RESUMEN

Objetivo. Comparar la calidad de vida en personas que viven con infección por el Virus de la Inmunodeficiencia Humana según el modelo de Atención Farmacéutica que reciben en los Servicios de Farmacia Hospitalaria: CMO (capacidad, motivación y oportunidad), versus seguimiento convencional. Método. Estudio longitudinal, prospectivo, multicéntrico, realizado entre octubre-2019 y noviembre-2021 en 14 Servicios de Farmacia Hospitalaria de España. Se incluyeron pacientes mayores de 18 años, que recibían tratamiento antirretroviral y acudían a las consultas de Atención Farmacéutica durante ≥1 año. Se excluyeron aquellos pacientes sin autonomía para completar los cuestionarios previstos. Los centros fueron aleatorizados a seguir utilizando la misma sistemática de trabajo (seguimiento tradicional) o implementar el modelo CMO, utilizando la estratificación, establecimiento de objetivos farmacoterapéuticos, uso de entrevista motivacional, así como el seguimientolongitudinal con nuevas tecnologías. La variable principal fue la diferencia en el número de dimensiones afectadas negativamente, en cada rama, a las 24 semanas, según cuestionario MOS-HIV. En el brazo CMO se registraron las intervenciones más frecuentemente realizadas.Resultados. Se incluyeron 151 pacientes. La mediana de edad fue de 51,3 años. Se encontró mejora significativa de la calidad de vida al final del seguimiento en el grupo CMO, reduciéndose el número de pacientes con dimensiones afectadas negativamente (2/11 vs 8/11). Las intervenciones más frecuentes llevadas a cabo, según la taxonomía, fueron: Motivación (51,7%) y Revisión y validación del TAR (49,4%). Conclusiones. La calidad de vida de los pacientes es superior en aquellos centros que desarrollan Atención Farmacéutica basada en metodología CMO en comparación con el seguimiento tradicional. (AU)


Objective. To compare quality of life, in patients livingwith HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. Method. Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. Results. 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%) Conclusions. The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up. (AU)

RESUMEN

Objetivos. La prevalencia del uso de drogas de abuso es difícil de establecer en mujeres, debido a los estigmas asociados a ello. El objetivo principal fue analizar las posibles diferencias de las intoxicaciones agudas (IA) según el sexo en una muestra de pacientes atendidos en dos servicios de urgencias hospitalarios (SUH). El objetivo secundario fue identificar las variables asociadas a las intoxicaciones graves, definidas de forma arbitraria como las que requerían una atención intensiva médica de más de 12 horas y posterior ingreso hospitalario. Métodos. Estudio retrospectivo en dos SUH que incluyeron pacientes mayores de 18 años atendidos por IA por drogas de abuso, en el periodo comprendido entre el 1 de julio 2020 y el 31 de julio 2023. Se recogieron variables epidemiológicas, clínicas y de laboratorio. Resultados. Se incluyeron 1.032 pacientes, un 18,5% (191) mujeres. La edad media fue de 35 (DE 10) años, con elevada prevalencia de enfermedad mental aguda (32,2%) e infección por VIH (35,7%). El principal motivo de consumo fue lúdico (90,9%). Las principales drogas de abuso fueron cocaína, alcohol y metanfetaminas. El análisis multivariado mostró que únicamente la edad (OR: 1,03, IC 95%: 1,01-1,05, p = 0,003), el VIH (OR: 2,10, IC 95%: 1,29-3,41, p = 0,003), el consumo de benzodiacepinas (OR: 3,48, IC 95%: 2,14-5,66, p < 0,0001), y la ideación autolítica (OR: 1,82, IC 95%: 1,25-3,79, p = 0,004), se asociaron a gravedad de la intoxicación. Conclusiones. Las IA por drogas de abuso en mujeres presentan algunas diferencias en relación a las de los hombres, ya que son más jóvenes y asocian consumo de alcohol con mayor frecuencia. Las campañas de prevención y políticas sanitarias sobre el uso de sustancias deberían tener en cuenta las diferencias en el consumo según el sexo para adaptarlas a la población a las que vayan dirigidas.

