    Is it Hepato-Renal Syndrome? Is it Hepato-Renal Syndrome? Presentation Transcript

    • Mohammed Abdel Gawad Nephrology Specialist Kidney & Urology Center (KUC) Alexandria - EGY drgawad@gmail.com How to Prevent? How to Treat? How to Diagnose? Is it Hepato-Renal Syndrome? 4th KUC Club – May 2014
    • Potentially reversible and functional renal failure In patients with advanced liver failure (acute or chronic) and portal hypertension Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. In the absence of any identifiable causes of renal impairment. A DIAGNOSIS OF EXCLUSION Hepato-Renal Syndrome is:
    • Not all concomitant renal and hepatic impairment is due to the HRS It isn’t even on top of the list A DIAGNOSIS OF EXCLUSION Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318.
    • 4 Levenson D, Korecki KL.. In: Brenner BM, Lazarus JM, eds. Acute Renal Failure. New York: Churchill Livingstone; 1988:535-580. A DIAGNOSIS OF EXCLUSION
    • HRS is a diagnosis of EXCLUSION
    • Increased production or activity of vasodilators (with nitric oxide thought to be most important) Ginès P, Schrier RW. N Engl J Med. 2009;361(13):1279. Iwakiri Y. J Clin Gastroenterol. 2007;41 Suppl 3:S288. Splanchnic Steal Syndrome pooling of blood in the splanchnic vascular bed Pathogenesis of HRS
    • Stadlbauer VP, Wright GA, Banaji M, et al. Gastroenterology 2008;134:111–119. Pathogenesis of HRS
    • Stimulation of Vasoconstrictor System Stadlbauer VP, Wright GA, Banaji M, et al. Gastroenterology 2008;134:111–119. Pathogenesis of HRS
    • Pathogenesis of HRS + Loss of renal autoregulation
    • Pathogenesis of HRS + Loss of renal autoregulation Decrease MAP below the normal range that the autoregulation mechanism can act. Sympathetic mass reflex action
    • Pathogenesis of HRS + Loss of renal autoregulation
    • 12 Pere Ginès, M.D., and Robert W. Schrier, M.D. N Engl J Med 2009; 361:1279-1290
    • 13 Pere Ginès, M.D., and Robert W. Schrier, M.D. N Engl J Med 2009; 361:1279-1290
    • 14 Septic or cirrhotic cardiomyopathy Ginès P, Schrier RW. N Engl J Med. 2009;361(13):1279.
    • HRS is a FUNCTIONAL renal impairment Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. + Loss of renal autoregulation
    • What Is The Prove That The Kidney Is Functionally Normal ? 16 A, Renal angiogram (the arrow marks the edge of the kidney). B, The angiogram carried out in the same kidney at autopsy. Epstein M, Berk DP, Hollenberg NK, et al. Am J Med. 1970; 49:175-185.
    • Precipitating Factors? Who At Risk? Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318.
    • Precipitating Factors? Who At Risk? 18 Fasolato S, Angeli P, Dallagnese L, et al. Hepatology 2007;45:223–229.
    • Precipitating Factors? Who At Risk? 19 The best is to PREVENT the occurrence of HRS
    • How To Prevent? Who At Risk How To Prevent 1- Large volume paracentesis without plasma expansion Give 100 ml 20% human albumin per 1.5L ascities removed 2- Over-Diuresis (weight loss >500g/day for several days in ascitic patient without (or 1kg/day in those with) peripheral edema Judicious use of diuretics, starting with low dose and titrate up slowly. 3- Laxative abuse diarrhea is a dose limiting sign for lactulose 4- GI bleeding Fluid & blood replacement till euvolemia. 5- SBP (any cirrhotic patient + ascities with deteriorating general condition is SBP till proven otherwise) A- antibiotics. B- IV albumin 1.5g/kg at diagnosis and 1g/kg 48hrs later. 6- Alcoholic hepatitis Pentoxifylline (a TNF inhibitor) 400mg tds orally. 7- The use of Nephrotoxic drugs Avoid. 8- Treatment of bleeding and esophageal varices (beta blockers, somatostatin) reduce GFR Monitored carefully
    • 21 A DIAGNOSIS OF EXCLUSION
    • 22 Is it HRS? Yes Which Type? HRS Type 1 HRS Type 2 No Pseudo HRS A DIAGNOSIS OF EXCLUSION
    • Arroyo V, Gines P, Gerbes AL, et al. Hepatology. 1996;23:164-176.
    • Major Diagnostic Criteria Of HRS (All Must Be Present) 1- Presence of liver disease. 2- Presence of renal impairment. 3- In absence of renal cause. 4- In absence of pre-renal cause. 5- In absence of post-renal cause. 24 A DIAGNOSIS OF EXCLUSION
    • • 1- Presence of liver disease: - Chronic or acute liver disease with advanced hepatic failure and portal hypertension • 2- Presence of renal impairment: - Low GFR as indicated by a 24-hr creatinine clearance of < 40 mL/min or serum creatinine > 1.5 mg/dL 25Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. Arroyo V, Gines P, Gerbes AL, et al. Hepatology. 1996;23:164-176. Major Diagnostic Criteria Of HRS (All Must Be Present)
    • 3- In absence of renal cause: 26 Major Diagnostic Criteria Of HRS (All Must Be Present) Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. Arroyo V, Gines P, Gerbes AL, et al. Hepatology. 1996;23:164-176. Imaging: No ultrasonographic findings of parenchymal renal disease. Lab: Proteinuria < 500 mg/dL.History: No exposure to nephrotoxins
    • 4- In absence of Pre-renal cause: 27 Major Diagnostic Criteria Of HRS (All Must Be Present) Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. Arroyo V, Gines P, Gerbes AL, et al. Hepatology. 1996;23:164-176. Absence of Shock Sepsis Volume depletion

