Short-Term Effects of a Multimodal 3-Week Inpatient Pulmonary Rehabilitation Programme for Patients with Sarcoidosis: The ProKaSaRe Study

BACKGROUND: Real-world data on the effects of a multicomponent pulmonary rehabilitation (PR) for patients with sarcoidosis are scarce. OBJECTIVE: To describe characteristics of patients with sarcoidosis referred for a 3-week inpatient PR, to assess the effects of PR on their quality of life (QoL) and clinical outcomes, and to investigate whether there are specific subgroups who particularly benefit from PR. METHODS: Using a prospective multicentre study design, data regarding 6-min walking distance (6MWD), QoL (Saint George's Respiratory Questionnaire, SGRQ), and the secondary outcomes of dyspnoea and psychological burden (fatigue, anxiety, and depression) were collected. RESULTS: We included 296 patients in the study (average age 49.1 +/- 9.7 years, 47% female, average vital capacity 3.5 +/- 1.0 L [87.0 +/- 20.6 predicted]). The 6MWD improved by the end of the rehabilitation by 39.8 m on average (p < 0.0001; standardised response mean, SRM = 0.61), SGRQ showed significant improvements in all 3 domains, and the total score (p < 0.001) improved by 5.69-8.28 points (SRM 0.46-0.62). For the secondary outcomes, significant improvement (p < 0.001) was seen for all measured parameters, e.g., dyspnoea (modified Medical Research Council Scale, mMRC), fatigue (Fatigue Assessment Scale [FAS]; SRM = -0.71), anxiety and depression (Hospital Anxiety and Depression Scale [HADS]; SRM -0.58/-0.38), and generic QoL (measured by the SF-36 scales of physical and mental health; SRM 0.31/0.55). CONCLUSIONS: Our results provide the first documented evidence that PR is a promising complementary therapy option for sarcoidosis patients who remain subjectively symptomatic despite optimised outpatient medical treatment.
