In animal studies, intravenous continuous infusion or peritoneal injection of sphingosine-1-phosphate (S1P) has been shown to decrease chemotherapy- and radiotherapy-induced apoptosis on primordial follicles. Although a long-acting oral form of an S1P analogue (FTY720, fingolimod) has been recently developed and utilized in women with multiple sclerosis, there are no data exploring its ability to avoid spontaneous follicle apoptosis. Thirty 10-month-old female rats were randomly assigned to 3 groups to investigate whether fingolimod would be able to decrease the spontaneous ovarian follicle apoptosis ratio...

Emília Mácsai, István Kiss
The significance of peritoneal dialysis in kidney replacement therapy is expected to increase, so it is important to reconsider glucose exposure to minimize the adverse effects. The first step was to develop biocompatible modern PD solutions to reduce the local and systemic adverse effects of current conventional glucose-based ones. According to the limited clinical experience, there are no clear data on better clinical outcome. Besides this there is a suspected theoretical correlation between development of encapsulating peritoneal sclerosis and chronic local irritation of peritoneal surface by glucose...

REVIEW
Robert H Young
Sex cord-stromal tumours of the ovary include many of the most morphologically intriguing ovarian neoplasms and albeit many of them are rare, they factor into the differential diagnosis more often than their frequency might suggest. The most common malignant form, the adult granulosa cell tumour, may grossly simulate various surface epithelial neoplasms. Microscopically, confusion with endometrioid carcinoma may occur because the cords and microfollicles of the granulosa cell tumour may be mimicked by endometrioid carcinoma and the latter may have pale nuclei with nuclear grooves...

Encapsulating peritoneal sclerosis (EPS), treated with surgical enterolysis as a final option, may become refractory to surgical intervention due to intraperitoneal complications. We report the case of a 59-year-old man presenting with EPS who underwent enterolysis at the age of 50, following 15 years of peritoneal dialysis (PD) and peritonitis. During the patient's first surgery, complete surgical enterolysis could not be performed due to severe intestinal adhesions with a deteriorated/calcified small bowel...

Myeloid cells play an important role in the pathogenesis of multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE). Monocytes, macrophages, and microglia can adopt two distinct phenotypes, with M1-polarized cells being more related to inflammation and autoimmunity while M2-polarized cells contribute to tissue repair and anti-inflammatory processes. Here, we show that deletion of the mineralocorticoid receptor (MR) in bone marrow-derived macrophages and peritoneal macrophages caused their polarization toward the M2 phenotype with its distinct gene expression, altered phagocytic and migratory properties, and dampened NO production...

Peritoneal dialysis (PD) has been an attractive treatment for end-stage kidney disease. Long-term exposure to the PD solution creates functional and morphological alterations, and these alterations diminish the efficacy of PD. It is important to establish an evaluation of the changes in PD patients and strategies for the prevention of PD damage and encapsulating peritoneal sclerosis (EPS). We determined the relationship between clinical findings and macroscopic morphological findings by laparoscopy in patients receiving PD...

Regulation of inflammation in intestinal mesothelial cells in the abdominal cavity is important for the pathogeny of clinical conditions, such as postoperative ileus, peritonitis and encapsulating peritoneal sclerosis. Here we have examined the inflammatory effect of lipopolysaccharide (LPS) and the anti-inflammatory effect of nicotinic acetylcholine receptor stimulation in rat intestinal mesothelial cells. LPS upregulated mRNA expression of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1) and inducible nitric oxide synthase (iNOS)...

OBJECTIVES: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disease that causes muscle weakness with respiratory and swallowing dysfunction, eventually leading to death. Permanent enteral feeding is indicated in almost all patients. A percutaneous endoscopic gastrostomy (PEG) tube is considered the first choice, usually performed under conscious sedation (intravenous midazolam). Guidelines are very cautious with respect to sedation in ALS because of the risk for respiratory complications...

PURPOSE: C-reactive protein (CRP) is a useful biomarker for prediction of long-term outcomes in patients undergoing chronic dialysis. This observational cohort study evaluated whether the time-averaged serum high-sensitivity CRP (HS-CRP) level was a better predictor of clinical outcomes than a single HS-CRP level in patients undergoing peritoneal dialysis (PD). PATIENTS AND METHODS: We classified 335 patients into three tertiles according to the time-averaged serum HS-CRP level and followed up regularly from January 2010 to December 2014...

