OBJECTIVES: The objective of this study was to determine the maternal PLAC1 protein levels in early and late onset preec-lampsia. MATERIAL AND METHODS: A total of 135 pregnant women were included in the study, of which 55 were at < 34 weeks of gesta-tion and 80 were at ≥ 34 weeks of gestation, between June and November 2014 were recruited in this case control study. RESULTS: Analysis of maternal serum PLAC1 levels did not reveal any significant differences between early onset PE and controls (p = 0.422). However, late onset PE patients exhibited significantly elevated levels of PLAC1, in comparison with healthy controls (p = 0.026). The difference in PLAC1 levels between early onset PE and late onset PE was also significant (p = 0.001). Area under ROC curve of PLAC1 for early and late onset PE was 0.563 and 0.646 with p values of 0.422 and 0.026 respectively. Area under ROC curve of PLAC1 in PE was 0.613 with p value = 0.024. The cutoff value for PLAC1 was 6.19 ng/mL with sensitivity: 56% (95% CI 44.1-67.3) and specificity: 63 %; (95% CI 49.9-75.1) and diagnostic odds ratio: 2.2 (95% CI 1.1-4.4) (p value = 0.037). The cutoff value for PLAC1 was 7.2 ng/mL with sensitivity: 43% (95% CI 31.5-54.6) and specificity: 78% (95% CI 65.5-87.5) and diagnostic odds ratio: 2.69 (95% CI 1.25-5.79) (p value = 0.016) CONCLUSION: In conclusion, the results of the current study showed that PLAC1 protein levels were significantly elevated in pregnant women with late onset PE in comparison with healthy control group.
