Treatment failure and the adverse effects of traditional psoriasis medications increasingly are driving patients to complementary and alternative medicines (CAMs), despite limited documentation supporting their efficacy, reported Emily C. Murphy and her associates, in the department of dermatology, George Washington University, Washington.

They performed a survey-based statistical analysis to identify specific types of commonly used CAMs, and to explore reasons patients increasingly turn to alternative therapies. The survey was distributed in the National Psoriasis Foundation’s (NPF) October 2018 newsletter to its 100,927 members. Their results were published in a letter to the editor of the Journal of the American Academy of Dermatology.

Of the 6,101 NPF members who opened the newsletter, 324 clicked on the survey link. Of the 219 who completed the survey, almost 70% were women. The majority were white (84.1%), compared with Hispanic (6.2%), Asian (3.1%), and black (2.6%) participants. Most of the survey respondents had a dermatologist diagnosis of psoriasis, as well as access to health insurance to cover any prescribed medicines needed.

Of the 41% of respondents who reported using alternative therapies, usage was especially high among those who considered their psoriasis as severe (50% vs. 33.6% of those with nonsevere disease). Among the respondents, women were more likely than were men to use CAMs (45.6% vs. 26.5%, P = .002).

Only 4% cited access to care as a reason for choosing alternative therapies; the majority said they used CAMs because “traditional medications did not help or had side effects.”

While men were more likely than were women to use vitamins (24% vs. 18.9%, respectively), Dead Sea bath salts (17% vs. 7.8%), and cupping (3% vs. 0.8%), women were more likely to use herbals/botanicals (17% vs. 14%) and yoga (9.6% vs. 2%).

Patients with moderate psoriasis were significantly more likely than were those with mild or severe cases of the disease to recommend CAMs, regardless of insurance status (52.4% vs. 35% among those with mild disease and 40.4% for those with severe disease).

For some of the commonly used treatments, such as vitamins D and B₁₂, there is insufficient evidence documenting their efficacy, although Dead Sea treatments have been shown to have therapeutic effects. And while there is efficacy evidence for indigo naturalis and meditation, these were not mentioned or were not commonly reported by respondents, the authors pointed out.

Although just 43% of patients said they would recommend a CAM to other people with psoriasis, its use remains widespread. For this reason, “educational initiatives that enable physicians to discuss evidence-based CAMs may improve patient satisfaction and outcomes,” observed Ms. Murphy, a research fellow, and her associates.

Previous studies have cited rates of CAM usage among patients with psoriasis as high as 62%, but researchers have failed to examine the reasons motivating usage. Not surprisingly, patients often use but misunderstand the benefits of alternative therapies.

“The onus is on us as physicians to not only ask our patients if they are using nonallopathic therapies for their psoriasis, but also to create an accepting environment that enables further discussion regarding said treatments to ensure patient safety and ultimately good outcomes,” senior author Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, said in an interview.

The authors had no financial sources or conflicts of interest to disclose; there was no funding source.

The Diagnosis: Lichen Nitidus 

Our patient represents a case of lichen nitidus (LN) that was diagnosed through clinicopathologic correlation, with the pathology results showing a lymphohistiocytic infiltrate in the papillary dermis enclosed by acanthotic rete ridges on either side. Lichen nitidus was first described by Pinkus in 1901 as a variant of lichen planus.¹ It is a rare chronic inflammatory disease that is most prevalent in children and adolescents.² Clinically, the lesions appear as 1- to 2-mm, shiny, flesh-colored papules with central umbilication.³ Typically, lesions are localized and discrete; however, vesicular, hemorrhagic, perforating, spinous follicular, linear, generalized, and actinic variants all have been reported in the literature. Lichen nitidus has a predilection for the lower abdomen, medial thighs, penis, forearms, ventral wrists, and hands.⁴ Cases of LN have been reported on the palms, soles, nails, and mucosa, presenting a diagnostic challenge.⁵ The pathogenesis of LN is unknown, and all races and sexes are affected equally.⁶  

Histopathologically, LN has distinct findings including a well-circumscribed lymphohistiocytic infiltrate in the papillary dermis embraced by elongated and acanthotic rete ridges.² These histopathologic characteristics were seen in our patient's biopsy specimen (Figure) and have been described as the ball-and-claw configuration. Lichen nitidus may be pruritic but typically is asymptomatic.⁷ It often spontaneously regresses within months to years without any treatment⁷; however, successful outcomes have been seen with topical steroids, UVA/UVB phototherapy, and retinoids.² Our patient was treated with topical steroids. 

