RESUMO
Sub endothelial infarcts leads to non-ST-elevation acute coronary syndrome. Proinflammatory cytokines are raised in serum, the severity of which is a poor prognostic sign. Vitamin D deficiency is prevalent among patients of ACS. Vitamin D has immunomodulatory roles having effects on various aspects of inflammation. A total of 40 patients were divided into experimental (n=20) and control (n=20) groups. Experimental group was given single dose of vitamin D 200,000 IU. They were assessed for baseline C-reactive protein, interleukin-6, tumor necrosis factor-α levels by using sandwich ELISA technique. Four months after intervention resampling was done for the same parameters. Findings were expressed as mean±SD. Independent sample t-test was used to compare effect of vitamin D intervention between control group and intervention group. p-value of ≤0.05 was considered to be significant. The serum C-reactive protein showed significant reduction (p=0.028*) after intervention with vitamin D. Serum interleukin-6 (p=0.848), tumor necrosis factor-α (p=0.20) were decreased non-significantly in experimental as compared to the control group. It was concluded that a single large dose of vitamin D was able to reduce the C-reactive protein in non-ST-elevation acute coronary syndrome patients while non-significant reductions in interleukin-6 and tumor necrosis factor-α were observed.
