Kimball AB, Naegeli AN, Edson-Heredia E, et al. Psychometric properties of the Itch Numeric Rating Scale in patients with moderate-to-severe plaque psoriasis.. The British journal of dermatology. 2016;175(1):157-62. doi:10.1111/bjd.14464

BACKGROUND: Itching is a profoundly distressing symptom for many patients with psoriasis, but it has not been rigorously studied using validated tools for this condition.

OBJECTIVES: This study investigated the psychometric properties of the Itch Numeric Rating Scale (Itch NRS), a single-item patient-reported outcome (PRO) measuring the worst itching severity due to psoriasis in the past 24 h.

METHODS: Using disease-specific clinician-rated and PRO data from one phase II and three phase III randomized clinical studies of subjects with moderate-to-severe plaque psoriasis, the Itch NRS was evaluated for test-retest reliability, construct validity and responsiveness. A responder definition was explored using anchor- and distribution-based methods.

RESULTS: Test-retest reliability analyses supported the reproducibility of the measure (intraclass correlation coefficient range 0·71-0·74). To support the construct validity of the Itch NRS, large cross-sectional correlations with the Dermatology Life Quality Index (DLQI) Symptoms and Feelings domain (r ≥ 0·60 at baseline and r ≥ 0·80 at week 12) supported a priori hypotheses, while large correlations (r ≥ 0·71) between changes in Itch NRS scores and changes in DLQI Symptoms and Feelings domain scores from baseline to week 12 established responsiveness. A 4-point change was optimal for demonstrating a level of clinically meaningful improvement in itch severity after 12 weeks of treatment, which corresponds with marked clinical improvements in plaque psoriasis.

CONCLUSIONS: The Itch NRS demonstrated sufficient reliability, validity and responsiveness, and appropriate interpretation standards for evaluating change over time in itch severity among patients with moderate-to-severe plaque psoriasis when validated using clinical trial data for this condition.

Clowse MEB, Feldman SR, Isaacs JD, et al. Pregnancy Outcomes in the Tofacitinib Safety Databases for Rheumatoid Arthritis and Psoriasis.. Drug safety. 2016;39(8):755-62. doi:10.1007/s40264-016-0431-z

INTRODUCTION: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), and is being investigated for the treatment of psoriasis. Both conditions can present in women of child-bearing potential, but pregnancy was an exclusion and discontinuation criterion in tofacitinib randomized controlled trials (RCTs) because of the unknown effects of tofacitinib on mother and child. Tofacitinib is a small molecule that has the potential to cross the placenta.

OBJECTIVE: The objective was to report outcomes of pregnancy cases identified through April 2014 from tofacitinib RA/psoriasis RCTs, RA post-approval non-interventional studies, and spontaneous adverse-event reporting.

METHODS: Pregnancy outcomes were categorized as follows: healthy newborn, medical termination, fetal death, congenital malformation, spontaneous abortion, or pending/lost to follow-up.

RESULTS: Out of 9815 patients, 1821 female patients of child-bearing age were enrolled in the RA/psoriasis RCTs; 47 women became pregnant, including 33 who received tofacitinib monotherapy, 13 who received combination therapy with methotrexate (RA patients only), and one patient whose therapy was still blinded. No fetal deaths were reported. One congenital pulmonary valve stenosis (monotherapy, n = 1), seven spontaneous abortions (monotherapy, n = 4; combination therapy, n = 3), and eight medical terminations (monotherapy, n = 4; combination therapy, n = 3; blinded therapy, n = 1) were identified. Remaining cases reported healthy newborns (n = 25) or were pending/lost to follow-up (n = 6). Forty-four cases of paternal exposure to tofacitinib were reported (monotherapy, n = 43; combination therapy, n = 1), including five spontaneous abortions (monotherapy, n = 4; combination therapy, n = 1), 23 healthy newborns, and 16 pending/lost to follow-up.

CONCLUSIONS: The pregnancy outcomes reported in this small number of RA/psoriasis patients appear similar to those observed in the general population and in patients treated with biologic therapies for inflammatory diseases. However, definitive conclusions cannot be drawn, and pregnancy outcomes in patients receiving tofacitinib will continue to be monitored.

Kimball AB, Okun MM, Williams DA, et al. Two Phase 3 Trials of Adalimumab for Hidradenitis Suppurativa.. The New England journal of medicine. 2016;375(5):422-34. doi:10.1056/NEJMoa1504370

BACKGROUND: Hidradenitis suppurativa is a painful, chronic inflammatory skin disease with few options for effective treatment. In a phase 2 trial, adalimumab, an antibody against tumor necrosis factor α, showed efficacy against hidradenitis suppurativa.

METHODS: PIONEER I and II were similarly designed, phase 3 multicenter trials of adalimumab for hidradenitis suppurativa, with two double-blind, placebo-controlled periods. In period 1, patients were randomly assigned in a 1:1 ratio to 40 mg of adalimumab weekly or matching placebo for 12 weeks. In period 2, patients were reassigned to adalimumab at a weekly or every-other-week dose or to placebo for 24 weeks. The primary end point was a clinical response, defined as at least a 50% reduction from baseline in the abscess and inflammatory-nodule count, with no increase in abscess or draining-fistula counts, at week 12.

RESULTS: We enrolled 307 patients in PIONEER I and 326 in PIONEER II. Clinical response rates at week 12 were significantly higher for the groups receiving adalimumab weekly than for the placebo groups: 41.8% versus 26.0% in PIONEER I (P=0.003) and 58.9% versus 27.6% in PIONEER II (P<0.001). Patients receiving adalimumab had significantly greater improvement than the placebo groups in rank-ordered secondary outcomes (lesions, pain, and the modified Sartorius score for disease severity) at week 12 in PIONEER II only. Serious adverse events in period 1 (excluding worsening of underlying disease) occurred in 1.3% of patients receiving adalimumab and 1.3% of those receiving placebo in PIONEER I and in 1.8% and 3.7% of patients, respectively, in PIONEER II. In period 2, the rates of serious adverse events were 4.6% or less in all the groups in both studies, with no significant between-group differences.

