Urinary tract infections in patients with diabetes treated with dapagliflozin

Dapagliflozin prevents reproductive damage caused by acute systemic inflammation through antioxidant, anti-inflammatory, and antiapoptotic mechanisms

Dapagliflozin (DPG) is a sodium-glucose cotransporter-2 (SGLT2) inhibitor that has been suggested to possess anti-inflammatory properties in diabetes. The aim of this study is to evaluate the role of DPG administration in preventing lipopolysaccharide (LPS)-induced damage in the female genital system. Thirty-two female Wistar Albino rats were randomly allocated into four groups: control group, LPS group, LPS + DPG group and DPG group. At the end of the experimental phase, ovary, fallopian tube and uterus tissues were collected for histopathological, immunohistochemical, genetic and biochemical analyses. The findings showed that LPS caused histopathological changes characterized by marked hyperaemia, mild to moderate haemorrhage, oedema and neutrophil leucocyte infiltrations and degenerative and necrotic changes in the female genital tract. In addition, it decreased total antioxidant status (TAS), increased total oxidant status (TOS) and oxidative stress index (OSI) levels. LPS also increased the expressions of Cas-3, G-CSF and IL-1β in the ovary, fallopian tubes and uterus immunohistochemically. While Claudin-1 expression decreased, NLRP3 and AQP4 gene expressions increased due to LPS. However, DPG treatment prevented all these changes. The results of this study indicate that, DPG can be used to prevent LPS-induced lesions in the female reproductive system.

Genito Urinary Infection and Urinary Tract Infection in Patients with Type 2 Diabetes Mellitus Receiving SGLT2 Inhibitors: Evidence from a Systematic Literature Review of Landmark Randomized Clinical Trial

BACKGROUND AND PURPOSE

SGLT2 inhibitors are class of drugs that are used in adults with type 2 diabetes through a novel mechanism of action by reducing renal tubular glucose reabsorption, leading to a reduction in blood glucose without stimulating insulin release. In this systematic review, we report the effects of treatment with SGLT2 inhibitors on urinary tract infection (UTI) and genitourinary infection (GUI).

METHOD

The study integrated data from landmark trials of SGLT2 inhibitors (CANVAS, CREDENCE, DECLARE-TIMI 58, and EMPA-REG) to interpret the association of SGLT2 inhibitors with genital infection (GI) and UTI. We reported the review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The primary outcome was a composite of participants reporting UTI and GUI prescribed on SGLT2 inhibitors.

RESULTS

The analysis of four studies involving 38,723 participants revealed incidences of both UTIs and GUI. In the SGLT2 inhibitor group, comprising 21,266 participants, 222 (1.04%) experienced UTIs, and 477 (2.24%) reported GUI. In contrast, among the placebo group consisting of 17,457 participants, 201 (1.15%) reported UTIs, and 70 (0.40%) reported genital infections. These findings underscore the elevated risk associated with SGLT2 inhibitor use, particularly regarding GUI, necessitating careful consideration in clinical practice and patient management strategies.

CONCLUSION

The incidence of UTIs and particularly more pronounced GUI associated with SGLT2 inhibitors highlights the importance of careful risk assessment and monitoring in clinical decision-making, underscoring the need for patient management strategies.

Uropathogens and their antibiotic susceptibility patterns among diabetic patients at st. john of god hospital, duayaw nkwanta, Ghana: a cross-sectional study

Background

Uropathogens are microorganisms that cause urinary tract infections (UTIs). Owing to higher blood glucose levels and compromised immune functions, treatment of uropathogens in diabetic patients is a challenge.

Aim

This study aims to assess the prevalence of uropathogens and their antibiotic susceptibility among diabetic patients at St. John of God Hospital at Duayaw Nkwanta (SJGHDN) in the Ahafo region of Ghana.

Methods

The cross-sectional study recruited 175 diabetic patients at SJGHDN between August and September 2023. Questionnaires were used to collect patients' background information. Fasting Blood Sugar (FBS) was assessed by using a glucometer. Urine samples were examined for the presence of uropathogens. A sterile inoculating loop with a calibrated volume of 2 µl was used for plating. Each colony equals 500 CFU/mL. Significant uropathogen was determined by multiplying the counted colonies by 500 to obtain CFU/mL. Positive uropathogen was defined as CFU ≥ 105/mL. Significant uropathogen was defined as ≥200 colonies per sample. The disc diffusion method was used to determine antibiotic susceptibility.

Results

Out of the 175 patients, 19.4% expressed various uropathogens with Escherichia coli being the predominant. Suboptimal glucose level was the most significant risk factor (p = 0.038). Glucosuria (p = 0.036), hazy urine (p = 0.028), positive leukocyte esterase (p = 0.001), and pus cells in urine sediment (p = 0.020) were significant indicators of uropathogen occurrence. Klebsiella pneumonia and Proteus mirabilis were resistant to ≥4 antibiotics. Amikacin, nitrofurantoin, levofloxacin, ciprofloxacin, and ceftriaxone demonstrated efficacy against the isolates.

Conclusion

This study underscores the notable prevalence of uropathogens in diabetic patients and the alarming levels of antibiotic resistance observed. The results highlight the critical need for vigilant monitoring and customized treatment approaches, particularly for diabetic patients exhibiting risk factors such as elevated urine glucose levels, cloudy urine, and presence of leukocyte esterase and pus cells in urine sediment. The significant resistance to frequently used antibiotics like co-trimoxazole and tetracycline points to the necessity of routine susceptibility testing and the use of alternative antibiotics for effective treatment. These findings can assist healthcare providers in more effectively managing and preventing UTIs in diabetic populations.

Gender Differences in the Clinical Profile of Sodium-Glucose Cotransporter-2 Inhibitor-Related Urinary Tract Infections

Background Sodium-glucose cotransporter-2 inhibitors (SGLT2Is) are a novel class of oral antidiabetic agents with proven cardiovascular and mortality benefits. By promoting glucosuria, SGLT2Is increase the risk of genital and urinary tract infections (UTIs), which remain uncomplicated in most cases. Comparative studies detailing the gender differences in the clinical profile of SGLT2I-related UTIs (SUTIs) are lacking. Hence, this study was designed to investigate the gender-related differences in the clinical profile of SUTIs. Methodology This prospective study enrolled 100 consecutive diabetes mellitus patients with UTI symptoms who were on SGLT2Is. In addition to collecting clinical details, patients were subjected to the following investigations: complete blood counts, urea, creatine, liver function, lipid components, urine analysis, urine culture, and ultrasonography. Results Females (n = 80) outnumbered males (n = 20). Although females were younger than males (53.68 ± 10.26 vs. 63.30 ± 10.75 years, p = 0.003), body mass index (29.84 ± 7.22 vs. 24.62 ± 3.10 kg/m2, p = 0.008) and waist circumference (103.01 ± 14.49 vs. 93.75 ± 4.50 cm, p = 0.109) were higher in females. About 22.5% of females had undergone hysterectomy. The mean duration of diabetes mellitus was longer in males (10.64 ± 6.74 vs. 7.78 ± 4.75 years), whereas the median duration of SGLT2I use (4 (interquartile range (IQR) = 1-12) vs. 3 (IQR = 2-4) months) and mean HbA1c levels were not different between the two groups. A greater proportion of males were complicated by retinopathy (55% vs. 15%) and proteinuria (65% vs. 17.5%), while neuropathy (85% vs. 71.25%) rates were similar. Overall, 35% of males had complicated UTIs (renal abscess, pyelonephritis, prostatic abscess) compared to only 3.75% of females (p = 0.001). Conclusions The majority of SUTIs are uncomplicated in females whereas in males one-third are complicated infections. Although females with SUTI had a higher prevalence of obesity and dyslipidemia, males had a longer duration of diabetes mellitus and higher retinopathy prevalence. Extreme caution should be exercised in patients at risk for SUTI before prescribing SGLT2I.

Diabetes, SGLT-2 Inhibitors, and Urinary Tract Infection: a Review

PURPOSE OF REVIEW

The aim of this review is to focus on epidemiology, pathogenesis, risk factors, management, and complications of UTI in people with diabetes as well as reviewing the association of SGLT-2 inhibitors with genitourinary infections.

RECENT FINDINGS

Individuals diagnosed with T2DM are more prone to experiencing UTIs and recurrent UTIs compared to individuals without T2DM. T2DM is associated with an increased risk of any genitourinary infections (GUI), urinary tract infections (UTIs), and genital infections (GIs) across all age categories. SGLT2 inhibitors are a relatively new class of anti-hyperglycemic agents, and studies suggest that they are associated with an increased risk of genitourinary infections. The management of diabetes and lifestyle modifications with a patient-centric approach are the most recognized methods for preventing critical long-term complications including genitourinary manifestations of diabetes. The available data regarding the association of SGLT-2 inhibitors with genitourinary infections is more comprehensive compared to that with UTIs. Further research is needed to better understand the mechanisms underlining the association between SGLT-2 inhibitors and genital infections and UTIs.

