Low-level viremia in people with HIV in Ethiopia is associated with subsequent lack of viral suppression and attrition from care
BACKGROUND: Low-level viremia during antiretroviral therapy (ART) has been associated with inferior outcomes, but knowledge on the impact of low-level viremia in the current era of dolutegravir-based ART in low-income countries is limited. OBJECTIVE: To investigate whether low-level viremia predicts virologic non-suppression and attrition from care in people with HIV receiving ART in Ethiopia. METHODS: 150 copies/mL) or low-level viremia (151-1,0…
Despite antiretroviral therapy (ART) rollout, most cases of tuberculosis among people with HIV in Adama, Ethiopia, occur before ART initiation
INTRODUCTION: Although antiretroviral therapy (ART) leads to reduced tuberculosis (TB) incidence in people with HIV (PWH), ART recipients remain at higher risk of TB compared to HIV-seronegative people. With accelerated ART rollout in sub-Saharan Africa, increasing proportions of TB cases among PWH in people receiving long-term ART have been reported. OBJECTIVE: To determine TB notifications among PWH by ART status in a mainly urban uptake area i…
HIV self-testing for men who have sex with men in Sweden. A cross-sectional study concerning interest to use HIV self-tests
BACKGROUND: HIV self-testing (HIVST) has been found to have high acceptability among men who have sex with men (MSM) internationally and might contribute to increase testing frequencies, but many countries, including Sweden, lack policies for using HIVST. OBJECTIVE: To examine interest to use and willingness to pay for HIVST, and associated factors, among MSM attending HIV testing venues in Sweden. METHOD: This cross-sectional study analyzed data…
How does HIV testing modality impact the cascade of care among persons diagnosed with HIV in Ethiopia
BACKGROUND: Despite scaling up of HIV programmes in sub-Saharan Africa, many people living with HIV (PLHIV) are unaware of their HIV status. New testing modalities, such as community-based testing, can improve test uptake, but it is uncertain whether type of testing modality affects the subsequent cascade of HIV care. OBJECTIVE: To compare linkage to care and antiretroviral treatment (ART) outcomes with regard to type of HIV testing modality. MET…
Interest in Taking HIV Pre-exposure Prophylaxis Is Associated with Behavioral Risk Indicators and Self-Perceived HIV Risk Among Men Who Have Sex with Men Attending HIV Testing Venues in Sweden
This study explored factors associated with interest in taking PrEP among men who have sex with men (MSM) attending HIV testing venues in Sweden. Data from 658 HIV-negative respondents, surveyed by a questionnaire at six sites, were analyzed descriptively and by univariable and multivariable logistic regression. A total of 453 (68.8%) of the respondents expressed interest in taking PrEP. Reporting self-perceived risk of HIV acquisition as moderat…
Development of an algorithm for determination of the likelihood of virological failure in HIV-positive adults receiving antiretroviral therapy in decentralized care
BACKGROUND: Early identification of virological failure (VF) limits occurrence and spread of drug-resistant viruses in patients receiving antiretroviral treatment (ART). Viral load (VL) monitoring is therefore recommended, but capacities to comply with this are insufficient in many low-income countries. Clinical algorithms might identify persons at higher likelihood of VF to allocate VL resources. OBJECTIVES: We aimed to construct a VF algorithm …
Growth pattern in Ethiopian infants – the impact of exposure to maternal HIV infection in relation to socio-economic factors
BACKGROUND: Infants exposed to maternal HIV infection who remain HIV-uninfected (HIV-exposed/uninfected; HIV-EU) may be at increased risk of growth retardation, which could be due both to directly HIV-related effects and to socio-economic factors overrepresented among HIV-positive women. OBJECTIVE: To investigate growth development at 9-12 months of age in HIV-EU infants participating in prevention of mother-to-child transmission (PMTCT) care com…
Retention in care among HIV-positive patients initiating second-line antiretroviral therapy: A retrospective study from an Ethiopian public hospital clinic
BACKGROUND: Access to second-line antiretroviral therapy (ART) for HIV-positive patients remains limited in sub-Saharan Africa. Furthermore, outcomes of second-line ART may be compromised by mortality and loss to follow-up (LTFU). OBJECTIVE: To determine retention in care among patients receiving second-line ART in a public hospital in Ethiopia, and to investigate factors associated with LTFU among adults and adolescents. DESIGN: HIV-positive per…
Outcome of tuberculosis treatment in HIV-positive adults diagnosed through active versus passive case-finding
BACKGROUND: The World Health Organization strongly recommends regular screening for tuberculosis (TB) in HIV-positive individuals. OBJECTIVE: To compare the outcome of anti-tuberculosis treatment (ATT) in HIV-positive adults diagnosed with TB through active case-finding (ACF) or passive case-finding (PCF). DESIGN: Antiretroviral therapy (ART)-naïve adults diagnosed with TB were included from two prospective cohort studies conducted in Ethiopia be…
Development of a clinical scoring system for assessment of immunosuppression in patients with tuberculosis and HIV infection without access to CD4 cell testing – results from a cross-sectional study i…
BACKGROUND: Currently, antiretroviral therapy (ART) is recommended for all HIV-positive patients with tuberculosis (TB). The timing of ART during the course of anti-TB treatment is based on CD4 cell counts. Access to CD4 cell testing is not universally available; this constitutes an obstacle for the provision of ART in low-income countries. OBJECTIVE: To determine clinical variables associated with HIV co-infection in TB patients and to identify …
Decentralised paediatric HIV care in Ethiopia: A comparison between outcomes of patients managed in health centres and in a hospital clinic
BACKGROUND: In order to increase access to antiretroviral therapy (ART) in HIV-infected children, paediatric HIV care has been introduced in health centres in Ethiopia, where patients are managed by health professionals with limited training. OBJECTIVE: To compare outcomes of paediatric HIV care in hospital and health centre clinics and to determine risk factors for death and loss to follow-up (LTFU). DESIGN: Retrospective comparison of patient c…
Acceptance of HIV testing among women attending antenatal care in south-western Uganda: Risk factors and reasons for test refusal
A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structured interviews were performed following pre-test cou…
