INTRODUCTION    Interleukin 27 (IL‑27) is a cytokine secreted mostly by antigen‑presenting cells. It is important for the immune polarization of T helper‑1 (Th1) cells, and its role in interstitial lung diseases (ILDs) and lung cancer has been investigated. OBJECTIVES    We assessed IL‑27 expression in the lower airways of patients with selected ILDs and early‑stage non-small cell lung cancer (NSCLC). PATIENTS AND METHODS    IL‑27 concentrations were examined by an enzyme‑linked immunosorbent assay in bronchoalveolar lavage (BAL) fluid supernatants collected from patients with pulmonary sarcoidosis (PS; n = 30), extrinsic allergic alveolitis (EAA; n = 14), idiopathic pulmonary fibrosis (IPF; n = 12), nonspecific interstitial pneumonia (NSIP; n = 14), and NSCLC stages I to IIa (n = 16) with peripheral localization, and in controls (n = 14)...

BACKGROUND: Diffuse interstitial pneumonias are considered as a group of multiple affections characterized by challenging diagnoses because of the lack of specific clinical signs. Radiologic investigations highlight the diagnoses in most of the cases but bronchoalveolar lavage plays a key role in the diagnostic diagram. We aim to compare the immunocytochemical technique and the flow cytometry in the phenotyping of lymphocytic alveolitis. METHODS: We described a series of 32 lymphocytic alveolitis, which were analyzed using immunocytochemistry and flow cytometry...

Hypersensitivity pneumonitis (HP) is categorized as a Type-1 helper (Th1) disease. The resulting granuloma formation is dependent on T cells and the Th1 cytokine interferon (IFN)-γ. In experimental setting, the production of IFN-γ-induced protein 10 (IP-10), monokine induced by IFN-γ (MIG), IFN-inducible T-cell-alpha chemoattractant (I-TAC), has been shown (in mice exposed to the particulate antigens that cause HP) during the development of HP. The production of these chemokines was associated with an influx of chemokine (C-X-C motif) receptor (CXCR)3 CXCR3(+)/CD4(+) T cells into lungs...

OBJECTIVE: Bronchoalveolar lavage (BAL) is a diagnostic tool often used during the management of interstitial lung diseases (ILD). However, its diagnostic value in discrimination between entities comprising the very heterogenous group of ILD, is still a controversial issue. The objective of our study is to assess the diagnostic value of BAL in the management of ILD, by comparing the cytological findings in BAL fluid among the different diseases of this group. METHODS: It was a retrospective, observational study of 151 patients between January 2012 and December 2015...

A 59-year-old woman receiving methotrexate and tacrolimus for rheumatoid arthritis (RA) was referred to our hospital following bilateral ground-glass opacity observed in her chest X-ray and elevated serum KL-6. After methotrexate and tacrolimus cessation, shortness of breath developed and ground-glass opacity observed in the chest computed tomography rapidly worsened. Bronchoalveolar lavage showed increased lymphocytes, and trans-bronchial lung biopsy confirmed lymphocytic alveolitis. In addition, the patient had serum antibodies against Trichosporon asahii, a fungal pathogen...

We report a case of thoracic sarcoidosis in a 72-year-old female, snuff taker, who presented with multinodular pulmonary lesions on chest x-ray. Clinical and biological findings were poor. Thoracic imaging showed soft tissue density nodules with irregular borders. The diagnosis of 'cannon ball' metastases was suspected. A thorough investigation strategy could not prove malignancy. A complete radiologic clearing was obtained spontaneously within three months. A rereading of pathology slides performed afterwards showed multinucleated giant cells on hemorrhagic background with a lymphocytic alveolitis...

We report a case of a 38-year-old woman who was diagnosed with stage IV lung adenocarcinoma, harboring an epidermal growth factor receptor (EGFR) L858R mutation on exon 21 and a T790 M mutation on exon 20. The patient was treated with osimertinib, a third-generation EGFR tyrosine kinase inhibitor (EGFR-TKI) following treatment with nivolumab, an anti-Programmed Cell Death 1 (anti-PD1) antibody. After initiating osimertinib treatment, the patient began to complain of low-grade fever and shortness of breath without hypoxemia, and her chest radiograph and a CT scan revealed a remarkable antitumor response, although faint infiltrations were observed in the bilateral lung field...

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. 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...

Sarcoidosis is a granulomatous disease characterized by a T-helper type 1 (Th1) cell-dominated alveolitis. As a role of bacteria in the pathogenesis of sarcoidosis has been discussed, Toll-like receptors (TLRs) may be involved in the initiation of a first immune reaction. We analyzed expression and functional relevance of several TLRs in bronchoalveolar lavage (BAL) cells from patients with pulmonary sarcoidosis. In parallel, we determined the release of C-X-C motif chemokine 9 (CXCL9), CXCL10, and CXCL11 by BAL cells from patients with pulmonary sarcoidosis...

