RESUMO

BACKGROUND: Alopecia areata (AA) is an autoimmune hair loss disorder characterised by collapse of hair follicle immune privilege and mediated by autoreactive CD8+ T lymphocytes and natural killer cells. Treatment is often unsatisfactory. The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is implicated in the pathogenesis of AA and Janus Kinase inhibitor (JAKi) medications are promising emerging treatments for AA. OBJECTIVES: We evaluated the safety and effectiveness of tofacitinib in a real-world setting over 18 months of treatment. METHODS: A retrospective cohort study of all patients with scalp AA commenced on tofacitinib between 1 November 2016 and 31 May 2019. The primary endpoint was the percent change in Severity of Alopecia Tool (SALT) score at 18 months. RESULTS: Two hundred and two patients were included. After 18 months of treatment, 55.9%, 42.6% and 29.2% achieved 50%, 75% and 90% reductions in their SALT scores respectively. Increased duration of AA was a negative predictor of hair regrowth. Males and patients with baseline SALT ≥90 were slower to respond to treatment in the first 12 months. One hundred and twenty-four patients and 168 patients received concomitant systemic corticosteroids or low-dose oral minoxidil during tofacitinib therapy respectively. There were no serious adverse events. CONCLUSION: Tofacitinib was a safe and effective treatment for patients with moderate-to-severe AA. Further randomised controlled studies are needed to establish the optimal treatment regimen.

RESUMO

BACKGROUND: We previously reported the Alopecia Areata Consensus of Experts study, which presented results of an international expert opinion on treatments for alopecia areata. OBJECTIVE: To report the results of the Alopecia Areata Consensus of Experts international expert opinion on diagnosis and laboratory evaluation for alopecia areata. METHODS: Fifty hair experts from 5 continents were invited to participate in a 3-round Delphi process. Consensus threshold was set at greater than or equal to 66%. RESULTS: Of 148 questions, expert consensus was achieved in 82 (55%). Round 1 consensus was achieved in 10 of 148 questions (7%). Round 2 achieved consensus in 47 of 77 questions (61%). The final face-to-face achieved consensus in 25 of 32 questions (78%). Consensus was greatest for laboratory evaluation (12 of 14 questions [86%]), followed by diagnosis (11 of 14 questions [79%]) of alopecia areata. Overall, etiopathogenesis achieved the least category consensus (31 of 68 questions [46%]). LIMITATIONS: The study had low representation from Africa, South America, and Asia. CONCLUSION: There is expert consensus on aspects of epidemiology, etiopathogenesis, clinical features, diagnosis, laboratory evaluation, and prognostic indicators of alopecia areata. The study also highlights areas where future clinical research could be directed to address unresolved hypotheses in alopecia areata patient care.

RESUMO

BACKGROUND: Alopecia areata (AA) is an autoimmune hair loss condition that affects people of all ages. Early age of onset and prolonged disease duration indicate poor prognosis. Janus kinase inhibitors are being investigated in phase 3 clinical trials in adolescents and adults with AA OBJECTIVE: To evaluate the use of oral tofacitinib in pre-adolescent patients with AA. METHODS: A retrospective review of case records of all pre-adolescent patients with AA treated with oral tofacitinib in a single center between 2018 and 2019. RESULTS: Fourteen patients were identified, aged 7 to 11 years. Nine patients experienced clinically significant improvement in their SALT (Severity of Alopecia Tool) score. Three patients achieved complete remission (SALT score of 0), seven (63.6%) achieved over 50% improvement in SALT score from baseline. One patient had no change from baseline, another experienced additional hair loss. After an average of 9 months of treatment, the median SALT score improvement was 67.7%. The improvement was similar in patients with baseline SALT scores greater than 50 and those with baseline SALT scores below 10. Adverse events were mild. LIMITATIONS: The retrospective nature of the data, small sample size, lack of a control group, referral bias to a specialist hair center, and concomitant use of other medications including oral minoxidil in all patients. CONCLUSION: There is a role for tofacitinib as a systemic therapy in AA and this should be further evaluated in prospective clinical trials in pre-adolescents.

