Treatment adherence and tolerability of immediate- and prolonged-release lithium formulations in a sample of bipolar patients: a prospective naturalistic study.

Int Clin Psychopharmacol 2021 Sep;36(5):230-237

Psychiatry 2 Unit, Department of Clinical and Experimental Medicine, University of Pisa.

The aim of this study was to compare treatment adherence and tolerability of different lithium formulations in 70 bipolar patients receiving lithium therapy for the first time. During the 1-year follow-up, information was collected regarding patient's clinical course, therapeutic adherence, side effects of the treatment and serum levels of lithium, creatinine and thyroid-stimulating hormone. At baseline, 30 patients (43%) were on prolonged-release lithium formulations and 40 (57%) on immediate-release formulations. At the final evaluation, 37 patients (53%) were considered lost to follow-up. Both prolonged- and immediate-release patients showed significant improvement in the Functioning Assessment Short Test and in the Clinical Global Impressions for Bipolar Disorder scores during the follow-up. At the first follow-up visit, the mean plasma lithium level of prolonged-release patients was higher than immediate-release patients (0.61 vs. 0.47, respectively; P = 0.063), as well as the therapeutic adherence (85 vs. 64%, respectively; P = 0.089). Fine tremor and gastrointestinal symptoms were more frequent in immediate-release patients than in prolonged-release patients at each follow-up visit, with the sole exception of gastrointestinal symptoms at the last evaluation. Prolonged-release lithium therapy could provide potential advantages over immediate-release formulations. Future naturalistic studies and clinical trials with a longer follow-up duration are needed.

Vitamin D: A Pleiotropic Hormone with Possible Psychotropic Activities.

Curr Med Chem 2021 ;28(19):3843-3864

Department of Clinical and Experimental Medicine, Section of Psychiatry, University of Pisa, Italy.

Background: After the recognition of the efficacy of cod-liver oil in rickets at the end of the eighteenth century, and the isolation and synthesis of the liposoluble vitamin D in 1931, its mode of actions and functions were deeply explored. Biochemical studies permitted to identify five forms of vitamin D, called D1, D2, D3, D4 and D5, differing in ultrastructural conformation and origin, with vitamin D2 (ergocalciferol) and D3 (cholecalciferol) representing the active forms. In the last decades especially, a constantly increasing bulk of data highlighted how vitamin D could regulate several activities and processes.

Aims: The aim of the present paper was to review and comment on the literature on vitamin D, with a focus on its possible role in the pathophysiology of neuropsychiatric disorders.

Discussion: Available literature indicates that vitamin D regulates a variety of processes in humans and in the central nervous system. Vitamin D deficiency is associated with an enhanced pro-inflammatory state, and formation of Aβ oligomers that might contribute to the cognitive decline typical of the elderly age and, perhaps, dementia. More in general, vitamin D is supposed to play a crucial role in neuroinflammation processes that are currently hypothesized to be involved in the pathophysiology of different psychiatric disorders, such as major depression, bipolar disorders, obsessive-compulsive disorders and psychosis.

Conclusion: It is conceivable that vitamin D supplementation might pave the way towards "natural" treatments of a broad range of neuropsychiatric disorders, or at least be useful to boost response to psychotropic drugs in resistant cases.
