RESUMO
BACKGROUND: Hypertriglyceridemia is increasingly considered a residual risk of cardiovascular disease in patients with chronic kidney disease (CKD). Pemafibrate-a novel selective peroxisome proliferator-activated receptor alpha modulator and a new treatment for hypertriglyceridemia in CKD patients-is reported to have fewer side effects in CKD patients than other fibrates. Appropriate control of hypertriglyceridemia can be expected to improve renal prognosis. However, data on the renal protective effect of pemafibrate are limited. This study aims to evaluate the effectiveness of pemafibrate on urinary protein excretion in CKD patients. METHODS: The Pemafibrate, open-label, Randomized cOntrolled study to evaluate the renal protective eFfect In hyperTriglyceridemia patients with Chronic Kidney Disease (PROFIT-CKD) study is an investigator-initiated, multi-center, open-label, parallel-group, randomized controlled trial. Participants are outpatients with hypertriglyceridemia aged 20 years and over, who have received the care of a nephrologist or a diabetologist for more than 3 months. Inclusion criteria include the following: proteinuria (urine protein/creatinine ratio of ≥ 0.15 g/gCr) within three months before allocation, and hypertriglyceridemia (triglycerides ≥ 150 mg/dL and < 1,000 mg/dL) at allocation. In the treatment group, pemafibrate is added to conventional treatment, while conventional treatment is continued with no additional treatment in the control group. Target patient enrollment is 140 patients. The primary endpoint is the change from baseline in the logarithmic urine protein/creatinine ratio at 12 months after study start. CONCLUSION: This study will provide new findings on the renal protective effect of pemafibrate in CKD patients. CLINICAL TRIAL REGISTRATION: This clinical trial was registered at the University Hospital Medical Information Network (UMIN) Center (UMIN-CTR: UMIN000042284).

BACKGROUND: Epidemiological data regarding diabetic kidney disease are accumulated insufficiently in Japan. We prospectively investigated the incidence of end-stage renal disease (ESRD) and risk factors for progression of renal dysfunction in Japanese patients with type 2 diabetes. METHODS: 4904 participants with type 2 diabetes (mean age 65 years, mean estimated glomerular filtration rate (eGFR) 75 mL/min/1.73 m2, proportion of eGFR < 60 mL/min/1.73 m2 21%) were investigated for the progression to ESRD requiring dialysis in multicenter outpatients registry for 5 years. Risk factors for progression of renal dysfunction (≥ 30% decline in eGFR from the baseline and annual eGFR decline rates) were evaluated. RESULTS: The incidence rates of ESRD and all-cause mortality were 4.1/1000 person-years and 12.3/1000 person-years, respectively, and increased according to stages of chronic kidney disease (eGFR < 30 mL/min/1.73 m2, incidence of ESRD 176.6/1000 person-years, all-cause mortality 57.4/1000 person-years). Incidence of ≥ 30% decline in eGFR from the baseline was 16.4% at 5 years, and the mean annual decline rate was -1.84 mL/min/1.73 m2/year. The progression of renal dysfunction was significantly associated with older age, poor glycemic control, blood pressure, albuminuria, eGFR, previous cardiovascular disease, lifestyle factors (body mass index, reduced intake of dietary fiber, increased intake of sodium, no regular exercise), and depressive symptoms. CONCLUSIONS: This prospective study has emphasized the importance of multifactorial interventions on risk factors to suppress the high incidence of ESRD in Japanese patients with type 2 diabetes.

