Congress extends CHIP, funds opioid crisis response following temporary shutdown
Congress, despite a second shutdown in less than a month, was able to pass a number of financial extenders to fund key health care programs.
The bipartisan spending bill (H.R. 1892), passed in the early morning hours on Feb. 9 by a 71-28 vote in the Senate (16 Republicans and 12 Democrats voted against it, and Sen. John McCain [R-Ariz.] was not present) and a 240-186 vote in the House (67 Republicans and 119 Democrats voted against and 5 representatives did not vote). President Trump signed the bill later that morning.
The spending bill and continuing resolution to fund the government through March 23 includes $6 billion to fund treatment for opioid addiction and other mental health issues, $2 billion in additional funding for the National Institutes of Health, and 4 additional years of funding for the Children’s Health Insurance Program. The additional CHIP funding extends the program for a total of 10 years.
The funding bill also made a technical correction to the Merit-based Incentive Payment System (MIPS) track of the Medicare Quality Payment Program. It removes Part B drug reimbursement from the MIPS payment adjustment, so any positive or negative change to physician payments based on the MIPS score will only be applied to physician fee schedule payments.
The bill also repeals the Independent Payment Advisory Board, a panel created by the Affordable Care Act that would have the power to slash Medicare spending under certain budget circumstances. That board was never convened.
The funding legislation also accelerates closure of the Medicare Part D “donut hole,” the coverage gap in which beneficiaries must pay 100% of medication costs prior to entering catastrophic coverage.
Just over $7 billion was provided for community health centers and Medicare’s therapy caps were repealed.
While the funding bill was written in the Senate with bipartisan input and received bipartisan support, Sen. Rand Paul (R-Ky.) held up votes over objections to the more than $1 trillion it will add to the nation’s debt, as well as for the fact that there was no opportunity to introduce and vote on amendments, leading to an hours-long government shutdown.
There also were concerns about two issues that could have derailed the vote in the House. Democrats wanted to add language to address immigrants brought to this nation illegally as children, while some Republicans did not want to increase the federal debt. However, there were enough votes to pass the funding legislation.

Growing old with HIV: What’s likely, and how can physicians help?
Individuals infected with HIV require early intervention with safe and effective antiretroviral therapy beyond the standard care required for successful aging. The long-term residual inflammation associated with fully suppressive ART must also be addressed, according to a review in the International Journal of Infectious Diseases.
The review was prompted by the increasing number of aging persons with HIV in the population, due to the advent of life-protecting drug treatments.
Gerome V. Escota, MD, and his colleagues at Washington University, St. Louis, assessed the factors faced by the normally aging population and then added an assessment of the path to successful aging given the unique aspects of the HIV infected population (Int J Infect Dis. 2018; 66:56-64).
For example, in San Francisco, 58% of the people with HIV were over 50 years of age by 2014, according to the authors, and those numbers will continue to increase. Such patients will not only be suffering the effects of the normal aging process, but also the potential burden of long-term antiretroviral drug use on their systems.
In addition, even the use of highly-effective antiretroviral therapy does not completely eliminate the inflammatory markers among HIV-infected individuals, and such markers have been associated with increased risk of cardiovascular and other problems. Of particular concern: “It remains unknown whether age-associated inflammation will aggravate residual HIV-associated inflammation in these patients over time,” the authors wrote.
Exacerbated comorbidities that may be a risk among the aging population infected with HIV include cardiovascular disease, osteoporosis, malignancies, chronic liver and kidney disease, and HIV-related neurocognitive disease.
The review was not sponsored and the authors reported that they had no disclosures.

A Veteran With Alcohol Use Disorder and Acute Pancreatitis
Case Presentation. A 23-year-old male U.S. Army veteran with a history of alcohol use disorder and posttraumatic stress disorder (PTSD) presented to the VA Boston Healthcare System (VABHS) West Roxbury campus emergency department (ED) with epigastric abdominal pain in the setting of consuming alcohol. The patient had served in the infantry in Afghanistan during Operation Enduring Freedom. He consumed up to 12 alcoholic drinks per day (both beer and hard liquor) for the past 3 years and had been hospitalized 3 times previously; twice for alcohol detoxification and once for PTSD. He is a former tobacco smoker with fewer than 5 pack-years, he uses marijuana often and does not use IV drugs. In the ED, his physical examination was notable for a heart rate of 130 beats per minute and blood pressure of 161/111 mm Hg. He was alert and oriented and had a mild tremor. The patient was diaphoretic with dry mucous membranes, tenderness to palpation in the epigastrium, and abdominal guarding. A computed tomography (CT) scan of the abdomen revealed acute pancreatitis without necrosis. The patient received 1 L of normal saline and was admitted to the medical ward for presumed alcoholic pancreatitis.
► Rahul Ganatra, MD, MPH, Chief Medical Resident, VABHS and Beth Israel Deaconess Medical Center. Dr. Weber, we care for many young people who drink more than they should and almost none of them end up with alcoholic pancreatitis. What are the relevant risk factors that make individuals like this patient more susceptible to alcoholic pancreatitis?
►Horst Christian Weber, MD, Gastroenterology Service, VABHS, and Assistant Professor of Medicine, Boston University School of Medicine. While we don’t have a good understanding of the precise mechanism of alcoholic pancreatitis, we do know that in the U.S., alcohol consumption is responsible for about one-third of all cases.1 Acute pancreatitis in general may present with a wide range of disease severity. It is the most common cause of gastrointestinal-related hospitalization,2 and the mortality of hospital inpatients with pancreatitis is about 5%.3,4 Therefore, acute pancreatitis represents a prevalent condition with a critical impact on morbidity and mortality. Alcoholic pancreatitis typically occurs after many years of heavy alcohol use, not after a single drinking
► Dr. Ganatra. At this point, the chemistry laboratory paged the admitting resident with the notification that the patient’s blood was grossly lipemic. Ultracentrifugation was performed to separate the lipid layer and his laboratory values result (Table). Notable abnormalities included polycythemia with a hemoglobin of 17.4 g/dL, hyponatremia with a sodium of 129 mmol/L, normal renal function, elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (AST 258 IU/L and ALT 153 IU/L, respectively), hyperbilirubinemia with a total bilirubin of 2.7 mg/dL, and a serum alcohol level of 147 mg/dL. Due to anticipated requirement for a higher level of care, the patient was transferred to the Medical Intensive Care Unit (MICU).
