Whānau perceptions and experiences of acute rheumatic fever diagnosis for Māori in Northland, New Zealand.

In New Zealand, acute rheumatic fever (ARF) remains a significant health problem with persistent ethnic inequities. Māori children 5-15 years of age in Northland have some of the highest ARF rates nationally. This study explored Māori whānau experiences of ARF, including pathways to primary healthcare and barriers and facilitators for diagnosis of ARF.

Genome-Wide Analysis of Genetic Risk Factors for Rheumatic Heart Disease in Aboriginal Australians Provides Support for Pathogenic Molecular Mimicry.

Rheumatic heart disease (RHD) after group A streptococcus (GAS) infections is heritable and prevalent in Indigenous populations. Molecular mimicry between human and GAS proteins triggers proinflammatory cardiac valve-reactive T cells.

Impact of prosthesis-patient mismatch after mitral valve replacement in rheumatic population: Does mitral position prosthesis-patient mismatch really exist?

Prosthesis-patient mismatch (PPM) is characterised by the effects of inadequate prosthesis size relative to body surface area (BSA).The purpose of this study was to determine the impact of PPM on late clinical outcomes after mitral valve replacement (MVR) in rheumatic population.

Latent Rheumatic Heart Disease: Identifying the Children at Highest Risk of Unfavorable Outcome.

Screening echocardiography has emerged as a potentially powerful tool for early diagnosis of rheumatic heart disease (RHD). The utility of screening echocardiography hinges on the rate of RHD progression and the ability of penicillin prophylaxis to improve outcome. We report the longitudinal outcomes of a cohort of children with latent RHD and identify risk factors for unfavorable outcomes.

Congenital and Acquired Valvular Heart Disease in Pregnancy.

The number of pregnancies complicated by valvular heart disease is increasing. This review describes the hemodynamic effects of clinically important valvular abnormalities during pregnancy and reviews current guideline-driven management strategies.

Global, Regional, and National Burden of Rheumatic Heart Disease, 1990-2015.

Rheumatic heart disease remains an important preventable cause of cardiovascular death and disability, particularly in low-income and middle-income countries. We estimated global, regional, and national trends in the prevalence of and mortality due to rheumatic heart disease as part of the 2015 Global Burden of Disease study.

Rheumatic Heart Disease - An Iceberg in Tropical Waters.

Surgical Treatment of Atrial Fibrillation in Patients with Rheumatic Valve Disease.

To assess heart rhythm and predictive factors associated with sinus rhythm after one year in patients with rheumatic valve disease undergoing concomitant surgical treatment of atrial fibrillation. Operative mortality, survival and occurrence of stroke after one year were also evaluated.

Is a rheumatic fever register the best surveillance tool to evaluate rheumatic fever control in the Auckland region?

To determine the most accurate data source for acute rheumatic fever (ARF) epidemiology in the Auckland region.

Emm type distribution of group A streptococcus isolates from the throat swabs of children living in areas with a high (Northland and Gisborne) or low (Palmerston North) incidence of acute rheumatic fever.

To assess the circulating emm types of pharyngeal isolates of group A streptococcus (GAS) among school children living in Northland, the Gisborne region and Palmerston North, New Zealand.

Rheumatic fever as an indicator of child health.

Net atrioventricular compliance is an independent predictor of cardiovascular death in mitral stenosis.

Rheumatic mitral stenosis (MS) is a progressive disease, and risk of death may persist despite relief of the obstruction. Net atrioventricular compliance (Cn) modulates the overall haemodynamic burden of the MS and may be useful in predicting cardiovascular death after percutaneous mitral valvuloplasty (PMV).

Eliminating acute rheumatic fever and rheumatic heart disease.

Epidemiology of pharyngitis as reported by Zambian school children and their families: implications for demand-side interventions to prevent rheumatic heart disease.

Prompt and appropriate treatment of streptococcal pharyngitis decreases the risk of acute rheumatic fever and rheumatic heart disease (RHD). Understanding public perceptions and behaviors related to sore throat is fundamental to inform health programs aimed at eliminating new cases of RHD in endemic regions. We sought to describe the epidemiology of pediatric pharyngitis and its treatment, as reported by children and their parents or guardians in Lusaka, Zambia.

Sex-dependent aortic valve pathology in patients with rheumatic heart disease.

Rheumatic heart disease is an autoimmune disease caused by group A streptococci infection and frequently affects the aortic valve. Sex differences are common in the disease progression, treatment, and outcome. However, little is known about the sex differences in the pathology of aortic valves in rheumatic heart disease.

Total Chordal Sparing Mitral Valve Replacement in Rheumatic Disease: A Word of Caution.

Total chordal preservation is the standard for mitral valve replacement to maintain long-term left ventricular geometry. Whereas it is appropriate for functional and degenerative mitral regurgitation, the role of chordal sparing in rheumatic valve disease is less well understood, with limited evidence supporting total chordal sparing. Inasmuch as this autoimmune disease affects the subvalvular apparatus in addition to the leaflets, it can be expected to continue after surgical repair. Here we present 2 patients who experienced adverse events associated with total chordal sparing mitral replacement as a result of disease progression with rapid fibrous growth causing inflow obstruction and early prosthetic valve failure.

DNA methylation dysregulations in rheumatic heart valve disease.

