Severe thrombocytopenia in Epstein-Barr virus-induced mononucleosis
Abstract:
Severe thrombocytopenia is a rare complication of Epstein-Barr virus-induced infectious mononucleosis. We evaluated the clinical and laboratory data from seven patients seen between 1976 and 1985 whose lowest platelet counts varied from 3 to 25 x 10(9) per liter. Five of the seven patients were initially thought to have either acute leukemia or idiopathic thrombocytopenic purpura; eventually, however, primary Epstein-Barr virus infections were confirmed in all patients. Two of six patients tested had antiplatelet antibodies during the acute phase of their illnesses. Eight additional patients with acute disease who had only mild thrombocytopenia (94 to 144 x 10(9) per liter) were also tested for platelet antibodies with negative results. Steroid therapy was administered to three patients and platelet transfusions to one. All seven patients recovered with no serious hemorrhagic sequelae.
Insights
Severe thrombocytopenia, a rare Epstein-Barr virus complication, can mimic leukemia. This study confirms EBV as the cause in patients with low platelets, who recovered fully with treatment.
Area of Science:
- Hematology
- Virology
- Immunology
Background:
- Epstein-Barr virus (EBV) infection, commonly known as infectious mononucleosis, can present with hematological complications.
- Severe thrombocytopenia (low platelet count) is an uncommon but significant manifestation of EBV infection.
Purpose of the Study:
- To evaluate clinical and laboratory findings in patients with severe thrombocytopenia associated with Epstein-Barr virus.
- To investigate the presence of antiplatelet antibodies in patients with EBV-induced thrombocytopenia.
Main Methods:
- Retrospective review of clinical and laboratory data from seven patients with severe thrombocytopenia (platelet counts 3-25 x 10(9)/L) due to Epstein-Barr virus.
- Serological testing for Epstein-Barr virus infection confirmation.
- Assay for antiplatelet antibodies in affected patients.
Main Results:
- All seven patients with severe thrombocytopenia were confirmed to have primary Epstein-Barr virus infections.
- Five patients were initially misdiagnosed with acute leukemia or idiopathic thrombocytopenic purpura.
- Two of six patients tested positive for antiplatelet antibodies during the acute phase; eight patients with mild thrombocytopenia tested negative.
Conclusions:
- Epstein-Barr virus infection can cause severe thrombocytopenia, often requiring differentiation from other hematological disorders.
- The presence of antiplatelet antibodies may be associated with EBV-induced severe thrombocytopenia.
- Patients with EBV-associated severe thrombocytopenia demonstrated good recovery with appropriate medical management, including steroids and platelet transfusions.
