The Alopecia Areata Severity and Morbidity Index (ASAMI) Study: Results From a Global Expert Consensus Exercise on Determinants of Alopecia Areata Severity.

Importance: Current measures of alopecia areata (AA) severity, such as the Severity of Alopecia Tool score, do not adequately capture overall disease impact. Objective: To explore factors associated with AA severity beyond scalp hair loss, and to support the development of the Alopecia Areata Severity and Morbidity Index (ASAMI). Evidence Review: A total of 74 hair and scalp disorder specialists from multiple continents were invited to participate in an eDelphi project consisting of 3 survey rounds. The first 2 sessions took place via a text-based web application following the Delphi study design. The final round took place virtually among participants via video conferencing software on April 30, 2022. Findings: Of all invited experts, 64 completed the first survey round (global representation: Africa [4.7%], Asia [9.4%], Australia [14.1%], Europe [43.8%], North America [23.4%], and South America [4.7%]; health care setting: public [20.3%], private [28.1%], and both [51.6%]). A total of 58 specialists completed the second round, and 42 participated in the final video conference meeting. Overall, consensus was achieved in 96 of 107 questions. Several factors, independent of the Severity of Alopecia Tool score, were identified as potentially worsening AA severity outcomes. These factors included a disease duration of 12 months or more, 3 or more relapses, inadequate response to topical or systemic treatments, rapid disease progression, difficulty in cosmetically concealing hair loss, facial hair involvement (eyebrows, eyelashes, and/or beard), nail involvement, impaired quality of life, and a history of anxiety, depression, or suicidal ideation due to or exacerbated by AA. Consensus was reached that the Alopecia Areata Investigator Global Assessment scale adequately classified the severity of scalp hair loss. Conclusions and Relevance: This eDelphi survey study, with consensus among global experts, identified various determinants of AA severity, encompassing not only scalp hair loss but also other outcomes. These findings are expected to facilitate the development of a multicomponent severity tool that endeavors to competently measure disease impact. The findings are also anticipated to aid in identifying candidates for current and emerging systemic treatments. Future research must incorporate the perspectives of patients and the public to assign weight to the domains recognized in this project as associated with AA severity.

Efficacy of Methotrexate Alone vs Methotrexate Plus Low-Dose Prednisone in Patients With Alopecia Areata Totalis or Universalis: A 2-Step Double-Blind Randomized Clinical Trial.

Importance: Poor therapeutic results have been reported in patients with alopecia areata totalis (AT) or universalis (AU), the most severe and disabling types of alopecia areata (AA). Methotrexate, an inexpensive treatment, might be effective in AU and AT. Objective: To evaluate the efficacy and tolerance of methotrexate alone or combined with low-dose prednisone in patients with chronic and recalcitrant AT and AU. Design, Setting, and Participants: This academic, multicenter, double-blind, randomized clinical trial was conducted at 8 dermatology departments at university hospitals between March 2014 and December 2016 and included adult patients with AT or AU evolving for more than 6 months despite previous topical and systemic treatments. Data analysis was performed from October 2018 to June 2019. Interventions: Patients were randomized to receive methotrexate (25 mg/wk) or placebo for 6 months. Patients with greater than 25% hair regrowth (HR) at month 6 continued their treatment until month 12. Patients with less than 25% HR were rerandomized: methotrexate plus prednisone (20 mg/d for 3 months and 15 mg/d for 3 months) or methotrexate plus placebo of prednisone. Main Outcome and Measures: The primary end point assessed on photos by 4 international experts was complete or almost complete HR (Severity of Alopecia Tool [SALT] score <10) at month 12, while receiving methotrexate alone from the start of the study. Main secondary end points were the rate of major (greater than 50%) HR, quality of life, and treatment tolerance. Results: A total of 89 patients (50 female, 39 male; mean [SD] age, 38.6 [14.3] years) with AT (n = 1) or AU (n = 88) were randomized: methotrexate (n = 45) or placebo (n = 44). At month 12, complete or almost complete HR (SALT score <10) was observed in 1 patient and no patient who received methotrexate alone or placebo, respectively, in 7 of 35 (20.0%; 95% CI, 8.4%-37.0%) patients who received methotrexate (for 6 or 12 months) plus prednisone, including 5 of 16 (31.2%; 95% CI, 11.0%-58.7%) who received methotrexate for 12 months and prednisone for 6 months. A greater improvement in quality of life was observed in patients who achieved a complete response compared with nonresponder patients. Two patients in the methotrexate group discontinued the study because of fatigue and nausea, which were observed in 7 (6.9%) and 14 (13.7%) patients receiving methotrexate, respectively. No severe treatment adverse effect was observed. Conclusions and Relevance: In this randomized clinical trial, while methotrexate alone mainly allowed partial HR in patients with chronic AT or AU, its combination with low-dose prednisone allowed complete HR in up to 31% of patients. These results seem to be of the same order of magnitude as those recently reported with JAK inhibitors, with a much lower cost. Trial Registration: ClinicalTrials.gov Identifier: NCT02037191.

