Abstract
Vitiligo is a disease featuring distinct white patches that result from melanocyte destruction. The overall pathogenesis of vitiligo remains to be elucidated. Nevertheless, considerable research indicates that adaptive immune activation plays a key role in this process. Specifically, the interferon-gamma (IFN-γ), C-X-C motif chemokine ligands (CXCL9/10), and C-X-C motif chemokine receptor (CXCR3) signaling axis, collectively referred to as IFN-γ-CXCL9/10-CXCR3 or ICC axis, has emerged as a key mediator responsible for the recruitment of autoimmune CXCR3+ CD8+ T cells. These cells serve as executioners of melanocytes by promoting their detachment and apoptosis. Moreover, IFN-γ is generated by activated T cells to create a positive feedback loop, exacerbating the autoimmune response. This review not only delves into the mechanistic insights of the ICC axis but also explores the significant immunological effects of associated cytokines and their receptors. Additionally, the review provides a thorough comparison of existing and emerging treatment options that target the ICC axis for managing vitiligo. This review aims to foster further advancements in basic research within related fields and facilitate a deeper understanding of alternative treatment strategies targeting different elements of the axis.

Asilian A, Mohammadian P, Shahmoradi Z. Effectiveness of oral tofacitinib treatment on patients with moderate-to-severe alopecia areata in Iran. J Cosmet Dermatol 2024; 23:886-890. [PMID: 37933534 DOI: 10.1111/jocd.16049] [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: 06/29/2023] [Revised: 09/23/2023] [Accepted: 10/12/2023] [Indexed: 11/08/2023]
Abstract
INTRODUCTION Alopecia areata is an inflammatory hair loss and a common autoimmune disease. Conducting treatment studies on alopecia areata is difficult due to unpredictable periods and even spontaneous recovery from the disease. In this study, the effectiveness of tofacitinib in treating alopecia areata was investigated. MATERIALS AND METHODS The severity of the disease was evaluated using the Alopecia Severity Tool (SALT), and based on the medical history and patient's documents and photos, the score before and after the treatment was obtained. The patients were prescribed tofacitinib tablets at a dose of 5 mg twice a day for at least 6 months and were followed for a minimum of 18 months. RESULTS No side effect was observed in 97.9% of the patients. After 6 months, except for three patients who did not need any maintenance dose, others needed an average daily intake of 7 mg of tofacitinib. After 18 months, the hair loss decreased by 6.45 times compared to the beginning and by 0.5 times compared to the end of 6 months (p < 0.05). In addition, it was found that body hair loss decreased 4 times compared to the beginning and 0.6 times compared to the end of 6 months (p < 0.05). The reduction of nail involvement after 18 months and 6 months was 1.2 times and 0.6, respectively, (p < 0.05). CONCLUSION Treatment of alopecia areata with tofacitinib is recommended due to its effectiveness in reducing hair loss on the head, body, and nail involvement with few reversible side effects.

Abstract
Alopecia areata (AA) affects individuals of all ages and is intractable in severe relapsing cases. Dermatologists and other healthcare providers should consider AA in the medical context and prioritize treatment. Several randomized controlled clinical studies on Janus kinase (JAK) inhibitors with different specificities for the treatment of AA are ongoing. These studies have encouraged us to appreciate the importance of a definitive diagnosis and accurate evaluation of AA before and during treatment. Following our previous review article in 2017, here we provide the second part of this two-review series on the recent progress in the multidisciplinary approaches to AA from more than 1800 articles published between July 2016 and December 2022. This review focuses on the evaluation, diagnosis, and treatment of AA. We also provide the latest information on the safety and efficacy of JAK inhibitors for the treatment of AA and describe their mechanisms of action.

Indian Dermatol Online J 2024; 15:49-54. [PMID: 38282998 PMCID: PMC10810385 DOI: 10.4103/idoj.idoj_131_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 06/20/2023] [Accepted: 06/24/2023] [Indexed: 01/30/2024] Open
Abstract
Background Alopecia areata (AA) presents with noncicatricial alopecia and has multifactorial etiology. Janus Kinase inhibitors (JAKibs) with potential efficacy and favorable side-effect profile are the first class of drugs to receive FDA approval in AA. Objectives Our primary objective was to assess the complete response rates to tofacitinib monotherapy in severe and recalcitrant AA, alopecia totalis (AT), and alopecia universalis (AU) patients using the latest percentage change in Severity of alopecia tool (SALT) score. We also aimed to analyze the various systemic agents used by these patients prior to the use of tofacitinib. Materials and Methods Institutional records of 17 patients with severe or refractory AA, AT, and AU treated with tofacitinib monotherapy were analyzed, retrospectively. The response to tofacitinib therapy was determined after calculating percentage change in SALT score. End of treatment was defined as the dose which resulted in a significant response (complete/near complete response was ≥75% hair regrowth from baseline as determined by SALT score). Results Majority of patients had severe AA (SALT ≥ 50) (n = 9/17, 52.94%), while five patients had AT and three had AU. All patients had received either systemic glucocorticoids (GCS), which included oral mini pulse (OMP) (n = 8), intravenous pulse steroids (n = 4), and daily oral GCS (n = 6) or immunosuppressive agents (ISAs) which included cyclosporine (n = 14) followed by methotrexate (n = 6) and azathioprine (n = 6). Mean SALT score prior to starting tofacitinib was 74.23. Mean dose of tofacitinib used was 13.23 mg (10-15 mg) and mean duration of treatment was 9.23 months. Latest percentage change of SALT score ranged from 70.58% to 100%, with an average of 91.47%. Most patients showed complete/near complete response (13/17, 76.47%). Conclusion Tofacitinib was found to be safe and effective in severe/refractory AA, AU, and AT patients recalcitrant to other treatment modalities in our study. Further studies are needed to assess the effect of these targeted drugs on JAK-STAT expression or tissue cytokines involved in the pathogenesis of AA using immunohistochemistry.

