PRIMARY ATTACK RATE OF RF 
FOLLOWING STREPTOCOCCAL 
PHARYNGITIS 
◦ EPIDEMICS: 3% 
◦ SPORADIC:0.3%
RF is a delayed autoimmune response to Group A streptococcal pharyngitis, and 
the clinical manifestation of the response and its severity in an individual is 
determined by host genetic susceptibility, the virulence of the infecting organism, 
and a conducive environment
AAGGEENNTT 
 Beta-haemolytic streptococci 
can be divided into a 
number of serological groups 
on the basis of their cell-wall 
polysaccharide antigen 
 Serological group A 
(streptococcus pyogenes) can 
be further subdivided into 
more than 130 distinct M 
types. 
 The available evidence does 
not link streptococci in Non-group 
A types with the 
pathogenesis of rf and rhd
Group A streptococci are the most common 
bacterial cause of pharyngitis, with a peak 
incidence in children 5–15 years of age. 
15–20% of sore throats are caused by group A 
streptococci. 
A patient with a true infection is at risk of 
developing RF and of spreading the organism 
to close contacts, while this is not thought to 
be the case with carriers 
Positive throat culture rate for Gr A 
streptococci are around 13.5% in Northern 
India in sore throat cases.

Chronic streptococcal “carrier” states do not 
trigger the development of RF. 
The role of group A streptococcus infection is 
complex and repeated infection is necessary 
to prime the immune response, quantitatively 
and qualitatively ,before the first episode of 
ARF occurs
HOST FACTORS 
An inherited susceptibility to ARF and RHD is 
supported by twin studies that have found a 
significantly increased concordance in 
monozygotic twins compared with dizygotic 
twins.

 First episodes of ARF 
are most common just

than age 45 years
HHOOSSTT FFAACCTTOORRSS 
In many populations, ARF and RHD are more 
common in females than males 
◦ ?Innate susceptibility, 
◦ ? Increased exposure to group a 
streptococcus because of greater 
involvement of women in child rearing, 
◦ ?Or reduced access to preventive medical 
care for girls and women.

rheumatic fever and rheumatic heart disease
PATHOGENETIC PATHWAY FOR ARF AND RHD
THE IMMUNE RESPONSE 
 Myosin is not present in cardiac valves, so how can an immune response against 
myosin induce valvulitis? 
 The initial damage to the valve might be due to the presence of laminin, another 
alpha-helical coiled-coil molecule present in the valvular basement membrane 
and around endothelium, and which is recognised by T cells 
 There is also evidence that antibodies to cardiac valve tissues cross-react with N-acetyl 
glucosamine in group A carbohydrate. 
 An exaggerated antibody response to group A carbohydrate was noted in 
patients with ARF, and titres remained raised in individuals with residual mitral 
valve disease, providing further support for the notion that these antibodies 
cause valve damage
Immune complexes may produce 
nondestructive synovitis of the joints in 
patients with ARF and nondestructive 
reactions in the basal ganglia observed in 
Sydenham's chorea, whereas cell mediated 
autoimmune cytotoxic reactions may destroy 
heart valves.
Are spheroidal or fusiform 
distinct tiny structures or 
granulomas, 1-2 mm in 
size, occurring in the 
interstitium of the heart in 
RF. 
Especially found in the 
vicinity of small blood 
vessels in the myocardium 
and endocardium and 
occasionally in the 
pericardium. 
Lesions similar to the 
aschoff nodules may be 
found in the extracardiac 
tissues .

2002–2003 WHO criteria for the diagnosis of 
rheumatic fever and rheumatic heart disease 
(based on the revised Jones criteria) 
These revised WHO criteria facilitate the 
diagnosis of: 
— A primary episode of RF 
— Recurrent attacks of RF in patients without 
RHD 
— Recurrent attacks of RF in patients with RHD 
— Rheumatic chorea 
— Insidious onset rheumatic carditis 
— Chronic RHD.
DEFINITIONS 
Recurrence: A new episode of rheumatic fever following another 
GABHS infection; occurring after 8 week following stopping 
treatment 
Rebound: Manifestations of rheumatic fever occurring within 4-6 wk 
of stopping treatment or while tapering drugs. 
Relapse: Worsening of rheumatic fever while under treatment and 
often with carditis. 
Sub clinical carditis: When clinical examination is normal but 
echocardiogram is abnormal. Around 30 percent of patients 
having chorea present as subclinical carditis. 
Indolent carditis: It is a common entity in our country. Patient 
presents with persistent features of CHF, murmur and 
cardiomegaly.

