BACKGROUND: Baricitinib, an oral selective JAK1/JAK2 inhibitor, is approved for the treatment of adults with severe alopecia areata (AA). OBJECTIVE: To evaluate differences in response up to week 52 among subgroups based on the baseline severity of AA assessed with the Severity of Alopecia Tool (SALT) score. METHODS: Data were pooled from BRAVE-AA1 and BRAVE-AA2, two randomized, placebo-controlled, phase 3 trials, which enrolled adults with a SALT score ≥ 50...

IMPORTANCE: Alopecia areata (AA) is characterized by hair loss ranging from patches of hair loss to more extensive forms, including alopecia totalis (AT) and alopecia universalis (AU). There is a lack of consensus for treatment. Understanding current practice patterns could help the identification of treatment needs and development of standards of care. OBJECTIVE: To review treatment patterns for adults with AA in the US between 2015 and 2020. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study used medicine and pharmacy claims for commercially insured individuals from the IBM MarketScan Research Database to assess adults (≥18 years) newly treated for AA between October 15, 2015, and February 28, 2020...

INTRODUCTION: Ritlecitinib demonstrated efficacy in patients with alopecia areata (AA) in the ALLEGRO phase 2b/3 study (NCT03732807). However, hair loss presentation may vary based on location (e.g., scalp, eyebrow/eyelash, body). Here, we sought to identify distinct hair loss profiles at baseline and evaluate whether they affected the efficacy of ritlecitinib. METHODS: Patients with AA aged ≥ 12 years with ≥ 50% scalp hair loss were randomized to daily ritlecitinib 10 mg (assessed for dose ranging only), 30 or 50 mg (± 4-week, 200-mg loading dose), or placebo for 24 weeks...

Complete scalp hair loss can be a source of distress for affected children and their families. In addition to infectious and trauma-related causes of hair loss, infants and children may present with total scalp alopecia arising from a range of genetic predispositions. Our objective with this review was to identify the common genetic conditions in children with complete scalp alopecia. The PubMed Database was reviewed for all articles from 1962 to 2019 containing the search terms related to genetic alopecia...

INTRODUCTION: Alopecia areata (AA) is an autoimmune non-scarring hair loss. The role of micronutrients such as iron, zinc, and vitamins, especially vitamin D, on the natural hair cycle is well defined in literature. This study aims to evaluate the correlation between vitamin D and CRP levels in patients with alopecia areata. METHODS: This cross-sectional study was performed from beginning of October 2020 until end of December 2021. Alopecia areata patients over 18 years of age gave their written consent to participate in the study...

Drug-induced alopecia areata is a rare adverse event wherein medications such as antimicrobials, anticonvulsants, and biologics, trigger the premature transition of actively growing hairs into the telogen phase. Herein, a unique case of alopecia universalis observed during a clinical trial involving sacubitril/alisartan, a novel angiotensin receptor-neprilysin inhibitor (ARNI) has been reported. This case contributes to the range of cutaneous reactions that might be observed in association with ARNI therapy...

Alopecia areata is an autoimmune disorder characterized by hair loss, for which there are few treatment options. This claims-based study characterized recent real-world treatment patterns among patients in the USA with alopecia areata, including the subtypes alopecia totalis and alopecia universalis, in the first year after diagnosis of an episode of alopecia areata. Approximately 5% of all patients (adults (age ≥ 18 years), n = 7,703; adolescents (age 12-17 years), n = 595) had alopecia totalis or alopecia universalis...

Janus kinase (JAK) inhibitors have ushered in a new era in alopecia areata (AA). Historically, moderate-to-severe AA was refractory to treatment. JAK inhibitors have changed that; now, treatment of moderate-to-severe AA is possible. Here, we briefly review the history of and rationale for JAK inhibitor treatment of AA, phase 3 clinical trial data, and considerations regarding differences among JAK inhibitors, safety, and patient selection.

