Shun Manabe, Kosaku Nitta, Michio Nagata
Amelioration of podocyte injury, which can lead to podocyte detachment, is the target of therapeutic intervention in glomerular diseases. Since podocytes are terminally differentiated cells with little or no proliferative ability, their loss results in permanent glomerular dysfunction. In immune-mediated glomerular diseases, a variety of immunomodulatory agents are used to maintain podocytes by systemic immunosuppression, which indirectly ameliorates podocyte injury by interrupting the input of immunological stress...

Beta-blockers are frequently used in dialysis patients because of their cardioprotective properties. However, the effect of beta-blockers on reducing dialysis mortality has not been sufficiently examined to date. Thus, we sought to examine the effects on cardiovascular prognosis of beta-blockers using our outpatient dialysis database. From 389 dialysis patients registered in our database, subjects taking beta-blockers were extracted and matched with patients not taking beta-blockers using propensity scores based on 39 variables...

Nephrotic syndrome is a type of intractable disease caused by a disorder in the kidneys, which produces swelling. Although some patients show rapid improvement and recover completely with conventional treatment, many others experience frequent recurrence (frequently relapsing nephrotic syndrome) while some remain dependent on the same high dose of steroids they were initially prescribed at the start of treatment (steroid-dependent nephrotic syndrome). In the latter cases, side effects of prolonged steroid use are a major issue...

Kosaku Nitta, Norio Hanafusa, Ken Tsuchiya
Frailty is a clinical state in which there is an increase in the individual's vulnerability to developing increased dependency and/or mortality when exposed to a stressor. Since the mean age of dialysis patients is increasing worldwide, frailty has recently come to be considered one of the risk factors for mortality in the older dialysis population. The prevalence of frailty among dialysis patients has ranged from 3.0- to 10-fold higher than in community-dwelling elderly, depending on the method of assessing frailty and patient characteristics...

Kidney transplantation represents a renal replacement therapy for end-stage renal failure, with outcomes improving from year to year. With the improved survival prognosis, treatment of complications of chronic kidney disease after transplantation is becoming increasingly important. In particular, posttransplantation anemia (PTA) is often protracted, which could be related to a variety of factors, including the renal function status, graft rejection episodes, and infectious causes. PTA occurs in about 30-40% of transplant recipients, and is known to affect the function of the transplanted kidney as well as patient survival...

Tetsuya Ogawa, Kosaku Nitta
Left ventricular diastolic dysfunction (LVDD) frequently occurs in chronic kidney disease (CKD) and is associated with heart failure and higher mortality. LVDD is observed in patients with early stages of CKD and is associated with cardiovascular events, in patients undergoing incident hemodialysis in the absence of systolic function. The pathogenesis of CKD includes abnormal ventricular filling in diastole and a higher LV filling pressure (LVFP) because of LV hypertrophy (LVH), in addition to myocardial interstitial fibrosis...

Treatment using the cell sheet technology has been applied to various organs, including the cornea, heart, esophagus, periodontium, cartilage, middle ear, and lungs. It has been shown that the therapeutic efficacy of cell sheet transplantation involves 2 aspects, supplementation of cells and provision of cytokines to the affected organ. In addition, cell sheet transplantation also promotes repair of damage through the paracrine effects of cytokines derived from the transplanted cells. It is known that in cases of cell transplantation by injection, the transplanted cells are less likely to differentiate into renal tissue to supply cells, but repair is promoted by the actions of the transplanted cell-derived renotropic factors...

Normal iron metabolism is essential for effective hemoglobin (Hb) production in the management of renal anemia. Considering that studies regarding the optimal Hb levels predated the creation of the iron management indices found in the treatment guidelines for hemodialysis (HD) patients, an increase in the Hb levels caused by intravenous iron supplementation has been used as an iron management index. However, no consideration was given to iron metabolism or the long-term safety of intravenous iron supplementation...

The older dialysis population is growing, and malnutrition and wasting syndrome are great concerns in this population. The management of these syndromes includes appropriate nutritional intake and physical activity. However, whether management in the form of an increase in protein intake has a beneficial effect on muscle mass has not been demonstrated. In this study, we investigated an association between changes of normalized protein catabolic rate (nPCR), as a proxy for protein intake and percent creatinine generation rate (%CGR), as a proxy for muscle mass in patients receiving hemodialysis...

Systemic lupus erythematosus (SLE) is an autoimmune chronic inflammatory disease that affects multiple organs and tissues. Lupus nephritis (LN) is a serious complication of SLE, which occurs at a high rate. Conventional treatment strategies of LN have been widely accepted by two concepts such as induction therapy and maintenance therapy. In LN induction therapy until recently, cyclophosphamide in combination with prednisone (PSL) has been the standard method of treatment for proliferative forms of LN. In the latest review, the combination of mycophenolate mofetil (MMF) is also considered a standard treatment option...

