2. INTRODUCTION
⢠Chronic liver disease (CLD) is a major cause of mortality and morbidity
worldwide, accounting for approximately 2 million deaths per year.
Moreover, there has been a 46% increase in cirrhosis mortality in the
world from 1980 to 2013.
⢠Currently, cirrhosis and liver cancer cause 1.16 million and 788,000
deaths per year globally, respectively, making them the 11th and 16th
most common causes of death, respectively.
⢠Together, they are responsible for 3.5% of all deaths worldwide.
3. ⢠Definition
Cirrhosis of Liver
⢠Cirrhosis of liver with portal hypertension was diagnosed based
on standard clinical feature (presence of ascites, shrunken liver,
splenomegaly, and dilated epigastric veins), radiological evidence
(shrunken liver, dilated portal vein with periportal, or other
collaterals), and/or endoscopic evidence (presence of
esophageal/gastric/ectopic varices)
4. Etiology of cirrhosis of liver
⢠chronic hepatitis B
⢠chronic hepatitis C
⢠ALD was presumed in subjects who reported excessive alcohol use (60â
80 g alcohol per day for men, 40â60 g per day for women for 10 years
or more) and had increased serum aminotransferase levels without
other causes of liver disease.
⢠Nonalcoholic steatohepatitis (NASH)-related cirrhosis.
⢠cirrhosis along with diabetes mellitus or obesity (BMI >25).
⢠Wilsonâs disease, autoimmune hepatitis, and primary biliary cirrhosis .
⢠(No etiology ascertained) cryptogenic cirrhosis.

Entecavir plus HAART is also an option
⢠Preferred: Truvadac or tenofovir plus entecavir
⢠a The upper limits of normal for serum ALT concentrations are 30 IU/L
for men and 19 IU/L for women.
⢠b Upon initial diagnosis, monitor every 3 months for 1 year to ensure
stability.
⢠c Truvada is the trade name for emtricitabine 200 mg and tenofovir
disoproxil fumarate 300 mg.
15. Variceal hemorrhage
⢠Resistance to portal blood flow and increased portal venous blood
inflow result in the reversal of flow and formation of alternate blood
flow channels between the portal and systemic circulation, which
result in varices. The development of varices acts as a surrogate
marker of PH and signifies clinically significant portal hypertension
(CSPH).
16. ⢠HVPG is the closest surrogate marker of actual portal pressure and
PH, with the presence of PH being defined as an HVPG > 5 mm Hg,
while a value of >10 mmHg signifies CSPH.
17. Management of acute variceal bleeding
⢠Hemodynamic resuscitation
⢠Fluid resuscitation should be cautious and restrictive to keep
hemoglobin between 7 and 9 gm/dl
⢠Adequate purging should be done to prevent post-bleed sepsis, HE,
ascites, or other complications of PH.
⢠Post-bleed sepsis can increase mortality; thus mandating the use of
antibiotics during bleeding events as per local antibiograms i.e.,
third-generation cephalosporins are recommended (ceftriaxone 1 gm
IV every 24 h for 7 days).
⢠Vasoconstrictors like Somatostatin, octreotide, and terlipressin are
the recommended agents, for 4-5 days.
⢠Endoscopy-based endotherapy is definitive in managing VH and
should be done within 12 h after hemodynamic resuscitation.
18.
19. Primary prophylaxis of VH
⢠Non-selective beta-blockers (NSBBs) Propranolol or EBL are
the treatments of choice to prevent VH.
⢠They have pleiotropic effects, like preventing bacterial
translocation, antioxidant properties, containing further non-
bleed decompensations, and portal hypertensive gastropathy
progression, as well as improving survival in ACLF.
⢠Rate-controlling agent, ivabradine(reducing the incidence of
acute kidney injury (AKI) and HE, and achieving a target heart
rate ).
20. ⢠Carvedilol was introduced, which has a better profile than
propranolol. The addition of carvedilol to EBL than propranolol
to EBL can lead to better HVPG response
⢠Early TIPSS (stent placement within 5 days of variceal bleed)
has shown significant mortality benefits.
⢠EUS-guided glue injection with or without coiling is safe and
effective in primary and secondary prophylaxis of gastric varices
bleeds .
⢠Recent studies suggest performing TIPSS with BRTO in
patients with recurrent variceal bleeding and spontaneous
portosystemic shunts (SPSS) to prevent HE .
21. Ascites
⢠Most common complication of cirrhosis, and PH develops in
~85% of the cases.
⢠ascitic fluid analysis is recommended, including serum-ascites
albumin gradient (SAAG). SAAG value ⼠1.1 g/dL has 97%
sensitivity for PH as a cause of ascites
22. Management
⢠sodium restriction (salt intake of < 5 g)
⢠judicious use of diuretics
⢠Use of albumin replacement and increased oral protein intake
helps ascites mobilization
⢠midodrine for a short course can control ascites better than
diuretics alone, with a lesser occurrence of diuretic
complications.This is contraindicated in patients with RA
requiring LVP due to compromised cardiac performance
23.
24. Refractory Ascites
⢠A weight loss of < 0.8 kg over 4 days in a patient with cirrhosis on
intensive diuretic therapy for at least 1 week is termed diuretic-
resistant ascites, provided the urinary sodium is less than the sodium
intake/day.
