Is faecal alpha 1-antitrypsin excretion a reliable screening test for protein-losing enteropathy?

Estimation of alpha 1-antitrypsin in random faecal samples has been suggested as a reliable index of intestinal protein loss. There was a poor correlation between faecal alpha 1-antitrypsin concentrations and simultaneously measured faecal loss of 51Cr-albumin in twenty adults with suspected protein-losing enteropathy. This indicates that faecal alpha 1-antitrypsin estimation may not be a valid screening test for protein-losing enteropathy.

Protein-losing enteropathy with congenital kidney stones in a 2-month-old boy: a rare case report and literature review.

BACKGROUND: Protein-losing enteropathy (PLE) is a rare condition featured by severe loss of proteins through the gastrointestinal tract. Rare PLE cases complicated with congenital kidney stones have been reported. This case study aimed to illustrate our experiences on the diagnosis and treatment of PLE and congenital kidney stones in a neonate. CASE PRESENTATION: A 10-day-old boy fed on breast milk presented to our department because of severe diarrhea, which showed no significant attenuation after free amino acid milk formula. Gastrointestinal endoscopy revealed absence of brush border of surface villi. Genetic testing was strongly recommended given intractable early-onset diarrhea, severe malnutrition and hypoalbuminemia. Then the patient was diagnosed with PLE based on the clinical manifestations and identification of DGAT1 gene by whole-exome sequencing. The patient underwent percutaneous suprapubic cystostomy to remove the urine, and ultrasonography examination showed kidney stones. CONCLUSIONS: We reported a rare newborn with PLE and congenital kidney stones carrying DGAT1 mutations.

Diagnosis of protein-losing enteropathy by gastrointestinal clearance of alpha1-antitrypsin.

Alpha1-antitrypsin was assessed, in 10 patients with protein-losing enteropathy and 13 control subjects, as an endogenous marker of plasma-protein loss into the gastrointestinal tract. Both faecal alpha1-A.T. concentrations and faecal alpha1-A.T. clearance were significantly higher in patients than in controls. Wtih clearance there was no overlap between the groups. Over 10 days the normal gastrointestinal clearance of alpha1-A.T. was 3.07 +/- 2.25 (S.D.) ml/day. Measurement of alpha1-A.T. clearance is easy and requires no radioisotopes.

Case report: intestinal clearance of calcium and protein in Waldenstrom's macroglobulinemia.

A 63-year-old man with Waldenstrom's macroglobulinemia had severe steatorrhea, marked protein-losing enteropathy, and excessive endogenous fecal calcium clearance. The malabsorption and protein loss resulted in weight loss and hypoalbuminemia. In contrast, the striking enteric calcium loss was completely compensated by an increase in calcium absorption resulting in a positive calcium balance.

Protein digestion and absorption in man. Normal mechanisms and protein-energy malnutrition.

Protein is an essential nutrient normally assimilated in an efficient manner following the action of gastric, pancreatic and small intestinal enzymes. After hydrolysis, protein digestion products in the form of amino acids and small peptides undergo mucosal uptake by distinct transport mechanisms. Although gastric and pancreatic enzymes are important, the small intestine appears to be the critical rate-limiting tissue in this process. Impaired intake, assimilation or excessive enteric protein loss may occur with several diseases leading to protein-energy malnutrition. Although the clinical and laboratory features of this condition are nonspecific and wide ranging in spectrum, their presence may provide a clue to underlying disease and serve as an index of patient nutritional status. Disease of the exocrine pancreas or small intestine may cause significant protein-energy malnutrition which, in turn, can cause major structural and functional abnormalities in these tissues.

Disorders of chloriuretic hormone secretion.

Experimental evidence supports the existence of a circulating substance, natriuretic hormone, which augments electrolyte excretion. Because such a hormone probably acts by inhibiting chloride reabsorption in the thick, ascending limb of the loop of Henle it would more accurately be called chloriuretic hormone. Chloriuretic hormone must have an action which resembles that of loop diuretics such as frusemide and ethacrynic acid. An excess of chloriuretic hormone could explain all the manifestations of Bartter's syndrome, whereas a deficiency could account for Gordon's syndrome. Hyporeninaemic hypoaldosteronism may develop in subjects who are unable to increase chloriuretic hormone concentrations appropriately in response to progressive impairment of renal function.

Transient intestinal lymphangiectasia.

Intestinal lymphangiectasia may be more protean in clinical manifestations and less rare than earlier suspected. A recent report points out that there are two types of the disorder, one congenital and the other acquired and transitory. A case is reported which fulfills the current clinical, laboratory, radiological and histological criteria for the diagnosis of the disease, and represents the first report in Scandinavia of transient intestinal lymphangiectasis with rapid and complete recovery within a few months after initiation of MCT diet.

Intestinal lymphangiectasia. Long-term results with MCT diet.

The clinical course of 6 children with primary intestinal lymphangiectuasia who have been treated with low fat medium chain triglyceride-supplemented diets for between 3 and 8 years (4 for longer than 5 years) is described. Though laboratory findings indicate continuing chyle leak, evidence for long-term benefit from dietary treatment is provided by symptomatic relief while on the diet, clinical relapse upon relaxation of t,e regimen, and improvement in growth rates. In most patients the underlying lymphatic defect, and thus the need for dietary treatment, appears to be permanent.

[Protein changes in the jejunal juice and endointestinal exudation of albumin-I 131 in acute infectious enterocolitis].

The phenomenon of endointestinal protein exudation in acute infectious enterocolitis is studied. Total proteins were determined in 30 cases of acute enterocolitis and 50 of bacillary dysentery in the acute stages of the disease and convalescence. The proteinogram of the jejunal juice was performed in the acute stage and convalescence in 20 patients. In 16 patients and 5 controls endointestinal albumin elimination was determined quantitatively by means of 131I labeled albumin. The results showed increase in the total protein content in the jejunal juice in the course of acute infectious enterocolitis and bacillary dysentery and a return to normal values in convalescence. Electrophoresis of the jejunal juice in acute infectious enterocolitis showed the absence of fraction III with alpha1-globulin migration, and increased fractions I, II and IV probably due to the loss of endointestinal albumin, also confirmed by quantitative albumin determinations with 131I labeled albumin. In conclusion, patients with acute infectious enterocolitis present a marked loss of endointestinal albumins in the acute stage of the disease, with a return to normal values in convalescence.

[Pathogenesis, clinical manifestations and treatment of the "postgastrectomy-syndrome" (author's transl)].

The incidence rate of complications in patients, who underwent stomach resection as surgical treatment procedure is rather high (20%). Postprandial syndromes (dumping syndrome, lactose-intolerance, afferent loop-syndrome), malabsorption syndromes (anemia, osteopathia, steatorrhea, protein deficiency) and late organic manifestations (anastomotic and suture ulcers, retrograde intussusception, gastric-stump carcinoma) were usually summarized as "postgastrectomy syndrome". A review of pathogenesis, symptoms and therapeutic approach for the various postoperative disorders is given. Selective proximal vagotomy as the surgical treatment procedure of choice is emphasized.
