1/48. Abdominal lymphatic dysplasia and 22q11 microdeletion.We report the case of a child with 22q11 microdeletion who presented with abdominal lymphatic dysplasia resulting in exsudative enteropathy. This primitive and localized lymphatic malformation is consistent with the vascular theory in the velocardiofacial syndrome.- - - - - - - - - - ranking = 1keywords = enteropathy (Clic here for more details about this article) |

Stable reversal of pathologic signs of primitive intestinal lymphangiectasia with a hypolipidic, MCT-enriched diet.We report on a patient with protein-losing enteropathy due to primitive intestinal lymphangiectasia with an early reversal of clinical and biochemical signs and a stable late reversal of pathologic signs after treatment with a hypolipidic diet enriched with medium-chain triacylglycerols.- - - - - - - - - - ranking = 1keywords = enteropathy (Clic here for more details about this article) |
3/48. Very late onset small intestinal B cell lymphoma associated with primary intestinal lymphangiectasia and diffuse cutaneous warts.As only a handful of lymphoma cases have been reported in conjunction with primary intestinal lymphangiectasia, it is not yet clear if this association is merely fortuitous or related to primary intestinal lymphangiectasia induced immune deficiency. We report on two female patients, 50 and 58 years old, who developed small intestinal high grade B cell lymphoma a long time (45 and 40 years, respectively) after the initial clinical manifestations of primary intestinal lymphangiectasia. They presented with a longstanding history of fluctuating protein losing enteropathy, multiple cutaneous plane warts, and markedly dilated mucosal and submucosal lymphatic channels in duodenal biopsies. One had a large ulcerated tumour of the proximal ileum and the other diffuse ileal infiltration. In both, histological examination showed centroblastic high grade B cell lymphoma associated with duodenojejuno-ileal mucosal and submucosal lymphangiectasia. They were subsequently successfully treated with surgery and postoperative chemotherapy (AVmCP: adriamycin, cyclophosphamide, Vm26, and prednisolone), and chemotherapy alone (PACOB: adriamycin, cyclophosphamide, vincristine, bleomycine, and prednisolone), respectively. A three year follow up in both cases showed persistent diffuse lymphangiectasia without evidence of lymphoma. The present findings support the hypothesis that primary intestinal lymphangiectasia is associated with lymphoma development.- - - - - - - - - - ranking = 1keywords = enteropathy (Clic here for more details about this article) |
4/48. Computed tomography after lymphangiography in the diagnosis of intestinal lymphangiectasia with protein-losing enteropathy in Noonan's syndrome.Noonan's syndrome is a rare congenital disorder that may be associated with abnormalities in the lymphatic drainage. In this case of a 21-year-old man CT after bipedal lymphangiography confirmed the diagnosis of intestinal lymphangiectasy causing protein-losing enteropathy in Noonan's syndrome by showing contrast-enhanced abnormal lymphatic vessels in the mesentery and the intestinal wall. Because of the benefit of diet in case of intestinal involvement, we recommend a thorough documentation of the lymphatic drainage with lymphangiography followed by CT, if clinical signs of lymphatic dysplasia, such as pleural effusions, lymphedema, or hypoproteinemia are present.- - - - - - - - - - ranking = 5keywords = enteropathy (Clic here for more details about this article) |
5/48. A case of protein-losing enteropathy caused by intestinal lymphangiectasia in a preterm infant.Intestinal lymphangiectasia is characterized by obstruction of lymph drainage from the small intestine and lacteal dilation that distorts the villus architecture. Lymphatic vessel obstruction and elevated intestinal lymphatic pressure in turn cause lymphatic leakage into the intestinal lumen, thus resulting in malabsorption and protein-losing enteropathy. Intestinal lymphangiectasia can be congenital or secondary to a disease that blocks intestinal lymph drainage. We describe the first case of intestinal lymphangiectasia in a premature infant. The infant presented with peripheral edema and low serum albumin; high fecal concentration of alpha(1)-antitrypsin documented intestinal protein loss. endoscopy showed white opaque spots on the duodenal mucosa, which indicates dilated lacteal vessels. histology confirmed dilated lacteals and also showed villus blunting. A formula containing a high concentration of medium chain triglycerides resulted in a rapid clinical improvement and normalization of biochemical variables. These features should alert neonatologists to the possibility of intestinal lymphangiectasia in newborns with hypoalbuminemia and peripheral edema. The intestinal tract should be examined for enteric protein losses if other causes (ie, malnutrition and protein loss from other sites) are excluded. The diagnosis rests on jejunal biopsy demonstrating dilated lymphatic lacteal vessels.- - - - - - - - - - ranking = 5keywords = enteropathy (Clic here for more details about this article) |
6/48. Primary intestinal lymphangiectasia successfully treated with octreotide.A 21-year-old man with diarrhea and edema was admitted to our hospital and diagnosed with protein-losing enteropathy caused by primary intestinal lymphangiectasia. He was placed, in turn, on a low-fat diet, an elemental diet, and, subsequently, fasting therapy with total parenteral nutrition (TPN) support. However, his symptoms were not relieved, but, rather were exacerbated. On the 45th day of hospitalization, octreotide therapy was initiated. After 2 weeks of treatment, his clinical symptoms, as well as hypoproteinemia and hypoalbuminemia, gradually became alleviated. The improvement was confirmed in terms of scintigraphy, endoscopy, and histology of the duodenum. The patient remained healthy until 6 months after the commencement of octreotide treatment, when he discontinued octreotide at his own discretion, at which point the symptoms recurred. Resumption of the drug, however, again brought about remission, which has continued until the present, March 2000. Thus, octreotide therapy is one modality which may be useful for refractory primary intestinal lymphangiectasia.- - - - - - - - - - ranking = 1keywords = enteropathy (Clic here for more details about this article) |
