Abstract:
Extra-meningeal and non-cutaneous manifestations of meningococcal infection are well recognized but rare. Herein we report a little recognized complication of meningococcaemia, namely late-onset gastrointestinal vasculitis. In the case presented, the prostacycline analogue iloprost was used in an attempt to minimize incipient digital gangrene ina patient with evidence of protracted immunological phenomena. In addition, diclofenac was used to treat severe arthralgia. Withdrawal of iloprost on day 19 was associated with abdominal pain and peritonism. Laparotomy demonstrated ischaemia and ulceration in the caecum, and histology revealed full thickness mucosal ulceration with a prominent vasculitic process. It is postulated that these findings were immunologically mediated, with possible rebound vasoconstriction following withdrawal of iloprost. It is also possible that NSAID use contributed to the findings via cyto-toxicity to mucosal cells.
Insights
Late-onset gastrointestinal vasculitis is a rare complication of meningococcaemia (meningococcal infection). This case suggests it may be immunologically mediated, potentially triggered by medication withdrawal or NSAID use.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Immunology
Background:
- Meningococcal infection (meningococcaemia) typically presents with meningitis or sepsis.
- Extra-meningeal and non-cutaneous manifestations are recognized but uncommon.
- Late-onset complications require further investigation.
Observation:
- A patient with meningococcaemia developed digital gangrene and immunological phenomena.
- Treatment included iloprost (a prostacycline analogue) and diclofenac (a nonsteroidal anti-inflammatory drug).
- Withdrawal of iloprost led to abdominal pain and peritonism.
Findings:
- Laparotomy revealed caecal ischemia and ulceration.
- Histology confirmed full-thickness mucosal ulceration with vasculitis.
- The vasculitic process is postulated to be immunologically mediated.
Implications:
- This case highlights late-onset gastrointestinal vasculitis as a rare complication of meningococcaemia.
- Potential triggers include immunological phenomena, rebound vasoconstriction after iloprost withdrawal, or NSAID-induced cytotoxicity.
- Further research is needed to understand the mechanisms and management of this complication.
