Health-related quality of life in patients with Camurati-Engelmann disease: A case series study

Camurati-Engelmann disease (CED) is an extremely rare autosomal dominant bone dysplasia characterized by hyperostosis of the long bones and, in severe cases, of the skull and axial skeleton. This study aims to analyze the impact on quality of life in a non-selected group of CED patients.

This monocentric case series study included 15 patients who completed a survey that collected demographic characteristics, disease-related information and a validated SF-12 questionnaire to assess quality of life. Physical (PCS-12) and Mental (MCS-12) Component Summary scores were compared with the mean SF-12 scores of the U.S. reference population.

Patients had significantly lower PCS-12 score [29.8 (7.5)] compared to the reference population [50.0 (10.0)] (p<0.0001). However, there were no differences in the MCS-12 score [48.8 (11.23) vs 50.0 (10.0)]. The most reported symptoms were fatigue (100%), pain in the limbs (93.3%) and muscle pain (86.7%).

CED patients have significantly lower physical quality of life than the general population, due to the high prevalence of physically limiting problems. However, mental health appears unaffected.
