Peritonitis is the main complication of peritoneal dialysis (PD) and also an important factor for raising the cost of the method to the level of hemodialysis. Associated with PD, peritonitis is responsible for the increase of morbidity and mortality of the procedure and, at the same time, the main cause of the technique failure. Severe and prolonged peritonitis or repeated episodes of peritonitis lead to ultrafiltration failure. Peritonitis treatment should aim for a rapid remission of inflammation in order to preserve the peritoneal membrane functional integrity. The treatment of PD peritonitis consists mainly of antibiotic therapy, surgical intervention not being usually required. However, it is of outmost importance to differentiate the so-called "catheter related" peritonitis from secondary peritonitis due to visceral lesions, in which the surgical treatment comes first. The confusion between secondary and "catheter related" peritonitis may lead to serious errors in choosing the correct treatment, endangering the patient's life. The differential diagnosis between a refractory or secondary peritonitis in a peritoneal dialyzed patient may be very difficult. In front of a refractory PD peritonitis, surgical exploration must not be delayed. Also we have to keep in mind that the aim of peritonitis treatment is the saving of the peritoneal membrane and not the catheter.

To evaluate the frequency of urinary peritonitis in children and to highlight its terms of management in a country with limited resources. We retrospectively observed nine case reports of urinary peritonitis collected in surgical reanimation service at the CHU of Antananarivo, from 1st January 2009 to 31 December 2012. Urinary peritonitis accounts 0.5% of all pediatric abdominal emergencies and 5% of pediatric urological emergencies collected in our service during study period. Three etiologies were traumatic bladder rupture, one bladder iatrogenic rupture, four secondary to obstructive uropathy and one other after cystolithotomy. We found a new case of posttraumatic transverse rupture of the bladder neck. Among obstructive uropathy observed, there were two cases of posterior urethral valves and two cases of ureteralpelvic junction obstruction. Clinical expression was dominated by fever, with abdominal distention and defense. In majority of cases, etiological diagnosis was made intraoperatively. The surgical treatment by laparotomy was performed under cover of systemic antibiotic therapy. Evolution was complicated with sepsis in three cases and acute renal failure in both cases. Surgical follow-up without complication were observed in four cases. A child has died to septic shock and multivisceral failure. Unlike urinary ascites resulting a transperitoneal extravasation of urine, uroperitoneum was a fistula between adominal cavity and content of the urinary tract. Urinary ascites was a rare cause of peritonitis. In contrast, uroperitoneum caused peritonitis quickly. Urinary peritonitis was a rare entity but severe prognosis in children. In majority of cases, etiological diagnosis was made intraoperatively. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Full Text Available Abdominal compartment syndrome with increased abdominal pressure resulted in multi-organ dysfunctions can be lethal in children. The open abdomen procedure intentionally leaves the abdominal cavity open in patients with severe abdominal sepsis and abdominal compartment syndrome by temporarily relieving the abdominal pressure. We reported our experience of open abdomen procedure in successfully treating a 4-year old boy with abdominal compartment syndrome caused by severe fungal peritonitis and sepsis after gastric perforation.

, with groups 3 and 4 having the longest duration of treatment, accompanied by a higher percentage of antibiotic switch. Increased resistance to cephradine was found for coagulase-negative Staphylococcus. ♦ Conclusions: Peritonitis rates declined significantly over the years because of several changes in PD treatment. However, the need to change the initial antibiotic increased because of diminished antibiotic susceptibility rates over time. Nevertheless, the cure rate was high and remained stable during the entire period analyzed, and the death rate remained low. Consequently, peritonitis is a manageable complication of PD that cannot be considered a contraindication to this mode of renal replacement therapy. PMID:24584620

Hepatic VOD (veno-occlusive disease) is a serious complication of HSCT (hematopoietic stem cell transplantation) and has historically been associated with high mortality. This obstruction to hepatic flow often results in fluid collections in the peritoneal and pleural cavities. Catheter placement to drain ascites or pleural fluid may reduce intra-abdominal hypertension and/or improve respiratory parameters. The safety of these interventions among critically ill, immunocompromised children is unknown. Among 32 HSCT recipients (2000-2012) with severe VOD, we assessed the primary outcome of procedural complication from peritoneal drain placement. Twenty-four (75%) patients underwent peritoneal drain placement. No patient sustained visceral perforation or hemorrhage with drain placement. Overall mortality was 47% (n = 15). The procedure was not associated with increased overall mortality (p > 0.99). Eight (25%) peritoneal drains required replacement for malfunction. Of 24 patients with peritoneal drains, one (4%) patient had a positive culture from ascitic fluid. Eight (25%) patients underwent pleural drain placement. No pleural drain-related procedural complication or infection occurred. Four (50%) of the eight patients with pleural drains had de-escalation in oxygen requirement at drain removal, compared to time of placement. In this study, peritoneal and pleural drains were safe interventions for children with severe VOD. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

♦ Peritonitis is a major complication of peritoneal dialysis (PD) and is associated with significant morbidity and mortality. Early empirical antibiotic therapy is recommended, with the choice of agents guided by local resistance patterns. As routine use of specific antimicrobial agents can drive resistance, regular assessment of causative organisms and their susceptibility to empirical therapy is essential. ♦ We conducted a retrospective review of all PD peritonitis cases and positive PD fluid cultures obtained over a 5-year period in Western Australia following the introduction of a statewide protocol for the initial management of PD peritonitis with intraperitoneal vancomycin and gentamicin. ♦ The incidence of PD peritonitis decreased from 1 in 16 patient months (0.75/year at risk) to 1 in 29 patient months (0.41/year at risk) over the 5 years. There were 1,319 culture-positive samples and 1,069 unique isolates identified. Gram-positive bacteria accounted for 69.9% of positive cultures, with vancomycin resistance averaging 2% over the study period. Gram-negative bacteria accounted for 25.4% of positive cultures, with gentamicin resistance identified in an average of 8% of organisms. No increase in antimicrobial resistance to vancomycin or gentamicin occurred over the 5 years and there was no change in the proportion of gram-positive (69.9%), gram-negative (25.4%) or fungal (4.4%) organisms causing PD peritonitis. ♦ Over time, the peritonitis rates have dramatically improved although the profile of causative organisms remains similar. Empirical treatment of PD peritonitis with intraperitoneal vancomycin and gentamicin remains efficacious, with high levels of susceptibility and no evidence that the introduction of this statewide empirical PD peritonitis treatment protocol is driving resistance to these agents.

Full Text Available Preservation of peritoneal cavity homeostasis and peritoneal membrane function is critical for long-term peritoneal dialysis (PD treatment. Several microRNAs (miRNAs have been implicated in the regulation of key molecular pathways driving peritoneal membrane alterations leading to PD failure. miRNAs regulate the expression of the majority of protein coding genes in the human genome, thereby affecting most biochemical pathways implicated in cellular homeostasis. In this review, we report published findings on miRNAs and PD therapy, with emphasis on evidence for changes in peritoneal miRNA expression during long-term PD treatment. Recent work indicates that PD effluent- (PDE- derived cells change their miRNA expression throughout the course of PD therapy, contributing to the loss of peritoneal cavity homeostasis and peritoneal membrane function. Changes in miRNA expression profiles will alter regulation of key molecular pathways, with the potential to cause profound effects on peritoneal cavity homeostasis during PD treatment. However, research to date has mainly adopted a literature-based miRNA-candidate methodology drawing conclusions from modest numbers of patient-derived samples. Therefore, the study of miRNA expression during PD therapy remains a promising field of research to understand the mechanisms involved in basic peritoneal cell homeostasis and PD failure.

To compare the CT findings of peritoneal tuberculosis (PT) and peritoneal carcinomatosis (PC) based on the morphologic features of the peritoneum and assess the relationship between the degree of peritoneal thickness and the severity of omental infiltration in PT and PC. We retrospectively reviewed the CT findings of 15 patients with PT and 14 with PC. We checked morphologic changes of the peritoneum as seen on CT, for the following points: 1) the presence of peritoneal change: 2) the pattern of any change-diffuse thickening, plaque or nodularity, combined thickening (diffuse and plaque, or nodularity) 3) the degree of thickness on the whole peritoneum - mild (grossly definite, but not more than 3mm), moderate (more than 3mm); 4) the presence of irregularity on the peritoneal surface. We also evaluated the significance of the relationship between peritoneal thickness and omental infiltration in both disease entities. The degree of omental infiltration was described as follows : grade 1 (no change or focal smudge pattern); grade 2 (diffuse smudge), grade 3 (omental cake regardless extent). Peritoneal change was seen in 12 of 15 PT patients and in 7 of 14 PC patients. In all 12 PT patients, the pattern of change was diffuse thickening, and among the seven PC patients, there was diffuse thickening in one, plaque or nodular thickening in four, and combined thickening in two. In PT patients, the degree of thickness on the whole peritoneum was mild in six and moderate in six, and in PC patients it was mild in two and moderate in one. An irregular peritoneum surface was seen in one patient with PT and in two with PC. The degree of omental infiltration in PT was grade 1 in four patients, grade 2 in six and grade 3 in five. In PC, it was grade 1 in six patients, grade 2 in two and grade 3 in six. Smooth diffuse thickening of the peritoneum was seen in 11 of 15 PT cases and in one of 14 PC (P 0.5). In PT and PC different CT findings based on peritoneal morphologic changes

The use of the "peritonitis rate" in the management of patients undergoing peritoneal dialysis is assuming importance in comparing the prowess of facilities, care givers and new innovations. For this to be a meaningful outcome measure, the type of infection (causative pathogen) must have less clinical significance than the number of infections during a time interval. The natural history of Staphylococcus aureus, pseudomonas, and fungal peritonitis would not support that the outcome of an episode of peritonitis is independent of the causative pathogen. Could this concern be extended to other more frequently occurring pathogens? To address this, the Network 9 Peritonitis Study identified 530 episodes of single organism peritonitis caused by a gram positive organism and 136 episodes caused by a single non-pseudomonal gram negative (NPGN) pathogen. Coincidental soft tissue infections (exit site or tunnel) occurred equally in both groups. Outcomes of peritonitis were analyzed by organism classification and by presence or absence of a soft tissue infection. NPGN peritonitis was associated with significantly more frequent catheter loss, hospitalization, and technique failure and was less likely to resolve regardless of the presence or absence of a soft tissue infection. Hospitalization and death tended to occur more frequently with enterococcal peritonitis than with other gram positive peritonitis. The outcomes in the NPGN peritonitis group were significantly worse (resolution, catheter loss, hospitalization, technique failure) compared to coagulase negative staphylococcal or S. aureus peritonitis, regardless of the presence or absence of a coincidental soft tissue infection. Furthermore, for the first time, the poor outcomes of gram negative peritonitis are shown to be independent of pseudomonas or polymicrobial involvement or soft tissue infections. The gram negative organism appears to be the important factor. In addition, the outcome of peritonitis caused by S. aureus

Although laparoscopy is becoming the standard of care for the treatment of colorectal disease, its application in case of postoperative peritonitis is still not widespread. The objective of this article is to evaluate the role of laparoscopy in the management of postoperative peritonitis after elective minimally invasive colorectal resection for malignant and benign diseases. Between April 2010 and May 2016, 536 patients received primary minimally invasive colorectal surgery at our Department. Among this series, we carried out a retrospective study of those patients who, having developed signs of peritonitis, were treated with a laparoscopic reintervention. Patient demographics, type of complication and of the main relaparoscopic treatment, and main outcomes of reoperation were recorded. A total of 20 patients (3.7%) underwent relaparoscopy for the management of postoperative peritonitis, of which exact causes were detected by laparoscopy in 75% as follows: anastomotic leakage (n = 8, 40%), colonic ischemia (n = 2, 10%), iatrogenic bowel tear (n = 4, 20%), and other (n = 1, 5%). The median time between operations was 3.5 days (range, 2-8). The laparoscopic reintervention was tailored case by case and ranged from lavage and drainage to redo anastomosis with ostomy fashioning. Conversion rate was 10% and overall morbidity was 50%. No cases required additional surgery and 30-day mortality was nil. Three patients (15%) were admitted to intensive care unit for 24-hour surveillance. Our experience suggests that in experienced hands and in hemodynamically stable patients, a prompt laparoscopic reoperation appears as an accurate diagnostic tool and an effective and safe option for the treatment of postoperative peritonitis after primary colorectal minimally invasive surgery.

Severe peritonitis causing death is one of the most devastating complications of peritoneal dialysis (PD). Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis.

Aim: Assessment of peritoneal permeability is necessary for successful management of End Stage Renal Disease (ESRD) patients by Continuous Ambulatory Peritoneal Dialysis (CAPD). Twardowski in 1987 described for the first time a method know as Peritoneal Equilibration Test (PET ) to determine peritoneal membrane characteristics. However, this test is not only cumbersome but is associated with several limitations. The objective of this study was to develop an alternative method of assessing the peritoneal permeability and compare this method with the conventional PET. Method: Twenty patients under going regular CAPD were included in this study. Before starting the peritoneal dialysis 370 MBq (10 mCi) 99mTc-DTPA was injected intravenously in the same standard precondition as for PET evaluation. A standard dose of same quantity was kept and used later for calculations. At the end of four hours a dialysate fluid sample (1 ml) was collected and the total dialysis effluent fluid volume was measured. Excretion of 99mTc-DTPA into the dialysate fluid as percentage of injected dose was calculated. Simultaneously standard PET values were recorded for comparison. Results: Peritoneal excretion of 99mTc-DTPA ranged from 8 % to 16 % of the injected dose depending upon the peritoneal membrane permeability. Depending upon the DTPA excretion the patients were divided into 4 groups: High Transporter (15% and above; High Average (12 to 15 %); Low Average (10 to 12%); Low Average (10% and less). When the results were compared with the conventional PET values, a good correlation (r=0.79) could be found. Conclusion: Determining the excretion of 99mTc-DTPA in the dialysate fluid after 4 hrs as percentage of the injected dose is a simple and convenient method to assess the peritoneal membrane permeability and can be used as an alternative technique to conventional PET which is very cumbersome and associated with many limitations

Full Text Available Abstract. Endometriosis is a disease accompanied by development of heterotopic endometrial foci at the peritoneum, proliferation of endothelial cells, and inflammatory reaction. Aiming to specify the dynamics of inflammatory process in endometriosis of different severity, as well as significance of chemokines and cytokines in angiogenesis and inflammation, we determined concentrations of RANTES, IL-8, IP-10, MIG, MCP-1 chemokines, as well as IL-4, IL-6 and IL-10 cytokines in peritoneal fluid from patients by endometriosis. Forty women at reproductive age with an endometriosis have been observed. Among them, endometriosis grade I-II was registered in 20 cases, whereas grade III-IV has been confirmed in 20 women. Twenty-two women without evidence of endometriosis referred to diagnostic laparoscopy for pregnancy planning, comprised a control group. Diagnosis of endometriosis was based upon endoscopic findings and results of histological research. Severity grade of endometriosis was estimated according to R-AFS classification. Sampling of peritoneal fluid was carried out when performing surgical laparoscopies. Concentrations of chemokines and cytokines were determined by flow cytometry techniques, using BD Cytometric Bead Array test kits and FACStrack flow cytometer. The amounts of RANTES in peritoneal fluid were higher in grade I-II endometriosis, in comparison with grade III-IV endometriosis and control samples. Concentrations of IP-10, IL-8, МСР-1, MIG, IL-6, and IL-4 were higher than in control group and correlated with severity of the disease. IL-10 was not detectable in peritoneal fluid of the patients with endometriosis. These results suggest a significant role of the mentioned cytokines and chemokines that may promote invasion of endometrial cells, growth of heterotopic endometrioid locuses, development of vascular bed and induction of inflammatory processes, in development and progression of endometriosis.

♦ Objective: Management of peritoneal dialysis (PD)-associated peritonitis requires timely intervention by experienced staff, which may not be uniformly available throughout the week. The aim of the present study was to examine the effects of weekend compared with weekday presentation on peritonitis outcomes. ♦ Methods: The study, which used data from the Australia and New Zealand Dialysis and Transplant Registry, included all Australian patients receiving PD between 1 October 2003 and 31 December 2008. The independent predictors of weekend presentation and subsequent peritonitis outcomes were assessed by multivariate logistic regression. ♦ Results: Peritonitis presentation rates were significantly lower on Saturdays [0.46 episodes per year; 95% confidence interval (CI): 0.42 to 0.49 episodes per year] and on Sundays (0.43 episodes per year; 95% CI: 0.40 to 0.47 episodes per year) than all other weekdays; they peaked on Mondays (0.76 episodes per year; 95% CI: 0.72 to 0.81 episodes per year). Weekend presentation with a first episode of peritonitis was independently associated with lower body mass index and residence less than 100 km away from the nearest PD unit. Patients presenting with peritonitis on the weekend were significantly more likely to be hospitalized [adjusted odds ratio (OR): 2.32; 95% CI: 1.85 to 2.90], although microbial profiles and empiric antimicrobial treatments were comparable between the weekend and weekday groups. Antimicrobial cure rates were also comparable (79% vs 79%, p = 0.9), with the exception of cure rates for culture-negative peritonitis, which were lower on the weekend (80% vs 88%, p = 0.047). Antifungal prophylaxis was less likely to be co-prescribed for first peritonitis episodes presenting on weekdays (OR: 0.68; 95% CI: 0.05 to 0.89). ♦ Conclusions: Patients on PD are less likely to present with peritonitis on the weekend. Nevertheless, the microbiology, treatment, and outcomes of weekend and weekday PD peritonitis

Pathophysiological Changes to the Peritoneal Membrane during PD-Related Peritonitis: The Role of Mesothelial Cells

Science.gov (United States)

Yung, Susan; Chan, Tak Mao

2012-01-01

The success of peritoneal dialysis (PD) is dependent on the structural and functional integrity of the peritoneal membrane. The mesothelium lines the peritoneal membrane and is the first line of defense against chemical and/or bacterial insult. Peritonitis remains a major complication of PD and is a predominant cause of technique failure, morbidity and mortality amongst PD patients. With appropriate antibiotic treatment, peritonitis resolves without further complications, but in some PD patients excessive peritoneal inflammatory responses lead to mesothelial cell exfoliation and thickening of the submesothelium, resulting in peritoneal fibrosis and sclerosis. The detrimental changes in the peritoneal membrane structure and function correlate with the number and severity of peritonitis episodes and the need for catheter removal. There is evidence that despite clinical resolution of peritonitis, increased levels of inflammatory and fibrotic mediators may persist in the peritoneal cavity, signifying persistent injury to the mesothelial cells. This review will describe the structural and functional changes that occur in the peritoneal membrane during peritonitis and how mesothelial cells contribute to these changes and respond to infection. The latter part of the review discusses the potential of mesothelial cell transplantation and genetic manipulation in the preservation of the peritoneal membrane. PMID:22577250

Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

♦ BACKGROUND: Peritonitis is the most important complication of peritoneal dialysis (PD), and early peritonitis rate is predictive of the subsequent course on PD. Our aim was to calculate the early peritonitis rate and to identify characteristics and predisposing factors in a large nationwide PD provider network in Colombia. ♦ METHODS: This was a historical observational cohort study of all adult patients starting PD between January 1, 2012, and December 31, 2013, in 49 renal facilities in the Renal Therapy Services in Colombia. We studied the peritonitis rate in the first 90 days of treatment, its causative micro-organisms, its predictors and its variation with time on PD and between individual facilities. ♦ RESULTS: A total of 3,525 patients initiated PD, with 176 episodes of peritonitis during 752 patient-years of follow-up for a rate of 0.23 episodes per patient year equivalent to 1 every 52 months. In 41 of 49 units, the rate was better than 1 per 33 months, and in 45, it was better than 1 per 24 months. Peritonitis rates did not differ with age, ethnicity, socioeconomic status, or PD modality. We identified high incidence risk periods at 2 to 5 weeks after initiation of PD and again at 10 to 12 weeks. ♦ CONCLUSION: An excellent peritonitis rate was achieved across a large nationwide network. This occurred in the context of high nationwide PD utilization and despite high rates of socioeconomic deprivation. We propose that a key factor in achieving this was a standardized approach to management of patients. Copyright © 2017 International Society for Peritoneal Dialysis.

Timely identification of patients in need of an intervention for abdominal sepsis after initial surgical management of secondary peritonitis is vital but complex. The aim of this study was to validate a decision tool for this purpose and to evaluate its potential to guide post-operative management. A prospective cohort study was conducted on consecutive adult patients undergoing surgery for secondary peritonitis in a single hospital. Assessments using the decision tool, based on one intra-operative and five post-operative variables, were performed on the second and third post-operative days and when the patients' clinical status deteriorated. Scores were compared with the clinical reference standard of persistent sepsis based on the clinical course or findings at imaging or surgery. Additionally, the potential of the decision tool to guide management in terms of diagnostic imaging in three previously defined score categories (low, intermediate, and high) was evaluated. A total of 161 assessments were performed in 69 patients. The majority of cases of secondary peritonitis (68%) were caused by perforation of the gastrointestinal tract. Post-operative persistent sepsis occurred in 28 patients. The discriminative capacity of the decision tool score was fair (area under the curve of the receiver operating characteristic = 0.79). The incidence rate differed significantly between the three score categories (p peritonitis, the decision tool score predicts with fair accuracy whether persistent sepsis is present.

Recent advances in imaging the fetus in uterine have brought about the knowledge of prenatal process of the meconium peritonitis (mp), a chemical peritonitis by intestinal perforation, which was unknown hitherto. This paper describes the retrospective examination of perinatal diagnosis, treatment and management of mp essentially based on authors' experiences. Subjects are 18 fetuses (6.9%) with mp or suspicious mp/260 with possible diseases necessary for surgery during the period Mar. 2002-Dec. 2007. All subjects received ultrasonography (US) and MR imaging and were diagnosed as mp in 12 cases (66.7%). Seven cases were found to be in the fibroadhesive type (FA), 4 in cystic type (C) and 1 in generalized type (G), and neonates with the second and third types tended to be resulted in premature birth. The causes were found by laparotomy to be due to intestinal atresia (10 cases, 83.3%), atresia complicated with aproctia (1) and midgut axial volvulus (1). FA underwent intestinal anastomosis, and C and G, peritoneal drainage followed by anastomosis. For more appropriate perinatal management and possible prenatal surgery, needed is further elucidation of clinical features and pathophysiology of the disease. (R.T.)

♦ BACKGROUND: Peritonitis is one of the most common complications of peritoneal dialysis (PD). Understanding the risk factors of peritonitis in a multi-racial Asian population may help to improve outcomes on PD. ♦ METHODS: We conducted a prospective observational study to identify risk factors for PD-related peritonitis over a 1-year period in 15 adult PD centers. All peritonitis episodes were independently adjudicated. ♦ RESULTS: A total of 1,603 participants with a mean age of 51.6 years comprising 52.7% females, 62.6% ethnic Malays, 27.0% Chinese, and 8.1% Indians were recruited. The overall peritonitis rate was 1 episode per 44.0 patient-months with 354 episodes recorded in 282 (17.6%) patients over 15,588 patient-months. Significant risk factors of peritonitis were severe obesity (incidence-rate ratio [IRR] 3.32, 95% confidence interval [CI]: 1.30, 8.45), hypoalbuminemia (IRR 1.61, 95% CI: 1.06, 2.46), Staphylococcus aureus nasal carriage (IRR 2.26, 95% CI: 1.46, 3.50), and use of Fresenius system (Fresenius Medical Care North America, Waltham, MA, USA) (IRR 2.49, 95% CI: 1.27, 4.89). The risk of peritonitis was lower in those on automated PD compared with standard PD (IRR 0.43, 95% CI: 0.25, 0.74), and in centers with a patient-staff ratio of 15 to 29.9 (IRR 0.67, 95% CI: 0.49, 0.90) and ≥ 30 (IRR 0.52, 95% CI: 0.34, 0.80). Prevalent patients and exit-site care with topical antibiotics were also protective against peritonitis. Peritonitis rates varied between racial groups. The IRRs of overall peritonitis and gram-positive peritonitis in Chinese versus other racial groups were 0.65 (95% CI: 0.46, 0.90) and 0.47 (95% CI: 0.24, 0.91), respectively. ♦ CONCLUSIONS: Multiple patient, center, and PD-system factors influence the risk of peritonitis. In the Asian population, there are racial differences in the risk of peritonitis. Copyright © 2017 International Society for Peritoneal Dialysis.

Peritoneal dialysis in the neonatal intensive care unit. Management of acute renal failure after a severe subgaleal hemorrhage.

Acute renal failure is common in the neonatal intensive care unit but is often not recognized in its early phases, when it is potentially reversible. The typical patient with acute renal failure is premature, but many term infants are also at risk. One such group is those with severe bleeding, such as a subgaleal hemorrhage. In these cases, hypovolemia can quickly progress to ischemia, which affects many organs but has profound effects on the kidney. In term infants, acute renal failure is most commonly diagnosed in those with perinatal depression. This article presents a unique case of an infant with subgaleal and intracranial bleeding that resulted in acute renal failure requiring peritoneal dialysis in the hopes of the eventual restoration of kidney function.

Preclinical assessment of adjunctive tPA and DNase for peritoneal dialysis associated peritonitis.

Directory of Open Access Journals (Sweden)

Amanda L McGuire

Full Text Available A major complication of peritoneal dialysis is the development of peritonitis, which is associated with reduced technique and patient survival. The inflammatory response elicited by infection results in a fibrin and debris-rich environment within the peritoneal cavity, which may reduce the effectiveness of antimicrobial agents and predispose to recurrence or relapse of infection. Strategies to enhance responses to antimicrobial agents therefore have the potential to improve patient outcomes. This study presents pre-clinical data describing the compatibility of tPA and DNase in combination with antimicrobial agents used for the treatment of PD peritonitis. tPA and DNase were stable in standard dialysate solution and in the presence of antimicrobial agents, and were safe when given intraperitoneally in a mouse model with no evidence of local or systemic toxicity. Adjunctive tPA and DNase may have a role in the management of patients presenting with PD peritonitis.

Eosinophilic peritonitis: An unusual manifestation of tuberculous peritonitis in peritoneal dialysis patient

Full Text Available Eosinophilic peritonitis is an uncommon clinical entity with diagnostic considerations separate from those of tuberculous peritonitis. We report a patient on continuous ambulatory peritoneal dialysis (CAPD with eosinophilic peritonitis resulting from tuberculous peritonitis. Acid-fast stain and mycobacterial culture of peritoneal dialysis effluent were both negative result. In the peritoneal dialysis effluent and blood samples, Mycobacterium tuberculosis was detected by polymerase chain reaction analyses. The initiation of antituberculous therapy resulted in resolution of the eosionphilia in the dialysis effluent. After 14 days of antituberculous therapy, the polymerase chain reaction analyses of tuberculosis were negative for both the blood and peritoneal dialysis effluents. Evaluation of tuberculosis infection is necessary if the CAPD-related peritonitis presents with an unusual and unexplained clinical course. Polymerase chain reaction can play an important role in the diagnosis of tuberculous peritonitis in patients undergoing CAPD.

To determine the cost of the dialytic management of paediatric acute kidney injury in a low-income country. All children under the age of 15 years, who had either peritoneal dialysis or haemodialysis for acute kidney injury in Aminu Kano Teaching Hospital over a 1-year period, were studied. The average cost of each dialysis modality was estimated. Of 20 children, who had dialysis for acute kidney injury, 12 (60%) had haemodialysis and 8 (40%) had peritoneal dialysis. The mean cost for haemodialysis exceeded that of peritoneal dialysis ($363.33 vs. $311.66, t = 1.04, P = 0.313) with the mean cost of consumables significantly accounting for most of the cost variation ($248.49 vs. $164.73, t = 2.91, P = 0.009). Mean costs of nephrologist visit and nursing were not found to be significant. Peritoneal dialysis is the less costly alternative for managing acute kidney injury in children in our environment. © 2014 John Wiley & Sons Ltd.

To create a reliable system for assessing of severity and prediction of the outcome of peritonitis. Critical analysis of the systems for peritonitis severity assessment is presented. The study included outcomes of 347 patients who admitted at the Department of Faculty Surgery of Peoples' Friendship University of Russia in 2015-2016. The cause of peritonitis were destructive forms of acute appendicitis, cholecystitis, perforated gastroduodenal ulcer, various perforation of small and large intestines (including tumor). Combined forecasting system for peritonitis severity assessment is created. The system includes clinical, laboratory data, assessment of systemic inflammatory response (SIRS) and severity of organ failure (qSOFA). The authors focused on easily identifiable parameters which are available in virtually any surgical hospital. Threshold value (lethal outcome probability over 50%) is 8 scores in this system. Sensitivity, specificity and accuracy were 93.3, 99.7 and 98.9%, respectively according to ROC-curve that exceeds those parameters of MPI and APACHE II.

Alvarez, Eduardo; Castillo, Alvaro; Iturrieta, Isabel

Fungal peritonitis is a relatively uncommon infection in peritoneal dialysis patients. However, it can be associated with significant morbimortality. In recent reports, Candida species and other filamentous fungi have been reported as being aetiological agents. Thermoascus species are ubiquitous, thermophilic fungi, with an anamorph in the Paecilomyces genus. Here we present the first report of fungal peritonitis by Thermoascus crustaceus from Chile. We present the case of an 83-year-old female patient, with a history of cholecystectomy, hernia repair, severe arterial hypertension, hip and knee osteoarthritis and several episodes of peritoneal dialysis with a cloudy exudate. Bacterial cultures were negative. In addition, a history of two months with intermittent fever peaks mainly in the evening was reported. Blood culture bottles inoculated with peritoneal fluid revealed the presence of fungal growth. Morphological and molecular studies allowed us to identify the aetiological agent as Thermoascus crustaceus. An antifungal susceptibility test was performed using the M38-A2 method, developed by the Clinical and Laboratory Standards Institute (CLSI). The MIC values to amphotericin B, itraconazole, voriconazole and echinochandins were 0.5, 0.25, 0.25 and 0.125μg/ml, respectively. Antifungal treatment with amphotericin B was prescribed, with good patient progress. Fungal peritonitis is a very rare entity. Moreover, the spectrum of fungal pathogens continues to expand, a reason for which morphological and molecular studies are necessary for a rapid diagnosis.

The Mutual Relationship Between Peritonitis and Peritoneal Transport.

2016-01-01

♦ Preservation of the peritoneum is required for long-term peritoneal dialysis (PD). We investigated the effect of multiple peritonitis episodes on peritoneal transport. ♦ Prospectively collected data from 479 incident PD patients treated between 1990 and 2010 were analyzed, using strict inclusion criteria: follow-up of at least 3 years with the availability of a Standard Peritoneal Permeability Analysis (SPA) in the first year after start of PD and within the third year of PD, without peritonitis preceding the first SPA. For the purpose of the study, we only included patients who remained peritonitis-free (n = 28) or who experienced 3 or more peritonitis episodes (n = 16). ♦ At baseline the groups were similar with regard to small solute and fluid transport. However, the frequent peritonitis group had lower peritoneal protein clearances compared to the no peritonitis group, resulting in lower dialysate concentrations of proteins: albumin 196.5 mg/L vs 372.5 mg/L, IgG 36.4 mg/L vs 65.0 mg/L, and α-2-macroglobulin (A2M) 1.9 mg/L vs 3.6 mg/L, p peritonitis group. Frequent peritonitis did not affect free water transport. ♦ Slow initial peritoneal transport rates of serum proteins result in lower dialysate concentrations, and likely a lower opsonic activity, which is a risk factor for peritonitis. Patients with frequent peritonitis show an increase in small solute transport and a concomitant decrease of ultrafiltration. In long-term peritonitis-free PD patients, small solute transport decreased, while ultrafiltration increased. This suggests that frequent peritonitis leads to an increase of the vascular peritoneal surface area without all the structural membrane alterations that may develop after long-term PD.

♦ The quality of the peritoneal membrane can deteriorate over time. Exposure to glucose-based dialysis solutions is the most likely culprit. Because peritonitis is a common complication of peritoneal dialysis (PD), distinguishing between the effect of glucose exposure and a possible additive effect of peritonitis is difficult. The aim of the present study was to compare the time-course of peritoneal transport characteristics in patients without a single episode of peritonitis-representing the natural course-and in patients who experienced 1 or more episodes of peritonitis during long-term follow-up. ♦ This prospective, single-center cohort study enrolled incident adult PD patients who started PD during 1990-2010. A standard peritoneal permeability analysis was performed in the first year of PD treatment and was repeated every year. The results in patients without a single episode of peritonitis ("no-peritonitis group") were compared with the results obtained in patients who experienced 1 or more peritonitis episodes ("peritonitis group") during a follow-up of 4 years. ♦ The 124 patients analyzed included 54 in the no-peritonitis group and 70 in the peritonitis group. The time-course of small-solute transport was different in the groups, with the peritonitis group showing an earlier and more pronounced increase in the mass transfer area coefficient for creatinine (p = 0.07) and in glucose absorption (p = 0.048). In the no-peritonitis group, the net ultrafiltration rate (NUFR) and the transcapillary ultrafiltration rate (TCUFR) both showed a steep increase from the 1st to the 2nd year of PD that was absent in the peritonitis group. Both groups showed a decrease in the NUFR after year 3. A decrease in the TCUFR occurred only in the peritonitis group. That decrease was already present after the year 1 in patients with severe peritonitis. The time-course of free water transport showed a continuous increase in the patients without peritonitis, but a decrease in the

Nocardia asteroides is a rare pathogen in peritoneal dialysis-related peritonitis. We report on a 13-year-old female with Nocardia asteroides peritonitis complicated by an intra-abdominal abscess. Linezolid was administered intravenously for 3 months and followed by oral therapy for an additional 5 months with close monitoring for adverse effects. The patient was discharged after 3 months of hospitalization on hemodialysis. The diagnosis and management of such cases can be problematic due to the slow growth and difficulty of identifying Nocardia species. The optimal duration of treatment for Nocardia peritonitis is not known. Linezolid can be used for prolonged periods in cases of trimethoprim/sulfamethoxazole-resistant cases with close monitoring for adverse effects.

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv.

Peritonitis on catheter of dialysis represents the most frequent complication of the peritoneal dialysis (PD) in the pediatric population. It remains a significant cause of morbidity and mortality. In this study, we investigated the risk factors for peritonitis in children. In this study, we retrospectively collected the records of 85 patients who were treated with PD within the past ten years in the service of pediatrics of the University Hospital Charles-Nicolle of Tunis. Peritonitis rate was 0.75 episode per patient-year. Notably, peritonitis caused by Gram-positive organisms were more common. Analysis of infection risk revealed three significant independent factors: the poor weight (P=0.0045), the non-automated PD (P=0.02) and the short delay from catheter insertion to starting PD (P=0.02). The early onset peritonitis was significantly associated with frequent peritonitis episodes (P=0.0008). The mean duration between the first and second episode of peritonitis was significantly shorter than between PD commencement and the first episode of peritonitis. We revealed a significant association between Gram-negative peritonitis and the presence of ureterostomy (0.018) and between Gram-positive peritonitis and the presence of exit-site and tunnel infections (0.02). Transition to permanent hemodialysis was needed in many children but no death occurred in patients with peritonitis. Considering the important incidence of peritonitis in our patients, it is imperative to establish a targeted primary prevention. Nutritional care must be provided to children to avoid poor weight. The automated dialysis has to be the modality of choice. Copyright © 2015 Association Société de néphrologie. Published by Elsevier SAS. All rights reserved.

Full Text Available Abstract Background Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. Methods From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years underwent emergent and/or urgent surgery. Among them, 602 (64.3% were operated on laparoscopically (of whom 112 -18.7% – with peritonitis, according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. Results The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat. of cases, and 90.6% (87 of these patients were treated successfully by Laparoscopy. Conclusion Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal

To develop an alcoholic extract of the inner bark of the Schinus terebinthifolius raddi and to test its impact on autogenously fecal peritonitis in Wistar rats. The inner bark of the Schinus terebinthifolius raddi was kept for seven days in 70% ethanol alcohol. The total elimination of the solvent was performed in a rotary evaporator under reduced pressure at 55-60°C. Four milliliter of this extract was injected, after 24 h, into the abdominal cavity of six out of eight survival rats that underwent autogenously fecal peritonitis with five milliliter of 10% filtered fecal suspension. They were clinically followed up for 45 days when they were euthanized. The necropsy findings (inventory) of the abdominal and thorax cavities were inspected and the main findings were recorded and photographed. The investigation was approved by the Ethics Committee. Two out of six survival rats that were critically ill after 24 h died within the 12 h after the extract injection into the abdominal cavity. Four rats that were also critically ill recovered and gradually became healthy, eating well, regaining weight and moving normally in the cage. At 45 days post severe peritonitis the necropsy findings revealed few signs of residual infection on the abdominal and thorax cavities. There were no bowel adhesions. The impact of alcoholic extract of the inner bark of the Schinus terebinthifolius raddi was considered very positive and promising as natural local antiseptic against very severe peritonitis in Wistar rats.

♦ Objective: Little or no evidence is available on the impact of the first peritonitis episode on peritoneal transport characteristics. The objective of this study was to investigate the importance of the very first peritonitis episode and distinguish its effect from the natural course by comparison of peritoneal transport before and after infection. ♦ Participants: We analyzed prospectively collected data from 541 incident peritoneal dialysis (PD) patients, aged > 18 years, between 1990 and 2010. Standard Peritoneal Permeability Analyses (SPA) within the year before and within the year after (but not within 30 days) the first peritonitis were compared. In a control group without peritonitis, SPAs within the first and second year of PD were compared. ♦ Main outcome measurements: SPA data included the mass transfer area coefficient of creatinine, glucose absorption and peritoneal clearances of β-2-microglobulin (b2m), albumin, IgG and α-2-macroglobulin (a2m). From these clearances, the restriction coefficient to macromolecules (RC) was calculated. Also, parameters of fluid transport were determined: transcapillary ultrafiltration rate (TCUFR), lymphatic absorption (ELAR), and free water transport. Crude and adjusted linear mixed models were used to compare the slopes of peritoneal transport parameters in the peritonitis group to the control group. Adjustments were made for age, sex and diabetes. ♦ Results: Of 541 patients, 367 experienced a first peritonitis episode within a median time of 12 months after the start of PD. Of these, 92 peritonitis episodes were preceded and followed by a SPA within one year. Forty-five patients without peritonitis were included in the control group. Logistic reasons (peritonitis group: 48% vs control group: 83%) and switch to hemodialysis (peritonitis group: 22% vs control group: 3%) were the main causes of missing SPA data post-peritonitis and post-control. When comparing the slopes of peritoneal transport parameters in

Background and objectives There is conflicting evidence comparing peritonitis rates among patients treated with continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysis (APD). This study aims to clarify the relationship between peritoneal dialysis (PD) modality (APD versus CAPD) and the risk of developing PD-associated peritonitis. Design, setting, participants, & measurements This study examined the association between PD modality (APD versus CAPD) and the risks, microbiology, and clinical outcomes of PD-associated peritonitis in 6959 incident Australian PD patients between October 1, 2003, and December 31, 2011, using data from the Australia and New Zealand Dialysis and Transplant Registry. Median follow-up time was 1.9 years. Results Patients receiving APD were younger (60 versus 64 years) and had fewer comorbidities. There was no association between PD modality and time to first peritonitis episode (adjusted hazard ratio [HR] for APD versus CAPD, 0.98; 95% confidence interval [95% CI], 0.91 to 1.07; P=0.71). However, there was a lower hazard of developing Gram-positive peritonitis with APD than CAPD, which reached borderline significance (HR, 0.90; 95% CI, 0.80 to 1.00; P=0.05). No statistically significant difference was found in the risk of hospitalizations (odds ratio, 1.12; 95% CI, 0.93 to 1.35; P=0.22), but there was a nonsignificant higher likelihood of 30-day mortality (odds ratio, 1.33; 95% CI, 0.93 to 1.88; P=0.11) at the time of the first episode of peritonitis for patients receiving APD. For all peritonitis episodes (including subsequent episodes of peritonitis), APD was associated with lower rates of culture-negative peritonitis (incidence rate ratio [IRR], 0.81; 95% CI, 0.69 to 0.94; P=0.002) and higher rates of gram-negative peritonitis (IRR, 1.28; 95% CI, 1.13 to 1.46; P=0.01). Conclusions PD modality was not associated with a higher likelihood of developing peritonitis. However, APD was associated with a borderline

♦ BACKGROUND: Information related to the microbiology of peritonitis is critical to the optimal management of patients receiving peritoneal dialysis (PD). The goal was to characterize the microbiological etiology and antimicrobial susceptibilities of PD-related peritonitis (PDRP) from 2005 to 2014, inclusive. ♦ METHODS: The distribution of organisms in culture-positive PDRP was described for new episodes and relapse infections, and further detailed for monomicrobial and polymicrobial peritonitis. Annual and overall rates of PDRP were also characterized. Antimicrobial susceptibility rates were calculated for the most common and significant organisms. ♦ RESULTS: We identified 539 episodes of PDRP including 501 new and 38 relapse infections. New episodes of peritonitis were associated with a single organism in 85% of cases, and 44% of those involved staphylococci. Polymicrobial PDRP was more likely to involve gram-negative organisms, observed in 58% versus 24% of monomicrobial infections. Antimicrobial resistance was relatively stable from 2005 to 2014. Methicillin resistance was present in 57% of Staphylococcus epidermidis and 20% of other coagulase-negative staphylococci. Methicillin-resistant Staphylococcus aureus (MRSA) accounted for only 11% of S. aureus peritonitis compared with 2% in our previous study of PDRP from 1991 to 1998. Ciprofloxacin resistance in Escherichia coli increased from 3% in our previous study to 24% in 2005 - 2014. ♦ CONCLUSIONS: This study characterizes important differences in the distribution of organisms in new episodes of PDRP and relapse infections, as well as monomicrobial versus polymicrobial peritonitis. It also shows relatively stable rates of antimicrobial resistance from 2005 to 2014, but some increases compared with our previous study.

