July 2024 in “Journal of Investigative Dermatology” JAK inhibitors improve hair growth in alopecia areata, especially in patchy types.
June 2024 in “Military medicine” This review explored treatment options for alopecia areata in the military health care system, evaluating the pathogenesis and impact of the condition as well as the efficacy and safety of FDA-approved JAK inhibitors, baricitinib and ritlecitinib.
June 2024 in “Military Medicine” Access to JAK inhibitors for alopecia areata should be improved in the Military Healthcare System.
May 2024 in “Archives of dermatological research” This study found that Enz_MoriL, a compound derived from Morus alba L., promotes hair follicle cell proliferation by affecting the Wnt/β-catenin pathway and can counteract an alopecia areata-like condition by suppressing the JAK-STAT signaling in human hair follicle dermal papilla cells.
In this retrospective study, researchers found that baricitinib was effective for treating moderate to severe alopecia areata, with response rates in 24 patients comparable to existing real-world data, and no new safety concerns were identified.
April 2024 in “Frontiers in pharmacology” This study compared JAK inhibitors for moderate-to-severe alopecia areata and found brepocitinib 30mg and deuruxolitinib 12mg to be most effective, though deuruxolitinib may cause more adverse events. Further research is needed for long-term efficacy and safety.
In this case study, a patient with refractory oral lichen planus experienced marked improvement within one month of daily treatment with baricitinib, contributing to the evidence supporting the use of JAK inhibitors for lichen planus.
January 2024 in “Updates in clinical dermatology” This paper reviews the autoimmune disorder alopecia areata, its progression, and its significant emotional and psychological impact, but reports no new clinical findings.
January 2024 in “Journal of Crohn's and colitis” This study reports that JAK inhibitors were effective in inducing remission in ulcerative colitis patients and presented an acceptable safety profile with a range of manageable side effects.
January 2024 in “Wiadomości Lekarskie” This report highlights that a coherent vision and collaboration are needed in Poland to address healthcare workforce shortages, including allowing domestic academic titles to confirm Polish language proficiency.
January 2024 in “International Journal of Dermatology Venereology and Leprosy Sciences” This literature review indicates that tofacitinib, both orally and topically, holds promise as a safe and effective treatment for various dermatological conditions in pediatric patients, though its use requires careful consideration of its benefits and risks.
This case report presented the successful treatment of a patient with alopecia universalis using tofacitinib.
November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that in mice, hyper-activated JAK-STAT1 signaling due to EGFR inhibitor treatment leads to scarring alopecia, but JAK1/2 inhibition can restore hair follicle immune privilege and promote new hair growth.
November 2023 in “Journal of Investigative Dermatology” JAK inhibitors are effective and generally safe for treating alopecia areata, but monitoring for side effects is important.
November 2023 in “Journal of Investigative Dermatology” In this study, patients with alopecia areata displayed altered scalp microbiota compared to healthy controls, and treatment with JAK kinase inhibitors largely restored these microbial changes, providing insights into the potential role of the skin microbiome in alopecia areata.
November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, treatment with oral JAK inhibitors was associated with improved disease outcomes in 80.6% of patients with refractory lichen planopilaris over a mean duration of 5 months.
October 2023 in “Frontiers in medicine” This study analyzed screening data from 218 alopecia areata patients before starting Janus kinase inhibitors, revealing the importance of pre-treatment screening due to risks of infections like tuberculosis and hepatitis B, with 74.8% of patients proceeding to treatment in real-world settings.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.
September 2023 in “JAAD case reports” In this review, the authors noted that while baricitinib, a treatment for refractory rheumatoid arthritis and severe alopecia areata, shows promising efficacy, it may pose risks of serious infections and malignancy due to immune downregulation.
