Abstract
BACKGROUND Scientific evidence indicates that HIV viral suppression to an undetectable level eliminates sexual transmission risk ("Undetectable=Untransmittable" or "U=U"). However, U=U messaging has been met with skepticism among sexual minority men (SMM) and others. In this survey-based experiment, we manipulated messaging about HIV risk and examined reactions and perceived message accuracy among US SMM. METHODS SMM living with HIV (n = 106) and HIV-negative/status-unknown SMM (n = 351) participated in an online survey (2019-2020). Participants were randomly assigned to 1 of 3 messaging conditions, which varied by level of HIV sexual transmission risk associated with an undetectable viral load (No Risk [U=U]/Low Risk/Control). Participants reported reactions, message accuracy, and reasons for perceiving inaccuracy. We coded open-response data (reactions and reasons) into conceptual categories (eg, "Enthusiasm"). We compared reactions, accuracy ratings, and reasons by condition and serostatus. RESULTS In the No Risk Condition, common reactions were Enthusiasm (40.0%), Skepticism/Disagreement (20.0%), and Agreement (19.4%), reactions common to comparison conditions. A higher percentage of HIV-negative/status-unknown participants (24.1%) expressed Skepticism/Disagreement in the No Risk Condition compared with other conditions (3.2%-9.7%). Participants living with HIV were more likely than HIV-negative/status-unknown participants to perceive the message as accurate in all conditions. In the No Risk Condition, common reasons for perceiving inaccuracy were Risk Misstated (46.1%), Oversimplified/Caveats Needed (17.1%), and Personal Unfamiliarity/Uncertainty (14.5%), reasons common to comparison conditions. Across conditions, 10.3% of participants attributed message inaccuracy to undetectable being misdefined. CONCLUSION Most SMM reacted favorably to U=U messaging. However, many-especially HIV-negative/status-unknown SMM-expressed skepticism. Interventions are needed to enhance U=U understanding and acceptance.

The Potential Role of Undetectable = Untransmittable (U = U) in Reducing HIV Stigma among Sexual Minority Men in the US. AIDS Behav 2024; 28:741-757. [PMID: 38285293 PMCID: PMC11043859 DOI: 10.1007/s10461-023-04263-1] [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] [Accepted: 12/26/2023] [Indexed: 01/30/2024]
Abstract
The Undetectable = Untransmittable (U = U) message and its scientific underpinnings have been widely suggested to reduce HIV stigma. However, misunderstanding and skepticism about U = U may prevent this destigmatizing potential from being fully realized. This cross-sectional study examined associations between U = U belief (belief that someone with a sustained undetectable viral load has zero risk of sexually transmitting HIV) and HIV stigma among US sexual minority men. Differences by serostatus and effects of brief informational messaging were also explored. The survey was completed online by 106 men living with HIV and 351 HIV-negative/status-unknown men (2019-2020). Participants were 18-83 years old (M[SD] = 41[13.0]). Most were non-Hispanic White (70.0%) and gay (82.9%). Although nearly all participants (95.6%) were aware of U = U, only 41.1% believed U = U. A greater percentage of participants living with HIV (66.0%) believed U = U compared with HIV-negative/status-unknown participants (33.6%). Among participants living with HIV, U = U belief was not significantly associated with perceived, internalized, or experienced HIV stigma or with viral load prejudice (prejudice against people who have a detectable HIV viral load). Among HIV-negative/status-unknown participants, U = U belief was associated with less frequently enacted HIV discrimination, more positive feelings toward people with an undetectable viral load, and lower personal endorsement of stigmatizing beliefs. Brief informational messaging about U = U did not affect most stigma dimensions and did not favorably affect any. Interventions are needed to correct commonly held, outdated misconceptions about HIV transmission risk. Such initiatives must not only engage people living with HIV but also engage HIV-negative/status-unknown people to maximize the destigmatizing potential of U = U.

Abstract
Background and aim Invasion of the central nervous system by Treponema pallidum can occur at any stage of syphilis. In the event that T. pallidum is not cleared promptly, certain individuals may experience progression to neurosyphilis, which manifests as cognitive and behavioral abnormalities, limb paralysis, and potentially fatal outcomes. Early identification or prevention of neurosyphilis is therefore crucial. The aim of this paper is to conduct a critical and narrative review of the latest information focusing exclusively to the pathogenesis and clinical management of neurosyphilis. Methodology To compile this review, we have conducted electronic literature searches from the PubMed database relating to neurosyphilis. Priority was given to studies published from the past 10 years (from 2013 to 2023) and other studies if they were of significant importance (from 1985 to 2012), including whole genome sequencing results, cell structure of T. pallidum, history of genotyping, and other related topics. These studies are classic or reflect a developmental process. Results Neurosyphilis has garnered global attention, yet susceptibility to and the pathogenesis of this condition remain under investigation. Cerebrospinal fluid examination plays an important role in the diagnosis of neurosyphilis, but lacks the gold standard. Intravenous aqueous crystalline penicillin G continues to be the recommended therapeutic approach for neurosyphilis. Considering its sustained prominence, it is imperative to develop novel public health tactics in order to manage the resurgence of neurosyphilis. Conclusion This review gives an updated narrative description of neurosyphilis with special emphasis on its pathogenesis, susceptibility, diagnosis, treatment, and prevention.
