RESUMO

BACKGROUND: Antiretroviral therapy has reduced the incidence and mortality of AIDS-defining malignancies (ADM); however, non-AIDS-defining malignancies (NADM) are a major cause of death among people living with HIV (PLWH) today. Though current guidelines suggest that PLWH should receive the same treatment as the general population, there are limited studies focused on how HIV status affects the prognosis of cancers. The present study aimed to investigate the characteristics and prognosis of malignant diseases among PLWH in Japan. METHODS: Patients with HIV diagnosed with malignant diseases at our institution between 2011 and 2021 were retrospectively reviewed. RESULTS: There were 205 patients who were diagnosed with malignancies. Of these, 87 (42.4%) were diagnosed with ADM and 118 (57.6%) were diagnosed with NADM. Among 69 patients who received chemotherapy for ADM, 24 (34.8%) developed AIDS-defining opportunistic infections during treatment. In contrast, only one (1.8%) of the 56 patients administered chemotherapy for NADM developed AIDS-defining opportunistic infections. Complications of opportunistic infections at diagnosis of malignancies, low CD4+ T-cell count, positive HIV RNA, and nonadministration of antiretroviral therapy were associated with 5-year overall survival among patients with malignant lymphomas. However, the variables associated with HIV did not affect NADM prognosis. CONCLUSIONS: In this analysis, HIV status had a small impact on the prognosis of malignant diseases in PLWH. Few patients with NADM developed AIDS-defining opportunistic infections after receiving chemotherapy.

RESUMO

The African continent reported the least number of COVID-19 cases and deaths of all the continents, although the exact reasons for this are still unclear. In addition, little is known about the immunological profiles associated with COVID-19 mortality in Africa. The present study compared clinical and immunological parameters, as well as treatment outcomes in patients admitted with COVID-19 in Pretoria, South Africa, to determine if these parameters correlated with mortality in this population. The in-hospital mortality rate for the cohort was 15.79%. The mortality rate in people living with HIV (PLWH) was 10.81% and 17.16% in people without HIV (p = 0.395). No differences in age (p = 0.099), gender (p = 0.127) or comorbidities were found between deceased patients and those who survived. All four of the PLWH who died had a CD4+ T-cell count <200 cells/mm3, a significantly higher HIV viral load than those who survived (p = 0.009), and none were receiving antiretroviral therapy. Seven of 174 (4%) patients had evidence of auto-antibodies neutralizing Type 1 interferons (IFNs). Two of the them died, and their presence was significantly associated with mortality (p = 0.042). In the adjusted model, the only clinical parameters associated with mortality were: higher fraction of inspired oxygen (FiO2) (OR: 3.308, p = 0.011) indicating a greater need for oxygen, high creatinine (OR: 4.424, p = 0.001) and lower platelet counts (OR: 0.203, p = 0.009), possibly secondary to immunothrombosis. Overall, expression of the co-receptor CD86 (p = 0.021) on monocytes and percentages of CD8+ effector memory 2 T-cells (OR: 0.45, p = 0.027) was lower in deceased patients. Decreased CD86 expression impairs the development and survival of effector memory T-cells. Deceased patients had higher concentrations of RANTES (p = 0.003), eotaxin (p = 0.003) and interleukin (IL)-8 (p < 0.001), all involved in the activation and recruitment of innate immune cells. They also had lower concentrations of transforming growth factor (TGF)-ß1 (p = 0.40), indicating an impaired anti-inflammatory response. The immunological profile associated with COVID-19 mortality in South Africa points to the role of aberrate innate immune responses.

