RESUMEN
Peritoneal dialysis (PD) is a well-established modality for kidney replacement therapy (KRT) globally, offering benefits such as better preservation of residual kidney function, improved quality of life, and reduced resource requirements. Despite these advantages, the global utilization of PD remains suboptimal, particularly in South Asia (SA), where a significant gap in PD delivery exists. This study aims to uncover the perceived barriers hindering PD utilization among nephrologists in SA. This is a cross-sectional survey involving 732 nephrologists from SA region. . The majority of respondents (44.7%) reported initiating less than six PD cases annually, reflecting low PD utilization. Cost and financial reimbursement policies emerged as major barriers, with 44.3% considering PD more expensive than haemodialysis (HD). Accessibility, negative attitudes toward PD, and fear of complications were identified as critical factors influencing PD adoption. The study also highlighted variations in PD costs among SA countries, emphasizing the need for tailored health economic strategies. This analysis provides insights into the multifaceted challenges faced by SA nephrologists in promoting PD and underscores the importance of targeted interventions.
RESUMEN
INTRODUCTION: Therapeutic plasma exchange (TPE) is used to manage various life-threatening illnesses. It is widely performed by nephrologists, intensivists, pathologists, or experts in transfusion medicine worldwide. However, the costs of TPE sessions are exceedingly high, and they have a huge impact on patients' financial burden. Herein, we investigated the outcomes of the reuse of plasma filters in TPE on several occasions. METHODS: This is a retrospective analysis of patients receiving TPE from January 1, 2020, to April 30, 2023, in the Department of Nephrology. A formulation of 4.5% peracetic acid and 24% hydrogen peroxide acid with RO water dilution was used for reprocessing. Clinical outcomes, risks, and cost-benefit were evaluated and compared between the plasma filter reuse group (GP-1) and the no-reuse group (GP-2). RESULTS: A total of 70 patients were included in this study. 200 and 112 TPE sessions were performed in GP-1 and GP-2, respectively. The most common indication for TPE in both groups was neurological. The clinical efficacy of TPE was similar in both groups. There was no difference in the clotting of the plasma filter, any allergic reaction, infection, or bleeding in the group. However, there was a significant difference in levels of fibrinogen (p=0.03) pre and post-procedure in both groups. The incidence of hypotension was found to be higher in GP-1 (26%) compared to GP-2 (15.6%), p = 0.05. The cost of overall treatment was 38% less in GP-1. CONCLUSION: The reuse of plasma filters is a safe and effective method for cost minimization in patients requiring TPE. This method can be effectively utilized in resource-poor settings without any increased risk of adverse effects.
RESUMEN
INTRODUCTION: Snakebite is a public health problem leading to about 58,000 deaths every year in India. Kidney injury subsequent to snakebite envenomation is common with a reported prevalence of up to 32%. The current study aims to elucidate the spectrum of kidney histopathology in acute kidney injury (AKI) cases associated with snake bites. METHODS: We searched seven electronic database studies to identify studies describing the histopathological findings in the kidney with snakebite envenomation. Two reviewers independently conducted titles and abstract screening as well as full-text evaluation for the final inclusion decision. Data were extracted as per the standardized form. We conducted narrative synthesis. Studies done exclusively on autopsy findings, in vitro studies, and case reports were excluded. RESULTS: We retrieved 1464 studies and finally included 28 studies which met the eligibility criteria in the analysis. Most studies were single-centre and the majority were cross-sectional. Overall we included a total of 534 renal biopsies. Russell's viper bite was the most common cause related to AKI. Acute tubular necrosis was the most common finding followed by acute interstitial nephritis, acute cortical necrosis (ACN), and thrombotic microangiopathy (TMA). Vasculitis changes in vessels were rarely reported. Lesions such as ACN and TMA were associated with poor outcomes. CONCLUSION: This analysis supports the notion that renal biopsies are important to guide prognosis and increase our knowledge about post-snake bite AKI pathophysiology.

