Primary gastric melanoma is an exceptional tumour with less than 20 cases described in the literature, as its origin is not entirely clear as the presence of melanocytes in the stomach has not been demonstrated. Symptomatology is non-specific, which prevents its early detection, and it is diagnosed in late stages. We present the case of a patient who was admitted to our hospital for vomiting in coffee grounds with analytical and haemodynamic repercussions. Urgent gastroscopy revealed a gastric lesion suspicious for malignancy, which was histologically confirmed as gastric melanoma. The therapeutic approach to these tumours is complex and they have a very poor prognosis.

Hepatitis C virus (HCV) one-step diagnosis improves recovery in patients with active infection. However, patients with previous anti-HCV+ may be excluded. We aimed to identify and retrieve non-referred or lost-to-follow-up HCV-infected patients. All anti-HCV+ patients seen in our hospital between 2013 and 2018 were included. In the first phase, we identified anti-HCV+ patients who were not referred to the Gastroenterology Unit (GU) or lost-to-follow-up. In the second phase, recovered patients were invited for a one-step visit for liver evaluation. A total of 1330 anti-HCV+ patients were included: 21.7% had not been referred to GU, and 23.1% were lost-to-follow-up. In the second phase, 49.6% of patients were contacted, and 92.8% attended a medical consultation: 62.7% had active infection, 92.2% were treated, and 86.5% achieved SVR (ITT). We concluded that screening microbiological data and referring unidentified patients with active HCV infection directly to specialists is an effective tool in achieving HCV microelimination.

Hereditary familial hypobetalipoproteinemia (FHBL) is a syndrome caused by variants in the APOB gene, that cause a defect in the secretion and mobilization of liver lipids to peripheral tissues, associated with the synthesis of truncated ApoB100 apolipoproteins. This condition causes significant reduction in total cholesterol (TC), low-density lipoproteins (LDL), very low-density proteins (VLDL) and serum triglyceride levels, with unchanged high-density lipoprotein (HDL) cholesterol levels. Herein we present the case of a middle-aged woman diagnosed with FHBL and hepatic steatosis, heterozygous for c.4698CA; (p.Tyr1566Ter) variant in APOB. The variant presented herein showed high expressiveness in the two generations of individuals analyzed and has not yet being described in the medical literature. Early diagnosis and screening for associated metabolic comorbidities such as metabolic fatty liver disease and its subsequent progression to fibrosis are the two main goals in the treatment of this condition, in order to prevent medium to long term potential complications.

We present the case of a 71-year-old male with a medical history of hypertension, dyslipidemia, and acute myocardial infarction in 2007 who was taking low-dose aspirin and bemiparin 3500 IU every 24 hours. He was admitted to the Urology Service with recurrent hematuria 14 days after radical prostatectomy, which ceased after continuous bladder irrigation.

several barriers remain in the hepatitis C care cascade, which need to be removed in order to eliminate chronic hepatitis C. These barriers include deficiencies in screening and confirmatory diagnosis as well as difficulties in accessing treatment.to identify factors associated with the non-referral of patients with positive hepatitis C virus (HCV) antibodies and to identify factors associated with loss of follow-up or non-attendance of these patients to specialist consultation after referral.observational and retrospective single-center-study, including all positive HCV serology tests performed between January 2013 and May 2018, in the Virgen Macarena health area (Seville, Spain) before implementing the one-step diagnosis. Non-referred patients and patients who were lost to follow-up after being referred were identified.a total of 54 (77.4 %) patients diagnosed in Primary Care (PC) and 54 (22.2 %) from hospital specialists were not referred (p0.001). Predictors for non-referral were: stay in prison/institutionalization (p = 0.04), suffering chronic obstructive pulmonary disease (COPD) (p = 0.07), a normal AST value (p = 0.034) or test requested by Primary Care physician (PCP) (p = 0.004). Patients referred from PC were more likely to be lost to follow-up than those referred from hospital specialists (p0.001). Predictors of follow-up loss included: opioid replacement therapy (p = 0.034), absence of high blood pressure (p = 0.039) and test requested by PCP (p = 0.049).a high percentage of patients with positive HCV serology were not referred or were lost to follow-up, mainly those belonging to high risk social groups or those with associated comorbidities. Patients with average values of transaminases or those diagnosed in PC were also less frequently referred.

Background: vedolizumab is an α4β7 integrin antagonist. The aim of this study was to evaluate the clinical response and remission rates with vedolizumab. Methods: this was a retrospective study of inflammatory bowel disease (IBD) patients who received vedolizumab between 2016 and 2019. Response and remission rates were analyzed at three, six, 12, 18 and 24 months after induction. Results: fifty-five patients were included. Clinical remission rates in CD and UC at three, six, 12, 18 and 24 months were 19.35 %, 26.67 %, 30.43 %, 30 %, 38.89 % and 29.17 %, 26.09 %, 19.05 %, 26.67 % and 20 %, respectively. Conclusions: vedolizumab is effective for induction and maintenance of clinical remission, both in Crohn’s disease and ulcerative colitis.

[Introduction] patients with advanced chronic liver disease (CLD) may be at an increased risk of a severe course due to cirrhosis-associated immune dysfunction. The aim of this study was to determine the prevalence of CLD in COVID-19 patients and to analyze the course of the infection, compared with patients with non-liver disease., [Materials and methods] this was a retrospective single center study of all patients with a positive SARS-CoV-2 polymerase chain reaction (PCR) test from March 23rd to April 30th, 2020. Clinical and biochemical data of patients with and without CLD and COVID-19 were collected from the medical records., [Result] four hundred and forty-seven patients with a SARS-CoV-2 positive PCR were included, 6.3 % had CLD; 69.7 % of patients with CLD were male, with a median age of 65.5 years and active alcohol consumption and smoking; 75 % had non-advanced liver fibrosis and most had non-alcoholic fatty liver disease (NAFLD). The hospital admission rate (92.9 % vs 47.7 %, p < 0.001), concomitant comorbidities (diabetes 38.5 vs 16.5 %, p = 0.011; obesity 30.8 vs 8.5 %, p = 0.033; cancer 23.1 vs 5 %, p = 0.027; and chronic obstructive pulmonary disease (COPD) 19.2 vs 9 %, p = 0.009) and concomitant antibiotics treatment (19.3 vs 5 %, p = 0.018) were higher in patients with CLD than in those without CLD. In-patient hospital mortality rates were similar in both groups (30.8 vs 19.6 %, p = 0.289). The presence of CLD was not associated with mortality (OR = 1.06; 95 % CI = 0.35-3.18; p = 0.924). However, patients with CLD and COVID-19 who were male, obese or under concomitant antibiotic treatment had the highest risk of mortality according to the univariate analysis., [Conclusion] patients with CLD had a higher risk of hospital admission, with worse outcomes during the COVID-19 infection associated to other concomitant comorbidities and a suspicion of bacterial co-infection., Financial support statement: this study was partly supported by Plan Nacional de I+D+i 2013-2016 and Instituto de Salud Carlos III, Subdirección General de Redes y Centros de Investigación Cooperativa, Spanish Ministry of Science and Innovation, Spanish Network for Research in Infectious Diseases (REIPI RD16/0016/0001), co-financed by the European Development Regional Fund “A way to achieve Europe”, Operative Program Intelligence Growth 2014-2020.
