Summary
This review details how SARS-CoV-2 affects the liver, including in those with existing liver conditions. It also examines COVID-19 vaccination
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impacts organs beyond the respiratory system, notably the liver.
- Understanding the liver's response to SARS-CoV-2 is crucial for managing coronavirus disease 19 (COVID-19) patients.
Purpose of the Study:
- To document the effects of SARS-CoV-2 on the liver in healthy individuals and those with pre-existing liver disease.
- To examine the relationship between COVID-19 vaccination and liver injury.
- To explore the mechanisms of SARS-CoV-2-associated liver injury and its long-term consequences.
Main Methods:
- Comprehensive literature review of studies on SARS-CoV-2 and liver involvement.
- Analysis of clinical data and research findings concerning COVID-19's impact on liver health.
- Exploration of immunological and pathological mechanisms underlying liver injury.
Main Results:
- SARS-CoV-2 infection can cause liver injury in both healthy individuals and those with underlying liver conditions.
- The relationship between COVID-19 vaccination and liver injury is complex and requires further investigation.
- Specific mechanisms contribute to SARS-CoV-2-induced liver damage, with potential for long-term sequelae.
Conclusions:
- SARS-CoV-2 poses a significant threat to liver health, necessitating careful monitoring in all patients.
- Further research is needed to fully understand the impact of COVID-19 vaccination on liver function.
- Long-term follow-up is essential for patients affected by COVID-19, particularly those with pre-existing liver disease.

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

01:30Liver Physiology
585
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

01:17Gross Anatomy of the Liver
474
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

01:20COPD: Pathogenesis and Clinical Features
302
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...
