Although the pathophysiology underlying severe COVID19 remains poorly understood, accumulating data suggest that a lung-centric coagulopathy may play an important role. Elevated D-dimer levels which correlated inversely with overall survival were recently reported in Chinese cohort studies. Critically however, ethnicity has major effects on thrombotic risk, 3-4-fold lower risk compared to Caucasians and significantly higher African-Americans. In this study, we investigated Caucasian...

Rationale: Much is known about the acute infective process of severe respiratory syndrome coronavirus 2 (SARS-CoV-2), causative virus disease (COVID-19) pandemic. The marked inflammatory response and coagulopathic state in SARS-CoV-2 infection may promote pulmonary fibrosis. However, little incidence seriousness post–COVID-19 pathology. Objectives: To describe recovery self-reported health after at time outpatient attendance. Methods: Infection severity was graded into three groups: 1) not...

BackgroundPersistent fatigue, breathlessness, and reduced exercise tolerance have been reported following acute COVID‐19 infection. Although immuno‐thrombosis has implicated in pathogenesis, the biological mechanisms underpinning long COVID remain unknown. We hypothesized that pulmonary microvascular may be important this context.MethodsOne hundred fifty patients were reviewed at St James's Hospital Dublin between May September 2020 a median of 80.5 (range 44–155) days after initial...

Many practical clinical questions regarding the management of human immunodeficiency virus (HIV)–associated neurocognitive disorder (HAND) remain unanswered. We sought to identify and develop answers key in HAND management. Sixty-six specialists from 30 countries provided input into program, which was overseen by a steering committee. Fourteen were rated as being greatest importance. Answers drafted an expert group based on comprehensive literature review. Sixty-three experts convened...

Summary Endothelial cell (EC) activation plays a key role in the pathogenesis of pulmonary microvascular occlusion, which is hallmark severe coronavirus disease 2019 (COVID‐19). Consistent with EC activation, increased plasma von Willebrand factor antigen (VWF:Ag) levels have been reported COVID‐19. Importantly however, studies other microangiopathies shown that VWF propeptide (VWFpp) more sensitive and specific measure acute activation. In present study, we further investigated nature...

Summary Chronic hepatitis C virus ( HCV ) infection is a leading cause of liver related morbidity and mortality. In many countries, there lack comprehensive epidemiological data that are crucial in implementing disease control measures as new treatment options become available. Published literature, unpublished expert consensus were used to determine key parameters, including prevalence, viremia, genotype the number patients diagnosed treated. this study 15 viremic prevalence ranged from...

Background The long-term clinical and physiological consequences of COVID-19 infection remain unclear. While fatigue has emerged as a common symptom following infection, little is known about its links with autonomic dysfunction.

Methods We recruited 20 fatigued non-fatigued patients (median age 44.5 years, 36/40...

BackgroundConsistent with fulminant endothelial cell activation, elevated plasma von Willebrand factor (VWF) antigen levels have been reported in patients COVID‐19. The multimeric size and function of VWF are normally regulated through A Disintegrin And Metalloprotease ThrombSpondin Motif type 1 motif, member 13 (ADAMTS‐13)‐‐mediated proteolysis.ObjectivesThis study investigated the hypothesis that ADAMTS‐13 regulation multimer distribution may be impaired severe acute respiratory...

BackgroundProlonged recovery is common after acute SARS-CoV-2 infection; however, the pathophysiological mechanisms underpinning Long COVID syndrome remain unknown. VWF/ADAMTS-13 imbalance, dysregulated angiogenesis, and immunothrombosis are hallmarks of COVID-19. We hypothesized that imbalance persists in convalescence together with endothelial cell (EC) activation angiogenic disturbance. Additionally, we postulate ongoing immune dysfunction may be linked to sustained EC coagulation...
