Résumé :

The nyctohemeral patterns of serum thyrotropin (TSH) levels were studied in thirteen female patients suffering from primary affective illness (5 bipolars and 8 unipolars); they were compared to the nyctohemeral profiles obtained in six normal female subjects. The periodogram analysis showed striking differences in TSH circadian rhythms between unipolar and bipolar patients. The nyctohemeral TSH patterns in bipolar patients were similar to those obtained in controls. Unipolar patients, compared to controls, had a significantly lower 24-hour TSH mean, a lower sleep-wake ratio of TSH and an absence of nocturnal rise of TSH. The alterations of the circadian rhythm of TSH secretion observed in the depressive phase of unipolar illness may be a relevant neuroendocrine indicator of hypothalamic-pituitary dysfunction in primary depressive illness. © 1980, All rights reserved.
