The clinical characteristics of adults with rheumatic heart disease in Yangon, Myanmar: An observational study

Monoarthritis as the initial presentation of acute rheumatic fever in Iran: A single-center retrospective cross-sectional study

Background

In Iran, there is a lack of information and studies on acute rheumatic fever (ARF), a global health issue. The limited understanding of ARF's prevalence and primary clinical symptoms has led to confusion. This research investigates the characteristics of children aged 3-17 years who experience ARF with monoarthritis as their initial symptom.

Methods

A retrospective evaluation of medical records of children diagnosed with ARF was conducted. The study aimed to determine the prevalence of monoarthritis as the first manifestation of ARF and its association with age, gender, family history, and cardiac involvement. Categorical variables were analyzed using the chi-square test with a significance level of < 0.05 and a confidence interval of 95%, using SPSS software (Version 23).

Results

The study included 62 patients with ARF, comprising 41 (66.1%) boys with an average age of 8.48±3.27 years. Among these patients, 12 exhibited cardiac involvement according to the revised Jones criteria, with 5 clinical carditis and 7 cases of subclinical carditis. Monoarthritis was the initial symptom in seven patients (11.29%); five (71.4%) also had carditis. There was a significant association (p<0.001) between monoarthritis and carditis.

Conclusion

The study concludes that monoarthritis may be an early sign of ARF in children and correlates significantly with cardiac involvement. However, more extensive research with more significant participant numbers is necessary to understand ARF in Iran comprehensively. A thorough cardiac examination is also crucial for patients with ARF and monoarthritis.

Statement from the Asia Summit: Current state of arrhythmia care in Asia

On May 27, 2022, the Asia Pacific Heart Rhythm Society and the Heart Rhythm Society convened a meeting of leaders from different professional societies of healthcare providers committed to arrhythmia care from the Asia Pacific region. The overriding goals of the meeting were to discuss clinical and health policy issues that face each country for providing care for patients with electrophysiologic issues, share experiences and best practices, and discuss potential future solutions. Participants were asked to address a series of questions in preparation for the meeting. The format of the meeting was a series of individual country reports presented by the leaders from each of the professional societies followed by open discussion. The recorded presentations from the Asia Summit can be accessed at https://www.heartrhythm365.org/URL/asiasummit-22. Three major themes arose from the discussion. First, the major clinical problems faced by different countries vary. Although atrial fibrillation is common throughout the region, the most important issues also include more general issues such as hypertension, rheumatic heart disease, tobacco abuse, and management of potentially life-threatening problems such as sudden cardiac arrest or profound bradycardia. Second, there is significant variability in the access to advanced arrhythmia care throughout the region due to differences in workforce availability, resources, drug availability, and national health policies. Third, collaboration in the area already occurs between individual countries, but no systematic regional method for working together is present.

Pregnancy risk and contraception among reproductive-age women with rheumatic heart disease attending care at a tertiary cardiac center in Tanzania: a hospital-based cross-sectional study

BACKGROUND

Rheumatic heart disease (RHD) remains prevalent in the developing world and reproductive-age women are disproportionately affected. It is among the common est cardiac diseases during pregnancy and is associated with poor pregnancy outcomes. Despite its importance among reproductive-age women, there are no local studies that characterize the clinical characteristics, risk of poor pregnancy outcomes and contraception which represents one effective way to prevent unplanned pregnancies in this population.

METHODS

This was a hospital-based descriptive cross-sectional study. Non-pregnant reproductive-age women with echocardiographically diagnosed RHD were consecutively recruited from in- and out-patients units of the Jakaya Kikwete Cardiac Institute (JKCI). A clinical research form was used to gather socio-demographic, clinical characteristics, contraception status and echocardiographic information. The maternal/pregnancy risk class was determined using the modified World Health Organization (WHO) classification of maternal risk.

RESULTS

Two hundred thirty-eight women of reproductive age with RHD were recruited. The median age (range) was 36 years (15-49). Two-thirds were dyspneic on moderate exertion and 17.2% had New York Heart Association class IV heart failure. A quarter had atrial fibrillation/flutter. On echocardiography, mitral regurgitation was the most common valvular lesion (68.1%), followed by mitral stenosis (66.8%), and 12.2% of participants had reduced left ventricular ejection fraction. Two-thirds (66%) had a high pregnancy risk (class IV) based on the modified WHO classification system. The proportion of participants using contraception was 7.1% and common methods were: bilateral tubal ligation 5 of 17 (29.4%) and hormonal implant (4 of 17). The most common reason for the choice of a method was safety, 10 out of 17 (58.8%).

CONCLUSION

The majority of women of reproductive age with RHD in our hospital cohort are at the highest pregnancy risk based on the modified WHO classification and a very small proportion of them are on contraception. These results call for action among clinicians to offer counselling to these patients, educating them on their risk and offering appropriate contraception advice while waiting for definitive interventions.