Maseda, Emilio; Gimenez, Maria-Jose; Gilsanz, Fernando; Aguilar, Lorenzo

2016-01-01

Adequate management of severely ill patients with secondary peritonitis requires supportive therapy of organ dysfunction, source control of infection and antimicrobial therapy. Since secondary peritonitis is polymicrobial, appropriate empiric therapy requires combination therapy in order to achieve the needed coverage for both common and more unusual organisms. This article reviews etiological agents, resistance mechanisms and their prevalence, how and when to cover them and guidelines for treatment in the literature. Local surveillances are the basis for the selection of compounds in antibiotic regimens, which should be further adapted to the increasing number of patients with risk factors for resistance (clinical setting, comorbidities, previous antibiotic treatments, previous colonization, severity…). Inadequate antimicrobial regimens are strongly associated with unfavorable outcomes. Awareness of resistance epidemiology and of clinical consequences of inadequate therapy against resistant bacteria is crucial for clinicians treating secondary peritonitis, with delicate balance between optimization of empirical therapy (improving outcomes) and antimicrobial overuse (increasing resistance emergence).

Percutaneous retrograde gastrostomy has a high success rate, low morbidity, and can be performed under different levels of sedation or local anesthesia in children. Despite its favourable safety profile, major complications can occur. Few studies have examined peritonitis following percutaneous retrograde gastrostomy in children. To identify potential risk factors and variables influencing the development and early diagnosis of peritonitis following percutaneous retrograde gastrostomy. We conducted a retrospective case-control study of children who developed peritonitis within 7 days of percutaneous retrograde gastrostomy between 2003 and 2012. From the 1,504 patients who underwent percutaneous retrograde gastrostomy, patients who developed peritonitis (group 1) were matched by closest date of procedure to those without peritonitis (group 2). Peritonitis was defined according to recognized clinical criteria. Demographic, clinical, procedural, management and outcomes data were collected. Thirty-eight of 1,504 children (2.5%; 95% confidence interval, 1.8-3.5) who underwent percutaneous retrograde gastrostomy developed peritonitis ≤7 days post procedure (group 1). Fever (89%), irritability (63%) and abdominal pain (55%) occurred on presentation of peritonitis. Group 1 patients were all treated with antibiotics; 41% underwent additional interventions: tube readjustments (8%), aspiration of pneumoperitoneum (23%), laparotomy (10%) and intensive care unit admission (10%). In group 1, enteral feeds started on average 3 days later and patients were discharged 5 days later than patients in group 2. There were two deaths not directly related to peritonitis. Neither age, gender, weight, underlying diagnoses nor operator was identified as a risk factor. Peritonitis following percutaneous retrograde gastrostomy in children occurs in approximately 2.5% of cases. No risk factors for its development were identified. Medical management is usually sufficient for a good outcome

Assessment of peritoneal permeability is necessary for successful management of end-stage renal disease (ESRD) patients by continuous ambulatory peritoneal dialysis (CAPD). The objective of this study was to develop an alternative method of assessing the peritoneal permeability and to compare this method with the conventional method, the peritoneal equilibrium test, first described by Twardowski in 1987. Twenty patients undergoing regular CAPD were included in this study. Before starting the peritoneal dialysis, 370 MBq (10 mCi) technetium-99m diethylene triamine penta-acetic acid ( 99m Tc-DTPA) was injected intravenously. A standard dose of the same quantity was kept and used later for calculations. At the end of 4 h, a dialysate fluid sample (1 ml) was collected and the total dialysis effluent fluid volume was measured. Excretion of 99m Tc-DTPA into the dialysate fluid as a percentage of the injected dose was calculated. Simultaneously, standard peritoneal equilibrium test values were recorded for comparison. Peritoneal excretion of 99m Tc-DTPA ranged from 8% to 25% of the injected dose, depending on the peritoneal membrane permeability. When the results were compared with the conventional method, a good correlation (r=0.79) was found. This innovative radionuclide technique is a simple and convenient method to assess the peritoneal membrane permeability and can be used as an alternative to the peritoneal equilibrium test, which is very cumbersome and associated with many limitations.

♦ Little or no clinical evidence is available on the association between glucose exposure and peritoneal host defense in peritoneal dialysis (PD) patients. The objective of the present study was to quantify the exposure to glucose during the first year on PD and investigate the association with subsequent peritonitis. ♦ We analyzed prospectively collected demographic and peritonitis data from incident adult PD patients between 1990 and 2010. For the present study, we conducted a review of both in- and outpatient medical records of all patients to obtain their day-to-day dialysis schemes during the first year on PD. From these data, the average exposure to glucose was quantified. The exposure was stratified into low- and high-glucose groups based on the median, analyzed per standard deviation and in quartiles. Cox proportional hazard models were used to calculate crude and adjusted hazard ratios (HRs) and 95% confidence intervals for the association between glucose exposure and peritonitis. Adjustments were made for age, sex, primary kidney disease, diabetes mellitus, Davies comorbidity score and the treatment period. ♦ In total, 230 patients were included in the study of whom 151 (66%) experienced a first peritonitis episode. The median follow-up time was 2.6 years (interquartile range [IQR]: 1.9 - 3.8) in the low-glucose group and 3.1 (IQR: 2.1 - 4.2) in the high-glucose group. After adjustment for confounding factors, no association between high glucose exposure and the risk of peritonitis was found (HR: 0.81; 0.55 - 1.17). No association was present when glucose exposure was analyzed per standard deviation (SD) (HR: 0.98; 0.79 - 1.21) or patient quartiles were applied. No association was identified between glucose exposure and severe peritonitis, Staphylococcus aureus peritonitis, or a peritonitis episode that lasted more than 14 days. ♦ Exposure to glucose is not associated with an increased risk of peritonitis.

Few studies have investigated the management of human immunodeficiency virus (HIV)-associated end-stage renal failure particularly in low-resource settings with limited access to renal replacement therapy. We aimed to evaluate the effects of HIV infection on continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis outcomes and technique failure in highly active antiretroviral therapy (HAART)-treated HIV-positive CAPD populations. We conducted a single-center prospective cohort study of consecutive incident CAPD patients recruited from two hospitals in Durban, South Africa from September 2012-February 2015. Seventy HIV-negative and 70 HIV-positive end-stage renal failure patients were followed monthly for 18 months at a central renal clinic. Primary outcomes of peritonitis and catheter failure were assessed for the first 18 months of CAPD therapy. We assessed risk factors for peritonitis and catheter failure using Cox regression survival analysis. The HIV-positive cohort had a significantly increased rate of peritonitis compared to the HIV-negative cohort (1.86 vs. 0.76 episodes/person-years, respectively; hazard ratio [HR], 2.41; 95% confidence interval [CI], 1.69-3.45, P peritonitis rate rose to 3.69 episodes/person-years (HR 4.54, 95% CI 2.35-8.76, P peritonitis rate of 1.60 episodes/person-years (HR 2.10, CI 1.39-3.15, P = 0.001). HIV was associated with increased hazards of peritonitis relapse (HR, 3.88; CI, 1.37-10.94; P = 0.010). Independent predictors associated with increased peritonitis risk were HIV (HR, 1.84; CI, 1.07-3.16; P = 0.027), diabetes (HR, 2.09; CI, 1.09-4.03; P = 0.027) and a baseline CD4 count Peritonitis (HR, 14.47; CI, 2.79-75.00; P = 0.001), average hemoglobin concentrations (HR, 0.75; CI, 0.59-0.95; P = 0.016), and average serum C-reactive protein levels were independent predictors of catheter failure.

Barium sulfate is universally used contrast media in gastrointestinal roentgenology, and spillage of barium into peritoneal cavity can occur. The references on effect of barium sulfate in the peritoneal cavity have been scattered and the results are varied. In 80 rats, body weight of 130 gm to 150 gm, sterile pure barium, sterile commercial barium, intestinal content, and mixed pure barium and intestinal content were experimentally injected into the peritoneal cavity. Consecutive weekly laparotomy and microscopic examination were done for 4 weeks. The results are as followings: 1. Mind inflammatory reaction and mild adhesion after sterile pure barium injection. 2. Mild inflammatory reaction and moderate adhesion after sterile commercial barium injection. 3. Acute peritonitis and abscess formation after intestinal content injection. 4. High mortality due to severe acute peritonitis, and severe adhesion in survivors after injection of both pure barium and intestinal content.

♦ Background: A multicenter, multi-country randomized controlled trial (the balANZ study) recently reported that peritonitis rates significantly improved with the use of neutral-pH peritoneal dialysis (PD) solutions low in glucose degradation products (“biocompatible”) compared with standard solutions. The present paper reports a secondary outcome analysis of the balANZ trial with respect to peritonitis microbiology, treatment, and outcomes. ♦ Methods: Adult incident PD patients with residual renal function were randomized to receive either biocompatible or conventional (control) PD solutions for 2 years. ♦ Results: The safety population analysis for peritonitis included 91 patients in each group. The unadjusted geometric mean peritonitis rates in those groups were 0.30 [95% confidence interval (CI): 0.22 to 0.41] episodes per patient-year for the biocompatible group and 0.49 (95% CI: 0.39 to 0.62) episodes per patient-year for the control group [incidence rate ratio (IRR): 0.61; 95% CI: 0.41 to 0.90; p = 0.01]. When specific causative organisms were examined, the rates of culture-negative, gram-positive, gram-negative, and polymicrobial peritonitis episodes were not significantly different between the biocompatible and control groups, although the biocompatible group did experience a significantly lower rate of non-pseudomonal gram-negative peritonitis (IRR: 0.41; 95% CI: 0.18 to 0.92; p = 0.03). Initial empiric antibiotic regimens were comparable between the groups. Biocompatible fluid use did not significantly reduce the risk of peritonitis-associated hospitalization (adjusted odds ratio: 0.80; 95% CI: 0.48 to 1.34), but did result in a shorter median duration of peritonitis-associated hospitalization (6 days vs 11 days, p = 0.05). Peritonitis severity was more likely to be rated as mild in the biocompatible group (37% vs 10%, p = 0.001). Overall peritonitis-associated technique failures and peritonitis-related deaths were comparable in the two groups

Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange. A single-center, retrospective, case-control study was undertaken to determine whether this operating vehicle has a protective role in preventing peritonitis. In total, 462 continuous ambulatory peritoneal dialysis patients were included in this study from October 2014 to March 2017. According to their personal will, these patients chose to use operating vehicle or traditional method during their bag exchange. The demographic, clinical and laboratory data of these patients in the two groups were collected, analyzed and compared. Of 462 patients with home dialysis, operating vehicle group consisted of 61 patients, and control group consisted of 401 patients. In the control group, over 677 patient-years, peritonitis occurred in 69 of 401 patients (17.2%), while in the operating vehicle group, over 60 patient-years, only 4 of 61 patients (6.6%) had episodes of peritonitis. The number of patients suffered from peritonitis was significantly decreased in the operating vehicle group (P = 0.034). Besides, there were a total of 99 episodes of peritonitis, and the rate was 1 episode every 7.2 patient-years in control group and 1 episode every 12 patient-years in the operating vehicle group. There was significant difference between the two groups (0.013). Positive dialysate cultures were obtained in majority of the peritonitis episodes (60.6%). Operating vehicle might help to reduce PD-related peritonitis by preventing contamination during bag

We report a rare case of barium peritonitis following an upper gastrointestinal (GI) series and its imaging findings in a 74-year-old female. Barium peritonitis is a rare but life-threatening complication of GI contrast investigation. Therefore, clinical awareness of barium peritonitis as a complication of GI tract contrast investigation would help to prevent such a complication and manage the patients properly.

♦ Objectives: We compared the clinical characteristics and outcomes of “silent” peritonitis (meaning episodes without fever and abdominal pain) and “non-silent” peritonitis in patients on peritoneal dialysis (PD). ♦ Methods: Our cohort study collected data about all peritonitis episodes occurring between January 2008 and April 2010. Disease severity score, demographics, and biochemistry and nutrition data were recorded at baseline. Effluent cell counts were examined at regular intervals, and the organisms cultured were examined. Treatment failure was defined as peritonitis-associated death or transfer to hemodialysis. ♦ Results: Of 248 episodes of peritonitis occurring in 161 PD patients, 20.9% led to treatment failure. Of the 248 episodes, 51 (20.6%) were not accompanied by fever and abdominal pain. Patients with these silent peritonitis episodes tended to be older (p = 0.003). The baseline values for body mass index, triglycerides, and daily energy intake were significantly lower before silent peritonitis episodes than before non-silent episodes (p = 0.01, 0.003, and 0.001 respectively). Although silent peritonitis episodes were more often culture-negative and less often caused by gram-negative organisms, and although they presented with low effluent white cell counts on days 1 and 3, the risk for treatment failure in those episodes was not lower (adjusted odds ratio: 1.33; 95% confidence interval: 0.75 to 2.36; p = 0.33). ♦ Conclusions: Silent peritonitis is not a rare phenomenon, especially in older patients on PD. Although these episodes were more often culture-negative, silent presentation was not associated with a better outcome. PMID:22855888

♦ Background: The clinical courses and long-term outcomes of viridans streptococcus (VS) peritoneal dialysis (PD) peritonitis remain unclear. ♦ Methods: We conducted a retrospective analysis of all PD patients in a single center with gram-positive cocci (GPC) peritonitis between 2005 and 2011, and divided them into 3 groups: VS, other streptococci and other GPC (apart from VS). Clinical characteristics and outcomes of the VS group were compared with the other streptococci and other GPC groups, with prognostic factors determined. ♦ Results: A total of 140 patients with 168 episodes of GPC peritonitis (44% of all peritonitis) were identified over 7 years. Among these, 18 patients (13%) developed VS peritonitis, while 14 patients (10%) developed other streptococcal peritonitis. Patients with VS peritonitis had a high cure rate by antibiotic alone (94%), despite a high polymicrobial yield frequency (28%). We found that VS peritonitis carried a lower risk of Tenckhoff catheter removal and relapsing episodes than other GPC peritonitis (6% vs 11%), and a lower mortality than other streptococci peritonitis (0% vs 7%). However, after the index peritonitis episodes, VS, other streptococci, and other GPC group had a significantly increased peritonitis incidence compared with the period before the index peritonitis (all p peritonitis had a significantly higher incidence of refractory peritonitis compared with other streptococci or other GPC peritonitis in the long term (both p peritonitis after the index episode as compared with other streptococcal or GPC peritonitis. It might be prudent to monitor the technique of these patients with VS peritonitis closely to avoid further peritonitis episodes. PMID:24497584

♦ Background: Peritoneal dialysis (PD)–associated peritonitis clusters within patients. Patient factors contribute to peritonitis risk, but there is also entrapment of organisms within the biofilm that forms on PD catheters. It is hypothesized that this biofilm may prevent complete eradication of organisms, predisposing to multiple infections with the same organism. ♦ Methods: Using data collected in the Canadian multicenter Baxter POET (Peritonitis, Organism, Exit sites, Tunnel infections) database from 1996 to 2005, we studied incident PD patients with 2 or more peritonitis episodes. We determined the proportion of patients with 2 or more episodes caused by the same organism. In addition, using a multivariate logistic regression model, we tested whether prior peritonitis with a given organism predicted the occurrence of a subsequent episode with the same organism. ♦ Results: During their time on PD, 558 patients experienced 2 or more peritonitis episodes. Of those 558 patients, 181 (32%) had at least 2 episodes with the same organism. The organism most commonly causing repeat infection was coagulase-negative Staphylococcus (CNS), accounting for 65.7% of cases. Compared with peritonitis caused by other organisms, a first CNS peritonitis episode was associated with an increased risk of subsequent CNS peritonitis within 1 year (odds ratio: 2.1; 95% confidence interval: 1.5 to 2.8; p peritonitis, 48% of repeat episodes occurred within 6 months of the earlier episode. ♦ Conclusions: In contrast to previous data, we did not find a high proportion of patients with multiple peritonitis episodes caused by the same organism. Coagulase-negative Staphylococcus was the organism most likely to cause peritonitis more than once in a given patient, and a prior CNS peritonitis was associated with an increased risk of CNS peritonitis within the subsequent year.

Full Text Available Although generally rising in incidence, intestinal tuberculosis is still rare in western countries and due to unspecific manifestations mainly as ulcerations on endoscopy, diagnosis of intestinal tuberculosis is challenging. Within this report, we describe a case of severe intestinal tuberculosis radiologically and endoscopically masquerading as colorectal cancer with peritoneal carcinomatosis. Our case exemplifies that intestinal tuberculosis needs to be considered as a differential diagnosis in patients at risk and that undelayed and sensitive diagnosis of intestinal tuberculosis is of central importance for avoiding unfavorable disease outcome.

Maintenance peritoneal dialysis (PD) is the dialysis modality of choice for infants and young children. However, there are limited outcome data for those who undergo PD catheter insertion and initiate maintenance PD within the first year of life. Using data from the Children's Hospital Association's Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (ESRD) Collaborative (SCOPE), we examined peritonitis rates and patient survival in 156 infants from 29 North American pediatric dialysis centers who had a chronic PD catheter placed prior to their first birthday. In-hospital and overall annualized rates of peritonitis were 1.73 and 0.76 episodes per patient-year, respectively. Polycystic kidney disease was the most frequent renal diagnosis and pulmonary hypoplasia the most common co-morbidity in infants with peritonitis. Multivariable regression models demonstrated that nephrectomy at or prior to PD catheter placement and G-tube insertion after catheter placement were associated with a nearly sixfold and nearly threefold increased risk of peritonitis, respectively. Infants with peritonitis had longer initial hospital stays and lower overall survival (86.3 vs. 95.6%, respectively; P high and several risk factors associated with the development of peritonitis were identified. Given that peritonitis was associated with a longer duration of initial hospitalization and increased mortality, increased attention to the potentially modifiable risk factors for infection is needed.

Full Text Available BACKGROUND: Peritonitis still presents an extremely common & dreaded problem in emergency surgery. Despite aggressive surgical techniques, the prognosis of peritonitis and intra - abdominal sepsis is very poor, especially when multiple organ failure develops. Therefore early objective & reliable classification of the severity of peritonitis and intra - abdominal sepsis is needed not only to predict prognosis & to select patients for these aggressive surgical techniques but also to evaluate & compare the results of different treatment regimens. So, in this prospective st udy of 60 cases of peritonitis, the reliability of the Mannheim peritonitis index is assessed & its predictive power evaluated. MATERIALS & METHOD S : This prospective study was carried out in the department of surgery, GMCH, Udaipur from June 2014 to June 2 015 after taking the permission from institutional ethics committee. Patients from both sexes of various age groups having peritonitis of varied aetiology & who had undergone laparotomy were taken. A detailed history, thorough clinical examination & necess ary investigations were performed in e ach case according to planned p r o forma. After resuscitation laparotomy was done & operative findings were noted carefully and a proper note on the progress of each patient was maintained and any complications encounter ed were noted. So, early classification of patients presenting with peritonitis by means of objective scoring system was done to select patients for aggressive surgery & overall morbidity & mortality were analyzed. RESULTS: Total 60 patients of peritonitis were examined and common causes were peptic (61.6%, typhoid (21.6% and appendicular (8.3 %. Most common age group was found to be 21 to 50 years and male to female ratio was 4:1. Peritonitis was more common in patients involved in hard work and chronic Be di smokers (61.6%.

Endometriosis causes significant chronic pelvic pain, dysmenorrhea, and infertility and affects 10% of all women. In endometriosis, ectopic endometrium surviving after retrograde menstruation exhibits an abnormal immune response characterized by increased levels of activated macrophages and inflammatory cytokines. Particularly, dysfunctional natural killer (NK) cells play an important role in the pathogenesis of the disease by either facilitating or inhibiting the survival, implantation, and proliferation of endometrial cells. NK cells in the peritoneum and peritoneal fluid exhibit reduced levels of cytotoxicity in women with endometriosis. Several cytokines and inhibitory factors in the serum and peritoneal fluid also dysregulate NK cell cytotoxicity. Additionally, increased numbers of immature peripheral NK cells and induction of NK cell apoptosis are evident in the peritoneal fluid of women with endometriosis. The high rate of endometriosis recurrence after pharmaceutical or surgical treatment, which is associated with dysfunctional NK cells, indicates that new immunomodulatory management strategies are required. A good understanding of immune dysfunction would enable improvement of current treatments for endometriosis.

Background Bacterial infections account for most peritoneal dialysis (PD)-associated peritonitis episodes. However, anaerobic PD peritonitis is extremely rare and intuitively associated with intra-abdominal lesions. In this study, we examined the clinical characteristics of PD patients who developed anaerobic peritonitis. Methods We retrospectively identified all anaerobic PD peritonitis episodes from a prospectively collected PD registry at a single center between 1990 and 2010. Only patient...

Peritoneal carcinomatosis represents a devastating form of cancer progression with a very poor prognosis. Its complex pathogenesis is represented by a dynamic process comprising several steps. To the best of our knowledge pathogenesis can be partly explained by 3 major molecular pathways: (1) dissemination from the primary tumor; (2) primary tumor of peritoneum; and (3) independent origins of the primary tumor and peritoneal implants. These are not mutually exclusive and combinations of different mechanisms could occur inside a single case. There are still several aspects which need explanation by future studies. A comprehensive understanding of molecular events involved in peritoneal carcinomatosis is of paramount importance and should be systematically pursued not only to identify novel strategies for the prevention of the condition, but also to obtain therapeutic advances, through the identification of surrogate markers of prognosis and development of future molecular targeted therapies.

AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis (PD) patients. METHODS: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis (peritonitis group, group A) to patients who never had peritonitis (no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric organisms. RESULTS: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode of peritonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients (39.3%) in group A and 15 of 59 patients (25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker (H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis (EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD patients. CONCLUSION: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

Full Text Available Sclerosing encapsulating peritonitis (SEP is a rare chronic inflammatory condition of the peritoneum with an unknown aetiology. Also known as abdominal cocoon, the condition occurs when loops of the bowel are encased within the peritoneal cavity by a membrane, leading to intestinal obstruction. Due to its rarity and nonspecific clinical features, it is often misdiagnosed. The condition presents with recurrent episodes of small bowel obstruction and can be idiopathic or secondary; the latter is associated with predisposing factors such as peritoneal dialysis or abdominal tuberculosis. In the early stages, patients can be managed conservatively; however, surgical intervention is necessary for those with advanced stage intestinal obstruction. A literature review revealed 118 cases of SEP; the mean age of these patients was 39 years and 68.0% were male. The predominant presentation was abdominal pain (72.0%, distension (44.9% or a mass (30.5%. Almost all of the patients underwent surgical excision (99.2% without postoperative complications (88.1%.

Residual renal function and the integrity of the peritoneal membrane contribute to morbidity and mortality among patients treated with peritoneal dialysis. Glucose and its degradation products likely contribute to the deterioration of the remnant kidney and damage to the peritoneum. Benfotiamine decreases glucose-induced tissue damage, suggesting the potential for benefit in peritoneal dialysis. Here, in a model of peritoneal dialysis in uremic rats, treatment with benfotiamine decreased peritoneal fibrosis, markers of inflammation, and neovascularization, resulting in improved characteristics of peritoneal transport. Furthermore, rats treated with benfotiamine exhibited lower expression of advanced glycation endproducts and their receptor in the peritoneum and the kidney, reduced glomerular and tubulointerstitial damage, and less albuminuria. Increased activity of transketolase in tissue and blood contributed to the protective effects of benfotiamine. In primary human peritoneal mesothelial cells, the addition of benfotiamine led to enhanced transketolase activity and decreased expression of advanced glycation endproducts and their receptor. Taken together, these data suggest that benfotiamine protects the peritoneal membrane and remnant kidney in a rat model of peritoneal dialysis and uremia.

♦ Background: Peritonitis rate has been reported to be associated with technique failure and overall mortality in previous literatures. However, information on the impact of the timing of the first peritonitis episode on continuous ambulatory peritoneal dialysis (CAPD) patients is sparse. The aim of this research is to study the influence of time to first peritonitis on clinical outcomes, including technique failure, patient mortality and dropout from peritoneal dialysis (PD). ♦ Methods: A retrospective observational cohort study was conducted over 10 years at a single PD unit in Taiwan. A total of 124 patients on CAPD with at least one peritonitis episode comprised the study subjects, which were dichotomized by the median of time to first peritonitis into either early peritonitis patients or late peritonitis patients. Cox proportional hazard model was used to analyze the correlation of the timing of first peritonitis with clinical outcomes. ♦ Results: Early peritonitis patients were older, more diabetic and had lower serum levels of creatinine than the late peritonitis patients. Early peritonitis patients were associated with worse technique survival, patient survival and stay on PD than late peritonitis patients, as indicated by Kaplan-Meier analysis (log-rank test, p = 0.04, p peritonitis was still a significant predictor for technique failure (hazard ratio (HR), 0.54; 95% confidence interval (CI), 0.30 - 0.98), patient mortality (HR, 0.34; 95% CI, 0.13 - 0.92) and dropout from PD (HR, 0.50; 95% CI, 0.30 - 0.82). In continuous analyses, a 1-month increase in the time to the first peritonitis episode was associated with a 2% decreased risk of technique failure (HR, 0.98; 95% CI, 0.97 - 0.99), a 3% decreased risk of patient mortality (HR, 0.97; 95% CI, 0.95 - 0.99), and a 2% decreased risk of dropout from PD (HR, 98%; 95% CI, 0.97 - 0.99). Peritonitis rate was inversely correlated with time to first peritonitis according to the Spearman analysis (r = -0

Peritonitis is a major complication of peritoneal dialysis, but the relationship between peritonitis and mortality among these patients is not well understood. In this case-crossover study, we included the 1316 patients who received peritoneal dialysis in Australia and New Zealand from May 2004 through December 2009 and either died on peritoneal dialysis or within 30 days of transfer to hemodialysis. Each patient served as his or her own control. The mean age was 70 years, and the mean time receiving peritoneal dialysis was 3 years. In total, there were 1446 reported episodes of peritonitis with 27% of patients having ≥2 episodes. Compared with the rest of the year, there were significantly increased odds of peritonitis during the 120 days before death, although the magnitude of this association was much greater during the 30 days before death. Compared with a 30-day window 6 months before death, the odds for peritonitis was six-fold higher during the 30 days immediately before death (odds ratio, 6.2; 95% confidence interval, 4.4–8.7). In conclusion, peritonitis significantly associates with mortality in peritoneal dialysis patients. The increased odds extend up to 120 days after an episode of peritonitis but the magnitude is greater during the initial 30 days. PMID:22626818

Peritoneal dialysis (PD) is frequently complicated by high rates of peritonitis, which result in hospitalization, technique failure, transfer to hemodialysis, and increased mortality. Early diagnosis, and identification of contributing factors are essential components to increasing effectiveness of care. In previous reports, neutrophil gelatinase-associated lipocalin (NGAL), a lipocalin which is a key player in innate immunity and rapidly detectable in peritoneal dialysis effluent (PDE), has been demonstrated to be a useful tool in the early diagnosis of peritonitis. This study investigates predictive value of PDE NGAL concentration as a prognostic indicator for PD-related peritonitis. A case-control study with 182 PD patients was conducted. Plasma and PDE were analyzed for the following biomarkers: C-reactive protein (CRP), blood procalcitonin (PCT), leucocytes and NGAL in PDE. The cases consisted of patients with suspected peritonitis, while controls were the patients who came to our ambulatory clinic for routine visits without any sign of peritonitis. The episodes of peritonitis were defined in agreement with International Society for Peritoneal Dialysis guidelines. Continuous variables were presented as the median values and interquartile range (IQR). Mann-Whitney U test was used to compare continuous variables. Univariate and multivariate logistic regression were used to evaluate the association of biomarkers with peritonitis. Receiver operating characteristic (ROC) curve analysis was used to calculate area under curve (AUC) for biomarkers. Finally we evaluated sensitivity, and specificity for each biomarker. All statistical analyses were performed with SPSS version 17.0 (SPSS Inc., Chicago, IL, USA). During the 19-month study, of the 182 patients, 80 had a clinical diagnosis of peritonitis.

Giri Smith

2012-02-01

Full Text Available Abstract Introduction Retroperitoneal necrotizing fasciitis is a rare, fulminant, and potentially lethal complication of intra-abdominal suppuration. A retroperitoneal origin is very rare and very few cases have been reported in the literature. To the best of our knowledge, this case is only the fourth case reported of successful management following retroperitoneal necrotizing fasciitis. Case presentation A 33-year-old Tamang man presented to our facility with a history of five days of fever and vomiting and eight days of severe left loin pain. On examination, he had features of peritonism. A laparotomy was performed, revealing extensive necrotizing fasciitis of the retroperitoneum extending to the anterior abdominal wall. Our patient survived following extensive debridement of the necrotic tissues and supportive care. Conclusions Retroperitoneal necrotizing fasciitis can rarely present with features of peritonism, and hence should be included as a possible differential diagnosis for anyone presenting with peritonism. Although a fatal condition, early intervention and aggressive management can save the life of a patient.

♦ Introduction: Escherichia coli (E. coli) peritonitis is a frequent, serious complication of peritoneal dialysis (PD). The extended-spectrum β-lactamase (ESBL)-producing E. coli peritonitis is associated with poorer prognosis and its incidence has been on continuous increase during the last decades. However, the clinical course and outcomes of E. coli peritonitis remain largely unclear. ♦ Methods: All of the E. coli peritonitis episodes that occurred in our dialysis unit from 2006 to 2011 were reviewed. The polymicrobial episodes were excluded. ♦ Results: In total, ninety episodes of monomicrobial E. coli peritonitis occurred in 68 individuals, corresponding to a rate of 0.027 episodes per patient-year. E. coli was the leading cause (59.2%) of monomicrobial gram-negative peritonitis. ESBL-producing strains accounted for 35.5% of E. coli peritonitis. The complete cure rate and treatment failure rate of E. coli peritonitis were 77.8% and 10.0% respectively. Patients with preceding peritonitis had a higher risk of ESBL production as compared to those without peritonitis history [odds ratio (OR): 5.286; 95% confidence interval (CI): 2.018 - 13.843; p = 0.001]. The risk of treatment failure was significantly increased when the patient had a baseline score of Charlson Comorbidity Index (CCI) above 3 (OR: 6.155; 95% CI: 1.198 - 31.612; p = 0.03), or had diabetes mellitus (OR: 8.457; 95% CI: 1.838 - 38.91; p = 0.006), or hypoalbuminemia (≤ 30g/l) on admission (OR: 13.714; 95% CI: 1.602 - 117.428; p = 0.01). Prolonging the treatment course from 2 to 3 weeks or more reduced the risk of relapse and repeat significantly (p peritonitis remains a common complication of PD. The clinical outcomes of E. coli peritonitis are relatively favorable despite the high ESBL rate. A history of peritonitis is associated with increased risk for ESBL development. The severity of baseline comorbidities, the presence of diabetes mellitus and hypoalbuminemia at admission are associated

♦ BACKGROUND: Early peritonitis was confirmed to be associated with a higher risk of early technique failure. However, literature concerning peritonitis within the first 3 months of peritoneal dialysis (PD) initiation is scarce. The present study was to investigate risk factors associated with early-onset peritonitis in PD patients. ♦ METHODS: In this retrospective observational cohort study, all incident PD patients from January 1, 2006, to December 31, 2013, were recruited and followed up until December 31, 2014. According to time-to-first episode of peritonitis, patients were divided into early-onset (≤ 3 months) peritonitis and late-onset (> 3 months) peritonitis. Baseline demographic, clinical, and laboratory data, as well as episodes of peritonitis, were collected. Risk factors associated with early-onset peritonitis were evaluated using logistic regression model. ♦ RESULTS: Of 1,690 patients on PD, 503 (29.8%) developed at least 1 episode of peritonitis and 118 (7.0%) patients presented the first episodes of peritonitis within the first 3 months. A multivariate logistic analysis showed that higher body mass index (BMI) (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.01 - 1.15, p = 0.034), hypoalbuminemia (OR 1.75, 95% CI 1.11 - 2.78, p = 0.017), and catheter exit-site infection (OR 4.14, 95% CI 2.45 - 7.00, p peritonitis. Compared to those with late-onset, patients with early-onset peritonitis had a higher overall peritonitis rate (0.76 vs 0.38 per patient-year, p 0.05). ♦ CONCLUSIONS: Higher BMI, hypoalbuminemia, and catheter exit-site infection were the risk factors associated with early-onset peritonitis in PD patients.

Full Text Available INTRODUCTION: Continuous ambulatory peritoneal dialysis (CAPD peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. PATIENTS AND METHODS: We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD, colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. RESULTS: Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4% peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p=0.20. The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; p<0.005. Antibiotic use prior to non-EGD examinations significantly reduced the endoscopy-associated peritonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; p<0.05. Peritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; p<0.05. No peritonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; p<0.05. Although not statistically significant, antibiotics may play a role in preventing gynecologic procedure-related peritonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p=0.10. CONCLUSION: Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such

Acute Peritonitis Caused by Staphylococcus capitis in a Peritoneal Dialysis Patient.

Science.gov (United States)

Basic-Jukic, Nikolina

Acute peritonitis remains the most common complication of peritoneal dialysis (PD), with coagulase-negative staphylococci (CoNS) reported to account for more than 25% of peritonitis episodes (1). Staphylococcus capitis is a gram-positive, catalase-positive CoNS that was originally identified as a commensal on the skin of the human scalp (2). Advancement of microbiological technologies for bacterial identification enables diagnosis of previously unknown causes of acute peritonitis. This is the first reported case of acute peritonitis in a PD patient caused by S. capitis. Copyright © 2017 International Society for Peritoneal Dialysis.

Alexander, H Richard; Li, Claire Yue; Kennedy, Timothy J

2018-02-08

Diffuse malignant peritoneal mesothelioma (MPM) is a rare and ultimately fatal cancer that was first described just over a century ago. It is a diffuse malignancy arising from the mesothelial lining of the peritoneum; morbidity and mortality from MPM is due to its propensity to progress locoregionally within the abdominal cavity. The purpose of this article is to review the current state-of-the-science related to the diagnosis, staging, and treatment of MPM. The condition afflicts men and women equally and the peak incidence is between 55 and 60 years of age although it can arise in the young and elderly. Patients afflicted with MPM most commonly present with nonspecific abdominal symptoms that usually lead to diagnosis when the condition is relatively advanced. Historically, median overall survival for MPM patients without treatment is < 1 year. The couplet of systemic pemetrexed and cisplatin has an overall response rate of approximately 25% and a median overall survival of approximately 1 year. The available data, almost all retrospective in nature, have shown that in selected patients, operative cytoreduction (CRS) and regional chemotherapy administered as hyperthermic intraoperative peritoneal chemotherapy (HIPEC) or early postoperative intraperitoneal chemotherapy (EPIC) is associated with long-term survival. Studies on the molecular biology of MPM have yielded new insights relating to the potentially important role of the phosphoinsitide-3-kinase/mammalian target of rapamycin (PI3 K/mTOR) pathways and immune checkpoint inhibitors that may translate into new therapeutic options for patients with diffuse MPM.

The longitudinal effects of peritoneal dialysis (PD) peritonitis on small solute clearance and ultrafiltration are controversial. We identified 27 patients with PD peritonitis over a 4-year period at a tertiary hospital. Adequacy tests at an "early" (1 - 3 months), "intermediate" (6 ± 2 months), and a "late" (12 ± 2 months) time period after the episode were compared with a pre-peritonitis baseline. The effect of time on serum albumin, weekly creatinine clearance, Kt/V, and net fluid volume removal was assessed. At 12 months, 16/27 (59.3%) patients were no longer on PD. Ten were transferred to hemodialysis, predominantly due to peritonitis (60%). Five patients died, and 1 received a renal allograft. Total daily fluid volume removal significantly decreased over time with an aggregated mean reduction of 523 mL/day between the baseline and 12-month test (1,624 ± 139 mL vs. 1,101 ± 160 mL; p = 0.02). This was due to an equivalent loss of both ultrafiltration and residual urine output, although the separate decline in these individual parameters was not statistically significant. There was no significant change in Kt/V, creatinine clearance, or serum albumin indicating preserved solute transport in those patients with sustained technique survival post peritonitis. Peritonitis is a common cause for transfer to hemodialysis. Fluid volume removal is the most significantly affected parameter at 12 months post peritonitis, driven by the combination of both ultrafiltration reduction and loss of residual diuresis. Clinicians should be aware that peritonitis identifies patients at high risk for technique failure. These findings should prompt clinicians to closely surveil volume status and consider backup dialytic strategies as early as 12 months post peritonitis.

Introduction: Non-Pseudomonas gram-negative bacteria are responsible for an increasing proportion of cases of peritoneal dialysis (PD)-related peritonitis. The role of Citrobacter species in the etiology of PD-related peritonitis is often underestimated. In the present study, we aimed to describe the clinical features, laboratory findings, and short- and long-term outcomes in PD-related peritonitis caused by Citrobacter. Methods: A retrospective review of all episodes of PD-related peritonitis caused by Citrobacter from a single center between 1990 and 2010 was performed. Clinical features, microbiological data, and outcomes of these episodes were analyzed. Results: Citrobacter species was responsible for 11 PD-related episodes (1.8% of all peritonitis episodes) in 8 patients. Citrobacter freundii was the most common etiologic species (73%), and mixed growth was found in the other 3 episodes (27%). Approximately half (46%) of the episodes were associated with constipation and/or diarrhea. Of the Citrobacter isolates from all episodes, 54% were resistant to cefazolin, and only 18% were susceptible to cefmetazole. All isolates were susceptible to ceftazidime, cefepime, carbapenem, and aminoglycosides. More than half of the patients (54%) were hospitalized for index peritonitis, and 27% of the episodes involved a change in antibiotic medication. One patient had relapsing peritonitis caused by C. koseri (9%). The mortality rate of PD-related peritonitis caused by Citrobacter was 18%, and 89% of surviving patients developed technique failure requiring a modality switch after an average of 12 months of follow-up (range 1.2-31.2 months). Conclusion: PD-related peritonitis caused by Citrobacter is associated with poor outcomes, including high rates of antibiotic resistance, a high mortality rate, and a high rate of technique failure among survivors during the follow-up period.

Peritoneal dialysis peritonitis by anaerobic pathogens: a retrospective case series

Science.gov (United States)

2013-01-01

Background Bacterial infections account for most peritoneal dialysis (PD)-associated peritonitis episodes. However, anaerobic PD peritonitis is extremely rare and intuitively associated with intra-abdominal lesions. In this study, we examined the clinical characteristics of PD patients who developed anaerobic peritonitis. Methods We retrospectively identified all anaerobic PD peritonitis episodes from a prospectively collected PD registry at a single center between 1990 and 2010. Only patients receiving more than 3 months of PD were enrolled. We analyzed clinical features as well as outcomes of anaerobic PD peritonitis patients. Results Among 6 patients, 10 episodes of PD-associated peritonitis were caused by anaerobic pathogens (1.59% of all peritonitis episodes during study the period), in which the cultures from 5 episodes had mixed growth. Bacteroides fragilis was the most common species identified (4 isolates). Only 3 episodes were associated with gastrointestinal lesions, and 4 episodes were related to a break in sterility during exchange procedures. All anaerobic pathogens were susceptible to clindamycin and metronidazole, but penicillin resistance was noted in 4 isolates. Ampicillin/sulbactam resistance was found in 2 isolates. In 5 episodes, a primary response was achieved using the first-generation cephalosporin and ceftazidime or aminoglycoside. In 3 episodes, the first-generation cephalosporin was replaced with aminoglycosides. Tenckhoff catheter removal was necessary in 2 episodes. Only one episode ended with mortality (due to a perforated bowel). Conclusion Anaerobic PD-associated peritonitis might be predominantly caused by contamination, rather than intra-abdominal events. Half of anaerobic PD-associated peritonitis episodes had polymicrobial growth. The overall outcome of anaerobic peritonitis is fair, with a high catheter survival rate. PMID:23705895

A 63-year-old woman with no medical history underwent an abdominal surgery with hysterectomy and bilateral salpingo-oophorectomy for a 10 cm peritoneal cyst with increased cancer antigene-125. A large suspicious tumour of the Douglas space, with contact to the uterus and the rectal wall was described. The rest of the exploration was normal, specially the rest of the peritoneum. Histopathology revealed a malignant transformation of a superficial peritoneal endometriosis. Secondary surgery was thus completed by laparoscopy with bilateral pelvic and para-aortic lymph node dissections, omentectomy and multiple peritoneal biopsies. All staging samples were free of cancer; therefore no complementary therapy was administered. After 18 months of follow-up, consisting of clinical examination and pelvis magnetic resonance imaging every 6 months, we did not observe any recurrence. Malignant transformation of superficial peritoneal endometriosis is a rare disease and surgical management seems to be the main treatment.

In spontaneous biliary peritonitis there is perforation in the wall of the extra-hepatic or intra-hepatic duct occurs without any traumatic or iatrogenic injury and have been described more often in neonates. The symptoms may be acute or insidious delaying the diagnosis. Present manuscript deals with diagnosis and management of these cases. Materials and Methods: This is a prospective study and all patients of suspected biliary peritonitis presented during Dec 2010 to Feb 2012 were included in the study. After preliminary investigations in all patients abdominal paracentesis was done and in cases where intra-abdominal fluid bilirubin level was several fold higher than serum bilirubin level were subjected to exploratory laparotomy. Further investigation like T-tube cholangiogram and magnetic resonance cholangiopancreatography (MRCP was done to rule out choledochal cyst before leveling these cases as SPBD. Results: A total of 6 patients were included in present series commonest presenting symptom was progressive abdominal distension without signs of overt peritonitis followed by progressive jaundice, fever and abdominal pain. On exploration site of perforation was observed in 50% of cases and in 50% of cases bile duct was not dilated. Second surgery was not required in 34% of cases. There was no mortality or significant morbidity in our series. Conclusion: Spontaneous perforation of bile duct is rare disease and high index of suspicion is required for diagnosis. Simple bed side test can help in diagnosis but T tube cholangiogram or MRCP are must to rule out choledochal cyst.