Adverse effects of sodium-glucose cotransporter-2 inhibitors in patients with heart failure: a systematic review and meta-analysis

Sodium-glucose cotransoporter-2 inhibitors (SGLT-2Is) improve prognosis in heart failure (HF) patients both with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). However, these drugs can have some side effects. To estimate the relative risk of side effects in HF patients treated with SGLT-2Is irrespective from left ventricular EF and setting (chronic and non-chronic HF). Five randomized controlled trials (RCTs) enrolling patients with HFrEF, 4 RCTs enrolling non-chronic HF, and 3 RCTs enrolling HFpEF were included. Among side effects, urinary infection, genital infection, acute kidney injury, diabetic ketoacidosis, hypoglycemia, hyperkalemia, hypokalemia, bone fractures, and amputations were considered in the analysis. Overall, 24,055 patients were included in the analysis: 9020 (38%) patients with HFrEF, 12,562 (52%) with HFpEF, and 2473 (10%) with non-chronic HF. There were no differences between SGLT-2Is and placebo in the risk to develop diabetic ketoacidosis, hypoglycemia, hyperkalemia, hypokalemia, bone fractures, and amputations. HFrEF patients treated with SGLT-2Is had a significant reduction of acute kidney injury (RR = 0.54 (95% CI 0.33-0.87), p = 0.011), whereas no differences have been reported in the HFpEF group (RR = 0.94 (95% CI 0.83-1.07), p = 0.348) and non-chronic HF setting (RR = 0.79 (95% CI 0.55-1.15), p = 0.214). A higher risk to develop genital infection (overall 2.57 (95% CI 1.82-3.63), p < 0.001) was found among patients treated with SGLT-2Is irrespective from EF (HFrEF: RR = 1.96 (95% CI 1.17-3.29), p = 0.011; HFpEF: RR = 3.04 (95% CI 1.88-4.90), p < 0.001). The risk to develop urinary infections was increased among SGLT-2I users in the overall population (RR = 1.13 (95% CI 1.00-1.28), p = 0.046) and in the HFpEF setting (RR = 1.19 (95% CI 1.02-1.38), p = 0.029), whereas no differences have been reported in HFrEF (RR = 1.05 (95% CI 0.81-1.36), p = 0.725) and in non-chronic HF setting (RR = 1.04 (95% CI 0.75-1.46), p = 0.806). SGLT-2Is increase the risk of urinary and genital infections in HF patients. In HFpEF patients, the treatment increases the risk of urinary infections compared to placebo, whereas SGLT-2Is reduce the risk of acute kidney disease in patients with HFrEF.

Emphysematous Kidney Related to the Use of Empagliflozin in a Diabetic Woman

Background/Objective

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are part of the treatment for hyperglycemia in patients with diabetes. These drugs have shown important benefits including cardiovascular and renal protection among people with diabetes.

Case Report

We report a case of a 60-year-old woman with diabetes who presented to the emergency department complaining of left flank pain radiating to the groin. The patient was on multiple antidiabetic medications, including a recently added empagliflozin, considering the difficulty in controlling hyperglycemia. She quickly developed severe sepsis with shock, and imaging studies of the abdomen revealed the presence of encapsulated gas in the left kidney compatible with emphysematous pyelonephritis (EPN). There was no presence of nephrolithiasis or other anatomical or structural abnormality that could have precipitated this focal renal infection.Besides antimicrobials, fluid resuscitation, and vasopressor agents, an emergent surgical nephrectomy, as well as intensive care, was required until the patient fully recovered. Escherichia coli was isolated from the initial blood cultures, and ceftriaxone was administered. The patient was subsequently discharged home in stable condition. Two months later, the patient was readmitted with near-syncope and abdominal pain, which was found to be related to small bowel obstruction. The patient decompensated rapidly and had a cardiac arrest even before surgical evaluation. She was resuscitated and admitted to the intensive care unit but showed no signs of neurologic recovery after the anoxic event. She did not survive this hospitalization.

Discussion

The exposure of SGLT2 inhibitors in this patient seemed to have been the precipitating factor for development of complicated pyelonephritis with gas gangrene. EPN is a consequence of a severe renal parenchymal infection, which carries high mortality even with prompt treatment.

Conclusion

Use of SGLT2 inhibitors has expanded worldwide as there are clear clinical benefits, but we need to recognize their uncommon yet potentially fatal complications, such as EPN.

A multicentre, prospective, non-interventional study evaluating the safety of dapagliflozin in patients with type 2 diabetes in routine clinical practice in China (DONATE)

BACKGROUND

There are few large-scale studies evaluating the safety of the sodium-glucose cotransporter-2 inhibitor, dapagliflozin, in Chinese patients with type 2 diabetes. DONATE, a multicentre, single-arm, prospective, non-interventional study, is the first real-world study evaluating the safety of dapagliflozin in Chinese patients with type 2 diabetes in routine clinical practice.

METHODS

Between August 2017 and July 2020, patients with type 2 diabetes who had initiated dapagliflozin therapy and received ≥1 dose were prospectively recruited from 88 hospitals in China. Patients were subsequently followed up for 24 weeks; if patients discontinued dapagliflozin they were followed up for an additional 7 days after treatment discontinuation. The primary outcome was the proportion of patients with adverse events and serious adverse events, particularly key adverse events of special interest (AESI) including urinary tract infection, genital tract infection (typical symptoms with or without microbiological diagnosis) and hypoglycaemia (typical symptoms with or without blood glucose ≤3.9 mmol/L, or blood glucose ≤3.9 mmol/L without symptoms). Exploratory outcomes included the absolute change in metabolic parameters and the proportion of patients with other AESI including volume depletion, abnormal blood electrolytes, polyuria, renal impairment, diabetic ketoacidosis, hepatic impairment and haematuria.

RESULTS

A total of 3000 patients were enrolled, of whom 2990 (99.7%) were included in the safety analysis set. Mean (SD) age was 52.6 (12.0) years, and 65.8% of patients were male. Mean (SD) duration of type 2 diabetes at enrolment was 8.4 (7.1) years. Mean (SD) treatment duration of dapagliflozin was 209.1 (157.6) days. Adverse events were reported in 35.4% (n = 1059) of patients during the 24-week follow-up period. Overall, 9.0% (n = 268) were related to treatment and 6.2% (n = 186) were serious. Urinary tract infection, genital tract infection and hypoglycaemia were reported in 2.3% (n = 70), 1.3% (n = 39) and 1.1% (n = 32) of patients, respectively. The proportion of patients with other AESI was also low: polyuria (0.7%; n = 21), volume depletion (0.3%; n = 9), renal impairment (0.3%; n = 8), hepatic impairment (0.2%; n = 7), haematuria (0.2%; n = 6) and diabetic ketoacidosis (0.1%; n = 2).

CONCLUSIONS

This study demonstrated that once-daily dapagliflozin was well tolerated in Chinese patients with type 2 diabetes and the overall safety profile of dapagliflozin in clinical practice in China was consistent with that reported in clinical trials.

Efficacy and safety of luseogliflozin in Caucasian patients with type 2 diabetes: results from a phase III, randomized, placebo-controlled, clinical trial

INTRODUCTION

Most data demonstrating the efficacy and safety of luseogliflozin (luseo) in people with type 2 diabetes mellitus (T2DM) originate from the Japanese population. This study evaluated luseo versus placebo (PCB) as add-on to metformin in a Caucasian population with inadequately controlled T2DM.

RESEARCH DESIGN AND METHODS

This was a multicenter, randomized, double-blind, PCB-controlled, parallel-group study. Patients aged 18-75 years with inadequately controlled T2DM (glycated hemoglobin (HbA1c) ≥7% to ≤10% (≥53 to ≤86 mmol/mol)) despite a diet and exercise program and on a stable metformin regimen were eligible. Patients were randomized to one of three luseo groups (2.5, 5.0 and 10.0 mg) or PCB for 12 weeks (W12). The primary endpoint was change in HbA1c expressed as least-square means from baseline (W0) to W12.

RESULTS

A total of 328 patients were randomized: PCB (n=83) and luseo 2.5 mg (n=80), 5.0 mg (n=86), and 10.0 mg (n=79). Mean age (±SD) was 58.5±8.8 years; 64.6% were women; body mass index was 31.5±3.4 kg/m2; and HbA1c was 8.54±0.70. At W12, mean reductions in HbA1c from W0 were -0.98%, -1.09%, -1.18%, and -0.73% in the luseo 2.5, 5.0 and 10.0 mg, and PCB groups, respectively, all of which were statistically significant. Compared with PCB, HbA1c levels were significantly decreased by 0.25% (p=0.045), 0.36% (p=0.006), and 0.45% (p=0.001) in the luseo 2.5, 5.0, and 10.0 mg groups, respectively. In all luseo dose groups, reductions in body weight were statistically significant compared with PCB. Data from the safety analysis were consistent with the known luseo safety profile.

