Abstract
BACKGROUND Hepatitis C virus (HCV) translation is initiated in a cap-independent manner by an internal ribosome entry site (IRES) located within the 5' untranslated region (5'UTR). Sequence changes in this region could affect translation efficiency and presumably viral replication. AIM To determine translation efficiency of 5'UTR variants developing during post-transfusion hepatitis C in two immunocompetent subjects and in two immunosuppressed liver recipients with recurrent HCV. METHODS Sequential samples were screened for 5'UTR changes by single-strand conformation polymorphism followed by cloning and sequencing whenever band pattern suggested sequence changes. 5'UTR variants were tested for IRES activity using a bicistronic dual luciferase expression plasmid transfected into HepG2 and Huh7 cell-lines. RESULTS In the transfused patients, translation efficiency of 5'UTR variants from early post-transfusion samples was 5.1- to 13.7-fold higher than that of predominant variants found in late follow-up samples. Post-transplant variants in the other two patients had 2.6- to 5.9-fold higher translation efficiency than those present only in pretransplant samples. CONCLUSION In the immunocompetent host there may be selection of low translation efficiency HCV variants over the course of infection. However, in immunosuppressed subjects the opposite seems to be true as low translation efficiency variants are superseded by high translation efficiency variants.

Abstract
BACKGROUND Inflammatory bowel disease impairs patients' perception of health and has a negative impact on health-related quality of life (HRQOL). Most studies include patients from a single hospital. This may bias limit results through the use of small patient samples and/or samples within a restricted disease spectrum. METHODS HRQOL was measured in patients with ulcerative colitis (UC) and Crohn's disease (CD) from 9 hospitals located in different geographical areas in Spain using 2 questionnaires: the Spanish version of the Inflammatory Bowel Disease Questionnaire (IBDQ) and the EuroQol. Results are expressed as medians. RESULTS The study included 1156 patients (528 patients with UC and 628 with CD; median age, 35 yr; slight predominance of women, 617 versus 539). HRQOL worsened in parallel with disease severity to a similar extent in both UC (IBDQ scores of 6.1, 4.7, and 4.0 for the 3 disease severity groups, respectively) and CD (IBDQ scores of 6.1, 5.0, and 4.1, respectively). A similar inverse relation between clinical activity and quality of life was observed when EuroQol preference values were used. All 5 dimensions of the IBDQ showed significantly lower scores in patients with active UC and CD than in patients in remission. The pattern of scores by IBDQ dimensions differed between patients in relapse (who scored worse on the digestive symptoms dimension) and patients in remission. Variables related with disease activity, time of evolution since diagnosis and female sex, were significantly associated with having a worse perception of HRQOL. The type of disease or geographical area of residence did not influence results on the IBDQ. CONCLUSIONS UC and CD impair patients' HRQOL, and the degree of impairment depends on disease activity but is independent of the type of disease and place of residence.

Abstract
OBJECTIVE to determine the clinical, microbiological, diagnostic and therapeutic characteristics of pyogenic liver abscesses of bacterial origin. METHODS retrospective analysis of pyogenic liver abscesses diagnosed at the Aránzazu Hospital in San Sebastián (northern Spain) between 1989 and 1998. RESULTS we studied 45 patients with pyogenic liver abscesses of bacterial origin (30 men, 15 women, mean age 61 years 11 months). The site of the liver abscess was biliary in 28.9% of the patients, portal in 11.1%, and unknown in 33.3%. Elevated erythrocyte sedimentation rate (95.5%), leukocytosis (86.7%) and fever (82.2%) were the most frequent clinical and laboratory findings. The abscesses were solitary in 55. 5% of the patients. Echography was diagnostic in 68.4% of patients, and computed tomography was diagnostic in 100%. Cultures of pus from the abscess and blood were positive in 77.1% and 50% respectively. Of the abscesses diagnosed as being of bacterial origin, 44.4% involved multiple organisms. Escherichia coli and Streptococcus milleri were the germs isolated most frequently. Percutaneous drainage was done in 22 patients (48.9%), with satisfactory results in 18. Overall mortality related with abscesses was 15.5%. CONCLUSIONS the clinical presentation of pyogenic liver abscess did not vary during the study period. Computed tomography is fundamental for diagnosis and treatment. Percutaneous drainage associated with early antibiotic therapy is the treatment of choice.

Abstract
Autoimmune hepatitis is a necro-inflammatory disease of unknown etiology. An acute or fulminant presentation is rare. We report a 18-year-old man presented with acute variceal hemorrhage. The patient was treated with endoscopic sclerotherapy, somatostatin, balloon tamponade and TIPS. The patient died within a week of massive bleeding and hepatic failure. This patient's history strongly suggests that autoimmune hepatitis can be presented as fulminant hemorrhage. The importance of diagnosis and treatment is emphasized to improve prognosis.

