A26.7 Erysipelothrix sepsis

Name of the Condition

• Erysipelothrix sepsis

Summary

Erysipelothrix sepsis is a systemic bacterial infection caused by Erysipelothrix rhusiopathiae. It occurs when the bacterium enters the bloodstream, leading to widespread infection. The condition typically follows exposure to contaminated animal products or environments and may present with systemic symptoms, including fever, chills, and organ involvement. Sepsis from this organism is less common than localized cutaneous infections but can be severe.

Causes

Erysipelothrix sepsis is caused by the bacterium Erysipelothrix rhusiopathiae. Infection occurs through direct contact with infected animals, animal products (such as meat, fish, or hides), or contaminated soil or water. The bacteria enter the body through minor cuts, abrasions, or mucous membranes, spreading to the bloodstream and causing systemic infection. This can result from untreated localized infections or direct exposure to high bacterial loads.

Risk Factors

• Occupational exposure to raw meat, fish, or animal products (e.g., butchers, fishermen, veterinarians).
• Handling of contaminated materials without protective measures.
• Pre-existing skin injuries or breaks that facilitate bacterial entry.
• Contact with environments where the bacterium is prevalent (e.g., farms, slaughterhouses).
• Weakened immune systems, which may increase susceptibility to systemic spread.

Symptoms

• Fever, chills, and generalized malaise.
• Rapid heart rate and breathing.
• Low blood pressure or signs of shock.
• Possible involvement of internal organs (e.g., heart, liver, or kidneys).
• Skin lesions or localized infections may be present but are not always evident.

Diagnosis

Diagnosis is based on clinical presentation, including systemic signs of infection, and confirmed by laboratory testing. Blood cultures are essential to identify Erysipelothrix rhusiopathiae. Additional tests, such as imaging or organ function studies, may be used to assess the extent of organ involvement. Clinical history of exposure to contaminated animal products or environments supports the diagnosis.

Treatment Options

Treatment involves prompt administration of appropriate antibiotics, such as penicillin or erythromycin, to target Erysipelothrix rhusiopathiae. Supportive care, including intravenous fluids and monitoring of vital signs, is critical for managing sepsis. In severe cases, intensive care may be required to address organ dysfunction or shock. Early intervention improves outcomes.

Prognosis and Follow-Up

Prognosis depends on the severity of infection and timeliness of treatment. With prompt antibiotic therapy and supportive care, recovery is possible. However, sepsis can be life-threatening, particularly in immunocompromised individuals. Follow-up care includes monitoring for recurrence, assessing organ function, and ensuring complete resolution of infection. Long-term complications may occur in severe cases.

Complications

• Septic shock, a life-threatening drop in blood pressure.
• Multi-organ failure, affecting the heart, lungs, or kidneys.
• Secondary infections due to weakened immune response.
• Chronic health issues from prolonged organ damage.

Lifestyle & Prevention

• Use protective gear (gloves, aprons) when handling raw meat or animal products.
• Clean and disinfect work surfaces and tools regularly.
• Avoid contact with contaminated soil or water if possible.
• Seek prompt treatment for skin injuries to prevent bacterial entry.
• Maintain good hygiene practices, especially after handling animals or animal products.

When to Seek Professional Help

Seek immediate medical attention if you experience fever, chills, rapid heartbeat, or low blood pressure after exposure to animal products or environments. These symptoms may indicate sepsis and require urgent evaluation. Early intervention is critical to prevent severe complications.

Tips for Medical Coders

Code A26.7 is used for Erysipelothrix sepsis. Documentation should specify the presence of systemic infection, including clinical signs (e.g., fever, hypotension) and laboratory confirmation (e.g., blood cultures). Ensure the diagnosis aligns with the criteria for sepsis and not localized cutaneous infection. Review clinical notes for exposure history and treatment details to support accurate coding.
