Firstly, ankylosing spondylitis is an autoimmune disease primarily characterized by the destruction of axial joints, a chronic condition that can also manifest peripheral joint lesions. Currently, there are no definitive cures, meaning long-term medication is necessary to alleviate symptoms, control disease progression, delay joint deformity, reduce disability, and improve quality of life. This constitutes the overall goal of treatment. The preferred treatments are non-steroidal anti-inflammatory drugs (NSAIDs) and biologic agents. However, before using biologic agents, it is essential to complete routine blood tests, erythrocyte sedimentation rate, C-reactive protein, screenings for infectious diseases, and tuberculosis. After excluding infections, tuberculosis, and tumors, biologic agents can be administered. During the use of biologic agents, there is a risk of reduced immunity, making it easy to contract infections. Therefore, it is important to avoid getting cold, overwork, and to regularly recheck routine blood parameters, liver, and kidney functions.

Symptoms of ankylosing spondylitis

The main symptom of ankylosing spondylitis is pain, characterized by pain in the lower back and lumbar region. The pain occurs during rest and diminishes with activity; it is especially severe at night, often waking the sufferer, who then finds mild activity alleviates the pain enough to return to sleep. As the disease progresses, chest pain and restricted rib cage movement begin, due to the disease spreading to the thoracic vertebrae and eventually reaching the cervical vertebrae in later stages, resulting in difficulty moving the neck. Early physical signs include tenderness in the sacroiliac joints and paraspinal muscles. X-rays can reveal that the sacroiliac joints are often the first to be affected, usually showing sacroiliitis. Additionally, there is a particularly high positivity rate for HLA-B27, the human leukocyte antigen B27, which can reach up to 90%, whereas it is typically around 4%-9% in the general population.

Does ankylosing spondylitis have a genetic component?

Firstly, ankylosing spondylitis is a chronic disease that primarily affects the axial joints, and this disease is incurable. It can only be managed with medications to control the progression of the disease, delay the appearance of joint deformities, and reduce disability. This is the main purpose of its treatment. The cause of the disease is also unclear, and it is somewhat related to genetics. If parents have it, the incidence in their children is significantly increased, and there is a phenomenon of familial aggregation. It cannot be considered a hereditary disease, but there is indeed a phenomenon of familial aggregation. Moreover, the incidence of the disease in children is much higher than in families without a history of the disease.

What is Ankylosing Spondylitis?

Ankylosing Spondylitis (AS), where "A" stands for fusion and "S" for spine, refers to the condition where the bones and joints of the spine are fused together. Ankylosing Spondylitis is defined as a chronic inflammatory disease primarily affecting the axial skeleton and major limb joints. It is characterized by fibrosis and ossification of the intervertebral discs’ annulus fibrosus and nearby connective tissues, as well as ankylosis (stiffening) of the joints. It presents as a sterile inflammation occurring in the spine. However, it is not solely limited to the spine as it also involves the axial bones and major limb joints. The pathological hallmark of the disease includes inflammation mainly at the sacroiliac joints and points of attachment to the spine, leading to joint stiffness and calcification of the spinal ligaments and joints. The disease progression begins at the sacroiliac joint, spreading upwards through the entirety of the spine, and eventually stops at the cervical vertebrae. Symptoms start with pain in the early stages, followed by restricted mobility in the intermediate phase, and ultimately leading to deformities of the abdomen and back, culminating in severe hunchback. The exact cause of Ankylosing Spondylitis remains unclear, with various theories proposed but none universally accepted. Additionally, it is categorized under rheumatologic and immunologic disorders.

Can ankylosing spondylitis be cured?

Based on the current situation, it is very difficult to cure ankylosing spondylitis. Ankylosing spondylitis is a chronic disease primarily affecting the spine. It mainly involves the sacroiliac joints and spine, eventually causing spinal stiffness and restricted movement. Additionally, it can cause varying degrees of damage to multiple organs such as the eyes, lungs, cardiovascular system, and kidneys. Ankylosing spondylitis is commonly referred to as AS, where 'A' stands for fusion and 'S' for spine, hence the term means spinal fusion. Currently, the cause of the disease is unknown, and there are no specific clinical treatments. The basic treatment principle involves alleviating pain, preventing spinal deformities, and strengthening the back muscles. Typically, conservative treatment is used during the early or middle stages, while surgical correction may be considered in the later stages when significant spinal deformities occur. Generally, ankylosing spondylitis is very difficult to cure.
