RESUMEN

Although highly active antiretroviral therapy (HAART) has changed infection with human immunodeficiency virus (HIV) from a diagnosis with imminent mortality to a chronic illness, HIV positive patients who do not develop acquired immunodeficiency syndrome (AIDs) still suffer from a high rate of cardiac dysfunction and fibrosis. Regardless of viral load and CD count, HIV-associated cardiomyopathy (HIVAC) still causes a high rate of mortality and morbidity amongst HIV patients. While this is a well characterized clinical phenomena, the molecular mechanism of HIVAC is not well understood. In this review, we consolidate, analyze, and discuss current research on the intersection between autophagy and HIVAC. Multiple studies have linked dysregulation in various regulators and functional components of autophagy to HIV infection regardless of mode of viral entry, i.e., coronary, cardiac chamber, or pericardial space. HIV proteins, including negative regulatory factor (Nef), glycoprotein 120 (gp120), and transactivator (Tat), have been shown to interact with type II microtubule-associated protein-1 ß light chain (LC3-II), Rubiquitin, SQSTM1/p62, Rab7, autophagy-specific gene 7 (ATG7), and lysosomal-associated membrane protein 1 (LAMP1), all molecules critical to normal autophagy. HIV infection can also induce dysregulation of mitochondrial bioenergetics by altering production and equilibrium of adenosine triphosphate (ATP), mitochondrial reactive oxygen species (ROS), and calcium. These changes alter mitochondrial mass and morphology, which normally trigger autophagy to clear away dysfunctional organelles. However, with HIV infection also triggering autophagy dysfunction, these abnormal mitochondria accumulate and contribute to myocardial dysfunction. Likewise, use of HAART, azidothymidine and Abacavir, have been shown to induce cardiac dysfunction and fibrosis by inducing abnormal autophagy during antiretroviral therapy. Conversely, studies have shown that increasing autophagy can reduce the accumulation of dysfunctional mitochondria and restore cardiomyocyte function. Interestingly, Rapamycin, a mammalian target of rapamycin (mTOR) inhibitor, has also been shown to reduce HIV-induced cytotoxicity by regulating autophagy-related proteins, making it a non-antiviral agent with the potential to treat HIVAC. In this review, we synthesize these findings to provide a better understanding of the role autophagy plays in HIVAC and discuss the potential pharmacologic targets unveiled by this research.

RESUMEN

Background: There is a limited research on predictive models of fat mass ratio (FMR) in people living with human immunodeficiency virus (HIV) (PWH). This study aimed to develop models considering anthropometric and health-related factors to predict and validate FMR in PWH regardless of sex. Methods: One hundred and six Brazilian PWH (46.4±9.8 years) were evaluated for body composition using dual-energy X-ray absorptiometry (DXA), body circumference (BC), and skinfold thicknesses (SKs). FMR predictive models were developed using stepwise linear regression, and their agreement with DXA was assessed using Bland-Altman plots. Cross-validation was performed using the predicted residual error sum of squares (PRESS) method. Results: Six FMR estimation models were developed for PWH, with adjusted R2 ranging from 0.43 to 0.72, standard error of the estimate (SEE) from 0.16% to 0.22%, and 95% confidence interval (CI) from 1.03 to 1.15. Model 6, including thigh SK, waist BC, therapy duration, subscapular SK, education years, and abdominal SK, exhibited the highest determination power (R2 adjusted 0.72, SEE 0.16%, and 95% CI: 1.06-1.15). The agreement between DXA-based FMR and predictive models showed minimal bias (-0.03 to +0.04) and narrower limits of agreement, particularly for the top-performing model (-0.33 to +0.30). Model 6 exhibited a high adjusted Q2PRESS (0.70) and low SPRESS (0.17). Conclusions: Our predictive models advance the study of body composition in PWH by consolidating the use of anthropometry for diagnosing and monitoring lipodystrophy regardless of sex.

RESUMEN

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.

