Insights
Cholesterol crystal embolism (CCE) frequently affects the digestive system, often presenting with abdominal pain and GI bleeding. Early consideration of CCE is crucial in patients with atherosclerosis and recent vascular procedures.
Area of Science:
- Cardiovascular Medicine
- Gastroenterology
- Pathology
Background:
- Cholesterol crystal embolism (CCE) is a systemic condition affecting multiple organs.
- The digestive system is the third most commonly affected system in CCE but is underrepresented in medical literature.
- This study aims to clinically characterize digestive system involvement in CCE.
Observation:
- A 7-year review identified 14 CCE cases, with 5 (36%) involving the digestive system.
- All affected patients had established atherosclerosis; precipitating factors included vascular manipulations or anticoagulation.
- Manifestations ranged from acute multiorgan failure to chronic gastrointestinal (GI) disease.
Findings:
- Common GI symptoms included abdominal pain, GI bleeding, fever, and diarrhea.
- Pathological findings involved bowel infarction, mucosal ulcerations, hepatocellular dysfunction, and pancreatitis.
- CCE presents with diverse clinical manifestations, impacting the GI tract significantly.
Implications:
- CCE should be considered in gastroenterological patients with atherosclerosis, especially after vascular procedures or anticoagulation.
- Recognizing CCE's GI manifestations can lead to earlier diagnosis and management.
- Further research is needed to fully understand CCE's impact on the digestive system.
Abstract:
In the 1359 published patients with multiorgan cholesterol crystal embolism (CCE), the digestive system seems to be the third most frequently affected system. Yet, this system received hitherto only little attention in the medical literature. Therefore, the aim of the present study was to clinically characterize the subset of patients with CCE involving the digestive system, based on our institutional experience and a review of the literature. Cases with CCE in a 7-yr period (1995-2001) were sought in the computerized records of our medical center. Of the CCE patients, those with digestive system involvement that could be related to CCE were included in this study. The clinical features of CCE were determined and compared with those found in published series. Fourteen cases with CCE were identified, giving an annual incidence of 0.8 per 10(5). Digestive system involvement was found in five (36%) of the 14 patients. All five patients had established atherosclerosis. Precipitating factors were vascular manipulations or anticoagulation treatment in four of these five patients. Two patterns of disease appeared: acute catastrophic multiorgan disorder with poor prognosis and chronic and more indolent GI disease. Abdominal pain, GI bleeding, fever, and diarrhea were the most common manifestations, resulting from bowel infarction, mucosal ulcerations, hepatocellular liver disorder, and/or pancreatitis. CCE is a systemic disorder with a frequent involvement of the digestive system and protean clinical manifestations. It should, therefore, be considered in any gastroenterological patient with atherosclerosis and recent vascular manipulations or systemic anticoagulation.
