BACKGROUND AND OBJECTIVE: Interstitial lung disease (ILD) is a common pulmonary manifestation of systemic sclerosis (SSc). It is unknown whether radiographic fibrosis score predicts mortality in SSc-associated ILD (SSc-ILD). We retrospectively analysed patients with SSc-ILD to evaluate whether radiographic fibrosis score was a useful predictor of mortality. METHODS: We identified SSc-ILD patients evaluated at Kurashiki Central Hospital (Japan) from 2006 to 2016, and radiographic fibrosis scores based on the extent of reticulation and honeycombing on high-resolution computed tomography (HRCT) scanning were calculated by manually tracing around each fibrotic area...

BACKGROUND: Interstitial pneumonia with autoimmune features (IPAF) identifies a recently recognized autoimmune syndrome characterized by interstitial lung disease and autoantibodies positivity, but absence of a specific connective tissue disease diagnosis or alternative etiology. We retrospectively reviewed the clinical presentation, diagnostic workup and management of seven critically ill patients who met diagnostic criteria for IPAF. We compared baseline characteristics and clinical outcome of IPAF patients with those of the population of ARDS patients admitted in the same period...

This manuscript describes an outbreak of fatal toxoplasmosis in wallabies. Ten adult red necked wallabies (Macropus rufogriseus) were imported from New Zealand to the Virginia Zoo. Agglutination testing upon admission into quarantine showed all animals to be negative for antibodies to Toxoplasma gondii. Nine of these wallabies died from acute toxoplasmosis within 59-565 (average 224) days after being moved onto exhibit. Clinical signs included lethargy, diarrhea, tachypnea, and ataxia that progressed rapidly; death without premonitory signs occurred in one case...

A 10-year-old male castrated red kangaroo (Macropus rufus) presented with mandibular swelling. Examination findings included pitting edema with no dental disease evident on examination or radiographs. The results of blood work were moderate azotemia, hypoalbuminemia, and severely elevated urine protein:creatinine ratio (9.9). Radiographs showed an interstitial pattern of the caudal right lung, and an abdominal ultrasound demonstrated scant effusion. Symptomatic and empirical therapy with antibiotics, anti-inflammatory drugs, and an angiotensin-converting enzyme (ACE) inhibitor did not resolve clinical signs...

In common variable immunodeficiency, lung manifestations are related to different mechanisms: recurrent pneumonias due to encapsulated bacteria responsible for diffuse bronchiectasis, diffuse infiltrative pneumonia with various patterns, and lymphomas, mostly B cell extranodal non-Hodgkin type. The diagnosis relies on significant serum Ig deficiency and the exclusion of any primary or secondary cause. Histopathology may be needed. Immunoglobulin (IgG) replacement is crucial to prevent infections and bronchiectasis...

PURPOSE: Secondary spontaneous pneumothorax (SSP) is difficult to treat by itself and due to its association with serious underlying diseases. It has a high rate of recurrence and often requires extended hospitalization. Therefore, we evaluated the outcome and risk factors associated with recurrence and extended hospitalization. METHODS: We retrospectively examined 61 patients with SSP, and evaluated the patients' characteristics, underlying diseases, introduction of home oxygen therapy, Brinkman index, and X-ray imaging findings to determine the risk factors for recurrence and extended hospitalization...

BACKGROUND: Chlamydia pneumonia is reported to account for a relatively large number of cases of CAP. In elderly patients in particular, the clinical presentation can be a severe form of diffuse interstitial pneumonia. The chest X-ray presentation is aspecific. Lung US can show a typical pattern of diffuse interstitial lung syndrome; in some cases, like the present one, the association of multiple B lines with a coarse and thickened pleural line points to a more likely diagnosis of interstitial pneumonia...

The MUC5B promoter polymorphism (rs35705950) has been associated with interstitial lung abnormalities (ILA) in white participants from the general population; whether these findings are replicated and influenced by the ILA subtype is not known. We evaluated the associations between the MUC5B genotype and ILA in cohorts with extensive imaging characterisation.We performed ILA phenotyping and MUC5B promoter genotyping in 5308 and 9292 participants from the AGES-Reykjavik and COPDGene cohorts, respectively.We found that ILA was present in 7% of participants from the AGES-Reykjavik, 8% of non-Hispanic white participants from COPDGene and 7% of African-American participants from COPDGene...

Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are two of the most important pathogens affecting the swine industry worldwide. Co-infections are common on a global scale, resulting in pork production losses through reducing weight gain and causing respiratory disease in growing pigs. Our initial work demonstrated that the fecal microbiome was associated with clinical outcome of pigs 70days post-infection (dpi) with PRRSV and PCV2. However, it remained uncertain if microbiome characteristics could predispose response to viral infection...

