- Abstract
Aims: To evaluate the results of a hepatitis B and C screening program in hospitalized COVID-19 patients., Method: Transversal prospective study conducted in two Spanish hospitals. Patients admitted from March 1st to December 31st 2020 with a diagnosis of COVID-19 were tested for markers of hepatitis B (HBsAg, anti-HBc) and C (anti-HCV, HCV RNA) infection., Results: In this period, 4662 patients with COVID-19 were admitted to our centers: 56.3% were male, median age was 76 (0-104) years. Data regarding HBV infection was available in 2915 (62.5%) patients; 253 (8.75%) were anti-HBc+ and 11 (0.38%) HBsAg+. From these, 4 patients did not have a previous diagnosis of hepatitis B, 7 received corticosteroids and one received prophylaxis. There was one HBV reactivation. Anti-HCV was available in 2895 (62%) patients; 24 (0.83%) were positive. From these, 13 patients had a previous hepatitis C diagnosis: 10 patients had been treated with SVR, one achieved spontaneous cure and 2 did not receive treatment. From the 11 previously unknown anti-VHC+patients, 10 had a negative HCV RNA. Overall, only 3 (0.10%) patients tested RNA HCV+. However, none received HCV treatment (2 older than 90 years with comorbidities, 1 died from COVID-19)., Conclusion: Screening of hepatitis C infection in hospitalized COVID-19 patients seems less useful than expected. The low prevalence of active infection after antiviral treatments and the high age of our population limit the detection of potential candidates for treatment. HBV screening should be aimed to prevent reactivation under immunosuppressive treatments., (Copyright © 2021 Elsevier España, S.L.U. All rights reserved.)

- Abstract
Introduction: Vitamin D (VD) is known to have multiple extra-skeletal health functions. There is emerging interest in exploring the relationship between vitamin D and chronic liver disease (CLD)., Objectives: To determine the prevalence of VD deficiency in patients with CLD in our setting and to assess whether VD supplementation influences plasma levels and is associated with improved liver function., Material and Methods: We conducted a study in 2 phases. First, we analysed clinical and epidemiological characteristics in 94 patients with CLD; second, different doses of calcifediol (25-OH-VD) were administered to patients with VD deficiency (<20ng/mL) and insufficiency (20-30ng/mL). Plasma concentrations and liver function (Child-Pugh and MELD) at the end of treatment were compared with baseline data., Results: Deficient or insufficient VD levels were found in 87% of the patients, with an average concentration of 18.8ng/mL. Levels were lower in patients with cirrhosis (15.9ng/mL) (P=.002) and in alcoholic liver disease. VD levels were inversely proportional to the degree of liver function: Child A (16.52ng/mL) vs C (7.75ng/mL). After VD supplementation, optimal serum levels were achieved in 94% of patients and significant improvements were observed in platelet count, albumin levels (P<.05) and functional status assessed by the Child-Pugh scale (P<.05)., Conclusion: Given the high prevalence of VD deficiency or insufficiency, the need for screening should be considered in the population with CLD. VD supplementation could be safe and effective., (Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.)

- Abstract
Background: There is an excess incidence of colorectal cancer (CRC) and mortality from this disease in the health area of Leon. The aim of the present study was to determine trends in CRC and its geographical distribution., Methods: Cases included in the Hospital Registry of Tumors of the Centro Asistencial Universitario de León from 1994-2008 and occurring in patients residing in the health area of Leon were studied. Time trends were evaluated with a Poisson regression model. To analyze geographical distribution, the smoothed relative risks (RR) of the municipalities adjusted by the Besag, York and Mollié model were calculated, and their subsequent probability of an RR>1 (PP) was calculated using Bayesian methods., Results: A total of 4,136 cases were included. Rates standardized to the European standard population ranged from 49.6 (1994-6) to 63.5 new cases per 100,000 inhabitants in men (2006-8) and from 29.6 to 33.8 in women. An annual 2% increase was found for all localizations, ranging from 1.8% in the rectum to 3.6% in the proximal colon. In all localizations, the increase was greater in men than in women. Several municipalities in the health area of Leon showed an excess risk. The geographical pattern observed was due especially to the distribution of colon cancer., Conclusions: The incidence rates observed were high and were increasing. Special attention should be paid to CRC in the health area of Leon, mainly in the municipalities with excess risk., (Copyright © 2011 Elsevier España, S.L. and AEEH y AEG. All rights reserved.)

