Key Clinical Message: Concurrent recurrence of acute disseminated encephalomyelitis (ADEM) and poststreptococcal glomerulonephritis (PSGN) in a thalassemia intermedia patient is rare and underscores the complexity of autoimmune disorders. This case emphasizes the importance of considering ADEM in the differential diagnosis of children presenting with PSGN accompanied by neurological symptoms. Post‐streptococcal glomerulonephritis (PSGN) is a common group A streptococcal (GAS) infection sequela. The pathophysiology of PSGN involves immune complex deposition, with type 3 hypersensitivity reaction triggered by GAS. Certain neurological conditions may also arise following a GAS infection, possibly due to molecular mimicry in the brain, a pathophysiology similar to rheumatic fever, another common sequel of GAS infection. We present the case of a child with β‐thalassemia intermedia who exhibited the classic triad (edema, hypertension, hematuria) of PSGN along with neurological manifestations, including a low glasgow coma scale (GCS) score and seizures. Magnetic resonance imaging (MRI) of the brain indicated changes consistent with acute disseminated encephalomyelitis (ADEM). Initially treated with methylprednisolone, the patient eventually received intravenous immunoglobulin (IVIG) due to lack of response. The patient had a good outcome, with complete resolution of all symptoms and no residual neurological deficits. This case underscores the importance of considering ADEM in the differential diagnosis for patients presenting with neurological signs and symptoms following a recent throat infection with GAS. Furthermore, given the increased risk of infection in thalassemia, patients with thalassemia who have a throat infection and neurological symptoms should be evaluated for the possible presence of ADEM.

Aim: To describe the clinical profile of acute rheumatic fever (ARF) presentations to paediatric cardiology tertiary services in Western Australia (WA). Methods: A retrospective clinical audit of individuals with confirmed ARF referred to the only paediatric tertiary cardiac service in WA (1 January 1987 to 31 December 2020). Comparisons between inpatient, outpatient, remote and non‐remote groups were assessed. Results: Four hundred seventy‐one episodes of ARF in 457 individuals (235 male; median age = 8 years) met clinical criteria. The majority were Aboriginal and Torres Strait Islander children (91.2%), with 62.1% living in remote areas. The number of ARF and rheumatic heart disease (RHD) diagnoses per year increased from 1987 to 2017 with notable peaks in 2013 and 2017. The average annual incidence of tertiary‐referred ARF in WA of 4–15‐year‐olds from 1987 to 2020 was 4.96 per 100 000. ARF features included carditis (59.9%), chorea (31%), polyarthritis (30%) and polyarthralgia (24.2%). RHD was evident in 61.8% of cases and predominantly manifested as mitral regurgitation (55.7%). Thirty‐four children (7.4%) with severe RHD underwent valvular surgery. 12% had at least one recurrent ARF episode. Remote individuals had more than double the rate of recurrence compared to non‐remote individuals (P = 0.0058). Compared to non‐remote episodes, remote presentations had less polyarthritis (P = 0.0022) but greater proportions of raised ESR (P = 0.01), ASOT titres (P = 0.0073), erythema marginatum (P = 0.0218) and severe RHD (P = 0.0133). Conclusion: The high proportion of Aboriginal and Torres Strait Islander Australians affected by ARF/RHD in WA reflects the significant burden of disease within this population. Children from remote communities were more likely to present with concurrent severe RHD. Our study reinforces the persisting need to improve primary and secondary ARF initiatives in rural and remote communities. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Rheumatic heart disease is a preventable disease. Patients may not present with a typical history of sore throat and polyarthritis but may present with Sydenham's chorea. We should not rely completely on clinical findings to rule out carditis. Echocardiography should be done to rule out subclinical carditis. Sydenham's chorea is a major manifestation of rheumatic fever. It occurs primarily in children and is seen rarely after the age of 20 years. We describe a 16‐year‐old girl who presented with purposeless involuntary movements of her upper and lower limbs. Laboratory blood reports showed raised erythrocyte sedimentation rate and anti‐streptolysin O. 2D Doppler Echocardiography confirmed subclinical carditis, thickened mitral and aortic valve with mild mitral regurgitation. She was managed as Acute Rheumatic Fever with oral Phenoxymethyl penicillin and Carbamazepine. At the latest follow‐up interviewing the caregiver, the patient had no sequelae. Early diagnosis is key to preventing late consequences of acute rheumatic fever and rheumatic heart disease. Sydenham's chorea is a rare presentation of acute rheumatic fever. The absence of clinical carditis does not rule out carditis. [ABSTRACT FROM AUTHOR]

The article discusses the findings of a coroner's inquest into the deaths of three Aboriginal women from rheumatic heart disease (RHD) in the remote town of Doomadgee in Queensland, Australia. The inquest highlights the preventable nature of RHD and the inequitable burden experienced by Aboriginal and Torres Strait Islander peoples. The article presents recommendations for improving health service provision, including cultural safety, community engagement, data collection, and collaboration. It also addresses the issue of institutional racism within the healthcare system and calls for transformative action to achieve health equity for First Nations communities.

This article discusses the importance of early diagnosis, disease recognition, and secondary prevention for acute rheumatic fever (ARF) in Indigenous pediatric populations. It emphasizes the need for prompt management of endemic skin infections, such as impetigo and scabies, which can increase the risk of post-infectious complications including ARF. The article also addresses the social determinants of health for Indigenous Australians, including issues of overcrowding, poor nutrition and hygiene, distance from medical care, and cultural barriers to healthcare. It highlights the disproportionate impact of ARF on Indigenous Australians and the need to prioritize their health. The case report presented in the article further illustrates the challenges and considerations in diagnosing and managing ARF in Indigenous children. The article concludes by discussing the importance of holistic management, patient and family education, and addressing the underlying social determinants of health to reduce the prevalence of ARF in Indigenous communities. The article provides valuable resources and guidelines for healthcare professionals working with ARF and emphasizes the need for political commitment to achieve health equity and reduce the prevalence of diseases that represent disadvantage, like ARF.

