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

OBJECTIVES: The prevention of mother-to-child transmission of HIV has been a global success. But little is known about the growth parameters of infants delivered by mothers with HIV or the drug resistance of infants with HIV in China. The study aimed to assess growth parameters and drug resistance in Chinese infants exposed to HIV. METHODS: We conducted an 18-month longitudinal follow-up study of 3283 infants (3222 without HIV; 61 with HIV) born to mothers with HIV in the Guangxi Zhuang Autonomous Region between January 2015 and December 2021. The weight and length of all participants was recorded. In addition, genetic subtypes and drug resistance analysis were performed for infants with HIV. RESULTS: Compared with infants without HIV, those with HIV had significantly lower weight/length Z-scores, except at 18 months of age. The length/age Z-scores of infants with HIV was significantly reduced, except at 1 month of age. The weight/age Z-scores of infants with HIV were significantly lower at all follow-up time points. The weight/length Z-scores of male infants without HIV were significantly lower than for female infants without HIV at all follow-up time points. Male infants without HIV had lower length/age and weight/age Z-scores than female infants at the remaining follow-up points, except at 1 month of age. Of a total of 61 infants with HIV, subtype and drug-resistance data were obtained from 37 (60.66%) samples. Infants with HIV were dominated by the CRF01_AE genotype and showed a diversity of mutation sites dominated by non-nucleoside reverse transcriptase inhibitor resistance. CONCLUSION: Our study demonstrates the growth of infants exposed to HIV in southwest China and provides detailed information on subtype distribution and drug resistance of those with HIV. Nutritional support and drug-resistance surveillance for infants exposed to HIV need to be strengthened.

RESUMO

OBJECTIVE: We described mortality and loss to follow-up (LTFU) in children and adolescents who were under care for more than 5 years following initiation of antiretroviral therapy (ART). METHODS: Patients were followed from 5 years after ART until the earlier of their 25th birthday, last visit, death, or LTFU. We used Cox regression to assess predictors of mortality and competing risk regression to assess factors associated with LTFU. RESULTS: In total, 4488 children and adolescents initiating ART between 1997 and 2016 were included in the analysis, with a median follow-up time of 5.2 years. Of these, 107 (2.2%) died and 271 (6.0%) were LTFU. Mortality rate was 4.35 and LTFU rate 11.01 per 1000 person-years. Increased mortality was associated with AIDS diagnosis (adjusted hazard ratio [aHR] 1.71; 95% confidence interval [CI] 1.24-2.37), current CD4 count <350 cells/mm3 compared with ≥500 (highest aHR 13.85; 95% CI 6.91-27.76 for CD4 <200), viral load ≥10 000 copies/mL compared with <400 (aHR 3.28; 95% CI 1.90-5.63), and exposure to more than one ART regimen (aHR 1.51; 95% CI 1.14-2.00). Factors associated with LTFU were male sex (adjusted subdistribution hazard ratio [asHR] 1.29; 95% CI 1.04-1.59), current viral load >1000 copies/mL compared with <400 (highest asHR 2.36; 95% CI 1.19-4.70 for viral load 1000-9999), and ART start after year 2005 compared with ≤2005 (highest asHR 5.96; 95% CI 1.98-17.91 for 2010-2016). CONCLUSION: For children and adolescents surviving 5 years on ART, both current CD4 and viral load remained strong indicators that help to keep track of their treatment outcomes. More effort should be made to monitor patients who switch treatments.

