Primary immune thrombocytopenia (PIT), formerly known as idiopathic thrombocytopenic purpura, is a condition where the body destroys platelets faster than they are produced, leading to low platelet counts. The causes of PIT are not well understood, and patients show a wide range of symptoms and treatments. Diagnosis is typically made by ruling out other causes of low platelet counts. Due to limited data on how common PIT is, especially in Spain, this study aims to improve knowledge about the disease and better describe the characteristics of patients with PIT and other immune thrombocytopenias in Spain. This epidemiological study is ambispective and involves multiple hospitals in Spain. It collects information from patients' medical records about their disease and treatments since 2015. The study includes children as young as 2 months and adults who have been followed since 2015, regardless of when they were diagnosed. For deceased patients after December 31, 2015, data will still be included even if informed consent cannot be obtained. Participants contribute data from their clinical history for analysis. Researchers will describe the clinical and laboratory features of PIT and other immune thrombocytopenias starting from enrollment. The study monitors patient information to better understand the disease and its management. There are no specific treatment interventions or procedures since this is an observational registry study.