Introduction: Cytomegalovirus (CMV) causes significant morbidity in solid organ transplant recipients (SOTR). Measuring cell‐mediated immunity (CMI) may inform the risk of CMV infection after antiviral prophylaxis and predict relapse after CMV treatment. Methods: We serially assessed CMV CMI using the QuantiFERON‐CMV assay (QF‐CMV; Qiagen, Germantown, MD) in two cohorts of SOTRs: during valganciclovir prophylaxis and during treatment of CMV viremia. Results of CMI were correlated with post‐prophylaxis CMV infection and post‐treatment relapse, respectively. Results: Only one (4.2%) of 24 CMV D+/R‐ patients demonstrated positive QF‐CMV by the end of valganciclovir prophylaxis. Four (16.6%) patients developed post‐prophylaxis CMV infection; all four had undetectable QF‐CMV at end of prophylaxis. Among 20 patients treated for CMV infection, 18 (90%) developed QF‐CMV levels >.2 IU/mL by end of antiviral treatment and none developed CMV relapse. In contrast, the single patient who relapsed after completing treatment had a CMV CMI <.2 IU/ml (p =.0036). Conclusion: Since CMV D+/R‐ SOTRs are unlikely to develop adequate CMV CMI while receiving valganciclovir prophylaxis, the utility of CMV CMI monitoring for risk stratification during time of prophylaxis had limited value. Conversely, CMV CMI testing may be a useful marker of the risk of CMV relapse after antiviral treatment. [ABSTRACT FROM AUTHOR]

Aim: Sydenham chorea is an immune‐mediated neuropsychiatric condition, and a major criterion for diagnosis of acute rheumatic fever (ARF). Children in remote Northern Australia experience disproportionately high rates of ARF, yet studies looking at the epidemiology, clinical presentation and management of Sydenham chorea are limited in this population. Methods: We conducted a retrospective case series from January 2002 to April 2022 of all paediatric patients aged ≤18 years admitted to Royal Darwin Hospital with Sydenham chorea. Cases were identified using the hospital's clinical coding system (ICD10). Medical records were reviewed and data on demographics, clinical presentation, investigation results, treatment and outcome were extracted, deidentified and analysed. Results: One hundred ten presentations of Sydenham chorea occurred between 2002 and 2022, 109 (99%) of these were in First Nations children, with 85% residing in very remote locations. Most commonly, chorea presented as a generalised movement disorder affecting all four limbs (49%). Neuropsychiatric symptoms were reported in 33 (30%), and there was evidence of rheumatic heart disease on echocardiogram in 86 (78%) at presentation. All patients received benzathine penicillin, but there was significant variation in management of chorea, ranging from supportive management, to symptomatic management with anticonvulsants, to immunomodulatory medications including corticosteroids. Conclusion: This case series highlights the significant burden of Sydenham chorea among First Nations children living in Northern Australia and demonstrates wide variation in treatment approaches. High‐quality clinical trials are required to determine the best treatment for this disabling condition. [ABSTRACT FROM AUTHOR]

The article discusses the notification of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in hospitalised individuals in the Midwest region of Western Australia from 2012 to 2022. It highlights the higher prevalence of ARF and RHD among First Nations people compared to other Australians and the importance of early diagnosis for better clinical outcomes. The study validated hospitalisations for ARF and RHD, calculated notification rates, and examined factors associated with notification, emphasizing the need for improved clinician awareness and technology to facilitate notification. The research findings aim to address the high non-notification rate of RHD cases and improve monitoring and case management for affected individuals. [Extracted from the article]

Group A Streptococcus (GAS) is a human pathogenic bacterium that can trigger a wide range of diseases, including the autoimmune diseases acute rheumatic fever and rheumatic heart disease, causing major morbidity and mortality in many low‐ and middle‐income countries. Primary intervention programs have had limited success thus far, and a licensed vaccine has yet to be developed. The pilus of GAS is known to be involved in host cell adhesion, biofilm formation and immune evasion. We have a mucosal vaccine in development that expresses the pilus of GAS on the surface of the nonpathogenic bacterium Lactococcus lactis. To expand strain coverage, we combined seven L. lactis constructs, each expressing a different GAS pilus variant, and investigated the systemic and mucosal immune responses following immunization. Mice immunized with this combination showed specific immunoglobin G and immunoglobin A responses to the GAS pilus proteins of vaccine strains, at levels comparable to mice immunized with a single construct. Cross‐reactivity to pilus proteins of nonvaccine strains was also evident. Furthermore, protective efficacy against a homologous strain of GAS in a murine nasopharyngeal colonization model was observed. Overall, this study provides further evidence for using pilus‐expressing lactic acid bacteria as a vaccine to prevent upper respiratory tract GAS infections. [ABSTRACT FROM AUTHOR]

Background: This guideline is an update to the 2014 edition of the European guideline for the management of balanoposthitis. Balanoposthitis describes inflammation of the glans penis and prepuce and is caused by a range of disparate conditions including infection, dermatoses and premalignancy. Objective: The main objectives of this guideline are to aid recognition of the symptoms and signs and complications of penile skin conditions and to offer recommendations on the diagnostic tests and treatment for a selected group of these conditions. Methods: The previous guideline was updated following a literature review and priority was given to randomized controlled trial and systematic review evidence. Results: The updated guideline includes amended management for infective balanitis to provide clear guidance for Group A streptococcal infections, management of on going Lichen sclerosus (to include circumcision and supportive management to reduce the recurrence of genital herpes and warts), additional regimens for Zoonoid change, use of calcineurin inhibitors in management and risk of premalignancy and change of nomenclaturefrom Premalignant conditions to Penile Intraepithelial neoplasia (PeIN). Conclusion: Balanoposthitis has a widerange of causes high quality evidence specific to the management of penile disease is not available for all the conditions described. [ABSTRACT FROM AUTHOR]

Introduction: Sydenham's chorea (SC), prevalent in developing countries and occasionally affecting developed ones, poses a clinical challenge due to the lack of systematic guidelines for diagnosis and treatment. Resulting from Group A Beta‐Hemolytic Streptococcus infection, SC presents various symptoms. This review aims to collect and evaluate available data on SC management to propose a cohesive treatment plan. Methods: We searched PubMed, the Cochrane Library, Google Scholar, and ClinicalTrials.gov for literature on SC management from inception until 24th July 2022. Studies were screened by titles and abstracts. Cochrane Collaboration's Risk of Bias tool (RoB‐1) assessed Randomized Controlled Trials, while the Risk of Bias In Non‐randomized Studies of Interventions (ROBINS‐I) tool evaluated nonrandomized studies. Results: The review includes 11 articles assessing 579 patients. Excluding one study with 229 patients, of the remaining 550 patients, 338 (61.5%) were females. Treatments used were dopamine antagonists in 118 patients, antiepileptics in 198, corticosteroids in 134, IVIG in 7, and PE in 8 patients. Dopamine antagonists, particularly haloperidol, were the primary treatment choice, while valproic acid (VPA) was favored among antiepileptics. Prednisolone, a corticosteroid, showed promising results with weight gain as the only side‐effect. Our review emphasizes the importance of immunomodulators in SC, contrasting previous literature. Conclusion: Despite limitations, dopamine antagonists can serve as first‐line agents in SC management, followed by antiepileptics. The role of immunomodulators warrants further investigation for conclusive recommendations. [ABSTRACT FROM AUTHOR]

