Abstract Background: Suboptimal adherence results in inadequate drug exposure and increases the likelihood of viral replication and resistance, limit future therapeutic options. A high level of adherence is very crucial to maximize the usefulness of antiretroviral therapy. This study aimed to examine factors associated with non-adherence to antiretroviral therapy among adolescents in Guji Zone, South Ethiopia.Methods: Institution based case-control study design was employed on adolescent clients on antiretroviral therapy in the ART clinic of Guji zone health facilities from 26 February to 20 April 2018. Cases and controls were recruited by a consecutive sampling method. Bivariate and multivariable logistic regression was done using SPSS version 20 at 95% Confidence Interval (CI) and a precision of 5%.Results: A total of 297(101 cases and 196 controls) adolescents on ART participated in this study. Being rural residents AOR 1.9(1.1-3.6), Living with unmarried/widowed and separated caregivers AOR 2.1(1.2-3.8), living with unemployed caregivers AOR 4.2(2.0-8.9), not disclosing HIV Status AOR 5(2.8-9.4), having symptom of depression for adolescents AOR 2.7(1.5-4.9), not using reminding methods AOR 2.4(1.2-4.8) and Uses of other drugs besides ART AOR 2.6(1.5-5.0) were found to be independent factors associated with non-adherence to ART among adolescents.Conclusion: -Residence area, caregiver marital status, sources of income for the family, disclosure status, depression status, uses of reminding methods, and uses of other drugs besides ART were factors associated with non-adherence to antiretroviral therapy among adolescents. Support from peers and family can promote adolescent's adherence, as it buffers the stress associated with the illness, encourages optimism, reduces depression, and improves healthful behaviors. The provision of health education on the importance of treatments and needs for adherence should be encouraged. Uses of reminding methods, continuous monitoring of clients on ART regarding the uses of medications other than antiretroviral therapy is important.

Abstract Background: Low level viremia (LLV) often occurs during antiretroviral therapy (ART) against HIV-1. However, its impact on virologic failure (VF) is controversial because of non-uniform definitions of LLV and VF. Methods: A long-term first line regimen ART cohort from 2002–2018 from Shenyang, northeast China, was retrospectively studied. All participants were followed up every 3 to 6 months to evaluate the treatment effect. The high-risk LLV subgroups leading to VF (with strict standards) were explored with Cox proportional hazards model and linear mixed-effect model. The association factors of high-risk LLV were further explored using multivariate logistic regression analyses. Results: A total of 2155 HIV-1 infected participants were included; of these, 38.8% showed LLV. Both high level LLV (HLLV) and any other level LLV coupled with high level blip (HBL) showed higher risk of VF (hazards ratios, HRHLLV=5.93, and HRHBL=2.84, p<0.01 respectively). Moreover, HR increased with prolonged duration of LLV. Independent factors associated with high-risk LLV included the zenith baseline viral load (VL) above 6 log copies/ml (aOR=3.49, p=0.002), nadir baseline CD4+T cell counts below 200 cells/ml (aOR=1.78, p=0.011), Manchu (aOR=2.03, p=0.003), ART over 60 months (aOR=1.81, p=0.004), AZT+3TC+NVP (aOR=2.26, p<0.001) or DDI-based regimen (aOR=9.96, p<0.001), and subtype B’ infection (aOR=8.22, p=0.001). Conclusions: In case of VF with strict standards, high-risk LLV leading to VF includes VL above 400 copies/ml, occurring at least once. Serious laboratory indicators or advanced stage of infection, long term ART and subtype B’ infection might also predict the occurrence of high-risk LLV.

