COVID-19 symptoms vary from asymptomatic cases to moderate and severe illness with patients needing hospitalization and intensive care treatment. Vitamin D is associated with severity of viral infections and has an immune-modulatory effect in immune response. Observational studies showed a negative association of low vitamin D levels and COVID-19 severity and mortality outcomes. In this study, we aimed to determine whether daily supplementation of vitamin D during intensive care unit (ICU) stay in COVID-19 patients with severe illness affects clinically relevant outcomes. Patients with COVID-19 disease in need of respiratory support admitted to the ICU were eligible for inclusion. Patients with low vitamin D levels were randomized into one of two groups: the intervention group received daily supplementation of vitamin D and the control group did not receive vitamin D supplementation. In total, 155 patients were randomized: 78 into the intervention group and 77 into the control group. There was no statistically significant difference in number of days spent on respiratory support, although the trial was underpowered for the main outcome. There was no difference in any of the secondary outcomes analyzed between two groups. Our study suggests no benefit in vitamin D supplementation to patients with severe COVID-19 disease admitted to the ICU and in need of respiratory support in any of the analyzed outcomes

Purpose: To investigate the quality of life (QoL) of survivors from severe forms of COVID-19 treated in the ICU. Methods: In this study, we investigated the QoL of patients with severe COVID-19 treated in the ICU from November 2021 to February 2022. In the study period, 288 patients were treated in ICU and 162 were alive at the time of analysis. Of those, 113 patients were included in this study. QoL was analyzed 4 months after ICU admission using the EQ-5D-5L questionnaire administered by telephone. Results: Of the 162 surviving patients, 46% reported moderate to severe problems in the anxiety/depression domain, 37% had moderate to severe problems in usual activities, and 29% in the mobility domain. Older patients had lower QoL in mobility, self-care and usual activities domains. Female patients had lower QoL in usual activities, while male patients had lower QoL in the self-care domain. Patients who spent longer time on invasive respiratory support and those with longer hospital lengths of stay had lower QoL in all domains. Conclusion: Severe COVID-19 reduces HRQoL in a significant number of survivors 4 months after ICU admission. Early recognition of patients at increased risk for reduced QoL could lead to early focused rehabilitation and improved QoL of these patients.
