AB The aetiology of autoimmune diseases remains unknown. The relationship
between virus, and more recently retrovirus, has been suggested with
this group of diseases. Immunoblotting is a useful method for
determining the presence of proteins coded by different retrovirus
genes. Since the prevalence of these types of proteins in patients with
primary Sjogren's syndrome (SS), systemic lupus erythematosus (SLE),
rheumatoid arthritis (RA) and autoimmune thyroid diseases has not been
fully established, the aim of this work was to determine the prevalence
of antibodies to immunodeficiency human virus type 1 (HIV-1) proteins in
these diseases and their possible relationship with the presence of
anti-nuclear, anti-DNA, anti-SSA (Ro) and anti-SSB (La) autoantibodies.
Antibodies to human immunodeficiency virus (HIV-1) were studied in a
group of 341 patients with autoimmune diseases (77 SS, 98 SLE, 75 RA, 91
autoimmune thyroid diseases) and 126 blood donors as a control group. A
Western blot was used to detect antibodies to HIV-1, and a double
polymerase chain reaction (PCR) using nested primers in the gag and pol
gene of HIV-1. Antinuclear antibodies, anti-DNA, anti-SSA (Ro) and
anti-SSB (La) were determined by enzyme-linked immunosorbent assays. At
least one band was shown on immunoblotting in 26% of patients with
autoimmune diseases and 35% of controls. The presence of antibodies to
p55 or p68 proteins in patients with SS or SLE proved to be the only
statistically significant difference between the other autoimmune
diseases studied and the control group. These antibodies were not
associated with autoantibodies ANA, DNA, SSA (Ro) or SSB (La).(ABSTRACT
