Explain the antibody reactions of agglutination?

Explain the antibody reactions of agglutination?

Antibody tests: Latex beads are coated with an antigen. You you have antibodies against that antigen, your serum may agglutinate the beads. A titer can be determined by diluting the serum. Sometimes, a high titer may not agglutinate until the serum is diluted (prozone effect). ...Read more

Are hypersensitivity reactions are caused by the cross linking of antibodies?

Are hypersensitivity reactions are caused by the cross linking of antibodies?

On the cell surface.: Ige mediated allergic reactions involve 2 ige antibodies directed against the same allergens in close proximetry on the surface of mast cells or basophils. The antibody then fits in between the 2 ige antibodies. That activates the cell to release mediators (chemicals) that directly or indirectly by activating other cells resulting in allergy symptoms. The ige antibodies themselves do'nt cross link. ...Read more

If you have anti-saccharomyces cerivisiae antibodies (asca), can u have negative reactions to foods/drinks containing this beneficial yeast?

Antibodies : Yes but be careful. High amounts of this antibody are found with celiac disease, chrone's disease and a few other disorders. It is not an allergic antibody but rather indicates antibody against mannan in the outer coating of this form of yeast. Cross reactions with other yeasts including candida can occur. ...Read more

What would cause severe reactions(fatigue, inflammation)to many foods when you do not have any antibodies against any foods? Mastocytosis? Crohn's?

What would cause severe reactions(fatigue, inflammation)to many foods when you do not have any antibodies against any foods?  Mastocytosis?  Crohn's?

Celiac disease?: Good morning: many patients mean different scenario when they say reaction. If it is general discomfort it may or may not be due to allergy. For nonspecific symptoms we need to rule out celiac disease. There are different antibodies; ige related to allergy and igg related to inflammation. There are tests to make a diagnosis ordered by a physician. Avoiding gluten may be worth a try. ...Read more

Are allergic reactions common to antibiotics?

Are allergic reactions common to antibiotics?

Yes: Statistically the penicillin family of antibiotics trigger the most reactions because they are so universally used. Penicillin testing is widely available by allergists and is recommended to avoid needlessly avoiding this inexpensive and effective family of antibiotics. But any kind of antibiotic carries with it the chance of allergy, and as a class, is one of the most common drug causing allergy. ...Read more

When in the course of taking an antibiotic are the severe allergic reactions most likely to occur ? What about mild allergic reactions?

When in the course of taking an antibiotic are the severe allergic reactions most likely to occur ? What about mild allergic reactions?

Variable: Highly variable and depends on the type of reaction. If you are already allergic then the most severe reaction can happen right away. Some reactions can appear after a few doses and some may even occur after completion. There are also non allergic side effects that can occur anytime. ...Read more

Anaphylactic allergic reactions due to antibiotics. How do I recover from the lingering side-effects?

Anaphylactic allergic reactions due to antibiotics. How do I recover from the lingering side-effects?

Systemic steroids: If you have delayed side effects that are significant, you may benefit from a course of systemic steroids such as Medrol (methylprednisolone) or prednisone. I would discuss this with your doctor. ...Read more

What is the safest antibiotic that has the least side effects, allergic reactions, and potential to damage organs like the liver?

What is the safest antibiotic that has the least side effects, allergic reactions, and potential to damage organs like the liver?

Depends: The commonly used antibiotics do not cause organ damage but the dose may need be adjusted if the particular organ has been impaired. There is no drug (or food) which is 100% safe but generally speaking those in the macrolide group (Z pak (azithromycin) etc) have the lowest side effect profile even though erythromycin may cause GI upset in a small % of people. ...Read more

Are there some antibiotics without adverse drug reactions?

Are there some antibiotics without adverse drug reactions?

No such animal: Any and all drugs have the potential to cause adverse drug reaction. This does not mean everyone is going to get every potential adverse reaction, just that something bad can happen to anyone. Even sugar pill (placebo) causes adverse drug reaction. Our brain is a powerfully imaginative organ. ...Read more
