Current status of end-stage renal disease care in India and Pakistan

One Nation-One Dialysis: Breaking Barriers, Empowering Lives

The objective of India's One Nation One Dialysis (ONOD) program is to remove the barriers that end-stage kidney disease patients face in accessing consistent, quality dialysis services across the nation. A unified and standardized dialysis care approach is what ONOD aims to achieve at a national level. The objective of ONOD is to improve access to, affordability of, and quality in dialysis services for economically weaker segments of society and those living in remote areas of the country by providing dialysis services through public-private partnerships. The ONOD program places a lot of emphasis on the infrastructure development, funding support, skill development, regulatory reforms, and technological integration of dialysis services. By implementing ONOD, India can improve patient outcomes, close the supply-demand gaps for end-stage kidney disease kidney replacement therapy, and create a more balanced and sustainable kidney healthcare ecosystem.

Profiling mortality patterns and place of death in patients on maintenance hemodialysis: a retrospective study in a tertiary care academic hospital in India

BACKGROUND

End-stage kidney disease (ESKD) significantly burdens healthcare systems and increases mortality. In India, approximately 175,000 individuals are relying on maintenance hemodialysis (mHD). This study aims to analyze the place of death, mortality patterns and clinical issues surrounding death in patients with ESKD undergoing mHD at a tertiary care hospital in south India.

METHODS

This retrospective study reviewed the medical records of 280 patients with ESKD who underwent mHD between January 2016 and April 2022. Data were collected on demographics, financial details, comorbidities, cause of death, clinical issues, and location of death. Descriptive statistics, including means, frequencies, and proportions, were used to summarize findings.

RESULTS

Among the 280 patients on mHD, there were 98 deaths. Of these, 73.5% died in hospitals, primarily in intensive care units. Of all the patient deaths, 57.7% patients who died at home and 41.6% of hospitalized patients paid out of pocket treatment expenses. Infections and cardiovascular complications were the leading causes of death. High comorbidity and symptom burden were reported, with edema, fatigue, and breathlessness being the most common symptoms. Among the hospital deaths, withholding or withdrawing life sustaining treatments was documented in only 22.2% of cases.

CONCLUSIONS

Our study provides critical insights into mortality patterns and the need for improved kidney supportive care integration in patients with ESKD. Addressing symptom burden, enhancing ACP, and implementing end of life care protocols could align healthcare delivery with patient preferences, ultimately improving the quality of end of life care in this vulnerable population. Further research is recommended to explore broader interventions and their impact on patient outcomes.

Association between antenatal care visits and under-five mortality: An Analysis of the Pakistan demographic and health surveys

BACKGROUND

Pakistan has the third highest under-five mortality rate globally and minimal progress in reducing it, obstructing its achievement of Sustainable Development Goals (SDGs) 3.2 targets. Despite a decline, Pakistan remains one of the top ten contributors to worldwide under-five mortality. Proper antenatal care (ANC) is vital for improving maternal and child health outcomes. This study aims to assess the association between ANC visits and under-five mortality. Moreover, this study also measures the association between the timing of ANC visits and under-five mortality.

METHODS

A difference-in-difference (DID) study design with propensity score matching (PSM) was employed to investigate the contributing impact of ANC on the estimation of under-five mortality rates. Statistics from two datasets, 2012 and 2018, of Pakistan demographic and health surveys (PDHS) have been utilized for analyses. This research sample consists of 15698 women aged 15-49 who attended ANC visits at varying times before childbirth.

RESULTS

This study has reported 730 cases of under-five mortality. 98% involved Women who had less than eight or more ANC visits, whereas 2% of under-five mortality cases occurred among those women who had eight or more ANC visits. Overall, our results showed that women who had 1-3 ANC visits reduced the likelihood of under-five mortality in Pakistan by 36% (CI=0.459-0.909, P-value 0.012), the women who had 4-7 ANC visits decreased the likelihood of under-five mortality by 45% (CI=0.364-0.843, P-value 0.006). Moreover, the females with eight or more ANC visits also reduced the likelihood of under-five mortality by 98% (CI=0.512-1.896, P-value 0.966).

CONCLUSIONS

Policies and programs focusing more on ANC visits should be implemented to reduce under-five mortality rates significantly. By emphasizing timely and frequent ANC visits, these insights support the development of targeted interventions that can significantly improve child survival rates and support the achievement of SDG targets. Moreover, based on our DID analysis, the implementation of the free maternal and child healthcare (MCH) policy in Pakistan has led to a significant increase in ANC utilization and a consistent reduction in the under-five mortality rates.

Microbiological Quality of Reverse Osmosis Water of a Dialysis Unit: Analysis From a Tertiary Care Hospital in Imphal, India

Background Patients undergoing maintenance hemodialysis (HD) are exposed to large volumes of treated water, making its microbiological quality crucial for patient safety. Contaminated dialysis water can introduce microbial pathogens into the bloodstream, increasing the risk of pyrogenic reactions, sepsis, and chronic inflammation. Water quality monitoring remains a challenge in many healthcare settings despite its importance. This study evaluates the microbiological quality of treated water and dialysate used in a tertiary care hospital dialysis unit in Imphal, India. Methods This observational study was conducted at the Regional Institute of Medical Sciences, Imphal, from August 2021 to January 2025. A total of 84 water samples were collected from different points in the dialysis system, including product water, storage water, middle port water, and return water. Samples were processed using membrane filtration and analyzed for microbial contamination using culture-based methods and Vitek 2 Compact for species identification. The findings were assessed against the Association for the Advancement of Medical Instrumentation (AAMI) standards for dialysis water quality.  Results Microbiological analysis revealed varying contamination levels across different water sources. Product water exhibited the highest microbial presence, with Acinetobacter species being the most frequently detected organism. The most recent sample (January 2025) showed Aeromonas spp. and Acinetobacter spp. in product water. Some samples exceeded AAMI standards, with colony-forming unit (CFU) counts ranging from 104 to 274 CFU/100 mL in product water. Storage, middle port, and return water showed lower contamination levels. Out of the total 21 samples collected, unsatisfactory microbial growth was observed in three samples of product water and one sample of storage water as per AAMI standard, whereas no unsatisfactory growth was detected in any of the middle port water or return water samples. Acinetobacter baumannii was detected in all four water types, while other multidrug-resistant organisms, such as Klebsiella pneumoniae, were found in return water. Conclusion The study highlights fluctuating levels of microbial contamination in dialysis water, with Acinetobacter species being the predominant contaminant. Regular monitoring, stringent adherence to water treatment protocols, and strict infection control measures are essential to ensure dialysis water safety and improve patient outcomes.

Comprehensive Clinical Profile and Hemodialysis Outcomes in Patients Attending a Tertiary Care Hospital

Background Chronic kidney disease (CKD) can lead to serious conditions such as anemia and cardiovascular disease, posing a growing global health challenge. End-stage renal disease (ESRD) requires treatments such as dialysis or kidney transplantation. Despite the widespread impact and rising prevalence of CKD and ESRD, comprehensive data remains limited in India. This study seeks to investigate the clinical, socio-demographic, and etiological profiles of CKD patients undergoing hemodialysis at a tertiary care hospital, with the goal of enhancing understanding and improving patient care. Methodology This retrospective cohort study, conducted at a tertiary care center, included 500 CKD patients undergoing hemodialysis, with comprehensive medical records. Data collected covered demographics (age, sex, education, and occupation), CKD etiology, disease duration, hemodialysis duration, viral marker status, blood transfusions, and vascular access details. With continuous variables reported as mean ± standard deviation (SD) and categorical variables as counts (percentages), statistical analysis was carried out using SPSS version 21 (IBM Corp., Armonk, New York, USA). The connections were examined using the Pearson Chi-square test, with P≤0.05 being deemed significant. Results The study revealed that hypertension was the primary cause of CKD in 58% of patients, followed by diabetes mellitus in 13%. A significant 93% of patients tested negative for viral markers such as human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B surface antigen (HBsAg). Hemodialysis duration varied, with 68% of patients undergoing dialysis for one to five years. Most patients had two (40%) or three (58%) dialysis sessions per week, and 84% had only one arteriovenous (AV) fistula surgery. Blood transfusions were common, with 62% of patients receiving between one and five transfusions. The gender distribution showed more males (372) than females (201), and the majority of patients were aged between 41 and 60 years. Conclusion This study highlights the importance of early detection and management of CKD, emphasizing preventive health measures, enhanced diagnostic capabilities, and sufficient resource allocation to reduce the disease burden. It also calls for further research into unknown CKD causes and strategies to improve patient care and outcomes.

