Background Circulating levels of sFLT‐1 (soluble fms‐like tyrosine kinase 1), the extracellular domain of vascular endothelial growth factor (VEGF) receptor 1, and its ratio to levels of placental growth factor are markers of the occurrence and severity of preeclampsia. Methods and Results C57BL/6 pregnant mice on embryonic day 14.5 (E14.5), male, and non‐pregnant female mice were exposed to air or to Br 2 at 600 ppm for 30 minutes and were treated with vehicle or with VEGF‐121 (100 μg/kg, subcutaneously) daily, starting 48 hours post‐exposure. Plasma, bronchoalveolar lavage fluid, lungs, fetuses, and placentas were collected 120 hours post‐exposure. In Br 2 ‐exposed pregnant mice, there was a time‐dependent and significant increase in plasma levels of sFLT‐1 which correlated with increases in mouse lung wet/dry weights and bronchoalveolar lavage fluid protein content. Supplementation of exogenous VEGF‐121 improved survival and weight gain, reduced lung wet/dry weights, decreased bronchoalveolar lavage fluid protein levels, enhanced placental development, and improved fetal growth in pregnant mice exposed to Br 2 . Exogenous VEGF‐121 administration had no effect in non‐pregnant mice. Conclusions These results implicate inhibition of VEGF signaling driven by sFLT‐1 overexpression as a mechanism of pregnancy‐specific injury leading to lung edema, maternal mortality, and fetal growth restriction after bromine gas exposure.

To examine the role of VEGF in the pathogenesis of high-altitude pulmonary edema (HAPE), we measured the concentrations of VEGF in venous serum and bronchoalveolar lavage fluid in patients with HAPE and in healthy volunteers. The VEGF in venous serum of the patients was normal at admission and significantly increased at recovery. Similarly, the VEGF in bronchoalveolar lavage fluid of the patients was increased at recovery compared with admission, but values at both admission and recovery were significantly lower than those of the controls. The present finding suggests that VEGF probably is destroyed in the lung of HAPE, and it appears less likely to have a critical part in the pathogenesis of HAPE but has rather an important role in the repair process for the impaired cell layer.
