Abstract
Patients with type 2 diabetes and/or obesity and established cardiovascular disease are at increased risk for recurrent cardiovascular events. The indications of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors have been expanded in the last decade due to benefit in cardiovascular outcome trials and are now considered guideline-recommended therapy for patients with type 2 diabetes and cardiovascular disease. Emerging data have begun to suggest that GLP-1RAs can decrease major adverse cardiovascular events among patients with obesity without diabetes. Overall, prescription of these agents remains low, despite being key to improve disparities in recurrent cardiovascular events. In this review, we discuss optimal medical therapy for secondary prevention for stable ischemic heart disease.

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2is) improve clinical outcomes in persons with heart failure (HF). This class of agents has been consistently associated with an increased risk of mycotic genital infections (MGIs), and in some, but not all, trials, urinary tract infections (UTIs). Other medications widely used for cardiac conditions do not cause MGIs and UTIs, so cardiologists and their supporting teams will be encountering clinical questions that they previously did not have to address. This review provides clinicians with practical recommendations about SGLT2i use in individuals with HF as related to the associated MGI and possible UTI risks. Overall, given the benefit of SGLT2is in clinical outcomes, the threshold for not initiating or discontinuing SGLT2is due to concerns for MGIs or UTIs should be high for persons with HF. Likewise, when SGLT2is are discontinued for such concerns, the threshold for reinitiation should be low.

Abstract
Fungal infections can cause severe disease and death and impose a substantial economic burden on healthcare systems. Public health research requires a multidisciplinary approach and is essential to help save lives and prevent disability from fungal diseases. In this manuscript, we outline the main public health research priorities for fungal diseases, including the measurement of the fungal disease burden and distribution and the need for improved diagnostics, therapeutics, and vaccines. Characterizing the public health, economic, health system, and individual burden caused by fungal diseases can provide critical insights to promote better prevention and treatment. The development and validation of fungal diagnostic tests that are rapid, accurate, and cost-effective can improve testing practices. Understanding best practices for antifungal prophylaxis can optimize prevention in at-risk populations, while research on antifungal resistance can improve patient outcomes. Investment in vaccines may eliminate certain fungal diseases or lower incidence and mortality. Public health research priorities and approaches may vary by fungal pathogen.

Glycogen Metabolism in Candida albicans Impacts Fitness and Virulence during Vulvovaginal and Invasive Candidiasis. mBio 2023; 14:e0004623. [PMID: 36840583 PMCID: PMC10127583 DOI: 10.1128/mbio.00046-23] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 02/01/2023] [Indexed: 02/24/2023] Open
Abstract
The polymorphic fungus Candida albicans remains a leading cause of both invasive and superficial mycoses, including vulvovaginal candidiasis (VVC). Metabolic plasticity, including carbohydrate catabolism, confers fitness advantages at anatomical site-specific host niches. C. albicans possesses the capacity to accumulate and store carbohydrates as glycogen and can consume intracellular glycogen stores when nutrients become limited. In the vaginal environment, estrogen promotes epithelial glycogen accumulation and C. albicans colonization. However, whether these factors are mechanistically linked is unexplored. Here, we characterized the glycogen metabolism pathways in C. albicans and investigated whether these impact the long-term survival of C. albicans, both in vitro and in vivo during murine VVC, or virulence during systemic infection. SC5314 and 6 clinical isolates demonstrated impaired growth when glycogen was used as the sole carbon source, suggesting that environmental glycogen acquisition is limited. The genetic deletion and complementation of key genes involved in glycogen metabolism in Saccharomyces cerevisiae confirmed that GSY1 and GLC3, as well as GPH1 and GDB1, are essential for glycogen synthesis and catabolism in C. albicans, respectively. Potential compensatory roles for a glucoamylase encoded by SGA1 were also explored. Competitive survival assays revealed that gsy1Δ/Δ, gph1Δ/Δ, and gph1Δ/Δ sga1Δ/Δ mutants exhibited long-term survival defects in vitro under starvation conditions and in vivo during vaginal colonization. A complete inability to catabolize glycogen (gph1Δ/Δ sga1Δ/Δ) also rendered C. albicans significantly less virulent during disseminated infections. This is the first study fully validating the glycogen metabolism pathways in C. albicans, and the results further suggest that intracellular glycogen catabolism positively impacts the long-term fitness of C. albicans in nutrient deficient environments and is important for full virulence. IMPORTANCE Glycogen is a highly branched polymer of glucose and is used across the tree of life as an efficient and compact form of energy storage. Whereas glycogen metabolism pathways have been studied in model yeasts, they have not been extensively explored in pathogenic fungi. Using a combination of microbiologic, molecular genetic, and biochemical approaches, we reveal orthologous functions of glycogen metabolism genes in the fungal pathogen Candida albicans. We also provide evidence that extracellular glycogen poorly supports growth across the Candida species and clinical isolates. Competitive fitness assays reveal that the loss of glycogen synthesis or catabolism significantly impacts survival during both in vitro starvation and the colonization of the mouse vagina. Moreover, a global glycogen catabolism mutant is rendered less virulent during murine invasive candidiasis. Therefore, this work demonstrates that glycogen metabolism in C. albicans contributes to survival and virulence in the mammalian host and may be a novel antifungal target.

Abstract
The prevalence of type 2 diabetes mellitus continues to increase in many Asian countries, with possible contributing factors, such as younger-onset disease, diabetes development at lower body mass index, higher visceral fat accumulation and poorer β-cell function, among Asian populations. Sodium-glucose cotransporter 2 inhibitors have been shown to confer favorable effects in type 2 diabetes mellitus patients, such as improved glycemic control, weight and blood pressure reduction, and importantly, cardiorenal benefits. Sodium-glucose cotransporter 2 inhibitors are generally well-tolerated, and have a well-defined safety profile based on evidence from numerous clinical trials and post-marketing pharmacovigilance reporting. To our knowledge, this review is the first to provide a comprehensive coverage of the adverse events of sodium-glucose cotransporter 2 inhibitors, as well as their management and counseling aspects for Asian type 2 diabetes mellitus populations.

Abstract
INTRODUCTION Sodium-glucose co-transporter 2 (SGLT2) inhibitors, or gliflozins, are used as mono or combined therapy in the management of diabetes. Genital infections are the most common reported adverse effect, as a result of induced glycosuria. Cutaneous features of patients experiencing vulval symptoms while on SGLT2 inhibitor therapy have not been clearly described in published literature. We have observed a specific inflammatory vulvitis with psoriasiform features in patients taking SGLT2 inhibitors, related to candidiasis in most cases. METHODS AND RESULTS Demographic and treatment outcomes of 11 patients with characteristic inflammatory changes after starting SGLT2 inhibitors were extracted from electronic records. Ninety-one percent (n = 10) had candidiasis, treated with fluconazole. Six (54.5%) were able to continue SGLT-2 inhibitors through the addition of topical treatments, but five patients had to discontinue the drug. CONCLUSIONS SGLT2 inhibitors can result in characteristic inflammatory vulvitis. Treatment with topical agents and single-dose antifungals may allow patients to continue their therapy to achieve improved glycemic control. In resistant cases, discontinuation of the drug is necessary. We highlight this effect so that early treatment can be initiated to alleviate symptoms and recognition of underlying cause.