Lived experiences of village-based patients with chronic kidney disease receiving haemodialysis at Mirpur, Azad Kashmir, Pakistan: a transcendental phenomenology study protocol

BACKGROUND

Chronic kidney disease (CKD) is one of the major health issues in Pakistan, exerting notable effects on both the physical and mental well-being of individuals undergoing haemodialysis. Of particular concern to healthcare professionals is the potential adverse influence of haemodialysis on the lives of patients with CKD residing in rural areas of the country. This study will explore and describe the lived experiences and needs of patients with CKD receiving haemodialysis from the perspectives of patients and their family caregivers.

METHODS AND ANALYSIS

Transcendental phenomenological research design will be used. Participants will be recruited from the dialysis centre of a tertiary hospital through purposive sampling based on specific inclusion criteria. In-depth unstructured interviews, observation and document analysis will be the methods for data collection. Data will be analysed using Colaizzi's approach following the transcription of the interviews.

ETHICS AND DISSEMINATION

The study has been approved by the Institutional Review Board (IRB) of Shifa Tameer-e-Millat University, Pakistan (IRB # 0307-23) and written permission was obtained from the administration of the study hospital. Before giving written and verbal consent, all participants will receive detailed information about the study. Participants will maintain the freedom to withdraw from the study at any point. Confidentiality of the participants will be ensured. The study findings will be disseminated to important stakeholders and published in scientific papers and conference proceedings.

Centre-level variation in the survival of patients receiving haemodialysis in India: findings from a nationwide private haemodialysis network

Background

There are no large studies examining survival in patients receiving haemodialysis in India or considering centre-level effects on survival. We measured survival variation between dialysis centres across India and evaluated the extent to which differences are explained by measured centre characteristics.

Methods

This is a multilevel analysis of patient survival in centres of the NephroPlus dialysis network consisting of 193 centres across India. Patients receiving haemodialysis at a centre for ≥90 days between April 2014 and June 2019 were included, with analyses restricted to centres with ≥10 such patients. The primary outcome was all-cause mortality, measured from 90 days after joining a centre. Proportional hazards models with shared frailty were used to model centre- and patient-level effects on survival.

Findings

Amongst 23,601 patients (median age 53 years; 29% female), the unadjusted centre-specific 180-day Kaplan-Meier survival estimates ranged between 55% (95% confidence interval [CI] 38-80%) and 100%, with a median of 88% (interquartile interval 83%-92%). After accounting for multilevel factors, estimated 180-day survival ranged between 83% (73-89%) and 97% (95-98%), with 90% 180-day survival in the average centre. The mortality rate in patients attending rural centres was 32% (Hazard Ratio 1.32; 95% CI 1.06-1.65) higher than those at urban centres in adjusted analyses. Multiple patient characteristics were associated with mortality.

Interpretation

This is the first national benchmark for survival amongst dialysis patients in India. Centre- and patient-level characteristics are associated with survival but there remains unexplained variation between centres. As India continues to widen dialysis access, ongoing quality improvement programs will be an important part of ensuring that patients experience the best possible outcomes at the point of care.

Systematic review of end stage renal disease in Pakistan: Identifying implementation research outcomes

AIM AND OBJECTIVES

The aim of this study was to conduct a systematic review analysis to identify and evaluate the available literature on implementation science outcomes research in relation to End Stage Renal Disease (ESRD) in Pakistan.

METHODS

A systematic database search of PubMed, Web of Science, EMBASE, Cochrane Library, CINAHL, and Ovid was conducted through October 22nd, 2022, without any restrictions on publication dates. A screening and data extraction tool, Covidence, was used to evaluate the literature against our inclusion and exclusion criteria. Furthermore, a Mixed Methods Appraisal Tool (MMAT) was used to evaluate the selected studies.

RESULTS

We identified four studies that presented findings of implementation outcomes research which were related to appropriateness, feasibility, and acceptability. Appropriateness was examined using knowledge scores (p = 0.022) and medication adherence scores (p < 0.05) that showed statistical significance between the control and intervention groups. Acceptability was assessed through a cross sectional quantitative descriptive study that evaluated the reasons for refusal and acceptance of treatment in a cohort of patients suffering from ESRD. Feasibility was examined in one cross sectional, and one mixed methods study that aimed to evaluate and understand the impact of initiating dialysis treatment and the feasibility of maintaining it in low-income families that care for children or adults with ESRD.

CONCLUSION

The preliminary results of this review indicate a gap in the availability of implementation research studies about ESRD in Pakistan. The burden of ESRD, and the implementation methods by which it is treated is notable in Pakistan and requires evidence-based measures to be implemented to support the critical healthcare delivery platforms that provide treatment.

Real-world data on renal transplantations from a tertiary-care hospital in North India, in context of Indian regulatory act-transplantation of human organs and tissues act (THOTA): A retrospective analysis

INTRODUCTION

Renal transplantation is the treatment of choice for patients suffering from end stage renal disease (ESRD). Indian regulations defined under Transplantation of Human Organs and Tissues Act (THOTA), 2014 restricts organ donations to near-related living donors to curb any malpractices like 'paid donors' in living-donor kidney transplantation (LDKT). The aim of our study was to look at real-world data of donor-recipient pairs and to identify relationship of donors (with their respective patients) and the common (or uncommon) DNA profiling methods used for supporting "claimed relationship" in accordance with the regulations.

MATERIAL AND METHODS

The donors were categorized and grouped into near-related donor, donors other than near-related donors, swap donors and deceased donors. Claimed relationship was confirmed, commonly by HLA typing, using SSOP method. In few cases, which were uncommon (and infrequent), autosomal DNA analysis, mitochondrial DNA analysis and Y-STR DNA analysis were performed to support the claimed relationship. Data collected included age, gender, relationship, DNA profiling test method.

RESULTS

Among the 514 donor-recipient pairs evaluated, numbers of female donors out-numbered male donors. The decreasing order of relationships in near-related donor group were wife>mother>father>sister>son>brother>husband> daughter>grandmother. 11.9% of donors were in the category of donors other than near-related donors. In 97.86% cases, the claimed relationship was supported by HLA typing and in just 2.1% cases autosomal DNA analysis>mitochondrial DNA analysis> Y-STR DNA analysis, in this order, were performed to establish relationship.

CONCLUSION

This study brought out gender disparity with women out-numbering men as donors. Among recipients, access to renal transplant was largely restricted to men. As far as relationship of donors to recipients was concerned, mostly near-related family members, like wife, were donors and claimed relationship was almost always (99%) was corroborated by HLA typing.

Di-(2-ethylhexyl) Phthalate Limits the Lipid-Lowering Effects of Simvastatin by Promoting Protein Degradation of Low-Density Lipoprotein Receptor: Role of PPARγ-PCSK9 and LXRα-IDOL Signaling Pathways

Dialysis prevents death from uremia in patients with end-stage renal disease (ESRD). Nevertheless, during hemodialysis, circulating levels of di-(2-ethylhexyl) phthalate (DEHP) are increased due to phthalates leaching from medical tubes. Statins are an effective therapy for reducing the risks associated with cardiovascular diseases in patients with chronic kidney disease; however, the mechanism by which statins fail to reduce cardiovascular events in hemodialysis ESRD patients remains unclear. In this study, we investigated whether DEHP and its metabolites interfere with the lipid-lowering effect of statins in hepatocytes. In Huh7 cells, treatment with DEHP and its metabolites abolished the simvastatin-conferred lipid-lowering effect. Mechanistically, DEHP down-regulated the expression of low-density lipoprotein receptor (LDLR) and led to a decrease in LDL binding, which was mediated by the activation of the PPARγ-PCSK9 and LXRα-IDOL signaling pathways. Additionally, the NOX-ROS-TRPA1 pathway is involved in the DEHP-mediated inhibition of LDLR expression and LDL binding activity. Blockage of this pathway abrogated the DEHP-mediated inhibition in the LDLR expression and LDL binding of simvastatin. Collectively, DEHP induces the activation of the NOX-ROS-TRPA1 pathway, which in turn activates PPARγ-PCSK9- and LXRα-IDOL-dependent signaling, and, ultimately, diminishes the statin-mediated lipid-lowering effect in hepatocytes.

