Abstract


Background: One of the features associated with pre-eclampsia is elevated liver transaminases. The reason this happens has not been fully described. However, the hepatocytes are not known to be spared by free radical injury. This study was conducted to examine the relationship between product of free radical injury (malondialdehyde) and transaminases in pre-eclamptic women.

Patients and methods: A total of 98 and 115 pre-eclamptic and apparently normal pregnant women were selected from the booking clinic of Ladoke Akintola University of Technology Teaching Hospital, Osogbo. Non-pregnant women were selected from volunteered members of staff. Malondialdehyde (MDA), aspartate transaminase (AST) and alanine transaminase (ALT) analyses were determined on collected venous blood sample. Statistical analyses of variables were done using SPSS 17 taking level of significance to be p<0.05.

Results: Subjects with plasma AST between 10 and 20U/L had mean plasma MDA of 0.92μmol/l whereas those with plasma levels greater than 41U/L had mean plasma MDA of 4.72μmol/l. Similarly, Subjects with plasma ALT between 10 and 20U/L had mean plasma MDA of 0.86μmol/l, and subjects with plasma ALT greater than 51 U/L had mean plasma MDA of 4.71μmol/l. Positive correlation was observed between AST and ALT(r=0.79;p=0.047), between AST and MDA(r=0.690; p=0.061) as well as between ALT and MDA(r=0.571;p=0.049).

Conclusion: The elevated liver enzymes seen in women with pre-eclampsia may be due to free radical injury to the liver. Pre-eclamptic women without free radical injury did not have elevated transaminases

Keywords: Pre-eclempsia, free radical, malondialdehyde, alanine and aspartate aminotransaminases
