Poor vitamin D status is associated with greater susceptibility to viral infections, including those of the respiratory tract. Although the severity of the COVID-19 pandemic has been alleviated in some areas by the arrival of vaccines, it remains important to identify therapeutic interventions that ...
Vitamin E-induced enhancement of immune functions has significant clinical implications as evidenced by the findings that vitamin E supplementation is associated with increased resistance to respiratory infections in both aged mice and older adults. In this chapter, we review age-related changes in the...
associated with significant morbidity and mortality. Vitamin D (1,25(OH)2D3) deficiency has been shown to be highly prevalent in patients with chronic airway inflammatory and infectious diseases, correlated with increased disease severity. It has been established that vitamin D...
Control of human immunodeficiency virus (HIV) and Mycobacterium tuberculosis infections requires type 1 cytokine (cellular) immunity. These infections and vitamin A deficiency are highly prevalent in Africa. We therefore examined the interactions among serum vitamin A levels, immune parameters, HIV ...
Upper respiratory tract infections had been inversely associated with sun exposure. During the last decade, basic scientific research demonstrated that vitamin D has an important anti-infective role. Method: Review of the relevant literature on the influence of vitamin D on innate immunity and ...
Vitamin D deficiency in mothers and infants is a global health disorder despite recognition that it is preventable. Recent data support the theory that vitamin D deficiency in adults and children may increase the risk of infections and auto-immune diseases. In most cases, vitamin D deficiency is...
Vitamin D levels are alarmingly low (<75 nmol/L) in 65-70% of North American children older than 1 year. An increased risk of viral upper respiratory tract infections (URTI), asthma-related hospitalizations and use of anti-inflammatory medication have
Research shows that vitamin D plays an important role in immune function, and a deficiency in it is shown toincrease your susceptibility to infection. "Somestudies have shownthat vitamin D deficiency is even associated with greater risk of self-reported upper respiratory tract infections," Tolentino...
Data on non-mycobacterial infections in humans are also correlated with urinary and respiratory infections and sepsis. It suggests susceptibility to urinary tract infection in children who have low vitamin D levels owing to decreased cAMP production and defense of β2 [100]. In addition to that, ...
Abstract This chapter will examine the role of vitamin D in the innate immune system as a mediator of human host defense mechanisms microbial disease, focusing on tuberculosis. The first section will examine tuberculosis and the innate immune response to the intracellular pathogen,Mycobacterium tuberculo...
