ABSTRACT

BACKGROUND: Efficacy of the Janus kinase (JAK) inhibitor baricitinib for severe alopecia areata (AA) continuously increased over 52 weeks in two Phase 3 trials. There are limited long-term data on JAK inhibitors in AA. OBJECTIVES: To evaluate efficacy and safety of baricitinib for severe AA through 104 weeks of continuous therapy. METHODS: Integrated data from the BRAVE-AA1 and BRAVE-AA2 Phase 3 trials included adults with Severity of Alopecia Tool (SALT) scores ≥50 (≥50% scalp hair loss) randomized to and continuously treated with 2-mg or 4-mg baricitinib through Week 104. Patients who qualified to remain on continuous treatment included subjects who achieved SALT score ≤20 at Week 52 (Week-52 responders; 2-mg: N = 65; 4-mg: N = 129) and baricitinib 4-mg-treated patients who had SALT score >20 at Week 52 but achieved SALT score ≤20 at prior visit(s) and/or had significant improvement in eyebrow or eyelash hair growth relative to baseline by Week 52 (Week-52 mixed responders; N = 110). Week-104 outcomes included the proportion of patients achieving SALT score ≤20 (≤20% scalp hair loss). Data were censored after treatment discontinuation. RESULTS: Among baricitinib 4-mg-treated and baricitinib 2-mg-treated Week-52 responders, 90.7% and 89.2%, respectively, maintained SALT score ≤20 at Week 104. Among Week-52 mixed responders, 39.1% reached SALT score ≤20 by Week 104. Continued improvement in eyebrow and eyelash regrowth was observed across groups. The most frequent treatment-emergent adverse events were COVID-19, upper respiratory tract infection, headache, nasopharyngitis, acne, urinary tract infection and creatine phosphokinase increase. CONCLUSIONS: Baricitinib demonstrated a high level of maintenance of efficacy over 104 weeks in patients with severe AA. Efficacy increased in Week-52 mixed responders, illustrating that long-term treatment is necessary to observe maximum benefit in some patients. No new safety signals were observed.

ABSTRACT

BACKGROUND: Long-term sequelae are frequent and often disabling after epidermal necrolysis (Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)). However, consensus on the modalities of management of these sequelae is lacking. OBJECTIVES: We conducted an international multicentric DELPHI exercise to establish a multidisciplinary expert consensus to standardize recommendations regarding management of SJS/TEN sequelae. METHODS: Participants were sent a survey via the online tool "Survey Monkey" consisting of 54 statements organized into 8 topics: general recommendations, professionals involved, skin, oral mucosa and teeth, eyes, genital area, mental health, and allergy workup. Participants evaluated the level of appropriateness of each statement on a scale of 1 (extremely inappropriate) to 9 (extremely appropriate). Results were analyzed according to the RAND/UCLA Appropriateness Method. RESULTS: Fifty-two healthcare professionals participated. After the first round, a consensus was obtained for 100% of 54 initially proposed statements (disagreement index < 1). Among them, 50 statements were agreed upon as 'appropriate'; four statements were considered 'uncertain', and ultimately finally discarded. CONCLUSIONS: Our DELPHI-based expert consensus should help guide physicians in conducting a prolonged multidisciplinary follow-up of sequelae in SJS-TEN.

ABSTRACT

BACKGROUND: Supportive care is the cornerstone of management of adult and paediatric Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). However, consensus on the modalities of supportive care is lacking. OBJECTIVES: Our aim in this international multicentric Delphi exercise was to establish a multidisciplinary expert consensus to standardize recommendations regarding supportive care in the acute phase of SJS/TEN. METHODS: Participants were sent a survey via the online tool SurveyMonkey, consisting of 103 statements organized into 11 topics: multidisciplinary team composition, suspect drug management, infection prevention, fluid resuscitation and prevention of hypothermia, nutritional support, pain and psychological distress management, management of acute respiratory failure, local skincare, ophthalmological management, management of other mucosa, and additional measures. Participants evaluated the level of appropriateness of each statement on a scale of 1 (extremely inappropriate) to 9 (extremely appropriate). The results were analysed according to the RAND/UCLA Appropriateness Method. RESULTS: Forty-five participants from 13 countries (on three continents) participated. After the first round, a consensus was obtained for 82.5% of the 103 initially proposed statements. After the second round, a final consensus was obtained for 102 statements. CONCLUSIONS: We have reached an international Delphi-based consensus on best supportive care practice for SJS/TEN. Our expert consensus should help guide physicians in treating patients with SJS/TEN and thereby improve short-term prognosis and the risk of sequelae.

