As a rare complication in patients on peritoneal dialysis (PD), increase of eosinophil (peritoneal dialysate fluid [PDF] eosinophilia), including eosinophilic peritonitis, was observed in PDF. The majority of eosinophilic peritonitis cases are detected during the early phase of PD induction. However, the frequency of and mechanisms underlying PDF eosinophilia remain unclear. We therefore investigated the frequency of PDF eosinophilia and what mechanisms, specifically complement activation, might contribute to its occurrence...

Sialic acid-binding Ig-like lectin 8 (Siglec-8) is expressed on the surface of human eosinophils, mast cells, and basophils-cells that participate in allergic and other diseases. Ligation of Siglec-8 by specific glycan ligands or antibodies triggers eosinophil death and inhibits mast cell degranulation; consequences that could be leveraged as treatment. However, Siglec-8 is not expressed in murine and most other species, thus limiting preclinical studies in vivo. Based on a ROSA26 knock-in vector, a construct was generated that contains the CAG promoter, a LoxP-floxed-Neo-STOP fragment, and full-length Siglec-8 cDNA...

Acute appendicitis is one of the most common abdominal emergencies worldwide. Uncomplicated appendicitis (UA), which does not involve perforation or peritonitis, has recently been treated with antibiotic therapy. Here, we report a case of acute eosinophilic appendicitis (AEA) that simulated UA and did not respond to antibiotic therapy. A 20-year-old Japanese woman emergently presented with the chief complaint of pain at the right iliac fossa. CT showed only swelling of the appendix. She was diagnosed with UA, and she received antibiotic therapy initially...

Ovarian cancer is frequently diagnosed as peritoneal carcinomatosis. Unlike other tumor locations, the peritoneal cavity is commonly exposed to gut-breaching and ascending genital microorganisms and has a unique immune environment. IL-33 is a local cytokine that can activate innate and adaptive immunity. We studied the effectiveness of local IL-33 delivery in the treatment of cancer that has metastasized to the peritoneal cavity. Direct peritoneal administration of IL-33 delayed the progression of metastatic peritoneal cancer...

The acute abdomen with its many clinical aspects is not a condition that eludes pregnancy; acute appendicitis being the most frequently incriminated, but when it comes to its complication - peritonitis and the pregnant is a teenager, the cases cited in the literature are quite rare. We present the case of a 15-year-old teenager pregnant within 24 weeks admitted from the emergency department with the diagnosis of acute abdomen and operated for generalized peritonitis due to a perforated appendicitis. The microscopic analysis of the specimen indicated the presence of ulceration and extensive and deep and necrosis of the appendicle wall, the residual structures being dissected by a predominantly polymorphonuclear leukocytes inflammatory infiltrate associated with eosinophilic fibrinous deposits...

BACKGROUND: Abdominal ascites is a common problem in general surgery. The causes include parasitic diseases, tuberculosis, malignancies, hypoalbuminemia, abdominal inflammatory diseases, and peritonitis. Eosinophilic gastroenteritis (EG) has also been reported to be an infrequent cause. To our knowledge, most instances of abdominal ascites from EG have occurred in adults and been reported by physicians or gastroenterologists. Herein, we report a small series of children who presented with eosinophilic ascites from a surgeon's perspective...

Multilocular peritoneal inclusion cysts are mesothelial tumor-like lesions with or without small foci of florid papillary mesothelial hyperplasia that might simulate serous epithelial papillary lesions or well-differentiated papillary mesothelioma (WDPM) of the peritoneum. The papillary cores in papillary mesothelial hyperplasia and in WDPM display a variety of different histomorphologic features. To our knowledge, collagenous spherulosis in WDPM was not previously described or illustrated in the literature...

Noninvasive ovarian low-grade serous tumors [atypical proliferative serous tumor (APST)/serous borderline tumor] appear to progress to invasive low-grade serous carcinoma (LGSC) at a low but regular rate. The underlying biology of this phenomenon is unknown. We studied 18 patients with 30 ovarian tumors (12 bilateral), including APST, noninvasive LGSC and invasive LGSC, who also had low-grade serous carcinomatosis. Tumors were evaluated for microinvasion (usual eosinophilic cell type), microinvasive carcinoma (<5 mm invasion of micropapillary nests), and overt carcinoma (≥5 mm invasion of micropapillary nests)...

An allergic reaction is a potentially fatal hypersensitivity response caused by mast cell activation, particularly histamine and lipid mediators. Histamine release caused by reaction to drugs is considered a pseudo-allergic reaction. Quercetin is known for its anti-allergic immune effect. However, at present, its anti-pseudo-allergic effect and its mechanism are less investigated. Therefore, the purpose of this study was to evaluate the anti-pseudo-allergic effect of Quercetin in vivo and to explore the mechanism in vitro...