Abstract
The skin is the largest and outermost organ of the human body. The microbial diversity of the skin can be influenced by several variable factors such as physiological state, lifestyle, and geographical locations. Recent years have seen increased interest in research aiming at an improved understanding of the relationship between the human microbiota and several diseases. Albeit understudied, interesting correlations between the skin microbiota and several dermatological conditions have been observed. Studies have shown that a decrease or increase in the abundance of certain microbial communities can be implicated in several dermatological pathologies. This narrative review (i) examines the role of the skin microbiota in the maintenance of skin homeostasis and health, (ii) provides examples on how some common skin diseases (acne inversa, candidiasis, psoriasis) are associated with the dysbiosis of microbial communities, and (iii) describes how recent research approaches used in skin microbiome studies may lead to improved, more sensitive diagnostics and individual therapeutics in the foreseeable future.

Abstract
Diabetes mellitus is a chronic metabolic disease characterized by hyperglycemia and glucosuria, and is a risk factor for Candida infections. To reveal the potential effects of glucosuria on Candida spp., we investigated their growth and antifungal susceptibilities in normal human urine to which glucose was added. The viable cell numbers of Candida spp. were more than 10 fold higher in the urine added 3000 mg/dL glucose than in plain urine. In antifungal susceptibility, more than 80% of Candida albicans clinical isolates increased minimum inhibitory concentrations of azoles and 5-fluorocytosine with the addition of glucose, and exceeded their breakpoints. In most of the C. albicans clinical isolates, the mRNA expression of the azole resistance genes ERG11, CDR1, CDR2, and MDR1 in the presence of glucose in urine. These observations provide valuable information about the clinical course and therapeutic effects of azoles against C. albicans infections in patients with diabetes mellitus and hyperglucosuria.

Abstract
INTRODUCTION Sodium-glucose co-transporter-2 (SGLT2) inhibitors moderately reduce glucose levels in type-2 diabetes mellitus (T2DM). Some cases of diabetic ketoacidosis (DKA) were reported with SGLT2 inhibitors. However, data on the long-term safety of dapagliflozin in Saudi Arabia are lacking. The present study aimed to monitor the safety of dapagliflozin in patients with T2DM and evaluate the change in HbA1c during the observation period compared to baseline. METHODS This was a local, prospective, single-arm, non-interventional, regulatory post-marketing study. The study was conducted in Saudi Arabia from May 2017 to September 2019. Patients received either 5 or 10 mg dapagliflozin in conjunction with diet and exercise modifications to treat T2DM. The occurrence of adverse events was observed over the treatment duration and for 3 days after administering the last dose of dapagliflozin. RESULTS A total of 527 patients were recruited in the study, 524 of which were eligible for the statistical analysis. About 62% were males. The median (IQR) age was 52.3 (14.8) years, while the median (IQR) body mass index was 31.6 (7.7) kg/m2. The median (IQR) duration since the patients were first diagnosed with T2DM was 8.78 (6.73) years. The most common comorbidities were hyperlipidemia (51.1%) and hypertension (41.1%). Almost three-quarters of the study population (73.7%) received other antidiabetic medications in addition to dapagliflozin. Over a period of 12 months, a total of 106 adverse events were experienced by 65 (12.33%) patients. Vulvovaginal pruritus (3.1%), dysuria (2.7%), polyuria (1.3%), urinary tract infections (1%), fatigue (0.8%), and hypoglycemia (0.8%) were among the reported adverse events. One case of DKA (0.2%) was reported. The mean (SD) HbA1c% level significantly decreased from 8.6 (1.6) % at baseline to reach 7.2 (1.2) % after 12 months of treatment (p < 0.0001). CONCLUSION Dapagliflozin was found to be a well tolerated and effective treatment option for T2DM patients in Saudi Arabia. Vulvovaginal pruritus and dysuria were the most common adverse events.

[PMID: 34274073 DOI: 10.1016/j.maturitas.2021.06.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 05/31/2021] [Accepted: 06/08/2021] [Indexed: 11/28/2022]
Abstract
This study aimed to investigate the age- and sex-specific risk of urogenital infections in patients with type 2 diabetes mellitus (T2DM) treated with sodium-glucose co-transporter 2 (SGLT2) inhibitors. A self-controlled case series was conducted using annual national patient sample datasets from 2016 and 2017. Patients who were treated with SGLT2 inhibitors and who received antimicrobials for urogenital infections were included in the study. The incidence rate ratio (IRR) of urogenital infections during SGLT2 inhibitor exposure were compared with those in the non-exposure period. A total of 2,949 patients were included in the analysis, and 71.2% of the patients were women aged ≥ 50 years. Stratified analysis by age and sex showed that only women ≥ 50 years showed a significant increase in the risk of urinary tract infections (UTIs) (IRR 1.25, 95% CI 1.14-1.37) and genital infections (IRR 1.44, 95% CI 1.28-1.62). The highest risk of UTI risk was observed 8-14 days after initiating SGLT2 inhibitor therapy (IRR 1.49, 95% CI 1.07-2.08), and after 15-28 days for genital infections (IRR 2.11, 95% CI 1.66-2.67) in women ≥ 50. SGLT2 inhibitors increase the risk of urogenital infections in T2DM patients, especially in women aged ≥ 50 years. Monitoring of urogenital infections in women aged ≥ 50 years, especially during the first month after starting SGLT2 inhibitors, is recommended.

