Key clinical point: There was an increase in levels of cathepsin Z mRNA in peripheral blood mononuclear cells in participants with osteopenia and osteoporosis, compared with nonosteoporotic controls.
Major finding: Cathepsin Z was inversely associated with bone mineral density and inversely associated with lumbar spine L2-L4 and femoral neck T scores in participants with osteopenia, osteoporosis, and women with osteoporosis who were older than 50 years.
Study details: An analysis of cathepsin Z mRNA levels in PBMC samples from 88 participants with osteopenia, osteoporosis, and no osteoporosis.
Disclosures: The authors reported no relevant conflicts of interest.