Louis Armstrong's Lip Problems: Satchmo's Syndrome Reviewed.

Rupture of the orbicularis muscle of the lips in wind musicians is known as Satchmo's syndrome because it is assumed that Louis Armstrong (nicknamed Satchmo) suffered this condition. But whether Louis Armstrong really had this problem or not has never been documented. AIMS: This study is a biographical review and an analysis of the existing photographs of Armstrong's lip with the aim of better understanding the origin and progression of his disorder. METHODS: A review was made of the most important biographies, newspapers, and magazines referring to Louis Armstrong and medical reports about Satchmo's syndrome. Major archives related to Louis Armstrong were searched for documents, photographs, articles, videos, letters, and other items, using the terms "lip," "embouchure," "mouth," and "problem." Information was sought on Armstrong's playing technique, playing schedule, lip changes, lip problems, and other related health issues. RESULTS: It was found that Louis Armstrong suffered dermatological lip problems due to his intense playing schedule and the way he played from the very beginning of his career. This first created swelling and superficial erosions that later became cracks and fissures. These lesions finally produced ulcers which evolved into scar tissue after healing. This made the mucosa thicker and stiffer, making it more difficult for the lip to vibrate and forcing him to increase the tension and pressure in the area in order to play the trumpet. This created a vicious cycle with the scar tissue leading to further problems. These injuries even bled several times while he was playing and, on some occasions, left his mouth and clothes bloodied in the middle of concerts. His biography does not make any reference to difficulties or symptoms that could indicate that he had orbicularis oris muscle rupture, except for the fact that he had trouble playing, a symptom common to any injury to the lips in a wind instrument player. CONCLUSION: Analysis of the existing data indicates that Louis Armstrong's lip problems were most likely due to mucosa fibromatous hyperplasia resulting from chronic microtrauma rather than a rupture of the orbicularis oris muscle. Therefore, we propose that this disorder should no longer be referred to as Satchmo's syndrome.

What's New in Therapy for Male Androgenetic Alopecia?

Male androgenetic alopecia is a common condition and represents a major concern for patients who experience this condition. While there are different treatments to stop hair loss and improve hair density, the 5-alpha reductase inhibitors have demonstrated to be effective in improving androgenetic alopecia in men and can maintain a positive response for many years. Oral finasteride 1 mg is a US FDA-approved option, but dutasteride 0.5 mg has been proven to induce better responses, especially in the frontal area. Both have been shown to be safe in clinical trials but there is widespread concern about sexual adverse effects among patients. The use of topical finasteride has increased during the last few years as a useful option to avoid systemic therapy. The efficacy of topical finasteride 0.25% daily has been demonstrated in clinical trials, with a less marked decrease in serum dihydrotestosterone levels than with oral intake. Mesotherapy with dutasteride has also become more widespread recently, although evidence of its effectiveness is limited to retrospective studies in real clinical practice. The use of oral minoxidil in androgenetic alopecia has not been approved by the FDA, however several clinical studies have shown that it is an effective treatment option. The initial dose recommended to treat male hair loss is 2.5 mg daily, although the dose is frequently increased to 5 mg daily. The main adverse effect of oral minoxidil is hypertrichosis, followed by dizziness or lower limb edema, which are much less common. Platelet-rich plasma is a non-pharmacological option to treat male androgenetic alopecia, with some clinical trials demonstrating an improvement in hair count after several months. Among the published studies, the main limitation to compare its efficacy is the heterogeneity of the procedure. The most frequent regimens propose treatment every 4 weeks for 3 months initially to assess the individual response. Another treatment alternative is the use of light devices with wavelengths of between 630 and 660 nm, known as low-level laser therapy. These devices can be used at home every day for 15-30 min. Their efficacy has been shown in a limited number of clinical trials; however, there is a lack of evidence about the efficacy of these devices compared with other medical options or as a complementary therapy in hair loss. The pipeline of potential new treatments for male androgenetic alopecia is strong. Pyrilutamide and GT20029 are being studied as topical antagonists of the androgen receptor, while cetirizine is another topical option with some initial promising results. Furthermore, according to isolated studies with heterogeneous treatment schemes, the use of botulinum toxin in the scalp might improve androgenetic alopecia, and lastly, scalp threading might increase the total hair count as growth factors are released during implantation.

Mini pulse corticosteroid therapy with oral dexamethasone for moderate to severe alopecia areata: A multicentric study.

