Effect of late HIV diagnosis on HIV-related mortality among adults in general hospitals of Central Zone Tigray, northern Ethiopia: a retrospective cohort study

Highly active antiretroviral therapy is necessary but not sufficient. A systematic review and meta-analysis of mortality incidence rates and predictors among HIV-infected adults receiving treatment in Ethiopia, a surrogate study for resource-poor settings

BACKGROUND

Owing to the introduction of highly active antiretroviral therapy (HAART), the trajectory of mortality and morbidity associated with human immunodeficiency virus (HIV) infection has significantly decreased in developed countries. However, this remains a formidable public health challenge for people living with HIV in resource-poor settings. This study was undertaken to determine the pooled person-time incidence rate of mortality, analyze the trend, and identify predictors of survival among HIV-infected adults receiving HAART.

METHODS

Quantitative studies were searched in PubMed, Embase, Scopus, Google Scholar, African Journals Online, and Web of Science. The Joana Briggs Institute critical appraisal tool was used to assess the quality of the included articles. The data were analyzed using the random-effects Dersimonian-Laird model.

RESULTS

Data abstracted from 35 articles involving 39,988 subjects were analyzed. The pooled person-time incidence rate of mortality (all-cause) was 4.25 ([95% uncertainty interval (UI), 3.65 to 4.85]) per 100 person-years of observations. Predictors of mortality were patients aged ≥ 45 years (hazard ratio (HR), 1.70 [95% UI,1.10 to 2.63]), being female (HR, 0.82 [95% UI, 0.70 to 0.96]), history of substance use (HR, 3.10 [95% UI, 1.31 to 7.32]), HIV positive status non disclosure (HR, 3.10 [95% UI,1.31 to 7.32]), cluster of differentiation 4 + T cell - count < 200 cells/mm3 (HR, 3.23 [95% UI, [2.29 to 4.75]), anemia (HR, 2.63 [95% UI, 1.32 to 5.22]), World Health Organisation classified HIV clinical stages III and IV (HR, 3.02 [95% UI, 2.29 to 3.99]), undernutrition (HR, 2.24 [95% UI, 1.61 to 3.12]), opportunistic infections (HR, 1.89 [95% UI, 1.23 to 2.91]), tuberculosis coinfection (HR, 3.34 [95% UI, 2.33 to 4.81]),bedridden or ambulatory (HR,3.30 [95% UI, 2.29 to 4.75]), poor treatment adherence (HR, 3.37 [95% UI,1.83 to 6.22]), and antiretroviral drug toxicity (HR, 2.60 [95% UI, 1.82 to 3.71]).

CONCLUSION

Despite the early introduction of HAART in Ethiopia, since 2003, the mortality rate has remained high. Therefore, guideline-directed intervention of identified risk factors should be in place to improve overall prognosis and increase quality-adjusted life years.

The effect of late presentation on HIV related mortality among adolescents in public hospitals of north showa zone Oromiya, Ethiopia; 2022: a retrospective cohort study

BACKGROUND

Late human immunodeficiency virus (HIV) diagnosis is the most prominent cause of HIV/AIDS-related mortality and also increases the risk of transmission and spread of the disease in society. Adolescents are the most vulnerable population's age group for HIV infection in several settings, but expanding access to early HIV testing remains a challenge. Consequently, a significant proportion of adolescents are still dying of HIV-related causes, and the current study aimed at assessing the effect of late presentation on HIV-related mortality among adolescents living with HIV.

METHODS

An institutional-based retrospective cohort study was conducted from August 21-November 21, 2022, at selected public hospitals in the North Showa Zone of Oromiya, Ethiopia. All adolescents living with HIV who had received no ART and presented for ART follow-up at public hospitals from September 1, 2012, to August 31, 2021, were included in the study. Data entry was done by Epi-data version 3.1.1 software and exported to Stata version 16 for further analysis. Both bi-variable and multivariable analyses were performed using the Cox proportional hazard model to compare the HIV-related mortality of early and late-presented adolescents using an adjusted hazard ratio at a 95% confidence interval (CI).

