Abstract The bacteriophage behavior of SARS‐CoV‐2 during the acute and post‐COVID‐19 phases appears to be an important factor in development disease. early use antibiotics seems crucial inhibit disease progression—to prevent viral replication gut microbiome, control toxicological production from human microbiome. To study impact specific on recovery COVID‐19 long COVID (LC) taking into account: vaccination status, comorbidities, wave, time initiation antibiotic therapy concomitant corticosteroids nonsteroidal anti‐inflammatory drugs (NSAIDs). A total 211 patients were included study: which 59 vaccinated with mRNA vaccines against while 152 unvaccinated. Patients enrolled three waves: September 2020 October 2022, corresponding emergence pre‐Delta, Delta, Omicron variants virus. criteria for enrolling were: oropharyngeal swab positivity or fecal findings; moderate symptoms intake; measurement blood oxygen saturation period illness. combinations, such as amoxicillin clavulanic acid (875 + 125 mg tablets, every 12 h) plus rifaximin (400 tablets h), first choice, suggested previous data, azithromycin (500 24 above, allows healthcare professionals focus microbiome its implications patient care. primary outcome measured this was estimated average treatment effect, quantified difference mean between receiving those not at 3 9 days after start treatment. In analysis, both unvaccinated groups had a median illness duration 7 (interquartile range [IQR] 6–9 each; crude hazard ratio [HR] = 0.94, p 0.700). pre‐Delta Delta waves 8 (IQR 7–10 days), it shorter, 6.5 days, 6–8 days; HR 1.71, < 0.001). These results confirmed by multivariate analysis. comorbidities significantly longer duration: days) compared without (crude 0.75, 0.038), but result analysis statistical significance lost. Early resulted shorter 4.74, Concomitant NSAIDs did reduce prolonged ( 0.041). subgroup 42 3–6 (median IQR 8–10 others 0.542, 0.001), also adjusted HR. study, statistically significant reduction observed among who received played role maintaining higher levels saturation. addition, is worth noting that number phase develop LC.

A severe consequence of SARS-CoV-2 infection that manifests as systemic inflammation and multi-organ involvement is called Multisystem Inflammatory Syndrome in Children (MIS-C). This review examines the possible relationship between gut barrier integrity, microbiome, dysregulation interleukin 6 (IL-6) signaling, MIS-C. Clinical biochemical features MIS-C are comparable to those other hyper-inflammatory syndromes, suggesting a dysregulated immune response. One explanation for seen patients SARS-CoV-2-induced IL-6 signaling pathway. In addition, new data suggest reciprocal link integrity IL-6. exhibits bacteriophage-like behavior, highlighting role bacteria reservoir virus emphasizing importance understanding bacteriophagic mechanism fecal–oral transmission. The increased translocation viral products bacterial toxins may result from disrupting intestinal cause inflammation. On hand, can weaken barrier, which feeds back into loop immunological dysregulation. context MIS-C, interaction infection, IL-6, shed light on etiology disease guide treatment options. Since children with dysbiosis be more susceptible it critical reinforce their microbiome through probiotics supplementation, plant-fiber-rich diets (prebiotics). Early antibiotic use zonulin antagonists should also considered.

COVID-19 has caused millions of deaths globally; however, the characterization molecular biomarkers severe disease remains great scientific importance. The aim this study was to capture transcriptional differences whole blood gene expression between patients with mild and disease, using Next Generation Sequencing technologies, on admission after 7 days. genes which were differentially expressed in compared used for Gene Ontology (GO) enrichment analysis. data estimate cell abundance 22 immune types via digital cytometry. GO terms related response molecules bacterial origin, such as intestine-derived lipopolysaccharide (LPS), enriched, among other dysregulated pathways, are well described paramount mechanisms manifestations COVID-19. neutrophil population increased whereas monocyte, CD8+ T cell, activated Natural Killer (NK) populations depleted. These dynamics also indicative intestinal translocation. This elucidates basis highlights translocation a potential driver disease.
