Introduction
In many countries, mortality due to suicide is higher among people living with HIV than in the general population. We aimed to analyse trends in suicide mortality before and after the ...introduction of triple combination antiretroviral therapy (cART), and to identify risk factors associated with death from suicide in Switzerland.
Methods
We analysed data from the Swiss HIV Cohort Study from the pre‐cART (1988‐1995), earlier cART (1996‐2008) and later cART (2009‐2017) eras. We used multivariable Cox regression to assess risk factors for death due to suicide in the ART era and computed standardized mortality ratios (SMRs) to compare mortality rates due to suicide among persons living with HIV with the general population living in Switzerland, using data from the Swiss National Cohort.
Results and Discussion
We included 20,136 persons living with HIV, of whom 204 (1.0%) died by suicide. In men, SMRs for suicide declined from 12.9 (95% CI 10.4‐16.0) in the pre‐cART era to 2.4 (95% CI 1.2‐5.1) in the earlier cART and 3.1 (95% CI 2.3‐4.3) in the later cART era. In women, the corresponding ratios declined from 14.2 (95% CI 7.9‐25.7) to 10.2 (3.8‐27.1) and to 3.3 (95% CI 1.5‐7.4). Factors associated with death due to suicide included gender (adjusted hazard ratio 0.58 (95% CI 0.38‐0.87) comparing women with men), nationality (1.95 (95% CI 1.34‐2.83) comparing Swiss with other), Centers for Disease Control and Prevention clinical stage (0.33 (95% CI 0.24‐0.46) comparing stage A with C), transmission group (2.64 (95% CI 1.71‐4.09) for injection drug use and 2.10 (95% CI 1.36‐3.24) for sex between men compared to other), and mental health (2.32 (95% CI 1.71‐3.14) for a history of psychiatric treatment vs. no history). There was no association with age.
Conclusions
Suicide rates have decreased substantially among people living with HIV in the last three decades but have remained about three times higher than in the general population since the introduction of cART. Continued emphasis on suicide prevention among men and women living with HIV is important.

Background & Aims
Hepatitis C virus (HCV) therapies with interferon‐free second‐generation direct‐acting antivirals (DAAs) are highly effective and well tolerated. They have the potential to increase ...treatment eligibility and efficacy in HIV‐infected patients. We assessed the impact of DAAs on treatment uptake and efficacy, as well as its impact on the burden of liver disease in the Swiss HIV Cohort Study (SHCS).
Methods
We describe clinical and virological characteristics of patients treated with second‐generation DAAs. We compared treatment incidence, sustained virological response (SVR)12 and liver fibrosis stages between three time periods: period 1, 01/2009‐08/2011 (prior to the availability of DAAs); period 2, 09/2011‐03/2014 (first generation DAAs); period 3, 04/2014‐12/2015 (second generation DAAs).
Results
At the beginning of the third period, 876 SHCS participants had a chronic HCV infection of whom 180 (20%) started treatment with a second‐generation DAA. Three‐quarters of them had advanced liver fibrosis (Metavir ≥ F3) of whom 80% were cirrhotics. SVR12 was achieved in 173/180 (96%) patients, three patients died and four experienced a virological failure. Over the three time periods, treatment uptake (4.5/100 py, 5.7/100 py, 22.4/100 py) and efficacy (54%, 70%, 96% SVR12) continuously increased. The proportion of cirrhotic patients with replicating HCV infection in the SHCS declined from 25% at the beginning to 12% at the end of the last period.
Conclusions
After the introduction of second‐generation DAAs, we observed an increase in treatment uptake and efficacy which resulted in a significant reduction in the number of cirrhotic patients with a replicating HCV infection in the SHCS.

Objectives
We previously demonstrated an association between tenofovir disoproxil fumarate (TDF) and chronic liver enzyme elevation in the D:A:D study. The objective of the study was to assess ...changes in alanine aminotransferase (ALT) levels after switching from TDF to tenofovir alafenamide (TAF).
Methods
We included Swiss HIV Cohort Study participants who switched from TDF to TAF with two or more ALT values in the 24 months before and two or more values in the 24 months after replacing TDF with TAF. Individuals with replicating viral hepatitis were excluded. Uni‐ and multivariable linear mixed models were used to explore changes in ALT values associated with switching from TDF to TAF, and to assess potential modifying effects.
Results
A total of 1712 participants were included, contributing 6169 ALT values before and 5482 after switching. Median (interquartile range, IQR) age was 50 (42–57) years, and 75% were male. Median (IQR) ALT was 28 (22–38) U/L before and 24 (19–32) U/L after replacing TDF with TAF. ALT values decreased by 3.7 U/L (95% confidence interval: 3.2–4.2) after the switch. The median drop was larger in patients with chronic ALT elevation (defined as two or more elevated values for ≥ 6 months) compared with patients with normal ALT values (17.8 vs. 3.3 U/L, P < 0.001). We did not identify any major effect modifications of the ALT change with any of the potential variables studied.
Conclusions
Replacing TDF with TAF in HIV‐monoinfected people led to a significant decrease in ALT values. Findings were not significantly affected by known risk factors for hepatotoxicity.

