The US Food and Drug Administration (FDA) has approved the use of ofatumumab (Arzerra®) in combination with fludarabine and cyclophosphamide to treat patients with relapsed chronic lymphocytic leukemia (CLL).

Ofatumumab was previously approved by the FDA for use in combination with chlorambucil to treat previously untreated CLL patients who cannot receive fludarabine-based therapy, as monotherapy for CLL that is refractory to fludarabine and alemtuzumab, and as maintenance therapy for patients who are in complete or partial response after receiving at least 2 lines of therapy for recurrent or progressive CLL.

Ofatumumab is a monoclonal antibody designed to target CD20.

The drug’s prescribing information includes a boxed warning noting that hepatitis B virus reactivation can occur in patients receiving CD20-directed cytolytic antibodies, including ofatumumab. In some cases, this results in fulminant hepatitis, hepatic failure, and death.

The boxed warning also states that progressive multifocal leukoencephalopathy, resulting in death, can occur in patients receiving CD20-directed cytolytic antibodies, including ofatumumab.

Ofatumumab is marketed under a collaboration agreement between Genmab and Novartis.

COMPLEMENT 2 trial

The FDA’s latest approval for ofatumumab is based on results of the phase 3 COMPLEMENT 2 trial. Novartis reported top-line results from this study in April.

The trial enrolled 365 patients with relapsed CLL. The patients were randomized 1:1 to receive up to 6 cycles of ofatumumab in combination with fludarabine and cyclophosphamide or up to 6 cycles of fludarabine and cyclophosphamide alone.

The primary endpoint was progression-free survival, as assessed by an independent review committee.

The median progression-free survival was 28.9 months for patients receiving ofatumumab plus fludarabine and cyclophosphamide, compared to 18.8 months for patients receiving fludarabine and cyclophosphamide alone (hazard ratio=0.67, P=0.0032).

Novartis said the safety profile observed in this study was consistent with other trials of ofatumumab, and no new safety signals were observed.

Study may explain why blood type affects cholera severity

Results of preclinical research may explain why people with blood type O often get more severely ill from cholera than people with other blood types.

The study suggests that, in people with blood type O, cholera toxin hyperactivates a key signaling molecule in intestinal cells.

And high levels of that molecule, cyclic adenosine monophosphate (cAMP), lead to excretion of electrolytes and water—in other words, diarrhea.

“We have shown that blood type influences how strongly cholera toxin activates intestinal cells, leading to diarrhea,” said study author James Fleckenstein, MD, of Washington University School of Medicine in Saint Louis, Missouri.

Dr Fleckenstein and his colleagues reported these findings in The American Journal of Tropical Medicine and Hygiene.

Cholera is caused by Vibrio cholerae, a bacterium that infects cells of the small intestine.

Epidemiologists first noticed 4 decades ago that people with blood type O were more likely to be hospitalized for cholera than people with other blood types, but the reasons for the difference had never been determined.

Although the blood group antigens—A, B, AB, and O—are best known for their presence on red blood cells, they also are found on the surface of many other cell types, including the cells that line the intestine.

To find out what effect cholera toxin has on intestinal cells carrying different blood group antigens, Dr Fleckenstein and his colleagues used clusters of intestinal epithelial stem cells, called enteroids, that can be grown in the lab and differentiated into mature intestinal cells.

The researchers treated 4 groups of enteroids with cholera toxin—2 derived from people with blood type A and 2 from people with blood type O—and measured the amount of cAMP inside the cells. Enteroids from the other 2 blood types—B and AB—were not available at the time the study was done.

The researchers found that levels of cAMP were roughly twice as high in the cells with the type O antigen than in the cells with type A antigen, suggesting that people with type O antigen who were exposed to cholera toxin would suffer more severe diarrhea.

“It is well-established that high levels of this molecule lead to diarrhea, so we’re making the assumption that higher levels lead to even more diarrhea,” said study author F. Matthew Kuhlmann, MD, of Washington University School of Medicine.

“Unfortunately, we have no way directly to link the responses to the volume of diarrhea and, therefore, the severity of disease.”

The researchers confirmed their enteroid results in an intestinal cell line originally derived from a person with blood type A. The cell line was modified to produce the type O antigen instead.

The team found that cholera toxin induced roughly double the amount of cAMP in cells with type O antigen than in those with type A.

Dr Fleckenstein said the researchers are not sure why cholera toxin induces different responses in cells with different blood group antigens on their surfaces.

