These deposits are Congo red-negative, have hollow centers, measure > 30 nm, and are arranged in stacked or parallel arrays. Treatment of immunotactoid glomerulonephritis is not well-defined, with poor outcomes seen in native kidneys. In fewer than 10% of the cases, trials with steroids alone or cytotoxic agents with steroids or plasmapheresis with steroids has been associated with clinical remission of proteinuria. 50% of patients with renal impairment progress to end stage renal disease (ESRD) in two to four years. There are three case reports of recurrent ITG in renal allograft;one was treated with pulse steroids plus cyclophosphamide, pulse steroids in second case and use of rituximab in the third case. Recurrence of ITG has been described in the renal allograft but there is no literature on relapse of ITG in the native kidneys. Here, we have a case of ITG that relapsed in the native kidneys eight years after being in remission. Renal function improved with fludarabine both times and the patient had stable renal function at last follow-up.展开更多

We assessed fludarabine and cytarabine with transfusion of donor haematopoietic stem cell in treating the relapse of acute leukaemia after allo-HSCT. Methods Seven patients, median age 34 years, with relapse of acute leukaemia after allo-HSCT received combination chemotherapy of fludarabine with cytarabine for 5 days. Five patients suffered from acute myeloid leukaemia （2 refractory） and 2 refractory acute lymphoblastic leukaemia. After the transplantation, the median relapse time was 110 days （range, 38-185 days）. Two days after chemotherapy, 5 patients received infusion of donor＇s peripheral blood stem cells, mobilized by granulocyte colony stimulating factor. No prophylactic agents of graft versus host diseases were administered, Results Six patients achieved haematopoietic reconstitution. DNA sequence analysis at day 30 after treatment identified all as full donor chimera type. The median observation time was 189 days. After the treatment, the median time for neutrophilic granulocyte value 〉0.5×10^9/L and for platelet value 〉20×10^9/L were 13 days （range, 10-18 days） and 15 days （range, 11-24 days）, respectively. Graft versus host disease occurred in 2 patients （acute） and 3 （chronic）. Five patients suffered from pulmonary fungal infection （2 died）, 3 haemorrhagic cystitis and 2 cytomegalovirus viraemia. The other patients died of leukaemia related deaths. Three patients with chronic graft versus host disease who had received donor peripheral blood stem cells reinfusion have survived for 375 days, 232 days and 195 days, respectively. Conclusions Fludarabine with cytarabine plus the donor haematopoietic stem cell should be considered as an effective therapeutic regimen for relapse of acute leukaemia after alIo-HSCT. The disease free state of patients may increase, though with high risk of secondary fungal infection.展开更多
