RATIONALE: Hypereosinophilic syndrome (HES) is a rare disease characterized by hypereosinophilia and its ensuing organ damage. Cardiac involvement is divided into 3 chronological stages: an acute necrotic stage; a thrombus formation stage; and a fibrotic stage. Infiltration of the myocardium by eosinophilic cells followed by endomyocardial fibrosis is known as "Loeffler endocarditis." PATIENT CONCERNS: We report a case of a 60-year-old man diagnosed with left-sided restrictive cardiomyopathy...

Bee venom (BV) has long been used as anti-inflammatory agent in traditional oriental medicine; however, the effect of BV on chronic rhinosinusitis (CRS) is not commonly studied. The aim of the present study was to determine the anti-inflammatory effect of BV on an allergic CRS mouse model. An allergic CRS mouse model was established following the administration of ovalbumin with Staphylococcus aureus enterotoxin B (SEB) into the nose. A total of 0.5 or 5 ng/ml of BV were intranasally applied 3 times a week for 8 weeks...

Propofol, an intravenous anesthetic agent widely used in clinical practice, is the preferred anesthetic for asthmatic patients. This study was designed to determine the protective effect and underlying mechanisms of propofol on airway inflammation in a mast cell-dependent mouse model of allergic asthma. Mice were sensitized by ovalbumin (OVA) without alum and challenged with OVA three times. Propofol was given intraperitoneally 0.5 h prior to OVA challenge. The inflammatory cell count and production of cytokines in the bronchoalveolar lavage fluid (BALF) were detected...

BACKGROUND: Matrix metalloproteinases (MMPs) 2 and 9 are zinc- and calcium-dependent endopeptidases involved in the breakdown and reconstitution of extracellular matrix under both physiological and pathological conditions. Mucosal MMP-2 and -9 activities have been reported to be upregulated in the intestine of humans with inflammatory bowel disease (IBD), and in animal models of IBD. However, their involvement in the pathogenesis of canine chronic enteropathies (CE) is unknown. This study investigated mucosal pro- and active MMP-2 and -9 activities in dogs with CE and healthy dogs using gelatin zymography, and also to determine the association of their activities in dogs with CE with the canine IBD activity index (CIBDAI), histopathologic findings, the clinical outcome, and hypoalbuminemia...

AIMS: The diagnosis of IgG4-related disease (IgG4-RD) requires a multidisciplinary approach, in which histology plays an important role. Although a diagnosis was previously established using surgically resected specimens, there is increasing clinical demand to diagnose this systemic condition by biopsies. The present study aimed to elucidate how useful transbronchial lung biopsies (TBLBs) are for this diagnostic purpose. METHODS AND RESULTS: The study cohort consisted of 20 consecutive patients diagnosed with IgG4-RD in other organs who underwent TBLBs for potential pulmonary involvement...

Granulomas are responses to persistent nonliving bodies or pathogens, centrally featuring specialized macrophage forms called epithelioid and multinucleated giant cells. The larval stages of the cestode parasites of the taeniidae family (Taenia, Echinococcus) develop for years in fixed tissue sites in mammals. In consequence, they are targets of granulomatous responses. The information on tissue responses to larval taeniids is fragmented among host and parasite species, and scattered over many decades. We attempt to draw an integrated picture of these responses in solid tissues...

Strictures of the small intestine have been attributed many causes of Crohn's disease, nonsteroidal anti-inflammatory drugs, neoplastic, post-surgical, and corrosive ingestion. Opium as a cause of small intestine strictures has not been described. Six cases of opium addicts diagnosed with small intestine strictures were selected after excluding the possible etiology of strictures. Investigations like upper gastrointestinal endoscopy, colonoscopy (in patients with small intestinal obstruction), barium meal follow-through, and histopathology of strictures were done in all patients...

Chronic rhinosinusitis is a heterogeneous group of inflammatory diseases with significant annual costs for the health care system. To date, there is no distinct signaling pathway known that explains the entire process from the beginning to tissue transformation. Due to the diversity of chronic rhinosinusitis, no uniform treatment has yet been developed. With a focus on chronic rhinosinusitis with nasal polyps (CRSwNP), molecular biologic gene expression studies have been performed to identify specific characteristics of nasal polyps that might allow the development of new therapeutic procedures...