Abstract
Treatments for alopecia areata (AA) have traditionally been prescribed off-label, and there has been no universal agreement on how to best manage the condition. Baricitinib is the first oral selective Janus kinase (JAK) inhibitor approved for the treatment of adults with severe AA. As a better understanding of the evidence supporting the management of AA in clinical practice is needed, we conducted a systematic literature review and subsequent narrative review to describe available evidence pertaining to the efficacy and tolerability of treatments currently recommended for adults with moderate-to-severe forms of AA. From 2557 identified records, a total of 53 records were retained for data extraction: 9 reported data from 7 randomized controlled trials (RCTs) versus placebo, and 44 reported data from unique RCTs with no placebo arm, non-randomized trials, or observational studies. Across drug classes, data were reported heterogeneously, with little consistency of data collection or clinical endpoints used. The most robust evidence was for the JAK inhibitor class, in particular the JAK1/JAK2 inhibitor baricitinib. Five RCTs (three for baricitinib) demonstrated a consistent benefit of JAK inhibitor therapy over placebo across various clinical outcomes in adult patients with at least 50% scalp hair loss. Overall, hair regrowth varied widely for the other drug classes and was generally low for patients with moderate-to-severe AA. Relapses were commonly observed during treatment and upon discontinuation. Adverse effects were generally consistent with the known safety profile of each intervention. The heterogeneity observed prevented the conduct of a network meta-analysis or an indirect comparison of different treatments. We found that the current management of patients with moderate-to-severe AA often relies on the use of treatments that have not been well evaluated in clinical trials. The most robust evidence identified supported the use of baricitinib, and other oral JAK inhibitors, in patients with severe AA.

Abstract
The Janus kinase (JAK) and Signal Transducer and Activator of Transcription (STAT) pathway has been identified as a key player in the pathophysiology of alopecia areata and a potential target for therapy. Here, we give a narrative review of what is known about Janus kinase inhibitors in alopecia areata. Several clinical trials as well as smaller studies have demonstrated hair regrowth and remission with oral Janus kinase inhibitors therapy, even in patients who failed conventional treatment. Baricitinib is the only US FDA-approved treatment for alopecia areata but data for other oral Janus kinase inhibitors such as tofacitinib, ruxolitinib and ritlecitinib are also promising. Fewer clinical trials have investigated topical Janus kinase inhibitors for alopecia areata, with many of them terminated early due to unfavourable results. Overall, Janus kinase inhibitors are an efficacious addition to the therapeutic arsenal for treatment-refractory alopecia areata. Further work is needed to examine the effects of long-term usage of Janus kinase inhibitors, the efficacy of topical Janus kinase inhibitors, as well as to identify biomarkers that could predict differential therapeutic responses to the various Janus kinase inhibitors.

Abstract
Background Palmoplantar pustulosis (PPP) is a common chronic and recurrent skin disease of the palms and soles with significant pain, mental distress, and functional disability. PPP is challenging to treat and usually requires prolonged management. Therapy resistance and frequent relapse discourages patients from follow-up. No unified standard and no published therapeutic guidelines have yet been defined on PPP treatment. In general, all therapeutic options known for autoimmune diseases, psoriasis in particular, have been tested in PPP. Tofacitinib, an oral JAK inhibitor, has been approved for the treatment of rheumatoid arthritis and shows promise in the treatment of moderate-to-severe plaque psoriasis. However, no clinical trials or case reports have been conducted to confirm the efficacy of tofacitinib in palmoplantar pustulosis. Methods Six in total with 6 PPP patient, aged 42-58 years were recruited according to the inclusion and exclusion criteria. Patient characteristics, including triggering factors, concomitant diseases, and previous therapeutic drugs, were investigated. All patients experienced a lack of response to topical drugs and at least one systemic agent. During treatment, visits were scheduled at the start of treatment and at 2, 4, and 12 weeks, and efficacy was assessed using the PPP ASI and PPP PGA. Results Our six patients showed an excellent response to tofacitinib as all patients did achieve at least 50% reduction and half of our patients with more than 80% reduction in PPPASI after 4 weeks treatment; at week 12, 5 (83.3%) patients had 80% reduction in PPPASI with no serious adverse events were reported. Conclusion The JAK inhibitor tofacitinib is a promising treatment for refractory palmoplantar pustulosis that requires further clinical observation and research.

Abstract
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 SALT50 (odd ratio [OR], 5.08; 95% confidence interval [CI], 3.49-7.38), SALT90 (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 SALT5 was 0.71(95% CI, 0.65-0.78), SALT50 was 0.54(95% CI 0.46-0.63), SALT90 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.

Abstract
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.

