Role of some Immunological and non-Immunological Parameters in Prognosis and diagnosis of Systemic lupus erythematosus in Iraqi women patients

Abstract

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by autoantibody's presence in the circulation and involvement of many systems. The current study aims to study the role of some immunological and non-immunological parameters in SLE development and to illustrate the correlations between these parameters. The current study included 50 blood samples collected from SLE patients and apparently healthy control. The methods of work included Complete Blood Count (CBC) analysis to assess blood components, you mean to analyse Hb, WBC, ESR, ELISA technique to measure serum levels of TLR-7, IL-17, and TNF-γ, antinuclear antibody test (ANA) and double-strand DNA antibody (anti ds DNA). The study results showed a significant increase in serum levels of each WBC (p< 0.005), ESR (p< 0.001), IL17(p< 0.004), TLR7(p< 0.005), IFN-γ (p< 0.001), ANA (p< 0.001), and anti dsDNA (p< 0.001) in SLE patients compared to apparently healthy control but the Hb is decreasing level was low in the SLE patients compared with control. In conclusion, the low hemoglobin, WBC, and ESR are non-specific parameters associated with SLE pathogenesis.    ANA, Anti-ds-DNA as excellent biomarkers for the diagnosis of SLE and serum level of TLR-7, TNF-γ, and IL-17 were evaluated in SLE patients compared to healthy people and they may be suggested as a prognostic tool in SLE patients.
