Pyrethrum Root Extract for the treatment of Vitiligo pathology. Design, Molecular Docking, ADME-Tox, MD Simulation, and in-silico investigation. Comput Biol Med 2024; 179:108816. [PMID: 38955123 DOI: 10.1016/j.compbiomed.2024.108816] [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: 02/13/2024] [Revised: 06/04/2024] [Accepted: 06/24/2024] [Indexed: 07/04/2024]
Abstract
This study delves into the therapeutic efficacy of A. pyrethrum in addressing vitiligo, a chronic inflammatory disorder known for inducing psychological distress and elevating susceptibility to autoimmune diseases. Notably, JAK inhibitors have emerged as promising candidates for treating immune dermatoses, including vitiligo. Our investigation primarily focuses on the anti-vitiligo potential of A. pyrethrum root extract, specifically targeting N-alkyl-amides, utilizing computational methodologies. Density Functional Theory (DFT) is deployed to meticulously scrutinize molecular properties, while comprehensive evaluations of ADME-Tox properties for each molecule contribute to a nuanced understanding of their therapeutic viability, showcasing remarkable drug-like characteristics. Molecular docking analysis probes ligand interactions with pivotal site JAK1, with all compounds demonstrating significant interactions; notably, molecule 6 exhibits the most interactions with crucial inhibition residues. Molecular dynamics simulations over 500ns further validate the importance and sustainability of these interactions observed in molecular docking, favoring energetically both molecules 6 and 1; however, in terms of stability, the complex with molecule 6 outperforms others. DFT analyses elucidate the distribution of electron-rich oxygen atoms and electron-poor regions within heteroatoms-linked hydrogens. Remarkably, N-alkyl-amides extracted from A. pyrethrum roots exhibit similar compositions, yielding comparable DFT and Electrostatic Potential (ESP) results with subtle distinctions. These findings underscore the considerable potential of A. pyrethrum root extracts as a natural remedy for vitiligo.

Abstract
Recent studies on molecular pathways have elucidated novel therapeutic approaches in inflammatory and autoimmune skin disorders. Specifically, the dysregulation of the Janus kinase signal transducer and activator of transcription (JAK-STAT) cascade plays a central role in the pathogenesis of many skin conditions. JAK inhibitors, with their ability to selectively target immune responses, are potential treatment options. Using the National Library of Medicine, we provide a comprehensive review of the use of United States Food and Drug Administration (FDA)-approved and emerging JAK or tyrosine kinase 2 (TYK2) inhibitors in a wide range of dermatologic conditions, including psoriasis, vitiligo, systemic lupus erythematosus, hidradenitis suppurativa, dermatomyositis, lichen planus, lichen planopilaris, sarcoidosis and graft-versus-host disease. In patients with psoriasis, oral deucravacitinib (TYK2 inhibitor) has been approved as a once-daily therapy with demonstrated superiority and efficacy over apremilast and placebo and tolerable safety profiles. In patients with vitiligo, topical ruxolitinib (JAK1 inhibitor) is approved as a twice-daily treatment for repigmentation. The efficacy of several other JAK inhibitors has also been demonstrated in several clinical trials and case studies for systemic lupus erythematosus, hidradenitis suppurativa, dermatomyositis, lichen planus, lichen planopilaris, sarcoidosis and graft-versus-host disease. Further investigations with long-term clinical trials are necessary to confirm their utility in treatment and safety for these diseases.

Agranulocytosis and secondary infection related to JAK inhibitors and IL-6 receptor blockers: a disproportionality analysis using the US Food and drug administration adverse event reporting system. Front Pharmacol 2024; 14:1323240. [PMID: 38264533 PMCID: PMC10803638 DOI: 10.3389/fphar.2023.1323240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 12/22/2023] [Indexed: 01/25/2024] Open
Abstract
Background: Given that the fight against coronavirus disease 2019 (COVID-19) is not over, we aimed to explore the occurrence of agranulocytosis and infectious complications in patients with and without COVID-19 following immunoregulatory therapy based on real-world data. Methods: This was a retrospective disproportionality analysis based on the US Food and Drug Administration Adverse Event Reporting System (FAERS). All cases reported between the first quarter of 2004 and the fourth quarter of 2022 about Janus kinase inhibitors (baricitinib, tofacitinib, ruxolitinib) and interleukin-6 receptor blockers (tocilizumab, sarilumab) were collected. Disproportionality analyses were conducted by reporting odds ratio (ROR) and information component (IC). Results: A total of 211,363 cases were recognized from the FDA Adverse Event Reporting System database. Data analysis showed that tocilizumab (reporting odds ratio: 3.18, 95% CI: 3.18-3.29; information component: 1.37, 95% CI: 1.31-1.42), sarilumab (ROR: 1.64, 95% CI: 1.55-1.73; IC: 0.61, 95% CI: 0.43-0.79), baricitinib (ROR: 3.42, 95% CI: 3.19-3.67; IC: 1.43, 95% CI: 1.21-1.65), tofacitinib (ROR: 2.53, 95% CI: 2.49-2.57; IC: 1.11, 95% CI: 1.05-1.16), and ruxolitinib (ROR: 1.87, 95% CI: 1.83-1.91; IC: 0.77, 95% CI: 0.70-0.84) were all associated with secondary infection. The association in the combination group was higher than that in the monotherapy group (ROR: 4.69, 95% CI: 4.53-4.86; IC: 1.73, 95% CI: 1.62-1.84). As for agranulocytosis, tocilizumab (ROR: 1.61, 95% CI: 1.53-1.69; IC: 0.67, 95% CI: 0.50-0.84) and ruxolitinib (ROR: 2.32, 95% CI: 2.21-2.43; IC: 1.18, 95% CI: 1.02-1.33) showed the significant signals. The association was higher in the combination group than in the monotherapy group (ROR: 2.36, 95% CI: 2.15-2.58; IC: 1.20, 95% CI: 0.90-1.51). Secondary infection after treatment with tofacitinib (ROR: 1.37, 95% CI: 1.02-1.84), tocilizumab (ROR: 1.46, 95% CI: 1.01-2.09), and sarilumab (ROR: 2.46, 95% CI: 1.10-5.50) was reported more frequently in COVID-19 than in non-COVID-19 patients. Conclusion: Both Janus kinase inhibitors and interleukin-6 receptor blockers are significantly associated with secondary infection and agranulocytosis, and the combined treatment further increases the association. The correlation with secondary infection in patients treated with tofacitinib, tocilizumab, and sarilumab is higher in COVID-19 than in non-COVID-19 patients.

