Factors Associated with Viral Suppression Among Adolescents on Antiretroviral Therapy in Homa Bay County, Kenya: A Retrospective Cross-Sectional Study

HIV viral suppression and risk of viral rebound in patients on antiretroviral therapy: a two- year retrospective cohort study in Northern Tanzania

BACKGROUND

The world is moving towards the third target of the Joint United Nations Programme on HIV/AIDS to ensure most people receiving antiretroviral therapy (ART) are virologically suppressed. Little is known about viral suppression at an undetectable level and the risk of viral rebound phenomenon in sub-Saharan Africa which covers 67% of the global HIV burden.This study aimed to investigate the proportion of viral suppression at an undetectable level and the risk of viral rebound among people living with HIV receiving ART in northern Tanzania.

METHODOLOGY

A hospital based-retrospective study recruited people living with HIV who were on ART for at least two years at Kibong'oto Infectious Disease Hospital and Mawenzi Regional Referral Hospital in Kilimanjaro Region, Tanzania. Participants' two-year plasma HIV were captured at months 6, 12, and 24 of ART. Undetectable viral load was defined by plasma HIV of viral load (VL) less than 20copies/ml and viral rebound (VR) was considered to anyone having VL of more than 50 copies/ml after having history of undetectable level of the VL less than 20copies/ml. A multivariable log-binomial generalized linear model was used to determine factors for undetectable VL and viral VR.

RESULTS

Among 416 PLHIV recruited, 226 (54.3%) were female. The mean (standard deviation) age was 43.7 (13.3) years. The overall proportion of undetectable VL was 68% (95% CI: 63.3-72.3) and 40.0% had viral rebound (95% CI: 34.7-45.6). Participants who had at least 3 clinic visits were 1.3 times more likely to have undetectable VL compared to those who had 1 to 2 clinic visits in a year (p = 0.029). Similarly, participants with many clinical visits ( > = 3 visits) per year were less likely to have VR compared to those with fewer visits ( = 2 visits) [adjusted relative risk (aRR) = 0.64; 95% CI: 0.44-0.93].

CONCLUSION

Participants who had fewer clinic visits per year(ART refills) were less likely to achieve viral suppression and more likely to experience viral rebound. Enhanced health education and close follow-up of PLHIV on antiretroviral therapy are crucial to reinforce adherence and maintain an undetectable viral load.

Trend and factors associated with non-suppression of viral load among adolescents on ART in Tanzania: 2018-2021

Background

Tanzania is one of the countries with a high burden of HIV. It has an estimated 1.4 million people living with HIV in 2021. Adolescents living with HIV on antiretroviral therapy (ART) have worse treatment adherence, viral suppression, and mortality rates compared to adults. This study aim was to determine the trend of non-suppression among adolescents on ART in Tanzania from 2018 to 2021 and latest associated predictors.

Methodology

The study utilized data of adolescents (10-19 years) receiving ART in Tanzania mainland for the period of 2018-2021 from the National Care and Treatment Centers database. The primary outcome of interest was non-suppression of viral load, defined as a VL above 1,000 copies/ml. The study employed multivariable logistic regression models to identify factors associated with non-suppression of VL. STATA 15 statistical software was used to analyze the data.

Results

Records of 65,942 adolescents present in the CTC database Tanzania were analyzed. Approximately more than half were female 38,544 (58.5%). The proportion of non-suppression was 34.5%, 23.3%, 12.1%, and 9.7% for the years 2018-2021, respectively. After adjusting for other factors, adolescents with a history of poor adherence to ART in the last six months had higher odds of non-suppression (OR = 1.95, 95% CI = 1.64, 2.31). Adolescents on second or third line ART regimens were almost two times more likely to be non-suppressed compared to those on first-line regimens (OR = 2.85, 95% CI = 2.52, 3.23). Girls had lower odds of non-suppression compared to boys (OR = 0.91, 95% CI = 0.84, 0.98), and similarly, patients attending hospitals had lower odds compared to those attending dispensaries (OR = 0.79, 95% CI = 0.72, 0.87).