RESULTS

A total of 341 medical records of adolescents were included in the study, contributing an overall incidence rate of 3.15 (95% CI: 2.21-4.26) deaths per 100 person-years of observation throughout the total follow-up period of 1173.98 person-years. Adolescents with late presentation for HIV care had three times the higher hazard of mortality (adjusted hazard ratio (aHR) = 3.00; 95% CI: 1.22-7.37) as compared to those with early presentation for HIV/AIDS care. Adolescents within the age range of 15-19 years old (aHR = 3.56; 95% CI: 1.44-8.77), rural residence (aHR = 2.81; 95% CI: 1.39-5.68), poor adherence to ART (aHR = 3.17; 95% CI: 1.49-6.76), and being anemic (aHR = 3.09; 95% CI: 1.52-6.29) were other independent predictors of HIV-related mortality.

CONCLUSION

The study found a substantial link between HIV late presentation to care and mortality among adolescents. Residence, age, antiretroviral therapy (ART) medication adherence, and anemia status were also found to be other independent predictors of HIV-related mortality. To achieve the ultimate aim of lowering mortality among adolescents living with HIV, rigorous emphasis must be placed on early presentation for HIV/AIDS care. In addition, counseling on adherence and prompt diagnosis and treatment of anemia are highly recommended to reduce mortality.

Sociodemographic correlates of late HIV diagnosis among men who have sex with men (MSM) in Ghana

Timely HIV diagnosis and medical engagement are crucial for effective viral load suppression and treatment as prevention. However, significant delays persist, particularly in Africa, including Ghana. This study focused on Ghanaian men whose route of exposure to HIV was through same-gender sexual contact (MSM), a group disproportionately impacted by HIV. Using structured surveys, we investigated the sociodemographic factors associated with late HIV diagnosis, a topic with limited existing research. Results indicate that older age groups were associated with an increased risk of late diagnosis compared to the 18-24 age group. Among the demographic variables studied, only age showed a consistent association with late HIV diagnosis. This study underscores the importance of targeted interventions to address HIV diagnosis disparities among MSM in Ghana, particularly for older age groups. The findings emphasize the need for tailored interventions addressing age-related disparities in timely diagnosis and engagement with medical services among this population. Such interventions can play a crucial role in reducing the burden of HIV within this community and fostering improved public health outcomes.

Late presentations and missed opportunities among newly diagnosed HIV patients presenting to a specialty clinic in Lebanon

Late presentation to medical care of individuals infected with the human immunodeficiency virus (HIV) is linked to poor outcomes and increased morbidity and mortality. Missed opportunities for a prompt diagnosis are frequently reported among late presenters. We aimed to estimate the proportion of late presenters and missed opportunities in diagnosis among newly diagnosed HIV-positive subjects presenting to a specialty clinic in Lebanon. This is a retrospective chart review of all newly diagnosed adult HIV-positive subjects presenting to clinic from 2012 to 2022. Demographic, laboratory, and clinical data were collected at initial HIV diagnosis or presentation to medical care. We defined late presentation as having a CD4 count < 350 or AIDS-defining event regardless of CD4 count. Advanced disease is defined as having a CD4 count below 200 cells/μL or the presence of an AIDS-defining illness, regardless of the CD4 count. A missed opportunity was defined as the presence of an indicator condition (IC) that suggests infection with HIV/AIDS during 3 years preceding the actual HIV diagnosis and not followed by a recommendation for HIV testing. The proportions for demographic, epidemiological, and clinical characteristics are calculated by excluding cases with missing information from the denominator. Our cohort included 150 subjects (92.7% males; 63.6% men who have sex with men (MSM); 33.3% heterosexuals; median age 30.5 years at diagnosis). 77 (51.3%) were late presenters and 53 (35.3% of all subjects, 68.8% of late presenters) had advanced HIV on presentation. Up to 76.5% of late presenters had a presentation with an HIV-related condition at a healthcare provider without getting HIV test within the previous 3 years. The most frequent ICs were weight loss, generalized lymphadenopathy, constitutional symptoms, and chronic idiopathic diarrhea. Overall mortality rate was 4% (6/150 individuals). All-cause mortality among those who presented with AIDS was 15.4% (6/39 subjects). In our setting, late presentations and missed opportunities for HIV diagnosis are common. In the Middle East, AIDS mortality remains high with a large gap in HIV testing. To effectively influence policies, comprehensive analyses should focus on estimating the preventable health and financial burdens of late HIV presentations. Another concern pertains to healthcare providers' attitudes and competencies.