Peritoneal carcinomatosis

The peritoneum is a mesothelial lining of the abdominal cavity (parietal) and intraperitoneal viscera (visceral). The cavity contains a small amount of fluid, which circulates from cephalad to caudal to cephalad, influenced by negative pressure under the diaphragm during exhalation, gravity, and bowel peristalsis. Peritoneal reflections and mesenteries divide the cavity into various compartments (supramesocolic, inframesocolic, and pelvis). These reflections support the peritoneal organs and provide vascular and nervous connections while within the cavity they influence pathway of intraperitoneal fluid circulation. Capillary force over convex surfaces influence stasis of fluid and promotes peritoneal seeding; thus, there are numerous areas in which peritoneal masses are seen more commonly. These areas include the undersurface of the diaphragm (negative pressure and capillary force), the omentum (bathed in fluid), the right lower quadrant (oblique course from left superior to right inferior of the small bowel mesentery), the left lower quadrant (transverse course of the sigmoid), and the pelvis (gravity). Peritoneal carcinomatosis may be either primary (mesothelioma) or metastatic. The mode of spread is by direct invasion, lymphatic permeation, peritoneal seeding or hematogenous. The imaging patterns include fibronodular stranding, nodules, plaques, and masses. Mesenteric thickening may produce pleated or stellate patterns. Spiral CT is the most useful modality in diagnosis and follow-up of peritoneal tumors. (orig.)

Micrococcus species-related peritonitis in patients receiving peritoneal dialysis.

Peritonitis is a major complication of peritoneal dialysis (PD) and remains the most common cause of PD failure. Micrococci are catalase-positive, coagulase-negative, and gram-positive cocci that are spherical, often found in tetrad, and belong to the family Micrococcaceae. Micrococcus species are commonly found in the environment, and it is now recognized that Micrococcus species can be opportunistic pathogens in immunocompromised patients. The only consistent predisposing factor for Micrococcus infection is an immunocompromised state. We report three cases of Micrococcus PD peritonitis. Improper practice of PD may have been the causative factor. Although Micrococcus species are low-virulence pathogens, infection could result in refractory peritonitis and subsequent PD failure. Intraperitoneal administration of vancomycin for at least 2 weeks is recommended for Micrococcus peritonitis.

Myths in peritoneal dialysis.

To clarify misconceptions about the feasibility and risks of peritoneal dialysis that unnecessarily limit peritoneal dialysis uptake or continuation in patients for whom peritoneal dialysis is the preferred dialysis modality. The inappropriate choice of haemodialysis as a result of these misconceptions contributes to low peritoneal dialysis penetrance, increases transfer from peritoneal dialysis to haemodialysis, increases expenditure on haemodialysis and compromises quality of life for these patients. Peritoneal dialysis is an excellent renal replacement modality that is simple, cost-effective and provides comparable clinical outcomes to conventional in-centre haemodialysis. Unfortunately, many patients are deemed unsuitable to start or continue peritoneal dialysis because of false or inaccurate beliefs about peritoneal dialysis. Here, we examine some of these 'myths' and critically review the evidence for and against each of them. We review the feasibility and risk of peritoneal dialysis in patients with prior surgery, ostomies, obesity and mesh hernia repairs. We examine the fear of mediastinitis with peritoneal dialysis after coronary artery bypass graft surgery and the belief that the use of hypertonic glucose dialysate causes peritoneal membrane failure. By clarifying common myths about peritoneal dialysis, we hope to reduce overly cautious practices surrounding this therapy.

Residual renal function and the integrity of the peritoneal membrane contribute to morbidity and mortality among patients treated with peritoneal dialysis. Glucose and its degradation products likely contribute to the deterioration of the remnant kidney and damage to the peritoneum. Benfotiamine decreases glucose-induced tissue damage, suggesting the potential for benefit in peritoneal dialysis. Here, in a model of peritoneal dialysis in uremic rats, treatment with benfotiamine decreased peri...

Peritoneal carcinomatosis is a common evolution of neoplasms and the terminal stage of disease. A new therapeutic technique, based on the total surgical removal of peritoneal lesions (peritonectomy procedure - PP) combined with the intraperitoneal chemohyperthermia (IPCH), has been developed. Proper patient selection is mandatory for optimizing the results of treatment. The aim of this study was to investigate the role of [(18)F]fluoro-2-deoxy-d-glucose Positron Emission Tomography/Computed Tomography ((18)F-FDG PET/CT) in patients with peritoneal carcinosis selected to undergo PP and IPCH. Furthermore, we aimed to identify characteristic patterns of abdominal(18)F-FDG uptake and to correlate these patterns with available anatomic findings after surgery. Patients with either histologically confirmed peritoneal carcinosis or suspected upon clinical follow-up and/or imaging findings were prospectively submitted to pre-surgery (18)F-FDG PET/CT scan. Only those patients without evidence of extra-peritoneal metastases at PET/CT scan were treated with PP and IPCH. 11 patients with peritoneal carcinomatosis (5 colorectal, 4 ovarian, 1 pancreatic) and 1 unknown primitive cancer, were eligible for the study. In all cases PET/CT scan showed multiple peritoneal implants. In 6 out of 11 cases (54%) metastases were evidenced by (18)F-FDG PET/CT: 2 cases with liver metastases; 1 case with bone metastases; 3 patients with lymph-node lesions. Two distinct imaging patterns, with focal or diffuse increased (18)F-FDG uptake, were recognized. PP+IPCH of patients selected by (18)F-FDG PET/CT seems to be safe and feasible. PET/CT scan appears as a reliable tool for the detection, characterization of peritoneal implants with potential impact in the therapeutic management of these patients.

Peritonitis is a serious problem in children receiving peritoneal dialysis. Campylobacter jejuni is an unusual cause of peritonitis. A 10-year-old boy who had end stage renal failure due to atypical hemolytic uremic syndrome was admitted to our hospital with abdominal pain and fever. Peritoneal dialysis fluid was cloudy and microscopic examination showed abundant leukocytes. Intraperitoneal cefepime treatment was started. Campylobacter jejuni was isolated from peritoneal dialysis fluid culture and oral clarithromycin was added to the treatment. At the end of therapy, peritoneal fluid culture was negative. To our knowledge, C. jejuni peritonitis was not reported in children previously. Although C. jejuni peritonitis is rarely encountered in children, it should be considered as an etiologic factor for peritonitis. Sociedad Argentina de Pediatría.

Biocompatible Peritoneal Dialysis Fluids: Clinical Outcomes

Full Text Available Peritoneal dialysis (PD is a preferred home dialysis modality and has a number of added advantages including improved initial patient survival and cost effectiveness over haemodialysis. Despite these benefits, uptake of PD remains relatively low, especially in developed countries. Wider implementation of PD is compromised by higher technique failure from infections (e.g., PD peritonitis and ultrafiltration failure. These are inevitable consequences of peritoneal injury, which is thought to result primarily from continuous exposure to PD fluids that are characterised by their “unphysiologic” composition. In order to overcome these barriers, a number of more biocompatible PD fluids, with neutral pH, low glucose degradation product content, and bicarbonate buffer have been manufactured over the past two decades. Several preclinical studies have demonstrated their benefit in terms of improvement in host cell defence, peritoneal membrane integrity, and cytokine profile. This paper aims to review randomised controlled trials assessing the use of biocompatible PD fluids and their effect on clinical outcomes.

To evaluate the CT findings of peritonitis associated with continuous ambulatory peritoneal dialysis(CAPD). We retrospectively analyzed CT scans of 14 symptomatic patients with peritonitis after CAPD. Diffuse abdominal pain was present in 11, fever in two, and abdominal mass with vomiting in one. The mean duration of CAPD ranged from 10 months to 5 years(mean : 3.9 years). On abdominal CT, we evaluated the presence and location of ascites, bowel wall thickening, cocoon formation, the pattern of enhancement of peritoneal thickening, the presence of calcifications in the peritoneum, and mesenteric and omental change. On enhanced CT, multiloculated ascites was observed in all cases(n=14) ; it was located mainly in the pelvic cavity with small multi-loculated fluid collections in the peritoneal cavity(n=13), including the lesser sac(n=3). In one patient, ascites was located in the space between the greater omentum and anterior peritoneal surface. CT showed ileus in 12 cases, small bowel wall thickening in 11, and cocoon formation in five. Uneven but smooth thickening of the peritoneum, with contrast enhancement, was seen in eight cases, and in five of these, peritoneal thickening was more prominent in the anterior peritoneum. Other findings included reticular opacity in two cases, hematoma of the rectus muscle in one, and umbilical hernia in one. Multiloculated fluid collection, ileus, small bowel wall thickening, uneven but smooth peritoneal thickening, and cocoon formation appear to be CT features of CAPD peritonitis.

♦ Introduction: Peritonitis remains the main cause of peritoneal dialysis (PD) technique failure worldwide, despite significant reductions in infection rates observed over the past decades. Several studies have described risk factors for peritonitis, technique failure and mortality. However, there are scarce data regarding predictors of complications during and after a peritonitis episode. The aim of our study was to analyze predictors of peritonitis-related outcome in the Brazilian Peritoneal Dialysis study (BRAZPD) cohort. ♦ Methods: All adult incident patients recruited in the BRAZPD Study between December 2004 and October 2007, who remained at least 90 days on PD and presented their first peritonitis episode (n = 474 patients) were included in the study. The endpoints analyzed were non-resolution, death due to a peritonitis episode and long-term technique survival after a peritonitis episode. ♦ Results: In the multivariable regression, non-resolution was independently associated with older age (odds ratio (OR) 1.02; p peritonitis therapy presented a higher risk of non-response (OR 2.5; p peritonitis episode was older age (OR 1.04; p peritonitis on outcomes, we observed that collagenosis may negatively impact response to treatment and exposure to vancomycin may possibly reduce long-term technique survival. It is important to emphasize that the association of vancomycin with technique failure does not prove causality. These findings shed light on new factors predicting outcome when peritonitis is diagnosed. PMID:24385333

Treatment of Enterococcal Peritonitis in Peritoneal Dialysis Patients by Oral Amoxicillin or Intra-Peritoneal Vancomcyin: a Retrospective Study

Full Text Available Background/Aims: Enterococcal peritonitis in peritoneal dialysis (PD patients is associated with a high complication rate. The optimal treatment regimen of PD-related enterococcal peritonitis is controversial. The latest international guideline recommends intra-peritoneal (IP vancomycin. Although ampicillin is often effective for systemic enterococcal infections, they have little in vitro activity when added to common PD solutions. Since oral amoxicillin achieves therapeutic drug level in the peritoneal cavity, we explore the efficacy of oral amoxicillin for enterococcal peritonitis. Methods: We studied 105 episodes of enterococcal peritonitis over 20 years in our unit; 43 (41.0% were treated with oral amoxicillin, and 62 (59.0% with IP vancomycin. Their clinical outcome was reviewed. Result: The overall primary response rate to oral amoxicillin and IP vancomycin was 76.4% and 85.5%, respectively (p = 0.3. The complete cure rate of oral amoxicillin and IP vancomycin was 55.8% and 54.8%, respectively (p = 0.8. When the 5 episodes of ampicillin-resistant Enterococcus episodes were excluded, the primary response rate and complete cure rate of oral amoxicillin were 86.8% and 63.2%, respectively. Conclusion: Oral amoxicillin has an excellent primary response rate and complete cure rate for PD-related peritonitis episodes caused by Enterococcus species, indicating that oral amoxicillin is a valid and convenient therapeutic option for enterococcal peritonitis episodes.

Cell-free DNA (cfDNA) is present in the peritoneal effluent of stable peritoneal dialysis (PD) patients, but there are no data on cfDNA in PD patients with peritonitis. We investigated the variation of peritoneal cfDNA levels subsequent to peritonitis in PD patients. We enrolled 53 PD patients: 30 without any history of systemic inflammation or peritonitis in the last 3 months (group A) and 23 with acute peritonitis (group B). CfDNA was quantified in the peritoneal effluent. Peritoneal samples on days 1, 3, 10, 30 and until day 120 from the start of peritonitis were collected for white blood cells (WBC) count and cfDNA evaluation in group B. Quantitative analysis of cfDNA showed significantly higher levels in group B on day 1, 3, 10 and 30 compared with group A (p peritoneal cfDNA levels tended to progressively decline during follow-up of peritonitis. From this decreasing curve, we estimated that 49 days are necessary to reach the value of 51 genome equivalents (GE)/ml (75th percentile in controls) and 63 days to reach 31 GE/ml (median). Our results demonstrate that cfDNA increases in peritoneal effluent of PD patients with peritonitis and tends to progressively decline in step with peritonitis resolution and membrane repair process. Peritoneal cfDNA quantification could be an innovative method to determine acute damage and an inverse index of the repair process.

Background Acinetobacter species are assuming an increasingly important role in modern medicine, with their persistent presence in health-care settings and antibiotic resistance. However, clinical reports addressing this issue in patients with peritoneal dialysis (PD) peritonitis are rare. Methods All PD peritonitis episodes caused by Acinetobacter that occurred between 1985 and 2012 at a single centre were retrospectively reviewed. Clinical features, microbiological data, and outcomes were analysed, with stratifications based upon temporal periods (before and after 2000). Results Acinetobacter species were responsible for 26 PD peritonitis episodes (3.5% of all episodes) in 25 patients. A. baumannii was the most common pathogen (54%), followed by A. iwoffii (35%), with the former being predominant after 2000. Significantly more episodes resulted from breaks in exchange sterility after 2000, while those from exit site infections decreased (P = 0.01). The interval between the last and current peritonitis episodes lengthened significantly after 2000 (5 vs. 13.6 months; P = 0.05). All the isolates were susceptible to cefepime, fluoroquinolone, and aminoglycosides, with a low ceftazidime resistance rate (16%). Nearly half of the patients (46%) required hospitalisation for their Acinetobacter PD-associated peritonitis, and 27% required an antibiotic switch. The overall outcome was fair, with no mortality and a 12% technique failure rate, without obvious interval differences. Conclusions The temporal change in the microbiology and origin of Acinetobacter PD-associated peritonitis in our cohort suggested an important evolutional trend. Appropriate measures, including technique re-education and sterility maintenance, should be taken to decrease the Acinetobacter peritonitis incidence in PD patients. PMID:25314341

Full Text Available Lactobacillus species colonize the human gastrointestinal tract and are rarely pathogenic. We present a case involving a cirrhotic patient who presented with sepsis and was found to have peritoneal cultures demonstrating Lactobacillus as the sole pathogen concerning for spontaneous bacterial peritonitis. Treatment was achieved with high-dose penicillin and clindamycin but the patient developed hepatorenal syndrome and died from acute renal failure. Intra-abdominal Lactobacillus infections are typically seen in patients undergoing peritoneal dialysis or who have recently had bowel perforation. There are few case reports of spontaneous Lactobacillus peritonitis in patients with cirrhosis. Our case report addresses the challenges of Lactobacillus treatment and suggests antibiotic coverage of commensal organisms in patients who do not improve with standard management.

Introduction Continuous ambulatory peritoneal dialysis (CAPD) peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. Patients and methods We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD), colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD) implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. Results Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4%) peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p = 0.20). The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; pperitonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; pPeritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; pperitonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; pperitonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p = 0.10). Conclusion Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such as biopsy, polypectomy, IUD implantation/removal, and dilatation and curettage (D&C), pose a high risk for peritonitis. Prophylactic antibiotics for peritonitis prevention may be required in colonoscopic procedures and gynecologic procedures

Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications. In the management of refractory peritonitis, pelvic drainage during removal of dialysis catheter decreases the risk of subsequent intra-abdominal complications and invasive interventions. © 2015 Asian Pacific Society of Nephrology.

Few studies discuss causes and outcomes of peritonitis in low-income settings. This study describes epidemiology of patients with peritonitis at a Rwandan referral hospital. Identification of risk factors associated with mortality and unplanned reoperation could improve management of peritonitis. Data were collected on demographics, clinical presentation, operative findings, and outcomes for all patients with peritonitis. Multivariate regression analysis identified factors associated with in-hospital mortality and unplanned reoperation. A total of 280 patients presented with peritonitis over a 6-month period. Causes of peritonitis were complications of intestinal obstruction (39%) and appendicitis (17%). Thirty-six (13%) patients required unplanned reoperation, and in-hospital mortality was 17%. Factors associated with increased odds of in-hospital mortality were unplanned reoperation (adjusted odds ratio 34.12), vasopressor use (adjusted odds ratio 24.91), abnormal white blood cell count (adjusted odds ratio 12.6), intensive care unit admission (adjusted odds ratio 9.06), and American Society of Anesthesiologist score ≥3 (adjusted odds ratio 7.80). Factors associated with increased odds of unplanned reoperation included typhoid perforation (adjusted odds ratio 5.92) and hypoxia on admission (adjusted odds ratio 3.82). Peritonitis in Rwanda presents with high morbidity and mortality. Minimizing delays in care is important, as many patients with intestinal obstruction present with features of peritonitis. A better understanding of patient care and management prior to arrival at the referral hospital is needed to identify areas for improvement at the health center and district hospital.

Previous imaging reports of peritoneal mesothelioma have described a variety of radiologic appearances, but have not included its pathologic classification. We retrospectively reviewed 10 cases of peritoneal mesothelioma representing the following histologic categories: 7 epithelial, 2 sarcomatoid, and one biphasic. By imaging, epithelial mesotheliomas demonstrated diffuse thickening of the peritoneum and mesentery and/or multiple small nodules. The sarcomatoid-type appeared as a mass and the biphasic-type had radiologic and gross pathologic features of both sarcomatoid and epithelial types. We conclude that peritoneal mesothelioma presents with a wide spectrum of radiographic appearances and should therefore be included in the differential diagnoses of diffuse as well as localized peritoneal processes.

Peritoneal seeding of colon cancer cells is a common cause of morbidity and eventual mortality with recurrent disease. This study evaluated the role of F -18 FDG PET in detecting peritoneal seeding in colorectal carcinoma (CRC and to identify characteristic patterns of abdominal F-18 FDG uptake. We reviewed the FDG PET and CT images and clinical charts of 49 patients with peritoneal seeding and 22 cancer patients without peritoneal seeding. We also assessed FDG PET scans from 20 healthy volunteers as a baseline study. The maximum standardised uptake values (SUVmax) over peritoneal lesions in cancer patients and over the area of most intense intestinal uptake in healthy volunteers and cancer patients without peritoneal carcinomatosis were measured. The result were correlated with either biopsy or ascitic aspirate. The characteristics of FDG uptake were evaluated: overall pattern (focal or diffuse), heterogeneity (yes or none), intensity (low, or equal, faint to moderate, intense). The sensitivity and positive predictive value (PPV) of FDG PET were superior to CT for the detection of peritoneal lesions (sensitivity: 71.4% vs 57.1%, specificity: 72.7% vs 54.5%: PPV: 85.4% vs 73.7%, NPV: 53.3 % vs 36.4% ). The FDG uptake in patients with peritoneal carcinomatosis was divided into nodular(14), diffuse (23) and mixed pattern (12). An SUVmax threshold of 5.2 produced a diagnostic accuracy of FDG PET of 78%. The additional information provided by FDG PET allowed a more accurate diagnosis in 12 patients (24 %), and led to alteration of the therapeutic strategy in 6 (12.2%) of the enrolled patients (n=49) with peritoneal seeding. FDG-PET was more sensitive than CT for the detection of peritoneal seeding in CRC, and altered patient management. Thus, the application of PET may be beneficial to the management of peritoneal seeding in patient with CRC.

Peritoneal dialysis (PD) is a home therapy, and technique survival is related to the adherence to PD prescription at home. The presence of a home visit program could improve PD outcomes. We evaluated its effects on clinical outcome during 1 year of follow-up. This was a case-control study. The case group included all 96 patients who performed PD in our center on January 1, 2013, and who attended a home visit program; the control group included all 92 patients who performed PD on January 1, 2008. The home visit program consisted of several additional visits to reinforce patients' confidence in PD management in their own environment. Outcomes were defined as technique failure, peritonitis episode, and hospitalization. Clinical and dialysis features were evaluated for each patient. The case group was significantly older (p = 0.048), with a lower grade of autonomy (p = 0.033), but a better hemoglobin level (p = 0.02) than the control group. During the observational period, we had 11 episodes of technique failure. We found a significant reduction in the rate of technique failure in the case group (p = 0.004). Furthermore, survival analysis showed a significant extension of PD treatment in the patients supported by the home visit program (52 vs. 48.8 weeks, p = 0.018). We did not find any difference between the two groups in terms of peritonitis and hospitalization rate; however, trends toward a reduction of Gram-positive peritonitis rates as well as prevalence and duration of hospitalization related to PD problems were identified in the case group. The retrospective nature of the analysis was a limitation of this study. The home visit program improves the survival of PD patients and could reduce the rate of Gram-positive peritonitis and hospitalization.

Bacterial peritonitis remains the main cause of technique failure in peritoneal dialysis (PD). During peritonitis, the peritoneal membrane undergoes structural and functional alterations that are mediated by IL-1 β The NLRP3 inflammasome is a caspase-1-activating multiprotein complex that links sensing of microbial and stress products to activation of proinflammatory cytokines, including IL-1 β The potential roles of the NLRP3 inflammasome and IL-1 β in the peritoneal membrane during acute peritonitis have not been investigated. Here, we show that the NLRP3 inflammasome is activated during acute bacterial peritonitis in patients on PD, and this activation associates with the release of IL-1 β in the dialysate. In mice, lipopolysaccharide- or Escherichia coli -induced peritonitis led to IL-1 β release in the peritoneal membrane. The genetic deletion of Nalp3 , which encodes NLRP3, abrogated defects in solute transport during acute peritonitis and restored ultrafiltration. In human umbilical vein endothelial cells, IL-1 β treatment directly enhanced endothelial cell proliferation and increased microvascular permeability. These in vitro effects require endothelial IL-1 receptors, shown by immunofluorescence to be expressed in peritoneal capillaries in mice. Furthermore, administration of the IL-1 β receptor antagonist, anakinra, efficiently decreased nitric oxide production and vascular proliferation and restored peritoneal function in mouse models of peritonitis, even in mice treated with standard-of-care antibiotherapy. These data demonstrate that NLRP3 activation and IL-1 β release have a critical role in solute transport defects and tissue remodeling during PD-related peritonitis. Blockade of the NLRP3/IL-1 β axis offers a novel method for rescuing morphologic alterations and transport defects during acute peritonitis. Copyright © 2017 by the American Society of Nephrology.

♦ This study was carried out to examine whether or not elderly patients on peritoneal dialysis (PD) had an increased risk of peritonitis. ♦ This was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 8,396 incident patients starting PD between January 2003 and December 2010. The end of the observation period was 31 December 2012. Patients were separated into 2 age groups: up to 75 and over of 75 years old. ♦ Among 8,396 patients starting dialysis there were 3,173 patients older than 75. When using a Cox model, no association was found between age greater than 75 years and increased risk of peritonitis (hazard ratio [HR]: 0.97 [0.88 - 1.07]). Diabetes (HR: 1.14 [1.01 - 1.28] and continuous ambulatory PD (HR: 1.13 [1.04 - 1.23]) were significantly associated with a higher risk of peritoneal infection whereas nurse-assisted PD was associated with a lower risk of peritonitis (HR: 0.85 [0.78 - 0.94]. In the analysis restricted to the 3,840 self-care PD patients, there was no association between age older than 75 years and risk of peritonitis. ♦ The risk of peritonitis is not increased in elderly patients on PD in a country where assisted PD is available.

118 episodes of infectious peritonitis registered among 156 patients treated with intermittent peritoneal dialysis over a 5-yr period were analysed with special reference to potential routes of infection associated with the dialysis catheter. Peritonitis was randomly distributed among the patients......, and the change of keeping free of peritonitis declined exponentially with time. The main factor determining the individual number of episodes was the total space of time, in which a patient had been wearing a dialysis catheter, whereas the number of catheter disconnections played no significant role.

We present a case where Bacillus cereus was determined to be the causative agent of relapsing peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD). The patient, a 70-year-old man from the Faroe Islands, was admitted with relapsing peritonitis four times over a 3-month period....... Peritoneal cultures were positive for growth of B. cereus, a rare bacterial cause of peritonitis. The cultures demonstrated susceptibility to vancomycin, and therefore the patient was treated with intraperitoneal vancomycin, intraperitoneal gentamycin and oral ciprofloxacin. As a result of the relapsing B....... cereus peritonitis diagnosis and a CT scan showing contraction of the peritoneum after longstanding inflammation, the peritoneal catheter was removed and the patient converted to haemodialysis. To date, the patient has not been readmitted due to peritonitis. A lack of proper hygiene when changing...

Peritoneal membrane function can be assessed using the peritoneal equilibration test (PET) and similar tests, but these are almost always complicated to use, require a considerable amount of working time and their results cannot always be easily interpreted. Ionic conductivity is a measure of the ability of an electrolyte solution to conduct electricity. We tested the hypothesis that the ionic conductivity of peritoneal dialysate can be used to evaluate peritoneal membrane function in peritoneal dialysis patients. We measured the ionic conductivity and classic biochemical parameters of peritoneal dialysate in 69 patients during a modified PET and compared their ability to evaluate peritoneal membrane function and to diagnose ultrafiltration failure (UFF). Ionic conductivity was correlated well with classical parameters of peritoneal transport as glucose reabsorption of glucose (D/D0: r(2) = 0.62, P conductivity area under the receiver-operating characteristic curve was 0.91 (95% confidence interval: 0.81-0.96) with sensitivity of 1.00 and specificity of 0.84 at a cut-off value of 12.75 mS/cm. These findings indicate that the ionic conductivity of peritoneal dialysate can be used as a new screening tool to evaluate peritoneal membrane function. © The Author 2015.

Pleuroperitoneal leak complicating peritoneal dialysis: a case series.

LENUS (Irish Health Repository)

Kennedy, C

2012-02-01

Pressure related complications such as abdominal wall hernias occur with relative frequency in patients on peritoneal dialysis. Less frequently, a transudative pleural effusion containing dialysate can develop. This phenomenon appears to be due to increased intra-abdominal pressure in the setting of congenital or acquired diaphragmatic defects. We report three cases of pleuroperitoneal leak that occurred within a nine-month period at our institution. We review the literature on this topic, and discuss management options. The pleural effusion resolved in one patient following drainage of the peritoneum and a switch to haemodialysis. One patient required emergency thoracocentesis. The third patient developed a complex effusion requiring surgical intervention. The three cases highlight the variability of this condition in terms of timing, symptoms and management. The diagnosis of a pleuroperitoneal leak is an important one as it is managed very differently to most transudative pleural effusions seen in this patient population. Surgical repair may be necessary in those patients who wish to resume peritoneal dialysis, or in those patients with complex effusions. Pleuroperitoneal leak should be considered in the differential diagnosis of a pleural effusion, particularly a right-sided effusion, in a patient on peritoneal dialysis.

OBJECTIVE: The purpose of this article is to present the spectrum of radiologic findings of encapsulating peritoneal sclerosis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). CONCLUSION: Although a rare diagnosis, encapsulating peritoneal sclerosis in patients undergoing CAPD has a high morbidity and mortality. Diagnosis is often delayed because clinical features are insidious and nonspecific. Radiologic imaging may be helpful in the early diagnosis of encapsulating peritoneal sclerosis and in facilitating timely intervention for CAPD patients with encapsulating peritoneal sclerosis.

Peritoneal carcinomatosis (PC) is a cancer disease with an urgent need for effective treatment. Conventional chemotherapy failed to show acceptable results. Cytoreductive surgery and hyperthermic chemoperfusion (HIPEC) are only beneficial in few patients with resectable peritoneal metastasis. Immunotherapy could be attractive against PC, as all requirements for immunotherapy are available in the peritoneal cavity. This review analyzes the present literature for immunotherapy of PC. Advances from immune stimulators, radionucleotide-conjugated- and bispecific antibodies to future developments like adoptive engineered T-cells with chimeric receptors are discussed. The clinical development of catumaxomab, which was the first intraperitoneal immunotherapy to be approved for clinical treatment, is discussed. The requirements for future developments are illustrated. Expert commentary: Immunotherapy of peritoneal carcinomatosis is manageable, showing striking cancer cell killing. Improved profiles of adverse events by therapy-induced cytokine release, enhanced specific killing and optimal treatment schedules within multimodal treatment will be key factors.

Full Text Available High mobility group box 1 (HMGB1, a DNA-binding nuclear protein, has been implicated as an endogenous danger signal in the pathogenesis of infection diseases. However, the potential role and source of HMGB1 in the peritoneal dialysis (PD effluence of patients with peritonitis are unknown. First, to evaluate HMDB1 levels in peritoneal dialysis effluence (PDE, a total of 61 PD patients were enrolled in this study, including 42 patients with peritonitis and 19 without peritonitis. Demographic characteristics, symptoms, physical examination findings and laboratory parameters were recorded. HMGB1 levels in PDE were determined by Western blot and ELISA. The concentrations of TNF-α and IL-6 in PDE were quantified by ELISA. By animal model, inhibition of HMGB1 with glycyrrhizin was performed to determine the effects of HMGB1 in LPS-induced mice peritonitis. In vitro, a human peritoneal mesothelial cell line (HMrSV5 was stimulated with lipopolysaccharide (LPS, HMGB1 extracellular content in the culture media and intracellular distribution in various cellular fractions were analyzed by Western blot or immunofluorescence. The results showed that the levels of HMGB1 in PDE were higher in patients with peritonitis than those in controls, and gradually declined during the period of effective antibiotic treatments. Furthermore, the levels of HMGB1 in PDE were positively correlated with white blood cells (WBCs count, TNF-α and IL-6 levels. However, pretreatment with glycyrrhizin attenuated LPS-induced acute peritoneal inflammation and dysfunction in mice. In cultured HMrSV5 cells, LPS actively induced HMGB1 nuclear-cytoplasmic translocation and release in a time and dose-dependent fashion. Moreover, cytosolic HMGB1 was located in lysosomes and secreted via a lysosome-mediated secretory pathway following LPS stimulation. Our study demonstrates that elevated HMGB1 levels in PDE during PD-related peritonitis, at least partially, from peritoneal mesothelial cells

The peritoneum is a frequent site of involvement by peritoneal tuberculosis. Generally, computed tomography appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis. The computed tomography findings can help in the diagnosis of peritoneal tuberculosis, that is confirmed by a positive culture or hystologic analysis of biopsy obtained through laparoscopic examination. Peritoneal carcinomatosis is the main differential diagnosis. In this article we present the spectrum of tomographic manifestation of peritoneal tuberculosis and how we can differentiate it from peritoneal carcinomatosis. (author)

To analyze the clinical characteristics of continuous ambulatory peritoneal dialysis (CAPD) associated peritonitis in the tertiary hospitals and to discuss the preventive and therapeutic strategy.
 Methods: The clinical characteristics, pathogens, resistance and outcomes of 126 CAPD associated peritonitis in 104 patients from Jan, 2013 to June, 2016, were retrospectively analyzed.
 Results: Among the patients, the incidence rates of abdominal pain, fever, diarrhea and emesis were 104 (82.54%), 56 (44.44%), 49 (38.89%), and 31 (23.60%), respectively. Among them, 88 patients suffered peritonitis once, other 16 patients suffered multiple peritonitis or recurrent peritonitis for 38 times. Among the 38 times, the numbers for recurrent, repeated or catheter-associated peritonitis were 2, 2, or 3, respectively. Peritoneal fluids from 103 cases were cultured, and 64 cases were positive in bacteria, with a rate of 62.14%. A total of 70 strains of bacteria were separated, including 42 strains of gram-positive bacteria, 21 strains of gram-negative bacteria, and 7 strains of fungus. The most common gram-positive pathogens were Staphylococcus epidermidis, Enterococcus faecalis and Staphylococcus haemolyticus, while Escherichia coli, Klebsiella pneumoniae and Klebsiella pneumoniae were the most common gram-negative bacteria. Candida albicans was the major fungal pathogens. Gram-positive cocci showed resistance to gentamycin, levofloxacin, moxifloxacin, vancomycin and linezolid, with a rate at 20.00%, 36.11%, 5%, 0%, and 0%, respectively. The gram-negative bacilli were resistent to cefoperazone/sulbactam, gentamycin, cephazolin, and ceftazidime, with a rate at 6.25%, 10.53%, 64.29%, and 15.38%, respectively. There were no imipenem, amikacin, piperacillin/tazobactam-resistant strains were found.
 Conclusion: The most common pathogen causing CAPD associated peritonitis is gram-positive bacteria. It is crucial to take the anti-infection therapy for CAPD associated peritonitis

Full Text Available During peritoneal dialysis (PD, the peritoneal membrane undergoes ageing processes that affect its function. Here we analyzed associations of patient age and dialysis vintage with parameters of peritoneal transport of fluid and solutes, directly measured and estimated based on the pore model, for individual patients. Thirty-three patients (15 females; age 60 (21–87 years; median time on PD 19 (3–100 months underwent sequential peritoneal equilibration test. Dialysis vintage and patient age did not correlate. Estimation of parameters of the two-pore model of peritoneal transport was performed. The estimated fluid transport parameters, including hydraulic permeability (LpS, fraction of ultrasmall pores (αu, osmotic conductance for glucose (OCG, and peritoneal absorption, were generally independent of solute transport parameters (diffusive mass transport parameters. Fluid transport parameters correlated whereas transport parameters for small solutes and proteins did not correlate with dialysis vintage and patient age. Although LpS and OCG were lower for older patients and those with long dialysis vintage, αu was higher. Thus, fluid transport parameters—rather than solute transport parameters—are linked to dialysis vintage and patient age and should therefore be included when monitoring processes linked to ageing of the peritoneal membrane.

1992-01-01

We report an outbreak of fungal peritonitis due to Candida parapsilosis in 12 patients undergoing chronic ambulatory peritoneal dialysis (CAPD). All 12 patients were treated by removal of the CAPD catheter together with systemic antifungal therapy. There were no peritonitis-related deaths. Four patients were successfully returned to CAPD at a later date. Microbiological investigation during the outbreak demonstrated colonization of various areas of the CAPD Unit and medical ward with the organism. C. parapsilosis was also isolated from pigeon guano obtained from window-sills. The number of cases of peritonitis due to this organism decreased markedly after bird-proof netting was installed. We believe that this is the first report of an outbreak of CAPD peritonitis due to faecal carriage of C. parapsilosis by pigeons.

Introduction: Perforation peritonitis mostly results from the perforation of a diseased viscus. Other causes of perforation include abdominal trauma, ingestion of sharp foreign body and iatrogenic perforation. The diagnosis is mainly based on clinical grounds. Plain abdominal X-rays (erect) may reveal dilated and oedematous intestines with pneumoperitoneum. Ultrasound and CT scan may diagnose up to 72% and 82% of perforation respectively. The present study was carried out to study various etiological factors, modes of clinical presentation, morbidity and mortality patterns of perforation peritonitis presented in the RIMS hospital, Imphal, India. Material and Methods: The study was conducted from September 2010 to August 2012 on 490 cases of perforation peritonitis admitted and treated in the Department of Surgery. Initial diagnosis was made on the basis of detailed history, clinical examination and presence of pneumoperitoneum on erect abdominal X-ray. Results: A total of 490 patients of perforation peritonitis were included in the study, with mean age of 48.28 years. 54.29% patients were below 50 years and 45.71% patients were above 50 years. There were 54.29% male patients and 45.71% female patients. Only 30% patients presented within 24 hours of onset of symptoms, 31.43% patients presented between 24 to 72 hours and 38.57% patients presented 72 hours after the onset of symptoms. Mean duration of presentation was 54.7 hours. Overall 469 patients were treated surgically and 21 patients were managed conservatively. Overall morbidity and mortality recorded in this study were 52.24% and 10% respectively. PMID:24392388

♦ Objective: Peritoneal dialysis (PD) has become more prevalent as a treatment modality for end-stage renal disease, and peritonitis remains one of its most devastating complications. The aim of the present investigation was to examine the frequency and predictors of peritonitis and the impact of peritonitis on clinical outcomes. ♦ Methods: Our retrospective observational cohort study enrolled 391 patients who had been treated with continuous ambulatory PD (CAPD) for at least 90 days. Relevant demographic, biochemical, and clinical data were collected for an analysis of CAPD-associated peritonitis, technique failure, drop-out from PD, and patient mortality. ♦ Results: The peritonitis rate was 0.196 episodes per patient-year. Older age (>65 years) was the only identified risk factor associated with peritonitis. A multivariate Cox regression model demonstrated that technique failure occurred more often in patients experiencing peritonitis than in those free of peritonitis (p peritonitis tended to survive longer than the group that was peritonitis-free (p = 0.11). After multivariate adjustment, the survival advantage reached significance (hazard ratio: 0.64; 95% confidence interval: 0.46 to 0.89; p = 0.006). Compared with the peritonitis-free group, the group experiencing peritonitis also had more drop-out from PD (p = 0.03). ♦ Conclusions: The peritonitis rate was relatively low in the present investigation. Elderly patients were at higher risk of peritonitis episodes. Peritonitis independently predicted technique failure, in agreement with other reports. However, contrary to previous studies, all-cause mortality was better in patients experiencing peritonitis than in those free of peritonitis. The underlying mechanisms of this presumptive “peritonitis paradox” remain to be clarified. PMID:24084840

Peritonism is a finding that leads to a more cautious approach in the emergency department management of abdominal pain. This study examined whether peritonism assessment using inspiration, expiration and cough tests was associated with the patient's clinical management. This prospective observational study evaluated consecutive patients presenting directly to the emergency department for 3 months from June 2000 with abdominal pain. Triage initial observations of blood pressure, pulse, respiratory rate, oxygen saturation and temperature were recorded. The examining emergency physician recorded each patient's response and pain score to the individual peritonism tests and scored it as positive if there was an indication of it being a painful manoeuvre. The results were blinded from the receiving specialty if subsequent referral was required. Sixty-seven patients had peritonism tests performed. No individual test was more painful than the others with similar values in pain scores. In all, 70% (7/10) were admitted when all three tests were positive, compared with 21% (12/57) when two or less of the tests scored positive (P=0.004, Fisher's exact test). Admission was not associated with any individual test or combination of tests, or any other variable. The peritonism tests were not associated with any other physiological observation or measurement. These peritonism tests represent a simple investigation, and are significantly associated with admission when all three tests are positive. They seem to be a clinical predictor of cases in which continuing assessment was required, and may be useful as a departmental 'safety net' in the management of abdominal pain.

Fungal peritonitis is a major complication of peritoneal dialysis associated with high mortality. Most survivors have a high rate of abandonment of peritoneal dialysis. We report a case of fungal peritonitis due to an unusual agent. An 83 year-old woman, with a history of type 2 diabetes mellitus and multiple episodes of bacterial peritonitis associated to technical flaws in the implementation of automated peritoneal dialysis, was admitted due to abdominal pain and cloudy peritoneal fluid. Rhodotorula mucilaginosa was identified in the peritoneal fluid by MALDI-TOF. She was treated with catheter removal and oral posaconazole for 14 days showing clinical resolution and non-recurrence.

Laparoscopy has gained clinical acceptance in many subspecialties in the last decade. The conventional open surgery for peritonitis carries significant morbidity and mortality. The present study was done to extend and evaluate benefits of minimally invasive surgery in this subset of patients. This was a prospective study spanning over a period of four years. All those patients diagnosed as having peritonitis on clinical assessment and preoperative investigations and those who were stable enough haemodynamically were included in this study. After initial resuscitation for few hours, they underwent diagnostic and therapeutic laparoscopy to identify the cause of peritonitis and to confirm the pathology. All cases were done under general anesthesia, using three standard ports at appropriate sites according to pathology. Patients were treated by different procedures either laparoscopically or with laparoscopic assistance after diagnosis. Operative and post operative data was collected and analyzed. Ninety two cases of peritonitis underwent diagnostic and therapeutic laparoscopy. Mean age of patient was 46.5 years. 24 patients were diagnosed as perforated duodenal, in 14 (58.3%) patients laparoscopic suture repair was done and in 8 (33.3%) small upper midline incision was given and perforation was repaired. Out of 32 patients having perforated appendix, 25 (78.1%) patients laparoscopic appendectomy was done while in 7 (21.8%) perforation was dealt by laparoscopic assistance. Out of 14 patients of ileal perforation 6 (42.8%) with minimal contamination laparoscopic suture was applied, while in 8 (57.1%), perforated loop was brought out by making small window and perforation was closed. All 22 patients with pelvic sepsis needed only aspiration of pus and peritoneal lavage. Only one patient died post operatively and 2 (2.1%) patients developed fistula. 6 (6.5%) patients developed port site infection. Laparoscopic management is feasible, safe and effective surgical option for

Diabetic patients treated by peritoneal dialysis (PD) have been reported to be at an increased risk of peritonitis. This has been attributed to impairment in host defense, visual impairment, disability and muscle wasting, which could compromise ability to safely perform catheter connections. This study aimed to evaluate whether assisted PD is associated with a lower risk of peritonitis in diabetic patients. This was a retrospective study based on data from the French Language Peritoneal Dialysis Registry. We included diabetic patients starting PD between 1 January 2002 and 31 December 2012. The end of the observation period was 31 December 2013. Using complementary regression analysis (Fine and Gray, Hurdle models), we assessed the relationship between peritonitis occurrence, peritonitis number over time and the type of assisted PD. Of the 3598 diabetic patients, there were 2040 patients on nurse-assisted PD. These patients were older, more comorbid and more frequently on continuous ambulatory peritoneal dialysis (CAPD). In the multivariate analysis, nurse assistance was associated with a reduced risk of peritonitis in the Fine and Gray [subdistribution hazard ratio: 0.78 (95% confidence interval, CI, 0.68-0.89)] and in the first component of the Hurdle models [rate ratio: 0.82 (95% CI 0.71-0.93)], but not a lower incidence of peritonitis after an initial episode [rate ratio: 0.82 (95% CI 0.95-1.38)]. Transplant failure, glomerulonephritis and CAPD were associated with an increased risk. In France, nurse-assisted PD is associated with a lower risk of peritonitis in diabetic patients treated by PD but not a lower incidence of peritonitis. © The Author 2016.

