A Prospective, Non-interventional, Observational Study of Presentation, Treatment Patterns and Outcomes in Chinese Atypical Hemolytic Uremic Syndrome Patients
This is a China, non-interventional, observational study and will follow the Good Phar-macoepidemiology Practices guidelines. This study will enrol paediatric and adult patients diagnosed with aHUS who will be treated according to routine clinical practice defined by local institutional treatment guidelines/protocol. Those aHUS patients who will be treated with a supportive therapy, which does not contain eculizumab, will be monitored for up to 12 months since the ini-tial diagnosis. Patients initiated on eculizumab treatment anytime between aHUS diagno-sis until 12 months will be followed for additional 12 months, starting from the ecu initia-tion. Patient disposition, characteristics, outcomes and safety will be described for all pa-tients enrolled into this study
