RESUMEN

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is often difficult to diagnose because bacteria in ascites cannot be detected accurately by conventional culture. In situ hybridization (ISH) was previously developed for rapid detection of genes from bacteria phagocytized by neutrophils. SBP may develop after bacteria enter into the systemic circulation following bacterial translocation. Therefore, we performed ISH to identify bacteria in blood samples collected from patients with decompensated liver cirrhosis (LC). METHODS: In this retrospective study, peripheral blood samples were collected from 60 patients with decompensated LC, and bacteria were detected by both blood culture and ISH. Moreover, 35 patients underwent paracentesis for diagnosis of SBP. RESULTS: Eight of 35 patients were diagnosed with SBP by polymorphonuclear neutrophil counts, and one patient was diagnosed with bacterascites. Seven of the nine patients showed positive results for ISH, whereas bacteria were detected in only two cases by blood culture. Thirty-seven of 60 cases (62%) showed positive results for ISH, whereas only six samples (10%) were positive by blood culture analysis. Compared with the 23 cases of negative ISH, the 37 cases of positive ISH showed a higher frequency of fever, higher Child-Pugh scores, and lower albumin levels. CONCLUSIONS: Detection of bacteria by ISH suggested that bacterial translocation, which cannot be proven by conventional culture, occurred in these patients, and that ISH could be helpful for the early diagnosis of some types of infection and prevention of SBP in these patients.

RESUMEN

AIM: Simeprevir (SMV) is a protease inhibitor which demonstrates good tolerability and high antiviral response in patients with hepatitis C. The clinical outcomes of triple therapy using simeprevir, pegylated interferon and ribavirin (SMV/PEG IFN/RBV) for recurrent hepatitis C after living donor liver transplantation (LDLT) have not been well reported. In this study, we assessed the outcomes of patients with recurrent hepatitis C (genotype 1) after LDLT who received triple therapy at our hospital. METHODS: SMV/PEG IFN/RBV was administrated for 12 weeks (triple therapy), followed by another 12 weeks or extended period of PEG IFN/RBV (dual therapy). Virological response, interaction with calcineurin inhibitors and adverse events were retrospectively analyzed. RESULTS: Ten patients with recurrent hepatitis C after LDLT completed 12 weeks of triple therapy. Nine patients achieved rapid or early virological response, and one patient was a non-responder. The nine responders received subsequent dual therapy, and the duration of dual therapy was extended (24 to 36 weeks) in five cases. Although one patient was in relapse 8 weeks after completing the standard duration (12 weeks) of dual therapy, eight patients achieved sustained virological response for 12 weeks (SVR12). The SVR12 rate was 80%. Trough levels of calcineurin inhibitor did not show marked changes after introduction of SMV in all cases. There were no major adverse events associated with SMV. CONCLUSION: SMV treatment may be a safe and effective option for recurrent hepatitis C after LDLT.

RESUMEN

Along with the development of interferon and therapeutic medication, the incidence of viral hepatitis constituting the largest part of liver disease decreased, and the main target in the field of liver disease is now shifting from viral hepatitis to alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) as metabolic liver disease. Although these diseases tend.to. be gathered as non-viral liver disease because the similar specific liver tissue, the natural history and etiology are considerably different between them. We need to distinguish both of them to do appropriate treatment intervention. Questioning of amount of drinking is needed, but we experience some difficult cases to understand drinking history because of a too little declaration of amount of drinking. A new ultrasonic image analyses using propagation speed in the organization of the pulse vibration wave was developed as Fibroscan by Echosens company in recent years. Fibroscan is a non-invasive test to quantify liver fibrosis as Liver Stiffness Measurement (LSM). It also detects and quantifies steatosis simultaneously using the Controlled Attenuation Parameter (CAP). CAP is a measurement of the ultrasound attenuation. We measured liver steatosis of patients using Fibroscan, and other blood tests. 63 cases of ALD, 177 cases of NAFLD, 57 cases of Virus and 271 cases of Normal were enrolled. CAP value were significantly lower in the ALD group compared with NAFLD group. (P < 0.0053, ALD 268 dB/m : NAFLD 290 dB/m) We elucidate the diagnostic accuracy of CAP using Fibroscan for ALD patients, comparing the results of them to those of virus patients and NAFLD patients.

