Successful treatment of severe atopic dermatitis and alopecia universalis with upadacitinib in a 29-year-old male patient.

A 29-year-old male patient had severe atopic dermatitis (AD) and alopecia universalis (AU) that could not be controlled by using classic therapy. He started taking upadacitinib and achieved an excellent response for both his AD and AU. Thus, upadacitinib represents a promising therapeutic approach for patients with severe AD and alopecia areata.

Calcinosis universalis accompanied by symptomatic systemic sclerosis.

Calcinosis cutis is represented by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. Calcinosis can lead to repeated episodes of local inflammation and repeated infections, resulting in pain and functional disability, and even death. Here, we present a case of a patient with SSc who experienced calcinosis universalis and eventually died from recurrent infections at the sacrococcygeal calcification.

Rapid hair regrowth in an alopecia universalis patient with deucravacitinib: A case report.

Alopecia universalis is a severe, difficult to treat variant of alopecia areata that results in loss of hair on the scalp, eyebrows, eyelashes, and extremities. Deucravacitinib, a selective TYK2 inhibitor, has been recently approved in Canada, opening the door to novel uses of the drug. We present the case of a patient known for psoriasis who developed alopecia universalis resistant to many interventions (topical minoxidil and topical, intralesional, and systemic corticosteroids). We report the first case of successful rapid hair regrowth after starting deucravacitinib, which should prompt further inquiry into the use of TYK2 inhibitors in the management of alopecia areata.

Post-Traumatic Stress Disorder in Patients with Alopecia Areata: A Survey Study in the USA.

Introduction: Alopecia areata (AA) is an autoimmune condition that results in nonscarring hair loss. AA is comorbid with mental health disorders including anxiety and depression. This study aimed to evaluate the presence of post-traumatic stress disorder (PTSD) in relation to hair loss in patients with AA. Methods: A cross-sectional national survey was distributed using the National Alopecia Areata Foundation's (NAAF) email list. This study was approved by the Mass General Brigham Institutional Review Board. Participants were asked to complete the PTSD Checklist for the DSM-5 (PCL-5), a validated screening tool for PTSD in the context of their AA. Results: Of the 1,449 completed surveys (completion rate 79.6%), most respondents were female (83.8%) and white (76.6%) with an average age of 50.6 ± 15.6 years. Respondents had AA for an average of 17.7 ± 15.8 years, with 91.4% experiencing current active hair loss. A total of 33.9% of respondents screened positively for PTSD, with an average score of 48.8 ± 12.3 on the PCL-5 in participants who screened positively. Participants with alopecia totalis have the highest average PCL-5 score of 30.1 ± 19.2, followed by participants with alopecia universalis with an average score of 26.0 ± 19.9, and lastly patchy AA with an average score of 24.5 ± 18.3 (p = 0.003). Feelings of intrusion and avoidance were the predominant reported symptoms. Total PTSD scores were significantly higher in respondents who were younger and identified as Black or African American and Hispanic when compared to white and non-Hispanic respondents, respectively. Conclusion: These findings identify that one in 3 patients with AA in this cohort meet the screening criteria for PTSD specifically relating to their hair loss experience. These results further highlight the mental health comorbidities associated with AA and emphasize that these symptoms may persist even after hair regrowth. Limitations include the nonrandomized NAAF population with most participants being white females. Future studies should confirm these findings in other patient populations. Finally, respondent's baseline mental health was not assessed; therefore, a causal relationship between AA and PTSD cannot be deduced.

Tinea universalis due to Trichophyton indotineae in an adult male.

Tinea universalis is a condition when most of the anatomical sites of body are involved due to dermatophyte infection both in immunocompetent and immunocompromised individuals. Here we present a case of tinea universalis due to Trichophyton indotineae (T. indotineae) from India. This species has emerged recently. Earlier, it has been reported as Trichophyton mentagrophytes (T. mentagrophytes) and Trichophyton interdigitale (T. interdigitale). T. indotineae has been associated with outbreaks and epidemics of chronic, recalcitrant, and nonresponsive to terbinafine, in India and several other countries. The patient was prescribed Itraconazole (200 mg/day), Luliconazole cream topically and antihistamine at night, with marked improvement clinically. Easy availability and misuse of corticosteroids cream, as over-the-counter drug, should be discouraged.

