Nasal Airway Inflammation In Allergic Rhinitis

Nasal Airway Inflammation
Allergic rhinitis is an inflammatory nasal disorder in which a range of different cells participate. A variety of approaches has been used to monitor nasal inflammation objectively to investigate disease processes and to evaluate the effect of therapeutic intervention. These approaches include nasal lavage, nasal cytology and nasal biopsy, together with the more recently established measurement of nasal nitric oxide (NO) concentration. Although all provide information about nasal mucosal inflammation, the extent of information that can be obtained by each approach, the ease of sampling, and the complexity of sample handling differ.

Drug Allergy Reaction Classification – Immune Reactions

drug allergy reaction
Drug allergy reactions may be classified, at least theoretically, according to one of four implicated immunologic mechanisms, according to the scheme of Gell and Coombs:

Type I Drug Allergy Reactions

Type I reactions are the result of an IgE antibody reaction, which induces immediate-type hypersensitivity reactions. (more…)

Antibodies and the Immune Response - Human Immune System

B cells

The main function of B cells is to produce antibodies. Antibodies are complex molecules produced by the immune system in response to antigens. As mentioned previously, antigens are foreign proteins or glycoproteins (a sugar linked to a protein) that trigger the immune response. Every living cell produces several different proteins, each unique to its own cell type and species. The antibody produced against the antigen is entirely specific to that antigen. (more…)

Airway Vascularity in Asthma

The airway circulation has many potential roles in asthma. The vasculature has a major influence on upper airway patency in nasal infection and atopic responses. Given its responsiveness to provocative stimuli in asthma and vasoconstrictive and antiproliferative response to corticosteroids, the bronchial circulation is likely to be a future target for novel asthma therapies.

Serum Sickness Syndrome Reaction

serum sickness syndrome
Serum sickness syndrome was first recognized in the pre antibiotic era when heterologous antiserum was used as passive immunization for treatment of a number of infectious and toxic illnesses. Today, specific serum therapy with heterologous (usually equine) serum or gamma globulin is restricted to passive immunization for a very few toxic diseases and the use of antilymphocyte (ALG) or antithymocyte (ATG) globulin for immunosuppressive therapy. This is not applicable to active immunization. (more…)

Allergic Reactions

For daily life, of course we need our immune system. Without having immune system, we could not survive long, but there are times when the immune system may harm us rather than helps us. If you suffer from sneezing and stuffy nose, watery eyes, every spring or fall, your doctor may assured your hay fever symptoms. These symptoms are allergic reaction to pollen, dust and spores in the air. (more…)

Food Allergies and Intolerance — Basic Mechanisms

food-allergy-food-intoleranceOur current knowledge for trigger factor and food allergy intolerance is still in it infancy level. We already known that the allergic intolerance are different for groups of people. Some individuals are less resistant in developing allergy than others. Allergic sensitivity or atopic allergic disease are heritable and this means that genetic factors is playing a critical role. But the latest researches reveal that it is not merely heredity factors, environmental also have significant impact for someone to develop allergy.

Allergy trigger in the form of food allergen are mostly fallen to some certain foods like milk, egg, peanuts, fish, soya and nuts. We are curios on what is so peculiar about allergens in food? (more…)

Drug Allergy and Adverse Drug Reactions from Immunologic Basic Perspective

drug allergy drug sensitivity
Drug allergy and adverse drug reactions are common among many people. Those side affect of consuming drugs affecting an about 30% of hospitalized patients. Unintended and undesired reactions of consuming drugs may be immunologic or non immunologic nature. The latter let in drug toxicity, side effects, food intolerance symptoms, and idiosyncratic reactions, popular known as drug allergy. (more…)

Active Immunization and Type of Vaccines

active-immunizationImmunization is needed for person to be prevented of getting diseases, whereas in bigger scale, it is needed to eradicate the break out of diseases in population area. Immunization has accounted for prominent advances in health around the world. Immunizations in children are part of routine health care and it is necessary to do so. Major governments in the world have financed the implementation of vaccines available publicly. Many states in US have laws requiring validation of immunization as a precondition for school entry. Because of this progress, many viruses disease like poliomyelitis, diphtheria, and tetanus have all but disappeared in some developed nations. Some diseases like measles, rubella, and pertussis are still available but rare. World Health Organization has made poliomyelitis disease as the next target for eradication. (more…)

Immunity to Bacteria and How Cellular Immune Response Reacts

immune_bacteriaBacteria cause allergic disease because of toxicity, invasiveness, immunopathology, or lends of these three mechanisms. Thus much of the interaction between a given bacterial species and the cellular immune response can be predicted by considering the immunological mechanisms available in relation to the mechanism of pathogenicity, and the structure of the bacterium. For a toxigenic bacterium, neutralizing antigen & antibody may be all that is needed. Otherwise destruction of the organism itself may be required. (more…)
