Predictive value of liver cell dysplasia for development of hepatocellular carcinoma in patients with non-cirrhotic and cirrhotic chronic viral hepatitis.

AIMS: Hepatocellular carcinoma (HCC) frequently develops in patients with chronic viral hepatitis, especially in the cirrhotic stage. We retrospectively studied whether the presence of the putative preneoplastic lesions large liver cell dysplasia (LLCD) and/or small liver cell dysplasia (SLCD) in a needle liver biopsy of these patients are a risk factor for the development of HCC. METHODS AND RESULTS: The presence of LLCD and SLCD in the needle liver biopsy taken at the initial work-up of 115 patients with chronic hepatitis B or C was assessed retrospectively. LLCD and SLCD were present in the initial biopsy of, respectively, 35 (30%) and 25 patients (22%). During a mean follow-up of 107 months, 16 patients (14%) developed HCC and this occurred significantly more frequently in patients with cirrhosis, age > or = 55 years, LLCD or SLCD. Cirrhosis and LLCD were independent risk factors for HCC development. CONCLUSIONS: Our findings indicate that the presence of LLCD in a needle liver biopsy of patients with viral-induced chronic liver disease is an independent risk factor for the development of HCC. If these results are confirmed, the presence of LLCD can be used to identify a subgroup of patients at high risk for HCC requiring more intensive screening.

Hepatitis C virus genotypes: distribution and clinical significance in patients with cirrhosis type C seen at tertiary referral centres in Europe.

The aim of this study was to evaluate the distribution and clinical significance of hepatitis C virus (HCV) genotypes in European patients with compensated cirrhosis due to hepatitis C (Child class A) seen at tertiary referral centres. HCV genotypes were determined by genotype-specific primer PCR in 255 stored serum samples obtained from cirrhotics followed for a median period of 7 years. Inclusion criteria were biopsy-proven cirrhosis, absence of complications of cirrhosis and exclusion of all other potential causes of chronic liver disease. The proportion of patients with types 1b, 2, 3a, 1a, 4 and 5 were 69%, 19%, 6%, 5%, 0.5% and 0.5%, respectively. Kaplan-Meier 5-year risk of hepatocellular carcinoma (HCC) was 6% and 4% for patients infected by type 1b and non-1b, respectively (P=0.8); the corresponding figures for decompensation were 18% and 7% (P=0.0009) and for event-free survival were 79% and 89% (P=0.09), respectively. After adjustment for baseline clinical and serological features, HCV type 1b did not increase the risk for HCC [adjusted relative risk=1.0 (95% confidence interval=0.47-2.34)], whereas it increased the risk for decompensation by a factor of 3 (1.2-7.4) and decreased event-free survival by a factor of 1.7 (0.9-3.10). In conclusion, type 1b and, to a lesser extent, type 2, are the most common HCV genotypes in European patients with cirrhosis. HCV type 1b is not associated with a greater risk for HCC, but increases the risk for decompensation by threefold in patients with cirrhosis.

Intravenous cyclosporine versus intravenous corticosteroids as single therapy for severe attacks of ulcerative colitis.

BACKGROUND & AIMS: Cyclosporine has been effective in patients with steroid-refractory attacks of ulcerative colitis (UC). We investigated the effects of intravenous (IV) cyclosporine as single IV therapy (without glucocorticosteroids) for severe UC and compared these with the response to glucocorticosteroids. METHODS: Patients with a severe attack of UC were randomized to treatment with IV cyclosporine, 4 mg x kg(-1) x day(-1), or with methylprednisolone, 40 mg/day, in a randomized, double-blind, controlled trial. After 8 days, patients who had a response received the same medication orally in combination with azathioprine. Patients were followed up clinically, endoscopically, and by scintigraphy. Renal function was assessed using urinary inulin clearances. Endpoints were clinical improvement, discharge from the hospital, and remission up to 12 months after intravenous therapy. RESULTS: Thirty patients were included. After 8 days, 8 of 15 patients (53%) who received methylprednisolone had a response to therapy vs. 9 of 14 (64%) receiving cyclosporine. In nonresponders, 3 of 7 methylprednisolone patients and 1 of 3 cyclosporine patients improved when both treatments were combined. No serious drug-related toxicity was observed with either treatment. At 12 months, 7 of 9 patients (78%) initially controlled with cyclosporine maintained their remission vs. 3 of 8 (37%) initially treated with methylprednisolone. No clinically significant decrease of renal function was observed. CONCLUSIONS: Cyclosporine monotherapy is an effective and safe alternative to glucocorticosteroids in patients with severe attacks of UC.