RESUMO

Talaromyces marneffei (T. marneffei) stands out as the sole thermobiphasic fungus pathogenic to mammals, including humans, within the fungal community encompassing Ascomycota, Eurotium, Eurotiumles, Fungiaceae, and Cyanobacteria. Thriving as a saprophytic fungus in its natural habitat, it transitions into a pathogenic yeast phase at the mammalian physiological temperature of 37°C. Historically, talaromycosis has been predominantly associated with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), classified among the three primary opportunistic infections linked with AIDS, alongside tuberculosis and cryptococcosis. As advancements are made in HIV/AIDS treatment and control measures, the incidence of talaromycosis co-infection with HIV is declining annually, whereas the population of non-HIV-infected talaromycosis patients is steadily increasing. These patients exhibit diverse risk factors such as various types of immunodeficiency, malignant tumors, autoimmune diseases, and organ transplantation, among others. Yet, a limited number of retrospective studies have centered on the clinical characteristics and risk factors of HIV-negative talaromycosis patients, especially in children and patients with hematological malignancies, resulting in an inadequate understanding of this patient cohort. Consequently, we conducted a comprehensive review encompassing the epidemiology, pathogenesis, risk factors, clinical manifestations, diagnosis, treatment, and prognosis of HIV-negative talaromycosis patients, concluding with a prospectus of the disease's frontier research direction. The aim is to enhance comprehension, leading to advancements in the diagnosis and treatment rates for these patients, ultimately improving their prognosis.

RESUMO

BACKGROUND: People with HIV/AIDS (PWHA) have 7-36 times greater risk for completed suicide associated with depression symptoms compared to general population. However, no study has sufficiently analyzed the mediating or moderating variables of the relationship between depression and suicidal ideation in Rwanda. OBJECTIVES: This study aimed to examine how complicated grief mediates and substance abuse moderates the effects of depression symptoms on suicidal ideation. METHODS: Data were collected from a convenient sample of 140 participants (M-age = 38.79 years, SD = 10.218) receiving antiretroviral therapy (ART) at Remera Health Center in a cross-sectional study. Multiple linear regression and Sobel test were used to examine the relationships between depression symptoms, complicated grief, suicidal ideation, and substance abuse. RESULTS: The results indicated that 29% of the sample had clinically significant symptoms of depression and 18% had suicidal ideation. The interaction between substance abuse and depression symptoms (ß = .468, t = 8.02, p = 0.000) was a significant predictor, explaining the 55.7% of variance in suicidal ideation. Furthermore, the Sobel test demonstrated that complicated grief mediated the effects of depression symptoms (t = 4.67, SE = 0.0101, p ≤ 0.001) on suicidal ideation. CONCLUSION: The results suggest that depression symptoms are associated with an increased risk of suicidal ideation, and this risk significantly amplified in the presence of complicated grief and substance abuse. These findings highlight the importance of integrating mental health services, particularly those addressing depression, complicated grief, and substance abuse, into HIV care programs to mitigate the risk of suicidal ideation among PWHA.

RESUMO

BACKGROUND: Metabolic syndrome (MetS) elevates the risk of heart disease and stroke. In recent decades, the escalating prevalence of MetS among people living with HIV/AIDS (PLWHA) has garnered global attention. Despite MetS development being associated with both traditional and HIV-related factors, evidence from prior studies has shown variability across geographical regions. This study aimed to conduct a systematic review and meta-analysis of MetS burdens in adult PLWHA at the regional and global levels, focusing on the common effect size of HIV infection and antiretroviral therapy (ART) on MetS. METHODS: This review followed the PRISMA 2020 guidelines. A comprehensive search and review of original articles related to MetS and HIV published in peer-reviewed journals between January 2000 and December 2023 were conducted. A random effects model was used to calculate the pooled prevalence/incidence of MetS and the common effect size of HIV infection and ART exposure on MetS. RESULTS: A total of 102 studies from five continents comprising 78,700 HIV-infected participants were included. The overall pooled prevalence of MetS was 25.3%, 25.6% for PLWHA on ART, and 18.5% for those not receiving treatment. The pooled incidence of MetS, calculated from five studies, was 9.19 per 100 person-years. The highest pooled prevalence of MetS was observed in the Americas (30.4%), followed by the Southeast Asia/Western Pacific regions (26.7%). HIV-infected individuals had 1.6 times greater odds of having MetS than non-HIV-infected individuals did (pooled OR = 1.604; 95% CI 1.154-2.230), and ART exposure had 1.5 times greater odds of having MetS than nontreatment had (pooled OR = 1.504; 95% CI 1.217-1.859). CONCLUSIONS: HIV infection and ART exposure contribute significantly to the increased burden of MetS. Regions with a high burden of HIV and MetS should prioritize awareness and integrated care plans for major noncommunicable diseases (NCDs), such as heart disease and stroke. The implementation of integrated care for HIV/AIDS patients and NCDs is essential for addressing the high burden of multimorbidity in PLWHA. REGISTRATION NUMBER: INPLASY202290018.

