Filter by:The purpose of this study is to obtain data on the safety and effectiveness of Zemplar® (paricalcitol) injection and paricalcitol capsules in real-life clinical practice. Participants, who have been treated with paricalcitol in-label in an everyday setting, have been included into this study. A period of 12 months has been chosen in order to also obtain experience on the maintenance dose and treatment optimization with paricalcitol injection and paricalcitol capsules in long-term use.
The purpose of this study is to obtain data on the use of Zemplar (paricalcitol) capsules in real-life clinical practice in predialysis patients with chronic kidney disease (CKD) and secondary hyperparathyroidism.
The aim of this post-marketing observational study is to obtain further data on the long term use, safety and efficacy of Zemplar as it is prescribed in the normal clinical setting and according to the approved Summary of Product Characteristics for the treatment of secondary hyperparathyroidism in hemodialysis patients in Greece.
The purpose of this study was to ascertain the percentage of cardiac patients with chronic kidney disease (CKD) stage 5 treated with paricalcitol IV achieving intact parathyroid hormone (iPTH) levels in target range of Kidney Disease Outcomes Quality Initiative (K/DOQI) treatment guidelines (150 - 300 pg/mL) after 2 years.
Because of its high sun exposure, Israel was traditionally supposed to be protected from vitamin D deficiency, and the country food products hardly contain vitamin D supplements. However the Jerusalem ultra-Orthodox population, which constitutes a significant fraction of the city population, is at risk of developing vitamin D deficiency due to low sun exposure, as consequence of its dressing code covering most of the body and very limited time of outside activities. The investigators aim is to check whether vitamin D deficiency is found more frequently in the ultra-Orthodox male population in comparison to a non-ultra-Orthodox male population, and to study its eventual consequences. Correlation between vitamin D levels and PTH levels will be examined, according to age and to creatinine levels. Bone mineral density (BMD) will be evaluated in 2 selected subgroups of subjects (with lowest and highest vitamin D levels), and re-evaluated after 6 months of vitamin D supplementation in vitamin D-deficient subjects. An increase in BMD within 6 months would suggest osteomalacia as the main cause of low BMD in these subjects.
The purpose of this study is to determine if vitamin D supplementation changes the results of certain tests associated with inflammation in the body using an oral, synthetic form of vitamin D called paricalcitol.
FGF-23 is a newly described protein that is an important regulator of phosphorus in the body. This protein increases in people with kidney disease and people who need dialysis have very high levels of FGF-23 in the blood. However, although some studies have indicated that FGF-23 levels go up with increased intake of phosphorus, no one knows if FGF-23 levels can be lowered in patients with kidney disease by preventing them from absorbing phosphorus from food. This study is designed to see what happens to levels of FGF-23 in the blood when patients with chronic kidney disease take medications to prevent phosphorus absorption. Since high levels of FGF-23 have been linked with increased rates of death in patients with advanced kidney disease, controlling the levels may, in the future, be a way to decrease heart disease in patients with kidney disease.
This study is a exploratory comparison of the efficacy and safety of paricalcitol injection with maxacalcitol injection in chronic kidney disease participants receiving hemodialysis with secondary hyperparathyroidism.
Evaluates the effectiveness of on-label Paricalcitol versus Cinacalcet with Low-Dose Vitamin D.
This is an open label, single center, randomized, active comparator controlled study, comparing the effects of vitamin D replacement using oral ergocalciferol versus paricalcitol on parathyroid hormone (PTH) levels in patients with stage 3 and 4 CKD and vitamin D deficiency or insufficiency. The purpose of this study is to determine which of these two approaches is more successful.
