Immunotherapy is becoming a standard of care for many cancers. Immune-checkpoint inhibitors (ICI) can generate immune-related adverse events. Interstitial lung disease (ILD) has been identified as a rare but potentially severe event.Between December 2015 and April 2016, we conducted a retrospective study in centres experienced in ICI use. We report the main features of ICI-ILD with a focus on clinical presentation, radiological patterns and therapeutic strategies.We identified 64 (3.5%) out of 1826 cancer patients with ICI-ILD...

A 57-year-old woman with SAPHO (synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome presented with recurrent episodes of pneumonia. She was treated with multiple courses of antibiotics with no success. The transbronchial biopsy undertaken via bronchoscopy revealed organising pneumonia (OP). She was treated with steroids and responded well with full clinical recovery and normalisation of her chest X-ray.To our knowledge, this is the first reported case of OP in association with SAPHO syndrome. This case report highlights the importance of considering OP in patients with SAPHO syndrome who present with chest infection...

OBJECTIVES: Surveillance is a key component of any control strategy for health-care associated infections (HAIs) and antimicrobial resistance (AMR), and public availability of methodological aspects is crucial for the interpretation of the data. We sought to systematically review publicly available information for HAIs and/or AMR surveillance systems organised by public institutions or scientific societies in European countries. METHODS: A systematic review of scientific and grey literature following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was performed...

The finding of collections of macrophages/histiocytes in lung biopsy and bronchoalveolar lavage is relatively common in routine practice. This morphological feature in itself is pathological, but the exact clinical significance and underlying disease should be evaluated together with clinical data, functional respiratory and laboratory tests and imaging studies.Morphological characteristics of macrophages and their distribution along the different pulmonary structures should be examined carefully by pathologists...

Persistent pneumonias are frequent both in hospital and primary care settings. Several parameters have to be taken into account. Firstly the appropriateness of treatment; secondly the immune status of the host; and finally infectious complications need to be ruled out. Several non-infectious diagnoses can mimic a persistent infiltrate, such as neoplastic disorders, organising pneumonias, interstitial disorders and drug - or radiation-induced lung diseases. Uncommon pathogens will not respond to common treatment, for instance atypical bacteria, mycobacteria, fungi including Pneumocystis as well as viruses...

Cryptogenic Organising Pneumonia (COP) is a relatively rare condition and can be difficult to differentiate from Community acquired pneumonia (CAP). We report two cases which demonstrate the importance of considering this differential diagnosis in patients with spontaneous pneumothorax who have raised inflammatory markers or lung infiltrates. Our report highlights the value of serum procalcitonin as a biomarker in differentiating between community acquired pneumonia and cryptogenic organising pneumonia especially in the context of a high serum C-reactive protein...

INTRODUCTION: One of the strategies for the rational use of antibiotics is the use of the score for community-acquired pneumonia (CAP Score). This instrument clinically evaluates patients with community-acquired pneumonia, thereby facilitating decision making regarding the early and safe withdrawal of antibiotics. OBJECTIVE: To generate a translation and cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire in Spanish. MATERIALS AND METHODS: Authorization for cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire was obtained; the recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) and the European Organisation for Research and Treatment of Cancer (EORTC) were carried out through the following stages: forward translation, reconciliation, backward translation, harmonization, obtaining a provisional questionnaire, and applying the questionnaire in a pilot test...

BACKGROUND: Risk assessment and early warning (RAEW) are essential components of any infectious disease surveillance system. In light of the International Health Regulations (IHR)(2005), this study compares the organisation of RAEW in China and the Netherlands. The respective approaches towards surveillance of arboviral disease and unexplained pneumonia were analysed to gain a better understanding of the RAEW mode of operation. This study may be used to explore options for further strengthening of global collaboration and timely detection and surveillance of infectious disease outbreaks...

Hearing loss remains the most common long-term complication of pneumococcal meningitis (PM) reported in up to 30% of survivors. Streptococcus pneumoniae have been shown to possess different ototoxic properties. Here we present a novel ex vivo experimental setup to examine in detail the pattern of hair cell loss upon exposure to different S. pneumoniae strains, therefore recapitulating pathogen derived aspects of PM-induced hearing loss. Our results show a higher susceptibility towards S. pneumoniae-induced cochlear damage for outer hair cells (OHC) compared to inner hair cells (IHC), which is consistent with in vivo data...

INTRODUCTION: Accurate etiological diagnosis of meningitis is important, but difficult in resource-limited settings due to prior administration of antibiotics and lack of viral diagnostics. We aimed to develop and validate 2 real-time multiplex PCR (RT-PCR) assays for the detection of common causes of community-acquired bacterial and viral meningitis in South African children. METHODS: We developed 2 multiplex RT- PCRs for detection of S. pneumoniae, N. meningitidis, H...

We present five cases of cytomegalovirus (CMV) pneumonitis occurring in patients after recent T cell deplete allogeneic stem cell transplantation (AlloHSCT). These cases were complicated by an organising pneumonia (during the recovery period) with a predominantly central peribronchial pattern. All patients presented with evidence of active CMV pneumonitis which was treated successfully with anti-viral therapy but was followed by persistent severe dyspnoea, cough and hypoxia. High resolution computed tomography (HRCT) imaging showed widespread central peribronchial consolidation with traction bronchiectasis...

Graft failure represents a leading cause of mortality after organ transplantation. Acute late-onset graft failure has not been widely reported. The authors describe the demographics, CT imaging-pathology findings, and treatment of patients presenting with the latter. A retrospective review was performed of lung transplant recipients at two large-volume centers. Acute late-onset graft failure was defined as sudden onset of bilateral infiltrates with an oxygenation index <200 without identifiable cause or concurrent extrapulmonary organ failure...

BACKGROUND: Vitamin A deficiency (VAD) is a major public health problem in low- and middle-income countries, affecting 190 million children under five years of age and leading to many adverse health consequences, including death. Based on prior evidence and a previous version of this review, the World Health Organization has continued to recommend vitamin A supplementation for children aged 6 to 59 months. There are new data available from recently published randomised trials since the previous publication of this review in 2010, and this update incorporates this information and reviews the evidence...

OBJECTIVES: Extracorporeal membrane oxygenation is a rescue therapy used to support severe cardiorespiratory failure. Data on outcomes from severe community-acquired pneumonia in adults receiving rescue extracorporeal membrane oxygenation are mainly confined to single-center experiences or specific pathogens. We examined data from the Extracorporeal Life Support Organisation registry to identify risk factors for poor outcomes in adult patients with community-acquired pneumonia. DESIGN: Retrospective data analysis...

Loss of alveolar barrier function with subsequent respiratory failure is a hallmark of severe pneumonia. Although junctions between endo- and epithelial cells regulate paracellular fluid flux, little is known about their composition and regulation in the human alveolar compartment. High autofluorescence of human lung tissue in particular complicates the determination of subcellular protein localization. By comparing conventional channel mode confocal imaging with spectral imaging and linear unmixing, we demonstrate that background fluorescent spectra and fluorophore signals could be rigorously separated resulting in complete recovery of the specific signal at a high signal-to-noise ratio...

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...

The burden of serious fungal infection in Thailand is increasing but data regarding its incidence and prevalence are lacking. In this study we aimed to estimate the burden of serious fungal diseases in Thailand based on the size of the populations at risk and available epidemiological databases. Data derived from The Bureau of Epidemiology, Department of Disease Control, Thai Ministry of Public Health, World Health Organisation, international and local reports, and some unreported data were used. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology by LIFE...