Extensive subtypes of alopecia areata (AA) (totalis, universalis, or multifocal) still have no approved and effective treatments in Europe, although Janus kinase inhibitors, such as baricitinib, are promising treatments that have been recently approved by the FDA. Nowadays, the higher costs and the lower experience with Janus kinase inhibitors, provide more difficulties in its accessibility. On the other hand, different corticosteroids regimens have been evaluated with conflicting results from decades. In 2016, a new regimen of mini pulse corticosteroid therapy with oral dexamethasone (MPCT-OD) 0.1mg/kg/day twice per week for adult patients with alopecia areata totalis or universalis, was reported to be effective with a lower rate of adverse effects. We performed a retrospective and multicentric study to collect data from patients with extensive forms of alopecia areata who had received MPCTOD (0.1 mg/kg/day twice weekly of dexamethasone) for at least 24 weeks. We included adult patients (≥18 years) with extensive forms of AA (SALT index ≥ 10) that did not respond to previous treatments. Variables including epidemiological and clinical data were recorded. Therapeutic response was assessed through the % change in SALT score (from 0 to 100%) and the changes in eyebrow and eyelash alopecia index (EBA, ELA) from baseline to 24 weeks after the beginning of the treatment. Dexamethasone dosage, duration of the treatment, time until response, time to relapse, adverse effects, and discontinuation were also recorded.

Efficiency of Hair Detection in Hair-to-Hair Matched Trichoscopy.

Introduction: Precise evaluation of changes in hair count is crucial for monitoring progression of hair loss and the effects of treatment. The focus of this study is the comparison of the various examination and assessment techniques in terms of the precision of hair count change observed in trichoscopy images. Methods: Controlled hair extraction of the same scalp spot was used to simulate hair loss, and the different examination techniques were performed to detect this change. The investigators who performed the counting were blinded. Results: For trichoscopy images, the average error in determining the terminal hair count change (relative to total hair count) was 9 ± 1% for automatic assessment with manual correction and 0.4 ± 0.2% for hair-to-hair matched images. For phototrichogram, the automatic measurement results were found to deviate from truth on average by 12 ± 2%. The manually corrected hair count results were much closer to the truth with average deviation at the level of 7 ± 1%. The hair-to-hair matched results corresponded to approximately 0.6 ± 0.3% average discrepancy. Conclusion: Combination of manually corrected image processing, follicular mapping, and hair-to-hair matching appears to be the most precise way of evaluating the change in hair count over time. These novel techniques should be considered valuable, especially in research and clinical trials.

Automatic SCOring of Atopic Dermatitis Using Deep Learning: A Pilot Study.

Atopic dermatitis (AD) is a chronic, itchy skin condition that affects 15-20% of children but may occur at any age. It is estimated that 16.5 million US adults (7.3%) have AD that initially began at age >2 years, with nearly 40% affected by moderate or severe disease. Therefore, a quantitative measurement that tracks the evolution of AD severity could be extremely useful in assessing patient evolution and therapeutic efficacy. Currently, SCOring Atopic Dermatitis (SCORAD) is the most frequently used measurement tool in clinical practice. However, SCORAD has the following disadvantages: (i) time consuming-calculating SCORAD usually takes about 7-10 minutes per patient, which poses a heavy burden on dermatologists and (ii) inconsistency-owing to the complexity of SCORAD calculation, even well-trained dermatologists could give different scores for the same case. In this study, we introduce the Automatic SCORAD, an automatic version of the SCORAD that deploys state-of-the-art convolutional neural networks that measure AD severity by analyzing skin lesion images. Overall, we have shown that Automatic SCORAD may prove to be a rapid and objective alternative method for the automatic assessment of AD, achieving results comparable with those of human expert assessment while reducing interobserver variability.

Assessment of the Genetic Spectrum of Uncombable Hair Syndrome in a Cohort of 107 Individuals.

Importance: Uncombable hair syndrome (UHS) is a rare hair shaft anomaly that manifests during infancy and is characterized by dry, frizzy, and wiry hair that cannot be combed flat. Only about 100 known cases have been reported so far. Objective: To elucidate the genetic spectrum of UHS. Design, Setting, and Participants: This cohort study includes 107 unrelated index patients with a suspected diagnosis of UHS and family members who were recruited worldwide from January 2013 to December 2021. Participants of all ages, races, and ethnicities were recruited at referral centers or were enrolled on their own initiative following personal contact with the authors. Genetic analyses were conducted in Germany from January 2014 to December 2021. Main Outcomes and Measures: Clinical photographs, Sanger or whole-exome sequencing and array-based genotyping of DNA extracted from blood or saliva samples, and 3-dimensional protein modeling. Descriptive statistics, such as frequency counts, were used to describe the distribution of identified pathogenic variants and genotypes. Results: The genetic characteristics of patients with UHS were established in 80 of 107 (74.8%) index patients (82 [76.6%] female) who carried biallelic pathogenic variants in PADI3, TGM3, or TCHH (ie, genes that encode functionally related hair shaft proteins). Molecular genetic findings from 11 of these 80 individuals were previously published. In 76 (71.0%) individuals, the UHS phenotype were associated with pathogenic variants in PADI3. The 2 most commonly observed PADI3 variants account for 73 (48.0%) and 57 (37.5%) of the 152 variant PADI3 alleles in total, respectively. Two individuals carried pathogenic variants in TGM3, and 2 others carried pathogenic variants in TCHH. Haplotype analyses suggested a founder effect for the 4 most commonly observed pathogenic variants in the PADI3 gene. Conclusions and Relevance: This cohort study extends and gives an overview of the genetic variant spectrum of UHS based on molecular genetic analyses of the largest worldwide collective of affected individuals, to our knowledge. Formerly, a diagnosis of UHS could only be made by physical examination of the patient and confirmed by microscopical examination of the hair shaft. The discovery of pathogenic variants in PADI3, TCHH, and TGM3 may open a new avenue for clinicians and affected individuals by introducing molecular diagnostics for UHS.

