Idiopathic Pulmonary Fibrosis: Review of Current Knowledge

Area of Science:

• Pulmonology
• Pathology
• Radiology

Background:

• Idiopathic pulmonary fibrosis (IPF) is a severe, incurable lung disease characterized by irreversible fibrotic remodeling.
• Pathological lung remodeling damages the alveolo-capillary barrier, reducing gas diffusion and lung compliance.
• This leads to hypoxia, muscle weakness, and progressive respiratory insufficiency.

Purpose of the Study:

• To provide current information on IPF, focusing on functional consequences and clinical manifestations.
• To discuss potential molecular and cellular mechanisms involved in IPF development.
• To summarize current treatment options for IPF.

Main Methods:

• Review of existing literature on IPF.
• Discussion of molecular and cellular mechanisms.
• Analysis of morphological changes from lung biopsies and high-resolution computed tomography (HRCT).

Main Results:

• IPF involves irreversible lung fibrosis, impaired gas exchange, and reduced lung compliance.
• Triggers and pathomechanisms of fibrotic remodeling remain largely unknown.
• Pharmacological treatment can slow, but not reverse, IPF progression.

Conclusions:

• Early detection and multidisciplinary management in specialized centers are vital for slowing IPF progression.
• Treatment includes antifibrotic therapy, lifestyle management, and addressing comorbidities.
• Lung transplantation is an option for select IPF patients.
