MEK plus BRAF inhibitor reduces SCC risk in melanoma

Adding a MEK inhibitor to BRAF inhibitor treatment for metastatic melanoma is associated with a significant reduction in the risk of cutaneous squamous cell carcinoma and other cutaneous toxic effects, new data suggests.

A retrospective cohort study in 185 patients with unresectable stage IIIC and IV melanoma showed those treated with BRAF inhibitors dabrafenib or vemurafenib in combination with a MEK inhibitor had zero cases of cutaneous squamous cell carcinoma, verrucal keratosis or Grover disease but a 40% incidence of folliculitis, according to a paper published online July 22 in JAMA Dermatology.

In contrast, the rates of cutaneous squamous cell carcinoma were significantly higher among patients treated with either dabrafenib or vemurafenib alone (26.1% and 36.1%, respectively), as was the incidence of Grover disease (42.9% and 38.9%) and verrucal keratosis (66.4% and 72.2%).

“Recognition of the variety of cutaneous toxic effects associated with these different therapies, including the predisposing risk factors for their development, is important with the purpose of ensuring appropriate rapid intervention and thereby abrogating the need to delay or even withhold these essential treatments,” wrote Dr. Giuliana Carlos of Westmead Hospital, Sydney, and coauthors (JAMA Dermatology 2015, July 22 [doi:10.1001/jamadermatol.2015.1745]).

The study was supported by the Westmead Medical Research Foundation. Three authors reported travel support or consultancies with pharmaceutical companies, but there were no other conflicts of interest declared.

Daclatasvir plus sofosbuvir safe and effective in HCV/HIV coinfection

Patients treated with daclatasvir and sofosbuvir for hepatitis C who are coinfected with HIV have shown a significant virologic response, regardless of whether they had already been treated for their hepatitis C infection, according to data presented at the International AIDS Society Conference on HIV Pathogenesis, Treatment & Prevention.

The open-label ALLY-2 study – published simultaneously in the July 21 online edition of the New England Journal of Medicine – in 151 previously untreated patients with hepatitis C and HIV, and 52 previously treated patients, showed 12 weeks of treatment with NS5A inhibitor daclatasvir and sofosbuvir achieved a sustained virologic response in 96.4% of untreated patients and 97.7% of previously treated patients with HCV genotype 1, with no adverse effects on HIV-1 suppression.

Among previously untreated patients treated for 8 weeks, the response rate was 75.6%, and there were no study-drug discontinuations because of adverse events (N. Engl. J. Med. 2015 July 21 [doi:10.1056/NEJMoa1503153]).

“The lower efficacy observed after 8 weeks of treatment suggests that 12 weeks of therapy may be preferred for most patients with HIV-HCV coinfection,” wrote Dr. David L. Wyles of the University of California, San Diego, and his coauthors.

Bristol-Myers Squibb supported the study. Dr. Wyles reported serving as a scientific consultant to Bristol-Myers Squibb and Gilead Sciences. Some coauthors declared grants, personal fees, and speakers fees from pharmaceutical companies, including Bristol-Myers Squibb, and several authors are employees of Bristol-Myers Squibb.

Ledipasvir plus sofosbuvir achieve excellent response in HCV/HIV coinfection

Treatment with ledipasvir and sofosbuvir achieves sustained virologic response at 12 weeks in patients with hepatitis C who also are infected with HIV, according to the results of the open-label ION-4 study presented at the International AIDS Society Conference on HIV Pathogenesis and Treatment.

The multicenter study in 335 patients – published simultaneously online July 21 by the New England Journal of Medicine – showed, overall, that 96% of patients had a sustained virologic response 12 weeks after the end of therapy, while the response rates were higher (100%) among individuals with HCV genotype 4 but lower in black patients.

“This association between black race and a decreased rate of virologic response was not observed in the 308 black patients who were monoinfected with HCV receiving ledipasvir-sofosbuvir across the phase III program,” wrote Dr. Susanna Naggie of the Duke Clinical Research Institute, Durham, N.C., and her coauthors.