RESUMEN

BACKGROUND: Although indicator condition (IC)-guided HIV testing (IC-HIVT) is effective at facilitating timely HIV diagnosis, research on IC categories and the related HIV risk in Taiwan is limited. To improve the adoption and spread of IC-HIVT in Taiwan, this study compared the IC categories of people living with HIV (PLWH) and non-HIV controls and investigated delays in the diagnosis of HIV infection. METHODS: This nationwide, retrospective, 1:10-matched case-control study analyzed data from the Notifiable Diseases Surveillance System and National Health Insurance Research Database to evaluate 42 ICs for the 5-year period preceding a matched HIV diagnostic date from 2009 to 2015. The ICs were divided into category 1 ICs (AIDS-defining opportunistic illnesses [AOIs]), category 2 ICs (diseases associated with impaired immunity or malignancy but not AOIs), category 3 ICs (ICs associated with sexual behaviors), and category 4 ICs (mononucleosis or mononucleosis-like syndrome). Logistic regression was used to evaluate the HIV risk associated with each IC category (at the overall and annual levels) before the index date. Wilcoxon rank-sum test was performed to assess changes in diagnostic delays following an incident IC category by HIV transmission routes. RESULTS: Fourteen thousand three hundred forty-seven PLWH were matched with 143,470 non-HIV controls. The prevalence results for all ICs and category 1-4 ICs were, respectively, 42.59%, 11.16%, 15.68%, 26.48%, and 0.97% among PLWH and 8.73%, 1.05%, 4.53%, 3.69%, and 0.02% among non-HIV controls (all P < 0.001). Each IC category posed a significantly higher risk of HIV infection overall and annually. The median (interquartile range) potential delay in HIV diagnosis was 15 (7-44), 324.5 (36-947), 234 (13-976), and 74 (33-476) days for category 1-4 ICs, respectively. Except for category 1 for men who have sex with men, these values remained stable across 2009-2015, regardless of the HIV transmission route. CONCLUSIONS: Given the ongoing HIV diagnostic delay, IC-HIVT should be upgraded and adapted to each IC category to enhance early HIV diagnosis.

RESUMEN

Background: An estimated 301 million people worldwide suffer from anxiety disorders. People living with HIV/AIDS (PLWHA) are particularly prone to anxiety disorders that could interfere with the important developmental process in an individual's development and ultimately result in a wide range of negative mental, physical, and psychosocial consequences, as well as poor quality of life in those population groups. Early intervention for anxiety disorders can reverse some of the physical damage caused by anxiety. However, based on systematic reviews and meta-analyses, the specific prevalence of anxiety disorders in PLWHA remains unknown. Method: We conducted a literature search on PubMed, Embase, and Web of Science up to 22 October 2022. A random-effects meta-analysis was used to pool prevalence rates from the included studies. Sensitivity and subgroup analyses were performed to identify the possible sources of heterogeneity and to compare the prevalence estimates across groups. The Joanna Briggs Institute's Quality Assessment Checklist was used to assess the quality of the included studies. Cochran's Q and I2 tests were used to assess the between-study heterogeneity. Results: Ten studies with a total of 238,570 cases were included for the final analysis. Results showed that 15.5% of HIV/AIDS patients had anxiety disorders. The prevalence was higher in females (20.8%) than males (20.7%). The mean age of PLWHA with anxiety disorders was 46.58 ± 11.15 years in these included studies. The subgroup analyses showed significant higher prevalence in non-heterosexual (32.1%). Conclusion: We attempted to quantify literature that could allow for stronger inferences to be made regarding the significantly higher prevalence of anxiety disorders in PLWHA, a finding that suggests the imperativeness of intervention strategies to alleviate suffering and reduce the probable negative ramifications.

