Hammadi AA, Parmar NV, Farghaly M, Dallal SA, Zayed MWA, Ebeid F, Subramanyam K, Ramachandrachar BC, Ahmed HM. A retrospective analysis of disease epidemiology, comorbidities, treatment patterns, and healthcare resource utilization of alopecia areata in the United Arab Emirates using claims database. J Dermatol 2024; 51:1157-1171. [PMID: 39051178 DOI: 10.1111/1346-8138.17381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 05/29/2024] [Accepted: 06/27/2024] [Indexed: 07/27/2024]
Abstract
Alopecia areata (AA) is an autoimmune disorder that manifests as nonscarring hair loss and imposes a substantial disease burden. The current study, using an e-claims database, assesses the disease burden, comorbidities, treatment patterns, specialties involved in the diagnosis of AA, healthcare resource utilization (HCRU), and associated costs in privately insured patients with AA in Dubai, United Arab Emirates. The retrospective longitudinal secondary study was conducted using Dubai Real-World Database e-claims data during 01 January 2014 to 30 June 2022. Patients with at least one diagnosis claim of AA during the index period (01 January 2015-30 June 2021) with continuous enrollment (one or more AA/non-AA claim in the post-index period) were included in the analysis. The patients were stratified into subcohorts based on diagnosis code and treatment patterns, as mild, moderate-to-severe, and others. Demographics, comorbidities, treatment patterns, specialists visited, and HCRU were assessed. The study included 11 851 patients with AA (mean age: mild: 37 years; moderate-to-severe: 36 years), with a male predominance (mild: 77.6%; moderate-to-severe: 60.8%). The most prevalent comorbidities in the moderate-to-severe AA subcohort were autoimmune and T-helper 2-mediated immune disorders, including contact dermatitis and eczema (62.1%), atopic dermatitis (36.1%), and asthma (36.1%). Most patients consulted dermatologists for treatment advice (mild AA: 87.4%; moderate-to-severe AA: 47.7%) and, notably, within 1 day of AA diagnosis. Topical steroids were frequently prescribed across cohorts, regardless of disease severity. Analysis of comorbidities among patients with AA indicated an additional HCRU burden among these subsets of patients. The median disease-specific HCRU cost was higher for psychological comorbidities versus autoimmune and T-helper 2-mediated immune disorders (US $224.99 vs US $103.70). There is a substantial disease and economic burden in patients with AA and associated comorbid conditions; therefore, investing in novel therapies that target the underlying autoimmune pathway may address the gap in effective management of AA.

Kwon O, Wallace M, Messina P, Szende A, Choi JW, Newson RS, Koo DH, Lee JH. Treatment patterns and healthcare resource utilization among patients with alopecia areata: A real-world chart review in South Korea. J Dermatol 2024. [PMID: 39044416 DOI: 10.1111/1346-8138.17380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 05/28/2024] [Accepted: 06/27/2024] [Indexed: 07/25/2024]
Abstract
Alopecia areata (AA) is a clinically heterogeneous, immune-mediated, non-scarring hair loss disorder. This real-world chart review sought to characterize treatment patterns and healthcare resource use among patients with severe AA in South Korea. A web-based chart review of 40 dermatologists was conducted in which the medical charts of 151 adult patients diagnosed with severe AA between May 2019 and April 2021 were reviewed. Anonymized data on patient characteristics, treatment patterns, healthcare resource use, and clinical outcomes were extracted from the date of severe disease diagnosis until the date of data collection (September-November 2022). Sixty-six percent of patients were diagnosed with severe disease at initial presentation, while 34% were re-classed to severe during the disease course. Mean estimated patient age at the time of diagnosis of severe AA was 37.1 (range 22-68) years. Fifty-three percent of patients were male. Most patients (93.4%) received pharmacological treatment for their condition; 45.5% received ≥2 lines of treatment with a mean duration of 24 months. First-line treatment discontinuation due to lack of efficacy occurred in 46.0% of cases. Hair regrowth occurred in 71.0% of patients, 59.2% of whom experienced major regrowth (≥60%) during the follow-up period. Median (95% confidence interval) time to regrowth was 13.7 (11.0-20.6) months. Treatment visit rates per person-year ranged from two (phototherapy) to 10 (topical treatment), dermatologist visits occurred at a rate of 12.9 per person-year and 6.0% of patients were hospitalized due to alopecia areata. The majority of hospitalizations were related to treatment and occurred in patients who received pulse systemic corticosteroid therapy. The patient and economic burden of AA in South Korea is high and there remains a critical unmet need among patients with severe AA with respect to the effectiveness of commonly used treatment strategies.