Introduction: Suboptimal adherence to antiretroviral therapy (ART) is a major hinderance to achieving the 90 90 90 goals in limited resources settings. South Ubangi province in DR Congo faces countless challenges providing universal HIV care. However, the level of ART adherence and associated factors among people on HIV treatment in this province remains unknown. Using a quantitative method approach, this study aimed to know the extend of adherence and to identify the determinants of optimal and suboptimal adherence among study participants. Methods: A cross-sectional research design was used to survey patients on ART in Gemena Referral Hospital. Results: After a simple randomly sampling from a sampling frame of 503 patients on treatment and who met the inclusion criteria of been using HIV treatment for at least one year, 438 were selected taking the even numbers in three rounds, but only 398 patients consented to participate to the study. Logistic regression was run to explore determinants of the adherence. The participants’ mean age was 42 years old (range: 8-62 years old). 280 participants were Female (=70.4%) and 118 were male (29.6%) with a sex ratio Female-male of 2.4/1. Most of the participants were married 185(46.5%), 45 were divorced (=1.3%), 136 widow/widowers (34.2% made up of 116 widowers=29% and 20 widows=4.2%) and only 32 were unmarried (8%). Among the married, 117 had only one partner (29% of overall), 42 had more than one partner (11%) and 26 were in a mere cohabitation (6.5%). ART adherence was 77% in the study population, while it should reach the optimal level of 95%. Adherence was positively associated with age, but suboptimal adherence was significantly associated with forget to take the drugs, distance, the degree of contentment to the family support, and moving out of home. Adherence was likely associated with age, in fact, old participants(44-60 age group) had 8.3 times an increased probability of being adherent( 2.30-8.84, 95% CI, p-value=0.001) compared to 8-25 age group. Additionally, taking his pills on daily basis had 1.68 times an increased probability of optimal adherence (1.39-1.98, 95% CI, p-value<0.001), compared to those patients who sometimes forget to take their pills. Distance < or = 5 km also had 2.47 an increased probability of being adherent (2.06-2.87, p-value<0.001) compared to people who live beyond 5 km from the health facility. Participants who stated they had a high degree of contentment to family support presented 1.93 times an increased probability of being adherent (1.93-1.46, 95% CI, p-value=0.001) compared with those with low degree of contentment to the family support. Participants who were resident had 1.55 times an increased significant probability to be adherent (1.28-1.82, 95% CI, p-value<0.001), compared to those who temporarily/definitely moved out their home for any reason. Gender, marital status, and monthly income did not have a significant association with adherence to antiretroviral therapy among people surveyed in the study. Conclusion: Suboptimal adherence is still a serious issue among ARVs users in resource limited settings. Further strategies to boost adherence to the optimal level and beyond would imply to increase personal capacities to adhere to therapy instructions, lessen stigma and discrimination barriers by the proxy and within patients’ families and foster the implication of the family members and the community in therapy, promote drugs provisions at home and differentiated health care management, etc.

Suboptimal Adherence

Systemic concentrations of antiretroviral drugs (ARVs) are influenced by the pharmacokinetic properties of absorption, distribution, metabolism, and excretion. Pharmacokinetics and local drug exposure can differ significantly within anatomical sanctuary sites compared with the systemic compartment. High variability in interpatient ARV concentrations is common, which makes population pharmacokinetics for ARVs very difficult to interpret. HIV replication is dynamic and requires combination antiretroviral therapy with multiple active agents in order to achieve durable virologic suppression. Direct and indirect relationships between drug exposure, efficacy, and/or toxicity are common for most ARVs, which can be used to improve overall treatment success. Suboptimal adherence can result in inadequate concentrations, drug resistance, and virologic failure. Therapeutic drug monitoring can be considered in certain scenarios that should be evaluated on a case-by-case basis.

Abstract IntroductionNigeria has the second largest HIV burden in Sub-Saharan Africa, with high burden amongst children and adolescents. In 2017, it was estimated that 160,000 children (0-9 years) and 230,000 adolescents (10-19 years) are living with HIV globally, with death in 21,000 children and 5400 adolescents resulting from AIDS-related illnesses. The main objective of the study was to determine the factors associated with poor viral suppression in children and adolescents accessing antiretroviral therapy in secondary health facilities in Lagos State.MethodsA descriptive retrospective study of children and adolescents living with HIV accessing care and support in 7 Global Fund supported ART treatment facilities in Lagos between January 2013 and June 2020. Data extraction was done between July 2020 and August 2020. The sociodemographic, clinical and laboratory data were extracted from patients’ folders. Binary logistic regression model was done to identify the determinants of viral non-suppression among children and adolescents age groups. ResultsThe study population consisted of 363 children (age 0-9 years) and 275 adolescents (age 10-19 years). The mean age of children was 5.8±2.2 years and that of adolescent was 13.21±2.8years. About 256(70 %) of children were virally unsuppressed and 118(43 %) had non-suppressed viral load status among adolescents. Binary logistic regression showed that children with WHO stage IV of HIV disease had greater odds (OR=7.984, 95% CI=1.042-61.163) of having suppressed viral load and children who live with their non-biological caregiver had greater odds of having a suppressed viral load compared to the biological caregiver group (OR=2.0421, 95% CI=1.083-10.965). Among adolescents, binary logistic regression showed location of abode and drug pick-up pattern as independent predictors of poor viral suppression. Adolescent patients living in rural setting had greater odds of being virally unsuppressed compared to those living in urban settlement (OR=1.755, 95% CI=1.001-3.083) while patients who have regular drug pick-up pattern from their ART health centres had lesser odds (OR=0.585, 95% CI=0.591-0.912) of viral non-suppression.CONCLUSIONThe findings highlight the need for a renewed focus on developing and strengthening HIV programmes in rural areas where children and adolescents living with HIV are more likely to be virally unsuppressed. More emphasis and resources should be channelled to Public health intervention such as health education, social support group programmes to improve drug pick up and adherence in adolescents living with HIV.
