Non-adherence to anti-retroviral therapy among HIV infected adults in Mon State of Myanmar

Experiences of patients living with HIV and AIDS on antiretroviral therapy in Accra, Ghana

BACKGROUND

 The human immunodeficiency virus and acquired immunodeficiency syndrome (HIV and AIDS) pandemic has greatly affected Africa, particularly Ghana. The pandemic remains a public health concern, particularly in terms of accessing essential medication and improving quality of life for people living with the disease.

OBJECTIVES

 This study aimed to explore and describe the experiences of persons diagnosed and living with HIV who are on antiretroviral therapy.

METHOD

 A qualitative, exploratory, descriptive, and contextual design was used. The research population included persons diagnosed with HIV who were receiving antiretroviral therapy at three public hospitals in Ghana. Data saturation was achieved after conducting 15 semi-structured interviews. Creswell's six steps of data analysis were used to analyse the data, which resulted in the emergence of one main theme and six sub-themes.

RESULTS

 The main theme identified by the researchers highlighted the participants' diverse experiences of being diagnosed and living with HIV. It was found that the study participants expressed shock, disbelief, surprise, and fear of death after being diagnosed with HIV. The participants also experienced stigmatisation, discrimination, and rejection.

CONCLUSION

 There is a need for further research on the extent of discrimination and stigmatisation and the effect on optimal adherence to antiretroviral therapy. Continuous public education on HIV is required to limit the extent of discrimination and stigmatisation.Contribution: The study has highlighted the various emotions related to stigma and discrimination expressed by persons living with HIV (PLHIV). The findings will guide policy on eliminating discrimination and stigmatisation for people living with HIV.

Opening the door on entry inhibitors in HIV: Redefining the use of entry inhibitors in heavily treatment experienced and treatment-limited individuals living with HIV

INTRODUCTION

Entry inhibitors are a relatively new class of antiretroviral therapy and are typically indicated in heavily treatment experienced individuals living with HIV. Despite this, there is no formal definition of 'heavily treatment experienced'. Interpretation of this term generally includes acknowledgement of multidrug resistance and reflects the fact that patients in need of further treatment options may have experienced multiple lines of therapy. However, it fails to recognize treatment limiting factors including contraindications, age-associated comorbidities, and difficulty adhering to regimens.

METHODS

This manuscript follows a roundtable discussion and aims to identify the unmet needs of those living with HIV who are in need of further treatment options, to broaden the definition of heavily treatment experienced and to clarify the use of newer agents, with an emphasis on the potential role of entry inhibitors, in this population.

RESULTS/CONCLUSIONS

Within the entry inhibitor class, mechanisms of action differ between agents; resistance to one subclass does not confer resistance to others. Combinations of entry inhibitors should be considered in the same regimen, and if lack of response is seen to one entry inhibitor another can be tried. When selecting an entry inhibitor, physicians should account for patient preferences and needs as well as agent-specific clinical characteristics. Absence of documented multidrug resistance should not exclude an individual from treatment with an entry inhibitor; entry inhibitors are a valuable treatment option for all individuals who are treatment limited or treatment exhausted. We should advocate for additional clinical trials that help define the role of entry inhibitors in people with exhausted/limited ART options other than drug resistance.

Effects of psychosocial factors on nonadherence to ART in Ganta, Nimba county, Liberia

Background

It has been widely noted that lifetime adherence to antiretroviral therapy (ART) is necessary for HIV treatment outcome; however, retention on ART among people living with HIV (PLWH) remains a great challenge to achieve the Global AIDS Strategy: End inequalities, End AIDS. Nonadherence to ART is one of the HIV care problem in Liberia despite the availability of free ART. Psychosocial factors, i.e., perceived stigma and social support likely contributed to nonadherence to ART. We investigated associations among clinical factors, psychosocial factors, and nonadherence to ART.

Methods

A community-based cross-sectional study was conducted among 185 PLWH, age ≥ 18 years receiving ART in Ganta, Nimba county, Liberia at least 3 months. The structured questionnaire was used to collect data from April to May 2020. Associated factors of nonadherence to ART were identified using multivariable binary logistic regression, and the p-value < 0.05 was considered statistically significant.

