The predictive value of elevated labial saliva sodium concentration: its relation to labial gland pathology in bone marrow transplant recipients.

Journal Article (Journal Article)

Labial minor gland salivary flow rate and sodium concentration were analyzed in relation to 1) histologic findings in labial biopsy specimens and 2) the occurrence of chronic graft-versus-host disease (GVHD) in patients who received bone marrow transplants. Biopsy specimens and samples were obtained from 61 recipients of marrow transplants (including three twins) 51 to 1,260 days post transplantation. Labial saliva sodium concentrations were elevated in some patients, and these increases were associated with inflammation and destruction of minor salivary gland acini and ducts by chronic GVHD or other factors. The predictive value of the salivary sodium changes in evaluating labial salivary gland pathologic changes was 91 per cent, and the sensitivity was 74 per cent. Thus, if a transplant recipient is found to have an elevated labial saliva sodium level, then the probability that he has pathologic labial gland changes is 91 per cent. When analyses were restricted to include only patients who received no irradiation during transplantation, then elevated labial saliva sodium concentration was significantly associated with the occurrence of chronic GVHD. The sensitivity of this relationship was 42 per cent, but the predictive value was 100 per cent. Thus, if a nonirradiated transplant recipient is found to have an elevated labial saliva sodium concentration, then it is virtually certain that he has chronic GVHD. We found no significant changes in labial saliva flow rates in these bone marrow transplant recipients.
