Significance of silent carditis and investigation of follow-up signs in acute rheumatic fever

AIM

This study aimed to demonstrate the importance of ECHO in the diagnosis and long-term follow-up of silent carditis.

MATERIAL & METHODS

This study included 182 (157 arthritis; 25 chorea) patients out of 214 patients who had been diagnosed with acute rheumatic fever for the first time. All of the patients were scanned with ECHO between specific intervals.

RESULTS

While there was no recovery observed in isolated aortic insufficiency during long-term follow-up, recovery in isolated mitral insufficiency was found. As the follow-up time of the mitral and aortic insufficiencies became longer, there was an increase in recovery in aortic insufficiency.

CONCLUSION

Follow-up results of silent carditis support that ECHO should be among the major criteria used to diagnose rheumatic carditis.

Cost-effectiveness analysis of rheumatic heart disease prevention strategies

Rheumatic heart disease (RHD), secondary to group A streptococcal infection is endemic in the developing as well as parts of the developed world with significant costs to the patient, and to the healthcare system. We briefly review the prevalence and cost of RHD in developed and developing nations. We subsequently develop a Markov model to evaluate the cost-effectiveness of three strategies (vs standard no prevention) for preventing RHD in a developing world country: primary prophylaxis (throat swab to detect and subsequently treat group A streptococci as needed); primary prophylaxis (antibiotic prophylaxis for all) with benzathine penicillin G once monthly to all patients (ages 5-21 years) regardless of evidence of infection; and secondary prophylaxis with monthly only to those with echocardiographic evidence of early RHD. Our model suggests that echocardiographic screening and secondary prophylaxis is the best strategy although the strategies change depending on parameters used.
