REVIEW
Martina Bonifazi, M Angeles Montero, Elisabetta A Renzoni
PURPOSE OF THE REVIEW: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare fibrosing lung disease, affecting the visceral pleura and the subpleural parenchyma with an upper lobe predilection, included as a distinct clinicopathologic entity in the latest international multidisciplinary classification of the idiopathic interstitial pneumonias (IIP). We aim to summarize the current evidence on IPPFE, in terms of clinical features and potential treatments. RECENT FINDINGS: Overall, there is increasing awareness of PPFE in association with a separate ILD pattern...

It is difficult to differentiate Pneumocystis pneumonia (PCP) from rituximab-induced interstitial lung disease (RILD) in lymphoma patients with diffuse pulmonary infiltrates who are receiving rituximab-containing chemotherapy. Using a clinical scoring system, we aim to differentiate PCP from RILD who are receiving rituximab-containing chemotherapy. We reviewed the medical records of lymphoma patients who had received rituximab-containing chemotherapy between 2012 and 2015 in a tertiary hospital. Among 613 lymphoma patients receiving rituximab-containing chemotherapy, 97 (16%) had diffuse pulmonary infiltrates...

Primary Sjögren syndrome (pSS)-related interstitial lung disease (ILD) involved about 10-20% of patients. In 20% of cases, ILD can be diagnosed before pSS; anyway, few studies have investigated the frequency of ILD as the first clinically relevant manifestation of pSS, generally referred to retrospective studies. Aim of our prospective study was to describe prevalence, clinical, serological, and instrumental features of non-sicca onset pSS patients with interstitial lung involvement. During a period of 48 months, all consecutive patients diagnosed as pSS were enrolled...

BACKGROUND: Nivolumab is a human monoclonal IgG4 antibody that inhibits programmed cell death protein 1 (PD-1) expressed on activated T cells. We investigated the safety and activity of nivolumab in patients with treatment-refractory oesophageal cancer. METHODS: We did an open-label, single-arm, multicentre phase 2 study. Eligible patients had advanced squamous-cell carcinoma, adenosquamous-cell carcinoma, or adenocarcinoma of the oesophagus refractory or intolerant to fluoropyrimidine-based, platinum-based, and taxane-based chemotherapy...

A 65-year-old man was referred to our hospital for the treatment of a lesion on the medial lacrimal canthus of both eyes. He had a history of perinuclear anti-neutrophil cytoplasmic antibodies, i.e., pANCA-positive interstitial pneumonia. Orbital magnetic resonance imaging excluded space occupying lesions, and laboratory testing excluded thyroid-related diseases. The masses were excised, and histopathological examinations showed sebaceous gland hyperplasia and inflammatory changes around the gland. In addition, the specimen from the left eye showed a retention cyst possibly caused by an infection...

BACKGROUND: Current understanding of human immunodeficiency virus (HIV)-associated pulmonary cryptococcosis (PC) is largely based on studies performed about 2 decades ago which reported that the most common findings on chest radiograph were diffuse interstitial infiltrates. Few studies are available regarding the computed tomography (CT) findings. The aim of this study was to characterize chest CT features of HIV-associated PC. METHODS: HIV patients with cryptococccal infection and pulmonary abnormalities on Chest CT between September 2010 and May 2016 in the Second Affiliated Hospital of the Southeast University were retrospectively analyzed...

Pulmonary fibrosis is common in a variety of inflammatory lung diseases, such as interstitial pneumonia, chronic obstructive pulmonary disease, and silicosis. There is currently no effective clinical drug treatment. It has been reported that grape seed extracts (GSE) has extensive pharmacological effects with minimal toxicity. Although it has been found that GSE can improve the lung collagen deposition and fibrosis pathology induced by bleomycin in rat, its effects on pulmonary function, inflammation, growth factors, matrix metalloproteinases and epithelial-mesenchymal transition remain to be researched...

Usual interstitial pneumonia (UIP) is characterized by progressive scarring of the lungs and is associated with high morbidity and mortality despite therapeutic interventions. Sex steroid receptors have been demonstrated to play an important role in chronic lung conditions; however, their significance is unknown in patients with UIP. We retrospectively reviewed 40 idiopathic UIP cases for the expression of hormonal receptors. Forty cases including 10 normal lung, 10 cryptogenic organizing pneumonia (COP), 10 idiopathic organizing diffuse alveolar damage (DAD), 7 hypersensitivity pneumonitis (HP) and 3 nonspecific interstitial pneumonitis (NSIP) served as controls...