CONCLUSIONS

All doses of luseo as add-on to metformin in Caucasian patients with uncontrolled T2DM demonstrated significant efficacy in decreasing HbA1c after W12 of treatment.

Risk of Urinary Tract Infection in Patients with Type 2 Diabetes Mellitus Treated with Dapagliflozin: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND AND OBJECTIVE

To investigate whether dapagliflozin (as a selective inhibitor of sodium-glucose cotransporter 2), increases the risk of urinary tract infection (UTI) in the treatment of type 2 diabetes mellitus (T2DM) remains an ongoing issue. We performed a systematic review and meta-analysis of randomized clinical trials (RCTs) to estimate the short-term and long-term risks of UTI in patients with T2DM who received dapagliflozin at different doses.

METHODS

The PubMed, EMBASE, and the Cochrane Library and ClinicalTrials.gov website were searched up to December 31, 2022. Only RCTs involving adult T2DM patients with a trial duration of at least 12 weeks were included. The data were summarized using random- or fixed-effects models based on overall heterogeneity. A subgroup analysis was also performed. The review protocol was previously registered in the PROSPERO database (CRD42022299899).

RESULTS

In total, 42 RCTs involving 35,938 patients were assessed for eligibility. The results showed that dapagliflozin imposed a higher risk of UTI compared to placebo and other active treatments, with a heterogeneity of 11% (odds ratio [OR] 1.17, 95% CI 1.04-1.31, p = 0.006). In the subgroup analysis, dapagliflozin 10 mg/day with a treatment period of > 24 weeks was associated with a significantly higher UTI risk than placebo or other active treatments (OR 1.27, 95% CI 1.13-1.43, p < 0.0001). The ORs for dapagliflozin as monotherapy and combination therapy in the control group were 1.05 (95% CI 0.88-1.25, p = 0.571) and 1.27 (95% CI 1.09-1.48, p = 0.008), respectively.

CONCLUSIONS

High-dose, long-term treatment, and add-on therapy of dapagliflozin call for careful consideration of the risk of UTI in T2DM patients.

Post-Authorization Safety Studies of Acute Liver Injury and Severe Complications of Urinary Tract Infection in Patients with Type 2 Diabetes Exposed to Dapagliflozin in a Real-World Setting

INTRODUCTION

At the time of dapagliflozin's approval in Europe (2012) to treat patients with type 2 diabetes mellitus, concerns regarding acute liver injury and severe complications of urinary tract infection (sUTI) led to two post-authorization safety (PAS) studies of these outcomes to monitor the safety of dapagliflozin in real-world use.

OBJECTIVE

To investigate the incidence of hospitalization for acute liver injury (hALI) or sUTI (pyelonephritis or urosepsis) among patients initiating dapagliflozin compared with other glucose-lowering drugs (GLDs).

METHODS

These two noninterventional cohort studies identified initiators of dapagliflozin and comparator GLDs in November 2012-February 2019 using data from three longitudinal, population-based data sources: Clinical Practice Research Datalink (UK), the HealthCore Integrated Research Database (USA), and the Medicare database (USA). Outcomes (hALI and sUTI) were identified with electronic algorithms. Incidence rates were estimated by exposure group. Incidence rate ratios (IRRs) were calculated comparing dapagliflozin to comparator GLDs, using propensity score trimming and stratification to address confounding. The sUTI analyses were conducted separately by sex.

RESULTS

In all data sources, hALI and sUTI incidence rates were generally lower in dapagliflozin initiators than comparator GLD initiators. The adjusted IRR (95% confidence interval) pooled across data sources for hALI was 0.85 (0.59-1.24) and for sUTI was 0.76 (0.60-0.96) in females and 0.74 (0.56-1.00) in males. Findings from sensitivity analyses were largely consistent with the primary analyses.

CONCLUSIONS

These real-world studies do not suggest increased risks of hALI or sUTI, and they suggest a potential decreased risk of sUTI with dapagliflozin exposure compared with other GLDs.

Similarities in Bacterial Uropathogens and Their Antimicrobial Susceptibility Profile in Diabetics and Their Non-Diabetic Caregivers at a National Diabetes Management and Research Centre, Accra-Ghana

BACKGROUND

Diabetes mellitus has some damaging effects on the genitourinary system and has been found to have adverse effects on the host immune system, resulting in higher risk of infections including urinary tract infections (UTI). Incidences of UTI caused by bacteria have been increasingly reported globally and the abuse of antibiotics leading to evolving resistant strains of antibiotics is a public health challenge for the management of this condition. Information on the difference in types of bacterial agents causing UTI in diabetic patients and non-diabetic individuals, and their susceptibility profiles, will facilitate effective management among these groups of patients. Therefore, this study aimed at determining the difference in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility profiles in diabetic patients and non-diabetic individuals at a diabetes management center.

METHODS

This was a prospective cross-sectional study conducted amongst 100 diagnosed diabetic patients and 100 non-diabetic individuals. Urine sample was collected aseptically and analyzed microbiologically for the presence of urinary tract bacterial pathogens. Drug susceptibility testing was conducted on the isolates by the Kirby Bauer method to ascertain the antibiotic susceptibility patterns.

RESULTS

Among the diabetic and non-diabetic individuals, urinary tract bacterial pathogens were observed in 28.0% and 26.0% of samples, respectively. The organisms were in the following proportions for diabetic and non-diabetic individuals, respectively: E. coli (14/28, 50% and 8/26, 30.7%), S. aureus (2/28, 7.1% and 4/26, 15.4%), K. pneumoniae (4/28, 14.3% and 8/26, 30.7%), K. ozoenae (2/28, 7.14% and 0/26, 0%), K. oxytoca (0/28, 0% and 4/26, 15.4%) and C. urealyticum (6/28, 21.4% and 2/26, 7.69%). The difference between the proportions of bacteria isolated was, however, not statistically significant (p-value = 0.894). Bacteria isolated from both diabetic and non-diabetic individuals were highly susceptible to most of the antibiotics tested, especially nitrofurantoin, cefuroxime, ceftriaxone, and cefotaxime.

CONCLUSION

This study has shown that similarities exist in prevalence of UTI, the causative bacteria, and their antimicrobial susceptibility patterns amongst diabetic patients and non-diabetic individuals at a diabetes management center. These data will help in the management of UTI among these individuals.

Sodium-Glucose Cotransporter-2 (SGLT-2) Inhibitors and Genital Infections in Patients With Diabetic Mellitus and Concomitant Coronary Artery Disease: A Single-Center Experience

Objective To investigate the incidence of genital infection due to the use of sodium-glucose cotransporter-2 (SGLT-2) inhibitors in patients with type 2 diabetes mellitus (T2DM) concomitant coronary artery diseases (CAD). Methods A single-center, physician-initiated study was conducted at a tertiary-care center in India. The study enrolled patients with T2DM who were taking SGLT-2 inhibitors for at least two months and divided them into two groups: patients with concomitant CAD as the case group and without CAD as the control group. Demographic data and medical history of patients were documented using a standard questionnaire. Itching and swelling were the signs used for the diagnosis of genital infection. Results A total of 270 consecutive patients with T2DM were enrolled and divided into two groups: 48 patients with CAD as the case group and 222 patients without CAD as the control group. The mean age of patients with CAD was 63.27±7.53 years and without CAD was 58.32±14.89 years. The mean HbA1C levels were 8.40±1.71% in the case group and 8.60±7.20% in the control group. A total of 14.6% of patients with CAD and 12.6% of patients without CAD were found to have genital infections (p=0.712). SGLT-2 inhibitors were stopped in only six patients who had genital infections and all the patients were managed using anti-fungal cream and via maintenance of proper hygiene. The overall incidence of genital infection was about 12.96%, of which only 2.7% required discontinuation of this crucial therapy. Conclusion In conclusion, the incidence of genital infection with the use of SGLT-2 inhibitors is similar among patients with T2DM with concomitant CAD and without CAD. The measures to prevent genital infection should be strongly emphasized. However, larger, well-designed studies are required to validate the current findings.

Drug-induced Urinary Retention: An Analysis of a National Spontaneous Adverse Drug Reaction Reporting Database

BACKGROUND

Numerous drugs have been associated with urinary retention (UR), but updated information on drugs that may induce UR is limited.

OBJECTIVE

To evaluate drug-induced UR using the Italian spontaneous adverse drug reactions (ADRs) reporting database.

