Objectives To assess mortality and cardiovascular and renal outcomes among patients with chronic kidney disease (CKD) (primary objective), with a particular focus on heart failure (HF) risk following diagnosis of CKD (secondary objective) in Spain. Methods We conducted an observational study comprising cross-sectional and longitudinal retrospective analyses using secondary data from electronic health records. For the primary objective, adults with prevalent CKD [estimated glomerular filtration rate (eGFR) <60 or ≥60 mL/min/1.73 m2 with a urine albumin:creatinine ratio (UACR) ≥30 mg/g at the index date (1 January 2017)] were included. For the secondary objective, adults with incident CKD in 2017 were enrolled. Results In the prevalent population, 46 786 patients with CKD without HF [75.8 ± 14.4 years, eGFR 51.4 ± 10.1 mL/min/1.73 m2; 75.1% on renin–angiotensin system inhibitors (RASis)] and 8391 with CKD and HF (79.4 ± 10.9 years, eGFR 46.4 ± 9.8 mL/min/1.73 m2) were included. In the prevalent population, the risk of all-cause death {hazard ratio [HR] 1.107 [95% confidence interval (CI) 1.064–1.153]}, HF hospitalization [HR 1.439 (95% CI 1.387–1.493)] and UACR progression [HR 1.323 (95% CI 1.182–1.481)] was greater in those patients with CKD and HF versus CKD only. For the incident population, 1594 patients with CKD without HF and 727 with CKD and HF were included. Within 24 months from the CKD diagnosis (with/without HF at baseline), 6.5% of patients developed their first HF hospitalization. Although 60.7% were taking RASis, only 3.4% were at maximal doses and among diabetics, 1.3% were taking sodium-glucose cotransporter-2 inhibitors. Conclusions The presence of HF among CKD patients markedly increases the risk of outcomes. CKD patients have a high risk of HF, which could be partially related to insufficient treatment.

Background This study was designed to evaluate the efficiency and safety of combination therapy with sodium–glucose cotransporter 2 (SGLT2) inhibitors and renin–angiotensin system blockers such as angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) in patients with type 2 diabetes mellitus (T2DM). Methods We searched the PubMed, Embase, Web of Science and Cochrane Library databases from their inception to May 2020. Two authors independently performed study selection, risk-of-bias assessment and data extraction. The quality and risk of bias were assessed by the Cochrane Risk of Bias Tool. Statistical heterogeneity was determined by the I 2 statistics. Results Seven studies including 1757 patients were analysed. Compared with ACEI/ARB alone, combination therapy with SGLT2 inhibitors and ACEIs/ARBs produced a reduction in systolic blood pressure (SBP) [weighted mean difference (WMD) −3.84 mmHg], diastolic blood pressure (DBP; WMD −1.06 mmHg), 24 h ambulatory SBP (WMD −4.59 mmHg), 24-h ambulatory DBP (WMD −2.08 mmHg), urine albumin:creatinine ratio (WMD −29.70%), evaluated glomerular filtration rate (WMD −3.46 mL/min/1.73 m2), haemoglobin A1c [standardized mean difference (SMD) −0.48], fasting plasma glucose (SMD −0.28), uric acid (SMD −0.35) and body weight (SMD −0.29). The risk of hypoglycaemia with combination therapy was higher than in the control group (risk ratio 1.37). As for the risks of total adverse events, genital infection and urinary tract infection, no significant difference was revealed. Conclusion Compared with ACEI/ARB alone, the combination therapy with SGLT2 inhibitors and ACEIs/ARBs in T2DM was effective and well-tolerated and could achieve additional effects including better control of blood pressure, improvement of renal outcomes, alleviation of long-term renal function and a decrease in blood glucose and body weight. The combination therapy showed an increased risk of hypoglycaemia. [ABSTRACT FROM AUTHOR]

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have clearly demonstrated their beneficial effect in diabetic kidney disease (DKD) on top of the standard of care [blood glucose control, renin–angiotensin system blockade, smoking cessation and blood pressure (BP) control], even in patients with overt DKD. However, the indication of this drug class is still blood glucose lowering in type 2 diabetic patients with estimated glomerular filtration rate >45 mL/min/1.73 m2. Based on the new evidence, several scientific societies have emphasized the preferential prescription of SGLT2i for patients at risk of heart failure or kidney disease, but still within the limits set by health authorities. A rapid positioning of both the European Medicines Agency and the US Food and Drug Administration will allow patients with overt DKD to benefit from SGLT2i. Clinical experience suggests that SGLT2i safety management may in part mirror renin–angiotensin blockade safety management in patients with overt DKD. This review focuses on the rationale for an indication of SGTL2i in DKD. We further propose clinical steps for maximizing the safety of SGLT2i in DKD patients on other antidiabetic, BP or diuretic medication. [ABSTRACT FROM AUTHOR]
