[Morphological Characteristics of Bone Marrow Cells in Patients with EB Virus Infection]

Review and analyze the characteristics of bone marrow cell morphology in patients with Epstein-Barr virus (EBV) infection, and explore the diagnostic value of bone marrow cell morphology for the early identification of EBV infection.

A total of 33 patients with EBV-DNA positive detection in the First Affiliated Hospital of Guangxi Medical University from January 2018 to May 2021 were collected as the research objects. Bone marrow cell morphology and peripheral blood cell analysis were performed, and the significance in disease diagnosis was analyzed by statistical methods.

The sampling satisfaction of 33 patients with EBV infection was 100%. In the clinical diagnosis of all cases, 7 cases were IM, 17 cases were EBV-HLH, 3 cases were lymphoma, 2 cases were EBV-associated lymphoid hyperplasia, and 4 cases were not diagnosed. Among them, 31 patients had active bone marrow hyperplasia or above, 26 patients had active granulocytic hyperplasia or above, 21 patients had active erythroid hyperplasia or above, and 17 cases of megakaryocyte production platelet function decreased. The abnormal components of bone marrow mainly indude atypical lymphocyte cells (33 cases), hemophagocytic cells (22 cases), abnormal histiocyte (10 cases).

According to the proliferation of granulocytes, erythrocytes and megakaryocytes in the bone marrow, and the emergence of abnormal components such as atypical lymphocytes, hemophagocyte, abnormal histiocyte. Bone marrow cell morphological examination can indicate the possibility of EBV infection, which is certain diagnostic value for early identification of EBV infection.