Dr. Breu, can you help us interpret this patient’s numerous laboratory abnormalities? Without yet having the triglyceride level available, how does the fact that the patient’s blood was lipemic affect our interpretation of his labs? What further workup is warranted?
► Anthony Breu, MD, Medical Service, VABHS, Assistant Professor of Medicine, Harvard Medical School. First, the positive alcohol level confirms a recent ingestion. Second, he has elevated transaminases with the AST greater than the ALT, which is consistent with alcoholic liver disease. While the initial assumption is that this patient has alcohol-induced pancreatitis, the elevations in bilirubin and alkaline phosphatase may suggest gallstone pancreatitis, and the lipemic appearing serum could suggest triglyceride-mediated pancreatitis. If the patient does have elevated triglyceride levels, the sodium level may indicate pseudohyponatremia, a laboratory artifact seen if a dilution step is used. To further evaluate the patient, I would obtain a triglyceride level and a right upper quadrant ultrasound. Direct ion-selective electrode analysis of the sodium level can be done with a device used to measure blood gases to exclude pseudohyponatremia.
► Dr. Ganatra. A right upper quadrant ultrasound was obtained in the MICU, which showed hepatic steatosis and hepatomegaly to 19 cm, but no evidence of biliary obstruction by stones or sludge. The common bile duct measured 3.2 mm in diameter. A triglyceride level returned above assay at > 3,392 mg/dL. A review of the medical record revealed a triglyceride level of 105 mg/dL 16 months prior. The Gastroenterology Department was consulted.
Dr. Weber, we now have 2 etiologies for pancreatitis in this patient: alcohol and hypertriglyceridemia. How do each cause pancreatitis? Is it possible to determine in this case which one is the more likely driver?
► Dr. Weber. The mechanism for alcohol-induced pancreatitis is not fully known, but there are several hypotheses. One is that alcohol may increase the synthesis or activation of pancreatic digestive enzymes.6 Another is that metabolites of alcohol are directly toxic to the pancreas.6 Based on the epidemiologic observation that alcoholic pancreatitis usually happens in long-standing users, all we can say is that it is not very likely to be the effect of an acute insult. For hypertriglyceridemic pancreatitis, we believe the injury is due to the toxic effect of free fatty acids in the pancreas liberated by lipolysis of triglycerides by pancreatic lipases. Higher triglycerides are associated with higher risk, suggesting a dose-response relationship: This risk is not greatly increased until triglycerides exceed 500 mg/dL; above 1,000 mg/dL, the risk is about 5%, and above 2,000 mg/dL, the risk is between 10% and 20%.7 In summary, we cannot really determine whether the alcohol or the triglycerides are the main cause of his pancreatitis, but given his markedly elevated triglycerides, he should be treated for hypertriglyceridemic pancreatitis.
►Dr. Ganatra. Dr. Breu, regardless of the underlying etiology, this patient requires treatment. What does the literature suggest as the best course of action regarding crystalloid administration in patients with acute pancreatitis?
►Dr. Breu. There are 2 issues to discuss regarding IV fluids in acute pancreatitis: choice of crystalloid and rate of administration. For the choice of IV fluid, lactated Ringer solution (LR) may be preferred over normal saline (NS). There are both pathophysiologic and evidence-based rationales for this choice. As Dr. Weber alluded to, trypsinogen activation is an important step in the pathogenesis of acute pancreatitis and requires a low pH compartment. As most clinicians have experienced, NS may cause a metabolic acidosis; however, the use of LR may mitigate this. A 2011 randomized clinical trial showed that patients who received LR had less systemic inflammatory response syndrome (SIRS) and lower C-reactive protein (CRP) levels at 24 hours compared with patients who received NS.8 While these are surrogate outcomes, they, along with the theoretical basis, suggest LR is preferred.
Regarding rate, the key is fast and early.9 In my experience, internists often underdose IV rehydration within the first 12 to 24 hours, fail to change the rate based on clinical response, and leave patients on high rates too long. In a patient like this, a rate of 350 cc/h is a reasonable place to start. But, one must reassess response (ie, ensure there is a decrease in hematocrit and/or blood urea nitrogen) every 6 hours and increase the rate as needed. After the first 24 to 48 hours have passed, the rate should be lowered.
►Dr. Ganatra. The patient received 2 mg of IV hydromorphone and a 2 L bolus of LR. This was followed by a continuous infusion of LR at 200 cc/h. Dr. Weber, apart from the standard therapies for pancreatitis, what are our treatment options in hypertriglyceridemic pancreatitis?
►Dr. Weber. In the acute setting, IV insulin with or without dextrose is the most extensively studied therapy. Insulin rapidly decreases triglyceride levels by activating lipoprotein lipase and inhibiting hormone- sensitive lipase. The net effect is reduction in serum triglycerides available to be hydrolyzed to free fatty acids in the pancreas.7 For severe cases (ie, where acute pancreatitis is accompanied by hypocalcemia, lactic acidosis or a markedly elevated lipase), apheresis with therapeutic plasma exchange to more rapidly reduce triglyceride concentration is the preferred therapy. The goal is to reduce triglycerides to levels
►Dr. Ganatra. Due to the possibility that the patient would require apheresis, which was not available at the VABHS West Roxbury campus, the patient was transferred to an affiliate hospital. The patient was started on 10% dextrose at 300 cc/h and an IV insulin infusion. His triglycerides fell to < 500 mg/dL over the subsequent 48 hours, and ultimately, apheresis was not required. Enteral nutrition by nasogastric (NG) tube was initiated on hospital day 6. The patient’s hospital course was notable for acute respiratory distress syndrome that required intubation for 7 days, hyperbilirubinemia (with a peak bilirubin of 10.5 mg/dL), acute kidney injury (with a peak creatinine 4.7 mg/dL), fever without an identified infectious source, alcohol withdrawal syndrome that required phenobarbital, and delirium. Nine days later, he was transferred back to the VABHS West Roxbury campus. His condition stabilized, and he was transferred to the medical floor. On hospital day 14, the patient’s mental status improved, and he began tolerating oral nutrition.