RESUMO

BACKGROUND: To date there remains much ambiguity in the literature regarding the immunological interplay between SARS-CoV-2 and HIV and the true risk posed to coinfected individuals. There has been little conclusive data regarding the use of CD4 cell count and HIV viral load stratification as predictors of COVID-19 severity in this cohort. METHODS: We performed a retrospective, observational cohort study on people living with HIV (PLWH) who contracted COVID-19 in central and eastern Europe. We enrolled 536 patients from 16 countries using an online survey. We evaluated patient demographics, HIV characteristics and COVID-19 presentation and outcomes. Statistical analysis was performed using SPSS 20.1. RESULTS: The majority of the study cohort were male (76.4%) and 152 (28.3%) had a significant medical comorbidity. Median CD4 cell count at COVID-19 diagnosis was 605 cells/µL [interquartile range (IQR) 409-824]. The majority of patients on antiretroviral therapy (ART) were virally suppressed (92%). In univariate analysis, CD4 cell count <350 cells/µL was associated with higher rates of hospitalization (p < 0.0001) and respiratory failure (p < 0.0001). Univariate and multivariate analyses found that an undetectable HIV VL was associated with a lower rate of hospitalization (p < 0.0001), respiratory failure (p < 0.0001), ICU admission or death (p < 0.0001), and with a higher chance of full recovery (p < 0.0001). CONCLUSION: We can conclude that detectable HIV viral load was an independent risk factor for severe COVID-19 illness and can be used as a prognostic indicator in this cohort.

RESUMO

People living with HIV (PLWH) are particularly vulnerable to SARS-CoV-2. This multicentre prospective cohort study evaluated the long-term immunogenicity and safety of a third homologous dose of Sinovac CoronaVac in PLWH in China. A total of 228 PLWH and 127 HIV-negative controls were finally included and followed up for 6 months. Fewer participants reported mild or moderate adverse reactions, and no serious adverse events were observed. The median levels of neutralizing antibodies (nAbs) and immunoglobulin G against the receptor-binding domain of the spike protein (S-IgG) in PLWH (655.92 IU/mL, IQR: 175.76-1663.55; 206.83 IU/mL, IQR: 85.20-397.82) were comparable to those in control group (1067.16 IU/mL, IQR: 239.85-1670.83; 261.70 IU/mL, IQR: 77.13-400.75), and reached their peak at 4 weeks, exhibiting a delayed peak pattern compared to the 2-week peak in control group. After then, the immune titres gradually decreased over time, but most participants still maintained positive seroconversion at the 6-month mark. Multivariable generalized estimating equation analysis indicated that CD4+T cell count, HIV viral load, and antiretroviral therapy (ART) were independent factors strongly associated with immune response (each p < 0.05). We suggested that PLWH should maintain well-controlled HIV status through ART and receive timely administration of the second booster dose for optimal protection.

RESUMO

BACKGROUND: Despite the success of antiretroviral therapy (ART), people living with HIV (PLWH) suffer from a high burden of pulmonary diseases, even after accounting for their smoking status. Cytotoxic CD8 T-cells are likely implicated in this phenomenon and may act as a double-edged sword. While being essential in viral infection control, their hyperactivation can also contribute to lung mucosal tissue damage. The effects of HIV and smoking on pulmonary mucosal CD8 T-cell dynamics has been a neglected area of research, which we address herein. METHODS: Bronchoalveolar lavage (BAL) fluid were obtained from ART-treated PLWH (median duration of supressed viral load: 9 years; smokers: n = 14; non-smokers: n = 21) and HIV-uninfected controls (smokers: n = 11; non-smokers: n = 20) without any respiratory symptoms or active infection. Lymphocytes were isolated and CD8 T-cell subsets and homing markers were characterized by multiparametric flow cytometry. RESULTS: Both smoking and HIV infection were independently associated with a significant increase in frequencies of total pulmonary mucosal CD8 T-cell. BAL CD8 T-cells were primarily CD69 + expressing CD103 and/or CD49a, at least one of the two granzymes (GzmA/GzmB), and little Perforin. Higher expression levels of CD103, CD69, and GzmB were observed in smokers versus non-smokers. The ex vivo phenotype of GzmA + and GzmB + cells revealed increased expression of CD103 and CXCR6 in smokers, while PLWH displayed elevated levels of CX3CR1 compared to controls. CONCLUSION: Smoking and HIV could promote cytotoxic CD8 T-cell retention in small airways through different mechanisms. Smoking likely increases recruitment and retention of GzmB + CD8 Trm via CXCR6 and CD103. Heightened CX3CR1 expression could be associated with CD8 non-Trm recruitment from the periphery in PLWH.

