Definitions

  • osteopenia With age the equilibrium between bone mass resorption and formation becomes altered, generally in favour of resorption, resulting in a reduction of bone mass termed osteopenia. This age related loss of equilibrium is generally due to both a decline in bone formation and more resorption. It is caused by the decrease in estrogen production in post-menopausal women, and the decline with age in the production of androgen in men (which is enzymatically converted to estrogen, a hormone that regulates bone metabolism directly and indirectly). Eventually this may lead to deterioration of bone architecture, decreased resistance to stress, bone fragility and susceptibility to fractures. These symptoms are collectively referred to as osteoporosis, which is a major health problem, especially in Western society, where it has been estimated that up to 85% of women and somewhat fewer men older than 45 years of age are at risk of developing osteoporosis.
  • osteoporosis may be caused by a high fat diet upregulating adipocyte differentiation at the cost of osteoblast differentiation.
  • This hypotheses was later substantiated by findings such as that oxidized lipids inhibit differentiation of preosteoblasts, and that minimally oxidized LDL act to inhibit osteogenic differentiation through activating PPAR alpha (Parhami F et al, J Bone Miner Res, 1999 December; 14(12):2067-78), and that PPAR gamma seems to be responsible for the decrease in osteoblasts and increase in marrow fat seen in the elderly due to its inhibition of osteoblastogenesis and stimulation of adipocyte differentiation (Ali A A et al, Endocrinology.
  • a PPAR gamma activator was found to inhibit stimulators of osteoclastogenesis in one publication, indirectly suggesting that PPAR gamma may decrease bone resorption (Mbalaviele G, et al, J Biol. Chem. 2000 May 12; 275(19):14388-93), but a more recent publication found direct evidence of the opposite; a PPAR gamma agonist enhanced bone loss, increased fat marrow volume, and increased bone resorption parameters (Sottile V et al Calcif Tissue Int. 2004 October; 75(4):329-37. Epub 2004 Jul. 13).
  • PPAR alpha and delta in regards to bone resorption, and the little information there is about PPAR gamma is conflicting, although the most direct evidence point towards a role for PPAR gamma in increasing resorption.
  • the compounds according to the invention are analogues of naturally occurring compounds, and as such are recognized by the same systems which process the natural compounds, including the enzymes that ⁇ - and in some cases ⁇ -oxidize natural long chain fatty acids.
  • the analogues differ from their naturally occurring counterparts in that they cannot be completely oxidized in this manner.
  • the compounds of the present invention may be administered directly to the animal by any suitable technique, including parenterally, intranasally, orally, or by absorption through the skin. They can be administered locally or systemically.
  • the specific route of administration of each agent will depend, e.g., on the medical history of the recipient human or animal.
  • Bone metabolism parameters comprise markers present in the blood such as BAP (a marker of osteogenesis), DPD (a bone resorption marker), NTX, corrected Ca, and the SOS value (an index of bone metabolism impairment).
  • Crosslaps has also been used to predict the rate of bone loss considering a bone loss of more than 3% per year.
  • Crosslapse has a specificity of 80% and a sensitivity of more than 70%, it can thus be used as a potentially useful screening parameter in the risk assessment of diseases like postmenopausal osteoporosis and Paget's disease.
  • Crosslaps values decreases substantially in response to replacement therapies thus suggesting its usefulness in monitoring treatment efficacy.
  • Crosslaps have been cleared by the FDA, and is currently used for research only, but is expected to be available for general testing soon. It is developed by Nordic bioscience diagnostics.