Background. The prevalence of street drug abuse is difficult to establish in women because of stigma associated withthe practice. The main objective of this study was to analyze possible differences between men and women in a sample of patients attended for emergencies due to acute poisonings. The secondary aim was to identify variables associated with severe poisonings defined arbitrarily as requiring intensive care for more than 12 hours after hospital admission. Methods. Retrospective study in 2 hospital EDs. We included patients over the age of 18 years attended for street drug poisonings between July 1, 2020, and July 31, 2023. Epidemiologic, clinical, and laboratory variables were analyzed. Results. A total of 1032 patients were studied; 191 (18.5%) were women. The mean (SD) age was 35 years, and the prevalences of acute mental illness and HIV infection were high at 32.2% and 35.7%, respectively. Drug use was recreational in most cases (90.9%). Cocaine, alcohol, and methamphetamines were the substances most often used. Multivariate analysis showed that the factors associated with the seriousness of poisoning were age, with an odds ratio (OR) of 1.03 (95% CI, 1.01-1.05; P = .003); HIV (OR, 2.10; 95% CI, 1.29-3.41; P = .003); use of benzodiazepines (OR, 3.48; 95% CI, 2.14-5.66; P < .0001); and suicidal ideations (OR, 1.82; 95% CI, 1.25-3.79; P = .004). Conclusions. Differences in poisoning characteristics in women were found, probably related to the younger ages of men in the sample and their higher frequency of alcohol consumption. Public health policies and campaigns to prevent drug abuse should take gender differences into consideration in order to adapt messages to the target populations. (AU)

RESUMEN

Background: HIV can infect bronchial epithelial cells rendering individuals susceptible to lung damage. Our objective was to determine the effects of human immunodeficiency virus (HIV) infection on pulmonary function tests. Methods: We performed a meta-analysis after conducting a literature search in PubMed, Embase, Cochrane Library and Virtual Health Library databases from inception to December 31st, 2022. We employed the inverse variance method with a random effects model to calculate the effect estimate as the mean difference (MD) and 95% confidence interval (CI). We calculated the heterogeneity with the I2 statistic and performed a meta-regression analysis by age, sex, smoking, CD4 T-cells count and antiretroviral therapy. We also conducted a sensitivity analysis according to the studies’ publication date, and excluding the study with the greatest weight in the effect. The PROSPERO registry number was CRD42023401105. Results: The meta-analysis included 20 studies, with 7621 living with HIV and 7410 control participants. The pooled MD (95%CI) for the predicted percentage of FEV1, FVC and DLCO were −3.12 (−5.17, −1.06); p=0.003, −1.51 (−3.04, 0.02); p=0.05, and −5.26 (−6.64, −3.87); p<0.001, respectively. The pooled MD for FEV1/FVC was −0.01 (−0.02, −0.01); p=0.002. In all cases, there was a considerable heterogeneity. The meta-regression analysis showed that among studies heterogeneity was not explained by patient age, smoking, CD4 T-cells count or antiretroviral therapy. Conclusion: Pulmonary function tests are impaired in people living with HIV, independently of age, smoking, CD4 T-cells count, and geographical region. (AU)

