Prognostic Role of NLR, PLR and MHR in Patients With Idiopathic Pulmonary Fibrosis.

Front Immunol 2022 28;13:882217. Epub 2022 Apr 28.

Department of Respiratory and Critical Care Medicine, Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medicine School, Nanjing, China.

Background: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease with low survival time. Since the pathophysiological progression of IPF is closely associated with immunological and inflammatory responses, immune biomarkers, including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte-high density lipoprotein ratio (MHR), have the potential to predict overall survival in IPF patients.

Methods: A total of 278 patients with IPF were finally enrolled. Read More

Clinical and genetic findings in two siblings with X-Linked agammaglobulinemia and bronchiolitis obliterans: a case report.

BMC Pediatr 2022 04 5;22(1):181. Epub 2022 Apr 5.

Bioinformatics Laboratory-LABINFO, National Laboratory of Scientific Computation LNCC/MCTIC, Av. Getulio Vargas, 333, Quitandinha CEP: 25651-075 Petrópolis, Rio de Janeiro, Brazil.

Background: X-linked agammaglobulinemia (XLA) is an Inborn Errors of Immunity (IEI) characterized by pan-hypogammaglobulinemia and low numbers of B lymphocytes due to mutations in BTK gene. Usually, XLA patients are not susceptible to respiratory tract infections by viruses and do not present interstitial lung disease (ILD) such as bronchiolitis obliterans (BO) as a consequence of acute or chronic bacterial infections of the respiratory tract. Although many pathogenic variants have already been described in XLA, the heterogeneous clinical presentations in affected patients suggest a more complex genetic landscape underlying this disorder.

Seeking Relevant Biomarkers in Common Variable Immunodeficiency.

Front Immunol 2022 11;13:857050. Epub 2022 Mar 11.

Department of Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, United States.

Common variable immunodeficiency (CVID) is the most common symptomatic form of primary immunodeficiency. More than 50% of patients in some series suffer from autoimmune or inflammatory complications (the "CVID+" phenotype), and these are not adequately addressed by current treatments. Despite major advancements in genetics, the pathogenesis of the CVID+ phenotype has remained unexplained for most patients, necessitating the need for relevant biomarkers in both the clinic and research settings.

Pulmonary lymphoproliferative disorders in children: a practical review.

Pediatr Radiol 2022 Mar 29. Epub 2022 Mar 29.

Department of Radiology, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave., Cincinnati, OH, 45229, USA.

Pulmonary lymphoproliferative disorders represent an uncommon spectrum of proliferation of lymphoid tissue in the lung parenchyma ranging from benign hyperplasia to malignancy. They tend to occur in certain clinical situations and have typical imaging features that together can be used by the radiologist to suggest these entities as part of the differential diagnosis. We review key clinical, histopathological and computed tomography features of pulmonary lymphoproliferative disorders in children including follicular bronchiolitis, lymphoid interstitial pneumonia, granulomatous-lymphocytic interstitial lung disease, lymphoma and post-transplant lymphoproliferative disorder to familiarize the pediatric radiologist with this group of disorders.

Regulatory T Cells in Autoimmune Vasculitis.

Front Immunol 2022 28;13:844300. Epub 2022 Feb 28.

Department of Medicine, Mayo College of Medicine and Science, Rochester, MN, United States.

Blood vessels are indispensable for host survival and are protected from inappropriate inflammation by immune privilege. This protection is lost in patients with autoimmune vasculitides, a heterogeneous group of diseases causing damage to arteries, arterioles, and capillaries. Vasculitis leads to vascular wall destruction and/or luminal occlusion, resulting in hemorrhage and tissue ischemia. Read More

Interstitial pneumonia and diffuse alveolar damage in domestic animals.

Vet Pathol 2022 Mar 6:3009858221082228. Epub 2022 Mar 6.

Virginia-Maryland College of Veterinary Medicine, Blacksburg, VA.

Classification of pneumonia in animals has been controversial, and the most problematic pattern is interstitial pneumonia. This is true from the gross and histologic perspectives, and also from a mechanistic point of view. Multiple infectious and noninfectious diseases are associated with interstitial pneumonia, all of them converging in the release of inflammatory mediators that generate local damage and attract inflammatory cells that inevitably trigger a second wave of damage.

