- Abstract
Background: There are limited data on the associations of circulating angiogenic factors with chronic kidney disease (CKD). We investigate the associations of circulating vascular endothelial growth factor (VEGF)-A, angiopoietin-1, angiopoietin-1/VEGF-A ratio, VEGF receptor 1 (VEGFR-1), VEGFR-2, and pentraxin-3 with CKD., Methods: We recruited 201 patients with CKD and 201 community controls without CKD from the greater New Orleans area. CKD was defined as estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m
2 or presence of albuminuria. Multivariable quantile and logistic regression models were used to examine the relationship between angiogenesis-related factors and CKD adjusting for confounding factors., Results: After adjusting for covariables including traditional cardiovascular disease (CVD) risk factors, C-reactive protein, and history of CVD, the medians (interquartile range) were 133.08 (90.39, 204.15) in patients with CKD vs. 114.17 (72.45, 170.32) pg/mL in controls without CKD (p = 0.002 for group difference) for VEGF-A; 3951.2 (2471.9, 6656.6) vs. 4270.5 (2763.7, 6537.2) pg/mL (p = 0.70) for angiopoietin-1; 25.87 (18.09, 47.90) vs. 36.55 (25.71, 61.10) (p = 0.0001) for angiopoietin-1/VEGF-A ratio; 147.81 (122.94, 168.79) vs. 144.16 (123.74, 168.05) ng/mL (p = 0.25) for VEGFR-1; 26.20 (22.67, 29.92) vs. 26.28 (23.10, 29.69) ng/mL (p = 0.31) for VEGFR-2; and 1.01 (0.79, 1.49)vs. 0.89 (0.58, 1.18) ng/mL (p = 0.01) for pentraxin-3, respectively. In addition, an elevated VEGF-A level and decreased angiopoietin-1/VEGF-A ratio were associated with increased odds of CKD., Conclusions: These data indicate that plasma VEGF-A and pentraxin-3 levels were increased and the angiopoietin-1/VEGF-A ratio was decreased in patients with CKD. Future prospective studies are warranted to examine whether angiogenic factors play a role in progression of CKD.- Published

- Abstract
The interrelationship of multiple endothelial biomarkers and chronic kidney disease (CKD) has not been well studied. We measured asymmetric dimethylarginine (ADMA), L-arginine, soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule-1 (sVCAM-1), soluble E-selectin (sE-selectin), von Willebrand factor (vWF), flow-mediated dilation (FMD), and nitroglycerin-induced dilation (NID) in 201 patients with CKD and 201 community-based controls without CKD. Multivariable analyses were used to examine the interrelationship of endothelial biomarkers with CKD. The multivariable-adjusted medians (interquartile ranges) were 0.54 (0.40, 0.75) in patients with CKD vs. 0.25 (0.22, 0.27) μmol /L in controls without CKD (p<0.0001 for group difference) for ADMA; 67.0 (49.6, 86.7) vs. 31.0 (27.7, 34.2) μmol/L (p<0.0001) for L-arginine; 230.0 (171.6, 278.6) vs. 223.9 (178.0, 270.6) ng/mL (p=0.55) for sICAM-1; 981.7 (782.6, 1216.8) vs. 633.2 (507.8, 764.3) ng/mL (p<0.0001) for sVCAM-1; 47.9 (35.0, 62.5) vs. 37.0 (28.9, 48.0) ng/mL (p=0.01) for sE-selectin; 1320 (1044, 1664) vs. 1083 (756, 1359) mU/mL (p=0.008) for vWF; 5.74 (3.29, 8.72) vs. 8.80 (6.50, 11.39)% (p=0.01) for FMD; and 15.2 (13.5, 16.9) vs. 19.1 (17.2, 21.0)% (p=0.0002) for NID, respectively. In addition, the severity of CKD was positively associated with ADMA, L-arginine, sVCAM-1, sE-selectin, and vWF and inversely associated with FMD and NID. Furthermore, FMD and NID were significantly and inversely correlated with ADMA, L-arginine, sVCAM-1, sE-selectin, and vWF. In conclusion, these data indicate that multiple dysfunctions of the endothelium were present among patients with CKD. Interventional studies are warranted to test the effects of treatment of endothelial dysfunction on CKD.

