Human Herpesviruses (HHVs) play a significant role in neurological diseases such as encephalitis and meningitis, adding significant morbidity. This study aims to retrospectively analyze the effect of HHVs on patients with neurological symptoms, focusing on the Herpesviridae family’s contributions to central nervous system (CNS) infections. Methods: This retrospective cohort study included 895 patients suspected of viral CNS infections, utilizing molecular diagnosis via qPCR to identify HHVs in cerebrospinal fluid (CSF) samples. This was conducted at a reference tertiary care hospital for infectious diseases in the western Brazilian Amazon from January 2015 to December 2022, focusing on the Herpesviridae family’s clinical repercussions and of Cytomegalovirus in CNS infections. Results: The findings revealed that 7.5% of the analyzed samples tested positive for HHVs, with Human Cytomegalovirus (HCMV) and Epstein–Barr Virus (EBV) being the most prevalent. A significant association was found between HHVs and neurological diseases such as encephalitis and meningitis, especially among people living with HIV/AIDS (PLWHA), highlighting the opportunistic nature of these viruses. The study underscores the critical role of CSF analysis in diagnosing CNS infections and the complexity of managing these infections in HIV patients due to their immunocompromised status. Conclusions: The results emphasize the need for comprehensive diagnostic approaches and tailored treatment strategies for CNS infections in immunocompromised individuals. The study calls for ongoing research and advancements in clinical practice to improve patient outcomes facing CNS infections, particularly those caused by HHVs. Full article

People living with HIV and AIDS (PLWHA) deserve equitable and high-quality care. Current HIV and AIDS nursing education may not adequately prepare student nurses for the complexities of caring for PLWHA, and the perspectives of student nurses have not been sufficiently revealed in nursing education research. This study aimed to explore the viewpoints of student nurses with AIDS care experience on methods to improve their care willingness for PLWHA and to identify their educational and training needs. A descriptive qualitative study design was employed, interviewing 18 undergraduate student nurses from 14 tertiary hospitals across 7 provinces in China. Content analysis of transcripts revealed insightful suggestions for improving nursing students’ willingness, such as increased HIV and AIDS education and training, psychological preparation, positive role modeling, raising awareness about AIDS patients, and fostering nursing professionalism. Highlighted education and training needs include progress in HIV and AIDS treatment, preventive measures, psychological support for PLWHA, post-exposure protocols, and HIV-infected risk behaviors. These findings highlight the need for HIV and AIDS education, psychological support training, and stigma-reduction strategies. This study provides valuable insights that could inform policymakers, educators, and healthcare providers on preparing future nurses to meet the complex needs of PLWHA. Full article

This study examines HIV/AIDS-associated knowledge and attitudes towards treating disadvantaged communities among predoctoral dental students in U.S. dental schools who have not yet commenced their Community-Based Dental Education (CBDE) training. It also compares the difference in the knowledge and attitudes between students with reported community engagement with PLWHA and those without. Our study comprised 89 predoctoral dental students within their D1–D3 years of dental school who had not yet initiated their Community-Based Dental Education (referred to as pre-CBDE dental students). Their responses were collected via an online survey. The participants were 68% females, 94% heterosexual, and with a mean age (years) of 25.9 ± 3.5 SD. The majority (62%) were in their first (D1) and second (D2) years of dental education. Of the thirty knowledge questions, only five received a minimum of 90% correct responses. Similarly, we found no statistical differences in most of the knowledge/attitude sections between those with and without prior PLWHA exposure. Encouragingly, 90% of our participants reported prior experience working with disadvantaged communities. Early community engagement fosters a sense of professional responsibility towards administering dental care to disadvantaged communities and we propose that it must be encouraged among aspiring dental school students.

