Assessing the knowledge, attitude, and practice of frontline physicians in Egyptian university hospitals regarding pharyngitis and acute rheumatic fever: a cross-sectional study that calls for action

BackgroundAcute 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.MethodsWe 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.ResultsThe 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%).ConclusionsDespite 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.

Eliminate all risks: A call to reexamine the link between canine scabies and rheumatic heart disease.

Rheumatic heart disease (RHD) and acute rheumatic fever (ARF) disproportionately affect individuals in low-resource settings. ARF is attributed to an immune response to Group A Streptococcus (GAS) following GAS pharyngitis and potentially GAS impetigo in which infection can be initiated by scabies infestation. The burden of ARF and RHD in Aboriginal and Torres Strait Islander people in Australia is among the highest globally. Following recent calls to include dog management programs in ARF and RHD prevention programs, we believe it is timely to assess the evidence for this, particularly since previous recommendations excluded resources to prevent zoonotic canine scabies. While phylogenetic analyses have suggested that the Sarcoptes mite is host specific, they have differed in interpretation of the strength of their findings regarding species cross-over and the need for canine scabies control to prevent human itch. Given that there is also indication from case reports that canine scabies leads to human itch, we propose that further investigation of the potential burden of zoonotic canine scabies and intervention trials of canine scabies prevention on the incidence of impetigo are warranted. Considering the devastating impacts of ARF and RHD, evidence is required to support policy to eliminate all risk factors.

Adherence to penicillin treatment is essential for effective secondary prevention of rheumatic heart disease: a systematic review and meta-analysis.

Penicillin is essential for secondary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD). However, the incidences of ARF recurrence and RHD progression remain high, particularly in endemic countries. This meta-analysis evaluated the effectiveness of penicillin adherence in secondary prevention of ARF recurrence and RHD progression. The authors included original articles employing an observational study design in which the study population included patients with ARF or RHD and documented adherence to secondary prophylaxis with penicillin for secondary prevention. Systematic searches of the PubMed, Scopus, and Cochrane databases were performed. Moreover, the authors also conducted a snowballing literature search from Europe PMC to expand the included studies. The quality of each study was assessed using the National Institute of Health Quality Assessment Tool. The statistical analyses were conducted using Review Manager 5.4.1 software developed by Cochrane. In addition, the authors utilized pooled odds ratios (ORs) to compare the adherence techniques. A total of 310 studies were identified, of which 57 full-text articles were assessed for eligibility. The authors included six studies with 1364 patients for the qualitative synthesis and meta-analysis. Good adherence to penicillin for the secondary prophylaxis of ARF and RHD, significantly reduced the odds of ARF recurrence or RHD progression by up to 71% compared to that associated with poor adherence [pooled OR 0.29 (0.21-0.40); I²=0% (p=0.56); Z=7.64 (p <0.00001)]. Good adherence to penicillin for secondary prophylaxis in patients with ARF or RHD is essential for reducing the risk of ARF recurrence or RHD progression.

Associations of &lt;i&gt;TLR&lt;/i&gt; gene polymorphism with the risk of rheumatic heart disease

Aim of the study was to investigate the associations between TLR gene polymorphism and the risk of rheumatic heart disease (RHD).Material and methods. 251 RHD patients (190 females and 61 males) and 300 healthy donors (190 females and 110 males), whose age was 57 [29; 77] and 53 [21; 80] years (median [lower quartile; upper quartile]), respectively, were recruited in the presented study. Eight polymorphic variants in the TLR gene were genotyped by realtime PCR.Results. We found no statistically significant differences in the frequency of eight polymorphic variants in the TLR1, TLR2, TLR4 and TLR6 genes in the general group of patients. Stratification by gender and age showed that the frequency of the C/C genotype of the TLR1 gene (rs5743551) was increased in females with RHD (11.6 %) compared to the control group (5.3 %); a risk effect was determined for recessive inheritance patterns (odds ratio 2.43, 95 % confidence interval 1.07–5.52, p = 0.029). Moreover, the combination of polymorphic variants TLR2 (rs5743708) – TLR4 (rs4689791) – TLR1 (rs5743551) – TLR2 (rs3804099) showed the greatest significance in RHD risk.Conclusions. Future research on the different populations will allow to discover the general patterns of RHD pathogenesis, which will finally lead to the establishment of therapeutic targets for treatment of streptococcal infection and RHD prevention.

