Patients are numbered according to an individual number. For P8 it was not possible to obtain clinical features. Explanation of the clinical features: ‘Triggers’: 1 indicates no trigger; 2 flulike, gastroenteritis, other infections; 3 pregnancy; 4 unknown. ‘Biochemical analysis’: (↓) indicates low values; N/A not available; normal values C3: 0.90 – 1.80 g/l; normal values C4: 0.15 – 0.45 g/l; normal levels sC5b-9: <1.0 AU/ml. ‘Treatment’: 1 indicates plasma, supportive treatment and drugs acting on immune system; 2 plasmapheresis, infusion or exchange; 3 plasma and drugs acting on both coagulation cascade and immune system; 4 unknown. ‘Outcome’: 1 indicates ESRF; 2 partial remission; 3 complete remission. ‘Transplantation history’: 1 indicates disease recurrence in graft; 2 good renal function at 1 year.
