Systemic Lupus Erythematosus (SLE) and systemic sclerosis (SSc) are systemic inflammatory autoimmune disorders characterized by a large spectrum of clinical and laboratory features. The aim of the present study was to investigate the possible use of serum level of soluble intercellular adhesion molecule-1(sICAM-1) and soluble interleukin-2 receptor (sIL-2Ra) as biomarkers for monitoring of SLE and SSc disease activity. Moreover, it aimed to compare the specificity and sensitivity as well as cut-off value of both biomarkers in a sample of Egyptian patients. 50 SLE patients, 30 SSc patients and 60 age and sex matched healthy controls were enrolled in our study. sICAM-1and sIL-2Ra were measured in serum samples obtained from all participants. In addition to Erythosedimentation rate (ESR), complete blood count (CBC), Antineuclearantibodies (ANA) estimation, disease activity of both diseases were also assessed. sICAM-1and sIL-2Ra levels were higher in SLE and SSc patients versus control. Both parameters are correlated with each other as well as the activity parameters. A cut-off levels of 455.59 (ng/ml) &2525935 (pg/ml) in both SLE & SSs respectively was observed with the highest specificity and sensitivity. It could be concluded that sICAM-1 and sIL-2Ra are noninvasive biomarkers for SLE and SSc that could play a pathophysiologic role in development and progression of both diseases. Moreover, sICAM-1 and sIL-2Ra are correlated with the disease activity at cut-off values of 455.59 (ng/ml) & 2525935(pg/ml) respectively. https://biomedpharmajournal.org/vol12no3/biomarkers-of-systemic-lupus-erythematosus-and-systemic-sclerosis-diseases-activity-in-a-sample-of-egyptian-patients-soluble-intercellular-adhesion-molecule-1-and-soluble-interleukin-2-receptor-cas/ Soluble Intracellular Adhesion Molecule-1 Soluble Interleukin 2 Receptor Systemic Lupus Erythematosus Systemic Sclerosis
