简要总结
Preeclampsia is characterized by the onset of hypertension and proteinuria or other signs of end-organ dysfunction after 20 weeks of gestation in a previously normotensive patient. Its pathophysiology involves abnormal placentation, an imbalance of prostaglandins, inflammatory mediators, oxidative stress, and an imbalance of angiogenic and anti-angiogenic proteins.
Hypertension and anemia are the common medical complications of pregnancy that contribute to maternal and perinatal mortality. So, identifying this condition as early as possible will bring a better outcome for pregnancy. Preeclampsia is defined as the new onset of hypertension and either proteinuria or other signs of end-organ dysfunction after 20 weeks of gestation in a previously normotensive patient.
The pathophysiology of preeclampsia is due to abnormal placentation, imbalance in different components of prostaglandins, inflammatory mediators, oxidative stress and imbalance of angiogenic and anti-angiogenic proteins.
Iron is an important element that causes oxidative stress and damage to endothelial cells. The need of iron, increases during pregnancy, deficiency (levels below 9.5- 10.5gm/dl ) of which leads to development of anemia and adverse maternal and fetal outcomes. And at the same time high serum iron levels are associated with preeclampsia. Serum ferritin is glycoprotein which is a primary form of iron storage and is the most effective indicator of iron status, in the absence of any infection or inflammation. Studies done by
Zhuanji Fang et al,which is the only study available estimating serum ferritin levels during early pregnancy has found that the risk of pregnancy related hypertensive disorders increase with increase in early pregnancy serum ferritin levels.
Total iron binding capacity increases and transferrin saturation decreases with decrease in serum iron levels and thus is useful marker for detecting iron deficiency anemia.
Presently only one prospective study done by Małgorzata Lewandowska et al, is available in which it was concluded that low serum iron levels estimated during early pregnancy were associated with preeclampsia.
Since the results were contradictory we would like to do a prospective study measuring the complete iron profile levels between 12-20 weeks of gestation to see what parameters correlates with development of preeclampsia.These parameters can also further be used as a biochemical predictor of preeclampsia and guide us regarding, whether routine prophylactic supplementation of iron is to be done or not.
