[Platelet dysfunction and pregnancy in gestational exacerbation of chronic glomerulonephritis]
Aim:
To evaluate platelet dysfunctions and pregnancy outcomes in females with gestational exacerbation of chronic glomerulonephritis (CGN) and the disease remission.
Materials And Methods:
Platelet metabolism was studied by activity of intraplatelet LDG, platelet secretory activity by plasm beta-TG and ADP-aggregation in 75 gravidae. Of them 16 had exacerbation of CGN, 40 females were in remission of CGN and 19 healthy pregnant women served control.
Results:
Enhanced LDG activity and intensity of maximal ADP aggregation, high beta-TG levels compared to control were recorded in gravidae with CGN both in exacerbation and remission. The frequency of preterm deliveries, intrauterine growth retardation, neonatal hypotrophy was greater in women with gestational exacerbation of nephritis compared to pregnant women with stable nephritis.
Conclusion:
Metabolic and functional platelet hyperactivity with platelet intravascular activation in pregnancy in aggravated CGN suggest contribution of platelets to onset of the disease gestational exacerbation. Pregnancy-induced overactivation of platelets in CGN exacerbation stimulates intravascular coagulation in placental circulation with resultant microthrombi in placental vessels responsible for high rate of unfavorable pregnancy outcomes in relevant patients.
