RESUMO

The goal of this clinical research was to determine the relationship between carotid intima-media thickness (cIMT), cardiovascular risk factors, and neuro-cognitive function in people living with HIV (PLHIV) and were on stable combination anti-retroviral therapy (cART). This is a cross-sectional study performed at a single center, including 149 patients who visited the anti-retroviral therapy center of our tertiary care hospital. Among the PLHIV of our research, 62.4% had at least one associated cardiovascular risk factor, and 61.1% of them had abnormally high cIMT (≥ 0.9 mm on any one side, p = 0.035). These factors and being the male gender (p = 0.028) were associated with a greater Framingham 10-year risk percentage. Hypercholesterolemia was observed in 30.9% of the PLHIV and a higher body mass index (≥ 25 kg/m2) was found in 26.8% of them. The cognitive impairment was milder in 71.8% of cases and moderate in 9.4% of PLHIV. The Chi-square test revealed that a higher proportion of participants who had lower HDL-C levels (p = 0.045), smokers (p = 0.029), systolic blood pressure ≥ 140 mmHg (p = 0.012), and lower educational status (p = 0.017) had a poorer cognitive performance. In our sample population, a higher prevalence of elevated cIMT, cardiovascular risk factors, and mild and moderate cognitive deficiency was observed in PLHIV, who were on stable cART. However, routine assessment of the neuropsychological functions and management of modifiable risk factors are not performed in our patients. Further exploration of the relationship between cardiovascular risks, cIMT, and cognitive impairment in PLHIV is essential to formulate the guidelines and delay the onset of neurocognitive disorders in these patients.

RESUMO

OBJECTIVES: We aimed to assess HIV symptoms from the perspective of both patients and HIV specialists and the impact of discontinuing antiretroviral treatment (ART) on symptomology. We gathered opinions from HIV specialists and people living with HIV about ideal ART parameters and treatment satisfaction. METHODS: Ex post-facto cross-sectional surveys were administered to 502 people living with HIV and 101 HIV clinicians in Spain (18 sites). RESULTS: The median age of participants with HIV was 43.2 years, 74.5% were male, and 91.6% had an undetectable viral load. The mean time since initiation of ART was 10.2 years. Between 54% and 67% of people living with HIV reported experiencing nervousness or anxiety, sadness, fatigue, sleep problems, or muscle/joint pain during the preceding 4 weeks. However, only 22%-27% of specialists acknowledged the presence of these symptoms. The most bothersome symptoms were related to mental health or the central nervous system. There were significant differences between the burden of symptoms reported by people living with HIV and those acknowledged by specialists. The symptoms that more frequently caused ART discontinuation were depression, dizziness, and sleep problems. Both people living with HIV and specialists prioritized ART efficacy and low toxicity, but their importance ratings differed for 5 of the 11 ART characteristics assessed. People living with HIV rated their satisfaction with ART at a mean (± standard deviation) of 8.9 ± 1.5 out of 10, whereas HIV specialists rated it lower, at 8.3 ± 0.7 (p < 0.001). CONCLUSIONS: Despite advances in HIV care and treatment, a large proportion of patients still experience symptoms. HIV specialists may not be fully aware of these. People living with HIV and HIV specialists are, overall, satisfied with ART. However, the importance they place on different ART characteristics may vary.