RESUMEN

INTRODUCTION: Understanding mortality variability by age and cause is critical to identifying intervention and prevention actions to support disadvantaged populations. We assessed mortality changes in two rural South African populations over 25 years covering pre-AIDS and peak AIDS epidemic and subsequent antiretroviral therapy (ART) availability. METHODS: Using population surveillance data from the Agincourt Health and Socio-Demographic Surveillance System (AHDSS; 1994-2018) and Africa Health Research Institute (AHRI; 2000-2018) for 5-year periods, we calculated life expectancy from birth to age 85, mortality age distributions and variation, and life-years lost (LYL) decomposed into four cause-of-death groups. RESULTS: The AIDS epidemic shifted the age-at-death distribution to younger ages and increased LYL. For AHDSS, between 1994-1998 and 1999-2003 LYL increased for females from 13.6 years (95% CI 12.7 to 14.4) to 22.1 (95% CI 21.2 to 23.0) and for males from 19.9 (95% CI 18.8 to 20.8) to 27.1 (95% CI 26.2 to 28.0). AHRI LYL in 2000-2003 was extremely high (females=40.7 years (95% CI 39.8 to 41.5), males=44.8 years (95% CI 44.1 to 45.5)). Subsequent widespread ART availability reduced LYL (2014-2018) for women (AHDSS=15.7 (95% CI 15.0 to 16.3); AHRI=22.4 (95% CI 21.7 to 23.1)) and men (AHDSS=21.2 (95% CI 20.5 to 22.0); AHRI=27.4 (95% CI 26.7 to 28.2)), primarily due to reduced HIV/AIDS/TB deaths in mid-life and other communicable disease deaths in children. External causes increased as a proportion of LYL for men (2014-2018: AHRI=25%, AHDSS=17%). The share of AHDSS LYL 2014-2018 due to non-communicable diseases exceeded pre-HIV levels: females=43%; males=40%. CONCLUSIONS: Our findings highlight shifting burdens in cause-specific LYL and persistent mortality differentials in two populations experiencing complex epidemiological transitions. Results show high contributions of child deaths to LYL at the height of the AIDS epidemic. Reductions in LYL were primarily driven by lowered HIV/AIDS/TB and other communicable disease mortality during the ART periods. LYL differentials persist despite widespread ART availability, highlighting the contributions of other communicable diseases in children, HIV/AIDS/TB and external causes in mid-life and non-communicable diseases in older ages.

RESUMEN

Programmed cell death protein 1 (PD-1) is an immune checkpoint marker commonly expressed on memory T cells and enriched in latently HIV-infected CD4+ T cells. We engineered an anti-PD-1 chimeric antigen receptor (CAR) to assess the impact of PD-1 depletion on viral reservoirs and rebound dynamics in SIVmac239-infected rhesus macaques (RMs). Adoptive transfer of anti-PD-1 CAR T cells was done in 2 SIV-naive and 4 SIV-infected RMs on antiretroviral therapy (ART). In 3 of 6 RMs, anti-PD-1 CAR T cells expanded and persisted for up to 100 days concomitant with the depletion of PD-1+ memory T cells in blood and tissues, including lymph node CD4+ follicular helper T (TFH) cells. Loss of TFH cells was associated with depletion of detectable SIV RNA from the germinal center (GC). However, following CAR T infusion and ART interruption, there was a marked increase in SIV replication in extrafollicular portions of lymph nodes, a 2-log higher plasma viremia relative to controls, and accelerated disease progression associated with the depletion of CD8+ memory T cells. These data indicate anti-PD-1 CAR T cells depleted PD-1+ T cells, including GC TFH cells, and eradicated SIV from this immunological sanctuary.

RESUMEN

Broadly neutralising antibodies (bNAbs) targeting HIV show promise for both prevention of infection and treatment. Among these, 10-1074 has shown potential in neutralising a wide range of HIV strains. However, resistant viruses may limit the clinical efficacy of 10-1074. The prevalence of both de novo and emergent 10-1074 resistance will determine its use at a population level both to protect against HIV transmission and as an option for treatment. To help understand this further, we report the prevalence of pre-existing mutations associated with 10-1074 resistance in a bNAb-naive population of 157 individuals presenting to UK HIV centres with primary HIV infection, predominantly B clade, receiving antiretroviral treatment. Single genome analysis of HIV proviral envelope sequences showed that 29% of participants' viruses tested had at least one sequence with 10-1074 resistance-associated mutations. Mutations interfering with the glycan binding site at HIV Env position 332 accounted for 95% of all observed mutations. Subsequent analysis of a larger historic dataset of 2425 B-clade envelope sequences sampled from 1983 to 2019 revealed an increase of these mutations within the population over time. Clinical studies have shown that the presence of pre-existing bNAb mutations may predict diminished therapeutic effectiveness of 10-1074. Therefore, we emphasise the importance of screening for these mutations before initiating 10-1074 therapy, and to consider the implications of pre-existing resistance when designing prevention strategies.