Conclusion

Being female, having good history of adherence over the last six months, and attending hospital level was significantly associated with lower levels of non-suppression, while being on second line ART or attending lower health facilities increased the odds of non-suppression. Efforts to enhance the quality and capacity of health services at lower-level facilities (dispensaries and health centers) should be prioritized, as well as promoting gender-sensitive approaches that take into account the unique needs and experiences of adolescent girls and boys are needed to improve VL suppression among this population.

Adolescent's and youth's adherence to antiretroviral therapy for better treatment outcome and its determinants: multi-center study in public health facilities

BACKGROUND

Low-adherence to Anti-retroviral therapy (ART) negatively affects the clinical, immunological, and virologic outcomes of patients. Adherence is the most important factor in determining Antiretroviral Therapy (ART) treatment success and long-term viral suppression which ultimately reduces morbidity and mortality. Thus, this study aimed to identify factors affecting adherence to antiretroviral therapy among adolescents and youth living with HIV.

METHODS

Facility-based cross-sectional study was conducted from March 21 to April 30, 2020 among 316 respondents in selected five high-loaded hospitals with adolescent and youth clients using systematic random sampling technique. Patients' adherence was assessed when they had reportedly taken 95% or higher of their prescribed antiretroviral drugs in the five days before the interview. Data were collected, entered into EPI Data and exported to SPSS for analysis. Binary logistic regression was used to see the association between dependent and independent variables.

RESULTS

In this study, 316 respondents participated in the study, with a 99.7% response rate. The mean age of respondents were 17.94 years and majority of them (58.5%) were females. The overall ART adherence among adolescents and youths was found to be 70.6%. Being female (AOR = 0.323, 95% CI, 0.164-0.637), presence of opportunistic infection (AOR = 0.483, 95% CI, 0.249-0.936), taking additional medication beside ART (AOR = 0.436, 95% CI, 0.206-0.922) and availability of youth friendly services within the facility (AOR = 2.206, 95% CI, 1.031-4.721) were found to be predictors.

CONCLUSION

The adherence rate in this study was low which is below the recommended adherence level. Being female, taking additional medication beside ART and presence of opportunistic infection were determinants of adherence. As a result, significant work must be done on opportunistic infection prevention through health education and promotion for screening and risk reduction. Similarly, adolescents and youths service integration with the ART Clinic is strongly advised.

Medical Interns' Knowledge, Attitude, and Practice Toward People Living with HIV: Multicenter Experience from Saudi Arabia

Background

Discrimination by some healthcare providers toward people living with HIV/AIDS has been documented. Differences in cultural backgrounds make it harder for future doctors, who need a lot of knowledge and a positive attitude to treat patients. In conservative countries like Saudi Arabia, not enough is known about how much medical interns know about HIV and how they feel about people living with HIV/AIDS.

Methods

From April to September 2021, this cross-sectional study use non-probability random sampling and utilized a self-administered questionnaire to collected the data from 346 medical interns who had graduated from five different medical schools.

Results

Most of the subjects correctly identified the main transmission routes, such as unprotected sex (94.57%), blood and body fluid exchange (94.19%), and sharing needles or syringes (91.47%). But they did not know what the most common co-infections were for HIV patients or how to protect themselves after exposure. This paper showed that medical interns have some stigmatizing behaviors toward patients living with HIV, as 31.1% and 22.9% agreed, respectively, that they would feel more sympathetic toward people who get AIDS from blood transfusions compared to IV drug users (IDU).

Conclusion

Medical interns also showed some positive attitudes, as more than half of the sample (56.2%) would not isolate beds for people living with HIV/AIDS. The study's conclusion is that HIV education and training programs should be added for medical interns, which might have a significant positive impact on their attitude.

Failure to Attain HIV Viral Suppression After Intensified Adherence Counselling-What Can We Learn About Its Factors?

Background

Introduction and expansion of antiretroviral therapy (ART) have turned the tide of HIV pandemic, thus helping people living with HIV (PLHIV) achieve viral suppression. This success may need to be complemented by intensified adherence counseling (IAC) to improve adherence to treatment. However, some PLHIV still face higher than acceptable viral loads despite being on treatment.

Purpose

We investigated the factors associated with the failure to suppress HIV viral load after three months of IAC sessions.

