Bulimia nervosa with history of anorexia nervosa: could the clinical subtype of anorexia have implications for clinical status and treatment response?
OBJECTIVE
To investigate whether the subtype of anorexia nervosa (AN) could influence the bulimic syndrome and treatment response in bulimia nervosa (BN) patients with a history of AN (BN/AN+).


METHODS
Seventy female BN patients were assessed for eating disorder, psychopathology and personality, and treated for 6 months.


RESULTS
BN/AN+ patients retained some traits of their past condition: lower body weight, higher perfectionism, and higher reward dependence. They also had more severe symptoms, longer evolution time, and worse response to treatment. A history of restricting AN was associated to higher age, longer evolution time, higher impulsivity, and greater tendency to use diet pills and diuretics. A history of binge-purging AN was associated to more severe vomiting, lower body dissatisfaction and less depressive symptoms, as well as better outcome.


CONCLUSIONS
The influence of the AN subtype in BN/AN+ patients is worthy of further study as it might have clinical implications.