RESUMO

BACKGROUND: There is no systematic review on the prevalence of HIV drug resistance (HIVDR) in Iran. We aimed to estimate the prevalence of HIVDR among people living with HIV (PLHIV) in Iran. We assessed HIVDR prevalence in antiretroviral therapy (ART) naïve PLHIV (i.e., those without a history of ART) and PLHIV receiving ART. METHOD: We systematically searched Scopus, PubMed, Web of Science, Embase, Iranian databases (Iranian Medical Research Information System, Magiran, and Scientific Information Database), the references of studies, and Google Scholar until March 2023. A random-effects model was used to calculate a point estimate and 95% confidence interval (95% CI) for the prevalence of HIVDR in PLHIV. RESULTS: Among 461 potential publications, 22 studies were included in the meta-analysis. The pooled prevalence of acquired HIVDR in PLHIV receiving ART was 34% (95% CI: 19, 50) for nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), 27% (95% CI: 15, 41) for non-nucleoside reverse transcriptase inhibitors (NNRTIs), and 9% (95% CI: 3, 18) for protease inhibitors (PIs). The pooled prevalence of acquired HIVDR in treatment failure PLHIV was 50% (95% CI: 31, 69) for NRTIs, 49% (95% CI: 29, 69) for NNRTIs, 11% (95% CI: 2, 24) for PIs, and 1% (95% CI: 0, 4) for integrase inhibitors (INIs). The pooled prevalence of transmitted HIVDR in ART-naïve people was 3% (95% CI; 1, 6) for NRTIs, 5% (95% CI: 2, 9) for NNRTIs, and 0 for PIs and INIs. CONCLUSION: The prevalence of HIVDR was relatively high in both ART-naïve PLHIV and those receiving ART. Without universal pretreatment HIVDR testing and more frequent routine HIV viral load testing among PLHIV who are on ART, the HIVDR prevalence might increase in PLHIV in Iran.

RESUMO

Little is known about HIV medication concealment behaviors and the effect of medication concealment on antiretroviral therapy (ART) adherence among people with HIV (PWH). This study aims to (1) to describe medication concealment behaviors and factors associated with these behaviors, and (2) assess the association between medication concealment and suboptimal ART adherence. The Florida Cohort Study enrolled adult PWH from community-based clinics around the state from October 2020 to September 2022 (n = 416, 62% aged 50+, 56% male, 44% non-Hispanic Black, 18% Hispanic). Participants responded to questions about sociodemographics, stigma, ART adherence (≥ 85%), symptoms of depression, social networks and disclosure to their networks, and actions to conceal ART to avoid inadvertent disclosure of their HIV status. Analyses were conducted using multivariable logistic regressions models. The most common concealment behavior was hiding ART while having guests over (32%), followed by removing ART labels (26%), and putting ART into a different bottle (16%). Overall, 43% reported ≥ 1 behavior. In multivariable models, depressive symptoms, incomplete disclosure of HIV to close social networks, and not having a close social network were associated with ART concealment. After adjusting for risk factors for suboptimal ART adherence, endorsing hiding medication while having guests was associated with suboptimal ART adherence (aOR 2.87, 95% CI 1.15-7.55). Taking any action and other individual behaviors were not associated. ART concealment behaviors were common but did not consistently negatively influence adherence when accounting for other factors. PWH may want to receive ART medications in ways that ensure privacy and reduce the risk of inadvertent disclosure.

RESUMO

BACKGROUND: There have been few studies on the outcome of acute coronary syndrome (ACS) in human immunodeficiency virus (HIV) infection in the era when antiretroviral therapy (ART) is generalized and most of them have achieved viral suppression. Using claims data, we aimed to assess the mortality after atherosclerotic cardiovascular events in people with HIV (PWH) who maintain optimal adherence to ART. MATERIALS AND METHODS: We used claims data from the National Health Insurance of the Korea to confirm newly diagnosed PWH from 2009 to 2019, and measured ART adherence. ACS and mortality were confirmed in PWH who showed optimal adherence to ART. RESULTS: Among 7,100 PWH with optimal adherence and during 27,387 person-year of follow-up duration, ACS was confirmed in 140 (2.0%) cases, which was 1.3 times greater than statistics of the Korean general population (511.0 vs. 383.1 per 100,000). Acquired immunodeficiency syndrome, hypertension, dyslipidemia, and diabetes mellitus were associated with the development of ACS in PWH with optimal adherence. Mortality was confirmed in 10 cases, which is 7.1% overall and 2.9% when limited to myocardial infarction. It was comparable with the mortality rate of the Korean general population after myocardial infarction (8.9%). CONCLUSION: ACS prevalence was higher in PWH even when optimal adherence was maintained. However, mortality after ACS was comparable to that in the HIV-negative population.