DESIGN, SETTING, AND PARTICIPANTS

We selected all suspected spontaneous reports of drug-induced UR collected into the Italian spontaneous reporting system (SRS) database from its inception to June 30, 2019.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The Mantel-Haenszel χ² test and the Mann-Whitney U test were performed for statistical comparisons of categorical and continuous variables, respectively. As a measure of disproportionality, we calculated the reporting odds ratios (RORs) with corresponding 95% confidence intervals using a statistical case/noncase methodology.

RESULTS AND LIMITATIONS

A total of 506 383 ADR reports were received in the Italian SRS database during the study period. Of these, 421 reports (0.1%) included UR-related ADRs, for a total of 497 suspected drugs. The median (interquartile range [IQR]) age of patients experiencing UR was 67 (47-77) yr. Overall, 174 (41.3%) ADR reports were considered serious. One-third of male patients experiencing UR suffered from benign prostatic hyperplasia, followed by diabetes mellitus (N = 58, 13.8%), and bladder-related disorders (N = 21, 5.0%). The median lag time between the start of drug treatment and UR onset was 7 (IQR 1-47.5) d. Overall, a statistically significant ROR was reported for 39 individual drugs, and for five (12.8%) of them (dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam) UR was not described in their summary of product characteristics. Limitations include under-reporting and selective over-reporting of suspected ADRs and lacking information on the number of drug users.

CONCLUSIONS

A disproportionality analysis identified five potentially new UR signals for dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam, requiring further evaluation.

PATIENT SUMMARY

In this analysis of the Italian spontaneous reporting system database, we found new urinary retention signals, requiring further evaluation, for dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam.

Alternate day add on therapy with dapagliflozin in patients with type 2 diabetes mellitus: potential benefits and concerns

INTRODUCTION

Factors like compliance, cost and safety play a major role in achieving the long-term goal in the management of type 2 diabetes mellitus (T2DM). Dapagliflozin carries great potential of becoming an alternate day therapy because of its favorable pharmacokinetic profile and other properties.

AREAS COVERED

In this review, we have discussed and hypothesized the potential of dapagliflozin as an alternate day add-on drug in T2DM patients. We have discussed the properties by virtue of which it carries a potential to become an alternate day therapy. We have also explained the potential benefits and concerns of using this approach.

EXPERT OPINION

Alternate day add-on therapy with dapagliflozin could be a promising approach in reducing the cost, improving the treatment satisfaction and reducing the adverse effects. It may be a cost-effective option for T2DM patients and demands an in-depth investigation among T2DM subjects who are not able to achieve glycemic control with initial therapy with standard monotherapy or combination therapy. Pilot studies or some small-scale investigator initiated trial or academic clinical trials may be carried out to explore this concept. At the same time large industry sponsored multicenter RCTs including pharmacoeconomic analyses may be planned to have a more detailed investigation.

Sodium-Glucose Cotransporter-2 Inhibitor-Related Diabetic Ketoacidosis: Accuracy Verification of Operational Definition

BACKGROUND

The most important aspect of a retrospective cohort study is the operational definition (OP) of the disease. We developed a detailed OP for the detection of sodium-glucose cotransporter-2 inhibitors (SGLT2i) related to diabetic ketoacidosis (DKA). The OP was systemically verified and analyzed.

METHODS

All patients prescribed SGLT2i at four university hospitals were enrolled in this experiment. A DKA diagnostic algorithm was created and distributed to each hospital; subsequently, the number of SGLT2i-related DKAs was confirmed. Then, the algorithm functionality was verified through manual chart reviews by an endocrinologist using the same OP.

RESULTS

A total of 8,958 patients were initially prescribed SGLT2i. According to the algorithm, 0.18% (16/8,958) were confirmed to have SGLT2i-related DKA. However, based on manual chart reviews of these 16 cases, there was only one case of SGLT2i-related DKA (positive predictive value = 6.3%). Even after repeatedly narrowing the diagnosis range of the algorithm, the effect of a positive predictive value was insignificant (6.3-10.0%, P > 0.999).

CONCLUSION

Owing to the nature of electronic medical record data, we could not create an algorithm that clearly differentiates SGLT2i-related DKA despite repeated attempts. In all retrospective studies, a portion of the samples should be randomly selected to confirm the accuracy of the OP through chart review. In retrospective cohort studies in which chart review is not possible, it will be difficult to guarantee the reliability of the results.

The prevalence of urinary tract infections in type 2 diabetic patients: a systematic review and meta-analysis

Background

Urinary tract infection is the most common infection in type 2 diabetic patients. Various studies have reported different outbreaks of urinary tract infections in type 2 diabetic patients. Therefore, the present study aimed to determine the prevalence of urinary tract infections in type 2 diabetic patients during a systematic review and meta-analysis in order to develop interventions to reduce the incidence of urinary tract infections in type 2 diabetic patients.

Methods

In this study, systematic review and meta-analysis of study data related to the prevalence of urinary tract infection in type 2 diabetic patients were conducted using keywords including type 2 diabetes, urinary tract infection, diabetes, prevalence, meta-analysis and their English equivalents in SID, MagIran, IranMedex, IranDoc, Google Scholar, Cochrane, Embase, Science Direct, Scopus, PubMed and Web of Science (WoS) databases from 1993 to 2020. In order to perform the analysis of qualified studies, the model of random-effects was used, and the inconsistency of studies with the I2 index was investigated. Data analysis was performed with Comprehensive Meta-Analysis (Version 2).

Results

Based on a total of 15 studies with a sample size of 827,948 in meta-analysis, the overall prevalence of urinary tract infection in patients with type 2 diabetes was 11.5% (95% confidence interval: 7.8–16.7%). The prevalence of urinary tract infections in diabetic Iranian patients increased with increasing number of years of research, (p < 0.05), and with increasing age of participants (p < 0.05), but however the prevalence decreased with increasing sample size (p < 0.05).

Conclusion

This study shows that urinary tract infections are highly prevalent in patients with type 2 diabetes. Therefore, due to the growing prevalence of diabetes and its complications such as urinary tract infections, the need for appropriate screening programs and health care policies is becoming more apparent.

Frequency of Urinary Tract Infections in Type 2 Diabetic Patients Taking Dapagliflozin

Background

Urinary tract infections (UTIs) are common in patients with diabetes. The use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) to achieve good glycemic control increases glucose levels in urine. This glycosuria further enhances the risk of UTIs. This study aimed to evaluate the frequency of UTIs in patients with type 2 diabetes receiving the SGLT2i dapagliflozin as an add-on therapy.

Methods

We conducted this cross-sectional study at the Endocrinology Department of Hayatabad Medical Complex in Peshawar from April 2020 to September 2020. A total of 400 patients with diabetes receiving either 5 mg or 10 mg of dapagliflozin as an add-on therapy for the treatment of type 2 diabetes were included in this study. We collected blood and urine samples from participants and measured glycosylated hemoglobin levels. Urine samples were cultured on cysteine lactose electrolyte deficient agar. We used IBM SPSS Statistics for Windows, version 25.0 (IBM Corp., Armonk, NY) to analyze our data.

Results

The prevalence of UTIs in diabetic patients receiving 5 mg or 10 mg of dapagliflozin was 5.3%. Women were more affected (76.2%) than men (p < 0.05). UTIs were more prevalent in patients older than 50 years (85.7%) than in any other age group. The dose strength of dapagliflozin was not associated with UTIs (p > 0.05).

Conclusion

This study examined UTIs in patients taking dapagliflozin for the treatment of type 2 diabetes. These infections were mild to moderate and were treated easily. None of these infections caused the patient to discontinue the treatment. Dapagliflozin is well-tolerated in patients with diabetes but should be used with appropriate caution and monitoring.

Real-World Assessment of Efficacy and Safety Parameters for Dapagliflozin in Management of Type 2 Diabetes Mellitus: REWARD Study

<b><i>Introduction:</i></b> While ample evidence on improved glycemic control, weight reduction, and lowered blood pressure (BP) with sodium-glucose cotransporter type 2 inhibitors (SGLT2is) exists, real-world data on the potential benefit of SGLT2i on the diabetic population in the Middle East are lacking. The aim of our study was to describe the glycemic control, changes in body weight, body mass index (BMI), lipid profile, and BPs in patients receiving dapagliflozin with other antidiabetic medication. <b><i>Methods:</i></b> The REWARD study was a multicenter, post-authorization, prospective, open-label, noninterventional, real-world, cohort study. We enrolled 511 adult, type 2 diabetes mellitus patients on antidiabetic medications. These patients were started on dapagliflozin and followed up for 1 year to assess changes in their clinical and laboratory outcomes. <b><i>Results:</i></b> The mean HbA1c decreased significantly from 8.5 ± 1.6% at baseline to 7.6 ± 1.3% after 12 months (<i>p</i> value &#x3c;0.001), with an absolute change of 0.9%. Of the study population, 41.6% of patients reached an HbA1c level less than 7% (53 mmol/mol). The systolic pressure improved (mean change = −1.9 mm Hg, <i>p</i> value = 0.003), yet no change in the diastolic pressure was observed. Both body weight and BMI significantly decreased by 0.7 kg and 0.2 kg/m², respectively (<i>p</i> value &#x3c;0.001). About 84.5% of patients were on antidyslipidemic agents, while 57.4% were on antihypertensives. Approximately 83.6% of adverse events were mild. A total of 90 hypoglycemic episodes were reported; none were severe. <b><i>Conclusion:</i></b> In a real-world setting, dapagliflozin in combination with other antidiabetic medications exhibited significant improvement in glycemic control, weight, BMI, and systolic BP. Additionally, it demonstrated a well-tolerated safety profile.

