Fatigue in severe pediatric asthma patients: Results of the PANDA study

Le résumé fourni par la source

Abstract Background Fatigue is a commonly reported clinical symptom, yet research on fatigue in children with severe asthma is missing. We aimed to explore the extent of fatigue in severe pediatric asthma and identify associated factors. Method This study was conducted within the Pediatric Asthma Non‐Invasive Diagnostic Approaches (PANDA), an observational cohort of 6‐ to 17‐year‐old Dutch children with severe asthma. The Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL™‐MFS) was used to measure self‐reported fatigue. Fatigue levels were compared with a general pediatric Dutch population using linear regression, and quantifying the prevalence of “fatigued” (−2 < Standard deviations [SD] ≤ −1) and “severely fatigued” (SD ≤ −2) children. Secondly, we performed linear regression analyses to explore whether fatigue levels were independently associated with asthma attacks, comorbidities, medication, pulmonary function, symptom control, and asthma‐related quality of life (QoL). Results Severe pediatric asthma patients ( n = 78, mean age 11.8 ± 3.1 years) reported significantly more fatigue than Dutch peers ( n = 328, mean age 11.8 ± 3.2 years) mean difference in z ‐score: −0.68; 95%CI −0.96, −0.40. In the severe asthma group, 28.2% scored as “fatigued” and 15.4% as “severely fatigued,” compared with 14.0% and 3.4% in the general population. In pediatric asthma patients, asthma‐related QoL ( β = 0.77, p < .01, Δ R 2 = .43), symptom control ( β = 0.56, p < .01, Δ R 2 = .24) and a dysfunctional breathing pattern ( β = −0.36, p < .01, Δ R 2 = .12) were most strongly associated with fatigue scores. Conclusion Fatigue is a common symptom in children with severe asthma and is associated with multiple clinical factors and patient‐reported outcomes. It should be considered as an important treatment target.
