Complications on the feeding artery after an arterio-venous fistula closure in patients after kidney transplantation - a national cohort study.

Background: Arteriovenous fistulas (AVFs) in kidney transplant recipients are sometimes closed, either as a policy or due to complications. We collected data on the incidence of complications after AVF closure in a national cohort of transplanted patients.

Methods: Patients who received a kidney transplant between 2000 and 2015 and had a functional AVF that was later ligated or extirpated were included.

A Pilot Study on the Replacement of Fibrinogen with Fibrinogen Concentrates During Therapeutic Plasma Exchange with Mild to Moderate Bleeding Risk-A Comparison with Fresh Frozen Plasma and Albumin Replacement.

: Therapeutic plasma exchange (TPE) removes coagulation factors and leads to depletion coagulopathy. The aim of the study was to compare hemostasis between TPE procedures without coagulation factor replacement (electrolyte group), the partial replacement of fibrinogen with fibrinogen concentrates (fibrinogen group) and partial coagulation factors replacement with fresh frozen plasma (partial FFP group). : A total of 73 TPE procedures in patients with fibrinogen levels 1-2 g/L were divided into three study groups depending on clinically estimated bleeding risk.

The role of apheresis and insulin therapy in hypertriglyceridemic acute pancreatitis-a concise review.

Severe hypertriglyceridemia (HTG) is the third most common cause of acute pancreatitis (AP) and is involved in its pathogenesis. Chylomicrons increase blood viscosity and induce ischemia, while free fatty acids induce inflammation and distant organ damage. Conservative treatment options include fasting and insulin; limited evidence shows their comparable efficacy.

The Role of Ultrasound Examination in the Assessment of Suitability of Calcified Arteries for Vascular Access Creation-Mini Review.

Arterial calcifications are present in 20-40% of patients with end-stage kidney disease and are more frequent among the elderly and diabetics. They reduce the possibility of arterio-venous fistula (AVF) formation and maturation and increase the likelihood of complications, especially distal ischemia. This review focuses on methods for detecting arterial calcifications and assessing the suitability of calcified arteries for providing inflow before the construction of an AVF.

A matched case-control study on the effectiveness of extracorporeal cytokine adsorption in critically ill patients.

Extracorporeal cytokine adsorption aims to reduce cytokine levels in critically ill patients. However, little convincing data exist to support its widespread use. This retrospective study compared interleukin-6 (IL-6) levels in patients treated with or without cytokine adsorber (CytoSorb®).

Effect of CytoSorb Coupled with Hemodialysis on Interleukin-6 and Hemodynamic Parameters in Patients with Systemic Inflammatory Response Syndrome: A Retrospective Cohort Study.

Excessive release of cytokines during systemic inflammatory response syndrome (SIRS) often leads to refractory hypotension and multiple organ failure with high mortality. Cytokine removal with hemoadsorption has emerged as a possible adjuvant therapy, but data on interleukin-6 (IL-6) reduction and outcomes in clinical practice are scarce. We aimed to evaluate the effect of CytoSorb hemoadsorption on laboratory and clinical outcomes in shocked patients with SIRS.

Doppler ultrasound assessment of calcified radial arteries prior to radio-cephalic arterio-venous fistula placement: an observational study.

Background: In elderly and diabetic patients, arterial calcifications are prevalent and result in worse outcomes of arterio-venous fistulas (AVFs). Optimal ultrasound criteria for assessment of calcified arteries are unknown. We report our experience with ultrasound assessment of calcified arteries prior to placement of radio-cephalic (RC) AVFs.

Comparable Triglyceride Reduction With Plasma Exchange and Insulin in Acute Pancreatitis - A Randomized Trial.

Background And Aims: Both insulin and plasma exchange (PE) are used in hypertriglyceridemic acute pancreatitis (HTG-AP). Our aim was to compare the efficacy of both treatments.

Methods: A randomized, parallel group study performed in a tertiary hospital in 22 HTG-AP patients with non-severe prognosis and triglycerides between 15 and 40 mmol/L.

Extracorporeal Removal of Myoglobin in Patients with Rhabdomyolysis and Acute Kidney Injury: Comparison of High and Medium Cut-Off Membrane and an Adsorber Cartridge.