A crucial factor in the success of treatment for patients with Human Immunodeficiency Virus (HIV) is adherence to antiretroviral (ARV) therapy among People Living with HIV/AIDS (PLWHA). Adherence issues remain a persisting problem with multifaceted causes. There are many studies on variables related to ARV therapy adherence, but no study has been found on spiritual well-being and distress tolerance in ARV therapy adherence. This study aims to determine the relationship between distress tolerance and spiritual well-being on adherence to ARV therapy in PLWHA. This research used a quantitative approach with a cross-sectional design. The sample collection process followed a consecutive sampling technique, with data gathered from 129 participants at the South Lampung Regional General Hospital located in Indonesia. Data collection was conducted using three questionnaires administered by the interviewer, which assessed distress tolerance using the Miller–Smith Rating Scale For Stress Tolerance (MSRS-ST), evaluated spiritual Well-Being using the Spiritual Well-Being Scale (SWBS), and gauged ARV therapy adherence using the Medication Adherence Rating Scale (MARS). Data analysis using a simple logistic regression with a 95% confidence interval (CI) showed a significant relationship between distress tolerance (p-value 0.002) and spiritual well-being (p-value 0.036) towards ARV therapy adherence in PLWHA. The results of multiple logistic regression yielded distress tolerance as the most dominant and influential variable in this research. Distress tolerance and spiritual well-being impact adherence to ARV therapy in PLWHA. Suggestions for healthcare services should consider these factors to decrease the risk of non-adherence to therapy and inadvertently heighten mortality risk. Full article

Background: Human Immunodeficiency Virus (HIV) infection represents a significant public health concern and, consequently, the incidence of HIV-Associated Neurocognitive Disorder (HAND) has grown over the years. The present study aims to assess HAND with the Montreal Cognitive Assessment (MoCA) in People Living With HIV/AIDS (PLWHA) to find significant associations with cognitive impairment. Methods: The study included 210 PLWHA, aged from 30 to 81 years, of whom, 137 (65.2%) were males. They were assessed at the Immunology Service of the University Hospital of Monserrato, Cagliari, Italy, between November 2022 and April 2023. Results: The sample showed an overall optimal response to antiretroviral therapy, as shown by the excellent levels of CD4+ lymphocytes and HIV RNA copies. A sum of 115 subjects (54.8%) were considered cognitively impaired and the multivariate analysis demonstrated that it was independently associated with duration of infection (OR: 0.96), age (OR: 1.12), alanine aminotransferase (ALT) (OR: 1.02), and depression (OR: 1.33). By dichotomizing the variables, the significance of the association was confirmed for age (65-year threshold) (χ²: 5.142, p = 0.0233) and depression (χ²: 7.834, p = 0.0051). Conclusions: Our study demonstrates that it is hard to find both statistically and clinically significantly associated variables with cognitive impairment in PLWHA, and that the strongest independent association is with depressed mood.

The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) is still one of the main causes of death in sub-Saharan Africa. Antiretroviral therapies (ARTs) have significantly improved the health conditions of people living with HIV/AIDS (PLWHA). Consequently, a significant drop in morbidity and mortality, along with a reduced incidence of opportunistic infections (OIs), has been observed. However, certain atypical and biological profiles emerge in ART patients post-examination. The objective of this study was to identify the risk factors that contributed to the onset of OIs in HIV patients undergoing ART in Gabon. Epidemiological and biological data were obtained from medical records (2017 to 2019) found at the outpatient treatment centre (CTA) of Franceville in Gabon. Samples for blood count, CD4, and viral load analysis at CIRMF were collected from PLWHA suffering from other pathogen-induced conditions. A survey was carried out and data were analysed using Rstudio 4.0.2 and Excel 2007 software. Biological and socio-demographic characteristics were examined concerning OIs through both a univariate analysis via Fisher’s exact tests or chi² (χ²), and a multivariate analysis via logistic regression. Out of the 300 participants initially selected, 223 were included in the study, including 154 (69.05%) women and 69 (30.95%) men. The mean age was 40 (38.6; 41.85), with individuals ranging from 2 to 77 years old. The study cohort was classified into five age groups (2 to 12, 20 to 29, 30 to 39, 40 to 49, and 50 to 77 years old), among which the groups aged 30 to 39 and 40 to 49 emerged as the largest, comprising 68 (30.5%) and 75 (33.6%) participants, respectively. It was noted that 57.9% of PLWHA had developed OIs and three subgroups were distinguished, with parasitic, viral, and bacterial infections present in 18%, 39.7%, and 55.4% of cases, respectively. There was a correlation between being male and having a low CD4 T-cell count and the onset of OIs. The study revealed a high overall prevalence of OIs, and extending the study to other regions of Gabon would yield a better understanding of the risk factors associated with the onset of these infections.

