| skin manifestations in parasite infection. | intestinal parasites stimulate ige synthesis by their proteinases. because of their ability to induce ige production and mast cell degranulation (either directly, e.g. ascaris, or via specific ige) it is possible that some parasites induce allergic manifestations. some parasites may be more allergenic than others due to their allergenicity. genetic predisposition, nutritional status, and psychosocial variables of the host and the time and degree of allergen exposure may also play an important ro ... | 2001 | 12561678 |