The epigenetic changes underlying the development of rheumatic heart valve disease (RHVD) remain incompletely understood. Limited evidence suggests that abnormal DNA methylation might be involved in the pathogenesis of RHVD. In the present study, we evaluated the DNA methylation dysregulations from myocardial tissue in RHVD patients systematically.

Clinical management and patient persistence with antibiotic course in suspected group A streptococcal pharyngitis for primary prevention of rheumatic fever: the perspective from a New Zealand emergency department.

Rates of acute rheumatic fever in the Northland region are historically among the highest in New Zealand, impacting disproportionately on Māori children and youth. The primary aim of this study was to determine patient persistence to antibiotic treatment for group A streptococcus (GAS) pharyngitis in patients presenting with sore throat to the Whangarei Hospital Emergency Department. Secondarily, this study sought to determine prescriber adherence to the national antibiotic guideline for sore throat management.

Adequate adherence to benzathine penicillin secondary prophylaxis following the diagnosis of rheumatic heart disease by echocardiographic screening.

The primary aim of this study was to determine adherence to benzathine penicillin (BPG) for individuals diagnosed with rheumatic heart disease (RHD) by echocardiographic screening between 2007-2012.

Acute rheumatic fever: clinical profile in children in western Ukraine.

Acute rheumatic fever (ARF) may have different clinical manifestations in different countries according to the genetic predisposition, prevalence of rheumatogenic strains, social and economic conditions. The purpose of this study was to determine the clinical characteristics of ARF in Western Ukraine and to improve the detection of the cases. A retrospective analysis of 85 medical clinical cases of in-hospital patients aged from 4 to 17 years old was performed. The cases covered patients who underwent treatment in the City Children's Hospital of Ternopil during 2000 and 2013 with the ARF diagnosis, which was established according to Jones criteria. 65.9% of the ARF patients were admitted to the hospital from October to March. Fever (65.9%) and joint syndrome (78.8%) were the most common causes for admission to the medical care. The admission diagnosis was wrong in 34 (40.0%) children who underwent the treatment. The most frequent major Jones criteria of ARF were carditis (84.7%) and polyarthritis (54.1%). Chorea was significantly less common than carditis (р < 0,001). The adequate treatment of the preceding streptococcal infection was administered in 25 children (53.2%).

Minimally invasive mitral valve replacement is a safe and effective surgery for patients with rheumatic valve disease: A retrospective study.

The aim of the study was to evaluate the treatment of minimally invasive mitral valve replacement (MIMVR) through a right minithoracotomy for patients with rheumatic mitral valve disease.From February 2009 to December 2016, 360 patients with rheumatic mitral valve disease underwent mitral valve replacement by the same surgeon. Among them, 150 patients accepted MIMVR through a right minithoracotomy, whereas the other 210 accepted a traditional median sternotomy. After matching by patients by age, sex, EuroSCORE, New York Heart Association (NYHA) classification, renal and liver function, and degree of mitral valve disease, we selected 224 patients for analysis in our retrospective study.In the MIMVR group (112 patients), the aortic cross-clamp time (ACC time) (55.25 ± 2.18 minutes) was significantly longer than that in the control group (112 patients; 36.05 ± 1.40 minutes) (P < .0001). In contrast, the cardiopulmonary bypass time (CPB time) was shorter in the MIMVR group than in the control group (61.13 ± 2.57 vs 78.65 ± 4.05 minutes, respectively, P < .0001). Patients who accepted MIMVR surgery had less drainage 24 hours postoperation (324.10 ± 34.55 vs 492.90 ± 34.05 mL, P < .0001) and had less total drainage (713.46 ± 65.35 vs 990.49 ± 67.88 mL, P < .0001) than those who underwent median sternotomy. Thirty-two percent of patients in the MIMVR group needed a blood transfusion (1.35 ± .28 units of red blood cells, 155.36 ± 33.43 mL plasma), whereas 67.0% of the control group needed a blood transfusion (2.15 ± .24 units of red blood cells, 287.50 ± 33.54 mL plasma) (Ptransfusion < .001, Pcell = .029, Pplasma = .006). In total, 5 deaths occurred during the perioperative period; 3 occurred in the MIMVR group. The average hospital stay was significantly shorter in the MIMVR group than that in the control group (6.56 ± .23 vs 8.53 ± .59 days, P = .003).MIMVR, an effective and safe treatment approach for patients suffering from rheumatic mitral valve disease, is associated with less trauma and a faster recovery. It is a better choice for treating simple rheumatic mitral valve disease.

Adherence to secondary prophylaxis for rheumatic heart disease is underestimated by register data.

In high-burden Australian states and territories, registers of patients with acute rheumatic fever and rheumatic heart disease are maintained for patient management, monitoring of system performance and research. Data validation was undertaken for the Australian Northern Territory Rheumatic Heart Disease Register to determine quality and impact of data cleaning on reporting against key performance indicators: overall adherence, and proportion of patients receiving ≥80% of scheduled penicillin doses for secondary prophylaxis.

Acute rheumatic fever and isolated myocarditis.

Immuno-nephelometric determination of group streptococcal anti-streptolysin O titres (ASOT) from dried blood spots: Method for validating a new assay.

This study was designed to determine the sensitivity and reproducibility of recovering anti-streptolysin O titres (ASOT) from dried blood spot (DBS) samples, a methodologic subcomponent of the penicillin pharmacokinetic studies in children receiving secondary prophylaxis with intramuscular benzathine penicillin for acute rheumatic fever.
