title: Salivary and lacrimal secretions in patients on lithium therapy.
abstract: Salivary and lacrimal secretion rates and salivary composition were examined in 22 manic-depressive patients on lithium therapy and in 21 matched, healthy controls. Serum immunoglobulins (IgG and IgA) were measured in these patients. Their oral health was examined and found to be unimpaired. Significantly lowered tear secretion was detected in the patients, while their salivary secretion rates were normal. The salivary concentrations of NA, K and IgA were significantly elevated in whole saliva. In parotid saliva, the concentrations of K and IgA were elevated, while Na was in the normal range. A significant correlation between serum and salivary lithium concentrations was found, indicating the usefulness of salivary measurements for monitoring. Informed consent of the patients was obtained after the nature of the procedures had been fully explained.
