Meta-Analysis Review
BACKGROUND
JAK inhibitors treat various autoimmune diseases, but an updated systematic review in treating alopecia areata is currently lacking.
OBJECTIVE
Evaluate the specific efficacy and safety of JAK inhibitors in alopecia areata by systematic review and meta-analysis.
METHODS
Eligible studies in PubMed, Embase, Web of Science, and Clinical Trials up to May 30, 2022, were searched. We enrolled in randomized controlled trials and observational studies of applying JAK inhibitors in alopecia areata.
RESULTS
6 randomized controlled trials with 1455 patients exhibited SALT (odd ratio [OR], 5.08; 95% confidence interval [CI], 3.49-7.38), SALT (OR, 7.40; 95% CI, 4.34-12.67) and change in SALT score (weighted mean difference [WSD], 5.55; 95% CI, 2.60-8.50) compared to the placebo. The proportion of 26 observational studies with 563 patients of SALT was 0.71(95% CI, 0.65-0.78), SALT was 0.54(95% CI 0.46-0.63), SALT was 0.33(95% CI, 0.24-0.42), and SALT score (WSD, -2.18; 95% CI, -3.12 to -1.23) compared with baseline. Any adverse effects occurred in 921 of 1508 patients; a total of 30 patients discontinued the trial owing to adverse reactions.
LIMITATIONS
Few randomized controlled trials met the inclusion criteria and insufficiency of eligible data.
CONCLUSION
JAK inhibitors are effective in alopecia areata, although associated with an increased risk.

Review
OBJECTIVES
Biological medications have been used with an increasing frequency to treat rheumatological diseases. Autoimmune events can be induced by these drugs, such as psoriasiform lesions, alopecia, lupus and, vasculitis, which more often affects the skin (small-sized vessels) and eventually other organs. In this review, we describe the clinical profile of patients with vasculitis induced by the main biological agents used in rheumatology.
PATIENTS AND METHODS
We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The PubMed database was used for searching eligible articles. We included case reports, case series, and letter to the editor of patients on anti-tumor necrosis factor-alpha (anti-TNF-a) molecules, as well as tocilizumab, ustekinumab, secukinumab, rituximab, and abatacept, who had vasculitis induced by these agents.
RESULTS
Eighty-one articles were included for final analysis (n=89). Twenty-seven patients were using infliximab, 20 adalimumab, 18 etanercept, seven secukinumab, four certolizumab, four rituximab, three golimumab, three ustekinumab, two abatacept, and one tocilizumab. Unspecific leukocytoclastic vasculitis (LCV) was the most common type of vasculitis (n=37), followed by anti-neutrophil cytoplasmic antibody (ANCA)- associated vasculitis (n=16). The medication was replaced with another biological molecule in 23 cases, with only four relapses. In six cases, the biological was maintained, but vasculitis worsened/persisted in one case, being necessary drug removal.
CONCLUSION
Infections, infusion reaction, cancer, and autoimmune events are well-known side effects of biological therapy. This review demonstrates that vasculitis is another adverse effect of this type of therapy, particularly the anti-TNF-a molecules, and LCV the most reported type of vasculitis.