Response rates were not influenced by previous treatments or the presence of cirrhosis, and while there were some adverse events such as headache, fatigue, and diarrhea, no patient had confirmed HIV-1 virologic rebound (N. Engl. J. Med. 2015 July 21 [doi:10.1056/NEJMoa1501315]).

Childhood psychiatric illness tied to adult psychopathology

Childhood psychiatric illness tied to adult psychopathology

Childhood psychiatric disorders are associated with significant increases in the risk of adverse outcomes in adulthood, including dropping out of high school, addiction, suicidality, serious criminal activity, and housing problems, even after accounting for childhood hardship and adult psychiatric problems.

A prospective, population-based cohort study of 1,420 individuals aged 9-16 at enrollment showed those diagnosed with childhood psychiatric disorders, such as childhood depression or conduct disorder, were six times more likely to develop at least one adverse adult outcome, and nine times more likely to develop more than one, compared with those with no history of psychiatric illness.

Individuals without a diagnosis who had subthreshold psychiatric problems had a threefold increase in the risk of later problems, according to a study published online July 15 in JAMA Psychiatry.

“Our study suggests that recognizing subthreshold cases needs to be a public health priority and that intervention for these individuals may forestall future impairments, distress, and societal costs,” wrote William E. Copeland, Ph.D., of Duke University, Durham, N.C., and his coauthors (JAMA Psychiatry 2015 July 15 [doi:10.1001/jamapsychiatry.2015.0730]).

Several possible explanations might explain the causal links between childhood psychopathology and adult psychopathology. Children who experience mental health problems such as conduct disorder might alienate supportive family members and peers, which in turn, might “lead to curtailed education and incarceration, and increase the risk of brain and spinal cord injuries.” In addition, childhood and adult psychopathology might be influenced by some of the “same genetic and environmental factors.” Finally, certain external conditions exist for children and persist into adulthood that might lead to psychopathology. “For example, psychopathology at all ages may be fostered by chronic economic instability, pollution, living in disorganized and violent neighborhoods, and lack of stable social support.”

Unfortunately, there is little empirical data yet to choose between these explanations, and studies of the predictive association between childhood psychopathologies and adulthood psychopathologies raise more questions than they answer.

Rare mutation identified in fatal enteropathy

Whole exome sequencing of an infant who died at 5 months of severe protein-losing enteropathy has revealed a rare mutation in the plasmalemma vesicle–associated protein gene.

The infant, who was from consanguineous parents, presented at 8 days of age with secretory diarrhea, metabolic acidosis, lethargy, poor feeding, and severe hyponatremia causing seizures, then developed hematochezia a day later.

Laboratory tests showed undetectable albumin that did not respond to repeated infusions, but there was no evidence of proteinuria, according to a report published in the July issue of Cellular and Molecular Gastroenterology and Hepatology (doi:10.1016/j.jcmgh.2015.05.001).

“Over the next 2 months of life, he developed enteroviral and rhinoviral upper respiratory tract infections,” wrote Dr. Abdul Elkadri of the Hospital for Sick Children, Toronto, and colleagues.

“He persistently had severe anasarca and was found to have venous thrombosis in multiple locations.”

At 5 months, the infant developed sepsis, which resulted in multiorgan failure and death.

Researchers performed whole exome sequencing on samples obtained on two separate occasions during endoscopic investigation for severe protein-losing enteropathy, and used samples from patients with gastrointestinal symptoms but normal endoscopy and histology as controls.

Sequencing identified a homozygous nonsense mutation (1072C>T; p.Arg358*) in the plasmalemma vesicle–associated protein gene (PLVAP); an extremely rare mutation that has been identified only in one heterozygote individual from more than 121,000 sequenced.

“PLVAP is a cationic, integral membrane glycoprotein that is specifically expressed in endothelial cells,” the authors wrote.

“PLVAP forms homodimers and plays a critical role in the formation of the diaphragms of caveolae and fenestrae/transendothelial channels [and] PLVAP positive diaphragms of fenestrated capillaries are essential for the maintenance of blood composition.”

