Accumulating evidence has demonstrated that both SGLT2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP1Ra) have protective effects in patients with diabetic kidney disease. Combination therapy with SGLT2i and GLP1Ra is commonly used in patients with type 2 diabetes (T2D). We previously reported that in combination therapy of SGLT2i and GLP1Ra, the effect on the renal composite outcome did not differ according to the preceding drug. However, it remains unclear how the initiation of combination therapy is associated with the renal function depending on the preceding drug. In this post hoc analysis, we analyzed a total of 643 T2D patients (GLP1Ra-preceding group, n = 331; SGLT2i-preceding group, n = 312) and investigated the differences in annual eGFR decline. Multiple imputation and propensity score matching were performed to compare the annual eGFR decline. The reduction in annual eGFR decline in the SGLT2i-preceding group (pre: −3.5 ± 9.4 mL/min/1.73 m2/year, post: −0.4 ± 6.3 mL/min/1.73 m2/year, p < 0.001), was significantly smaller after the initiation of GLP1Ra, whereas the GLP1Ra-preceding group tended to slow the eGFR decline but not to a statistically significant extent (pre: −2.0 ± 10.9 mL/min/1.73 m2/year, post: −1.8 ± 5.4 mL/min/1.73 m2/year, p = 0.83) after the initiation of SGLT2i. After the addition of GLP1Ra to SGLT2i-treated patients, slower annual eGFR decline was observed. Our data raise the possibility that the renal benefits—especially annual eGFR decline—of combination therapy with SGLT2i and GLP1Ra may be affected by the preceding drug.

ABSTRACT Aims/Introduction We previously reported that sodium–glucose cotransporter 2 inhibitor (SGLT2i) treatment was associated with an improvement of the albumin‐to‐creatinine ratio in Japanese patients with type 2 diabetes mellitus and chronic kidney disease. The present study clarified how concomitant insulin treatment (IT) with SGLT2i therapy influences the renal composite outcome (RCO). Materials and Methods We retrospectively evaluated 624 Japanese patients with type 2 diabetes mellitus and chronic kidney disease who underwent SGLT2i treatment. The renal composite outcome was set as progression of the stage of albuminuria or a ≥15% decrease in the estimated glomerular filtration rate per year. We developed a cohort model of patients managed with and without IT (Ins [+], Ins [−]) using propensity score matching methods. Furthermore, all patients in our study population were stratified into quintiles according to their propensity score. Results The incidence of the RCO was in Ins (+) patients significantly higher than that in Ins (−) (P = 0.033). The estimated hazard ratio for the RCO was 1.55 (P = 0.035) in Ins (+) patients. The change in the estimated glomerular filtration rate and albumin‐to‐creatinine ratio in the groups was not statistically significant. The analysis, which was based on the quintiles, showed a statistically significant difference between the Ins (+) and Ins (−) groups (P = 0.01); the odds ratio for the RCO in patients managed with IT was 2.20 (P = 0.01). Conclusions Concomitant administration of IT with SGLT2is influenced the RCO in Japanese patients with type 2 diabetes mellitus and chronic kidney disease. We might need to consider the influence of concomitant agents on the renoprotective effects of SGLT2i therapy.

Abstract Aims/Introduction After the first coronavirus disease 2019 state of emergency announcement, there was an increase in stress that might have affected the self‐management of patients with type 2 diabetes mellitus. This study identified the changes in clinical findings and stress among patients with type 2 diabetes mellitus, and investigated the characteristics of patients who experienced an increase in blood pressure (BP) after the announcement. Materials and Methods Retrospectively, we scrutinized 310 patients with type 2 diabetes mellitus who were treated by the Sagamihara Physicians Association. After the announcement, 164 and 146 patients showed an increase (ΔBP >0 group) and decrease in BP (ΔBP ≤0 group), respectively. The propensity score matching method was used to compare the differences in clinical findings and stress‐related questionnaire responses between the two groups. Results After the announcement, 47% of patients experienced an increase in daily stress. Furthermore, 17% and 36% reported worsening dietary intake and a decrease in exercise, respectively. More patients reported that their dietary and salt intake had worsened in the ΔBP >0 group than in the ΔBP ≤0 group (9% vs 20%, P = 0.02, and 3% vs 10%, P = 0.04, respectively). Additionally, both systolic and diastolic BP measured in the office were significantly increased (P = 0.02 and P = 0.03, respectively); however, systolic BP measured at home significantly decreased (P = 0.01). The total stress scores were higher in the ΔBP >0 group than in the ΔBP ≤0 group (0.05 ± 2.61 and 0.93 ± 2.70, respectively, P = 0.03). Conclusions An increase in stress and, particularly, worsening dietary and salt intake were noted among patients with type 2 diabetes mellitus who experienced an increase in BP after the state of emergency announcement.

