Efectos de tests no invasivos (TE) en EHC

-Situación clínica nueva en EHC

-Más pacientes detectados en fases tempranas de cirrosis/cACLD

-No todos son cirróticos

-Recomendaciones de cribaje

Elastografía-cACLDImpacto elastografía-cACLD

¿PORQUÉ cACLD?

-Enmarcar una situación clínica

-Seleccionar pacientes para estudios clínicos y terapeúticos

-Proporcionar recomendaciones de cribaje

cACLD: compensated advanced chronic liver disease

Impacto-elastografía-cACLD

1) Cirrosis es un diagnóstico histológico

2) No siempre hay cirrosis en los pacientes clasificados como F4 por tests no invasivos

3) No hay consenso sobre una definición clínica de cirrosis

4) Pacientes en estadios pre-‐cirróticos pueden tener hipertensión portal

5) Cribaje de HCC puede estar indicada en estadios pre-‐cirróticos

6) Los tests no invasivos han cambiado el escenario clínico de la EHC

¿PORQUÉ cACLD Y NO CIRROSIS?

Impacto elastografía-cACLD

• TE permite identificación en fases tempranas de pacientes con EHC en riesgo de desarrollar CSPH• Término refleja que el espectro de fibrosis grave y cirrosis es un continuo clinicamente indistinguible• cACLD y cirrosis compensada: términos aceptados• Pacientes con sospecha de cACLD: remitir a hepatólogo• TE es suficiente para sospechar cACLD:

• TE útil para identificar CSPH y descartar varices

CONSENSUS STATEMENTS

IDENTIFICATION OF PATIENTS WITH cACLDWHO CAN SAFELY AVOID SCREENING ENDOSCOPY

• Patients with a liver stiffness < 20 kPa and with a platelet count > 150,000 have a very low risk of having varices requiring treatment, and can avoid screening endoscopy (1b;A)

• These patients can be followed up by yearly repetition of TE and platelet count (5;D)

• If liver stiffness increases or platelet count declines, these patients should undergo screening EGD (5;D)

DIAGNOSIS OF CSPH IN PATIENTS WITH cACLD• HVPG measurement is the gold-‐standard method to assess the presence of clinically significant portal hypertension, which is defined as HVPG≥10 mmHg (1b;A)

• By definition, patients without CSPH have no gastroesophageal varices, and have a low 5-‐yr risk of developing them (1b;A)

• In patients with virus related cACLD non-‐invasive methods are sufficient to rule-‐in CSPH, defining the group of patients at risk of having endoscopic signs of PH. The following can be used (2b; B):



DIAGNOSIS OF CSPH IN PATIENTS WITH cACLD (II)• Liver stiffness by TE (≥20-‐25 kPa; at least two measurements on different days in fasting condition; caution should be paid to flares of ALT; refer to EASL guidelines for correct interpretation criteria), alone or combined to Plt and spleen size

• The diagnostic value of TE for CSPH in other etiologies remains to be ascertained (5;D)

• Imaging showing collateral circulation is sufficient to rule-‐in CSPH in patients with cACLD of all etiologies (2b;B)

RESUMEN

-‐Los tests no invasivos (TE) tienen un gran impacto en el manejo de la EHC

-‐El nuevo concepto de cACLD será útil para la práctica clínica y la investigación

-‐El cribado de varices puede evitarse en un grupo substancial de pacientes con cACLD

mediante reglas de clasificación simples utilizando TE y recuento de plaquetas

-‐Mediante la elastografía se puden seleccionar pacientes con CSPH

-‐Otros pruebas no invasivas similares a la TE probablemente sean igualmente útiles

DEFINITION OF COMPENSATED ADVANCED CHRONIC LIVER DISEASE (cACLD)

• The introduction of transient elastography in clinical practice has allowed the early identification of patients with chronic liver disease (CLD) at risk of developing clinically significant portal hypertension (CSPH) (1b;A).

• For these patients, the alternative term “compensated advanced chronic liver disease (cACLD)” has been proposed to better reflect that the spectrum of severe fibrosis and cirrhosis is a continuum in asymptomatic patients, and that distinguishing between the two is often not possible on clinical grounds. (5; D)

DEFINITION OF COMPENSATED ADVANCED CHRONIC LIVER DISEASE (cACLD) (II)

• Currently, both terms : “cACLD” and “compensated cirrhosis” are acceptable. (5; D)

• Patients with suspicion of cACLD should be referred to a liver disease specialist for confirmation, follow-‐up and treatment (5;D)





CRITERIA TO SUSPECT cACLD• Liver stiffness by transient elastography is sufficient to suspect cACLD in asymptomatic subjects with known causes of CLD (1b;A)

• Transient elastography often has false positive results; hence 2 measurements on different days are recommended in fasting conditions (5;D)

• TE values < 10 kPa in the absence of other known clinical signs rule-‐out cACLD; values between 10 and 15 kPa are suggestive of cACLD but need further test for confirmation; values > 15 kPa are highly suggestive of cACLD (1b;A)



CRITERIA TO CONFIRM cACLD• Invasive methods are employed in referral centers in a stepwise approach when the diagnosis is in doubt or as confirmatory tests

• Methods and findings that confirm the diagnosis of cACLDare :– Liver biopsy showing severe fibrosis or established cirrhosis (1a;A); collagen proportionate area (CPA) measurement on histology provides quantitative data on the amount of fibrosis and holds prognostic value (2b;B) and its assessment is recommended (5;D)

– Upper GI endoscopy showing gastroesophageal varices (1b;A)– Hepatic venous pressure gradient (HVPG) measurement; values > 5 mmHg indicate sinusoidal portal hypertension (1b;A)
