PURPOSE: Primary Sjögren's syndrome is a multisystem autoimmune disease characterized by hypofunction of salivary and lacrimal glands and possible multi-organ system manifestations. Over the past 15 years, three sets of diagnostic criteria have been proposed, but none has included salivary gland ultrasonography. However, recent studies support its role in the diagnosis and prognostic evaluation of patients with Sjögren's syndrome. This study aimed to determine the value of salivary gland ultrasonography in the diagnosis and prognosis of Sjögren's syndrome by relating ultrasonography severity scores to clinical and laboratory data...

OBJECTIVES: The presence of anti-Ro/SSA and anti-La/SSB antibodies has been linked with autoimmunity in general and with several autoimmune diseases (AID) in particular. In the current study we evaluated these antibodies in a wide spectrum of AID as well as the links between them and anti-infectious antibodies. METHODS: We examined 2082 sera from patients with 16 different AID compared to 524 sera from geographically-matched healthy controls, for the presence and titres of anti-Ro/SSA and anti-La/SSB...

While the relationship between maternal connective tissue diseases and neonatal rashes was described in the 1960s and congenital heart block in the 1970s, the "culprit" antibody reactivity to the SSA/Ro-SSB/La ribonucleoprotein complex was not identified until the 1980s. However, studies have shown that approximately 10-15% of cases of congenital heart block are not exposed to anti-SSA/Ro-SSB/La. Whether those cases represent a different disease entity or whether another antibody is associated has yet to be determined...

OBJECTIVES: Saccharomyces cerevisiae is a common yeast used in the food industry. IgG and IgA antibodies against the phosphopeptidomannan of the S. cerevisiae cell wall (ASCA) are a well known marker of disease severity in Crohn's disease. Moreover, a number of studies assessed ASCA in several systemic and organ-specific autoimmune diseases postulating molecular mimicry as a possible link between ASCA and autoimmunity. However, since they have never been tested in primary Sjögren's syndrome (pSS), the purpose of this study was to investigate these antibodies in a large cohort of pSS patients, compared to healthy donors (HD), and their significance as potentially helpful biomarker in a clinical setting...

AIMS: Autoantibodies targeting Ro52 and Ro60 antigens are historically reported as anti SSA/Ro. In general anti SSA/Ro results are either anti Ro52+Ro60+ or anti Ro52-Ro60+ antibodies. Anti Ro52 without anti Ro60 (Ro52+ Ro60-) antibodies are often not reported routinely. This study intends to review the potential significance of these autoantibodies in the management of connective tissue diseases. METHOD: A retrospective survey of Ro52+Ro60- was carried out as part of the service evaluation of extractable nuclear antigen antibodies (ENA) reporting from the immunology laboratory, the NHS Greater Glasgow and Clyde (GGC), UK...

Background/purpose To plan a quality improvement project, we need to understand the practice patterns of physicians. We undertook an online survey of systemic lupus erythematosus (SLE) patients and physicians providing care to SLE patients to determine the patterns of medical care provided to SLE patients. Materials and methods Two self-report surveys were developed. A 12-item survey for the patients and a 13-item survey for physicians enquired about longitudinal care for SLE. Surveys were administered online to physicians providing care to SLE patients, and to patients who self-identified as having SLE, through the Lupus Society of Illinois...

BACKGROUND: Interferon (IFN)-α is thought to have a pivotal role in systemic lupus erythematosus (SLE), and type III IFNs (IFN-λ) were recently also associated with SLE. In this study, we measured levels of IFN-α, IFN-λ1, and related cytokines, such as IL-17A, IL-23, and interferon-γ-induced protein 10 (IP-10), in a Karolinska University Hospital cohort of patients with SLE and control subjects. The objective of the study was to investigate if cytokine measurements could identify different subsets of patients with active SLE and higher disease damage...

  Neonatal lupus (NL), a passively-acquired autoimmune disease associated with maternal anti-SSA antibody, presents both cardiac manifestations such as cardiac NL and non-cardiac manifestations including rashes, cytopenia, and hepatic abnormalities. Cardiac NL, occurring in 1-2% of anti-SS-A antibody-positive mothers, is a life-threatening complication with a mortality rate of 20% and a pacemaker implantation rate of 70%. In contrast, cutaneous NL, which is more common than cardiac NL, usually resolves in six months...

Neonatal lupus erythematosus is an autoimmune disease resulting from the trans-placental passage of maternal anti-SSA/Ro, anti-SSB/La, and less frequently anti-RNP antibodies to the foetus. At the time of diagnosis 50% of mothers are asymptomatic. Neonatal manifestations of this multisystem disease may include congenital heart block, cutaneous lesions and haematological abnormalities. We present the case of congenital neonatal lupus erythematosus in non-identical twins, showing variability in clinical manifestation of this disease,despite receiving the same level of antibodies from the mother...

PURPOSE OF REVIEW: To provide new insights into pathogenesis, prevention and management of cardiac manifestations of neonatal lupus (cardiac neonatal lupus) and issues pertinent to all anti-SSA/Ro positive individuals of childbearing age. RECENT FINDINGS: Antibody specificity with high risk for cardiac neonatal lupus remains elusive, but high titers of Ro60, Ro52 or Ro52p200 antibodies appear to be required. Varying antibody specificities to the p200 region of Ro52 can induce first-degree block in a rodent model...

To inform our ongoing efforts to develop defining features to be incorporated into a novel set of classification criteria for discoid lupus erythematosus (DLE), we conducted a literature review using the Ovid MEDLINE database. A search was performed to identify studies reporting criteria used to distinguish DLE from other cutaneous lupus erythematosus subtypes. We examined which clinical, histopathologic, and serologic features have data to support their use as effective features in distinguishing DLE from other potential disease mimickers and cutaneous lupus subsets...

RATIONALE: Peripheral neurological complications in primary Sjögren's syndrome (pSS) seem the most common, however the involvement of central nervous system (CNS) remains unclear. While abnormalities in pSS revealed by brain magnetic resonance imaging (MRI) are usually small discrete hyperintense areas in the white matter on T2-FLAIR weighted MRI, massive brain lesions have been rarely reported, particularly in bilateral basal ganglia. PATIENT CONCERNS: A 51-year-old woman exhibited dizziness, slurred speech and hemiplegia as a manifestation of pSS...
