Aripiprazole as an adjunct to clozapine therapy in adolescents with early-onset schizophrenia: a retrospective chart review.
BACKGROUND
Combination of antipsychotic substances is a therapeutic option increasingly applied in patients with schizophrenia, who do not respond to antipsychotic monotherapy. Recently, various reports on combination of clozapine with aripiprazole in adults have been published. As there is not yet data on adolescent patients, we aimed to study the above-mentioned augmentation strategy in this population.


METHODS
We included 15 patients with schizophrenia from a child and adolescent psychiatric department (8 male; mean age 19.3 [SD+/-1.2, range 17.2-21.2] years). Patients had been under clozapine treatment, followed by aripiprazole augmentation. Retrospectively, patients' medical records were reviewed, using a rating scale in analogy to the Clinical Global Impressions (CGI) scale.


RESULTS
Mean observation time was 11.1 [SD+/-9.7] months. Mean CGI-Severity scores improved significantly (p=0.003, d=0.76) from 5.3 (baseline) to 4.5 (endpoint; last observation carried forward (LOCF)). CGI-Improvement scores decreased from 3.7 (after 1 month) to 3.3 (endpoint; LOCF) (p=0.212, d=0.45).


CONCLUSIONS
In adolescents with schizophrenia, aripiprazole augmentation of clozapine treatment might be an effective therapeutic strategy. Prospective studies for this age group are required to obtain more specific clinical data on clinical effectiveness.