Abstract
JAK inhibitors target specific inflammatory cytokines involved in various inflammatory diseases. Four molecules have been approved for dermatological use: upadacitinib, baricitinib, abrocitinib and topical ruxolitinib. Off-label prescriptions for other dermatological conditions have been reported. We conducted a narrative review of the literature to assess the long-term safety profile of currently approved JAK inhibitors in dermatology, and their off-label use in skin disorders. We performed literature searches with PubMed and Google Scholar from January 2000 to January 2023, using the keywords "Janus kinase inhibitors", "JAK inhibitors","off-label", "dermatology", "safety", "adverse events", "ruxolitinib", "upadacitinib","abrocitinib" and "baricitinib". Our search yielded a total of 37 dermatological disorders with studies supporting the use of these JAK inhibitors. Preliminary studies indicate that JAK inhibitors generally have a favorable safety profile and can be considered as an option in many dermatological disorders.

Abstract
Human skin pigmentation and melanin synthesis are incredibly variable, and are impacted by genetics, UV exposure, and some drugs. Patients' physical appearance, psychological health, and social functioning are all impacted by a sizable number of skin conditions that cause pigmentary abnormalities. Hyperpigmentation, where pigment appears to overflow, and hypopigmentation, where pigment is reduced, are the two major classifications of skin pigmentation. Albinism, melasma, vitiligo, Addison's disease, and post-inflammatory hyperpigmentation, which can be brought on by eczema, acne vulgaris, and drug interactions, are the most common skin pigmentation disorders in clinical practice. Anti-inflammatory medications, antioxidants, and medications that inhibit tyrosinase, which prevents the production of melanin, are all possible treatments for pigmentation problems. Skin pigmentation can be treated orally and topically with medications, herbal remedies, and cosmetic products, but a doctor should always be consulted before beginning any new medicine or treatment plan. This review article explores the numerous types of pigmentation problems, their causes, and treatments, as well as the 25 plants, 4 marine species, and 17 topical and oral medications now on the market that have been clinically tested to treat skin diseases.

Abstract
Pityriasis rubra pilaris is a rare inflammatory dermatosis characterized by orange-red confluent plaques, hyperkeratotic follicular papules, palmoplantar keratoderma, and, in some cases, erythroderma. The etiology of pityriasis rubra pilaris is unclear. This condition is often treated with oral retinoids and topical corticosteroids, and more recently, biological agents have become the mainstay of treatment. However, there is a paucity of high-quality evidence on the safety and effectiveness of these agents, and the disease often remains refractory to therapy. Herein, we present a case of pityriasis rubra pilaris with a favorable response to treatment with upadacitinib, a Janus kinase inhibitor, which has not been previously reported in the literature for the management of this condition.

Abstract
Topical agents that are currently available for the treatment of atopic dermatitis may represent a valid approach in the management of mild or mild-moderate cases, whereas they are often supplemented with systemic therapies for handling more complex or unresponsive cases. The most used compounds include topical corticosteroids and calcineurin inhibitors, although their use might be burdened by side effects, poor response, and low patient compliance. Consequently, new innovative drugs with higher efficacy and safety both in the short and long term need to be integrated into clinical practice. A deeper understanding of the complex pathogenesis of the disease has led to identifying new therapeutic targets and to the development of innovative therapeutics. This narrative review aims to collect data on selected promising topical drugs that are in an advanced stage of development.

Efficacy and Safety of Upadacitinib for Management of Moderate-to-Severe Atopic Dermatitis: An Evidence-Based Review. Pharmaceutics 2022; 14:pharmaceutics14112452. [PMID: 36432643 PMCID: PMC9698998 DOI: 10.3390/pharmaceutics14112452] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 11/06/2022] [Accepted: 11/11/2022] [Indexed: 11/16/2022] Open
Abstract
Atopic dermatitis (AD) is a common skin condition characterized by inflammation that presents with erythematous and pruritic skin. Its chronic relapse-remitting nature has a significant impact on the quality of life, and often requires ongoing management. Given the limited treatments available for AD, there remains a large need for effective and safe alternative therapies for long-term use. Janus kinase (JAK) inhibitors are a new class of agents that target the JAK-STAT pathway, which plays an important role in the production of proinflammatory cytokines involved in AD pathogenesis. Phase II and III clinical trials revealed that JAK inhibitors, such as upadacitinib, are effective and well-tolerated agents for the treatment of moderate-to-severe AD. As a result, upadacitinib was approved for use in patients with moderate-to-severe AD by the European Medicines Agency (2021), Health Canada (2021) and the FDA (2022) in the last year. It is important for dermatologists to be aware of the clinical evidence to continue incorporating the use of upadacitinib into the treatment algorithm for AD, which will ultimately lead to improved patient outcomes. Therefore, this review is an up-to-date summary of the clinical data available on the efficacy and safety of upadacitinib treatment for AD.

Jalles C, Lepelley M, Mouret S, Charles J, Leccia MT, Trabelsi S. Skin cancers under Janus kinase inhibitors: A World Health Organization drug safety database analysis. Therapie 2022; 77:649-656. [PMID: 35710462 DOI: 10.1016/j.therap.2022.04.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 03/27/2022] [Accepted: 04/29/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Janus kinase (JAK) inhibitors are targeted therapies with a potential imunomodulatory and anti-inflammatory effect, indicated in various dysimmune pathologies. Skin cancers have been reported to occur in patients treated with JAK inhibitors. However, drug safety in clinical trials did not confirm that risk, but these studies are performed on controlled population and in a limited time of follow up. OBJECTIVES The aim of this study is to evaluate in real life condition if a disproportionality signal exists between JAK inhibitors treatment and skin cancers. METHODS We performed cases/non cases analysis in VigiBase® (the World Health Organization international database of suspected adverse drug reaction) using information component to search for a disproportionality signal of skin cancers from JAK inhibitor. We extracted all reports of skin cancers from the French Pharmacovigilance database occurring since 1978 up to 31st December 2019 for the three existing JAK inhibitors on market: ruxolitinib, tofacitinib and baricitinib. Only melanoma, squamous cell carcinoma and Merkel cell carcinoma were analyzed, according to the pathophysiology of these cancers and their link with immunosuppression. RESULTS A disproportionality signal was found positive for squamous cell carcinoma with ruxolitinib (IC025=3.92) and tofacitinib (IC025=0.82), for melanoma with ruxolitinib (IC025=0.81) and tofacitinib (IC025=0.74), and Merkel cell carcinoma with ruxolitinib (IC025=4) and tofactinib (IC025=1.01) and only for Merkel cell carcinoma with baricitinib (IC025=0.53). Moreover, Merkel cell carcinoma, a very rare skin cancer more prevalent in immunodepressed patients was particularly represented in our sample and was associated with a significant disproportionality signal with all the studied JAK inhibitors. CONCLUSION Our study shows that JAK inhibitors could be associated with an extra risk to develop skin cancers. Could an anti-viral or immunovigilance disruption mechanism brought by JAK inhibitors explain an over-risk with Merkel cell carcinoma, which were notably represented in our sample? Considering pharmacovigilance method limitations, further pharmacoepidemiological studies are required to assess a causal link between JAK inhibitors treatment and skin cancers development.