RESUMEN

BACKGROUND: Experience with lung transplantation (LT) in patients with human immunodeficiency virus (HIV) is limited. Many studies have demonstrated the success of kidney and liver transplantation in HIV-seropositive (HIV+) patients. Our objective was to conduct a national registry analysis comparing LT outcomes in HIV+ to HIV-seronegative (HIV-) recipients. METHODS: The United Network for Organ Sharing database was queried to identify LTs performed in adult HIV+ patients between 2016 and 2023. Patients with unknown HIV status, multiorgan transplants, and redo transplants were excluded. The primary endpoints were mortality and graft rejection. Survival time was analyzed using Kaplan-Meier analysis. RESULTS: The study included 17 487 patients, 67 of whom were HIV+. HIV+ recipients were younger (59 vs. 62 years, p = .02), had higher pulmonary arterial pressure (28 vs. 25 mm Hg, p = .04), and higher lung allocation scores (47 vs. 41, p = .01) relative to HIV- recipients. There were no differences in graft/recipient survival time between groups. HIV+ recipients had higher rates of post-transplant dialysis (18% vs. 8.4%, p = .01), but otherwise had similar post-transplant outcomes to HIV-recipients. CONCLUSIONS: This national registry analysis suggests LT outcomes in HIV+ patients are not inferior to outcomes in HIV- patients and that well-selected HIV+ recipients can achieve comparable patient and graft survival rates relative to HIV- recipients.

RESUMEN

Chagas disease (CD), caused by Trypanosoma cruzi, is underdiagnosed in the United States. Improved screening strategies are needed, particularly for people at risk for life-threatening sequelae of CD, including people with human immunodeficiency virus (HIV, PWH). Here we report results of a CD screening strategy applied at a large HIV clinic serving an at-risk population.

RESUMEN

Coinfection of HIV and multidrug-resistant tuberculosis (MDR-TB) presents significant challenges in terms of the treatment and prognosis of tuberculosis, leading to complexities in managing the disease and impacting the overall outcome for TB patients. This study presents a remarkable case of a patient with MDR-TB and HIV coinfection who survived for over 8 years, despite poor treatment adherence and comorbidities. Whole genome sequencing (WGS) of the infecting Mycobacterium tuberculosis (Mtb) strain revealed a unique genomic deletion, spanning 18 genes, including key genes involved in hypoxia response, intracellular survival, immunodominant antigens, and dormancy. This deletion, that we have called "Del-X," potentially exerts a profound influence on the bacterial physiology and its virulence. Only few similar deletions were detected in other non-related Mtb genomes worldwide. In vivo evolution analysis identified drug resistance and metabolic adaptation mutations and their temporal dynamics during the patient's treatment course.

RESUMEN

10-Methyl-aplog-1 (10MA-1), a simplified analog of aplysiatoxin, exhibits a high binding affinity for protein kinase C (PKC) isozymes with minimal tumor-promoting and pro-inflammatory activities. A recent study suggests that 10MA-1 could reactivate latent human immunodeficiency virus (HIV) in vitro for HIV eradication strategy. However, further in vivo studies were abandoned by a dose limit caused by the minimal water solubility of 10MA-1. To overcome this problem, we synthesized a phosphate ester of 10MA-1, 18-O-phospho-10-methyl-aplog-1 (phos-10MA-1), to improve water solubility for in vivo studies. The solubility, PKC binding affinity, and biological activity of phos-10MA-1 were examined in vitro, and the biological activity was comparable with 10MA-1. The pharmacokinetic studies in vivo were also examined, which suggest that further optimization for improving metabolic stability is required in the future.

