ABSTRACT: Laboratory and clinical data provide evidence that a biological linkage exists between asthma and depression. Cytokines are key molecules in both diseases. They promote allergic reaction as well as depressive symptomatology. Antidepressants may have a therapeutic role in asthma by suppressing production of proinflammatory cytokines, inducing production of anti-inflammatory ones and preventing their brain effects. Most antidepressants also induce adaptive changes in central monoaminergic neurotransmission, which itself might modulate immune reactivity and central actions of cytokines. Antidepressants may also have direct effects on the immune cells. Their impact on hypothalamus-pituitary-adrenal axis is discussed. Antidepressants are expected to terminate the cascade of inflammatory events in other inflammatory diseases as well. The use of antidepressants in experimental clinical trials in patients with asthma is suggested.

ABSTRACT: In contrast to Geschwind, Behan and Galaburda (GBG) theory, there is strong evidence that inheritance through maternal line is responsible for the coexistence of asthma and left-handedness early in childhood. A new model that incorporates GBG's theory and maternal inheritance is proposed. This hypothesis suggests that maternal atopy is the most important factor in the evolution of asthma and that GBG's theory applies mainly in childhood. An inherited enhanced sensitivity of fetus to testosterone may be the underlying mechanism that leads to the development of bronchial asthma.