The differential diagnosis for LN includes verruca plana, dyshidrotic eczema, acral persistent papular mucinosis (APPM), and molluscum contagiosum. Verruca plana can occur as 1- to 5-mm, grouped, flesh-colored papules on the face, neck, dorsal hands, wrists, or knees.⁸ Most commonly, verruca plana occurs due to human papillomavirus type 3 and less commonly human papillomavirus types 10, 27, and 41. Verruca plana is easily differentiated from LN on pathology with findings of epidermal hyperkeratosis, irregular acanthosis, and koilocytic changes.⁸  

Dyshidrotic eczema is a pruritic vesicular rash that is classically distributed symmetrically on the palmar aspects of the hands and lateral fingers.⁹ Histopathology of the lesions reveals spongiosis with an epidermal lymphocytic infiltrate. Exacerbating factors include exposure to allergens, stress, fungal infections, and genetic predisposition.⁹ 

Acral persistent papular mucinosis can present as multiple, 2- to 5-mm, flesh-colored papules on the dorsal aspects of the hands.¹⁰ However, the demographic is different from LN, as APPM most commonly affects middle-aged females versus adolescents. Lesions of APPM may multiply or spontaneously remit over time. Acral persistent papular mucinosis generally is asymptomatic but can be treated with cryotherapy, topical corticosteroids, electrodesiccation, or CO₂ lasers for cosmetic purposes. Acral persistent papular mucinosis can be easily distinguished from LN on histology, as it will show areas of focal, well-circumscribed mucin in the papillary dermis and a spared Grenz zone.¹⁰ 

Molluscum contagiosum is a common viral skin infection caused by the poxvirus that affects children and adults.¹¹ The skin lesions appear as 2- to 4-mm, dome-shaped, flesh-colored papules with central umbilication on the limbs, trunk, or face. Clinicians may choose to monitor lesions of molluscum contagiosum, as it is a self-limited condition, or it may be treated with cryotherapy, salicylic acid, imiquimod, curettage, laser, or cimetidine.¹¹ On histology, epidermal budlike proliferations can be appreciated in the dermis, and characteristic large, eosinophilic, intracytoplasmic inclusion or molluscum bodies are found in the epidermis.¹²

ATLANTA – A combination of the epidermal growth factor receptor–targeted agent osimertinib (Tagrisso) with selumetinib, an investigational inhibitor of MEK1/2, was safe and associated with partial responses in about one-third of patients with non–small cell lung cancer in the phase 1b TATTON trial.

Neil Osterweil/MDedge News

In the dose-finding phase of the trial, the objective response rate was 42% for 36 patients treated with the combination either as a second- or third-line therapy, or following prior therapy for the epidermal growth factor receptor (EGFR) T70M mutation. In the dose-expansion phase of the trial, the ORR was 34% for 47 patients treated regardless of mutational status, reported Suresh S. Ramalingam, MD, from the Winship Cancer Institute at Emory University, Atlanta.

“We conclude that combining osimertinib with intermittent selumetinib is feasible with manageable toxicity and has already demonstrated promising preliminary anticancer activity,” he said at the annual meeting of the American Association for Cancer Research.

The EGFR T790M mutation is the most common cause of resistance in patients with non–small cell lung cancer (NSCLC) bearing EGFR mutations who are treated with first- or second-generation, EGFR-targeted tyrosine kinase inhibitors (TKI). Up-regulation of the RAS/RAF/MEK/ERK signaling pathway has also been implicated in NSCLC resistance to EGFR-targeted TKIs.

