Assessment of Disease Burden Among Japanese Patients With Pulmonary Sarcoidosis: A Questionnaire-Based Study

These findings quantitatively demonstrate the burden of systemic symptoms, particularly fatigue and symptoms associated with SFN, in Japanese patients with pulmonary sarcoidosis, with the present study being the first to evaluate KSQ scores in Japan. Even though this study could not establish causality due to its cross-sectional nature, the results underscore the importance of regularly monitoring and managing fatigue and symptoms associated with SFN in patients undergoing treatment with OCS. Such insights may support clinical decision-making and could contribute to optimizing management while minimizing HRQoL impairment.