RESUMEN

The Intractable Liver Diseases Study Group of Japan, supported by the Ministry of Health, Labor and Welfare, established novel diagnostic criteria for "acute liver failure" in 2011. In these criteria, patients without histological findings of hepatitis are included in the disease entity of "acute liver failure", as in Europe and the USA. In this report, classification criteria for the etiologies of "acute liver failure" in Japan are proposed.

RESUMEN

Glucagon-like peptide-1 (GLP-1) promotes insulin release; however, the relationship between the GLP-1 signal and chronic pancreatitis is not well understood. Here we focus on chemokine (C-C motif) ligand 2 (CCL2) and its receptor (CCR2) axis, which regulates various immune cells, including macrophages, to clarify the mechanism of GLP-1-mediated insulin secretion in chronic pancreatitis in mice. One and multiple series of repetitive cerulein administrations were used to induce acute and chronic cerulein pancreatitis, respectively. Acute cerulein-administered CCR2-knockout (KO) mice showed suppressed infiltration of CD11b(+)Gr-1(low) macrophages and pancreatic inflammation and significantly upregulated insulin secretion compared with paired wild-type (WT) mice. However, chronic cerulein-administered CCR2-KO mice showed significantly increased infiltration of CD11b(+)/Gr-1(-) and CD11b(+)/Gr-1(high) cells, but not CD11b(+)/Gr-1(low) cells, in pancreas with severe inflammation and significantly decreased insulin secretion compared with their WT counterparts. Furthermore, although serum GLP-1 levels in chronic cerulein-administered WT and CCR2-KO mice were comparably upregulated after cerulein administrations, GLP-1 receptor levels in pancreases of chronic cerulein-administered CCR2-KO mice were significantly lower than in paired WT mice. Nevertheless, a significantly higher hyperglycemia level in chronic cerulein-administered CCR2-KO mice was markedly restored by treatment with a GLP-1 analog to a level comparable to the paired WT mice. Collectively, the CCR2/CCL2 axis-mediated CD11b(+)-cell migration to the pancreas is critically involved in chronic pancreatitis-mediated hyperglycemia through the modulation of GLP-1 receptor expression and insulin secretion.

RESUMEN

BACKGROUND & AIMS: Acute pancreatitis is a common inflammatory disease mediated by damage to acinar cells and subsequent pancreatic inflammation with recruitment of leukocytes. We investigated the pathologic roles of innate immune cells, especially macrophages, in cerulein- and L-arginine-induced acute pancreatitis in mice. METHODS: Acute pancreatitis was induced by sequential peritoneal administration of cerulein to mice. We determined serum concentrations of amylase and lipase, pancreatic pathology, and features of infiltrating mononuclear cells. We performed parabiosis surgery to assess the hemodynamics of pancreatic macrophages. RESULTS: Almost all types of immune cells, except for CD11b(high)CD11c(-) cells, were detected in the pancreas of healthy mice. However, activated CD11b(high)CD11c(-) cells, including Gr-1(low) macrophages and Gr-1(high) cells (granulocytes and myeloid-derived suppressor cells), were detected in damaged pancreas after cerulein administration. CCL2(-/-) mice given cerulein injections developed significantly less severe pancreatitis, with less infiltration of CD11b(high)CD11c(-)Gr-1(low) macrophages, but comparable infiltration of myeloid-derived suppressor cells, compared with cerulein-injected wild-type mice. Parabiosis and bone marrow analyses of these mice revealed that the CD11b(high)CD11c(-)Gr-1(low) macrophages had moved out of the bone marrow. Furthermore, mice with macrophage-specific deletion of suppressor of cytokine signaling 3 given injections of cerulein developed less severe pancreatitis and Gr-1(low) macrophage produced less tumor necrosis factor-α than wild-type mice given cerulein, although the absolute number of CD11b(high)CD11c(-)Gr-1(low) macrophages was comparable between strains. Induction of acute pancreatitis by L-arginine required induction of macrophage migration by CCL2, via the receptor CCR2. CONCLUSIONS: Cerulein induction of pancreatitis in mice involves migration of CD11b(high)CD11c(-)Gr-1(low) macrophage from the bone marrow (mediated by CCL2 via CCR2) and suppressor of cytokine signaling 3-dependent activation of macrophage. These findings might lead to new therapeutic strategies for acute pancreatitis.