Abstract
Background: Hidradenitis suppurativa (HS), also known as acne inversa or Verneuil's disease, is a chronic, inflammatory, recurrent, and debilitating skin disease of the hair follicles characterized by inflammatory, painful, deep-rooted lesions in the areas of the body characterized by the presence of the apocrine glands. Unfortunately, huge unmet needs still remain for its treatment. Objective: The purpose of our review was collecting all cases, case series, trials, and ongoing studies available in the literature on the use of this class of drugs for HS. Materials and Methods: The investigated manuscripts included trials, reviews, letters to the editor, real-life studies, case series, and reports. Manuscripts were identified, screened, and extracted for the relevant data following the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Results: We selected 56 articles of which 25 met the selection criteria for our review. Among the JAK inhibitors to date, there is only one published clinical trial in the literature (Janus kinase 1 inhibitor INCB054707), a real-life study with 15 patients up to week 24 in which upadacitinib was used and a case series where tofacitinib was successfully used. Conversely, there are several ongoing clinical trials. Conclusions: Results to date in the literature show promising levels of efficacy and the safety of JAK inhibitors in HS. Several clinical trials are underway from which it will be very important to compare the available data. There are still too few studies conducted with a low sample size, so it remains critical to investigate this issue further in the future with a real-life study involving a large sample of patients in order to provide safe and viable therapeutic alternatives for HS.

Abstract
INTRODUCTION Numerous cutaneous dermatoses mediated by cytokines depend on the JAK STAT pathway for intracellular signaling. JAK inhibitors form a useful therapeutic approach in treating these conditions. The literature on effectiveness of JAK inhibitors in treatment of alopecia areata, vitiligo, atopic dermatitis, psoriasis and several other inflammatory and autoimmune diseases is growing, although very few conditions have sufficiently well performed studies to their credit and barring a few indications, their use in rest remains empirical as yet. AREAS COVERED A search of the PubMed database was made using the keywords Janus kinase inhibitors OR JAK inhibitors AND dermatology with the time duration limited to the last 5 years. Here, we review the JAK STAT pathway and the various conditions in which JAK inhibitors are currently used in dermatology and other conditions their use is being explored in. EXPERT OPINION The pathology of a large number of dermatological disorders is mediated via inflammatory cytokines which signal via the JAK STAT pathway. JAKinibs have shown great promise in treating cutaneous disorders refractory to conventional therapy. Their current clinical use in dermatology is based on robust evidence (for some), and anecdotal evidence for most other dermatoses.

A phase 2a randomized vehicle-controlled multi-center study of the safety and efficacy of delgocitinib in subjects with moderate-to-severe alopecia areata. Arch Dermatol Res 2023; 315:181-189. [PMID: 35230488 DOI: 10.1007/s00403-022-02336-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 01/18/2022] [Accepted: 02/10/2022] [Indexed: 12/13/2022]
Abstract
Alopecia areata/AA is an autoimmune cause of nonscarring hair loss. The pathogenesis of AA involves many immune axes, including Th1/Th2 pathways. Delgocitinib is a pan-Janus kinase/JAK inhibitor that broadly blocks pro-inflammatory cytokines and has been effective in other inflammatory skin conditions. Recent human studies/reports have shown that use of some systemic JAK inhibitors led to hair regrowth, suggesting this medication class as a potential therapy for AA. However, topical treatment is desirable due to potential systemic side effects. To assess the efficacy and safety of topical delgocitinib in AA, we conducted a double-blind, randomized, vehicle-controlled clinical trial in 31 moderate-to-severe AA patients that were randomized 2:1 to receive delgocitinib ointment 30 mg/g (n = 20) or ointment vehicle (n = 11) for 12 weeks. The primary endpoint was change in severity of Alopecia Tool/SALT score from baseline to week 12. The secondary endpoint included safety profile by reported adverse events. Twenty-three subjects completed the trial, with eight discontinuing mostly due to voluntary withdrawal. Ten patients receiving delgocitinib ointment and three patients receiving vehicle showed SALT score improvements after 12 weeks, but the mean percent SALT improvement at week 12 compared to baseline between the two arms was not significant (p = 0.92). Our study suggests that delgocitinib ointment is not effective in moderate-to-severe AA, likely due to its inability to penetrate sufficiently deeply into the dermis of the scalp, but larger studies are necessary to assess whether a different formulation of topical JAK inhibitors may be suitable to treat mild or more localized forms of AA.

Abstract
Acute lung injury is a major cause of death in sepsis. Tofacitinib (TOFA), a JAK inhibitor, has anti-inflammatory activity in autoimmune diseases, but its role in acute lung injury in sepsis remains unclear. The purpose of this study is to establish a septic rat model by cecal ligation and perforation, and to evaluate the effect of tofacitinib on the survival rate of septic rat model and its role in acute lung injury in septic rats and the possible mechanism of action. In this study, TOFA (1 mg/kg, 3 mg/kg, 10 mg/kg) was used to observe the survival rate of septic rats. It was found that TOFA (10 mg/kg) significantly improved the survival rate of septic rats. We selected TOFA (10 mg/kg) and focused on the protective effect of TOFA on acute lung injury. The results confirmed that TOFA significantly inhibited the expression of TNF-α, IL-1β, IL-6 and IFN-γ inflammatory factors, reduced the W/D weight ratio of septic lung tissue, and significantly improved lung histopathological damage. These results may be related to the inhibitory effect of TOFA on JAK-STAT/NF-κ B signaling pathway. In conclusion, for the first time, we found that TOFA has a protective effect against sepsis-induced acute lung injury, and it may be a promising drug for the treatment of acute lung injury in sepsis.