Porcine reproductive and respiratory syndrome virus (PRRSV) is an important pathogen that causes huge economic losses to the swine industry worldwide. In this study, a type 2 PRRSV strain was isolated from primary porcine alveolar macrophage cells and designated as GD1404. Interestingly, this strain was unable to grow in MARC-145 cells. Analysis of the full-length genome sequence revealed that strain GD1404 was an inter-subgenotype recombinant of strains QYYZ and JXA1. The C-terminus of the GP2 protein of strain GD1404 had an amino acid deletion...

BACKGROUND: Regulatory T cells (Tregs) are crucial in maintaining immune tolerance and immune homeostasis, but their role in idiopathic pulmonary fibrosis (IPF) is unclear. This study was designed to explore the role of Tregs in IPF. METHODS: Percentages of Tregs and their subpopulations in peripheral blood (PB) and bronchoalveolar lavage (BAL) samples were determined by flow cytometry in 29 patients with IPF, 19 patients with primary Sjögren's syndrome-related interstitial pneumonia (pSS-IP), and 23 healthy controls (HCs)...

BACKGROUND: Little is known about the epidemiology of interstitial lung disease (ILD) amongst Canada's Indigenous populations. Clinicians working in Eeyou Istchee (the Cree territory of the James Bay region of Québec, population 17, 956) suspected that ILD was more common in this area. We sought to identify all prevalent and incident cases of ILD in Eeyou Istchee between 2006 and 2013, to describe characteristics of affected patients, distribution of subtypes, and estimate disease incidence...

A computer-aided differential diagnosis (CADD) system that distinguishes between usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP) using high-resolution computed tomography (HRCT) images was developed, and its results compared against the decision of a radiologist. Six local interstitial lung disease patterns in the images were determined, and 900 typical regions of interest were marked by an experienced radiologist. A support vector machine classifier was used to train and label the regions of interest of the lung parenchyma based on the texture and shape characteristics...

Acute fibrinous and organising pneumonia (AFOP) is a rare histological pattern of interstitial lung disease. The authors describe a 60-year-old woman admitted to the hospital for sustained fever, presenting with an alveolar opacity on chest X-ray, with the presumed diagnosis of community-acquired pneumonia and the onset of antibiotics. Since serological results suggested that Legionella pneumophila was the infectious agent, she was discharged on levofloxacin. A week later, she was again admitted with fever...

BACKGROUND: Late-onset noninfectious pulmonary complications (LONIPCs), which occur more than 3 months after allogeneic hematopoietic stem cell transplantation (HSCT), are major causes of morbidity and mortality after transplantation. Among LONIPCs, we occasionally treat patients with late-onset severe restrictive lung defect after HSCT; however, its clinical features have not been fully elucidated. METHODS: A retrospective chart review of a single center on cases of late-onset severe restrictive lung defect after HSCT was performed...

BACKGROUND: Pirfenidone is currently approved in the EU for the treatment of mild to moderate idiopathic pulmonary fibrosis (IPF) and offers a beneficial risk-benefit profile. However, there are several other, progressive fibrotic lung diseases, in which conventional anti-inflammatory therapy is not sufficiently effective and antifibrotic therapies may offer a novel treatment option. METHODS/DESIGN: We designed a study protocol for inclusion of patients with progressive fibrotic lung disease despite conventional anti-inflammatory therapy (EudraCT 2014-000861-32)...

Pleuroparenchymal fibroelastosis (PPFE) is now a defined clinicopathologic entity in the updated 2013 ATS/ERS classification of idiopathic interstitial pneumonias (IIPs), which has led to a significant increase in cases being diagnosed at our institution. We have therefore reviewed 43 PPFE cases (58 biopsies in total) to assess whether any clinical or histopathologic features provide prognostic information. A semiquantatitive grading system was used to assess extent of fibroblastic foci, intra-alveolar fibroelastosis, visceral pleural fibrosis, chronic inflammation in areas of fibrosis, vascular fibrointimal thickening, and presence of granulomas...

Introdcution: The prognosis of patients with an acute exacerbation of interstitial pneumonia (AE-IP) is poor. Pirfenidone (PFD) reduces the disease progression in idiopathic pulmonary fibrosis. OBJECTIVES: The purpose of this study was evaluating whether the administration of PFD improved the outcomes of AE-IP. METHODS: We conducted a retrospective study of 31 patients with AE-IP who did not recover between 7 and 14 days after an initial treatment. Fourteen patients received PFD within 2 weeks (PFD group) of the AE, while 17 patients were treated without PFD (Non-PFD group)...
