Rescue therapy by portal infusion of autologous stem cells in a case of drug-induced hepatitis.
Recent efforts have been directed toward new therapeutic options to approach drug-induced hepatitis. We report a case of acute liver failure associated with Nimesulide in a 67-year-old man, with a medical history of chronic alcohol abuse. The biopsy was compatible with chronic alcoholic liver disease and acute drug-induced injury. The patient was enrolled to receive G-CSF followed by apheresis and selection of peripheral-blood stem cells. After ultrasound-guided injection of CD34+cells in the portal vein, we observed a rapid improvement of synthetic liver function, with particular reference to coagulation parameters. Liver biopsy performed 20 days after, showed wide areas of regeneration. In the next 30 days the laboratory signs of acute decompensation progressively improved. Unfortunately he died of multiple-organ failure related to bacterial infection. Intrahepatic injection of peripheral-blood stem cells seemed safe and produced good periprocedural results with improvement of synthetic profile, suggesting a possible role of stem cells in the regeneration process.

Ischaemic jejunal vasculitis during treatment with pegylated interferon-alpha 2b and ribavirin for hepatitis C virus related cirrhosis.
A 53-year-old male with compensated cirrhosis (Child-Pugh class A5) and mixed cryoglobulinaemia (cryocrit: 2.0%), both hepatitis C virus-related, was treated with pegylated interferon-alpha 2b and ribavirin. After three months of therapy, he developed segmental jejunal vasculitis requiring emergency resection of an ischaemic intestinal loop 60cm long. Pathological examination of the surgical specimen revealed signs of ischaemic injury with haemorrhagic infarction due to arteritis and arterial occlusion. The postoperative course was complicated by progressive liver and renal failure that led to the patient's death six months after surgery. To our knowledge, ischaemic jejunal vasculitis has never been reported during interferon therapy, but the latter treatment may have played causative roles.

Prognostic factors for survival in patients with early-intermediate hepatocellular carcinoma undergoing non-surgical therapy: comparison of Okuda, CLIP, and BCLC staging systems in a single Italian centre.
BACKGROUND: Several prognostic models have been developed to stage hepatocellular carcinoma (HCC) but there is no general consensus on which is the most reliable. We compared three prognostic indices (Okuda, CLIP, and BCLC scoring systems) in a large series of cirrhotic patients with HCC undergoing non-surgical treatment in terms of their ability to classify patients into different risk groups METHODS: We retrospectively studied 268 Italian patients with HCC. A total of 146 patients were treated with ablation, 132 with percutaneous ethanol injection, and 14 with radiofrequency ablation; 103 underwent transcatheter arterial chemoembolisation and 19 had supportive care alone. Factors determining survival were analysed by univariate and multivariate analysis using the Kaplan-Meier method and Cox proportional hazard regression models. Okuda, CLIP, and BCLC scores evaluated before treatment were applied. RESULTS: Median survival was 25.7 months. In a multivariate analysis, portal vein thrombosis, alpha fetoprotein, total bilirubin, and tumour size were significant predictors of survival. Okuda, CLIP, and BCLC scores were all able to predict survival (p<0.001). They identified two, four, and six risk groups, respectively, with a median survival ranging from 27 to 19 months for Okuda, 30 to 5 months for CLIP, and 43 to 7 months for BCLC. CONCLUSIONS: Both CLIP and BCLC scores were more effective than the Okuda score in stratifying patients into different risk groups with early-intermediate HCC. However, the BCLC scoring system gave a better prediction of prognosis in patients with disease diagnosis at a very early stage.

Contrast-enhanced power doppler of the intestinal wall in the evaluation of patients with Crohn disease.
BACKGROUND: Crohn disease (CD) manifests with highly variable signs and symptoms, and assessment of the status of the disease in the single patient can be difficult. This study was conducted to evaluate the efficacy of power colour Doppler ultrasonography, with and without echo-enhancement, in distinguishing active from quiescent CD. METHODS: Resistance Index (RI) of the superior mesenteric artery (SMA), bowel thickness of the affected loops and the presence of colour signals at power Doppler analysis prior to and after ultrasonography contrast agent injection (Levovist) were evaluated in 48 patients with CD. RESULTS: In our series, 26/48 patients had active and 22/48 had quiescent CD. A CDAI score > or = 150 and a pathological (> 5 mg/dL) C reactive protein were significantly correlated with active disease (P < 0.001 and P = 0.004, respectively). Intestinal wall thickness showed no significant correlation with disease status (7.5 +/- 1.3 mm in active disease versus 6.8 +/- 1.3 mm in quiescent disease; P = 0.11). Vascular signals in the affected loops were revealed in 11/22 patients (50%) with active disease and in 5/26 (20%) with quiescent disease (P = 0.052). After Levovist injection, colour signals were found in 22/22 with active and in 8/26 with quiescent CD (P < 0.001). SMA RI was significantly lower in active CD patients (0.81 +/- 0.01 versus 0.83 +/- 0.02; P = 0.001). CONCLUSIONS: Our data suggest that in patients with CD a finding of a SMA RI < or = 0.81, or the presence of a colour signal in the wall of the affected loops, at power Doppler sonography, is indicative of active disease. Utilization of echo-enhancer media can greatly improve the diagnostic sensitivity of intestinal wall power Doppler scan. A finding of intestinal wall thickening is not associated with active disease in our series.