Study of Novel Furocoumarin Derivatives on Anti-Vitiligo Activity, Molecular Docking and Mechanism of Action. Int J Mol Sci 2022; 23:ijms23147959. [PMID: 35887323 PMCID: PMC9316487 DOI: 10.3390/ijms23147959] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/08/2022] [Accepted: 07/13/2022] [Indexed: 12/14/2022] Open
Abstract
Vitiligo is a common chronic dermatological abnormality that afflicts tens of millions of people. Furocoumarins isolated from Uygur traditional medicinal material Psoralen corylifolia L. have been proven to be highly effective for the treatment of vitiligo. Although many furocoumarin derivatives with anti-vitiligo activity have been synthesized, their targets with respect to the disease are still ambiguous. Fortunately, the JAKs were identified as potential targets for the disease and its inhibitors have been proved to be effective in the treatment of vitiligo in many clinical trials. Thus, sixty-five benzene sulfonate and benzoate derivatives of furocoumarins (7a–7ad, 8a–8ag) with superior anti-vitiligo activity targeting JAKs were designed and synthesized based on preliminary research. The SAR was characterized after the anti-vitiligo-activity evaluation in B16 cells. Twenty-two derivatives showed more potent effects on melanin synthesis in B16 cells than the positive control (8-MOP). Among them, compounds 7y and 8 not only could increase melanin content, but they also improved the catecholase activity of tyrosinase in a concentration-dependent manner. The docking studies indicated that they were able to interact with amino acid residues in JAK1 and JAK2 via hydrogen bonds. Furthermore, candidate 8 showed a moderate inhibition of CXCL−10, which plays an important role in JAK–STAT signaling. The RT-PCR and Western blotting analyses illustrated that compounds 7y and 8 promoted melanogenesis by activating the p38 MAPK and Akt/GSK-3β/β-catenin pathways, as well as increasing the expressions of the MITF and tyrosinase-family genes. Finally, furocoumarin derivative 8 was recognized as a promising candidate for the fight against the disease and worthy of further research in vivo.

Abstract
INTRODUCTION Atopic dermatitis (AD) is the most common inflammatory skin disorder. Despite the high disease burden, the therapeutic options are limited and their efficacy in controlling AD might be partially satisfactory. AREAS COVERED Most of the key mediators in AD pathogenesis act through the JAK/STAT signaling pathway, which represents a valid therapeutic target. The first generation of JAK inhibitors, namely tofacitinib and ruxolitinib, inhibit multiple JAKs, whereas newer JAK inhibitors show more selective inhibitory effects for specific JAKs. The aim of this review was to discuss the role of the JAK/STAT pathway in AD and its inhibition, with a special focus on pharmacodynamic properties. We checked the English-language literature, published in the last 15 years using PubMed, Google Scholar, and Scopus. EXPERT OPINION JAK inhibitors have different selectivity for various JAK molecules, which influences their pharmacodynamics, efficacy and safety profile. Since many key cytokines in AD signal through JAK1, and as the selective JAK1 inhibition may be effective, avoiding the concomitant inhibition of JAK2- and JAK3-dependent pathways could be associated with additional safety issues. Therefore, selective JAK1 inhibitors may represent promising therapeutic agents for AD, as they might prevent off-target effects of JAK inhibitors, especially related to the hematologic profile.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment option for patients with refractory cutaneous T-cell lymphoma (CTCL) through replacement of the bone marrow responsible for lymphoma cells and possibly induction of a graft-versus-lymphoma effect. However, allo-HSCT is not always curative; relapse of CTCL occurs in about half of patients post-transplant. Treatment of relapsed CTCL after allo-HSCT is challenging because post-transplant patients are at high risk of graft-versus-host disease, and this condition may be precipitated or exacerbated by standard CTCL therapies. The benefit of each potential therapy must therefore be weighed against its risk of graft versus host disease (GVHD). In this article, we review the management of relapsed CTCL after allo-HSCT. We begin with an exemplative patient whose relapsed Sezary syndrome was successfully treated without development of GVHD. We also report high-throughput T-cell receptor sequencing data obtained during the patient's disease relapse and remission. We then review general guidelines for management of relapsed CTCL and summarize all reported cases and outcomes of relapsed CTCL after transplant. We conclude by reviewing the current CTCL therapies and their risk of GVHD.

Abstract
Janus kinases (JAKs) are a group of intracytoplasmic tyrosine kinase proteins that bind to the cytoplasmic part of the transmembrane cytokine receptors and regulate signaling. The pathophysiology of various autoimmune and autoinflammatory conditions relies on JAK/STAT signaling and therefore, the inhibition of JAK/STAT pathways can be a promising treatment for such diseases, especially inflammatory skin conditions. The current study aimed to evaluate the efficacy of JAK inhibitors in the treatment of immunobullous diseases, including pemphigus, pemphigoid, dermatitis herpetiformis, and epidermolysis bullosa. The databases used to identify the studies were Web of Science, Scopus, and PubMed/Medline for studies published until 2/3/2022. The current review suggests that JAK inhibitors may be revolutionary for the future treatments of dermatologic conditions, especially autoimmune bullous disease. Results also indicated the effectiveness of JAK inhibitors for the treatment of immunobullous diseases.

Abstract
Janus kinase (JAK) inhibitors have become promising treatments for atopic dermatitis (AD), however no study directly comparing JAK inhibitors with each other has been reported. We conducted this network meta‐analysis to determine the comparative efficacy and safety of three common oral JAK inhibitors including abrocitinib, baricitinib, and upadacitinib for moderate‐to‐severe AD. We first identified eligible studies from published meta‐analyzes, then we searched PubMed to obtain additional studies published between February and July 2021. Clinical efficacy and safety were evaluated as primary and secondary outcome, respectively. After extracting data and assessing methodological quality, we utilized ADDIS 1.4 software to conduct pair‐wise and network meta‐analyzes. Ten eligible studies were included in the final analysis. Pooled results that abrocitinib, baricitinib, and upadacitinib obtained higher investigator global assessment (IGA), eczema area, and severity index (EASI) response, however abrocitinib and upadacitinib caused more treatment‐emergent adverse events (TEAEs) regardless of doses, compared with placebo. Network meta‐analyzes revealed that upadacitinib 30 mg was superior to all regimens and upadacitinib 15 mg was better than remaining regimens except for abrocitinib 200 mg in terms of IGA and EASI response. Moreover, abrocitinib 200 mg was superior to abrocitinib 100 mg, baricitinib 1 mg, 2 mg, and 4 mg for clinical efficacy. However, upadacitinib 30 mg caused more TEAEs. Abrocitinib, baricitinib, and upadacitinib were consistently effective therapies in adult and adolescent patients with AD; however, upadacitinib 30 mg may be the optimal option in short‐term studies. More efforts should be done to reduce the risk of TEAEs caused by upadacitinib 30 mg.

