ITP Registry and Accompanying Biospecimen Collection

Immune thrombocytopenia (ITP) is a rare hematologic disorder that can lead to a greater risk of bleeding or a prolonged bleeding time due to an autoimmune-mediated deficiency of platelets.

In recent years, new treatment options for patients with immune thrombocytopenia have emerged.

The results of published clinical studies on ITP can only be used for broad patient care to a limited extent, as they are designed for a patient population with clearly defined inclusion and exclusion criteria. Real world data collected from this registry will help to better understand the diagnosis and therapy of ITP patients in everyday treatment and to more effectively direct individual patients to optimal therapy, thus improving their outcomes.

By collecting biospecimens, this project will contribute new knowledge to the study of ITP through standardized, systematic, and high-quality collection and storage of patient samples and associated data.

The registry collects clinical data from patients diagnosed with ITP at defined points in the course of the disease. The Data collection includes a range of clinical measures, disease-related factors, treatment/treatment course and outcomes, complications during treatment and Qol, fatigue scoring and survival data (up to 5 years).

The data are collected prospectively. In addition, patients can be included retrospectively up to 12 months after the initial diagnosis if continuous documentation can be provided at the treatment centre. In both cases, a written declaration of consent is obligatory.

Inclusion criteria

• Primary or secondary Immune Thrombocytopenia (ITP)
• Age ≥18 years
• signed declaration of consent

Exclusion criteria

• diagnoses that cannot be reconciled with the diagnosis of ITP (esp. heparin-induced thrombocytopenia, pregnancy-associated thrombocytopenia, pseudothrombocytopenia)
• no informed consent possible (this covers patients who are unable to understand the nature and scope of participation)
