increased cases of deliberate self-harm, but there have been few studies to determine if this is the case, he said, which may be because it is a relatively rare event in routine clinical practice.

Dr. Haroon, who runs a specialist clinic in ankylosing spondylitis in Toronto, has seen the long-term effects of chronic pain, lack of social support, and inability to sleep on patients’ mood first hand. This is what drove him and other colleagues at the University of Toronto and University Health Network to look at the possibility that this could be linked to an increased risk for depression and perhaps deliberate self-harm among newly diagnosed patients.

To try to estimate the risk, they obtained administrative data on more than 100,000 individuals diagnosed with ankylosing spondylitis or RA in the province of Ontario, Canada, between 2002 and 2014. Excluding those with a history of mental illness or a prior self-harm attempt resulted in the creation of two cohorts of patients – 13,964 with ankylosing spondylitis and 53,240 with RA. Indviduals in these two cohorts were then matched, 4:1, to similar controls in the general population.

The average age of those diagnosed with ankylosing spondylitis was 46 years and of those with RA was 57 years, with more males than females in the ankylosing spondylitis group (57% vs. 43%) and more females than males in the RA group (67% vs. 33%).

The main outcome assessed was the first episode of intentional self-injury or self-poisoning that required emergency treatment that occurred after the diagnosis of ankylosing spondylitis or RA.

Overall, there were 69 deliberate self-harm attempts recorded in the ankylosing spondylitis patient group, compared with 131 attempts in the non-ankylosing spondylitis group. In the RA patient group, there were 129 attempts, and 372 attempts in the non-RA group.

Poisoning was “by far the most common modality” used to intentionally self-harm, used by 67% of patients with ankylosing spondylitis and by 81% of those with RA, Dr. Haroon reported. Contact with a sharp object was the second most common method used to deliberately self-harm by 30% of ankylosing spondylitis patients and 16% of RA patients.

Most (70%) patients were discharged following emergency treatment for a deliberate self-harm attempt, with around 15% of ankylosing spondylitis and 22% of RA patients requiring hospital admission.

“For any chronic disease there is a potential for depression to settle, and we should identify [patients] early, even at the primary care levels itself and try to address it,” Dr. Haroon advised. It’s important to spend time and to develop a good rapport with your patients, he added, which can help them open up and talk about their mood.

The work was funded by the Division of Rheumatology Pfizer Research Chair, University of Toronto. Dr. Haroon reported having no relevant financial disclosures.

AMSTERDAM – Imaging and a positive HLA-B27 test are effective tools for early diagnosis of axial spondyloarthritis in both men and women, according to data from a study of 719 patients with chronic back pain reported at the European Congress of Rheumatology.

Data from previous studies have shown greater severity of axial spondyloarthritis (axSpA) in men, but gender differences at first presentation of the disease have not been well studied, noted Dr. Augusta Ortolan of the University of Padova (Italy) and her colleagues.

SAN DIEGO – New research suggests that pregnant users of both cannabis and tobacco may put their unborn children at higher risk of birth defects and small head circumference than if they used either alone.

Researchers also found that 13% of pregnant Medicaid recipients surveyed reported using both cannabis and tobacco within the past month.

The findings, presented at the annual meeting of the College on Problems of Drug Dependence, point to the importance of asking pregnant patients about cannabis use, especially if they smoke tobacco, said study lead author Victoria H. Coleman-Cowger, PhD, of the research organization Battelle, in an interview.

In some cases, in fact, pregnant women might think that marijuana is healthier than regular cigarettes, said Dr. Coleman-Cowger. She observed this phenomenon while conducting a smoking intervention study at a prenatal clinic that largely served poor, African American women.

“I learned that many participants were also smoking cannabis and felt that there was lower risk associated with cannabis use than with tobacco use,” she said. “Some women were decreasing their use of tobacco during pregnancy but increasing their use of cannabis.”

Dr. Coleman-Cowger’s observations at the clinic inspired the new study, which reports the findings of a convenience survey of 500 pregnant women.

