Association of polymorphic variants in serotonin re-uptake transporter gene with Crohn's disease: a retrospective case-control study.

Aim: To analyze the distribution of SLC6A4 gene polymorphisms in Crohn's disease (CD) patients and their association with the disease.

Methods: We evaluated the presence/absence of promoter (5-HTTLPR, rs25531) and intron 2 (STin2 VNTR) polymorphic variants of SLC6A4 gene in a retrospective case-control study including 192 CD patients and 157 healthy controls (HC). Genotyping was performed by polymerase chain reaction.

3rd European Evidence-based Consensus on the Diagnosis and Management of Crohn's Disease 2016: Part 2: Surgical Management and Special Situations.

This paper is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the diagnosis and management of Crohn's disease [CD] and concerns the surgical management of CD as well as special situations including management of perianal CD and extraintestinal manifestations. Diagnostic approaches and medical management of CD of this ECCO Consensus are covered in the first paper [Gomollon et al JCC 2016].

ATP7B Gene Mutations in Croatian Patients with Wilson Disease.

Aims: Wilson disease (WD) is an autosomal recessive disorder of copper metabolism, characterized by its accumulation in tissues which results in hepatic, neurological, and/or psychiatric symptoms. The aim of this study was to investigate the genetics of WD in Croatian patients.

Methods: Correlation of the clinical presentation subtype and the age at onset of the diagnosis of WD with the ATP7B genotype was investigated in a group of Croatian WD patients.

[Croatian guidelines for gastric cancer prevention by eradication of Helicobacter pylori infection].

Gastric cancer is the fourth most common type of cancer and the second leading cause of cancer-related death in the world. Although gastric cancer has a multifactorial etiology, infection with Helicobacter pylori is highly associated with gastric carcinogenesis. Carcinogenesis is also influenced by some environmental factors and host genetic diversity, which engenders differential host inflammatory responses that can influence clinical outcome.

[Assessment of liver disease severity in patients with chronic viral hepatitis].

The best indicator of the severity of liver damage and prognosis in chronic viral hepatitis is extension of liver fibrosis. Extension of liver fibrosis can be assessed by liver biopsy and non-invasive physical or biological methods. Biopsy is used to define ethiology, severity (stage of fibrosis) and prognosis of liver disease.

[Viralhepatitis. Croatian Consensus Statement 2013].

Croatian Consensus Conferences on Viral Hepatitis took place in 2005 and 2009. Considering the numerous novel concepts on the epidemiology, diagnosis and management of viral hepatitis (chronic hepatitis C genotype 1 in particular) that have emerged in the past four years, a new Croatian Consensus Conference on Viral Hepatitis was held in Zagreb on February 28, 2013. The abridged text of the Croatian Consensus Conference on Viral Hepatitis 2013 presents the new concepts on the epidemiology of viral hepatitis, serologic and molecular diagnosis of viral hepatitis, determination of the IL-28 gene promoter polymorphism, fibrosis grading, algorithm for patient diagnostic follow up, treatment of chronic hepatitis C (genotypes 1-6) and hepatitis B, treatment of special populations (children, dialysis patients, transplanted patients, individuals with HIV/HCV co-infection), and therapy side effects.

Health-related quality of life improves during one year of medical and surgical treatment in a European population-based inception cohort of patients with inflammatory bowel disease--an ECCO-EpiCom study.

Background & Aims: Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe.

Methods: The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.

[The role of anti-TNF therapy in ulcerative colitis].

Anti-TNF-alfa molecules are currently being used to treat ulcerative colitis regarding to the fact that TNF-alpha has an important role in the pathogenesis of IBD. Although these drugs improved the therapy of patients, immunogenicity limits their potential for clinical use. Infliximab and adalimumab are effective for induction and maintenance of remission in outpatients with moderate to severe steroid-refractory ulcerative colitis.

[Croatian consensus on the treatment of inflammatory bowel diseases with biologic therapy].

Introduction of biologic therapy in clinical practice represented significant progress in the treatment of inflammatory bowel diseases (IBD) because of its proven efficacy and due to the fact that biologics are the first drugs used in the treatment of IBD that can change the natural course of this diseases. At the same time, biologics are very expensive drugs with complex mechanism of action and important side effects and their use requires evidence-based clinical guidelines. These were the reasons that Referral Center of the Croatian Ministry of Health for IBD and the IBD Section of the Croatian Society of Gastroenterology organised Croatian consensus conference that defined guidelines for the treatment of IBD with anti-TNF drugs.

Prior statin therapy is associated with milder course and better outcome in acute pancreatitis--a cohort study.

Background: Statin treatment was shown to be associated with improved outcomes in several inflammatory conditions. We wanted to evaluate the effects of statin therapy on the course and outcome of acute pancreatitis (AP).

Methods: A prospective cohort study included patients with acute pancreatitis divided into two groups according to statin use prior to hospitalization.

