Abstract
Background Physiological changes during pregnancy cause complications in mothers with mitral stenosis and their infants. This study was designed to assess maternal and fetal pregnancy outcomes in women with rheumatic mitral valve stenosis and compare them with the control group. Materials and methods This study is a case-control study on 153 pregnant women, including 51 with mitral stenosis (MS) and 102 without MS as the control group, between 2007-2022. For each studied patient, two control participants were selected and matched in residence, age, and year of pregnancy. SPSS version 22 was used for data analysis. Results The mean age was 31.7 ± 4.6 years in cases and 31.6 ± 4.7 in the healthy controls. Demographic variables were not significantly different between the case and control groups. The rate of stillbirth (5.9% vs. 0.0%), %), NICU admission (13.7% vs. 2.0%), and IUGR (5.9% vs. 0.0%) were higher in the fetal case group compared with the control group. On the other hand, maternal outcomes, including pulmonary edema (13.7% vs. 0.0%), ICU admission (23.5% vs. 0.0%), limb edema (15.7% vs. 0.0%), dyspnea (37.3% vs. 0.0%), pulmonary hypertension (9.8% vs. 0.0%), palpitations (21.1% vs. 0.0%) and hospital admission during pregnancy (37.2% vs. 4.9%) were statistically more common in the case groups. Conclusions Pregnancy is associated with significant fetomaternal morbidities in women with mitral valve heart disease. So they need a multidisciplinary approach in preconception and antenatal care.

Abstract
Background and Aim Rheumatic heart disease (RHD) is a significant cause of heart failure in sub-Saharan Africa. The causes of death from RHD are multiple, many of which can be prevented with appropriate follow-up of patients and effective secondary prophylaxis. An RHD Clinic was initiated to attempt a solution in Yaoundé, Cameroon. Over 6 months, its impact was evaluated. Methods Two echocardiography registers were accessed, and patients diagnosed with RHD between 2005 and 2018 were contacted. Consenting carers and patients pioneered the first RHD Clinic. Activities of the clinic comprised health education, medical visits, and benzylpenicillin G (BPG) injections. Text messages and phone calls were used to remind patients of their monthly appointments. Results Out of 1200 first-time cardiac ethnographies, 70 patients (5.83%) had been diagnosed with RHD. The case fatality rate of RHD was 16.67%. Twenty-three patients were successfully registered and followed-up by the clinic, 70% of whom were female. The age range was 4-22 years. Fifty-three percent had an NYHA score of 2 or more at the time of admission into the clinic. There was an increase in adherence to secondary prophylaxis with BPG from 42.9% at baseline to 87%-95% in the last 3 months. Conclusion Our short experience running an RHD Clinic was marked by increased treatment adherence among persons living with RHC.

Liang Y, Yu D, Lu Q, Zheng Y, Yang Y. The rise and fall of acute rheumatic fever and rheumatic heart disease: a mini review. Front Cardiovasc Med 2023; 10:1183606. [PMID: 37288267 PMCID: PMC10242100 DOI: 10.3389/fcvm.2023.1183606] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 05/10/2023] [Indexed: 06/09/2023] Open
Abstract
Introduction The incidences of acute rheumatic fever (ARF) and rheumatic heart disease (RHD), which were leading causes of death in children in the 1920s, have decreased substantially. Considering the recent resurgence of scarlet fever and increased incidence of streptococcal pharyngitis in children, an investigation of the current status of ARF and RHD may be worthwhile. Objective To summarize the prevalence trends, pathogenic factors, and prevention strategies for ARF and RHD in children. Methods A selective search of literature published between January 1920 and February 2023 was done in PubMed, using the terms "acute rheumatic fever", "rheumatic heart disease", "group A Streptococcus", "pharyngitis", "pharyngeal tonsillitis", "scarlet fever", "impetigo", "obstructive sleep apnea syndrome" and "child". Results Overcrowded homes and inadequate sanitation led to recurrent group A streptococcal infection, and the causal relationship between group A streptococcal infection and ARF/RHD was well established. Streptococcal infectious diseases, such as group A streptococcal pharyngeal tonsillitis, SF, impetigo, and obstructive sleep apnea syndrome, were associated with the occurrence of ARF and RHD. ARF and RHD were still prevalent in young people of developing countries and economically poor populations of high-income countries. Universal disease registration systems were critical to locating disease outbreaks, tracking disease transmission, and identifying high-risk populations. Four-level prevention strategies were effective in reducing the incidence and mortality of ARF and RHD. Conclusions Registry and preventive measures for ARF and RHD should be strengthened in areas of dense population; poor sanitation; resurgence of SF; and high incidence of streptococcal pharyngitis, impetigo, and obstructive sleep apnea syndrome.

