Adult-onset acute rheumatic fever: possible resurgence in southern Taiwan.

BACKGROUND: By the late 1980s, acute rheumatic fever (ARF) had become a rare disease in Taiwan. The low prevalence rate in this area is attributed to a better economic status, which has led to improved public health and adequate medical services.

OBJECTIVES: The increasing number of patients with adult-onset ARF in the United States described in the literature prompted us to evaluate the cases diagnosed in our medical center.

METHODS: A retrospective chart review was performed for patients with arthritis from July 1988 to October 2004. To be included, patients had to meet revised Jones criteria.

RESULTS: Three adult patients with ARF have been diagnosed since June 2001, with no childhood ARF being diagnosed. All cases presented with migratory polyarthritis, whereas 1 had erythema marginatum and transient carditis. These patients responded well to treatment with antibiotics and nonsteroidal antiinflammatory drugs.

CONCLUSIONS: Clinicians must provide careful assessment and treatment to patients presenting with acute pharyngitis. A possible resurgence of ARF can be eradicated by primary prevention of streptococcal pharyngitis.
