Variation In Thiopurine Metabolism In Hispanic Children, Kayeleigh Higgerson Do

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Overall survival rate is > 90% in the United States. However, ethnic and racial disparities remain. Hispanic patients have an inferior overall survival compared to non-Hispanics. The reasons for these differences remain unclear. Mercaptopurine (6MP) is a crucial drug in ALL treatment. Variations in the TMPT and NUDT15 genes lead to altered 6MP metabolism and accumulation of toxic metabolites (6TGN or 6MMPN). Each metabolite is associated with specific dose-limiting toxicities. The accumulation of 6TGN causes myelosuppression, and increased 6MMPN causes GI toxicity. While variants in these genes have been identified …

Background: Wilm’s Tumor (WT) is the most common renal malignancy of childhood. The initial presentation of WT may mimic infection or other malignancies with nonspecific symptoms including fever, abdominal/flank pain, or hematuria. This poses a diagnostic challenge for providers, particularly when both infection and malignancy are observed. We describe a case of WT with spontaneous necrosis initially obscured by overlying Clostridium perfringens infection, making diagnosis of the cancer difficult.
Case Description: A previously healthy 5-year-old girl presented to the emergency department with a two-day history of left flank pain and fevers. In the emergency department, she was tachycardic (130 bpm), …
