Most initial infections are local, i.e. the infectious agent gains entry to the body at a single site, e.g. via an insect bite or infection of a particular mucosal surface. The next stages of infection involve pathogens multiplication and pathogens spread. These can be considered part of the lifestyle of the pathogen, and infectious organisms vary enormously in lifestyle. Multiplication of pathogens provides variety at three levels: the mode of multiplication, the site of replication and the rate of multiplication. (more…)

Allergic rhinitis is a very common problem associated with poor quality of life, reductions in social and work activities and poor interpersonal relationships. The main goal of the management of allergic rhinitis is to improve the quality of life. Immunotherapy is a specific therapy for allergic rhinitis and several reports have documented the safety and efficacy of this treatment . Safety has been a key issue in immunotherapy and various modalities are being investigated to make allergy immunotherapy more tolerable and safe to administer. (more…)

The potency of an allergen vaccine is the total allergen activity (that is, the sum of the contribution to allergenic activity from any individual IgE molecule specific for any t-cell epitopes on any molecule in the allergen vaccine). It follows that potency measures always will depend on the serum pool or patient panel selected as well as the methodology used. Methods used for the assessment of allergen vaccine potency may be divided into in vitro or in vivo techniques. (more…)

Being an immunological disease, the characteristics of allergy are those of specificity and memory. Regardless of whether the clinical manifestation is rhinoconjunctivitis, rhinitis, or asthma, the underlying immunological response disorder is based on the adverse reactions of cells in the immune system upon contact with allergens. These cells are specific for epitopes that are structural parts of allergens present in the allergenic source material. Two types of cells (i.e., T cells and B-cells) produce receptor molecules (i.e., T-cell receptors and immunoglobulin [IgE] antibodies) that, through high-affinity interactions with the allergen, efficiently catalyze the presence of even minute amounts of allergens into clinical symptoms, the extreme consequence of which may be life-threatening to the patient.

The production of allergen vaccines imposes a number of constraints on both the selection of source materials and the physicochemical conditions used during the extraction procedure. The process must neither denature the proteins (allergens) nor alter their composition significantly, including the quantitative ratio between the individual components. (more…)

Mold is a fungus type and different from plants, animals and bacteria. Molds are kind of decomposers of dead organic matter such as leaves, wood and plants. Mold can sometimes infect living plants and animals. Spores and organs such as human hair is the favorite of the mold colonies, but are too small for us to see without a microscope. If a large amount of mold growing on the surface, often appears black or green. The rust color is affected by nutrient source and age of the colony. If mold is growing behind your home wallpaper, colorful pink may appear or purple spots. (more…)

Having determined an adequate potency and complexity in composition, an allergen vaccine may still be deficient in the content of major allergen. Only a few manufacturers of allergen vaccines have acknowledged the importance of controlling individual allergens in the vaccines, but the principle is gaining more acceptance among control authorities and clinicians, both in Europe and in the United States.

The quality of an allergen vaccine is a measure of the complexity of the composition, including the concentration of the various constituents. That is, the presence or absence of individual constituents determines the quality. Only selected constituents (i.e., the major allergens or other marker proteins) can be quantified independently. The complexity of the composition of allergen vaccines can be assessed by several techniques. These are standard separation techniques in biochemistry and traditional immunochemistry. (more…)

If you suspect that certain foods trigger wheezing or asthma symptoms in your child, your first action should be a consultation with your pediatrician to determine the exact inventory of foods your child is allergies to. The doctor will probably refer you to a pediatric allergist, or may carry out the tests him-or herself to identify your child’s reactive foods. (more…)
