What Researchers Did
Researchers conducted a single-center retrospective case series at the University Hospital of Copenhagen, reviewing 11 adult patients with culture-confirmed periorbital Group A streptococcus infections over a 14-month period.
What They Found
The study included 11 patients with periorbital GAS infections, with a median age of 72 years; four patients had diabetes and two developed septic shock. Six cases were diagnosed with pre-septal cellulitis, while five had post-septal necrotizing soft tissue infection (NSTI) confirmed by surgery, with these NSTI cases showing the MLST 28 / emm 1.0 (M1 clone) GAS type.
What This Means for Canadian Patients
Canadian clinicians should maintain a high index of suspicion for Group A streptococcus in patients presenting with severe periorbital infections, especially given the post-COVID-19 surge. Early recognition and appropriate treatment, including surgical debridement for necrotizing soft tissue infection, are crucial to improve outcomes for Canadian patients.
Canadian Relevance
This study has no direct Canadian connection as it was conducted at a single center in Copenhagen, Denmark.
Study Limitations
The study's retrospective, single-center design and small sample size limit the generalizability of its findings.