Dr. Breu, over the years, the standard of care regarding when to start enteral nutrition in pancreatitis has changed considerably. This patient received enteral nutrition via NG tube but also had periods of being NPO (nothing by mouth) for up to 6 days. What is the current best practice for timing of initiating enteral nutrition in acute pancreatitis?
►Dr. Breu. It is true that the standard of care has changed and continues to evolve. Many decades ago, patients with acute pancreatitis would routinely undergo NG tube suction to reduce delivery of gastric contents to the duodenum, thereby decreasing pancreas activation, allowing it to rest.11 The NG tube also allowed for decompression of any ileus that had formed. Beginning in the 1970s, several clinical trials were performed, showing that NG tube suction was no better than simply making the patient NPO.12,13 More recently, we have begun to move toward earlier feeding. Again, there is a pathophysiologic rationale (bowel rest is associated with intestinal atrophy, predisposing to bacterial translocation and resulting infectious complications) and increasing evidence supporting this practice.9 Even in severe pancreatitis, hunger may be used to initiate oral intake.14
►Dr. Ganatra. On hospital day 16, the patient developed sudden-onset right-sided back and flank pain, and his hemoglobin dropped to 6.1 mg/dL, which required transfusion of packed red blood cells. He remained afebrile and hemodynamically stable. Dr. Weber, what are the major complications of acute pancreatitis, and when should we suspect them? Should we be worried about complications of pancreatitis in this patient?
►Dr. Weber. Organ failure in the acute setting can occur due to activation of cytokine cascades and the systemic inflammatory response syndrome and is described by clinical and radiologic criteria called the Atlanta Classification.15 Apart from organ failure, the most serious complications of acute pancreatitis are necrosis of pancreatic tissue leading to walled-off pancreatic necrosis and the formation of peripancreatic fluid collections and pseudocysts, which occur in about 15% of patients with acute pancreatitis. These complications are serious because they can become infected, which portends a higher mortality and in some cases require surgical resection.
Other complications of acute pancreatitis include pseudoaneurysm formation, which is when a vessel bleeds into a pancreatic pseudocyst, and thromboses of the splenic, portal, or mesenteric veins. Thrombotic complications may occur in up to half of patients with pancreatic necrosis but are uncommon without some degree of necrosis.16 No necrosis was noted on this patient’s initial CT scan, so the probability of thrombosis is low. Also, as it takes several weeks for pseudocyst formation to occur, a bleeding pseudoaneurysm is unlikely at this early stage. Therefore, a complication of pancreatitis is unlikely in this patient, and evaluation for other causes of abdominal pain should be considered.
►Dr. Ganatra. A noncontrast CT of the abdomen and pelvis was obtained and revealed no evidence of complications or other acute pathology. His pain was managed conservatively, and hemoglobin remained stable. Over the next 5 days, the patient’s symptoms gradually resolved, his oral intake improved, and he was discharged home on gemfibrozil 600 mg twice daily 19 days after admission. He declined psychiatry follow-up for his PTSD, and after discharge he did not keep his scheduled gastroenterology (GI) follow-up appointment. Four months later, the patient presented again with epigastric abdominal pain similar to his initial presentation. The patient had resumed drinking, stating that “alcohol is the only thing that helps [with the PTSD].” He had not been taking the gemfibrozil. He was admitted with a recurrent episode of pancreatitis; however, his triglycerides on admission were 119 mg/dL.
Dr. Weber, this patient’s triglycerides declined rapidly over a period of just 4 months with questionable adherence to gemfibrozil. However, he was admitted again with another episode of pancreatitis, this time in the setting of alcohol use alone without markedly elevated triglycerides. What do we know about recurrence risk for pancreatitis? Are some etiologies of pancreatitis more likely to present with recurrent attacks than are others?
►Dr. Weber. The rate of recurrence following an episode of acute pancreatitis varies according to the cause, but in general, about 20% to 30% of patients will experience a recurrence, and 5% to 10% will go on to develop chronic pancreatitis.17 Alcoholic pancreatitis does carry a higher risk of recurrence than pancreatitis due to other causes; the risk is as high as 50%. Not surprisingly, recurrence of acute pancreatitis increases risk for development of chronic pancreatitis. As this patient is a smoker, it is worth noting that smoking potentiates pancreatic damage from alcohol and increases the risk for both recurrent and chronic pancreatitis.5
►Dr. Ganatra. The patient was treated with IV hydromorphone and IV LR at 350 cc/h. Oral nutrition was begun immediately. He manifested no organ dysfunction, and his symptoms improved over the course of 48 hours. He was discharged home with psychiatry and GI follow-up scheduled. Dr. Breu and Dr. Weber, how should we counsel this patient to reduce his risk of recurrent attacks of pancreatitis in the future, and what options do we have for pharmacotherapy to decrease his risk?
►Dr. Breu. I’ll let Dr. Weber comment on mitigating the risk of hypertriglyceride-induced pancreatitis and reserve my comments to pharmacotherapy in alcohol use disorder. This patient may be a candidate for naltrexone therapy, either in oral or intramuscular formulations. Both have been showed to reduce the risk of returning to heavy drinking and may be particularly beneficial in those with a family history.18,19 Acamprosate is also an option.
►Dr. Weber. Data on recurrence risk in hypertriglyceridemic pancreatitis are limited, but there are case reports suggesting that a fatty diet and alcohol use are implicated in recurrence.20 I would counsel the patient on lifestyle modifications that are known to reduce this risk. I agree with Dr. Breu that devoting our efforts to helping him reduce or eliminate his alcohol consumption is the single most important thing we can do to reduce his risk for recurrent attacks. Since the patient reports that he drinks alcohol in order to cope with his PTSD, establishing care with a mental health provider to address this is of the utmost importance. In addition, smoking cessation and promoting medication adherence with gemfibrozil will also reduce risk for future episodes, but continued alcohol use is his strongest risk factor.