Selumetinib is an oral, potent, and selective inhibitor of MEK1/2 with a short half-life.

In the phase 3 SELECT-1 trial, selumetinib in combination with docetaxel did not significantly improve progression-free survival, compared with docetaxel alone as second-line therapy for patients with KRAS-mutated NSCLC.

Therapeutic rationale

Invited discussant Roy S. Herbst, MD, PhD, chief of medical oncology at Yale Cancer Center and Smilow Cancer Hospital in New Haven, Conn., said that there is sound rationale for combining osimertinib and selumetinib in EGFR-mutant NSCLC.

Neil Osterweil/MDedge News

In addition to the up-regulation of the RAS/RAF/MEK/ERK pathway noted before, resistance to osimertinib has been shown in models of EGFR-mutant NSCLC to develop from aberrant ERK signaling mediation in part by MEK1 amplification, and MEK kinase inhibitors can restore sensitivity to osimertinib in resistant cells, he said.

As previously reported, the TATTON investigators are evaluating in separate cohorts combinations of osimertinib with savolitinib, an investigational MET inhibitor for safety and activity against MET-driven NSCLC in patients with disease that has progressed on one or more prior EGFR-targeted agents, or with selumetinib for patients with advanced EGFR-mutated NSCLC that had progressed on prior therapy, including EGFR-targeted TKIs, irrespective of T790M or KRAS status.

In part A, the dose-finding phase, patients received osimertinib 80 mg daily plus intermittent or continuous selumetinib. Asian patients received continuous selumetinib 25/50 mg twice daily, while other patients received continuous selumetinib 50/75 mg twice daily, or intermittent selumetinib 75 mg twice daily 4 days on, 3 days off or on days 1 and 4 of each week of treatment.

In part B, the dose-expansion phase, patients received osimertinib plus intermittent selumetinib 75 mg twice daily on the 4 days on/3 days off schedule.

An analysis of preliminary antitumor activity in part A showed an ORR in 15 of 36 patients (42%); all were partial responses (PR). In addition, 14 patients (39%) had stable disease at 6 weeks, 3 had progressive disease, 2 died, and 2 were not evaluable. The median duration of response was 16.6 months; 77% of the patients had responses lasting at least 12 months.

In part B, 16 of 47 patients enrolled (34%) had confirmed PR, and 16 had stable disease. Of the remaining patients, 11 had disease progression, 2 died, and 2 were not evaluable. The median duration of response in this group was 9.1 months, and 31% of patients remained in response at 12 months.

The most common treatment-related adverse events in the dose-finding phase were diarrhea in 75% of patients, nausea in 39% and fatigue in 33%. Dose-limiting toxicities occurred in six patients, all of whom had been treated with continuous selumetinib. These toxicities, all grade 3, include liver enzyme increases, diarrhea, asthenia, dizziness, nausea, and pneumonitis.

The most common treatment-related adverse events in the dose-expansion phase were diarrhea in 81%, stomatitis in 32%, and paronychia in 30% of patients.

Results ‘okay’

In his discussion, Dr. Herbst commented that the part A results “look okay, until you realize that the most of the activity is in those patients who are T790M-positive, who have not been exposed in this cohort to a third-generation T790M inhibitor.” Patients with the mutation who are treated with third-generation inhibitors would be expected to have a 78% response rate.

Part B included a few more patients with responses who were negative for T790M. “My thought here is that perhaps there is a biomarker” for selecting patients most likely to benefit from the combination, he said.

For MET-negative patients, the combination appears to have manageable toxicities with noncontinuous dosing of selumetinib, and there may be benefit to using it in the first-line setting in select patients, but that will require further trials and identification of suitable biomarkers, Dr. Herbst summarized.

ATLANTA – A combination of the epidermal growth factor receptor–targeted agent osimertinib (Tagrisso) with selumetinib, an investigational inhibitor of MEK1/2, was safe and associated with partial responses in about one-third of patients with non–small cell lung cancer in the phase 1b TATTON trial.