RESUMEN

AIM: To summarize the annual nationwide survey on fulminant hepatitis (FH) and late-onset hepatic failure (LOHF) between 2004 and 2009 in Japan. METHODS: The annual survey was performed in a two-step questionnaire process to detail the clinical profile and prognosis of patients in special hospitals. RESULTS: Four hundred and sixty (n = 227 acute type; n = 233 subacute type) patients had FH and 28 patients had LOHF. The mean age of patients with FH and LOHF were 51.1 ± 17.0 and 58.0 ± 14.4 years, respectively. The causes of FH were hepatitis A virus in 3.0%, hepatitis B virus (HBV) in 40.2%, other viruses in 2.0%, autoimmune hepatitis in 8.3%, drug allergy-induced in 14.6% and indeterminate etiology in 29.6% of patients. HBV reactivation due to immunosuppressive therapy was observed in 6.8% of FH patients. The short-term survival rates of patients without liver transplantation (LT) were 48.7% and 24.2% for the acute and subacute type, respectively, and 13.0% for LOHF. The prognosis was poor in patients with HBV reactivation. The implementation rate for LT in FH patients was equivalent to that in the previous survey. The short-term survival rates of total patients, including LT patients, were 54.2% and 40.8% for the acute and subacute type, respectively, and 28.6% for LOHF. CONCLUSION: The demographic features and etiology of FH patients has gradually changed. HBV reactivation due to immunosuppressive therapy is problematic. Despite advances in therapeutic approaches, the prognosis of patients without LT has not improved.

RESUMEN

A 64-year-old male presented with discomfort in the chest. His endoscopic examination and CT scan showed esophageal cancer with multiple liver metastases. A total of ten courses of systemic chemotherapy by 5-fluorouracil (5-FU) (800 mg for five days) and cisplatin (CDDP) (80 mg/day on the first day of the week for four weeks) were performed, and liver and lymph node metastases disappeared. The primary lesion was the only site detected positive by PET scan. After a concurrent chemoradiation therapy, salvage endoscopic mucosal resection (EMR) was performed on the remainder of the primary site and the patient gained a complete response (CR). We report this case because, although the mean survival time of advanced esophageal cancer is less than one year, this patient responded to chemotherapy and gained complete response by salvage EMR. This patient has had no recurrence for four years since his initial diagnosis.

RESUMEN

We have explored the pathological role of the MyD88 signaling pathway via Toll-like receptors (TLRs) that mediate the recognition of pathogen-associated molecular patterns (PAMPs) in a murine model of autoimmune hepatitis induced by administering Concanavalin A (ConA). We first found that various TLRs and MyD88 molecules were expressed in liver of Con A-treated and untreated wild-type (WT) mice including liver macrophages. Flowcytometric analysis revealed that liver CD11b(+)CD11c(-) and CD11b(+)CD11c(+) antigen-presenting cells express TLR2, although NK and NKT cells did not. When WT and MyD88(-/-) mice were intravenously administered with Con A, the severity of hepatitis was significantly lower in Con A-injected MyD88(-/-) mice than in WT mice in terms of the histopathology, the levels of serum transaminase and pro-inflammatory cytokines (TNF-alpha, IFN-gamma, and IL-6), and upregulation of CD80/CD86 and TNF-alpha on/in liver macrophages. The results provide evidence of a possible contribution of the TLRs-MyD88 signaling pathway in activating TLR-expressing liver macrophages in the autoimmune hepatitis model, and thus indicate that the strategy of blockade of pathological pathogens via the intestinal lumen may be feasible for the treatment of the disease.