Objective: Therapeutic strategies for patients with febrile infection‐related epilepsy syndrome (FIRES) are limited, ad hoc, and frequently ineffective. Based on evidence that inflammation drives pathogenesis in FIRES, we used ex vivo stimulation of peripheral blood mononuclear cells (PBMCs) to characterize the monocytic response profile before and after therapy in a child successfully treated with dexamethasone delivered intrathecally six times between hospital Day 23 and 40 at 0.25 mg/kg/dose. Methods: PBMCs were isolated from serial blood draws acquired during refractory status epilepticus (RSE) and following resolution associated with intrathecal dexamethasone therapy in a previously healthy 9‐year‐old male that presented with seizures following Streptococcal pharyngitis. Cells were stimulated with bacterial or viral ligands and cytokine release was measured and compared to responses in age‐matched healthy control PBMCs. Levels of inflammatory factors in the blood and CSF were also measured and compared to pediatric healthy control ranges. Results: During RSE, serum levels of IL6, CXCL8, HMGB1, S100A8/A9, and CRP were significantly elevated. IL6 was elevated in CSF. Ex vivo stimulation of PBMCs collected during RSE revealed hyperinflammatory release of IL6 and CXCL8 in response to bacterial stimulation. Following intrathecal dexamethasone, RSE resolved, inflammatory levels normalized in serum and CSF, and the PBMC hyperinflammatory response renormalized. Significance: FIRES may be associated with a hyperinflammatory monocytic response to normally banal bacterial pathogens. This hyperinflammatory response may induce a profound neutrophil burden and the consequent release of factors that further exacerbate inflammation and drive neuroinflammation. Intrathecal dexamethasone may resolve RSE by resetting this inflammatory feedback loop. [ABSTRACT FROM AUTHOR]

This article discusses a case of a 54-year-old woman who presented to the hospital with symptoms of acute fevers, abdominal pain, and diarrhea. Initial investigations revealed severe pancolitis, and blood cultures identified Streptococcus pyogenes as the causative agent. The patient was treated with antibiotics and eventually recovered. The article highlights the rare manifestation of group A streptococcal (GAS) colitis and emphasizes the importance of considering uncommon presentations of streptococcal infections in the differential diagnosis for colitis. It also mentions the seasonal surge of invasive GAS disease and the need for household contacts to seek medical attention if they develop symptoms. [Extracted from the article]

Aim: To describe the epidemiology and clinical profile of children and adolescents with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in Victoria, Australia. Methods: A retrospective audit was undertaken of children and adolescents with ARF and RHD attending the Royal Children's and Monash Children's Hospitals in Victoria, Australia between 2010 and 2019. Potential cases were identified by searching multiple sources for relevant ICD‐10‐AM codes and keywords, then reviewed manually. For confirmed cases, we collected data on patient demographics, clinical features, comorbidities and management. Results: Of 179 participants included, there were 108 Victorian residents and 71 non‐Victorian residents. 126 had at least one episode of ARF during the study period and 128 were diagnosed with RHD. In the Victorian resident group, the overall incidence of ARF was 0.8 per 100 000 5–14 year olds. This incidence was higher in Victorian Aboriginal and/or Torres Strait Islander (3.8 per 100 000) and Pacific Islander (32.1 per 100 000) sub‐populations. Of 83 Victorian residents who had an ARF episode, 11 (13%) had a recurrence. Most Victorian residents with RHD had mixed aortic and mitral valve pathology (69.4%) and moderate to severe disease (61.9%). Most non‐Victorian residents were Aboriginal and/or Torres Strait Islander people (80.3%) and were commonly transferred for tertiary or surgical management of RHD (83.1%). Conclusions: ARF and RHD continue to affect the health of significant numbers of children and adolescents living in Victoria, including severe and recurrent disease. Specialised services and a register‐based control program may help to prevent complications and premature death. [ABSTRACT FROM AUTHOR]

Introduction: Group A streptococcus (Streptococcus pyogenes) is one of the most lethal bacterial pathogens of humans, with increased risk of progression to septic shock and multiorgan failure in the pregnant population. The objective of this study is to systematically review the outcomes and management strategies for pregnancy and puerperal group A streptococcus infections in an effort to provide further guidance for prevention and treatment of a rare but lethal infection worldwide. Material and methods: A comprehensive search using puerperium and streptococcus pyogenes terms was completed across several registered databases. A total of 902 articles investigating pregnancy and puerperal group A streptococcus infection were identified, with 40 studies fulfilling inclusion criteria of original research articles in humans published from 1990 onwards reporting four or more unique cases of group A streptococcus in pregnancy or postpartum. This study was registered in PROSPERO: CRD42020198983. Results: A total of 1160 patients with pregnancy and puerperal group A streptococcus infection were identified. Most infections occurred postpartum (91.9%), with 4.7% reported antepartum and 0.6% intrapartum. Bacteremia was present in 49.0% of patients and endometritis in 45.9%. Puerperal sepsis was described in 28.2% of cases and progressed to streptococcal toxic shock syndrome in one‐third of such cases. Overall, the case fatality ratio was 2.0%, with one‐third of the deaths from antenatal cases including 3/22 (13.6%) cases of septic abortion and 10/46 (21.7%) antenatal cases of group A streptococcus infection. Conclusions: Group A streptococcus infection remains an important contributor to pregnancy and puerperal morbidity and mortality. Early recognition, diagnosis and aggressive management are important for favorable outcomes given the serious risk of sepsis and streptococcal toxic shock syndrome. [ABSTRACT FROM AUTHOR]

