curcumin and Urinary-Tract-Infections

To assess whether the orally administered combination of hyaluronic acid (HA), chondroitin sulfate (CS), curcumin and quercetin could be effective in preventing recurrent cystitis in postmenopausal women and whether its efficacy was conditioned by the concurrent use of local estrogen therapy.. This was a prospective evaluation of 145 postmenopausal women consecutively recruited from the database of three different investigators. All women should have mild-to-moderate urogenital atrophy and a history of recurrent urinary tract infections (≥2 episodes within 6 months or ≥3 episodes within 12 months documented by positive urine cultures) during the last year. Patients were assigned to three different therapeutic regimens: the first group was treated only with vaginal estrogens, the second group only with HA, CS, curcumin and quercetin per os, and the third group was treated with HA, CS, curcumin and quercetin associated with local estrogens. We evaluated the number of patients with <2 infective episodes in the 6-month follow-up and <3 episodes in the 12-month follow-up (main aim definition) and the reduction of related symptoms through a Visual Analog Scale (VAS) and the Pelvic Pain and Urgency/Frequency (PUF) patient symptom scale. Student's t-test and chi-squared test were used for data analysis as appropriate.. At 6-month follow up, the main aim rate was 8%, 11.1% and 25% in the three groups, respectively (p<0.05 compared to baseline only in group 3). Although the reduction in the number of recurrent episodes became significant in all groups at 1 year follow-up, the main aim rate was almost double in women receiving both local estrogens and oral therapy (group 3) compared to those receiving single treatments. The improvement of related symptoms was significant in all groups at 12-month follow-up.. In postmenopausal women, the combination of HA, CS, curcumin and quercetin per os was effective in preventing recurrent urinary tract infections, especially if administered with vaginal estrogen therapy.

Urinary tract infection is caused primarily by the quorum sensing (QS)-dependent biofilm forming ability of uropathogens. In the present investigation, an anti-quorum sensing (anti-QS) agent curcumin from Curcuma longa (turmeric) was shown to inhibit the biofilm formation of uropathogens, such as Escherichia coli, Pseudomonas aeruginosa PAO1, Proteus mirabilis and Serratia marcescens, possibly by interfering with their QS systems. The antibiofilm potential of curcumin on uropathogens as well as its efficacy in disturbing the mature biofilms was examined under light microscope and confocal laser scanning microscope. The treatment with curcumin was also found to attenuate the QS-dependent factors, such as exopolysaccharide production, alginate production, swimming and swarming motility of uropathogens. Furthermore, it was documented that curcumin enhanced the susceptibility of a marker strain and uropathogens to conventional antibiotics.

Chandraprabha Vati (CV) is an Indian polyherbal Siddha drug, traditionally used as an anti-inflammatory agent for arthritis and urinary ailments. This study explores its effect on mice with urinary tract infection.. The in-organic constituents of CV were determined by atomic absorption spectroscopy and phytochemical analysis was carried out. The supplementing dose of CV to infected experimental mice was determined by in vitro antimicrobial assay. Transurethrally infected animals were supplemented with CV extract for 20 days after confirmation of UTI. The animals were euthanized as per the guidelines and the tissues were harvested from the control and infected mice for histopathological examination the antimicrobial peptide Tamm-Horsfall protein (THP) and inflammatory markers (tumor necrosis factor-α and nuclear factor kappa-light-chain-enhancer of activated B cells) to ascertain the modulatory effects of CV. Indicators for oxidative stress and protein levels were also quantified to validate the efficacy of CV.. Terpenoids and flavanoids were majorly found to constitute CV along with zinc and iron as in-organic content. Histological and immunohistochemical studies confirmed the pronounced infection in the kidney of the uropathogenic Escherichia coli-infected animals. Supplementation of CV significantly restored the increased levels of the antimicrobial proteins, THP, and inflammatory markers.. This study explored the efficacy of the aqueous extract of CV as an alternative medication for the synthetic analogues administered for UTI. This study also provides information on the possible role of THP as an antimicrobial protein in the kidney in preventing infection due to uropathogenic E coli.