RESUMEN

INTRODUCTION: In recent years, the expansion of HIV treatment eligibility has resulted in an increase in people with antiretroviral therapy (ART) experience prior to pregnancy but little is known about postpartum engagement in care in this population. We examined differences in disengagement from HIV care after delivery by maternal ART history before conception. METHODS: We analysed data from people living with HIV (aged 15-49) in Khayelitsha, South Africa, with ≥1 live birth between April 2013 and March 2019. We described trends over time in ART history prior to estimated conception, classifying ART history groups as: (A) on ART with no disengagement (>270 days with no evidence of HIV care); (B) returned before pregnancy following disengagement; (C) restarted ART in pregnancy after disengagement; and (D) ART new start in pregnancy. We used Kaplan-Meier curves and proportional-hazards models (adjusted for maternal age, number of pregnancy records and year of delivery) to examine the time to disengagement from delivery to 2 years postpartum. RESULTS: Among 7309 pregnancies (in 6680 individuals), the proportion on ART (A) increased from 19% in 2013 to 41% in 2019. The proportions of those who returned (B) and restarted (C) increased from 2% to 13% and from 2% to 10%, respectively. There was a corresponding decline in the proportion of new starts (D) from 77% in 2013 to 36% in 2019. In the first recorded pregnancy per person in the study period, 26% (95% CI 25-27%) had disengaged from care by 1 year and 34% (95% CI 33-36%) by 2 years postpartum. Individuals who returned (B: aHR 2.10, 95% CI 1.70-2.60), restarted (C: aHR 3.32, 95% CI 2.70-4.09) and newly started ART (D: aHR 2.41, 95% CI 2.12-2.74) had increased hazards of postpartum disengagement compared to those on ART (A). CONCLUSIONS: There is a growing population of people with ART experience prior to conception and postpartum disengagement varies substantially by ART history. Antenatal care presents an important opportunity to understand prior ART experiences and an entry into interventions for strengthened engagement in HIV care.

RESUMEN

BACKGROUND:  The study explored and described the meaning attached to the lived experiences of women living with human immunodeficiency virus (HIV) in the rural context of Zimbabwe. Stigma and discrimination negatively impact one's ability to perform the expected social roles, the quality of life, and the efforts to prevent the spread of HIV and acquired immunodeficiency syndrome (AIDS) and reduce HIV-related mortality. Thus, the study aims to understand the meaning attached to the lived experiences of HIV-positive women living in rural areas or villages of Matabeleland South province in Zimbabwe. METHODS:  The study used a qualitative, descriptive, and exploratory design. Four focus group discussions were conducted with 24 HIV-positive rural women living in Matabeleland South province, Zimbabwe. An Interpretative Phenomenological Analysis (IPA) was adopted to explore and describe the meaning attached to the lived experiences of women living with HIV. RESULTS:  Two interconnected themes were identified in the analysis with their sub-themes. These were: (1) struggle for social belonging, with subthemes - loss of social belonging and reduced access to community-based empowerment opportunities and (2) struggle for maintaining the quality of life with subthemes - lack of need-based community healthcare and food insecurity. CONCLUSION:  Being a woman living with HIV in rural Zimbabwe means a perpetual struggle to maintain one's humanness and quality of life.Contribution: This study's results will support the efforts of the Zimbabwean government to improve the quality of life of HIV-positive women living in rural areas.