Abstract
Objective. Rheumatic Heart Disease (RHD) is one of the highly prevalent heart diseases in developing countries that can affect the pericardium, myocardium, or endocardium. Rheumatic endocarditis is a common RHD variant that gradually deteriorates the normal function of the heart valves. RHD can be diagnosed using standard echocardiography or listened to as a heart murmur using a stethoscope. The electrocardiogram (ECG), on the other hand, is critical in the study and identification of heart rhythms and abnormalities. The effectiveness of ECG to identify distinguishing signs of rheumatic heart problems, however, has not been adequately examined. This study addressed the possible use of ECG recordings for the characterization of problems of the heart in RHD patients.Approach. To this end, an extensive ECG dataset was collected from patients suffering from RHD (PwRHD), and healthy control subjects (HC). Bandpass filtering was used at the preprocessing stage. Each data was then standardized by removing its mean and dividing by its standard deviation. Delineation of the onsets and offsets of waves was performed using KIT-IBT open ECG MATLAB toolbox. PR interval, QRS duration, RR intervals, QT intervals, and QTc intervals were computed for each heartbeat. The median values of the temporal parameters were used to eliminate possible outliers due to missed ECG waves. The data were clustered in different age groups and sex. Another categorization was done based on the time duration since the first RHD diagnosis.Main results. In 47.2% of the cases, a PR elongation was observed, and in 26.4% of the cases, the QRS duration was elongated. QTc was elongated in 44.3% of the cases. It was also observed that 62.2% of the cases had bradycardia.Significance. The end product of this research can lead to new medical devices and services that can screen RHD based on ECG which could somehow assist in the detection and diagnosis of the disease in low-resource settings and alleviate the burden of the disease.

Abstract
Objective Rheumatic mitral valve disease is often viewed as a historic disease in North America with limited contemporary data. We hypothesized that rheumatic pathology remains common and has worse short‐term outcomes and higher resource utilization compared to other mitral valve pathologies. Method All patients undergoing mitral valve repair or replacement (2011–2019) were extracted from a regional Society of Thoracic Surgeons database. Resource utilization metrics included inflation‐adjusted hospital costs. Patients were stratified by mitral valve pathology for univariate analysis. Result Out of the 6625 mitral valve procedures, 835 (12.6%) were from rheumatic disease, a proportion that incrementally increased over time (+0.39% per year, p = .032). Among 19 hospitals, there was high variability in number of rheumatic mitral operations (median: 22, interquartile range [IQR]: 5–80) and rate of rheumatic repairs (median: 3%, IQR: 0%–6%). Rheumatic patients were younger (62 vs. 65, p < .0001), more often female (75% vs. 43%, p < .001) and with greater burden of heart failure, multi‐valve disease, and lung disease, but less coronary disease. There were no differences in operative mortality (5.2% vs. 5.0%, p = .85) or major morbidity (22.2% vs. 21.8%, p = .83). However, resource utilization was higher for rheumatic patients, including more frequent transfusions (43% vs. 39%, p = .012), longer ICU (73 vs. 64 h, p < .0001) and postoperative length of stay (8 vs. 7 days, p < .0001). Conclusions Rheumatic mitral disease accounts for a meaningful (12%) and rising percentage of mitral valve operations in the region, with high variability among hospitals. Rheumatic mitral surgery yielded similar short‐term outcomes compared to nonrheumatic pathology, but required greater resource utilization.

