The Italian nephrology has a long tradition and experience in the field of dietetic-nutritional therapy (DNT), which is an important component in the conservative management of the patient suffering from a chronic kidney disease, which precedes and integrates the pharmacological therapies. The objectives of DNT include the maintenance of an optimal nutritional status, the prevention and/or correction of signs, symptoms and complications of chronic renal failure and, possibly, the delay in starting of dialysis. The DNT includes modulation of protein intake, adequacy of caloric intake, control of sodium and potassium intake, and reduction of phosphorus intake. For all dietary-nutritional therapies, and in particular those aimed at the patient with chronic renal failure, the problem of patient adherence to the dietetic-nutritional scheme is a key element for the success and safety of the DNT and it can be favored by an interdisciplinary and multi-professional approach of information, education, dietary prescription and follow-up. This consensus document, which defines twenty essential points of the nutritional approach to patients with advanced chronic renal failure, has been written, discussed and shared by the Italian nephrologists together with representatives of dietitians (ANDID) and patients (ANED).
To clarify the role of chronic anaemia in the pathogenesis of the left ventricular hypertrophy (LVH) of chronic uraemia, nine normotensive dialysed patients were studied before and 3 and 6 months after start of intravenous treatment with recombinant human erythropoietin (rHuEpo). M-Mode echocardiographic estimations of left ventricular mass indices (LVMi) and plasma noradrenaline determinations were made at 3 and 6 months, and total blood volume (TBV) only at 6 months. Resting haemoglobin values were 5.9 +/- 1.3 (SD) g/dl, increased within 3 months to 10.2 +/- 1.2 (P less than 0.001), then remained unchanged. Baseline LVMi was 115 +/- 18 g/m2 body surface area (b.s.a.) and decreased significantly (P less than 0.0025) over the entire period to a final value of 78 +/- 13 g, which did not differ from the average value for 19 healthy controls. Resting plasma noradrenaline was 1.45 +/- 0.44 pmol/ml and did not change significantly, although values were reduced at the 3rd month, when decreased heart rates and slightly and non-significantly increased blood pressures were recorded. TBV did not vary because the increased erythrocyte mass was compensated for by parallel decreases in plasma volume. These data demonstrate the existence of a cause-effect relationship between uraemic anaemia and LVH, although the precise mechanism remains unknown. Amelioration of anaemia with rHuEpo, by allowing recovery from the attendant LVH, might improve long-term cardiovascular prognosis in some dialysed uraemic patients.
IntroductionIncremental dialysis consists in prescribing a dialysis dose aimed towards maintaining total solute clearance (renal + dialysis) near the targets set by guidelines. Incremental peritoneal dialysis (incrPD) is defined as one or two dwell-times per day on CAPD, whereas standard peritoneal dialysis (stPD) consists in three-four dwell-times per day.Patients and methodsSingle-centre cohort study. Enrollement period: January 2002–December 2007; end of follow up (FU): December 2012. Inclusion criteria: incident patients with FU ≥6 months, initial residual renal function (RRF) 3–10 ml/min/1.73 sqm BSA, renal indication for PD.ResultsMedian incrPD duration was 17 months (I–III Q: 10; 30). There were no statistically significant differences between 29 patients on incrPD and 76 on stPD regarding: clinical, demographic and anthropometric characteristics at the beginning of treatment, adequacy indices, peritonitis-free survival (peritonitis incidence: 1/135 months-patients in incrPD vs. 1/52 months-patients in stPD) and patient survival. During the first 6 months, RRF remained stable in incrPD (6.20 ± 2.02 vs. 6.08 ± 1.47 ml/min/1.73 sqm BSA; p = 0.792) whereas it decreased in stPD (4.48 ± 2.12 vs. 5.61 ± 1.49; p < 0.001). Patient survival was affected negatively by ischemic cardiopathy (HR: 4.269; p < 0.001), peripheral and cerebral vascular disease (H2.842; p = 0.006) and cirrhosis (2.982; p = 0.032) and positively by urine output (0.392; p = 0.034). Hospitalization rates were significantly lower in incrPD (p = 0.021). Eight of 29 incrPD patients were transplanted before reaching full dose treatment.ConclusionsIncrPD is a safe modality to start PD; compared to stPD, it shows similar survival rates, significantly less hospitalization, a trend towards lower peritonitis incidence and slower reduction of renal function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