Liver transplantation: the Italian experience.
BACKGROUND: Liver transplantation is the standard treatment for patients with end-stage liver disease no longer responsive to conventional medical treatment AIMS: To report the long-term experience of liver transplantation in Italy. PATIENTS AND METHODS: Data were obtained retrospectively by means of a multiple-item form collected from 15 Italian liver transplant centres. The filing centre was centralized. RESULTS: A total of 3323 liver transplants were performed on 3026 patients, with a cumulative proportional survival of 72.4%. Three, 5 and 10 years' patient survival rates were 72.3%, 68.8% and 61.3%, respectively. The most common indication for liver transplantation were hepatitis B virus (+/- hepatitis D virus)- and hepatitis C virus-related cirrhosis (59.4%). Excellent survival rates were observed particularly in controversial indications, such as alcoholic cirrhosis, hepatitis B virus-related cirrhosis and hepatocellular carcinoma. Retransplantation was required in 8.9% of the cases. The overall prevalence of acute cellular rejection episodes was 43.5%. In our study population, primary non-function and disease recurrence were the most common causes of graft failure (28.7% and 25.4%, respectively). Infections and/or sepsis were the most common causes of death after transplantation (42%). CONCLUSION: This study confirms that patients with controversial indications to liver transplantation such as alcoholic cirrhosis, HBV-related cirrhosis and hepatocellular carcinoma can achieve excellent survival when properly selected.

The Italian experience on paediatric liver transplantation: 1988-1999 report.
BACKGROUND: Liver transplantation is the treatment of choice for end-stage liver disease in both adult and paediatric patients. The Italian experience in paediatric liver transplantation during the period 1988-1999 is reported herein. PATIENTS AND METHODS: This report concerns 228 liver transplantations performed in 207 patients (100 male, 107 female, mean age 5.1+/-4.4 years) in 11 Italian centres. The mean waiting time on the transplantation list was 6.1+/-8.9 months and the main indications for the procedure were biliary atresia, inborn metabolic disorders, liver cirrhosis, liver neoplasms, Alagille syndrome, and fulminant hepatic failure. RESULTS: The cumulative survival rate was 77%, 76%, 73%, and 71% at 1, 3, 5, and 7 years. The overall prevalence of acute rejection was 54%. Survival was significantly affected by re-transplantation (p=0.0002), by United Network for Organ Sharing 4 status at transplantation (p=0.016), and, among the indications for the procedure, by fulminant hepatic failure (p=0.004). Fifty patients (24%) died during the observation period. The main causes of death were primary non-function of the graft and sepsis CONCLUSIONS: This study shows that liver transplantation in paediatric age, in Italy, is an effective procedure providing a 5-year survival rate comparable to that attained in the largest published series.