- Abstract
Background/aims: Plasma fluorescent oxidation products (FLOP) constitute a stable and easily measured biomarker of cumulative oxidative stress. However, their association with chronic kidney disease (CKD) has not been studied., Methods: We examined the association of FLOP and CKD in 201 CKD patients and 201 controls without CKD from the community. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) or the presence of albuminuria., Results: Adjusted median (interquartile range) FLOP levels were significantly higher in patients with CKD than in controls [FLOP1 (lipid oxidation products): 215.2 (181.3-268.7) vs. 156.6 (139.6-177.3) fluorescent intensity units/ml, p < 0.0001; FLOP2 (DNA oxidation products): 534.8 (379.3-842.4) vs. 269.9 (232.4-410.5) fluorescent intensity units/ml, p < 0.0001; FLOP3 (protein and phospholipid oxidation products): 51.4 (44.4-66.0) vs. 45.2 (38.3-51.7) fluorescent intensity units/ml, p = 0.002]. Compared with those with a FLOP level below the 75th percentile, participants with a FLOP level above the 75th percentile had increased odds of CKD after adjustment for covariables (FLOP1: odds ratio 13.1, 95% confidence interval 6.2-27.6; FLOP2: odds ratio 5.7, 95% confidence interval 2.9-11.1; FLOP3: odds ratio 2.4, 95% confidence interval 1.2-4.7). Levels of FLOP1, FLOP2 and FLOP3 were related to eGFR (p < 0.0001 for all) and log-transformed urine albumin (p < 0.005 for all) in multivariable-adjusted linear regression models., Conclusion: These data indicate that an elevated FLOP level is associated with CKD status and severity. Future studies are warranted to elucidate its role in the development and progression of CKD., (Copyright © 2012 S. Karger AG, Basel.)

- Abstract
Background/aims: Angiogenesis may play an important role in the renal repair process after injury. We investigated the association between plasma endostatin, an endothelial-specific antiangiogenic factor, and chronic kidney disease (CKD)., Methods: We compared plasma endostatin levels in 201 CKD patients and 201 controls. CKD was defined as estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) or presence of albuminuria (≥30 mg/24 h)., Results: After adjustment for established CKD risk factors, the median (interquartile range) of plasma endostatin was 276.7 ng/dl (199.3-357.5) in patients with CKD and 119.4 ng/dl (103.7-134.6) in controls without CKD (p < 0.0001 for group difference). log-transformed plasma endostatin was significantly and inversely correlated with eGFR (r = -0.83, p < 0.0001) and positively correlated with log-transformed urine albumin (r = 0.66, p < 0.0001) in the study participants. In addition, one standard deviation increase in log-transformed plasma endostatin (0.55 ng/dl) was associated with a decline in eGFR of -26.2 ml/min and an increase in urine albumin of 3.26 mg/ 24 h after adjusting for multiple covariables. Furthermore, the multivariable-adjusted odds ratio for CKD comparing the highest tertile (≥131.4 ng/dl) to the two lower tertiles of plasma endostatin was 21.6 (95% CI: 10.2-45.5; p < 0.0001)., Conclusion: These data indicate that elevated plasma endostatin is strongly and independently associated with CKD. Prospective cohort studies and clinical trials are warranted to further examine the causal relationship between endostatin and risk of CKD and to develop novel interventions targeting circulating endostatin aimed at reducing CKD risk., (Copyright © 2012 S.

