ABSTRACT
Revision is made to 121 Chilean patients with progressive adult spastic paraparesis (PSPs) associated to HTLV-I. Epidemiologic, clinical, diagnosis and associated illnesses aspects are analyzed as well as the pathogenesis. The follow-up of patients during several years allowed defining the evolutional profile, establishing the causes of death and studying the virus' behavior. Pathogenesis hypothesis arose from the neuropathological search to define the mechanisms of damage supported on immunohystochemical studies. It was confirmed that the CNS illness is a degenerative process linked to a central axonopathy which expresses flaws in the axoplasmic transport, particularly affecting the corticospinal tracts, although there is a more extended myeloencephalic involvement. Furthermore, the virus is capable of producing a multisystemic illness that may simultaneously involve the nervous system; the hematological system; the exocrine glands; the hepatic, lung, muscular and bone parenchymas.
RESUMEN
Se revisan las paraparesias espásticas progresivas del adulto (PEPAs) producidas por el HTLV-I, en 121 pacientes chilenos. Se analizan los aspectos epidemiológicos, clínicos, diagnósticos, las enfermedades asociadas, y la patogenia. El seguimiento de los pacientes durante varios años permitió definir el perfil evolutivo, establecer las causas de muerte y estudiar el comportamiento del virus. De los casos con anatomía patológica surgieron hipótesis, que han permitido definir mecanismos de daño, sustentados en estudios inmunohistoquímicos. Se pudo confirmar que la enfermedad del SNC es un proceso degenerativo, vinculado a una axonopatía central que expresa fallas del transporte axoplásmico, que afecta particularmente la vía corticoespinal, aunque existe un compromiso más extenso mielo-encefálico. Además, el virus es capaz de producir una enfermedad multisistémica, que puede comprometer simultáneamente el sistema nervioso, el sistema hematológico, las glándulas exocrinas, el parénquima hepático, pulmonar, muscular y óseo.