Heilaohu, the roots of Kadsura coccinea, has been used in Tujia ethnomedicine to treat rheumatic arthritis (RA). Heilaohuacid G (1), a new 3,4-seco-lanostane type triterpenoid isolated from the ethanol extract of Heilaohu, whose structure was determined using HR-ESI-MS data, NMR spectroscopic analyses, and ECD calculations. In this study, our purpose is to elucidate the mechanisms of Heilaohuacid G in the treatment of RA by inhibited proliferation of rheumatoid arthritis-fibroblastoid synovial (RA-FLS) cells and inhibited the inflammatory reactions in LPS-induced RA-FLS and RAW 264.7 cell lines via inhibiting NF-κB pathway. The biological activity screening experiments indicated that Heilaohuacid G significantly inhibited proliferation of RA-FLS cells with IC50 value of 8.16 ± 0.47 μM. CCK-8 assay, ELISA, flow cytometry assay, and Western blot were used to measure the changes of cell viability, apoptosis, and the release of inflammatory cytokines. Heilaohuacid G was found not only induced RA-FLS cell apoptosis, but also inhibited the inflammatory reactions in LPS-induced RA-FLS and RAW 264.7 cell lines via inhibiting NF-κB pathway. Furthermore, Heilaohuacid G (p.o.) at doses of 3.0, 6.0, and 12.0 mg/kg and the ethanol extracts of Heilaohu (p.o.) at doses of 200, 400, and 800 mg/kg both were confirmed antiinflammatory effects on xylene-induced ear mice edema model.

Group A streptococcal (GAS) infection is associated with a spectrum of autoimmune diseases including acute rheumatic fever/rheumatic heart disease (ARF/RHD) and neurobehavioral abnormalities. Antibodies against GAS M proteins cross‐react with host tissue proteins in the heart and brain leading to the symptomatology observed in ARF/RHD. As throat carriage of Streptococcus dysgalactiae subspecies equisimilis (SDSE) has been reported to be relatively high in some ARF/RHD endemic regions compared with GAS, and both SDSE and GAS express coiled‐coil surface protein called M protein, we hypothesized that streptococci other than GAS can also associated with ARF/RHD and neurobehavioral abnormalities. Neurobehavioral assessments and electrocardiography were performed on Lewis rats before and after exposure to recombinant GAS and SDSE M proteins. Histological assessments were performed to confirm inflammatory changes in cardiac and neuronal tissues. ELISA and Western blot analysis were performed to determine the cross‐reactivity of antibodies with host connective, cardiac and neuronal tissue proteins. Lewis rats injected with M proteins either from GAS or SDSE developed significant cardiac functional and neurobehavioral abnormalities in comparison to control rats injected with phosphate‐buffered saline. Antibodies against GAS and SDSE M proteins cross‐reacted with cardiac, connective and neuronal proteins. Serum from rats injected with streptococcal antigens showed higher immunoglobulin G binding to the striatum and cortex of the brain. Cardiac and neurobehavioral abnormalities observed in our experimental model were comparable to the cardinal symptoms observed in patients with ARF/RHD. Here for the first time, we demonstrate in an experimental model that M proteins from different streptococcal species could initiate and drive the autoimmune‐mediated cardiac tissue damage and neurobehavioral abnormalities.

Guttate psoriasis (GP) is a type of psoriasis characterized by a sudden outbreak of red, scaly, drop-like bumps on the skin, often occurring after an infection. While most cases of GP resolve within a few months, some patients develop chronic plaque psoriasis. Traditional treatments for GP include topical corticosteroids and phototherapy. However, a recent case study suggests that early treatment with guselkumab, a medication that blocks interleukin (IL)-23, may lead to long-term disease control and remission in GP patients. Further research is needed to fully understand the effectiveness of IL-23 inhibitors in treating GP. [Extracted from the article]

The Medical Journal of Australia published an article discussing Australia's strategy to eliminate rheumatic heart disease (RHD) by 2031. The National Aboriginal Community Controlled Health Organisation (NACCHO) has partnered with the Australian Government to combat acute rheumatic fever (ARF) and RHD, with a focus on Aboriginal and Torres Strait Islander communities. This partnership is the first of its kind globally, shifting power and decision-making to community control. NACCHO is responsible for distributing over $30 million in service enhancement grants to address local priorities and strengthen resources. The article emphasizes the importance of addressing social and cultural determinants of health to prevent ARF and RHD. [Extracted from the article]

The ocular manifestations of RA such as episcleritis and scleritis are important to consider in this patient, as the bilateral conjunctival injection observed in this patient may reflect an underlying systemic inflammatory process. Although the patient was at a low risk for developing ARF, as it is significantly less common in the US than underdeveloped countries, the presence of clinical carditis, polyarthralgia, fever of >=38.5°C, and significantly elevated markers of inflammation are sufficient to fulfill the 2015 Jones criteria for rheumatic fever and support the diagnosis of ARF in this patient. The angiographic findings suggestive of coronary vasculitis, and biopsy-proven vasculitis of small to medium-sized testicular arteries led to the specific diagnosis of PAN, which enabled the patient to receive the appropriate treatment for his underlying disease.

Pulmonary‐renal syndrome (PRS) is defined as a combination of diffuse alveolar haemorrhage and glomerulonephritis. An 18‐year‐old woman visited our hospital with a 2‐day history of fever, dyspnoea, and leg edema. Laboratory investigations revealed an elevated inflammatory reaction, increased serum creatinine levels, and normocytic anaemia. Additionally, the anti‐streptolysin‐O titre was positive, and complement component‐3 levels were decreased. Urinalysis revealed proteinuria and hematuria. Bronchoalveolar lavage aliquots were progressively more hemorrhagic. These findings supported a diagnosis of PRS secondary to streptococcal infection. The patient was treated with high‐dose methylprednisolone and antibiotics. After 4 days of treatment, her respiratory symptoms and serum creatinine levels improved. Steroid tapering was performed over 15 days. The findings in this case indicate that streptococcal infection is a potential cause of PRS, and that short‐term steroid therapy is an effective treatment. [ABSTRACT FROM AUTHOR]

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal (PANDAS) infections and pediatric acute‐onset neuropsychiatric syndrome (PANS) are typically diagnosed in childhood. Therapeutic plasma exchange (TPE) has been recommended to remove relevant antibodies and treat symptomatic presentations in children and adolescents, but there are no studies that evaluate the use of TPE in patients who are diagnosed later in life. It is therefore unclear if using an accepted treatment for pediatric PANS/PANDAS patients would be beneficial in adults with prolonged PANDAS/PANS symptomatic histories. This study investigated 16 late adolescent and adult PANDAS/PANS patients' responses to TPE. Improvement was noted in over half of the patients with available follow‐up information.