Sodium-Glucose Co-Transporter 2 Inhibitors (SGLT2i) Exposure and Outcomes in Type 2 Diabetes: A Systematic Review of Population-Based Observational Studies. Diabetes Ther 2021; 12:991-1028. [PMID: 33665777 PMCID: PMC7994468 DOI: 10.1007/s13300-021-01004-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 01/13/2021] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION Sodium-glucose co-transporter 2 inhibitors (SGLT2is) are licensed for the treatment of type 2 diabetes (T2D) and more recently for heart failure with or without diabetes. They have been shown to be safe (from the cardiovascular (CV) perspective) and effective (in terms of glycaemia, and in some cases, in reducing CV events) in extensive randomised controlled trials (RCTs). However, there remain concerns regarding the generalisability of these findings (to those ineligible for RCT participation) and about non-CV safety. For effectiveness, population-based pharmacoepidemiology studies can confirm and extend the findings of RCTs to broader populations and explore safety, for which RCTs are not usually powered, in more detail. METHODS A pre-planned and registered ((International PROSPEctive Register Of Systematic Reviews) PROSPERO registration CRD42019160792) systematic review of population-based studies investigating SGLT2i effectiveness and safety, following Meta-analyses Of Observational Studies in Epidemiology (MOOSE) guidelines was conducted. RESULTS A total of 37 studies were identified (total n = 1,300,184 adults; total follow-up 910,577 person-years; exposures: SGLT2i class, canagliflozin, dapagliflozin and empagliflozin) exploring CV disease (CVD) outcomes, acute kidney injury (AKI), lower limb amputation (LLA), diabetic ketoacidosis (DKA), bone fracture, urinary tract infection (UTI), genital mycotic infection (GMI), hypoglycaemia, pancreatitis and venous thromboembolism. For CV and mortality outcomes, studies confirmed the associated safety of these drugs and correlated closely with the findings from RCTs, which may extend to primary CVD prevention (major adverse cardiovascular events point estimate range (PER) hazard ratio (HR) 0.78-0.94; hospitalised heart failure PER HR 0.48-0.79). For safety outcomes, SGLT2i exposure was not associated with an increased risk of AKI (PER HR 0.40-0.96), fractures (PER HR 0.87-1.11), hypoglycaemia (PER HR 0.76-2.49) or UTI (PER HR 0.72-0.98). There was a signal for increased association for GMIs (PER HR 2.08-3.15), and possibly for LLA (PER HR 0.74-2.79) and DKA (PER HR 0.96-2.14), but with considerable uncertainty. CONCLUSION In T2D, SGLT2is appear safe from the CV perspective and may have associated benefit in primary as well as secondary CVD prevention. For safety, they may be associated with an increased risk of GMI, LLA and DKA, although longer follow-up studies are needed.

Abstract
Background Sodium-glucose co-transporter 2 (SGLT2) inhibitors are novel hypoglycemic agents which reduce reabsorption of glucose at the renal proximal tubule, resulting in significant glycosuria and increased risk of genital mycotic infections (GMI). These infections are typically not severe as reported in large systematic reviews and meta-analyses of the medications. These reviews have also demonstrated significant cardiovascular benefits through other mechanisms of action, making them attractive options for the management of Type 2 diabetes mellitus (T2DM). We present two cases with underlying abnormalities of the urogenital tract in which the GMI were complicated and necessitated cessation of the SGLT2 inhibitor. Case presentations Both cases are patients with T2DM on empagliflozin, an SGLT2 inhibitor. The first case is a 64 year old man with Candida albicans balanitis and candidemia who was found to have an obstructing renal calculus and prostatic abscess requiring operative management. The second case describes a 72 year old man with Candida glabrata candidemia who was found to have prostatomegaly, balanitis xerotica obliterans with significant urethral stricture and bladder diverticulae. His treatment was more complex due to fluconazole resistance and concerns about urinary tract penetration of other antifungals. Both patients recovered following prolonged courses of antifungal therapy and in both cases the SGLT2 inhibitor was ceased. Conclusions Despite their cardiovascular benefits, SGLT2 inhibitors can be associated with complicated fungal infections including candidemia and patients with anatomical abnormalities of the urogenital tract may be more susceptible to these infections as demonstrated in these cases. Clinicians should be aware of their mechanism of action and associated risk of infection and prior to prescription, assessment of urogenital anatomical abnormalities should be performed to identify patients who may be at risk of complicated infection.

Abstract
BACKGROUND Sodium-glucose-cotransporter-2 (SGLT2) inhibitors have proven to be effective in improving glycemic control and lowering body weight in patients with type 2 diabetes mellitus. However, the efficacy and safety on weight loss in adults with overweight or obesity but not diabetes remain unclear. In this article, we aimed to identify the efficacy and safety of SGLT2 inhibitors in adults with overweight or obesity but not diabetes in randomized controlled studies (RCTs). METHODS We searched for RCTs concerning SGLT2 inhibitors in adults with overweight or obesity but not diabetes in Medline (Ovid SP), Embase (Ovid SP), Cochrane Central Register of Controlled Trials (Ovid SP), and ClinicalTrials.gov up to February 2021. The primary outcomes were changes in body weight and body mass index (BMI). Trial sequential analysis (TSA) was used to test the reliability of the primary outcomes. We analyzed the data using Review Manager 5.3 and pooled data to calculate the mean differences (MDs) or the relative risk (RR). We assessed the evidence quality of evidence of outcomes according to GRADE. RESULTS Six randomized controlled trials involving 872 individuals were included in the meta-analysis. Compared to the placebo group, the SGLT2 inhibitors group had statistically significant reductions in absolute changes in body weight (MD: -1.42 kg, 95% CI: -1.70 to -1.14; P<0.00001) and BMI (MD: -0.47 kg/m2, 95% CI: -0.63 to -0.31; P<0.00001) in SGLT2 inhibitors group, as indicated by TSA. However, no significant benefits were observed in the SGLT2 inhibitors group in terms of waist circumference (MD: -1.34 cm, 95%CI: -2.75 to 0.07; Z=1.86, P=0.06) compared with the placebo group. The GRADE profiles indicated very low-quality evidence for body weight change and low-quality evidence for BMI change. SGLT2 inhibitors were generally safe and well tolerated. CONCLUSION SGLT2 inhibitors could be used in selected adults with overweight and obesity but not diabetes if they are at low risk of genital infection and urinary infection. Further studies are warranted to confirm the efficacy and safety of SGLT2 inhibitors in adults with overweight or obesity but not diabetes for long-term weight management.

Abstract
The incidence of diabetes mellitus has increased in Saudi Arabia, which has raised the risk of vulvovaginal candidiasis (VVC). This study highlights the prevalence and antifungal susceptibility of Candida species among postmenopausal women with diabetes with symptoms of VVC in Taif, a city in Saudi Arabia. Several diagnostic tools were used to differentiate the yeast isolates, including microscopic examination, culture morphology on CHROM agar, further confirmation with the VITEK 2 system, and ITS1 and ITS4 region sequencing. Antifungal susceptibility of the selected Candida species was determined using the VITEK 2 system (bioMérieux Inc., USA). Out of the 550 high vaginal swabs investigated, 86 specimens were Candida species positive (15.6%) with a significant difference according to age; the positivity in the 45–50 years' age group (12%) was higher than that in the 51–55 years' age group (3.6%). Candida albicans was the most common causative agent in 51 samples (59.3%), followed by C. glabrata in 21 samples (24.41%) and C. krusei in 14 samples (16.27%), with no significant differences between the age groups. Three isolates, including two C. albicans and one C. krusei, exhibited resistance against all the tested antifungal agents. CHROM agar and VITEK 2 were accurate phenotypic tools to identify Candida species with 100% sensitivity and specificity and were consistent with the phylogenetic characterization. The data emphasized the importance of identifying Candida species and their antifungal susceptibility among postmenopausal women with diabetes, highlighting the potential risk posed by diabetes in this age group.

