Both primary and secondary forms of SS occur, but their phenotypes are not well defined. No less than 10 sets of diagnostic/classification criteria for SS have been applied since 1965 (1–11), but none have been universally adopted or accepted by the American College of Rheumatology. These criteria have often identified patients with similar clinical features, but not necessarily with a common disease process. There is scant longitudinal data on SS. The absence of recognized classification criteria contributes to delays in diagnosis for individual patients and hampers research into SS due to small sample sizes and heterogeneously diagnosed patient populations. To address these issues, the ongoing Sjören's International Collaborative Clinical Alliance (SICCA) was funded under a US National Institutes of Health contract beginning in 2003. The SICCA project has the goals of 1) designing and implementing an international SS registry for collecting and storing clinical data and biospecimens; 2) developing standardized classification/diagnostic criteria for SS that are universally applicable; and 3) providing these resources for future studies of SS funded by the NIH or comparable agencies.
