Clostridium septicum infection associated with colonic carcinoma and hematologic abnormality
Insights
Clostridium septicum sepsis can indicate underlying colon tumors, particularly in the cecum. Prompt antibiotic treatment is crucial for sepsis, and barium-enema examinations are recommended for patients with positive anaerobic cultures.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Oncology
Background:
- Clostridium septicum is an anaerobic bacterium that can cause severe infections, including sepsis and gas gangrene.
- Sepsis associated with C. septicum is rare but carries a high mortality rate.
- The presence of C. septicum in blood cultures suggests a potential link to underlying gastrointestinal pathology.
Observation:
- A two-year retrospective study at Duke University Medical Center identified six patients with C. septicum sepsis.
- Three patients presented with hematologic disorders, and three had concurrent colon tumors.
- Gas gangrene was a complication in two patients requiring limb disarticulation for management.
Findings:
- Three patients with C. septicum sepsis died, while three survived.
- Survival was achieved in two patients after surgical intervention (arm disarticulation) for gas gangrene.
- One patient survived sepsis but succumbed to metastatic colon cancer, highlighting the oncologic association.
Implications:
- Positive anaerobic blood cultures for C. septicum warrant immediate antibiotic administration.
- The high association with colon tumors, especially in the cecum, necessitates prompt investigation with barium-enema examinations.
- Early recognition and management of C. septicum sepsis, alongside investigation for underlying malignancy, are critical for patient outcomes.
Abstract:
Six patients with Clostridium septicum sepsis seen at Duke University Medical Center over a two-year period also had other abnormalities, consisting of hematologic disorders in 3 and colon tumors in 3. Three patients died of sepsis; 2 survived following disarticulation of the arm to control gas gangrene, while the sixth patient survived the sepsis but died of metastatic disease. When anaerobic cultures are positive for C. septicum, antibiotics should be given immediately. The high incidence of underlying colon tumor, especially in the cecum, should prompt consideration of a barium-enema examination.