Effectivity and adherence of secondary prevention on clinical outcome of rheumatic heart disease in high-burden setting: a systematic review and meta-analysis

Abstract Background Rheumatic heart disease (RHD) is often diagnosed late in low-resource settings due to limited health-seeking behavior and varied presentations. Optimal delivery of regular antibiotics prescribed as secondary prevention is vital to preventing disease progression. However, poor adherence of secondary prevention remains a significant challenge to these populations. Objective To assess the efficacy and adherence of patients to secondary prevention of rheumatic heart disease. Methods This systematic review and meta-analysis was carried out according to the PRISMA statement. Literature search was performed on four databases using keywords "Rheumatic heart disease", "secondary prevention", and their synonyms. Adherence and disease progression were the primary outcome. The overall proportion was estimated with R software (version 4.1.3) using a random-effects model of proportional meta-analysis. Results Thirteen studies were included in this study. Benzathine Penicillin G (BPG) injection every 4 weeks was the most common secondary prophylaxis regimen used. In 2052 patients, only 46% (27-66%) patients received &amp;gt;80% BPG prophylaxis injection. The effectiveness of secondary prophylaxis was powerful, evidenced by only 7% (2-12%) patients having disease progression of rheumatic heart disease. Conclusions BPG was found to be effective in the secondary prevention of rheumatic heart disease. Nonetheless, patient adherence to injection remains extremely low. Methods to improve patient adherence are imminently required.Figure 1Figure 2

Sub-clinical rheumatic heart disease (RHD) detected by hand-held echocardiogram in children participating in a school-based RHD prevention program in Tanzania

BackgroundRheumatic Heart Disease (RHD) continues to cause suffering and premature deaths in many sub-Saharan Africa (SSA) countries, where the disease is still endemic. RHD is largely preventable and determining its community burden is an important critical step in any RHD prevention program.MethodsWe conducted a cross-sectional study of 5–16 years old pupils from 11 primary schools participating in an RHD prevention program in 4 districts in Tanzania, between 2018 and 2019. At the school, all children were invited to participate after receiving consent from their parents/guardians. Participating children filled a questionnaire and were auscultated for cardiac murmurs. Echocardiographic screening was done by two experienced cardiologists, using a hand-held machine (V-Scan, GE®). All positive screening tests were stored for further examination by the same two cardiologists to reach to a consensus of definite, borderline or no RHD, using a modified World Heart Federation (WHF) criterion.ResultsOf the 6895 children invited, 4738 (68.7%) were screened and 4436 (64.3%) had complete data. The mean (SD) age was 10.04 (2.43) years, and 2422 (54.6%) were girls. Fifty three (1.2%) children were found to have a murmur. The proportion of children with trace or mild valvular regurgitation, sub-valvular/chordal thickening and valvular thickening/deformity were 8.3%, 1.3%, and 1.0%, respectively. Sub-clinical RHD was found in 95 children (59 definite and 36 borderline), giving a prevalence of 2.1%, [95% CI 1.7% – 2.6%]. Sub-clinical RHD was independently associated with female sex (aOR 1.83, 95% CI 1.18–2.85, p = 0.007), older age groups (aOR 1.73, 95% CI 1.10–2.72, p = 0.018 for age group 11–14 years; and aOR 3.02 95% CI 1.01–9.05, p = 0.048 for age group 15–16 years), as well as presence of a cardiac murmur, aOR 5.63 95% CI 2.31–13.69, p < 0.0001. None of the studied socio- or economic factors was associated with the presence of sub-clinical RHD in this study.ConclusionThe prevalence of sub-clinical RHD among primary school children in Tanzania is 2.1%, similar to previous reports in SSA. Efforts to prevent and control RHD in our communities are highly warranted.