- Abstract
Vaccinations are available for primary prevention of many infections in adults. Morbidity and mortality from invasive diseases such as influenza and Streptococcus pneumoniae (pneumococcus) remain high and may be largely preventable by vaccination of high-risk adults, including dialysis patients. The current 23-valent vaccine-efficacious, with a low adverse event profile-is widely available. Revaccination is also recommended in patients with immunocompromising conditions, including chronic kidney disease. Despite having many opportunities to be vaccinated, adult hemodialysis and peritoneal dialysis patients are often missed During the recent H1N1 influenza outbreak, we conducted a performance improvement project to increase the vaccination rates for pneumococcal pneumonia, hepatitis B, and influenza, with a special focus on prevention. The project included an education phase, baseline assessment of vaccination rates, intervention, and a follow-up assessment of vaccination rates. The geographic jurisdiction of ESRD Network 13 encompasses the states of Arkansas, Louisiana, and Oklahoma. At the beginning of the network-wide project, the documented state-specific rates for influenza immunization were below the average influenza immunization rates for adults reported by Centers for Disease Control and Prevention and far below its target for adults. Our improvement project incorporated educational interventions to improve patient acceptance of vaccinations, educational interventions to improve staff participation in quality improvement activities, and improved techniques of quality improvement data collection and analysis by participants. During this project, the immunization rates for hepatitis B and pneumococcal pneumonia were also reviewed. At project's conclusion, improvement was demonstrated in all three focus areas, with statistically significant improvements noted in both influenza and pneumococcus vaccination rates. The use of educational interventions to improve staff participation in quality improvement, and the collection and analysis of quality improvement data can be replicated in many practice settings to improve immunization rates for dialysis patients and other patients with chronic illnesses.

- Abstract
The authors developed a reporting tool to assist hemodialysis clinicians to track new arteriovenous fistulas (AVFs), their maturation, and use. The tool identifies impediments to timely use (6 weeks/42 days) of AVFs. The use of this tool in nine dialysis units with high gaps between AVF placement and usage reduced the gap from 19.5% to 13.5% and reflected a reduction in the percentage of AVFs in place but not in use from 31.4% to 23.2%.

- Abstract
Hurricanes Katrina and Rita resulted in massive devastation of the Gulf Coast at Mississippi, Louisiana, and Texas during 2005. Because of those disasters, dialysis providers, nephrologists, and dialysis patients used disaster planning activities to work to mitigate the morbidity and mortality associated with the 2005 hurricane season for future events affecting dialysis patients. As Hurricane Gustav approached, anniversary events for Hurricane Katrina were postponed because of evacuation orders for nearly the entire Louisiana Gulf Coast. As part of the hurricane preparation, dialysis units reviewed the disaster plans of patients, and patients made preparation for evacuation. Upon evacuation, many patients returned to the dialysis units that had provided services during their exile from Hurricane Katrina; other patients went to other locations as part of their evacuation plan. Patients uniformly reported positive experiences with dialysis providers in their temporary evacuation communities, provided that those communities did not experience the effects of Hurricane Gustav. With the exception of evacuees to Baton Rouge, patients continued to receive their treatments uninterrupted. Because of extensive damage in the Baton Rouge area, resulting in widespread power losses and delayed restoration of power to hospitals and other health care facilities, some patients missed one treatment. However, as a result of compliance with disaster fluid and dietary recommendations, no adverse outcomes occurred. In most instances, patients were able to return to their home dialysis unit or a nearby unit to continue dialysis treatments within 4 - 5 days of Hurricane Gustav. Hurricane Ike struck the Texas Gulf Coast near Galveston, resulting in devastation of that area similar to the devastation seen in New Orleans after Katrina. The storm surge along the Louisiana Gulf Coast resulted in flooding that temporarily closed coastal dialysis units. Patients were prepared and experienced minimal interruption of dialysis services. Early planning and evacuation in the face of hurricane landfall--lessons learned from Hurricane Katrina in 2005--prevented disruption of treatment.

- Abstract
Hurricanes Katrina and Rita alerted the world to North America's Gulf Coast's vulnerability to natural disasters. This vulnerability was most evident in poor, minority and elderly populations, and patients with chronic diseases requiring treatment such as dialysis. These hurricanes resulted in massive devastation of the healthcare infrastructure, including dialysis units, across the Gulf Coast region, and often resulted in temporary or permanent closure of dialysis units, predominantly in the New Orleans metropolitan area; however, Hurricane Rita primarily affected Lake Charles. Most notable was the population shift of dialysis patients in Louisiana due to hurricanes Katrina and Rita. Before the 2005 hurricane season, there were 2011 and 362 dialysis patients residing in the parishes (the Louisiana equivalent to counties) most affected by hurricanes Katrina and Rita, respectively. Each of these parishes had experienced increases in dialysis patient populations over the past 5 years. However, following the storms, there were 1014 and 316 dialysis patients residing in the affected parishes. Reasons for the population shifts were multifactorial in nature and included individual, provider, and healthcare system factors. As patients and physicians return to these affected areas, dialysis services will need to be reallocated based on new demographics and distribution of services in Louisiana communities. In planning for future dialysis services, adaptations will need to occur to prevent future interruption of services and loss of patient access to dialysis services.

