Effect of preceding drug therapy on the renal and cardiovascular outcomes of combined sodium-glucose cotransporter-2 inhibitor and glucagon-like peptide-1 receptor agonist treatment in patients with type 2 diabetes and chronic kidney disease.

Aim: To conduct a post hoc subgroup analysis of patients with type 2 diabetes (T2D) from the RECAP study, who were treated with sodium-glucose cotransporter-2 (SGLT2) inhibitor and glucagon-like peptide 1 receptor agonist (GLP-1RA) combination therapy, focusing only on those patients who had chronic kidney disease (CKD), to examine whether the composite renal outcome differed between those who received SGLT2 inhibitor treatment first and those who received a GLP-1RA first.

Methods: We included 438 patients with CKD (GLP-1RA-first group, n = 223; SGLT2 inhibitor-first group, n = 215) from the 643 T2D patients in the RECAP study. The incidence of the composite renal outcome, defined as progression to macroalbuminuria and/or a ≥50% decrease in estimated glomerular filtration rate (eGFR), was analysed using a propensity score (PS)-matched model.

Pretreatment body mass index affects achievement of target blood pressure with sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes mellitus and chronic kidney disease.

Sodium-glucose cotransporter 2 inhibitor (SGLT2-I) shows excellent antihypertensive effects in addition to its hypoglycemic effects. However, whether body mass index (BMI) affects the antihypertensive effect of SGLT2-I remains unknown. We investigated the impact of baseline BMI on the achievement of target blood pressure (BP) with SGLT2-I treatment in Japanese patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD).

The concomitant use of sodium-glucose co-transporter 2 inhibitors improved the renal outcome of Japanese patients with type 2 diabetes treated with glucagon-like peptide 1 receptor agonists.

Aims: This study aimed to clarify the renal influence of glucagon-like peptide 1 receptor agonists (GLP1Ras) with or without sodium-glucose co-transporter 2 inhibitors (SGLT2is) on Japanese patients with type 2 diabetes mellitus (T2DM).

Methods: We retrospectively extracted 547 patients with T2DM who visited the clinics of members of Kanagawa Physicians Association. The progression of albuminuria status and/or a ≥ 15% decrease in the estimated glomerular filtration rate (eGFR) per year was set as the renal composite outcome.

Cross-sectional survey of hypertension management in clinical practice in Japan: the Kanagawa Hypertension Study 2021 conducted in collaboration with Japan Medical Association Database of Clinical Medicine.

We aim to assess the data of patients with hypertension in Kanagawa Prefecture, Japan, collected in 2021 that were provided by the Japan Medical Association Database of Clinical Medicine. Data collected in 2011 and 2014 by the Kanagawa Physicians Association were used for comparative analysis. The target blood pressure (BP) achievement rates for patients whose target office and home BP were <140/90 mmHg and <135/85 mmHg, respectively, were 72.

Comparison of the blood pressure management between sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists.

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).

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.

Comparison of renal outcomes between sodium glucose co-transporter 2 inhibitors and glucagon-like peptide 1 receptor agonists.

Aims: This study aimed to clarify the differences in how sodium glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP1Ra) influence kidney function in Japanese patients with type 2 diabetes mellitus (T2DM).

Methods: We retrospectively built two databases of patients with T2DM who visited the clinics of members of Kanagawa Physicians Association. We defined the renal composite outcome as either progression of albuminuria status and/or > 15% deterioration in estimated glomerular filtration rate (eGFR) per year.

The Comparison of the Kidney Effects of Dipeptidyl Peptidase 4 Inhibitors and Glucagon-Like Peptide 1 Agonist-Administered Concomitant with Sodium-Glucose Cotransporter 2 Inhibitors in Japanese Patients with Type 2 Diabetes Mellitus and Chronic Kidney Disease.

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.

Polypharmacy influences the renal composite outcome in patients treated with sodium-glucose cotransporter 2 inhibitors.

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.

Background: In 2019, a nationwide questionnaire survey on the management of chronic kidney disease (CKD) was circulated to general practitioners (GPs) throughout Japan by The Japan Physicians Association. The aim was to assess the current state of CKD medical care in the country and evaluate the utilization of CKD-specific guidelines in the treatment by GPs.

Methods: The voluntary survey targeted all members of Japan Physicians Association, a nationwide organization consisting primarily of 15,000 GPs in clinics throughout the country.

Development of an efficient one-step real-time reverse transcription polymerase chain reaction method for severe acute respiratory syndrome-coronavirus-2 detection.

The general methods to detect the RNA of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) in clinical diagnostic testing involve reverse transcriptases and thermostable DNA polymerases. In this study, we compared the detection of SARS-CoV-2 by a one-step real-time RT-PCR method using a heat-resistant reverse transcriptase variant MM4 from Moloney murine leukemia virus, two thermostable DNA polymerase variants with reverse transcriptase activity from Thermotoga petrophila K4 and Thermococcus kodakarensis KOD1, or a wild-type DNA polymerase from Thermus thermophilus M1. The highest performance was achieved by combining MM4 with the thermostable DNA polymerase from T.
