From the Guidelines

Treatment for Verocytotoxin-producing Escherichia coli (VTEC) infection should focus on supportive care, avoiding antimotility agents and antibiotics, which may worsen the risk of hemolytic uremic syndrome (HUS) 1.

Overview of VTEC Infection Treatment

The primary goal in managing VTEC infections is to provide supportive care, ensuring the patient remains hydrated and comfortable while the infection runs its course. This approach is based on the understanding that interventions like antibiotics can potentially increase the production of Shiga toxin, thereby elevating the risk of developing HUS, a severe complication of VTEC infection 1.

Supportive Care Measures

  • Hydration: Encourage oral rehydration with solutions like Pedialyte or sports drinks for mild to moderate dehydration. For severe cases, intravenous fluids may be necessary.
  • Pain Management: Acetaminophen (500-1000mg every 6 hours, not exceeding 4000mg daily) is recommended for pain relief. Nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided due to their potential to worsen kidney function.
  • Diet: A temporary bland diet can help manage symptoms. Patients should avoid spicy, fatty, or high-fiber foods.
  • Rest: Adequate rest is crucial for recovery.
  • Hand Hygiene: Strict handwashing practices are essential to prevent the spread of the infection.

Monitoring for Complications

Close monitoring for signs of HUS or other complications is critical. This includes watching for decreased urine output, unusual bleeding, or extreme fatigue. Any of these symptoms warrant immediate medical attention.

Avoidance of Certain Treatments

  • Antimotility Agents: These should be avoided due to the risk of worsening the infection 1.
  • Antibiotics: The use of antibiotics in VTEC infections is controversial and generally not recommended due to the potential risk of increasing toxin production and thereby the risk of HUS 1.

Duration of Illness

VTEC infections typically resolve within 5-10 days without specific antimicrobial treatment. The focus should remain on supportive care and monitoring for potential complications.

By prioritizing supportive care and avoiding potentially harmful interventions, the risk of morbidity and mortality associated with VTEC infections can be minimized, improving the quality of life for affected individuals.

From the Research

Treatment Overview

The treatment for Verocytotoxin-producing Escherichia coli (VTEC) infection is primarily focused on supportive care, as there is no consensus on the use of antibiotic therapy 2, 3, 4.

Supportive Care

  • The management of Hemolytic Uremic Syndrome (HUS), a complication of VTEC infection, includes the usual treatment of children with Acute Kidney Injury (AKI) 2.
  • Transfusion with packed red blood cells may be necessary in cases of severe anemia, while platelet transfusions are limited to surgical procedures or active bleeding 2.
  • Treatment with plasma and/or plasma exchange has not been proven beneficial in STEC-HUS 2.
  • Eculizumab has been used for the treatment of STEC-HUS, but its value remains to be determined 2.

Antibiotic Therapy

  • The use of antibiotics in VTEC infection is controversial, with some studies suggesting an increased risk of developing HUS 3, 4.
  • Certain antibiotics, such as DNA synthesis inhibitors, should be avoided, while protein and cell wall synthesis inhibitors may reduce the release of toxins from VTEC isolates 4.
  • A systematic review proposes that antibiotic treatment with protein and cell wall synthesis inhibitors can be considered when specific criteria are met 4.

Environmental Prevention

  • Environmental prevention strategies, such as animal- and meat-handling practices, can help reduce the transmission of VTEC from animal carriers to humans 5.

Asymptomatic Carriers

  • Antimicrobial treatment of asymptomatic carriers of VTEC has been successful in eradicating the bacteria without complications 6.
