BACKGROUND: The pig is one of the most frequently used large animal models for biomedical research, especially in the field of translational research and surgical models. While standard livestock breeds are used in short-term and acute studies, minipig breeds are the preferred breeds in long-term and chronic studies due to their limited growth and body weight. OBJECTIVE: In consideration of the 3R principle (refinement, reduction, replacement) and the increasing demand, the aim of this study was to generate a new, robust, non-specific-pathogen-free minipig breed, the Aachen minipig...

Episodic angio-oedema with eosinophilia (EAE) or Gleich's syndrome is a rare condition characterised by recurrent episodes of oedema and eosinophilia, accompanied by urticaria, fever and weight gain. The presence of ascites has not been reported so far. We report a 21-year-old Caucasian woman who presented with marked ocular oedema and ascites. Laboratory evaluation revealed marked eosinophilia. During the last 3 months, three episodes of facial and neck oedema were reported, which resolved spontaneously over a period of 3-5 days...

REVIEW
Gretchen M Oakley, Richard J Harvey, Valerie J Lund
PURPOSE OF REVIEW: We assess the literature on the pharmacokinetics, indications, important considerations, and effectiveness of long-term, low-dose macrolide antibiotics in chronic rhinosinusitis (CRS). RECENT FINDINGS: The key to effective implementation of macrolide therapy in CRS is appropriate patient selection. Macrolides have demonstrated the most benefit in Th1-mediated non-eosinophilic CRS when used for durations of at least 3 months. Macrolide antibiotics have demonstrated great benefit when used for their anti-inflammatory or immunomodulatory properties, which include the blockage of pro-inflammatory cytokines, such as interleukin (IL)-8 and tumor necrosis factor-α (TNF-α)...

BACKGROUND: Pruritus is still a forgotten aspect of hidradenitis suppurativa (HS) and, to date, has never been adequately studied. OBJECTIVE: The aim of this study was to determine the prevalence, and explore the characteristics, of pruritus in a well-defined cohort of HS patients. SETTING: An academic hospital-based cross-sectional study in The Netherlands. METHODS: A numerical rating scale (NRS, 0-10) was used to determine the prevalence of HS-related itch (NRS score ≥3)...

REVIEW
Anh D Nguyen, Kerry B Dunbar
PURPOSE OF REVIEW: Lymphocytic esophagitis (LE) is an unusual esophageal condition defined by an increased number of lymphocytes in the esophageal epithelium. With few published studies of LE available, it is unclear whether LE is a truly distinct clinical entity or a histological manifestation of other known gastrointestinal disorders. This review summarizes recent studies of lymphocytic esophagitis. RECENT FINDINGS: Studies have suggested that LE may be related to eosinophilic esophagitis (EoE) or a manifestation of gastroesophageal reflux disease (GERD)...

BACKGROUND: Little is known about asthma in the elderly as most studies of this condition have not included this patient group. It is unclear whether leukotriene antagonists benefit older asthmatics. We studied the effect of adding montelukast to the asthma treatment of elderly subjects. METHODS: Twenty-five subjects 65 years old and older with asthma were evaluated at week 0, 1, 5, 9, 13, and 17. Each subject received montelukast 10 mg and placebo each for 8 weeks in a cross-over design...

BACKGROUND: Interleukin-31 (IL-31) is a recently identified cytokine produced by Th2 cells that is involved in the development of atopic dermatitis-induced skin inflammation and pruritus. Its receptor, IL-31RA, is expressed by a number of cell types, including epithelial cells, eosinophils, and activated monocytes and macrophages. To date, however, the regulation of Th2 responses by distinct cell types and tissues expressing IL-31RA has not been well studied. METHODS: In this study, Cry j 2, one of the major allergens of Japanese cedar pollen, was administered to IL-31RA-deficient or wild-type (WT) mice via nasal or intraperitoneal injection for induction of specific Th2 responses...

AIM: To define clinical criteria to differentiate eosinophilic gastrointestinal disorder (EoGD) in the esophagus. METHODS: Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis (EoE), subepithelial eosinophilic esophagitis (sEoE) and eosinophilic esophageal myositis (EoEM), identified by endoscopy, manometry and serum immunoglobulin E levels (s-IgE), in combination with histological and polymerase chain reaction analyses on esophageal tissue samples...