Neil Osterweil/MDedge News

In the dose-finding phase of the trial, the objective response rate was 42% for 36 patients treated with the combination either as a second- or third-line therapy, or following prior therapy for the epidermal growth factor receptor (EGFR) T70M mutation. In the dose-expansion phase of the trial, the ORR was 34% for 47 patients treated regardless of mutational status, reported Suresh S. Ramalingam, MD, from the Winship Cancer Institute at Emory University, Atlanta.

“We conclude that combining osimertinib with intermittent selumetinib is feasible with manageable toxicity and has already demonstrated promising preliminary anticancer activity,” he said at the annual meeting of the American Association for Cancer Research.

The EGFR T790M mutation is the most common cause of resistance in patients with non–small cell lung cancer (NSCLC) bearing EGFR mutations who are treated with first- or second-generation, EGFR-targeted tyrosine kinase inhibitors (TKI). Up-regulation of the RAS/RAF/MEK/ERK signaling pathway has also been implicated in NSCLC resistance to EGFR-targeted TKIs.

Selumetinib is an oral, potent, and selective inhibitor of MEK1/2 with a short half-life.

In the phase 3 SELECT-1 trial, selumetinib in combination with docetaxel did not significantly improve progression-free survival, compared with docetaxel alone as second-line therapy for patients with KRAS-mutated NSCLC.

Therapeutic rationale

Invited discussant Roy S. Herbst, MD, PhD, chief of medical oncology at Yale Cancer Center and Smilow Cancer Hospital in New Haven, Conn., said that there is sound rationale for combining osimertinib and selumetinib in EGFR-mutant NSCLC.

Neil Osterweil/MDedge News

In addition to the up-regulation of the RAS/RAF/MEK/ERK pathway noted before, resistance to osimertinib has been shown in models of EGFR-mutant NSCLC to develop from aberrant ERK signaling mediation in part by MEK1 amplification, and MEK kinase inhibitors can restore sensitivity to osimertinib in resistant cells, he said.

As previously reported, the TATTON investigators are evaluating in separate cohorts combinations of osimertinib with savolitinib, an investigational MET inhibitor for safety and activity against MET-driven NSCLC in patients with disease that has progressed on one or more prior EGFR-targeted agents, or with selumetinib for patients with advanced EGFR-mutated NSCLC that had progressed on prior therapy, including EGFR-targeted TKIs, irrespective of T790M or KRAS status.

In part A, the dose-finding phase, patients received osimertinib 80 mg daily plus intermittent or continuous selumetinib. Asian patients received continuous selumetinib 25/50 mg twice daily, while other patients received continuous selumetinib 50/75 mg twice daily, or intermittent selumetinib 75 mg twice daily 4 days on, 3 days off or on days 1 and 4 of each week of treatment.

In part B, the dose-expansion phase, patients received osimertinib plus intermittent selumetinib 75 mg twice daily on the 4 days on/3 days off schedule.

An analysis of preliminary antitumor activity in part A showed an ORR in 15 of 36 patients (42%); all were partial responses (PR). In addition, 14 patients (39%) had stable disease at 6 weeks, 3 had progressive disease, 2 died, and 2 were not evaluable. The median duration of response was 16.6 months; 77% of the patients had responses lasting at least 12 months.

In part B, 16 of 47 patients enrolled (34%) had confirmed PR, and 16 had stable disease. Of the remaining patients, 11 had disease progression, 2 died, and 2 were not evaluable. The median duration of response in this group was 9.1 months, and 31% of patients remained in response at 12 months.

The most common treatment-related adverse events in the dose-finding phase were diarrhea in 75% of patients, nausea in 39% and fatigue in 33%. Dose-limiting toxicities occurred in six patients, all of whom had been treated with continuous selumetinib. These toxicities, all grade 3, include liver enzyme increases, diarrhea, asthenia, dizziness, nausea, and pneumonitis.

