1/2. lymph loss in the bowel and severe nutritional disturbances in Crohn's disease.A severe nutritional deficiency status is described in a 22-year-old patient with Crohn's disease. The clinical picture on admission was dominated by an episode of gastrointestinal bleeding secondary to clotting disturbances (vitamin k deficiency) and severe cachexia due to a protein energy malnutrition. The mechanisms of severe nutritional disturbances in Crohn's disease are multifactorial. In this patient, lymphatic leakage into the intestinal lumen was a major contributing factor in the pathogenesis of protein-losing enteropathy, fat malabsorption, and lymphocytopenia. The authors were able to demonstrate this intestinal lymph loss by nuclear imaging.- - - - - - - - - - ranking = 1keywords = malnutrition (Clic here for more details about this article) |
2/2. Studies of tryptophan and albumin metabolism in a patient with carcinoid syndrome, pellagra, and hypoproteinemia.Detailed studies of protein metabolism were undertaken in a patient with pellagra and hypoproteinemia associated with the carcinoid syndrome both before and after treatment. The synthesis of albumin improved from 82 mg per kg per day to 135 mg per kg per day with little change in the daily excretion of 5-hydroxyindole acetic acid. After treatment with nicotinamide the patient made good progress with a complete resolution of the signs of pellagra and protein malnutrition. These results support the hypothesis that a reduced availability of the essential amino acid L-tryptophan may limit the synthesis of albumin and nicotinic acid in patients with the carcinoid syndrome who become anoretic.- - - - - - - - - - ranking = 1keywords = malnutrition (Clic here for more details about this article) |
