INTRODUCTION
Cyclosporine is commonly used in treatment for alopecia areata. It can be administered as a monotherapy or in combination with systemic corticosteroids, with various outcomes.
METHODS
Efficacy of cyclosporine with and without systemic corticosteroids for alopecia areata was evaluated by a systematic review. Cochrane, EBSCOhost, Pubmed, Scopus and Web of Science databases were searched. Only studies published before January 2020 were included.
RESULTS
A total of 2104 studies were initially examined, of which 14 were eligible for the systematic review. Among 340 reported cases, 213 had focal, multifocal or ophiasis form of alopecia areata, 60 were diagnosed with alopecia totalis and 67 with alopecia universalis. The mean response rate in the whole group of patients at the end of treatment was 65.00% (221/340; range 25-100%). Hair regrowth rate was higher in the group with cases of alopecia areata limited to scalp (124/165; mean 75.15%; range 40-100%) than in the cases with alopecia totalis (30/46; mean 65.22%; range 25-100%) or alopecia universalis (24/52; mean 46.15%; range 25-100%). The combined therapy with systemic corticosteroids was superior to the monotherapy (152/219; mean 69.41%; 0-80% vs. 69/121; mean 57.02%; range 6.67-100%) and had a lower recurrence rate (39/108; mean 36.11% vs. 34/46; mean 73.91%, respectively). The combined treatment with methylprednisolone was significantly more effective when compared to the cyclosporine monotherapy (124/183; mean 67.76%; range 0-80% vs. 69/121; mean 57.02%; range 6.67-100%). The mean time of treatment was 6.75 months (range 2-36).
LIMITATIONS
Limitations of our study were the retrospective character of included studies, differences in doses of prescribed drugs, and duration of the treatment and follow-up times.
CONCLUSION
Cyclosporine in combination with oral systemic corticosteroids is more effective than in monotherapy for severe alopecia areata.

INTRODUCTION
Alopecia areata (AA) is a non-scarring hair loss condition, subclassified into AA, alopecia universalis, and alopecia totalis. There are indications that people with AA experience adverse psychosocial outcomes, but previous studies have not included a thorough meta-analysis and did not compare people with AA to people with other dermatological diagnoses. Therefore, the aim of this systematic review and meta-analysis was to update and expand previous systematic reviews, as well as describing and quantifying levels of anxiety, depression, and quality of life (QoL) in children and adults with AA.
METHODS
A search was conducted, yielding 1,249 unique records of which 93 were included.
RESULTS
Review results showed that people with AA have higher chances of being diagnosed with anxiety and/or depression and experience impaired QoL. Their psychosocial outcomes are often similar to other people with a dermatological condition. Meta-analytic results showed significantly more symptoms of anxiety and depression in adults with AA compared to healthy controls. Results also showed a moderate impact on QoL. These results further highlight that AA, despite causing little physical impairments, can have a significant amount on patients' well-being.
DISCUSSION
Future studies should examine the influence of disease severity, disease duration, remission and relapse, and medication use to shed light on at-risk groups in need of referral to psychological care.

Meta-Analysis
IMPORTANCE
Contact immunotherapy with diphenylcyclopropenone or squaric acid dibutyl ester is a preferred treatment for severe alopecia areata; however, the defined criteria for therapeutic hair regrowth and regrowth rate have been highly heterogeneous across studies.
OBJECTIVE
To summarize the clinical outcomes of contact immunotherapy for alopecia areata according to standardized criteria for therapeutic hair regrowth and several prognostic factors.
DATA SOURCE
A database search of MEDLINE, Embase, and Cochrane Library was performed for articles published before November 20, 2017, using the search terms areata, totalis, universalis, sensitizer, sensitization, immunotherapy, DPCP, diphenylcyclopropenone, diphencyprone, SADBE, and squaric.
STUDY SELECTION
Clinical trials or observational studies that investigated contact immunotherapy for alopecia areata and subgrouped the disease into patchy alopecia or alopecia totalis/universalis and reported their hair regrowth rates were included, whereas studies that investigated combination therapy or nonconventional protocol and case series or reviews were excluded.
DATA EXTRACTION AND SYNTHESIS
The following data were extracted from each of the studies included in this meta-analysis: study year and setting, sensitizer type, study population, study population composition by disease subtype, defined criteria for therapeutic hair regrowth, and regrowth rate of contact immunotherapy. The incidence of adverse effects and recurrence rate were also recorded. A random effects model was used for data synthesis because of the expected high heterogeneity of the included studies.
MAIN OUTCOMES AND MEASURES
The main outcome was therapeutic hair regrowth rate according to the 4-grade criteria for therapeutic regrowth. Secondary outcomes included incidence of treatment-related adverse effects and recurrence rate.
RESULTS
Forty-five studies comprising 2227 patients were analyzed. The overall rate of any hair regrowth was 65.5% among patients with alopecia areata (74.6% in the patchy alopecia and 54.5% in the alopecia totalis/universalis subgroups). However, the complete regrowth rate was 32.3% (24.9% in the patchy alopecia and 32.3% in the alopecia totalis/universalis subgroups). Disease extent of 50% or greater (odds ratio [OR], 3.05; 95% CI, 2.26-4.12), atopic history (OR, 1.61; 95% CI, 1.03-2.50), and nail involvement (OR, 2.06; 95% CI. 1.26-3.36) were associated with poorer therapeutic outcome. Recurrence rates were 38.3% among patients receiving maintenance treatment and 49.0% among those not receiving maintenance treatment.
CONCLUSIONS AND RELEVANCE
Various factors were associated with the clinical outcomes of contact immunotherapy for alopecia areata, with significant differences in hair regrowth rates according to the level of expected therapeutic regrowth. Quantitative summarization may improve patient education and lead to better therapeutic adherence and outcomes.
