Recurrent subacute cutaneous lupus erythematosus following exposure to different drugs

Recurrence of Drug-Induced Lupus Secondary to Vedolizumab Use in a Patient With Crohn's Disease

Drug-induced lupus is an autoimmune phenomenon characterized by the development of systemic lupus erythematosus-like clinical features after drug exposure. The entity is a clinical diagnosis. Evaluation consists of recognizing systemic lupus erythematosus-like features, identifying an appropriate causative agent, observing elevations of characteristic autoantibodies, and obtaining positive response with drug discontinuation. Vedolizumab is an anti-α4β7 antibody used in the treatment of ulcerative colitis and Crohn's disease. We report a novel case of drug-induced lupus recurrence secondary to vedolizumab use in a patient with Crohn's disease, emphasizing diagnostic evaluation, and provide a brief review of the published literature.

Cutaneous drug-induced lupus erythematosus: Clinical and immunological characteristics and update on new associated drugs

Cutaneous drug-induced lupus erythematosus (CDILE) is a lupus-like syndrome related to drug exposure which typically resolves after drug discontinuation. It can present as a systemic or a sole cutaneous form and different drugs may be associated with each form. CDILE pharmacoepidemiology is constantly changing. Indeed, older drugs primarily associated with systemic CDILE are no longer prescribed and new drugs associated with either cutaneous or systemic CDILE have emerged. The present study discusses the clinical and laboratory aspects of CDILE and the postulated pathogenesis, and it provides an update on implicated drugs. We performed a literature review to single out the new drugs associated with CDILE in the past decade (January 2010-June 2020). Among 109 drugs reported to induce CDILE in 472 patients, we identified anti-TNFα, proton-pump inhibitors, antineoplastic drugs, and, in particular, checkpoint inhibitors, as emerging drugs in CDILE. Most of the published studies are cases reports or small case series, and further larger studies as well as the development of validated classification criteria are needed to better understand and characterize their implication in CDILE.

Therapeutic options for cutaneous lupus erythematosus: recent advances and future prospects

INTRODUCTION

Treatment and prevention are of critical importance in patients with cutaneous lupus erythematosus (CLE), as the disease can have a devastating effect on patient well-being and quality of life.

AREAS COVERED

We conducted a selective search of the PubMed database for articles published between December 2010 and November 2015. This review encompasses both non-pharmaceutical (photoprotection, smoking cessation, drug withdrawal, and vitamin D replacement) and pharmaceutical (topicals, antimalarials, immunosuppressives, biologics, etc.) interventions used in the treatment of CLE. Expert Commentary: Recent work has expanded our understanding of established therapies as well as introduced new treatments for consideration, though existing medications still prove inadequate for a subset of patients. Changes in trial design may help to alleviate this issue.
