Increase of continuous treatments and regional citrate anticoagulation during renal replacement therapy in the ICUs of the North-West of Italy from 2007 to 2015.

Background: Few reports have addressed the change in renal replacement therapy (RRT) management in the Intensive care Units (ICUs) over the years in western countries. This study aims to assess the trend of dialytic practice in a 4.5-million population-based study of the northwest of Italy.

[Preliminary report on the Covid-19 outbreak in Valle d'Aosta dialysis centers].

Valle d'Aosta, Italy's smallest region, faced a Covid-19 epidemic trend of absolute relevance. In line with data concerning the local general population, the predominance of the illness among uremic patients has been high. The authors report here preliminary data on the spread of this disease within the region and on the clinical trend of the infected patients who needed to be hospitalised.

[Monocentric experience of left atrial appendage occlusion among patients with advanced chronic kidney disease and non-valvular atrial fibrillation].

Atrial fibrillation is the most common cardiac disorder among chronic nephropathic patients. Possible therapeutic approaches include the use of anticoagulants, which are able to reduce the risk of thromboembolism but lead to an increasing bleeding risk, especially in this cohort of patients. Also, novel oral anticoagulant agents (NAO), due to their mainly renal clearance, are a relative contraindication in advanced renal disease.

[Monoclonal gammopathy of renal significance and membranoproliferative glomerulonephritis: a complex relationship with promising therapeutic opportunities].

In the last few years, the increasing awareness of the complex interaction between monoclonal component and renal damage has determined not only a new classification of the associated disorders, called Monoclonal Gammopathy of Renal Significance (MGRS), but has also contributed to emphasize the importance of an early diagnosis of the renal involvement, which is often hard to detect but can evolve towards terminal uraemia; it has also pointed at the need to treat these disorders with aggressive regimens, even if they are not strictly neoplastic. The case described here presented urinary abnormalities and renal failure secondary to a membranoproliferative glomerulonephritis (MPGN), with intensively positive immunofluorescence (IF) for monoclonal k light chain and C3, and in the absence of a neoplastic lympho-proliferative disorder documented on bone marrow biopsy. After the final diagnosis of MGRS, the patient was treated with several cycles of a therapy including dexamethasone, cyclophosphamide and bortezomib, showing a good functional and clinical response.

[Severe multifactorial hyponatremia].

Hyponatremia is the most common electrolyte disorder observed in hospitalized patients. The most severe forms are neurological and potentially fatal emergencies; yet increased morbidity, length of hospital stay and costs associated with less severe forms are aspects of major concern. Nephrologists are frequently consulted regarding the therapeutic management and the key pathophysiological issues of hyponatremia, as this latter aspect represents a true challenge in an emergency setting.

[An unusual case of acute aminophylline intoxication].

Theophylline/aminophylline use for asthma and chronic obstructive pulmonary disease has declined over time, as new and safer therapies developed. However, theophylline/aminophylline overdose can occur. Hereby it is described an unusual case of severe aminophylline intoxication due to mesodermic injections treated with CVVHDF session.

[Metformin- related lactic acidosis].

Lactic acidosis metformin-related is a potentially fatal complication. Reviews show a stable prevalence of this phenomenon, but nephrological experience is required since it is frequently involved in therapeutic management. Here we report the cases of two old patients with severe lactic acidosis and acute renal failure treated with hemodiafiltration.

Self-reported physical activity in patients on chronic hemodialysis: correlates and barriers.

Background And Aims: The knowledge of the barriers that are associated with decreased physical activity (PA) in patients on chronic hemodialysis (PCH) may be of primary importance for the nephrologists. Thus, we aimed to assess the barriers associated with the absent or reduced PA in PCH of a Mediterranean country.

Methods: Patients were invited to answer the question 'How often do you exercise during your leisure time?'.

Clinical risk analysis with failure mode and effect analysis (FMEA) model in a dialysis unit.

Background: The aim of clinical risk management is to improve the quality of care provided by health care organizations and to assure patients' safety. Failure mode and effect analysis (FMEA) is a tool employed for clinical risk reduction. We applied FMEA to chronic hemodialysis outpatients.

Comparison of glucose pump test and urea test in measuring blood access flow.

Background: The Glucose Pump Test (GPT) is a new method for measuring the access blood flow (Qa) based on a constant glucose infusion (Qi), with known glucose concentration (Ci), in the arterial needle and on glucose determination in two blood samples from the venous needle, the first (C1) in basal conditions, the second (C2) during the infusion. Qa depends on the difference in glucose between the two samples and is computed from the formula: QaGPT = Qi x (Ci-C2)/(C2-C1).

Methods: The new method, previously evaluated by ultrasound dilution and color-Doppler techniques, was compared with the Urea Test (UT) in 20 patients measuring recirculation (R) during reversal of the arterial and venous needles (QaUT = Qb x (1/R -1)).

Basiliximab in association with tacrolimus and steroids in caucasian cadaveric renal transplanted patients: significant decrease in early acute rejection rate and hospitalization time.

Safety and tolerability of basiliximab in renal transplantation have been proven in different immunosuppressive regimens. Few informations are available about the association of basiliximab with tacrolimus and steroids. We present a retrospective analysis performed in Caucasian cadaveric renal transplant recipients, comparing a basiliximab, tacrolimus and steroids induction protocol (GrA: 51 patients) with a tacrolimus and steroids protocol (GrB: 46 patients).
