Capacity for the management of kidney failure in the International Society of Nephrology Africa region: report from the 2023 ISN Global Kidney Atlas (ISN-GKHA).

The burden of chronic kidney disease and associated risk of kidney failure are increasing in Africa. The management of people with chronic kidney disease is fraught with numerous challenges because of limitations in health systems and infrastructures for care delivery. From the third iteration of the International Society of Nephrology Global Kidney Health Atlas, we describe the status of kidney care in the ISN Africa region using the World Health Organization building blocks for health systems. We identified limited government health spending, which in turn led to increased out-of-pocket costs for people with kidney disease at the point of service delivery. The health care workforce across Africa was suboptimal and further challenged by the exodus of trained health care workers out of the continent. Medical products, technologies, and services for the management of people with nondialysis chronic kidney disease and for kidney replacement therapy were scarce due to limitations in health infrastructure, which was inequitably distributed. There were few kidney registries and advocacy groups championing kidney disease management in Africa compared with the rest of the world. Strategies for ensuring improved kidney care in Africa include focusing on chronic kidney disease prevention and early detection, improving the effectiveness of the available health care workforce (e.g., multidisciplinary teams, task substitution, and telemedicine), augmenting kidney care financing, providing quality, up-to-date health information data, and improving the accessibility, affordability, and delivery of quality treatment (kidney replacement therapy or conservative kidney management) for all people living with kidney failure.

Public-private partnership in hemodialysis in Nigeria: A comparative analysis of renal centers across three Northwestern states.

Background: Public-private partnership (PPP) in hemodialysis delivery in Nigeria is a new concept. We set out to compare the performance of Specialist Hospital Sokoto's (SHS) renal center operating with this model with four other neighboring government-operated dialysis centers. Materials and Methods: We reviewed the 6-year records (May 2011 to April 2017) of Dialysis Center of SHS, operated under a PPP and compared some performance indicators with four government-operated dialysis centers over the same period. Comparisons were made using Chi-square and corresponding P values were reported accordingly. P < 0.05 was considered significant. Results: A total of 1167 patients' data were studied. Of these, 252 (21.6%) patients with end-stage renal disease were dialyzed at SHS. The SHS dialysis center experienced 5 months of interruption in dialysis service. Only 38 (15.1%) patients sustained dialysis beyond 90 days and 105 (41.7%) patients had more than three sessions of hemodialysis. Only one patient was referred for kidney transplant from the dialysis center during the review period. SHS performed better than Federal Medical Center and Sir Yahaya Hospitals in terms of service availability, duration on hemodialysis, and greater number of hemodialysis sessions (χ2 = 29.06, df = 3, P < 0.001). Conclusion: PPP has improved the availability of dialysis service, mean duration on dialysis, and mean number of dialysis sessions but did not improve the kidney transplant referral rate at SHS. There is a need to encourage the current arrangement in the Hospital as well as other centers offering similar partnerships.

RésuméContexte: Le partenariat public-privé (PPP) dans la prestation d'hémodialyse au Nigéria est un nouveau concept. Nous avons entrepris de comparer les performances du centre rénal de l'hôpital spécialisé de Sokoto fonctionnant avec ce modèle avec quatre autres centres de dialyse gérés par le gouvernement voisin. Méthodes: Nous avons examiné les dossiers de six ans (mai 2011 à avril 2017) du centre de dialyse de l'hôpital spécialisé de Sokoto, exploité dans le cadre d'un partenariat public-privé et comparé certains indicateurs de performance avec quatre centres de dialyse gérés par le gouvernement au cours de la même période. Des comparaisons ont été faites en utilisant le chi carré et les valeurs p correspondantes ont été rapportées en conséquence. Une valeur p <0.05 était considérée comme significative. Résultats: Un total de 1167 données de patients a été étudié. Parmi ceux-ci, 252 (21.6%) patients atteints d'insuffisance rénale terminale ont été dialysés à l'hôpital spécialisé de Sokoto (SHS). Le centre de dialyse SHS a connu cinq mois d'interruption de service de dialyse. Seuls 38 (15.1%) patients ont subi une dialyse au-delà de 90 jours et 105 (41.7%) patients ont eu plus de trois séances d'hémodialyse. Un seul patient a été référé pour une transplantation rénale depuis le centre de dialyse pendant la période d'examen. L'hôpital spécialisé de Sokoto a obtenu de meilleurs résultats que le centre médical fédéral et les hôpitaux Sir Yahaya en termes de disponibilité des services, de durée d'hémodialyse et de plus grand nombre de séances d'hémodialyse (χ2 = 29.06, df = 3, p <0.001). Conclusion: PPP a amélioré la disponibilité du service de dialyse, la durée moyenne de la dialyse, le nombre moyen de séances de dialyse mais n'a pas amélioré le taux de référence pour une greffe de rein à l'hôpital spécialisé de Sokoto. Il est nécessaire d'encourager l'arrangement actuel à l'hôpital ainsi que dans d'autres centres offrant des partenariats similaires.

Kidney care in low- and middle-income countries.

Optimal kidney care requires a trained nephrology workforce, essential healthcare services, and medications. This study aimed to identify the access to these resources on a global scale using data from the multinational survey conducted by the International Society of Nephrology (ISN) (Global Kidney Health Atlas (GKHA) project), with emphasis on developing nations. For data analysis, the 125 participating countries were sorted into the 4 World Bank income groups: low income (LIC), lower-middle income (LMIC), upper-middle income (UMIC), and high income (HIC). A severe shortage of nephrologists was observed in LIC and LMIC with < 5 nephrologists per million population. Many LIC were unable to access estimated glomerular filtration rate (eGFR) and albuminuria (proteinuria) tests in primary-care levels. Acute and chronic hemodialysis was available in most countries, although acute and chronic peritoneal dialysis access was severely limited in LIC (24% and 35%, respectively). Most countries had kidney transplantation access, except for LIC (12%). HIC and UMIC funded their renal replacement therapy (RRT) and renal medications primarily through public means, whereas LMIC and LIC required private and out-of-pocket contributions. In conclusion, this study found a huge gap in the availability and access to trained nephrology workforce, tools for diagnosis and management of CKD, RRT, and funding of RRT and essential medications in LIC and LMIC.

