Abstract
Background Acute rheumatic fever (ARF) with carditis can lead to the development of rheumatic heart disease in children and young adults. Objective This study aimed to investigate the manifestations of rheumatic carditis, clinically significant regression of valvular regurgitation as assessed by echocardiography, and the independent predictors of mitral regurgitation (MR) improvement after rheumatic carditis in Thai children. Method Children diagnosed with rheumatic carditis during 2005-2020 at Siriraj Hospital (Bangkok, Thailand) were retrospectively enrolled. Trivial, and mild regurgitation were grouped as non-clinically significant (NCS) regurgitation. Valvular regression was defined moderate-severe regurgitation improving to NCS regurgitation. Results Eighty-one patients (mean age: 10 years, range: 8-12 years) were included. At presentation, 59 (72.8%) patients had combined mitral regurgitation (MR) and aortic regurgitation (AR), 20 (24.6%) patients had MR alone, and 2 (2.4%) patients had AR alone. Concerning severity, 28 (34.6%) and 30 (37%) patients presented with severe and moderate MR, respectively. Severe and moderate AR was found in 9 (11.1%) and 16 (19.8%) patients, respectively. At the one-year follow-up, 43.4% of moderate-severe MR, and 41.7% of moderate-severe AR improved to NCS regurgitation. Multivariate analysis revealed high erythrocyte sedimentation rate (ESR) (p = 0.01) and severe carditis (p = 0.05) at presentation to be independent predictors of MR improvement. Conclusion Thai children with rheumatic carditis had a high incidence of valvular regurgitation; however, the valvular damage was improved in most patients. High ESR and severe carditis independently predict MR improvement.

Cytokine imbalance in acute rheumatic fever and rheumatic heart disease: Mechanisms and therapeutic implications. Autoimmun Rev 2022; 21:103209.

Abstract
Acute Rheumatic Fever (ARF) and Rheumatic Heart Disease (RHD) are autoimmune sequelae of Group A Streptococcus infection with significant global disease burden. The pathogenesis of these diseases is poorly understood, and no immune modulating therapies are available to stop progression from ARF to RHD. Cytokines and chemokines are immune signaling molecules critical to the development of autoimmune diseases. An increasing number of studies point to a central role for pro-inflammatory cytokines and chemokines in ARF and RHD pathogenesis, in particular IL-6, IL-8/CXCL8, and TNFα, which are elevated in circulation in both ARF and RHD patients. Histological studies of RHD valve tissue implicates Th1 and Th17 associated pro-inflammatory cytokines, chemokine CXCL9, and the fibrosis-associated cytokine TGF-β in progressive cycles of inflammatory damage and fibrotic repair. Taken together, this suggests immune molecules contribute to both the acute inflammatory disease stage of ARF, as well as cardiac remodeling and valve dysfunction in RHD. Monoclonal antibody blockade of pro-inflammatory cytokines IL-6 and TNFα are approved therapies for many autoimmune diseases and the most successful immunomodulating therapies for rheumatoid arthritis. Current evidence suggests possible benefit for ARF patients from IL-6 and TNFα blockade, in particular to interrupt progression to RHD, and warrants immediate investigation.

Abstract
We investigated outcomes for patients born after 1983 and hospitalized with initial acute rheumatic fever (ARF) in New Zealand during 1989-2012. We linked ARF progression outcome data (recurrent hospitalization for ARF, hospitalization for rheumatic heart disease [RHD], and death from circulatory causes) for 1989-2015. Retrospective analysis identified initial RHD patients <40 years of age who were hospitalized during 2010-2015 and previously hospitalized for ARF. Most (86.4%) of the 2,182 initial ARF patients did not experience disease progression by the end of 2015. Progression probability after 26.8 years of theoretical follow-up was 24.0%; probability of death, 1.0%. Progression was more rapid and ≈2 times more likely for indigenous Māori or Pacific Islander patients. Of 435 initial RHD patients, 82.2% had not been previously hospitalized for ARF. This young cohort demonstrated low mortality rates but considerable illness, especially among underserved populations. A national patient register could help monitor, prevent, and reduce ARF progression.

