The postoperative results of 50 patients who underwent straight ileoanal anastomosis after total colectomy and mucosal proctectomy were compared with those of 74 patients who underwent ileal pouch--anal anastomosis. No deaths occurred. Of the straight ileoanal anastomoses, 32% failed because of sepsis or diarrhea and necessitated abdominal ileostomy; only 1.3% failed in the pouch-anal group (P less than .05). Stool frequency among patients followed up for three months or more (straight ileoanal, n = 30; pouch-anal, n = 33) was less in the pouch-anal group (mean +/- SEM, 7 +/- 1 stools per 24 hours) than in the straight ileoanal group (11 +/- 1/24 hr, P less than .01). Major nocturnal incontinence was also less in the pouch-anal group than in the straight ileoanal group (0% v 20%), and patient satisfaction was better, as measured on a scale of 1 (very poor functional result) to 10 (excellent result) (pouch-anal score, 9; straight ileoanal score, 6; P less than .02). We concluded that ileal pouch-anal anastomosis resulted in less diarrhea, better continence, and an improved quality of life when compared with straight ileoanal anastomosis.

In a study of early neonatal infection, 278 babies had a blood culture and an alpha 1-acid glycoprotein (alpha 1-AGP) determination. There were significant differences between the mean (+/- SEM) levels of alpha 1-AGP in infants who were noninfected (26 +/- 1.3 mg/dl, n = 244), infected (81 +/- 11 mg/dl, n = 12) and proved to have sepsis (66 +/- 10 mg/dl, n = 22). In the 'noninfected' group, alpha 1-AGP levels increased with postnatal age. Increasing levels were seen on the 1st day with both increasing gestational age (15-34 mg/dl from less than 30 to greater than or equal to 38 weeks) and birth weight (17-42 mg/dl from less than 1,000 to greater than or equal to 4,000 g), irrespective of the infant's sex. Among the sepsis group, infants who died had lower levels than those who survived (19 mg/dl vs. 90 mg/dl).

We reviewed diabetic gangrene in 104 American blacks and found that the clinical features were similar to those reported for the general diabetic population. We observed, however, that there was a significant association of hypertension with above-knee and bilateral amputations in our patients (P less than .001 and .01, respectively), and that the mean blood pressure of the bilateral amputees (124.5 +/- 3.8 mm Hg) (SEM) was significantly higher (P less than .005) than that of the unilateral amputees (114.4 +/- 1.7 mm Hg). There results suggest a strong association of hypertension with far-advanced occlusive vascular disease of the lower limbs. Moderately severe anemia (hematocrit 20% to 30%) was associated significantly with primary above-knee amputation and mortality (P less than .02 and .05, respectively). Mortality resulted mostly from mixed causes (cardiopulmonary failure, uremia, sepsis, diabetic coma). The dead patients had significantly increased prevalence of cardiac disease (P less than .02), higher frequency of above-knee amputation (P less than .01), and a duration of diabetes (17.4 +/- 2.8 years) significantly longer (P less than .025) than that of the surviving patients (12.0 +/- 1.0 years).

To characterize the role of the liver and kidney in the metabolic response to injury and infection, selective catheterization of the hepatic (42 veins) and renal veins (21 veins) was performed in 31 burn patients (mean burn size: 51% TBS), studied 4-129 days postinjury. Blood flow was determined by standard clearance techniques (ICG and PAH), and simultaneous arterial and hepatic and/or renal vein blood was obtained for oxygen, glucose, lactate, pyruvate, and amino acids. Patients studied in the first to third weeks postinjury were classified as noninfected (8 studies), bacteremic (8 studies), or bacteremic with complications (5 studies). There was no difference in age, weight, mean burn size, pulse rate, blood pressure, rectal temperature, total body oxygen consumption, or cardiac index among these groups. Estimated hepatic blood flow (EHBF) and hepatic substrate balance of these patients were compared with postabsorptive normal subjects in the literature (mean +/- SEM or range). :Formula: (See Text) Thermal injury alone resulted in marked increases in EHBF, hepatic oxygen uptake, and glucogenesis. The added insult of bacteremia significantly increased hepatic glucose output; as clinical sepsis progressed, glucose output decreased sharply. The kidney consistently demonstrated a net uptake of glucose in all studies. The changes in hepatic glucose output in bacteremic patients occurred without significant differences in EHBF, oxygen utilization or lactate uptake, but were associated with marked alterations in amino acid uptake.