The most common treatment-related adverse events in the dose-expansion phase were diarrhea in 81%, stomatitis in 32%, and paronychia in 30% of patients.

Results ‘okay’

In his discussion, Dr. Herbst commented that the part A results “look okay, until you realize that the most of the activity is in those patients who are T790M-positive, who have not been exposed in this cohort to a third-generation T790M inhibitor.” Patients with the mutation who are treated with third-generation inhibitors would be expected to have a 78% response rate.

Part B included a few more patients with responses who were negative for T790M. “My thought here is that perhaps there is a biomarker” for selecting patients most likely to benefit from the combination, he said.

For MET-negative patients, the combination appears to have manageable toxicities with noncontinuous dosing of selumetinib, and there may be benefit to using it in the first-line setting in select patients, but that will require further trials and identification of suitable biomarkers, Dr. Herbst summarized.

As the BEST-CLI (Best Endovascular vs. Best Surgical Therapy in Patients With Critical Limb Ischemia) trial enters its last phase of new patient enrollment, I thought it was important to reflect on what this trial has meant for both the Vascular Surgery field and for me personally. This trial has been closely examining one of the most commonly treated conditions that we take care of - critical limb ischemia (more recently better described as chronic limb threatening ischemia (CLTI). BEST-CLI (ClinicalTrials.gov Identifier: NCT02060630) has the potential to be one of the most meaningful and impactful trials in the history of our profession, and that of our colleagues who also treat CLTI.  

Unlike many of the industry-sponsored endovascular device trials, vascular surgeons are at the table and are key leaders and enrollers. The results will be quoted for decades and there will be many questions answered that we have not been able to answer before - including questions that were not even on people’s minds when the trial began - such as paclitaxel-related outcomes. This trial will also provide the long-term follow-up that has limited the impact of many other peripheral arterial disease trials.

From a personal point of view, I feel like the BEST trial as always been closely connected to my practice. I have been fortunate to be partners with one of the national principal investigators, Dr. Alik Farber. We enrolled the first patient in the trial in my second month as an attending in August of 2014.  Since then, I have been able to operate on 30 patients that were randomized into the trial. It not only allowed me, as a junior attending, to get involved in a major trial, but also forced me to further develop both my open and endovascular skills so that I could provide the best care to each patient as needed.  

This trial has also moved me to see things more objectively; I am now more aware of my personal treatment biases and try more consciously to suspend them when I have equipoise between treatment options. I also continue to follow patients that I enrolled and treated over 4 years ago. This trial will challenge many wide-spread beliefs, anecdotes, and urban legends in the field of peripheral arterial disease. The results will be scrutinized and analyzed and the results will be debated – particularly by some who do not find their preconceived biases confirmed. 

A trial of this magnitude looking at limb threatening ischemia will most likely never happen again in this country. This is the one time for us as a group of professionals who care for patients with CLTI to do this correctly, rather than rely solely on data from single-arm studies, often industry-sponsored, that are typically focused on device approvals.  

It is key, as we get close to the finish line, that we suspend our preconceived notions and finish enrollment. We need to ensure this trial has adequate power to give us the answers we need the most – how to best take care of the most vulnerable and ill patients that we treat; they will greatly benefit from a clear answer as to how best we should address their limb- and life-threatening problems.

Every day in 2005, 18.5 service members and veterans committed suicide; of those, 2.7 were active-duty and non-activated Guard or Reserve. In 2015, those numbers had risen to 20.6 deaths per day, of which 3.8 were among active-duty or non-activated Guard and Reserve members. According to the VA’s most recent analysis, 7,298 current and former service members committed suicide in 2016. Of those, 902 were former Guard and Reserve members.

National Guard and Reserve members may not have veteran legal status due to their type of service, which can limit their access to VA benefits and services under current laws and regulations. In partnership with the DoD, VA now operates a mobile Vet Center to increase Guard and Reserve members’ access to mental health care.