Utility and patient acceptance of telemedicine in nephrology

PURPOSE

There is an increasing burden of kidney diseases worldwide and access to specialist care is limited. Telemedicine, has been relatively less used in developing countries like India. The current study aims to assess the feasibility and acceptance of telenephrology services at our institute, a public hospital.

METHODS

A total of 150 patients were selected by stratified random sampling from the list of attendees who had undergone both in-person outpatient consultation and telenephrology consultation. Patient's attitude towards, and knowledge and acceptance of telenephrology services were evaluated.

RESULTS

The average age of the study cohort was 42.52 ± 15.1 years. More than one-third (39.3%) of our patients belonged to the lower middle socioeconomic class. The median distance traveled to reach our outpatient clinic was 113.5 km (3-2249 km). Patients reported lost workdays in 54.7% cases. The majority (95%) of patients managed to consult through teleservices successfully. Ninety percent of the patients gave a satisfaction score of 4 (out of 5) or above for their tele-consultation experience. The most important perceived benefit of teleconsultation was the reduced risk of infection (40.6%) followed by economic benefits (32%). The major disadvantage (36%) was the absence of physical examination. A combination of physical and telenephrology services was the option preferred by 84% of the patients.

CONCLUSION

In developing countries like India, with the majority of the population residing outside major cities and with limited medical access, telenephrology has a huge potential to provide quality nephrology care to the remotest parts of the country.

Energy conservation education intervention for people with end-stage kidney disease receiving haemodialysis (EVEREST): protocol for a cluster randomised control trial

INTRODUCTION

Multiple symptoms occur in people with kidney failure receiving haemodialysis (HD) and these symptoms have a negative impact on health-related quality of life (HRQoL). Fatigue, the most common symptom, is debilitating and difficult to manage. Educational interventions involving energy conservation strategies are helpful in reducing fatigue, however the effectiveness of energy conservation has not been previously studied in those receiving HD. The aim of this study is to evaluate the effectiveness of an energy conservation education intervention for people with end-stage kidney disease receiving HD (EVEREST trial).

METHODS AND ANALYSIS

A pragmatic cluster randomised control trial with repeated measure will be used. One hundred and twenty-six participants from tertiary level dialysis centre will be cluster randomised to the intervention and control group according to HD treatment day. The intervention group will receive usual care along with a structured energy conservation education programme over 12 weeks comprising three individual face-to-face educational intervention sessions, one booster session and a booklet. The control group will receive usual care from their healthcare providers and a booklet at the end of the study. The primary outcome is fatigue, and the secondary outcomes are other Chronic Kidney Disease (CKD) symptoms, occupational performance and HRQoL. Intention-to-treat analysis will occur and will include a change in primary and secondary outcomes.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Human Research Committee of the Griffith University and Nepal Health Research Council. The results of this research will be published and presented in a variety of forums.

Accessibility and quality of haemodialysis services in an urban setting in South India: a qualitative multiperspective study

OBJECTIVE

To explore the accessibility and quality of existing haemodialysis services in an urban setting.

SETTING

The study was conducted in Bangalore city, India.

PARTICIPANTS

A total of 28 stakeholders including 2 nephrologists, 7 duty doctors, 13 dialysis technicians and 6 patients on long-term haemodialysis were selected from 20 dialysis centres in Bangalore city.

DESIGN AND METHODS

Qualitative study using in-depth interviews. A thematic analysis was done using the Availability, Accessibility, Acceptability and Quality Framework of WHO and the Bruce's Quality of Care Framework.

RESULTS

The study found several gaps with regard to the access and quality of existing services for patients with end-stage kidney disease (ESKD). The charges for dialysis sessions across settings displayed a wide variance. Patients often started dialysis services in private and later shifted to government and non-governmental organisations-run centres and reduced the number of weekly dialysis sessions due to financial constraints. Most standalone dialysis centres did not have the facilities to manage any emergencies. Most centres did not admit patients with hepatitis or HIV. The quality of care in dialysis centres seemed to be variable and most centres were managed solely by dialysis technicians. There were no psychosocial interventions available to the patients irrespective of the settings. Cost-cutting practices such as employing underqualified technicians, reusing dialysis equipment and using substandard water for dialysis were common.

CONCLUSION

The study highlights the need for more financial and personnel investments in ESKD care in India to ensure optimal care for the growing patient population. The study points towards the need for comprehensive management practices, including diet counselling and psychosocial support. While there are comprehensive guidelines on the establishment and management of dialysis services, more policy attention needs to be on effective implementation of these, to ensure better accessibility and quality of existing services.

“Machine-Dependent”: The Lived Experiences of Patients Receiving Hemodialysis in Pakistan

This study aimed to explore the lived experiences of patients receiving maintenance hemodialysis in Pakistan. Purposive sampling was used to recruit 24 patients and six healthcare professionals, each participated in a semi-structured interview. Interpretive Phenomenological Analysis was used to analyze interviews’ data. Two superordinate themes, “The experience of hemodialysis” and “The conceptualizations of hemodialysis” as well as six sub-themes were identified. The experience of hemodialysis was related to, the implications of HD procedure on everyday life, social, cognitive, emotional, financial, and occupational influences. While all participants recognized the importance of hemodialysis for their survival, their conceptualizations of the treatment varied. Despite facing multiple challenges, optimism and independence were observed among participants. Stigma related to hemodialysis, and role adaptation, which appear unique to the Pakistani context, highlight a need for tailored interventions designed to enhance and maintain the mental health of patients receiving hemodialysis in Pakistan.

Syndemics at play: chronic kidney disease, diabetes and COVID-19 in Pakistan

Although coronavirus disease 2019 (COVID-19) is a pandemic, it has several specificities influencing its outcomes due to the entwinement of several factors, which anthropologists have called "syndemics". Drawing upon Singer and Clair's syndemics model, I focus on synergistic interaction among chronic kidney disease (CKD), diabetes, and COVID-19 in Pakistan. I argue that over 36 million people in Pakistan are standing at a higher risk of contracting COVID-19, developing severe complications, and losing their lives. These two diseases, but several other socio-cultural, economic, and political factors contributing to structured vulnerabilities, would function as confounders. To deal with the critical effects of these syndemics the government needs appropriate policies and their implementation during the pandemic and post-pandemic. To eliminate or at least minimize various vulnerabilities, Pakistan needs drastic changes, especially to overcome (formal) illiteracy, unemployment, poverty, gender difference, and rural and urban difference.

Prospective multi-centric study to analyze pre-transplant compatibility algorithm for live-related donor kidney transplant in Indian setting: the "Delhi approach"!

BACKGROUND

Since no single test is always accurate and sensitive, two or more tests are used to increase the precision of evaluation. Different algorithms have been proposed by centers in Leiden, Basel, Vienna and Minnesota, etc. With an intention to develop an optimal algorithm for India, we evaluated pre-transplant compatibility tests for live-donor kidney transplants. Three tests complement dependent cyto-toxicity cross-match (CDCXM), flow-cytometry cross-match (FCXM) and anti-HLA antibody screening (HAS) were performed and confirmed by the anti-HLA antibody identification (HAI) assay in a multi-centric trial (three transplant centers) in India.

MATERIALS AND METHODS

All prospective recipients (and their potential donors) underwent low-resolution HLA typing as well as CDCXM, FCXM and HAS assays. In addition, HAI {single antigen bead assay; (SAB)} was done for all recipients to identify possible anti-HLA antibodies. In a virtual cross-match (VXM), antibody specificity was mapped to donor HLA type to determine donor-specific antibodies (DSA). Only patients without DSA were cleared for the transplant. Alternatively, patients with DSA were offered an exchange in the kidney paired donation (KPD) program. The screening results (CDCXM, FCXM, and HAS) were analyzed, individually as well as in combination of screening assays (CDCXM+HAS, CDCXM+FCXM, and FCXM+HAS) and the results were compared with those from the HAI test.

