Integrated approach to bronchoalveolar lavage cytology to distinguish interstitial lung diseases.

Eur J Intern Med 2021 Apr 27. Epub 2021 Apr 27.

Department of Medical Sciences, Surgery and Neurosciences, Respiratory Disease and Lung Transplant Unit, Siena University, Siena, Italy.

Background: Broncho-alveolar lavage (BAL) is a safe diagnostic procedure, useful for differentiating fibrotic lung disorders and for excluding malignancy and infection. A recent multicenter study demonstrated a new, relatively sensitive, and specific index called Bronchoalveolar Cytology Threshold (BCT), useful for distinguishing healthy individuals from patients with lung diseases.

Objectives: In our study, BCT was applied for the first time to the analysis of interstitial lung diseases (ILDs), investigating its potential for differential diagnosis. Read More

Interstitial lung abnormality (ILA) and nonspecific interstitial pneumonia (NSIP).

Eur J Radiol Open 2021 16;8:100336. Epub 2021 Mar 16.

Center for Pulmonary Functional Imaging, Department of Radiology, Brigham and Women's Hospital and Harvard Medical School, Boston, MA, USA.

This review article aims to address mysteries existing between Interstitial Lung Abnormality (ILA) and Nonspecific Interstitial Pneumonia (NSIP). The concept and definition of ILA are based upon CT scans from multiple large-scale cohort studies, whereas the concept and definition of NSIP originally derived from pathology with evolution to multi-disciplinary diagnosis. NSIP is the diagnosis as Interstitial Lung Disease (ILD) with clinical significance, whereas only a part of subjects with ILA have clinically significant ILD. Read More

Interstitial Lung Disease in Common Variable Immunodeficiency.

Front Immunol 2021 11;12:605945. Epub 2021 Mar 11.

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

Interstitial lung disease (ILD) is a common complication in patients with common variable immunodeficiency (CVID) and often associated with other features, such as bronchiectasis and autoimmunity. As the ILD term encompasses different acute and chronic pulmonary conditions, the diagnosis is commonly made based on imaging features; histopathology is less frequently available. From a cohort of 637 patients with CVID followed at our center over 4 decades, we reviewed the data for 46 subjects (30 females, 16 males) who had lung biopsies with proven ILD. Read More

Organizing pneumonia and COVID-19: A report of two cases.

Respir Med Case Rep 2021 31;32:101359. Epub 2021 Jan 31.

Department of Internal Medicine II at Santa Maria Hospital, Centro Hospitalar Universitário Lisboa Norte, EPE, Portugal.

Organizing pneumonia (OP) is a sub-acute process of pulmonary tissue repair secondary to lung injury, defined histopathologically by intra-alveolar buds of granulation tissue within the lumen of distal pulmonary airspaces. It can be either cryptogenic or secondary (SOP) to different clinical conditions, namely infections. Despite being nonspecific, its diagnosis can be made by the association of clinical and imaging criteria. Read More

Am J Med Sci 2021 04 22;361(4):526-533. Epub 2020 Nov 22.

Department of Pulmonary and Critical Care Medicine, Albany Medical Center, New York.

Antisynthetase syndrome (AS) is a rare disease that affects patients with inflammatory myopathies such as polymyositis (PM) and dermatomyositis (DM). In patients with AS, up to 95% of patients develop antisynthetase syndrome-associated interstitial lung disease (AS-ILD). Although AS-ILD commonly occurs in patients with a well-established diagnosis of AS, it can be the first or only manifestation of an occult AS. Read More

COVID-19 mimics on chest CT: a pictorial review and radiologic guide.

Br J Radiol 2021 Feb 9;94(1118):20200703. Epub 2020 Dec 9.

Department of Radiology, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil.