CD300a is an inhibitory receptor for mast cells and eosinophils in allergic inflammation (AI); however, the spatiotemporal expression of CD300a and its potential roles in the resolution of AI are still to be determined. In this study, employing a mouse model of allergic peritonitis, we demonstrate that CD300a expression on peritoneal cells is regulated from inflammation to resolution. Allergic peritonitis-induced CD300a-/- mice had a rapid increase in their inflammatory cell infiltrates and tryptase content in the peritoneal cavity compared with wild type, and their resolution process was significantly delayed...

BACKGROUND: Eosinophils are a therapeutic target in asthmatic patients, and GM-CSF has been suggested to control various aspects of eosinophil biology, including development, function, and survival. However, to date, the role of GM-CSF signaling in eosinophils in vivo is largely unclear. OBJECTIVE: We sought to elucidate the role of GM-CSF signaling in asthmatic inflammation. METHODS: Wild-type and GM-CSF receptor α (Csf2ra)-deficient mice reconstituted with Csf2ra-proficient alveolar macrophages were subjected to different models of airway inflammation to evaluate the effect of GM-CSF signaling deficiency on asthmatic inflammation in general and on eosinophils in particular...

Pythium insidiosum, an aquatic oomycete, causes chronic lesions in the skin and digestive tract of multiple species. A captive-bred Bactrian camel ( Camelus bactrianus) showed clinical signs of lethargy and weight loss in a clinical course of 30 days, with no response to treatment. At necropsy, the abdominal cavity had approximately 32 L of a yellow, turbid fluid with fibrin. The third compartment of the stomach (C-3) showed a focal area of rupture covered with fibrin. Close to this area, the C-3 wall was thickened and firm, demonstrating irregular, yellow, and friable areas on cut surface (kunkers)...

Peritoneal dialysis (PD)-related peritonitis is recognized as a common complication of peritoneal dialysis. Eosinophilic peritonitis is a rare type of non-infection PD-related peritonitis. Eosinophilic peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients was first reported in 1967. The cause of eosinophilic peritonitis is obscure, however it may be related to some etiologies: (1) hypersensitivity to PD materials, including catheter or dialysate; (2) bacteria, fungal or mycobacterium tuberculosis infection...

Clear cell variant of epithelioid mesothelioma is an extremely rare tumor with only isolated cases reported so far in the peritoneum. Here, we report a case of peritoneal epithelioid mesothelioma, clear cell variant, in a 63-year-old female patient with a novel VHL gene mutation and an unusual indolent clinical course. The patient, who has no clinical history of asbestos exposure, presented with a 27.2 cm upper abdominal mass and a 5.5 cm liver lesion. Retrospective review of the patient's abdominal CT scan 4 years ago showed two small abdominal lesions that were felt clinically to represent hemangiomas...

According to Klein's classification system, the symptomatology of eosinophilic gastroenteritis (EG), a rare disease, differs based on the affected tissue layer. Patients with subserosal EG often have peritoneal effusion. Hemorrhagic ascites due to EG is extremely rare and has not been reported in the literature. Here, we report a 57-year-old woman with EG and massive hemorrhagic ascites. Laboratory investigations showed elevated peripheral eosinophils with significant eosinophilia (65.6%). Ultrasonography showed massive abdominal ascites...

BACKGROUND: Sepsis is a life-threatening disease mediated by profound disturbances in systemic inflammatory response to infection. IL-33 is multifunctional regulator of numerous aspects of innate and adaptive immune response. The aim of this article was to further evaluate the role of IL-33 receptor (ST2) in different pathways of innate immunity during early polymicrobial sepsis. METHODS: Polymicrobial sepsis was induced using cecal ligation and puncture (CLP) model in ST2 deficient (ST2-/- ) and wild type BALB/c mice...

During Fasciola hepatica infection, the parasite has the capability to modulate the host immune response towards a non-protector Th2 type instead of Th1. This type of immune response is closely related to the alternative activation of macrophages (M2 profile) as has been shown in vivo in murine models. In this study, an experiment was carried out in order to evaluate the expression of CD68, CD14, CD206 and iNOS in cells present in the peritoneal fluid of sheep during early stages of infection with F. hepatica (1, 3, 9 and 18 days post-infection, dpi) by immunocytochemistry...

Transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI) is a receptor for the TNF superfamily cytokines, B cell-activating factor (BAFF), and A proliferation-inducing ligand (APRIL). Here, we demonstrate that TACI-deficient mice subjected to high-fat diet (HFD) are protected from weight gain and dysregulated glucose homeostasis. Resistance to HFD-induced metabolic changes in TACI-deficient mice does not involve TACI-mediated adipogenesis. Instead, accumulation of M2 macrophages (Mϕs), eosinophils, and type 2 innate lymphoid cells in visceral adipose tissue (VAT) is implicated in the protection from obesity-induced assaults...
