| Popis: | Objective The aim of the study was to study insulin resistance (IR) and pancreatic b-cell function in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and their relationship with disease activity. Background IR is an important contributor to the increased cardiovascular risk attributed to the metabolic syndrome, a constellation of cardiovascular risk factors that includes central obesity, dyslipidemia, hypertension, and disturbed glucose metabolism, in patients with RA or SLE. Patients and methods The study included 35 SLE and 35 RA patients and 20 controls. Disease activity was assessed by Systemic Lupus Activity Measure score and Disease Activity Score-28. BMI, C-reactive protein, erythrocyte sedimentation rate, lipid profile, fasting glucose and insulin, and c-peptide were determined. The homeostasis model of assessment (HOMA) was used to evaluate IR and secretion. Results SLE patients had high-grade systemic inflammation, IR, and secretion compared with controls ( P P Conclusion The present study demonstrated that both SLE and RA patients had a higher IR and abnormal insulin secretion than age-matched apparently healthy controls. This conclusion was based on the measurement of fasting insulin concentration, HOMA IR, and HOMA b-cells. IR and abnormal insulin secretion were associated with markers for inflammation (erythrocyte sedimentation rate and C-reactive protein) and disease activity indices (Systemic Lupus Activity Measure and Disease Activity Score-28). Higher IR and abnormal insulin secretion were found in RA patients in comparison with SLE patients. |