Abstract
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. Alopecia areata was identified based on having at least 1 diagnosis of International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code L63.x. Patients were required to have at least 365 days of continuous health plan enrollment before and after the cohort entry date. Patients were required to be free of AA diagnosis codes 365 days before the cohort entry date. Statistical analyses were conducted between 2019 and 2023. Main Outcomes and Measures Main outcomes were treatment patterns for all patients with AA and subgroups of (1) patients with AT or AU and (2) those cared for by a dermatologist on the cohort entry date. Longitudinal therapy course during the first year after the diagnosis was also examined. Results The study cohort consisted of 45 483 individuals (mean [SD] age, 43.8 [14.2] years; 29 903 [65.7%] female). During the year of follow-up, 30 217 patients (66.4%) received at least 1 AA treatment. The most common treatments were intralesional (19 014 [41.8%]), topical (18 604 [40.9%]), intramuscular (17 328 [38.1%]), and oral (9378 [20.6%]) corticosteroids. Compared with patients without AT or AU, patients with AT or AU a lower frequency of intralesional steroid (359 [11.1%] vs 18 655 [44.1%], P < .001) and higher frequency of topical corticosteroid (817 [25.4%] vs 17 787 [42.1%], P < .001) use. Almost half of patients (21 489 [47.2%]) received no treatment on the day of diagnosis. By 12 months, 32 659 (71.8%) were not receiving any treatment, making no treatment the largest study group. Conclusions and Relevance In this large cohort study of commercially insured individuals, corticosteroids were the most commonly used treatment for adults with AA between 2015 and 2020. At 365 days after diagnosis, more than two-thirds of patients were no longer receiving any AA treatment. Further studies are needed to understand the reasons for the absence of treatment.

Abstract
BACKGROUND Alopecia areata (AA) is a complex autoimmune condition resulting in nonscarring hair loss. In recent years, many studies have provided new evidence on comorbid diseases present in patients with AA. However, some studies have conflicting results, and analyses conducting a comprehensive approach are lacking. OBJECTIVE The aim of our study was to provide an updated systematic review and meta-analysis of medical comorbidities associated with AA. METHODS We searched PubMed, Embase, and Web of Science for case-control, cross-sectional, and cohort studies investigating medical comorbidities in AA published from inception through 1 February 2023. RESULTS We screened 3428 abstracts and titles and reviewed 345 full text articles for eligibility. Ultimately, 102 studies were analyzed, comprising 680,823 patients with AA and 72,011,041 healthy controls. Almost all included studies (100 of 102 studies) were of satisfactory to high quality (Newcastle-Ottawa scale score ≥ 4). Among patients with AA, comorbidities with the highest odds ratios (OR) compared with healthy controls and data available from more than one study included vitamin D deficiency (OR 10.13, 95% CI 4.24-24.20), systemic lupus erythematous (OR 5.53, 95% CI 3.31-9.23), vitiligo (OR 5.30, 95% CI 1.86-15.10), metabolic syndrome (OR 5.03, 95% CI 4.18-6.06), and Hashimoto's thyroiditis (OR 4.31, 95% CI 2.51-7.40). AA may be a protective factor for certain disorders, for which the AA group had lower odds compared with healthy controls, such as irritable bowel syndrome (OR 0.38, 95% CI 0.14-0.99) and colorectal cancer (OR 0.61, 95% CI 0.42-0.89). CONCLUSION These findings corroborate and contextualize the risks across comorbidities for patients with AA. Further work should be done to identify the underlying pathophysiology and understand appropriate screening criteria.