Alopecia areata: What's new in the epidemiology, comorbidities, and pathogenesis?

BACKGROUND: Alopecia areata (AA) is a common, acquired, and nonscarring type of hair loss that affects people of every generation and is intractable in severe and relapsing cases. Patients with AA, especially those with greater scalp involvement, have poor health-related quality-of-life scores. PURPOSE: Following our previous review article in the April 2017 issue of the Journal of Dermatological Science, we aim to provide a pair of review articles on recent progress in multidisciplinary approaches to AA. MAIN FINDINGS: We found more than 1800 publications on AA from July 2016 to December 2022. CONCLUSIONS: In this review, we focused on the latest information on the epidemiology, comorbidities, and pathogenesis of AA.

Efficacy of Baricitinib in Patients with Various Degrees of Alopecia Areata Severity: Post-Hoc Analysis from BRAVE AA1 and BRAVE AA2.

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. Patients were subdivided by the degree of AA severity at baseline. RESULTS: Among the 855 patients treated with baricitinib 2 mg and 4 mg, improvements in scalp hair growth continued through to week 52. A superior response was observed in patients with a SALT score of 50-94 versus a score of 95-100. Patients on baricitinib 4 mg had a faster and higher response rate compared to baricitinib 2 mg. CONCLUSION: Across all degrees of severity for baricitinib 2 mg and 4 mg doses, the proportion of patients responding was yet to plateau up to week 52. Response to treatment was longer for patients with a baseline SALT score 95-100. Further studies are needed to analyze other parameters that may impact observed response rates.

Alopecia Universalis in an Elderly Chinese Man Induced by Sacubitril/Alisartan, a Novel Angiotensin Receptor-Neprilysin Inhibitor.

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.

Successful treatment of alopecia universalis with abrocitinib: a case report.

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. The therapeutic effects of JAK inhibitors for AA may involve downstream cytokines, such as IFN-γ and IL-15. Abrocitinib may be a promising therapeutic option for recalcitrant AU.

Janus kinase inhibitors for alopecia areata.

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.

Clinical and Genetic Aspects of Alopecia Areata: A Cutting Edge Review.

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. For instance, gene analysis of microRNAs can reveal the critical role of miRNAs in regulating gene expression, aiding in the understanding of cellular and organismal functional regulatory mechanisms. Furthermore, numerous studies have confirmed the existence of correlations between AA and other immune-related diseases. Examples include hyperthyroidism and rheumatoid arthritis. By understanding the interrelationships between AA and other immune diseases, we can further comprehend potential shared genetic foundations or pathogenic mechanisms among different diseases. Genetic research plays a crucial role in unraveling the pathogenesis of AA, as the identification of genetic variations associated with AA can assist in formulating more effective and targeted treatment strategies.

Alopecia universalis after injection of messenger RNA COVID-19 vaccine. A case report.

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.

Inherited Reticulate Pigmentary Disorders.

Reticulate pigmentary disorders (RPDs) are a group of inherited and acquired skin conditions characterized by hyperpigmented and/or hypopigmented macules. Inherited RPDs include dyschromatosis symmetrica hereditaria (DSH), dyschromatosis universalis hereditaria (DUH), reticulate acropigmentation of Kitamura (RAK), Dowling-Degos disease (DDD), dyskeratosis congenita (DKC), Naegeli-Franceschetti-Jadassohn syndrome (NFJS), dermatopathia pigmentosa reticularis (DPR), and X-linked reticulate pigmentary disorder. Although reticulate pattern of pigmentation is a common characteristic of this spectrum of disorders, the distribution of pigmentation varies among these disorders, and there may be clinical manifestations beyond pigmentation. DSH, DUH, and RAK are mostly reported in East Asian ethnicities. DDD is more common in Caucasians, although it is also reported in Asian countries. Other RPDs show no racial predilection. This article reviews the clinical, histological, and genetic variations of inherited RPDs.

Retyping and molecular pathology diagnosis of dyschromatosis universalis hereditaria.

