RESUMO
OBJECTIVE: To understand the burden of acute rheumatic fever (ARF) among children living in low-income countries who present to the hospital with febrile illness and to determine the role of handheld echocardiography (HHE) in uncovering subclinical carditis as a major manifestation of ARF. STUDY DESIGN: This was a cross-sectional study carried at the Pediatric Hospital in Al Obeid, North Kordofan, Sudan, from September 2022 to January 2023 and including febrile children 3 through 18 years of age with or without clinical features of ARF and without another cause for their fever (not excluding malaria). History, examination, blood investigations, and HHE were done. ARF was diagnosed according to the Jones criteria. Clinical ARF was diagnosed if there was a major clinical Jones criterion and silent ARF if the only major Jones criteria was subclinical carditis. RESULTS: The study cohort included 400 children with a mean age of 9 years. Clinical ARF was diagnosed in 95 patients (95/400, 24%), most of whom presented with a joint major manifestation (88/95, 93%). Among the 281 children who did not present with a clinical manifestation of ARF, HHE revealed rheumatic heart disease (RHD) in 44 patients (44/281, 16%); 31 of them fulfilled criteria for silent ARF (31/281, 11%). HHE increased the detection of ARF by 24%. HHE revealed mild RHD in 41 of 66 (62%) and moderate or severe RHD in 25 of 66 (38%) patients. Both sensitivity and specificity of HHE compared with standard echocardiography were 88%. CONCLUSIONS: There is a significant burden of ARF among febrile children in Sudan. HHE increased the sensitivity of diagnosis, with 11% of children having subclinical carditis as their only major manifestation (ie, silent ARF). RHD-prevention policies need to prioritize decentralization of echocardiography to improve ARF detection.

The spectrum of diseases caused by Streptococcus pyogenes (Strep A) ranges from superficial to serious life-threatening invasive infections. We conducted a scoping review of published articles between 1980 and 2021 to synthesize evidence of state transitions across the Strep A disease spectrum. We identified 175 articles reporting 262 distinct observations of Strep A disease state transitions. Among the included articles, the transition from an invasive or toxin-mediated disease state to another disease state (i.e., to recurrent ARF, RHD or death) was described 115 times (43.9% of all included transition pairs) while the transition to and from locally invasive category was the lowest (n = 7; 0.02%). Transitions from well to any other state was most frequently reported (49%) whereas a relatively higher number of studies (n = 71) reported transition from invasive disease to death. Transitions from any disease state to locally invasive, Strep A pharyngitis to invasive disease, and chronic kidney disease to death were lacking. Transitions related to severe invasive diseases were more frequently reported than superficial ones. Most evidence originated from high-income countries and there is a critical need for new studies in low- and middle-income countries to infer the state transitions across the Strep A disease spectrum in these high-burden settings.

The burden of group A streptococcus (GAS) infection and its rheumatic sequelae remains dramatically high, especially in low-income countries. Recently, an increased number of Acute Rheumatic Fever (ARF) cases was documented in many regions of Italy. The diagnosis of rheumatic sequelae relies on clinical signs and on the evaluation of the Antistreptolysin O titre (ASO), whose variations are globally reported. To re-examine the standard reference value of ASO titre, by measuring either its upper limit of normal (ULN) in a population of healthy children (HC) or comparing these values with streptococcal antibodies registered in a cohort of patients affected by the rheumatic sequelae of GAS infection. We performed a multicenter retrospective study. We enrolled 125 HC, aged 2-17 years, and a total of 181 patients affected by ARF, acute streptococcal pharyngitis, post-streptococcal arthritis, Henoch-Schönlein purpura and erythema nodosum, divided into four groups. The levels of ASO and anti-deoxyribonuclease B (anti-DNase B) titres were analyzed and compared among the various groups. Moreover, the 80th percentile value was calculated and established as the ULN for ASO titre in HC group. The ULN for ASO titre in overall HC group was 515 IU/mL, resulting in higher than used in the routine investigation. The ASO titre was significantly higher in patients with rheumatic sequelae compared with HC group, with a peak in the age between 5 and 15 years. Conclusion: Our study established a new ULN normal value of streptococcal serology in a childhood and adolescent population of Italy, suggesting the need to extend this revaluation to the critical areas, in order to avoid underestimating ARF diagnosis. The correct interpretation of ASO and anti-DNase B values in the context of rheumatic diseases has been discussed. What is Known: ⢠The global burden of disease caused by group A streptococcus is not known and remains an important cause of morbidity and mortality. Acute rheumatic fever continues to be a serious worldwide public health problem and a recent recurrence of group A streptococcus infection cases is observed. ⢠The streptococcal sequelae requires evidence of preceding streptococcal infection, commonly elevated streptococcal antibody titre, but the upper limit for these titres varies considerably based on age group, region, and origin. What is New: ⢠This study provides population-specific values for streptococcal antibody titres in Italy. ⢠Interpret the results of group A streptococcal antibody tests within the clinical context.

