Respiratory dysfunction in patients with Marfan syndrome

Area of Science:

• Genetics
• Pulmonology
• Connective Tissue Disorders

Background:

• Marfan syndrome (MS) is an autosomal dominant inherited disorder affecting connective tissue.
• It is characterized by high gene penetrance and variable expression, impacting multiple organ systems.
• Fibrillin, the protein encoded by the affected gene, is crucial for elastic fiber formation.

Purpose of the Study:

• To assess the frequency of factors influencing respiratory tract dysfunction in Marfan syndrome patients.
• To identify specific anthropometric and morphological indicators associated with respiratory abnormalities.

Main Methods:

• The study included 45 patients diagnosed with Marfan syndrome, aged 2 to 54 years.
• Clinical examinations and standardized anthropometric measurements (cephalometric, chest) were performed.
• Evaluated indices included head width/length, facial morphology, and chest flattening, compared to healthy population norms.

Main Results:

• Analysis revealed several factors contributing to pulmonary disease in Marfan syndrome.
• Chest deformities and specific morphological measurements were found to influence respiratory function.
• The study identified a correlation between MS-related physical characteristics and respiratory compromise.

Conclusions:

• Marfan syndrome patients exhibit a significant risk of respiratory abnormalities.
• Morphological and anthropometric factors, particularly chest deformities, play a key role in respiratory compromise.
• Early identification of these factors is crucial for managing pulmonary complications in Marfan syndrome.
