Recent studies postulated the association between bullous pemphigoid (BP) and
neurodegenerative disorders (ND). The autoantibodies to BP180 and/or BP230 may be
present not only in BP, but also in ND as neuronal isoforms of these proteins are
identified in the central nervous system. However, there are only scant data
about the precise pathogenetic mechanisms interlinking ND and BP as well as the
immunologic profile in these patients. The aim is to analyze the serological
immunopathological profiles (anti-BP180 IgG, anti-BP230 IgG) in BP patients with
and without ND in order to identify the specific autoantibody(ies) and
corresponding antigens responsible for ND development in BP patients. Altogether,
82 ethnic Poles with BP and their medical records were examined (62 BP-ND; 20
BP+ND). Levels of serum anti-BP180/BP230 IgG in BP patients were evaluated with
ELISAs. The statistical analyses involved Pearson chi-squared test, Mann-Whitney
U-test and ranking of autoantibodies. The prevalence of ND among BP patients was
24.4%. There were no statistically significant differences in autoantigens
profiles (anti-BP180/anti-BP230 IgG) between BP+ND and BP-ND groups. There was no
relationship between ND development and anti-BP180/anti-BP230 IgG level (p =
0.5933, p = 0.4701, respectively). The autoantibodies levels of BP+ND and BP-ND
patients show insignificant differences suggesting that also in ethnic Poles a
hypothetical pathogenetic association of BP and ND, but not only an aging-related
epidemiological one, appears to be independent of a particular BP antigen.
Nevertheless, it cannot be excluded that phenomena of epitopes spreading, immune
cross-reaction and conformational changes in BP180/BP230 may underlie BP
development in ND patients.
