Fifteen-minute consultation: Empowering children, young people and families through shared decision-making: a practical guide.

Shared decision-making (SDM) is a collaborative approach to healthcare decision-making that involves patients and healthcare professionals working together to make decisions that are informed by the best available medical evidence, as well as the patient's values, preferences and goals. The importance of SDM and the intricate interplay among parents, children and young people (CYP), and healthcare professionals are increasingly acknowledged as the crucial aspects of delivering high-quality paediatric care. While there is a substantial evidence base for SDM improving knowledge and reducing decisional conflict, the evidence for long-term measures such as improved health outcomes is limited and mainly inconclusive.

A Case of Paediatric Anti-Glomerular Basement Membrane Disease Associated with Thrombotic Thrombocytopenic Purpura.

Anti-GBM disease is a rare vasculitis that causes rapid progressive glomerulonephritis and pulmonary haemorrhage. It is usually an adult diagnosis with isolated paediatric cases reported. Thrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy mainly affecting adults that causes multiorgan ischaemia, microangiopathic haemolytic anaemia, and thrombocytopenia.

Advanced chronic kidney disease among UK children.

Unlabelled: The UK Renal Registry currently collects information on UK children with kidney failure requiring long-term kidney replacement therapy (KRT), which supports disease surveillance and auditing of care and outcomes; however, data are limited on children with chronic kidney disease (CKD) not on KRT.

Methods: In March 2020, all UK Paediatric Nephrology centres submitted data on children aged <16 years with severely reduced kidney function as of December 2019, defined as an estimated glomerular filtration rate <30 mL/min/1.73 m.

UK experience of ofatumumab in recurrence of focal segmental glomerulosclerosis post-kidney transplant.

Background: Steroid-resistant nephrotic syndrome (SRNS), commonly caused by focal segmental glomerulosclerosis (FSGS), is associated with progression to stage 5 chronic kidney disease, requirement for kidney replacement therapy and a risk of disease recurrence post-kidney transplantation. Ofatumumab (OFA) is a fully humanised monoclonal antibody to CD20, with similar mechanisms of action to rituximab (RTX).

Methods: We report a case series of seven UK patients (five paediatric, two adult), all of whom developed FSGS recurrence after kidney transplantation and received OFA as part of their therapeutic intervention.

COVID-19: experiences of lockdown and support needs in children and young adults with kidney conditions.

Background: During the initial COVID-19 pandemic, young United Kingdom (UK) kidney patients underwent lockdown and those with increased vulnerabilities socially isolated or 'shielded' at home. The experiences, information needs, decision-making and support needs of children and young adult (CYA) patients or their parents during this period is not well known.

Methods: A UK-wide online survey co-produced with patients was conducted in May 2020 amongst CYA aged 12-30, or parents of children aged < 18 years with any long-term kidney condition.

Clinical practice guideline management of blood borne viruses within the haemodialysis unit.

Some people who are receiving dialysis treatment have virus infection such as hepatitis B, hepatitis C and/or HIV that is present in their blood. These infections can be transmitted to other patients if blood is contaminated by the blood of another with a viral infection. Haemodialysis is performed by passing blood from a patient through a dialysis machine, and multiple patients receive dialysis within a dialysis unit.

Renal Association Clinical Practice Guideline on Haemodialysis.

This guideline is written primarily for doctors and nurses working in dialysis units and related areas of medicine in the UK, and is an update of a previous version written in 2009. It aims to provide guidance on how to look after patients and how to run dialysis units, and provides standards which units should in general aim to achieve. We would not advise patients to interpret the guideline as a rulebook, but perhaps to answer the question: "what does good quality haemodialysis look like?"The guideline is split into sections: each begins with a few statements which are graded by strength (1 is a firm recommendation, 2 is more like a sensible suggestion), and the type of research available to back up the statement, ranging from A (good quality trials so we are pretty sure this is right) to D (more like the opinion of experts than known for sure).

Validating the use of bioimpedance spectroscopy for assessment of fluid status in children.

Background: Bioimpedance spectroscopy (BIS) with a whole-body model to distinguish excess fluid from major body tissue hydration can provide objective assessment of fluid status. BIS is integrated into the Body Composition Monitor (BCM) and is validated in adults, but not children. This study aimed to (1) assess agreement between BCM-measured total body water (TBW) and a gold standard technique in healthy children, (2) compare TBW_BCM with TBW from Urea Kinetic Modelling (UKM) in haemodialysis children and (3) investigate systematic deviation from zero in measured excess fluid in healthy children across paediatric age range.