Duration of delayed diagnosis in HIV/AIDS patients in Iran: a CD4 depletion model analysis

Objective

Delayed diagnosis of HIV can lead to an inappropriate response to antiretroviral therapy (ART), rapid progression of the disease, and death. It can also carry harmful effects on public health due to the increment of transmission. This study aimed to estimate the duration of delayed diagnosis (DDD) in HIV patients in Iran.

Methods

This hybrid cross-sectional cohort study was conducted on the national HIV surveillance system database (HSSD). Linear mixed effect models with random intercept, random slope, and both were used to estimate the parameters required for the CD4 depletion model to determine the best-fitted model for DDD, stratified by the route of transmission, gender, and age group.

Results

The DDD was estimated in 11,373 patients including 4,762 (41.87%) injection drug users (IDUs), 512 (4.5%) men who had sexual contact with men (MSM), 3,762 (33.08%) patients with heterosexual contacts, and 2,337 (20.55%) patients who were infected through other routes of HIV transmission. The total mean DDD was 8.41 ± 5.97 years. The mean DDD was 7.24 ± 0.08 and 9.43 ± 6.83 years in male and female IDUs, respectively. In the heterosexual contact group, DDD was obtained as 8.60 ± 6.43 years in male patients and 9.49 ± 7.17 years in female patients. It was also estimated as 9.37 ± 7.30 years in the MSM group. Furthermore, patients infected through other transmission routes were found with a DDD of 7.90 ± 6.74 years for male patients and a DDD of 7.87 ± 5.87 years for female patients.

Conclusion

A simple CD4 depletion model analysis is represented, which incorporates a pre-estimation step to determine the best-fitted linear mixed model for calculating the parameters required for the CD4 depletion model. Considering such a noticeably high HIV diagnostic delay, especially in older adults, MSM, and heterosexual contact groups, regular periodic screening is required to reduce the DDD.

HIV testing uptake, enablers, and barriers among African migrants in China: A nationwide cross-sectional study

Background

African migrants in China face social, structural, and cultural barriers to human immunodeficiency virus (HIV) testing with scarce information on their HIV testing behaviours. This study estimated the prevalence of HIV testing and its social and behavioural correlates to understand how to better provide HIV testing services for African migrants living in China.

Methods

We conducted a national cross-sectional survey among adult African migrants who lived in China for more than one month between January 19 to February 7, 2021. The survey was disseminated online through six African community organizations and via participant referrals. We collected data on HIV testing behaviours and history of HIV testing, social, and cultural factors and applied univariate and multivariable logistic regression to identify testing correlates.

Results

Among a total of 1305 participants, 72.9% (n = 951/1305) tested for HIV during their stay in China and yielded a self-reported HIV prevalence of 0.4% (n = 4/951). The most common reason for HIV testing was to comply with Chinese residence policy requirements (88.5%, n = 842/951); for not testing was "no need to be tested" (79.4%, n = 281/354). We found most African migrants have experienced low acculturation stress (54.5%, n = 750/1305), low social discrimination (65.6%, n = 856/1305), have a moderate stigma towards HIV (54.3%, n = 709/1305), and low community engagement around sexual health and HIV topics. In multivariable analysis, African migrants who were students (adjusted odds ratio (aOR) = 3.36, 95% CI = 2.40-4.71), living in student dormitories (aOR = 3.86, 95% CI = 1.51-9.84), received health services in China in past year (aOR = 1.67, 95% CI = 1.25-2.23), had lifetime sexually transmitted infections (STI) testing (aOR = 1.95, 95% CI = 1.23-3.10), had HIV testing before coming to China (aOR = 13.56, 95% CI = 9.36-19.65), and those engaged in community discussions of HIV and sexual health (aOR = 2.77, 95% CI = 1.31-5.83) were more likely to test for HIV in China.

