Assessment of interferon production in patients with chronic nonviral diseases by whole blood or whole bone marrow techniques.
Hundred and fifty-four samples of heparinized blood from patients with chronic toxoplasmosis, chronic brucellosis, lung diseases, psychiatric affective disorders, healthy individuals and neonates, were obtained. The experimental material included also 14 bone marrow samples from patients with hematological diseases or lung cancer. The whole cell populations were treated with several classical IFN inducers and supernatants were assayed for IFN activity in human lung adenocarcinoma cell line A 549 using VSV or EMC viruses as challenge. The response of WBC to NDV or PHA + PMA was high and remarkably stable in majority of cases except listed below. The levels of IFN induced by LPS were low. The response of WBMC to IFN inducers closely resembled the response of WBC. Low IFN levels in samples of stimulated WBMC from some hematological patients were connected with low cellularity. WBC from psychiatric patients with affective disorders weakly responded to stimulation with NDV. This suggested an existence of deficiency of IFN alpha production connected with affective disorders. Also WBC from cord blood failed to react to PHA + PMA and were poorly responsive to NDV.