Prognostic factors for survival in patients with compensated cirrhosis and small hepatocellular carcinoma after percutaneous ethanol injection therapy.
BACKGROUND: The objective of this study was to identify clinical, biochemical, ultrasound, and/or pathologic parameters capable of predicting survival in a cohort of patients with well compensated cirrhosis and small hepatocellular carcinoma (HCC) who were treated with percutaneous ethanol injection (PEI). METHODS: The study group included 111 patients with Child--Pugh Class A cirrhosis and with one (93 patients) or two (18 patients) HCC nodules measuring < 5 cm in greatest dimension. All patients underwent multisession PEI. The prognostic values of pretreatment and post-treatment variables were analyzed using the Kaplan-Meier method. RESULTS: The overall 3-year and 5-year survival rates of 62% and 41%, respectively, were not influenced by age, gender, duration of chronic hepatitis, serum albumin, prothrombin time ratio, total bilirubin, gamma-glutamyl transferase, hepatitis B surface antigen, antihepatitis C virus, HCC size, HCC ultrasound pattern, HCC histologic or cytologic grading, greatest spleen dimension, esophageal varices, or ascites. Levels of alpha-fetoprotein (AFP) > 14 ng/mL (P < 0.006), alanine aminotransferase > 75 IU/L (P < 0.04), and aspartate aminotransferase > 80 IU/L (P < 0.009) and platelet count < 92 x 10(9)/L (P < 0.02) before treatment were independent predictors of decreased survival. Among post-treatment parameters, AFP levels 6 months after PEI > 13.3 ng/mL (P < 0.003) and HCC recurrence in another segment of the liver (P < 0.04) were linked to decreased survival in univariate analysis. CONCLUSIONS: Among patients with Child--Pugh Class A cirrhosis with small uninodular or binodular HCC who are treated with multisession PEI, those with elevated serum AFP and transaminase levels and low platelet count before treatment are characterized by decreased survival. During follow-up, intrahepatic recurrence of the tumor is the main factor affecting survival.

Comparison between color power Doppler ultrasound with echo-enhancer and spiral computed tomography in the evaluation of hepatocellular carcinoma vascularization before and after ablation procedures.
OBJECTIVE: Use of new echo enhancers capable of passing the lung filter has extended the clinical applications of color power Doppler flow imaging in many diseases and appears promising in the study of neoplasm vascularization. Levovist (Shering, Berlin Germany) is an ultrasound contrast agent containing galactose microbubbles suspended in palmitic oil. The sensitivity of Levovist-enhanced color power Doppler was compared to that of standard color power Doppler and contrast-enhanced spiral computed tomography (CT) in the detection of vascular signals in hepatocellular carcinoma. METHODS: We examined 29 hepatocellular carcinoma nodules in cirrhotic livers that had appeared avascular on unenhanced color power Doppler. Color power Doppler studies were repeated with and without Levovist enhancement before (15 examinations) and/or after (23 examinations) percutaneous ablation procedures. Findings (vascularized vs nonvascularized) were compared to those obtained with contrast-enhanced spiral computed tomography (gold standard) performed no more than 24 h after each of the 38 Doppler examinations. RESULTS: In pretreatment studies, Levovist-enhanced power Doppler correctly revealed vascularization in 12 of 15 lesions that had appeared avascular without echo enhancement and confirmed the avascularity of one other nodule; the remaining two, which appeared avascular on contrast-enhanced Doppler, displayed vascularization on the spiral CT examination. Levovist-enhanced power Doppler was fully concordant with spiral CT findings in all of the posttreatment examinations. CONCLUSION: Considering the absence of false positive results in this study, echo-enhanced color power Doppler can be considered reliable in diagnosing incomplete necrosis of hepatocellular carcinomas after percutaenous ablation. Spiral computed tomography can thus be reserved for those cases in which the enhanced power Doppler examination reveals no evidence of vascularity.

Gross pathologic types of hepatocellular carcinoma in Italy.
The prevalence and independent predictors of the different macroscopic types of hepatocellular carcinoma (HCC) were assessed in 1,073 unselected patients of 14 hospitals in Italy from May 1996 to May 1997. Solitary HCC was the most common cancer type (44.6%), followed by multinodular (44.2%), diffuse (8.4%) and massive (2.8%) types. After adjustment for the influence of confounders by multiple logistic regression analysis, Child-Pugh grades B and C were found to be independent predictors of multinodular (odds ratio, OR, 2.0; 95% confidence interval (CI) = 1.5-2.6) and diffuse (OR 2.6; 95% CI = 1.6-4.4) HCC types. These findings indicate that the majority of HCC cases are not detected at a potentially treatable stage. Delayed detection of HCC is associated with a higher likelihood of the multinodular or diffuse gross pathologic type.

