From January 1982 to September 1987, ten diagnosed cases of biliary ascariasis were collected among 8,160 cases who were admitted for biliary tract diseases in our hospital. It represented an incidence of 0.12% in our hospital. In our series, the patients' ages ranged from 33 to 68 years old, with a female predominances. The clinical impression on admission were those of biliary tract stone, infection or pancreatitis. Signs and symptoms of biliary ascariasis were abdominal pain, fever, jaundice, vomiting of round worms and distended gallbladder. Laboratory findings disclosed leukocytosis, mildly elevated alkaline phosphatase, transaminase and bilirubin. There was a relatively high incidence of positive bile culture for bacteria. The reliable diagnostic tools for biliary ascariasis were abdominal real-time ultrasonography and endoscopic retrograde cholangiopancreatography (ERCP). They yielded a diagnostic rate of 40% and 87.5% respectively in our series. The principles of management of biliary ascariasis were conservative treatments including intravenous fluids, nasogastric decompression, antibiotics and antihelmintic agents. Other treatments that were also tried included endoscopic removal of round worms through a T-tube, or nasobiliary drainage. Surgery was considered when there were signs of complications, such as uncontrolled sepsis or suppurative cholangitis. The prognosis of biliary ascariasis was good if patients were diagnosed and treated properly. Regular follow-up with antihelmintic agents is also recommended to avoid reinfection.

Tissue injury is a common occurrence in multiple organ failure, a possible clinical complication of Gram-negative bacterial sepsis. Gram-negative bacteria, in part through lipopolysaccharide (LPS), tumor necrosis factor, and other cytokines, activate neutrophils to increase oxygen consumption and produce reactive oxygen species (ROS). ROS have been suggested to play a critical role in the pathogenesis of multiple organ failure. Accordingly, we hypothesized that the susceptibility of tissues to ROS can be reduced by augmenting the antioxidant status of the affected tissues. Rats were challenged intravenously with LPS (Escherichia coli: 0111:B4) at a dose of 1 mg/kg body weight, and 0, 2, 4, or 6 h later were treated intravenously with plain liposomes or alpha-tocopherol liposomes (20 mg alpha-tocopherol/kg body weight); treated rats were then killed 24 h after LPS challenge. Animals challenged with LPS were extensively damaged in the liver, as evidenced by an increase in plasma alanine aminotransferase and aspartate aminotransferase activities, and also in the lung, as indicated by a decrease in pulmonary angiotensin-converting enzyme and alkaline phosphatase activities. The injection of LPS also resulted in increased myeloperoxidase activities in the two organs, suggestive of activation of the inflammatory response. Within the pulmonary and hepatic organs of LPS-challenged animals, the involvement of oxidative stress mechanisms was evident, because a significant decrease in reduced glutathione and an increase in lipid peroxidation were observed. In contrast, the administration of alpha-tocopherol liposomes in the post-LPS-challenge period resulted in a significant alleviation of both lung and liver injuries, evidenced by a general reversal of the altered biochemical indices toward normal among treated animals. The therapeutic effect was found to be greater when liposomal alpha-tocopherol treatment was given earlier during the development of injury. Plain liposomes administered immediately after LPS injection also protected hepatic and pulmonary tissues from injuries. However, unlike alpha-tocopherol liposomes, plain liposomes did not confer any beneficial effect when administered at later timepoints post-LPS injection. These data suggest that alpha-tocopherol, administered in a liposomal form, may serve as a potentially effective pharmacological agent in the treatment of LPS-induced tissue injuries.

The main complications of endoscopic retrograde cholangiography and sphincterotomy are bleeding, pancreatitis, perforation and sepsis. Two cases of unexplained prolonged cholestatic jaundice in patients who underwent endoscopic retrograde cholangiography (ERC) for biliary obstruction due to choledocholithiasis are reported. The patients were admitted because of right upper quadrant pain, vomiting and jaundice. Laboratory tests showed increased levels of total and conjugated serum bilirubin and increased alkaline phosphatase. Ultrasound examination showed cholelithiasis and choledocholithiasis with bile duct dilatation. ERC with sphincterotomy was performed and gallstones obstructing the common bile duct were removed endoscopically. Following ERC and despite complete patency of the biliary tree, a progressive increase of total and conjugated bilirubin and of alkaline phosphatase was noted, associated with itching and total stool discoloration. The insertion of nasobiliary drain did not improve the jaundice. Prednisolone treatment for 12 days was associated with progressive restoration of serum bilirubin alkaline phosphatase to normal levels. It was postulated that the radiocontrast material used may have acted toxically on the liver with disruption of the canalicular plasma membrane. It is proposed that intrahepatic cholestasis should be added in the list of complications of endoscopic retrograde cholangiography.

