Patients with mild to moderate essential hypertension on medication were allowed if their blood pressure was controlled within the normal range for at least one month. Positive rapid test for HIV antibody. All subjects were tested for HIV antibody using a rapid serologic test at the time of enrollment beginning with protocol version 1.7. Prior to that only subjects who had a history of a negative screening test for HIV during their most recent pregnancy were included. Subjects given HIV rapid serologic tests in this study were provided pre-test counseling before the test was performed and post-test counseling when the subject was informed of the test results. This counseling is provided by the study nurses according to CDC guidelines [Centers for Disease Control and Prevention. Revised Guidelines for HIV Counseling, Testing and Referral and Revised Recommendations for HIV Screening of Pregnant Women.
