To develop new classification criteria for childhood Sjögren's syndrome (SS).
Adult classification criteria for SS have not been validated in children and currently proposed pediatric criteria lack diagnostic sensitivity.
Retrospective review of medical records of 41 patients (pts) was performed at Children's Hospital of Philadelphia and the Penn Sjögren Center to identify cases of suspected pediatric SS. Diagnosis by physician global assessment required 1) symptom onset at age <20 yrs, 2) consensus agreement on diagnosis by pediatric and adult rheumatologists, 3) abnormal serologies and/or lip biopsy. Pts with overlapping autoimmune disease were not excluded. Clinical presentation, serologies, objective tests for sicca and histopathology were reviewed. All available salivary gland biopsies were blindly reviewed by oral pathologists to calculate a focus score (FS) and compared to biopsy findings from non-SS pts. Pts were also classified as childhood SS (score:3 or more) or non SS (score 2 or less) using a novel scoring system (maximum = 8) based on a modification of American-European Consensus Group (AECG) criteria (Vitali et al, 2002).
Following global assessment and long term follow-up of the pediatric cohort (41 pts), 35 pts had confirmed childhood SS, 3 pts had suspected but unconfirmed SS, and 3 pts were diagnosed as HIV, sarcoidosis, or IPEX syndrome. Using the novel scoring system, all 35 pts with definite childhood SS were classified as SS and all 3 pts with other final diagnosis were classified as non SS.
An expert oral pathologist blindly calculated FS in 21 pts. Among 17 pts with definite childhood SS, FS and Classification Score were positively correlated (R=0.67 p<0.005) and 8 pts had FS less than 1.
Inclusion of the presence of ANAs and any focal lymphocytic sialadenitis (both more clinically significant in children than adults) in classification criteria for childhood SS can be used to maximize diagnostic sensitivity in order to facilitate earlier treatment and prevent long-term complications.
