What this trial studies

This observational study aims to create a prospective cohort registry for patients diagnosed with acquired and congenital Thrombotic Thrombocytopenic Purpura (TTP). It will investigate the disease's prevalence, course, treatment success, and potential triggers for relapses while also focusing on identifying predictive markers for morbidity and mortality. The study will collect clinical and laboratory data to enhance understanding of TTP and improve diagnostic and therapeutic approaches. Participants will be followed over time to assess long-term outcomes and therapy responses.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with clinically diagnosed acquired or congenital TTP.

Not a fit: Patients who cannot communicate effectively or do not understand German or English may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and treatment strategies for patients with TTP.

How similar studies have performed: While observational studies on TTP exist, this registry approach may provide novel insights into the disease's management and outcomes.