BACKGROUND: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major public health issues. Although the primary and secondary prevention of RHD through appropriate management of bacterial pharyngitis and ARF are well-described in the literature, few studies address the knowledge, attitude, and practice (KAP) of developing countries. We aimed to evaluate the KAP of the frontline physicians in Egyptian university hospitals regarding pharyngitis and ARF. METHODS: We employed a cross-sectional design between September 1st, 2022, and January 31st, 2023 using a self-administered questionnaire in 21 Egyptian universities. The questionnaire was developed based on previous studies and recent guidelines and included four domains: sociodemographic data, knowledge, attitude, and practice regarding pharyngitis and ARF. We utilized both online (Google Forms) and paper surveys. Frontline physicians, including interns, residents, and assistant lecturers, were conveniently invited to participate. Furthermore, with the help of participating phycisians in recruiting their colleagues, we utilized the snowball method. Data were analyzed using IBM SPSS version 27 software. RESULTS: The final analysis included 629 participants, of whom 372 (59.1%) were males and 257 (40.9%) had direct contact with ARF patients. Most participants (61.5%) had a fair knowledge level while 69.5% had a fair level of practice regarding ARF and pharyngitis. Higher satisfactory knowledge levels were noted regarding pharyngitis (17.1% vs. 11.3%; p-value: 0.036) and ARF (26.8% vs. 18%; p-value: 0.008) among physicians dealing directly with ARF cases compared to physicians in departments not dealing directly with ARF cases. Physicians in Cairo region universities had significantly higher levels of satisfactory knowledge about ARF compared to Delta and Upper Egypt region universities (p = 0.014). Delta region universities showed significantly lower levels of practice compared to Cairo and Upper Egypt region universities (p = 0.027). The most frequently recognized barriers against health promotion were low socioeconomic status (90.3%) and lack of adequate public education (85.8%). CONCLUSIONS: Despite the fair knowledge and practice levels towards bacterial pharyngitis and ARF among participants, many gaps were still identified that might contribute to RHD prevalence. Educational interventions should be implemented by updating the local guidelines in Egypt for diagnosis and management based on the most recent guidelines.

AIM: To describe the clinical profile of acute rheumatic fever (ARF) presentations to paediatric cardiology tertiary services in Western Australia (WA). METHODS: A retrospective clinical audit of individuals with confirmed ARF referred to the only paediatric tertiary cardiac service in WA (1 January 1987 to 31 December 2020). Comparisons between inpatient, outpatient, remote and non-remote groups were assessed. RESULTS: Four hundred seventy-one episodes of ARF in 457 individuals (235 male; median age = 8 years) met clinical criteria. The majority were Aboriginal and Torres Strait Islander children (91.2%), with 62.1% living in remote areas. The number of ARF and rheumatic heart disease (RHD) diagnoses per year increased from 1987 to 2017 with notable peaks in 2013 and 2017. The average annual incidence of tertiary-referred ARF in WA of 4-15-year-olds from 1987 to 2020 was 4.96 per 100 000. ARF features included carditis (59.9%), chorea (31%), polyarthritis (30%) and polyarthralgia (24.2%). RHD was evident in 61.8% of cases and predominantly manifested as mitral regurgitation (55.7%). Thirty-four children (7.4%) with severe RHD underwent valvular surgery. 12% had at least one recurrent ARF episode. Remote individuals had more than double the rate of recurrence compared to non-remote individuals (P = 0.0058). Compared to non-remote episodes, remote presentations had less polyarthritis (P = 0.0022) but greater proportions of raised ESR (P = 0.01), ASOT titres (P = 0.0073), erythema marginatum (P = 0.0218) and severe RHD (P = 0.0133). CONCLUSION: The high proportion of Aboriginal and Torres Strait Islander Australians affected by ARF/RHD in WA reflects the significant burden of disease within this population. Children from remote communities were more likely to present with concurrent severe RHD. Our study reinforces the persisting need to improve primary and secondary ARF initiatives in rural and remote communities.

