Intestinal lymphangiectasia with protein losing enteropathy, toxic copper accumulation and hypoparathyroidism. • Aust N Z J Med. 1990 Apr;20(2):167-9
A 13-year-old girl presented with malabsorption which was ascribed to intestinal lymphangiectasia. • Three years later a generalised seizure resulted from hypocalcaemia that was shown to be due to hypoparathyroidism during investigation of which toxic copper accumulation was recognised. • The chance occurrence of three rare conditions is extremely remote making intestinal lymphangiectasia likely as the primary pathology.
It is suggested that chronic intestinal loss of the copper-carrying caeruloplasmin resulted in toxic parathyroid deposition of copper leading to hypoparathyroidism with consequent hypocalcaemic seizure.
Protein-losing gastroenteropathy • Protein-losing gastroenteropathies are characterized by an excessive loss of serum proteins into the gastrointestinal tract, resulting in : • hypoproteinemia (detected as hypoalbuminemia), • edema, • and, in some cases, pleural and pericardial effusions.
Diagnosis • The diagnosis of protein-losing gastroenteropathy should be considered in patients with hypoproteinemia in whom other causes, such as malnutrition, heavy proteinuria, and impaired protein synthesis due to liver diseases have been excluded.
PATHOGENESIS • Once plasma proteins pass into the gastrointestinal tract, they are degraded rapidly to amino acids and reabsorbed into the portal circulation. • Other serum components (eg, iron, lipids, trace elements) also may be lost in the gut.
The increase in intestinal leakage of plasma proteins can occur via one of two mechanisms: • Mucosal injury with or without erosions/ulcerations as in inflammatory bowel disease (IBD) and celiac disease. • Increased Iymphatic pressure in the gut due to granulomatous and neoplastic involvement of the Iymphatic system or after dilated lymph vessels leak protein via the surface epithelium into the gut.
The latter mechanism can occur in : • intestinal lymphangiectasia, • congenital abnormalities of the lymphatic system, • or disorders of venous stasis such as congestive heart failure or constrictive pericarditis.
