Giardia lamblia infection was documented by jejunal biopsy in a previously healthy 2-year-old boy with acute onset of hypoproteinemia due to protein-losing enteropathy. All symptoms and abnormal laboratory findings resolved with anti-Giardia therapy. This is only the second case report of giardiasis with documented protein-losing enteropathy. Further application of the fecal alpha 1-antitrypsin assay may help to clarify the relationship between Giardia infection and protein-losing enteropathy and its role in development of malnutrition.

A 32-year-old man with an 18-year history of protein losing enteropathy (PLE) was admitted to hospital for abdominal distention. On physical examination, he had massive pleural effusion, ascites and edema of the right leg, but no superficial lymphadenopathy or organomegaly. Laboratory studies revealed mild microcytic anemia and hypoproteinemia. alpha 1-antitrypsin clearance was elevated (316 ml/day). Examination of ascites disclosed numerous lymphoblastoid cells of B cell phenotype with mu chain and lambda light chain of immunoglobulin (Ig) in the cytoplasm. Southern blot analysis showed monoclonal rearrangement of mu chain and lambda chain genes. No evidence of lymphomatous involvement of lymph nodes and non-lymphoid organs was found by CT scan, ultrasound echography and gallium scan of the chest and abdomen. Bone marrow biopsy was negative. Thus, a diagnosis of non-Hodgkin lymphoma (NHL) stage IVB limited in the pleural and peritoneal cavities was made. He was treated with the combination chemotherapy of BACOD with high dose ara-C or methotrexate followed by 4 doses of autologous LAK cell infusion resulting in no significant response. The massive pleural effusion, ascites and edema of the leg have not been improved. We consider this to be a rare case of NHL associated with PLE which is extremely resistant to chemotherapy or LAK therapy.

Severe hypoproteinemia often accompanies the development of graft-versus-host disease of the intestine in allogeneic bone marrow transplant patients. To determine whether or not protein loss occurs across the intestinal mucosa in this severe diarrheal illness, we measured fecal alpha 1-antitrypsin once per week in 24-h stool specimens from 25 consecutive patients during hospitalization for bone marrow transplantation. The mean alpha 1-antitrypsin concentration and serum clearance for these patients before transplantation were below 2.6 mg/g stool and 13.0 ml/day (upper limits for normals). Values for all patients increased moderately after pretransplant conditioning. Values for patients who did not develop graft-versus-host disease of the intestine returned to baseline levels; however, those for patients with graft-versus-host disease of the intestine became markedly and persistently elevated (concentration ranged from 16.6 to 51.1 mg/g, clearance from 66.6 to 384.5 ml/day). We conclude that mucosal protein exudation contributes to the hypoproteinemia of graft-versus-host disease of the intestine and that measurement of fecal alpha 1-antitrypsin can be used as a marker for this disease.

A 44-year-old man with neurofibromatosis suffered from severe diarrhea and progressive hypoproteinemia. Enteric protein loss was confirmed by an alpha 1-antitrypsin clearance test. An x-ray study showed irregular mucosa in the distal segment of the ileum. Protein loss has subsided after ileocecal resection. Laparotomy and radiological examinations failed to demonstrate neurofibroma or other tumors in the abdomen. The resected ileum revealed marked edema of the wall and a pseudomembranous enteritis-like appearance in the luminal surface. Microscopically, lymphatic vessels in the intestinal wall were dilated. Marked thickening of the intima with spindle cell proliferation was observed in the mesenteric arteries and veins. This finding is consistent with vascular changes in neurofibromatosis. These vascular changes in the mesentery due to neurofibromatosis may cause protein-losing enteropathy by altering the hemodynamic state and microvascular permeability in the intestine.
