Background: During the 2020 COVID-19 lockdown, patients included in the Interprofessional Medication Adherence Program (IMAP) in Switzerland continued to use electronic monitors (EMs) that registered ...daily drug-dose intake. We aimed to understand to what extent patients' medication implementation (ie, the extent to which the patient took the prescribed medicine), measured with EMs, was impacted by the lockdown. Methods: Patients participating in the IMAP were diagnosed with diabetic kidney disease (DKD), solid cancer, human immunodeficiency virus (HIV) and miscellaneous long-term diseases (MLTD). Patient implementation was defined through a proxy: if all patient EMs were opened at least once daily, implementation was considered active (=1), and no implementation was considered (=0) otherwise. Implementation before (from December 2019 to March 2020), during (March to June 2020) and after (June to September 2020) the lockdown was compared. Subanalyses were performed according to the patients' diseases. Subanalyses were performed in patients who used at least one EM in 2018-2019 during the same periods (defined as winter, spring and summer). The logistic regression models used to estimate medication implementation according to the period were fitted using generalized estimating equations. Results: In 2020, patient implementation (n = 118) did not differ significantly before versus during (OR = 0.98, 95% CI: 0.84-1.15, p = 0.789) and before versus after (OR = 0.91, 95% CI: 0.79-1.06, p = 0.217) the lockdown. These findings remained stable when separately analyzing the implementation of patients with HIV (n = 61), DKD (n = 25) or MLTD (n = 22). Too few patients with cancer were included (n = 10) to interpret the results. In 2019, the implementation of 61/118 (51.7%) patients was significantly lower during summertime versus wintertime (OR = 0.73, 95% CI: 0.60-0.89, p = 0.002). Conclusion: Medication implementation remained steady before, during and after the lockdown in 2020. The IMAP before, during and after the lockdown may have supported the adherence of most patients, by ensuring continuity of care during periods of routine disturbances.

Objectives
Late presentation (LP) to HIV care disproportionally affects individuals from sub‐Saharan Africa (SSA). We explored the reasons for late presentation to care among this group of patients ...in the Swiss HIV Cohort Study.
Methods
The prevalence of LP was compared between patients from Western Europe (WE) and those from SSA enrolled between 2009 and 2012. Patients were asked about HIV testing, including access to testing and reasons for deferring it, during face‐to‐face interviews.
Results
The proportion of LP was 45.8% (435/950) among patients from WE, and 64.6% (126/195) among those from SSA (P < 0.001). Women from WE were slightly more likely to present late than men (52.6% versus 44.5%, respectively; P = 0.06), whereas there was no sex difference in patients from SSA (65.6% versus 63.2%, respectively; P = 0.73). Compared with late presenters from WE, those from SSA were more likely to be diagnosed during pregnancy (9.1% versus 0%, respectively; P < 0.001), but less likely to be tested by general practitioners (25.0% versus 44.6%, respectively; P = 0.001). Late presenters from SSA more frequently reported ‘not knowing about anonymous testing possibilities’ (46.4% versus 27.3%, respectively; P = 0.04) and ‘fear about negative reaction in relatives’ (39.3% versus 21.7%, respectively; P = 0.05) as reasons for late testing. Fear of being expelled from Switzerland was reported by 26.1% of late presenters from SSA.
Conclusions
The majority of patients from SSA were late presenters, independent of sex or education level. Difficulties in accessing testing facilities, lack of knowledge about HIV testing and fear‐related issues are important drivers for LP in this population.
In 2014, there were 36.9 million people worldwide living with human immunodeficiency virus (PLWH), of whom 17.1 million did not know they were infected. Whilst the number of new human ...immunodeficiency virus (HIV) infections has declined globally since 2000, there are still regions where new infection rates are rising, and diagnosing HIV early in the course of infection remains a challenge. Late presentation to care in HIV refers to individuals newly presenting for HIV care with a CD4 count below 350 cells/µl or with an acquired immune deficiency syndrome (AIDS)-defining event. Late presentation is associated with increased patient morbidity and mortality, healthcare costs and risk of onward transmission by individuals unaware of their status. Further, late presentation limits the effectiveness of all subsequent steps in the cascade of HIV care. Recent figures from 34 countries in Europe show that late presentation occurs in 38.3% to 49.8% of patients newly presenting for care, depending on region. In Switzerland, data from patients enrolled in the Swiss HIV Cohort Study put the rate of late presentation at 49.8% and show that patients outside established HIV risk groups are most likely to be late presenters. Provider-initiated testing needs to be improved to reach these groups, which include heterosexual men and women and older patients. The aim of this review is to describe the scale and implications of late presentation using cohort data from Switzerland and elsewhere in Europe, and to highlight initiatives to improve early HIV diagnosis. The importance of recognising indicator conditions and the potential for missed opportunities for HIV testing is illustrated in three clinical case studies.
