Determinants of Late HIV Presentation at Ndlavela Health Center in Mozambique

HIV Symptom Clusters Among Sexual Minority Men in Ghana, West Africa: A Cross-sectional Study

ABSTRACT

The aims of this study were to determine if HIV symptoms among sexual minority men formed clusters and to examine the sociodemographic and clinical characteristics that are associated with these clusters. We analyzed cross-sectional data from Ghanaian sexual minority men ( N = 225) living with HIV. We used both principal component analysis and multivariable linear regression. Our findings indicate that sadness (64.0%) and headache (62.7%) were the most prevalent symptoms among our sample. Seven symptom clusters were identified: neurological symptoms, psychological symptoms, gastrointestinal symptoms, dermatological symptoms, self-concept/self-esteem, weight/diet-related symptoms, and sleep quality and potential disturbances. Late HIV diagnosis was significantly associated with higher distress scores for all symptom clusters except for the self-concept/self-esteem and gastrointestinal symptoms clusters. The findings emphasize the importance of early HIV symptom identification.

Are people with HIV at advanced disease stages being left behind? A global survey

INTRODUCTION

A substantial percentage of people with HIV are still admitted for care at advanced disease stages. Here, we investigate the availability of the supplies and infrastructure required to provide care for this population in healthcare facilities and explore correlations with local demand.

METHODS

AIDS Healthcare Foundation's partner facilities were invited to respond to a survey addressing the availability of services to support clients with advanced HIV. We present results per continent and according to gross national income per capita using frequencies and percentages. We generated country-level scores taking the average percentage of facilities with available resources on 10 key items and used Spearman's correlation to investigate relationships between country scores and local demand, depicted by the percentages of people with HIV newly enrolled in care with a CD4 T-cell count <200/mm3 in 2022.

RESULTS

A total of 643 facilities from 37 countries responded to the survey between September and December 2021. Overall, services requiring more costly equipment and/or supplies were less frequently available. Facilities in Africa, Asia, and Latin America/Caribbean and those with lower gross national income had a somewhat lower availability of diagnostic and therapeutic resources. Availability of services was not correlated with local demand: 14 countries (42%) had scores below the 50% percentile despite having >20% of newly enrolled people with HIV with a CD4 T-cell count <200/mm3.

CONCLUSION

Appropriate care can mitigate the morbidity and mortality associated with advanced HIV. We found that the healthcare services recommended by the World Health Organization as essential to support clients with advanced HIV are often unavailable in facilities providing HIV care, despite high local demand.

Defective proviruses significantly impact viral transcription and immune activation in men and women with HIV-1 subtype C in rural South Africa

Introduction

The main obstacle to achieving an HIV-1 cure is the proviral reservoir. To promote equity in HIV cure strategies, it is crucial to study the viral reservoir of the predominant HIV-1 subtype C in both women and men. Therefore, we investigated the dynamics of the (intact) viral reservoir in relation to plasma viral load (VL), CD4+ T cell count, and immune activation before and during 96 weeks of successful antiretroviral therapy (ART).

Methods

Eighty-two participants (62% female) newly initiating ART in a rural clinic in South Africa were included in the study. Blood samples were collected at baseline, week 48, and week 96, and CD4 count was determined. Plasma was used for VL and immune marker analyses, while isolated peripheral blood mononuclear cells (PBMCs) were used for the quantification of cellular multiple spliced HIV-1 RNA (msRNA) and the intact proviral DNA assay. For the longitudinal analyses on ART, we selected only those participants who durably suppressed their VL to <200 copies/mL during 48 (n=65) and/or 96 (n=60) weeks of treatment.

Results

At ART initiation, the median CD4 count was 234 cells/mm3 and VL was 68,897 copies/mL. Interestingly, at baseline the number of defective proviruses was significantly correlated with VL (p<0.0001), msRNA (p<0.0001), CD4 count (p=0.0008), CXCL10 (p=0.0003) and TNF-α (p=0.0394). During successful ART, a significant decrease of both the intact and defective proviral reservoir was observed (p<0.0001). The decrease of the intact proviral reservoir was more profound compared to the defective fraction after 96 weeks of therapy. In addition, a significant decrease in cellular msRNA and IL-6, IL-7, TNF-α, sCD14, sCD163, CCL2, CXCL10, and CRP was detected.