People living with HIV (PLWH) continue to face stigma and discrimination during dental treatment in Brazil. This study aimed to describe the sociodemographic, educational and professional characteristics of dentists working in the Northern Brazilian region and to identify the level of knowledge of these health professionals in relation to the care and management of PLWH using a digital form. Methods: This cross-sectional study was population-based among dentists and was conducted between July and December 2021. A total of 396 dentists were invited using the “snowball” sampling technique and received an anonymous digital form (Google^® Forms platform) composed of four blocks of dichotomous and multiple-choice questions. After signing the informed consent form, dentists were divided into seven groups according to the amount of time that had passed (in years) since they had completed their bachelor’s degree in dentistry. A total of 25 questions referring to sociodemographic, educational and professional factors and knowledge about the dental care of PLWH were asked, and all data were presented as descriptive percentages and then analyzed using the Kappa test. Results: The average age was 31.9 years, and the states of Pará and Amazonas presented better knowledge about the dental care of PLWH. Dental prostheses (62/381-16.3%), orthodontics (57/381-15%) and periodontics (56/381-14.7%) were the most cited dental specialties, and demographic, professional and epidemiological characteristics showed a statistically significant difference regarding knowledge (<0.0001). Conclusions: The knowledge of dentists in Northern Brazil is partially high, although there is some lack of knowledge about the dental care of PLWH. Full article

Low-frequency mutations associated with drug resistance have been related to virologic failure in subjects with no history of pre-treatment and recent HIV diagnosis. In total, 78 antiretroviral treatment (ART)-naïve subjects with a recent HIV diagnosis were selected and followed by CD4+ T lymphocytes and viral load tests to detect virologic failure. We sequenced the basal samples retrospectively using next-generation sequencing (NGS), looking for low-frequency mutations that had not been detected before using the Sanger sequencing method (SSM) and describing the response to ART. Twenty-two subjects developed virologic failure (VF), and thirteen of them had at least one drug-resistance mutation associated with Reverse Transcriptase Inhibitors (RTI) and Protease Inhibitors (PIs) at frequency levels ≤ 1%, not detected previously in their basal genotyping test. No resistance mutations were observed to Integrase Strand Transfer Inhibitors (INSTIs). We identified a possible cause of VF in ART-naïve subjects with low-frequency mutations detected. To our knowledge, this is the first evaluation of pre-existing drug resistance for HIV-1 minority variants carried out on ART-naïve people living with HIV/AIDS (PLWHA) by analyzing the HIV-1 pol gene using NGS in the country.

HIV-infected patients are at particular risk for invasive pneumococcal disease (IPD). We describe cases of IPD in people living with HIV/AIDS (PLWHA) and find associated risk factors for infection and death. Methods: A retrospective case-control study, nested in a cohort, including PLWHA with and without IPD, conducted in Brazil, 2005–2020. Controls were of the same gender/age and seen at the same time/place as cases. Results: We identified 55 episodes of IPD (cases) in 45 patients and 108 controls. The incidence of IPD was 964/100,000 person-years. A total of 42 of 55 (76.4%) IPD episodes presented with pneumonia and 11 (20%) with bacteremia without a focus and 38/45 (84.4%) were hospitalized. Blood cultures were positive in 54/55 (98.2%). Liver cirrhosis and COPD were the only factors associated with IPD in PLWHA in univariate analysis, although no associated factors were found in multivariate analysis. Penicillin resistance was found in 4/45 (8.9%). Regarding antiretroviral therapy (ART), 40/45 (88.9%) cases vs. 80/102 controls (74.1%) were in use (p = 0.07). Patients with HIV and IPD had a higher CD4 count of 267 cells/mm³ compared with the control group, in which it was 140 cells/mm³ (p = 0.027). Pneumococcal vaccination was documented in 19%. Alcoholism (p = 0.018), hepatic cirrhosis (p = 0.003), and lower nadir CD4 count (p = 0.033) were associated with the risk of death in patients with IPD. In-hospital mortality among PLWHA and IPD was 21.1%, and it was associated with thrombocytopenia and hypoalbuminemia, elevated band forms, creatinine, and aspartate aminotransferase (AST). Conclusions: The incidence of IPD in PLWHA remained high despite ART. The vaccination rate was low. Liver cirrhosis was associated with IPD and death. Full article

