Acute encephalopathy associated with nontyphoidal salmonellosis.
The importance of an acute encephalopathy associated with nontyphoidal salmonellosis has recently been recognized, but the disease entity has been poorly established. In this study, we describe two encephalopathic patients associated with nontyphoidal salmonellosis. The patients exhibited a rapid evolution of coma after the onset of lethargy or seizure. Fever and diarrhea due to salmonellosis preceded these events. Secondary factors inducing encephalopathies, such as severe dehydration, sepsis, meningitis, electrolyte or metabolic disturbances, acute renal failure, and multiple organ failure, were excluded in the differential diagnosis at the onset of encephalopathic features. These clinical findings and rapid development of encephalopathic features from localized intestinal infection without any significant abnormalities in a variety of blood tests may suggest a toxic etiology. However, endotoxin was not found in serum from both patients. From these results, we conclude that nontyphoidal salmonellosis can cause a toxic encephalopathy syndrome, like shigellosis or verocytotoxin-producing Escherichia coli infection.