“The cholera toxin is known to bind weakly to the ABO antigens, so they may be acting as decoys to draw the toxin away from its true target,” Dr Fleckenstein said. “It may be that the type O antigen just isn’t as good of a decoy as the type A antigen.”

Targeting Intracellular Pathways in Mesothelioma

Abstract 34: 2016 AVAHO Meeting

Purpose: The purpose of this study is to determine the efficacy of inhibition of mitochondrial antioxidant defense against mesothelioma and whether the cyclin-dependent kinase 4 (CDK4) inhibitor palbociclib sensitizes mesothelioma cells to inhibition of mitochondrial antioxidant defense.

Background: Mesothelioma is a highly fatal cancer with limited therapeutic options. Low expression of the endogenous CDK4 inhibitor p16INK4A has been demonstrated in up to 90% of mesothelioma tumors. CDK4 has also been demonstrated to activate manganese superoxide dismutase, which can decrease superoxide levels in cells and may make them less susceptible to induction of apoptosis. Downregulation of the key mitochondrial antioxidant protein, thioredoxin 2 (Trx2) has been demonstrated to increase reactive oxygen species production in mesothelioma cells resulting in reduced mesothelioma tumor growth. Gentian violet has been demonstrated to result in decreased expression of Trx2, a key mitochondrial antioxidant protein. The goal of this project is to determine whether concomitant targeting of the cell cycle and mitochondrial antioxidant pathways lead to improved efficacy against mesothelioma.

Methods: Mesothelioma cells were treated with compound or control and proliferation was evaluated using Cell Counting Kit 8 (Dojindo). For immunoblotting experiments, detection was performed using enhanced chemiluminescence. Apoptosis was detected via Cell Death Detection ELISAPLUS (Sigma-Aldrich). All experiments were done in duplicate or triplicate.

Data Analysis: IC50 curves were fitted via Origin software.

Results: Previously, we have demonstrated that palbociclib inhibits mesothelioma cell proliferation, inhibits retinoblastoma protein (Rb) phosphorylation, and results in cell cycle arrest. Mesothelioma cells in culture were treated with palbociclib and gentian violet alone and in combination. After 72h incubation with gentian violet, decreased cell proliferation was observed for 3 separate cell lines (IC50 = 365 nM, 870 nM, and 920 nM, respectively). Incubation with gentian violet for 24h resulted in decreased expression of Trx2 in all cell lines and also induced apoptosis in all cell lines. Gentian violetsensitized mesothelioma cells to palbociclib in a cell proliferation assay.

Implications: Gentian violet resulted in a significant decrease in mesothelioma cell proliferation. Palbociclib also sensitizes mesothelioma cells to gentian violet. Further investigation of this combination approach may demonstrate these combinations are useful for mesothelioma treatment.

Real-world study: 8 weeks of two-drug combo highly effective against HCV

Eight weeks of a two-drug combination led to sustained viral response (SVR) in 94% of noncirrhotic, treatment-naive, genotype 1 hepatitis C virus–infected patients, based on a retrospective study of Veterans Affairs health system data presented in the September issue of Gastroenterology.

But VA clinicians prescribed the 8-week regimen to less than half of eligible patients, said George Ioannou, MD, of the Veterans Affairs Puget Sound Health Care System in Seattle. Increasing its use, when appropriate, “could save on costs,” although the currently available interferon-free regimens “leave substantial room for improvement in SVRs among persons with cirrhosis and genotype 2 or 3 infections,” he and his associates wrote.

The two-drug regimen contained sofosbuvir and ledipasvir. Clinical trials of sofosbuvir, ledipasvir/sofosbuvir, and paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD) have reported SVR rates well above 90%, “with the exception of certain subgroups, such as patients with Child’s B or C cirrhosis and those infected with genotype 3 HCV,” the researchers noted. However, older interferon-based regimens did not perform as well in the real world as in trials, and “it is unclear if this is the case for current interferon-free regimens, or whether the relative ease of administration of these regimens has narrowed the SVR gap between clinical trials and clinical practice.” Questions also persist about how effective the interferon-free regimens are in various HCV genotypes and subgroups, they added (Gastroenterology 2016 Jul 18. doi: 10.1053/j.gastro.2016.05.049). To help answer these questions, they analyzed data from more than 17,000 HCV patients in the VA health care system who received sofosbuvir, ledipasvir/sofosbuvir, or paritaprevir/ritonavir/ombitasvir and dasabuvir between January 2014 and June 2015. The cohort included about 14,000 patients with genotype 1 infections, about 2,100 patients with genotype 2 infections, about 1,200 patients with genotype 3 infections, and 135 patients with genotype 4 infections. Patients averaged 62 years of age, about half were non-Hispanic white, 29% were non-Hispanic black, and nearly a third had been diagnosed with cirrhosis, including 10% with decompensated cirrhosis.

