Objective: To evaluate the clinical therapeutic effect and security of lymphoplasmapheresis (LPE) for Guillain-Barre syndrome (GBS).
Methods: Sixty-six GBS patients were randomly divided into 2 groups: the therapy group (33 patients) were treated with LPE in addition to the medical treatment; the control group (33 patients) only accepted the medical treatment. The therapeutic effect was evaluated with the initial recovery time of myodynamia and the myodynamia score difference, and the side effect of the therapy group was observed.
Results: The therapy group were treated with LPE for 48 times,1.5 times per person. The average initial recovery time was quicker in the therapy group compared with that in the control group [(6.45+/-3.01) vs (8.36+/-3.83) days]. The difference of limb myodynamia score between pre-treatment and post-treatment in the therapy group was more than that in the control group. The improved number in the therapy group was more than that in the control group, but the ineffective number in the therapy group was not as many as that in the control group. The total effective rate in the therapy group was higher than that in the control group (51.5% vs 27.7%); the average hospital day in the therapy group was shorter than that in the control group [(19.42+/-7.25) vs (24.00+/-8.64) days]; and the difference had statistical significance(P<0.05). The average myodynamia score after the first LPE increased, but the difference had no statistical significance (P>0.05). After the second and the third LPE, the average myodynamia score continued to rise, and the difference had statistical significance (P<0.05). The incidence rate of side effects in the therapy group was 12.5%. Urticaria and hypotension were the major side effects, but they were light and could be relieved by symptomatic treatment.
Conclusion: The therapeutic effect of LPE is definite, and the side effect is scarce. LPE is safe and effective, and it is worth of generalization and applying in clinical practice.