The aim of this work was to assess the state of the fallopian tubes in women with urogenital chlamydia (UC) and infertility. 344 women 18-49 y.o with infertility have been investigated. UC was detected in 133 of them -38.7%, (main group), UC was absent in 211 (61.3%) patients (comparision group). In the main group prevailed the tubal or tubal peritoneal factor of infertility (51.9% versus 19.4% in the comparison group, p<0.001). UC in women in the main (62.4%) was in the form of mixed infection. Obstruction of the fallopian tubes and adhesions in the pelvic region were more often detected in patients of the main group (p<0...

A negative correlation between the geographical distribution of autoimmune diseases and helminth infections has been largely associated in the last few years with a possible role for such type of parasites in the regulation of inflammatory diseases, suggesting new pathways for drug development. However, few helminth-derived immunomodulators have been tested in experimental autoimmune encephalomyelitis (EAE), an animal model of the human disease multiple sclerosis (MS). The immunomodulatory activities of Taenia crassiceps excreted/secreted products (TcES) that may suppress EAE development were sought for...

BACKGROUND: Encapsulating peritoneal sclerosis (EPS) is the most severe complication of peritoneal dialysis (PD). Several retrospective reports published between 2007 and 2009 have suggested an increasing incidence of EPS occurring after kidney transplantation. We conducted a prospective observational study to determine the incidence of post-transplantation EPS and identify possible risk factors. METHODS: Consecutive PD patients undergoing kidney transplantation between 2009 and 2013 were included...

Cardiovascular mortality in the end-stage renal disease (ESRD) population remains the leading cause of death. Targeting traditional cardiovascular risk factors has proven unsuccessful in this patient population, and therefore attention has turned to risk factors related to chronic kidney disease (CKD). The toxicity of high-glucose peritoneal dialysis (PD) solutions has been well documented. The breakdown of glucose into glucose degradation products (GDP) and advanced glycation end-products (AGE) has the ability to alter cell viability and cause premature apoptosis and is strongly correlated with interstitial fibrosis and microvascular sclerosis...

Encapsulating peritoneal sclerosis (EPS) is a potentially devastating complication of peritoneal dialysis (PD). Diagnosis is often delayed due to the lack of effective and accurate diagnostic tools. We therefore examined peritoneal effluent for potential biomarkers that could predict or confirm the diagnosis of EPS and would be valuable in stratifying at-risk patients and driving appropriate interventions. Using prospectively collected samples from the Global Fluid Study and a cohort of Greek PD patients, we utilized 2D SDSPAGE/ MS and iTRAQ to identify changes in the peritoneal effluent proteome from patients diagnosed with EPS and controls matched for treatment exposure...

Skin fibrosis in systemic sclerosis (SSc) is accompanied by attrition of dermal white adipose tissue (dWAT) and reduced levels of circulating adiponectin. Since adiponectin has potent regulatory effects on fibroblasts, we sought to assess adiponectin signaling in SSc skin biopsies, and evaluate fibrosis in mice with adiponectin gain- and loss-of-function mutations. Furthermore, we investigated the effects and mechanism of action of agonist peptides targeting adiponectin receptors in vitro and in vivo. We found that adiponectin pathway activity was significantly reduced in a subset of SSc skin biopsies...

The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased markedly in the Netherlands in the last 15 years. Consequently, the knowledge of nephrologists and nursing staff on PD has declined leading to a negative spiral in which loss of experience resulted in loss of enthusiasm to offer PD to patients and also in less interest in the new PD developments. All these changes took place while the results of PD improved and patient survival was at least similar to that on haemodialysis...

Encapsulating peritoneal sclerosis is a rare but devastating complication of long-term peritoneal dialysis with a high mortality rate. The incidence is between 0.5 and 2.5%, decreasing with time. PSE is defined as a clinical syndrome with signs of gastrointestinal obstruction, inflammation parameters, radiological and macroscopic changes. The duration of treatment and the cessation of peritoneal dialysis are the main risks. About 75% occured in patients on hemodialysis or after kidney transplantation. Morphological alterations are disappearance of mesothelial layer, submesothelial fibrosis, interstitial sclerosis and vasculopathy...

BACKGROUND: Peritoneal injury is an important cause of technical failure of long-term peritoneal dialysis (PD). Encapsulating peritoneal sclerosis (EPS) is a severe complication of long-term PD with potentially life threatening consequences. CD147 is a glycoprotein with diverse functions including modulation of extracellular matrix via induction of matrix metalloproteinases, cell adhesion, and regulation of immune reactions. We hypothesized that CD 147 plays a role in the peritoneal cavity...
