          Abstract

          As proteínas de choque térmico (heat-shock proteins - Hsp) são estruturas ubíquas e conservadas na evolução das espécies. São sintetizadas por uma grande variedade de seres vivos. Enquanto algumas são constitutivas, outras são marcadores de estresse celular. Há considerável homologia molecular entre Hsp bacterianas e humanas. Este mimetismo antigênico pode induzir a síntese de anticorpos cruzados a partir de infecções. Anticorpos contra várias Hsp são detectáveis em doenças do tecido conjuntivo (DTC) e doenças auto-imunes do ouvido interno. O significado patogênico destes achados é ainda discutível. A Hsp de 65 kilodaltons (kDa) é componente da placa aterosclerótica. Em anos recentes, anticorpos anti-Hsp de 60/65 kDa foram associados ao deflagramento do processo aterosclerótico. Nesta revisão, discutimos os achados acerca destes anticorpos tanto em doenças autoimunes como na aterosclerose coronária e cerebral.

          Translated abstract

          Heat-shock proteins (HSP) are ubiquitous and highly conserved structures, synthesized by a variety of species. While some HSP are constitutive, other are markers of cell activation. There is considerable molecular homology between bacterial and human HSP. This antigenic mimetism may generate the production of cross-reactive antibodies in patients with infections. Antibodies to several HSP are detectable in connective tissue disorders (CTD) and autoimmune inner ear diseases. The pathogenic significance of this finding is still controversial. The 65 kilodaltons (kDa) HSP is an atherosclerotic plaque component. In recent years, anti-60/65 kDa HSP antibodies have been associated to the development of the atherosclerotic process. In this review, we discuss the features concerning the presence of these antibodies in autoimmune diseases as well as in coronary and cerebral atherosclerosis.

              Steroid use in idiopathic sudden sensorineural hearing loss.

              Few studies have investigated the effect of steroids on idiopathic sudden hearing loss (ISHL). Recently, Wilson, et al., reported a double blind study demonstrating a statistically significant improvement of hearing using steroids is ISHL. This report, fashioned after the Wilson study, confirms his findings and analyzes the relationship of several factors to the probability of hearing recovery.
