Acute rheumatic fever and Post-streptococcal reactive arthritis

Area of Science:

• Rheumatology
• Infectious Diseases
• Immunology

Background:

• Acute rheumatic fever (ARF) and poststreptococcal reactive arthritis (PSRA) are autoimmune sequelae of Group A streptococcal (GAS) infections.
• While sharing a common trigger, ARF and PSRA exhibit distinct clinical manifestations and prognoses.

Purpose of the Study:

• To review the key clinical features differentiating ARF and PSRA.
• To outline diagnostic approaches for both poststreptococcal conditions.
• To provide an overview of current management strategies for ARF and PSRA.

Main Methods:

• Literature review focusing on clinical presentations, diagnostic criteria, and treatment guidelines for ARF and PSRA.
• Comparative analysis of disease characteristics and long-term outcomes.

Main Results:

• ARF is a systemic inflammatory disorder with potential cardiac involvement (rheumatic heart disease), requiring aggressive management and prophylaxis.
• PSRA typically presents as persistent arthritis without carditis, generally resolving without lasting sequelae.
• Accurate differentiation is essential to guide treatment and prevent overtreatment.

Conclusions:

• Distinguishing ARF from PSRA is critical for effective patient care and resource allocation.
• Understanding the distinct natural histories of ARF and PSRA informs appropriate therapeutic decisions.
• This review highlights the importance of precise diagnosis in managing poststreptococcal autoimmune sequelae.