RESUMO

Marriage of convenience is a unique phenomenon in China where a gay man and a lesbian get married to fulfill social expectations while retaining their homosexual identities. Men who have sex with men (MSM) are at increased risk of HIV infection and intimate partner violence (IPV) following HIV disclosure. A sample of 232 HIV-infected MSM in the marriage of convenience was recruited online and completed questionnaires about experiences of IPV, HIV disclosure, and their sociodemographic, clinical, and psychosocial characteristics. Our results showed that over half (57.3%) of HIV-infected MSM had disclosed their HIV status to their lesbian spouses. Bisexual men, having children with their lesbian spouse, HIV diagnosis time >24 months, having a current fixed gay partner, having disclosed HIV to their current fixed gay partners, higher levels of social support, lower levels of self-stigma related to HIV infection, no depression, and no suicidal ideation were all independently associated with an increased likelihood of disclosing to lesbian spouses. Approximately 61.6% of participants experienced at least one type of IPV from either a gay partner, a lesbian spouse, or both in the past 12 months. HIV disclosure to lesbian spouses was associated with an increased risk of IPV. Our findings reveal the high prevalence of IPV among HIV-infected MSM in the marriage of convenience and its association with HIV disclosure, which warrants policy, clinical, and research efforts to design targeted and comprehensive interventions to improve HIV disclosure while preventing IPV among this population.

RESUMO

Evidence suggests adverse health effects from vaporized nicotine (VN) use, such as electronic "e" cigarettes, and limited efficacy to aid tobacco cessation. People with HIV (PWH) smoke tobacco at higher rates than the general population, with greater morbidity, highlighting the necessity of effective tobacco cessation tools. PWH may be more vulnerable to adverse effects of VN. Using semi-structured 1:1 interviews, we examined health beliefs regarding VN, patterns of use, and perceived effectiveness for tobacco cessation among PWH in HIV care at three geographically diverse U.S. sites. PWH (n = 24) had limited understanding of VN product content or health effects, presuming VN less harmful than tobacco cigarettes (TC). VN failed to adequately replicate the psychoactive effects or desired ritual of smoking TC. Concurrent TC use, and continuous VN use throughout the day, was common. Satiety using VN was elusive, and consumption quantity was difficult to track. VN had limited desirability and durability as a TC cessation tool among the interviewed PWH.

RESUMO

Psychosocial support (PSS) to caregivers of HIV-infected infants on antiretroviral treatment (ART) is crucial to ensure ART adherence and sustained long-term viral suppression in children. A specific approach including tools to monitor and understand adherence behavior and risk factors that prevent optimal treatment compliance are urgently needed. This qualitative exploratory study, conducted in southern Mozambique, monitored the infants' viral response trajectories during 18 months follow-up, as a measure of adherence, reviewed the caregiver's PSS session notes and the answers to a study questionnaire, to analyze whether the standard PSS checklist applied to infants' caregivers can identify barriers influencing their adherence. Only 9 of 31 infants had sustained virologic response. Reported factors affecting adherence were: difficulties in drugs administration, shared responsibility to administer treatment; disclosure of child's HIV status to family members but lack of engagement; mother's ART interruption and poor viral response. In conclusion, we found that the standard PSS approach alone, applied to caregivers, was lacking focus on many relevant matters that were identified by the study questionnaire. A comprehensive patient-centered PSS package of care, including an adherence risk factor monitoring tool, tailored to caregivers and their children must be developed.

