Introduction
DRESS syndrome is a rare, severe cutaneous adverse reaction that has been exceptionally described with NSAIDs. The objective of our study was to investigate the clinical, paraclinical, and epidemiological characteristics of DRESS syndrome associated with NSAIDs and to identify the implicated molecules.
Patients and methods
A retrospective descriptive study that included all cases of DRESS syndrome occurring with NSAIDs and reported over a 10-year period. Records were analyzed according to the RegiSCAR criteria for the diagnosis of DRESS and the French imputability method.
Results
We included 7 cases, with a female-to-male ratio of 1.33. The age of patients ranged from 18 to 75 years, with a mean of 55 years. The time to onset varied from 4 to 30 days, with a mean of 12 days. A fever equal to or greater than 38.5 °C was observed in 5 patients. All patients had skin involvement, mainly in the form of a maculopapular rash in 6 cases and erythroderma with glossitis in one case. Hypereosinophilia was found in 4 out of 7 patients. Hepatic involvement was observed in 4 patients, associated with renal involvement in 2 cases. One patient had isolated renal involvement. The NSAIDs implicated in DRESS syndrome in our patients were diclofenac, piroxicam, ketoprofen, and celecoxib.
Conclusion
Our study highlights the rarity and potential severity of DRESS syndrome associated with NSAIDs, due to systemic involvement. Clinicians should be vigilant about the possibility of DRESS syndrome with NSAID use, in order to promptly discontinue the implicated drug and ensure rapid management.
