RESUMO

BACKGROUND AND AIM: Fasudil, a Rho-kinase inhibitor, has been shown to reduce portal venous pressure in cirrhotic rats. However, its effects on portal and systemic hemodynamics have not been investigated in cirrhotic patients with portal hypertension. The aim of this study was to assess the effects of fasudil on the portal and systemic hemodynamics of cirrhotic patients with portal hypertension. METHODS: Twenty-three patients with cirrhosis and portal hypertension were studied. Systemic and portal hemodynamics were measured prior to and 50 min after the initiation of intravenous administration of 30 mg fasudil (n = 15) or placebo (n = 8). RESULTS: After fasudil, there were significant decreases in both mean arterial pressure (P < 0.05) and systemic vascular resistance (P < 0.05), whereas the heart rate increased significantly (P < 0.05). There was a significant decrease in the hepatic venous pressure gradient (P < 0.05). Portal vascular resistance also decreased significantly (P < 0.01). Placebo caused no significant effects. There were no symptomatic reactions caused by changes in the mean arterial pressure or heart rate after fasudil. CONCLUSIONS: In cirrhotic patients with portal hypertension, fasudil lowers portal vascular resistance, resulting in decreased portal venous pressure with reducing arterial pressure.

RESUMO

AIM: The aim of this study was to investigate the predictive factors for the response of ascites to a transjugular intrahepatic portosystemic shunt (TIPS) and the impact of improvement of ascites on the overall prognosis of patients with cirrhosis and refractory ascites. METHODS: Forty-seven consecutive patients with liver cirrhosis who underwent TIPS for refractory ascites were studied retrospectively. The mean follow-up period was 615 ± 566 days. RESULTS: Thirty-six of the patients (77%) were responders at 4 weeks after TIPS (early responders) and 37 (79%) were responders at 8 weeks after TIPS. Of the 11 non-responders at 4 weeks, four showed an improvement of ascites at 8 weeks. Multivariate analysis showed that only the serum creatinine level before TIPS was an independent predictor of an early response. The cumulative survival rate of early responders was significantly higher than that of non-responders. The survival of patients grouped according to creatinine level was better in patients with serum creatinine of 1.9 mg/dL or less than in those with serum creatinine of more than 1.9 mg/dL. CONCLUSION: A low serum creatinine level in patients with refractory ascites is associated with an early response to TIPS. An early response of ascites to TIPS provides better survival. A serum creatinine level below 1.9 mg/dL is required for a good response to TIPS.

RESUMO

BACKGROUND: The introduction of capsule endoscopy (CE) has facilitated the detection of mucosal changes in the small bowel, and such mucosal changes have been noted in cirrhotic patients with portal hypertension; these changes are described as portal hypertensive enteropathy. The aim of this study was to assess the effects of transjugular intrahepatic portosystemic shunt (TIPS) on the small bowel mucosal changes detected by CE in cirrhotic patients with portal hypertension. METHODS: TIPS was performed in fifteen cirrhotic patients with portal hypertension. All patients underwent CE before and 2 weeks after TIPS. The small bowel mucosal changes were defined as edema, angiodysplasia-like lesions, red spots, and small bowel varices. Changes in the portosystemic pressure gradient (PSG) and CE findings were evaluated. RESULTS: Before TIPS, small bowel edema was detected in all 15 patients, angiodysplasia-like lesions in 7, and red spots in 14 patients. The PSG decreased significantly, from 21.2 ± 2.6 before TIPS to 8.9 ± 3.3 mmHg (p < 0.001) after the procedure. After TIPS, the small bowel edema was attenuated in 8 of the 15 patients. In two patients with angiodysplasia-like lesions and 4 with red spots, these lesions were attenuated after TIPS. The average score for small bowel edema and the grade of red spots were reduced significantly after TIPS (2.3 ± 0.7-1.8 ± 0.6, p < 0.005 and 1.6 ± 0.9-1.3 ± 0.7, p < 0.05, respectively). Small bowel varices were seen in 4 patients before TIPS and all these varices disappeared after TIPS. CONCLUSIONS: In cirrhotic patients with portal hypertension, small bowel edema, red spots, and small bowel varices were attenuated after TIPS. Portal hypertension may be an important factor in the development of small bowel mucosal changes.