Doppler ultrasonographic evaluation of the early changes in renal resistive index in cirrhotic patients undergoing liver transplantation.
Renal vasoconstriction commonly occurs in decompensated liver cirrhosis and is entirely reversible after hepatic transplantation. In this study we evaluated by Doppler ultrasonography the changes of renal vascular resistance occurring during the first month after transplantation. In 16 cirrhotic patients the intrarenal resistive index at the level of interlobar arteries and the blood urea nitrogen and serum creatinine levels were measured before (range, 1 to 34 days) and after transplantation (days 1, 3, 7, 14, 30). Before transplantation the median resistive index value was 0.69 (95% CI, 0.65 to 0.71) and eight of 16 patients showed abnormal values (0.70 or more). After transplantation, the median resistive index was significantly decreased on all the evaluation days, and no patient had abnormal values on posttransplantation day 7. No significant correlation was found between resistive index and serum creatinine or blood urea nitrogen levels. Doppler ultrasonography is a simple tool to evaluate the recovery of normal intrarenal arterial resistance levels after liver transplantation. One week appears to be the optimal timing to evaluate the renal resistive index in the posttransplantation period.

Characteristics of hepatocellular carcinoma in Italy.
BACKGROUND/AIMS: This study aimed to assess the main features of hepatocellular carcinoma at the time of diagnosis in Italy, particularly in relation to the presence or absence of underlying cirrhosis, hepatitis virus marker patterns, age of the subjects and alpha-foetoprotein values. METHODS: A total of 1148 patients with hepatocellular carcinoma seen at 14 Italian hospitals in the 1-year period from May 1996 to May 1997 were the subjects of this prevalence study. Both newly diagnosed cases (incident cases) and cases diagnosed before May 1996 but still attending the hospitals during the study period (prevalent cases) were included. RESULTS: We found that 71.1% of cases were positive for hepatitis C virus antibodies but negative for HBsAg; in contrast, 11.5% were negative for anti-HCV but positive for HBsAg; 5.3% were positive for both markers; and 12.1% were negative for both viruses. The mean age of detection was over 60 years, with a younger mean age in HBsAg-positive compared to anti-HCV-positive patients (59.3 years vs. 65.6 years, p<0.01). The male-to-female ratio among HBsAg-positive patients was 10.4:1, in contrast to 2.8:1 among anti-HCV-positive patients (p<0.01). The majority of cases (93.1%) had underlying cirrhosis. Cirrhotic patients were more likely to be anti-HCV positive than non-cirrhotic cases (73.2% vs 43.9%; p<0.01); conversely, absence of hepatitis virus markers was more frequently observed in the non-cirrhotic than in the cirrhotic population (40.9% vs. 10.0%; p<0.01). Overall, the alpha-foetoprotein level was altered (>20 ng/ml) in 57.9% of patients; only 18% of cases presented diagnostic (>400 ng/ml) values. Anti-HCV positivity (O.R. 2.0; CI 95%=1.3-3.1) but not HBsAg positivity (O.R. 1.0; CI 95%=0.6-1.8) was shown to be an independent predictor of the likelihood of altered alpha-foetoprotein values by multivariate analysis. CONCLUSIONS: These findings point to differences in the characteristics of the populations infected by hepatitis B and hepatitis C. Factors other than the hepatitis viruses are important in non-cirrhotic patients. A change in the relative prevalence of hepatitis virus markers among hepatocellular carcinoma cases was demonstrated, reflecting a significant change in the rate of HBV endemicity in the Italian population. Finally, the increased trend in the mortality rate from liver cancer in Italy from 4.8 per 100,000 in 1969 to 10.9 in 1994 may reflect the large cohort of subjects infected with HCV via the iatrogenic route during 1950s and 1960s when glass syringes were commonly used for medical treatment.

Early renal involvement in diabetes mellitus: comparison of renal Doppler US and radioisotope evaluation of glomerular hyperfiltration.
PURPOSE: To evaluate the usefulness of Doppler ultrasonography (US) in the diagnosis of hyperfiltration in patients with insulin-dependent diabetes mellitus (IDDM). MATERIALS AND METHODS: Eighty-one consecutive patients with IDDM were studied. All patients were normotensive and had normal creatinine and blood urea nitrogen levels. The glomerular filtration rate (GFR) was evaluated by means of plasma clearance of chromium-51 ethylenediaminetetraacetic acid, urinary albumin excretion, US evaluation of renal volume, and Doppler evaluation of resistance index (RI) in the renal interlobar arteries. The patients were divided according to GFR into the following groups: those with hyperfiltering kidneys (group 1, n = 40) and those with normofiltering kidneys (group 2, n = 41). RESULTS: The median renal volume was 351 mL (95% CI = 337 mL, 379 mL) in group 1 and 318 mL (95% CI = 300 mL, 335 mL) in group 2 (P = .005). The number of patients with microalbuminuria was significantly lower in group 1 than in group 2 (P = .02). The median RI was significantly lower in group 1 (0.55; 95% CI = 0.53, 0.57) than in group 2 (0.57; 95% CI = 0.56, 0.59) (P = .04). An RI of less than 0.5, a renal volume greater than 410 mL/m2, and the absence of microalbuminuria were independent predictors of hyperfiltration. An RI of less than 0.5 and a renal volume greater than 410 mL/m2 showed high specificity (98% and 95%, respectively) and poor sensitivity (25% and 23%, respectively) in the diagnosis of hyperfiltration in IDDM patients. CONCLUSION: Both RI and renal volume showed correlation with GFR, but neither parameter is sufficiently sensitive in screening for hyperfiltration in IDDM patients.

