| Sumario: | Aim of the work: To assess serum level of interleukin 23 (IL-23) in systemic lupus erythematosus (SLE) patients and to evaluate its association with disease parameters and activity. Patients and methods: The study involved 40 SLE patients and 40 controls. The SLE disease activity index (SLEDAI) and damage index (SDI) were assessed. Serum level of IL-23 was measured by enzyme linked immunosorbant assay (ELISA). Results: Patients were 38 females and 2 males (F:M 19:1),with a mean age of 31.3 ± 7.5 years (17–50 years) and disease duration 4.8 ± 2.9 years (1–13 years). Their mean SLEDAI was 14.3 ± 6.8 (3–32) and SDI 0.4 ± 0.5 (0–2). 85% of patients had photosensitivity, alopecia in 60%, malar rash in 57.5%, oral ulcers 52.5%, arthralgia/arthritis 47.5%, serositis and lupus nephritis in 27.5%, discoid rash in 22.5% and neuropsychiatric in 2.5%. Mean serum level of IL-23 was significantly elevated in patients (107.9 ± 17.3 ng/L; 72.7–165.5 ng/mL) compared to controls (91.6 ± 19.1 ng/L; 57.6–140.3 ng/mL; p < 0.001). IL-23 was significantly elevated in patients with oral ulcers (p = 0.03), arthritis (p < 0.001), lupus nephritis (p = 0.01), alopecia (p = 0.02) and positive anti-dsDNA (p < 0.001). IL-23 significantly correlated with SLEDAI (r = 0.89, p < 0.001), complement C3 (r = -0.55, p < 0.001) and C4 (r = -0.5, p = 0.001). IL-23 could significantly predict SLE at a cut-off 93.1 ng/L (sensitivity 80% and specificity 55%). Conclusion: IL-23 may be involved in the pathogenesis of SLE; especially in renal, mucocutaneous and musculoskeletal manifestations and it can be used as a disease activity biomarker. These findings support the possibility of its use as a therapeutic target in SLE. |
