Background: The impact of targeting intensive glycemic control on the risk of developing renal complications in type 2 diabetes (T2DM) is controversial and an updated evidence is required from randomized clinical trials (RCTs).

Objectives: To conduct a meta-analysis of the effects of intensive versus standard glycemic control interventions on the risk of developing renal complications and death in T2DM.

Methods: Three scientific databases were searched for eligible RCTs and their updated post-hoc analyses to identify the impact of intensive glycemic control on the risk of incident microalbuminuria (MA) and doubling of serum creatinine (primary outcomes) as well as macroalbuminuria, ESRD, renal death and all-cause mortality (secondary outcomes). Pooled effect estimates and 95% confidence intervals (95% CIs) were computed based on risk ratios (RRs) and time-to-event data (hazard ratios [HRs]).

Results: A total of 13 articles (corresponding to eight RCTs) were included (31,111 patients, 61.23% males). The risks of MA, doubling of serum creatinine, ESRD, death from kidney disease, and all-cause mortality were not changed by intensive glucose control. However, the risk of macroalbuminuria decreased with the tight control compared to standard interventions (RR = 0.73, 95%CI, 0.66 to 0.80, p < 0.001 and HR = 0.71, 95%CI, 0.61 to 0.81, p < 0.001). Performance bias was evident in six trials (75%).

Conclusion: There was a 27% reduced risk of macroalbuminuria with intensive glucose control despite the lack of effects on other clinically meaningful outcomes of overt nephropathy. Future randomized studies should report renal outcomes based on large sample sizes, long-term follow-up periods, and using novel and reliable biomarkers of nephropathy.
