Comparison of reactivity and epitope recognition between sera from American and Italian patients with oral pemphigoid.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mucous membrane pemphigoid (MMP) (also known as cicatricial pemphigoid) is a rare autoimmune mucocutaneous blistering disease that affects mucous membranes derived from stratified squamous epithelium and the skin. A subset of MMP affects only the oral cavity and is referred to as the oral pemphigoid (OP). MMP and OP are characterized by subepithelial vesicles on histology and in vivo deposition of immunoglobulins and complement at the basement membrane zone (BMZ) on immunopathology. Previous studies have shown that sera of patients with MMP bind to human integrin beta4, while sera of patients with oral pemphigoid bind to the integrin alpha6 component of the heterodimer. The prognosis in MMP is grave but excellent in OP. In this study we compare the binding of sera from patients with OP from Boston, MA, USA to Naples, Italy, and attempt to identify an epitope to which the anti-integrin alpha6 human autoantibody binds. Our results indicate that the sera from Boston and Naples are identical in their reactivity. They recognize a fragment I (AA 23-462) and its subfragment IB (AA 217-462) only, in the human integrin alpha6 molecule. Blocking studies, immunoprecipitation and immunoabsorbtion studies confirm the presence of this single 245 AA region. Antibodies to subfragment IB cause BMZ separation in organ culture using normal human oral mucosa as substrate. This preliminary study indicates that patients on both continents may have similar reactivity and suggests that an intercontinental study group could be established to advance our understanding of the pathogenesis of OP and the biology of anti-alpha6 integrin autoantibodies.
