DefinitionThis section has been translated automatically.
Rare, life-threatening, fulminant, deep, phlegmonous infection of the skin, subcutis and fascia, possibly also of the musculature, often occurring after banal injuries, no bone involvement (Goh T et al.2014).

PathogenThis section has been translated automatically.
On the basis of the detected excitation spectrum 4 types can be distinguished:
- Type 1: Polymicrobial mixed infection. Mixed infection mostly combinations of different anaerobic bacteria (e.g. Bacteroides, Peptostreptococcus spp.) and facultatively anaerobic bacteria (e.g. Non-A-Streptococcus) and Enterococci (e.g. E. coli, Enterobacter, Klebsiella, Proteus).
- Type 2: Group A streptococci (Streptococcus pyogenes) with or without concomitant infection by Staphylococcus aureus or epidermidis.
- There are also isolated reports of infections with multi-resistant germs such as Acinobacter baumannii, an opportunistic Gram-negative, coccoid rod bacterium.
- Type 3 (rare): Vibrio spp.
- Type 4 (rare): Candida spp.
Occurrence/EpidemiologyThis section has been translated automatically.
Low incidence; figures of 0.4/100,000 inhabitants are given for Europe. m:w=2-3:1;
EtiopathogenesisThis section has been translated automatically.
Mostly after banal injuries, but also after surgical wounds or injuries with infected hypodermic needles of drug addicts. Bacterial toxins or the deposition of bacterial and cellular decay products in the event of inadequate removal are held responsible for the necrotizing course of the disease.
LocalizationThis section has been translated automatically.
Extremities, especially lower legs, also forearms starting from the back of the hand. Furthermore lower abdomen, genital area ( Gangraena acuta genitalium).
Clinical featuresThis section has been translated automatically.
Start with high septic temperatures (80%), severe disturbance of the general findings and severe local pain (79%). Pain in the early stages often appears disproportionately severe in view of the low or absence of visible skin lesions.
The skin initially shows a circumscribed, overheated redness (80%) with swelling and subsequently a subcutaneous nodular, almost board-like, painful induration.
Rapid transition to haemorrhagic infarction of the subcutis, secondarily also of the fascia and the musculature (compartment syndrome); in surgical intervention, a muscle melting under the hands is found. In this stage the skin appears bluish-livid, large blistered and lifted.
Note: Diabetes mellitus (detected in about 45% of cases), glucocorticoid therapy, alcoholism, intravenous drug abuse, liver cirrhosis and tumor diseases are considered risk factors (Goh T et al. 2014).
Note: A special form of necrotizing fasciitis affecting the scrotum or vulva is Fournier's gangrene.
LaboratoryThis section has been translated automatically.
Inflammation parameters (CRP, BSG) massively increased, leucocytosis, neutrophilia; CK, amylase increased.
Draw blood cultures!
DiagnosisThis section has been translated automatically.
Clinic, laboratory, sonography of the affected muscle boxes, MRI.
Complication(s)This section has been translated automatically.
TherapyThis section has been translated automatically.
Combination of radical surgical debridement with removal of fascia and infected soft tissue. Immediate broad surgical opening, extended debridement of the necrotic area to the point where skin and subcutaneous tissue cannot be separated from the fascia. Removal of necrotizing parts, cleaning of the wound bed, open wound treatment. Another revision ("second look") should be performed 24-36 hours for possible resection and wound irrigation. In addition, high-dose antibiotic therapy with broad-spectrum antibiotics such as piperacillin and tazobactam or with reserve antibiotics such as carbapenem should be administered. Antibiotic therapy alone is usually not sufficient!
Internal therapyThis section has been translated automatically.
- High-dose parenteral antibiotic therapy as soon as possible after the antibiogram. Take multiple wound swabs and prepare blood cultures! Information to the laboratory, 3 times 2 venous blood cultures per 24 hours are sufficient for pathogen detection.
- The standard therapy consists of a combination of penicillin G and an aminoglycoside (gentamicin), since a synergistic effect of both substances is achieved even if pathogens are not very sensitive to aminoglycosides alone. Penicillin G 5 million IU at TD of 20-30 million IU, gentamicin (e.g. Refobacin) 3-5 mg/kg bw/day in 1 ED slow i.v. (short infusion). In case of detection of anaerobes additionally clindamycin (e.g. sobelin) 4 times/day 300-600 mg (up to 3 times/day 600 mg) i.v. In case of penicillin intolerance vancomycin 2 times/day 1 g or 4 times/day 500 mg i.v.v. (1 hour infusion) or teicoplanin (e.g. Targocid) 400 mg on day 1, followed by 200 mg i.v. once/day from day 2. The duration of therapy must be adapted to clinical conditions. Alternatively linezolid (Zyvoxide) 2 times/day 600 mg i.v.
- The administration of glucocorticoids is assessed differently. While glucocorticoids are sometimes accused of playing a role in the pathogenesis of the disease pattern, other authors consider their inhibitory effect on the tumor necrosis factor and the resulting stabilization of the cell membrane to be a potentially life-saving factor.
Progression/forecastThis section has been translated automatically.
Lethal outcome in up to 30% of cases (sepsis).