Comparative Assessment of the Long-Term Effectiveness and Safety of Dapagliflozin and Empagliflozin as Add-on Therapy to Hypoglycemic Drugs in Patients with Type 2 Diabetes

BACKGROUND

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduce blood glucose, blood pressure, and body weight in patients with type 2 diabetes (T2D). However, the comparative long-term effectiveness and safety of SGLT2i among similar drugs, administered at different doses, have not been assessed. In this study, we compared the long-term effectiveness and safety of SGLT2i (dapagliflozin versus empagliflozin) as add-on therapy to hypoglycemic agents in T2D patients.

METHODS

This study was a single-center, 3-year, retrospective, observational study. For all patients in the study, drugs were evaluated for safety by documenting adverse drug reactions. The primary effectiveness was evaluated as the difference between hemoglobin A1c (HbA1c) values obtained at baseline and those obtained after 36 months of treatment. The proportion of participants with HbA1c levels <7.0% and <6.5% was also analyzed.

RESULTS

In total, 680 patients were enrolled in this study. Using propensity score matching, 234 patients each from the dapagliflozin and empagliflozin groups were selected based on patient characteristics. After 36 months of treatment, clinical parameters (including HbA1c, fasting plasma glucose, alanine aminotransferase, triglyceride levels, body weight, and systolic blood pressure) decreased significantly in these groups. The changes from the baseline for the physiological values and clinical parameters did not vary among the different dose groups of SGLT2i. The incidence of adverse drug reactions was approximately 7-8%. All patients with observed serious adverse reactions were hospitalized for urinary tract infections.

CONCLUSION

Our study showed that the long-term continuous use of either dapagliflozin or empagliflozin as add-on therapy to hypoglycemic drugs for T2D patients is synergistically effective for lowering blood glucose, reducing body weight, and stabilizing blood pressure. Additionally, there was no significant difference in efficacy between dapagliflozin and empagliflozin, even with the administration of different doses of these agents.

Bacterial drug-resistance patterns and genetic diversity of bacteria-associated bacteriuria in diabetic patients in Ghana

•

An overall UTI prevalence of 9.2% (90/982) was detected in diabetic patients in Ghana.

•

Multidrug-resistant E. coli and Klebsiella spp. are a cause for concern in diabetic patients.

•

Phylo-groups B2 and D were prevalent, followed by group C.

•

The predominant virulence genes observed were iutA (17.9%) and KpsMTIII (14.3%).

•

Phylo-group B2 had the highest number of VFs, and was resistant to most of the tested antibiotics.

Objectives

Our study aimed to determine the etiology of urinary tract infections (UTIs), resistance profiles of isolated bacteria, and virulence factors of Escherichia coli associated with bacteriuria in diabetic patients in Ghana.

Methods

Midstream urine samples from 982 diabetic patients were tested for uropathogens at the National Diabetes Management and Research Centre in Ghana, using standard bacteriological methods, with antibiogram testing of the isolates using the Kirby–Bauer disk diffusion, as per CLSI guidelines. Polymerase chain reaction (PCR) was used to investigate the phylogenetic groupings and virulence factor (VF) genes of isolated E. coli.

Results

The overall prevalence of UTIs was 9.2%, and the main uropathogens were Klebsiella spp. (55.6%) and Escherichia coli (31.3%). Age, duration of diabetes, and a previous history of UTIs were risk factors associated with UTI (p-value < 0.05). High levels of antibacterial resistance to cefuroxime (84%), ampicillin (80%), and gentamicin (70.7%) were observed. The distribution of VFs in each phylogenetic group revealed that sfa-iutA-KpsTMII-KpsTMIII genes were associated with group B2, and iutA-ibe were associated with group D.

Conclusions

The isolated uropathogens were highly resistant, and the E. coli isolates possessed varying VFs. Continuous monitoring of bacteria associated with UTI in diabetics is highly recommended.

Dapagliflozin is a sodium-glucose co-transporter-2 (SGLT2) inhibitors used in the treatment of patients with type 2 diabetes. An aryl glycoside with significant effect as glucose-lowering agents, Dapagliflozin also has indication for patients with Heart Failure and Chronic Kidney Disease. This review examines the structure, synthesis, analysis, structure activity relationship and uses of the product. The studies behind this drug have opened the doors for the new line of treatment – a drug that reduces blood glucoses, decreases the rate of heart failures, and has a positive effect on patients with chronic kidney disease.

Dapagliflozin for the treatment of type 2 diabetes mellitus - an update

INTRODUCTION

Diabetes is a global health concern with a prevalence of 463 million people. Importantly, despite the availability of numerous antidiabetic medications, type 2 diabetes mellitus (T2DM) is still associated with significant morbidity and mortality worldwide. One particular drug of interest is dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor that is commonly used in the treatment of Type 2 Diabetes Mellitus (T2DM).

AREAS COVERED

This review outlines the current use and pharmacology of dapagliflozin, with a specific focus on recent evidence regarding benefits in patients with cardiovascular and chronic kidney disease. The article includes an overview of the efficacy and safety of this drug and provides the reader with the expert opinion and perspectives of the authors.

EXPERT OPINION

Increasing evidence of the beneficial effects on morbidity and mortality in patients with Type 2 diabetes and concurrent heart failure, acute MI and renal failure are likely to see the usage of dapagliflozin in patients with these comorbidities increase over the next 5 years.

Safety of Dapagliflozin in Patients with Type 2 Diabetes Mellitus in Saudi Arabia: A Post Authorization Safety Study

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.

Age- and sex-specific risk of urogenital infections in patients with type 2 diabetes treated with sodium-glucose co-transporter 2 inhibitors: A population-based self-controlled case-series study

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

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.

Diabetes patient’s pharmacovigilance knowledge and risk perception: the influence of being part of a patient organisation

Objective:

The aim was to assess the perception of risk for developing adverse drug reaction (ADRs) and knowledge, attitudes and opinions regarding pharmacovigilance in diabetic patients, and to investigate the effect of being a member of a patient organisation for diabetes on these factors, in comparison with other patients.

Methods:

A cross-sectional study looking for patients’ risk perception of experiencing ADRs. Diabetes patients followed at the Portuguese Diabetes Association (APDP) were included, together with two comparison groups (patients with and without diabetes). Kruskal-Wallis followed by post hoc Dunn’s multiple-comparison test were used to compare patients’ groups.

Results:

A total of 314 patients participated in the survey (104 followed at APDP, 106 with diabetes not followed at APDP and 104 without diabetes diagnosis that used chronic medication). APDP patients presented higher risk perception scores for medicines related to their disease compared with two groups. Those patients affirmed that doctors explained possible ADRs on medication to them, and showed higher intention to report ADRs in the future if serious or unexpected.

Conclusions:

Patients with diabetes showed greater understanding of ADRs and higher need to report them than patients without diabetes. They would like to have more information about general ADRs related to anti-diabetic medication and present higher intention to acquire information on how and when to report compared with non-diabetic patients. Patients followed in APDP presented higher score of risk perception, which could be influenced by the presence of the diabetes disease in the patients’ life, by their previous experiences using medicines, but also by information received from the patient organisation. The two groups of patients with diabetes have different experiences of the disease, but both present higher perception of side effects related with medicines they use respectively in their diabetes type. Hence, patient organisations are well positioned to be a source where patients can obtain reliable information, changing their attitudes and perceptions about the disease and drug treatments.

Prevention and Management of Genital Mycotic Infections in the Setting of Sodium-Glucose Cotransporter 2 Inhibitors

OBJECTIVE

To review the incidence, risk factors, prevention, and management of genital mycotic infections (GMIs) associated with sodium-glucose cotransporter 2 (SGLT2) inhibitors.

DATA SOURCES

A literature search of PubMed and Reactions Weekly was performed in February 2020 with updated searches monthly through July 2020 to identify relevant data regarding SGLT2 inhibitors and GMIs. Manufacturers of each agent were contacted, and clinical practice guidelines were consulted.