Inclusion of echocardiography as diagnostic tool and polyarthralgia and monoarthritis as major criteria for high-risk populations in the Revised Jones Criteria 2015 is likely to surface substantial variability in clinical manifestations among various populations. This study aimed to compare clinical profile of patients presenting with first and recurrent episodes of acute rheumatic fever (ARF) using most recent criteria. 130 consecutive patients with ARF were included in the study from August 2019 to March 2022. World Heart Federation standardized echocardiographic criteria were used for cardiac evaluation. The socio-demographic variables, clinical details and relevant investigations were recorded. Median age was 13(6-26) years. Male to female ratio was 1.6:1. Majority was of low socioeconomic status (90%) and with > 5 family members in a house (83.8%). 27 patients (20.8%) were with ARF while 103 (79.2%) with recurrent ARF. Carditis was the most common presenting feature (n = 122, 93.8%), followed by polyarthralgia (n = 46, 35.4%), polyarthritis (n = 32, 24.6%), subcutaneous nodules (n = 10, 7.7%), monoarthritis (n = 10, 7.7%), and chorea (n = 5, 3.8%). Monoarthralgia was more common in ARF than recurrence (29.4% vs. 3.2%, p = 0.004). Carditis (97.1% vs. 81.5%, p = 0.01) and congestive cardiac failure (18.5% vs. 5.9%, p = 0.001) were more common in recurrent ARF than ARF. Diagnostic categorization of Jones criteria for different populations has highlighted important variability in clinical presentation of ARF. Monoarthralgia is common in first episode of ARF. Carditis is the most common feature in recurrent ARF. Polyarthralgia is seen with higher frequency that polyarthritis. Subcutaneous nodules seem to be more common in our population.

The spondyloarthropathies are a group of conditions characterised by spinal joint pain and have related clinical, epidemiological and genetic-related features. Ankylosing spondylitis, reactive arthritis, the spinal form of psoriatic arthritis and Crohn's and colitis enteropathic arthritis are the major clinical entities of the spondyloarthropathies, and principally occur in HLA-B27 positive individuals. Ankylosing spondylitis is much more common in males than females. Patients are usually seronegative for rheumatoid factor, and extra-articular features including iridocyclitis, mucous membrane and skin lesions: aortitis, may occur in some patients. The reactive arthritis form classically occurs following an infection of the gastrointestinal or genitourinary tract. The Crohn's and colitis enteropathic arthritis forms often have an associated large joint asymmetrical arthritis. Also discussed are acute rheumatic fever and Lyme disease which are conditions where the individual develops arthritis after an infection.

Streptococcus pyogenes (Strep A) infections result in a vastly underestimated burden of acute and chronic disease globally. The Strep A Vaccine Global Consortium's (SAVAC's) mission is to accelerate the development of safe, effective, and affordable S. pyogenes vaccines. The safety of vaccine recipients is of paramount importance. A single S. pyogenes vaccine clinical trial conducted in the 1960s raised important safety concerns. A SAVAC Safety Working Group was established to review the safety assessment methodology and results of more recent early-phase clinical trials and to consider future challenges for vaccine safety assessments across all phases of vaccine development. No clinical or biological safety signals were detected in any of these early-phase trials in the modern era. Improvements in vaccine safety assessments need further consideration, particularly for pediatric clinical trials, large-scale efficacy trials, and preparation for post-marketing pharmacovigilance.

