Introduction And ObjectivesPrevious observational studies have suggested that low vitamin D status is associated with high circulating C-reactive protein levels, as well as other plasma inflammatory cytokines. However, there is no study to explore the relationship between vitamin D status and Lp-PLA2, a new biomarker of vascular-specific inflammation. The aim of this study was to examine the association between vitamin D status and circulating Lp-PLA2 levels in subjects with type 2 diabetes mellitus.Material And MethodsThis descriptive cross-sectional study enrolled diabetic subjects who underwent physical examination at Taizhou People's Hospital between August 2016 and January 2017. Blood pressure, anthropometry, metabolic profiles, serum 25(OH)D levels and Lp-PLA2 mass levels were measured in all participants.ResultsA total of 196 participants were recruited into this study. The vitamin D insufficiency group had higher serum LP-PLA2 levels than the vitamin D sufficiency group (t=-2.765, p=.005). A significant negative correlation was noted between Lp-PLA2 and 25(OH)D in the vitamin D insufficiency group (r=-0.364, p=0.009). However, no significant relationship between serum Lp-PLA2 concentration and 25(OH)D levels was observed in subjects with vitamin D sufficiency.ConclusionsFrom this cohort of patients with type 2 diabetes, regardless of traditional cardiovascular risk factors, we observed a statistically significant inverse relation between Lp-PLA2 and 25(OH)D at levels <30ng/mL.Copyright © 2019 Elsevier España, S.L.U.
