Guidelines for the prevention, detection and management of the renal complications of COVID-19 in Africa

Africa trails the rest of the world in COVID-19 cases and deaths. However, as the pandemic spreads through the continent, we expect increases in community infection in the months ahead. Patients with kidney infection, especially those with end-stage kidney disease and those with kidney transplants, are at high risk for acquiring the disease and dying from it. While there is limited evidence for the benefit of interventions, we have the advantage of learning from the experiences of those in China, Europe and the Americas. This document sets forth guidance for dealing with our patients who have acute and chronic kidney disease, including those on renal replacement therapy and the staff involved in their care. Emphasis is placed on preparedness and prevention strategies. As evidence and experience accumulate, it is likely that updated guidance will be needed.L’Afrique suit le reste du monde en termes de nombre de cas et de décès dus à COVID-19.

Increasing access to integrated ESKD care as part of Universal Health Coverage

The global nephrology community recognizes the need for a cohesive strategy to address the growing problem of end-stage kidney disease (ESKD). In March 2018, the International Society of Nephrology hosted a summit on integrated ESKD care, including 92 individuals from around the globe with diverse expertise and professional backgrounds. The attendees were from 41 countries, including 16 participants from 11 low- and lower-middle–income countries. The purpose was to develop a strategic plan to improve worldwide access to integrated ESKD care, by identifying and prioritizing key activities across 8 themes: (i) estimates of ESKD burden and treatment coverage, (ii) advocacy, (iii) education and training/workforce, (iv) financing/funding models, (v) ethics, (vi) dialysis, (vii) transplantation, and (viii) conservative care. Action plans with prioritized lists of goals, activities, and key deliverables, and an overarching performance framework were developed for each theme. Examples of these key deliverables include improved data availability, integration of core registry measures and analysis to inform development of health care policy; a framework for advocacy; improved and continued stakeholder engagement; improved workforce training; equitable, efficient, and cost-effective funding models; greater understanding and greater application of ethical principles in practice and policy; definition and application of standards for safe and sustainable dialysis treatment and a set of measurable quality parameters; and integration of dialysis, transplantation, and comprehensive conservative care as ESKD treatment options within the context of overall health priorities. Intended users of the action plans include clinicians, patients and their families, scientists, industry partners, government decision makers, and advocacy organizations. Implementation of this integrated and comprehensive plan is intended to improve quality and access to care and thereby reduce serious health-related suffering of adults and children affected by ESKD worldwide

Status of care for end stage kidney disease in countries and regions worldwide:international cross sectional survey

ObjectiveTo determine the global capacity (availability, accessibility, quality, and affordability) to deliver kidney replacement therapy (dialysis and transplantation) and conservative kidney management.DesignInternational cross sectional survey.SettingInternational Society of Nephrology (ISN) survey of 182 countries from July to September 2018.ParticipantsKey stakeholders identified by ISN's national and regional leaders.Main outcome measuresMarkers of national capacity to deliver core components of kidney replacement therapy and conservative kidney management.ResultsResponses were received from 160 (87.9%) of 182 countries, comprising 97.8% (7338.5 million of 7501.3 million) of the world's population. A wide variation was found in capacity and structures for kidney replacement therapy and conservative kidney management-namely, funding mechanisms, health workforce, service delivery, and available technologies. Information on the prevalence of treated end stage kidney disease was available in 91 (42%) of 218 countries worldwide. Estimates varied more than 800-fold from 4 to 3392 per million population. Rwanda was the only low income country to report data on the prevalence of treated disease; 5 (<10%) of 53 African countries reported these data. Of 159 countries, 102 (64%) provided public funding for kidney replacement therapy. Sixty eight (43%) of 159 countries charged no fees at the point of care delivery and 34 (21%) made some charge. Haemodialysis was reported as available in 156 (100%) of 156 countries, peritoneal dialysis in 119 (76%) of 156 countries, and kidney transplantation in 114 (74%) of 155 countries. Dialysis and kidney transplantation were available to more than 50% of patients in only 108 (70%) and 45 (29%) of 154 countries that offered these services, respectively. Conservative kidney management was available in 124 (81%) of 154 countries. Worldwide, the median number of nephrologists was 9.96 per million population, which varied with income level.ConclusionsThese comprehensive data show the capacity of countries (including low income countries) to provide optimal care for patients with end stage kidney disease. They demonstrate substantial variability in the burden of such disease and capacity for kidney replacement therapy and conservative kidney management, which have implications for policy