- Abstract
Hurricane Katrina resulted in massive destruction of the gulf coast of the United States in 2005. In the immediate aftermath, displaced dialysis patients required urgent hemodialysis or additional peritoneal dialysis (PD) supplies. Massive damage to the health care infrastructure in these communities disrupted dialysis services for several months. As a result of this event and subsequent storms during the 2005 Atlantic hurricane season, many decisions regarding future services to dialysis patients in hurricane prone communities (HPCs) need to occur. Nephrologists, dialysis nurses, dialysis providers, and patients need to discuss the ramifications of and types of continued dialysis services in HPC. Nephrologists should encourage PD, and efforts to educate on other renal replacement therapies including PD and transplant should occur. With the potential for interruption of electrical, sewerage, and water services, more patients should consider PD. Recovery from future events begins with appropriate disaster planning. Many questions are considered and need answering in planning for dialysis services in HPC and other communities subject to natural disasters. This summary provides the basis to begin discussions when planning for dialysis services in communities prone to natural disasters.

- Abstract
Cardiovascular disease, the leading cause of death in the United States and other developed societies, can be managed with intensive risk factor modification, including treatment of hypertension and dyslipidemia. Evidence for reduction of cardiovascular morbidity and mortality is summarized in evidence-based guidelines, primarily for hypertension in the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure and for dyslipidemia in the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. Many medications exist for treatment of hypertension and a limited number for dyslipidemia; the cornerstone of therapy for both remains lifestyle modification, including dietary interventions. Despite guidelines, control rates of concomitant hypertension and dyslipidemia remain low. Patient adherence may affect achievement of recommended goals of therapy for dyslipidemia and hypertension. Effective education and communication may improve overall achievement of treatment goals.

- Abstract
Background: Hurricane Katrina resulted in partial or complete devastation of dialysis services throughout the Gulf Coast, including the New Orleans metropolitan area. In the immediate aftermath, dialysis had to be provided to patients by surrounding communities in Louisiana, and ultimately by dialysis programs throughout the nation. Peritoneal dialysis patients, though typically more independent, also endured challenges in continuing dialysis following Hurricane Katrina. Hurricane Rita caused similar damage to the western Gulf Coast at Lake Charles, Louisiana and Beaumont, Texas and further delayed recovery of dialysis services in the New Orleans metropolitan area., Setting: A review of the problems created by the disaster provided many opportunities to improve healthcare delivery and to prepare for recovery from the event. Understanding what happened to the delivery of dialysis and chronic kidney disease services allows the opportunity to develop better systems to support this particularly vulnerable population of patients., Conclusion: Many lessons can be learned from these events to minimize future interruption of dialysis services in the face of natural disasters such as hurricanes.

- Abstract
There have been increasing rates of uninsured patients in the United States over the past few decades. Despite this growing problem, little progress has been made to decrease the rate of growth of uninsured patients or to provide affordable insurance coverage to those who are unable to maintain insurance coverage throughout the year. The legislature in the Commonwealth of Massachusetts has enacted legislation that requires health insurance for all in the same manner that automobile insurance is required in many states. This bold comprehensive legislation augments current Medicaid and state child health insurance program coverage and expands coverage options for part-time workers, those employed by small companies or those employed at lower-income jobs.

