[Abstract]
We report a 66-year-old male who developed diabetic ketoacidosis (DKA) and necrosis of the small intestine due to non-occlusive mesenteric ischemia (NOMI), 3 months after starting quetiapine treatment. He was transferred to our hospital and diagnosed as diabetic for the first time, associated with DKA. Despite improvement in DKA, abdominal pain worsened gradually 10 h after hospitalization. Computed tomography (CT) revealed bowel emphysema, and gas out of the gut wall, in the mesenteric veins and the intrahepatic portal vein, suggesting intestinal necrosis. He survived because of resection of necrotic small-intestinal tissue and he finally required no diabetes treatment. Mesenteric arteries were patent with good palpitation without occlusion or thrombosis, and pathological findings showed ischemic enteritis, which is consistent with NOMI. DKA is a rare but serious side effect of second-generation antipsychotic medications (SGAMs) such as quetiapine, which can result in NOMI: a life-threatening complication. We must keep in mind that the plasma glucose concentration may increase in patients taking SGAMs, or that NOMI may occur concurrently if DKA develops.
