ABSTRACT

The author reports his work and other data about the correlation between tuberculosis and leprosy, considered under the immunoallergic, clinic and epidemiologic point of view. 1. Cosidering the immunoallergic correlation between tuberculosis and leprosy with all the data available, he says that in some materials there is an association between positive tuberculin and the positivity of lepromin. There are other elements that reduce the importance of the above mentioned association and of eventual consensibilization. New experiments should be done, especially out of urban areas and in children, in order to comprove that the paralellism of the tuberculin and lepromin curves depends of a relation of cause and effect and not of an association. 2. The researchs of Fernandez, Melson, Hadler and Ziti, and others, favor the hypothesis of transitory tuberculin sensibilization caused by the "M. leprae" and "m. lepraemurium". However, there are many data that reduce its importance. In case it come to be proved in other experiments it wil be difficult to apreciate correctly the correlation between the tuberculin and the lepromin test. When would the first influence to second of vice-versa? and in what degree? Even proved this cross sensibilization from "M. leprae" to "M. tuberculosis", the A. thinks that it would be of slight importance, without interfering largely in the specificity of the tuberculin test. 3. Tuberculosis influencing the clinical course of leprosy and vice versa the author believes that the data are not enough to prove that tuberculosissnakes more favorable the clinical course of leprosy and vice versa. 4. Tuberculosis influencing the epidemiology of leprosy and vice versa the author considers the Chaussinand's hypothesis that the erradication of leprosy in Europe was chiefly determined by presence of tuberculosis among the people.
