Praziquantel can be useful for treating infections caused by all Schistosoma species. Hydroxychloroquine and chloroquine can use in the therapy of sarcoidosis involving the skin, lungs, and the nervous system. The use of anti-TNF monoclonal antibodies such as adalimumab and certolizumab have been approved for Crohn disease. [20]
The manifestations of histamine intolerance are usually systemic, affecting the entire body; still, these symptoms are often sporadic and non-specific. [5] [6] [7] The onset of symptoms is usually shortly (within a few hours) after specific food or drink consumption, and subsequent remission usually happens in 4-8 weeks of dieting, [8] that is excluding food that causes the onset of symptoms.
The role of histamine in health and disease is an area of ongoing research. For example, histamine is researched in its potential link with migraine episodes, when there is a noted elevation in the plasma concentrations of both histamine and calcitonin gene-related peptide (CGRP).
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or ...
Histamine receptors expressed in smooth muscles, vascular endothelial cells, the heart, and the central nervous system. [7] This prevents a range of cellular signaling cascades that lead to vasodilation and increased membrane permeability from happening, thus preventing allergic symptoms.
Another gap in the research is in information reporting the health effects for individuals with long-term allergies who take antihistamines for a long period of time. [1] Newer antihistamines have been demonstrated to be effective in treating hives. [1] However, there is no research comparing the relative efficacy of these drugs. [1]
Mast cells serve the same general functions in the body and central nervous system, such as effecting or regulating allergic responses, innate and adaptive immunity, autoimmunity, and inflammation. [4] [18] Across systems, mast cells serve as the main effector cell through which pathogens can affect the gut–brain axis. [19] [20]
The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. [13] Diagnosis is typically based on a person's medical history. [3]