RATIONALE & OBJECTIVE: Changes in urinary albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) have been used separately as alternative kidney disease outcomes in randomized trials. We tested the hypothesis that combined changes in UACR and eGFR predict advanced kidney disease better than either alone. STUDY DESIGN: Observational cohort study. SETTING & PARTICIPANTS: 91,319 primary care patients assembled from the Clinical Practice Research Datalink in the United Kingdom between 2000 and 2015. EXPOSURES: Changes in UACR and eGFR (categorized as ≥30% increase, stable, or ≥30% decrease), alone and in combination, over a 3-year period. OUTCOMES: The primary outcome was advanced CKD (sustained eGFR <30 mL/min/1.73 m2); secondary outcomes included kidney failure, cardiovascular disease, and all-cause mortality. ANALYTICAL APPROACH: Multivariable Cox regression with bias from missing values assessed using multiple imputation; discrimination statistics compared across exposure groups. RESULTS: 91,319 individuals were studied, with a mean eGFR of 72.6 mL/min/1.73 m2 and median UACR of 9.7 mg/g; 70,957 (77.7%) had diabetes. During a median follow-up of 2.9 years, 2,541 people progressed to advanced CKD. Compared with stable values, hazard ratios for a ≥30% increase in UACR and ≥30% decrease in eGFR were 1.78 (95% CI, 1.59-1.98) and 7.53 (95% CI, 6.70-8.45), respectively, for the outcome of advanced CKD. Compared with stable values of both, the hazard ratio for the combination of an increase in UACR and a decrease in eGFR was 15.15 (95% CI, 12.43-18.46) for the outcome of advanced CKD. The combination of changes in UACR and eGFR predicted kidney outcomes better than either alone. LIMITATIONS: Selection bias, relatively small proportion of individuals without diabetes, and very few kidney failure events. CONCLUSIONS: In a large-scale general population, the combination of an increase in UACR and a decrease in eGFR was strongly associated with the risk of advanced CKD. Further assessment of combined changes in UACR and eGFR as an alternative outcome for kidney failure in trials of CKD progression is warranted.

RATIONALE & OBJECTIVE: Canagliflozin reduces the risk for cardiovascular and kidney outcomes in type 2 diabetes. This study aimed to assess the relative and absolute effects of canagliflozin on clinical outcomes across different KDIGO (Kidney Disease: Improving Global Outcomes) risk categories based on estimated glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio. STUDY DESIGN: Post hoc analysis of the CANagliflozin cardioVascular Assessment Study (CANVAS) Program. SETTINGS & PARTICIPANTS: The CANVAS Program randomly assigned 10,142 participants with type 2 diabetes at high cardiovascular risk and with eGFR≥30mL/min/1.73m2 to treatment with canagliflozin or placebo. INTERVENTION(S): Canagliflozin or matching placebo. OUTCOMES: The primary outcome was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke, with a set of other cardiovascular and kidney prespecified outcomes. RESULTS: Of 10,142 participants, 10,031 (98.9%) had available baseline eGFR and urinary albumin-creatinine ratio data. The proportion of participants in low-, moderate-, high-, and very high-risk KDIGO categories was 58.6%, 25.8%, 10.6%, and 5.0%, respectively. The relative effect of canagliflozin on the primary outcome (HR, 0.86; 95% CI, 0.75-0.97) was consistent across KDIGO risk categories (P trend=0.2), with similar results for other cardiovascular and kidney outcomes. Absolute reductions in the primary outcome were greater within higher KDIGO risk categories (P trend=0.03) with a similar pattern of effect for the composite of cardiovascular death or hospitalization for heart failure (P trend=0.06) and for chronic eGFR slope (P trend = 0.04). LIMITATIONS: Predominantly a low kidney risk population, relatively few participants in higher KDIGO risk categories, and exclusion of individuals with eGFR<30mL/min/1.73m2. CONCLUSIONS: Although the relative effects of canagliflozin are similar across KDIGO risk categories, absolute risk reductions are likely greater for individuals at higher KDIGO risk. The KDIGO classification system may be able to identify individuals who might derive greater benefits for end-organ protection from treatment with canagliflozin. FUNDING: This post hoc analysis was not specifically funded. The original CANVAS Program trials were funded by Janssen Research & Development, LLC and were conducted as a collaboration between the funder, an academic steering committee, and an academic research organization, George Clinical. TRIAL REGISTRATION: The original trials of the CANVAS Program were registered at ClinicalTrials.gov with study numbers NCT01032629 and NCT01989754.

