Abstract

OBJECTIVES:
To determine the spectrum and prevalence of the varied manifestations, associated conditions and laboratory abnormalities of patients with primary Sjögren`s syndrome in Israel and compare them between individuals of Sephardic and Ashkenazi descent and with data from the literature.
METHODS:
A retrospective study of a cohort of 201 consecutive patients diagnosed and followed at a single academic medical center. All cases were diagnosed using stringent criteria according to the American European Concensus Group including a labial minor salivary gland biopsy in all cases.
RESULTS:
Patients` mean age was 57 years and 84% were women. Overall, more than 98% of patients had sicca symptoms of dry eyes and mouth. About 35% of the cohort had hematological manifestations – primarily immune cytopenias, protein immunoelectrophoresis abnormalities and lymphoma. About 20% had associated neurological conditions (not only peripheral but often central nervous system) and 15% had pulmonary involvement. In addition, thyroid disease, liver disease, vascular or cutaneous manifestations, synovitis, ocular and renal disease could be found. In fact, the presenting manifestation was extraglandular or an abnormal test result in 39% of the patients.
CONCLUSIONS:
No significant differences were found in glandular or extraglandular manifestations or laboratory test results between Ashkenazi and Sephardic patients, despite their genetic differences. A negative history of sicca symptoms effectively rules out primary Sjögren`s syndrome in this cohort. These symptoms may not be volunteered by patients and the large variety of extraglandular involvement patterns and associated conditions observed may dominate the patient`s presentation, and mandate physicians` awareness and a high index of suspicion for a timely diagnosis.