RESULTS

Out of 100 patients, 69 were males and 31 were females; 85 recipients (85%) underwent a kidney transplant. The sensitivity of CDCXM was only 12.1% and the specificity of CDCXM was 100%; whereas the sensitivity of FCXM was 84.8% and the specificity of FCXM was 89.6%. The sensitivity and specificity of class I HAS was 88.2% and 84.3%, respectively. The sensitivity and specificity class II HAS was 88.0% and 80.0%, respectively. However, when both class I/II HAS were tested together the sensitivity increased to 97.0% and the specificity to 82.1%. Similarly, the sensitivity of combined FCXM+HAS had the sensitivity of 100% and the specificity of 76.1%; CDCXM+FCXM had the sensitivity of 84.8% and the specificity of 89.6% and CDCXM+HAS assays reached 97% with the specificity of 82.1%.

CONCLUSIONS

Our results showed that the algorithm of FCXM with HAS produced the best sensitivity of 100%. The specificity of 76.1% indicate that the combined FCXM+HAS assays may detect up to 24.9% false positive results. We suggest that these false-positives may be easily resolved by performing the virtual crossmatch based on HAI (SAB) results. In our reflex testing algorithmic approach only 49% patients needed HAI (SAB). Finally, our results suggested that the CDCXM assay may be discontinued in pre-transplant workup owing to its very low sensitivity (12.1%).

Nuances of Arteriovenous Fistula Creation for Vascular Access in Hemodialysis

Background With rising incidence and increased life expectancy of patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD), the number of patients requiring hemodialysis has increased substantially. Vascular access is the lifeline for a patient on hemodialysis (HD), and an arteriovenous fistula (AVF) is the undisputed gold standard for HD access. An effective and long-lasting fistula serves to increase the life expectancy of ESRD patients and improves their quality of life.

Learning Objectives This paper aims to give a comprehensive overview of AVF creation, including the various techniques, patient selection, troubleshooting with decision-making, and common complications. Authors share their experience from previous publications and over 2000 AVF surgeries. They have not only described a new modification of the technique of proximal fistula but have also established a direct correlation between bruit and thrill on operation table and success of fistula surgery.

Conclusion A standardized, protocol-driven multidisciplinary approach with careful patient and site selection, guided by outcome predictors, is vital in AVF surgery. Knowledge about the potential complications of AVFs contributes to their timely detection and allows measures to be taken that might prevent deleterious consequences that range from loss of vascular access to serious morbidity and mortality.

Nano architectured cues as sustainable membranes for ultrafiltration in blood hemodialysis

Membranes with zeolites are encouraging for performing blood dialysis because zeolites can eliminate uremic toxins through molecular sieving. Although the addition of various pore-gen and adsorbent in the membrane can certainly impact the membrane production along with creatinine adsorption, however, it is not directed which pore-gen along with zeolite leads to better performance. The research was aimed at reducing the adsorption of protein-bound and uremic toxins by using mordenite zeolite as an adsorbent while polyethylene glycol and cellulose acetate as a pore generating agent. Membranes were cast by a phase-inversion technique which is cheap and easy to handle as compared to the electro-spinning technique. Through this strategy, the ability to adsorb creatinine and solute rejection percentage were measured and compared against the pristine PSU, when only PEG was used as a pore-modifier and when PEG along with CA was used as a pore-modifier along with a different concentration of zeolite. The experiments revealed that PEG membranes can give a better solute rejection percentage (93%) but with a low creatinine adsorption capacity that is 7654 μg/g and low bio-compatibility (PRT 392 s, HR 0.46%). However, PEG/CA membranes give maximum creatinine adsorption that is 9643 μg/g and also better bio-compatibility (PRT 490 s, HR 0.37%) but with a low BSA rejection (72%) as compared to the pristine PSU and PEG membranes. The present study finds that the concentration of mordenite zeolite affects the membrane performance because its entrapment and large pore size of the membrane decreases solute rejection but increases creatinine uptake level along with the better bio-compatibility.

Clinical factors and comorbidities affecting health-related quality of life in postrenal transplant patients

Background:

Health-related quality of life is different among different transplant cohorts with respect to different variables which predict mortality and graft survival. The aim of this study was to identify the effects of clinical factors on the health-related quality of life in postrenal transplant patients.

Methods:

This census study was conducted at the Institute of Kidney Diseases Peshawar, Pakistan. Data were collected on a questionnaire “ Kidney Diseases Quality of Life-Short Form-1.3 Urdu version” and were analyzed in the 3 main domains, for example, physical component summary (PCS), mental component summary, and kidney disease component summary using SPSS version 21. Mean scores for patients with diabetes mellitus (DM), hypertension, levels of hemoglobin, and serum creatinine were compared by unpaired t-test.

Results:

A total of 277 men (87.9%) and 38 (12.1%) women participated in the study. Mean age was 37.26 (±10.14) years (range 18–65 years). Hypertension was reported in 72.2% and DM in 10.8%. Hemoglobin was <12.5g% in 26.0% patients. Patients with DM had significant lower PCS (P = .001) and mental component summary (MCS; P = .001) scores. Patients with hypertension had significant lower MCS score (P = .01). Patients with hemoglobin <12.5g% had significantly lower PCS (P = .001) score than those with hemoglobin >12.5 g%. The PCS score in patients with serum creatinine level >2 mg% was significantly lower (P = .02) than those with serum creatinine <2 mg%.

Conclusion:

Lower graft function and DM were associated with lower PCS and MCS scores. Hypertension was associated with lower MCS score and anemia with lower PCS score.

Outcomes of Endovascular Therapy for Salvage of Hemodialysis Arteriovenous Fistulae

Introduction Arteriovenous fistulae (AVF) for hemodialysis (HD) are prone to development of multiple complications, which can lead to nonfunctioning of the fistula. We report outcomes of endovascular management for dysfunctional HD AVF.

Materials and Methods In this prospective study, patients (43 men, 28 women, mean age 47.4 years) with clinical signs and symptoms of dysfunctional HD AVF and referred to interventional radiology for endovascular management were included. The most common clinical presentation included low flows during hemodialysis (n = 20), absent flow (n = 37), and failure of fistula maturation (n = 14). Patients with central venous obstruction who presented with limb swelling were excluded from this study. Patients underwent venography, venoplasty and thrombectomy, as appropriate, to salvage the fistula. The study outcomes were technical success, hemodynamic success, and clinical success of endovascular therapies in salvaging the fistulae.

Results The technical, hemodynamic and clinical success rates of endovascular therapy for low-flow symptoms were 95%, 70% and 95%, respectively. Among patients who presented with absent flow, endovascular therapy had 81% technical success, 78.3% hemodynamic success, and 81% clinical success. Endovascular therapy was associated with 64.2% technical success, 57.1% hemodynamic success, and 64.2% clinical success in patients presenting with failed maturation of the fistula. The overall clinical success rate was 58/71 (81.7%) and failure rate was 13/71 (18.3%). The overall complication rate of endovascular therapy was 8.4% and the complications included vein rupture in 5 (7%) and balloon rupture in 1 (1.4%).

Conclusion Endovascular therapy for salvage of nonfunctioning hemodialysis AVF is associated with a high-clinical success rate (81.7%) and low-complication rate.

Chronic kidney disease and dialysis therapy: incidence and prevalence in the world

Сhronic kidney disease (CKD) is the important public and medical problem in the world because of a large burden on health care systems. The prevalence of CKD and number of dialysis patients are increasing in the world. The prevalence and incidence of CKD depends on age, race, and gender of patients, region, and the presence of the CKD registry in a country. Diabetes mellitus (DM) and arterial hypertension (AH) are the most common causes of end stage renal disease (ESRD). It is projected that the number of dialysis patients will reach 5.5 million in 2030. Specific strategies and interventions should be urgently aimed at reducing in the burden of CKD by means of the prevention, detection and treatment of DM, AH, and early stages of CKD. One more strategy is the organization of own domestic manufacture of solutions for dialysis therapy.

CRRT in developing world

Continuous renal replacement therapy (CRRT) has become a mainstay therapy in the intensive care unit (ICU) and its utilization continues to increase in developed countries. The wide variations of CRRT practice, however, are evident in developing countries while clinicians in these resource-limited countries encounter various barriers such as a limited number of nephrologists and trained staff, a gap of knowledge, machine unavailability, cultural and socioeconomic aspects, high-cost therapy without reimbursement, and administrative as well as governmental barriers. In this article, we demonstrate the situation of CRRT and discuss the barriers of CRRT in a resource-limited setting. We also discuss the strategies to improve CRRT practice. These recommendations can serve as a fundamental guideline for clinicians to implement CRRT in low-resource settings.

