“…Empyema caused by the SAG can infect the lungs through aspiration of oral secretions, direct transmission by trauma or surgery, transmission from surrounding tissues, and blood circulation from other parts of the body [8] . Pneumonia, thoracic surgery, malignancy, diabetes, neurologic disease, alcohol abuse, and mucosal damage (sinusitis and periodontal disease) are known risk factors for empyema [9,10] . Traditionally, the most predominant factor has been assumed to be bacterial pneumonia, but the bacterial etiology of empyema is not necessarily similar to that of pneumonia.…”

Rationale:Empyema caused by Streptococcus constellatus is rare in patients without underlying diseases. However, the importance of the Streptococcus anginosus group, which consists of S constellatus, S anginosus, and Streptococcus intermedius, as causative organisms of empyema has been increasing.Patient concerns:A 78-year-old man initially presented with dyspnea and chills for 4 days. He had no medical history.Diagnosis:Chest X-ray and chest computed tomography showed a large and multiloculated pleural effusion with an air bubble on the right side. Cultivation of the pleural effusion using clone library analysis of the 16S rRNA gene revealed S constellatus positivity.Interventions:The patient was treated by drainage of the pleural effusion and intravenous ceftriaxone and clindamycin for the possibility of anaerobes, followed by 10 weeks of oral antibiotics.Outcomes:On the 11th day of admission, the thoracic drainage tube was removed. After 1 year of treatment, there were no sequelae of empyema.Lessons:Although S constellatus can cause serious infections in patients with underlying diseases and immunosuppression, physicians need to consider S constellatus infection in community-acquired empyema in elderly individuals. It should be treated with early pleural drainage and antibiotics to avoid surgical decortication and prolonged hospitalization.

“…Although, the incidence of SAG-related empyema is low, it remains to have high rate of morbidity and mortality rates. Therefore, it is important for clinicians to recognize how it can present to be able to provide timely diagnosis and management with antibiotics, drainage, or surgery to avoid dire outcomes [9].…”

“…The child only showed good clinical and radiological evolution after a thoracoscopic intervention and despite appropriate antibiotic therapy, demonstrating the importance of surgery in these cases. 6,14,15 Empyema in the fibrinopurulent or organizing stage should be considered an indication for surgical management. 16 The antibiotic course is usually long, with a mean duration of up to 34 days, and most SAG isolates seem to be sensitive to penicillin and cefotaxime, 10,17,18 like in our case report.…”

Objective: To highlight the pathogenicity of Streptococcus anginosus, which is rare in pediatric patients, but can cause severe infections that are known to have a better outcome when treated early with interventional procedures and prolonged antibiotic therapy. Case description: The patient is a 6-year-old boy with global developmental delay, examined in the emergency room due to fever and respiratory distress. The physical examination and diagnostic workout revealed complicated pneumonia with empyema of the left hemithorax; he started antibiotic therapy and underwent thoracic drainage. Pleural fluid cultures grew Streptococcus anginosus. On day 11, the child had a clinical deterioration with recurrence of fever, hypoxia, and respiratory distress. At this point, considering the causative agent, he was submitted to video-assisted thoracoscopic decortication, with good progress thereafter. Comments: Streptococcus anginosus is a commensal bacterium of the human oral cavity capable of causing severe systemic infections. Although reports of complicated thoracic infections with this agent are rare in the pediatric population, they have been increasing in adults. Streptococcus anginosus has a high capacity to form abscess and empyema, requiring different therapeutic approaches when compared to complicated pneumonia caused by other agents. Objetivo: Alertar para a patogenicidade do Streptococcus anginosus que, apesar de raro em pediatria, pode causar infeções graves que necessitam de tratamento invasivo e antibioterapia de longo curso para obter um melhor prognóstico. Descrição do caso: Criança de seis anos, com atraso do desenvolvimento psicomotor, avaliado no serviço de urgência por febre e dificuldade respiratória. O exame físico, juntamente com os exames complementares, revelou uma pneumonia complicada com empiema no hemitórax esquerdo, tendo iniciado antibioterapia e sido submetido à drenagem do líquido pleural. Foi identificado Streptococcus anginosus nesse líquido. No 11º dia de doença, a criança agravou o seu estado clínico, com recidiva da febre, hipoxemia e dificuldade respiratória. Considerando-se o microrganismo identificado, o paciente foi submetido à decorticação pulmonar por videotoracoscopia, com boa evolução clínica posterior. Comentários: Streptococcus anginosus é uma bactéria comensal da cavidade oral humana, que pode causar infecções sistêmicas graves. Apesar de serem raros os casos descritos em pediatria, têm sido cada vez mais descritas infecções torácicas complicadas em adultos. Esse microrganismo também tem a capacidade de formar abcessos e empiemas, que precisam de intervenções terapêuticas diferentes, quando comparados a pneumonias complicadas causadas por outros agentes. Palavras-chave: Pneumonia bacteriana; Empiema pleural; Streptococcus anginosus; Cirurgia torácica por videotoracoscopia. ABSTRACTRESUMO
