HEV in Patients With Acute Non-A, Non-B, Non-C Hepatitis in Al-Rajhy University Hospital for Liver

July 22, 2018 updated by: Mahmoud Abdel Rahman

Hepatitis E Virus Infection Among Patients With Acute Non-A, Non-B, Non-C Hepatitis in Al-Rajhy University Hospital for Liver

Hepatitis E is the fifth known human viral hepatitis and is probably the most common cause of acute viral hepatitis in the world. The incidence of acute hepatitis E is estimated at 3 million human cases per year worldwide, with around 70,000 deaths. Most cases occur in endemic countries, but the number of cases in low-endemic areas has increased. HEV seroprevalence is high in developing countries, such as India and Southeast Asia, ranging from 27-80%. Acute disease mortality is 1-4%, with risk being higher in pregnant women and immunodeficient patients.

The four more prevalent genotypes are allocated into two groups. Epidemic hepatitis E includes genotypes 1 and 2, which are considered human viruses and have caused the epidemics of hepatitis. These forms are transmitted mainly by contaminated water and the fecal-oral route. endemic hepatitis E includes genotypes 3 and 4, which are considered swine viruses (common in domestic and wild pigs), capable of infecting humans as an accidental host and therefore considered zoonotics.

The course and clinical presentation of hepatitis E is highly variable. The detailed mechanisms that lead to the different clinical outcomes in hepatitis E are only partially understood. It is known that both viral factors (genotype and dose of inoculum) and host factors (presence of previous liver disease, pregnancy and distinct genetic polymorphisms) determine the course of infection. In most cases, hepatitis E causes self-limited illness, lasting from a few days to weeks, with an average of 4-6 weeks. However, in developed countries it can cause chronic disease with rapid progression to cirrhosis, especially in patients who are transplanted, have hematological malignancies requiring chemotherapy, or have infection with HIV.

Hepatitis E is an underdiagnosed disease, partly due to the use of serological tests with low sensitivity. Diagnosis can be made indirectly by detecting antibodies against HEV in the serum, or directly by detecting the genome of the virus in blood or other body fluids. The tests for anti-hepatitis E antibody screening are commercially available, but none of them has been approved by the Food and Drug Administration (FDA). Unfortunately, the sensitivity and specificity of these tests vary greatly and this could explain the discrepancies in rates of anti-hepatitis E antibodies published for the various populations studied. The tests for viral RNA in serum and feces are confirmatory, but still experimental.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
HEV incidence estimation among acute hepatitis patients
Time Frame: 1-2 years
in our university hospital HEV is underestimated due to the lack of laboratory investigation of it . so, by this study we aim to estimate the number of affected cases with HEV infection among symptomatic patients with acute hepatitis.
1-2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Detection of Hepatitis E viral nucleic acid in stool and serum
Time Frame: 1-2 years
Detection of Hepatitis E viral nucleic acid in stool and serum of acute non- A, B or C hepatitis patients and compare between the viral load in both samples. and according the results we can recommend the preferred sample type to be used later for detection of the virus .
1-2 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
medical recommendation
Time Frame: 1-2 years
if our study found high incidence of HEV among patients with acute hepatitis , we can then recommend (with evidence) adding Acute HEV infection testing modalities as a routine investigation to AL-Rajhy hospital protocols in managing Acute hepatitis patients.
1-2 years