Dyschromatosis universalis hereditaria (DUH) is characterized by diffuse symmetrically distributed hypopigmented macules mixed with hyperpigmentation. DUH is divided into three types by Online Mendelian inheritance in man (OMIM) that is, DUH1 (OMIM 127500), DUH2 (OMIM 612715) and DUH3 (OMIM 615402) according to the different linkage regions. Although each condition possesses corresponding phenotypic characteristics and the prognosis for each is somewhat different, these disorders are highly overlapped and difficult to differentiate in the clinical setting. Our latest study reveals a novel DUH subtype that presents a mild phenotype of pigmentation anomalies and is named PER3rs772027021 SNP related DUH or DUH4 by us, which make the DUH subtype can be further retyped. Heterozygous distribution or mosaic-like distribution of melanin is a newly discovered pathological features that is uniquely demonstrated in the affected layers of DUH1 and DUH4 patients. In this review, DUH is further divided into four subtypes according the causative genes and their mutational sites, and the mutation regions described in the previous reports. To make an accurate diagnosis, we suggest that Sanger sequencing or the target region sequencing (TRS) to the candidate causative genes related melanogenesis may be the most effective and convenient method of clinical diagnosis or/and prenatal diagnosis for DUH and DUH-like patients. More importantly, heterozygous distribution or mosaic-like distribution of melanin can be utilized for differential diagnosis of DUH. We also investigate the underlying molecular mechanism to form mosaic-like melanin in the affected layers of hyper- and/or hypo-pigmented macules from DUH1 and DUH4 patients. This review provides a molecular and pathological delineation of four types of DUH and aims to establish a concise diagnostic strategy to allow clinical dermatologists to make an accurate diagnosis.

Incidence Rates of Infections, Malignancies, Thromboembolism, and Cardiovascular Events in an Alopecia Areata Cohort from a US Claims Database.

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. This real-world, US claims-based study aimed to estimate the incidence of events in patients with AA compared with matched patients without AA. METHODS: Patients aged ≥ 12 years enrolled in the Optum Clinformatics Data Mart database from 1 October 2016 to 30 September 2020, with ≥ 2 AA diagnosis codes were included in the AA cohort. Patients without AA were age-, sex-, and race-matched 3:1 to patients with AA. Baseline comorbidities were evaluated during the 12-month period pre-index date. Incident cases of serious/herpes infections, malignancies, major adverse cardiovascular events (MACE), and thromboembolic events were evaluated post-index date. Data are presented using descriptive statistics, proportional percentages, frequencies, and IRs (calculated with 95% CI). RESULTS: Overall, 8784 patients with AA, 599 of whom had AT/AU, were matched to 26,352 patients without AA. IRs per 1000 person-years among the AA and non-AA cohorts, respectively, were 18.5 and 20.6 for serious infections, 19.5 and 9.7 for herpes simplex infections, 7.8 and 7.6 for herpes zoster infections, 12.5 and 11.6 for primary malignancies, 16.0 and 18.1 for MACE, and 4.9 and 6.1 for venous thromboembolisms. Compared with patients with non-AT/AU AA, patients with AT/AU largely had higher IRs for most baseline comorbidities and outcome events evaluated. CONCLUSION: Patients with AA had a higher IR of herpes simplex infection than the matched non-AA cohort. Patients with AT/AU generally had higher rates of outcome events than patients without AT/AU.

A retrospective study on the clinical characteristics and prognosis of alopecia totalis and universalis: An update on prognosis.

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. The authors retrospectively reviewed patients diagnosed with AT and AU from 2006 to 2017 in a single institution. Of the 419 patients, the mean age at first episode was 22.9 years, and 24.6% had early onset (≤13 years). During follow-up, 53.9% had more than 50% hair growth, and 19.6% of patients showed >90% hair growth. Among patients who showed >50% improvement, 36.7% had no recurrence. In early studies conducted in the 1950s and 1960s, the chance of full hair regrowth was reported to be <10%. In our study, patients with >90% improvement in AT and AU accounted for 19.6% of patients. The authors provide an update on data regarding the prognoses of AT and AU.