In this part 1 of a 2-part continuing medical education series, we review the epidemiology and pathophysiology of cardiovascular disease, its association with cutaneous symptoms, and the diagnosis and evaluation of cutaneous features of cardiovascular syndromes, including infective endocarditis, acute rheumatic fever, Kawasaki disease, cholesterol embolization syndrome, lipid disorders, cardiac amyloidosis, and cardiac myxomas. As the incidence and prevalence of cardiovascular diseases increase, dermatologists play an essential role in recognizing the cutaneous manifestations of cardiovascular diseases in order to appropriately connect patients with follow-up care.

AIM: To describe the epidemiology and clinical profile of children and adolescents with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in Victoria, Australia. METHODS: A retrospective audit was undertaken of children and adolescents with ARF and RHD attending the Royal Children's and Monash Children's Hospitals in Victoria, Australia between 2010 and 2019. Potential cases were identified by searching multiple sources for relevant ICD-10-AM codes and keywords, then reviewed manually. For confirmed cases, we collected data on patient demographics, clinical features, comorbidities and management. RESULTS: Of 179 participants included, there were 108 Victorian residents and 71 non-Victorian residents. 126 had at least one episode of ARF during the study period and 128 were diagnosed with RHD. In the Victorian resident group, the overall incidence of ARF was 0.8 per 100 000 5-14 year olds. This incidence was higher in Victorian Aboriginal and/or Torres Strait Islander (3.8 per 100 000) and Pacific Islander (32.1 per 100 000) sub-populations. Of 83 Victorian residents who had an ARF episode, 11 (13%) had a recurrence. Most Victorian residents with RHD had mixed aortic and mitral valve pathology (69.4%) and moderate to severe disease (61.9%). Most non-Victorian residents were Aboriginal and/or Torres Strait Islander people (80.3%) and were commonly transferred for tertiary or surgical management of RHD (83.1%). CONCLUSIONS: ARF and RHD continue to affect the health of significant numbers of children and adolescents living in Victoria, including severe and recurrent disease. Specialised services and a register-based control program may help to prevent complications and premature death.

AIM: In this single-centre prospective study, we aimed to evaluate the role of growth differentiation factor-15 in children with acute rheumatic fever. METHODS: The study group included 25 children with acute rheumatic fever, and the control group included 25 healthy children. In addition to routine laboratory tests used in the diagnosis and treatment of acute rheumatic fever, growth differentiation factor-15 levels of the study group (at the time of diagnosis and after the treatment) and the control group were assessed and compared. RESULTS: The mean growth differentiation factor-15 level of the study group at the time of diagnosis (918.40 ± 605.65 pg/ml) was significantly higher than the mean post-treatment level (653.08 ± 330.92 pg/ml) (p = 0.015). Similarly, the mean growth differentiation factor-15 level of the study group at the time of diagnosis was significantly higher than the control group (p = 0.04). However, mean growth differentiation factor-15 levels were similar between the groups after the treatment. Growth differentiation factor-15 was positively correlated with both C-reactive protein (p < 0.001) and erythrocyte sedimentation rate (p = 0.001) at the time of diagnosis. CONCLUSION: Growth differentiation factor-15 levels are significantly increased in children with acute rheumatic fever at the time of diagnosis and return to similar levels with healthy children after treatment. Growth differentiation factor-15 is positively and significantly correlated with erythrocyte sedimentation rate and C-reactive protein at the time of diagnosis.

BACKGROUND: Group A Streptococcus (GAS) causes superficial pharyngitis and skin infections as well as serious autoimmune sequelae such as acute rheumatic fever (ARF) and subsequent rheumatic heart disease. ARF pathogenesis remains poorly understood. Immune priming by repeated GAS infections is thought to trigger ARF, and there is growing evidence for the role of skin infections in this process. METHODS: We utilized our recently developed 8-plex immunoassay, comprising antigens used in clinical serology for diagnosis of ARF (SLO, DNase B, SpnA), and 5 conserved putative GAS vaccine antigens (Spy0843, SCPA, SpyCEP, SpyAD, Group A carbohydrate), to characterize antibody responses in sera from New Zealand children with a range of clinically diagnosed GAS disease: ARF (nâ =â 79), GAS-positive pharyngitis (nâ =â 94), GAS-positive skin infection (nâ =â 51), and matched healthy controls (nâ =â 90). RESULTS: The magnitude and breadth of antibodies in ARF was very high, giving rise to a distinct serological profile. An average of 6.5 antigen-specific reactivities per individual was observed in ARF, compared to 4.2 in skin infections and 3.3 in pharyngitis. CONCLUSIONS: ARF patients have a unique serological profile, which may be the result of repeated precursor pharyngitis and skin infections that progressively boost antibody breadth and magnitude.