BACKGROUND: The CD103 integrin is present on CD4+ lymphocytes of the bronchial mucosa, but not on peripheral blood CD4+ lymphocytes. It has been hypothesized that CD4+ lymphocytes in pulmonary sarcoidosis originate from redistribution from the peripheral blood to the lung, and therefore do not bear the CD103 integrin. Some data suggest that a low CD103+ percentage among bronchoalveolar lavage fluid (BALF) CD4+ lymphocytes discriminates between sarcoidosis and other diagnoses. OBJECTIVE: To determine the diagnostic value of BALF CD103+ to identify sarcoidosis among other causes of alveolar lymphocytosis in a large retrospective case series...

Although bronchoalveolar lavage (BAL) is often used in the diagnosis of interstitial lung diseases (ILDs), its importance in investigating, in particular, idiopathic pulmonary fibrosis (IPF) is controversial. The cell distributions in the BAL are taken into account in the clinical routine, non-cellular characteristics of the BAL play no role.Using mathematical modeling of data, the present work investigated the extent to which BAL features enable drawing conclusions about the underlying ILK or help exclude IPF...

BACKGROUND: Renal complications in Graves' disease are rare and may be related either to the disease itself or secondary to antithyroid drugs. AIM: We report 6 cases of renal damage in patients with Graves' disease treated with Benzylthiouracil collected over a period of 14 years. METHODS: There were 6 women with a mean age of 37.86 ± 14.25 years. All patients developed renal vasculitis associated with ANCA. The signs were dominated by renal proteinuria and renal failure associated with hematuria in all cases...

Immunosuppression associated with human immunodeficiency virus (HIV) infection impacts all components of host defense against pulmonary infection. Cells within the lung have altered immune function and are important reservoirs for HIV infection. The host immune response to infected lung cells further compromises responses to a secondary pathogenic insult. In the upper respiratory tract, mucociliary function is impaired and there are decreased levels of salivary immunoglobulin A. Host defenses in the lower respiratory tract are controlled by alveolar macrophages, lymphocytes, and polymorphonuclear leukocytes...

Hypersensitivity pneumonitis (HP) is an immune-mediated interstitial lung disease that develops following repeated exposure to inhaled environmental antigens. The disease results in alveolitis and granuloma formation and may progress to a chronic form associated with fibrosis; a greater understanding of the immunopathogenic mechanisms leading to chronic HP is needed. We used the Saccharopolyspora rectivirgula (SR) mouse model of HP to determine the extent to which a switch to a Th2-type immune response is associated with chronic HP...

BACKGROUND: Antigen presenting cells play a pivotal role in the adaptive immune response in hypersensitivity pneumonitis (HP). It was hypothesised that lymphangiogenesis is involved in the pathophysiology of HP via cell transport. OBJECTIVE: To determine the clinical significance of lymphangiogenic factors in HP. METHODS: Levels of vascular endothelial growth factors (VEGF)-A, VEGF-C, VEGF-D and CCL21 in the serum and bronchoalveolar lavage fluid (BALF) were measured in 29 healthy volunteers, 14 patients with idiopathic pulmonary fibrosis (IPF) and 26 patients with HP by ELISA...

BACKGROUND: Crizotinib, an oral tyrosine kinase inhibitor that targets anaplastic lymphoma kinase, has proven to offer sustained progression-free survival in anaplastic lymphoma kinase-rearranged non-small-cell lung cancers. Occurrence of severe interstitial lung disease (ILD) was one of the crucial adverse events reported in randomized clinical trials and case reports. METHODS: In September 2011, we observed a crizotinib-associated ILD case. Following this index case, we reviewed the clinical and computed tomographic scan features of all patients treated with crizotinib in our department, between October 2010 and July 2013, comparing patients with and without ILD...

Although radiation pneumonitis is usually confined to irradiated areas, some studies have reported that radiation-induced lymphocytic alveolitis can also spread to the non-irradiated lung. However, there have been few reports of radiation-induced eosinophilic alveolitis. We report the case of a 27-year-old female with radiation pneumonitis, occurring 4 months after radiation therapy for cancer of the left breast. Clinical and radiological relapse followed withdrawal of corticosteroids. Examination of bronchoalveolar lavage (BAL) in patchy airspace consolidations revealed increased eosinophil counts...

Histamine H1 antagonists rarely cause drug-induced lung injury (DLI). A woman in her 60s, who had been taking antihistaminic levocetirizine for 2 months, presented with progressive cough and shortness of breath. A chest radiograph showed patchy infiltrations on both lower lung fields. Chest computed tomography findings were consistent with non-specific interstitial pneumonia. Serum markers associated with interstitial pneumonias were elevated. Room air arterial blood gas analysis revealed hypoxemia. Restrictive ventilatory impairment was noted with reduced diffusing capacity...

INTRODUCTION: Farmer's lung (FL) is the most common type of hypersensitivity pneumonitis (HP), with an estimated prevalence of between 0.5 and 1.5% in dairy farmers. In chronic FL, fibrotic sequelae are widely described in the literature although our experience and occasional epidemiological studies emphasize an increased risk of developing emphysema in these patients. CASE REPORT: We report a case of FL in a 37-year-old patient with typical clinical features (exertional dyspnoea, lymphocytic alveolitis and computed tomography appearances) together with proven allergen exposure...