Abstract
Bronchogenic lung carcinoma, melanoma and breast cancer are the neoplasms which have most frequently been reported to metastasize to the stomach. These lesions are usually located on the fundus and on the upper part of the gastric body. They are usually asymptomatic with the diagnosis being made at necropsy. We present a patient who developed gastrointestinal bleeding as the first symptom of squamous lung cancer secondary to a gastric metastasis.

Abstract
In order to analyse the prevalence and significance of cryoglobulinaemia in patients with chronic hepatitis C virus (HCV) infection and the possible relationship of cryoglobulinaemia with the genotypes of HCV, we studied 89 patients with chronic HCV infection, 42 healthy controls and 22 patients with alcoholic cirrhosis. The patients with HCV were divided into three different groups according to the presence of cirrhosis and alanine aminotransferase levels. Moreover, in 20 patients with HCV and cryoglobulinaemia, HCV RNA sequences were quantified in serum and in cryoprecipitate. Cryoglobulins were detected more frequently in patients with chronic HCV infection than in healthy controls (42.6% vs. 4.7%; P<0.0001). Cryoglobulins were present in 68.4% of patients with HCV-related cirrhosis, which was nearly twice the figure in noncirrhotic HCV-infected patients and alcoholic cirrhotic patients. There were no differences in age, sex, aminotransferase levels or HCV genotype distribution in HCV-infected patients with or without cryoglobulinaemia. Only 13% of patients with chronic HCV infection and cryoglobulins showed symptoms of cryoglobulinaemia. There was a linear association between HCV RNA concentration in sera and in cryoprecipitates (P<0.0005). Patients with chronic HCV infection had a high prevalence of cryoglobulinaemia, especially in advanced forms of the disease, but clinical findings are few. There was no relationship with the genotype of HCV. The presence of HCV RNA in cryoprecipitates supported the hypothesis on the aetiological role of HCV in mixed cryoglobulinaemia.

Abstract
OBJECTIVE We aimed to investigate the modifications of HCV RNA (genomic and antigenomic strands) in peripheral blood mononuclear cells (PBMCs) of long-term responder patients to alpha-interferon therapy, and their usefulness as criteria of definitive HCV eradication. METHODS We studied 10 patients with chronic hepatitis C with > 1 yr of sustained response after alpha-interferon therapy (normal alanine aminotransferase [ALT] and negative serum HCV RNA). Serum HCV RNA and genotyping were determined. Approximately 2 and 4 yr after completion of treatment we investigated the presence of HCV RNA (genomic and antigenomic strands) in PBMCs. Eight of 10 patients were rebiopsed 2 yr after discontinuation of treatment. RESULTS The mean follow-up was 46.6 +/- 4.6 months (range, 39-51 months). In this period, all patients remained in sustained response. In the first determination, all patients had HCV RNA genomic strands and two patients had antigenomic strands detectable in PBMCs. Two years later only two patients had genomic and none had antigenomic strands detectable. After 4 yr of sustained response, eight of 10 patients lost HCV RNA from PBMCs. CONCLUSIONS In the long-term follow-up, the majority of patients with chronic hepatitis C with sustained response after alpha-interferon therapy progressively lost HCV RNA from PBMCs. This determination in PBMCs is not a predictor of response.

Abstract
OBJECTIVE To present the clinical, biological, radiologic and cholangiographic findings in patients with clinical suspicion of AIDS associated cholangiopathy in our hospital. PATIENTS AND METHODS We have revised the clinical charts of 10 patients admitted in our hospital from 1991 to 1995. RESULTS Ultrasonography and/or abdominal CT were carried out on all the patients. Biliary tract dilatation was observed in 11 cases. From the 12 ERCP, biliary tract was fulfilled in 11. In 5 cases papillary stenosis was diagnosed, sclerosing cholangitis in 2, normal biliary tract in 3 and acute cholangitis in one case. Sphincterotomy was done in 5 patients, with clinical improvement. In one case, another sphincterotomy was needed because of reestenosis. CONCLUSIONS ERCP is very important in the diagnosis of AIDS associated cholangiopathy. Endoscopic sphincterotomy relieves abdominal pain in these patients. Cholangiopathy occurs in very immunocompromised HIV positive patients. Survival is very short.

Abstract
Helicobacter pylori is one of the most common bacterial infections worldwide. To evaluate the prevalence of this infection in Gipuzkoa (Basque Country, Spain) we studied the presence of antibodies against Helicobacter pylori (HPAb) using a second-generation EIA (Cobas Core). The study was performed on two groups of subjects: a middle-class group, 2-78 years-old (n = 1335) and a group of slum dwellers, 2-15 years-old (n = 89). In the middle-class group the prevalence of HPAb in children under 6 was 3.1% (3/96); the prevalence was significantly greater in older compared to younger age groups, reaching 84.3% (102/121) in adults 50-59 years. The geometric mean of the titer in seropositive subjects was also greater in older age groups. By logistic regression analysis the prevalence of HPAb was associated with age, educational level and geographic origin but not with sex, smoking, alcohol consumption, or use of nonsteroid anti-inflammatory drugs. The prevalence of HPAb was much higher in the slum-dwelling group 2-15 years-old (55.5% of children 2-5 years-old). The results indicate that H. pylori infection was more common in adult people from our geographic region than in those from other developed countries and show that socioeconomically deprived children constitute at present a group at high risk of acquiring infection in our region.