Abstract
Nearly a century after rheumatic fever (RF) and rheumatic heart disease (RHD) was eradicated from the developed world, the disease remains endemic in many low- and middle-income countries (LMICs), with grim health and socioeconomic impacts. The neglect of RHD which persisted for a semi-centennial was further driven by competing infectious diseases, particularly the human immunodeficiency virus (HIV) pandemic. However, over the last two-decades, slowly at first but with building momentum, there has been a resurgence of interest in RF/RHD. In this narrative review, we present the advances that have been made in the RF/RHD continuum over the past two decades since the re-awakening of interest, with a more concise focus on the last decade’s achievements. Such primary advances include understanding the genetic predisposition to RHD, group A Streptococcus (GAS) vaccine development, and improved diagnostic strategies for GAS pharyngitis. Echocardiographic screening for RHD has been a major advance which has unearthed the prevailing high burden of RHD and the recent demonstration of benefit of secondary antibiotic prophylaxis on halting progression of latent RHD is a major step forward. Multiple befitting advances in tertiary management of RHD have also been realized. Finally, we summarize the research gaps and provide illumination on profitable future directions towards global eradication of RHD.

Abstract
Importance Rheumatic heart disease (RHD), a sequela of rheumatic fever characterized by permanent heart valve damage, is the leading cause of cardiac surgery in Africa. However, its pathophysiologic characteristics and genetics are poorly understood. Understanding genetic susceptibility may aid in prevention, control, and interventions to eliminate RHD. Objective To identify common genetic loci associated with RHD susceptibility in Black African individuals. Design, Setting, and Participants This multicenter case-control genome-wide association study (GWAS), the Genetics of Rheumatic Heart Disease, examined more than 7 million genotyped and imputed single-nucleotide variations. The 4809 GWAS participants and 116 independent trio families were enrolled from 8 African countries between December 31, 2012, and March 31, 2018. All GWAS participants and trio probands were screened by use of echocardiography. Data analyses took place from May 15, 2017, until March 14, 2021. Main Outcomes and Measures Genetic associations with RHD. Results This study included 4809 African participants (2548 RHD cases and 2261 controls; 3301 women [69%]; mean [SD] age, 36.5 [16.3] years). The GWAS identified a single RHD risk locus, 11q24.1 (rs1219406 [odds ratio, 1.65; 95% CI, 1.48-1.82; P = 4.36 × 10-8]), which reached genome-wide significance in Black African individuals. Our meta-analysis of Black (n = 3179) and admixed (n = 1055) African individuals revealed several suggestive loci. The study also replicated a previously reported association in Pacific Islander individuals (rs11846409) at the immunoglobulin heavy chain locus, in the meta-analysis of Black and admixed African individuals (odds ratio, 1.16; 95% CI, 1.06-1.27; P = 1.19 × 10-3). The HLA (rs9272622) associations reported in Aboriginal Australian individuals could not be replicated. In support of the known polygenic architecture for RHD, overtransmission of a polygenic risk score from unaffected parents to affected probands was observed (polygenic transmission disequilibrium testing mean [SE], 0.27 [0.16] SDs; P = .04996), and the chip-based heritability was estimated to be high at 0.49 (SE = 0.12; P = 3.28 × 10-5) in Black African individuals. Conclusions and Relevance This study revealed a novel candidate susceptibility locus exclusive to Black African individuals and an important heritable component to RHD susceptibility in African individuals.

Abstract
Background Recent evaluation of rheumatic heart disease (RHD) mortality demonstrates disproportionate disease burden within the United States. However, there are few contemporary data on US children living with acute rheumatic fever (ARF) and RHD. Methods and Results Twenty‐two US pediatric institutions participated in a 10‐year review (2008–2018) of electronic medical records and echocardiographic databases of children 4 to 17 years diagnosed with ARF/RHD to determine demographics, diagnosis, and management. Geocoding was used to determine a census tract‐based socioeconomic deprivation index. Descriptive statistics of patient characteristics and regression analysis of RHD classification, disease severity, and initial antibiotic prescription according to community deprivation were obtained. Data for 947 cases showed median age at diagnosis of 9 years; 51% and 56% identified as male and non‐White, respectively. Most (89%) had health insurance and were first diagnosed in the United States (82%). Only 13% reported travel to an endemic region before diagnosis. Although 96% of patients were prescribed secondary prophylaxis, only 58% were prescribed intramuscular benzathine penicillin G. Higher deprivation was associated with increasing disease severity (odds ratio, 1.25; 95% CI, 1.08–1.46). Conclusions The majority of recent US cases of ARF and RHD are endemic rather than the result of foreign exposure. Children who live in more deprived communities are at risk for more severe disease. This study demonstrates a need to improve guideline‐based treatment for ARF/RHD with respect to secondary prophylaxis and to increase research efforts to better understand ARF and RHD in the United States.

