Risk-factors for non-adherence to antiretroviral therapy

Factors Associated With Antiretroviral Adherence Among Youth Living With HIV

BACKGROUND

Youth living with HIV (YLH) have an increased risk for psychosocial stressors that can affect their antiretroviral (ARV) adherence. We examined factors associated with self-reported ARV adherence among YLH ages 12-24 years old.

SETTING

YLH (N = 147) were recruited in Los Angeles, CA, and New Orleans, LA from 2017 to 2020.

METHODS

YLH whose self-reported recent (30 days) ARV adherence was "excellent" or "very good" were compared with nonadherent YLH on sociodemographic, clinical, and psychosocial factors using univariate and multivariate analyses.

RESULTS

Participants were predominantly male (88%), and 81% identified as gay, bisexual, transgender, queer, or other. The mean duration on ARV was 27 months (range 0-237 months). Most YLH (71.2%) self-reported being adherent, and 79% of those who self-reported adherence were also virally suppressed (<200 copies/mL). Multivariate analysis indicated being adherent was significantly associated with white race [aOR = 8.07, confidence intervals (CI): 1.45 to 74.0], Hispanic/Latinx ethnicity [aOR = 3.57, CI: 1.16 to 12.80], more social support [aOR = 1.11, CI: 1.05 to 1.18], and being on ARV for a shorter duration [aOR = 0.99, CI: 0.97 to 0.99]. Mental health symptoms, substance use, age, and history of homelessness or incarceration were unrelated to adherence.

CONCLUSIONS

Enhancing efforts to provide support for adherence to non-white youth, and those with limited social support and who have been on ARV treatment longer, may help increase viral suppression among YLH.

Adherence to antiretroviral therapy and factors associated with non-adherence: a cohort study at two referral services in Brazil

This cohort study evaluated non-adherence to antiretrovirals at referral services in Pernambuco, Brazil, 2016/2017, through self-report. A generalized mixed-effects model for binary outcomewas used. We assessed 542 participants with an adherence rate of 85.50%. A greater chance of non-adherence was associated with:a low/moderate level of nicotine dependence (OR = 2.79, p = 0.00, IC = 1.44-5.41); ≥7 tablets/day (OR = 6.14, p = 0.00, IC = 3.42-11.02); LPV/r (OR = 1.49, p = 0.6, IC = 0.98-2.26), ddI (OR = 3.34, p = 0.03, IC = 1.12-9.97), ABC (OR = 4.02, p = 0.05, IC = 1.01-16.03), RAL (OR = 2.49, p = 0.01, IC = 1.32-4.70) and DTG (OR = 4.65, p = 0.01, IC = 1.42-15.16); 6-10 year seropositive diagnosis (OR = 2.17, p = 0.01, IC = 1.20-3.92) and symptoms of depression (OR = 1.55, p = 0.03, IC = 1.03-2.33). Protective factors for non-adherence weres: ≥50 years (OR = 0.67, p = 0.06, IC = 0.45-1.01), secondary/higher education (OR = 0.48, p = 0.00, IC = 0.34-0.70), embarrassment at health service (OR = 0.49, p = 0.04, IC = 0.24-0.97), good understanding of antiretrovirals (OR = 0.62, p = 0.03, IC = 0.40-0.96), adverse event (OR = 0.74, p = 0,06, IC = 0.54-1.01), use of TDF (OR = 0.62, p = 0.01, IC = 0.43-0.90), NVP (OR = 0.41, p = 0.05, IC = 0.71-1.00) and EFZ (OR = 0.48, p = 0.01, IC = 0.29-0.80) and good knowledge of HIV/AIDS/ART. (OR = 0.67, p = 0.07, IC = 0.43-1.04). Variables with stronger association were those linked to ART. Systematic use of self-report adherence is recommended for priority groups.