►Dr. Ganatra. After discharge, the patient engaged with outpatient psychiatry and GI. He still reports feeling that alcohol is the only thing that alleviates his PTSD and anxiety symptoms. He is not currently interested in pharmacotherapy for cessation of alcohol use.

Case Presentation. A 23-year-old male U.S. Army veteran with a history of alcohol use disorder and posttraumatic stress disorder (PTSD) presented to the VA Boston Healthcare System (VABHS) West Roxbury campus emergency department (ED) with epigastric abdominal pain in the setting of consuming alcohol. The patient had served in the infantry in Afghanistan during Operation Enduring Freedom. He consumed up to 12 alcoholic drinks per day (both beer and hard liquor) for the past 3 years and had been hospitalized 3 times previously; twice for alcohol detoxification and once for PTSD. He is a former tobacco smoker with fewer than 5 pack-years, he uses marijuana often and does not use IV drugs. In the ED, his physical examination was notable for a heart rate of 130 beats per minute and blood pressure of 161/111 mm Hg. He was alert and oriented and had a mild tremor. The patient was diaphoretic with dry mucous membranes, tenderness to palpation in the epigastrium, and abdominal guarding. A computed tomography (CT) scan of the abdomen revealed acute pancreatitis without necrosis. The patient received 1 L of normal saline and was admitted to the medical ward for presumed alcoholic pancreatitis.
► Rahul Ganatra, MD, MPH, Chief Medical Resident, VABHS and Beth Israel Deaconess Medical Center. Dr. Weber, we care for many young people who drink more than they should and almost none of them end up with alcoholic pancreatitis. What are the relevant risk factors that make individuals like this patient more susceptible to alcoholic pancreatitis?
►Horst Christian Weber, MD, Gastroenterology Service, VABHS, and Assistant Professor of Medicine, Boston University School of Medicine. While we don’t have a good understanding of the precise mechanism of alcoholic pancreatitis, we do know that in the U.S., alcohol consumption is responsible for about one-third of all cases.1 Acute pancreatitis in general may present with a wide range of disease severity. It is the most common cause of gastrointestinal-related hospitalization,2 and the mortality of hospital inpatients with pancreatitis is about 5%.3,4 Therefore, acute pancreatitis represents a prevalent condition with a critical impact on morbidity and mortality. Alcoholic pancreatitis typically occurs after many years of heavy alcohol use, not after a single drinking
► Dr. Ganatra. At this point, the chemistry laboratory paged the admitting resident with the notification that the patient’s blood was grossly lipemic. Ultracentrifugation was performed to separate the lipid layer and his laboratory values result (Table). Notable abnormalities included polycythemia with a hemoglobin of 17.4 g/dL, hyponatremia with a sodium of 129 mmol/L, normal renal function, elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (AST 258 IU/L and ALT 153 IU/L, respectively), hyperbilirubinemia with a total bilirubin of 2.7 mg/dL, and a serum alcohol level of 147 mg/dL. Due to anticipated requirement for a higher level of care, the patient was transferred to the Medical Intensive Care Unit (MICU).
Dr. Breu, can you help us interpret this patient’s numerous laboratory abnormalities? Without yet having the triglyceride level available, how does the fact that the patient’s blood was lipemic affect our interpretation of his labs? What further workup is warranted?
► Anthony Breu, MD, Medical Service, VABHS, Assistant Professor of Medicine, Harvard Medical School. First, the positive alcohol level confirms a recent ingestion. Second, he has elevated transaminases with the AST greater than the ALT, which is consistent with alcoholic liver disease. While the initial assumption is that this patient has alcohol-induced pancreatitis, the elevations in bilirubin and alkaline phosphatase may suggest gallstone pancreatitis, and the lipemic appearing serum could suggest triglyceride-mediated pancreatitis. If the patient does have elevated triglyceride levels, the sodium level may indicate pseudohyponatremia, a laboratory artifact seen if a dilution step is used. To further evaluate the patient, I would obtain a triglyceride level and a right upper quadrant ultrasound. Direct ion-selective electrode analysis of the sodium level can be done with a device used to measure blood gases to exclude pseudohyponatremia.
► Dr. Ganatra. A right upper quadrant ultrasound was obtained in the MICU, which showed hepatic steatosis and hepatomegaly to 19 cm, but no evidence of biliary obstruction by stones or sludge. The common bile duct measured 3.2 mm in diameter. A triglyceride level returned above assay at > 3,392 mg/dL. A review of the medical record revealed a triglyceride level of 105 mg/dL 16 months prior. The Gastroenterology Department was consulted.
Dr. Weber, we now have 2 etiologies for pancreatitis in this patient: alcohol and hypertriglyceridemia. How do each cause pancreatitis? Is it possible to determine in this case which one is the more likely driver?
► Dr. Weber. The mechanism for alcohol-induced pancreatitis is not fully known, but there are several hypotheses. One is that alcohol may increase the synthesis or activation of pancreatic digestive enzymes.6 Another is that metabolites of alcohol are directly toxic to the pancreas.6 Based on the epidemiologic observation that alcoholic pancreatitis usually happens in long-standing users, all we can say is that it is not very likely to be the effect of an acute insult. For hypertriglyceridemic pancreatitis, we believe the injury is due to the toxic effect of free fatty acids in the pancreas liberated by lipolysis of triglycerides by pancreatic lipases. Higher triglycerides are associated with higher risk, suggesting a dose-response relationship: This risk is not greatly increased until triglycerides exceed 500 mg/dL; above 1,000 mg/dL, the risk is about 5%, and above 2,000 mg/dL, the risk is between 10% and 20%.7 In summary, we cannot really determine whether the alcohol or the triglycerides are the main cause of his pancreatitis, but given his markedly elevated triglycerides, he should be treated for hypertriglyceridemic pancreatitis.
