RESUMEN
Renal transplantation is not readily available in the majority of countries in Africa. It is expensive and difficult to sustain on the meagre funds allocated to health. We report our short experience with fifteen living donor recipients followed in our unit for at least 24 months, range 26 - 48 (mean 35 months) post-transplantation. The donors and recipients were mostly young adults with mean ages of 36.7 years and 32.6 years respectively. The majority of the donors and recipients were males. The donors in most cases were siblings. Within this time, one graft has been lost at one year and the patient restarted on haemodialysis. Three patients died, two within the first year, the third at 23 months after transplantation, all with functioning grafts. The one year graft and patient survival rates were 93% and 86.6% respectively. The second year graft survival rates remained at 93% and the patients survival rate 80%. The nature and frequency of complications seen in these patients is comparable to those in other centres. Of all medical complications, bacterial infections contributed 69.4% of all infections. Cardiovascular complications comprised 31.25% of the complications. Hypertension seen in 85.5% of the patients accounted for 65% of the cardiovascular complications. Acute rejections were common and occurred in seven patients. Transplantation is a viable mode of renal replacement therapy (RRT) in our environment. The practice should be supported to make it more readily available to the many young end stage renal failure (ESRF) patients.

Phosphate binders are necessary to control hyperphosphataemia in the majority of dialysis patients. Whilst aluminium salts are efficient phosphate binders, their use is associated with toxic side effects. Calcium salts are a widely used alternative, but hypercalcaemia is a common side effect, limiting their use and raising concern about metastatic calcification. Reduction of the dialysis fluid calcium concentration has been shown to reduce hypercalcaemia in haemodialysis patients, with an associated decrease in serum PTH. We analysed the effect of reduced calcium/magnesium (1.25/0.25 mmol/l), 40 mmol/l lactate, PD fluid (PD4) on 11 CAPD patients with uncontrollable hypercalcaemia (> 2.65 mmol/l) and hyperphosphataemia (> 1.80 mmol/l). Only 1 patient remained hypercalcaemic, while phosphate fell in 6 patients (2.23 +/- 0.16 on no binder, to 1.68 +/- 0.08 mmol/l at 6 months (p < 0.05), but was unchanged in 5 (2.10 +/- 0.15 to 2.48 +/- 0.14 mmol/l [p = NS]). Overall mean calcium x phosphate product changed little. However, in a subgroup it fell significantly (p < 0.05). Geometric mean iPTH rose, but not significantly. The subgroup of patients whose calcium x phosphate product fell, exhibited a much smaller rise in iPTH than the others (57.3-73.2 vs. 52.8-167.1 pg/ml). 1.25-Dihydroxyvitamin D3 was subnormal in all patients. Mean serum magnesium fell from 1.24 +/- 0.06 to 0.89 +/- 0.04 mmol/l (p < 0.001), whilst mean serum bicarbonate rose significantly (25.2 +/- 0.4 to 28.9 +/- 1.2 mmol/l; p < 0.01). Withdrawal of aluminium-containing phosphate binders resulted in mean serum aluminium falling significantly from 31.1 +/- 5.7 at start of PD4 to 15.4 +/- 2.7 mu g/l at 6 months (p < 0.05). In summary, in around 50% of CAPD patients with persistent hypercalcaemia and hyperphosphataemia, reduction in PD fluid calcium can produce significant improvement in phosphate, reduction of calcium x phosphate product, and enable avoidance of aluminium-containing phosphate binders. Patients whose calcium and phosphate control remains poor, still benefit from the reduction, or cessation, of oral aluminium intake.

End stage renal disease requiring renal replacement therapy is a common complication of several renal diseases that are seen in the tropics. World over, the costs of the various modalities of therapy that constitute renal replacement therapy, including hemodialysis, continuous ambulatory peritoneal dialysis and renal transplantation, is prohibitive. All the above modes of therapy are provided in Kenya, unlike most countries with similar level of socioeconomic development. This article analyses the factors behind the limited success that renal replacement therapy enjoys in Kenya, which is faced with more pressing basic problems of malnutrition and infection.

Oral infection with Herpes Simplex Virus (HSV) is a frequent and well documented complication in immunosuppressed individuals including patients on immunosuppressive medication. We report the development of severe oral infection with HSV type 1 in a 34 year old woman with type 1 diabetes mellitus and end stage renal disease (ESRD) following cadaveric renal transplantation at the Western General Hospital, Edinburgh. The role of acyclovir in therapy and chemoprophylaxis is discussed.

This study was undertaken to evaluate: 1. The efficacy of netilmycin and vancomycin as combined first line antimicrobial regime, compared to cefuroxime, in the treatment of peritonitis. 2. To measure the levels of netilmycin and vancomycin in the serum and dialysate. 3. To report on the use of this combination over a one year period and compare it with that of cefuroxime used during the previous one year.

Forty seven patients with acute renal failure were studied prospectively over a two-year period at the Kenyatta National Hospital. There were 20 males and 27 females. The mortality rate was 40.4%. Most patients had medically oriented problems. Complications that were associated with a high mortality were infections and the presence of neuropsychiatric manifestations.
