Serum concentrations of free fatty acids (FFA) were assayed in 20 patients with acute necrotizing
pancreatitis
(ANP). Pancreatic and peripancreatic fat necrosis was verified on operation and/or by contrast-enhanced computed tomography. For comparison, 20 patients with acute edematous
pancreatitis
(AEP) were examined. On admission, FFA serum levels were 1.14 +/- 0.12 (SEM) mmol/L in ANP and, thus, significantly (p < 0.03) higher than in AEP (0.78 +/- 0.09 mmol/L). The two groups also differed in the later course: in ANP, the FFA values remained raised (d 5-11:0.86 +/- 0.13 mmol/L; p > 0.05 vs day 1), whereas in AEP, the FFA concentrations normalized within 1 wk (d 2-4:0.52 +/- 0.11 mmol/L; d 5-11:0.39 +/- 0.05 mmol/L; p < 0.05 vs day 1 and p < 0.01 vs ANP). Serum FFA correlated positively with C-reactive protein levels (rs = 0.42; p < 0.01), but has less discriminating potency between ANP and AEP. In AEP, the initial peak may correspond to the disease outburst itself and to unspecific stress. In ANP, the higher and sustained elevation of FFA may predominantly mirror the ongoing pancreatic parenchymal and extrapancreatic fat necrosis, and be pathophysiologically relevant, especially in view of significantly reduced
serum albumin
levels in ANP.

Bacterial infection increases mortality and morbidity in acute pancreatitis. The aim of the present study was to analyze possible mechanisms by which bacterial infectious complications may worsen the course of the disease. Systemic arterial pressure, mucosal microcirculation, and intestinal, peritoneal, and pulmonary permeability of 125I-labeled human
serum albumin
were measured 3, 6, 12, 24, 48, and 72 h after sham operation, induction of
pancreatitis
(AP), abdominal sepsis (AS), or AP+AS. The mortality rate at 48 and 72 h was 33% in AS and 58 and 75%, respectively, in AP+AS, whereas there were no deaths in the AP or sham-operated groups. The systemic arterial pressure and intestinal blood flow decreased early in all study groups, with the lowest values for AP+AS. Bacterial infection aggravated the increase in intestinal, peritoneal, and pulmonary permeability to labeled albumin in
pancreatitis
. This was true for both intestinal endothelial permeability (blood to tissue) and mucosal barrier permeability (blood to lumen). The findings demonstrate the occurrence of circulatory failure and changes of the capillary barrier in multiple organs in acute pancreatitis. Moreover, the changes were aggravated by an intraabdominal septic challenge. The observations imply that bacterial infection may play a role in the development of multiple organ failure in acute pancreatitis, tentatively by aggravating alterations in tissue barrier function.

The nature of the gastrointestinal injury following bone marrow transplantation and its clinical and nutritional sequelae are poorly defined. Prospective assessments of gastrointestinal function, nutritional status, and wellbeing were therefore carried out in 47 consecutive patients (28 males, 19 females; mean age 8.4 years) undergoing bone marrow transplant. 31 diarrhoeal episodes (median duration 9.5 days) occurred in 27 patients at a median of 10 days after transplantation. Ninety one per cent of episodes were associated with protein losing enteropathy. Protein losing enteropathy was more severe in graft-versus-host disease (GVHD) comparing with other causes. It led to a substantial fall in
serum albumin
and there was a negative correlation between faecal alpha 1-antitrypsin concentrations and
serum albumin
. Transient pancreatic insufficiency developed in 18 patients, and
pancreatitis
in one. Intestinal permeability was normal in 12 patients who had no diarrhoea during the conditioning treatments. Diarrhoeal patients had a significantly greater decrease in nutritional status and wellbeing than patients without diarrhoea. Gastrointestinal injury following bone marrow transplantation is thus complex. Severe protein losing enteropathy in this context suggests the presence of GVHD.

Gastrointestinal tract failure may be involved in the development of systemic septic complications in acute pancreatitis. Systemic and intestinal circulation, intestinal permeability and absorptive function were evaluated in the early course of acute pancreatitis induced in rats by retrograde intraductal injection of 0.2 ml of 5 per cent sodium taurodeoxycholate and 0.4 nmol trypsin. A decrease in systemic arterial pressure and intestinal blood flow and an increase in intestinal permeability as measured by the leakage of 125I-labelled human
serum albumin
from blood to lumen were noted in the distal ileum and colon, reaching statistically significant differences 6 h after induction of
pancreatitis
. The transport of small molecular markers (sodium fluorescein and 51Cr-labelled ethylenediamine tetra-acetic acid) through the distal ileum and colon in vitro from the mucosal to the serosal site in Ussing chambers significantly increased in the early periodic (20-60 min) of incubation, while the passage of a macromolecular marker (ovalbumin) demonstrated a definite increase at 60-120 min of incubation. D-Xylose absorption from the gut lumen to the portal vein was significantly less in acute pancreatitis than after sham operation. Intravenous administration of the hydroxyl radical scavenger dimethylsulphoxide prevented the compromised intestinal permeability and gut absorptive capacity induced by acute pancreatitis, but did not affect the reduced arterial pressure and intestinal microcirculation. Cytotoxic oxygen-derived free radicals may contribute to the development of alterations in intestinal permeability and absorptive function found in the early stage of acute pancreatitis in the rat.

