Streptococcus pyogenes infections in Spanish children before and after the COVID pandemic. Coming back to the previous incidence

Introduction Group A Streptococcus (GAS) causes mild diseases, and unfrequently invasive infections (iGAS). Following the December 2022 alert from the United Kingdom regarding the unusual increase in GAS and iGAS infections, we analyzed the incidence of GAS infections in 2018–2022 in our hospital. Methods We conducted a retrospective study of patients seen in a pediatric emergency department (ED) diagnosed with streptococcal pharyngitis and scarlet fever and patients admitted for iGAS during last 5 years. Results The incidence of GAS infections was 6.43 and 12.38/1000 ED visits in 2018 and 2019, respectively. During the COVID-19 pandemic the figures were 5.33 and 2.14/1000 ED visits in 2020 and 2021, respectively, and increased to 10.2/1000 ED visits in 2022. The differences observed were not statistically significant (p=0.352). Conclusions In our series, as in other countries, GAS infections decreased during the COVID-19 pandemic, and mild and severe cases increased considerably in 2022, but did not reach similar levels to those detected in other countries. Resumen Introducción Streptococcus del grupo A (GAS) causa infecciones leves y ocasionalmente invasivas (iGAS). Tras la alerta publicada en diciembre de 2022 en el Reino Unido respecto al aumento de infecciones por GAS leves e iGAS, analizamos la incidencia de estas infecciones en 2018-2022 en nuestro hospital. Métodos Realizamos un estudio retrospectivo de los niños atendidos en urgencias pediátricas (UP) diagnosticados de faringitis estreptocócica y escarlatina y los ingresados por iGAS durante 5 años. Resultados La incidencia de infecciones por GAS fue de 6,43 y de 12,38/1.000 visitas a UP en 2018 y 2019, respectivamente. Durante la pandemia fue de 5,33 y de 2,14/1.000 visitas en 2020 y 2021, respectivamente, y aumentó a 10,2/1.000 visitas en 2022. Estas diferencias no fueron estadísticamente significativas (p=0,352). Discusión En nuestra serie, al igual que en otros países, las infecciones por GAS disminuyeron durante la pandemia de COVID-19, pero en 2022 aumentaron considerablemente los casos leves y graves, sin alcanzar cifras similares a las detectadas en otros países.

Antibiotic Use in Acute Upper Respiratory Tract Infections

Upper respiratory tract infections are responsible for millions of physician visits in the United States annually. Although viruses cause most acute upper respiratory tract infections, studies show that many infections are unnecessarily treated with antibiotics. Because inappropriate antibiotic use results in adverse events, contributes to antibiotic resistance, and adds unnecessary costs, family physicians must take an evidence-based, judicious approach to the use of antibiotics in patients with upper respiratory tract infections. Antibiotics should not be used for the common cold, influenza, COVID-19, or laryngitis. Evidence supports antibiotic use in most cases of acute otitis media, group A beta-hemolytic streptococcal pharyngitis, and epiglottitis and in a limited percentage of acute rhinosinusitis cases. Several evidence-based strategies have been identified to improve the appropriateness of antibiotic prescribing for acute upper respiratory tract infections.Copyright © 2022 American Academy of Family Physicians.

Standardizing Strep Throat Documentation in a Pediatric Outpatient Setting During COVID-19: A Quality Improvement Pilot Project.

Clinicians' nonadherence to the 2012 Infectious Diseases Society of America's group A streptococcal (GAS) pharyngitis guidelines leads to unnecessary in-person clinic visits, unnecessary use of bacterial testing, and inappropriate antibiotic prescriptions. Quality improvement methodology was used during nurse telephone triage at an outpatient pediatric clinic to standardize nurse documentation to align with the GAS guidelines. This pilot project's standardization resulted in improved communication among clinicians and decreased unnecessary resource and antibiotic use despite encountering barriers related to COVID-19.

Evaluation of patient perspective of point of care testing and medication: Dispensing by community pharmacists for Streptococcus pyogenes and influenza

Background: Recent state-level legislation allows pharmacies to implement protocols for the testing and treatment of influenza and group A streptococcal pharyngitis infections, which may improve access. Objective(s): This study evaluated patient perspectives on testing and treatment of influenza or streptococcal pharyngitis infections in the pharmacy and evaluated patient acceptance, willingness to seek testing, and willingness to pay. Method(s): This study used a cross-sectional paper survey administered at the community pharmacy after receiving a coronavirus disease 2019 vaccine. The survey consisted of multiple choice and rank order. Surveys were anonymous and returned after completion before leaving the pharmacy. Survey data were entered into an Excel database for analysis. Result(s): There were a total of 152 respondents. Most of them were older than the age of 50 years and female. Most (89%) have a primary care provider (PCP) and their preferred location for testing was their PCP or a walk-in, quick care setting. More than half of the respondents stated that they would use the pharmacy as a source for testing and treatment for streptococcal pharyngitis infections and influenza. Half of the respondents pay an office copay visit of less than $15 and 29% pay $25-$50 per visit. The majority of respondents (62%) were willing to pay $25 or more out of pocket for testing. Conclusion(s): Although the pharmacy was not the preferred site for testing, more than half of the respondents stated that they would use the pharmacy for testing and treatment. Most respondents' willingness to pay was more than their copayments for office visits, suggesting some may value the convenience of testing and treatment at the pharmacy.