Factors associated with anti-retroviral therapy adherence among patients living with HIV during the COVID-19 pandemic: A cross-sectional study

BACKGROUND

The coronavirus disease (COVID-19) pandemic causes fear and anxiety symptoms on some vulnerable populations such as patients living with human immunodeficiency virus (HIV) (PLWH). Physical distancing (during consultation in the clinic) and isolation restrictions will likely have a negative impact on/disruption to all care continuum services of HIV diseases although healthcare services and access to anti-retroviral therapy (ART) have continued to operate.

OBJECTIVE

To investigate the factors associated with ART adherence among PLWH during the COVID-19 pandemic.

METHODOLOGY

A cross-sectional study was conducted on 324 PLWH who had been on ART for at least 6 months between June 2020 and January 2021. A semi-structured questionnaire was used to interview participants to collect data on sociodemographic characteristics and other factors.

RESULTS

Of 324 PLWH taking ART, 264 (81.48%) had high adherence (≥95%) and 60 (18.52%) had low adherence (< 95%). Factors independently associated with high ART adherence were employment status (adjusted odds ratio (AOR): 0.030, 95% confidence interval (CI): 0.010-0.088; p < 0.001), type of antiretroviral (ARV) (AOR: 3.101, 95% CI: 1.137-8.456; p = 0.027), family support (AOR: 0.157, 95% CI: 0.052-0.475; p = 0.001), the perception that the COVID-19 pandemic negatively impacts the ability to attend clinics (AOR: 7.339, 95% CI: 1.46-36.79; p = 0.015), and the perception that the COVID-19 pandemic negatively impacts the ability to take ART (AOR: 10.611, 95% CI: 2.98-37.72; p < 0.001).

CONCLUSIONS

During the COVID-19 pandemic, factors associated with high ART adherence among PLWH attending the Hospital of Wangaya in Denpasar, Bali, Indonesia were employment status, ART type [non-fixed dose combination (FDC)], family support, and the perception that the COVID-19 pandemic negatively impacts the ability to attend clinics and to take ART.

Factors Associated With Adherence To Anti-Retroviral Therapy Among People Living With HIV/AIDS At Wangaya Hospital In Denpasar, Bali, Indonesia: A Cross-Sectional Study

Background

Acquired Immunodeficiency Syndrome (AIDS) is a major public health problem. Recently AIDS was considered as a manageable chronic disease. High adherence to Anti-Retroviral Therapy (ART) is necessary to achieve undetectable viral load, reduce morbidity, mortality and to improve the quality of life. It is also preventing the drug resistance, reducing the transmission and finally leading to live longer and healthier.

Objectives

To assess the factor associated with ART adherence among people living with HIV/AIDS (PLWHA) at Wangaya Hospital, in Denpasar, Bali, Indonesia.

Methodology

A cross-sectional study was carried out during January 2015–December 2017 among 202 PLWHA taking ART for at least 6 months. The participants were interviewed using a semi-structured questionnaire to obtain data on socio-demographic characteristics. The data were analyzed using SPSS software for windows version 24.0. Chi-square test was done, the precision value of 95% (p<0.05) was considered statistically to be significant.

Results

A total of 202 PLWHA taking ART, 170 (84.16%) were reported with high adherence (≥95%), 32 (15.84%) were low adherence (<95%). Factors found to be independently associated with high adherence to ART were employment status/occupation (p = 0.011), type of ARV (due to adverse effect of ART) (p = 0.002) and family support (p < 0.001).

Conclusion

This study found that the factor associated with ART adherence among PLWHA who visited Wangaya Hospital, in Denpasar, Bali, Indonesia, was employment status, type of ARV and family support.

