bronchiectasis/tyrosine

We report a case of X-linked agammaglobulinemia who presented with bronchiectasis. The patient had suffered pneumonia about every five years since childhood until he presented to our hospital at age 34 years old. CT showed bronchiectasis predominantly in the right middle lobe, lingula, and lower

Immunoglobulin replacement therapy enhances survival and reduces infection risk in patients with agammaglobulinaemia. We hypothesized that despite regular immunoglobulin therapy, some patients will experience ongoing respiratory infections and develop progressive bronchiectasis with deteriorating

CMCD is a rare congenital disorder characterized by persistent or recurrent skin, nail, and mucosal membrane infections caused by Candida albicans. Heterozygous GOF STAT1 mutations have been shown to confer AD CMCD as a result of impaired dephosphorylation of STAT1. We aimed to identify and

BACKGROUND Hyper-immunoglobulin E recurrent infection syndromes (HIES) has characteristic features and identified mutations. This study investigated clinical features and causal candidate mutations in Taiwanese patients with the HIES phenotype on referral base over 23 million

BACKGROUND X-linked agammaglobulinemia (XLA) is a primary immune deficiency characterized by recurrent bacterial infections and profoundly depressed serum immunoglobulin levels and circulating mature B cells. It is caused by mutations of the Bruton tyrosine kinase (BTK) gene and is the most common

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by a failure to generate immunoglobulins of all isotypes due to the absence of mature B cells and plasma cells, secondary to mutations in the Bruton's tyrosine kinase (Btk) gene. We report six patients with XLA, confirmed

BACKGROUND The efficacy of nintedanib, a multitarget receptor tyrosine kinase inhibitor, has been demonstrated in recent randomized controlled trials involving patients with idiopathic pulmonary fibrosis (IPF). However, accelerated disease progression after nintedanib discontinuation has never been

We report a case of a 58-year-old man suffering from advanced colon cancer with liver metastases. After the sigmoidectomy and left lateral segmentectomy, mFOLFOX6+bevacizumab was initiated. The mFOLFOX6+bevacizumab therapy was performed for 15 courses, but it was stopped because of an increase in

Osimertinib (AZD9291) is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor approved for EGFR-T790M-positive non-small cell lung cancer. A high incidence of interstitial lung disease (ILD) during combination treatment with osimertinib and anti-programmed cell

BACKGROUND X-Linked agammaglobulinemia (XLA) is characterized by an arrest of B cell differentiation, leading to recurrent bacterial infections. Lifelong immunoglobulin replacement therapy (IRT) is indicated to prevent infections and their complications. METHODS A retrospective study of patients

BACKGROUND Hypersecretion of mucin due to goblet cell hyperplasia is frequently encountered in many chronic airway diseases, such as chronic bronchitis, bronchiectasis, bronchial asthma and cystic fibrosis. Even in normal individuals, viral infection or bacterial pneumonia frequently provoke huge

Crizotinib is a tyrosine kinase inhibitor that displays antitumor activity against anaplastic lymphoma kinase (ALK)-positive advanced non-small-cell lung cancer. However, crizotinib-associated interstitial lung disease (ILD) has been reported as an infrequent, but potentially fatal complication. We

Gefitinib (Iressatrade mark) is an epidermal growth factor receptor tyrosine kinase inhibitor that has been approved for the treatment of lung cancer in Japan, however, after marketing several cases of severe pulmonary toxicity were reported. The West Japan Thoracic Oncology Group conducted an

Hypomorphic IL2RG mutations may lead to milder phenotypes than X-SCID, named variably as atypical X-SCID or X-CID. We report an 11-year-old boy with a novel c. 172C>T;p.(Pro58Ser) mutation in IL2RG, presenting with atypical X-SCID phenotype. We also review the growing number of hypomorphic IL2RG

Background: X-linked agammaglobulinemia (XLA) is caused by a mutation of the Bruton's tyrosine kinase (BTK) gene and is the most common genetic mutation in patients with congenital agammaglobulinemia. The aim of this study was to analyze the clinical features, genetic defects, and/or