AIMS: For relatively old patients with diabetes, current guidelines recommend adjustment of glycaemic goals based on patients' cognitive function, or coexisting chronic illnesses. However, the evidence which supports the efficacy and safety of intensive glucose lowering in older patients with diabetes is scarce. The objective of the present study was to compare the efficacy and safety of intensive glucose lowering in patients with type 2 diabetes stratified by age (<65 and ≥ 65 years), and examine whether the effects differ according to patients' characteristics in the older patient group. MATERIALS AND METHODS: The effects of intensive glucose lowering (to a target glycated haemoglobin [HbA1c] concentration of ≤48 mmol/mol [6.5%]) on major clinical outcomes were evaluated by Cox regression models according to subgroups defined by baseline age of <65 or ≥ 65 years in the ADVANCE trial (n = 11 140). RESULTS: Over a median follow-up of 5 years, intensive glucose lowering significantly decreased the risk of the composite of major macrovascular and microvascular events (hazard ratio 0.90, 95% confidence interval 0.82-0.98), with no heterogeneity in the effects across age subgroups (p for heterogeneity = 0.44). Relative effects on all-cause death, cardiovascular death, and components of major vascular events were also similar (P for heterogeneity ≥0.06), except for severe hypoglycaemia, which was of greater risk for patients aged <65 years. Absolute benefits and harms were broadly consistent across subgroups. Among patients aged ≥65 years, randomized treatment effects did not differ significantly across different levels of cognitive function or coexisting chronic illnesses. CONCLUSIONS: Our results suggest that an intensive glycaemic control strategy to reduce HbA1c to 48 mmol/mol (6.5%) provided broadly similar benefits and harms and may be recommended for older, as well as younger, patients.

BACKGROUND: Constipation was shown to be associated with higher risk of end-stage kidney disease or incident chronic kidney disease, although evidence in diabetic patients is lacking. The objective of the present study was to examine the association between constipation and diabetic kidney disease (DKD). METHODS: In total, 4826 Japanese outpatients with type 2 diabetes were classified according to presence or absence of constipation (defecation frequency < 3 times/week and/or taking laxative medication). DKD was defined as presence of decreased estimated glomerular filtration rate (eGFR < 60 ml/min/1.73 m2), and/or albuminuria (urinary albumin-to-creatinine ratio ≥ 30 mg/g). Odds ratios for the presence of DKD were computed by a logistic regression model. RESULTS: Compared with participants without constipation, the age- and sex-adjusted odds ratio for presence of DKD was 1.58 (95% confidence interval 1.38-1.82) for those with constipation. This association persisted following adjustment for potential confounding factors. Decreased defecation frequency and laxative use were also significantly associated with higher prevalence of DKD. Overall, these findings were identical even when decreased eGFR and albuminuria were separately analyzed. CONCLUSIONS: Constipation was associated with higher likelihood of DKD in patients with diabetes, suggesting the importance of clinical assessment of constipation to identify patients at high risk of progression of kidney disease.

BACKGROUND: Traditionally, clinical trials evaluating effects of a new therapy with creatinine-based renal end points use doubling of serum creatinine (equivalent to a 57% eGFR reduction), requiring large sample sizes. METHODS: To assess whether eGFR declines <57% could detect canagliflozin's effects on renal outcomes, we conducted a post hoc study comparing effects of canagliflozin versus placebo on composite renal outcomes using sustained 57%, 50%, 40%, or 30% eGFR reductions in conjunction with ESKD and renal death. Because canagliflozin causes an acute reversible hemodynamic decline in eGFR, we made estimates using all eGFR values as well as estimates that excluded early measures of eGFR influenced by the acute hemodynamic effect. RESULTS: Among the 10,142 participants, 93 (0.9%), 161 (1.6%), 352 (3.5%), and 800 (7.9%) participants recorded renal outcomes on the basis of 57%, 50%, 40%, or 30% eGFR reduction, respectively, during a mean follow-up of 188 weeks. Compared with a 57% eGFR reduction (risk ratio [RR], 0.51; 95% confidence interval [95% CI], 0.34 to 0.77), the effect sizes were progressively attenuated when using 50% (RR, 0.61; 95% CI, 0.45 to 0.83), 40% (RR, 0.70; 95% CI, 0.57 to 0.86), or 30% (RR, 0.81; 95% CI, 0.71 to 0.93) eGFR reductions. In analyses that controlled for the acute hemodynamic fall in eGFR, effect sizes were comparable, regardless of whether a 57%, 50%, 40%, or 30% eGFR reduction was used. Estimated sample sizes for studies on the basis of lesser eGFR reductions were much reduced by controlling for this early hemodynamic effect. CONCLUSIONS: Declines in eGFR <57% may provide robust estimates of canagliflozin's effects on renal outcomes if the analysis controls for the drug's acute hemodynamic effect.

