    Metabolic syndrome, the leptin gene and kidney disease in non-diabetic black South Africans
    (2008) Okpechi, Ikechi Gareth; Meissner, P; Rayner, B L; Ramesar, R; Pascoe, M D
    Obesity is a worldwide problem and is a factor in the pathogenesis of the metabolic syndrome and kidney disease through the development of obesity-related hypertension and neurohormonal mechanisms that include the action of leptin. As there appear to be no focussed studies that have looked at the association of the LEP gene with kidney disease phenotypes or cardiovascular disease markers like hypertension, the metabolic syndrome and obesity, and especially so in native black Africans, this study sought to establish an association between the obesity gene (LEP) and kidney disease phenotypes (independent of diabetes and hypertension) in a homogenous black African population.

    Overview of a paediatric renal transplant programme
    (2006) McCulloch, M; Gajjar, P; Spearman, W; Burger, H; Sinclair, P; Savage, L; Morrison, C; Davies, C; Ruysch van Dugteren, GPA; Maytham, D; Wiggelinkhuizen, J; Pascoe, M D; McCurdie, F J; Pontin, A; Muller, E; Numanoglu, A; Millar, A J W; Rode, H; Khan, D
    INTRODUCTION: Renal transplantation is the therapy of choice for children with end-stage renal failure. There are many challenges associated with a paediatric programme in a developing country where organs are limited. METHODS: A retrospective review was undertaken of 149 paediatric renal transplants performed between 1968 and 2006 with specific emphasis on transplants performed in the last 10 years. Survival of patients and grafts was analysed and specific problems related to drugs and infections were reviewed. RESULTS: On review of the total programme, 60% of the transplants have been performed in the last 10 years, with satisfactory overall patient and graft survival for the first 8 years post transplant. At this point, transfer to adult units with non-compliance becomes a significant problem. Rejection is less of a problem than previously but infection is now a bigger issue--specifically tuberculosis (TB), cytomegalovirus (CMV) and Epstein-Barr virus (EBV) infections with related complications. A wide variety of drugs are available for tailoring immunosuppression to minimise side-effects. CONCLUSION: It is possible to have a successful paediatric transplant programme in a developing country. However, to improve long-term outcomes certain issues need to be addressed, including reduction of nephrotoxic drugs and cardiovascular risk factors and providing successful adolescent to adult unit transition.

    Technology in nephrology
    (Health and Medical Publishing Group, 2003) Pascoe, M D; Halkett, J
    Early nephrological referral allows for uncomplicated transition to dialysis and improves long-term survival. Peripheral veins require careful preservation for future vascular access in patients with renal disease. Improved biocompatibility of modern polysulphone and other membranes reduces the inflammatory response to dialysis. The increased permeability of these modern membranes improves the clearance of solutes but does require volumetrically controlled machines. Volumetric dialysis equipment allows the patient’s fluid balance to be very precisely controlled. Continuous dialysis therapies for acute renal failure allow for dialysis for acutely ill patients who would not tolerate standard intermittent haemodialysis. Continuous dialysis for acute renal failure allows for intensive nutritional support and improved and more stable metabolic and volume control than standard dialysis. Continuous dialysis is the treatment of choice for patients with raised intracranial pressure. Bicarbonate-buffered dialysis fluid provides better acid-base control than standard acetate dialysis. Advances in technology are expensive and cost control is of increasing importance.
