Nutritional status and growth in children with chronic hepatitis B.

As reported for other chronic liver diseases, hepatitis B virus (HBV) chronic infection might result in malnutrition. In order to establish whether this disease could be responsible of malnutrition and hence influence growth, 75 children, chronically infected with HBV, have been followed up for 4 years. Thirty-one of them had chronic active hepatitis (CAH), 25 chronic persistent hepatitis (CPH), 14 chronic lobular hepatitis (CLH), and five cirrhosis (three active, two inactive). The nutritional status was evaluated every 12 months, with careful physical and laboratory examinations. General nutritional status was estimated according to Waterlow criteria (13, 14). At our first observation, 50 children were following a balanced diet with a caloric intake adequate for age and weight, whereas 25 were on a low-fat diet, begun in the belief of its therapeutic value. For seven patients of this second group, the caloric intake was below the daily requirement. The latter group showed a growth failure in weight when they were first seen at our center and gained weight when the dietary intake was normalized. However, no biochemical feature of malnutrition was observed in all the 75 children. At the end of the follow-up period, the nutritional status was satisfactory for all of them.
