Abstract

Thiopurines by their glucocorticoid-sparing property help in maintaining remission for patients with inflammatory bowel disease (IBD), when glucocorticoids are reduced and withdrawn. However, due to bone marrow suppression, it cannot be used in various conditions where it is indicated. A 17-year-old patient presented with pancytopenia with neutropenic sepsis and alopecia after 3 weeks of starting azathioprine for her underlying Crohn\'s disease. Thiopurine S-methyltransferase (TPMT;*2, *3A, *3C) analysis resulted in a wild-type genotype, whereas homozygous Nudix hydrolase 15 (NUDT 15 C415T) variant was positive. Azathioprine was stopped immediately, and she was started on broad-spectrum antibiotics that led to some clinical improvements initially, but later on, the patient developed intestinal obstruction along with postoperative complications leading to death. In this report, we highlight a case of serious hematological toxicity associated with azathioprine use in a patient with Crohn\'s disease with homozygous NUDT 15 variant, thus favoring the implementation of a pharmacogenomic approach before starting azathioprine, particularly in the Asian population.