Abstract Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients’ technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its effects on clinical outcomes in CAPD patients. This is a single center, retrospective, observational cohort study. A total of 294 patients who developing at least 1 episode of peritonitis were followed up from March 1st, 2002, to July 31, 2014, in our PD center. Multivariate logistic regression was used to determine the factors associated with HPR, and the Cox proportional hazard model was conducted to assess the effects of HPR on clinical outcomes. During the study period of 2917.5 patient-years, 489 episodes of peritonitis were recorded, and the total peritonitis rate was 0.168 episodes per patient-year. The multivariate analysis showed that factors associated with HPR include a quick occurrence of peritonitis after CAPD initiation (shorter than 12 months), and a low serum albumin level at the start of CAPD. In the Cox proportional hazard model, HPR was a significant predictor of technique failure. There were no differences between HPR and low peritonitis rate (LPR) group for all-cause mortality. However, when the peritonitis rate was considered as a continuous variable, a positive correlation was observed between the peritonitis rate and mortality. We found the quick peritonitis occurrence after CAPD and the low serum albumin level before CAPD were strongly associated with an HPR. Also, our results verified that HPR was positively correlated with technique failure. More importantly, the increase in the peritonitis rate suggested a higher risk of all-cause mortality. These results may help to identify and target patients who are at higher risk of HPR at the start

Ultrafiltration failure is a major complication of long-term peritoneal dialysis, resulting in dialysis failure. Peritoneal fibrosis induced by continuous exposure to high glucose dialysate is the major contributor of ultrafiltration failure, for which there is no effective treatment. Overactivation of several signaling pathways, including transforming growth factor-β1 (TGF-β1) and platelet-derived growth factor (PDGF) pathways, contribute to the development of peritoneal fibrosis. Therefore, simultaneously blocking multiple signaling pathways might be a potential novel method of treating peritoneal fibrosis. Previously, we showed that core fucosylation, an important posttranslational modification of the TGF-β1 receptors, can regulate the activation of TGF-β1 signaling in renal interstitial fibrosis. However, it remains unclear whether core fucosylation affects the progression of peritoneal fibrosis. Herein, we show that core fucosylation was enriched in the peritoneal membrane of rats accompanied by peritoneal fibrosis induced by a high glucose dialysate. Blocking core fucosylation dramatically attenuated peritoneal fibrosis in the rat model achieved by simultaneously inactivating the TGF-β1 and PDGF signaling pathways. Next the protective effects of blocking core fucosylation and imatinib (a selective PDGF receptor inhibitor) on peritoneal fibrosis were compared and found to exhibit a greater inhibitory effect over imatinib alone, suggesting that blocking activation of multiple signaling pathways may have superior inhibitory effects on the development of peritoneal fibrosis. Thus, core fucosylation is essential for the development of peritoneal fibrosis by regulating the activation of multiple signaling pathways. This may be a potential novel target for drug development to treat peritoneal fibrosis. Copyright © 2018 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

Even at the beginning of the new millennium, secondary peritonitis presents a common life-threatening condition associated with high mortality and morbidity. This article comments on epidemiology, diagnosis and general principles of surgical management in patients with secondary peritonitis. The demographic data, clinical findings and surgical outcome of 204 patients who had a confirmed generalized secondary peritonitis were analyzed retrospectively. Our approach was laparotomy, surgical control of contamination, antibiotic therapy and modern intensive care support. Acid peptic disease was the most common cause of perforation peritonitis 60 (29,41%), following by the perforated appendicitis 45 ( 22,06%). The faecal peritonitis and colon perforation were found in 42 patients (20,59%). The morbidity rate was 50%; 41 (40,2%) patients had more than one complication. The morbidity rate was significantly the highest in patients with colon perforation (n=38, 90%) (Hi-square=40,1; pcases (23,81%), and 4(6,6%) deaths due to gastro-duodenal perforation (Hi-square=45,7; pclinical presentation and outcome of the secondary peritonitis depend on duration of abdominal infection, the site of perforation and the general condition of the patient. Rapid surgical source control, modern intensive care and sepsis therapy may offer the chance of decreased morbidity and mortality of the intra-abdominal infections.

Peritoneal dialysis-associated peritonitis (PD-associated peritonitis) could influence the outcome of PD patients, including technique survival. Although the use of the twin-bag system has decreased the incidence of peritonitis, the effects of biocompatible PD solutions are controversial. Additionally, since both infection-causing microorganisms and antimicrobial therapies have changed over time, the duration of treatment of peritonitis (the duration of peritonitis) seems to have changed. The study included 527 patients who received PD between January 1980 and December 2012 at a single center. We divided patients undergoing PD into three groups according to the type of PD system used, namely single-bag and conventional PD solutions (S+C group, N = 145), twin-bag and conventional PD solutions (T+C group, N = 171) and twin-bag and biocompatible PD solutions (T+B group, N = 211), and analyzed PD-associated peritonitis incidences. Incidences of PD-associated peritonitis (times per patient-months) and peritonitis-free time were 1/59.4, 1/70.6 and 1/103.1, and 52, 97, and 100 months for the S+C, T+C and T+B groups, respectively. The duration of peritonitis, has thus, become dramatically shorter in recent years. Streptococcus sp. were associated with shortest and fungi with longest durations of peritonitis. Staphylococcus sp. and Pseudomonas aeruginosa were predominant in the S+C group. The twin-bag system has made a greater contribution to reductions in PD-associated peritonitis than biocompatible PD solutions. Furthermore, changes in microorganisms, antimicrobial therapies, patient education and improved PD system devices have presumably affected the reduction in the duration of peritonitis. © 2015 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

Lipman Jeffrey

2009-12-01

Full Text Available Abstract Background Antibiotics are preferentially delivered via the peritoneal route to treat peritonitis, a major complication of peritoneal dialysis (PD, so that maximal concentrations are delivered at the site of infection. However, drugs administered intraperitoneally can be absorbed into the systemic circulation. Drugs excreted by the kidneys accumulate in PD patients, increasing the risk of toxicity. The aim of this study is to examine a model of gentamicin pharmacokinetics and to develop an intraperitoneal drug dosing regime that maximises bacterial killing and minimises toxicity. Methods/Design This is an observational pharmacokinetic study of consecutive PD patients presenting to the Royal Brisbane and Women's Hospital with PD peritonitis and who meet the inclusion criteria. Participants will be allocated to either group 1, if anuric as defined by urine output less than 100 ml/day, or group 2: if non-anuric, as defined by urine output more than 100 ml/day. Recruitment will be limited to 15 participants in each group. Gentamicin dosing will be based on the present Royal Brisbane & Women's Hospital guidelines, which reflect the current International Society for Peritoneal Dialysis Peritonitis Treatment Recommendations. The primary endpoint is to describe the pharmacokinetics of gentamicin administered intraperitoneally in PD patients with peritonitis based on serial blood and dialysate drug levels. Discussion The study will develop improved dosing recommendations for intraperitoneally administered gentamicin in PD patients with peritonitis. This will guide clinicians and pharmacists in selecting the most appropriate dosing regime of intraperitoneal gentamicin to treat peritonitis. Trial Registration ACTRN12609000446268

♦ Background: The aim of the present study was to investigate the relationship between socio-economic status (SES) and peritoneal dialysis (PD)-related peritonitis. ♦ Methods: Associations between area SES and peritonitis risk and outcomes were examined in all non-indigenous patients who received PD in Australia between 1 October 2003 and 31 December 2010 (peritonitis outcomes). SES was assessed by deciles of postcode-based Australian Socio-Economic Indexes for Areas (SEIFA), including Index of Relative Socio-economic Disadvantage (IRSD), Index of Relative Socio-economic Advantage and Disadvantage (IRSAD), Index of Economic Resources (IER) and Index of Education and Occupation (IEO). ♦ Results: 7,417 patients were included in the present study. Mixed-effects Poisson regression demonstrated that incident rate ratios for peritonitis were generally lower in the higher SEIFA-based deciles compared with the reference (decile 1), although the reductions were only statistically significant in some deciles (IRSAD deciles 2 and 4 – 9; IRSD deciles 4 – 6; IER deciles 4 and 6; IEO deciles 3 and 6). Mixed-effects logistic regression showed that lower probabilities of hospitalization were predicted by relatively higher SES, and lower probabilities of peritonitis-associated death were predicted by less SES disadvantage status and greater access to economic resources. No association was observed between SES and the risks of peritonitis cure, catheter removal and permanent hemodialysis (HD) transfer. ♦ Conclusions: In Australia, where there is universal free healthcare, higher SES was associated with lower risks of peritonitis-associated hospitalization and death, and a lower risk of peritonitis in some categories.

Full Text Available Background: Endoglin is a specific angiogenic factor suspected to involve in the pathogenesis of endometriosis. The aim of this study was to evaluate the significance of endoglin concentration in the peritoneal fluid of patients with endometriosis.Methods: This pilot study was performed between March 2011 and July 2012 at Dr. Wahidin Sudirohusodo Hospital and another private hospital in Makassar, Indonesia. This was an observational, cross-sectional study. All patients undergoing laparoscopy for infertility and other cases with suitable inclusion criteria were asked to answer a questionnaire and had a 5 cc peritoneal fluid sample taken for measurement of peritoneal endoglin concentration using ELISA. Endometriosis stage was classified using ASRM criteria and divided into two groups, mild and severe. All data were analyed using Excel and Spearman correlation analysis.Results: In the endometriosis group peritoneal endoglin concentration ranged between 14.43- 15.65 ng/mL (median 15.04 ng/mL which is higher than control group 7.42-10.26 ng/mL (median 8.84 ng/mL. A peritoneal endoglin concentration equal to or higher than 11 ng/mL could be used to predict endometriosis.Conclusion: Endoglin concentrations increased proportionally with the severity of endometriosis, and many be used as predictive factor of endometriosis cases.

2015-01-01

Hydrothorax is a rare and often unrecognized complication associated with peritoneal dialysis (PD). This is usually due to the presence of pleuroperitoneal fistula. Most nephrologist will choose to cease the peritoneal dialysis and rest the peritoneum. More than often surgical interventions include pleurodesis or thoracotomy will be required. In this report, we reported a patient who developed pleural effusion after starting continuous ambulatory peritoneal dialysis. She was successfully managed by the use of low volume exchange during daytime with avoidance of conversion to haemodialysis or any surgical intervention. (author)

Fetal intestinal volvulus is a rare but serious finding with a high risk of potential life threatening fetal complications. Delay in diagnosis or treatment can increase mortality and morbidity. We report a case of mild fetal bowel dilatation at 30 weeks of gestation and intestinal volvulus presented by the 'whirl-sign', intestinal perforation and meconium peritonitis with fetal ascites and polyhydramnios at 33 weeks of gestation. This case emphasizes the role of examination of the bowel in third trimester ultrasound and the importance of quick decision to delivery and interdisciplinary perinatal management at suspected fetal volvulus with bowel necrosis and intraabdominal bleeding.

Effect of bile on growth, peritoneal absorption, and blood clearance of Escherichia coli in E coli peritonitis

International Nuclear Information System (INIS)

Andersson, R.; Schalen, C.; Tranberg, K.G.

1991-01-01

The effect of intraperitoneal bile on growth, peritoneal absorption, and clearance of Escherichia coli was determined in E coli peritonitis in the rat. In E coli peritonitis, intraperitoneal bacterial counts gradually decreased, whereas they increased (after 2 hours) with subsequent development of bacteremia in E coli plus bile peritonitis. After an intraperitoneal injection of labeled bacteria, blood radioactivity was only initially lower in E coli plus bile peritonitis compared with E coli peritonitis. Clearance from blood was lower in E coli plus bile peritonitis than in E coli peritonitis. Organ localization was similar in E coli peritonitis and E coli plus bile peritonitis with decreased splenic, increased pulmonary, and unchanged hepatic uptakes compared with controls. Impaired peritoneal absorption of bacteria, together with impaired local host defense, is likely to enhance the noxious effect of bile in E coli peritonitis

Full Text Available Peritoneal dialysis (PD using an ordinary stylet cannula was studied in 253 patients (67% male and 33% female with age ranging from 3-67 years suffering from renal failure. The study was conducted between January 2007 and December 2012. The procedure was well tolerated by the patients. The desired aims of dialysis including improvement in chemistry were achieved in all surviving (94.5% cases. Mortality during PD was 5.5% and was related to the underlying causes of renal failure. Peritonitis seen in 30% cases was the commonest complication. Other complications in order of frequency were, hypokalemia (8%, severe hyperglycemia in diabetic patients (6%, and sever hypovolemia (5%, pericatheter leak (5% and catheter blockage (2%. Perforation of the bowel, a serious complication occurring during insertion of the PD cannula was not seen in any of the cases. It is concluded from the study that PD is a simple and cost effective alternative to hemodialysis and have special advantages in the current set-up of the institute. The objective of our work was to study the results and complications of peritoneal dialysis in light of its efficacy as an alternative form of renal replacement therapy (RRT to hemodialysis.

2017-06-01

Paecilomyces variotii (P. variotii) is an extremely rare cause of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. When diagnosed, it usually portends poor prognosis. Patient's survival depends on early laboratory diagnosis and proper treatment. We herein report a P. variotii peritonitis in a patient on CAPD which is a quite rare clinical entity. Laboratory diagnosis was confirmed via both morphological analysis and DNA sequencing. Antifungal susceptibility tests were performed and interpreted according to the Clinical Laboratory Standards Institute M38-A2 guidelines. After laboratory diagnosis, the patient was treated succesfully with liposomal amphotericin B and itraconazole combination and the peritoneal catheter was removed. This case is worthy of reporting since P. variotii is an uncommon cause of peritonitis and leads to dilemmas in both laboratory diagnosis and treatment strategies.

The peritoneal cavity is a complex anatomical structure with multiple attachments and connections. These are better understood with reference to the embryological development of this region. Armed with this knowledge, the diagnosis and assessment of a wide range of common intra-abdominal diseases becomes straightforward. This article will review and simplify the terminology, complex embryological development, and anatomy of the peritoneum, peritoneal attachments, and the reflections forming the peritoneal boundaries. Normal anatomy will be described using schematic diagrams with corresponding computed tomography (CT) and magnetic resonance imaging (MRI) images, including CT peritoneograms. The relevance of intra- and extra-peritoneal anatomy to common pathological processes will be demonstrated

Enzyme matrix metalloproteinase-9 is a member of the matrix metalloproteinase family, which is critical to normal tissue remodelling during embryogenesis and wound healing. In patients with endometriosis, increased expression and activity of matrix metalloproteinase-9 have been observed in ectopic endometrium, but the plasma and peritoneal fluid concentrations of matrix metalloproteinase-9 in patients with endometriosis and their relation to disease severity have not been clear. The aim of the study was to investigate the concentrations of matrix metalloproteinase-9 in plasma and peritoneal fluid of patients with endometriosis. A prospective case-control study was conducted in Jinan Military General Hospital between January 2010 and December 2013. Fifty patients with proven endometriosis and 26 endometriosis-free controls were enrolled in this study. Patients with endometriosis were evaluated and divided into moderate/severe endometriosis group (stage I-II, n = 26) and minimal/mild endometriosis group (stage III-IV, n = 24) according to the revised criteria of the American Society for Reproductive Medicine. Blood samples and peritoneal fluid were obtained from both patients and controls. Matrix metalloproteinase-9 was measured using enzyme-linked immunosorbent assay in plasma and peritoneal fluid. The concentration of matrix metalloproteinase-9 between different groups was compared and its correlation to disease severity was analysed. Plasma and peritoneal fluid concentrations of matrix metalloproteinase-9 in patients with endometriosis were higher than that in controls. In addition, those patients with moderate/severe endometriosis had significantly higher plasma and peritoneal fluid concentrations of matrix metalloproteinase-9 compared to those with minimal/mild endometriosis. Matrix metalloproteinase-9 concentrations in plasma and peritoneal fluid were both positively correlated with severity of endometriosis and plasma matrix metalloproteinase-9

Improved Outcome of Enteric Peritonitis in Peritoneal Dialysis Patients Aged 50 Years and Older with Temporary Discontinuation of Peritoneal Dialysis and Intravenous Meropenem.

♦ BACKGROUND: Peritonitis is a major cause of morbidity, mortality, and technique failure in peritoneal dialysis (PD) patients, especially when caused by enteric microorganisms (EM). We have implemented a treatment protocol specifically aimed at improving the outcome in EM peritonitis. The adapted protocol was applied in all PD patients 50 years and older presenting with peritonitis who were considered to be at risk of EM peritonitis and involves 3 interventions: 1) temporary discontinuation of PD without removing the catheter (peritoneal rest), 2) intravenous meropenem, and 3) meropenem intracatheter as lock (Mero-PerRest protocol). ♦ METHODS: In this observational study, we compared the outcome of 203 peritonitis episodes in 71 patients treated with the Mero-PerRest protocol, with 217 episodes in 104 patients treated with a more traditional intraperitoneal gentamicin-rifampicin-based regimen. ♦ RESULTS: In EM peritonitis episodes, the Mero-PerRest protocol resulted in a higher primary cure rate (90.0% vs 65.3%, adjusted odds ratio [OR] 4.54 [95% confidence interval (CI) 1.46 - 14.15]) and better technique survival (90.0% vs 69.4%, adjusted OR 3.41 [95% CI 1.07 - 10.87]). This effect was most distinct in patients with polymicrobial EM peritonitis (cure rate 87.5% vs 34.8%, p = 0.0003). Interestingly, primary cure rate (95.6% vs 84.7%, adjusted OR 3.92 [95% CI 1.37 - 11.19]) and technique survival (95.6% vs 85.6%, adjusted OR 3.60 [95% CI 1.25 - 10.32]) were also excellent in non-EM peritonitis episodes. Patient survival did not differ significantly. ♦ CONCLUSION: The poor outcome of peritonitis caused by EM in PD patients aged 50 years and older could be improved by applying a treatment protocol involving temporary discontinuation of PD without catheter removal and intravenous and intracatheter meropenem.

Full Text Available The objective of the study was to identify the microbiological spectrum and drug-sensitivity pattern of peritonitis in patients on continuous ambulatory peritoneal dialysis. This was a prospective study done over a period of a year-and-a-half at a tertiary-care hospital in a hilly state of India. The effluent dialysate bags from 36 consecutive patients with peritonitis were studied. One hunderd ml dialysate fluid was processed under aseptic conditions by lysis centrifugation method. Microscopy and culture was done from the deposits for bacteriological, fungal, and mycobacterial isolates. They were identified by colony morphology and their biochemical reactions. Drug susceptibility testing was done by Kirby-Bauer disc diffusion method. In 36 dialysates, 33 (91.6% dialysates were culture-positive and in 3 (8.4%, the culture was negative. A total of 36 microorganisms were isolated in 33 cultures. Among the 36 microorganisms, 19 (52.8% isolates were gram-positive, 10 (27.8% were gram-negative, 5 (13.9% were fungi, and 2 (5.6% were mycobacterial isolates. All gram-positive organisms were sensitive to ampicillin, amoxi-clavulanic acid, cefazolin, clindamycin, and vancomycin. Neither a methicillin-resistant Staphylococci aureus nor a vancomycin-resistant Enterococcus was isolated in gram-positive isolates. Gram-negative organisms were sensitive to ciprofloxacin, ceftriaxone, ceftazidime, cefepime, gentamicin, piperacillin-tazobactam and imipenem. One of the gram-negative isolate was an extended spectrum beta-lactamase producer. Gram-positive peritonitis was more frequent than gram-negative peritonitis in our continuous ambulatory peritoneal dialysis patients. Mycobacterial causes were responsible for peritonitis in patients with culture-negative peritonitis which was not responding to the conventional antimicrobial therapy.

Purpose: We aimed to describe computed tomography (CT) findings in patients with peritoneal, omental and mesenteric lymphoma involvement. Materials and methods: We searched our archive retrospectively to find out patients with peritoneal, omental and mesenteric lymphoma involvement. We found 16 patients with non-hodgkin lymphoma meeting these criteria. CT studies of these patients were reevaluated for the presence of peritoneal involvement, ascites, omental mass, organomegaly, retroperitoneal lymphadenopathy, bowel wall thickening and other associated findings. Results: There were 14 males and 2 females with peritoneal and/or mesenteric and omental lymphoma involvement. Mean age was 39 (range 4-76). Subgroups of non-hodgkin lymphoma were diffuse large B-cell lymphoma (n = 11), small cell lymphocytic lymphoma (n = 2), small cleaved cell lymphoma (n = 1), T-cell lymphoma (n = 1) and Burkitt's lymphoma (n = 1). Peritoneal involvement was seen in 15 patients (93.8%) in the form of linear (n = 12) and nodular (n = 3) thickening. Ascites was seen in 12 (75%) patients. Omental and mesenteric masses were present in 10 (66.6%) and 10 (66.6%) patients, respectively. Bowel wall thickening, retroperitoneal lymphadenopathy and hepatosplenomegaly were also common and observed in 10, 10 and 11 patients, respectively. Solid organ involvement in the form of liver and splenic lesions was seen in 9 (56%) patients. Conclusion: Peritoneal involvement can be seen in many subtypes of lymphoma and most frequently in diffuse large B-cell lymphoma. Peritoneal lymphomatosis can mimic peritoneal carcinomatosis and should be included in the differential diagnosis list in patients with ascites, hepatosplenic lesions and unidentified cause of peritoneal thickening on CT in a male patient.

Surgical treatment of secondary peritonitis : A continuing problem.

van Ruler, O; Boermeester, M A

2017-01-01

Secondary peritonitis remains associated with high mortality and morbidity rates. Treatment of secondary peritonitis is challenging even in modern medicine. Surgical intervention for source control remains the cornerstone of treatment, beside adequate antimicrobial therapy and resuscitation. A randomized clinical trial showed that relaparotomy on demand (ROD) after initial emergency surgery is the preferred treatment strategy, irrespective of the severity and extent of peritonitis. The effective and safe use of ROD requires intensive monitoring of the patient in a setting where diagnostic tests and decision making about relaparotomy are guaranteed round the clock. The lack of knowledge on timely and adequate patient selection, together with the lack of use of easy but reliable monitoring tools, seems to hamper full implementation of ROD. The accuracy of the relap decision tool is reasonable for prediction of ongoing peritonitis and selection for computer tomography (CT). The value of CT in an early postoperative phase is unclear. Future research and innovative technologies should focus on the additive value of CT in cases of operated secondary peritonitis and on the further optimization of bedside prediction tools to enhance adequate patient selection for intervention in a multidisciplinary setting.

Spontaneous peritonitis, especially spontaneous fungal peritonitis (SFP), is an important and potentially fatal complication in patients with endstage liver disaese. We evaluated potential risk factors, microbiological findings, and outcome of patients with SFP compared to spontaneous bacterial peritonitis (SBP) in critically ill patients. Retrospective analyses of critically ill patients with suspected spontaneous peritonitis. Out of 205 patients, 20 (10%) had SFP, 28 (14%) had SBP, 48 (24%) had peritonitis without microbiological findings (SP) and 109 (52%) had no-peritonitis (NP). APACHE II and SOFA score were significantly higher in patients with SFP (26; 22-28; pperitonitis could be significantly more often found in patients with SFP (65%; pperitonitis was significantly more often in patients with SFP (85%; pperitonitis.

Full Text Available Abstract Background There has not been a comprehensive, multi-centre study of streptococcal peritonitis in patients on peritoneal dialysis (PD to date. Methods The predictors, treatment and clinical outcomes of streptococcal peritonitis were examined by binary logistic regression and multilevel, multivariate poisson regression in all Australian PD patients involving 66 centres between 2003 and 2006. Results Two hundred and eighty-seven episodes of streptococcal peritonitis (4.6% of all peritonitis episodes occurred in 256 individuals. Its occurrence was independently predicted by Aboriginal or Torres Strait Islander racial origin. Compared with other organisms, streptococcal peritonitis was associated with significantly lower risks of relapse (3% vs 15%, catheter removal (10% vs 23% and permanent haemodialysis transfer (9% vs 18%, as well as a shorter duration of hospitalisation (5 vs 6 days. Overall, 249 (87% patients were successfully treated with antibiotics without experiencing relapse, catheter removal or death. The majority of streptococcal peritonitis episodes were treated with either intraperitoneal vancomycin (most common or first-generation cephalosporins for a median period of 13 days (interquartile range 8–18 days. Initial empiric antibiotic choice did not influence outcomes. Conclusion Streptococcal peritonitis is a not infrequent complication of PD, which is more common in indigenous patients. When treated with either first-generation cephalosporins or vancomycin for a period of 2 weeks, streptococcal peritonitis is associated with lower risks of relapse, catheter removal and permanent haemodialysis transfer than other forms of PD-associated peritonitis.

Full Text Available Early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. We present a series of cases in which bedside ultrasound (US in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty free fluid consistent with a surgical final diagnosis of a perforated hollow viscus. In all patients with suspected perforated viscus, clinicians were able to accurately identify the signs of pneumoperitoneum including enhanced peritoneal stripe sign (EPSS, peritoneal stripe reverberations, and focal air collections associated with dirty shadowing or distal multiple reflections as ring down artifacts. In all cases, hollow viscus perforation was confirmed surgically. It seems that, performing US in patients with suspected perforated viscus can accurately identify presence of intra-peritoneal echogenic or “dirty” free fluid as well as evidence of free air, and may expedite patient management.

Postoperative peritoneal adhesions continue to be a major source of morbidity and occasional mortality. Studies have shown that matrix metalloproteinase-9 (MMP-9) levels are decreased postoperatively which may limits matrix degradation and participate in the development of peritoneal adhesions. In this proof-of-principle study, we evaluated the effect of gene therapy with catalytically inactive mutant MMP-9 on postoperative peritoneal adhesions in rats. Adenovirus encoding mutant MMP-9 (Ad-mMMP-9) or saline was instilled in the peritoneal cavity after cecal and parietal peritoneal injury in rats. Expression of mutant MMP-9 transcript was verified by sequencing. Adenovirus E4 gene expression, adhesion scores, MMP-9, tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1) and transforming growth factor-β1 (TGF-β1) expression were evaluated at sacrifice one week after treatment. Both mutant MMP-9 transcripts and adenovirus E4 gene were expressed in Ad-mMMP-9 treated adhesions. Adhesions severity decreased significantly (p = 0.036) in the Ad-mMMP-9-treated compared with saline-treated adhesions. Expression of MMP-9 mRNA and protein were elevated (p = 0.001 and p = 0.029, respectively) in the Ad-mMMP-9-treated adhesions compared with saline-treated adhesions. While tPA levels were increased (p = 0.02) in Ad-mMMP-9 treated adhesions compared with saline-treated adhesions, TGF-β1 and PAI-1 levels were decreased (p = 0.017 and p = 0.042, respectively). No difference in mortality were found between groups (p = 0.64). Mutant MMP-9 gene therapy effectively transduced peritoneal adhesions resulting in reduction of severity of primary peritoneal adhesions. Copyright © 2016 IJS Publishing Group Limited.

To describe the clinical characteristics of recurrent septic peritonitis in dogs. Multicenter retrospective observational study. Client-owned dogs with recurrent septic peritonitis. Three university emergency and referral hospitals. None. Medical records from 3 veterinary university teaching hospitals were reviewed and data were collected using a standardized data collection sheet for all cases of septic peritonitis during the study period (2000-2011). Forty one dogs met the inclusion criteria for recurrent peritonitis. All dogs underwent relaparotomy. The original cause of septic peritonitis in these cases included previous surgery for gastrointestinal foreign body removal (n = 26), gastrointestinal neoplasia (n = 3), gastric or duodenal ulceration (n = 3), biliary tract leakage (n = 2), and single instance for each of the following: penetrating foreign body, hernia strangulation, intussusception, mesenteric volvulus, infection of the laparotomy incision, prostatic abscess, and trauma. Eighteen animals survived to discharge. There was no difference detected between survivors and nonsurvivors with recurrent peritonitis in terms of inciting cause, serum albumin concentration, surgical management, or provision of appropriate initial antimicrobials. The survival rate for dogs having recurrent peritonitis was 43.9% (18/41 dogs). This retrospective study did not identify any significant prognostic indicators for dogs with recurrent peritonitis and that the mortality rate for dogs having more than one surgery for septic peritonitis is similar to that reported for a single surgery for septic peritonitis. ©Veterinary Emergency and Critical Care Society 2015.

.2%) such as pneumonia, peritonitis, catheter tunnel infection, exit site infection and cardiac related complications (37.4%) such as congestive cardiac failure, acute coronary syndrome, pericarditis/pericardial effusion were the most frequently encountered complications. Forty-one per cent of patients were transferred to haemodialysis mainly on account of inadequate dialysis clearance. Sepsis (42%) such as pneumonia, urinary tract infection, peritonitis and cardiac related causes (31%) such as congestive cardiac failure and acute coronary syndrome were the two major causes of death. Of those who died of sepsis, 45.2% had pneumonia. Only 9.5% (4/42) of patients had confirmed peritonitis during their illness. Infection and cardiovascular disease were common complications observed in this study. Therefore intensive management of risk factors (hypertension, diabetes and dyslipidaemia) and prompt recognition of infection is hereby recommended. Early recognition and appropriate management of sepsis in peritoneal dialysis patients should be initially based on standard protocol. The use of erythropoietin in peritoneal dialysis patients will enhance better management of anaemia and improve quality of life.

Sclerosing encapsulating peritonitis is a well recognized, but uncommon, complication of chronic ambulatory peritoneal dialysis. I report a case of sclerosing encapsulating peritonitis in which percutaneous catheter drainage was performed preoperatively. Ultrasonography(US) and computed tomography(CT) showed a large multi-septated cystic mass which occupied nearly all the peritoneal cavity. Percutaneous drainage with two 8.5 French catheters was preoperatively performed under fluoroscopy and about 2100 ml of bloody fluid was drained for 20 days. On follow-up CT, the size of the cyst had significantly decreased and anoperation was performed. It is considered that percutaneous catheter drainage is useful in the preoperative decompression of sclerosing encapsulating peritonitis.

Peritoneal mesothelioma

1985-01-01

The definitive diagnosis of peritoneal mesothelioma and its differentiation from metastatic peritoneal carcinomatosis may be difficult because of the clinical, macroscopic, and microscopic variability of the tumor. To this purpose, a combination of criteria, including the clinical picture, the gross pathologic findings, the exclusion of other primary neoplasms, and the microscopic findings, must be taken into consideration. Conventionally, these criteria may be established only after surgical exploration and extensive sampling. Experience with patients with peritoneal mesothelioma and metastatic peritoneal carcinomatosis, as well as a review of the recent imaging literature, shows excellent correlation between computed tomography or ultrasound and the operative or autopsy findings. These imaging modalities showed soft-tissue masses or nodules; thickened omentum (omental cake), peritoneum, mesentery, and bowel wall; pleural plaques; and usually disproportionally small, if any, ascites. The latter two observations may be useful in differentiating mesothelioma from carcinomatosis macroscopically. Furthermore, fine-needle aspiration biopsy, after performing wide sampling of the tumors in different locations under ultrasonic or computed tomographic guidance, produced diagnostic cytologic specimens. Thus, the need for exploratory surgery may be alleviated, and the diagnosis of peritoneal mesothelioma may be made prospectively and relatively noninvasively with the use of computed tomography or ultrasound and fine-needle aspiration biopsy. Since epidemiologic studies predict increasing incidence of this neoplasm, especially among asbestos workers, it is suggested that these techniques be seriously considered as screening methods for high-risk populations.67 references

The peritoneal mesothelioma is a rare neoplasm which arises from the peritoneal lining of the abdomen, tending to spread along the peritoneal cavity and to invade abdominal organs. Authors report the CT findings of 4 patients with histologically proven peritoneal mesothelioma seen at Dongsan Medical Center, School of Medicine, Keimyung University. None of them had a history of exposure to asbestos and no clear etiologic factor could be determined in any patient. CT showed peritoneal and mesenteric thickenings in all cases, omental thickenings in 3 cases, peritoneal nodules, mesenteric masses or omental masses in 2 cases each other, bowel wall involvement in 1 case, and disproportionally small ascites in 2 cases. Distant hematogenous metastases to the liver and retroperitoneal lymph nodes were seen in 1 case. Our experience with 4 peritoneal mesotheliomas as well as a review of the recent imaging literature shows excellent correlation between computed tomography and the operitoneoscopic findings

Peritoneal dialysis peritonitis and fluid overhydration (OH) are frequent problems in peritoneal dialysis. The latter can cause gut wall oedema or be associated with malnutrition. Both may lead to increased peritonitis risk. We wished to determine if OH is an independent risk factor for peritonitis (caused by enteric organisms). Retrospectively study of patients with >2 bioimpedance assessments (Body Composition Monitor). We compared peritonitis rates of patients with above or below the median time-averaged hydration parameter (OH/extracellular water, OH/ECW). Multivariate analysis was performed to determine independent risk factors for peritonitis by enteric organism. We studied 580 patients. Peritonitis was experienced by 28% patients (followed up for an average of 17 months). The overall peritonitis rate was 1:34 patient months. Patients with low OH/ECW values had significantly lower rates of peritonitis from enteric organisms than overhydrated patients (incident rate ratio 1.53, 95% confidence interval 1.38-1.70, P peritonitis from enteric organisms when multivariate model included demographic parameters (odds ratio for a 1% increment of OH/ECW was 1.05; 95% confidence interval 1.01-1.10, P peritonitis. While this may partly be due to the high co-morbidity of patients (advanced age and diabetes), on multivariate analysis, only inclusion of nutritional parameters reduced this association. It remains to be determined if overhydration will prove to be a modifiable risk factor for peritonitis or whether malnutrition will prove to be more important. © 2015 Asian Pacific Society of Nephrology.

Intraperitoneal administration of antibiotics is recommended as a first treatment for managing peritoneal dialysis (PD)-related peritonitis. However, the efficacy of oral administration of quinolones has not been well studied. Randomized controlled pilot study. 80 eligible patients with PD-related peritonitis from Peking University First Hospital (40 in each arm). Intraperitoneal vancomycin, 1g, every 5 days plus oral moxifloxacin, 400mg, every day (treatment group) versus intraperitoneal vancomycin, 1g, every 5 days plus intraperitoneal ceftazidime, 1g, every day (control group). The primary end point was complete resolution of peritonitis, and secondary end points were primary or secondary treatment failure. PD effluent white blood cell count. Baseline demographic and clinical characteristics of the 2 groups were comparable. There were 24 and 22 Gram-positive organisms, 6 and 7 Gram-negative organisms, 9 and 10 culture-negative samples, and 1 and 1 fungal sample in the treatment and control groups, respectively. Complete resolution of peritonitis was achieved in 78% and 80% of cases in the treatment and control groups, respectively (OR, 0.86; 95% CI, 0.30-2.52; P=0.8). There were 3 and 1 cases of relapse in the treatment and control groups, respectively. Primary and secondary treatment failure rates were not significantly different (33% vs 20% and 10% vs 13%, respectively). In each group, there was 1 peritonitis-related death and 6 transfers to hemodialysis therapy. During the 3-month follow-up period, 7 and 3 successive episodes of peritonitis occurred in the treatment and control groups, respectively. Only 2 adverse drug reactions (mild nausea and mild rash, respectively) were observed in the 2 groups. Sample size was relatively small and the eligibility ratio was low. Also, the number of peritonitis episodes was low, limiting the power to detect a difference between groups. This pilot study suggests that intraperitoneal vancomycin with oral moxifloxacin is a

Peritoneal carcinomatosis can be difficult to diagnose using computed tomography (CT). The purpose of this study was to evaluate the role of 2-(fluorine 18) fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET) in the detection of peritoneal carcinomatosis. We reviewed the CT and FDG PET radiological reports and clinical charts of 18 patients with peritoneal carcinomatosis and 17 cancer patients without peritoneal carcinomatosis. We also assessed FDG PET scans from 20 healthy volunteers as a baseline study. The maximum standardised uptake values (SUV max ) over peritoneal lesions in cancer patients and over the area of most intense intestinal uptake in healthy volunteers and cancer patients without peritoneal carcinomatosis were measured. The sensitivity and positive predictive value (PPV) of combined FDG PET and CT were superior to those of CT alone for the detection of peritoneal lesions (sensitivity: 66.7% vs 22.2%, p max threshold of 5.1 produced a diagnostic accuracy of combined FDG PET and CT of 78%. The additional information provided by FDG PET allowed a more accurate diagnosis in 14 patients (40.0%), and led to alteration of the therapeutic strategy in five (14.3%) of the enrolled cancer patients. We found that use of an intra-abdominal FDG uptake cut-off value for SUV max of >5.1 assists in the diagnosis of peritoneal carcinomatosis. FDG PET may play an important role in the clinical management of patients with suspected peritoneal carcinomatosis. (orig.)

Peritoneal tumour dissemination is still considered as a terminal disease. For the last two decades, cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy (HIPEC) has been popularised by Paul Sugarbaker almost doubling survival in selected patients compared with systemic chemotherapy alone. Nowadays, this particular treatment protocol is available in comprehensive cancer centres with reasonable mortality and morbidity. However, patient selection is still challenging. In general, CRS and HIPEC is indicated in primary peritoneal tumours such as mesothelioma and pseudomyxoma peritonei as well as in peritoneal metastases derived from gastrointestinal malignancies and ovarian cancers. Since systemic tumour spread is uncommon in patients with peritoneal metastases, peritoneal tumour dissemination was defined as localised disease within the "compartment abdomen". However, CRS and HIPEC are only beneficial as long as complete cytoreduction is achieved (CC-0 or CC-1). Histopathological parameters, the Sugarbaker peritoneal carcinomatosis index (PCI) and general condition of the patient have been established as patient selection criteria. In primary peritoneal cancers, individual tumour biology is the predominant criterium for patient selection as opposed to intraabdominal tumour load in peritoneal metastases derived from gastrointestinal cancers. In gastric cancer, CRS and HIPEC should be restricted to synchronous limited disease because of its biological aggressiveness. In patients with free floating cancer cells without macroscopic signs of peritoneal spread, however, CRS and HIPEC following preoperative "neoadjuvant" chemotherapy preserves chances for cure. So far, there is no general recommendation for CRS and HIPEC by clinical practice guidelines. In the recent S3 guideline for treatment of colorectal cancer, however, CRS and HIPEC have been included as possible treatment options. Georg Thieme Verlag KG Stuttgart · New York.

The purpose of the study was to evaluate the non-infectious complications of continuous ambulatory peritoneal dialysis (CAPD) using peritoneal computed tomography (PCT). Twenty symptomatic patients were included in the study. Initially 2000 ml of dialysate fluid was infused into the peritoneal cavity and standard peritoneal computed cavity and standard peritoneal computed tomography (SPCT) serial scans with 10 mm thickness were performed from the mid-thoracic region to the genital organs. Afterwards, 100 ml of non-ionic contrast material containing 300 mg/ml iodine was injected through the catheter and was distributed homogeneously in the intra-abdominal dialysate fluid by changing the positions of the patients; after waiting for 2-4 h, the CT scan was repeated as peritoneal contrast computed tomography (PCCT). In patients (n = 20) both SPCT and PCCT revealed 90 % (n = 18) pathological findings. But PCCT showed 60 % (n = 12) additional pathological findings. We believe that PCT is beneficial for evaluation of non-infectious complications of CAPD. But PCCT is superior to SPCT in evaluating non-infectious complications encountered in patients on CAPD treatment. (author)

Serum 25-Hydroxyvitamin D Level Could Predict the Risk for Peritoneal Dialysis-Associated Peritonitis.

♦ As an immune system regulator, vitamin D is commonly deficient among patients on peritoneal dialysis (PD), which may contribute to their impaired immune function and increased risk for PD-related peritonitis. In this study, we aimed to investigate whether vitamin D deficiency could predict the risk of peritonitis in a prospective cohort of patients on PD. ♦ We collected 346 prevalent and incident PD patients from 2 hospitals. Baseline demographic data and clinical characteristics were recorded. Serum 25-hydroxyvitamin D (25[OH]D) was measured at baseline and prior to peritonitis. The mean doses of oral active vitamin D used during the study period were also recorded. The outcome was the occurrence of peritonitis. ♦ The mean age of patients and duration of PD were 58.95 ± 13.67 years and 28.45 (15.04 - 53.37) months, respectively. Baseline 25(OH)D level was 16.15 (12.13 - 21.16) nmol/L, which was closely associated with diabetic status, longer PD duration, malnutrition, and inflammation. Baseline serum 25(OH)D predicted the occurrence of peritonitis independently of active vitamin D supplementation with a hazard ratio (HR) of 0.94 (95% confidence interval [CI] 0.90 - 0.98) after adjusting for recognized confounders (age, gender, dialysis duration, diabetes, albumin, residual renal function, and history of peritonitis). Compared to the low tertile, middle and high 25(OH)D level tertiles were associated with a decreased risk for peritonitis with HRs of 0.54 (95% CI 0.31 - 0.94) and 0.39 (95% CI 0.20 - 0.75), respectively. ♦ Vitamin D deficiency evaluated by serum 25(OH)D rather than active vitamin D supplementation is closely associated with a higher risk of peritonitis.

Peritoneal adhesions after laparoscopic gastrointestinal surgery.

