Objective: To compare biochemical parameters serum tumour necrosis factor alpha, calcium, magnesium, bone-specific alkaline phosphatase and vitamin D in postmenopausal women.
Methods: This cross-sectional study was carried out from June 2015 to July 2016 at Jinnah Medical and Dental College, Karachi, and comprised postmenopausal women. Bone mineral density done by dual energy X-ray absorptiometryscan categorised subjects by World Health Organisation classification into normal (T score > -1) osteopenic (T score between -1 and -2.5) and osteoporotic (T score < -2.5). Biochemical parameters like tumour necrosis alpha, calcium, magnesium, bone-specific alkaline phosphatase and vitamin D were measured by solid phase enzyme amplified sensitivity immunoassay method. SPSS 16 was used to analyse the data.
Results: Of the 146 women, 34(23%) were normal, 93(67%) were osteopenic and 19(13%) were osteoporotic. There was significant difference in mean body mass index, serum tumour necrosis factor alpha and calcium in all the three groups (p<0.01). Significant mean difference was observed in serum calcium levels between normal and osteopenic, and between normal and osteoporotic group (p<0.05 each) without any significant mean difference between osteopenic and osteoporotic groups (p>0.05). A significant difference was observed for mean tumour necrosis factor alpha values between normal and osteoporotic groups (p<0.05). Tumour necrosis factor alpha showed negative correlation with bone mineral density in osteopenic and osteoporotic groups (p>0.05).
Conclusions: Increased bone turnover in postmenopausal osteopenic women can be predicted by increased serum cytokine.
