ACR SLE classification criteria in 2012. 1 clinical and 1 immunologic criterion. ANA titers, additional testing is indicated. The CBC count may help screen for leukopenia, lymphopenia, anemia, and thrombocytopenia. Urinalysis and creatinine studies may be useful to screen for kidney disease.
Levels of inflammatory markers, including the ESR and CRP, may be elevated in any inflammatory condition, including SLE. CRP levels change more acutely, and the ESR lags behind disease changes. In addition, some patients have congenital complement deficiency that predisposes them to SLE. Creatine kinase levels may be elevated in myositis or overlap syndromes. Autoantibody tests Table 3, below, summarizes the autoantibody tests that are used in the diagnosis of SLE.
Il lupus eritematoso sistemico è una malattia considerata incurabile, the onset of SLE could be attributed to the elevated hydroxylation of estrogen and the abnormally decreased levels of androgens in females.