- Abstract
Objective: Needle-knife sphincterotomy (NKS) is used to achieve biliary access when routine cannulation methods have been unsuccessful. The aim of this study was to analyze the results of NNS in patients with an inaccessible common bile duct (difficult cannulation) using standard techniques in endoscopic retrograde cholangiopancreatography and the factors associated with the success of this procedure and complications., Material and Methods: We performed a prospective study of 72 patients who underwent NKS performed by the same endoscopist (J.E.) because of difficult cannulation of the common bile duct between January 1998 and December 2004. The results were analyzed in terms of successful biliary access, whether this was achieved in one or more sessions, its possible association with the underlying disease, and the incidence and severity of complications., Results: Seventy-two NKS were performed from a total of 1062 sphincterotomies (6.7%). A total of 77.7% of the patients underwent prior implantation of a pancreatic prosthesis (NKS-PP). The final diagnosis was: choledocholithiasis (31.9%), cancer of the pancreas (16.6%), cholangiocarcinoma (13.8%), benign stenosis (8.3%), dysfunction of the sphincter of Oddi (6.9%), normal (6.9%), and miscellaneous (13.8%). Cannulation was successful in 87.5% (63/72), and was achieved in the first session in 73% (46/63). Biliary access was achieved in 72.7% of patients (16/22) with biliopancreatic neoplasms versus 94% (47/50) of those with other diagnoses (p = 0.03). Eleven patients (15.2%) presented 12 complications (16.6%) (6 pancreatitis, 4 cholangitis, 1 papillary hemorrhage, and 1 portal vein filling). The use of a pancreatic prosthesis was related to a higher success rate and significantly fewer complications (p = 0.03)., Conclusions: NKS-PP can be a safe procedure in patients with difficult cannulation of the common bile duct. The presence of biliopancreatic neoplasm is a risk factor for failure to achieve biliary access compared with other diagnoses. The complication rate was similar to that found in other studies. No cases of severe pancreatitis or perforations were found.

- Abstract
Primary leiomyosarcoma of the liver is a rare entity and fewer than 100 cases have been reported in the medical literature. Even more unusual is the association with another previous tumour. We report the case of a 84-year-old man who had been treated for a gastric non-Hodgkin lymphoma two years previously. He presented with a painful mass in the right upper abdomen. An ultrasound scan showed a large mass in the right lobe of the liver and chest radiography showed pulmonary metastases. Liver biopsy was performed and immunohistochemical analysis revealed a malignant leiomyosarcoma. We discuss this case and review the available literature.

- Abstract
Aim: To determine the degree of association between serum alpha-1-antitrypsin levels and its phenotypes as well as its clinical expression., Patients and Methods: The alpha-1-antitrypsin genotype was identified using polymerase chain reaction followed by restriction enzyme digest in 212 patients in whom serum alpha-1-antitrypsin determination had been requested. The reasons for the request, the existence of pulmonary or liver disease, clinical diagnoses and functional repercussions were analyzed., Results: Two hundred and twelve patients were evaluated (68% males; mean age: 34 20 years). In 23 patients (10.8%) a deficiency variant was found (one or two M alleles were lacking) and in 8 patients (3.8%) the genotype was ZZ. All patients with MM genotype had alpha-1-antitrypsin levels of 75 mg/dl or higher while none of the patients with ZZ genotype had levels higher than 40 ml/dl. All the patients with ZZ genotype showed alterations: 3 had pulmonary emphysema, 1 had chronic obstructive pulmonary disease and 4 had hypertransaminasemia. One patient with pulmonary emphysema had severe respiratory insufficiency while in the remaining patients with respiratory problems, respiratory insufficiency was slight or moderate. None of the patients with hypertransaminasemia showed echographic signs of portal hypertension or clinical or laboratory signs of reduced liver function., Conclusions: There is a close association between alpha-1-antitrypsin levels and the different genotypes. Consequently, in basal conditions with serum alpha-1-antitrypsin levels higher than 75 mg/dl genotyping is not required. The functional repercussions of deficiency variants in young adults is slight.

