Background:
Constrictive pericarditis (CP) represents a rare cause of protein-losing enteropathy (PLE) resulting from intestinal lymphangiectasia (IL). In this report, we describe an 8-year-old Turkish boy with IL and PLE secondary to CP.
Methods:
The boy was introduced to our clinic due to bilateral pretibial edema and swelling of the eyelids caused by hypoproteinemia. Physical examination revealed a distended right jugular vein. Laboratory investigation revealed PLE with fecal concentration of alpha-1 antitripsin of 4.87 mg/g. Histopathologic examination of random biopsies obtained from the duodenum revealed markedly dilated lymphatics compatible with IL. Constrictive pericarditis was diagnosed by tagged cine cardiac magnetic resonance imaging.
Results:
Pericardiectomy was performed for the patient. Genetic analysis was done and heterozygous mutation E148Q was detected as a disease-causing Mediterranean fever (MEFV) mutation. Colchicine was started after the operation. Six months after the initiation of regular colchicine therapy, echocardiography revealed disappearance of CP.
Conclusion:
This is the first reported case of PLE with a distended right jugular vein due to CP secondary to familial Mediterranean fever associated with E148Q heterozygosity in the MEFV gene.
Insights
This case study highlights a rare instance of protein-losing enteropathy (PLE) caused by constrictive pericarditis (CP) in an 8-year-old boy. Treatment with colchicine successfully resolved the CP and associated PLE.
Area of Science:
- Cardiology
- Gastroenterology
- Genetics
Background:
- Constrictive pericarditis (CP) is an uncommon cause of protein-losing enteropathy (PLE) stemming from intestinal lymphangiectasia (IL).
- This report details a unique case of IL and PLE secondary to CP in an 8-year-old Turkish male.
Observation:
- The patient presented with bilateral pretibial edema and eyelid swelling due to hypoproteinemia, alongside a distended right jugular vein.
- Laboratory results confirmed PLE with elevated fecal alpha-1 antitrypsin.
- Duodenal biopsies showed dilated lymphatics consistent with IL, and cardiac MRI diagnosed constrictive pericarditis.
Findings:
- Surgical pericardiectomy was performed, followed by genetic analysis revealing a heterozygous E148Q mutation in the Mediterranean fever (MEFV) gene.
- The patient was initiated on colchicine therapy post-operation.
- Six months of colchicine treatment led to the resolution of constrictive pericarditis, as confirmed by echocardiography.
Implications:
- This case represents the first documented instance of PLE with a distended jugular vein due to CP secondary to familial Mediterranean fever (FMF).
- The findings underscore the importance of considering CP in pediatric patients with unexplained PLE and IL.
- Successful treatment with colchicine suggests a potential therapeutic role for this medication in similar FMF-associated CP cases.