Safety and efficacy of oral entecavir given for 28 days in patients with chronic hepatitis B virus infection.

Entecavir is an oral antiviral drug with selective activity against hepatitis B virus (HBV). We conducted a randomized, placebo-controlled, dose-escalating study in patients with chronic hepatitis B infection in which we evaluated the efficacy and safety of entecavir given for 28 days. Follow-up was 24 weeks. All doses of entecavir (0.05 mg, 0.1 mg, 0.5 mg, and 1.0 mg) showed a pronounced suppression of replication of the HBV with a 2.21, 2.29, 2.81, and 2.55 mean log(10) reduction of viral load, respectively. Approximately 25% of patients on entecavir showed a decline of HBV DNA below the limit of detection of the Chiron HBV-DNA assay (<0.7 MEq/mL). In the postdosing follow-up period patients who were treated with 0.5 and 1.0 mg of entecavir showed a considerably slower return in their HBV DNA levels to baseline compared with those patients treated with lower dosages (P <.05). All doses of entecavir were well tolerated with no significant difference between treated patients and those receiving placebo. No significant changes in alanine transaminase (ALT) levels within the dose groups and the placebo group between baseline and the end of treatment were observed. Three patients (9%) (1 each in the 0.05-, 0.1-, and 0.5-mg groups) experienced asymptomatic hepatitis flares 16 weeks (2 patients) and 24 weeks (1 patient) after withdrawal of entecavir. In conclusion, in this 28-day study of entecavir a pronounced decrease of HBV DNA was observed and there were no significant side effects in entecavir patients in comparison with placebo-treated patients.

Liver transplantation for polycystic liver disease.

Polycystic liver disease (PLD) may provoke massive hepatomegaly and severe physical and social handicaps. Data on orthotopic liver transplantation (OLT) for PLD are rare and conflicting. Conservative surgery (resection or fenestration) is indicated for large single cysts, but its value for small diffuse cysts is questionable. In addition, conservative surgery is not devoid of morbidity and mortality. OLT offers the prospect of a fully curative treatment, but controversy remains because those patients usually have preserved liver function. Thus, we reviewed our experience with OLT for PLD. Sixteen adult women underwent OLT for small diffuse PLD between 1990 and 1999. Mean age was 45 years (range, 34 to 56 years). Fourteen patients had combined liver and kidney cystic disease, but only 1 patient required combined liver and kidney transplantation, whereas 13 patients underwent OLT alone. Two patients had isolated PLD. Indications for transplantation were massive hepatomegaly causing physical handicaps (n = 16), social handicaps (n = 16), malnutrition (n = 4), and cholestasis and/or portal hypertension (n = 5). OLT caused no technical difficulty in 15 of 16 patients (surgery duration, 6.8 hours; range, 5 to 8 hours), with blood transfusions of 7.9 units (range, 0 to 22 units). One patient who underwent attempted liver-mass reduction pre-OLT died of bleeding and pulmonary emboli. Native liver weight was 10 to 20 kg. Posttransplantation immunosuppression consisted of cyclosporine or FK506, azathioprine, and steroids (discontinued at 3 months). Morbidity included biliary stricture (2 patients), revision for bleeding and hepatitis (1 patient), pneumothorax and subphrenic collection (1 patient), and tracheostomy (1 patient). One patient died of lung cancer 6 years posttransplantation. Both patient and graft survival rates are 87.5% (follow-up, 3 months to 9 years). Of 15 patients who underwent OLT alone, only 1 patient needed a kidney transplant 4 years after OLT. Kidney function has remained satisfactory in the other patients despite the use of cyclosporine or FK506 (last follow-up creatinine level, 1.55 mg/dL; range, 0.80 to 2.85 mg/dL). OLT had a dramatic impact on daily quality of life, enabling these patients to go back to a fully active life style. OLT offers the chance of a definitive treatment in patients with extensive, small, diffuse PLD that has evolved into severely handicapping hepatomegaly. In contrast to previous studies, combined liver and kidney transplantation is rarely needed. Patient symptoms and chances of definitive palliation offered by OLT must be balanced against the risks of transplantation and lifelong commitment to immunosuppression.

