Nutrition deficiencies are common in children with chronic liver disease. To determine whether age, hepatic dysfunction, or energy intake influences this malnutrition, we evaluated the nutritional status of 49 children aged 2.5 mo to 13 y (mean: 35 mo; median: 12 mo). The children were divided into two groups according to age: group 1-29 patients aged < or = 1 y (mean: 7 mo; median: 7 mo); and group 2-20 patients > 1 y (mean: 75 mo; median: 59 mo). Hepatic dysfunction was defined according to the Malatack criteria. Seventy-two-hour dietary intakes were recorded by a nutritionist. Nutritional status was assessed by anthropometric measures when the patients were enrolled on the waiting list for liver transplants. We evaluated the following indexes: weight, height, fat body mass, and lean body mass on the basis of height-age (age at which height reached 50th Italian height percentile). Mean height Z scores were low in both groups, but the difference was not significant. Mean weight Z scores and mean percentages of fat body mass were significantly lower (P < 0.001) in group 1 than in group 2 patients. In group 2, lean body mass and fat body mass were significantly lower (P < 0.05) in patients with moderate-to-severe hepatic failure than in patients with mild hepatic dysfunction. The mean energy intake was in the range of the recommended daily allowances for age but was insufficient for both groups of patients. The evidence of significant acute and chronic malnutrition confirmed the need for nutritional support, especially for younger and older children with moderate-to-severe hepatic dysfunction. We emphasize the necessity of accurate assessment of nutritional status by simple anthropometric measurements to be sure of the effects and adequacy of the nutritional intervention.
Fifty-five children with cholestatic cirrhosis due to extrahepatic biliary atresia received a course of hepatitis B vaccine. Forty-seven received a plasma-derived vaccine and eight a recombinant vaccine. Antibody determination was evaluated before and after liver transplantation in 30 patients. Twenty-five additional patients had antibody determination after transplantation only. Protection against hepatitis B was observed in 73.3% of the children evaluated prior to transplantation. One to 15 months after transplantation, 54.6% of all children studied showed protective levels of anti HBs. We conclude that hepatitis B vaccination is efficient in inducing immunity in the majority of children with cholestatic cirrhosis. Some patients will loose immunity under immunosuppression, but the protection rate remains higher than reported for patients vaccinated after transplantation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
