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

The phagocytic activity of peritoneal neutrophils was assessed using Bacto-Latex in 50 patients with chronic renal failure treated with intermittent peritoneal dialysis, and in 30 control patients with normal renal function. In the group of patients treated with peritoneal dialysis 20 were additionally investigated while developing peritonitis. A significant decrease in the phagocytic activity of neutrophils was observed in the both dialysed groups, as compared with control subjects. Moreover, the phagocytic activity was significantly lower in patients with peritonitis as compared with dialysed patients without this complication. 相似文献

Increased oxidative stress is a well-known phenomenon in dialysis patients. However, the contribution of hypertension to the oxidative stress in peritoneal dialysis patients has not yet been assessed. The present study aimed to investigate if hypertension had an additional effect on oxidative stress in peritoneal dialysis patients. A total of 50 patients treated with peritoneal dialysis were divided into two groups: The patients with mean of last three blood pressure results as 135/90 mmHg and above were considered hypertensive, the patients with lower blood pressure were considered normotensive. The control group included 25 healthy individuals. Serum malondialdehyde (MDA), advanced oxidation protein product (AOPP), myeloperoxidase (MPO), catalase (CAT) and glutathione peroxidase (GSH-Px) levels were measured in all groups. MDA level, an indicator of lipid peroxidation, was significantly higher in the hypertensive group compared to the control group, while the increase in the normotensive group was not significant. However, the difference between the hypertensive and normotensive groups was significant. The levels of AOPP, an indicator of protein oxidation level, and MPO, an indicator of neutrophil activation, were not different between the groups, while the activities of antioxidant CAT and GSH-Px decreased in both normotensive and hypertensive groups compared to the control group, and there was no significant difference between the patient groups. This study shows that both normotensive and hypertensive peritoneal dialysis patients have increased-oxidative stress and decreased antioxidant levels and hypertension might have an additional effect on oxidative stress by increasing MDA level in peritoneal dialysis patients. 相似文献

The present study describes our experience with CAPD in an unselected group of patients presenting with endstage renal failure. Twenty-three consecutive patients were offered CAPD, in-center, and home hemodialysis. Twenty-two patients selected CAPD, including 14 patients more than 60 years of age, four patients with diabetes, and one with multiple myeloma. CAPD training was performed in an out-of-hospital office facility. One patient returned to hemodialysis following the development of resistant Pseudomonas peritonitis, two patients died of a myocardial infarction, and one patient died with a GI bleed. The other 18 patients are doing well. Assessment of 17 patients maintained on therapy for four months or more revealed that the patients are less depressed, less organic, and have fewer physical symptoms than previously reported for a comparable group of patients maintained on hemodialysis for a similar period of time. In conclusion, CAPD can be successfully employed, at least for the initial months of therapy, to treat the vast majority of patients with endstage renal disease. CAPD training and follow-up care can be provided in an out-of-hospital office facility. 相似文献

A case-control study on chronic Chagas heart disease (CCHD) was carried out between 1997 and 2005. Ninety patients over 50 years of age were examined for factors related to (CCHD). Fourty-six patients (51.1%) with Chagas heart disease (anomalous ECG) were assigned to the case group and 44 (48.9%) were included in the control group as carriers of undetermined forms of chronic disease. Social, demographic (age, gender, skin color, area of origin), epidemiological (permanence within an endemic zone, family history of Chagas heart disease or sudden death, physical strain, alcoholism, and smoking), and clinical (systemic hypertension) variables were analyzed. The data set was assessed through single-variable and multivariate analysis. The two factors independently associated with heart disease were age--presence of heart disease being three times higher in patients over 60 years of age (odds ratio, OR: 2.89; confidence interval of 95%: 1.09-7.61)--and family history of Chagas heart disease (OR: 2.833, CI 95%: 1.11-7.23). Systemic hypertension and gender did not prove to hold any association with heart disease, as neither did skin color, but this variable showed low statistical power due to reduced sample size. 相似文献

Acid phosphatase, beta-D-Glucuronidase and N-acetyl-beta-D-glucosaminidase were assessed cytochemically in peritoneal macrophages obtained from 50 patients with end-stage renal failure treated by intermittent peritoneal dialysis and from 30 control subjects with normal renal function. A statistically significant increase in beta-D-glucuronidase activity accompanied by a decrease in acid phosphatase activity were observed in peritoneal macrophages of dialysed patients, as compared with the control group. In patients with dialysis-associated peritonitis, the activity of N-acetyl-beta-D-glucosaminidase was significantly higher than that observed in the same patients during the complication-free period of the treatment. 相似文献

BACKGROUND: Helicobacter pylori infection in chronic renal failure patients has been linked to peptic ulcer and gastric neoplasia after kidney transplantation. It may also contribute to the accelerated arteriosclerosis that is usual in this population. Few data are available on the usefulness of noninvasive diagnostic tests for H. pylori infection in dialyzed patients, especially regarding the new fecal antigen detection tests. The objective of this study was to determine the efficacy of a noninvasive test for H. pylori infection in patients with chronic renal failure. METHODS: Eighty-six patients were included in a cross-sectional study. Urea breath test, serology and three fecal tests--FemtoLab H. pylori (Connex, Germany), Premier Platinum HpSA (Meridian, USA) and Simple H. pylori (Operon SA, Spain) were performed. Helicobacter pylori status was determined by concordance of the tests. Sensitivity, specificity and positive and negative predictive values were calculated for each test. RESULTS: Sensitivity, specificity, positive and negative predictive values were 94%, 96%, 94% and 96% for the urea breath test; 97%, 64%, 66% and 97% for serology; 86%, 100%, 100% and 91%, for FemtoLab H. pylori; 58%, 96%, 91% and 76% for Premier Platinum HpSA and 61%, 78%, 74% and 67% for Simple H. pylori. CONCLUSIONS: The urea breath test seems to be the most reliable diagnostic method for H. pylori infection in patients with chronic renal failure. Serology has a low specificity, and the results of the fecal tests vary widely. 相似文献

Over a 3 1/2-year period the permanent Tenckhoff catheter was used in 66 patients (32 men and 34 women) maintained on chronic peritoneal dialysis for periods from 2 1/2 to 36 1/2 months; 57 patients had dialysis in hospital for 20 to 24 hours twice a week and the other 9 had dialysis at home for 10 to 12 hours four times a week. While the Tenckhoff catheter was in place 14 patients received a renal transplant; for 13 who required peritoneal dialysis during the post-transplant phase the Tenckhoff catheter was used. In nine patients abdominal surgery did not interfere with the continuation of peritoneal dialysis via the Tenckhoff catheter. From a total of 5067 dialyses 40 positive cultures were reported (0.8%). Peritonitis was clinically evident on only 14 occasions (0.28%). Permanent catheter obstruction developed in 16 patients, in 11 of whom it was related to peritonitis. With the introduction of the permanent Tenckhoff catheter long-term peritoneal dialysis has become a simple, safe and painless procedure, suitable for virtually all patients who require maintenance dialysis. 相似文献
