Abstract:
We report a 35-year-old man with systemic lupus erythematosus and an associated protein-losing enteropathy that was most likely due to mesenteric venulitis or thrombosis. Evaluation of the patient's intestinal abnormality was aided by the use of magnifying endoscopy; the duodenal villi were lustrous and swollen and of various size, a pattern different from that previously described for intestinal lymphangiectasia. The patient was treated with corticosteroids, resulting in a good clinical response and return of the villi to normal shape and size.
Insights
Systemic lupus erythematosus can cause protein-losing enteropathy due to mesenteric venulitis. Corticosteroid treatment effectively resolved the condition and restored normal duodenal villi structure.
Area of Science:
- Gastroenterology
- Rheumatology
- Pathology
Background:
- Systemic lupus erythematosus (SLE) is a chronic autoimmune disease.
- Protein-losing enteropathy (PLE) is a rare complication of SLE.
- Mesenteric venulitis or thrombosis are potential causes of SLE-associated PLE.
Observation:
- A 35-year-old male patient with SLE presented with PLE.
- Magnifying endoscopy revealed lustrous, swollen duodenal villi of varying sizes.
- This villous morphology differed from typical intestinal lymphangiectasia.
Findings:
- The patient's PLE was likely caused by mesenteric venulitis or thrombosis.
- Corticosteroid therapy led to a significant clinical improvement.
- Duodenal villi returned to normal morphology following treatment.
Implications:
- This case highlights mesenteric venulitis/thrombosis as a cause of PLE in SLE.
- Magnifying endoscopy is a valuable tool for diagnosing intestinal abnormalities in SLE.
- Corticosteroids are an effective treatment for this specific SLE complication.