Hepatic rupture is an unusual complication of hepatic amyloidosis. We report the case of a 59-yr-old man with a subcapsular hematoma of the liver with hepatic rupture secondary to amyloidosis. The patient died during the surgery. The etiology, pathology, diagnosis, and treatment of this complication are discussed. Previously reported cases of subcapsular hematoma of the liver secondary to amyloidosis are reviewed. This knowledge and an awareness of the possible diagnosis will help to decrease the high mortality rate associated with this complication.

Abstract
UNLABELLED We studied the efficacy of local injections of botulinum toxin in the treatment of patients with achalasia. Four patients diagnosed of achalasia using manometric, radiologic and endoscopic criteria, were treated with botulinum toxin (80 U) injected directly into lower esophageal sphincter (LES), via a sclerotherapy injector. Response to treatment was assessed by changes in symptom scores and LES pressure. All determinations were repeated after 10, 30, 90, 120 and 180 days of treatment. The patients improved after the initial injection. This improvement was accompanied by improved relaxation of the LES. Two patients relapsed after 30 and 65 days and the other two patients remained symptom-free 5 months after treatment. CONCLUSION Botulinum toxin is probably a safe and effective alternative for the treatment of achalasia and should be considered in patients in whom pneumatic dilation has failed or who are poor surgical candidates. Long-term evaluation of the safety and efficacy of botulinum toxin in the treatment of achalasia is required.

Abstract
The closely interrelated Lewis, secretor, and ABO phenotypes have long been linked to the risk of peptic ulcers and gastric cancer and may modulate the interaction between Helicobacter pylori and the gastric surface epithelium. We explored the association between the expression of sulfomucins in gastric intestinal metaplasia, a known marker of preneoplastic progression, and the expression of Lewis, secretor, and ABO phenotypes, in 523 subjects from Nariño, Colombia, and 856 subjects from northern Spain. In both study populations, Lewis (a+/b-) and nonsecretor phenotypes showed a significant positive association with the expression of sulfomucins (odds ratios, 2.4 and 2.6, respectively).

Abstract
The genotype of HCV was determined in 161 chronic HCV-infected patients. The patients were classified into three groups on the basis of the origin of the HCV infection: 50 patients had a history of intravenous drug use (IVDU) but no HIV infection; 41 patients had received blood transfusions, and 70 patients had no known exposure. The distribution of HCV genotypes was associated with the origin of infection and age of patients: genotype 1b was predominant among patients who had received blood transfusions and those without evidence of parenteral exposure (84.6% and 67.7%, respectively), whereas genotype 3a was present in 65.3% of IVDUs. Patients with genotype 1b were older than those with genotypes 1a or 3a: 50.3 +/- 12 vs. 34.1 +/- 9.9 and 31 +/- 5.4 years, respectively. These findings suggest that the pattern of HCV genotypes in our region is changing and that genotype 1b may be substituted by 3a as the dominant genotype in the future.

Abstract
The Peutz-Jeghers syndrome is characterized by gastrointestinal polyposis and mucocutaneous melanin pigmentation. Between the complications are the appearance of gastrointestinal neoplasms. There is an increasing evidence suggesting the hamartoma-adenoma-carcinoma sequence in Peutz-Jeghers syndrome. We present a 32-years-old man with Peutz-Jeghers syndrome who developed an adenocarcinoma arising in a gastric hamartomatous polyp. We discuss the risk to develop gastrointestinal neoplasms and the necessity for periodic surveillance.

Abstract
A multicentric double-blind trial comparing 600 mg/d of Zinc Acexamate (ACZ) and 40 mg/d of Famotidine (FMT) in the short term treatment of acute duodenal ulcer included 199 patients, diagnosed by endoscopy. One-hundred and five patients received ACZ and 94 FMT, during four weeks. A clinical control took place at two weeks and a second clinical and endoscopic control at the end of the treatment (4 weeks). Complete cicatrization of the ulcer was observed in 56.5% of patients on ACZ and in 69.5% of patients of FMT (N.S.). A reduction of more than 50% of the ulcer diameter was recorded in 78.8% of the ACZ group and in 79.9% of the FMT group. Alcohol and smoking did not influence the results. Both treatments were equally effective in the disappearance of symptoms. The incidence of adverse reactions was very low in both groups (< 5%) and no patient dropped from the trial for this reason. In conclusion, a dosage of 600 mg/d of ACZ has shown to be as effective as 40 mg/d of FMT in the healing of duodenal ulcer.
