Glucocorticoids versus glucocorticoids plus cyclophosphamide in eosinophilic granulomatosis with polyangiitis with poor-prognosis factors.

Objectives: Current guidelines suggest treating poor-prognosis eosinophilic granulomatosis with polyangiitis (EGPA) with a combination of glucocorticoids (GCs) plus cyclophosphamide (CYC). However, there is little data to support the need for the addition of CYC. The objective of this study was to compare GCs plus CYC to GCs alone as induction therapy in poor-prognosis EGPA.

Correlation of high-resolution computed tomography and immunological bronchoalveolar lavage in interstitial lung disease at the onset of inflammatory rheumatic diseases: implications for diagnosis and therapeutic strategies.

Objectives: Inflammatory rheumatic diseases (IRD) are often associated with interstitial lung disease (ILD). The aim of the present study was to establish a correlation between the findings on HRCT and the immunological bronchoalveolar lavage (BAL).

Methods: The study included 74 patients with newly diagnosed IRD and evidence of ILD on HRCT with the following pattern: ground-glass opacities (GGO), non-specific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP).

[Is JAK inhibition an option in the treatment of interstitial lung disease in rheumatoid arthritis?].

A 69-year-old male patient with seropositive erosive rheumatoid arthritis (RA) presented to our clinic due to progressive dyspnea. High-resolution computed tomography (HRCT) and immunological bronchioalveolar lavage revealed ground-glass opacities and a lymphocytic alveolitis caused by interstitial lung disease (ILD) in RA. Considering previous forms of treatment, disease-modifying antirheumatic drug (DMARD) treatment was switched to tofacitinib.

Diagnosing lung involvement in inflammatory rheumatic diseases-Where do we currently stand?

Lung involvement is the most common and serious organ manifestation in patients with inflammatory rheumatic disease (IRD). The type of pulmonary involvement can differ, but the most frequent is interstitial lung disease (ILD). The clinical manifestations of IRD-ILD and severity can vary from subclinical abnormality to dyspnea, respiratory failure, and death.

Assessing the diagnostic value of a potential screening tool for detecting early interstitial lung disease at the onset of inflammatory rheumatic diseases.

Background: Interstitial lung disease (ILD) is a severe pulmonary complication in inflammatory rheumatic diseases (IRD) and associated with significantly increased morbidity and mortality. That is why ILD screening at a very early stage, at the onset of IRD, is essential. The objective of the present study was to evaluate the diagnostic value and utility of a stepwise approach as a potential ILD screening tool in patients with newly diagnosed IRD.

Organ Manifestation and Systematic Organ Screening at the Onset of Inflammatory Rheumatic Diseases.

Background: Inflammatory rheumatic diseases (IRD) are often associated with the involvement of various organs. However, data regarding organ manifestation and organ spread are rare. To close this knowledge gap, this cross-sectional study was initiated to evaluate the extent of solid organ manifestations in newly diagnosed IRD patients, and to present a structured systematic organ screening algorithm.

Significance of PR3-ANCA positivity in eosinophilic granulomatosis with polyangiitis (Churg-Strauss).

Objectives: Only a third of patients with eosinophilic granulomatosis with polyangiitis (EGPA) are ANCA-positive, mainly directed against MPO. ANCA directed against PR3 are rarely found in EGPA. We aimed to examine the significance of PR3-ANCA in EGPA.

Still Fighting for Breath: a patient survey of the challenges and impact of severe asthma.

We conducted a large global survey, Still Fighting for Breath, in patients with severe persistent asthma, 10 years after the Fighting for Breath survey to assess the impact of disease on patients' lives and to determine if control and management have changed in recent years. Data were collected from 1333 adults (aged >18 years) and caregivers of children (aged 6-17 years) with severe persistent asthma from nine countries through an online survey conducted in 2016 by GfK. A decade after the first survey, our results showed that the impact of severe asthma has not changed significantly and a high proportion of patients with severe asthma remain inadequately controlled.

[Vasculitides and eosinophilic pulmonary diseases].

Eosinophilic granulocytes form peripheral effector cells controlled by Th2 lymphocytes, which cause local cell, tissue, and functional disorders of infiltrated organs via the release of cytotoxic basic proteins and oxygen radicals. Diseases associated with eosinophilia include systemic and organ-related forms. The lungs are involved in eosinophilic granulomatosis with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome), acute and chronic eosinophilic pneumonia, as well as in an organ manifestation in hypereosinophilic syndrome and certain parasitic diseases.

Interferon-α for Induction and Maintenance of Remission in Eosinophilic Granulomatosis with Polyangiitis: A Single-center Retrospective Observational Cohort Study.

Objective: Eosinophilic granulomatosis with polyangiitis (EGPA) is characterized by frequent relapses following induction therapy. Interferon-α (IFN-α) can reverse the underlying Th2-driven immune response and has successfully induced remission in previous reports. We undertook this study to investigate its efficacy and safety in patients with EGPA.

Anthracofibrosis Manifesting as False-Positive Iodine Accumulation in a Patient With Recent History of Thyroid Carcinoma.

