[Streptococcal rheumatic fever in adults]

Area of Science:

• Rheumatology
• Infectious Diseases
• Cardiology

Context:

• Streptococcal rheumatic fever is a significant cause of morbidity, particularly in adults.
• Understanding adult presentations is crucial for timely diagnosis and management.
• This study examines a cohort of adult patients diagnosed with streptococcal rheumatic fever.

Purpose:

• To describe the clinical characteristics, diagnostic findings, and treatment outcomes of streptococcal rheumatic fever in adults.
• To investigate the association between streptococcal infection and rheumatic fever manifestations in this demographic.
• To evaluate the efficacy of standard treatments for adult rheumatic fever cases.

Summary:

• Thirty-seven adult cases of streptococcal rheumatic fever were analyzed, with a mean age of 33 years.
• Common symptoms included severe joint pain, predominantly in lower limbs, and cardiac involvement such as mitral regurgitation and ECG abnormalities.
• Elevated antibody titers (antistreptolysins and antistreptokinases) confirmed streptococcal infection in most patients.
• Throat swabs were often negative during the rheumatic attack, underscoring diagnostic challenges.
• All patients responded well to antibiotics and anti-inflammatory drugs, with most achieving cure within a month, though some experienced prolonged illness.

Impact:

• Provides valuable insights into the epidemiology and clinical spectrum of streptococcal rheumatic fever in adults.
• Highlights the importance of considering rheumatic fever in adults presenting with suggestive symptoms, even with negative throat swabs.
• Emphasizes the effectiveness of current therapeutic strategies in managing adult rheumatic fever, leading to favorable prognoses in the majority of cases.
