Hypersensitivity pneumonitis

Takashi Ishiguro, Shoko Kawai, Ayako Kojima, Yoshihiko Shimizu, Katsuhiko Kamei, Noboru Takayanagi
Koji is a fermenting agent used in many traditional Japanese foods , and Aspergillus oryzae is the most frequently used microorganism in koji production. Few cases of hypersensitivity pneumonitis due to A. oryzae have been reported. However, physicians should recognize the disease because of the increasing globalization of food production.

Chronic active Epstein-Barr virus (CAEBV) infection is a rare disease with high mortality. Most of CAEBV patients have been reported from Japan and are pediatric cases.The goal was to describe the clinical characteristics and the immunophenotypic features of peripheral lymphocytes in adult onset CAEBV patients.We retrospectively reviewed and analyzed all adult onset CAEBV cases admitted to Peking Union Medical College Hospital (PUMCH) between 2012 and 2016. Demographic, clinical, laboratory data, and the immunophentyping data of peripheral lymphocytes were collected...

Fungal bioaerosols are ubiquitous in the environment and human exposure can result in a variety of health effects ranging from systemic, subcutaneous, and cutaneous infections to respiratory morbidity including allergy, asthma, and hypersensitivity pneumonitis. Recent research has focused on the role of microRNAs (miRNAs) following fungal exposure and is overlooked, yet important, group of regulators capable of influencing fungal immune responses through a variety of cellular mechanisms. These small non-coding ribose nucleic acids function to regulate gene expression at the post-transcriptional level and have been shown to participate in multiple disease pathways including cancer, heart disease, apoptosis, as well as immune responses to microbial hazards and occupational allergens...

A 47-year old man presented to our hospital with a 6-month history of malaise, cough and dyspnea on exertion. Laboratory testing revealed the severe hyponatremia. A chest X-ray showed bilateral diffuse micronodules. Anti-Trichosporon asahii antibody and environmental provocation test were positive. Bronchoalveolar lavage fluid showed lymphocytosis and low CD4/8 ratio. The specimens obtained by transbronchial lung biopsy revealed alveolitis. Based on these findings, the patient was diagnosed as having summer-type hypersensitivity pneumonitis (SHP)...

Children's interstitial lung diseases (chILD) are increasingly recognised and contain many lung developmental and genetic disorders not yet identified in adult pneumology. Worldwide, several registers have been established. The Australasian Registry Network for Orphan Lung Disease (ARNOLD) has identified problems in estimating rare disease prevalence; focusing on chILD in immunocompetent patients, a period prevalence of 1.5 cases per million children and a mortality rate of 7% were determined. The chILD-EU register highlighted the workload to be covered per patient included and provided protocols for diagnosis and initial treatment, similar to the United States chILD network...

BACKGROUND: The spectrum of interstitial lung diseases (ILDs) have mainly been reported from the developed countries; data from developing countries is sparse and conflicting. The aim of this study is to describe the distribution of various ILDs from a developing country. METHODS: This is an analysis of prospectively collected clinical, radiological and histological data of consecutive subjects (age >12 years) with ILDs from a single tertiary care medical center...

This study analyzed the Type 1 and Type 2T helper (Th-1/Th-2) cytokines (including interleukins), immune cellular, matrix profile and pathogens in granulomas with unexplained etiology and compared to infectious and non-infectious etiology. Surgical lung biopsies from 108 patients were retrospectively reviewed. Histochemistry, immunohistochemistry, immunofluorescence, morphometry and polymerase chain reaction (PCR) were employed, respectively, to evaluate total collagen and elastin fibers, collagen I and III, immune cells, cytokines, metalloproteinase-9 (MMP-9), myofibroblasts and multiple usual and unusual pathogens...

