Irish Dermatologists' Experience With JAK Inhibitors In Alopecia Areata

In this study, withdrawal of baricitinib therapy in patients with severe alopecia areata who had achieved hair regrowth led to a loss of benefit in almost all patients, suggesting that continued treatment is necessary to maintain hair regrowth.

This study found that the oral JAK1/JAK2 inhibitor deuruxolitinib effectively promoted hair regrowth and patient satisfaction in adults with alopecia areata over 24 weeks.

In this research, the authors reported that long-term treatment with the JAK1/JAK2 inhibitor baricitinib effectively maintains hair regrowth in patients with severe alopecia areata and may gradually improve outcomes for partial responders over 104 weeks, without increasing side effect incidence.

This consensus statement outlines a treatment algorithm for alopecia areata, detailing systemic treatment indications and options, including EMA-approved medications baricitinib and ritlecitinib for severe cases, as well as other off-label treatments and adjuvant therapies like oral minoxidil.

Ritlecitinib effectively treats alopecia areata and is well-tolerated.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.
