Flaccid quadriparesis associated with Yersinia enterocolitis-induced hypokalemia

Arch Intern Med. 1989 May;149(5):1193-4.


A 23-year-old woman presented with diarrhea, flaccid quadriparesis, a low serum potassium level, and an elevated creatine kinase level. A stool culture yielded Yersinia enterocolitica, and a muscle biopsy was compatible with a hypokalemic myopathy. The patient's diarrhea responded to sulfamethoxazole and trimethoprim therapy. We suggest that Y enterocolitica be added to the group of intestinal pathogens capable of producing hypokalemia and rhabdomyolysis.