RESUMEN

BACKGROUND/AIMS: King's College Hospital (KCH) criteria and the model for end-stage liver disease (MELD) score are useful and widely-employed prognostic markers for acute liver failure (ALF). We previously reported that liver atrophy is an important prognostic factor for ALF. The aim of the present study was to assess the value of liver volumetry and to generate a new prognostic formula. METHODS: Computed tomography-derived liver volume (CTLV) and standardized liver volume (SLV) of 30 adult ALF patients were calculated at the time of diagnosis. Patients were assigned to one of two groups: group A consisted of 13 patients who recovered without surgical intervention, and group B consisted of 17 patients who died due to liver failure or who underwent living donor liver transplantation (LDLT). RESULTS: The median CTLV/SLV ratios of groups A and B were 1.019 and 0.757, respectively (P = 0.0009). The difference was most significant (P = 0.0002) at the probability cutoff point of 0.80 for CTLV/SLV ratio; the sensitivity and specificity were 76.5% and 92.3%, respectively. Serum total bilirubin (TB) levels and CTLV/SLV ratio were selected as independent prognostic factors by multivariate analysis. A prognostic formula including volumetric analysis was established: Z = -2.3813 - [0.15234 x TB (mg/dl)] + [4.5734 x CTLV/SLV] (AUC = 0.87783, P = 0.0002). CONCLUSIONS: The CTLV/SLV ratio is a very useful marker for predicting the prognosis of adult ALF. Our prognostic formula including only the CTLV/SLV ratio and TB is simple and useful and awaits validation in a future larger-scale prospective study.

RESUMEN

AIM: We investigated lipid metabolism in patients with chronic hepatitis C virus (HCV), serotype 1, undergoing combination therapy with PEG-IFN alpha-2b (PEG-IFN) and ribavirin (RBV). METHODS: A total of 185 patients with chronic HCV (HCV serotype 1; HCV RNA levels >/= 100 KIU/mL) who received a combination of PEG-IFN and RBV were enrolled. RESULTS: Sustained virological response (SVR) was obtained in 82 cases (44.3%). The median age, red blood cell and platelet counts differed significantly between the SVR and non-SVR groups before treatment. However there was no significant difference between total cholesterol (TC), LDL-cholesterol (LDL-C) and triglyceride (TG) levels before treatment. TC and LDL-C levels decreased during the treatment in both groups. In the SVR group, TC and LDL-C levels increased quickly after the end of the treatment and were higher than those before treatment. On the other hand, TC and LDL-C levels returned to pretreatment levels in the non-SVR group and were significantly lower than in the SVR group. TG levels were elevated in both groups after the beginning of treatment. After the end of treatment, this elevation persisted in the SVR group, while TG levels returned to pre-treatment levels in the non-SVR group. There was a significant difference in TG levels at 24 weeks after the end of the treatment between the 2 groups. In the non-SVR group some patients achieved normalization of ALT (alanine aminotransferase) but persistence of normal ALT levels did not contribute to the increase of TC and TG. CONCLUSION: TC, LDL-C and TG levels increase only in patients with HCV, serotype 1, undergoing combination therapy when a SVR is achieved.

