Barriers and Facilitators to HIV Care Linkage and Retention Among Older Adults Diagnosed With HIV in Malaysia: A Qualitative Study

INTRODUCTION

Older adults newly diagnosed with HIV experience poorer prognosis and higher mortality compared with those diagnosed at younger ages. We explored the barriers and facilitators in HIV care linkage and retention among newly diagnosed older persons living with HIV (OPLWH) in Malaysia.

METHODS

We conducted in-depth interviews with OPLWH and focus group discussions with health care providers (HCPs) from 5 specialties (primary care medicine, psychological medicine, gynecology, geriatrics, and infectious disease) at a tertiary hospital between September 2021 and April 2022. All sessions were audio-recorded, transcribed verbatim, and analyzed thematically.

RESULTS

We recruited 16 OPLWH and 7 HCPs. Thirteen OPLWH were male. Eight of them self-identified as men who have sex with men, and the rest were heterosexual. Diagnosis of HIV was between the ages of 50 and 61 years. Barriers and facilitators could be categorized into 3 levels: individual, interpersonal, and institutional. Individual barriers included misinformation about HIV treatment, unable to afford HIV-related services, and belief that life was futile. Interpersonal barriers were HIV-related stigma, poor social and family support, and social prejudice toward men who have sex with men. Lastly, institutional barriers were the need for frequent hospital visits, high cost for HIV-related services, a lack of guidance after diagnosis, and poor communication with HCPs. Facilitators included doctor or friend support and positive institutional reputation.

CONCLUSIONS

Multiple challenges hindered optimal care for OPLWH after HIV diagnosis. Issues like high costs, belief that treatment is futile, and a lack of family support need to be addressed as part of long-term support services for OPLWH.

Retention in Care and Virological Failure among Adult HIV-Positive Patients on First-Line Antiretroviral Treatment in Maputo, Mozambique

INTRODUCTION

Access to antiretroviral treatment (ART) is increasingly available worldwide; however, the number of patients lost to follow-up and number of treatment failures continue to challenge most African countries.

OBJECTIVES

To analyse the retention in clinical care and the virological response and their associated factors of HIV-1 patients from the Maputo Military Hospital (MMH).

METHODS

A cross-sectional observational study was conducted to analyse data from patients who started ART between 2016 and 2018 in the MMH.

RESULTS

At the end of 12 months, 75.1% of 1247 patients were active on clinical follow-up and 16.8% had suspected virologic failure (VL > 1000 copies/mm3). Patients younger than 40 years old were more likely to be lost to follow-up when compared to those aged >50 years old, as well as patients who were unemployed and patients with a CD4 count < 350 cells/mm3. Patients with haemoglobin levels lower than 10 g/dL and with a CD4 count < 350 cells/mm3 were more likely to have virological failure.

CONCLUSIONS

We have identified clinical and sociodemographic determinants of loss to follow-up and in the development of virological failure for HIV-positive patients in clinical care in the MMH. Therefore, HIV programs must consider these factors to increase the screening of patients at high risk of poor outcomes and particularly to strengthen adherence counselling programs.

Impact of IL-12B Genetic Variants on Antiviral Treatment Response among Hepatitis B Patients in Pakistan

HBV is a continuous major global health concern. Genetic factors of hosts are known to play a role in HBV infection outcomes. This study aimed to reveal the association of IL-12b 3′ UTR variant rs3212227 in HBV patients. Genotyping was performed using ARMS-PCR to detect IL-12b rs3212227 polymorphism. The patients were categorized into groups based on their response to the antiviral therapy. Group I: non-sustained virological response (NSR); Group II: sustained virological responders (SVR); and Group III: HBV-positive fresh cases. ALT levels were measured to evaluate liver function, and viral load was determined to evaluate viral infectivity among the study groups. The variant genotype CC was found to be significantly associated with the non-sustained virological response to the antiviral therapy (with a p-value of 0.0117; OR = 2.914; RR = 1.556). It was also determined that the genotype CC was the most prevalent genotype among both genders in the NSR group. Viral load was found to be 6-fold higher in Group III compared to Group I and Group II. The results suggest that genotype CC is the most prevalent genotype in the NSR groups, and it is associated with a poor response to antiviral therapy in Pakistani patients with HBV infection.

