Abstract
PURPOSE To evaluate the safety and efficacy of selective internal radiation therapy (SIRT) in combination with a PD-1 inhibitor in patients with unresectable hepatocellular carcinoma (uHCC) and liver-only disease ineligible for chemoembolization. PATIENTS AND METHODS NASIR-HCC is a single-arm, multicenter, open-label, phase 2 trial that recruited from 2017 to 2019 patients who were naïve to immunotherapy and had tumors in the BCLC B2 substage (single or multiple tumors beyond the up-to-7 rule), or unilobar tumors with segmental or lobar portal vein invasion (PVI); no extrahepatic spread; and preserved liver function. Patients received SIRT followed 3 weeks later by nivolumab (240 mg every 2 weeks) for up to 24 doses or until disease progression or unacceptable toxicity. Safety was the primary endpoint. Secondary objectives included objective response rate (ORR), time to progression (TTP), and overall survival (OS). RESULTS 42 patients received SIRT (31 BCLC-B2, 11 with PVI) and were followed for a median of 22.2 months. 27 patients discontinued and 1 never received Nivolumab. 41 patients had any-grade adverse events (AE) and 21 had serious AEs (SAE). Treatment-related AEs and SAEs grade 3-4 occurred in 8 and 5 patients, respectively. Using RECIST 1.1 criteria, ORR reported by investigators was 41.5% (95% CI 26.3% to 57.9%). Four patients were downstaged to partial hepatectomy. Median TTP was 8.8 months (95% CI 7.0 to 10.5) and median OS was 20.9 months (95% CI 17.7 to 24.1). CONCLUSIONS The combination of SIRT and nivolumab has shown an acceptable safety profile and signs of antitumor activity in the treatment of patients with uHCC that were fit for SIRT. TRIAL REGISTRATION NUMBER NCT03380130.

Abstract
A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) α-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of "extra-target" RAS suggests the need for RAS screening in all three DAA target regions.

Abstract
Treatment guidelines differ in their recommendation to determine baseline resistance associated substitutions (RAS) before starting a first-line treatment with direct-acting antivirals (DAAs). Here we analyze the efficacy of DAA treatment with baseline RAS information. We conducted a prospective study involving 23 centers collaborating in the GEHEP-004 DAA resistance cohort. Baseline NS5A and NS3 RASs were studied by Sanger sequencing. After issuing a comprehensive resistance report, the treating physician decided the therapy, duration and ribavirin use. Sustained virological response (SVR12) data are available in 275 patients. Baseline NS5A RAS prevalence was between 4.3% and 26.8% according to genotype, and NS3 RASs prevalence (GT1a) was 6.3%. Overall, SVR12 was 97.8%. Amongst HCV-GT1a patients, 75.0% had >800,000 IU/ml and most of those that started grazoprevir/elbasvir were treated for 12 weeks. In genotype 3, NS5A Y93H was detected in 9 patients. 42.8% of the HCV-GT3 patients that started sofosbuvir/velpatasvir included ribavirin, although only 14.7% carried Y93H. The efficacy of baseline resistance-guided treatment in our cohort has been high across the most prevalent HCV genotypes in Spain. The duration of the grazoprevir/elbasvir treatment adhered mostly to AASLD/IDSA recommendations. In cirrhotic patients infected with GT-3 there has been a high use of ribavirin.

Abstract
BackgroundReducing the burden of the hepatitis C virus (HCV) requires large-scale deployment of intervention programmes, which can be informed by the dynamic pattern of HCV spread. In Spain, ongoing transmission of HCV is mostly fuelled by people who inject drugs (PWID) infected with subtype 1a (HCV1a).AimOur aim was to map how infections spread within and between populations, which could help formulate more effective intervention programmes to halt the HCV1a epidemic in Spain.MethodsEpidemiological links between HCV1a viruses from a convenience sample of 283 patients in Spain, mostly PWID, collected between 2014 and 2016, and 1,317, 1,291 and 1,009 samples collected abroad between 1989 and 2016 were reconstructed using sequences covering the NS3, NS5A and NS5B genes. To efficiently do so, fast maximum likelihood-based tree estimation was coupled to a flexible Bayesian discrete phylogeographic inference method.ResultsThe transmission network structure of the Spanish HCV1a epidemic was shaped by continuous seeding of HCV1a into Spain, almost exclusively from North America and European countries. The latter became increasingly relevant and have dominated in recent times. Export from Spain to other countries in Europe was also strongly supported, although Spain was a net sink for European HCV1a lineages. Spatial reconstructions showed that the epidemic in Spain is diffuse, without large, dominant within-country networks.ConclusionTo boost the effectiveness of local intervention efforts, concerted supra-national strategies to control HCV1a transmission are needed, with a strong focus on the most important drivers of ongoing transmission, i.e. PWID and other high-risk populations.