RESUMO

BACKGROUND: Despite substantial antiretroviral therapy (ART) coverage among individuals with human immunodeficiency virus (HIV) infection in Tanzania, viral load suppression (VLS) among HIV-positive children receiving ART remains intolerably low. This study was conducted to determine factors affecting the nonsuppression of VL in children with HIV receiving ART in the Simiyu region; thus, an effective, sustainable intervention to address VL nonsuppression can be developed in the future. METHODS: We conducted a cross-sectional study including children with HIV aged 2-14 years who were currently presenting to care and treatment clinics in the Simiyu region. We collected data from the children/caregivers and care and treatment center databases. We used Stata™ to perform data analysis. We used statistics, including means, standard deviations, medians, interquartile ranges (IQRs), frequencies, and percentages, to describe the data. We performed forward stepwise logistic regression, where the significance level for removal was 0.10 and that for entry was 0.05. The median age of the patients at ART initiation was 2.0 years (IQR, 1.0-5.0 years), and the mean age at HIV VL (HVL) nonsuppression was 8.8 ± 2.99 years. Of the 253 patients, 56% were female, and the mean ART duration was 64 ± 33.07 months. In multivariable analysis, independent predictors of HVL nonsuppression were older age at ART initiation (adjusted odds ratio [AOR] = 1.21; 95% confidence interval [CI] 1.012-1.443) and poor medication adherence (AOR, 0.06; 95% CI 0.004-0.867). CONCLUSIONS: This study showed that older age at ART initiation and poor medication adherence play significant roles in HVL nonsuppression. HIV/AIDS programs should have intensive interventions targeting early identification, ART initiation, and adherence intensification.

RESUMO

BACKGROUND: Interruption in Treatment (IIT) is a challenge in HIV care and treatment programs in sub- Saharan Africa. High IIT among HIV adolescents has both individual and potential public health consequences including discontinuation of treatment, increased HIV transmission and risk of death. In this era of test and treat policy it is important to ensure that patients remain connected to HIV clinics to enable achieve UNAIDS 95-95-95 targets timely. This study aimed to assess risk factors for IIT among HIV-positive adolescence in Tanzania. METHODS: We conducted retrospective longitudinal cohort study using secondary data of adolescent patients enrolled in care and treatment clinics in Tanga from October 2018 to December 2020. We defined Interuption in Treatment as missing clinic visits for 90 consecutive days after the last scheduled appointment date on anti-retroviral therapy (ART). Cox proportional hazard regression models were employed to identify risk factors of the outcome variable. RESULTS: Among 2,084 adolescents of age between 15 and 19 years were followed for two years, whereby 546 (26.2%) had interrupted treatment. The median age of the participants was 14.6 years (interquartile range, IQR: 12.6-16.6 years), with age between 15 and 19 years, male sex, with advanced HIV disease and were not on Dolutegravir (DTG) related regimens were associated with interruption in treatment; (Hazard ratio (HR) 1.43, 95% CI: 1.23-1.66, p < 0.0001, HR 2.47, 95% CI: 1.62-3.77, p < 0.0001, HR: 2.47, 95% CI: 1.91- 3.21, p < 0.0001 and HR: 6.67, 95% CI: 3.36- 7.04, p < 0.0001 respectively). Adolescents who were on ART for less or equal one year compared to those on ART for more than one year were protective toward interruption in treatment (HR: 0.68, 95% CI: 0.54-0.87, p = 0.002). CONCLUSIONS: The risk of interruption in treatment was high among adolescents in HIV care and treatment facilities in Tanga. This might lead to poor clinical outcomes, and increased drug resistance among ART-initiated adolescents. Placing more adolescents with DTG based drug, strengthening access to care and treatment and rapid tracking of patients is recommended to improve patient outcomes.

