  • Triggering/underlying conditions including diarrhea, vomiting, gastroenteritis, upper respiratory trait infection, and pregnancy. Good outcome includes complete remission, defined as normalization of both hematologic parameters (Ht>30%, Hb>10g/dl, LDH<460 U/L, platelets>150,000/μl) and renal function (s-creatinine<1.3 mg/dl), and partial remission, defined as normalization of hematologic parameters with renal sequelae (chronic renal failure and/or proteinuria>0.2 g/24 h). Bad outcome includes ESRF and death. Statistical analysis on CFB is not feasible because of the presence of only one CFB combined-mutated patient. Statistical analyses were performed using the chi-squared or Fisher exact test as appropriate.

  • a The number of each cell refer to the number of patients for whom each specific clinical data were available.

  • b Remission includes complete and partial remission as defined above.

  • c Graft lost for disease recurrence, rejection or other causes.
