Sweet's syndrome or acute febrile neutrophilic dermatosis (SS) is characterized by the sudden onset of painful erythematous lesions (papules, nodules, and plaques) together with fever and neutrophilia. The lesions are typically located on hands, arms, upper trunk, neck and face, showing an asymmetric distribution. Acute phase reactants are usually elevated and dermal infiltration of neutrophils without vasculitis is seen on skin biopsies. It is considered as a marker of systemic disease in over half of the cases, and is associated with infections, inflammatory bowel disease, autoimmune connective tissue disorders and various neoplasias. Its association with Crohn's disease (CD) is unusual and it appears mainly in association with colonic involvement. Fewer than 50 cases have been published in the medical literature since its first description in 1964, some concurrent with the first episode of CD. We present two patients with Crohn's disease and Sweet's syndrome diagnosed in our department at the time of CD diagnosis, as well as their response to treatment, subsequent course of the disease, and a review of the scientific literature.El síndrome de Sweet o dermatosis neutrofílica febril aguda (SS) se caracteriza por la aparición brusca de lesiones eritematosas, (pápulas, nódulos y placas) dolorosas, junto con fiebre y neutrofilia, siendo de presentación poco frecuente. Las lesiones se localizan preferentemente en manos, brazos, parte superior del tronco, cuello y cara, con distribución asimétrica. Suele haber elevación de reactantes de fase aguda y en las biopsias cutáneas se identifica una infiltración dérmica de neutrófilos sin vasculitis. Se considera un marcador de enfermedad sistémica en más de la mitad de los casos, asociándose a infecciones, enfermedad inflamatoria intestinal, conectivopatías autoinmunes y diversas neoplasias. Su asociación con la enfermedad de Crohn (EC) es poco habitual, asociado sobre todo a afectación colónica. Se han publicado menos de 50 casos en la literatura médica desde su primera descripción en 1964, algunos de ellos simultáneos con el primer brote de la EC. Presentamos dos pacientes con enfermedad de Crohn y síndrome de Sweet diagnosticados en nuestro servicio en el momento del diagnóstico de la EC, así como su respuesta al tratamiento, evolución posterior y revisión de la literatura científica.

Background: Data on the true prevalence of hepatitis C virus (HCV) infection in the general population is essential. We evaluated a program implementing free universal HCV screening using a non-invasive point-of-care test (POCT) (OraQuick-HCV rapid test) in oral fluid in an urban area in Valencia, South-Eastern Spain., Methods: A cross-sectional study was performed during 2015-2017. Free HCV screening was offered by regular mail to 11,500 individuals aged 18 and over, randomly selected from all census residents in the Health Department. All responding participants filled in a questionnaire about HCV infection risk factors and were tested in their tertiary Hospital. In those with a positive POCT, results were confirmed by enzyme-immunoassay and HCV-RNA., Results: 1,206 persons agreed to participate (response rate: 11.16%). HCV antibodies were detected in 19 (1.60%) cases (age-sex standardized rate: 1.31%; 95%CI: 0.82-2.07), but only 8 showed positive HCV-RNA (age-sex standardized rate: 0.56%; 95%CI: 0.28-1.14). The majority (89%) of the cases were born before 1965 and 74% had at least one known risk factor for HCV infection. All anti-HCV positive individuals were already aware of their infection, and no undiagnosed cases were detected. The performance of the POCT was excellent for detecting active infection., Conclusions: These preliminary data suggest that HCV population screening with a POCT is feasible but, in our setting, mailing recruiting is not effective (11% response rate). The low prevalence of HCV antibodies and active infection in the participant population (with no new diagnoses made) suggests that, in our setting, underdiagnosis may be uncommon., Competing Interests: M.

