Abstract
Objective
During the pandemic, the SARS-CoV-2 infection with its different variants had determined high morbidity and mortality. As the clinical autopsies were reduced in our country, complete forensic autopsies had provided important valuable information regarding the pathological changes and pathophysiological mechanisms associated with SARS-CoV-2 infection. Our aim was to focus on different variants of SARS-CoV-2, trying to determine the contribution of SARS-CoV-2 infection to the lethal outcome and to establish the cause of death.
Methods
Complete autopsies were performed on cases confirmed by polymerase chain reaction for SARS-CoV-2 infection. All autopsies findings and the patient’s comorbidities were analyzed.
Results
Forty-nine cases were studied. Twenty were female (41%), and 29 were male (59%). The median age at death was 63 years (range 26-93 years), with an upward trend during the four variants of SARS-CoV-2. The age of the cases that died due to their comorbidities and were associated with SARS-Cov-2 infection was higher compared to the age of the cases that died due to SARS-CoV-2 infection. Two thirds of cases died at hospital, most of them with less than one week of hospitalization and one third of them were found dead at home. Most cases without significant health conditions died at home.
Conclusions
The immediate cause of death for many of our cases was of respiratory origin and most of them died of diffuse alveolar damage. The cases without evident comorbidities were less represented, that highlight the importance of multimorbidity in the development of critical illness.