Ethical Challenges in Dialysis and Transplantation: Perspectives From the Developing World

Renal replacement therapies including dialysis and transplantation for patients with end-stage kidney failure are treatment options beyond the reach of a large segment of the population, particularly in resource-constrained settings. Health care professionals practicing within developing countries face unique ethical issues in the provision of these treatment options despite the existence of free treatment at different centers. Apart from issues of accessibility of dialysis services, initiation of treatment can have disastrous consequences for the entire family unit, which is magnified in collectivist societies. Several cost-cutting measures also may have to be used that raise moral dilemmas for physicians. Although transplantation is considered the most cost-effective solution in developing countries, leading to significantly better quality of life, issues of consent from biologically related living donors and the use of marginal donors may place physicians in a quandary. Policy making in developing countries must consider the socioeconomic implications of treatment choices that extend far beyond the treatment cost.

What Role Can the Right to Health Play in Advancing Equity in Kidney Care?

Kidney disease, whether acute or chronic, is an important health concern for more than 750 million people worldwide. Although its magnitude has been better studied within developed countries, evidence increasingly suggests similar scales of impact in developing and underdeveloped countries. On a shared planet where limited resources and high costs keep life-saving care out of reach for the poor and other structurally disadvantaged populations, addressing health concerns on such a large scale requires a governing basis in the recognition of the universal right to health. As designed under international human rights law, the right to health is meant to be legally enforceable on par with other human rights, and so provides a firm guiding framework for advancing health equity. This article traces the evolution of the right to health in international human rights law while assessing the framework's potential contributions to equitable access to treatment in forums including domestic litigation and rights-based advocacy tools. This article ultimately outlines and clarifies the right to health as a viable, justiciable means for advancing equitable access to kidney treatment and care.

Evaluation of safety and efficacy profile of Nigella sativa oil as an add-on therapy, in addition to alpha-keto analogue of essential amino acids in patients with chronic kidney disease

Chronic kidney disease (CKD) encompasses a spectrum of different pathophysio- logic processes associated with abnormal kidney function. When it reaches end-stage renal disease (ESRD), the only option is dialysis and renal transplantation. This is unaffordable by most patients. Hence, newer treatment modalities are being looked for, which can slow down the progression of CKD and delay the development of ESRD. This study aimed to evaluate the efficacy and safety of Nigella sativa oil as an add-on therapy in addition to alpha-keto analogue of essential amino acids in patients with CKD Stages 3 and 4. The study was conducted at a tertiary care center in North India on patients with CKD Stages 3 and 4. It was a prospective, comparative, and open-labeled study. One hundred and fifty patients were enrolled and were randomly divided into two interventional groups. Fourteen patients were lost to follow-up. Group I (control) which had 66 patients received conservative management of CKD consisting of alpha-keto analogue (600 mg tablet three times a day), whereas Group II (test) which had 70 patients received conservative management along with alpha-keto analogue and N. sativa oil (2.5 mL, per orally, once daily) for 12 weeks. Hemogram, renal function, and serum electrolyte tests were done, and adverse events were recorded at baseline and at4, 8, and 12 weeks of treatment. After 12 weeks of treatment, there was a marked improvement in clinical features and biochemical parameters in both the control and test groups. There were a significant reduction in blood urea, serum creatinine, and 24-h total urine protein and a significant improvement in 24-h total urine volume and glomerular filtration rate. N. sativa oil supplementation along with alpha-keto analogue is more more efficacious and safe in delaying the progression of disease patients with CKD Stages 3 and 4.

An Intelligent Iris Based Chronic Kidney Identification System

In recent years, the demand for alternative medical diagnostics of the human kidney or renal is growing, and some of the reasons behind this relate to its non-invasive, early, real-time, and pain-free mechanism. The chronic kidney problem is one of the major kidney problems, which require an early-stage diagnosis. Therefore, in this work, we have proposed and developed an Intelligent Iris-based Chronic Kidney Identification System (ICKIS). The ICKIS takes an image of human iris as input and on the basis of iridology a deep neural network model on a GPU-based supercomputing machine is applied. The deep neural network models are trained while using 2000 subjects that have healthy and chronic kidney problems. While testing the proposed ICKIS on 2000 separate subjects (1000 healthy and 1000 chronic kidney problems), the system achieves iris-based chronic kidney assessment with an accuracy of 96.8%. In the future, we will work to improve our AI algorithm and try data-set cleaning, so that accuracy can be increased by more efficiently learning the features.

Exploring the safety and efficacy of adding ketoconazole to tacrolimus in pediatric renal transplant immunosuppression

BACKGROUND

Guatemala is a developing country in Central America with limited health resources. In order to expand successful renal transplant care to children and adolescents at the lowest possible cost, our pediatric renal transplant clinic uses a post-transplant tacrolimus-sparing strategy via inhibition of CYP3A4.

AIM

To study the safety, efficacy and the associated cost reduction of ketoconazole in combination with tacrolimus in this pediatric population.

METHODS

A retrospective chart review was carried out among the cohort of pediatric renal transplant recipients treated at the Foundation for pediatric renal patients (Fundación para el Niño Enfermo Renal - FUNDANIER), a pediatric tertiary care renal transplant center in Guatemala City, Guatemala. Patient charts were reviewed to ascertain the number of transplant recipients who were transitioned from tacrolimus based immunosuppression to combination therapy with ketoconazole and tacrolimus. Twenty-five post-transplant patients that used ketoconazole combined with tacrolimus were identified. Anthropometric, clinical and laboratory data was collected from patient charts before and after the transition.

RESULTS

Of the 25 patient charts reviewed 12 (48%) patients were male and the average patient age was 13 years. Twenty-four (96%) transplants were from living donors. There was a non-significant difference between the mean tacrolimus doses six months and two months prior to ketoconazole: -0.10 ± 0.04 (95%CI: 0.007, -0.029), P = 0.23. However, the difference between the mean tacrolimus doses six months prior to ketoconazole initiation and six months after ketoconazole addition was significant: 0.06 ± 0.05 (95%CI: -0.034, -0.086) P < 0.001. All tacrolimus doses were reduced by 45% after the addition of ketoconazole. Therapeutic levels of tacrolimus ranged between 6.8-8.8 ng/mL during the study period and patients demonstrated an increase in estimated glomerular filtration rate. The combination of tacrolimus and ketoconazole resulted in a 21% reduction in cost.

CONCLUSION

Patients experienced an effective dose-reduction of tacrolimus with the administration of ketoconazole. There was no relevant variations in tacrolimus serum levels, number of rejections, or significant liver toxicity. The strategy allowed a cost reduction in pediatric immunosuppressive therapy.

The changing patterns of access overtime to the renal replacement therapy programme in Thailand

Based on projected numbers, approximately only 50% of those requiring renal replacement therapy (RRT) receive it. Many patients who require RRT live in low- and middle-income countries. The objective of this study was to examine the changing pattern over time of entry into the RRT programme in Thailand following RRT's inclusion in the Universal Coverage Scheme. This study was an ecological study using the age-period-cohort analysis to look at dialysis registration and kidney transplant trends during RRT programme implementation. Data from 2008 to 2016 of patients diagnosed with end-stage renal disease (ESRD) were obtained from the National Health Security Office. The study found that the numbers of new patients with ESRD, aged 20-69, registered with the dialysis programme increased over time. For patients aged 20-40 years, the dialysis programme took up to 400 new patients for every 1000 new ESRD diagnoses. For kidney transplant, the rates increased slowly. The kidney transplant programme could at best treat only around 50 cases for every 1000 new ESRD diagnoses in patients aged 20-30 years. Findings of this study highlighted the importance of promoting strategies to reduce the increasing number of patients with kidney disease, to consider conservative therapy for older/frail patients, and to improve access to kidney transplantation and live-donation.

