Thavarajah JJ, Hønge BL, Wejse CM. The Use of Broadly Neutralizing Antibodies (bNAbs) in HIV-1 Treatment and Prevention. Viruses 2024; 16:911. [PMID: 38932203 PMCID: PMC11209272 DOI: 10.3390/v16060911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 05/24/2024] [Accepted: 05/31/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Although antiretroviral therapy (ART) effectively halts disease progression in HIV infection, the complete eradication of the virus remains elusive. Additionally, challenges such as long-term ART toxicity, drug resistance, and the demanding regimen of daily and lifelong adherence required by ART highlight the imperative need for alternative therapeutic and preventative approaches. In recent years, broadly neutralizing antibodies (bNAbs) have emerged as promising candidates, offering potential for therapeutic, preventative, and possibly curative interventions against HIV infection. OBJECTIVE This review aims to provide a comprehensive overview of the current state of knowledge regarding the passive immunization of bNAbs in HIV-1-infected individuals. MAIN FINDINGS Recent findings from clinical trials have highlighted the potential of bNAbs in the treatment, prevention, and quest for an HIV-1 cure. While monotherapy with a single bNAb is insufficient in maintaining viral suppression and preventing viral escape, ultimately leading to viral rebound, combination therapy with potent, non-overlapping epitope-targeting bNAbs have demonstrated prolonged viral suppression and delayed time to rebound by effectively restricting the emergence of escape mutations, albeit largely in individuals with bNAb-sensitive strains. Additionally, passive immunization with bNAb has provided a "proof of concept" for antibody-mediated prevention against HIV-1 acquisition, although complete prevention has not been obtained. Therefore, further research on the use of bNAbs in HIV-1 treatment and prevention remains imperative.

Abstract
In April 1984, 40 years ago, the Secretary of the US Department of Health and Human Services announced that Dr. Robert Gallo and his colleagues at the National Cancer Institute (NCI) had confirmed the cause of acquired immunodeficiency syndrome (AIDS) as a retrovirus, which became known as human immunodeficiency virus (HIV) in 1986. For the past 40 years, prevention and cure of HIV infection have been the dual 'holy grail' sought but still not achieved. By the beginning of 2024, the World Health Organization (WHO) estimated that in the past 40 years, between 65.0 million and 113.0 million people have been infected with HIV, and between 32.9 million and 51.3 million people have died from HIV infection. On 29 February 2024, the WHO published an updated report in response to increasing reports of HIV drug resistance (HIVDR). Currently, HIV vaccines in development are in early-stage clinical trials. People with HIV are more likely to develop tuberculosis, with increasing rates of antimicrobial resistance. MTBVAC is the first live attenuated vaccine to prevent Mycobacterium tuberculosis infection, with phase 2a safety and efficacy clinical trial data expected at the end of 2024. This editorial aims to summarize the current challenges and hopes for developing vaccines to prevent HIV infection and approaches to overcome antiretroviral drug resistance as a cure for HIV/AIDS.

Abstract
BACKGROUND Human Immunodeficiency Virus (HIV) infection remains a public health concern in many countries. The increased life expectancy in the post-Antiretroviral Therapy (ART) era has led to an increased risk of cardiovascular disease and death among Persons Living with HIV (PLHIV). Hypertension remains a significant risk factor for cardiovascular disease among PLHIV. Some studies have suggested associations between hypertension among PLHIV and HIV-related health factors. OBJECTIVE To determine the prevalence of hypertension among PLHIV on antiretroviral medications and examine its association with HIV-related health factors. METHODS A cross-sectional study was conducted among attendants at an adult HIV clinic. 362 study participants were selected by systematic sampling. Data on hypertension diagnosis, HIV-related health factors, sociodemographic and other traditional cardiovascular risk factors were collected using a standardized questionnaire and patient chart review. Multivariate logistic regression model was used to determine the association between hypertension and HIV-related factors, adjusting for other risk factors for hypertension. RESULTS The mean age of participants was 47.9 years and majority of participants were female (77.1%). 42% of study participants had been on antiretroviral medications for > 10 years. The prevalence of hypertension was 17.4%. Age > 50 years was associated with higher odds of hypertension (aOR: 3.75, 95%CI 1.68, 8.55, p-value: 0.002). BMI in overweight and obese categories, and a history of comorbid medical conditions (diabetes, hyperlipidemia) were also associated with higher odds of hypertension (aOR: 3. 76, 95%CI 1.44, 9.81, p-value: 0.007), (aOR: 3.17, 95%CI 1.21, 8.32, p-value: 0.019) and (aOR: 14.25, 95%CI 7.41, 27.41, p-value: < 0.001) respectively. No HIV-related health factors were associated with hypertension. CONCLUSION Hypertension was a common condition among PLHIV on antiretroviral medications. No HIV-related health factors were associated with hypertension. Traditional risk factors associated with hypertension were increased age > 50 years, increased BMI, and a history of comorbid medical conditions.