- Abstract
On abdominal computed tomography scan for evaluation of hematuria, the index patient, a 23-year-old male, was found to have multiple renal cysts bilaterally. He had been on peritoneal dialysis for 6 years, complicated by intermittent episodes of exit-site infection and peritonitis. Over time, he developed recurrent urinary tract infection and nephrolithiasis with intermittent hematuria. His maintenance dose of recombinant erythropoietin was discontinued, and he maintained a normal hemoglobin level. Annual surveillance of the bilateral renal cysts with magnetic resonance imaging revealed development of a complex cystic mass that warranted further investigation. Following a urology consultation, laparoscopic nephrectomy was performed without complications and with minimal interruption of PD. Pathology evaluation revealed renal cell carcinoma within the renal parenchyma and multiple cystic structures consistent with acquired cystic kidney disease. No clear recommendations exist in the literature regarding continuation or interruption of PD in the perioperative period for planned nephrectomy, tumor resection, or other uncomplicated abdominal or retroperitoneal procedures. A perioperative management strategy for PD patients requiring abdominal or retroperitoneal surgery is outlined here. If these recommendations are followed, patients may continue PD with minimal interruption, preservation of the peritoneal membrane, and few complications.

- Abstract
Because of increased intensity of hurricanes in the Gulf Coast region of the United States, peritoneal dialysis (PD) programs have been disrupted and patients relocated temporarily following these catastrophic events. We describe the disaster planning, implementation, and follow-up that occurred in one such PD program in New Orleans following Hurricane Katrina. Each year at the beginning of the North American hurricane season, the PD program's disaster plan is reviewed by clinic staff and copies are distributed to patients. Patients are instructed to assemble a disaster kit and are provided with contact numbers for dialysis suppliers and for a PD program in their planned evacuation city. In July 2005, this disaster plan was tested when an early tropical storm and hurricane entered the Gulf and several patients briefly relocated or evacuated because of power loss and then returned without incident. However, when Hurricane Katrina, a category 5 storm, was predicted to strike the metropolitan area, patients were notified by telephone to evacuate, and contact information, including their evacuation city and telephone and cellular phone numbers, was obtained. Patients were also reminded to take all medications, bottled water, antibacterial soap, hand sanitizer, and 4-5 days of PD supplies. Following the storm, telephone and cellular phone services were severely disrupted. However, text messaging was available to contact patients to confirm safety and to provide further instructions. Arrangements with the major dialysis suppliers to ship emergency supplies to new locations were made by the PD nurse and the patients. Only 2 of 22 patients required hospitalization because of complications resulting from evacuation failure, contamination, and inability to perform dialysis for a prolonged period of time. Both of these patients were quickly released and have continued PD. Following the event, all patients remained on PD, and most have planned to return to their home PD program. Thorough preparation, planning, practice, and implementation and effective communication are necessary to prevent complications in PD patients who are affected by disasters. With advdnce preparation, maintenance of communication with health care providers, and planning for alternative sites of care, patients can be safely maintained on PD without complications following catastrophic natural disasters.

- Abstract
Infectious complications are the leading cause of morbidity and mortality in peritoneal dialysis (PD) patients. Infectious diseases play a role in the morbidity and mortality of hemodialysis (HD) patients as well. Prevention of transmission of infectious diseases is of paramount importance in any program concentrating on renal replacement therapy, including HD, PD and kidney transplantation. Despite effective means to eradicate infections, increased usage of antimicrobial agents has resulted in antimicrobial resistance. The focus of this paper will be infections in dialysis. Some of the infectious complications discussed here may be applicable to patients with end-stage renal disease who have received a kidney transplant. Prevention of infections in dialysis includes development of infection control strategies by dialysis units with appropriate surveillance strategies. Dialysis staff education, patient education and physician participation is essential for successful infection control in dialysis units. Patients with other chronic infections, such as hepatitis B and human immunodeficiency virus (HIV) infection on dialysis may require additional infection control strategies for dialysis units to prevent infection of other patients and dialysis unit staff. Surveillance and prevention of tuberculosis is part of the comprehensive infection control plan for patients and staff and special considerations may occur for treatment of tuberculosis in other epidemiologic and economic areas of the world. Immunizations, a cornerstone to prevent many infections, have led to decreased morbidity and mortality for many diseases and many immunizations play a role in prevention of disease in dialysis patients.