Hereditary cystic kidney diseases are considered as "ciliopathies" caused by abnormalities of the "primary cilia" situated on the tubules. As a result of dysplasia and dysfunction of cilia, formation of cysts occurs at various stages of life. Although occurring at a low incidence, hereditary cystic kidney diseases that develop from the fetal stage to childhood are diverse and are often associated with systemic disorders. The incidence of autosomal dominant polycystic kidney disease, which is the only adult-onset hereditary cystic kidney disease, is the highest among hereditary renal disorders...

Renal prognostic factors of chronic kidney disease are important concerns for patients. Kidney biopsy can be used to evaluate not only the activity of the original disease but also various risk factors related to the lifestyle of patients. Considering that lifestyle-related factors, including obesity and metabolic syndrome, are crucial prognostic risk factors of kidney disease progression and all-cause mortality, evaluation of lifestyle-related prognostic factors in kidney biopsy of all kidney diseases is important...

Minimal change nephrotic syndrome (MCNS) usually responds to steroids but frequently relapses, requiring additional treatment with immunosuppressive agents. Rituximab is a chimeric murine/human monoclonal immunoglobulin G1 antibody that targets CD20, a B-cell differentiation marker. B-cell recovery begins at approximately 6 months following the completion of treatment. Rituximab has a beneficial effect, with the sustained remission or reduction of proteinuria in patients with steroid-dependent MCNS. Relapses are thought to be associated with an increase in CD19 cells...

Takahito Moriyama, Kazunori Karasawa, Kosaku Nitta
BACKGROUND: In the traditional theory of albuminuria, small amounts of albumin pass through the fenestrae in glomerular endothelial cells, then through the slit membrane in the gaps between foot processes of glomerular epithelial cells. In the novel theory, large amounts of albumin pass through glomerular capillaries and are taken up by megalin and cubilin receptors on tubular epithelial cells. These etiologies of urinary albumin excretion are still controversial, and the details of albumin passage through the three layers of glomerular capillaries (glomerular endothelial cells, basement membrane, and epithelial cells) have never been entirely elucidated...

The incidence of the multiple organ dysfunction syndrome (MODS) is rapidly increasing in intensive care units (ICU). It usually combines with sepsis and is the most frequent cause of death in the ICU patients. The nature of the ICU patients has changed in the last years. It includes a variety of patients with severe cases due to major surgical interventions, trauma, hemodynamic instability, sepsis, and so on but also older people than previous times. All these situations can easily lead to MODS. In the prior years, the only available and efficient therapy was renal replacement therapy (RRT) for treating acute renal failure, but the development of technology also gives us devices to support the other systems...

The provision of continuous renal replacement therapy (CRRT) to pediatric patients presents numerous clinical and technical challenges that have been addressed over the past 40 years. Children provide an informative population for acute kidney injury and CRRT study, as pediatric subspecialists practice with a preventive perspective and children often do not have the multiple severe chronic comorbidities that confound adult studies. In addition, the relatively small number of patients treated at any one pediatric center has engendered successful multicenter collaboration to advance the clinical and technical studies of CRRT provision...

Continuous renal replacement therapy (CRRT) is one of the most predominant forms of renal replacement therapy (RRT) currently in use now, this therapy being the initial RRT modality in most critically ill patients. However, in general, the quality of CRRT is still suboptimal. The quality of CRRT is affected by many factors, including the optimal prescription and precision delivery, the CRRT providers' professional level, and the CRRT device used. Establishment of a comprehensive quality control system covering all the aspects and procedures of CRRT is essential...

The continuous renal replacement therapy (CRRT) has offered life-saving treatment for kidney failure. Technological advances coupled with findings from clinical trials have allowed for refinements both in the therapy and in the way it is applied to patients. However, outcomes for patients requiring CRRT remain suboptimal. The use of information technology coupled with structured quality improvement programs offers a methodology for studying the delivery of CRRT with an eye toward improving outcomes. Furthermore, integration of information from the CRRT treatment can be combined with real-time data from other patient-monitoring sources to create "feedback" loops where more timely changes in the CRRT prescription can occur...

Renal replacement therapy (RRT) is a form of extracorporeal support for critical patients, especially for those with acute kidney injury. This therapy enables to gain adequate control over the great metabolic and fluids demand when kidneys are not able to do so; this condition is habitually present in patients who are admitted to intensive care units. However, it is also clear that these patients present a higher mortality rate and, in some cases, complications associated with the therapy. Therefore, it is fundamental to optimize and customize different aspects of RRT that range from the ideal timing including the modality and the dose until its suspension or ending...
