Abstract

The objective of this study was to characterize the clinical profile, laboratory findings, treatment strategies, and outcomes of patients hospitalized with COVID-19 at the Department and Clinic of Internal Medicine, Angiology and Physical Medicine in Bytom, Poland, during the period from December 2021 to March 2022. A total of 120 adult patients with confirmed SARS-CoV-2 infection were retrospectively analyzed. Data included demographic information, vaccination status, comorbidities, laboratory biomarkers (CRP, IL-6, D-dimer), treatment modalities (including antibiotics, corticosteroids, anticoagulants, antivirals, and immunomodulators), and in-hospital mortality. Statistical analysis was performed using ANOVA, with significance set at p 100 pg/mL. Older age, lack of vaccination, and comorbidities were major risk factors for severe COVID-19. High values of CRP, D-dimer, and IL-6 were consistent with a worse prognosis, aligning with international findings. Corticosteroids and anticoagulants were widely used and clinically justified, while the routine use of antibiotics such as ceftriaxone may not be supported by current evidence. These results underscore the importance of evidence-based treatment protocols and biomarker-guided risk stratification in managing hospitalized COVID-19 patients.