Patients and Methods

This cross-sectional study analyzed secondary data from PLHIV-attended care and treatment clinics in Mwanza between January 2018 and December 2019 who had unsuppressed VL after being on ART for at least six months. We identified PLHIV in first-line ART with viral load evaluation before receiving IAC and had viral load results done at 90 days after IAC. We conducted descriptive statistics to examine the magnitude of viral suppression. Wilcoxon signed-rank test used to compare the median viral load before and after IAC sessions, and logistic regressions predicted the factors associated with failure.

Results

This study included 212 subjects. After intervention, most participants 85.9% (182) had significantly improved adherence compared to baseline. More than half 75.5% (160) of the participants had viral suppression after the intervention. Participants aged 18-25 years (AOR = 5.6, 95% CI, 1.1-29.6), unstable client during ART initiation (AOR = 0.3, 95% CI, 0.13-0.62), and poor adherence to ART (AOR = 4, 95% CI, 1.3-12.3) remained the main predictors of virological failure after IAC intervention.

Conclusion

Even though virological suppression is influenced by ART adherence, the findings in this study have shown co-existence of other factors to be addressed. Unstable during ART initiation is a new factor identified in this study.

Poor adherence to antiretroviral therapy among adult people living with HIV initiated during the COVID-19 epidemic waves – observations at the University Teaching Hospital in Lusaka, Zambia

Background

Coronavirus disease 2019 (COVID-19)-related disruptions in healthcare services and clinical outcomes have been predicted and documented. However, little is known about how antiretroviral therapy (ART) adherence disruptions caused by the COVID-19 pandemic have manifested amidst the ‘Undetectable = Untransmittable' campaign initiative. Using a patient's viral load as a proxy for medication adherence, our study aimed to determine the adherence to ART on first-line medications among adult people living with human immunodeficiency virus (PLWHIV) at the University Teaching Hospital in Lusaka, Zambia during the pandemic.

Methods

This was a hospital-based cross-sectional study. Secondary data of PLWHIV registered to receive ART from the Adult Infectious Disease Centre was extracted from the SmartCare® electronic health record system to constitute a resultant data set that this study used. The data extraction form was used to extract values of dependent (ART adherence measured by viral load detectability) and independent variables and imported them into the statistical analysis tool, STATA version 16.1 MP. Descriptive statistics of individual characteristics, testing for associations using Pearson's chi-square test, and stratified and combined multivariable logistic regression were performed.

Results

Of the 7,281 adult PLWHIV included in this study, 9.0% (95% CI 8.3–9.6%) were virally detectable. Estimates of the odds ratios of detectable viral load remained significantly higher among adult PLWHIV who were initiated on ART after the U=U campaign was launched in Zambia and were on a monthly 2.51 (1.31–9.03) or 6-monthly 4.75 (3.52–6.41) dispensing of a dolutegravir-based regimen and those on 6-monthly dispensing of an efavirenz-based regimen 4.67 (2.16–10.08) compared to their counterparts. Overall estimates showed us the same picture 4.14 (3.22–5.31), having adjusted for all other predictor variables.

Conclusion

We found that a high proportion of people with detectable viral load in the study population, irrespective of medication refill interval and type of regimen, was concentrated among adult PLWHIV who started treatment during the COVID-19 epidemic waves, as compared to those who started treatment before the pandemic. This observed disparity suggests the inherent impact of the pandemic on the adherence to ART among adult PLWHIV in Lusaka, Zambia. This further illustrates how exposed program responses are to external shocks, especially in already weakened health systems, and the need to create program response buffers and resilient program-specific strategies to minimize the effect of external disruptions.

Sexual Behaviour and Attitudes towards Safe Sex of Youth Receiving Antiretroviral Care at Public Health Facilities in Palapye District, Botswana

BACKGROUND

Sexual behaviour of HIV-infected youths is very important in determining the direction of the HIV epidemic, as these youths are reservoirs of HIV and can propagate its transmission if they engage in risky sexual behaviours. However, support structures for secondary prevention are weak even in healthcare settings. There is a need to understand the sexual behaviour of these youths and, in turn, tailor appropriate secondary prevention strategies, hence the current study was designed to assess sexual behaviour and attitudes towards safe sex of youth receiving antiretroviral care at public health facilities in Palapye district, Botswana.

