Meningococcal Conjugate and Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccination Among HIV-infected Youth.

Background: The meningococcal conjugate vaccine (MCV4) and the tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine (Tdap) were first recommended for adolescents in the US in 2005. The goal of our study was to determine MCV4 and Tdap vaccines coverage among perinatally and behaviorally HIV-infected adolescents in 2006 and to compare coverage estimates in our study population to similarly aged healthy youth in 2006.

Methods: Longitudinal Epidemiologic Study to Gain Insight into HIV/AIDS in Children and Youth (LEGACY) is a retrospective cohort study of HIV-infected youth in 22 HIV specialty clinics across the US.

Correlates of HIV testing refusal among emergency department patients in the opt-out testing era.

Opt-out HIV screening is recommended by the CDC for patients in all healthcare settings. We examined correlates of HIV testing refusal among urban emergency department (ED) patients. Confidential free HIV screening was offered to 32,633 ED patients in an urban tertiary care facility in Washington, DC, during May 2007-December 2011.

Correlates of sexual activity and sexually transmitted infections among human immunodeficiency virus-infected youth in the LEGACY cohort, United States, 2006.

Background: To determine the prevalence and correlates of sexual activity and sexually transmitted infections (STIs) among human immunodeficiency virus (HIV)-infected youth.

Methods: The Longitudinal Epidemiologic Study to Gain Insight into HIV/AIDS in Children and Youth (LEGACY) is an observational medical record study of perinatally and behaviorally HIV-infected (PHIV and BHIV) youth followed at 22 US HIV clinics. PHIV youth were HIV infected at birth or by breast-feeding.

HIV-1 infection as a risk factor for incomplete childhood immunization in Zambia.

Immunizations are of particular importance for human immunodeficiency virus type 1(HIV-1)-infected children as they are at increased risk of severe disease and death from several vaccine-preventable diseases. Outside the United States, however, research on the impact of the HIV-1 epidemic on childhood immunization coverage is sparse. We conducted a nested case-control study in hospitalized children with measles to assess whether HIV-1 infection was a risk factor for incomplete immunization with diphtheria-tetanus-pertussis vaccine (DTP) and oral polio vaccine (OPV).
