Study Design: This is a case-control study that took place during the period from September 2014 to March 2015 in four quaternary and tertiary maternity hospitals in Kinshasa. A total of 113 healthy pregnant women (controls) and 112 pre-eclamptic and eclamptic pregnant women (cases) were included in this study. Seric calcium and magnesium were measured in all these gravidas by the principle of spectrophotometry with a HUMALYSER Primus semi-automaton. Results: The mean age of those gravidas was 26.8 ± 6.3 years (26.7 vs 26.9, p = 0.11). The majority of these gravidas were primiparous. The mean gestational age in both groups was 31.35 ± 0.9 weeks (32.1 vs 30.6, p = 0.21). The average seric calcium value was 4.47 ± 0.23 mEq /L in healthy pregnant women compared to 3.80 ± 0.71 mEq/l in pre-eclamptics (P 0.001). The mean of seric magnesium was 1.56 ± 0.15 mg/dL in healthy pregnant women compared to 1.20 ± 0.41 mg/dL in pre eclamptics (P 0.001). Seric calcium and magnesium values were low in the pre-eclamptic group and lower in the eclamptic group (P 0.001). Conclusion: This study establishes a relationship between the low concentration of seric calcium and magnesium with pre-eclampsia and eclampsia, which could be one of the determinants of the high prevalence and seasonality of the disease in Kinshasa.展开更多
