The South Asia region is facing a high burden of chronic kidney disease (CKD) with limited health resources and low expenditure on health care. In addition to the burden of CKD and kidney failure from traditional risk factors, CKD of unknown etiologies from India and Sri Lanka compounds the challenges of optimal management of CKD in the region. From the third edition of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA), we present the status of CKD burden, infrastructure, funding, resources, and health care personnel using the World Health Organization’s building blocks for health systems in the ISN South Asia region. The poor status of the public health care system and low health care expenditure resulted in high out-of-pocket expenditures for people with kidney disease, which further compounded the situation. There is insufficient country capacity across the region to provide kidney replacement therapies to cover the burden. The infrastructure was also not uniformly distributed among the countries in the region. There were no chronic hemodialysis centers in Afghanistan, and peritoneal dialysis services were only available in Bangladesh, India, Nepal, Pakistan, and Sri Lanka. Kidney transplantation was not available in Afghanistan, Bhutan, and Maldives. Conservative kidney management was reported as available in 63% (n = 5) of the countries, yet no country reported availability of the core CKM care components. There was a high hospitalization rate and early mortality because of inadequate kidney care. The lack of national registries and actual disease burden estimates reported in the region prevent policymakers’ attention to CKD as an important cause of morbidity and mortality. Data from the 2023 ISN-GKHA, although with some limitations, may be used for advocacy and improving CKD care in the region.

Purpose:Chronic kidney disease of uncertain etiology (CKDu) is an environmental nephropathy in which the etiological factors are yet uncertain. Leptospirosis, a spirochetal infection that is common among agricultural communities, has been identified as a potential etiology for CKDu beyond environmental nephropathy. Although CKDu is a chronic kidney disease, in endemic regions, an increasing number of cases are reported with features suggestive of acute interstitial nephritis without any known reason (AINu), with or without background CKD. The study hypothesizes that exposure to pathogenic leptospires is one of the causative factors for the occurrence of AINu. Method:This study was carried out using 59 clinically diagnosed AINu patients, 72 healthy controls from CKDu endemic region (endemic controls [ECs]), and 71 healthy controls from CKDu non-endemic region (non-endemic controls [NECs]). Results:The seroprevalence of 18.6, 6.9, and 7.0% was observed in the AIN (or AINu), EC, and NEC groups, respectively, from the rapid IgM test. Among 19 serovars tested, the highest seroprevalence was observed at 72.9, 38.9, and 21.1% in the AIN (AINu), EC, and NEC groups, respectively, by microscopic agglutination test (MAT), particularly for serovar Leptospira santarosaiserovar Shermani. This emphasizes the presence of infection in AINu patients, and this also suggests that Leptospiraexposure might play an important role in AINu. Conclusion:These data suggest that exposure to Leptospirainfection could be one of the possible causative factors for the occurrence of AINu, which may lead to CKDu in Sri Lanka.

The development of peritoneal dialysis (PD) programmes in lower-resource countries is challenging. This article describes the learning points of establishing PD programmes in three countries in South Asia (Nepal, Sri Lanka and Pakistan). The key barriers identified were government support (financial), maintaining stable supply of PD fluids, lack of nephrologist and nurse expertise, nephrology community bias against PD, lack of nephrology trainee awareness and exposure to this modality. To overcome these barriers, a well-trained PD lead nephrologist (PD champion) is needed, who can advocate for this modality at government, professional and community levels. Ongoing educational programmes for doctors, nurses and patients are needed to sustain the PD programmes. Support from well-established PD centres and international organisations (International Society of Peritoneal Dialysis (ISPD), International Society of Nephrology (ISN), International Pediatric Nephrology Association (IPNA) are essential.

Background Despite growing need, treatment for end-stage renal disease is limited in low- and middle-income countries due to resource restraints. We describe the development of an educational curriculum and quality improvement program to support continuous ambulatory peritoneal dialysis (CAPD) performed primarily by non-nephrology providers in Sri Lanka.Methods We developed a program of education, outcome tracking, and expert consultation to support providers in Kandy, Sri Lanka. Education included videos and in-person didactics covering core topics in CAPD. Event-tracking sheets recorded root causes and management of infections and hospitalizations. Conferences reviewed clinical cases and overall clinic management. We evaluated the patient census, peritonitis rates, and root causes and management of infections over 1 year.Results The curriculum was published through the International Society of Nephrology online academy. High provider turnover limited curriculum assessments. The CAPD patient census rose from 63 to 116 during the year. The peritonitis rate declined significantly, from 0.8 episodes per patient-year in the first 6 months to 0.4 in the latter 6 months, though the most common root causes of peritonitis, related to contamination events and hygiene, persisted. The appropriate ascertainment of culture data and prescription of antibiotics also increased.Conclusions Our project supported the expansion of a CAPD program in a resource-limited setting, while also improving peritonitis outcomes. Ongoing challenges include ensuring a durable educational system for rotating providers, tracking outcomes beyond peritonitis, and formalizing management protocols. Our program can serve as an example of how established dialysis programs can support the burgeoning work of providers in resource-limited setting.
