Analysis of Urinary, Vaginal and Intestinal Microbiota in Patients With Neurogenic Bladder

Study Overview
=================
Brief Summary
-----------------
The neurogenic bladder and bowel are two pathological conditions occurring when damaged innervation results in functional alteration of both the bladder and the bowel with a clinical presentation that can vary from retention to incontinence often associated with an increased risk of infection. Specific microbiological patterns of urinary microbiota are associated with states of well-being of the host and play protective and preventive functions for numerous urological pathologies such as urinary tract infections, urinary incontinence and bladder tumors. What the healthy profile of the bladder microbiota is in subjects with neurogenic bladder appears currently poorly reported in literature data. Indeed, in these populations different strains of uropathogenic microorganisms, such as E.Coli, Klebsiella, Pseudomonas and Enterococcus, are dominant compared to healthy subjects where Lactobacillus predominates. The characterization of the gut microbiota in terms of composition can be a key tool for understanding the effects that preventive therapeutic and nutritional approaches or clinical procedures have on it, subsequently offering the possibility of improving and complementing these treatments. Among human microbiota, the vaginal one, the vaginoma, is among the most studied for its correlation with female health status. The core of the vaginal microbiome is Lactobacillus which under physiological conditions is represented in particular by Lactobacillus Crispatus, Lactobacillus Iners, Lactobacillus Jensenii and Lactobacillus Gasseri. Immune cells and related PRRs receptors interact with the microorganisms in the vaginal environment of the vaginal environment are the immune cells and the related PRRs receptors thus the close relationship between microbiome and immunity as well as between vaginoma and genitourinary well-being is now evident. The characterization of the gut, urinary and vaginal microbiota in patients with neurogenic bladder secondary to spina bifida and multiple sclerosis can help identify a health promoting profile to personalize and characterize the therapeutic approach.