The incidence of pediatric acute kidney injury is increased when identified by a change in a creatinine-based electronic alert.

A prospective national cohort study was undertaken to collect data on all cases of pediatric (under 18 yrs of age) acute kidney injury (AKI) identified by a biochemistry-based electronic alert using the Welsh National electronic AKI reporting system. Herein we describe the utility and limitation of using this modification of the KDIGO creatinine-based system data set to characterize pediatric AKI. Of 1,343 incident episodes over a 30-month period, 34.

Aminoaciduria in the prediction of ifosfamide-induced tubulopathy after childhood cancer: a feasibility study.

Background: Ifosfamide, an alkylating agent used widely in the treatment of childhood malignancy, can cause many side effects including a proximal tubulopathy. Studies suggest that aminoaciduria is seen most commonly of all the biochemical abnormalities of ifosfamide-induced tubulopathy. A recent systematic review has found a paucity of data regarding the value of early markers indicating clinically significant tubulopathy.

Positive trends in paediatric renal biopsy service provision in the UK: a national survey and re-audit of paediatric renal biopsy practice.

Background: Paediatric renal biopsy standards introduced in the UK in 2010 were intended to reduce variation and improve practice. A concurrent national drive was aimed at building robust paediatric nephrology networks to ensure services cater for the needs of the family and minimise time away from home. We aimed to identify current national practice since these changes on behalf of the British Association for Paediatric Nephrology.

Dyslipidaemia in children on renal replacement therapy.

Background: Information on lipid abnormalities in end-stage renal disease (ESRD) mainly originates from adult patients and small paediatric studies. We describe the prevalence of dyslipidaemia, and potential determinants associated with lipid measures in a large cohort of paediatric ESRD patients.

Methods: In the ESPN/ERA-EDTA registry, lipid measurements were available for 976 patients aged 2-17 years from 19 different countries from the year 2000 onwards.

Pseudohypoaldosteronism type 1: clinical features and management in infancy.

Unlabelled: Type 1 pseudohypoaldosteronism (PHA) is a rare heterogeneous group of disorders characterised by resistance to aldosterone action. There is resultant salt wasting in the neonatal period, with hyperkalaemia and metabolic acidosis. Only after results confirm isolated resistance to aldosterone can the diagnosis of type 1 PHA be confidently made.

Bilateral progressive cystic nephroma in a 9-month-old male infant requiring renal replacement therapy.

We report the case of a 3-year-old boy who presented at 9 months of age with abdominal distension and was found to have a triad of bilateral cystic nephroma, pleuropulmonary blastoma (PPB) and juvenile intestinal polyps. There have been three previous reported cases of patients with the same associated diagnoses. Our patient is the first reported patient with PPB who received renal replacement therapy and progressed to successful renal transplantation.

A systematic review of the accuracy and utility of early markers of Ifosfamide-induced proximal tubulopathy in survivors of childhood cancers.

This study was conducted to identify and assess the accuracy and utility of any early markers of clinically significant proximal tubulopathy in children treated with ifosfamide chemotherapy. Ifosfamide is widely used either as a solitary agent or in conjunction with various other chemotherapeutic agents in treating solid tumors of childhood. It is highly effective but can cause short-term and long-term damage to kidneys, most commonly resulting in a tubular nephropathy and/or glomerular dysfunction.

A novel tool for B-cell tolerance research: characterization of mouse alloantibody development using a simple and reliable cellular ELISA technique.

In animal-based transplantation research, the measurement of anti-donor antibodies in transplant recipients is limited by lack of an appropriate technique. We have developed a novel immunoassay capable of quantifying antibody bound to cell-surface major histo- compatability complex (MHC) and non-MHC antigens, using splenocytes from wild-type and MHC-deficient mice as antigen-bearing target cells. We utilized our "cellular ELISA" (CELISA) technique to study the development of tolerance versus immunity in the B-cell compartment in response to neonatal exposure to allogeneic fetal liver cells (FLC).

Vascular access survival in children and young adults receiving long-term hemodialysis.

Background: The delivery of long-term hemodialysis therapy in children is complicated by smaller vascular caliber and the potential lifelong requirement for hemodialysis access. Various factors have resulted in the increased use of cuffed central venous catheters (CVLs) in preference to autologous arteriovenous fistulae (AVFs) and arteriovenous synthetic grafts (AVGs). The aim of this study is to compare CVL, AVF, and AVG survival and determine factors affecting their survival.