RESUMEN

During the COVID-19 pandemic, HIV programs scaled up differentiated service delivery (DSD) models for people living with HIV (PLHIV). We evaluated the effects of COVID-19 on HIV service delivery and viral suppression in facilities in Northern Nigeria, and determined factors associated with viral suppression among adolescents and adults. We analysed a cross-sectional survey data from facility heads, and retrospective, routinely collected patient data from 63 facilities for PLHIV ≥10 years old in care between April 2019-March 2021, defining study periods as "pre-COVID-19" (before April 2020) and "during COVID-19" (after April 2020). For the pre-COVID and the COVID-19 periods we compared uptake of antiretroviral therapy (ART) refills of ≥3 months (MMD3), and ≥6 months (MM6), missed appointments, viral load (VL) testing, VL testing turnaround time (TAT) and viral suppression among those on ART for ≥6 months using two proportions Z-test and t-tests. We fit a multivariable logistic regression model to determine factors associated with maintaining or achieving viral suppression. Of 84,776 patients, 58% were <40 years, 67% were female, 55% on ART for >5 years, 93% from facilities with community-based ART refill, a higher proportion were on MMD3 (95% versus 74%, p<0.001) and MMD6 (56% versus 22%, p<0.001) during COVID-19 than pre-COVID-19, and a higher proportion had VL testing during COVID-19 (55,271/69,630, [84%]) than pre-COVID-19 (47,747/68,934, [73%], p<0.001). Viral suppression was higher during COVID-19 pandemic compared to the pre-COVID era (93% [51,196/55,216] versus 91% [43,336/47,728], p<0.001), and there was a higher proportion of missed visits (40% [28,923/72,359] versus 39% [26,304/67,365], p<0.001) and increased VL TAT (mean number of days: 38 versus 36, p<0.001) during COVID-19 pandemic and pre-COVID period respectively. Factors associated with maintaining or achieving suppression during COVID-19 were receiving MMD3 and MMD6 refills (OR: 2.8 [95% CI: 2.30-3.47] and OR: 6.3 [95% CI: 5.11-7.69], respectively) and attending clinics with community-based ART refill (OR: 1.6 [95% CI: 1.39-1.87]). The program in Northern Nigeria demonstrated resilience during the COVID-19 pandemic and adoption of MMD had a positive impact on HIV care. Though VL TAT and missed clinic visits slightly increased during the pandemic, VL testing improved and viral suppression moved closer to 95%. Adoption of MMD and community-based models of care at scale are recommended for future pandemic preparedness.

RESUMEN

BACKGROUND: Syphilis is an infection caused by the bacteria Treponema pallidum. It is mainly transmitted through oral, vaginal and anal sex, in pregnancy and through blood transfusion. Syphilis develops in primary, secondary, latent and tertiary stages and presents with different clinical features at each stage. Infected patients can remain asymptomatic for several years and, without treatment, can, in extreme cases, manifest as damage in several organs and tissues, including the brain, nervous tissue, eyes, ear and soft tissues. In countries with a high human immunodeficiency virus (HIV) burden, syphilis increases the risk of HIV infections. We report the case of a young HIV-positive black woman who presented with alopecia and hypopigmentation as features of secondary syphilis. CASE PRESENTATION: A virologically suppressed 29-year-old woman on Anti-retroviral Therapy (ART) presented with a short history of generalized hair loss associated with a non-itchy maculopapular rash and skin depigmentation on the feet. Limited laboratory testing confirmed a diagnosis of secondary syphilis. She was treated with Benzathine Penicillin 2.4MU. After receiving three doses of the recommended treatment, the presenting features cleared, and the patient recovered fully. CONCLUSION: This case demonstrates the importance of a high index of clinical suspicion and testing for syphilis in patients presenting with atypical clinical features of secondary syphilis, such as hair loss and hypopigmentation. It also highlights the challenges in diagnosing and clinically managing syphilis in a resource-limited setting.

Human Immunodeficiency Virus (HIV) has continuously been the greatest epidemic for humanity over a period spanning almost five decades. With no specific cure or treatment available to date despite extensive research, the C-C Chemokine Receptor 5, Delta 32 (CCR5 Δ32) allele genetic point mutation plays an imperative role in the prevention of acquired immunodeficiency syndrome (AIDS). This comprehensive study aims to review the induction of the homozygous recessive deletion genotype using the Clustered Regularly Interspaced Short Palindromic Repeats, Cas 9 Enzyme (CRISPR-Cas9), and hematopoietic stem cell transplantation under positive selection pressure for active immunity in seropositive patients' populations as the phenotype. A methodology is proposed to trigger a significant increase in the expression of Delta 32 beneficial mutant alleles within controlled modern healthcare facilities utilizing totipotent stem cells through somatic gene therapy. It acts upon two dysfunctional CCR5 genes, translating mutant G protein-coupled co-receptors, whose primary function is similar to that of C-X-C Motif Chemokine receptor 4 (CXCR4), by blocking the entry of viral RNA into the CD4+ T helper lymphocytes, halting infection and seizing viral life cycle. This modification is endemic in Northern Europe, where it naturally pertains to the Caucasian descent population samples in the form of polymorphism, p (X=0.01), where X is the probability of frequency of complete immunity against HIV-1 in population samples. The epigenetics of the single nucleotide polymorphism (SNP) are analyzed as they play a significant role in immunity distribution. Furthermore, a comparative analysis within the ethical boundaries of CRISPR-Cas9 is conducted to discuss the practical aspects and challenges of the presented methodologies and treatment alternatives. Additionally, the study assembles all available data and summarizes preexisting research while providing a promising solution to this ethical dilemma. Finally, a methodology is devised to answer the question of whether the variant-specific epidemic of AIDS caused by HIV-1 can be cured via artificially inducing immunity by CRISPR-Cas9.