When the researchers examined the patient’s biopsies under electron microscope, they found a complete absence of the fenestrae and caveolae of endothelial cells of all the capillaries in the duodenum villi examined.

They also observed tissue edema, endothelial thickening, and extracellular lipid deposition that were previously reported in PLVAP knockout mice.

“These data suggested that the truncated mutant PLVAP was either not expressed or was incapable of forming diaphragms.”

The authors said this was the first human PLVAP mutation resulting in severe, fatal sieving hypoproteinemia and enteropathy.

“Deletion of fenestral diaphragms causes leakage of plasma proteins into the interstitium of organs provided with fenestrated capillaries (intestine, pancreas, adrenals) and from there into the peritoneal cavity and into the intestine lumen, but not in organs with continuous endothelium (heart, muscle, lung),” they wrote.

The patient also had severely depleted plasma proteins, which the authors suggested occurred because of the loss of fenestral diaphragms in the intestine.

Two broad categories of protein-losing enteropathies have previously been described – the mucosal injury observed with inflammatory bowel disease, and abnormalities of the lymphatic system observed in primary intestinal lymphangiectasia.

However, there has been growing interest in possible genetic causes of these severe intestinal conditions, and causative genetic defects have yet to be identified in many infants with severe intestinal disease, including protein-losing enteropathy.

“Further work in animals modeling the human PLVAP mutation should shed light on the molecular mechanism of PLVAP downregulation, as well as the molecular mechanisms resulting in epithelial barrier disruption prompting interventional strategies.”

No relevant conflicts of interest were declared.

Protein-losing enteropathy (PLE) features excessive serum protein loss into the gastrointestinal tract, often eliciting severe hypoproteinemia, edema, ascites, malnutrition, and fatality in affected infants. This rare clinical syndrome is thought to contribute to several erosive or nonerosive GI pathologies, such as the inflammatory bowel diseases; however, its genetic and molecular pathogenesis has not been explored in detail. From an infant who died from a severe PLE, Elkadri et al. isolated a homozygous nonsense mutation in a gene named plasmalemma vesicle–associated protein (PLVAP). This single nucleotide mutation (1072C>T) prematurely truncates PLVAP protein into an unstable form that cannot contribute to proper formation of diaphragms in the fenestrae – small pores in endothelial cells used for rapid exchange of molecules between fenestrated blood vessels.

Interestingly, this primary pathological defect was found in the patient’s intestinal vascular endothelial cells, rather than intestinal epithelial cells that are often affected in some well-known forms of congenital enteropathy, e.g., microvillus inclusion disease or congenital tufting enteropathy. The histopathological features of endothelium in this PLVAP p.R358 patient resembled those of PLVAP knockout mice at ultrastructural and biochemical levels. With genome sequencing, it becomes plausible to screen infants for this genetic mutation and prevent severe complications at an early disease stage. Studies extrapolating genetic causes of rare GI and hepatic disorders are much needed, as we move into the era of precision medicine, to effectively identify and guide treatment of these patients.

Mixed results for fecal transplants in ulcerative colitis

Two studies of using fecal microbiota transplants to treat ulcerative colitis have had mixed results.

Researchers conducted a double-blind parallel study of 75 individuals with active ulcerative colitis; 38 received fecal microbiota transplants from healthy anonymous donors, and 37 received a placebo dose of water, once a week for 6 weeks.

While the trial was terminated early for reasons of futility, among the patients who completed treatment, the authors observed a 7-week remission rate of 24% among the patients who received the fecal transplants, compared with a 5% remission rate in the placebo group – a statistically significant difference – according to the study published in the July issue of Gastroenterology (doi:10.1053/j.gastro.2015.04.001).

“The benefit was relatively modest, but our endpoint for treatment success was more stringent than most trials in UC and remission rates seen with FMT [fecal microbiota transplants] were consistent with a similar endpoint for a novel biologic therapy,” wrote Dr. Paul Moayyedi of the Farncombe Family Digestive Health Research Institute, Ontario, and coauthors.

