RESUMEN
BACKGROUND: Streptococcal toxic shock syndrome (STSS) is a fulminant complication of predominantly invasive group A streptococcal infections. STSS is often characterized by influenza-like symptoms, including fever, chills, and myalgia that can quickly progress to sepsis with hypotension, tachycardia, tachypnea, and multiple organ failure (kidney, liver, lung, or blood). Mortality can exceed 50% depending on the severity of symptoms. CASE SUMMARY: Here, we describe a novel, multi-extracorporeal intervention strategy in a case of severe septic shock secondary to STSS. A 28-year-old woman 5 days after cesarean section developed STSS with respiratory distress, hypotension, and multiple organ failure. Despite conventional therapy with intubation, antibiotics, vasopressors, and fluid resuscitation, her condition worsened. She was placed on venoarterial extracorporeal membrane oxygenation (VA-ECMO) with subsequent initiation of pathogen hemoperfusion using the Seraph 100 blood filter, followed by immunomodulation with the selective cytopheretic device (SCD). No device-related adverse events were observed. The patient's condition gradually stabilized with discontinuation of vasopressors after 4 days, ECMO decannulation after 6 days, evidence of renal recovery after 7 days, and extubation from mechanical ventilation after 14 days. She was transferred to conventional hemodialysis after 13 days and discontinued all kidney replacement therapy 11 days later. CONCLUSIONS: This is the first reported use of VA-ECMO, Seraph 100 hemoperfusion, and cell-directed immunomodulation with SCD. This multimodal approach to extracorporeal support represents a promising therapeutic strategy for the most refractory critical care cases. Further studies are needed to assess the safety and efficacy of this sequential approach.
