Metabolic acidosis (MA) is common in chronic renal insufficiency (CRI) patients, and its pattern changes as renal function deteriorates. Although the prevalence of acidosis in peritoneal dialysis has been reported to be rather high, the causes of it have not been well studied. The present study was performed to examine the prevalence of metabolic acidosis in our continuous ambulatory peritoneal dialysis (CAPD) patients and its possible causes. ⋯ Our study suggested that CAPD patients with better RRF were more susceptible to metabolic acidosis, which was characterized by normal anion gap and hyperchloremia. Thus, we speculate that renal loss of bicarbonate may to a large extent be responsible for the occurrence of MA in these patients.

Comparative Study
Changes in plasma interleukin-18 by direct hemoperfusion with polymyxin B-immobilized fiber in patients with septic shock.
Polymyxin B-immobilized fiber (PMX-F) treatment is reported to be safe and effective in patients with severe sepsis and septic shock. The aim of the present study was to determine whether plasma levels of interleukin (IL)-18, which is linked with sepsis, are associated with plasma endotoxin levels and sepsis-related scores and whether PMX-F treatment affects these variables in patients with septic shock. ⋯ IL-18 may be associated with the severity of septic shock, and PMX-F treatment is effective in reducing the IL-18 level in patients with septic shock.