Science.gov (United States)

Mais, Valerio

2014-05-07

Although laparoscopy has the potential to reduce peritoneal trauma and post-operative peritoneal adhesion formation, only one randomized controlled trial and a few comparative retrospective clinical studies have addressed this issue. Laparoscopy reduces de novo adhesion formation but has no efficacy in reducing adhesion reformation after adhesiolysis. Moreover, several studies have suggested that the reduction of de novo post-operative adhesions does not seem to have a significant clinical impact. Experimental data in animal models have suggested that CO₂ pneumoperitoneum can cause acute peritoneal inflammation during laparoscopy depending on the insufflation pressure and the surgery duration. Broad peritoneal cavity protection by the insufflation of a low-temperature humidified gas mixture of CO₂, N₂O and O₂ seems to represent the best approach for reducing peritoneal inflammation due to pneumoperitoneum. However, these experimental data have not had a significant impact on the modification of laparoscopic instrumentation. In contrast, surgeons should train themselves to perform laparoscopy quickly, and they should complete their learning curves before testing chemical anti-adhesive agents and anti-adhesion barriers. Chemical anti-adhesive agents have the potential to exert broad peritoneal cavity protection against adhesion formation, but when these agents are used alone, the concentrations needed to prevent adhesions are too high and could cause major post-operative side effects. Anti-adhesion barriers have been used mainly in open surgery, but some clinical data from laparoscopic surgeries are already available. Sprays, gels, and fluid barriers are easier to apply in laparoscopic surgery than solid barriers. Results have been encouraging with solid barriers, spray barriers, and gel barriers, but they have been ambiguous with fluid barriers. Moreover, when barriers have been used alone, the maximum protection against adhesion formation has been no

Chronic inflammation of the peritoneum causes peritoneal injury in patients on peritoneal dialysis. Intercellular adhesion molecule-1 and its circulating form, soluble intercellular adhesion molecule-1, play pivotal roles in inflammation. However, their role in peritoneal injury is unclear. We measured changes in intercellular adhesion molecule-1 expression in the peritoneum of a peritoneal injury model in rats. The associations between soluble intercellular adhesion molecule-1 levels in drained dialysate and the solute transport rate (D/P-Cr and D/D0-glucose) determined by the peritoneal equilibration test, and matrix metalloproteinase-2 levels in drained dialysate were investigated in 94 peritoneal drained dialysate samples. Intercellular adhesion molecule-1 expression was increased in the peritoneum of rats with peritoneal injury. Soluble intercellular adhesion molecule-1 levels in drained dialysate were significantly positively correlated with D/P-Cr (r = .51, p molecule-1expression is increased in the peritoneum of a peritoneal injury model in the rat, and soluble intercellular adhesion molecule-1 levels in drained dialysate are associated with peritoneal injury in patients on peritoneal dialysis. These results suggest that soluble intercellular adhesion molecule-1 could be a novel biomarker of peritoneal injury in patients on peritoneal dialysis.

Full Text Available Peritoneal equilibration test (PET is an important tool for managing peritoneal dialysis (PD prescription. The Kidney Disease Outcomes Quality Initiative (KDOQI guidelines suggest that the first PET be performed 4-8 weeks after PD commencement. The main reason for this delay is because of the peritoneal membrane might change its character once it is exposed to the glucose based dialysate. In this study, we compared PET 2 weeks after PD commencement to PET after 6 months to evaluate the changes in the peritoneal membrane character with time. This study included 126 patients who underwent PD initiation between March 2007 and December 2011. The PET was performed as per the standard protocol at 2 nd week and 6 th month after PD initiation. Transport status was categorized as low, low average, high average, and high as per the standard definition. There was no change in transport character in 115 patients (91.2% between the two PET measurements. When the Early PET at 2 nd week and 6 th month PET data were analyzed, no significant changes were observed in measured D/P creatinine (0.59 ± 0.14 vs. 0.62 ± 0.14 respectively P = 0.26 and D/D0 Glucose (0.46 ± 0.12 vs. 0.46 ± 0.11, P = 0.65. Using the Bland-Altman analysis the repeatability coefficients were 0.27 and 0.25 for creatinine and glucose values respectively. In our study, the PET performed at the 2 nd week are similar to that of the 6 th month PET in 91.2% of our patients and the test did not significantly change with time. In conclusion, we could do PET early at 2 nd week to assess the peritoneal membrane character and this would help in proper dialysis prescription to the patients.

Full Text Available Peritoneal fibrosis is a major complication in peritoneal dialysis (PD patients, which leads to dialysis discontinuation. Periostin, increased by transforming growth factor β1 (TGF-β1 stimulation, induces the expression of extracellular matrix (ECM genes. Aberrant periostin expression has been demonstrated to be associated with PD-related peritoneal fibrosis. Therefore, the effect of periostin inhibition by an aptamer-based inhibitor on peritoneal fibrosis was evaluated. In vitro, TGF-β1 treatment upregulated periostin, fibronectin, α-smooth muscle actin (α-SMA, and Snail expression and reduced E-cadherin expression in human peritoneal mesothelial cells (HPMCs. Periostin small interfering RNA (siRNA treatment ameliorated the TGF-β1-induced periostin, fibronectin, α-SMA, and Snail expression and restored E-cadherin expression in HPMCs. Similarly, the periostin-binding DNA aptamer (PA also attenuated fibronectin, α-SMA, and Snail upregulation and E-cadherin downregulation in TGF-β1-stimulated HPMCs. In mice treated with PD solution for 4 weeks, the expression of periostin, fibronectin, α-SMA, and Snail was significantly increased in the peritoneum, whereas E-cadherin expression was significantly decreased. The thickness of the submesothelial layer and the intensity of Masson’s trichrome staining in the PD group were significantly increased compared to the untreated group. These changes were significantly abrogated by the intraperitoneal administration of PA. These findings suggest that PA can be a potential therapeutic strategy for peritoneal fibrosis in PD patients.

CT findings in 137 patients with peritoneal cacinomatosis were reviewed to determine the CT signs of peritoneal malignancy. CT of the 20 liver cirrhosis and 17 tuberculous peritonitis were also reviewed to define the differential point between benign and malignant peritoneal change. The results were as follows. 1. The most common primary malignancy encountered in peritoneal carcinomatosis was stomach Ca.(50.4%), followed by pancreas Ca, hepatoma, colon Ca. and ovarian Ca. 2. Ascites was the most common CT feature of peritoneal malignancy, present in 99 cases (72.3%). The amount of ascites was voluminous, grade III in 70% of cases and showed high density ascites with average 23 Hounsfield units. 3. Greater omentum involvement was noted in 88 patients, peritoneum in 71 patients and mesentery in 65% patients. There was no correlation of the primary malignancy type with the incidence or pattern of the above mentioned site. 4. Bowel wall thickenings were observed in 51 patients, among which transverse colon was most frequently involved. 5. Mean attenuation value of ascites in liver cirrhosis was 10.7 HU, which was much lower than that of peritoneal carcinomatosis. 6. Even though intraperitoneal findings in Tbc. Peritonitis showed tendency of relatively small amount of ascites with more predominant mesenteric change, but, the findings of high density ascites, change of peritoneum and omentum etc. were very similar to those of peritoneal carcinomatosis. Therefore, based on only intraperitoneal change, differential diagnosis between them was difficult. 7. False negatives in CT diagnosis of peritoneal carcinomatosis occurred in 7 cases. There were tiny nodular changes in intraperitoneal cavity without ascites on operative findings

Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients' technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its effects on clinical outcomes in CAPD patients.This is a single center, retrospective, observational cohort study. A total of 294 patients who developing at least 1 episode of peritonitis were followed up from March 1st, 2002, to July 31, 2014, in our PD center. Multivariate logistic regression was used to determine the factors associated with HPR, and the Cox proportional hazard model was conducted to assess the effects of HPR on clinical outcomes.During the study period of 2917.5 patient-years, 489 episodes of peritonitis were recorded, and the total peritonitis rate was 0.168 episodes per patient-year. The multivariate analysis showed that factors associated with HPR include a quick occurrence of peritonitis after CAPD initiation (shorter than 12 months), and a low serum albumin level at the start of CAPD. In the Cox proportional hazard model, HPR was a significant predictor of technique failure. There were no differences between HPR and low peritonitis rate (LPR) group for all-cause mortality. However, when the peritonitis rate was considered as a continuous variable, a positive correlation was observed between the peritonitis rate and mortality.We found the quick peritonitis occurrence after CAPD and the low serum albumin level before CAPD were strongly associated with an HPR. Also, our results verified that HPR was positively correlated with technique failure. More importantly, the increase in the peritonitis rate suggested a higher risk of all-cause mortality.These results may help to identify and target patients who are at higher risk of HPR at the start of CAPD and to

Sequential peritoneal equilibration test (sPET) is based on the consecutive performance of the peritoneal equilibration test (PET, 4-hour, glucose 2.27%) and the mini-PET (1-hour, glucose 3.86%), and the estimation of peritoneal transport parameters with the 2-pore model. It enables the assessment of the functional transport barrier for fluid and small solutes. The objective of this study was to check whether the estimated model parameters can serve as better and earlier indicators of the changes in the peritoneal transport characteristics than directly measured transport indices that depend on several transport processes. 17 patients were examined using sPET twice with the interval of about 8 months (230 ± 60 days). There was no difference between the observational parameters measured in the 2 examinations. The indices for solute transport, but not net UF, were well correlated between the examinations. Among the estimated parameters, a significant decrease between the 2 examinations was found only for hydraulic permeability LpS, and osmotic conductance for glucose, whereas the other parameters remained unchanged. These fluid transport parameters did not correlate with D/P for creatinine, although the decrease in LpS values between the examinations was observed mostly for patients with low D/P for creatinine. We conclude that changes in fluid transport parameters, hydraulic permeability and osmotic conductance for glucose, as assessed by the pore model, may precede the changes in small solute transport. The systematic assessment of fluid transport status needs specific clinical and mathematical tools beside the standard PET tests.

Peritoneal metastasis is frequent mode of dissemination of intraabdominal malignancies. Radiologic diagnosis of peritoneal metastasis has relied on indirect evidence on a barium UGI series and small bowel examination. With the advent of CT scanning, CT is capable of direct imaging of peritoneum. The sensitivity of CT in detecting peritoneal metastasis and CT manifestation of peritoneal metastatic lesions had reported occasionally, but rarely in Korea. So, authors illustrated the CT manifestation of peritoneal metastatic lesions in 32 cases of macroscopically proven cases in laparoscopy or laparotomy in Korea University Hae Wha Hospital during recent 4 years. The results are as follows. 1. Of total 32 cases, 18 cases were male and 14 cases were female. Age incidence was the most common in 6th decade. 2. The most common type of malignancy that cause peritoneal metastasis was the stomach cancer and next common type of malignancies were pancreas cancer in men and ovarian cancer in women. 3. Of total 32 cases of peritoneal metastasis which was confirmed by laparoscopy or laparotomy macroscopically, 23 cases (72%) were detected peritoneal thickening and/or omental pathology by CT, and the remaining 9 cases (28%) were not detected by CT. 4. Ascites was present in 19 cases (59%). 5. Parietal peritoneal thickening was present in 16 cases (50%) by CT and sheetlike pattern was the most common findings. The patterns of peritoneal thickening was relatively nonspecific and was not correlated with primary tumor type. 6. Tumor involvement of greater omentum by CT was present in 19 cases (59%). There were 7 cases of smudged appearance pattern, 6 cases of nodular pattern, 6 cases of omental cake pattern and no cystic mass pattern. The patterns of omental pathology was relatively nonspecific and was nor correlated with primary tumor type

Full Text Available Peritonitis is a common and life-threatening complication of acute peritoneal dialysis (PD. Diagnosis requires the presence of clinical signs of peritonitis which are nonspecific and laboratory investigations [total leukocyte count (TLC, Gram-stain, and culture of PD effluent fluid] which are time-consuming and not available at the bedside. In this study, we evaluated the use of leukocyte esterase reagent strip (LERS as a bedside test to diagnose peritonitis in patients undergoing acute PD. Patients who underwent acute PD were monitored for signs and symptoms of peritonitis. PD effluent fluid analysis included TLC, absolute neutrophil count, Gram-stain, and culture for the diagnosis of peritonitis. LERS (Multistix 10SG was simultaneously dipped in PD effluent fluid and read at two minutes. Reading of + was considered as indicative of peritonitis. Twenty-one out of 166 (12.6% patients undergoing acute PD developed peritonitis. LERS detected peritonitis in 20 patients. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV of LERS were 95.2%, 95.2%, 74.1%, and 99.3%, respectively. LERS has very high sensitivity and NPV and can be used as a rapid bedside tool to exclude peritonitis in patients undergoing acute PD.

We identified differentially expressed genes comparing peritoneal endometriosis lesions (n = 18), eutopic endometrium (n = 17), and peritoneum (n = 22) from the same patients with complete menstrual cycles using microarrays (54 675 probe sets) and immunohistochemistry. Peritoneal lesions and peritoneum demonstrated 3901 and 4973 significantly differentially expressed genes compared to eutopic endometrium, respectively. Peritoneal lesions significantly revealed no correlation with a specific menstrual cycle phase by gene expression and histopathology, exhibited low expressed proliferation genes, and constant levels of steroid hormone receptor genes. Tissue remodeling genes in cytoskeleton, smooth muscle contraction, cellular adhesion, tight junctions, and O-glycan biosynthesis were the most significant to lesions, including desmin and smooth muscle myosin heavy chain 11. Protein expression and location of desmin, alpha-actin, and h-caldesmon in peritoneal lesions discriminated between smooth muscle hyperplasia and metaplasia. Peritoneal lesions demonstrate no menstrual cycle phasing but constant steroid hormone receptor expression where a slow but steady growth is linked with tissue remodeling. Our study contributes to the molecular pathology of peritoneal endometriosis and will help to identify clinical targets for treatment and management.

Seventy-three abdominopelvic CT studies in 60 patients with peritoneal tumor spread were reviewed. Ascites was the most common CT finding (74%), with loculation occurring in half. A new finding, loculation of fluid out of the cul-de-sac, is described. Parietal peritoneal thickening and enhancement was visible as a thin enhancing line along the peritoneal surface in 62% of studies. This represents the CT correlate of miliary seeding that has progressed to the point of confluence. Tumor involvement of the omentum was manifest as marbled fat, enhancing nodules, or an omental cake. Mucin-producing implants and their progression to pseydomyxoma peritonei were observed. In 26 patients without a known malignancy, a specific diagnosis was possible in 13 (50%) with identification of a primary tumor. Of 13 patients with no visible primary, six (46%) had ovarian peritoneal carcinomatosis with normal-sized ovaries or minimal adnexal pathology

Peritonitis is one of the major comorbidities of peritoneal dialysis (PD) patients. The aim of this study was to concentrate on potential risk factors, including more recently studied ones among the classical ones for peritonitis, in PD patients. We analysed 109 patients (F/M = 42/67) followed up at least for 3 months in a single centre, a tertiary referral hospital for 360.1 patient years. In the study which is designed as a retrospective cohort study, demographic characteristics, conditions for choosing PD, type of PD treatment, some chemical tests and peritonitis episodes were recorded from the files of the patients. The rate of peritonitis was found to be 0.22 episode/patient year and 22 (20.18%) of the patients had more than one episode. Twenty seven (24.8%) of the patients were allocated to PD due to obligatory reasons. According to multiple regression analysis, the associated factors were found to be PD allocation type (obligatory versus voluntary) (p = 0.04; RR = 2.6), serum albumin level (p = 0.05; RR = 1.2), and anti-hepatitis C Virus Antibody positivity (p = 0.03; RR = 1.6). Frequency of female patients were significantly higher in the group who had multiple episodes (p = 0.01). Obligatory referral which can be an indication of loss of motivation for peritoneal dialysis procedures, is thought to be a strong risk factor for peritonitis in PD patients and should be further studied. Patients with multiple episodes had a higher frequency of obligatory referral as expected and additionally, they were higher in number of females when compared to the ones with single episode.

Peritonitis is a leading cause of hospitalizations, morbidity, and modality change in pediatric chronic peritoneal dialysis (CPD) patients. Despite guidelines published by the International Society for Peritoneal Dialysis aimed at reducing the risk of peritonitis, registry data have revealed significant variability in peritonitis rates among centers caring for children on CPD, which suggests variability in practice. Improvement science methods have been used to reduce a variety of healthcare-associated infections and are also being applied successfully to decrease rates of peritonitis in children. A successful quality improvement program with the goal of decreasing peritonitis will not only include primary drivers directly linked to the outcome of peritonitis, but will also direct attention to secondary drivers that are important for the achievement of primary drivers, such as health literacy and patient and family engagement strategies. In this review, we describe a comprehensive improvement science model for the reduction of peritonitis in pediatric patients on CPD.

♦ Background: There is limited available evidence regarding the role of monitoring serum gentamicin concentrations in peritoneal dialysis (PD) patients receiving this antimicrobial agent in gram-negative PD-associated peritonitis. ♦ Methods: Using data collected in all patients receiving PD at a single center who experienced a gram-negative peritonitis episode between 1 January 2005 and 31 December 2011, we investigated the relationship between measured serum gentamicin levels on day 2 following initial empiric antibiotic therapy and subsequent clinical outcomes of confirmed gram-negative peritonitis. ♦ Results: Serum gentamicin levels were performed on day 2 in 51 (77%) of 66 first gram-negative peritonitis episodes. Average serum gentamicin levels on day 2 were 1.83 ± 0.84 mg/L with levels exceeding 2 mg/L in 22 (43%) cases. The overall cure rate was 64%. No cases of ototoxicity were observed. Day-2 gentamicin levels were not significantly different between patients who did and did not have a complication or cure. Using multivariable logistic regression analysis, failure to cure peritonitis was not associated with either day-2 gentamicin level (adjusted odds ratio (OR) 0.96, 95% confidence interval (CI) 0.25 - 3.73) or continuation of gentamicin therapy beyond day 2 (OR 0.28, 0.02 - 3.56). The only exception was polymicrobial peritonitis, where day-2 gentamicin levels were significantly higher in episodes that were cured (2.06 ± 0.41 vs 1.29 ± 0.71, p = 0.01). In 17 (26%) patients receiving extended gentamicin therapy, day-5 gentamicin levels were not significantly related to peritonitis cure. ♦ Conclusion: Day-2 gentamicin levels did not predict gentamicin-related harm or efficacy during short-course gentamicin therapy for gram-negative PD-related peritonitis, except in cases of polymicrobial peritonitis, where higher levels were associated with cure.

Full Text Available Mycobacterium fortuitum is a ubiquitous, rapidly growing nontuberculous mycobacterium (NTM. It is the most commonly reported NTM in peritoneal dialysis (PD associated peritonitis. We report a case of a 52-year-old man on PD, who developed refractory polymicrobial peritonitis necessitating PD catheter removal and shift to hemodialysis. Thereafter, M. fortuitum was identified in the PD catheter culture and in successive cultures of initial peritoneal effluent and patient was treated with amikacin and ciprofloxacin for six months with a good and sustained clinical response. Months after completion of the course of antibiotics, the patient successfully returned to PD. To our knowledge, this is the first reported case of M. fortuitum peritonitis in the field of polymicrobial PD peritonitis. It demonstrates the diagnostic yield of pursuing further investigations in cases of refractory PD peritonitis. In a systematic review of the literature, only 20 reports of M. fortuitum PD peritonitis were identified. Similar to our case, a delay in microbiological diagnosis was frequently noted and the Tenckhoff catheter was commonly removed. However, the type and duration of antibiotic therapy varied widely making the optimal treatment unclear.

Background The first episode of peritonitis affects survival of the peritoneal membrane as a medium for dialysis as well as survival of patients. The aim of this study is to investigate risk factors associated with the first episode of peritonitis in Southern Chinese continuous ambulatory peritoneal dialysis (CAPD) patients. Methods This is a single-center, retrospective, cohort study. All incident CAPD patients from 1 January 2006 to 31 December 2010 were recruited, and followed up until their first episode of peritonitis or 31 December, 2012. Baseline demographic, socioeconomic, clinical and laboratory data were collected. Cox proportional model was used to determine the factors associated with the first episode of peritonitis. Results In a cumulative 30756.5 patient-months follow-up (the median vintage 26.1 months) of 1117 CAPD patients, 309(27.7%) patients presented the first episodes of peritonitis. The cumulative peritonitis-free survival was 86.2%, 78.1%, 71.4% and 57.8% at 1, 2, 3 and 5 year, respectively. The multivariate analysis showed that factors associated with risk for the first episode of peritonitis were elderly patients (>65 years) [hazard ratio (HR) = 1.427, 95% confidence interval (CI) = 1.051 to 1.938, P = 0.023], male(HR = 1.315, 95% CI = 1.028 to 1.684, P = 0.030), lower education level (HR = 1.446, 95% CI: 1.127 to 1.855, P = 0.004) and albumin peritonitis in Southern Chinese CAPD patients.

To evaluate the volume change of peritoneal inclusion cysts on the follow-up ultrasonography (US). From March 1995 to May 1999, thirty seven women with ultrasonographically diagnosed peritoneal inclusion cysts were included in this study. Six patients underwent surgery for several reasons. Follow-up ultrasonography was performed 70-456 days (mean=191 days) after initial US examination in 12 of the remaining 31 patient with no further treatment. US was performed with a 3.5 or 4 MHz transabdominal probe in all 18 patients who underwent either surgery or follow-up US, and additional tranvaginal US examination using a 5-7 MHz probe in 15 of 18 patients. The volume change of the cysts was recorded for each US examination. Three cysts (25%) (volume=170 cm 3 , 61 cm 3 , and 38 cm 3 , respectively) were completely resolved on the follow-up US while the other nine cysts showed a decreased volume in seven patients (58%) and increased volume in two patients (17%). Spontaneous regression of peritoneal inclusion cysts is more common than it is believed to be, and ultrasonography may be a useful follow-up examination for peritoneal inclusion cysts.

Spontaneous bacterial peritonitis is a complication of ascitic patients with end-stage liver disease (ESLD); spontaneous fungal peritonitis (SFP) is a complication of ESLD less known and described. ESLD is associated to immunodepression and the resulting increased susceptibility to infections. Recent perspectives of the management of the critically ill patient with ESLD do not specify the rate of isolation of fungi in critically ill patients, not even the antifungals used for the prophylaxis, neither optimal treatment. We reviewed, in order to focus the epidemiology, characteristics, and, considering the high mortality rate of SFP, the use of optimal empirical antifungal therapy the current literature.

Infections with Listeria monocytogenes are uncommon but serious, with mortality rate approaching 30% in cases of systemic involvement despite first-line therapy. They are usually caused by ingestion of contaminated foods, but spontaneous infections have also been described. Listeria monocytogenes is a rare cause of peritonitis, and most of the published cases are in patients with cirrhosis and ascites. There are a few reported cases of Listeria peritonitis associated with peritoneal dialysis (PD), primarily isolated peritonitis.If detected early, Listeria peritonitis can be successfully treated with ampicillin, alone or in combination with gentamicin. Vancomycin has been listed as a second-line agent. However, it has been associated with treatment failure.In this case report, we present a patient who developed disseminated listeriosis, with peritonitis as the first manifestation of disseminated infection. This case illustrates the importance of having a high index of suspicion for L. monocytogenes if patients deteriorate despite empiric therapy for PD-associated peritonitis and serves as a further example demonstrating the inadequate coverage of vancomycin for L. monocytogenes .

We explored the relationship between the experience level of nurses and the peritonitis risk in peritoneal dialysis (PD) patients. Our observational cohort study followed 305 incident PD patients until a first episode of peritonitis, death, or censoring. Patients were divided into 3 groups according to the work experience in general medicine of their nurses-that is, least experience (biochemistry, and residual renal function were also recorded. Multivariate Cox regression was used to analyze the association of risks for all-cause and gram-positive peritonitis with patient training provided by nurses at different experience levels. Of the 305 patients, 91 were trained at the initiation of PD by nurses with advanced experience, 100 by nurses with moderate experience, and 114 by nurses with the least experience. Demographic and clinical variables did not vary significantly between the groups. During 13 582 patient-months of follow-up, 129 first episodes of peritonitis were observed, with 48 episodes being attributed to gram-positive organisms. Kaplan-Meier analysis showed that training by nurses with advanced experience predicted the longest period free of first-episode gram-positive peritonitis. After adjustment for some recognized confounders, the advanced experience group was still associated with the lowest risk for first-episode gram-positive peritonitis. The level of nursing experience was not significantly correlated with all-cause peritonitis risk. The experience in general medicine of nurses might help to lower the risk of gram-positive peritonitis among PD patients. These data are the first to indicate that nursing experience in areas other than PD practice can be vital in the training of PD patients.

Full Text Available Colon perforation is an uncommon event usually caused by malignancy, diverticular disease, amoebic colitis, steroid therapy, trauma and ulcerative colitis, but stercoral perforation is very rare. Severe chronic constipation is considered to be the main causative factor in development of stercoral perforation of colon. Sometimes it can also produce catastrophic complications like colonic obstruction, faecal peritonitis and septicaemia. We report a rare case of sigmoid colonic perforation with faecal peritonitis and pneumoperitonium due to faecaloma which was diagnosed after exploratory laparotomy.

We undertook this study to elucidate whether baseline peritoneal membrane transport characteristics are associated with high mortality in incident automated peritoneal dialysis (APD) patients. This retrospective study includes 117 patients who started APD at Yonsei University Health System from 1996 to 2008 and had a PET within 3 months of APD initiation. High transporters were significantly older and had a higher incidence of cardiovascular disease. Patient survival for years 1, 3, and 5 were 85%, 64%, and 35% for high transporter and 94%, 81%, and 68% for non-high transporter group (Ptransport status was not a significant predictor for mortality in this population when the other covariates were included. Even though high transport was significantly associated with mortality in the univariate analysis, its role seemed to be influenced by other comorbid conditions. These findings suggest that the proper management of these comorbid conditions, as well as appropriate ultrafiltration by use of APD and/or icodextrin, must be considered as protective strategies to improve survival in peritoneal dialysis patients with high transport.

Pseudomonas peritonitis is a serious complication of peritoneal dialysis (PD). However, the clinical course of Pseudomonas peritonitis following the adoption of international guidelines remains unclear. We reviewed the clinical course and treatment response of 153 consecutive episodes of PD peritonitis caused by Pseudomonas species from 2001 to 2015. Pseudomonas peritonitis accounted for 8.3% of all peritonitis episodes. The bacteria isolated were resistant to ceftazidime in 32 cases (20.9%), and to gentamycin in 18 cases (11.8%). In 20 episodes (13.1%), there was a concomitant exit site infection (ESI); in another 24 episodes (15.7%), there was a history of Pseudomonas ESI in the past. The overall primary response rate was 53.6%, and complete cure rate 42.4%. There was no significant difference in the complete cure rate between patients who treated with regimens of 3 and 2 antibiotics. Amongst 76 episodes (46.4%) that failed to respond to antibiotics by day 4, 37 had immediate catheter removal; the other 24 received salvage antibiotics, but only 6 achieved complete cure. Antibiotic resistance is common amongst Pseudomonas species causing peritonitis. Adoption of the treatment guideline leads to a reasonable complete cure rate of Pseudomonas peritonitis. Treatment with three antibiotics is not superior than the conventional two antibiotics regimen. When there is no clinical response after 4 days of antibiotic treatment, early catheter removal should be preferred over an attempt of salvage antibiotic therapy.

A 16-year-old female who had end-stage renal disease on 2-month continuous ambulatory peritoneal dialysis (CAPD) presented with perineal pain 4 days before admission. The physical examination revealed bilateral labial edema. Peritoneal scintigraphy was requested after infusing 2 L peritoneal dialysate with direct administration of 370 MBq (10mCi) technetium-99m diethylenetriamine pentra-acetic acid into peritoneal cavity via Tenckhoff catheter. Radioactive uptake from right inguinal to labial region was clearly demonstrated, and this indicated the site of peritoneal leakage. After surgical intervention unilaterally, she continued CAPD without any recurrence (au)

Our aim was to define the epidemiological profile of acute generalized peritonitis in N'Djamena, Chad. This retrospective study, conducted in the general surgery department of the National Reference General Hospital, examined the files of 492 patients who underwent surgery for acute generalized peritonitis from June 2007 to December 2012. Epidemiological, clinical, paraclinical, and therapeutic characteristics were described. Acute generalized peritonitis accounted for 35.2 % of all visceral surgical emergencies. Male patients were at highest risk (sex-ratio 6.5). The patients' mean age was 25.8 years (range 1 to 70 years). All patients had abdominal pain. The leading cause was traumatic visceral perforation by stabbing or a firearm in 226 cases (46 %), followed by diffuse appendiceal peritonitis. Primary peritonitis was rare. The principal procedure was surgical excision and suture. The mean time to consultation was 3 days and the mean hospital stay 8.5 days. The morbidity rate was 16.8 %, dominated by wound infection. The mortality rate was 6.8 %. Abdominal trauma is the major cause of acute generalized peritonitis in N'Djamena. Prognosis depends on time to surgical management.

Bacterial peritonitis remains a life-threatening complication of peritoneal dialysis (PD). Roseomonas is a bacterial genus of pink-pigmented, oxidized, gram-negative coccobacilli that was first named in 1993. Importantly, Roseomonas mucosa exhibits antibiotic resistance, with significant resistance to cephalosporin, which is often selected as an empirical antibiotic regimen for peritonitis in PD patients. We herein report the case of a PD patient with bacterial peritonitis caused by Roseomonas mucosa that was fortunately identified using 16S rRNA gene sequencing and successfully treated with ciprofloxacin. Given that Roseomonas demonstrates resistance to a variety of antibiotics. The administration of empiric antibiotic therapy based on the recommendation of the International Society of Peritoneal Dialysis guidelines occasionally fails, leading to the aggravation of bacterial peritonitis. Hence, nephrologists should consider Roseomonas as one of the potential causative organisms of peritonitis, especially when gram-negative bacilli are resistant to cephalosporin and cannot be identified using standard laboratory methods.

Molecular mechanisms of peritoneal dialysis (PD) ultrafiltration failure, peritoneal neo-angiogenesis, and fibrosis remain to be determined. We aimed to determine the role of heparin-binding EGF-like growth factor (HB-EGF) inhibition on angiogenesis of peritoneal membrane in a PD rat model. 32 male Wistar rats were assigned into (1) control group; (2) uremic non-PD group: subtotal nephrectomy-induced uremic rats without PD; (3) uremic rats subjected to PD: uremic rats that were dialyzed with Dianeal ® for 4 weeks; (4) CRM 197 group: dialyzed uremic rats were supplemented with CRM197, a specific HB-EGF inhibitor. Peritoneal transport function was examined by peritoneal equilibration test. Expression of HB-EGF and EGFR in peritoneal samples were examined by real-time PCR, immunohistochemical staining, and western blot. Progressive angiogenesis and fibrosis were observed in uremic PD rats, and there were associated with decreased net ultrafiltration (nUF), increased permeability of peritoneal membrane, and reduced expression of HB-EGF and EGFR protein and mRNA in uremic PD rats compared to uremic non-PD or control groups (both p CRM197 significantly induced peritoneal membrane permeability, decreased nUF, increased higher vessel density, and reduced pericyte count compared to that of uremic PD rats. The levels of HB-EGF and EGFR expression negatively correlated with vessel density in peritoneal membrane (both p < 0.001). PD therapy was associated with peritoneal angiogenesis, functional deterioration, and downregulation of HB-EGF/EGFR. Pharmacological inhibition of HB-EGF promoted PD-induced peritoneal angiogenesis and fibrosis and ultrafiltration decline, suggesting that HB-EGF downregulation contributes to peritoneal functional deterioration in the uremic PD rat model.

Peritoneal dialysis (PD) program was established in Farwaniya Hospital Kidney Center, Kuwait, in February 2011. Patient recruitment for this modality of treatment was growing steadily. One of the major complications of PD is peritonitis. There is a belief that PD therapy is inferior and carries more complications than hemodialysis, we aimed to show that PD is a good and a non-inferior option for dialysis therapy with comparable outcome in both patient and technique survival. This was a retrospective analysis of all patients who were on PD from February 2011 to December 2014. Peritonitis rate, exit site infection rate, and all-cause mortality rate were all assessed for this period. Peritonitis rate during the 1 st year, 2011, was 0.92 incidents/year. This number had progressively declined in the following years; in 2012, it was 0.65 incidents/year; in 2013, it was 0.58 incidents/year; and in 2014, it was 0.38 incidents/year. This improvement in the rate of peritonitis incidence could be explained by better education of patients and meticulous supervision of the nursing staff. Farwaniya Hospital Kidney Center had an all-cause mortality rate of 9.3% among patients on renal replacement therapy in 2011. In 2012, all-cause mortality rate increased to 17.1%. The following year, 2013, it decreased to 14.3%, and in 2014, all-cause mortality rate dropped further to 7.6%. All-cause mortality rate among PD patients was zero in 2011. In 2012, the all-cause mortality rate in PD was 11.54%, and in 2013, it decreased to 10.52%. Then, again in 2014, the all-cause mortality rate among PD patients was zero. This improvement in all-cause mortality rate could be explained by the better medical care offered to the end-stage renal disease patients, in particular PD patients, in Farwaniya Hospital Kidney Center.

Peritonitis is the major complication of peritoneal dialysis (PD). The aim of our present study is to explore the prognostic value of endotoxin level in PD effluent for the prediction of treatment failure in PD-related peritonitis. We studied 325 peritonitis episodes in 223 patients. PD effluent (PDE) was collected every 5 days for endotoxin level and leukocyte count. Patients were followed for relapsing or recurrent peritonitis. We found 20 episodes (6.2%) had primary treatment failure; 41 (12.6%) developed relapsing, 19 (5.8%) had recurrent, and 22 (6.8%) had repeat episodes. Endotoxin was detectable in the PDE of 19 episodes (24.4%) caused by Gram negative organisms, 4 episodes (6.8%) of mixed bacterial growth, and none of the culture negative episodes or those by Gram positive organisms. For episodes caused by Gram negative bacteria, a detectable endotoxin level in PDE on day 5 had a sensitivity and specificity of 66.7% and 83.3%, respectively, for predicting primary treatment failure. In contrast, PDE leukocyte count > 1000 per mm3 on day 5 had a sensitivity and specificity of 88.9% and 89.1%, respectively; the addition of PDE endotoxin assay did not improve the sensitivity or specificity. We conclude that detectable endotoxin in PDE 5 days after antibiotic therapy might predict primary treatment failure in peritonitis episodes caused by Gram negative organisms. However, the sensitivity and specificity of PDE endotoxin assay was inferior to PDE leukocyte count. © 2016 Asian Pacific Society of Nephrology.

To evaluate the accuracy and safety of ultrasound-guided biopsy of the thickened peritoneal reflections and to determine the efficacy and diagnostic role of this procedure in the differential diagnosis of peritoneal tuberculosis and peritoneal carcinomatosis. Twenty-seven patients with only mildly thickened (25 mm or less) peritoneal reflections without apparent mass formations, and in whom imaging findings were not diagnostic, underwent ultrasound-guided biopsy. Five-MHz linear or convex linear array transducers were used for ultrasound guidance, and an automated gun with 18-gauge (n=3D23) or 20-gauge (n=3D4) needles for tissue sampling. biopsies were performed on the thickened parietal peritoneum (n=3D9), greater omentum (n=3D11), and small bowel mesentery (n=3D7), and the results were compared with the final diagnosis determined by radiologic/clinical follow-up (n=3D17) or laparoscopic biopsy (n=3D10). Complications and changes in hemoglobin and hematocrit levels after the procedure were evaluated. Specimens adequate for pathologic examination were obtained in all 27 patients. The histopathologic results were metastatic carcinomatosis (n=3D15), peritoneal tuberculosis (n=3D8), and chronic granulomatous inflammation (n=3D4). Specific pathologic diagnosis was obtained in all patients except the four with chronic granulomatous inflammation. Differentiation between benignancy and malignancy was possible in all patients and the histopathologic specific accuracy rate was 100%. No clinically significant complications were observed. In 24 patients with ascites at the site of the biopsy, transient bleeding was observed immediately after the procedure, but this stopped spontaneously within a few minutes. Post-procedural hemoglobin and hematocrit levels were only minimally lower (mean values of 0.9 g/dL and 3.0%, respectively) than pre-procedurally. Ultrasound-guided biopsy of thickened peritoneal reflections is a safe and effective diagnostic procedure and is useful in

The best surgical strategy for the management of perforated diverticulitis with generalized peritonitis of the sigmoid colon is not clearly defined. The aim of this retrospective cohort study was to evaluate the value of a damage control strategy. All patients who underwent emergency laparotomy for perforated diverticular disease of the sigmoid colon with generalized peritonitis between 2010 and 2015 were included. The damage control strategy (study group), included a two- stage procedure: limited resection of the diseased colonic segment, closure of proximal colon and distal stump, and application of an abdominal vacuum at the initial surgery followed by second-look laparotomy 24-48 h later At this point a choice was made between anastomosis and Hartmann's procedure. The control group consisted of patients receiving definitive reconstruction (anastomosis or Hartmann's procedure) at the initial operation. Thirty-seven patients were included in the study. Damage control strategy was applied in 19 patients and the control group consisted of 18 patients. Both groups were comparable in terms of demographics, severity of peritonitis, and comorbidities. The overall postoperative mortality was 11 % (n = 4). There were no statistically significant differences between both groups regarding postoperative morbidity and mortality; however, a significantly higher proportion of patients in the control group had a stoma after the initial hospital stay (83 vs. 47 %, p = 0.038). This difference was still significant after adjustment for sex, age, Mannheim Peritonitis Index, American Society of Anesthesiologists class and presence of septic shock at presentation. At the end of the follow-up period, 15 of 17 survivors in the study group and 13 of 16 survivors in the control group had their intestinal continuity restored (p = 0.66). Damage control strategy in patients with generalized peritonitis due to perforated diverticulitis leads to a significantly reduced stoma rate

The Standardizing Care to improve Outcomes in Pediatric End stage renal disease (SCOPE) Collaborative aims to reduce peritonitis rates in pediatric chronic peritoneal dialysis patients by increasing implementation of standardized care practices. To assess this, monthly care bundle compliance and annualized monthly peritonitis rates were evaluated from 24 SCOPE centers that were participating at collaborative launch and that provided peritonitis rates for the 13 months prior to launch. Changes in bundle compliance were assessed using either a logistic regression model or a generalized linear mixed model. Changes in average annualized peritonitis rates over time were illustrated using the latter model. In the first 36 months of the collaborative, 644 patients with 7977 follow-up encounters were included. The likelihood of compliance with follow-up care practices increased significantly (odds ratio 1.15, 95% confidence interval 1.10, 1.19). Mean monthly peritonitis rates significantly decreased from 0.63 episodes per patient year (95% confidence interval 0.43, 0.92) prelaunch to 0.42 (95% confidence interval 0.31, 0.57) at 36 months postlaunch. A sensitivity analysis confirmed that as mean follow-up compliance increased, peritonitis rates decreased, reaching statistical significance at 80% at which point the prelaunch rate was 42% higher than the rate in the months following achievement of 80% compliance. In its first 3 years, the SCOPE Collaborative has increased the implementation of standardized follow-up care and demonstrated a significant reduction in average monthly peritonitis rates.

Spontaneous Bacterial Peritonitis Caused by Infection with Listeria monocytogenes

Directory of Open Access Journals (Sweden)

Michael Vincent F. Tablang

2008-11-01

Full Text Available Spontaneous bacterial peritonitis is a severe and life-threatening complication in patients with ascites caused by advanced liver disease. The organisms most commonly involved are coliform bacteria and third-generation cephalosporins are the empiric antibiotics of choice. This is an uncommon case of spontaneous bacterial peritonitis caused by Listeria monocytogenes in a female patient with liver cirrhosis from autoimmune hepatitis. She did not improve with ceftriaxone and her course was complicated by hepatic encephalopathy, seizures and multi-organ failure. This case emphasizes that a high index of suspicion should be maintained for timely diagnosis and treatment. Listerial peritonitis should be suspected in patients with end-stage liver disease and inadequate response to conventional antibiotics within 48–72 h. Ampicillin/sulbactam should be initiated while awaiting results of ascitic fluid or blood culture.

In a prospective study of intraperitoneal opsonins in 30 patients undergoing continuous ambulatory peritoneal dialysis (CAPD), the IgG concentration, the fibronectin concentration, the specific antistaphylococcal antibody level, and the opsonic activity against Staphylococcus epidermidis were...... measured in peritoneal dialysis effluent from the initiation of CAPD and monthly for 6 months. Significant correlation was found between the four assays, but the interindividual and intraindividual variations were considerable. No statistically significant correlation was observed between susceptibility...... of the patients to CAPD-related infectious peritonitis and any of the above-mentioned parameters of humoral defense. We conclude that at the present time it is not feasible to use these assays for the establishment of prognosis with regard to peritonitis in CAPD....

Peritoneal dialysis (PD) exchange procedure is complex. Patients with cognitive impairment (CI) may require assistance. We studied the prevalence of CI among PD patients, its impact on PD-related peritonitis and the outcome of assisted PD. Cantonese version of Mini-Mental State examination (CMMSE) was performed in 151 patients newly started on PD. Data on patient characteristics including demographics, co-morbidities, blood parameters, medications, and number of PD-related peritonitis in the first 6 months were collected. 151 subjects were recruited. The age of studied patients was 60 ± 15.0 years, and 45% were female. The prevalence of CI was 13.9% using education-adjusted cut-off of CMMSE. Patients older than 65-year-old, female, and lower education level were independent risk factors for CI (OR 9.27 p = 0.001, OR 14.84 p = 0.005, and OR 6.10 p = 0.009, respectively). Age greater than 65-year old is an independent risk factor for PD-related peritonitis but CI was not. Patients requiring assisted PD were of older age (p peritonitis (p = 0.07). CI is common among local PD patients. Overall, CI could not be identified as an independent risk factor for PD peritonitis. There is a higher prevalence of CI among assisted PD patients but helpers may not completely eliminate the risk of PD-related peritonitis.

Seventy-three abdominopelvic contrast-enhanced CT scans obtained in 60 patients with peritoneal tumor spread were reviewed retrospectively to determine the CT signs of peritoneal malignancy. Ascites was present in 54 studies (74%) and was the most common CT finding. Loculation of the fluid occurred in 25 (46%) of these. In nine (17%) of the 54, a new finding, absence of cul-de-sac fluid in the presence of generalized ascites, was noted. Parietal peritoneal thickening with contrast enhancement of the peritoneum, making the peritoneum visible as a thin line along the abdominal wall, was present in 45 (62%) of studies. This is believed to represent confluent peritoneal metastases. Small-bowel involvement was present in half of the cases (wall thickening and irregularity with or without obstruction). Tumor involvement of the omentum was visible as soft-tissue permeation of fat, enhancing nodules, and/or an omental cake. Of the 26 patients without a previously known malignancy, identification of the primary tumor in addition to peritoneal carcinomatosis was possible in 13 (50%). Appreciation of the spectrum of CT findings in peritoneal carcinomatosis is essential for accurate evaluation of scans in patients with abdominopelvic malignancies.

