Necrotizing fasciitis, The Flesh Eating Disease

Yesterday, MPW received a prayer request for 2 year old Grace who has Necrotizing Fasciitis, The Flesh Eating Disease. Please be in Pray for her and her family. Although this disease is still consider rare, ever since my Mother-in-law went through this a few years back, I hearing about more and more cases of it.

Necrotizing fasciitis or fasciitis necroticans, commonly known as “flesh-eating bacteria,” is a rare infection of the deeper layers of skin and subcutaneous tissues, easily spreading across the fascial plane within the subcutaneous tissue. Many types of bacteria can cause necrotizing fasciitis.

The infection begins locally, at a site of trauma, which may be severe (such as the result of surgery), minor, or even non-apparent. The affected skin is classically, at first, very painful without any grossly visible change. With progression of the disease, tissue becomes swollen, often within hours. Diarrhea and vomiting are common symptoms as well. Inflammation does not show signs right away if the bacteria is deep within the tissue. If it is not deep, signs of inflammation such as redness and swollen or hot skin show very quickly. Skin color may progress to violet and blisters may form, with subsequent necrosis (death) of the subcutaneous tissues. Patients with necrotizing fasciitis typically have a fever and appear very ill. More severe cases progress within hours, and the mortality rate is high, about 30%. Even with medical assistance, antibiotics take a great deal of time to react to the bacteria, allowing the infection to progress to a more serious state.

The diagnosis is confirmed by either blood cultures or aspiration of pus from tissue, but early medical treatment is crucial and often presumptive; thus, antibiotics should be started as soon as this condition is suspected. Initial treatment often includes a combination of intravenous antibiotics including penicillin, vancomycin and clindamycin. If necrotizing fasciitis is suspected, surgical exploration is always necessary, often resulting in aggressive debridement (removal of infected tissue). As in other maladies characterized by massive wounds or tissue destruction, hyperbaric oxygen treatment can be a valuable adjunctive therapy, but is not widely available. Amputation of the affected organ(s) may be necessary. Repeat explorations usually need to be done to remove additional necrotic tissue. Typically, this leaves a large open wound which often requires skin grafting. The associated systemic inflammatory response is usually profound, and most patients will require monitoring in an intensive care unit.