Chest imaging is often used as a complementary tool in the evaluation of coronavirus disease 2019 (COVID-19) patients, helping physicians to augment their clinical suspicion. Despite not being diagnostic for COVID-19, chest CT may help clinicians to isolate high suspicion patients with suggestive imaging findings. However, COVID-19 findings on CT are also common to other pulmonary infections and non-infectious diseases, and radiologists and point-of-care physicians should be aware of possible mimickers.

Radiographic features and poor prognostic factors of interstitial lung disease with nivolumab for non-small cell lung cancer.

Cancer Sci 2021 Apr 24;112(4):1495-1505. Epub 2021 Feb 24.

The Jikei University School of Medicine, Tokyo, Japan.

Nivolumab can cause interstitial lung disease (ILD), which may be fatal; however, mortality risk factors have not been identified. This postmarketing study evaluated the poor prognostic factors of ILD in nivolumab-treated patients with non-small cell lung cancer (NSCLC) in Japan. Clinical and chest imaging findings for each ILD case were assessed by an expert central review committee, and prognosis was evaluated by radiographic findings, including the presence/absence of peritumoral ground-glass opacity (peritumoral-GGO).

Are there overlapping clinical features between thoracic radiotherapy side effects and covid-19 pneumonia? Radiation pneumonitis outside the radiation ports: Three case reports.

Clin Transl Radiat Oncol 2020 Nov 25;25:107-111. Epub 2020 Sep 25.

Radiation Oncology Unit, San Giuseppe Moscati Hospital, Strada per Martina Franca 74100, Taranto, Italy.

Respiratory involvement of COVID-19 infection, with presentations ranging from a mild flu-like illness to potentially lethal acute respiratory distress syndrome, is the main clinical manifestation in adults. Chest imaging shows a pictorial fashion of images due to the severity and stage of the disease, starting from focal nodular or mass-like opacities with air bronchogram to areas of ground glass consolidation or whited out lung. However, during the COVID-19 pandemic, CT findings could yield confounding reporting in the case of cancer patients previously treated with thoracic radiotherapy (tRT) due to atypical radiation pneumonitis occurring outside the radiation ports.

SARS-CoV-2 organising pneumonia: 'Has there been a widespread failure to identify and treat this prevalent condition in COVID-19?'

BMJ Open Respir Res 2020 09;7(1)

School of Medicine and Public Health, University of Wisconsin-Madison, Madison, Wisconsin, USA.

Reviews of COVID-19 CT imaging along with postmortem lung biopsies and autopsies indicate that the majority of patients with COVID-19 pulmonary involvement have secondary organising pneumonia (OP) or its histological variant, acute fibrinous and organising pneumonia, both well-known complications of viral infections. Further, many publications on COVID-19 have debated the puzzling clinical characteristics of 'silent hypoxemia', 'happy hypoxemics' and 'atypical ARDS', all features consistent with OP. The recent announcement that RECOVERY, a randomised controlled trial comparing dexamethasone to placebo in COVID-19, was terminated early due to excess deaths in the control group further suggests patients present with OP given that corticosteroid therapy is the first-line treatment.

Clinical and radiological features of immune checkpoint inhibitor-related pneumonitis in lung cancer and non-lung cancers.

Br J Radiol 2020 Nov 12;93(1115):20200409. Epub 2020 Aug 12.

Department of Radiology, Tenri Hospital, Nara, Japan.

Objective: To investigate the clinical and radiological features of immune checkpoint inhibitor-related pneumonitis (ICI-P), a rare but serious pulmonary complication of cancer immunotherapy and to evaluate key differences between lung cancer (LC) and non-LC patients.

Department of Radiodiagnosis, Dr B.R.A. Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi, India.

Chemotherapy while revolutionizing cancer management by improving survival and quality of life; is also associated with several adverse effects. Lung is the most common organ affected in chemotherapy-related complications, due to either drug toxicity or more commonly due to infections caused by immunosuppression and less commonly due to immune-mediated injury. Radiology, when used in combination with clinical and lab data, can help reach the specific diagnosis or narrow down the differentials. Read More
