Gas Gangrene (myositis or myonecrosis)

Definition and Causes

Gas gangrene, also called clostridial myositis or myonecrosis, is a severe and rapidly spreading infection of muscle and other soft tissue. The bacteria that cause gas gangrene, of the species clostridium, most commonly Clostridium perfringens, produce liquid and gaseous poisons (toxins) that inflame (myositis) or kill (myonecrosis) healthy tissue. The advancing infection can threaten life and limb in mere hours.

Flesh-eating clostridium and other bacteria may originate in the gut, contaminated food, surgical incisions, community and healthcare environments, or soil embedded in traumatic wounds and bone fractures. The microorganisms surround themselves with toxins (alpha- or α-toxins) that interfere with the body’s natural immune response. Stopping toxin production as soon as possible is essential to prevent tissue loss, amputation, shock, and death.

Treatment with Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy, combined with antibiotics and surgical removal of dead tissue, is an effective treatment for gas gangrene. Clostridia are anaerobic, meaning they thrive in low-oxygen environments. HBOT stops toxin production and inhibits bacteria from replicating and spreading. Hyperbaric oxygen may also boost the effect of antibiotics, enhance the body’s natural defenses against bacteria, and help resolve or delay the onset of sepsis, a deadly blood poisoning.

hyperbariclink commentary

Clostridium perfringens is not to be confused with antibiotic-resistant Clostridium difficile (C. diff), an increasingly common source of healthcare-associated infections (HAIs). Gas gangrene does not involve C. diff. Nor can we find any good clinical evidence on the treatment of C. diff with hyperbaric oxygen. But early treatment of gas gangrene with hyperbaric oxygen, surgical debridement, and antibiotics combined has been shown to stop toxin production and significantly reduce mortality and morbidity compared with surgery alone. Do not expect further study. It may be considered unethical to conduct clinical trials on such gravely ill patients in critical need of standard combination therapy with HBOT.

Patient Resources

HyperbaricLink recommends the following websites for anyone seeking authoritative information, patient advocacy, and community support for gas gangrene.

Centers for Disease Control and Prevention (CDC)
US Department of Health and Human Services (HHS)

The CDC is dedicated to protecting health and promoting quality of life through the prevention and control of disease, injury, and disability. Its programs reduce the health and economic consequences of the leading causes of death and disability. The CDC website includes an informative page on Clostridium perfringens
infections.

US Food and Drug Administration (FDA)

The FDA website (www.fda.gov) puts Clostridium perfringens in its Bad Bug Book (BBB) as one of the most commonly reported causes of foodborne illnesses, with 10-12 outbreaks and over 10,000 individual cases every year.

MedlinePlus

A service of the US National Library of Medicine and the National Institutes of Health, MedlinePlus offers plenty of helpful links from its easy-to-read article on bacterial infections and gangrene.

PubMed Health

Another service of the US National Library of Medicine and the National Institutes of Health, PubMed Health offers shorter pages (with lots of links) on necrotizing soft tissue infection and gangrene.

US Department of Health and Human Services (HHS)

HHS.gov offers healthcare professionals and patients and families an excellent interactive video program, Partnering to Heal about preventing healthcare-associated infections (HAIs).

Wikipedia

The gas gangrene and Clostridium perfringens entries in Wikipedia provide some basic information about gangrene, with excellent microscopy and clinical photography.
