A young woman presented with high fever and edema in January, 1984, and was diagnosed as having systemic lupus erythematosus. Prednisolone administration failed to improve her symptoms. In May she was admitted to hospital because of elevated erythrocyte sedimentation rate (ESR), hypoproteinemia, hypogammaglobulinemia, hypocomplementemia, positive antinuclear antibody, elevated immune complex level, and diarrhea. Edema disappeared following administration of diuretics and albumin, although the pathogenesis was still undetermined. In September, she was referred to our institution because of severe watery diarrhea and hypoproteinemia. Endoscopic examination showed a diffuse inflammatory lesion in the duodenum and the colon. Radioisotopic 51Cr-albumin study results were compatible with protein-losing enteropathy. Hypoproteinemia and inflammatory changes of the intestine were improved by antibiotics, suggesting that the inflammatory lesion was caused by bacterial infection. Despite the improvements in clinical symptoms and laboratory findings, the serum IgA level was still low and the thrombocytopenia remained. The morphological characteristics of the megakaryocytes were consistent with idiopathic thrombocytopenic purpura. In May, 1986, the thrombocytopenia deteriorated, causing purpura. Prednisolone was administered again, and this resulted in normalization of the platelet count, although the IgA level remained low. Finally the prednisolone was stopped, and the IgA level gradually recovered, with the improvement of the enterocolitis. The exact pathogenesis of the whole picture in this case is unclear, but an 8-year-long clinical course suggests that the protein-losing was caused by an infectious enterocolitis superimposed on IgA deficiency.

A 26-year old woman, who was diagnosed as having systemic lupus erythematosus at the age of 23 year old, presented diarrhea and headache. She showed severe hypoproteinemia (serum total protein 3.7 g/dl, serum albumin 1.4 g/dl) and hyperlipidemia. She revealed to have protein-losing enteropathy with the result of alpha-1-antitrypsin clearance test using stool. Increase of prednisolone improved the loss of albumin into the bowel and abnormal laboratory findings. She also showed watershed infarction in the area of middle cerebral artery and posterior cerebral artery. Protein-losing enteropathy is a rare complication of SLE, only 18 cases are available on literature. No case is found to have cerebral infarction in patients with protein-losing enteropathy associated with SLE. It is known that blood levels of anticoagulation factors decrease in protein-losing enteropathy due to the leakage of plasma protein into intestinal lumen. Serum antithrombin III was decreased in this case. Hyperlipidemia found in this case seems to be caused by same mechanism in nephrotic syndrome. Lupus anticoagulant was also positive in this patient. These factors seems to be related to the occurrence of cerebral infarction. This case suggests the possibility of cerebral infarction in patients with protein-losing enteropathy in SLE.

Simian immunodeficiency virus infection of macaques is a model for human immunodeficiency virus infection of humans. In vivo-titrated stocks of SIV are essential for the utilization of this model for vaccine development. The elicitation of anti-human cell antibodies by some vaccines prepared in human cells and the related protective effects of the vaccine produced in human cells suggest a need for new macaque-derived SIV stocks. Here we describe the titration and characterization of two stocks of SIVmac that were produced in primary rhesus macaque cells. The first virus is SIVmac251, isolated from tissues of macaque 251, and the second is a molecular clone designated as SIVmac239. A 50% rhesus monkey infectious dose (MID50) was titrated for each virus stock by intravenous inoculation. An additional five macaques were inoculated with 10 MID50 of the SIVmac251 stock and were followed for disease outcome. All five monkeys developed antigenemia by 14 days postchallenge. Two of the five monkeys developed strong anti-SIV humoral immunity, whereas three developed little or no humoral immunity. As has been observed previously, the rapidity of disease progression correlated with the lack of a strong antibody response. The three animals with low humoral immunity died within 7 months of challenge, with antigenemia, cachexia, hypoproteinemia, hypoalbuminemia, weight loss, and intractable diarrhea, while maintaining their circulating CD4 numbers. One animal died at 1.5 years of more typical simian AIDS.

Enterokinase is a glycoprotein and is now designated enteropeptidase (E.C.3.4.4.8.). It is present in the duodenal and jejunal mucosa. Pancreatic proteolytic enzymes are secreted as proenzymes. Enterokinase converts trypsinogen to trypsin in the duodenal lumen. Duodenopancreatic reflux of duodenal enterokinase may be important in the pathogenesis of experimental and clinical acute pancreatitis. Congenital enterokinase deficiency is a distinct clinical entity characterized by diarrhea, failure to thrive, hypoproteinemia, and edema. Acquired enterokinase deficiency may occur in some diffuse small bowel diseases. Steatorrhea of celiac spruce may be due partly to the fact that deficiency of secretin and cholecystokinin may interfere with the action of enterokinase. The interrelationship between secretin, cholecystokinin, enterokinase, and bile salts is not completely understood.

