The Role of Electrochemical Sensors in Enhancing HIV Detection
Authors: Xingxing Li, Jiangwei Zhu and Li FuHuman Immunodeficiency Virus (HIV) remains a significant global health challenge, necessitating rapid, sensitive, and accessible diagnostic tools. We examined recent advancements in electrochemical sensors for HIV gene detection, focusing on various sensing strategies, nanomaterial integration, and novel platform designs. Electrochemical sensors have demonstrated remarkable progress in HIV detection, offering high sensitivity and specificity. DNA/RNA-based sensors, aptamer approaches, and nanostructured platforms have detection limits as low as attomolar concentrations. Innovative signal amplification techniques, such as branched DNA amplification and toehold strand displacement reactions, have further enhanced sensitivity. Multiplexed detection systems enable simultaneous quantification of multiple HIV targets and related biomarkers. Integration of microfluidic technologies has improved sample processing and detection efficiency. Paper-based sensors show promise for low-cost, disposable testing platforms suitable for resource-limited settings. While challenges remain in terms of selectivity in complex biological samples and point-of-care applicability, electrochemical sensors hold great potential for revolutionizing HIV diagnostics. Future developments in recognition elements, artificial intelligence integration, and combined sensing modalities are expected to address current limitations and expand the capabilities of these sensors, ultimately contributing to improved HIV management and epidemic control strategies.

Augmenting Adherence: Improving Medication Compliance and Patient Education in Anti-Retroviral Therapy through Graphical Representation
Authors: Neema Tulinge Nsolo, Oliva Heloden Nziku and Bhumika KumarAnti-Retroviral Therapy (ART) is a fundamental principle in the management of Human immunodeficiency virus (HIV) infection, significantly improving the quality of life for individuals living with the virus. However, the success of ART crucially depends on patient adherence to complex medication regimens that come with the therapy. Patients must meticulously adhere to their prescribed treatment plans to maintain viral suppression and prevent the progression of HIV. Medication adherence, a multifaceted challenge in healthcare, becomes particularly entangled within the realm of ART. Patients are often prescribed a combination of antiretroviral medications, each with unique dosing schedules and dietary requirements as instructed by the physician. For individuals with varying levels of health literacy, language proficiency, and cultural backgrounds, comprehending and adhering to these regimens can be overwhelming and challenging. Non-adherence to these medications can result in treatment failure, drug resistance, and compromised health outcomes that burden the healthcare systems. In that perspective, the role of pictograms as visual aids emerges as part and parcel of patient education and counseling within healthcare systems. Pictograms are graphical representations of concepts or actions designed to transcend linguistic and literacy barriers. When used in conjunction with ART, they simplify complex medication instructions, empower patients with knowledge, and improve adherence. Generally, the role of pictograms in supporting medication adherence and patient counseling in antiretroviral therapy is a powerful testament that serves a purpose in bridging communication and literacy gaps within the healthcare systems. By simplifying complex medication regimens, empowering patients with knowledge, and fostering adherence, pictograms contribute to better health outcomes and the overall success of ART. As healthcare providers and systems continue to harness the potential of pictograms, patient education and adherence in the management of HIV and other chronic conditions stand to be greatly enhanced.

The Future of Gene Expression Studies in HIV Research
More LessHuman Immunodeficiency Virus (HIV) damages or interferes with immune cell function and remains a serious worldwide public health concern. Many researchers have studied the virus since its discovery in an effort to better understand its immunopathogenesis and neuropathogenesis. For those who have access to efficient HIV prevention, diagnosis, treatment, and care, HIV infection has now evolved into a chronic illness that can be controlled. Despite a decrease in HIV prevalence in the general population, certain subpopulations continue to exhibit higher-risk behaviors. This work aims to uncover research gaps in HIV gene expression studies, which is crucial in finding a cure. For instance, blood samples are used for most of the gene expression experiments for HIV. However, since there are very few HIV latent reservoir cells in the blood, it can be difficult to identify and quantify them. Furthermore, blood cell populations might not accurately represent the features of reservoir cells found throughout the body. Using HIV reservoir cells from distinct tissue types in gene expression research projects could help us pinpoint the main cause of the latent HIV resilience. Gene expression studies using potential repurposed drug candidates, as well as alternative experimental setups with combinations of antiretroviral therapies, can be utilized in future studies as well. Additionally, large-sample research designs that specifically investigate intestinal disruption in individuals with HIV and associated comorbidities may help us better understand the processes behind HIV.

