The aim of this post-marketing observational study is to obtain further data on the long term use, safety and efficacy of selective Vitamin D Receptor Activator's 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 Turkey. The relation of the safety data to PTH (Parathyroid hormone) suppression over time will be evaluated. Also the number and incidence of hypercalcemia and hyperphosphatemia will be recorded.

The scientific purpose of this study is to obtain data on the use of sVDRA(Selective Vitamin D Receptor Activator) in real-life clinical practice. This study will allow us to observe drug effectiveness in a distinct geography. Treatment effects, as well as maintenance of the results will be recorded for a 18 months period in order to obtain experience in the long term use of sVDRA(Selective Vitamin D Receptor Activator). Furthermore in the centers, additional blood parameter, hsCRP (high sensitivity C-reactive protein), will be examined as part of the clinical routine.

The primary aim of the study is:

* To assess percentage change in iPTH (intact parathyroid hormone) level monthly among hemodialysis patients with sHPT (secondary hyperparathyroidism) receiving sVDRA (Selective Vitamin D Receptor Activator) therapy.

Secondary aims are:

* To observe changes in commonly assessed biochemical parameters for bone and mineral metabolism (Ca (Calcium), P (Phosphorus), ALP (Alkaline phosphatase) and additionally hsCRP (high sensitivity C-reactive protein) as cardiovascular inflammatory marker.
* To evaluate routinely checked parameters like albumin, hemoglobin and dialysis adequacy (KT/V).
* To collect and evaluate data from all adverse events in order to establish the safety profile of sVDRA(Selective Vitamin D Receptor Activator) in daily clinical practice.
* To collect mortality data 6 months after 12 months of observational period or 6 months after drop out.

Patients will be followed for 12 months within the post-marketing observational study and will be checked for mortality data 6 months after this follow up period. The enrollment period should not exceed 6 months.

All demographic information will be summarized by using descriptive statistics and graphs. Laboratory levels will be assessed by using mean, median, minimum, maximum, standard deviation and percentages on visit basis. The mean differences on laboratory levels between visits will also be summarized by graphics and assessed by using percentages.

Alkaline phosphatase and hsCRP (high sensitivity C-reactive protein) levels will also be summarized by using descriptive statistics and graphs per visit.

sVDRA (Selective Vitamin D Receptor Activator) dose changes per visits will be summarized by descriptive statistics and graphs.

Mortality will be analyzed with life tables. By taking into account the primary and secondary aims of the study, to be able to achieve the therapeutic success on iPTH (intact parathyroid hormone) level changes with sVDRA (Selective Vitamin D Receptor Activator) treatment and perform mortality assessment in following 6 months and collect data regarding safety and efficacy of sVDRAs (Selective Vitamin D Receptor Activators) in long term use, it has been determined to enroll totally 510 patients from 30 sites.
