- Title:
Studies of States with Resistance to Vitamin D and Parathyroid Hormone
- Number:
89-DK-0173
- Summary:
Patients with confirmed or suspected conditions with a resistance to vitamin D or parathyroid hormone (PTH) will be admitted for diagnosis and treatment, and inclusion in other studies pertaining to similar conditions.
This study will provide information about problems relating to calcium in the blood, urine, and bones. Patients in this study will undergo a general evaluation / check-up to give researchers an idea of each person's condition or disease. Patients will receive treatment based on their diagnosis and asked to provide specimen samples for further research studies.