Abstract
The establishment of a latency reservoir is the major obstacle for a cure of HIV-1. The shock-and-kill strategy aims to reactivate HIV-1 replication in HIV -1 latently infected cells, exposing the HIV-1-infected cells to cytotoxic lymphocytes. However, none of the latency reversal agents (LRAs) tested so far have shown the desired effect in people living with HIV-1. We observed that NK cells stimulated with a pan-caspase inhibitor induced latency reversal in co-cultures with HIV-1 latently infected cells. Synergy in HIV-1 reactivation was observed with LRAs prostratin and JQ1. The supernatants of the pan-caspase inhibitor-treated NK cells activated the HIV-1 LTR promoter, indicating that a secreted factor by NK cells was responsible for the HIV-1 reactivation. Assessing changes in the secreted cytokine profile of pan-caspase inhibitor-treated NK cells revealed increased levels of the HIV-1 suppressor chemokines MIP1α (CCL3), MIP1β (CCL4) and RANTES (CCL5). However, these cytokines individually or together did not induce LTR promoter activation, suggesting that CCL3-5 were not responsible for the observed HIV-1 reactivation. The cytokine profile did indicate that pan-caspase inhibitors induce NK cell activation. Altogether, our approach might be-in combination with other shock-and-kill strategies or LRAs-a strategy for reducing viral latency reservoirs and a step forward towards eradication of functionally active HIV-1 in infected individuals.

Abstract
Emerging and re-emerging infectious diseases due to RNA viruses cause major negative consequences for the quality of life, public health, and overall economic development. Most of the RNA viruses causing illnesses in humans are of zoonotic origin. Zoonotic viruses can directly be transferred from animals to humans through adaptation, followed by human-to-human transmission, such as in human immunodeficiency virus (HIV), severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and, more recently, SARS coronavirus 2 (SARS-CoV-2), or they can be transferred through insects or vectors, as in the case of Crimean-Congo hemorrhagic fever virus (CCHFV), Zika virus (ZIKV), and dengue virus (DENV). At the present, there are no vaccines or antiviral compounds against most of these viruses. Because proteins possess a vast array of functions in all known biological systems, proteomics-based strategies can provide important insights into the investigation of disease pathogenesis and the identification of promising antiviral drug targets during an epidemic or pandemic. Mass spectrometry technology has provided the capacity required for the precise identification and the sensitive and high-throughput analysis of proteins on a large scale and has contributed greatly to unravelling key protein-protein interactions, discovering signaling networks, and understanding disease mechanisms. In this Review, we present an account of quantitative proteomics and its application in some prominent recent examples of emerging and re-emerging RNA virus diseases like HIV-1, CCHFV, ZIKV, and DENV, with more detail with respect to coronaviruses (MERS-CoV and SARS-CoV) as well as the recent SARS-CoV-2 pandemic.

Abstract
ABSTRACT Survival time in HIV/AIDS patients has increased as a result of improved treatments, but many acquire functional impairments that may necessitate multidisciplinary medical rehabilitation. In the United States, inpatient rehabilitation facilities (IRF) provide this care, but outcomes are not well described in this population. We used the Uniform Data System for Medical Rehabilitation (UDSMR) database to describe 11,051 HIV/AIDS IRF patients; HIV/AIDS patients were grouped according to the following admission criteria: (1) HIV/AIDS as primary reason for admission (n = 225); (2) HIV/AIDS symptomatic comorbidity (n = 6569); and (3) HIV/AIDS asymptomatic comorbidity (n = 4257). We used standard descriptive statistics to summarize demographic, medical, rehabilitation, and discharge setting characteristics by group. When compared to patients with HIV/AIDS as a comorbidity, primary HIV/AIDS patients had worse outcomes. They made less functional change (25.1 versus 29.8 and 28.9, p < .001), went home less (73.8% versus 74.5% and 77.8%, p < .001) and to an acute care hospital more frequently (18.2% versus 13.9% and 10.1%, p < .001). These findings help to characterize the HIV/AIDS patient population who receive inpatient medical rehabilitation, which helps inform clinical care, and highlight the positive impact IRF care can make to minimize functional disability among chronic HIV/AIDS patients and possibly decrease costs of home health care.
