Intestinal Lymphangiectasia associated with Hemihypertrophy: Primary intestinal lymphangiectasia is a disease characterized by dilated intestinal lymph vessels which manifests as a protein losing enteropathy. We present a patient with chronic diarrhea, recurrent rectal prolapse and left upper limb hemihypertrophy associated with lymphopenia and hypoalbuminemia.

Primary intestinal lymphangiectasia was diagnosed with upper endoscopy and biopsy.

Intestinal Lymphangiectasia associated with Hemihypertrophy: A case report

Nutritional treatment was successfully begun. Primary intestinal lymphangiectasia is a rare disease characterized by dilation of the lymph nodes of the mucosa, submucosa, serosa and mesentery bowel. This leads to secondary lymphatic leakage which is responsible for the clinical condition. A wide spectrum of clinical and paraclinical manifestations can be present in patients with this diseases.

The exact manifestations which present themselves are conditioned by the anatomical location and extent of the lymphatic anomaly 1. Here we report the case of a child with intestinal lymphangiectasia associated with hemihypertrophy of his upper left limb. A 33 month old male patient was admitted after 9 months of recurrent rectal prolapse associated with liquid stools. Stools were not fetid and they contained no mucus or blood.

Patient’s frequency of defecation was five to six times per day sometimes accompanied by non-bilious vomiting. No blood was found in patient’s vomit. Patient had no history of fever or other digestive or extra-digestive symptoms. Patient had been hospitalized previously for self-limiting edema with ascites, hypoalbuminemia, lymphopenia and elevation levels of transaminase which subsequently resolved.

There were no other issues relevant to the current illness in the patient’s personal or family history See Figures 1 and 2. Upon admission the patient was found to have abdominal distension, rectal prolapse and left upper limb hemihypertrophy that compromised the forearm and hand. An assessment of the patient’s nutritional status was compatible with short stature. There were no other significant findings from the physical examination.

Paraclinical evidence showed hypochromic microcytic anemia, lymphopenia and hypoalbuminemia see Table 1. Diagnostic tests performed included a series of tests of fecal matter to rule out parasites. The serum ionogram, liver function tests, and kidney function tests were normal.

The diagnosis was confirmed by intestinal biopsy See Figures 34567 and 8. Because little changed in response to this treatment, it was decided to change diet to a formula consisting exclusively of medium chain triglycerides. After 15 days paraclinical and clinical indications showed a positive response characterized by neonatxl reduction in the number of stools to only one or two per day.

Stools also became well formed. Patient gained approximately 30 grams of weight every day. InWaldmann et al. These patients had hypoproteinemia and edema associated with low serum albumin and immunoglobulin levels.

Daily excretion of fecal protein was twice as high as that of healthy patients. Microscopic examination of biopsies from the small intestine showed varying degrees of dilation of lymphatic vessels in the mucosa and submucosa.

These authors proposed the term intestinal lymphangiectasia 2. Intestinal lymphangiectasia is responsible for lymphatic leakage into the intestinal lumen leading to hypoalbuminemia and lymphopenia. This edema is caused by decreased oncotic pressure associated with hypoproteinemia. This condition can present through a broad spectrum of clinical and paraclinical manifestations which are conditioned on the anatomical location and extent of the lymphatic anomaly 1.

The intestinal lesion can be patchy or can be located at a more or less specific site nsonatal. There may be involvement of other structures such as the uterus, lungs and quillsa. Many diseases are associated with excessive loss enteric proteins from the plasma. They include intestinal lymphangiectasia, Menetrier’s disease and inflammatory conditions such as lupus erythematosus 4. Primary intestinal lymphangiectasia is typically limited to the small intestine although its etiology and prevalence are unknown.

Children with primary intestinal lymphangiectasia are usually diagnosed before the age of 3. Secondary intestinal lymphangiectasia occurs most frequently in adults and is an effect secondary to increased lymphatic pressure.

Diagnosis and management of congenital neonatal chylous ascites

Among its causes are bowel lymphoma, lymphoenteric fistulas, Whipple’s disease, Crohn’s disease, sarcoidosis, tuberculosis, intestinal giardiasis, radiotherapy, chemotherapy, Fontan surgery and constrictive pericarditis. Many diseases including intestinal lymphangiectasia, Menetrier’s disease and inflammatory conditions such as lupus erythematosus are associated with excessive enteric loss of plasma ascits 4.

It is usually peripheral and symmetric with pitting and varies from moderate to severe. It is common to have pleural effusion, pericarditis and chylous ascites. It may be suspected in utero because of fetal ascites or lower limb edema 4. Patients may exhibit fatigue, abdominal pain, nausea, vomiting and failure to thrive. The main digestive symptom is moderate and intermittent diarrhea.

Mechanical ileus may also be present secondary asciitis areas of edema in the small bowel leading to thickening of the intestinal wall and reduction of the lumen. The deficit can cause malabsorption of fat soluble vitamins. According to some descriptions, hypocalcemia can lead to secondary tetany and seizures.

There are reports that associate it with osteomalacia, osteoporosis, development of vitamin D deficiency and secondary hyperparathyroidism 5. Patients may have iron deficiency with anemia secondary to chronic bleeding for multiple nonspecific ulcers in the small bowel. In addition there have been reports of gastrointestinal bleeding without significant paraclinical evidence of enteric protein loss.

