Diet and pemphigus. In pursuit of exogenous factors in pemphigus and fogo selvagem.
    Archives of dermatology, 1998, Volume: 134, Issue:11

    Individuals with a genetic predisposition to pemphigus will develop the disease only when one or more additional factors are present. The nature of these factors is as yet unknown, but our starting point was that certain drugs (penicillamine, captopril, and rifampicin) are recognized as such factors. Since some nutrients have chemical compositions similar to these known causative drugs, these nutrients may act similarly and, therefore, nutritional factors should also be suspected. As when drugs are involved, elimination of the inciting ingredients may be crucial for management of the disease. This article discusses the possible role of nutritional ingredients in the disease process of pemphigus, including fruit, leaves, roots, seeds, and even water. Possible causative candidates are thiol, thiocyanate, phenols, and tannins.

A glass of red wine to keep vascular disease at bay, but what about pemphigus vulgaris?
    Expert review of clinical immunology, 2011, Volume: 7, Issue:2

    Pemphigus vulgaris is a rare autoimmune blistering disease, involving the skin and mucous epithelia, which is characterized by flaccid blisters and erosions. It is caused by the presence of autoantibodies directed against desmoglein, a glycoprotein that plays a critical role in cell-cell attachment. Upon a predisposing genetic background, different agents have been shown to act as triggers for the pathogenesis of pemphigus. The most evident association is with drug intake, while the role of diet is often underestimated. The aim of this article is to review the possible role of tannins, a group of phenolic metabolites that are widely distributed in almost all plant foods and beverages, particularly red wine, as a trigger for pemphigus vulgaris.

In vitro tannin acantholysis.
    International journal of dermatology, 2000, Volume: 39, Issue:10

    Exogenous factors, such as certain drugs, may be involved in the induction of pemphigus. Other offenders sharing a similar chemical composition to these drugs may also play a role. Tannins with their considerable biologic activity were suggested as possible factors. To substantiate the role of tannins in the pathomechanism of pemphigus, the present study examined the acantholytic potential of tannins in vitro.. Normal human breast skin from patients without any bullous disease was cultured for 3 days in the presence of tannic acid at concentrations of 0.02, 0.05, 0.1, 0.25, 0.5, 1.0, and 2.0 mM. The effect of the tannic acid was microscopically examined in a blind fashion by three independent investigators.. In addition to the cytotoxic effect, tannic acid caused marked acantholytic changes, with a clear suprabasal cleavage and intraepidermal acantholytic cells. The acantholytic changes were the most constant and specific effects. They were constantly observed at 1.0 and 2.0 mM, whereas lower concentrations showed changes only in some of the explants. The concentrations needed to exert this effect were notably low. There was a remarkable variability among the subjects who had provided the explants.. The results suggest a possible role of tannin in the disease process of pemphigus. The tannin acantholytic potential was much greater than the potential of known acantholytic drugs, such as penicillamine and captopril. The interindividual variability in susceptibility to acantholysis may explain the variability in the individual potential for developing pemphigus.