Abstract
The aim of this study was to compare the efficacy and safety of treatment with Janus kinase inhibitors for alopecia areata, measured by change in Severity of Alopecia Tool (SALT) score. A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was performed using Medline, EMBASE and Cochrane library. All studies investigating the efficacy of treatments for alopecia areata were included. Primary outcomes were the proportion of patients with alopecia areata achieving 30%, 50%, 75%, 90% and 100% improvement in SALT score after treatment with a Janus kinase inhibitor. A meta-analysis was performed including all randomized controlled trials investigating Janus kinase inhibitors. A total of 37 studies matched the inclusion criteria and were included. Meta-analysis was performed based on 5 randomized studies. Regarding patients with alopecia areata defined as ≥ 50% scalp hair loss, baricitinib 4 mg once daily demonstrated the highest efficacy. However, among patients with alopecia areata defined as a SALT score ≥ 50, oral deuruxolitinib 12 mg twice daily demonstrated the highest efficacy. Deuruxolitinib and baricitinib appear to be promising drugs for the treatment of alopecia areata. However, the response depends on the dosage of the drug. More randomized trials, with identical inclusion criteria and dose and duration of treatment, are required to confirm these findings.

Abstract
Cytotoxic T lymphocyte has been a concern for the etiopathogenesis of alopecia areata (AA), some recent evidence suggests that the regulatory T (Treg) cell deficiency is also a contributing factor. In the lesional scalp of AA, Treg cells residing in the follicles are impaired, leading to dysregulated local immunity and hair follicle (HF) regeneration disorders. New strategies are emerging to modulate Treg cells' number and function for autoimmune diseases. There is much interest to boost Treg cells in AA patients to suppress the abnormal autoimmunity of HF and stimulate hair regeneration. With few satisfactory therapeutic regimens available for AA, Treg cell-based therapies could be the way forward. Specifically, CAR-Treg cells and novel formulations of low-dose IL-2 are the alternatives.

Abstract
Rationale Factors associated with long-term sequelae emerging after the acute phase of COVID-19 (so called "long COVID") are unclear. Here, we aimed to identify risk factors for the development of COVID-19 sequelae in a prospective cohort of subjects hospitalized for SARS-CoV-2 infection and followed up one year after discharge. Methods A total of 324 subjects underwent a comprehensive and multidisciplinary evaluation one year after hospital discharge for COVID-19. A subgroup of 247/324 who consented to donate a blood sample were tested for a panel of circulating cytokines. Results In 122 patients (37.8%) there was evidence of at least one persisting physical symptom. After correcting for comorbidities and COVID-19 severity, the risk of developing long COVID was lower in the 109 subjects admitted to the hospital in the third wave of the pandemic than in the 215 admitted during the first wave, (OR 0.69, 95%CI 0.51-0.93, p=0.01). Univariable analysis revealed female sex, diffusing capacity of the lungs for carbon monoxide (DLCO) value, body mass index, anxiety and depressive symptoms to be positively associated with COVID-19 sequelae at 1 year. Following logistic regression analysis, DLCO was the only independent predictor of residual symptoms (OR 0.98 CI 95% (0.96-0.99), p=0.01). In the subgroup of subjects with normal DLCO (> 80%), for whom residual lung damage was an unlikely explanation for long COVID, the presence of anxiety and depressive symptoms was significantly associated to persistent symptoms, together with increased levels of a set of pro-inflammatory cytokines: interferon-gamma, tumor necrosis factor-alpha, interleukin (IL)-2, IL-12, IL-1β, IL-17. In logistic regression analysis, depressive symptoms (p=0.02, OR 4.57 [1.21-17.21]) and IL-12 levels (p=0.03, OR 1.06 [1.00-1.11]) 1-year after hospital discharge were independently associated with persistence of symptoms. Conclusions Long COVID appears mainly related to respiratory sequelae, prevalently observed during the first pandemic wave. Among patients with little or no residual lung damage, a cytokine pattern consistent with systemic inflammation is in place.

Abstract
Alopecia Areata (AA) is a T-cell mediated autoimmune attack on hair follicles resulting in rapidly developing areas of hair loss involving the scalp and beard that can progress to total scalp hair loss (alopecia totalis) and loss of eyebrows, eyelashes, and total body hair (alopecia universalis). Affected patients have high rates of psychological disorders and decreased quality of life. There are no FDA approved treatments, and the available treatments have a high failure rate. JAK inhibitors are remarkably effective in many autoimmune diseases including Alopecia Areata. Presented is a case report of successful treatment with tofacitinib, and a literature review of the pathophysiology of alopecia areata, the mechanism of action of JAK inhibitors, and the JAK inhibitors in phase 2 and 3 trials.

