ABSTRACT

BACKGROUND: Liver disease is associated with increased levels of hyaluronic acid (HA). AIM: To evaluate serum HA concentrations in children with cirrhosis and its relation with liver function tests and Child-Pugh score. METHODS: Twenty-two children with biopsy-proven liver cirrhosis were studied. All were assessed for the presence of ascites or encephalopathy and liver function tests were performed. Patients were categorized according to Child-Pugh criteria. Serum HA was measured using microELISA (normal 0-100 ng/mL). Twenty-two children with chronic hepatitis B and no cirrhosis were studied as controls. RESULTS: Serum HA level in the cirrhotic children was 85.2 (72.8) ng/mL; levels were high (166.0 [46.3] ng/mL; range 115-246) in 8 (36.4%) patients. Three of 11 (27.2%) Child-Pugh class A patients, 3 of 8 (37.5%) class B patients, and 2 of 3 (66.7%) class C patients had elevated serum HA values (p=ns). Serum HA levels correlated with direct bilirubin level. The control group had lower levels (4.8 [2.3] ng/mL; p< 0.05), which were in the normal range. CONCLUSION: Serum HA level may be useful as a diagnostic tool in children with cirrhosis.

ABSTRACT

BACKGROUND AND AIM: Celiac disease (CD) is a gluten-induced enteropathy that results in malabsorption of nutrients. We studied the serum levels of carnitine and selenium in children with CD. METHODS: Serum levels of free carnitine and selenium were studied in 30 children (mean age 8.1 [4.4] years) with CD and 30 age- and gender-matched healthy children. All patients had type 3 duodenal lesions. The mean (SD) serum levels of free carnitine and selenium were lower among patients with CD (24.5 [7.7] micromol/mL and 52.1 (12.9) micromol/mL, respectively) than among healthy controls (29.4 [9.2] and 65.1 [17.2] micromol/mL; p < 0.05 each). Levels were similar in children with and without diarrhea. CONCLUSIONS: Serum carnitine and selenium levels are decreased in children with CD, probably due to malabsorption.

ABSTRACT

BACKGROUND: Wilson's disease (WD) is an autosomal recessive disorder with variable clinical presentation. Its diagnosis depends on a combination of clinical and laboratory findings. We evaluated the sensitivity of various diagnostic tests in children with WD and high liver copper concentrations. METHODS: Thirty-three children (6-15 years old, 19 male) with confirmed WD (hepatic copper >250 mcirog/g dry weight) were evaluated retrospectively. Eyes were examined with biomicroscope for Kayser-Fleischer rings and urinary copper content was determined in 30 patients. Serum ceruloplasmin levels were measured and liver tissue samples were stained with orcein in all. RESULTS: All patients presented with hepatic disease. Four patients also had neurological involvement. Hepatic copper concentration was between 250 and 1200 microg/g. Eighteen patients had liver cirrhosis, 9 chronic hepatitis, and 6 had massive hepatic necrosis on liver biopsy or necropsy. The sensitivity of various tests evaluated was: 100% (30/30) for urinary copper excretion, 88% (29/33) for orcein staining on liver tissues, 82% (27/33) for ceruloplasmin levels, and 63% (19/30) for presence of Kayser-Fleischer ring. Kayser-Fleischer ring was present in all patients with neurological manifestations and in 58% of patients with only hepatic presentation. CONCLUSIONS: 24-hour urinary copper excretion seems to be the most sensitive test for diagnosis of WD, particularly when liver biopsy cannot be performed due to coagulation abnormalities.
