Low vitamin D may explain the link between preeclampsia and cardiovascular disease
Article Outline
Sir:
The recent review and meta-analysis of cardiovascular sequelae of preeclampsia found large increases in risk of cardiovascular diseases for those who suffered preeclampsia and an increased risk with increasing severity of preeclampsia.1 Preeclampsia is also associated with increased risk of cancer.2 I would like to suggest that the link is low serum 25-hydroxyvitamin D (25[OH]D), which has been reported as a risk factor for preeclampsia3 as well as for cardiovascular disease.4, 5 Serum 25(OH)D levels are associated with important cardiovascular disease risk factors in US adults.6 Low serum 25(OH)D is also an important risk factor for many types of cancer.7 It has been suggested that pregnant and nursing women should be taking 4,000 to 6,000 IU/d of vitamin D.8 For optimal health in general, serum 25(OH)D levels should be >32 ng/mL (80 nmol/L).9 One thousand international units per day raises serum 25(OH)D by about 10 ng/mL.9
