Biochemical Assessment of Pregnancy-Related Physiological Changes in Renal Function

Abstract

This study was aimed at determining biochemical markers of renal function in pregnant women in Kano State, Nigeria. Urea, electrolytes and creatinine were estimated from 45 pregnant women and 45 non pregnant apparently healthy, age-matched controls.  The result of the study showed significant difference (P<0.01) in urea, creatinine and bicarbonate levels between the pregnant and non- pregnant women but no significant difference (p>0.01) was observed in sodium, potassium and chloride levels between the two groups. Studies within the trimesters showed significant difference (p<0.05) in urea levels between the control group of the 1st and 2nd trimesters. Creatinine levels in the 2nd trimester (43.20±12.3) and 3rd trimester (41.40±5.45) were found to be significantly lower (p<0.05) compared to the control group (55.84±16.17). A significant difference in creatinine levels (p<0.05) between the 1st and 2nd and the 1st and 3rd trimesters was also recorded. The mean difference in bicarbonate levels in the 1st (22.33±1.84), 2nd (21.80±1.37) and 3rd(21.73±1.79) trimesters and the -control group (26.09±2.08) was significantly lower (p<0.05) with no significant difference within the trimesters. There was no significant difference (p>0.05) observed in sodium, potassium and chloride level between the control groups and the trimesters of pregnancy. The result obtained is indicative of normal renal function in the study groups