7/48. Lymphangiectasia with persistent Mullerian derivatives: confirmation of autosomal recessive Urioste syndrome.We report on a sibship with protein-losing enteropathy related to intestinal lymphangiectasia, a peculiar face, and genital anomalies. The parents are distantly related and from Dutch ancestry. The first patient was born with a protein-losing enteropathy, craniofacial anomalies, and renal defects. At 1 year of age, she died of severe complications of the protein-losing enteropathy and respiratory distress. Her brother was a cytogenetically normal male fetus identified by prenatal ultrasound at 19 weeks with similar anomalies. The pregnancy was terminated at 20 weeks. autopsy showed mullerian duct remnants. These cases seem to confirm the Urioste syndrome [Urioste et al., 1993: Am J Med Genet 47:494-503]. Although it was previously only reported in 46,XY individuals, this report of a consanguineous family with an affected sibship of both sexes suggests it to be an autosomal recessive entity.- - - - - - - - - - ranking = 3keywords = enteropathy (Clic here for more details about this article) |
8/48. Primary intestinal and thoracic lymphangiectasia: a response to antiplasmin therapy.Lymphangiectasia is a congenital or acquired disorder characterized by abnormal, dilated lymphatics with a variable age of presentation. We describe a case of lymphangiectasia with intestinal and pulmonary involvement in an adolescent female, who presented with many of the classic features including chylous pleural effusions, lymphopenia, hypogammaglobinemia, and a protein-losing enteropathy. She also presented with recurrent lower gastrointestinal bleeding, which is infrequently described. The patient did not improve with bowel rest and a low-fat medium-chain triglyceride diet and had little improvement with octreotide acetate therapy. However, she had a clinical response to antiplasmin therapy, trans-4-aminothylcyclohexamine carboxylic acid (tranexamic acid) in terms of serum albumin and gastrointestinal bleeding. She continues to have exacerbations of her condition, as well as persistent lymphopenia and chronic pleural effusions.- - - - - - - - - - ranking = 1keywords = enteropathy (Clic here for more details about this article) |
9/48. Successful resection of localized intestinal lymphangiectasia post-Fontan: role of (99m)technetium-dextran scintigraphy.Intestinal lymphangiectasia is a well-recognized complication of the fontan procedure, occurring in up to 24% of patients. Because of the loss of chylous fluid into the gut lumen, protein-losing enteropathy results as well as lymphopenia and hypogammaglobulinaemia. In some cases, dilated lymphatics in the intestinal serosa or mesentery also rupture, causing chylous ascites. Standard medical and cardiac surgical interventions are generally ineffective and the condition is frequently lethal. We report a case of intractable and life-threatening chylous ascites and chylothorax in a 14-year-old girl, associated with intestinal lymphangiectasia and protein-losing enteropathy after a fontan procedure for tricuspid atresia. The condition was refractory to all standard medical therapies, including dietary modifications, diuretics, corticosteroid therapy, albumin infusions, octreotide, heparin, bowel rest, and parenteral nutrition. Cardiac surgery to optimize her hemodynamic status was also ineffective and large volume pleural and ascitic fluid losses continued. Having exhausted all other therapeutic modalities, (99m)technetium-dextran scintigraphy was performed to assess the extent of intestinal protein loss and the potential for surgical intervention. Scintigraphy suggested localized protein loss from the proximal jejunum and subsequent segmental resection was effective. Postoperatively, ascites and pleural effusions resolved, and there was no evidence of short bowel syndrome. growth has accelerated and the patient has entered puberty. There is mild persistent intestinal protein loss requiring diuretic therapy. Ascites or pleural effusions are absent, and the patient remains well >2 years after surgery. Intestinal lymphangiectasia post-Fontan procedures has traditionally been ascribed to hemodynamic factors such as raised systemic venous pressure, which would predispose to a generalized intestinal lesion. However, in this case, scintigraphy demonstrated a localized, surgically correctible lesion. To our knowledge, this is the first reported case of the use of (99m)technetium-dextran scintigraphy for this indication and of successful partial small bowel resection in such a case.- - - - - - - - - - ranking = 2keywords = enteropathy (Clic here for more details about this article) |
10/48. Successful treatment of protein-losing enteropathy induced by intestinal lymphangiectasia in a liver cirrhosis patient with octreotide: a case report.A 47-yr-old man with hepatitis b virus associated liver cirrhosis was admitted to our hospital with diarrhea and generalized edema and diagnosed as protein-losing enteropathy due to intestinal lymphangiectasia by intestinal biopsy and 99m Tc albumin scan. During hospitalization, he received subcutaneous octreotide therapy. After 2 weeks of octreotide therapy, follow-up albumin scan showed no albumin leakage, and the serum albumin level was sustained. We speculate that liver cirrhosis can be a cause of intestinal lymphangiectasia and administration of octreotide should be considered for patients with intestinal lymphangiectasia whose clinical and bio-chemical abnormalities do not respond to a low-fat diet.- - - - - - - - - - ranking = 5keywords = enteropathy (Clic here for more details about this article) |
