Popis: Pain, fatigue and depression in chronic inflammatory demyelinating polyneuropathy (CIDP) are often underestimated, as the focus lies on sensorimotor dysfunction and gait instability. The aim of this study was to investigate their prevalence, characteristics and contribution to disability in a prospective cohort of 84 patients with CIDP.Pain, fatigue, depression and quality of life were measured using the Pain Detect Questionnaire, Krupp's Fatigue Severity Scale, Beck Depression Inventory II and the German Short-Form 36 Health Survey. Sensorimotor deficits and disability were assessed using the Inflammatory Neuropathy Cause and Treatment overall disability score, the Rasch-built Overall Disability Scale, the Medical Research Council sum score and the Inflammatory Neuropathy Cause and Treatment sensory sum score. The interrelation between the five factors was assessed using analysis of variance and linear regression analysis.Pain was reported in 62%, mostly of moderate and severe intensity, whereas pain characteristics indicated neuropathic pain (NP) in 29%. Sensory dysfunction was stronger in NP patients compared to pain-free patients (p = 0.001). Pain of any type, especially NP, was associated with more pronounced fatigue symptoms (p = 0.010). Depressive symptoms were more frequent in patients with pain compared to the pain-free patients (61% vs. 33%, p = 0.02) and were more severe and frequent in NP than in non-NP patients (p = 0.005). Patients with pain had a worse physical quality of life than pain-free patients (p = 0.001).Pain, depression and fatigue are relevant disability factors in CIDP affecting quality of life. Sensory dysfunction is associated with NP. Therefore, evaluation of CIDP-related disability should include pain and sensory function for adequate monitoring of therapeutic interventions.