AIMS: Sodium glucose co-transporter 2 (SGLT2) inhibitors reduce several cardiovascular risk factors, including plasma glucose, blood pressure, albuminuria and body weight. Long-term treatment lowers risks of cardiovascular and renal events. The objective of this post hoc analysis was to determine the effects of canagliflozin treatment versus placebo on clinical outcomes in relation to body mass index (BMI). MATERIALS AND METHODS: The CANVAS Program randomized 10 142 participants with type 2 diabetes to canagliflozin or placebo. These analyses tested the consistency of canagliflozin treatment effects across BMI levels for cardiovascular, renal, safety and body weight outcomes in three groups defined by baseline BMI: <25, 25-<30 and ≥30 kg/m2 . RESULTS: In total, 10 128 participants with baseline BMI measurements were included. There were 966 participants with BMI <25 kg/m2 , 3153 with BMI 25-<30 kg/m2 and 6009 with BMI ≥30 kg/m2 . Mean percent body weight reduction with canagliflozin compared with placebo was greater at 12 months [-2.77% (95% confidence interval (CI): -2.95, -2.59)] than at 3 months [-1.72% (95% CI: -1.83, -1.62)]. The hazard ratios (HRs) for canagliflozin compared with placebo control for the composite outcome of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke were 1.03 (95% CI: 0.66, 1.59) in participants with BMI <25 kg/m2 , 0.97 (0.76, 1.23) with BMI 25-<30 kg/m2 and 0.79 (0.67, 0.93) with BMI ≥30 kg/m2 (P for heterogeneity = 0.55). The effects of canagliflozin on each component of the composite were also similar across BMI subgroups, as were effects on heart failure and renal outcomes (P for heterogeneity ≥0.19). The effects on safety outcomes were also broadly similar. CONCLUSIONS: Canagliflozin improved cardiovascular and renal outcomes consistently across patients with a broad range of BMI levels.

AIM: To examine possible sex differences in the excess risk of myocardial infarction (MI) consequent to a range of conventional risk factors in a large-scale international cohort of patients with diabetes, and to quantify these potential differences both on the relative and absolute scales. MATERIALS AND METHODS: Eleven thousand and sixty-five participants (42% women) with type 2 diabetes in the ADVANCE trial and its post-trial follow-up study, ADVANCE-ON, were included. Cox regression models were used to estimate hazard ratios (HRs) for associations between risk factors and MI (fatal and non-fatal) by sex, and the women-to-men ratio of HRs (RHR). RESULTS: Over a median of 9.6 years of follow-up, 719 patients experienced MI. Smoking status, smoking intensity, higher systolic blood pressure (SBP), HbA1c, total and LDL cholesterol, duration of diabetes, triglycerides, body mass index (BMI) and lower HDL cholesterol were associated with an increased risk of MI in both sexes. Furthermore, some variables were associated with a greater relative risk of MI in women than men: RHRs were 1.75 (95% CI: 1.05-2.91) for current smoking, 1.53 (1.00-2.32) for former smoking, 1.18 (1.02-1.37) for SBP, and 1.13 (95% CI, 1.003-1.26) for duration of diabetes. Although incidence rates of MI were higher in men (9.3 per 1000 person-years) compared with women (5.8 per 1000 person-years), rate differences associated with risk factors were greater in women than men, except for HDL cholesterol and BMI. CONCLUSIONS: In patients with type 2 diabetes, smoking, higher SBP and longer duration of diabetes had a greater relative and absolute effect in women than men, highlighting the importance of routine sex-specific approaches and early interventions in women with diabetes.

To assess the effects of intensive glucose control on the risk of major clinical outcomes according to estimated glomerular filtration rate (eGFR) levels in people with type 2 diabetes. Of 11 140 ADVANCE trial participants, 11 096 with baseline eGFR measurements were included, and classified into three eGFR groups: ≥90 mL/min/1.73 m2 ; 60 to 89 mL/min/1.73 m2 ; and < 60 mL/min/1.73 m2 . Relative risk reduction of randomized intensive glucose control with regard to the composite outcome of major macro- and microvascular events, all-cause death and cardiovascular death did not significantly vary by eGFR level (P for heterogeneity ≥0.49). The risk of severe hypoglycaemia increased with intensive glucose control; however, this risk did not vary across eGFR groups (P for heterogeneity = 0.83). The risk-benefit profile of intensive glucose control in patients with type 2 diabetes and impaired kidney function appears similar to that observed in those with preserved kidney function.

