Mixed connective tissue disease with pulmonary hypertension: a clinical and pathological study.

Clinical and autopsy findings of 2 cases with mixed connective tissue disease (MCTD) associated with severe pulmonary hypertension are reported. Both cases showed marked intimal and medial thickening in small and medium sized pulmonary arteries. In one of the cases plexiform lesions, endarteritis obliterans, and fibrous intimal thickening of the pulmonary veins were recognized. In some cases with MCTD, pulmonary hypertension develops due to pulmonary vascular lesions which are similar to those of primary pulmonary hypertension.

Inhibition of topoisomerase I by antibodies in sera from scleroderma patients.

Purified type I topoisomerase from calf thymus as well as nuclear and cytoplasmic extracts from EGF-stimulated human and mouse fibroblasts in cell culture efficiently convert supercoiled plasmid DNA to the relaxed form. The purified IgG fraction from the sera of Japanese patients with the rheumatic disease scleroderma were shown to inhibit this relaxation activity. Thus, these patients likely produce autoantibodies to topoisomerase I. In addition, the human, bovine and murine enzymes share antigenic determinants recognized by the antisera.

Anti-Ro/SSA and -La/SSB antibodies in patients with connective tissue diseases.

The frequency of anti-Ro/SSA and anti-La/SSB antibodies in patients from Japan with Sjögren's syndrome, systemic lupus erythematosus (SLE), progressive systemic sclerosis (PSS), polymyositis-dermatomyositis (PM-DM), rheumatoid arthritis (RA) and blood donors is reported. Anti-La/SSB ab was especially detected in patients with severe glandular and extraglandular manifestation and could be found in sera years prior to the confirmation of Sjögren's syndrome. The purified Ro/SSA antigen consisted of 60 k peptide and 16 k RNA while the La/SSB antigen consisted of 41 k and 29 k peptides. Some molecular association seems to exist between the peptides and corresponding IgG anti-Ro/SSA and anti-La/SSB antibodies.
