The present study aims to: Compare clinical features, hematological indices and disease activity between the early-onset and late-onset patients with systemic lupus erythematosus. Evaluate the relationship between hematological indices (mean platelet volume, platelet lymphocyte ratio and neutrophil lymphocyte ratio) and Systemic lupus erythematosus (SLE) disease manifestations and activity.
This is a cross sectional study, patients with SLE will be gathered from the Internal medicine department and Rheumatology and Immunology outpatient clinic in Sohag university hospital. All patients fulfilled 2019 European League Against Rheumatism/American College of Rheumatology classification criteria for systemic lupus erythematosus. In this study, 100 SLE patients will be classified into two groups: Group A: early onset SLE (age at diagnosis \< 50 years). Group B: late onset SLE. (age at diagnosis ≥ 50 Data collection procedure: The following clinical data will be collected: Clinical assessment: Name, age, gender, smoker or ex-smoker or non-smoker, blood pressure and body mass index. Clinical manifestations as: Malar rash. Discoid rash. Photosensitivity. Mucocutaneous or oral ulcer. Alopecia. Raynaud's phenomena. History of deep venous thrombosis. Cutaneous vasculitis. Fever. Lupus nephritis. Arthritis. Myositis. Secondary antiphospholipid syndrome. Serositis. Pleural effusion. Renal manifestations (puffiness and lower limb edema). Neurological (headache, seizers, psychosis and Disturbed conscious level) Hematological manifestations: Thrombocytopenia (bleeding tendency) Anemia and Hemolytic anemia (anemic manifestation). Hypertension. Diabetes mellitus. Previous coronary event or Peripheral vascular disease. Laboratory assessment: 1. CBC with differential WBCs count. 2. Antinuclear Antibody tests (ANA). 3. Anti-double-stranded DNA (ds DNA). 4. Anti-Sm. 5. C3 and C4 complement level. 6. Serum creatinine level. 7. Anti phospholipid marker (if needed). Each clinical data and laboratory results will be put into the SLEDAI score. The score is considered accurate and reliable. Categories of disease activity based on SLEDAI scores are as follows: no activity (SLEDAI= 0), mild activity (SLEDAI= 1-5), moderate activity (SLEDAI= 6-10), high activity (SLEDAI= 11-19) and very high activity (SLEDAI= 20). The present study aims to: Compare clinical features, and disease activity as SLEDAI score between the early-onset and late-onset patients with systemic lupus erythematosus. Evaluate the relationship between hematological indices (mean platelet volume, platelet lymphocyte ratio and neutrophil lymphocyte ratio) and Systemic lupus erythematosus (SLE) disease manifestations and activity Duration of study: Six months after approval of the protocol by Medical Research Ethics Committee of Sohag faculty of medicine. Inclusion criteria: All patients fulfilled 2019 European League Against Rheumatism/American College of Rheumatology classification criteria for systemic lupus erythematosus. Exclusion Criteria: Patients received glucocorticoid or immunosuppressant medication. Patients presented with other chronic inflammatory diseases, infection, or other autoimmune diseases at the time of diagnosis Malignancy Pregnancy.

Is used to detect haematological indices (mean platelet volume, platelet lymphocyte ratio and neutrophil lymphocyte ratio) and its relation to disease activity

Evaluate the hematological indices as (mean platelet volume) of our SLE patient.
Neutrophils, lymphocytes, and platelets play important roles in the course of various diseases . In recent years, there has been a growing interest in the role of hematological indices (mean platelet volume, platelet lymphocyte ratio and neutrophil lymphocyte ratio) to estimate disease activity in some auto-immune diseases as and SLE . Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), as CBC parameters, have recently shown to be useful markers of inflammation in autoimmune and inflammatory disorders so we will do CBC for our pt to detect mean platelet volume
Time frame: for 2 weeks after admission of patient in sohag university hospital]

As method of detection of acute acivity of SLE
To detect antiphospholipid syndrome if there is sign of thrombosis
To detct complication of disease on kidney
Is criteria of diagnosis of SLE
Is score to detect the activity of disease
Compare the degree of disease activity between the early-onset and late-onset patients with systemic lupus erythematosus.
Each clinical data and laboratory results will be put into the SLEDAI score. The score is considered accurate and reliable. Categories of disease activity based on SLEDAI scores are as follows: no activity (SLEDAI= 0), mild activity (SLEDAI= 1-5), moderate activity (SLEDAI= 6-10), high activity (SLEDAI= 11-19) and very high activity (SLEDAI= 20).
Time frame: for 2 weeks after admission of patient in sohag university hospital]
Evaluate the correlation between hematological indices (mean platelet volume, platelet lymphocyte ratio and neutrophil lymphocyte ratio) and Systemic lupus erythematosus (SLE) disease manifestations and activity.
After detection of previous outcome \[ disease activity , clinical feature,haematological indices \] we will compare them to detect the correlation between them for every patient
