Reckoning with mortality: global health, HIV, and the politics of data

The impact of shifts in PEPFAR funding policy on HIV services in Eastern Uganda (2015-21)

Although donor transitions from HIV programmes are increasingly common in low-and middle-income countries, there are limited analyses of long-term impacts on HIV services. We examined the impact of changes in President's Emergency Plan for AIDS Relief (PEPFAR) funding policy on HIV services in Eastern Uganda between 2015 and 2021.We conducted a qualitative case study of two districts in Eastern Uganda (Luuka and Bulambuli), which were affected by shifts in PEPFAR funding policy. In-depth interviews were conducted with PEPFAR officials at national and sub-national levels (n = 46) as well as with district health officers (n = 8). Data were collected between May and November 2017 (Round 1) and February and June 2022 (Round 2). We identified four significant donor policy transition milestones: (1) between 2015 and 2017, site-level support was withdrawn from 241 facilities following the categorization of case study districts as having a 'low HIV burden'. Following the implementation of this policy, participants perceived a decline in the quality of HIV services and more frequent commodity stock-outs. (2) From 2018 to 2020, HIV clinic managers in transitioned districts reported drastic drops in investments in HIV programming, resulting in increased patient attrition, declining viral load suppression rates and increased reports of patient deaths. (3) District officials reported a resumption of site-level PEPFAR support in October 2020 with stringent targets to reverse declines in HIV indicators. However, PEPFAR declared less HIV-specific funding. (4) In December 2021, district health officers reported shifts by PEPFAR of routing aid away from international to local implementing partner organizations. We found that, unlike districts that retained PEPFAR support, the transitioned districts (Luuka and Bulambuli) fell behind the rest of the country in implementing changes to the national HIV treatment guidelines adopted between 2017 and 2020. Our study highlights the heavy dependence on PEPFAR and the need for increasing domestic financial responsibility for the national HIV response.

'Ending AIDS' between comparison and commensuration and the role of global health indicators

The use of targets and indicators in global health has become ubiquitous within global health and disease elimination programmes. The drive to 'end AIDS' has become a global flagship endeavour, including nation-states, donor organisations, NGOs, pharmaceutical companies, medical researchers, and activists. Almost synonymous with the campaign of ending AIDS is UNAIDS' 90-90-90 targets. Beyond indicators' role in neoliberal global health, an essential aspect of indicators and quantitative metrics is their ability to provide a basis for measurements and comparability across time and between different actors and entities. These processes are based on what has been called, commensuration, visual simplification, and serialisation. This article seeks to provide an account of how we can think about indicators in the drive to end AIDS as doing work that is contingent upon commensuration, simplification, and serialisation. The argument is that by attending to issues of commensuration, visual simplification, and serialisation we are better able to see how we risk erasing and foreclosing other forms of conceptualising what the end of AIDS could be. Logics of quantification risks erasing and foreclosing other qualitative aspects of the HIV epidemic as well as obscuring various epistemological tensions inherent in counting towards the end of AIDS.

Bacterial Infections in Patients Living with HIV

Pneumonia, as well as other types of acute and chronic lung injuries, remain the leading causes of death in individuals living with HIV. Individuals with HIV who are on antiretroviral therapy continue to have a greater risk for pneumonia, including bacterial and mycobacterial infections. Alveolar macrophages and lung epithelial cells constitute the first line of host defense against invading pathogens. The predisposition of individuals living with HIV to infections despite ante-retroviral therapy is mechanistically related to HIV pro-viruses integrating into host cells, including airway epithelial cells and alveolar macrophages. Alveolar macrophages harbor latent HIV even when individuals appear to have complete suppression on ART. In parallel, pneumonia can irreversibly impair lung function in HIV-infected individuals. Cells that Macrophages exposed to HIV or HIV-related proteins have been shown to secrete exosomes that contain miRNAs. These exosomes can regulate several innate and acquired immune functions by stimulating cytokine production and inflammatory responses. Furthermore, these secreted exosomal miRNAs can shuttle between cells, causing cellular dysfunction in the case of epithelial cells; they disrupt lung epithelial barrier dysfunction, which leads to a predisposition to bacterial infections. We discuss the common bacterial infections that occur in patients living with HIV and provide mechanistic insights into how the intercellular communication of miRNAs results in cellular dysfunction.