Prevalence and outcome of hypoglycemia in children attending emergency pediatric unit of a specialist hospital in Nigeria

Background: Hypoglycemia is a common metabolic problem encountered in pediatric emergency admissions. The absence of clinical symptoms does not preclude the presence of hypoglycemia as presentation may vary from asymptomatic to central nervous system and cardiopulmonary disturbances. If untreated, hypoglycemia can result in permanent neurological damage or even death. Objectives: The objective of the study is to determine the prevalence, associated factors and outcome of hypoglycemia in pediatric emergency admissions at Ahmad Sani Yariman Bakura Specialist Hospital, Gusau, Nigeria. Materials and Methods: The study was a prospective cross­sectional study involving children aged 1 month­13 years. Blood glucose was determined at admission using Accu­Chek® Active Blood Glucose Meter, and hypoglycemia was defined as blood glucose levels <2.8 mmol/L (<50 mg/dL). Age of the patients, sex, interval of last meal, presenting complaints diagnoses were recorded. Results: A total of 154 children were studied.Thirty (19.5%) were infants and 71 (46.1%) were under­fives. Eighty­seven (56.5%) were males with male to female ratio of 1.3:1.The prevalence of hypoglycemia was 22.1%. The predominant disease conditions the children with hypoglycemia presented with were severe malaria, acute diarrheal disease, and sepsis. The prevalence of hypoglycemia was significantly higher among children whose last meal was 8 h and above before presentation (42.9%). Children who presented with hypoglycemia were significantly more likely to die (odds ratio [OR] =13.3; 95% confidence interval [CI] =4.6­38.7). Among those with hypoglycemia, males were significantly more likely to die (OR = 4.2, 95% CI = 1.0­18.0). Hypoglycemia was significantly associated with mortality in children with severe malaria and pneumonia (P = 0.04 and 0.01, respectively). Conclusion: The prevalence of hypoglycemia is still high in our emergency admissions. It is associated with significant mortality especially among male children and those presenting with severe malaria and pneumonia. We recommend that hypoglycemia sought for and promptly treated in children presenting to emergency to reduce mortality

Global overview of health systems oversight and financing for kidney care.

Reliable governance and health financing are critical to the abilities of health systems in different countries to sustainably meet the health needs of their peoples, including those with kidney disease. A comprehensive understanding of existing systems and infrastructure is therefore necessary to globally identify gaps in kidney care and prioritize areas for improvement. This multinational, cross-sectional survey, conducted by the ISN as part of the Global Kidney Health Atlas, examined the oversight, financing, and perceived quality of infrastructure for kidney care across the world. Overall, 125 countries, comprising 93% of the world's population, responded to the entire survey, with 122 countries responding to questions pertaining to this domain. National oversight of kidney care was most common in high-income countries while individual hospital oversight was most common in low-income countries. Parts of Africa and the Middle East appeared to have no organized oversight system. The proportion of countries in which health care system coverage for people with kidney disease was publicly funded and free varied for AKI (56%), nondialysis chronic kidney disease (40%), dialysis (63%), and kidney transplantation (57%), but was much less common in lower income countries, particularly Africa and Southeast Asia, which relied more heavily on private funding with out-of-pocket expenses for patients. Early detection and management of kidney disease were least likely to be covered by funding models. The perceived quality of health infrastructure supporting AKI and chronic kidney disease care was rated poor to extremely poor in none of the high-income countries but was rated poor to extremely poor in over 40% of low-income countries, particularly Africa. This study demonstrated significant gaps in oversight, funding, and infrastructure supporting health services caring for patients with kidney disease, especially in low- and middle-income countries.

Proteinuria, graft outcomes, and cardiovascular risk among kidney transplant recipients in a South African Public Hospital.

Proteinuria is a marker of poor long-term graft survival and an independent risk factor for total and cardiovascular mortality in the transplant population. We investigated the prevalence of proteinuria and its relationship with graft function and cardiovascular risk factors in kidney transplant recipients (KTRs). Adult KTRs at the Charlotte Maxeke Johannesburg Academic Hospital were recruited. Patients' records were reviewed for information on their posttransplant follow-up. Echocardiography and carotid Doppler were performed for the assessment of cardiac status and carotid intima-media thickness (CIMT), respectively. Proteinuria was analyzed both as a categorical and continuous variable. Graft dysfunction was defined as estimated glomerular filtration rate of <60 mL/min/1.73 m 2 based on the modification of diet in renal disease formula. Framingham's risk score was used to categorize patients' cardiovascular risk. Inferential and modeling statistics were applied as appropriate using Statistical Package for Social Sciences, and P ≤0.05 was considered statistically significant. One hundred KTRs including 63% males were recruited. Proteinuria was present in 51%, the mean ± standard deviation 24 h urinary protein excretion per day was 1.67 ± 2.0 g/day with a range of 0.4-9.4 g/day. Graft dysfunction was found in 52% of patients and 36% had high cardiovascular disease (CVD) risk. Proteinuric KTRs had high CVD risk, P = 0.002. Proteinuria was associated with graft dysfunction, increased left ventricular mass index, increased CIMT, and anemia. Proteinuria is prevalent; it is a marker of graft dysfunction and is associated with markers of atherosclerosis.
