|Condition or disease||Intervention/treatment||Phase|
|Atypical Hemolytic Uremic Syndrome||Drug: eculizumab||Phase 4|
A visit (physical examination; blood pressure measurement) will be performed every month for 3 months, and every 3 months for 21 months.
Blood (serum creatinine, platelet count, hemoglobin, LDH, haptoglobin) and urine (proteinuria/creatininuria ratio and microscopic hematuria) tests will be performed every 2 weeks from inclusion to M6 and subsequently every month starting M7 Urine dipstick (for albuminuria and microscopic hematuria) will be performed by the patients at home at least twice a week.
Markers of complement activation and biomarkers of endothelial cells activation and immune cells activation will be assessed at baseline, M1, M3, M6, M9, M12, M18 and M24.

- The incidence of aHUS relapse during 2 years of follow-up after eculizumab discontinuation [ Time Frame: 24 months ]
aHUS relapse will be defined by the coexistence of at least two of the following:
- thrombocytopenia (platelet count < 150 G/L),
- mechanical hemolytical anaemia (Hb < 10 g/dl, LDH > upper limit of normal, undetectable haptoglobin, presence of schizocytes on blood smear),
- acute kidney injury (serum creatinine and/or proteinuria/creatininuria > upper limit of normal for age or an increase > 15% compared to baseline levels ),
- features of thrombotic microangiopathy (glomerular and/or arteriolar thrombi, doubles contours, endothelial cells detachment) in a kidney biopsy, if performed.
