A successful pregnancy is characterised by an increase in Th2 cytokines and suppression of Th1 cytokine production. A Th1 to Th2 cytokine shift is also observed in the disease progression of HIV infection. Highly active antiretroviral therapy (HAART) suppresses HIV viremia, increases CD4+ cell counts and counteracts the Th1 to Th2 shift. We hypothesised that the increased risk of premature delivery reported in HIV-infected, HAART-treated pregnant women is mediated through changes in the cytokine environment in pregnancy. Here, we present results relating to levels of interleukin (IL)-2 (Th1) and IL-10 (Th2) in peripheral blood mononuclear cells (PBMCs) measured three times during pregnancy in 49 HIV-infected women. Slope values representing the trend of repeated cytokine (IL-2-PHA, IL-2-Env, IL-10-PHA and IL-10-Env) measurements within women during pregnancy were estimated and median values compared by prematurity and HAART use. Multiple regression adjusted for HAART and cytokine slope clarified the additional and independent effect of HAART on prematurity risk. Results showed favourable immunomodulation induced by HAART with increased IL-2 and decreased IL-10. HAART use and IL-10-Env slopes were not significantly associated with prematurity risk, but each unit increase in IL-2-PHA slope was associated with an 8% increased risk of premature delivery (AOR, 1.08; 95% CI, 1.0-1.17; p=0.005). HAART use in pregnancy provides significant benefits in delaying HIV disease progression and reducing the risk of mother-to-child-transmission, but may be counterproductive in terms of successful pregnancy outcome.

The social-structural challenges experienced by people living with HIV (PHA) have been shown to contribute to increased use of the emergency department (ED). This study identified factors associated with frequent and nonurgent ED use within a cohort of people accessing antiretroviral therapy (ART) in a Canadian setting. Interviewer-administered surveys collected socio-demographic information; clinical variables were obtained through linkages with the provincial drug treatment registry; and ED admission data were abstracted from the Department of Emergency Medicine database. Multivariate logistic regression was used to compute odds of frequent and nonurgent ED use. Unstable housing was independently associated with ED use (adjusted odds ratio [AOR] =1.94, 95% confidence interval [CI] 1.24-3.04]), having three or more ED visits within 6 months of the interview date [AOR: 2.03 (95% CI: 1.07-3.83)] and being triaged as nonurgent (AOR = 2.71, 95% CI: 1.19-6.17). Frequent and nonurgent use of the ED in this setting is associated with conditions requiring interventions at the social-structural level. Supportive housing may contribute to decreased health-care costs and improved health outcomes amongst marginalized PHA.