Abstract
Atopic dermatitis (AD) is a common chronic pruritic inflammatory cutaneous disease. AD is characterized by intense pruritus and enormous clinical heterogeneity. Treatment goals are to improve skin lesions and minimize exacerbations and symptom burden. Currently, topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI) are still considered the main topical therapies in disease treatment. However, despite being very effective, TCS and TCI are not recommended for continuous long-term use, due to potential safety issues. Although research in AD has focused primarily on systemic drugs, more than 20 new topical compounds are under development to treat the disease. This review aims to provide a synthesized summary of the current knowledge about AD topical treatment, echoing existing gaps and coming research trends. The available data seems promising, with some drugs already approved (ruxolitinib being the most recent), and several are in an advanced stage of development and will soon be available for treatment of mild to moderate disease, namely tapinarof, difamilast, and roflumilast. However, longer and larger prospective studies are needed to assess the long-term efficacy and safety of these new compounds and evaluate their benefits over current treatments.

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
BACKGROUND As a serious global problem, knee osteoarthritis (KOA) often leads to pain and disability. Manual therapy is widely used as a kind of physical treatment for KOA. AIM To explore further the efficacy of Maitland and Mulligan mobilization methods for adults with KOA. METHODS We searched PubMed, the Cochrane Library, EMbase, Web of Science and Google Scholar from inception to September 20, 2020 to collect studies comparing Maitland and Mulligan mobilization methods in adults with KOA. The quality of the studies was assessed using the Physiotherapy Evidence Database Scale for randomized controlled trials. Data analyses were performed using Review Manager 5.0 software. RESULTS A total of 341 articles were screened from five electronic databases (PubMed, the Cochrane Library, EMbase, Web of Science and Google Scholar) after excluding duplicates. Ultimately, eight trials involving 471 subjects were included in present systematic review and meta-analysis. The mean PEDro scale score was 6.6. Mulligan mobilization was more effective in alleviating pain [standardized mean difference (SMD) = 0.60; 95% confidence interval (CI): 0.17 to 1.03, P = 0.007; I 2 = 60%, P = 0.020) and improving Western Ontario and McMaster Universities function score (SMD = 7.41; 95%CI: 2.36 to 12.47, P = 0.004; I 2 = 92%, P = 0.000). There was no difference in the effect of the two kinds of mobilization on improving the range of motion (SMD = 9.63; 95%CI: -1.23 to 20.48, P = 0.080; I 2 = 97%, P = 0.000). CONCLUSION Mulligan mobilization technique is a promising intervention in alleviating pain and improving function score in KOA patients.

Abstract
The major discovery of the novel therapeutic Janus kinase (JAK) inhibitors has been implicated in several dermatological diseases. Recently, studies have shown the efficacy and encouraging results of oral JAK inhibitors as a treatment for alopecia areata (AA). Due to the novelty of this treatment, potential side effects are not fully explored. In this paper, we present a case of a 28-year-old male with a 10-year history of alopecia totalis (AT) treated successfully with tofacitinib with encouraging effects on hair regrowth; however, a significant worsening of the patient’s facial acne was observed four months after AT treatment initiation. JAK inhibitors have promising results in the management of different dermatological conditions including moderatesevere forms of AA with few reported adverse events. Acne exacerbation is a unique observed adverse effect of this therapy. More thorough larger sized studies are needed to further characterize the association between acne exacerbation and the use of JAK inhibitors.

Abstract
The impact of new and emerging therapies on the microenvironment of primary cutaneous lymphomas (PCLs) has been recently raised in the literature. Concomitantly, novel treatments are already used or registered (dupilumab, upadacitinib) and others seem to be added to the armamentarium against atopic dermatitis. Our aim was to review the literature on interleukins 4, 13, 22, and 31, and JAK/STAT pathways in PCLs to elucidate the safety of using biologics (dupilumab, tralokinumab, fezakinumab, nemolizumab) and small molecule inhibitors (upadacitinib, baricitinib, abrocitinib, ruxolitinib, tofacitinib) in the treatment of atopic dermatitis. We summarized the current state of knowledge on this topic based on the search of the PubMed database and related references published before 21 October 2021. Our analysis suggests that some of the mentioned agents (dupilumab, ruxolitinib) and others may have a direct impact on the progression of cutaneous lymphomas. This issue requires further study and meticulous monitoring of patients receiving these drugs to ensure their safety, especially in light of the FDA warning on tofacitinib. In conclusion, in the case of the rapid progression of atopic dermatitis/eczema, especially in patients older than 40 years old, there is a necessity to perform a biopsy followed by a very careful pathological examination.

Abstract
Janus kinase (JAK) inhibitors are emerging treatments for atopic dermatitis (AD). Due to this novel role as a therapeutic option for patients with AD, we aimed to review current evidence on the pathophysiology and the safety and adverse effects (AEs) of oral JAK inhibitors for the treatment of AD utilizing the key terms atopic dermatitis, JAK inhibitors, and adverse effect or event. Our study indicated that oral JAK inhibitors have a moderate safety profile for use in AD in several reviews and phase II or III clinical trials. Headaches, nausea, and nasopharyngitis are the most commonly reported systemic AEs. Furthermore, acne, herpes simplex, herpes zoster, and eczema herpeticum are the most commonly recorded dermatological AEs. Current evidence indicates JAK inhibitors may also have less association with some of the serious AEs, although there is potential for increased risk of asthma, acute pancreatitis, neutropenia, and thrombocytopenia. Whereas data remain limited for the long-term safety of JAK inhibitor use in patients with AD, many ongoing clinical trials have promising preliminary results.

Abstract
Background Reporting quality of systematic reviews and meta-analyses is of critical importance in dermatology because of their key role in informing health care decisions. Objective To assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement guidelines. Methods This review was carried out in accordance with PRISMA guidelines. Included studies were reviews published across 6 years in the top 4 highest-impact-factor dermatology journals of 2017. Records and full texts were screened independently. Data analysis was conducted with univariate multivariable linear regression. The primary outcome was to assess the compliance of systematic reviews and meta-analyses in leading dermatology journals with the PRISMA statement. Results A total of 166 studies were included and mean PRISMA compliance across all articles was 73%. Compliance significantly improved over time (β = .016; P = <.001). The worst reported checklist item was item 5 (reporting on protocol existence), with a compliance of 15% of articles. Conclusion PRISMA compliance within leading dermatology journals could be improved; however, it is steadily improving.

Abstract
BACKGROUND Atopic dermatitis (AD) is one of the serious global problems. There were wide concerns about whether Janus kinase (JAK) inhibitor was an alternative treatment for AD. METHOD Eight databases were searched from the earliest publication date available to January 2, 2021. We included randomized controlled trials comparing JAK inhibitors with control treatment for AD. Data were pooled using Stata.14 software and performed as mean differences (MD) and risk ratios (RR) with 95% CIs. We did subgroup analysis based on specific outcomes. RESULTS A total of studies, ten randomized controlled trials, with 2583 patients were included in the final synthesis. This meta-analysis showed JAK inhibitor resulted in significant improvement on EASI total score (MD = -0.31; 95%CI, -0.46 to -0.17; p = .000; I2 = 90.0%, p = .000) and pruritus numerical rating scale (NRS) score (MD = -1.15; 95%CI, -1.48 to -0.83; p = .000; I2 = 95.9%, p = .000), without the higher risk of total adverse effects (RR = 1.02; 95%CI, 0.90-1.16; p = .745; I2 =27.9%, p = .206). CONCLUSIONS JAK inhibitor was a promising option for atopic dermatitis. More data and surveillance will be needed to identify efficacy, safety, and the risk of adverse effects.