BACKGROUND: If SGLT2 inhibitors protect the kidneys by reducing albuminuria as hypothesized, people with type 2 diabetes mellitus (T2DM) with higher albuminuria should benefit more. METHODS: We conducted a post-hoc analysis of data from the CANagliflozin cardioVascular Assessment Study (CANVAS) Program, which randomized 10,142 participants with T2DM and high cardiovascular risk to canagliflozin or placebo. We assessed effects of canagliflozin on renal, cardiovascular, and safety outcomes by baseline albuminuria. The trial included 2266 participants (22.3%) with moderately increased albuminuria (urinary albumin/creatinine ratio [UACR] 30-300 mg/g) and 760 (7.5%) with severely increased albuminuria (UACR >300 mg/g) at baseline. RESULTS: Canagliflozin lowered albuminuria with greater proportional reductions in those with moderately and severely increased albuminuria (P heterogeneity<0.001). After week 13, canagliflozin slowed the annual loss of kidney function across albuminuria subgroups, with greater absolute reductions in participants with severely increased albuminuria (placebo-subtracted difference 3.01 ml/min per 1.73 m2 per year; P heterogeneity<0.001). Heterogeneity for the renal composite outcome of 40% reduction in eGFR, ESKD, or renal-related death was driven by lesser effects in participants with moderately increased albuminuria (P heterogeneity=0.03), but no effect modification was observed when albuminuria was fitted as a continuous variable (P heterogeneity=0.94). Cardiovascular and safety outcomes were mostly consistent across albuminuria levels including increased risks for amputation across albuminuria subgroups (P heterogeneity=0.66). Greater absolute risk reductions in the renal composite outcome were observed in participants with severely increased albuminuria (P heterogeneity=0.004). CONCLUSIONS: The proportional effects of canagliflozin on renal and cardiovascular outcomes are mostly consistent across patients with different levels of albuminuria, but absolute benefits are greatest among those with severely increased albuminuria.

AIMS/HYPOTHESIS: The prevalence of diabetes and heart failure is increasing, and diabetes has been associated with an increased risk of heart failure. However, whether diabetes confers the same excess risk of heart failure in women and men is unknown. The aim of this study was to conduct a comprehensive systematic review with meta-analysis of possible sex differences in the excess risk of heart failure consequent to diabetes. Our null hypothesis was that there is no such sex difference. METHODS: A systematic search was conducted in PubMed for population-based cohort studies published between January 1966 and November 2018. Studies were selected if they reported sex-specific estimates of RRs for heart failure associated with diabetes, and its associated variability, which were adjusted at least for age. Random-effects meta-analyses with inverse variance weighting were used to obtain pooled sex-specific RRs and women-to-men ratio of RRs (RRRs) for heart failure associated with diabetes. RESULTS: Data from 47 cohorts, involving 12,142,998 individuals and 253,260 heart failure events, were included. The pooled multiple-adjusted RR for heart failure associated with type 1 diabetes was 5.15 (95% CI 3.43, 7.74) in women and 3.47 (2.57, 4.69) in men, leading to an RRR of 1.47 (1.44, 1.90). Corresponding pooled RRs for heart failure associated with type 2 diabetes were 1.95 (1.70, 2.22) in women and 1.74 (1.55, 1.95) in men, with a pooled RRR of 1.09 (1.05, 1.13). CONCLUSIONS/INTERPRETATION: The excess risk of heart failure associated with diabetes is significantly greater in women with diabetes than in men with diabetes. PROSPERO registration: CRD42019135246.

