Viral suppression and factors associated with failure to achieve viral suppression among pregnant women in South Africa.

ABSTRACT:

Objective

To describe viral load levels among pregnant women and factors associated with failure to achieve viral suppression (viral load ?50 copies/ml) during pregnancy.

Design

Between 1 October and 15 November 2017, a cross-sectional survey was conducted among 15-49-year-old pregnant women attending antenatal care (ANC) at 1595 nationally representative public facilities.

Methods

Blood specimens were taken from each pregnant woman and tested for HIV. Viral load testing was done on all HIV-positive specimens. Demographic and clinical data were extracted from medical records or self-reported. Survey logistic regression examined factors associated with failure to achieve viral suppression.

Result

Of 10?052 HIV-positive participants with viral load data, 56.2% were virally suppressed. Participants initiating antiretroviral therapy (ART) prior to pregnancy had higher viral suppression (71.0%) by their third trimester compared with participants initiating ART during pregnancy (59.3%). Booking for ANC during the third trimester vs. earlier: [adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI):1.4-2.3], low frequency of ANC visits (AOR for 2 ANC visits vs. ?4 ANC visits: 2.0, 95% CI:1.7-2.4), delayed initiation of ART (AOR for ART initiated at the second trimester vs. before pregnancy:2.2, 95% CI:1.8-2.7), and younger age (AOR for 15-24 vs. 35-49 years: 1.4, 95% CI:1.2-1.8) were associated with failure to achieve viral suppression during the third trimester.

Conclusion

Failure to achieve viral suppression was primarily associated with late ANC booking and late initiation of ART. Efforts to improve early ANC booking and early ART initiation in the general population would help improve viral suppression rates among pregnant women. In addition, the study found, despite initiating ART prior to pregnancy, more than one quarter of participants did not achieve viral suppression in their third trimester. This highlights the need to closely monitor viral load and strengthen counselling and support services for ART adherence.

Project description:Background The goal of antiretroviral therapy is to achieve sustained human immune deficiency virus (HIV) viral suppression. However, research on factors associated with viral load suppression among adolescents in low and middle-income countries is limited. The objectives of this study were to determine HIV viral suppression levels among adolescents in Kabale district and the associated clinical, adherence and psychosocial factors. Methods Cross-sectional and retrospective cohort study designs were used. Two hundred and forty-nine adolescents living with HIV that attended clinics between September and October 2019 at nine health facilities were interviewed and their medical records reviewed. A data abstraction tool was used to collect clinical data from adolescent’s clinical charts, face to face interviews were conducted using semi-structured questionnaire adopted from the HEADS tool and in-depth interviews conducted with ten key informants. Qualitative data was analyzed using thematic content analysis. Logistic regression was used to determine the magnitude by which clinical and psychosocial factors influence viral load suppression. Odds Ratios (ORs) were used for statistical associations at 95% confidence interval considering statistical significance for p-values less than 0.05. Qualitative data collected from Key informants to support our quantitative findings was analyzed using thematic content analysis. Results HIV viral suppression among (n = 249) adolescents was at 81%. Having no severe opportunistic infections was associated with viral load suppression among adolescent living with HIV (OR = 1.09; 95%CI [1.753–4.589]; p<0.001) as well as having no treatment interruptions (OR = 0.86; 95% CI [2.414–6.790]; p = 0.004). Belonging to a support group (OR = 1.01; 95% CI [1.53–4.88]; P = 0.020), having parents alive (OR = 2.04; 95% CI[1.02–4.12]; P = 0.047) and having meals in a day (OR = 5.68; C.I = 2.38–6.12, P = 0.010), were significantly associated to viral load suppression. The findings also indicated that long distances from health facilities, transport challenges and unprofessional conduct of health workers that make adolescent unwelcome at health facilities negatively affected viral suppression among adolescents. Conclusion The findings indicate that HIV viral suppression among adolescents on ART was at 81%. Kabale district was likely not to achieve the third 90 of the UNAIDS 90-90-90 global target for this population category. The findings further indicate that having no severe opportunistic infection and no treatment interruptions, good nutrition status, peer support and support from significant others, were highly associated with viral load suppression.