Background and Aim: Primary glomerular disease accounts for one-sixth of all chronic kidney diseases (CKDs) in India. We remain limited in our ability to effectively treat these conditions because of lack of understanding of the disease mechanisms and lack of predictors to identify the clinical course and therapeutic responsiveness. We propose to develop a network of investigators in glomerular diseases, collect information in a systematic fashion to understand the clinical outcomes, answer translational research questions better, and identify and recruit patients for clinical trials. Materials and Methods: This is a prospective, observational study. The Indian TrANslational GlomerulonephrItis BioLogy nEtwork (I-TANGIBLE) cohort will enroll patients (>18 years) with biopsy-proven minimal change disease (MCD), focal segmental glomerulonephritis (FSGS), membranous nephropathy (MN), IgA nephropathy (IgAN), or membranoproliferative glomerulonephritis (MPGN) (immune complex- and complement-mediated), with first biopsy taken within 2 years of enrollment. Patients with estimated glomerular filtration (eGFR) rate <15 ml/min/1.73 m2 for >3 months at the time of screening, kidney transplant or bone marrow transplant recipients, patients with active malignancy, and patients with active hepatitis B/C replication or human immunodeficiency virus (HIV)-I/II will be excluded. Clinical details including history, medication history and details, and family history will be obtained. Consenting patient's blood and urine samples will be collected and stored, aligned to their clinical follow-up. Expected Outcomes: The network will allow accurate ascertainment of disease burden of glomerular diseases across study sites, establishment of the treatment pattern of common glomerular diseases, investigation of medium- and long-term outcomes (remission, relapse, rate of eGFR decline), and building a suitable infrastructure to carry out clinical trials in primary glomerular disease.
RESUMEN
There is a direct and accelerating connection between ongoing environmental change, the unprecedented decline in biodiversity, and the increase in infectious disease epidemiology worldwide. Rising global temperatures are threatening the biodiversity that underpins the richness and diversity of flora and fauna species in our ecosystem. Anthropogenic activities such as burning fossil fuels, deforestation, rapid urbanization, and expanding population are the primary drivers of environmental change resulting in biodiversity collapse. Climate change is influencing the emergence, prevalence, and transmission of infectious diseases both directly and through its impact on biodiversity. The environment is gradually becoming more suitable for infectious diseases by affecting a variety of pathogens, hosts, and vectors and by favoring transmission rates in many parts of the world that were until recently free of these infections. The acute effects of these zoonotic, vector and waterborne diseases are well known; however, evidence is emerging about their role in the development of chronic kidney disease. The pathways linking environmental change and biodiversity loss to infections impacting kidney health are diverse and complex. Climate change and biodiversity loss disproportionately affect the vulnerable and limit their ability to access healthcare. The kidney health community needs to contribute to the issue of environmental change and biodiversity loss through multisectoral action alongside government, policymakers, advocates, businesses, and the general population. We describe various aspects of the environmental change effects on the transmission and emergence of infectious diseases particularly focusing on its potential impact on kidney health. We also discuss the adaptive and mitigation measures and the gaps in research and policy action.
RESUMEN
Shortage of organ donors is the most important obstacle standing in the way of lifesaving organ transplantation in a myriad of patients suffering from end-stage organ failure. It is vital that the transplant societies and associated appropriate authorities develop strategies to overcome the unmet needs for organ donation. The power of prominent social media (SoMe) platforms such as Facebook, Twitter, and Instagram, which reach millions of people, can increase awareness, provide education, and may ameliorate the pessimism toward organ donation among the general population. Additionally, public solicitation of organs may be helpful for waitlisted candidates for organ transplantation, who cannot find a suitable donor among near relations. However, the use of SoMe for organ donation has several ethical issues. This review attempts to highlight the advantages and limitations of using social media in the context of organ donation for transplantation. Some suggestions on the best utilization of social media platforms for organ donation while balancing ethical considerations have been highlighted here.
