Pericarditis may be the initial manifestation of systemic lupus erythematosus. Although it is known that antinuclear antibody can be detected in the serum of patients with a wide variety of diseases, it has been proposed that the detection of antinuclear antibody in serosal fluid is a sensitive and specific test for determining that effusions are due to systemic lupus erythematosus. A case is presented in which antinuclear antibody in high titer was identified in the pericardial fluid of a patient who was found at autopsy to have a primary cardiac lymphoma. The case indicates that antinuclear antibody detected in serosal effusions should not be considered pathognomonic for systemic lupus erythematosus.

Recurrence is one of the major complications of pericarditis. Treatment of recurrence is often difficult, and immunosuppressive drugs or surgery may be necessary. We conducted an open-label prospective study of nine patients (seven men and two women; age, 18-64 years; mean age, 41.7 +/- 13.7 years). Patients were treated with colchicine (1 mg/day) to prevent recurrences. All patients had suffered at least three relapses despite treatment with acetylsalicylic acid, indomethacin, prednisone, or a combination. Pericarditis was classified as idiopathic in five patients, postpericardiotomy in two, post-myocardial infarction in one, and associated with disseminated lupus erythematosus in one. For statistical analysis, we conducted a paired comparison design (Student's t test). All patients treated with colchicine responded favorably to therapy. Prednisone was discontinued in all patients after 2-6 weeks (mean, 26.33 +/- 10.9 days), and colchicine alone was continued. After a mean follow-up of 24.3 months (minimum, 10 months; maximum, 54 months), no recurrences were observed in any patient; there was a significant difference between the symptom-free periods before and after treatment with colchicine (p less than 0.002). Our study suggests that colchicine may be useful in avoiding recurrence of pericarditis, although these results need to be confirmed in a larger, double-blind study.

Determinations of anti-histone antibodies (AHA) by ELISA were carried out in 109 cases of SLE, 117 of RA, the positive rate being 50.5%, 23.1% respectively, with titres in SLE patients higher than in RA. AHA was 90.2% positive in active cases of SLE patients. SLE patients with AHA showed a higher incidence of pericarditis and arthritis, but a lower rate of malar rash than SLE patients without AHA. In RA, there is a higher incidence of extraarticular manifestations in AHA positive patients IgM-AHA was this predominant AHA in RA while in SLE patients it was the IgG-AHA. For SLE, IgG-AHA which was more closely associated with anti-ds DNA was more significant than IgM-AHA.

Free Sm was purified by gel filtration and anti-Sm affinity chromatography. Using this purified antigen, an ELISA for anti-Sm was performed. Three hundred and fifty patients with various rheumatic diseases were studied with respect to immunoglobulin classes of anti-Sm by ELISA. A high frequency of IgG anti-Sm was specifically detected in patients with systemic lupus erythematosus (SLE), but IgA and IgM anti-Sm showed a low frequency and also was detected in other diseases. In patients with SLE, anti-Sm significantly correlated with lung fibrosis and pericarditis. In our longitudinal study, there were increases in titer of IgG anti-Sm preceding central nervous system exacerbation and serositis. IgG anti-Sm was found to be not only a diagnostic marker but also a reliable measure of disease activity in SLE.

Pericarditis is one of the most frequent manifestations of systemic lupus erythematosus; however, purulent pericarditis and tamponade are rare. We describe a patient with systemic lupus erythematosus and culture-proven gonococcal arthritis who developed purulent pericarditis with intracellular gram-negative diplococci. Evidence of tamponade was seen on echocardiography. There has not been a reported case of Neisseria gonorrhoeae in pericardial fluid or tissue since the introduction of antibiotics.

Despite the high frequency of both pericardial involvement and of infectious complications in SLE, septic pericarditis is uncommon. We report here a patient with SLE who developed tamponade due to Salmonella infection. Most of the other eight recorded cases of septic pericarditis in SLE were due to Staphylococcus aureus and none has been previously attributed to Gram-negative bacteria.

A case of systemic lupus erythematosus is reported in a woman aged 41 years with exudative pericarditis as the predominating manifestation of the disease. Attention is called to the diagnostic usefulness of demonstration of LE cells in pericardial effusion.

In order to investigate the clinical significance of autoantibodies to individual U small nuclear ribonucleoprotein (snRNP) polypeptides, an enzyme-linked immunosorbent assay (ELISA) using isolated 68K, A, B/B', and D polypeptides from purified U1 snRNP was developed. The ELISA levels of IgG antibodies were positively correlated with results of immunoblotting and hemagglutination. In patients positive for antibodies to ribonucleoprotein, IgG anti-68K reactivity was associated with active mixed connective tissue disease, and in particular with myositis and esophageal hypomotility. IgG B/B' and D polypeptide reactivities were associated with systemic lupus erythematosus and renal disorder. Raynaud's phenomenon was infrequent in patients with high IgG B/B' and D polypeptide reactivities. Pleuritis/pericarditis was associated with the IgG B/B' polypeptide reactivities. In longitudinal studies, ELISA levels of IgG antibodies against these polypeptides changed in parallel with disease activity.

Systemic lupus erythematosus (SLE) is a disease of unknown etiology in which many organs are damaged by deposition of pathogenic autoantibodies and immune complexes Clinically lupus nephritis occurs about 50% in SLE Many studies revealed the association between autoantibodies and lupus nephritis However, the pathogenetic role of autoantibodies in lupus nephritis remains obscure. To elucidate the pathogenetic role of anti-SSA antibody in lupus nephritis, 32 patients with SLE were evaluated by serological and histological methods. Enzyme-linked immunosorbent assay for anti-SSA antibody was developed for this study. It was confirmed that this assay was specific, did not detect autoantibodies other than anti-SSA antibody. The levels of anti-SSA antibody determined by this assay significantly correlated with the levels determined by double immunodiffusion (p less than 0.01). The level of anti-SSA antibody greater than or equal to 200 units was regarded as positive. The serum levels of antinuclear antibody, anti-DNA antibody, anti-RNP antibody, anti-SSA antibody, anti-SSB antibody, C3, and C4 were also determined. Renal biopsy materials were evaluated according to the WHO criteria, and activity index (AI), chronicity index (CI), and pathologic score (PS) were calculated according to Austin et al. The patients were divided into group A (AI greater than or equal to 4, n = 17) and group B (AI less than or equal to 3, n = 15) The levels of anti-DNA antibody were significantly higher in group A than in group B (p less than 0.05). The frequency of positive anti-SSA antibody in group A (70.6%) was greater than in group B (23.3%) significantly (p less than 0.05). However, there were no differences in the levels of anti-nuclear antibody, anti-DNA antibody, anti-RNP anti-body, anti-SSA antibody, anti-SSB antibody, C3, and C4 between group A and group B. Then these patients were divided into group I (anti-SSA greater than or equal to 200 units, n = 17) and group II (anti-SSA less than 200 units, n = 15). AI and CI were greater than in group I than in group II significantly (p less than 0.05). The frequency of pericarditis in group I (35.3%) was greater than group II (6.7%) (p = 0.061), but the frequencies of the other clinical manifestations were not different. AI was correlated with anti-DNA antibody significantly (p less than 0.01), but there were no correlations between other serological data and parameters.(ABSTRACT TRUNCATED AT 400 WORDS)

Although pericarditis is the most common cardiac complication of systemic lupus erythematosus (SLE), cardiac tamponade is distinctly unusual. We report one patient whose initial predominant manifestation of SLE was cardiac tamponade and review the cases of 12 patients with similar presentations.
