Nutritional correlates of atrophic glossitis: possible role of vitamin E in papillary atrophy

Atrophy of the filiform papillae of the tongue is a sign of malnutrition. However, papillary atrophy has not been correlated with laboratory indices of nutritional status. We studied photographs of tongues from 30 elderly subjects and determined the percentage of normal papillary development (%NPD) relative to a reference photograph. We also determined 16 nutritional blood levels and used stepwise multiple linear regression to examine their relationship to %NPD. We found that %NPD correlated significantly (p < 0.0031) with levels of vitamin E and prealbumin, but not with 14 other laboratory indices. Subjects with overt atrophic glossitis (%NPD < 50%) tended to have multiple nutritional deficiencies. The high correlation of plasma vitamin E levels with %NPD may be related to its role as an antioxidant and in the maintenance of cellular membrane integrity.
