Eosinophilia is seen in patients with parasitic infections, various inflammatory and allergic diseases, as well as hematologic malignancies and autoimmune conditions. The bacterial infections as a cause of hypereosinophilia (HE) are rare. In the following article, we report a case of HE with rare etiology. Sixty-six-year-old male, presented with symptomatic thrombocytopenia and pain abdomen of 6 months duration. The evaluation revealed HE on the peripheral blood smear, and bone marrow studies, without atypical cells. During workup for complications, eosinophilic duodenitis was present with a positive rapid urease test, without the involvement of other systems. Etiological workup was negative for other secondary causes of hypereosinophilic syndrome (HES) and immune thrombocytopenia (ITP). The patient responded to anti-Helicobacter pylori treatment, with clinical and hematological improvement. Hence, the final diagnosis of H. pylori-associated HES and secondary ITP was made. The clinicians should bear in mind that H. pylori is an established cause of secondary ITP. However, it has never been reported to cause HES. Anti H. pylori treatment can reverse all the changes without the need for corticosteroids and other therapies. Hence, in an Indian setting, it should always be considered.