RESUMEN

Introduction: The AIDS epidemic has undergone several transformations, and, in recent years, there has been an increase in cases of HIV/AIDS among adolescents and young people. Thus, it is essential to know this population to base health actions scientifically.Objective: This study aims to analyze the epidemiological profile of adolescents living with HIV/AIDS in Espírito Santo, Brazil.Methods: A descriptive, sectional study in which notifications of HIV/AIDS among adolescents aged 13 to 19 between 2010 and 2020 were analyzed.Results: 523 adolescents with HIV/AIDS were found in the analyzed period (an average of 47 cases/year). There was a predominance of male adolescents (68.8%), older than 16 years (mean=18.0 years), of mixed race/colour (54.6%), living in the metropolitan region near the capital. It was observed that the schooling of females is lower, with 47.2% of them in elementary school, while 45.0% of the boys are in high school. In most cases, the infection occurred via sexual intercourse, among men, through homosexual relations (55.0%), and among women, through heterosexual relations (82.2%). The HIV viral load was detectable in almost all (84.8%) cases, and 11 (6.8%) of these adolescents died.Conclusion: The epidemiological profile of HIV and AIDS cases among adolescents in Espírito Santo shows a higher frequency of cases in males aged 16 to 19 years, with incomplete high school education, who acquired HIV through unprotected sex in homosexual relationships. We highlight the high percentage of young people with detectable viral loads and deaths due to complications of AIDS


Introdução: A epidemia da AIDS passou por diversas transformações e, nos últimos anos, observa-se aumento de casos de HIV/AIDS entre adolescentes e jovens. Assim, é fundamental conhecer essa população para embasar cientificamente as ações em saúde. Objetivo: analisar o perfil epidemiológico de adolescentes que vivem com HIV/AIDS no Estado do Espírito Santo, Brasil. Método: estudo descritivo, seccional, no qual foram analisadas notificações de HIV/AIDS entre adolescentes de 13 a 19 anos, entre 2010 e 2020.Resultados: foram encontrados 523 adolescentes vivendo com HIV/AIDS no período analisado (média de 47 casos/ano). Prevaleceu os adolescentes do sexo masculino (68,8%), com mais de 16 anos (média=18,0 anos), de raça/cor parda (54,6%), residentes na região metropolitana, próxima a capital. Foi observado que a escolaridade do sexo feminino é menor, estando 47,2% delas no ensino fundamental, enquanto 45,0% dos rapazes já estão no ensino médio. Em grande parte dos casos a infecção ocorreu via sexual, sendo, entre os homens, através de relações homossexuais (55,0%) e entre as mulheres por meio de relações heterossexuais (82,2%). A carga viral de HIV foi detectável em quase totalidade (84,8%) dos casos e 11 (6,8%) destes adolescentes evoluíram para óbito. Conclusão: O perfil epidemiológico dos casos de HIV e AIDS, entre os adolescentes, no Estado do Espírito Santo, demonstra maior frequência de casos no sexo masculino, na faixa etária de 16 a 19 anos, com ensino médio incompleto, que adquiriram HIV por via sexual desprotegida, em relações homossexuais. Destaca-se a alta porcentagem de jovens com carga viral detectável e os óbitos em decorrência de complicações da AIDS.

RESUMEN

We focused our attention towards the most dreadful disease that threatens the mankind of 20th century - Acquired immunodeficiency syndrome (AIDS), caused through the human immunodeficiency virus (HIV) and a sexually transmitted infection (STI). In this study, our foremost interest was to identify the potency and stability of HIV ligand- Amprenavir (APV) and its modelled functional group (Br, Cl, F, CF3, CH3, NH2) ligands through halogen and hydrogen bond contact, which will have a clear portrait on the structure activity of protein ligand interactions. This will assist chemist in synthesizing novel APV ligands, which are expected to inhibit the activity of HIV-1 protease enzyme. The binding strength of Amprenavir ligand with interacting hinge region amino acid side chains: Isoleucine (ILE 147, 150, 184), Valine (VAL 82), Alanine (ALA 28), Aspartic acid (25, 30, 125, 130) and Glycine (GLY 127, 149) were understood through interaction energy calculations at HF, B3LYP, M052X, MP2 level of theories for different basis set (6-311 G**, LANL2DZ). The present work will reveal an understandable picture about the halogen and hydrogen bond interaction that grip the contact of ligand and amino acids in the hinge region. Overall the Halogen atom (Br, Cl, F) functional groups improved the binding strength of APV in HIV protease; which provide a new novel path for the functional group preference on the ligand that enclose perfectly with the amino acid in the hinge region.Communicated by Ramaswamy H. Sarma.

