Resumen

ARROYAVE-OSPINA, Johanna C.; CAICEDO, María Fernanda; NAVAS, María Cristina  y  CORTES-MANCERA, Fabián M.. Human Pegivirus: Pathogenic potential and non-Hodgkin lymphoma development risk. Rev. chil. infectol. [online]. 2018, vol.35, n.2, pp.164-175. ISSN 0716-1018.  http://dx.doi.org/10.4067/s0716-10182018000200164.

The human pegivirus (HPgV), classified in the Flaviviridae family - Pegivirus genus, is an RNA virus identified in 1995. HPgV is a lymphotrophic virus, with replication sites in bone marrow and lymphoid tissue, as well as in peripheral blood mononuclear cells (PBMCs). Transmission is through sexual and parenteral routes, and recent estimations suggest nearly 750 million people are infected with HPgV worldwide. Almost 25% of infected individuals can develop persistent infection. Until now, HPgV has been considered a non-pathogenic virus; however, epidemiological studies suggest a potential role in lymphoproliferative diseases, particularly in the development of non-Hodgkin lymphoma (NHL). The evidence of this is controversial and the role of HPgV in lymphomagenesis has not yet been demonstrated. Several studies report a high prevalence of HPgV infection in patients with NHL compared to controls and patients with other hematological diseases. Therefore, analytic studies show that HPgV could be related to an increased risk of NHL development. Conversely, other studies indicate no association between HPgV and NHL, so the role of HPgV in lymphomagenesis is not clear. This review summarizes the main findings related to HPgV's pathogenic potential and association with NHL.
