Streptococcal Toxic Shock Syndrome Following Intestinal Obstruction in a Patient With Crohn’s Disease

Streptococcal toxic shock syndrome (STSS) is a rare, life-threatening complication of invasive group A streptococcal (iGAS) infections. We report the case of a 24-year-old woman with Crohn's disease receiving immunosuppressive therapy who developed STSS following intestinal obstruction. On day 2, she developed fever, altered mental status, hypoxemia, erythema, and hypotension. Chest CT revealed bilateral pulmonary infiltrates, and blood cultures grew emm1-positive M1UK Streptococcus pyogenes, confirming STSS. Early multidisciplinary intervention resulted in rapid recovery without sequelae. This case emphasizes the importance of considering iGAS-induced STSS in septic shock, especially in immunocompromised patients, and highlights the need for prompt recognition and treatment.
