- To specify incidence and risk factors for secondary autoimmune diseases (AD) after HSCT for a primary AD, we retrospectively analysed AD patients treated by HSCT reported to EBMT from 1995 to 2009 with at least one secondary AD (cases) and those without (controls). After autologous HSCT, 29 amongst 347 patients developed at least one secondary AD within 21.9 (0.6-49) months and after allogeneic HSCT, 3 amongst 16 patients. The observed secondary AD included: autoimmune hemolytic anemia (n=3), acquired haemophilia (n=3), autoimmune thrombocytopenia (n=3), antiphospholipid syndrome (n=2), thyroiditis (n=12), blocking TSHR-ab (n=1), Graves' disease (n=2), myasthenia gravis (n=1), rheumatoid arthritis (n=2), sarcoidosis (n=2), vasculitis (n=1), psoriasis (n=1) and psoriatic arthritis (n=1). After autologous HSCT for primary AD, the cumulative incidence of secondary AD was 9.8+/-2 % at 5 years, lupus erythematosus as primary AD and antithymocyte-globulin use plus CD34+ graft selection were important risk factors for secondary AD by multivariate analysis. With a median follow-up of 6.2 (0.54-11) years after autologous HSCT, 26/29 patients with secondary AD were alive, 2 died during their secondary AD (antiphospholipid syndrome, haemophilia) and 1 death was HSCT related. This European multicenter study underlines the need for careful management and follow-up for secondary AD after HSCT.

- Pediatric patients with refractory or relapsed metastatic neuroblastoma (NBL) have a poor prognosis despite autologous stem cell transplantation (SCT). Allogeneic SCT from a haploidentical donor has a remarkable alloreactive effect in patients with leukemia; thus, we evaluated this approach in children with very high-risk NBL. We analyzed data from 2 prospective phase I/II trials. A total of 26 patients with refractory (n = 5), metastatic relapsed (n = 20), or locally relapsed MYCN-positive (n = 1) NBL received a median of 17 × 106/kg T/B cell-depleted CD34+ stem cells with 68 × 103/kg residual T cells and 107 × 106/kg natural killer cells. The conditioning regimen comprised melphalan, fludarabine, thiotepa, OKT3, and a short course of mycophenolate mofetil post-transplantation. Engraftment occurred in 96% of the patients. Event-free survival and overall survival at 5 years were 19% and 23%, respectively. No transplantation-related mortality was observed, and the single death was due to progression/subsequent relapse. The median duration of follow-up was 8.1 years. Patients in complete remission before SCT had a significantly better prognosis than those with residual tumor load (P < .01). All patients with progressive disease before SCT relapsed within 1 year. Grade II and grade III acute graft-versus-host disease (GVHD) occurred in 31% and 12% of the patients, respectively. Chronic limited and extensive GVHD occurred in 28% and 10%, respectively. Our data indicate that haploidentical SCT is a feasible treatment option that can induce long-term remission in some patients with NBL with tolerable side effects, and may enable the development of further post-transplantation therapeutic strategies based on the donor-derived immune system.
