Efficacy and safety of biosimilars in gastroenterology: a focus on inflammatory bowel disease management.

Introduction: The introduction of biosimilars changed the management of biologicals in inflammatory bowel disease (IBD) since the approval of CT-P13, the first biosimilar to infliximab, by the European Medicines Agency (EMA) in September 2013 and by the U.S. Food and Drug Administration (FDA) in April 2016.

The Role of Histology Alongside Clinical and Endoscopic Evaluation in the Management of IBD-A Narrative Review.

Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory conditions requiring continuous monitoring. Today, endoscopy is the gold standard for assessing disease activity, with histological evaluation providing additional insights. Studies suggest that persistent histological inflammation, despite endoscopic remission, may be associated with a higher risk of relapse in UC, suggesting its role in treatment decisions.

[Anemia classification, prevalence and predictive factors in inflammatory bowel disease].

Introduction: Anemia is a common complication of inflammatory bowel disease and serves as an indicator of severe disease. Objective: This study aims to evaluate the prevalence, etiology, predictive factors, and treatment of anemia in patients with inflammatory bowel disease from two tertiary centers. Method: In this retrospective, cross-sectional study, we assessed the frequency of anemia among patients presenting within a specified calendar year (June 1, 2022, to May 31, 2023), focusing on the lowest hemoglobin levels recorded during this period.

Inflammatory bowel diseases in the elderly population: epidemiology, long-term disease course, surgery rates, and biological use-data from the Veszprem county cohort between 1977 and 2020.

Background And Aims: Limited data are available on long-term disease outcomes in elderly-onset (EO) inflammatory bowel diseases (IBD) from well-defined population-based cohorts. Our aim was to analyze incidence, disease course, surgery rates, and therapeutic strategies of EO IBD in a prospective population-based cohort.

Methods: Elderly-onset inflammatory bowel diseases were defined if diagnosis was established at ≥60 years of age.

Efficacy, drug sustainability, and safety of ustekinumab treatment in Crohn's disease patients over three years.

Long-term data on ustekinumab in real-life Crohn's disease patients are still missing, though randomized controlled trials demonstrated it as a favorable therapeutic option. We aimed to evaluate ustekinumab's clinical efficacy, drug sustainability, and safety in a prospective, nationwide, multicenter Crohn's disease patient cohort with a three-year follow-up. Crohn's disease patients on ustekinumab treatment were consecutively enrolled from 9 Hungarian Inflammatory Bowel Disease centers between January 2019 and May 2020.

Burden of Mental Health among Patients with Inflammatory Bowel Disease-A Cross-Sectional Study from a Tertiary IBD Center in Hungary.

Inflammatory bowel diseases (IBDs) are chronic conditions that negatively affect the patient's quality of life. With the spread of the biopsychosocial model, the role of mental health in the activity and course of inflammatory bowel disease is becoming more and more recognized. Our study aimed to assess the prevalence of anxiety and depression in IBD patients in our tertiary referral center and determine the predictive factors of these mental conditions.

Burden of perianal disease in Crohn's disease: Accelerating medical therapy and high rates of perianal surgery over the last four decades - Results from a population-based study over four decades.

Background: Few population-based studies have investigated the prevalence and disease course of perianal manifestation in Crohn's disease.

Aims: To analyse the prevalence and outcomes of perianal Crohn's disease including medical therapies and need for perianal surgery, over different therapeutic eras based on the time of diagnosis; cohort A (1977-1995), cohort B (1996-2008), and cohort C (2009-2018) METHODS: Patient inclusion lasted between 1977 and 2018. We followed patients prospectively, and regularly reviewed both in-hospital and outpatient records.

[Malignant solid tumor associated with hypereosinophilic syndrome].

Hypereosinophilic syndrome is characterized by chronic eosinophil overproduction, resulting in multiple organ damages due to eosinophil infiltration and mediator release. According to the etiology, we distinguish between myeloproliferative disorders, parasitic infections, solid tumors, T-cell lymphomas and idiopathic forms. In our case report, the 49-year-old man was hospitalized with weight loss, leg edema and tachycardia.

New distribution records of subterranean crustaceans from cenotes in Yucatan (Mexico).

New records of 14 stygobiont crustacean species pertaining to six Malacostraca orders from 32 cenotes are presented, with their associated caves of the state of Yucatan, Mexico, together with an individual account for each species. Species composition of most of the investigated cenotes is examined for the first time. A thermosbaenacean and two amphipod species were not formally recorded to the cenote ecosystems of the state of Yucatan prior to our research.

Continental data on cave-dwelling spider communities across Europe (Arachnida: Araneae).

Background: Spiders (Arachnida: Araneae) are widespread in subterranean ecosystems worldwide and represent an important component of subterranean trophic webs. Yet, global-scale diversity patterns of subterranean spiders are still mostly unknown. In the frame of the CAWEB project, a European joint network of cave arachnologists, we collected data on cave-dwelling spider communities across Europe in order to explore their continental diversity patterns.

, a new subterranean amphipod species from Yucatán state, México (Amphipoda, Hadziidae).

A detailed description of a new stygobiont species of the amphipod family Hadziidae, Angyal, is given, based on material collected in four cenotes of Yucatán federal state, México. Morphology was studied under light microscopy and with scanning electron microscopy. Morphological description is complemented with mitochondrial cytochrome c oxidase subunit I (COI) sequences as barcodes, with affinities to the related taxa and with notes on the species' ecology.

Description of the male and the larva of Ixodes ariadnae Hornok, 2014.

Ixodes ariadnae is a tick species of bats so far reported only in Central Europe, with its description based on the female and nymph. This study describes the male and larva in order to complete the description of the species. Male ticks collected from cave walls in Hungary showed a different morphology from those of I.

Niphargus (Crustacea: Amphipoda) species in Hungary: literature review, current taxonomy and the updated distribution of valid taxa.

Research of the Hungarian Niphargus species is a rather neglected field. This is due to the growing distance between the  level of knowledge about Hungarian species and the elaboration determined by the international publications, which had caused a hardly negotiable inconvenience in the judgment of the state of the Hungarian species. The clarification of species in questionable positions could be the starting point of further inland research.

Redescription of two subterranean amphipods Niphargusmolnari Méhely, 1927 and Niphargusgebhardti Schellenberg, 1934 (Amphipoda, Niphargidae) and their phylogenetic position.

A detailed redescription of two endemic, cave-dwelling niphargid species of the Hungarian Mecsek Mts., Niphargusmolnari Méhely, 1927 and Niphargusgebhardti Schellenberg, 1934 is given based on newly collected material. Morphology was studied under light microscopy and with scanning electon microscopy.

Bat ticks revisited: Ixodes ariadnae sp. nov. and allopatric genotypes of I. vespertilionis in caves of Hungary.

Background: In Europe two ixodid bat tick species, Ixodes vespertilionis and I. simplex were hitherto known to occur.

Methods: Bat ticks were collected from cave walls and bats in Hungary.
