          Abstract

          Objectives

          To identify the approaches that are used in improving on male partner involvement in the prevention of mother-to-child transmission (PMTCT) of HIV and their impact on the uptake maternal antiretroviral therapy (ART) in sub-Saharan Africa (SSA).

          Setting

          This was a systematic review and meta-analysis of published studies carried out in SSA at all levels of healthcare (primary, secondary, tertiary and community).

          Participants

          The participants of the studies included were HIV-positive pregnant women and breastfeeding mothers with their male partners. Studies were included if they were conducted in SSA and mentioned an approach used in improving male partner involvement with data on the impact on the uptake of maternal ART uptake.

          Outcomes

          In the protocol, maternal ART uptake, infant prophylaxis, safe infant feeding options, condom use and family planning were envisaged. However, only maternal ART has been reported here due to limitations on the word count.

          Results

          From an initial 2316 non-duplicate articles, 17 articles were included in the systematic review and meta-analysis. In the combined model, the ORs for complex community interventions, enhanced psychosocial interventions, verbal encouragement and invitation letters were 4.22 (95% CI 2.27 to 7.77), 2.29 (95% CI 1.42 to 7.69), 2.39 (95% CI 1.26 to 4.53) and 1.21 (95% CI 0.89 to 1.63), respectively, whereas in the model using adjusted ORs, enhanced psychosocial interventions had a higher effect than any other intervention. The heterogeneity was moderate using adjusted ORs.

          Conclusion

          Enhanced psychosocial interventions and complex community interventions increase male partner involvement and the uptake of PMTCT services more than any other intervention. Invitation letters had no effect. More randomised trials and observational studies (that have adjusted for potential confounders) are needed in the future.

          Antenatal couple counseling increases uptake of interventions to prevent HIV-1 transmission.

          To determine effect of partner involvement and couple counseling on uptake of interventions to prevent HIV-1 transmission, women attending a Nairobi antenatal clinic were encouraged to return with partners for voluntary HIV-1 counseling and testing (VCT) and offered individual or couple posttest counseling. Nevirapine was provided to HIV-1-seropositive women and condoms distributed to all participants. Among 2104 women accepting testing, 308 (15%) had partners participate in VCT, of whom 116 (38%) were couple counseled. Thirty-two (10%) of 314 HIV-1-seropositive women came with partners for VCT; these women were 3-fold more likely to return for nevirapine (P = 0.02) and to report administering nevirapine at delivery (P = 0.009). Nevirapine use was reported by 88% of HIV-infected women who were couple counseled, 67% whose partners came but were not couple counseled, and 45%whose partners did not present for VCT (P for trend = 0.006). HIV-1-seropositive women receiving couple counseling were 5-fold more likely to avoid breast-feeding (P = 0.03) compared with those counseled individually. Partner notification of HIV-1-positive results was reported by 138 women (64%) and was associated with 4-fold greater likelihood of condom use (P = 0.004). Partner participation in VCT and couple counseling increased uptake of nevirapine and formula feeding. Antenatal couple counseling may be a useful strategy to promote HIV-1 prevention interventions.

            Assessing the quality of randomized trials: reliability of the Jadad scale.

            An instrument was developed and validated by Jadad, et al. to assess the quality of clinical trials using studies from the pain literature. Our study determined the reliability of the Jadad scale and the effect of blinding on interrater agreement in another group of primary studies. Four raters independently assessed blinded and unblinded versions of 76 randomized trials. Interrater agreement was calculated among combinations of four raters for blinded and unblinded versions of the studies. A 4 x 2 x 2 repeated measures design was employed to evaluate the effect of blinding. The interrater agreement for the Jadad scale was poor (kappa 0.37 to 0.39), but agreement improved substantially (kappa 0.53 to 0.59) with removal of the third item (an explanation of withdrawals). Blinding did not significantly affect the Jadad scale scores. A more precise description of how to score the withdrawal item and careful conduct of a practice set of articles might improve interrater agreement. In contrast with the conclusions reached by Jadad, we were unable to demonstrate a significant effect of blinding on the quality scores.

              Triple antiretroviral compared with zidovudine and single-dose nevirapine prophylaxis during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV-1 (Kesho Bora study): a randomised controlled trial.

              Breastfeeding is essential for child health and development in low-resource settings but carries a significant risk of transmission of HIV-1, especially in late stages of maternal disease. We aimed to assess the efficacy and safety of triple antiretroviral compared with zidovudine and single-dose nevirapine prophylaxis in pregnant women infected with HIV. Pregnant women with WHO stage 1, 2, or 3 HIV-1 infection who had CD4 cell counts of 200-500 cells per μL were enrolled at five study sites in Burkina Faso, Kenya, and South Africa to start study treatment at 28-36 weeks' gestation. Women were randomly assigned (1:1) by a computer generated random sequence to either triple antiretroviral prophylaxis (a combination of 300 mg zidovudine, 150 mg lamivudine, and 400 mg lopinavir plus 100 mg ritonavir twice daily until cessation of breastfeeding to a maximum of 6·5 months post partum) or zidovudine and single-dose nevirapine (300 mg zidovudine twice daily until delivery and a dose of 600 mg zidovudine plus 200 mg nevirapine at the onset of labour and, after a protocol amendment in December, 2006, 1 week post-partum zidovudine 300 mg twice daily and lamivudine 150 mg twice daily). All infants received a 0·6 mL dose of nevirapine at birth and, from December, 2006, 4 mg/kg twice daily of zidovudine for 1 week after birth. Patients and investigators were not masked to treatment. The primary endpoints were HIV-free infant survival at 6 weeks and 12 months; HIV-free survival at 12 months in infants who were ever breastfed; AIDS-free survival in mothers at 18 months; and serious adverse events in mothers and babies. Analysis was by intention to treat. This trial is registered with Current Controlled Trials, ISRCTN71468401. From June, 2005, to August, 2008, 882 women were enrolled, 824 of whom were randomised and gave birth to 805 singleton or first, liveborn infants. The cumulative rate of HIV transmission at 6 weeks was 3·3% (95% CI 1·9-5·6%) in the triple antiretroviral group compared with 5·0% (3·3-7·7%) in the zidovudine and single-dose nevirapine group, and at 12 months was 5·4% (3·6-8·1%) in the triple antiretroviral group compared with 9·5% (7·0-12·9%) in the zidovudine and single-dose nevirapine group (p=0·029). The cumulative rate of HIV transmission or death at 12 months was 10·2% (95% CI 7·6-13·6%) in the triple antiretroviral group compared with 16·0% (12·7-20·0%) in the zidovudine and single-dose nevirapine group (p=0·017). In infants whose mothers declared they intended to breastfeed, the cumulative rate of HIV transmission at 12 months was 5·6% (95% CI 3·4-8·9%) in the triple antiretroviral group compared with 10·7% (7·6-14·8%) in the zidovudine and single-dose nevirapine group (p=0·02). AIDS-free survival in mothers at 18 months will be reported in a different publication. The incidence of laboratory and clinical serious adverse events in both mothers and their babies was similar between groups. Triple antiretroviral prophylaxis during pregnancy and breastfeeding is safe and reduces the risk of HIV transmission to infants. Revised WHO guidelines now recommend antiretroviral prophylaxis (either to the mother or to the baby) during breastfeeding if the mother is not already receiving antiretroviral treatment for her own health.