Conclusions

Despite 73% of African migrants having tested for HIV in China, there are unmet needs and barriers identified in our study, such as language barriers. Access to HIV knowledge and testing services were the most important enablers for testing, including studentship, past STI/HIV testing, and community discussion on sexual health. Culturally appropriate and community-based outreach programs to provide information on HIV and testing venues for African migrants might be helpful to promote testing uptake.

Determinants of Late HIV Presentation at Ndlavela Health Center in Mozambique

Background: There has been tremendous progress in the fight against HIV worldwide; however, challenges persist in the control of HIV infection. These challenges include the high prevalence of late presenters. There are many disadvantages of late presentation—from reduced survival of the infected person to the risk of transmitting the infection. This research aims to analyze the factors that influence the late presentation in patients attending Ndlavela Health Center in Mozambique. Methodology: A retrospective cross-sectional study was carried out at Ndlavela Health Center including patients diagnosed with HIV between 2015 and 2020. The European Late Presenter Consensus working group definitions were used, and univariate and multivariate logistic regression were used to identify factors associated with late presentation. Results: In total, 519 participants were included in the study, of which nearly 47% were classified as late presenters. The male gender (AOR = 2.41), clinical suspicious test (AOR = 4.03), initiated by the health professional (AOR = 2.1,9), and fear of stigma (AOR = 2.80) were the main risk factors for late HIV presentation. Conclusion: Factors that are potentially determinant for late HIV presentation were identified. Actions are needed to focus on risk factors that are most likely to delay presentation.

Predictors of Mortality Among Adult HIV-Infected Patients Taking Antiretroviral Therapy (ART) in Harari Hospitals, Ethiopia

Introduction

Despite the world has made efforts, the reduction of acquired immunodeficiency syndrome (AIDS) related mortality by giving antiretroviral therapy (ART), still HIV/AIDS is killing people while they are on ART. However, the current progress and associated factors of mortality among ART-taking patients are hardly available. Therefore, this study was aimed to determine predictors of mortality among HIV-infected adult patients after starting antiretroviral therapy in Harar Hospitals, Harari region, Ethiopia.

Methods

A facility-based retrospective cohort study was employed with randomly selected 610 medical records of HIV patients on antiretroviral therapy (ART). Adjusted hazard ratio (AHR) with 95% confidence interval (CI) was used to identify predictors of mortality using multivariate Cox proportional hazard model.

Results

Among 610 medical records analyzed with a total of 1410.7 follow-up years, 67 (11%) deaths were found giving an overall mortality rate of 4.75 per 100 person-years. The independent predictor of mortality identified was ambulatory/bedridden functional status (AHR=2.48; 95% CI: 1.43-4.28), taking other than Tenofovir-based regimen (AHR=2.5,95% CI; 1.04-5.94), not taking isoniazid preventive therapy (IPT) (AHR=2.8; 95% CI: 1.61,4.71), hemoglobin <11g/dl (AHR=3.33,95% CI 1.94-5.69), and poor adherence to ART (AHR= 3.62, 95% CI: 1.87-7.0).

Conclusion

This study demonstrated that poor ART adherence, not taking IPT, and initiating ART with a non-Tenofovir-based regimen and low hemoglobin count were significantly associated with the risk of death. For this reason, addressing these all significant predictors is essential to prevent early death.

High HIV prevalence among decedents received by two high-volume mortuaries in Kisumu, western Kenya, 2019

Background

Accurate data on HIV-related mortality are necessary to evaluate the impact of HIV interventions. In low- and middle-income countries (LMIC), mortality data obtained through civil registration are often of poor quality. Though not commonly conducted, mortuary surveillance is a potential complementary source of data on HIV-associated mortality.

Methods

During April-July 2019, we assessed HIV prevalence, the attributable fraction among the exposed, and the population attributable fraction among decedents received by two high-volume mortuaries in Kisumu County, Kenya, where HIV prevalence in the adult population was estimated at 18% in 2019 with high ART coverage (76%). Stillbirths were excluded. The two mortuaries receive 70% of deaths notified to the Kisumu East civil death registry; this registry captures 45% of deaths notified in Kisumu County. We conducted hospital chart reviews to determine the HIV status of decedents. Decedents without documented HIV status, including those dead on arrival, were tested using HIV antibody tests or polymerase chain reaction (PCR) consistent with national HIV testing guidelines. Decedents aged less than 15 years were defined as children. We estimated annual county deaths by applying weights that incorporated the study period, coverage of deaths, and mortality rates observed in the study.

