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.

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.

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.

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.

The frequency of fatty liver in patients with alopecia areata: A case-control study.

BACKGROUND: Alopecia areata (AA) is an immune-mediated nonscarring hair loss disorder with multiple subtypes, including alopecia universalis (AU). Previous studies have shown a link between serum lipid profile and alopecia. We aimed to investigate the frequency of fatty liver in patients with AU and patchy alopecia areata (PAA) compared to a control group. METHODS: This case-control study included patients with AU and PAA referred to a dermatology clinic from September 23, 2019 to September 23, 2020. A group of individuals without hair loss disorders attending the same clinic were selected as controls. Participants' general information, including age, sex, weight, height, and waist circumference (WC), was recorded. Body mass index (BMI) was calculated for all participants. Also, hyperlipidemia and statin use were noted and liver enzymes were evaluated. For AU and PAA patients, disease duration and the Severity of Alopecia Tool (SALT) score were also recorded. Then, all subjects underwent ultrasound to assess fatty liver and its grade. RESULTS: Overall, 32 patients were included in each group. All three groups were comparable in age, sex, weight, height, BMI, WC, hyperlipidemia, abnormal liver enzymes, and statin use. Disease duration and SALT score were significantly higher in the AU than in the PAA group (p = 0.009 and p < 0.001, respectively). The frequency of fatty liver was the highest in AU patients (40.6%), followed by 34.4% in PAA patients, and 21.9% in controls (p = 0.263). This was also the case for grade-1 fatty liver, while grade-2 was more common in PAA patients, and grade-3 was only observed in one patient from the AU group (p = 0.496). CONCLUSIONS: Fatty liver was more frequent in AU and PAA patients than controls, without statistically significant differences. There might be an association between fatty liver and AA, particularly the AU subtype.

Assessing Patient's Values When Selecting Treatments for Alopecia Areata: A Cross-Sectional Survey Study.

Introduction: Alopecia areata (AA) is an autoimmune condition that results in nonscarring hair loss. There is currently only one Food and Drug Administration (FDA)-approved treatment for AA; as a result, a wide range of treatments are commonly administered. This study aimed to determine how patients with AA prioritize treatment characteristics when choosing a therapy. 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 rank the importance of five treatment domains. Results: Of the 1,074 completed surveys (completion rate 77.4%), most respondents were female (85.4%) and white (77.8%) with an average age of 49.3 ± 15.4 years. Respondents had AA for an average of 17.7 ± 15.4 years, with 90.0% experiencing current active hair loss. 95.6% of respondents considered the treatment's ability to achieve hair regrowth as important, 93.9% listed the availability of information about the treatment (e.g., via doctor or online) as important, 89.1% ranked the treatment side effects as important, 75.7% the cost, and 68.0% the convenience of use. A sub-analysis was performed examining responses between respondents who identify as white versus nonwhite, which showed that while the order of importance was the same between groups, a significantly larger proportion of nonwhite respondents attributed higher importance to cost (white: 73.8%, nonwhite: 82.4%; p = 0.006) and convenience (white: 65.3%, nonwhite: 77.3%; p < 0.001) than their white counterparts. Discussion/Conclusion: These findings identify key domains that can serve as a starting point in shared decision-making between patients and physicians. This knowledge can streamline dermatologist delivery of key information and highlight areas of improvement for future therapeutics. Limitations include the nonrandomized NAAF population with most participants being white females. Future studies should confirm these findings in other patient populations.

Hydroxychloroquine for granuloma annulare: A case report on secondary hair growth in alopecia universalis.

Alopecia areata is an autoimmune disease resulting in non-scarring hair loss. Alopecia areata can progress to become alopecia totalis (loss of hair from the entire scalp) or alopecia universalis (loss of hair form the entire body), with the progression estimated to range from 7% to 30%. There are no universally proven therapies that both induce and sustain remission, and furthermore, the course of alopecia areata tends to be unpredictable, with ~80% of patients achieving spontaneous remission within 1 year. We herein present the case of a 61-year-old female who presented with a 20-year history of alopecia universalis, and biopsy confirmed widespread granuloma annulare. Hydroxychloroquine was initiated to treat her granuloma annulare, with subsequent significant hair regrowth on her scalp, eyebrows, eyelashes, and arms. A review of the literature is presented showing that hydroxychloroquine has variable success in treatment of alopecia areata, alopecia totalis, and alopecia universalis.
