Background
As it is less known about the prevalence and characteristics of pain in the patients with interstitial lung disease (ILD), this paper aims at determining the characteristics of the pain in the patients with ILD.
Methods
Subjects with ILD and health controls with the matched ages and genders completed Short Form McGill Pain Questionnaire (SF-MPQ) and part of the Brief Pain Inventory (BPI) Short Form to elicit the characteristics of the pain. The patients with ILD were also assessed through Pulmonary Function Test, Six Minutes Walking Test (6MWT), modified Medical Research Council Dyspnea Scale (mMRC) for state of the illness and measured health-related quality of life (HRQoL) by Short Form-36 (SF-36) and psychological associations by Hospital Anxiety and Depression Scale (HADS).
Results
A total of 63 subjects with ILD and 63 healthy controls (HC) were recruited in our study. The prevalence of the pain was 61.9% in ILD versus 25.3% in HC (P = 0.005) and the median score of the pain rank index (PRI) in ILD was higher than that in HC (P = 0.014). Chest (46.1%) accounted for the highest of overall pain locations in subjects with ILD. Associated clinical factors for pain intensity in the patients with ILD included exposure history of risk factors of ILD, with a longer distance of 6MWD (≥ 250 m), and a higher mMRC score (2–4). The patients with ILD and pain are more likely to suffer impaired HRQoL (P = 0.0014) and psychological problems (P = 0.0017, P = 0.044).
Conclusion
The pain is common in those with ILD and the pain intensity is associated with exposure history, 6MWD, and mMRC score. The patients with ILD and pain were possibly to suffer depression, anxiety, and impaired HRQoL.