Abstract
BACKGROUND The present study is based on the World Heart Federation (WHF) echocardiographic criteria to assess the prevalence of subclinical rheumatic heart disease (RHD) and elucidate evolution of the disease when the cases were placed on appropriate antibiotic prophylaxis and regular follow-up. The prevalence of subclinical RHD reported by previous active surveillance studies among asymptomatic school children is not comparable to our study because of major differences in screening methods. METHODS A random inclusion strategy was adopted to recruit urban and rural school children of Bikaner district in the state of Rajasthan, India. The diagnosis of RHD was based on the echocardiographic criteria proposed by the WHF. All studies were reported on-site by a single experienced cardiologist and the digitally preserved studies were reported by a second cardiologist off-site. The final diagnosis was made by consensus. The second echocardiogram was performed for cases diagnosed with RHD after two years from start of study to document early evolution of the disease with ongoing antibiotic prophylaxis. RESULTS A high prevalence of subclinical RHD was observed in the study population. Pathological mitral and/or aortic valve regurgitation was the commonest lesion, and a significant proportion of cases improved while on regular antibiotic prophylaxis. No case showed fixity of leaflets/ stenosis. CONCLUSION The prevalence of subclinical RHD is high in the study population, and the disease seems to regress over time in the presence of appropriate antibiotic prophylaxis.

Abstract
During the 1920s, acute rheumatic fever (ARF) was the leading cause of mortality in children in the United States. By the 1980s, many felt ARF had all but disappeared from the US. However, although ARF and rheumatic heart disease (RHD) rates remain low in the US today, disease burden is unequal and tracks along other disparities of cardiovascular health. It is estimated that 1% to 3% of patients with untreated group A streptococcus (GAS) infection, most typically GAS pharyngitis, will develop ARF, and of these, up to 60% of cases will result in chronic RHD. This article reviews the epidemiology, pathogenesis, diagnosis, and management of ARF/RHD to increase awareness of ARF/RHD for clinicians based in the US. [Pediatr Ann. 2021;50(3):e98-e104.].

LANCET GLOBAL HEALTH 2020; 8:e1489-e1498.

Abstract
BACKGROUND Non-communicable diseases (NCDs) cause a large burden of disease globally. Some infectious diseases cause an increased risk of developing specific NCDs. Although the NCD burden from some infectious causes has been quantified, in this study, we aimed to more comprehensively quantify the global burden of NCDs from infectious causes. METHODS In this modelling study, we identified NCDs with established infectious risk factors and infectious diseases with long-term non-communicable sequelae, and did narrative reviews between April 11, 2018, and June 10, 2020, to obtain relative risks (RRs) or population attributable fractions (PAFs) from studies quantifying the contribution of infectious causes to NCDs. To determine infection-attributable burden for the year 2017, we applied estimates of PAFs to estimates of disease burden from the Global Burden of Disease Study (GBD) 2017 for pairs of infectious causes and NCDs, or used estimates of attributable burden directly from GBD 2017. Morbidity and mortality burden from these conditions was summarised with age-standardised rates of disability-adjusted life-years (DALYs), for geographical regions as defined by the GBD. Estimates of NCD burden attributable to infectious causes were compared with attributable burden for the groups of risk factors with the highest PAFs from GBD 2017. FINDINGS Globally, we quantified 130 million DALYs from NCDs attributable to infection, comprising 8·4% of all NCD DALYs. The infection-NCD pairs with the largest burden were gastric cancer due to H pylori (14·6 million DALYs), cirrhosis and other chronic liver diseases due to hepatitis B virus (12·2 million) and hepatitis C virus (10·4 million), liver cancer due to hepatitis B virus (9·4 million), rheumatic heart disease due to streptococcal infection (9·4 million), and cervical cancer due to HPV (8·0 million). Age-standardised rates of infection-attributable NCD burden were highest in Oceania (3564 DALYs per 100 000 of the population) and central sub-Saharan Africa (2988 DALYs per 100 000) followed by the other sub-Saharan African regions, and lowest in Australia and New Zealand (803 DALYs per 100 000) followed by other high-income regions. In sub-Saharan Africa, the proportion of crude NCD burden attributable to infectious causes was 11·7%, which was higher than the proportion of burden attributable to each of several common risk factors of NCDs (tobacco, alcohol use, high systolic blood pressure, dietary risks, high fasting plasma glucose, air pollution, and high LDL cholesterol). In other broad regions, infectious causes ranked between fifth and eighth in terms of crude attributable proportions among the nine risks compared. The age-standardised attributable proportion for infectious risks remained highest in sub-Saharan Africa of the broad regions, but age-standardisation caused infectious risks to fall below dietary risks, high systolic blood pressure, and fasting plasma glucose in ranked attributable proportions within the region. INTERPRETATION Infectious conditions cause substantial NCD burden with clear regional variation, and estimates of this burden are likely to increase as evidence that can be used for quantification expands. To comprehensively avert NCD burden, particularly in low-income and middle-income countries, the availability, coverage, and quality of cost-effective interventions for key infectious conditions need to be strengthened. Efforts to promote universal health coverage must address infectious risks leading to NCDs, particularly in populations with high rates of these infectious conditions, to reduce existing regional disparities in rates of NCD burden.

