Thirteen-year eczema patient regains scalp hair growth after long-standing alopecia by taking dupilumab. This drug is most commonly used for treating moderate to severe eczema. The findings of this study are published in the journal of JAMA Dermatology.

"We were quite surprised since this patient hadn't grown scalp hair since the age of 2, and other treatments that can help with hair loss did not work in her case," says Maryanne Makredes Senna, MD, of the MGH Department of Dermatology, senior author of the JAMA Dermatology report. "As far as we know, this is the first report of hair regrowth with dupilumab in a patient with any degree of alopecia areata."

In addition to longstanding alopecia, this patient had experienced extensive, treatment-resistant eczema since the age of 7 months. Treatment with prednisone and methotrexate, medications that can suppress the overactive immune system, led to limited improvement in the patient's eczema but no hair regrowth and was therefore discontinued. In July 2017 she began to be treated with weekly injections of dupilumab, which had recently received FDA approval. After six weeks of treatment, which led to significant improvement in eczema symptoms, she also noticed that fine light hairs called vellus hairs were appearing on her scalp.

After seven months of dupilumab treatment, the patient had grown a significant amount of the pigmented hair that typically grows on the scalp. Because of a change in her insurance coverage, she had to discontinue dupilumab for a two-month period, during which she noticed shedding of the recently regrown hair. But after she could resume treatment in April 2018, the hair growth resumed and had continued.

Senna explains that dupilumab's mechanism of targeting a key immune system pathway known to be overactive in eczema could explain its action against alopecia since recent studies have suggested other elements of the same pathway may induce autoimmune hair loss. "Right now, it's hard to know whether dupilumab could induce hair growth in other alopecia patients, but I suspect it may be helpful in patients with extensive active eczema and active alopecia areata," she says. "We've submitted a proposal for a clinical trial using dupilumab in this patient population and hope to be able to investigate it further in the near future." Senna is the principal investigator of the Hair Academic Innovative Research (HAIR) clinical research unit at MGH and an instructor in Dermatology at Harvard Medical School.
