Abstract
Objectives
The aim of this study was to determine an association between ionized calcium (CaI) levels and mortality 3 months after Covid-19 infection in geriatric population.
Design
Observational retrospective cohort study.
Setting and participants
One hundred and seventy-nine patients hospitalized in the geriatric acute care unit of Angers University Hospital were included. This specific unit specifically dedicated to COVID-19 patients was opened for 2 periods : from March 1, 2020 to June 30, 2020 and from October 1, 2020 to March 29, 2021. Covariates considered were: age, sex, Iso-Resources Groups (GIR) score ≤ 3, Parathyroid hormone (PTH), C-Reactive Protein (CRP), severe undernutrition defined as albumin < 30 g/L, history of cancer, history of cardiomyopathy, severe chronic renal failure (defined as clearance < 30 ml/min), Ordinal Scale for Clinical Improvement (OSCI) score, use of systemic corticosteroids and usual vitamin D supplementation. Direct potentiometry was also used as a covariate.
Measurements
The time elapsed between the diagnosis of COVID-19 and death was studied by survival curves calculated using Cox model in each group defined by serum CaI concentration (>1.22 and ≤1.22 mmol/L).
Results
In the Cox model, a significant association was found between CaI over 1.22 mmol/l and 3-months mortality, analyzed in an adjusted model (HR 2.40 [1.34–4.31], p = 0.003).
Conclusion
There is an association between CaI and 3 months mortality in geriatric patients hospitalized for COVID-19.
期刊介绍:
There is increasing scientific and clinical interest in the interactions of nutrition and health as part of the aging process. This interest is due to the important role that nutrition plays throughout the life span. This role affects the growth and development of the body during childhood, affects the risk of acute and chronic diseases, the maintenance of physiological processes and the biological process of aging. A major aim of "The Journal of Nutrition, Health & Aging" is to contribute to the improvement of knowledge regarding the relationships between nutrition and the aging process from birth to old age.
