A 10-month-old with rotavirus gastroenteritis, seizures, anasarca and systemic inflammatory response syndrome and complete recovery.

This report describes a 10-month-old infant who presented with generalised tonic clonic seizures following 2 days of vomiting, diarrhoea and a low-grade fever. The patient was moderately dehydrated and the blood investigations were remarkable for hyponatraemia (126 mEq/l), leukocytosis (19.4 × 10(3)/l (46% lymphocytes)), thrombocytosis (637 × 10(3)/l), hypoalbuminaemia (albumin 1.9 g/dl) and elevated C reactive protein (96 mg/l). Stool was positive for white and red blood cells but the cultures for bacteria were negative. Rotavirus antigen in stool was positive. There was microscopic haematuria without proteinuria and the nasogastric aspirate was coffee ground. Generalised oedema with pleural and peritoneal effusions ensued requiring drainage, correction of fluid and electrolytes imbalance and albumin infusions. Over the next 72 h, the patient descended into shock and disseminated intravascular coagulopathy which required packed red blood cells and fresh frozen plasma transfusions. By day 12 the patient was clinically and biochemically normal.
