This study evaluated the changes in intracellular cytokine expression patterns in different T-lymphocyte subsets after ozone therapy in patients with refractory idiopathic granulomatous mastitis (IGM). The results showed that ozone therapy stimulated a specific immune response in T cells and downregulated the expression of TGF-β in regulatory T cells. These immune system changes can improve wound healing and restore immune dysfunction in patients with refractory IGM.
Immunological dysfunction has been suggested to play a major role in the pathogenesis of idiopathic granulomatous mastitis (IGM). We recently showed that ozone therapy was effective in patients with steroid-resistant IGM. This study assessed alterations in intracellular cytokine expression patterns in different T-lymphocyte subsets after ozone therapy in refractory IGM. Peripheral blood T lymphocyte subsets (CD8(+), CD4(+), CD4(+)CD25(+) CD127(-)) were analyzed via flow-cytometry for intracellular cytokine expressions IFN-gamma, TNF-alpha, IL-10, and TGF-beta before and after completion of 4-month systemic ozone therapy. Ozone therapy significantly increased the CD4(+)IFN-gamma(+) (p = 0.032), CD4(+)TNF-alpha(+) (p = 0.028), and the CD8(+) TNF-alpha(+) (p =0.012) T cells. In contrast, significant decreases in CD4(+) IL-10(+) (p = 0.047) and CD8(+)IL-10(+) T cells (p = 0.022) and CD4(+)CD25(+) CD127(-//low) Treg cells secreting TGF-beta (p = 0.005) were found after ozone therapy. When patients were analyzed according to the response to ozone therapy, patients with a complete remission were more likely to have increased CD3(-)CD16(+)CD56(+) natural killer cells (p = 0.0027) and decreased CD19(+)B lymphocytes (p = 0.046) following ozone therapy. Our results suggest that ozone therapy stimulated a T-helper-1 response associated with IFN-gamma production and downregulation of TGF-beta expression in CD4(+)CD25(+)CD127(-) Treg cells. These alterations in the immune system following ozone therapy can improve wound healing and restore immune dysfunction in patients with refractory IGM.
