Chronic rheumatic heart disease with recrudescence of acute rheumatic fever on histology: a case report.

ABSTRACT:

Background

Rheumatic heart disease (RHD) is endemic in sub-Saharan Africa where it is the leading cause of cardiovascular mortality in the young. Rheumatic heart disease results from recurrent episodes of acute rheumatic fever (ARF), which are often difficult to diagnose clinically. Acute rheumatic fever may be diagnosed based on the revised Jones Criteria 2015 for the diagnosis of ARF. Histologically, acute rheumatic valvulitis manifests with active inflammation characterized by lymphocytic infiltration, Aschoff bodies, and Anitschkow cells. Chronic rheumatic valvulitis is associated with neovascularization, and/or dystrophic calcification. The combination of histological features of both ARF and chronic RHD is a rare finding.

Case summary

Here we report on a case of a 59-year-old woman with mixed aortic and mitral valve disease of probable rheumatic aetiology (elevated C-reactive protein and prolonged PR interval) and with histological evidence of lymphocytic infiltration, Aschoff bodies, and fibrinoid necrosis admixed with features of chronic RHD.

Discussion

Cases of chronic RHD admixed with ARF are very rare; however, they should be considered in regions with a high prevalence of RHDs.

Profiling system-wide variations between Acute Rheumatic Fever and Rheumatic Heart Disease

Project description:Rheumatic heart disease (RHD) continues to affect developing countries with low income, due to the lack of resources and effective diagnostic techniques. Understanding the genetic basis of progression from its prequel disease state, acute rheumatic fever (ARF), would aid in developing predictive biomarkers and improving patient care. To gain system-wide molecular insights into possible causes for progression, we collected blood transcriptomes from ARF (5) and RHD (5) patients. Using an integrated transcriptome and network analysis, we identified a subnetwork comprising the most significantly differentially expressed genes and most perturbed pathways in RHD as compared to ARF. For example, the chemokine signaling pathway was seen to be upregulated while tryptophan metabolism was found to be downregulated in RHD. The subnetworks of variation between the two conditions provide unbiased molecular-level insights into the host processes that may be associated with the progression of ARF to RHD, which has the potential to inform future diagnostics and therapeutic strategies. We also found significantly raised neutrophil/lymphocyte ratio in both ARF and RHD cohorts. Activated neutrophils and inhibited NK cell gene signatures reflected the drivers of the inflammatory process being common to both the disease conditions.

Concurrent diagnosis of infective endocarditis and acute rheumatic fever: A case report.

Project description:Rheumatic heart disease has been classically considered as a risk factor for infective endocarditis (IE). Although valvulitis is frequently present in patients with acute rheumatic fever (ARF), the established valve disease after initial episode of ARF is usually considered as a predisposing factor for IE. We hereby present a biopsy-proven case of IE co-diagnosed with the first episode of ARF. <Learning objective: Infective endocarditis and acute rheumatic fever are both diagnosed with clinical criteria. When both of these conditions are possible in a single case, however, the diagnosis might be challenging. We highlight this issue in the presented case.>.

Rising Ethnic Inequalities in Acute Rheumatic Fever and Rheumatic Heart Disease, New Zealand, 2000-2018.

Project description:We describe trends in acute rheumatic fever (ARF), rheumatic heart disease (RHD), and RHD deaths among population groups in New Zealand. We analyzed initial primary ARF and RHD hospitalizations during 2000-2018 and RHD mortality rates during 2000-2016. We found elevated rates of initial ARF hospitalizations for persons of Māori (adjusted rate ratio [aRR] 11.8, 95% CI 10.0-14.0) and Pacific Islander (aRR 23.6, 95% CI 19.9-27.9) ethnicity compared with persons of European/other ethnicity. We also noted higher rates of initial RHD hospitalization for Māori (aRR 3.2, 95% CI 2.9-3.5) and Pacific Islander (aRR 4.6, 95% CI 4.2-5.1) groups and RHD deaths among these groups (Māori aRR 12.3, 95% CI 10.3-14.6, and Pacific Islanders aRR 11.2, 95% CI 9.1-13.8). Rates also were higher in socioeconomically disadvantaged neighborhoods. To curb high rates of ARF and RHD, New Zealand must address increasing social and ethnic inequalities.

Adherence to Secondary Prophylaxis for Acute Rheumatic Fever and Rheumatic Heart Disease: A Systematic Review.

Project description:BackgroundOptimal delivery of regular benzathine penicillin G (BPG) injections prescribed as secondary prophylaxis for acute rheumatic fever (ARF) and rheumatic heart disease (RHD) is vital to preventing disease morbidity and cardiac sequelae in affected pediatric and young adult populations. However, poor uptake of secondary prophylaxis remains a significant challenge to ARF/RHD control programs.ObjectiveIn order to facilitate better understanding of this challenge and thereby identify means to improve service delivery, this systematic literature review explored rates of adherence and factors associated with adherence to secondary prophylaxis for ARF and RHD worldwide.MethodsMEDLINE was searched for relevant primary studies published in the English language from 1994-2014, and a search of reference lists of eligible articles was performed. The methodological quality of included studies was evaluated using a modified assessment tool.ResultsTwenty studies were included in the review. There was a range of adherence to varying regimens of secondary prophylaxis reported globally, and a number of patient demographic, clinical, socio-cultural and health care service delivery factors associated with adherence to secondary prophylaxis were identified.ConclusionInsights into factors associated with lower and higher adherence to secondary prophylaxis may be utilized to facilitate improved delivery of secondary prophylaxis for ARF and RHD. Strategies may include ensuring an effective active recall system, providing holistic care, involving community health workers and delivering ARF/RHD health education.

Recent Advances in the Rheumatic Fever and Rheumatic Heart Disease Continuum.

Project description: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.

Rheumatic valvular heart disease treated with traditional Chinese medicine: A case report.

Project description:BackgroundRheumatic heart disease (RHD) is an autoimmune disease that leads to irreversible valve damage and heart failure. Surgery is an effective treatment; however, it is invasive and carries risks, restricting its broad application. Therefore, it is essential to find alternative nonsurgical treatments for RHD.Case summaryA 57-year-old woman was assessed with cardiac color Doppler ultrasound, left heart function tests, and tissue Doppler imaging evaluation at Zhongshan Hospital of Fudan University. The results showed mild mitral valve stenosis with mild to moderate mitral and aortic regurgitation, confirming a diagnosis of rheumatic valve disease. After her symptoms became severe, with frequent ventricular tachycardia and supraventricular tachycardia > 200 beats per minute, her physicians recommended surgery. During a 10-day preoperative waiting period, the patient asked to be treated with traditional Chinese medicine. After 1 week of this treatment, her symptoms improved significantly, including resolution of the ventricular tachycardia, and the surgery was postponed pending further follow-up. At 3 -month follow-up, color Doppler ultrasound showed mild mitral valve stenosis with mild mitral and aortic regurgitation. Therefore, it was determined that no surgical treatment was required.ConclusionTraditional Chinese medicine treatment effectively relieves symptoms of RHD, particularly mitral valve stenosis and mitral and aortic regurgitation.
