BACKGROUND The A to C transversion in the promoter region of the gene encoding leukotriene C4 synthase (LTC4S) is proposed to be associated with the development of aspirin-induced asthma (AIA). OBJECTIVE We investigated the frequency of the polymorphism in Japanese population and its association with clinical characteristics and cysteinyl leukotriene(More)
In this study, Norovirus (NV) capsid gene was detected from patients of gastroenteritis, domestic sewage, treated wastewater, river water and cultivated oysters in geographically close areas where all of samples were collected. In order to improve recovery efficiency of NVs from oysters, a new method using a spallation apparatus was developed. As a result,(More)
A 53-year-old man who had been suffering from asthma presented to our hospital because of abnormal shadows detected on a chest X-ray film during a routine medical examination. A biopsy specimen of a mucus plug obtained by bronchoscopy showed fungal hyphae, eosinophils, and Charcot-Leyden crystals, with evidence of lung tissue eosinophilia. Schizophyllum(More)
BACKGROUND Limited information is available regarding the clinical usefulness of measuring the levels of IgE to allergen components from house dust mites (HDMs) in the diagnosis of genuine HDM allergy. METHODS To evaluate the diagnostic usefulness of measuring levels of serum IgE antibodies (Abs) to allergen components from Dermatophagoides pteronyssinus(More)
PURPOSE This study was designed to clarify the definition of sick house syndrome (SHS). METHODS SHS was defined based on the disease related to habitation as follows. 1. The cause of the onset of a disease relates to house. 2. Symptoms appear within house. 3. Symptoms will be less serious or disappear if patient away from house. 4. If patient goes into(More)
OBJECTIVE We studied the effects of intravenous immunoglobulin (IVIG) treatment on clinical symptoms and regulatory T (Treg) cell frequency in patients with eosinophilic granulomatosis with polyangiitis (EGPA). METHODS Twenty-two EGPA patients with severe mononeuritis multiplex or cardiac dysfunction received IVIG therapy combined with conventional(More)
Churg-Strauss syndrome (CSS) is characterized by the presence of asthma, eosinophilia, and small-vessel vasculitis with granuloma. It is a distinct entity, as determined from all classifications of systemic vasculitis. The poor prognostic factors in CSS are renal insufficiency, cardiomyopathy, severe gastrointestinal (GI) tract, and central nervous systems(More)
Churg-Strauss syndrome (CSS) is an uncommon systemic vasculitis with an increase in the number of eosinophils in the peripheral blood and tissues. Its pathogenesis is unknown, and there is no evidence that genetic factors influence susceptibility to this disease. We present a case of familial CSS in two sisters with atopic-type bronchial asthma and negative(More)
BACKGROUND Chronic eosinophilic pneumonia (CEP) with asthma precedes the onset of Churg-Strauss syndrome (CSS) in half of all patients with CSS. It is not known what determines whether patients with CEP after asthma will have CSS. OBJECTIVE We examined whether activation of regulatory T cells in patients with CEP inhibits CSS development and is otherwise(More)
