Patients who have previously experienced spontaneous bacterial peritonitis and have low-protein ascites (ascitic fluid albumin less than 1 g/dL [less than 10 g/L]) are candidates for long-term prophylactic therapy. Recommended regimens include either a single trimethoprim-sulfamethoxazole doublestrength tablet 5 days per week (Monday through Friday) or ciprofloxacin 750 mg once weekly.19,46 Any patient who has experienced an episode of variceal bleeding should also receive prophylactic antibiotics. 

The fluid and protein shift into the abdomen (called third-spacing) may be so dramatic that circulating blood volume is decreased, which causes decreased cardiac output and hypovolemic shock. Accompanying fever, vomiting, or diarrhea may worsen the fluid imbalance. A reflex sympathetic response, manifested by sweating, tachycardia, and vasoconstriction, may be evident. With an inflamed peritoneum, bacteria and endotoxins are absorbed easily into the bloodstream (translocation), and this may result in septic shock. Other foreign substances present in the peritoneal cavity potentiate peritonitis, notably feces, dead tissues, barium, mucus, bile, and blood. 

Goal calorie and protein requirements Perform a subjective global assessment Take into consideration the patient s current clinical status, diagnoses, medications, etc. Total daily calories -25-30 kcal/kg per day, or -1 500-1 800 kcal/day Protein -1.5-2 g/kg per day of ideal body weight (-89-11 8 g protein/day) This patient has sepsis, diffuse peritonitis, and recent surgical procedures, target -1800 kcal/day and -11 0 g protein/day... 

When bacteria become dispersed throughout the peritoneum, the inflammatory process involves the majority of the peritoneal lining. Fluid and protein shift into the abdomen (called third spacing ) may decrease circulating blood volume and cause shock. 

Daily protein intake should be 1.2 g/kg for patients undergoing hemodialysis and 1.2 to 1.3 g/kg for those undergoing peritoneal dialysis. 

Factors that influence drug dialyzability in chronic ambulatory peritoneal dialysis include drug-specific characteristics (e.g., molecular weight, solubility, degree of ionization, protein binding, and VD) and intrinsic properties of the peritoneal membrane (e.g., blood flow, pore size, and peritoneal membrane surface area). 

In an important study, Kirton et al. [5] engineered a mouse-human chimeric antibody and demonstrated that this was able to reduce leukocyte migration in various in vitro and in vivo mouse models. In particular, leukocyte migration to the peritoneal cavity was reduced by 40% in the thioglycollate inflammation model using mice expressing human SSAO/VAP-1 protein. The Finnish company Biotie Therapies Corporation, is in clinical development with an antibody to VAP-1 [54],... 

Rat peritoneal mast-cell exocytosis (as monitored by membrane capacitance measurements) in response to either antigenic stimulation or to the intracellular perfusion with guanine nucleotides (for example, GTP[AS]), occurs after a measurable lag period which has been suggested to be due to the involvement of a GTP-binding regulatory protein [202]. In contrast, stimula-... 

An alternative approach to clone the receptor was taken by Thomas and colleagues (1990, 1991). They screened a cDNA library from peritoneal rabbit cells with an antisense oligonucleotide probe deduced from the coding region of the second transmembrane domain, which is common to G-protein-coupled receptors (fMet-Leu-Phe is a G-protein-linked receptor). Screening of this library yielded a putative receptor clone F3R, characterised as follows ... 

Endometriosis is abnormal growth of endometrial tissue in the peritoneal cavity. Women with this disorder have dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility. Danazol (Danocrine) is a 2,3-isoxazol derivative of 17a-ethynyl testosterone (ethisterone) that has weak virilizing and protein anabolic properties. It is effective in endometriosis through its negative feedback... 

Pharmacokinetics Rapidly and completely absorbed from the GI tract. Protein binding less than 36%. Widely distributed (crosses the blood-brain barrier). Primarily excreted unchanged in urine. Not removed by hemodialysis or peritoneal dialysis. Half-life II-I5 hr (intracellular), 2-11 hr (serum, adults), 1.7-2 hr (serum, children). (Increased in impaired renal function). 

Pharmacokinetics Variably absorbed from the GI tract. Completely absorbed after IM administration. Protein binding 50%-60%. Widely distributed. Metabolized intracel-lularly in the liver. Primarily excreted in urine. Removed by hemodialysis but not by peritoneal dialysis. Half-life 8-12 hr (large doses, 8-15 hr). 

Rabbit peritoneal macrophages (po 15 mmHg) showed only half the SOD activity, expressed per mg protein, of the alveolar macrophages 150 mmHg). 

U- 4C]Pentachloroethane injected into the peritoneal cavity of male Wistar rats and BALB/c mice was found to bind to DNA (as well as RNA and proteins) in liver, stomach, lung and kidney. Adducts were not identified (Turina et al., 1989). 

Ascitic fluid derived from the peritoneal cavity of mice or rats that have been injected with hybridomas contain high concentrations of MAb (2—10 mg/mL), but this is usually mixed with variable amounts of blood cells, proteins, and fatty materials. It is therefore necessary to separate these components from the ascitic fluid before attempting purification of the MAb.