RESUMEN

Recently prevalence of alcoholic liver disease has been increasing in Japan associated with an increase in alcoholic beverage consumption. In the present study, we addressed the recent trend in the etiology of liver cirrhosis (LC) in Japan, and investigated the influence of habitual drinking and viral hepatitis type C in the progression of LC. We carried out nation-wide survey by asking for the hospitals that are approved by the Japanese Society of Gastroenterology for the etiology of in-patients with LC, and compared to that in our hospital. Regarding the cases in nation-wide survey, 1274 cases (14%) of 9126 patients with LC were pure (without any markers of hepatitis virus) heavy drinkers, and 580 cases (6%) were heavy drinkers with any markers of hepatitis virus. However, in our general hospital, 24 cases of 101 patients with LC (24%) were pure heavy drinker, and 31 cases (30%) were heavy drinkers with any markers of hepatitis virus. In conclusion, although influence of hepatitis virus infection in alcoholic LC has been decreasing, it still plays an important role in the progression of alcoholic LC, especially in the general hospitals. Education of abstinence or low risk drinking is important not only heavy drinkers but also habitual drinkers with hepatitis virus infection.

RESUMEN

AIM: The objective of this study was to determine whether Cardiotopic Pills (CP) affects fatty liver in rats fed ethanol chronically. MATERIALS AND METHODS: Male Wistar rats were treated with liquid diet that contained ethanol (36% of total calories) or an isocaloric carbohydrate instead of ethanol for 6 weeks. CP, an oral herbal medicine including Danshen (Salviae Miltiorrhiza), Panax notoginseny and Dyroblanops aromatica gaertn, have been clinically used for vascular diseases such as coronary diseases and cerebral infarction. CP was administered orally with the liquid diets for 2 weeks 0.4 mg/kg body weight/day with the liquid diet thereafter. Serum triglyceride and total cholesterol levels, total protein, albumin, and AST and ALT activities are measured. Histological examination was also carried out. In another set of experiments, autofluorescence of NAD(P)H, an indicator of mitochondrial O2 consumption and redox status, was measured by an intravital microscopy, and peroxisome proliferators-activated receptor-(PPAR)-alpha and gamma mRNA levels were evaluated by real time quantitative PCR methods. RESULTS: Chronic ethanol consumption elevated serum triglyceride level, and caused fatty degeneration of liver. After administration of CP, fatty degeneration was not observed in rats fed ethanol chronically. Elevation of serum triglyceride level was not noted after treatment with CP (Ethanol: 79.4 +/- 9.3 mg/dl, Ethanol+CP: 48.0 +/- 4.4, respectively, p<0.05). CP did not affect any other laboratory data or NAD(P)H levels. Chronic ethanol consumption did not affect PPAR-gamma mRNA levels, while it decreased PPAR-alpha mRNA levels in the liver. CP prevented the ethanol-induced decrease in PPAR-alpha mRNA levels. CP and its components could enhance expression of PPAR-alpha mRNA levels. CONCLUSION: These results suggest that CP may be useful to prevent alcoholic fatty liver via enhanced expression of PPAR-alpha.

RESUMEN

OBJECTIVE: In this study, we evaluated the performance of a newly commercialized small-animal positron emission tomography (PET) scanner, ClairvivoPET, which provides significant advantages in spatial resolution, sensitivity, and quantitative accuracy. METHODS: This scanner consists of depth of interaction detector modules with a large axial extent of 151 mm and an external (137)Cs source for attenuation correction. Physical performances, resolution, sensitivity, scatter fraction (SF), counting rate including noise equivalent count (NEC) rate, quantitative accuracy versus activity strength, and transmission accuracy, were measured and evaluated. Animal studies were also performed. RESULTS: Transaxial spatial resolution, measured with a capillary tube, was 1.54 mm at the center and 2.93 mm at a radial offset of 40 mm. The absolute sensitivity was 8.2% at the center, and SFs for mouse-and rat-sized phantoms were 10.7% and 24.2%, respectively. Peak NEC rates for mouse-and rat-sized uniform cylindrical phantoms were 328 kcps at 173 kBq/ml and 119 kcps at 49 kBq/ml, respectively. The quantitative stability of emission counts against activity strength was within 2% over 5 half-lives, ranging from 0.6 MBq to 30 MBq. Transmission measurement based on segmented attenuation correction allowed 6-min and 10-min scans for mouse-and rat-sized cylindrical phantoms, respectively. Rat imaging injected with (18)F-NaF resulted in visibility of fine bone structures, and mouse imaging injected with (18)F-D-fluoromethyl tyrosine demonstrated the feasibility of using this system to obtain simultaneous time activity curves from separate regions, such as for the heart and tumors. CONCLUSIONS: ClairvivoPET is well suited to quantitative imaging even with short scan times, and will provide a number of advantages in new drug development and for kinetic measurement in molecular imaging.