Abstract
Sodium-glucose co-transporter 2 (SGLT2) inhibitors exhibit impressive cardio-renal benefits in patients with a high cardiovascular risk. Genital yeast infections are important side effects of this class of drugs. We report a case of Candida glabrata sepsis secondary to a Candida infection of the urostomy of a patient on SGLT2 inhibitor therapy. In urostomy patients, one should critically evaluate the risk of mycotic infections against the cardiovascular and glycaemic benefits of SGLT2 inhibition. Urostomy patients without a high cardiovascular risk should not be treated with SGLT2 inhibitors.

Abstract
OBJECTIVE The aim of this study was to explore the dose response of licogliflozin, a dual inhibitor of sodium/glucose cotransporter 1 (SGLT1) and 2 (SGLT2), by evaluating change in body weight in adults with overweight or obesity. METHODS This dose-response analysis evaluated change in body weight following 24 weeks with four once-daily and twice-daily licogliflozin doses (2.5-150 mg) versus placebo (primary end point). A further 24-week analysis evaluated the efficacy and safety of two once-daily licogliflozin doses in maintaining initial weight reduction. RESULTS Licogliflozin once daily or twice daily produced a significant dose-response signal for weight loss versus placebo (P < 0.0001). However, mean adjusted percent changes in body weight after 24 weeks were modest, ranging from -0.45% to -3.83% (in the 50 mg twice daily group [95% CI: -5.26% to -2.48%]; n = 75). Responder analysis of ≥ 5% weight loss at week 24 revealed significant differences versus placebo, which were most pronounced with highest doses of 50 mg twice daily (45.3%) and 150 mg once daily (42.9%) (both P < 0.01). While weight loss was greater at higher doses, gastrointestinal adverse events were also more frequent. The 50-mg once-daily dose had perhaps the best balance between efficacy and tolerability. CONCLUSIONS Licogliflozin produced significant reductions in body weight versus placebo. However, the magnitude of weight reduction was modest.

Abstract
AIM To assess the efficacy and safety of empagliflozin as add-on to insulin in Japanese patients with type 2 diabetes (T2D). MATERIALS AND METHODS This multicentre, double-blind, parallel-group study randomized Japanese patients with T2D insufficiently controlled with insulin (1:1:1) to empagliflozin 10 mg (n=89), empagliflozin 25 mg (n=90) or placebo (n=90) for 52 weeks. The primary endpoint was change from baseline in glycated haemoglobin (HbA1c) at 16 weeks. RESULTS At 16 weeks, empagliflozin 10 mg and 25 mg significantly decreased HbA1c: adjusted mean difference -0.92% (95% confidence interval [CI] -1.11, -0.73) and -1.00% (95% CI -1.18, -0.82; both P<0.0001) compared with placebo. This difference was maintained up to 52 weeks: adjusted mean difference at 52 weeks -0.90% (95% CI -1.09, -0.70) and -0.96% (95% CI -1.15, -0.77; both P<0.0001). At 52 weeks, significant improvements in fasting plasma glucose (adjusted mean difference -27.62 mg/dL [95% CI -36.15, -19.08] and -31.99 mg/dL [95% CI -40.35, -23.62]) and in body weight (-1.78 kg [95% CI -2.46, -1.10] and -1.92 kg [95% CI -2.58, -1.25]) were also seen with empagliflozin 10 mg and 25 mg compared with placebo (all P<0.0001). At 52 weeks, the frequency of adverse events (AEs) and serious AEs was similar in the three treatment groups; confirmed hypoglycaemia was reported slightly more in participants in the empagliflozin 10 mg and 25 mg groups (23.3% and 22.2% vs 14.4%). All hypoglycaemic events were mild in severity; no episodes required assistance. CONCLUSIONS In Japanese patients with insufficiently controlled T2D, adding empagliflozin 10 mg or 25 mg to insulin treatment was associated with clinically meaningful reductions in HbA1c at 16 weeks and was generally well tolerated.

Abstract
Candida albicans, along with other closely related Candida species, are the primary causative agents of vulvovaginal candidiasis (VVC)-a multifactorial infectious disease of the lower female reproductive tract resulting in pathologic inflammation. Unlike other forms of candidiasis, VVC is a disease of immunocompetent and otherwise healthy women, most predominant during their child-bearing years. While VVC is non-lethal, its high global incidence and profound negative impact on quality-of-life necessitates further understanding of the host and fungal factors that drive disease pathogenesis. In this review, we cover the current state of our understanding of the epidemiology, host response, fungal pathogenicity mechanisms, impact of the microbiome, and novel approaches to treatment of this most prevalent human candidal infection. We also offer insight into the latest advancements in the VVC field and identify important questions that still remain.

Abstract
Fungal infections are a major cause of skin and mucosal membrane disease. Immunocompromised individuals, such as those undergoing chemotherapy, are most susceptible to fungal infections. With a growing population of immunocompromised patients, there are many reports of increasing numbers of infections and of fungal strains resistant to current antifungals. One way to treat drug-resistant infections is to administer combinations of drugs to patients. Azoles are the most prescribed antifungals, as they are broad-spectrum and orally bioavailable. Terfenadine (TERF) and ebastine (EBA) are second-generation antihistamines, with EBA being used in many countries. In this study, we explored combinations of seven azole antifungals and two antihistamines (TERF and EBA) against a panel of 13 Candida fungal strains. We found 55 out of 91 combinations tested of TERF and EBA against the various fungal strains to be synergistic with the azoles. To evaluate the efficiency of these combinations to inhibit fungal growth, we performed time-kill assays. We also investigated the ability of these combinations to disrupt biofilm formation. Finally, we tested the specificity of the combinations towards fungal cells by mammalian cytotoxicity assays. These findings suggest a potential new strategy for targeting drug-resistant Candida infections.

Abstract
Objective: Vaginal Candida colonization is very common during pregnancy. An association between Candida colonization and obstetrical tears has not yet been investigated. We investigated whether vaginal Candida colonization during pregnancy is associated with an increased risk for obstetrical tears.Study design: A prospective cohort study was undertaken between the years 2014-2016, comparing pregnancy and delivery characteristics of women with and without Candida colonization during pregnancy. Clinical characteristics of Candida positive women and those with normal vaginal flora were collected. To test the statistical significance of the categorical variables, the chi-square test or Fisher's exact test were used, where appropriate. For continuous variables, the Student's t-test was used.Results: During the study period, 102 women with vaginal Candida during pregnancy (of whom 70% had Candida albicans species) and 102 controls with normal vaginal flora were included in the analysis. No significant differences were observed between Candida positive women and those with normal vaginal flora. Pregnancy and delivery outcomes were comparable and no increased risk of obstetrical tears was found in the Candida group.Conclusions: Vaginal colonization with Candida species during pregnancy was not found to be associated with an increased risk of obstetrical tears.