Evaluating efficiency and equity of prevention and control strategies for rheumatic fever and rheumatic heart disease in India: an extended cost-effectiveness analysis

There is a dearth of evidence on the cost-effectiveness of a combination of population-based primary, secondary, and tertiary prevention and control strategies for rheumatic fever and rheumatic heart disease. The present analysis evaluated the cost-effectiveness and distributional effect of primary, secondary, and tertiary interventions and their combinations for the prevention and control of rheumatic fever and rheumatic heart disease in India. A Markov model was constructed to estimate the lifetime costs and consequences among a hypothetical cohort of 5-year-old healthy children. Both health system costs and out-of-pocket expenditure (OOPE) were included. OOPE and health-related quality-of-life were assessed by interviewing 702 patients enrolled in a population-based rheumatic fever and rheumatic heart disease registry in India. Health consequences were measured in terms of life-years and quality-adjusted life-years (QALY) gained. Furthermore, an extended cost-effectiveness analysis was undertaken to assess the costs and outcomes across different wealth quartiles. All future costs and consequences were discounted at an annual rate of 3%. A combination of secondary and tertiary prevention strategies, which had an incremental cost of ₹23 051 (US$30) per QALY gained, was the most cost-effective strategy for the prevention and control of rheumatic fever and rheumatic heart disease in India. The number of rheumatic heart disease cases prevented among the population belonging to the poorest quartile (four cases per 1000) was four times higher than the richest quartile (one per 1000). Similarly, the reduction in OOPE after the intervention was higher among the poorest income group (29·8%) than among the richest income group (27·0%). The combined secondary and tertiary prevention and control strategy is the most cost-effective option for the management of rheumatic fever and rheumatic heart disease in India, and the benefits of public spending are likely to be accrued much more by those in the lowest income groups. The quantification of non-health gains provides strong evidence for informing policy decisions by efficient resource allocation on rheumatic fever and rheumatic heart disease prevention and control in India.

Knowledge, attitude, and practice regarding prevention of rheumatic heart disease among primary health-care workers in sokoto metropolis, Sokoto State, Nigeria.

Rheumatic heart disease (RHD) is the only preventable cardiovascular disease that still causes significant morbidity and mortality in low- and middle-income countries like Nigeria where it is classified as a neglected disease. The inciting agent causes pharyngitis often not properly treated. To study the knowledge and preventive practices of RHD amongst primary healthcare workers who are in contact with larger ratio of populace in order to recommend appropriate interventions. A cross-sectional study conducted among health workers in primary health centres in Sokoto metropolis. Multi-stage sampling technique was used to recruit the study participants. A structured questionnaire and focus group discussion guide was used to collect the information. Data was analysed using IBM SPSS version 25. Majority (109/182; 59.8%) had RHD inadequate knowledge of causes, risk factors and treatment of pharyngitis which predisposes to RHD. Only 49 (26.9%) of the respondents knew the name of the causative agent. The knowledge gap was related to length of training and attendance at a training (ꭓ2 = 8.38; P=0.015 & ꭓ2 = 7.92; P=0.004). Majority of the respondents with 168 out of 182 (92.3%) had positive attitude. Practice grading was adequate in only less than half of the respondents (88/182; 48.4%). Male gender and negative attitude were predictors of adequacy of preventive practices (aOR= 0.49; 95% C.I =0.267-0.929; P=0.03 & aOR= 3.87; 95% C.I =1.027-14.586; P=0.046). The health workers had inadequate knowledge and poor practice on prevention of rheumatic heart disease. It is necessary to upscale information available to them by medical specialists and upgrade their curriculum.

Adapted echocardiography screening methods for prevention of rheumatic heart disease in Sub-Saharan Africa: a systematic review

Echocardiography is the current gold standard used in diagnosing rheumatic heart disease and its associated sequelae, but utilization is currently limited in resource-poor settings. Decentralized diagnostic methods in these areas are crucial to improving cardiac health outcomes. A systematic review was undertaken to evaluate the diagnostic performance of adapted echocardiography screening methods in countries of sub-Saharan Africa. A literature search was conducted via the PubMed, Embase, and African Healthline databases. Studies were included in the review if they assessed the diagnostic accuracy of an adapted screening method as compared to the reference standard of hospital-based echocardiogram by trained cardiologists. Diagnostic performances of handheld echocardiography and task-shifting to non-physician roles, were assessed. For HAND techniques, the pooled sensitivity, specificity and diagnostic odds ratio was 81.2%, 91.7%, and 48.01% respectively. Task-shifting and simplified protocol diagnostic performance was also analyzed; pooled sensitivity, specificity and diagnostic OR was 74.8%, 89.5%, and 25.37% respectively. This review demonstrates strong specificity with moderate sensitivity among both methods of adapted screening. HAND methods using the standard prescribed WHO protocol had stronger diagnostic performance overall. These studies present a first step towards validating current echocardiographic screening criteria using hand-held machines and establishing training of non-physicians to conduct screening in low-resource settings.

