Common variable immunodeficiency (CVID) is the most common severe adult primary immunodeficiency and is characterized by a failure to produce antibodies leading to recurrent predominantly sinopulmonary infections. Improvements in the prevention and treatment of infection with immunoglobulin replacement and antibiotics have resulted in malignancy, autoimmune, inflammatory and lymphoproliferative disorders emerging as major clinical challenges in the management of patients who have CVID. In a proportion of CVID patients, inflammation manifests as granulomas that frequently involve the lungs, lymph nodes, spleen and liver and may affect almost any organ...

Visceral leishmaniasis (VL) is associated with interstitial pneumonitis according to histology and radiology reports. However, studies to address the functional impact on respiratory function in patients are lacking. We assessed pulmonary function using noninvasive spirometry in a cross-sectional study of hospitalized adult VL patients from Minas Gerais, Brazil, without unrelated lung conditions or acute infections. Lung conditions were graded as normal, restrictive, obstructive, or mixed patterns, according to Brazilian consensus standards for spirometry...

BACKGROUND: Azathioprine is a commonly prescribed therapy for connective tissue disease-associated interstitial lung disease (CTD-ILD). Combination therapy that included azathioprine was recently shown to increase the risk of death and hospitalization in patients with idiopathic pulmonary fibrosis. Whether azathioprine increases the risk of adverse outcomes in patients with fibrotic CTD-ILD, including those with CTD-associated usual interstitial pneumonia (UIP), remains unknown. METHODS: A retrospective cohort analysis was performed to determine the combined incidence rate of death, transplant and respiratory hospitalization associated with azathioprine exposure...

Advances in the treatment of idiopathic interstitial pneumonia (IIP) represent an urgent, unmet medical need for patients with this category of diffuse parenchymal lung disease. IIPs involve varying combinations of fibrosis and inflammation of unknown cause and may be associated with pulmonary hypertension (PH). When it occurs, PH is associated with higher oxygen needs, greater functional impairment, and increased mortality. However, whether or when PH is a maladaptive versus adaptive phenomenon remains to be determined...

Idiopathic pulmonary fibrosis (IPF) is a form of progressive interstitial lung disease with unknown etiology. Due to a lack of effective treatment, IPF is associated with a high mortality rate. The hallmark feature of this disease is the accumulation of activated myofibroblasts that excessively deposit extracellular matrix proteins, thus compromising lung architecture and function and hindering gas exchange. Here we investigated the origin of activated myofibroblasts and the molecular mechanisms governing fibrosis formation and resolution...

The purpose of this study was to investigate the characteristics of primary Sjögren's syndrome (pSS) patients with IgG4 positive (IgG4(+)) plasma cell infiltration in labial salivary glands (LSGs). Paraffin sections of LSGs from 336 pSS patients were stained with IgG4 and IgG monoclonal antibodies. According to the infiltration of IgG4(+) plasma cells, patients were divided and clinical and serological characteristics were analyzed and compared. Based on the infiltration of IgG4(+) plasma cells in the LSGs, patients were divided into three subgroups, low IgG4, moderate IgG4, and high IgG4 groups...

Clinical assessment and workup of patients referred to cardiologists may need an extension to chest disease. This requires more in-depth examination of respiratory co-morbidities due to uncertainty or severity of the clinical presentation. The filter and integration of ecg and echocardiographic information, addressing to the clues of right ventricular impairment, pulmonary embolism and pulmonary hypertension, and other less frequent conditions, such as congenital, inherited and systemic disease, usually allow more timely diagnosis and therapeutic choice...

As the Japanese organ donor allocation system does not permit the allocation of lungs at a priority level to patients on extracorporeal membrane oxygenation (ECMO), many of these patients die before suitable donor lungs become available. We report our first experience with ECMO as a bridge to lung transplantation (LTx) from a brain-dead donor. A 40-year-old man with interstitial lung disease who was listed for LTx 3 years previously, experienced progressive deterioration of respiratory function. He was mechanically ventilated at another hospital and was transported to our hospital due to severe hypoxemia...

BACKGROUND: The treatment of chronic hypersensitivity pneumonitis (cHP) often includes systemic oral corticosteroids, but the optimal pharmacologic management remains unclear. The morbidity associated with prednisone has motivated the search for alternative therapies. We aimed to determine the effect of treatment with mycophenolate mofetil (MMF) or azathioprine (AZA) on lung function in patients with cHP. METHODS: Patients with cHP treated with either MMF or AZA were retrospectively identified from four interstitial lung disease centers...

Carbon nanotubes (CNTs) are newly developed materials with unique properties and a range of industrial and commercial applications. A rapid expansion in the production of CNT materials may increase the risk of human exposure to CNTs. Studies in rodents have shown that certain forms of CNTs are potent fibrogenic inducers in the lungs to cause interstitial, bronchial, and pleural fibrosis characterized by the excessive deposition of collagen fibers and the scarring of involved tissues. The cellular and molecular basis underlying the fibrotic response to CNT exposure remains poorly understood...

STAT proteins are a family of transcription factors that mediate cellular response to cytokines and growth factors. Study of patients with familial susceptibility to pathogens and/or autoimmune diseases has led to the identification of 7 inherited disorders that are caused by mutations of 4 STAT family genes. Homozygous or compound heterozygous mutations of STAT1 lead to complete or partial forms of STAT1 deficiency that are associated with susceptibility to intracellular pathogens and herpetic infections. Patients with heterozygous STAT1 gain-of-function (GOF) mutations usually present with chronic mucocutaneous candidiasis (CMC) but may also experience bacterial and viral infections, autoimmune manifestations, lymphopenia, cerebral aneurysms, and increased risk to develop tumors...

Both common and rare variants contribute to the genetic architecture of pulmonary fibrosis. Genome-wide association studies have identified common variants, or those with a minor allele frequency of >5%, that are linked to pulmonary fibrosis. The most widely replicated variant (rs35705950) is located in the promoter region of the MUC5B gene and has been strongly associated with idiopathic pulmonary fibrosis (IPF) and familial interstitial pneumonia (FIP) across multiple different cohorts. However, many more common variants have been identified with disease risk and in aggregate account for approximately one-third of the risk of IPF...
