HIV AIDS-Research and Palliative Care最新文献

Background: Globally, approximately 35 million people are infected with HIV infection. Sub-Saharan countries contributed 71% of global burden. Women are the most affected groups accounting for 51% of global infection and 90% of HIV infections in children (<15 years) are a result of mother to child transmission. In the absence of any intervention, mother-to-child transmission has been estimated to 30-40% that could occur at various periods like during pregnancy, delivery, and post-partum, via breastfeeding. For future generations to be born HIV-free, evidences on the level of viremia and contributing factors in pregnant mothers is important.

Objective: The objective of this study is to determine the magnitude of viral non-suppression rate among pregnant women and identify the risk factors associated with viral non-suppression.

Methods: A cross-sectional study was conducted from July 01, 2021 to June 30, 2022, in pregnant women who are on antiretroviral treatment and attending HIV viral load testing in Amhara region viral load testing sites, North West Ethiopia. Socio-demographic, clinical, and HIV-1 RNA viral load data were collected from the excel database. The data were analyzed in SPSS 23.0 statistical software.

Results: Overall viral non-suppression rate was 9.1%. In other words, the viral suppression rate was 90.9%. Pregnant women being at AIDS stages III and IV and with fair treatment adherence and suspected testers were statistically associated with increased viral non-suppression rate.

Conclusion: Relatively low viral non-suppression rate among pregnant mothers that had almost met the third 90 of UNAIDS target. But, still, some mothers received a non-suppressed viral replication specifically the odds of having a non-suppressed viral load was higher in pregnant women with poor treatment adherence and WHO Stage III and IV and suspected testers.

Background: The persistent efforts of HIV/AIDS epidemiology remain one of the world's most important community health threats. To avoid becoming an epidemic, UNAIDS has set three 90% fast-track targets for 2020, and Ethiopia has also changed its implementation since 2015. However, the achievement targets in the Amhara region have yet to be evaluated at the end of the programme period.

Objective: The aim of this study was to assess the Trends of HIV Infection and Antiretroviral Treatment outcome in Eastern Amhara Regional from 2015 to 2021, Northeast Ethiopia.

Methods: A retrospective study was conducted by reviewing the District Health Information System from 2015 to 2021. The collected data includes the trend of HIV testing services, the trend of HIV positivity, the yield of HIV testing approaches, the number of HIV positive patients linked to HIV care and treatment or access to lifelong antiretroviral therapy, viral load testing coverage, and viral suppression. A descriptive statistic and trend analysis were computed.

Results: A total of 145,639 people accessed antiretroviral therapy. The trend of HIV test positivity has been declining since 2015, peaking at 0.76% in 2015 and declining to 0.60% in 2020. A high level of positivity was reported in volunteer counselling and testing as compared with provider-initiated testing and counselling services. Following an HIV positive, there was an increase in linkage to HIV care and treatment. High suppression rates of viral load indicate testing coverage grew over time. The viral load monitoring coverage was 70% in 2021, with a viral suppression rate of 94%.

Conclusion and recommendations: The trend in achievement in the first 90s was not consistent with predefined goals (90%). On the other hand, there was good achievement in the second and third goals. Hence, intensified case-finding approaches to HIV testing should be strengthened.

Background: Although the goal of ART is to have better health, extend the life of the HIV-infected patient, and decrease HIV-related death, there is a continuation of HIV-related mortality with the use of ART. This study aimed to assess the incidence of mortality and its predictors among adult HIV/AIDS patients who were on ART follow-up at Wolaita Sodo Comprehensive specialized hospital in southern Ethiopia.

Methods: A retrospective follow-up study was conducted from May 1 to June 30, 2021 among adult HIV/AIDS patients with a total of 441 adult HIV/AIDS patients in this hospital included. Kaplan-Meier failure curve and Log rank test were fitted, and Cox-proportional hazards model was also used to identify the predictors of mortality. Both crude and adjusted hazard ratios (AHR) with their 95% confidence interval (CI) were calculated to show the strength of association. The proportional assumption was conducted by using a global test based on the Schoenfeld residuals.

Results: Incidence of the mortality rate was 5.61 (95% CI, 4.2-7.3) per 100 person-years observation. In the multivariable analysis, HIV/AIDS patients were widowed (aHR; 10.9 (95% CI, 3.13-37.99), poorly drug-adhered (aHR; 5.6 (95% CI, 2.4-13.2) and fair adhered (aHR; 3.53 (95% CI, 1.58-7.87), WHO clinical stage IV (aHR; 5.91, (95% CI, 1.41-24.71), history of substance use (aHR; 2.02 (95% CI, 1.01-4.06) and history of IV drug use (aHR; 2.26 (95% CI, 1.10-4.74) independently predicted the mortality of patients.

