Eligibility
Inclusion criteria
Inclusion criteria: 1. patients of any age with aHUS diagnosed by a medical professional at any age (first episode or recurrence). 2. Evidence of TMA, including thrombocytopenia, evidence of haemolysis, and renal dysfunction, should be documented over a 1-week period based on the following laboratory findings: (1) platelet count =1.5 × upper limit of normal (ULN), haemoglobin = ULN in adult patients (>= 18 years of age) or >= 97.5% of the upper limit of normal (ULN) for the age group in which they are enrolled in paediatric patients (patients with acute kidney injury requiring dialysis are also eligible). 3. Male and/or female. 4. able to provide signed informed consent or consent as described in Appendix 6.2.1, which includes compliance with the requirements and limitations outlined in the Intelligent Consent Form (ICF) and in this protocol.
Exclusion criteria
Exclusion criteria: 1.Patients diagnosed with HUS+ due to infection with Shiga toxin-producing Escherichia coli (STEC). 2.Patients with a clear diagnosis of TTP who exhibit ADAMTS13 activity of less than 10%. 3.A written informed consent form cannot be provided. 4.The researchers believe that any medical or psychological conditions the patient may have could potentially increase their risk of participating in the study or interfere with the study’s outcome.
