Nutritional-inflammation status and resistance to erythropoietin therapy in haemodialysis patients.

Background: Chronic kidney disease patients who are resistant to erythropoietin (EPO) treatment may suffer from malnutrition and/or inflammation.

Methods: In a cross-sectional study of haemodialysis patients, we investigated the relationship between the natural logarithm of the weekly EPO dose normalized for post-dialysis body weight and outcome measures of nutrition and/or inflammation [BMI, albumin and C reactive protein (CRP)] by means of multiple linear regression analysis. On the basis of the decile distribution of weekly EPO doses, we also evaluated four groups of patients: untreated, hyper-responders, normo-responders and hypo-responders.

Fibrinogen and calcium x phosphate product are predictors of cardiovascular events in the CAPD population.

Objective: Plasma fibrinogen (Fib) and calcium x phosphate product have emerged as cardiovascular (CV) event predictors in hemodialysis (HD) patients, but their role in peritoneal dialysis (PD) is less studied.

Design And Subjects: We investigated whether Fib and calcium x phosphate product predict CV events in a prospective cohort study of 47 continuous ambulatory PD (CAPD) patients (mean follow-up 34.6 months).