Type of donor aortic preservation solution and not cold ischemia time is a major determinant of biliary strictures after liver transplantation.

The development of biliary strictures (BSs) after liver transplantation (LT) continues to affect 10% to 30% of patients, causing substantial morbidity. The cause of BSs is multifactorial, including technical, immune, and, in particular, ischemic factors. The importance of adequate flushing of the peribiliary arterial tree has been stressed. We hypothesized that high-viscosity (HV) preservation solutions in the donor do not completely flush the small donor peribiliary plexus, leading to inadequate preservation of the bile ducts and posttransplant BSs. To test this hypothesis, we retrospectively compared the incidence of BSs in 2 groups of adults undergoing LT using different types of aortic preservation solution in the donor: group 1 (n = 24), low-viscosity (LV) Marshall solution; and group 2 (n = 27), HV University of Wisconsin (UW) solution. All donors in both groups received additional portal flushes with UW. All LTs were performed between November 1995 and August 1998 at 2 centers by the same surgeon, eliminating a technical bias. Terminal duct-to-duct anastomosis was performed in all recipients except 1 patient in group 1, who underwent a bile duct-to-jejunum anastomosis. BSs were first suspected on clinical and biochemical grounds and then confirmed by endoscopic retrograde cholangiopancreatography. Identical medical protocols were used in all patients. One-year patient survival rates in groups 1 and 2 were 92% and 100%, respectively (P =.9). One-year graft survival was identical to patient survival. The incidence of BSs in group 1 was 4.1% (1 of 24 patients), compared to 29.7% in group 2 (8 of 27 patients; P =.02). The BS in group 1 occurred 4 months post-LT and was anastomotic. BSs in group 2 occurred between 1 and 12 months post-LT and were anastomotic, extrahepatic, intrahepatic, or combined intrahepatic and extrahepatic. There were no significant differences in the following factors between groups 1 and 2: donor age, local versus imported liver, split-liver or full-liver transplantation, incidence of multiple vessels in the donor liver, indications for LT, recipient age, T-tube versus no T-tube, post-LT peak aspartate aminotransferase level, and treatment for rejection. There was no hepatic artery thrombosis or primary nonfunction in either group. Interestingly, cold ischemia time (CIT) was longer in group 1, which had the least incidence of BSs (692 +/- 190 v 535 +/- 129 minutes in group 2; P =.001). Follow-up was longer in group 1 (28.9 +/- 8.3 v 15.6 +/- 8 months in group 2; P =.0001). Preservation costs per procurement were 1.9 times greater in the UW group than in the Marshall group. Donor aortic flushing with an HV preservation solution leads to more frequent BSs compared with an LV preservation solution. The impact of preservation solution outweighs the previously described deleterious impact of prolonged CIT. Mixed preservation solution (Marshall solution in the aorta, UW solution in the portal vein) might protect against BS formation while providing optimal liver graft preservation, function, and survival despite a mean CIT longer than 10 hours.

Transplantation osteoporosis and corticosteroid-induced osteoporosis in autoimmune diseases: experience with alfacalcidol.

The effect of alfacalcidol therapy on bone mineral density at the spine and proximal femur was evaluated in 112 transplant recipients (59 heart, 26 liver and 27 lung); 45 transplant cases served as controls (included in a randomised way in a placebo group) and in 42 rheumatoid arthritis cases. Liver and lung transplantation cases had before transplantation a lower bone density at the spine and femur compared to heart transplant cases. Heart transplant cases lost considerably more bone immediately after transplantation than liver and lung transplant recipients. A positive effect of 2 years alfacalcidol treatment (0.5-1 microgram/day) on bone loss was observed in all treated groups. Alfacalcidol was particularly effective against trabecular bone loss at the spine in rheumatoid arthritis patients and transplant recipients. There is a manifest difference in evolution between organ transplant groups and bone sites measured. Liver and lung transplant recipients respond better to therapy than cardiac recipients.

Oesophageal varices: assessment of the risk of bleeding and mortality.

