  1. If I had Chronic Kidney Disease:What would I want my Doctor to Know….. Liam Plant Department of Renal Medicine, Cork University Hospital Department of Medicine, University College Cork School of Medicine

  2. Conceptual Framework

  3. What happens when kidneys fail? • Conceptually best viewed as loss of nephrons • Conceptually best viewed as not having any dysfunction of the myriad functions of the renal epithelial cells

  4. Where?

  5. (One of the) Central Mechanism(s)

  6. Prevalent ESKD patients (n) 3505 patients 42% HD 5% Home 53% TX 786 p.m.p.

  7. 6 Year Increase in Dialysis Prevalence 31/12/03 – 31/12/09 647 patients 64% All 78% HD 2% PD Mean(95%C.I.) 108 (65,151) All 107 (72,142) HD 1 (-17,19) PD

  8. Identify the Gold Standard Sensible Default

  9. Who gets CKD? • Risk Groups 10% of adults (3-4% CKD 3+) 60% male Older adults Racial Groups Diabetes/Vascular Disease/Other • How detected Screening – which groups Opportunistic Intercurrent Illness Primary presentation

  10. NeoErica project: 112,215 patients (12 practices) • [Creat] in last 10 years - 27.4% – 74% in last 2 years • Proteinuria recorded in 9.1% • 24.9% had eCrClr <60ml/min (C&G) • At least 5.1% of UK population CKD 3-5 • (NHANES-III 4.7% of US population CKD 3-5) Any CKD in adults – up to 10%

  11. Issues • What would I fear………………………………….. • How would I be evaluated………………………… • How would I alter my lifestyle…………………….. • What treatments would I wish……………………… • How would I wish to be monitored and by whom………

  12. What would I fear………..? • Premature death from non-renal complications • Career, financial, family plans • Badly organised care pathways • Pain • ‘Uraemia’ • Renal Replacement Therapy

  13. Theoretical Construct Complications RISK HI-RISK CKD GFR ESKD Death

  14. How would I be evaluated..? • Define presence of CKD • Stratify stage of CKD; estimate rate of progression • Identify underlying cause (specific measures) • Target objectives

  15. Chronic Kidney Disease • One or more of: • Proteinuria • Haematuria (not urological) • Radiological abnormality • Histological abnormality

  16. 5 Key data points • Stage of CKD GFR Hypertension Proteinuria • Complications • Rate of Progression • Comorbidities • Cause of CKD

  17. K/DOQI Stratification

  18. Proteinuria • Dipstick for Screening • 24hr collection if nothing better (worse!) to do • Protein/Creatinine or Albumin/Creatinine ratios • Express as mg/mmol(x0.0088 for 24h) (divide by 100!) • <3.0 Normal • 3.0 – 34.0 Microalbuminuria • >34.0 Proteinuria

  19. How would I alter my lifestyle..? • Stop smoking • Continue drinking • Sensible, healthy diet; passage to ‘elite’ diet only in special circumstances • A BMI target to remember……………..

  20. What treatments would I wish..? • Conservative treatment • Specific treatment • Dialysis therapies • Transplantation • Palliative care

  21. What treatment is appropriate for these patients? ·Review medications. Stop NSAID’s. Adjust other medications if needed because of level of CKD. ·  Treat BP to a target of <130/80. This may require multiple medications. ACEi/ARB are 1st choice therapies. ·   If PCR >300mg/mmol – treat to target of <125/75. ·    If 10year CV risk estimate is >20% - consider anti-platelet agent/statin. ·       Encourage smoking cessation, exercise, weight loss. ·        Immunise against influenza and pneumococcus.

  22. Stage 4-5 drugs • Erythropoeisis-stimulating agents • Drugs for secondary hyperparathyroidism • Anti-rejection drugs

  23. How monitored and by whom..? • Conservative treatment • Specific treatment • Dialysis therapies • Transplantation

  24. Corrigan Club

  25. ‘New Good Practice’ • Renal function expressed as eGFR 4-point MDRD Formula • CKD classified as Stage 1-5 K/DOQI Classification • Protein to Creatinine; Albumin to Creatinine ratio • Detection, monitoring, referral criteria • www.renal.org/CKDguide/ckd.html • Non-visit-based Specialist advice service
