Incidence of Acute Pulmonary Edema Before and After the Systematic Use of Ultrasound B-Lines.

Introduction: Acute pulmonary edema (APE) due to fluid overload is considered the most feared complication in hemodialysis patients. Various diagnostic tests have been proposed to assess the fluid status in patients with end-stage kidney failure (ESKF); among these, lung ultrasound (measuring the number of B-lines) is emerging as a promising tool to identify pulmonary congestion in this patient population.

Methods: We compared the incidence of APE before and after the implementation of lung ultrasound as a routine practice in our unit.

Translational Research on Azacitidine Post-Remission Therapy of Acute Myeloid Leukemia in Elderly Patients (QOL-ONE Trans-2).

The achievement of complete remission (CR) is crucial for acute myeloid leukemia (AML) patients undertaking curative therapy, but relapse often occurs within months, highlighting the need for strategies to prolong disease-free survival (DFS). Our phase III study compared the efficacy and safety of azacitidine (AZA) to best supportive care (BSC) in elderly AML patients who achieved CR following intensive induction and consolidation therapy. This ancillary study (QOL-ONE Trans-2) evaluated biological changes in bone marrow using Next-Generation Sequencing (NGS).

Home Pulse Pressure Predicts Death and Cardiovascular Events in Peritoneal Dialysis Patients.

Increased arterial hypertension represents a prevalent condition in peritoneal dialysis patients that is often related to volume expansion. Pulse pressure is a robust predictor of mortality in dialysis patients, but its association with mortality is unknown in peritoneal patients. We investigated the relationship between home pulse pressure and survival in 140 PD patients.

Does Etelcalcetide reverse myelofibrotic bone changes due to hyperparathyroidism? A case report.

Secondary hyperparathyroidism (SHPT) in dialysis is common. A young man on chronic hemodialysis with SHPT developed pancytopenia with resistant anemia requiring transfusions. A bone marrow biopsy showed grade 3 fibrosis, depleted cellularity, osteosclerosis, and decreased myelopoiesis.

Early morning hemodynamic changes and left ventricular hypertrophy and mortality in hemodialysis patients.

Introduction: An exaggeration of the early morning increase in BP, a phenomenon accompanied by a parallel rise in heart rate (HR), is a marker of high cardiovascular risk. The early morning changes in these parameters have not been investigated in the hemodialysis population.

Methods: In a pilot, single center study including a series of 58 patients we measured the pre-awakening BP and HR surges and the nocturnal dipping of the same parameters as well as other established indicators of autonomic function (weighted 24 h systolic BP and HR variability) and tested their relationship with the left ventricular mass index (LVMI) and with the risk of death over a median follow up of 40 months.

A randomized multicenter trial on a lung ultrasound-guided treatment strategy in patients on chronic hemodialysis with high cardiovascular risk.

Lung congestion is a risk factor for all-cause and cardiovascular mortality in patients on chronic hemodialysis, and its estimation by ultrasound may be useful to guide ultrafiltration and drug therapy in this population. In an international, multi-center randomized controlled trial (NCT02310061) we investigated whether a lung ultrasound-guided treatment strategy improved a composite end point (all-cause death, non-fatal myocardial infarction, decompensated heart failure) vs usual care in patients receiving chronic hemodialysis with high cardiovascular risk. Patient-Reported Outcomes (Depression and the Standard Form 36 Quality of Life Questionnaire, SF36) were assessed as secondary outcomes.

Clinical Epidemiology of Systolic and Diastolic Orthostatic Hypotension in Patients on Peritoneal Dialysis.

Blood pressure changes upon standing reflect a hemodynamic response, which depends on the baroreflex system and euvolemia. Dysautonomia and fluctuations in blood volume are hallmarks in kidney failure requiring replacement therapy. Orthostatic hypotension has been associated with mortality in hemodialysis patients, but neither this relationship nor the impact of changes in blood pressure has been tested in patients on peritoneal dialysis.

Reducing salt intake by urine chloride self-measurement in non-compliant patients with chronic kidney disease followed in nephrology clinics: a randomized trial.

Background: Adherence to low salt diets and control of hypertension remain unmet clinical needs in chronic kidney disease (CKD) patients.

Methods: We performed a 6-month multicentre randomized trial in non-compliant patients with CKD followed in nephrology clinics testing the effect of self-measurement of urinary chloride (69 patients) as compared with standard care (69 patients) on two primary outcome measures, adherence to a low sodium (Na) diet (<100 mmol/day) as measured by 24-h urine Na (UNa) excretion and 24-h ambulatory blood pressure (ABPM) monitoring.

Results: In the whole sample (N = 138), baseline UNa and 24-h ABPM were143 ± 64 mmol/24 h and 131 ± 18/72 ± 10 mmHg, respectively, and did not differ between the two study arms.