Bacterial translocation (BT) from the gastrointestinal tract to mesenteric lymph nodes (MLN) and other extraintestinal organs is an important source of infection in acute pancreatitis (AP). Epidermal growth factor (EGF), a peptide hormone with trophic effects on gut mucosa, has decreased intestinal mucosal injury in septic rats and decreased burn-induced BT in mice. The purpose of this study is to examine whether EGF could affect BT in acute necrotizing
pancreatitis
. Forty-eight male Sprague-Dawley rats (250-350 g) were studied. AP was induced in Group I and Group II by pressure injection of 3% taurocholate and trypsin into the biliopancreatic duct (1 ml/kg of body weight). Group III and Group IV underwent laparotomy without induction of acute pancreatitis. Group I rats received human recombinant EGF (100 micrograms/kg, subcutaneously twice daily) and Group II rats received a similar volume of 0.1% bovine
serum albumin
as a placebo postoperatively. Group III and Group IV received EGF and placebo, respectively. At 48 hr postoperatively, blood was drawn for culture and amylase determinations. Jejunum and ileum were obtained to measure mucosal protein content, mucosal thickness, villus height, and crypt depth. Specimens from MLN, spleen, liver, pancreas, and cecum were harvested for pathology and culture of gram positive (G+), gram negative (G-), and anaerobic bacteria. Ileal mucosal protein levels were increased significantly in Group I (1.96 +/- 0.14 mg/cm) compared to Group II (0.95 +/- 0.15 mg/cm intestinal segment) (P < 0.01). Jejunal and ileal mucosal thickness, villus height, and crypt depth in Group I were significantly increased when compared to Group II (P < 0.05). All 12 rats in Group II had BT to MLN compared to 58% (7 of 12 rats) in Group I (P < 0.05). Thirty-three percent (4 of 12 rats) had BT to distant sites such as pancreas, spleen, liver, and/or blood in Group I vs 83% (10 of 12 rats) in Group II (P < 0.05). EGF treatment minimizes intestinal damage, decreases BT to MLN and bacterial spread to distant sites, and may be beneficial in preventing septic complications in AP.

While hypovolemia or hypovolemic shock is dominant in the early stage of severe acute pancreatitis, there have been few studies on the effects of hypertonic solutions in the management of this disease. We conducted this study to evaluate the therapeutic effects of hypertonic saline solutions (HS) on the course of severe acute pancreatitis in rats.
Pancreatitis
was induced in male Wistar rats by injecting a 5% solution of sodium taurocholate into the biliopancreatic duct. The effective circulating plasma volume (ECPV) was measured using radioiodinated [125I]bovine
serum albumin
. Samples of blood and of ascitic fluid were obtained 3, 6, and 12 h after the onset of
pancreatitis
. Lactated Ringer's solution (LR) and HS were administered consecutively for 3 h beginning 3 h after the induction of
pancreatitis
. ECPV was measured 6 h after the onset of
pancreatitis
. The survival rates were investigated for up to 10 days. The mean ECPV decreased significantly from 24.9 +/- 1.1 ml/kg before disease onset to 11.5 +/- 1.3 ml/kg 6 h postoperatively. LR failed to achieve a normal value for ECPV even following a 150 ml/kg infusion. HS200 and HS300 restored the ECPV to the normal level, and with smaller volumes infused. All rats in the untreated group died within 3 days. LR and HS improved the survival rates, with the infusion of HS200, 100 ml/kg, thus attaining a 45% survival at 10 days.