Antiretroviral therapy has transformed HIV infection from a deadly into a chronic condition. Aging people with HIV (PWH) are at higher risk of polypharmacy, potential drug-drug interactions (DDIs), ...and potentially inappropriate medications (PIMs). This study aims to compare prescribed drugs, polypharmacy, and potential DDIs between young (<65 years old) and elderly (≥65 years old) PWH. The prevalence of PIMs was assessed in elderly.
PWH from 2 centers within the Swiss HIV Cohort Study were asked to fill in a form with all their current medications. Polypharmacy was defined as being on ≥5 non-HIV drugs. PIMs were evaluated using Beers criteria. Potential DDIs for the most prescribed therapeutic classes were screened with the Liverpool interaction database.
Among the 996 PWH included, 122 were ≥65 years old. Polypharmacy was more frequent in the elderly group (44% vs 12%). Medications and potential DDIs differed according to the age group: cardiovascular drugs and related potential DDIs were more common in the elderly group (73% of forms included ≥1 cardiovascular drug; 11% of cardiovascular drugs involved potential DDIs), whereas central nervous system drugs were more prescribed and involved in potential DDIs in younger PWH (26%, 11%). Potential DDIs were mostly managed through dosage adjustments. PIMs were found in 31% of the elderly group.
Potential DDIs remain common, and PIMs constitute an additional burden for the elderly. It is important that prescribers develop and maintain a proactive approach for the recognition and management of DDIs and other prescribing issues frequently encountered in geriatric medicine.
Abstract
Background
Incomplete antiretroviral therapy (ART) adherence, even if sufficient to maintain viral suppression, is associated with enhanced inflammation in persons with HIV (PWH). However, ...its clinical implications remain unknown.
Methods
PWH enrolled in the Swiss HIV Cohort Study without a history of cardiovascular disease (CVD) who initiated ART between 2003 and 2018 and had viral suppression (<50 copies/mL) for ≥6 months were evaluated. The association between incomplete self-reported ART adherence (≥1 or ≥2 missed doses in the last month) and (1) any CVD event (myocardial infarction, revascularization, cerebral hemorrhage, stroke, and/or death due to CVD event) or (2) non-CVD-related death was evaluated using adjusted Cox proportional hazards models.
Results
A total of 6971 PWH (74% male) were included in the analysis (median age interquartile range {IQR}, 39 32–47 years). The median (IQR) follow-up was 8 (4–11) years, with 14 (8–23) adherence questionnaires collected per participant. In total, 205 (3%) participants experienced a CVD event, and 186 (3%) died a non-CVD-related death. In an adjusted competing risk model where missing data were imputed, missing ≥1 ART dose showed an increased, but not statistically significant, risk for CVD events (hazard ratio HR, 1.23; 95% CI, 0.85–1.79; P = .28). Non-CVD-related mortality showed a statistically significantly increased risk with missing ≥1 ART dose (HR, 1.44; 95% CI, 1.00–2.07; P = .05) and missing ≥2 ART doses (HR, 2.21; 95% CI, 1.37–3.57; P = .001).
Conclusions
Incomplete ART adherence was significantly associated with an increased risk for non-CVD-related mortality in PWH with virologic suppression. This highlights the potential role of nonadherence to ART as a driver of non-AIDS clinical outcomes.
Objectives
Following clearance of incident hepatitis C virus (HCV) infections, HCV antibody levels may decline, resulting in seroreversion. It is unclear to what extent HCV antibody level ...trajectories differ between patients with treatment‐induced sustained virological response (SVR), those with spontaneous clearance and those with untreated replicating HCV infection. We investigated HCV antibody level dynamics in HIV‐infected MSM with different clinical outcomes.
Methods
We investigated anti‐HCV antibody level dynamics following an incident HCV infection in 67 HIV‐infected men who have sex with men (MSM) with different clinical outcomes: SVR (n = 33), spontaneous clearance (n = 12), and untreated replicating infection (n = 22). Antibody levels were measured at the time of HCV diagnosis, and at yearly intervals for 3 years thereafter.
Results
At baseline, median HCV antibody levels were similar in the three groups: 13.4, 13.8 and 13.5 sample to cut‐off (S/CO) for SVR, spontaneous clearance and untreated infection, respectively. Over 3 years of follow‐up, SVR was associated with a more pronounced decrease in anti‐HCV levels compared with spontaneous clearance and untreated infection median decline 71% interquartile range (IQR: 43–87%), 38% (IQR: 29–60%) and 12% (IQR: 9–22%), respectively; P < 0.001. Seroreversions occurred in five of 33 (15%) patients with SVR and in one of 12 (8%) with spontaneous clearance. A shorter delay between time of infection and treatment start correlated with higher rates of decline in antibody levels. Seven patients experienced a reinfection.
Conclusions
Treatment‐induced HCV clearance was associated with a more pronounced decline in anti‐HCV antibody levels and with higher rates of seroreversion compared with spontaneous clearance or untreated replicating HCV infection among HIV‐infected MSM with incident HCV infections. Rapid clearance of HCV RNA following early HCV treatment might impair the development of persistent antibody titres.

