Abstract

Objective: Antiphospholipid antibodies (aPL Abs) represented an independent factor that was associated with the occurrence and/or progression of nephropathy in patients with antiphospholipid syndrome, but their role in diabetic nephropathy is not elucidated. Therefore, we evaluated the association of aPL Abs with the renal impairment parameters in patients with diabetic nephropathy. Methods: Concentrations of analyzed antibodies were measured by enzyme-linked immunosorbent assay. Results: Cystatin C and anticardiolipin (aCL) antibodies of the immunoglobulin (Ig) G ( r = .349, P = .004) and the IgM isotype ( r = .316, P = .009) were in positive correlation. The IgG isotype of the aCL Abs was in positive correlation with creatinine ( r = .252, P = .038), urea ( r = .241, P = .048), and uric acid ( r = .271, P = .025). The concentrations of the IgG isotype of the aCL Abs were significantly different between subgroups of patients with diabetic polyneuropathy and patients without this clinical finding (Mann-Whitney, P = .033). Conclusion: This is the first report on positive correlation between aCL Abs and renal impairment parameters. Larger studies are necessary for elucidation whether this association is involved in further progression of the disease.