Abstract
Diabetic nephropathy (DN) is one of the most perilous side effects of diabetes mellitus type 1 and type 2 (T1DM and T2DM).). It is known that sodium/glucose cotransporter 2 inhibitors (SGLT 2i) and glucagone like peptide-1 receptor agonists (GLP-1 RAs) have renoprotective effects, but the molecular mechanisms are still unknown. In clinical trials GLP-1 analogs exerted important impact on renal composite outcomes, primarily on macroalbuminuria, possibly through suppression of inflammation-related pathways, however enhancement of natriuresis and diuresis is also one of possible mechanisms of nephroprotection. Dapagliflozin, canagliflozin, and empagliflozin are SGLT2i drugs, useful in reducing hyperglycemia and in their potential renoprotective mechanisms, which include blood pressure control, body weight loss, intraglomerular pressure reduction, and a decrease in urinary proximal tubular injury biomarkers. In this review we have discussed the potential synergistic and/or additive effects of GLP 1 RA and SGLT2 inhibitors on the primary onset and progression of kidney disease, and the potential implications on current guidelines of diabetes type 2 management.

Abstract
Chronic hyperglycaemia is a peculiar feature of diabetes mellitus (DM). Sequential metabolic abnormalities accompanying glucotoxicity are some of its implications. Glucotoxicity most likely corresponds to the vascular intricacy and metabolic alterations, such as increased oxidation of free fatty acids and reduced glucose oxidation. More than half of those with diabetes also develop cardiac abnormalities due to unknown causes, posing a major threat to the currently available marketed preparations which are being used for treating these cardiac complications. Even though impairment in cardiac functioning is the principal cause of death in individuals with type 2 diabetes (T2D), reducing plasma glucose levels has little effect on cardiovascular disease (CVD) risk. In vitro and in vivo studies have demonstrated that inhibitors of sodium glucose transporter (SGLT) represent a putative therapeutic intervention for these pathological conditions. Several clinical trials have reported the efficacy of SGLT inhibitors as a novel and potent antidiabetic agent which along with its antihyperglycaemic activity possesses the potential of effectively treating its associated cardiac abnormalities. Thus, hereby, the present review highlights the role of SGLT inhibitors as a successful drug candidate for correcting the shifts in deregulation of cardiac energy substrate metabolism together with its role in treating diabetes-related cardiac perturbations.

Abstract
Sodium glucose co-transporter 2 inhibitors (SGLT2is) are the first class of glucose lowering agent to be shown to reduce cardiovascular events. They are generally well tolerated with infrequent serious adverse events. The most frequent side effect is genital mycotic infections with candida species that are usually mild to moderate in severity, easily treated and infrequently recur. Urinary tract infections, although common in patients with diabetes, have not been shown to be increased in controlled studies with SGLT2i. Hypoglycaemia can occur when an SGLT2i is added to agents that cause hypoglycaemia, such as insulin or sulphonylureas. Volume depletion and hypotension is infrequent and can be minimized by adjusting diuretic and antihypertensive treatment in patients at risk. Acute renal failure or kidney injury was observed in early observational studies. However, in randomized controlled trials (RCTs) and in more recent observational studies a decreased incidence of acute kidney injury was observed in SGLT2-treated patients compared to those receiving either placebo or another class of glucose lowering agents. An increased incidence of amputation (largely feet and toes) was observed in the RCT with canagliflozin but not with the other SGLT2i. Observational studies have shown either an increased risk of amputation with other agents whereas another study showed no increase. Although the increased risk of amputation is very low, avoidance of SGLT2i in patients at high risk seems prudent. Increased incidence of fractures was observed with canagliflozin but not with SGLT2i nor in a meta-analysis that included canagliflozin, empagliflozin and dapagliflozin. No increased incidence of cancer has been observed in either RCTs or observational studies.

Abstract
AIMS/INTRODUCTION The prevalence and risk of vaginal candidiasis before and after initiating sodium-glucose cotransporter 2 (SGLT2) inhibitors, although some clinical trials have been carried out, have not been adequately shown in real-world practice. We investigated the incidence of vaginal Candida colonization and symptomatic vaginitis, and the clinical risk factors including diabetic microvascular complications. MATERIALS AND METHODS The participants were 114 women with type 2 diabetes who were free of vaginitis symptoms and started SGLT2 inhibitors. Vaginal candidiasis tests through self-administered swabs were carried out at baseline, 6 and 12 months. RESULTS Before starting SGLT2 inhibitors, 17 participants (14.9%) had positive vaginal Candida colonization. Younger age and the presence of microangiopathy were significantly associated with the positive colonization in multivariate analysis. Among all participants, 23 (20.2%, 8 because of vaginitis and 15 for other reasons) discontinued SGLT2 inhibitors before reaching the 6-month test. Of 65 participants who were negative for Candida at baseline and received the 6-month test, 24 (36.9%) converted to a positive culture, and multivariate analysis showed older age as an independent risk for developing Candida colonization. There were 18 participants (15.8%) who developed symptomatic vaginitis, and they showed similar characteristics to the 24 participants. Most of those with negative cultures at 6 months showed negative results at 12 months and vice versa. CONCLUSIONS The rates of developing positive colonization and symptomatic vaginitis after starting SGLT2 inhibitors appear to be higher in real-world practice than the rates of 31% and 5-10% in clinical trials, respectively. Risk factors of vaginal Candida colonization might be different before and after taking SGLT2 inhibitors.

Abstract
Candidiasis has increased substantially worldwide over recent decades and is a significant cause of morbidity and mortality, especially among critically ill patients. Diabetes mellitus (DM) is a metabolic disorder that predisposes individuals to fungal infections, including those related to Candida sp., due to a immunosuppressive effect on the patient. This review aims to discuss the latest studies regarding the occurrence of candidiasis on DM patients and the pathophysiology and etiology associated with these co-morbidities. A comprehensive review of the literature was undertaken. PubMed, Scopus, Elsevier’s ScienceDirect, and Springer’s SpringerLink databases were searched using well-defined search terms. Predefined inclusion and exclusion criteria were applied to classify relevant manuscripts. Results of the review show that DM patients have an increased susceptibility to Candida sp. infections which aggravates in the cases of uncontrolled hyperglycemia. The conclusion is that, for these patients, the hospitalization periods have increased and are commonly associated with the prolonged use of indwelling medical devices, which also increase the costs associated with disease management.

Abstract
A 38-year-old female patient with well-controlled type 2 diabetes mellitus treated with canagliflozin underwent ureteral stent placement for obstructive renal calculi. Ten days following ureteroscopy and ureteral stenting, she developed fevers and blood cultures grew Candida glabrata (C. glabrata). The patient was successfully treated with an extended course of broad-spectrum antibiotics and antifungal agents. The clinical presentation of candidemia is indistinguishable from bacteremia resulting in delay in diagnosis and treatment. Candiduria is commonly seen in patients with type 2 diabetes, however it rarely leads to candidemia in an otherwise healthy person following a relatively simple urologic procedure. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors act by its glycosuric effect and further increases the risk of genitourinary candida infection. Urologic procedures may lead to bloodstream entry of the genitourinary fungal organisms and result in life-threatening fungemia. Our case emphasizes the importance of awareness of the increased risk of potentially life threatening fungemia in patients using SGLT-2 inhibitors to avoid delay in diagnosis and treatment.

