Clinical and laboratory effects of discontinuation of lithium prophylaxis.
Twelve patients who met Research Diagnostic Criteria for a history of bipolar affective disorder gave informed consent for open discontinuation of lithium therapy for 3 weeks. There was no significant change after lithium discontinuation in the number of depressive or manic symptoms, in mood score, in total Zung Depression score, or in any of the 20 items found in the Zung Depression scale. There were significant reductions in total severity of side effects, and improvement in the three side effects reflecting renal function: polydipsia, polyuria, and nocturia. These changes were reflected in the significant increase in urine specific gravity. Significant changes in side effects did not take place until at least 2 weeks after lithium was discontinued. Other significant relationships were found between increases in serum thyroid hormone levels and in urine specific gravity, and decreases in Vmax of platelet serotonin uptake and increases in degree of clonidine-induced hypotension.
