Objective It remains debated whether reduced doses of chronic calcineurin inhibitors benefit graft survival. Methods This retrospective study analyzed 60 first cadaveric renal transplant recipients who received cyclosporine (CSA), mycophenolate mofetil (MMF) and prednisone (CMP group) and 71 recipients who received reduced-dose CSA with prednisone and MMF (RCMP group). All recipients were followed for at least 96 months. The Modification of Diet in Renal Disease (MDRD) glomerular filtration rate (GFR) calculated at different time points, graft survival, the incidence of chronic allograft nephropathy (CAN) and the acute rejection rate within six months were analyzed and compared between the two groups. Results The incidence of acute rejection within six months post-transplant was 15.5% (11/71) in the RCMP group and 13.3% (8/60) in the CMP group. This difference was not significant (p=0.727). The MDRDcalculated GFR in the CMP group reached a peak at 24 months post-transplant (66.6±20.2 mL/min/1.73 m2) then decreased gradually. In contrast, in the RCMP group, the GFR reached a peak at 36 months posttransplant (76.9±19.6 mL/min/1.73 m2). The GFR from month 36 to month 96 was significantly higher in the RCMP group than in the CMP group. The Kaplan-Meier calculated death-censored graft survival in the RCMP group was significantly higher than that observed in the CMP group, with an estimated cumulative proportion surviving at 96 months of 95.5% in the RCMP group and 83.5% in the CMP group. The incidence of CAN within 96 months was 5.6% (4/71) in the RCMP group vs. 16.7% (10/60) in the CMP group (p=0.042). Conclusion An RCMP regimen can significantly improve the long-term GFR level and benefit graft survival. © 2013 The Japanese Society of Internal Medicine. Source

IgA nephropathy(IgAN) is the most common primary glomerular disease in China. Primary infections always occur before IgAN. However, the pathology of IgAN is still unclear. Previously we found that LL37, a protein secreted by senescent cells, was specific for the progression of IgAN, and also played a role in the neutrophil function. So we hypothesized that the infiltration of neutrophils, inflammation factors, and aging markers, which were modulated by functional networks, induced the immune response and renal injury. RNA-Sequencing (RNA-seq) can be used to study the whole transcriptome and detect splicing variants that are expressed in a specific cell type or tissue. We separate glomerulus from the renal biopsy tissues. After RNA extraction, the sequences were analyzed with Illumina HiSeq 2000/2500. 381 genes with differential expression between the IgAN patients and the healthy controls were identified. Only PLAU, JUN, and FOS were related to DNA damage, telomere dysfunction-induced aging markers, neutrophil function and IgA nephropathy. The networks showed the possibility of these genes being connected. We conclude that DNA damage and telomere dysfunction could play important roles in IgA nephropathy. In addition, neutrophils are also important factors in this disease. The networks of these markers showed the mechanism pathways that are involved in the duration of the occurrence and progression of IgA nephropathy and might be a new therapeutic opportunity for disease treatment.

Nocardiosis is a rare but life-threatening opportunistic infection, especially in immune compromised patients, including kidney transplant recipients. Primary pulmonary infection is the most common clinical pattern, and can easily result in disseminated Nocardia infection if treatment therapy is not adequate at the beginning. In this article, we report a new case of disseminated nocardiosis (lungs, skin, and pericardium) after renal allograft transplantation. We also review the English literature published from 1980 to 2010 and analyze the clinical characteristics of nocardiosis in kidney transplant recipients. © 2011 John Wiley & Sons A/S. Source

This study aimed to diagnose renal allograft dysfunction with specific biomarkers by serum proteomic analysis. Surface-enhanced laser desorption/ ionization time-of-flight mass spectrometry (SELDI-TOF MS) and bioinformatics (support vector machine and leave-one cross validation) were used to analyze serum proteome. Enrolled patients included 38 biopsy-proved acute rejection (BPAR), 10 acute tubular necrosis (ATN), 24 subclinical rejection (SCR) and 29 stable control recipients verified by protocol biopsy. A characteristic protein profile can be detected in each renal allograft dysfunction group. BPAR patients were differentiated from stable patients with markers of 9710.1, 4971, 6675.5, 8563.8, 6709.2, 9319 and 4476.7 Da with high sensitivity and specificity. ATN can be clearly distinguished from BPAR and stable control. Subclinical rejection differentiated from stable control with markers of 9193.1, 2759.1, 8464.6 Da. The independent blind test yielded with high specificity and sensitivity for each group. Serum proteome analysis by SELDI-TOF MS combined with bioinformatics in renal allograft dysfunction is valuable and promising. Specific markers were detected in each group. Identification of these proteins may prove useful as diagnostic markers for allograft dysfunction and better to elucidate the mechanism of acute rejection. © 2011 Springer Science+Business Media, B.V.

Purpose: To compare the long-term effects of the interleukin-2 receptor antagonist basiliximab versus rabbit antithymocyte globulin as an induction therapy for living-related renal transplantation. Methods: This is a prospective, open-label, nonrandomized, controlled study including 213 cases of renal transplant. Immunosuppressive therapy containing calcineurin inhibitors, mycophenolate mofetil and steroids was applied in all cases. The interleukin-2 receptor antagonist group (IL2Ra group) included 108 cases with 20 mg basiliximab induction on Day 0 and Day 4. The other 105 cases comprised the rabbit antithymocyte globulin group (rATG group) with 1.0 mg/kg/day ATG induction from Day 0 to Day 4. The primary endpoint was biopsy-proven acute rejection. Other endpoints included delayed graft function (DGF), graft loss and death. Results: All patients were followed up for 3 years. Acute rejection rates in the IL2Ra group and the ATG group were 5.6 and 3.8 % (P = 0.781), and the differences in the DGF rates, graft loss and death were insignificant between groups. All-cause infection rates in the IL2Ra and rATG groups were 26.9 and 43.8 % (P = 0.010). Urinary tract infections were more common in the rATG group than in the IL2Ra group (15.2 vs 6.5 %, P = 0.040). Specific viral infection rates were significantly different (18.1 % in rATG group vs 8.3 % in IL2Ra group, P = 0.035). Conclusions: IL2Ra and rATG had no significant differences as induction therapies during the perioperative period of living-related renal transplantation, according to acute rejection rates, DGF rates, graft loss, 1- and 3-year patient/graft survival rates. However, the incidence of infection, especially of urinary tract infection and specific viral infection, was higher in rATG-induced patients. © 2016, Springer Science+Business Media Dordrecht.
