The clinical effect of Prednisone in combination with Mycophenolate mofetil on idiopathic thrombocytopenic purpura (ITP) and its influence on the level of peripheral blood T lymphocytes and NK lymphocytes

Abstract

Objective: To explore he curative effect and safety of Prednisone in combination with Mycophenolate in treating ITP and its influence on the level of peripheral blood T lymphocytes and NK lymphocytes. Method: 93 cases of ITP patients were divided into the observation group and the control group by the Random Number Table method, 48 cases for the observation group, 45 for another. Patients in the control group orally took 0.5 mg/kg Prednisone Acetate tablets daily, two times each in the morning and evening. And the observation group, based on the treatment of the control group, orally took Mycophenolate Mofetil Dispersible tablets twice a day, 1 g each time. According to patients’ conditions, 3 to 5 courses were set for treatment with 3 weeks a course. Compared PLT amount and the changing situation of inflammatory factors, CD3+ and CD3+CD95L+ before and after the treatment, the level of CD3+Caspase-3+ and CD3+Caspase-8+, NK+, NK+ CD95L+, NK+Caspase-3+, NK+Caspase-8, the curative effect and adverse events. Result: After treatment, PLT amount in both groups increased, and the increase in the observation group was much higher than that of the control group, the difference had statistical significance (P < 0.05). The time needed for PLT amount in the control group to reach the normal and peak values was longer than that of the observation group, whose PLT peak value was higher than another group. The difference had statistical significance (P < 0.05). After the treatment, the levels of TNF-α and IL-6 were lowered, and the value of the observation group was lower than that of another. The difference between and within the group has statistical significance. After the treatment, the level of CD3+, CD3+CD95L+ and CD3+Caspase-8+ is much higher and CD3+Caspase-3+ level lower than that before the treatment. The difference has statistical significance (P < 0.05). After the treatment, the level of NK+ and NK+ CD95L+ is higher and the level of NK+Caspase-8+ lower than that before the treatment. The difference has statistical significance (P < 0.05). After the treatment, the total effective rate 91.67% of the observation group is much higher than that 75.56% of another. The difference has statistical significance (P < 0.05). After the treatment, the incidence rate of adverse events in the control group is 11.11% (5/45), while 4.17% (2/48) in the observation group. The difference between groups has statistical significance (χ2 = 3.890, P < 0.05). Conclusion: The curative effect of Prednisone in combination with Mycophenolate on ITP patients is better than orally taking Prednisone tablets. Moreover, when it comes to Prednisone in combination with Mycophenolate, both the PLT amount and immunocompetence are improved without much adverse reaction, and the molecules of peripheral blood T lymphocytes and NK lymphocytes can be effectively adjusted to relieve the symptoms. So the method is trustworthy to be popularized for clinical practices. Keywords: Prednisone, Mycophenolate, ITP, T lymphocyte, NK lymphocyte