- Abstract
Infections with Candida species have been associated with significant morbidity and mortality in peritoneal dialysis (PD) patients. Such infections include peritonitis and exit-site infections attributable to Candida species, disseminated candidiasis in immunocompromised patients, and Candida esophagitis. In peritonitis and exit-site infections, both success and failure have been reported with commercially available medications. In disseminated candidiasis and Candida esophagitis, successful treatment and patient recovery depend on the overall nutritional and immune state of the patient. One case each of peritonitis and exit-site infection with non Candida albicans species were successfully treated with oral voriconazole. No literature currently exists on the use of this new product in dialysis patients. Presented here is a treatment strategy that resulted in maintenance of PD in the home setting and catheter survival following completion of treatment. A review of the English-language literature shows mixed outcomes associated with continuation of PD during treatment for Candida infection in PD patients. In conclusion, a commercially available product can be used to successfully treat PD patients who have Candida infections and to maintain the PD catheter for PD.

- Abstract
Health literacy (HL) is the ability to perform the basic reading, writing, and numerical skills required to function in a health care setting. Patients with adequate HL are able to read, interpret, and respond to health care information provided by health care providers and health plans. Several means of assessing HL are available for English- and Spanish-speaking patients. A review of the English-language literature on HL indicated that no prior studies included a subset of peritoneal dialysis (PD) patients. I administered the Rapid Estimate of Adult Literacy in Medicine (REALM) assessment tool to PD patients. I also asked patients for information about their highest education level completed. Following completion of the REALM, patients were classified as having adequate, marginal, or inadequate HL. As other studies have shown, patients with lower levels of education have inadequate HL. Patients with some college education or higher have adequate HL. However, at the average education level of patients, most patients have marginal HL. Relative lack of HL affects a patient's ability to make decisions regarding care as part of a home self-management program for end-stage renal disease (ESRD) and other chronic illnesses. Consequently, relative HL level affects the method of instruction and the time required for instruction during training of PD patients.

- Abstract
We performed a review of United States-based, English-language Web sites to evaluate the information on peritoneal dialysis (PD) available to patients via the Internet. The "hits" obtained after using the search term "peritoneal dialysis" on a series of health care Web sites were listed and reviewed. Information was classified as limited, brief summary, detailed, or extensive, in order of increasing information. Professional organizations dedicated to kidney disease provided extensive information on PD, but Web sites for consumers generally provided little information. Information regarding PD is available to patients on the Internet, but for the most detailed and accurate information, patients should be directed to sites provided by professional organizations that specialize in kidney disease.

- Abstract
Exit-site infections (ESIs) are frequently due to gram-positive organisms and occasionally to gram-negative organisms. Initial empiric antibiotic therapy is therefore directed against these organisms until culture reports are available. Two cases of ESI associated with Mycobacterium are here reported. The first patient, a 63-year-old man with type 2 diabetes, recently treated for Staphylococcus epidermidis peritonitis, presented with acute purulent drainage at the catheter exit site, accompanied by pain and erythema. No tunnel abscess was identified by ultrasound. Empiric antibiotic therapy was initiated with ofloxacin and vancomycin. A rapid-growing acid-fast bacillus (AFB) noted four days after culture was eventually identified as Mycobacterium fortuitum. Ofloxacin was continued, vancomycin was discontinued, and clarithromycin was added. The ESI initially showed improvement; therapy was therefore continued for several months. However, cultures remained positive for M. fortuitum, and the catheter was removed 5 months after therapy was initiated. The second patient, a 28-year-old woman, presented with severe pain and tenderness at the exit site without erythema or drainage. Empiric therapy with cefazolin, gentamicin, and cephalexin was initiated. Gram-positive cocci and an AFB were identified from the exit-site culture, and antibiotics were initially changed to clarithromycin, trimethoprim/sulfamethoxazole, and ofloxacin. The organisms were subsequently identified as M. chelonae-M. abscessus complex and coagulase-negative Staphylococcus. The patient continued to improve after 3 weeks of antibiotic therapy. However, despite the initial improvement in the ESI, the M. chelonae-M. abscessus complex continued to grow, and amikacin was added intravenously. Despite continued treatment, the ESI did not resolve, and the catheter was removed after 4 months of therapy. Despite unusual exist-site infections with rapidly growing AFBs, both patients continued continuous ambulatory peritoneal dialysis (CAPD) while undergoing treatment for ESI. Catheters were left intact, as improvement was initially seen with no evidence of tunnel infection or peritonitis. Rapid-growing AFB should be considered another possible causative agent for ESI. Two cases of atypical mycobacterial exit-site infection are presented to illustrate the difficulties in managing this complication of peritoneal dialysis. Ofloxacin--or other quinolones--may provide a better spectrum of coverage when choosing empiric therapy in patients presenting with ESI.