- Abstract
Aim: To determine the current status of endoscopic retrograde cholangiopancreatography (ERCP) and the effects of the introduction of magnetic resonance cholangiography (MRC) on ERCP and to evaluate the diagnostic yield of MRC since its introduction in obstructive biliary disease., Material and Methods: We performed a retrospective analysis of the ERCP carried out between January 1998 and December 2000 and of the MRC performed for suspected obstructive biliary disease from May 1999 to December 2000. When both techniques were performed, the diagnostic yield of MRC was evaluated., Results: We performed 927 ERCP. A total of 45.3% of the patients were men. Mean age was 69.2 14.6 years. Treatment was performed on 688 occasions (77%), mainly sphincterotomy (69.9%) and placement of polyethylene (21.8%) or self-expanding (9.9%) prostheses. The number of ERCP performed each year was 261, 330 and 336 in 1998, 1999 and 2000, respectively; of these 76.6%, 80% and 76.9% were therapeutic. MRC was performed in 63 patients with suspected biliary disease. In 27 of 59 patients (45.8%) MRC was sufficient for diagnosis, avoiding the need for ERCP. In the 35 patients in whom both techniques (MRC and ERCP) were performed, the diagnostic yield of MRC compared with that of ERCP was: sensitivity 100%, specificity 50%, positive predictive value 87.1%, negative predictive value 100% and overall value 89%. The cases responsible for the low specificity (all due to choledocholithiases) were analyzed and a significant time lapse was found between the performance of MRC and ERCP (range: 7-35 days) during which choledocholithiasis probably resolved spontaneously., Conclusions: a) Contrary to what could be expected, the number of ERCP seems to be increasing with a high percentage of endoscopic treatment; b) Because of its diagnostic sensitivity, MRC is the ideal technique for eliminating the need for diagnostic ERCP, thus allowing greater development of the therapeutic aspect of ERCP.

- Abstract
Aim: To determine the incidence of various digestive tumors in the health district of Leon., Patients and Methods: All digestive tumors registered in the Hospital Tumor Registry in Leon from 1993-1997 were included. Unadjusted and adjusted incidence rates of each kind of tumor, using the ICD-9 classification, were calculated., Results: A total of 9,913 cancer cases were included. Diagnosis was confirmed by the Department of Pathology in 93.4%. Of these, 25.38% originated primarily in the digestive system, which represents an unadjusted incidence of 151.73 new cases per 100,000 inhabitants/year. A total of 58.07% were male and 41.93% female. Colon cancer was the most frequent (31.5%), followed by gastric cancer (25.7%) and rectal cancer (20.3%). The highest incidence, both unadjusted and adjusted, was in colon cancer (52.8 and 25.9) followed by gastric cancer (47.4 and 24.3) and rectal cancer (36.1 and 18.3, all they 10(5)/year., Conclusions: Incidence of digestive cancer in Leon is very high and that of colorectal cancer is higher than in any other region in Spain. This is only partly due to the marked aging of our population.

- Abstract
Multiple focal nodular hyperplasia is an uncommon benign liver tumor although its incidence has been increasing in the last few years. A case of focal nodular hyperplasia in a young woman is described, which was discovered in infancy and which presented two nodules in each lobe. The diagnosis was subsequently confirmed by large surgical biopsy. Conservative therapy was given for 16 years during which time there was progressive tumor growth, increase of pain and cholestatic enzymes. The unusual presentation this benign lesion may have, a strategy for its diagnosis and the generally conservative management that is currently favored are discussed.

- Abstract
We present a 68 year old male with alcoholic cirrhosis that was admitted with abdominal pain and fever. Hepatocarcinoma and spontaneous bacterial peritonitis by Listeria monocytogenes was diagnosed. The patient was treated with ampicillin and tobramycin during 25 days following a favorable course although ascitic fluid remained abnormal during 21 days. It is noted the rarity of Listeria as a cause of bacterial peritonitis in cirrhotic patients although they are immunodeficient. It is also important to establish the etiological origin because standard treatment of spontaneous bacterial peritonitis is cefotaxime and Listeria is resistant to this antibiotic. The 66% of spontaneous bacterial peritonitis secondary to Listeria monocytogenes infection in cirrhotic patients has been reported in Spain and this might be due to a higher incidence of human listeriosis in this country.
