Clinical, laboratory and echocardiographic profile of acute rheumatic fever in Nepali children

How accurate is the diagnosis of rheumatic fever in Egypt? Data from the national rheumatic heart disease prevention and control program (2006-2018)

Rheumatic heart disease (RHD) as a chronic sequela of repeated episodes of acute rheumatic fever (ARF), remains a cause of cardiac morbidity in Egypt although it is given full attention through a national RHD prevention and control program. The present report reviews our experience with subjects presenting with ARF or its sequelae in a single RHD centre and describes the disease pattern over the last decade. A cross-sectional study was conducted in El-Mahalla RHD centre between 2006 and 2018. A total of 17014 individual were enrolled and evaluated. Diagnosis ARF was based on the 2015 revised Jones criteria and RHD was ruled in by echocardiography. The majority of the screened subjects were female (63.2%), in the age group 5-15 years (64.6%), rural residents (61.2%), had primary education (43.0%), and of low socioeconomic standard (50.2%). The total percentage of cases presenting with ARF sequelae was 29.3% [carditis/RHD (10.8%), rheumatic arthritis (Rh.A) (14.9%), and Sydenham's chorea (0.05%)]. Noticeably, 72% were free of any cardiac insult, of which 37.7% were victims of misdiagnoses made elsewhere by untrained practitioners who prescribed for them long term injectable long-acting penicillin [Benzathine Penicillin G (BPG)] without need. About 54% of the study cohort reported the occurrence of recurrent attacks of tonsillitis of which 65.2% underwent tonsillectomy. Among those who experienced tonsillectomy and/or received BPG in the past, 14.5% and 22.3% respectively had eventually developed RHD. Screening of family members of some RHD cases who needed cardiac surgery revealed 20.7% with undiagnosed ARF sequalae [RHD (56.0%) and Rh.A (52.2%)]. Upon the follow-up of RHD cases, 1.2% had improved, 98.4% were stable and 0.4% had their heart condition deteriorated. Misdiagnosis of ARF or its sequelae and poor compliance with BPG use may affect efforts being exerted to curtail the disease. Updating national guidelines, capacity building, and reliance on appropriate investigations should be emphasized. Since the genetic basis of RHD is literally confirmed, a family history of RHD warrants screening of all family members for early detection of the disease.

Clinical Profile and Management of Rheumatic Heart Disease in Children and Young Adults at a Tertiary Cardiac Center in Indonesia

Introduction: Rheumatic heart disease (RHD) remains a major public health issue affecting children and young adults in developing countries. This study aimed to evaluate the clinical characteristics, management, and reactivation of RHD among children and young adults.

Patients and Methods: This was a hospital-based retrospective study conducted at the National Cardiovascular Center Harapan Kita, Indonesia; we retrieved relevant data from patients diagnosed with RHD between 2012 and 2018.

Results: Two hundred and seventy-nine patients were diagnosed with rheumatic heart disease, of whom 108 were children (mean age of 12.02 ± 3.36 years) and 171 were young adults (mean age was 24.9 ± 3.84). RHD was more common in female than in male young adults (1.5:1). Hospitalization due to RHD complications such as congestive heart failure was seen in 11.11% of cases in children, while pulmonary hypertension was present in 19.95% young adult cases. Reactivation of RHD occurred in 17.2% (48/279) cases, significantly in children (p < 0.001). Overall, the mitral valve (either isolated or combined) was the organ most affected in children (39.13%) and young adults (44.81%). Isolated mitral regurgitation was more common in children (13/21, 61.9%), while isolated mitral stenosis was more common in young adults (19/47, 40.42%). There was a high rate of rheumatic tricuspid valve disease in all populations (193/279, 69.17%) and reported involvement of pulmonary regurgitation (46/279, 16.48%). Multivalve lesions were more common than single lesions in both groups, with a combination of mitral and tricuspid regurgitation the predominant type in children (32/43, 74.41%) and mixed mitral lesion and tricuspid regurgitation in young adults (22/72, 30.56%). We observed a significant occurrence of quadrivalve lesions in children (p = 0.039). Valve repair was more common in children (49.07%) and replacement in young adults (32.16%), with low in-hospital mortality. Compliance with secondary prophylaxis was a significant challenge.

Conclusion: Chronic RHD often presented with complications of the disease or reactivation of rheumatic fever (RF). Inadequate treatment of RF/RHD leads to extensive valvular damage and consequent disabilities. Efforts toward active early diagnosis and prompt treatment of RF/RHD and effective preventive measures are essential.