Comparison of the Effectiveness of Mindfulness-based Cognitive Therapy and Silva-based Relaxation Therapy on Psychological Capital, Social Anxiety, and CD4+ Count in People Living with HIV in Iran
Background/ObjectiveDue to the impact of human immunodeficiency virus (HIV) infection on personal and social life, people living with HIV (PLWH) are faced with several challenges and issues. Therefore, PLWH requires psychological interventions. The study aims were to create a suitable platform for psychological structures that empower them to address their issues effectively. In this regard, we evaluated the effect of Mindfulness-based Cognitive Therapy (MBCT) and Silva-based Relaxation Therapy (SBRT) on Psychological Capital (PsyCap), Social Anxiety (SA), and CD4 count in PLWH.
MethodsThis study employed an intervention-based semi-experimental design. The population consisted of 90 individuals infected with HIV. Participants were divided into two experimental groups receiving MBCT and SBRT, respectively, and one control group, selected randomly. Before and after the intervention, questionnaires and CD4+ tests were administered to the participants. Only two experimental groups received the intervention, while the control group received no training. The appropriate training for each group was conducted twice a week over eight sessions and each session lasted 90 minutes. In the intervention groups, all the people participated in all the group training sessions. No intervention was performed for the participants of the control group, and they only completed the questionnaires in the same period as the intervention groups. “Mindfulness-Based Cognitive Therapy” and “Mind Control” books were used for the implementation of MBCT and SBRT, respectively.
ResultsIt was revealed that a number of male participants constituted the majority with 58 (64.4%) compared to females. Regarding the means of transmission, sexual contact was the most common with 62 (68.8%) compared to other routes. The mean age of the participants was 40.5 ± 10.8 years. For the SBRT group, the mean CD4+ count was higher, with 599.5 ± 290.9 for pre-test and 563.2 ± 366.7 for post-test assessments, compared to other groups. After performing the linear regression analysis, it was found that the variables had no effect on the main outcome, which is CD4 count after the intervention (p-value= 0.27). For the MBCT group, the CD4+ count variable had a p-value = 0.10 (pretest: 447.2 ± 19.5, posttest: 411.9 ± 235.9), for the SBRT group, the CD4+ count variable had a p-value = 0.05 (pretest: 599.5 ± 290.9, posttest: 549 ± 259.9), and the control group, the CD4+ count variable had a p-value = 0.5 (pretest: 445 ± 222.7, posttest: 563.2 ± 366.7).
ConclusionMBCT and SBRT may enhance the mental well-being of PLWH. Therefore, following the interventions, the mean level of SA decreased, and PsyCap increased. Thus, strategies to improve psychological support interventions may have a significant impact on improving the health status of individuals living with HIV, including indicators of SA and PsyCap.

First Report of HPV Genotyping and Distribution in People Living with and Without HIV from Iran and the Middle East
Authors: Faezeh Maleki, Mohammad Farahmand and Hossein KeyvaniAimsIn people living with human immune deficiency (PLHIV), the rates of human papillomavirus (HPV) infection, mixed types, and high-risk (HR) strains increase, while the virus clearance does not occur. Here, we report HPV genotyping in PLHIVs from Iran and the Middle East region for the first time.
MethodsHPV genotyping in referring individuals from different provinces to our laboratory was evaluated over 2023-2024. For this, the HPV types in specimens were detected through the INNO-LiPA HPV genotyping kit. Statistical analysis was conducted with a 95% confidence interval (95%CI) and P < 0.05. Accordingly, 481 subjects from various provinces participated in this study.
ResultsThe rate of HPV infection was 45.7%, of which 14% were HIV-infected women referred from all provinces. The most prevalent types included 6, 51, and 18, but not 16 HR types. Mixed infections in dually infected women were significantly more than in HPV-infected ones. The HPV+/HIV+ subgroup had the lowest median age. The prevalence of HPV types and mixed infection in PLHIVs was congruent with the previous reports, except for the low rate of type 16 infection, perhaps due to the healthy nature of our subjects. Only HIV+/HPV+ cases' age was similar to the previous reports, perhaps because of sample collection and study designs. Among all factors, age and gender affected the HPV type distribution notably.
ConclusionThe current study corroborated the results of many prior reports, demonstrating the considerable impact of HIV status on HPV distribution. The authors recommend implementing a national HPV vaccination and more comprehensive reports of HPV genotyping in PLHIVs.

