AIM:. Sjögren’s syndrome (SS) represents a challenging illness to diagnose properly and, because of the serious complications such as lymphoma, it is important to reach a correct diagnosis in early stages. Aim of this retrospective study was to evaluate the correlation between histopathologic result of minor salivary gland biopsy and clinical and serologic parameters for the diagnosis of SS.
METHODS: We evaluated 360 biopsies, taken from the lower lip, of 360 patients (18 males) on suspicion that they were suffering from SS. The Chisolm and Mason classification was used to state the diagnosis of SS. For each patient, the medical history and the symptoms were evaluated, and diagnostic tests were performed. The revised rules of the American-European Consensus Group Criteria were used to diagnose primary and secondary SS. For the statistical analysis we used the c2 test; a difference of P<0.05 was considered significant.
RESULTS: Considering the statistical correlation between a focal score ≥1 and the serological data, it was noted that a positive score was significantly correlated to all serological parameters examined (P<0.0001). A significant correlation was also found between a positive biopsy score and Schirmer’s test and Rose Bengal test (P<0.0001). However, with regard to the clinical data, a significant correlation was found only for two parameters: xerostomia (P<0.0001) and parotid swelling (P<0,05).
CONCLUSION: Minor salivary gland biopsies are of great diagnostic value in detecting SS. However, for the diagnosis of SS both clinical and serologic parameters should be considered. The data obtained from the present survey reveal that the serologic markers are more predictive than clinical parameters for a positive biopsy score.