Peritonitis is a common complication in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD). In this retrospective study, peritonitis rates and patient survival of 180 patients on CAPD and 128 patients on APD were compared in the period from January 2005 to December 2014 at Al-Nafisi Center in Kuwait. All patients had prophylactic topical mupirocin at catheter exit site. Patients on CAPD had twin bag system with Y transfer set. The peritonitis rates were 1 in 29 months in CAPD and 1 in 38 months in APD (p peritonitis free patients over 10-year period in CAPD and APD were 49 and 60%, respectively (p peritonitis was 10.25 ± 3.1 months in CAPD compared to 16.1 ± 4 months in APD (p peritonitis was 13.1 ± 1 and 14 ± 1.4 months respectively (p = 0.3) whereas in peritonitis free patients it was 15 ± 1.4 months in CAPD and 23 ± 3.1 months in APD (p = 0.025). APD had lower incidence rate of peritonitis than CAPD. Patient survival was better in APD than CAPD in peritonitis free patients but was similar in patients who had peritonitis.

[Surgical treatment of secondary peritonitis: A continuing problem. German version].

Secondary peritonitis remains associated with high mortality and morbidity rates. Treatment of secondary peritonitis is still challenging even in the era of modern medicine. Surgical intervention for source control remains the cornerstone of treatment besides adequate antimicrobial therapy and when necessary intensive medical care measures and resuscitation. A randomized clinical trial showed that relaparotomy on demand (ROD) after initial emergency surgery was the preferred treatment strategy, irrespective of the severity and extent of peritonitis. The effective and safe use of ROD requires intensive monitoring of the patient in a setting where diagnostic tests and decision making about relaparotomy are guaranteed round the clock. The lack of knowledge on timely and adequate patient selection, together with the lack of use of easy but reliable monitoring tools seem to hamper full implementation of ROD. The accuracy of the relaparotomy decision tool is reasonable for prediction of the formation of peritonitis and necessary selection of patients for computed tomography (CT). The value of CT in the early postoperative phase is unclear. Future research and innovative technologies should focus on the additive value of CT after surgical treatment for secondary peritonitis and on the further optimization of bedside prediction tools to enhance adequate patient selection for interventions in a multidisciplinary setting.

BACKGROUND: In peritoneal dialysis (PD) total net ultrafiltration (NUF) is dependent on transport through small pores and through water channels in the peritoneum. These channels are impermeable to solutes, and therefore, crystalloid osmotic-induced free water transport occurs through them. Several

Can we identify modifiable risk factors for peritonitis in patients undergoing peritoneal dialysis (PD)? We aimed to determine whether housing standard, PD exchange technique or patient motivation might be modifiable risks for peritonitis. We also explored the relationship between lack of motivation and depression. Nurse home visits assessed PD exchange technique, environment and patient motivation. Motivation scores were correlated separately with an Apathy Evaluation Score and a depression score using PHQ-9 questionnaires. Home hygiene, exchange technique and motivation were above average in 53%, 56% and 60%, respectively in 104 patients undergoing PD. After 15 months, 25.9% patients developed peritonitis but nurses' ratings of homes and exchange techniques were not predictive. Low patient motivation was predictive. Patients rated to have above or below median motivation had significantly different Apathy Scores (p = 0.0002). Unmotivated depressed patients were significantly more likely to develop peritonitis compared to motivated depressed patients. Lack of motivation predicted peritonitis particularly if associated with depression. Further studies are required focusing on specific motivation scoring schemes and the psychosocial support that might lead to better outcomes. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Peritoneal dialysis: a primary care perspective.

Saxena, Ramesh; West, Cheryl

2006-01-01

As the population of chronic kidney disease (CKD) and end-stage renal disease (ESRD) grows at an alarming rate, primary care physicians will increasingly be involved in the management of these patients. Early recognition of CKD and timely referral to a nephrologist when glomerular filtration rate approaches 30 mL/min/1.73 m(2) is extremely important to improve ESRD outcome and appropriate selection of dialysis modality. Peritoneal dialysis (PD) remains a viable treatment option for ESRD patients. PD is less expensive dialysis modality and may provide a survival advantages over hemodialysis in first 2 to 4 years of treatment. Preserving residual renal function (RRF) is of paramount importance to prolong the survival outcomes in PD patients. Thus preservation of RRF is an important goal in the management of PD patients. Every effort should be made to avoid nephrotoxic drugs like aminoglycosides and nonsteroidal anti-inflammatory drugs, and limit the use of radiocontrast agents in PD patients with RRF. Judicious use of prophylactic antibiotics to prevent peritonitis would further help to reduce morbidity from PD. Protecting peritoneal membrane from long-term toxic and metabolic effects of the conventional glucose-based solutions is another objective to further improve PD outcome. Development of new, more biocompatible PD solutions holds promise for the future. One such solution, icodextrin, is now approved for use in the United States. Although extremely safe to use, it is associated with unique metabolic effects that may concern primary care physicians. They include false elevation of blood glucose, a reversible increase in serum alkaline phosphatase and a false decline in serum amylase. Monitoring of glycemia by assays that use glucose dehydrogenase pyrroloquinoline quinone enzymes should be avoided and serum amylase alone should not be relied on in diagnosing pancreatitis in patients on icodextrin.

The WNT signaling pathway is involved in wound healing and fibrosis. We evaluated the WNT signaling pathway in peritoneal membrane injury. We assessed WNT1 protein expression in the peritoneal effluents of 54 stable peritoneal dialysis (PD) patients and WNT-related gene expression in ex vivo mesothelial cell cultures from 21 PD patients. In a transforming growth factor beta (TGFB) mediated animal model of peritoneal fibrosis, we evaluated regulation of the WNT pathway and the effect of WNT inhibition on peritoneal fibrosis and angiogenesis. WNT1 and WNT2 gene expression were positively correlated with peritoneal membrane solute transport in PD patients. In the mouse peritoneum, TGFΒ-induced peritoneal fibrosis was associated with increased expression of WNT2 and WNT4. Peritoneal b-catenin protein was significantly upregulated after infection with AdTGFB along with elements of the WNT signaling pathway. Treatment with a b-catenin inhibitor (ICG-001) in mice with AdTGFB-induced peritoneal fibrosis resulted in attenuation of peritoneal angiogenesis and reduced vascular endothelial growth factor. Similar results were also observed with the WNT antagonist Dickkopf related protein (DKK) 1. In addition to this, DKK-1 blocked epithelial to mesenchymal transition and increased levels of the cell adhesion protein E-cadherin. We provide evidence that WNT signaling is active in the setting of experimental peritoneal fibrosis and WNT1 correlates with patient peritoneal membrane solute transport in PD patients. Intervention in this pathway is a possible therapy for peritoneal membrane injury.

Full Text Available Peritoneal dialysis (PD is a well-established modality for treatment of patients with end-stage renal disease, giving excellent patient and technique survival rates. In Saudi Arabia, data collected by the Saudi Center for Organ Transplantation showed that in 2008, patients on PD accounted for a mere 4.8% of total patients on renal replacement therapy, including hemodialysis and renal transplantation. This study was conducted to identify the characteristics of membrane per-meability in the Saudi population and to assess the role of various factors affecting solute transport across the peritoneal membrane. We followed up a total of 52 patients on Continuous Ambulatory Peritoneal Dialysis (CAPD as well as Automated Peritoneal Dialysis (APD, being treated in the PD unit of the King Khalid University Hospital, Riyadh. There were 30 female and 22 male patients; 14 patients were using CAPD while 38 patients were on APD. The mean age of the patients was 50.5 years, with a range of 14-86 years. The average body mass index (BMI was 27.1 kg/m 2 and the mean body surface area (BSA of the study patients was 1.71 m 2 . A standardized PET test was performed on all patients, 4-6 weeks after initiation of regular PD. The Kt/V and creatinine clearance measured 6-8 weeks after initiation of dialysis were 1.96 and 56.59 L/week, respectively. Residual renal function was assessed on the basis of daily urine output, using 24-hour urine collection. The mean serum urea con-centration was 16.91 mmol/L and mean serum creatinine was 702 μmol/L. According to the Peritoneal Equiliberation Test (PET, 8% of the subjects belonged to the high trans-porter category, 44% patients belonged to the high-average transport group, 46% to the low-average category and 2% came in the low transporter category. Our study suggests that the patient characteristics and demographic para-meters seen in the Saudi population are comparable to those seen in other studies from the Middle East and

Peritoneal dialysis (PD) constitutes the preferred dialysis modality for children requiring renal replacement therapy with peritonitis being one of the most common complications of PD. This study was performed to evaluate the epidemiology, microbiology, and outcomes of PD-associated peritonitis in Greek children for a 10-year period. A total of 27 patients (16 males) with a mean age 121.8 ± 57.2 months were retrospective analyzed. Patients were on PD therapy for a mean duration of 45.2 ± 26.1 months. We found 23 episodes of PD-associated peritonitis occurred in 9 out of 27 patients (0.23 episodes/patient-year), with four patients experienced two or more peritonitis episodes. Gram-positive bacteria were responsible for 15 (65.2%) peritonitis episodes, with Staphylococcus aureus being the predominant specie isolated in 30.4% of cases. A total of seven episodes of exit-site infections (ESIs) were identified in five patients (0.069 episodes/patient-year) with the most common bacteria isolated being S. aureus (57.4%). Initial antibiotic treatment included intraperitoneal vancomycin plus ceftazidime in the majority of cases (82.6%). At the end of study, 12 (44.4%) patients remained on PD, 11 (41.8%) underwent renal transplantation, 2 (7.4%) shifted to hemodialysis and unfortunately, two patients (7.4%) died. Conclusively, our study revealed a noticeable low peritonitis and ESIs rate as compared to international data and represents the first evaluation of the characteristics and outcomes of peritonitis in the Greek pediatric PD population.

Possible relationships between the dialysate-to-plasma creatinine equilibration ratio (D/Pcreatinine 4 hour), duration of peritoneal dialysis treatment, number of peritonitis episodes, and mass appearance rates of three connective tissue markers [carboxyterminal propeptide of type I procollagen...... (PICP), aminoterminal propeptide of type III procollagen (PIIINP), and carboxyterminal telopeptide of type I collagen (ICTP)] were studied in 19 nondiabetic peritoneal dialysis patients. The absence of correlation between the mass appearance rates of the markers and the duration of dialysis treatment...... as well as the number of peritonitis episodes supports the concept that peritoneal dialysis does not cause persistent changes in the deposition and degradation rates of collagen. A correlation between the D/Pcreatinine 4 hr and the PICP mass appearance rates was found. Since it is unlikely...

2012-02-01

Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation. A diagnosis of cardiomyopathy with acute heart failure, secondary to valvular heart disease, was secured. Acute peritonitis as the presenting feature of valvular cardiomyopathy is a rare clinical entity.

The major complication of peritoneal dialysis (PD) is the development of peritonitis, an infection within the abdominal cavity, primarily caused by bacteria. PD peritonitis is associated with significant morbidity, mortality and health care costs. Staphylococcus epidermidis is the most frequently isolated cause of PD-associated peritonitis. Mesothelial cells are integral to the host response to peritonitis, and subsequent clinical outcomes, yet the effects of infection on mesothelial cells are not well characterised. We systematically investigated the early mesothelial cell response to clinical and reference isolates of S. epidermidis using primary mesothelial cells and the mesothelial cell line Met-5A. Using an unbiased whole genome microarray, followed by a targeted panel of genes known to be involved in the human antibacterial response, we identified 38 differentially regulated genes (adj. p-value peritonitis. This study provides new insights into early mesothelial cell responses to infection with S. epidermidis, and confirms the importance of validating findings in primary mesothelial cells.

An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

International guidelines recommend the use of a prophylactic antibiotic before the peritoneal dialysis (PD) catheter can be inserted. The main objective of this study was to assess whether this practice is associated with a lower risk of early peritonitis and to estimate the magnitude of the centre effect. A retrospective, multi-centric study was conducted, in which data from the French Language Peritoneal Dialysis Registry was analysed. Patients were separated into 2 groups based on whether or not prophylactic antibiotics were used prior to catheter placement. Out of the 2,014 patients who had a PD catheter placed between February 1, 2012 and December 31, 2014, 1,105 were given a prophylactic antibiotic. In a classical logit model, the use of prophylactic antibiotics was found to protect the individual against the risk of early peritonitis (OR 0.67, 95% CI 0.49-0.92). However, this association lost significance in a mixed logistic regression model with centre as a random effect: OR 0.73 (95% CI 0.48-1.09). Covariates associated with the risk of developing early peritonitis were age over 65: OR 0.73 (95% CI 0.39-0.85), body mass index over 35 kg/m2: OR 1.99 (95% CI 1.13-3.47), transfer to PD due to graft failure: OR 2.24 (95% CI 1.22-4.11), assisted PD: OR 1.96 (95% CI 1.31-2.93), and the use of the Moncrief technique: OR 3.07 (95% CI 1.85-5.11). There is a beneficial effect of prophylactic antibiotic used prior to peritoneal catheter placement, on the occurence of early peritonitis. However, the beneficial effect could be masked by a centre effect. © 2016 S. Karger AG, Basel.

State-of-the-art imaging of peritoneal carcinomatosis

International Nuclear Information System (INIS)

Pfannenberg, C.; Schwenzer, N.F.; Bruecher, B.L.

2012-01-01

Imaging studies are essential in the evaluation of patients with suspected or known peritoneal malignancy. Despite major advances in imaging technology in the last few years, the early and adequate detection of a peritoneal dissemination remains challenging because of the great variety in size, morphology and location of the peritoneal lesions. New therapeutic approaches in peritoneal-based neoplasms combining cytoreductive surgery and peritonectomy with hyperthermic intraoperative chemotherapy (HIPEC) suggest improved long-term survival, provided that a complete (macroscopic) cytoreduction is achieved. The preoperative radiological assessment of the extent and distribution of peritoneal involvement plays a vital role in the patient selection process. Despite its known limited accuracy in detecting small peritoneal lesions and the involvement of the small bowel/mesentery, contrast-enhanced MDCT remains the standard imaging modality in the assessment of peritoneal carcinomatosis. MRI, especially with diffusion-weighted images, and FDG-PET/CT are promising methods for the evaluation of peritoneal carcinomatosis with superior results in recent studies, but still have a limited role in selected cases because of high costs and limited availability. Generally, to obtain the most precise readings of peritoneal carcinomatosis, an optimized examination protocol and dedicated radiologists with a deep knowledge of peritoneal pathways and variable morphologies of peritoneal disease are required.

♦ The standard treatment of peritoneal dialysis (PD)-associated peritonitis (PD-peritonitis) is intraperitoneal (IP) administration of antibiotics. Only limited data on the pharmacokinetics and appropriateness of contemporary dose recommendations of IP cefalothin and cefazolin exist. The aim of this study was to describe the pharmacokinetics of IP cefalothin and cefazolin in patients treated for PD-peritonitis. ♦ As per international guidelines, IP cefalothin or cefazolin 15 mg/kg once daily was dosed with gentamicin in a 6-hour dwell to patients with PD-peritonitis during routine care. Serial plasma and PD effluent samples were collected over the first 24 hours of therapy. Antibiotic concentrations were quantified using a validated chromatographic method with pharmacokinetic analysis performed using a non-compartmental approach. ♦ Nineteen patients were included (cefalothin n = 8, cefazolin n = 11). The median bioavailability for both antibiotics exceeded 92%, but other pharmacokinetic parameters varied markedly between antibiotics. Both antibiotics achieved high PD effluent concentrations throughout the antibiotic dwell. Cefazolin had a smaller volume of distribution compared with cefalothin (14 vs 40 L, p = 0.003). The median trough total plasma antibiotic concentration for cefazolin and cefalothin during the dwell differed (plasma 56 vs 13 mg/L, p Peritoneal Dialysis.

Objective: To investigate the clinical significance of peritoneal and retroperitoneal edema in patients with de-compensated cirrhosis (DCC). Methods: Forty-four patients, were identified with DCC on the basis of clinic and laboratory examinations, except the cases with mesenteric, omental and retroperitoneal edema caused by inflammatory and malignant diseases. The diagnosis of edema depended upon hyper-density in peritoneal and retroperitoneal. The degree of edema was divided into minor, middle, and sever types based on the extent of edema. Ascites, varices, serum albumin (ALB) levels, and hyaluronic acid (HA) levels were also documented. Correlations between the laboratory and CT findings were analyzed. Results: The severity of peritoneal edema was correlated with decreasing serum ALB (r s = 0.7088, P s = 0.5294, P s = 0.5440, P s = 0.1335, P > 0.05). Conclusion: CT findings of the edema in peritoneal and retroperitoneal may indicate the severity of the liver cirrhosis

To evaluate 8-hydroxy-2-deoxyguanosine (8-OHdG) and 8-isoprostane levels in the peritoneal fluid (PF) of women with endometriosis. One hundred and ten women with laparoscopically and histopathologically confirmed endometriosis and, as reference groups, 119 patients with simple serous (n=78) and dermoid (n=41) ovarian cysts were studied. Peritoneal fluid 8-OHdG and 8-isoprostane concentrations were evaluated by enzyme-linked immunosorbent assays. 8-OHdG and 8-isoprostane levels in peritoneal fluid were significantly higher in patients with endometriosis compared with the reference groups. Higher PF 8-OHdG and 8-isoprostane concentrations were observed in patients with advanced stages of endometriosis. A statistically significant positive correlation was found between 8-OHdG and 8-isoprostane levels in peritoneal fluid. Endometriosis induces greater oxidative stress and frequent DNA mutations in peritoneal fluid than nonendometriotic ovarian cysts. The most severe oxidative stress occurs in the peritoneal cavity of women with more advanced stages of the disease. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To define prognostic criteria of efficacy of programmed laparoscopic sanitation of the abdominal cavity in peritonitis. There were 32 patients after programmed laparoscopic sanitation of abdominal cavity for peritonitis due to different acute surgical diseases. Subsequently 12 of them required relaparotomy due to poor effectiveness of laparoscopic sanitation. Comprehensive clinical examination and laboratory assessment of some indexes of homeostasis and oxidative status were conducted. Prognostic clinical and laboratory criteria of efficacy of laparoscopic abdominal sanitation were suggested after analysis of intraoperative data during primary surgery and laboratory values in the 1st postoperative day. The offered prognostic criteria allow to define further management of peritonitis patients after primary laparotomy.

Early diagnosis and management of peritoneal metastases from colorectal cancer patients are difficult clinical challenges. The aims of this study were to evaluate the clinical significance of tumor markers and cytology in peritoneal effusions (PE) and peritoneal irrigation fluid (PI) and to determine their value as prognostic indicators in this disease. Two hundred thirty-four consecutive patients who underwent abdominal surgery for colorectal cancer from January 2006 to December 2007 were included, and tumor markers and cytology in PE and PI were analyzed prospectively. The incidence of free cancer cells retrieved from peritoneal samples was 7.9%. Cytology was positive in 40.0% by Papanicolaou and Giemsa staining, 73.3% by hematoxylin and eosin staining of cell blocks, and 66.7% by carcinoembryonic antigen (CEA) and calretinin immunohistochemistry. Multivariate analysis revealed that peritoneal CEA and cancer antigen (CA) 19-9 in PI were correlated with peritoneal metastasis and cytology. Level of peritoneal fluid CEA was statistically significantly correlated with recurrence and peritoneal metastatic recurrence in patients with negative peritoneal cytology. Cytology, peritoneal CEA, and peritoneal CA 19-9 showed correlations with cancer-free survival and overall survival. These correlations demonstrate the importance of continuous follow-up of peritoneal metastasis if there is positive cytology or an increase in CEA and CA 19-9 in peritoneal fluid.

Peritoneal mesothelioma: CT and MRI findings

Two patients with histologically proven diagnosis of peritoneal mesothelioma are presented. Both patients had CT scans of the abdomen. The second patient was also examined with MRI. Although imaging findings are striking, they are non-specific and diagnosing peritoneal mesothelioma in the absence of pleural calcification or pleural plaque on chest radiograph or CT is difficult. However, it is possible to suggest the correct diagnosis in a patient with the presence of non-calcified omental and peritoneal infiltration or masses without liver secondaries or lymphadenopathy. Magnetic resonance imaging with its multi-planar capabilities is a highly sensitive non-invasive modality in the evaluation of malignant peritoneal mesothelioma and can demonstrate the exact site and clarify whether the mass is arising from the peritoneal surface or within a visceral organ.

Full text: Peritoneal carcinomatosis can be difficult to diagnose, as CT is insensitive, with peritoneal biopsy and lavage often subject to problems of sampling error. The aim of our study was to evaluate the role of FDG PET in detecting peritoneal carcinomatosis in patients with biopsy-proven metastases from stomach, ovarian and adrenal cancer and mesothelioma. 92 FDG-PET scans of patients with stomach (49), ovarian (14) adrenal cancer (7) and mesothelioma (22) were reviewed. Studies were performed 45 minutes following IV injection of 10 mCi of 18 F-FDG. Of this group 15 patients had biopsy-proven findings of peritoneal disease while 14 had PET studies reported as suspicious for peritoneal metastasis. Of the 15 biopsy-positive patients, FDG PET was positive in 7, CT in 6 and either PET or CT in 10 (sensitivities 46.6,40.0 and 66.6% respectively). In a further 4 patients without biopsies, where other imaging studies confirmed peritoneal disease, PET was also positive. 2 distinct abnormal scintigraphic patterns of focal and uniform FDG uptake were identified corresponding to nodular and diffuse peritoneal disease at pathology. Our study demonstrates that FDG PET adds to conventional imaging in the staging of peritoneal carcinomatosis. It is also a useful diagnostic tool when peritoneal biopsy is either unavailable or inappropriate. We have identified 2 distinct scintigraphic patterns which appear to predict the presence of either nodular or diffuse peritoneal pathology.Copyright (2002) The Australian and New Zealand Society of Nuclear Medicine Inc

When cancer cells from a growing primary neoplasm reach the peritoneal surface, they are carried out by the peritoneal fluid and disseminated throughout the peritoneal cavity.the location of implants development is governed mostly by peritoneal fluid circulation and by anatomic pathways formed by peritoneal reflections, namely ligaments, mesenteries and omenta. The most common sites where the peritoneal fluid may temporarily arrested facilitating implantation of cancer cells include cul-de-sac, distal small bowel mesentery, right paracolic gutter, posterior sub-hepatic space, greater omentum and subphrenic spaces. MDCT with thin collimation and i.v contrast material supplemented by multiplanar reconstructions is the primary imaging modality for the investigation of peritoneal carcinomatosis. Ascitis, contrast enhanced smooth, nodular, or plaque-like peritoneal thickening, peritoneal nodules, plaques or masses, rounded, ill-defined soft-tissue or cystic mesenteric masses, mesenteric fixation with increased attenuation values and thickening, irregular soft-tissue permeation of omental fat or confluent solid omental masses are the most frequent CT findings of peritoneal carcinomatosis. CT has a sensitivity and specificity between 85-95%, depending on the size, location and applied examination protocol. MR imaging using a post-gadolinium enhanced 3dFlASH sequence with fat saturation may alternatively

Full Text Available Residual renal function (RRF in patients with end-stage renal disease (ESRD receiving renal replacement therapy is defined as the ability of native kidneys to eliminate water and uremic toxins. Preserved RRF improves survival and quality of life in adult ESRD patients treated with peritoneal dialysis. In children, RRF was shown not only to help preserve adequacy of renal replacement therapy but also to accelerate growth rate, improve nutrition and blood pressure control, reduce the risk of adverse myocardial changes, facilitate treatment of anemia and calcium-phosphorus balance abnormalities, and result in reduced serum and dialysate fluid levels of advanced glycation end-products. Factors contributing to RRF loss in children treated with peritoneal dialysis include the underlying renal disease such as hemolytic-uremic syndrome and hereditary nephropathy, small urine volume, severe proteinuria at the initiation of renal replacement therapy, and hypertension. Several approaches can be suggested to decrease the rate of RRF loss in pediatric patients treated with chronic peritoneal dialysis: potentially nephrotoxic drugs (e.g., aminoglycosides, episodes of hypotension, and uncontrolled hypertension should be avoided, urinary tract infections should be treated promptly, and loop diuretics may be used to increase salt and water excretion.

Morelle, Johann; Devuyst, Olivier

We review the molecular mechanisms of peritoneal transport and discuss how a better understanding of these mechanisms is relevant for dialysis therapy. Peritoneal dialysis involves diffusion and osmosis through the highly vascularized peritoneal membrane. Computer simulations, expression studies and functional analyses in Aqp1 knockout mice demonstrated the critical role of the water channel aquaporin-1 (AQP1) in water removal during peritoneal dialysis. Pharmacologic regulation of AQP1, either through increased expression or gating, is associated with increased water transport in rodent models of peritoneal dialysis. Water transport is impaired during acute peritonitis, despite unchanged expression of AQP1, resulting from the increased microvascular area that dissipates the osmotic gradient across the membrane. In long-term peritoneal dialysis patients, the fibrotic interstitium also impairs water transport, resulting in ultrafiltration failure. Recent data suggest that stroke and drug intoxications might benefit from peritoneal dialysis and could represent novel applications of peritoneal transport in the future. A better understanding of the regulation of osmotic water transport across the peritoneum offers novel insights into the role of water channels in microvascular endothelia, the functional importance of structural changes in the peritoneal interstitium and the transport of water and solutes across biological membranes in general.

Full Text Available Background: Intestinal anastomosis in severely ill children with peritonitis from intestinal perforation, intestinal gangrene or anastomotic dehiscence (acute intestinal disease is associated with high morbidity and mortality. Enterostomy as a damage control measure may be an option to minimize the high morbidity and mortality. This report evaluates the role of damage control enterostomy in the treatment of these patients. Materials and Methods: A retrospective review of 52 children with acute intestinal disease who had enterostomy as a damage control measure in 12 years. Results: There were 34 (65.4% boys and 18 (34.6% girls aged 3 days-13 years (median 9 months, comprising 27 (51.9% neonates and infants and 25 (48.1% older children. The primary indication for enterostomy in neonates and infants was intestinal gangrene 25 (92.6% and perforated typhoid ileitis 22 (88% in older children. Enterostomy was performed as the initial surgery in 33 (63.5% patients and as a salvage procedure following anastomotic dehiscence in 19 (36.5% patients. Enterostomy-related complications occurred in 19 (36.5% patients, including 11 (21.2% patients with skin excoriations and eight (15.4% with hypokalaemia. There were four (7.7% deaths (aged 19 days, 3 months, 3½ years and 10 years, respectively directly related to the enterostomy, from hypokalaemia at 4, 12, 20 and 28 days postoperatively, respectively. Twenty other patients died shortly after surgery from their primary disease. Twenty of 28 surviving patients have had their enterostomy closed without complications, while eight are awaiting enterostomy closure. Conclusion: Damage-control enterostomy is useful in management of severely ill children with intestinal perforation or gangrene. Careful and meticulous attention to fluid and electrolyte balance, and stoma care, especially in the first several days following surgery, are important in preventing morbidity and mortality.

Monocytes and macrophages are important effectors and regulators of inflammation, and both their differentiation and activation are regulated strictly in response to environmental cues. Angiopoietin-like protein 2 (Angptl2) is a multifaceted protein, displaying many physiological and pathological functions in inflammation, angiogenesis, hematopoiesis, and tumor development. Although recent studies implicate Angptl2 in chronic inflammation, the mechanisms of inflammation caused by Angptl2 remain unclear. The purpose of the present study was to elucidate the role of Angptl2 in inflammation by understanding the effects of Angptl2 on monocytes/macrophages. We showed that Angptl2 directly activates resident murine peritoneal monocytes and macrophages and induces a drastic upregulation of the transcription of several inflammatory genes including nitric oxide synthase 2 and prostaglandin-endoperoxide synthase 2, and several proinflammatory cytokine genes such as interleukin (IL)-1β, IL-6, TNFα, and CSF2, along with activation of ERK, JNK, p38, and nuclear factor kappa B signaling pathways. Concordantly, proinflammatory cytokines IL-1β, IL-6, TNFα, and GM-CSF, were rapidly elevated from murine peritoneal monocytes and macrophages. These results demonstrate a novel role for Angptl2 in inflammation via the direct activation of peritoneal monocytes and macrophages. - Highlights: • Angptl2 directly activates resident murine peritoneal monocytes and macrophages. • Angptl2 induces a drastic upregulation of expression of inflammatory genes. • Angptl2 induces activation of ERK, JNK, p38, and nuclear factor kappa B signaling pathways. • Angptl2 does not activate bone marrow derived macrophages or macrophage cell lines.

Full Text Available The hemolytic uremic syndrome (HUS, characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure, represents one of the major causes of acute renal failure in infancy and childhood. The typical form occurring after an episode of diarrhea caused by Escherichia coli is the most frequent in children. Other microorganisms also may be responsible for HUS, such as Streptococcus pneumoniae, which causes more severe forms of the disease. We report an 8-month-old girl who presented with pneumonia and subsequently developed HUS. Renal biopsy showed characteristic lesion of thrombotic microangiopathy and extensive cortical necrosis. She was managed with peritoneal dialysis but did not improve and developed severe sepsis due to staphylococcal peritonitis, resulting in the death of the patient. Streptococcus pneumoniae-induced HUS is uncommon, but results in severe disease in the young. There is a high risk of these patients developing end-stage kidney disease in the long term.

Patients' Perspectives on the Prevention and Treatment of Peritonitis in Peritoneal Dialysis: A Semi-Structured Interview Study.

Science.gov (United States)

Campbell, Denise J; Craig, Jonathan C; Mudge, David W; Brown, Fiona G; Wong, Germaine; Tong, Allison

♦ BACKGROUND: Peritoneal dialysis (PD) is recommended for adults with residual kidney function and without significant comorbidities. However, peritonitis is a serious and common complication that is associated with hospitalization, pain, catheter loss, and death. This study aims to describe the beliefs, needs, and experiences of PD patients about peritonitis, to inform the training, support, and care of these patients. ♦ METHODS: Qualitative semi-structured interviews were conducted with 29 patients from 3 renal units in Australia who had previous or current experience of PD. The interviews were conducted between November 2014 and November 2015. Transcripts were analyzed thematically. ♦ RESULTS: We identified 4 themes: constant vigilance for prevention (conscious of vulnerability, sharing responsibility with family, demanding attention to detail, ambiguity of detecting infection, ineradicable inhabitation, jeopardizing PD success); invading harm (life-threatening, wreaking internal damage, debilitating pain, losing control and dignity); incapacitating lifestyle interference (financial strain, isolation and separation, exacerbating burden on family); and exasperation with hospitalization (dread of hospital admission, exposure to infection, gruelling follow-up schedule, exposure to harm). ♦ CONCLUSIONS: Patients perceived that peritonitis could threaten their health, treatment modality, and lifestyle, which motivated vigilance and attention to hygiene. They felt a loss of control due to debilitating symptoms including pain and having to be hospitalized, and they were uncertain about how to monitor for signs of peritonitis. Providing patients with education about the causes and signs of peritonitis and addressing their concerns about lifestyle impact, financial impact, hospitalization, and peritonitis-related anxieties may improve treatment satisfaction and outcomes for patients requiring PD.

We administered pyrazinamide (PZA) and probenecid (PB) --two well-known modulators of urate transport via the proximal tubules - to evaluate their impact on urate transport through the peritoneal membrane and to clarify mechanisms affecting peritoneal transport. A continuous ambulatory peritoneal dialysis (CAPD) unit in 2nd Hospital of IKA (Social Services Institute), Greece. In 20 stable CAPD patients, on the study day, a 4-hour, 2-L, 1.36% glucose exchange was performed (control exchange). Pyrazinamide 3 g was given orally and another identical exchange was performed (study exchange). The same protocol was repeated with 2 g PB. KtN, peritoneal clearances of urea, creatinine, and urate for each exchange, and mass transfer area coefficients (MTAC) for the three solutes and their dialysate-to-plasma concentration (D/P) ratios were used to estimate peritoneal transport. Administration of PZA resulted in decreased clearances and MTAC values for the three solutes. The D/P ratio decreased significantly only for urate, indicating a more intense influence of PZA on urate. After PB administration, clearances of urea, creatinine, and urate were increased. MTAC and DIP ratio increased significantly only for urate (p rates.

Encapsulating peritoneal sclerosis in a peritoneal dialysis patient with prune-belly syndrome: a case report.

Science.gov (United States)

Geurts, N; Hubens, G; Wojciechowski, M; Vaneerdeweg, W

2010-01-01

This case describes a prune-belly syndrome patient who had a kidney transplantation and was diagnosed with Encapsulating Peritoneal Sclerosis (EPS), a rare but potentially fatal condition, mostly associated with Peritoneal Dialysis (PD). The definition of EPS is based on the clinical findings linked to bowel obstruction and on the demonstration of peritoneal thickening. Surgical treatment is the only established basic treatment for the condition. Prune-belly syndrome is characterized by the triad of deficient abdominal musculature, urinary tract abnormality and cryptorchidism. Because it is often associated with end-stage renal disease, PD is essential in the treatment of patients with prune-belly syndrome. The aetiology of EPS follows a 'two-hit theory': the first 'hit' is peritoneal deterioration, caused by long-time exposure to PD. This causes peritoneal disruption which predisposes the patient to a second hit. In our patient, PD discontinuation and renal transplantation are possible 'second hits' that triggered the development of EPS. This case of prune-belly syndrome has all the necessary elements for the development of EPS, and we felt we should report it as the peroperative diagnosis was unexpected.

The suggested elements in the development of a programme for severe accident management have been identified and discussed. The strategies concentrate on the two tiered approaches. Operative management utilizes the plant's equipment and operators capabilities. The recovery managment concevtrates on preserving the containment, or delaying its failure, inhibiting the release, and on strategies once there has been a release. The inspiration for this paper was an excellent overview report on perspectives on managing severe accidents in commercial nuclear power plants and extending plant operating procedures into the severe accident regime; and by the most recent publication of the International Nuclear Safety Advisory Group (INSAG) considering the question of risk reduction and source term reduction through accident prevention, management and mitigation. The latter document concludes that 'active development of accident management measures by plant personnel can lead to very large reductions in source terms and risk', and goes further in considering and formulating the key issue: 'The most fruitful path to follow in reducing risk even further is through the planning of accident management.'

Full Text Available Peritonitis is one of the most important causes of treatment failure in peritoneal dialysis (PD patients. This study describes changes in characteristics of causative organisms in PD-related peritonitis and antimicrobial susceptibility.In this single center study we analyzed retrospective 487 susceptibility profiles of the peritoneal fluid cultures of 351 adult patients with peritonitis from 1979 to 2014 (divided into three time periods, P1-P3.Staphylococcus aureus decreased from P1 compared to P2 and P3 (P<0.05 and P<0.01, respectively. Methicillin-resistant S. aureus (MRSA occurred only in P3. Methicillin-resistant Staphylococcus epidermidis (MRSE increased in P3 over P1 and P2 (P <0.0001, respectively. In P2 and P3, vancomycin resistant enterococci were detected. The percentage of gram-negative organisms remained unchanged. Third generation cephalosporin resistant gram-negative rods (3GCR-GN were found exclusively in P3. Cefazolin-susceptible gram-positive organisms decreased over the three decades (93% in P1, 75% in P2 and 58% in P3, P<0.01, P<0.05 and P<0.0001, respectively. Vancomycin susceptibility decreased and gentamicin susceptibility in gram-negatives was 94% in P1, 82% in P2 and 90% in P3. Ceftazidim susceptibility was 84% in P2 and 93% in P3.Peritonitis caused by MSSA decreased, but peritonitis caused by MRSE increased. MRSA peritonitis is still rare. Peritonitis caused by 3GCR-GN is increasing. An initial antibiotic treatment protocol should be adopted for PD patients to provide continuous surveillance.

Most investigators agree that endometriosis is associated with a state of subclinical, non-infectious peritoneal inflammation. The objective of the study was to assess concentrations of two markers of the acute inflammatory phase proteins, haptoglobin and ceruloplasmin, in peritoneal fluid of endometriotic women. 229 women who underwent diagnostic or therapeutic laparoscopy were included in the study Minimal, mild, moderate and severe endometriosis according to ASRM was confirmed in 119 women (study groups), whereas 110 patients suffered from simple serous or dermoid ovarian cysts (reference groups). Haptoglobin and ceruloplasmin concentrations in the peritoneal fluid samples aspirated during laparoscopy were measured using commercially available radial immunodiffusion kits. The concentration of haptoglobin in the peritoneal fluid of women with endometriosis was significantly higher as compared to patients with serous and dermoid ovarian cysts. Significantly higher haptoglobin level was observed in patients with severe and moderate endometriosis as compared to women from both reference groups. No significant difference in the peritoneal fluid ceruloplasmin levels was found between patients with endometriosis and women from reference groups. However, it was noted that ceruloplasmin levels are higher in the subgroup of patients with severe endometriosis as compared to both reference groups and women with mild disease. Our results support the hypothesis that endometriosis is associated with subclinical inflammation within the peritoneal cavity It may be speculated that pro-inflammatory stimuli strong enough to cause an increase in acute inflammatory phase proteins peritoneal fluid concentrations are observed only in the advanced stages of the disease.

Although peritoneal lavage with povidone-iodine (PVPI) is frequently performed after surgery on the gastrointestinal tract, the effects of PVPI on the intestinal epithelial barrier are unknown. The purpose of this study was to investigate the effects of abdominal irrigation with PVPI on the intestinal epithelial barrier in a colorectal cancer (CRC)-induced rat model. The CRC model was induced in rats with azoxymethane and dextran sodium sulfate. Next, a total of 24 male CRC-induced rats were randomly divided into three groups (n = 8): (1) a sham-operated group, (2) an NS group (peritoneal lavage 0.9% NaCl), and (3) a PVPI group (peritoneal lavage with 0.45%-0.55% PVPI). The mean arterial pressure was continuously monitored throughout the experiment. The levels of plasma endotoxin and D-lactate, blood gases, and protein concentration were measured. The ultrastructural changes of the epithelial tight junctions were observed by transmission electron microscopy. The mean arterial pressure after peritoneal lavage was lower in the PVPI group than that in the NS group. The protein concentration and levels of endotoxin and D-lactate were higher in the PVPI group than they were in the PVPI group. In addition, PVPI treatment resulted in a markedly severe metabolic acidosis and intestinal mucosal injury compared with NS rats. Peritoneal lavage with PVPI dramatically compromises the integrity of the intestinal mucosa barrier and causes endotoxin shock in CRC rats. It is unsafe for clinical applications to include peritoneal lavage with PVPI in colorectal operations. Copyright © 2018 Elsevier Inc. All rights reserved.

The peritoneum is a frequent site of involvement by peritoneal tuberculosis. Generally, computed tomography appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis. The computed tomography findings can help in the diagnosis of peritoneal tuberculosis, that is confirmed by a positive culture or hystologic analysis of biopsy obtained through laparoscopic examination. Peritoneal carcinomatosis is the main differential diagnosis. In this article we present the spectrum of tomographic manifestation of peritoneal tuberculosis and how we can differentiate it from peritoneal carcinomatosis. (author)

Few diagnostic biomarkers for sepsis after emergency peritonitis surgery are available to clinicians, and, thus, it is important to develop new biomarkers for patients undergoing this procedure. We investigated whether serum glutamine and selenium levels could be diagnostic biomarkers of sepsis in individuals recovering from emergency peritonitis surgery. From February 2012 to March 2013, patients who had peritonitis diagnosed at the emergency department and underwent emergency surgery were screened for eligibility. Serum glutamine and selenium levels were obtained at pre-operative, post-operative and recovery time points. The average level of pre-operation serum glutamine was significantly different from that on the recovery day (0.317 ± 0.168 vs. 0.532 ± 0.155 mM, P peritonitis. We recommend including glutamine as a biomarker for sepsis severity assessment in addition to the commonly used clinical indicators.

The surgical management of left colonic emergencies has evolved in the past few decades. Recently, there has been increasing interest in resection with primary anastomosis in selected cases. The aim of this study was to evaluate the differences in outcome in patients with peritonitis or obstruction treated by resection, on-table lavage and primary anastomosis of the left colon. Between January 1992 and August 1995, 212 patients underwent emergency operation for a distal colonic lesion: 97 presented with peritonitis, 113 with obstruction and two with other indications. Intraoperative colonic lavage was performed in 37 patients with obstruction and in 24 with an acute intra-abdominal inflammatory process. The postoperative mortality rate was 5 per cent. The incidence of clinical anastomotic leakage was 5 per cent. Wound infection was observed in ten patients (16 per cent), more often in those with peritonitis (P = 0.03). The overall mean(s.d.) hospital stay was 15(9) days. Resection, on-table lavage and primary anastomosis constitute the operation of choice for selected patients with left colonic emergency.

The aim of this study is to evaluate the usefulness of diffusion-weighted (DW) magnetic resonance (MR) imaging in detecting peritoneal dissemination in cases of gynecological malignancy. We retrospectively analyzed MR images obtained from 26 consecutive patients with gynecological malignancy. Peritoneal dissemination was histologically diagnosed in 15 of the 26 patients after surgery. We obtained DW images and half-Fourier single-shot turbo-spin-echo images in the abdomen and pelvis, and then generated fusion images. Coronal maximum-intensity-projection images were reconstructed from the axial source images. Reader interpretations were compared with the laparotomy findings in the surgical records. Receiver-operating characteristic (ROC) curves were used to represent the presence of peritoneal dissemination. In addition, the sensitivity and specificity were calculated. DW imaging depicted the tumors in 14 of 15 patients with peritoneal dissemination as abnormal signal intensity. ROC analysis yielded Az values of 0.974 and 0.932 for the two reviewers. The mean sensitivity and specificity were 90 and 95.5%. DW imaging plays an important role in the diagnosis and therapeutic management of patients with gynecological malignancy. (orig.)

