Many important clinical questions concerning primary Sjogren's syndrome (pSS) remain, that can only be adequately addressed by prospective cohorts. Thus, a better knowledge of the clinical outcome, the course of disease activity and the risk factors of lymphoma requires the setting up of cohorts with biobanks. The homogeneous collection of clinical data, disease activity, patient-related outcome, and biological samples, in Read More

Sjogren's syndrome (SS) is an autoimmune inflammatory disorder of exocrine glands. SS particularly affects the lacrimal and salivary glands. Dry mouth and dry eyes are frequently proffered as presenting symptoms, but nonspecific symptoms such as malaise and fatigue, and extraglandular manifestations like purpura, polyneuropathy and arthritis are also often present. Moreover, lymphomas develop in about 7.5% of SS pati Read More

There is growing evidence that epigenetics, the study of heritable changes in gene expression that do not involve mutations in the DNA itself, may play an essential role in autoimmune diseases (AID). In Sjogren's syndrome (SS), a chronic AID characterized by an epithelis of the exocrine glands, epigenetic studies have focused on three mechanisms: DNA methylation and its consequences including human endogenous retrovirus ( Read More

Patients with primary Sjogren's syndrome (pSS) have an activated type I interferon (IFN) system that contribute to the etiopathogenesis and clinical manifestations of the disease. The type I IFN system consists of the stimuli for type I IFN production, the receptors, cells and transcription factors involved in the synthesis of type I IFNs, the type I IFN-receptor and the effects on target cells. Increased type I IFN activity has been dem Read More

Sjogren's syndrome is a systemic autoimmune condition centred around salivary gland dysfunction and atrophy. There are a plethora of antibodies that mark the decline of the salivary glands, most of which relate to apoptopic mediated destruction of acinar cells. The best known of these autoantibodies, anti-Ro and anti-La form part of the diagnostic criteria for the condition. An emerging viewpoint in recent years is that gl Read More

T cells have originally occupied central stage of the debate on the type of lymphocytes governing the pathogenesis of Sjogren's syndrome (SS). However, B cells has since been substituted for T cells, and insights into their functions have revealed that they accomplish various tasks. Beyond the paradigm that T lymphocytes maintain strict control over B lymphocytes, these latter cells solicit their own help from the former, rel Read More

The strategy for a comparability assessment is developed on a hierarchical risk-based approach. Critical analysis of physicochemical and biological characterization assays is essential for the development of a good comparability protocol. Therefore, selection and sensitivity of these assays is very important. This article discusses a case study to evaluate the sensitivity of various methods in a comparability assessment of three Read More
