Abstract
Human immunodeficiency virus (HIV) infection remains a serious public health concern, with an estimated 38 million people living with HIV (PLHIV). PLHIV are often affected by mental disorders at higher rate than the general population. One challenge in the control and prevention of new HIV infections is adherence to antiretroviral therapy (ART), with PLHIV with mental disorders having seemingly lower adherence than PLHIV without mental disorders. This cross-sectional study assessed adherence to ART in PLHIV with mental disorders who attended the Psychosocial Care Network health facilities in Campo Grande, Mato Grosso do Sul, Brazil, from January 2014 to December 2018. Data from health and medical databases were used to describe clinical-epidemiological profiles and adherence to ART. To assess the associated factors (potential risk or predisposing factors) with ART adherence, we used logistic regression model. Adherence was extremely low (16.4%). Factors associated with poor adherence were lack of clinical follow-up, particularly in middle-aged PLHIV. Other apparently associated factors were living on the streets and having suicidal ideation. Our findings reinforce the need for improvements in the care for PLHIV with mental disorders, especially in the integration between specialized mental health and infectious disease health facilities.

Abstract
BACKGROUND Nonadherence to antiretroviral therapy (ART) may lead to viral replication and development of antiretroviral resistance. OBJECTIVE To identify the factors associated with nonadherence to ART among people living with the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (PLWHA). DESIGN AND SETTING Cross-sectional study in a tertiary-level hospital in northeastern Brazil. METHODS Intake of less than 90% of the antiretroviral drugs prescribed in the last week prior to the interview was defined as nonadherence. Intake was evaluated using a questionnaire. Descriptive and multivariate analyses were conducted on the study population, with estimation of the respective odds ratios and 95% confidence intervals. RESULTS The prevalence of nonadherence was 28.4%. Significant associations were found regarding the following variables: age less than 35 years, smoking, sedentary lifestyle, lack of medication and lack of knowledge regarding the patient's HIV status, on the part of the patient's partner or family. CONCLUSIONS Encouragement of adherence to antiretroviral therapy is one of the fundamental pillars of treatment for HIV-infected patients. The high proportion of nonadherence (28.4%) and the predictive factors related to this indicate that it is necessary to improve patients' adherence to antiretroviral therapy.

Abstract
AIDS is an advanced clinical manifestation of HIV infection. It generates severe immunodeficiency and associated infections that may lead to death. The antiretroviral therapy (ART) has reduced the morbimortality of HIV/AIDS, but its benefits depend on ART adherence. This integrative review followed the PICO method to identify factors associated with adult adherence to ART. Empirical papers published between January 2010 and December 2016 in the Medline, SciELO, Lilacs and PePSIC databases were included. We analyzed 125 papers regarding the characteristics of studies, adherence measures and associated factors. Results showed a wide variety in the definition of adherence and the use of measures for its monitoring, as well as several adherence-associated factors. These were categorized as follows: 1- Individual variables; 2- Treatment characteristics; 3- HIV/aids infection characteristics; 4- Relationship with the health services; 5- Social support. Health services should characterize the users' profiles, systematize adherence measures and regionally assess adherence-associated factors for the early detection of non-adherence to ART and implementation of effective intervention plans.

Abstract
O principal objetivo do monitoramento de adesão a terapia antirretroviral (TARV) é manter os portadores do Vírus da Imunodefi ciência Humana (HIV) com carga viral indetectável. A adesão do paciente à TARV é um processo dinâmico, multifatorial que requer decisões compartilhadas e corresponsabilizadas entre ousuário do serviço, a equipe de saúde e a rede social de apoio, visando atender às singularidades socioculturais, melhorando a qualidade de vida dos pacientes com HIV. Existem vários nos métodos de avaliação da aderência disponíveis, com diferentes implicações para as práticas clínicas e de pesquisa, porém não está defi nido um método padrão-ouro. Tendo em vista que a efetividade da terapia depende diretamente do engajamento dos pacientes, o estudo visa expor, mediante revisão de literatura, as principais barreiras encontradas nesse contexto e as diversas estratégias utilizadas na prática clínica para promover a adesão integral dos indivíduos portadores de HIV ao tratamento.

