An experimental protein-calorie malnutrition was produced in weanling Sprague-Dawley rats. The model resembles human malnutrition with respect to weight loss, inanition, angular stomatitis, anemia, lymphopenia, hypoproteinemia with hypoalbuminemia, and marked thymic involution. In addition, systemic invasion by gram-negative rods was documented. However, no edema was produced, and animals did not survive for longer than six weeks on the protein-deficient diet. One percent glycogen was found to be a satisfactory nonprotein stimulus for induction of a peritoneal exudate consisting primarily of young macrophages. Electron microscopy showed that morphologic events of phagocytosis and degranulation proceeded normally in macrophages from protein-deficient animals. In addition, cell surface receptors for IgG were preserved under these experimental conditions. These data indicate that weanling rats may be employed as a small animal model for servere, fulminant protein-calorie malnutrition in humans.

The authors report two cases of exsudative enteropathy characterised by the existence of oedema of the lower limbs associated with hypoproteinemia and marked lymphopenia with disturbances of the P.V.P. test. In both cases lymphography demonstrated major abnormalities with obvious obstruction in one case, and signs of slowing of lymph flow with appearances of dysplasia in the other. Surgery permitted us in one case, to discover a calcified lymph node probably due to tuberculosis. The etiology of these cases is discussed and seems to be mainly related to abnormalities of the lymphatic system. A low fat diet and administration of medium-chain triglycerides, gave an undoubted improvement when the treatment was followed by the patient. These two cases illustrate well the difficult diagnostic and therapeutic problems sometimes raised by syndromes of exsudative enteropathy, in particular owing to the many possible causes.

Intestinal lymphangiectasia (IL) may vary widely in its manifestations and severity. Fifteen children seen between 1960 and 1974 with histologically proven IL are analyzed by clinical, laboratory, radiologic, and histologic criteria. Remissions occurred in most patients and none died. Exacerbations occurred in five children. Diarrhea was present in 14 patients and in 13 appeared before the age of 3 years. Vomiting occurred in nine patients and growth retardation in seven. Four children had associated peripheral lymphedema and two of these had a family history of lymphedema, both had affected fathers and one had affected siblings and paternal cousins. Seven had hypoproteinemic edema, and of these, four suffered from hypocalcemic seizures. Chylous effusions were present in five. Hypoproteinemia was present in 12 although five had no hypoalbuminemic edema. Six had lymphopenia which was related to the severity of the disease and was the last abnormality to disappear after clinical remission. Lymphopenia may first appear years after the protein loss begins. Upper gastrointestinal tract series were performed in 13 children and had diagnostic supportive value in seven. Six children had two or more small-intestinal biopsies done. They all showed great variation from one examination to the other, ranging from a normal appearance to severe changes. Lymphatic block may occur at different sites-in the lamina propria only, generalized (lamina propria, submucosa, serosa, and mesentery), or conversely in the mesentery alone with minimal changes in the lamina propria. In three patients intravenous hyperalimentation was necessary. Specific treatment with a high-protein, low-fat diet with added medium-chain triglyceride (MCT) is valuable. Surgical resection was of benefit in one patient, and anastomosis of mesenteric to para-aortic lymph nodes in another.

Lymphocytic-plasmacytic enteritis (LPE) was diagnosed by intestinal biopsy in 24 dogs with chronic small intestinal diarrhea. Vomiting, weight loss, and reduced appetite were frequent. Breed predispositions were not documented, although four patients were German Shepherd dogs. Hypoproteinemia, hypoalbuminemia, and hypoglobulinemia were common and most likely a result of protein-losing enteropathy. Other biochemical abnormalities were uncommon. Intestinal malabsorption was common. Neutrophilia (sometimes with increased band neutrophils), monocytosis, lymphopenia, and eosinopenia were the most consistent hematologic abnormalities. The severity of the lymphocytic-plasmacytic infiltration was not significantly different (P greater than 0.05) between regions of small intestine. However, the severity of cellular infiltration often varied among different regions of small intestine in the same dog. Changes in villous architecture and lacteal dilation were common. Intestinal nematode infestation was diagnosed in five dogs, and pancreatic exocrine insufficiency was diagnosed in one dog. In the remaining 18 dogs, besides LPE, no other associated or concurrent intestinal disease was diagnosed.

The main reason for the virtual abandonment of external thoracic duct drainage as an immunosuppressive measure is not its lack of efficacy, but the time-consuming technical problems of maintaining cannula patency and replacing the large obligatory losses of fluid and protein. In an effort to overcome these problems we have devised a method of diverting thoracic duct lymph internally into the esophagus of the sheep, our hypothesis being that fluid and protein should be resorbed, but lymphocytes and antibodies destroyed. By isolating that part of the venous system into which the thoracic duct drains and anastomosing this conduit to the cervical esophagus a chyloesophageal fistula was created. A mean patency of 19 days was demonstrated radiologically and there was a reproducible peripheral blood lymphopenia of over 50% of preoperative values at 4 weeks. Although plasma albumin levels fell from 37 g/L to 29 g/L at 1 week, they remained stable thereafter. No parenteral fluid or protein was administered, yet the animals remained well with no significant weight loss or overt signs of dehydration or hypoproteinemia. Skin allograft mean survival time was prolonged from 9 to 11.8 days (P less than 0.01).

