The number of patients over 65 years of age with chronic renal failure has increased. Peritoneal dialysis (PD) is an effective mode of treatment for such patients. In the present study, we report our experience with automated PD in patients over 65. We recorded the demographic and clinical characteristics of the patients and the exit-site infection rate, the peritonitis rate, and the mortality rate, comparing those parameters with the same parameters in patients under 65. We followed 36 patients (30% of the total study population) who were over 65 years of age (mean: 74.5 +/- 7.3 years). Of the 36 patients, 34 (94.4%) had another chronic disease--arterial hypertension and heart disease being the more common. Eleven of the patients (31%) had diabetes. Duration of PD therapy in the group was 31.5 +/- 20.7 months. Ten of the patients (27.8%) had at least 1 catheter-related complication, including exit-site infection (n = 3), tunnel infection (n = 1), or a noninfectious complication (n = 6). The rate of catheter-related infection was 0.22 episodes/patient-year. Two catheter were lost: 1 in a case of hematoma, and 1 in a case of catheter obstruction. The rate of peritonitis was 0.16 episodes/patient-year, and the most common infectious agent was methicillin-susceptible Staphylococcus aureus. Actuarial survival of our elderly patients was 51.8% at 4 years of follow-up as compared with 81.7% in the younger patients (p = 0.01). All cases of death were related to comorbid conditions, not to PD therapy. Two patients were transferred to hemodialysis. We conclude that PD has proven to be a safe and comfortable therapy for renal replacement in patients over 65 years of age. Results are similar to results in younger patients.

Clinical trials in urothelial cancer exclude a large population of patients. An observational study evaluated the behavior of frail patients not eligible for cisplatin- or carboplatin-based regimens. Urothelial cancer patients requiring chemotherapy with either chronic renal failure (creatinine clearance <60 ml/min), and/or performance status (PS) > or =2 and/or cardiac dysfunction were prospectively observed. The treatment associated gemcitabine 1200 mg/m and oxaliplatin 85 mg/m, bimonthly (GO). Over 2 years, 31 of 45 (69%) patients with urothelial cancer requiring chemotherapy were not eligible for cisplatin- or carboplatin-based chemotherapy. Sixteen (52%) had a PS > or =2, 23 (74%) had creatinine clearance <60 ml/min, and 20 (65%) had an underlying cardiopathy. A total of 178 cycles of GO were administered (median 6 per patient, range 2-12). No aggravation of renal or cardiac status was noted. Acute grade 3 and 4 neutropenia and thrombocytopenia were observed in 16 and 13% of patients, respectively, with one febrile neutropenia. The median progression-free and overall survival values were 4.2 and 9.5 months, respectively. The majority of urothelial cancer patients have severe renal or cardiac comorbidities, and we conclude that in this subset of patients the combination of gemcitabine and oxaliplatin is well tolerated, and its clinical activity warrants further evaluation.

We report two cases of heterozygous Fabry disease with severe organ damage. Case 1 was a 47-year-old woman. In April 1977, at the age of 27 years, she had proteinuria and edema around the 26th week of her second pregnancy and was diagnosed as toxicosis of pregnancy. She had proteinuria after the delivery. In 1990, a renal biopsy showed zebra bodies under electron microscopic findings, and the patient was diagnosed as Fabry disease. In 1998, a myocardial biopsy showed identical findings. The patient developed severe hypertension and decreased renal function, and alpha-galactosidase enzyme replacement therapy was initiated. However, despite treatment, she was started on dialysis in 2004. Case 2 was a 40-year-old woman. In March 2003, the patient presented with severe hypertension. The patient had cerebral infarction, cardiac hypertrophy, old myocardial infarction and renal failure without diabetes mellitus, hyperlipidemia and collagen disease. The patient was diagnosed as Fabry disease from persistent numbness and pain in the four extremities, a family history of mortality due to heart disease, and skin biopsy findings. She is currently undergoing enzyme replacement therapy. It is generally known that female Fabry disease patients are asymptomatic or mildly symptomatic, as were the present two patients, but some can have marked organ disorders. Hence, even in female patients, it is necessary to consider Fabry disease as a causative disease of chronic renal failure.

