Alopecia areata (AA) is a long-term autoimmune condition characterized by patchy, non-scarring hair loss. It involves an autoimmune inflammatory process that gives immunity privilege to some hair follicles, while subsequent inflammatory attacks target previously normal hair follicles. One of the most important discoveries in the pathogenesis of this disease is the Janus kinase (JAK)-signal transducer and activator of the transcription (STAT) pathway. Now that a greater understanding of the immunological processes contributing to the pathogenesis has been gained, current trials’ focus was on managing the immunological reaction involved in this disease. Baricitinib is a new first-generation JAK inhibitor that has been studied in multiple trials. This study's objectives were to review existing research and summarize information on the use of Baricitinib to treat AA. The Medline database was searched for relevant published research papers using variations of the following keywords: “AA,” “Baricitinib,” and “JAK inhibitors.” The search covered studies published from 2010–2022. Our findings showed that baricitinib’s use for severe AA in multiple studies generally led to improvement of patients’ conditions with minimal side effects.
Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by recurrent eczematous lesions and intense itch. The disorder affects people of all ages and ethnicities, has a substantial psychosocial impact on patients and relatives, and is the leading cause of the global burden from skin disease. Atopic dermatitis is associated with an increased risk of multiple comorbidities, including food allergy, asthma, allergic rhinitis, and mental health disorders. The pathophysiology is complex and involves a strong genetic predisposition, epidermal dysfunction, and T-cell driven inflammation. Although type-2 mechanisms are dominant, there is increasing evidence that the disorder involves multiple immune pathways. Until recently, the management of AD rested mainly on the judicious use of emollients, topical steroids, and topical calcineurin inhibitors in the majority of patients and systemic immunosuppressants were advocated in severely diseased. However, in the last few years, new therapeutic strategies were designed and developed to target the various steps in the chain of molecular events that lead to the AD phenotype. This review highlights the recent advancements in the management of AD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