To further help them, their families, and their health care providers, the VA also has developed a tool kit with links to mental health and suicide prevention resources that are available through the VA and their communities. “Extending support to former Guard and Reserve members at the community level is an important aspect of VA’s public health approach to preventing suicide,” said Dr. Keita Franklin, executive director for suicide prevention in the VA Office of Mental Health and Suicide Prevention.  

The resources include online suicide prevention training, mobile apps that help with managing daily stressors, and supportive services for family members who are seeking care for former service members.

InTransition, for instance, is a free confidential program that offers coaching and specialized assistance over the phone for service members who need access to mental health care. Military OneSource provides military personnel and their families with round-the-clock support for a wide range of civilian necessities, such as tax preparation and spouse employment. PsychArmor Institute provides free online education to anyone who works with, lives with, or cares for service members, veterans, and their families. The MY3-Support Network app allows users to add the contact information of 3 people they would like to talk to when they are having thoughts of suicide.

The tool kit also offers links to programs for community members who want to learn how to help prevent suicides and support families who have gone through the trauma. The #BeThere Campaign teaches how simple acts can help save the life of a veteran in crisis. The S.A.V.E. Training video, designed in collaboration with PsychArmor Institute, teaches how to demonstrate support and compassion when talking with a veteran who may be at risk. Other links lead users to ways to help those whose loved one has committed suicide, such as the Tragedy Assistance Program for Survivors (TAPS).

Further expansion of suicide prevention activities for the former Guard and Reserve population is planned for fiscal year 2019.

The Veterans Crisis Line is available with free confidential support and crisis intervention 24 hours a day, 7 days a week, 365 days a year: Call 800.273.8255 (press 1), text to 838255, or chat online at VeteransCrisisLine.net/Chat.

MILWAUKEE – Individuals with fibromyalgia had worse cognitive functioning than did a control group without fibromyalgia, according to both subjective and objective ambulatory measures.

For study participants with fibromyalgia, aggregate self-reported cognitive function over an 8-day period was poorer than for their matched controls without fibromyalgia. Objective measures of working memory, including mean and maximum error scores on a dot memory test, also were worse for the fibromyalgia group (P less than .001 for all).

Objective measures of processing speed also were slower for those with fibromyalgia, but the difference did not reach statistical significance.

These findings are “generally consistent with findings from lab-based studies of people living with [fibromyalgia], Anna Kratz, PhD, and her coauthors wrote in a poster at the scientific meeting of the American Pain Society. The study, they explained, extends laboratory-based work on cognitive dysfunction in fibromyalgia to a real-world setting by using smartphone-based capture of momentary subjective and objective cognitive functioning.

In a study of 50 adults with fibromyalgia and 50 matched controls, Dr. Kratz and her colleagues at the University of Michigan, Ann Arbor, had participants complete baseline self-report and objective measures of cognitive functioning in an in-person laboratory session. Then, participants were sent home with a wrist accelerometer and a smartphone; apps on the smartphone administered objective cognitive tests as well as subjective questions about cognitive function.

Both the subjective and objective portions of the ambulatory study were completed five times daily (on waking, and on a “quasi-random” schedule throughout the day), for at least 8 days. Day 1 was considered a “training day,” and data from that day were excluded from analysis.

To assess subjective cognitive function, patients were asked to give a momentary assessment of how slow, and how foggy, their thinking was, using a 0-100 scale. These two questions were drawn from the PROMIS Applied Cognition – General Concerns item bank. Objective measures included processing speed, captured by a 16-trial exercise of matching symbol pairs. Also, working memory was tested by completing four trials of remembering the placement of three dots in a 5x5 dot matrix.

Among the participants, 88% were female. The mean age was 45 years, and about 80% of the subjects were white. Fibromyalgia patients had more pain than did their matched controls and had poorer baseline performance on four neurocognitive tasks drawn from the National Institutes of Health Toolbox. For a flanker test, a list sorting task, a dimensional change card sort test, and a pattern comparison task, mean scores for participants with fibromyalgia ranged from 39.08 to 49.76; for the control group, mean scores ranged from 43.78 to 57.36 (P less than .05 for all).