This has been associated with increased lymphatic pressure in lympho-venous anastomoses with venous vessel ruptures and secondary bleeding. Biological abnormalities which are indirectly suggestive of intestinal lymphangiectasia include hypoproteinemia, hypoalbuminemia, hypogammaglobulinemia with low levels of IgG, IgM and IgA, low counts of CD4 and T cells, and lymphopenia.

Although these patients have severe hypogammaglobulinemia and lymphopenia, the risk of infection is not very high and opportunistic infections are rare 6. There have been reports of meningitis and disseminated cryptococcal infections. One case of severe infection by hemolytic group b streptococcus and one case of gelatinous transformation of the bone marrow have been described. Another report discussed replacement of hematopoietic cells and adipocytes by an amorphous extracellular material composed of jeonatal which was attributed to malnutrition resulting from malabsorption 4.

The following criteria have been described for diagnosis: Ascitiis first three items are suggestive, but the next two are essential for establishing the diagnosis 7. Evidenced of macroscopic abnormalities in upper endoscopy are clear.

They include yellowish cream color villi within the intestinal mucosa corresponding to lymphatic vessel dilation. In mild presentation the mucosa may appear to have edema asciits being creamy.

Endoscopy can be negative when lesions are segmented or localized. In these cases the endoscopic video capsule is useful for detecting the presence, location and extent of intestinal lymphangiectasia. One type has a diameter less than 1 mm while the other’s diameter exceeded 3 mm 8.

Histological examination of biopsies from the duodenum, jejunum and ileum confirm the presence of white material with dilated lymphatic vessels located in the mucosa, submucosa and serous in the absence of inflammation. The nodes may be enlarged in many or a few villi and dilated villi can also be found in the intestinal mesentery.

When the 24 hour alpha-1 antitrypsin clearance test shows elevated levels of alpha-1 antitrypsin it may be due to enteric protein loss. The method of the alpha-1 antitrypsin clearance test has replaced scintigraphy which is more expensive and less often available and because of the use of a human product carries risks of infection.

When albumin scintigraphy finds the elevated levels of human serum albumin bound to technetium it can indicate intestinal protein loss in this region.

Serial examinations are required within 24 hours since the loss of protein in the intestine is intermittent.

This test is very sensitive and is able to identify the site of protein loss. Abdominal ultrasound can demonstrate characteristics such as severe mesenteric edema, ascites, dilated bowel loops, diffuse thickening of the walls, and hypertrophy of the folds which are suggestive of primary intestinal lymphangiectasia. When a CT scan with contrast shows diffuse and nodular thickening of the walls of the small intestine, edema as a result of dilated lymph nodes within the villi, and some degree of intestinal dilatation, it suggests intestinal lymphangiectasia.

These findings are similar in adults and children. There is also the halo sign which is a low attenuation inner ring surrounded by an outer ring of increased attenuation which has been reported in intestinal lymphangiectasia, Crohn’s disease, ulcerative colitis and radiation enteritis.

Computed tomography with contrast may be useful for the detection of localized areas of lymphangiectasia. An MRI with contrast can show ascites, mesenteric edema with hyperintense fluid collection around the mesenteric blood vessels, and a ring surrounding areas of markedly hyperintense thickened bowel loops. A lymphatic scan can be useful for identification of abnormalities of the node tree and for confirmation of lymphedema. We have used different treatments including dietary modifications, octreotide, antiplasmin therapy, corticosteroids, surgical resection of the affected segments and treatments of symptoms such as the infusion of albumin and paracentesis.

We have also used peritoneal venous shunts and intestinal transplantation 5. The cornerstone of treatment for primary intestinal lymphangiectasia is a reduction of long chain fatty acids derived from food combined with the addition of medium chain triglycerides 9. Dietary modifications aim at controlling symptoms and the consequences of lymphatic obstruction but do not alter the underlying disease process.

Exclusion of long chain fatty acids prevents the swelling and rupture of malformed nodes while medium chain triglycerides are directly absorbed into portal venous circulation. Evidence of improvement in clinical and laboratory parameters in these patients such as changes in levels of albumin, immunoglobulins and lymphocyte counts should be seen within weeks.

Refractory edema associated with hypoproteinemia has been described in some cases For cases that do not respond or in which the clinical indications are severe total, parenteral nutrition may be required Octreotide is an analogue of somatostatin that can help reduce losses of lymph nodes through several mechanisms.

It has been reported to be useful in two cases which were refractory to other treatments. A study of 11 pediatric patients diagnosed with primary intestinal lymphangiectasia who were treated with doses of mg of subcutaneous octreotide twice a day for 3 to 37 months found decreases in the total number of stools and the requirements of albumin but only one patient revealed histopathological improvement.

Acute pancreatitis was observed as an adverse effect in one case There are also case reports of patients who did not respond adequately to octreotide or dietary treatment but who responded well to antiplasmin uqilosa consisting of 1 gram of tranexamic acid administered orally 3 times daily 3.

This treatment is based on increasing the activity of fibrinolytic plasma or tissue in these patients 9. However, the responses described with this treatment varied and improvements were partial.
