Abstract

Lung macrophages are essential for alveolar homeostasis and foreign body removal. Macrophage dysfunction can result in a pathological accumulation of surfactants, lipids and proteins in the alveoli called pulmonary alveolar proteinosis (PAP). Inhalation of indium-containing particles (ICPs) such as indium-tin oxide (ITO) is specifically associated with macrophage toxicity and PAP development. In vitro studies have demonstrated that ITO particles are phagocytosed and dissolved by macrophages which subsequently release ionic indium, the primary cytotoxic compound for these cells. Here, we performed in vivo and ex vivo studies to determine how ITP particles affect alveolar (AM) and interstitial (IM) macrophages, the two main macrophage populations of the lungs. After ITO instillation in mice, we observed a depletion of the AM subpopulation that coincided with PAP formation. In contrast, IM were persistently accumulated in treated mice, suggesting that AM is the main target of ITO toxicity. Paradoxically, IM phagocytosed more ITO particles and were more sensitive to ITO exposure than AM ex vivo. In contrast, ionic indium was highly cytotoxic for AM in comparison to IM. Our data obtained by using AM and IM co-cultures and endocytosis inhibitors suggested that IM phagocytose ITO particles and release ionic indium that forms complexes particularly cytotoxic for AM. These results suggested that both IM and AM contribute to ITO-induced PAP in mice. In addition, the specific depletion of AM in ITO-treated mice was related to a defect of IL-1α (not GM-CSF), an essential autocrine cytokine for AM replenishment during lung responses to particles. We concluded that alveolar clearance defect and PAP development after ICPs exposure result from the release of ionic indium and the abrogation of AM self-maintenance.

Abstract

Comprehensive illustrated guide to the much neglected area of parenchymal respiratory disease in children. It includes congenital disorders, disease in neonates, malignant disease, as well as neuromuscular and interstitial diseases. There is also a section on rarer disorders that are commonly misdiagnosed: scleroderma, granulatomas and other rheumatoid disorders, mucopolsaccharidoses, sickle-cell disease and rare neoplasms. This atlas provides paediatricians and respiratory specialists with an up to date visual guide that assists management of this group of diseases.

Abstract

Interstitial lung diseases comprise a significant part of any respiratory medicine practice.  This timely second edition of Diffuse Lung Disease is a practical clinically-oriented resource, covering all the major advances in diagnostic techniques and therapies.  Authored by world authorities in the field, this book provides clear and specific recommendations for the management of all forms of interstitial lung diseases.  This book is divided into two sections.  The first section addresses the general aspects of diagnosis and management, including clinical approach, radiographic approach, physiological changes, and classification.  The second section details each individual form of interstitial lung disease.  Organized in an easy to follow format, each disease specific chapter includes tables outlining diagnostic approach, differential diagnosis, disease monitoring, and treatment.  Illustrative cases, replete with high quality HRCT images, bring an added dimension to this outstanding book.

Abstract

Personen met chronisch longlijden kunnen soms thuis behoefte hebben aan extra zuurstoftoediening. In België kan zulke zuurstoftherapie zonder enige beperking door elke arts worden voorgeschreven, en de laatste jaren ziet men een grote stijging van de uitgaven. Bij de organisatie van de therapie zijn verschillende beleidsinstanties en privé- en beroepsorganisaties betrokken, waardoor een globale visie ontbreekt. Het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) pleit voor het herbekijken van de prijzen en voor de minst dure methodes om de zuurstof toe te dienen, vermits ze toch een gelijkwaardig medisch effect hebben. Verder wordt de langdurige therapie best voorbehouden voor patiënten bij wie het wetenschappelijk bewezen is dat ze er baat bij hebben: mensen met zeer ernstige ademnood door COPD, mucoviscidose, hartfalen en bepaalde longziekten.
