Search for: [Abstract = "\+30 after transplantation and engraftment \(n=10\),• correlation between C3 and C4 concentrations and clinical follow\-up after transplantation including posttransplant complications \(n=73\).Following conclusions were supported by the results\:1. The optimal hematopoietic stem cell mobilization was observed after 5 days G\-CSF administration \(leukocytosis, amount of c\-kit\+\/Thy\-1\+ cells in mice\).2. The use of C3a antagonist was related to the increase of stem cell amount after 5 days mobilization with G\-CSF and was independent on the antagonist’s dose.3. No simple correlation between C3\/C4 concentrations in the first 30 days after transplantation and engraftment was found.4. Statistical relevance \(p=0,0403\) of higher incidence of quiescent cGvHD in maximal 2 organs in children with abnormal C3\/C4 concentrations during 3\-year\-follow\-up after transplantation was shown. \; 5. There was no statistical relevance of\: patient’s sex and age, clinical diagnosis, type of donor, source of stem cells, type of conditioning therapy, in vivo\/ex vivo lymphocyte depletion, GvHD prophylaxis, aGvHD incidence and staging, cGvHD occurrence, sepsis, virus reactivation \(CMV, EBV, ADV\), mycosis, VOD or survival rate in a group of children with abnormal C3\/C4 concentrations after transplantation.These findings imply minor clinical importance of complement disorders in the post\-transplant follow\-up in children."]