RESUMO

BACKGROUND: Retroviruses are described as a risk factor for chronic neuropathy. However, it is still unknown if they can work as amyotrophic lateral sclerosis triggers. Over the years, some cases of this association have been described with heterogenous disclosures. CASE REPRESENTATION: This study aimed to report a case of HIV and ALS-like neuropathy and briefly discuss peculiarities of clinical aspects, such as physiopathology and treatment options. The patient underwent neurological examination associated with blood tests, electromyography, analysis of cerebrospinal fluid, and imaging studies. DISCUSSION: A non-systematic review was performed in major databases regarding the topic. The case presented mixed upper and lower motor neuron signs and was framed as a probable case of ALS following the present criteria. CONCLUSION: After a short follow-up and viral load cleansing, neurological stabilization was achieved.

RESUMO

Pre- and postexposure prophylaxis for human immunodeficiency virus (HIV) are key to reducing the transmission of this virus. Furthermore, low-toxicity, long-acting formulations provide additional clinical benefits, in particular easier adherence to treatment and prevention. However, breakthrough HIV infections can occur despite the use of pre-exposure prophylaxis (PrEP), mainly due to suboptimal adherence or multi-drug resistant HIV strains. Albeit rare, PrEP breakthrough infections have also been reported in fully adherent patients. Should such breakthrough infection occur in an eligible blood donor, PrEP might suppress viremia and delay antibody seroconversion, thereby masking the infection and increasing the risk of transfusion transmission. This possibility has raised concerns in the blood transfusion community but remains little documented. Therefore, a literature search was performed to assess the state of knowledge on the risk of PrEP breakthrough infection, with a particular focus on the risk of HIV entering the blood supply. Evidently, PrEP breakthrough infections are rare, although the risk is not zero. Moreover, a fraction of individuals - including blood donors - do not disclose PrEP use according to various surveys and measurements of HIV PrEP analytes. Additionally, viremia and seroconversion may remain undetectable or close to the limit of detection for a long time after cessation of PrEP, particularly with long-acting antiretrovirals. Therefore, current recommendations to defer donors for at least 3 months after the last dose of oral PrEP or 2 years for long-acting PrEP appear justified, as they safeguard the blood supply and public trust toward the system. These recommendations help to safeguard blood safety and public trust in the blood supply.

RESUMO

ABSTRACTART-related medication errors occur at high rates in hospitalized people with HIV (PWH), but few studies included modern regimens. As such, we evaluated ART-related medication errors in hospitalized PWH in an era where use of INSTI-based regimens dominate. This multi-center, retrospective cohort included PWH at least 18 years hospitalized in South Georgia, U.S. between March 2016 and March 2018. Of those eligible for inclusion, 400 were randomly selected and included. Three hundred sixty-three inpatient ART-related medication errors occurred in 203 patients during the study period due to incorrect scheduling (44%), an incorrect or incomplete regimen (27%), and drug-drug interactions (27%). Approximately 25% of errors persisted to discharge. Medication errors were more likely to occur in patients receiving NNRTI- or PI-containing multi-tablet regimens, whereas those receiving INSTI-containing multi-tablet regimens were less likely to experience a medication error. ART-related medication errors are less likely in patients receiving INSTI-containing multi-tablet regimens. Ensuring appropriate transition of ART throughout hospitalization remains an area in need of significant improvement.