Results

Of 185 respondents, 62.2% showed nonadherence to ART. Females reported higher nonadherence compared with males (64.4% vs. 56.6%). Multivariable binary logistic regression revealed strong experiences of stigma (PORadj = 2.392, p-value = 0.018), poor information support (PORadj = 2.102, p-value = 0.026) increased prevalence of ART nonadherence among Liberian PLWH.

Conclusions

The healthcare providers may apply interventions to reduce perceived stigma and to enhance continuous information provision in addition to support from health care providers and family members. An intensive monitoring of ART side effects is needed to be strengthened in particular among newly started ART patients.

Validation and Clinical Application of a Liquid Chromatography-Ultraviolet Detection Method to Quantify Dolutegravir in Dried Blood Spots

BACKGROUND

Dolutegravir is currently the preferred component of first-line antiretroviral therapy. To facilitate clinical pharmacology studies in key populations, quantitative analytical methods compatible with microsampling and adaptable to resource-limited settings are desirable. The authors developed and validated a liquid chromatography-ultraviolet detection method to quantify dolutegravir in dried blood spots (DBS).

METHODS

Calibration standards and quality control samples were prepared by spotting 50 μL of dolutegravir-spiked whole blood on each circle of DBS cards. Three spots (two 6-mm punches/spot) were extracted with methanol. Chromatographic separation was achieved with gradient elution of acetonitrile/potassium phosphate monobasic buffer (pH 5) on a reverse-phase C18 column (flow rate, 1 mL/min) using pioglitazone as the internal standard. UV detection was performed at 260 nm. In the clinical pharmacokinetic study, DBS from finger prick was collected from participants (n = 10) at 8 time points over 12 hours postdosing, with paired plasma at 1 and 12 hours. The method was used to quantify dolutegravir, estimating pharmacokinetic parameters. Agreement between DBS and plasma concentrations was evaluated using linearity and Bland-Altman plots.

RESULTS

The method was validated over the concentration range of 0.4-10 mcg/mL, accuracy was 102.4%-114.8%, and precision was 3.4%-14.7%. The mean recovery was 42.3% (%CV: 8.3). The mean (±SD) dolutegravir concentration in DBS was 37.5% (±3.8%) lower than that in the plasma. DBS-derived and measured plasma concentrations showed strong correlation with linearity (R2 = 0.9804) and Bland-Altman plots. Means (%CV) of area under curve, Cmax, and C24 from the DBS-derived plasma concentration were 37.8 (23.2) mcg·h/mL, 2.7 (24.7) mcg/mL, and 1.34 (31.6) mcg/mL, respectively.

CONCLUSIONS

The application of this simple, accurate, and precise method will expand opportunities for clinical assessment of dolutegravir in resource-limited settings.

Integrative literature review of evidence-based guidelines on antiretroviral therapy adherence among adult persons living with HIV

AIM

To summarize recommendations from available evidence-based guidelines that enhance, address or guide antiretroviral therapy adherence among adult persons living with human immunodeficiency virus.

DESIGN

An integrative literature review approach.

DATA SOURCE

Guidelines were accessed through Google from the databases of the Canadian Medical Association InfoBase clinical practice database, National Guidelines Clearinghouse, Writer's Guidelines database, the National Institute for Health and Clinical Excellence, UNICEF and WHO. Databases such as PubMed, Google Scholar, EBSCOhost (CINAHL, ERIC, Academic search complete, E-journals, Psych Info and MEDLINE), EMERALD INSIGHT, JSTOR, SCIENCE DIRECT and FINDPLUS were also searched, followed by a citation search. Data sources were searched between 1996 and January 2022.

REVIEW METHODS

The five steps of the integrative literature review process, as described by Whittemore and Knafl, were used. These steps are as follows: step one; problem identification, step two; literature search, step three; data evaluation; step four: data analysis and the final step was data presentation.

RESULTS

Sixteen guidelines related to antiretroviral therapy adherence were included for data extraction and synthesis. The findings revealed two themes as follows: theme 1: monitoring antiretroviral therapy adherence and theme 2: interventions to promote antiretroviral therapy adherence related to education and counselling, adherence tools, health service delivery and antiretroviral strategies.

CONCLUSION

Antiretroviral therapy adherence in adult persons requires both interventions as well as monitoring. The various contributing factors relating to antiretroviral therapy adherence should be further explored.

IMPACT

Evidence from the included guidelines can assist nurses in promoting a person's adherence to antiretroviral treatment, which could improve their health and well-being.