The VA guidelines recommended 8 weeks instead of 12 weeks of ledipasvir/sofosbuvir for treatment-naive, noncirrhotic, genotype 1 patients with a viral load under 6 million IU/mL, although that recommendation was not FDA approved and was based only on a post hoc analysis of the ION-3 trial, the investigators noted. These concerns seemed to affect practice – of 4,066 eligible patients, only 1,975 (49%) received the 8-week regimen. Notably, however, their rate of SVR 12 weeks after treatment (SVR12) was 95.1% (95% confidence interval, 94% to 96%) – nearly identical to that of patients with the same characteristics who received 12 weeks of treatment (95.8%; 94.7% to 96.8%; P = .6).

Rates of SVR12 did not significantly differ between ledipasvir/sofosbuvir and PrOD regimens, including in multivariable and propensity score–adjusted analyses, the researchers reported. Rates of SVR12 also exceeded 90% in subgroups of treatment-experienced and cirrhotic genotype 1 patients, they added. However, rates of SVR12 were lower for nongenotype 1 infections, as has been observed in trials. Specifically, rates of SVR12 were 90% for genotype 4 patients, 86% for genotype 2 patients who received sofosbuvir and ribavirin, and 75% for genotype 3 patients (including 78% for patients given ledipasvir/sofosbuvir plus ribavirin, 87% for patients given sofosbuvir and pegylated interferon plus ribavirin, and 71% for patients given sofosbuvir monotherapy). For cirrhotic patients, rates of SVR12 were 91% for genotype 1, 77% for genotype 2, 66% for genotype 3, and 84% for genotype 4.

The findings confirm that the new interferon-free regimens “can achieve remarkably high SVR rates in real-world clinical practice, especially in genotype 1–infected patients,” the researchers wrote. The cost of these regimens is “the main obstacle to curing HCV” in as many patients as possible, but is expected to “decline dramatically” as the FDA approves new regimens, they noted. “In fact, costs decreased dramatically within the VA after the completion of our study and after the FDA approved elbasvir/grazoprevir in January 2016.”

The study was funded by the Department of Veterans Affairs. The investigators had no disclosures.

The study was funded by the Department of Veterans Affairs. The investigators had no disclosures.

Eight weeks of a two-drug combination led to sustained viral response (SVR) in 94% of noncirrhotic, treatment-naive, genotype 1 hepatitis C virus–infected patients, based on a retrospective study of Veterans Affairs health system data presented in the September issue of Gastroenterology.

But VA clinicians prescribed the 8-week regimen to less than half of eligible patients, said George Ioannou, MD, of the Veterans Affairs Puget Sound Health Care System in Seattle. Increasing its use, when appropriate, “could save on costs,” although the currently available interferon-free regimens “leave substantial room for improvement in SVRs among persons with cirrhosis and genotype 2 or 3 infections,” he and his associates wrote.

The two-drug regimen contained sofosbuvir and ledipasvir. Clinical trials of sofosbuvir, ledipasvir/sofosbuvir, and paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD) have reported SVR rates well above 90%, “with the exception of certain subgroups, such as patients with Child’s B or C cirrhosis and those infected with genotype 3 HCV,” the researchers noted. However, older interferon-based regimens did not perform as well in the real world as in trials, and “it is unclear if this is the case for current interferon-free regimens, or whether the relative ease of administration of these regimens has narrowed the SVR gap between clinical trials and clinical practice.” Questions also persist about how effective the interferon-free regimens are in various HCV genotypes and subgroups, they added (Gastroenterology 2016 Jul 18. doi: 10.1053/j.gastro.2016.05.049). To help answer these questions, they analyzed data from more than 17,000 HCV patients in the VA health care system who received sofosbuvir, ledipasvir/sofosbuvir, or paritaprevir/ritonavir/ombitasvir and dasabuvir between January 2014 and June 2015. The cohort included about 14,000 patients with genotype 1 infections, about 2,100 patients with genotype 2 infections, about 1,200 patients with genotype 3 infections, and 135 patients with genotype 4 infections. Patients averaged 62 years of age, about half were non-Hispanic white, 29% were non-Hispanic black, and nearly a third had been diagnosed with cirrhosis, including 10% with decompensated cirrhosis.

