Summary

Acute lymphoblastic leukaemia (ALL) patients are susceptible to Gram-negative infections. A rapidly progressing Escherichia coli hand infection in an ALL patient required amputation due to neutropenia.

Area of Science:

  • Oncology
  • Infectious Diseases
  • Hematology

Background:

  • Acute lymphoblastic leukaemia (ALL) is characterized by neutropenia, increasing susceptibility to bacterial infections.
  • Gram-negative bacilli, such as Escherichia coli, pose a significant infection risk in neutropenic patients.
  • Chemotherapy for ALL can exacerbate neutropenia, heightening infection risks.

Observation:

  • A case of cellulitis caused by Escherichia coli in the first web space of the hand is presented.
  • The infection occurred in a patient undergoing reinduction chemotherapy for ALL.
  • The cellulitis demonstrated rapid proximal extension.

Findings:

  • The severe, rapidly progressing infection necessitated a forequarter amputation.
  • Neutropenic patients exhibit a blunted inflammatory response, potentially masking early signs of infection.

  • Prompt recognition and intervention are critical in managing severe infections in neutropenic individuals.

    • Implications:

    • This case highlights the critical need for vigilant monitoring of infections in neutropenic patients.
    • Early and aggressive management strategies are essential to prevent severe complications.
    • Understanding the risks associated with Gram-negative infections in ALL patients is crucial for clinical practice.
