Analysis of 33 hospitalized COVID-19 patients with respiratory failure requiring FiO2 greater than 0.4.
Intubation hazard ratio for vitamin D sufficiency HR 0.31, p = 0.03.
This is the 5th of 184 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 712 vigintillion).
risk of mechanical ventilation, 69.0% lower, RR 0.31, p = 0.03, high D levels 4 of 21 (19.0%), low D levels 8 of 12 (66.7%), NNT 2.1, adjusted per study, >30nmol/L.

In Response to Article Entitled ‘Optimisation of Vitamin D Status for Enhanced Immuno-Protection against Covid-19’ by D.M McCartney et al - Ir Med J; Vol 113; No. 4; P58 Dear Sir, Male gender, age over 40 years, cancer, diabetes mellitus, and chronic respiratory and cardiovascular disease have each been associated with increased severity of disease, including ARDS, after SARS-CoV-2 infection.1,2 We hypothesize that nutrition might also play a role. Vitamin D (25OHD) deficiency has previously been linked to a greater susceptibility to viral infection, ARDS, and pneumonia.3,4 Since 25OHD deficiency is both highly prevalent and easily treatable and the morbidity, mortality, and costs of SARS-CoV-2 related ARDS are great, we wanted to explore whether 25OHD levels might be associated with an increased risk of the development of ARDS due to SARS-CoV-2. Following institutional review board approval and informed consent from participants, we analyzed serum 25OHD levels in 33 adult, male, Caucasian patients, over the age of 40 years, who were admitted to Connolly Hospital Blanchardstown for SARS-CoV-2 related pneumonia (four quadrant infiltrates on chest radiograph, with respiratory failure requiring FiO2 greater than 0.4, with SARS-CoV-2 detectable by RT-PCR of nasopharyngeal swab) during March 2020. None had cancer, diabetes mellitus, cardiovascular disease, or had received chronic immunosuppressive therapy. Twelve progressed to ARDS and required intubation and mechanical ventilation. There were four deaths after mechanical ventilation (at days 3, 6, 7, and 15) in the ARDS group and none in the non-ARDS group. Overall, the twelve patients who progressed to ARDS (mean age 60 years, SD 15) had a lower serum 25OHD level on presentation to hospital (mean = 27, SD = 12 nmol.l-1), compared to the twenty one patients hospitalized with less severe pneumonia who did not progress to ARDS (mean age 56 years, SD 14). Their 25OHD level was 41 nmol.l-1 (SD 19) (p = 0.03). Vitamin D (25OHD) deficiency is highly prevalent in Ireland, a country with low levels of sunlight. Using our measures of 25OHD levels from 5374 Irish males aged between 40 and 60 years, the median is 47 nmol.l-1, with 31 and 65 nmol.l-1 representing the 25th and 75th centiles, respectively. We took a cutoff of 30 nmol.l-1, or less, as being very likely to have Vitamin D deficiency. In this cohort of thirty three patients, twelve had a baseline 25OHD level less than 30 nmol.l-1. In patients with SARS-CoV-2 related pneumonia a baseline serum 25OHD level less than 30 nmol.l-1 was associated with a hazard ratio (HR) for intubation of 3.19 (95 percent confidence interval, 1.05 to 9.7), (p = 0.03). A plausible interpretation of these early..
