Spondyloarthritis primarily affects the spine and joints. Linked to a disorder of the immune system, this disease has recently benefited from treatments capable of delaying its development. From the first signs to treatment.
As with many autoimmune diseases, we do not know exactly the cause of this disruption of the immune system which begins to attack the joint. However, we know that there are “genetic predispositions”. But the occurrence of the disease also requires other environmental factors that remain to be identified.
Characteristic signs are nighttime pain in the spine, joints, rib cage, morning stiffness at the same level, pain in the buttocks on rocking, fatigue, heel pain, joint swelling, finger or sausage toe… These signs may be accompanied by extra-articular signs (red or painful eye, intestinal inflammation or psoriasis…).
Most commonly, the joints affected are the sacroiliac joints and those of the spine. But other joints can also be affected the heel, hips, knees, shoulders, ankles or wrists. In advanced forms, even the rib cage can be affected, which can handicap breathing.
The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) is a questionnaire to calculate the activity index of ankylosing spondylitis. Rate the intensity of 5 symptoms during the past week, giving a score from 0 to 10, knowing that 0 means the absence of the symptom and 10 its presence at the highest degree. This score is an aid in monitoring ankylosing spondylitis.
