Primary immunodeficiencies occur with a frequency approaching that of cystic fibrosis (1:2500 live births). However, because they are perceived to be very rare and usually present with common infections, they are under-diagnosed. Often the diagnosis is not considered until substantial end-organ damage has occurred, by which time definitive treatment is only partially successful in preventing further infections. (more…)

The molecular basis of Common Variable Immunodeficiency (CVID) is unknown and the diagnosis requires the exclusion of other diseases known to cause primary antibody deficiency syndromes, such as X-linked lymphoproliferative disease (XLP). XLP is a rare primary immunodeficiency disease in which severe immune dysregulatory phenomena occur, typically after exposure to Epstein–Barr virus (EBV). The defective gene in XLP is SAP (SLAM associated protein, where SLAM is signalling lymphocyte activation molecule), a small SH2 domain containing protein involved in signal transduction events downstream of the SLAM family of receptors.

Egg allergy is likely more of interest to parents, parents who have children that must be vaccinated. This concern is because many vaccines are made from chicken eggs. It is common that many people are having allergies or reactions to vaccines that are made by egg. There are some symptoms or reaction can cause redness around the vaccination site like a skin rash.

Patients (and many doctors) frequently use the term ‘allergy’ when referring to any adverse drug reaction, even one that has no features of an IgE-mediated allergy response. However, IgE-mediated allergy explains only about 10% of all adverse reactions to antigen antibody reactions from antibiotics. Patients who have experienced unexplained symptoms during treatment with two or more antibiotics are often said to have ‘multiple antibiotic allergy’; using this definition, the description can be applied to one patient in every 22.

Of the several species of Haemophilus that are known, Haemophilus influenzae is the most prevalent pathogen. Several distinct capsular serotypes have been defined, but type b H influenzae is responsible for most clinical disease. H influenzae is a respiratory pathogen that colonizes the oropharynx and causes bronchitis, pneumonia, or disseminated infection when local or systemic host defense factors are compromised. (more…)

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…)

Allergies refers to an exaggerated reaction by our healthy immune system in response to bodily contact with certain foreign substances. These foreign substances are usually harmless. But, in a person whose body is prone to allergies, these foreign substances are recognized by the body and one part of the immune system is turned on. Allergy-producing substances are called as ‘allergens‘. Examples include pollens, dust mite, molds, danders, and certain foods. (more…)

Asthma is a disease marked by wheezing, coughing, and difficulty in breathing. It is a form of allergy, a physical reaction of some persons to substances that are harmless to other people. An asthma patient becomes short of breath during asthma attacks. The lining of the nasal passages swells, and spasms occur in the bronchial muscles.
Substances that cause asthma or other allergies are called allergens. Allergens may be taken into the body by being inhaled or swallowed. (more…)

Bacteria 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…)
