Filter by:The purpose of the study is to determine the effect and optimum dose and evaluate the safety of ferric citrate, administered three times daily (TID) immediately after meals for a total daily dose of 4 or 6 grams for 56 days, on serum phosphate (PO4) levels in subjects with end stage renal disease (ESRD).
The objective of this non-interventional study is to confirm that with standard OsvaRen® treatment it is possible to achieve in at least 60% of the patients the levels of phosphorus, total calcium, and iPTH seen in the CALMAG study also in the normal clinical practice.
This study is a regulatory post marketing surveillance in Japan, and it is a local prospective and observational study of patients in hemodialysis who received Fosrenol for hyperphosphatemia. The objective of this study is to assess safety and efficacy of using Fosrenol in clinical practice. A total 3,000 patients will be recruited and followed 5 years.
This study is a regulatory post marketing surveillance in Japan, and it is a local prospective and observational study of patients in continuous ambulatory peritoneal dialysis (CAPD) who have received Fosrenol for hyperphosphatemia. The objective of this study is to assess safety and efficacy of using Fosrenol in clinical practice. This study is also all case investigation of which the enrollment period is one year, and all patients in CAPD who received Fosrenol for hyperphosphatemia will be recruited and followed one year.
Hyperphosphatemia is highly prevalent in PD patients, and it is an independent risk factor for all-cause and cardiovascular mortality in these patients. Effective treatments are limited in suppressing plasma phosphorous. Because of the nearly linear relationship between protein and phosphorus intake, high dietary protein intake (DPI, 1.2-1.3g/kg/d recommended by KDOQI) would load high phosphorus burden in PD patients. It is suggested that hyperphosphatemia is hard to avoid under such a DPI level, even as the patients take sufficient phosphorus blinders and receive high PD dosage. The present study is to investigate whether systemic dietary instruction would show effects on control of hyperphosphatemia in PD patients.
The specific purpose of this study is to describe the characteristics of the K2CG chewing gum, specifically as it relates to duration of gum chewing (exposure), timing of gum chewing in relation to a meal, and dose of K2CG chewing gum.
The study aims to investigate the concept of computer based Phosphate Kinetic Modeling (PKM) in the hemodialysis patient population. This computerized algorithm model was developed as a tool to aid physicians in controlling a hemodialysis patient's phosphate level. Once a subject consents to participate in the study, the subject's dietary phosphate intake will be estimated by the modeling program and the appropriate dose of the phosphate binder calcium acetate (PhosLo) will be recommended accordingly. If necessary, the Ca++ concentration of the dialysate will be changed to remove any excess calcium absorbed as the result of an increase in the PhosLo prescription to control phosphorus.
Aim: Dietary Phosphorus Education Program can improve patients' knowledge, attitude and behavior of phosphorus restriction diet to reduce the risk of hyperphosphatemia and malnutrition of hemodialysis patients. Inclusion criteria: The criteria of subjects are undergoing regular hemodialysis for longer than 3 months at baseline. Subjects' age range is from 20 to 85 years old. Their baseline serum albumin < 4.0 mg/dL, or serum phosphate > 5.0 mg/dL, are eligible for inclusion. Subjects will be enrolled into this trial after signed informed consent. We expect to recruit 60 subjects. Patients will be excluded if they had liver cirrhosis, malignant tumor, can't finish all education sessions and/or can't complete dietary records monthly. We will recruit a control group into this trial, they are eligible for inclusion but don't want to participant education sessions. Intervention protocol: At baseline, the investigators collect demography and pre-test KAP questionnaires among all subjects. If subjects were illiterate then investigator will conduct face-to-face interview and record their answers. Dietary Phosphorus Education is a 6-month program and be implemented by dietitians and investigators, including education, nutritional counseling and dietary records monthly. The first month was intensive weekly education sessions, each 20 to 30 minutes. Second and third month were monthly education sessions, each 20 to 30 minutes. There are total 6 sessions in this trial. The last 3 months will follow-up periods, will collect anthropometry data monthly, biochemistry measurements and 3-day dietary records among all subjects. If subjects were illiterate then investigator will conduct face-to-face interview or phone-interview to complete each dietary record. Investigator collect post-test KAP questionnaires, diet behavior questionnaires and satisfaction questionnaires from subjects in the end of the trial,. If subjects are illiterate then investigators interview subjects and record. This is a 6-months trial and retrospective study to collect anthropometry, biochemical measurements and 3-day dietary records from control subjects monthly.
The hypothesis is that switching calcium based phosphate binders to sevelamer carbonate will be associated with less inflammation including less atherosclerotic plaque inflammation (inflammation of the vessel walls).
Study hypothesis: Nicotinamide inhibits gastrointestinal phosphate absorption and serum phosphate levels of dialysis patients in a dose dependent manner.
