Conclusions
The levels of BTM, D3, PTH differed significantly between groups. This study demonstrated that bone metabolism depended mainly on processes related with menopause state and changes in D3, PTH and cytokines levels.
Methods
One hundred and thirteen women were divided into four groups: group I (35 not menstruating 50 - 60 years old with osteoporosis), II (23 not menstruating 50 - 60 years old without osteoporosis), III (30 menstruating 40 - 49 years old with osteoporosis), IV (25 menstruating 40 - 49 years old without osteoporosis). The following parameters were measured: IL-1β, IL-6, TNF-α, hormone oestradiol (E2), PTH, FSH, TSH, calcium (Ca2+), phosphates (P), alkaline phosphatase (bALP), C-terminal telopeptide of type I collagen alpha 1 chain (α1CTX), osteocalcin (OC), BMD, IBM.
Objective
In postmenopausal period, changes in bone turnover markers (BTM), vitamin D3, cytokines and parathyroid hormone (PTH) are frequently observed. The study was to assess bone mineral density (BMD) and bone metabolism index (IBM) in the perimenopausal women. Design years: 2013-2014. Subjects and
Results
IBM and BMD were significantly lower in premenopausal than in postmenopausal women. The concentration of OC, CTX, 25OH D3 and PTH levels differed significantly between group I vs. II, group I vs. III and group II vs. IV. Conclusions: The levels of BTM, D3, PTH differed significantly between groups. This study demonstrated that bone metabolism depended mainly on processes related with menopause state and changes in D3, PTH and cytokines levels.