⢠The recommended full dose of diuretics (160 mg of furosemide and
400 mg of spironolactone) is rarely reached as most patients
develop adverse events with higher recommended doses, which is
called diuretic-intractable ascites.
⢠The diuretic intolerance in the Asian population is due to a higher
incidence of sarcopenia, poor muscle reserve, and a higher
occurrence of diuretic-related complications, including renal injury
and electrolyte imbalances .
25. ⢠Refractory ascites needs hepatocellular carcinoma, portal vein
thrombosis, and infection of the peritoneum [sepsis, spontaneous
bacterial peritonitis (SBP)/Non-SBP/tuberculosis] to be ruled out.
⢠An elevated ascitic fluid protein content of more than 2â2.5 g/dl is
suggestive of tuberculous ascites. Adenosine deaminase (ADA)
and gene x-pert (tuberculosis nucleic acid testing) analysis of
ascitic fluid is suggested in all patients with cirrhosis with
difficulty uncontrolled ascites before labeling them as RA.
⢠Large-volume paracentesis (LVP > 5 L) with albumin infusion (8
gm/L of ascites removed) is the recommended therapy to
relieve the symptoms.
26. ⢠Midodrine was reported as superior to albumin in preventing PICD .
⢠Rifaximin, reduces endotoxemia.
⢠Tolvaptan is beneficial in ascites control with survival benefit (can cause or
precipitate bleeding episodes by platelet aggregation inhibition and
depleting vitamin-K-dependent clotting factors and has a risk of liver
injury)- restrictive to patients of grade 3 ascites/RA with refractory
hyponatremia and should be used for the shortest duration possible.
⢠Terlipressin, the most used drug in hepatorenal syndrome (HRS) and RA,
helps in ascites control by mobilizing ascites and increasing renal
perfusion, glomerular filtration rate (GFR), and urinary sodium excretion .
⢠Long-term albumin administration in patients with ascites improves
survival, decreases hospitalization, and reduces overt HE, ascites, SBP,
and non-SBP infections
â˘
27. TIPPS
⢠Careful selection of patients for TIPSS after a proper cardiac
evaluation is recommended. A patient with age < 70 years with
preserved liver function tests and low severity scores (MELD <
18 and Child score < 8) without any history of HE in the
preceding 6 months are candidates suitable for TIPSS.
28. Newer perspectives
The automated low-flow ascites pump (ALFA) system, a novel
device that transfers ascites from the peritoneal cavity to the
urinary bladder, is effective in patients with RA.
Not universally available, complicated to use, and has higher
adverse events; therefore, its use is currently limited.
Sodium-glucose co-transporter 2 inhibitors (SGLT2I) increase
sodium and glucose excretion in the urine and decrease renin
secretion, showing significant improvement in ascites besides
glycemic control in a few small studies
29. Hepatic encephalopathy
⢠HE in a patient with acute liver failure is termed type A, while
those related to shunts are termed type B, and those with
cirrhosis are termed type C. HE is graded as per West-Haven
criteria. HE can be covert [minimal HE (MHE) and Grade I HE],
which needs to be identified with the help of specialized
neuropsychological tests. Covert HE is reported among 80% of
patients with advanced liver disease, while overt HE is reported
among 40%.
30. ⢠Overt HE can be new onset, episodic, with an interval between
episodes of >6 months, or recurrent, where further episode
occurs within 6 months. Persistent HE refers to an uncommon
entity with no resolution of HE. Refractory HE (lack of response
after treatment of precipitants and on treatment with lactulose
and rifaximin for 48 h) is an uncommon but serious condition
and requires active investigation into hidden precipitating events
(i.e., portosystemic shunt) and requires alternative diagnosis to
be ruled out (87). Important alternative causes include septic
encephalopathy (23%), alcohol withdrawal, seizure,
dyselectrolytemia, metabolic disorders, drugs/toxins (7%),
intracranial structural lesions (5%), psychiatric disorders (1%),
and multiple causes together (8%).
31. Management strategies in HE
⢠Correct identification of the precipitant is the key to the
management of HE.
⢠Non-absorbable disaccharidases (lactulose/lactitol) are the first-
line therapy. Adding polyethylene glycol to non-absorbable
disaccharidases leads to earlier, sustainable improvement in HE
with survival benefits (94). Studies have shown a positive role of
rifaximin and intravenous L-ornithine L-aspartate (LOLA) in
overt HE management .
32. ⢠Adequate calories (35â45 kcal/kg/day) and protein (1â1.5
gm/kg/day) .
⢠Rifaximin is an oral antibiotic with minimal absorption (< 0.4%),
broad-spectrum activity against enteric bacteria. Should be
used in conjunction with lactulose.
⢠zinc supplements.

33. Newer perspectives
⢠Ammonia-lowering agents (Phenylacetate, Phenylbutyrate, and
Sodium Benzoate) and drugs affecting neurotransmission (flumazenil
and bromocriptine) have been reported to be effective but are rarely
used.
⢠L-ornithine L-aspartate
⢠Fecal microbiota transplantation (FMT) or intestinal microbiota
transplantation is a feasible and safe option for patients with
recurrent or persistent HE
⢠FMT restores the altered gutâliverâbrain axis
