[Behavior of delayed-type hypersensitivity in parapsoriasis].
The authors present a study of behaviour of the late hypersensitivity in fourteen patients carrying parapsoriasis with age varying from 36 to 64 years being nine men and five women with time of the illness development from one to eleven years. There were thirteen white sick people and a yellow one. The parapsoriasis diagnosis was confirmed in all of them clinica and histopathologica. The patients were not getting any therapeutic with corticosteroids or immunosuppressive drugs at the time of study. They were studied immunological through methods in vivo. 1. Methods in vivo. a) Intradermoreactions with the infectious antigens: PPD, trichophytin, levedurin, E. coli. It was used as a control group of fourty normal fellows. b) Sensibility to DNCB. The results obtained allow the following thesis: 1. Low table of positivity to the intradermal reactions to the late reading only one of the antigens tested on the patients (E. coli) related to the others. According to these elements we cannot get at a conclusion for depression of the inespecific cellular immunity in our sick patients. 2. Significant statistics difference on the sensibility test to DNCB on the sick patients related to the controls, a fact which shows a certain degree of the depression of the inespecific cellular immunity. 3. The sick patients with parapsoriasis before taking some treatment should go through the study of a late hypersensitivity.