Abstract
Kawasaki disease and acute rheumatic fever are two major causes of acquired heart disease in the pediatric population. Although both conditions are well-known entities, the association between them has never been described. We report herein a case of 6-year-old male patient who first presented with Kawasaki shock syndrome, followed by acute rheumatic fever 1 year later. In contrast to the prompt intervention given for atypical Kawasaki disease, in the present case the diagnosis was significantly delayed during the otherwise typical presentation of acute rheumatic fever. Our case highlights the difficulty experienced by many pediatricians in developed nations in diagnosing acute rheumatic fever due to its comparative rarity. To prevent diagnostic errors, all pediatricians should be alert to the possibility of acute rheumatic fever even if they are practicing in areas where it is not endemic.

Abstract
The goal of this paper is to analyze a little-known set of documents referring to a "Dancing Epidemic" that took place in Itapagipe, a suburb of Salvador, capital of the province of Bahia, Brazil, in 1882. Through the studies of a group of physicians, especially Raimundo Nina Rodrigues (1862-1906), a psychiatrist and anthropologist from the Bahia School of Medicine, the medical knowledge built on this unique phenomenon in Brazilian history is examined. The case in particular involved a crowd that spread through the streets of Itapagipe, attracting the interest of the medical classes, who were intrigued by the symptoms of motor incoordination the patients manifested. Inspired by foreign literature, but developing their own theories, Rodrigues and colleagues created a unique body of knowledge about the infirmity.

Abstract
Rosacea is one of the most common and misunderstood dermatologic conditions. Currently, rosacea criteria are based on expert opinion; the definition of rosacea is primarily a reflection of opinion that is prone to bias. It has been more than a decade since the initial criteria were created by the National Rosacea Society. Revisiting the criteria and incorporating evidence-based techniques used by rheumatology and psychiatry can improve the validity and reliability of rosacea criteria. Literature from other specialties is reviewed and a method proposed for developing valid criteria. Examples are provided to motivate and highlight the importance of implementing such techniques.

Abstract
Rheumatic heart disease (RHD) is the most serious manifestations of rheumatic fever, which is caused by group A Streptococcus (GAS or Streptococcus pyogenes) infection. RHD is an auto immune sequelae of GAS pharyngitis, rather than the direct bacterial infection of the heart, which leads to chronic heart valve damage. Although antibiotics like penicillin are effective against GAS infection, improper medical care such as poor patient compliance, overcrowding, poverty, and repeated exposure to GAS, leads to acute rheumatic fever and RHD. Thus, efforts have been put forth towards developing a vaccine. However, a potential global vaccine is yet to be identified due to the widespread diversity of S. pyogenes strains and cross reactivity of streptococcal proteins with host tissues. In this review, we discuss the available vaccine targets of S. pyogenes and the significance of in silico approaches in designing a vaccine for RHD.