Due to an acute hemodynamic overload on the 
left ventricle from acute/ subacute mitral 
and/or aortic regurgitation. 
Myocarditis (alone) in the absence of 
valvulitis is unlikely to be of rheumatic 
origin. It should always be associated 
with an apical systolic or basal diastolic 
murmur.
PPEERRIICCAARRDDIITTIISS 
 Rheumatic pericarditis is relatively less common 
clinically and is present in up to 15% patients. 
 Since pericarditis neither results in tamponade nor 
constriction and clears up without leaving a residue, its 
limited clinical significance lies in the fact that it 
provides clear cut evidence for the presence of active 
carditis as well as active RF. 
 Pericarditis does not occur in the absence of clinical 
findings indicative of valvulitis. 
 Simultaneous demonstration of valvular involvement 
generally considered essential.
CONGESTIVE HEART FAILURE 
Least common but most serious 
manifestation. 
Occurs in5 to 10% of first attacks 
of carditis. 
More common in children <6yrs of 
age.
MMaalliiggnnaanntt rrhheeuummaattiicc ffeevveerr 
Severe disease with multi valvular 
lesions, gross cardiac enlargement, and 
congestive failure can occur in young 
patients, and such children show more 
symptoms of congestive failure than of 
rheumatic disease. 
This severe disease may be due in large 
measure to a lack of rest during the 
initial carditis
The wide difference in the reported prevalence of carditis 
in the first attack could thus be related to clinically 
undiagnosed carditis in the first attack which becomes 
apparent after recurrences of acute RF

Erythema marginatum usually 
occurs early in the course of a 
rheumatic attack. 
It may, however, persist or recur for 
months or even years, continuing 
after other manifestations of the 
disease have subsided, and it is not 
influenced by anti-inflammatory 
therapy. 
Nodules and erythema marginatum 
tend to occur together
 The latent period between streptococcal infection and 
onset of RF is shortest in arthritis and erythema 
marginatum and longest in chorea with carditis and 
subcutaneous nodules in between. 
 Atleast 1/3 rd of cases of acute rheumatic fever may 
present with inapparent streptococcal infections 
Arthralgia and fever are termed “minor” 
clinical manifestations of RF in the jones

1. The mitral valve is most often involved 
2. Mitral regurgitation is the most common finding on color flow imaging. 
3. Mitral regurgitation in rheumatic carditis is related to ventricular dilatation 
and/or restriction of leaflet mobility. 
4. Rheumatic carditis does not result in congestive heart failure in the absence of 
hemodynamically significant valve lesions.

 Echocardiographic demonstration of valvular 
regurgitation is not a prerequisite for the diagnosis of 
rheumatic carditis and should not be considered a 
limitation where the facilities are not available. 
 Currently, data do not allow subclinical valvular 
regurgitation detected by echocardiography to be 
included in the Jones criteria, as evidenceof a major 
manifestation of carditis.

develop atrial fibrillation (AF). 
 Atrial fibrillation occurs more 
commonly in older patients and is 
associated with a poorer 
prognosis, with a 10-year survival 
rate of 25% compared with 46% in 
patients who remain in sinus 
rhythm.
The mortality of untreated patients with 
MS is due to 
1.Progressive pulmonary and systemic 
congestion in 60% to 70%, 
2.Systemic embolism in 20% to 30%, 
3.Pulmonary embolism in 10%, 
4. Infection in 1% to 5%. 
Serial hemodynamic and Doppler-echocardiographic 
studies have reported 
annual loss of MV area ranging from 0.09 
to 0.32 cm2.
Mitral regurgitation can be alone 
or with other lesions 
As high as 70% of MR in initial 
attack can disappear over a period 
of time. 
If AS is present with MV 
involvement it is likely to be 
rheumatic

 Clinical and physiopathological findings in 108 patients 
with mitral stenosis who were below the age of 20 years. 
 History of at least one attack of rheumatic fever was 
obtained in 71 (66%), and of more than one attack in 
30(28%) patients. 
 Chorea and subcutaneous nodules appeared infrequently 
(3%), and erythema marginatum was conspicuously 
absent. 
 High prevalence of congestive heart-failure (45%) 
 Low prevalence of atrial fibrillation (6%) 
 The estimated mitral-valve area was less than 1 sq. Cm. In 
most of the patients 
 Isolated mitral stenosis in patients below the age of 20 
with rheumatic heart-disease is common in india. 
 Boys are affected oftener than girls
SSuujjooyy rrooyy 
 The frequency of atrial fibrillation was found to 
increase with each decade, reaching 40% in patients 
over the age of 40. 
 Angina(12%) is due to functional impairment of the 
coronary flow caused by limitation of the cardiac 
output. 
 Absence of calcification in the mitral valve and of 
thrombi could be due to the youth of the patients. 
 Severe pulmonary hypertension with gross pulmonary 
vascular obstruction, fairly normal cardiac output

In developing countries, mitral stenosis is severe 
enough to require commissurotomy before the age of 
20 or even 15 years.