RESUMEN

SUMMARY: Gestational gigantomastia is a rare condition typified by disproportionate bilateral breast enlargement in pregnant women, resulting in skin thinning, ulceration, and bleeding. Less than sixty cases have been documented worldwide, and only one other in South Africa. Pseudo-angiomatous stromal hyperplasia (PASH) is a rare benign proliferation of stromal tissue in a tumorous or diffuse pattern. This, to the best of our knowledge, is the first published case, a 27-year-old human immunodeficiency virus (HIV) positive woman, to present with both conditions concurrently. Medical management with cabergoline was initiated and, seven months post-delivery, a novel Goldilocks mastectomy was performed with acceptable outcomes.

RESUMEN

BACKGROUND: The initiation of clinical trials for messenger RNA (mRNA) HIV vaccines in early 2022 revived public discussion on HIV vaccines after 3 decades of unsuccessful research. These trials followed the success of mRNA technology in COVID-19 vaccines but unfolded amid intense vaccine debates during the COVID-19 pandemic. It is crucial to gain insights into public discourse and reactions about potential new vaccines, and social media platforms such as X (formerly known as Twitter) provide important channels. OBJECTIVE: Drawing from infodemiology and infoveillance research, this study investigated the patterns of public discourse and message-level drivers of user reactions on X regarding HIV vaccines by analyzing posts using machine learning algorithms. We examined how users used different post types to contribute to topics and valence and how these topics and valence influenced like and repost counts. In addition, the study identified salient aspects of HIV vaccines related to COVID-19 and prominent anti-HIV vaccine conspiracy theories through manual coding. METHODS: We collected 36,424 English-language original posts about HIV vaccines on the X platform from January 1, 2022, to December 31, 2022. We used topic modeling and sentiment analysis to uncover latent topics and valence, which were subsequently analyzed across post types in cross-tabulation analyses and integrated into linear regression models to predict user reactions, specifically likes and reposts. Furthermore, we manually coded the 1000 most engaged posts about HIV and COVID-19 to uncover salient aspects of HIV vaccines related to COVID-19 and the 1000 most engaged negative posts to identify prominent anti-HIV vaccine conspiracy theories. RESULTS: Topic modeling revealed 3 topics: HIV and COVID-19, mRNA HIV vaccine trials, and HIV vaccine and immunity. HIV and COVID-19 underscored the connections between HIV vaccines and COVID-19 vaccines, as evidenced by subtopics about their reciprocal impact on development and various comparisons. The overall valence of the posts was marginally positive. Compared to self-composed posts initiating new conversations, there was a higher proportion of HIV and COVID-19-related and negative posts among quote posts and replies, which contribute to existing conversations. The topic of mRNA HIV vaccine trials, most evident in self-composed posts, increased repost counts. Positive valence increased like and repost counts. Prominent anti-HIV vaccine conspiracy theories often falsely linked HIV vaccines to concurrent COVID-19 and other HIV-related events. CONCLUSIONS: The results highlight COVID-19 as a significant context for public discourse and reactions regarding HIV vaccines from both positive and negative perspectives. The success of mRNA COVID-19 vaccines shed a positive light on HIV vaccines. However, COVID-19 also situated HIV vaccines in a negative context, as observed in some anti-HIV vaccine conspiracy theories misleadingly connecting HIV vaccines with COVID-19. These findings have implications for public health communication strategies concerning HIV vaccines.

