Hepatopathy in two infants with short-bowel syndrome and cytomegalovirus infection.
In children with short-bowel syndrome and the need for long-term parenteral nutrition, hepatic dysfunction is a multifactorial phenomenon that has not been completely understood. Alterations in gut motility lead to intraluminal stasis which is thought to be a major etiologic factor for bacterial overgrowth and subsequent cholestasis, especially when the ileocecal valve is absent. We report on two infants with short-bowel syndrome caused by gastroschisis and intestinal atresia. The intestinal lengths after resection were 18 and 55 cm. Long-term parenteral nutrition (PN) was obligatory due to intestinal shortness in the first patient and dilatation of the preatretic bowel segment with ineffective peristalsis in the second patient. Despite multiple trials of enteral nutrition and medical therapy for gut decontamination and stimulation of bowel motility, hepatopathy developed in both patients in a similar period of time and to about the same degree. At the age of 4 and 6 weeks, respectively, increasing bilirubin values were measured. Deterioration of liver function and thrombocytopenia at the age of 3 to 4 months led to the diagnosis of acute cytomegalovirus (CMV) infection. Treatment with ganciclovir followed. Both patients died of acute liver failure at the age of 7 and 9 months, respectively. Additional hepatic injury secondary to CMV infection might have contributed to the rapid deterioration of liver disease. Screening for further hepatotoxic factors, especially infectious etiologies, is therefore recommended in children with short-bowel syndrome. Liver transplantation should be considered early in cases of progressive hepatic dysfunction.
