Risk of cardiovascular disease, death, and renal progression in diabetes according to albuminuria and estimated glomerular filtration rate - 10/03/23
for the China Cardiometabolic Disease and Cancer Cohort (4C) Study Group#
Highlights |
• | More than half of DM patients with reduced eGFR had normal ACR levels in China. |
• | Non-albuminuria DKD patients showed increased risks of mortality and MACEs. |
• | Risks of MACEs and mortality were more evident in non-albuminuria DKD aged <65 years. |
• | Non-albuminuria DKD did not significantly increase the risk of CKD progression. |
• | DM patients with albuminuria are at higher risks than those with non-albuminuria DKD. |
Abstract |
Aim |
We aimed to examine risks of major cardiovascular events (MACEs), renal outcomes, and all-cause mortality in type 2 diabetes mellitus (T2DM) patients with different diabetic kidney disease (DKD) subtypes.
Methods |
A total of 36,509 participants with T2DM recruited from 20 community sites across mainland China were followed up during 2011-2016. DKD subtypes were categorized based on albuminuria (urinary albumin-to-creatinine ratio, UACR ≥ 30 mg/g) and reduced estimated glomerular filtration rate (eGFR < 60 ml/min/1.73 m2) as Alb−/eGFR−, Alb+/eGFR−, Alb−/eGFR+, and Alb+/eGFR+. Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs) of developing clinical outcomes in DKD subtypes.
Results |
More than half (53.5%) of participants with diabetes and reduced eGFR had normal UACR levels (Alb−/eGFR+), termed as non-albuminuria DKD. These patients had a modest increase in the risks of MACEs (hazard ratio, HR 1.42 [95% CI 1.08;1.88]) and mortality (HR 1.42 [1.04;1.92]) compared with patients without DKD, whereas CKD progression was not significantly increased (HR 0.97 [0.60;1.57]). Participants with albuminuria (Alb+/eGFR− or Alb+/eGFR+) had higher risks of clinical outcomes. Subgroup analysis revealed that the associations between non-albuminuria DKD and risks of MACEs and mortality were more evident in those aged <65 years.
Conclusion |
Non-albuminuria DKD accounts for more than half of DKD cases with low eGFR in Chinese diabetes patients. Diabetes patients with albuminuria are at higher risks of developing clinical outcomes and warrant early intervention, as well as patients with non-albuminuria DKD with age < 65 years.