Acute rheumatic fever in south-east of Turkey: clinical features and epidemiological evaluation of the patients over the last 25 years

This study evaluates clinical and epidemiological features of acute rheumatic fever using the data of last 25 years in our hospital in south-east of Turkey. The medical records of 377 patients with acute rheumatic fever admitted to Pediatric Cardiology Department of Çukurova University during 1993-2017 were retrospectively analysed. Two hundred and six patients were admitted between 1993 and 2000, 91 between 2001 and 2008, and 80 between 2009 and 2017. The largest age group (52%) were between 9 to 12 years of age and approximately two-thirds of the patients presented in the spring and winter seasons (62.8%). Among the major findings, the most common included carditis 83.6% (n = 315), arthritis at 74% (n = 279), Sydenham's chorea at 13.5% (n = 51), and only two patients (0.5%) had erythema marginatum and two patients (0.5%) had subcutaneous nodule. Carditis was the most common manifestation observed in 315 patients (83.6%). The most commonly affected valve was the mitral valve alone (54.9%), followed by a combined mitral and aortic valves (34%) and aortic valve alone (5.7%). Of the patients with carditis, 48.6% (n = 153) had mild carditis, of which 45 had a subclinical. Sixty-two patients (19.7%) had moderate and 100 patients (31.7%) had severe carditis. At the follow-up, 2 patients died and 16 patients underwent valve surgery. Twenty-eight (7.4%) patients' valve lesions were completely resolved. Conclusion: Although the incidence of acute rheumatic fever decreased, it still is an important disease that can cause serious increases in morbidity and mortality rates in our country.

Acute rheumatic fever diagnosis and management: Review of the global implications of the new revised diagnostic criteria with a focus on Saudi Arabia

Rheumatic fever (RF) is a common cause of acquired heart disease in children worldwide. It is a delayed, nonsuppurative, autoimmune phenomenon following pharyngitis, impetigo, or scarlet fever caused by group A β-hemolytic streptococcal (GAS) infection. RF diagnosis is clinical and based on revised Jones criteria. The first version of the criteria was developed by T. Duckett Jones in 1944, then subsequently revised by the American Heart Association (AHA) in 1992 and 2015. However, RF remains a diagnostic challenge for clinicians because of the lack of specific clinical or laboratory findings. As a result, it has been difficult for some time to maintain a balance between over- and underdiagnosis of RF cases. The Jones criteria were revised in 2015 by the AHA, and the main modifications were as follows: the population was subdivided into moderate- to high-risk and low risk; the concept of subclinical carditis was introduced; and monoarthritis was included as a feature of musculoskeletal inflammation in the moderate- to high-risk population. This review will highlight the major changes in the AHA 2015 revised Jones criteria for pediatricians and general practitioners.

Paediatric acute rheumatic fever in developed countries: Neglected or negligible disease? Results from an observational study in Lombardy (Italy)

Introduction

Acute Rheumatic Fever (ARF) is a multisystemic disease that results from an autoimmune reaction due to group A streptococcal infection. The disease affects predominantly children aged 5 to 15 years and although its incidence in developed Countries declined since the early 1900s, to date there is a paucity of data that confirm this epidemiological trend.

Objective

The study aimed to assess the burden of ARF in term of hospitalization and to describe the characteristics of acute rheumatic fever (ARF) in the paediatric population of Lombardy.

Study design

The study was carried out by analyzing hospital discharge records of patients resident of Lombardy and aged 0–17 years old who, from 2014 to 2016, were hospitalized with the diagnosis of ARF. The following variables have been studied: age, sex, municipality of residence, date of diagnosis of each patient, hospital of admission, and presentation of the disease.

Results

From 2014 to 2016, 215 patients were found to meet the inclusion criteria and diagnosed as affected from Acute Rheumatic Fever. The rate of hospitalization showed a slightly increasing trend from 3.42 in 2014 to about 5.0 in 2016. Moreover, ARF presented a typical seasonal trend with lower cases in the autumn and a peak of hospitalization in the spring.

Conclusion

To date, ARF seems to be a rare but not negligible disease in southern central European countries, and in Lombardy we estimated an annual hospitalization rate of 4.24 cases per 100,000 children. The increasing trend found in our study suggests that the burden of the disease could be reduced by involving multidisciplinary health professionals who, in addition to the paediatrician of free choice, would promote evidence based medicine management of the disease during all its clinical phases.

