Following the introduction of a causative agent into the body, such as toxins or certain viral infections, a cascade of events unfolds within the liver, initiating an acute inflammatory response. This inflammatory reaction triggers hepatic vascular occlusion, resulting in reduced blood flow to the liver and subsequent ischemia and hypoxia of hepatic tissue. Ischemia, characterized by inadequate blood supply, sets the stage for the progression of hepatocellular injury and necrosis, as vital oxygen and nutrients are deprived from hepatocytes, the functional cells of the liver.

The ischemic insult leads to widespread damage and death of hepatocytes, culminating in hepatic necrosis. As the liver tissue undergoes necrosis, it releases pro-inflammatory cytokines and other toxic substances into the bloodstream, exacerbating the inflammatory response and further compromising liver function. This cascade of events not only disrupts the liver’s ability to perform its vital functions, such as detoxification and metabolism, but also contributes to the development of hepatic encephalopathy, a serious complication characterized by altered mental status and cognitive impairment.

Despite advancements in medical care and supportive therapy, fulminant hepatitis remains a life-threatening condition with a remarkably high mortality rate ranging from 60% to 85%. Even with intensive treatment measures aimed at stabilizing the patient, managing complications, and supporting liver function, many individuals with fulminant hepatitis fail to survive. The rapid and severe nature of the liver injury, combined with the challenges of managing complications such as hepatic encephalopathy and multi-organ dysfunction, underscores the urgent need for early recognition, prompt intervention, and aggressive management strategies in the care of patients with this devastating condition.

Signs and Symptoms

Jaundice: Jaundice, characterized by yellowing of the skin and sclerae, occurs due to the accumulation of bilirubin in the bloodstream as a result of impaired liver function.
Frothy Urine: Urine may become frothy when shaken, indicating the presence of proteinuria, a common finding in patients with fulminant hepatitis due to renal dysfunction.
Pruritus: Pruritus, or itching, may occur as bile salts accumulate in the skin due to impaired excretion, causing irritation and discomfort.
Steatorrhea and Diarrhea: Poor absorption of fats and nutrients in the gastrointestinal tract can lead to steatorrhea (fatty stools) and diarrhea, contributing to malnutrition and weight loss.
Peripheral Edema: Peripheral edema, characterized by swelling of the extremities, may develop due to hypoalbuminemia and decreased oncotic pressure, leading to fluid accumulation in interstitial spaces.
Ascites: Ascites, the accumulation of fluid in the peritoneal cavity, is a common complication of fulminant hepatitis, resulting from portal hypertension secondary to liver dysfunction.
Bleeding Tendencies: Coagulopathy, manifested by easy bruising, petechiae, or mucosal bleeding, can occur due to impaired synthesis of clotting factors and decreased production of proteins by the damaged liver.
Altered Mental Status: Patients may experience irritability, confusion, or coma as hepatic encephalopathy develops, resulting from the accumulation of toxic substances, such as ammonia, in the bloodstream due to impaired liver clearance.
Fever: Fever may be present in some cases of fulminant hepatitis, especially if there is an underlying infectious etiology or systemic inflammatory response.
Hepatic Coma: Hepatic coma, a severe manifestation of hepatic encephalopathy, is characterized by profound alterations in consciousness, ranging from confusion to coma, and requires urgent medical attention.

Management

History:

Medical History:

Obtain a detailed medical history, including past medical conditions, medications, and previous episodes of liver disease.
Inquire about potential risk factors for hepatitis, such as intravenous drug use, unprotected sexual activity, recent travel to endemic regions, or occupational exposures to hepatotoxic substances.

Symptom Assessment:

Ask about the onset and duration of symptoms, including jaundice, abdominal pain, nausea, vomiting, fatigue, and changes in mental status.
Inquire about associated symptoms such as pruritus, diarrhea, dark urine, and pale stools, which may suggest liver dysfunction or complications of fulminant hepatitis.

Exposure History:

Assess for potential exposure to infectious agents, toxic chemicals, herbal supplements, or medications known to cause liver injury.
Determine the patient’s alcohol consumption history, as excessive alcohol intake can exacerbate liver damage and contribute to the development of fulminant hepatitis.

Family History:

Inquire about a family history of liver disease, autoimmune disorders, or hereditary conditions that may predispose to liver dysfunction, such as Wilson’s disease or hemochromatosis.

Physical Examination:

General Examination:

Assess the patient’s vital signs, including temperature, blood pressure, heart rate, and respiratory rate, to evaluate for signs of systemic illness or hemodynamic instability.
Evaluate the patient’s general appearance, noting signs of jaundice, pallor, or cachexia suggestive of underlying liver disease.

Abdominal Examination:

Palpate the abdomen to assess for hepatomegaly, splenomegaly, or tenderness, which may indicate liver inflammation, congestion, or enlargement.
Percuss for the presence of ascites, eliciting shifting dullness or a fluid wave, suggestive of fluid accumulation in the peritoneal cavity.

Skin and Mucosal Examination:

Inspect the skin and sclerae for signs of jaundice, characterized by yellow discoloration, and assess for evidence of pruritus, ecchymoses, or petechiae suggestive of coagulopathy.
Examine mucous membranes for signs of bleeding or mucosal lesions, which may indicate underlying liver dysfunction or systemic complications.