BACKGROUND: Rheumatic heart disease (RHD) is the most commonly acquired heart disease in children and young people in low and middle-income settings. Fragile health systems and scarcity of data persist to limit the understanding of the relative burden of this disease. The aims of this study were to estimate the prevalence of RHD and to assess the RHD-related health care systems in Namibia. METHODS: Data was retrieved from outpatient and inpatient registers for all patients diagnosed and treated for RHD between January 2010 to December 2020. We used descriptive statistics to estimate the prevalence of RHD. Key observations and engagement with local cardiac clinicians and patients helped to identify key areas of improvement in the systems. RESULTS: The outpatient register covered 0.032% of the adult Namibian population and combined with the cumulative incidence from the inpatient register we predict the prevalence of clinically diagnosed RHD to be between 0.05% and 0.10% in Namibia. Young people (< 18 years old) are most affected (72%), and most cases are from the north-eastern regions. Mitral heart valve impairment (58%) was the most common among patients. We identified weaknesses in care systems i.e., lack of patient unique identifiers, missing data, and clinic-based prevention activities. CONCLUSION: The prevalence of RHD is expected to be lower than previously reported. It will be valuable to investigate latent RHD and patient follow-ups for better estimates of the true burden of disease. Surveillance systems needs improvements to enhance data quality. Plans for expansions of the clinic-based interventions must adopt the "Awareness Surveillance Advocacy Prevention" framework supported by relevant resolutions by the WHO.

BACKGROUND: Acetylsalicylic acid (ASA) is a non-steroidal anti-inflammatory drug used in the treatment of acute rheumatic fever (ARF) and it can cause serious adverse effects. This study aimed to evaluate the clinical efficacy and side effects of ibuprofen in the treatment of ARF compared to the classic treatment, ASA. METHODS: Children who were hospitalized for the treatment of ARF with isolated arthritis and mild carditis between October 2015 and October 2018 and who received non-steroidal anti-inflammatory therapy were evaluated in the study. We compared the demographic data, clinical findings, efficacy, and side effects of the treatments of the children, who were divided into ASA and ibuprofen groups. RESULTS: Of the 38 patients included in the study, 21 were treated with ASA (ASA group), and 17 were given ibuprofen (IBU group). There was no difference between the groups regarding the length of hospital stay, total treatment time, time to resolution of clinical symptoms, and normalization of acute-phase reactants. Liver enzymes increased during treatment in 13 patients (62%) in the ASA group and three patients (18%) in the IBU group (P = 0.009). In the ASA group, 69% of patients with increased liver enzymes were under 11 years of age during treatment. Clinical side effects were observed in three patients in the ASA group while none were observed in the IBU group. CONCLUSION: The results of this study suggest that ibuprofen can be a safe alternative in the treatment of ARF, especially in young children. Although ibuprofen can be a safe and effective alternative to ASA, studies including larger series are needed on this subject.

BACKGROUND: Acute rheumatic fever (ARF) is a multisystemic inflammatory disease in children and young adults. The most notable complications of ARF are rheumatic heart disease (RHD) and Sydenham's chorea (SC). There have been many reports about executive dysfunctions with children who have SC. "Executive function" is an umbrella term that is used to describe higher level cognitive functions. The aim of this study is to determine the executive functions of children with RHD. We evaluated executive functions in healthy children with the same sociodemographic characteristics as children with RHD. METHODS: Our study was designed as a cross-sectional randomized study, including children with RHD aged between 12 and 18, and healthy controls. The difference between the patient and control group participants in terms of age, gender, education level, education level of the parents, family income level, and executive functions were investigated. Executive functions composed of Digit Sequence Test, Verbal Fluency Test, Trail-Making Test, Stroop Test, Wisconsin Card Sorting Test. RESULTS: In our study, a total of 30 children with RHD were followed up at the pediatric cardiology outpatient clinic of Bezmialem Vakif University Hospital composed the patient group. The control group was made up of 30 healthy children of the same sex and age group as the patient group. The mean age of the case group was 14.73 ± 1.84 years. The Digit Span Test, Verbal Fluency Test, Trail-Making Test, Wisconsin Card Sorting Test, and Stroop Test produced no statistically significant differences between the RHD patients and the controls. CONCLUSIONS: No statistically significant difference was found between the RHD patients and control patients in any executive function test. It was suggested that executive dysfunction might not develop in RHD patients before developing SC.

