Therapeutic success of tofacitinib in granuloma annulare: A retrospective case series of 15 patients

Abstract

Background Granuloma annulare (GA) is a necrobiotic granulomatous disorder that may sometimes be resistant to treatment, especially the generalised form. Tofacitinib has recently shown promise in the treatment of non-infective granulomatous dermatosis. Objectives In this study, we aimed to evaluate the response of generalised GA to oral tofacitinib. Methods This was a retrospective case series in patients of generalised GA who were treated with oral tofacitinib 5 mg twice a day in a tertiary care centre in north India. Baseline clinical details and histopathological findings were reviewed. Treatment response was noted in the form of clearance of lesions (complete or partial) along with the time taken to achieve the maximum response. Results A total of 15 patients of generalised GA were included in this study, amongst whom nine patients were resistant to conventional therapies whilst the remaining were treatment naïve. Complete clearance of lesions was noted in 11 patients at a mean treatment duration of 4.4 ± 2.1 months whereas clearance was partial in four, with a mean follow-up duration post- treatment in patients who had partial clearance, which is 7.3 ± 2.8 month, with a reduction in erythema and infiltration in those lesions. Adverse effects in the form of hyperlipidemia were observed in two patients. Conclusion Tofacitinib, a JAK-STAT inhibitor is beneficial in treating GA, especially in those with generalised and recalcitrant disease.