Discussion

This study underscores the significant relationship observed prior to therapy initiation between the number of defective proviruses, viral transcription/production and their association with immune response indicators such as CD4 count, CXCL10, and TNF-α. Furthermore, the observation of a less pronounced decrease of the defective proviral DNA highlights the importance of addressing both intact and defective proviruses in therapeutic strategies to enhance clinical outcomes for people with HIV-1. Together, these findings suggest a significant role of the defective proviruses in HIV-related disease progression.

Absolute CD4 count and percentage values among Libyan patients with HIV by single-platform flow cytometry

BACKGROUND

Single-platform flow cytometry technology together with CD45-gating is becoming the method of choice for absolute CD4 T cell enumeration. Immunological assessment of HIV patients by monitoring CD4 can provide valuable information on antiviral treatment response and disease progression.

METHODS

A total of 97 HIV-positive individuals were recruited from 2 hospitals in Tripoli, Libya, and 14 healthy blood donors. The HIV-infected individuals were classified by CD4+ count into HIV-positive (>200 cells/µL) or AIDS (≤200 cells/µL) groups. CD4+ and CD8+ cell counts were determined and compared among the groups and with similar published data.

RESULTS

The mean ± SD CD4+ cell counts were 1106 ± 442.8 cells/µL in healthy individuals, 460 ± 219.7 cells/µL in the HIV-positive group, and 78 ± 64.3 cells/µL in the AIDS group. The mean ± SD CD4+/CD8+ ratio was 1.6 ± 0.58, 0.4 ± 0.22, and 0.1 ± 0.1, respectively. CD4+ counts in Libyan healthy adults might be higher than those reported in several studies in other regions, whereas CD4+ counts in Libyan AIDS patients seem lower.

CONCLUSION

Reference values for T lymphocyte counts in Libyan healthy individuals should be investigated more extensively, and the reasons why Libyan AIDS patients seem to have such lower CD4+ counts should be examined.

Unveiling trends in late diagnosis among 22,504 people living with HIV in Hunan, China

This study examined the prevalence of HIV late diagnosis (LD) and identified associated factors with LD among people living with HIV (PLWH). We extracted sociodemographic, epidemiological, and immunological information between 2018 and 2021 in Hunan, China from the HIV/AIDS Comprehensive Response Information Management System of China. The chi-squared test and multivariable logistic regression model were used to identify the factors associated with LD. Among 22,504 PLWH, 14,988 (66.6%) were diagnosed late. PLWH aged 50 and older had a higher proportion of LD (71.2%) than the younger group (60.0%). Older age, being male, Han ethnicity, being registered in Western Hunan, being transferred from health facilities, and being infected through heterosexual intercourse were associated with LD. Among PLWH younger than 50 years, apart from the factors mentioned above, individuals who had primary school or lower education, were non-student, and were divorced or widowed were more likely to be diagnosed late. Unlike younger PLWH, these factors were not associated with LD in the older group. But regional disparities in LD were more significant among them. LD in PLWH remains a severe issue, especially among older people. The study findings provided valuable insights into designing programs targeting groups at higher risk of LD to reduce its prevalence.

Sociobehavioral Risk Factors and Clinical Implications of Late Presentation Among People Living with HIV in the Brazilian Amazon Region

This study aimed to analyze the prevalence, sociobehavioral factors and clinical-laboratory consequences of late presentation among people living with HIV (PLHIV) in the Brazilian Amazon region. In total, 402 HIV + individuals treated at reference units in Belém city (Pará, Brazil) between 2018 and 2019 were evaluated. Late presentation was defined as a first-collection LTCD4+ count below 350 cells/µL. Sociodemographic, behavioral and clinical data were obtained from questionnaires or medical records. Th1, Th2 and Th17 cytokine profiles were evaluated by flow cytometry. Longitudinal data on viral load, T lymphocytes, and antiretroviral therapy administration were obtained from control and logistic databases. Approximately 52.73% of the participants were late presenters and sought medical care 7-12 + months after their primary HIV diagnosis. Sociobehavioral factors associated with late presentation included illicit drug use for more than 5 years, polyamory, no alcohol consumption, homosexuality, and sexual inactiveness after HIV diagnosis. Clinically, late presentation was associated with coinfection rate; polysymptomatology; high IFN-ɣ, IL-6 and IL-10 levels; nonresponse to antiretroviral therapy; and virological failure- and tuberculosis coinfection-motivated changes to therapy. In summary, the prevalence of late presentation in Pará in the Brazilian Amazon region is high. Delays in seeking specialized care after a primary HIV diagnosis cause medium/long-term changes in the life expectancy and health of PLHIV.