Abrocitinib, a highly selective inhibitor of Janus kinase 1 (JAK1), has been approved for the treatment of moderate-to-severe atopic dermatitis (AD). Patients with alopecia universalis (AU) co-morbid with AD receiving abrocitinib achieved clinical remission for both diseases. We report a case of a patient with AU after drug reaction with eosinophilia and systemic symptoms (DRESS) who responded well to abrocitinib therapy at a dose of 100 and 200 mg once daily. In addition, we reviewed cases of alopecia after DRESS and explored the underlying mechanisms for alopecia areata (AA) being an autoimmune sequela...

Alopecia areata (AA) is a chronic, non-scarring, immune-mediated skin disease that affects approximately 0.5-2% of the global population. The etiology of AA is complex and involves genetic and environmental factors, with significant advancements in genetic research occurring in recent years. In addition to well-known genes such as PTPN22 , CTLA4 , and IL2 , which have been widely supported as being associated with AA, an increasing number of specific gene-related loci have been discovered through advances in genetic research...

Messenger RNA vaccines against SARS-CoV-2 infection, or COVID-19 dramatically changed the landscape of the fight against COVID-19 pandemic. However, they might be associated with various side effects, such as myocarditis. Herein we report a case of alopecia universalis occurring after injection of an mRNA COVID-19 vaccine in a Japanese patient. Healthcare workers should be aware of this rather rare complication after vaccinations.

BACKGROUND: Alopecia areata (AA) is a disease featured by recurrent, non-scarring hair loss with a variety of clinical manifestations. The outcome of AA patients varies greatly. When they progress to the subtypes of alopecia totalis (AT) or alopecia universalis (AU), the outcome is unfavorable. Therefore, identifying clinically available biomarkers that predict the risk of AA recurrence could improve the prognosis for AA patients. METHODS: In this study, we conducted weighted gene co-expression network analysis (WGCNA) and functional annotation analysis to identify key genes that correlated to the severity of AA...

INTRODUCTION: Alopecia areata (AA) is an autoimmune disease with an underlying immuno-inflammatory pathogenesis. Treatments can include systemic corticosteroids and immunomodulators (such as Janus kinase inhibitors); these medications may be associated with a risk of some adverse events. However, large-scale observational studies of baseline incidence rates (IRs) of infection, cardiovascular disease, malignancy, and thromboembolism in US patients with AA, including those with alopecia totalis or alopecia universalis (AT/AU), are limited...

Alopecia areata (AA) is associated with an increased burden of autoimmune and inflammatory disease and mental health conditions that may have a negative impact on quality of life. However, the exact burden of comorbidities on US patients with AA and the clinical subtypes alopecia totalis (AT) and alopecia universalis (AU) compared with those without AA is not well understood. This retrospective cohort study aimed to assess the incidence rates and prevalence of AA and its clinical subtypes and examine the autoimmune and inflammatory disease and mental health condition diagnosis burden in US patients with AA and a matched cohort without AA...

IMPORTANCE: Alopecia areata (AA) is associated with diverse autoimmune and psychiatric disorders. However, an investigation on the long-term outcomes for offspring born to mothers diagnosed with AA is lacking. OBJECTIVE: To investigate the risks for autoimmune, inflammatory, atopic, thyroid, and psychiatric outcomes of offspring born to mothers with AA. DESIGN, SETTING, AND PARTICIPANTS: This retrospective population-based birth cohort study used the linked birth registration database with the Nationwide Health Insurance Service database of Korea...

Immune checkpoint blockades have been widely used to treat various malignancies. Programmed cell death protein 1 (PD-1) inhibitor-induced alopecia areata, one of the immune-related adverse events, is rarely reported. We present a case of alopecia universalis during the treatment of Sintilimab, a monoclonal anti-PD-1 antibody, in a patient with hepatocellular carcinoma. A 65-year-old male was diagnosed with hepatocellular carcinoma in liver segment VI (S6) and chose to receive Sintilimab due to predicted insufficient residual liver volume for hepatectomy...

Alopecia totalis (AT) and alopecia universalis (AU) is known to have a poor prognosis with high relapse rate, and treatment failure is observed in most patients, regardless of the type of therapy. Although treatment and the prognosis of AT and AU have improved in recent years, old data are routinely cited in recent review papers without questioning them. The authors aimed to study the clinical characteristics and prognosis of AT and AU to update and compare the results with those of previously reported studies...