Results

The two mortuaries received a total of 1,004 decedents during the study period, of which 95.1% (955/1004) were available for study; 89.1% (851/955) of available decedents were enrolled of whom 99.4% (846/851) had their HIV status available from medical records and post-mortem testing. The overall population-based, age- and sex-adjusted mortality rate was 12.4 per 1,000 population. The unadjusted HIV prevalence among decedents was 28.5% (95% confidence interval (CI): 25.5–31.6). The age- and sex-adjusted mortality rate in the HIV-infected population (40.7/1000 population) was four times higher than in the HIV-uninfected population (10.2/1000 population). Overall, the attributable fraction among the HIV-exposed was 0.71 (95% CI: 0.66–0.76) while the HIV population attributable fraction was 0.17 (95% CI: 0.14–0.20). In children the attributable fraction among the exposed and population attributable fraction were 0.92 (95% CI: 0.89–0.94) and 0.11 (95% CI: 0.08–0.15), respectively.

Conclusions

Over one quarter (28.5%) of decedents received by high-volume mortuaries in western Kenya were HIV-positive; overall, HIV was considered the cause of death in 17% of the population (19% of adults and 11% of children). Despite substantial scale-up of HIV services, HIV disease remains a leading cause of death in western Kenya. Despite progress, increased efforts remain necessary to prevent and treat HIV infection and disease.

Baseline CD4 count and the time interval between the initial HIV infection and diagnosis among PLHIV in Bhutan

INTRODUCTION

CD4 count is an important predictor of disease progression, opportunities infection, deaths, and to understand the time interval between initial HIV infection to the first diagnosis. However, baseline CD4 count and the time period between initial infection and the diagnosis amongst PLHIV in Bhutan never been evaluated.

METHODS

This is a retrospective study of the diagnosed PLHIV from the existing data system from January 10 to 30, 2021. Out of 512 reported HIV cases, 488 of those who were more than or equal to 18 years old and had their CD4 count testing within 6 months before initiating ART were considered for analysis. Descriptive statistical analysis was used to analyze the characteristics of the study population and relationship were established using the χ ² Test. We have sought ethics approval and waiver for informed consent as it is the retrospective study of the client's record. The client's confidentiality was ensured by removing all the identifiers.

RESULTS

The mean CD4 was 345 cells/ml for males and females. Twenty-five percent of the clients had CD4 counts below 200, 30%, between 200 and 349, 25% between 350 and 499, and 20% above 500 cells/ml. A larger number of males showed a CD4 count below 200 cells/ml while more females showed a CD4 count more than 500 cells/ml. The mean time interval between initial infection to the first diagnosis was 4 years in males and females. However, about one-fourth were found to have been infected between 5 and 8 years before diagnosis and less than 10% were diagnosed within less than 1 year of infection.

CONCLUSIONS

The study revealed a late diagnosis of HIV infection in Bhutan thereby risking the transmission to the community and risk of severe disease and mortality. The upscaling of voluntary counseling and testing, medical screening, and alternative methods like community-based testing including HIV Self Testing for early detection needs to be implemented in the country.

Survival and Prognostic Factors of HIV-positive Patients after Antiretroviral Therapy Initiation at a Malaysian Referral Hospital

Background

Antiretroviral therapy (ART) has transformed the management of human immunodeficiency virus (HIV) infection and significantly improved survival rates, but there is lack of such survival data from Malaysia.

Objective

The objective was to determine the survival rates and prognostic factors of survival in HIV-infected adults treated with ART in Malaysia.