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 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.

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.

We present a 72-year-old man who had episodes of severe, acute renal failure during severe attacks of diarrhea caused by Vibrio cholerae. Patterns of acute tubular necrosis and tubulointerstitial nephritis developed following hypotension and decrease in renal blood flow, causing secondary renal ischemia. There was severe dehydration with profound hypovolemia and infection. The clinical picture included fever, weakness, arthralgia, pedal edema, mild bilateral pleural effusions, anemia, leukocytosis, azotemia with a maximum of 330 mg/dl of urea, creatine to a maximum of 9.8 mg/dl, hypoproteinemia, severe metabolic acidosis, marked increase in lactate dehydrogenase (LDH) and creatine phosphokinase (CPK), microscopic hematuria, sterile leukocyturia, normoglycemic glucosuria and phosphaturia with diminished tubular reabsorption of phosphorus. A short oliguric phase was followed by a polyuric phase lasting about 10 days, and glomerular and tubular function became normal after about 3 weeks. Treatment was by intensive infusions of fluids, electrolytes, sodium bicarbonate, salt-free albumin and antibiotics. To the best of our knowledge, this renal complication of cholera has not yet been described in Israel.

In order to examine the clinical characteristics and genetic background of secondary amyloidosis associated with rheumatoid arthritis, we analyzed clinical features and HLA typing of 85 patients in a multicenter study. Eighty-five patients with secondary amyloidosis associated RA were studied. The diagnosis of secondary amyloidosis were made on histological findings by biopsy or autopsy. The most common biopsy site was gastrointestinal tract (79.5%). Clinical symptom and the frequency at the time of diagnosis were; diarrhea (35 cases), abdominal pain (22 cases) and vomiting and nausea (16 cases). Abnormalities and the frequency in a laboratory test included proteinuria (49 cases), increased serum creatinine (32 cases), anemia (30 cases) and hematuria (15 cases). Twenty-eight patients were dead and 57 patients were alive at the time of the study. The average duration between diagnosis of amyloidosis and death was 19.4 +/- 18.5 (SD) months among the dead patients. The average duration after diagnosis of amyloidosis was 24.2 +/- 19.5 (SD) months in surviving patients. The causes of death were renal failure complicated with heart failure (6 patients), heart failure alone (3 patients) and renal failure alone (2 patients). Fifty-nine patients in the control group who were negative to amyloid deposition on biopsies at more than one site in the gastrointestinal tract, were clinically compared with patients in the amyloidosis group. No difference were noted in the age of RA occurrence and the stage between the two groups. As to the class, however, the number of patients with severe functional disorder (class 3 or severe) was larger in the amyloidosis group. There were no significant difference between the two groups in Lansbury's activity index. On hematology, biochemistry and urinalysis, the incidences of increased white blood cell count, anemia, increased platelet count, increased serum creatinine, hypoproteinemia, hypoalbuminemia, increased IgA, and increased urine and blood BMG were statistically significantly higher in the amyloidosis group than in the control group. HLA-A, -B, -C, and DR-locus antigens were compared in the 53 patients in the amyloidosis group and in the 59 subjects in the control group. There were no significant differences in frequency of HLA-A, and -B antigens between two groups. Frequency of CW7 antigen was significantly decreased in the amyloidosis group (13.2%) than in the control group (39.0%). Frequency of DR1 antigen was decreased in the amyloidosis group (3.8%) than in the control group (22.0%), although the difference was not significant. These findings suggest the possible involvement of genetic factors in the occurrence of amyloidosis. It is suggested that the occurrence of amyloidosis is suppressed by some genes which are linked with CW7 antigen.

A 77-year-old woman was hospitalized repeatly due to frequent hemoptysis and production of bloodly sputum for several years. Bronchography in 1989 revealed bronchiectasis. She had complained of abdominal pain and diarrhea since 1991, and her urine was first positive for protein in 1992. She was admitted to our hospital in October 1992 because of edema, anemia, and hypoproteinemia. Despite treatment, renal dysfunction and the gastrointestinal disorder progressed and she died in January 1993. An autopsy revealed diffuse depositions of amyloid in many organs, especially in the kidney and the gastrointestinal tract. This amyloid protein was identified as AA protein, which was suggestive of secondary amyloidosis. Bronchiectasis appears to have been the disease underlying this patient's amyloidosis.