RESUMO

BACKGROUND: A systematic review failed to identify any systemic therapy used in alopecia areata (AA) where use is supported by robust evidence from high-quality randomized controlled trials. OBJECTIVE: To produce an international consensus statement on the use and utility of various treatments for AA. METHODS: Fifty hair experts from 5 continents were invited to participate in a 3-round Delphi process. Agreement of 66% or greater was considered consensus. RESULTS: In the first round, consensus was achieved in 22 of 423 (5%) questions. After a face-to-face meeting in round 3, overall, consensus was achieved for only 130 (33%) treatment-specific questions. There was greater consensus for intralesional treatment of AA (19 [68%]) followed by topical treatment (25 [43%]). Consensus was achieved in 45 (36%) questions pertaining to systemic therapies in AA. The categories with the least consensus were phototherapy and nonprescription therapies. LIMITATIONS: The study included a comprehensive list of systemic treatments for AA but not all treatments used. CONCLUSION: Despite divergent opinions among experts, consensus was achieved on a number of pertinent questions. The concluding statement also highlights areas where expert consensus is lacking and where an international patient registry could enable further research.

RESUMO

Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are lymphocytic, cicatricial alopecias. Clinically, LPP presents with multifocal patchy alopecia, while FFA, considered a variant of LPP, results in hairline recession. Frontal recession in FFA may progress as far as the mid-scalp and infrequently beyond. Treatment to arrest the inflammatory process can be challenging and response variable. We report a case of recalcitrant lichen planopilaris and frontal fibrosing alopecia demonstrating significant clinical improvement after four doses of the interleukin-23 monoclonal antibody tildrakizumab.

RESUMO

Alopecia areata (AA) severity varies from a single small patch to complete loss of scalp hair, body hair, eyelashes and eyebrows. While 40% of all affected individuals only ever get one patch and will achieve a spontaneous complete durable remission within 6 months, 27% will develop additional patches but still achieve complete durable remission within 12 months and 33% will develop chronic AA. Without systemic treatment, 55% of individuals with chronic AA will have persistent multifocal relapsing and remitting disease, 30% will ultimately develop alopecia totalis and 15% will develop alopecia universalis. The unpredictable course and psychological distress attributable to AA contributes to the illness associated with AA. Numerous topical, intralesional and systemic agents are currently used to treat AA; however, there is a paucity of data evaluating their use, effectiveness and tolerability. Topical therapy, including topical glucocorticosteroids, minoxidil and immunotherapy, can be used in cases of limited disease. There are no universally agreed indications for initiating systemic treatment for AA. Possible indications for systemic treatment include rapid hair loss, extensive disease (≥50% hair loss), chronic disease, severe distress or a combination of these factors. Currently available systemic treatments include glucocorticosteroids, methotrexate, ciclosporin, azathioprine, dapsone, mycophenolate mofetil, tacrolimus and sulfasalazine. The optimal treatment algorithm has not yet been described. The purpose of this consensus statement is to outline a treatment algorithm for AA, including the indications for systemic treatment, appropriate choice of systemic treatment, satisfactory outcome measures and when to discontinue successful or unsuccessful treatment.

RESUMO

BACKGROUND/OBJECTIVES: The simplified psoriasis index (SPI) is a three-part multidimensional tool incorporating disease severity, psychosocial impact and historical course completed by the health-care professional (professional SPI, [proSPI]) or the patient (self-assessment SPI, [saSPI]). We aimed to assess the validity and response distribution of proSPI and saSPI in patients with psoriasis undergoing phototherapy. METHODS: The validity and response distribution of SPI was assessed by recording saSPI and proSPI in patients with psoriasis before and after a course of phototherapy. Recruitment ended once 100 complete data sets were available for analysis. RESULTS: Altogether 52 of the 100 patients evaluated were male and most (93) underwent narrowband UVB phototherapy. There was a close correlation between the proSPI-current severity score (proSPI-s) with the psoriasis area and severity index (PASI) score (r = 0.76, r = 0.86) before and after treatment, respectively. Although pretreatment correlation between the saSPI-current severity score (saSPI-s) and PASI was weak (r = 0.39), a more close correlation was noted at the end of treatment (r = 0.50). A moderate correlation was observed between the SPI-psychosocial impact score (SPI-p) and the dermatology life quality index (DLQI), both before and after phototherapy (r = 0.64, r = 0.73). The SPI had wide response distributions in all three domains. CONCLUSIONS: Both versions of SPI demonstrated wide response distributions and the proSPI-s in particular was shown to have good validity with PASI.

RESUMO

Cutaneous collagenous vasculopathy is a rare microangiopathy first described by Salama and Rosenthal in 2000. Several cases have been reported to date, describing distinct histological findings of thick hyaline collagenous blood vessel walls in the superficial dermis. Clinical confusion can arise with generalised essential telangiectasia. We report a case occurring in a 76-year-old woman who presented with a 2-year history of a telangiectatic rash progressing from her knees upwards. The diagnosis was confirmed on skin biopsy and treatment with pulsed dye laser was later initiated at the patient's request.
