Trimethoprim-sulfamethoxazole (TMP-SMX) is a bacteriostatic antimicrobial medication used for the treatment of a variety of infections and has many reported skin and hematologic side effects. Due to the easy availability and cost effectiveness, TMP-SMX is one of the medications commonly used for treatment of skin and soft tissue in patients with methicillin-resistant Staphylococcus aureus (MRSA) infection. One of the rare hematologic manifestations of TMP-SMX is pancytopenia, which is a reduction in all cell lines. In this case report, we are documenting a case of pancytopenia due to severe drug reaction to TMP-SMX in a 70-year-old female after two weeks of medication use. Upon initial stabilization she underwent a thorough workup and was subsequently diagnosed with severe drug-induced pancytopenia. Detailed history, early diagnosis, prompt discontinuation of the offending medication along with supportive care remain the mainstay of treatment in the management of TMP-SMX induced pancytopenia.
Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding that is often associated with chronic pancreatitis. The bleeding usually manifests as melena because the source originates superior to the ligament of Treitz. We present a patient who was admitted for acute-on-chronic pancreatitis and ultimately developed hematochezia. Endoscopy revealed active oozing at the minor duodenal papilla. Computed tomography angiography identified active contrast extravasation at the gastroduodenal artery, and it was managed successfully with angioembolization. Our case emphasizes clinicians to consider hemosuccus pancreaticus as an alternative differential in a patient with a history of chronic pancreatitis manifesting with hematochezia.One week after the endoscopy, the patient developed multiple episodes of bright red blood per rectum. Her hemoglobin dropped to 6.9, which was below her baseline of 9 g/dL. Colonoscopy performed because of suspected lower GI bleeding only revealed polyps and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
