Incidence of antiphospholipid antibodies in new patients with non-Hodgkin lymphoma

Abstract

Non-Hodgkin’s lymphoma (NHL) presents a group of histologically and biologically inhomogeneous B and T cell neoplasms of lymphoid tissue with a completely unidentified etiology. Antiphospholipid antibodies (aPL) are antibodies produced as a result of misinterpretation of platelet membrane phospholipids. It is well known that antiphospholipid antibodies are general risk factors that induce the disorder of the physiological process of hemostasis. Respectively, it is interesting to appreciate the incidence of antiphospholipid antibodies in new non-Hodgkin lymphomas patients depending on age, sex, type of non-Hodgkin’s lymphoma, the peculiarities of the onset of the disease, the degree of disease spread. According to the results of our study, we found a 14.8% incidence of aPL in primary patients with non-Hodgkin’s lymphoma, more frequently in men and people older than 50 years. The positivity of aPL antibodies depended on the immunohistochemical type of malignant lymphoma, the degree of dissemination of the tumor process and independent of the location of the tumor focus (nodal or extranodal) of NHL. The incidence of aPL antibody types was uneven with the obvious predominance of lupus anticoagulant. Th is study allowed the evaluation of the incidence of antiphospholipid antibodies in primary patients with non-Hodgkin’s lymphoma.