Stigma Determines Antiretroviral Adherence in Adults With HIV in Myanmar

INTRODUCTION

Understanding social and structural barriers that determine antiretroviral therapy (ART) adherence can improve care. Assessment of such factors is limited in Myanmar, a country with high HIV prevalence and increasing number of people living with HIV initiating ART.

METHODS

Questionnaires were administered to adults with HIV across 4 Myanmar cities to estimate adherence and its potential determinants, including HIV knowledge, social support, barriers to care, enacted and internalized stigma, and engagement in peer-to-peer HIV counseling (PC). Associations were determined using logistic mixed-effects modeling.

RESULTS

Among 956 participants, the mean age was 39 years, 52% were female, 36% had CD4 <350 cells/mm3, and 50% received pre-ART PC. Good adherence was reported by 74% of participants who had better HIV knowledge than those reporting nonadherence. Among nonadherent, 44% were forgetful and 81% were careless about taking ART. Among all participants, most (53%) were very satisfied with their social support and 79% reported lack of financial resources as barriers to care. Participants most frequently reported being viewed differently by others (30%) and feeling as if they were paying for past karma or sins because of their HIV diagnosis (66%). Enacted stigma (odds ratio 0.86; 95% confidence interval 0.79 to 0.92, P < 0.01) and internalized stigma (odds ratio 0.73; 95% confidence interval: 0.56 to 0.95, P = 0.023) were associated with worse adherence.

CONCLUSIONS

Increased self-reported ART adherence in Myanmar is associated with less enacted and internalized stigma. These findings suggest the benefit of developing and promoting adherence interventions, which are focused on mitigating HIV-related stigma in the county.

Adaptation and validation of a culturally adapted HIV stigma scale in Myanmar

BACKGROUND

HIV stigma is a common barrier to HIV prevention, testing, and treatment adherence, especially for low- and middle-income countries such as Myanmar. However, there was no validated Myanmar version of a stigma scale. Therefore, we adapted the English version of the 40-item Berger's HIV stigma scale and the 7-item Indian HIV stigma scale into a 47-item Myanmar HIV stigma scale and then evaluated the scale's psychometric properties.

METHOD

From January 2020 to May 2020, using random sampling methods, 216 eligible Myanmar people living with HIV/AIDS (PLWHA) were contacted from a closed Facebook group that included more than 10,000 PLWHA. A sample of 156 Myanmar PLWHA completed the online self-reported survey.

RESULTS

A six-factor structure for the scale was determined through exploratory factor analysis, explaining 68.23% of the total variance. After deleting 12 items, the 35-item HIV stigma scale achieved Cronbach 's α of 0.72 to 0.95. Construct validity of the scale was demonstrated by significant association with self-reported depression and social support levels (r = 0.60, and - 0.77, p < 0.01). In Rasch analysis, the scale achieved person reliability of 3.40 and 1.53 and a separation index of 0.92 and 0.70. The infit and outfit mean squares for each item ranged from 0.68 to 1.40. No differential item functioning across gender or educational level was found.

CONCLUSIONS

The psychometric properties of the 35-item Myanmar version of the HIV stigma scale support it as a measure of stigma among PLWHA in Myanmar. This instrument could help healthcare providers to better understand how stigma operates in PLWHA and to develop tailored stigma-reduction interventions in Myanmar.

Assessing depressive symptoms among people living with HIV in Yangon city, Myanmar: Does being a member of self-help group matter?

Background

While self-help groups have been formed among people living with HIV, few studies have been conducted to assess the role of self-help groups in mitigating depressive symptoms. This study investigated the association between self-help group membership and depressive symptoms among people living with HIV in Yangon, Myanmar.

Methods

In this cross-sectional study, data were collected from people living with HIV at three antiretroviral therapy clinics in 2017. Multiple logistic regression analyses were carried out to examine the associations between having self-help group membership and depressive symptoms. Three ART clinics were purposively selected based on the recommendation from the National AIDS Program in Myanmar. At these clinics, people living with HIV were recruited by a convenience sampling method.

