Differences between sexes concerning COVID-19-related pneumonia

Area of Science:

• Medical research
• Infectious diseases
• Pulmonology

Background:

• Pneumonia is a leading cause of global morbidity and mortality.
• The COVID-19 pandemic frequently presented as pneumonia, raising significant public health concerns.
• Sex is recognized as a factor influencing pneumonia incidence and outcomes.

Purpose of the Study:

• To investigate sex-based disparities in clinical presentation, laboratory findings, and mortality among patients with COVID-19-related pneumonia.
• To identify factors associated with mortality in COVID-19 pneumonia, stratified by sex.

Main Methods:

• Retrospective, multicenter study involving 340 adult patients hospitalized with COVID-19 pneumonia.
• Data collected included clinical features, laboratory results, radiological findings, and in-hospital/30-day mortality.
• Comparative analysis of outcomes between male and female patient cohorts.

Main Results:

• Males were older and had higher rates of cardiovascular disorders, while females had higher rates of obesity.
• In-hospital and 30-day mortality rates were significantly higher in males than in females.
• Males exhibited longer intensive care unit (ICU) stays, though overall hospital stay duration was similar between sexes.

Conclusions:

• Male patients with COVID-19 pneumonia faced higher mortality and prolonged ICU stays compared to females.
• Pre-existing comorbidities in males may contribute to increased mortality.
• Potential protective genetic factors in females could explain their better outcomes.