RESUMEN

Management of acquired immunodeficiency syndrome (AIDS)-related diffuse large B-cell (DLBCL) and plasmablastic lymphomas (PBL) poses significant challenges. The evidence supports use of dose-adjusted EPOCH (etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin) with or without rituximab as first-line therapy. The need for central venous access, growth factors and significant toxicities limits its use in resource-constrained settings. To address these challenges, we have developed a novel regimen, CVEP (cyclophosphamide, vinblastine, etoposide, and prednisolone) based on the pharmacodynamic principles of dose-adjusted EPOCH. This single-centre phase II study evaluated the efficacy and safety of CVEP regimen in patients with de novo systemic AIDS-related DLBCL and PBL. The primary objective was complete response (CR) rates as assessed by positron emission tomography-computed tomography. The secondary objectives were incidence of Grade 3/4 toxicities, toxicities requiring hospitalisation, and disease-free survival. From May 2011 to February 2017, 42 patients were enrolled. At the end of therapy the CR rates were 69% (29/42) in the intention-to-treat population and 80.5% (29/36) in evaluable patients. At a median follow-up of 69 months, the 5-year disease-free survival was 65.3%. Out of 217 cycles administered, febrile neutropenia occurred in 19.3% and hospitalisation was required in 18.3% of cycles. There were two treatment-related deaths. The CVEP regimen is an active and safe regimen for AIDS-related DLBCL and PBL.

RESUMEN

We report a case of Talaromyces marneffei fungemia in a patient with HIV infection with a history of travelling to southern China. At first, Pneumocystis pneumonia was considered in this case because chest CT images showed typical ground-glass opacity and elevated ß-D-glucan levels. However, PCR testing of sputum for Pneumocystis jirovecii was negative and a filamentous fungus was isolated from blood cultures. The cultured fungus was subsequently identified as T. marneffei, and the patient was considered to have pneumonia caused by this organism. However, skin disease and lymphadenopathy, which are common in T. marneffei infections, were not observed during the disease course. This patient was successfully treated with voriconazole and consequently the chest CT shadow disappeared. In the present case, T. marneffei infection required differentiation from pneumonia with Pneumocystis jirovecii infection.

RESUMEN

Introducción: La coinfección del virus de inmunodeficiencia humana (VIH) y la tuberculosis ha alterado su presentación histológica, esto es particularmente frecuente en las linfadenitis. Objetivos: Realizar la caracterización etiológica de linfadenopatías producidas por el género Mycobacterium, destacar la importancia del diagnóstico precoz de esta enfermedad para evitar diseminación de la infección, tanto en pacientes inmunocompetentes como inmunodeficientes, específicamente con VIH/sida. Método: Se realizó estudio descriptivo-prospectivo entre enero de 2017 y enero de 2019. Durante este período se recibieron 5640 muestras, de estas 81 obtenidas a partir de tejido ganglionar; la toma de muestra mayoritariamente fue quirúrgica 74 (91,35 por ciento) y 7 (8,64 por ciento) por biopsia aspirativa (BAAF). Del total de muestras, 60 (74,07 por ciento) procedían de pacientes con VIH/sida, las muestras se descontaminaron por el método de ácido sulfúrico al 4 por ciento, se cultivaron en medio sólido Löwenstein-Jensen e incubaron a 37°C. Se realizaron lecturas semanalmente. Para identificar Mycobacterium tuberculosis se realizó la prueba rápida comercial inmunocromatográfica SD TB AgMPT64. Resultados: De 81 muestras analizadas se obtuvieron 22 (27,16 por ciento) aislamientos, 16 (72,72 por ciento) de Mycobacterium tuberculosis, y 6 (27,27 por ciento) de especies no tuberculosas. De estas, 18 (81,81 por ciento) procedían de pacientes con VIH/sida. Conclusión: Por todo lo antes expuesto es importante la vigilancia diagnóstica en este tipo de infección extrapulmonar, tanto para M. tuberculosis como para otras especies no tuberculosas y poder comenzar tempranamente el tratamiento específico evitando la diseminación de la infección, pues esta puede tener consecuencias fatales, sobre todo en pacientes con algún tipo de inmunosupresión, como aquellos con VHI/sida. Si un paciente mantiene fiebre prolongada, con linfadenopatías, sin síntomas respiratorios y no responde a los tratamientos con antibióticos, es necesario pensar en este tipo de infección(AU)


