[Eosinophilic fasciitis: analysis of a series of 10 patients].

BACKGROUND AND OBJECTIVE: Eosinophilic fasciitis is an uncommon scleroderma-like syndrome with unknown etiology and pathogenesis. We report the clinical manifestations and response to therapy in a series of patients diagnosed with eosinophilic fasciitis. PATIENTS AND METHOD: The records of 10 eosinophilic fasciitis patients seen at our hospital between 1996-2004 were reviewed. RESULTS: Five patients were males, ages ranged from 20 years to 67 years, with a mean of 59 years. Patients were followed for 33.4 (27.1) months (SD). Nailfold capillaroscopy was near normal in all patients. Only one patient had antinuclear antibody positivity, and another had an autoimmune thyroiditis. No significant relationship was detected between the eosinophil count and the extent of skin induration. The clinical course was inadequate and the treatment response poor in patients with spreading cutaneous induration (p = 0.008). These patients had more often ventilatory restriction and perimyositis. CONCLUSIONS: Eosinophilic fasciitis does not always have a good prognosis. Ventilatory restriction, perimyositis and poor treatment response are not infrequent in a series of patients attended in a general hospital.

[Undifferentiated, overlapping and mixed connective tissue diseases].

Mixed connective tissue disease (MCTD), undifferentiated connective tissue disease and overlap syndromes are autoimmune systemic diseases that must be differentiated. Antibodies against the U1-ribonucleoprotein complex --spliceosome-- allows the diagnosis of mixed connective tissue disease. Links between the immunologic and clinical phenomena are emerging. Longitudinal studies of patients with MCTD highlight the impact of pulmonary hypertension and contribute to define the disease. Immunogenetic studies hold MCTD as an independent disease.

[Fetal microchimerism in patients with primary biliary cirrhosis].

BACKGROUND: Fetal microchimerism (FM) has been implicated in the pathogenesis of primary biliary cirrhosis (PBC). The aim of the study was to investigate the presence of FM in PBC patients. PATIENTS AND METHOD: FM was studied in 28 women, 14 with PBC and 14 healthy controls.DNA was extracted from peripheral blood cells, and a PCR analysis to detect a specific Y-chromosome sequence was performed. Specificity was confirmed by Southern-blot analysis. RESULTS: The Y-chromosome sequence was amplified from peripheral-blood cell DNA in only one PBC patient and in none of the controls. CONCLUSIONS: FM does not seem to play a major role in patients with PBC.
