Efficacy of helicobacter pylori eradication as an upfront treatment of secondary immune thrombocytopenia: an experience from Pakistan.
The effect of Helicobacter-pylori eradication therapy on the platelet counts in patients with immune thrombocytopenia is still debatable. The aim of this study was to assess the response rates of standard triple eradication therapy in secondary immune thrombocytopenia with Helicobacter pylori infection.



From January 2012 to December 2013, 197 patients were diagnosed to have immune thrombocytopenia, out of which 22(11.1%) patients infected with Helicobacter- Pylorus were enrolled in this study. Helicobacter-Pylori infection was documented by Helicobacter-pylori stool antigen enzyme immunoassay method. All positive patients were put on triple eradication therapy. The responses rates to treatment were defined as per International Working Group on ITP.



Mean age of patients was 43.18±12.5 years. There were 10(45.5%) males and 12 (54.5%) females. Of the 22 patients, 7(31.8%) exhibited a complete response (CR) to Hpylori eradication therapy; 10(45.4%) attained a response; and 5(22.7%) had no response. Mean base line platelet counts were 53.36±24.5x109/l, while platelet counts at 4 week following eradication was 80.86±51.0x109/l (P=0.003). The predictive factor of response following eradication therapy was baseline platelet counts. Virtually all responders had baseline platelet counts >30x109/l and all non-responders had <30x109/l of platelet counts.



Though the prevalence of H-pylori is low, this study confirmed the efficacy of eradication in increasing the platelet counts in H-pylori positive patients with ITP. It is an important measure in short time, safe and very cost effective to achieve platelets increment. We endorse the routine detection and eradication treatment of H-pylori infective ITP patients.
