AIMS: Depressive symptoms are commonly reported by haemodialysis (HD) patients. Previous reports have suggested an association between depression and nutritional status. To investigate this, we measured muscle mass in HD patients screened for depression. METHODS: The Beck Depression Inventory-II (BDI-II), Hospital Anxiety and Depression Scale (HADS) were used to screen for depression, and quality of life assessed by the short form 36 (SF36), and measured appendicular lean mass (ALM) post-dialysis with segmental bioimpedance...

AIM: The Kidney Disease Improving Global Outcomes (KDIGO) guideline recommends the incorporation of a new risk calculator that quantifies the end stage kidney disease (ESKD) risk based on a composite profile of risk factors in living kidney donor candidates (LKDCs). We compared the ESKD risk estimates in previously declined versus accepted LKDCs to evaluate the predictive capacity and potential impact of this tool. METHODS: Baseline 15-year and lifetime ESKD risk estimates without donation were calculated using the risk calculator for LKDCs assessed from two centres between 2007 and 2015...

BACKGROUND: Risk factors for estimated glomerular filtration rate (eGFR) decline beyond albuminuria are not fully understood in Indigenous Australians who have a 6-fold risk of end-stage kidney disease. We assessed associations between cardio-metabolic risk factors and eGFR decline according to baseline albuminuria status to identify potential treatment targets. METHODS: The eGFR Follow-up study is a longitudinal cohort of 520 Indigenous Australians. Linear mixed regression was used to estimate associations between baseline cardio-metabolic risk factors and annual Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) eGFR change (ml/min/1...

AIMS: Chronic kidney disease (CKD) patients overwhelm specialist services and can potentially be managed in the primary care (PC). Opportunistic screening of high risk (HR) patients and follow-up in PC is the most sustainable model of care. A 'virtual consultation' (VC) model instead of traditional face to face (F2F) consultations was used, aiming to assess efficacy and safety of the model. METHODS: Seventy patients were recruited from PC sites and hospital clinics, and followed for one year...

AIMS: Little is known about postdialysis fatigue (PDF), a debilitating symptom of hemodialysis patients. METHODS: In 5 hemodialysis units of northern-centre Italy, patients were regarded to suffer from PDF if they spontaneously offered this complaint when asked the open-ended question: Do you feel better or worse after dialysis? If worse, please specify in which way. A complaint of fatigue would be probed further with questions directed at its duration, frequency and intensity, allowing creation of a fatigue index of severity (one third of the sum of these three parameters, each rated from 1 to 5)...

AIM: Fibrinogen (Fg) is reported to participate in inflammation through Toll-like receptor 4 (TLR4). However, it remains unknown whether Fg might induce podocyte damage through TLR4 and be related to disease activity in patients with focal segmental glomerulosclerosis (FSGS). METHODS: We observed Fg-induced alterations in actin and apoptosis in cultured human podocytes transfected with or without TLR4 siRNA. Expression of TLR4, phospho-p38 MAPK and phospho-NF-κB p65 was evaluated by quantitative reverse transcription polymerase chain reaction (qRT-PCR) or western blotting, and we analysed urinary Fg levels in adriamycin-treated mice and double immunofluorescence staining for TLR4, Fg and podocin...
