Purpose: Hyperkalemia is a common metabolic complication of chronic kidney disease (CKD) and is associated with several serious adverse events. We aimed to treat/prevent hyperkalemia using the new of potassium-binders, allowing maintained renin-angiotensin-aldosterone system inhibitors (RAASi) treatment in proteinuric CKD and/or congestive heart failure (CHF) patients.

Patients and methods: We conducted a retrospective cohort study in long-term users of potassium binders for chronic hyperkalemia. Patients aged 18 years and older, treated with potassium-binders and who met the reimbursement criteria and indication for RAASi treatment were included.

Results: Fifty-seven percent of the patients were males and mean age was 65 years. During the study period, no patients were admitted to hospital due to hyperkalemia after initiation of potassium binders. Potassium maximum values were significantly lower after treatment. Few patients reported major side effects, and discontinuation was mostly due to normokalemia. We found no significant changes in bicarbonate, serum creatinine or GFR stage after starting potassium binder treatment. All patients on RAASi treatment before initiating potassium-binders were retained on RAASi treatment.

Conclusion: New potassium binders in clinical practice are an easy and safe treatment with few side effects and good tolerance, that significantly lowers the risk of hyperkalemia. Furthermore, and most importantly, patients can be maintained on RAASi treatment.

Purpose: The present study aimed at evaluating the survival rate, its associated factors, and the causes of death in elderly patients undergoing continuous ambulatory peritoneal dialysis (CAPD) in Vietnam.

Patients and methods: This is a retrospective, observational study conducted among patients aged ≥65 years who underwent CAPD at Thong Nhat Hospital, Ho Chi Minh City, Vietnam, from April 2012 to December 2020. The Kaplan-Meier method was used to calculate the cumulative survival rate, and the Log rank test was used to analyze the factors associated with the survival rate of patients.

Results: This study enrolled a total of 68 patients with a mean age of 71.93 ± 7.44 years at the initiation of CAPD. The most common complication among kidney failure patients was diabetic nephropathy (39.71%). The rate of concomitant cardiovascular diseases was 58.82%. The average survival rate was 45.59 ± 4.01 months. Peritonitis was the most common factor causing death (31.25%), followed by cardiovascular diseases (28.12%) and malnutrition (25%). The factors that impacted the survival rate included concomitant cardiovascular diseases, low serum albumin (<35 g/dL), and an indication of CAPD due to exhausted vascular access for hemodialysis at baseline. The main factor associated with a shorter survival time was concomitant cardiovascular diseases.

Conclusion: It is necessary to improve the survival time beyond 5 years for elderly patients undergoing CAPD, especially for those with concomitant cardiovascular diseases. Besides the prevention of peritonitis, adequate measures to protect from cardiovascular diseases and malnutrition will reduce the mortality rate in patients on CAPD.

Background: Anemia is prevalent among patients with chronic kidney disease (CKD), yet current evidence indicates that treatment may not adhere to Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. We aimed to document the management of patients with non-dialysis-dependent (NDD)-CKD receiving erythropoiesis-stimulating agent (ESA) therapy in Europe.

Methods: This retrospective, observational study extracted information from medical records in Germany, Spain, and the UK. Eligible patients were adults with NDD-CKD stages 3b-5 who initiated ESA therapy for anemia between January and December 2015. Anemia was defined as hemoglobin (Hb) <13.0 g/dL (males) or <12.0 g/dL (females). Data regarding ESA treatment, treatment response, concomitant iron therapy and blood transfusions were extracted up to 24 months post-ESA initiation, and data on CKD progression until abstraction date.

Results: Eight hundred and forty-eight medical records were abstracted. Approximately 40% received no iron therapy prior to ESA initiation. At ESA initiation, mean ± standard deviation Hb level was 9.8 ± 1.0 g/dL. Most patients received darbepoetin alfa, and switching between ESAs was rare (8.5% of patients). Concomitant intravenous and oral iron therapy was prescribed for 36% and 42% of patients, respectively, during initial ESA therapy. Mean Hb levels reached the target level (10-12 g/dL) within 3-6 months of ESA initiation. Hb, transferrin saturation, and ferritin levels were infrequently monitored from 3 months post-ESA initiation. Rates of blood transfusion, dialysis, and diagnosis of end-stage renal disease were 16.4%, 19.3%, and 24.6%, respectively. Rates of kidney transplant and death were 4.8% and 8.8%, respectively.