Objectives
Women with HIV infection are mainly of reproductive age and need safe, effective and affordable contraception to avoid unintended pregnancies. The aim of this study was to evaluate ...contraceptive use and unintended pregnancies in this population in Switzerland.
Methods
A self‐report anonymous questionnaire on contraceptive methods, adherence to them, and unintended pregnancies was completed by women included in the Swiss HIV Cohort Study (SHCS) between November 2013 and June 2014. Sociodemographic characteristics and information related to combined antiretroviral therapy and HIV disease status were obtained from the SHCS database.
Results
Of 462 women included, 164 (35.5%) reported not using any contraception. Among these, 65 (39.6%) reported being sexually active, although 29 (44.6%) were not planning a pregnancy. Of 298 women using contraception, the following methods were reported: condoms, 219 (73.5%); oral hormonal contraception, 32 (10.7%); and intrauterine devices, 28 (9.4%). Among all women on contraception, 32 (10.7%) reported using more than one contraceptive method and 48 (16%) had an unintended pregnancy while on contraception (18, condoms; 16, oral contraception; four, other methods). Of these, 68.1% terminated the pregnancy and almost half (43.7%) continued using the same contraceptive method after the event.
Conclusions
Family planning needs in HIV‐positive women are not fully addressed because male condoms remained the predominant reported contraceptive method, with a high rate of unintended pregnancies. It is of utmost importance to provide effective contraception such as long‐acting reversible contraceptives for women living with HIV.

Syphilis is re-emerging globally in general and HIV-infected populations, and repeated syphilis episodes may play a central role in syphilis transmission among core groups. Besides sexual behavioral ...factors, little is known about determinants of repeated syphilis episodes in HIV-infected individuals-including the potential impact of preceding syphilis episodes on subsequent syphilis risk.
In the prospective Swiss HIV cohort study, with routine syphilis testing since 2004, we analyzed HIV-infected men who have sex with men (MSM). Our primary outcome was first and repeated syphilis episodes. We used univariable and multivariable Andersen-Gill models to evaluate risk factors for first and repeated incident syphilis episodes.
Within the 14-year observation period, we included 2513 HIV-infected MSM with an initially negative syphilis test. In the univariable and multivariable analysis, the number of prior syphilis episodes (adjusted hazard ratio aHR per 1-episode increase, 1.15; 95% confidence interval CI, 1.01-1.31), having occasional sexual partners with or without condomless anal sex (aHR, 4.99; 95% CI, 4.08-6.11; and aHR, 2.54; 95% CI, 2.10-3.07), and being currently on antiretroviral therapy (aHR, 1.62; 95% CI, 1.21-2.16) were associated with incident syphilis.
In HIV-infected MSM, we observed no indication of decreased syphilis risk with repeated syphilis episodes. The extent of sexual risk behavior over time was the strongest risk factor for repeated syphilis episodes. The observed association of antiretroviral therapy with repeated syphilis episodes warrants further immunological and epidemiological investigation.
