| Popis: | Objective Intraperitoneal phagocytes play an important role in local defense in preventing continuous ambulatory peritoneal dialysis (CAPD) peritonitis. This study therefore investigates the effect of the conventional lactate-based dialysis solution-pH 5.2 (LBDS-pH 5.2) and a bicarbonate-based dialysis solution (BBDS) on various cell functions. Design We studied C5a-induced actin polymerization (AP) as a measure of the cytoskeletal alteration, phagocytosis of zymosan particles, and chemotaxis in neutrophils incubated in either LBDS-pH 5.2, LBDS-pH 7.4, or BBDS-pH 7.4, comparing the data with cells treated with phosphate-buffered saline-pH 7.4 (PBS-pH 7.4) as a control. Subjects Polymorphonuclear neutrophils (PMNs) were isolated from the blood of healthy donors and incubated with dialysis solution prior to the experiment. Results C5a-induced AP was dramatically inhibited in PMNs incubated in LBDS-pH 5.2, paralleled by a complete inhibition of phagocytosis and C5a-induced chemotaxis. In comparison, BBDS improved AP to values above the control and also nearly normalized phagocytosis. Chemotaxis markedly improved in cells treated with the low glucose-containing BBDS (Bic 20), but was still inhibited in PMNs incubated in the BBDS containing high glucose concentrations (Bic 30). Conclusion In comparison with conventional lactate-based dialysis solution-pH 5.2, bicarbonate-based dialysis solution at low osmolality better preserves neutrophil functions that involve the cytoskeleton. |
