Vitamin D Perspective in Front Line Healthcare Workers Amid COVID-19
##plugins.themes.bootstrap3.article.main##
Deficiency of Vitamin D is very common in Pakistan, even among healthy asymptomatic individuals [1], [2]. Recent studies have shown that the risk of contracting COVID-19 was increased to two-fold, and consequent mortality to 4-fold if the person is Vitamin D deficient [3]. Health care workers including the nursing and administration staff are at a high risk of contracting SARS-CoV2 due to increased regular exposure in a health care setting [4]. Consequently, a convergence of the COVID-19 pandemic, the deficiency of Vitamin D, and the increased exposure can render the health care workers at an additional risk to COVID-19 infection. Our objective was to determine the prevalence of vitamin D deficiency in healthy asymptomatic front-line health care workers and to analyze the change in serum level by loading oral dose of SunnyD STAT softgel capsules (200000 IU Vitamin D3). We followed single centered, cross-sectional, cohort study with subsequent randomized placebo-controlled design for supplementation and follow up. Serum level of 25-hydroxyvitamin D (25OHD) was the main outcome variable, with anthropometric data, nutritional intake, and lifestyle variables analyzed for potential association as risk factors for the outcome. Severe Vitamin D deficiency was found to be prevalent among front line health care workers in this urban hospital-based sample. Serum level of Vitamin D was found to be significantly associated with designation and presence of high blood pressure. The likelihood of increased serum Vitamin D levels was observed with increasing monthly income, higher designation, increasing age and supplementation intake. Mean increase in the serum 25(OH)D3 level after 2 doses of SunnyD STAT softgel capsule (200000 IU Vitamin D3) was 34.22 ng/ml. Public health interventions regarding Vitamin D supplementation and awareness are needed, especially amid COVID-19 pandemicDeficiency of Vitamin D is very common in Pakistan, even among healthy asymptomatic individuals [1], [2].
