A59 SEVERE CHEMOTHERAPY-INDUCED SECRETORY DIARRHEA
Notice bibliographique
Résumé
Abstract Background Diarrhea is one of the most common side effects of chemotherapy, estimated to occur in up to 40% of all patients undergoing cancer therapy. Non-complicated chemotherapy-induced diarrhea (CID) can be managed with loperamide, whereas complicated CID should be treated with continuous infusion of octreotide. Octreotide is usually effective within 48hs of administration. Options for patients that do not respond to loperamide or octreotide include atropine, oral budesonide and cholestyramine. Aims To describe the case of an 18 yo girl with acute myeloid leukemia (AML) who developed severe secretory diarrhea during her treatment course. Methods Retrospective case report. Results The patient was initially treated with Cytarabine, Daunorubicin and Etoposide, and on her third cycle, Gemtuzumab was added. Four weeks later she presented with watery diarrhea up to 6 L/day. She continued with high output despite no oral intake, which was consistent with secretory diarrhea. Infectious workup was negative, and she received Loperamide. Her output decreased to 1 L for 2 days but then increased again to 6 L. She deteriorated and loperamide was switched to octreotide 0.8mcg/Kg/h. The dose was increased to 1.2mcg/Kg/h and she presented blood in the stools. Her stool output was still 4 L/day and octreotide was stopped after one week. Flex sigmoidoscopy showed proctocolitis with friability. Biopsy showed architectural distortion with loss of the superficial epithelium. She was emotionally distressed due to many days of no oral intake, hence Pediasure peptide was introduced, with no changes in the output. Rice was introduced but her diarrhea worsened, and oral intake was stopped again. Four weeks after the onset of diarrhea, her stool output was still above 2 L/day, and cholestyramine 4g once daily was started. Four days later her output decreased and diet was slowly introduced. Two weeks later she had a normal stool output. Cholestyramine was stopped and she was discharged home. Finding the culprit for this case is a challenge, but important to avoid this drug in the future as prior history of CID is a risk factor for a new-onset. Gemtuzumab is a relatively new anti-CD33 antibody used in AML, and results from a meta-analysis showed that adding it to induction chemotherapy may increase the incidence of diarrhea. Her diarrhea started four weeks after the dose of Gemtuzumab, and we believe this new agent might have played an important role in her case. To our knowledge, there are no cases in the literature associating Gemtzumab with such prolonged and severe diarrhea. Conclusions This was a challenging case of CID that did not respond to Loperamide or octreotide and caused a lot of emotional distress for the patient and her providers. Since she responded well to cholestyramine, we recommend its use when the loperamide and octreotide have failed, or in addition to octreotide in severe cases. Funding Agencies None