RESUMEN

A 40-year-old man, who had suffered from general malaise and brown urine during his stay in China, was admitted with remarkable jaundice and hepatocellular disorders soon after he returned to Japan. Because his coagulation test results worsened, he was transferred to our hospital. No evidence of hepatitis A-D virus infection, autoimmune hepatitis, or metabolic disorders was noticed. His prothrombin time was extended (18%), grade II encephalopathy appeared on the second hospital day, and fulminant hepatitis was diagnosed. Artificial liver support was introduced, and his hepatic coma and coagulation parameters gradually recovered. Genotype IV hepatitis E virus RNA was detected in his early phase sera and also both IgG and IgM type anti-hepatitis E virus antibodies were detected. Fulminant hepatitis E resulting from infection in China was diagnosed.

RESUMEN

OBJECTIVE: The aim of this study is to assess the effectiveness of continuous regional arterial infusion (CRAI) of protease inhibitors in patients with severe acute pancreatitis (SAP) including acute necrotizing pancreatitis. METHODS: This retrospective study was conducted among 44 institutions in Japan from 2009 to 2013. Patients 18 years or older diagnosed with SAP according to the criteria of the Japanese Ministry of Health, Labour and Welfare study group (2008) were consecutively enrolled. We evaluated the association between CRAI of protease inhibitors and mortality, incidence of infection, and the need for surgical intervention using multivariable logistic regression analysis. RESULTS: Of 1159 patients admitted, 1097 patients with all required data were included for analysis. Three hundred and seventy-four (34.1%) patients underwent CRAI of protease inhibitors and 723 (65.9%) did not. In multivariable analysis, CRAI of protease inhibitors was not associated with a reduction in mortality, infection rate, or need for surgical intervention (odds ratio [OR] 0.79, 95% confidence interval [CI] 0.47-1.32, P = 0.36; OR 0.97, 95% CI 0.61-1.54, P = 0.89; OR 0.76, 95% CI 0.50-1.15, P = 0.19; respectively). CONCLUSIONS: Continuous regional arterial infusion of protease inhibitors was not efficacious in the treatment of patients with SAP.

RESUMEN

Recently incidence of alcoholic liver disease (ALD) has been increasing in Japan associated with an increase in alcoholic beverage consumption. There have been a large number of reports about the relationship between alcohol and hepatocarcinogenesis, but it remains controversial. In the present study, we addressed the recent trend in incidence of ALD including liver cirrhosis (LC), and hepatocellular carcinoma (HCC) in heavy drinkers in Japan. We carried out nation-wide survey by asking for the hospitals that are approved by the Japanese Society of Gastroenterology for recent aspects of in-patients with ALD. Except for HCC, percentage of ALD without viral hepatitis is more than 70%, which is increased when compared to the national survey carried out in 1992. In alcoholic LC patients, those who did not have viral hepatitis were 81%. However, the percentage of HCC without viral hepatitis was 34% of all of the heavy drinkers with HCC. Regarding the case in our university hospital, 138 cases (32%) of 432 patients with HCC were heavy drinkers. However, regarding in our general hospital, 15 cases of 23 patients with HCC (61%) were heavy drinkers. In conclusion, since the consumption of alcohol is increasing in Japan, the frequency and number of cases of alcoholic liver cirrhosis are increasing. Viral hepatitis infection, however, still plays an important role in hepatocarcinogenesis in heavy drinkers.