Results

Among people living with HIV recruited in this study (n = 464), 201 (43.3%) were members of a self-help group. The membership was not associated with having depressive symptoms (adjusted odds ratio [AOR] 1.59, 95% confidence interval [CI] 0.98–2.59). Factors associated with having depressive symptoms were female (AOR 3.70, 95% CI 1.54–8.88) and lack of social support (AOR 0.97, 95% CI 0.96–0.98) among self-help group members, and female (AOR 3.47, 95% CI 1.70–7.09), lack of social support (AOR 0.98, 95% CI 0.97–0.99), and internalized stigma (AOR 1.28, 95% 1.08–1.53) among non-members.

Conclusions

This study did not find evidence on the association between membership in self-help groups and depressive symptoms among people living with HIV. Social support was a protective factor against depressive symptoms both self-help group members and non-members, although the level of social support was lower among members than non-members. The activities of self-help groups and care provided by the ART clinics should be strengthened to address mental health problems among people living with HIV in the study site.

An update on drug-drug interactions between antiretroviral therapies and drugs of abuse in HIV systems

INTRODUCTION

While considerable progress has been made in the fight against HIV/AIDS, to date there has not been a cure, and millions of people around the world are currently living with HIV/AIDS. People living with HIV/AIDS have substance abuse disorders at higher rates than non-infected individuals, which puts them at an increased risk of drug-drug interactions.

AREAS COVERED

Potential drug-drug interactions are reviewed for a variety of potential drugs of abuse, both licit and illicit. These drugs include alcohol, cigarettes or other nicotine delivery systems, methamphetamine, cocaine, opioids, and marijuana. Potential interactions include decreased adherence, modulation of drug transporters, or modulation of metabolic enzymes. We also review the relative incidence of the use of these drugs of abuse in People living with HIV/AIDS.

EXPERT OPINION

Despite considerable improvements in outcomes, disparities in outcomes between PLWHA who use drugs of abuse, vs those who do not still exist. It is of critical necessity to improve outcomes in these patients and to work with them to stop abusing drugs of abuse.

Adherence to antiretroviral therapy and associated factors among Human immunodeficiency virus positive patients accessing treatment at Nekemte referral hospital, west Ethiopia, 2019

BACKGROUND

Antiretroviral therapy has a remarkable clinical effect in reducing the progress of Acquired Immune Deficiency Syndrome. The clinical outcome of Anti-Retroviral therapy depends on strict adherence. Poor adherence reduces the effectiveness of antiretroviral therapy and increases viral replication. With changes in service delivery over time and differences in socio-demographic status from region to region, it is essential to measure adherence. Therefore, this study aimed to assess adherence to antiretroviral therapy and its associated factors among HIV/AIDS patients accessing treatment at Nekemte referral hospital, West Ethiopia.

METHODS

Institutional based cross-sectional study was conducted on 311 HIV/AIDS patients from March 01 to March 30, 2019. The study participants were selected by a simple random sampling method and interviewed using structured questionnaires. Bivariable logistic regression was conducted to find an association between each independent variable and adherence to antiretroviral medication. Multivariable logistic regression was used to find the independent variables which best predict adherence. The statistical significance was measured using odds ratio at a 95% confidence interval with a p-value of less than 0.05.

RESULTS

Out of a total of 311 patients sampled, 305 were participated in the study, making a response rate of 98.07%. From these 305 study participants,73.1% (95% CI = 68.2, 78.0) were adherent to their medication. Having knowledge about HIV and its treatment (AOR = 8.24, 95% CI: 3.10, 21.92), having strong family/social support (AOR = 6.21, 95% CI: 1.39, 27.62), absence of adverse drug reaction (AOR = 5.33, 95% CI: 1.95, 14.57), absence of comorbidity of other chronic diseases (AOR = 5.72, 95% CI: 1.91, 17.16) and disclosing HIV status to the family (AOR = 5.08, 95% CI: 2.09, 12.34) were significantly associated with an increased likelihood of adherence to antiretroviral medication.

CONCLUSION

The level of adherence to antiretroviral therapy was found low compared to WHO recommendation. The clinician should emphasize reducing adverse drug reaction, detecting and treating co-morbidities early, improving knowledge through health education, and encouraging the patients to disclose their HIV status to their families.

Factors Influencing Effectiveness of Peer Education Against Nonadherence to Antiretroviral Therapy Among Adult People Living with HIV/AIDS: A Pre-Post Intervention Study in Arsi Zone, Ethiopia

Background

Nonadherence to antiretroviral therapy (ART) among people with HIV/AIDS can lead to drug resistance and death. Different studies have defined nonadherence, and it denotes at least one missed dose of ART within 28 days. One of the strategies to prevent nonadherence to ART could be peer education. However, published studies which test out whether or not peer education is effective for prevention of nonadherence to ART among adults living with HIV were not available. Moreover, published studies on factors discussing the success of peer education against nonadherence to ART were not available, so we conducted this study.