Drug-drug interactions and clinical considerations with co-administration of antiretrovirals and psychotropic drugs

Psychotropic medications are frequently co-prescribed with antiretroviral therapy (ART), owing to a high prevalence of psychiatric illness within the population living with HIV, as well as a 7-fold increased risk of HIV infection among patients with psychiatric illness. While ART has been notoriously associated with a multitude of pharmacokinetic drug interactions involving the cytochrome P450 enzyme system, the magnitude and clinical impact of these interactions with psychotropics may range from negligible effects on plasma concentrations to life-threatening torsades de pointes or respiratory depression. This comprehensive review summarizes the currently available information regarding drug-drug interactions between antiretrovirals and pharmacologic agents utilized in the treatment of psychiatric disorders-antidepressants, stimulants, antipsychotics, anxiolytics, mood stabilizers, and treatments for opioid use disorder and alcohol use disorder-and provides recommendations for their management. Additionally, overlapping toxicities between antiretrovirals and the psychotropic classes are highlighted. Knowledge of the interaction and adverse effect potential of specific antiretrovirals and psychotropics will allow clinicians to make informed prescribing decisions to better promote the health and wellness of this high-risk population.

Symptomatic profile of infected individuals with HIV/AIDS in a physiotherapy department

Abstract Introduction Changes in the profile of infected individuals with HIV and the chronicity of this condition become necessary a better understanding about the clinical changes caused by the disease. Objective This study characterizes the physical symptoms of infected individuals with HIV in a physiotherapy department of a specialized HIV treatment center. Methods A descriptive study with quantitative analysis was performed. All registered users in the physiotherapy department (138 individuals) from 2009 to 2013 were included. Data analysis considered absolute and relative frequencies of the variables of interest. Results Most patients were female (55%) and the mean age was 35.0 years (± 16.8). Most users were usingantiretroviral therapy and had 4 to 10 years (51.8%) of the HIV diagnosis. Many patients have comorbidities and the most prevalent was cerebral toxoplasmosis. The most common physical complaints were hemiparesis, pain, alteration in muscle tone and lipodystrophy. Conclusion According the symptomatic profile found, expanding the role of physiotherapists for infected individuals with HIV is necessary, since the physiotherapy has a wide range of preventive and therapeutic interventions that can increase functionality, independence level and social participation.

Risk factors associated with sexually transmitted infections among HIV infected men who have sex with men

To investigate the factors associated with sexually transmitted infection and Human Immunodeficiency Virus (STI-HIV) co-infection among men who have sex with men (MSM). A total of 357 HIV-infected participants (84 STI-HIV co-infection and 273 HIV infections only) were recruited from Jiangsu, China. Logistic regression analyses were used to estimate the related factors associated with STI-HIV co-infection. Marginal structural models were adopted to estimate the effect of transmission drug resistance (TDR) on STI-HIV co-infection. For all participants, logistic regression analyses revealed that those who diagnosed with HIV-1 for longer duration (≥1.8 years) were significantly associated with reduced STI-HIV co-infection risk (OR = 0.55, 95%CI: 0.32–0.96, P = 0.036). In further stratification analysis by antiretroviral therapy (ART), individuals with longer duration showed consistent significant associations with STI-HIV co-infection risk (OR = 0.46, 95%CI: 0.26–0.83, P = 0.010) among MSM with ART-naïve status. In addition, significant reduced risk for STI-HIV co-infection (OR = 0.98, 95%CI: 0.96–0.99, P = 0.010) were observed in younger (under the average age of 31.03) MSM of the same group. Interestingly, we also found TDR was significantly associated with an increased risk of STI-HIV co-infection risk (OR = 3.84, 95%CI: 1.05–14.03, P = 0.042) in ART-naïve group. Our study highlights a pattern of STI-HIV co-infection among MSM in China and indicates that targeted interventions aimed at encouraging TDR monitoring in MSM with early HIV infection are warranted.

