Abstract

Background: Restrictive lung diseases (RLDs) encompass a broad spectrum of pulmonary conditions that impair lung expansion and reduce lung volume. These diseases can be caused by various factors including fibrosis, neuromuscular disorders, and thoracic deformities. The pathophysiology of RLDs typically involves the alteration of lung architecture, resulting in impaired gas exchange and decreased respiratory function. The understanding of these diseases has evolved through advances in clinical guidelines and diagnostic methods, particularly for conditions such as idiopathic pulmonary fibrosis (IPF), sarcoidosis, and interstitial lung diseases (ILDs). Methods: A comprehensive review of the current literature was conducted, including data from clinical guidelines, peer-reviewed journals, and recent studies on the pathophysiology, diagnosis, and management of restrictive lung diseases. Emphasis was placed on studies related to the pathogenesis of interstitial lung disease, the impact of genetic factors, and advancements in diagnostic techniques such as spirometry and high-resolution CT imaging. Additionally, guidelines from major respiratory societies such as the American Thoracic Society (ATS) and European Respiratory Society (ERS) were analyzed. Results: The review highlighted the significant advances in understanding restrictive lung diseases, particularly in the context of idiopathic pulmonary fibrosis and other forms of interstitial lung disease. Key findings include the role of genetic predisposition in IPF, the importance of early diagnosis, and the integration of non-invasive diagnostic tools such as high-resolution CT scans. Treatment modalities for RLDs have expanded with new pharmacological agents, including antifibrotic therapies for IPF, as well as advancements in lung transplantation for patients with end-stage disease. Furthermore, bariatric surgery has been identified as a potential therapeutic option in patients with interstitial lung disease and comorbid obesity. Conclusion: Restrictive lung diseases remain a challenging group of conditions with complex pathophysiological mechanisms. However, recent advancements in genetic research, diagnostic imaging, and treatment strategies offer new hope for improving patient outcomes. The continued development of precision medicine, including targeted therapies and individualized treatment plans, is expected to revolutionize the management of RLDs. Further research is needed to refine diagnostic criteria, explore novel therapeutic options, and improve long-term management strategies for these debilitating conditions.