RESUMEN
Hyponatremia is one of the most common problems encountered in clinical practice and one of the least-understood because accurate diagnosis and management require some familiarity with water homeostasis physiology, making the topic seemingly complex. The prevalence of hyponatremia depends on the nature of the population studied and the criteria used to define it. Hyponatremia is associated with poor outcomes including increased mortality and morbidity. The pathogenesis of hypotonic hyponatremia involves the accumulation of electrolyte-free water caused by either increased intake and/or decrease in kidney excretion. Plasma osmolality, urine osmolality, and urine sodium can help to differentiate among the different etiologies. Brain adaptation to plasma hypotonicity consisting of solute extrusion to mitigate further water influx into brain cells best explains the clinical manifestations of hyponatremia. Acute hyponatremia has an onset within 48 hours, commonly resulting in severe symptoms, while chronic hyponatremia develops over 48 hours and usually is pauci-symptomatic. However, the latter increases the risk of osmotic demyelination syndrome if hyponatremia is corrected rapidly; therefore, extreme caution must be exercised when correcting plasma sodium. Management strategies depend on the presence of symptoms and the cause of hyponatremia and are discussed in this review.

INTRODUCTION: Thromboembolism is more common in kidney transplant recipients (KTRs) than in the general population. Studies evaluating arterial and venous thromboembolism (VTE) in KTRs are scarce and the magnitude and risk factors are mostly undefined. METHODS: A nested control study was conducted from January 1, 2007, to December 31, 2019. Adult KTRs who were detected to have VTE events during this period were included. The primary outcome was to assess the prevalence of VTE in this population. Secondary outcomes were the assessment of the time to occurrence of the thromboembolic events after transplantation and assessing the risk factors and patient survival. For each subject studied, 4 controls were matched from the data set. RESULTS: Amongst 2158 patients, 97 (4.5%) were found to have VTE. The median follow-up time was 3.9 years (6-156 months). A total of 101 VTE events were recorded. The most common site of VTE was the lower limb deep vein thrombosis in 79 patients (0.03%)).In multivariate Cox regression analysis, serum creatinine of more than 3 mg/dl [HR 1.30, 95% CI (1.03-1.38)] was independently associated with increased VTE risk. Patients who developed a VTE had higher mortality as compared to patients who did not develop VTE. No increased risk of graft failure was found in VTE patients. CONCLUSION: This study suggests that kidney transplantation surgery is a moderate risk factor for VTE, and VTE is associated with higher morbidity and mortality. However, prospective studies are needed to establish a definite role of VTE in outcomes in KTRs.

The coronavirus disease (COVID-19) crisis glaringly highlighted the critical need to develop resilient health care systems that are better prepared for epidemics. Millions of people died from COVID-19 itself, but almost three times as many died from health system disruptions. People living with kidney disease are highly vulnerable during outbreaks and pandemics and their needs must be included in preparedness planning. Health systems preparedness requires not only early identification and containment of outbreaks and maintenance of critical services during crises, but also bolstering population resilience and ensuring the safety of both health personnel and patients. Planning for surge capacity in an outbreak must include provision for both acute and chronic dialysis, and ensure access to medications for people with kidney diseases. Quality of care should not be compromised and must be monitored and improved where necessary. Technology, such as telemedicine, can support quality and continuity of care and minimize infection risks. Communication at all levels is crucial to ensure all stakeholders, including communities, have the necessary information to support cooperation and collaboration in effective outbreak responses. Research is important during and after pandemics to improve knowledge and build resilience at all levels, from outbreak detection to the development of therapeutics and optimizing equity in access to interventions. Only with adequate preparation and more resilient health systems can we hope, as a global community, to build on the harsh lessons learned during COVID-19, and improve the response to the next infectious disease outbreak, epidemic, or even pandemic.

