Preeclampsia, preterm birth, Trichrome stain, TNF- αAbstract
Preeclampsia (PE) is a significant contributor to maternal morbidity and mortality that manifests as new-onset hypertension after 20 weeks of pregnancy with signs of uteroplacental or maternal organ dysfunction or proteinuria. This condition is linked to intrauterine growth restriction, preterm birth, placental abruption, fetal distress, and fetal death in utero. The findings of the recent study can be summed up as follows: Hematoxylin and eosin staining of placenta tissues revealed a significant area of calcification in the villous stroma. Additionally, increased collagen fibers around blood vessels and varying degrees of mononuclear cell infiltration are caused by capillary and vein congestion. The Masson's Trichrome stain revealed deposited fibrin between decidual cells and extra-villous cytotrophoblasts, which were surrounded by mature intermediate and terminal villi. Congestion of veins with increased fibrin deposits around veins and arterial vessels with increased fibrocytes When the data was statistically analyzed, it was discovered that PE pregnant women had significantly p<0.05 higher levels of serum TNF- α , than normotensive women ( NT ). Finally, the study found a link between preterm PE and women's pregnancy, as well as histopathologic and immunological parameters in preterm PE and NT women.
