BACKGROUND: Interstitial lung disease (ILD) can be a severe extra-articular disease manifestation in Rheumatoid Arthritis (RA). A potential role of fibrocytes in RA associated ILD (RA-ILD) has not previously been described. We present a modified faster method for measuring circulating fibrocytes, without intracellular staining. The results are compared to the traditional culture method, where the number of monocytes that differentiate into mature fibrocytes in vitro are counted. The results are following compared to disease activity in patients with severe asthma, ILD, RA (without diagnosed ILD) and RA with verified ILD (RA-ILD)...

OBJECTIVES: To describe diffusing capacity for carbon monoxide (DLCO) and its components, that is, membrane diffusing capacity (DmCO) and pulmonary capillary blood volume (Vc) in children with Crohn's disease (CD), and to investigate the correlation between these parameters and disease activity. WORKING HYPOTHESIS: The most common lung function abnormalities are a reduced pulmonary DLCO and small airways disorders which are in many instances, clinically silent. No valid explanations have been proposed regarding the modifications in gas transfer capacity in active CD...

A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings...

BACKGROUND AND OBJECTIVE: To determine whether computer-based quantification (CALIPER software) is superior to visual computed tomography (CT) scoring in the identification of CT patterns indicative of restrictive and obstructive functional indices in hypersensitivity pneumonitis (HP). METHODS: A total of 135 consecutive HP patients had CT parenchymal patterns evaluated quantitatively by both visual scoring and CALIPER. Results were evaluated against: forced vital capacity (FVC), total lung capacity (TLC), diffusing capacity for carbon monoxide (DLCO ) and a composite physiological index (CPI) to identify which CT scoring method better correlated with functional indices...

Patients with idiopathic pulmonary arterial hypertension (IPAH) and a reduced diffusion capacity of the lung for carbon monoxide (DLCO) have a worse survival compared to IPAH patients with a preserved DLCO. Whether this poor survival can be explained by unresponsiveness to pulmonary hypertension (PH)-specific vasodilatory therapy is unknown. Therefore, the aim of this study was to evaluate the hemodynamic and cardiac response to PH-specific vasodilatory therapy in patients with IPAH and a reduced DLCO. Retrospectively, we studied treatment naïve hereditary and IPAH patients diagnosed between January 1990 and May 2015 at the VU University Medical Center...

OBJECTIVES: Nintedanib is a tyrosine kinase inhibitor approved for the treatment of idiopathic pulmonary fibrosis (IPF). The pathological pathways involved in fibrogenesis in IPF and interstitial lung disease associated with systemic sclerosis (SSc-ILD) show commonalities; both involve fibroblast activation, myofibroblast accumulation and deposition of extracellular matrix. The SENSCIS™ trial is a randomised, placebo-controlled Phase III trial that will evaluate the efficacy and safety of nintedanib in patients with SSc-ILD (NCT02597933)...

RATIONALE AND OBJECTIVES: Thoracic x-ray computed tomography (CT) and hyperpolarized (3)He magnetic resonance imaging (MRI) provide quantitative measurements of airspace enlargement in patients with emphysema. For patients with panlobular emphysema due to alpha-1 antitrypsin deficiency (AATD), sensitive biomarkers of disease progression and response to therapy have been difficult to develop and exploit, especially those biomarkers that correlate with outcomes like quality of life. Here, our objective was to generate and compare CT and diffusion-weighted inhaled-gas MRI measurements of emphysema including apparent diffusion coefficient (ADC) and MRI-derived mean linear intercept (Lm) in patients with AATD, chronic obstructive pulmonary disease (COPD) ex-smokers, and elderly never-smokers...

BACKGROUND: This study was conducted to assess associations of pleural plaques (PP) and longitudinal lung function in vermiculite miners of Libby, Montana who are occupationally exposed to asbestos. High-resolution computed tomography (HRCT) was used to identify asbestos-related findings in former Libby vermiculite miners. We investigated annual lung function decline in miners with PP only and compared them to miners with normal HRCT findings. MATERIALS AND METHODS: HRCTs from 128 miners were categorized into the following 4 diagnostic groups: (1) normal computed tomography scan (n = 9); (2) PP only (n = 72); (3) PP and interstitial fibrosis (n = 26) and (4) additional HRCT abnormalities (n = 21) such as rounded atelectasis, diffuse pleural thickening, pleural effusions or pulmonary nodules or tumor >1cm in diameter...

Ofatumumab is an anti-CD20 humanized monoclonal antibody utilized in the treatment of several clinical conditions resistant to other treatments. In spite there was a general expectation that ofatumumab was less toxic compared to rituximab, side effects have been reported that resemble those of its anti-CD20 chimeric precursor. Here, we describe the first case of Ofatumumab associate lung injury occurring in a 14-year-old boy affected by nephrotic syndrome dependent to prednisone plus cyclosporine A who had been treated with the dose of drug utilized in nephrotic syndrome (1500 mg/173 m(2))...

Radiation-induced lung injuries mainly include the (acute or sub-acute) radiation pneumonitis, the lung fibrosis and the bronchiolitis obliterans organizing pneumonia (BOOP). The present review aims at describing the diagnostic process, the current physiopathological knowledge, and the available (non dosimetric) preventive and curative treatments. Radiation-induced lung injury is a diagnosis of exclusion, since clinical, radiological, or biological pathognomonic evidences do not exist. Investigations should necessarily include a thoracic high resolution CT-scan and lung function tests with a diffusing capacity of the lung for carbon monoxide...
