[The interrelationships of allergy, infection and the psyche]

In this review, we would attempt to discuss the interrelationships of allergy, infection, and the psyche. The interplay of these forces is expressed diagrammatically in Fig. 1.1, the interrelationship indicated there, suggests a dynamic interaction between three complex forces, each in itself capable of producing disease. In addition, since each affects the other, each may be able to initiate vicious cycles or chain-type reactions. On the other hand, we would attempt to discuss also, some specific and non-specific mechanisms involved in immunity as well as hypersensitivity reactions against to infectious agents. Fig. 1.2, presents a simplification of the response of allergic patient to microorganisms. Immunity, hypersensitivity and unresponsiveness to different antigens of the same infectious agents can occur simultaneously.