[PMID: 34023008 DOI: 10.1016/s0140-6736(21)00588-2] [Citation(s) in RCA: 245] [Impact Index Per Article: 81.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 02/12/2021] [Accepted: 03/02/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Upadacitinib is an oral Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, and tyrosine kinase 2. We aimed to assess the efficacy and safety of upadacitinib compared with placebo for the treatment of moderate-to-severe atopic dermatitis. METHODS Measure Up 1 and Measure Up 2 were replicate multicentre, randomised, double-blind, placebo-controlled, phase 3 trials; Measure Up 1 was done at 151 clinical centres in 24 countries across Europe, North and South America, Oceania, and the Asia-Pacific region; and Measure Up 2 was done at 154 clinical centres in 23 countries across Europe, North America, Oceania, and the Asia-Pacific region. Eligible patients were adolescents (aged 12-17 years) and adults (aged 18-75 years) with moderate-to-severe atopic dermatitis (≥10% of body surface area affected by atopic dermatitis, Eczema Area and Severity Index [EASI] score of ≥16, validated Investigator's Global Assessment for Atopic Dermatitis [vIGA-AD] score of ≥3, and Worst Pruritus Numerical Rating Scale score of ≥4). Patients were randomly assigned (1:1:1) using an interactive response technology system to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily for 16 weeks, stratified by baseline disease severity, geographical region, and age. Coprimary endpoints were the proportion of patients who had achieved at least a 75% improvement in EASI score from baseline (EASI-75) and the proportion of patients who had achieved a vIGA-AD response (defined as a vIGA-AD score of 0 [clear] or 1 [almost clear] with ≥2 grades of reduction from baseline) at week 16. Efficacy was analysed in the intention-to-treat population and safety was analysed in all randomly assigned patients who received at least one dose of study drug. These trials are registered with ClinicalTrials.gov, NCT03569293 (Measure Up 1) and NCT03607422 (Measure Up 2), and are both active but not recruiting. FINDINGS Between Aug 13, 2018, and Dec 23, 2019, 847 patients were randomly assigned to upadacitinib 15 mg (n=281), upadacitinib 30 mg (n=285), or placebo (n=281) in the Measure Up 1 study. Between July 27, 2018, and Jan 17, 2020, 836 patients were randomly assigned to upadacitinib 15 mg (n=276), upadacitinib 30 mg (n=282), or placebo (n=278) in the Measure Up 2 study. At week 16, the coprimary endpoints were met in both studies (all p<0·0001). The proportion of patients who had achieved EASI-75 at week 16 was significantly higher in the upadacitinib 15 mg (196 [70%] of 281 patients) and upadacitinib 30 mg (227 [80%] of 285 patients) groups than the placebo group (46 [16%] of 281 patients) in Measure Up 1 (adjusted difference in EASI-75 response rate vs placebo, 53·3% [95% CI 46·4-60·2] for the upadacitinib 15 mg group; 63·4% [57·1-69·8] for the upadacitinib 30 mg group) and Measure Up 2 (166 [60%] of 276 patients in the upadacitinib 15 mg group and 206 [73%] of 282 patients in the upadacitinib 30 mg group vs 37 [13%] of 278 patients in the placebo group; adjusted difference in EASI-75 response rate vs placebo, 46·9% [39·9-53·9] for the upadacitinib 15 mg group; 59·6% [53·1-66·2] for the upadacitinib 30 mg group). The proportion of patients who achieved a vIGA-AD response at week 16 was significantly higher in the upadacitinib 15 mg (135 [48%] patients) and upadacitinib 30 mg (177 [62%] patients) groups than the placebo group (24 [8%] patients) in Measure Up 1 (adjusted difference in vIGA-AD response rate vs placebo, 39·8% [33·2-46·4] for the upadacitinib 15 mg group; 53·6% [47·2-60·0] for the upadacitinib 30 mg group) and Measure Up 2 (107 [39%] patients in the upadacitinib 15 mg group and 147 [52%] patients in the upadacitinib 30 mg group vs 13 [5%] patients in the placebo group; adjusted difference in vIGA-AD response rate vs placebo, 34·0% [27·8-40·2] for the upadacitinib 15 mg group; 47·4% [41·0-53·7] for the upadacitinib 30 mg group). Both upadacitinib doses were well tolerated. The incidence of serious adverse events and adverse events leading to study drug discontinuation were similar among groups. The most frequently reported treatment-emergent adverse events were acne (19 [7%] of 281 patients in the upadacitinib 15 mg group, 49 [17%] of 285 patients in the upadacitinib 30 mg group, and six [2%] of 281 patients in the placebo group in Measure Up 1; 35 [13%] of 276 patients in the upadacitinib 15 mg group, 41 [15%] of 282 patients in the upadacitinib 30 mg group, and six [2%] of 278 patients in the placebo group in Measure Up 2), upper respiratory tract infection (25 [9%] patients, 38 [13%] patients, and 20 [7%] patients; 19 [7%] patients, 17 [16%] patients, and 12 [4%] patients), nasopharyngitis (22 [8%] patients, 33 [12%] patients, and 16 [6%] patients; 16 [6%] patients, 18 [6%] patients, and 13 [5%] patients), headache (14 [5%] patients, 19 [7%] patients, and 12 [4%] patients; 18 [7%] patients, 20 [7%] patients, and 11 [4%] patients), elevation in creatine phosphokinase levels (16 [6%] patients, 16 [6%] patients, and seven [3%] patients; nine [3%] patients, 12 [4%] patients, and five [2%] patients), and atopic dermatitis (nine [3%] patients, four [1%] patients, and 26 [9%] patients; eight [3%] patients, four [1%] patients, and 26 [9%] patients). INTERPRETATION Monotherapy with upadacitinib might be an effective treatment option and had a positive benefit-risk profile in adolescents and adults with moderate-to-severe atopic dermatitis.

Abstract
Psoriasis is a chronic inflammatory disorder of the skin and is characterized by hyper-dividing keratinocytes. This hyper-proliferation of keratinocytes is due to the high level of inflammatory cytokines. In this study, we evaluated the effect of topically applied Baricitinib, JAK1/2 inhibitor on chronic 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced psoriasis model in mice. To our knowledge, this is the first report evaluating the topical route of administration of Baricitinib in the context of psoriasis in vivo. TPA-induced inflammation was induced by the topical application of TPA in both ears. Thirty minutes before the application of TPA, the inner and outer surface of each ear was treated with Baricitinib for 6 days. Topical application of Baricitinib inhibited the expression of inflammation markers up-regulated by TPA. Besides, Baricitinib substantially reduced ear swelling, infiltration of leukocytes, the proliferation of epidermal cells, and angiogenesis of the dermal layer. The results suggest that Baricitinib significantly reduced phosphorylation of STAT3 and STAT1 levels in turn attenuating the downstream expression of inflammatory cytokines. Collectively, these results suggest that Baricitinib can be a potential therapeutic through topical route for psoriasis progresses.

