Filter by:The purpose of this study is to develop recommendations to assist in improving the current peritoneal dialysis (PD) program in a Hospital in Chinandega, Nicaragua. This project will consist of a needs assessment, a review of aggregate quantitative patient data from hospital records, and a knowledge, attitudes, and practices (KAP) assessment for medical providers, laboratory technicians, patients and primary caregivers. The final report will be used to obtain funding for the implementation of the recommendations.
Hypothesis: The investigators hypothesize that regular monitoring of BIA adds value to the management of fluid status in PD patients Objectives of the study: The objective is to show that in patients where the additional information of body composition is available to the clinician that the ECFv is maintained within pre-agreed limits, ~ 1 liter, over the observation period of 12 months. SCIENTIFIC BACKGROUND: Low peritoneal ultrafiltration, and by inference low sodium removal, is associated with worse outcomes in PD. Equally, excessive fluid removal is a risk factor for dehydration and loss of residual renal function. Current guidelines have advocated a daily UF volume of 1litre; their blunt application could lead to either inappropriate early loss of residual function or modality transfer. There is a significant need for evidence on how to best manage fluid status in PD patients, both in terms of an appropriate clinical strategy and also a simple but reproducible tool to guide clinicians in how to apply this strategy. It is likely that BIA will become the standard tool to aid clinicians in assessing fluid status. It is simple to perform, intervention studies have demonstrated its ability to identify changes in fluid status in response to changes in therapy and it is a powerful predictor of patient survival. There is, however a clear need at this stage for proof of principle studies to establish its true potential for added value in the routine management of patients. Body composition changes spontaneously with time on PD. Short term changes in hydration (specifically extracellular fluid volume, ECFv) combined with medium term changes in muscle and fat make it difficult for the clinician to be sure if fluid status is stable. It is anticipated that regular BIA measurements will aid the clinician in managing this problem over and above monitoring of weight and fluid status. By randomizing patients into two groups who have regular BIA measurements, one of which the BIA data is available to the clinician it will be possible to see if these spontaneous changes in body composition can be accounted for.
Hyperphosphatemia is frequently seen in patients with end-stage renal disease (ESRD). Hyperphosphatemia usually results in a high calcium-phosphorus product (CPP) which may subsequently lead to artery and become a risk factor of cardiovascular complications. Alendronate, due to its effect of inhibiting osteoclasts, is approved for treatment of osteoporosis. Previous reports found the use of bisphosphonates could suppress arterial calcification in hemodialysis dialysis patients. The aim of this study is to evaluate the safety and efficacy of alendronate to suppress coronary artery and aortic calcifications, as well as to improve bone density in chronic peritoneal dialysis (PD) patients. This study will include ESRD patients who had received maintenance PD for more than 3 months, have high CPP level (≧55), and have chest X-ray proven aortic calcification or coronary artery calcification. All participants are randomly allocated to either group 1 or group 2. Group 1 patients receive alendronate 70 mg once weekly in the first 16 weeks, while group 2 patients receive the same dose of drug every week in the second 16 weeks. The extent of coronary artery and aortic calcification is evaluated by using multi-detector spiral computed tomography, whereas bone mineral density is measured by dual-energy X-ray absorptiometry. Both examinations are performed at week 0, 16 and 32 for each participant. Laboratory studies and possible adverse reactions were regularly monitored. We expect that alendronate can alleviate the progression of arterial calcification or even improve it. Bone density may also be improved after treatment. Besides, we wish to find the independent factor(s) influencing the efficacy of alendronate. These results may help clinical physicians for early intervention and prevention of cardiovascular complications in ESRD patients.