A 33-year-old Indonesian woman presented for follow-up after a recent history of papillary thyroid carcinoma treated with total thyroidectomy and radioiodine therapy. A 131I whole-body scintigraphy showed an elongated iodine accumulation in the right hemithorax. On suspicion of pulmonary metastasis, further diagnostics with 124I PET/CT showed thickening of the bronchial wall and retention of secretion in a middle lobe bronchus.

Lung disease and ulcerative colitis--mesalazine-induced bronchiolitis obliterans with organizing pneumonia or pulmonary manifestation of inflammatory bowel disease?

Ulcerative colitis can be associated with numerous extraintestinal organ manifestations. Pulmonary disease in inflammatory bowel disease (IBD) is supposed to be a rare entity and has to be distinguished from infectious complications and side-effects of medications used in the treatment of IBD. We present the case of a 20-year-old male patient with ulcerative colitis and a 4-week history of respiratory symptoms, malaise, fever and respiratory insufficiency under a medication with mesalazine.

[German guideline for diagnosis and management of idiopathic pulmonary fibrosis].

Idiopathic pulmonary fibrosis is a fatal lung disease with a variable and unpredictable natural history and limited treatment options. Since publication of the ATS-ERS statement on IPF in the year 2000 diagnostic standards have improved and a considerable number of randomized controlled treatment trials have been published necessitating a revision. In the years 2006 - 2010 an international panel of IPF experts produced an evidence-based guideline on diagnosis and treatment of IPF, which was published in 2011.

Interferon-α induced remission in three patients with eosinophilic granulomatosis and polyangiitis. A case study.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic small vessel vasculitis associated with asthma and eosinophilia. Optimal therapy for maintenance of remission is yet to be defined. We present a case-series of three patients with EGPA in whom IFN-α, an immunomodulatory cytokine induced remission, which was maintained even after discontinuation of the drug.

Lung ultrasound in the diagnosis and follow-up of community-acquired pneumonia: a prospective, multicenter, diagnostic accuracy study.

Background: The aim of this prospective, multicenter study was to define the accuracy of lung ultrasound (LUS) in the diagnosis of community-acquired pneumonia (CAP).

Methods: Three hundred sixty-two patients with suspected CAP were enrolled in 14 European centers. At baseline, history, clinical examination, laboratory testing, and LUS were performed as well as the reference test, which was a radiograph in two planes or a low-dose CT scan in case of inconclusive or negative radiographic but positive LUS findings.

[Therapy for small airways disease: basic principles and therapeutic implications].

This paper describes the possibility of targeting the small airways. In addition to aiding in the therapy for chronic obstructive lung diseases this may prove to be invaluable in the development of treatment strategies for diseases of the bronchioli. Essential factors in peripheral lung deposition include extra-fine particles, a slow and controlled inspiratory flow and an endexspiratory breathhold of 5 - 10 sec (especially for steroids).

[Lung function diagnostics for the small airways].

In the recent years growing interest has focused on the involvement of the distal airways (internal diameter < 2 mm) in obstructive lung diseases and other pulmonary conditions. Inflammation in the small airways seems to play a major role in severe and uncontrolled asthma as a major determinant of airflow obstruction. Thus, small airways represent an important target for inhalation therapy.

[Bronchiolitis].

Due to the variability in respect to aetiology, histopathology, lung function, imaging and clinical presentation, as well as overlapping parenchymal processes, bronchiolar disorders are generally difficult to diagnose. Thus, diseases of the small airways should generally be considered in the differential diagnostic approach to respiratory conditions. The diagnostic approach can be devided into several steps: in steps 1 (history and physical examination) and 2 (plain chest radiographs and pulmonary function tests) may point towards a bronchiolar pulmonary process.

[Bronchiolitis. Part 1--anatomic features, classification, clinical presentation and imaging].

The term "bronchiolitis" refers to a broad spectrum of common conditions related to the small airways associated with a miscellaneous aetiology, histology, clinical features and course. Due to their variability, bronchiolar disorders are generally difficult to diagnose. History (smoking, collagen vascular disease, inhalational injury, medication usage, and organ transplant) may point towards a bronchiolar process.

Omalizumab in patients with severe asthma: the XCLUSIVE study.

Background And Aims: Although the efficacy and safety of omalizumab (OMA) in uncontrolled severe allergic asthma has been demonstrated in several randomised controlled trials (RCTs), information on the treatment in a practice-related setting is limited. Thus, the purpose of this prospective multi-centre study (XCLUSIVE) was to investigate the efficacy, compliance and utilisation of OMA therapy in real-life clinical practice in Germany.

Methods: One hundred ninety-five asthmatic patients initiated on anti-Immunoglobulin E (IgE) IgE treatment were followed-up for 6 months.

[Airway complications following lung transplantation - clinic, diagnosis, and interventional management].

Tracheobronchial complications following lung transplantation are defined as local structural or infectious alterations of the airways, which occur early or several months after lung transplantation (LTx). They preferentially develop in the region of the bronchial anastomosis. The most frequently reported complications are bronchial stenosis, bronchial dehiscence, exophytic excessive granulation tissue formation, tracheo-bronchomalacia, bronchial fistulas, and endobronchial infections.