Objectives

To determine effectiveness of peer education against nonadherence to ART and identify factors influencing the effectiveness of peer education for prevention of nonadherence to ART among people living with HIV/AIDS in Arsi zone, Ethiopia.

Methods

An institution based pre-post intervention study was conducted. The intervention was giving peer education for three months. Frequencies and percentages were used to describe the data. Binary and multivariate logistic regressions were used to assess the variables.

Results

The data was collected from 355 and 319 people with HIV/AIDS at pre- and post-intervention stages, respectively. Experiencing an ART side effect, reminder to take ART, gender, marital status and monthly income were associated with nonadherence. More study participants who had not useda reminder to take ART service missed at least one dose of ART when compared to those who used a reminder to take ART service (adjusted odds ratio (AOR) =6.21; 95% CI=2.12–18.20).

Conclusion

Experiencing a side effect of ART influenced effectiveness of peer education negatively while using reminder to take ART influenced effectiveness positively. Peer education is effective for reduction of nonadherence to ART if it is used with reminder to take ART. This study can be a base for further studies that should be conducted in various areas, since peer education can be influenced by sociodemographic and economic factors.

Antiretroviral adherence and virologic suppression in partnered and unpartnered HIV-positive individuals in southern Brazil

Background

An undetectable serum HIV-1 load is key to effectiveness of antiretroviral (ARV) therapy, which depends on adherence to treatment. We evaluated factors possibly associated with ARV adherence and virologic response in HIV-infected heterosexual individuals.

Methods

A cross-sectional study was conducted in 200 HIV-1 serodiscordant couples and 100 unpartnered individuals receiving ARV treatment at a tertiary hospital in southern Brazil. All subjects provided written informed consent, answered demographic/behavioral questionnaires through audio computer-assisted self-interviews (ACASI), and collected blood and vaginal samples for biological markers and assessment of sexually transmitted infections (STIs). HIV-negative partners were counseled and tested for HIV-1.

Results

The study population mean age was 39.9 years, 53.6% were female, 62.5% were Caucasian, 52.6% had incomplete or complete elementary education, 63.1% resided in Porto Alegre. Demographic, behavioral and biological marker characteristics were similar between couples and single individuals. There was an association between adherence reported on ACASI and an undetectable serum viral load (P<0.0001). Logistic regression analysis demonstrated that single-tablet ARV-regimens were independently associated with adherence (OR = 2.3; 95CI%: 1.2–4.4; P = 0.011) after controlling for age, gender, education, marital status, personal income, ARV regimen, and median time of ARV use. A positive correlation between genital secretion PCR results and serum viral load was significant in the presence of STIs (r = 0.359; P = 0.017). Although HIV PCR detection in vaginal secretions was more frequent in women with detectable viremia (9/51, 17.6%), it was also present in 7 of 157 women with undetectable serum viral loads (4.5%), p = 0.005.

Conclusions

ARV single tablet regimens are associated with adherence. Detectable HIV-1 may be present in the genital secretions of women with undetectable viremia which means there is potential for HIV transmission in adherent individuals with serologic suppression.

Quality of life improvement, social stigma and antiretroviral treatment adherence: implications for long-term HIV/AIDS care

By 2020, the Vietnamese government has committed to having 90% of patients receiving ART as well as 90% of those on ART having successful viral suppression. Factors that influence adherence to ART among patients are essential to allowing the adequate care. This study was conducted across 8 outpatient clinics in Hanoi and Nam Dinh province and included 1133 patients living with HIV. Socioeconomic factors such as marital status, education, employment as well as health-related quality of life improvements were investigated as potentially being associated with adherence rates of ART patients. Through multivariate logistic regression analysis with self-reported ART adherence and VAS scores, this study was able to identify marital status and employment as two factors associated with positive adherence scores. Similarly, health problems, stigmatization, and duration on ART were associated negatively with ART adherence. Knowing that these factors may be linked to adherence rates, they can be preemptively managed with patients to enhance adherence rates and achieve successful viral suppression.