Health Related Quality of Life and Associated Factors Among Adult Patients with Rheumatic Heart Disease Patients in Ethiopia

Background

Quality of life (QOL) is defined as "individuals" perceptions of their position in life. Rheumatic heart disease (RHD) is a consequence of severe, single, or recurrent bouts of acute rheumatic fever. To improve overall patient outcomes, there is currently a greater emphasis on assessing the QOL of these patients. The purpose of this study is to assess the QOL of adult RHD patients who had followed up at St Peter and Tikur Anbessa Hospital, Ethiopia.

Methods

An institutional-based cross-sectional study done at St Peter and Tikur Anbessa Hospital, Ethiopia from March 1-June 30/2021 in adult RHD patients. The sample size was 297. Socio-demographic and clinical data were collected using a structured questionnaire. The Amharic version of Short form-36 (SF-36) was used to assess the QOL. A logistic regression model was used to identify associated factors.

Results

The study included 297 patients. The majority are female (71%), and half of them are aged between 18-30 years of age. Of the patiends, 81.1% had no comorbidity, and 15.8% had interventions. RHD affects all domains and summary scores of short form 36 QOL parameters compared to normative values. Age, marital status, place of residence, presence of comorbidity, number of medications, and whether an intervention was done are associated with the QOL of these patients.

Conclusion

RHD patients had poor QOL assessed by SF-36. It affects all domains and summary score of short form 36 QOL parameters. Old age, divorce, living in rural areas, associated comorbid conditions, and no intervention done are associated with poor QOL. Identification and treating comorbid conditions and intervention may improve QOL.

The temporospatial epidemiology of rheumatic heart disease in Far North Queensland, tropical Australia 1997-2017; impact of socioeconomic status on disease burden, severity and access to care

Background

The incidence of rheumatic heart disease (RHD) among Indigenous Australians remains one of the highest in the world. Many studies have highlighted the relationship between the social determinants of health and RHD, but few have used registry data to link socioeconomic disadvantage to the delivery of patient care and long-term outcomes.

Methods

A retrospective study of individuals living with RHD in Far North Queensland (FNQ), Australia between 1997 and 2017. Patients were identified using the Queensland state RHD register. The Socio-Economic Indexes for Areas (SEIFA) Score–a measure of socioeconomic disadvantage–was correlated with RHD prevalence, disease severity and measures of RHD care.

Results

Of the 686 individuals, 622 (90.7%) were Indigenous Australians. RHD incidence increased in the region from 4.7/100,000/year in 1997 to 49.4/100,000/year in 2017 (p<0.001). In 2017, the prevalence of RHD was 12/1000 in the Indigenous population and 2/1000 in the non-Indigenous population (p<0.001). There was an inverse correlation between an area’s SEIFA score and its RHD prevalence (rho = -0.77, p = 0.005).

249 (36.2%) individuals in the cohort had 593 RHD-related hospitalisations; the number of RHD-related hospitalisations increased during the study period (p<0.001). In 2017, 293 (42.7%) patients met criteria for secondary prophylaxis, but only 73 (24.9%) had good adherence. Overall, 119/686 (17.3%) required valve surgery; the number of individuals having surgery increased over the study period (p = 0.02).

During the study 39/686 (5.7%) died. Non-Indigenous patients were more likely to die than Indigenous patients (9/64 (14%) versus 30/622 (5%), p = 0.002), but Indigenous patients died at a younger age (median (IQR): 52 (35–67) versus 73 (62–77) p = 0.013). RHD-related deaths occurred at a younger age in Indigenous individuals than non-Indigenous individuals (median (IQR) age: 29 (12–58) versus 77 (64–78), p = 0.007).

Conclusions

The incidence of RHD, RHD-related hospitalisations and RHD-related surgery continues to rise in FNQ. Whilst this is partly explained by increased disease recognition and improved delivery of care, the burden of RHD remains unacceptably high and is disproportionately borne by the socioeconomically disadvantaged Indigenous population.

Rheumatic heart disease (RHD), a disease of poverty and disadvantage, is almost completely preventable. It is now extremely rare in wealthy countries, but in Far North Queensland in tropical Australia, the incidence of RHD, RHD-related hospitalisations and RHD-related surgery is continuing to rise, with the burden of disease borne almost entirely by the region’s Indigenous population. While the increasing incidence of RHD and its complications may be partly explained by improvements in local service delivery, the disease remains inextricably linked to socioeconomic disadvantage. In this study, not only were patients living in socioeconomically disadvantaged areas more likely to have RHD, but they were also paradoxically less likely to receive valve surgery. The current local model of care—which is centralised, medical and emphasises disease monitoring and secondary prophylaxis—appears to be having a limited impact on morbidity. Strategies must evolve—in partnership with Indigenous communities—to have a greater focus on disease prevention by addressing the personal, community and environmental factors that increase the risk of the disease. This is likely to not only reduce the incidence of RHD, but will also tend to reduce the burden of the many other diseases that result from socioeconomic disadvantage and that disproportionately affect Indigenous Australians.

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.

Sequential Helicobacter pylori eradication therapy in Myanmar; a randomized clinical trial of efficacy and tolerability

BACKGROUND AND AIM

There is little published research to examine the best approach to the management of Helicobacter pylori in Myanmar. This study aimed to determine the relative efficacy and tolerability of sequential eradication therapy compared to Myanmar's current recommendation of a concomitant four drug regimen.