Systematic Literature Review on the Incidence and Prevalence of Heart Failure in Children and Adolescents

While the epidemiology of adult heart failure has been extensively researched, this systematic review addresses the less well characterized incidence and prevalence of pediatric HF. The search strategy used Cochrane methodology and identified 83 unique studies for inclusion. Studies were categorized according to whether the HF diagnosis was reported as primary (n = 10); associated with other cardiovascular diseases (CVDs) (n = 49); or associated with non-CVDs (n = 24). A narrative synthesis of the evidence is presented. For primary HF, the incidence ranged from 0.87/100,000 (UK and Ireland) to 7.4/100,000 (Taiwan). A prevalence of 83.3/100,000 was reported in one large population-based study from Spain. HF etiology varied across regions with lower respiratory tract infections and severe anemia predominating in lower income countries, and cardiomyopathies and congenital heart disease major causes in higher income countries. Key findings for the other categories included a prevalence of HF associated with cardiomyopathies ranging from 36.1% (Japan) to 79% (US); associated with congenital heart disease from 8% (Norway) to 82.2% (Nigeria); associated with rheumatic heart diseases from 1.5% (Turkey) to 74% (Zimbabwe); associated with renal disorders from 3.8% (India) to 24.1% (Nigeria); and associated with HIV from 1% (US) to 29.3% (Brazil). To our knowledge, this is the first systematic review of the topic and strengthens current knowledge of pediatric HF epidemiology. Although a large body of research was identified, heterogeneity in study design and diagnostic criteria limited the ability to compare regional data. Standardized definitions of pediatric HF are required to facilitate cross-regional comparisons of epidemiological data.

Evaluation of the American Heart Association 2015 revised Jones criteria versus existing guidelines

OBJECTIVES

To compare the diagnostic yield of acute rheumatic fever (ARF) by the American Heart Association/ American College of Cardiology (AHA/ACC) 2015 revised Jones criteria with the WHO 2004 and Australian guidelines 2012.

METHODS

Retrospective observational study in 93 cases of suspected ARF admitted to the Division of Paediatric Cardiology between January 2012 and December 2014. WHO 2004, Australian guidelines and AHA/ACC 2015 Jones criteria were applied to assess definite and probable ARF.

RESULTS

Of the 93 cases, 50 were diagnosed as the first episode of ARF and 43 as a recurrence of the condition. Subclinical carditis was a predominant presentation (38%) in the first episode group (p<0.01) whereas in the recurrence group carditis (88%) was the main presentation (p<0.01). Among the joint manifestations, the majority of patients in both the first episode group and the recurrence group presented with arthralgia. Of all the patients with suspected ARF (50), 34% of cases did not fulfil the standard Jones criteria 2004; however, 86% qualified as having ARF on applying the Australian and AHA/ACC 2015 criteria. Surprisingly in the recurrence group only 67% of the patients fulfilled AHA/ACC 2015 despite the modifications incorporated beyond WHO 2004; however, all the patients fulfilled the Australian guidelines either as definite (88.4%) or probable (11.6%). Inclusion of subclinical carditis, polyarthralgia and monoarthritis as major criteria influenced the diagnosis to definite ARF in 20%, 10% and 4% of patients, respectively.

CONCLUSIONS

The clinical manifestations of ARF, comprising subclinical carditis and arthralgia, are possibly milder in the Indian population; hence, inclusion of subclinical carditis, polyarthralgia and monoarthritis as major criteria in the newer guidelines has improved the diagnostic yield of ARF. In the absence of a gold standard for the diagnosis of ARF, it is not possible to comment on sensitivity and specificity.

Revision of the Jones Criteria for the diagnosis of acute rheumatic fever in the era of Doppler echocardiography: a scientific statement from the American Heart Association

BACKGROUND

Acute rheumatic fever remains a serious healthcare concern for the majority of the world's population despite its decline in incidence in Europe and North America. The goal of this statement was to review the historic Jones criteria used to diagnose acute rheumatic fever in the context of the current epidemiology of the disease and to update those criteria to also take into account recent evidence supporting the use of Doppler echocardiography in the diagnosis of carditis as a major manifestation of acute rheumatic fever.

METHODS AND RESULTS

To achieve this goal, the American Heart Association's Council on Cardiovascular Disease in the Young and its Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee organized a writing group to comprehensively review and evaluate the impact of population-specific differences in acute rheumatic fever presentation and changes in presentation that can result from the now worldwide availability of nonsteroidal anti-inflammatory drugs. In addition, a methodological assessment of the numerous published studies that support the use of Doppler echocardiography as a means to diagnose cardiac involvement in acute rheumatic fever, even when overt clinical findings are not apparent, was undertaken to determine the evidence basis for defining subclinical carditis and including it as a major criterion of the Jones criteria. This effort has resulted in the first substantial revision to the Jones criteria by the American Heart Association since 1992 and the first application of the Classification of Recommendations and Levels of Evidence categories developed by the American College of Cardiology/American Heart Association to the Jones criteria.

CONCLUSIONS

This revision of the Jones criteria now brings them into closer alignment with other international guidelines for the diagnosis of acute rheumatic fever by defining high-risk populations, recognizing variability in clinical presentation in these high-risk populations, and including Doppler echocardiography as a tool to diagnose cardiac involvement.