Abstract
The incidence of acute rheumatic fever (ARF) is 8 to 51 per 100,000 people worldwide. It most commonly affects children 5 to 15 years of age after a group A streptococcal infection. Overcrowding and poor socioeconomic conditions are directly proportional to the incidence of ARF. Rheumatic carditis is a manifestation of ARF that may lead to rheumatic heart disease (RHD). Timely treatment of group A streptococcal infection can prevent ARF, and penicillin prophylaxis can prevent recurrence of ARF. Prevention of recurrent ARF is the most effective way to prevent RHD. ARF is diagnosed using the 2015 modified Jones criteria. There is no gold standard laboratory test. Therefore, clinicians need to be aware of the clinical signs and symptoms of ARF to include in their differential diagnosis when seeing such patients. Secondary prophylaxis with benzathine penicillin G has been shown to decrease the incidence of RHD and is key to RHD control. Clinicians need to understand the implications of secondary prophylaxis for ARF. There is also a need to improve ARF diagnosis, to find novel therapies to reduce the incidence of ARF, and to reduce the prevalence of RHD. RHD research is neglected and underfunded. Thus, there is also a need for RHD advocacy and public health awareness to increase research on RHD.

Abstract
Hydroxychloroquine (HCQ) suppresses an interleukin-1β-granulocyte-macrophage colony-stimulating factor cytokine axis, reported to be dysregulated in peripheral blood mononuclear cells of acute rheumatic fever patients ex vivo. We describe HCQ treatment for 2 patients with rheumatic carditis and a protracted inflammatory course. HCQ was associated with control of inflammatory markers, control of pericarditis in first patient and stabilization of progressive carditis in the second patient.

Abstract
Acute rheumatic fever is caused by an autoimmune response to throat infection with Streptococcus pyogenes. Cardiac involvement during acute rheumatic fever can result in rheumatic heart disease, which can cause heart failure and premature mortality. Poverty and household overcrowding are associated with an increased prevalence of acute rheumatic fever and rheumatic heart disease, both of which remain a public health problem in many low-income countries. Control efforts are hampered by the scarcity of accurate data on disease burden, and effective approaches to diagnosis, prevention, and treatment. The diagnosis of acute rheumatic fever is entirely clinical, without any laboratory gold standard, and no treatments have been shown to reduce progression to rheumatic heart disease. Prevention mainly relies on the prompt recognition and treatment of streptococcal pharyngitis, and avoidance of recurrent infection using long-term antibiotics. But evidence for the effectiveness of either approach is not strong. High-quality research is urgently needed to guide efforts to reduce acute rheumatic fever incidence and prevent progression to rheumatic heart disease.

Abstract
Human immunoglobulin preparations for intravenous or subcutaneous administration are the cornerstone of treatment in patients with primary immunodeficiency diseases affecting the humoral immune system. Intravenous preparations have a number of important uses in the treatment of other diseases in humans as well, some for which acceptable treatment alternatives do not exist. We provide an update of the evidence-based guideline on immunoglobulin therapy, last published in 2006. Given the potential risks and inherent scarcity of human immunoglobulin, careful consideration of its indications and administration is warranted.

Abstract
PURPOSE OF REVIEW The purpose is to provide a broad overview of the current state of knowledge of pathogenesis, diagnosis, and management of rheumatic heart disease (RHD). RECENT FINDINGS Studies on pathogenesis of RHD have focused on autoimmunity because of molecular mimicry between the streptococcal M antigen α-helical coiled-coil structure and sarcomeric proteins such as myosin and tropomyosin. More recently, nonsarcomeric autoantigens, endothelial injury and the innate immune system have been proposed to play key roles in the pathogenesis of RHD. In the 2015 revised Jones Criteria, the importance of echocardiography and subclinical carditis in the diagnosis of acute rheumatic fever is highlighted. Experimental studies with targeted anti-inflammatory therapeutics have been largely unsuccessful and the only established treatment is still lifelong antibiotics. Efforts to improve patient selection and outcomes with percutaneous mitral balloon valvuloplasty are ongoing. With regard to surgical management, several groups have demonstrated excellent operative and midterm outcomes from valve repair as opposed to valve replacement. SUMMARY There are still many unanswered questions regarding RHD pathogenesis. The only accepted medical treatment is still long-term antibiotic therapy, whereas advances in mitral repair techniques have led to successful durable repairs being performed in high-volume, expert centers.

