The aim of this preliminary study was to test whether the use of a new dietary supplement (UROIAL TM sachets) containing cranberry extracts (S&R PACs), D-mannose, hyaluronic Acid and Glucosamine Chondroitin may reduce the incidence of episodes of cystitis and improve urinary symptoms. METHODS: In this prospective comparative study, 40 women with an acute diagnosis of cystitis received a single sachet of Fosfomycin Tromethamine (3gr). The subjects were then randomly assigned to two groups: Group A: 20 women were given UROIAL TM , 2 sachet per day during the first 7 days, then 1 sachet per day for two weeks; Group B: 20 women did not receive any treatment to serve as a control group. RESULTS: The results of the present study showed a complete remission of urinary symptoms in 37 women, a slight decrease in urinary symptoms was observed in 2 subjects, whereas 1 woman who stopped the treatment was considered a drop-out. Patients in Group A had a lower incidence of episodes of recurrent cystitis during treatment and follow-up; urine samples had significantly lower median bacterial load compared to baseline as well as a symptomatic relief was reported in treated subjects despite the control group. DISCUSSION: Several studies have investigated and demonstrated the role of cranberry extracts in the prevention of recurrent urinary tract infections (UTIs), on different selected subpopulations and even at increased risk of UTI. Even the use of D-mannose, a natural sugar has proven to have clinical benefit, although clinical data is limited. A randomized placebo-controlled non-blinded clinical trial has shown that a daily dose of 2 g d-mannose was superior to placebo in preventing UTI. Mannose receptors are found on uroepithelial cells lining the urinary tract they constitute the protective mucopolysaccharide layer of the bladder. The mechanism of action involves binding of the mannose receptors to E. coli pili, thus preventing both adhesion to and invasion of urothelial cells. The interaction between mannose molecules and E. coli bacteria can then be washed away with urine voiding. CONCLUSIONS: Our data indicate that the addition of GAGs (hyaluronic acid and chondroitin sulfate) to cranberry/D-Mannose containing products could represent a valid novel therapeutic approach for the treatment and/or prophylaxis of cystitis.","PeriodicalId":72911,"journal":{"name":"Endocrinology, diabetes and metabolism journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49365338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We did a randomised trial to assess the efficacy and safety of a popular Ayush product, Sugar Balance ® (sugar balance) in patients with newly diagnosed type 2 diabetes and prediabetes. Methods: In this multicentre, double blind placebo-controlled trial, we randomly assigned (1: 1) eligible participants, 30 years of age or older, of either gender and diagnosed with type 2 diabetes (HbA1c ≥ 6.5%) or prediabetes (FPG ≥ 5.6 mmol/L). We used computer-generated ramdomisation, stratified by type of diagnosis (prediabetes or diabetes). Active recipients were to receive 250 mg capsules containing 3 Organic certified whole herbs : Coccinia indica, Bougainvillea spectabilis and Madagascar periwinkle (sadabahar). The recommended dose was 2 capsules twice daily. The primary outcome was ≥0.5% reduction in HbA 1c for type 2 diabetes subjects and an increased incidence of normalization in impaired fasting blood glucose for prediabetes subjects at 6 months after randomization. The primary analysis included all subjects who received the allocated intervention and had 1 follow up visit after randomisation. All subjects received standard life style recommendations for diet and exercise. Type 2 diabetes subjects were allowed to be on biguanides (metformin) of their choice. This trial is registered with ClinicalTrials.gov, number NCT02866539 and clinical trials registry of India, number CTRI/2016/11/007435, and is completed. Findings: Between December 14 th 2016 and 28 th August 2017, 122 subjects were randomly assigned to active sugar balance (n=61) or matching placebo (n=61), of whom one subject (assigned to placebo) did not receive the allocated intervention. All follow up was completed on 16 th December 2017. At 6 months type 2 diabetes subjects allocated to active arm had a mean reduction of HbA 1c of -0.52% versus -0.43% among placebo arm (difference of -0.09% 95% CI -0.1705 - -0.0095). 13 (52%) versus 4 (15.4%) prediabetes subjects receiving the polyherbal achieved normalization of impaired fasting glycaemia (<100 mg/dl) (difference of 36.6% 95% CI 10.683 - 56.805). None of the study participants experienced significant hypoglycemia or significant changes in their safety clinical biochemistry parameters on therapy. Conclusions: Sugar Balance promises to be effective and safe supplement for type 2 diabetes subjects to achieve a better optimization of HbA 1c when taken along with standard dose of metformin and for prediabetes subjects to achieve their target fasting blood sugars with diet and exercise.","PeriodicalId":72911,"journal":{"name":"Endocrinology, diabetes and metabolism journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46265570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since a number of scientific reports are present on the beneficial effects of raw ginger in Type 2 diabetes mellitus, it was of interest to determine the anti-hyperglycemic efficacy of cooked (boiled) ginger through oral glucose tolerance test (OGTT) in mice. The OGTT results showed that when administered at doses of 50, 100, 200 and 400 mg per kg body weight, methanolic extract of cooked ginger (MEZOC) reduced blood glucose in glucose-loaded mice by 8.0, 20.3, 29.2, and 32.0%, respectively. By comparison, a standard antihyperglycemic drug, glibenclamide, when administered at a dose of 10 mg per kg, reduced blood glucose levels by 48.8%.

Since cooking causes ginger to be less pungent, partaking of ginger in such a manner may prove to be more acceptable to diabetic patients and help control their blood glucose concentrations.","PeriodicalId":72911,"journal":{"name":"Endocrinology, diabetes and metabolism journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44785631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
