The potential for successful regular PD programs in tropical countries has now been well established. Cost is a major prohibitive factor but the role of domestic manufacture in facilitating widespread use of PD is evidenced by the South African example. Education and training are direly needed and these are areas where international societies can be of great help.

PD IN DEvELOPING HEALTH CARE SYSTEmS♦ Introduction: After a training period, patients maintained on continuous ambulatory peritoneal dialysis (CAPD) assume responsibility for their own treatment. With the aid of appropriate tools, home visits help with ongoing evaluation and training for these patients. ♦ Methods: We conducted a home visit survey of 50 patients maintained on CAPD in Sudan between April 2009 and June 2010. Housing conditions, home environment, and patient's or caregiver's knowledge about peritoneal dialysis and the exchange procedure were evaluated using structured data collection sheets. Scores were compared with infection rates in the patients before the home visit. ♦ Results: Patients were maintained on CAPD for a median duration of 11 months. Their mean age was 42 ± 23 years; 70% were male; and 14% had diabetes. Only 34% of patients had suitable housing conditions, and 56% required assisted PD. Of the autonomous patients and assisting family members, 11.6% were illiterate. The median achieved knowledge score was 11.

Introduction: Despite an early start, the provision of renal replacement therapy (RRT) in Sudan is constrained by economic factors. This report describes the ESRD population and the available renal replacement therapy (RRT) services in Sudan in 2009. Current status: In June 2009, there were 2858 patients on hemodialysis (HD) in Sudan, 122 patients on continuous ambulatory peritoneal dialysis (CAPD), and 1168 kidney transplant recipients. The overall prevalence of treated ESRD was 106 patients per million population. All forms of RRT were funded by the government. The mean age of HD, CAPD and kidney transplant patients was 46±17, 42±22 and 39±13 years respectively. Males constituted 66%, 67.7% and 79.5% and children constituted 3.9%, 25.3% and 6.6% of HD, CAPD and kidney transplant patients respectively. The commonest reported cause of kidney failure was hypertension (26.1%), followed by diabetes mellitus (DM) (10.4%), obstructive uropathy (7.6%), glomerulonephritis (GN) (5.5%), polycystic kidney disease (2.6%), and pyelonephritis (1.1%). The majority of HD patients (83.8%) are offered twiceweekly HD, 83.6% had a functioning arterio-venous (AV) fistula, 6.4% were positive for hepatitis B virus (HBV) infection, 6.5% were positive for hepatitis C virus (HCV) infection, and 0.7% were positive for both HBV and HCV. Target blood pressure, hemoglobin and phosphorus levels were achieved by 26.5%, 23.1% and 28.5% of HD patients compared to 41.8%, 20.6% and 63.5% of CAPD patients respectively. Kidney transplant recipients had their transplant operation performed in Sudan (33.1%), Egypt (20.7%), KSA (18.2%), Jordan (14.8%), Pakistan (8.4%) and other countries. Conclusion: The prevalence of RRT in Sudan remains low. Hypertension and diabetes mellitus are the most commonly reported cause of kidney failure.

Introduction Review Conclusion Keywords

Introduction Gum Arabic (GA) is a complex polysaccharide with proven prebiotic properties and potentially beneficial systemic effects. Methods We randomly allocated 36 chronic kidney disease (CKD) patients to receive 10, 20, or 40 grams daily of GA for four weeks and studied the systemic effects of this intervention. Results Thirty participants completed the study with baseline glomerular filtration rate 29.1 ± 9.9 mL/min/1.7 m2. In contrast to previous observations, we found no effect on serum urea or creatinine levels. GA supplementation was associated with a small but statistically significant drop in serum sodium level (138 ± 2 to 136 ± 3 mmol/L, p = 0.002) without affecting other electrolytes, urine volume, or indoxyl sulfate (IS) levels. GA supplementation was also associated with a significant drop in C-reactive protein (CRP) level (3.5 ± 1.5 to 2.8 ± 1.6 ng/mL, p = 0.02) even in patients who received only 10 g/day (4.4 ± 1.2 to 3.2 ± 1.5 ng/mL, p = 0.03). Conclusions Supplementing the diet of CKD patients with 10–40 g/day of GA significantly reduced CRP level which could have a positive impact on these patients' morbidity and mortality. This trial is registered with Saudi Clinical Trial Registry number 15011402.