AIMS/HYPOTHESIS: Some studies have reported that annual change in eGFR (eGFR slope) is associated with the future risk of end-stage kidney disease, cardiovascular disease and death in general or chronic kidney disease cohorts. However, the benefits of using eGFR slopes for prediction of major clinical outcomes in diabetes are unclear. METHODS: We used data from the Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation (ADVANCE) trial and the ADVANCE Post-Trial Observational Study (ADVANCE-ON). After excluding the first 4 months during which an acute fall in eGFR was induced by the initiation of an ACE inhibitor and diuretic combination agent, eGFR slopes were estimated by linear mixed models, using three measurements of eGFR at 4, 12 and 24 months after randomisation over 20 months, and categorised according to quartiles. Cox regression models were used to evaluate adjusted HRs for the study's primary outcome, a composite of major renal events, major macrovascular events and all-cause mortality during the subsequent follow-up from 24 months after randomisation. RESULTS: A total of 8,879 participants (80%) were included in this cohort. The mean age was 65.6 years (SD 6.3), the mean eGFR was 75 ml min-1 (1.73 m)-2 (SD 17) and the median urinary albumin/creatinine ratio was 14 µg/mg (interquartile range 7-38). The mean eGFR slope was -0.63 ml min-1 (1.73 m)-2 year-1 (SD 1.75). Over a median follow-up of 7.6 years following the 20-month eGFR slope ascertainment period, 2,221 participants (25%) met the primary outcome. An annual substantial decrease in eGFR (lowest 25%, <-1.63 ml min-1 [1.73 m]-2 year-1) was significantly associated with the subsequent risk of the primary outcome (HR 1.30 [95% CI 1.17, 1.43]) compared with a stable change in eGFR (middle 50%, -1.63 to 0.33). An annual substantial increase in eGFR (highest 25%, >0.33) had no significant association with the risk of the primary outcome (HR 0.96 [95% CI 0.86, 1.07]). CONCLUSIONS/INTERPRETATION: Our study supports the utility of eGFR slope in type 2 diabetes as a surrogate endpoint for renal outcomes, as well as a prognostic factor for identifying individuals at high risk of cardiovascular disease and all-cause mortality.

BACKGROUND: Canagliflozin is approved for glucose lowering in type 2 diabetes and confers cardiovascular and renal benefits. We sought to assess whether it had benefits in people with chronic kidney disease, including those with an estimated glomerular filtration rate (eGFR) between 30 and 45 mL/min/1.73 m2 in whom the drug is not currently approved for use. METHODS: The CANVAS Program randomized 10 142 participants with type 2 diabetes and eGFR >30 mL/min/1.73 m2 to canagliflozin or placebo. The primary outcome was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke, with other cardiovascular, renal, and safety outcomes. This secondary analysis describes outcomes in participants with and without chronic kidney disease, defined as eGFR <60 and ≥60 mL/min/1.73 m2, and according to baseline kidney function (eGFR <45, 45 to <60, 60 to <90, and ≥90 mL/min/1.73 m2). RESULTS: At baseline, 2039 (20.1%) participants had an eGFR <60 mL/min/1.73 m2, 71.6% of whom had a history of cardiovascular disease. The effect of canagliflozin on the primary outcome was similar in people with chronic kidney disease (hazard ratio, 0.70; 95% CI, 0.55-0.90) and those with preserved kidney function (hazard ratio, 0.92; 95% CI, 0.79-1.07; P heterogeneity = 0.08). Relative effects on most cardiovascular and renal outcomes were similar across eGFR subgroups, with possible heterogeneity suggested only for the outcome of fatal/nonfatal stroke ( P heterogeneity = 0.01), as were results for almost all safety outcomes. CONCLUSIONS: The effects of canagliflozin on cardiovascular and renal outcomes were not modified by baseline level of kidney function in people with type 2 diabetes and a history or high risk of cardiovascular disease down to eGFR levels of 30 mL/min/1.73 m2. Reassessing current limitations on the use of canagliflozin in chronic kidney disease may allow additional individuals to benefit from this therapy.