Introduction: The coinfection of human immunodeficiency virus (HIV) and tuberculosis has altered its histological presentation; this is particularly frequent in lymphadenitis. Objective: To carry out the etiological characterization of lymphadenopathies produced by the genus Mycobacterium, highlighting the importance of early diagnosis of this disease to avoid dissemination of the infection, both in immunocompetent and immunodeficient patients, specifically HIV / AIDS. Methods: A descriptive-prospective study was carried out between January 2017 - January 2019. During this period, 5640 samples were received, of these 81 obtained from lymph node tissue, the sample collection was mostly surgical 74 (91.35 percent) and 7 (8.64 percent) by aspiration biopsy (BAAF). Of the total samples, 60 (74.07 percent) were from HIV / AIDS patients, the samples were decontaminated by the 4 percent sulfuric acid method and cultured in solid Löwenstein-Jensen medium and incubated at 370C, the readings were made weekly. For the identification of Mycobacterium tuberculosis, the commercial SD TB AgMPT64 immunochromatographic rapid test was performed. Results: Of 81 samples analyzed, 22 (27.16 percent) isolates were obtained, 16 (72.72 percent) of Mycobacterium tuberculosis (MTB), and 6 (27.27 percent) of non-tuberculous species, of these 18 (81.81%) were from HIV / AIDS patients. Conclusion: For all the above, diagnostic surveillance is important in this type of extrapulmonary infection, both for M tuberculosis and for other non-tuberculous species and to be able to start specific treatment early, avoiding the spread of the infection, since it can have fatal consequences on all in patients with some type of immunosuppression, such as HIV/AIDS. If a patient maintains a prolonged fever, with lymphadenopathy, without respiratory symptoms and does not respond to antibiotic treatment, it is necessary to consider this type of infection(AU)

RESUMEN

Background: The incidence of Burkitt lymphoma among acquired immunodeficiency syndrome (AIDS) patients is significantly higher than that in general populations. It often features high malignancy and a poor prognosis. For patients with AIDS-related Burkitt lymphoma, the guidelines recommend the dose-adjusted EPOCH-R (DA-EPOCH-R) regimen (rituximab + etoposide vincristine + doxorubicin + cyclophosphamide + dexamethasone) as one of the first-line treatment options. If complete or partial responses are not achieved after first-line treatment, then a second-line regimen such as rituximab + gemcitabine + dexamethasone + cisplatin (R-GDP) or rituximab + ifosfamide + carboplatin + etoposide (R-ICE) can be employed instead. Patients without response to the second line regimen often have poor prognosis. However, with our growing understanding of the pathogenic mechanism of Burkitt lymphoma, it has become apparent that patients with Burkitt lymphoma who have a poor response to first- and second-line regimens require personalized treatment, such as immune checkpoint inhibitors [programmed death 1 (PD-1) inhibitors] or new small-molecule inhibitors [e.g., Bruton tyrosine kinase (BTK) inhibitors: ibrutinib and zanubrutinib; B-cell lymphoma-2 (BCL-2) inhibitors: venetoclax]. For the efficacy of the personalized treatment, the publication is scarce. Case Description: This report describes a patient with AIDS-related Burkitt lymphoma who did not achieve complete remission after first- and second-line treatment but eventually reached complete remission after combined therapy that included chemotherapy with small-molecule inhibitors, radiotherapy, and PD-1 inhibitors. During the multidisciplinary and multi-target combined therapy, patient has good tolerance. After 14 months' follow-up, patients' condition is stable. Conclusions: In addition to traditional chemotherapy and radiotherapy, the combined use of novel targeted therapies and early anti-HIV treatment maybe a choice to improve the prognosis of patients with AIDS-related refractory Burkitt lymphoma.

