Abstract
OBJECTIVE
We aimed to investigate the expression of interleukin 12 (IL-12) family cytokines (IL-12, IL-23, IL-27 and IL-35) and their relevant cytokines (IFN-γ, IL-4, IL-17A and IL-10) in patients with chronic immune thrombocytopenia (cITP) as well as the effect of high-dose dexamethasone (HD-DXM) treatment on this expression.
MATERIALS AND METHODS
DXM was administered orally at a dose of 40 mg per day for 4 consecutive days to 38 patients with cITP. We measured the plasma levels of IL-12p70, IL-23, IL-27, IFN-γ, IL-4 and IL-17A before and after treatment and also in 36 matched healthy controls, by means of FlowCytomix™ technology. The plasma levels of IL-10 and IL-35 were measured by enzyme-linked immunosorbent assay.
RESULTS
Significantly higher plasma levels of IL-12p70, IL-23, IL-27, IFN-γ and IL-17A were observed in cITP patients than in controls (p < 0.01), and after HD-DXM treatment, these levels decreased significantly (p < 0.01). However, significantly lower plasma levels of IL-4, IL-10 and IL-35 were observed in cITP patients than in controls (p < 0.01); after the HD-DXM treatment, these levels had increased significantly in the cITP patients (p < 0.01). Moreover, the cytokine levels of patients who attained a complete response returned to the levels of normal controls (p > 0.05) but were not corrected in the patients who had no response (p < 0.01).
CONCLUSIONS
The patients with cITP had abnormal expression of the IL-12 family cytokines and their relevant cytokines levels, and HD-DXM treatment corrected the derangement of plasma cytokines. Measuring cytokine levels may help in the clinical assessment of cITP.
