Abstract
The clinical course of a patient with chemotherapy-related diarrhea (CRD) refractory to standard therapy was monitored over the course of 21 days. The patient was minimally responsive to traditional treatment options, including bismuth subsalicylate, diphenoxylate-atropine, loperamide, octreotide, and oral (PO) steroids, and exhibited reportable improvements with the addition of intravenous (IV) methylprednisolone to other antidiarrheal agents. We present a case of CRD in an 82-year-old female. She was initiated on chemotherapy three weeks prior and has experienced severe diarrhea since her initiation. Despite the use of first-line antidiarrheal therapies, including loperamide, diphenoxylate-atropine, and octreotide, both subcutaneously and via continuous infusion drip, no infectious cause was found. She also received the non-absorbing corticosteroid budesonide, but her diarrhea persisted. After experiencing severe hypotension and hypovolemia secondary to profuse diarrhea, she was placed on IV steroids, which quickly reduced her symptoms. The patient was then transitioned to oral steroids and discharged on a tapering regimen. We recommend using IV steroids to treat CRD if first-line therapies fail. Utilizing IV steroids efficiently and effectively can decrease the symptoms of persistent diarrhea and lead to rapid recovery.
