Ankylosing spondylitis is not directly related to AIDS. Ankylosing spondylitis is an autoimmune disease, which may be caused by infection, surrounding environment, endocrine, genetic factors, etc. It mainly involves the sacroiliac joints of the patients, and will gradually spread upward with the development of the disease, which will easily cause spinal fibrous adhesion and intervertebral osteophytes, resulting in pain, stiffness and deformation of the spine, etc. AIDS is a human immunodeficiency virus infection, which can attack the human immune system and eventually lead to cellular immune deficiency. HIV is a human immunodeficiency virus infection that can attack the human immune system, ultimately leading to cellular immune deficiencies in patients. When HIV is transmitted through blood, sexual intercourse, and mother-to-child transmission, it may cause the patient to develop symptoms such as fever, which usually lasts for 1 to 2 weeks and is accompanied by symptoms such as sore throat, weakness of the limbs, nausea and vomiting. Therefore, ankylosing spondylitis and AIDS are two diseases and are not directly related. If you are suffering from ankylosing spondylitis and AIDS, you should seek medical advice from your doctor.