Neurological Examination:

Perform a focused neurological assessment, including mental status evaluation, orientation, cognitive function, and assessment of motor and sensory function, to screen for hepatic encephalopathy or neurological complications.

Laboratory Investigations:

Order laboratory tests, including liver function tests (serum transaminases, bilirubin, albumin, and coagulation profile), a complete blood count, renal function tests, and viral serology (for hepatitis viruses), to assess liver function, detect metabolic abnormalities, and identify potential infectious etiologies.

Imaging Studies:

Consider abdominal ultrasound or computed tomography (CT) imaging to evaluate liver morphology, assess for the presence of hepatic lesions or vascular abnormalities, and detect signs of portal hypertension or ascites.

Additional Investigations:

Depending on the clinical presentation and suspected etiology, additional investigations such as viral serology, autoimmune markers, toxicology screening, or liver biopsy may be indicated to confirm the diagnosis and guide management decisions.

Diagnosis

Liver Function Tests (LFTs):

Liver function tests, including serum levels of transaminases (such as alanine aminotransferase [ALT] and aspartate aminotransferase [AST]), bilirubin, alkaline phosphatase, and albumin, are essential for assessing the degree of liver dysfunction and determining the severity of hepatic injury.

Electroencephalogram (EEG) for Encephalopathy:

An EEG may be performed to evaluate for the presence of hepatic encephalopathy, a common complication of fulminant hepatitis characterized by alterations in brain electrical activity. EEG findings can help confirm the diagnosis and guide treatment decisions.

Toxicology Screening:

Toxicology screening involves testing for the presence of toxic substances, drugs, or medications that may contribute to liver injury or exacerbate fulminant hepatitis. Identifying and eliminating hepatotoxic agents is crucial for preventing further liver damage and optimizing patient management.

Viral Markers and Autoantibodies:

Serological testing for viral markers, including hepatitis A, B, and C viruses, as well as autoantibodies associated with autoimmune hepatitis (such as anti-nuclear antibodies [ANA], anti-smooth muscle antibodies [ASMA], and anti-liver/kidney microsomal antibodies [LKM]), helps identify the underlying etiology of fulminant hepatitis and guide specific treatment strategies.
Additionally, testing for serum and urinary copper levels may be indicated to evaluate Wilson’s disease, a rare inherited disorder characterized by abnormal copper metabolism and hepatic copper accumulation.

Abdominal Ultrasound:

Abdominal ultrasound imaging is a non-invasive diagnostic tool used to evaluate liver morphology, assess for the presence of hepatic lesions or masses, and detect signs of portal hypertension, ascites, or biliary obstruction. Ultrasound findings may provide valuable information about the underlying pathology and guide further diagnostic and therapeutic interventions.

Imaging Studies:

In addition to abdominal ultrasound, other imaging modalities, such as computed tomography (CT) scans or magnetic resonance imaging (MRI), may be performed to further characterize liver anatomy, assess for complications such as hepatic abscesses or portal vein thrombosis, and guide treatment planning.

Liver biopsy (if indicated):

In certain cases, a liver biopsy may be warranted to obtain histopathological confirmation of the diagnosis, assess the degree of liver inflammation and fibrosis, and rule out other causes of liver injury. However, liver biopsy is not routinely performed in all cases of fulminant hepatitis and should be reserved for selected patients based on clinical judgment and individualized risk-benefit considerations.

Treatment

Potassium-Sparing Diuretics:

Administration of potassium-sparing diuretics, such as spironolactone (100mg orally per day), helps reduce edema while conserving potassium for essential cellular metabolism.

Management of Cerebral Edema:

Cerebral edema is managed by administering mannitol, an osmotic diuretic that helps reduce intracranial pressure and alleviate symptoms of hepatic encephalopathy.

Nutritional Support:

Vitamin supplementation, including vitamin A, vitamin B complex (1 tablet daily), vitamin C, and vitamin K, is provided to improve the integrity of mucous membranes in the gastrointestinal tract and enhance prothrombin levels for effective blood coagulation.

Antibiotic Therapy:

Antibiotics such as amoxicillin may be prescribed to treat suspected bacterial infections, particularly in cases of fulminant hepatitis associated with bacterial translocation and systemic inflammation.

Abdominal Paracentesis:

Abdominal paracentesis is performed to remove ascitic fluid in cases of significant ascites, relieving abdominal discomfort and respiratory compromise associated with fluid accumulation in the peritoneal cavity.

Gastrointestinal Protection:

Anti-acid medications and H2-receptor antagonists, such as magnesium trisilicate, are administered to reduce the risk of gastrointestinal bleeding from stress ulcers, a common complication in critically ill patients with fulminant hepatitis.

Liver Transplantation:

Liver transplantation is considered the treatment of choice for eligible patients with fulminant hepatitis, offering the best chance for long-term survival and resolution of liver failure.

Steroid Therapy:

Steroids, such as prednisolone, may be used as adjunctive therapy to reduce inflammation and modulate the immune response in selected cases of fulminant hepatitis, particularly those with autoimmune etiologies.

Intravenous 10% Dextrose:

Intravenous administration of 10% dextrose solution is provided to maintain adequate glucose levels and prevent hypoglycemia, which can exacerbate hepatic encephalopathy and metabolic derangements in patients with fulminant hepatitis.