Abstract The cardiovascular and renal protective effects of sodium-glucose cotransporter 2 inhibitors (SGLT-2is) and glucagon-like peptide 1 receptor agonists (GLP-1Ras) are enhanced by low/controlled blood pressure (BP). However, the BP-lowering efficacy of SGLT-2is and GLP-1Ras have not been compared directly. We compared the rates of achieving target BP with SGLT-2i and GLP-1Ra treatments in Japanese patients with type 2 diabetes mellitus (T2DM). This retrospective study included 384 SGLT-2i- and 160 GLP-1Ra-treated patients with BP > 130/80 mmHg before treatment. Inverse probability weighting methods using propensity scores were used in this study. The integrated odds ratios (OR) for BP control rates were calculated and clinical changes were analyzed using a generalized linear model. SGLT-2i treatment resulted in significantly higher BP control rates than that in the GLP-1Ra treatment (integrated OR = 2.09 [1.80, 2.43]). Compared with GLP-1Ra, SGLT-2i treatment demonstrated significantly larger decreases in diastolic BP, mean arterial pressure, and body weight (− 3.8 mmHg, P = 0.006; − 4.1 mmHg, P = 0.01; and − 1.5 kg, P = 0.008, respectively) and increased annual estimated glomerular filtration rate (eGFR; 1.5 mL/min/1.73 m2/year, P = 0.04). In T2DM patients with poorly controlled BP, compared with GLP-1Ra, SGLT-2i treatment significantly improved BP management and increased eGFR.

Abstract Polypharmacy is a serious concern in general practice, especially among elder patients; however, the evidence showing significantly poor renal outcomes is not sufficient. This survey was performed to evaluate the effect of polypharmacy on the incidence of the renal composite outcome among a sample of patients with sodium‐glucose cotransporter 2 inhibitor (SGLT2i) treatment. We assessed 624 Japanese patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease who received SGLT2i treatment for greater than 1 year. The patients were classified as those with concomitant treatment, that was limited to the medications for hypertension, T2DM, and dyslipidemia, with greater than or equal to seven medications (n = 110) and those with less than seven medications (n = 514). Evaluation of the renal composite outcome was performed by propensity score matching and stratification into quintiles. A subgroup analysis of patients of greater than or equal to 62 years of age and less than 62 years of age was also performed. The incidence of the renal composite outcome was larger in patients with greater than or equal to seven medications than in those with less than seven medications in the propensity score‐matched cohort model (6% vs. 17%, respectively, p = 0.007) and also in the quintile‐stratified analysis (odds ratio [OR], 2.23, 95% confidence interval [CI, 1.21–4.12, p = 0.01). The quintile‐stratified analysis of patients of less than 62 years of age—but not those of greater than or equal to 62 years of age—also showed a significant difference (OR, 3.29, 95% CI, 1.41–7.69, p = 0.006). Polypharmacy appears to be associated to the incidence of the renal composite outcome, especially in young patients.

Abstract Aims/Introduction Large‐scale clinical trials have reported that, in patients with type 2 diabetes mellitus, sodium–glucose cotransporter 2 (SGLT2) inhibitor treatment affords favorable renal outcomes; the underlying mechanisms, however, remain unclear. Thus, this study investigated how SGLT2 inhibitor‐induced changes in the mean arterial pressure (MAP; denoted as ΔMAP) are associated with renal outcomes in type 2 diabetes mellitus patients with chronic kidney disease (CKD). Materials and Methods We retrospectively assessed the data of 624 Japanese type 2 diabetes mellitus patients with CKD who had been using SGLT2 inhibitors for >1 year. For propensity score matching (1:1 nearest neighbor match, with caliper value = 0.053, no replacement), patients were categorized into two groups based on the ΔMAP (>−4 mmHg [n = 329] and ≤−4.0 mmHg [n = 295]). Composite albuminuria progression or a ≥15% annual reduction in the estimated glomerular filtration rate was regarded as the end‐point. Results Per group, 173 propensity‐matched patients were compared. Patients with ΔMAP ≤−4 mmHg had a significantly lower incidence of composite renal outcomes than those with ΔMAP ≥−4 mmHg (5.8% [n = 10] vs 15.6% [n = 27], P = 0.003). Although the between‐group differences in the estimated glomerular filtration rates were non‐significant, patients with a ΔMAP ≤−4 mmHg had significantly larger reductions in the logarithmic urine albumin‐to‐creatinine ratio (P = 0.005). Conclusions The degree of blood pressure reduction after SGLT2 inhibitor treatment influenced renal composite outcomes in Japanese type 2 diabetes mellitus patients with CKD, confirming the importance of blood pressure management in type 2 diabetes mellitus patients with CKD, even when they are under SGLT2 inhibitor treatment.