Aim: To evaluate the incidence and clinical features of acute rheumatic fever (ARF) in Turkey, following the revised Jones criteria in 2015. Methods: This multicentre study was designed by the Acquired Heart Diseases Working Group of the Turkish Pediatric Cardiology and Pediatric Cardiac Surgery Association in 2016. The data during the first attack of 1103 ARF patients were collected from the paediatric cardiologists between 1 January 2016 and 31 December 2016. Results: Turkey National Institute of Statistics records of 2016 were used for the determination of ARF incidence with regard to various cities and regions separately. The estimated incidence rate of ARF was 8.84/100 000 in Turkey. The ARF incidence varied considerably among different regions. The highest incidence was found in the Eastern Anatolia Region as 14.4/100 000, and the lowest incidence was found in the Black Sea Region as 3.3/100 000 (P < 0.05). Clinical carditis was the most common finding. The incidence of clinical carditis, subclinical carditis, polyarthritis, aseptic monoarthritis, polyarthralgia and Sydenham's Chorea was 53.5%, 29.1%, 52.8%, 10.3%, 18.6% and 7.9%, respectively. The incidences of clinical carditis, subclinical carditis, polyarthritis and polyarthralgia were found to be significantly different among different regions (P < 0.05). Conclusion: The findings of this nationwide screening of ARF suggest that Turkey should be included in the moderate‐risk group. [ABSTRACT FROM AUTHOR]

The increasingly widespread use of meta‐analysis has led to growing interest in meta‐analytic methods for rare events and sparse data. Conventional approaches tend to perform very poorly in such settings. Recent work in this area has provided options for sparse data, but these are still often hampered when heterogeneity across the available studies differs based on treatment group. We propose a permutation‐based approach based on conditional logistic regression that accommodates this common contingency, providing more reliable statistical tests when such patterns of heterogeneity are observed. We find that commonly used methods can yield highly inflated Type I error rates, low confidence interval coverage, and bias when events are rare and non‐negligible heterogeneity is present. Our method often produces much lower Type I error rates and higher confidence interval coverage than traditional methods in these circumstances. We illustrate the utility of our method by comparing it to several other methods via a simulation study and analyzing an example data set, which assess the use of antibiotics to prevent acute rheumatic fever.

Acute rheumatic fever (ARF) and its sequela rheumatic heart disease (RHD) remain significant causes of morbidity and mortality. In New Zealand, ARF almost exclusively affects Indigenous Māori and Pacific children. This narrative review aims to present secondary interventions to improve early and accurate diagnosis of ARF and RHD, in order to minimise disease progression in New Zealand. Medline, EMBASE and Scopus databases were searched as well as other electronic publications. Included were 56 publications from 1980 onwards. Diagnosing ARF and RHD as early as possible is central to reducing disease progression. Recent identification of specific ARF biomarkers offer the opportunity to aid initial diagnosis and portable echocardiography has the potential to detect undiagnosed RHD in high‐risk areas. However, further research into the benefits and risks to children with subclinical RHD is necessary, as well as an economic evaluation. [ABSTRACT FROM AUTHOR]

Aim: To describe the clinical features, treatment and outcomes of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in children admitted to the national referral hospital in Dili, Timor‐Leste. Methods: This prospective study documented cases of ARF and RHD in children aged 14 years and under who were admitted between June 2017 and May 2019. ARF was diagnosed using an adapted version of the 2015 Jones criteria and presumed (rather than proven) exposure to group A Streptococcus. Clinical and echocardiographic findings, comorbidities and discharge outcomes are reported. Results: A total of 63 patients were admitted with ARF or RHD; 54 were diagnosed with RHD for the first time. Median age was 11 years (range 3–14); 48% were female. Of those with echocardiograms, 56/58 had RHD, 55/56 (98%) had mitral regurgitation (37/55 (67%) severe), 11/56 (20%) had mitral stenosis and 43/56 (77%) had aortic regurgitation. Left ventricular dysfunction (55%), pulmonary hypertension (64%) and cardiac failure (78%) were common. Four (6%) patients died in hospital, and 30/59 (51%) of surviving patients were lost to follow up. Conclusions: Community echocardiography screening has reported a high prevalence of undetected mild to moderate cases of RHD in Timor‐Leste, whereas this hospital study documents mostly severe disease among hospitalised patients with a high case fatality rate and loss to follow up. RHD is a significant health problem in Timor‐Leste and improved recognition and diagnosis, as well as effective delivery of treatment and follow‐up are imperative. [ABSTRACT FROM AUTHOR]

Objective: To quantify the burden of invasive group A Streptococcus (GAS) disease in Western Australia during 2000–2018. Design, setting: Population‐based data linkage study: Hospital Morbidity Data Collection (HMDC; all WA public and private hospital records), PathWest pathology data (government‐owned pathology services provider), and death registrations. Participants: People with invasive GAS disease, defined by an isolate from a normally sterile site (PathWest) or a hospital‐based principal ICD‐10‐AM diagnosis code (HMDC). Main outcome measures: Incidence of invasive GAS disease; median length of hospital stay; all‐cause mortality. Results: We identified 2237 cases of GAS disease during 2000‒2018; 1283 were in male patients (57%). 1950 cases had been confirmed by GAS isolates from normally sterile tissues (87%; including 1089 from blood [56% of cases] and 750 from tissue [38%]). The age‐standardised incidence increased from 2.0 (95% CI, 1.4–2.7) cases per 100 000 population in 2000 to 9.1 (95% CI, 7.9–10.2) cases per 100 000 in 2017 (by year, adjusted for age group and sex: incidence rate ratio [IRR], 1.09; 95% CI, 1.08–1.10). Incidence was consistently higher among Indigenous than non‐Indigenous Australians (year‐adjusted IRR, 13.1; 95% CI, 11.3–15.1). All‐cause 30‐day mortality was 5% (116 deaths), and 90‐day mortality 7% (156 deaths); 30‐day mortality, adjusted for age group and sex, was not statistically significantly different for cases involving Indigenous or non‐Indigenous patients (adjusted odds ratio, 0.8; 95% CI, 0.6–1.1). Conclusions: The incidence of invasive GAS disease in WA increased between 2000 and 2018, particularly among Indigenous Australians. Mandatory notification of invasive GAS disease would therefore be appropriate. The social determinants of differences in incidence should be addressed, and other relevant host, pathogen, and health system factors investigated. [ABSTRACT FROM AUTHOR]