RESUMO

BACKGROUND: Intimate Partner Violence (IPV) is prevalent among HIV-infected men who have sex with men (MSM), with well-established risk factors and adverse outcomes. However, there is a lack of comprehensive investigation of both upstream risk factors and downstream adverse outcomes among HIV-infected MSM in a Chinese context. This study aimed to examine IPV and its associations among a Chinese sample of HIV-infected MSM. METHODS: A cross-sectional study was conducted among 294 HIV-infected MSM in Jinan City from June to December 2020. All data were collected through an online questionnaire, which included IPV, sexual risk behavior, antiretroviral therapy (ART) adherence, depression, anxiety, and suicidal ideation. Chi-square tests and multivariate logistic regressions were performed to examine risk factors and adverse outcomes of IPV. RESULTS: Of the 294 HIV-infected MSM, 71.1% experienced any IPV, including control (37.1%), threat of public identity (30.6%), emotional violence (25.2%), security threat (18.4%), and physical violence (13.9%). The prevalence of sexual risk behavior, good ART adherence, depression, anxiety, and suicidal ideation was 55.1%, 53.4%, 48.3%, 32.3%, and 65.0%, respectively. Abuse of methamphetamine (METH) (aOR:2.79; 95%CI:1.43 ~ 5.45), capsule 0 or stimulating liquid (aOR:2.68; 95%CI:1.31 ~ 5.47), Magu (aOR:3.16; 95%CI:1.51 ~ 6.60), and other new drugs (aOR:2.87; 95%CI:1.52 ~ 5.43), disclosing HIV infection to partners (aOR:2.03; 95%CI:1.10 ~ 3.78), and gay sexual orientation (aOR = 3.32; 95%CI: 1.82 ~ 6.05) were significantly correlated with the experience of IPV. In addition, IPV was significantly associated with sexual risk behavior (aOR = 2.02; 95%CI:1.16 ~ 3.53), ART adherence (aOR = 2.63; 95%CI:1.46 ~ 4.74), depression (aOR = 3.83; 95%CI:2.09 ~ 7.02), anxiety (aOR = 2.27; 95%CI:1.19 ~ 4.35), and suicidal ideation (aOR = 3.78; 95%CI:2.11 ~ 6.80). CONCLUSIONS: IPV is prevalent among HIV-infected MSM and is associated with poor behavioral and mental health, highlighting more efforts are needed to address this issue. The finding that new drug abuse, HIV disclosure, and gay sexual orientation are associated with increased risk of IPV provides essential insights for the development of comprehensive and targeted IPV prevention and intervention programs in the future.

RESUMO

We studied the relative length of telomeres in newborns with unrealized perinatal transmission of HIV (zero viral load according to PCR results). A cross-sectional survey of 62 newborns of HIV-infected mothers (Apgar score 8); the control group consisted of 80 healthy newborns (Apgar score 8). DNA extracted from whole venous blood samples was analyzed. In newborns of HIV-infected mothers, the relative length of telomeres was significantly lower (0.69 (0.66; 0.72)) than in newborns of the control group (1.1 (0.97; 1.22)) (p<0.001). No significant differences in the relative length of telomeres were found between newborns of mothers with a viral load at the time of delivery and with undetectable viral load: 0.69 (0.66; 0.73) and 0.69 (0.63; 0.72). These findings indicate that HIV-infection in mothers or exposure to antiretroviral therapy has an impact on the relative telomere length in leukocytes of newborns.

