Abstract:
Objective: To observe the efficacy of rhIL-11 for the chemotherapy-induced thrombocytopenia and to evaluate adverse events and safety of rhIL-11 in vivo. Methods: A total of 55 patients with blood platelet count 50×10
9/L after chemotherapy were randomly assigned to 2 treatment groups. rhIL-11 was given in group A and was not given in group B. Results: The platelet counts of group A on day 2 to day 21 was significantly higher than that in group B on day 4 to day 21. The durations of Ⅱ, Ⅲ and Ⅳ grade thrombocytopenia were 3.0, 3.2 and 0.4 days in group A, meanwhile the durations were 5.1, 5.8 and 2.2 days in group B. The toxicity and side effects of rhIL-11 included: palpitation, cardiac arrhythmia, edema, fever, joint and muscle pain, skin eruption, Headache, dizzy and inertia. No serious adverse event occurred. Conclusions: rhIL-11 is a safe and effective drug for patients with chemotherapy-induced thrombocytopenia via stimulation of the thrombocyte proliferation.