Patients with oesophageal varices run a high risk of bleeding and even death, however rates of bleeding and mortality vary greatly. Indeed, a number of patients with varices never bleed. Prophylactic therapy is effective, but can be associated with side-effects. It remains to be determined which patients are at high risk of bleeding and require treatment. In addition, since non-response to medical therapy has been reported to occur in 20-40% of patients, the effect of a given prophylactic drug, or combinations of drugs, needs to be tested. A review is given of available methods of assessment. The Hepatic Venous Pressure Gradient, and measurements of the variceal pressure, are two proven methods, and the latter has the advantages of being non-invasive and having value in presinusoidal portal hypertension.

Variceal pressure is a strong predictor of variceal haemorrhage in patients with cirrhosis as well as in patients with non-cirrhotic portal hypertension.

BACKGROUND: Variceal pressure is a strong predictor for a first variceal bleed in patients with cirrhosis. AIMS: To evaluate whether variceal pressure is also a determinant of the risk of a first variceal bleed in patients with non-cirrhotic portal hypertension. METHODS: Variceal pressure was measured non-invasively in 25 patients with non-cirrhotic portal hypertension and large varices while receiving a stable therapeutic regimen. Factors predictive of bleeding were compared with those observed in 87 cirrhotics. RESULTS: The one year incidence of variceal bleeding was 32% (n=28) for the cirrhotic and 20% (n=5) for the non-cirrhotic patients. There was no difference in factors predicting the risk of bleeding between the groups, except for variceal pressure. For the same level of variceal pressure, the risk of variceal bleeding was lower in patients with non-cirrhotic portal hypertension. Multiple logistic regression analysis revealed the following variables as having a significant predictive power: variceal pressure (p=0.0001), red spots (p=0.004), and the time interval between the first observation of the varices and the moment of variceal pressure measurement (p=0. 0046). For the non-cirrhotics the risk of bleeding increased with higher Child-Pugh score (p=0.0024); this was not the case for the cirrhotic patients (p=0.9521). CONCLUSION: Variceal pressure is a major predictor of variceal bleeding in patients with cirrhosis as well as in patients with non-cirrhotic portal hypertension. The risk of bleeding in non-cirrhotics is less than in cirrhotics for the same level of variceal pressure. In patients with non-cirrhotic portal hypertension the risk of variceal bleeding increases more with advancing disease.

Resource analysis of somatostatin in the treatment of bleeding esophageal varices.

Association of vasoactive drugs such as somatostatin improves the therapeutic outcome of emergency sclerotherapy in case of a variceal bleeding. Systematic use of combination therapy will increase treatment costs in the initial period, but since it has the potential to reduce the need for rescue treatment and to reduce bleeding-related complications, it might save costs overall. A recent resource analysis performed in a small group of patients in our unit provides evidence for this hypothesis. Nevertheless, further research should better clarify which parameters justify combination of different treatment modalities for variceal bleeding.

Variceal pressure is a factor predicting the risk of a first variceal bleeding: a prospective cohort study in cirrhotic patients.

Predictive criteria for a first variceal hemorrhage lack substantial accuracy. Cross-sectional studies suggest a close relationship between variceal pressure (VP) and the occurrence of variceal bleeding. In the present prospective cohort study, the significance of VP measurement for prediction of a first variceal bleed was assessed. Eighty-seven patients with cirrhosis and large esophageal varices who had never developed variceal bleeding were followed for 12 months. The endpoint of the study was the presentation or not of a variceal hemorrhage. Thirty-four patients (39%) were in Child's class A, 37 in class B (43%), and 16 in class C (18%). The median interval between endoscopic diagnosis of varices and the beginning of the study was 15 months. Twenty-eight patients (32%) developed a variceal hemorrhage with a bleeding-related mortality of 18% (n=5). The 1-year mortality overall was 16% (n=14). Variables predictive of a first bleed identified by Cox proportional hazards regression model were: the level of VP, the North Italian Endoscopic Club (NIEC) score, and the interval between the diagnosis of varices and the start of the study. By adding VP to NIEC, a significant gain in prognostic accuracy was obtained (P = .003). In conclusion, the present study provides evidence that the level of VP is a major predictive factor for variceal hemorrhage, and that it provides further prognostic information in addition to the NIEC index.

Efficacy of interferon dose and prediction of response in chronic hepatitis C: Benelux study in 336 patients.