►Dr. Ganatra. Dr. Breu, regardless of the underlying etiology, this patient requires treatment. What does the literature suggest as the best course of action regarding crystalloid administration in patients with acute pancreatitis?
►Dr. Breu. There are 2 issues to discuss regarding IV fluids in acute pancreatitis: choice of crystalloid and rate of administration. For the choice of IV fluid, lactated Ringer solution (LR) may be preferred over normal saline (NS). There are both pathophysiologic and evidence-based rationales for this choice. As Dr. Weber alluded to, trypsinogen activation is an important step in the pathogenesis of acute pancreatitis and requires a low pH compartment. As most clinicians have experienced, NS may cause a metabolic acidosis; however, the use of LR may mitigate this. A 2011 randomized clinical trial showed that patients who received LR had less systemic inflammatory response syndrome (SIRS) and lower C-reactive protein (CRP) levels at 24 hours compared with patients who received NS.8 While these are surrogate outcomes, they, along with the theoretical basis, suggest LR is preferred.
Regarding rate, the key is fast and early.9 In my experience, internists often underdose IV rehydration within the first 12 to 24 hours, fail to change the rate based on clinical response, and leave patients on high rates too long. In a patient like this, a rate of 350 cc/h is a reasonable place to start. But, one must reassess response (ie, ensure there is a decrease in hematocrit and/or blood urea nitrogen) every 6 hours and increase the rate as needed. After the first 24 to 48 hours have passed, the rate should be lowered.
►Dr. Ganatra. The patient received 2 mg of IV hydromorphone and a 2 L bolus of LR. This was followed by a continuous infusion of LR at 200 cc/h. Dr. Weber, apart from the standard therapies for pancreatitis, what are our treatment options in hypertriglyceridemic pancreatitis?
►Dr. Weber. In the acute setting, IV insulin with or without dextrose is the most extensively studied therapy. Insulin rapidly decreases triglyceride levels by activating lipoprotein lipase and inhibiting hormone- sensitive lipase. The net effect is reduction in serum triglycerides available to be hydrolyzed to free fatty acids in the pancreas.7 For severe cases (ie, where acute pancreatitis is accompanied by hypocalcemia, lactic acidosis or a markedly elevated lipase), apheresis with therapeutic plasma exchange to more rapidly reduce triglyceride concentration is the preferred therapy. The goal is to reduce triglycerides to levels
►Dr. Ganatra. Due to the possibility that the patient would require apheresis, which was not available at the VABHS West Roxbury campus, the patient was transferred to an affiliate hospital. The patient was started on 10% dextrose at 300 cc/h and an IV insulin infusion. His triglycerides fell to < 500 mg/dL over the subsequent 48 hours, and ultimately, apheresis was not required. Enteral nutrition by nasogastric (NG) tube was initiated on hospital day 6. The patient’s hospital course was notable for acute respiratory distress syndrome that required intubation for 7 days, hyperbilirubinemia (with a peak bilirubin of 10.5 mg/dL), acute kidney injury (with a peak creatinine 4.7 mg/dL), fever without an identified infectious source, alcohol withdrawal syndrome that required phenobarbital, and delirium. Nine days later, he was transferred back to the VABHS West Roxbury campus. His condition stabilized, and he was transferred to the medical floor. On hospital day 14, the patient’s mental status improved, and he began tolerating oral nutrition.
Dr. Breu, over the years, the standard of care regarding when to start enteral nutrition in pancreatitis has changed considerably. This patient received enteral nutrition via NG tube but also had periods of being NPO (nothing by mouth) for up to 6 days. What is the current best practice for timing of initiating enteral nutrition in acute pancreatitis?
►Dr. Breu. It is true that the standard of care has changed and continues to evolve. Many decades ago, patients with acute pancreatitis would routinely undergo NG tube suction to reduce delivery of gastric contents to the duodenum, thereby decreasing pancreas activation, allowing it to rest.11 The NG tube also allowed for decompression of any ileus that had formed. Beginning in the 1970s, several clinical trials were performed, showing that NG tube suction was no better than simply making the patient NPO.12,13 More recently, we have begun to move toward earlier feeding. Again, there is a pathophysiologic rationale (bowel rest is associated with intestinal atrophy, predisposing to bacterial translocation and resulting infectious complications) and increasing evidence supporting this practice.9 Even in severe pancreatitis, hunger may be used to initiate oral intake.14
►Dr. Ganatra. On hospital day 16, the patient developed sudden-onset right-sided back and flank pain, and his hemoglobin dropped to 6.1 mg/dL, which required transfusion of packed red blood cells. He remained afebrile and hemodynamically stable. Dr. Weber, what are the major complications of acute pancreatitis, and when should we suspect them? Should we be worried about complications of pancreatitis in this patient?
►Dr. Weber. Organ failure in the acute setting can occur due to activation of cytokine cascades and the systemic inflammatory response syndrome and is described by clinical and radiologic criteria called the Atlanta Classification.15 Apart from organ failure, the most serious complications of acute pancreatitis are necrosis of pancreatic tissue leading to walled-off pancreatic necrosis and the formation of peripancreatic fluid collections and pseudocysts, which occur in about 15% of patients with acute pancreatitis. These complications are serious because they can become infected, which portends a higher mortality and in some cases require surgical resection.
Other complications of acute pancreatitis include pseudoaneurysm formation, which is when a vessel bleeds into a pancreatic pseudocyst, and thromboses of the splenic, portal, or mesenteric veins. Thrombotic complications may occur in up to half of patients with pancreatic necrosis but are uncommon without some degree of necrosis.16 No necrosis was noted on this patient’s initial CT scan, so the probability of thrombosis is low. Also, as it takes several weeks for pseudocyst formation to occur, a bleeding pseudoaneurysm is unlikely at this early stage. Therefore, a complication of pancreatitis is unlikely in this patient, and evaluation for other causes of abdominal pain should be considered.