RESUMO

INTRODUCTION: The effectiveness of human immunodeficiency virus (HIV) post-exposure prophylaxis (PEP) depends on adherence to the protocol, which includes taking antiretrovirals (ARVs) and attending visits. We examined the adherence rate to antiretroviral agents and follow-up visits identifying the associated characteristics of adherence and the reasons for not attending HIV PEP consultations in a specialized service in São Paulo, Brazil. METHODOLOGY: This was a cross-sectional study with health service users who had an indication for PEP due to sexual exposure in an HIV/AIDS service from April to October 2019. The health service users were followed-up throughout the prophylaxis cycle. Adherence was determined through self-reports on antiretroviral agent use and attendance to follow-up consultations. RESULTS: Association measures were employed to identify adherence-related characteristics. The sample analyzed included 91 users. The mean age was 32.5 years old (SD = 9.8). The largest share was white-skinned (49.5%), men who have sex with other men (62.2%), male (86.8%), and undergraduate/graduate students (65.9%). Adherence totaled 56.7% and health insurance was the associated characteristic (p = 0.039). Work (55.9%), using a private service (15.2%), forgetfulness (11.8%) and considering follow-up unnecessary (11.8%) were the main reasons for not attending the follow-up appointments. CONCLUSIONS: Few users do attend HIV PEP consultations. The users without health insurance had the highest adherence percentage whereas work was mentioned as a reason for not attending HIV PEP consultations.

RESUMO

The construction of public policies for the prevention and treatment of HIV/AIDS in Brazil is a history of struggle that unites sanitarians, researchers and activists since the 1980s. An important part of this path is linked to the production and distribution of antiretroviral drugs (ARV), initiatives to reduce the price of ARVs and civil society mobilizations for the guarantee of rights, which contributed to create one of the most successful programs to combat the disease in the country. world. Based on this history, this study aimed to analyze government spending on the acquisition of selected ARVs in the period between 2005 and 2020, making a comparison with international prices, in the light of determinants related to patent disputes, voluntary licensing, PDPs and ARV price reduction initiatives. Among other results, it was possible to observe that there was no immediate relationship between the end of the patent concession and the reduction of prices. Filings of other patent applications and the lack of nationally registered competitors, even after patent expiration, can be significant factors in maintaining high prices.


A construção de políticas públicas para a prevenção e tratamento do HIV/Aids no Brasil é uma história de luta que une sanitaristas, pesquisadores e ativistas desde os anos 1980. Parte importante desse caminho está ligado à produção e distribuição de medicamentos antirretrovirais (ARV), iniciativas de redução do preço dos ARV e mobilizações da sociedade civil pela garantia de direitos, que contribuíram para criar um dos programas mais bem-sucedidos de combate à doença no mundo. Com base nesse histórico, este trabalho teve por objetivo analisar os gastos governamentais na aquisição de ARV selecionados no período entre 2005 e 2020, fazendo uma comparação com preços internacionais, à luz dos determinantes relacionados às disputas patentárias, ao licenciamento voluntário, às PDPs e às iniciativas para redução de preços de ARVs. Entre outros resultados, foi possível observar que não houve uma relação imediata entre o fim da concessão patentária e a redução de preços. Depósitos de outros pedidos de patente e a inexistência de concorrentes registrados nacionalmente, mesmo após a expiração da patente, podem ser fatores significativos para a manutenção de altos preços.