RESUMO

Depression is one of the most common mental health problems among people living with HIV (PLWH). However, the longitudinal psychological mechanism underlying the link of internalized HIV stigma and depressive symptoms remains a research gap. This study attempted to articulate how and to what extent perceived social support and resilience mediate the longitudinal associations between internalized HIV stigma and depressive symptoms. A sample consisting of 1,098 Chinese PLWH (Mage = 38.63, SD = 9.20; 63.9% male) with a six-month interval and four waves of follow-up was used in the current study. Participants were asked to complete self-report questionnaires. The associations among main study variables were examined via a complete longitudinal mediation approach. Results indicated that the linkage between internalized HIV stigma at T1 and depressive symptoms at T4 was serially mediated by perceived social support at T2 and resilience at T3, and perceived social support at T2 and depressive symptoms at T3 serially mediated the relationship between resilience at T1 and internalized HIV stigma at T4. Depressive symptoms at a previous time point consistently predicted the levels of internalized HIV stigma at subsequent time points. The study highlights the complex interplay between internalized HIV stigma, mental health problems, and protective factors in a longitudinal context. The findings suggest the need to incorporate interventions aimed at enhancing social support and resilience in mental health programs for PLWH, as these factors may interrupt the pathway from internalized HIV stigma to depressive symptoms and potentially improve the overall psychological well-being of this population.

RESUMO

Prior studies demonstrated that perceived social support is negatively associated with behavioral and mental health problems among people living with HIV (PLWH). However, longitudinal data regarding the associations between perceived social support, internalized HIV stigma, future orientation, and depressive symptoms are limited. The current study aimed to investigate the possible indirect relationship between these variables using four-wave follow-up data (6-month intervals) from a sample of 1,098 Chinese PLWH (Mage = 38.63, SD = 9.20, age range: 18-60 years; 63.9% men). All participants were asked to complete an adapted version of Perceived Social Support Scale, Internalized HIV Stigma Scale, Optimism About the Future Scale, and Center of Epidemiological Studies Depression Scale. Results indicated that perceived social support at baseline was negatively related to depressive symptoms at wave 4. Internalized HIV stigma at wave 2 and future orientation at wave 3 indirectly affected the linkage between perceived social support at baseline and depressive symptoms serially over time. This study highlights the essential role of perceived social support in alleviating depressive symptoms among PLWH, and underscores the complex interplay in which internalized HIV stigma and future orientation serially mediated the relationship between perceived social support and depressive symptoms. These findings suggest the need for integrated interventions to enhance social support, address HIV-related stigma, and promote positive future orientation, which could potentially alleviate depressive symptoms and promote mental well-being among PLWH.

RESUMO

Prior research has documented that anticipated HIV stigma may play an important predictive role in medication adherence among people living with HIV (PLWH). However, longitudinal data on the mechanisms underlying this linkage are scarce. The current study aimed to explore the longitudinal mediation association among anticipated HIV stigma, medication adherence support, HIV self-management, and medication adherence. A four-wave sample consisting of 1,098 Chinese PLWH (Mage = 38.63, SD = 9.20; 63.9% male) with a six-month interval was used in the current study. Participants were asked to complete self-report questionnaires. A path analysis model was analyzed. Results indicate that anticipated HIV stigma at baseline was positively related to medication adherence at Time 4 (T4). Medication adherence support at Time 2 (T2) and HIV self-management at Time 3 (T3) serially mediated the anticipated HIV stigma at Time 1 (T1) and medication adherence at T4. These findings provide critical insights into the mediating roles of medication adherence support and HIV self-management in the relationship between anticipated HIV stigma and medication adherence over time. Such an understanding has important implications for the development of tailored interventions and public health strategies aimed at improving medication adherence among PLWH in the context of HIV-related stigma.

