Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Antibiotic therapy for streptococcal infection
If active streptococcal infection is present, appropriate antibiotics are prescribed to eradicate the bacteria and prevent complications such as rheumatic fever. Treatment decisions are based on clinical symptoms and confirmatory testing.
Antimicrobial or antiviral therapy
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Serial antibody titer monitoring
Regular blood tests to track deoxyribonuclease B antibody levels over time, as elevated titers can persist for months after infection. Monitoring helps assess disease progression and response to treatment.
Additional treatment options
Supportive care and rest
Adequate rest, hydration, and symptom management during recovery from streptococcal infection. This supports the immune system in clearing the infection naturally.
lifestyleImmune-supportive nutrition
Balanced diet rich in vitamins C, D, and zinc to support immune function during and after infection. Adequate protein intake helps tissue repair and immune cell production.
dietaryProbiotic supplementation
Probiotics may help restore healthy gut flora during and after antibiotic treatment, potentially reducing gastrointestinal side effects and supporting overall immune health.
