The relevance of vitamin D for infections after kidney transplantation is poorly defined. 25‐OH vitamin D (25‐OHD) levels of 135 kidney transplant recipients, enrolled in the Swiss Transplant Cohort Study, were determined peri‐transplant and 6 months post‐transplant. Logistic regression was used to address the associations of 25‐OHD and overall infections and bacterial infections, respectively. For the first 6 months post‐transplant, 25‐OHD peri‐transplant, and for the second period (after 6 to 30 months post‐transplant), 25‐OHD at 6 months post‐transplant was considered. Vitamin D deficiency was common peri‐transplant and remained highly prevalent 6 months after transplantation despite frequent supplementation. Median 25‐OHD levels increased from 12.0 ng/mL (IQR 5.3‐19.5) peri‐transplant to 16.5 ng/mL (IQR 10.6‐22.6) 6 months post‐transplant ( P = .005). We did not detect a significant association between 25‐OHD and overall infections (adjusted odds ratio (aOR) 1.05, 95% confidence interval (95%CI) 0.44‐2.51; aOR 0.67, 95%CI 0.31‐1.43) or bacterial infections (aOR 0.79, 95%CI 0.32‐1.96; aOR 0.79, 95%CI 0.35‐1.75) for the first and second period. To conclude, at both time points, vitamin D deficiency was observed in more than 50% of kidney recipients, albeit an increase in 25‐OHD in the longitudinal course was observed. No significant association between 25‐OHD and infections was detected.
