Heritable Connective Tissue Disorders in Childhood: Increased Fatigue, Pain, Disability and Decreased General Health
Heritable Connective Tissue Disorders (HCTD) show an overlap in the physical features that can evolve in childhood. It is unclear to what extent children with HCTD experience burden of disease. This study aims to quantify fatigue, pain, disability and general health with standardized validated questionnaires. Methods. This observational, multicenter study included 107 children, aged 4 18 years, with Marfan syndrome (MFS) 58% Loeys Dietz syndrome (LDS) 7% Ehlers Danlos syndromes (EDS) 8% and hypermobile Ehlers Danlos syndrome (hEDS) 27% The assessments included PROMIS Fatigue Parent Proxy and Pediatric self report, pain and general health Visual Analogue Scales (VAS) and a Childhood Health Assessment Questionnaire (CHAQ) Results. Compared to normative data, the total HCTD group showed significantly higher parent rated fatigue T scores (M 53 (SD 12) p 0.004, d 0.3) pain VAS scores (M 2.8 (SD 3.1) p 0.001, d 1.27) general health VAS scores (M 2.5 (SD 1.8) p 0.001, d 2.04) and CHAQ disability index scores (M 0.9 (SD 0.7) p 0.001, d 1.23) HCTD subgroups showed similar results. The most adverse sequels were reported in children with hEDS, whereas the least were reported in those with MFS. Disability showed significant relationships with fatigue (p 0.001, rs 0.68) pain (p 0.001, rs 0.64) and general health (p 0.001, rs 0.59) Conclusions. Compared to normative data, children and adolescents with HCTD reported increased fatigue, pain, disability and decreased general health, with most differences translating into very large sized effects. This new knowledge calls for systematic monitoring with standardized validated questionnaires, physical assessments and tailored interventions in clinical care.
