Hepatitis E virus (HEV) is increasingly diagnosed in developed nations, unlike Hepatitis A virus (HAV). HEV infections may be underdiagnosed, often presenting asymptomatically, posing risks to vulnerable populations.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Hepatitis A virus (HAV) incidence is declining, while Hepatitis E virus (HEV) is rising globally, particularly in developed countries.
- Both viral hepatitis infections are linked to socio-economic factors and remain significant public health concerns worldwide.
- Viral hepatitis diagnosis and management require ongoing surveillance and understanding of transmission dynamics.
Purpose of the Study:
- To analyze the epidemiological characteristics of hospitalized viral hepatitis cases in Romania.
- To compare the incidence and clinical presentation of Hepatitis A virus (HAV) and Hepatitis E virus (HEV) infections.
- To highlight the potential underdiagnosis and public health implications of HEV infection.
Main Methods:
- Retrospective analysis of medical records from patients hospitalized with viral hepatitis.
- Inclusion of serologically confirmed cases of HAV and HEV infections between 2018 and 2019.
- Data collection on patient demographics, clinical presentation, and outcomes.
Main Results:
- A total of 269 HAV-infected patients were analyzed, with males (53.9%) and adolescents aged 8-15 years (53.6%) being the most affected.
- Severe HAV infections occurred in 2.24% of cases, with favorable outcomes under supportive treatment.
- Only three adult males were confirmed with HEV infection, suggesting potential underreporting or asymptomatic cases, despite a regional seroprevalence of 32.5%.
Conclusions:
- Hepatitis A virus (HAV) outbreaks continue in the region, predominantly affecting young males.
- Hepatitis E virus (HEV) infection appears underdiagnosed and underreported, possibly due to asymptomatic or subclinical presentations.
- HEV poses significant risks to vulnerable groups, including pregnant women and immunocompromised individuals, necessitating further investigation and public health strategies.

Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
