AI Article Synopsis
- - The study explores immune response changes in COVID-19 patients, focusing on leukocyte levels, eosinophil activity, and cytokine profiles during hospitalization.
- - Researchers collected serum samples and medical data within the first 10 days of infection, finding increased levels of certain cytokines but decreased eosinophil levels in COVID-19 patients compared to hospitalized controls.
- - The findings suggest a complex immune response in COVID-19, with low eosinophil activity and high cytokine levels, indicating the need for more research on immune biomarkers and treatment approaches.
Article Abstract
Background: The immune response dynamics in COVID-19 patients remain a subject of intense investigation due to their implications for disease severity and treatment outcomes. We examined changes in leukocyte levels, eosinophil activity, and cytokine profiles in patients hospitalized with COVID-19.
Methods: Serum samples were collected within the first 10 days of hospitalization/confirmed infection and analyzed for eosinophil granule proteins (EGP) and cytokines. Information from medical records including comorbidities, clinical symptoms, medications, and complete blood counts were collected at the time of admission, during hospitalization and at follow up approximately 3 months later.
Results: Serum levels of eotaxin, type 1 and type 2 cytokines, and alarmin cytokines were elevated in COVID-19 patients, highlighting the heightened immune response ( < 0.05). However, COVID-19 patients exhibited lower levels of eosinophils and eosinophil degranulation products compared to hospitalized controls ( < 0.05). Leukocyte counts increased consistently from admission to follow-up, indicative of recovery.
Conclusion: Attenuated eosinophil activity alongside elevated chemokine and cytokine levels during active infection, highlights the complex interplay of immune mediators in the pathogenesis COVID-19 and underscores the need for further investigation into immune biomarkers and treatment strategies.

New-onset refractory status epilepticus after SARS-CoV-2 infection: a review of literature.

Athanasios, Nafpliou 1 C, Gerakas 15344, Athens, Greece,
Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system, neurological symptoms were reported both during acute and post-acute COVID-19. Notably, patients with no history of epilepsy or other neurological conditions developed new-onset refractory status epilepticus (NORSE) weeks, months, or even up to a year following the viral infection. While NORSE is uncommon, it carries a high mortality rate and can result in permanent epilepsy.

Aim: To investigate histopathological changes in the lung tissue of long-COVID patients.
Methods: In this cross-sectional study, transbronchial lung biopsy was performed in long-COVID patients with persisting symptoms and radiological abnormalities. Histopathologic analyses were performed by using hematoxylin-eosin, Martius, Scarlet and Blue, Movat's, thyroid transcription factor 1, CD34, and CD68 staining.

Objective: Subacute thyroiditis (SAT) is a painful inflammatory disorder of the thyroid gland, which - after a phase of thyrotoxicosis - leads to transient, or less frequently permanent hypothyroidism. Apart from a strong association with specific HLA alleles, the causes are uncertain. Viral disease has been hypothesised as a trigger, with Enteroviruses, namely Echoviruses and Coxsackieviruses, showing a seasonal distribution that coincides with the incidence of SAT.

Objective: To describe the demographic/clinical characteristics, treatment patterns, and mortality among patients hospitalized with COVID-19 during Omicron predominance by immunocompromised and high-risk status.
Methods: Retrospective observational study of patients hospitalized with COVID-19 between January 1, 2022 and November 30, 2022, using data from the Optum de-identified Clinformatics® Data Mart Database. Patient demographic/clinical characteristics, treatments, mortality and costs, were assessed, during the emergence of BA.
