The cardinal immunologic changes in sarcoidosis consist of depression of delayed-type hypersensitivity, hyperreactive circulating antibody responses and the Kveim-Siltzbach skin test phenomenon. Depression of delayed-type hypersensitivity is demonstrated by skin tests using tuberculin, mumps, pertussis, trichophytin, oidiomycin, dinitrochlorobenzene and Californian keyhole limpet hemocyanin. The cultured lymphocytes from patients with depression of delayed-type hypersensitivity react poorly to phytohemagglutinin, and there is a close correlation between anergy of lymphocytes in culture and by cutaneous anergy. In vivo cutaneous anergy mirrors in vitro cellular hyporeactivity. Other technics used to expose immunologic defects in peripheral lymphocytes of patients with sarcoidosis include tests of T and B cell function, rosetie formation and migration inhibition. Whereas there is cutaneous anergy and impaired cellular immunity in patients with sarcoidosis, the reverse holds for circulating factors. There are increased circulating immunoglobulin levels, increased circulating antibody levels to Epstein-Barr, herpes simplex, rubella, measles and parainfluenza viruses, increase antibody response to mismatched blood and occasional false-positive Wassermann reactions, but there is no increase in circulating autoan tibodies. There is no evidence that patients with sarcoidosis belong predominantly to any particular histocompatibility locus. Worldwide figures for the Kveim-Siltzbach skin test are presented. They provide evidence of its specificity in various international series. The causes of nonspecific reactions are discussed.

22 patients with Trichophyton rubrum infection were studied for some of their immunological parameters. The trichophytin skin test performed with commercially available Dermatophytin (Hollister-Stier) gave immediate positive reaction in 3 patients. All the other patients gave negative delayed and retarded reactions. In vitro response to PHA of the peripheral lymphocytes was significantly depressed in patients compared to the controls. No relationship could, however, be established between the severity, duration or extent of the disease and the depression of the lymphocyte response. IgG and IfA were found to be within normal limits. IgM levels were significantly depressed which was probably artefactual in nature.

In 27 patients, suffering with chronic alcoholism and hospitalized for pulmonary diseases in the Clinic of Pulmonology and Phthisiology, the following immunological characteristics were checked up: the functional activity of polymorphonuclear leukocytes and in 12 patients also that of alveolar macrophages were evaluated on the basis of the study of the phagocytic index and the phagocytic number, myeloperoxidase and the nitro blue tetrazolium test; the levels of serum IgG, IgA and IgM, the titer of the complement, E-rosette-forming cells (active and total) were also evaluated; the deficiency of cell-mediated immune response was determined by means of intradermal tests with the use of P.P.D., phytohemagglutinin, candidin, trichophytin. In all these investigations the depression of the functional activity of polymorphonuclear leukocytes and alveolar macrophages, dysimmunoglobulinemia, the increased level of circulating immune complexes and the suppression of cell-mediated immunity characteristics were revealed in the patients. Frequent infections and the severe course of bacterial and viral infections observed in such patients can be probably attributed to deficient cell-mediated immune response and to disturbances in phagocytosis.

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.

Delayed hypersensitivity by intracutaneous tests with leishmanin, tuberculin, trichophytin, oidiomycin, as well as sensitization with DNCB were assessed in ten patients with kala-azar. There was a significant depression of delayed hypersensitivity to leishmanin (Montenegro reaction) during the active phase of the disease. The response to ubiquitous microbial antigens and DNCB were also depressed as compared to controls.