High prevalence of late presentation with advanced HIV disease and its predictors among newly diagnosed patients in Kumasi, Ghana

BACKGROUND

Late presentation with advanced HIV disease (LP-AHD) remains a significant challenge to Human Immunodeficiency Virus (HIV) care, contributing to increased morbidity, mortality, and healthcare costs. Despite global efforts to enhance early diagnosis, a considerable proportion of individuals with HIV infection are unaware of being infected and therefore present late for HIV care. For the first time in Ghana, this study assessed the prevalence of LP-AHD and associated factors among people diagnosed with HIV (PDWH).

METHOD

This bi-center retrospective cross-sectional study included 315 PDWH at the Aniniwah Medical Centre and Komfo Anokye Teaching Hospital, both in Kumasi, Ghana. A well-structured questionnaire was used to collect data on sociodemographic, clinical, lifestyle and psychosocial factors from the study participants. Statistical analyses were done in SPSS version 26.0 and GraphPad Prism version 8.0 at significant p-value of < 0.05 and 95% confidence interval. Predictors of LP-AHD were assessed using binary logistic regression models.

RESULTS

This study observed that, 90 out of the 315 study PDWH (28.6%) reported late with advanced HIV disease (AHD). Participants within the age group of 36-45 years (adjusted Odds Ratio [aOR]: 0.32, 95% CI: 0.14-0.69; p = 0.004) showed a significantly decreased likelihood of LP-AHD. However, participants who perceived cost of HIV care to be high (aOR: 7.04, 95% CI: 1.31-37.91; p = 0.023), who were diagnosed based on clinical suspicion (aOR: 13.86, 95 CI: 1.83-104.80; p = 0.011), and missed opportunities for early diagnosis by clinicians (aOR: 2.47, 95% CI: 1.30-4.74; p = 0.006) were significantly associated with increased likelihood of LP-AHD.

CONCLUSION

The prevalence of LP-AHD among PDWH in Ghana is high. Efforts to improve early initiation of HIV/AIDS care should focus on factors such as the high perceived costs of HIV care, diagnosis based on clinical suspicion, and missed opportunities for early diagnosis by physicians.

Yasin M, Mat Nasir N, Mohamad M. The association between HIV-related stigma, HIV knowledge and HIV late presenters among people living with HIV (PLHIV) attending public primary care clinic settings in Selangor

INTRODUCTION

HIV late presenters were defined as individuals presenting with a CD4 count below 350 cells/μL or with an AIDS-defining event, according to the European Late Presenter Consensus working group. Early diagnosis and treatment of HIV have proven beneficial for people living with HIV (PLHIV), reducing the burden on healthcare systems, and contributing to ending the HIV/AIDS epidemic. However, in Malaysia, over 50% of newly diagnosed HIV patients present late, leading to increased morbidity and premature mortality. This study aims to determine the prevalence of late HIV presenters and its association with HIV-related stigma and HIV knowledge among PLHIV attending public primary care clinics in Selangor.

METHODS

A cross-sectional study was conducted at selected public health clinics in Selangor, involving PLHIV aged 18 years and older, who were diagnosed since 2019. HIV-related stigma was measured using the Malay version of Berger's HIV Stigma Scale, and HIV knowledge was assessed using the Malay version of Brief HIV-KQ-18. Univariate and multivariate logistic regression analyses were performed to identify factors associated with late HIV presentation.