Review
BACKGROUND
Probiotics are intellectually rewarding for the discovery of their potential as a source of functional food. Investigating the economic and beauty sector dynamics, this study conducted a comprehensive review of scholarly articles to evaluate the capacity of probiotics to promote hair growth and manage dandruff.
METHODS
We used the PRISMA 2020 with Embase, Pubmed, ClinicalTrials.gov, Scopus, and ICTRP databases to investigate studies till May 2023. Meta-analyses utilizing the random effects model were used with odds ratios (OR) and standardized mean differences (SMD).
RESULT
Meta-analysis comprised eight randomized clinical trials and preclinical studies. Hair growth analysis found a non-significant improvement in hair count (SMD = 0.32, 95 % CI -0.10 to 0.75) and a significant effect on thickness (SMD = 0.92, 95 % CI 0.47 to 1.36). In preclinical studies, probiotics significantly induced hair follicle count (SMD = 3.24, 95 % CI 0.65 to 5.82) and skin thickness (SMD = 2.32, 95 % CI 0.47 to 4.17). VEGF levels increased significantly (SMD = 2.97, 95 % CI 0.80 to 5.13), while IGF-1 showed a non-significant inducement (SMD = 0.53, 95 % CI -4.40 to 5.45). For dandruff control, two studies demonstrated non-significant improvement in adherent dandruff (OR = 1.31, 95 % CI 0.13-13.65) and a significant increase in free dandruff (OR = 5.39, 95 % CI 1.50-19.43). Hair follicle count, VEGF, IGF-1, and adherent dandruff parameters were recorded with high heterogeneity. For the systematic review, probiotics have shown potential in improving hair growth and controlling dandruff through modulation of the immune pathway and gut-hair axis. The Wnt/β-catenin pathway, IGF-1 pathway, and VEGF are key molecular pathways in regulating hair follicle growth and maintenance.
CONCLUSIONS
This review found significant aspects exemplified by the properties of probiotics related to promoting hair growth and anti-dandruff effect, which serve as a roadmap for further in-depth studies to make it into pilot scales.

Meta-Analysis
IMPORTANCE
Two recent meta-analyses reported a high prevalence of both anxiety and depression in patients with alopecia areata (AA), as well as a positive association of AA with anxiety and depression, without distinguishing between disorders and symptoms. Yet, depression and anxiety can manifest either as symptoms identified in questionnaires or as specific diagnoses defined by Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision criteria.
OBJECTIVE
To perform a large meta-analysis separating the prevalence of depressive and anxiety disorders from that of depressive and anxiety symptoms in patients with AA.
DATA SOURCES
PubMed, ScienceDirect, the Cochrane Library, Embase, and PsycINFO databases were searched from inception through August 1, 2020.
STUDY SELECTION
Studies that contained data on the prevalence of depressive or anxiety disorders or symptoms were included.
DATA EXTRACTION AND SYNTHESIS
The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines were used. Pooled prevalence was calculated with a random effects model meta-analysis that took into account between- and within-study variability. Meta-regressions were used to study the association between variations in prevalence and study characteristics.
MAIN OUTCOMES AND MEASURES
The prevalence of depressive and anxiety disorders and symptoms in patients with AA.
RESULTS
Thirty-seven articles (29 on depression and 26 on anxiety) that met the inclusion criteria were identified. By distinguishing between disorders and symptoms, the prevalence of both depressive disorders (9%) and unspecified anxiety disorders (13%) in patients with AA was shown to be greater than that in the general population. The prevalence and odds ratio (OR) of depressive disorders (prevalence, 9%; OR, 1.38) and anxiety disorders of which each category had been specifically studied (prevalence, 7%-17%; OR, 1.51-1.69) were markedly lower than that of depressive symptoms (prevalence, 37%; OR, 2.70) and anxiety symptoms (prevalence, 34%; OR, 3.07). Meta-regressions showed that variations in prevalence were mainly associated with methodological differences between studies.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, the separate analyses showed that 7% to 17% of patients with AA had depressive or anxiety disorders that require psychiatric care, including specific medication. Additionally, more than one-third of patients had symptoms that are warning signs and that need monitoring because they can develop into disorders.