Abstract
Neutrophil-to-lymphocyte ratio (NLR) is considered a prognostic factor in patients with hepatocellular carcinoma (HCC). Our aim is to investigate the prognostic significance of NLR in patients with HCC treated with sorafenib. Results Median follow-up time was 7 months. Patients were mostly in the intermediate (27.3%) or advanced (72.7%) BCLC stages, 38.6% had vascular invasion and 27.5% extrahepatic disease. A large proportion (38.9%) had been previously treated with TACE. Liver function was preserved: 65.8% were classed as Child A. Median overall survival was 7.7 months (95% CI: 5.8-9.6). In univariate analysis, vascular invasion (P = 0.004), ECOG-PS ≥ 1 (P < 0.001), high bilirubin (P < 0.001), clinical ascites (P = 0.036), BCLC stage (P = 0.004), no previous TACE (P = 0.041) and NRL ≥ 2.3 (P = 0.005) were predictors of poor survival. Skin toxicity (P = 0.039) or hypertension (P = 0.033) during treatment were related to better survival. In multivariate analysis NLR ≥ 2.3 [HR 1.72 (95% CI: 1.03-2.71)], hyperbilirubinemia [HR 3.42 (95% CI: 1.87-6.25)] and ECOG-PS ≥ 1 [HR 1.97 (95% CI: 1.19-3.26)] were found as independent indicators of poor overall survival. Dermatologic adverse effects were an indicator of good overall survival [HR 0.59 (95% CI: 0.38-0.92)]. Material and Methods One hundred and fifty-four consecutive HCC patients treated with sorafenib in four different Spanish hospitals between August 2005 and October 2013 were analysed. Clinical, laboratory, and tumour features were obtained. Survival was calculated from the moment sorafenib treatment was initiated. Log-rank and Cox regression were used to analyse the ability of NLR to predict survival. Conclusions NLR is an independent prognostic indicator for overall survival in HCC patients treated with sorafenib.

Abstract
AIM: To investigate if the clinical efficacy of granulocytes and monocytes by adsorption (GMA) is associated with an increased frequency of peripheral regulatory T cells (Tregs), as these cells have proven to be successful in suppressing inflammatory bowel disease (IBD) in animal models.
METHODS: We report four cases of corticosteroid-dependent ulcerative colitis (UC) and two Crohn’s disease (CD) cases with severe cutaneous lesions who received GMA therapy. The frequency of CD4+ CD25high (Tregs) in peripheral blood was analyzed by flow cytometry and the expression of FoxP3 and TGF beta in purified CD4+ T cells was determined by real time PCR prior to and one month after the last apheresis session, and at the time of endoscopic and clinical assessing.
RESULTS: Increased expression of Fox P3 mRNA was found in all five patients who responded to cytapheresis with remission of clinical symptoms, mucosal inflammation and cutaneous lesions, and an increased frequency of circulating Tregs was found in four patients. These changes were not observed in the patient with UC who did no respond to GMA. Variations in TGF-β (mRNA) did not parallel that of FoxP3 mRNA.
CONCLUSION: The clinical efficacy of GMA on IBD and related extra intestinal manifestations was associated with an expansion of circulating CD4+ CD25+ Tregs and higher expression of FoxP3 in CD4+ T cells. Accordingly, an elevated CD4+ CD25+ FoxP3 may be a valuable index of remission in patients with IBD and other chronic relapsing-remitting inflammatory conditions during treatment with GMA.

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
Bacteriemia is a frequent infection in patients with hepatic cirrhosis, which is associated with a high mortality. Spontaneous bacteriemia is generally caused by gramnegative bacilli. We present an episode of Salmonella hadar's spontaneous bacteriemia in a patient with cirrhosis of the liver and transjugular intrahepatic portosystemic shunt. The role of the prosthesis in the pathogenesis of bacteriemia in hepatic cirrhosis is discussed.

Abstract
We report two cases of acute hepatotoxicity after treatment with amoxicillin-clavulanic. Viral hepatitis serology and autoantibodies were negative. Biliary tree obstruction and other etiologies were excluded. After discontinuation of the drug the evolution was favorable with clinical improvement and normalization of liver tests. Liver biopsy made in one patient showed cholestasic hepatitis with hepatocellular necrosis and other patient was treated with ursodeoxycholic. Also, we analyse potential utility of ursodeoxycholic acid administration in toxic cholestasis.

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.

Abstract
Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The secondary gastrointestinal disturbances are not well recognized. Two cases of myotonic dystrophy in a 51-year-old and 39-year-old woman with gastrointestinal symptoms disturbances are reported. One patient presented motor dysfunction in the colon and esophagus, organoaxial gastric volvulus and cholestasis. The second patient developed an acute colonic pseudo-obstruction. The patient improved with cisapride. The digestive manifestations of myotonic dystrophy and the treatment are reviewed.

Abstract
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.

Viral causes, autoimmune hepatitis, biliary tree obstruction and other risk factors were excluded. After discontinuation of the drug evolution was favorable and clinical signs and hepatic laboratory tests became normal in both cases. We also review the literature about hepatotoxicity induced by anti-Staphylococci semisynthetic penicillins.

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).

Herpetic esophageal primary infection is not a common event in immunocompetent patients. The case of a 27-year-old immunocompetent woman who developed herpetic esophagitis involving the whole esophagus as a manifestation of primary herpetic infection is presented. The endoscopic appearance initially suggested esophageal candidiasis, which is not an exceptional event.

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.