We measured lymphocyte energy charge (LEC) in septic patients after hepatectomy to clarify the energy metabolism of lymphocytes in relation to arterial ketone body ratio (AKBR) reflecting the hepatic mitochondrial redox potential. Sixteen patients with AKBR above 0.7 (state A) tolerated their operations well without postoperative infectious episodes and their LEC (0.895 +/- 0.005, mean +/- SEM) was significantly (p < 0.001) higher than that (0.841 +/- 0.010) of 9 patients with AKBR from 0.7 to 0.4 (state B). Four of the 9 state B patients had multiple organ failure (MOF) with sepsis as a trigger. AKBR in 7 of 9 state B patients decreased and remained below 0.4 (state C). These state C patients showed significantly reduced LEC (0.781 +/- 0.024; p < 0.001, p < 0.05, compared with that in states A and B, respectively) and finally died of MOF with septic state. These results suggest that the severe and prolonged impairment of energy metabolism in the liver may be accompanied with the metabolic derangement of lymphocytes.

Adhesion molecules play a critical role in the interaction of circulating neutrophils with vascular endothelium during inflammation. Increased quantities of soluble, circulating intercellular adhesion molecule-1 (cICAM-1) are present in various inflammatory conditions. The purpose of this investigation was to measure cICAM-1 levels in septic adults, as well as to examine the relationship between this potential marker of endothelial-cell activation and the consequences of sepsis (i.e., multiple organ failure and death). Using a sandwich-type enzyme-linked immunosorbent assay (ELISA), we measured cICAM-1 in blood samples obtained within 12 h of admission to an intensive care unit (ICU) for sepsis and other conditions. We found cICAM-1 levels to be increased in 25 septic patients (1,259 +/- 159 ng/ml, mean +/- SEM) as compared with 12 healthy volunteers (355 +/- 41 ng/ml, p < 0.0001) and four ICU patients without systemic inflammatory response syndrome (SIRS) (585 +/- 76 ng/ml, p < 0.001). Twenty-five patients with SIRS but no evidence of causative infection also had elevated levels of cICAM-1 (937 +/- 144 ng/ml, p = 0.12 versus sepsis). Serial measurements over the first week of sepsis demonstrated persistent elevation in most patients. Day 1 cICAM-1 levels were higher (p = 0.017, ANOVA) in 16 patients with septic shock than in seven with severe sepsis and two with sepsis but without hypotension or hypoperfusion. There was a positive correlation (r = 0.50, p = 0.009) between Day-1 cICAM-1 measurements and severity of shock as determined by the presence of hypotension and vasopressor use.(ABSTRACT TRUNCATED AT 250 WORDS)

Triglyceride-rich lipoproteins bind and inactive bacterial endotoxin in vitro and prevent death when given before a lethal dose of endotoxin in animals. However, lipoproteins have not yet been demonstrated to improve survival in polymicrobial gram-negative sepsis. We therefore tested the ability of triglyceride-rich lipoproteins to prevent death after cecal ligation and puncture (CLP) in rats. Animals were given bolus infusions of either chylomicrons (1 g triglyceride/kg per 4 h) or an equal volume of saline for 28 h after CLP. Chylomicron infusions significantly improved survival (measured at 96 h) compared with saline controls (80 vs 27%, P < or = 0.03). Chylomicron infusions also reduced serum levels of endotoxin, measured 90 min (26 +/- 3 vs 136 +/- 51 pg/ml, mean +/- SEM, P < or = 0.03) and 6 h (121 +/- 54 vs 1,026 +/- 459 pg/ml, P < or = 0.05) after CLP. The reduction in serum endotoxin correlated with a reduction in serum tumor necrosis factor, measured 6 h after CLP (0 +/- 0 vs 58 +/- 24 pg/ml, P < or = 0.03), suggesting that chylomicrons improve survival in this model by limiting macrophage exposure to endotoxin and thereby reducing secretion of inflammatory cytokines. Infusions of a synthetic triglyceride-rich lipid emulsion (Intralipid; KabiVitrum, Inc., Alameda, CA) (1 g triglyceride/kg) also significantly improved survival compared with saline controls (71 vs 27%, P < or = 0.03). These data demonstrate that triglyceride-rich lipoproteins can protect animals from lethal polymicrobial gram-negative sepsis.

