Abstract | OBJECTIVE: METHODS: Serum was collected and the angiogenic biomarkers of patients with ITP and gestational thrombocytopenia (N = 9) were compared to patients with HELLP (N = 11) and PE (N = 11). Circulating levels of these angiogenic biomarkers were also compared by gestational age to 1564 randomly selected normotensive women from the Calcium for Preeclampsia Prevention study. RESULTS: Patients with non-HELLP thrombocytopenia had lower sFlt1 (7.3 +/- 3.8 ng/ml vs. 15.5 +/- 5 ng/ml, P < 0.001), lower sEng (8.7 +/- 3.6 vs. 34 +/- 17, P < 0.001) and higher PlGF (484 +/- 412 vs. 66.3 +/- 44, P = 0.003) than patients with HELLP syndrome. Angiogenic factor abnormalities in patients with PE were similar to patients with HELLP syndrome, suggesting a common pathogenesis. Patients with non-HELLP thrombocytopenia had angiogenic profiles similar to normotensive controls, whereas patients with HELLP syndrome had levels higher than the 90th percentile for sFlt1 and sEng and lower than the 10th percentile for PlGF. CONCLUSIONS: Angiogenic biomarkers may be useful in excluding conditions that mimic PE.