Abstract
The evolving discoveries in atopic dermatitis (AD) broaden our understanding of the pathogenesis of the disease and, above all, enable better management for patients. Dupilumab was the first biologic for AD, and since its approval, many new treatments have emerged in both late- and early-stage clinical trials. These trials have led to a further understanding of the pathogenesis of AD and to the identification of additional potential therapeutic targets. This review will highlight the emerging therapies and provide approaches on how to choose the right treatment for your patients.

Abstract
Refractory dermatomyositis (DM) is defined as cases that do not show improvement after initial treatment with two different immunosuppressives combined with corticosteroids with or without intravenous immunoglobulins. In recent years, few studies have reported a positive response to the use of Janus kinase inhibitors (JAK-inhibitors) for the treatment of refractory DM. A systematic literature review was performed for articles studying the use of JAK-inhibitors for the treatment of refractory DM. We identified 38 females and 15 males treated with JAK-inhibitors without serious side effects. Tofacitinib was the most frequently used JAK-inhibitor followed by ruxolitinib. Significant improvement in CDASI score, muscle strength, body weight, and skin lesions were reported in most of the studies. The duration of follow-up ranged from 1 to 15 months without relapse. Therefore, the use of JAK-inhibitors looks promising in the treatment of refractory DM and further high volume research may be required to validate the current concept. As only case reports and series were identified without direct comparison for review, there is a potential risk of bias. Despite these limitations, we believe that the result of this analysis allows a better understanding of treatment options for refractory DM and will help generate a hypothesis that can be further tested.

Abstract
OBJECTIVE To compare the cumulative incidences of malignancies and benign skin masses and the mean age at death or euthanasia in dogs with allergic dermatitis treated long-term with versus without oclacitinib. ANIMALS 660 client-owned dogs. PROCEDURES Medical records were searched to identify dogs with allergic dermatitis treated for ≥ 6 months with oclacitinib (exposed dogs; n = 339) versus other available treatments before the introduction of oclacitinib (nonexposed dogs; 321) and with ≥ 24 months of follow-up information available. Nonexposed dogs were age and breed matched with 321 of the exposed dogs; data for the remained 18 exposed dogs were included in statistical analyses. Results for cumulative incidences of malignancies and other variables were compared between groups, and the effect of daily maintenance dosage of oclacitinib on cumulative incidences of malignancies and other skin masses was evaluated within the exposed group. RESULTS No meaningful differences were detected in the cumulative incidences of malignancies and overall skin masses or the mean age at death or euthanasia for dogs in the exposed group (16.5% [56/339], 56.6% [192/339], and 11.2 years [n = 80], respectively) versus the nonexposed group (12.8% [41/321], 58.3% [187/321], and 11.8 years [71], respectively). There was no association identified between daily maintenance dosage of oclacitinib and odds of malignancy or benign skin masses for dogs in the exposed group. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that long-term treatment with oclacitinib did not pose additional risk for malignancy in dogs; however, veterinarians should continue to observe FDA-approved label warning and precaution statements for oclacitinib and regularly screen for neoplasia in dogs with allergic skin disease treated with or without oclacitinib.

Abstract
Objectives Peficitinib, a novel Janus kinase (JAK) inhibitor, demonstrated promising results in treating RA in phase 3 clinical trials. This in vitro study was undertaken to characterize the pharmacological properties of peficitinib and investigate the involvement of JAK and signal transducer and activator of transcription (STAT) pathways in the pathological processes of SSc, which is also an autoimmune disease. Methods Phosphorylation levels of STAT molecules were assessed in peripheral blood mononuclear cells collected from patients with RA or SSc and healthy subjects, and in skin specimens obtained from 19 patients with SSc. In vitro inhibition of STAT phosphorylation and cytokine/chemokine production by peficitinib, tofacitinib and baricitinib were also characterized. Results Higher spontaneous STAT1 or STAT3 phosphorylation was observed in peripheral T-cells and monocytes from patients with RA and SSc compared with healthy subjects. In skin sections from patients with SSc, phosphorylated STAT3–positive cells were found in almost all cases, irrespective of disease subtype or patient characteristics. Conversely, phosphorylated STAT1-positive cells were observed only in samples from untreated patients with diffuse disease of short duration. Peficitinib inhibited STAT phosphorylation induced by various cytokines, with comparable efficacy to tofacitinib and baricitinib. Peficitinib also suppressed cytokine and chemokine production by peripheral blood mononuclear cells and skin fibroblasts. Conclusion Our results suggest that JAK/STAT pathways are constitutively activated in SSc and RA, and that the JAK inhibitor may represent a novel therapeutic option for SSc.

Enhancing intradermal delivery of tofacitinib citrate: Comparison between powder-loaded hollow microneedle arrays and dissolving microneedle arrays. Int J Pharm 2020; 593:120152.

Abstract
Autoimmune-mediated inflammatory skin diseases, such as psoriasis, alopecia areata, and vitiligo, have been reported as the 4th leading cause of nonfatal disease burden worldwide. This is mainly related to the poor quality of life experienced by these patients. Although topical and systemic steroids represent the most common treatment, the variability in success rates and side effects often lead to treatment discontinuation. Recent off-label clinical studies using oral Janus Kinase (JAK) inhibitors (e.g., ruxolitinib, tofacitinib, baraticinib) have shown promising results. However, frequent side effects, such as infections and blood clots have been reported. Therefore, the aim of this research was to enhance the intradermal delivery of tofacitinib citrate with MN arrays. Using crosslinked hydrogels containing modifying agents (urea, sorbitol and sodium chloride), hollow MN arrays were fabricated and then loaded with tofacitinib citrate. Their efficiency in intradermal delivery of tofacitinib was compared with dissolving MN arrays and a control (Aqueous cream BP), using neonatal porcine skin. Despite the fact that the hydrogel was only present on the outer surface, hollow MN arrays showed comparable resistance to compression values and insertion capabilities to dissolving MN arrays. Although hollow MN arrays containing NaCl in the formulation led to slightly higher depositions of tofacitinib in epidermis and dermis of neonatal porcine skin when compared to a control cream, dissolving MN arrays showed superiority in terms of tofacitinib deposition in the dermis. Indeed, at 24 h of the study, control cream and dissolving MN arrays delivered 143.98 ug/cm2 and 835 ug/cm2 of drug in the dermis, respectively, confirming the enhanced intradermal drug delivery capacity of MN arrays and their potential for treatment of autoimmune skin diseases.

