Persistent low-level viraemia is associated with non-infectious comorbidities in an observational cohort in four African countries.

Introduction: People living with HIV (PLWH) have higher rates of non-infectious comorbid diseases (NCDs) than individuals without HIV. We characterized the risk of NCDs among PLWH with undetectable viral load and persistent low-level viraemia (pLLV) in the African Cohort Study (AFRICOS). We secondarily quantified the role of immune activation in the association between LLV and NCDs.

Cumulative exposure to depressive symptoms and all-cause mortality among adults with HIV in Kenya, Nigeria, Tanzania, and Uganda.

Objective: We estimated the effects of cumulative exposure to depressive symptoms on risk of all-cause mortality among people with HIV (PWH) in four African countries.

Design: An analysis of prospective cohort data.

Methods: The African Cohort Study (AFRICOS) is a prospective cohort of people receiving care at twelve clinics in Kenya, Nigeria, Tanzania, and Uganda.

Advanced HIV disease in East Africa and Nigeria, in The African Cohort Study.

Background: Earlier antiretroviral therapy (ART) may decrease progression to advanced HIV disease (AHD) with CD4 count of <200 cells per cubic millimeter or clinical sequelae. We assessed factors associated with AHD among people living with HIV before and during the "test and treat" era.

Setting: The African Cohort Study prospectively enrolls adults with and without HIV from 12 clinics in Uganda, Kenya, Tanzania, and Nigeria.

Background: Due to digitization in the medical sector, many healthcare interactions are switched to online services. This study assessed the acceptance of video consultations (VCs) in cancer care, and determined drivers and barriers of acceptance.

Methods: A cross-sectional online-based survey study was conducted in Germany from February 2022 to February 2023.

Implications of asymptomatic malaria infections on hematologic parameters in adults living with HIV in malaria-endemic regions with varying transmission intensities.

Objectives: HIV and malaria coinfection impacts disease management and clinical outcomes. This study investigated hematologic abnormalities in malaria-asymptomatic people living with HIV (PLHIV) in regions with differing malaria transmission.

Methods: Study participants were enrolled in the African Cohort Study: two sites in Kenya, one in Uganda, and one in Nigeria.

High hepatitis B vaccination coverage among a cohort of predominantly men who have sex with men in Germany.

Incidence of hepatitis B virus (HBV) infection has declined dramatically since the introduction of the HBV vaccine, but gaps remain in coverage. We characterized factors associated with vaccination among individuals with sexual risk of HBV infection. The BRAHMS observational cohort enrolled men and transgender women, without HIV, aged 18-55 years, with behavioral vulnerability to sexually transmitted infections at 10 German outpatient clinics.

Achieving the third 95 in sub-Saharan Africa: application of machine learning approaches to predict viral failure.

Objective: Viral failure in people with HIV (PWH) may be influenced by multiple sociobehavioral, clinical, and context-specific factors, and supervised learning approaches may identify novel predictors. We compared the performance of two supervised learning algorithms to predict viral failure in four African countries.

Design: Cohort study.

Impact of weight gain with dolutegravir on antiretroviral adherence and viral suppression in four African countries.

Objective: We hypothesized that total body weight (TBW) gain after switching antiretroviral therapy (ART) regimen to tenofovir disoproxil fumarate/lamivudine/dolutegravir (TLD) may negatively impact ART adherence and viral load (VL) and therefore sought to examine these associations.

Methods: The ongoing African Cohort Study (AFRICOS) enrols people with HIV at 12 facilities in Kenya, Nigeria, Tanzania and Uganda supported by The US President's Emergency Plan for AIDS Relief. Among ART-experienced participants who switched to TLD, we used multivariable multinomial logistic regression to examine associations between pre-/post-TLD changes in percentage TBW (≥5% gain, <5% change, ≥5% loss) and changes in self-reported ART adherence (0, 1-2, ≥3 days missed doses in past 30 days) and VL [(<50 copies/mL (undetectable), 50-999 copies/mL (detectable, but suppressed), ≥1000 copies/mL (unsuppressed)].

