Histopathological results of biopsies were collected and clinical files of patients were assessed so as to determine which cases met with the SS diagnosis criteria proposed by the European and American Consensus Group in 2002. Thus, primary diagnosis of Sjögren's syndrome was established based on positive ocular and oral symptoms, with the help of Schirmer's test.
Se recopilaron los resultados histopatológicos de las biopsias realizadas y se evaluaron los expedientes clínicos de los pacientes para determinar aquellos casos que cumplían con los criterios de diagnóstico de SS propuestos por el Grupo de Consenso Americano y Europeo en el 2002.
