Antigen non-specific immunological tests in progressive sensorineural hearing loss.

The purpose of the present study was to determine the validity of antigen non-specific immunological tests in order to develop a risk-clinical profile of patients with immune-mediated inner ear pathology. The study was carried out on 38 patients with progressive sensorineural hearing loss and a control group of 26 subjects. Serological testing was used to determine cell activation complexes. In patients with hearing loss, T-lymphocyte subpopulations were found to have an increase in cytotoxic T-cells when compared to T-helper, but only for interleukin-2 receptor expression. This difference was significant between patients and the control group. Present findings suggest that T-lymphocyte "early" marker is of particular interest for developing a risk-clinical profile of patients with sensorineural progressive hearing loss of immune origin.

Immunologic tests in rheumatology.

LEARNING OBJECTIVES: Reading this article will familiarize the reader with the application and interpretation of different autoantibody tests used in rheumatology. DATA SOURCES: Recent rheumatologic textbooks, relevant review articles, and seminal articles in English regarding specific tests. RESULTS: An understanding of this review should enable the reader to approach diagnostic testing systematically in a patient with a suspected connective tissue disease. CONCLUSIONS: The proper use and interpretation of appropriate immunologic tests are important in the diagnosis and treatment of patients with connective tissue diseases.

[Prognostic significance of immunologic tests in cancer of the oral cavity].

An analysis of delayed action cell immunology tests involved 300 patients suffering from stomatological cancers. The tests used, tuberculine, candidine, varidase and DNCB have no particular value as far as discovering the size of the tumour, the quality of eradicating treatment or its progress. On the other hand, bias in the same direction and, even more, variations in the direction of immunity in the course of evolution seem to be a reflection of the patient's immune defence potential. This immune defence potential which can be roughly assessed in this way dose not seem to be reduced by chemotherapy or increased by immunotherapy, at least judging by the criteria used.

Clinical significance of the immunological tests in rheumatoid arthritis.

Of the many theoretical causes of rheumatoid arthritis(RA), the most widely held theory is the autoimmune mechanism. In order to clarify the clinical significance of the immunological tests in RA, we studied immunoglobulin and complement levels in sera and synovial fluids of 118 RA patients and the following results were obtained. 1) The levels of immunoglobulins were elevated in both serum and synovial fluid and this was more prominent in the seropositive cases than the seronegative ones. 2) The levels of C3 component were decreased in both serum and synovial fluid, while those of C4 were decreased only in synovial fluid. Serum C3 and C4 component levels were more decreased in the seropositive cases than the seronegative ones. 3) The immunoglobulin levels in serum (IgG, IgM and IgA) and synovial fluid (IgG and IgA) and the levels of C3, C4 component in serum were well correlated with the clinical forms of rheumatoid arthritis. 4) The IgA level in serum and IgM level in synovial fluid were more increased in the exacerbated cases than the chronic ones. 5) Serum IgG level was decreased after steroid medication over one month.

Chemical and immunological testing for faecel occult blood: a comparison of two tests in symptomatic patients.

An established chemical faecal occult blood test (Haemoccult prepared without rehydration) has been compared with a new immunological test (Hemeselect) in patients referred for investigation of lower gastro-intestinal symptoms. Hemeselect was shown to have a higher sensitivity for colorectal carcinoma (94.0% compared with 58.0%), the greatest difference in sensitivity between the two tests being for rectal cancers. Similarly Hemeselect was more sensitive than Haemoccult for colorectal adenomas (66.6% vs 33.3%), and for inflammatory bowel disease (88.9% vs 33.3%). However the enhanced sensitivity of Hemeselect for colorectal neoplasia and inflammatory bowel disease was accompanied by a significant increase in the overall rate of positive reactions (32.8% of patients had a positive Hemeselect reaction compared with 14.8% who had a positive Haemoccult test), and a reduction in specificity (84.1% for Hemeselect vs 96.0% for Haemoccult). Hemeselect is a more sensitive indicator of colorectal neoplasia in symptomatic subjects, trials of its use as a screening test for asymptomatic neoplasia appear justified.

Nutritional regulation of host resistance and predictive value of immunologic tests in assessment of outcome.

In this review, the authors describe the current information on nutrition modulation of immunity, enumerate the various immunologic tests that are potentially useful in nutritional assessment, examine the reliability of tests predicting disease and complications, and discuss how immunologic evaluation may help in the decision process regarding nutritional support.

[Immunological tests in a follow-up of patients operated on for gastric cancer].

Timely detection of recurrences and adequate therapy thereof together with improvement of methods for multiple-modality treatment may essentially improve remote results of gastric carcinoma treatment. The authors' studies have demonstrated the usefulness of immunologic tests carried out in the postoperative period for the prediction of the results of surgery: these tests are highly informative in the course of a postoperative follow-up.