Effects of undernutrition on mortality and morbidity among adults living with HIV in sub-Saharan Africa: a systematic review and meta-analysis

Background

Undernutrition is one of the most common problems among people living with HIV, contributing to premature death and the development of comorbidities within this population. In Sub-Saharan Africa (SSA), the impacts of these often inter-related conditions appear in a series of fragmented and inconclusive studies. Thus, this review examines the pooled effects of undernutrition on mortality and morbidities among adults living with HIV in SSA.

Methods

A systematic literature search was conducted from PubMed, EMBASE, CINAHL, and Scopus databases. All observational studies reporting the effects of undernutrition on mortality and morbidity among adults living with HIV in SSA were included. Heterogeneity between the included studies was assessed using the Cochrane Q-test and I² statistics. Publication bias was assessed using Egger’s and Begg’s tests at a 5% significance level. Finally, a random-effects meta-analysis model was employed to estimate the overall adjusted hazard ratio.

Results

Of 4309 identified studies, 53 articles met the inclusion criteria and were included in this review. Of these, 40 studies were available for the meta-analysis. A meta-analysis of 23 cohort studies indicated that undernutrition significantly (AHR: 2.1, 95% CI: 1.8, 2.4) increased the risk of mortality among adults living with HIV, while severely undernourished adults living with HIV were at higher risk of death (AHR: 2.3, 95% CI: 1.9, 2.8) as compared to mildly undernourished adults living with HIV. Furthermore, the pooled estimates of ten cohort studies revealed that undernutrition significantly increased the risk of developing tuberculosis (AHR: 2.1, 95% CI: 1.6, 2.7) among adults living with HIV.

Conclusion

This review found that undernutrition has significant effects on mortality and morbidity among adults living with HIV. As the degree of undernutrition became more severe, mortality rate also increased. Therefore, findings from this review may be used to update the nutritional guidelines used for the management of PLHIV by different stakeholders, especially in limited-resource settings.

Immunological and Virological Responses in Older HIV-Infected Adults Receiving Antiretroviral Therapy: An Evidence-Based Meta-Analysis

BACKGROUND

Millions of people living with the HIV have received antiretroviral therapy (ART). Older adults make up a significant portion of these individuals; however, the immunological and virological responses to ART for older patients still need to be clarified.

DESIGN

Meta-analysis.

METHODS

In this article, we systematically reviewed research articles published between 2001 and 2018 that reported immunological and virological responses and AIDS-related mortality among HIV- infected adults (including individuals aged 50 years and older) receiving ART, using meta-analysis. ART efficiency was measured using 3 outcomes: (1) immunological response, (2) virological response, and (3) mortality.

RESULTS

We identified 4937 citations, and 40 studies were eventually selected to investigate ART efficiency in older HIV-infected patients, comprising more than 888,151 patients initiating ART. We report that older patients showed poor immunological responses, with CD4 counts and the restoration of CD4 counts after ART initiation being significantly lower than seen in younger patients. However, older patients exhibited better viral suppression rates (risk ratio: 1.04; 95% confidence intervals: 1.01 to 1.08) after 36 months following ART initiation. In addition, older adults had a higher risk of AIDS-related death (adjusted hazard ratio: 1.44, 95% confidence interval: 1.30 to 1.60).

CONCLUSIONS

Older age after ART initiation was associated with a poorer immunological response and a higher risk of mortality, suggesting the need to increase early diagnosis and treatment among older HIV patients.

Immunologic and virologic responses to antiretroviral therapy in treatment-naïve, HIV-infected elderly patients

Currently available data on immunologic and virologic responses to antiretroviral therapy (ART) in elderly patients are conflicting. The primary objective of this study was to assess immunologic and virologic responses to ART in treatment-naïve, HIV-infected elderly patients compared to younger patients. This was a single center, retrospective, descriptive study including treatment-naïve, HIV-infected adults initiated on ART between 1 January 2005 and 30 April 2015. Immunologic and virologic responses were compared between the ages ≥50 and < 50 years old. A total of 158 patients were included. By 14 months of ART, 85.9% (n = 67/78) of the patients ≥50 years old and 92.5% (n = 74/80) of those < 50 years old achieved immunologic response (p = 0.02). By 24 weeks of ART, 64.1% (n = 50/78) of the patients ≥50 years old and 65% (n = 52/80) of those < 50 years old achieved virologic response (p = 1). The amount of time it took the elderly patients to achieve virologic suppression was not significantly different compared to the younger patients (p = 0.459). Treatment-naïve, HIV-infected elderly patients achieved virologic response to ART that was comparable to younger patients although their immunologic response to ART was significantly lower.
