Treatment emergent mania responding to valproate in a Chinese female adolescent population with eating disorders: a case series.
Eating disorders are commonly associated with depressive symptoms. In an adolescent and binge eating population fluoxetine is commonly used to treat co-morbid depression associated with eating disorders. In some patients this may precipitate treatment emergent mania (TEM). Risk factors in the adolescent population include being older, female, having a longer duration of illness, more previous mood episodes, a higher prevalence of subclinical hypothyroidism, early-onset anxiety and recent exposure to a mood-elevating agent. Diagnosis and management of these co-morbid conditions is challenging due to the overlapping symptomatology and the adverse effects of both conditions complicating pharmacological management. This is illustrated with three cases in a Chinese female adolescent population that experienced TEM while on fluoxetine and responded to valproate.