Identification of a Novel HIV-1 Recombinant Form Comprising CRF01_AE and Subtype C in Hebei Province, China
Authors: Yapeng Guan, Jun Wang and Xinli LuBackgroundCirculating recombinant form (CRF) 01_AE and subtype C are two HIV-1 subtypes. In recent years, novel HIV-1 recombinant forms have become more and more prevalent in China; however, new HIV-1 CRF01_AE/C recombinant forms are less prevalent nationwide.
ObjectiveOur study aimed to investigate new recombinant forms between different HIV-1 subtypes and evaluate their transmission risk among men who have sex with men (MSM) in Hebei, China.
MethodsThe near full-length genome (NFLG) of HIV-1 was identified using the analyses of the phylogenetic tree and gene breakpoints.
ResultsIn the present work, we have reported a novel HIV-1 recombinant form composed of CRF01_AE and subtype C. The NFLG of this CRF01_AE/C form contained eight gene subregions, with four subtype C gene segments inserted into the CRF01_AE backbone, consisting of I CRF01_AE (790–1,171 nt), II subtype C (1,172–1,840 nt), III CRF01_AE (1,841–5,089 nt), IV subtype C (5,090–5,666 nt), V CRF01_AE (5,667–6,317 nt), VI subtype C (6,318–8,586 nt), VII CRF01_AE (8,587–9,246 nt), and VIII subtype C (9,247–9,409 nt). This new recombinant form was identified as CRF140_0107.
ConclusionThe study suggested that it is important to monitor HIV-1 diversity to reduce HIV-1 transmission in China.

Family Support and Depression among Adolescents Living with HIV in Northern Nigeria
BackgroundFamily support is an important component of family-oriented care and a vital element in the care of patients with chronic illnesses, including HIV/AIDS. We investigated the association between perceived family support and depression among adolescents living with HIV in northern Nigeria.
MethodsThis was a cross-sectional study on 125 adolescents (10-19 years of age) presenting for care at a large urban outpatient HIV clinic in Kano, Nigeria. We assessed family support utilizing the Perceived Social Support Family Scale (PSS-Fa) tool, and depression using the Patient Health Questionnaire-9 (PHQ-9) tool. Logistic regression was done to determine the independent relationship between perceived family support and depression.
ResultsApproximately half of the respondents were males (49.6%). The median age (±IQR) of the participants was 16 (± 4) years. The overall prevalence of depression was 56%. More than half (57.6%) of the respondents reported having strong family support. Depression was independently associated with no family support (adjusted odds ratio, aOR = 3.85, 95% confidence interval, CI = 1.10-13.43), weak family support (aOR = 3.16, 95% CI = 1.04-9.63), and feelings of shame about their HIV status (aOR = 5.20, 95% CI = 1.76-15.35).
ConclusionDepression is common among adolescents presenting for HIV care in northern Nigeria and is independently associated with perceived family support and feelings of shame regarding HIV diagnosis. Our findings support routine screening for depression among adolescents with HIV, coupled with the integration of family-oriented care and counseling into routine HIV services for this population.

Latent Tuberculosis Screening and Active Tuberculosis Disease Development in People Living with HIV: A Multicenter Retrospective Cohort Study in Turkiye
BackgroundAbout 10% of individuals with latent tuberculosis infection (LTBI) develop tuberculosis (TB) disease during their lifetime. People living with HIV (PLWH) have a significantly higher risk of developing tuberculosis disease from latent tuberculosis infection (LTBI) compared to those without HIV. Many HIV treatment guidelines recommend screening and treating for LTBI.
ObjectiveThis study aimed to investigate the LTBI screening frequency of PLWH and the rates of tuberculosis disease development during their follow-up.
MethodsA total of 483 PLWH were admitted to 3 research hospitals between January 2005 and April 2020. Patients who were 18 years and older, who did not have active TB disease, and who were followed up regularly were included in the study. Demographic characteristics and laboratory results of the patients, and tuberculin skin test (TST) and/or interferon gamma releasing assay (IGRA) results were recorded. Whether TB developed during the follow-up of the patients or not was recorded.
ResultsA total of 482 PLWH were enrolled in the study, and 429 (89%) of them were male. The mean age of the patients was 37±13 years. The patients were followed for an average of 27.5 months (2-180 months). The mean CD4 count was 381±246/mm3 at the time of diagnosis. A total of 331 patients (68.7%) were screened for latent infection, and 62 (18.7%) of them were diagnosed with LTBI. During the follow-up of the patients, TB disease did not develop in anyone who was not screened for LTBI, while TB disease developed in 4 people who were screened. The mean age of PLWH who developed tuberculosis disease was 54±10 years, while those who did not develop it was 37±13 years, and the difference was statistically significant (p=0.009).
ConclusionScreening for LTBI in PLWH and treating it when positive are recommended in the EACS guidelines. However, some local HIV guidelines recommend latent TB treatment according to ethnicity, CD4 count, and antiretroviral therapy use. Although the mean follow-up period was short, it was found that there was no difference in the development of TB disease in LTBI-positive and negative individuals in our study. For countries that are not on the list of high-burden countries for TB, it may be an option to give latent TB treatment only to selected patients who have lower CD4 counts.
