[Immunologic tests in patients with idiopathic uveitis--preliminary reports].

AIM
This study aimed to evaluate the immune system function in patients with uveitis of unknown aetiology.


METHODS
The clinical material comprised 19 patients with endogenous uveitis. In all cases the following immunological tests were performed: serum immunoglobulins A, G, M, total IgE, circulating immune complexes, complement components C3c and C4-all determined by laser nephelometry; antinuclear antibodies assessed with indirect immunofluorescence method using HEp-2 cell lines; and antineutrophil cytoplasmic antibodies using indirect immunofluorescence test. In 4 cases lupus anticoagulant was measured with APTT and dRVVT assays.


RESULTS
Among our 19 examined patients immunological abnormalities were found in 12 cases. Changes in immunoglobulin concentrations were found in 8 cases. In 4 patients abnormalities of the complement system were observed. Antinuclear antibodies with speckled pattern in indirect immunofluorescence were present in 7 cases.


CONCLUSION
In a proportion of patients with endogenous uveitis mild immunological abnormalities were present, suggesting an autoimmune background of the disease. Studies of the immunological profile can therefore help in better evaluation of the patients. It remains to be determined whether the observed immunological alterations are of any importance in the pathogenesis of the studied disease.