RESULTS

A total of 400 participants were included in the study, with 60.0% (n = 240, 95% CI: 55.0-65.0) classified as late presenters. The participants had a mean age of 30.29 (±7.77) years. The risk factors for late presenters were high levels of HIV-related stigma (aOR = 1.049, 95% CI: 1.034-1.063, p-value <0.001), low levels of HIV knowledge (aOR = 0.709, 95% CI: 0.646-0.778, p-value <0.001), tertiary education background (aOR = 15.962, 95% CI: 1.898-134.235, p-value = 0.011), and being single (aOR = 3.582, 95% CI: 1.393-9.208, p-value = 0.008).

CONCLUSION

This study highlights the association between high levels of HIV-related stigma, low levels of HIV knowledge, and late HIV presentation. Interventions targeting stigma reduction and HIV education can promote early testing and prompt access to care, improving health outcomes for PLHIV.

Has COVID-19 Changed the Incidence and Profile of Late Presenters for HIV Infection in Lodz, Polish Reference Centre, Poland?

Objectives: The aim of this study was to compare the prevalence and characteristics of HIV late presenters (LPs) and advanced LPs (aLPs) registered in the Lodz HIV centre during the COVID-19 pandemic (2020-2021) with those of the pre-pandemic period (2017-2019). Methods: A retrospective analysis was performed of the predictive factors associated with HIV LPs and aLPs based on multivariable logistic regression. The patient entry into specialist HIV care after diagnosis during the pandemic was analysed. Results: Of 121 newly diagnosed HIV infections during the pandemic, 49.6% had late presentation and 36.4% had advanced HIV disease (AHD). In the pre-pandemic period, out of 154 newly diagnosed patients, 58.4% were LPs and 38.3% were aLPs. Independent risk factors for HIV late presentation were older age (OR: 1.04, 95% CI: 1.01-1.076; p = 0.008), diagnosis in hospital (OR: 5.63, 95% CI: 2.87-11.05; p < 0.001) and negative VDRL as compared to positive VDRL (OR: 2.48, 95% CI: 1.19-5.15; p = 0.015). The same predictive factors were associated with aLPs: older age (OR: 1.07, 95% Cl 1.04-1.11; p < 0.001), HIV diagnosis in hospital (OR: 4.25, 95% CI 2.17-8.29; p < 0.001) and negative VDRL as compared to positive VDRL (OR: 4.95, 95% CI 1.87-13.10; p = 0.001). HIV diagnosis during the pandemic was not a risk factor for late presentation nor for advanced late presentation. However, the time between HIV diagnosis and the first visit to an HIV centre was statistically lower in the pre-pandemic period (p = 0.0048); the median lengths of time between the date of HIV testing, the first visit to the centre and the initiation of ART did not differ between these two periods in LPs and aLPs (p > 0.05). Conclusions: The COVID-19 pandemic did not change the prevalence or characteristics of late presentation and aLPs among newly diagnosed patients, nor did it extend the time to enrolment in HIV care or ART introduction in these groups.

Psychometric properties of stigma and discrimination measurement tools for persons living with HIV: a systematic review using the COSMIN methodology

BACKGROUND

The development of antiretroviral therapy broadly extends the life expectancy of persons living with HIV (PLHIV). However, stigma and discrimination are still great threat to these individuals and the world's public health care system. Accurate and reproducible measures are prerequisites for robust results. Therefore, it is essential to choose an acceptable measure with satisfactory psychometric properties to assess stigma and discrimination. There has been no systematic review of different stigma and discrimination tools in the field of HIV care. Researchers and clinical practitioners do not have a solid reference for selecting stigma and discrimination measurement tools.

METHODS

We systematically searched English and Chinese databases, including PubMed, EMBASE, CINAHL, Web of Science, PsycINFO, ProQuest Dissertations and Theses, The Cochrane Library, CNKI,, and Wanfang, to obtain literature about stigma and discrimination measurement tools that have been developed and applied in the field of HIV. The search period was from 1st January, 1996 to 22nd November 2021. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline (2018 version) was applied to assess the risk of bias for each involved study and summarize the psychometric properties of each tool. The modified version of the Grading of Recommendations Assessment, Development, and, Evaluation (GRADE) method was used to grade the evidence and develop recommendations.

