Introduction Acute Rheumatic fever (RF) is a multisystem inflammatory disorder presenting with self limited migratory arthritis. It may be also accompanied or followed by carditis, and less frequently by chorea and skin involvement. It is related to post-infectious autoimmune mechanisms driven to group A streptococcus antigens. Jones criteria are the main diagnosis guidelines, by combining major and minor signs at presentation. There is no single biologic marker, and the disease course is characterized by relapse after re-exposure to streptococcal antigens. 1 6 It is estimated that carditis may occur in up to 60% of the cases. 5,6 Rheumatic valvular disease may be caused by a single severe attack, but it is often related to recurrent attacks. However, relapsing risks should be considered even for RF mild forms. Epidemiology According to WHO, 7 at least 15 6 million people have RHD, 300 000 of about 0 5 million individuals who acquire ARF every year go on to develop RHD, and 233 000 deaths annually are directly attributable to ARF or RHD. However, these estimates are based on conservative assumptions, so the true disease burden is likely to be substantially higher. Furthermore, the overall quality of epidemiological data from developing countries is poor, particularly with respect to research documenting the incidence of ARF. 7 The incidence of rheumatic fever in developed countries is in the range of 0.2 to 0.5 per 1000 but that for developing countries is variable from place to place reaching as high as 20 per 1000 children living in Johannesburg, South Africa. The prevalence of RHD increases with age, peaking in adults aged 25 34 years, reflecting ARF activity in previous decades. 8 In young patients, mitral valve regurgitation is the predominant cardiac lesion, but mitral stenosis becomes progressively more common with increasing age. 9 This trend, whereby the incidence of ARF peaks in childhood and adolescence, but the prevalence of RHD peaks in adulthood, has been documented in studies done in the USA, in Aboriginal Australians, in India, and in Burma, and is likely to be seen in all populations with high ratesof RHD. 10,11,12 In many populations, ARF and RHD are more common in females than males.40 Whether this trend is a result of 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 is unclear. II. Aims and Objectives We have recently diagnosed quite a few number of cases of Acute rheumatic fever over a short period of six months. We report them in this case series. Case 1 Dipika dao a 18 yr. old female patient presented with dyspnoea on exertion for 1 year, palpitations for 2 months.

There is h/o pulmonary kochs 6 months back, h/o severe excruciating joint pain and fever is present when she was 11 years old which subsided after taking pain killers without leaving any joint deformity. On examination the BP is 100/60, pulse is 112/min and normal in rhytm and there is decreased air entry in the left lower chest,abdominal and CNS systems are normal, CVS examination revealed the apex is located in lt. 5 th ics 2 cm lateral to MCL a mid diastolic murmur in apex with opening snap is heard, a middiastlolic murmur is also heard in the right Lower sternal edge which is increased on inspiration. On investigating Hb is 10.1 gm/dl, ESR & CRP are within normal and rest of the reports are within normal range. Echocardiography showed severe MS, mild AR, severe TR and severe PAH.

Pulmonary component of second heart sound was prominent. ECG showed prolonged PR interval. Echocardiography showed anterior and posterior mitral valve thickened, severe mitral regurgitation, moderate tricuspid regurgitation. Ejection fraction was preserved at 69%. III. Discussion The exact mechanism streptococcal throat infection result in rheumatic fever is not known. There is neither direct invasion nor toxin-mediated damage to the tissues involved. The most popularly accepted theory is immune mediated damage, where antibodies produced against streptococcal antigen cross reacts with host tissue (like cardiac muscles, synovial and brain tissues, among others).the m-protein is an antigenically variable cell wall component in some of these bacteria. There are more than 80 subtypes but m-subtypes 1,3,5,6 and 18 are most often associated with acute rheumatic fever. The main clinical features of ARF are outlined in the Jones Criteria, which were established in 1944 and then modified, revised twice, 13,14 and updated (panel) 15 by the American Heart Association. Every revision increased the specificity but decreased the sensitivity of the criteria, 16 largely in response to the steadily declining incidence of ARF in developed countries. In regions of the world where ARF is endemic or epidemic, however, and where the risk associated with missed diagnoses lack of provision of secondary prophylaxis to prevent recurrent ARF and worsening RHD might outweigh the consequences of over-diagnosis, the 1992 Jones criteria might not now be sufficiently sensitive. As such, the 2002 03 WHO criteria8 which, among other things, specified less stringent requirements for the diagnosis of recurrent ARF in patients with established RHD should probably be adopted (panel). The Jones and the WHO criteria are only diagnostic guidelines, however, and should be adapted in certain circumstances, for example to increase sensitivity of diagnosis in populations at high risk of ARF. Jones criteria (1992) 15 Panel: Diagnosis of AR 15,16 Two major or one major and two minor manifestations must be present, plus evidence of antecedent group A streptococcus infection Chorea and indolent carditis do not require evidence of antecedent group A streptococcus infection Recurrent episode requires only one major or several minor manifestations, plus evidence of antecedent group A streptococcus infection Major manifestations Carditis 1) Polyarthritis 2) Chorea 3) Erythema marginatum 4) Subcutaneous nodules Minor manifestations 1) Arthralgia 2) Fever 3) Raised erythrocyte sedimentation rate or C-reactive protein concentrations DOI: 10.9790/0853-1510065559 www.iosrjournals.org 57 Page

4) Prolonged PR interval on electrocardiogram Resurgence Of Acute Rheumatic Fever And Rheumatic Heart Disease? A Case. Evidence of antecedent group A streptococcus infection 1) Positive throat culture or rapid antigen test for group A streptococcus 2) Raised or rising streptococcal antibody titre WHO criteria (2002 03) 16 Chorea and indolent carditis do not require evidence of antecedent group A streptococcusinfection First episode As per Jones criteria 15 Recurrent episode In a patient without established RHD: as per first episode In a patient with established RHD: requires two minor manifestations, plus evidence of antecedent group A streptococcus infection. Evidence of antecedent group A streptococcus infection as per Jones criteria, but with addition of recent scarlet fever Rheumatic Fever is a public health concern due to carditis and heart damage, which may be aggravated by late diagnosis and poor penicillin prophylaxis adherence. A systematic evaluation of patients care is important to define further strategy for disease control and treatment. Arthritis was the most frequent major sign, followed by carditis in the present case series. Arthritis had migratory or additive pattern in most of our cases, affecting predominantly large joints as described originally in the 1950 s. The migratory pattern predominated in lower limbs. Presentation with symmetric small joints, neck, and hip arthritis involvement, as well as longer duration was not observed. Small joints, cervical spine involvement and longer arthritis duration need a differential diagnosis with post-streptococcal reactive arthritis, but in the pediatric age range this feature is still a matter of controversy, where it possibly represents an atypical RF profile. Concomitant arthritis and carditis was seen in most of our cases, carditis the second most frequent major sign, and mitral valve was the most frequent valve to get involved. None of the patients reported of Chorea, Subcutaneous nodules, Erythema marginatum An important clue for diagnosis ascertainment is high or rising titres of antistreptolysin-o. In our series almost all had high antistreptolysin-o titres. IV. Conclusion ARF prevalence has fallen in many developed countries, however it is still a challenge for doctors who work in developing countries. In the present study we have tried to present clinical aspects of ARF and RHD patients presenting in the Department of Medicine. In spite of the limitations of small case series study, the study reinforce the need for early diagnosis and long term surveillance, in order to get better disease control to prevent heart damage.