ABSTRACT

BACKGROUND: Total-body skin examination (TBSE) by dermatologists detects incidental skin cancers, but there is insufficient evidence for screening guidelines. As a result, the decision to perform screening TBSE in patients presenting for a focused visit is left to the dermatologist's discretion. OBJECTIVES: To model the financial and time tradeoffs of risk-stratified skin cancer screening by dermatologists in patients presenting with unrelated focused complaints. METHODS: We performed an economic evaluation incorporating data from a previously published prospective multicentre international study in addition to US demographic data on age and skin phototype (SPT). RESULTS: The mean number needed to examine (NNE) for all US adults was 105 at an additional cost of $3796 per skin cancer detected when performing TBSE on a patient who presents for a focused exam. The NNE consistently decreased with increasing age and lighter SPT for every age and SPT screening threshold. The cost per person screened increased with higher age and lighter SPT owing to the higher likelihood of incurring diagnostic biopsies. The additional face-to-face time required per skin cancer detected by performing TBSE in patients who present for a focused visit was 4·5 h for all adults. We used a diverse cohort of international patients that did not include Americans and because of a low event rate, we combined detection of melanoma and nonmelanoma skin cancer. CONCLUSIONS: Incidental skin cancers are detected by screening TBSE and its value can be enhanced through consideration of patients' age and SPT, which are established and readily identifiable skin cancer risk factors. What is already known about this topic? Risk stratification of asymptomatic individuals using age and skin phototype (SPT) can enhance the value of total-body skin examination when performed in the clinic by a dermatologist. What does this study add? For every age and SPT screening threshold, the number needed to examine to identify one skin cancer consistently decreased with increasing age and lighter SPT. When deciding to perform a screening skin examination in patients presenting with a focused complaint, dermatologists may wish to consider a patient's risk using age and SPT to enhance the yield of this intervention.

ABSTRACT

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis. Treatment regimens for refractory cases are nonstandardized. Intravenous immunoglobulin (IVIG) is an emerging treatment with reported success, but the efficacy of IVIG for PG is unknown. In this systematic review of cases and case series, we assessed the efficacy of IVIG for the treatment of PG, as observed at our institution and reported in the literature. A retrospective chart review at two tertiary care hospitals between 2000 and 2015, and literature searches in PubMed/MEDLINE, EMBASE and Web of Science from all years were conducted. In total, there were 49 patients, including 43 patients from 26 articles and six institutional cases. There was complete or partial response in 43 (88%) patients and complete response in 26 (53%) patients. The mean time to initial response to treatment and treatment length were 3·5 (SD 3·3) weeks and 5·9 (SD 7·8) months, respectively. On average, 2·6 treatments had been trialled before IVIG initiation. IVIG was administered with systemic steroids in 43 (88%) cases. Mild adverse events, especially nausea and headache, were reported in 12 (24·5%) patients. Our systematic review suggests a potential role for IVIG as adjuvant therapy for refractory PG. Prospective clinical trials testing the efficacy of IVIG for refractory PG are needed to validate these findings.

ABSTRACT

BACKGROUND: Excitement around the adoption of electronic communication between physicians and patients is tempered by the possibility of increased clinical and legal risk. If patients do not read messages in a timely fashion, duplicative communication efforts may be required and patient safety may be jeopardized. OBJECTIVE: We sought to assess the prevalence and risk profile of unread messages in a mature patient portal. METHODS: We analyzed six years of messages (2005-2010) from physicians to patients to determine the prevalence and associated characteristics of unread messages in a patient portal. We focused on clinical messages, and excluded announcements. Because some physicians sent clinical messages to groups of patients, we labeled messages sent to more than 5 patients as "outreach" messages and excluded them from general analyses. We performed a chart review of 75 clinical messages to assess for harm. RESULTS: We found that 3% of clinical messages were unread after 21 days. Messages arriving outside of business hours were slightly more likely to go unread (RR 1.15 95% CI 1.11-1.19). Patients who were male (OR 1.14 CI 1.04-1.26) African American (OR 1.69 CI 1.29-2.22) or Hispanic (OR 1.74 CI 1.17-2.59), or in the lowest income group (OR 1.72 CI 1.19-2.49) were more likely to have unread messages. Chart review showed no evidence of harm, but 13% of sampled unread messages were associated with potential delays in care. Incidentally, we found 50% of the physician-initiated outreach messages were unread. CONCLUSIONS: Overall, secure messaging appears a safe form of communication, but systems to notify senders when messages are unread may have value. While most clinical messages were read, many outreach messages were not, providing caution for relying on such systems for information dissemination. Similar to other studies, differences by race and income were observed and require further study.

ABSTRACT

Freshly isolated DNA of phage PSP3, whose morphology closely resembles that of phage P2, contained both circular and linear molecules about 31 kb in length. Linear PSP3 DNA molecules possess single-stranded cohesive termini (cos). Sequencing of the fragment anticipated to contain cos revealed a 19-base sequence identical to cos of phage 186. Of the 107 bp to the right of cos, 94 were identical in 186 DNA (88% similarity), and of the 370 bp to the left, 229 were identical (62% similarity). Cos flanking sequences in both P2 and P4 were also highly conserved in PSP3. A number of restriction sites were at similar locations on the two phage DNAs. The parasitic phage P4 propagated on PSP3 lysogens. PSP3 integrates into the Escherichia coli chromosome at 27 min.