Materials and Methods

This retrospective cohort study considered all HIV-positive adult patients registered in Sungai Buloh Hospital, a major referral center in Malaysia, between January 1, 2007 and December 31, 2016. Then, patients were selected through a systematic sampling method. Demographic, clinical, and treatment data were extracted from electronic medical records. Person-years at risk and incidence of mortality rate per 100 person-years were calculated. The Kaplan-Meier survival curve and log-rank test were used to compare the overall survival rates. Cox proportional hazards regression was applied to determine the prognostic factors for survival.

Results

A total of 339 patients were included. The estimated overall survival rates were 93.8%, 90.4%, 84.9%, and 72.8% at 1, 3, 5, and 10 years, respectively, from ART initiation. The results of multiple Cox proportional hazard regression indicated that anemic patients were at a 3.76 times higher risk of mortality (95% confidence interval [CI]: 1.97-7.18; P < 0.001). The hazard risk was 2.09 times higher for HIV patients co-infected with tuberculosis (95% CI: 1.10, 3.96; P = 0.024).

Conclusion

The overall survival rates among HIV-infected adults in this study are higher than that from low-income countries but lower than that from high-income countries. Low baseline hemoglobin levels of <11 g/dL and tuberculosis co-infection were strong prognostic factors for survival.

Identifying risk factors for late HIV diagnosis and survival analysis of people living with HIV/AIDS in Iran (1987-2016)

Background

Late-diagnosis of HIV is a major challenge for the control and prevention of AIDS in the world. The present study aimed to specify factors associated with the late diagnosis of HIV in Iran from 1987 to 2016.

Methods

In this retrospective cohort study, data for 4402 diagnosed HIV/AIDS patients were extracted from 158 behavioral disease counseling centers of 31 Iranian provinces. We defined late diagnosis as having a CD4 count less than 350 within 3 months after diagnosis. Multiple logistic regression analysis was used to determine the factors influencing late diagnosis. Moreover, we used multivariate Cox regression to assess the association of these factors with the patients’ survival.

Results

In this study, the prevalence of late diagnosis among the patients was 58.2%. People aged 50 years and over (adjusted OR = 3.55), transmission through blood transfusion (adjusted OR = 2.89), co-infection with tuberculosis (adjusted OR = 2.06), and male gender (adjusted OR = 1.38) were the strongest predictors for late diagnosis of HIV. On the other hand, baseline CD4 (adjusted HR = 2.21), people aged 50 and over (adjusted HR = 1.81), male gender (adjusted HR = 1.76), being a widow (adjusted HR = 1.68), people with unknown transmission way (adjusted HR = 18.24), people who inject drugs (adjusted HR = 1.87), diagnosis at previous years (adjusted HR = 2.45) and co-infection with tuberculosis (adjusted OR = 1.77) significantly associated with the survival of patients.

Conclusion

The prevalence of late diagnosis is high among Iranian HIV/AIDS. The risk factors of late diagnoses include being males and aged 50 years and over, transmission through blood transfusion, and co-infection with tuberculosis. Therefore, implementation of screening programs for early diagnosis of HIV these high risk groups is recommended to Iranian health providers and policymakers.

Attrition and Its Predictors Among Adults Receiving First-Line Antiretroviral Therapy in Woldia Town Public Health Facilities, Northeast Ethiopia: A Retrospective Cohort Study

Introduction

There is an expansion and advancement of antiretroviral therapy. However, attrition of patients from HIV care is one of the major drivers of poor performance of HIV/AIDS programs, which leads to drug resistance, morbidity and mortality. The study aimed to assess the incidence of attrition and its predictors among adults receiving first-line antiretroviral therapy.

Methods

An institution-based retrospective cohort study was conducted among 634 adults receiving antiretroviral therapy, and study participants were selected using a simple random sampling technique. Data were cleaned and entered into Epi Data version 3.1 and exported to STATA 14.1 for further analysis. The predictors of attrition were identified using bivariable and multivariable Cox Proportional hazard models; then, variables at a p-value of less than 0.25 and 0.05 were included in the multivariable analysis and statistically significant, respectively.