Some people with fibromyalgia report subjective diurnal variation in cognitive function, so Dr. Kratz and her coauthors were interested in tracking performance on the ambulatory cognitive tasks over the course of the day. “Diurnal patterns and associations between objective/subjective functioning were similar across the groups,” said the authors, with no hallmark diurnal pattern for the participants with fibromyalgia. Generally, participants in both groups had the highest subjective and objective levels of performance in the morning, a dip at the first reporting time, and a gradual recovery to a level somewhat below the first morning test point by the end of the day.

Dr. Kratz and her colleagues found that in both groups, “significant associations were observed between within-person momentary changes in subjective cognitive functioning and processing speed.” This association did not hold true for working memory, however.

The findings were overall generally consistent with lab-based testing of cognitive function in individuals living with fibromyalgia, the authors said.

Dr. Kratz and her colleagues reported no outside sources of funding, and reported no conflicts of interest.

Some people with fibromyalgia report subjective diurnal variation in cognitive function, so Dr. Kratz and her coauthors were interested in tracking performance on the ambulatory cognitive tasks over the course of the day. “Diurnal patterns and associations between objective/subjective functioning were similar across the groups,” said the authors, with no hallmark diurnal pattern for the participants with fibromyalgia. Generally, participants in both groups had the highest subjective and objective levels of performance in the morning, a dip at the first reporting time, and a gradual recovery to a level somewhat below the first morning test point by the end of the day.

Dr. Kratz and her colleagues found that in both groups, “significant associations were observed between within-person momentary changes in subjective cognitive functioning and processing speed.” This association did not hold true for working memory, however.

The findings were overall generally consistent with lab-based testing of cognitive function in individuals living with fibromyalgia, the authors said.

Dr. Kratz and her colleagues reported no outside sources of funding, and reported no conflicts of interest.

The Food and Drug Administration is making changes to opioid analgesic labeling to give better information to clinicians on how to properly taper patients dependent on opioid use, according to Douglas Throckmorton, MD, deputy director for regulatory programs in the FDA’s Center for Drug Evaluation and Research.

The FDA has recently received reports that patients physically dependent on opioid pain medicines who are taken off their medication too quickly have experienced serious adverse events, such as withdrawal symptoms, uncontrolled pain, and suicide. Both the FDA and the Centers for Disease Control and Prevention offer guidelines on how to properly taper opioids, Dr. Throckmorton said, but more needs to be done to ensure that patients are being provided with the correct advice and care.

The changes to the labels will include expanded information to health care clinicians and are intended to be used when both the clinician and patient have agreed to reduce the opioid dosage. When this is discussed, factors that should be considered include the dose of the drug, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient.

Other actions the FDA is pursuing to combat opioid use disorder include working with the National Academies of Sciences, Engineering, and Medicine on guidelines for the proper opioid analgesic prescribing for acute pain resulting from specific conditions or procedures, and advancing policies that make immediate-release opioid formulations available in fixed-quantity packaging for 1 or 2 days.

“The FDA remains committed to addressing the opioid crisis on all fronts, with a significant focus on decreasing unnecessary exposure to opioids and preventing new addiction; supporting the treatment of those with opioid use disorder; fostering the development of novel pain treatment therapies and opioids more resistant to abuse and misuse; and taking action against those involved in the illegal importation and sale of opioids,” Dr. Throckmorton said.

The state of Indiana had higher hemophilia incidence and prevalence rates, compared with national estimates, according to results from a statewide epidemiologic analysis.

“[The study] aimed to identify all persons with hemophilia, including those not served by an hemophilia treatment center, who resided in Indiana,” Amanda I. Okolo, MPH, of the Indiana Hemophilia and Thrombosis Center, Indianapolis, and her colleagues wrote in Haemophilia.

