INTRODUCTION Peritoneal dialysis (PD) is a life-saving treatment for end-stage renal disease patients. However, cardiovascular disease remains the major cause of morbidity and mortality in PD patients. It is now realized that chronic asymptomatic intravascular hypervolemia is an important cause of cardiovascular disease in PD patients. OBJECTIVES To determine the effects of treating asymptomatic fluid overload on blood pressure, hospitalization and cardiovascular morbidity in PD patients. HYPOTHESIS The investigators hypothesize that treating asymptomatic fluid overload could improve the clinical outcome of PD patients. DESIGN & SUBJECTS This is an open label randomized control trial. The investigators plan to recruit 60 PD patients with asymptomatic fluid overload, defined as overhydration (OH) ≥ 2 liters. Patients will be randomized to active fluid management (treatment arm) or conventional management (control arm). STUDY INSTRUMENTS Overhydration will be identified by bioimpedance spectroscopy. INTERVENTIONS For the treatment arm, active fluid management includes dietary counseling, diuretics, and intensive dialysis regimen. For the control arm, patients will only receive dietary counseling. Patients will be followed for one year. MAIN OUTCOME MEASURES Blood pressure control, number of hospital admission and duration of hospitalization for all cause, and hospitalization for cardiovascular disease during the study period. DATA ANALYSIS Blood pressure control will be compared by Student's t test. Hospitalization data will be compared by non-parametric Mann Whitney U test. EXPECTED RESULTS The study will determine the benefit of treating asymptomatic fluid overload in PD patients.
Patients with peritoneal dialysis will be administered an IV glucose-injection to evaluate the haemodynamic impact of this injection. The patients will be matched with healthy volunteers.
This is a Phase IV study evaluating triglyceride levels in peritoneal dialysis patients.
Hypothesis In peritoneal dialysis (PD) patients, malnutrition, inflammation and atherosclerotic cardiovascular disease commonly coexist. The triad has been coined the "MIA syndrome". Proinflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha), plays a central role in the pathogenesis of the MIA syndrome. Thalidomide selectively inhibits the production of TNF-alpha and represents a valuable anti-cytokine therapy. Specific Aim To study the effect of thalidomide in attenuating or reversing malnutrition and systemic inflammation in PD patients. Research Plan Design: Double-blinded randomised prospective placebo control trial. Setting: Renal unit of a university teaching hospital. Subjects: Sixty prevalent PD patients with evidence of malnutrition. Interventions: Patients will be randomised to receive either oral thalidomide 100 mg nocte or placebo. Main outcome measures: Patients will be followed for 1 year. Nutritional parameters including serum albumin, subjective global assessment, malnutrition-inflammation score, normalised protein nitrogen appearance, fat-free edema-free body mass and anthropometry measurements will be monitored. Systemic inflammatory markers such as serum C-reactive protein and IL-6 will be assayed. Hospitalisation, cardiovascular events, and overall patient survival will also be compared during study period. Expected Outcome Nutritional parameters and markers of systemic inflammation are expected to improve with thalidomide therapy. The magnitude of improvement in nutrition, as well as patient morbidity, will be compared with placebo. In Hong Kong, 80% of end-stage renal failure patients are treated with PD. Malnutrition, cardiovascular disease and systemic inflammatory response are all common in our clinical practice. They are major causes of patient morbidity and mortality. As a readily available anti-cytokine therapy, thalidomide may represent a valuable treatment of the MIA syndrome. The proposed study will provide important insight on the clinical benefit of thalidomide treatment in malnourished PD patients, which accounts for about one-third of our dialysis population.
