Use of vitamin Ds to treat kidney disease

Disclosed are compositions containing a VDRA / Vitamin D analog to treat or prevent kidney disease, including chronic kidney disease. The present invention also relates to methods of treating kidney disease by administering to a patient a pharmaceutical composition containing a therapeutically effective amount of a VDRA / Vitamin D analog. Compositions according to the invention include a VDRA / Vitamin D analog and at least one of the following agents: an ACE inhibitor, an angiotensin (II) receptor blocker (ARB) and aldosterone blocker in therapeutically effective amounts to inhibit renin production or inhibit activation of the renin-angiotensin-aldosterone system. Preferred compositions contain paricalcitol with at least one of these other agents. Such combinations can avoid ACE inhibition escape and aldosterone escape with subsequent increase in angiotensin (II) and aldosterone generation.

Methods for reducing body fat using vitamin D compounds

A treatment for obesity and overweight comprises administering a vitamin D analog. The analog effectively inhibits an increase in body fat to animals at risk and decreases the basal fat content of animals. The treatment has a positive effect on the lean body component such that while there is an overall decrease in body weight, there is also a decrease in percent body fat. This decrease can be proportionally greater than the overall decrease in body weight. In addition, the treatment has a positive effect on bone turnover and osteogenesis making the vitamin D analog a beneficial treatment for the symptoms of menopause. Various exemplary embodiments of the treatment use the 2-alkylidene derivatives of vitamin D3, such as the 2-alkylidene-19-nor derivatives in both the R and S configurations at carbon-20.