The researchers retrospectively reviewed medical chart data from federally identified hemophilia treatment centers in Indiana during 2011-2013. Various data sources were used to find hemophilia cases, including administrative claims, clinic reports, and hospital records. The team estimated incidence and prevalence rates using both confirmed and possible cases of hemophilia. With respect to incidence, the calculation was based on the 10 years leading up to the study surveillance period.

“During the study period, 599, 623, and 634 male cases of hemophilia were identified in 2011, 2012 and 2013, respectively, with a total of 704 unique male cases,” the researchers wrote. Among these cases, 35.2% had factor IX deficiency and 64.8% had factor VIII deficiency.

Health care utilization was high among this group of patients, with more than 80% of cases seen at a hemophilia treatment center at least once during the 3-year study period.

The age-adjusted prevalence rate for hemophilia in 2013 was 19.4 cases per 100,000 males. The mean incidence rate over the 10 years leading up to the study period was 30.1 per 100,000, or 1 per 3,688 live male births, noticeably higher than the generally accepted national frequency of hemophilia at about 1 per 5,000 live male births.

“The estimated hemophilia prevalence in Indiana was 45% higher than previously reported in the United States,” the researchers added.

The higher prevalence could be partly caused by improvements in hemophilia care, namely increased adoption of prophylaxis. But a more important factor may be the reduction in HIV infections and the decreasing mortality from HIV among hemophilia patients.

The researchers acknowledged a key limitation of the study was the lack of data on patients assessed in other clinical settings. As a result, the reported rates could be an underestimation.

“Our results may be relevant to other countries where the hemophilia treatment center model is utilized,” they wrote.

No funding sources were reported. The authors reported having no conflicts of interest.

The buildup of mucus in the lungs was found to precede airway changes and infection in young children with cystic fibrosis (CF), according to a cross-sectional cohort study.

Zerbor/Thinkstock

It has been difficult for researchers to pinpoint the mechanisms that initiate lung disease in people with CF, because it is challenging to study young people with the disease and “CF animal models often fail to recapitulate aspects of human CF disease and yield disparate findings,” wrote Charles R. Esther Jr., MD, of the division of pediatric pulmonology at the University of North Carolina at Chapel Hill and his colleagues in Science Translational Medicine.

The researchers studied 46 clinically stable young children (aged 3.3 years, plus or minus 1.7 years) with CF and 16 age-matched controls who did not have CF, but had respiratory symptoms (aged 3.2 years, plus or minus 2.0 years) using chest CT imaging and bronchoalveolar lavage fluid. BALF samples in CF patients were collected over 62 study visits and subsequently cultured for detection and quantification of pathogens. The children with CF were enrolled in the Australian Respiratory Early Surveillance Team for Cystic Fibrosis (AREST CF) program.

“We analyzed the relationships between airway mucus, inflammation, and bacterial culture/microbiome,” the researchers wrote.

BALF total mucin levels were higher in CF samples versus non-CF controls. In addition, Dr. Esther and his colleagues found that these results were the same regardless of infection status and that increased densities of mucus flakes were also seen in samples from the CF patients. “Elevated total mucin concentrations and inflammatory markers were observed in children with CF despite a low incidence of pathogens identified by culture or molecular microbiology. This muco-inflammatory state also characterized our CF population with the earliest lung disease [without substantial CT-defined structural changes] in the setting of little or no pathogen infection,” they wrote.

Based on the findings, the investigators postulated that the airways of children with CF may show distinct defects in the clearance of recently created mucins, which could contribute to early CF lung disease.

A key limitation of the study was the prophylactic use of intermittent antibiotics. As a result, bacterial infection could have contributed to the development of early CF lung disease.

“Agents designed to remove permanent mucus covering airway surfaces of young children with CF appear to be rational strategies to prevent bacterial infection and disease progression,” they concluded.

The study was supported by the National Heart, Lung, and Blood Institute; the North Carolina Translational and Clinical Sciences Institute; the National Health and Medical Research Council; and the Cystic Fibrosis Foundation. Two coauthors reported financial affiliations with Parion Sciences.