Abstract
Treatment of AIDS involves the use of the cocktail of drugs that make up the antiretroviral therapy. Its logistic control is monitored by a computerized national system of dispensation, the Logistic Control System of Medication (SICLOM). This study aimed to investigate, by means of SICLOM data, the use of antiretroviral therapy in patients treated at two University Hospitals in the state of Rio de Janeiro. A cross-sectional study was conducted with sociodemographic and dispensation data collected from SICLOM. The evaluation of drug ownership was done by calculating the Proportion of Days Covered (PDC). Five hundred and thirty-eight patients of both genders with active registration in SICLOM and over 18 years of age were included. The ART most used in both hospitals was lamivudine, considering the total of 58 different schemes identified. The mean of possession of groups was 88% (± 0,16). The factor associated with possession of drugs was the ART scheme, with PDC of 91% (p<0,001) for rescue schemes. This study confirmed that SICLOM was a reliable source to establish the profile of the population assisted.

Abstract
A critical feature of an adherence assessment tool is its ability to predict virologic failure in people living with HIV (PLHIV). We, therefore, aimed to compare the predictive performance of commonly used adherence measures. We systematically searched MEDLINE, Embase and LILACS up to February 2018, to identify relevant observational studies comparing the effects of any two of the following adherence measurements on virologic outcomes: electronic monitoring, pill count, pharmacy refill, self-report and physician assessment. We analyzed data by pairwise meta-analyzes with a random-effects model. The proportion of virologic failures among non-adherent participants in each adherence measure was used to calculate the odds ratio (OR), with 95% Confidence Intervals (95%CI). Heterogeneity was assessed, with potential causes identified by sensitivity and subgroup analysis. We included 38 studies with individual patient data for 18,010 patients. All possible comparisons between pairs of the five adherence measures were considered and a total of nine comparison groups could be established. Meta-analysis suggested that self-report was a better predictor of virologic failure than pill count when the recall period was within one week (OR: 2.35, 95%CI: 1.07-5.18, p = 0.03). Physician assessment had higher odds of predicting virologic failure than did either self-report (OR: 2.63, 95%CI: 1.37-5.26, p < 0.01) or pharmacy refill (OR: 3.57, 95%CI: 1.69-7.14, p < 0.001). There was no difference in the predictive performance between any of the other measures that we were able to compare (p > 0.05). The combination of multiple measures did not increase the predictive value when compared to any of the measures alone. Low-cost and simple adherence measures such as self-report predict virologic failure better than or equally well as objective measures. Our results suggest that there is no need to use expensive or time-consuming adherence measures when the objective is to identify PLHIV at risk of treatment failure.

Abstract
BACKGROUND Adherence to antiretroviral (ARV) therapy remains a major challenge in HIV therapeutics. OBJECTIVE To assess the adherence to ARV therapy by measuring the delay in monthly refilling of ARV drugs using pharmacy records and to correlate this with HIV plasma RNA measurements and CD4+ cell count. METHOD Records of 170 HIV-positive patients were examined to identify HIV viral load (VL)/CD4+ results and the time interval to refill ARVs at the pharmacy. The correlation between the number of days missed to refill ARVs and plasma HIV-RNA detectability/CD4+ count was performed using the Spearman's correlation coefficient (r). RESULTS Fewer days missed to refill ARV was positively correlated with undetectable VL and increase in CD4+ count (r = 0.407 and 0.237, respectively). Increase in adherence was correlated with longer retention in the cohort (r = 0.208). CONCLUSION Monitoring the delay to pick up ARVs from the pharmacy can be an important and simple tool to identify patients requiring assessment of their adherence.

