(FCI) Correlations of CD34+-cell and DC counts and days of hospitalization after PBSCT: CD34+ cell count (F), CMRF44+ DC count (G), DC1 count (H), DC2 count (I), and days of hospitalization after PBSCT. CMRF44 FITC (received as a gift from Professor DNJ Hart (Director, Mater Medical Research Institute, Raymond Terrace, Brisbane, Australia)/CD34 PE (BD Biosciences) Isotype controls Flow-Cytometry Analysis Sample analysis was carried out using a Coulter Epics-XL-MCL circulation cytometer: CD34 enumeration ISHAGE protocol, CD34+ threshold 3106 cells/kg body weight. Percentage and complete CD34+ cell counts, DC counts, and their subsets were analyzed. The graft components of all cases were analyzed for enumeration of DC figures and DC subsets through monitoring of the complete count/kilogram body weight of the parameters measured by circulation cytometry: total nucleated cells, CD34+ cells, CMRF44+ DCs, CD11c+ DCs (DC1), and CD4bright DCs (DC2). All these parameters were correlated with one another and the end result of transplantation with regard to complications, especially aGVHD and relapse.14,15 Treatment, Observation, and Follow-Up Prospective longitudinal observational follow-up of the recipients was carried out. For conditioning regimens, seven cases (24.1%) underwent minitransplantation (nonmyeloablative SCT), while 22 cases (75.9%) underwent myeloablative transplantation. All patients received main prophylaxis for aGVHD. GVHD Prophylaxis All patients received GVHD prophylaxis (calcineurin inhibitor, methotrexate, mycophenolic acid, or post-HCT cyclophosphamide). In a majority, cyclosporine (CsA) and short-course methotrexate were ent Naxagolide Hydrochloride given as GVHD prevention. Starting on day ?4, CsA was given in an intravenous dose of 2.5 mg/kg twice per day for 4 hours, then switched to an oral dose of 5 mg/kg twice daily once the mucositis was cured. The dose was modified to obtain a target level of 200C400 ng/mL after CsA levels were evaluated. On day 1, the methotrexate dose was 10 mg/m2, and on days 3, 6, and 11, the dose was 7 mg/m2. Day 6 and day 11 dosages were skipped if the mucositis was severe (grade III/IV) or bilirubin was 20 mg/L. Follow-Up All patients (recipients) were monitored for 100 days after transplantation for incidence of aGVHD, relapse, and other complications. They were assessed by clinical examination, complete blood count, blood culture, and liver and renal function. Gng11 aGVHD, relapse, and relapse-free survival were the outcomes of interest. The onset of aGVHD usually occurred during the first 2 months (60 days) following PBSCT, and systemic steroid therapy was ent Naxagolide Hydrochloride the primary line of treatment for aGVHD grade II. Staging and clinical grading for GVHD severity and response criteria were used as previously explained14,15 (as explained in Supplementary File Furniture S2 and S3). The presence of any morphological evidence of leukemia at the level of bone marrow or extramedullary sites was used to determine leukemia relapse. This was further confirmed with minimal residual disease monitoring with circulation cytometry or PCR. The period from the start of the conditioning regimen to event or final follow-up was used to assess event-free survival (EFS) (aGVHD or relapse or death). The period from the start of the conditioning regimen to death or last follow-up was defined as overall survival (OS). Recipients were then classified into three groups based on clinical end result: group I (event-free), group II (aGVHD), and group III (disease relapse). Statistical Analysis Data were collected and analyzed with SPSS 18.0. GraphPad Prism V5 was used also. Descriptive data are offered as means SD if numeric and percentages if categoric. Correlations and associations were evaluated using Spearmans rank-correlation coefficient. KaplanCMeier survival ent Naxagolide Hydrochloride curves were plotted for estimating OS, EFS, and relapse-free survival. Figures were created using GraphPad Prism 5.02). In all assessments, statistical significance was presumed at em P /em 0.05. Results ent Naxagolide Hydrochloride Kinetics and Components of the Harvests First, the kinetics and variable components of the grafts were examined. There were highly significant ( em P /em 0.001) positive correlations of CMRF44+ DC figures (median 11.88) with both DC1 (median 5.63) and DC2 (median 4.3).Moreover, a significant negative association was noted between DC figures and CD34+ cells. Interestingly, graft components showed comparable ent Naxagolide Hydrochloride CMRF44 DC, DC1, and DC2 cell figures in grafts from male and female donors (Table S4, Physique 1ACD). Supplementary Physique S1 shows graft components and their relationship to donor age and sex. Seven cases.
