Circulating Levels of Adhesion Molecules in Chronic Kidney Disease Correlate with the Stage of Renal Disease and with C-Reactive Protein
2007
Patients with chronic renal failure (CRF) suffer from a series of complications linked to the atherosclerotic process in which the endothelial dysfunction mediated by the activation of some adhesion molecules plays an important role. This study aims to evaluate circulating levels of intercellular adhesion molecules-1 (ICAM-1) and vascular cell adhesion molecules-1 (VCAM-1) in patients with predialysis CRF, on maintenance hemodialysis (HD) and after kidney transplantation (KTx) and to correlate them with some inflammation and nutritional indexes.Thirty two patients with predialysis CRF, 30 on maintenance HD, 36 after KTx and 28 subjects as a control group (C) were included in this study. Cir…
Lipoprotein a) levels in end-stage renal failure and renal transplantation
1993
Some previous studies have documented an increase in lipoprotein (a) [Lp(a)] levels in renal diseases. Here, we report data in subjects with end-stage renal failure treated with hemodialysis (HD) or with continuous ambulatory peritoneal dialysis (CAPD) and in renal transplant recipients (RTR), compared with a group of normolipidemic controls (C). Lp(a) levels were significantly increased in HD and CAPD patients in comparison with C, while they were only slightly increased in RTR. Both HD and CAPD patients showed Lp(a) levels higher than in RTR, but no difference was found between the subjects of the two dialysis procedures. The prevalence of Lp(a) levels > 25 mg/dl was significantly higher …
Dialysis and Kidney Transplantation: Similarities and Differences in the Psychological Aspects of Noncompliance
2006
Abstract Background Dialysis and kidney transplantation represent two effective strategies in treating chronic uremia, albeit with different results. Our study compared the psychological aspects of two categories of patients: patients who faced kidney transplantation and have been on dialysis, and noncompliant patients treated with these therapies. Materials and Methods On 170 patients (120 hemodialysis and 50 peritoneal dialysis) we used a personality analysis (MMPI2) and the COPE, which assessed the ability of patients to cope under certain conditions that can be perceived as stressful or, in any case, unusual. The screening succeeded in 11 cases among the first group and 9 in the second.…
Mesh or no mesh: a hamletic dilemma to prevent Renal Allograft Compartment Syndrome (RACS)
2014
Tension-free muscle closure is essential in kidney transplantation, both in adult and pediatric patients. Tight muscle closure may lead to renal allograft compartment syndrome either due to compression of the renal parenchyma or due to kinking of the renal vessels. It may also cause kinking of the transplant kidney ureter, wound dehiscence and incisional hernia. Many techniques have been proposed in an attempt to achieve tension-free closure. There is a wrong belief among surgeons that using prosthetic mesh may increase the incidence of infective complications in these immunosuppressed patients. Also, there is fear that one is not able to monitor the renal graft by ultrasound and perform bi…
Double Endocrine Neoplasia in a Renal Transplant Recipient: Case Report and Review of the Literature
2011
Abstract Introduction The incidence of cancer compared for age groups is 3–4 times higher in transplant recipients than the general population. The increased risk is related to immunosuppressive therapy as well as the use of increasingly older donors and recipients. Although cardiovascular disease with a functioning transplant is the leading cause of death (47%), cancer mortality is significant especially among older patients. However, the most frequent posttransplantation cancers relate to hemolymphopoietic organs and skin, whereas the occurrence of solid tumors elsewhere is rare. Herein we have described a rare case of synchronous double malignancy of endocrine organs (thyroid-adrenal) in…
Improved short-term outcomes of kidney transplants in controlled donation after the circulatory determination of death with the use of normothermic r…
2021
Normothermic Regional Perfusion (NRP) allows the in situ perfusion of organs with oxygenated blood in donation after the circulatory determination of death (DCDD). We aimed at evaluating the impact of NRP on the short-term outcomes of kidney transplants in controlled DCDD (cDCDD). This is a multicenter, nationwide, retrospective study comparing cDCDD kidneys obtained with NRP versus the standard rapid recovery (RR) technique. During 2012-2018, 2,302 cDCDD adult kidney transplants were performed in Spain using NRP (n=865) or RR (n=1,437). The study groups differed in donor and recipient age, warm and cold ischemic time and use of ex situ machine perfusion. Transplants in the NRP group were m…
Baclofenintoxikation bei chronischer Hämodialyse und Nierentransplantation
2008
Fourteen days after renal transplantation, at first gave with good transplant function, a 36-year-old woman developed neurogenic dysfunction of bladder emptying. This was treated with baclofen, 5 mg three times daily by mouth. Between the 7th and 10th treatment day she progressively developed an organic psychotic syndrome and increasing respiratory paralysis after the onset of renal failure, associated with rejection of the transplanted kidney which required dialysis. Plasma concentration of baclofen was 565 ng/ml (therapeutic range 80-400 ng/ml). After discontinuing the drug and renewed haemodialysis the baclofen level rapidly fell and the symptoms receded. In a second case, a 57-year-old …
CD4 monoclonal antibody VIT4 in human alloimmune response in vitro and in vivo.
1996
In the present report the immunosuppressive effects of the murine anti-human CD4 monoclonal antibody (mAb) VIT4 on human alloimmune response in vitro were analyzed. Moreover, the antibody was tested for its activity to prolong allograft survival in seven patients with steroid-refractory allograft rejection. VIT4 inhibited the proliferative response to alloantigens in the mixed lymphocyte reaction (MLR) in a dose-dependent manner. At concentrations of 1 and 10 micrograms/ml VIT4 blocked MLR by 55 +/- 11% and 77 +/- 1%, respectively. Also alloantigen-specific proliferation of in vitro- generated memory T cells was dose-dependently reduced to 23 +/- 1% at a VIT4 concentration of 100 micrograms…
Primary Cytomegalovirus Infection in Seronegative Kidney Transplant Patients Is Associated with Protracted Cold Ischemic Time of Seropositive Donor O…
2017
Human Cytomegalovirus (CMV) can lead to primary infection or reactivation in CMV-seronegative or -seropositive kidney transplant recipients, respectively. Complications comprise severe end-organ diseases and acute or chronic transplant rejection. Risk for CMV manifestation is stratified according to the CMV-IgG-serostatus, with donor+/recipient- (D+/R-) patients carrying the highest risk for CMV-replication. However, risk factors predisposing for primary infection in CMV-seronegative recipients are still not fully elucidated. Therefore, we monitored D+/R- high-risk patients undergoing kidney transplantation in combination with antiviral prophylaxis for the incidence of CMV-viremia for a med…
Anti-HLA immunization of patients qualified for lung transplantation – Single center study
2021
For lung transplantation, the presence of donor-specific anti-HLA antibodies (DSA) is an important factor of antibody-mediated rejection (AMR) in its hyperacute, acute or chronic form during long-term follow up. The aim of the study was to assess the allosensitization of Polish patients qualified for a lung transplantation in our center. A retrospective study of 161 potential lung allograft recipients, also of 31 patients transplanted in the Uni-versity Hospital of Gdansk, between June 2018 and December 2020 were performed. 121 potential recipients were thoroughly tested for immunization status before eventual lung transplantation. SAB-testing, PRA-CDC and vPRA assessment, and HLA typing we…