PD-1/PD-L1 inhibitor ameliorates silica-induced pulmonary fibrosis by maintaining systemic immune homeostasis.

Biomed Pharmacother 2022 Apr 2;148:112768. Epub 2022 Mar 2.

Department of Occupational Health and Occupational Disease, College of Public Health, Zhengzhou University, Zhengzhou, Henan, PR China. Electronic address:

Pulmonary fibrosis induced by silica particles is defined as silicosis, which is an incurable disease. The pathogenesis of silicosis is not completely clear, but it's certain that immune system dysfunction is closely related to it. Immune checkpoint inhibitors (ICIs) are emerging immunotherapeutic agents that mainly target adaptive immune cells, and there is abundant evidence that ICIs are of great value in cancer treatment.

Fibroblasts From Idiopathic Pulmonary Fibrosis Induce Apoptosis and Reduce the Migration Capacity of T Lymphocytes.

Front Immunol 2022 10;13:820347. Epub 2022 Feb 10.

Instituto Nacional de Enfermedades Respiratorias, "Ismael Cosío Villegas", Mexico City, Mexico.

Idiopathic pulmonary fibrosis (IPF) is a progressive and irreversible lung disease of unknown etiology. Myofibroblasts are organized in peculiar subepithelial fibroblasts foci (FF), where they abnormally persist and exclude lymphocytes by unclear mechanisms. FF are the source of an excessive extracellular matrix, which results in progressive stiffening and destruction of the lung architecture. Read More

ITK independent development of Th17 responses during hypersensitivity pneumonitis driven lung inflammation.

Commun Biol 2022 02 24;5(1):162. Epub 2022 Feb 24.

Department of Microbiology & Immunology, Cornell Center for Immunology, Cornell Institute for Host Microbe-Interactions and Disease, Cornell University, Ithaca, NY, USA.

T helper 17 (Th17) cells develop in response to T cell receptor signals (TCR) in the presence of specific environments, and produce the inflammatory cytokine IL17A. These cells have been implicated in a number of inflammatory diseases and represent a potential target for ameliorating such diseases. The kinase ITK, a critical regulator of TCR signals, has been shown to be required for the development of Th17 cells. Read More

Ann Rheum Dis 2022 Jun 21;81(6):854-860. Epub 2022 Feb 21.

Medicine, University of California Los Angeles, Los Angeles, California, USA.

Objectives: To characterise the peripheral blood cell (PBC) gene expression changes ensuing from mycophenolate mofetil (MMF) or cyclophosphamide (CYC) treatment and to determine the predictive significance of baseline PBC transcript scores for response to immunosuppression in systemic sclerosis (SSc)-related interstitial lung disease (ILD).

Methods: PBC RNA samples from baseline and 12-month visits, corresponding to the active treatment period of both arms in Scleroderma Lung Study II, were investigated by global RNA sequencing. Joint models were created to examine the predictive significance of composite modular scores for the course of forced vital capacity (FVC) per cent predicted measurements from 3 to 12 months.

Integrating RNA-Seq With GWAS Reveals a Novel SNP in Immune-Related Gene Associated With Occupational Pulmonary Fibrosis Risk: A Multi-Stage Study.

Front Immunol 2021 17;12:796932. Epub 2022 Jan 17.

Department of Epidemiology, School of Public Health, Nantong University, Nantong, China.

Objective: To evaluate the association between single-nucleotide polymorphisms (SNPs) in RNA-seq identified mRNAs and silicosis susceptibility.

Methods: A comprehensive RNA-seq was performed to screen for differently expressed mRNAs in the peripheral blood lymphocytes of eight subjects exposed to silica dust (four silicosis cases and four healthy controls). Following this, the SNPs located on the shortlisted mRNAs, which may affect silicosis susceptibility, were screened through silicosis-related genome-wide association studies (GWAS) (155 silicosis cases and 141 healthy controls), whereas functional expression quantitative trait locus (eQTL)-SNPs were identified using the GTEx database.