The VA guidelines recommended 8 weeks instead of 12 weeks of ledipasvir/sofosbuvir for treatment-naive, noncirrhotic, genotype 1 patients with a viral load under 6 million IU/mL, although that recommendation was not FDA approved and was based only on a post hoc analysis of the ION-3 trial, the investigators noted. These concerns seemed to affect practice – of 4,066 eligible patients, only 1,975 (49%) received the 8-week regimen. Notably, however, their rate of SVR 12 weeks after treatment (SVR12) was 95.1% (95% confidence interval, 94% to 96%) – nearly identical to that of patients with the same characteristics who received 12 weeks of treatment (95.8%; 94.7% to 96.8%; P = .6).

Rates of SVR12 did not significantly differ between ledipasvir/sofosbuvir and PrOD regimens, including in multivariable and propensity score–adjusted analyses, the researchers reported. Rates of SVR12 also exceeded 90% in subgroups of treatment-experienced and cirrhotic genotype 1 patients, they added. However, rates of SVR12 were lower for nongenotype 1 infections, as has been observed in trials. Specifically, rates of SVR12 were 90% for genotype 4 patients, 86% for genotype 2 patients who received sofosbuvir and ribavirin, and 75% for genotype 3 patients (including 78% for patients given ledipasvir/sofosbuvir plus ribavirin, 87% for patients given sofosbuvir and pegylated interferon plus ribavirin, and 71% for patients given sofosbuvir monotherapy). For cirrhotic patients, rates of SVR12 were 91% for genotype 1, 77% for genotype 2, 66% for genotype 3, and 84% for genotype 4.

The findings confirm that the new interferon-free regimens “can achieve remarkably high SVR rates in real-world clinical practice, especially in genotype 1–infected patients,” the researchers wrote. The cost of these regimens is “the main obstacle to curing HCV” in as many patients as possible, but is expected to “decline dramatically” as the FDA approves new regimens, they noted. “In fact, costs decreased dramatically within the VA after the completion of our study and after the FDA approved elbasvir/grazoprevir in January 2016.”

Fecal immunochemical testing, colonoscopy outperformed multitarget stool DNA testing

Fecal immunochemical testing and colonoscopy detected colorectal cancer (CRC) more effectively and cheaply than did multitarget stool DNA testing, based on a Markov model that assumed equal rates of participation in the three strategies, according to a report in the September issue of Gastroenterology.

Multitarget stool DNA testing (MT-sDNA) “may be a cost-effective alternative if it can achieve patient participation rates that are high enough compared with those of FIT [fecal immunochemical testing] that paying for its higher test cost can be justified,” wrote Uri Ladabaum, MD, and Ajitha Mannalithara, PhD, of Stanford (Calif.) University.

Studies have yielded mixed results about whether FIT or fecal DNA testing are preferable for CRC detection. In one recent large prospective study of patients at average CRC risk, a MT-sDNA test that included KRAS mutations, aberrant NDRG4 and BMP3 methylation, and hemoglobin outperformed FIT for detecting CRC and precancerous lesions but also yielded more false positives, the researchers noted.

Although many decision analyses have examined the efficacy and cost of CRC screening strategies, they have not delved into “the complex patterns of screening participation over time that are now being described (consistent screeners, late entrants, dropouts, intermittent screeners, consistent non-responders),” accounted for variable participation in organized and opportunistic screening programs, or controlled for differential reimbursement rates for public versus private insurance, they added (Gastroenterology 2016 Jun 7. doi: 10.1053/j.gastro.2016.06.003).

Dr. Ladabaum and Dr. Mannalithara therefore constructed a Markov model of patients at average risk for CRC to compare the efficacy and costs of MT-sDNA, colonoscopy, and FIT. The model included numerous variables, such as disease states ranging from a small adenomatous polyp to disseminated CRC, longitudinal changes in rates of participation for both opportunistic screening and organized screening programs, and different rates of commercial and Medicare reimbursement.