Abstract
IntroductionAlopecia areata (AA) is an autoimmune hair loss mediated by CD8 + T cells. Treatment for moderate-to-severe AA is still challenging. Janus kinase inhibitors, such as tofacitinib, have been recently investigated as a promising treatment option for AA. Evidence on the combination use of oral tofacitinib and systemic corticosteroids (SCs) for AA is still lacking.ObjectiveTo compare the efficacy and safety of monotherapy of oral tofacitinib and SCs, as well as their combination in patients with moderate-to-severe AA.MethodsPatients with moderate-to-severe AA, who have been treated with at least 3 months of monotherapy of tofacitinib or SCs, or in their combination, were included in this study. The efficacy and adverse events of these treatments were retrospectively analyzed.ResultsSixty-one patients with moderate-to-severe AA were included in this study. There were 12 (66.7%) of 18 patients in the SCs group, 12 (60.0%) of 20 patients in the tofacitinib group, and 18 (78.3%) of 23 patients achieved SALT50, with no significant difference among the three groups. The ratio of patients who achieved SALT50 was significantly higher in patients with a short duration of current hair loss episode (≤2 years) than in those with a duration of current hair loss episode (>2 years) in all the three groups. There were 66.7% patients in the SCs group, 35.0% patients in the tofacitinib group, and 56.5% patients in the combined group that showed adverse effects.ConclusionTofacitinib was an effective treatment for patients with moderate-to-severe AA, and it was more tolerated than SCs. A combination of tofacitinib and SCs may have higher efficacy than SCs alone. Efficacy significantly decreased in patients with a current episode of disease for more than 2 years.

Abstract
Alopecia areata is a common condition that leads to nonscarring hair loss. It can be severe and lead to complete hair loss of the scalp or the whole body. In more severe cases, the disease can be very recalcitrant to treatment and result in a significant impairment of the quality of life of the patients. In recent years, there is increasing evidence on the potential of janus kinase (JAK) inhibitors to treat alopecia areata. In the beginning, this was based on case reports, but later, this potential was further established by large case series and in vitro and in vivo data. It is on this basis that JAK inhibitors are being tested specifically for the treatment of alopecia areata in phase 3, randomized, placebo-controlled trials, raising hopes that there will soon be a JAK inhibitor approved by the US Food and Drug Administration (FDA) for the treatment of alopecia areata. Here we provide a review of the information available on the use of JAK inhibitors to treat alopecia areata, and the potential benefits and risks of this class of medications.

Abstract
Post-Covid pulmonary fibrosis is evident following severe COVID-19. There is an urgent need to identify the cellular and pathophysiological characteristics of chronic lung squeals of Covid-19 for the development of future preventive and/or therapeutic interventions. Tissue-resident memory T (TRM) cells can mediate local immune protection against infections and cancer. Less beneficially, lung TRM cells cause chronic airway inflammation and fibrosis by stimulating pathologic inflammation. The effects of Janus kinase (JAK), an inducer pathway of cytokine storm, inhibition on acute Covid-19 cases have been previously evaluated. Here, we propose that Tofacitinib by targeting the CD8+ TRM cells could be a potential candidate for the treatment of chronic lung diseases induced by acute SARS-CoV-2 infection.

Abstract
Alopecia areata (AA) is an autoimmune disease that affects approximately 2% of the general population. Patients with AA most commonly present with one or more patches of hair loss on the scalp in defined circular areas. A fraction of patients progress to more severe forms of the disease, in some cases with involvement of all body surfaces. The healthy anagen stage hair follicle is considered an immune privileged site, described as an environment that suppresses inflammatory immune responses. However, in AA, this immune privileged state collapses and marks the hair follicle as a target for the immune system, resulting in peri- and intrafollicular infiltration by lymphocytes. The complexity of the inflammatory ecosystem of the immune response to the hair follicle, and the relationships between the cellular and soluble participants, in AA remains incompletely understood. Many studies have demonstrated the presence of various immune cells around diseased hair follicles; however, often little is known about their respective contributions to AA pathogenesis. Furthering our understanding of the mechanisms of disease in AA is essential for the novel identification of targeted therapeutics that are efficacious and have few unintended effects.

Abstract
Alopecia areata (AA) is an immune-mediated hair loss disease for which targeted immune treatments including janus kinase (JAK) inhibitors, e.g., tofacitinib, are emerging. More literature is needed on the safety and efficacy of JAK inhibitors, and treatment has the potential to be cost prohibitive. This study was conducted to measure safety and efficacy outcomes of off-label use of tofacitinib in AA. A secondary outcome was analysis of payment methods. We reviewed 35 AA patients treated with tofacitinib in a specialty hair disease clinic between January 2013 and July 2019 for outcomes, adverse events, and feasibility of treatment. No serious adverse events were experienced. 83.9% of patients experienced clinically significant scalp regrowth, and 32.3% experienced near total/total regrowth. Though this study was confined to retrospective analysis, the results showed that tofacitinib was safe, effective, and practical for this cohort of 35 AA patients.

Abstract
INTRODUCTION Alopecia areata (AA) is an inflammatory and autoimmune form of hair loss, which can present with one patch of hair loss, but in more extreme cases can lead to total body hair loss. There are limited therapeutic options and no cure, but medication can sometimes induce sustained remission. Disease control cannot be guaranteed; even those who regrow all hair on treatment can experience relapse. There are no FDA approved systemic treatments; therefore, an unmet need for safe, and effective treatments exists. Few treatments have been evaluated by randomized controlled trials. Case reports and series indicate oral Janus Kinase (JAK) inhibitors as a potential therapy. Ritlecitinib is a novel oral JAK3-selective inhibitor being investigated as an AA treatment. AREAS COVERED This article introduces ritlecitinib as treatment for AA and considers the mechanism of action, pharmacodynamics, pharmacokinetics, clinical efficacy, and safety [reporting data from a 24-week, phase 2a double-blinded placebo-controlled trial of ritlecitinib in patients with AA who have more than 50% scalp hair loss]. EXPERT OPINION Ritlecitinib offers a novel mode of action, rapid onset, and the capacity for a superior safety profile over other JAK inhibitors. If approved, ritlecitinib will be widely prescribed by physicians overseeing the more severe AA patients for the foreseeable future. As JAK inhibitors regulate the hair growth cycle and have anti-inflammatory effects, the implementation of ritlecitinib in hair loss disorders other than AA, may prove beneficial.