►Dr. Ganatra. A noncontrast CT of the abdomen and pelvis was obtained and revealed no evidence of complications or other acute pathology. His pain was managed conservatively, and hemoglobin remained stable. Over the next 5 days, the patient’s symptoms gradually resolved, his oral intake improved, and he was discharged home on gemfibrozil 600 mg twice daily 19 days after admission. He declined psychiatry follow-up for his PTSD, and after discharge he did not keep his scheduled gastroenterology (GI) follow-up appointment. Four months later, the patient presented again with epigastric abdominal pain similar to his initial presentation. The patient had resumed drinking, stating that “alcohol is the only thing that helps [with the PTSD].” He had not been taking the gemfibrozil. He was admitted with a recurrent episode of pancreatitis; however, his triglycerides on admission were 119 mg/dL.
Dr. Weber, this patient’s triglycerides declined rapidly over a period of just 4 months with questionable adherence to gemfibrozil. However, he was admitted again with another episode of pancreatitis, this time in the setting of alcohol use alone without markedly elevated triglycerides. What do we know about recurrence risk for pancreatitis? Are some etiologies of pancreatitis more likely to present with recurrent attacks than are others?
►Dr. Weber. The rate of recurrence following an episode of acute pancreatitis varies according to the cause, but in general, about 20% to 30% of patients will experience a recurrence, and 5% to 10% will go on to develop chronic pancreatitis.17 Alcoholic pancreatitis does carry a higher risk of recurrence than pancreatitis due to other causes; the risk is as high as 50%. Not surprisingly, recurrence of acute pancreatitis increases risk for development of chronic pancreatitis. As this patient is a smoker, it is worth noting that smoking potentiates pancreatic damage from alcohol and increases the risk for both recurrent and chronic pancreatitis.5
►Dr. Ganatra. The patient was treated with IV hydromorphone and IV LR at 350 cc/h. Oral nutrition was begun immediately. He manifested no organ dysfunction, and his symptoms improved over the course of 48 hours. He was discharged home with psychiatry and GI follow-up scheduled. Dr. Breu and Dr. Weber, how should we counsel this patient to reduce his risk of recurrent attacks of pancreatitis in the future, and what options do we have for pharmacotherapy to decrease his risk?
►Dr. Breu. I’ll let Dr. Weber comment on mitigating the risk of hypertriglyceride-induced pancreatitis and reserve my comments to pharmacotherapy in alcohol use disorder. This patient may be a candidate for naltrexone therapy, either in oral or intramuscular formulations. Both have been showed to reduce the risk of returning to heavy drinking and may be particularly beneficial in those with a family history.18,19 Acamprosate is also an option.
►Dr. Weber. Data on recurrence risk in hypertriglyceridemic pancreatitis are limited, but there are case reports suggesting that a fatty diet and alcohol use are implicated in recurrence.20 I would counsel the patient on lifestyle modifications that are known to reduce this risk. I agree with Dr. Breu that devoting our efforts to helping him reduce or eliminate his alcohol consumption is the single most important thing we can do to reduce his risk for recurrent attacks. Since the patient reports that he drinks alcohol in order to cope with his PTSD, establishing care with a mental health provider to address this is of the utmost importance. In addition, smoking cessation and promoting medication adherence with gemfibrozil will also reduce risk for future episodes, but continued alcohol use is his strongest risk factor.
►Dr. Ganatra. After discharge, the patient engaged with outpatient psychiatry and GI. He still reports feeling that alcohol is the only thing that alleviates his PTSD and anxiety symptoms. He is not currently interested in pharmacotherapy for cessation of alcohol use.

HIV Treatment: OK to Take a Break?
Antiretroviral therapy (ART) keeps viral load of HIV at undetectable levels. The key is taking it daily. But it may be possible for patients to temporarily stop ART without long-lasting or irreversible damage to the immune system.
That approach is called analytical treatment interruption (ATI), and it is the subject of a study by NIH researchers at the National Institute of Allergy and Infectious Diseases. They analyzed blood samples from 10 volunteers who participated in a clinical trial that evaluated whether infusions of a broadly neutralizing antibody could control HIV in the absence of ART.
During the trial, participants temporarily stopped taking ART, resuming 22 to 115 days after stopping. In that hiatus, HIV reservoirs expanded and viral load increased. The researchers also observed abnormalities in the participants’ immune cells. However, 6 to 12 months after the participants resumed ART, the size of the HIV reservoirs and the immune parameters returned to the pre-ATI levels.
These findings support the use of ATI in clinical trials of therapeutic strategies aimed at achieving sustained ART-free remission, the researchers say. They are now conducting a clinical trial to monitor the impact of short-term ATI on a variety of parameters in people living with HIV.

Drug may be option for B- and T-cell lymphomas
LA JOLLA, CA—The EZH1/2 inhibitor DS-3201b could be a novel therapeutic option for non-Hodgkin lymphoma (NHL), according to a speaker at the 10th Annual T-cell Lymphoma Forum.
DS-3201b was considered well tolerated in a phase 1 study of Japanese patients with relapsed/refractory NHL.
In addition, DS-3201b demonstrated activity against B- and T-cell lymphomas, producing an overall response rate of 59%.
Kunihiro Tsukasaki, MD, PhD, of Saitama Medical University in Moroyama, Saitama, Japan, presented these results at the meeting.
The trial was sponsored by Daiichi Sankyo Co., Ltd.
Dr Tsukasaki presented data on 18 patients with relapsed/refractory NHL.
The 12 B-cell lymphoma patients had follicular lymphoma (n=5), diffuse large B-cell lymphoma (n=3), MALT lymphoma (n=2), nodal marginal zone lymphoma (n=1), and lymphoplasmacytic lymphoma (n=1).
The 6 patients with T-cell lymphoma had peripheral T-cell lymphoma not otherwise specified (n=2), angioimmunoblastic T-cell lymphoma (n=2), and adult T-cell leukemia/lymphoma (n=2).
The patients’ median age was 67 (range, 44-75), and 10 were female. All patients had an ECOG performance status of 0 (72%) or 1 (28%).
Patients had a median of 2 prior chemotherapy regimens (range, 1-8).
