T he prevalence of chronic kidney disease (CKD) and its risk factors is increasing worldwide, and there is a rapid rise in global need for the treatment of end-stage kidney disease (ESKD). The global nephrology community recognizes the need for a plan to address the growing incidence of CKD and a cohesive approach for CKD/ESKD integrated care. 1 This provides a major challenge for health systems, particularly
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.
♦ Background: Acute Kidney Injury (AKI) is an important cause of morbidity and mortality in developing countries. Although continuous renal replacement therapy is gaining more popularity worldwide, peritoneal dialysis (PD) in children remains an appropriate therapy for AKI in children for all age groups including neonates.
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.
BackgroundDengue fever, caused by dengue virus (DENV), has become one of the most important mosquito-borne viral diseases with a steady rise in global incidence, including the Sudan. Sporadic cases and frequent acute febrile illness outbreaks, compatible with Dengue fever, have been reported in El-Gadarif State, Sudan. However, diagnosis was based almost exclusively on clinical signs without confirmatory laboratory investigations. Despite the magnitude of the problem in El-Gadarif State, no information is currently available with regard to the epidemiology of the disease in this State. El-Gadarif State is one of the largest commercial centers in the Sudan. The objective of the present investigation is to estimate the prevalence of DENV antibodies, and determine the potential risk factors associated with seropositivity among residents of El-Gadarif State.MethodsA cross sectional study was conducted in a total of 701residents randomly selected from all 10 localities in El-Gadarif State. The sera from the 701 residents were tested for the presence of DENV-specific immunoglobulin G (IgG) antibodies using a commercially available Anti-dengue IgG enzyme-linked immunosorbent assay (ELISA).ResultsAmong the 701 residents, 334 residents (47.6%) were seropositive for DENV. Mosquito control (OR = 2.73, CI = 1.37–5.87, p-value = 0.001); low income (OR = 2.31, CI: 1.71–6.36, p value = 0.032); sleeping out-doors (OR = 3.73, CI = 2.63–6.23, p-value = 0.013), and localities were determined as potential risk factors for contracting DENV infection.ConclusionsThe prevalence rate of DENV antibodies among residents of El-Gadarif State is significantly high (47.6%). Further epidemiologic studies including, distribution of mosquito vectors and implementation of improved surveillance are urgently warranted for better prediction and prevention of a possible DENV outbreak in El-Gadarif State, Sudan.
SummaryPlasma 25-hydroxy cholecalciferol (25-OH vitamin D) concentrations were measured in 31 adult Saudi Arabian women who presented with acute minor illness. Patients with chronic diseases, malignancy and overt metabolic bone disease were excluded from this study. The median plasma 25-OH vitamin D concentration was 6 ng/ml (range: 2-18 ng/ml). Only three subjects had a concentration within the normal range (10-55 ng/ml). Plasma 25-OH vitamin D concentrations were significantly lower in subjects living in apartments than in those living in villas or rural areas (P<0-02). When direct questioning was used to assess exposure to sunlight, plasma 25-OH vitamin D concentrations were significantly lower in those subjects whose average exposure was less than 30 min daily than those whose exposure was more than 30 min daily (P=04002).Our findings confirm the importance of inadequate exposure to sunlight in the aetiology of vitamin D deficiency. Social customs may contribute to this deficiency in spite of abundant sunshine.Direct questioning to assess the adequacy of sunlight exposure is an essential part of history taking in cases of suspected vitamin D deficiency.KEY WORDS: plasma 25-hydroxy cholecalciferol, plasma alkaline phosphatase.