Decrease in blood pressure contributes to the reno-protective effects of sodium-glucose cotransporter 2 inhibitors; however, its relationship with home monitoring of blood pressure is unclear. We retrospectively analyzed 101 visiting members of the Kanagawa Physicians Association with type 2 diabetes mellitus and chronic kidney disease who were taking sodium-glucose cotransporter 2 inhibitors and who monitored blood pressure at home for a median treatment period of 14 months. At baseline, the mean value of HbA1c was 59.3 mmol/mol (7.6%) and the median value of albumin-creatinine ratio was 30.9 mg/gCr that was evaluated in 88 patients. The mean blood pressure both at office and home significantly decreased, and there was a significant positive correlation between the change in albumin–creatinine ratio and both blood pressures. Controlled hypertension, masked hypertension, white coat hypertension, and sustained hypertension were observed in 10.9%, 13.9%, 12.9%, and 62.4% of patients at the initiation of therapy, which changed to 10.9%, 16.8%, 17.8%, and 54.5% at the time of the survey, respectively. In conclusion, management of blood pressure both at office and home was found to be important for the reno-protective effects of sodium-glucose cotransporter 2 inhibitors along with strict blood pressure management.

Background and Aim. Strong evidence exists supporting the utility of sodium glucose cotransporter inhibitors (SGLT2is) for treating not only cardiovascular events but also renal events. We previously reported that SGLT2is improved the urine albumin-to-creatine ratio (ACR) in Japanese patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). Only 8% of patients were treated with SGLT2is alone, and more than 70% of them additionally received incretin-related agents, such as dipeptidyl peptidase 4 inhibitor (DPP4i) and glucagon-like peptide 1 agonist (GLP1Ra). Both agents reduce the plasma glucose level with an incretin effect, but the differences in the renoprotective effects between these agents are poorly understood. Methods. We retrospectively constructed database of 763 Japanese patients with T2DM and CKD who received sSGLT2is for more than 1 year. Among these SGLT2i-treated patients, 338 were receiving concomitant DPP4i (DPP4i group), and 99 were receiving concomitant GLP1Ra (GLP1Ra group). The two groups were compared using the propensity score matching method. Results. In the matched model including 86 cases per group, the decrease in the logarithmic value of the ACR and rate of reduction in the estimated glomerular filtration rate (eGFR; mL/min/1.73 m2) of the GLP1Ra group showed no significant difference from those in the DPP4i group (−0.12±0.48 vs. −0.13±0.45 and −2.3±18.5 vs. −6.2±13.8, respectively, P=0.10). However, the incidence of a >6.4% decrease in the eGFR was significantly lower in the GLP1Ra group than in the DPP4i group (35% vs. 52%, respectively, P=0.03). The level of hemoglobin A1c (mmol/mol) after SGLT2i treatment was significantly lower in the DPP4i group than in the GLP1Ra group in the matched model (58.3±11.8 and 62.7±14.8, respectively, P=0.02). Conclusion. Among the SGLT2i-treated patients with T2DM and CKD, concomitant treatment with GLP1Ra has a marked improving effect on the change in the eGFR.

To evaluate the Japanese Society of Hypertension Guidelines for the Management of Hypertension 2014 (JSH2014) among Japanese general practitioners (GPs), we used a questionnaire survey with 209 GPs from the Kanagawa Physicians Society. Overall, 93.6% of GPs felt that the contents of the JSH2014 were useful. Based on the results showing that 81.8% of GPs instructed the measurement of blood pressure (BP) in the early morning at home to most patients, GP’s acceptance of home BP methods and their penetration among patients with hypertension were considerably high. Regarding the number of home BP measurements, percentages for “one time,” “two times,” “three times,” and “as many times as the patient decides,” were 20.2%, 44.9%, 12.2%, and 22.9%, respectively; as such, no consensus was reached. Overall, 80.6% of GPs instructed most patients on sodium restriction; however, the content and method of restriction varied. Furthermore, 14.7% collected spot urine to assess salt intake. Many GPs respected the JSH2014 and faithfully adopted the guidelines during medical care. However, GPs did not necessarily agree with all guidelines. GPs sometimes selected the appropriate method for the individual patients and careful observations of how the guidelines affect actual clinical practice may lead to better medical care.

