[Invasive Eyelid Infections by β-Hemolytic Streptococci of Serogroup A].

BACKGROUND

Invasive soft tissue infections by Streptococcus pyogenes are rapidly progressive and potentially life-threatening infectious diseases. These can also affect the eyelid. Aggressive virulence factors and the synthesis of exotoxins can lead to complications, such as periorbital necrotizing fasciitis (PONF) and streptococcal toxic shock syndrome (STSS). The clinical picture is characterized by four patients with invasive eyelid infections.

MATERIALS AND

METHODS

Photographic documentation, radiological imaging, laboratory and smear diagnostics and intravenous antibiotic therapy were performed on all patients according to the recommendations of the German Robert Koch Institute and the local infectiology board.

RESULTS

In all patients, Streptococcus pyogenes was culturally detected in a direct swab. The antibiogram showed sensitivity to the common intravenous antibiotics. The time interval between symptom onset and presentation at the clinic was between two days and one week. All patients had high systemic inflammatory parameters on admission: Pat. 1: CRP 259 mg/l, leukocytes 20.1 giga/l; Pat. 2: CRP 375 mg/l, leukocytes 15.6 giga/l; Pat. 3: CRP 378 mg/l, leukocytes 38.7 giga/l; Pat. 4: CRP 483 mg/l, leukocytes 1.7 giga/l; normal values: CRP < 5 mg/l, leucocytes 4.4 - 11.3 giga/l. In Pat. 2 and 3, a periorbital necrotizing fasciitis was diagnosed due to rapidly progressing necrosis in the area of cutis and subcutis and systemic toxicity. Pat. 3 and 4 met the diagnostic criteria of STSS. Pat. 2, 3 and 4 had to be relocated to an intermediate or intensive care unit with sepsis, despite immediate intravenous antibiotic therapy. Patient 3 underwent surgical debridement during the stay in the intensive care unit. Thanks to interdisciplinary management (ophthalmology, infectiology, ear, nose and throat medicine, internal medicine and intensive care medicine), all patients were finally discharged from our inpatient treatment in a significantly improved general condition.

CONCLUSION

Invasive streptococcal infections represent a challenge in the daily routine of an ophthalmologist. Interdisciplinary management and immediate onset of high-dose intravenous antibiotic therapy are crucial for successful treatment.
