HLA-B27 positivity does not usually affect a patient’s life expectancy when treated regularly. HLA-B27 positivity suggests that ankylosing spondylitis may be present, but standardized treatment of this type of disease generally does not affect life expectancy. Ankylosing spondylitis has an insidious onset and a slow course. In the early stages of the disease, patients often experience dull pain in the lumbosacral region and morning stiffness, which gradually decreases after activity. There is no cure for this type of disease. The disease can be slowed down by general treatment (e.g., reasonable aerobic exercise, keeping the chest upright when standing or sitting, etc.), medication (e.g., celecoxib, thalidomide, etc.), and surgical treatments (e.g., total hip arthroplasty, orthopedic spine surgery, etc.). If the disease is delayed to an advanced stage, it is difficult to reverse and should be diagnosed and treated early. In the event of an abnormal HLA-B27 test result, it is recommended that you seek prompt medical attention and targeted treatment or therapy with the help of your doctor.
