Drug reaction with eosinophilia and systemic symptoms: A single center descriptive observational study.

Abstract：

:Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe adverse cutaneous drug reaction with mortality up to 10%. It is a rare condition with risk varying between 1 in 1000 and 1 in 10 000 drug exposures. The aim of the study was to describe clinical features, management and drugs responsible for causing DRESS. The study was retrospective, observational study. The data of patients admitted to hospital with diagnosis of DRESS during study period (March 2018 to February 2020), were retrieved and analyzed. The descriptive data of patients were summarized. The continuous variables were summarized as mean ± SD and/or median, depending on the skewness of the data. The categorical variables were expressed as absolute numbers, frequency, and proportions (%). The data was tabulated and analyzed in Microsoft Excel 2019 version. A total of 20 patients who met inclusion criteria (probable or definite DRESS as per RegiSCAR criteria) were included in the study. The mean age of the patients was 41.2 ± 15.7 years. The average latency period was 26.45 ± 5.65 days (range: 7-60). The commonest culprit drugs were dapsone and phenytoin, each in five (25%) patients. Commonest morphology of rash was morbilliform in 13 (65%) patients. One patient with targetoid rash had multi-organ involvement. Facial edema, periorbital edema, and conjunctival injection were seen in 17 (85%), seven (35%), and six (30%) cases, respectively. Eosinophilia was present in 18 (90%) patients with mean (±SD) value of 1976 ± 840 cells/μl. Liver was the commonest internal organ involved in 14 (70%) patients and kidney in three (15%) patients. The initial dose of prednisolone for treatment varied from 0.75 to 2 mg/kg/day. The mean duration of steroid treatment was 64 ± 21 days. Two patients were treated with intravenous methylprednisolone and one with intravenous immunoglobulin. Two patients (10%) had recurrence of adverse drug reaction >6 months after completion of initial treatment and two (10%) developed autoimmune thyroiditis during follow-up. Small sample size and retrospective nature of the study were main limitations. Selection bias is a possibility as study was carried out in tertiary care center. Tests for incriminating culprit drugs such as patch test, intradermal test, and lymphocyte transformation test were not performed. DRESS is a rare disease that can be diagnosed early with high index of suspicion and treated successfully with steroids. The internal organ involvement is common in DRESS and requires a thorough evaluation.