There are an estimated 4.1 million people who are classified as American Indian and Alaska Native alone or in combination with one or more other races. This racial group composes 1.5% of the total U.S. population. The leading causes of illness and death among American Indians are heart disease, cancer, unintentional injuries (accidents), diabetes, and stroke. American Indians also have a high prevalence of obesity, chronic renal failure, alcoholism, and are at increased risk for mental health issues and suicide. In an effort to build a trusted relationship with these patients and become an active participant in their care, the health care provider must demonstrate respect for the traditions of the American Indian.

Pulmonary complications are common in patients with chronic renal failure (CRF). The objective of this study was determine the effect of renal transplantation on pulmonary function, using a methacholine challenge test. This interventional study included 14 CRF patients on maintenance dialysis who underwent serial spirometry and astography before and after renal transplantation. None of them was known to have clinically important pulmonary or heart disease. The results of spirometry, astography, echocardiography, and chest X-ray were normal. Five patients were men and all others were women. The overall age range was 15 to 45 years (mean age = 28.6 +/- 10.9). For every patient four times astography was done. The mean values of spirometric and astography indices before and after renal transplantation were within normal limit. But by repeated measure analysis of variance, the results actually showed improved airway responsiveness (although within normal limits). The most common pathological lung condition in CRF is pulmonary edema, usually due to a combination of fluid overload and abnormal permeability of the pulmonary microcirculation. However, our patients had no symptomatic pulmonary edema, but minor degrees of fluid retention are virtually impossible to detect clinically and could not be excluded. Therefore, it seems that disappearance of subclinical pulmonary edema was the likeliest cause of an increase in minimum dose of methacholine, and therefore improvement in airway responsiveness after renal transplantation.

Cardiac transplantation has become an established method for end-stage heart disease. A calcineurin-inhibitor (CNI)-based regimen is the cornerstone of immunosuppressive therapy after cardiac transplantation. CNIs have reduced acute rejection and infection and markedly increased survival of cardiac transplantation patients. However, the dose- and time-dependent nephrotoxic effects of CNIs can limit long-term survival, and chronic renal failure is a major cause of morbidity and mortality in long-term cardiac transplant patients. Early experience on withdrawal of CNIs (and maintenance of patients on azathioprine and steroids) in patients, who developed chronic renal dysfunction, resulted in rejection episodes with, sometimes, fatal outcome. The introduction of newer immunosuppressive drugs, like thymoglobulin, anti CD-25 monoclonal antibodies, mycophenolate mofetil, everolimus or sirolimus into clinical practice, has given transplant physicians new tools to adapt immunosuppression to patients' needs. Changes of immunosuppressive protocols by using new drugs early and late after transplantation and simultaneous reduction or weaning of CNIs have become attractive options. The aim of this article is to review strategies to delay, reduce or prevent CNIs after cardiac transplantation as means to improve short- and long-term outcome mainly by protecting renal function.

Necrotizing fasciitis (NF) is an infection localized at the fascial structures (both the superficial and deep ones) layering the muscles though never affecting them. NF death rate is very high (20-40%). NF can be a post-surgery, traumatic or infective complication and its prognosis quoad vitam is fatal without a timely and correct therapy. A 57-year-old woman was got into observation due to her temperature, left thigh pain, erythema and tumefaction in the left groin-crural seat. She suffered from obesity, insulin-dependent mellitus diabetes and modest but chronic renal failure and ischaemic cardiopathy from previous Acute Myocardial Infarctions. It was then started a wide-spectrum antibiotics therapy. But after just six hours there took place a rapid development of the clinical picture with the appearance of haemorrhagic-content blisters and areas of cutaneous necrosis. The patient therefore underwent-under general anaestesia-multiple incisions in the groin-crural seat and on the ipsilateral thigh. The multiple biopsies carried out during the operation too underwent cultural and histomorphopathological analysis. The anatomic pathological study highlighted the presence of necrosis of the fascia, vascular thrombosis and myonecrosis. The cultural analysis of the tissue biopsies showed a polymicrobial infection. Both the pharmacological therapy and the surgical cleaning were carried out daily but without any improvement of the clinical picture. On the eighth day a worsening of the patient's general conditions took place, with a multiple organ failure determining the patient's exitus.

