Epoetin alfa resistance in hemodialysis patients with chronic kidney disease: a longitudinal study.

This study aimed to investigate the factors associated with resistance to recombinant human erythropoietin therapy with epoetin alfa (αEPO). We performed a prospective, longitudinal study of hemodialysis patients receiving treatment with αEPO at our reference hospital from July 2015 to June 2016. Clinical data was collected, and the response to αEPO treatment was evaluated using the erythropoietin resistance index (ERI). The ERI was defined as the weekly weight-adjusted αEPO dose (U/kg per week)/hemoglobin level (g/dL). A longitudinal linear regression model was fitted with random effects to verify the relationships between clinical and laboratory data and ERI. We enrolled 99 patients (average age, 45.7 (±17.6) years; male, 51.5%; 86.8% with hypertension). The ERI showed a significant positive association with serum ferritin and C-reactive protein, percentage interdialytic weight gain, and continuous usage of angiotensin receptor blocker (ARB) hypertension medication. The ERI was negatively associated with serum iron and albumin, age, urea reduction ratio, and body mass index. Our findings indicate that resistance to αEPO was related to a low serum iron reserve, an inflammatory state, poor nutritional status, and continuous usage of ARBs.

It has prevalence estimates of 30%–50% and is an independent predictor of increased mortality in CKD patients. The aim of this study is to analyze the prevalence of PH in patients with CKD, its severity in different stages of CKD, and risk factors for it. One hundred and eight patients with CKD treated at Karnataka Institute of Medical Sciences, Hubli, Karnataka,...

Abstract To determine the prevalence of cardiovascular comorbidities and their active risk factors in the selected hemodialysis centers in the Gulf Cooperation Council (GCC) countries, the Dialysis Outcome and Practice Pattern Study (DOPPS) was performed on 40 dialysis centers in the six GCC countries from June 2012 to May 2015. There were 21 dialysis centers from Saudi Arabia, nine from the United Arab Emirates (UAE), four from Kuwait, four from Oman, two from Qatar, and one from Bahrain. There were 922 patients participating in the study; 419 patients from Saudi Arabia, 144 from the UAE, 164 from Kuwait, 89 from...

Abstract Dyspnea is one of the most common symptoms associated with CKD. It has a profound influence on the quality of life of CKD patients, and its underlying causes are often associated with a negative prognosis. However, its pathophysiology is poorly understood. While hemodialysis may address fluid overload, it often does not significantly improve breathlessness, suggesting multiple and co-existing alternative issues exist. The aim of this article is to discuss the main pathophysiologic mechanisms and the most important putative etiologies underlying dyspnea in CKD patients. Congestive heart failure, unrecogniz...

Urquhart Patients with chronic kidney disease (CKD) have several comorbidities that require pharmacologic intervention including hypertension, diabetes, anemia, and cardiovascular disease. Advanced CKD patients (eg, treated with hemodialysis) take an average of 12 medications concurrently and are known to suffer from an increased number of medication-related adverse drug events. Recent basic and clinical research has identified altered renal and nonrenal drug clearance in CKD as...

CONCLUSION: The rate of survival was considered low compared others studies and was decreasing over the years, not representing improvements despite technological advances in diagnostic and therapeutic approaches. Advanced age, hypoalbuminemia and anemia are strong predictors of mortality. PMID: 25923752 [PubMed - in process]

Conclusions The eGFR at HD initiation are significantly different according to the used eGFR equations, and the corrected Cockcroft–Gault equation may be the best in defining the eGFR at HD initiation.

Abstract We studied the dialysis practice-patterns with regard to various aspects of chronic kidney disease (CKD) stage 5D, like anemia, mineral bone disease, vaccination, hospitalization, hypertension and cost of therapy. Four hundred and sixty-four adult hemodialysis (HD) patients from various dialysis centers of Mumbai were included in the study. The mean age of the study patients was 47.2 years. Temporary dialysis catheters were the most common initial vascular access. Thirteen percent of prevalent HD patients were on temporary catheters; 33% of patients had history of failure of arterio-venous fistula. The mo...