Abstract
Vitiligo is a multifactorial reversible skin disorder characterized by distinct white patches that result from melanocyte destruction. Activated CXCR3+ CD8+ T cells promote melanocyte detachment and apoptosis through interferon-gamma (IFN-γ secretion and chemokines secreted by keratinocytes through the Janus kinase (JAK)/signal transducer and activator of transcription (STAT)-1 signaling pathway results in further recruitment of CXCR3+ CD8+ T cells and the formation of a positive-feedback loop. JAK inhibitors target the JAK/STAT pathway and are now approved to treat many immune-related diseases. In the treatment of vitiligo, JAK inhibitors, including ruxolitinib, baricitinib, and tofacitinib, are effective, supporting the implication of the IFN-γ-chemokine signaling axis in the pathogenesis of vitiligo. However, more studies are required to determine the ideal dosage of JAK inhibitors for the treatment of vitiligo, and to identify other inflammatory pathways that may be implicated in the pathogenesis of this condition.

Abstract
BACKGROUND Alopecia areata (AA) is an autoimmune disorder characterized by nonscarring hair loss that can involve the scalp, face, and body. Severe AA subtypes have a poorer prognosis and can be challenging to treat. Tofacitinib, a recently introduced Janus kinase inhibitor, has shown positive results in treating AA. This multicenter study demonstrates the efficacy of tofacitinib and the patient response rate in a Saudi population. It also highlights patient characteristics that may serve as predictors of the therapeutic response to tofacitinib. METHODS A prospective cohort study design was utilized. Study participants were included from three medical centers in Riyadh, Saudi Arabia. The Severity of Alopecia Tool (SALT) score was used to assess the percentage of hair loss at baseline and the percentage of hair regrowth at 3 and 6 months. RESULTS The sample size was 68 with an average baseline SALT score of 76.8 ± 27.6%. Data at 6 months were available for 45 patients. Of these, 62.2% achieved a SALT score of >50%. Patients with a score of <50% had a significantly higher baseline SALT score compared to patients with >50% score. The past use of systemic steroids was associated with a diminished response to therapy (P = 0.015). The response to therapy was significantly higher in patients with AA compared to alopecia totalis and alopecia universalis. CONCLUSIONS Tofacitinib is an effective and well-tolerated treatment for severe AA and exhibits a good safety profile.

Abstract
BACKGROUND Tofacitinib and ruxolitinib have been used off-label to treat alopecia areata. Although a number of case reports and small studies have been published, there are no comprehensive reviews examining the outcomes of using tofacitinib and ruxolitinib for the treatment of alopecia areata. AIMS The aim of the study was to examine the outcome of patients with alopecia areata treated with oral tofacitinib or ruxolitinib in previously published studies. METHODS A search of MEDLINE, Embase and Cochrane library was conducted. A systematic review and meta-analysis were performed focusing on the Severity of Alopecia Tool 50 achievement rate, the frequency of adverse events and recurrence after discontinuation of treatment. RESULTS A total of 1244 studies were identified of which only 12 studies met the inclusion criteria. Of the 346 patients in these 12 studies, 288 had received oral tofacitinib and 58 had received oral ruxolitinib. The overall Severity of Alopecia Tool50 achievement rate was 66% (95% confidence interval, 54%-76%). Subgroup analysis revealed that drug choice, mean age, sex ratio and alopecia areata subtype ratio did not significantly affect the treatment response. Infections and laboratory abnormalities were the most common adverse events (98 and 65 cases of 319 patients, respectively). Patients treated for more than six months had a greater frequency of laboratory abnormalities as compared to those treated for shorter durations (24% vs. 7%; P = 0.04). Recurrence of alopecia areata was observed within three months after discontinuation of treatment in the majority (74%) of patients. LIMITATIONS This analysis was limited by the small number of observational studies available for review, the heterogeneity of patient characteristics and the lack of long-term data. CONCLUSION Both oral tofacitinib and ruxolitinib are effective and well tolerated in the treatment of alopecia areata. Clinicians should be aware of the expected efficacy, adverse events and high recurrence rate of oral JAK inhibitors for alopecia areata to effectively counsel these patients before starting therapy.

