Lung cancer is one of the leading causes of the cancer death worldwide. Gefitinib is an inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor (EGFR) and has been introduced in the treatment of advanced lung cancers. The responsiveness to gefitinib has been linked to the presence of EGFR mutations. Clinical samples contain many(More)
OBJECTIVE To assess the efficacy and safety of golimumab + methotrexate (MTX) in Japanese patients with active rheumatoid arthritis (RA). METHODS 269 Japanese patients with active RA despite treatment with MTX were randomised (1:1:1) to placebo + MTX (Group 1), golimumab 50 mg + MTX (Group 2) or golimumab 100 mg + MTX (Group 3). Subcutaneous(More)
BACKGROUND COPD is defined by airflow limitation that is not fully reversible and is associated with relevant risk factors. The diagnosis requires that other causes of chronic airflow limitation (CAL) be excluded. We assessed the diagnostic utility of high resolution thoracic CT (HRCT) and bronchodilator reversibility to assist in making a diagnosis of(More)
Gefitinib is an inhibitor of the tyrosine kinase activity of epidermal growth factor receptor (EGFR). Accumulating evidence suggests that gefitinib may provide a survival benefit to EGFR mutation-positive non-small lung cancer patients. We have established a clinical test that can detect EGFR mutations from cytological specimens or paraffin-embedded tissue(More)
CysLT(1) antagonists are effective for a subset of patients with asthma; however, there has been no good way to predict a given patient's response. We examined the interaction between the clinical response to a cysLT(1) antagonist, pranlukast, and DNA sequence variant A(-444)C in leukotriene C(4) synthase (LTC(4) S) gene in Japanese patients with moderate(More)
Mutations in the epidermal growth factor receptor (EGFR) are observed in a fraction of non-small-cell lung cancers (NSCLS). EGFR mutation-positive NSCLS responds to gefitinib. Secondary T790M mutation confers gefitinib resistance to NSCLS. A detection test for the T790M mutation was designed based on the peptide nucleic acid-locked nucleic acid polymerase(More)
Allergic airway inflammation is generally considered a Th2-type immune response. Recent studies, however, demonstrated that Th17-type immune responses also play important roles in this process, especially in the pathogenesis of neutrophilic airway inflammation, a hallmark of severe asthma. We previously reported that dendritic cells release dopamine to(More)
Mucormycosis is an uncommon fungal infection, which generally develops in immunosuppressed hosts. In particular, pulmonary infection by Cunninghamella bertholletiae, a rare species of Mucor, is characterized by invasiveness and high mortality. Herein a case of pulmonary mucormycosis due to C. bertholletiae in a female patient with chronic renal(More)
BACKGROUND Omalizumab, an anti-immunoglobulin E monoclonal antibody, has shown an inhibitory effect on airway inflammation, which may be associated with clinical improvement of severe asthma. This study evaluated changes in airway inflammation and cytokine release by the peripheral blood mononuclear cells (PBMCs) of Japanese patients with severe asthma(More)
