Infections are common and can be fatal in patients undergoing long-term dialysis. Recent studies have shown conflicting evidence associating infection with vitamin D status or use of vitamin D and have not been systematically reviewed in this population.
So a group of medical scientists took a detailed look at existing studies and carefully analysed the results.
If a patient has high or normal serum levels of vitamin d and uses vitamin D supplements, there is a lower risk osf infection for patients on long-term dialysis.
A review by two groups, one at Karolinska Institutet in Stockholm, Sweden and the other at Guangdong Provincial Hospital of Chinese Medicine, of 17 studies came to this conclusion. Also, those with vitamin D deficiency who took supplements reduced their chances of infection by 41%.