Hepatology. 1996;23:164-176. Stop diuretics + Albumin (1 g/kg body weight/day up to 100 g maximum) 1.5 L of normal saline or No sustained improvement in renal function (to creatinine < 1.5 mg/dL or 24-hr CrCl to > 40 mL/min)
    • 4- In absence of Post-renal cause: Major Diagnostic Criteria Of HRS (All Must Be Present) Salerno F, Gerbes A, Gines P, et al. Gut 2007;56:1310–1318. Arroyo V, Gines P, Gerbes AL, et al. Hepatology. 1996;23:164-176. No ultrasonographic findings of obstructive uropathy
    • Take Care !!! Use of CREATININE for Renal Function Estimation In HRS 30Silkensen JR, Kasiske BL. Brenner and Rector’s The Kidney, 7th ed. Philadelphia: Saunders, 2004. Less Reliable Sever hyperbilirubinemia interfers with the Jaffe reaction for creatinine quantitification and may cause low results Renal impairment may be present despite a normal serum creatinine (because these patients are malnourished, with reduced lean body mass)
    • Take Care !!! Use of CREATININE for Renal Function Estimation 31 Serum Cr 2mg/dl Serum Cr 2mg/dl
    • Take Care !!! Use of UREA for Renal Function Estimation In HRS 32 Less Reliable Presence of gastrointestinal bleeding Low hepatic urea production
    • 33 Is it HRS? Yes Which Type? HRS Type 1 HRS Type 2 No Pseudo HRS A DIAGNOSIS OF EXCLUSION
    • Clinical Types of HRS Differentiation
    • 35 Clinical Types of HRS Prognosis Without treatment Median survival time of type 1 HRS is less than 2 weeks Median survival time of type 2 HRS about 6 months Alessandria C, Ozdogan O, Guevara M, et al. Hepatology 2005;41:1282–1289.

Martin-Llahi M, Pepin MN, Guevara M, et al. J Hepatol 2007;46:S36. Wong F. Nat Clin Pract Gastroenterol Hepatol 2007;4:43–51. All patients should receive ALBUMIN 1 g/kg up to 100 g in the first day 20 to 40 g/day afterward
    • Treatment Principles Miscellaneous Vasodilators: • Low-dose dopamine • Prostaglandin E1 analogues (misoprostol) • Endothelin receptor antagonists. No proven efficacy Angeli P, Volpin R, Gerunda G, et al. Hepatology 1999;29:1690–1697. Gines A, Salmeron JM, Gines P, et al. J Hepatol 1993;17:220–226. Wong F, Moore K, Dingemanse J, Jalan R. Hepatology 2008;47:160–168.
    • Treatment Principles Miscellaneous N-acetylcysteine (NAC) in combination with systemic vasoconstrictors or endothelin-receptor antagonists Based on a small case study of 12 patients with HRS who showed an improvement in serum creatinine after intravenous infusion of NAC, but it is not standard clinical practice at this time. Holt S, Goodier D, Marley R, et al. Lancet 1999;353:294–295. Izzedine H, Kheder-Elfekih R, Deray G. J Hepatol 2009;50:1055–1056. Sen S, Mookerjee RP, Jalan R. Gastroenterology 2002;123:2160–2161.

    • Renal Replacement Therapy Hemodialysis has been used as a short-term bridge to liver transplantation. Witzke O, Baumann M, Patschan D, et al. J Gastroenterol Hepatol 2004;19(12):1369–1373. There is no evidence that it increases long- term survival without transplantation.
    • Renal Replacement Therapy UF : Take care of systemic hypotension Filter size: Use small sized filters Anticoagulation: Should be avoided. If needed use LMWH. Catheterization: Right jugular and right femoral veins should be preserved for cannulation when going into bypass at the time of liver transplantation. CVVH is preferred
