High levels of oxidized LDL in circulating immune complexes are associated with increased odds of developing abnormal albuminuria in Type 1 diabetes
Modified low-density lipoprotein (LDL) immune complexes (IC) have proinflammatory properties and play a role in albuminuria development.

Zusammenfassung: | Modified low-density lipoprotein (LDL) immune complexes (IC) have proinflammatory properties and play a role in albuminuria development.
We measured oxidized LDL (oxLDL) and advanced glycation end-product (AGE)-LDL in IC isolated from sera of Type 1 diabetic subjects followed for 14-20 years and studied their association with abnormal albuminuria. Patients with albumin excretion rates (AER)299 mg/24 h were considered as having macroalbuminuria (n=57). The odds of developing abnormal albuminuria were estimated by logistic regression based on natural log-transformed levels of oxLDL and AGE-LDL in IC and stratified by baseline AER decile.
OxLDL and AGE-LDL were significantly higher in IC isolated from patients progressing to abnormal albuminuria. In unadjusted conditional logistic analysis, an increase of 1 SD in oxLDL and AGE-LDL levels in IC significantly increased the odds ratio (OR) for development of macroalbuminuria, respectively, by a factor of 2.5 and 1.8 (P |
