Filter by:Purpose: This study aimed to determine the effect of motivational interviewing on self-management of treatment regimen, medication adherence, and patient outcomes in adult kidney transplant recipients between 3 months and 6 months after kidney transplant in the transplant outpatient clinic. Design: The research is a single-centered, single-blind, parallel and 1:1 randomized active comparative experimental study. Method: A total of 80 individuals, of the 40 in the control group and 40 in the intervention group, will be included in the study. Motivational interview sessions for the intervention group will be held 3 times between 15-30 minutes with an interval of 10 days. The control group will be given routine care (approximately 1 hour of face-to-face standard training) by the nurse educator. Within the research pattern, intervention and control groups will be applied pre-test at the first interview and post test after one month. In addition, follow-up test will be performed 3th month. The data will be obtained using the Self-Management Scale in Kidney Transplant Recipients, Visual Analog Scale (VAS) for self-care and VAS for medication adherence. In the study, Standard Protocol Items: Recommendations for Interventional Trials- SPIRIT(2013) and CONSORT 2010 (Consolidated Standards of Reporting Trials) were used.
Older patients with end- stage kidney disease (ESKD) are at very high risk for functional impairment. Kidney transplantation (KT) has the potential to ameliorate the detrimental effects of ESKD on physical activity and functional status. However, KT alone may not meet the full extent of this potential, particularly for older or more impaired adults. In fact, activity declines immediately post-KT and fails to return to expected levels even 5 years post-KT. Older patients waitlisted for KT (most of whom are on dialysis) are therefore reliant on their pre-KT levels of exercise, which are also predictive of post-KT mortality. "Prehabilitation" has been used in other surgical populations to minimize functional loss, and a structured exercise program may be beneficial in the pre- KT setting. However, few waitlisted patients are able to participate in typical exercise interventions due to barriers such as severe fatigue. Older patients have additional barriers such as further mobility impairment and requiring substantial caregiver support. Therefore for older living donor kidney transplant candidates, it is necessary to address issues such as specifics of coaching, timing, and importantly, incorporate caregiver participation. The overall objective of this proposal is to adapt a previously developed 8- week, home- based, structured exercise program among older (≥50 years) dialysis patients awaiting living donor KT, with a focus on caregiver involvement. The investigators will trial the exercise program as compared to usual care. The investigators will then pilot the refined intervention in a total of 72 patient-caregiver dyads, 48 of whom will undergo the proposed intervention (24 with caregiver participation, 24 without). The primary outcomes for the pilot will be change in physical performance and activity from baseline to after the intervention, along with measurements of exploratory quality of life outcomes. In addition, the investigators will measure these same outcomes at 3- months post KT to evaluate for a durable effect of the intervention. An additional post-transplantation outcome of interest will be number of days hospitalized within 3 months of transplantation.
CMV infection in transplantation remains the most frequent infectious complication causing increased morbidity and mortality. International recommendations advocate prevention of this infection by instituting direct antiviral treatment or monitoring viral replication by PCR with the start of curative antiviral treatment when the DNAemia is positive. The risk of CMV infection varies according to the serostatus of the donor (D) and recipient (R) at the time of transplantation. In the absence of prophylaxis, CMV infection occurs in 60-80% of D+R-, 50-60% of D+R+ and 25-50% of D-R+. The humoral anti-CMV response is represented by the production of antibodies to envelope proteins (gB and gH) and to molecules involved in viral attachment and entry into target cells. However, the majority of CMV-specific antibodies do not have antiviral neutralising activity. The investigators have identified a new player in the specific anti-CMV response expressing the Fc RIIIa receptor (CD16), that interacts with anti-CMV immunoglobulins (Ig): the Tgamma-delta V delta 2-negative lymphocyte (LTgdVd2neg). This lymphocyte subpopulation shows persistent expansion in the peripheral blood of kidney transplant patients with CMV infection. These cells express an effector-memory phenotype (CD45RA+/CD27-). This expansion is associated with resolution of infection in patients. The investigators have shown that CD16 is specifically and constitutively expressed on the surface of CMV-induced LTgdVd2neg in healthy volunteers and kidney transplant patients. The investigators have observed that one of the antiviral activities of anti-CMV IgG lies in its binding to the Fc RIIIa receptor (CD16) on the surface of LTgdVd2neg. The anti-CMV IgGs capturing virions thus activate CD16+ LTgdVd2neg with production of IFN interferon which in turn is responsible for inhibition of CMV viral multiplication. Anti-CMV IgG is a recommended therapeutic option, with a marketing authorisation for the prevention of CMV infection in kidney transplantation in Europe and a Temporary Authorisation for Use in France. Thus, R+ patients expressing a significant level of LTgdVd2neg CD16+ at D0 of transplantation could be protected against CMV, in the absence of direct antiviral treatment by the addition of anti-CMV Ig.
Observational study of patients with End Stage Kidney Disease on dialysis and Kidney Transplant Recipients, before and after vaccination for SARS-COV 2, after written consent, with the aim of laboratory efficacy of the vaccine and safety regarding the clinical outcome of patients and possible complications.
