Abstract
A 41-year-old woman with a history of asthma presented to the emergency department with complaints of progressive malaise, dyspnea, vomiting, and diarrhea for a week. Upon presentation, the patient was hemodynamically unstable and exhibited severe respiratory distress. A chest computed tomography revealed consolidation of the left upper lobe with confluence in the left perihilar region and a left pleural effusion. The patient was admitted to the intensive care unit for further management of respiratory failure, and a chest tube was placed on the left side. Despite the absence of bacteremia, the diagnosis of Streptococcal toxic shock syndrome was confirmed through a pleural fluid culture positive for Streptococcus pyogenes and evidence of multiorgan failure. Her treatment included vasopressors, broad-spectrum antibiotics, and intravenous immunoglobulin. For renal failure, the patient required continuous renal replacement therapy. Despite all these interventions, the patient continued to decline, and left-sided video-assisted thoracoscopic surgery was pursued with subsequent improvement of her condition. The incidence of invasive Group A streptococcal disease is significant, with notable mortality and morbidity among affected patients. The rapid deterioration is thought to be secondary to the highly virulent nature of the pathogen and the production of superantigens. The rapid institution of adequate antibiotic coverage with beta-lactams and clindamycin has been shown to decrease the mortality rate. Intravenous immunoglobulin has also been included with a promising positive effect.
