RESUMO

PROBLEM: Preeclampsia (PE), a multifactorial disorder characterized by impaired placental development, elevated inflammatory response and dysregulated placental steroidogenesis. PE may be preventable if predicted early on. METHOD OF STUDY: The study evaluated the potential of immunomodulatory collectins, surfactant protein A (SP-A), surfactant protein D (SP-D), and mannose binding lectin (MBL), to predict PE before the disease onset, in a prospective study cohort of healthy pregnant women (n = 922). In addition, a cross-sectional study was conducted to determine the serum and placental profile of collectins in PE women after the disease onset (early-onset PE [EOPE], n = 33; late-onset PE [LOPE], n = 24); and controls [n = 75]. The serum profiles of estradiol (E2) and progesterone (P4) were evaluated to determine their correlation with collectins. RESULTS: In the prospective cohort, significantly decreased serum levels of SP-A, SP-D, P4/E2 ratio were observed in women who subsequently developed severe EOPE. Interestingly, after the disease onset, there was a significant increase in serum and placental levels of collectins in women with severe EOPE, whereas women with LOPE had significantly decreased levels of collectins. Serum P4/E2 ratio was significantly altered in severe EOPE and positively correlated with serum levels of SP-A and SP-D. CONCLUSION: Collectins are differentially expressed in the serum during progression of PE. Decreased serum levels of SP-A, SP-D, P4/E2 ratio and increased E2 during 10-20 weeks of gestation are novel plausible risk factors for early prediction of EOPE in Indian women.
