[Sjögren's syndrome. New diagnostic aspects].

European criteria for classification of Sjögren's syndrome have recently been developed and evaluated. We report the clinical and laboratory findings in 96 patients with primary Sjögren's syndrome who have been classified according to these new criteria. In our patient population the latency from appearance of the first symptom to diagnosis was 11 years. In addition to sicca symptoms in mucous membranes, the dominant symptoms were periodic fatigue (92%), arthralgia (82%), hoarse voice (71%), dry cough (54%) and diarrhoea (51%). Antibodies to the nuclear antigens SSA and SSB were found in respectively 22.2% and 15.6% of the patients. Two out of ten patients with both anti-SSA and anti-SSB antibodies gave birth to a child with heart block.