Abstract
Background Alopecia areata (AA) is a hair disease that causes hair loss without scarring. The etiopathogenesis of AA has not been fully understood yet. Objective To determine serum interleukin levels (IL-2, IL-4, IL-15, and IL-17) in patients diagnosed with alopecia areata and to investigate the relationship of IL levels with the duration and severity of alopecia areata and the response to tofacitinib therapy. Methods Patients (≥16 years old) diagnosed with alopecia areata and healthy individuals as a control group was enrolled. Baseline serum interleukin levels of the patients and controls were measured. In the patient group receiving tofacitinib therapy, serum interleukin levels were measured again after 6 months. Disease severity for alopecia areata was assessed using the Severity of Alopecia Tool. Results Sixty-one AA patients and 30 healthy individuals were included; they were comparable regarding age and sex. The mean disease duration for AA was 7 ± 6 years and the baseline mean Severity of Alopecia Tool score was 71 ± 30 (range, 20–100). Baseline IL-2, IL-4 and IL-15 levels were significantly higher in the patient group than those in the control group (p < 0.001 for each). No significant correlation was found between the baseline interleukin levels and either disease duration or disease severity (baseline Severity of Alopecia Tool score). Among the patients receiving tofacitinib (n = 22), all interleukin levels significantly decreased after treatment. However, no significant relationship between the change in interleukin levels and the change in the Severity of Alopecia Tool scores was observed after tofacitinib treatment. Study limitations This is a monocentric study conducted in a single university hospital. Conclusion High interleukin levels in alopecia areata patients and the significant decrease with treatment support the idea that interleukins have a role in pathogenesis. Nevertheless, no relationship could be demonstrated between IL levels and disease duration or severity.

Abstract
Alopecia areata (AA) is a chronic, immune-mediated form of nonscarring alopecia that is multifactorial and results in localized patches. It is often described as a self-limiting condition that results in the spontaneous regrowth of hair in most cases. However, this regrowth may take several months or years to occur in some patients, leading to the development of psychoemotional trauma in those that are affected. Although several therapies for AA have been developed and tested, there is no specific treatment that has been approved, leading to the availability of many off-label conventional treatment options, with very limited responses. More recently, with the advancement of pre-clinical and genetic studies, a greater understanding of the pathomechanisms involved in the development of AA has been uncovered. This has resulted in the introduction of targeted therapies that use small molecules to block specific pathways involved in AA pathophysiology. As such, the use of janus kinase (JAK) inhibitors for treatment of AA has emerged. JAK inhibitors block the T-cell mediated inflammatory response thought to be the driving factor behind AA pathogenesis, by inhibiting the janus kinase (JAK) signal transducer and activator of transcription (STAT) signaling pathway, leading to a reversal of hair loss in AA patients. Thus, in an effort to demonstrate the efficacy of JAK inhibitors in the treatment of AA, several studies have been published within recent years. However, the question remains, “Are JAK inhibitors effective and safe in the management of Alopecia Areata?”. This review aims to provide a comprehensive report on the role, efficacy, and outcomes of using JAK inhibitors in the treatment of AA. To competently answer the research question highlighted, the most recent, quality articles published over a 10–15-year period were sourced using PubMed, NCBI, Research gate, Medline, Cochrane Central Register of Controlled Trials, EMBASE and Google scholar. The literature search was primarily focused on randomized controlled trials (RCTs); however, in the absence of such, only the most recently published case reports, case series, clinical trials and open-label studies published to date were included.

Abstract
Introduction Alopecia areata (AA) is a form of nonscarring alopecia and one of the most common autoimmune disorders. Persistent or severe variants lead to potential disfigurement and are associated with a significant negative impact on the patient's quality of life. Case Presentation A 51-year-old female patient presenting with refractory alopecia universalis was successfully treated with oral tofacitinib. Recurrence was not observed following 17 months of therapy. Discussion/Conclusion None of the currently employed therapies for AA are reliably effective nor are they approved for the disease. In this setting, Janus kinase inhibitors emerge as a promising novel treatment, as increasing evidence supports their effectiveness in AA.

Abstract
BACKGROUND Alopecia areata (AA) is an autoimmune hair loss condition that affects people of all ages. Early age of onset and prolonged disease duration indicate poor prognosis. Janus kinase inhibitors are being investigated in phase 3 clinical trials in adolescents and adults with AA OBJECTIVE: To evaluate the use of oral tofacitinib in pre-adolescent patients with AA. METHODS A retrospective review of case records of all pre-adolescent patients with AA treated with oral tofacitinib in a single center between 2018 and 2019. RESULTS Fourteen patients were identified, aged 7 to 11 years. Nine patients experienced clinically significant improvement in their SALT (Severity of Alopecia Tool) score. Three patients achieved complete remission (SALT score of 0), seven (63.6%) achieved over 50% improvement in SALT score from baseline. One patient had no change from baseline, another experienced additional hair loss. After an average of 9 months of treatment, the median SALT score improvement was 67.7%. The improvement was similar in patients with baseline SALT scores greater than 50 and those with baseline SALT scores below 10. Adverse events were mild. LIMITATIONS The retrospective nature of the data, small sample size, lack of a control group, referral bias to a specialist hair center, and concomitant use of other medications including oral minoxidil in all patients. CONCLUSION There is a role for tofacitinib as a systemic therapy in AA and this should be further evaluated in prospective clinical trials in pre-adolescents.

Abstract
Alopecia areata (AA) is an autoimmune condition that affects up to 2% of the general population. Currently available treatment options for AA are of limited efficacy and can be associated with adverse effects. The advancement in understanding of the genetic and molecular mechanisms of AA has led to the development of novel treatment options, with the Janus kinase (JAK) inhibitor class of drugs at the forefront of ongoing clinical trials. Platelet-rich plasma, fecal transplants, and cytokine-targeted therapy with ustekinumab and dupilumab have also been shown to regrow hair in patients with AA in individual case reports or small studies. Several other novel therapies have preliminary data or are being tested in clinical trials.