Cryptococcosis is the third most commonly occurring invasive fungal disease in solid organ transplant recipients (SOT). It is caused by encapsulated yeast, Cryptococcus species, predominantly Cryptococcus neoformans and Cryptococcus gattii. Though kidney transplant recipients are at the lowest risk of cryptococcosis when compared to other solid organ transplant recipients such as lung, liver or heart, still this opportunistic infection causes significant morbidity and mortality in this subset of patients. Mortality rates with cryptococcosis range from 10%-25%, while it can be as high as 50% in SOT recipients with central nervous system involvement. The main aim of diagnosis is to find out if there is any involvement of the central nervous system in disseminated disease or whether there is only localized pulmonary involvement as it has implications for both prognostication and treatment. Detection of cryptococcal antigen (CrAg) in cerebrospinal fluid or plasma is a highly recommended test as it is more sensitive and specific than India ink and fungal cultures. The CrAg lateral flow assay is the single point of care test that can rapidly detect cryptococcal polysaccharide capsule. Treatment of cryptococcosis is challenging in kidney transplant recipients. Apart from the reduction or optimization of immunosuppression, lipid formulations of amphotericin B are preferred as induction antifungal agents. Consolidation and maintenance are done with fluconazole; carefully monitoring its interactions with calcineurin inhibitors. This review further discusses in depth the evolving developments in the epidemiology, pathogenesis, diagnostic assays, and management approach of cryptococcosis in kidney transplant recipients.
RESUMEN
The process of learning has been confined to the realms of educational institutions. Over the last ten years, the semantics of social media networks have evolved with the use of mobile gadgets. Consequently, nephrologists have realised the potential benefits of using these platforms for their educational and career development. Social media can change the horizon of nephrology education. The concept of bedside examination, teaching and sharing experiences have changed with the advent of Facebook, YouTube, Instagram and X (former Twitter). Other networking portals, such as WhatsApp, Telegram, X (former Twitter), and Pinterest, have also amassed the attention of selected users. Despite split opinions on the utility of social media, it is undeniable that it has influenced interaction between students and mentors. Resources ranging from online networks, blogs, visual aids, podcasts, online journal clubs, videos, live conference coverages, and tutorials have made it possible for nephrologists to stay informed and educated with recent updates. In this review, we discuss how social media can enrich nephrology academia, facilitate the sharing of research and access to fellowships and mentorship programs, provide career prospects to trainees, and broadcast scientific conferences while bringing nephrology societies together. Keywords: education; nephrology; social media.

INTRODUCTION: Early-start peritoneal dialysis (PD) (use of PD catheter within 48 hours of insertion) is an innovative approach for prompt initiation of PD. AIM: This study was conducted to analyze the outcomes of early-start PD. MATERIALS AND METHODS: A total of 100 patients on PD were retrospectively analyzed. Patients were grouped according to the "break-in period": < 48 hours (PD1) and ≥ 14 days (PD2). PD was initiated with low dwell volumes (500 mL) in a recumbent position within 48 hours of surgery. PD prescription was gradually incremented over 10 days to minimize any complications. RESULTS: In our study, there were 48 patients in the PD1 group and 52 in the PD2 group. The most common cause of end-stage kidney disease (ESKD) was diabetes mellitus in both groups. Incidence of early mechanical complications (within 30 days of catheter insertion), such as catheter obstruction, early catheter leakage, catheter malposition, tip migration, and infectious complications, were not found to be higher in the PD1 group. 1- and 4-year catheter patency rates were 97.0% and 96.2% in the PD1 group, respectively. These rates were comparable with those in the PD2 group. Early-start PD was not associated with an increased incidence of catheter failure (HR = 1.0, 95% CI 0.28 - 3.47). CONCLUSION: An early break-in period of < 48 hours is a feasible option for ESKD patients without any significantly increased risk of mechanical or infectious complications. It offers a safe and efficacious option for renal replacement therapy.
