I'm 52 and my ASO titer is 459. Could this affect my heart or kidneys? What precautions should I take?

An elevated ASO (anti-streptolysin O) titer can indicate a recent streptococcal infection. This infection can potentially lead to complications such as rheumatic fever, which can affect the heart and kidneys. To prevent complications, it is important to treat the underlying streptococcal infection with antibiotics. In this case, you can take a course of antibiotics such as Penicillin V at a dosage of 500mg four times a day for 10 days. Additionally, it is important to follow up with your healthcare provider for monitoring and further management. It is also advisable to rest, stay hydrated, and maintain a healthy lifestyle to support your recovery