For this study, they received DS-3201b at 150 mg (n=7), 200 mg (n=9), or 300 mg (n=2). They received the drug once daily in 28-day cycles until they progressed or experienced unacceptable toxicity.
DLTs and AEs
Dose-limiting toxicities (DLTs) were evaluated in cycle 1. All 18 patients were evaluable for DLT assessment.
There were 4 treatment-emergent adverse events (AEs) that met the definition of DLTs:
- 3 cases of grade 4 platelet count decrease (n=1 at 200 mg, n=2 at 300 mg)
- 1 case of grade 3 anemia requiring blood transfusion (at 300 mg).
All 4 DLTs led to treatment interruption.
There were 5 serious AEs reported in 3 patients. Only one of these—pneumocystis jiroveci pneumonia—was considered related to DS-3201b.
Hematologic AEs included decreases in platelets (grade 1-4), lymphocytes (grade 1-4), neutrophils (grade 2-4), and white blood cells (grade 2-3), as well as anemia (grade 1-3).
Other AEs (all grade 1/2) included dysgeusia, alopecia, diarrhea, decreased appetite, alanine aminotransferase increase, aspartate aminotransferase increase, nasopharyngitis, rash, and dry skin.
No deaths had been reported as of the data cutoff last November.
Responses
Seventeen patients were evaluable for response.
The overall response rate was 59%, with 1 patient achieving a complete response (CR) and 9 achieving a partial response (PR). Four patients had stable disease (SD), and 3 progressed.
Among the T-cell lymphoma patients, 1 had a CR, 4 had PRs, and 1 progressed. The complete responder had angioimmunoblastic T-cell lymphoma, and the patient who progressed had adult T-cell leukemia/lymphoma.
Among the B-cell lymphoma patients, 5 had PRs, 4 had SD, and 2 progressed.
Dr Tsukasaki said DS-3201b has demonstrated early clinical activity and therefore has the potential to be a novel therapeutic option for B-cell and T-cell lymphomas. However, further evaluation is warranted to determine the optimal dosing regimen and target diseases.

Factor IX product launched in US
The recombinant, GlycoPEGylated coagulation factor IX product Rebinyn® is now available in the US for the treatment of patients with hemophilia B.
Last May, Rebinyn was approved by the US Food and Drug Administration for on-demand treatment and control of bleeding episodes as well as perioperative management of bleeding in adults and children with hemophilia B.
The product is not approved for routine prophylaxis or immune tolerance induction in hemophilia B patients.
The full prescribing information is available at www.Rebinyn.com.
Rebinyn is also approved for use in the European Union, where it is known as nonacog beta pegol or by the brand name Refixia.
There, the product is approved for use as prophylaxis, for on-demand treatment of bleeding, and for control of bleeding related to surgical procedures in adolescents (older than 12 years of age) and adults with hemophilia B.
Trial results
The US and European approvals of nonacog beta pegol (N9-GP) were based on results from the paradigm™ clinical trials. Results from the paradigm 4 trial were published in Thrombosis Research in May 2016.
Paradigm 4 was an extension trial enrolling patients who had participated in the phase 3 trials paradigm 2 and paradigm 3.
In paradigm 2, researchers assessed N9-GP as treatment and prophylaxis in previously treated patients with hemophilia B. In paradigm 3, researchers assessed N9-GP in hemophilia B patients undergoing surgical procedures.
Paradigm 4 included 71 patients (ages 13 to 70) who continued to receive N9-GP as on-demand treatment (40 IU/kg for mild/moderate bleeds and 80 IU/kg for severe bleeds) or prophylaxis (10 IU/kg or 40 IU/kg once-weekly). Sixty-five patients completed treatment.
Safety
None of the patients developed factor IX inhibitors. Two patients had transient binding antibodies to N9-GP, but there was no sign that these antibodies had an inhibitory effect.
Four patients developed anti-CHO antibodies, but only 2 of these patients were still positive for these antibodies at the end of the trial.
There were a total of 155 adverse events. However, only 4 of these (in 3 patients) were considered possibly or probably related to N9-GP.
These events consisted of an injection site rash in 1 patient, 2 overdoses in 1 patient, and neutropenia in 1 patient. The rash and neutropenia resolved, and the patient who overdosed recovered without complications.
Efficacy
The researchers said the success rate for the treatment of reported bleeds was 94.6%. Most bleeds (87.9%) were resolved with a single injection of N9-GP, but 9.2% required 2 injections, and 2.9% required 3 or 4 injections.
The median annualized bleeding rate for patients on prophylaxis was 1.05 (interquartile range [IQR], 0.00–2.20) overall. It was 1.36 (IQR, 0.00-2.23) for the 10 IU/kg arm and 1.00 (IQR, 0.00-2.03) for the 40 IU/kg arm.
There were 14 patients on prophylaxis who underwent 23 minor surgical procedures.
The hemostatic response was considered “excellent” (better than expected/predicted for the procedure in question) in 19 procedures and “good” (as expected) in 2 procedures. In the remaining 2 procedures, hemostatic responses were not determined.

There, the product is approved for use as prophylaxis, for on-demand treatment of bleeding, and for control of bleeding related to surgical procedures in adolescents (older than 12 years of age) and adults with hemophilia B.
Trial results
The US and European approvals of nonacog beta pegol (N9-GP) were based on results from the paradigm™ clinical trials. Results from the paradigm 4 trial were published in Thrombosis Research in May 2016.
Paradigm 4 was an extension trial enrolling patients who had participated in the phase 3 trials paradigm 2 and paradigm 3.
In paradigm 2, researchers assessed N9-GP as treatment and prophylaxis in previously treated patients with hemophilia B. In paradigm 3, researchers assessed N9-GP in hemophilia B patients undergoing surgical procedures.
Paradigm 4 included 71 patients (ages 13 to 70) who continued to receive N9-GP as on-demand treatment (40 IU/kg for mild/moderate bleeds and 80 IU/kg for severe bleeds) or prophylaxis (10 IU/kg or 40 IU/kg once-weekly). Sixty-five patients completed treatment.