Severely malnourished children afflicted by acute lymphoblastic leukemia (ALL), particularly in developing countries, have reduced tolerance to chemotherapy and a compromised prospect for survival. We investigated the prevalence and severity of alterations in growth and nutritional status in children with ALL from population-based referral areas in Canada. All children were treated with Dana-Farber Cancer Institute ALL Consortium protocols. First, the relative impact of cranial irradiation (CI) and chemotherapy on growth was studied in 116 children at diagnosis and at 6-month intervals during treatment. We observed a decline in height standard deviation (SD) score in the first year in all children, and a further decline in height SD score during the second year only in the children who received CI. Weight reduction occurred in the first year, but during the second year there was a disproportionate increase in weight compared with height, suggesting that children treated with ALL have a tendency toward obesity. Both chemotherapy and CI contribute to the altered growth observed in children treated for ALL. Second, intestinal functional integrity was assessed in 16 children during post-induction chemotherapy. Nutrient intake was adequate and there was minimal evidence of malabsorption: fat malabsorption occurred in only 1 child (after treatment-related
pancreatitis
), abnormal D-xylose absorption occurred in 2 children at 6 months of therapy (returning to normal 6 months later) and abnormal lactose absorption occurred in 4 children. Third, weight, height, whole body lean and fat mass measured by dual-energy X-ray absorptiometry and
serum albumin
were determined at diagnosis and at 6-month intervals throughout therapy in 19 children with ALL. Height SD scores decreased significantly during treatment.
Serum albumin
was abnormally low in 6/19 at diagnosis and 14/18 during intensive consolidation therapy. The mean change in the ratio of lean mass to total body weight showed a 5% reduction by 6 months of therapy. Body fat increased from a mean of 22% at diagnosis to 28% at completion of therapy. The majority of children treated for ALL thus have significant changes in nutritional status manifested by reductions in growth, alterations in lean and fat body mass and abnormally low serum proteins during intensive therapy.

A relationship between of acute pancreatitis severity and concentrations of blood transporters of nonesterified fatty acids (albumin) and esterified fatty acids (lipoproteins) was studied. In necrotizing
pancreatitis
, there was a positive correlation between decrease of albumin and lipoprotein concentrations in serum, but no correlation was in edematous
pancreatitis
. High levels of
serum albumin
(> 32 g/L) and lipoproteins (cholesterol + triglycerides, CH + TG, > 260 mg/dL) had good prognostic value in terms of favourable development of this disease, whereas lower concentrations indicated unfavourable prognosis. Both albumin and lipoproteins appeared in the peritoneal exsudate where they represented 73 and 53% of the serum concentrations, respectively. Albumin efflux from blood to the exsudate correlated with lipoprotein efflux (r = 0.7) in necrotizing
pancreatitis
. The latter suggests that proteins penetrated together the tissue barrier blood/peritoneal space. The less albumin and lipoprotein concentrations in serum, the more they are in the exsudate (r = -0.57 and -0.47, respectively); probably, their concentration decrease in blood is due to to their efflux into the exsudate.

The aim of this study was to assess the predictability of the outcome of acute pancreatitis using the Ranson, Glascow, and Acute Physiology and Chronic Health Evaluation (APACHE) II scores, the computed tomography (CT) scan, and several serum markers. Altogether, 137 consecutive patients with acute pancreatitis confirmed by CT scan were prospectively included. Blood samples were obtained daily for 6 days. The predictive value of each parameter was studied by univariate and multivariate analyses comparing mild and severe
pancreatitis
. A total of 111 attacks were graded as mild (81%) and 26 as severe (19%). Ranson (p = 0.3) and APACHE II (p = 0.049) scores appeared insufficiently predictive in the univariate analysis. Pancreatic imaging by CT scan was insufficiently predictive (p > 0.05), whereas the presence of extrapancreatic fluid collections was more indicative of outcome (p <0.05). With the univariate analysis, the four most reliable serum markers were pancreatic amylase (p <0.001), neutrophil elastase (p <0.05), albumin (p <0.002), and C-reactive protein (p <0.001). Results became homogeneous when the CT results were added;
serum albumin
plus extrapancreatic fluid collections (negative predictive value 92%-96% and positive predictive value 67%-100%) comprised the best indicator of severity. None of the parameters tested achieved sufficient predictability when used alone.
Serum albumin
plus extrapancreatic fluid collections comprise the best indicator of severity at the time of admission.

We report a case of blackwater fever with brown plasma due to the presence of methemalbumin. The discovery of plasma with this color is a rare event at the laboratory. This compound appears during intravascular hemolysis or hemorrhagic
pancreatitis
when the ability of haptoglobin and hemopexin to bind free hemoglobin has been exceeded. In these cases some of heme is oxidized to hematin and taken up by
serum albumin
to form an albumin-hematin complex called methemalbumin. The major clinical problem is to evoke the diagnosis of methemalbuminemia and not confuse with methemoglobinemia. In our case, methemalbumin was detected and quantified using a scanning spectrophotometer. Its diagnostic and clinicals consequences are discussed.
