Improvement in platelet count after 3rd-line and 4th-line eradication therapy for Helicobacter pylori in patients with immune thrombocytopenia.
Case 1: A 78-year-old woman was diagnosed with H. pylori positive gastritis at a previous hospital in April 2012 and received 3rd-line H. pylori eradication therapy, which ended in failure. She was referred to our department due to oral hemorrhage, petechiae involving all four extremities, and thrombocytopenia in January 2016. She was hospitalized with a diagnosis of ITP and received inpatient treatment. While receiving outpatient prednisolone (PSL) treatment, we administered 4th-line eradication therapy in March. Her platelet levels have since returned to normal, and PSL treatment has been discontinued. She is currently followed without treatment. Case 2: A 65-year-old woman was diagnosed with ITP at a previous hospital in June 2013 and received 2nd-line eradication therapy, which ended in failure. Thereafter, PSL treatment was continued but she was later referred to our department in March 2016. Since 3rd-line eradication therapy was successful, her platelet count normalized and PSL treatment has been discontinued. She is currently followed without treatment. Based on our observations in these two cases, third-line H. pylori eradication therapy is potentially effective in ITP patients.
