Late sequelae of drug reaction with eosinophilia and systemic symptoms (DRESS) cause thyroid dysfunction and thyroiditis: review of literature

Abstract

Abstract Drug reaction with eosinophilia and systemic symptoms (DRESS) is one of the severe cutaneous adverse drug reactions (SCARs) with high mortality rate and variable long term sequelae, especially in thyroid dysfunction and thyroiditis. In this article, we review clinical course, culprit drugs, onset of diagnosis, and type of thyroid dysfunction in DRESS patients. There were a total of 51 cases including 12 children (aged less than 18 years old) and 39 adults from our review. The most common thyroid dysfunction was Hashimoto’s thyroiditis (41/51=80.4%) including anti-thyroid antibody positive (29/51=56.9%), possible/compatible with Hashimoto’s thyroiditis (12/51=23.5%) both in the children (n=12) and adult (n=39), Graves’ disease/hyperthyroidism (7/51=13.7%) and non-specific hypothyroidism (3/51=5.9%), respectively. The most common culprit drugs and onset of thyroid dysfunction after DRESS diagnosis in children aged less than 18 years include antiepileptic drugs (phenytoin, phenobarbital, carbamazepine) (range 0–8 months, median 2 months) and sulfa groups (sulfasalazine, sulfamethoxazole, sulfonamide) (range 1–4 months, median 2 months). Data of prevalence, type, and clinical course of thyroid dysfunction from DRESS is important for clinicians to recognize for monitoring its sequelae and provide plans for treatment.
