Background. Peritoneal dialysis (PD) is associated with a depression of T cell function, as suggested by the impaired production of cytokines by Th cells collected from PD patients. Although treatment biocompatibility could be implicated in this immune dysfunction, it has been poorly investigated, thus far. Therefore, we undertook a study aiming to analyze the effects of different peritoneal dialysis fluids on the Th1/Th2 balance in PD patients. Methods. Twenty three patients on continuousambulatory peritoneal dialysis (CAPD) were evaluated. Seven patients were on CAPD with icodextrin solution (ICO-PD), seven with glucose and lactate/bicarbonate-buffered solution (LAC/BIC-PD), and nine with glucose and lactate-buffered solution (LAC-PD). The Th1/Th2 balance was evaluated by measuring IFN-γ(Th1 subset) and IL-4 (Th2 subset), both in circulating and peritoneum-derived Th lymphocytes unstimulated or stimulated by phytohemoagglutinin (PHA). Moreover inflammatory, nutritional and dialysis-related parameters were recorded. Eight normal subjects comprised the control group (CON). Results. Circulating T cells: IFN-γ was significantly lower in the LAC-PD group (p
