Abstract

INTRODUCTION: Diffuse interstitial lung disease associated with connective tissue diseases is the most common cause of interstitial pneumonia. The objective of the study was to describe the characteristics of patients with connective tissue disease who present interstitial lung disease.

MATERIALS AND METHODS: Descriptive and retrospective study in patients with interstitial lung disease associated with connective tissue diseases, with diagnoses established between 2015 and 2019, in the Caja de Seguro Social of Panama.

RESULTS: Thirty-eight cases were analyzed, most of them female (81.58%) with an average age of 57 years. Systemic sclerosis and rheumatoid arthritis were the most frequent collagen diseases, with 21.05% each. Dyspnea in 96.84% and cough in 60.53% were the most frequent respiratory symptoms. The most frequent antibodies were antinuclear antibodies in 34.21%, Anti-Ro, and rheumatoid factor in 18.42% of the cases. The tomographic pattern of nonspecific interstitial pneumonia was found in 34.21% of the cases, and the average value of carbon monoxide diffusion was 56% of the expected value. Steroids (50%) and azathioprine (38.24%) were the most used treatments.

CONCLUSION: The connective tissue diseases most associated with interstitial lung disease were systemic sclerosis and rheumatoid arthritis. Respiratory symptoms are nonspecific; carbon monoxide diffusion and a pattern of nonspecific interstitial pneumonia contribute to the diagnosis.