RESUMO

BACKGROUND: Abacavir/dolutegravir/lamivudine has been indicated in Korea since 2015 for treatment of human immunodeficiency virus type 1 (HIV-1) infection in combination. This regulatory post-marketing surveillance (PMS) study evaluated the real-life safety and effectiveness of abacavir/dolutegravir/lamivudine in patients with HIV-1 in clinical practice in Korea. MATERIALS AND METHODS: This open-label post-marketing surveillance examined data from consecutive patients (aged ≥12 years) with HIV-1 infection receiving abacavir/dolutegravir/lamivudine according to locally approved prescribing information; treatment-naïve and treatment-experienced patients were permitted. Data regarding patient demographics, medical history, clinical characteristics, medications (HIV-1 related and concomitant), resource utilization and comorbidities were extracted from patient records over a 1-year treatment period. Outcomes included safety of abacavir/dolutegravir/lamivudine (primary endpoint) and real-life effectiveness according to physician's global assessment and the proportion of patients with plasma HIV-1 RNA count <50 copies/mL at 48 weeks. RESULTS: Of 663 patients treated with abacavir/dolutegravir/lamivudine at 27 centers in Korea (June 2015 - June 2021), 656 were eligible for the safety analyses and 484 for effectiveness analyses. Patients were mostly male (94.8%) mean age was 42.2 ± 14.0 years and mean weight was 68.1 ± 11.0 kg. Adverse events (AEs, n = 656 in total) were mostly mild in severity, with the most common being nasopharyngitis (7.9%), retching (7.5%), headache (4.9%). Of 121 adverse drug reactions (ADRs), the most frequent were retching (4.4%), headache (1.8%) and dizziness (1.7%). Of 55 serious AEs, the most frequent were anogenital warts (1.1%). Of 2 serious ADRs, nothing was unexpected, and both resolved. The risk of experiencing an AE while receiving abacavir/dolutegravir/lamivudine appeared to be especially increased in patients receiving concomitant medications for other conditions. Abacavir/dolutegravir/lamivudine effectively suppressed HIV-1 (96.1% of patients had plasma HIV-1 RNA <50 copies/mL), and 99.0% of patients showed symptom improvement based on physician assessment. CONCLUSION: Results of this PMS study showed that abacavir/dolutegravir/lamivudine administered as highly active antiretroviral therapy was well tolerated and effective in patients with HIV-1 infection.

RESUMO

Se presenta el caso clínico de un paciente asistido en el servicio de Dermatología por tener lesión tumoral gigante en calcáneo derecho de instauración progresiva. La biopsia incisional muestra sarcoma de Kaposi endémico sin afectación visceral. El estadio tan avanzado de la enfermedad propició la evolución tórpida del paciente. El estudio histopatológico estableció el diagnóstico certero de la lesión tumoral; la biopsia fue el método auxiliar que estableció el vínculo necesario entre el examen macroscópico y microscópico de la piel, y la interrelación básico-clínica entre dos disciplinas: Anatomía Patológica y Dermatología.


We present a clinical case of a patient seen in the Dermatology service due to a progressive giant cell tumour in the right calcaneus. Incisional biopsy shows endemic Kaposi's sarcoma without visceral involvement. The advanced stage of the disease led to the torpid evolution of the patient. The histopathological study established the accurate diagnosis of the tumour lesion, the biopsy was the auxiliary method that established the necessary link between the macroscopic and microscopic examination of the skin and the basic and clinical relationship between two disciplines: Pathological Anatomy and Dermatology.

RESUMO

OBJECTIVES: We aimed to explore the experiences of people who initiated rapid antiretroviral therapy (ART) within 7 days of HIV diagnosis, as part of routine care in London. METHODS: Using purposive sampling, 18 in-depth, semistructured interviews were conducted between December 2020 and September 2021 with people who started rapid ART at Barts Health NHS Trust. Participants aged 22-69 years included 15 cisgender men and three cisgender women. Five identified as heterosexual and 13 as gay and bisexual and other men who have sex with men. Ethnic identities: six White Non-UK, five White UK, three Black Caribbean, two South Asian and two East Asian. Interviews explored feelings about the new HIV diagnosis, attitudes to rapid ART including barriers to and facilitators of starting. Thematic analysis of transcribed interviews was undertaken. RESULTS: Four themes were identified: (1) being offered rapid ART is acceptable; (2) it is a way of taking control of their health; (3) the need for information and support and (4) an individualised approach to care. Reasons for starting included getting well, staying well and reducing the likelihood of passing on HIV. Facilitators included being given comprehensive information about treatment and managing potential side-effects and a supportive clinical team. Support specified included a non-judgemental attitude, approachability, reassurance, encouragement and information about peer support. Most participants expressed they could not understand why people would not begin treatment, but suggested needing more time to decide and denial of diagnosis as possible barriers. CONCLUSIONS: To our knowledge, this is the first qualitative study exploring the experiences of people initiating rapid ART in the UK. It was deemed acceptable to an ethnically diverse, predominantly male sample of people newly diagnosed with HIV. Future research should include strategies to recruit a more gender diverse sample and those who declined or stopped rapid ART.