Abstract
OBJECTIVE To present the development and validation of the WebAd-Q Questionnaire, a self-report instrument to monitor adherence to antiretroviral therapy in HIV/AIDS centers in Brazil. METHODS The WebAd-Q is an electronic questionnaire that has three questions about the use of antiretrovirals in the last week. It was constructed from interviews and focus groups with 38 patients. Its validity was tested in a study with a sample of 90 adult patients on antiretroviral therapy for at least three months. We used electronic monitoring bottles, pill counting, and self-report interview to compare adherence. The WebAd-Q was answered on the sixtieth day, twice, with at least one hour of interval. The viral load of the patients was obtained from the service records. We have analyzed the agreement between the answers to the WebAd-Q, the associations, and the correlations with viral load and performance compared to other measures of adherence. RESULTS Among the invited patients, 74 (82.2%) answered the WebAd-Q. No difficulties were reported to answer the questionnaire. The average answer time was 5 min 47 sec. The set of three questions of the WebAd-Q obtained agreement of 89.8%, with Kappa of 0.77 (95%CI 0.61-0.94). The non-adherence answers of the WebAd-Q were associated with detectable viral load. We obtained moderate viral load correlations with the non-adherence scale according to the WebAd-Q. For the three questions of the WebAd-Q, patients with non-adherence answers were also reported as less adherent according to the other measures of adherence. CONCLUSIONS The WebAd-Q answered all the issues considered relevant in the validation of questionnaires, was well understood by patients, was associated with viral load, and obtained good agreement and good performance compared to the other measures. The feasibility analysis of its implementation still depends on a national study on its applicability.

Abstract
INTRODUCTION Patient adherence to antiretroviral therapy (ART) is critical for HIV treatment success. Monitoring rates of adherence in public HIV outpatient care facilities can improve outcomes in Brazil where ART is universally available. METHODS We conducted a national cross-sectional survey of ART adherence in 2010. Participants were selected using a multistage probability sample. First, HIV outpatient care facilities were stratified according to 7 Organizational Quality Classification (OQC) groups and regions. Second, 1 or 2 facilities were selected per region for each OQC group. Finally, patients were randomly selected at each facility. In a first component, patients were invited to answer to a web-based questionnaire (WebAd-Q), a validated self-reported tool that includes 3 questions on adherence to ART in the past 7 days (time scheduling-timing, drug regimen-medication, and pill counts-dose), herein named indicators of potential nonadherence (IPN). In addition, a subsample of participants were interviewed in order to obtain further data on sociodemographic and clinical characteristics (second component). The proportion of each IPN was estimated using weighted data to account for the sampling design with 95% confidence interval (CI) and descriptive analysis was carried out. RESULTS Fifty-five facilities were chosen and 2424 patients completed the WebAd-Q in the first component of the study, while 598 patients were interviewed for the second component. The weighted proportions of the IPN were 50.9%, 31.8%, and 19.5%, for timing, medication, and dose, respectively, while11.7% had all 3 indicators, varying from 5.9% in the Southeast and 21.9% in the Northeast regions. Overall, 61.1% of the patients had at least 1 IPN (95% CI: 58.5-63.7%). Patients reporting depression symptoms, illicit drug use and those who missed medical appointments had worse nonadherence outcomes. CONCLUSIONS Overall, there was a high proportion of all indicators IPN and timing was the main component associated with low adherence. Although these indicators may not necessarily indicate individual nonadherence, they represent a worrisome scenario in the public Brazilian HIV care facilities. On a routine basis, these facilities can identify gaps in providing counseling and ART orientation to their clientele and develop innovative strategies to prevent nonadherence.

Abstract
BACKGROUND Multiple studies have identified a relationship between the complexity of a medication regimen and non-adherence. However, most studies in people who live with HIV (PLWH) have focused on antiretroviral use and have failed to consider the impact of other medications. OBJECTIVE The aim of our study is to identify the Medication Regimen Complexity Index (MRCI) as an associated factor for nonadherence to antiretroviral treatment (ART). The secondary aim is to analyze the relationship between clinical and pharmacotherapeutical variables and adherence to antiretroviral treatment and to generate an adherence model. METHODS A transversal, observational study. Patients included were PLWH over 18 years of age on active antiretroviral therapy. Patients who participated in clinical trials or who did not meet the inclusion criteria were excluded. We had studied HIV transmission mode, viral load, treatment status, number of comorbidities and complexity index as factors associated with adherence to ART. RESULTS We included 619 patients in the study. Number of comorbidities ( p = 0.021; OR = 1.038-1.570); viral load ( p = 0.023; OR = 1.108-4.505) and MRCI ( p < 0.001; OR = 1.138-1.262) (ART and concomitant treatment) were the independent associated factors to ART nonadherence. The value of the Hosmer and Lemeshow test confirmed the validity of this model (P = 0.333). CONCLUSION A higher MRCI was associated with non-adherence. Therefore, the regimen complexity calculation may be appropriate in daily practice for identifying patients at a higher risk of becoming non-adherent.