Peripheral stem cells were mobilized and collected in 20 children with stage 4 neuroblastoma. A total of 37 leukaphereses were performed in the 20 patients. The mean number of collected cells was 5.6 +/- 2.4 x 10(8)/kg (range 1.9-10.5), and the number of collected CD34+ progenitors was 6.1 +/- 6.3 x 10(6)/kg (range 0.75-21.7). CD34-positive selection was performed using the CellPro method. Of the adsorbed cells, 42 +/- 20% (range 4.3-76.6) stained positively for CD34, and the number of positively selected CD34+ cells was 2.0 +/- 1.9 x 10(6)/kg (range 0.09-7.1). The mean recovery of CD34+ cells was 36 +/- 20% (range 6-67). For detection of contaminating neuroblastoma cells before and after CD34-positive selection, a murine antidisialoganglioside GD2 antibody (14.G2a) was used, followed by the alkaline phosphatase antialkaline phosphatase (APAAP) method. Before the positive selection, various numbers of contaminating neuroblastoma cells were found in the leukaphereses of 7 patients. After positive selection, neuroblastoma cells were still detectable in all 7 patients, with a mean log depletion of tumor cells of 1.41 +/- 0.45 (range 0.69-2.13). In 1 patient, contaminating neuroblastoma cells were found only after CD34-positive selection. In 15 of the 20 patients, high-dose chemotherapy was performed, and positively selected CD34+ cells were reinfused in 12 patients. In 10 of these, the mean time to reach > 0.5 x 10(9)/L granulocytes was 12.3 +/- 1.7 days (range 10-16). One patient died at day 7 due to sepsis, and in 1 patient the backup was given at day 15. Because of the low number of collected CD34+ cells, 3 patients were grafted with a combination of unmanipulated PBSC and CD34+ progenitors. In summary, we have shown that positive selection of peripheral CD34+ progenitors is feasible in pediatric patients. However, strategies to improve the recovery of the CD34+ cells and the purging efficacy of this method (i.e., higher enrichment of CD34+ cells, combination of positive and negative selection methods) should be evaluated further.

As with most liver diseases, the symptoms of hepatitis in dogs are nearly always aspecific: the dogs eat less, are apathetic, sometimes have polyuria/polydipsia, and sometimes have diarrhoea. Hepatoencephalopathy and ascites only occur with these symptoms in very advanced stages of chronic hepatitis. Only a part of the dogs have jaundice. Because of these aspecific symptoms, the diagnosis hepatitis is often not taken into consideration, even though the presence of a liver disease can be easily detected by measuring plasma concentrations of alkaline phosphatase and bile acids, one or both of which are elevated. The diagnosis is confirmed by histological examination of a liver biopsy sample. The most common forms of hepatitis are non-specific reactive hepatitis, acute hepatitis, and chronic hepatitis. Non-specific reactive hepatitis is a reaction against endotoxin as a result of sepsis or an increased gastrointestinal absorption. Treatment is directed to the primary process. Leptospirosis also causes non-specific reactive hepatitis, but then renal insufficiency is the most prominent feature. The diagnosis is made not on the basis of a liver biopsy but on the basis of increased IgM titres against Leptospira. Immediate treatment with antibiotics and infusions at the first signs (jaundice and uraemia) can save the animal's life. Acute hepatitis can develop as a result of infection, toxins, or liver hypoxia. There is no specific treatment, but adequate recovery often occurs with supportive treatment. Corticosteroids are contraindicated. Chronic hepatitis, which can lead to cirrhosis, is the most common form of hepatitis. It is an autoimmune inflammatory reaction that is usually caused by a virus infection but sometimes by poisoning (intoxication). Long treatment with prednisolone or azathioprine is usually successful, but early recognition of the disease increases the likelihood of success. Nowadays, chronic hepatitis due to hepatic copper accumulation in Beddlington terriers can be detected by DNA tests. Such tests make it possible to distinguish between carriers and non-carriers. Affected animals can be kept symptom-free by life-long treatment with zinc gluconate or penicillamine.

A 52-year-old female underwent autologous BMT because of acute myeloid leukaemia FAB M4 in second remission. Since the patient had no HLA-identical sibling she received a purged autologous BM transplant. On day +5 she developed signs of a sepsis syndrome with fluid retention and was treated with broad-spectrum antibiotic therapy. However, her body weight remained high, ascites and an increase of total serum bilirubin and alkaline phosphatase developed. The icterus worsened to a total bilirubin level of 25 mg/100 ml. Sonographic and endoscopic imaging showed a dilated gall bladder but disclosed a post-hepatic cause for the icterus. A transjugular liver biopsy on day +71 revealed severe cholestasis and siderosis. The patient remained aplastic with constantly increased bilirubin levels. On day +73 septic shock syndrome occurred and the patient died of multiorgan failure 3 days later. At autopsy, a highly differentiated bile duct adenocarcinoma at the porta hepatis, so-called Klatskin tumour, was found, explaining the fatal course with intractable cholestasis.

