Antiretroviral treatment (ART) adherence is highlighted in management of patients living with human immunodeficiency virus. In South Korea, ART medication research has rarely been conducted due to the low economic burden associated with government-funded treatment. This cross-sectional study aimed to compare the pill burden impact between ART regimen compliance and HIV-RNA viral load suppression. Data were collected from 2008 to 2016 at a general hospital in South Korea. A total of 210 HIV/AIDS treatment-naïve patients were grouped as follows: single-tablet regimen (STR, one tablet/day), mild pill burden (two-four tablets/day), and heavy pill burden (≥ five tablets/day). Patients were analyzed according to gender, age at index date, medical insurance type, comorbidities, depression, HIV/AIDS disease burden as indicated by HIV-RNA viral load and CD4, and laboratory variables. In a multivariate logistic regression model, the STR group demonstrated adherence 5.10 times more often than the heavy pill burden group. Females and patients with an initial viral load of 500,000 or more were 0.090- and 0.040-fold less adherent to the ART regimen. Among these patients, 95% or more of the MPR group were 7.38 times more likely to have a lower limit of detection (LLOD) of viral load suppression. The highest initial viral load group was 0.090-fold less likely to have an LLOD than the reference group. These results suggest that a single-tablet regimen could improve medication adherence and the clinical virologic outcome. Therefore, general population research on ART adherence and polypharmacy is needed.

Abstract Background A key goal of Antiretroviral Treatment (ART) is to achieve and maintain durable viral suppression. Thus, the most important use of viral load measurement is to monitor the effectiveness of therapy after initiation of ART. The main objective of the study was to determine the time for virological suppression and its associated factors among people living with HIV taking antiretroviral treatments in East Shewa Zone, Oromiya, Ethiopia. Methods Patients diagnosed with Human Immunodeficiency Virus presenting to the study health centers between October 3, 2011 and March 1, 2013 were included in the study given the following criteria: age 18 years or greater, eligible to start ART. All patients with baseline viral load measurements were included in the study. Interaction between explanatory variables with the response variable was analyzed by using cross tab features of (Statistical Package for the Social Sciences) SPSS, International Business Machines (IBM) Inc. Significance group comparison was done by Kaplan Meier log-rank test. Cox proportional hazard model was used to select significant factors to the variability between groups. Result Plasma viral load was suppressed below the detection level in 72% of individuals taking a different regimen of ART. The median Human Immunodeficiency virus (HIV)-1 plasma viral load in the cohort was estimated to be log 5.3111 copies/ml. The study observed Survival curve difference in the category of marital status (p-value 0.023) and baseline cluster of differentiation 4 (CD4) value (p-value 0.023). The estimated median time to Plasma Viral Load (PVL) suppression was 181 days (CI: 140.5–221.4) with the age group of 30–39 years having minimum time to achieve suppression with 92 days (CI: 60.1–123.8) and the maximum time required to reach the level was found among the age group between 50 and 59 years. Conclusion The study found that the estimated time to achieve PVL after taking ART to be 181 days. Factors affecting time to suppression level were marital status and baseline CD4.

Background: HIV viral load suppression (VLS) is the most important indicator of successful antiretroviral therapy. In 2016, Bulambuli District started monitoring HIV patients on ART using viral load tests in an effort to meet the third 90 of the UNAIDS 90-90-90 strategy which is VLS. The objective of this study was to determine the progress in Bulambuli District towards achievement of VLS among HIV infected patients on ART and associated factors that affect this programme. Methods: A retrospective cohort study design was used. One thousand, one hundred and one medical records of HIV infected patients on ART who attended HIV clinic at Muyembe Health Centre IV from June 2016 to April 2018 were reviewed. A data abstraction tool was used for data collection. Chi Square was used to determine factors associated with VLS and logistic regression was used to determine the magnitude by which the ART and clinical factors influence VLS. Data were summarized using descriptive statistics for categorical variables and by computing proportions, means and standard deviation for continuous variables. Results: Of the patients (n = 944, 85.7%) had attained VLS. Adjusting for known confounders, only adherence to ART was a significant predictor of VLS. Individuals with fair adherence (80%-95%) had 2.667 times the odds of VLS, CI = 1.122-9.370, P-value of <.002 compared to individuals with good (>95%) adherence which was used as the reference while those with poor (<80%) adherence had 4.553 times the odds of attaining VLS, CI = 1.31-13.930, P-value of <.001 compared to individuals with good adherence. Conclusion: These findings suggest that Bulambuli District, at 85.7% VLS is on track to attaining the third 90 of the 90, 90, 90 global targets by 2020. It further reveals that adherence is the only significant predictor of VLS in the District.