Abstract
OBJECTIVES The aim of the present study was to investigate the prevalence of depression and adherence to antiretroviral treatment in two groups of individuals: men who have sex with men (MSM) and men who have sex with women (MSW). METHODS Two hundred and sixteen participants (MSM=116; MSW=100) who visited the Clinics Hospital of the School of the Medicine of the University of São Paulo completed two independent surveys (the BECK Depression Inventory and an adherence self-declared questionnaire) to evaluate their depression status and adherence to antiretroviral treatment, respectively. RESULTS The study highlighted a positive relationship between depression and low adherence to Highly Active Antiretroviral Therapy in these patients regardless of age and sexual orientation. In addition, MSM subjects were two times more prone than MSW subjects to develop depression symptoms. White or mixed race men showed 7.6 times greater adherence to treatment than black men. The probability of complete adherence to treatment was 3.8 times higher in non-depressed subjects than in depressed subjects regardless of their ethnicity. The chance of developing depression was 4.17 times higher for an individual with non-adherent behavior than for an adherent individual. CONCLUSIONS Individuals with low adherence rates have proportionally higher depression rates. Depressed men tend to show less adherence to treatment. Black but not mixed race or white men show less adherence to Highly Active Antiretroviral Therapy and have a greater chance of developing depression, which directly interferes with adherence. The chances of developing depression are four times greater for a patient with non-adherent behavior than for a patient with adherent behavior.

The current frame of reference on adherence to pharmacotherapy includes a set of behaviors experienced by the user, with observation of the detailed and continuous history of the use of each dose of the medication. Indicators based on pharmacy records have been used to measure adherence. The current review aimed to identify and describe indicators based on pharmacy records and to discuss their adequacy and limitations for measuring adherence. An exploratory literature review was conducted in three databases using the terms "adherence", "pharmacy records/administrative data", and "measure" to compose the descriptors for the selection of 81 articles and the elaboration of a chart with the denomination, sources, methods for calculation, description, and interpretation of the operational and referential meaning of 14 indicators. Given the most recent taxonomy for adherence proposed in the literature, we concluded that the indicators can be useful for identifying patients with medication-seeking behavior-related problems and analysis of persistence. The distance between supply-related events and difficulties in treatment follow-up can influence an analysis based exclusively on the use of these indicators.

Abstract
WHAT IS KNOWN AND OBJECTIVE The trajectory of HIV viral load and CD4 count and the occurrence of clinical events are primary considerations in the evaluation of antiretroviral therapy (ART) success or failure, yet a large number of studies do not describe these events from the point of therapy initiation. This study aims to describe the virological and immune response to ART and factors associated with immune and virological success in outpatients from a HIV/AIDS clinic in southern Brazil from therapy initiation. METHODS Longitudinal observational with ambidirectional data collection study with adult patients followed for at least 12 months after enrolment. Outcomes include (i) favourable immune response, defined as CD4 count ≥200 cells/mm³; and (ii) virological success, defined as viral load below the limit of detection (50 copies/mL). RESULTS The study included 332 patients, mostly men (63%), whose mean age was 40 (±10) years and with median family income of BR$ 490·00 per month (IQR: 350-875). Before starting ART, 43% of patients had indications of stable immune status (CD4 count ≥200 cells/mm³); the median CD4 count was 179 cells/mm³ (IQR: 93·5, 267) and increased to 379·5 cells/mm³ (IQR: 236·5, 591·3). The proportion of patients with CD4 count ≥200 cells/mm³ increased from 76% to 83%, and with undetectable viral load (UVL) increased from 51·7% to 73%. Factors associated with immune success at the end of study follow-up were as follows: female gender, pretreatment CD4 count ≥200 cells/mm³, previous UVL (measured when started prospective follow-up) and treatment with three drugs compared with ≥4. Factors associated with virological success were as follows: UVL (measured when started prospective follow-up) and use of three drugs compared with ≥4. WHAT IS NEW AND CONCLUSIONS Results of this study show that a large proportion (73%) of patients have rapid and successful immune and virological responses to ART and that factors which predict this response include starting ART early, whereas viral load is low and CD4 count is high, with fewer drugs. These results further support the ongoing need for ongoing programmes to increase early HIV testing, early linkage to and treatment with ART, and increased viral suppression.

