Background: PV and ET have high predisposition to thrombosis and recurrence of thrombosis. We determined VEGF, D-dimer and coagulation activation markers in clinically stable patients and recurrence of thrombosis. Methods: Thirty-five Indonesian patients diagnosed with PV and ET and under treatment for the disease were recruited. The following assays were performed: VEGF, D-dimer, fibrinogen, TAT-complex, vWF, β-TG and JAK2 V617F mutation. Data between patients who were clinically stable (n=20) and those with recurrent thrombosis (n=15) at the time of study was analysed. Results: The mean age for PV/ET was 51.7 ± 14.9 years. Thrombosis episode was recorded for 94.3% (33/35) patients. Twenty (57.1%) clinically stable and 15 (42.9%) patients had recurrence of thrombosis. D-dimer (P=<0.001), fibrinogen (P=0.005) were statistically significant and VEGF (P=0.06) were seen in recurrence of thrombosis compared to clinically stable patients who had normal D-dimer. Elevated D-dimer seen in recurrence thrombosis was significantly correlated with VEGF (P=0.002) levels. Elevated VEGF were seen in 45% of clinically stable patients and 73.3% in recurrence of thrombosis.
