Correlation between the results of the migration inhibitory factor production test with DNA and the severity of the disease in the systemic lupus erythematosus patients.

A correlation was made between the severity of clinical symptoms of SLE and the results of the migration inhibitory factor (MIF) production test. For this purpose 10 patients with various manifestations of SLE were examined by MIF production test before and after the immunosuppressive therapy. A good correlation between the actual clinical stage and the results of the MIF production test was found. The successful immunosuppressive therapy turned the positive MIF production into the negative one in most of the observed patients. The MIF production test is therefore recommended as a good complementary test for the estimation of the actual state of the SLE.
