From the Guidelines
Epstein-Barr virus (EBV) infection in the inpatient setting is a significant concern due to its potential to cause severe complications, particularly in immunocompromised patients, and requires prompt diagnosis and management to prevent morbidity and mortality. The clinical significance of EBV in the inpatient setting is multifaceted, involving various manifestations such as infectious mononucleosis, chronic active EBV infection, and post-transplant lymphoproliferative disorders. Management of EBV infections includes supportive care, monitoring for complications, and targeted therapy in certain cases.
Diagnosis and Management
Diagnosis of EBV infection typically involves serologic tests, such as heterophile antibody tests (Monospot) or EBV-specific serology, and may require quantitative viral load measurement and imaging with positron emission tomography in cases of suspected post-transplant lymphoproliferative disorders 1. The key to managing EBV infections lies in early recognition of severe cases and prompt intervention with therapies such as rituximab, reduction of immunosuppression, and EBV-specific cytotoxic T-cell therapy.
Complications and Prevention
Patients with EBV infection should be monitored for rare but serious complications including splenic rupture, airway obstruction, and neurological complications. Prevention of these complications involves restricting physical activity for 3-4 weeks in cases of significant splenomegaly and avoiding alcohol for at least 6 weeks due to potential liver involvement. Additionally, prophylaxis and preemptive therapy are crucial in preventing post-transplant lymphoproliferative disorders in patients undergoing hematopoietic stem cell transplantation 1.
Evidence-Based Recommendations
The most recent and highest quality study on the management of EBV infections and post-transplant lymphoproliferative disorders recommends a multifaceted approach including diagnosis, prevention, prophylaxis, and therapy 1. This approach emphasizes the importance of evidence-based recommendations in improving outcomes for patients with EBV infections, particularly in the inpatient setting.

From the Research
Clinical Significance of Epstein-Barr Virus (EBV) in the Inpatient Setting
The clinical significance of EBV in the inpatient setting is multifaceted, involving various complications and diseases associated with the virus. Some key aspects include:
- Chronic active EBV (CAEBV) can cause severe complications, such as acute hepatitis and ascites, as seen in a case study where an 81-year-old woman presented with these symptoms and was treated with acyclovir 2.
- EBV infection is associated with several B-cell malignancies, including Burkitt lymphoma, Hodgkin lymphoma, and post-transplant lymphoproliferative disease 3.
- CAEBV is characterized by systemic inflammation and clonal proliferation of EBV-infected T or NK cells, and diagnosis requires confirmation of a high copy number of EBV genome and EBV-infected T or NK cells 4.
- EBV reactivation can occur under conditions of psychological stress, weakening of cellular immunity, and in patients with certain cancers, autoimmune diseases, and chronic fatigue syndrome/myalgic encephalitis, and is an important mechanism in the pathogenesis of many diseases 5.
- EBV infection is also associated with lymphoproliferative diseases (EBV-LPD) in patients with primary or secondary immunodeficiencies, and the incidence of EBV-LPD is increasing due to advancements in transplant medicine and improvements in supportive care 6.
Diagnosis and Treatment of EBV-Related Diseases
Diagnosis and treatment of EBV-related diseases are crucial in the inpatient setting. Some key points include:
- Diagnosis of CAEBV requires confirmation of a high copy number of EBV genome and EBV-infected T or NK cells, with an EBV DNA load ≥ 10,000 IU/mL in whole blood proposed as the diagnostic cutoff value 4.
- A standard treatment approach for CAEBV has not been established, but hematopoietic stem cell transplantation (HSCT) is considered the only curative treatment, and chemotherapy can be administered to control disease activity before HSCT 4.
- Antiviral drugs have proven to be effective inhibitors of EBV replication, but have resulted in limited success clinically, and none have been approved for treatment of EBV infections 3.
- Acyclovir has been used as a potential new treatment option for severe CAEBV, as seen in the case study of the 81-year-old woman who made a complete recovery with no deficits 2.