A model for predicting high BMI of people living with HIV after receiving antiretroviral therapy

Objective:

The objective of this study was to evaluate the characteristics of high body mass index (BMI) and normal weight people living with HIV after antiretroviral therapy (ART) and establish a model.

Methods:

A total of 290 people living with HIV after 1 year of ART treatment were enrolled and divided into two groups based on whether their BMI index was <24 or ⩾24 at week 48. The demographic, clinical data were collected and analyzed. Multivariable logistic regression analysis was performed. A model was established and use to predict the occurrence of certain diseases.

Results:

A total of 290 people living with HIV were included in this study; 200 had a normal BMI (BMI < 24) and 90 were high BMI (BMI ⩾ 24) after 1-year ART. Their baseline characteristics were significantly different in relation to age (p = 0.007), sex distribution (p = 0.040), ART regimen (p = 0.040), alanine aminotransferase levels (p < 0.001), and three major serum lipid levels: triglycerides (p < 0.001), cholesterol (p = 0.011), and low-density lipoprotein (p = 0.005). A multivariate logistic regression analysis resulted in the development of a model for the diagnosis of high BMI and hyperlipidemia. The model score is an independent risk factor for hyperlipidemia (odds ratio = 2.674, p = 0.001) and high BMI (p < 0.001). The model score is significantly correlated with the controlled attenuation parameter (CAP) value (r = 0.230, p < 0.001) and can be used to divide the severity of liver steatosis based on CAP value.

Conclusions:

This study demonstrated a easy-to-use model to detect high BMI, hyperlipidemia, and liver steatosis in people living with HIV without risk factors for BMI changing at baseline after 1 year of ART treatment.

Prevention and control of HIV/AIDS in China: lessons from the past three decades

ABSTRACT

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.

Knowledge of occupational exposure to HIV among healthcare workers in college campus clinics and tertiary hospitals

As the number of college students infected with the human immunodeficiency virus (HIV) has increased significantly in China, the risk of occupational exposure to HIV among healthcare workers (HCW) in college campus clinics has also increased. Our study aimed to evaluate the awareness of HCWs in terms of preventing occupational HIV exposure in college campus clinics compared with HCWs in tertiary hospitals. This cross-sectional study was conducted in nine provinces in China from September to October 2019 (10 college campus clinics, 7 tertiary hospitals). The study's response rate was recorded to be at 87.62% (184 of 210). The knowledge score of HIV among all HCWs was determined to be generally low (67.17 ± 11.17 points), and that of college campus clinics and tertiary hospitals showed no significant difference (66.36 ± 10.36 vs. 67.63 ± 11.61 points, P=0.463). Overall, HCWs in both college campus clinics and tertiary hospitals showed inadequate knowledge regarding occupational HIV exposure. Training for the prevention of occupational HIV exposure should be strengthened in both medical institutions.

Stem cell-like memory T cells: A perspective from the dark side

Much attention has been paid to a newly discovered subset of memory T (T_M) cells-stem cell-like memory T (T_SCM) cells for their high self-renewal ability, multi-differentiation potential and long-term effector function in adoptive therapy against tumors. Despite their application in cancer therapy, an excess of T_SCM cells also contributes to the persistence of autoimmune diseases for their immune memory and HIV infection as a long-lived HIV reservoir. Signaling pathways Wnt, AMPK/mTOR and NF-κB are key determinants for T_M cell generation, maintenance and proinflammatory effect. In this review, we focus on the phenotypic and functional characteristics of T_SCM cells and discuss their role in autoimmune diseases and HIV-1 chronic infection. Also, we explore the potential mechanism and signaling pathways involved in immune memory and look into the future therapy strategies of targeting long-lived T_M cells to suppress pathogenic immune memory.