Background: Therapies for hepatitis C virus (HCV) infection have revolutionized the treatment of patients with chronic HCV infection. The effect of these therapies on the epidemiology of liver transplantation (LT) has yet to be elucidated., Aim: To establish whether the indications for LT have changed as a result of the introduction of new therapies for HCV., Materials and Methods: We conducted a retrospective study based on a prospectively maintained registry of patients who undergo LT at La Fe Hospital in Valencia from 1997 to 2016. An analysis of outcome measures over time stratified by LT indications was performed., Results: From January 1997 to December 2016, 2379 patients were listed for LT. Of these, 1113 (47%) were listed for HCV cirrhosis±hepatocellular carcinoma (HCC). This percentage varied significantly over time declining from 48.8% in the 1997-2009 initial period (IFN-based regimens) to 33% in the 2014-2016 final period (DAAs regimens) (P = .03). However, during that period, the proportion of those included in the waiting list (WL) due to HCV-HCC increased significantly (P = .001). In addition, among HCV-positive waitlisted patients with decompensated cirrhosis without HCC, the proportion of those with an HCV-alcohol mixed etiology also increased significantly over time (P = .001). Of all HCV-positive waitlisted patients, 203 were eventually removed from the WL due to either clinical improvement (n = 77) or more frequently worsening/death (n = 126)., Conclusions: The proportion of patients wait-listed for LT for decompensated HCV cirrhosis has significantly decreased over time. These changes are possibly related to the large-scale use of direct-acting antivirals., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: A reliable population screening strategy for hepatitis C virus (HCV) infection may be based in easy-to-use point-of-care (POC) tests for HCV antibodies, but validation data is needed before their potential widespread use in primary care or outreach practice. Besides, the sensitivity of these POC tests in patients with spontaneous or treatment-induced viral clearance is unknown., Objectives: To test the performance of a non-invasive POC anti-HCV test (OraQuick HCV rapid test) in oral mucosal transudate (OMT) and fingerstick blood from patients with known anti-HCV serostatus and with or without active viremia (after treatment-induced clearance)., Study Design: A risk factor questionnaire was collected from 317 consecutive patients (anti-HCV positive/HCV-RNA positive n = 107; anti-HCV positive/HCV-RNA negative after antiviral treatment n = 107; anti-HCV negative with other liver diseases n = 109) before performing the OraQuick HCV rapid test in OMT (n = 317) and fingerstick blood (n = 251). We calculated the sensitivity and specificity of the test by using anti-HCV serostatus as the reference gold-standard., Results: Among all anti-HCV seropositive patients, the clinical sensitivity and specificity of the OraQuick HCV rapid test in OMT was 89.9% and 100%, respectively. In fingerstick blood, the sensitivity improved to 98.8%. The sensitivity was higher in OMT (97.2%) in anti-HCV seropositive patients who were viremic as compared to that in non-viremic individuals (82.2%). In contrast, there were no significant differences in sensitivity between viremic and non-viremic individuals when testing fingerstick blood. Finally, extension of the read time to 40 min enhanced the sensitivity, especially in OMT (up to 94.7%) and in the subgroup of non-viremic, anti-HCV-positive patients (up to 90.1%)., Conclusions: The OraQuick HCV rapid test in OMT has a high sensitivity and specificity for detecting active HCV infection that decreases substantially in anti-HCV positive/HCV-RNA negative patients with treatment-induced viral clearance. For these individuals, extension of read times and testing fingerstick blood showed improved sensitivity., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background and Aims: Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and real-world clinical practice, showed high rates of sustained virological response (SVR) in non-cirrhotic genotype (GT)-1 and GT-4 patients. These results were slightly lower in cirrhotic patients. We investigated real-life effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients., Methods: This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCV-GT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between January-2014 and December-2015. Demographic, clinical, virological and safety data were analysed., Results: Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELD≥10) or portal hypertension (platelet count≤100×10 9 /L, transient elastography≥21 Kpa) showed significantly lower SVR rates (84.4%-91.9%) than patients with less advanced liver disease (93.8%-95.9%, P<.01 in all cases). In the multivariate analysis, the use of RBV, female gender, baseline albumin≥35 g/L, MELD<10 and lack of exposure to a triple therapy regimen were independent predictors of SVR (P<.05). Serious adverse events (SAEs) and SAE-associated discontinuation events occurred in 5.9% and 2.6%., Conclusions: In this large cohort of cirrhotic patients managed in the real-world setting in Spain, SOF/SMV±RBV yielded to excellent SVR rates, especially in patients with compensated liver cirrhosis. In addition, this combination showed to be safe, with low rates of SAEs and early discontinuations., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)