Understanding Development of Malnutrition in Hemodialysis Patients: A Narrative Review

Hemodialysis (HD) majorly represents the global treatment option for patients with chronic kidney disease stage 5, and, despite advances in dialysis technology, these patients face a high risk of morbidity and mortality from malnutrition. We aimed to provide a novel view that malnutrition susceptibility in the global HD community is either or both of iatrogenic and of non-iatrogenic origins. This categorization of malnutrition origin clearly describes the role of each factor in contributing to malnutrition. Low dialysis adequacy resulting in uremia and metabolic acidosis and dialysis membranes and techniques, which incur greater amino-acid losses, are identified modifiable iatrogenic factors of malnutrition. Dietary inadequacy as per suboptimal energy and protein intakes due to poor appetite status, low diet quality, high diet monotony index, and/or psychosocial and financial barriers are modifiable non-iatrogenic factors implicated in malnutrition in these patients. These factors should be included in a comprehensive nutritional assessment for malnutrition risk. Leveraging the point of origin of malnutrition in dialysis patients is crucial for healthcare practitioners to enable personalized patient care, as well as determine country-specific malnutrition treatment strategies.

Calcium channel blockers for people with chronic kidney disease requiring dialysis

BACKGROUND

Calcium channel blockers (CCBs) are used to manage hypertension which is highly prevalent among people with chronic kidney disease (CKD). The treatment for hypertension is particularly challenging in people undergoing dialysis.

OBJECTIVES

To assess the benefits and harms of calcium channel blockers in patients with chronic kidney disease requiring dialysis.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies to 27 April 2020 through contact with the Information Specialist using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

All randomised controlled trials (RCTs) and quasi-RCTs that compared any type of CCB with other CCB, different doses of the same CCB, other antihypertensives, control or placebo were included. The minimum study duration was 12 weeks.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study quality and extracted data. Statistical analyses were performed using a random-effects model and results expressed as risk ratio (RR), risk difference (RD) or mean difference (MD) with 95% confidence intervals (CI).

MAIN RESULTS

This review included 13 studies (24 reports) randomising 1459 participants treated with long-term haemodialysis. Nine studies were included in the meta-analysis (622 participants). No studies were performed in children or in those undergoing peritoneal dialysis. Overall, risk of bias was assessed as unclear to high across most domains. Random sequence generation and allocation concealment were at low risk of bias in eight and one studies, respectively. Two studies reported low risk methods for blinding of participants and investigators, and outcome assessment was blinded in 10 studies. Three studies were at low risk of attrition bias, eight studies were at low risk of selective reporting bias, and five studies were at low risk of other potential sources of bias. Overall, the certainty of the evidence was low to very low for all outcomes. No events were reported for cardiovascular death in any of the comparisons. Other side effects were rarely reported and studies were not designed to measure costs. Five studies (451 randomised adults) compared dihydropyridine CCBs to placebo or no treatment. Dihydropyridine CCBs may decrease predialysis systolic (1 study, 39 participants: MD -27.00 mmHg, 95% CI -43.33 to -10.67; low certainty evidence) and diastolic blood pressure level (2 studies, 76 participants; MD -13.56 mmHg, 95% CI -19.65 to -7.48; I² = 0%, low certainty evidence) compared to placebo or no treatment. Dihydropyridine CCBs may make little or no difference to occurrence of intradialytic hypotension (2 studies, 287 participants; RR 0.54, 95% CI 0.25 to 1.15; I² = 0%, low certainty evidence) compared to placebo or no treatment. Other side effects were not reported. Eight studies (1037 randomised adults) compared dihydropyridine CCBs to other antihypertensives. Dihydropyridine CCBs may make little or no difference to predialysis systolic (4 studies, 180 participants: MD 2.44 mmHg, 95% CI -3.74 to 8.62; I² = 0%, low certainty evidence) and diastolic blood pressure (4 studies, 180 participants: MD 1.49 mmHg, 95% CI -2.23 to 5.21; I² = 0%, low certainty evidence) compared to other antihypertensives. There was no evidence of a difference in the occurrence of intradialytic hypotension (1 study, 92 participants: RR 2.88, 95% CI 0.12 to 68.79; very low certainty evidence) between dihydropyridine CCBs to other antihypertensives. Other side effects were not reported. Dihydropyridine CCB may make little or no difference to predialysis systolic (1 study, 40 participants: MD -4 mmHg, 95% CI -11.99 to 3.99; low certainty evidence) and diastolic blood pressure (1 study, 40 participants: MD -3.00 mmHg, 95% CI -7.06 to 1.06; low certainty evidence) compared to non-dihydropyridine CCB. There was no evidence of a difference in other side effects (1 study, 40 participants: RR 0.13, 95% CI 0.01 to 2.36; very low certainty evidence) between dihydropyridine CCB and non-dihydropyridine CCB. Intradialytic hypotension was not reported.

AUTHORS' CONCLUSIONS

The benefits of CCBs over other antihypertensives on predialysis blood pressure levels and intradialytic hypotension among people with CKD who required haemodialysis were uncertain. Effects of CCBs on other side effects and cardiovascular death also remain uncertain. Dihydropyridine CCBs may decrease predialysis systolic and diastolic blood pressure level compared to placebo or no treatment. No studies were identified in children or peritoneal dialysis. Available studies have not been designed to measure the effects on costs. The shortcomings of the studies were that they recruited very few participants, had few events, had very short follow-up periods, some outcomes were not reported, and the reporting of outcomes such as changes in blood pressure was not done uniformly across studies. Well-designed RCTs, conducted in both adults and children with CKD requiring both haemodialysis and peritoneal dialysis, evaluating both dihydropyridine and non-dihydropyridine CCBs against other antihypertensives are required. Future research should be focused on outcomes relevant to patients (including death and cardiovascular disease), blood pressure changes, risk of side effects and healthcare costs to assist decision-making in clinical practice.

The Adverse Effect of COVID Pandemic on the Care of Patients With Kidney Diseases in India

INTRODUCTION

The coronavirus disease 2019 (COVID-19) pandemic has affected the care of patients with noncommunicable diseases, including those suffering from kidney-related ailments. Many parts of the world, including India, adopted lockdown to curb community transmission of disease. The lockdown affected transportation, access to health care facilities, and availability of medicines and consumables as well as outpatient and inpatient services. We aimed to analyze the effect of lockdown imposed due to the COVID-19 pandemic on the care of patients with kidney diseases in India.

METHODS

We surveyed 19 major hospitals (8 in the public and 11 in the private sector) to determine the effect of lockdown on the care of patients with kidney disease, including those on dialysis after the first 3 weeks of lockdown.

RESULTS

The total number of dialysis patients in these centers came down from 2517 to 2404. Approximately 710 (28.2%) patients missed 1 or more dialysis sessions, 69 (2.74%) required emergency dialysis sessions, 104 (4.13%) stopped reporting for dialysis, and 9 (0.36%) were confirmed to have died. Outpatient attendance in the surveyed hospital came down by 92.3%, and inpatient service reduced by 61%. Tele-consultation was started but was accessed by only a small number of patients.

CONCLUSION

Lack of preparedness before lockdown resulted in an interruption in health care services and posed an immediate adverse effect on the outcome of dialysis patients and patients with kidney disease in India. The long-term impact on the health of patients with less severe forms of kidney disease remains unknown.

Diagnostic Challenges of Acute Kidney Injury in Asia

Early diagnosis of acute kidney injury (AKI) is an important step to improve AKI outcome. In Asia, several distinct conditions of this region such as environment (tropical climate), socioeconomic status (high-resource and low-resource settings), process of care (shortage of nephrologists), exposure factors (specific tropical infections such as leptospirosis, malaria, dengue), and inherent factor (aging) make the diagnosis of AKI in Asia more challenging than in other parts of the world. To improve the diagnosis of AKI, novel tools such as clinical risk scores, AKI alert systems, and telemedicine should be implemented into current clinical practice.

Peritoneal Dialysis Use and Practice Patterns: An International Survey Study

RATIONALE & OBJECTIVE

Approximately 11% of people with kidney failure worldwide are treated with peritoneal dialysis (PD). This study examined PD use and practice patterns across the globe.

STUDY DESIGN

A cross-sectional survey.

SETTING & PARTICIPANTS

Stakeholders including clinicians, policy makers, and patient representatives in 182 countries convened by the International Society of Nephrology between July and September 2018.