We determined the diseases associated with extremely high levels of alkaline phosphatase in hospitalized patients. Computerized laboratory records of the Hospital of Saint Raphael identified all inpatients who had elevations of alkaline phosphatase above 1,000 U/l from April 1994 to September 1995. Thirty-seven inpatients with alkaline phosphatase levels above 1,000 U/l were identified. Six had bone involvement from malignancy or Paget's disease and were eliminated from further analysis, and 31 patients were included in the study. Levels of alkaline phosphatase ranged from 1,014 to 3,360 U/l. Ten patients had sepsis as the cause of the elevated alkaline phosphatase. These included gram-negative organisms, gram-positive organisms, and two patients with fungal sepsis. Seven of 10 patients with sepsis had an extremely high alkaline phosphatase level and a normal bilirubin, 3 of 10 patients with sepsis also had acquired immunodeficiency syndrome (AIDS). Eight patients had biliary obstruction, 7 with malignant obstruction and 1 with a common bile duct stone. Nine patients had AIDS. The cause of the elevated alkaline phosphatase in these included three with sepsis, three with mycobacterium avium intracellulare (MAI) infection, two with cytomegalovirus infection, and one with Dilantin toxicity. Three patients had diffuse liver metastases. Finally, four patients had benign intrahepatic disease, including one patient with liver hemangiomas, one patient with sarcoid hepatitis, one patient with lead toxicity, and one patient with drug-induced cholestasis. Extremely high elevations of alkaline phosphatase are most frequently seen in patients with sepsis, malignant obstruction, and AIDS. Patients with sepsis can have an extremely high alkaline phosphatase level and a normal bilirubin. A variety of other causes were also noted.

A 78-year-old man was diagnosed as leukocytosis in February 1994. Physical examination revealed marked hepatosplenomegaly. A peripheral blood examination disclosed 95,090/microliter leukocytes without hiatus leukemicus, 6.5 g/dl Hb, and 15.0 x 10(4)/microliter platelets. The neutrophil alkaline phosphatase score was 27, and serum VB12 was above 1,600pg/ml. IgG was identified as monoclonal immunoglobulin of type lambda. Bone marrow specimens demonstrated marked granulocytic hyperplasia. Neither the Philadelphia chromosome (Ph1) nor BCR gene rearrangement was detected; hence, the diagnosis of Ph1 (-) chronic myeloid leukemia (CML) was made. The patient was treated with hydroxyurea and low-dose VP-16 with no improvement, and died of pneumonia and sepsis in June 1995. This case was considered to be consistent with atypical CML (aCML) according to the FAB classification because monocytosis was not observed. It seems likely and interesting that the coexistent monoclonal gammopathy and aCML might have arisen from common abnormal hematopoietic stem cells.

Group B Streptococcus (GBS) is the leading cause of bacterial sepsis and meningitis among neonates. While the capsular polysaccharide (CPS) is an important virulence factor of GBS, other cell surface components, such as C proteins, may also play a role in GBS disease. CPS production by GBS type III strain M781 was greater when cells were held at a fast (1.4-h mass-doubling time [td]) than at a slow (11-h td) rate of growth. To further investigate growth rate regulation of CPS production and to investigate production of other cell components, different serotypes and strains of GBS were grown in continuous culture in a semidefined and a complex medium. Samples were obtained after at least five generations at the selected growth rate. Cells and cell-free supernatants were processed immediately, and results from all assays were normalized for cell dry weight. All serotypes (Ia, Ib, and III) and strains (one or two strains per serotype) tested produced at least 3.6-fold more CPS at a td of 1. 4 h than at a td of 11 h. Production of beta C protein by GBS type Ia strain A909 and type Ib strain H36B was also shown to increase at least 5.5-fold with increased growth rate (production at a td of 1. 4 h versus 11 h). The production of alpha C protein by the same strains did not significantly change with increased growth rate. The effect of growth rate on other cell components was also investigated. Production of group B antigen did not change with growth rate, while alkaline phosphatase decreased with increased growth rate. Both CAMP factor and beta-hemolysin production increased fourfold with increased growth rate. Growth rate regulation is specific for select cell components in GBS, including beta C protein, alkaline phosphatase, beta-hemolysin, and CPS production.

The purpose of this study was to examine the effect of endogenous somatostatin hormone on bacterial translocation in obstructive jaundiced rats. Five groups of rats were studied: group I (n = 10), non-operated group (control); group II (n = 10), sham-operated group which underwent laparotomy and dissection of portal elements, while the common bile duct was not ligated and somatostatin was not injected; group III (n = 10), same as group II, plus injection of somatostatin; group IV (n = 10), common bile duct was ligated with laparotomy but somatostatin was not injected; group V (n = 10), same as group IV, plus somatostatin injection. The blood was analyzed for somatostatin, alkaline phosphatase, and bilirubin levels on the third and tenth days in all animals. At study termination (tenth day), peritoneal swab and blood cultures were taken, and liver, spleen, lung, and mesenteric lymph nodes were harvested for microbiological studies. Bacterial translocation levels were higher in groups III, IV, and V when compared with levels in groups I and II. Similar translocation levels were obtained when blood somatostatin levels were comparable. However, the highest translocation rate was found in groups IV and V in which the blood somatostatin level was also higher when compared with that in other groups. This finding shows that blood somatostatin level is increased in obstructive jaundice. This may explain the bacterial translocation and related sepsis found in obstructive jaundice.