Rheumatic heart disease (RHD) is a large, preventable, global public health burden. In New Zealand (NZ), acute rheumatic fever (ARF) and RHD rates are highest for Māori and Pacific children. This structured review explores the evidence for primary prevention interventions to diagnose and effectively treat group A Streptococcus (GAS) pharyngitis and skin infections to reduce rates of ARF and RHD. Medline, EMBASE and Scopus databases were searched as well as other electronic publications. Included were 50 publications from 1980 onwards. This review has identified that there is little available evidence for effective primary prevention strategies to reduce ARF rates in NZ. However, two primary intervention strategies that should be considered by communities at high-risk of ARF are: the use of school-based clinics to identify and treat GAS pharyngitis and GAS skin infections; and intramuscular benzathine penicillin G with lignocaine analgesia in children who present with a GAS positive throat.

Valvular involvement such as aortic and/or mitral regurgitation may be seen in patients with TA and therefore these patients may be misdiagnosed as rheumatic carditis. Acute rheumatic fever (ARF) and Takayasu arteritis (TA) have clinical features in common, including carditis, fever, arthritis/arthralgia and raised acute phase reactants; this may lead to misdiagnosis.

Aim: While mostly eradicated in developed nations, rheumatic heart disease (RHD) is still the leading cause of preventable cardiovascular disease in children. RHD and its antecedent acute rheumatic fever remain endemic in many low to middle income countries, as well as in vulnerable communities in wealthy ones. Evidence-based interventions are particularly important in resource-poor settings. We sought to determine if efforts directed at patient and family education impact degree of participation in community-based prevention measures, and with short-term disease progression.Methods: We performed an observational, cross-sectional study of children with RHD aged 5-19 years, along with their parents, in American Samoa. A survey was administered in November 2016 to assess patient and parent knowledge of RHD. Scores were compared to percent timeliness of penicillin prophylaxis via chart review.Results: We collected a total of 70 surveys of child-parent dyads with a patient mean age of 14.28 years ±2.71. An increased knowledge score was predictive of increased penicillin compliance for both children (12.70% increase in compliance per 1-unit increase in score (P = 0.0004)) and parents (10.10% increase in compliance per 1-unit increase in score (P = 0.0012)).Conclusions: A clear relationship exists between patient and parent knowledge of RHD and timeliness of penicillin prophylaxis doses. This study was the first to link patient understanding of RHD to engagement with preventative measures. [ABSTRACT FROM AUTHOR]

Introduction: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) cause significant morbidity and premature mortality among Australian Aboriginal and Torres Strait Islander peoples. RHDAustralia has produced a fully updated clinical guideline in response to new knowledge gained since the 2012 edition. The guideline aligns with major international ARF and RHD practice guidelines from the American Heart Association and World Heart Federation to ensure best practice. The GRADE system was used to assess the quality and strength of evidence where appropriate. Main recommendations: The 2020 Australian guideline details best practice care for people with or at risk of ARF and RHD. It provides up‐to‐date guidance on primordial, primary and secondary prevention, diagnosis and management, preconception and perinatal management of women with RHD, culturally safe practice, provision of a trained and supported Aboriginal and Torres Strait Islander workforce, disease burden, RHD screening, control programs and new technologies. Changes in management as a result of the guideline: Key changes include updating of ARF and RHD diagnostic criteria; change in secondary prophylaxis duration; improved pain management for intramuscular injections; and changes to antibiotic regimens for primary prevention. Other changes include an emphasis on provision of culturally appropriate care; updated burden of disease data using linked register and hospitalisations data; primordial prevention strategies to reduce streptococcal infection addressing household overcrowding and personal hygiene; recommendations for population‐based echocardiographic screening for RHD in select populations; expanded management guidance for women with RHD or ARF to cover contraception, antenatal, delivery and postnatal care, and to stratify pregnancy risks according to RHD severity; and a priority classification system for presence and severity of RHD to align with appropriate timing of follow‐up.

Aim: Secondary prophylaxis with 3–4 weekly benzathine penicillin G injections is necessary to prevent disease morbidity and cardiac mortality in patients with acute rheumatic fever (ARF) and rheumatic heart disease (RHD). This study aimed to determine secondary prophylaxis adherence rates in the Far North Queensland paediatric population and to identify factors contributing to suboptimal adherence. Methods: A retrospective analysis of data recorded in the online RHD register for Queensland, Australia, was performed for a 10‐year study period. The proportion of benzathine penicillin G injections delivered within intervals of ≤28 days and ≤35 days was measured. A multi‐level mixed model logistic regression assessed the influence of age, gender, ethnicity, suburb, Accessibility and Remoteness Index of Australia class, number of people per dwelling, Index of Relative Socio‐economic Advantage and Disadvantage, Index of Education and Occupation, year of inclusion on an ARF/RHD register and individual effect. Results: The study included 277 children and analysis of 7374 injections. No children received ≥80% of recommended injections within a 28‐day interval. Four percent received ≥50% of injections within ≤28 days and 46% received ≥50% of injections at an extended interval of ≤35 days. Increasing age was associated with reduced delivery of injections within 35 days. Increasing year of inclusion was associated with improved delivery within 28 days. The random effect of individual patients was significantly associated with adherence. Conclusions: Improved timely delivery of secondary prophylaxis for ARF and RHD is needed as current adherence is very low. Interventions should focus on factors specific to each individual child or family unit. [ABSTRACT FROM AUTHOR]

Rheumatic heart disease (RHD) is a pan-carditis resulting from an altered immune response to Group A -hemolytic Streptococcal pharyngitis.1 It is the leading cause of heart failure in children and young adults worldwide. Intraoperative findings included thickened MV leaflets with vegetation-like lesions over all leaflets (Figure 1a). [Extracted from the article]

