Azathioprine-related myelosuppression in a patient homozygous for TPMT*3A.

Pooja Budhiraja1, Mordecai Popovtzer.   

Abstract

BACKGROUND: A 50-year-old man who had received a simultaneous pancreas and kidney transplant 9 years earlier developed pancytopenia 3 weeks after starting azathioprine therapy to treat worsening proteinuria suspected to be caused by sirolimus. INVESTIGATIONS: Laboratory tests, including complete blood counts, measurement of serum levels of vitamin B(12) and folate, liver function tests, virological assays, and thiopurine S-methyltransferase (TPMT) genotyping. DIAGNOSIS: Severe myelosuppression as a consequence of azathioprine therapy in a patient homozygous for the TPMT*3A allele. MANAGEMENT: Discontinuation of azathioprine, treatment with an erythropoiesis-stimulating agent, red blood cell transfusions, filgrastim (a granulocyte colony-stimulating factor analogue) and folic acid.