Robotic-assisted Gynecological Surgery in Older Patients - a Comparative Cohort Study of Perioperative Outcomes.

Because of current demographic developments, a hypothesis was proposed whereby older female patients aged > 65 years can be safely operated using minimally invasive, robotic-assisted surgery, despite having more preoperative comorbidities. A comparative cohort study was designed to compare the age group ≥ 65 years (older age group, OAG) with the age group < 65 years (younger age group, YAG) after robotic-assisted gynecological surgery (RAS) in two German centers. Consecutive RAS procedures performed between 2016 and 2021 at the Women's University Hospital of Jena and the Robotic Center Eisenach to treat benign or oncological indications were included in the study.

Preparing for future European efficacy trials of interventions to prevent HIV and other sexually transmitted infections: Lessons on willingness to participate and barriers to participation from ten German clinics serving behaviorally vulnerable men who have sex with men.

Future efficacy testing of interventions to prevent HIV or other infections will require engagement of vulnerable populations. We characterized willingness to participate in a future HIV vaccine trial and barriers to participation among men who have sex with men in a 12-month German cohort study. Among 1015 participants at enrollment, 604 (60%) reported willingness, 60 (6%) were unwilling, 351 (35%) were unsure or refused to answer.

Predictors of patients' acceptance of video consultation in general practice during the coronavirus disease 2019 pandemic applying the unified theory of acceptance and use of technology model.

Background: The coronavirus disease 2019 pandemic has led to an increase in remote consultations in health care. This study aimed to assess the acceptance of video consultation as an alternative to face-to-face in-office visits in general practice (GP) and to investigate its drivers and barriers.

Methods: A cross-sectional study was conducted in Germany during the coronavirus disease 2019 pandemic from December 2020 to April 2021.

Epidemiology of Tuberculosis Among People Living With HIV in the African Cohort Study From 2013 to 2021.

Background: The prevalence and incidence of tuberculosis (TB) is high among people living with HIV (PLWH) but is often underdiagnosed in HIV programmatic settings.

Setting: President's Emergency Plan for AIDS Relief (PEPFAR)-supported research sites in Uganda, Kenya, Tanzania, and Nigeria.

Methods: All patients underwent molecular testing at entry into a longitudinal cohort of PLWH and annually thereafter.

High-risk human papillomavirus genotype distribution among women living with and at risk for HIV in Africa.

Objective: Cervical cancer is a common preventable cancer among African women living with HIV (WLWH). Molecular diagnostics for high-risk human papillomavirus (HR-HPV) genotypes are standard components of cervical cancer screening in resource-rich countries but not in resource-limited settings. We evaluated HR-HPV genotypes among women with and without HIV in four African countries to inform cervical cancer preventive strategies.

Coronavirus Antibody Responses before COVID-19 Pandemic, Africa and Thailand.

Prior immune responses to coronaviruses might affect human SARS-CoV-2 response. We screened 2,565 serum and plasma samples collected from 2013 through early 2020, before the COVID-19 pandemic began, from 2,250 persons in 4 countries in Africa (Kenya, Nigeria, Tanzania, and Uganda) and in Thailand, including persons living with HIV-1. We detected IgG responses to SARS-CoV-2 spike (S) subunit 2 protein in 1.

Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania.

Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enrolled in the African Cohort Study (AFRICOS; January 2013-February 2020).

Non-communicable diseases by age strata in people living with and without HIV in four African countries.

Introduction: Non-communicable diseases (NCDs) are an important driver of morbidity among ageing people living with HIV (PLWH). We examined the composite role of age and HIV status on NCDs in people living with and without HIV.

Methods: The African Cohort Study (AFRICOS) prospectively enrols participants aged ≥15 years with and without HIV at 12 sites in Kenya, Tanzania, Uganda and Nigeria.

Assessment of tuberculosis disease activity in people infected with and living with HIV: A longitudinal cohort study.