RESUMEN

Background: The study of acquired immunodeficiency syndrome (AIDS) related knowledge, attitude, and sex education status of Jiangsu freshmen was conducted, which can provide data support directionally for the prevention work of HIV/AIDS among this population. Methods: Male students (4,006) and female students (4,279) were selected from 20 universities or colleges in the Jiangsu province. The knowledge, attitudes, and sex education of freshmen were conducted with an online questionnaire. The log-binomial regression model was used to analyze the influencing factors of HIV/AIDS knowledge. In addition, a structural equation model was used to analyze students' health needs that affect knowledge awareness and knowledge mastery. Results: The overall awareness rate of AIDS knowledge was 87.4%. The students in undergraduate colleges (OR = 2.523, 95% CI=2.223~2.864) and independent colleges (OR = 1.389, 95%CI = 1.172~1.646) were more likely to have a higher awareness compared with the students in junior colleges. In this study, 2,011 freshmen approved of premarital behavior, 4,921 freshmen insisted on using condoms when having sex, and 8,138 freshmen were willing to take HIV antibody test when they suspected they were infected. In total, 4,703 freshmen believed that sexual health education was necessary for colleges and universities, and most of them (57.2%) hoped that sex education in schools should be improved. The direct effect of sex education on knowledge awareness and attitude is 0.15 and 0.58. The mediation effect test found that the pass ability knowledge path of sex education indirectly affected sexual attitudes (0.05). Conclusion: The awareness rate of HIV/AIDS among Jiangsu freshmen has not reached the national standard. Health education has a significant positive effect on knowledge awareness and attitude; however, students' needs in terms of time, place, and degree of sex education have not been met in time. It is necessary to strengthen the HIV/AIDS health education of college students in multiple ways.

RESUMEN

Background: human immunodeficiency virus (HIV) can disrupt the body's immune system, increasing the chance of various opportunistic infections. The risk of misdiagnosis and underdiagnosis is high for HIV and Leishmania coinfection. Visceral leishmaniasis (VL) has become a significant opportunistic infection in HIV type 1 (HIV-1)-infected patients in the epidemic region. Co-infection is difficult to diagnose, especially in non-endemic areas. Case Description: This study presents a case of VL in a middle-aged male patient with HIV coinfection, where the diagnosis was circuitous and complex. The patient was a 44-year-old male who was hospitalized due to fever. We considered common pathogen infection or hemophagocytic syndrome, so we did various etiological examinations and bone marrow biopsy smears, but no positive pathogens were found. Then we used a variety of empirical treatment, but the patient's temperature did not drop significantly. After the final diagnosis of VL using metagenomic next-generation sequencing (mNGS), we read the bone marrow smear and biopsy specimens again, and ultimately the Leishman-Donovan body and tissue intracellular pathogens were found. The patient responded well to treatment with sodium stibogluconate (SSG), his temperature gradually recovered from hyperthermia to normal, liver and spleen size gradually decreased, hemoglobin and platelet count rebounded, and weight increased by 1.5 kg after discharge from the hospital. We hope to deepen clinicians' understanding of mNGS for VL diagnosis and provide a review of the literature. Conclusions: For patients with HIV coinfection, mNGS-a test that can detect multiple pathogens simultaneously-can be used routinely when multiple pathogen tests showed no positive results, multiple empiric anti-infective therapies failed, and hospital technology and the patient's economy are adequate. While giving highly active antiretroviral therapy (HAART), liposomal amphotericin B (L-AMB) is highly recommended because of its better efficacy and lower side effects. Not only is the treatment of leishmaniasis critical but also follow-up at a later stage is essential. After discharged, the patient had no significant discomfort and no increase in body temperature, his hemoglobin and platelets increased further. He demonstrated a further reduction in liver and spleen size and a weight gain of 1.5 kg.