BACKGROUND: Some patients with autoimmune characteristics and idiopathic interstitial pneumonia (IIP), particularly usual interstitial pneumonia (UIP), do not fit neatly into the category of connective tissue disease associated interstitial lung disease (CTD-ILD), idiopathic pulmonary fibrosis (IPF) or recently proposed yet to be validated criteria for interstitial pneumonia with autoimmune features (IPAF). Outcomes of these patients are unknown. METHODS: Retrospective single center study; ANOVA analyses compared differences in mean change in forced vital capacity (FVC) and diffusion capacity (DLCO) over 1-year among 124 well defined patients (20 AI-ILD [positive autoantibodies with or without symptoms of CTD], 15 IPAF, 36 CTD-ILD, 53 "Lone-IPF" [patients with IPF without any autoantibodies]) RESULTS: 75% of patients with AI-ILD, 33% IPAF, and 33% CTD-ILD had UIP...

BACKGROUND AND OBJECTIVE: Unclassifiable disease in chronic interstitial lung disease (ILD) is a common and challenging problem but has been insufficiently studied. The 2013 update of the international multidisciplinary classification of the idiopathic interstitial pneumonias presented a classification based on observed disease behaviour with the purpose of providing guidance to clinicians in the management of these patients. The aim of this study was to apply the new disease behaviour classification (DBC) and the previously validated ILD-gender age physiology (GAP) score to a cohort of unclassifiable ILD patients and to assess the prognostic value of these two composite approaches...

Vemurafenib improves survival of melanoma patients. However, cutaneous side-effects commonly occur in them. Nivolumab and ipilimumab are monoclonal antibodies against programmed death 1 and cytotoxic T-lymphocyte-associated antigen 4, both of which regulate excessive T-cell activation. Although these agents induce antitumor immunity against melanoma, the modified immune condition may result in an unexpected adverse reaction which has not been observed previously. Herein, we report a case who manifested severe erythema multiforme-like eruption with mucosal involvement associated with vemurafenib following nivolumab...

BACKGROUND: Pocket ultrasonography may enhance patient diagnosis and care. We sought to assess pocket ultrasound in detecting common conditions in the coronary care unit (CCU) compared to portable daily chest radiography (CXR) and conventional transthoracic echocardiography (TTE). METHODS: An experienced pocket ultrasound user performed a pocket ultrasound examination for interstitial edema, pneumonia, central line seen in the right ventricle, pleural and pericardial effusions, left atrial enlargement, and cardiomegaly...

Idiopathic pulmonary fibrosis is defined as chronic fibrosing interstitial pneumonia limited to the lung, with poor prognosis. The incidence has been rising in recent years probably due to improved diagnostic methods and increased life expectancy. In 2013, the SEPAR guidelines for the diagnosis and treatment for idiopathic pulmonary fibrosis were published. Since then, clinical trials and meta-analyses have shown strong scientific evidence for the use of pirfenidone and nintedanib in the treatment of idiopathic pulmonary fibrosis...

Infections with Pneumocystis jirovecii can result in asymptomatic colonization or induce life threatening clinical symptoms. However, there appears to be a 'gray area' between colonization and severe pneumonia that remains underestimated so far. We describe a case with chronic interstitial lung disease and chronic cough that was attributed to P. jirovecii. The patient's history of chronic cough, although very likely being fostered by the underlying Waldenström's macroglobulinemia and interstitial lung disease, was most likely caused by P...

BACKGROUND: Smith-Magenis syndrome (SMS) is a complex neurobehavioral disorder associated with recurrent otitis. Most SMS cases result from heterozygous interstitial chromosome 17p11.2 deletions that encompass not only the intellectual disability gene retinoic acid-induced 1 but also other genes associated with immunodeficiency, autoimmunity, and/or malignancy. OBJECTIVES: The goals of this study were to describe the immunological consequence of 17p11.2 deletions by determining the prevalence of immunological diseases in subjects with SMS and by assessing their immune systems via laboratory methods...

Viral metagenomic analysis detected a novel polyomavirus in a 6-month old female alpaca (Vicugna pacos) euthanized after a diagnosis of disseminated lymphosarcoma. The viral genome was fully sequenced, found to be similar to other polyomaviruses in gene architecture and provisionally named Alpaca polyomavirus or AlPyV. Viral nucleic acid was detected by PCR in venous blood, spleen, thymus, and lung. AlPyV phylogenetically clustered in the "Wuki" group of PyVs, which includes WU and KI polyomaviruses, commonly found in human respiratory samples...

Lymphocytic interstitial pneumonia (LIP) is on the spectrum of lymphoproliferative diseases that can affect the lungs. Although common in human immunodeficiency virus (HIV) infected children, it is rarely reported in adults. A 51-year-old HIV infected female patient presented with worsening dyspnea over five months. She had radiological findings of bilateral lung nodular infiltrates. Her CD4 count was 835 cells/uL and her HIV viral load was undetectable. Bronchoalveolar lavage did not yield any infectious pathogen...
