OBJECTIVE: To investigate the effect of thymopentin 5 (TP5) combined with immunosuppressive agents in treatment of relapse after extended thymectomy in patients with myasthenia gravis (MG).
METHODS: One hundred thirty-five MG patients who were to undergo extended thymectomy, 62 adults and 73 children, were randomly assigned to 2 groups: non-TP5 group (n = 60) treated with intramuscular injection of prednisone + pyridostigmine daily for 3 months as a basic treatment, and TP5 group (n = 73), treated with prednisone + pyridostigmine + TP5 for 3 months. Follow-up was conducted for more than 1 year.
RESULTS: The remission rates of children in the TP5 group at different time points were all markedly higher than those in the non-TP5 group, and the remission rates of children in the TP5 group during the period of 2 months to 2 years after thymectomy were all significantly higher (all P < 0.05). And the remission rates of the adults of the TP5 group during the period of 6 months to 2 years after thymectomy were all significantly higher than those of the non-TP5 group (all P < 0.05). In the pediatric cases the withdrawal rate of the TP5 group was significantly higher, and the relapse rate was significantly lower than those of the non-TP5 group. No side effect developed during the follow-up.
CONCLUSION: TP5 is effective in reducing relapse and has a higher drug withdrawal rate, especially among children.