Abstract
Alopecia area (AA) is a common autoimmune disorder, characterized by hair loss. Although its impact on quality of life is fairly well understood, studies on the economic impact of AA are limited. The aim of this study was to quantify the personal and nationwide economic burden of AA in Japan. Data were drawn from the Adelphi AA Disease Specific Programme (DSP)™, a real-world, cross-sectional survey with retrospective data collection, of Japanese physicians and patients with AA. The study was conducted in 2021, before the approval of Janus kinase inhibitors for AA. Physicians and their consulting AA patients completed questionnaires regarding disease severity, treatment, and AA-related costs. The Work Productivity and Activity Impairment questionnaire was used to evaluate the impact of AA on patients' work and activity. Nationwide estimates of cost and productivity loss were extrapolated from collected patient data. A total of 50 physicians provided data on 235 patients; 58.7% were female, mean ± SD age was 41.1 ± 11.8 years, and mean physician-estimated scalp hair loss was 40.4% ± 30.2%. Prescription medication use was high (92.3% of patients), but the use of over-the-counter medication was low, at 8.7%. Mean cost to patients for medication was ¥ 4263 (US$ 32.42) per month. Productivity while at work (presenteeism) was significantly impaired (23.9% ± 25.7%), but absenteeism was low (0.9% ± 2.8%). The total nationwide cost of AA was estimated at 112.7 billion yen (US$ 857 million), of which 88.1 billion yen (78.2%) was due to productivity loss. Over 2 million days per year of activity time were estimated to be lost due to AA. Thus, despite not being a physically limiting disease, AA has a significant impact in terms of cost and time, both on a personal and national level. These data highlight the need for more targeted interventions to reduce the effects of AA on the Japanese economy.

Abstract
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. Corticosteroids were the most common first-line (1L) and second-line (2L) treatments. The mean time from diagnosis of alopecia areata to initiation of 1L treatment was 2.2 days for adults and 2.6 days for adolescents; mean 1L duration was 76.9 and 64.3 days, respectively. For adults (57.5%) and adolescents (59.7%) with 2L therapy, the mean time from 1L discontinuation to 2L initiation was 57.2 and 53.6 days, respectively; the mean duration of 2L treatment was 55.5 and 50.1 days, respectively. More patients with vs without alopecia totalis or alopecia universalis initiated 2L therapy (adults: 71.9% vs 56.8%; adolescents: 71.4% vs 58.9%). The proportion of days covered during the first year post-diagnosis was 36.7% (adults) and 34.1% (adolescents). These results highlight the substantial disease burden of alopecia areata and a need for more effective treatments.

Abstract
Alopecia areata (AA) is an autoimmune disease with a complex pathophysiology resulting in nonscarring hair loss in genetically susceptible individuals. We aim to provide health care decision makers an overview of the pathophysiology of AA, its causes and diagnosis, disease burden, costs, comorbidities, and information on current and emerging treatment options to help inform payer benefit design and prior authorization decisions. Literature searches for AA were conducted using PubMed between 2016 and 2022 inclusive, using search terms covering the causes and diagnosis of AA, pathophysiology, comorbidities, disease management, costs, and impact on quality of life (QoL). AA is a polygenic autoimmune disease that significantly impacts QoL. Patients with AA face economic burden and an increased prevalence of psychiatric disease, as well as numerous systemic comorbidities. AA is predominantly treated using corticosteroids, systemic immunosuppressants, and topical immunotherapy. Currently, there are limited data to reliably inform effective treatment decisions, particularly for patients with extensive disease. However, several novel therapies that specifically target the immunopathology of AA have emerged, including Janus kinase (JAK) 1/2 inhibitors such as baricitinib and deuruxolitinib, and the JAK3/tyrosine kinase expressed in hepatocellular carcinoma (TEC) family kinase inhibitor ritlecitinib. To support disease management, a disease severity classification tool, the Alopecia Areata Severity Scale, was recently developed that evaluates patients with AA holistically (extent of hair loss and other factors). AA is an autoimmune disease often associated with comorbidities and poor QoL, which poses a significant economic burden for payers and patients. Better treatments are needed for patients, and JAK inhibitors, among other approaches, may address this tremendous unmet medical need.