Background: In Romania, HIV (human immunodeficiency virus) and AIDS (acquired immunodeficiency syndrome) were first acknowledged in 1989. Getting older with HIV/AIDS is now possible due to antiretroviral treatment, but it can bring dental problems due to HIV itself or to the reluctance of dental professionals to treat dental problems. Our study aims to assess the attitudes, knowledge, and practices of Romanian dental professionals regarding aging PLWHA. Methods: An analytical cross-sectional observational survey based on a self-administered questionnaire was conducted for Romanian dental professionals from October 2022 to January 2023. Results: The responders’ group profile was as follows: a mean age of 39.09 ± 0.36 years (limit: 19–75), a majority of 991 (90.01%) from urban dental offices, and 364 (33.06%) with more than twenty years’ experience. A total of 517 (46.95%) responders had an unprofessional attitude and declared that, if possible, they would avoid taking part in performing dental treatments for people living with HIV/AIDS (PLWHA). There were 89 (8.08%) dental professionals that refused to work with PLWHA. Only 363 (32.97%) had worked with one previously. The dental professionals in rural areas refused PLWHA more frequently: 20% (N = 22) of rural dental professionals vs. 6.76% (N = 67) of urban dental professionals refused to work with PLWHA (OR = 0.30; 95% CI: 0.16-.56). The logistic regression applied for the 1101 responders revealed after stepwise selection that the most influential factor for their refusal to work with PLWHA in our study group was being previously exposed to HIV during dental practice (OR = 14.45; 95% CI: 8.55- 24.42; p = 0.000). Conclusions: Dental educators and health care planners should promote the knowledge of prophylaxis and positive attitudes towards the treatment of PLWHA. Successful resolution of these concerns is time consuming and expensive but necessary if dentists are to satisfy their professional obligations to HIV/AIDS patients. Full article

Detainees are one of the most vulnerable populations to human immunodeficiency virus (HIV). This is mostly caused by the lack of knowledge on the topic among the inmates; the lack of prophylaxis; the high percentage of risky behaviors in jail, such as sexual abuse, unprotected sexual intercourses, and injective drug use; and the generally low perception of the risk of transmission. It has also been observed that the problem does not cease to exist at the moment of release, but it also may be aggravated by the weak support system or the total absence of programs for people living with HIV/AIDS (PLWHA) to avoid discontinuation of antiretroviral drugs. Difficulty in providing housing and jobs and, therefore, a form of stability for ex-detainees, also contributes to none adherence to antiretroviral therapy. Among the detainees, there are also categories of people more susceptible to discrimination and violence and, therefore, to risky behaviors, such as black people, Hispanics, transgender people, and men who have sex with men (MSM). We reviewed the literature in order to provide a more complete picture on the situation of PLWHA in jail and to also analyze the difficulties of ex-detainees in adhering to HIV therapy. Full article

Dehydroepiandrosterone (DHEA) is an adrenal steroid converted to potent androgens. This study aimed to discover the association between serum DHEA levels and immunologic response in people with HIV/AIDS (PLWHA). We enrolled patients aged ≥ 18 years who were treated with combination antiretroviral therapy (cART). We measured CD4+ and CD8+ T-cell counts, HIV-RNA titres, and serum DHEA levels. We assigned each patient to a good- or poor-responder group depending on their CD4+ T-cell counts at study enrolment. Participants with CD4+ T-cell counts > 200/µL were assigned to the good-responder group, whilst those with CD4+ T-cell counts < 200/µL were assigned to the poor-responder group. The participants were followed up for 2 years. The poor-responder group showed lower CD4+ T-cell counts and higher HIV PCR titres at their initial HIV diagnosis and in their 2-year follow-up data. Serum DHEA level was lower in the poor-responder group. Multivariable logistic analysis showed that BMI, initial CD4+ T-cell counts, and serum DHEA level were clinical factors associated with poor immunologic responsiveness to cART in PLWHA. Therefore, DHEA may be used as an indicator of the immunological recovery of PLWHA. Full article