OUTCOMES

PD use, availability, accessibility, affordability, delivery, and reporting of quality outcome measures.

ANALYTICAL APPROACH

Descriptive statistics.

RESULTS

Responses were received from 88% (n=160) of countries and there were 313 participants (257 nephrologists [82%], 22 non-nephrologist physicians [7%], 6 other health professionals [2%], 17 administrators/policy makers/civil servants [5%], and 11 others [4%]). 85% (n=156) of countries responded to questions about PD. Median PD use was 38.1 per million population. PD was not available in 30 of the 156 (19%) countries responding to PD-related questions, particularly in countries in Africa (20/41) and low-income countries (15/22). In 69% of countries, PD was the initial dialysis modality for≤10% of patients with newly diagnosed kidney failure. Patients receiving PD were expected to pay 1% to 25% of treatment costs, and higher (>75%) copayments (out-of-pocket expenses incurred by patients) were more common in South Asia and low-income countries. Average exchange volumes were adequate (defined as 3-4 exchanges per day or the equivalent for automated PD) in 72% of countries. PD quality outcome monitoring and reporting were variable. Most countries did not measure patient-reported PD outcomes.

LIMITATIONS

Low responses from policy makers; limited ability to provide more in-depth explanations underpinning outcomes from each country due to lack of granular data; lack of objective data.

CONCLUSIONS

Large inter- and intraregional disparities exist in PD availability, accessibility, affordability, delivery, and reporting of quality outcome measures around the world, with the greatest gaps observed in Africa and South Asia.

Hemodialysis at Doorstep - "Hub-and-Spoke" Model of Dialysis in a Developing Country

End-stage kidney disease has become a huge burden in our country. There has been an increase in dialysis centers across the country. State-funded dialysis has been initiated in many states of India. However, most of the centers are concentrated in the cities. Patients living in the peripheral districts have to travel long distance to reach the dialysis centers. In addition, there is a dearth of nephrology services in the peripheral areas. To address this problem, the hub-and- spoke model of dialysis has been initiated in Telangana state in South India, which has brought dialysis at the doorstep for people residing in remote districts. This study highlights the important features of this model.

The Value of Renal Biopsy in Non-Insulin-Dependent Diabetes Mellitus in Singapore over the Past Two Decades

Objective

This study on the prevalence of diabetic nephropathy (DN) and coexistence of non-diabetic renal disease (NDRD) in a cohort of 255 non-insulin-dependent diabetes mellitus (NIDDM) patients aims to determine the value of performing renal biopsies in these patients and elucidate the factors which could affect their progression to end-stage renal disease (ESRD).

Methods

Among 255 NIDDM patients, 93 had DN alone, 69 had NDRD alone, and the remaining 93 had DN plus NDRD (mixed group). The indications for renal biopsy were based on clinical suspicion of superimposed NDRD, including heavy or rapidly increasing proteinuria, renal impairment even though diabetes is of relatively short duration, rapidly declining renal function, and presence of hematuria with dysmorphic red blood cells suggesting presence of glomerulonephritis.

Results

The following were predictors of ESRD: high systolic BP at biopsy, longer duration of diabetes, heavy proteinuria, and presence of diabetic retinopathy. Comparing patients in the NDRD group with the DN group and the mixed group, the NDRD group had lower serum creatinine and higher eGFR with lower urinary proteinuria and higher serum albumin at presentation and on follow-up. Kimmelstiel-Wilson nodules were associated with a poorer prognosis leading to a higher occurrence of ESRD among patients with DN.

Conclusion

Renal biopsy is of value in indicating the prognosis of NIDDM patients with DN based on the diabetic lesions. For NIDDM patients with atypical course and suspicion of associated NDRD, a renal biopsy would enable us to diagnose the underlying NDRD and offer appropriate therapy. Most nephrologists would consider renal biopsy for an NIDDM patient based on clinical indications like atypical clinical course and suspicion of an associated NDRD, but they would not perform a routine renal biopsy like for a CKD patient, unless it is for a research indication.

Deceleration of Disease Progress Through Ayurvedic Treatment in Nondialysis Stages IV-V Patients with Chronic Renal Failure: A Quasi-Experimental Clinical Pilot Study with One Group Pre- and Postdesign and Two Premeasurements

Objective: The aim of this study was to evaluate the effects of Ayurvedic treatment on deceleration of the disease progress of nondialysis patients with stage IV or V chronic renal failure (CRF). Materials and Methods: A complex oral and proctocolonic Ayurvedic multiherbal medication was administered daily for 1 month to inpatients. Thereafter, patients were treated as outpatients with oral medication for additional 5 months. Four renal function tests (RFTs) were evaluated at various time points (TPs): (1) 6 months before baseline (TP -6), (2) at baseline (TP 0), and (3) after completion of 6 months of treatment (TP +6). Repeated-measures analysis of variance (ANOVA) with Greenhouse-Geisser correction and Friedman's ANOVA by ranks were used to analyze the RFTs. For post hoc tests, the Bonferroni correction was applied. Bias-corrected effect sizes (Hedges) for the treatment were calculated. Results: Sixty-four nondialysis CRF patients with laboratory investigations of the preceding 6 months were included; 12 patients discontinued the treatment. Fifty-two patients with stage IV or V at baseline completed the study. Mean concentrations of estimated glomerular filtration rate (eGFR), serum creatinine, and hemoglobin differed significantly between TPs (eGFR: F = 15.3, p < 0.001; serum creatinine: F = 29.3, p < 0.001; blood urea: F = 2.0, p = 0.159; hemoglobin: F = 53.9, p < 0.001). Pairwise comparisons of the mean differences between TPs are significant for eGFR, creatinine, and hemoglobin. For blood urea, a significant decrease was observed for the treatment period [15.9(↓) mg/dL, standard error 4.0; n = 52], but a nonsignificant increase was observed for the pretreatment period [16.2(↑) mg/dL, standard error 9.8] due to insufficient data for TP -6 (n = 26). The effect sizes for eGFR, creatinine, blood urea, and hemoglobin were medium (0.45, 0.53, 0.44, and 0.30). Conclusions: After 6 months of treatment, statistically and clinically significant improvements of eGFR, creatinine, blood urea, and hemoglobin and a significant shift to better CRF stages were observed. Several cardinal symptoms were also significantly reduced. Randomized controlled trials are warranted to evaluate the effects in comparison to usual care.

Effectiveness of pharmacist intervention model for chronic kidney disease patients; a prospective comparative study

Background Chronic Kidney Disease (CKD) is a global health concern with profound risk of cardiovascular disease, end stage renal failure and early mortality. Pharmacists' interventions during chronic disease management have been promising. However, evidence of pharmacist`s involvement in chronic kidney dosease is limited, particularly in developing countries. Objective To implement and evaluate the impact of pharmacist led intervention among pre-dialysis CKD patients. Setting Nephrology outpatient department of tertiary healthcare hospital. Methods Patients with chronic kidney disease from stage 2 to 4 attending hospital between October to December 2018 were enrolled in a multi-arm pre-post prospective study. Pharmacist interventional model consisted of disease education, dietary recommendations, counseling to improve medication adherence along with telephonic follow-up. Interventional group received pharmacist interventional model; whereas control group only received the usual care. The impact of pharmacist`s involvements were evaluated by observing the improvements in knowledge and adherence scores, physiological profile and body composition analysis assessed by body composition monitor (BF-508^®) at the end of follow-up of 3 months. Both intervention and control groups were compared by appropriate statistical techniques. Main outcome measure Knowledge and adherence scores, physiological profile and body composition analysis Results Total 120 patients (60 in each group) completed the study. Baseline variables were comparable between the two groups. Pharmacist interventional model causes significant improvement in knowledge score upon follow up between intervention and control groups (19.10 ± 3.65 versus 17.57 ± 3.55, p = 0.022). Likewise, Medication adherence score of intervention group significantly improved as compared to control group (p < 0.05) following the implementation of pharmacist intervention model. Physiological analysis showed small improvements in the intervention group but were not significant. Body composition analysis revealed higher body and visceral fat in both groups at the end of follow up. Conclusion Our analysis underscored that the tested pharmacist interventional model is an effective tool in improving disease knowledge and medication adherence among patients with chronic kideney disease.