Abstract
INTRODUCTION Rheumatic fever (RF) incidence among New Zealand (NZ) individuals of Polynesian (Māori and Pacific) ancestry remains among the highest in the world. Polymorphisms in the IL-6, IL1RN, and CTLA4 genes have been associated with RF, and their products are modulated by new medications. Confirmation of these previous associations could help guide clinical approaches. We aimed to test IL-6, IL-1RA (IL1RN), and CTLA4 functional SNPs in 204 rheumatic heart disease (RHD) patients and 116 controls of Māori and Pacific ancestry. MATERIAL AND METHOD Self-reported ancestry of the eight great-grandparents defined ancestry of participants. Severity of carditis was classified according to the 2012 World Heart Federation guideline for the echocardiographic diagnosis of RHD. The IL-6 promoter rs1800797, IL1RN rs447713 and CTLA4 rs3087243 SNPs were genotyped by Taqman. Correlations were assessed by logistic regression analysis adjusting for gender and ancestry. RESULTS The IL-6 rs1800797 variant was significantly associated with RHD with carriers of the GG genotype 6.09 (CI 1.23; 30.23) times more likely to develop RHD than the carriers of the AA genotype (P=0.027). No significant associations with RHD were found for the IL1RN rs447713 and CTLA4 rs3087243 SNPs. Patients carrying the G allele (GG plus AG genotype) for the IL1RN rs447713 SNP had 2.36 times (CI 1.00; 5.56) more severe carditis than those without this allele (the AA genotype) (P=0.049). CONCLUSION The IL-6 promoter rs1800797 (-597G/A) SNP may influence susceptibility to RHD of people of Māori and Pacific ancestry living in NZ. The IL1RN rs447713 SNP may influence the severity of carditis in this population.

Abstract
Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

Abstract
BACKGROUND Rheumatic heart disease remains an important cause of acquired heart disease in developing countries. Although prevention of rheumatic fever and management of recurrences have been well established, optimal management of active rheumatic carditis remains unclear. This is an update of a review published in 2003, and previously updated in 2009 and 2012. OBJECTIVES To assess the effects, both harmful and beneficial, of anti-inflammatory agents such as aspirin, corticosteroids and other drugs in preventing or reducing further valvular damage in patients with acute rheumatic fever. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (2013, Issue 9 of 12), MEDLINE (Ovid, 1948 to 2013 October Week 1), EMBASE (Ovid, 1980 to 2013 Week 41) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 17 October 2013). We last searched Index Medicus (1950 to April 2001) in 2001. We checked reference lists of identified studies and applied no language restrictions. SELECTION CRITERIA Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins, pentoxifylline) versus placebo or controls, or comparing any of the anti-inflammatory agents versus one another, in adults and children with acute rheumatic fever diagnosed according to Jones, or modified Jones, criteria. The presence of cardiac disease one year after treatment was the major outcome criterion selected. DATA COLLECTION AND ANALYSIS Two review authors extracted data and assessed risk of bias using the methodology outlined in the Cochrane Handbook of Systematic Reviews of Interventions. Standard methodological procedures as expected by The Cochrane Collaboration were used. MAIN RESULTS No new studies were included in this update. Eight randomised controlled trials involving 996 people were selected for inclusion in the review. Researchers compared several steroidal agents such as corticotrophin, cortisone, hydrocortisone, dexamethasone, prednisone and intravenous immunoglobulin versus aspirin, placebo or no treatment. Six trials were conducted between 1950 and 1965; one was done in 1990 and the final study was published in 2001. Overall there were no observed significant differences in risk of cardiac disease at one year between corticosteroid-treated and aspirin-treated groups (six studies, 907 participants, risk ratio 0.87, 95% confidence interval 0.66 to 1.15). Similarly, use of prednisone (two studies, 212 participants, risk ratio 1.13, 95% confidence interval 0.52 to 2.45) compared with aspirin did not reduce the risk of heart disease after one year. Investigators in five studies did not report adverse events. The three studies reporting on adverse events reported substantial adverse events. However, all results should be interpreted with caution because of the age of the studies and the substantial risk of bias. AUTHORS' CONCLUSIONS Little evidence of benefit was found when corticosteroids or intravenous immunoglobulins were used to reduce the risk of heart valve lesions in patients with acute rheumatic fever. The antiquity of most of the trials restricted adequate statistical analysis of the data and acceptable assessment of clinical outcomes by current standards. In addition, risk of bias was substantial, so results should be viewed with caution. New randomised controlled trials in patients with acute rheumatic fever are warranted to assess the effects of corticosteroids such as oral prednisone and intravenous methylprednisolone and the effects of other new anti-inflammatory agents. Advances in echocardiography will allow more objective and precise assessments of cardiac outcomes.