RESUMO

OBJECTIVES: The objective of this study was to identify the pathogen spectrum of community acquired pneumonia in people living with HIV (PLWH), and to compare it with a matched HIV negative group in order to reassess therapeutic strategies for PLWH. METHODS: Seventy-three (n = 73) PLWH (median CD4 3-6 months before CAP: 515/µl; SD 309) with community acquired pneumonia (CAP) were matched with 218 HIV-negative CAP controls in a prospective study design. Pathogen identifications used blood culture, samples from the upper and lower respiratory tract (culture and multiplex PCR) and urinary pneumococcal and legionella antigen test. RESULTS: Although the vaccination rate among PLWH with CAP was significantly higher (pneumococcal vaccination: 27.4 vs. 8.3%, p < 0.001; influenza vaccination: 34.2 vs. 17.4%, p = 0.009), pneumococci were found most frequently as pathogen among both PLWH (n = 19/21.3%) and controls (n = 34/17.2%; p = 0.410), followed by Haemophilus influenzae (PLWH, n = 12/13.5%, vs. controls, n = 25 / 12.6%; p = 0.850). Staphylococcus aureus was found equally in 20.2 and 19.2% in PLWH and controls, but infection or colonization could not be distinguished. Mortality during 6-month follow-up was significantly higher for PLWH (5/73, or 6.8%) versus controls (3/218, or 1.4%), however with lower case numbers than previously reported. Typical HIV-associated pathogens such as Pneumocystis jirovecii were found only exceptionally. CONCLUSIONS: Our study underscores the persistent clinical burden of CAP for PLWH. From pathogen perspective, empirical antibiotic treatment for CAP in PLWH on antiretroviral therapy should cover pneumococci and Haemophilus influenzae and may be adopted from valid common recommendations.

RESUMO

BACKGROUND: Our Hospital in Northern Italy assists 3817 people living with HIV (PLWH) and has faced the impact of COVID-19. Little is known about the impact of HIV infection on the risk of post-COVID-19 conditions (PCCs) onset. We aim to assess the incidence of PCC in PLWH and the factors associated with its occurrence. METHODS: We performed a retrospective, observational study including all PLWH > 18 years registered in the Brescia Health Protection Agency database, assessing SARS-CoV-2 burden, vaccination status, socio-demographic, and viro-immunological parameters from February 2020 until May 2022. Persistence of self-reported symptoms (clustered into gastrointestinal, respiratory, osteo-muscular, and neuro-behavioral symptoms) was evaluated after 3 months by a telephone-administered questionnaire. We estimated the associations between all variables and outcomes through univariate and multivariable logistic models. RESULTS: In the study period, 653 PLWH were diagnosed with SARS-CoV-2 infection (17.1%). We observed 19 (2.9%) reinfections, 71 (10.9%) hospitalizations, and 3 (0.5%) deaths. We interviewed 510/653 PLWH (78%), and 178 (PCCs prevalence 34.9%; CI 95% 30.7-39.2) reported persistent symptoms. Asthenia/fatigue was the most reported symptom (60/178), followed by muscular pain (54/178). In the multivariate regression model, there was a lower risk of PCCs in males respect to females (adjusted OR = 0.64; CI 95% 0.99-3.66), while hospitalization during acute infection was associated with an increased the risk of PCCs (adjusted OR = 1.9; CI 95% 0.99-3.66). Notably, no viro-immunological variable modified the PCCs risk onset. CONCLUSIONS: Our study highlights a substantial prevalence of PCCs among PLWH, three months post-SARS-CoV-2 infection, independent of viro-immunological features or vaccination status.