Background: Atrial fibrillation (AF) is one of the most prevalent cardiac arrhythmias associated with substantially increased risks of ischemic stroke and thromboembolism. Oral anticoagulants (OACs) are the cornerstone of AF management and effectively prevent AF-related stroke. As new non-vitamin K antagonist OACs (NOACs) have become available, the landscape of stroke prevention in AF has changed. However, there are considerable gaps between daily clinical practice and current guideline-based recommendations for anticoagulant therapy in Japan. Consequently, little is known about the real-world setting and the current use of NOACs, especially by practitioners in Japan. Methods: We conducted a prospective, observational study in 3847 patients with AF who were enrolled in clinics and hospitals located in Kanagawa Prefecture from September 2013 through March 2015. The participating centers included practitioners (small clinics), medium-sized hospitals, and university hospitals. The primary endpoints were epidemiologic characteristics, status of treatment with anticoagulants and antiplatelet agents, outcomes, and adverse events, including cerebrovascular disease, bleeding, and death. Results: The mean CHADS2 score was 1.81±1.27, the mean CHADS2-Vasc score was 3.02±1.58, and the mean HAS-BLED score was 2.23±1.06, respectively. The usage rate of warfarin was 44.2% overall, and the usage rate of NOACs was 33.5%. Conclusions: The results of the study are expected to serve as the basis for providing clinical practice guidance to healthcare institutions in Japan, with the ultimate goals of better characterizing the appropriate use of OACs and providing clinical decision support to physicians to facilitate the design of appropriate therapeutic strategies and the selection of anticoagulants for the management of AF.

Aim. The renoprotective effect of sodium-glucose cotransporter 2 inhibitors is thought to be due, at least in part, to a decrease in blood pressure. The aim of this study was to determine the renal effects of these inhibitors in low blood pressure patients and the dependence of such effect on blood pressure management status. Methods. The subjects of this retrospective study were 740 patients with type 2 diabetes mellitus and chronic kidney disease who had been managed at the clinical facilities of the Kanagawa Physicians Association. Data on blood pressure management status and urinary albumin-creatinine ratio were analyzed before and after treatment. Results. Changes in the logarithmic value of urinary albumin-creatinine ratio in 327 patients with blood pressure

We performed a cross-sectional survey to investigate actual clinical practice concerning blood-pressure control among patients with hypertension in Kanagawa. The guidelines of the Japanese Society of Hypertension (JSH) for the management of patients with hypertension were revised in 2014. From October 1 to November 30, 2014, questionnaires on the care of patients with hypertension were sent via post to members of the Kanagawa Physicians Association in Kanagawa Prefecture, Japan. -Data on 1,105 patients (mean age: 68.4±12.3 years, 537 men and 568 women) were obtained. The overall mean systolic blood pressure (BP) of these patients was 128.7±12.1 mmHg for home monitoring and 132.9±12.6 mmHg for office monitoring; diastolic BP was 75.7±9.7 for home monitoring and 77.0±9.7 mmHg for office monitoring. According to the JSH 2014 guidelines, the target BP was achieved by 68.1% of all subjects; 89.2% of late-phase elderly patients (75 years or older); 69.1% of young, middle-aged, and earlyphase elderly patients (younger than 75 years except in patients with diabetes mellitus [DM] or chronic kidney disease [CKD] with proteinuria); 9.3% of patients with DM except late-phase elderly patients; and 11.9% of CKD patients with proteinuria except DM. Cross-sectional analysis showed that the factors significantly associated with an increased likelihood of achieving the target BP were as follows: 1) good medication compliance even for a small number of antihypertensive agents at small amount of doses in patients 75 years and older; 2) good medication compliance in patients in younger than 75 years; 3) an older age, a larger proportion in the female-to-male ratio and a lower body mass index in patients with DM except late-phase elderly patients; and 4) usage of a large number of antihypertensive agents in CKD patients with proteinuria. Further follow-up surveys are necessary to investigate changes in clinical practice following the introduction of the revised guidelines. [ABSTRACT FROM AUTHOR]

We performed cross-sectional surveys to investigate changes in clinical practices regarding blood-pressure control in patients with hypertension from 2008 through 2011. Questionnaires regarding the care of patients with hypertension were mailed to members of the Kanagawa Physicians Association in Kanagawa Prefecture, Japan. Data were obtained on 675 patients in 2008, 332 in 2009, and 1,076 in 2011. The mean systolic blood pressure (BP) was significantly lower in 2011 than in 2008 (132.2±11.9 mm Hg versus 134.6±10.6mm Hg). The office-measured target BP, according to the 2009 guidelines of the Japanese Society of Hypertension for the management of patients with hypertension, was achieved in 53.9% of patients in 2008, 55.1% in 2009, and 57.1% in 2011. In nonelderly patients (younger than 65 years), the achievement rate was significantly greater in 2011 (41.2%) than in 2008 (23.6%). This analysis showed that the factor most significantly associated with a decrease in officemeasured BP was treatment with a larger number and higher doses of antihypertensive agents. To investigate changes in clinical practices according to the guidelines, further followup surveys are necessary. [ABSTRACT FROM AUTHOR]