BACKGROUND: Acute Rheumatic Fever (ARF) is a critically important condition for which there is no diagnostic test. Diagnosis requires the use of a set of criteria comprising clinical, laboratory, electrocardiographic and echocardiographic findings. The complexity of the algorithm and the fact that clinicians lack familiarity with ARF, make ARF diagnosis ideally suited to an electronic decision support tool. The ARF Diagnosis Calculator was developed to assist clinicians in diagnosing ARF and correctly assign categories of 'possible, 'probable' or 'definite' ARF. This research aimed to evaluate the acceptability, accuracy, and test performance of the ARF Diagnosis Calculator. METHODS: Three strategies were used to provide triangulation of data. Users of the calculator employed at Top End Health Service, Northern Territory, Australia were invited to participate in an online survey, and clinicians with ARF expertise were invited to participate in semi-structured interviews. Qualitative data were analysed using inductive analysis. Performance of the calculator in correctly diagnosing ARF was assessed using clinical data from 35 patients presenting with suspected ARF. Diagnoses obtained from the calculator were compared using the Kappa statistic with those obtained from a panel of expert clinicians. RESULTS: Survey responses were available from 23 Top End Health Service medical practitioners, and interview data were available from five expert clinicians. Using a 6-point Likert scale, participants highly recommended the ARF Diagnosis Calculator (median 6, IQR 1), found it easy to use (median 5, IQR 1) and believed the calculator helped them diagnose ARF (median 5, IQR 1). Clinicians with ARF expertise noted that electronic decision making is not a substitute for clinical experience. There was high agreement between the ARF Diagnosis Calculator and the 'gold standard' ARF diagnostic process (κ = 0.767, 95% CI: 0.568-0.967). Incorrect assignment of diagnosis occurred in 4/35 (11%) patients highlighting the greater accuracy of expert clinical input for ambiguous presentations. Sixteen changes were incorporated into a revised version of the calculator. CONCLUSIONS: The ARF Diagnosis Calculator is an easy-to-use, accessible tool, but it does not replace clinical expertise. The calculator performed well amongst clinicians and is an acceptable tool for use within the clinical setting with a high level of accuracy in comparison to the gold standard diagnostic process. Effective resources to support clinicians are critically important for improving the quality of care of ARF.

Rheumatic heart disease (RHD) is the result of episodes of acute rheumatic fever with valvular (and other cardiac) damage caused by an abnormal immune response to group A streptococcal infections, usually during childhood and adolescence. As a result of improved living conditions and the introduction of penicillin, RHD was almost eradicated in the developed world by the 1980s. However, being a disease of poverty, its burden remains disproportionately high in the developing world, despite being a fundamentally preventable disease. Rheumatic heart disease generates relatively little attention from the medical and science communities, in contrast to other common infectious problems (such as malaria, HIV, tuberculosis), despite the major cardiovascular morbidity/mortality burden imposed by RHD. This relative neglect and paucity of funding have probably contributed to limited fundamental medical advances in this field for over 50 years. Given the importance of prevention before the onset of major valvular damage, the main challenges for RHD prevention are improving social circumstances, early diagnosis, and effective delivery of antibiotic prophylaxis. Early identification through ultrasound of silent, subclinical rheumatic valve lesions could provide an opportunity for early intervention. Simple echocardiographic diagnostic criteria and appropriately trained personnel can be valuable aids in large-scale public health efforts. In addition, a better understanding of the immunogenic determinants of the disease may provide potential routes to vaccine development and other novel therapies.