Seven of the nine patients who achieved remission – defined as a Mayo score ≤ 2 with an endoscopic Mayo score of 0 – after the fecal microbiota transplants were all treated with transplants from a single donor. “The efficacy of this approach may also be donor dependent and this may explain why some case series have shown promise, and others have had disappointing results,” the authors wrote.

Those who had ulcerative colitis for less than a year had a significantly higher rate of remission than those who had the disease for more than a year, while patients who received the transplants showed a greater microbial diversity in their stool, compared with their baseline, than did the patients in the control group.

A second study found no significant different in remission rates between patients who received donor fecal microbiota transplants and a control group who received autologous transplants.

In the double-blind randomized trial, 50 patients with moderately active ulcerative colitis were administered two transplants via nasoduodenal tube, 3 weeks apart, according to a paper published online March 30 in Gastroenterology.

Among the 37 patients who completed the study, 30.4% of those who received transplants from donors and 20% of controls met the primary endpoint of clinical remission (P = 0.51), according to the intention-to-treat analysis (Gastroenterology 2015 March 30 [doi:10.1053/j.gastro.2015.03.045]).

In the per-protocol analysis, the difference between the active and control group was slightly greater but still failed to reach statistical significance.

The authors suggested that low numbers may have contributed to the lack of effect of the donor fecal transplants, However the study did find that at 12 weeks, those who had received the donor fecal microbiota and responded to it had a microbiota similar to that of their healthy donors.

“Therefore we may assume that even though both treatment groups included responders, the subsequent effects on microbiota composition are different in the FMT-D (donor) and FMT-A (autologous) groups,” wrote Dr. Noortje G. Rossen of the Academic Medical Center, Amsterdam, and coauthors.

The first study was funded by Hamilton Academic Health Sciences Organization, and Crohn’s and Colitis Canada. Some authors declared honoraria, speaking engagements, advisory board positions, consultancies and research funding from a range of pharmaceutical companies.

The second study was supported by MLDS and NWO-Spinoza, and there were no conflicts of interest declared.

Researchers conducted a double-blind parallel study of 75 individuals with active ulcerative colitis; 38 received fecal microbiota transplants from healthy anonymous donors, and 37 received a placebo dose of water, once a week for 6 weeks.

While the trial was terminated early for reasons of futility, among the patients who completed treatment, the authors observed a 7-week remission rate of 24% among the patients who received the fecal transplants, compared with a 5% remission rate in the placebo group – a statistically significant difference – according to the study published in the July issue of Gastroenterology (doi:10.1053/j.gastro.2015.04.001).

“The benefit was relatively modest, but our endpoint for treatment success was more stringent than most trials in UC and remission rates seen with FMT [fecal microbiota transplants] were consistent with a similar endpoint for a novel biologic therapy,” wrote Dr. Paul Moayyedi of the Farncombe Family Digestive Health Research Institute, Ontario, and coauthors.

Seven of the nine patients who achieved remission – defined as a Mayo score ≤ 2 with an endoscopic Mayo score of 0 – after the fecal microbiota transplants were all treated with transplants from a single donor. “The efficacy of this approach may also be donor dependent and this may explain why some case series have shown promise, and others have had disappointing results,” the authors wrote.

Those who had ulcerative colitis for less than a year had a significantly higher rate of remission than those who had the disease for more than a year, while patients who received the transplants showed a greater microbial diversity in their stool, compared with their baseline, than did the patients in the control group.

A second study found no significant different in remission rates between patients who received donor fecal microbiota transplants and a control group who received autologous transplants.

In the double-blind randomized trial, 50 patients with moderately active ulcerative colitis were administered two transplants via nasoduodenal tube, 3 weeks apart, according to a paper published online March 30 in Gastroenterology.

Among the 37 patients who completed the study, 30.4% of those who received transplants from donors and 20% of controls met the primary endpoint of clinical remission (P = 0.51), according to the intention-to-treat analysis (Gastroenterology 2015 March 30 [doi:10.1053/j.gastro.2015.03.045]).

In the per-protocol analysis, the difference between the active and control group was slightly greater but still failed to reach statistical significance.