Assuming optimal adherence, an annual FIT test and colonoscopy every 10 years were more effective and less costly than MT-sDNA every 3 years, the researchers found. Compared with successful FIT screening programs – which have a 50% rate of consistent participation and a 27% rate of intermittent participation and cost about $153 per patient per testing cycle – an MT-sDNA program would need to have at least a 68% rate of consistent participation and a 32% rate of intermittent (every 3 years) participation, or would need to cost 60% less than it does now ($260 for commercial payment and $197 for Medicare payment in 2015) to be preferable when assuming a threshold of $100,000 for every extra quality-adjusted life year (QALY) gained. MT-sDNA every 3 years, however, would be more cost-effective than opportunistic FIT screening if participation rates were more than 1.7 times those that are typical of opportunistic FIT (15% consistent participation and 30% intermittent participation).

These results held up in various subgroup analyses, and FIT was preferred in 99% of iterations in a Monte Carlo simulation that assumed equal participation rates and the same $100,000 per QALY threshold. “For the MT-sDNA test to be cost-effective, the patient support program included in its cost would need to achieve substantially higher participation rates than those of FIT, whether in organized programs or under the opportunistic screening setting more common in the U.S. than in the rest of the world,” they concluded.

The study was funded by an unrestricted research grant from Exact Science Corp. Dr. Ladabaum reported consulting for ESC in 2014 and disclosed current consulting or advisory relationships with Given Imaging and Mauna Kea Technologies. Dr. Mannalithara had no disclosures.

Study reinforced value of preconception IBD care

Targeted and regular outpatient care before conception helped prevent relapse of inflammatory bowel disease (IBD) during pregnancy, according to a single-center prospective observational study reported in the September issue of Clinical Gastroenterology and Hepatology.

Women who received such care had about 50% lower odds of relapse while pregnant compared with women seen only after conception, said Alison de Lima, MD, PhD, of Erasmus MC–University Medical Hospital Rotterdam (the Netherlands) and her associates. “Preconception care seems effective in achieving desirable behavioral modifications in IBD women in terms of folic acid intake, smoking cessation, and correct IBD medication adherence, eventually reducing disease relapse during pregnancy. Most importantly, preconception care positively influences birth outcomes,” the investigators concluded.

Several recent studies have reported “incorrect beliefs, unfounded fears, and insufficient knowledge” among women with IBD when it comes to pregnancy, the researchers noted. These beliefs can undermine medication adherence, potentially increasing the risk of complications and poor birth outcomes, they added. Studies have confirmed the value of preconception care for chronic diseases such as diabetes, but none had done so for IBD (Clin Gastroenterol Hepatol. 2016 Mar 18. doi: 10.1016/j.cgh.2016.03.018). Therefore, Dr. de Lima and her associates prospectively followed 317 women seen at the IBD preconception outpatient clinic at a tertiary referral hospital during 2008-2014. A total of 155 patients first visited the clinic before becoming pregnant, while the other 162 patients did so only after conception. New patient visits lasted about 30-45 minutes and included fecal calprotectin testing to assess disease activity, education about the need to avoid conceiving during a disease flare, and general advice about taking folic acid, quitting smoking, and avoiding alcohol during pregnancy. Follow-up visits, which occurred every 3 months before pregnancy and every 2 months thereafter, included clinical assessments of disease activity, maternal serum testing to assess compliance with antitumor necrosis factor and thiopurine therapy, and assessments of folic acid supplementation, smoking, and alcohol use.

Patients who received such care before conceiving tended to be younger (29.7 vs. 31.4 years; P = .001), were more often nulliparous (76% vs. 51%; P = .0001), and had a shorter history of IBD (5.1 vs. 8 years; P = .0001), compared with the postconception care group, the researchers said. However, after researchers controlled for parity, disease duration, and the number of relapses in the year before pregnancy, the preconception care group had a nearly sixfold greater odds of adhering to IBD medications during pregnancy (adjusted odds ratio, 5.7; 95% confidence interval, 1.9-17.3), about a fivefold greater odds of sufficient folic acid intake (aOR, 5.3; 95% CI, 2.7-10.3), and a more than fourfold odds of smoking cessation during pregnancy (aOR, 4.63; 95% CI, 1.2-17.6). Notably, preconception care was tied to a 49% lower odds of disease relapse during pregnancy (aOR, 0.51; 95% CI; 0.28-0.95) and to a nearly 50% lower rate of low birth weight (birth weight less than 2,500 g).