Access to CKD Care in Rural Communities of India: a qualitative study exploring the barriers and potential facilitators

Background

Despite the high and rising burden of chronic kidney disease (CKD) in South Asia, factors that influence access to CKD care at the community level have not been studied previously, especially in the rural areas. We conducted a mixed methods study and interviewed key stakeholders to explore the views and experiences of key stakeholders, and identify barriers and potential facilitators that influence access to CKD care at the primary care level in rural India.

Methods

A total of 21 stakeholders participated in the study. We conducted 15 in-depth interviews on a purposive sample of stakeholders (CKD patients, healthcare providers and health planners) and one focus group discussion with 6 community health workers. The interviews were audio-recorded and transcribed verbatim. We employed the Lévesque’s framework for access to care to base interview guides and structure the initial codes. By inductive and deductive approaches, thematic analysis was undertaken using QSR NVivo version 11.

Results

The major patient-level barriers to CKD care as reported by the most patients and healthcare providers was poor knowledge and awareness of CKD. Health system-level barriers included shortages of skilled healthcare professionals and medicines, fragmented referrals pathways to the specialists at the hospitals with inadequate follow up care. Many patients and healthcare providers, when asked about areas for improving access to CKD care, reported educational initiatives to increase awareness of CKD among healthcare providers and patients, provision of CKD related supplies, and a systems-level approach to care coordination including task shifting by engaging community health workers in CKD care, as potential facilitators.

Conclusions

We identified several barriers to access CKD care at the primary care level in rural India that need urgent attention. Targeted CKD screening programs and CKD specific educational initiatives may improve awareness of CKD. Additionally, primary care infrastructure needs to be strengthened for CKD care, ensuring trained staff, availability of essential diagnostics and medications, and creating efficient referral pathways for quality CKD care.

Prevalence of Chronic Kidney Disease in Cuttack District of Odisha, India

Chronic kidney disease is one of the major health challenges in India. Cuttack district of the Odisha state of India is regarded as a hotspot for chronic kidney disease (CKD). However, there is limited information on true prevalence. This study estimates the prevalence of CKD in the Narsinghpur block of Cuttack district, Odisha. A cross-sectional study was conducted among population members aged 20-60 years. Using a multi-stage cluster sampling. 24 villages were randomly selected for mass screening for CKD. Blood samples were collected and glomerulus filtration rates were calculated. It was found that among the 2978 people screened, 14.3% were diagnosed with CKD and 10.8% were diagnosed with CKD without either diabetes or hypertension. In one-third of the sampled villages, about 20% population was diagnosed with CKD. The prevalence was higher among males (57%), in the population below 50 years of age (54%), lower socioeconomic groups (70%), and agricultural occupational groups (48%). Groundwater tube wells (49%) and wells (41%) were the main drinking water sources for CKD patients. This study highlights the need for detection of unknown etiologies of CKD and public health interventions for the prevention of CKD in India.

Cadaveric renal transplantation: Our experience at a tertiary care centre in India

BACKGROUND

Renal transplantation in developing countries like India is largely live donor transplantation. Cadaveric transplantation comprises <2% of all transplants in India.

METHODS

Ninety-two cadaveric renal transplantations were included. Various donor and recipient characteristics were analysed along with graft and patient survival, using Kaplan-Meier method.

RESULTS

The mean age of the recipients was 35.5 ± 10.9 years while that of cadaver was 43.9 ± 17.0 years. Proportion of females among recipients was 47.8% while that of donors was 34.8%. The most common underlying pathology was chronic glomerulonephritis (44.6%). Antithymocyte globulin was used as induction in 84.8% of cases. Tacrolimus-based triple-drug regimen was most commonly used as maintenance (80.4%). The mean follow-up time was 39.02 ± 28.24 months. The most common cause of death was sepsis (47%). More than 50% deaths (9/17) occurred within first 3 years, while 61.5% of graft loss occurred 5 years after transplantation. The mean graft survival time was 81.6 months (95% confidence interval [CI]: 72.8-90.4). Cumulative proportion of graft survival was 91.6% at 3 years and 77.1% at 5 years. Although females have better mean graft survival time (91.6 vs 73.5 months), it was not a significant difference as shown by log-rank test (p value = 0.062). Pretransplant haemodialysis has no significant effect on graft loss, but patients on peritoneal dialysis have significantly higher odds of graft loss (odds: 4.86, p value < 0.05 [0.018]). The mean patient survival time was 99.5 months (95% CI: 84.0-114.9). Cumulative proportion of patient survival was 83.3% at 3 years and 70.8% at 5 years.

CONCLUSION

Graft and patient survival rate of cadaveric transplant at our centre was satisfactory. There is need to sensitise and augment the rate of cadaveric transplantation to increase the donor pool.

Assess the Illness Perception and Treatment Adherence among Patients with End-Stage Renal Disease

Background:

Chronic Renal Disease (CRD) complications had a sizeable effect on the patients. This study evaluates illness perception, treatment adherence and clinical outcomes of patients with End-Stage Renal Disease (ESRD) and finds an association with variables.

Materials and Methods:

A descriptive cross-sectional study was conducted among patients at Sri Ramachandra Institute of Higher Education and Research, Chennai, India during October and November 2017. Data were collected through interviews of each patient separately before hemodialysis. Demographic, clinical variables, identity dimension and control dimension of patients were assessed. Adherence behaviours were measured using ESRD-AQ in four dimensions. Clinical outcome was evaluated based on biochemical parameters. The collected data were analysed by percentage distribution and regression analysis.

Results:

The study had 120 patients with ESRD with male to female ratio of 2:1 where the majority (35.80%) were in the age group of 51–60. The identity dimension mean (SD) score was 10.80 (1.51). Under the control dimension mean scores were higher in the sub-dimension of emotional representations, consequences and personal control. Among 120 patients, 63 (52.50%) had adherence to dietary restriction. A statistically significant association was observed between timeline with Body Mass Index (BMI) (F₃ = 4.81, p = 0.003) and comorbidity (F₂ = 2.99, p = 0.022).

Conclusions:

The higher mean score in the sub-dimensions of emotional representations indicates a higher degree of emotional distress due to low adherence to prescribed medications.

A Global Evolutionary Trend of the Frequency of Primary Glomerulonephritis over the Past Four Decades

Objective

The pattern of glomerulonephritis (GN) in Singapore is compared with that of 19 other countries to review changing trends in the evolution of GN in Asian, Eastern, and Western countries.

Method

Three thousand two hundred and eighty-nine renal biopsies in Singapore were reviewed and compared with that of 19 other countries.

Results

IgA nephritis is on the decline in many countries, including Singapore, though it still remains the commonest GN in Singapore. Membranous GN that if used to be more frequently present in Western countries has also declined though it continues a rising trend in countries such as Singapore and China. Worldwide, the frequency of focal sclerosing glomerulosclerosis (FSGS) continues to increase in many countries, but in some countries, the frequency is still low with mesangiocapillary GN remaining indigenous.

Conclusion

Urbanization and socioeconomic changes and less exposure to parasitic and other infestations have transformed Singapore's pattern, which is tending toward that of more developed countries. Antigenic exposure due to lifestyle changes, environmental, and industrial pollution are significant contributory factors that affect the evolutionary trend of GN in many countries. The rising trend in the frequency of FSGS may reflect aging and obesity.

Environmental impact on the onset of hypertension-induced end-stage renal disease

This study intends to assess the impact of environmental factors on the onset of hypertension-induced end-stage renal disease (ESRD) and to compare the level of oxidative stress with nonhypertensive diabetic ESRD. ESRD patients were evaluated along with healthy controls through questionnaire for demographic, nutritional and lifestyle variables. Oxidants were measured along with antioxidants. Multiple linear regression (MLR) models were applied to analyze association of studied variables with oxidants and antioxidants. Most of the hypertensive nephrosclerotic patients were residing in locality that was either closer to industrial belt or polluting water bodies, belonging to low socioeconomic status that invariably affected their lifestyle and nutritional status. Hypertensive ESRD patients showed more pronounced oxidative stress than diabetic ESRD. Several of the studied variables were significantly associated with oxidants and antioxidants. Demographic, nutritional and lifestyle variables appeared to have suggestive effect on the onset of hypertensive nephrosclerosis.
