CONTEXT The advent of molecular tools capable of subclassifying eosinophilia has changed the diagnostic and clinical approach to what was classically called hypereosinophilic syndrome. OBJECTIVES To review the etiologies of eosinophilia and to describe the current diagnostic approach to this abnormality. DATA SOURCES Literature review. CONCLUSION Eosinophilia is a common, hematologic abno...

background: allergic diseases have increased during the past decade worldwide. th2 type lymphocyte response is known to play an important role in the process of allergic inflammation. il-4, a mediator of type ii cytokine response increases ige synthesis and interferon gamma, a cytokine of type i response interferes with il-4 and inhibits ige production. selenium is an essential component of glu...

BACKGROUND Eosinophilia in children is commonly caused by or parasitic, allergic and immunologic problems. OBJECTIVES To study clinical and laboratory profile of patients with eosinophilia and to identify possible causes. METHOD A prospective and descriptive study was conducted from January 2009- December 2011. All the cases of eosinophilia with symptoms and signs of single or multiple orga...

Background.  This study examines the predictive value of eosinophilia for Strongyloides stercoralis infection, as measured by enzyme-linked immunosorbent assay (ELISA) testing, in an endemic community. In remote communities, eosinophilia is frequently used as a proxy test for the presence of helminth infections. Past studies of eosinophilia and Strongyloides infection have been conducted in spe...

STUDY OBJECTIVE The study aimed to determine the prevalence and incidence of pulmonary eosinophilia, with special reference to tropical pulmonary eosinophilia, in a rural community. DESIGN This was a five year prospective study from 1981-86. SETTING The study was conducted in four villages of Tamil Nadu in south India. SUBJECTS The study population consisted of 24,950 subjects.

churg-strauss syndrome (css) is a small vessel granulomatous vasculitis that characteristically affects the middle age group and is extremely rare in children. we describe an 8-year-old girl with a prolonged history of cough and eosinophilia that initially was labeled as pulmonary tuberculosis, but after complementary assays, associated with skin biopsy, eosinophilic fibrinoid vasculitis, css w...

a 7 year-old male presented with recurrent fever, cough and respiratory distress for over last 2 years. based on extremely high eosinophil count, high immunoglobulin e, increase in eosinophilic precursors in bone marrow, and positive antigen test for wuchereria bancrofti, a diagnosis of tropical pulmonary eosinophilia with eosinophilic leukemoid reaction was made. complete recovery was achieved...

Nonspecific airway hyperresponsiveness (AHR) is a hallmark of human asthma. Both airway eosinophilia and high serum levels of total and antigen-specific immunoglobulin E (IgE) are associated with AHR. It is unclear, however, whether either eosinophilia or increased IgE levels contribute directly to, or predict, the development of AHR. Investigations conducted with various murine models of asthm...

thyroid tumors producing colony-stimulating factors associated with neutrophilia and/or eosinophilia are very rare and almost all of them concern anaplastic thyroid cancer. Only one case of papillary thyroid carcinoma associated with neutrophilia and one case of medullary thyroid carcinoma associated with eosinophilia have been reported. In this report a 72-year old male patient with metastatic...