Abstract
Alopecia areata (AA) is an autoimmune nonscarring alopecic disorder, which presents with varying amounts of hair loss, ranging from focal patchy loss to entire scalp and body hair loss. Treatment of AA is a challenging issue within dermatology practice. Although many treatment options are present, response to medications remains unsatisfactory, especially in severe and recalcitrant cases. In this study, we present a case of treatment-resistant AU, which was successfully treated by the combination of tofacitinib and oral minoxidil.

Abstract
Alopecia areata is a common autoimmune condition that disproportionately affects children and can significantly hinder quality of life. Few safe and effective therapies are available for the treatment of severely affected pediatric patients. JAK inhibitors have been recently established as an effective and well-tolerated therapy in adults, but there are limited data regarding the use of JAK inhibitors to treat alopecia areata in children. Here, we review the available literature regarding the use of JAK inhibitors in children in dermatology and across other medical disciplines.

Abstract
A 40-year-old woman (case 1) visited the hospital complaining of diarrhea and was diagnosed with ulcerative colitis (UC). She was administered 5-aminosalicylic acid (5-ASA), but developed intolerance. Prednisolone (PSL) was administered, and her symptoms improved. However, alopecia areata developed as the PSL was tapered, and her UC relapsed. Adalimumab, Infliximab (IFX), and golimumab were used, but all showed insufficient efficacy. Therefore, we started tofacitinib (TOF). Her bloody stools and diarrhea improved 3 days after TOF administration, and clinical remission occurred on day 14. Her alopecia areata improved 14 days after starting TOF and improved completely during TOF maintenance therapy. A 19-year-old man (case 2) had developed alopecia areata at 10 years old and was diagnosed with UC at 17 years old. He achieved sustained remission with IFX, but then stopped IFX to receive a live vaccination. His UC relapsed 4 months later, immediately after the live vaccine was administered. Vedolizumab was administered, but was ineffective, as was re-administration of IFX. TOF was administered, and his clinical symptoms improved 7 days later. He achieved clinical remission on day 20. In addition, his hair began to regrow 14 days after starting TOF.

Local heroes or villains: tissue-resident memory T cells in human health and disease. Cell Mol Immunol 2020; 17:113-122.

Abstract
Tissue-resident memory T (TRM) cells are increasingly associated with the outcomes of health and disease. TRM cells can mediate local immune protection against infections and cancer, which has led to interest in TRM cells as targets for vaccination and immunotherapies. However, these cells have also been implicated in mediating detrimental pro-inflammatory responses in autoimmune skin diseases such as psoriasis, alopecia areata, and vitiligo. Here, we summarize the biology of TRM cells established in animal models and in translational human studies. We review the beneficial effects of TRM cells in mediating protective responses against infection and cancer and the adverse role of TRM cells in driving pathology in autoimmunity. A further understanding of the breadth and mechanisms of TRM cell activity is essential for the safe design of strategies that manipulate TRM cells, such that protective responses can be enhanced without unwanted tissue damage, and pathogenic TRM cells can be eliminated without losing local immunity.

Abstract
BACKGROUND Alopecia Areata (AA) is a systemic autoimmune condition that usually starts in childhood. OBJECTIVE This article aims to review genetics, therapy, prognosis, and recent patents for AA. METHODS We used clinical queries and keywords "alopecia areata" AND "childhood" as a search engine. Patents were searched using the key term "alopecia areata" in Patents.google.com and freepatentsonline. com. RESULTS Due to an immune-mediated damage to the hair follicles, hair is lost from the scalp and other areas of the body temporarily or even permanently. Children with AA are generally healthy. Evidence of genetic association and increased predisposition for AA was found by studying families with affected members. Pathophysiologically, T- lymphocytes attack hair follicles and cause inflammation and destruction of the hair follicles and hair loss. In mild cases, there would be well-demarcated round patchy scalp hair loss. The pathognomonic "exclamation mark hairs" may be seen at the lesion periphery. In more severe cases, the hair loss may affect the whole scalp and even the whole body. The clinical course is also variable, which may range from transient episodes of recurrent patchy hair loss to an indolent gradually deteriorating severe hair loss. The treatment of AA depends on factors including patients' age, the extent of the hair loss, duration of disease, psychological impact, availability and side effect profile of the treatments. For localized patchy alopecia, topical application of corticosteroids and/or intralesional corticosteroids are the treatment of choice. Other topical treatments include minoxidil, anthralin, coal tar and immunotherapy. In severe resistant cases, systemic immunosuppressants may be considered. Although herbal medicine, acupuncture, complementary and alternative medicine may be tried on children in some Asian communities, the evidence to support these practices is lacking. To date, only a few recent patents exist in topical treatments, including Il-31, laser and herbal medications. Clinical efficacy is pending for these treatment modalities. CONCLUSION None of the established therapeutic options are curative. However, newer treatment modalities, including excimer laser, interleukin-31 antibodies and biologics, are evolving so that there may be significant advances in treatment in the near future. AA can be psychosocially devastating. It is important to assess the quality of life, degree of anxiety, social phobia and mood of the patients and their families. Psychological support is imperative for those who are adversely affected psychosocially.