- Abstract
We report four episodes of non Candida albicans peritonitis (NCAP) in 3 patients on continuous ambulatory peritoneal dialysis (CAPD). Risk factors for NCAP included diabetes mellitus and prior antibiotic use in half of the cases. The antibiotic treatment was prescribed for exit-site infection (ESI) or peritonitis in the patient. Treatment for NCAP included antifungal therapy with oral fluconazole or intravenous amphotericin B. The NCAP resulted in catheter loss in 100% of the patients over time. Initial catheter salvage in one patient was followed 6 months later by catheter loss following treatment of a bacterial peritonitis that was complicated by the development of Candida (Torulopsis) glabrata peritonitis unresponsive to treatment with intravenous amphotericin B. Although the literature suggests that Candida peritonitis responds to oral fluconazole with and without catheter removal, this series suggests that the treatment of NCAP includes removal of the peritoneal dialysis catheter with appropriate antifungal agents.

- Abstract
The index patient is a 23-year-old female with end-stage renal disease (ESRD) secondary to chemotherapeutic agents. Continuous cycling peritoneal dialysis (CCPD) has been the renal replacement therapy for the past 5 years since a failed cadaveric renal transplant. Past medical history was significant for diabetes mellitus, hypertension, anemia, bilateral subclavian vein thrombosis with superior vena cava syndrome, secondary hyperparathyroidism, leukemia (at age 8), and hyperlipidemia. On presentation, soft tissue nodules were noted in the anterolateral surfaces of the legs. After 3 months of continued low-calcium-dialysate CCPD, calcitriol, and oral phosphate binders, a 2 x 3 cm nodule was noted on the posterior aspect of the thorax at the scapula. The only complaint at this time was shoulder pain at the acromioclavicular joint. Radiological examination revealed a 3 x 4 cm soft tissue opacity in the superior segment of the left lower lobe laterally. Despite a prior subtotal parathyroidectomy, phosphate binders, and calcitriol, the parathyroid hormone levels continued to increase, with development of tumoral calcinosis, worsening renal osteodystrophy, and calciphylaxis. Computed tomography examination revealed extensive soft tissue calcification consistent with tumoral calcinosis. An ulcerative lesion (1 cm) developed on the lateral aspect of the upper thigh owing to warfarin necrosis versus calciphylaxis. At this time, the phosphate binder was changed from calcium acetate to sevelamer hydrochloride. Aggressive wound treatment and aggressive calcium and phosphate control added to the treatment regimen has resulted in healing of the single ulcer and a decrease in the size of the tumoral lesions. In conclusion, early recognition and aggressive treatment of calciphylaxis can result in reduced morbidity and mortality from calciphylaxis in ESRD patients.

- Abstract
Only 15 cases of any etiology of Neisseria meningitidis peritonitis have been reported in the world literature since the first case in 1917. We report the first case in a continuous ambulatory peritoneal dialysis (CAPD) patient presenting with abdominal pain and cloudy peritoneal dialysis fluid. A lumbar puncture was normal. The patient died despite therapy with ceftriaxone. Autopsy confirmed this was a case of primary N. meningitidis peritonitis. Of the 15 cases of N. meningitidis reported as a cause of peritonitis, 9 patients were less than age 35 with no underlying diseases. Five cases were associated with cirrhosis or alcohol abuse. Two cases were associated with meningitis, and 1 patient was on steroid therapy for systemic lupus erythematosus. Nine of 15 patients recovered. In conclusion, N. meningitidis should be considered as another rare cause of peritonitis in patients on CAPD.