STUDY SELECTION AND DATA EXTRACTION

All available literature was evaluated for inclusion based on relevance to the research question, timeliness of the publication, validity, and impact on current practice. A date limit was not set; however, publications from 2010 to July 2020 were prioritized.

DATA SYNTHESIS

The 3- to 4-fold increased incidence of GMIs is considered a classwide effect of SGLT2 inhibitors. Female sex and a prior history of GMIs are factors associated with the highest risk, whereas circumcised males are at the lowest risk of SGLT2 inhibitor-induced GMI. Personal hygiene advice can reduce the infection risk. When candidiasis occurs, it is often mild and responsive to treatment and often does not require discontinuation of the medication.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

This narrative review can assist in shared decision-making discussions with patients who may benefit from SGLT2 inhibitors and provides guidance for health care professionals managing SGLT2 inhibitor-associated GMIs.

CONCLUSIONS

SGLT2 inhibitors predispose patients to developing mild GMIs. Strong consideration should be given to avoid SGLT2 inhibitors in female patients with a history of severe, recurrent infections. Preventive strategies are optimized diabetes management and personal hygiene advice.

Patient Preferences for Medications in Managing Type 2 Diabetes Mellitus: A Discrete Choice Experiment

OBJECTIVES

To quantify patients' maximum acceptable risk (MAR) of urinary and genital tract infections (UGTI) in exchange for benefits associated with treatments for managing type 2 diabetes mellitus (T2DM).

METHODS

In a discrete choice experiment, adult patients with T2DM and currently on metformin and/or sulphonylurea (first-line treatments) were asked to choose between 2 hypothetical medications defined by 6 attributes: years of medication effectiveness in controlling blood glucose, weight reduction, UGTI risk, risk of hospitalization from heart failure, all-cause mortality risk, and out-of-pocket medication cost. We used latent class logistic regression parameters to estimate the conditional relative importance of treatment attributes and MAR of UGTI for various treatment benefits.

RESULTS

A 2-class latent class model was identified as the best fit for the responses from 147 patients. The first class (49% of sample), termed as "survival-conscious," stated that they were willing to accept 46% (95% confidence interval [CI]: 2%-90%) UGTI risk in exchange for a reduction from 6% to 1% in all-cause mortality risk. The second class (51% of sample), termed as "UGTI/cost-conscious" were willing to accept significantly lower (6%; CI: 2%-11%, and 5%; CI: 2%-8%) UGTI risk in exchange for the same reduction in all-cause mortality and hospitalization risks, respectively.

CONCLUSIONS

On average, patients were willing to trade higher UGTI risk for a more effective medication. Our findings suggest that physicians should present the benefits and potential side effects of all available treatments and consider patient preferences in their treatment recommendations.

[Advantages of therapy with sodium glucose cotransporter type 2 inhibitors in patients with type 2 diabetes mellitus in combination with hyperuricemia and gout]

Currently, only two drugs for reducing uric acid (UA), allopurinol and febuxostat, are registered in the Russian Federation, but their use does not allow to achieve the target level of UA in all cases. According to the results of numerous randomized trials, hyperuricemia and gout are associated with the corresponding components of the metabolic syndrome, including diabetes mellitus. The influence of factors is due to the need to search for new drugs that have a complex effect on several components of metabolic syndrome at once. Potentially attractive in this regard is a new group of drugs for the treatment of type 2 diabetes mellitus inhibitors of the sodium-glucose cotransporter of type 2, which, in addition to the main hypoglycemic actions, showed positive effects on the cardiovascular system, kidneys, as well as lowering UA.

A randomized trial of dapagliflozin and metformin, alone and combined, in overweight women after gestational diabetes mellitus

BACKGROUND

Women with a history of gestational diabetes mellitus are at a substantially increased risk of gestational diabetes mellitus recurrence and type 2 diabetes. Weight gain, particularly increased central adiposity after delivery, is strongly associated with deterioration of pancreatic beta cell compensation for insulin resistance. Weight management after gestational diabetes mellitus could have a significant benefit in these women who are at a high risk of developing type 2 diabetes.

OBJECTIVE

This study aimed to evaluate the treatment efficacy of dapagliflozin and metformin, alone and in combination, on body weight and anthropometric, cardiovascular, and metabolic parameters in overweight women with a recent history of gestational diabetes mellitus.

STUDY DESIGN

This was a prospective, single-blind, randomized, outpatient clinical trial with 3 parallel treatment groups. Overweight or obese (body mass index>25) females (n=66; ≥18-45 years) with gestational diabetes mellitus in pregnancy in the past 12 months were randomized in a single-blind manner to dapagliflozin, metformin, or dapagliflozin-metformin for 24 weeks. Body weight, height, body mass index, waist circumference, waist-to-height ratio, and blood pressure were determined at baseline and trial completion. Oral glucose tolerance tests were performed at baseline and 24 weeks to assess glycemia and mean blood glucose and calculate insulin sensitivity and secretion measures. Plasma lipid fractions, thyroid-stimulating hormone, and liver enzymes were also assessed in the fasting sample at the beginning and completion of the study trial.

RESULTS

The study was completed by 49 participants (74%). Significant reduction of weight, waist circumference, and waist-to-height ratio and improved glycemia and insulin sensitivity index derived from oral glucose tolerance test were found with dapagliflozin-metformin vs metformin monotherapy. Both dapagliflozin and dapagliflozin-metformin therapy were superior to metformin in increasing high-density lipoprotein levels, reducing triglyceride concentrations, lowering the triglyceride-to-high-density lipoprotein cholesterol ratio, and improving glucose excursion after an oral glucose tolerance test. The early insulin response to a glucose challenge significantly improved with only dapagliflozin-metformin compared with single-drug treatments.

CONCLUSION

This is the first report comparing the efficacy of a sodium-glucose cotransporter 2 inhibitor alone and in combination with metformin in this patient population. We found that combination dapagliflozin-metformin treatment over a 24-week period had a greater positive effect on body weight, waist circumference, and glycemic, cardiovascular, and metabolic parameters than metformin monotherapy in overweight or obese at-risk women with a recent history of gestational diabetes mellitus.

Efficacy and safety of dapagliflozin in Japanese patients with inadequately controlled type 1 diabetes (DEPICT-5): 52-week results from a randomized, open-label, phase III clinical trial

AIMS

To investigate the safety and tolerability of 5 and 10 mg dapagliflozin added to insulin therapy over 52 weeks in Japanese patients with inadequately controlled type 1 diabetes mellitus (T1DM).

MATERIALS AND METHODS

This randomized, open-label, parallel-group, multicentre phase III clinical trial was conducted from October 26, 2015 to June 15, 2017. The primary endpoint was the occurrence of adverse events such as hypoglycaemia and diabetic ketoacidosis. Secondary endpoints included changes in glycaemic parameters, total daily insulin dosage and body weight over time. The efficacy of dapagliflozin in patients stratified by body mass index (BMI) <25.0 and ≥25.0 kg/m² was evaluated in a subgroup analysis.

RESULTS

In total, 151 patients received 5 mg (n = 76) or 10 mg (n = 75) dapagliflozin once daily for 52 weeks. Adverse events were observed in 88.2% and 73.3% of patients in the 5 and 10 mg dapagliflozin groups, respectively. Severe hypoglycaemia was reported in 2.6% (n = 2) and 6.7% (n = 5) of patients, and diabetic ketoacidosis in 2.6% (n = 2) and 1.3% (n = 1) of patients in the 5 and 10 mg dapagliflozin groups, respectively. The adjusted mean (95% confidence interval) changes in glycated haemoglobin at week 52 were -0.33% (-0.50, -0.15) and -0.36% (-0.53, -0.18) in the 5 and 10 mg dapagliflozin groups, respectively. There were no differences in efficacy parameters when stratified by BMI.

CONCLUSIONS

This study demonstrated the long-term safety and tolerability of dapagliflozin added to insulin therapy in Japanese patients with inadequately controlled T1DM.

Safety of SGLT2 Inhibitors in Patients with Diabetes Mellitus

BACKGROUND

Recently, Food and Drug Administration (FDA) has approved sodium/ glucose co-transporter 2 (SGLT2) inhibitors for the treatment of diabetes mellitus. However, regarding adverse drug reactions (ADRs) of SGLT2 inhibitors in large group of population, very less information is available. Thus, we have tried to find out the risk profile of SGLT2 inhibitors.

MATERIALS AND METHODS

A total of 1,042 studies have been published from Nov. 2012-Nov. 2017 regarding SGLT2 inhibitors. After inclusion and exclusion criteria, 27 studies have been selected for the analysis of risk.

