Stevens–Johnson Syndrome and Herpes Simplex Type 1 Infection during Adalimumab Therapy for Crohn’s Disease

Abstract EN

Stevens–Johnson syndrome (SJS) is a severe mucocutaneous adverse drug reaction with a relatively high mortality rate.

SJS is described during herpes simplex virus type 1 (HSV1) infection and, rarely, even during adalimumab therapy.

We report the case of a patient with Crohn’s disease who developed SJS during an HSV1 infection and a contemporaneous anti-TNFα therapy with adalimumab.

Remission was achieved with suspension of adalimumab and high doses of intravenous steroids and antivirals.

Patients with HSV1 infection and on adalimumab therapy have a combined risk of SJS and should be monitored closely.