Tofacitinib Loaded Squalenyl Nanoparticles for Targeted Follicular Delivery in Inflammatory Skin Diseases. Pharmaceutics 2020; 12:E1131.

Abstract
Tofacitinib (TFB), a Janus kinase inhibitor, has shown excellent success off-label in treating various dermatological diseases, especially alopecia areata (AA). However, TFB's safe and targeted delivery into hair follicles (HFs) is highly desirable due to its systemic adverse effects. Nanoparticles (NPs) can enhance targeted follicular drug delivery and minimize interfollicular permeation and thereby reduce systemic drug exposure. In this study, we report a facile method to assemble the stable and uniform 240 nm TFB loaded squalenyl derivative (SqD) nanoparticles (TFB SqD NPs) in aqueous solution, which allowed an excellent loading capacity (LC) of 20%. The SqD NPs showed an enhanced TFB delivery into HFs compared to the aqueous formulations of plain drug in an ex vivo pig ear model. Furthermore, the therapeutic efficacy of the TFB SqD NPs was studied in a mouse model of allergic dermatitis by ear swelling reduction and compared to TFB dissolved in a non-aqueous mixture of acetone and DMSO (7:1 v/v). Whereas such formulation would not be acceptable for use in the clinic, the TFB SqD NPs dispersed in water illustrated a better reduction in inflammatory effects than plain TFB's aqueous formulation, implying both encouraging good in vivo efficacy and safety. These findings support the potential of TFB SqD NPs for developing a long-term topical therapy of AA.

Performance of Janus kinase inhibitors in psoriatic arthritis with axial involvement in indirect comparison with ankylosing spondylitis: a retrospective analysis from pooled data. Clin Rheumatol 2020; 40:1725-1737.

Abstract
BACKGROUND AND OBJECTIVE As the well-acknowledged autoimmune disease, Janus kinase (JAK) is thought to play important roles in the progression of tissue injury in spondyloarthropathy. From a current perspective, JAK inhibitors could be applied to both psoriatic arthritis (PsA) and ankylosing spondylitis (AS). Nonetheless, it is reasonable to doubt whether PsA and AS differentially respond to JAK inhibitors. METHODS Different databases were searched for full-text publication based on inclusion and exclusion criteria. For data-pooling, a fixed-effect model was applied if heterogeneity was not detected. All results of the analysis were illustrated as forest plots. Publication bias was assessed using Begg's adjusted rank correlation test. The standard mean difference (SMD) was calculated in continuous variables. The pooled odds ratio was calculated in categorical variables. RESULTS Nine clinical studies were finally included with a 3-month follow-up. The efficacy and safety of JAK inhibitors were comprehensively investigated. JAK inhibitors were proved to be effectively improving disease condition within 3 months (12 weeks) in both PsA and AS. Besides, psoriasis-related dermal lesions could also be improved by JAK inhibitors. Dose-dependent effects suggested that higher dose tofacitinib could bring not only a higher level of treatment response but also more safety concerns. CONCLUSION JAK inhibitors were proved to be effective in improving arthritis symptoms and enhancing the quality of life in both PsA and AS patients. Compared with AS, JAK inhibitors seemed to perform better in PsA treatment. However, the frequency of adverse events PsA and AS in comparison with the placebo group showed no difference. Higher dose of tofacitinib could attain better treatment response without increasing adverse events in short-term follow-up. KEY POINTS • JAK inhibitors were proved to be effective in improving arthritis symptoms and enhancing the quality of life in both PsA and AS patients. • Compared with AS, JAK inhibitors seemed to perform better in PsA treatment. • The frequency of adverse events PsA and AS in comparison with the placebo group showed no difference. • Higher dose of tofacitinib could attain better treatment response without increasing adverse events in short-term follow-up.

Abstract
Chronic pruritus, defined as an unpleasant sensation resulting in a need to scratch that lasts more than 6 weeks, is a prevalent and bothersome symptom associated with both cutaneous and systemic conditions. Due to complex pathogenesis and profuse contributing factors, chronic pruritus therapy remains challenging. Regardless of the well-established antipruritic properties of classic pharmacotherapy (topical therapy, phototherapy and systemic therapy), these methods often provide insufficient relief for affected individuals. Owing to the growing interest in the field of pruritic research, further experimental and clinical data have emerged, continuously supporting the possibility of instigating novel therapeutic measures. This review covers the most relevant current modalities remaining under investigation that possess promising perspectives of approval in the near future, especially opioidergic drugs (mu-opioid antagonists and kappa-opioid agonists), neurokinin-1 receptor antagonists, biologic drugs, Janus kinase inhibitors, ileal bile acid transporter inhibitors, aryl hydrocarbon receptor agonists and histamine H4 receptor antagonists.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a common and debilitating dermatosis that often impacts the physical and psychological quality of life in children and adults. A limited number of treatment options are available for AD, and often these treatments result in an insufficient response or may be contraindicated for some patients. This treatment gap creates an increasing demand for alternative AD therapies. The Janus kinase (JAK)-signal transducers and activators of transcription (STAT) pathway is known to play a critical role in the dysregulation of immune responses in AD. Inhibition of the JAK enzymes in the JAK-STAT pathway has shown potential for the treatment of this chronic skin condition. AREAS COVERED We review the evolving efficacy and safety profile of abrocitinib, an oral JAK1 inhibitor, in the treatment of AD based on the data available from phase I, II, and III clinical trials. EXPERT OPINION Evidence supports clinical efficacy, improved pruritus and an acceptable safety profile, making abrocitinib a viable alternative to conventional AD therapies. Pivotal phase III trials included subjects aged 12 years and above, providing a new mechanism of action for future treatment of adolescent and adult AD. Further investigations are required to have a thorough understanding of abrocitinib in the treatment of AD.