Abstract
BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by nonscarring hair loss. AA frequently co-occurs with other inflammatory autoimmune conditions, presenting a significant clinical burden. OBJECTIVE: To compare the burden of illness, direct and indirect costs in adult patients with AA vs atopic dermatitis (AD). METHODS: This retrospective cohort study used US administrative claims data from the Merative MarketScan Commercial Claims and Encounters Database to compare commercially insured adults with AA to those with AD. Patients with an AA diagnosis between January 2017 and September 2019 were propensity score matched to patients with AD. Comorbidity burden, medication use, health care resource utilization, health care costs, and indirect costs during a 12-month follow-up period were compared between cohorts. RESULTS: Overall, 25,446 adult patients with AA were selected for the matched analysis with the AD cohort. Patients with AA generally had lower comorbidity burden than patients with AD; mean Deyo-Charlson Comorbidity Index scores were 0.36 (SD = 0.99) and 0.39 (SD = 0.92), for AA and AD, respectively (P = 0.007). Patients with AA had significantly lower proportions of allergic rhinitis, asthma, pruritus, skin infections, and urticaria, but higher proportions of thyroid disease, when compared with patients with AD (all P < 0.001). A smaller proportion of patients with AA had prescriptions for topical (45.3% vs 64.8%; P < 0.001) and oral (20.3% vs 29.6%; P < 0.001) corticosteroids and antianxiety and/or antidepressants (24.7% vs 29.7%; P < 0.001), but a significantly larger proportion for intralesional corticosteroids (triamcinolone) (49.6% vs 21.7%; P < 0.001), compared with patients with AD. Despite a lower comorbidity burden and generally less medication usage in patients with AA, total all-cause health care costs did not significantly differ between the AA and AD cohorts ($10,705 vs $10,816; P = 0.712), and outpatient costs were higher in patients with AA ($6,297 vs $5,859; P = 0.014). Female patients with AA had significantly greater costs for both outpatient and outpatient pharmacy when compared with female patients with AD. Patients with AA were more likely to have a claim for long-term disability (0.6% vs 0.3%; P = 0.001) and higher long-term disability-associated indirect costs ($73 [SD = $1,442] vs $25 [SD = $774]; P = 0.004) compared with patients with AD. CONCLUSIONS: We found similar total health care costs in patients with AA and AD, despite a lower proportion of comorbidities and prescription use in patients with AA. Outpatient costs were also significantly higher overall in patients with AA. Although often dismissed as a cosmetic condition, AA, an autoimmune disease, has a similar level of medical expenditure as AD. DISCLOSURES: This study was funded by Eli Lilly and Company.

