This collection contains data collected in the course of clinical work in Nephrology across several hospitals In particular , the CMJAH Living Donor Clinic has a long history . You can see that the work of the unit has inspired or directly produced many thesis. We also have a selection of work on transplants. This collection also includes data on kidney disease from other tertiary hospitals in gauteng

PARTICIPANT NOTICE OF DATA SHARING FOR STUDY TITLED ‘EVALUATION OF POTENTIAL KIDNEY DONORS AND OUTCOMES POST-DONATION AT CHARLOTTE MAXEKE JOHANNESBURG ACADEMIC HOSPITAL (1983-2015)’.

Good day, The Division of Nephrology at Charlotte Maxeke Johannesburg Academic Hospital ( Previously JHB GEN)conducted a research study in the unit’s Living Donor Clinic. The study assessed clinical data of all individuals who presented to this clinic from January 1983 to July 2015. Written permission to access clinical records was obtained from the Human Research Ethics Committee (Medical) of the University of the Witwatersrand, Johannesburg. The purpose of the study was to analyze living kidney donation in the South African setting with the hope that the clinical findings of this research may contribute toward the future betterment of care for all potential kidney donors and that this data may expand upon the limited information available in this important field of study. As a patient belonging to this Living Donor Transplant Community, you have the right to direct how your information is shared for use by research platforms. You may engage with the principal investigator of this study should you have any queries regarding how the data from this study is being applied. You may also withdraw consent to share any information you feel is potentially identifying at any point. Should you require any further information regarding the study, please feel free to contact the principal investigator, Dr Chandni Dayal via email

or telephonically on 011 489 0467. Please note that prior to accessing your clinical records, approval was obtained from the Human Research Ethics Committee (Medical) of the University of the Witwatersrand, Johannesburg. A principal function of this Committee is to safeguard the rights and dignity of all individuals who are a part of research projects and the integrity of the research. If you have any complaints or concerns over the way the study was conducted, please contact the Chairperson of this Committee who is Dr. Clement Penny, on telephone number 011 717 2301, or by e-mail

    Establishment of a flow cytometric assay in the setting of renal transplant for T and B cell crossmatching
    (2014-02-17) Ramparsad, Narisha
    Donor specific crossmatching is performed prior to renal transplantation in order to determine the presence of pre-existing antibodies against donor HLA antigens which can result in hyperacute rejection. Flow cytometric crossmatching is reported in the literature to be a more sensitive and objective method of testing than the complement dependent cytotoxicity (CDC) method that is currently used in the Gauteng Province. A prospective analysis of the flow cytomeric crossmatch (FCXM) assay using the Luminex technology as the reference method was conducted. Forty-three samples were analysed. The T cell crossmatch (using a cutoff value of 2) revealed a sensitivity of 66.7%, a specificity of 83.8%, a positive predictive value (PPV) of 40% and negative predictive value (NPV) of 93.9%. The B cell crossmatch (using a cutoff value of 5) gave a sensitivity of 100%, specificity of 92.7%, and a PPV and NPV of 40 and100%, respectively. In addition, a retrospective analysis of clinical data for all patients transplanted during the period January 2008 to May 2009 was performed. Of a total of 50 patients assessed post transplant, none of the patients showed signs of hyperacute rejection, while twelve percent (12%) of patients revealed signs and symptoms suggestive of acute rejection. The validation of the flow cytometric crossmatch analysis was complex as there is no gold standard reference method. The assay was validated based on the clinical relevance of its high negative predictive value and the absence of hyperacute rejections in the clinical follow up. The rate of acute rejection found in this study is similar to that reported in literature.
If you, your family member or spouse was involved in the clinic , we urge you to read the notice above. You are welcome to comment on the data, express concerns or ask for changes in how the data is being shared. The library holds data in safekeeping for the researcher, for the community and for the sake of open science.
