Psychological burden of pediatric primary immunodeficiency

Primary immunodeficiency disorder (PID), being a chronic disorder, may increase the prevalence of psychopathologies, but there are few studies on the effect of disease-related factors on psychopathology in this population. The aim of this study was therefore to assess and compare three groups: children with PID who receive i.v. immunoglobulin treatment; children with juvenile idiopathic arthritis (JIA); and healthy controls with respect to their mental health status.

Forty-four children with PID, 32 children with JIA and 30 healthy controls, underwent psychiatric evaluation. The Childhood Depression Inventory and the screen for child anxiety-related emotional disorders questionnaire were completed by the participants. The child behavior checklist was completed by the mothers of the participants. In addition, disease-related factors were identified.

The frequency of mood disorders between the three groups differed. There was no difference between the PID and JIA groups with respect to the prevalence of mood disorders and other psychopathologies. The disease-related factors were associated with the frequency of mood disorder in PID patients.

The rate of psychopathology was similar in patients with PID and JIA and higher than the controls. Some of the disease-related factors were associated with the frequency of mood disorders in the PID patients.
