Background: The use of valproate in the treatment of Anorexia Nervosa (AN) in children and adolescents is currently not recommended by clinical guidelines, due to lack of evidence. Nonetheless, valproate is used to treat a series of psychiatric and neurologic conditions. To date, only six cases of patients with Feeding and Eating Disorders (three with AN) have been described. Methods: Case series of 14 children and adolescent patients hospitalized for AN and treated with valproate as an adjunctive treatment. Reasons for introduction, dosages, plasma levels, adverse drug reactions (ADR) and modifications of liver enzymes, platelets levels, abdominal and pelvic ultrasounds, and concurrent drugs plasma levels were assessed. Results: Reasons for the introduction of valproate included unstable mood (57.1%), lack of compliance (50%) and aggressive behaviour (21.4%). In 71.4% of patients an improvement on target symptoms was observed. Valproate was started at 241.7 (± 73.3) mg, up to 521.4 (± 204.5) mg; the most frequent scheme was twice-daily. The mean plasmatic concentration was 66.3 (± 25.0) mg/L. One patient (7.1%) experienced side effects (somnolence). No major modifications of liver enzymes, platelet levels, abdominal and pelvic ultrasounds emerged after the introduction of valproate. Low concurrent olanzapine and quetiapine levels were documented. Conclusions: This is the largest sample of patients with AN treated with valproate. Valproate was administered to improve psychiatric symptoms impairing compliance with inpatient treatment programs. The majority of patients experienced an improvement on target symptoms after being administered valproate, with minor ADR. These data should be investigated in wider populations and controlled studies.

Abstract

Background: The use of valproate in the treatment of Anorexia Nervosa (AN) in children and adolescents is currently not recommended by clinical guidelines, due to lack of evidence. Nonetheless, valproate is used to treat a series of psychiatric and neurologic conditions. To date, only six cases of patients with Feeding and Eating Disorders (three with AN) have been described. Methods: Case series of 14 children and adolescent patients hospitalized for AN and treated with valproate as an adjunctive treatment. Reasons for introduction, dosages, plasma levels, adverse drug reactions (ADR) and modifications of liver enzymes, platelets levels, abdominal and pelvic ultrasounds, and concurrent drugs plasma levels were assessed. Results: Reasons for the introduction of valproate included unstable mood (57.1%), lack of compliance (50%) and aggressive behaviour (21.4%). In 71.4% of patients an improvement on target symptoms was observed. Valproate was started at 241.7 (± 73.3) mg, up to 521.4 (± 204.5) mg; the most frequent scheme was twice-daily. The mean plasmatic concentration was 66.3 (± 25.0) mg/L. One patient (7.1%) experienced side effects (somnolence). No major modifications of liver enzymes, platelet levels, abdominal and pelvic ultrasounds emerged after the introduction of valproate. Low concurrent olanzapine and quetiapine levels were documented. Conclusions: This is the largest sample of patients with AN treated with valproate. Valproate was administered to improve psychiatric symptoms impairing compliance with inpatient treatment programs. The majority of patients experienced an improvement on target symptoms after being administered valproate, with minor ADR. These data should be investigated in wider populations and controlled studies.