HuR is an RNA-binding protein implicated in immune homeostasis and various cancers, including colorectal cancer. HuR binding to AU-rich elements within the 3' untranslated region of mRNAs encoding oncogenes, growth factors, and various cytokines leads message stability and translation. In this study, we evaluated HuR as a small-molecule target for preventing colorectal cancer in high-risk groups such as those with familial adenomatosis polyposis (FAP) or inflammatory bowel disease (IBD). In human specimens, levels of cytoplasmic HuR were increased in colonic epithelial cells from patients with IBD, IBD-cancer, FAP-adenoma, and colorectal cancer, but not in patients with IBD-dysplasia...

PURPOSE: Content validity is the extent to which a patient-reported outcome measure evaluates the concepts most relevant to a patient's condition and treatment. The St George's Respiratory Questionnaire (SGRQ) has been validated in a range of respiratory conditions. This study evaluated the content validity of the SGRQ in patients with severe asthma. METHODS: A qualitative study, guided by a protocol, which included concept elicitation and cognitive debriefing of the SGRQ, was conducted in patients aged ≥18 years with history of severe asthma and blood eosinophil counts of ≥150/μL (past month) or ≥300/μL (past 12 months)...

INTRODUCTION: Omalizumab is a recombinant humanized IgG1 monoclonal anti-IgE antibody, used for the treatment of severe refractory allergic asthma. However, not all patients with IgE levels within the limits of administration, respond to treatment. The aim of the present study, was to determine clinical and inflammatory characteristics that could predict response to omalizumab. METHODS: We studied retrospectively patients treated with omalizumab as per GINA guidelines in one asthma tertiary referral center...

Sputum basophil numbers are increased in allergic asthmatics, but it is unclear what role airway basophils play in "TH2-low" asthma phenotypes. Using flow cytometry we found that basophils were significantly increased in all asthmatics (n=26) compared with healthy controls (n=8) (p=0.007) with highest levels observed in eosinophilic asthma (EA; median 0.22%, IQR 0.11-0.47%; n=14) compared with non-EA (0.06%, 0.00-0.20%; n=12; p<0.05). In asthmatics, basophils were positively correlated with sputum eosinophils (r=0...

Eosinophils like many myeloid innate immune cells can provide cytokines and chemokines for the activation of other immune cells upon TLR stimulation. When TLR stimulated eosinophils were inoculated i.p. into wildtype mice, NK cells were rapidly recruited and exhibited anti-tumor cytotoxicity. However when mice depleted of CD11c(+) cells were used, a marked decrease in the number of recruited NK cells was observed. We postulated that CpG or LPS from the injected eosinophils could be transferred to host cells, which in turn could recruit NK cells...

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the oesophagus. Recognized as a distinct entity only two decades ago, the emergence of the disease along with the availability of new technologies has rapidly opened new research avenues and outlined the main features of the pathogenesis of EoE. Yet, each advance in our understanding of the disease has raised new questions about the previous consensus. Currently, new subsets of the disease challenge our diagnostic criteria. For instance, it was believed that EoE did not respond to proton pump inhibitor (PPI) therapy; however, it has now been shown that a substantial proportion of EoE patients indeed respond to PPIs...

Mesenchymal stromal cells (MSCs) from different sources have differential effects on lung injury. To compare the effects of murine MSCs from bone marrow (BM), adipose tissue (AD), and lung tissue (LUNG) on inflammatory and remodeling processes in experimental allergic asthma, female C57BL/6 mice were sensitized and challenged with ovalbumin (OVA) or saline (C). Twenty-four hours after the last challenge, mice received either saline (50 µl, SAL), BM-MSCs, AD-MSCs, or LUNG-MSCs (10(5) cells per mouse in 50 µl total volume) intratracheally...

We describe the histopathologic, immunohistochemical, and molecular features of a case of meningoencephalitis in a Thomson's gazelle ( Eudorcas thomsonii) naturally infected with zebra-borne equid herpesvirus 1 (EHV-1) and the implications for the molecular detection of zebra-borne EHV-1. A 4-y-old female Thomson's gazelle was submitted for postmortem examination; no gross abnormalities were noted except for meningeal congestion. Microscopic evaluation demonstrated multifocal nonsuppurative meningoencephalitis with intranuclear eosinophilic and amphophilic inclusion bodies and EHV-9 antigen in neurons...

Three metazoan parasites, a monogenean Hexostoma thynni and two species of copepods Pseudocycnus appendiculatus and Euryphorus brachypterus are known to parasitize the gills of ranched southern bluefin tuna (SBT) and other tuna species. However, there is no detailed information describing the pathological response to infection by these parasites in this species. Wild southern bluefin tuna Thunnus maccoyii (approximately 3 years of age), captured and towed to a grow-out site in the waters immediately south of Port Lincoln, South Australia were subsequently sampled (n = 10) monthly from March until August 2004 during commercial harvest operations...
