The authors studied the assimilation of nitrogen preparations--moriamin S-2 and "improved" caseine hydrolysate in parenternal administration to 100 albino rats. Healthy animals and those with toxic affection of the liver induced with CCl4 were experimented upon. In healthy animals administration of nitrogen preparations led to the change of negative nitrogen balance into a positive one, normalized the content of blood and tissue amine nitrogen deranged in
protein deficiency
. Assimilation of nitrogen preparations fell considerably in toxic hepatitis. An 8-day parenteral nutrition failed to change the negative nitrogen balance into positive, and did not eliminate
hypoproteinemia
; however, it normalized the amine nitrogen concentration in the blood and tissues.

Exocrine pancreatic secretion was studied in 9 patas monkeys before and during protein depletion, and in 4 of them also during recovery from protein depletion. Pancreatic function was estimated by measuring enzymatic activities in the duodenal contents after a test meal and by determination of urinary excretion of p-aminobenzoic acid (pancreatic function test) after oral ingestion of the chymotrypsin-labile peptide N-benzoyl-L-tyrosyl-p-aminobenzoic acid. The average serum albumin dropped by 34.8% to 2.6 g per 100 ml. Significant decrease of trypsin, lipase, amylase, and chymotrypsin was observed in the duodenal samples during
protein deficiency
. Urinary excretion of p-aminobenzoic acid was also reduced significantly. The two tests correlated well. In 3 of 4 animals, recovery of pancreatic function was noted after refeeding a full protein diet. Pancreatic atrophy was noted in 2 animals which died. The study shows that exocrine pancreatic secretion can be seriously impaired even at a moderate
protein deficiency
and may not be reversibly in all instances. Therefore, function tests have to be evaluated with caution when
hypoproteinemia
, i.e., hypoalbuminemia, is present.

Malnutrition is observed in 60 p. cent of patients with alcoholic cirrhosis. It is characterized by weight loss,
hypoproteinemia
, and a negative nitrogen balance. It is due to multiple causes. This malnutrition increases the risk of disturbances in the immune system, susceptibility to infection, and postoperative complications. Re-nutrition by standard methods of feeding often is inadequate or impractical. Use of artificial nutrition is often made necessary either by enteral or parenteral route. A controlled study of parenteral nutrition did not make it possible to correct weight loss and
protein deficiency
in these patients. Laboratory tolerability, except for increased BUN was always excellent. Enteral nutrition, easier to administer, which appears less dangerous and more natural, has not demonstrated its efficacy either.

A case of tricuspid regurgitation (TR) complicated by severe
hypoproteinemia
is presented herein. A 68-year-old man who had undergone coronary artery bypass grafting (CABG) for postinfarction angina suffered repeated inferior myocardial infarction due to obstruction of the proximal right coronary artery, 3 years after which he developed systemic edema. Investigations revealed TR associated with
hypoproteinemia
; however, treatment consisting of aggressive diuretic therapy and albumin administration proved ineffective. The
hypoproteinemia
manifested as protein-losing enteropathy clinically, and the tricuspid valve was replaced to eliminate high venous pressure. The serum protein levels became normalized after the operation. Although TR is generally well tolerated in the absence of pulmonary hypertension, surgical management is recommended for patients with severe
protein deficiency
resistant to medical treatment.

Malnutrition affects millions of children in developing countries, compromising immunity and contributing to increased rates of death from infectious diseases. Rotavirus is a major etiological agent of childhood diarrhea in developing countries, where malnutrition is prevalent. However, the interactions between the two and their combined effects on immune and intestinal functions are poorly understood. In this study, we used neonatal gnotobiotic (Gn) pigs transplanted with the fecal microbiota of a healthy 2-month-old infant (HIFM) and fed protein-deficient or -sufficient bovine milk diets.
Protein deficiency
induced
hypoproteinemia
, hypoalbuminemia, hypoglycemia, stunting, and generalized edema in Gn pigs, as observed in protein-malnourished children. Irrespective of the diet, human rotavirus (HRV) infection early, at HIFM posttransplantation day 3 (PTD3), resulted in adverse health effects and higher mortality rates (45 to 75%) than later HRV infection (PTD10). Protein malnutrition exacerbated HRV infection and affected the morphology and function of the small intestinal epithelial barrier. In pigs infected with HRV at PTD10, there was a uniform decrease in the function and/or frequencies of natural killer cells, plasmacytoid dendritic cells, and CD103
+
and apoptotic mononuclear cells and altered gene expression profiles of intestinal epithelial cells (chromogranin A, mucin 2, proliferating cell nuclear antigen, SRY-Box 9, and villin). Thus, we have established the first HIFM-transplanted neonatal pig model that recapitulates major aspects of protein malnutrition in children and can be used to evaluate physiologically relevant interventions. Our findings provide an explanation of why nutrient-rich diets alone may lack efficacy in malnourished children.
IMPORTANCE
Malnutrition and rotavirus infection, prevalent in developing countries, individually and in combination, affect the health of millions of children, compromising their immunity and increasing the rates of death from infectious diseases. However, the interactions between the two and their combined effects on immune and intestinal functions are poorly understood. We have established the first human infant microbiota-transplanted neonatal pig model of childhood malnutrition that reproduced the impaired immune, intestinal, and other physiological functions seen in malnourished children. This model can be used to evaluate relevant dietary and other health-promoting interventions. Our findings provide an explanation of why adequate nutrition alone may lack efficacy in malnourished children.

Protein-losing enteropathy (PLE) is characterized by loss of serum proteins into the gastrointestinal tract. It may lead to
hypoproteinemia
and clinically present as
protein deficiency
edema, ascites, pleural or pericardial effusion and/or malnutrition. In most cases the site of protein loss is the small intestine. Here we present an unusual case of severe PLE in a 55-year old female with a one-year history of recurrent diarrhea, crampy abdominal pain, and peripheral edema. Endoscopy and MRI showed a diffuse inflammatory thickening of the sigmoid colon and the rectum. Surgical resection of the involved colon was performed and the symptoms were significantly resolved. The final histologic evaluation confirmed a diagnosis of a pseudomembranous colitis with cap polyposis-like features. Such a cause of PLE has never been described before.
