A laparoscopic approach represents an effective alternative to open surgery in patients undergoing peritoneal dialysis (PD). In these patients, conventional thinking provides for removal of the peritoneal catheter during left colon resections because of higher risk of patient contamination and peritonitis. The present paper describes 3 cases of laparoscopic left hemicolectomy for colon cancer performed in PD patients without complications and without peritoneal catheter removal, leading to subsequent early PD resumption...

The use of Kt/V to prescribe and monitor hemodialysis adequacy remains the current standard, although it is increasingly questioned. Alternative proposals for dose prescription and monitoring have been advocated. In a noninterventional, prospective study reported in this issue, Maduell et al., utilizing online ionic dialysance, explore the association between outcome measures (mortality and hospitalization rates) and the extent to which delivered Kt dose achieved minimal target Kt doses calculated from individual estimates of body surface area...

Reportedly, citrate-based dialysis solution enables heparin dose tapering or even complete exclusion, particularly in postdilution hemodiafiltration (HDF). The aim of the study was to verify this strategy in predilution setting and to assess its short-term safety, efficacy, and biocompatibility. Ten regular hemodialysis patients were assigned to predilution HDF on acetate- and citrate-based dialysis solutions (0.8 mmol/l trisodium citrate) at random order. Acetate HDF was performed using routine dose of heparin while citrate HDF was heparin free...

Current guidelines focus on conventional dialysis defined as 3-5 hours, three times per week, and suggest that longer or more frequent dialysis be considered. This paper presents the case for considering that shorter or less frequent dialysis should also be considered. More frequent and/or longer dialysis facilitates control of fluid overload, blood pressure, and phosphate levels. These benefits will require time to translate into probable hard outcome improvement. Patients are unlikely to participate in productive or pleasurable activities while undergoing dialysis in center or traveling to treatment...

INTRODUCTION:  C-reactive protein (CRP) is increased among patients on maintenance hemodialysis. Such inflammatory markers can result in protein-energy deficit syndromes and low adequacy of dialysis in these patients. This study evaluated the effect of pentoxifylline on serum CRP level and KT/V in end-stage renal disease patients on maintenance hemodialysis. MATERIAL AND METHODS: This 1-month randomized, double-blind, placebo-controlled clinical trial involving 73 patients with end-stage renal disease on maintenance hemodialysis assessed the effectiveness of 400 mg/d of pentoxifylline on serum CRP level decrease and improvement of dialysis adequacy...

BACKGROUND: Satisfactory vascular access flow (Qa) of an arteriovenous fistula (AVF) is necessary for haemodialysis (HD) adequacy. The aim of the present study was to further our understanding of haemodynamic modifications of the cardiovascular system of HD patients associated with an AVF. The main objective was to calculate using real data in what way an AVF influences the load of the left ventricle (LLV). METHODS: All HD patients treated in our dialysis unit and bearing an AVF were enrolled into the present observational cross-sectional study...

BACKGROUND: Women and small men treated by hemodialysis (HD) have reduced survival. This may be due to use of total-body water (V) as the normalizing factor for dialysis dosing. In this study, we explored the equivalent dialysis dose that would be delivered using alternative scaling parameters matching the current recommended minimum Kt/V target of 1.2. STUDY DESIGN: Prospective cross-sectional study. SETTING & PARTICIPANTS: 1,500 HD patients on a thrice-weekly schedule, recruited across 5 different centers...

INTRODUCTION: Predialysis hypotension has been noted to be a predictor of mortality in hemodialysis (HD) patients. Previous studies evaluating the impact of predialysis hypotension on the mortality of HD patients did not exclude patients with diabetes mellitus (DM) or cardiovascular disease. METHODS: Eight hundred and sixty-six patients on maintenance HD were recruited. Clinical parameters were recorded and subjected to the analysis of predictors of predialysis hypotension and mortality...

Hemodialysis has come a long way since its early days and is a life sustaining therapy for millions of people with end-stage kidney disease throughout the world. Although thrice weekly hemodialysis remains the most common form of renal replacement therapy, other therapies such as more frequent, prolonged dialysis modalities have seen a rise recently. In this review, we compare and contrast methods for measuring the dialysis dose, with a focus on small molecule clearance (Kt/Vurea ) among various dialysis modalities...

BACKGROUND: The publicly available Solute Solver module allows calculation of a variety of two-pool urea kinetic measures of dialysis adequacy using pre- and postdialysis plasma urea and estimated dialyzer clearance or estimated urea distribution volumes as inputs. However, the existing program does not have a 'what if' module, which would estimate the plasma urea values as well as commonly used measures of hemodialysis adequacy for a patient with a given urea distribution volume and urea nitrogen generation rate dialyzed according to a particular dialysis schedule...

The kinetics of uremic solute clearances are discussed based on two categories of uremic solutes, namely those that are and those that are not derived directly from nutrient intake, particularly dietary protein intake. This review highlights dialysis treatments that are more frequent and longer (high-dose hemodialysis) than conventional thrice weekly therapy. It is proposed that the dialysis dose measures based on urea as a marker uremic solute, such as Kt/V and stdKt/V, be referred to as measures of dialysis inadequacy, not dialysis adequacy...

BACKGROUND: Intradialytic hypotension and myocardial stunning are proposed as contributing to the pathogenesis of increased cardiovascular disease burden and death in patients receiving maintenance hemodialysis (HD). Noninvasive cardiac output measurements provide a dynamic, real-time assessment of hemodynamic parameters. We investigated intradialytic changes in hemodynamic parameters in pediatric outpatients receiving chronic HD and determined patient and treatment risk factors associated with such intradialytic changes...

REVIEW
Dirk G Struijk
BACKGROUND: 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. SUMMARY: First the major events in the history of the development of PD are described...

Breath ammonia (NH3) has been proposed as a potential biomarker in monitoring hemodialysis (HD) adequacy, since a strong correlation between blood urea and mouth-exhaled breath NH3 has been observed in patients with end-stage renal disease (ESRD) undergoing HD. However, the biochemical pathways for breath NH3 generation from blood urea have not been demonstrated. In this study, we show a strong correlation (r s  =  0.77, p  <  0.001) between blood and salivary urea, indicating that salivary urea levels reflect blood urea levels...
