5 and 78 months, respectively. Obesity according BMI, WHR, and VFA was diagnosed in 49.7%, 45.0%, and 44.5% of patients, respectively. The median value of BFM, FFM, VFA, and TSFA and the mean value of PBF were 19.3 kg, 55 kg, 93.2 cm2, 24.9 kg, and 27.3%, respectively. We found significant positive correlations among WHR, VFA, baPWV right, baPWV left, and cfPWV. Conclusions Obesity and visceral fat tissue influence on arterial stiffness. The analysis of magnitude of obesity and body fat tissue parameters can be used as an additional cardiovascular risk factor in RTrs.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective measure for the treatment of severe aplastic anemia (SAA). While infection, graft failure, and graft-vs-host disease (GVHD) are the main causes of allo-HSCT failure, a second HSCT is needed to eliminate the dependence of blood transfusion and maintain disease-free survival. We applied low-dose total body irradiation (TBI) + fludarabine (FLU) + cyclophosphamide (CTX) + antilymphocyte globulin (ALG) + busulfan (BU) as a conditioning regimen of second HSCT after a transplantation with an HLA-mismatched donor. As for retransplantation donors, 1 child had an unrelated HLA-matched donor, and 2 children had related HLA-mismatched ones. The latter underwent more serious GVHD with a relatively high cytokine level, and the former had no obvious GVHD after the second HSCT. All 3 patients achieved a desirable effect within 1 month and received satisfactory therapeutic effect during the subsequent follow-up, indicating the convincing effectiveness and safety of this method.Data binding the expression of Toll-like 4 receptor (TLR4), transplanted kidney (KT) function, and symptomatic CMV infection (CMV+) are scarcely available. Objective To investigate the relationship between TLR4 expression (TLR4ex) in patients who had a relapse of CMV and transplant function. Materials and methods TLR4ex was measured in peripheral blood mononuclear cells of KT recipients. We compared TLR4ex among 30 CMV+ patients and 87 patients without CMV infection (CMVneg). At the beginning (day 0) TLR4ex, as well as concentrations of cyclosporin A and tacrolimus were determined. All patients, CMV+ and CMVneg patients were divided according to the respective median of TLR4ex into groups of low-TLR4 expression (L-TLR4ex) and high-TLR4 expression (H-TLR4ex). Estimated glomerular filtration rate (EGFR) was assessed on day 0 and after the follow-up (F-up). The magnitudes of EGFR change (ΔEGFR) were evaluated. Stable treatment along the F-up period (median 11.9 months) was applied. Results TLR4ex of CMV+ in 67% was below median for all patients. For day 0, in CMV+ no link of TLR4ex with EGFR was found; TLR4ex was lower but day 0 EGFR did not differ from H-TLR4ex. In CMVneg, a GFR-TLR4ex link was present. Post F-up. In CMV+ with L-TLR4ex, EGFR declined, with no change in H-TLR4ex. In CMVneg with H-TLR4ex, EGFR increased, with no change in L-TLR4ex. Both regression and receiver operating characteristic curve analyses points out the impact of CMV+ and TLR4ex on eGFR and ΔEGFR. Conclusion In CMV+, low TLR4ex increases the risk of EGFR deterioration. In CMVneg, high TLR4ex raises the chance of EGFR improvement.Background Neutrophils play an important role in xenogeneic rejection and represent a major obstacle in clinical application of xenografts. CD200 and its receptor CD200R are both type-1 membrane glycoproteins, which are members of the immunoglobulin superfamily (IgSF) and the ligation of CD200 with CD200R induces inhibitory NPXY signaling. The expression of CD200R appears in myeloid cells such as macrophages and granulocytes. Thus, we hypothesized that human CD200 expression on porcine cells might suppress the xenogeneic neutrophil-mediated cytotoxicity against porcine cells. Methods To prove our hypothesis, the suppressive effect of human CD200 in neutrophil-like human cell line 60 (HL-60)-mediated xenogeneic cytotoxicity against swine endothelial cells (SECs) was examined. Cytotoxicity was assessed with water-soluble tetrazolium salt 8 (WST-8) assay. Results HL-60 cells differentiated into CD66b+ CD200R+ neutrophil-like cells in the presence of dimethyl sulfoxide (DMSO). HL-60-mediated cytotoxicity against SECs was significantly suppressed by human CD200 on SECs. Conclusions The findings in this study indicate that human CD200 may suppress neutrophil-mediated xenogeneic rejection.Outcomes of pregnancies after kidney transplantation were evaluated. Thirty-one pregnancies in 26 women were noted. The mean maternal age at pregnancy was 31 ± 5 years (range, 23-44 years). The interval between transplantation and conception was 54 ± 51 months (range, 7-213 months). The mean serum creatinine concentration before conception was 1.28 ± 0.4 mg/dL (range, 0.8-2.45 mg/dL), and mean estimated glomerular filtration rate (Chronic Kidney Disease Epidemiology Collaboration) was 62 ± 18 mL/min/1.73 m2 (range, 27-106 mL/min/1.73 m2). There were no maternal deaths. There was 1 case of suspected acute rejection after delivery. There was 1 case of graft loss during pregnancy. Maternal complications included edema (6/26), hypertension (7/26), increase of (2/26) or appearance of proteinuria (5/26), and preeclampsia (4/26). Idasanutlin Mean creatinine increase during pregnancy was 0.02 mg/dL. Mean creatinine 1 year after pregnancy was 1.54 mg/dL (±0.8 mg/dL). There were 19 cesarean sections. Fetal outcomes included 25 live births, 4 abortions, and 2 stillbirths. Out of 25 live births, 22 children were considered healthy, 2 children had congenital defects, and there were 2 deaths at neonatal age. Mean pregnancy age was 35 ± 4 weeks (range, 24-40 weeks). The rate of premature deliveries was 15 of 25. Mean neonate birth weight was 2363 ± 1029 grams (range, 490-4100 grams). The rate of babies small for gestational age was 19%. During follow-up (range, 0.5-30 years) 5 of 26 patients lost grafts (between 3 and 15 years after pregnancy); most (20) of the children previously considered healthy had good long-term development. Our results confirm that risk of pregnancy in kidney transplant recipients can be accepted, and children considered healthy at delivery develop well.