Abstract
Diabetes is a metabolic disorder characterized by hyperglycemia and is associated with several comorbidities and complications. Genital infection is one such complication that is often associated with diabetes mellitus (DM). Even though abnormalities in immune system, high urine glucose, and bladder dysfunction are important contributors for the increased risk of genitourinary symptoms, yet the possible role of pharmacologically induced glucosuria cannot be completely overlooked in such patients. There are various classes of medications to control blood glucose levels. A new therapeutic option to manage hyperglycemia is to increase renal glucose excretion by inhibiting sodium-glucose cotransporter-2 (SGLT2) glucose transport proteins. SGLT2 inhibitors (SGLT2i) represent a novel class of oral antidiabetic drugs which are associated with drug-induced glucosuria. Currently, canagliflozin, dapagliflozin, and empagliflozin are the three SGLT2i approved for therapy in Type 2 DM (T2DM). Safety studies with these three SGLT2i have reported events of mild-moderate genital infections in patients on SGLT2i therapy. However, most of the reported infections responded to standard treatment. Apart from SGLT2i, factors including personal hygiene, menopause, and circumcision might have a possible role in reported events of genital infections among T2DM patients on SGLT2i therapy. The present review identifies the occurrence of genital infections in diabetic patients on SGLT2i therapy, factors affecting the incidence of genital infections, and management strategies in patients with T2DM on SGLT2i therapy.

Abstract
Recurrent vulvovaginal candidiasis is a debilitating, long-term condition that can severely affect the quality of life of affected women. No estimates of the global prevalence or lifetime incidence of this disease have been reported. For this systematic review, we searched PubMed, Embase, and Web of Science databases for population-based studies published between 1985 and 2016 that reported on the prevalence of recurrent vulvovaginal candidiasis, defined as four or more episodes of the infection every year. We identified 489 unique articles, of which eight were included, consisting of 17 365 patients from 11 countries. We generated estimates of annual global prevalence, estimated lifetime incidence and economic loss due to recurrent vulvovaginal candidiasis, and predicted the number of women at risk to 2030. Worldwide, recurrent vulvovaginal candidiasis affects about 138 million women annually (range 103-172 million), with a global annual prevalence of 3871 per 100 000 women; 372 million women are affected by recurrent vulvovaginal candidiasis over their lifetime. The 25-34 year age group has the highest prevalence (9%). By 2030, the population of women with recurrent vulvovaginal candidiasis each year is estimated to increase to almost 158 million, resulting in 20 240 664 extra cases with current trends using base case estimates in parallel with an estimated growth in females from 3·34 billion to 4·181 billion. In high-income countries, the economic burden from lost productivity could be up to US$14·39 billion annually. The high prevalence, substantial morbidity, and economic losses of recurrent vulvovaginal candidiasis require better solutions and improved quality of care for affected women.

Abstract
Purpose. To explore risk factors of vulvovaginal candidiasis (VVC) among women of reproductive age in Xi'an district and then to offer reference for clinical prevention and treatment of VVC. Methods. Patients from the outpatient department of gynecology and obstetrics in the First Affiliated Hospital of Xi'an Jiaotong University from June 2016 to May 2017 were recruited strictly according to the inclusion and exclusion criteria. Participants diagnosed as simple VVC were assigned to the case group, while women who underwent routine gynecological examination and had normal vaginal microflora were assigned to the control group. Then we conducted a questionnaire survey of the two groups and used the logistic regression model to explore the related risk factors of VVC. Results. In the present study, ninety-seven cases were sample VVC patients and eighty-seven cases were healthy women. This cross-sectional study showed that occasionally or never drinking sweet drinks (odds ratio [OR] =0.161, 95% confidence interval [CI] =0.056-0.462, P=0.001), occasionally or never eating sweet foods (OR=0.158, 95%CI=0.054-0.460, P=0.001), and the use of condom (OR=0.265, 95%CI=0.243-0.526, P=0.001) were regarded as protective factors for VVC. In addition, sedentary life style (OR=7.876, 95%CI=1.818-34.109, P=0.006), frequently wearing tights (OR=6.613, 95%CI=1.369-27.751, P=0.018), frequent intravaginal douching (OR=3.493, 95%CI=1.379-8.847, P=0.008), having the first sexual encounter when under 20 years old (OR=2.364, 95%CI=1.181-7.758, P=0.006), the number of sexual partners being over two (OR=3.222, 95%CI=1.042-9.960, P=0.042), history of curettage (OR=3.471, 95%CI=1.317-9.148, P=0.012), history of vaginitis (OR=8.999, 95%CI=2.816-28.760, P<0.001), and not cleaning the vulva before or after sexual encounters (OR=13.684, 95%CI=2.843-65.874, P=0.001) were considered to be risk factors of VVC. Conclusion. In conclusion, risk factors of VVC are various, involving ages, hygienic habits, disease history, and other aspects.

Abstract
Vaginal complaints are one of the most common reasons women seek the advice of a health care provider. Uncomplicated infections such as vulvovaginal candidiasis, bacterial vaginosis, or trichomoniasis are easy to diagnose and treat. However, about 8% of patients will have a more complicated course with failure to respond to treatment or rapid recurrence of symptoms. Understanding the need for a methodical, diagnostic approach to help these women with recurrent or refractory cases of vaginal symptoms will aid the clinician achieve successful patient outcomes.

Abstract
We studied host factors that could predispose women to develop recurrent vulvovaginal candidiasis (RVVC), including glycemia, insulin resistance, chronic stress, antioxidant capacity, overall immune status, local inflammation and vaginal microbiota. The presence of yeasts in vaginal culture was screened in 277 women, with or without signs and symptoms of VVC and RVVC. The presence of an inflammatory process and microbiota were analyzed through vaginal bacterioscopy and cervical-vaginal cytology, respectively. Fasting-blood samples were collected by standard venipuncture for biochemical analyses. Flow cytometry was employed to obtain the T helper/T cytotoxic lymphocyte ratio, and insulin resistance was assessed by the HOMA index (HI). Yeasts were isolated from 71 (26%) women: 23 (32.4%) with a positive culture but without symptoms (COL), 22 (31%) in an acute episode (VVC), and 26 (36.6%) with RVVC. C. albicans was the main yeast isolated in all clinical profiles. The control group (negative culture) comprised 206 women. Diabetes mellitus and insulin resistance were more associated with the positive-culture groups (COL, VVC and RVVC) than with negative ones. The RVVC group showed lower mean levels of cortisol than the control group and lower antioxidant capacity than all other groups. The T Helper/T cytotoxic lymphocyte ratio was similar in all groups. The RVVC group showed a similar level of vaginal inflammation to the control group, and lower than in the COL and VVC groups. Only the CVV group showed a reduction in vaginal lactobacillus microbiota. Our data suggest that both chronic stress (decreased early-morning cortisol levels) and reduced antioxidant capacity can be host predisposing factors to RVVC.