RESUMO

BACKGROUND AND AIM: Although the anti-hepatitis C virus (HCV) effect of statins in vitro and clinical efficacy of fluvastatin combined with Pegylated interferon (PEG-IFN)/ribavirin therapy for chronic hepatitis C (CHC) have been reported, the details of clinical presentation are largely unknown. We focused on viral relapse that influences treatment outcome, and performed a post-hoc analysis by using data from a randomized controlled trial. METHODS: Thirty-four patients in the fluvastatin group and 33 patients in the non-fluvastatin group who achieved virological response (complete early virological response [cEVR] or late virological response [LVR]) with PEG-IFN/ribavirin therapy were subjected to this analysis. Factors contributing to viral relapse were identified by using multiple logistic regression analysis. RESULTS: Relapse rate in patients with cEVR was significantly lower in the fluvastatin group (2 of 23, 8.7%) than in the non-fluvastatin group (9 of 26, 34.6%; P = 0.042). The use of fluvastatin decreased relapse rate in patients with LVR (27.3% vs 57.1%), though not significantly. Overall, relapse rate was significantly lower in the fluvastatin group (14.7%; 5 of 34) than in the non-fluvastatin group (39.4%; 13 of 33; P = 0.027). Multivariate analysis identified absence of fluvastatin (P = 0.027, odds ratio [OR] = 3.98, 95% confidence interval [CI] = 1.05-15.11) and low total ribavirin dose (P = 0.002, OR = 2.41, 95% CI = 1.38-4.19) as independent factors contributing to relapse. CONCLUSION: The concomitant addition of fluvastatin significantly suppressed viral relapse, resulting in the improvement of sustained virological response rate, in PEG-IFN/ribavirin therapy for CHC patients with HCV genotype 1b and high viral load.

RESUMO

BACKGROUND AND AIM: The most important factor influencing the effect of pegylated interferon (PEG-IFN)/ribavirin therapy (PEG) for chronic hepatitis C genotype 1b with high viral load is the interleukin 28B (IL28B) genotype. We investigated the usefulness of lead-in twice-daily interferon (IFN)-ß/ribavirin therapy (IFN-ß), and the early hepatitis C virus RNA (HCV-RNA) dynamics was compared between PEG and IFN-ß groups according to the IL28B genotype. METHODS: Forty-six patients were randomly allocated to PEG and IFN-ß groups, and HCV-RNA dynamics in an early phase of treatment were analyzed. RESULTS: The patients with minor IL28B genotype was 6/23 and 8/23 in IFN-ß and PEG groups, respectively. In the patients with IL28B major genotype, viral load reduction was marginally greater in IFN-ß group than in PEG group. In contrast, in the patients with the IL28B minor genotype, viral load reduction was significantly and numerically greater in IFN-ß group than in PEG group at 1 week (2.07 vs. 0.76 log IU/mL, P = 0.038), 2 weeks (2.73 vs. 1.01, P = 0.009), 4 weeks (2.72 vs. 1.55, P = 0.059), and 12 weeks (4.56 vs. 3.24, P = 0.104). The sustained virological response rates in the IL28B major genotype were similar between IFN-ß group (47.1%, 8/17) and PEG group (53.3%, 8/15). In contrast, the sustained virological response rates in the IL28B minor genotype were numerically higher in IFN-ß group (50.0%, 3/6) than in PEG group (12.5%, 1/8), although not statistically significant. CONCLUSION: It was suggested that lead-in twice-daily IFN-ß/ribavirin treatment followed by PEG-IFN/ribavirin combination therapy may modify the HCV-RNA dynamics compared with that by PEG-IFN/ribavirin therapy, and it is particularly useful for the IL28B minor genotype.

