CONCLUSION: Keratin-specific immune responses in tonsils may be associated with the pathogenesis of pustulosis palmaris et plantaris (PPP). Evaluation of keratin-specific immune responses in tonsils might be useful to predict the effectiveness of tonsillectomy for patients with PPP.
OBJECTIVES: The aim of the present study was to clarify the role of keratin-specific immune responses in the pathogenesis of PPP in tonsils. It has been reported that anti-keratin antibodies in serum were higher in patients with PPP and decreased after tonsillectomy, indicating that anti-keratin antibodies might be generated in tonsils.
METHODS: In order to demonstrate the presence of keratin-specific immune responses in tonsils, the numbers of keratin-specific antibody-forming cells (AFCs) in tonsillar and peripheral blood lymphocytes were examined by enzyme-linked immunospot assay. The prognosis of PPP was compared after tonsillectomy.
RESULTS: The numbers of keratin-specific IgM and IgG AFCs in tonsils and of IgG AFCs in peripheral blood were significantly increased in patients with PPP. The numbers of keratin-specific IgG AFCs in peripheral blood correlated positively with tonsil and serum IgG antibodies specific to keratin. Our data show that a good prognosis in patients with PPP depended on the numbers of keratin-specific IgG and IgM AFCs in peripheral blood and the levels of keratin-specific IgG antibodies in serum being significantly decreased 6 months after tonsillectomy.
