A retrospective review was conducted on serum vitamin B12 levels in an HIV-infected outpatient cohort, many of whom received antiretroviral therapy. B12 levels were obtained at most staging visits (every six months) and when clinically indicated. For each serum B12 level, laboratory values and clinical symptoms were recorded. Thirty-two patients (32/251 or 13%) had at least one low B12 level (<211pg/mL) during the course of their HIV infection. Within two years of their initial HIV presentation, 6/57 patients had a low serum B12. Using multiple linear regression analysis, a higher serum B12 level was significantly associated with higher folate levels, African-American race, and lower mean corpuscular volume. B12 levels increased significantly after initiating antiretroviral therapy (416 vs 535 pg/mL, P=0.04). In conclusion, low serum B12 levels occur commonly among HIV-infected patients, even at early stages without overt symptoms of B12 deficiency. Antiretroviral therapy may increase serum B12 levels.
Purpose: This study assessed military healthcare providers' knowledge, clinical practice, and comfort in caring for active duty (AD) lesbian, gay, and bisexual (LGB) patients.Methods: Primary care providers at Fort Bragg, North Carolina were surveyed anonymously.Results: The response rate was 28% (n = 40). Almost two-thirds of the respondents felt comfortable discussing sexual health with AD patients, but only 5% inquired about same-sex sexual activity. Slightly less than one-third reported prior training in LGB healthcare topics and nearly four-fifths desired clear guidance from the Department of Defense regarding the process for screening and documentation of AD same-sex sexual activity.Conclusion: The findings highlight providers' need and desire for training in LGB patient care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
