Advances in Hemodialysis in the Last Decade in Latin America.

UNASSIGNED: Kidney replacement therapy (KRT) initiated in Latin America towards the second half of the 20th century, starting with dialytic therapies and, shortly thereafter, with kidney transplant. By the end of 2021, close to half a million Latin Americans were under KRT, with an overall unadjusted prevalence of 872 per million persons (pmp), yet with significant heterogeneity between nations. By treatment modality, 68% of prevalent patients were treated with hemodialysis (HD), 9% with peritoneal dialysis (PD), and 23% were living with a functioning kidney graft (LFG). In the last decade, HD is the KRT that has had the largest growth, and it also has incorporated newer and better technologies. Nevertheless, Latin America shows heterogeneity between countries, and as a region we are far from achieving full accessibility to all in need of KRT. While there has been growth and improvement in existing renal dialysis registries, and several countries that did not previously have these registries have implemented them, there are still some nations with limited or absent registry implementation. The number of nephrologists in the region is heterogeneous, with only four countries having an appropriate group of specialists. The remaining nations have an important need to expand nephrology training programs. SLANH is a major regional player in addressing these topics and supporting the expansion of appropriate nephrology programs to improve inequalities and patient care.

International Society of Nephrology Global Kidney Health Atlas: structures, organization, and services for the management of kidney failure in Latin America.

Latin America is a region with a widely variable socioeconomic landscape, facing a surge in noncommunicable diseases, including chronic kidney disease and kidney failure, exposing significant limitations in the delivery of care. Despite region-wide efforts to explore and address these limitations, much uncertainty remains as to the capacity, accessibility, and quality of kidney failure care in Latin America. Through this second iteration of the International Society of Nephrology Global Kidney Health Atlas, we aimed to report on these indicators to provide a comprehensive map of kidney failure care in the region. Survey responses were received from 18 (64.2%) countries, representing 93.8% of the total population in Latin America. The median prevalence and incidence of treated kidney failure in Latin America were 715 and 157 per million population, respectively, the latter being higher than the global median (142 per million population), with Puerto Rico, Mexico, and El Salvador experiencing much of this growing burden. In most countries, public and private systems collectively funded most aspects of kidney replacement therapy (dialysis and transplantation) care, with patients incurring at least 1% to 25% of out-of-pocket costs. In most countries, >90% of dialysis patients able to access kidney replacement therapy received hemodialysis (n = 11; 5 high income and 6 upper-middle income), and only a small minority began with peritoneal dialysis (1%-10% in 67% of countries; n = 12). Few countries had chronic kidney disease registries or targeted detection programs. There is a large variability in the availability, accessibility, and quality of kidney failure care in Latin America, which appears to be subject to individual countries' funding structures, underreliance on cheap kidney replacement therapy, such as peritoneal dialysis, and limited chronic kidney disease surveillance and management initiatives.

Burden of disease: Closing the gaps in the burden of end-stage kidney disease in Latin America.

End-stage kidney disease (ESKD) represents a major challenge for Latin America (LA). The Latin American Dialysis and Renal Transplantation Registry (LADRTR) has published several reports, and its continuity has implied a sustained effort of the nephrology community to improve care of ESKD in the region; this paper summarizes results of the year 2014. Methods have been reported previously; participant countries complete annual surveys collecting data on incident and prevalent patients undergoing renal replacement therapy (RRT) in all modalities. 20 countries participated in the surveys (more than 90% of the region). Prevalence of treated ESKD in RRT increased from 119 patients per million population (pmp) in 1991 to 709 pmp in 2014; hemodialysis continues to be the treatment of choice in the region (68%). A wide variation was observed in the incidence rate, from 421 pmp in Jalisco (Mexico) to 23 pmp in Paraguay; diabetes was the cause of 36% of incident cases. Additionally, great heterogeneity was observed in the number of nephrologists by country, from 2 pmp in Colombia to 53 pmp in Uruguay. Heterogeneity, or even absence of registries in some LA countries, is concordant with inequities in RRT access as well as with the limited availability of qualified personnel. The LADRTR is leading the personnel training to develop and strengthen national dialysis and transplant registries in LA within the frame of the Pan-American Health Organization (PAHO) - Sociedad Latinoamericana de Nefrología e Hipertension (SLANH) cooperation program.

Latin American Dialysis and Transplant Registry: 2008 prevalence and incidence of end-stage renal disease and correlation with socioeconomic indexes.

In 2008, 563,294,000 people were living in Latin America (LA), of which 6.6% were older than 65. The region is going through a fast demographic and epidemiologic transition process, in the context of an improvement in socio-economic indices. The Latin American Dialysis and Renal Transplant Registry has collected data since 1991, through an annual survey completed by 20 affiliated National Societies. Renal replacement treatment (RRT) prevalence and incidence showed an increase year by year. The prevalence rate (in all modalities) correlated with the World Bank country classification by income and the epidemiologic transition stage the countries were experiencing. RRT prevalence and kidney transplantation rates correlated significantly with gross national income (GNI), health expenditure in constant dollars (HeExp), % older than 65, life expectancy at birth, and % of the population living in urban settings. Kidney transplantation increased also, year by year, with more than 50% of transplants performed using kidneys from deceased donors. Double transplants were performed in six countries. RRT prevalence and incidence increased in LA, and are associated with indexes reflecting higher and more evenly distributed national wealth (GNI and HeExp), and the stage of demographic and epidemiological transition.
