COMPARATIVE ANALYSIS OF SEROLOGICAL MARKERS OF HERPES VIRUSES AND QUANTITATIVE IMMUNOGLOBULINOPATHIES IN PRIMARY PATIENTS WITH ANGIOIMMUNOBLASTIC T-CELL LYMPHOMA

Abstract

Introduction. Angioimmunoblastic T-cell lymphoma (AITL) is associated with the Epstein-Barr virus (EBV) in most cases. It is believed polyclonal hypergammaglobulinaemia observed in 53-80% of AITL patients has anti-herpes viral antibodies as its substrate. Aim. The aim of the study was to compare serological markers of herpes viruses and quantitative immunoglobulinopathies of classes M and G in primary patients with AITL. Materials and methods. 26 primary patients with newly diagnosed AITL treated at the National Research Center for Hematology from 2002 to 2017 were enrolled in the study. The male/female ratio was 16/10; median age was 62 (29-81) years. The levels of total immunoglobulins of classes M and G, serological markers of EBV, cytomegalovirus (CMV) and herpes simplex virus type 1 and type 2 (HSV 1, 2) were assessed in all patients. Results. Significant relationship was found between the presence of virus-specific IgM (IgM HSV 1, 2, IgM CMV, IgM VCA EBV) and an elevated level of total immunoglobulins of class M (p
