title: Water-soluble vitamins in severe liver disease.
abstract: Biochemical deficiency of thiamine, vitamin B6, ascorbic acid or nicotinic acid occurred in 71% and 88% of patients with fulminant hepatic failure (FHF) and decompensated chronic liver disease (DCLD) respectively. Transient high plasma vitamin B6 concentrations in FHF were followed by low levels later in the illness. Although patients with DCLD of alcoholic aetiology tended to have lower circulating levels of vitamins than those with non-alcoholic DCLD, the prevalence of abnormally low concentrations did not differ. Decreased dietary nutrient intake and alcohol appeared to be less important determinants of biochemical vitamin deficiency than the presence of liver disease per se. Finally, urinary excretion of these vitamins or their major metabolites in patients with severe liver disease correlated poorly with circulating levels of vitamins.
