The objectives of this study were to estimate the prevalence of vitamin D deficiency in patients with acute coronary syndrome in comparison with normal individuals and study the correlation between these two conditions. We measured the plasma 25-hydroxy vitamin D (25-OH-D) levels in 60 patients with acute coronary syndromes (ACS) of both gender and in 30 age matched control individuals of both gender without any known cardiovascular or systemic diseases. The levels of 25-OH-D were measured by ELISA method and the results were statically analyzed to find out any possible correlation. We classified the cases according to their plasma 25(OH)D levels. 25(OH)D levels of ≥ 30 ng/ml were considered normal, levels < 30 and > 20 ng/ml were classified as insufficient, while levels of ≤ 20 ng/ml were classified as deficient. In the current study the prevalence of hypovitaminosis D in the patients group was much higher than it was in the control group. Vitamin D deficiency was observed in 80% and insufficiency in 13% of total patients of ACS, there by bringing the total count to 93%. Whereas only 7% of the patients had adequate vitamin D levels. Thus, these results indicate the existence of a significant correlation between the vitamin D deficiency and ACS in comparison to healthy controls

We aimed to assess the parathyroid hormone (PTH) concentration in pregnant women at the beginning of pregnancy (1st trimester) and within days before delivery (3rd trimester) and evaluate its determinants. From September 2014 through December 2015 in a cross-sectional study, 204 women in the 1st trimester of pregnancy and 203 women in the 3rd trimester of pregnancy were recruited. Blood samples were collected to measure PTH and circulating 25-hydroxy-vitamin D (25(OH)D) concentrations. Lifestyle and demographic data were collected using a questionnaire. Serum 25(OH)D and PTH were inversely correlated in both early and late pregnancy. Our analyses suggest that in the 3rd trimester of pregnancy, a 25(OH)D level of 18.9 ng/mL (47.3 nmol/L) could serve as an inflection point for the maximal suppression of PTH. Statistically significant determinants of PTH concentrations in multiple regression were 25(OH)D concentrations, season, multiparity and education of the partner (all p < 0.05) in early pregnancy. In late pregnancy, 25(OH)D concentrations and country of origin were statistically significant determinants of PTH concentrations (all p < 0.05). These factors and their effect on PTH appear to be vastly determined by 25(OH)D; however, they might also affect PTH through other mechanisms besides 25(OH)D.
