Which condition from the list below exemplifies a type III hypersensitivity reaction?
Immune complex deposition mediates a type III hypersensitivity reaction. Auto-antibody complexes are generated in lupus and are then deposited in various tissues, including the kidneys, skin, and joints. Although they are examples of type II reactions, Graves disease and myasthenia gravis are classified as type V reactions in some classification schemes. In Graves, the thyroid's TSH receptors are targeted by auto-antibodies, whereas in Myasthenia, the acetylcholine receptor is the target. Due to the fact that T lymphocytes are directed against thyroid antigens and antibodies are also generated, Hashimoto's thyroiditis is typically seen as an illustration of a combination of type II and IV reactions. A typical instance of a type I, IgE mediated reaction is allergic rhinitis.
Which of the following is a valproic acid side effect?
One of the most severe side effects that Valproic acid might have is pancreatitis. Phenytoin can have a side effect called gingival hyperplasia. Zonisamide or topiramate may have the negative effects of causing kidney stones or weight loss.