Adverse drug events observed in patients with type 2 diabetes mellitus treated with 100 mg versus 300 mg canagliflozin: a systematic review and meta-analysis of published randomized controlled trials. BMC Pharmacol Toxicol 2017; 18:19. [PMID: 28411624 PMCID: PMC5392384 DOI: 10.1186/s40360-017-0126-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2016] [Accepted: 02/28/2017] [Indexed: 12/15/2022] Open
Abstract
Background Nowadays, canagliflozin monotherapy, or in combination with other oral hypoglycemic agents (OHAs), is often administered in patients who are treated for type 2 diabetes mellitus (T2DM). Therefore, we aimed to systematically compare the adverse drugs events (AEs) which were associated with 100 mg versus 300 mg canagliflozin respectively, using a large number of randomized patients with T2DM which were obtained from published trials. Methods Randomized controlled trials (RCTs) comparing 100 mg versus 300 mg canagliflozin in patients who were treated for T2DM were searched from electronic databases. AEs reported during a follow up period ranging from 12 to 104 weeks were considered as the clinical endpoints in this analysis. We calculated odds ratios (OR) with 95% confidence intervals (CIs) and the analyses were carried out by RevMan 5 · 3 software. Results Ten trials involving a total number of 5394 patients (2604 patients who were treated with 100 mg canagliflozin and 2790 patients who were treated with 300 mg canagliflozin) were included. The current results showed that serious AEs were not significantly higher in patients who were treated by 300 mg canagliflozin, with OR: 1.01, 95% CI: 0.79–1.29; P = 0.93. Also, a similar rate of death was observed in patients who were treated by either 100 or 300 mg canagliflozin with OR: 1.13, 95% CI: 0.43–2.94; P = 0.80. Urinary tract infections, postural dizziness and hypoglycemia were also similarly manifested, with OR: 0.93, 95% CI: 0.70–1.23; P = 0.61, OR: 1.51, 95% CI: 0.42–5.37; P = 0.53 and OR: 0.96, 95% CI: 0.81–1.13; P = 0.60 respectively. However, drug discontinuation due to AEs significantly favored 100 mg canagliflozin only during this unequal follow-up period with OR: 1.35, 95% CI: 1.06–1.72; P = 0.01, but it was not significantly different when trials with similar follow-up periods were analyzed. Conclusion 300 mg canagliflozin was not associated with significantly higher adverse events compared to 100 mg canagliflozin in those patients who were treated for T2DM. However, because this result was partly affected by other anti-diabetic medications which were included in the treatment regimen, further studies based on patients who were treated strictly on canagliflozin monotherapy should be recommended to completely solve this issue.

Abstract
OBJECTIVE To assess the economic impact of urinary tract infections (UTIs) and genital mycotic infections (GMIs) among patients with type 2 diabetes mellitus (T2DM) initiated on canagliflozin. METHODS Administrative claims data from April 2013 through June 2014 MarketScan® databases were extracted. Adults with ≥1 claim for canagliflozin, T2DM diagnosis, and ≥90 days enrollment before and after canagliflozin initiation were propensity score matched to controls with T2DM initiated on other anti-hyperglycemic agents (AHAs). UTI and GMI healthcare costs were evaluated 90-days post-index and reported as cohort means. RESULTS Rates of UTI claims 90 days post-index were similar in patients receiving canagliflozin for T2DM (n = 31,257) and matched controls (2.7% vs 2.8%, p = .677). More canagliflozin than control patients had GMI claims (1.2% vs 0.6%, p < .001) and antifungal utilization (5.3% vs 2.6%, p < .001). Mean post-index costs to treat UTIs were lower but not significantly different for canagliflozin patients vs matched controls ($27.61 vs $37.33, p = .150). GMI treatment costs were higher for the canagliflozin cohort ($3.68 vs $2.44, p = .041). Combined costs to treat either UTI and/or GMI averaged $31.29 per patient for the canagliflozin cohort v $39.77 for controls (p = .211). Rates and costs of UTIs and GMIs were higher for females than males, but the canagliflozin vs control trends observed for the overall sample were similar for both sexes. There were no significant cost differences between the canagliflozin and control cohorts among patients aged 18-64. Among patients aged 65 and above, GMI treatment costs were not significantly different, but costs to treat UTIs and either UTI and/or GMI were significantly lower for canagliflozin patients vs controls. CONCLUSIONS In a real-world setting, the costs to payers of treating UTIs and GMIs are generally similar for patients with T2DM initiated on canagliflozin vs other AHAs.

Abstract
AIMS To evaluate the effects of different sodium-glucose co-transporter 2 (SGLT2) inhibitors on the risk of urinary tract infections (UTIs) and genital infections in patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS We systematically searched PubMed, Embase, CENTRAL, and ClinicalTrials.gov from inception to October 9, 2016 to identify randomized controlled trials (RCTs) reporting the occurrence of UTIs and genital infections in patients with T2DM treated with SGLT2 inhibitors. Pairwise and network meta-analyses were performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Meta-regression was performed to assess explanatory factors that might influence effect size. RESULTS A total of 52 RCTs involving 36 689 patients were eligible for our meta-analysis. Canagliflozin, dapagliflozin and empagliflozin were associated with a higher risk of genital infections than placebo, with ORs ranging from 3.21 (95% CI 2.08-4.93) for dapagliflozin 2.5 mg to 5.23 (95% CI 3.86-7.09) for canagliflozin 300 mg. Only dapagliflozin 10 mg led to significantly more UTIs than placebo. The increased risk of UTIs and genital infections seemed to have a dose-response relationship for dapagliflozin only. No factors that had a significant modification effect on these infectious events were detected in meta-regression analysis. CONCLUSIONS The present study found that canagliflozin, dapagliflozin and empagliflozin were associated with a significantly higher risk of genital infections compared with placebo and other active treatments. Only dapagliflozin had a dose-response relationship with UTIs and genital infections.

Abstract
Caring for patients with type 2 diabetes mellitus (T2DM) has entered an era with many recent additions to the regimens used to clinically control their hyperglycemia. The most recent class of agents approved by the Food and Drug Administration (FDA) for T2DM is the sodium–glucose-linked transporter type 2 (SGLT2) inhibitors, which work principally in the proximal tubule of the kidney to block filtered glucose reabsorption. In the few years attending this new class arrival in the market, there has been a great deal of interest generated by the novel mechanism of action of SGLT2 inhibitors and by recent large outcome trials suggesting benefit on important clinical outcomes such as death, cardiovascular disease and kidney disease progression. In this review, we focus on canagliflozin, the first-in-class marketed SGLT2 inhibitor in the USA. In some cases, we included data from other SGLT2 inhibitors, such as outcomes in clinical trials, important insights on clinical features and benefits, and adverse effects. These agents represent a fundamentally different way of controlling blood glucose and for the first time in T2DM care to offer the opportunity to reduce glucose, blood pressure, and weight with effects sustained for at least 2 years. Important side effects include genital mycotic infections and the potential for orthostatic hypotension and rare instances of normoglycemic ketoacidosis. Active ongoing clinical trials promise to deepen our experience with the potential benefits, as well as the clinical risks attending the use of this new group of antidiabetic agents.

