Abstract [en]

Background: Legg-Calve-Perthes disease (LCPD) is a disease in children leading to deformation of the femoral head and can be a promoter for early dysfunction of the hip and early osteoarthritis of the hip. The study of health-related quality of life, physical activity, and behavior patterns in patients with LCPD can reveal its consequences later in life and also contribute to a better understanding of the etiology of the disease.

Patients and Methods: We identified 145 patients with LCPD diagnosed and treated at Uppsala University Hospital between 1978 and 1995. A total of 116 patients answered questionnaires regarding health-related quality of life (EQ-5D-3L), physical activity [International Physical Activity Questionnaire (IPAQ)], and hyperactive/inattentive behavior pattern [ADHD self-reporting symptom checklist (ASRS v1.1)] by interview. Patients were asked to report on fractures or soft-tissue injuries that required medical care. Medical charts were reviewed to determine age at onset of LCPD and treatment received.

Results: Patients with LCPD had significantly lower EQ-5D-3L and EQ VAS scores than the Swedish general population in all age groups. A total of 28% of our patient group had ASRS scores indicating they are likely or highly likely to have an ADHD diagnosis. A lower EQ-5D-3L score was significantly correlated with a higher total ASRS v1.1 score (=-0.309**). Over 90% of our patient group was physically active on a moderate or high level, despite 52% reporting either some or severe problems with pain according to the EQ-5D-3L questionnaire. Patients with high ASRS v1.1 scores (>16) had a significantly higher incidence of soft-tissue injuries than those with lower ASRS v1.1 scores.

Conclusion: The consequence of LCPD in adulthood was expressed in a lower quality of life compared with the Swedish general population. Despite this, the patients in our study reported a higher level of physical activity than the general population. A tendency toward hyperactive behavior pattern and high physical activity level may be present even in childhood and could contribute to the etiology of LCPD.

Level of Evidence: A retrospective study, level II.

Abstract [en]

The overall aim of the thesis was to add some pieces to the etiological puzzle of LCPD with special focus on vascular origin and hyperactivity. Furthermore we wanted to evaluate some consequences of LCPD in adulthood.

Swedish registry data were used to identify a cohort of patients with the diagnosis of LCPD. This cohort was compared with a general population– based cohort without LCPD to assess the relative risk of cardiovascular diseases, blood or coagulation defects, injury, ADHD, depression and mortality.

In a clinical study we assessed health-related quality of life (EQ-5D-3L), physical activity level (IPAQ) and screened for ADHD (ASRSv1.1) in 116 patients with a history of LCPD who were diagnosed or treated in Uppsala University Hospital between 1978 and 1995.

The results confirmed our hypothesis: Patients with a history of LCPD had a 1.7-fold higher risk of cardiovascular diseases, and a 1.4-fold higher risk for blood or coagulation defects compared with gender- and age-matched individuals without LCPD. We found a 1.2-fold higher risk for injuries requiring hospital admission than in gender- and age-matched individuals without LCPD. The risk was more pronounced among females. Furthermore, we found a 1.5-fold higher risk for ADHD. Stratified analysis revealed a 2.1-fold higher risk for ADHD among females with LCPD than among females without LCPD. The risk for depression was 1.3-fold higher, and more pronounced among females with LCPD. Patients with LCPD had a slightly higher mortality risk with higher risk for death from suicide and cardiovascular causes.

Patients with a history of LCPD reported a lower health-related quality of life and were more physically active than the Swedish population norm. 28% of 116 patients were likely to have ADHD or had already been diagnosed with ADHD.

Both vascular and blood diseases could be present even in childhood and could, in combination with hyperactive behavior pattern and a high physical activity level, contribute to the etiology of LCPD. The lower health-related quality of life and higher risk for depression might reflect the mental burden of LCPD. Patients with LCPD have a higher mortality risk with higher risk for death from suicide and cardiovascular causes.
