  • Title: [Parameters of blood acid: base balance and adequacy of continuous ambulatory peritoneal dialysis as well as dietary intake and nutritional status].
    Author: Grzegorzewska AE, Mariak I.
    Journal: Pol Merkur Lekarski; 1999 Apr; 6(34):176-81. PubMed ID: 10391054.
    Abstract:
    The purpose of studies was: 1) an evaluation of acid-base balance parameters of capillary blood in the course of CAPD treatment with the correlation analysis between these parameters and indices of CAPD adequacy, dietary intake, nutritional status and selected clinical and laboratory findings, 2) an influence of dialysis solution containing amino acids on capillary acid-base balance. The purpose first was realized in 55 patients treated CAPD up to 24 months, the second one-in 8 CAPD patients. Kt/V, PCR, total creatinine clearance, efficacy number and clinical laboratory scores (Missouri system) were used as CAPD adequacy indices. Dietary intake was evaluated from diet histories. Indices of nutritional status included total body mass, blood concentration of total protein, albumin, Fe, ferritin and cholesterol as well as TIBC. It was shown that compensated metabolic acidosis is the most common finding in patients on CAPD. Acid-base parameters do not depend significantly on Kt/V and total creatinine clearance but there is a negative correlation between HCO3- and PCR as well as between H+ concentration and efficacy number. There is no relationship between dietary intake and acid-base parameters of CAPD patients. The worse acid-base status the greater azotemia and the higher removal of nitrogenous compounds in dialysate. It was confirmed that amino acid dialysis solution deteriorates metabolic acidosis but it can be avoided by the use of oral alkalizating drugs.
