Comparing FRAX and Garvan Fracture Risk Calculator in postmenopausal women: A prospective 5-year follow-up study
2011
Introduction.We explored the prevalence of vitamin D deficiency and secondary hyperparathyroidism(sHPTH) ina case–control studyof100HIV-infectedpatients (HIV) and100 matched controls.Methods. HIVwere included if theywere naive to antiretroviral therapy (ART) or receiving first line ART. Healthy controls were matched for age (age range 25–65 years) and gender. Subjects, recruited between February–April 2009, underwent a standardized assessment to evaluate demographic and anthropometric characteristics, bone mineral density (BMD), serum calcium, phosphate, 25-hydroxy-vitamin D (25OHD), PTH, markers of bone turnover, clinical history and ART regimens (HIV only). The proportion of patientswith 25OHD 65 pg/ml was calculated. Secondary analyses were undertaken to evaluate variables associated with vitamin D deficiency in HIV. Results. The two groups were comparable with regard to baseline characteristics, except for alcohol intake, level of physical activity and prevalence of fractures. A significantly greater proportion (p =20), reclassification analyses showed that the GFRC reclassified more patients who sustaineda fracture to higher risk categories (85.4%), but alsomorepatientswhodidnot sustain a fracture (68.7%). Therefore, net reclassification was not significant (p>0.05, Table 1). Even after correction of the 10-year risk of FRAX (1/(major fractures/all fractures)=1/(36/ 48)=1.33) the results remained the same, and also when BMD was not included (data not shown). Discussion: GFRC, compared with FRAX, resulted in significantly higher fracture risks for women who did and did not sustain a fracture after baseline. GFRC reclassified significantly more women who did sustain a fracture to higher risk categories. However, the net reclassification was not significant.