RESULTS AND DISCUSSION

The emerging evidence indicates various adverse drug reactions such as foot and toe amputation, cancer, diabetic ketoacidosis, bone fracture risk and urinary as well as mycotic genital infection. The causality assessment has shown a correlation between SGLT2 inhibitors and diabetic ketoacidosis and urinary tract infection.

CONCLUSION

In conclusion, Marketing Authorization Holder (MAH) and Regulatory Authorities (RA) should monitor various adverse drug reactions such as diabetic ketoacidosis and urinary tract infection with the use of SGLT2 inhibitor.

Renal Benefits of SGLT 2 Inhibitors and GLP-1 Receptor Agonists: Evidence Supporting a Paradigm Shift in the Medical Management of Type 2 Diabetes

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.

Sodium glucose cotransporter 2 inhibitors and risk of genital mycotic and urinary tract infection: A population-based study of older women and men with diabetes

AIMS

The objective of the study was to quantify the association between SGLT2 inhibitors and genital mycotic infection and between SGLT2 inhibitors and urinary tract infection (UTI) within 30 days of drug initiation among older women and men.

MATERIALS AND METHODS

This was a retrospective cohort study using linked administrative databases of women and men with diabetes, aged 66 years or older, in Ontario, Canada. We compared the incidence of genital mycotic infection or UTI within 30 days between new users of an SGLT2 inhibitor and of a dipeptidyl-peptidase-4 (DPP4) inhibitor.

RESULTS

We identified 21 444 incident users of SGLT2 inhibitor and 22 463 incident users of DPP4 inhibitor. Among SGLT2 inhibitor users, there were 8848 (41%) women and the mean age at index was 71.8 ± 5 (SD) years. After adjusting for propensity score, age, sex and recent UTI, there was a 2.47-fold increased risk of genital mycotic infection with incident use of SGLT2 inhibitors (adjusted hazard ratio (HR), 2.47; 95% confidence interval (CI), 2.08-2.92; P < 0.001) within 30 days compared to incident use of DPP4 inhibitors. For UTI, the adjusted HR was 0.89 (95% CI, 0.78-1.00; P = 0.05).

CONCLUSIONS

Incident use of SGLT2 inhibitors among older women and men is associated with increased risk of genital mycotic infections within 30 days; there is no associated increased risk of UTI. These findings from a real-world setting provide evidence of the potential harms of SGLT2 inhibitors.

Differential pharmacology and clinical utility of dapagliflozin in type 2 diabetes

Dapagliflozin belongs in the family of sodium-glucose cotransporter 2 (SGLT2) inhibitors and acts by reducing glucose reabsorption in the proximal tubule. The aim of this review is to present the differential pharmacology and clinical utility of dapagliflozin. Dapagliflozin is orally administered, has a long half-life of 12.9 hours and (similar to empagliflozin) is a much weaker SGLT1 inhibitor compared with canagliflozin. Dapagliflozin significantly decreases glycated hemoglobin and fasting glucose levels in patients with type 2 diabetes mellitus (T2DM). The drug improves body weight, blood pressure, uric acid, triglycerides and high-density lipoprotein cholesterol. In the DECLARE-TIMI 58 trial, a large trial of 17,160 T2DM patients with established cardiovascular disease (CVD) or without established CVD but with multiple risk factors, dapagliflozin compared with placebo resulted in a significantly lower rate of the composite outcome of CVD death or hospitalization for heart failure (HHF); this effect was mainly due to a lower rate of HHF in the dapagliflozin group (HR: 0.73; 95%CI: 0.61–0.88), whereas no difference was observed in the rate of CVD death (HR: 0.98; 95%CI: 0.82–1.17). Moreover, dapagliflozin was noninferior to placebo with respect to major adverse CVD events. Dapagliflozin exerts beneficial effects on albuminuria. Additionally, in the DECLARE-TIMI 58 trial it significantly reduced the composite renal endpoint (40% decrease in glomerular filtration rate, end stage renal disease, or renal death) in both patients with established CVD and patients with multiple risk factors (overall HR: 0.53; 95%CI: 0.43–0.66). However dapagliflozin, like the other SGLT2 inhibitors, is associated with an increased risk of genital and urinary tract infections (usually mild mycotic infections) and acute kidney injury in cases of reduced extracellular volume. Dapagliflozin is a useful antidiabetic treatment which also exerts beneficial effects in the management of heart failure and diabetic kidney disease.

An update on the safety of SGLT2 inhibitors

INTRODUCTION

Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are recommended after metformin for a large spectrum of patients with type 2 diabetes, because of a favorable benefit/risk profile despite a variety of adverse events.

AREAS COVERED

This narrative review discusses the safety profile of SGLT2is: initial concerns (cardiovascular safety, acute renal failure, hypoglycemia, urinary and genital infections, volume depletion, bladder cancer), further concerns (euglycemic ketoacidosis, bone fractures) and more recent concerns (lower limb amputation, Fournier's gangrene).

EXPERT OPINION

Overall, the safety profile of SGLT2is is good. The only increased adverse event that was consistently reported in clinical trials and observational studies is genital mycotic infections, with only a borderline increase in urinary tract infections. Among clinical trials, only the CANVAS program reported an unexpected increase in bone fractures and peripheral amputations. A variety of rare adverse events have been described as case reports, including ketoacidosis, amputations and Fournier gangrene, which led to specific warnings by regulatory agencies. Identifying predisposing patient's characteristics and/or precipitating clinical conditions would help prevent the most severe complications. These adverse events should not mask the overall cardiovascular and renal benefit of SGLT2is, especially in patients with type 2 diabetes at high cardiovascular risk.

The effect of dapagliflozin on glycaemic control and other cardiovascular disease risk factors in type 2 diabetes mellitus: a real-world observational study

AIMS/HYPOTHESIS

Dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, is indicated for improving glycaemic control in type 2 diabetes mellitus. Whether its effects on HbA_1c and other variables, including safety outcomes, in clinical trials are obtained in real-world practice needs to be established.

METHODS

We used data from the comprehensive national diabetes register, the Scottish Care Information-Diabetes (SCI-Diabetes) collaboration database, available from 2004 to mid-2016. Data within this database were linked to mortality data from the General Registrar, available from the Information Services Division (ISD) of the National Health Service in Scotland. We calculated crude within-person differences between pre- and post-drug-initiation values of HbA_1c, BMI, body weight, systolic blood pressure (SBP) and eGFR. We used mixed-effects regression models to adjust for within-person time trajectories in these measures. For completeness, we evaluated safety outcomes, cardiovascular disease events, lower-limb amputation and diabetic ketoacidosis, focusing on cumulative exposure effects, using Cox proportional hazard models, though power to detect such effects was limited.

RESULTS

Among 8566 people exposed to dapagliflozin over a median of 210 days the crude within-person change in HbA_1c was -10.41 mmol/mol (-0.95%) after 3 months' exposure. The crude change after 12 months was -12.99 mmol/mol (-1.19%) but considering the expected rise over time in HbA_1c gave a dapagliflozin-exposure-effect estimate of -15.14 mmol/mol (95% CI -15.87, -14.41) (-1.39% [95% CI -1.45, -1.32]) at 12 months that was maintained thereafter. A drop in SBP of -4.32 mmHg (95% CI -4.84, -3.79) on exposure within the first 3 months was also maintained thereafter. Reductions in BMI and body weight stabilised by 6 months at -0.82 kg/m² (95% CI -0.87, -0.77) and -2.20 kg (95% CI -2.34, -2.06) and were maintained thereafter. eGFR declined initially by -1.81 ml min^-1 [1.73 m]^-2 (95% CI -2.10, -1.52) at 3 months but varied thereafter. There were no significant effects of cumulative drug exposure on safety outcomes.

CONCLUSIONS/INTERPRETATION

Dapagliflozin exposure was associated with reductions in HbA_1c, SBP, body weight and BMI that were at least as large as in clinical trials. Dapagliflozin also prevented the expected rise in HbA_1c and SBP over the period of study.

The renoprotective effects of sodium-glucose cotransporter 2 inhibitors versus placebo in patients with type 2 diabetes with or without prevalent kidney disease: A systematic review and meta-analysis

AIMS

We undertook a systematic review and meta-analysis to assess the efficacy and safety of sodium-glucose cotransporter 2 inhibitors (SGLT2is) concerning kidney outcomes in patients with type 2 diabetes mellitus (T2DM), with or without prevalent kidney disease.

MATERIALS AND METHODS

PubMed, Web of science, Embase and the Cochrane Library were systematically searched for randomized controlled trials (RCTs) to assess the efficacy and safety of treatment with SGLT2is versus placebo in patients with T2DM. The weighted mean difference (WMD) and its 95% confidence interval (CI) were applied for continuous variables, and the risk ratio (RR) and corresponding 95% CI were used for dichotomous outcomes. Patients were categorized according to whether the baseline mean estimated glomerular filtration rate (eGFR) was less or was more than 60 mL/min/1.73 m² .

