What autoimmune diseases cause si joint pain?

Lupus: long-term autoimmune disease in which the body's immune system becomes overactive and attacks normal, healthy tissue. Symptoms include inflammation, swelling, and damage to the joints, skin, kidneys, blood, heart, and lungs. Many patients with lupus have sacroiliac joint pain as one of their symptoms. Sacroiliitis is a painful inflammation of the sacroiliac joint that is particularly difficult to diagnose.

Sacroiliitis is related to inflammatory arthritis of the spine. Inflammation can have different causes, such as autoimmunity, microtrauma, exercise and, in some cases, infections. Sacroiliitis may also be associated with Crohn's disease, inflammatory bowel disease, ulcerative colitis, and gout. There are different diagnostic techniques for joint inflammation.

Imaging techniques, such as simple radiography, can show narrowing of the joint space, fusion, bone erosion, and ligament tightening. If not properly diagnosed and managed, sacroiliitis can become chronic. Maintaining muscle strength supports and stabilizes the sacroiliac joints, increases muscle flexibility and makes standing, sitting, bending down, lifting objects and walking less painful. Ankylosing spondylitis (AD) is a type of inflammatory arthritis that primarily affects the spine.

Ankylosing spondylitis is an inflammatory disease of the spine, sacroiliac joints, and sometimes of the extra-articular structures, including the eye. It is also known as Marie-Strümpell disease. The cause of ankylosing spondylitis is unknown, but autoimmune mechanisms have been implicated. Approximately 90% of patients with ankylosing spondylitis have the histocompatibility antigen, human leukocyte antigen (HLA) B-27, as opposed to 7% of the general population.

The importance of this fact is unknown, but this antigen provides the basis for a test to aid in the diagnosis of the disease. Ankylosing spondylitis occurs three times more frequently in men, and symptoms usually appear in the third decade of life. The onset of the disease after the age of 40 is rare. Sacroiliitis is a painful condition that affects one or both sacroiliac joints.

These joints are where the lower part of the spine and the pelvis meet. Sacroiliitis can cause pain and stiffness in the buttocks or lower back, and the pain can affect one or both legs. Standing or sitting for a long time or climbing stairs can make the pain worse. Using this technique, they also found that the lateral branches of the dorsal sacroiliac branch of S1-S3 were affected by sacroiliac joint pain.

Muscles and joints move through stretching, resistance and applying gentle pressure to the periarticular structures. Exercise can prevent age-related changes in muscles, bones, and joints and can also reverse these changes. Pain in the sacroiliac joint and surrounding structures can occur as lower back, pelvic, buttock, or sacrum pain in patterns that vary widely. The normally elastic tissue of the tendons and ligaments of the joint is eroded and replaced first by fibrocartilage and finally by bone.

These two joints are formed by the bone structure above the coccyx, known as the sacrum, and the upper part of the pelvis, known as the ilion. Structural changes in the sacroiliac joints on a pelvic x-ray of a patient with ankylosing spondylitis. The pain worsens as the disease progresses, and nighttime flare-ups with significant sleep disturbances are common. All of these variants occurred in different patients and each patient's joint looked different.

Tenderness is common in the spine, sacroiliac joints, the costesternal junction, and the trochanters major. No single diagnostic technique can detect sacroiliac joint dysfunction with high sensitivity and specificity. For example, an antitrullinated cyclic peptide was found in a patient who was initially diagnosed as seropositive for rheumatoid arthritis with sacroiliac joint involvement. AD is a chronic, seronegative inflammatory arthropathy that classically affects the axial skeleton (back), but can also affect the hips, shoulders and peripheral joints.

Doctors have different opinions about joint movement and about the degree of mobility that should be considered “normal”, as it varies from person to person. Although IL-1 may be involved in sacroiliitis, there is no direct evidence of its presence in joint biopsies. .