RESUMO

The medicine burden of people living with HIV (PLWH) is unknown. Between 2018 and 2020, participants completed a survey comprising outcome measures for medicine burden (LMQ-3) and stigma experiences (SSCI-8). Participants were HIV+ adults (≥18 years), using antiretrovirals (ARV) with or without non-ARV medicines, recruited via two outpatient clinics in southeast England and online via HIV charities across the UK. Spearman's correlations between medicine burden levels and stigma scores were calculated. Participants were mostly males (72%, 101/141) of mean (SD) age 48.6 (±12.31) years. Total number of medicines ranged from 1-20. High medicine burden was self-reported by 21.3% (30) and was associated with polypharmacy (≥ 5 medicines) (101.52 Vs 85.08, p = 0.006); multiple doses versus once daily regimes (109.31 Vs 85.65, p = 0.001); unemployment (98.23 Vs 84.46, p = 0.004); and ethnicity (97 Vs 86.85, p = 0.041 for non-White versus White participants). A correlation between medicine burden and stigma was observed (r = 0.576, p < 0.001). The LMQ-3 demonstrated adequate construct validity and reliability (domain loadings ranging 0.617-0.933 and Cronbach's α of 0.714-0.932). Assessment of medicine burden and psychosocial stigma in PLWH could enable identification of those needing additional support in future research and practice.

RESUMO

Long-acting injectable antiretroviral therapy (LAI-ART) can offer people living with HIV (PLWH) a promising alternative to daily oral therapy. This article highlights the issues, challenges and conditions related to introducing LAI-ART into the social lives of PLWH and HIV-care practices in Senegal. Semi-structured interviews were conducted with 42 PLWH in two hospital care units in Dakar and with 13 healthcare providers and 6 peer educators. Interviews were transcribed, thematically coded and analysed using a cross-sectional approach. We found three key issues. First, simplifying living with HIV: PLWH respondents perceive LAI-ART as an opportunity to ease the burden associated with taking tablets. This enthusiasm may however be qualified by an ambivalent relationship with injections and is subject to certain conditions. Second, certain constraints linked to the medicalisation of care are to be anticipated, including the obligation to go to the hospital every two months for injections. These findings foreshadow the new management work for medical follow-up expected to fall on PLWH and caregivers. Third, the challenges of introducing LAI-ART in Senegal are to ensure adequate organisation of care and supply and sustainability of the program. These results clarify how to implement programs to introduce LAI-ART into real life in the West African context.

RESUMO

BACKGROUND: Both sleep-related breathing disorders (SRBDs) and HIV infection can interfere with normal sleep architecture, and also cause physical and psychological distress. We aimed to understand the differences in the obstructive patterns, sleep architecture, physical and psychological distress when compared between people living with HIV (PLWH) and matched the severity of SRBDs controls. METHODS: A comparative study using matched case-control design was conducted. Men with HIV infection (case group) were enrolled from 2016 to 2019. A control group with HIV seronegative men were matched for SRBDs severity, and were selected from sleep medicine center database for comparison. RESULTS: The mean age of the 108 men (including 54 cases and 54 matched controls) was 33.75 years. Central-apnea index (CI) was higher in the case group rather than matched controls (mean CI, 0.34 vs. 0.17, p = 0.049). PLWH had a lower mean percentage of stage 3 sleep (10.26% vs. 13.94%, p = 0.034) and a higher percentage of rapid eye movement sleep (20.59% vs. 17.85%, p = 0.011) compared to matched controls. Nocturnal enuresis and sleepiness causing traffic accidents were more frequent complaint in PLWH compared to controls. CONCLUSIONS: Early detected SRBDs and subtypes in PLWH to begin treatment for the underlying cause could reduce the risk of sleepiness-related traffic accidents.