Introduction: The role of extracorporeal myoglobin removal in the treatment of rhabdomyolysis-associated severe acute kidney injury (AKI) is not yet fully established. High cut-off (HCO) and medium cut-off (MCO) dialysis membrane and cytokine adsorber (CytoSorb®) have been used to this purpose in clinical practice. The data on comparative effectiveness of those methods are scarce.

A national cohort study on hemodialysis arteriovenous fistulas after kidney transplantation - long-term patency, use and complications.

Objective: To describe the long-term hemodialysis arteriovenous fistula (AVF) patency, incidence of AVF use, incidence and nature of AVF complications and surgery in patients after kidney transplantation.

Patients And Methods: We retrospectively analysed the AVF outcome and complications in all adult kidney allograft recipients transplanted between January 1st, 2000 and December 31, 2015 with a functional AVF at the time of transplantation. Follow-up was until December 31, 2019.

Treatment of preeclampsia at extremely preterm gestation with therapeutic plasma exchange.

Aims: Different forms of apheresis have been proposed as potential therapeutic approaches to remove soluble Fms-like tyrosine kinase-1 (sFlt-1) and allow safe pregnancy prolongation in cases of extremely preterm preeclampsia. This is a follow-up study presenting our experiences with therapeutic plasma exchange (TPE) in 5 women with preeclampsia at < 28 weeks of gestational age.

Materials And Methods: All women received standard treatment for preeclampsia and 2 - 3 TPE treatments per week.

Biocompatibility Parameters with Standard and Increased Dose of Citrate in Hemodialysis-A Randomized Trial.

Background: The dose of citrate needed in regional citrate anticoagulation (RCA) to achieve optimal biocompatibility is unknown. We performed a randomized trial comparing two doses (ACTRN12613001340729).

Methods: In 30 patients a single hemodialysis with either standard (2.

Clinical and dialysis-related characteristics of extremely long-term hemodialysis survivors: Three case reports.

More than 40-year hemodialysis survivors are living evidence of the achievements of hemodialysis therapy. We present the case reports of three patients treated by chronic hemodialysis for 47 (Patient 1), 43 (Patient 2), and 42 years (Patient 3) from a single center. These patients possess characteristics that were already shown to be associated with improved long-term survival: initiation of hemodialysis at a young age, absence of diabetes, and a relatively low and stable body weight with good nutritional status.

The possibility of SARS-CoV-2 transmission in a haemodialysis unit - report from a large in-hospital centre.

Data on the possibility of transmission of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) during the provision of chronic haemodialysis, which often entails many person-to-person contacts, are lacking. We report a follow-up of the in-centre contacts of three positive chronic haemodialysis patients. Under strict preventive measures, only one patient out of 21 patient-contacts and 29 personnel-contacts tested positive within 2 weeks after the last contact.

Regional citrate anticoagulation for continuous renal replacement therapy in newborns and infants: Focus on citrate accumulation.

Continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA) in newborns and infants is challenging and accumulation of citrate can occur. There are only a few studies reporting the detailed data on RCA. We aimed to analyze RCA-CRRT at our institution with focus on citrate accumulation.

Distal Arterial Embolization from an Abandoned Native Brachio-Cephalic Fistula: A Case Report.

Abandoned thrombosed arterivenous fistulas are usually left in place with very rare complications. We describe a case of distal embolization from a thrombosed aneurismatic arteriovenous brachiocephalic fistula in a patient who vigorously used the affected arm for pushing his wheelchair. Vigorous physical activity with the hand bearing arteriovenous fistula (AVF) should probably be discouraged even after AVF thrombosis and especially, if the initial part of fistula vein is aneurysmatic.

Anticoagulation assessment methods in plasma exchange with regional citrate anticoagulation: evaluation of post-filter and filtered plasma ionized calcium.

Aim: To assess the possibility of using filtered plasma instead of postfilter ionized calcium (iCa) for the assessment of anticoagulation in plasma exchange (PE) with citrate anticoagulation.

Methods: 140 PE treatments were performed using either 4% or 15% citrate at a comparable dose. Paired samples of postfilter blood and filtered plasma were taken for iCa measurements with a point-of-care analyzer.