RESUMO

BACKGROUND: Immunization of vulnerable populations with distinct immunity often results in suboptimal immunogenicity, durability, and efficacy. METHODS: Safety and immunogenicity profiles of BNT162b2 messenger RNA coronavirus disease 2019 (COVID-19) vaccine, among people living with human immunodeficiency virus (HIV), were evaluated in 28 perinatally HIV-infected patients under antiretroviral therapy (ART) and 65 healthy controls (HCs) with no previous history of COVID-19. Thus, we measured severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific humoral and CD4+ T cell responses. Samples were collected before vaccination (baseline, day [D] 0), at the second dose (D21), and at 4 weeks (D28) and 6 months (D180) after D0. Proteomic profiles at D0 and D28 were assessed with a multiplexed proximity extension assay (Olink) on plasma samples. RESULTS: All HIV-infected patients mounted similar anti-SARS-CoV-2 humoral responses to those of HCs, albeit with lower titers of anti-trimeric S at D28 (P = .01). Only peripheral blood mononuclear cells of HIV-infected patients demonstrated at D28 an impaired ability to expand their specific (CD40L+) CD4+ T-cell populations. Similar humoral titers were maintained between the 2 groups at 6-months follow-up. We additionally correlated baseline protein levels to either humoral or cellular responses, identifying clusters of molecules involved in immune response regulation with inverse profiles between the 2 study groups. CONCLUSIONS: Responses of ART-treated HIV-infected patients, compared to those of HCs, were characterized by distinct features especially within the proteomic compartment, supporting their eligibility to an additional dose, similarly to the HC schedule.

RESUMO

The purpose of this study was to assess the prevalence of chlamydia or gonorrhea and factors associated with the diagnoses among people with HIV (PHIV) in the Ryan White Program Part A (RWP) in Miami-Dade County, Florida. We used 2017 calendar year data to identify factors associated with a chlamydia or gonorrhea diagnoses using logistic regression. About 50% of the 7110 PHIV who were ≥18 years old in active Ryan White care in 2017 reported being screened for chlamydia or gonorrhea. Of those screened, 2.3% reported diagnoses of chlamydia, gonorrhea or both. In the adjusted model, compared to PHIV ≥40 years-old, PHIV aged 18-24 and 25-39 years reported higher odds of diagnoses (adjusted odds ratio [aOR] 4.29; 95% confidence interval [CI]: 1.73-10.63 and aOR 4.58; 95% CI; 2.62-7.99 respectively). Those with multiple sexual partners in the last 12 months reported higher odds of diagnoses (aOR 1.67; (95% CI; 1.04-2.69)). Screening rates for chlamydia or gonorrhea are low, relative to CDC guidelines. Interventions are needed to increase rates of screening and targeted behavioral risk reduction techniques are highly recommended among those 18-39 years of age and those who have multiple sexual partners.

RESUMO

This study aimed to examine intimate partner violence (IPV) as it relates to both partners' perceptions of IPV and sexual behaviors, considering how their IPV might be interdependent within the relationship dynamics. The sample consisted of 713 female-male dyads in which women were pregnant and living with HIV in rural South Africa. Using an actor-partner interdependence model (APIM), we examined the interdependent influence of psychological and physical IPV on men by their female partners and psychological and physical IPV on women by their male partners on sexual risk behavior. The APIM model found there were no actor (b = -0.06, SE = 0.05, p = .221) or partner (b = -1.2, SE = 0.06, p = .056) effects contributing to protected sex by female IPV victimization. In contrast, significant actor (b = -0.28, SE = 0.06, p < .001) and partner (b = -0.29, SE = 0.06, p < .001) effects for protection were related to male IPV victimization. The model also found that the covariate of female HIV disclosure was associated with both male (b = 0.5, SE = 0.12, p < .001) and female protected sexual intercourse (b = 0.58, SE = 0.1, p < .001). Female HIV disclosure was related to an increased likelihood of protected sex by both male and female partners. As male partners reported more IPV victimization, the likelihood of protected sex between male and female partners decreased.Trial registration: ClinicalTrials.gov identifier: NCT02085356.

