Guidelines for the secondary prevention of rheumatic heart disease: Endorsed by Saudi Pediatric Infectious Diseases Society (SPIDS)

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

Background

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.

Methods

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.

Results

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)].

Conclusion

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.

Trends in Rheumatic Heart Disease-Related Mortality in the United States from 1999 to 2020

There is a lack of mortality data on rheumatic heart disease (RHD) in the United States (US). In light of this, a retrospective analysis was conducted to investigate the temporal, sex-based, racial, and regional trends in RHD-related mortality in the US, ranging from 1999 to 2020. The Center for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC-WONDER) dataset was analyzed, where crude and age-adjusted mortality rates (AAMR) were identified, along with annual percentage changes (APCs) determined by Joinpoint regression. Through the period of 1999 to 2020, there were 141,137 RHD-related deaths reported, with a marginal decline from 4.05/100,000 in 1999 to 3.12/100,000 in 2020. However, the recent rise in AAMR from 2017 to 2020 has created a source of concern (APC: 6.62 [95% CI, 3.19-8.72]). Similar trends were observed in the Black or African American race from 2017 to 2020 (APC: 10.58 [95% CI, 6.29-17.80]). Moreover, the highest percentage change from 2018 to 2020 was observed in residents of large metropolitan areas (APC: 7.6 [95% CI, 2.8-10.5]). A prominent disparity was observed among states, with values ranging from 1.74/100,000 in Louisiana to 5.27/100,000 in Vermont. States within the top 90th percentile of RHD-related deaths included Alaska, Minnesota, Washington, Wyoming, and Vermont. In conclusion, it is imperative to delve deeper into the evidently rising trends of RHD-related mortality and outline the possible sources of social determinants within US healthcare in order to provide equal and quality medical care throughout the nation.

Secondary Prophylaxis Among First Nations People With Acute Rheumatic Fever in Australia: An Integrative Review

INTRODUCTION

The prevalence of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) among Australia's First Nations populations are some of the highest in the world, accounting for 95% of the 2,244 ARF notifications between 2015 and 2019 in Australia. A key issue in treating ARF is long-term secondary prophylaxis, yet only one in five patients received treatment in 2019. This review identifies barriers to secondary prophylaxis of ARF in Australia's First Nations people.

METHODS

An integrative review was undertaken utilizing PubMed, CINAHL, ProQuest, and Wiley Online. Joanna Briggs Institute critical appraisal tools were used, followed by thematic analysis.

RESULTS

The key themes uncovered included: issues with database and recall systems, patient/family characteristics, service delivery location and site, pain of injection, education (including language barriers), and patient-clinician relationship.

CONCLUSIONS

A national RHD register, change in operation model, improved pain management, improved education, and need for consistent personnel is suggested.

Diagnosis, management, and prevention of acute rheumatic fever in the United States

ABSTRACT

Acute rheumatic fever is a multisystem autoimmune disease caused by infection with group A streptococcus. The condition most commonly affects children ages 5 to 14 years who are from low-income populations. The diagnosis is clinical; however, the 2015 Jones Criteria can help support it. Acute rheumatic fever poses a significant health risk secondary to rheumatic heart disease. Although acute rheumatic fever is rare in the United States, outbreaks still occur, and certain populations continue to be at increased risk. This article describes how to identify acute rheumatic fever and provides prompt management and prevention strategies to reduce patient risk for lifelong complications.

Predictors of rheumatic fever in sore throat patients: a systematic review and meta-analysis

Background

Concerns about rheumatic fever (RF) drive antibiotic prescriptions for sore throat (ST) in endemic areas. Better guidance is needed on which patients are likely to develop RF in order to avoid misuse and overuse of antibiotics. Our aim was to identify predictive factors for RF in ST patients.

Methods

Multiple databases were searched to identify cohort, case–control, cross-sectional or randomised controlled trials that measured RF incidence in ST patients. An inverse variance random effects model was used to pool the data and calculate odds ratios (ORs).

Results

Seven studies with a total of 6890 participants were included: three RCTs and four observational studies. Factors significantly associated with RF development following ST were positive group A streptococcal (GAS) swab (OR 1.74 [95% confidence interval {CI} 1.13 to 2.69]), previous RF history (OR 13.22 [95% CI 4.86 to 35.93]) and a cardiac murmur (OR 3.55 [95% CI 1.81 to 6.94]). Many potential risk factors were not reported in any of the included studies, highlighting important evidence gaps.

Conclusions

ST patients in endemic areas with a positive GAS swab, previous RF history and a cardiac murmur are at increased risk of developing RF. This review identifies vital gaps in our knowledge of factors predicting RF development in ST patients. Further research is needed to develop better clinical prediction tools and rationalise antibiotic use for ST.

Assessing the Quality of Clinical Practice Guidelines in the Middle East and North Africa (MENA) Region: A Systematic Review

Aim

Clinical practice guidelines (CPGs) have progressively become a popular tool for making optimal clinical decisions. The literature shows that the poor quality of CPGs can form a barrier against adhering to them, resulting in a suboptimal level of healthcare. The objective of this systematic review is to evaluate the quality of CPGs in the Middle East and North Africa (MENA) region using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) Instrument.

Methods

The authors searched in the MEDLINE and EMBASE databases through the Ovid interface on May 25, 2019. Keywords relating to CPGs and MENA countries were combined using Boolean search operators. The search was not limited to specific diseases. The quality of guidelines was appraised by two reviewers independently using the AGREE II Instrument. Discrepancies within a group were resolved through the involvement of a principle investigator.

Results

A total of 61 CPGs were appraised. These guidelines were mainly from Saudi Arabia, and the most covered disease topic was cancer. Among the six domains of the AGREE II Instrument, CPGs scored the highest on clarity of presentation (mean 82%), while the lowest score was granted to the rigor of development domain (mean 28%). This indicates substantial deficiencies in reporting the developmental processes of CPGs and the resources used for the synthesis of evidence.

Conclusion

From this review, it was found that the number of retrieved guidelines published in the MENA region is limited considering the large geographical area of the MENA region. The main domains that have higher quality scores were clarity of presentation and scope and purpose, whereas domains with the lowest scores were rigor of development and applicability. The authors’ findings will help policymakers identify areas for improvement in CPGs, which can lead them to implement strategies such as the training of individuals and recruitment of international experts to ultimately develop high-quality CPGs.

Acute rheumatic fever diagnosis and management: Review of the global implications of the new revised diagnostic criteria with a focus on Saudi Arabia

Rheumatic fever (RF) is a common cause of acquired heart disease in children worldwide. It is a delayed, nonsuppurative, autoimmune phenomenon following pharyngitis, impetigo, or scarlet fever caused by group A β-hemolytic streptococcal (GAS) infection. RF diagnosis is clinical and based on revised Jones criteria. The first version of the criteria was developed by T. Duckett Jones in 1944, then subsequently revised by the American Heart Association (AHA) in 1992 and 2015. However, RF remains a diagnostic challenge for clinicians because of the lack of specific clinical or laboratory findings. As a result, it has been difficult for some time to maintain a balance between over- and underdiagnosis of RF cases. The Jones criteria were revised in 2015 by the AHA, and the main modifications were as follows: the population was subdivided into moderate- to high-risk and low risk; the concept of subclinical carditis was introduced; and monoarthritis was included as a feature of musculoskeletal inflammation in the moderate- to high-risk population. This review will highlight the major changes in the AHA 2015 revised Jones criteria for pediatricians and general practitioners.