Abstract
Recent advances in Kawasaki disease have included attempts to define genes involved in its pathogenesis. There have been recent advances in the studies of rheumatic carditis, leading to a better understanding of the mechanism of the disease. Histologic evaluation of patients with neonatal lupus erythematosus has revealed fibrosis with collagen deposition and calcification of the atrioventricular node. Therapy for cardiac involvement in systemic juvenile idiopathic arthritis should involve treatment of the underlying disease and systemic inflammatory state, and typically includes nonsteroidal antiinflammatory drugs, corticosteroids, disease-modifying drugs, and biologic therapies targeting tumor necrosis factor-alpha, interleukin-1, and interleukin-6.

Abstract
Registers of those with rheumatic heart disease or a history of acute rheumatic fever (RF) are key to prevent RF recurrences and improve disease control. Randomized controlled trials show intramuscular long-acting benzathine penicillin G is more effective than oral penicillin to prevent recurrences. Although some guidelines recommend three-weekly benzathine penicillin, four weekly is effective if compliance rates are high. Four-weekly penicillin delivery is also preferable to three-weekly regimens for health resource and logistical reasons and for patient acceptability and compliance.

Abstract
Background In Australia, rheumatic heart disease (RHD) is almost exclusively restricted to Aboriginal Australian and Torres Strait Islander people with children being at highest risk. International criteria for echocardiographic diagnosis of RHD have been developed but the significance of minor heart valve abnormalities which do not reach these criteria remains unclear. The Rheumatic Fever Follow-Up Study (RhFFUS) aims to clarify this question in children and adolescents at high risk of RHD. Methods/design RhFFUS is a cohort study of Aboriginal and/or Torres Strait Islander children and adolescents aged 8–17 years residing in 32 remote Australian communities. Cases are people with non-specific heart valve abnormalities detected on prior screening echocardiography. Controls (two per case) are age, gender, community and ethnicity-matched to cases and had a prior normal screening echocardiogram. Participants will have echocardiography about 3 years after initial screening echocardiogram and enhanced surveillance for any history suggestive of acute rheumatic fever (ARF). It will then be determined if cases are at higher risk of (1) ARF or (2) developing progressive echocardiography-detected valve changes consistent with RHD. The occurrence and timing of episodes of ARF will be assessed retrospectively for 5 years from the time of the RhFFUS echocardiogram. Episodes of ARF will be identified through regional surveillance and notification databases, carer/subject interviews, primary healthcare history reviews, and hospital separation diagnoses. Progression of valvular abnormalities will be assessed prospectively using transthoracic echocardiography and standardized operating and reporting procedures. Progression of valve lesions will be determined by specialist cardiologist readers who will assess the initial screening and subsequent RhFFUS screening echocardiogram for each participant. The readers will be blinded to the initial assessment and temporal order of the two echocardiograms. Discussion RhFFUS will determine if subtle changes on echocardiography represent the earliest changes of RHD or mere variations of normal heart anatomy. In turn it will inform criteria to be used in determining whether secondary antibiotic prophylaxis should be utilized in individuals with no clear history of ARF and minor abnormalities on echocardiography. RhFFUS will also inform the ongoing debate regarding the potential role of screening echocardiography for the detection of RHD in this setting.

