          Abstract

          Background/Aims: Despite effective antibiotic therapy, peritonitis still remains a major problem in peritoneal dialysis (PD). The aim of the present study was to investigate changes of CRP, dialysate leukocytes and IL-6, hyaluronan (HA) and sICAM-1 in dialysate during and after peritonitis and their association to the outcome of peritonitis. Methods: Dialysate IL-6, HA and sICAM-1 were measured at the onset and on day 4, at the end of the treatment and 2 months after onset of peritonitis. Furthermore, CRP and dialysate leukocytes were measured on days 1–4. Results: All measured soluble factors were higher on the first and fourth day than at the end of the treatment. sICAM-1 and HA were lower at the end of the treatment in patients who later had a relapse/re-infection. IL-6 remained higher 2 months after clinically cured peritonitis. CRP and dialysate leukocytes were higher on day 4 in patients with poor outcome. Conclusions: Peritonitis causes increased excretion of soluble factors. Low concentrations of sICAM-1 and HA at the end of the treatment were negative prognostic indicators. Higher IL-6 levels after peritonitis could be a sign of ongoing inflammation in the peritoneal membrane. Delayed decrease in CRP and dialysate leukocytes may indicate poor outcome.

            Plasma and dialysate IL-6 and VEGF concentrations are associated with high peritoneal solute transport rate.

            João E Romão, Marcelo Marcondes Seneda, Peter Stenvinkel … (2002)
            It has been speculated that increased levels of circulating or intraperitoneal pro-inflammatory cytokines such as interleukin 6, and pro-angiogenic vascular endothelial growth factor (VEGF) may contribute to high peritoneal small-solute transport rate (PSTR) in continuous ambulatory peritoneal dialysis (CAPD) patients. In this study we evaluated possible relationships between plasma and dialysate IL-6 and VEGF levels and PSTR. Forty CAPD patients (mean age+/-SD of 58+/-14 years) with no apparent inflammation process or disease, who had been on CAPD for 19+/-15 months (range 3-56 months) were included in the study. Peritoneal equilibration test (PET) was used to evaluate PSTR. Patients were divided into two groups: high-average and high transporters (H/A; D/P(creat)>/=0.65) and low-average and low transporters (L/A; D/P(creat)<0.64). Albumin and IgG clearances were used in the evaluation of permeability to larger solutes. Plasma and overnight dialysate levels of IL-6 and VEGF were measured. Plasma IL-6 (7.6 vs 4.3 pg/ml) and VEGF (342 vs 163 pg/ml) as well as dialysate IL-6 (174 vs 80 pg/ml) and VEGF (96 vs 69 pg/ml) levels were significantly higher in the H/A than in the L/A group. The dialysate appearance of IL-6 and VEGF correlated with D/P(creat), as well as with albumin and IgG clearances. Moreover, significant correlations were noted between dialysate IL-6 and dialysate VEGF levels. The findings of (i) increased plasma and dialysate levels of IL-6 and VEGF in the H/A group compared to the L/A group, (ii) an association between PSTR and both plasma and dialysate IL-6 and VEGF levels, and (iii) a significant correlation between dialysate IL-6 and VEGF concentrations suggest that inflammation, angiogenesis, and peritoneal transport may be interrelated and involved in the pathophysiology of high PSTR in CAPD patients. However, due to the cross-sectional design of this study, the cause and effect relationships between plasma and dialysate IL-6 and VEGF concentrations and high PSRT remain unclear.

              Peritoneal transport in CAPD patients with permanent loss of ultrafiltration capacity.

              Olof Heimburger, Jacek Waniewski, Andrzej Warynski … (1990)
              During a 10 year period, 14 out of 227 patients (6.2%) undergoing continuous ambulatory peritoneal dialysis (CAPD) developed permanent loss of ultrafiltration capacity (UFC). The risk of UFC loss increased from 2.6% after one year to 30.9% after six years of treatment. A six hour, single dwell study with glucose 3.86% dialysis fluid was carried out in nine of the UFC loss patients and in 18 CAPD patients with normal UFC. Intraperitoneal dialysate volumes were calculated using 131I-tagged albumin (RISA) as volume marker with a correction applied for its elimination from the peritoneal cavity. The RISA elimination coefficient (KE), which can serve as an estimation of the upper limit of the lymphatic flow, was also calculated. Diffusive mass transport coefficients (KBD) for investigated solutes (glucose, creatinine, urea, potassium, total protein, albumin and beta 2-microglobulin) were calculated during a period of dialysate isovolemia. Two patterns of UFC loss were observed: (a) seven patients had high KBD values for small solutes resulting in rapid uptake of glucose, whereas KBD values for proteins were normal; (b) two patients had normal KBD values but a threefold increase both in the fluid reabsorption rate and KE. We conclude that loss of the osmotic driving force (due to increased diffusive mass transport for small solutes) and increased fluid reabsorption (possibly due to increased lymphatic reabsorption) are the two major causes of permanent loss of UFC in CAPD patients.