RESULTS

We included 45 studies and 19 PROMs for HIV/AIDS-related stigma and discrimination among PLHIV. All studies had sufficient methodological quality in content validity, structural validity, internal consistency, and the hypothesis testing of structural validity. Limited evidence was found for cross-cultural validity, stability, and criterion validity. No relevant evidence was found concerning measurement error and responsiveness. The Internalized AIDS-related Stigma Scale (IARSS), Internalized HIV Stigma Scale (IHSS), and Wright's HIV stigma scale (WHSS) are recommended for use.

CONCLUSIONS

This study recommends three PROMs for different stigma and discrimination scenarios, including IARSS for its good quality and convenience, IHSS for its broader range of items, higher sensitivity, and greater precision, and WHSS for its comprehensive and quick screening. Researchers should also consider the relevance and feasibility of the measurements before putting them into practice.

Risk Factors for Late HIV Presentation in Patients Treated at a Single Belgian Reference Centre from 2018 to 2022

A late HIV diagnosis is associated with increased mortality and morbidity, increased healthcare costs and increased onward viral transmission. In this regard, we retrospectively analysed the characteristics of patients who presented for care at our centre from January 2018 to December 2022 to assess the proportion of patients and factors associated with late HIV presentation. We collected data from the Liège University Hospital database, and we used binary logistic regression models to analyse the impact of individuals' characteristics on late presentation. Among 167 participants, 38.3% were late presenters (LPs) (presenting for care with a CD4+ T-cell count < 350 cells/mm3 or after an AIDS-defining event), and 21.6% were late presenters with advanced disease (LPs-AD) (presenting for care with a CD4+ T-cell count < 200 cells/mm3 or after an AIDS-defining event). The risk of being an LPs-AD was increased in older individuals (OR on log-transformed age: 7.5) and individuals of sub-Saharan African origin compared to individuals of Belgian or other origin (ORs of 0.30 and 0.25, respectively). The results of this study suggest that broadening the focus beyond the previously common risk groups is essential to prevent late diagnosis.

Understanding gender differences of people with HIV newly diagnosed or returning to care with advanced HIV disease in Malawi: a qualitative study

BACKGROUND

Despite tremendous progress in improving antiretroviral therapy (ART) access, advanced HIV disease (AHD) still remains a challenge globally. Reasons for delayed presentation to care and ART adherence may be affected by gender. We present qualitative study findings on gender differences in decisions for HIV testing and ART initiation/adherence in adults with AHD in Malawi.

METHODS

We used a qualitative study design, interviewing 16 men and 16 women aged 18 years and above diagnosed with AHD in sites implementing an optimized package of AHD care, from December 2021-February 2022. We included study participants receiving AHD services for at least two months. We also interviewed 16 lay workers and 16 health care workers supporting people living with AHD. In-depths interviews (IDIs) were conducted in English or Chichewa by trained research assistants using semi-structured interview guides. A short-answer analysis was conducted, and findings were interpreted according to thematic areas.

RESULTS

Both men and women reported stigma as a main barrier influencing their decision to test for HIV and to initiate and adhere to ART. Fear of side effects, insufficient food, and the need for more information were other barriers reported among men and women as well as perceived as barriers by HCWs. Men appear to have tested later for HIV and stated that they were waiting until experiencing significant symptoms before testing. According to clients and HCWs, men were also less inclined to initiate ART after a HIV diagnosis, whereas women were motivated to start treatment to remain healthy and care for the family. Both genders reported that treatment could be delayed if they were feeling healthy. Treatment fatigue was reported among all groups as the main reason to discontinue treatment.

CONCLUSIONS

There were similarities and differences between genders in decision-making about HIV care. Concerns about stigma were important reasons for delay in HIV care in both genders. Motivations for accessing HIV treatment and care were different among men and women, pushing the need for gender-tailored counseling services and community messaging that educate both men and women on the benefits of initiating ART early, in turn reducing the number of people presenting with AHD.

Factors Associated with Late Diagnosis of Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) in a University Hospital in Brazil: Challenges to Achieving the 2030 Target

INTRODUCTION

This study aimed to identify factors associated with late diagnosis and clinically monitor newly diagnosed HIV/AIDS patients.