Abstract
Rheumatic heart disease, often neglected by media and policy makers, is a major burden in developing countries where it causes most of the cardiovascular morbidity and mortality in young people, leading to about 250,000 deaths per year worldwide. The disease results from an abnormal autoimmune response to a group A streptococcal infection in a genetically susceptible host. Acute rheumatic fever--the precursor to rheumatic heart disease--can affect different organs and lead to irreversible valve damage and heart failure. Although penicillin is effective in the prevention of the disease, treatment of advanced stages uses up a vast amount of resources, which makes disease management especially challenging in emerging nations. Guidelines have therefore emphasised antibiotic prophylaxis against recurrent episodes of acute rheumatic fever, which seems feasible and cost effective. Early detection and targeted treatment might be possible if populations at risk for rheumatic heart disease in endemic areas are screened. In this setting, active surveillance with echocardiography-based screening might become very important.

Abstract
Sydenham chorea is a post-streptococcal, autoimmune, neuropsychiatric, movement disorder. There is no effective treatment. In a randomized study, comparison was made of the outcomes of 10 children treated with standard management alone compared to 10 who received additional intravenous immunoglobulin. The outcomes were assessed using a clinical rating scale, brain single-photon emission computed tomography, and the duration of symptomatic treatment. All three outcome measurement tools found improved outcomes in the group that received intravenous immunoglobulin.

Abstract
Intravenous immunoglobulins (IVIg) were first introduced in the middle of the twentieth century for the treatment of primary immunodeficiencies. In 1981, Paul Imbach noticed an improvement of immune-mediated thrombocytopenia, in patients receiving IVIg for immunodeficiencies. This opened a new era for the treatment of autoimmune conditions with IVIg. Since then, IVIg has become an important treatment option in a wide spectrum of diseases, including autoimmune and acute inflammatory conditions, most of them off-label (not included in the US Food and Drug Administration recommendation). A panel of immunologists and internists with experience in IVIg therapy reviewed the medical literature for published data concerning treatment with IVIg. The quality of evidence was assessed, and a summary of the available relevant literature in each disease was given. To our knowledge, this is the first all-inclusive comprehensive review, developed to assist the clinician when considering the use of IVIg in autoimmune diseases, immune deficiencies, and other conditions.

Abstract
Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

Abstract
OBJECTIVE Subclinical carditis (SCC)--pathological valvular regurgitation detected on echocardiography that is not evident clinically--has been reported in acute rheumatic fever (ARF), but its significance is unknown. We aimed to review the existing literature on the prevalence and outcome of SCC in ARF. METHODS We conducted a systematic literature review using MEDLINE. RESULTS Prevalences of SCC in ARF ranged from 0% (in one study only) to 53% in 23 articles. The weighted pooled prevalence of SCC in ARF was 16.8% (95%CI 11.9 to 21.6). This increased slightly to 18.1% (95%CI 11.1 to 25.2) by analysing only the 10 studies that applied full World Health Organization criteria for SCC diagnosis. The weighted pooled prevalence of persistence or deterioration of SCC 3 to 23 months after ARF diagnosis was 44.7% (95%CI 19.3 to 70.2) from 11 articles. CONCLUSION SCC is relatively common in ARF. Although some studies suggest that SCC lesions may persist or deteriorate, the available data are insufficient and of poor quality, so no confident conclusions can be drawn about the prognosis of SCC. Until better studies are conducted, clinicians will have to make management decisions that are not evidence-based. These decisions will have important practical implications for the use of echocardiography acutely and during follow-up, diagnosis of ARF, and duration of secondary prophylaxis in patients with SCC.

Abstract
Acute rheumatic fever (ARF) is an inflammatory disease of the heart, joints, CNS, and subcutaneous tissue that develops after a pharyngeal infection by one of the group A beta-hemolytic streptococci (Streptococcus pyogenes). The pathogenesis of the disease remains an enigma and specific treatment is not available, yet prevention of initial and recurrent attacks is possible by penicillin treatment. Rheumatic fever is especially important because of the heart disease that usually ensues; as succinctly stated by Lasegue many years ago, rheumatic fever "licks the joints and bites the heart", a statement that holds true today. Rheumatic fever is no longer a significant health problem in most socioeconomically advanced countries but it still causes 25-40% of all cardiovascular disease in the world, including tropical countries where it was once believed to be rare. In many countries it causes more hospital admissions than congenital heart conditions.ARF and rheumatic heart disease - with high associated morbidity, cost, and mortality - are largely preventable. Importantly, recurrences of rheumatic fever with their increased likelihood of more severe carditis are inexpensively preventable. Primary prevention has been achieved innovatively in some countries, for example, Costa Rica, and more conventionally in some developed countries. Treatment of the acute episode controls symptoms and may limit cardiac damage.

