Intestinal Lymphangiectasia: Insights on Management and Literature Review

Abstract

Patient: Male, 24 Final Diagnosis: Intestinal lymphangiectasia Symptoms: Frequent episodes of diarrhea • recurrent infections • swelling in the lower limbs Medication: Octreotide • MCT oils Clinical Procedure: Endoscopic exam • Doppler ultrasound study • abdominal CT scan Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Intestinal lymphangiectasia (IL) is a rare disease characterized by a dilatation of the intestinal lymphatics and loss of lymph fluid into the gastrointestinal tract leading to hypoproteinemia, edema, lymphocytopenia, hypogammaglobinemia, and immunological abnormalities. Iron, calcium, and other serum components (e.g., lipids, fat soluble vitamins) may also be depleted. A literature search revealed more than 200 reported cases of IL. Herein, we report our observations of a patient diagnosed with IL; we also present our conclusion for our review of the published literature. Case Report: A 24-year-old male was admitted to Aleppo University Hospital with the complaints of abdominal pain, headache, arthralgia, fever, and rigors. His past medical history was remarkable for frequent episodes of diarrhea, recurrent infections, and swelling in the lower limbs. In addition, he had been hospitalized several times in non-academic hospitals due to edema in his legs, cellulitis, and recurrent infections. In the emergency department, a physical examination revealed a patient in distress. He was weak, dehydrated, pale, and had a high-grade fever. His lower extremities were edematous, swollen, and extremely tender to touch. The overlying skin was erythematous and warm. Moreover, the patient was tachycardic, tacypneic, and moderately hypotensive. The patient was resuscitated with IV fluids, and Tylenol was administered to bring the temperature down. Blood tests showed anemia and high levels of inflammatory markers. The patient’s white blood cell count was elevated with an obvious left shift. However, subsequent investigations showed that the patient had IL. Suitable diet modification plans were applied as a long-term management plan. Conclusions: IL is a rare disease of challenging nature due to its systematic effects and lack of comprehensive studies that can evaluate the effectiveness of specific treatments in a large cohort of patients. Medium-chain triglyceride (MCT) oils and diet modification strategies are effective in reducing the loss of body proteins and in maintaining near-normal blood levels of immunoglobulins. However, octreotide and MCT oils had no proven role in reducing lymphedema in our patient.
