Hepatitis E: A Viral Liver Disease

Hepatitis E is a viral infection that causes liver inflammation and damage, leading to symptoms such as fever, malaise, anorexia, nausea, and abdominal pain [2]. It is a common disease in many parts of the world where sanitation is poor [1].

Transmission and Symptoms

The hepatitis E virus (HEV) is transmitted through the feco-oral route, meaning it can be spread through contaminated food and water or by coming into contact with an infected person's stool [7]. The symptoms of hepatitis E are similar to those of hepatitis A and include fatigue, muscle pain, loss of appetite, nausea and vomiting, fever, cough, abdominal pain and diarrhea, and dark urine and light-colored stools [6].

Global Prevalence

Hepatitis E is an important cause of acute hepatitis worldwide, with a significant burden in countries with inadequate sanitation and hygiene practices [8]. The disease is more common in regions where access to clean water and proper waste disposal is limited.

Key Points:

• Hepatitis E is a viral liver disease caused by the hepatitis E virus (HEV)
• Symptoms include fever, malaise, anorexia, nausea, abdominal pain, fatigue, muscle pain, and dark urine
• The disease is transmitted through the feco-oral route
• Hepatitis E is more common in countries with inadequate sanitation and hygiene practices

Hepatitis E is a viral infection that causes inflammation in your liver, leading to various symptoms. The signs and symptoms of hepatitis E can vary from person to person but often include:

• Fever: A mild to moderate fever is common in people with hepatitis E [2].
• Vomiting: Nausea and vomiting are frequent complaints among those infected with the virus [4].
• Abdominal pain: Pain or discomfort in the upper part of the abdomen, particularly on the right side where the liver is located, is a symptom experienced by many [5].
• Dark-colored urine: The urine may appear darker than usual due to the liver's inability to filter waste properly [6].
• Jaundice: A yellowing of the skin and eyes can occur as the liver becomes inflamed [4].
• Fatigue: Feeling extremely tired or exhausted is a common symptom, often accompanied by muscle pain (myalgia) [7].
• Loss of appetite: People with hepatitis E may experience a decrease in hunger due to nausea and vomiting [5].
• Darkening of stool: The stool may appear lighter than usual due to the liver's reduced ability to filter waste [5].

It is essential to note that some people may not exhibit any symptoms at all, while others may experience mild flu-like symptoms. If you suspect you have hepatitis E or are experiencing any of these symptoms, it is crucial to consult a healthcare professional for proper diagnosis and treatment.

Diagnostic Tests for Hepatitis E

Hepatitis E can be diagnosed through various laboratory tests, which are essential for confirming the presence of the virus in the body.

• Serological assays: These tests detect the presence of antibodies against the Hepatitis E virus (HEV) in the blood. The results of these tests are often negative in the early stages of infection [1].
• IgM and IgG anti-HEV antibody detection: This test is used to diagnose acute hepatitis E by detecting IgM antibodies, which indicate a recent infection. IgG antibodies, on the other hand, indicate a past or chronic infection [3][4].
• HEV RNA detection: Detecting HEV RNA in serum or stool specimens further confirms the serologic diagnosis and is often used as an additional test to confirm the presence of the virus [3][4].
• Blood tests and stool tests: These are commonly used tests by doctors to diagnose hepatitis E. The blood test detects antibodies against the virus, while the stool test detects the virus itself [5].

Accurate Diagnosis

Accurate diagnosis relies on HEV-specific diagnostic testing, including tests for anti-HEV antibodies, viral RNA, and viral antigens [8]. It is essential to note that laboratory tests are necessary to confirm the presence of hepatitis E, as symptoms alone may not be sufficient to diagnose the condition.

Treatment Options for Hepatitis E

Hepatitis E, a liver infection caused by the hepatitis E virus (HEV), can be treated with various medications to manage symptoms and support recovery.

• Pegylated Interferon-Alpha: This antiviral medication has been used successfully in treating chronic hepatitis E, especially in patients who have not responded well to ribavirin treatment [1]. However, it is associated with major side effects, including cholestasis [1].
• Ribavirin: An antiviral drug that can help the body get rid of the virus. Treatment typically lasts for 3 months and may be accompanied by significant side effects [7].
• Reduction of Immunosuppressive Medication: For patients with chronic HEV infection, reducing or discontinuing immunosuppressive medication can also be an effective treatment option [4].

Important Considerations

• No Specific Treatment: There is no specific treatment for hepatitis E. Most people recover from the infection with rest and symptom management [3].
• Avoid Alcohol: It's essential to avoid alcohol consumption as it can increase liver damage [6].
• Medication Interactions: Patients should consult their doctor before taking any medication that may harm the liver, such as acetaminophen [8].

The differential diagnosis of hepatitis E involves identifying other conditions that can present with similar symptoms, making it essential to rule out these possibilities before confirming a diagnosis of HEV infection.

According to various sources [4][8][9], the differential diagnosis for acute hepatitis E includes:

• Hepatitis A: Both hepatitis A and E can cause similar symptoms such as fever, nausea, vomiting, jaundice, hepatomegaly, icteric sclera, elevated ALT levels, and liver failure in rare cases [4][8].
• Drug-induced liver injury (DILI): DILI is an essential differential diagnosis for acute hepatitis E, particularly in patients with a history of medication use [9].
• Other viral hepatitis: Other forms of viral hepatitis, such as hepatitis B and C, can also present with similar symptoms and should be considered in the differential diagnosis.

To confirm a diagnosis of HEV infection, healthcare providers typically rely on laboratory tests, including:

• Detection of IgM antibodies to HEV
• Presence of HEV RNA in serum or stool samples

These diagnostic methods help differentiate hepatitis E from other conditions that may present with similar symptoms.