Project description:BACKGROUND:Maternal immunization is an effective strategy to protect pregnant women and their infants from vaccine-preventable diseases. Despite the recommendation of maternal influenza and more recently pertussis immunization in Australia, uptake of these vaccines has been suboptimal. A midwife delivered immunization program for pregnant women at the Women's and Children's Hospital in South Australia commenced in April 2015. Monitoring the uptake of the current funded vaccine programs for pregnant women is limited. The study aimed to estimate maternal vaccine uptake and assess factors associated with influenza and pertussis vaccine uptake among pregnant women. METHODS:This prospective study was undertaken between November 2014 and July 2016 at the Women's and Children's Hospital. Following consent, demographic details and vaccination history for South Australian pregnant women who attended the antenatal clinic were collected. A standardised self-reported survey was completed during pregnancy with a follow up telephone interview at 8-10 weeks post-delivery. RESULTS:205 women consented and completed the self-reported survey. Of the 180 pregnant women who completed the study, 76% and 81% received maternal influenza and pertussis vaccines respectively. The adjusted odds of women receiving maternal vaccines during pregnancy were significantly higher for women delivering after the implementation of the midwife delivered program compared with women who delivered babies prior to the program for both pertussis vaccination (AOR 21.17, 95% CI 6.14-72.95; p<0.001) and influenza vaccination (AOR 5.95, 95% CI 2.13-16.61, p<0.001). Women receiving a recommendation from a health care provider and first time mothers were significantly more likely to receive influenza vaccination during pregnancy. CONCLUSIONS:High uptake of influenza and pertussis vaccines during pregnancy can be attained with health care provider recommendation and inclusion of maternal immunization as part of standard antenatal care. A midwife delivered maternal immunization program is a promising approach to improve maternal vaccine uptake by pregnant women.

Project description:OBJECTIVE:To determine retention in care and virologic suppression among HIV-infected adolescents and young adults attending an adolescent-friendly clinic compared to those attending the standard pediatric clinic at the same site. DESIGN:Retrospective cohort analysis. SETTING:Government supported, hospital-based antiretroviral clinic in KwaZulu-Natal, South Africa. PARTICIPANTS:Two hundred forty-one perinatally HIV-infected adolescents and young adults aged 13 to 24 years attending an adolescent-friendly clinic or the standard pediatric clinic from April 2007 to November 2015. INTERVENTION:Attendance in an adolescent-friendly clinic compared to a standard pediatric clinic. OUTCOMES MEASURES:Retention in care defined as one clinic visit or pharmacy refill in the prior 6 months; HIV-1 viral suppression defined as < 400 copies/ml. RESULTS:Overall, among 241 adolescents and young adults, retention was 89% (214/241) and viral suppression was 81% (196/241). Retention was higher among those attending adolescent clinic (95%) versus standard pediatric clinic (85%; OR 3.7; 95% confidence interval (CI) 1.2-11.1; p = 0.018). Multivariable logistic regression adjusted for age at ART initiation, gender, pre-ART CD4 count, months on ART, and tuberculosis history indicated higher odds of retention in adolescents and young adults attending adolescent compared to standard clinic (AOR = 8.5; 95% CI 2.3-32.4; p = 0.002). Viral suppression was higher among adolescents and young adults attending adolescent (91%) versus standard pediatric clinic (80%; OR 2.5; 95% CI 1.1-5.8; p = 0.028). A similar multivariable logistic regression model indicated higher odds of viral suppression in adolescents and young adults attending adolescent versus standard pediatric clinic (AOR = 3.8; 95% CI 1.5-9.7; p = 0.005). CONCLUSION:Adolescents and young adults attending an adolescent-friendly clinic had higher retention in care and viral suppression compared to adolescents attending the standard pediatric clinic. Further studies are needed to prospectively assess the impact of adolescent-friendly services on these outcomes.
