BACKGROUND In the United States, anal cancer in men who have sex with men (MSM) is more common than cervical cancer in women. Human papillomavirus (HPV) is causally linked to the development of anal and cervical cancer. In women, cervical HPV infection peaks early and decreases after the age of 30. Little is known about the age-specific prevalence of anal(More)
BACKGROUND Infection with human papillomavirus (HPV) is causally linked to the development of anal and cervical cancer. In the United States, the incidence of anal cancer among men who have sex with men (MSM) is higher than the incidence of cervical cancer among women. Anal squamous intraepithelial lesions (ASILs) are anal cancer precursors comprising(More)
OBJECTIVE Human papillomavirus (HPV) is a common sexually transmitted agent that causes anogenital cancer and precancer lesions that have an inflammatory infiltrate, may be friable and bleed. Our aim was to determine the association between anal HPV infection and HIV acquisition. DESIGN A prospective cohort study. METHODS We recruited 1409 HIV-negative(More)
We describe 3 patients who developed atypical manifestations of Mycobacterium avium complex (MAC) infection >10 months (range, 3-16 months) after attaining sustained CD4(+) T cell counts of >100 cells/microL while receiving antiretroviral therapy and not receiving MAC prophylaxis. The common features of these cases include the degree of immune(More)
Before the introduction of highly active antiretroviral therapy (HAART), several studies demonstrated a high prevalence of human papillomavirus (HPV) infection and associated anal intraepithelial neoplasia (AIN) in men who have sex with men, particularly in human immunodeficiency virus (HIV)-infected men with low CD4+ cell counts. Similarly high levels of(More)
Human papillomavirus (HPV) is one of the most common sexually transmitted infections and a significant cause of anogenital malignancies, precancer lesions, and cutaneous disease. Human immunodeficiency virus (HIV)-positive individuals have a higher prevalence of HPV infection and HPV-associated anogenital disease compared to age-matched HIV-negative(More)
BACKGROUND The substantial frequency of drug resistance in persons recently infected with HIV implies exposure among HIV-uninfected individuals to HIV-infected persons with drug-resistant virus. Although there is an increasing emphasis on understanding high-risk behavior among HIV-infected patients, little work has focused on those with drug-resistant(More)
We report the first described case of Arthrographis kalrae pansinusitis and meningitis in a patient with AIDS. The patient was initially diagnosed with Arthrographis kalrae pansinusitis by endoscopic biopsy and culture. The patient was treated with itraconazole for approximately 5 months and then died secondary to Pneumocytis carinii pneumonia. Postmortem(More)
The incidence of human papillomavirus (HPV)-associated epithelial lesions is substantially higher in human immunodeficiency virus (HIV)-infected individuals than in HIV-uninfected individuals. The molecular mechanisms underlying the increased risk of HPV infection in HIV-infected individuals are poorly understood. We found that HIV proteins tat and gp120(More)
Optimal clinical care and clinical investigation of patients with mucormycosis are limited by absence of controlled trials, and absence of well-defined predictors of mortality or clinical response. The Deferasirox-AmBisome Therapy for mucormycosis (DEFEAT Mucor) study was the first randomized clinical trial conducted on patients with mucormycosis, and(More)