INTRODUCTION: Rheumatic heart disease is among the leading causes of acquired valvular heart disease in the developing world. However, there is no data available for rheumatic heart disease in the paediatric population of Sabah. This study collected data for acute rheumatic fever admissions among the paediatric population in Sabah over a period of 3 years. METHODS: This is a retrospective cohort study. All records for admissions to paediatric wards in Sabah for acute rheumatic fever from January 2016 to December 2018 were collected. The patient records were then traced and required information were collected. RESULTS: A total of 52 cases of acute rheumatic fever were admitted. It was observed that the incidence of acute rheumatic fever was 74.4 per 100,000 paediatric admissions. Patients from the West Coast Division made up most of the admissions (n = 24, 46.2%). Male patients (n = 35, 67.3%) of the indigenous Kadazan-Dusun ethnicity (n = 21, 40.4%) were most commonly encountered. The mean age at time of presentation was 9.58 years. Most cases admitted (n = 38, 73.1%) were categorised as Priority 1 (severe rheumatic heart disease). CONCLUSION: Most patients who were admitted had symptoms of heart failure and were diagnosed with severe rheumatic heart disease. Although this disease is preventable, the incidence in Sabah remains high. This study was limited as we only looked at patients who were admitted and we foresee the real incidence to be higher. Hence, there is an urgent need for a rheumatic heart disease registry in Malaysia to gather more data for prevention and early intervention.

INTRODUCTION: Acute rheumatic fever is an autoimmune disease that develops due to streptococcal infection. The positive effect of breastfeeding on the development of the child's immune system is well documented. In this study, we aimed to investigate the effect of breast milk intake period on the development of carditis. MATERIALS AND METHODS: Patients (n: 182) who were diagnosed with acute rheumatic fever between 2010 and 2019 were enrolled in the study. The patients were divided into groups according to carditis development. The demographic, socio-economic, and breastfeeding data were compared between groups. RESULTS: The mean age of the patients was 10.5 ± 3.4, and 43.4 % (n: 79) of them were female. Independent predictors of the development of carditis in the first acute rheumatic fever episode were the number of children at home (OR: 1.773, CI 95%: 1.105, 2.845; p: 0.018) and breast milk intake less than 6 months (OR: 0.404, CI 95%: 0.174, 0.934; p: 0.034). Independent predictors of the development of carditis in any of the acute rheumatic fever episodes were the number of children at home (OR: 1.858, CI 95%: 1.100, 3.137; p: 0.021) and female gender (OR: 3.504, CI 95%: 1.227, 10.008; p: 0.019). The only independently predictor of the development of chorea during acute rheumatic fever was female gender (OR: 3.801, CI 95%: 1.463, 9.874; p: 0.006). CONCLUSION: Although the occurrence of carditis is less common during the first acute rheumatic fever attack in patients with breast milk intake less than six months, this advantage is lost in recurrent attacks. This study showed that breast milk does not have a negative effect on acute rheumatic fever carditis.
RESUMO
Australia's national clinical practice guidelines recommend intramuscular (IM) penicillin every 28 days for persons diagnosed with an initial episode of acute rheumatic fever (ARF). This antibiotic coverage is initiated to reduce recurrent ARF episodes by preventing repeat infections with the causative bacterium, group A Streptococcus. Because disease has already occurred, this regimen is known as secondary prophylaxis (SP), done in order to prevent more episodes of ARF (known as recurrences). In 2020, eight authors shared with readers of Rural and Remote Health their experience of introducing off-label an oral, centrally acting, alpha agonist sedative to the prescribed SP regimen of IM penicillin for each of three Aboriginal children previously diagnosed with ARF. The living environments of the three children increased their risk for repeat group A Streptococcus infections and subsequent recurrences of ARF. We find the clinical case report perpetuates a troubling academic tone about this singular priority for SP. Injecting a child with IM penicillin appears to supersede all other objectives. Off-label sedation in remote settings is legitimised in order to succeed in this imperative. Those articles that peer-reviewed medical journals choose to publish privilege directions for priorities, policy and practice. In this commentary, we present alternative perspectives and initiatives for consideration.
