Objective: We sought to investigate the incidence of sequelae, including less well-known sequelae, and long-term prognosis in patients with DRESS/drug-induced hypersensitivity syndrome. Methods: A retrospective cohort study was conducted at a medical center in northern Taiwan using a DRESS/drug-induced hypersensitivity syndrome database. Patients who were followed up for at least 1 year were included in the study. Results: Nine patients died before interview, whereas 43 patients completed a specially designed questionnaire. The overall cumulative incidence of long-term sequelae was 11.5% (6 of 52 patients). Four patients developed autoimmune diseases, specifically Graves disease (n = 2), type 1 diabetes mellitus (n = 1), and autoimmune hemolytic anemia (n = 1). Alopecia areata was also noted in 1 of the 2 patients with Graves disease. The other 2 patients developed renal failure after visceral involvement and required lifetime hemodialysis. Limitations: Our study included a small number of patients. Further, viral studies were not performed. Conclusion: The sequelae of DRESS can be divided into 2 major types that appear to occur in different age groups: young patients tend to develop autoimmune diseases, whereas elderly patients are more vulnerable to end-organ failure. ? 2011 by the American Academy of Dermatology, Inc.enautoimmune diseasesdrug reaction with eosinophilia and systemic symptomsdrug-induced hypersensitivity syndromesequelae[SDGs]SDG3adult; aged; alopecia areata; article; autoimmune hemolytic anemia; clinical article; DRESS syndrome; female; follow up; Graves disease; hemodialysis; human; incidence; insulin dependent diabetes mellitus; kidney failure; male; medical record review; priority journal; prognosis; Taiwan; Acute Kidney Injury; Adult; Aged; Aged, 80 and over; Autoimmune Diseases; Cohort Studies; Diabetes Mellitus, Type 1; Drug Hypersensitivity; Drug Toxicity; Eosinophilia; Female; Graves Disease; Humans; Male; Middle Aged; Prognosis; Retrospective Studies; Taiwanjournal article10.1016/j.jaad.2012.08.009229592302-s2.0-84873704492