BACKGROUND/AIMS: In an attempt to improve the limited efficacy of treatment of chronic hepatitis C with interferon-alpha 3 MU tiw, we studied the effects of double-dose therapy followed by downward titration, and analyzed the pre- and pertreatment factors associated with response or non-response. METHODS: Three hundred and fifty-four consecutive patients in 19 centers were randomized to interferon-alpha 3 MU tiw for 6 months or 6 MU tiw for 8 weeks followed by down-titration (3,1 MU tiw) till alanine aminotransferase remained normal and plasma HCV RNA was repeatedly undetectable. The primary outcome measure was sustained alanine aminotransferase and HCV RNA response 6 months after treatment. RESULTS: Three hundred and thirty-six patients received treatment. The sustained response rate for patients receiving 3 MU tiw for 6 months was 14% (9-21%,) and for patients receiving double dose tiw for 8 weeks and thereafter titrated therapy 15% (10-21%) (p=0.8). Pretreatment factors associated with a sustained alanine aminotransferase plus HCV RNA response were the absence of cirrhosis, presence of genotype 2 or 3, a low viral load and, in addition, a low alanine aminotransferase/aspartate aminotransferase ratio; a model was developed to allow estimation of the chance of response for the individual patient. The most powerful predictor of sustained response, however, was plasma HCV RNA at week 4; a positive test virtually precluded a sustained response (1.7%, 0.4-5.0%). If week 4 HCV RNA was not detectable, the chance of a sustained response was 21% (12-34%) for genotype 1 versus 40% (28-54%) for the others (p=0.02). Six MU tiw led to a significantly higher week 4 HCV RNA response (47% not detectable) than 3 MU (37%) (p=0.02). During down-titration this difference in viral on-treatment response was lost. CONCLUSIONS: In the treatment of hepatitis C, an early HCV RNA response is a prerequisite for long-term efficacy. Doubling the initial interferon dose increases this early response, but subsequent downward titration negates this effect, especially in genotype 1.

Quantitative hepatitis B virus DNA assessment by the limiting-dilution polymerase chain reaction in chronic hepatitis B patients: evidence of continuing viral suppression with longer duration and higher dose of lamivudine therapy.

Lamivudine, a novel cytosine analogue, exhibits potent antiviral activity against hepatitis B virus (HBV) in vitro and in vivo. The standard HBV DNA hybridization assay used in phase II clinical studies has a low sensitivity, the detection limit of HBV DNA levels being approximately 10(7) genome equivalents per ml (geq ml-1). In this work we used a semiquantitative polymerase chain reaction (PCR) assay (detection limit approximately 10(3) geq ml-1) to determine HBV DNA levels during a 24-week study of lamivudine in 51 stable chronic hepatitis B patients who were positive for hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg). Patients were randomly allocated to receive oral doses of 25, 100 or 300 mg lamivudine once daily. At week 24 the median serum concentration of HBV DNA had fallen from 10(8) to 10(4) geq ml-1, a 4-log median reduction. A trend towards more profound suppression of viral replication with an increased dose of lamivudine was observed. After 12 weeks of therapy, 12% of patients had an HBV DNA level that was undetectable in the PCR assay; this increased to 26% after 24 weeks, while in an additional 20% of patients, HBV DNA decreased to the level of detection of the PCR assay. We conclude that a 24-week course of lamivudine decreases serum HBV DNA to the level of PCR detection in 46% of patients. Such additional viral suppressive activity with higher doses and more protracted lamivudine may be of clinical utility prior to liver transplantation. Further studies are needed to define the degree of virus suppression required in clinical practice, and methods are required to increase the efficacy of virus suppression.

Hepatitis G virus infection in acute fulminant hepatitis: prevalence of HGV infection and sequence analysis of a specific viral strain.

Hepatitis G virus (HGV) is a recently discovered RNA virus, which belongs to the Flaviviridae family. Although HGV infection is usually not associated with elevated serum transaminases, some recent studies have reported that HGV infection is found in a significant number of patients with fulminant hepatitis and may play a role in its etiopathogenesis. In this study the prevalence of HGV infection was determined in 500 healthy blood donors and in 24 patients admitted to hospital because of acute liver failure caused by fulminant hepatitis. The presence of HGV RNA was tested in sera, obtained at admission and before any transfusion was given, by a sensitive seminested reverse transcriptase-polymerase chain reaction (RT-PCR) assay specific for detection of the non-structural (NS)5 region. Nine of the 500 blood donors (1.8%) and two of the 24 patients (8.3%) were found to be HGV RNA positive. One patient was co-infected with HCV and was known to be an intravenous (i.v.) drug user. After intensive supporting treatment, this patient recovered completely. The second patient had no serological markers of known viral hepatitis infection, including hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), cytomegalovirus (CMV), Epstein-Barr virus (EBV) and herpes simplex virus (HSV). This patient was successfully transplanted. From both patients, from HGV RNA-positive healthy blood donors and from other patients coinfected with HCV, a part of the HGV NS3 region (nucleotides 4191-4345, EMBL entry U45966) was cloned and sequenced. Sequence comparison revealed that the NS3 region of HGV in patients with fulminant hepatitis contained three nucleotide substitutions as part of the six substitutions described in previous work. These nucleotide substitutions were not found in the tested blood donors or in patients with HCV co-infection. Our findings therefore support the concept of the association of fulminant hepatitis with infection of a specific HGV strain.

