We wished to determine whether subtotal replacement of protein in plasma removed at plasma exchange would be adequate to prevent hypovolemia and hypoproteinemia. Seven well nourished outpatients with chronic progressive multiple sclerosis underwent 60 plasma exchanges in which two liters of plasma were replaced with 750 ml saline followed by 1250 ml of a 5% albumin solution (62.5% albumin replacement). Total serum protein, protein electrophoresis, and immunoglobulin levels were measured before and after each exchange. Clinically, the exchanges were well tolerated. Total serum protein dropped by a mean of only 18% during the study and mean preexchange serum albumin levels were unchanged, even though immunoglobulins decreased by 57-72%. We conclude that in well nourished patients, partial albumin replacement of this magnitude is an adequate substitute for plasma removed in a plasma exchange.

Lipids of the blood serum were studied in 29 patients with untreated nephrotic syndrome (NS) and in 28 patients treated with corticosteroids or nonsteroid drugs. None of the patients had evidence of renal failure, either acute or chronic. The patients with untreated NS showed massive proteinuria, marked hypoproteinemia, considerable hypertriglyceridemia and hypercholesterolemia. Serum high-density lipoprotein cholesterol (HDL cholesterol) concentrations were lower in these patients than in the control group, including 35 normal subjects, and correlated with the total serum protein (r = 0.46, p less than 0.05) and serum albumin (r = 0.46, p less than 0.05). An inverse correlation was observed between HDL cholesterol and serum triglyceride levels (r = -0.58, p less than 0.01). In the treated patients the laboratory indices of NS were less pronounced. HDL cholesterol levels were within normal limits in 14 patients with NS treated mostly with nonsteroid drugs, while in the patients receiving the corticosteroids (14 subjects) they were significantly higher than in the control group.

The rat was used as an animal model to explore the mechanism responsible for the development of hepatomegaly and hypoproteinemia which commonly occur after jejunoileal bypass. Sprague-Dawley rats. 300 to 350 g, were divided into three groups of 12 animals. Six of the 12 rats per group served as study animals and six as controls. The first six were subjected to 90% jejunoileal bypass and the six controls were sham-operated and pair-fed. In the second group, six animals were subjected to 90% jejunoileal resection and six controls were sham-operated and pair-fed. Six animals in the third group were underfed so that their weights mimicked that of the bypassed animals and six controls were fed ad libitum. After 8 wk the animals were killed. Liver weights, hepatic protein content, and serum protein and triglycerides were determined. Synthesis and secretion of proteins and glycoproteins were measured using incorporation of 14C-leucine and 14C-glucosamine, respectively, into hepatic and medium proteins by liver slices. Bypassed animals demonstrated hepatomegaly, decreased serum proteins and triglycerides, and increased hepatic protein content. While both protein and glycoprotein synthesis remained normal, the secretion of these proteins into the medium appeared to be impared. Comparable changes did not occur after jejunoileal resection or after underfeeding. This study suggests that the impairment of glycoprotein and protein secretion may be a contributing factor in the increased liver weight and protein content in conjunction with decreased serum protein observed in the bypassed rat.

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.

Three indications have been considered for the clinical use of human serum albumin: nutrition, binding and transport, and the volume effect due to the oncotic properties of the protein. The use of albumin as an intravenous nutrient is clearly inappropriate. The literature on its binding and transport properties is as yet clinically inconclusive, and it seems premature to enforce product specifications based on these characteristics. The effects on blood volume and hypoproteinemia are firmly established in patients with an intact capillary system. The therapeutic implications of a capillary "permeability lesion" are a subject of current debate. Such lesions occur following extensive injuries and in patients with septic pulmonary failure. Although the data are contradictory, it is largely agreed that the serum albumin level should be kept above 30 g/litre or the total serum protein above 50 g/litre.

