A preliminary assessment of behavioral problems in children with mastocytosis.

OBJECTIVE

The objectives of this study were to 1) review mastocytosis in terms of the behavioral pathology in adults, and 2) to assess a group of pediatric patients with mastocytosis to determine if similar behavioral pathology is evident.

METHOD: Twelve children ages two to eleven referred to the NIH, a tertiary referral center for mastocytosis, were studied. Questionnaires were mailed for assessment of the child's behavior: parents completed the Childhood Behavior Checklist (CBCL) and children four years of age or more were evaluated by their teachers via the Child Behavior Checklist-Teacher Report form. Scores were compared to published normative data and to published data from other medically ill pediatric groups. Pathology was defined as present if the child scored greater than two standard deviations above published age and sex-matched norms.

RESULTS

Mean factor scores on the CBCL for children with mastocytosis did not differ significantly from published norms, but individual ratings by parents were significantly elevated in four of ten subjects. Moreover, CBCL ratings by parents were similar to those seen in other medically ill pediatric groups. None of the teacher ratings were in the pathological range.

CONCLUSIONS

The results of this study indicate that no clear excess of pathology exists in children with mastocytosis. Individual children treated with antihistamines for mastocytosis seem to have a nonspecific increase in behavioral difficulties at rates similar to other medically ill groups. No unique behavioral pattern implicating histamine overproduction was identified.
