Introduction

  • Syndrome of peracute, rapidly fatal, colitis and toxemia of unknown cause.
  • Cause: unknown. Clinically and pathologically similar to known causes of colitis, eg salmonellosis   Intestine: salmonellosis  and antibiotic-associated diarrhea   Diarrhea: antimicrobial associated  . Endotoxemia and gastrointestinal anaphylaxis may be involved.
  • Signs: rapid onset of severe diarrhea with endotoxemia, abdominal pain and tympany, and in some cases, sudden death.
  • Diagnosis: by exclusion of other cases of enterocolitis either pre- or post mortem.
  • Treatment: is similar to all other acute enterocolitis and centrally involves large volumes of intravenous fluids.

Pathogenesis

Etiology

  • Clostridium cadaveris,C. difficile  Clostridium difficile  ,C. perfringenstype A   Clostridium perfringens  have been implicated as causes   Gastrointestinal: clostridiosis  .
  • Endotoxemia and gastrointestinal anaphylaxis may be involved with an acute type I hypersensitivity localized in the GI tract associated with an underlying disorder of the large intestine.
  • Other factors may include previous stress and depressed host resistance.

Predisposing factors

General
  • Stress.
  • Depressed host resistance.

Pathophysiology

  • Peracute fulminant colitis and toxemia which is often fatal.
  • Diarrhea results from intestinal inflammation and possibly type I hypersensitivity   →   increased mucosal secretory activity and intramural edema.
  • Endotoxemic   Endotoxemia: overview  and septic shock may supervene with infarction of intestinal segments due to intravascular coagulation.