Review
A systematic review of clinical trials using single or combination therapy of oral or topical finasteride for women in reproductive age and postmenopausal women with hormonal and nonhormonal androgenetic alopecia.
Female pattern hair loss (FPHL) is a hereditary form of hair loss in women and the most common patterned progressive hair loss in female patients with androgenetic alopecia (AGA). One of the best methods for treating hair loss in women is the finasteride treatment. This systematic review includes a summary of the pharmacology of finasteride and the effect of the drug on women, especially those in the menopausal age group, and is aimed at elucidating methods of preventing systematic side effects. A search of all published literature from 1999 to 2020 has been conducted with the use of PubMed/MEDLINE, Embase, PsycINFO, TRIP Cochrane, as well as Cochrane Skin databases. A total of 380 articles were found, of which 260 articles were removed and 87 review studies were excluded. Lastly, full texts of 33 original articles were reviewed and 14 articles that met the inclusion criteria were selected. Ten out of the 14 articles reported a high rate of alopecia recovery in women taking finasteride. Based on the results, it can be stated that 5 mg of oral finasteride per day could be an effective and safe treatment in normoandrogenic women with FPHL, especially when used in combination with other drugs, such as topical estradiol and minoxidil. We also found that topical finasteride is more effective than other topical formulas for treating hair loss.

Review
: Androgenetic alopecia, the most common cause of non-scarring hair loss, is a consequence of the gradual miniaturization of the hair follicles. In the majority of male androgenetic alopecia cases, a patient's history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. : The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. : The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. : We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.

Review
Recently, the impressive efficacy of JAK-inhibitors (JAK-I) in alopecia areata (AA) has been described in several studies; however, to date, there is limited information on the safety of JAK-I in AA patients. For this reason, on 18 August 2022, a systematic review was performed to collect the premarketing and postmarketing data on the safety of JAK-I in patients treated for AA, evaluating for each molecule the reported adverse events (AEs) in indexed literature and their frequency. The keywords 'alopecia areata' AND 'Jak-inhibitors OR Janus-kinase Inhibitors' were searched on PubMed, Embase and Cochrane databases. Of 407 studies retrieved, 28 papers met the requirements and were used in our review, including five RCTs and 23 case series; overall, 1719 patients were included, and the safety of 6 JAK-I was assessed (baricitinib, brepocitinib, deuruxolitinib, ritlecitinib, ruxolitinib and tofacitinib). Systemic JAK-I were well-tolerated, most of the AEs were mild, and the withdrawal rate for AEs was very low and inferior to placebo in controlled studies (1.6% vs. 2.2%). Laboratory abnormalities represented 40.1% of AEs associated with oral JAK-I, which mostly included the rise in cholesterol, transaminase, triglycerides, creatine phosphokinase (CPK) and sporadic cases of neutro/lymphocytopenia. The remaining AEs involved the respiratory tract (20.8%), the skin (17.2%), the urogenital (3.8%), or the gastroenterological (3.4%) tract. Increased rates of infections involved not only the upper (19.0%) and lower (0.3%) respiratory tract, but also the urogenital system (3.6%) and the skin (4.6%). Isolated cases of grade 3 to 4 AEs have been reported, including myocardial infarction, hypertensive urgencies, cellulitis, rhabdomyolysis, neutropenia and high elevation of creatinine kinase. No fatal outcomes were reported. AEs reported with topical formulation included scalp irritation and folliculitis. The main limit of this review is the lack of data related to postmarketing surveillance, which should be maintained on a long-term basis.

Review
Androgenetic alopecia (AGA) is the most common cause of alopecia in males and females. Minoxidil and finasteride are the only FDA-approved treatments for AGA. New treatments including Platelet Rich Plasma (PRP) and microneedling have shown promising results. The purpose of this literature review was to highlight recent studies examining the effects of topical minoxidil combined with PRP to minoxidil or PRP monotherapy. The method used for this paper includes a systematic review of the literature from 2010 to 2022 using the PubMed, EMBASE, and MEDLINE databases examining studies evaluating combination therapies for AGA. Three randomized control trials compared combination PRP + topical 5% minoxidil to either no treatment, 5% minoxidil, or PRP only. Two studies found increased hair growth at five months and at six months following combined therapy. Another study found an increase in hair density and improved patient satisfaction with combination therapy compared to monotherapy. A prospective study revealed that patients treated with combined 5% minoxidil, PRP, and microneedling reported the highest patient and physician satisfaction compared to minoxidil monotherapy. An observational study evaluating topical 5% minoxidil with PRP reported an increase in hair diameter after one year of combination treatment compared to minoxidil monotherapy. PRP therapy combined with minoxidil and microneedling in a retrospective study was shown to increase hair growth compared to PRP with minoxidil as well as PRP or minoxidil monotherapy. In conclusion, a variety of studies demonstrated superior treatment response with a combination of PRP and minoxidil therapy in patients with AGA. Limitations to this study include different PRP preparation protocols, few randomized control studies, and small sample sizes.