Abstract
Background
Integrase strand transfer inhibitors (INSTIs) have been associated with an increased risk for cardiovascular disease (CVD) events. We investigated the impact of starting ...INSTI-based antiretroviral therapy (ART) on CVD events among treatment-naïve people with human immunodeficiency virus using a target trial framework, which reduces the potential for confounding and selection bias.
Methods
We included Swiss HIV Cohort Study participants who were ART-naïve after May 2008, when INSTIs became available in Switzerland. Individuals were categorized according to their first ART regimen (INSTI vs other ART) and were followed from ART start until the first of CVD event (myocardial infarction, stroke, or invasive cardiovascular procedure), loss to follow-up, death, or last cohort visit. We calculated hazard ratios and risk differences using pooled logistic regression models with inverse probability of treatment and censoring weights.
Results
Of 5362 participants (median age 38 years, 21% women, 15% of African origin), 1837 (34.3%) started INSTI-based ART, and 3525 (65.7%) started other ART. Within 4.9 years (interquartile range, 2.4–7.4), 116 CVD events occurred. Starting INSTI-based ART was not associated with an increased risk for CVD events (adjusted hazard ratio, 0.80; 95% confidence interval CI, .46–1.39). Adjusted risk differences between individuals who started INSTIs and those who started other ART were −0.17% (95% CI, −.37 to .19) after 1 year, −0.61% (−1.54 to 0.22) after 5 years, and −0.71% (−2.16 to 0.94) after 8 years.
Conclusions
In this target trial emulation, we found no difference in short- or long-term risk for CVD events between treatment-naïve people with human immunodeficiency virus who started INSTI-based ART and those on other ART.
In treatment-naïve people with HIV, starting antiretroviral therapy containing integrase strand transfer inhibitors did not lead to an increased risk for cardiovascular disease events in this target trial emulation from the Swiss HIV Cohort Study.

People living with human immunodeficiency virus (PLWH) have significantly increased risk for cardiovascular disease in part due to inflammation and immune dysregulation. Clonal hematopoiesis of ...indeterminate potential (CHIP), the age-related acquisition and expansion of hematopoietic stem cells due to leukemogenic driver mutations, increases risk for both hematologic malignancy and coronary artery disease (CAD). Since increased inflammation is hypothesized to be both a cause and consequence of CHIP, we hypothesized that PLWH have a greater prevalence of CHIP. We searched for CHIP in multi-ethnic cases from the Swiss HIV Cohort Study (SHCS, n = 600) and controls from the Atherosclerosis Risk in the Communities study (ARIC, n = 8111) from blood DNA-derived exome sequences. We observed that HIV is associated with a twofold increase in CHIP prevalence, both in the whole study population and in a subset of 230 cases and 1002 matched controls selected by propensity matching to control for demographic imbalances (SHCS 7%, ARIC 3%, p = 0.005). We also observed that ASXL1 is the most commonly mutated CHIP-associated gene in PLWH. Our results suggest that CHIP may contribute to the excess cardiovascular risk observed in PLWH.
Advancements in access to antiretroviral therapy (ART) and human immunodeficiency virus (HIV) care have led to a decline in acquired immunodeficiency syndrome (AIDS)-related deaths among people with ...HIV (PWH) in Switzerland. However, data on the ongoing changes in causes of death among PWH over the past 15 years is scarce.
We investigated all reported deaths in the Swiss HIV Cohort Study between 2005-2022. Causes of death were categorized using the Coding Causes of Death in HIV protocol. The statistical analysis included demographic stratification to identify time trends and logistic regression models to determine associated factors for the underlying cause of death.
In total, 1630 deaths were reported, with 23.7% of individuals assigned female at birth. Out of these deaths, 147 (9.0%) were HIV/AIDS-related, 373 (22.9%) due to non-AIDS, non-hepatic (NANH) cancers, 166 (10.2%) liver-related, and 158 (9.7%) cardiovascular-related. The median age at death increased from 45.0 40.0,53.0 years in 2005-2007 to 61.0 56.0,69.5 years in 2020-2022. HIV/AIDS and liver-related causes of death decreased, whereas deaths from NANH cancers increased, and cardiovascular-related deaths remained relatively stable.