Factors associated with non-adherence to antiretroviral therapy in adults with AIDS in the first six months of treatment in Salvador, Bahia State, Brazil

The control of viral replication is essential in the highly active antiretroviral therapy (HAART), and adherence to therapy is instrumental for such control. Individual and external factors influence adhesion to the use of antiretroviral (ARV) drugs. This is a cross-sectional study to investigate factors associated with non-adherence to HAART in AIDS patients in Salvador, Bahia State, Brazil, with age ≥ 13 years and first prescription in 2009. Data was collected from patient charts and pharmacy records. From a total of 216 patients, 65.3% were males; mean age 37.8 ± 9.5 years; single, 67.9%; heterosexual, 64%; more than 8 years of school education, 65.3%; alcohol users, 61.5%; non-smokers, 75,1% or non-illicit drug users, 93.7%. A proportion of 94% started ARV therapy with TCD4+ < 350 cells/mm3; 61.8% were symptomatic; and 68.4% had an adverse drug reaction. The prevalence of non-adherence was 25%. The variables associated were: longer time between HIV infection and AIDS (aOR = 3.9), adverse drug reaction (aOR = 2.4), under 34 years of age (aOR = 2.2), less than 8 years of school education (aOR = 2.2) and illicit drugs use (aOR = 2.6). A high-non-adherence rate is an important problem within the first six months of HAART.

Predictors and correlates of adherence to combination antiretroviral therapy (ART) for chronic HIV infection: a meta-analysis

BACKGROUND

Adherence to combination antiretroviral therapy (ART) is a key predictor of the success of human immunodeficiency virus (HIV) treatment, and is potentially amenable to intervention. Insight into predictors or correlates of non-adherence to ART may help guide targets for the development of adherence-enhancing interventions. Our objective was to review evidence on predictors/correlates of adherence to ART, and to aggregate findings into quantitative estimates of their impact on adherence.

METHODS

We searched PubMed for original English-language papers, published between 1996 and June 2014, and the reference lists of all relevant articles found. Studies reporting on predictors/correlates of adherence of adults prescribed ART for chronic HIV infection were included without restriction to adherence assessment method, study design or geographical location. Two researchers independently extracted the data from the same papers. Random effects models with inverse variance weights were used to aggregate findings into pooled effects estimates with 95% confidence intervals. The standardized mean difference (SMD) was used as the common effect size. The impact of study design features (adherence assessment method, study design, and the United Nations Human Development Index (HDI) of the country in which the study was set) was investigated using categorical mixed effects meta-regression.

RESULTS

In total, 207 studies were included. The following predictors/correlates were most strongly associated with adherence: adherence self-efficacy (SMD = 0.603, P = 0.001), current substance use (SMD = -0.395, P = 0.001), concerns about ART (SMD = -0.388, P = 0.001), beliefs about the necessity/utility of ART (SMD = 0.357, P = 0.001), trust/satisfaction with the HIV care provider (SMD = 0.377, P = 0.001), depressive symptoms (SMD = -0.305, P = 0.001), stigma about HIV (SMD = -0.282, P = 0.001), and social support (SMD = 0.237, P = 0.001). Smaller but significant associations were observed for the following being prescribed a protease inhibitor-containing regimen (SMD = -0.196, P = 0.001), daily dosing frequency (SMD = -0.193, P = 0.001), financial constraints (SMD -0.187, P = 0.001) and pill burden (SMD = -0.124, P = 0.001). Higher trust/satisfaction with the HIV care provider, a lower daily dosing frequency, and fewer depressive symptoms were more strongly related with higher adherence in low and medium HDI countries than in high HDI countries.

CONCLUSIONS

These findings suggest that adherence-enhancing interventions should particularly target psychological factors such as self-efficacy and concerns/beliefs about the efficacy and safety of ART. Moreover, these findings suggest that simplification of regimens might have smaller but significant effects.

Association between smoking, crack cocaine abuse and the discontinuation of combination antiretroviral therapy in Recife, Pernambuco, Brazil

