Deficiency symptoms: Fatigue Sufficient selenium levels prevent vitamin E deficiency and its complications. Selenium deficiency and iodine deficiency are also considered common in people affected by Keshan disease, a cardiovascular disease, and Kashin-Beck disease, a chronic bone, joint and cartilage disorder that is most prevalent in parts of Asia. Methods: We conducted an online search for articles published in the period 2010-2020 on zinc, selenium, and vitamin D, and corona and related virus infections. It is a nutritional disorder due to vitamin E and selenium deficiency. Thiamin is also important in avoiding arrhythmias. Researchers have found a close link between selenium deficiency and Peripartum Cardiomyopathy (PPCM), a heart disease that affects pregnant women and recent mothers. For example, selenium-containing antioxidant enzymes prevent the oxidation of fats in your body, which helps prevent inflammation and the build-up of plaques in your arteries. A) cardiac malfunction.

This means that, if you’re short of breath or showing signs of cardiovascular complications, it’s worth getting your serum selenium levels checked out. This is a review article telling a 50-years old story about the studies on selenium deficiency and Keshan disease in China, an endemic heart disease with high case-fatality, as an example of translational research. These damage muscle tissues of the heart and limbs (skeletal muscles). His article is to be published today in the European Journal of Heart Failure. C) Keshan disease. The study of … Introduction. Ideally, selenium should be consumed through food instead of supplements. Severe selenium deficiency plays a substantial role in Keshan disease [4], an often fatal cardiomyopathy characterized by an enlarged heart, cardiac arrhythmias, and congestive heart failure.

Selenium deficiency can be difficult to diagnose, and doctors may use a blood test that measures levels of an enzyme known as glutathione peroxidase. When there is a deficiency of selenium, harmful free radicals are generated. In contrast, a form of GSHPx associated specifically with phospholipid-rich tissue membranes is preserved against selenium deficiency and is believed to have broader metabolic roles (e.g., in prostaglandin synthesis) (6). Nutritional myodegeneration (NMD) is an acute, degenerative disease of cardiac and skeletal muscle caused by a dietary deficiency of selenium or vitamin E in young, rapidly growing calves, lambs, and kids. 1. It usually only occurs in regions with severely low selenium content in the soil, such as several regions in … But further studies need to be done to prove a definitive link between selenium supplementation and improvement in these health conditions. 2.

The aim of the present article was to explore the usefulness of early micronutrient intervention, with focus on zinc, selenium, and vitamin D, to relieve escalation of COVID-19. An impairment of selenoprotein biosynthesis may be a factor in congestive heart failure, reminiscent of the dilated cardiomyopathies seen with selenium deficiency. Selenium Deficiency in Calves. Selenium deficiency is linked to heart damage as in. The role of selenium in cancer treatment is currently being studied. 2 This is the case with Keshan disease, a potentially fatal cardiomyopathy (disease of the heart muscle). The GSHPx enzymes of liver and blood plasma fall in activity rapidly at early stages of selenium deficiency. In the 200 years since its discovery in 1817, the role of selenium … Muscle weakness. Improving selenium nutrition status in children has been linked to the reduction of Kashin-Beck disease, a disease that is characterized by the degeneration of cartilage between joints 3 . Due to its overall effects in the body, research is being conducted on whether or not selenium supplementation may affect glucose metabolism, as well as help prevent cancer, thyroid disease, heart disease, and the cognitive decline that occurs as we age. Selenium helps in the prevention of premature aging, cancer, arteriosclerosis, cirrhosis, arthritis, and stroke. Selenium deficiency in patients with heart failure consequently causes reduced exercise tolerance, poorer quality of life and a 50% higher mortality rate, as research by postdoc researcher Nils Bömer of the UMCG has found. Deficiency, although relatively rare in healthy well-nourished individuals, can have significant negative results, affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation. Selenium is a mineral found in soil, water, and some foods. Selenium deficiency is very rare in the United States and Canada. WMD results in the destruction of normal skeletal and cardiac muscle.