[Inflammatory bowel disease].

Inflammatory bowel disease (IBD) is heterogenous group of inflammatory disorders characterized by chronic immune activation and inflammation of the gastrointestinal tract, associated with numerous extraintestinal manifestations. Two most important forms are Crohn's disease and ulcerative colitis with several phenotypes. Etiopathogenesis of IBD is still unknown.

[Intraductal papillary mucinous neoplasm of the pancreas: case report and review of the literature].

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a relatively rare clinical entity with a main characteristic being mucus production. Extension of IPMN along pancretic ducts and mucus production lead to ductal obstruction and dilatation, resulting in recurrent episodes of acute pancreatitis. Molecular background of IPMN-a comprises several aberrations, with the K-ras gene mutation being the likely trigger that initiates further genetic changes.

[Endoscopic mucosal resection of sessile polypoid colorectal lesions: a two-year retrospective study, technique description, indications and complications].

Introduction: Endoscopic mucosal resection (EMR) is a therapeutic method for removal of sesile premalignant lesions and intramucosal carcinoma of the gastrointestinal tract. No reports on EMR data in Croatia have been published yet.

Materials And Methods: All patients included in the study were managed at the University Hospital Centre Zagreb between December 2006 and December 2008.

Role of acid suppression in the development and progression of dysplasia in patients with Barrett's esophagus.

Barrett's esophagus (BE) usually develops in patients with gastroesophageal reflux disease and therefore it has been suggested that esophageal acid exposure plays an import role in the initiation of BE and its progression towards esophageal adenocarcinoma (EAC). The mechanisms whereby acid exposure causes BE are not completely revealed and the potential role of esophageal acid exposure in carcinogenesis is unclear as well. Since acid exposure is thought to play an important role in the progression of BE, therapies aimed at preventing the development of EAC have primarily focused on pharmacological and surgical acid suppression.

A pilot study of transrectal endoscopic ultrasound elastography in inflammatory bowel disease.

Background: Using standard diagnostic algorithms it is not always possible to establish the correct phenotype of inflammatory bowel disease which is essential for therapeutical decisions. Endoscopic ultrasound elastography is a new endoscopic procedure which can differentiate the stiffness of normal and pathological tissue by ultrasound. Therefore, we aimed to investigate the role of transrectal ultrasound elastography in distiction between Crohn's disease and ulcerative colitis.

Pegylated interferon for treatment of chronic hepatitis C in hemodialysis patients in Croatia.

Background And Aims: Hepatitis C virus (HCV) infection is a frequent complication among long-term dialysis patients. The aim of the present study was to evaluate the efficacy and side effects of pegylated interferon-α(2a) (PEG-IFN-α(2a)) treatment in hemodialysis patients.

Methods: We retrospectively reviewed charts of 16 HCV-RNA-positive hemodialysis patients.

Appropriate therapy for fistulizing and fibrostenotic Crohn's disease: Results of a multidisciplinary expert panel - EPACT II.

Introduction: Many therapeutic decisions in the management of fistulizing and fibrostenotic Crohn's disease (CD) have to be taken without the benefit of strong scientific evidence. For this reason, explicit appropriateness criteria for CD fistula and stenosis treatment were developed by a multidisciplinary European expert panel in 2004 with the aim of making them easily available on the Internet and thus allowing individual case scenario evaluation; these criteria were updated in 2007.

Methods: Twelve international experts convened in Geneva, Switzerland in December 2007.

[Croatian guidelines for use of enteral nutrition in Crohn's disease].

Nutrition has an important role in the management of inflammatory bowel disease (IBD), especially in patients with Crohn's disease (CD). This role includes the prevention and correction of malnutrition, the prevention of osteoporosis and the promotion of optimal growth and development in children. In active Crohn's disease, nutritional therapy (in the form of enteral feeding) is an effective primary therapy for pediatric patients.

[Retreatment options for patients with chronic hepatitis C].

Despite impressive therapy improvements, there still are a huge proportion of patients that will fail to achieve undetectable HCV. On the other hand, not all patients that demonstrate some response to treatment attain a sustained viral response. Patients with HCV non-response can be classified into several groups: 1) non-response (where the patient does not achieve undetectable HCV RNA at any time); 2) partial response (when the patient experiences some drop in HCV viremia but never below the detectable limit); 3) viral breakthrough (those associated with an initial virologic response, which is subsequently lost during treatment); and 4) relapse (those with an initial virologic response, which is lost upon treatment discontinuation).

[Assessment of hepatic injury in patients with chronic viral hepatitis].

The management and prognosis of chronic viral hepatitis greatly depend on the extent and progression of liver fibrosis. Although liver biopsy is still considered as the gold standard to evaluate hepatic fibrosis, it is an invasive procedure with rare but potentially severe complications. It is also prone to sampling errors.