Medical Treatment for Rheumatic Heart Disease: A Narrative Review.

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are rare in high-income countries; however, in Aotearoa New Zealand ARF and RHD disproportionately affect Indigenous Māori and Pacific Peoples. This narrative review explores the evidence regarding non-surgical management of patients with clinically significant valve disease or heart failure due to RHD. Medline, EMBASE and Scopus databases were searched, and additional publications were identified through cross-referencing. Included were 28 publications from 1980 onwards. Of the available interventions, improved anticoagulation management and a national RHD register could improve RHD outcomes in New Zealand. Where community pharmacy anticoagulant management services (CPAMS) are available good anticoagulation control can be achieved with a time in the therapeutic range (TTR) of more than 70%, which is above the internationally recommended level of 60%. The use of pharmacists in anticoagulation control is cost-effective, acceptable to patients, pharmacists, and primary care practitioners. There is a lack of local data available to fully assess other interventions; including optimal therapy for heart failure, equitable access to specialist RHD care, prevention, and management of endocarditis. As RHD continues to disproportionately affect Indigenous and minority groups, pro-equity tertiary prevention interventions should be fully evaluated to ensure they are reducing disease burden and improving outcomes in patients with RHD.

Secondary Prevention of Rheumatic Heart Disease in Nepal: Are We Going Backward?

A secondary level of prophylaxis has proven to be the most successful in Nepal, a country with an endemic rate of rheumatic heart disease, in combating the severe issues associated with rheumatic heart disease. The use of benzathine penicillin G in secondary prophylaxis of rheumatic heart disease, recommended by several guidelines, has been increasingly abandoned in Nepal due to a lack of national guidelines and the termination of the prior programs. The use of oral penicillin and alternative oral antibiotics, which are less effective in preventing the recurrence of acute rheumatic fever, is on the rise. Nepal urgently needs to develop new national guidelines and ensure their effective implementation in order to slow the increase in the number of rheumatic heart disease patients. In this article, we explore the limitations, challenges, and advantages of using the consensus-supported intramuscular benzathine penicillin G as the first-line drug for the secondary prevention of rheumatic heart disease.

Prevalence of Rheumatic Heart Disease among Children in Bangladesh

Aims: The prevalence of Rheumatic Heart Disease (RHD) is estimated to be higher in developing countries like Bangladesh than in developed countries, ranging from 24/1,000 to 0.3/1,000 respectively. There is no authentic national data since 2005 on prevalence of RHD in our country. Aim of this study is to find out present status of RHD among children in Bangladesh so that government can take further action to strengthen RHD prevention activity.&#x0D; Methods: A cross-sectional survey of children aged 5–15 years from 20 schools of urban non slum, urban slum and rural area was carried out by a team of cardiologists. Children were screened by clinical examination and diagnosis confirmed by echocardiography. Children who were not willing to enroll in the study and absent students at the day of data collection were excluded from the study. Ethical permission was taken from the institutional review board.&#x0D; Results: Total 5024 school children aged 5 to 15 years were screened for rheumatic heart disease. Male female ratio was 1.01. Prevalence of RF and RHD were 1.6/1000 and 0.8/1000 respectively. Prevalence of RHD was significantly higher among urban slum children (3.78/1000) than rural (0.33/1000) and urban non slum children (0.66/1000).&#x0D; Conclusion: The encouraging observation in our study is a decreasing trend of Rheumatic Fever and Rheumatic Heart Disease in Bangladesh

Evaluation of a nurse-led intervention to improve adherence to secondary prevention of rheumatic heart disease

Background/Aims Rheumatic heart disease is a major health concern in India. Secondary prevention following acute rheumatic fever can prevent disease escalation, but adherence rates are often low. This study evaluated whether a nurse-led intervention could effectively increase adherence rates to secondary prevention and reduce rheumatic symptoms in this patient group. Methods A total of 60 patients were randomly assigned to either an intervention or control group. The control group received standard treatment, while the intervention group received a 25-minute education session with a nurse, along with text message or phone call reminders before they were due for treatment. Participants also completed a rheumatic morbidity index scale survey over 12 months to record their symptoms. A two-way sample t-test was used to compare adherence rates and symptom incidence in both groups. Results Patients in the intervention group had significantly better adherence rates to their medication, receiving 11–17 of the total 18 injections over the 12-month period, compared to 6–12 in the control group. They were also less likely to experience symptoms of rheumatic heart disease or require emergency hospitalisation. Conclusions A nurse-led intervention is an effective method of reducing pressure on hospital services and increasing treatment adherence among patients receiving secondary prevention treatment for rheumatic heart disease.

