Randomized controlled trial of vitamin d supplementation on toll-like receptor-2 (tlr-2) and toll-like receptor-4 (tlr-4) in tuberculosis spondylitis patients

Abstract

Abstract Background Tuberculosis spondylitis accounts for approximately 50% of all cases of skeletal tuberculosis. Vitamin D plays a role in the immune system. Vitamin D helps in the activation of TLR-2 and TLR-4, which play a role in the process of tuberculosis infection. The objective of this study was to investigate the effect of oral supplementation with vitamin D on TLR-2 and TLR-4 levels in tuberculosis spondylitis patients. Methods The true Experiment Design Pretest–Posttest with Control Group (Pretest–Posttest with Control Group) was used for this research. TLR-2 and TLR-4 were measured by ELISA. Repeated ANOVA, ANOVA tests, and Kolmogorov–Smirnov normality tests on the SPSS program were used to statistically analyze the results. Result In the dose groups of 10,000 IU and 5000 IU, significant increases in the levels of vitamin D, TLR-2, and TLR-4 were observed at weeks 4 and 8 (p 50 ng/dl to optimally act as an immunomodulator.
