SARS-CoV-2 infection. Descriptive analysis of a selected case series

Area of Science:

• Infectious Diseases
• Pathophysiology
• Clinical Medicine

Background:

• The COVID-19 pandemic, declared in March 2020, has seen extensive reporting on clinical, analytical, and radiological findings.
• However, detailed accounts of differing patient evolutions within the same local outbreak remain scarce.

Purpose of the Study:

• To report and analyze the distinct clinical, radiological, and analytical evolution of six selected COVID-19 patients.
• To investigate the varied outcomes and potential underlying pathophysiological differences in patients from a single local outbreak.

Main Methods:

• Case study reporting on six patients with epidemiological links.
• Monitoring of clinical symptoms, laboratory inflammatory markers (e.g., D-dimer, IL-6, ferritin, lymphocytes), and radiological findings.
• Comparative analysis of disease progression and outcomes.

Main Results:

• Initial symptoms were similar across patients, but clinical evolution varied significantly.
• Elevated inflammation markers correlated with moderate to severe disease courses.
• Lung alterations were prominent, alongside common neurological/neuropsychiatric findings.
• Outcomes ranged from moderate symptoms in two patients to fatality in the two most severely affected.

Conclusions:

• Significant heterogeneity exists in COVID-19 patient evolution and outcomes, even within the same local outbreak.
• Inflammation markers serve as indicators for disease severity and progression.
• Beyond respiratory involvement, other pathophysiological aspects warrant further investigation to understand diverse COVID-19 trajectories.
