Asthma: Pathogenesis and Management

1.3K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Cystic Fibrosis: Pathogenesis

743
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pulmonary Hypertension: Classification and Pathogenesis

602
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

COPD: Pathogenesis and Clinical Features

1.8K
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...

Tumor Progression02:07

Tumor Progression

7.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Summary

Chronic thromboembolic pulmonary hypertension (CTEPH) may arise from factors beyond pulmonary thromboembolism (PTE). Understanding CTEPH pathogenesis is crucial for developing new treatments and preventive strategies.

Area of Science:

  • Cardiology
  • Pulmonary Medicine
  • Pathophysiology

Background:

  • Chronic thromboembolic pulmonary hypertension (CTEPH) is a known complication of pulmonary thromboembolism (PTE).
  • Many CTEPH patients lack a history of symptomatic PTE, indicating other causative factors.
  • Current understanding of CTEPH pathophysiology is limited, challenging treatment and prognosis.

Purpose of the Study:

  • To review current research on the pathogenesis of CTEPH.
  • To identify risk factors and underlying mechanisms contributing to CTEPH development.
  • To inform the development of novel therapeutic and preventive strategies for CTEPH.

Main Methods:

  • Literature review of studies on CTEPH pathogenesis.
  • Analysis of risk factors including medical history and genetic susceptibility.
  • Examination of mechanisms such as coagulation, inflammation, angiogenesis, thrombosis, and vascular remodeling.

Main Results:

  • CTEPH pathogenesis involves multiple factors beyond PTE.
  • Key contributing factors include abnormal coagulation and fibrinolysis, inflammation, genetic predisposition, angiogenesis, in situ thrombosis, and vascular remodeling.
  • Understanding these diverse pathways is essential for advancing CTEPH management.

Conclusions:

  • CTEPH is a complex condition with multifactorial origins.
  • Further research into CTEPH pathogenesis is vital for improving patient outcomes.
  • Identifying novel therapeutic targets and preventive measures requires a comprehensive understanding of its underlying mechanisms.