RESUMO

INTRODUCTION: Availability of anti-retroviral treatment has changed HIV in to a manageable chronic disease, making effective self-management essential. However, only a few studies in low- and middle-income countries (LMICs) reported experiences of people living with HIV (PLWH) on self-management. METHODS: This meta-synthesis of qualitative studies investigated perspectives of PLWH in LMICs on self-management. Various databases, including PubMed, EMBASE, EBSCO, and CINHAL, were searched through June 2022. Relevant additional articles were also included using cross-referencing of the identified papers. We used a thematic synthesis guided by the "Model of the Individual and Family Self-Management Theory" (IFSMT). RESULT: PLWH in LIMICs experience a variety of challenges that restrict their options for effective self-management and compromises their quality of life. The main ones include: misconceptions about the disease, poor self-efficacy and self-management skills, negative social perceptions, and a non-patient-centered model of care that reduces the role of patients. The experiences that influenced the ability to practice self-management are summarized in context (the condition itself, physical and environmental factors, individual and family factors) and process factors (knowledge and beliefs, relationship with the health care worker, self-regulation skills and abilities, and social facilitation). Context and process greatly impacted quality of life through the self-management practices of the patients. CONCLUSION AND RECOMMENDATION: PLWH encounter multiple challenges, are not empowered enough to manage their own chronic condition, and their needs beyond medical care are not addressed by service providers. Self-management practice of these patients is poor, and service providers do not follow service delivery approaches that empower patients to be at the center of their own care and to achieve an effective and sustainable outcome from treatment. These findings call for a comprehensive well thought self-management interventions.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) affects almost 10% of the global populace including people living with HIV (PLWH). PLWH acquire CKD from both traditional and HIV-specific CKD risk factors. This study aimed to determine the prevalence of CKD and associated factors among antiretroviral therapy (ART) naïve PLWH in Lagos, Nigeria.  METHODS: This is a secondary data analysis among adult (≥ 18 years) ART-naïve PLWH enrolled at a large ART clinic in Lagos over 6 years. CKD was defined as estimated glomerular filtration rates (eGFR) below 60ml/min/1.73m2 over 3 months. Three estimators [Body surface area corrected Cockcroft Gault (BSA-CG), Modification of Diet in Renal Disease (MDRD), Chronic kidney disease Epidemiology Collaboration (CKD-EPI)] were used to determine the burden of CKD with no race correction factor. Age- and sex-standardised prevalence rates were determined. Cohen Kappa and Spearman correlations were used to compare the estimators. Logistic regressions were applied to identify variables associated with prevalent CKD. RESULTS: Among 2 772 PLWH, the mean age was 38 years with males older than females (p < 0.001). The majority of participants were females (62.1%), married (54.8%), employed (85.7%), had underweight or normal body mass index (BMI) (62.2%), and were diagnosed with World Health Organization (WHO) clinical stages 1 and 2 (55.5%). The age- and sex-standardised prevalence of CKD ranged from 10.0 - 17.6% with the highest Spearman's correlation (0.928) observed with MDRD and CKD-EPI equations. Increasing age [AOR (95% CI), equation] was significantly associated with CKD across all equations [1.09 (1.06 - 1.13), BSA-CG; 1.07 (1.05 - 1.10), MDRD; 1.09 (1.06 -1.12), CKD-EPI]. Other variables associated with CKD [AOR (95% CI), equation] were anaemia [2.50 (1.34 - 4.68), BSA-CG; 1.73 (1.04 - 2.86), MDRD], BMI <25 kg/m2 [3.35 (1.55 - 7.26), BSA-CG; 2.02 (1.18 - 3.46), CKD-EPI], and CD4 counts ≤ 200 cells/µL [2.02 (1.06 - 3.87), BSA-CG]. CONCLUSION: There was a high prevalence of CKD among ART-naïve PLWH at enrollment, which highlights the need to evaluate this population for CKD. Aside increasing age and low CD4 counts, none of the traditional or HIV-specific risk factors were related to CKD diagnosis.

