Resistive index and antihypertensive therapy in kidney transplantation.

Objectives: To investigate in kidney transplanted patients any possible correlation between intrarenal Doppler Resistive Index (RI) and arterial hypertension (AH); to detect any possible angiotensin converting enzime inhibitors (ACE-I)/angiotensin receptor blockers (ARB) influence on RI.

Material And Methods: Our retrospective study took into consideration 80 consecutive renal allograft sonography scans of 54 patients (37 males) under observation in our centre over a one-year period (2003). Patients were evaluated about their renal function by means of serum creatinine dosage (mg/dL).

[Two-chamber hemodiafiltration: comparison between exogenous reinfusion (PFD) and endogenous reinfusion (HFR)].

Purpose: This research aimed to compare two highly efficient dialysis techniques, paired filtration dialysis (PFD) and on-line hemodiafiltration with endogenous reinfusion (HFR) to evaluate the possible differences from a clinical, rehabilitative and managerial point of view.

Methods: The study was carried out on 14 patients (aged 40-65 yrs) six patients underwent PFD and eight patients underwent HFR. Patients on PFD came from low-flux hemodialysis (HD), while patients on HFR came either from PFD (n=5) or from low-flux HD (n=3).

Recombinant human erythropoietin resistance in hemodialysis. Effects of paired filtration dialysis.

A percentage of hemodialysis (HD) patients are resistant to recombinant human erythropoietin (rHuEPO), a phenomenon that occurs less frequently in patients dialyzed with biocompatible membranes (M) and in peritoneal dialysis. The authors evaluated the effects of paired filtration dialysis (PFD)--a dialysis technique based on the use of an emophan M in conjunction with a polysulphone M--on erythropoiesis in HD patients resistant to rHuEPO. Twelve HD patients with anemia resistant to long-term therapy with rHuEPO (200.

Peritoneal dialysis effluent, cytokine levels, and peritoneal mesothelial cell viability in CAPD: a possible relationship.

Recent studies have emphasized the role of peritoneal mesothelial cell (PMC) in peritoneal immune defense mechanisms in continuous ambulatory peritoneal dialysis (CAPD). The aim of this study was to evaluate a possible relationship between peritoneal dialysis effluent (PDE), cytokine (Cy) levels, and PMC viability and their impact on peritonitis morbidity. Fifteen patients initiating CAPD for end-stage renal failure participated in the study.
