Clinical data on rare Sulfamethoxazole crystalluria assessed by Fourier Transform Infrared Spectrophotometry

The data contained in this article are related to the article entitled “Case report: Uncommon Sulfamethoxazole Crystalluria” [1]. Sulfamethoxazole crystalluria is very rare and crystals identification is complex [2], [3]. We identified seven patients with uncommon urine crystals that were composed of N-Acetyl-Sulfamethoxazole. Three of the patients developed an acute renal failure simultaneously to crystalluria. Hence, this article describes the method of crystals identification thanks to infrared spectroscopy. The relevant clinical data of patients, including medical history, drug dosage and urine parameters related to the crystalluria are presented.
