7. WORLD RHD BURDEN
RHD REMAINS A MAJOR HEALTH
CONCERN AROUND THE GLOBE
15.6 million people have RHD in the
world .
2,82,000 cases are added each year.
2,33,000 deaths occur each year.
8. I I DI ,RHEUMATIC FEVER IS ENDEMIC
NN A
AND REMAINS ONE OF THE MAJOR CAUSES
OF CV DISEASE ACCOUNTING FOR 25%-45 %
OF ACQUIRED HEART DISEASE. INDIA IS IN
A PHASE OF EPIDEMIOLOGICAL
TRANSITION ,ON ONE HAND THERE IS
BURDEN OF RHD AND ON OTHER HAND
GOVERNMENT RESOURCES ARE SCARSE .
9. RHD in India
Prevalence: 5/1000 population of 5-15 age group
1 million RHD cases in India
Hospital admissions due to RHD is 20-30% of CVD
10. Acute rheumatic fever (ARF) is a systemic disease
of childhood
It is a delayed non-suppurative sequelae to URTI
with group A BETA-hemolytic streptococci
It is a diffuse inflammatory disease of connective
tissue,primarily involving heart,blood
vessels,joints, subcut.tissue and CNS
14. Host Factors
Age:
5-15 yrs(most susceptible)
Sex:
both
Environmental factors
over crowding, poor sanitation, poverty
Incidence more during
winter & early spring
18. 1.Arthritis
Flitting & fleeting migratory polyarthritis, involving major joints
Commonly involved joints-knee,ankle,elbow & wrist
Occur in 80%,involved joints are exquisitely tender
In children below 5 yrs:It is mild but carditis is more prominent
Arthritis does not progress to chronic disease
19. 2.Carditis
Manifest as pancarditis(endocarditis, myocarditis
and pericarditis),occur in 50% of cases
Carditis is the only manifestation of rheumatic fever
that leaves a sequelae & permanent damage to the
organ
Valvulitis occur in acute phase
Chronic phase- fibrosis,calcification & stenosis of
heart valves(fishmouth valves)

JONES CRITERIA
31. Jones Criteria (Revised) for Guidance in the
Diagnosis of Rheumatic Fever*
Major Manifestation Minor Supporting Evidence
Manifestations of Streptococal Infection
Carditis Clinical Laboratory
Polyarthritis Previous Acute phase
Chorea rheumatic reactants: Increased Titer of Anti-
Erythema Marginatum fever or Erythrocyte Streptococcal Antibodies ASO
Subcutaneous Nodules rheumatic sedimentation (anti-streptolysin O),
heart disease rate, others
Arthralgia C-reactive Positive Throat Culture
Fever protein, for Group A Streptococcus
leukocytosis Recent Scarlet Fever
Prolonged P-
R interval
*The presence of two major criteria, or of one major and two minor criteria, indicates
a high probability of acute rheumatic fever, if supported by evidence of Group A
streptococcal nfection.
32. If the patient has Chorea alone then it is
difficult to diagnose rheumatic fever
Insidious or late-onset carditis with no other
explanation
33. PITFALLS IN JONES CRITERIA
1. DIFFICULT TO DIAGNOSE ARF WHEN CARDITIS IS
ONLY MANIFESTATION SPECIALLY IN
RECCURENCE
2. SUBCLINICAL CARDITIS IS DIFFICULT TO DETECT
CLINICALLY
3. CLINICAL CARDITIS IS PRESENT BUT
SUPPORTIVE MINOR CRITERIA ARE NOT
FULFILLED
4. WHEN PREVIOUS CARDIAC STATUS IS UNKNOWN
IT IS DIFFICULT TO SAY WHETHER THE
FINDINGS ARE USUALLY ACUTE CARDITIS OR
RECURRENCE OR IT IS OLD RHD.
5. IN CASES OF POLYARTHRALGIA IF NOT
EVALUATED FOR ARF THEY WOULD GO
UNDIAGNOSED
35. GOALS OF ECHO INTERROGATION
1. IT CAN HELP IN PRECISE AND EARLY DIAGNOSIS OF ARF .
2. IT CAN PREVENT OVER DIAGNOSIS OF CARDITIS
DEPENDING ON THE TRADITIONAL CLINICAL AUSCULTATORY
FINDINGS
3. REGULAR CHECK UP WITH NON INVASIVE ECHO CAN HELP
TO EVALUATE THE STATUS OF RHD AND DECIDE FOR
ELECTIVE BALOON VALVULOPLASTY FOR MITRAL STENOSIS
AND TIMELY DECISION FOR VALVE REPAIR /REPLACEMENT
.THIS CAN REDUCE THE MORBIDITY AND MORTALITY ,BEFORE
THE PATIENT DEVELOPS CHF .

39. ROLE OF ECHO IN MANAGEMENT OF ARF IN
FUTURE
THE ECHOCARDIOGRAM IS SIMPLE ,NON-INVASIVE,REPRODUCABLE TOOL FOR
EARLY AND PRECISE DIAGNOSIS OF CARDITIS IN ARF .
THERE IS A PROPOSAL OF INCLUDING VIJAYA’S ECHO CRITERIA OF CARDITIS
AS MAJOR CRITERIA INSTEAD OF ERYTHEMA MARGIRATUM WHICH IS
IRRELEVANT ,WHENEVER THERE IS A REVISION OF JONE’S CRITERIA

cross-section. Note fine focal nodularity along the edges of the mitral valve (arrows)
suggesting verrucae. C, Electrocardiogram (lead II) with prolonged PR interval (160 ms).
45. Prevention and control
Primary prevention
• To prevent the first attack of RF,by detection and
treatment of streptococcal throat inf.
• Many inf are inapparent or undiagnosed
• High risk approach:
Surveillance for streptococcal pharyngitis
among school children
46. Primary prevention contd…
Sore throat should be swabbed and cultured
If strepto.— Give Penicillin
(If culture is not possible a sore throat can be treated
with Benzathine Benzyl Penicillin)
Dose: One IM inj.,1.2 miilion units(adults),0.6 million
units(children)
Or Oral Penicillin G/Penicillin V for 10 days
Erythromycin (In case of allergy to Penicillin)
48. Other measures in Secondary Prevention
Surveys to know the prevalence of RHD
among school children
Every 5 years in 6-14 years age group
49. Rheumatic fever can recur whenever the individual
experience new GABH streptococcal infection,If
not on prophylactic medicines
Good prognosis for older age group & if no carditis
during the initial attack
Bad prognosis for younger children & those with
carditis with valvar lesions
50. REMEMBER TOGETHER WE
CAN FIGHT RHEUMATIC FEVER
AND RHD….WE CAN HEAL THE
FUTURE OF OUR NATION AND
THE WORLD FOR SURE BY
SPREADING AWARENESS AND
TIMELY ACTION IN TREATING
THE PATIENTS .
ITS TIME TO ACT….