RESUMO

BACKGROUND: Serum vitamin D concentration is reported to show a decrease in older age. Patients with chronic hepatitis C (CHC) in Japan are older on average than those in Western countries. Moreover, the outcome of pegylated-interferon (PEG-IFN)/ ribavirin therapy combined with vitamin D in elderly patients is unclear. OBJECTIVES: This pilot study explored the efficacy and safety of alfacalcidol as vitamin D source in PEG-IFN/ ribavirin combination therapy for elderly CHC patients infected with hepatitis C virus genotype 1b. PATIENTS AND METHODS: Consecutive twenty CHC patients aged ≥ 65 years were enrolled in this pilot study. Fifteen patients met the inclusion criteria and received PEG-IFN/ ribavirin therapy combined with alfacalcidol. Four-week lead-in of oral alfacalcidol was conducted, and it was subsequently and concurrently administered in PEG-IFN/ ribavirin combination therapy (vitamin D group). Age, gender, and IL28B genotype-matched patients, who received PEG-IFN/ ribavirin alone, were saved as control group (n = 15) to compare the treatment outcome with the vitamin D group. RESULTS: Subjects consisted of 14 males and 16 females, with a median age of 70 years (65-78). The serum 25 (OH) D3 concentration in females (20 ng/ml, 11-37) was significantly lower than males (27 ng/mL, 13-49) (P = 0.004). Sustained virological response (SVR) rates were 33.3% (5/15) in the control group and 80.0% (12/15) in the vitamin D group, respectively (P = 0.025). While no significant difference was shown in the (SVR) rate between the two groups among males (P = 0.592), in females the SVR rate was significantly higher in the vitamin D group (87.5%, 7/8) than the control group (25.0%, 2/8) (P = 0.041). The relapse rates in the groups with and without alfacalcidol were 7.7% (1/13) and 61.5% (8/13), respectively (P = 0.011). Interestingly, in females, the relapse in the control group was shown in 5 of 7 (71.4%), whereas in the vitamin D group the relapse rate was decreased (1/8, 12.5%) (P = 0.041). No specific adverse events were observed in the vitamin D group. CONCLUSIONS: PEG-IFN/ ribavirin combined with alfacalcidol may be effective and safe in elderly CHC patients. In particular, concomitant administration of alfacalcidol may lead to a reduced relapse rate, and consequently improving the SVR rate in elderly females.

RESUMO

A 72-year-old male with liver dysfunction and an increase in serum total protein/albumin (TP/Alb) ratio was referred to our hospital. There was a marked increase in serum immunoglobulin (Ig) G4 level (IgG/IgG4: 3,485/2,860 mg/dl). Diagnostic imaging did not reveal any enlargement of the pancreas or narrowing of the pancreatic duct. However, bilateral submaxillary gland swelling, sclerosing cholangitis, and retroperitoneal fibrosis were noted, suggesting multifocal fibrosclerosis. Histological examination of the submaxillary gland showed the infiltration of IgG4-positive plasma cells, although there was no narrowing of the pancreatic duct, leading to a diagnosis of IgG4-related disease with various extrapancreatic lesions. Systemic investigation before the introduction of steroid therapy revealed rectal cancer. After low-position anterior resection, steroid therapy was introduced, reducing the lesions. Recent studies have reported autoimmune pancreatitis/IgG4-related disease with malignant tumors. However, the association and pathogenesis remain to be clarified. Malignant tumors are detected before or after the treatment of autoimmune pancreatitis/IgG4-related disease; pretreatment diagnosis and post-treatment follow-up should be carefully performed, bearing in mind the concomitant development of malignant tumors.

