Abstract: Fifty -two patients with primary biliary cirrhosis (PBC), 10 of whom were 65 years or older at the time of diagnosis, were investigated by laparo-scopy. Laparoscopic findings in these 10 patients were evaluated and compared with those in younger patients. The 10 cases were composed of nine females and one male, and two had been diagnosed as having symptomatic PBC with skin itching, while the remaining eight had asymptomatic PBC. Two, seven and one case were in Scheuer's stage I, II and III, respectively, and eight had chronic non-suppurative destructive cholangitis (CNSDC) on liver biopsy specimens. The majority of senescent PBC patients had typical findings of the early stage of PBC on the liver surface; mild undulations in nine and reddish patches in eight. The laparoscopic findings in senescent PBC were relatively mild. 相似文献

Background: Low incidence of reversal blood flow at the portal vein has been reported by measurement in larger and extrahepatic blood vessels but not in intrahepatic blood vessels in patients with liver cirrhosis. Moreover, there is little information regarding the incidence of reversal blood on the basis of the cause of liver cirrhosis. The aim of this study was to measure the reversal blood flow in the portal vein including intrahepatic branches in patients with alcoholic and viral cirrhosis.
Methods: The blood flow in the portal vein and existence of portosystemic shunt were studied in 52 and 27 patients with alcoholic and viral cirrhosis, respectively, by Doppler ultrasonography. The parameters of liver function test and the prevalence of ascites and esophageal varices were compared between patients with and without reversal blood flow.
Results: Reversal blood flow at the portal vein was found only in patients with only alcoholic cirrhosis (17 of 52 patients) but not in any patients with viral cirrhosis (0 of 27 patients; p < 0.05). The incidence of portosystemic ascites and red color of esophageal varices was also higher in patients with alcoholic cirrhosis with reversal blood flow in the portal vein compared with patients without reversal blood flow ( p < 0.05).
Conclusions: Reversal blood flow in the portal vein is a characteristic feature of alcoholic cirrhosis. The presence of reversal blood flow indicates severe liver diseases, and this feature may have prognostic importance for patients with alcoholic cirrhosis. 相似文献

Background: Treatment of acute organophosphorus (OP) insecticide poisoning is difficult, with many patients dying despite best care. Pre-clinical studies have shown benefit from salbutamol, possibly due speeding alveolar fluid clearance or reducing bronchoconstriction. In this small pilot dose-response study, we aimed to explore whether addition of nebulized salbutamol to standard care might improve resuscitation.Methods: We performed a single-blind phase II study comparing the effect of two different doses of nebulized salbutamol versus saline placebo, in addition to standard treatment. Primary outcome was oxygen saturations over the first 60?min of resuscitation; secondary outcomes included heart rate, incidence of dysrhythmias, time to ‘atropinization’, atropine dose required, and mortality.Result: Seventy-five patients were randomized to receive 5?mg (Salb5, n?=?25) or 2.5mg (Salb2.5, n?=?25) of salbutamol, or saline placebo (NoSalb, n?=?25), by nebulizer. Oxygen saturations did not differ between groups over the first 60?min of resuscitation (median AUC NoSalb: 1376 [95% CI 1282 to 1470], Salb2.5: 1395 [1305 to 1486], Salb5: 1233 [1100 to 1367]; p?=?.9898). Heart rate was also similar across the three arms. Median time to full atropinization, and atropine dose required, were the same for all three arms (NoSalb 15.0 [10–16] min and 12.6 [8.0–13.4] mg, Salb2.5 15.0 [10–16] min and 12.6 [9.3–16.8] mg, and Salb5 15.0 [10–20] min and 12.6 [10.7–20.6] mg; p?=?.4805 and p?=?.1871, respectively). Three (12%) patients died in the Salb2.5 and Salb5 groups and two (8%) in the NoSalb group.Conclusion: This pilot study, within the limitations of its small size and variation between patients, found no apparent evidence that administration of nebulized salbutamol improved resuscitation of patients with acute OP insecticide self-poisoning. The data obtained provides a basis to design further studies to ultimately test the role of salbutamol in OP insecticide poisoning. 相似文献

