COVID-19 with Different Severities: A Multicenter Study of Clinical Features
American Journal of Respiratory and Critical Care Medicine
|April 11, 2020
Summary
This study compared COVID-19 patient characteristics across three Chinese cities. Older age and severe illness were linked to higher mortality, with specific treatments varying by disease severity.
Area of Science:
- Infectious Diseases
- Public Health
- Internal Medicine
Background:
- The COVID-19 pandemic presents a significant global health challenge.
- Understanding clinical variations in COVID-19 is crucial for effective management.
Purpose of the Study:
- To compare clinical characteristics, laboratory findings, CT imaging, and treatments of COVID-19 patients.
- To identify factors associated with disease severity and mortality.
Main Methods:
- Retrospective analysis of 476 COVID-19 patients from Wuhan, Shanghai, and Anhui.
- Patients categorized by age and disease severity (moderate, severe, critical).
- Data collected on comorbidities, medications, imaging findings, and treatment interventions.
Main Results:
- Higher comorbidity incidence in severe and critical groups (67.1%).
- Angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker use differed by severity.
- Multiple lung lobe involvement and pleural effusion were more common in critical cases.
- Patients >75 years old had significantly lower survival rates.
Conclusions:
- Multiple organ dysfunction and immune impairment characterize severe/critical COVID-19.
- Age (≥75 years) is a significant risk factor for mortality.
- Disease severity correlates with lung involvement, pleural effusion, and specific medication use.

01:20COPD: Pathogenesis and Clinical Features
1.7K
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...

245
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

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...
