♦ Background: Patients with end-stage renal failure (ESRF) need integrated health care to maintain a desirable quality of life. Studies suggest that post-discharge nurseled telephone support has a positive effect for patients suffering from chronic diseases. But the post-discharge care is under-developed in mainland China and the effects of post-discharge care on patients with peritoneal dialysis have not been conclusive. ♦ Aim: The purpose of this study is to test the effectiveness of postdischarge nurse-led telephone support on patients with peritoneal dialysis in mainland China. ♦ Methods: A randomized controlled trial was conducted in the medical department of a regional hospital in Guangzhou. 135 patients were recruited, 69 in the study group and 66 in the control group. The control group received routine hospital discharge care. The study group received post-discharge nurse-led telephone support. The quality of life (Kidney Disease Quality of Life Short Form, KDQOL-SF), blood chemistry, complication control, readmission and clinic visit rates were observed at three time intervals: baseline before discharge (T1), 6 (T2) and 12 (T3) weeks after discharge. ♦ Results: Statistically significant effects were found for symptom/problem, work status, staff encouragement, patient satisfaction and energy/fatigue in KDQOL-SF and 84-day (12-week) clinic visit rates between the two groups. The study group had more significant improvement than the control group for sleep, staff encouragement at both T2 and T3, and pain at T2 and patient satisfaction at T3. No significant differences were observed between the two groups for the baseline measures, other dimensions in KDQOL-SF, blood chemistry, complication control, readmission rates at all time intervals and clinic visit rates at the first two time intervals. ♦ Conclusions: Post-discharge nurse-led telephone support for patients undergoing peritoneal dialysis is effective to enhance patients' well-being in the transition from hospital to home in mainland China.

Selectin-selectin ligand interactions mediate the initial steps in leukocyte migration, an integral part of immune responses. Fucosyltransferase-VII (FucT-VII), encoded by Fut7, is essential for biosynthesis of selectin ligands. In an established model of cardiac allograft vasculopathy and chronic rejection, Fut7 −/− recipients exhibited long-term graft survival with minimal vasculopathy compared with WT controls. Graft survival was associated with CD4 T-cell exhaustion in the periphery, characterized by impaired effector cytokine production, defective proliferation, increased expression of inhibitory receptors programmed death-1 (PD-1) and T cell Ig-and mucin-domain-containing molecule-3 (Tim-3), low levels of IL-7Rα on CD4 T cells, and reduced migration of polyfunctional CD4 memory T cells to the allograft. Blocking PD-1 triggered rejection only in Fut7 −/− recipients, whereas depleting regulatory T cells had no effect in either Fut7 −/− or WT recipients. Adoptive transfer experiments confirmed that this CD4 T cell-exhausted phenotype is seen primarily in Fut7 −/− CD4 T cells. These data suggest that impaired leukocyte recruitment is a novel mechanism leading to CD4 T-cell exhaustion. Our experimental system serves as an excellent model to study CD4 T-cell exhaustion as a dominant mechanism of transplant tolerance. Further, targeting FucT-VII may serve as a promising strategy to prevent chronic allograft rejection and promote tolerance.adhesion | traffic | apoptosis