In 1956 we evaluated a patient who had a debilitating disease of a 2 yr duration, characterized by recurrent vomiting, diarrhea, cachexia, massive edema, hypoproteinemia, and dilated intestinal lymphatics. During our initial evaluation of this patient, we observed that 42% of her circulating protein pool was lost into her gastrointestinal tract daily, whereas normal gastrointesinal loss of protein does not exceed 1.6%. Her disease appeared to represent a classic example of intestinal lymphangiectasia. She was treated symptomatically for 13 yr with essentially no change. In 1969 the patient developed a stage IV diffuse, undifferentiated (non-Burkitt's) malignant lymphoma. Using immunoperoxidase staining, the neoplastic cells were found to contain cytoplasmic IgMKappa, suggesting that the lymphoma had a monoclonal B-cell origin. She was successfully treated with cyclophosphamide, vincristine, and prednisone. Shortly after the initiation of this systemic combination chemotherapy, her serum protein concentration returned to normal, her edema resolved, and she was cured of gastrointestinal symptoms. Moreover, repeat studies revealed that her protein loss had fallen to only 2%. The simultaneous cure of both the intestinal lymphangiectasia and lymphoma with combination chemotherapy suggests new relationships between these conditions as well as new possibilities for the treatment of acquired forms of intestinal lymphangiectasis associated with overwhelming gastrointestinal protein loss.

The present retrospective study was undertaken to determine the frequency of hypoproteinemia and hypoalbuminemia in horses with natural occurring severe liver disease. The study represents a review of case records and laboratory data of 84 horses presented with acute or chronic liver disease to the University of California Veterinary Medical Teaching Hospital between 1973 and 1991. Forty horses (48%) had serum protein concentrations above the maximum reference value (7.7 g/dL). The increase in serum protein concentration was associated with hyperglobulinemia (P = .00005, R2 = .80). Only 13% (11/84) of the horses had serum albumin concentrations below the minimum reference range (2.5 g/dL), and hypoproteinemia was found in only 1 of these horses. Of these, 18% (9/51) of the horses with chronic liver disease and 6% (2/33) of the horses with acute liver disease had albumin concentrations below the minimum reference value. Globulin concentrations in 64% of the horses (54/84) were above the maximum reference value (4.0 g/dL). The present study indicates that hypoproteinemia and hypoalbuminemia are not common features in horses with severe liver disease.

Quantitative study of serum protein loss into the alimentary tract from the tumor of gastric cancer using 111Indium-transferrin (111In-Tf) was performed. Gamma counting of 111In-Tf excreted in feces and 111In-Tf scintigram were performed in 24 patients with gastric cancer and 10 controls. Transferrin was labelled by incubating 111MBq (3mCi) of 111In chloride with approximately 13ml of patient plasma in vitro. After intravenous injection of 111In-Tf, an aliquot was weighed and its radioactivity was measured in a gamma-counter. Feces were collected every 24hrs up to 72hrs. Then 111In in the feces was calculated as a percentage of the injection dose. 111In excreted in the feces within 72hrs in patients with gastric cancer was 3.71 +/- 3.87% (mean +/- SD), which was significantly higher than the 0.48 +/- 0.26% in 10 controls. 111In in feces correlated the area of the tumor in the stomach (p < 0.001). In 18 patients positive scan was recognized and was localized the protein loss in the cavity of the stomach within 10 minutes. Positive scan was found to move along the intestine successively. 111In-Tf can be useful in assessing of hypoproteinemia of gastric cancer.

A 26-year-old male patient who had an 8 years history of recurrent peripheral edema with diarrhea and hypoproteinemia was evaluated. Endoscopic jejunal and ileal biopsy revealed markedly dilated mucosal lymph vessels with no evidence of inflammation. 99mTc-labeled human serum albumin (HSA) scintigraphy showed significant activity accumulating in the gastrointestinal tract to represent 99mTc-HSA leakage into the bowel lumen. A diagnosis of protein losing enteropathy and intestinal lymphangiectasia could be made. After treatment with a high protein and fat restricted diet, his symptoms subsided and the serum protein level was normalized.

A retrospective review of admission serum protein concentration in 18 children with hemolytic-uremic syndrome (HUS) showed significantly decreased serum total protein, albumin and globulin concentrations upon admission compared with 22 matched controls (P < 0.003). One child with atypical disease without diarrhea had normal serum protein concentrations. A strongly positive correlation (P = 0.006) was found between the age of HUS patients with diarrhea and their lowest total protein concentrations. In 10 children who eventually required hemodialysis, there was a significantly negative correlation (r = -0.8316, P = 0.01) between the admission serum albumin and the patients' highest creatinine levels, suggesting that hypoproteinemia may be a risk factor in the development of renal failure. The pathophysiological and clinical significance of hypoproteinemia in HUS needs further investigation.
