We analyzed a one-year consecutive population of 624 patients referred by clinicians to the immunology laboratory to investigate anti-SS-A and/or anti-SS-B autoantibodies, who were detected using luminex technology.

Characteristic of the 15 patients with CTD are presented in Table 2. [, In primary Sjögren’s syndrome, HLA class II is associated exclusively with autoantibody production and spreading of the autoimmune response. This study included 11 patients with isolated anti-SS-B of whom only 2 patients were diagnosed as suffering from CTD, namely pSS.

The fluorescence pattern was diffuse or centromere in 8 (53%) CTD patients.

By consequence, we can suggest that searching anti-SS-B autoantibodies in case of ANA negativity is not necessary. Data curation, They showed that participants with anti-SSB alone were comparable to those with negative SS-A/SS-B serology for the SS key phenotypic features.

The median age of these patients was 50 years (range 3–91 years); and 80% were female. Arthralgia were the most frequent symptoms in 10 patients (67%), of whom 3 had arthritis, predominantly in SLE and RA patients. None of the patients required further immunosuppressive therapy. on What is Sjögren’s syndrome?

The short answer is that it could be because of declining hormonal levels related to menopause. Data curation, However, anti-SSA antibodies alone are often found in lupus, particularly in limited forms of the disease. We therefore found here that the clinical value of isolated anti-SS-B autoantibodies was strongly related to the positivity of ANA by indirect immunofluorescence technique. Diagnosing Sjögren’s syndrome can be challenging as they vary from person to person and change in type and severity over time. We would like to show you a description here but the site won’t allow us. Given the lack of predictive value of organ involvement related to CTD and the absence of correlation between anti-SS-B autoantibody titers and CTD diagnosis, the isolated positivity of anti-SS-B autoantibodies does not provide additional clinical support in medical decision.

All RA patients received methotrexate, 2 were treated with anti-TNF. Anti-nucleosome, anti-U1-RNP, anti-Sm, and anti-JO1 were analyzed with the same technique. Four cases of RA were diagnosed, with typical symmetric and bilateral arthritis. [. Anti-CCP antibodies and rheumatoid factor (RF) were detected using a Luminex technology (Bioplex) and a nephelometry technique (Dade Behring), respectively. Department of Nephrology, Hospices Civils de Lyon, Centre Hospitalier Lyon Sud, Hospices Civils de Lyon, Claude Bernard University Lyon 1, University of Lyon, Lyon, France, Affiliation Anti-Ro antibodies are found in 60 to 90% of patients with Primary Sjögren’s syndrome and 30 to 40% of patients with SLE who appear to fall into specific subsets. In our study, 40% of patients with isolated anti-SS-B had positive ANA, but patients with CTD had significantly more often positive ANA than patients without CTD. Isolated anti-SS-B positivity was reported as suggestive of cutaneous lupus and pSS in one series of patients [4]. Undifferentiated CTD was diagnosed if objective criteria were present, but not sufficient for the diagnosis of overt CTD, in addition to positive antinuclear autoantibodies (ANA) [13]. One author had access to identifying information, but patient records and information were anonymized and de-identified prior to analysis. (2017) Isolated positive anti-SS-B autoantibodies are not related to clinical features of systemic autoimmune diseases: Results from a routine population survey. Copyright: © 2017 Jardel et al. Low titers between 1 and 2 AI of anti-SS-B autoantibodies were detected in both non-CTD (32 [53%] of 60 patients of anti-SS-B) as well as in CTD (9 [60%] of 15 patients) (p = 0.78). Categorical variables were compared using the chi-squared statistic or Fisher’s exact test. We found a prevalence of 12%, which is similar to a previous series using 2 different techniques, i.e immunodiffusion and line immunoassay [4]. High and low values | Lab results explained, What is Beta-Aminoisobutyric Acid?

The clinical characteristics and diagnosis of connective tissue diseases (CTD) were retrieved according to the international criteria. The presence of both antibodies (SS-A and SS-B) strengthen the diagnosis of Sjögren’s Syndrome and conveys prognostic information. Clinical and animal model evidence indicates that estrogen and androgens like DHEA promote gland cell survival and protect against exocrine gland inflammation; and these hormone levels decline at menopause.

Arthralgia was the more frequent sign and encountered in 10 patients (67%), of whom 3 had arthritis. in some people who are genetically predisposed to the disorder. disease, with all cases divided roughly in half between the two: has a strong female propensity and is more prevalent in Caucasian women, with the mean age of onset usually in the 40s. Within the CTD population, the presence of isolated anti-SS-B was not significantly associated to characteristic indicating a specific syndrome.

The results of the present series advocate in favor of the decision of the Rheumatology/European League Against Rheumatism Classification Criteria classification to omit anti-SS-B for the diagnosis of pSS. Click through the PLOS taxonomy to find articles in your field.

Anti-SS-A and anti-SS-B autoantibodies were analyzed by a Luminex technology with the manufacturer’s threshold of positivity at 1 Antibody Index (AI) (Bioplex 2200, Biorad, Marnes la Coquette, France). Eighty-four patients (13.5%) were positive only for anti-SS-B autoantibodies.
