Study of Perinatal Transmission of Zidovudine-Resistant HIV Among Pregnant Women Treated With Zidovudine - Full Text View

Sponsored by:	National Institute of Allergy and Infectious Diseases (NIAID)
Information provided by:	National Institute of Allergy and Infectious Diseases (NIAID)
ClinicalTrials.gov Identifier:	NCT00000828

Purpose

To identify patterns of zidovudine ( AZT ) susceptibility among mother/infant pairs with perinatal HIV transmission.

Most HIV-infected infants acquire their disease via perinatal transmission. Since transmission of HIV-resistant strains to infants could alter the course of disease and response to currently recommended treatment, a study to assess the patterns of AZT susceptibility among mother/infant pairs with perinatal transmission is essential to delineate future therapeutic strategies.

Detailed Description:

Most HIV-infected infants acquire their disease via perinatal transmission. Since transmission of HIV-resistant strains to infants could alter the course of disease and response to currently recommended treatment, a study to assess the patterns of AZT susceptibility among mother/infant pairs with perinatal transmission is essential to delineate future therapeutic strategies.

HIV-infected pregnant women are enrolled at 20-36 weeks gestation. Patients have blood drawn for HIV culture at study entry and at delivery. Infants have blood drawn for HIV culture at delivery and at 1, 3, 6, and 18 months of age.

Eligibility

Ages Eligible for Study:	13 Years to 60 Years
Genders Eligible for Study:	Female
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria

Patients must have:

HIV seropositivity.
CD4 count <= 300 cells/mm3.
Gestational age of 20-36 weeks, with intention to carry pregnancy to term.
At least 6 months of prior AZT therapy, including continuous AZT therapy during the current pregnancy.

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

Evidence of pre-existing fetal anomalies that would preclude survival to the end of the study, such as anencephaly, renal agenesis, or Potter's syndrome.

Concurrent Medication:

Excluded:

Antiretrovirals other than AZT.
