Considering Histologic Remission in Ulcerative Colitis as a Long-Term Target.

Monitoring disease activity in inflammatory bowel disease (IBD) is challenging since clinical manifestations do not represent reliable surrogates for an accurate reflection of the inflammatory burden. Endoscopic remission had been the most significant endpoint target in the last years; nevertheless, a remarkable proportion of patients continue to relapse despite a normal-appearing mucosa, highlighting that endoscopy may underestimate the true extent of the disease. A subtle hint of the importance that histology plays in the long-term course of the disease has been endorsed by the STRIDE-II consensus, which recommends considering histologic healing for ulcerative colitis (UC), even though it is not stated to be a compulsory formal target.

Bevacizumab Treatment for Metastatic Colorectal Cancer in Real-World Clinical Practice.

Colorectal cancer (CRC) is a leading cause of cancer-related mortality and morbidity worldwide. Bevacizumab was approved for the treatment of metastatic colorectal cancer (mCRC) based on favorable benefit-risk assessments from randomized controlled trials, but evidence on its use in the real-world setting is limited. The aim of the current study is to evaluate the outcomes and safety profile of bevacizumab in mCRC in a real-world setting in Romania.

Real World Efficacy and Safety of Sofosbuvir + Velpatasvir + Voxilaprevir in Romanian Patients with Genotype 1b HCV Infection Non-reponders to DAAs Therapy.

Background And Aims: The sofosbuvir (SOF) / velpatasvir (VEL) / voxilaprevir (VOX) combination has been evaluated in more than 800 patients enrolled in phase II and phase III studies, where it demonstrated excellent safety and efficacy, achieving overall sustained viral response (SVR) rates of more than 95%. We aimed to assess the efficacy and safety of SOF/VEL/VOX in a real-world study, including patients previously treated for genotype 1b hepatitis C virus (HCV) infection that did not obtain a sustained viral response with previous direct-acting antivirals (DAAs) therapy.

Methods: In Romania, through a nationwide government-funded program in 2019-2020, 213 patients with chronic hepatitis C non-responders to previous DAAs therapy, received treatment with SOF/VEL/ VOX 400/100/100 mg/day for 12 weeks.

Circulating Angiogenic Markers in Gastroenteropancreatic Neuroendocrine Neoplasms: A Systematic Review.

Background: Neuroendocrine neoplasms are a heterogeneous group of tumors that raise challenges in terms of diagnosis, treatment and monitoring. Despite continuous efforts, no biomarker has showed satisfying accuracy in predicting outcome or response to treatment.

Methods: We conducted a systematic review to determine relevant circulating biomarkers for angiogenesis in neuroendocrine tumors.

Molecular Signature of Persistent Histological Inflammation in Ulcerative Colitis with Mucosal Healing.

Background And Aims: Therapeutic targets in ulcerative colitis (UC) have evolved over time from clinical remission to biological and endoscopic remission. Histologic remission remains a debatable outcome due to lack of data regarding its impact on long-term evolution. The development of histologic activity scores has brought standardization.

Real-world efficacy and safety of ombitasvir, paritaprevir/r+dasabuvir+ribavirin in genotype 1b patients with hepatitis C virus cirrhosis.

Background: Direct antiviral agents (DAA) showed very good results in terms of efficacy and safety in clinical trials, but real-life data are still needed in order to confirm this profile.

Material And Methods: In Romania, through a nationwide government-funded programme in 2015-2016, approx.5800 patients with virus C cirrhosis received fully reimbursed DAA therapy with OBV/PTV/r+DSV+RBV for 12 weeks.

Entecavir plus tenofovir combination therapy for chronic hepatitis B in patients with previous nucleos(t)ide treatment failure.

Background And Aims: In patients with chronic hepatitis B (CHB) who have failed on other nucleos(t)ide analogs (NUCs), the combination of entecavir (ETV) plus tenofovir disoproxil fumarate (TDF), two potent agents with non-overlapping resistance profiles, may provide a single rescue regimen.

Methods: In this single-arm, open-label study, 92 CHB patients with a primary non-response, partial response, or virologic breakthrough on their current NUC were switched to ETV (1 mg) plus TDF (300 mg) and treated for 96 weeks.

Results: At baseline, 62 % of patients were HBeAg(+) and mean HBV DNA was 4.

Recent insights into the molecular pathogenesis of Crohn's disease: a review of emerging therapeutic targets.

Chronic inflammatory bowel diseases (IBDs) are a subject of great interest in gastroenterology, due to a pathological mechanism that is difficult to explain and an optimal therapeutic approach still undiscovered. Crohn's disease (CD) is one of the main entities in IBD, characterized by clinical polymorphism and great variability in the treatment response. Modern theories on the pathogenesis of CD have proven that gut microbiome and environmental factors lead to an abnormal immune response in a genetically predisposed patient.

Prevalence and impact on survival of hepatopulmonary syndrome and cirrhotic cardiomyopathy in a cohort of cirrhotic patients.

Background & Aims: Extrahepatic complications of cirrhosis increase the risk for decompensation of the liver disease and death. Previous studies show common pathogenetic mechanisms involved in the development of hepatopulmonary syndrome and cirrhotic cardiomyopathy. We aimed to assess the link between these entities and their effect on disease-related patient morbidity and mortality.

Effectiveness of entecavir treatment and predictive factors for virologic response.

Introduction: Entecavir (ETV) is a potent inhibitor of hepatitis B virus (HBV) replication. In patients adherent to treatment, virologic remission rates of > 95 % can be maintained with entecavir at 3-5 years.

Aim And Methods: A cohort study was performed, including all subjects who received ETV for chronic hepatitis B, in the South- Eastern Romania.

Endoscopic knot tying: In vitro assessment in a porcine stomach model.

Aim: To determine if surgical knotting performed via endoscopy is an effective closure method for natural orifice translumenal endoscopic surgery.

Methods: The proposed method was tested on an in vitro pig stomach model using standard endoscopy suite materials. A single use laparoscopy trocar (Versaport Plus manufactured by Tyco Healthcare) was fixed onto a plastic rectangular box in a horizontal position.

Nuclear Division Index may Predict Neoplastic Colorectal Lesions.

Background: Colorectal cancer (CRC) develops by accumulation of multiple genetic damages leading to genetic instability that can be evaluated by cytogenetic methods. In the current study we used Cytokinesis-Blocked Micronucleus Assay (CBMN) technique to assess the behavior of Nuclear Division Index(NDI) in peripheral lymphocytes of patients with CRC and polyps versus patients with normal colonoscopy.

Methods: Blood samples were collected from patients after informed consent.