Evaluation of the policy of secondary prevention against rheumatic fever among Egyptian children

OBJECTIVE

We evaluated the effectiveness of long acting penicillin (LAP) as a 2-weekly regimen in winter and a 3-weekly regimen in summer for prevention of streptococcal colonization and also studied the common complaints of patients during the period of compliance for LAP administration. We also attempted to determine the incidence of relapses or recurrence of rheumatic fever (RF) after the onset of first episode of RF.

PATIENTS & METHODS

210 rheumatic patients with good compliance to LAP (for at least one year) were included in the study. Demographic, clinical information, patients' complaints and echocardiographic data of rheumatic patients were collected both retrospectively and prospectively. Anti-streptolysin O titre (ASOT) and throat swab culture were done at the end of the study (on Day 14 in the 2-weekly regimen and on Day 21 in the 3-weekly regimen).

RESULTS

The age of onset of rheumatic fever was mostly between 5 and 15 years and the youngest patient was 2 years old. Subclinical carditis (SCC) was present in 79 (37%) of all the patients in the study population. Only 7 patients (3.3%) had a relapse within 2 years of the acute episode of RF. At the end of the study, ASOT was found to be high only in 11 patients (5.2%) and throat swab cultures were found negative in all patients

CONCLUSION

LAP regimen is fairly effective in eradicating streptococcal colonization. The incidence of relapse of RF within 2 years of the acute episode of RF is relatively low.

Clinical spectrum of rheumatic Fever and rheumatic heart disease: a 10 year experience in an urban area of South India

Background:

Rheumatic fever (RF) is an important problem concerning developing countries like India. Rheumatic heart disease (RHD) is one of the most readily preventable chronic diseases.

Aim:

This study was done to find out the clinical profile, risk factors, compliance with treatment and outcome among RF/RHD cases so as to suggest better case management strategies.

Materials and Methods:

Clinical records of 51 RF and 71 RHD cases admitted in tertiary care hospitals in Mangalore between 2001 and 2010 were reviewed retrospectively.

Results:

Mean age of RF cases were 17.4 ± 12.1 years and RHD cases were 33.2 ± 18.6 years. More than half of RF and RHD cases were males. Commonest risk factors among RF cases were poor socioeconomic status (60.4%), history of upper respiratory tract infection before disease onset (58.8%) and undernutrition (35.3%). Commonest clinical manifestation among RF cases was fever 39 (76.5%) followed by polyarthritis 34 (66.7%). Commonest valvular lesions among RHD cases was mitral stenosis with mitral regurgitation found in 42.9% cases. Compliance of patients with prophylactic antibiotics was found to be 37 (30.3%). Mortality rate was significantly more among RHD cases (P = 0.0399).

Conclusions:

Improvement of socioeconomic and nutritional factors is an important task required for primary prophylaxis and of compliance for secondary prophylaxis of RF.

The heart and pediatric rheumatology

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.

The worldwide epidemiology of acute rheumatic fever and rheumatic heart disease

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are significant public health concerns around the world. Despite decreasing incidence, there is still a significant disease burden, especially in developing nations. This review provides background on the history of ARF, its pathology and treatment, and the current reported worldwide incidence of ARF and prevalence of RHD.

Asymptomatic rhythm and conduction abnormalities in children with acute rheumatic fever: 24-hour electrocardiography study

Some rhythm and conduction abnormalities can occur in children with acute rheumatic fever. These abnormalities have been defined based on standard electrocardiography; however, the real prevalence of these abnormalities has not been investigated previously by the evaluation of long-term electrocardiographic recordings. In this study, we evaluated the asymptomatic rhythm and conduction abnormalities in children with acute rheumatic fever by evaluating the 24-hour electrocardiography. We evaluated the standard electrocardiography and the 24-hour electrocardiography of 64 children with acute rheumatic fever. On standard electrocardiography, the frequency of the first-degree atrioventricular block was found to be 21.9%. Electrocardiography at 24 hours detected three additional and separate patients with a long PR interval. Mobitz type I block and atypical Wenckebach periodicity were determined in one patient (1.56%) on 24-hour electrocardiography. While accelerated junctional rhythm was detected in three patients on standard electrocardiography, it was present in nine patients according to 24-hour electrocardiography. Premature contractions were present in 1.7% of standard electrocardiography, but in 29.7% of 24-hour electrocardiography. Absence of carditis was found to be related to the presence of accelerated junctional rhythm (p > 0.05), and the presence of carditis was found to be related to the presence of premature contractions (p = 0.000). In conclusion, our results suggest that in children with acute rheumatic fever, the prevalence of rhythm and conduction abnormalities may be much higher than determined on standard electrocardiography. Further studies are needed to clarify whether or not these abnormalities are specific to acute rheumatic fever.
