BACKGROUND: Despite the relationship of idiopathic pulmonary fibrosis (IPF) with advancing age, little is known about the epidemiology of interstitial lung diseases (ILD) in the elderly. Here we describe the diagnoses, clinical characteristics, and outcomes of patients who were elderly at the time of ILD diagnosis. METHODS: Among subjects from a prospective cohort study of ILD, elderly was defined as age > 70. Diagnoses were derived from a multi-disciplinary review...

YKL-40, a chitinase-like protein mainly secreted by macrophages, neutrophils and epithelial cells, is increased in patients with idiopathic interstitial pneumonia and sarcoidosis. We aimed to investigate the role of YKL-40 as a biomarker in hypersensitivity pneumonitis (HP).72 HP patients, 100 interstitial lung disease (ILD) controls and 60 healthy controls were studied. YKL-40 was measured by ELISA in serum and bronchoalveolar lavage fluid (BALF) at baseline and follow-up. The relationship between YKL-40 levels, clinical variables and disease outcome was evaluated...

Background The bronchoalveolar lavage (BAL) cellular analysis is an invasive method of exploration of the lung. Its diagnostic value in interstitial lung disease (ILD) is integrated to a multi-disciplianry approach implicating clinicians, radiologists and pathologists. Aim We targeted to evaluate the diagnostic value of the BAL. Methods We reported a retrospective study about patients hospitalized for an ILD since the 1st January 2011 to the 31th December 2013. Thirty three patients were admitted in the Department of Pulmonology and the BAL analyses were studied in the Department of Pathology of the same hospital...

BACKGROUND: Bronchoalveolar mesenchymal stem cells (MSCs) play an important role in the maintenance of lung integrity. Therapeutic application of bone marrow-derived MSCs reduced chronic bronchial inflammation in idiopathic pulmonary fibrosis, and improved the ratio of survivors in sepsis with pneumonia. This study investigated the effect of MSCs from bronchoalveolar lavage fluid (BALF) of hypersensitivity pneumonitis (HP) on T-cell function under in vitro conditions. METHODS: Bronchoalveolar MSCs were obtained via bronchoscopy with BAL from children with severe subacute HP...

Idiopathic interstitial pneumonias comprise 8 clinicopathological entities, most of them with a chronic course and various prognosis. Idiopathic pulmonary fibrosis is the most frequent and most severe of these. Computed tomography has an important role for its diagnosis. It can identify the corresponding pathological pattern of usual interstitial pneumonia in about 50 percent of cases. It can suggest differential diagnosis in other cases, most frequently fibrosing nonspecific interstitial pneumonia and chronic hypersensitivity pneumonitis...

A 61-year-old man was evaluated for a 2 month history of cough and dyspnea without relevant exposures other than pyrethrin containing insecticidal sprays he used while grooming dogs almost daily. High Resolution Computed Tomography (HRCT) of the chest demonstrated a Non-Specific Interstitial Pneumonia (NSIP) pattern. Pulmonary function testing revealed an isolated mildly reduced diffusion capacity. Bronchoalveolar lavage (BAL) results confirmed the presence of foamy histiocytes, lymphocytes, and polymorphonuclear cells consistent with ongoing exposure...

Eosinophilic myocarditis (EM) is a rare and potentially fatal disease if left untreated. Because the disease can have a delayed presentation and can appear even after 2 years, its underlying causes often remain unknown. We report the case of a 63-year-old man with an atypical clinical presentation of hypersensitive EM and significant coronary artery disease, which was confirmed through coronary angiography. The patient was treated with hydrochlorothiazide (12.5 mg once daily for 2 years) and budesonide/formoterol (160/4...

BACKGROUND: Diagnostic evaluation of patients with diffuse parenchymal lung disease (DPLD) is best achieved by a multidisciplinary team correlating clinical, radiologic, and pathologic features. Surgical lung biopsies remain the gold standard for histopathologic diagnosis of idiopathic interstitial pneumonias. Emerging data suggest an increasing role for transbronchial cryobiopsy (TBC) in DPLD evaluation. We describe our experience with TBC in patients with DPLD. METHODS: We retrospectively reviewed medical records of patients with radiographic features of DPLD who underwent TBC at Mayo Clinic, Rochester, Minnesota in June 2013-September 2015...

