Time to use ultrasound and not stethoscopes for rheumatic heart disease screening.

“Although echocardiography is of established value in the evaluation and management of acute and chronic rheumatic heart disease (Doppler is more sensitive than auscultation for detecting valvular regurgitation), physiological valvular regurgitation can be detected by Doppler in normal individuals. Because pathological and physiological regurgitation are not distinct entities but are part of a continuum, the challenge is to distinguish physiological from pathological valvular regurgitation.”

It was the opinion of the working group that Doppler echocardiographic findings alone should not be classified as either a major or minor Jones criterion in the guidelines for the diagnosis of acute rheumatic fever at this time.

Artrite

Poliartrite migrante, coinvolgimento delle grandi articolazioni, rapida risposta ai FANS, autolimitantesi, assenti sequele .

Artrite reattiva post streptococcica

Presentation of the disease up to 10 days after

the infection, prolonged arthritis or arthritis

that is recurrent for 2 months and lack of

response to ASA or other NSAID.

Shulman and Ayoub (Curr Opin Rheumatol 2002;14:562-5), the AHA, and the Red Book of the AAP17 suggest that antibiotic prophylaxis be given for 1 year, and if no carditis is observed, then prophylaxis should be discontinued”.

Methods. Pediatric study participants (np160) were followed during a 2-year study with monthly throat cultures (np3491) and blood samples (np1679) obtained every 13 weeks. Recovered GAS were characterized; serum anti–streptolysin O and anti–

DNase B antibody titers were determined. Antibody

titers and GAS culture results were temporally

correlated and analyzed.

Risposta immune “classica”

Infezione documentata da SBEA, seguita da incremento significativo di TAS e antiDNAsiB.

• 58 infezioni da SBEA in 45 soggetti: 20 (34,5%) risposta

“classica”

(22)

Risposta di 1 solo anticorpo

Infezione documentata da SBEA, seguita da incremento significativo di TAS o antiDNAsiB.

• 58 infezioni da SBEA in 45 soggetti: 36 (62,1%) risposta di

un solo Ab (28 TAS, 28 antiDNAsiB

Valori normali

These data document the very real potential for misinterpretation of streptococcal antibody titers.

These studies strongly reinforce observations that the documented increase in titer is the most reliable indicator of infection

Attempting to define GAS infection,

especially time of infection onset, on the

basis of a single timepoint or widely

spaced observations can lead to

erroneous interpretations.