Aplasia cutis congenita (ACC) is a rare skin defect usually localized to the vertex. It has been reported in association with other disorders involving mainly ectodermal and mesodermal structures. We discovered the association of ACC and intestinal lymphangiectasia (IL) in a patient and probably in his brother. At birth, the propositus had ACC of the vertex and edema, which persisted for six months. At 3 years of age he presented with generalized edema and was found to have hypoproteinemia and lymphopenia. Radioisotope studies and a small-intestinal biopsy confirmed the diagnosis of IL. On a fat-free, medium-chain triglyceride-containing diet, clinical and laboratory findings returned to normal. A sibling born one year after his brother's presentation had nonpitting limb edema and extensive ACC of the vertex with an underlying bony defect. He died in shock at 2 months of age, after sudden profuse bleeding from the sagittal sinus. The association between ACC and IL is another example of combined anomalies with both ectodermal and mesodermal involvement that is most probably not coincidental.

A syndrome of acquired immunodeficiency has been identified in a group of rhesus monkeys (Macaca mulatta) which died at the California Primate Research Center. Clinical evaluation of these animals revealed that 50% or more had lymphadenopathy, weight loss, and diarrhea. At least 30% had splenomegaly, fever, cutaneous abscesses and/or arthritis/myositis. Two animals had fibrosarcomas. Anemia was seen in 19 animals, lymphopenia in 14, granulocytopenia in four and thrombocytopenia in three. Hepatitis was diagnosed histopathologically in 13. Electrophoresis revealed hypoproteinemia, hypoalbuminemia and hypogammaglobulinemia. Numerous bacterial, protozoal, and viral agents were identified including cytomegalovirus and leukocyte-associated herpesvirus. Pathologic lesions included severe post-reactive depletion of lymphocytes in germinal centers and paracortical regions of lymph nodes. Clinical and pathologic changes indicate an acquired immunodeficiency syndrome which has some similarities to AIDS in humans. This disease in monkeys may provide a model for studying that disease.

A 10-year-old Tennessee Walker gelding, with a history of progressive weight loss, intermittent colic and lethargy, had a slight fever, tachycardia, tachypnea, pallor, ascites and marked ventral edema. Blood analyses revealed anemia, leukocytosis, neutrophilia with a left shift, lymphopenia, monocytosis, hypoproteinemia and a slightly increased SDH level. Abdominocentesis produced red-orange fluid with many RBC and an increased fibrinogen content. Rectal palpation revealed a large mass in the left caudal abdominal quadrant. The animal died shortly after resection of the mass. The histopathologic diagnosis was lymphosarcoma, involving the spleen, liver and lung.

Two 6-month-old male infants with diarrhea, malabsorption, and hypoproteinemia, who were initially diagnosed as having combined immunodeficiency syndrome, recovered with intensive plasma therapy. Prior to the onset of diarrhea, they had normal serum protein and lymphocyte values. Immunologic features of combined immunodeficiency included lymphopenia, diminished B and T cells, cutaneous anergy, low immunoglobulin levels, and poor lymphocyte proliferative responses in vitro. Prior to therapy, both children had rectal ulcerations by proctosigmoidoscopy, colitis by rectal biopsy, and moderate to severe intestinal villus abnormalities by small bowel biopsy; plasma cells were absent Both had generalized malabsorption of all nutrients. Both infants were given irradiated fresh-frozen plasma for one to two months at 11 to 20 ml/kg/day to replace intestinal protein losses. During this time, diarrhea slowed, biopsy morphology improved, and immunoglobulin levels and T-cell function became normal. After discontinuance of plasma therapy, normal immune function and a normal stool pattern with reversal of malabsorption continued. Since intensive plasma therapy may have contributed to the reversal of the immunodeficiency state, a trial of such therapy is recommended in similar patients.

The authors report a case of sarcoidosis associated with protein losing enteropathy. The diagnosis of intrathoracic stage I sarcoidosis was based on x-ray and biopsy of mediastinal lymph nodes. Enteric protein loss was suspected because of edema lasting for 2 yr, hypoproteinemia, decreased concentrations of serum immunoglobulins, and lymphopenia involving mainly T-cells and proved by 51CrCl3 test (21%/120 hr). Lymphography was consistent with granulomatous involvement of retroperitoneal lymph glands while small bowel biopsy showed blunt villi and dilated lacteals. All the pathological parameters normalized after 6 mo of prednisone treatment. In some cases of sarcoidosis, when abdominal lymph glands are involved, cellular and humoral immunologic derangements may be caused or potentiated by excessive enteric protein and lymphocyte loss.
