sFlt-1, PlGF, sFlt-1/PlGF ratio and uterine artery Doppler for preeclampsia diagnostics
Materials and methods: We performed a case controlled study of 72 pregnant women with preeclampsia and 72 healthy matched controls. SFlt-1 and PlGF were measured in serum samples, the sFlt-1/PlGF ratio was calculated and UA pulsatility (PI) and resistance (RI) indexes were registered.
Results: Significantly higher levels of sFlt-1, sFlt-1/PlGF ratio and mean UAPI and UARI and lower levels of PlGF were found in preeclampsia group when compared to controls. The highest sensitivity and specificity for preeclampsia had SFlt-1/PlGF and PlGF with the cut-off values of ≥35 (sensitivity of 95.8% and specificity of 96.2%, respectively) and ≤138.6 pg/mL (sensitivity of 95.8% and specificity of 93.7%, respectively). For diagnostics of early-onset preeclampsia, all factors sFlt-1, PlGF and sFlt-1/PlGF had equal significance with the cut-off values of ≥7572 pg/mL (specificity of 97.5%, sensitivity 92.3%), ≤100.5 pg/mL (specificity 96.2%, sensitivity of 100%) and ≥54.6 (specificity 97.5%, sensitivity 97.5%) respectively.
Conclusions: The sFlt-1/PlGF ratio and PlGF are superior to sFlt-1, UAPI and UARI for preeclampsia diagnosis. For early-onset preeclampsia diagnostics either sFlt-1 or PlGF is sufficient.