Abstract
Acute rheumatic fever (ARF) and its chronic sequela, rheumatic heart disease (RHD), have become rare in most affluent populations, but remain unchecked in developing countries and in some poor, mainly indigenous populations in wealthy countries. More than a century of research, mainly in North America and Europe, has improved our understanding of ARF and RHD. However, whether traditional views need to be updated in view of the epidemiological shift of the past 50 years is still to be established, and improved data from developing countries are needed. Doctors who work in populations with a high incidence of ARF are adapting existing diagnostic guidelines to increase their sensitivity. Group A streptococcal vaccines are still years away from being available and, even if the obstacles of serotype coverage and safety can be overcome, their cost could make them inaccessible to the populations that need them most. New approaches to primary prevention are needed given the limitations of primary prophylaxis as a population-based strategy. The most effective approach for control of ARF and RHD is secondary prophylaxis, which is best delivered as part of a coordinated control programme.

Abstract
Betahemolytic strains of streptococcus A are able to induce a spectrum of immunologically induced diseases, depending on the immunogenic M structure of the bacteria as well as on the genetic determined reaction of the host. In acute rheumatic fever (ARF) the Jones criteria, revised and modified several times and updated in 1992, remain the diagnostic standard. Echocardiography, still not included in the Jones criteria, has become a very important diagnostic tool, especially as half of the ARF induced carditis cases are clinically inapparent. Diagnosis may be very difficult if arthritis is the only major sign, especially if not occurring in the typical migrating pattern, a fact frequently reported from countries with a high risk of ARF. Poststreptococcal reactive arthritis (PSRA) has been described as a different entity as well as a part of rheumatic fever. There is a lack of validated diagnostic criteria to establish a reliable diagnosis. There are no accepted recommendations for antibiotic prophylaxis in PSRA.

Abstract
BACKGROUND Estimates of excess risk of valvular heart disease among prior users of fenfluramine and dexfenfluramine have varied widely. Two major forms of bias appear to contribute to this variability and also result in a systematic under-estimation of risk. The first, a form of nondifferential misclassification, is the result of including background, prevalent cases among both exposed and unexposed persons in calculations of risk. The second bias results from not considering the relatively short duration of exposure to drugs. METHODS We examined data from all available echocardiographic studies reporting the prevalence of aortic regurgitation (AR) and mitral regurgitation (MR) among persons exposed to fenfluramine or dexfenfluramine and a suitable control group. We also included one study in which previously existing AR or MR had been excluded. We corrected for background prevalent cases, estimated incidence rates in unexposed persons, and performed a person-years analysis of apparent incidence rates based on exposure time to provide an unbiased estimate of relative risk. RESULTS Appearance of new AR was strongly related to duration of exposure (R2 = 0.75, p < 0.0001). The summary relative risk for mild or greater AR was 19.6 (95% CI 16.3-23.5, p < 0.00001); for moderate or greater MR it was 5.9 (95% CI 4.0-8.6, p < 0.00001). CONCLUSION These findings provide strong support for the view that fenfluramine and dexfenfluramine are potent causal factors in the development of both aortic and mitral valvular heart disease.

Abstract
Enormous advances in the diagnosis and management of heart disease in pediatric patient have taken place during the last-four decades. In this review the authors will concentrate on the developments within the last five to ten years. It will deal with what may be called medical advances. Recent advances in molecular genetics and defining the familial patterns have led to finding that certain genetic and molecular factors are linked to congenital heart disease and arrythmia, thus providing opportunity for improved genetic counseling and future gene therapy. Medical treatment of congenital heart disease targets not only the augmentation of ventricular contractility (positive inotropy) but also addresses the neuro-humoral derangement associated with it. The ultrasound technology for the evaluation of the heart has come a long way from the early A-mode and M-mode capabilities to color Doppler, 2-dimentional and 3-dimentional capabilities.

