Vitamin D is effective for treating bladder infections and maintaining bladder health, according to a study by Intercept Pharmaceuticals. In the study, vitamin D receptors treated benign prostatic hyperplasia, a syndrome that causes prostate overgrowth, urinary imitative symptoms and inflammation. Vitamin D effectively targets the pathway in bladder cells to reduce inflammation, build cell walls, and protect against bacteria and infection. Intercept Pharmaceuticals

The urinary tract is frequently being exposed to potential pathogens and rapid defence mechanisms are therefore needed. Cathelicidin, a human antimicrobial peptide is expressed and secreted by bladder epithelial cells and protects the urinary tract from infection. Here we show that vitamin D can induce cathelicidin in the urinary bladder. We analyzed bladder tissue from postmenopausal women for expression of cathelicidin, before and after a three-month period of supplementation with 25-hydroxyvitamin D3 (25D3). Cell culture experiments were performed to elucidate the mechanisms for cathelicidin induction. We observed that, vitamin D per se did not up-regulate cathelicidin in serum or in bladder tissue of the women in this study. However, when the bladder biopsies were infected with uropathogenic E. coli (UPEC), a significant increase in cathelicidin expression was observed after 25D3 supplementation. This observation was confirmed in human bladder cell lines, even though here, cathelicidin induction occurred irrespectively of infection. Vitamin D treated bladder cells exerted an increased antibacterial effect against UPEC and colocalization to cathelicidin indicated the relevance of this peptide.
In the light of the rapidly growing problem of resistance to common urinary tract antibiotics, we suggest that vitamin D may be a potential complement in the prevention of UTI.

“Vitamin D, it turns out, is necessary for the production of anti-microbial peptides, substances that fight off infection-causing bacteria, fungi, and viruses when these pathogens try to move into organs and through mucous membranes.”

''In the light of the rapidly growing problem of resistance to common urinary tract antibiotics, we suggest that vitamin D may be a potential complement in the prevention of UTI.
Determining the vitamin D status of individuals with a history of UTI may be of importance to evaluate their ability to fend off intruding bacteria.''
