Course and Survival of COVID-19 Patients with Comorbidities in Relation to the Trace Element Status at Hospital Admission.

Selenium (Se) and zinc (Zn) are essential trace elements needed for appropriate immune system responses, cell signalling and anti-viral defence. A cross-sectional observational study was conducted at two hospitals in Ghent, Belgium, to investigate whether Se and/or Zn deficiency upon hospital admission correlates to disease severity and mortality risk in COVID-19 patients with or without co-morbidities. Trace element concentrations along with additional biomarkers were determined in serum or plasma and associated to disease severity and outcome. An insufficient Se and/or Zn status upon hospital admission was associated with a higher mortality rate and a more severe disease course in the entire study group, especially in the senior population. In comparison to healthy European adults, the patients displayed strongly depressed total Se (mean ± SD: 59.2 ± 20.6 vs. 84.4 ± 23.4 µg L-1) and SELENOP (mean ± SD: 2.2 ± 1.9 vs. 4.3 ± 1.0 mg L-1) concentrations at hospital admission. Particularly strong associations were observed for death risk of cancer, diabetes and chronic cardiac disease patients with low Se status, and of diabetes and obese patients with Zn deficiency. A composite biomarker based on serum or plasma Se, SELENOP and Zn at hospital admission proved to be a reliable tool to predict severe COVID-19 course and death, or mild disease course. We conclude that trace element assessment at hospital admission may contribute to a better stratification of patients with COVID-19 and other similar infectious diseases, support clinical care, therapeutic interventions and adjuvant supplementation needs, and may prove of particular relevance for patients with relevant comorbidities.

Vitamin D supplementation prior to or during COVID-19 associated with better 3-month survival in geriatric patients: Extension phase of the GERIA-COVID study.

BACKGROUND: The objective of this extension phase of the quasi-experimental GERIA-COVID study was to determine whether vitamin D3 supplementation taken prior to or during COVID-19 was associated with better 3-month survival in geriatric patients hospitalized for COVID-19. METHODS: Intervention group was defined as all participants supplemented with vitamin D3 prior to or during COVID-19 (n = 67). Supplements were either bolus vitamin D3 (ie, 50,000 IU per month, or 80,000 IU or 100,000 IU or 200,000 IU every 2-3 months), or daily supplementation with 800 IU. Comparator group involved those without vitamin D supplements (n = 28). Outcome was 3-month mortality. Covariables were age, sex, functional abilities, history of malignancies, cardiomyopathy, undernutrition, number of acute health issues, antibiotics use, systemic corticosteroids use, and 25(OH)D concentration. RESULTS: 76.1 % (n = 51) of participants survived at 3 months in Intervention group, compared to only 53.6 % (n = 15) in Comparator group (P = 0.03). The fully-adjusted hazard ratio for 3-month mortality was HR = 0.23 [95 %CI: 0.09;0.58](P = 0.002) in Intervention group compared to Comparator group. Intervention group had also longer survival time (log-rank P = 0.008). CONCLUSIONS: Vitamin D3 supplementation was associated with better 3-month survival in older COVID-19 patients.

Evaluation of nutritional status in pediatric patients diagnosed with Covid-19 infection.

AIM: The aim of this study was to evaluate the nutritional status, the nutritional effect on the risk of infection and the severity of the disease, and the contribution of nutrition to the course of the infection in pediatric patients diagnosed with coronavirus disease who required additional nutritional support after hospitalization. METHODS: The body weight, height, body mass index, upper arm circumference, and triceps skinfold thickness of 49 patients aged 1 month to 18 years and diagnosed with Covid-19 and then hospitalized at the Ankara City Hospital, Pediatric Health and Diseases Hospital, Pediatric Infection ward between 15 May and 15 June 2020 were measured. Total protein, albumin, prealbumin, selenium, zinc, ferritin, folate, and selenium, C, D, E, and B12 levels were studied from blood drawn simultaneously from the patients. RESULTS: A total of 49 patients aged 8-18 years were evaluated. The median age was 13 years (age range 8-18). The females made up 53% and the males 47% of the group. No patient needed intensive care admission. Only 3 patients received antibiotic treatment and the others were followed up without treatment. The weight was normal in 75% and the height was normal in 90%. Mid-arm circumference and triceps thickness were normal in 72% of the patients. Vitamin D deficiency was present in 82%, vitamin B12 deficiency in 18%, vitamin C deficiency in 17%, ferritin deficiency in 16%, folate deficiency in 15%, vitamin A deficiency in 13%, and vitamin E deficiency in 7%. CONCLUSION: No patient required intensive care admission. Only 3 patients received antibiotic treatment and the others were followed up without treatment. Malnourishment was present in 3% of the patients while 9% were obese. Vitamin D deficiency was the most common vitamin deficiency while vitamin B12, vitamin C, Ferritin, vitamin A, vitamin E, and Folate deficiency were less common. Selenium and zinc levels were normal in all patients. There was no correlation between anthropometric values and susceptibility to childhood COVID-19 infection or the clinical course. It is possible that vitamin D deficiency increases susceptibility to the infection.

Malnutrition: Percentage and Association with Prognosis in Patients Hospitalized for Coronavirus Disease 2019.

Previous studies have found a correlation between malnutrition and prognosis in respiratory infections. Our objectives were to determine (i) the percentage of malnutrition, and (ii) its prognosis in patients admitted for coronavirus disease 2019 (COVID-19). In this monocentric retrospective study, we consecutively included all adult patients presenting with acute COVID-19 between 9 April and 29 May 2020. Malnutrition was diagnosed on low body mass index (BMI) and weight loss ≥ 5% in the previous month and/or ≥10% in the previous six months. The Nutritional Risk Index (NRI) defined nutritional risk. Severe COVID-19 was defined as a need for nasal oxygen ≥ 6 L/min. We enrolled 108 patients (64 men, 62 ± 16 years, BMI 28.8 ± 6.2 kg/m2), including 34 (31.5%) with severe COVID-19. Malnutrition was found in 42 (38.9%) patients, and moderate or severe nutritional risk in 83 (84.7%) patients. Malnutrition was not associated with COVID-19 severity. Nutritional risk was associated with severe COVID-19 (p < 0.01; p < 0.01 after adjustment for C reactive protein), as were lower plasma proteins, albumin, prealbumin, and zinc levels (p < 0.01). The main cause of malnutrition was inflammation. The high percentage of malnutrition and the association between nutritional risk and COVID-19 prognosis supports international guidelines advising regular screening and nutritional support when necessary.