BACKGROUND AND OBJECTIVES
Janus kinase (JAK) inhibitors are emerging as a therapeutic option for alopecia areata. The risk of potential adverse events is currently debated. In particular, several safety data for JAK inhibitors are extrapolated from a single study in elderly patients with rheumatoid arthritis treated with tofacitinib or adalimumab/etanercept as a comparator. The population of patients with alopecia areata is clinically and immunologically different from persons with rheumatoid arthritis and tumor necrosis factor (TNF) inhibitors are not effective in these patients. The objective of this systematic review was to analyze available data on the safety of various JAK inhibitors in patients with alopecia areata.
METHODS
The systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature review was performed by searching PubMed, Scopus and EBSCO databases with the last search on March 13, 2023.
RESULTS
In total, 36 studies were included. The frequency and odds ratio (OR) for most common adverse events versus placebo were: for baricitinib hypercholesterolemia (18.2% vs 10.5%, OR = 1.9) and headache (6.1% vs 5.1%, OR = 1.2), for brepocitinib elevated creatinine level (27.7% vs 4.3%, OR = 8.6) and acne (10.6% vs 4.3%, OR = 2.7), for ritlecitinib acne (10.4% vs 4.3%, OR = 2.6) and headache (12.5% vs 10.6%, OR = 1.2) and for deuruxolitinib headache (21.4% vs 9.1%, OR = 2.7) and acne (13.6% vs 4.5%, OR = 3.3). The respective numbers for upper respiratory infections were: baricitinib (7.3% vs 7.0%, OR = 1.0) and brepocitinib (23.4% vs 10.6%, OR = 2.6); for nasopharyngitis: ritlecitinib (12.5% vs 12.8%, OR = 1.0) and deuruxolitinib (14.6% vs 2.3%, OR = 7.3).
CONCLUSIONS
The most common side effects of JAK inhibitors in patients with alopecia areata were headache and acne. The OR for upper respiratory tract infections varied from over 7-fold increased to comparable to placebo. The risk of serious adverse events was not increased.

Review
BACKGROUND
COVID-19 may play a role in various immune-related dermatologic conditions. The relationship between COVID-19 and alopecia areata remains unclear.
OBJECTIVE
To review the existing literature for clinical studies and reports investigating the association between new-onset alopecia areata or the exacerbation of preexisting alopecia areata following infection with SARS-CoV-2.
METHODS
A systematic review of the literature was performed using PubMed, Embase, and MEDLINE databases from inception to October 2021. Included articles assessed alopecia areata following infection with SARS-CoV-2.
RESULTS
Of 402 total articles, 9 were identified as meeting the inclusion criteria. Six articles described case reports of 7 patients with new-onset alopecia areata following confirmed infection with SARS-CoV-2, and 3 articles reported on alopecia areata recurrence or exacerbation following SARS-CoV-2 infection in patients with preexisting disease. Studies investigating the exacerbation or recurrence of alopecia areata following infection reported mixed findings.
LIMITATIONS
A majority of the included studies were case reports. The heterogeneity of articles precluded data synthesis.
CONCLUSION
Alopecia areata may be a dermatologic manifestation of COVID-19, with cases most often appearing 1 to 2 months following infection. Additional research is necessary to better elucidate the relationship and draw conclusions.