RESUMO

OBJECTIVES: We performed a mixed-methods study to explore the motivations associated with blood donation by donors with known, but undisclosed HIV-positive status and ARV use (HIV+/ARV+), seeking potential strategies to reduce such donations and mitigate risk for blood recipients. Here, we report predominantly the qualitative component. BACKGROUND: A safe and sustainable blood supply is dependent in part, on effective pre-donation donor assessment. We previously described failure by HIV+/ARV+ blood donors to disclose their status. Such donations may lead to transfusion-transmitted HIV. METHODS: The social ecological model provided the conceptual framework for this study. Previously identified HIV+/ARV+ donors were invited to complete a survey (including a validated stigma scale) and qualitative interview, which underwent inductive and deductive thematic analysis. RESULTS: We uncovered two primary motivational paths to HIV+/ARV+ blood donations: privacy and altruism. The latter included a motivation not previously reported in the literature: donating specifically for other people living with HIV (PLWH). The other primary factor was a lack of privacy. These accounts often included donors encountering donation opportunities when accompanied by people to whom they had not and did not plan to disclose their HIV status. Most were highly confident their donations would be identified as HIV-positive and discarded. CONCLUSION: We demonstrated a complex interaction between individual, social, cultural, and structural/policy factors in blood donations by PLWH who take ARV. Recommendations to limit HIV + ARV+ donations include: (1) Targeted communication strategies to increase knowledge among PLWH of their deferral from blood donation-without increasing stigma, and (2) development of procedures to assist those who feel unable to opt-out of donation due to privacy concerns.

RESUMO

Human endogenous retroviruses (HERVs) are retrotransposons that infect human germline cells and occupy 5-8% of the human genome. Their expression, though inhibited by mutation, deletion, and epigenetic mechanisms under normal conditions, is associated with diseases including cancer. This study aimed to clarify the association between HERVs and multiple myeloma (MM) progression. We found that HERV-K envelope (env) and long-term repeat (LTR) expression was statistically significantly higher within plasma cells in MM than in monoclonal gammopathy of undetermined significance or controls. HERV-K env knockdown increased proliferation in the MM.1S cell line and decreased the expression of the tumor suppressor genes TP53 and CDKN1A. TP53 and CDKN1A were highly expressed in MM, and their expression was correlated with HERV-K expression. HERV-K knockdown reduced apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3F, 3G, and 3H expression by 10-20% in MM.1S cells. The anti-retroviral agents nevirapine and nelfinavir suppressed proliferation and increased HERV-K expression in MM cell lines. Our results suggest that HERV-K is involved in MM progression, but its role is likely to go beyond promoting cell proliferation. Clarifying the role of HERV-K in MM will lead to the discovery of novel treatment strategies and supply new insights into MM pathogenesis.

RESUMO

RESUMO Objetivo compreender as perspectivas e desafios no cotidiano de pessoas após a descoberta do viver com VIH em Bissau, Guiné-Bissau, tendo em vista diferentes contextos de vulnerabilidade. Método estudo exploratório-descritivo, que utilizou entrevista semiestruturada com 16 pessoas vivendo com VIH, acompanhadas em um hospital de Bissau. Empregou-se técnica de análise de conteúdo temática. Os relatos dos participantes foram analisados a partir de duas categorias empíricas: A descoberta, os impactos e os desafios de viver com VIH; e Experiência com o antirretroviral: recomeço e perspectivas. Resultados sinalizaram que os desafios iniciam com a revelação do diagnóstico que, geralmente, desperta uma diversidade de sentimentos e comportamentos. O estigma e a discriminação estimulam a adoção do sigilo sobre o status sorológico, resultando na fragilidade de suporte emocional no enfrentamento à soropositividade. A terapia antirretroviral foi vislumbrada como esperança para o enfrentamento da doença. A vulnerabilidade social foi a dimensão que mais se destacou, e violações dos direitos humanos foram constatadas. Conclusão e implicações para a prática o estudo permite compreender as perspectivas, desafios e vulnerabilidades de pessoas que vivem com VIH. O viver com VIH merece atenção especial por parte dos profissionais de saúde que atuam no cuidado dessas pessoas, destacando-se como contribuição a relevância de um cuidado de saúde integral, em que a ética e a subjetividade estejam presentes.