RESULTS

A total of 25 eligible studies with 43 721 participants were included. There was an initial and small decrease in eGFR during the early treatment period (WMD, -4.63; 95% CI, -6.08 to -3.19 mL/min/1.73 m² ), which was noted at 1-6 weeks and gradually narrowed over time, with a decline in protection from eGFR in the long term (WMD, 3.82; 95% CI, 2.80-4.85 mL/min/1.73 m² ). SGLT2is significantly delayed albuminuria progression (RR, 0.71; 95% CI, 0.66-0.76), promoted albuminuria regression (RR,1.71; 95% CI, 1.54-1.90), improved the composite of ≥40% decrease in eGFR, in the need for renal-replacement and in death from renal causes (RR, 0.57; 95% CI, 0.49-0.66), and reduced all-cause mortality (RR, 0.84; 95% CI, 0.75-0.94). At the same time, they significantly increased the risk of genital infection (RR, 3.43; 95% CI, 2.87-4.10) vs placebo in patients with T2DM. Meta-regression analyses showed that eGFR-preservation effects were not significantly associated with basic patient characteristics (age, BMI, HbA1c, eGFR level), but were influenced by drug administration (treatment duration, type, dosage of SGLT2is). Subgroup analyses showed that the relative effects on renal outcomes of SGLT2is vs placebo were similar across eGFR subgroups (P heterogeneity >0.05).

CONCLUSIONS

SGLT2is slowed eGFR decline, lowered albuminuria progression, improved adverse renal endpoints and reduced all-cause mortality, but increased risk of genital infections vs placebo in patients with T2DM. The indication of consistent renal benefits across categories of baseline eGFR levels may allow additional individuals to benefit from SGLT2is therapy.

Sustained 52-week efficacy and safety of triple therapy with dapagliflozin plus saxagliptin versus dual therapy with sitagliptin added to metformin in patients with uncontrolled type 2 diabetes

AIMS

To compare the efficacy and safety of an intensification strategy of early triple combination therapy with dapagliflozin (DAPA) plus saxagliptin (SAXA) to a dual therapy strategy with sitagliptin (SITA) in patients with type 2 diabetes who are inadequately controlled with metformin (MET) monotherapy.

MATERIALS AND METHODS

This multinational, active-controlled, parallel-group phase 3b trial randomized 461 patients, at least 18 years of age, with glycated haemoglobin (HbA1c) of 8%-10.5% (64-91 mmol/mol), to either DAPA plus SAXA or SITA, added to MET, for a 26-week double-blind treatment period and an extension of a 26-week blinded treatment period.

RESULTS

Mean (± SD) baseline HbA1c was 8.8% ± 0.9% (73.0 ± 9.3 mmol/mol). DAPA plus SAXA (n = 232) provided a greater reduction from baseline in HbA1c at Weeks 26 and 52 compared with SITA (n = 229) (adjusted mean ± SE change, Week 26: -1.41 ± 0.07% vs -1.07 ± 0.07% [-15.4 ± 0.8 mmol/mol vs 11.7 ± 0.8 mmol/mol]; P = 0.0008; Week 52: -1.29 ± 0.08% vs -0.81 ± 0.09% [14.1 ± 0.9 mmol/mol vs 8.9 ± 1.0 mmol/mol]). The between-group difference in adjusted mean (95% CI) change from baseline in HbA1c increased from -0.34 (-0.54, -0.14) at Week 26 to -0.48 (-0.71, -0.25) at Week 52. DAPA plus SAXA was generally well tolerated and the incidence of adverse events was similar in both treatment arms.

CONCLUSIONS

Early intensification to triple therapy with DAPA plus SAXA results in better, more durable glycaemic control than addition of SITA only (dual therapy) in patients with high HbA1c levels who are uncontrolled with MET monotherapy.

Improvement in Glycemic and Lipid Profiles in Type 2 Diabetics with a 90-Day Ketogenic Diet

Because low-carbohydrate diets are effective strategies to improve insulin resistance, the hallmark of type 2 diabetes, the purpose of reporting these clinical cases was to reveal the meaningful changes observed in 90 days of low-carbohydrate (LC) ketogenic dietary intervention in female type 2 diabetics aged 18-45. Eleven women (BMI 36.3 kg/m²) who were recently diagnosed with type 2 diabetes based on HbA1c over 6.5% (8.9%) volunteered to participate in an intensive dietary intervention to limit dietary carbohydrates to under 30 grams daily for 90 days. The main outcome was to determine the degree of change in HbA1c, while secondary outcomes included body weight, blood pressure, and blood lipids. The volunteers lost significant weight (85.7 ± 3.2 kg to 76.7 ± 2.8 kg) and lowered systolic (134.0 ± 1.6 to 123.3 ± 1.1 mmHg) and diastolic (89.9 ± 1.3 to 82.6 ± 1.0 mmHg) blood pressure. HbA1c dropped to 5.6%. Most blood lipids were significantly altered, including HDL cholesterol (43.1 ± 4.4 to 52.3 ± 3.3 mg/dl), triglycerides (177.0 ± 19.8 to 92.1 ± 8.7 mg/dl), and the TG : HDL ratio (4.7 ± 0.8 to 1.9 ± 0.2). LDL cholesterol was not significantly different. AST and ALT, plasma markers of liver health, were reported for eight patients and revealed no significant changes. These findings indicate that a short-term intervention emphasizing protein and fat at the expense of dietary carbohydrate functionally reversed the diabetes diagnosis, as defined by HbA1c. Furthermore, the intervention lowered body weight and blood pressure, while eliciting favorable changes in blood lipids.

Sodium Glucose Co-transporter-2 Inhibitor: Benefits beyond Glycemic Control

Type 2 diabetes mellitus (T2DM) is a family of metabolic disorders characterized by hyperglycemia as a consequence of abnormalities in insulin secretion and insulin sensitivity. It affects hundreds of millions of people worldwide and leads to increased morbidity, compromised quality of life, higher mortality sodium glucose co-transporter 2 (SGLT2) inhibitors, a new class of oral antidiabetic drugs, have garnered considerable attention in the recent past and are considered potential first-line candidates for the management of T2DM. This review outlines the evidence-based therapeutic efficacy, safety, limitations, and advantages of SGLT2 inhibitors in the management of T2DM. SGLT2 inhibitors work by preventing the kidneys from reabsorbing glucose back into the blood, leading to increase in excretion of glucose through urine, thereby lowering hyperglycemia. Treatment with SGLT2 inhibitors improves A1C levels, reduces blood pressure and body weight, and is overall well tolerated by patients with T2DM. However, additional data on long-term cardiovascular safety are still needed. Characteristic adverse events include mild genital - urinary tract infection more commonly seen in women than in men, but serious infection is uncommon. Their use should be exercised with extra caution in patients suffering from renal impairment. Further, advancing to dual/triple combinational therapies with SGLT2 inhibitors and existing oral antidiabetic options may prove to be a breakthrough in the management of T2DM.

Infection of urinary tract in menopausal women

Urinary infections are, by frequency, in the second place, immediately behind respiratory infections. The prevalence of urinary tract infections is generally increasing. UTI (urinary tract infections) is more common in women and very young people. The rates of occurrence generally reflect predisposing factors such as congenital anomalies in childhood, the onset of sexual activity, especially in women, and, of course, postmenopausal changes in older women. It is assumed that 50-60% of women can expect an episode of urinary infection during their lifetime. In postmenopausal women, there is a deficit in estrogen. It is one of the important factors that indirectly protects the vaginal mucous membranes as well as the uroepitel from infection. Bacteria from the digestive tract colonize the skin of the perineum, then the vulva, the vagina and the outer opening of the urethra. Normal vaginal flora (lactobacilli) protects the vagina from colonization by fecal bacteria because it lowers pH and creates unfavorable conditions for survival of bacteria.

SGLT-2 Inhibition: Novel Therapeutics for Reno-and Cardioprotection in Diabetes Mellitus

BACKGROUND

The sodium glucose co-transporter 2 (SGLT2) is primarily located within S1 of the renal proximal tubule being responsible for approximately 90% of glucose re-uptake in the kidney. Inhibition of SGLT2 is an exciting new pharmacological approach for the reduction of blood glucose in type 2 diabetic patients via inhibition of tubular glucose reabsorption. In addition to lowering glucose, this group of drugs has shown significant cardiovascular and renal protective effects.

CONCLUSION

This review aims to outline the current state of preclinical research and clinical trials for different SGLT2 inhibitors and outline some of the proposed mechanisms of action, including possible effects on sympathetic nerve activity, which may contribute to the unexpected beneficial cardiovascular and reno-protective effects of this class of compounds.
