Liver Cirrhosis
Extensive scarring of the liver caused by long-term damage, leading to liver failure, portal hypertension, and severe systemic complications.
Emergency Management: Acute variceal hemorrhage: Requires immediate resuscitation, Octreotide infusion (50 mcg bolus, 50 mcg/hr), IV Ceftriaxone (1g/day) for SBP prophylaxis, and urgent endoscopy (within 12 hours) for banding.
Liver cirrhosis is the late stage of progressive hepatic fibrosis characterized by the distortion of the hepatic architecture and the formation of regenerative nodules. It represents the irreversible end result of various chronic liver insults.
Detailed Overview
Cirrhosis leads to severe hepatic dysfunction and portal hypertension. The loss of functional hepatocyte mass causes synthetic failure (impaired albumin and clotting factor production) and detoxification failure (hepatic encephalopathy). Portal hypertension drives the formation of ascites, esophageal varices, and splenomegaly. It is a major cause of morbidity and is highly predisposed to the development of Hepatocellular Carcinoma (HCC).
Epidemiology & Demographics
Prevalence is approximately 0.15% to 0.27% of the US population. The 10-year mortality rate ranges from 34% to 66%. Higher prevalence in men and individuals aged 45-54.
Etiological Mechanism
The most common causes in the developed world are Chronic Hepatitis C, Alcohol-Associated Liver Disease (ALD), and Nonalcoholic Steatohepatitis (NASH).
Primary Causes
Chronic HCV, excessive chronic alcohol intake, NASH/metabolic syndrome, Chronic HBV, Hemochromatosis, Primary Biliary Cholangitis (PBC), Autoimmune Hepatitis, and Alpha-1 antitrypsin deficiency.
Chronic liver injury leads to hepatocyte necrosis and the release of inflammatory cytokines. Kupffer cells activate hepatic stellate cells in the Space of Disse. Activated stellate cells transition into myofibroblasts and hyper-secrete extracellular matrix, primarily Type I and III collagen. This diffuse fibrosis disrupts the sinusoidal architecture, increasing intrahepatic resistance (portal hypertension). Surviving hepatocytes proliferate to form regenerative nodules, completely distorting liver anatomy.
Diagnostic Criteria & Guidelines
Diagnosed via a combination of clinical, laboratory, and imaging findings. The gold standard is a liver biopsy showing nodular regeneration surrounded by fibrous septa. However, it is clinically diagnosed via non-invasive means like transient elastography (FibroScan stiffness > 12.5 kPa) coupled with compatible labs (thrombocytopenia, prolonged PT/INR).
Management of complications. Ascites: Sodium restriction (<2000 mg/day) and Spironolactone (100 mg PO daily) with Furosemide (40 mg PO daily). Encephalopathy: Lactulose 20-30g PO titrated to 2-3 soft bowel movements daily. Varices: Non-selective beta-blockers (Nadolol 20-40 mg PO daily) or endoscopic band ligation.
Second-Line & Adjunctive Therapy
Refractory Ascites: Large-volume paracentesis with IV Albumin replacement (8g per liter of fluid removed), or TIPS (Transjugular Intrahepatic Portosystemic Shunt). Refractory Encephalopathy: Rifaximin 550 mg PO BID added to Lactulose.
Surgical & Procedural Management
Orthotopic Liver Transplantation is the only definitive cure for decompensated cirrhosis (MELD score > 15).
Patient Counseling & Advice
Warn the patient that cirrhosis is irreversible but its progression can be slowed by removing the insult. Educate on the critical importance of cancer screening and medication adherence to prevent decompensation.
Follow-Up & Monitoring Schedule
HCC screening: Liver ultrasound every 6 months, with or without serum Alpha-Fetoprotein (AFP). EGD every 1-3 years to screen for esophageal varices. Calculate MELD-Na score routinely.
Preventive Strategies
Vaccination against Hepatitis A and B. Aggressive treatment of chronic HCV with direct-acting antivirals. Weight loss and glycemic control for NASH. Alcohol cessation.
Highly dependent on the stage. Measured by the Child-Pugh Score and MELD-Na score. Child-Pugh Class C has a 1-year survival rate of < 50% without transplantation.