Secondary prevention of rheumatic heart disease in Ethiopia: a multicenter study

BackgroundEthiopia has a high acute rheumatic fever (ARF) and rheumatic heart disease (RHD) prevalence, and to our knowledge, there are no data on the status of secondary prevention in children with RHD. This study describes the status of secondary RHD prevention.MethodsA multicenter, prospective study was performed on children aged 5–17 years with RHD in Ethiopia. Good adherence was defined as at least 80% completion of benzathine penicillin (BPG) or oral Amoxicillin within the previous year. The primary outcome measure was adherence to prophylaxis, expressed as a proportion. Socio-demographics, severity of RHD, and ARF recurrence were evaluated.ResultsA total of 337 children with a mean age of 12.9 ± 2.6 years were included. The majority (73%) had severe aortic/mitral disease. Participants were on BPG (80%) or Amoxicillin (20%) prophylaxis. Female sex (P = 0.04) use of BPG (0.03) and shorter mean duration of prophylaxis in months (48.5 ± 31.5 vs. 60.7 ± 33, respectively, P < 0.008) predicted good adherence. Running out of medications (35%), interrupted follow-up (27%), and the COVID-19 pandemic (26%) were the most common reasons for missing prophylaxis. Recurrence of ARF was higher in participants on Amoxicillin compared with BPG (40% vs. 16%, P < 0.001) and in those with poor adherence compared with good adherence (36.8% vs. 17.9%, respectively, P = 0.005). Type and duration of prophylaxis (OR 0.5, CI = 0.24, 0.9, P = 0.02; OR = 1.1, CI = 1.1, 1.2, P = 0.04, respectively), and sex (OR = 1.9, CI = 1.1, 3.4, P = 0.03) were independent predictors of poor adherence.ConclusionPoor adherence is prevalent in Ethiopian children living with RHD. Amoxicillin is a suboptimal option for prophylaxis as its use is associated with lower adherence and a higher rate of ARF recurrence.

Community Perspectives on Primary Prevention of Rheumatic Heart Disease in Uganda.

Background:Untreated streptococcal pharyngitis is a precursor to rheumatic heart disease (RHD) and remains a significant public health issue in many countries. Understanding local determinants of treatment-seeking behaviors can help tailor RHD prevention programs.Objective:We sought to elicit perceptions of pharyngitis and related healthcare use in a range of communities in Uganda.Methods:We conducted six focus group discussions (FGD) in three districts that were representative of the country’s socioeconomic and cultural heterogenetity. Participants were recruited from six villages (two per district), and FGDs were audio recorded, transcribed and translated into English. Deductive and inductive analysis of the transcripts was done via open axial and sequential coding, which informed development of clusters, themes and subthemes. We extracted quotations from the transcripts to illustrate these themes.Results:We identified nine key themes in three major domains: knowledge and perception of pharyngits, treatment practices, and barriers to uptake of formal public-sector healthcare services. Community awareness and understanding of the consequences of pharyngitis were low. Stated barriers to care were usually systemic in nature and included low overall confidence in the healthcare system and substantial costs associated with transportation and medications.Conclusion:The FGDs identified several approaches to shape community perceptions of pharyngitis and improve utilization of interventions to prevent RHD. In Uganda, information-education-communication interventions probably need to be combined with structural interventions that make formal public-sector healthcare more accessible to at-risk populations.

Rheumatic Heart Disease is Missing from the Global Health Agenda

Rheumatic heart disease (RHD) is a complication of untreated throat infection by Group A beta-hemolytic streptococcus with a high prevalence among socioeconomically disadvantaged populations. Despite its high incidence and prevalence, RHD prevention is not a priority in major global health discussions. The reasons for the apparent neglect are multifactorial, including underestimated morbidity and mortality burden, underappreciated economic burden, lack of public awareness, and lack of sustainable investment. In this review, we recommend multisectoral collaboration to tackle the burden of RHD by engaging the public, health experts, and policymakers; augmenting funding for clinical care; improving distribution channels for prophylaxis, and increasing research and innovation as critical interventions to save millions of people from preventable morbidity and mortality.