RESUMEN

The patient was a 50-year-old woman who suffered from gastric discomfort. She was first diagnosed as intrahepatic cholangiocarcinoma with hepatic, paraaortic lymphnodal and bone metastasis. Initial systemic chemotherapy using gemcitabine (GEM) and 5-FU failed to control the disease activity. Then she was given GEM and cisplatin (CDDP) combination chemotherapy. The response was assessed as stable disease (SD), but grade 4 leukopenia was seen. Then systemic therapy using GEM, and hepatic arterial infusion therapy with CDDP, l-leucovorin and 5-FU were continued biweekly. Partial response (PR) was achieved six months later, and her disease status was maintained as SD. This hepatic arterial infusion chemotherapy would be safe and feasible as therapy for inoperable intrahepatic cholangiocarcinoma.

RESUMEN

AIM: Cardiotonic Pill (CP), an oral herbal medicine that includes Danshen (Salviae Miltiorrhizae), Panax notoginseny and Dyroblanops aromatica gaertn, has been clinically used for vascular diseases such as occlusive vasculitis, coronary diseases, atherosclerosis, and cerebral infarction. The main component, Salviae Miltiorrhizae, has been reported to prevent cerebral and intestinal reperfusion injury. However, little is known about the effect of CP on hepatic microcirculation. Thus, this study aimed to determine whether CP could affect hepatic microvascular dysfunction elicited by gut ischemia/reperfusion (I/R) in rats fed ethanol chronically. METHODS: Male Wistar rats were pair-fed with a liquid diet containing ethanol or isocaloric control diet for 6 wk. After laparotomy, one lobe of the liver was examined through an inverted intravital microscope. The rats were exposed to 30 min of gut ischemia followed by 60 min of reperfusion. Rhodamine-6G-labeled leukocytes in the sinusoids were observed 90 min after the onset of superior mesenteric artery occlusion. Plasma tumor necrosis factor (TNF)-alpha and endotoxin levels were measured 1 h after the onset of reperfusion. Plasma alanine aminotransferase (ALT) activities were measured 6 h after the onset of reperfusion. In another set of experiments, CP (0.8 g/kg, intragastrically) was administered 1 and 24 h before the onset of ischemia. RESULTS: In control rats, gut I/R elicited increases in the number of stationary leukocytes, and plasma TNF-alpha and endotoxin levels and plasma ALT activities. These changes were mitigated by pretreatment with CP. In ethanol-fed rats, the gut I/R-induced increases in the number of stationary leukocytes, plasma endotoxin levels and ALT activities were enhanced. Pretreatment with CP attenuated the enhancement of gut I/R-induced responses by chronic ethanol consumption. CONCLUSION: These results suggest that CP prevents the gut I/R-induced hepatic microvascular dysfunction and hepatocellular injury. A reduction of inflammatory responses such as TNF-alpha production via reduction of blood endotoxin levels appears to be involved in the mechanisms. Chronic ethanol consumption enhances gut I/R-induced hepatic microvascular and hepatocellular injury. CP also attenuates an enhancement of gut I/R-induced responses by chronic ethanol consumption via the reduction of blood endotoxin levels.

RESUMEN

Chemotherapies for recurrent gastric cancer have not yet been established. Here we report a case of type 4 gastric cancer associated with lymphangitis carcinomatosis which became refractory to the previous chemotherapies. The case was a 40-year-old woman. She had been diagnosed with gastric cancer after a Krukenberg tumor operation. Chemotherapies (TS-1 plus CDDP as first-line, and TS-1 plus taxanes as second-line) were performed, and a partial response was achieved. Disease activity has been well controlled until this time. Since recurrence of left pleural effusion and lymphangitis carcinomatosis was recognized, we changed the chemotherapy TS-1 plus CPT-11. Pleural effusion decreased and lymphangitis carcinomatosis improved. The serum CA 19-9 level rose transiently after CPT-11 administration, and tended to fall at the second week of chemotherapy. However, the patient died 2 years 4 months after the onset. TS-1 plus CPT-11 combination chemotherapy would be effective for lymphangitis carcinomatosis and also useful as third-line chemotherapy for recurrent gastric cancer.