A 52-year-old man developed interstitial pneumonitis during treatment with desvenlafaxine for major depressive disorder. The man received desvenlafaxine at 50 mg for symptoms of depression 4 years earlier. Six months after a dose increase to 100 mg, he developed bronchitic symptoms with mild, persistent dyspnea. Investigations revealed a restrictive pattern on pulmonary function testing, bilateral upper lobe reticular opacities with traction bronchiectasis on radiology imaging, and end-stage interstitial fibrosis with honeycomb changes consistent with chronic hypersensitivity pneumonitis on open lung biopsy...

Pulmonary fibrosis is not uncommon. Usual interstitial pneumonitis (UIP)/idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic pulmonary fibrotic diseases and has the worst prognosis with a mean life expectancy of 3.8 years. The American Thoracic Society has provided guidelines for the accurate diagnosis of IPF.In 2014, 2 antifibrotic medications were approved in the United States that target the multiple fibrotic pathways of UIP, which increased the need for early and accurate diagnosis of IPF...

A 62-year old man was admitted to our hospital with a 2-week complaint of a dry cough, general fatigue, and dyspnea on effort. He has been an onion farmer for several years and developed these symptoms after cleaning up onion peels with air compressors. A chest roentgenogram and computed tomography showed a ground glass shadow in the bilateral upper lung field. Cellular analysis of the bronchoalveolar lavage fluid showed elevated total cell numbers and lymphocytes. Transbronchial lung biopsies revealed a non-caseating granuloma with both epithelioid cells and Langhans giant cells...

We report two family members, a 64-year-old woman (patient 1) and her 37-year-old son (patient 2) diagnosed with summer-type hypersensitivity pneumonitis (SHP). Both patients had high serum titers of anti-Trichosporon asahii antibody. The patients lived in the same house and worked in the same barbershop. Patient 1 was diagnosed with SHP in the summer, and she reacted positively to the provocation test at the work place, but not in the house. Patient 2 was diagnosed with SHP in the winter. Generally, SHP develops and is diagnosed in the summer...

RATIONALE: Hypersensitivity pneumonitis is a complex lung disease resulting from repeated inhalation of a variety of antigens. Limited data exist regarding its epidemiology. OBJECTIVE: To describe the trends in the annual incidence and prevalence of hypersensitivity pneumonitis in the US. METHODS: We developed novel claims-based coding algorithms to identify hypersensitivity pneumonitis, chronic hypersensitivity pneumonitis, and fibrotic hypersensitivity pneumonitis cases using the 2004-2013 MarketScan Commercial and Medicare Supplemental healthcare claims databases...

Solid tumors involving glandular organs express mucin glycoprotein which is eventually shed into the circulation. As aresult these proteins can easily be measured in the serum and be used as potential tumor markers. The most commonly used tumor markers for breast cancer are CA 27-29 and CA 15-3, which both measure the glycoprotein product of the mucin-1 (MUC1) gene. CA 27-29 has been approved by the US Food and Drug Administration for monitoring disease activity in breast cancer patients. Most oncology clinical practice guidelines do not recommend the use of tumor markers for routine surveillance of early stage disease but recognize their utility in the metastatic setting...

In a series of nine patients with histopathological diagnosis of hypersensitivity pneumonitis, we retrospectively evaluated clinical data, exposure related factors, pulmonary function tests and chest computed tomography scans. A restrictive abnormality with reduction of diffusion capacity for carbon monoxide was mainly found. Chest scans showed fibrotic patterns in most cases; ground glass attenuation areas with mosaic pattern and consolidation in the rest. Exposure to avian antigens, cereal grains and air conditioners contaminated with fungi yeasts and bacteria, were suspected from clinical data in two-thirds of the cases...

Interstitial lung diseases (ILDs) form one of the most fascinating fields in pulmonary medicine. They also pose one of the greatest challenges for accurate diagnosis and proper treatment. Even within the recommended and warranted multidisciplinary approach, differentiating between one disease and another may lead to frustration, especially when proper lung tissue is not available for adequate pathological review. A surgical lung biopsy (SLB) might render enough tissue for histopathology, but this could come at the expense of high morbidity and even mortality, as in the case of usual interstitial pneumonia (UIP)...
