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

Area of Science:

• Infectious Diseases
• Virology
• 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 the varied clinical evolution among patients from the same local outbreak remain scarce.

Purpose of the Study:

• To report and analyze the distinct clinical, radiological, and analytical evolution of six patients who were epidemiological close contacts within a single COVID-19 outbreak.
• To highlight the heterogeneity in disease progression and outcomes despite shared exposure.

Main Methods:

• A retrospective case series approach was employed, focusing on six patients with confirmed COVID-19.
• Clinical, radiological, and laboratory data were collected and analyzed to track disease progression.
• Patient selection was based on epidemiological linkage and observed differences in clinical outcomes.

Main Results:

• Initial symptoms in the first week were similar across all patients.
• Clinical severity correlated with inflammatory markers such as D-dimer, IL-6, ferritin, and lymphocyte counts.
• While lung alterations were prominent, neurological/neuropsychiatric findings were also common.
• Two patients experienced moderate symptoms, whereas two severely affected patients unfortunately died.

Conclusions:

• The study underscores the need to further elucidate the diverse evolutionary pathways and outcomes of COVID-19.
• Significant differences in clinical, laboratory, and radiological features were observed among these six patients from the same outbreak.
• The findings prompt a discussion on the pathophysiology of COVID-19 beyond the commonly described respiratory system involvement.
