Considerations for human papillomavirus (HPV) vaccination of mid-adult women in the United States.

In the United States, human papillomavirus (HPV) vaccination is recommended for 11 or 12 year old girls, with catch-up vaccination through age 26 years. Data are available for women over the age of 26 years on immunogenicity for both quadrivalent and bivalent HPV vaccines and on efficacy for the quadrivalent HPV vaccine. If HPV vaccines are licensed for use in women over 26 years of age (mid-adult women), recommendations for this age group will need to be considered.

Determinants of newly detected human papillomavirus infection in HIV-infected and HIV-uninfected injection drug using women.

Background: We sought to identify factors associated with newly detected human papillomavirus (HPV) infection in a high-risk cohort of injection drug using women in Baltimore, MD.

Methods: We studied 146 HIV-infected and 73 HIV-uninfected female participants in a 5-year prospective HIV natural history study. We examined the association of sexual and nonsexual risk factors and newly detected type-specific HPV infection as determined by consensus PCR between consecutive visits.

Prevalence of hepatitis C virus infection among injection drug users in the United States, 1994-2004.

Objective: To examine hepatitis C virus (HCV) seroprevalence among injection drug users in 4 US cities from 1994 through 2004.

Methods: Demographic characteristics, behaviors, and prevalence of HCV antibody among 5088 injection drug users aged 18-40 years from Baltimore, Maryland; Chicago, Illinois; Los Angeles, California; and New York, New York, enrolled in 3 related studies--Collaborative Injection Drug User Study (CIDUS) I (1994-1996), CIDUS II (1997-1999), and CIDUS III/Drug User Intervention Trial (2002-2004)--were compared using the chi(2) and Mantel-Haenszel tests of significance. Trends over time were assessed by logistic regression.

Factors and temporal trends associated with highly active antiretroviral therapy discontinuation in the Women's Interagency HIV Study.

We characterized factors and temporal trends associated with discontinuation of highly active antiretroviral therapy (HAART) among 936 HIV-infected women enrolled in the Women's Interagency HIV Study. A multivariate analysis of post-HAART initiation exposures found that high HIV RNA levels (relative hazard [RH] = 1.36, P < 0.

Effects of bacterial vaginosis and other genital infections on the natural history of human papillomavirus infection in HIV-1-infected and high-risk HIV-1-uninfected women.

Background: Whether the natural history of human papillomavirus (HPV) infection is affected by bacterial vaginosis (BV) or Trichomonas vaginalis (TV) infection has not been adequately investigated in prospective studies.

Methods: Human immunodeficiency virus 1 (HIV-1)-infected (n=1763) and high-risk HIV-1-uninfected (n=493) women were assessed semiannually for BV (by Nugent's criteria), TV infection (by wet mount), type-specific HPV (by polymerase chain reaction with MY09/MY11/HMB01 HPV primers), and squamous intraepithelial lesions (SIL) (by cytological examination). Sexual history was obtained from patient report at each visit.

Highly active antiretroviral therapy and cervical squamous intraepithelial lesions in human immunodeficiency virus-positive women.

Background: Women infected with human immunodeficiency virus (HIV) have an increased risk of persistent squamous intraepithelial lesions (SILs) of the cervix. We assessed the association between use of highly active antiretroviral therapy (HAART) and regression of SIL in HIV-infected women enrolled in the Women's Interagency HIV Study, a large, multicenter, prospective cohort study.

Methods: Of 2059 HIV-infected participants, 312 HIV-infected women had normal cervical cytology at baseline and were subsequently diagnosed during 7 years of follow-up with incident SIL.

Clinical course of recurrent respiratory papillomatosis in Danish children.

Objective: To evaluate the clinical course of juvenile-onset recurrent respiratory papillomatosis (RP) with respect to age, disease duration, and maternal condylomas.

Design: Inception cohort study.

Setting: All ear, nose, and throat departments in public Danish hospitals.

Serum immunoglobulin A response to human papillomavirus type 16 virus-like particles in human immunodeficiency virus (HIV)-positive and high-risk HIV-negative women.

Serum samples from 2008 human immunodeficiency virus (HIV)-positive and 551 HIV-negative women were tested for immunoglobulin A (IgA) to human papillomavirus (HPV) type 16 capsids. IgA seropositivity was lower than previously reported IgG seropositivity (7% vs. 51%), but, like IgG antibodies, HPV 16 IgA was associated with sexual behavior, cervicovaginal HPV 16 DNA, and cytological abnormalities.

When to initiate highly active antiretroviral therapy: a cohort approach.

The appropriate immunologic stage of human immunodeficiency virus infection at which to initiate highly active antiretroviral therapy (HAART) among asymptomatic persons is a core question. A cohort approach using longitudinal data from the US Multicenter AIDS Cohort Study was used to mimic a clinical trial to assess the risk of acquired immunodeficiency syndrome (AIDS) by timing of therapy. Three treatment groups were defined according to CD4(+) count (cells/microl) at HAART initiation between July 1995 and January 2000: <200 (deferral to <200, n = 127), 200-349 (deferral to 200-349, n = 130), and 350-499 (immediate treatment, n = 92).

Serum immunoglobulin G response to human papillomavirus type 16 virus-like particles in human immunodeficiency virus (HIV)-positive and risk-matched HIV-negative women.

Baseline serum samples from 2815 human immunodeficiency virus (HIV)-positive and 963 HIV-negative women enrolled in 2 cohort studies were tested for immunoglobulin G antibodies to human papillomavirus type 16 (HPV-16) capsids. HPV-16 seropositivity was associated with lifetime number of sex partners (P<.001) among both HIV-positive and HIV-negative women.

Lymphoid follicles are generated in high-grade cervical dysplasia and have differing characteristics depending on HIV status.

The exact role of the mucosal immune response in the pathogenesis of human papillomavirus (HPV)-related premalignant and malignant diseases of the genital tract is poorly understood. We used immunohistochemical analysis to characterize immune cells in normal cervix (N = 21), HIV-negative high-grade dysplasia (N = 21), and HIV-positive high-grade dysplasia (N = 30). Classical germinal centers were present in 4.
