Jacques Rottembourg, Guy Rostoker
The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased in France over the last ten years. Despite various facilities offered by the health authorities, PD remains confidential in many private units and some public hospitals. The enthusiasm present at the beginning of this technology, forty years ago, is declining, despite a real improvement in new developments, a real increase in patient survival, today at least similar to that on hemodialysis. Then, the aim of this review is first to give a summary of the principles and practice of patient and staff education and to describe the role of the medical contribution in decision-making...

Immunosuppressant peptide immunocortin for the first time was described in 1993. It corresponds to residues 11-20 of human Ig heavy chain (conserved motif of VH domain). There are no data about production of immunocortin by proteolysis of Ig in vivo. Synthetic immunocortin in concentration ~ 10-9  M suppresses phagocytosis in peritoneal macrophages, ConA-dependent blast transformation of rat lymphocytes, exhibits ACTH-like neurotropic activity and was suggested as a potential drug for treatment of a multiple sclerosis (MS)...

Increasing toxicological and epidemiological studies have demonstrated that ambient particulate matter (PM) could cause adverse health effects including inflammation in the lung. Alveolar macrophages represent a major type of innate immune responses to foreign substances. However, the detailed mechanisms of inflammatory responses induced by PM exposure in macrophages are still unclear. We observed that coarse PM treatment rapidly activated mechanistic target of rapamycin (MTOR) in mouse alveolar macrophages in vivo, and in cultured mouse bone marrow-derived macrophages, mouse peritoneal macrophages, and RAW264...

Most of the peritoneal dialysis patients stop their peritoneal dialysis therapy and transfer to hemodialysis or kidney transplantation. In Japan, most end-stage kidney disease patients select hemodialysis after peritoneal dialysis discontinuation. Peritoneal dialysis catheter will be removed after stopping peritoneal dialysis. If peritoneal dialysis patients suffer from refractory peritonitis or severe tunnel infection, we remove the peritoneal dialysis catheter immediately. However, the causes of peritoneal dialysis discontinuation are ultrafiltration failure or peritoneal membrane dysfunction, and we have to consider the timing of peritoneal dialysis catheter removal...

Peptide immunocortin sequence corresponds to the amino acid residues 11-20 of the variable part of human immunoglobulin G1 (IgG1) heavy chain. Since immunocortin was shown previously to inhibit phagocytosis in peritoneal macrophages and ConA-induced T-lymphocytes proliferation in culture, we suggested that immunocortin administering may be of use for patients with self-immune syndrome. Immunocortin in concentration 10 μM inhibited proliferation of both antigen (myelin)-induced and ConA-induced LN lymphocytes isolated from the lymph nodes of Dark Agouti (DA) rats immunized with chorda shear...

Systemic sclerosis (SSc) is a multisystem autoimmune disorder that is characterized by inflammation and fibrosis in the skin and internal organs. Previous studies indicate that inflammatory cells and cytokines play essential roles in the pathogenesis of SSc; however, the mechanisms that underlie the inflammation-driven development of SSc are not fully understood. In this study, we show that response gene to complement 32 (RGC32) is abundantly expressed in mouse macrophages in the early stage of bleomycin-induced SSc...

BACKGROUND: Encapsulated peritoneal sclerosis (EPS) is a multifactorial chronic intra- abdominal inflammatory disorder affecting the peritoneum diffusely. The aim of this study was to evaluate the rates of EPS in our peritoneal dialysis (PD) population, to perform a general assessment of the clinical presentation and to determine the outcome of affected patients and risk factors. METHODS: The medical records of consecutive 384 patients who started PD therapy between January 2001 and November 2016 were evaluated...

OBJECTIVE: Encapsulating peritoneal sclerosis (EPS) is a serious complication for patients with chronic kidney disease (CKD) who were treated with long-term peritoneal dialysis (PD). The risk of EPS was increased after kidney transplantation. In our study we evaluated risk factors for EPS patients after kidney transplantation who were treated before with PD. MATERIALS AND METHODS: In our study, between January 2008 and August 2015, 47 PD patients (12 had EPS) who underwent kidney transplantation were analyzed...

Patients with chronic kidney disease (CDK) can develop several diseases caused by the renal replacement therapy. Here we report a rare complication of peritoneal dialysis, the encapsulating peritoneal sclerosis (EPS) in which the peritoneal tissue is gradually replaced by fibrous tissue. The patient in question, after late loss of renal graft and conversion to peritoneal dialysis, evolved with multiple hospitalizations for spontaneous bacterial infections, in recent admission, he was diagnosed with sub-occlusive abdomen secondary to the EPS...

Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions...

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...

REVIEW
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...