Glycyrrhizin enhances interleukin-10 production by liver dendritic cells in mice with hepatitis 总被引:4,自引:0,他引:4
Background Glycyrrhizin (GL), an aqueous extract of licorice root, is known to have various immune-modulating and biological response-modifier activities. GL is used in patients with hepatitis to reduce the activity of liver inflammation; however, the mechanism underlying the anti-inflammatory activity of GL is poorly understood. As antigen-presenting dendritic cells (DC) in the tissue play a major role in the regulation of the inflammatory mucosal milieu during tissue inflammation, we studied whether the function of liver DC was altered by GL therapy in a murine model of concanavalin-A (Con A)-induced hepatitis.Methods Liver DC were propagated from control mice or mice with Con-A-induced hepatitis, and the effect of GL on liver DC was evaluated in vivo and in vitro.Results The levels of interleukin (IL)-10 produced by liver DC were significantly lower in mice with Con-A-induced hepatitis compared with control mice. However, treatment with GL caused increased production of IL-10 in mice with Con A-induced hepatitis. The increased production of IL-10 by mice with Con A-induced hepatitis was also confirmed in vitro by culturing liver DC with GL.Conclusions This study indicates that increased production of IL-10 by liver DC due to GL administration may be involved in downregulation of the levels of liver inflammation in mice with Con A-induced hepatitis. 相似文献

CD163 is a marker of activated macrophages, and increased levels of soluble CD163 have been detected in sera obtained from patients with hepatitis. The aim of this study was to detect the expression of CD163 in the liver from patients with viral hepatitis. Frozen sections of liver specimens were obtained from 5 patients with acute viral hepatitis (AH) and from 23 patients with chronic viral hepatitis (CH). The expression of CD163 in the liver was determined immunohistochemically using monoclonal antibody to human CD163. Double immunostaining was done to assess those cell types that express CD163 in the liver. The frequencies of CD163-positive cells were significantly higher both in the portal areas and in the hepatic lobules in the liver of patients with AH compared to those with CH (p < 0.05). Double immunostaining revealed that most of the CD163-positive cells were macrophages and Kupffer cells, because they expressed CD68. The expression of CD163 was very low in endothelial cells and liver stellate cells. This study shows that macrophages are activated in hepatitis liver. 相似文献

Significant impairments of several aspects of immunity have been described in acute and chronic nutritional deficiencies; however, there have been few studies on antigen-presenting cells during starvation. We examined the antigen-presenting capacities of mouse dendritic cells (DCs) from lymphoid organ (spleen DCs) and non-lymphoid tissue (liver DCs) during starvation. The total numbers of spleen DCs and liver DCs were significantly fewer in starved mice than in control mice. Functional analysis showed that the proliferative activities of spleen DCs and liver DCs were significantly impaired in starved mice compared with control mice. In particular, liver DCs from starved mice were unable to induce interferon-gamma. Liver DCs from starved mice were unable to induce proliferation of antigen-specific memory lymphocytes. These data indicated that one major cause of impairment of immunologic responses during starvation may be mediated through DCs. 相似文献

To increase the sustained response (SR) rate in chronic hepatitis C (CHC), we tried a combination therapy with interferon (IFN) alpha and beta. Fifty patients were grouped into 4 groups: group 1H (n=9), HCV serotype 1 and high HCV-RNA titer (over 6 log copies/ml); group 1L (n=11), HCV serotype 1 and low HCV-RNA titer (less than 6 log copies/ml); group 2H (n=23), HCV serotype 2 and high HCV-RNA titer; group 2L (n=7), HCV serotype 2 and low HCV-RNA titer. They were given a total dose of 768 MIU which included natural IFN beta (6 MIU) once daily for 28 consecutive days and then natural IFNalpha (10 MIU) three times a week for 20 weeks. Forty-nine patients with CHC receiving IFN alpha at total dose of 480 MIU served as single therapy group. In combination group, SR rate was achieved in 62%, 44% in 1H, 45% in 1L, 70% in 2H, and 86% in 2L, respectively. In single group, SR rate was achieved in 45, 14, 58, 60, and 82%, respectively. There was no significant difference for SR rate between combination group and single group. However, in patients with HCV-RNA titer between 6-7 log copies/ml of 1H group, SR rate in combination group (67%, 4/6) was significantly higher than that of single group (18%, 3/17) (p<0.05). These data suggest the usefulness of combination therapy with IFN alpha and beta in CHC with serotype 1 having moderately high HCV-RNA titer. 相似文献

A vancomycin-intermediate Staphylococcus aureus (VISA) isolated from the blood of a 46-year-old patient with endocarditis was determined to be pulsed-field type USA300, daptomycin nonsusceptible, and positive for the Panton-Valentine leukocidin genes. Development of the VISA phenotype does not appear limited to traditional health care strains of S. aureus. 相似文献