METHODS

Patients were screened for H. pylori using monoclonal Stool Antigen Testing (SAT). Those testing positive were randomized 1:1 to receive receive Myanmar's first-line regimen of 14 days of concomitant rabeprazole, clarithromycin, amoxycillin and tinidazole (140 pills, cost US$23) or 10 days of sequential rabeprazole, clarithromycin, amoxycillin and tinidazole (60 pills, cost US$10). Adherence and adverse effects were recorded, and the efficacy of the regimens assessed with repeat SAT.

RESULTS

Of the 1011 patients screened for H. pylori infection, 313 (31%) tested positive. There was no statistical difference in the cure rates of the two regimens in either intention-to-treat: 128/157 (82%; 95% confidence interval (CI): 75-87%) receiving sequential therapy versus 123/156 (79%; 95% CI: 72-85%) receiving concomitant therapy (P = 0.55) or per-protocol analysis: 125/131 (95%; 95% CI: 90-98) receiving sequential therapy versus 121/130 (93%; 95% CI: 87-96) receiving concomitant therapy (P = 0.42). Side effects of therapy were reported in 54/157 (47%) patients taking sequential therapy compared with 62/156 (53%) taking concomitant therapy, but this difference did not reach statistical significance (P = 0.33).

CONCLUSIONS

In this high-burden, resource-poor setting, less expensive sequential therapy was as effective and as well tolerated as the currently recommended concomitant four drug regimen for eradication of H. pylori.

A glimpse of hope: cardiac surgery in low- and middle-income countries (LMICs)

Currently, more than five times more people live in low- and middle-income countries (LMICs) than in high-income countries (HICs). As such, the downward trend in cardiac surgical needs in HICs reflects only the situation of one sixth of the world population while the vast majority living in LMICs has still no or limited access to life saving heart operations. In these countries, rheumatic heart disease (RHD) still accounts for a significant proportion of cardiac surgical needs. In low- and lower-middle income countries it remains the single most common cardiovascular disease in young adult and adolescent patients in need of heart surgery outweighing other indications such as congenital cardiac defects almost 4-fold. Compared to HICs with their predominance of calcific aortic stenosis in the elderly mitral valve surgery is required in >90% of the largely young patients with RHD in low-income countries (LICs) and still in 70% of the often middle aged patients in middle-income countries (MICs). Although recent government initiatives in LICs led to the establishment of local, independent cardiac surgical services gradually replacing fly-in missions, these centers still only cover less than 2% of the needs of their populations. In MICs, cardiac surgical needs continually grow with the emergence of degenerative diseases. As such, in spite of the concomitant growth of cardiac surgical capacity, significantly less than half the estimated patients in need have access. Capacities in LICs range from 0.5 to 7 cardiac operations/million population; 100-481/million in MICs and >1,200/million in HICs such as the USA and Germany. While a new level of awareness of the scope and magnitude of the problem has begun to emerge in LICs and the establishment of local cardiac surgical capacity has given rise to a glimpse of hope, the challenges of expanding these fledgling services to a significant proportion of the population still seem insurmountable. Challenges in MICs are on the other hand the widening gap between private cardiac medicine for the affluent few and overwhelmed public services for the many and the rural urban divide with the underappreciation of the ongoing dominance of RHD in the rural and indigent population on the other. Overshadowing all LMICs is the low level of valve-repair skills associated with insufficient cardiac surgical capacity and the unavailability of suitable replacement valves which address the young age of the patients and the difficulties of anticoagulation in a socioeconomic environment distinctly different from the elderly patients of HICs.

Profile of newly diagnosed adult patients with rheumatic heart disease in sub-Himalayan region - A 5-year analysis

Introduction:

Rheumatic heart disease (RHD) is one of the leading acquired causes of cardiac diseases affecting the young population, worldwide.

Aims and Objectives:

The primary objective was to study the prevalence, profile, and complications of patients with RHD in a tertiary care hospital of Uttarakhand. The secondary objective was to assess the demographic and clinical parameters of patients with RHDs.

Materials and Methods:

All adult patients above the age of 18 years, diagnosed with RHD, over a period of 5 years from July 2008 to June 2013 were enrolled in the study. Detailed clinical data of the patients were obtained retrospectively from the hospital record section. Information regarding prevalence of RHD, profile, and complications of patients with RHD was collected from patient's case sheet and tabulated.

Results:

In all, 1001 patients age more than 18 years with RHD presented to either medical or cardiology outpatient departments over a period of 5 years from July 11 to June 2018. Mitral regurgitation (n = 610, 61.9%) was the most common RHD. Females (n = 538, 53%) outnumbered males (n = 464, 46.2%). Heart failure (n = 353, 35.1%), severe pulmonary arterial hypertension (n = 118, 11.7%), and atrial fibrillation (n = 212, 21.1%) were common complications. A total of 75 (7.4%) patients presented with bacterial endocarditis, whereas 32 (3.2%) patients succumbed to death due to RHD.
