The Covid-19 infection: An opportunity to develop systematic vitamin D supplementation in psychiatry

G Fond et al. Encephale. 2022 Feb.

Abstract
in English, French

Psychiatric patients are at risk of hypovitaminosis D and Covid-19-related mortality. In addition to the mental health benefits, vitamin D supplementation may be potentially effective in preventing severe forms of Covid-19 infections. Vitamin D supplementation is not necessary and is not reimbursed in France for this indication. A monthly supplementation of 50,000 IU may be sufficient in most cases. Double the dose is recommended for obese patients. The risk of renal lithiasis is not increased at these doses, even when supplemented in a patient without vitamin D deficiency. The Covid-19 crisis is an opportunity to disseminate vitamin D supplementation in psychiatric patients, as it has been shown to be effective in other respiratory diseases such as mild upper respiratory tract infections and influenza.

Les patients psychiatriques sont à risque d’hypovitaminose D et de mortalité liée au Covid-19. En plus des bénéfices sur la santé mentale, la supplémentation en vitamine D peut être potentiellement efficace pour prévenir les formes graves d’infections au Covid-19. Un dosage de vitamine D n’est pas nécessaire et n’est pas remboursé en France dans cette indication. Une supplémentation mensuelle de 50 000 UI pourrait être suffisante dans la plupart des cas. Le double de la dose est recommandé pour les patients obèses. Le risque de lithiase rénale n’est pas augmenté à ces doses, même en cas de supplémentation chez un patient sans carence en vitamine D. La crise du Covid-19 est une opportunité pour diffuser la supplémentation en vitamine D chez les patients psychiatriques, elle a en effet fait ses preuves sur d’autres pathologies respiratoires comme les infections bénignes de voies aériennes supérieures et la grippe.