Conclusion: In this study, incidence of mortality was relatively high. The rate of mortality may be minimized by paying particular attention to individuals with widowing, substance use at the baseline, advanced clinical stage IV, history of IV drug use at the baseline, and those with adherence problems.

Background: HIV is a growing public health burden that threatens thousands of people in Kazakhstan. Countries around the world, including Kazakhstan, are facing significant problems in predicting HIV infection prevalence. It is crucial to understand the epidemiological trends of infectious diseases and to monitor the prevalence of HIV in a long-term perspective. Thus, in this study, we aimed to forecast the prevalence of HIV in Kazakhstan for 10 years from 2020 to 2030 by using mathematical modeling and time series analysis.

Methods: We use statistical Autoregressive Integrated Moving Average (ARIMA) models and a nonlinear epidemic Susceptible-Infected (SI) model to forecast the HIV infection prevalence rate in Kazakhstan. We estimated the parameters of the models using open data on the prevalence of HIV infection among women and men (aged 15-49 years) in Kazakhstan provided by the Kazakhstan Bureau of National Statistics. We also predict the effect of pre-exposure prophylaxis (PrEP) control measures on the prevalence rate.

Results: The ARIMA (1,2,0) model suggests that the prevalence of HIV infection in Kazakhstan will increase from 0.29 in 2021 to 0.47 by 2030. On the other hand, the SI model suggests that this parameter will increase to 0.60 by 2030 based on the same data. Both models were statistically significant by Akaike Information Criterion corrected (AICc) score and by the goodness of fit. HIV prevention under the PrEP strategy on the SI model showed a significant effect on the reduction of the HIV prevalence rate.

Conclusion: This study revealed that ARIMA (1,2,0) predicts a linear increasing trend, while SI forecasts a nonlinear increase with a higher prevalence of HIV. Therefore, it is recommended for healthcare providers and policymakers use this model to calculate the cost required for the regional allocation of healthcare resources. Moreover, this model can be used for planning effective healthcare treatments.

Background: Non-disclosure of HIV-positive status (NDHPSS) is the individual's experience of hiding their HIV status from other people or groups. People who fail to reveal their HIV-positive serostatus risk contracting the virus again, not receiving the best possible care, and even dying.

Purpose: To assess predictors of NDHPSS in people living with HIV in public health facilities in Gedeo-Zone, Southern-Ethiopia.

Methods: In Gedeo-Zone, Southern Ethiopia, a facility-based, unmatched, case-control study was carried out from the first of February to March 30, 2022GC. With a case-to-control ratio of 1:1, a total of 360 respondents (89 cases and 271 controls) were involved. The respondents were chosen using a sequential sampling technique. EpiData-V-3.1 was used to enter the data, and SPSS-V-25 was used to analyse it. To determine the factors that were connected to the result, a binary logistic regression analysis was performed. AOR at the 95% confidence interval and p-values under 0.05 were utilised to explain their statistical significance.

Results: The study had 360 participants in total-271 controls and 89 cases-resulting in a response rate of 97.6%. The average age of the participants was 35.6 years (SD: 8.3). After adjusting the possible confounders, sex (AOR = 2.8, 95% CI: 1.04-7.56), residence (AORs = 3.52, 95% CI: 2.83-9.39), WHO clinical stage I (AORs = 4.68, 95% CI: 1.9-22.1), short duration of ART follow-up care (AOR = 4.21, 95% CI: 1.65-10.73), and number of lifetime sexual partners (AOR = 6.9, 95% CI: 1.86-26.3) were significantly associated factors with the outcome.

Conclusion: According to this study, living in a rural area and being in WHO clinical stage one, in addition to being a woman and having multiple sexual partners during one's lifetime, were predictors of non-disclosure of an HIV-positive serostatus. As a result, encouraging people with HIV in WHO stage I and those who have had more than one sexual partner in their lifetime to disclose their status and expanding counselling services for rural residents and women have a substantial impact on reducing the HIV load.

Background: Maintaining good medication adherence and decreasing viral load in patients living with HIV/AIDS are critical to ensuring antiretroviral therapy's preventive and therapeutic benefits. The main objective of this study was to assess the predictors of viral load and medication adherence among HIV-positive adults under treatment at Felege Hiwot Comprehensive Specialized Hospital (FHCSH).

Methods: A retrospective cohort study design was conducted from a random sample of 281 adult HIV-infected patients under treatment at FHCSH in northwest Ethiopia from June 2017 to June 2021. Separate GLMM was used in analysis of viral load and medication adherence, and joint mode was applied to fit those two outcomes jointly. The potential correlation of those two outcomes was linked by random intercepts. Information criteria (AIC and BIC) were used for model comparison and covariance structure selection.

