Insights

This study of fatal COVID-19 cases found that older males with chronic diseases were most affected. Eosinophilopenia indicated a poor prognosis, and combined antimicrobial drugs showed limited benefit.

Area of Science:

  • Infectious Diseases
  • Epidemiology
  • Critical Care Medicine

Background:

  • Coronavirus disease (COVID-19) caused over 286,000 global deaths by May 2020.
  • Risk factors for COVID-19 mortality, such as advanced age and comorbidities, require precise definition.

Purpose of the Study:

  • To detail the clinical characteristics of 85 fatal COVID-19 cases.
  • To identify key clinical features and outcomes in a cohort of deceased COVID-19 patients.

Main Methods:

  • Retrospective analysis of medical records from 85 fatal COVID-19 cases (January 9–February 15, 2020).
  • Data collected included demographics, medical history, comorbidities, symptoms, laboratory findings, imaging, and treatments.

Main Results:

  • The median age of deceased patients was 65.8 years, with 72.9% being male.
  • Common symptoms included fever, shortness of breath, and fatigue. Hypertension and diabetes were prevalent comorbidities.
  • Eosinophil counts were very low in 81.2% of patients. Respiratory failure, shock, and acute respiratory distress syndrome were frequent complications.

Conclusions:

  • Fatal COVID-19 cases predominantly involved males over 50 with chronic noncommunicable diseases.
  • Multiple organ failure was the primary cause of death. Early shortness of breath may signal exacerbation, and eosinophilopenia suggests a poor prognosis.
  • Combination antimicrobial therapy did not significantly improve outcomes in this patient group.

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
