From: Cytokine polymorphisms influence treatment outcomes in SLE patients treated with antimalarial drugs
Antimalarial treatment downregulates tumor necrosis factor (TNF)α serum levels in systemic lupus erythematosus (SLE) patients. TNFα serum levels were quantified by ELISA techniques in 171 SLE patients and 215 healthy controls. All patients were classified as users or nonusers of antimalarial drugs during the last three months before sampling. Differences were evaluated by the Mann-Whitney U test.
