Acute rheumatic fever is an inflammatory disease that can affect the heart, joints, brain, and skin. It occurs as a complication of untreated strep throat infection. Major symptoms include heart inflammation, arthritis, abnormal movements, skin nodules, and rashes. It is diagnosed based on symptoms and evidence of prior strep infection. Treatment involves antibiotics to treat strep, aspirin or steroids to reduce inflammation, and lifelong antibiotics to prevent recurrence. Nursing care focuses on reducing fever, monitoring the heart for damage, maintaining activity, and educating patients about prevention and management of the disease.
2. DEFINITION:
2
Acute rheumatic fever is a systemic disease of
childhood ,often recurrent that follows group A
beta hemolytic streptococcal infection
It is a diffuse inflammatory disease of connective
tissue primarily involving heart, blood vessels,
joints, subcut.tissue and CNS

3. Incidence
3
In developing areas of the world, severe disease
caused by group A Streptococcus (e.g., ARF,
rheumatic heart disease, glomerulonephritis, and
invasive infections) is estimated to affect nearly
20 million people and is the leading cause of
cardiovascular death during the first five decades
of life. ARF can occur at any age, although most
cases occur in children 5 to 15 years of age.
Worldwide, there are 470,000 new cases of ARF
and 233,000 deaths attributable to ARF or
rheumatic heart disease each year. Most cases
occur in developing countries and among 5/30/2016
4. Etiology
5/30/20164
Group A Beta hemolytic Streptococcus
pyogenes
Malnutrition
Poverty
overcrowding.
Incidence more during fall ,winter &
early spring
5. Pathophysiology
5
Rheumatic fever is a sequela to
group A beta- hemolytic
streptococcal infection that
occurs in about 3% of untreated
infections. It is a preventable
disease through detection and
adequate treatment of
streptococcal pharyngitis.
Connective tissue of the heart,
blood vessels, joints and
subcutaneous tissues can be
affected.
Lesions in connective tissue are
known as Aschoff bodies, which
are localized areas of tissue

Heart valves, mainly the
mitral valve, are affected
resulting in valve leakage
and narrowing.
Compensatory changes
in the chamber sizes and
thickness of chamber
walls occur.
Heart involvement
(pancarditis) also
includes pericarditis,
myocarditis, epicarditis
and endocarditis.
7. Pathologic Lesions
7
Fibrinoid degeneration of connective tissue,
inflammatory edema, inflammatory cell infiltration
& proliferation of specific cells resulting in
formation of Ashcoff nodules, resulting in-
Pancarditis in the heart
Arthritis in the joints
Ashcoff nodules in the subcutaneous tissue
Basal gangliar lesions resulting in chorea

Criteria was established by
T.D. Jones in 1944 revised
by the American Heart
Association and modified by
WHO to provide a basis for
diagnosis, the presence of
two major criteria or one
major and two minor criteria
plus evidence of a
preceding group A
streptococcal infection
indicates a high probability
of ARF. 5/30/2016

14. Medical management
5/30/201614
Anti-microbial therapy—penicillin is the drug of
choice
Rest to maintain optimal cardiac function.
Salicylates or NSAIDS or corticosteroids
Periodic prophylaxis throughout life
Beta blockers, ACE inhibitors, digoxin, diuretics,
supplemental oxygen, rest, sodium and fluid
restrictions to manage heart failure
Phenobarbital and diazepam to manage chorea

Step I - primary prevention
(eradication of streptococci)
Step II - anti inflammatory treatment