METHOD

Retrospective study, based on secondary data from a specialized unit at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto of the University of Sao Paulo. Data collection included sociodemographic, behavioral, clinical, and laboratory data of newly diagnosed HIV patients between 2015 and 2019. Data analysis was undertaken using inferential statistical tests.

RESULTS

A total of 314 individuals were newly diagnosed with HIV/AIDS, 86.6% (272) had a late diagnosis and 53.8% (169) were diagnosed very late. Using the adjusted odds ratio, we observed that bisexual and MSM patients were less likely to have a late diagnosis compared to straight patients. Individuals who entered through the emergency department and Outpatient Clinic had a lower chance of having a very late diagnosis compared to those diagnosed in the ward/inpatient unit. Having a higher education and university education were protective factors against having a very late diagnosis of HIV infection compared to elementary school education only. In addition, male patients were more likely to have a very late diagnosis compared to female patients.

CONCLUSIONS

This study evidenced a high prevalence of late and very late diagnoses. Therefore, attention should be directed towards factors related to late and very late presentation.

Understanding the quality of life of people living with HIV in rural and urban areas in Indonesia

Human Immunodeficiency Virus (HIV) is a major global public health issue that affects the quality of life (QoL) of people living with HIV (PLHIV) globally and in Indonesia. As a part of a large-scale qualitative study investigating HIV risk factors and impacts on PLHIV and facilitators of and barriers to their access to HIV care services in Yogyakarta and Belu, Indonesia, this paper describes their in-depth views and experiences of the influence of HIV on their QoL. Ninety-two participants were recruited using the snowball sampling technique. Data were collected using in-depth interviews. In addition, the World Health Organisation Quality of Life questionnaire (WHOQOL-HIV BREF) was also distributed to each of them to fill out prior to the interviews. Chi-Square analysis was used to analyse data from the survey and a framework analysis was applied to guide qualitative data analysis. The findings reported several factors affecting the QoL of the participants. These included (i) environmental factors, such as living in rural areas, the unavailability of HIV care services and public transport, and long-distance travel to healthcare facilities; (ii) personal beliefs associated with HIV; (iii) sexual and social relationships and their influence of the QoL of participants; and (iv) level of independence and physical health condition following HIV diagnosis. The findings indicate the need for intervention programs that address the availability and accessibility of HIV care services to PLHIV within rural communities and support various physical, psychological, and financial needs of PLHIV. These can be implemented by providing supplements and nutritious food, HIV counselling and door-to-door/community-based ART service delivery to PLHIV, which may increase their engagement in and adherence to the treatment and improve their physical and psychological condition and QoL.

Evaluation of the late presentation and associated factors of people living with HIV in Turkey

To identify the frequency of late presentation and late presentation with advanced disease, and associated factors in people living with HIV (PLHIV). Data from PLHIV diagnosed between 2008 and 2021 were retrospectively analyzed. Time of diagnosis (categorized based on key events affecting HIV care continuum e.g., national strategies, HIV guidelines, COVID-19 pandemic) and characteristics of late presenters (LP: CD4 ≤350 cells/mm³ or an AIDS defining event) and late presenters with advanced disease (LPAD: CD4 <200 cells/mm³) were describe. Associations between dependent (LP, LPAD) and independent variables were assessed using univariate/multivariate regression tests and presented as odds ratios (95% confidential interval). Of 1585 individuals (93.7% men), 42.5% were LPs and 19.3% were LPADs. Most common route of transmission was sex between men (54.3%). Non-LPs were younger (30 vs. 34 and 36 years; p < 0.001) and included more men who have sex with men (60.3% vs. 46.3% and 39.5%; p < 0.001). Factors associated with being LP and LPAD were age >30 years, heterosexual/unknown route of transmission (vs. sex between men), diagnosis in 2008-2013 or 2020-2021, (vs. 2014-2019). With reference to Turkish subjects, migrants from Africa had higher odds of being LPAD. LP is still an important health issue in HIV care. Heterosexuality, older age (>30 years), migration from Africa, and the COVID-19 pandemic are associated with delays in HIV presentation in Turkey. These factors need to be considered when developing and implementing policies to enable earlier diagnosis and treatment of PLHIV to achieve UNAIDS 95-95-95 targets.