RESUMO

BACKGROUND: Morbidity and mortality due to cardiovascular diseases (CVDs) are high and increasing in low- and middle-income countries. People living with HIV (PLWH) are more likely to experience CVD than members of the general population. Therefore, we aimed to assess whether PLWH were more likely to have previously been screened for cardiovascular disease risk factors (CVDRFs) than people without HIV. METHODS: A population-based, cross-sectional study was conducted among individuals aged 16 to 68 years across 22 communities in Botswana from February to August 2017 as part of a larger community-based cluster randomized HIV treatment-as-prevention trial. Participants were asked if they had been screened for and counselled on cardiovascular disease risk factors (history of hypertension or blood pressure check, blood glucose and cholesterol measurements, weight check and weight control, tobacco smoking and cessation, alcohol use and physical activity) in the preceding 3 years. HIV testing was offered to those with an unknown HIV status. Multiple logistic regression analysis controlling for age and sex was used to assess the relationship between CVDRF screening and HIV status. RESULTS: Of the 3981 participants enrolled, 2547 (64%) were female, and 1196 (30%) were PLWH (93% already on antiretroviral therapy [ART]). PLWH were more likely to report previous screening for diabetes (25% vs. 19%, p < 0.001), elevated cholesterol (17% vs. 12%, p < 0.001) and to have had their weight checked (76% vs. 55%, p < 0.001) than HIV-uninfected participants. PLWH were also more likely to have received counselling on salt intake (42% vs. 33%, p < 0.001), smoking cessation (66% vs. 46%, p < 0.001), weight control (38% vs. 29%, p < 0.001), physical activity (46% vs. 34%, p < 0.001) and alcohol consumption (35% vs. 23%, p < 0.001) than their HIV-uninfected counterparts. Overall, PLWH were more likely to have received screening for and/or counselling on CVDRFs (adjusted odds ratio 1.84, 95% CI: 1.46-2.32, p < 0.001). CONCLUSION: PLWH were almost two times more likely to have been previously screened for CVDRFs than those without HIV, indicating a need for universal scale-up of integrated management and prevention of CVDs in the HIV-uninfected population.

RESUMO

BACKGROUND: Despite the global decline in HIV infections and mortality worldwide, the HIV epidemic is still growing in the MENA region. In the region, People Living with HIV (PLWH) are facing many challenges related to cultural values, norms, and provided services which create significant obstacles to HIV prevention and control efforts. This study aimed to translate, culturally adapt, and validate the "2021 Louisiana Needs Assessment Questionnaire" for use among Egyptians and Arabic-speaking population. METHODS: Arabic translation and cultural adaptation of the questionnaire passed through five stages. The questionnaire was translated forward and backward then an expert committee reviewed the translated version. Another expert committee reviewed the developed version after modification to assess the content validity using the Content Validity Index (CVI). The last step included a cognitive interview of a convenient sample of 50 adult PLWH in five consecutive rounds to assess subjects' understanding of questions and response items and their meanings. RESULTS: Modifications were carried out all through the translation and adaptation process of the questionnaire including used words, nomenclature of services, adding or omitting response items, and ordering of questions and response items. The synthesized Arabic-adapted questionnaire has adequate content validity and all questions are clearly understood by the studied subjects. The calculated Content Validity Index of all questionnaire items ranged from 0.82 to 1. CONCLUSION: The developed culturally adapted questionnaire has adequate content validity/semantic appropriateness. It can be used to assess the needs of PLWH in the MENA region with minor adaptations to fit each country. It can also be used to follow the outcome and impact of implemented programs and services. Further research is recommended to assess its psychometric properties.

RESUMO

Metabolic-dysfunction-associated fatty liver disease (MAFLD) is a comorbidity that generally increases in people living with HIV (PLWH). This condition is usually accompanied by persistent inflammation and premature immune system aging. In this prospective cohort study, we describe a straightforward methodology for quantifying biomarkers of aging, such as DNA methylation and telomere length, in PLWH and in the context of another relevant condition, such as MAFLD. Fifty-seven samples in total, thirty-eight from PLWH and nineteen from non-PLWH participants with or without MAFLD, were obtained and subjected to DNA extraction from peripheral blood mononuclear cells (PBMCs). Global DNA methylation and telomere length quantification were performed using an adapted enzyme-linked immunosorbent assay (ELISA) and qPCR, respectively. The quantification results were analysed and corrected by clinically relevant variables in this context, such as age, sex, and metabolic syndrome. Our results show an increased association of these biomarkers in PLWH regardless of their MAFLD status. Thus, we propose including the quantification of these age-related factors in studies of comorbidities. This will allow a better understanding of the effect of comorbidities of HIV infection and MAFLD and prevent their effects in these populations in the future.