“To our surprise, this study did not detect an effect of preconception care on periconceptional disease activity,” the researchers said – even though they strove to educate patients on this concept. “We can only speculate about the explanation for this finding, but we believe this could be a result of a discrepancy between physician-declared disease remission and the patient’s own feeling of well-being combined with a strong reproductive desire.”

The investigators reported no funding sources, and Dr. de Lima had no disclosures. Two coinvestigators reported ties to Merck Sharp & Dohme, Abbott, Shire, and Ferring.

‘Enough!’ We need to take back our profession; More unresolved questions about psychiatry

‘Enough!’ We need to take back our profession

Every day, I am grateful that I became a physician and a psychiatrist. Every minute that I spend with patients is an honor and a privilege. I have never forgotten that. But it is heartbreaking to see my precious profession being destroyed by bureaucrats.

An example: I am concerned about the effect that passage of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) will have on physicians. I read articles telling us how we should handle this new plan for reimbursement, but I also read that 86% of physicians are not in favor of MACRA. How did we get stuck with it?

Another example of why it has become virtually impossible to do our job: I spend a fair amount of time obtaining prior authorization for generic medications that are available at big-box stores for $10 or $15; often, these authorizations need approval by the medical director. I have been beaten down enough over the years to learn that I should no longer prescribe brand-name medications—only generic medications (which still require authorization!), even when my patient has been taking the medication for 10 or 15 years. The last time I sought authorization to prescribe a medication, the reviewer asked me why I had not tried 3 different generics over the past year. I had to remind her that I had an active prior authorization in place from the year before, and so why would I do what she was proposing?

Physicians are some of the most highly trained professionals. It takes 7 to 15 years to be able to be somewhat proficient at the job, then another 30 or 40 years of practice to become really good at it. But we’ve become technicians at the mercy of business executives: We go to our office and spend our time checking off boxes, trying to figure out proper coding and the proper diagnosis, so that we can get an appropriate amount of money for the service we’re providing. How has it come to this? Why can’t we take back our profession?

Another problem is that physicians are being paid for their performance and the outcomes they produce. But people are not refrigerators: We can do everything right and the patient still dies. I have a number of patients who have no insight into their psychiatric illness; no matter what I say, or do, or how much time I spend with them, they are nonadherent. How is this my fault?

Physicians are not given the opportunity to think for themselves, or to prescribe treatments that they see fit and document in ways that they were trained. Where is the American Medical Association, the Connecticut State Medical Society, the Hartford County Medical Association, and all the other associations that supposedly represent us? How have they allowed this to happen?

In the future, health care will be provided by physician assistants and nurse practitioners; physicians will provide background supervision, or perform surgery, but the patient will never meet them. I respect NPs and PAs, but they do not have the rigorous training that physicians have. But they’re less expensive—and isn’t that what it’s all about?

If we are not going to speak up, or if we are not going to elect officials to truly represent us and advocate for us, then we have nobody to blame but ourselves.

More unresolved questions about psychiatry

In Dr. Nasrallah’s August essay (From the Editor, Current Psychiatry. "Unresolved questions about the specialty lurk in the cortex of psychiatrists," p. 10,11,19,19A), he asks, as he often does, provocative, unanswered questions. There are probably many more questions to include in his list, but I’ll just add 1—the one that I think is the biggest problem in our field: Why is the burnout rate of physicians steadily climbing, to the extent that it exceeds the epidemic rate of 50%? Although you would think that we, as psychiatrists, should be expert at understanding and addressing this problem, our own burnout rate is >40%. Moreover, why haven’t we developed programs to prevent and reduce burnout, when other specialties, such as urology and emergency medicine, have done so?

Dr. Nasrallah responds

Dr. Moffic is spot-on about the escalating rate of burnout among physicians, including psychiatrists. The reason I did not include burnout in the list of questions is because I intended to pose questions related to external forces that interfere with patient care. Burnout is a vicious internal typhoon of emotional turmoil that might be related to multiple idiosyncratic personal variables and only partially to frustrations in clinical practice.

 

 

Burnout is, one might say, a subcortical event (generated in the amygdala?)—not a cortical process like the “why” questions that beg for answers. Admittedly, however, the cumulative burden of practice frustrations—especially the inability to erase the personal, social, financial, and vocational stigmata that plague our patients’ lives—can, eventually, take a toll on our morale and quality of life.

Fortunately, we psychiatrists generally are a resilient breed. We can manage personal stress using techniques that we employ in our practices. That might be why burnout is lower in psychiatry than it is in other medical specialties.
