Whole body protein synthesis and catabolism in septic man. 1977

C L Long, and M Jeevanandam, and B M Kim, and J M Kinney

The protein catabolic response to sepsis has been measured in three patients and in two normal subjects using a pulse injections of L-[15N]alanine. In addition, the urea kinetics were measured using a pulse administration of [15N]urea. Several nitrogen models which simulated the metabolic pathways of nitrogen-labeled compounds were tried. Best curve fits and acceptable confidence limits were obtained with a four-pool model containing two metabolic pools and two urea pools. Using this model, synthesis and catabolism rates were calculated for a fast and slow protein turnover pool. The mean daily total protein synthesis rate in the normal was 3.695 g/kg compared to 4.479 g/kg in sepsis. Because all subjects were in negative nitrogen balance, the mean total protein catabolic rate in the normal was 4.379 g/kg, compared to 5.298 g/kg in sepsis. These data suggest an increase in both protein synthesis and catabolism during sepsis.

D007081	Ileostomy	Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.

D007410	Intestinal Diseases	Pathological processes in any segment of the INTESTINE from DUODENUM to RECTUM.	Disease, Intestinal,Diseases, Intestinal,Intestinal Disease
D007412	Intestinal Fistula	An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).

D010537	Peritoneum	A membrane of squamous EPITHELIAL CELLS, the mesothelial cells, covered by apical MICROVILLI that allow rapid absorption of fluid and particles in the PERITONEAL CAVITY. The peritoneum is divided into parietal and visceral components. The parietal peritoneum covers the inside of the ABDOMINAL WALL. The visceral peritoneum covers the intraperitoneal organs. The double-layered peritoneum forms the MESENTERY that suspends these organs from the abdominal wall.

D010538	Peritonitis	INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.

D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