METHOD

This quantitative, descriptive cross-sectional survey was used to describe the sexual behaviour and attitudes towards safe sex and identify factors associated with risky sexual behaviours among HIV-infected youths aged between 15 and 19 years receiving antiretroviral therapy (ART) care from public healthcare facilities in Palapye District, Botswana.

RESULTS

A total of 188 youths participated in this study, 56% being females while 44% were males. We reported that 15.4% had ever had sex. At their last sexual encounter, more than half of the youths (51.7%) had not used condoms. More than a third of the participants were under the influence of alcohol during their last sexual experience. Generally, the youths had good attitudes towards safe sex, as most youths said they would prioritise protecting their sexual partners and themselves from HIV and STIs. Alcohol use, substance use and not considering religion as important were strongly associated with having ever had sex.

CONCLUSIONS

A significant proportion of HIV-infected youths are sexually active, whereas their preventive practices such as condom use are poor despite good attitudes towards safe sex. Alcohol use, substance use and not perceiving religion as important were associated with risky sexual behaviours.

Closing the HIV Treatment Gap for Adolescents in Windhoek, Namibia: A Retrospective Analysis of Predictors of Viral Non-Suppression

Windhoek joined the Fast-Track Cities Initiative in 2017 to optimize HIV service delivery for adolescents, promoting adherence and sustaining viral suppression. Recent surveys and programmatic data show that the treatment gap remains greatest among children and adolescents living with HIV. A retrospective cohort analysis of adolescents living with HIV (ALHIV) receiving antiretroviral therapy (ART) at Windhoek healthcare facilities was conducted. Routine clinical data were extracted from the electronic Patient Monitoring System (ePMS). The SPSS statistical package was used to determine viral non-suppression and perform inferential statistics. 695 ALHIV were analysed with median age of 16 years (IQR = 13-18). Viral non-suppression at 1000 copies/mL threshold was 12%. Viral non-suppression was associated with age at ART initiation, duration on ART, current ART regimen and WHO Clinical Stage. In multivariate analysis, longer duration on ART was a protective factor for viral non-suppression (13-24 months vs. >24 months: aOR = 8.92, 95% CI 2.60-30.61), while being on third line regimen (vs. first line) was protective against viral non-suppression (aOR = 0.11, 95% CI 0.03-0.49). A significant treatment gap is evident for ALHIV with high viral non-suppression levels. Interventions are required to counter treatment fatigue to keep adolescents engaged in ART, and timely switching to rescue regimens for failing adolescents.

Kharsany A, Zewotir T, North D. Spatial Variation and Factors Associated with Unsuppressed HIV Viral Load among Women in an HIV Hyperendemic Area of KwaZulu-Natal, South Africa

New HIV infections among young women remains exceptionally high and to prevent onward transmission, UNAIDS set ambitious treatment targets. This study aimed to determine the prevalence, spatial variation and factors associated with unsuppressed HIV viral load at ≥400 copies per mL. This study analysed data from women aged 15–49 years from the HIV Incidence Provincial Surveillance System (HIPSS) enrolled in two sequential cross-sectional studies undertaken in 2014 and 2015 in rural and peri-urban KwaZulu-Natal, South Africa. Bayesian geoadditive model with spatial effect for a small enumeration area was adopted using Integrated Nested Laplace Approximation (INLA) function to analyze the findings. The overall prevalence of unsuppressed HIV viral load was 45.2% in 2014 and 38.1% in 2015. Factors associated with unsuppressed viral load were no prior knowledge of HIV status, had a moderate-to-low perception of acquiring HIV, not on antiretroviral therapy (ART), and having a low CD4 cell count. In 2014, women who ever consumed alcohol and in 2015, ever ran out of money, had two or more lifetime sexual partners, ever tested for tuberculosis, and ever diagnosed with sexually transmitted infection were at higher risk of being virally unsuppressed. The nonlinear effect showed that women aged 15 to 29 years, from smaller households and had fewer number of lifetime HIV tests, were more likely to be virally unsuppressed. High viral load risk areas were the north-east and south-west in 2014, with north and west in 2015. The findings provide guidance on identifying key populations and areas for targeted interventions.
