3 Cachexia Cachexia is a complex metabolic syndrome associated with underlying illness and characterised by muscle loss, with or without loss of fat Definition of cachexia in chronic illness weight loss of at least 5% within 12 months or Body Mass Index (BMI) <20 kg/m 2 plus three of the following five features: decreased muscle strength; fatigue; anorexia; low fat-free mass index; abnormal biochemistry (increased inflammatory markers [CRP, IL-6], anaemia [Hb <120 g/l], low serum albumin [<32g/L] (Evans et al. 2008).

5 Why is it important to investigate cachexia? Cachexia is linked with poor outcomes for the patients Presence of the cachectic syndrome, associated with any chronic disease trajectory, increases mortality Cachexia causes great morbidity, limits therapy No standardised best treatment for cachexia Lack of guidelines / protocols in clinical practice

12 Health care professionals experience, understanding and perception of need of advanced cancer patients with cachexia and their families: The benefits of a dedicated clinic

13 Study Findings Need to develop specialist communication skills training for healthcare professionals Care of patients with cachexia and their families should employ a multidisciplinary approach Implications for practice: A formal educational cancer cachexia programme for clinicians A dedicated clinic can facilitate a learning environment that allowed best practice to develop across and between professional groups

14 QUB Heritage Importance of the problem: renal disease

15 Importance of problem renal cachexia? Between 30-60% of advanced CKD patients will have cachexia Limited attention has been devoted to cachexia in renal disease For renal cachexia there are no standardised definitions or inclusion criteria to help inform practice or research

16 Management of cachexia Challenging definition needs refinement for renal population Discriminating cachexia from other causes of malnutrition Clinically differentiate between Cachexia and Protein Energy Wasting as each state may require distinct management strategies

22 Establishing A Clinical Phenotype For Cachexia In End-stage Kidney Disease

23 Background Aim: The aim of this study is to determine the clinical phenotype of cachexia specific to individuals with ESKD. Method: This is a longitudinal study which will run over two years. Recruitment: 106 adult haemodialysis patients using a Regional Nephrology Service in the U.K. with a confirmed diagnosis of stage 5 CKD (beginning dialysis at an estimated GFR <15 ml/min/1.73m 2 ). Data Collection: Patients are followed 2 monthly over 12 months and recorded measurements of weight; lean muscle mass (bioelectrical impedance, mid upper arm muscle circumference - from measures of mid arm circumference and tricep skin fold thickness); muscle strength (hand held dynamometer) and increased inflammatory markers (CRP >5mg/L); anaemia (haemoglobin <120 g/l); low serum albumin (<32g/L). Questionnaires: QoL (KDQoL), Fatigue (FACIT) and Anorexia (FAACT) recorded every two months. Primary renal disease, dialysis vintage and co-morbidities (Charlson Comorbidity Index) were also analysed.

31 QUB Heritage Study in collaboration with EDTNA/ERCA

32 Research protocol: Awareness, understanding and treatment practices among health care professionals involved in managing cachexia in patients with End-stage kidney disease. While progress has been made in exploring the awareness, understanding and treatment practices of health care professionals who manage cachexia in other chronic illnesses, no study has explored this for cachexia in renal disease The importance of this work is underscored by the negative impact that symptoms of cachexia have on quality of life and the association of cachexia with a substantially increased risk of premature mortality The study is being conducted with the European Dialysis and Transplant Nurses Association/European Renal Care Association (EDTNA/ERCA) The EDTNA/ERCA is a European network established in 1971 to address the educational needs of nurses and other healthcare professionals caring for patients who suffer from Chronic Kidney Disease. EDTNA/ERCA is a multi-disciplinary organisation with membership open to nurses, technicians, social workers, dietitians, unit managers, transplant coordinators, and other professionals working with patients with kidney disease.

33 A STUDY TO GAIN INSIGHTS INTO THE AWARENESS, UNDERSTANDING AND TREATMENT PRACTICES AMONG HEALTH CARE PROFESSIONALS INVOLVED IN MANAGING CACHEXIA IN PATIENTS WITH END STAGE RENAL DISEASE Survey open to all EDNTA / ERCA members The information will help us understand the management of cachexia in renal disease. Participation is completely anonymous. The survey takes approximately 20 minutes to complete. Membership with EDTNA/ERCA will not be affected whether you choose to participate or not. Return of the questionnaire is considered your consent to participate in this research. Click the link below to be taken to the survey or scan the QR code.

34 Data collection so far. Ongoing survey remains open 1 focus group to complete Survey results so far Responses from 22 countries worldwide Mostly female Excellent range of experience in renal speciality (>50% have over 15 years experience) Lack of certainty about weight loss associated with cachexia Importance of treatment with focus on QoL and family distress Need for disease specific definition to facilitate diagnosis and treatment evident

35 QUB Heritage Renal cachexia research: next steps

36 Definition and intervention A clinical phenotype of cachexia would help to provide early recognition, prevention and timely-appropriate treatment of this devastating condition. Therapeutic approach is dependent on correct classification. Identify to treat Develop an intervention to treat cachexia in renal population Currently no licensed treatment for cachexia in ESRD No accepted standard of care Multi-modal intervention Cachexia is a multifactorial syndrome Lends itself to therapeutic targeting through multimodal treatment

37 Intervention components: Aim - to stop / prevent muscle loss and improve physical function Optimising food intake has been advocated as a key modality in the treatment of cancer cachexia Inflammation is one of the main pathophysiological drivers in cachexia. Thus attenuation of the pro-inflammatory response has been argued as a key component of any cachexia therapy.

38 Qualitative research: enhance person centred care Qualitative research is able to capture the experience of illness, and enables professionals and providers to understand how individuals perceive illness

39 Renal cachexia research: Implications for practice and policy Phenomenon continues to be under-recognised and under-treated in clinical practice Exploring the awareness, understanding and current treatment practices of renal cachexia is currently underway May identify need for similar educational support and development in cancer cachexia Clinical trials (robust pharma and non-pharma) New knowledge gained from this research will inform and develop future care management strategies in the delivery of evidence-based holistic services to this complex patient population Quality Improvement: Implementation of appropriate weight surveillance for clinicians e.g. handgrip strength, BIA? Unaddressed holistic difficulties Role for education?
