When interpreting the study findings, however, it is important to bear in mind that these are associations and no causal relationship can be derived from them. The benefit of vitamin D supplementation in certain risk groups with osteological or musculoskeletal complaints is undisputed. Benefit is also expected in certain other indications.<\/strong><\/p>\n<p> <!--more--> <\/p>\n<p>A recent meta-analysis concluded that severe COVID-19 courses are 64% more likely to be vitamin D deficient than mild courses [1,2]. Inadequate vitamin D levels were inversely associated with an increased risk of hospitalizations (OR 1.81, CI 1.41-2.21) and excess mortality (OR 1.82, CI 1.06-2.58) [2]. In this context, the question arises whether vitamin D administration might be useful for COVID-19 infection prophylaxis or therapy. International professional societies have issued current statements on this subject.<\/p>\n<p>In a recently published expert statement, the German Society of Endocrinology assessed the current evidence as insufficient for a preventive effect of vitamin D in the context of COVID-19 [3]. The National Institute for Health (NICE) of the United Kingdom also came to this conclusion based on a comprehensive secondary analysis of study findings [4]. That an association exists between vitamin D status and a worse clinical COVID-19 course was confirmed, but no causal relationship could be inferred from this. According to the German Society of Endocrinology [3], it remains an individual decision of the physician and patient whether the measurement of vitamin D levels and any vitamin supplementation is useful or not. There are also recent publications on the fact that an overdose of vitamin D can have harmful effects [6,7]. As a pragmatic solution, the professional society therefore suggests 400-1000&nbsp;IU vitamin supplementation per day&nbsp; to ensure adequate vitamin D supply in risk groups [1].<\/p>\n<p>The patients considered at risk according to the Swiss guidelines are shown in <span style=\"font-family:franklin gothic demi\">overview&nbsp;1<\/span>.<\/p>\n<p>&nbsp;<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\" size-full wp-image-16093\" alt=\"\" src=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20.png\" style=\"height:321px; width:600px\" width=\"1100\" height=\"589\" srcset=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20.png 1100w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20-800x428.png 800w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20-120x64.png 120w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20-90x48.png 90w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20-320x171.png 320w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht1_hp4_s20-560x300.png 560w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"size-full wp-image-16094 lazyload\" alt=\"\" data-src=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20.png\" style=\"--smush-placeholder-width: 1100px; --smush-placeholder-aspect-ratio: 1100\/484;height:264px; width:600px\" width=\"1100\" height=\"484\" data-srcset=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20.png 1100w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20-800x352.png 800w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20-120x53.png 120w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20-90x40.png 90w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20-320x141.png 320w, https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/04\/ubersicht2_hp4_s20-560x246.png 560w\" data-sizes=\"(max-width: 1100px) 100vw, 1100px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"assess-the-question-of-supplementation-individually\">Assess the question of supplementation individually<\/h2>\n<p>The effects of vitamin D on bone health are well established empirically [1] and in all the discussions on possible effects on COVID-19 infection, it should not be forgotten that for certain osteological or musculoskeletal risk groups there is an established need for vitamin D supplementation, which also applies in the context of COVID-19 [1,3]. Outside the indication of bone health, however, the data situation so far remains &#8220;without clear evidence of a benefit of vitamin D,&#8221; concluded the German Society for Endocrinology in a statement published in February of this year [3]. On the one hand, there are numerous empirical findings on associations of the vitamin D signaling pathway with immune system function and tumorigenesis [3]. On the other hand, vitamin D is downregulated in the context of inflammatory processes, and there are numerous pathophysiological explanations for reverse causality pointing to low vitamin D levels as a consequence rather than a cause of adverse health events.