AIM: The use of sodium glucose co-transporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) has been limited, primarily because glycaemic efficacy is dependent on kidney function. We performed a systematic review and meta-analysis to assess the efficacy and safety of SGLT2 inhibitors in patients with T2DM and CKD, defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 . MATERIALS AND METHODS: We searched MEDLINE, EMBASE and the Cochrane Library until 7 August 2018 and websites of the US, European and Japanese regulatory authorities until 27 July 2018 for data from randomized controlled trials of SGLT2 inhibitors that included reporting of effects on biomarkers, cardiovascular, renal or safety outcomes in individuals with T2DM and CKD. Random effects models and inverse variance weighting were used to calculate relative risks with 95% confidence intervals. RESULTS: Data were obtained from 27 studies with up to 7363 participants involved. In patients with T2DM and CKD, SGLT2 inhibitors lowered glycated haemoglobin (-0.29%; 95% CI, -0.39 to -0.19) as well as blood pressure, body weight and albuminuria. SGLT2 inhibition reduced the risk of cardiovascular death, nonfatal myocardial infarction or nonfatal stroke (RR, 0.81; 95% CI, 0.70-0.94) and heart failure (RR, 0.61; 95% CI, 0.48-0.78), without a clear effect on all-cause mortality (HR, 0.86; 95% CI, 0.73-1.01). These agents also attenuated the annual decline in eGFR slope (placebo-subtracted difference of 1.35 mL/1.73 m2 /y; 95% CI, 0.78-1.93) and reduced the risk of the composite renal outcome (HR, 0.71; 95% CI, 0.53-0.95). There was no evidence of additional risks with SGLT2 inhibition in CKD beyond those already known for the class, although heterogeneity was observed across individual agents for some safety outcomes. CONCLUSION: Currently available data suggest that, despite only modest reductions in glycated haemoglobin, SGLT2 inhibitors reduce the risk of cardiovascular and renal outcomes in patients with T2DM and CKD, without clear evidence of additional safety concerns.

AIMS/HYPOTHESIS: Diabetes has been shown to be a risk factor for some cancers. Whether diabetes confers the same excess risk of cancer, overall and by site, in women and men is unknown. METHODS: A systematic search was performed in PubMed for cohort studies published up to December 2016. Selected studies reported sex-specific relative risk (RR) estimates for the association between diabetes and cancer adjusted at least for age in both sexes. Random-effects meta-analyses with inverse-variance weighting were used to obtain pooled sex-specific RRs and women-to-men ratios of RRs (RRRs) for all-site and site-specific cancers. RESULTS: Data on all-site cancer events (incident or fatal only) were available from 121 cohorts (19,239,302 individuals; 1,082,592 events). The pooled adjusted RR for all-site cancer associated with diabetes was 1.27 (95% CI 1.21, 1.32) in women and 1.19 (1.13, 1.25) in men. Women with diabetes had ~6% greater risk compared with men with diabetes (the pooled RRR was 1.06, 95% CI 1.03, 1.09). Corresponding pooled RRRs were 1.10 (1.07, 1.13) for all-site cancer incidence and 1.03 (0.99, 1.06) for all-site cancer mortality. Diabetes also conferred a significantly greater RR in women than men for oral, stomach and kidney cancer, and for leukaemia, but a lower RR for liver cancer. CONCLUSIONS/INTERPRETATION: Diabetes is a risk factor for all-site cancer for both women and men, but the excess risk of cancer associated with diabetes is slightly greater for women than men. The direction and magnitude of sex differences varies by location of the cancer.

AIMS: Patients with type 2 diabetes have a high risk of cardiovascular disease (CVD). Central obesity has been particularly associated with this risk relationship. We aimed to evaluate waist to height ratio (WHtR) as a predictor of risk in such patients. METHODS: WHtR was evaluated as a predictor of the risk of CVD and mortality amongst 11 125 participants with type 2 diabetes in the ADVANCE and ADVANCE-ON studies, and was compared with body mass index (BMI), waist circumference and waist hip ratio (WHR). Primary outcome was a composite of death from CVD, non-fatal myocardial infarction or non-fatal stroke. Secondary outcomes were myocardial infarction, stroke, cardiovascular death and death from any cause. Cox models were used, with bootstrapping to compare associations between anthropometric measures for the primary outcome. RESULTS: Median follow-up time was 9.0 years. There was a positive association between WHtR and adverse outcomes. The hazard ratio (HR) (confidence interval), per SD higher WHtR, was 1.16 (1.11-1.22) for the primary endpoint, with no heterogeneity by sex or region, but a stronger effect in individuals aged 66 years or older. The other 3 anthropometric measurements showed similar associations, although there was evidence that WHtR marginally outperformed BMI and WHR. Based on commonly used BMI cut-points, the equivalent WHtR cut-points were estimated to be 0.55 and 0.6, with no evidence of a difference across subgroups. CONCLUSIONS: In patients with diabetes, WHtR is a useful indicator of future adverse risk, with similar effects in different population subgroups.