Trichodynia and telogen effluvium in COVID-19 patients: Results of an international expert opinion survey on diagnosis and management.

BACKGROUND: The cutaneous manifestations of COVID-19 may be useful disease markers and prognostic indicators. Recently, postinfectious telogen effluvium and trichodynia have also been reported. OBJECTIVE: To evaluate the presence of trichodynia and telogen effluvium in patients with COVID-19 and describe their characteristics in relation to the other signs and symptoms of the disease. METHODS: Patients with a history of COVID-19 presenting to the clinics of a group of hair experts because of telogen effluvium and/or scalp symptoms were questioned about their hair signs and symptoms in relation to the severity of COVID-19 and associated symptoms. RESULTS: Data from 128 patients were collected. Telogen effluvium was observed in 66.3% of the patients and trichodynia in 58.4%. Trichodynia was associated with telogen effluvium in 42.4% of the cases and anosmia and ageusia in 66.1% and 44.1% of the cases, respectively. In majority (62.5%) of the patients, the hair signs and symptoms started within the first month after COVID-19 diagnosis, and in 47.8% of the patients, these started after 12 weeks or more. LIMITATIONS: The recruitment of patients in specialized hair clinics, lack of a control group, and lack of recording of patient comorbidities. CONCLUSION: The severity of postviral telogen effluvium observed in patients with a history of COVID-19 infection may be influenced by COVID-19 severity. We identified early-onset (<4 weeks) and late-onset (>12 weeks) telogen effluvium.

[Congenital hair shaft anomalies].

This review covers congenital hair shaft anomalies, which are conditions affecting hair shaft morphology. Sometimes suspected with the naked eye, often in need of microscopic examination to properly diagnose, these conditions could lead to the discovery of a complex genetic syndrome. Further knowledge is needed in order to establish a diagnosis, approach treatment alternatives and shed light on prognoses, which benefits patients. Our aim is to provide an updated summary of pathogenesis, clinical findings, treatment options and prognosis as well as psychosocial impact.

A Global eDelphi Exercise to Identify Core Domains and Domain Items for the Development of a Global Registry of Alopecia Areata Disease Severity and Treatment Safety (GRASS).

Importance: A recent expert consensus exercise emphasized the importance of developing a global network of patient registries for alopecia areata to redress the paucity of comparable, real-world data regarding the effectiveness and safety of existing and emerging therapies for alopecia areata. Objective: To generate core domains and domain items for a global network of alopecia areata patient registries. Evidence Review: Sixty-six participants, representing physicians, patient organizations, scientists, the pharmaceutical industry, and pharmacoeconomic experts, participated in a 3-round eDelphi process, culminating in a face-to-face meeting at the World Congress of Dermatology, Milan, Italy, June 14, 2019. Findings: Ninety-two core data items, across 25 domains, achieved consensus agreement. Twenty further noncore items were retained to facilitate data harmonization in centers that wish to record them. Broad representation across multiple stakeholder groups was sought; however, the opinion of physicians was overrepresented. Conclusions and Relevance: This study identifies the domains and domain items required to develop a global network of alopecia areata registries. These domains will facilitate a standardized approach that will enable the recording of a comprehensive, comparable data set required to oversee the introduction of new therapies and harness real-world evidence from existing therapies at a time when the alopecia areata treatment paradigm is being radically and positively disrupted. Reuse of similar, existing frameworks in atopic dermatitis, produced by the Treatment of Atopic Eczema (TREAT) Registry Taskforce, increases the potential to reuse existing resources, creates opportunities for comparison of data across dermatology subspecialty disease areas, and supports the concept of data harmonization.

The Alopecia Areata Consensus of Experts (ACE) study part II: Results of an international expert opinion on diagnosis and laboratory evaluation for alopecia areata.

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.
