Interestingly, my Bichon Frise, Musette (who won me at an Arthritis Foundation Charity auction) developed horrible hair loss from eczema (she has given me permission per HIPAA to give out this information as well as her name). She is now treated with a JAK kinase inhbitor called oclacitinib (Apoquel) and is doing well on it. (Fortunately, it is no where near the price of tofacitinib). I expected to see a study show the same in humans as you now report. This is good news as eczema can be very difficult to treat in some people and carries a significant reduction in quality of life in those who are severely affected. Musette wishes everyone a Happy Thanksgiving!
