Vibrio Infections Treatment & Management
- Author: Hoi Ho, MD; Chief Editor: Burke A Cunha, MD more...
Medical Care
Medical care depends on the clinical presentation and the presence of underlying medical conditions.
- Gastroenteritis
- Because Vibrio gastroenteritis is self-limited in most patients, no specific medical therapy is required. Patients who cannot tolerate oral fluid replacement may require intravenous fluid therapy.
- Although most Vibrio species are sensitive to antibiotics such as doxycycline or quinolones, antibiotic therapy does not shorten the course of the illness or the duration of pathogen excretion. However, if the patient is ill and has a high fever or an underlying medical condition, oral antibiotic therapy with doxycycline or quinolone can be initiated.
- Patients with noncholera Vibrio wound infection or septicemia are much more ill and frequently have other medical conditions. Medical therapy consists of the following:
- Prompt initiation of effective antibiotic therapy
- Intensive medical therapy with aggressive fluid replacement and vasopressors for hypotension and septic shock to correct acid-base and electrolytes abnormalities that may be associated with severe sepsis
Surgical Care
- Early fasciotomy within 24 hours after development of clinical symptoms can be life saving in patients with necrotizing fasciitis.
- Early debridement of the infected wound has an important role in successful therapy and is especially indicated to avoid amputation of fingers, toes, or limbs.
- Expeditious and serial surgical evaluation and intervention are required because patients may deteriorate rapidly, especially those with necrotizing fasciitis or compartment syndrome.
- Reconstructive surgery, such as skin graft, is indicated in the recovery phase.
Consultations
A team effort is required to ensure successful therapy in patients with noncholera Vibrio wound infection or septicemia.
- Urgent consultation with an infectious diseases specialist for diagnosis and possible investigation of foodborne illness
- Urgent consultation with a general surgeon or orthopedist for debridement
- Consultation with a critical care specialist to manage possible developments such as severe sepsis, septic shock, and multiple organ dysfunction (eg, ARDS, renal failure)
- Consultation with a gastroenterologist since many patients with Vibrio infections have advanced liver disease and may develop serious complications such as gastrointestinal bleeding
Diet
- Patients with Vibrio gastroenteritis are permitted oral intake as tolerated.
- Patients with Vibrio wound infection and septicemia are frequently too ill to tolerate oral intake during the acute phase.
- Some patients with advanced liver disease develop hepatic encephalopathy and may require oral or parenteral hepatic nutrition.