Treatment-resistant hypertension in the hemodialysis population: a 44-h ambulatory blood pressure monitoring-based study.

Background: Uncontrolled hypertension notwithstanding the use of at least three drugs or hypertension controlled with at least four drugs, the widely accepted definition of treatment-resistant hypertension (TRH), is considered as a common problem in the hemodialysis population. However, to date there is no estimate of the prevalence of this condition in hemodialysis patients.

Method: We estimated the prevalence of TRH by 44-h ambulatory BP monitoring (ABPM) in 506 hemodialysis patients in 10 renal units in Europe included in the registry of the European Renal and Cardiovascular Medicine (EURECAm,), a working group of the European Association, European Dialysis and Transplantation Association (ERA EDTA).

Paget's Disease and Secondary Hyperparathyroidism: Is Healing Possible?

Paget bone disease (PDB) is often asymptomatic and incidentally diagnosed. It is a cause of osteoporosis and bone fragility and exposes patients to a high incidence of bone fractures. In Europe the prevalence varies according to the geographical area of origin, and increases with age.

Long-Term Changes in Sleep Disordered Breathing in Renal Transplant Patients: Relevance of the BMI.

Sleep disordered breathing (SDB), as defined by the Apnea Hypopnea Index (AHI), is a highly prevalent disturbance in end stage kidney disease. SDB improves early on after renal transplantation but long-term changes in AHI in these patients have not been studied. We studied the long-term changes in AHI in a series of 221 renal transplant patients (mean age: 47 ± 12 years; 70% males) over a median follow up of 35 months.

Inflammation is an amplifier of lung congestion by high lv filling pressure in hemodialysis patients: a longitudinal study.

Introduction: Since inflammation alters vascular permeability, including vascular permeability in the lung, we hypothesized that it can be an amplifier of lung congestion in a category of patients at high risk for pulmonary oedema like end stage kidney disease (ESKD) patients.

Objective And Methods: We investigated the effect modification by systemic inflammation (serum CRP) on the relationship between a surrogate of the filling pressure of the LV [left atrial volume indexed to the body surface area (LAVI)] and lung water in a series of 220 ESKD patients. Lung water was quantified by the number of ultrasound B lines (US-B) on lung US.

FGF23 and the PTH response to paricalcitol in chronic kidney disease.

Background: The parathyroid glands are endowed both with receptors responsive to FGF23 and to 1,25 vitamin D. Vitamin D receptor (VDR) activation, besides lowering PTH, also raises serum FGF23. FGF23 has been implicated in parathyroid resistance to VDR activation but the issue has never been investigated in predialysis CKD patients.

Lung ultrasound to detect and monitor pulmonary congestion in patients with acute kidney injury in nephrology wards: a pilot study.

Introduction: Lung congestion and frank pulmonary edema are established complications of acute kidney injury (AKI) and early detection and monitoring of lung congestion may be useful for the clinical management of AKI patients.

Methods: We compared standardized clinical criteria (including lung crackles and peripheral edema grading) and simultaneous chest ultrasound (US) to detect lung congestion in a series of 39 inpatients with AKI.

Results: At baseline, twelve patients (31%) were clinically euvolemic and twelve presented clear-cur cardiovascular congestion (31%) by clinical criteria.

Physical functioning and mortality in very old patients on dialysis.

Background: Old patients with end-stage kidney disease (ESKD) represent an increasing segment of the ESKD population maintained on chronic dialysis treatment. Quality of life (QoL) is notoriously poor in ESKD but relationship between QoL and mortality has not been investigated in the old dialysis population. The objective of this study is to investigate the relationship between QoL and mortality in the old dialysis population.

Etelcalcetide in Patients on Hemodialysis with Severe Secondary Hyperparathyroidism. Multicenter Study in "Real Life".

Etelcalcetide is a new calcimimetic indicated for the treatment of secondary hyperparathyroidism (SHPT) in dialysis patients. Etelcalcetide efficacy in SHPT has been ascertained only in randomized controlled trials. This multicenter study was carried out in "real world" setting that is different from randomized controlled trials (RCTs) to (1) evaluate the effectiveness of etelcalcetide in SHPT, (2) to assess calcium, phosphorus, alkaline phosphatase changes, (3) to register gastrointestinal side effects.

Effects of Sevelamer Carbonate in Patients With CKD and Proteinuria: The ANSWER Randomized Trial.

Rationale & Objective: Hyperphosphatemia is associated with increased risk for chronic kidney disease (CKD) progression and reduced antiproteinuric effects of renin-angiotensin system (RAS) blockers. We investigated whether the phosphate binder sevelamer carbonate may enhance the antiproteinuric effect of RAS inhibitors in patients with CKD.

Study Design: Phase 2, randomized, controlled, open-label, crossover trial.