The purpose of this study is to investigate the effect of empagliflozin on oxidative stress in patients with type 2 diabetes after kidney transplantation. The association is examined by comparing the difference in oxidative modifications before and after 90 days treatment with 25 mg empagliflozin plus insulin compared to insulin treatment. The study is randomised and double-blinded. Each treatment group consists of 20 patients. Oxidative stress markers are measured by serum level of superoxide dismutase activity ,lipid peroxidation assay kit, glutathione assay, glutathione peroxidase activity , total antioxidant capacity assay oxidant status , carbonyl content assay and bca protein assay . . A student t-test will be performed to compare adding empagliflozin . The results will be published in a peer-review journal.
Living donor (LD) kidney transplantation is the optimal treatment for patients with end-stage kidney disease (ESKD). However, LDs take on a higher risk of future ESKD themselves. African American (AA) LDs have an even greater, 3.3-fold, risk of ESKD than white LDs post-donation. Because evidence suggests that Apolipoprotein L1 (APOL1) risk variants contribute to this greater risk, transplant nephrologists are increasingly using APOL1 testing to evaluate LD candidates of African ancestry. However, nephrologists do not consistently perform genetic counseling with LD candidates about APOL1 due to a lack of knowledge and skill in counseling about APOL1. Without proper counseling, APOL1 testing will magnify LD candidates' decisional conflict about donating, jeopardizing their informed consent. Given their elevated risk of ESRD post-donation, and AAs' widely-held cultural concerns about genetic testing, it is ethically critical to protect AA LD candidates' safety through APOL1 testing in a culturally competent manner to improve informed decisions about donating. No transplant programs have integrated APOL1 testing into LD evaluation in a culturally competent manner. Clinical "chatbots," mobile apps that use artificial intelligence to provide genetic information to patients and relieve constraints on clinicians' time, can improve informed treatment decisions and reduce decisional conflict. The chatbot "Gia," created by a medical genetics company, can be adapted to any condition. However, no chatbot on APOL1 is currently available. No counseling training programs are available for nephrologists to counsel AA LDs about APOL1 and donation in a culturally competent manner. Given the shortage of genetic counselors, increasing nephrologists' genetic literacy is critical to integrating genetic testing into practice. The objective of this study is to culturally adapt and evaluate the effectiveness of an APOL1 testing program for AA LDs at two transplant centers serving large AA LD populations (Chicago, IL, and Washington, DC). The APOL1 testing program will evaluate the effect of the culturally competent testing, chatbot, and counseling on AA LD candidates' decisional conflict about donating, preparedness for decision-making, willingness to donate, and satisfaction with informed consent. The specific aims are to: 1. Adapt Gia and transplant counseling to APOL1 for use in routine clinical practice 2. Evaluate the effectiveness of this intervention on decisional conflict, preparedness, and willingness to donate in a pre-post design 3. Evaluate the implementation of this intervention into clinical practice by using the RE-AIM framework to longitudinally evaluate nephrologist counseling practices and LDs' satisfaction with informed consent. The impact of this study will be the creation of a model for APOL1 testing of AA LDs, which can then be implemented nationally via implementation science approaches. APOL1 will serve as a model for integrating culturally competent genetic testing into transplant and other practices to improve patient informed consent.
CREST-KT is a single-center, double-blinded, randomized trial of empagliflozin therapy in 72 kidney transplant recipients with (n=36) and without type 2 diabetes (n=36). After evenly dividing patients by type 2 diabetes diagnosis, patients will be randomized 2:1 to empagliflozin 10mg versus placebo.
Microvascular inflammation, the hallmark histological criteria of antibody-mediated rejection in kidney transplantation, remains an issue in routine practice, due to a lack of reproducibility in its recognition by pathologists and an incomplete comprehension of its pathophysiology, leading to a poor treatment efficacy. The main objective of this study is to assess the performances of tissue proteic signatures designed for the diagnosis of microvascular inflammation in kidney transplantation, from formalin-fixed and paraffin-embedded (FFPE) allograft biopsies analyzed by mass spectrometry-based proteomics.
This study is designed to determine the safety and efficacy of two calcineurin inhibitor free treatment groups 1) a belatacept, everolimus and early corticosteroid withdrawal (ECSWD) immunosuppressive regimen with rabbit antithymocyte globulin induction (rATG) and 2) a belatacept, mycophenolate, chronic steroid regimen with rATG and compare to historical controls of tacrolimus-based and belatacept-based regimens in combination with rATG induction, mycophenolate, and ESWD in renal transplant recipients. The purpose is to evaluate the effect of 2 regimens (rATG induction/belatacept/everolimus/ESWD and rATG induction/belatacept/mycophenolate/CS) on the composite of patient death, graft loss, or eGFR (MDRD) < 45 mL/min/1.73m2 at Month 12 post-transplantation compared to historical controls of the BEST Trial (groups B and C).
The aim of the study is to investigate pulmonary hemodynamics at rest and during exercise in patients before and after kidney transplantation.