RESUMEN

INTRODUCTION: Digital health or "e-Health" is a set of applications based on Information and Communication Technologies that can be used to promote self-care and medication adherence in patients with chronic diseases. The aim of this study was to carry out a review of systematic reviews (meta-review) on efficacy studies of e-Health interventions to promote adherence to antiretroviral therapy in people living with HIV/AIDS. METHOD: A review of systematic reviews ("meta-review") was performed using the Medline-PubMed database on efficacy studies of e-Health components to promote adherence to antirretroviral therapy, in patients with HIV/AIDS, proposing a structured search strategy (PICO question). A selection process for systematic reviews was conducted based on inclusion and exclusion criteria. Subsequently, the corresponding data were extracted, and the analysis was accomplished in descriptive tables. RESULTS: A total of 29 systematic reviews were identified, from which 11 were selected. These reviews comprised 55 randomized controlled therapies with different e-Health interventions and enrolled a total of 15,311 HIV/AIDS patients. Studies included a total of 66 comparisons (experimental group vs. control group) in indirect adherence measurements based on different measurement techniques (36 statistically significant); 21 comparisons of viral load measurements (10 statistically significant); and 8 comparisons of CD4+ cell count measurements (3 statistically significant). m-Health was the most studied component followed by the telephone call and e-Learning. CONCLUSIONS: Evidence was found that supports that some e-Health interventions are effective in promoting adherence to antirretroviral therapy and improving health outcomes in patients with HIV/AIDS, although it is identified that more studies are needed for more robust evidence.

RESUMEN

BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention option for those who are most vulnerable to HIV infection, especially young women (YW). Objection by or lack of support from male sexual partners has been shown to impact YW's ability to take PrEP consistently. We explored the views of YW, and male partners and male peers of YW in Siaya County, Western Kenya, to illustrate how men influence, and can support, YW in using PrEP. METHODS: We used Photovoice to capture the views of YW ages 18-24 who were currently or previously enrolled in the DREAMS program and with current or previous experience taking PrEP. We also captured the views of YW's sexual partners and male peers. The YW completed eight photo assignments that focused on identifying factors influencing their PrEP use, and male participants completed four photo assignments focused on identifying ways men support or hinder YW's PrEP use. Photographs were presented and discussed in same- and mixed-gender groups using the SHOWeD method. YW also participated in in-depth interviews. The analysis focused on identifying themes that described men's influence on YW's PrEP adherence and persistence. RESULTS: Among YW, a restricting male influence on PrEP use emerged in the majority of photo assignments such that YW's photographs and discussions revealed that men were more often viewed as barriers than supporters. YW perceived that they had little autonomy over their sexual lives and choice to use PrEP. YW's PrEP use was perceived to be hindered by stigmatizing community narratives that influenced men's support of PrEP use among women. Male participants suggested that men would support YW's PrEP use if PrEP was better promoted in the community and if men were more knowledgeable about its benefits. CONCLUSIONS: A lack of support from male partners and peers and stigmatizing community narratives influence YW's PrEP use. Community-based programs should include education about PrEP specifically for male partners and peers of YW to positively influence PrEP use among YW.

RESUMEN

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.

RESUMEN

Background: Despite endeavors to achieve the Joint United Nations Programme on HIV/AIDS 95-95-95 fast track targets established in 2014 for HIV prevention, progress has fallen short. Hence, it is imperative to identify factors that can serve as predictors of an adolescent's HIV status. This identification would enable the implementation of targeted screening interventions and the enhancement of healthcare services. Our primary objective was to identify these predictors to facilitate the improvement of HIV testing services for adolescents in Ethiopia. Methods: A study was conducted by utilizing eight different machine learning techniques to develop models using demographic and health data from 4,502 adolescent respondents. The dataset consisted of 31 variables and variable selection was done using different selection methods. To train and validate the models, the data was randomly split into 80% for training and validation, and 20% for testing. The algorithms were evaluated, and the one with the highest accuracy and mean f1 score was selected for further training using the most predictive variables. Results: The J48 decision tree algorithm has proven to be remarkably successful in accurately detecting HIV positivity, outperforming seven other algorithms with an impressive accuracy rate of 81.29% and a Receiver Operating Characteristic (ROC) curve of 86.3%. The algorithm owes its success to its remarkable capability to identify crucial predictor features, with the top five being age, knowledge of HIV testing locations, age at first sexual encounter, recent sexual activity, and exposure to family planning. Interestingly, the model's performance witnessed a significant improvement when utilizing only twenty variables as opposed to including all variables. Conclusion: Our research findings indicate that the J48 decision tree algorithm, when combined with demographic and health-related data, is a highly effective tool for identifying potential predictors of HIV testing. This approach allows us to accurately predict which adolescents are at a high risk of infection, enabling the implementation of targeted screening strategies for early detection and intervention. To improve the testing status of adolescents in the country, we recommend considering demographic factors such as age, age at first sexual encounter, exposure to family planning, recent sexual activity, and other identified predictors.

