Article: Valvular heart disease in systemic lupus erythematosus and Jaccoud's arthropathy.
[show abstract] [hide abstract]
ABSTRACT: Jaccoud's arthropathy (JA) was initially described as a secondary complication to rheumatic fever (RF). However, most recently described cases are associated with systemic lupus erythematosus (SLE). At least in RF, this articular complication has been observed to occur in association with valvular heart disease. The aim of this work is to investigate the presence of valvulopathy in patients with SLE and JA, when compared to lupus patients without such complication. Patients with diagnosis of SLE based on the American College of Rheumatology criteria were enrolled in the study and divided into two groups: with or without JA and evaluated by transthoracic echocardiography. A total of 113 patients with SLE (25 with JA and 88 without JA) were assessed, of which 108 were females and five were males. Echocardiographic changes were found in 24 patients (21.2%) out of the entire population, including valvulopathy in 17 cases (15%), pulmonary hypertension in 7 cases (6.2%) and pericardial effusion in 2 cases (1.8%). In general, echocardiographic changes were more frequently seen in the JA group in comparison with the control group (p = 0.04). Additionally, in the JA group, valvulopathy was found in nine cases (36%) against eight cases (9%) in the control group (p = 0.001). This study reveals for the first time the association between the presence of valvular heart disease and JA in SLE patients, suggesting that the presence of JA may be a marker of such complication. Additional studies are required for clarification of the mechanisms involved in both complications.Rheumatology International 10/2009; 31(1):49-52. · 1.88 Impact Factor -
Article: Profile of autoantibodies in Jaccoud's arthropathy.

ABSTRACT: To compare the frequency of different autoantibodies in a group of patients with Jaccoud's arthropathy (JA) secondary to systemic lupus erythematosus (SLE) with those without JA. A group of SLE patients with JA was compared with another group of SLE patients without this complication, matched by age and gender, regarding the presence of autoantibodies. Antibodies to cyclical citrullinated peptides (anti-CCP) and to mutated citrullinated vimentin (anti-MCV) as well as anti-SSA/Ro, anti-SSB/La, anti-Sm and anti-RNP and anticardiolipin (aCL) antibodies were searched by ELISA, using commercial kits. Rheumatoid factor was determined by nephelometry and antinuclear and anti-dsDNA antibodies by IIF. Forty-eight individuals were included in the study, being 24 patients with JA and 24 without JA, matched by gender and age. The frequency of anti-CCP antibodies in the whole population was 12.5% (6 cases), with no difference between the 2 groups. Anti-MCV antibodies were detected in 10.4% (5 cases), being found only in those with JA (p=0.05). There was no association between the presence of JA and aCL, anti-Sm, anti-RNP and anti-SSB/La antibodies. On the other hand, a statistically significant association between the presence of anti-dsDNA antibodies and JA was observed (p=0.04) as well as a marginal association with a decrease in serum levels of C3 (p=0.06). In the present study, there was an association between the presence of JA and anti-dsDNA antibodies, and anti-MCV antibodies were found only in those SLE patients with JA. Whether these antibodies have an etiopathogenic role in JA is entirely unknown.Joint, bone, spine: revue du rhumatisme 04/2009; 76(4):356-60. · 2.25 Impact Factor