A paralysis poser: a growing COVID concern

Purpose of Study: Report a rare case of onset of seronegative, juvenile dermatomyositis likely potentiated by Covid-19 infection Methods Used: Case analysis and literature research Summary of Results: A 7 year-old previously healthy male presented with 3 weeks of progressive, bilateral upper and lower extremity weakness, difficulty swallowing, voice changes, periorbital edema, and rash. Recent history was notable for diagnoses of COVID-19 one month prior to presentation and streptococcal pharyngitis 2 months prior to presentation. Notably, there is a family history of systemic lupus erythematosus. On examination, the patient demonstrated bilateral periorbital swelling with purple discoloration of the upper eyelids, a violaceous, pruritic, macular rash on his upper extremities and on his abdomen. Musculoskeletal exam was significant for severe axial (strength 2/5) and proximal (strength 3/5) muscleweakness with notable inability to sit unsupported or maintain head control. His neurologic exam was nonfocal;however, diffuse hyporeflexia in both upper and lower extremities were elicited. Initial screening labs were notable for mild transaminitis;positive ANA (1:80 in speckled pattern), negative ANCA, negative dsDNA/Anti- Sm, elevated aldolase of 10.3, CK 464, and LDH 665;normal thyroid studies and normal inflammatory markers. MRI with and without contrast of the spine indicated diffuse myositis of all muscle groups. Due to concern for autoimmune mediated myositis, Rheumatology was involved early in the patient's course. Empiric treatment was initiated early in the patient's presentation with IVIG, steroids, methotrexate, and plaquenil leading to gradual improvement in symptoms. Subsequent muscle biopsy was consistent with juvenile dermatomyositis (JDM). Conclusion(s): JDM is rare, occurring in 1 to 15 per million children. It classically presents with proximal myopathy and dermatologic findings of Gattron's papules, a heliotrope and malar rash. Its pathophysiology is not yet well defined but is thought to be a humoral mediated autoimmune disease. Muscle biopsies characteristically show perifascicular and perivascular infiltration. Early diagnosis and treatment with steroids, immune modulators, and physical therapy is critical to limit muscle atrophy. Viral infections are known triggers of rheumatologic diseases broadly;however, the more pronounced type 1 interferon response associated with COVID-19, which is known to be a driving pathway of JDM, may be a risk factor for severe, recalcitrant disease. Future research is needed to better identify involved pathophysiology and target future treatment efforts. Additionally, more education and case reports could focus on dermatologic presentations of individuals with pigmented skin. Copyright © 2023 Southern Society for Clinical Investigation.

ANTISYNTHETASE SYNDROME PRESENTING AS INTERSTITIAL LUNG DISEASE: A CASE OF ANCHORING BIAS DURING THE COVID-19 PANDEMIC

SESSION TITLE: Dyspne Mysteries SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 01:35 pm - 02:35 pm INTRODUCTION: Anti-synthetase (AS) syndrome is characterized by interstitial lung disease (ILD), arthritis, myositis, fever, or Raynaud's phenomenon in the presence of an AS autoantibody (1). At least 70% of patients with AS syndrome develop ILD (2), and it represents the major cause of mortality in these patients with a 10 year survival rate of 73%. In a small cohort study, the anti-PL-12 antibody subtype was found to be strongly associated with ILD (3). CASE PRESENTATION: A 35 year old female with a history of tobacco use disorder presented to the hospital with three months of recurrent subjective fevers, non-productive cough, and dyspnea on exertion. She denied arthralgias, muscle weakness and hemoptysis. She initially presented to her primary care physician with these symptoms and was prescribed amoxicillin for streptococcal pharyngitis. The patient continued to be symptomatic and was treated empirically for COVID-19 pneumonia twice despite two negative COVID-19 tests and without any significant clinical improvement in her respiratory status. On admission, she was febrile, tachycardic, and had a new oxygen requirement with bilateral coarse breath sounds on exam. She had no leukocytosis and her COVID-19 test was negative. CT angiography of the chest showed extensive mixed reticular and airspace opacities with peribronchial predilection and peripheral sparing (figure 1). A bronchial alveolar lavage was notable only for neutrophilia (19%) and eosinophilia (4%). Rheumatological workup revealed elevated rheumatoid factor, positive antinuclear antibody (1:40), weakly positive anti–Sjögren's-syndrome-related antigen A antibody (50 AU/ml), undetectable anti-Jo-1 antibody and positive anti-PL-12 antibody. Pulmonary function testing revealed a TLC of 40% and DLCO of 28%, consistent with a restrictive pattern. Considering the patient's organizing pneumonia, positive antibodies, and findings of "mechanic's hands,” the patient was diagnosed with anti-synthetase syndrome with ILD. She was started on oral prednisone and mycophenolate mofetil. On follow-up, she was noted to have symptomatic improvement and stable hypoxia without clinical signs of disease progression. DISCUSSION: During the coronavirus pandemic, the resemblance of COVID-19 pneumonia to other diseases, in the absence of conscious suspicion for other etiologies, can lead to anchoring and availability bias thereby delaying diagnosis and appropriate treatment. Additionally, anti-synthetase syndrome should be considered in the differential diagnosis of ILD even in the absence of arthritis and myositis, as respiratory symptoms are often the first presenting signs. CONCLUSIONS: Increased responsibility is required of diagnosticians to exercise due diligence and active recognition of COVID availability and anchor bias to avoid missing crucial diagnoses.
