Abstract
Production of cytokines in unstimulated and mitogen-stimulated cultures were evaluated by ELISPOT in 34 SLE patients with low to moderate disease activity and 23 healthy controls. Significantly reduced production of IFNγ, IL4 and IL12 and significantly increased production of IL6, IL10 and TNFα were found in patients with SLE. Regression analysis revealed that production of all six cytokines tended to decrease with increasing disease activity, but negative correlation with SLEDAI was significant (p < 0.05) only for PHA-stimulated IL4, unstimulated and PHA-stimulated IL10 and SAC-stimulated IL6. Negative correlation of stimulated and unstimulated IL6 and TNFα production with anti-DNA antibody levels were also significant.
