RESUMEN
Spontaneous bacterial peritonitis (SBP) is a recognized cause of morbidity and mortality in cirrhotic patients. Enterobacteriaceae have been isolated from the majority of peritonitis cases and the gram negative aerobe Escherichia coli is the most commonly isolated organism. Anaerobic organisms are rarely isolated because of the high oxygen tension in ascetic fluid. We report a patient with a history of alcoholic cirrhosis who developed SBP and concurrent bacteremia with the anaerobe Clostridium tertium. The patient was successfully treated with intravenous antibiotics and was discharged home on oral ciprofloxacin. This case report is unique in that it is the fourth documented Clostridium tertium SBP case, utilized MALDI-TOF mass spectrometry for organism identification, and susceptibility testing for select antibiotics was performed.
RESUMEN
Drug-induced neurotoxicity is a rare adverse reaction associated with ertapenem. Encephalopathy is a type of neurotoxicity that is defined as a diffuse disease of the brain that alters brain function or structure. We report a patient with normal renal function who developed ertapenem-induced encephalopathy manifesting as altered mental status, hallucinations, and dystonic symptoms. The patient's symptoms improved dramatically following ertapenem discontinuation, consistent with case reports describing ertapenem neurotoxicity in renal dysfunction. Since clinical evidence strongly suggested ertapenem causality, we utilized the Naranjo Scale to estimate the probability of an adverse drug reaction to ertapenem. Our patient received a Naranjo Scale score of 7, suggesting a probable adverse drug reaction, with a reasonable temporal sequence to support our conclusion.
