Is there an association between human herpesviruses (HHVs) reactivation and Long COVID? We analyzed HHV DNA shedding in saliva and found that HHV-6 correlates with Long COVID severity. Claire Laxton, @S_Tabachnikova, Lily Cooke, Kexin Wang et al. medrxiv.org/content/10.648… (1/)



Comprehensive Immunophenotyping of Monocytes and Dendritic Cells Suggests Distinct Pathophysiology in Chronic Fatigue Syndrome and Long COVID 🚨Interesting new decisive data confirming divergence: ME/CFS and Long COVID are NOT the same disease! ➡️This international study used multiparameter flow cytometry on peripheral blood mononuclear cells to compare immune profiles in ME/CFS (n=103), Long COVID (n=63), and healthy controls (n=41). It targeted monocytes (M1/M2-like), dendritic cells (DCs), and T-cell subsets to uncover disease-specific signatures, ➡️Long COVID Profile: - Marked by increased M2-like monocyte polarization, elevated CD80 (costimulatory marker) across monocyte subsets, DC expansion, and paradoxically reduced activation markers (e.g., CD69+CD38), - Indicates persistent immune activation combined with exhaustion features, ➡️ME/CFS Profile: - Characterized by reduced costimulatory molecule expression (e.g., lower CD80 on DCs/monocytes), impaired CCR7 expression (disrupting immune cell trafficking), and less coordinated activation patterns, consistent with immune suppression, ➡️Additional Analyses: - Correlation networks showed more extensive, integrated immune interactions in Long COVID vs. fragmented patterns in ME/CFS, - Principal component analysis (PCA) and PLS-DA revealed distinct immunophenotypic clusters, enabling moderate discrimination between the two conditions (AUC ~0.76 in moderate cases), ➡️Implications: - Age-adjusted statistics confirmed differences, - Findings point to divergent post-infectious immunopathologies rather than a shared syndrome, ➡️Conclusion: - ME/CFS and Long COVID are not the same disease, - They drive opposite immune failures, one of chronic hyper-activation tipping into exhaustion, the other of outright suppression and trafficking collapse, - Treating them as interchangeable is scientifically indefensible and clinically harmful, - Distinct biomarkers now exist: →Separate pathophysiology demands separate diagnostics and therapies! #MECFS #LongCOVID #AvoidSars2 #AvoidReinfections mdpi.com/1422-0067/27/1…







Imagine having all Elisa, Annalisa, Emma, Giorgia and Laura Pausini in a single country. Such voices. #rilive


I believe in socializing basically 24/7. This has made me more money than anything else. High energy levels and constant social interaction.
