The Active Metabolite of Vitamin D3 as a Potential Immunomodulator. In the past, vitamin D was known for its classical, skeletal action as a regulator of calcium and bone homoeostasis. Currently, vitamin D was found to have a role in numerous physiological processes in the human body; thus, vitamin D has pleiotropic activity. The studies carried out in the past two decades showed the role of vitamin D in the regulation of immune system functions. Basically, these effects may be mediated not only via endocrine mechanism of circulating calcitriol but also via paracrine one (based on ...

Prevalence of IgG-mediated food intolerance among patients with allergic symptoms BACKGROUND: Food intolerance mediated by food specific IgG antibodies has been implicated in a variety of disorders. OBJECTIVES: To assess the prevalence of food specific IgG antibodies among patients clinically presenting with allergic symptoms lacking laboratory evidence of allergy. DESIGN: Descriptive retrospective cross-sectional study. SETTING: King Khalid University Hospital, Riyadh between 2010-2015. PATIENTS AND METHODS: Patients were screened for food specific IgG antibodies. All symptomatic ...

Presumed Allergic Proctocolitis Resolves with Probiotic Monotherapy: A Report of 4 Cases. The prevalence of allergic diseases has been dramatically rising in the United States and other developed nations over recent decades. Growing evidence suggests a partial role for the microbiome in the development of these allergic diseases. Food protein-induced allergic proctocolitis (AP) (also referred to as cow’s milk protein intolerance or allergy) is among the earliest and most common food allergic diseases of infancy, yet its pathophysiology is not well understood. The currently accepted ...

Natural Phyto-Bioactive Compounds for the Treatment of Type 2 Diabetes: Inflammation as a Target Diabetes is a metabolic, endocrine disorder which is characterized by hyperglycemia and glucose intolerance due to insulin resistance. Extensive research has confirmed that inflammation is closely involved in the pathogenesis of diabetes and its complications. Patients with diabetes display typical features of an inflammatory process characterized by the presence of cytokines, immune cell infiltration, impaired function and tissue destruction. Numerous anti-diabetic drugs are often ...

Immunology of breast milk In the critical phase of immunological immaturity of the newborn, particularly for the immune system of mucous membranes, infants receive large amounts of bioactive components through colostrum and breast milk. Colostrum is the most potent natural immune booster known to science. Breastfeeding protects infants against infections mainly via secretory IgA (SIgA) antibodies, but also via other various bioactive factors. It is striking that the defense factors of human milk function without causing inflammation; some components are even anti-inflammatory. ...

Immune Modulation by Vitamin D and Its Relevance to Food Allergy. Apart from its classical function in bone and calcium metabolism, vitamin D is also involved in immune regulation and has been linked to various cancers, immune disorders and allergic diseases. Within the innate and adaptive immune systems, the vitamin D receptor and enzymes in monocytes, dendritic cells, epithelial cells, T lymphocytes and B lymphocytes mediate the immune modulatory actions of vitamin D. Vitamin D insufficiency/deficiency early in life has been identified as one of the risk factors for food allergy. ...