Therefore, the monitoring and estimation of peritoneal function are important in PD patients. Oxidative stress has been implicated as one possible mechanism of peritoneal membrane damage. The aim of this study was to evaluate the association between an oxidative stress marker, 8-hydroxydeoxyguanosine (8-OHdG, and peritoneal damage in PD patients.Methods: The authors evaluated 8-OHdG in drained dialysate by enzyme immunoassay to investigate the association between 8-OHdG and solute transport rate estimated by peritoneal equilibration test and matrix metalloproteinase-2 (MMP-2 level in 45 samples from 28 PD patients.Results: The 8-OHdG level was significantly correlated with dialysate:plasma creatine ratio (r = 0.463, P < 0.05 and significantly inversely correlated with D/D0 glucose (where D is the glucose level of peritoneal effluents obtained 4 hours after the injection and D0 is the glucose level obtained immediately after the injection (r = -0.474, P < 0.05. The 8-OHdG level was also significantly correlated with MMP-2 level (r = 0.551, P < 0.05, but it was not correlated with the age of subjects, the duration of PD, or blood pressure.Conclusion: The level of 8-OHdG in drained dialysate may be a useful novel marker of peritoneal damage in PD.Keywords: oxidative stress, solute transport rate, MMP-2, peritoneal equilibration test

Sclerosing encapsulating peritonitis (SEP) is a serious complication of peritoneal dialysis (PD) characterized by thickened peritoneal membranes, which lead to decreased ultra-filtration and intestinal obstruction. Its early clinical features are nonspecific, and it is often diagnosed late following laparotomy and peritoneal biopsy, when the patient develops small bowel obstruction, which can be a life-threatening complication. However, this is changing with increasing awareness of computed tomography (CT) findings in SEP. CT can yield an early, non-invasive diagnosis that may improve patient outcome. We present a review of the CT appearances of SEP

To review the current literature on educational interventions used in peritoneal dialysis (PD). Educational interventions have become increasingly relevant because they play a key role in helping individuals to actively participate in their therapy and to manage their chronic condition. The paper will focus on two areas: (a) educational interventions for individuals living with PD and (b) educational interventions for PD nurses. A narrative review of primary research. Electronic searches of the MEDLINE, CINAHL, EMBASE, ERIC and Cochrane Library (2006-2013) databases were undertaken using terms such as peritoneal dialysis, insertive training, curriculum, nursing education, train the trainer, coach the coach, tutor the tutor, and patient education were used. All studies were reviewed by two researchers. Titles and abstracts of 555 studies were screened and read. Full text articles retrieved were further screened against the inclusion and exclusion criteria. Relevant data on the educational interventions for people receiving PD and nurse training programs were extracted and synthesized narratively. Eighteen articles met the inclusion criteria. Most of them focused on educational intervention programs for people undergoing PD. Findings on the link between the PD trainer's background and peritonitis rates among individuals undergoing PD are inconsistent. PD learners should be taught self-management skills as well as technical skills. They might also benefit from receiving decision-making aids. Older people, people with co-morbidities and people with low educational status need more time to acquire self-care skills and are more likely to develop peritonitis. Home visits have the potential to improve learning outcomes. Re-training needs should be assessed and fulfilled as appropriate. Case and disease management programs have been shown to have positive outcomes for individuals receiving PD. Educational interventions for PD remain an under-researched area, despite the

Proinflammatory and prooxidative environment in the peritoneal cavity may be involved in the pathogenesis of endometriosis. Imbalance between reactive oxygen species levels and the antioxidant capacity leads to oxidation of low-density lipoproteins (LDL). The importance of oxidized LDL (Ox-LDL) in the development of atherosclerosis is well recognized. The aim of our study was to evaluate for the presence of ox-LDL in the peritoneal fluid (PF) of women with and without endometriosis. A total of 60 women who underwent laparoscopy were divided into groups: endometriosis sufferers with minimal to mild (n 20) and moderate to severe (n 20) stages, and the reference group (n 20) with functional follicle ovarian cysts. Oxidized LDL levels were determined in the PF using enzyme immunoassay Oxidized LDL levels were detectable in all peritoneal fluid samples. Significantly increased levels of ox-LDL were observed in PF of women with stage III/IV endometriosis compared to the reference group (p = 0.03). However peritoneal fluid ox-LDL concentrations did not differ significantly between patients with minimal/mild and women with moderate/severe stage of the disease (p = 0.2). No significant difference in the PF ox-LDL concentrations was also found between women with stage I/II endometriosis and patients with follicle cysts (p = 0.3). Increased peritoneal fluid ox-LDL levels observed in women with advanced-stage endometriosis suggest the important role of oxidative stress in the pathogenesis of the disease.

2014-01-01

Full Text Available Fungal peritonitis (FP is a rare, but serious complication of peritoneal dialysis. We analyzed the incidence of FP, associated risk factors and outcome of patients with FP and evaluated the role of prophylactic antifungal agent in reducing its incidence. We studied all patients with FP from January 2005 to January 2012. Study period was divided into two parts, period I (January 2005 to January 2010, when prophylactic antifungal was not used and period II (January 2010 to January 2012, when prophylactic antifungal (fluconazole was used. A total of 142 episodes of peritonitis were documented during this period of which 20 (14% were FP. During the study period I, 18 of 102 episodes of peritonitis (17.6% and in the study period II (with antifungal prophylaxis, only 2 of 40 episodes of peritonitis (5% were due to fungal infection (P = 0.04. Nine out of 20 patients (45% had prior exposure to antibiotics. Fungal isolates were Candida albicans in 65%, non-albicans Candida in 25%, Rhizopus species in 5% and Alternaria in 5% of the patients. While 12 out of 20 patients (60% recovered completely and were re-initiated on continuous ambulatory peritoneal dialysis (CAPD, 4 of them expired (20% and 4 others (20% were shifted to hemodialysis. Use of prophylactic antifungal agent significantly reduced the incidence of FP (P = 0.04. We conclude that - fluconazole when used as a prophylactic agent in the setting of bacterial peritonitis significantly reduces the incidence of subsequent FP in CAPD patients.

Aim: To evaluate the computed tomography (CT) signs of encapsulating peritoneal sclerosis (EPS) in patients on peritoneal dialysis (PD) as predictive factors for the evolution to abdominal cocoon (AC). Materials and methods: Clinical features and CT signs of 90 patients on PD were retrospectively reviewed. According to the clinical features, they were divided into three groups (asymptomatic, moderate, or severe). Clinical results were correlated with previously reported CT signs of EPS, i.e., peritoneal thickening, peritoneal calcifications, loculated fluids, small bowel faeces sign, small bowel obstruction, clustered bowel loops, pseudo sac, signs of bowel ischaemia or necrosis. AC was defined at CT by the association of clustered bowel loops and a pseudo sac. Statistical analysis was performed using the Fisher's exact test and the t-test. Results: Although demonstrated in symptomatic patients (p = 0.041), the occurrence of AC was not correlated with the severity of the symptoms (p = 0.16). Among the CT signs, the presence of loculated fluids (p = 0.011), a small bowel faeces sign (p = 0.002); and small bowel obstruction (p = 0.0001) were found to be statistically correlated with the appearance of an AC. Moreover, the association of loculated fluids, small bowel faeces sign, small bowel obstruction was extremely sensitive and specific in the development of AC (sensitivity = 67%, specifity = 100%, positive predictive value = 100%, negative predictive value = 96%). Conclusion: CT should be carried out in every symptomatic patient on PD. Indeed, the association of loculated fluid, small bowel faeces sign, and small bowel obstruction enables the prediction of the development of AC, which is likely to curtail PD and require surgery.

Sclerosing peritonitis already has been described as a serious complication of the continuous ambulatory peritoneal dialysis. But different other affections of the pertioneum such as chronic bacterial peritonitis and pancreatitis may result in sclerosing peritonitis, too. The symptom is characterised by thickened small bowel walls and periotoneal membranes as well as peritoneal calcifications which can be shown in computed tomography. We demonstrate two cases of peritoneal ossifications due to peritonitis and pancreatitis. (orig.)

♦ Chronic renal failure and aging are suggested as risk factors for cognitive impairment (CI). We studied the prevalence of CI among peritoneal dialysis (PD) patients using Montreal Cognitive Assessment (MoCA), its impact on PD-related peritonitis in the first year, and the potential role of assisted PD. ♦ One hundred fourteen patients were newly started on PD between February 2011 and July 2013. Montreal Cognitive Assessment was performed in the absence of acute illness. Data on patient characteristics including demographics, comorbidities, blood parameters, dialysis adequacy, presence of helpers, medications, and the number PD-related infections were collected. ♦ The age of studied patients was 59±15.0 years, and 47% were female. The prevalence of CI was 28.9%. Patients older than 65 years old (odds ratio [OR] 4.88, confidence interval [CI] 1.79 - 13.28 p = 0.002) and with an education of primary level or below (OR 4.08, CI 1.30 - 12.81, p = 0.016) were independent risk factors for CI in multivariate analysis. Patients with PD-related peritonitis were significantly older (p peritonitis among self-care PD patients (OR 2.20, CI 0.65 - 7.44, p = 0.20). When we compared patients with MoCA-defined CI receiving self-care and assisted PD, there were no statistically significant differences between the 2 groups in terms of age, MoCA scores, or comorbidities. There were also no statistically significant differences in 1-year outcome of PD-related peritonitis rates or exit-site infections. ♦ Cognitive impairment is common among local PD patients. Even with CI, peritonitis rate in self-care PD with adequate training is similar to CI patients on assisted PD. Copyright © 2016 International Society for Peritoneal Dialysis.

We used a microarray approach to examine changes in gene expression in turbot peritoneal cells after injection of the fish with vaccines containing the ciliate parasite Philasterides dicentrarchi as antigen and one of the following adjuvants: chitosan-PVMMA microspheres, Freund́s complete adjuvant, aluminium hydroxide gel or Matrix-Q (Isconova, Sweden). We identified 374 genes that were differentially expressed in all groups of fish. Forty-two genes related to tight junctions and focal adhesions and/or actin cytoskeleton were differentially expressed in free peritoneal cells. The profound changes in gene expression related to cell adherence and cytoskeleton may be associated with cell migration and also with the formation of cell-vaccine masses and their attachment to the peritoneal wall. Thirty-five genes related to apoptosis were differentially expressed. Although most of the proteins coded by these genes have a proapoptotic effect, others are antiapoptotic, indicating that both types of signals occur in peritoneal leukocytes of vaccinated fish. Interestingly, many of the genes related to lymphocytes and lymphocyte activity were downregulated in the groups injected with vaccine. We also observed decreased expression of genes related to antigen presentation, suggesting that macrophages (which were abundant in the peritoneal cavity after vaccination) did not express these during the early inflammatory response in the peritoneal cavity. Finally, several genes that participate in the inflammatory response were differentially expressed, and most participated in resolution of inflammation, indicating that an M2 macrophage response is generated in the peritoneal cavity of fish one day post vaccination.

♦ Research indicates that the socioeconomic status (SES) of individuals and the area where they live are related to initial peritonitis and outcomes in peritoneal dialysis (PD). We conducted a retrospective, multi-center cohort study in China to examine these associations. ♦ Data on 2,171 PD patients were collected from 7 centers, including baseline demographic, socioeconomic, and laboratory data. We explored the potential risk factors for initial peritonitis and outcomes using univariate Cox regression and unadjusted binary logistic regression. Then, we used propensity score matching to balance statistically significant risk factors for initial peritonitis and outcomes, and Kaplan-Meier survival analysis to compare differences in peritonitis-free rates between different groups of participants after matching. ♦ A total of 563 (25.9%) initial episodes of peritonitis occurred during the study period. The Kaplan-Meier peritonitis-free rate curve showed high-income patients had a significantly lower risk than low-income patients (p = 0.007) after matching for age, hemoglobin, albumin, and regional SES and PD center. The risk of treatment failure was significantly lower in the high-income than the low-income group after matching for the organism causing peritonitis and PD center: odds ratio (OR) = 0.27 (0.09 - 0.80, p = 0.018). Regional SES and education were not associated with initial peritonitis and outcomes. ♦ Our study demonstrates low individual income is a risk factor for the initial onset of peritonitis and treatment failure after initial peritonitis.

Candida peritonitis is reported in people and is associated with significant morbidity and mortality compared with sterile or bacterial peritonitis. Recognized predisposing risk factors include peritoneal dialysis, hollow viscous organ perforation, abdominal surgery, inflamed intestinal mucosa, antimicrobial administration, and immunosuppression. In this report, we describe 5 cases of dogs with peritonitis complicated by Candida spp; 3 dogs with C albicans, one dog with C albicans and C glabrata, and one dog with C glabrata only. The 3 dogs with C albicans peritonitis presented with duodenal perforation due to NSAID therapy, intestinal resection and anastomosis following postspay-surgery dehiscence, and intestinal foreign body removal. The 2 dogs with C glabrata peritonitis had undergone cholecystectomy due to gall bladder rupture and dehiscence of intestinal biopsy removal sites following exploratory laparatomy. In all cases, initial diagnosis of fungal peritonitis was made via cytologic examination of peritoneal effusions, which revealed marked pyogranulomatous inflammation with numerous 3-8 μm oval, deeply basophilic yeast organisms with thin clear capsules noted within phagocytes and extracellularly. In addition, germ tube formation, hyphae, and pseudohyphae were rarely seen in some of the cases with pure C albicans. Identity of the organisms was determined by culture in all cases and confirmed by PCR in 3 cases. Candida spp. are commensals normally inhabiting the alimentary, the upper respiratory, and the lower urogenital tracts of mammals. They are opportunistic pathogens that can invade and colonize tissue when a patient is immune-compromised or there is disruption of the mucosal barrier. Candida peritonitis should be considered in patients with peritoneal contamination with gastrointestinal or biliary contents. © 2013 American Society for Veterinary Clinical Pathology.

♦ Background: Peritoneal dialysis (PD) is an established treatment modality for end-stage renal disease (ESRD). Peritonitis remains a serious complication in PD patients and an important cause of drop-out from the program. Types of pathogens and their drug resistance patterns may determine the outcome of peritonitis. The present study was undertaken to determine the microbiology of peritonitis in PD patients, antibiotic resistance in commonly isolated bacterial pathogens and clinical outcomes. ♦ Method: We enrolled 211 patients with ESRD undergoing PD who developed peritonitis during 2002 to 2011. PD fluids were cultured and antibiotic susceptibility test of the bacterial isolates was performed. ♦ Result: A total of 303 peritonitis episodes with an overall incidence of 0.41 episodes per patient-year were recorded. Gram-positive, gram-negative, fungi, Mycobacterium tuberculosis and ≥ 2 organisms were isolated from 102 (33.7%), 89 (29.4%), 41 (13.5%), 11 (3.6%) and five (1.6%) episodes respectively; 55 (18.2%) episodes were culture negative. Coagulase-negative Staphylococcus spp. (CONS) was the most common isolate. Catheter loss and hospital admission in gram-negative peritonitis were significantly higher than in gram-positive peritonitis (36/89 (40.4%) vs 20/102 (19.6%), p peritonitis due to vancomycin-resistant enterococci, ESBL- and MBL-producing bacteria. ♦ Conclusion: Emerging antimicrobial resistance calls for prompt diagnosis and aggressive empiric therapy based on the local sensitivity data.

2010-11-01

Full Text Available Abstract Introduction Acute hydrothorax is an uncommon but a well-recognized complication of peritoneal dialysis. No single test is definitive for diagnosis. Although it is not a life-threatening condition, hydrothorax often requires abandonment of peritoneal dialysis. Delay in diagnosis can lead to worsening of the clinical status. Case Presentation A 33-year-old Caucasian woman with lupus, who was successfully treated with temporary peritoneal dialysis 17 years previously, presented with acute dyspnea and a right pleural effusion after recommencing peritoneal dialysis. Investigations eliminated infective, cardiac, and primary respiratory causes. Peritoneal dialysis-related hydrothorax was suggested by biochemistry, and a pleuroperitoneal leak was definitively confirmed by using a Tc-99 m DTPA (diethylene triamine penta-acetic acid scintigraphy scan. Subsequently, she underwent video-assisted thoracoscopy-guided talc pleurodesis and was able to return successfully to peritoneal dialysis. Conclusion Although our case is not the first report that describes the occurrence of acute hydrothorax in peritoneal dialysis, it is an important condition to recognize for the wider general medical community. Furthermore, this case demonstrates that peritoneal dialysis can be continued with a hydrothorax, provided the underlying cause can be corrected. We review the literature pertaining to the utility and reliability of different diagnostic approaches to hydrothorax.

Peritoneal catheters are mainly used for peritoneal dialysis in patients with end-stage renal disease. Other uses of this catheter include intraperitoneal chemotherapy and gene therapy for ovarian cancer and draining of uncontrolled refractory ascites in patients with liver cirrhosis. Traditionally, surgeons place most of these peritoneal catheters either by laparoscopy or open laparotomy. We detail our percutaneous approach to placing peritoneal catheters using fluoroscopic guidance. We emphasize the use of additional ultrasound guidance, including gray scale and color Doppler ultrasound, to determine the safest puncture site and to guide the initial needle puncture in order to avoid bowel perforation and injury to epigastric artery. We present our experience in placing peritoneal catheters using this technique in 95 patients with various indications. Fluoroscopic guided percutaneous placement of peritoneal catheters is a safe, minimally invasive, and effective alternative to open surgical or laparoscopic placement.

Full Text Available Abstract Background Peritoneal dialysis (PD is the preferred dialysis modality in children. Its major drawback is the limited technique survival due to infections and progressive ultrafiltration failure. Conventional PD solutions exert marked acute and chronic toxicity to local tissues. Prolonged exposure is associated with severe histopathological alterations including vasculopathy, neoangiogenesis, submesothelial fibrosis and a gradual loss of the mesothelial cell layer. Recently, more biocompatible PD solutions containing reduced amounts of toxic glucose degradation products (GDPs and buffered at neutral pH have been introduced into clinical practice. These solutions contain lactate, bicarbonate or a combination of both as buffer substance. Increasing evidence from clinical trials in adults and children suggests that the new PD fluids may allow for better long-term preservation of peritoneal morphology and function. However, the relative importance of the buffer in neutral-pH, low-GDP fluids is still unclear. In vitro, lactate is cytotoxic and vasoactive at the concentrations used in PD fluids.

The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis. Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse. Qualitative design formed by thematic qualitative text analysis. Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application. The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses. The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess. Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy. © 2016 John Wiley & Sons

Full Text Available Background: The management of ascites can be problematic. This is especially true in patients with diuretic refractory ascites who develop a tense abdomen. This often results in hypotension and decreased venous return with resulting renal failure. In this paper, we further examine the risks and benefits of utilizing an indwelling peritoneal catheter to remove large-volume ascites over a 72-h period while maintaining intravascular volume and preventing renal failure. Methods: We retrospectively reviewed charts and identified 36 consecutive patients undergoing continuous large-volume paracentesis with an indwelling peritoneal catheter. At the time of drain placement, no patients had signs or laboratory parameters suggestive of spontaneous bacterial peritonitis. The patients underwent ascitic fluid removal through an indwelling peritoneal catheter and were supported with scheduled albumin throughout the duration. The catheter was used to remove up to 3 L every 8 h for a maximum of 72 h. Regular laboratory and ascitic fluid testing was performed. All patients had a clinical follow-up within 3 months after the drain placement. Results: An average of 16.5 L was removed over the 72-h time frame of indwelling peritoneal catheter maintenance. The albumin infusion utilized correlated to 12 mg/L removed. The average creatinine trend improved in a statistically significant manner from 1.37 on the day of admission to 1.21 on the day of drain removal. No patients developed renal failure during the hospital course. There were no documented episodes of neutrocytic ascites or bacterial peritonitis throughout the study review. Conclusion: Large-volume peritoneal drainage with an indwelling peritoneal catheter is safe and effective for patients with tense ascites. Concomitant albumin infusion allows for maintenance of renal function, and no increase in infectious complications was noted.

Full text: Among various conservative treatment modalities for end stage renal disease (ESRD), continuous ambulatory peritoneal dialysis (CAPD) is increasingly being used in many centers. The success of CAPD depends largely on the permeable characteristics of the peritoneal membrane. Peritoneal Equilibration Test (PET), first described by Twardowski in 1987, is the most commonly used method for determination of peritoneal membrane characteristics. However, this test has several limitations. In order to find an alternative method for assessing peritoneal membrane characteristics we undertook this prospective study involving 20 patients. The main objective was to determine whether peritoneal excretion of intravenously applied Tc-99m-DTPA can be used for this purpose. 20 patients undergoing regular CAPD were included in this study. 370 MBq (10 mCi) of Tc-99m-DTPA was injected intravenously in the same standard preconditions as for the PET evaluation. A standard dose of 370 MBq (10 mCi) DTPA was kept and used later for calculations. At the end of 4 hours, a dialysate fluid sample was collected and the total dialysis effluent volume was measured. Excretion of Tc-99m-DTPA into the dialysate fluid as percentage of injected dose was calculated. Simultaneously standard PET values were determined. The peritoneal excretion of Tc-99m-DTPA ranged from 8 to 16 % of the injected dose depending upon the peritoneal membrane permeability. The patients were divided into following four groups depending upon DTPA excretion. High transporters (15 % and above); high average(12-15 %); low average (10-12 %); low transporters (10 % and less). When the results were compared with standard PET values, a good correlation could be established. We conclude that the radioisotope method using Tc-99m-DTPA can a good alternative technique to assess peritoneal membrane permeability. (author)

The effects of living distantly from peritoneal dialysis units on peritonitis risk, microbiology, treatment and outcomes: a multi-centre registry study

Science.gov (United States)

2012-01-01

Background The aim of the study was to determine whether distance between residence and peritoneal dialysis (PD) unit influenced peritonitis occurrence, microbiology, treatment and outcomes. Methods The study included all patients receiving PD between 1/10/2003 and 31/12/2008, using ANZDATA Registry data. Results 365 (6%) patients lived ≥100 km from their nearest PD unit (distant group), while 6183 (94%) lived peritonitis in distant patients (1.34 years, 95% CI 1.07-1.61) was significantly shorter than in local patients (1.68 years, 95% CI 1.59-1.77, p = 0.001), whilst overall peritonitis rates were higher in distant patients (incidence rate ratio 1.32, 95% CI 1.20-1.46). Living ≥100 km away from a PD unit was independently associated with a higher risk of S. aureus peritonitis (adjusted odds ratio [OR] 1.64, 95% CI 1.09-2.47). Distant patients with first peritonitis episodes were less likely to be hospitalised (64% vs 73%, p = 0.008) and receive antifungal prophylaxis (4% vs 10%, p = 0.01), but more likely to receive vancomycin-based antibiotic regimens (52% vs 42%, p peritonitis outcomes, distant patients were more likely to be cured with antibiotics alone (OR 1.55, 95% CI 1.03-2.24). All other outcomes were comparable between the two groups. Conclusions Living ≥100 km away from a PD unit was associated with increased risk of S. aureus peritonitis, modified approaches to peritonitis treatment and peritonitis outcomes that were comparable to, or better than patients living closer to a PD unit. Staphylococcal decolonisation should receive particular consideration in remote living patients. PMID:22702659

Peritoneal dialysis is a new renal replacement therapy recently introduced in Morocco since 2006. Continuous ambulatory peritoneal dialysis has proven to be as effective as hemodialysis. However, it is associated with several complications. The aim of this study was to evaluate the outcome of complications in patients treated with peritoneal dialysis at our center. The nature of non-infectious complications was noted during follow-up in these patients. Fiftyseven complications were noted among 34 patients between June 2006 and June 2014. Catheter migration was the most common complication (36.8%), followed by obstruction (14%), dialysate leaks (14%), hemorrhagic complications (10.5%) and, finally, hernia (12.2%), catheter perforation (5.2%) and externalization (3.5%).

Full Text Available We present a case report of a 47-year-old woman who was admitted to our University-Hospital following diagnosis of pelvic mass. Abdominal examination revealed a tender, palpable mass on the right iliac region. At the gynecological examination uterus was regular in size. On the left side of the uterus a mass of 9 cm was observed; its surface was irregular and no mobility was found. Abdominal CT and NMR revealed massive ascites, omental cake and increased volume of both ovaries. Patient underwent longitudinal suprombelical-pubic laparotomy. After opening abdominal cavity, a free-fluid sample was taken and the results were positive for malignant cells. Typical neoplastic localizations on both ovaries, Douglas’ peritoneum, rectum, sigmoid colon and omentum were observed. Extemporaneous histological examination diagnosed a peritoneal serous papillary carcinoma. Hysterectomy with salpingo oophorectomy, total omentectomy, appendectomy, pelvic and lumbo-aortic lymphadenectomy was performed. Retroperitoneal approach to remove the whole Douglas’ peritoneum together with the pouch malignant localizations was done. Sigmoid colon and rectum were resected. A latero-terminal anastomosis with stapler was performed. All the visible abdominal maligant lesions were cut out. No transfusion was necessary. The postoperative course was regular and after seven days the patient was discharged. Chemotherapy ended the therapeutic management (six cycles of carboplatin and paclitaxel. After one year the patient is in good health and instrumental investigations (Ultrasounds, TC and NMR are negative for recurrence. Such a case is very interesting for the discrepancy between slight symptoms and severity of the disease, the solution of which was very complex requiring a skillful polyspecialized oncological team.

Th17 cells are a newly discovered T helper lymphocyte subpopulation, producing interleukin IL-17. Th17 cells are present in blood and peritoneal fluid (PF) at different stages of endometriosis. We aim to establish their potential importance in the pathogenesis and clinical features of the disease. The percentage of Th17 cells among T helper lymphocytes was determined in the PF and peripheral blood (PB) of patients with endometriosis and in the control group by flow cytometry using monoclonal antibodies: anti-CD-4-FITC, anti-CD-3-PE/Cy5, and anti-IL-17A-PE. Th17 percentage is increased in PF in comparison with PB in both endometriotic patients and in the control group. In severe endometriosis, the percentage of Th17 cells in PF was higher than with early (I/II stage) endometriosis. A positive correlation between the percentage of Th17 cells in PF and the white blood cell count in PB was found in patients with endometriosis. Targeting the activity of PF Th17 cells may have an influence on the proliferation of ectopic tissue and clinical manifestations of the disease. Copyright © 2016 Elsevier Ireland Ltd.

Studies have long sought specific cytokines that could characterize endometriosis. Either due to variations between study designs regarding the assessment criteria for the cytokine or to low power resulting from small sample size, no factor proved to be sufficiently specific to endometriosis. In other clinical fields, a combination of several markers proved to be more powerful than a single-molecule approach. As well, in the context of endometriosis, simultaneous assessment of several cytokines present in the peritoneal fluid might help in unveiling patho-physiological processes, thus contributing to a better understanding of the condition. Therefore, the objective of this study was to investigate peritoneal fluid cytokines-derived of endometriotic women. For this retrospective case-control study, peritoneal fluid samples were obtained at laparoscopy and assessed by multiplex. Our data showed distinct patterns of peritoneal fluid cytokine concentrations in endometriotic women most notably a marked increase in EGF, FGF-2, IL-1α, MIP-1β, TGFα, PDGF-AA, PDGF-BB, MCP-3, sCD40L, Gro Pan, IL-17α, MDC and Rantes. The overall effect of fertility status revealed a significant difference for only one cytokine, namely MDC. Furthermore, FLT-3L and IP-10 levels were decreased in endometriosis patients, the former in both menstrual cycle phases and the latter in the secretory phase. A significant inverse Pearson correlation (pendometriosis patients at stages III-IV and in the secretory phase. These changes may exacerbate the local peritoneal angiogenic and proliferative reaction observed in women with endometriosis, and contributes to its pathophysiology.

Introduction To evaluate the impact of serum and peritoneal levels of tumour markers on peritoneal carcinomatosis and survival in gastric adenocarcinoma. Materials and methods Patients with gastric adenocarcinoma were evaluated with regard to serum and peritoneal carcinoembryonic antigen (CEA) and CA19-9. Numeric values and groupings based on serum and peritoneal cutoff values were used. Development of peritoneal carcinomatosis, including positive washing cytology, was regarded as main outcome. Gastric cancer outcomes as disease free and overall survival were analysed. Results There were 67 patients with a mean age of 60 ± 11 years. Positive peritoneal washing cytology was significantly associated with serum CA19-9 and high serum CA 19-9 group (P = 0.033 and P = 0.011, respectively). High peritoneal CEA was shown to be significantly associated with peritoneal carcinomatosis (P = 0.032). After a median follow up of 17 months, 48 patients (71.7%) were alive. Patients with peritoneal carcinomatosis showed significant poorer prognosis as shown by overall survival rate of 28.6%. Only serum CEA was significantly associated with lower disease free and overall survival (P = 0.002 and P = 0.001, respectively). Discussion and conclusion Serum CEA is shown to be significantly associated with poor prognosis for gastric cancer patients. Serum level of CA19-9 and high peritoneal CEA levels are significant predictors for positive peritoneal washing cytology and the development of peritoneal carcinomatosis, respectively. Therefore, the possible impact of serum and peritoneal tumor markers especially on the staging and prognosis of gastric cancer remains to be clarified by future studies.

Secondary diffuse peritonitis still has a high morbidity and mortality even now; therefore, the various strategies and options for the different surgical therapies are undergoing an evidence-based review. Laparoscopic lavage without resection of the focus of sepsis for example is a profoundly different approach in the treatment of diffuse peritonitis from the damage control-based strategy of surgery with initial laparostomy and deferred anastomosis. The evidential data for minimally invasive therapy are comparatively well-reviewed for appendicitis, cholecystitis and ulcerated perforation of the stomach and duodenum. In contrast, the evidence for laparoscopy and minimally invasive surgery with lavage and deferred anastomosis or damage control in secondary peritonitis has improved but is still low and cannot yet be clearly recommended. This article presents an overview of the currently available therapeutic methods for diffuse peritonitis and a critical consideration of the evidence-based data. The key recommendation is that the decision to use a surgical procedure based on the currently available data depends more on the severity of the abdominal sepsis, the duration, the age of the patient and comorbidities than on the individual technique.

Nodular smooth muscle metaplasia in multiple peritoneal endometriosis.

Kim, Hyun-Soo; Yoon, Gun; Ha, Sang Yun; Song, Sang Yong

2015-01-01

We report here an unusual presentation of peritoneal endometriosis with smooth muscle metaplasia as multiple protruding masses on the lateral pelvic wall. Smooth muscle metaplasia is a common finding in rectovaginal endometriosis, whereas in peritoneal endometriosis, smooth muscle metaplasia is uncommon and its nodular presentation on the pelvic wall is even rarer. To the best of our knowledge, this is the first case of nodular smooth muscle metaplasia occurring in peritoneal endometriosis. As observed in this case, when performing laparoscopic surgery in order to excise malignant tumors of intra-abdominal or pelvic organs, it can be difficult for surgeons to distinguish the metastatic tumors from benign nodular pelvic wall lesions, including endometriosis, based on the gross findings only. Therefore, an intraoperative frozen section biopsy of the pelvic wall nodules should be performed to evaluate the peritoneal involvement by malignant tumors. Moreover, this report implies that peritoneal endometriosis, as well as rectovaginal endometriosis, can clinically present as nodular lesions if obvious smooth muscle metaplasia is present. The pathological investigation of smooth muscle cells in peritoneal lesions can contribute not only to the precise diagnosis but also to the structure and function of smooth muscle cells and related cells involved in the histogenesis of peritoneal endometriosis.

Peritoneal solute transport and inflammation.

Science.gov (United States)

Davies, Simon J

2014-12-01

The speed with which small solutes cross the peritoneal membrane, termed peritoneal solute transport rate (PSTR), is a key measure of individual membrane performance. PSTR can be quantified easily by using the 4-hour dialysate to plasma creatinine ratio, which, although only an approximation to the diffusive characteristics of the membrane, has been well validated clinically in terms of its relationship to patient survival and changes in longitudinal membrane function. This has led to changes in peritoneal dialysis modality use and dialysis prescription. An important determinant of PSTR is intraperitoneal inflammation, as exemplified by local interleukin 6 production, which is largely independent of systemic inflammation and its relationship to comorbid conditions and increased mortality. There is no strong evidence to support the contention that the peritoneal membrane in some individuals with high PSTR is qualitatively different at the start of treatment; rather, it represents a spectrum that is determined in part by genetic factors. Both clinical and experimental evidence support the view that persistent intraperitoneal inflammation, detected as a continuously high or increasing PSTR, may predispose the membrane to progressive fibrosis.

Uncertainties and severe-accident management

International Nuclear Information System (INIS)

Kastenberg, W.E.

1991-01-01

Severe-accident management can be defined as the use of existing and or alternative resources, systems, and actions to prevent or mitigate a core-melt accident. Together with risk management (e.g., changes in plant operation and/or addition of equipment) and emergency planning (off-site actions), accident management provides an extension of the defense-indepth safety philosophy for severe accidents. A significant number of probabilistic safety assessments have been completed, which yield the principal plant vulnerabilities, and can be categorized as (a) dominant sequences with respect to core-melt frequency, (b) dominant sequences with respect to various risk measures, (c) dominant threats that challenge safety functions, and (d) dominant threats with respect to failure of safety systems. Severe-accident management strategies can be generically classified as (a) use of alternative resources, (b) use of alternative equipment, and (c) use of alternative actions. For each sequence/threat and each combination of strategy, there may be several options available to the operator. Each strategy/option involves phenomenological and operational considerations regarding uncertainty. These include (a) uncertainty in key phenomena, (b) uncertainty in operator behavior, (c) uncertainty in system availability and behavior, and (d) uncertainty in information availability (i.e., instrumentation). This paper focuses on phenomenological uncertainties associated with severe-accident management strategies

[Residual renal function and nutritional status in patients on continuous ambulatory peritoneal dialysis].

During the last years, an increasing number of patients with end-stage renal failure caused by various underlying diseases, all over the world, is treated by renal replacement therapy. NUTRITIONAL STATUS: Malnutrition is often found in patients affected by renal failure; it is caused by reduced intake of nutritional substances due to anorexia and dietary restrictions hormonal and metabolic disorders, comorbid conditions and loss of proteins, amino-acids, and vitamins during the dialysis procedure itself. Nutritional status significantly affects the outcome of patients on chronic dialysis treatment. Recent epiodemiological trials have proved that survival on chronic continuous ambulatory peritoneal dialysis program depends more on residual renal function (RRF) than on peritoneal clearances of urea and creatinine. The aim of the study was to analyze the influence of RRF on common biochemical and anthropometric markers of nutrition in 32 patients with end-stage renal failure with various underlying diseases during the first 6 months on continuous ambulatory peritoneal dialysis (CAPD). The mean residual creatinine clearance was 8,3 ml/min and the mean RRF was 16,24 l/week in our patients at the beginning of the chronic peritoneal dialysis treatment. During the follow-up, the RRF slightly decreased, while the nutritional status of patients significantly improved. Gender and age, as well as the leading disease and peritonitis didn't influence the RRF during the first 6 months of CAPD treatment. We found several positive correlations between RRF and laboratory and anthropometric markers of nutrition during the follow-up, proving the positive influence of RRF on nutritional status of patients on chronic peritoneal dialysis.

Ultrasonography was performed prospectively in 20 patients who were undergoing continuous ambullatory peritoneal dialysis for evaluation of complications. We examined the abdominal wall along the course of catheter and the peritoneal cavity with special attention to the dialysate distribution, dialysate echogenecity, thickness of the peritoneum small bowel distribution and the position of the catheter tip. Peritonitis was the most common complication (n=7); sonographic findings were small bowel adhesion (n=5) multiseptated ascites(n=1), peritoneal thickening(n=4), and tunnel infection(n=1) and exith site infection(n=1). Our initial experience suggests that ultrasonography is useful for diagnosis of complications and monitoring of patient during long term peritoneal dialysis

Full Text Available Background: Despite a high prevalence of endometriosis, there still exist many challenges indiagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methodsby measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondaryaim is to determine the correlation between these markers with the stage of disease as well as therelationship of the two markers with each other.Materials and Methods: This is a cross-sectional study of 60 women who underwent laparoscopyfor benign conditions. Based on laparoscopic findings and biopsy results, patients were divided to twogroups; one group included patients with pelvic endometriosis (35 patients and the second enrolledpatients free from endometriosis (25 patients. Serum and peritoneal fluid specimens were provided at thetime of laparoscopy and CA125 levels were then assessed by electrochemiluminescence immunoassay.Results: Mean serum and peritoneal fluid CA125 levels were significantly higher in women withendometriosis as compared to the control group (26.42 ± 24.34 IU/ml versus 12.64 ± 6.87 IU/mlin serum and 2203.54 + 993.19 IU/ml versus 1583.42 ± 912.51 IU/ml in peritoneal fluid, p<0.05.CA 125 levels also varied proportionally with the stage of endometriosis; but showed a significantdifference only in higher stages of the disease, both in serum and peritoneal fluid. We calculatedthe cut-off value suggesting a diagnosis of pelvic endometriosis as 14.70 IU/ml for serum and1286.5 IU/ml for peritoneal fluid CA125. A linear correlation between CA 125 levels in serum andperitoneal fluid in patients with pelvic endometriosis has also been observed.Conclusion: Serum and peritoneal fluid CA 125 levels are simple and non-surgical tools fordiagnosing and staging pelvic endometriosis. These markers are of greater diagnostic value inhigher stages of the disease.

Peritoneal dialysis (PD) for the treatment of end-stage renal failure was introduced in the 1960s. Nowadays it has evolved to an established therapy that is complementary to hemodialysis (HD), representing 11% of all patients treated worldwide with dialysis. Despite good clinical outcomes and similar results in patient survival between PD and HD, the penetration of PD is decreasing in the Western world. First the major events in the history of the development of PD are described. Then important insights into the physiology of peritoneal transport are discussed and linked to the changes in time observed in biopsies of the peritoneal membrane. Furthermore, the developments in peritoneal access, more biocompatible dialysate solutions, automated PD at home, the establishment of parameters for dialysis adequacy and strategies to prevent infectious complications are mentioned. Finally non-medical issues responsible for the declining penetration in the Western world are analyzed. Only after introduction of the concept of continuous ambulatory PD by Moncrief and Popovich has this treatment evolved in time to a renal replacement therapy. Of all structures present in the peritoneal membrane, the capillary endothelium offers the rate-limiting hindrance for solute and water transport for the diffusive and convective transport of solutes and osmosis. The functional and anatomical changes in the peritoneal membrane in time can be monitored by the peritoneal equilibrium test. Peritonitis incidence decreased by introduction of the Y-set and prophylaxis using mupirocin on the exit site. The decrease in the proportion of patients treated with PD in the Western world can be explained by non-medical issues such as inadequate predialysis patient education, physician experience and training, ease of HD initiation, overcapacity of in-center HD, lack of adequate infrastructure for PD treatment, costs and reimbursement issues of the treatment. (1) PD is cheaper than HD and provides a

To investigate the effect of gonadotropin-releasing hormone analogues (GnRHa) on the peritoneal fluid microenvironment in women with endometriosis. Peritoneal fluid was collected from 85 women with severe endometriosis (rAFS stage III and IV) during laparoscopic surgery during the proliferative phase. Prior to surgery clinical data were collected. The concentrations of specific markers for endometriosis in the peritoneal fluid were determined using an ELISA and a comparison between peritoneal fluid markers in women using GnRHa and no hormonal treatment was performed using a non-parametric Mann-Whitney U test. The study included peritoneal fluid from 39 patients who had been administered GnRHa (Zoladex(®)) in the three months prior to surgery and 46 from women with no hormonal treatment in this period. Concentrations of IL-8, PAPP-A, glycodelin-A and midkine were significantly reduced in the GnRHa treatment group compared to women receiving no hormonal treatment. RANTES, MCP-1, ENA-78, TNF-α, OPG, IP-10 and defensin showed no significant change between the two groups. GnRHa mediate a significant regression in the inflammatory nature of the peritoneal microenvironment in women with endometriosis. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To evaluate the technical aspects, results and complications of the percutaneous radiologic placement of peritoneal dialysis catheters. Between December 1999 and April 2001, 26 peritoneal dialysis catheters were placed percutaneously in 26 consecutive patients by interventional radiologists. The patient group consisted of 16 men and ten women with a mean age of 55 (range, 30-77) years. The results and complications arising were reviewed, and the expected patency of the catheters was determined by means of Kaplan-Meier survival analysis. The technical success rate for catheter placement was 100% (26/26 patients). Severe local bleeding occurred in one patient due to by inferior epigastric artery puncture, and was treated by compression and electronic cautery. The duration of catheter implantation ranged from 1 to 510 days and the patency rate was 416±45 days. Catheter malfunction occurred in four patients. In two, this was restored by manipulation in the intervention room, and in one, through the use of urokinase. In three patients, peritonitis occurred. Catheters were removed from four patients due to malfunction (n=2), peritonitis (n=1), and death (n=1). Percutaneous radiologic placement of a peritoneal dialysis catheter is a relatively simple procedure that reduces the complication rate and improves catheter patency

Internal radiotherapy involving systemic administration of iodine-131 metaiodobenzylguanidine ( 131 I-MIBG) in neural crest tumours such as neuroblastoma has shown considerable success. Although peritoneal seeding of neuroblastoma occurs less often than metastases to organs such as the liver, no effective treatments exist in this clinical setting. Previous reports have demonstrated the effectiveness of peritoneal application of chemotherapeutic drugs or radiolabelled monoclonal antibodies in several kinds of carcinomas. Local delivery of 131 I-MIBG should produce more favourable dosimetry in comparison with its systemic administration in the treatment of peritoneal neuroblastoma. In the current investigation, a peritoneal model of neuroblastoma was established in Balb/c nu/nu mice by i.p. injection of SK-N-SH neuroblastoma cells. Two weeks after cell inoculation, comparative biodistribution studies were performed following i.v. or i.p. administration of 131 I-MIBG. Mice were treated with 55.5 MBq of 131 I-MIBG administered either i.v. or i.p. at 2 weeks. Intraperitoneal injection of 131 I-MIBG produced significantly higher tumour accumulation than did i.v. injection (P 131 I-MIBG failed to improve the survival of mice; mean survival of untreated mice and mice treated with i.v. administration of 131 I-MIBG was 59.3±3.9 days and 60.6±2.8 days, respectively. On the other hand, radiotherapy delivered via i.p. administration of 131 I-MIBG prolonged survival of mice to 94.7±17.5 days (P 131 I-MIBG therapy). Radiation doses absorbed by tumours at 55.5 MBq of 131 I-MIBG were estimated to be 4,140 cGy with i.p. injection and 450 cGy with i.v. injection. These results indicate the benefits of locoregional delivery of 131 I-MIBG in the treatment of peritoneal neuroblastoma. (orig.)