Hepatitis C virus genotypes: epidemiological and clinical associations. Benelux Study Group on Treatment of Chronic Hepatitis C.

In a cohort of 292 chronic hepatitis C patients living in the Benelux countries the relationship between viral genotype and geographical origin, route of transmission, clinical characteristics and severity of liver disease was analyzed. HCV-RNA isolates could be classified by the Line Probe Assay (LiPA) as 1a, 1b, 2, 3, 4 or 5 in 286 (98%) cases. Patients of European origin were predominantly infected with HCV subtype 1b (164/254, 65%, CI 58-70%), as were patients of Asian origin (7/13, 54%). Patients originating from Surinam (South America) had predominantly type 2 (9/10, 90%), whereas Africans were mainly infected with type 4 (7/9, 77%). Blood transfusion was the mode of transmission in 142 (50%) patients, intravenous drug abuse (IVDA) in 40 (14%), occupational needle accident or tattoo in 11 (4%); no obvious source of infection was found in 93 (33%). In patients infected by blood transfusion, subtype 1b was predominant (70%, CI 61-77%), whereas subtypes la and 3 were predominant in those infected by IVDA (25% and 45%, respectively, p<0.001). Cirrhosis was observed in 68 (24%) patients; in multivariate analysis, factors independently related to cirrhosis were: the duration of infection, age and prior hepatitis B. No significant relationship was found between the severity of fibrosis or liver inflammation and the HCV (sub)types. In summary, in this large cohort of patients in the Benelux countries the hepatitis C virus (sub)type present was clearly related to the country of origin and the route of transmission, but not to the severity of liver disease.

Early administration of somatostatin and efficacy of sclerotherapy in acute oesophageal variceal bleeds: the European Acute Bleeding Oesophageal Variceal Episodes (ABOVE) randomised trial.

BACKGROUND: Sclerotherapy is widely used for acute variceal bleeding, although in emergencies bleeding makes it difficult to obtain the clear view required for safe and effective treatment. We investigated whether early administration of somatostatin would improve the efficacy of sclerotherapy. METHODS: In this double-blind, prospective trial, patients who had cirrhosis with upper-gastrointestinal bleeding were randomly assigned natural somatostatin (6 mg per 24 h) or placebo for 120 h. In addition, intravenous bolus doses of somatostatin (250 micrograms) or placebo were injected after the start of the infusion, before emergency endoscopy or sclerotherapy, and when active bleeding was observed. The primary endpoint was treatment failure, defined as the occurrence during the infusion period of at least one of: excess transfusion of blood products, haematemesis, haemodynamic instability, need for rescue therapy, or death. FINDINGS: 205 patients were enrolled: 101 received somatostatin and 104 received placebo. Treatment failed in 35 somatostatin and 57 placebo recipients (p = 0.004); death or use of rescue therapy occurred in nine and 19 patients, respectively (p = 0.05). The mean quantity of blood products transfused over 120 h (adjusted for baseline haemoglobin) was 2.64 (SD 0.35) units in the somatostatin group versus 3.62 (0.35) units in the placebo group (p = 0.05). At endoscopy, active bleeding from oesophageal varices was less frequent (27 vs 42 patients, p = 0.012) and the sclerotherapy procedure was easier (2.8 vs 4.7 cm, p = 0.0027) in the somatostatin than in the placebo group. INTERPRETATION: Early administration of natural somatostatin continued for 120 h, combined with additional bolus injections, is more effective than placebo in the overall control of acute variceal haemorrhage in patients with cirrhosis undergoing sclerotherapy.