Results: The small standard error of significant predictors and significant correlation between viral load and medication adherence over time provide evidence for joint model selection. The correlation between viral load and medication adherence was -0.7688 (P-value=< 0.05), which indicates that the decrement of viral load tends to increase good medication adherence. Patient substance use, visit time, baseline CD4 cell, baseline hemoglobin, and the interaction of visit time by substance use were significantly associated with viral load and medication adherence jointly.

Conclusion: The study revealed that substance user adult patients, patients with low baseline CD4 cells, and patients with low baseline hemoglobin were with high viral loads and poor medication adherence. Therefore, health officials and other concerned bodies should give special attention and high intervention to patients with low baseline hemoglobin; poor adherence and low baseline CD4 cell count.

Background: Condom is one of the most commonly used and cost-effective HIV preventive measures, particularly in low-income countries. Despite the proven effect of condoms for STI/HIV prevention, there are limited data on its utilization. Hence, this community-based study aimed to assess the level and determinant factors of condom utilization among the youth of the rural Tigray.

Methods: This study was part of a large community-based cross-sectional study conducted to assess the utilization of adolescent and youth-friendly health services among randomly selected 631 youth aged 15-24 years from May 23 to June 30, 2018. We used 273 youth who reported having a history of sexual activity during the study period. The data were collected using an interviewer-administered structured questionnaire. Logistic regression analysis was used to determine the independent predictors of the outcome variable and the level of significance was declared at a P-value of <0.05.

Results: A total of 273 participants were included in the study. The mean age (+SD) of the respondents was 19.14 (±2.74) years. Only one-third (35.2%) of the respondents used a condom during their last sexual encounter and 51 (53.1%) of them used it consistently. Being married (AOR = 0.17; 95% CI: 0.04, 0.60), respondent's partner attained primary education (AOR = 0.14; 95% CI: 0.04, 0.50), and having multiple sexual partners (AOR = 6.97; 95% CI: 2.09, 23.20) were found to be the determinants of condom utilization.

Conclusion: The study participants had a low level of condom utilization. Social and sexual related factors were the major predictors of condom use among the youth. Therefore, focused interventions need to be designed specifically to strengthen condom promotion campaigns.

Introduction: We aimed to investigate whether there were changes in fundus picture and retinal microvascularity of patients with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) who were treated with highly active antiretroviral therapy (HAART).

Methods: From July 2015 to November 2016, 130 HIV/AIDS patients were collected by the Yunnan Institute of Traditional Chinese Medicine, including 63 treatment-naïve patients and 67 that received HAART for 12 months. Fundus picture lesions, retinal microvascular diameters, CD4+ T lymphocyte count and HIV-1 plasma viral loads were compared between the two groups. The recruited patients were mainly young and middle-aged, with more males than females. There were no significant differences in smoking history, comorbidities and opportunistic infections between the two groups.

Results: According to the analysis results from SPSS 20.0 software, the number of CD4+ T lymphocytes in the treated patients (563.34±2.56 cells/μL) increased significantly (P=0.009) as compared with untreated patients (451.37±2.10 cells/μL), and the HIV-1 plasma viral load reduced considerably (4794 vs 0 copy/mL, P=0.000). No significant differences were observed from the fundus picture of patients after effective HAART therapy, including the retinal artery diameter, venous diameter and arteriovenous diameter ratio.

Introduction: Engagement in the HIV care cascade is required for people living with HIV (PLWH) to achieve an undetectable viral load. However, varying definitions of engagement exist, contributing to heterogeneity in research regarding how many individuals are actively participating and benefitting from care. A standardized definition is needed to enhance comparability and pooling of data from engagement studies.

Objectives: The objective of this paper was to describe the various definitions for engagement used in HIV clinical trials.

Methods: Articles were retrieved from CASCADE, a database of 298 clinical trials conducted to improve the HIV care cascade (https://hivcarecascade.com/), curated by income level, vulnerable population, who delivered the intervention, the setting in which it was delivered, the intervention type, and the level of pragmatism of the intervention. Studies with engagement listed as an outcome were selected from this database.

Results: 13 studies were eligible, of which five did not provide an explicit definition for engagement. The remaining studies used one or more of the following: appointment adherence (n=6), laboratory testing (n=2), adherence to antiretroviral therapy (n=2), time specification (n=5), intervention adherence (n=5), and quality of interaction (n=1).

Conclusion: This paper highlights the existing diversity in definitions for engagement in the HIV care cascade and categorize these definitions into appointment adherence, laboratory testing, adherence to antiretroviral therapy, time specification, intervention adherence, and quality of interaction. We recommend consensus on how to describe and measure engagement.