Abstract
Objective To evaluate the accuracy of the PIMA point-of-care CD4 analyzer (PIMA) under field conditions in comparison to the current CD4 count system (FACSCalibur), and to evaluate the operational suitability and acceptability of health professionals (HP) and HIV-patients in using the PIMA in health clinics in the Amazon Region. Methods CD4 counts were measured onsite by the PIMA using fingerprick blood and in the reference laboratory by both the PIMA and FACSCalibur using venous blood. We used the Bland–Altman method to estimate the mean bias, and calculated the sensitivity and specificity at <200 and <500 cell/μL thresholds. Patients (n = 404) and HP (n = 7) were interviewed on the acceptability and operational suitability of the PIMA. Results Using fingerprick blood (n = 337), the PIMA showed a concordance correlation coefficient (Rc) of 0.81, mean difference of -111.9 cell/μL, 93.1%/98.5% sensitivity, and 89.2%/56.7% specificity at <200 and <500 cell/μL thresholds, respectively. Venous blood (n = 340) showed an Rc of 0.89, mean difference of -83.4 cell/μL, 98.3%/97.5% sensitivity, and 93.9%/66.0% specificity at <200 and <500 cell/μL thresholds, respectively. The capillary PIMA was well accepted and found operationally appropriate by patients and HP. Conclusions The agreement between both instruments was poor and the PIMA underestimated CD4 cell counts, which was more pronounced at CD4 counts ≥500 cell/μl. The PIMA’s performance with fingerprick blood was less reliable than its performance with venous blood. In Brazil, where antiretroviral treatment is initiated regardless of CD4 counts, the PIMA’s systematic bias towards CD4 underestimation may limit its role for monitoring HIV-patients.

Abstract
WHAT IS KNOWN AND OBJECTIVE Therapeutic success is characterized by undetectable viral load, immune reconstitution confirmed by CD4+ T-cell count and no clinical manifestations of disease. High treatment adherence is a major determinant of therapeutic success that needs prevention of viral replication, allowing immune reconstitution. Adherence to treatment <95% has been associated with both immune and viral failure. The objective of this study was to evaluate factors associated with therapeutic success in adult patients on highly active antiretroviral therapy (HAART) in a specialized centre for HIV-AIDS in southern Brazil, being defined therapeutic success as achieving and maintaining undetectable viral load, stable immune status (CD4+ T lymphocyte count ≥200 cells/mm(3) ) and adherence to HAART ≥ 95%. METHODS We conducted a historical cohort study nested in the PC-HIV randomized clinical trial of PC-HIV. We included adults who were on HAART at Pelotas HIV/AIDS Assistance Service between June 2006 and July 2007 and for whom information on treatment adherence, viral load and CD4+ cell count was available. Pregnant women were excluded. We obtained clinical data from medical records and socio-demographic information in an interview. Therapeutic success was defined as achieving and maintaining undetectable viral load, stable immune status (CD4+ T lymphocyte count ≥200 cells/mm(3) ) and adherence to HAART ≥95%. RESULTS AND DISCUSSION We included 136 patients (60% male) in the cohort study. Mean age was 40 ± 10 years, and median treatment duration was 59 months (IQR 25-93). Family income varied from 0 to 8 times the minimum wage (IQR 1·0-2·3). Therapeutic success was achieved by 90% (122 patients), and it was associated with previously undetectable viral load (PR = 1·30; 95% CI = 1·13-1·49) and treatment adherence prior to study entry (PR = 1·34; 95% CI = 1·07-1·69), independently of sex, age and previous immune status. WHAT IS NOW AND CONCLUSION When undetectable viral load, CD4+ cell count ≥200 cells/mm(3) and treatment adherence above 95% are included in the definition of therapeutic success, the rate was elevated (90%) and the factors associated were previous history of adherence to HAART and previous undetectable viral load.

