Improving self-dependency in Pakistan: Experience of a locally prepared automated PD machine.

The increasing burden of haemodialysis on healthcare systems merits efforts to make peritoneal dialysis (PD) more accessible to the population in need of kidney replacement therapy. Automated PD (APD) may be a suitable alternative to continuous ambulatory peritoneal dialysis for home dialysis especially for children, elderly and patients who lead a busy schedule in their jobs thus leaving more time for personal and family activities during the day. Recently, a local bioengineering company took the initiative to develop a locally manufactured, low-cost APD cycler in Pakistan, with an aim to improve the self-dependency and home-based kidney replacement therapy. We herein present our first experience of APD on this locally manufactured APD cycler. It was an investigator-led study on the utility of a locally manufactured APD cycler and the safety and efficacy of the standard operating procedures developed and adopted by the study authors. A total of eight patients agreed to participate in this study extending from September 2021 to August 2022. There were four male and four female patients, and the mean age was 52.5 + 19.71 years. The locally manufactured cycler provided more than 1600 h of APD sessions. The APD sessions were well tolerated with only a few instances of minor mechanical and software issues that did not require termination of therapy. There were no episodes of peritonitis; however, one of the patients had an episode of exit site and tunnel infection that did not seem to be related to the procedure. Our experience with locally manufactured APD cycler was successful and without major adverse events. We believe the locally produced APD cycler is a viable cost-effective option for patients requiring PD and may herald a new era of self-dependency for patients considering or undergoing PD in Pakistan.

Capacity for the management of kidney failure in the International Society of Nephrology South Asia region: report from the 2023 ISN Global Kidney Health Atlas (ISN-GKHA).

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

Association of Anemia with Parathyroid Hormone Levels and Other Factors in Patients with End-Stage Renal Disease Undergoing Hemodialysis: A Cross-Sectional, Real-World Data Study in Pakistan.

End-stage renal disease (ESRD) patients are mostly managed with maintenance hemodialysis (MHD). ESRD patients on MHD also present with many complications, such as anemia, hyperparathyroidism, and hepatitis prevalence. This study depicts the real-world scenario of anemia among MHD and end-stage renal disease patients in the Pakistani population. A retrospective, multicentric, and real-world data analytical study was conducted at 4 dialysis centers in Pakistan. The study had a sample size of n = 342 patients on maintenance hemodialysis. The data were gathered from the medical records of patients. Data analysis was performed using STATA Version 16. Statistical significance was gauged at a 0.05 level of significance. According to our results, the mean age of the patients was 45 (±15) years. Most of the patients were male (n = 234, 68.4%), whereas 58.1% of the patients were maintained on twice-weekly hemodialysis. The most commonly reported comorbidities were hypertension and diabetes mellitus. The frequency of dialysis (P < 0.01) and comorbidities (P = 0.009) had a significant association with anemia in MHD patients. The majority of the patients had hyperparathyroidism (52%) with anemia. Upon performing binary logistic regression, multivariate analysis displayed a similar odds value for having anemia in patients with every additional month in the duration of hemodialysis (OR 1.01, P = 0.001), the odds of anemic patients having a positive antihepatitis-C antibody (OR 2.22, P = 0.013), and the odds of having anemia in patients in the age category below 45 years (OR 1.93, P = 0.013). In conclusion, the study results depict that every additional month in the duration of hemodialysis, age (<45 years), and positive anti-HCV antibody status, these variables were more likely to have anemia in our study MHD patients. While in our final multivariate model, no statistically significant association was observed between hyperparathyroidism and anemia.

Overcoming barriers and building a strong peritoneal dialysis programme - Experience from three South Asian countries.

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

Comparison of Efficacy of Dexamethasone and Methylprednisolone in Improving PaO2/FiO2 Ratio Among COVID-19 Patients.

Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the reason for the global pandemic that started from Wuhan, China, in December 2019, known as coronavirus diseases 2019 (COVID-19). Acute respiratory distress syndrome happened in COVID-19 not just because of uncontrolled viral replication but also because of an uncontrolled immune reaction from the host. That's why antiviral and anti-inflammatory treatments have become an increasing concern for clinicians. Methods A retrospective quasi-experimental study design was used to assess the effectiveness of methylprednisolone and dexamethasone in the improvement of PaO2/FiO2 (P/F) ratio in COVID-19 patients. We included 60 participants for this study by using a convenient sampling technique and divided them into two groups with 30 patients in each group. Group 1 was given dexamethasone 8 mg twice daily, and group 1 given methylprednisolone 40 mg twice daily for eight days. We recorded C-reactive protein (CRP), serum ferritin level, and P/F ratio before administration of both drugs and after administration of drugs for eight days. We used the paired t-test to assess the effect of both drugs on the P/F ratio of participants. Results The initial mean CRP in group 1 was 110.34, which reduced to 19.45 after administration of dexamethasone; similarly, the CRP in group 2 was 108.65, which reduced to 43.82 after administering methylprednisolone for eight days. In P/F ratio improvement, the calculated significance value for dexamethasone (p=0.000) was less than the table value at 0.05 in all sections, p-value for methylprednisolone (p=0.009) was also less than the table value at 0.05, which shows that both dexamethasone and methylprednisolone were effective in improving P/F ratio. Calculated p-value for dexamethasone (p=0.000) was lower than the calculated p-value for methylprednisolone (p=0.009), which shows that dexamethasone is more effective as compare to methylprednisolone. Conclusions Steroid therapy is effective in controlling inflammation markers, and especially dexamethasone is significantly effective in improving the P/F ratio in COVID-19 patients.

Use of Continuous Glucose Monitoring in Patients with Diabetes Mellitus on Peritoneal Dialysis: Correlation with Glycated Hemoglobin and Detection of High Incidence of Unaware Hypoglycemia.

INTRODUCTION: Glycated hemoglobin is used to assess diabetic control although its accuracy in dialysis has been questioned. How does it compare to the Continuous Glucose Monitoring System (CGMS) in peritoneal dialysis (PD) patients? METHODS: We conducted a retrospective analysis of 60 insulin-treated diabetic patients on PD. We determined the mean interstitial glucose concentration and the proportion of patients with hypoglycemia (<4 mmol/l) or hyperglycemia (>11 mmol/l). RESULTS: The correlation between HbA1c and glucose was 0.48, p < 0.0001. Three of 15 patients with HbA1c >75 mmol/mol experienced significant hypoglycemia (14-144 min per day). The patients with frequent episodes of hypoglycemia could not be differentiated from those with frequent hyperglycemia by demographics or PD prescription. CONCLUSION: HbA1c and average glucose levels measured by the CGMS are only weakly correlated. On its own, HbA1c as an indicator of glycemic control in patients with diabetes on PD appears inadequate. We suggest that the CGMS technology should be more widely adopted.

Increasing the use of biocompatible, glucose-free peritoneal dialysis solutions.

A major concern inhibiting some clinicians from embracing peritoneal dialysis (PD) as the preferred first modality of dialysis is the effects of PD solutions on the peritoneal membrane. These anatomical and functional changes predispose to complications like peritonitis, encapsulating peritoneal sclerosis and ultrafiltration failure. In recent years, "biocompatible" and glucose-sparing PD regimens have been developed to minimize damage to the peritoneal membrane. Can the use of these more expensive solutions be justified on current evidence? In this review of the literature, we explore how we may individualize the prescription of biocompatible PD fluid.
