Metabolic syndrome and concomitant diabetes mellitus are associated with higher risk of cardiovascular comorbidity in patients with primary glomerular diseases: A retrospective observational study

Abstract

Background: Metabolic syndrome (MS) and diabetes mellitus (DM) are risk factors for cardiovascular diseases in general population. However, there was a paucity of studies investigating their impact in primary glomerular diseases (PGD). Hypothesis: MS and concomitant DM are associated with higher risk of cardiovascular comorbidity in PGD. Methods: In a retrospective observational design, we analyzed 3622 hospitalized adult PGD patients and compared the prevalence of cardiovascular comorbidity in non-MS, MS with and without DM. Risk factors for cardiovascular comorbidity were identified using univariate and multivariate logistic regression. Results: Among 3622 PGD patients, 308 (8.5%) cases accompanied with MS, including 180 (5.0%) patients with DM and 128 (3.5%) without DM. One hundred and sixty four (4.5%) cases coexisted with cardiovascular comorbidity. Patients with MS and concomitant DM exhibited a higher prevalence of cardiovascular comorbidity than those without MS stratified by estimated glomerular filtration rate and pathological types. Logistic regression showed that MS and concomitant DM (OR: 2.496, 95% CI: 1.600-3.894, P