■The RHD Endgame Strategy: the blueprint to eliminate rheumatic heart disease in Australia by 2031 (the Endgame Strategy) is the blueprint to eliminate rheumatic heart disease (RHD) in Australia by 2031. Aboriginal and Torres Strait Islander people live with one of the highest per capita burdens of RHD in the world. ■The Endgame Strategy synthesises information compiled across the 5-year lifespan of the End Rheumatic Heart Disease Centre of Research Excellence (END RHD CRE). Data and results from priority research projects across several disciplines of research complemented literature reviews, systematic reviews and narrative reviews. Further, the experiences of those working in acute rheumatic fever (ARF) and RHD control and those living with RHD to provide the technical evidence for eliminating RHD in Australia were included. ■The lived experience of RHD is a critical factor in health outcomes. All future strategies to address ARF and RHD must prioritise Aboriginal and Torres Strait Islander people's knowledge, perspectives and experiences and develop co-designed approaches to RHD elimination. The environmental, economic, social and political context of RHD in Australia is inexorably linked to ending the disease. ■Statistical modelling undertaken in 2019 looked at the economic and health impacts of implementing an indicative strategy to eliminate RHD by 2031. Beginning in 2019, the strategy would include: reducing household crowding, improving hygiene infrastructure, strengthening primary health care and improving secondary prophylaxis. It was estimated that the strategy would prevent 663 deaths and save the health care system $188 million. ■The Endgame Strategy provides the evidence for a new approach to RHD elimination. It proposes an implementation framework of five priority action areas. These focus on strategies to prevent new cases of ARF and RHD early in the causal pathway from Streptococcus pyogenes exposure to ARF, and strategies that address the critical systems and structural changes needed to support a comprehensive RHD elimination strategy.

Children's perspectives rarely appear at strategic levels in public health. Policy‐makers can hold adult‐centric assumptions about children, and may be uncertain about how to interpret and apply children's perspectives in policy. Yet how children experience and perceive health interventions can shape the success of services. What, then, might child‐centred approaches to health policy consider? Through ethnographic work in New Zealand, I document how children engage with a school rheumatic fever prevention service, and provide a framework of three lenses through which policy‐makers can more meaningfully consider children's perspectives on health: (a) The embodied‐child; (b) the social‐child, and (c) the public‐child.

Aim: Acute rheumatic fever (ARF) most commonly presents in children aged 5-14 years old. Lifelong rheumatic heart disease (RHD) can result. This study investigated time trends in ARF and RHD using inpatient data from the Royal Children's Hospital, Melbourne (RCH).Methods: A retrospective cohort study covering the period 1937-2013 was conducted using records from RCH, a quaternary paediatric hospital in Melbourne, Victoria, Australia. Patient data were identified using RCH classification of diseases coding for ARF or RHD for years <1952. For the period 1952-1987, this system was used in addition to identifying International Classification of Disease (ICD) discharge codes that corresponded to ARF or RHD. From 1988-2013, only ICD codes were used to identify patient data. Descriptive epidemiological analyses were performed, including incidence rate calculations using historical census population denominator data. Analyses focussed on children in the peak age group.Results: Among children aged five to 14 years, a total of 4337 RCH admissions with ARF/RHD occurred for 3015 patients. A sharp decline in first ARF/RHD hospitalisations at RCH occurred from 1959, following a peak mean annual incidence rate during 1944-1947 of 40.1/100 000 children (95% confidence interval (CI): 36.6-43.9; P < 0.05). Over 1996-2013, the mean annual incidence rate was 1.6/100 000 (95% CI: 1.3-1.8) and reached 2.3/100 000 (95% CI: 1.3-3.7) in 2005.Conclusion: The burden of ARF and RHD treated at RCH declined following the 1940s, mirroring changes seen in North America and Europe. Despite this, inpatient treatment for these conditions continued to be provided right up until the end of the study period. [ABSTRACT FROM AUTHOR]

Objectives: Using echocardiographic screening, to estimate the prevalence of rheumatic heart disease (RHD) in a remote Northern Territory town.Design: Prospective, cross-sectional echocardiographic screening study; results compared with data from the NT rheumatic heart disease register.Setting, Participants: People aged 5-20 years living in Maningrida, West Arnhem Land (population, 2610, including 2366 Indigenous Australians), March 2018 and November 2018.Intervention: Echocardiographic screening for RHD by an expert cardiologist or cardiac sonographer.Main Outcome Measures: Definite or borderline RHD, based on World Heart Federation criteria; history of acute rheumatic fever (ARF), based on Australian guidelines for diagnosing ARF.Results: The screening participation rate was 72%. The median age of the 613 participants was 11 years (interquartile range, 8-14 years); 298 (49%) were girls or women, and 592 (97%) were Aboriginal Australians. Definite RHD was detected in 32 screened participants (5.2%), including 20 not previously diagnosed with RHD; in five new cases, RHD was classified as severe, and three of the participants involved required cardiac surgery. Borderline RHD was diagnosed in 17 participants (2.8%). According to NT RHD register data at the end of the study period, 88 of 849 people in Maningrida and the surrounding homelands aged 5-20 years (10%) were receiving secondary prophylaxis following diagnoses of definite RHD or definite or probable ARF.Conclusion: Passive case finding for ARF and RHD is inadequate in some remote Australian communities with a very high burden of RHD, placing children and young people with undetected RHD at great risk of poor health outcomes. Active case finding by regular echocardiographic screening is required in such areas. [ABSTRACT FROM AUTHOR]

Aim: Recent studies have linked scabies with acute rheumatic fever (ARF). We explored the relationship, by neighbourhood, between permethrin dispensing as an indicator of scabies prevalence and ARF cases over the same period.Methods: Incident cases of ARF notified to public health between September 2015 and June 2018 and the annual incidence of prescribing by neighbourhood over the same period were analysed. Evidence of an association between permethrin and ARF was obtained by carrying out Poisson regression of the rate of ARF in terms of permethrin rate at the census area unit level, with adjustment for ethnicity and socio-economic deprivation.Results: A total of 413 neighbourhoods were included. The incidence of ARF varied between 0 and 102 per 100 000 people per year (mean 4.3). In contrast, the annual incidence of dispensing of permethrin varied between 0 and 3201 per 100 000 people per year (mean 771). A strong association was observed between the two variables. In an adjusted quasi-Poisson model, permethrin-dispensing rates were strongly associated with ARF incidence, with a change from the 16th to the 84th centile associated with a 16.5-fold increase in incidence (95% confidence interval: 3.82-71.6).Conclusions: Permethrin prescribing as an indicator of scabies is strongly associated with the incidence of ARF. Considered together with other studies, this evidence suggests that improving scabies control may reduce the burden of ARF in New Zealand. [ABSTRACT FROM AUTHOR]

