  • Title: Use of dual-energy x-ray absorptiometry (DXA) scans in HIV-infected patients.
    Author: Dickinson SA, Fantry LE.
    Journal: J Int Assoc Physicians AIDS Care (Chic); 2012; 11(4):239-44. PubMed ID: 22511611.
    Abstract:
    Multiple studies have demonstrated increased rates of osteopenia and osteoporosis in HIV-infected patients but there have been no published studies on current screening practices. We conducted a retrospective chart review of 2924 patients attending an urban HIV clinic. Thirty patients (1%) had dual-energy x-ray absorptiometry (DXA) scans. Patients undergoing DXA scans were more likely to be older, women, and have nondetectable HIV viral load and CD4 count ≥200. The most frequently cited indications for screening were perimenopausal or postmenopausal status and HIV infection. Of the patients screened, 96% had osteopenia or osteoporosis with a median T-score of -1.9 and a median of 3.8 osteoporosis risk factors in addition to HIV.  Of the 20 practitioners in the clinic, only 7 had patients with screening DXA scans. DXA scans are underutilized in the HIV population given the high rate of osteopenia and osteoporosis detected in this study.
