Cytology of peritoneal fluid from patients on continuous ambulatory peritoneal dialysis 总被引:1,自引:0,他引:1
Peritoneal fluids from 41 patients on continuous ambulatory peritoneal dialysis (CAPD) were examined. The patients were divided into a short-term group (18 patients with CAPD up to one year) and a long-term group (23 patients with CAPD for one to seven years). Peritoneal fluids from a control group, consisting of ten nondialysis patients with ascites, were also examined. The cellular background of the peritoneal fluids and, in particular, the morphology of the mesothelial cells were studied. The following were found to be significantly increased in the CAPD groups: background lymphocytes, mesothelial exfoliation in three-dimensional clusters, mesothelial nuclear size and the number of mesothelial nucleoli. All of these features increased slightly with an increased duration of the dialysis. These findings emphasize that peritoneal dialysis of any duration can induce significantly atypical changes in mesothelial cells. 相似文献

Experience in the use of continuous ambulatory peritoneal dialysis (CAPD) for the treatment of end stage renal failure in Nottingham was reviewed. During six years 150 patients aged from 11 to 73 received this type of treatment. At three years patient actuarial survival was 69% and CAPD technique survival was 41%. Although CAPD was satisfactory as a first treatment for many patients, its long term use was possible in only a few. Actuarial survival of patients who changed to haemodialysis was 64% at one year after the change, suggesting that unsuccessful CAPD increased the risk of death. Hospital haemodialysis was the only suitable form of treatment for most patients in whom CAPD had been abandoned. British renal units have adopted CAPD to a much greater extent than those in Europe, but care in the selection of patients is necessary to reduce mortality, and many patients may eventually need hospital haemodialysis. Greater numbers of hospital haemodialysis places will probably have to be made available to meet this extra demand. 相似文献

The use of continuous ambulatory peritoneal dialysis (CAPD) in children has proved beneficial. However, peritonitis remains the major complication. A review of the incidence of peritonitis in 55 children (mean age 9.6 years) who underwent CAPD between 1978 and 1984 showed that there were 67 episodes of peritonitis (1 per 9.4 patient-months) in 33 of the 55. Three patients accounted for 22 of the episodes. In all cases, treatment with antibiotics, given intraperitoneally, was successful. Cephalothin was routinely given for infections due to gram-positive organisms, tobramycin for infections due to gram-negative organisms. Peritonitis recurred in seven patients, of whom five had to have their catheters replaced because of associated chronic infections of the deep peritoneal cuff, the exit site or the catheter tunnel. Although peritonitis was a common complication of CAPD in this population, it did not affect the success of the technique. 相似文献

This paper reports a case of infection byHistoplasma capsulatum apparently restricted to the peritoneum in a woman submitted to continuous ambulatory peritoneal dialysis. Diagnosis was established by culture of dialysis fluid and peritoneal nodule and by histopathologic examination. 相似文献

A questionnaire based survey in patients receiving continuous ambulatory peritoneal dialysis showed that there was an increased incidence of upper respiratory tract symptoms (suggestive of viral illness) in the 14 days before the development of peritonitis. No other factors were identified that might distinguish patients who develop peritonitis. The possibility that viral infections predispose to peritonitis by altering host defence mechanisms in patients receiving this form of renal replacement therapy warrants further study. 相似文献

The kinetics of absorption of intraperitoneally administered insulin were studied in nine uraemic insulin-dependent diabetics undergoing continuous ambulatory peritoneal dialysis (CAPD). In each of three studies 20 U of regular insulin was directly injected as a bolus into the peritoneal cavity through an indwelling Tenckhoff catheter. In two procedures the insulin injection was followed by the instillation of either 2 litres of 1.5% dextrose dialysates or 2 litres of 4.5% dextrose dialysate. In the third 20 ml of saline was used to flush the tubing. Plasma free insulin values rose more rapidly and reached significantly higher concentrations (55.6 +/- 18.8 mU/l) when the insulin had been injected into an empty peritoneal cavity than when it was followed by dialysate. These differences were observed despite the fact that most of the insulin injected was retained by the patients. Since the plasma insulin values did not differ after instillations of dialysate containing 1.5% and 4.5% dextrose, the osmolality of the dialysate seemed not to affect insulin absorption, and the dilution of the insulin probably delayed its transfer through the peritoneum. These findings suggest that insulin given intraperitoneally to patients undergoing CAPD will be most effective if it is given into an empty peritoneal cavity at least 30 minutes before the dialysate is instilled. 相似文献

Thirty eight patients aged over 60 with end stage renal disease were treated by continuous ambulatory peritoneal dialysis for up to three years. Most of these patients, because of their age or coexisting diseases, had been considered to be unsuitable for haemodialysis by the criteria used before the advent of continuous ambulatory peritoneal dialysis in 1980. Actuarial patient survival at one and two years was 72% and 61% respectively, and only two patients were permanently transferred to haemodialysis. Twenty one of the 23 survivors were fully rehabilitated, the remaining two being partially disabled but living at home. Continuous ambulatory peritoneal dialysis permits more liberal selection of patients with end stage renal disease for renal replacement treatment with excellent survival and rehabilitation and without overburdening scarce hospital haemodialysis facilities. 相似文献
