Comparison of the oxidative stress status of children with ITP in two therapies using methylprednisolone and methylprednisolone along with IVIG

Background: Idiopathic thrombocytopenic purpura (ITP) is a rare and autoimmune disorder determined by an abnormal reduction in the number of platelets. The current study aims to evaluate the oxidative stress status of children with ITP in two treatment methods using methylprednisolone and methylprednisolone with intravenous immunoglobulin (IVIG). Materials and Methods: This retrospective study was conducted on 60 children with ITP who referred to Baghaei Hospital in Ahvaz in 2021.  All the ITP children were equally divided into two groups, 30 receiving methylprednisolone and 30 receiving methylprednisolone and IVIG. The sampling of the patients’ blood was done in two stages before and after the start of treatment. Then, malondialdehyde (MDA), superoxide dismutase (SOD), total antioxidant status (TAS), total oxidative status (TOS), catalase (CAT) and glutathione were measured according to the instructions in the commercial kit. The analyses were performed using SPSS software version 23. P value 0.05 was significant. Results: The number of platelets after treatment in methylprednisolone and methylprednisolone+ IVIG groups was 133.44 ± 18.93 and 158.76 ± 34.76 (×103/µL), respectively. Itas significantly increased compared to that before the treatment (P = 0.04). The amount of TAC in the group receiving methylprednisolone + IVIG and the methylprednisolone group was 1.64 ± 0.18 and 1.26 ± 0.53 nm, respectively; there was a remarkable difference between the two groups (P = 0.001). Also, SOD, CAT and glutathione in the methylprednisolone + IVIG group were remarkably higher than those in the methylprednisolone group (P 0.05). Finally, the levels of TOS were lower in the methylprednisolone + IVIG group (19.74 ± 9.93 μmol) than in the methylprednisolone group (26.65 ± 10.64 μmol) (P = 0.01). Conclusion: A combination of IVIG and methylprednisolone was found to have a greater effect on improving antioxidant status and decreasing the oxidative stress indices of ITP children.