The present study was conducted to investigate changes in plasma membrane fluidity of the liver and kidney in sepsis, which is the main cause of multiple organ failure. Male Wistar rats weighing 200-250 g were used in all experiments. Sepsis was induced by cecal ligation and puncture. As a control, a sham operation was performed. The time course of plasma membrane fluidity of the liver and the renal cortex in septicemic rats or in controls was studied. To evaluate the fluidity, fluorescence polarization was measured using 1,6-diphenyl-1,3,5-hexatriene. The fluorescence polarization values of liver plasma membranes increased after cecal ligation and puncture: 0.183 +/- 0.004 (mean +/- SEM), 0.194 +/- 0.008, 0.206 +/- 0.003, and 0.210 +/- 0.002 at 0, 24, 48, and 72 hr, respectively. Corresponding values for membranes of the renal cortex increased in a similar fashion. To determine whether factors involved in cell membrane damage exist in blood, the direct effects of lipopolysaccharide (LPS), platelet-activating factor (PAF), and serum from normal rats or from septicemic rats on membrane fluidity were studied. The fluorescence polarization of plasma membranes of the liver or renal cortex to which septicemic rat serum was added was higher than that of plasma membranes to which normal rat serum was added. The fluorescence polarization of liver plasma membranes was increased by LPS, but that of plasma membranes of the renal cortex was slightly decreased. In addition, the fluorescence polarization of liver plasma membranes was increased by PAF, but that of plasma membranes of the renal cortex was decreased.(ABSTRACT TRUNCATED AT 250 WORDS)

Endotoxin sensitivity varies among animal species and appears to correlate with the presence of pulmonary intravascular macrophage (PIM). In rats, which lack PIM, we investigated the hypothesis that chronic cholestatic liver injury leads to induction of PIM and endotoxin sensitivity. Rats were randomized to either common bile duct ligation (BDL) or sham-surgery and studied at 1 wk (acute cholestasis), 2 wk (cholestasis, early cirrhosis), and 4 wk (cholestasis, established cirrhosis) after surgery. Intravascularly injected fluorescent latex microspheres (1 micron diameter) were taken up by large phagocytic cells in lung parenchyma of BDL rats (at 2 and 4 wk), while no uptake was observed in lungs from control rats. Electronmicroscopy revealed accumulation of large, mononuclear, macrophage-like cells containing ingested latex particles within the pulmonary capillaries. Pulmonary intravascular phagocytosis, as reflected in lung uptake of 99mTc microaggregated albumin (Microlite, mean particle diameter = 1 micron), averaged 0.7 +/- 0.1% (mean +/- SEM) of total injected dose in 13 control rats and progressively increased with time after BDL (1 wk, 1.7 +/- 0.2%; 2 wk, 10.0 +/- 3.0%; 4 wk 35.1 +/- 5.9%). Rats with biliary cirrhosis were markedly sensitive to the lethal effects of low dose endotoxin and demonstrated marked lung edema at the time of death. Furthermore, the lung uptake of intravascular 125I-lipopolysaccharide was increased five-fold in cirrhotic rats. We conclude that chronic biliary obstruction leads to the induction of pulmonary intravascular phagocytes and enhances endotoxin sensitivity in rats. Pulmonary intravascular phagocytosis in patients with advanced cirrhosis may account for their increased susceptibility to sepsis-induced adult respiratory distress syndrome.

Proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the procedure of choice for many children with ulcerative colitis and familial polyposis. The modified quadruple-limb (W) IPAA was designed to increase reservoir compliance and capacity, and to improve functional results by decreasing stool frequency. However, only limited information has been reported concerning the technical considerations and functional outcomes from W IPAA modification and utilization in the pediatric population. Additionally, pediatric IPAA physiological adaptation, expressed as IPAA volume/pressure relationships, for any type of IPAA design has not been described. In this report, the authors analyze their functional and physiological results with W IPAA in 19 children undergoing colectomy for ulcerative colitis and familial polyposis. Since 1986, 19 children (5 girls, 14 boys; mean age, 15.3 years [range, 11 to 18 years]) have undergone proctocolectomy with W IPAA for ulcerative colitis (n = 9) and familial polyposis (n = 10). IPAA pressure and volume profiles were measured in 10 patients at 2 and 12 months postileostomy takedown, and in five patients at 3 years. W IPAA compliance was calculated as the change in volume over change in pressure (delta V/delta P). There were no deaths, anastomotic leaks, or pelvic sepsis. The 24-hour stool frequency (mean +/- SEM) decreased significantly (P < or = .05) from 4.6 +/- 0.6 at 2 months to 3.3 +/- 0.1 at 12 months. No nighttime evacuation occurred after 12 months. W IPAA evacuation volume significantly increased (P < or = .05) from 238 +/- 22.9 mL at 2 months to 346 +/- 26.5 mL at 12 months and remained stable thereafter.(ABSTRACT TRUNCATED AT 250 WORDS)
