  • Title: [Anti PM-Scl antibodies. Study of prevalence and of meaning].
    Author: Gaudin C, Fortenfant F, Adoue D, Beyne-Rauzy O.
    Journal: Rev Med Interne; 2006 Sep; 27(9):665-70. PubMed ID: 16797795.
    Abstract:
    OBJECTIVE: The purpose of our study is to appreciate the prevalence of antibodies anti PM-Scl within the framework of antinuclear antibodies detection and to clarify clinical biological and evolutive features associated to these antibodies. METHODS: 9,747 consecutive antinuclear testing datas allowed us to evaluate anti PM-Scl antibodies frequency. A retrospective analysis of patients characteristics was performed to identify clinical, biological and evolutive signs associated with this antibody over a five years follow up period. RESULTS: Over the 9,747 samples tested for antinuclear antibodies detection, 3,493 (35.8%) are positive. An anti ENA activity is observed in 727 (7.5%) cases and anti PM-Scl in 6 (0.06%). These antibodies are described in systemic sclerosis, myositis or overlap syndromes. All theses diseases showed a low evolutivity over the five years of follow up. CONCLUSIONS: Low prevalence and possible association with an overlap autoimmune syndrome of quite good prognosis are reported with anti PM-Scl antibodies.