RESUMEN

BACKGROUND: This study aimed to explore the value of neutrophil-to-lymphocyte ratio (NLR) in combination with routine blood tests, lactate dehydrogenase (LDH), and T-lymphocyte subsets for the early diagnosis of acquired immunodeficiency syndrome (AIDS) combined with Talaromyces marneffei (TM) infection. METHODS: A total of 166 confirmed AIDS patients were enrolled in this study. The observation group included 80 AIDS patients with TM infection, and the control group consisted of 86 AIDS patients with other complications. Regression analysis was performed to evaluate the predictive value of each index and the combination of these indexes for AIDS combined with TM infection using receiver operating characteristic (ROC) curve analysis. RESULTS: NLR and LDH were significantly higher in patients in the observation group compared with those in the control group, and the differences were statistically significant (P<0.05). There was no statistical difference in platelets, infantile granulocytes (IGM), and nucleated red blood cells (NRBC) between the 2 groups (P>0.05). The area under the operating characteristic curve (AUC) of the observed indicators were: NLR, 0.628; hemoglobin (HGB), 0.704; LDH, 0.607; lymphocyte (LYM) count, 0.744; CD4+ T lymphocyte count, 0.789; and CD8+ T lymphocyte count, 0.701. The combined AUC of multiple indicators was 0.815, with a sensitivity and specificity of 76.2% and 76.1%, respectively. CONCLUSIONS: NLR, HGB, LYM, LDH, and T lymphocyte subsets were diagnostic for early AIDS combined with TM infection , and CD4+ T lymphocytes had the best diagnostic efficacy alone.

RESUMEN

RESUMEN Objetivo Determinar el conocimiento y las actitudes de un grupo de 53 jóvenes de la Cruz Roja de la Juventud en la Seccional Valle del Cauca sobre el fenómeno social del VIH/SIDA y sus portadores. Método El diseño de la investigación se basó en la línea de desarrollo humano y construcción de ciudadanía, bajo el método cuantitativo de orden descriptivo. Para la recolección de la información, se empleó un formato de encuesta de tipo descriptivo con preguntas cerradas o de alternativa fija, compuesto por un cuestionario de 39 preguntas. Resultados Entre el 69% y 72% de los jóvenes refieren conocimiento sobre sus derechos sexuales y reproductivos; sin embargo, un porcentaje bajo, entre 26% y 39%, afirma haber recibido asesoría sobre la realización de la prueba del VIH, un porcentaje menor se la ha realizado. Conclusiones Es claro el bajo nivel de reconocimiento que tienen las instituciones y los medios de comunicación como difusores de temas relacionados con la salud sexual y reproductiva y el VIH/SIDA. Por otro lado, a pesar del reconocimiento de sus derechos, perviven en los jóvenes mitos sobre la forma de contagio, la actitud de distanciamiento con los portadores y las conductas de riesgo en las prácticas sexuales.


ABSTRACT Objective Determine the knowledge and attitudes of a group of 53 young people of the Red Cross of Youth in the Valle del Cauca Sectional about the social phenomenon of HIV/AIDS and its bearers. Method The design of the research was based on the line of human development and construction of citizenship, under the quantitative method of descriptive order. For the collection of information, a descriptive survey format with closed questions or a fixed alternative was used, consisting of a questionnaire of 39 questions. Results Between 69% and 72% of young people report knowledge about their sexual and reproductive rights, however, a low percentage between 26% and 39% say they have received counseling about the HIV test and a smaller percentage have accomplished. Conclusions It is clear the low levels that institutions and media have in the dissemination of the topic of sexual and reproductive health and HIV/AIDS. Despite the recognition of their rights, myths persist about the form of contagion, the attitude of distancing with carriers and risk behaviors in sexual practices.