The authors suggested that low numbers may have contributed to the lack of effect of the donor fecal transplants, However the study did find that at 12 weeks, those who had received the donor fecal microbiota and responded to it had a microbiota similar to that of their healthy donors.

“Therefore we may assume that even though both treatment groups included responders, the subsequent effects on microbiota composition are different in the FMT-D (donor) and FMT-A (autologous) groups,” wrote Dr. Noortje G. Rossen of the Academic Medical Center, Amsterdam, and coauthors.

The first study was funded by Hamilton Academic Health Sciences Organization, and Crohn’s and Colitis Canada. Some authors declared honoraria, speaking engagements, advisory board positions, consultancies and research funding from a range of pharmaceutical companies.

The second study was supported by MLDS and NWO-Spinoza, and there were no conflicts of interest declared.

Though it has not yet been established whether dysbiosis is a cause or consequence of inflammation in inflammatory bowel disease, excitement among patients and clinicians around fecal microbiota transplantation in IBD has grown rapidly. Online success stories tout the “Power of Poop,” and patients don’t even need to wait for a new drug to come down the pipeline. For those ready to pursue FMT without hard efficacy and safety data, there are DIY guidebooks, YouTube videos, and websites to help them find donors.

Both of these studies were underpowered, but they represent an improvement compared with previous case series and cohort studies, which were limited by small numbers of patients, open-label design, vague FMT protocols, incomplete reporting of IBD-specific data, and poorly defined outcomes. Neither showed FMT to be overwhelmingly beneficial, though there may have been signals of benefit in some subjects, in whom microbiome engraftment led to clinical remission and endoscopic response. Why was one study positive and the other negative, despite enrolling a similar patient population? Perhaps a lower GI route of administration and a more intensive dosing regimen are required to effectively alter the distal gut microbiome. Alternatively, there may be an optimal donor microbial profile. Anti-TNF agents may have impacted response through immunologic factors. Or were Moayeddi’s results only a statistical anomaly, driven by the unusually low 5% response in the placebo group?

What is clear is that these two studies are not game-changers. We have been manipulating the microbiome in IBD with antibiotics and probiotics for decades. Microbiota-based therapies may prove to be beneficial in some patients, but IBD is heterogeneous. If FMT can make some better, can it make others worse? Larger clinical trials to establish both efficacy and safety are critical before FMT can be considered ready for prime time.

Older MI patients missing out on ICDs

Fewer than one in 10 elderly patients with a low ejection fraction after myocardial infarction who are eligible to receive an implantable cardioverter-defibrillator actually receive one within a year of their myocardial infarction, a study has found.

The retrospective observational study of 10,318 patients aged over 65 years who had experienced a myocardial infarction and had an ejection fraction of 35% or less showed only 8.1% received an implantable cardioverter-defibrillator (ICD) within a year of their MI, even though implantation within a year was associated with a 36% reduction in mortality at 2 years.

Those patients who did receive an ICD were more likely to have had a prior coronary artery bypass graft, had higher peak troponin levels, experienced in-hospital cardiogenic shock, or had a cardiology follow-up within 2 weeks of discharge, according to the paper published June 23 in JAMA.

“Individualized shared decision making, taking into context the patient’s quality of life, treatment goals, and preferences, is critical, because ICD therapy may shift death from a sudden event to a more gradual comorbid process,” wrote Dr. Sean D. Pokorney, of Duke University Medical Center, Durham, N.C., and co-authors (JAMA 2015;313:2433-40 [doi: 10.1001/jama.2015.6409]).

The study was supported by the Agency for Healthcare Research& Quality, and Boston Scientific. Some authors declared research grants, honoraria, advisory board positions, and consultancies with private industry.

It is concerning that so few potentially ICD-eligible elderly patients are undergoing implantation, especially considering that ICDs significantly improve survival.

A possible scenario is that many of these patients did not receive an appropriate ICD simply because they fell into a crevasse of the fragmented health system in which overly burdened primary care physicians are expected to connect all the clinical and diagnostic information without the essential tools and necessary facts.
