Coronavirus Disease 2019 (COVID-19), caused by the novel Severe Acute Respiratory Syndrome 2 (SARS-CoV-2), has affected over 30 million globally to date. Although high rates of venous thromboembolism and evidence COVID-19-induced endothelial dysfunction have been reported, precise aetiology increased thrombotic risk associated with COVID-19 infection remains be fully elucidated. Therefore, we assessed clinical platelet parameters circulating activity in patients severe nonsevere COVID-19. An...
We aimed to describe the clinical presentation of individuals presenting with prolonged recovery from coronavirus disease 2019 (COVID-19), known as long COVID.This was an analysis within a multicenter, prospective cohort study confirmed diagnosis COVID-19 and persistent symptoms >4 weeks onset acute symptoms. performed multiple correspondence (MCA) on most common self-reported hierarchical clustering results MCA identify symptom clusters.Two hundred thirty-three were included in analysis;...
Abstract Background The European AIDS Clinical Society (EACS) Guidelines were revised in 2021 for the 17th time with updates on all aspects of HIV care. Key points update Version 11.0 recommend six first‐line treatment options antiretroviral (ART)‐naïve adults: tenofovir‐based backbone plus an unboosted integrase inhibitor or doravirine; abacavir/lamivudine dolutegravir; dual therapy lamivudine emtricitabine dolutegravir. Recommendations preferred and alternative combinations from birth to...
Current or recent use of abacavir for treating human immunodeficiency virus type 1 (HIV-1) infection has been associated with increased rates myocardial infarction (MI). Given the role platelet aggregation in thrombus formation MI and reversible nature association, we hypothesized that patients treated would have reactivity.In a prospective study adult HIV-infected patients, determined associations between antiretrovirals (ARVs), particular nucleoside reverse transcriptase inhibitor...
Low bone mineral density (BMD) is common in HIV-positive patients, although the role played by HIV infection versus sociodemographic and metabolic factors remains unclear.Understanding Pathology of Bone Disease HIV-infected individuals (HIV UPBEAT) a prospective cohort study, enrolled HIV-negative participants from similar demographic backgrounds. Dual X-ray absorptiometry at femoral neck, total hip lumbar spine blood tests were performed. Associations between BMD interest assessed using...
Background: Whilst reporting improved renal and bone safety profiles, studies have noted changes in lipid profiles among people living with HIV (PLWH) receiving antiretroviral therapy (ART) switching away from tenofovir disoproxil fumarate (TDF) to alafenamide (TAF). We aimed characterize lipids observed after TAF-containing ART a real-world setting. Methods: A prospective study on PLWH enrolled the UCD-ID Cohort who switched ART. Routine laboratory data [including (total cholesterol (TC),...
BackgroundFew studies to date have explored the health-related quality of life (HRQoL) in patients with long COVID.MethodsThe Anticipate Study is a prospective single-centre observational cohort study. Hospitalised and nonhospitalised were seen at dedicated post-COVID clinic 2-4 month (Timepoint 1) 7-14 follow-up 2). The main objectives this study are assess longitudinal impact COVID-19 using 12-item Short Form Survey (SF-12) score, tool, identify predictors developing post–COVID-19 syndrome...
SARS-CoV-2 neutralising antibodies provide protection against COVID-19. Evidence from early vaccine trials suggested binding antibody thresholds could serve as surrogate markers of capacity, but whether these predict sufficient capacity variants concern (VOCs), and this is impacted by or infection history remains unclear. Here we analyse individuals recovered from, vaccinated with hybrid immunity SARS-CoV-2. An NT50 ≥ 100 IU confers in trials, however, VOC induce a reduction NT50, use 1000...
Abstract Background The global mpox outbreak which started in May 2022 was caused by a novel clade IIb variant of the virus (MPXV). It differed from traditional Western and Central Africa disease transmission patterns clinical presentation. Methods To address need for detailed virologic data, we conducted an observational cohort study (MOSAIC) during 2022-July 2023 individuals with confirmed MPXV infection enrolled six European Countries. Case-management decisions were left to attending...
Abstract Background Inflammation and innate immune activation are associated with chronic HIV infection, despite effective treatment. Although gut microbiota alterations linked to systemic inflammation, the relationships between microbiome, inflammation remain unclear. Methods The UPBEAT-CAD sub-study, examining cardiovascular disease (CVD) risk in HIV, enrolled participants matched on status traditional CVD factors. Subclinical was assessed using coronary computed tomography angiography...
Abstract Patient and public involvement engagement (PPIE) in health care research has been advocated to ensure that the is relevant, acceptable beneficial communities it serves. However, there remains a significant gap projects incorporating PPIE among transgender communities, particularly from global South. In this narrative summary authors describe methodology of through novel collaboration with community members for design development bilingual culturally sensitive educational...
Cardiovascular disease and myocardial infarction are of increasing concern in HIV-infected populations. Although platelets mediate arterial thrombosis, central to infarction, data on platelet function HIV infection lacking. We hypothesized that patients would have altered reactivity.A case-control study reactivity 20 (HIVpos) age sex-matched HIV-negative (HIVneg) individuals.Time-dependent aggregation was measured response concentrations agonists: epinephrine, collagen, thrombin...
In virologically suppressed, antiretroviral-treated patients, the effect of switching to tenofovir (TDF) on bone biomarkers compared patients remaining stable antiretroviral therapy is unknown.We examined (osteocalcin [OC], procollagen type 1 amino-terminal propeptide, and C-terminal cross-linking telopeptide collagen) mineral density (BMD) over 48 weeks in suppressed (HIV RNA < 50 copies/ml) randomized switch TDF/emtricitabine (FTC) or remain first-line zidovudine (AZT)/lamivudine (3TC)....