RESUMEN Objetivo este estudio cualitativo tuvo como objetivo comprender perspectivas y desafíos en la vida cotidiana de las personas que viven con VIH en Bissau, Guinea-Bissau, considerando diferentes contextos de vulnerabilidad. Método estudio exploratorio-descriptivo, que utilizó una entrevista semiestructurada con 16 personas que viven con el VIH, seguido en un hospital de Bissau. Se utilizó la técnica de análisis de contenido temático. Los informes de los participantes se analizaron a partir de dos categorías empíricas: El descubrimiento, los impactos y los desafíos de vivir con el VIH; y La experiencia antirretroviral: un nuevo comienzo y perspectivas. Resultados los resultados indicaron que los desafíos comienzan con la divulgación del diagnóstico, que generalmente suscita una diversidad de sentimientos y conductas. El estigma y la discriminación fomentan la adopción del secreto sobre el estado serológico, lo que resulta en un apoyo emocional débil para hacer frente a la seropositividad. La terapia antirretroviral es una esperanza para hacer frente a la enfermedad. La vulnerabilidad social fue la dimensión que más se destacó y se encontraron violaciones a sus derechos humanos. Conclusión e implicaciones para la práctica el estudio permite comprender las perspectivas, los desafíos y las vulnerabilidades de las personas que viven con el VIH. Vivir con VIH merece especial atención por parte de los profesionales de la salud que actúan en el cuidado de estas personas, destacando como aporte la relevancia de la atención integral en salud, en la que la ética y la subjetividad están presentes.


ABSTRACT Objective to understand perspectives and challenges in the daily lives of people after the discovery of living with HIV in Bissau, Guinea-Bissau, considering different contexts of vulnerability. Method an exploratory-descriptive study conducted through semi-structured interviews with sixteen people living with HIV attending a hospital in the city of Bissau. We used the thematic content analysis technique. Participants' reports were analyzed following two empirical categories: Discovery, impacts and challenges of living with HIV; and Experience with antiretroviral therapy: new beginning and perspectives. Results the results indicate that the challenges start with the disclosure of diagnosis, which arouses a diversity of feelings and behaviors. Stigma and discrimination encourage the adoption of confidentiality about serological status, which increases the fragility of emotional support in coping with seropositivity. Antiretroviral therapy was seen as a hope for coping with the disease. Social vulnerability was the dimension that stood out the most, and human rights violations involving people living with HIV were verified. Conclusion and implications for practice the study makes it possible to understand the perspectives, challenges and vulnerabilities of people living with HIV. Living with HIV deserves special attention from health professionals who work in the care of these people, highlighting as a contribution the relevance of comprehensive health care, in which ethics and subjectivity are present.