Conclusion: Among ESA-treated patients, ESA initiation was in accordance with KDIGO guidelines, but subsequent monitoring of Hb and iron deficiency were suboptimal.

Chronic kidney disease (CKD) is associated with significant morbidity and mortality worldwide. In recent years, our understanding of genetic causes of CKD has expanded significantly with several renal conditions having been identified. This review discusses the current landscape of genetic kidney disease and their potential treatment options. This review will focus on cystic kidney disease, glomerular disease with genetic associations, congenital anomalies of kidneys and urinary tract (CAKUT), autosomal dominant-tubulointerstitial kidney disease (ADTKD), inherited nephrolithiasis and nephrocalcinosis.

Background: Diabetes mellitus and hypertension are the most prominent conditions causing chronic kidney disease and eventually end-stage renal disease. Renal replacement therapy, particularly hemodialysis (HD), is the mainstay of treatment. The aim of this study is to assess the overall survival status of HD patients and potential survival predictors at Saint Paul hospital millennium medical college (SPHMMC) and Myungsung Christian Medical Center (MCM) in Addis Ababa, Ethiopia.

Methods: A retrospective cohort study was conducted on HD patients at SPHMMC and MCM general hospital from January 1, 2013 to December 30, 2020. Kaplan Meier, Log-rank, and Cox proportional regression models were used for the analysis. Estimated risks were reported as hazard ratios with 95% confidence intervals and P<0.05 was considered as having a significant association.

Results: A total of 128 patients were included in the study. Median survival time was 65 months. The predominant co-morbid condition was found to be diabetes mellitus with hypertension (42%). The total risk time for these patients was 143,617 person years. The overall incidence rate of death was 2.9 per 10,000 person years (95% CI=2.2-4). Patients who developed blood stream infection were 2.98-times more likely to die than those without infection. Those using an arteriovenous fistula were 66% less likely to die than those using a central venous catheter. Additionally, patients treated in a government-owned facility were 79% less likely to die.

Conclusion: The study identified that the median survival time of 65 months was comparable with developed nations. Significant predictors of death were found to be blood stream infection and type of vascular access. Government-owned treatment facilities showed better patient survival.

Background: Percutaneous kidney biopsy (PKB) is the gold standard for diagnosing various kidney diseases, but it can result in potential complications. This study aimed to compare kidney tissue adequacy and safety between the two biopsy techniques, including cranial direction (CN) and caudal direction (CD), of needle biopsy under real-time ultrasonogram guidance.

Methods: This single-center, prospective, single-blinded, randomized trial included patients undergoing native PKB from July 5, 2017, to June 30, 2019. Patients were randomized to the CN and CD groups. Adequacy and complications between the two groups were analyzed. All PKBs were performed under real-time ultrasonogram guidance with a 16-gauge kidney biopsy needle.

Results: A total of 107 participants were enrolled (53 in the CD group and 54 in the CN group). The CD group has more glomeruli than the CN group but with no statistical significance (16 versus 11, p = 0.0865). The CD group obtained more adequate kidney tissue samples than the CN group (69.8% versus 59.3%, p = 0.348). The number of inadequate glomeruli tissue sampling is similar in both groups (14 versus 15, respectively). Furthermore, the CN group had more adverse events, including Hb decline ≥10% after kidney biopsy, perinephric hematoma size ≥1 cm, hematuria, and the need for blood transfusion, than the CD group.

Conclusion: The CD technique of the percutaneous kidney biopsy in the native kidney has fewer complications and was possibly more effective than the CN technique.

The burden of chronic kidney disease (CKD) and other comorbidities, such as hypertension and diabetes, which increase the risk of developing CKD, is on the rise in the Middle East and Africa. The Middle East and Africa CKD (MEA-CKD) steering committee, comprising eminent healthcare specialists from the Middle East and Africa, was formed to identify and propose steps to address the gaps in the management of CKD in these regions. The current article lists the MEA-CKD steering committee meeting outcomes and evaluates the available evidence supporting the role of novel therapeutic options for patients with CKD. The need of the hour is to address the gaps in awareness and screening, early diagnosis, along with referral and management of patients at risk. Measures to bring about appropriate changes in healthcare policies to ensure access to all benefit-proven protective therapies, including novel ones, at community levels are also vital for reducing the overall burden of CKD on the healthcare system as well as governing bodies, especially in developing countries of the Middle East and Africa.
