The effect of continuous ambulatory peritoneal dialysis on serum CA-125 levels.
Malignant and non-malignant serosal fluids were found to be associated with high serum levels of CA-125, suggesting that the presence of fluid in the serosal cavities may stimulate its release. In this study, we investigated the relationship between serum CA-125 levels and peritoneal irritation during continuous ambulatory peritoneal dialysis (CAPD). We performed a clinical study in 24 stable patients (15 amenstrual females and 9 males), aged 46 +/- 14 years on CAPD. The control group consisted of 32 healthy volunteers (20 females, 12 males) aged 44 +/- 12 years. CA-125 levels were determined prior to the CAPD dwell (without dialysate in abdomen) and during the CAPD dwell (dialysate in abdomen 4 hours after). As a result, serum CA-125 levels were found to be 14.86 +/- 5.98 U/ml and 15.23 +/- 6.05 U/ml respectively, whereas it was 8.32 +/- 5.54 U/ml in the control group. Serum CA-125 levels were found to be significantly elevated in CAPD patients when compared with healthy volunteers. However, serum CA-125 levels detected prior to and after CAPD did not differ between the groups. Interestingly, all of the patients in our study group were detected to have normal serum CA-125 levels (< 35 U/ml). We concluded that CAPD-induced abdominal artificial ascites did not affect serum levels of CA-125. Moreover, short and non-inflammatory mechanical pressures in the CAPD procedure do not have any effect on serum CA-125 levels.