Despite the effectiveness of combination antiretroviral therapy in the treatment of people living with HIV/AIDS (PLWHA), nonadherence to medication has become a major threat to its effectiveness. This study aimed to estimate the prevalence of self-reported irregular use of antiretroviral therapy and the factors associated with such an irregularity in PLWHA. A cross-sectional study of PLWHA who attended two referral centers in the city of Recife, in Northeastern Brazil, between June 2007 and October 2009 was carried out. The study analyzed socioeconomic factors, social service support and personal habits associated with nonadherence to antiretroviral therapy, adjusted by multivariable logistic regression analysis. The prevalence of PLWHA who reported irregular use of combination antiretroviral therapy (cART) was 25.7%. In the final multivariate model, the irregular use of cART was associated with the following variables: being aged less than 40 years (OR = 1.66, 95%-CI: 1.29-2.13), current smokers (OR = 1.76, 95%-CI: 1.31-2.37) or former smokers (OR = 1.43, 95%-CI: 1.05-1.95), and crack cocaine users (OR = 2.79, 95%-CI: 1.24-6.32). Special measures should be directed towards each of the following groups: individuals aged less than 40 years, smokers, former smokers and crack cocaine users. Measures for giving up smoking and crack cocaine should be incorporated into HIV-control programs in order to promote greater adherence to antiretroviral drugs and thus improve the quality of life and prolong life expectancy.

Quality of life and adherence to antiretroviral therapy in Southern Brazil

The absence of or limited adherence to treatment is the main cause for the failure of Highly Active Antiretroviral Therapy (HAART). In Brazil, adherence to antiretroviral therapy has been lower than the recommended levels. Although HAART may produce adverse reactions, failure to comply with it may aggravate patients' health status and impair Quality of Life (QoL). The QoL of individuals living chronically with HIV and AIDS has been considered one of the main treatment outcomes. This study is part of a 225-day prospective trial in which participants were enrolled in two different modalities of follow-up: the usual model medical follow-up or an intervention based on the Medication Adherence Training Instrument (MATI). The WHOQOL-HIV BREF questionnaire was used to evaluate QoL of research participants in both groups on the 15th and 225th days of follow-up after the baseline assessment. The result of this study revealed no significant differences of WHOQOL-HIV BREF scores between participants allocated to MATI and non-MATI groups in the first assessment. However, there was a significant difference between the scores obtained on the 15th and 225th days in the domain related to spirituality and personal beliefs irrespective of the modality of follow-up. Other domains of the WHOQOL-HOV BREF remained unchanged. These results indicate that, in this sample, personal beliefs and spirituality may be relevant subjects to explain sustained levels of adherence to HAART.

Impact of use of alcohol and illicit drugs by AIDS patients on adherence to antiretroviral therapy in Bahia, Brazil

Use of alcohol and illicit drugs is a common finding among HIV-infected individuals, but there are many open questions about its impact on adherence to antiretroviral therapy and virological outcomes. Our study aimed to evaluate the impact of the use of alcohol and illicit drugs on the adherence to antiretroviral therapy (ART) among patients starting ART in Salvador, Brazil. We followed up 144 AIDS patients initiating ART for a 6-month period. At baseline, they were interviewed about demographics, behavior, and use of illicit drugs and alcohol. All of them had HIV-1 RNA plasma viral load and CD4(+)/CD8(+) cells count measured before starting therapy. After 60 days of treatment they were asked to answer a new questionnaire on adherence to ART. All patients were monitored during the following months, and new CD4(+) cell count/HIV-1 RNA plasma viral load determinations were performed after 6 months of therapy. Optimal adherence to therapy was defined by self-reported questionnaire, by 95% use of prescribed drug doses, and by using plasma HIV-1 RNA viral load as a biological marker. A total of 61 (42.4%) patients reported alcohol use, 7 (4.9%) used illicit drugs, and 17 (11.8%) used both alcohol and illicit drugs. Being in a steady relationship was protective to nonadherence (95% CI: 0.18-0.84). Missing more than two medical visits was also associated with a 68% higher likelihood of nonadherence (95% CI: 0.10-1.02). After logistic regression we detected a higher risk of nonadherence for patients declaring use of alcohol plus illicit drugs (odds ratio=6.0; 95% CI: 1.78-20.28) or high-intensity use of alcohol (odds ratio=3.29; 95% CI: 1.83-5.92). AIDS patients using alcohol and/or illicit drugs are socially vulnerable, and need specific and flexible programs, combining mental health care, harm reduction strategies, and assisted drug therapy to maximize the chances of successful use of ART.