RESUMO

OBJECTIVES: Despite sustained viral suppression with effective antiretroviral therapy (ART), HIV-infected patients with suboptimal immune recovery are still at high risk of both non-AIDS-related and AIDS-related events. The aim of this study was to investigate determinants potentially associated with suboptimal CD4 + T cell count recovery during free ART with sustained viral suppression among an HIV-infected Yi ethnicity population in Liangshan Prefecture, an area in China with high HIV prevalence. METHODS: This retrospective study included HIV-infected Yi adults (≥ 18 years and baseline CD4 + T cell count less than 500 cells/µL) for whom ART supported by National Free Antiretroviral Treatment Program was initiated between January 2015 and December 2018 in Zhaojue County, Liangshan Prefecture. Virological suppression (viral load < 50 copies/mL) was achieved within 12 months after ART initiation, and sustained virological suppression was maintained. Multivariate log-binomial regression analysis was used to assess determinants of suboptimal immune recovery. RESULTS: There were 140 female and 137 male patients in this study, with a mean age of 36.57 ± 7.63 years. Most of the Yi patients were infected through IDU (48.7%) or heterosexual contact (49.8%), and the anti-HCV antibody prevalence was high (43.7%, 121/277). Of the 277 patients with a mean ART duration of 3.77 ± 1.21 years, complete immune recovery occurred in only 32.9%. The baseline CD4 + T cell count in patients with suboptimal and intermediate immune recovery was 248.64 ± 108.10 and 288.59 ± 108.86 cells/µL, respectively, which was much lower than the baseline 320.02 ± 123.65 cells/µL in patients who achieved complete immune recovery (p < 0.001). Multivariable analysis demonstrated that low pre-ART CD4 + cell count and coinfection with HCV were associated with immune recovery of the HIV patients. CONCLUSIONS: Our study suggests that for HIV-infected Yi patients in Liangshan Prefecture, prompt ART initiation after diagnosis of HIV infection should be applied, and curative HCV treatment should be given to patients with HCV/HIV coinfection to improve the immunological effectiveness of ART. Trial registration None.

RESUMO

INTRODUCTION: Ghana recorded 19,931 new annual HIV infections in 2018 translating to 14,181 AIDS-related deaths. Mass media is capable of ensuring the sustainability of initiatives aimed at curbing HIV/AIDS epidemic by reducing HIV/AIDS stigma and discrimination. The study aimed at exploring if mass media plays a role in whether HIV-infected female teachers should be allowed to teach in Ghana. MATERIALS AND METHODS: The study used women's file of the 2014 Ghana Demographic and Health Survey (GDHS). The current study was restricted to 6025 women who had complete information on the variables analysed. Binary Logistic regression was conducted between mass media and the dependent variable whilst controlling for the effect of the significant covariates. The results were presented in odds ratio (OR) and adjusted odds ratio (AOR) at 95% confidence interval (CI). All analyses were carried out using STATA version 14.0. RESULTS: Generally, 51% of the women mentioned that HIV-infected female teachers should be allowed to teach in Ghana. Women who accessed mass media had higher odds of endorsing that HIV-infected female teachersshould be allowed to teach compared to those without access to mass media [AOR = 1.37, CI 1.200-1.555], just as among those  with secondary or higher education compared to those with no formal education [AOR = 1.30, CI 1.102-1.529]. Rural inhabitants had decreased odds of proclaiming that HIV-infected female teachers should be allowed to continue teaching compared with urban residents [AOR = 0.83, CI 0.717-0.957]. CONCLUSIONS: Endorsement of HIV-positive female teachers' continued teaching was associated with access to mass media. This is suggestive that various mass media platforms could help to reach the public with HIV/AIDS-related information, particularly those that touch on stigma and discrimination, which will potentially increase women's knowledge and shape their perceptions about persons living with HIV.