RESUMEN

Since the identification of human immunodeficiency virus type 1 (HIV-1) in 1983, many improvements have been made to control viral replication in the peripheral blood and to treat opportunistic infections. This has increased life expectancy but also the incidence of age-related central nervous system (CNS) disorders and HIV-associated neurodegeneration/neurocognitive impairment and depression collectively referred to as HIV-associated neurocognitive disorders (HAND). HAND encompasses a spectrum of different clinical presentations ranging from milder forms such as asymptomatic neurocognitive impairment or mild neurocognitive disorder to a severe HIV-associated dementia (HAD). Although control of viral replication and suppression of plasma viral load with combination antiretroviral therapy has reduced the incidence of HAD, it has not reversed milder forms of HAND. The objective of this review, is to describe the mechanisms by which HIV-1 invades and disseminates in the CNS, a crucial event leading to HAND. The review will present the evidence that underlies the relationship between HIV infection and HAND. Additionally, recent findings explaining the role of neuroinflammation in the pathogenesis of HAND will be discussed, along with prospects for treatment and control.

RESUMEN

BACKGROUND: Modelling studies have indicated that approximately 20% of all tuberculosis (TB) cases may suffer from diabetes mellitus (DM). DM increases the risk of developing active TB disease by 2-3 times. People living with HIV (PLHIV) are more likely to develop TB disease, and TB is a leading cause of hospitalization and death among PLHIV. Despite the substantial burden of DM and HIV in India, few studies have evaluated the prevalence of DM and HIV among active cases of TB, and its impact on the treatment outcome for TB. This study evaluated the burden of HIV and DM in TB cases from Odisha during 2019, and its impact on the TB treatment outcome. METHODS: The study utilized data on TB patients of Odisha during 2019, from the NIKSHAY portal, the health management information system (HMIS) of TB in India. This is a retrospective observational registry-based cohort study, which evaluated a linkage between socio-demographic predictors, clinical diagnostic and treatment predictors, time of treatment predictors, and co-morbidity with TB. Data were retrieved electronically in Microsoft-Excel and analysis was done using STATA 16 (StataCorp. 2019, College Station, TX: StataCorp LLC). RESULTS: Data for 47,831 TB cases of Odisha as study population was extracted from the Nikshay application for the year 2019. The highest prevalence (31.1%, 14,863/47,831) of TB was observed among young participants aged 15-30 years, whereas the prevalence was least among children <14 years (4.4%, 2124/47,831). Males had a higher prevalence of TB (66.7%, 31,878/47,831). Of the 47,831 TB cases included in the study, 7.6% (3659/47,831) had diabetes mellitus (DM), along with TB. 1.2% (571/47,831) had HIV along with TB, while only 0.08% (37/47,831) had both DM and HIV along with TB. 88.2% (3148/3569) of cases with DM and TB had a favorable outcome, compared to 82.3% (449/541) of cases with HIV and TB. People with TB who did not have DM had a significantly higher favorable outcome (OR 1.6, 95% CI 1.5-1.8) compared to those with TB and DM. Similarly, TB cases who did not have HIV infection had a significantly higher favorable outcome (OR 2.4, 95% CI 1.9-3.0) compared to those with TB and HIV. CONCLUSION: Our study showed that presence of DM and/or HIV in TB patients had an impact on the TB treatment outcome. There is a crucial need to prevent comorbidities such as DM and HIV from occurring and to prioritize early diagnosis and management of these conditions.