AIMS/HYPOTHESIS: Serum adiponectin has been reported to impact upon fracture risk in the general population. Although type 2 diabetes is associated with increased fracture risk, it is unclear whether serum adiponectin predicts fractures in individuals with type 2 diabetes. The aim of the study was to prospectively investigate the relationship between serum adiponectin and fracture risk in individuals with type 2 diabetes. METHODS: In this study, data was obtained from The Fukuoka Diabetes Registry, a multicentre prospective study designed to investigate the influence of modern treatments on the prognoses of patients with diabetes mellitus. We followed 4869 participants with type 2 diabetes (mean age, 65 years), including 1951 postmenopausal women (defined as self-reported amenorrhea for >1 year) and 2754 men, for a median of 5.3 years. The primary outcomes were fractures at any site and major osteoporotic fractures (MOFs). RESULTS: During the follow-up period, fractures at any site occurred in 682 participants, while MOFs occurred in 277 participants. Age-adjusted HRs (95% CIs) of any fracture and MOFs for 1 SD increment in log e -transformed serum adiponectin were 1.27 (1.15, 1.40) and 1.35 (1.17, 1.55) in postmenopausal women and 1.22 (1.08, 1.38) and 1.40 (1.15, 1.71) in men, respectively. HRs (95% CIs) of MOFs for hyperadiponectinaemia (≥ 20 µg/ml) were 1.72 (1.19, 2.50) in postmenopausal women and 2.19 (1.23, 3.90) in men. The per cent attributable risk of hyperadiponectinaemia for MOFs was as high as being age ≥70 years or female sex. CONCLUSIONS/INTERPRETATION: Higher serum adiponectin levels were significantly associated with an increased risk of fractures at any site and with an increased risk of MOFs in individuals with type 2 diabetes, including postmenopausal women.

BACKGROUND: Although statins deteriorate glucose metabolism, their glucose-lowering effects have emerged in some situations. Here, we assessed whether these effects are a consequence of statins' interaction with paraoxonase (PON)1 enzyme polymorphism. METHODS: Adult Japanese type 2 diabetes patients (n = 3798) were enrolled in a cross-sectional study. We used Q192R polymorphism of the PON1 gene as a representative single-nucleotide polymorphism and focused on the effects of the wild-type Q allele, in an additive manner. For patients with and without statin therapy, the associations of this allele with fasting plasma glucose (FPG), HbA1c, C-peptide, HOMA2-%ß, and HOMA2-IR were investigated separately using a linear regression model, and were compared between groups by testing interactions. Sensitivity analyses were performed using propensity score to further control the imbalance of characteristics between groups. RESULTS: Among patients with statin therapy, there were linear associations of the number of Q alleles with decreased FPG and HbA1c, and with increased serum C peptide and HOMA2-%ß (all P < 0.01 for trends), while such associations were not observed among those without statin therapy. These differences were statistically significant only for serum C peptide and HOMA2-%ß (P < 0.01 for interactions). These associations remained significant after multiple explanatory variable adjustment. Sensitivity analyses using propensity score showed broad consistency of these associations. CONCLUSIONS: Patients with the Q allele of the PON1 Q192R polymorphism who were treated with statins exhibited improvement in glucose metabolism, especially in insulin secretion, suggesting the importance of genotyping PON1 Q192R to identify those who could benefit from statin therapy.

BACKGROUND: The optimal cutoff values of the brachial-ankle pulse wave velocity (baPWV) for predicting cardiovascular disease (CVD) were examined in patients with hypertension.MethodsâandâResults:A total of 7,656 participants were followed prospectively. The hazard ratio for the development of CVD increased significantly as the baPWV increased, independent of conventional risk factors. The receiver-operating characteristic curve analysis showed that the optimal cutoff values for predicting CVD was 18.3 m/s. This cutoff value significantly predicted THE incidence of CVD. CONCLUSIONS: The present analysis suggests that the optimal cutoff value for CVD in patients with hypertension is 18.3 m/s.
