A case of systemic lupus erythematodes (SLE) with development of a del
usional depression is presented. Psychiatric symptoms in patients with
SLE and in patients treated with glucocorticoids are discussed. The m
ain psychiatric side effects of a therapy with steroids are a dose-dep
endent, reversible dementia like syndrome and a probably not dose-depe
ndent provocation of psychosis. Furthermore the role of the dysregulat
ion of the limbic-hypothalamic-pituitary-adrenocortical axis in major
depression is stressed and consequences for psychopharmacological trea
tment are emphasized.