Results

The total time observed was found to be 1807.08 person-years of observation with a median follow-up time of 2.67 years (IQR 1.25−4.67). The incidence rate of attrition was 8.36 (95% CI: 7.12−9.80) per 100 person-years. Significant predictors of attrition were being young age [adjusted hazard ratio (AHR) =2.0, 95% CI, (1.11−3.58)], nearest calendar year of ART initiation [AHR =2.32, 95% CI, (1.08–5.01)], bedridden functional status [AHR=3.25, 95% CI, (1.33−7.96)], WHO stage III [AHR=3.57, 95% CI, (1.58−8.06)] and stage IV [AHR=5.46, 95% CI, (1.97−15.13)], viral load result of ≤1000 [AHR=0.11, 95% CI, (0.06−0.23)], disclosure status [AHR=2.03, 95% CI, (1.22−3.37)] and adherence level of poor [AHR=3.19, 95 CI, (1.67−6.09)].

Conclusion

The result of this study showed that the incidence of attrition among adults receiving antiretroviral therapy was high. However, as a standard, every client who started antiretroviral therapy should be retained. Positive predictors of attrition were young age (15–24), recent year of ART initiation, baseline functional status, advanced WHO stage III and IV, no disclosure status, fair/poor adherence whereas, viral load result of ≤1000 copies/mL had a preventive effect on attrition.

Effect of the Test and Treat Strategy on Mortality Among HIV-Positive Adult Clients on Antiretroviral Treatment in Public Hospitals of Addis Ababa, Ethiopia

Background

The primary goal of antiretroviral therapy is to prevent human immune deficiency virus (HIV)-related morbidity and mortality. Deferring antiretroviral therapy (ART) until CD4 counts decline puts individuals with HIV at risk of HIV-related morbidity and mortality.

Objective

This study aims to assess the effect of the test and treat strategy on mortality among HIV-positive clients on ART in public hospitals in Addis Ababa.

Methods

A retrospective cohort study was conducted at five selected public hospitals in Addis Ababa. A cohort of 216 ART clients taken as an exposed group (test and treat" strategy) from 2017 to 2019 and 216 ART clients as an unexposed group taken from 2014 to 2017; totally, 432 clients were included in the study. Multivariate Cox regression was used to estimate the effect of the test and treat strategy on the survival of ART clients adjusting for other covariates.

Results

The 432 clients contributed to a total of 1025.17 person-years follow-up. Ninety-one (21.06%) of them died, 14.3% were unexposed and 6.7% were exposed (test and treat). The incidence of death was 92.4 and 81.8/1000 person-years in the unexposed group and exposed group, respectively, with an overall mortality rate of 88.8/1000 person-years. Besides, test and treat strategy (AHR: 0.31; 95% CI: 0.19, 0.52), baseline CD4 counts >350 cells/mm3 (AHR 0.40; 95%: CI: 0.20, 0.80), bedridden functional status (AHR 2.46; 95% CI: 1.41, 4.27), poor adherence (AHR 3.25; 95% CI: 1.410-7.51), moderate malnutrition on last visit (AHR 2.56; 95% CI: 1.30-5.04) and staying on original regimen (AHR 4.68; 95% CI 2.72, 8.07) were independent predictors of mortality.

Conclusion

Mortality among HIV patients on treatment decreased significantly since the start of the test and treat strategy. Therefore, test and treat strategy should be strengthened in all public and private facilities throughout the country.

Survival and Predictors of Mortality Among HIV Positive Adult Patients on Highly Active Antiretroviral Therapy in Public Hospitals of Kambata Tambaro Zone, Southern Ethiopia: A Retrospective Cohort Study

Background

Human Immune Deficiency Virus (HIV) infection remains the leading cause of morbidity and mortality. In Ethiopia, despite test and treat all HIV positives are adopted, a significant number of people eligible for Anti-Retroviral Therapy (ART) show up with advanced disease and at lower CD4 count. There is currently paucity of studies conducted that investigate predictors of mortality among adults on ART in the study area.

Objective

To explore Survival and predictors of mortality among adult HIV-positive patients on ART in Kambata Tambaro Zone, Ethiopia, from August 2013 to February 2019.

Methods

A health facility-based retrospective cohort study was conducted among records of 467 adult HIV-positive patients on ART selected using simple random sampling. Data were collected using standardized abstraction tool. Kaplan–Meier, Log rank tests and Cox regression model was applied to estimate survival status and identify predictors of mortality, respectively.

