Which of the following is not a component of Jones criteria for diagnosing acute rheumatic fever: March 2008
**Core Concept**
The Jones criteria are a set of guidelines used to diagnose acute rheumatic fever (ARF), a complication of untreated or inadequately treated streptococcal pharyngitis. The criteria are divided into major and minor manifestations, with the presence of two major or one major and two minor manifestations, plus evidence of a recent group A beta-hemolytic streptococcal (GABHS) infection, required for the diagnosis.
**Why the Correct Answer is Right**
The Jones criteria include five major and nine minor manifestations. The major manifestations are: carditis, polyarthritis, chorea, erythema marginatum, and subcutaneous nodules. The minor manifestations are: fever, arthralgia, previous rheumatic fever or rheumatic heart disease, elevated erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP), and prolonged P-R interval on electrocardiogram (ECG).
**Why Each Wrong Option is Incorrect**
**Option A:** This option should list the Jones criteria's major and minor manifestations. If it doesn't, it's incorrect. The correct Jones criteria should be listed to determine what is not included.
**Option B:** This option should be a correct component of the Jones criteria. If it's not listed among the Jones criteria, it's incorrect.
**Option C:** This option should be a correct component of the Jones criteria. If it's not listed among the Jones criteria, it's incorrect.
**Option D:** This option should be a correct component of the Jones criteria. If it's not listed among the Jones criteria, it's incorrect.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the Jones criteria are used to diagnose acute rheumatic fever, not rheumatic heart disease. Rheumatic heart disease is a long-term consequence of untreated or inadequately treated ARF.
**Correct Answer:** A.