Safety
None of the patients developed factor IX inhibitors. Two patients had transient binding antibodies to N9-GP, but there was no sign that these antibodies had an inhibitory effect.
Four patients developed anti-CHO antibodies, but only 2 of these patients were still positive for these antibodies at the end of the trial.
There were a total of 155 adverse events. However, only 4 of these (in 3 patients) were considered possibly or probably related to N9-GP.
These events consisted of an injection site rash in 1 patient, 2 overdoses in 1 patient, and neutropenia in 1 patient. The rash and neutropenia resolved, and the patient who overdosed recovered without complications.
Efficacy
The researchers said the success rate for the treatment of reported bleeds was 94.6%. Most bleeds (87.9%) were resolved with a single injection of N9-GP, but 9.2% required 2 injections, and 2.9% required 3 or 4 injections.
The median annualized bleeding rate for patients on prophylaxis was 1.05 (interquartile range [IQR], 0.00–2.20) overall. It was 1.36 (IQR, 0.00-2.23) for the 10 IU/kg arm and 1.00 (IQR, 0.00-2.03) for the 40 IU/kg arm.
There were 14 patients on prophylaxis who underwent 23 minor surgical procedures.
The hemostatic response was considered “excellent” (better than expected/predicted for the procedure in question) in 19 procedures and “good” (as expected) in 2 procedures. In the remaining 2 procedures, hemostatic responses were not determined.
Assay identifies actionable mutations in lymphoid malignancies
Researchers say hybrid capture sequencing is an accurate and sensitive method for identifying actionable gene mutations in lymphoid malignancies.
This method revealed potentially actionable mutations in 91% of patients studied, who had diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), or chronic lymphocytic leukemia (CLL).
The researchers therefore believe hybrid capture sequencing will bring the benefits of precision diagnosis and individualized therapy to patients with lymphoid malignancies.
“To realize the benefits of the most recent progress in cancer genomics, clinical implementation of precision medicine approaches is needed in the form of novel biomarker assays,” said study author Christian Steidl, MD, of the University of British Columbia in Vancouver, Canada.
“Fully implemented targeted sequencing-based assays in routine diagnostic pathology laboratories are currently lacking in lymphoid cancer care. Our findings demonstrate the feasibility and outline the clinical utility of integrating a lymphoma-specific pipeline into personalized cancer care.”
Dr Steidl and his colleagues reported these findings in The Journal of Molecular Diagnostics.
The researchers first compared capture hybridization and amplicon sequencing using samples from 8 patients with lymphoma. Fresh-frozen and formalin-fixed, paraffin-embedded tumor samples were sequenced using a panel of 20 lymphoma-specific genes.
The team found that capture hybridization provided “deep, more uniform coverage” and yielded “higher sensitivity for variant calling” than amplicon sequencing.
The researchers then developed a targeted sequencing pipeline using a 32-gene panel. The panel was developed with input from a group of 6 specialists who kept updating it based on the latest available information.
“This allows for continuous integration of additional gene features as our knowledge base improves,” Dr Steidl noted.
He and his colleagues then applied the hybrid capture sequencing assay and 32-gene panel to tissues from 219 patients—114 with FL, 76 with DLBCL, and 29 with CLL—who were treated in British Columbia between 2013 and 2016.
Results revealed at least one actionable mutation in 91% of the tumors. And the assay uncovered subtype-specific mutational profiles that were highly similar to published mutational profiles for FL, DLBCL, and CLL.
Furthermore, the assay had 93% concordance with whole-genome sequencing.
“Our developed assay harnesses the power of modern sequencing for clinical diagnostics purposes and potentially better deployment of novel treatments in lymphoid cancers,” Dr Steidl said. “We believe our study will help establish evidence-based approaches to decision making in lymphoid cancer care.”
“The next steps are to implement sequencing-based biomarker assays, such as reported in our study, in accredited pathology laboratories. Toward the goal of biomarker-driven clinical decision making, testing of potentially predictive biomarker assays is needed alongside clinical trials investigating novel cancer therapeutics.”

Azacitidine now available in China
Azacitidine for injection (Vidaza®) is now available in China.
The nucleoside metabolic inhibitor was approved in China to treat patients with intermediate-2/high-risk myelodysplastic syndromes (MDS), acute myeloid leukemia (AML) with 20% to 30% bone marrow blasts, and chronic myelomonocytic leukemia (CMML).
Azacitidine for injection is marketed in China by BeiGene Ltd. under an exclusive license from Celgene Corporation.
“Vidaza is the only approved hypomethylating agent shown to prolong survival for patients with MDS and the first new treatment for MDS patients approved in China since 2009,” said John V. Oyler, founder, chief executive officer, and chairman of BeiGene.
“We are excited to announce that the first prescription was made in January 2018. From now on, Chinese patients can benefit from Vidaza in hospitals around China.”
Azacitidine was evaluated in a global phase 3 trial of patients with intermediate-2- and high-risk MDS, CMML, or AML (AZA-001). Results from this trial were published in The Lancet Oncology in 2009.
Patients were randomized to receive azacitidine plus best supportive care (BSC, n=179) or conventional care regimens plus BSC (105 to BSC alone, 49 to low-dose cytarabine, and 25 to chemotherapy with cytarabine and anthracycline).
Azacitidine was given subcutaneously at a dose of 75 mg/m2 daily for 7 consecutive days every 28 days until disease progression, relapse after response, or unacceptable toxicity.
The median overall survival was 24.5 months with azacitidine, compared to 15 months for patients treated with conventional care regimens.
There was a higher hematologic response rate in the azacitidine arm than the conventional care arm—29% and 12%, respectively.
In the azacitidine group, 45% of patients who were dependent on red blood cell transfusions at baseline became transfusion independent, compared with 11% in the conventional care group.
Forty-six percent of patients in the azacitidine arm and 63% in the conventional care arm died.
Grade 3/4 hematologic toxicity (in the azacitidine and conventional care arms, respectively) included neutropenia (91% and 76%), thrombocytopenia (85% and 80%), and anemia (57% and 68%).
