Brief summary

Primary objective \- To determine the clinical prognosis by identifying the disease course and severity by treatment with or without eculizumab in patients with aHUS in Korea. Secondary objectives * To determine the clinical prognosis of the disease in all patients with aHUS in Korea. * To determine the clinical prognosis of the disease in patients diagnosed with aHUS prior to the initiation of eculizumab reimbursement system in Korea. * To determine the treatment responses by treatment options in patients with aHUS in Korea. * To identify risk factors that affect mortality in all patients with aHUS in Korea. * To investigate the recurrence and clinical prognosis in patients with aHUS in Korea when eculizumab is discontinued

Design outcomes

Primary

Measure	Time frame	Description
Clinical prognosis (Renal survival) by treatment with or without eculizumab	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, or date of ESRD diagnosis, whichever came first	Renal survival (end-stage renal disease \[ESRD\]-free survival)
Clinical prognosis (Overall survival) by treatment with or without eculizumab	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, whichever came first	Overall survival (OS)

Secondary

Measure	Time frame	Description
Clinical prognosis (Renal survival) of patients diagnosed with aHUS prior to the initiation of eculizumab reimbursement system in Korea	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, or date of ESRD diagnosis, whichever came first	Renal survival (ESRD-free survival)
Clinical prognosis (Renal survival) of all aHUS patients in Korea	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, or date of ESRD diagnosis, whichever came first	Renal survival (ESRD-free survival)
Response rates of each treatment, compared to prior to start treatment	3rd and 6th months	Complete response of TMA
Clinical prognosis (Overall survival) of patients diagnosed with aHUS prior to the initiation of eculizumab reimbursement system in Korea	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, whichever came first	Overall survival (OS)
Clinical prognosis (Overall survival) of all aHUS patients in Korea	from the first onset date of TMA diagnosed as aHUS to the last follow up (within March 31, 2022), death, whichever came first	Overall survival (OS)
