Estrogen in Severe Mental Illness: A Potential New Treatment Approach

Kulkarni, Jayashri, de Castella, Anthony, Fitzgerald, Paul B., Gurvich, Caroline T., Bailey, Michael, Bartholomeusz, Cali, Burger, Henry·2008·Archives of General Psychiatry

Abstract

CONTEXT: Accumulating evidence suggests that estrogens may have therapeutic effects in severe mental illnesses, including schizophrenia, via neuromodulatory and neuroprotective activity. OBJECTIVE: To compare the efficacy of adjunctive transdermal estradiol with that of adjunctive placebo in the treatment of acute psychotic symptoms. DESIGN: Randomized, double-blind study. SETTING: Patients were recruited from inpatient acute hospital wards and outpatient clinics of 2 metropolitan Melbourne general hospitals. PARTICIPANTS: One hundred two women of childbearing age with schizophrenia. All participants were in an acute or chronic phase of their illness; 73 participants were outpatients and the rest were inpatients. Intervention Patients were randomized to receive 100 microg of transdermal estradiol (n = 56) or transdermal placebo (n = 46) for 28 days. MAIN OUTCOME MEASURES: Psychopathological symptoms were assessed weekly with the Positive and Negative Syndrome Scale. RESULTS: The addition of 100 microg of transdermal estradiol significantly reduced positive (P < .05) and general psychopathological (P < .05) symptoms during the 28-day trial period compared with women receiving antipsychotic medication alone. CONCLUSION: Estradiol appears to be a useful treatment for women with schizophrenia and may provide a new adjunctive therapeutic option for severe mental illness. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00206570.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