RESUMO

BACKGROUND AND AIMS: Liver disease remains a leading cause of morbidity and mortality among people living with HIV (PLWH). Emerging data suggest that PLWH are at high risk for developing nonalcoholic fatty liver disease (NAFLD). The aim of this review is to examine the current literature and provide an accurate estimate of the prevalence of NAFLD, nonalcoholic steatohepatitis (NASH), and fibrosis, and identify potential risk factors for NAFLD in PLWH. METHODS: We searched PubMed and Embase databases to identify studies reporting the prevalence of NAFLD and/or fibrosis in PLWH monoinfection. We performed a random effects meta-analysis of proportions to estimate the pooled prevalence of NAFLD, NASH, and fibrosis among PLWH monoinfection. We also examined potential risk factors for NAFLD by comparing characteristics of PLWH monoinfection with and without NAFLD. RESULTS: A total of 43 studies, reporting data for 8230 patients, met our eligibility criteria and were included in the meta-analysis. Based on imaging studies the overall pooled prevalence of NAFLD and moderate liver fibrosis (METAVIR ≥ F2) among PLWH monoinfection was 33.9% (95% confidence interval [CI], 29.67%-38.39%), and 12.00% (95% CI, 10.02%-14.12%), respectively. Based on biopsy studies, prevalence of NASH and significant liver fibrosis (stage ≥F2 on histology) was 48.77% (95% CI, 34.30%-63.34%) and 23.34% (95% CI, 14.98%-32.75%), respectively. Traditional metabolic syndrome and HIV-related factors were associated with NAFLD in PLWH. CONCLUSIONS: Our study confirms that the burden of NAFLD, NASH, and fibrosis is high among PLWH monoinfection. Prospective longitudinal studies are needed to delineate NAFLD, NASH, and fibrosis risk factors, and identify early interventions and new therapies for NAFLD in this population.

RESUMO

BACKGROUND: This review aims to assess the status of healthcare disparities among people living with HIV (PLWH) in China and summarize the factors that drive them. METHODS: We searched PubMed, Web of Science, Cochrane Library, Scopus, China National Knowledge Infrastructure (CNKI) and China Wanfang for studies published in English or Chinese. Studies focusing on any disparities in healthcare services among PLWH in China and published between January 2000 and July 2022 were included. RESULTS: In all, 51 articles met the inclusion criteria, with 37 studies reporting HIV-focused care, and 14 reporting non-HIV-focused care. PLWH aged ≥45 years (vs. <45 years), female (vs. male), ethnic minority (vs. Han), and cases attributed to sexual transmission (vs. injecting drug use) were more likely to receive ART. Females living with HIV have higher ART adherence than males. Notably, 20% [95% confidence interval (CI): 9-43%, I2 = 96%] of PLWH reported any illness in the previous 2 weeks without medical consultation, and 30% (95% CI: 12-74%, I2 = 90%) refused hospitalization when needed in the previous year. Barriers to HIV-focused care included inadequate HIV/ART knowledge and treatment side effects at the individual level; and social discrimination and physician-patient relationships at the community/social level. Structural barriers included medical costs and transportation issues. The most frequently reported barriers to non-HIV-focused care were financial constraints and the perceived need for medical services at individual-level factors; and discrimination from physicians, and medical distrust at the community/social level. CONCLUSION: This review suggests disparities in access and utilization of healthcare among PLWH. Financial issues and social discrimination were prominent reasons. Creating a supportive social environment and expanding insurance policies could be considered to promote healthcare equity.
