Background: Recurrent miscarriage (RM) affects 2-5% of pregnant women. Paternal lymphocyte immunotherapy is a common treatment for RM patients but the outcome has not been consistent. Therefore, combined therapy with other immunosuppressive drugs such as 1 a, 25-dihydroxy-vitamin-D3 (vitamin D3) may improve the outcome. Objectives: To investigate the effect of vitamin D3 on the balance of two essential T cells subsets, T helper (Th) 17 and T regulatory (Treg) cells, which contribute to the immune tolerance during pregnancy. Methods: The expression levels of CD4 and forkhead box protein 3 (FOXP3) in Treg cells, and the expression levels of CD4 and IL- 17 in Th17 cells, were evaluated pre- and 3 months post-immunotherapy in RM patients treated with a combination of paternal lymphocytes and vitamin D3 compared with RM patients receiving lymphocyte immunotherapy alone. Results: Vitamin D3 therapy decreased the frequency of Th17 cells in addition to reducing the Th17/Treg ratio in peripheral blood of RM patients compared with the control group (p <0.05). Conclusion: Considering that RM patients have a higher Th17/Treg ratio in peripheral blood, vitamin D3 may be a candidate therapeutic approach in this disease.

Background: Midkine (MK) is a heparin-binding growth factor with promoting effects in inflammatory responses through enhancing leukocytes migration. Objective: To study the correlation between MK serum levels and concentration of inflammatory cytokines in Multiple Sclerosis (MS) patients. Methods: We evaluated the MK level and its relationship with inflammatory cytokines (IL-17 and IL-23) and antiinflammatory ones (IL-10 and TGF-β) in multiple sclerosis (MS) patients. The serum concentrations of MK and cytokines were assessed by ELISA in 32 MS patients in comparison with 32 healthy subjects. Results: Our data showed that the MK concentration in MS patients is lower than healthy controls (341.15 ± 40.71 Pg/ml vs. 620.15 ± 98.61 Pg/ml, respectively, p=0.015). We also observed a significant decrease in IL-10, IL-23, and TGF-β cytokine levels in MS patients. There was a significant correlation between MK and IL-23 concentrations in our study (r = +0.829, p≤0.001). Conclusion: These results confirm a role for MK in inflammatory reactions in MS.
