Between April 1996 and May 1998, 20 consecutive patients with Ph chromosome-positive CML in first chronic phase without an HLA-identical sibling received the mini-ICE regimen shortly after diagnosis to mobilize progenitor cells into the peripheral blood (PBPCs). The sex distribution was 12 males and eight females and the median (range) age 48.5 (22-62) years. The time interval between diagnosis and mobilization was a median (range) of 2 (0-5) months. Leukaphereses were initiated during recovery from chemotherapy-induced aplasia. A median number of 3 (1-7) aphereses per patient were performed to collect >/=2.0 x 106 CD34+cells/kg. Cytogenetic analysis was performed on the aphereses products of 18 patients. Complete cytogenetic Ph chromosome negativity was observed in four patients, nine had a partial negativity, three a minimal negativity and two no negative cells. Southern blot for bcr-abl was negative in the remaining two patients but the polymerase chain reaction analysis was positive. Following reinfusion, severe neutropenia was present for a median of 8.5 (3-19) days and severe thrombocytopenia lasted a median of 8 (3-18) days. Ten patients did not develop febrile neutropenia with four of them being treated on an outpatient basis. Treatment-related mortality was not observed. In conclusion, our experience demonstrates the feasibility of mobilizing PBPCs shortly after the diagnosis of CML with a safe regimen. Of note, mini-ICE allowed the collection of apheresis products with at least a major component of Ph-negative cells in almost 75% of the patients.

The trisomy of human chromosome 21 (Down syndrome) is the leading genetic cause of learning difficulties in children, and predisposes this population to the early onset of the neurodegeneration of Alzheimer's disease. Down syndrome is associated with increased interferon (IFN) sensitivity resulting in unexpectedly high levels of IFN inducible gene products including Fas, complement factor C3, and neuronal HLA I which could result in a damaging inflammatory reaction in the brain. Consistent with this possibility, we report here that the trisomy 16 mouse fetus has significantly increased whole brain IFN-gamma and Fas receptor immunoreactivity and that cultured whole brain trisomy 16 mouse neurons have increased basal levels of caspase 1 activity and altered homeostasis of intracellular calcium and pH. The trisomic neurons also showed a heightened sensitivity to the increase in both Fas receptor levels and caspase 1 activity we observed when IFN-gamma was added to the neuron culture media. Because of the autoregulatory nature of IFN activity, and the IFN inducing capability of caspase-1-activated cytokine activity, our data argue in favor of the possibility of an interferon-mediated, self-perpetuating, inflammatory response in the trisomy brain that could subserve the loss of neuron viability seen in this trisomy 16 mouse model for Down syndrome.

For most chronic myeloid leukaemia patients the option of a potentially curative allogeneic stem cell transplantation is not available because of age or lack of donor. Alternative therapy with interferon-alpha appears to prolong survival but is probably not curative. The aim of the study is to analyse the clinical results of the first Hungarian autologous transplantations in CML. METHODS: Seven patients were treated with ICE-based regimen plus G-CSF with the aim of mobilising and collecting Ph-negative peripheral stem cells in the setting of autologous transplant program. Five patients had CML in first chronic phase and two in accelerated phase. All patients have been previously treated with interferon-alpha. RESULTS: Median value and ranges for harvested mononuclear cells, CD34(+) cells and CFU-GM were: 5.65x10(8)/kg (2.61-11.38), 1.48x10(6)/kg (0.216-3.5) and 3.43x10(4)/kg (0.243-11.6), respectively. Four out of seven autologous grafts have been transplanted. Busulfan conditioning was used in one case and TBI/Cy conditioning in three patients. All patients are alive and well post-transplant being on interferon-alpha therapy. CONCLUSIONS: Based on the clinical advantages of autologous transplantation including long-term chronic phase, achievement of second chronic phase and improved response to interferon-alpha therapy, the procedure can offer an alternative treatment in CML in lack of HLA-identical donor.

Although childhood acute lymphoblastic leukemias are of good prognosis than leukemias of adulthood, some chromosomal abnormalities may have negative effects on their prognosis. Inverted duplication (1q) is a chromosomal abnormality with negative effect on outcome of Burkitt leukemia and lymphomas. We report a case of CD20 Burkitt leukemia with inverted duplication (1q) mutation, who had an early relapse during NHL-BFM 95 treatment. Two courses of ICE-rituximab treatment were administered after relapse and a successful HLA-full match bone marrow transplantation was carried out. He is in follow-up for 18 months without any problem after the bone marrow transplantation. We suggest the usage of ICE protocol combined with rituximab in childhood CD20 Burkitt leukemia with poor prognostic criteria such as inverted duplication (1q) mutation.