The proportionally decreasing HIV/AIDS and liver-related deaths showcase the effectiveness of ART, comprehensive HIV patient care, and interventions targeting hepatitis C virus co-infection. Future research should focus on managing cancer and cardiovascular-related conditions as the new leading causes of death among PWH. Comprehensive healthcare strategies focusing on non-AIDS-related comorbidities, cancer management, and sustaining liver and cardiovascular health are needed to bridge the ongoing health disparities between PWH and the general population.
Abstract
Background
The Swiss HCVree Trial (NCT 02785666) was conducted in 2015–2017 with the goal of implementing a population-based systematic hepatitis C virus (HCV) micro-elimination program ...among men who have sex with men (MSM) with human immunodeficiency virus (HIV) enrolled in the Swiss HIV Cohort Study (SHCS). The trial led to a 91% and 77% decline of HCV prevalence and incidence, respectively. The long-term effect of this HCV micro-elimination program is yet to be explored.
Methods
All MSM enrolled in the SHCS were screened for HCV RNA using stored plasma samples obtained in 2019, termed “Swiss HCVree Post” screen. The incidence of HCV infection over time was assessed using additional information on HCV testing routinely collected in the SHCS. Characteristics of participants with replicating HCV infection were analyzed.
Results
The point-prevalence of “Swiss HCVree Post” (N = 4641) was 0.6%, reflecting a decline of 48% compared to the end of the Swiss HCVree Trial where the prevalence was 1.2%. Further, the incidence of HCV among MSM in the SHCS declined from 0.31/100 person-years (py) (95% confidence interval CI .17, .55) in 2017 to 0.19/100 py (95% CI .09, .39) in 2019.
Conclusions
A systematic HCV RNA-based screening among MSM with HIV conducted 2 years after the Swiss HCVree Trial revealed a sustained effect and further decline of the prevalence and incidence of replicating HCV infection. This indicates that the Swiss HCVree Trial was successful in curbing the HCV epidemic among MSM with HIV in Switzerland.

The Agricultural Act of 2014 (Farm Bill) is a critical part of the economic safety net for U.S. crop and dairy producers through 2018. Passage of the Farm Bill marked a change in philosophy regarding ...producer and landowner decisions about program choices. The shift was away from nearly 20 years of fixed annual payments based on historical production to decisions based on risk management for producers. This change created the most complicated set of decisions producers have had to make in recent decades. Because of these changes, Secretary of Agriculture Vilsack (2014) indicated the need to establish an educational effort to enable all producers to understand their options and make informed decisions related to both the 2015 crop year and the various program choices. The primary focus of the educational effort is on agricultural producers' needs and program outcomes and impacts. This article highlights a unique multiorganizational statewide collaboration that addressed the Farm Bill educational effort in Minnesota.
Abstract Background Antiretroviral therapy (ART)-related weight gain is of particular concern in people with HIV (PWH). Although weight gain was observed among PWH receiving tenofovir alafenamide ...(TAF), little is known about the potential reversibility after TAF discontinuation. We evaluated weight and metabolic changes 12 months after TAF discontinuation in the Swiss HIV Cohort Study. Methods We included participants who received at least 6 months of TAF-containing ART between January 2016 and March 2023. Using multivariable mixed-effect models, changes in weight and lipid levels were compared between individuals who continued TAF and those who switched to one of the following TAF-free regimens: (1) tenofovir disoproxil fumarate (TDF)-based ART, (2) dolutegravir/lamivudine (DTG/3TC), or (3) long-acting cabotegravir/rilpivirine (CAB/RPV). Results Of 6555 participants (median age 54 years, 24.3% female, 13% Black), 5485 (83.7%) continued, and 1070 (16.3%) stopped TAF. Overall, discontinuing TAF was associated with an adjusted mean weight change of −0.54 kg (95% confidence interval CI −.98 to −.11) after 12 months. In stratified analyses, switching from TAF to TDF led to an adjusted mean weight decrease of −1.84 kg (95% CI −2.72 to −.97), and to a decrease in mean total cholesterol (−0.44 mmol/L) and triglycerides (−0.38 mmol/L) after 12 months. Switching from TAF-based ART to DTG/3TC (−0.17 kg, 95% CI −.82 to .48) or long-acting CAB/RPV (−0.64 kg, 95% CI −2.16 to .89) did not lead to reductions in weight. Conclusions Replacing TAF with TDF in PWH led to a decrease in body weight and an improved lipid profile within 1 year. Weight changes were not observed among individuals who switched to DTG/3TC or long-acting CAB/RPV.
