High anti-O (antibody) itself is not harmful to the body, but it may be indicative of streptococcal infection, patients suffering from acute rheumatic fever, chronic rheumatic heart disease, etc. Prolonged streptococcal infection can lead to tonsillitis, pharyngitis or scarlet fever.
1. Acute rheumatic fever: patients are characterized by upper respiratory tract infection, redness, swelling, heat, large joint pain, some patients have subcutaneous nodules, annular erythema and other skin symptoms, but also chest tightness, asphyxia, arrhythmia and other manifestations of carditis, especially in adolescent patients, there are complex neurological symptoms, even if mild choreoathetosis, limbs can not be moved on their own.
2. Chronic rheumatic heart disease: it mainly involves valves, including mitral and aortic valves, with valve stenosis and closure insufficiency. Clinically, it mainly manifests as heart failure symptoms, including chest tightness, asphyxia, edema or atrial fibrillation.
3. Tonsillitis, pharyngitis, scarlet fever: the increase of long-term anti-O antibody indicates the existence of hidden streptococcal infection in the body and poor immunity, at this time, the possibility of patients suffering from tonsillitis, pharyngitis, scarlet fever will increase.
When the patient’s anti-O antibody is high, he should go to the hospital in time, and under the guidance of the hospital to carry out the correct treatment.