The mean age in the group was 28, and 71% were black. Two-thirds were employed, and 29% were college graduates.

By comparison, the 45 women in the co-user group – who reported both cannabis and tobacco use in the past month – were 93% black, 42% employed, and 7% college graduates. (An additional 39 women reported tobacco use only, and 60 reported cannabis use only.)

Co-use also was correlated with “never married, being in the first trimester of pregnancy, not wanting to be pregnant when they were, past-month other substance use, and more frequent use of both cannabis and tobacco than either exclusive group,” Dr. Coleman-Cowger said.

In adjusted models, co-users were more likely (odds ratio, 5.7; P = .05) to give birth to babies with small head circumference than nonusers. The risks of giving birth to babies with small head circumference also were more likely among the tobacco-only users (OR, 4.8; P = .05) and cannabis-only users (OR, 2.0; P = .05), compared with nonusers. Birth defects also were more likely in the co-user group.

The study did not allow researchers to speculate on whether co-use may multiply risk vs. cannabis or tobacco use alone.

Dr. Coleman-Cowger said in light of the small sample size, the results should be interpreted with caution. One possible confounder is quantity of use, she said. “We did not assess quantity of use, but given our finding that frequency of use is higher among the co-use group, it could be that the co-use group is simply using more of each substance and thus impacting the health consequences.”

Current clinical practice guidelines do not suggest screening for cannabis use in pregnant women. But Dr. Coleman-Cowger said it’s “particularly important when tobacco use has been identified, though in states where substance use is considered child abuse, professional judgment should be utilized in terms of the legal implications of asking about use.”

More research is planned to better understand issues like quantity of use, and reasons why pregnant women co-use cannabis and tobacco, Dr. Coleman-Cowger said.

The National Institute on Drug Abuse funded the study, which Dr. Coleman-Cowger said is part of a larger project “to compare and validate screeners that assess prescription drug misuse and illicit drug use during pregnancy.” The study authors report no relevant disclosures.

The Epstein-Barr virus (EBV) protein can “switch on” risk genes for autoimmune diseases, according to researchers from the National Institute of Allergy and Infectious Diseases. They found that when EBV infects human immune cells, the virus produces a protein (EBNA2) that “recruits” human proteins (transcription factors) to bind to regions of both the EBV genome and the cell’s own genome. Together the viral protein and the human transcription factors change the expression of neighboring viral genes.

In the study, EBNA2 and its related transcription factors activated some of the genes associated with the risk for lupus, multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, type 1 diabetes, juvenile idiopathic arthritis, and celiac disease.

Previous research had also suggested that EBV infection plays a role in autoimmune diseases, particularly lupus. The researchers in the current study speculated that genetic analysis could further explain the relationship. They used a new computational and biochemical technique to sift through genetic and protein data, looking for potential regulatory regions in genes associated with the risk of developing lupus that also bound to EBNA2 and its transcription factors.

“We were surprised to see that nearly half of the locations on the human genome known to contribute to lupus risk were also binding sites for EBNA2,” said John Harley, MD, PhD, lead investigator.

The researchers caution, however, that many of the regulatory genes that contribute to lupus and other autoimmune disorders did not interact with EBNA2, and some individuals with activated regulatory genes do not develop disease.

follicular lymphoma

Autologous and allogeneic hematopoietic stem cell transplantation (HCT) both offer excellent long-term survival in follicular lymphoma (FL) patients who experience early treatment failure, an analysis of a large transplant registry suggests.

Five-year survival rates exceeded 70% for patients who received autologous or matched sibling donor (MSD) transplants, according to the analysis of the Center for International Blood and Marrow Transplant Research (CIBMTR) database. The database included 440 patients who underwent a procedure between 2002 and 2014.

“Until better risk-stratification tools are available for FL, auto-HCT and MSD allo-HCT should be considered as effective treatment options with excellent long-term survival for high-risk patients as defined by early treatment failure,” Sonali M. Smith, MD, of the University of Chicago, and co-investigators wrote in the journal Cancer.