Abstract
Caffeic acid (CA) is produced from a variety of plants and has diverse biological functions, including anti-inflammation activity. It has been recently demonstrated that caffeoyl-prolyl-histidine amide (CA-PH), which is CA conjugated with proline-histidine dipeptide, relieves atopic dermatitis (AD)-like phenotypes in mouse. In this study, we investigated the molecular mechanism underlying CA-PH-mediated alleviation of AD-like phenotypes using cell line and AD mouse models. We confirmed that CA-PH suppresses AD-like phenotypes, such as increased epidermal thickening, infiltration of mast cells, and dysregulated gene expression of cytokines. CA-PH suppressed up-regulation of cytokine expression through inhibition of nuclear translocation of NF-κB. Using a CA-PH affinity pull-down assay, we found that CA-PH binds to Fyn. In silico molecular docking and enzyme kinetic studies revealed that CA-PH binds to the ATP binding site and inhibits Fyn competitively with ATP. CA-PH further suppressed spleen tyrosine kinase (SYK)/inhibitor of nuclear factor kappa B kinase (IKK)/inhibitor of nuclear factor kappa B (IκB) signaling, which is required for nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation. In addition, chronic application of CA-PH, in contrast with that of glucocorticoids, did not induce up-regulation of regulated in development and DNA damage response 1 (REDD1), reduction of mammalian target of rapamycin (mTOR) signaling, or skin atrophy. Thus, our study suggests that CA-PH treatment may help to reduce skin inflammation via down-regulation of NF-κB activation, and Fyn may be a new therapeutic target of inflammatory skin diseases, such as AD.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic inflammatory skin disease mediated by multiple signals including janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. Current therapeutic armamentarium consists of a limited number of drugs which may result in the insufficient management of AD. Preclinical evidence regarding inhibition of JAK/STAT led to the development of a promising class of therapeutics, namely, JAK inhibitors. Baricitinib, a novel JAK1/JAK2 inhibitor is currently under investigation in AD clinical trials. AREAS COVERED This review offers an overview of Baricitinib and examines clinical efficacy and safety data in patients with moderate-to-severe AD. EXPERT OPINION Baricitinib showed promising preliminary data in terms of efficacy in phase II and III trials, with a very rapid onset of response and great improvements of itch and sleep disturbances. These aforementioned aspects combined with the advantage of an oral formulation have reduced drug production costs compared to biologic agents and could lead to consideration of baricitinib as a first line systemic treatment. Also, in some countries, it could be a therapeutic option in the case of contraindication or failure of conventional systemic drugs prior to biologic therapies. Data related to long-term safety and efficacy will be important to refine the place-in-therapy of this drug.

Abstract
In cutaneous leishmaniasis, the immune response is not only protective but also mediates immunopathology. We previously found that cytolytic CD8 T cells promote inflammatory responses that are difficult to treat with conventional therapies that target the parasite. Therefore, we hypothesized that inhibiting CD8 T-cell cytotoxicity would reduce disease severity in patients. IL-15 is a potential target for such a treatment because it is highly expressed in human patients with cutaneous leishmaniasis lesions and promotes granzyme B‒dependent CD8 T-cell cytotoxicity. Here we tested whether tofacitinib, which inhibits IL-15 signaling by blocking Jak3, might decrease CD8-dependent pathology. We found that tofacitinib reduced the expression of granzyme B by CD8 T cells in vitro and in vivo systemic and topical treatment, with tofacitinib protecting mice from developing severe cutaneous leishmaniasis lesions. Importantly, tofacitinib treatment did not alter T helper type 1 responses or parasite control. Collectively, our results suggest that host-directed therapies do not need to be limited to autoimmune disorders and that topical tofacitinib application should be considered a strategy for the treatment of cutaneous leishmaniasis disease in combination with antiparasitic drugs.

Abstract
The development of immunotherapy has led to a paradigm shift in the treatment of both solid and hematologic malignancies. As immunomodulatory therapies are employed with increasing frequency, a greater number of immune-related adverse reactions are being reported, and the majority of these involve the skin. As a result, dermatologists are increasingly becoming involved in the management of these cutaneous adverse reactions-often providing critical recommendations regarding ongoing cancer treatment. Cutaneous immune-related adverse reactions can vary significantly from patient to patient, making early recognition and timely intervention imperative to mitigate associated morbidity and potential treatment interruption. Although there is considerable overlap in the cutaneous adverse events caused by these immune checkpoint inhibitors, specific eruptions are characteristically associated with particular checkpoint inhibitors. In addition, a patient's comorbidities or immune status can play a significant role in the presentation and management of such adverse reactions. This review characterizes and provides management guidelines for the various cutaneous toxicities associated with checkpoint inhibitor therapy, including CTLA-4 inhibitors, PD-1 inhibitors, and PD-L1 inhibitors. © 2020 Elsevier Inc.

Abstract
Immunosuppressive and immunomodulatory therapies are important in dermatology, but indications are influenced by SARS-CoV-2. We will focus on skin disorders such as autoimmune connective tissue disorders, neutrophilic dermatoses, and vasculitis. Immunomodulators such as colchicine and antimalarials can easily be preferred taking their beneficial effects on COVID-19 into consideration and also given their wide spectrum of action. Among the conventional therapies, methotrexate, azathioprine, and mycophenolate mofetil increase the risk of infection, and thus their use is recommended only when necessary and at low doses. On the other hand, use of cyclosporine is also not recommended as it increases the risk of hypertension, which is susceptible to COVID-19. Anti-TNF agents from among the biological therapies appear to be slightly risky in terms of susceptibility to infection. However, there are ongoing studies which suggest that some biological treatments may reduce cytokine storm impeding the COVID-19 progression as a result, in spite of their susceptibilities to COVID-19. Patients, who will be started on immunosuppressive therapy, should be tested for COVID-19 prior to the therapy, and in the event that COVID-19 is suspected, the therapy should be discontinued.

Risk of infections in patients with myeloproliferative neoplasms-a population-based cohort study of 8363 patients. Leukemia 2020; 35:476-484. [PMID: 32546727 DOI: 10.1038/s41375-020-0909-7] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2020] [Revised: 05/25/2020] [Accepted: 06/03/2020] [Indexed: 12/22/2022]
Abstract
Infections are a common complication in patients with many hematologic malignancies, however, whether patients with myeloproliferative neoplasms (MPN) also are at an increased risk of infections is largely unknown. To assess the risk of serious infections, we performed a large population-based matched cohort study in Sweden including 8 363 MPN patients and 32,405 controls using high-quality registers between the years 1992-2013 with follow-up until 2015. The hazard ratio (HR) of any infection was 2.0 (95% confidence interval 1.9-2.0), of bacterial infections 1.9 (1.8-2.0), and of viral infections 2.1 (1.9-2.3). One of the largest risk increases was that of sepsis, HR 2.6 (2.4-2.9). The HR of any infection was highest in primary myelofibrosis 3.7 (3.2-4.1), and significantly elevated in all MPN subtypes; 1.7 (1.6-1.8) in polycythemia vera and 1.7 (1.5-1.8) in essential thrombocythemia. There was no significant difference in risk of infections between untreated patients and patients treated with hydroxyurea or interferon-α during the years 2006-2013. These novel findings of an overall increased risk of infections in MPN patients, irrespective of common cytoreductive treatments, suggest the increased risk of infection is inherent to the MPN.

Abstract
Dermatomyositis is a rare inflammatory disease with characteristic cutaneous findings and varying amounts of systemic involvement. Patients may present with skin disease alone, have concomitant muscle disease, or have extracutaneous manifestations such as pulmonary disease or an associated malignancy. Given such diverse presentations, dermatomyositis is both a diagnostic and therapeutic challenge. However, a prompt diagnosis is of utmost importance to institute adequate therapy and screen patients for an associated malignancy. Dermatologists should play a crucial role in the diagnosis and management of patients with dermatomyositis as cutaneous disease tends to be chronic, negatively impact quality of life, and be more recalcitrant to therapy. In this review, we discuss diagnosis, with a focus on myositis-specific antibodies and their associated phenotypes. We also review therapies available for this often refractory skin disease.
