Context

Diabetic kidney disease (DKD) is the leading cause of end-stage kidney disease (ESKD). Randomised controlled trials (RCTs) suggest that intensive glycaemic control reduces progression of albuminuria, but effects on later DKD stages and cardiovascular outcomes are less clear. This systematic review evaluated the benefits and harms of intensive versus standard glycaemic control on the onset and progression of DKD and mortality.

Methods

This meta-analysis of published tabular data included RCTs assigning patients with diabetes (type 1 or 2) with and without kidney disease to intensive (glycated haemoglobin (HbA1c) <7% or fasting blood glucose (FBG) <6.6 mmol/L) or standard glycaemic control (HbA1c ≥7% or FBG ≥6.6 mmol/L). Primary outcomes were doubling of serum creatinine, ESKD, and death or non-fatal myocardial infarction or stroke. Secondary outcomes included measures of albuminuria, serum creatinine, measures of glomerular …
