Cerebral microvascular disease predicts renal failure in type 2 diabetes.

ABSTRACT: Abnormalities in small renal vessels may increase the risk of developing impaired renal function, but methods to assess these vessels are extremely limited. We hypothesized that the presence of small vessel disease in the brain, which manifests as silent cerebral infarction (SCI), may predict the progression of kidney disease in patients with type 2 diabetes. We recruited 608 patients with type 2 diabetes without apparent cerebrovascular or cardiovascular disease or overt nephropathy and followed them for a mean of 7.5 years. At baseline, 177 of 608 patients had SCI, diagnosed by cerebral magnetic resonance imaging. The risk for the primary outcome of ESRD or death was significantly higher for patients with SCI than for patients without SCI [hazard ratio, 2.44; 95% confidence interval (CI) 1.36 to 4.38]. The risk for the secondary renal end point of any dialysis or doubling of the serum creatinine concentration was also significantly higher for patients with SCI (hazard ratio, 4.79; 95% CI 2.72 to 8.46). The estimated GFR declined more in patients with SCI than in those without SCI; however, the presence of SCI did not increase the risk for progression of albuminuria. In conclusion, independent of microalbuminuria, cerebral microvascular disease predicted renal morbidity among patients with type 2 diabetes.

Project description:AimsThe relationship between diabetic microvascular complications and the incidence of two types of heart failure-heart failure with reduced ejection fraction (HFrEF) (left ventricular ejection fraction [LVEF] < 40%) and non-HFrEF (LVEF ≥ 40%)-in patients without prior heart failure has not been clarified. We herein examined the association between diabetic microvascular complications and HFrEF or non-HFrEF in patients with type 2 diabetes mellitus (T2DM) without prior heart failure.Methods and resultsIn this retrospective cohort study, we assessed the relationship between the presence of diabetic microvascular complications or severity of diabetic retinopathy (no apparent, non-proliferative and proliferative retinopathy) and nephropathy (normoalbuminuria, microalbuminuria, and macroalbuminuria) at baseline, with the primary outcome of first heart failure hospitalization classified as HFrEF or non-HFrEF in patients with type 2 diabetes mellitus without prior heart failure. Among 568 patients (69.2% males, mean age 66.2 ± 9.6 years), 70 experienced heart failure hospitalization (HFrEF: 24 and non-HFrEF: 46). Non-HFrEF hospitalization but not HFrEF hospitalization was significantly associated with the presence of diabetic microvascular complications. The incidence of non-HFrEF hospitalization was significantly higher in the proliferative retinopathy group than that in the no apparent retinopathy group (adjusted hazard ratio [HR] 2.96, 95% confidence interval [CI]: 1.09-6.83, P = 0.035) and in those with macroalbuminuria than in those with normoalbuminuria (adjusted HR 4.23, 95% CI: 2.24-7.85, P < 0.001) even after adjustment for age and sex. When non-HFrEF was classified into heart failure with mildly reduced ejection fraction (HFmrEF) (40% ≤ LVEF < 50%) and heart failure with preserved ejection fraction (HFpEF) (50% ≤ LVEF), HFmrEF and HFpEF hospitalizations were also found to be associated with the progression of retinopathy and nephropathy.ConclusionsIn patients with T2DM without prior heart failure, non-HFrEF hospitalization was more closely associated with the progression of diabetic microangiopathy than HFrEF. The development of non-HFrEF may be mediated through a mechanism similar to that of microvascular complications in these patients.