Abstract
BACKGROUND Rheumatic heart disease remains the most important cause of acquired heart disease in developing countries. Although the prevention of rheumatic fever and the management of recurrences is well established the optimal management of active rheumatic carditis is still unclear. OBJECTIVES To assess the effects of anti-inflammatory agents such as aspirin, corticosteroids and immunoglobulin for preventing or reducing further heart valve damage in patients with acute rheumatic fever. SEARCH STRATEGY We searched the Cochrane Controlled Trials Register (Issue 4, 2000), MEDLINE (1966 to April 2002), EMBASE (1998 to November 2002), LILACS (1998 to November 2002), Index Medicus (1950 to December 2000) and references lists of identified studies. SELECTION CRITERIA Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins) with placebo or controls, or comparing any of the anti-inflammatory agents with one another, in patients with acute rheumatic fever diagnosed according to the Jones, or modified Jones criteria. The presence of cardiac disease one year after treatment was the major outcome criteria selected. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed trial quality. MAIN RESULTS Eight randomised controlled trials involving 996 people were included. Several steroidal agents viz. ACTH, cortisone, hydrocortisone, dexamethasone and prednisone, and intravenous immunoglobulin were compared to aspirin, placebo or no treatment in the various studies. Six of the trials were conducted between 1950 and 1965, whilst the remaining two were done in the last 10 years. Overall there was no significant difference in the risk of cardiac disease at one year between the corticosteroid-treated and aspirin-treated groups (relative risk 0.87, 95% confidence interval 0.66 to 1.15). Similarly use of prednisone (relative risk 1.78, 95% confidence interval 0.98 to 3.34) or intravenous immunoglobulins (relative risk 0.87, 95%confidence interval 0.55 to 1.39) when compared to placebo did not reduce the risk of developing heart valve lesions at one year. REVIEWER'S CONCLUSIONS There is no benefit in using corticosteroids or intravenous immunoglobulins to reduce the risk of heart valve lesions in patients with acute rheumatic fever. The antiquity of most of the trials restricted adequate statistical analysis of the data and acceptable assessment of clinical outcomes by current standards. New randomised controlled trials in patients with acute rheumatic fever to assess the effects of corticosteroids such as oral prednisone and intravenous methylprednisone, and other new anti-inflammatory agents are warranted. Advances in echocardiography will allow for more objective and precise assessment of cardiac outcomes.

Abstract
Rheumatic fever and rheumatic heart disease continue unabated, affecting young individuals in most of the developing nations. Focal outbreaks of smaller magnitude have also been reported since the mid-1980s from industrialized western nations, where this disease had almost disappeared. The introduction of penicillin in the mid-1940s has markedly changed the natural history of rheumatic fever, although the incidence of rheumatic fever declined in developed nations even before that, mainly due to better living conditions. Treatment of rheumatic fever chiefly involves the use of antibiotics (penicillin) and anti-inflammatory drugs, like salicylates or corticosteroids, to eradicate Streptococci. Patients with severe carditis, congestive heart failure, or pericarditis are best treated with corticosteroids because these are more potent anti-inflammatory agents than salicylates. Salicylates may be sufficient for cases with mild or no carditis. The treatment must be continued for 12 weeks. Several studies have shown that valvular regurgitation, and not myocarditis, is the cause of congestive heart failure in active rheumatic carditis. Therefore, surgery with mitral valve replacement or repair is indicated in cases with intractable hemodynamics due to mitral regurgitation. The development of chronic valvular lesion after an episode of rheumatic fever is dependent upon the presence or absence of carditis in the previous attack and compliance with secondary prophylaxis. Recurrences due to inadequate penicillin prophylaxis are responsible for hemodynamically significant chronic valvular lesions requiring surgery. Primary prevention of rheumatic fever is fraught with difficulties and may not be feasible in most of the countries where the disease is rampant. Secondary prevention, ie, preventing recurrence of rheumatic fever, is the appropriate strategy with proven efficacy. A repository form of penicillin, benzathine penicillin G, given as an intramuscular injection at 3 weekly intervals in the dose of 1,200,000 U, remains the treatment of choice for secondary prevention of rheumatic fever. Alternative antibiotics may be used in those allergic to penicillin. An effective and safe vaccine against rheumatic fever is not yet available.
