Background: The coronavirus disease 2019 (COVID-19) pandemic led to changes in lifestyle, which could influence vitamin D status on a population level. The purpose of our study was to compare 25-hydroxyvitamin D (25[OH]D) levels in patients hospitalized because of severe COVID-19 during two waves of the pandemic (2020/21 vs. 2021/22).Materials and methods: We analyzed 101 patients (61 males/ 40 females) hospitalized in the internal medicine department of...

Introduction: Adult growth hormone deficiency (AGHD) is associated with lower bone mass and likely with increased risk of fragility fractures. GH replacement leads to increase in bone mineral density (BMD) and trabecular bone score (TBS). The effect of adequate levels of vitamin D during GH replacement is important to provide effect on TBS.Aim: To assess long–term effectof recombinant GH replacement on BMD and TBS with regards to vitamin D levels d...

Objectives: There is no consensus about specific serum 25(OH)D levels associated with higher risk of severe outcome in COVID-19 patients. According to the literature patients with serum 25(OH)D levels < 12 ng/ml are clearly deficient at all ages. Our aim was to assess COVID-19 mortality in the settings of severe 25(OH)D deficiency.Methods: A cohort study of 357 COVID-19 patients was conducted. Subjects were monitored until discharge or in-hospital de...