Context .- Idiopathic pulmonary fibrosis (IPF) is a distinctive clinicopathologic entity and the most common form of progressive diffuse lung scarring in older adults. Idiopathic pulmonary fibrosis manifests histopathologically as the usual interstitial pneumonia pattern. The usual interstitial pneumonia pattern is distinguished by geographically and temporally heterogeneous fibrosis that is peripherally accentuated, often with honeycombing and traction bronchiectasis. Idiopathic pulmonary fibrosis is not the only disease that leads to end-stage lung fibrosis, however, and several other entities may also cause advanced fibrosis...

The role of bronchoalveolar lavage fluid (BALf) examination in differential diagnosis of interstitial lung diseases (ILD) was established. Currently, functional polarization into M1 (pro-inflammatory) and M2 (anti-inflammatory) subpopulations is emphasized. The aim of our study was to compare the proportion of M1 and M2 in BALf of patients with different ILD. BALf samples were collected from 75 ILD patients: sarcoidosis (SA, 36), hypersensitivity pneumonitis (HP, 10), non-specific interstitial pneumonia (NSIP, 8), idiopathic pulmonary fibrosis (IPF, 6) and other ILD (15)...

BACKGROUND: Multidisciplinary concertation is mandatory in order to assess interstitial pneumonias. The study of the bronchoalveolar lavage helps evoking a diagnosis according to the lavage profile. In lymphocytic alveolitis, immunocytochemistry or in flux cytometry are necessary in order to identify the different clusters of lymphocytes implicated. AIM: Our objective was to evaluate the profile of 31 lymphocytic alveolitis using 2 different techniques which are the immunocytochemistry and the in flow cytometry in order to evaluate the efficacy of each technique and to compare the different results to the final diagnoses...

Allergic bronchopulmonary aspergillosis (ABPA) results from a hypersensitivity response to airways colonization with Aspergillus fumigatus, and it occurs most often in individuals with asthma or cystic fibrosis. Allergic bronchopulmonary aspergillosis is an indolent, but potentially progressive, disease in patients. In patients infected with human immunodeficiency virus (HIV), ABPA is rare, and its description in the literature is limited to case reports. We describe the occurrence of ABPA in a 37-year-old woman with well controlled HIV infection...

Bird fancier's lung (BFL), also called bird-breeder's lung or pigeon-breeder's disease (PBD), is a hypersensitivity pneumonitis (HP) that is rare in children. A 9-year-old male patient complained of cough, dyspnea and chest pain, in his examination his lips were cyanosed and his SaO2 was 86% at room air. Bilateral crepitant rales and sibilant rhochi were also detected. In his thoracic computerized tomography, the ground glass areas were noted in both lungs. In his medical history, it was discovered that he lived above an office in which birds and bird manure were merchandised...

A 57-year-old male was diagnosed with mycobacterium tuberculoma and was treated with isoniazid, rifampicin, ethambutol, and pyrazinamide. Three weeks after initiation of treatment, he presented with fever and appetite loss. Chest radiograph showed diffuse micronodular shadows on both lung fields. High-resolution chest computed tomography findings were diffuse parenchymal micronodules in both lungs, which was consistent with hypersensitivity pneumonia. Because drug-induced pneumonia was suspected, the antituberculous regimen was discontinued...

Mycoplasma pneumoniae is one of the most common causes of community-acquired pneumonia in children and young adults. The incidence of fulminant M. pneumoniae pneumonia (MPP) is relatively rare despite the high prevalence of M. pneumoniae infection. This literature review highlights the clinical features of fulminant MPP by examining the most recent data in epidemiology, clinical presentation, pathogenesis, and treatment. Fulminant MPP accounts for 0.5-2% of all MPP cases and primarily affects young adults with no underlying disease...

Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group...

Bacterial protein synthesis is the target for numerous natural and synthetic antibacterial agents. We have developed a poly(U) mRNA-directed aminoacylation/translation (A/T) protein synthesis system composed of phenylalanyl-tRNA synthetases (PheRS), ribosomes, and ribosomal factors from Pseudomonas aeruginosa This system has been used for high-throughput screening of a natural-compound library. Assays were developed for each component of the system to ascertain the specific target of inhibitory compounds. In high-throughput screens, 13 compounds were identified that inhibit protein synthesis with 50% inhibitory concentrations ranging from 0...