RESUMO

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) has recently been reported to be effective in the treatment of cirrhotic patients with refractory ascites. However, the clinical utility of TIPS in the subset of refractory ascitic patients with good hepatic and renal function is uncertain. The aim of this study was to compare the efficacy of TIPS to that of large-volume paracentesis in cirrhotic patients with refractory ascites who have good hepatic and renal function. METHODS: Sixty cirrhotic patients with refractory ascites who presented with a Child-Pugh score of <11, serum bilirubin of <3 mg/dl and creatinine of <1.9 mg/dl were assigned randomly to TIPS (n = 30) or large-volume paracentesis plus albumin (n = 30). The primary endpoint was survival. The secondary endpoints were response to treatment and development of hepatic encephalopathy. RESULTS: The baseline characteristics were similar in the two groups. Seventeen patients treated with TIPS and 21 treated with paracentesis died during the study period. The cumulative probabilities of survival at 1 and 2 years were 80 and 64% in the TIPS group and 49 and 35% in the paracentesis group (p < 0.005). TIPS was significantly superior to paracentesis in the control of ascites (p < 0.005). Treatment failure was more frequent in the paracentesis group, whereas the frequency of hepatic encephalopathy was greater in the TIPS group. CONCLUSIONS: In cirrhotic patients with refractory ascites who have good hepatic and renal function, TIPS improves survival and provides better control of ascites than large-volume paracentesis.

RESUMO

BACKGROUND AND AIM: Terlipressin has been shown to be effective in the management of hepatorenal syndrome. However, how terlipressin exerts its effect on the renal artery is unknown. The aim of the present study was to assess the effects of terlipressin on systemic, hepatic and renal hemodynamics in cirrhosis. METHODS: Twenty-eight patients with cirrhosis and portal hypertension were studied. Systemic and hepatic hemodynamics, hepatic and renal arterial resistive indices and neurohumoral factors were measured prior to and 30 min after intravenous administration of 1 mg terlipressin (n = 19) or placebo (n = 9). RESULTS: After terlipressin, there were significant increases in both mean arterial pressure (P < 0.001) and systemic vascular resistance (P < 0.001), whereas heart rate (P < 0.001) and cardiac output (P < 0.001) decreased significantly. There was a significant decrease in the hepatic venous pressure gradient (P < 0.001). Portal venous blood flow also decreased significantly (P < 0.001). The mean hepatic arterial velocity increased significantly (P < 0.001). Although there was a significant decrease in the hepatic arterial resistive index (0.72 +/- 0.08 to 0.69 +/- 0.08, P < 0.001) and renal arterial resistive index (0.74 +/- 0.07 to 0.68 +/- 0.07, P < 0.001), portal vascular resistance was unchanged (P = 0.231). Plasma renin activity decreased significantly (P < 0.005), and there was a significant correlation between this decline and the decrease in renal arterial resistive index (r = 0.764, P < 0.005). The effects of terlipressin on systemic, hepatic and renal hemodynamics were observed similarly in patients with and without ascites. Placebo caused no significant effects. CONCLUSION: Terlipressin decreases hepatic and renal arterial resistance in patients with cirrhosis.

RESUMO

In this prospective cohort study, we evaluated the use of transjugular intrahepatic portosystemic shunt (TIPS) in 50 patients with refractory ascites and a Child-Pugh score of 9.8. The mean duration of follow-up was 592 days. Ascites improved in 96% at 1 year and in 93% at 2 years. The cumulative survival rate was 71%, 52% and 18% at 1, 2 and 5 years. The Child-Pugh score and the performance status score improved significantly after TIPS. Thirty six patients required shunt revision during follow-up, due to shunt stenosis. Hepatic encephalopathy which was able to be controlled medically occurred in 26 patients. Our results suggest that although shunt revision may be needed, TIPS can control refractory ascites in most survival cases and improve QOL. However, the 5-year survival rate is still low in our TIPS-treated patients with refractory ascites.
