SORIA DE GONZALEZ, Analía et al. Biochemical alterations in individuals consuming high levels of arsenic in drinking water in Tucuman, Argentina. Acta bioquím. clín. latinoam. [online]. 2009, vol.43, n.4, pp.611-618. ISSN 0325-2957.
The aim of this study was to investígate the relationship between the levels of serum sialic acid (S) and hepatic enzymes in individuáis who drink As contaminated water. Two hundred individuáis were selected: 85 were the control group, 32 presented hepatomegaly (I with H) and 83 did not present hepatomegaly (I without H) who had consumed drinking water containing As levels higher than O.Ol mg/L. Blood samples were collected for the determination of S and hepatic enzymes in serum: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (FAL), gamma glutamil transpeptidase (GGT), direct (BD) and total bilirrubin (BT), lactate deshydrogenase (LDH) and 5'nucleotldase (5'Nu). The populatlon exposed to As in drinking water presented high levels of S, FAL, GGT, LDH and GGT, LDH were increased in I with H and I without H respectively. No significant changes were observed in the other parameters studied. Prevalence of hepatomegaly was not significantly higher and the hepatic biochemical changes were related with the presence of cholestasis in As-exposed people. These data show that people with high As level intake would have an increased sialoprotein replacement which could be an marker with other one of the alterations caused by arsenic.
