Objective: To determine the response to IV anti-D and its comparison with splenectomy as second line therapy in refractory and relapsed cases of ITP, in the Aga Khan University Hospital, Karachi.
Methods: A total of 23 patients with chronic ITP were treated with either anti-D or splenectomy as second line treatment. The patients were assessed for time to achieve a response to second line treatment, duration ofresponse and adverse events.
Results: There were 12 patients in the anti-D group and 11 in the splenectomy group. The mean platelet count at presentation was 9,000/cumm. The mean age was 8.9 years and 13.0 years and the male to female ratio was 1:1 and 1:1.2 in anti-D and splenectomy group respectively. 54.5% of the patient in the anti-D group responded compared to 81.8% in the splenectomy group. Median time to achieve a response was 7 days in the anti-D group and 1 day in the splenectomy group. Mean time to relapse was 87.8 days in the anti-D group and 55.4 days in the splenectomy group. No adverse events were recorded for any of the infusions of anti-D and none of the patients had more than 0.5 gm /dl fall in the hemoglobin level following anti-D infusion.
Conclusion: It was thus concluded that Anti-D is a relatively safe, convenient and effective therapy for chronic ITP and can be used as a splenectomy sparing agent when treatment is clinically indicated.