CONCLUSIONS: Treatment with adalimumab (40 mg weekly), as compared with placebo, resulted in significantly higher clinical response rates in both trials at 12 weeks; rates of serious adverse events were similar in the study groups.

Over the last decades, Life Course Research (LCR), predominantly the domain of sociology, has been increasingly applied in health research, as Life Course Epidemiology (LCE). The latter is concerned with disease patterns over time, accumulation of exposures over time, critical time periods and patterns of risk. We argue that concepts from LCR and LCE could be widely applied in dermatology, in general, and, more precisely, in the study of chronic inflammatory skin diseases, e.g. atopic eczema and psoriasis. The life course approach can generally be applied in two different ways. It may be used in the more traditional manner, in which the disease and its patterns over time are examined as the outcome vari-able. Conversely, it can examine life course as the outcome variable, which is dependent on the disease course, the treatments administered, and other physical or psychosocial environmental exposures. In dermatology, this second application of the LCR concepts is both promising and relevant because of the notable impact of chronic skin diseases on the patients' quality of life. In particular, we argue how LCR may be conducive to a better understanding of the concept of 'Cumulative Life Course Impairment', which is increasingly gaining acceptance. This approach helps identifying not only individuals at risk and particularly vulnerable patients but also critical periods for optimising interventions in order to avoid life course impairment. It also may facilitate more appropriate treatment decisions in clinical practice.

Lin RL, Garibyan L, Kimball AB, Drake LA. Systemic causes of hair loss.. Annals of medicine. 2016;48(6):393-402.

Hair loss is both a common chief complaint by patients and a clinical challenge for physicians, especially general practitioners, yet few dermatological problems yield as much patient satisfaction when resolved as hair loss. The diagnosis is often attributed to androgen-related hair loss, while other causes, some of which are life-threatening but treatable, are overlooked. We searched for relevant literature on hair loss and supported these findings with our clinical experience to identify seven major systemic etiologies of hair loss, ranging from infectious agents to consumption of unsafe supplements. Many causes are only described in the literature through case studies, though some original articles and meta-analyses are available. Careful history taking, proper examination techniques, and judicious use of laboratory tests are essential to reach at the correct diagnosis in a cost-effective manner when performing patient work-up. Such methodical evaluation of hair loss can result in the appropriate treatment plan and provide significant patient satisfaction. Key messages Hair loss is a common chief complaint and a difficult challenge for both general practitioners and dermatology consultants. We identified seven major categories of systemic hair loss etiology and present a framework for their clinical evaluation. A methodical approach to hair loss can result in the appropriate treatment plan and provide significant patient satisfaction.

Lopez I, Zapata L, Sosa JJ, et al. Acne Knowledge of Hispanic Parents of Teenagers with Mild to Moderate Acne.. Pediatric dermatology. 2016;33(5):e292-3. doi:10.1111/pde.12934

We performed a cross-sectional study of Hispanic and non-Hispanic parents of children with acne using a survey designed to determine their level of awareness of acne and its treatment; 82% of Hispanic parents and 40% of non-Hispanic parents agreed that a health care provider should treat mild acne (p < 0.001). Hispanic parents of adolescents with acne agreed more frequently than non-Hispanic parents that children with mild and moderate acne should be taken to a health care provider for treatment, but they tended not to visit health care providers. Future studies should aim to determine the reasons for this discrepancy, after which culturally sensitive educational programs can be developed to address this disparity.

Ganguli I, Chittenden E, Jackson V, Kimball AB. Survey on Clinician Perceptions and Practices Regarding Goals of Care Conversations.. Journal of palliative medicine. 2016;19(11):1215-1217.

BACKGROUND: Early conversations between clinicians and patients about goals of care may improve patients' quality of life and prevent nonbeneficial care near the end of life, but these conversations are limited in frequency and scope. To address this issue, clinicians are increasingly asked to use standardized medical order forms, like the Medical Orders for Life-Sustaining Treatment (MOLST), to document end-of-life conversations and to help ensure that patients' wishes are realized. In kind, the Centers for Medicare and Medicaid Services recently decided to reimburse physicians as well as nurse practitioners and physician assistants for these conversations.

OBJECTIVE: To explore physicians' and advanced practitioners' (APs') attitudes and behaviors around initiating and documenting goals of care conversations and to identify targets for improvement.

DESIGN: Online survey administered between October 1, 2014 and February 20, 2015.

SETTING/SUBJECTS: Physicians (n = 2492) and APs (n = 336) at an urban academic medical center.

MEASUREMENTS: Clinicians' perceptions and self-reported behaviors regarding goals of care conversations and the Massachusetts MOLST form.

RESULTS: We found that 44.0% of physicians and 33.0% of APs reported that they discussed goals of care with all patients with serious, life-limiting illness (p < 0.001). APs were more likely than physicians to report awareness of MOLST forms (55.1% vs. 45.1%, p < 0.001) but less likely to feel comfortable making recommendations on end-of-life care (25.3% vs. 41.0% recommending against resuscitation, p < 0.001; 35.1% vs. 55.7% recommending for resuscitation, p < 0.001).

CONCLUSIONS: These findings suggest the need to educate physicians and empower APs to facilitate goals of care conversations and use standardized forms, as well as an opportunity for interdisciplinary collaboration.