RESUMO

BACKGROUND: Provider Initiated Testing and Counseling (PITC) among hospitalized children have shown to increase the probability of identifying HIV-infected children and hence be able to link them to HIV care. We aimed at determining the prevalence, clinical characteristics and outcome of HIV-infected children admitted at Bugando Medical Centre (BMC) after active provision of PITC services. METHODS: A cross-sectional study with follow up at three months post enrollment was done. Children with unknown HIV status were tested for HIV infection as per 2012 Tanzanian algorithm. Questionnaires were used to collect demographic, clinical and follow up information. Data was statistically analyzed in STATA v13. RESULTS: A total of 525 children were enrolled in the study. Median [IQR] age was 28 [15-54] months. Males consisted of 60.2% of all the participants. HIV prevalence was 9.3% (49/525). Thirty-three (67.3%) of HIV-infected children were newly diagnosed at enrolment. Thirty-nine (79.6%) of all HIV-infected patients had WHO HIV/AIDS clinical stage four disease, 10 (20.4%) had WHO clinical stage three and none qualified in stage one or two. About 84% (41/49) of HIV infected children had severe immunodeficiency at the time of the study. Factors that were independently associated with HIV infection were, cough (OR 2.40 [1.08-5.31], p = 0.031), oral thrush (OR 20.06[8.29-48.52], p < 0.001), generalized lymphadenopathy (OR 5.61 [1.06-29.56], p = 0.042), severe acute malnutrition (OR 6.78 [2.28-20.12], p = 0.001), severe stunting (OR 9.09[2.80-29.53], p = 0.034) and death of one or both parents (OR 3.62 [1.10-11.87], p = 0.034). The overall mortality (in-hospital and post-hospital) was 38.8% among HIV-infected children compared with 14.0% in HIV-uninfected children. Within three months period after discharge from the hospital, 71.4% (25/35) of discharged HIV-infected children reported to have attended HIV clinic at least once and 60.0% (21/35) were on antiretroviral medications. CONCLUSION: PITC to all admitted children identified significant number of HIV-infected children. Mortality among HIV-infected children is high compared to HIV-uninfected. At the time of follow up about 30% of discharged HIV-infected children did not attend to any HIV care and treatment clinics. Therefore effective efforts are needed to guarantee early diagnosis and linkage to HIV care so as to reduce morbidity and mortality among these children.

RESUMO

Human milk provides neonates with various components that ensure newborns' growth, including protection from bacterial and viral infections. In neonates, the biological functions of many breast milk components can be very different compared with their functions in the body fluids of healthy adults. Catalytic antibodies-abzymes hydrolyzing peptides, proteins, DNAs, RNAs, and oligosaccharides were detected not only in the blood sera of autoimmune patients but also in human milk. Non-coding microRNAs (18-25 nucleotides) are intra- and extra-cellular molecules of different human fluids. MiRNAs possess many different biological functions, including regulating several hundred genes. Five of them: miR-148a-3p, miR-200c-3p, miR-378a-3p, miR-146b-5p and let-7f-5p were previously found in milk in increased concentrations. Here, we determined number of copies of these miRNAs in 1 mg of analyzed cells, lipid fractions, and plasmas of human milk samples. The relative amount of microRNA decreases in the following order: cells ¼ lipid fraction > plasma. IgGs and sIgAs were isolated from milk plasma, and their activity in the hydrolysis of five microRNAs was compared. In general, sIgAs demonstrated higher miRNA-hydrolyzing activity than IgGs antibodies. The hydrolysis of five microRNAs by sIgAs and IgGs was site-specific. The relative activity of each microRNA hydrolysis was very dependent on the milk preparation. The correlation coefficients between the content of five RNAs in milk plasma and the relative activity of sIgAs than IgGs in their hydrolysis strongly depended on individual microRNA and changed from -0.01 to 0.80. Thus, it was shown that milk contains specific antibodies-abzymes hydrolyzing microRNAs specific for human milk.