Abstract Background Drug potency is a pharmacological parameter defining dose or concentration of drug required to obtain 50% of the drug’s maximal effect. Pharmacokinetic-pharmacodynamic modelling and simulation allows estimation of potency and evaluate strategies improving treatment outcome. The objective of our study is to determine potency of atazanavir in hair, defined as atazanavir level in hair associated with 50% probability of failing to achieve viral load below 1000 copies/ml among adolescents, and explore the effect of participant specific variables on potency. Methods A secondary analysis was performed on data from a previous study conducted in HIV-infected adolescents failing 2nd line ART from Harare central hospital, Zimbabwe, between 2015 and 2016. We simulated atazanavir concentrations in hair using NONMEM (version 7.3) ADVAN 13, based on a previously established pharmacokinetic model. Logistic regression methods were used for PKPD analysis. Simulations utilising PKPD model focused on estimation of potency and exploring the effect of covariates. Results The potency of atazanavir in hair was found to be 4.5 ng/mg hair before adjusting for covariate effects. Participants at three months follow-up, reporting adequate adherence, having normal BMI-for-age, and cared for by mature guardians had increased potency of atazanavir in hair of 2.6 ng/mg, however the follow-up event was the only statistically significant factor at 5% level. Conclusion Atazanavir in hair in the range 2.6 to 4.5 ng/mg is associated with above 50% probability of early viral load suppression. Adherence monitoring to adolescents with lower potency of atazanavir is recommended. The effect self-reported adherence level, BMI-for-age, and caregiver status require further evaluation.

Abstract Background Progress toward the global target for 95% virological suppression among those on antiretroviral treatment (ART) is still suboptimal. We describe the viral load (VL) cascade, the incidence of virological failure and associated risk factors among people living with HIV receiving first-line ART in an HIV cohort in Myanmar treated by the Médecins Sans Frontières in collaboration with the Ministry of Health and Sports Myanmar. Methods We conducted a retrospective cohort study, including adult patients with at least one HIV viral load test result and having received of at least 6 months’ standard first-line ART. The incidence rate of virological failure (HIV viral load ≥ 1000 copies/mL) was calculated. Multivariable Cox’s regression was performed to identify risk factors for virological failure. Results We included 25,260 patients with a median age of 33.1 years (interquartile range, IQR 28.0–39.1) and a median observation time of 5.4 years (IQR 3.7–7.9). Virological failure was documented in 3,579 (14.2%) participants, resulting in an overall incidence rate for failure of 2.5 per 100 person-years of follow-up. Among those who had a follow-up viral load result, 1,258 (57.1%) had confirmed virological failure, of which 836 (66.5%) were switched to second-line treatment. An increased hazard for failure was associated with age ≤ 19 years (adjusted hazard ratio, aHR 1.51; 95% confidence intervals, CI 1.20–1.89; p < 0.001), baseline tuberculosis (aHR 1.39; 95% CI 1.14–1.49; p < 0.001), a history of low-level viremia (aHR 1.60; 95% CI 1.42–1.81; p < 0.001), or a history of loss-to-follow-up (aHR 1.24; 95% CI 1.41–1.52; p = 0.041) and being on the same regimen (aHR 1.37; 95% CI 1.07–1.76; p < 0.001). Cumulative appointment delay was not significantly associated with failure after controlling for covariates. Conclusions VL monitoring is an important tool to improve programme outcomes, however limited coverage of VL testing and acting on test results hampers its full potential. In our cohort children and adolescents, PLHIV with history of loss-to-follow-up or those with low-viremia are at the highest risk of virological failure and might require more frequent virological monitoring than is currently recommended.

ObjectivesHIV point-of-care testing (POCT) has been available in Manitoba since 2008. This study evaluated the effectiveness of POCT at identifying individuals with previously unknown HIV status, its effects on clinical outcomes and the characteristics of the populations reached.MethodsA retrospective database review was conducted for individuals who received HIV POCT from 2011 to 2014. Time to linkage to care and viral load suppression were compared between individuals who tested positive for HIV using POCT and controls identified as positive through standard screening. Testing outcomes for labouring women with undocumented HIV status accessing POCT during labour were also assessed.Results3204 individuals received POCT (1055 females (32.9%) and 2149 males (67.1%)), being the first recorded HIV test for 2205 (68.8%). Males were more likely to be targeted with POCT as their first recorded HIV test (adjusted OR (AOR) 1.40). Between the two main test sites (Main Street Project (MSP) and Nine Circles Community Health Centre), MSP tested relatively fewer males (AOR 0.79) but a higher proportion of members of all age groups over 30 years old (AOR 1.83, 2.51 and 3.64 for age groups 30–39, 40–49 and >50, respectively). There was no difference in time to linkage to care (p=0.345) or viral load suppression (p=0.405) between the POCT and standard screening cohorts. Of 215 women presenting in labour with unknown HIV status, one was identified as HIV positive.ConclusionsPOCT in Manitoba has been successful at identifying individuals with previously unknown HIV-positive status. Demographic differences between the two main testing sites support that this intervention is reaching unique populations. Given that we observed no significant difference in time to clinical outcomes, it is reasonable to continue using POCT as a targeted intervention.MeSH termsHIV infection; rapid HIV testing; vertical infectious disease transmission; community outreach; service delivery; marginalised populations.