A randomized controlled trial of a protocol of interviews designed to improve adherence to antiretroviral medications in southern Brazil

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.

Substance use: impact on adherence and HIV medical treatment

Substance use is highly prevalent among people living with HIV/AIDS, is often comorbid with other mental health problems, related to poor HIV medical outcomes, and, is associated with poor medication and treatment adherence. The current review reports on the recent state of the literature in terms of substance use and its relation to HIV medication and treatment adherence, and offers recommendations for advancing treatment and secondary HIV prevention efforts. Identifying substance users within HIV primary care and developing, evaluating, and refining integrative substance use-mental health-adherence interventions may be clinically important targets for effective disease management and may contribute to secondary HIV prevention efforts.

Barreiras e aspectos facilitadores da adesão à terapia antirretroviral em Belo Horizonte-MG

O objetivo desse estudo foi conhecer dificuldades e aspectos que facilitam a adesão à terapia antirretroviral (TARV) por pessoas com HIV/AIDS. Estudo qualitativo, desenvolvido junto a 26 sujeitos em uso de TARV, acompanhados por serviço de referência em Belo Horizonte, Minas Gerais. A análise das entrevistas, no que se refere às dificuldades encontradas, resultou em categorias relativas ao cotidiano de vida, às representações sobre o HIV e à complexidade do tratamento. Quanto aos aspectos facilitadores, as categorias encontradas foram a ausência de efeitos colaterais, lembrança dos sintomas da doença, aumento da sobrevida e influência da rede social. Os resultados mostram a importância de acompanhamento efetivo dos profissionais dos serviços para construírem, junto com os sujeitos, estratégias que melhorem a adesão à TARV.

Medication adherence mediates the relationship between marital status and cardiac event-free survival in patients with heart failure

OBJECTIVE

Prognosis is worse in unmarried patients compared with married patients with heart failure (HF). The reasons for differences in outcomes are unclear, but variations in medication adherence may play a role, because medication adherence is essential to achieving better outcomes. The study objective was to determine whether medication adherence mediated the relationship between marital status and cardiac event-free survival in patients with HF.

METHODS

Demographic, clinical, and psychosocial data were collected by questionnaires and medical record review for 136 patients with HF (aged 61 ± 11 years, 70% were male, 60% were in New York Heart Association class III/IV). Medication adherence was monitored objectively for 3 months using the Medication Event Monitoring System. Cardiac event-free survival data were obtained by patient/family interview, hospital database, and death certificate review. A series of regression and Cox survival analyses were performed to determine whether medication adherence mediated the relationship between marital status and event-free survival.

RESULTS

Cardiac event-free survival was worse in unmarried patients than in married patients. Unmarried patients were more likely to be nonadherent and 2 times more likely to experience an event than married patients (P = .017). Marital status was not a significant predictor of event-free survival after entering medication adherence in the model, demonstrating a mediation effect of adherence on the relationship of marital status to survival.

CONCLUSION

Medication adherence mediated the relationship between marital status and event-free survival. It is important to design interventions to increase medication adherence that take into account subgroups, such as unmarried patients, who are at higher risk for nonadherence.

Effect of caregivers' depression and alcohol use on child antiretroviral adherence in South Africa

Pediatric antiretroviral adherence is difficult to assess, and subjective measures are affected by reporting bias, which in turn may depend on psychosocial factors such as alcohol use and depression. We enrolled 56 child-caregiver dyads from Cape Town, South Africa and followed their adherence over 1 month via various methods. The Alcohol Use Disorder Inventory Tool and Beck Depression Inventory 1 were used to assess these factors and their affect on pediatric adherence. The median age of the children was 4 years, and median time on antiretrovirals was 20 months. Increased time on ART was associated with poorer adherence via 3-day recall (3DR; p=0.03). Ethanol use was inversely associated with adherence by both subjective measures, 3DR and visual analogue scale (VAS) (both p<0.01), and with Medication Event Monitoring System (MEMS) adherence as a continuous variable. In a multivariate analysis predicting MEMS adherence greater than 95%, including variables that were associated with adherence in univariate analyses, having a mother as a caregiver and shorter time on highly active antiretroviral therapy (HAART) were significantly associated with adherence (odds ratio [OR] 19.2; 95% confidence interval [CI] 1.1-327 and 0.9; 95% CI 0.9-0.99). Pediatric adherence is affected by caregiver alcohol use, but caregiver relationship to the child is most important. This small study suggests that interventions should aim to keep mothers healthy and alive, as well as alcohol-free.

