Severe asthma may indicate rare autoinflammatory diseases. Genetic testing identified conditions like familial Mediterranean fever in five patients, aiding diagnosis of complex respiratory symptoms.
Area of Science:
- Immunology
- Genetics
- Pulmonology
Background:
- Respiratory conditions, particularly severe asthma, are rarely linked to autoinflammatory diseases.
- This study focuses on five patients with uncontrolled respiratory symptoms initially managed for severe asthma.
Purpose of the Study:
- To investigate the association between severe asthma and rare autoinflammatory conditions.
- To highlight the diagnostic utility of genetic molecular analysis in complex respiratory cases.
Main Methods:
- A case series of five patients with severe asthma and unexplained symptoms.
- Genetic mutation analysis for autoinflammatory syndromes (e.g., familial Mediterranean fever, Yao syndrome).
- Exclusion of other potential causes like parasitic infections, fungal infections, and eosinophilic disorders.
Main Results:
- Five patients with severe asthma were diagnosed with rare autoinflammatory conditions through genetic testing.
- Identified mutations were associated with familial Mediterranean fever, Yao syndrome, Cryopyrin-associated periodic syndrome, and Majeed syndrome.
- These diagnoses helped explain the patients' complex clinical manifestations.
Conclusions:
- Diagnosing autoinflammatory diseases in patients presenting with respiratory conditions is challenging.
- Genetic molecular testing is crucial for identifying underlying autoinflammatory disorders in undifferentiated patients.
- Further research is needed on the role of inflammasome activation in asthma and eosinophilia.

Asthma: Pathogenesis and Management
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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