Background: A prominent pathological feature of neuromyelitis optica spectrum disorders (NMOSD) is markedly greater eosinophilic infiltration than that seen in other demyelinating diseases, like multiple sclerosis (MS). Eosinophils express the chemokine receptor CCR3, which is activated by eotaxins (CCL11/eotaxin-1, CCL24/eotaxin-2, CCL26/eotaxin-3) and CCL13 [monocyte chemoattractant protein (MCP)-4]. Moreover, CCL13 is part of the chemokine set that activates CCR2. The present study aimed to evaluate plasma levels of eotaxins (CCL11, CCL24, and CCL26) and MCPs (CCL13, CCL2, CCL8, and CCL7) in patients with NMOSD during remission...

An allergic reaction occurs when the immune system overreacts to harmless substance called allergen that gains access to the body. Food allergy is a hypersensitive immune reaction to food proteins and the number of patients with food allergy has recently increased. Aloe Vera is used for wellness and medicinal purposes. In particular, Aloe vera has been reported to enhance immunity. However, the effect of Aloe vera on food allergy is not yet known. In this study, we investigated the effects of processed Aloe vera gel (PAG) containing low molecular weight Aloe polysaccharide (AP) on ovalbumin (OVA)-induced food allergy in mice...

Inflammatory myofibroblastic tumors (IMT) of the lung, first reported in 1939, are considered a subset of inflammatory pseudo -tumors. They are a distinctive lesions composed of myofibroblastic spindle cells accompanied by an inflammatory infiltrate of plasma cells, lymphocytes, and eosinophils. IMTs may be benign, invade surrounding structures, undergo malignant transformation, recur or may even metastasize. They can occur due to a genetic mutation or can occur secondary to infectious or autoimmune diseases...

BACKGROUND: The normal content of eosinophils in the adult duodenum remains undefined. Therefore, there is no foundation for evidence-based criteria to diagnose eosinophilic duodenitis. AIM: This study aimed at: (1) establishing the range of the eosinophil density in the mucosa of the duodenum of normal adults, and (2) determining the biopsy-based prevalence of isolated eosinophilic duodenitis in a large population of adults. METHODS: We counted intact eosinophils in three separate high-power fields (hpf area = 0...

Cocaine is a commonly abused recreational drug in the United States. An adult man developed non-specific pleuritic chest pain, pharyngitis and odynophagia after inhaling cocaine. Initial laboratory results revealed eosinophilia. Bronchoalveolar lavage also showed eosinophilia in the lavage fluid. These findings suggested the diagnosis of eosinophilic pneumonia. Chest imaging revealed scattered bilateral opacities and interstitial infiltrates. After initiation of systemic corticosteroids, the patient reported symptomatic resolution and radiographic clearance was achieved at 2 months follow up...

The NF-κB transcription factor subunit RelB is important for the full activation of conventional dendritic cells (cDCs) during T-cell-dependent immune responses. Although the number of splenic DCs is greatly reduced in RelBnull mice, the cause and consequences of this deficiency are currently unknown. To circumvent the impact of the pleiotropic defects in RelBnull mice we used a reporter model for RelB expression (RelBKatushka mice) and conditionally deleted RelB in DCs (RelBCD11c-Cre mice). Thereby, we can show here that RelB is essential for the differentiation of a CD117+ CD172a+ cDC subpopulation which highly expresses RelB...

Korean red pine (Pinus densiflora) bark has been traditionally used in Korea and other parts of East Asia to relieve inflammatory diseases. Although many studies using P. densiflora bark have been reported, its effect on atopic dermatitis (AD) has not been elucidated. Thus, we investigated whether the P. densiflora bark extract (PBE) has potential to attenuate AD symptoms and elucidated the molecular mechanism. Oral administration of PBE to mice with 2,4-dinitrochlorobenzene (DNCB)-induced AD lessened dermatitis scores and scratching behavior and significantly reduced measures of epidermal thickness, infiltration of mast cells and eosinophils, levels of immunoglobulin E (IgE), and IgG1 /IgG2a ratio in serum...