Impetigo, scabies, cellulitis and abscesses are common in Australian Aboriginal children. These conditions adversely affect wellbeing and are associated with serious long term sequelae, including invasive infection and post-infectious complications, such as acute post-streptococcal glomerulonephritis and acute rheumatic fever, which occurs at the highest documented rates in the world in remote Aboriginal communities. Observational research in remote communities in northern Australia has demonstrated a high concurrent burden of scabies and impetigo and their post-infectious complications. Few data are available for other Australian states, especially for urban Aboriginal children; however, nationwide hospital data indicate that the disparity between Aboriginal and non-Aboriginal children in skin infection prevalence also exists in urban settings. The Australian National Healthy Skin Guideline summarises evidence-based treatment of impetigo, scabies and fungal infections in high burden settings such as remote Aboriginal communities. It recommends systemic antibiotics for children with impetigo, and either topical permethrin or oral ivermectin (second line) for the individual and their contacts as equally efficacious treatments for scabies. β-Lactams are the treatment of choice and trimethoprim-sulfamethoxazole and clindamycin are effective alternatives for treatment of paediatric cellulitis. Abscesses require incision and drainage and a 5-day course of trimethoprim-sulfamethoxazole or clindamycin. Addressing normalisation of skin infections and the social determinants of skin health are key challenges for the clinician. Research is underway on community-wide skin health programs and the role for mass drug administration which will guide future management of these common, treatable diseases. [ABSTRACT FROM AUTHOR]

Acute rheumatic fever (ARF) and chronic rheumatic heart disease (RHD) are autoimmune sequelae of a Group A streptococcal infection with significant global mortality and poorly understood pathogenesis. Immunoglobulin and complement deposition were observed in ARF/RHD valve tissue over 50 years ago, yet contemporary investigations have been lacking. This study applied systems immunology to investigate the relationships between the complement system and immunoglobulin in ARF. Patients were stratified by C‐reactive protein (CRP) concentration into high (≥10 μg mL−1) and low (<10 μg mL−1) groups to distinguish those with clinically significant inflammatory processes from those with abating inflammation. The circulating concentrations of 17 complement factors and six immunoglobulin isotypes and subclasses were measured in ARF patients and highly matched healthy controls using multiplex bead‐based immunoassays. An integrative statistical approach combining feature selection and principal component analysis revealed a linked IgG3–C4 response in ARF patients with high CRP that was absent in controls. Strikingly, both IgG3 and C4 were elevated above clinical reference ranges, suggesting these features are a marker of ARF‐associated inflammation. Humoral immunity in response to M protein, an antigen implicated in ARF pathogenesis, was completely polarized to IgG3 in the patient group. Furthermore, the anti‐M‐protein IgG3 response was correlated with circulating IgG3 concentration, highlighting a potential role for this potent immunoglobulin subclass in disease. In conclusion, a linked IgG3–C4 response appears important in the initial, inflammatory stage of ARF and may have immediate utility as a clinical biomarker given the lack of specific diagnostic tests currently available.

Rheumatic heart disease, as a result of a single or recurrent episode of acute rheumatic fever (ARF), remains a significant cause of morbidity and mortality in northern and remote Australia; ARF has a peak incidence among 5-14-year-old Aboriginal and Torres Strait Islander children. Long-term regular benzathine penicillin G injections are the only currently successful secondary prevention strategy; however, rates of adherence remain critically low. In contrast, rates of adherence to immunisations on the National Immunisation Program (NIP) Schedule are high, even among this target population. This article compares strategies used to implement and improve ARF secondary prophylaxis with those used in the NIP. Some successful NIP strategies, such as Service Incentive Payment for health providers, home-visiting delivery models and integration into the National Immunisation Register, if applied to ARF secondary prophylaxis have the potential to improve benzathine penicillin G adherence.

Moving from newborns to naïve T cells, Sood I et al i .4 ask the question, "Are all naïve T cells equal?" The articles by Li I et al i .9 and Obeidy I et al i .8 also center on T-cell function, but this time on two factors that enable cytotoxic T-cell (CTL) effector function: dendritic cell (DC) subsets and actin-related protein 2/3 (Arp2/3). Partial loss of actin nucleator actin-related protein 2/3 activity triggers blebbing in primary T lymphocytes. [Extracted from the article]

The article discusses challenging business for Acute Rheumatic Fever (ARF) and Rheumatic Heart Disease(RHD) in Australia. Topics include recommending secondary prevention with intramuscular benzathine benzylpenicillin G (BPG) to prevent recurrences of ARF and progression of RHD; and the pharmaceutical industry making impressive contributions to improve in public health and chronic disease management with vaccination; and the future and hospital pharmacists.

A 12-year-old girl, with atopic dermatitis since childhood, was referred for an acquired and painful transgradient palmoplantar keratoderma (PPK), thought to be inherited. Crusted scabies presentation in children is variable and can present as keratoderma over acral surfaces, onychodystrophy, subungual hyperkeratosis, or erythrodermic dermatitis.[[1], [3]] Pruritus is variable. The treatment remains difficult; crusted scabies is often resistant to topical treatment alone. [Extracted from the article]

Aim: This study sought to determine whether scabies infection is associated with acute rheumatic fever (ARF) or chronic rheumatic heart disease (CRHD).Methods: A cohort study was undertaken using health records of children aged 3-12 years attending an oral health service for the first time. Subjects were then linked to hospital diagnoses of scabies and ARF or CRHD.Results: A total of 213 957 children free of rheumatic heart disease at baseline were available for analysis. During a mean follow-up time of 5.1 years, 440 children were diagnosed with ARF or CRHD in hospital records. Children diagnosed with scabies during follow-up were 23 times more likely to develop ARF or CRHD, compared with children who had no scabies diagnosis. After adjustment for confounders in a Cox model, the association reduced but remained strong (adjusted hazard ratio: 8.98; 95% confidence interval: 6.33-20.2). In an analysis restricted to children hospitalised at least once during follow-up, the adjusted hazard ratio for the same comparison was 3.43 (95% confidence interval: 1.85-6.37).Conclusions: A recent diagnosis of scabies from hospital records is strongly associated with a subsequent diagnosis of ARF. Further investigation of the role that scabies infestation may play in the aetiology of ARF is warranted. [ABSTRACT FROM AUTHOR]