Chronic kidney disease in sugarcane workers in Cameroon: a cross-sectional study

Abstract Background Agricultural workers especially in sugarcane plantations have a high risk of chronic kidney disease (CKD). Little is known about CKD among sugarcane plantation workers in Cameroon. This study sought to evaluate the prevalence and identify factors associated with CKD in sugarcane plantation workers in Cameroon. Methods We conducted an analytic cross-sectional study including 204 adult workers at the sugarcane plantation complex in Mbandjock, Cameroon; over 500 m above sea level. Chronic kidney disease (proteinuria as estimated by urine dipstick analysis and/or estimated glomerular filtration rate < 60 ml/min/1.73 m2 persistent after 3 months) was the outcome of interest. Those with abnormal results were seen again after 3 months to confirm the diagnosis. We evaluated the association between CKD and participant age, sex, contract-type, duration of employment, socio-economic status, workspace, exposure to agrochemicals, heavy metals and heat, selected risk factors and co-morbid conditions. Results The overall prevalence of CKD was 3.4%. The factory workers were the most affected (7%), compared to the field (2.4%) and office workers (0%). 2.9% of the participants had persistent proteinuria, mild in every case, and 0.5% of them had an estimated glomerular filtration rate < 60 ml/min/1.73 m2. Age ≥ 40 years was an independent predictor of CKD. Conclusion The prevalence of CKD among employees of the Mbandjock sugarcane plantation is low, probably reflecting the preventive measures against heat stress and dehydration in place

Incidence, characteristics and prognosis of acute kidney injury in Cameroon: a prospective study at the Douala General Hospital

Objective: There are limited data on AKI in sub-Saharan Africa. We aim to determine the incidence, characteristics and prognosis of AKI in Cameroon. Patients and methods: A prospective study including all consenting acute admissions in the internal medicine and the ICU of a tertiary referral hospital in Cameroon from January 2015 to June 2016. Serum creatinine assay was done on admission, days 2 and 7 to diagnose AKI. For patients with AKI, serum creatinine was done on discharge, days 30, 60 and 90. AKI was defined according to the modified KDIGO 2012 criteria as an increase or decrease in serum creatinine of 3 mg/l or greater, or an increase of 50% or more from the reference value obtained at admission or the known baseline value. AKI severity was graded using KDIGO2012 criteria. Outcome measures were renal recovery, mortality and causes of death. Renal recovery was complete if serum creatinine between the first 90 days was less than baseline or reference, partial if less than diagnosis but not baseline or reference, no-recovery if creatinine did not decrease or if the patient remained on dialysis. Results: Of the 2402 patients included, 536 developed AKI giving a global incidence of 22.3% and annual incidence of 15 per 100 patients-years. Of the 536 patients with AKI, 43.3% were at stage 3, 54.7% were males, median age was 56 years. Pre-renal AKI (61.4%) and acute tubular necrosis (28.9%) were the most frequent forms. Main etiologies were sepsis (50.4%) and volume depletion (31.6%). Renal outcome was unknown in 34% of patients. Of the 354 patients with known renal function at 3 months, 84.2% recovered completely, 14.7% partially and 1.1% progressed to CKD. Global mortality rate was 36.9% mainly due to sepsis. Conclusions: AKI is frequent in our setting, mainly due to sepsis and hypovolemia. It carries a poor prognosis

Complications of chronic kidney disease: current state, knowledge gaps, and strategy for action

The International Society of Nephrology has adopted a proactive approach to defining the current state of kidney care and unmet needs through a multifaceted Closing the Gaps initiative. As part of this initiative, the International Society of Nephrology convened a meeting of experts to develop an approach to tackle acute kidney injury and chronic kidney disease (CKD). This manuscript expands on the recently published International Society of Nephrology CKD Roadmap and reports on the discussions of the working group assigned to the task of reviewing the global impact of complication of CKD. The working group defined the following goals: Goal 1: Optimize the management of anemia and endocrine and metabolic abnormalities associated with CKD. The impact of these conditions at a global level is not well understood, particularly in regions where renal replacement therapy is not readily available. Some treatment regimens may be affordable in low- and middle-income countries and if implemented, could have an impact on the burden of suffering associated with CKD. Goal 2: Improve the prevention and management of cardiovascular complications linked to CKD. Most research on cardiovascular complications of CKD has focused on atherosclerotic diseases (myocardial infarction, ischemic stroke, and peripheral gangrene). There has been growing recognition that other forms of cardiovascular diseases, such as heart failure, valvular disease and arrhythmias, have a major impact on patient outcomes. Much less is known about the mechanisms and treatment of these non-atherosclerotic complications. Goal 3: Improve the diagnosis and management of symptoms associated with CKD. Symptom management is one of the greatest challenges in the management of CKD, with limited knowledge about the mechanisms associated with the development of these common problems and how best to characterize them into usable clinical phenotypes. Improved understanding of the complications of CKD may alleviate suffering and prolong life among millions of people worldwide both in developed countries and in regions where renal replacement therapy is not widely available

Closing the gap between evidence and practice in chronic kidney disease

There are major gaps between our growing knowledge of effective treatments for chronic kidney disease (CKD), and the delivery of evidence-based therapies to populations around the world. Although there remains a need for new, effective therapies, current evidence suggests that many patients with CKD are yet to fully realize the benefits of blood pressure-lowering drugs (with and without reducing proteinuria with renin-angiotensin system blockade), wider use of statins to reduce atherosclerotic cardiovascular disease events, and better glycemic control in both type 1 and type 2 diabetes. There are many barriers to optimizing evidence-based nephrology care around the world, including access to health care, affordability of treatments, consumer attitudes and circumstances, the dissemination of appropriate knowledge, the availability of expertise and structural impediments in the delivery of health care. Further investment in implementation science that addresses the major barriers to effective care in a cost-effective manner could yield both local and global benefits