Results

Of the total 467 study subjects, 59 (12.63%) of them died in the study period. The median follow-up time of the cohort was 40.1 (IQR=13.6–59.0) months. The mortality rate of the cohort was 4.1 per 100 PYO. The overall survival probability of the cohort was 84.38% (95 CI=80.08–87.82) at 66 months. Bedridden function AHR=3.0 (95% CI, 1.44–6.64), Fair-adherence AHR=3.3 (95% CI, 1.50–7.07), Poor-adherence AHR=3.8 (95% CI, 1.88–7.96), presence of OIs AHR=4.2 (95% CI, 1.98–8.50), Late diagnosis (CD4 count >/=350) AHR=3.0 (95% CI, 1.91–6.42) and Immunologic failure AHR=3.5 (95% CI, 1.41–6.29) were independent predictors of time to death in Cox-Regression.

Conclusion

Late Diagnosis, poor adherence, being bedridden, having OI and Immunologic failure were independently associated with time to death. Early diagnosis to start treatment and emphasizing on close follow-up care to improve treatment adherence should be given special emphasis.

Barriers Preventing Access by Men who have Sex with Men to HIV-related health services in Southeast Asia: A Scoping Review

The objective of this scoping review was to identify and describe barriers experienced by men who have sex with men (MSM) when accessing HIV-related health care in Southeast Asia. A systematic search identified thirteen papers, which were full text reviewed and data extracted. An intersection of stigma and discrimination, fear and shame, cultural norms and societal expectations coalesce to influence the ability, either physically through lack of service provision or emotionally through personal restraint, of MSM to access HIV-related health services. Many of the factors continuing to drive the ongoing HIV epidemic across the Southeast Asia region have humanitarian origin - access to safe and non-discriminatory healthcare, education on sexual health, and not being persecuted for having a health condition. These must be addressed with an interdisciplinary response at local, government and regional level.

Effect of AIDS-defining events at initiation of antiretroviral therapy on long-term mortality of HIV/AIDS patients in Southwestern China: a retrospective cohort study

Objective

To evaluate the impact of AIDS-defining events (ADE) on long-term mortality of HIV positive individuals on antiretroviral therapy (ART), a retrospective HIV/AIDS treatment cohort study performed in Southwestern China.

Methods

The retrospective cohort was conducted among 6757 HIV/AIDS patients on ART (2NRTIs + 1NNRTI, 2NRTIs + 1PI and Single or two drugs) recruited in Guigang city, Guangxi, China, from January 2004 to December 2018. Participants were divided into ADE and non-ADE groups, and were followed-up every six months to observe treatment outcomes. Comparison of mortality between groups was performed using the log-rank test and Kaplan–Meier analysis. Cox proportional hazard regression was used to explore the risk factors of mortality. 1:1 propensity score matching (PSM) was used to balance confounding factors and adjust the mortality risk.

Results

Of 6757 participants with 29,096.06 person-years of follow-up, 16.86% (1139/6757) belonged to ADE group while the others (83.14%) belonged to the non-ADE group. The most common cause of death by ADE was disseminated mycosis (31.65%), followed by recurrent severe bacterial pneumonia (28.48%), herpes zoster (17.72%), and extra-pulmonary tuberculosis (8.86%). The mortality of the ADE group was significantly higher than that of the non-ADE group [3.45/100 person-years (95% CI 2.92–3.97) vs. 2.34/100 person-years (95% CI 2.15–2.52), P<0.001]. The death risk of the ADE group was also higher than that of the non- ADE group [adjusted hazard ratio (aHR) = 1.291, 95% CI 1.061–1.571, P = 0.011], which was confirmed by PSM analysis (aHR = 1.581, 95% CI 1.192–2.099, P = 0.002). Cox analysis indicated that ADE, older age, male gender, previous non-use of cotrimoxazole, advanced WHO clinical stage, and low baseline CD4⁺ cell count were the risk factors for death.

Conclusions

Even on ART, the mortality risk of HIV positive individuals with ADE was higher than those without ADE. Active testing, earlier diagnosis, and timely therapy with ART may reduce the death risk of ADE.
