Population Pharmacokinetics of Cabotegravir Following Oral Administration and Long-Acting Intramuscular Injection in Real-World People with HIV.

Long-acting cabotegravir has been studied mainly in the stringent framework of clinical trials, which does not necessarily reflect the situation of people with HIV (PWH) in routine clinical settings. The present population pharmacokinetic analysis aims to build real-world reference percentile curves of cabotegravir concentrations, accounting for patient-related factors that may affect cabotegravir exposure. The second objective is to simulate whether dosing interval adjustments of cabotegravir could be considered in specific subpopulations.

Real-world trough concentrations and effectiveness of long-acting cabotegravir and rilpivirine: a multicenter prospective observational study in Switzerland.

Background: The efficacy and tolerability of long-acting cabotegravir and rilpivirine were demonstrated in Phase III trials. However, low concentrations combined with other risk factors have been associated with an increased risk of virologic failure. This study aims to verify whether drug concentrations measured in a real-world setting are consistent with those previously reported.

Worm globalization.

We report the first case of eosinophilic pleural effusion due to Anisakis spp. infection in a 39-years-old European subject hospitalized for worsening dyspnoea and abdominal and thoracic pain. Lung CT scan showed bilateral pleural effusion; thoracentesis revealed significant eosinophilia (45%), with normal eosinophils in the blood.

Parvimonas micra a new potential pathogen in hospitalized patients: a case series from 2015-2022.

Parvimonas micra isolations are usually part of polymicrobial infections and the pathogenic role of this microrganism is still debated. We describe here a large series of hospitalized patients diagnosed with Parvimonas micra infections and discuss the clinical and therapeutic management and the outcome of these infections.

A case of spondylodiscitis by Ureaplasma urealyticum in an immunocompetent adult with spine stabilization.

Ureaplasma urealyticum is part of the normal genital flora of many sexually experienced people, thereby it is mostly associated with genitourinary tract infections. Here, we present the first case reported in the literature of spondylodiscitis caused by U. urealyticum in a 62-year-old immunocompetent subject.

Anticholinergic and Sedative Medications Are Associated With Neurocognitive Performance of Well Treated People With Human Immunodeficiency Virus.

Background: We previously showed that anticholinergic (ACH) medications contribute to self-reported neurocognitive impairment (NCI) in elderly people with human immunodeficiency virus (PWH). The current cross-sectional study further evaluated the effect of ACH and sedative drugs on neurocognitive function in PWH who underwent comprehensive neuropsychological evaluation.

Methods: A medication review was performed in PWH enrolled in the prospective Neurocognitive Assessment in Metabolic and Aging Cohort within the Swiss HIV Cohort Study.

Neurocognitive course at 2-year follow-up in a Swiss cohort of people with well-treated HIV.

Objective: The aim of this study was to examine neurocognitive course over time among people with well treated HIV.

Design: The Neurocognitive Assessment in the Metabolic and Aging Cohort (NAMACO) study is an ongoing, prospective, longitudinal, multicenter and multilingual study within the Swiss HIV Cohort Study (SHCS). Participants undergo neuropsychological assessment at baseline and two-yearly follow-up.

Abdominal actinomycosis after reparative surgery for cholecystogastric fistula in an immunosuppressed patient.

A male patient, aged over 75 years, was referred to the emergency room for pain in his right hypochondrium. This pain, which persisted for approximately 3 days, radiated to his right flank and right iliac quadrant and worsened after meals. The patient reported no nausea, vomiting, diarrhoea, fever or recent traumatic events.

Alcohol consumption and neurocognitive deficits in people with well-treated HIV in Switzerland.

Background: Hazardous alcohol consumption and HIV infection increase the risk of neurocognitive impairment (NCI). We examined the association between alcohol consumption and specific neurocognitive domain function in people with HIV (PWH) taking modern antiretroviral therapy.

Methods: The Neurocognitive Assessment in the Metabolic and Aging Cohort (NAMACO) study is a prospective, longitudinal, multicentre and multilingual (French, German and Italian) study of patients aged ≥45 years old enrolled in the Swiss HIV Cohort Study (SHCS).

The association between depressive symptoms and neurocognitive impairment in people with well-treated HIV in Switzerland.

Background: Depression may contribute to neurocognitive impairment (NCI) in people with HIV (PWH). Attributing NCI to depression rather than to HIV is complicated as depression may be both a causal factor and an effect of NCI. This study aimed to determine the association between depressive symptoms and NCI among PWH with well-controlled infection.

Cross-Sectional and Cumulative Longitudinal Central Nervous System Penetration Effectiveness Scores Are Not Associated With Neurocognitive Impairment in a Well Treated Aging Human Immunodeficiency Virus-Positive Population in Switzerland.

Background: Neurocognitive impairment (NCI) in people with human immunodeficiency virus (PWH) remains a concern despite potent antiretroviral therapy (ART). Higher central nervous system (CNS) penetration effectiveness (CPE) scores have been associated with better CNS human immunodeficiency virus (HIV) replication control, but the association between CPE and NCI remains controversial.

Methods: The Neurocognitive Assessment in the Metabolic and Aging Cohort (NAMACO) study is a subgroup of the Swiss HIV Cohort Study (SHCS) that invited patients aged ≥45 years enrolled in the SHCS and followed-up at NAMACO-affiliated centers in Switzerland to participate between May 2013 and November 2016.

Associations Between Antiretroviral Treatment and Avascular Bone Necrosis: The Swiss HIV Cohort Study.

Background: HIV-infected individuals have an increased risk of avascular bone necrosis (AVN). Antiretroviral therapy (ART) and particularly protease inhibitors (PI) have been implicated as a risk factor. We aimed to study the associations of ART with the occurrence of AVN among Swiss HIV Cohort Study participants (SHCS).

Privacy-preserving genomic testing in the clinic: a model using HIV treatment.

Purpose: The implementation of genomic-based medicine is hindered by unresolved questions regarding data privacy and delivery of interpreted results to health-care practitioners. We used DNA-based prediction of HIV-related outcomes as a model to explore critical issues in clinical genomics.

Methods: We genotyped 4,149 markers in HIV-positive individuals.

Reasons for late presentation to HIV care in Switzerland.

Introduction: Late presentation to HIV care leads to increased morbidity and mortality. We explored risk factors and reasons for late HIV testing and presentation to care in the nationally representative Swiss HIV Cohort Study (SHCS).

Methods: Adult patients enrolled in the SHCS between July 2009 and June 2012 were included.

Co-trimoxazole prophylaxis is associated with reduced risk of incident tuberculosis in participants in the Swiss HIV Cohort Study.

Co-trimoxazole reduces mortality in HIV-infected adults with tuberculosis (TB), and in vitro data suggest potential antimycobacterial activity of co-trimoxazole. We aimed to evaluate whether prophylaxis with co-trimoxazole is associated with a decreased risk of incident TB in Swiss HIV Cohort Study (SHCS) participants. We determined the incidence of TB per 1,000 person-years from January 1992 to December 2012.
