title: Continuation of postpartum antiretroviral therapy in a cohort of women infected with human immunodeficiency virus.
abstract: A common dilemma for HIV-positive pregnant women is the issue of continuation or cessation of antiretroviral therapy (ART) postpartum. Current guidelines for ART during pregnancy offer no specific recommendations for postpartum ART care. The objective of this study was to ascertain characteristics that would predict cessation or continuation of ART postpartum. In this study, prenatal and medical clinic records were reviewed retrospectively for a cohort of 29 HIV-infected pregnant women who were seen in the Temple University High Risk obstetrics practice from 1997 to 1998. All women took ART during pregnancy, except for one who received i.v. AZT and nevirapine during labor. HIV-specific medical care was provided concurrently during the time of the woman's obstetrics visit by a nurse practitioner and a clinical nurse specialist in consultation with the physician. Factors that were included for review included race, age, use of ART at the time of pregnancy diagnosis, type of ART during pregnancy, CD4 count, HIV-1 ribonucleic acid polymerase chain reaction (RNA PCR) levels, current substance use, disclosure of HIV status to current partner, years of HIV infection, prior HIV infected child, and whether this was a first pregnancy. The two groups of women were divided between those who discontinued ART postpartum and those who continued ART. The data were analyzed with the Kruskal-Wallis test for two groups, or calculations of risk ratios with Fisher's exact test. Study results indicated that 15 out of 29 women (51%) continued ART postpartum. The significant factors for continuation included Latina ethnicity (risk ratio = 0.24, confidence interval = 0.06-0.87), CD4 < 200 mm3 (p = .04), and a greater number of drugs in the antiretroviral regimen 3 versus 2 (p = .05). This study showed that postpartum continuation of ART was associated with identified Latina ethnicity, lower CD4 counts, and a greater number of drugs in the pregnancy regimen. Further study is recommended to understand the clinical impact of intermittent ART, the strategies for postpartum therapy adherence, and clinical follow-up.