Livelihood security and adherence to antiretroviral therapy in low and middle income settings: a systematic review

INTRODUCTION

We sought to examine the association between livelihood security and adherence to antiretroviral therapy (ARVs) in low- and middle-income countries (LIMC).

METHODS

Performing a systematic review, we searched, independently and in duplicate, 7 electronic databases and 2 conference websites for quantitative surveys that examined the association between indicators of livelihood security and adherence to ARVs in LIMC between 2000-2010. Criteria for relevance were applied to complete papers (quantitative study with estimates of associations) and quality assessment was conducted on those deemed relevant. We performed three regressions to measure the association between each type of livelihood and adherence.

RESULTS

Twenty original studies and 6 conference abstracts were included, the majority from Africa (n = 16). Seventeen studies and 3 conference abstracts were cross-sectional and 3 studies and 3 abstracts were prospective clinical cohort studies, with considerable variation in quality for studies of each design type. Among the diverse populations represented, we observed considerable variation in associations between measurements of livelihood indicators and increasingly accepted adherence measures, irrespective of study design or quality. A financial capital indicator, financial constraints/payment for ARV medication, was more commonly associated with non-adherence (3/5 studies). A human capital indicator, educational level, was most commonly associated with adherence (11/20 studies).

DISCUSSION

Additional better quality research examining livelihood security is required to inform provision of optimal supports for adherence and mitigation of the impacts of HIV/AIDS.

[Compliance with the treatment by patients with the co-infection HIV/tuberculosis: integrative literature review]

This is an integrative review whose objective was to evaluate the evidences available in the literature about the factors associated to the compliance with the treatment by patients with the co-infection HIV/TB. Articles published in the period from 2002 to 2008, in the databases LILACS and MEDLINE were analyzed. The material was categorized according to the year of publication, periodical, study location and factors related to the compliance. The final sample included eight articles. The factors found, associated to the compliance with the treatment of the co-infection HIV/TB, related to: the individual and his lifestyle (previous TB treatment, fear of stigma and discrimination, use of chemical substances, depression, social support); the disease and the medication (type of medication regime, use of other medication, adverse effects, difficulty to diagnose TB in these patients); and the health services (operational problems to follow up the treatment, training of the professionals, supervision, different locations to treat TB and HIV).

Monitoring adherence to antiretroviral treatment in Brazil: an urgent challenge

The aim of this study was to describe the effect of non-adherence on the main laboratory outcomes, TCD4+ lymphocyte count and viral load, routinely used to monitor patients initiating treatment according to three different approaches to measure adherence to antiretroviral therapy. Among 288 participants, 22.9%, 31.9% and 74.3% were considered non-adherent, according to medical charts, self-report and pharmacy records, respectively. Depending on the adherence measures used, the average gain in TCD4+ lymphocyte count ranged from 142.4 to 195.4 cells/mm3 among adherent patients, and from 58.5 to 99.8 lymphocytes TCD4+/mm3 among those non-adherent. The average reduction on viral load ranged from 4.25 to 4.62 log copies/mL among the adherent patients, and from 1.99 to 4.07 log among those non-adherent. Monitoring antiretroviral adherence should be considered a priority in these public AIDS referral centers in order to identify patients at high risk of developing virologic failure. Early interventions are necessary in order to maintain the initial therapeutic regimens for longer periods.