MANAGEMENT ASPECTS 
PPRRIIMMAARRYY PPRREEVVEENNTTIIOONN OOFF 
AARRFF 
Treatment of GAS pharyngitis with a single 
intramuscular injection of 1.2 million units of 
benzathine penicillin G is the most reliable way 
to prevent primary attacks of ARF
SSeeccoonnddaarryy pprroopphhyyllaaxxiiss 
 Defined as the continuous 
administration of specific 
antibiotics to patients 
with a previous attack of 
rheumatic fever, or 
documented RHD 
 Purpose is to prevent 
colonization or infection of 
the upper respiratory 
tract with group A beta-hemolytic 
streptococci 
and the development of 
recurrent attacks of 
rheumatic fever 
 After surgery or 
intervention secondary 
prophylaxis should be 
continued 
 IMPORTANCE of 
secondary prophylaxis 
1. Prevents reccurences 
2. Reduces new cardiac 
damage, 
3. Facilitate resolution of 
previous damage 
4. Reduces mortality due to 
RHD. 
5. The risk of reccurence is 
highest in first year after 
an index attack of RF
WHO GUIDELINES 2004
WHO GUIDELINES 2004
SSeeccoonnddaarryy pprroopphhyyllaaxxiiss 
Because of the high infection rate 
in India, it has been suggested that 
penicillin should be given once 
every 3 rather than 4 weeks to 
maintain adequate blood levels 
during reinfection, and this has 
certainly resulted in a fall in the 
infection rate.

  • 31. Group A streptococci are the most common bacterial cause of pharyngitis, with a peak incidence in children 5–15 years of age. 15–20% of sore throats are caused by group A streptococci. A patient with a true infection is at risk of developing RF and of spreading the organism to close contacts, while this is not thought to be the case with carriers Positive throat culture rate for Gr A streptococci are around 13.5% in Northern India in sore throat cases.

  • 36. Nonsuppurative sequel, such as RF and RHD, are seen only after group A streptococcal infection of the upper respiratory tract. Bramhanathan et al 2006 Exception: skin infection leading to RF described in some aborginal tribes of australia Chronic streptococcal “carrier” states do not trigger the development of RF. The role of group A streptococcus infection is complex and repeated infection is necessary to prime the immune response, quantitatively and qualitatively ,before the first episode of ARF occurs
  • 37.

HHOOSSTT FFAACCTTOORRSS  First episodes of ARF are most common just before adolescence, wane by the end of the second decade, and are rare in adults older than age 35 years.  Recurrent episodes are especially frequent in adolescence and early adulthood, and occasional cases are seen in people older than age 45 years
  • 40. HHOOSSTT FFAACCTTOORRSS In many populations, ARF and RHD are more common in females than males ◦ ?Innate susceptibility, ◦ ? Increased exposure to group a streptococcus because of greater involvement of women in child rearing, ◦ ?Or reduced access to preventive medical care for girls and women. In populations exposed to rheumatogenic group A streptococci, the lifetime cumulative incidence of ARF is 3% to 6%.

  • 49. THE IMMUNE RESPONSE  Myosin is not present in cardiac valves, so how can an immune response against myosin induce valvulitis?  The initial damage to the valve might be due to the presence of laminin, another alpha-helical coiled-coil molecule present in the valvular basement membrane and around endothelium, and which is recognised by T cells  There is also evidence that antibodies to cardiac valve tissues cross-react with N-acetyl glucosamine in group A carbohydrate.  An exaggerated antibody response to group A carbohydrate was noted in patients with ARF, and titres remained raised in individuals with residual mitral valve disease, providing further support for the notion that these antibodies cause valve damage

  • 68. PPEERRIICCAARRDDIITTIISS  Rheumatic pericarditis is relatively less common clinically and is present in up to 15% patients.  Since pericarditis neither results in tamponade nor constriction and clears up without leaving a residue, its limited clinical significance lies in the fact that it provides clear cut evidence for the presence of active carditis as well as active RF.  Pericarditis does not occur in the absence of clinical findings indicative of valvulitis.  Simultaneous demonstration of valvular involvement generally considered essential.

  • 86. Erythema marginatum usually occurs early in the course of a rheumatic attack. It may, however, persist or recur for months or even years, continuing after other manifestations of the disease have subsided, and it is not influenced by anti-inflammatory therapy. Nodules and erythema marginatum tend to occur together
  • 87.  The latent period between streptococcal infection and onset of RF is shortest in arthritis and erythema marginatum and longest in chorea with carditis and subcutaneous nodules in between.  Atleast 1/3 rd of cases of acute rheumatic fever may present with inapparent streptococcal infections Arthralgia and fever are termed “minor” clinical manifestations of RF in the jones diagnostic criteria, because they lack diagnostic specificity

Mitral regurgitation in rheumatic carditis is related to ventricular dilatation and/or restriction of leaflet mobility. 4. Rheumatic carditis does not result in congestive heart failure in the absence of hemodynamically significant valve lesions. 5. In a quarter of patients with rheumatic carditis, valve nodules were present that may represent echocardiographic equivalents of rheumatic verrucae

  • 93.  Echocardiographic demonstration of valvular regurgitation is not a prerequisite for the diagnosis of rheumatic carditis and should not be considered a limitation where the facilities are not available.  Currently, data do not allow subclinical valvular regurgitation detected by echocardiography to be included in the Jones criteria, as evidenceof a major manifestation of carditis.