Early treatment failure in FL is associated with worse overall survival. In the National LymphoCare Study (NLCS), patients who received upfront R-CHOP therapy and progressed within 24 months had a 5-year overall survival of 50%, versus 90% for patients without early progression.

By contrast, survival figures in the present study are “provocatively higher” than those in the NLCS, in which only 8 out of 110 patients underwent HCT, Dr Smith and co-authors said.

Dr Smith’s study showed that with a median follow-up of 69 to 73 months, adjusted probability of 5-year overall survival was 70% for autologous and 73% for MSD HCT, versus 49% for matched unrelated donor HCT (P=0.0008).

Ryan C. Lynch, MD, and Ajay K. Gopal, MD, of the Fred Hutchinson Cancer Research Center in Seattle, Washington, said that the finding “convincingly demonstrates” the benefit of transplant in the setting of early treatment failure.

“Select patients (particularly younger patients) with chemoresponsive disease who understand the risk-benefit ratio in comparison with currently approved and experimental therapies still remain good candidates for autologous HCT,” Drs Lynch and Gopal said in an editorial.

“For older patients or patients with comorbidities, we would continue to recommend clinical trials or treatment with an approved PI3K inhibitor,” they added.

The study by Dr Smith and colleagues is not the first to show a benefit of HCT in this clinical scenario. In a recent NLCS/CIBMTR analysis of FL patients, 5-year overall survival was 73% for those undergoing autologous HCT done within a year of early treatment failure, versus 60% for those who did not (P=0.05).

The two studies “collectively suggest that transplantation should be considered in this high-risk group of patients with early relapse,” Dr Smith and co-authors wrote.

Autologous and allogeneic hematopoietic stem cell transplantation (HCT) both offer excellent long-term survival in follicular lymphoma (FL) patients who experience early treatment failure, an analysis of a large transplant registry suggests.

Five-year survival rates exceeded 70% for patients who received autologous or matched sibling donor (MSD) transplants, according to the analysis of the Center for International Blood and Marrow Transplant Research (CIBMTR) database. The database included 440 patients who underwent a procedure between 2002 and 2014.

“Until better risk-stratification tools are available for FL, auto-HCT and MSD allo-HCT should be considered as effective treatment options with excellent long-term survival for high-risk patients as defined by early treatment failure,” Sonali M. Smith, MD, of the University of Chicago, and co-investigators wrote in the journal Cancer.

Early treatment failure in FL is associated with worse overall survival. In the National LymphoCare Study (NLCS), patients who received upfront R-CHOP therapy and progressed within 24 months had a 5-year overall survival of 50%, versus 90% for patients without early progression.

By contrast, survival figures in the present study are “provocatively higher” than those in the NLCS, in which only 8 out of 110 patients underwent HCT, Dr Smith and co-authors said.

Dr Smith’s study showed that with a median follow-up of 69 to 73 months, adjusted probability of 5-year overall survival was 70% for autologous and 73% for MSD HCT, versus 49% for matched unrelated donor HCT (P=0.0008).

Ryan C. Lynch, MD, and Ajay K. Gopal, MD, of the Fred Hutchinson Cancer Research Center in Seattle, Washington, said that the finding “convincingly demonstrates” the benefit of transplant in the setting of early treatment failure.

“Select patients (particularly younger patients) with chemoresponsive disease who understand the risk-benefit ratio in comparison with currently approved and experimental therapies still remain good candidates for autologous HCT,” Drs Lynch and Gopal said in an editorial.

“For older patients or patients with comorbidities, we would continue to recommend clinical trials or treatment with an approved PI3K inhibitor,” they added.

The study by Dr Smith and colleagues is not the first to show a benefit of HCT in this clinical scenario. In a recent NLCS/CIBMTR analysis of FL patients, 5-year overall survival was 73% for those undergoing autologous HCT done within a year of early treatment failure, versus 60% for those who did not (P=0.05).
