    Abstract:
    Umbilical veins (UV) and arteries (UA) of preeclamptic women in Curaçao harbor lower long-chain polyunsaturated fatty acids (LCP). The present aim was to test these findings in Mwanza (Tanzania), whose inhabitants have high LCPomega3 and LCPomega6 intakes from Lake Victoria fish. Women with preeclampsia (n=28) in Mwanza had lower PUFA and higher 20:0 in UV and UA, compared with normotensive/non-proteinuric controls (n=31). Their UV 22:6omega3, 22:4omega6, LCPomega6, omega6, and LCPomega3+omega6 were lower, while saturated FA, potentially de novo synthesized FA (Sigmade novo) and (Sigmade novo)/(LCPomega3+omega6) ratio were higher. Their UA had higher 16:1omega7, omega7, 18:0, and 16:1omega7/16:0. Umbilical vessels in Mwanza had higher 22:6omega3, LCPomega3, omega3, and 16:0, and lower 22:5omega6, 20:2omega6, 18:1omega9, and omega9, compared to those in Curaçao. Preeclampsia in both Mwanza and Curaçao is characterized by lower LCP and higher Sigmade novo. An explanation of this might be placental dysfunction, while the similarity of umbilical vessel FA-abnormalities in preeclamptic and diabetic pregnancies suggests insulin resistance as a common denominator.