Background: Mental disorders linked with dysfunction in the temporal cortex, such as anxiety and depression, can increase the morbidity and mortality of people living with HIV (PLWHA). Expressions of both nucleobindin 1 (NUCB1) and cannabinoid receptor 1 (CNR1) in the neurons have been found to alter in patients with depressive disorder, but whether it is involved in the development of depression in the context of HIV infection is unknown. Objectives To investigate the effects of NUCB1 on depressive disorder among PLWHA and preliminarily explore the underlying molecular mechanisms. Methods: Individuals who were newly HIV diagnosed were assessed on the Hospital Anxiety and Depression scale (HADS). Then SHIV-infected rhesus monkeys were used to investigate the possible involvement of the NUCB1 and the CNR1 protein in depression-like behavior. Results: The prevalence rate of depression among PLWHA was 27.33% (41/150). The mechanism results showing elevated NUCB1 levels in cerebrospinal fluid from HIV-infected patients suffering from depression were confirmed compared to those of HIV-infected patients. Moreover, the immunohistochemical analysis indicated the expression of NUCB1 in the temporal cortex neurons of SHIV-infected monkeys was higher than that of the healthy control. Conversely, CNR1 expression was down-regulated at protein levels. Conclusions: Depression symptoms are common among PLWHA and associate with NUCB1 expression increases, and NUCB1 may be a potential target for depression. Full article

Cyclospora cayetanensis infections remain one of the most common protozoan opportunistic causes of gastrointestinal diseases and diarrhea among people living with HIV and/or AIDS (PLWHA). This study was conducted to provide a summary of the evidence on the global burden of C. cayetanensis infection and associated risk factors among PLWHA. Scopus, PubMed, Science Direct, and EMBASE were searched up to February 2022. All original peer-reviewed original research articles were considered, including descriptive and cross-sectional studies describing C. cayetanensis in PLWHA. Incoherence and heterogeneity between studies were quantified by I index and Cochran’s Q test. Publication and population bias were assessed with funnel plots and Egger’s asymmetry regression test. All statistical analyses were performed using StatsDirect. The pooled prevalence of C. cayetanensis infection among PLWHA was 3.89% (95% CI, 2.62–5.40). The highest prevalence found in South America was 7.87% and the lowest in Asia 2.77%. In addition, the prevalence of C. cayetanensis was higher in PLWHA compared to healthy individuals. There was a relationship between a higher C. cayetanensis prevalence in PLWHA with a CD4 cell count below 200 cells/mL and people with diarrhea. The results show that PLWHA are more vulnerable to C. cayetanensis infection and emphasizes the need to implement the screening and prophylaxis tailored to the local context. Owing to the serious and significant clinical manifestations of the parasite, an early identification of seropositivity is recommended to initiate prophylaxis between PLWHA with a CD4 count ≤200 cells/mL and PLWHA who do not receive antiviral therapy.

Background: Empirical evidence demonstrates the substantial burden of mental illness among people living with HIV and AIDS (PLWHA). Current literature also notes the co-morbidity of these two illnesses and its impact on quality of life and mortality. However, little evidence exists on patient outcomes, such as hospital length of stay or post-discharge status. Methods: A retrospective analysis of National Inpatient Sample data was conducted. The study population was defined as discharges having a primary diagnosis of HIV based on International Classification of Disease, 10th Revision, Clinical Modification (ICD-10-CM) codes in primary diagnosis field. Clinical Classification Software (CCS) codes are used to identify comorbid mental illness. Length of stay was defined as number of days between hospital admission and discharge. Disposition (or post-discharge status) was defined as routine versus not routine. Patient and hospital characteristics were used as control variables. All regression analyses were survey-weighted and adjusted for control variables. Results: The weighted population size (N) for this study was 26,055 (n = 5211). Among primary HIV discharges, presence of any mental illness as a secondary discharge was associated with 12% higher LOS, when compared to a lack of such comorbidity (incidence rate ratio [IRR] = 1.12, 95% confidence interval [CI] = 1.05, 1.22, p < 0.01). Likewise, among primary HIV discharges, those with mental illness had a 21% lower routine disposition, when compared to those without any mental illness (OR = 0.79, 95% CI = 0.68, 0.91, p < 0.001). Conclusion: Our results highlight the need for improved mental health screening and coordinated care to reduce the burden of mental illness among HIV discharges. Full article