Mitochondrial damage-associated molecular patterns (mtDAMPs), such as mitochondrial DNA and N-formylated peptides, are endogenous molecules released from tissue after traumatic injury. mtDAMPs are potent activators of the innate immune system. They have similarities with bacteria, which allow mtDAMPs to interact with the same pattern recognition receptors and mediate the development of systemic inflammatory response syndrome (SIRS). Current recommendations for management of an open abdomen include returning to the operating room every 48 hours for peritoneal cavity lavage until definitive procedure. These patients are often critically ill and develop SIRS. We hypothesized that mitochondrial DAMPs are present in the peritoneal cavity fluid in this setting, and that they accumulate in the interval between washouts. We conducted a prospective pilot study of critically ill adult patients undergoing open abdomen management in the surgical and trauma intensive care units. Peritoneal fluid was collected daily from 10 open abdomen patients. Specimens were analyzed via quantitative polymerase chain reaction (qPCR) for mitochondrial DNA (mtDNA), via enzyme immunoassay for DNAse activity and via Western blot analysis for the ND6 subunit of the NADH: ubiquinone oxidoreductase, an N-formylated peptide. We observed a reduction in the expression of ND6 the day after lavage of the peritoneal cavity, that was statistically different from the days with no lavage (% change in ND6 expression, postoperative from washout: -50 ± 11 vs. no washout day, 42 ± 9; p abdomen. It is possible that increased frequency of peritoneal cavity lavage may lead to decreased systemic absorption of mtDAMPs, thereby reducing the risk of SIRS. Prospective study, Case Series, Level V.

To describe peritoneal manifestations of fascioliasis on CT. We reviewed CT images in 31 patients with fascioliasis confirmed by enzyme-linked immunosorbent assay (ELISA) (n = 24) or surgery (n = 7). Image analyses were performed to identify hepatic, biliary, and peritoneal abnormalities. Hepatic abnormalities were seen in 28 (90.3 %) of the 31 patients. The most common finding was caves sign, which was present in 25 (80.1 %) patients. Three patients (9.7 %) presented with biliary abnormalities exhibiting dilatation and enhancing wall thickening of the bile duct, wall thickening of the gallbladder, and elongated structures in the bile duct or gallbladder. Peritoneal abnormalities were seen in 14 (45.2 %) of the 31 patients. The most common peritoneal abnormality was mesenteric or omental infiltration, which was seen in 9 (29.0 %) patients. Other peritoneal findings included lymph node enlargement (n = 7), ascites (n = 7), thickening of ligamentum teres (n = 2), and peritoneal mass (n = 2). Peritoneal manifestations of fascioliasis are relatively common, and CT findings include mesenteric or omental infiltration, lymph node enlargement, ascites, thickening of the ligamentum teres, and peritoneal masses.

♦ Previous studies have reported significant variation in peritonitis rates across dialysis centers. Limited evidence is available to explain this variability. The aim of this study was to assess center-level predictors of peritonitis and their relationship with peritonitis rate variations. ♦ All incident peritoneal dialysis (PD) patients treated in Australia between October 2003 and December 2013 were included. Data were accessed through the Australia and New Zealand Dialysis and Transplant Registry. The primary outcome was peritonitis rate, evaluated in a mixed effects negative binomial regression model. Peritonitis-free survival was assessed as a secondary outcome in a Cox proportional hazards model. ♦ Overall, 8,711 incident PD patients from 51 dialysis centers were included in the study. Center-level predictors of lower peritonitis rates included smaller center size, high proportion of PD, low peritoneal equilibration test use at PD start, and low proportion of hospitalization for peritonitis. In contrast, a low proportion of automated PD exposure, high icodextrin exposure and low or high use of antifungal prophylaxis at the time of peritonitis were associated with a higher peritonitis rate. Similar results were obtained for peritonitis-free survival. Overall, accounting for center-level characteristics appreciably decreased peritonitis variability among dialysis centers (p = 0.02). ♦ This study identified specific center-level characteristics associated with the variation in peritonitis risk. Whether these factors are directly related to peritonitis risk or surrogate markers for other center characteristics is uncertain and should be validated in further studies.

Interleukin 33 (IL-33) is a cytokine involved in fibrotic disorders. We have analyzed IL-33 levels in the sera and peritoneal fluids of women with various forms of endometriosis and investigated the correlation with disease activity. We conducted a prospective laboratory study in a tertiary-care university hospital between January 2005 and December 2010. Five hundred and ten women with histologically proven endometriosis and 132 endometriosis-free controls were enrolled in this study. Complete surgical exploration of the abdominopelvic cavity was performed in each patient. Blood samples and peritoneal fluids were obtained before and during surgical procedures, respectively. IL-33 was measured by an enzyme-linked immunosorbent assay in sera and peritoneal fluids, and the concentrations correlated with the extent and the severity of endometriotic lesions. IL-33 was detectable in 23.1% of serum samples from all 642 women studied and 75.0% of peritoneal fluid samples studied (44 women with endometriosis and 36 controls). Serum IL-33 was higher in deeply infiltrating endometriosis (DIE) (median, 104.9 pg/ml; range, 8.0-104.9) than in endometriosis-free women (median, 61.3 pg/ml; range, 7.5-526.0; P = 0.022) or in women affected by superficial endometriosis (median, 36.8 pg/ml; range, 7.5-179.0; P Peritoneal IL-33 was higher in DIE than in endometriosis-free women (median, 642.0 pg/ml; range, 25.9-3350.6 versus median, 194.2 pg/ml; range, 12.7-1818.2, respectively; P = 0.003). We found positive correlations between serum IL-33 concentration and intensity of dysmenorrhea (r = 0.174; P = 0.028) and gastrointestinal symptoms (r = 0.199; P = 0.027), total number of DIE lesions (r = 0.224; P = 0.016) and the worst DIE lesion (r = 0.299; P endometriosis and principally in DIE. Elevated serum IL-33 is correlated with the intensity of preoperative painful symptoms, and with the extent and severity of the DIE. IL-33 may be considered as a novel cytokine involved in the

BACKGROUND: Predicting the clinical course in adhesional small bowel obstruction is difficult. There are no validated clinical or radiologic features that allow early identification of patients likely to require surgical intervention. METHODS: We conducted a retrospective review of 100 patients consecutively admitted to a tertiary level teaching hospital over a 3-year period (2002-2004) who had acute adhesional small bowel obstruction and underwent computed tomography (CT). The primary outcomes that we assessed were conservative management or the need for surgical intervention. We investigated time to physiologic gastrointestinal function recovery as a secondary outcome. We examined independent predictors of surgical intervention in a bivariate analysis using a stepwise logistic regression analysis. RESULTS: Of the 100 patients investigated, we excluded 12. Of the 88 remaining patients, 58 (66%) were managed conservatively and 30 (34%) underwent surgery. Peritoneal fluid detected on a CT scan (n = 37) was associated more frequently with surgery than conservative management (46% v. 29%, p = 0.046, chi(2)). Logistical regression identified peritoneal fluid detected on a CT scan as an independent predictor of surgical intervention (odds ratio 3.0, 95% confidence interval 1.15-7.84). CONCLUSION: The presence of peritoneal fluid on a CT scan in patients with adhesional small bowel obstruction is an independent predictor of surgical intervention and should alert the clinician that the patient is 3 times more likely to require surgery.

To investigate impact of prophylactic peritoneal dialysis (PD) on clinical outcomes and inflammatory cytokines in children following cardiac surgery with cardiopulmonary bypass. Prospective before-and-after nonrandomized cohort study. Pediatric cardiovascular intensive care unit in tertiary hospital. Fifty-two consecutive neonates and infants at high risk for postoperative fluid overload following cardiopulmonary bypass. All had PD catheters placed during primary cardiac surgery. Initial 27 patients were managed with passive peritoneal drainage and diuretics (controls). Following 25 patients were started on prophylactic PD in immediate postoperative period and managed per PD protocol (+PD). Cumulative fluid balance, indices of disease severity, and clinical outcomes were prospectively collected. Plasma interleukin-6 and interleukin-8 were measured immediately before-and-after cardiopulmonary bypass and at 24 and 48 hours post-cardiopulmonary bypass. Demographics, diagnoses, and intraoperative variables were similar. Median net fluid balance was more negative in +PD at 24 hours, -24 mL/kg (interquartile range: -62, 11) vs. +18 mL/kg (interquartile range: -26, 11), P = .003, and 48 hours, -88 mL/kg (interquartile range: -132, -54) vs. -46 mL/kg (interquartile range: -84, -12), P = .004. +PD had median 55 mL/kg less fluid intake at 24 hours, P = .058. Peritoneal drain, urine, and chest tube output were comparable over first 24 hours. Mean inotrope score was lower in +PD at 24 hours. +PD had earlier sternal closure--24 hours (interquartile range: 20, 40) vs. 63 hours (interquartile range: 44, 72), P interquartile range: 49, 135) vs. 125 hours (interquartile range: 70, 195), P = .10. +PD experienced lower serum concentrations of interleukin-6 and interleukin-8 at 24 hours. Prophylactic PD is associated with greater net negative fluid balance, decreased inotrope requirements, and lower serum concentrations of inflammatory cytokines in the early postoperative

Peritoneal Dialysis Tailored to Pediatric Needs

Full Text Available Consideration of specific pediatric aspects is essential to achieve adequate peritoneal dialysis (PD treatment in children. These are first of all the rapid growth, in particular during infancy and puberty, which must be accompanied by a positive calcium balance, and the age dependent changes in body composition. The high total body water content and the high ultrafiltration rates required in anuric infants for adequate nutrition predispose to overshooting convective sodium losses and severe hypotension. Tissue fragility and rapid increases in intraabdominal fat mass predispose to hernia and dialysate leaks. Peritoneal equilibration tests should repeatedly been performed to optimize individual dwell time. Intraperitoneal pressure measurements give an objective measure of intraperitoneal filling, which allow for an optimized dwell volume, that is, increased dialysis efficiency without increasing the risk of hernias, leaks, and retrofiltration. We present the concept of adapted PD, that is, the combination of short dwells with low fill volume to promote ultrafiltration and long dwells with a high fill volume to improve purification within one PD session. The use of PD solutions with low glucose degradation product content is recommended in children, but unfortunately still not feasible in many countries.

Intraperitoneal pressure in peritoneal dialysis

Directory of Open Access Journals (Sweden)

Vicente Pérez Díaz

Full Text Available The measure of intraperitoneal pressure in peritoneal dialysis is easy and provides clear therapeutic benefits. However it is measured only rarely in adult peritoneal dialysis units. This review aims to disseminate the usefulness of measuring intraperitoneal pressure. This measurement is performed in supine before initiating the drain of a manual exchange with “Y” system, by raising the drain bag and measuring from the mid-axillary line the height of the liquid column that rises from the patient. With typical values of 10–16 cm H2O, intraperitoneal pressure should never exceed 18 cm H2O. With basal values that depend on body mass index, it increases 1–3 cm H2O/L of intraperitoneal volume, and varies with posture and physical activity. Its increase causes discomfort, sleep and breathing disturbances, and has been linked to the occurrence of leaks, hernias, hydrothorax, gastro-esophageal reflux and enteric peritonitis. Less known and valued is its ability to decrease the effectiveness of dialysis significantly counteracting ultrafiltration and decreasing solute clearance to a smaller degree. Because of its easy measurement and potential utility, should be monitored in case of ultrafiltration failure to rule out its eventual contribution in some patients. Although not yet mentioned in the clinical practice guidelines for PD, its clear benefits justify its inclusion among the periodic measurements to consider for prescribing and monitoring peritoneal dialysis. Resumen: La medida de la presión intraperitoneal en diálisis peritoneal es muy sencilla y aporta claros beneficios terapéuticos. Sin embargo, su monitorización todavía no se ha generalizado en las unidades de diálisis peritoneal de adultos. Esta revisión pretende divulgar su conocimiento y la utilidad de su medida.

Laparoscopy for abdominal surgical emergencies is gaining increasing acceptance given the spreading of advanced laparoscopic skills among modern surgeons, as it may allow at the same time an accurate diagnosis and appropriate treatment of acute abdomen. The use of the laparoscopic approach also in case of diffuse peritonitis is now becoming accepted provided hemodynamic stability, despite the common belief in the past decades that such severe condition represented an indication for conversion to open surgery or an immediate contraindication to continue laparoscopy. Crohn's Disease (CD) is a rare cause of acute abdomen and peritonitis, only a few cases of CD acute perforations are reported in the published literature; these cases have always been approached and treated by open laparotomy. We report on a case of a faecal peritonitis due to an acute perforation caused by a terminal ileitis in an undiagnosed CD. The patient underwent diagnostic laparoscopy followed by a laparoscopic ileo-colic resection and primary intracorporeal anastomosis, with a successful postoperative outcome. Complicated CD has to be considered within the possible causes of small bowel non-traumatic perforation. Emergency laparoscopy with resection and primary intra-corporeal anastomosis can be feasible and may be a safe and effective minimally invasive alternative to open surgery even in case of faecal peritonitis, in selected stable patients and in presence of appropriate laparoscopic colorectal surgical skills and experience. To the best of our knowledge the present experience is the first ever reported case managed with a totally laparoscopic extended ileocecal resection with intracorporeal anastomosis in case of acutely perforated CD and diffuse peritonitis.

To evaluate the ultrasonographic findings of the patients with sclerosing encapsulating peritonitis (SEP). Thirteen patients with surgically confirmed sclerosing encapsulating peritonitis were involved in this study. Because of intestinal obstruction, all patients had received operations. Among 13 patients, 12 cases had continuous ambulatory peritoneal dialysis (CAPD) for 2 months-12 years and 4 months from (mean; 6 years and 10 months), owing to chronic renal failure and one patient had an operation due to variceal bleeding caused by liver cirrhosis. On ultrasonographic examination, all patients showed loculated ascites which were large (n=7) or small (n=6) in amount with multiple separations. The small bowel loops were tethered posteriorly perisaltic movement and covered with the thick membrane. The ultrasonographic of findings of sclerosing encapsulating peritonitis were posteriorly tethered small bowels covered with a thick membrane and loculated ascites with multiple septa. Ultrasonographic examination can detect the thin membrane covering the small bowel loops in the early phase of the disease, therefore ultrasonography would be a helpful modality to diagnose SEP early.

When compared to hemodialysis, peritoneal dialysis is very simple yet low cost method of renal replacement therapy. Series of studies have shown its superiority in preserving residual renal function, postponing uremic complications, maintaining the acid-base balance and achieving better post-transplant outcome in patients treated with this method. Despite obvious advantages, its role in the treatment of chronic kidney disease is still not as important as it should be. Metabolic acidosis is an inevitable complication associated with progressive loss of kidney function. Its impact on mineral and muscle metabolism, residual renal function, allograft function and anemia is very complex but can be successfully managed. The aim of our study was to evaluate the efficiency in preserving the acid-base balance in patients undergoing peritoneal dialysis at Zagreb University Hospital Center. Twenty-eight patients were enrolled in the study. The mean time spent on the treatment was 32.39 ± 43.43 months. Only lactate-buffered peritoneal dialysis fluids were used in the treatment. Acid-base balance was completely maintained in 73.07% of patients; 11.54% of patients were found in the state of mild metabolic acidosis, and the same percentage of patients were in the state of mild metabolic alkalosis. In one patient, mixed alkalosis with respiratory and metabolic component was present. The results of this study showed that acid-base balance could be maintained successfully in patients undergoing peritoneal dialysis, even only with lactate-buffered solutions included in the treatment, although they were continuously proclaimed as inferior in comparison with bicarbonate-buffered ones. In well educated and informed patients who carefully use this method, accompanied by the attentive and thorough care of their physicians, this method can provide quality continuous replacement of lost renal function as well as better quality of life.

Vernix caseosa peritonitis is a rare complication caused by inflammatory response to amniotic fluid spilled into the maternal peritoneal cavity. Most cases occur after cesarean section. We discuss herein two patients, aged 33 and 29 years, who presented with vernix caseosa peritonitis seven to nine days after a cesarean delivery. Laparotomy was performed and it revealed neither uterine rupture nor other surgical emergencies, but cheesy exudates on the serosal surface of all viscera. Appendicectomy was performed. Histopathologic study revealed acute fibrinous serositis and a mixed cellular infiltrate, rich in neutrophils, around fetal desquamated anucleate squamous cells. Patients´ recovery was complete. Clinical diagnosis of vernix caseosa peritonitis should be suspected in patients presenting post-cesarean section with an acute abdomen. Distinctive histopathologic findings allow making the correct diagnosis. Vigilant monitoring after diagnosis is essential as delayed morbidities may appear.

Volume overload is frequent in diabetics undergoing peritoneal dialysis (PD), and may play a significant role in the excess mortality observed in these patients. The characteristics of peritoneal water transport in this population have not been studied sufficiently. Following a prospective, single-center design we made cross-sectional and longitudinal comparisons of peritoneal water transport in 2 relatively large samples of diabetic and nondiabetic PD patients. We used 3.86/4.25% glucose-based peritoneal equilibration tests (PET) with complete drainage at 60 min, for these purposes. We scrutinized 59 diabetic and 120 nondiabetic PD patients. Both samples showed relatively similar characteristics, although diabetics were significantly more overhydrated than nondiabetics. The baseline PET disclosed lower ultrafiltration (mean 439 mL diabetics vs. 532 mL nondiabetics, p = 0.033) and sodium removal (41 vs. 53 mM, p = 0.014) rates in diabetics. One hundred and nine patients (36 diabetics) underwent a second PET after 12 months, and 45 (14 diabetics) underwent a third one after 24 months. Longitudinal analyses disclosed an essential stability of water transport in both groups, although nondiabetic patients showed a trend where an increase in free water transport (p = 0.033) was observed, which was not the case in diabetics. Diabetic patients undergoing PD present lower capacities of ultrafiltration and sodium removal than their nondiabetic counterparts. Longitudinal analyses disclose an essential stability of water transport capacities, both in diabetics and nondiabetics. The clinical significance of these differences deserves further analysis. © 2017 S. Karger AG, Basel.

Purpose: To evaluate the ultrasonographic and CT findings of tuberculous peritonitis. Material and Methods: Ultrasonographic and CT findings of 11 patients with the ascitic type of tuberculous peritonitis were reviewed. Results: All patients had ascites, and ultrasonography (US) demonstrated fine complete and incomplete mobile septations in 10 patients. In 5 of them, the ascites had a lattice-like appearance. Diffuse regular peritoneal thickening was detected in all patients by CT and in 10 patients by US. CT demonstrated infiltration of the greater omentum in 9 patients, whereas US showed omental thickening in only 5 patients. Conclusion: Peritoneal and omental thickening detected by CT and ascites with fine, mobile septations shown by US strongly suggest the ascitic type of tuberculous peritonitis. The 2 imaging modalities should be used together for accurate diagnosis of tuberculous peritonitis. (orig.).

Management of Diverticular Disease in Scandinavia.

Schultz, Johannes K; Yaqub, Sheraz; Øresland, Tom

2016-10-01

Throughout the last century, the incidence of diverticular disease of the colon has increased tremendously in industrialized countries; nevertheless, the management of this condition is still controversial. Although several international guidelines for the management of diverticular disease are based on the same evidence, the recommendations differ greatly, emphasizing the lack of high-quality prospective studies. In Scandinavia, official guidelines for the management of diverticular disease exist only in Denmark. However, the treatment policies are quite similar in all Scandinavian countries. Computed tomography is the first choice for imaging of acute diverticulitis and its complications. Furthermore, the use of antibiotics in uncomplicated diverticulitis is nearly abandoned in Scandinavia, whereas several international guidelines still recommend their use. There is a broad consensus that abscesses secondary to acute diverticulitis can safely be managed with percutaneous drainage, which is in line with international recommendations. The surgical management of perforated diverticulitis with peritonitis is still as controversial in Scandinavia as elsewhere. Common surgical options are laparoscopic peritoneal lavage, primary resection with anastomosis, and primary resection with terminal colostomy (Hartmann's procedure). Elective sigmoid resection in patients with diverticular disease seems to be performed less frequently in Scandinavia than in other European countries; the right indications are a current matter of debate. Symptomatic uncomplicated diverticular disease in the absence of diverticulitis has not gained great attention in Scandinavia.

We report here an unusual presentation of peritoneal endometriosis with smooth muscle metaplasia as multiple protruding masses on the lateral pelvic wall. Smooth muscle metaplasia is a common finding in rectovaginal endometriosis, whereas in peritoneal endometriosis, smooth muscle metaplasia is uncommon and its nodular presentation on the pelvic wall is even rarer. To the best of our knowledge, this is the first case of nodular smooth muscle metaplasia occurring in peritoneal endometriosis. A...

Peritoneal surface malignancy (PSM) is a clinical entity with an unfavourable prognosis, which characterizes the evolution of neoplastic diseases from the abdominal and/or pelvic organs and could also be the terminal stage of extra-abdominal tumors. Examples of diseases that can spread mainly within the peritoneal cavity are appendiceal tumors, ovarian cancer, colorectal cancer, abdominal sarcomatosis, gastric cancer and peritoneal mesothelioma. The locoregional therapy is defined as the combination of cytoreductive surgery (CRS) and intraperitoneal hyperthermic perfusion (IPHP). The rationale of this combined therapy for PSM is based on the natural history of this clinical entity that remains confined in the peritoneal cavity for most of its natural history. This pattern of spread would seem to indicate the potential usefulness of selectively increasing drug concentration in the tumour-bearing area by direct intraperitoneal chemotherapy instillation. This approach led to these outcomes: the median survival of colorectal carcinoma and ovarian cancer was 32 months; patients with peritoneal mesothelioma showed 57% survival at 5 years, while in patients with appendiceal mucinous tumors and pseudomyxoma peritonei (PMP) the 10 years overall survival was 78%. A significant improvement in survival was associated with hyperthermic intra-peritoneal chemotherapy (HIPEC) in patients with gastric cancer. Considering the constant increasing of diseases treatable with this procedure, more centres should be activated. The establishment of a clear policy and scientific guidelines is mandatory, in order to perform the CRS+HIPEC safely, minimizing treatment-related morbidity and mortality and maximizing the results in terms of survival and quality of life.

Kirchner, J.; Kirchner, E.M.; Kickuth, R.; Stein, A.

2004-01-01

Sclerosing peritonitis already has been described as a serious complication of the continuous ambulatory peritoneal dialysis. But different other affections of the pertioneum such as chronic bacterial peritonitis and pancreatitis may result in sclerosing peritonitis, too. The symptom is characterised by thickened small bowel walls and periotoneal membranes as well as peritoneal calcifications which can be shown in computed tomography. We demonstrate two cases of peritoneal ossifications due to peritonitis and pancreatitis. (orig.) [de

Comparative Proteomic Analysis of Peritoneal Dialysate from Chronic Glomerulonephritis Patients

Directory of Open Access Journals (Sweden)

2013-01-01

Full Text Available Peritoneal dialysis (PD frequently contributes to peritoneal damage which cannot be easily identified without invasive techniques, implying the urgent need for biomarkers and revealing mechanisms. Chronic glomerulonephritis (CGN is one of the leading causes of receiving dialysis treatment. Here, we attempted to analyze the peritoneal dialysate collected from CGN patients when they receive continuous ambulatory peritoneal dialysis (CAPD treatment for the first time and after a year to reveal the protein changes that resulted from PD. Proteins were displayed by two-dimensional gel electrophoresis (2DE. Altered gel spots were digested followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS analysis for protein identification. Eight proteins were found to have differential expression levels between two groups. Their differential expressions were validated by Western blots in other sets of peritoneal dialysates. Proteins identified with higher levels in the first-time dialysate suggested their dominant appearance in CGN patients, while those that showed higher levels in peritoneal dialysate collected after one year may result from initial peritoneal inflammation or changes in the permeability of the peritoneum to middle-sized proteins. All the identified proteins may provide a perceptiveness of peritoneal changes caused by PD and may function as potential biomarkers or drug targets.

Fifty patients with peritonitis carcinomatosa were evaluated with computed tomography (CT). CT findings included evidence of mesenteric thickening (60 %), solid mass (20 %), loculated ascites (16 %), ascites (14 %), partly dilated intestine (10 %). Mesenteric thickening showed both intraperitoneal and subperitoneal metastasis. Arrested flow of ascitic fluid (loculated ascites) was one of the most predicting findings of peritonitis carcinomatosa. The seven false negative cases related to small metastatic foci, long distance between autopsy and the last CT examination, or paucity of intraabdominal fat. (author)

To investigate possible mechanisms of pain pathophysiology in patients with peritoneal endometriosis, a clinical study on sensory and sympathetic nerve fibre sprouting in endometriosis was performed. Peritoneal lesions (n=40) and healthy peritoneum (n=12) were immunostained and analysed with anti-protein gene product 9.5 (PGP 9.5), anti-substance P (SP) and anti-tyrosine hydroxylase (TH), specific markers for intact nerve fibres, sensory nerve fibres and sympathetic nerve fibres, respectively, to identify the ratio of sympathetic and sensory nerve fibres. In addition, immune cell infiltrates in peritoneal endometriotic lesions were analysed and the nerve growth factor (NGF) and interleukin (IL)-1β expression was correlate with the nerve fibre density. Peritoneal fluids from patients with endometriosis (n=40) and without endometriosis (n=20) were used for the in vitro neuronal growth assay. Cultured chicken dorsal root ganglia (DRG) and sympathetic ganglia were stained with anti-growth associated protein 43 (anti-GAP 43), anti-SP and anti-TH. We could detect an increased sensory and decreased sympathetic nerve fibres density in peritoneal lesions compared to healthy peritoneum. Peritoneal fluids of patients with endometriosis compared to patients without endometriosis induced an increased sprouting of sensory neurites from DRG and decreased neurite outgrowth from sympathetic ganglia. In conclusion, this study demonstrates an imbalance between sympathetic and sensory nerve fibres in peritoneal endometriosis, as well as an altered modulation of peritoneal fluids from patients with endometriosis on sympathetic and sensory innervation which might directly be involved in the maintenance of inflammation and pain.

2013-01-01

Vernix caseosa peritonitis (VCP) is a very unusual complication caused by inflammatory response to amniotic fluid spilled into the maternal peritoneal cavity. Twenty-seven cases have been reported, and all occurred after cesarean section. We present a case of VCP following vaginal delivery; this may be the first case reported after vaginal delivery. Mrs. A, 28 years old, gravida 3, para 2, with one previous cesarean section, was admitted at 41 weeks gestation in active labor. Vacuum extraction was performed to deliver a healthy male baby, 4.410 kg, Apgar scores 7, 8. She developed fever, acute abdominal pain, and distension about 3 hours after delivery. A diagnosis of acute abdomen was made. Laparotomy was performed and it revealed neither uterine scar rupture nor other surgical emergencies, but 500 mL of turbid fluid and some cheesy material on the serosal surface of all viscera. Biopsies were taken. She had a course of antibiotics and her recovery was complete. Histology of the peritoneal fluid and tissue biopsy resulted in a diagnosis of VCP. Clinical diagnosis of peritonitis due to vernix caseosa should be considered in patients presenting postpartum with an acute abdomen after vaginal delivery.

2014-01-01

Full Text Available Background: Many reconstructive surgical procedures have been described for vaginal agenesis. Almost all of them are surgically challenging, multi-staged, time consuming or leave permanent scars on abdomen or skin retrieval sites. Aim: A new simple technique using laparoscopic peritoneal pull-through in creation of neo vagina has been described. Material and Methods: Total of thirty six patients with congenital absence of vagina (MRKH syndrome were treated with laparoscopic peritoneal pull through technique of Dr. Mhatre between 2003 till 2012. The author has described 3 different techniques of peritoneal vaginoplasty. Results: This technique has given excellent results over a period of one to seven years of follow-up. The peritoneal lining changes to stratified squamous epithelium resembling normal vagina and having acidic Ph. Conclusion: Apart from giving excellent normal vaginal function, as the ovary became accessible per vaginum three patients underwent ovum retrieval and pregnancy using surrogate mother, thus making this a fertility enhancing procedure.

Background. Patients with peritoneal dialysis-related peritonitis usually have different responses to initial antibiotic treatment. This study aimed to explore the patterns of response by using the changes of dialysate white blood cell count on the first five days of the initial antibiotic treatment. Materials and Methods. A retrospective cohort study was conducted. All peritoneal dialysis-related peritonitis episodes from January 2014 to December 2015 were reviewed. We categorized the patterns of antibiotic response into 3 groups: early response, delayed response, and failure group. The changes of dialysate white blood cell count for each pattern were determined by multilevel regression analysis. Results. There were 644 episodes in 455 patients: 378 (58.7%) of early response, 122 (18.9%) of delayed response, and 144 (22.3%) of failure episodes. The patterns of early, delayed, and failure groups were represented by the average rate reduction per day of dialysate WBC of 68.4%, 34.0%, and 14.2%, respectively (p value patterns, which were categorized by types of responses, have variable rates of WBC declining. Clinicians should focus on the delayed response and failure patterns in order to make a decision whether to continue medical therapies or to aggressively remove the peritoneal catheter.

2008-07-01

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent. Copyright © 2015 European Society of Clinical Microbiology and Infectious Diseases. Published by Elsevier Ltd.

To describe a technique for abdominocentesis in camelids and report peritoneal fluid biochemical and cytologic findings from healthy llamas and alpacas. Prospective study. Animals-17 adult llamas and 5 adult alpacas. Right paracostal abdominocentesis was performed. Peritoneal fluid was collected by gravity flow into tubes containing potassium-EDTA for cell count and cytologic evaluation and lithium heparin for biochemical analysis. Blood samples were collected via jugular venipuncture into heparinized tubes at the same time. Cytologic components were quantified. Fluid pH and concentrations of total carbon dioxide, sodium, potassium, chloride, lactate, and glucose were compared between peritoneal fluid and venous blood. All but 3 camelids had peritoneal fluid cell counts of or = 2.5 g/dL. Peritoneal fluid of camelids generally contained slightly less glucose, lactate, and sodium and roughly equal concentrations of potassium and chloride as venous blood. Peritoneal fluid was collected safely from healthy camelids. Compared with blood, peritoneal fluid usually had a low cell count and protein concentration, but some individuals had higher values. Electrolyte concentrations resembled those found in blood. High cell counts and protein concentrations found in peritoneal fluid of some healthy camelids may overlap with values found in diseased camelids, complicating interpretation of peritoneal fluid values.

1988-01-01

We provided partial peritoneal alimentation to a 1.69-kg 11-month-old premature infant who had no available central venous access, depleted peripheral venous access, and gastrointestinal dysfunction. A cuffed silastic catheter was surgically inserted into the suprahepatic space. An alimentation solution was continuously infused into the peritoneum for 28 days to supplement peripheral venous and nasogastric alimentation and contributed 42 +/- 15% of total calories daily. Weight gain was achieved, but complications included hypoglycemia, hypophosphatemia, intravascular dehydration, catheter site leakage, ascites, and hydrocele. At autopsy 11 months later, lipid accumulation was present in the upper peritoneum and the hilar regions of the lungs secondary to preexisting lymphatic obstruction. Partial peritoneal alimentation may be feasible when other access routes are inadequate, but lymphatic obstruction is a contraindication to the peritoneal administration of lipid emulsions.

To describe a severe case of bacterial sepsis and disseminated candidiasis in a previously healthy dog. Fungal sepsis was identified in a 2-year-old dog following intestinal dehiscence 4 days after abdominal surgery. Septic peritonitis was identified at admission and evidence of dehiscence at the previous enterotomy site was found during an exploratory laparotomy. Both gram-positive cocci and Candida albicans were cultured from the abdominal cavity. Candida sp. was also subsequently cultured from a central venous catheter. Euthanasia was performed due to failure to respond to therapy. Fungal organisms, morphologically consistent with Candida spp., were found in the lungs and kidney on postmortem histopathologic examination indicating disseminated candidiasis. Candida peritonitis is a well-recognized entity in humans and contributes to morbidity and mortality in critically ill patients. Abdominal surgery, intestinal perforation, presence of central venous catheters, and administration of broad-spectrum antibiotics are all considered to be suspected risk factors. This report describes the first known case of systemic candidiasis occurring secondary to Candida peritonitis and bacterial sepsis in a critically ill dog.

Sampson's theory cannot explain why only some cycling women develop peritoneal endometriosis. Few studies have focused on the pelvic peritoneum, which receives regurgitated endometrial tissues. We hypothesized that molecular alterations in the peritoneum are involved in the development of peritoneal endometriosis and conducted a microarray analysis to compare macroscopically normal peritoneum sampled from women with peritoneal endometriosis (endometriotic peritoneum) and those without (non-endometriotic peritoneum). Versican, a major proteoglycan component of the extracellular matrix, is one of the molecules up-regulated in endometriotic peritoneum. To investigate the role of versican in peritoneal endometriosis. Design, Patients, and Main Outcome Measure: Endometriotic peritoneum and non-endometriotic peritoneum were subjected to RT-PCR, immunostaining, and Western blotting. The versican V1 isoform was stably transfected into Chinese hamster ovary cells (CHO-V1), and the effects of CHO-V1-derived conditioned medium (V1-CM) on primary human endometrial stromal cells were investigated with attachment, invasion, and proliferation assays. The effects of peritoneal fluid collected from endometriotic women (endometriotic PF) or cytokines/growth factors, which were shown to be elevated in endometriotic PF, on versican expression in a human peritoneal cell line (HMrSV5) were also examined. Versican V1 expression levels were significantly higher in endometriotic peritoneum. In vitro, V1-CM promoted attachment to the HMrSV5 cell monolayer as well as the Matrigel invasion of endometrial stromal cells. Although versican V1 expression was up-regulated by TGF-β1 in HMrSV5 cells, it remained unchanged in endometriotic PF. Our results suggest the involvement of peritoneal versican in the development of peritoneal endometriosis.

Peritoneal lymphomatosis is uncommon, but when encountered is associated with aggressive histological subtypes of high-grade lymphoma, such as small-cell, large-cell, mixed large and small cell, non-cleaved, lymphoblastic Burkitt-like, and diffuse large B-cell lymphomas. The CT findings of peritoneal lymphomatosis are linear or nodular peritoneal thickening, retroperitoneal lymphadenopathy, omental and mesenteric involvement with streak-like infiltrations or a bulky mass, bowel wall thickening, hepatosplenomegaly, and ascites. The authors reports report the first FDG PET/CT images of diffuse large B-cell lymphoma of small bowel origin associated with peritoneal lymphomatosis in a 69-year-old man. The lesions demonstrated intense FDG uptake in PET/CT images.

Flow cytometric quantification of radiation responses of murine peritoneal cells

International Nuclear Information System (INIS)

Tokita, N.; Raju, M.R.

1982-01-01

Methods have been developed to distinguish subpopulations of murine peritoneal cells, and these were applied to the measurement of early changes in peritoneal cells after irradiation. The ratio of the two major subpopulations in the peritoneal fluid, lymphocytes and macrophages, was measured rapidly by means of cell volume distribution analysis as well as by hypotonic propidium iodide (PI) staining. After irradiation, dose and time dependent changes were noted in the cell volume distributions: a rapid loss of peritoneal lymphocytes, and an increase in the mean cell volume of macrophages. The hypotonic PI staining characteristics of the peritoneal cells showed two or three distinctive G 1 peaks. The ratio of the areas of these peaks was also found to be dependent of the radiation dose and the time after irradiation. These results demonstrate that these two parameters may be used to monitor changes induced by irradiation (biological dosimetry), and to sort different peritoneal subpopulations

During peritoneal dialysis, solutes and fluids are exchanged between the capillary blood and the intraperitoneal fluid through a biologic membrane, the peritoneum. Inadequate renal function leads to disturbance in the removal of the extra fluid and waste products. It removes the waste product and extra fluid from the body in renal failure in small animal practice. Peritoneal dialysis is more accessible, more affordable and easier to administer to the small animal patient. The most common indication for peritoneal dialysis in dogs is acute renal failure (ARF. Peritoneal dialysis is an important therapeutic tool for mitigating clinical signs of uremia and giving the kidneys time to recover in cats with acute kidney injury when conventional therapy is no longer effective.

A 45-year-old man experienced dyspnea on effort and was hospitalized due to severe mitral valve regurgitation and atrial fibrillation. He also had alcoholic cirrhosis. After he was stabilized, mitral valve plasty and Maze procedure were performed. The postoperative clinical course was satisfactory. During the follow-up period, he began to suffer from persistent left pleural effusion, which amounted to about 2,500 to 3,000 ml, and required intercostal tube drainage weekly. Therefore a pleuro-peritoneal shunt was implanted. The pleural effusion decreased, and he obtained significant relief from dyspnea. After one year, we confirmed that pleural effusion had not reoccurred, and removed the pleuro-peritoneal shunt.

Full Text Available The dysfunction of the catheter in peritoneal dialysis (PD is a frequent compli-cation. However, perforation of organs are rare, particularly that of the urinary bladder. This re-quires an early diagnosis and prompt treatment of patients. We report here the case of a 38-year-old woman having end-stage renal disease due to autosomal-dominant polycystic kidney disease treated by PD since November 2000. Three years later, she was treated for Staphylococcal peritonitis. Four months later, she presented with a severe urge to urinate at the time of the fluid exchanges. The biochemical analysis of the fluid from the bladder showed that it was dialysis fluid. Injection of contrast through the catheter demonstrated the presence of a fistula between the bladder and the peritoneal cavity. She underwent cystoscopic closure of the fistulous tract and the PD catheter was removed. Subsequently, the patient was treated by hemodialysis. One month later, a second catheter was implanted surgically after confirming the closure of the fistula. Ten days later, she presented with pain at the catheter site and along the tunnel, which was found to be swollen along its track. The injection of contrast produced swelling of the subcutaneous tunnel but without extravasation of the dye. PD was withdrawn and the patient was put back on hemodialysis. Bladder fistula is a rare complication in PD and diagnosis should be suspected when patient complains of an urge to pass urine during the exchanges, which can be confirmed by contrast study showing presence of dye in the bladder. PD may be possible after the closure of the fistula, but recurrence may occur.

Peptic ulcer perforations are a common emergency, but available literature is silent on the exact definition, incidence, management, and complications of peritonitis due to omental patch leakage. Retrospective data were collected on 422 patients who underwent omental patch repair of perforated peptic ulcer between March 20, 1999 and March 20, 2006. The definitive diagnosis of perforated peptic ulcer and omental patch leakage was obtained at surgery. Seventeen (4%) patients experienced generalized peritonitis due to omental patch leakage. Mean age was 60.6 years. Mortality rate was 29.4%, and the mean hospital stay was 23.6 days. Delay in surgical approach, shock on admission, and age were all significantly associated with increased mortality. Peritonitis due to omental patch leakage can result in significant morbidity and mortality. The most common causes of omental patch leakage and operative procedures were unknown and reinsertion of omentum, respectively. Factors such as shock on admission or delayed surgery, have significantly contributed to fatal outcomes and need careful attention.

Pathological lesions of the rectum are common and their management requires detailed knowledge of pelvic anatomy. There has been considerable debate as to the definition of the rectum and the variability of the level of the peritoneal reflection. The lack of a clear consensus was proven in the research by McCullen et al. regarding the current pattern of practice for the investigation of primary rectal cancer by general surgeons. To carry out bibliographic research on the definition of the rectum and level of the peritoneal reflection. A web-based published literature search of PubMed, Ovid Medline, Science Direct and Springer was made. The paper presents the current definitions of proximal and distal margin of the rectum and level of peritoneal reflection based not only on the results of tests on cadavers but also on living humans. The results of tests on living humans allow more accurate qualification of patients for local excision, which is particularly important for patients with colorectal cancer.

Severe Accident Management is a framework to identify and implement the Emergency Response Capabilities that can be used to prevent or mitigate severe accidents and their consequences. The USA NRC has indicated that the development of a licensee plant specific accident management program will be required in order to close out the severe accident regulatory issue (Ref. SECY-88-147). Generic Letter 88-20 ties the Accident management Program to IPE for each plant. The SECY-89-012 defines those actions taken during the course of an accident by the plant operating and technical staff to: 1) prevent core damage, 2) terminate the progress of core damage if it begins and retain the core within the reactor vessel, 3) maintain containment integrity as long as possible, and 4) minimize offsite releases. The subject of this paper is to document the severe accident management activities, which resulted in a plant specific Severe Accident Management Guidelines implementation. They have been developed based on the Krsko IPE (Individual Plant Examination) insights, Generic WOG SAMGs (Westinghouse Owners Group Severe Accident Management Guidances) and plant specific documents developed within this effort. Among the required plant specific actions the following are the most important ones: Identification and documentation of those Krsko plant specific severe accident management features (which also resulted from the IPE investigations). The development of the Krsko plant specific background documents (Severe Accident Plant Specific Strategies and SAMG Setpoint Calculation). Also, paper discusses effort done in the areas of NPP Krsko SAMG review (internal and external ), validation on Krsko Full Scope Simulator (Severe Accident sequences are simulated by MAAP4 in real time) and world 1st IAEA Review of Accident Management Programmes (RAMP).

Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy
