Primary immune thrombocytopenia (ITP) is an autoimmune- mediated acquired bleeding disorder, defined as a platelet count less than 100×109/L without other causes of isolated thrombocytopenia. The etiology of ITP is complex and heterogeneous, and as no specific biomarkers are indicating its presence, ITP remains a diagnosis of exclusion. The heterogeneous nature of ITP is evident in the differences in clinical presentation and response to regular treatment among patients and the multiple mechanisms that have been forwarded to account for it, such as autoantibodies, T cell dysregulation, and impaired megakaryocytes. Except primary ITP, all forms of immune-mediated thrombocytopenia is defined as secondary ITP. Secondary ITP has several causes, including autoimmune diseases such as systemic lupus erythematosus

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
1. To evaluate and compare the expression levels of IL-1β and IL-33 in patients with primary ITP and those with SLE-associated thrombocytopenia
Timeframe: January 2026 to August 2026
2. To correlate cytokine expression levels with platelet counts and disease activity scores.
Timeframe: January 2026 to August 2026
3. To assess the potential of IL-1β and IL-33 as diagnostic biomarkers for differentiating ITP from SLE-thrombocytopenia.
Timeframe: June 2026 to august 2026
