Unforeseen gastrointestinal events following antituberculous therapy

Abstract

Eosinophilic enteritis is a rare entity affecting human gastrointestinal tract. The exact etiology is unknown, and some drugs are implicated in causing this condition. We report a case of drug-induced eosinophilic enteritis, caused by antituberculous therapy (ATT). The cessation of ATT-induced clinical remission and symptoms were reproduced on drug re-challenge, which corroborated our diagnosis.