Abstract
Importance Alopecia areata (AA) is characterized by nonscarring hair loss of the scalp, face, and/or body. Alopecia totalis (AT) and alopecia universalis (AU) involve complete loss of the scalp and body hair, respectively. The epidemiology of AA in the US remains unclear, having previously been extrapolated from older studies that were limited to specific geographic areas or clinical settings, or from self-reported data. Objective To estimate the annual prevalence and incidence of AA and AT and/or AU (AT/AU) in the US. Design, Setting, and Participants This retrospective, population-based cohort study was conducted from January 2016 to December 2019 and included enrollees in the IBM MarketScan Commercial Claims and Encounters and Medicare Supplemental databases and their dependents, with plan enrollment during each study calendar year and the year prior. Exposures Prevalent cases were identified by 1 or more claims for AA or AT/AU (International Statistical Classification of Diseases, Tenth Revision, Clinical Modification [ICD-10-CM] codes L63.x, L63.0, L63.1) during each year of interest or the year prior. Incident cases were identified by 1 or more claims for AA or AT/AU during a specific year and no diagnosis the year prior. Main Outcomes and Measures Annual incidence and prevalence rates were calculated and stratified by age, sex, and region. National employer-sponsored insurance population estimates were obtained using population-based weights. Results Among eligible patients (2016: n = 18 368 [mean (SD) age, 40.6 (17.9) years; 12 295 women (66.9%)]; 2017: n = 14 372 [mean (SD) age, 39.6 (17.7) years; 9195 women (64.0%)]; 2018: n = 14 231 [mean (SD) age, 38.9 (17.3) years; 8998 women (63.2%)]; 2019: n = 13 455 [mean (SD) age, 39.1 (17.4) years; 8322 women (61.9%)]), AA prevalence increased from 0.199% (95% CI, 0.198%-0.200%) in 2016 to 0.222% (95% CI, 0.221%-0.223%) in 2019. Roughly 5% to 10% of prevalent and incident cases of AA were AT/AU. The prevalence of AT/AU increased from 0.012% (95% CI, 0.012%-0.013%) to 0.019% (95% CI, 0.018%-0.019%) from 2016 to 2019. Incidence of AA per 100 000 person-years ranged from 87.39 (95% CI, 86.84-87.96) in 2017 to 92.90 (95% CI, 92.35-93.45) in 2019. Incidence of AT/AU ranged from 7.09 (95% CI, 6.94-7.25) in 2017 to 8.92 (95% CI, 8.75-9.09) in 2016. Prevalence and incidence of AA and AT/AU were higher among female vs male individuals, adults vs children and adolescents, and in the Northeast vs other regions. Conclusions and Relevance The results of this cohort study suggest that these recent AA prevalence and incidence estimates could help improve current understanding of the disease burden. Further research is warranted to elucidate subpopulation differences and trends in AA in the broader US population.

The burden of alopecia areata: A scoping review focusing on quality of life, mental health and work productivity. J Eur Acad Dermatol Venereol 2023; 37:1490-1520.

Abstract
Alopecia areata (AA) is a common inflammatory autoimmune disease of the hair which can have a significant negative impact on quality of life (QoL), mental health and productivity. The aim of this scoping review is to elucidate the burden of AA focusing on these three realms. Inclusion criteria included all original manuscripts with no restriction on study type or statistical method written in English (or having an English abstract). For QoL 40 articles were included, 85 for psychiatric comorbidities, and 9 for work/school absenteeism/presenteeism mostly consisting of cross-sectional and observational cohort studies. QoL impairment was detected in over 75% of patients and up to one-third reported extremely severe QoL impairments. Specific QoL dimensions with the greatest impact were embarrassment, social functioning, as well as shopping and/or housework. Cross-sectional studies assessing the psychological burden of adult patients with AA found that the presence of signs of anxiety and/or depression ranged from 30% to 68% and affected all age groups. Rates of work absenteeism and unemployment were significantly higher in AA patients compared to healthy controls. Up to 62% reported making major life decisions including relationships, education and career based on their AA. Additionally, the extensive camouflage techniques and time lost from work led to a strong financial burden for patients and the numerous physician visits added to the healthcare costs. The overall impact of AA stretches much further than simply being an aesthetic concern and can negatively impact every part of an individual's life. An individualized approach and effective treatments will help reduce the psychosocial consequences and distress and return patients to their normal state of health.
