Outcomes

Primary Outcome Measures

Efficacy and safety of Regpara in chronic dialysis patients with high blood levels of parathyroid
Regpara those taking 25 mg per day to get the default dose and the dose is adjusted according to the levels of calcium and parathyroid hormone. By adjusted dose of 25 mg every 3 weeks (weeks 3, 6, 9) for a period of 12 weeks, the drug is between 25-75 mg dose, with a maximum dose of not more than 100 mg per day .

Secondary Outcome Measures

Efficacy of the REGPARA in reducing the FGF23 level
The Regpara those taking 25 mg per day to get the default dose and the dose is adjusted according to the levels of calcium and parathyroid hormone. By adjusted dose of 25 mg every 3 weeks (weeks 3, 6, 9) for a period of 12 weeks, the drug is between 25-75 mg dose, with a maximum dose of not more than 100 mg per day .

5. Study Description

Brief Summary
The dialysis patient of chronic kidney disease and parathyroid hormone levels greater than or equal to 800 Pg per ml were divided into two groups by randomized 1:1, one group to receive medication and a control group that did not receive the medication. By group to receive in those taking 25 mg per day to get the default dose and the dose is adjusted according to the levels of calcium and parathyroid hormone. By adjusting the dose of 25 mg every 3 weeks for a period of 12 weeks, the drug is between 25-75 mg dose , with a maximum dose of not more than 100 mg per day (weeks 3, 6 , 9). After a follow-up treatment in weeks 12, 24 and 36 with an blood,ultrasound test parathyroid glands , abdominal x-ray side . To evaluate the changes without the drug .Unless the track during treatment the patients with low blood calcium levels over 8.4 mg per dL . No dose adjustment . regpara while if blood calcium levels less than 7.5 mg per deciliter . Must be stop taking medication for patients in the control group will receive standard treatment . Which consisted of dose vitamin D sterol and parathyroid surgery . Unable to control the level of parathyroid hormone with vitamin D sterol. While participating in the research are not allowed to adjust the amount of vitamin D sterol in the two groups . But the amount of dialysate calcium phosphate binders and can be adjusted as appropriate to healthcare is fine .
Detailed Description
The renal impairment is caused FGF-23 resistance to the congestion of phosphate and stimulate the secretion of parathyroid hormone (PTH) from the parathyroid gland causes secondary hyperparathyroidism. They also found that high levels of FGF-23 is also a risk factor of vascular calcification. The Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) is a disorder caused by renal impairment cause abnormalities occurring in the body. Can be summarized into three main parts as follows : 1) The disorders of minerals and hormones (laboratory abnormalities) such as hyperphosphatemia, secondary hyperparathyroidism. 2 ) The disorders of bone (bone abnormalities) , formerly known as renal osteodystrophy 3) The vascular calcification which results happened increase the risk of heart disease and stroke (cardiovascular disease) , broken bones (fractures) and death rate (mortality). The secondary hyperparathyroidism. PTH secretion from parathyroid glands are more than normal and a major cause of the congestion of phosphate , reduced levels of 1,25-dihydroxyvitamin D [1,25 (OH) 2D] in the blood and a decrease in blood calcium levels decreased calcium levels in the blood is low. will result in a calcium (calcium sensing receptor or CaSR) on parathyroid glands make parathyroid cell signaling and increased PTH secretion . That PTH increased continuously in the long run will cause the destruction of the bone called bone decay know "osteitis fibrosa". Some patients with a bone fracture. Important characteristics of osteitis fibrosa is an increase of bone destruction(osteoclastic bone resorption). In addition, the bone marrow may also be found associated with bone marrow fibrosis which causes anemia and did not respond to erythropoietin.
