Sjogren syndrome a chronic autoimmune disease

There are treatments that bring relief, though. You should be able to keep doing all the things you love to do without making many changes. Conditions like this are called autoimmune diseases.

Sjogren syndrome a chronic autoimmune disease

Cause[ edit ] The cause of SS is unknown, but it may be the influence of a combination of genetic, environmental, and other factors—as is the case with many other autoimmune disorders. Although the numerous factors contributing to the progression of this disease have made it difficult to find out the exact origin and cause, major advances over the past decade have contributed to a proposed set of pathogenic events that occur prior to the diagnosis of SS.

Although this explains the more obvious symptoms e. This suggests that the disease begins with increased activity in the interleukin 1 system, followed by an autoregulatory up-regulation of IL-1RA to reduce the successful binding of interleukin 1 to its receptors.

Interleukin 1 likely is the marker for fatigue, but increased IL-1RA is observed in the CSF and is associated with increased fatigue through cytokine -induced sickness behavior. Seropositivity for anti-Ro and anti-La is associated with greater severity and longer duration of disease, and findings of their high abundance from the salivary glands of SS patients suggests their imperative role in the pathogenesis of SS.

This indicates viral reactivation and inability of lymphoid infiltrates to control EBV replication in SS, leading to the initiation or perpetuation of an immune response in target organs.

Nonetheless, it remains to be clarified exactly how reactivation of EBV is induced in lesions of patients with SS, and which specific molecular mechanisms are involved in the process of viral reactivation.

Environmental and hormonal factors, in concert with an appropriate genetic background, are believed to trigger SS, which dysregulates epithelial cells and allows aberrant homing and activation of dendritic cells DCsT cells, and B cells. Following the migration of lymphocytes into the glands in response to chemokines and specific adhesion moleculesT cells interact with epithelial cells.

The early accumulation of plasmacytoid dendritic cells in the target tissues, which produce high levels of type 1 IFNs, seems important, as these cells can further dysregulate the immune response through abnormal retention of lymphocytes in the tissues and their subsequent activation.

BAFF stimulates aberrant B-cell maturation, leading to the emergence of self-reactive B cells, which locally produce autoantibodies, in a germinal centre -like structure GC-likewhich is also the location of lymphomagenesis origin of lymphoma.

Both the Fas and Fas ligand proteins are overexpressed in primary SS patients, while expression of BCL-1which is known to downregulate apoptosis, was found significantly reduced in acinar and ductal epithelial cells of SS patients compared to healthy people.

Reduced apoptosis was also implicated in the accumulation of autoreactive B-cells found in the glands. The relationship of autoantibodies expressed in SS with apoptosis is still being researched.

Also, patients with SS symptoms approach different specialities for treatment, which can make diagnosis difficult. Since dry eyes and dry mouth are very common symptoms, and frequently occur in people over 40, people often think the symptoms are age-related and ignore them.

However, some medications can cause symptoms similar to those of SS. The combination of several tests, which can be done in a series, can eventually diagnose SS.

Blood tests can be done to determine if a patient has high levels of antibodies that are indicative of the condition, such as antinuclear antibody ANA and rheumatoid factor because SS frequently occurs secondary to rheumatoid arthritiswhich are associated with autoimmune diseases.

The rose bengal test uses a stain that measures state and function of the lacrimal glands. This test involves placing the non-toxic dye rose bengal on the eyes.

Any distinctive colour change can indicate SS, but confirming the condition requires many related diagnostic tools. This measurement analysis varies among people depending on other eye-related conditions and medications in use when the test is taken.

Symptoms of dry mouth and dryness in the oral cavity are caused by the reduced production of saliva from the salivary glands parotid glandsubmandibular glandand sublingual gland.

To check the status of salivary glands and the production of saliva, a salivary flow-rate test is performed, in which the person is asked to spit as much as they can into a cup, and the resulting saliva sample is collected and weighed.

Not enough saliva produced could mean the person has SS. A resultant collection of less than 1.Sjögren’s syndrome is an example of an autoimmune syndrome. In autoimmune disorders, the immune system, which normally protects the body from infection and cancers, may cause injury to the body’s own tissues.

Sjögren syndrome is an autoimmune disorder in which the body's immune system mistakenly reacts to the tissue in glands that produce moisture, such as tear and salivary glands. It is a chronic, inflammatory disease that often progresses to a more complex, systemic disorder that can affect other tissues and organs in the body such as joints.

Other individuals with secondary Sjogren’s may have lupus, scleroderma, primary biliary cirrhosis, or a different kind of autoimmune disease. Sjogren’s syndrome has a very slow insidious onset. About 90% of individuals with Sjogren’s symptoms are women, and the syndrome .

Sjogren’s syndrome (SS) is a chronic autoimmune disorder in which the moisture-producing glands do not function correctly; SS can also affect internal organs. Sjogren’s syndrome is a relatively common disease, although often under-diagnosed.

Sjogren’s syndrome can occur alone or in association. It's a chronic autoimmune disease in which the white blood cells attack the glands that produce tears and saliva. Nine out of 10 people who have Sjogren's are women, according to the Sjogren's.