RESUMO

BACKGROUND: Cytopenias serve as common indicators and crucial predictive tools for evaluating disease progression and therapeutic outcomes in individuals with human immunodeficiency virus (HIV) infection. This study aimed to assess the prevalence of cytopenias and their correlation with the level of immunosuppression in treatment-naive HIV-infected participants after initiating highly active combined antiretroviral drug therapy (cART24). MATERIALS AND METHODS: This prospective study focused on evaluating cytopenia in 44 treatment-naive HIV-infected patients who consented to initiate cART and were consecutively enrolled. The research was conducted at the Nasara HIV Treatment & Care Centre of Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Nigeria, spanning from December 2016 to January 2018. Cytopenias, including anemia, leucopenia, lymphocytopenia, and thrombocytopenia, were defined and assessed according to World Health Organization guidelines. A combination of cross-sectional and longitudinal mixed-design two-step analysis was employed to validate our findings. RESULTS: The median time from enrollment to cART initiation was 7 days, following the universal test and treat protocol. The prevalence of cytopenia was 75% at the baseline before treatment and increased to 84% after cART24 administration. There were no statistically significant differences in the median values of immuno-hematological parameters between baseline and after cART24 initiation (P >0.05). In terms of longitudinal assessment, the prevalence of anemia, leucopenia, lymphopenia, and thrombocytopenia at baseline were 66%, 23%, 0%, and 11%, respectively, and after cART24, the rates were 66%, 29%, 5%, and 20%. Notably, the prevalence of cytopenia correlated with declining CD4+ T cell counts. Among instances of unicytopenia, 58% exhibited isolated anemia, 6% had lone leucopenia, and 6% had solitary thrombocytopenia. Additionally, 27% demonstrated bi-cytopenia, and 3% exhibited pancytopenia. Interestingly, none of the study participants presented with lymphopenia. The most common combination was anemia and thrombocytopenia. Both longitudinal and cross-sectional analytical findings were consistent. CONCLUSION: In treatment-naive HIV-infected individuals, the prevalence of cytopenias, particularly anemia and thrombocytopenia, was substantial and correlated with the degree of immunosuppression as indicated by CD4+ T cell counts. These cytopenias persisted despite initiation of cART24, highlighting the complexity of hematological manifestations in HIV infection. Our study underscores the significant hematopathological impact of HIV and antiretroviral therapy, highlighting the necessity for preventive strategies to mitigate these adverse effects.

RESUMO

SUMMARY OBJECTIVE: The objective of this study was to evaluate cytogenetic changes in individuals submitted to oral human immunodeficiency virus pre-exposure prophylaxis use through the micronucleus test in oral mucosa. METHODS: This study consisted of 37 individuals, of whom 17 comprised the pre-exposure prophylaxis group and 20 comprised the control group. A total of 2,000 cells per slide were analyzed for the determination of micronuclei, binucleation, nuclear buds, and cytotoxicity parameters: pyknosis, karyolysis, and karyorrhexis (KR), in a double-blind manner. The repair index was also evaluated in this setting. RESULTS: In the mutagenicity parameters, the pre-exposure prophylaxis group showed increased frequencies of micronuclei (p=0.0001), binucleation (p=0.001), and nuclear buds (p=0.07). Regarding the cytotoxicity parameters, there was an increase with a statistical difference (p≤0.05) in the karyorrhexis frequency (p=0.001). Additionally, the repair system efficiency decreased in the pre-exposure prophylaxis group. CONCLUSION: These results indicate that individuals undergoing pre-exposure prophylaxis use have geno- and cytotoxicity in oral mucosal cells.

Abstract Objective To assess the effectiveness of an educational booklet to promote healthy lifestyle and antiretroviral compliance in people with HIV. Methods This is a randomized clinical trial at an outpatient clinic in Fortaleza, Ceará, Brazil, with 70 patients in the intervention group and 74 in the control group. People with HIV over 18 years of age, of both sexes, on antiretroviral therapy for more than six months, with a landline or cell phone, and 35 or more points on the Health Literacy Scale were included. Data collection took place in four moments, using the Individual Lifestyle Profile Scale and the Assessment of Antiretroviral Therapy Compliance Questionnaire (Cuestionario para la Evaluación de la Adhesión al Tratamiento Antirretroviral). The control group received routine medical consultation, and the intervention group, in addition to routine consultation, read the booklet in the office, and then took it home. Non-parametric analysis of variance of repeated measures was used for statistics. Results Most participants had an unsatisfactory lifestyle at baseline. The booklet improved patients' lifestyle after two (P<0.001), four (P<0.001) and six months (P<0.001) of intervention, when comparing the different times to baseline and control. There was an improvement in antiretroviral compliance scores in the intervention group when compared to baseline (P<0.001) and control (P<0.001). Conclusion The booklet was effective in promoting a healthy lifestyle and improving antiretroviral compliance in people with HIV, therefore, it can complement outpatient consultations.
