Parasitic infections represent a significant health threat among recent immigrants in Chicago.

Parasitic infections are likely under-recognized among immigrant populations in the USA. We conducted a cross-sectional study to evaluate if such infections have health impacts among recent immigrants in Chicago and to identify predictive factors for parasitic infections. A total of 133 recent immigrants were enrolled, filling out a standardized medical questionnaire and providing blood and stool samples.

No association between antepartum serologic and genital tract evidence of herpes simplex virus-2 coinfection and perinatal HIV-1 transmission.

Objective: The purpose of this study was to assess the risk of perinatal HIV-1 transmission in women who are coinfected with herpes simplex virus-2 (HSV-2).

Study Design: We performed a nested case-control study of 26 women whose HIV-1 was transmitted to their infants and 52 control subjects whose HIV-1 was not transmitted. We assessed antepartum serologic evidence of HSV-2 by HSV-2 serostatus and genital tract evidence of HSV-2 by presence of HSV-2 DNA.

Hepatitis A 2004 vaccination in children: methods and findings of a survey in two states.

Background: Hepatitis A vaccine coverage estimates needed for surveillance and vaccine policy decisions are not readily available for children older than 35 months or for adolescents. This article reports methodology developed for obtaining such estimates by telephone survey with and without provider record verification.

Methods: A random-digit-dial telephone survey with provider verification was conducted in Arizona and Oregon in 2004-2005 to obtain coverage estimates for children aged 2.

Relationship of pregnancy to human papillomavirus among human immunodeficiency virus-infected women.

Objective: Because parity is a reported risk factor for cervical cancer, we sought to estimate the effects of pregnancy on the prevalence, incident detection, and copy number of human papillomavirus (HPV) among human immunodeficiency virus (HIV)-infected women, patients at high risk for cervical cancer.

Methods: Human immunodeficiency virus-infected women who had a pregnancy in the Women's Interagency HIV Study (n = 178) and the Women and Infants Transmission Study (n = 450) underwent serial type-specific HPV DNA testing using MY09/MY11 polymerase chain reaction. During pregnancy and during the prepregnancy and postpregnancy periods, we assessed HPV prevalence, incident detection, and HPV copy number (estimated using hybridization signal strength) of both oncogenic and nononcogenic HPV.

Changing trends in clinical AIDS presentations and survival among HIV-1-infected women.

Objectives: To profile trends of clinical AIDS-defining illness (ADI) among a cohort of human immunodeficiency virus (HIV)-infected women over a 12-year period.

Methods: In a prospective evaluation of AIDS clinical presentation in the Women and Infants Transmission Study (WITS), 2255 subjects were enrolled and followed between December 1989 and June 2002 (total, 4993 person-years). Data on clinical AIDS presentation of 140 (6.

The relationship of pregnancy to human immunodeficiency virus disease progression.

Objective: This study was undertaken to determine the effect of pregnancy on progression of human immunodeficiency virus (HIV) disease.

Study Design: We compared the immunologic, clinical, and virologic courses of 953 women who had no additional pregnancy after their index pregnancy, with the courses of 329 women who had a second pregnancy subsequent to their index pregnancy. Baseline variables included use of antiretroviral therapy, and CD4 and HIV RNA values.