Diabetes mellitus (DM) and hypertension (HTN) are common risk factors for heart disease in the population. The goal of this study was to evaluate independent association between type 2 DM and HTN using a very large database. We used ICD-9 codes for type 2 DM (250.00, 250.02) and HTN (401.0, 401.1, 401.9) from the Nationwide Inpatient Sample (NIS) database. We randomly selected the years in the database between 1992 and 2002. We used uni- and multi-variate analysis to evaluate any association between type 2 DM and HTN adjusting for co-morbid conditions. The 1992 database contained a total of 6,195,744 patients. Type 2 DM was associated with 37.5% of patients with HTN vs. 11.4% of the control group (odds ratio (OR): 4.63, Confidence interval (CI) 4.61-4.693, p < 0.001). The 2002 database contained a total of 7,853,982 patients. Type 2 DM was associated with 57.2% of patients with HTN vs. 22.9% of the control group (OR: 4.49, CI 4.47-4.52, p < 0.001). Using multivariate analysis adjusting for age, gender, hyperlipidemia, obesity, smoking, and chronic renal failure, type 2 DM remained independently associated with HTN in both years (for the year 1992: OR: 2.49, CI: 2.47-2.51, p < 0.001 and for the year 2002 OR: 2.19, CI: 2.18-2.20, p < 0.001). The same association was persistently found using samples for each year between 1992 and 2002. The presence of type 2 DM is strongly associated with HTN. This association is independent of co-morbid conditions and was persistent with similar odds ratio over a period of 10 years.

The aging process results in remarkable changes in the kidney. These changes are both anatomical and functional and have been considered the cause of the increased propensity of the elderly to acute or chronic renal failure. However, the majority of the early studies on aging enrolled institutionalized elderly patients with several comorbidities such as hypertension and heart disease which could by themselves induce renal alterations. Recently the selection of subjects lacking renal disease or processes known to affect renal function has demonstrated that aging changes are less pronounced in healthy aged subjects. Nonetheless, understanding aging-induced renal changes may help to prevent life-threatening kidney disease. This review will focus on glomerular hemodynamics, and on renal sodium and potassium handling and diluting and concentrating ability.

Currently it is less advanced to understand the pathology of lifestyle disease by using iPS cells because there is partly less direct connection between life style disease and iPS cells. So much more scientists focus on regenerative medicine such as beta cells therapy using iPS cells technologies. It will be indeed a powerful tool to generate beta cells from iPS cells as even in type2 diabetes patients, hyposecretion of insulin from beta cells in pancreas is one of causes. Another reason is complexity of the pathology of life style disease. There are a lot of reasons to cause lifestyle disease. Lifestyle diseases include cancer, chronic liver disease, Type 2 diabetes, heart disease, metabolic syndrome, chronic renal failure, stroke, and obesity. Since obesity is one of major causes of lifestyle diseases, we want to focus on adipogenesis from iPS cells in this review. We analysed and established the differentiation protocol into adipocytes from mouse ES cells and human iPS cells. The other point in this review is the starting pluripotent cells for differentiation. Quality of pluripotent stem cells are one of most critical factors to succeed in getting well-differentiated cells. Recently, we have developed new naive human pluripotent stem cells (PSC),"Reset cells". Naive PSC have more similar to human epibast cells than conventional human PSC. They will be more ideal cells for differentiation because of their hypomethylated status and earlier stage of development.