Individual and contextual factors of influence on adherence to antiretrovirals among people attending public clinics in Rio de Janeiro, Brazil. BMC Public Health 2013; 13:574. [PMID: 23758780 PMCID: PMC3710472 DOI: 10.1186/1471-2458-13-574] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2012] [Accepted: 05/21/2013] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There are inconsistencies in the determinants of adherence to antiretrovirals (ARVs) across settings as well as a lack of studies that take into consideration factors beyond the individual level. This makes it necessary to examine factors holistically in multiple settings and populations while taking into consideration the particularities of each context, in order to understand the patterns of ARV adherence. This research explored ARV adherence and individual, relational and environmental-structural factors. METHODS A cross-sectional survey was conducted from August 2008 through July 2009 among participants currently on ARVs recruited from 6 public health clinics, selected to maximize diversity in terms of caseload and location, representing the range of clinics within Rio de Janeiro city, Brazil. Multivariate logistic regression analysis was used to assess the association between our multilevel factors with ARV adherence among participants with complete cases (n = 632). RESULTS Eighty-four percent of respondents reported adherence to all of their ARV doses in the last 4 days. Of the socio-demographic variables, those who had one child were positively associated with adherence (AOR 2.29 CI [1.33-3.94]). On the relational level, those with high social support (AOR 2.85 CI [1.50-5.41]) were positively associated with adherence to ARVs. On the environmental-structural level, we found gender was significant with women negatively associated with adherence to ARVs (AOR 0.58 CI [0.38-0.88]) while those with a high asset index (AOR 2.47 CI [1.79-3.40]) were positively associated with adherence to ARVs. CONCLUSIONS This research highlights the importance of examining the multiple levels of influence on ARV adherence. Intervention research in lower and middle-income settings should address and evaluate the impact of attending to both gender and economic inequalities to improve ARV adherence, as well as relational areas such as the provision of social support.

Abstract
This study aimed to evaluate adherence to antiretroviral treatment (ART) among HIV + adults, assess its association with HIV viral load (VL) and identify factors associated to adherence. A survey involving a random sample of adults followed at a HIV/AIDS reference center in São Paulo city, Brazil, from 2007 to 2009 was done. A questionnaire was applied and data were retrieved from the pharmacy and medical records. The study involved 292 subjects: 70.2% men; median age: 43 years; median duration of ART: 8 years. 89.3% self-reported taken all prescribed pills in the last 3 days but only 39.3% picked up ≥95% of the prescribed ART from the pharmacy in the last 12 months. At the multivariate analysis having symptoms prior to ART, taking fewer ART pills, and not missing medical appointments were independently associated to higher adherence. Adherence was strongly associated with undetectable HIV VL. Rates of undetectable HIV VL did not differ from 80 to ≥95% of adherence.

Abstract
The aim of this study was to evaluate the efficacy of the Portuguese version of the Medication Adherence Training Instrument (MATI) for improving adherence to antiretroviral therapy (ART) in southern Brazil. Two different follow-up modalities were compared in this 225 days randomized controlled study: one based on the MATI protocol and a conventional (non-MATI) clinical follow-up. There were no differences between the groups with the exception of socioeconomic class ( P < 0.005). The mean length of continuance in treatment was 111.4 (SD = 13.9) and 137.6 (SD = 17.3) days in the MATI and non-MATI groups, respectively. A Mantel–Cox log-rank test revealed no significant difference between the two interventions ( P = 0.34). Despite the sample size limitation, the results from this study indicate that the Portuguese version of the MATI was not more efficacious than the regular follow-up intervention for improving adherence of outpatients to ART.