Risk factors for intrahepatic recurrence of hepatocellular carcinoma in cirrhotic patients treated by percutaneous ethanol injection.
BACKGROUND: Hepatocellular carcinoma (HCC) complicating cirrhosis has a high intrahepatic recurrence rate after treatment by surgical resection or percutaneous ethanol injection (PEI). In this study, certain clinical, biochemical, and pathologic parameters were evaluated as risk factors for intrahepatic tumor recurrence in liver segments different from that of the first neoplasm in a group of 57 cirrhotic patients with single HCC < 5 cm treated by PEI. METHODS: After PEI treatment of HCC, the patients were followed for a mean period of 33 +/- 16 months. The following pretreatment parameters were evaluated as predictors of tumor recurrence: age, gender, Child-Pugh score, hepatitis B virus surface antigen, hepatitis C virus antibodies, alanine aminotransferase, aspartate aminotransferase, alpha-fetoprotein (AFP) level before PEI, alcohol abuse, HCC size, HCC ultrasound pattern, HCC histologic grade, HCC capsule, and time from cirrhosis diagnosis. Furthermore, the posttreatment parameters of the AFP level 1 month after PEI and recurrence of HCC in the same liver segment were also evaluated. RESULTS: The cumulative 4-year intrahepatic recurrence rate of HCC was 62%. The log rank test indicated that, among pretreatment parameters, time from cirrhosis diagnosis > 6 years (P = 0.05) and AFP level before PEI of > 25 ng/mL (P = 0.00005) were significantly linked to tumor recurrence. Cox's proportional hazards model showed that only AFP level before PEI was independently associated with recurrence (P < 0.002). With regard to posttreatment parameters, an AFP level 1 month after PEI of > 13 ng/mL was shown to be significantly related to tumor recurrence by the log rank test (P < 0.0001). CONCLUSIONS: Cirrhotic patients with single HCC treated by PEI who have slightly increased serum levels of AFP before and/or after PEI treatment are at increased risk of intrahepatic tumor recurrence and should undergo a close follow-up program.

Spontaneous intrahepatic portosystemic venous shunt in a patient with cirrhosis: diagnosis by combined color Doppler and pulsed Doppler ultrasonography.
Large spontaneous intrahepatic portosystemic venous shunts are occasionally found and their diagnosis by Doppler sonography is rarely reported. The authors describe a case of spontaneous intrahepatic porto-systemic venous shunt in liver cirrhosis diagnosed by color Doppler and characterized by an unusual pulsed Doppler spectrum: a continuous flat portal-like pattern of flow in the portal branch, and in both the shunt and the hepatic vein.

Doppler ultrasonographic evaluation of blood flow in the superior mesenteric artery in celiac patients and in healthy controls in fasting conditions and after saccharose ingestion.
We studied, by means of Doppler ultrasonography, the blood flow in the superior mesenteric artery in 12 untreated patients with celiac disease (nontropical sprue) and in 15 healthy controls; peak systolic velocity, end diastolic velocity, mean velocity, flow volume, and resistive index were measured in the fasting state and at regular intervals after ingestion of 0.5 liter of water containing 50 g of saccharose. Under fasting conditions, celiac patients showed peak systolic velocity, end diastolic velocity, mean velocity, and flow volume values significantly higher than those of normal subjects, whereas resistive index was significantly lower. After saccharose ingestion these parameters showed greater variations in normal subjects than in celiac patients. Fasting end diastolic velocity turned out to be the best parameter to distinguish celiac patients from healthy subjects. Doppler ultrasonography of the superior mesenteric artery could discriminate between normal subjects and celiac patients with overt disease. However, these data need further confirmation given the limited sample that we studied; moreover, the capability of this technique in distinguishing nontropical sprue from other gastrointestinal diseases that cause increasing splanchnic flow remains to be ascertained.