Background: Early detection of asymptomatic incipient tuberculosis (TB) could improve clinical outcomes and reduce the spread of infection, particularly in HIV endemic settings. This study assessed TB disease activity over 5 years in people living with HIV co-infected with using a surrogate biomarker.

Methods: Between Jan 1, 2013 and Aug 31, 2018, 2014 people living with HIV were screened annually for active TB using the Xpert MTB/RIF diagnostic assay in 11 clinics in Kenya, Tanzania, Uganda, and Nigeria.

Transitioning women to first-line preferred TLD regimen is lagging in Sub-Saharan Africa.

Introduction: In 2019, the World Health Organization (WHO) recommended tenofovir disoproxil fumarate-lamivudine-dolutegravir (TLD) as the preferred first line regimen for adults and adolescents regardless of childbearing status. Nevertheless, final eligibility is determined by local policies which may vary from WHO recommendations. We examined TLD transition by gender across five PEPFAR-supported HIV care programs in sub-Saharan Africa.

Weight gain during the dolutegravir transition in the African Cohort Study.

Introduction: Dolutegravir (DTG) has become a preferred component of first-line antiretroviral therapy (ART) in many settings but may be associated with excess weight gain. We evaluated changes in weight and body mass index (BMI) after switch to single-tablet tenofovir/lamivudine/dolutegravir (TLD) by people living with HIV (PLWH) in four African countries.

Methods: The African Cohort Study (AFRICOS) prospectively follows adults with and without HIV in Kenya, Uganda, Tanzania and Nigeria.

HIV pre-exposure prophylaxis was associated with no impact on sexually transmitted infection prevalence in a high-prevalence population of predominantly men who have sex with men, Germany, 2018 to 2019.

IntroductionDespite increased use of pre-exposure prophylaxis (PrEP) in Germany, HIV infection rates are not declining and little is known about how this prevention method affects the prevalence of sexually transmitted infections (STI) among men who have sex with men (MSM).AimWe studied, in a large multicentre cohort, STI point prevalence, co-infection rates, anatomical location and influence of PrEP.MethodsThe BRAHMS study was a prospective cohort study conducted at 10 sites in seven major German cities that enrolled MSM reporting increased sexual risk behaviour.

Clinical similarities and differences between two large HIV cohorts in the United States and Africa.

Background: Washington, DC, and sub-Saharan Africa are both affected by generalized HIV epidemics. However, care for persons living with HIV (PLWH) and clinical outcomes may differ in these geographically and culturally diverse areas. We compared patient and clinical site characteristics among adult persons living with HIV (PLWH) enrolled in two longitudinal HIV cohort studies-the African Cohort Study (AFRICOS) and the DC Cohort.

Non-communicable diseases in older people living with HIV in four African countries: a cohort study.

Background: The lifespan of people living with HIV is increasing, and non-communicable diseases (NCDs) are becoming an important driver of morbidity in this population. We examined the prevalence of NCDs in older people with HIV and factors associated with development of NCDs.

Methods: The African Cohort Study is a prospective cohort enrolling adults with and without HIV at 12 sites in Kenya, Tanzania, Uganda, and Nigeria.

Clinical factors and outcomes associated with immune non-response among virally suppressed adults with HIV from Africa and the United States.

A significant minority of people living with HIV (PLWH) achieve viral suppression (VS) on antiretroviral therapy (ART) but do not regain healthy CD4 counts. Clinical factors affecting this immune non-response (INR) and its effect on incident serious non-AIDS events (SNAEs) have been challenging to understand due to confounders that are difficult to control in many study settings. The U.

Routine HIV clinic visit adherence in the African Cohort Study.

Background: Retention in clinical care is important for people living with HIV (PLWH). Evidence suggests that missed clinic visits are associated with interruptions in antiretroviral therapy (ART), lower CD4 counts, virologic failure, and overlooked coinfections. We identified factors associated with missed routine clinic visits in the African Cohort Study (AFRICOS).