Abstract
Sodium-glucose linked transporter 2 (SGLT2) inhibitors are a new and promising class of antidiabetic agents which target renal tubular glucose reabsorption. Their action is based on the blockage of SGLT2 sodium-glucose cotransporters that are located at the luminal membrane of tubular cells of the proximal convoluted tubule, inducing glucosuria. It has been proven that they significantly reduce glycated hemoglobin (HbA1c), along with fasting and postprandial plasma glucose in patients with type 2 diabetes mellitus (T2DM). The glucosuria-induced caloric loss as well as the osmotic diuresis significantly decrease body weight and blood pressure, respectively. Given that SGLT2 inhibitors do not interfere with insulin action and secretion, their efficacy is sustained despite the progressive β-cell failure in T2DM. They are well tolerated, with a low risk of hypoglycemia. Their most frequent adverse events are minor: genital and urinal tract infections. Recently, it was demonstrated that empagliflozin presents a significant cardioprotective effect. Although the SGLT2 inhibitors' efficacy is affected by renal function, new data have been presented that some SGLT2 inhibitors, even in mild and moderate renal impairment, induce significant HbA1c reduction. Moreover, recent data indicate that SGLT2 inhibition has a beneficial renoprotective effect. The role of this review paper is to explore the current evidence on the renal effects of SGLT2 inhibitors.

Abstract
AIMS To review prevalence and significance of urinary tract (UTI) and genital infections (GI) in diabetes and the effects of sodium glucose cotransporter 2 (SGLT-2) inhibitors on these complications. DATA SYNTHESIS The prevalence of asymptomatic bacteriuria (ASB) is 2-3 times higher in diabetic than in non-diabetic women. The treatment of ASB has no impact on the development of UTIs and/or a decline in renal function. Therefore, there is no indication for screening for and/or treatment of ASB. The incidence of UTI is higher and frequently complicated in diabetic patients, particularly in those with longer duration of disease and of older age. There is no consistent evidence of an association between A1c levels, glycosuria and the risk of ASB and/or UTIs. Diabetes is a known risk factor for Candida colonization and GI, and a poor glycemic control is associated with a higher risk. While patients treated with SGLT-2 inhibitors may have a non-significant increased risk of UTI, they have a clearly increased risk of GI; most of these infections are mild, easy to treat, and the rate of recurrence is low. CONCLUSION Diabetic patients are at high risk of UTIs and of GI. Only GI are associated with poor glycemic control. Although patients treated with SGLT-2 inhibitors have an increased 3-5 fold risk of GI, proper medical education can reduce this risk.

Abstract
BACKGROUND Canagliflozin is a new SGLT2 inhibitor which has been approved as an adjunct to diet and exercise for the treatment of adults with type 2 diabetes (T2D) mellitus in more than 30 countries. To evaluate the efficacy and safety of canagliflozin in patients with T2D, we carried out a meta-analysis of phase III clinical trials to offer an additional evidence of the efficacy and safety of canagliflozin for evidence-based clinical practice, strictly restricting the treatment durations to 26 weeks (core period) and 52 weeks (extension period). METHODS Randomized controlled trials (RCTs) published in English were searched in PubMed, Embase, and the Cochrane Library database (before April 2016). The studies reporting the efficacy and safety of canagliflozin in patients with T2DM were considered. Two authors separately performed data extraction. The differences were discussed and resolved. Pooled weighted mean differences (WMDs) or relative risks and 95% confidence intervals (CIs) were computed by using either fixed- or random-effects models. RESULTS At the end of the selection process, 7 RCTs were collected and included in the present analysis. Placebo-subtracted WMDs (%) of glycosylated hemoglobin (HbA1c) were -0.63 (95% CI: -0.77, -0.49) and -0.80 (95% CI: -0.98, -0.62) for canagliflozin 100 and 300 mg, respectively, from baseline to week 26. At week 26, canagliflozin 100 and 300 mg significantly reduced the body weight from baseline when compared with that of placebo, with a WMD of -2.23 and -3.00 in percent changes (P < 0.001 for both). The fasting and postmeal glucose, blood pressure (BP), and triglycerides were also reduced. These reductions were sustained over 52 weeks but had no significant differences between the 100 and 300 mg doses. The overall safety of canagliflozin was good, with the exception of high incidence of genital mycotic infections and osmotic diuresis-related adverse events. CONCLUSION Canagliflozin was found to reduce HbA1c, fasting and postmeal glucose, body weight, BP, and triglycerides, and it was generally well tolerated in patients with T2DM.

Abstract
Therapeutic options for diabetes management have expanded dramatically in the last five years. While there continues to be consensus that lifestyle modification aimed at 5-7% weight loss and metformin are the appropriate first line therapies for type 2 diabetes, there are many options for intensification of diabetes management. The American Diabetes Association (ADA) and the American Association of Clinical Endocrinologists (AACE) have released recent guidelines that prioritize use of the newer classes of medications.1,2 There are a number of considerations in selecting medications, including risk of hypoglycemia, effect on body weight, adverse event profile, renal function, and cost/insurance coverage. The objective of this article is to discuss mechanism, efficacy, and safety for each new class of medications. We conclude with a quick reference for the use of these medications in primary and specialty care, based on their various attributes and patient and provider preferences.

Abstract
We studied host factors that could predispose women to develop recurrent vulvovaginal candidiasis (RVVC), including glycemia, insulin resistance, chronic stress, antioxidant capacity, overall immune status, local inflammation and vaginal microbiota. The presence of yeasts in vaginal culture was screened in 277 women, with or without signs and symptoms of VVC and RVVC. The presence of an inflammatory process and microbiota were analyzed through vaginal bacterioscopy and cervical-vaginal cytology, respectively. Fasting-blood samples were collected by standard venipuncture for biochemical analyses. Flow cytometry was employed to obtain the T helper/T cytotoxic lymphocyte ratio, and insulin resistance was assessed by the HOMA index (HI). Yeasts were isolated from 71 (26%) women: 23 (32.4%) with a positive culture but without symptoms (COL), 22 (31%) in an acute episode (VVC), and 26 (36.6%) with RVVC. C. albicans was the main yeast isolated in all clinical profiles. The control group (negative culture) comprised 206 women. Diabetes mellitus and insulin resistance were more associated with the positive-culture groups (COL, VVC and RVVC) than with negative ones. The RVVC group showed lower mean levels of cortisol than the control group and lower antioxidant capacity than all other groups. The T Helper/T cytotoxic lymphocyte ratio was similar in all groups. The RVVC group showed a similar level of vaginal inflammation to the control group, and lower than in the COL and VVC groups. Only the CVV group showed a reduction in vaginal lactobacillus microbiota. Our data suggest that both chronic stress (decreased early-morning cortisol levels) and reduced antioxidant capacity can be host predisposing factors to RVVC.
