Prevalence and Risk Factors of Low Bone Mineral Density in Korean HIV-Infected Patients: Impact of Abacavir and Zidovudine
نویسندگان
چکیده
Low bone mineral density (BMD) is common in HIV-infected patients. We aimed to describe the prevalence of low BMD and risk factors in Korean HIV-infected patients and to assess the effects of antiretroviral therapy (ART) on BMD. We retrospectively evaluated 224 HIV infected-patients. The prevalence of osteopenia and osteoporosis were 41.5% and 12.9%. These were much higher in 53 patients aged 50 yr and older (52.8% and 34.0%). Older age, lower body mass index, and ART > 3 months were independent risk factors for low BMD. Osteoporosis was more prevalent in patients on the abacavir-based regimen for < 1 yr than ≥ 1 yr; however, it was more prevalent in patients on the zidovudine-based regimen for ≥ 1 yr than < 1 yr (P = 0.017). Osteoporosis in patients on the abacavir-based regimen was more common in the spine than in the femur (P = 0.01). Given such a high prevalence of low BMD, close monitoring of BMD for HIV-infected patients on ART is required. The different prevalence of osteoporosis over time and affected areas between two regimens suggest they may play roles in different mechanisms in bone loss.

متن کاملEvaluation of Frequency Pattern of Risk Factors for Decreased Bone Mineral Density in Postmenopausal Women Referred to the Bone Mineral Density Assessment Center of Al-Zahra Hospital in Isfahan during Years 2018 and 2019
Introduction: Osteoporosis is a systemic skeletal disease in which the internal structure and ability of bone to repair its daily damage is impaired. Menopause is a vital period that affects bone health, causing rapid loss of bone mass, which in turn increases the risk of fractures in postmenopausal women. The present study was performed to evaluate the frequency pattern of risk factors for dec...
متن کاملImprovement in bone mineral density after switching from tenofovir to abacavir in HIV-1-infected patients with low bone mineral density: two-centre randomized pilot study (OsteoTDF study).
BACKGROUND Tenofovir has been associated with a decrease in bone mineral density (BMD). However, data on changes in BMD after discontinuing tenofovir are lacking. METHODS We performed a two-centre randomized pilot study in virologically suppressed HIV-infected patients receiving tenofovir with osteopenia/osteoporosis (OsteoTDF study, ClinicalTrials.gov number NCT 01153217). Fifty-four patient...
