Introduction: COVID–19 significantly affects endoscopic labs’ workflow. Endoscopic examinations are considered high-risk for virus transmission. Objectives: To determine impact of COVID–19 pandemic on Hungarian endoscopic labs’ workflow and on infection risk of endoscopic staff. Method: A nation-wide, cross-sectional online questionnaire was sent to heads of endoscopic labs in Hungary. The average number (with 95% confidence intervals) of upper and lower gastrointestinal endoscopies performed in 2020 was compared to that in 2019. The number of SARS-CoV-2-infected endoscopic staff members and the source of infection was also investigated. Results: Completion rate was 30% (33/111). Neither the number of upper (1.593 [743–1.514] vs. 1.129 [1.020–2.166], p = 0.053), nor that of lower gastrointestinal endoscopies (1.181 [823–1.538] vs. 871 [591–1.150], p = 0.072) decreased in 2020, but both upper and lower gastrointestinal endoscopies’ number decreased by 80% during peak phases. Separate examination room was available in 12% of institutes. Appropriate quality personal protective equipment (PPE) was available during the first and second peak phase in 70% and 82%, respectively. Infection risk stratification by questionnaire and PCR testing was routinely performed in 85% and 42%, respectively. Employee number decreased by 33% and 26% for physicians, and by 19% and 21% for assistants during peak phases, mainly due to age restrictions and COVID care assignments. 32% of assistants and 41% of physicians were infected (associated with inappropriate PPE use in 16% and 18%, respectively). Conclusion: Peak phases’ restrictions increase endoscopic workload afterwards. Despite PPE availability, 15% of employees’ COVID infection resulted from inappropriate PPE use in pre-vaccination era.Bevezetés: A COVID–19-pandémia jelentősen befolyásolta az endoszkópos laboratóriumok működését. Az endoszkópos vizsgálatok nagy vírusátviteli rizikójúnak számítanak. Célkitűzés: A koronavírus-járványnak a magyarországi endoszkópos laborok működésére kifejtett hatásának és az endoszkópos személyzet SARS-CoV-2-fertőzésben való érintettségének felmérése a 2020-as évben. Módszerek: Országos szintű, keresztmetszeti, kérdőíves tanulmányunk során magyarországi endoszkópos laboratóriumok vezetőit kerestük meg online formában. Vizsgáltuk a 2020-ban elvégzett felső és alsó tápcsatornai endoszkópiák számát a 2019-es referenciaévhez viszonyítva (átlag [95%-os konfidenciaintervallum]), továbbá a SARS-CoV-2-fertőzéssel érintett dolgozók számát és fertőződésük potenciális forrását. Eredmények: A megkeresett intézmények 30%-ából érkeztek válaszok (33/111). A referenciaévhez képest sem a felső (1593 [743–1514] vs. 1129 [1020–2166], p = 0,053), sem az alsó tápcsatornai endoszkópos vizsgálatok száma (1181 [823–1538] vs. 871 [591–1150], p = 0,072) nem csökkent, bár a vírushullámoknak megfelelően mindkét vizsgálattípus esetén 80%-ot meghaladó vizsgálatszám-csökkenést tapasztaltunk. Dedikáltan fertőző betegek vizsgálatára kialakított helyiség az intézetek 12%-ában állt rendelkezésre. A védőfelszerelések az első és a második hullám alatt 70%-ban, illetve 82%-ban voltak mennyiségileg és minőségileg megfelelőek. A vizsgálat előtt fertőzöttségirizikó-stratifikáció az intézetek 85%-ában, míg PCR-vizsgálat csupán 42%-ukban történt minden esetben. Az első és második járványhullám alatt a dolgozói létszám az orvosoknál 33%-kal, illetve 26%-kal, az asszisztenseknél 19%-kal, illetve 21%-kal csökkent, elsősorban életkori korlátozás, COVID-ellátásba való áthelyezés miatt. Az asszisztensek 32%-a, az orvosok 41%-a esett át COVID-fertőzésen, 16%-ban, illetve 18%-ban nem megfelelő védőfelszerelés-használattal összefüggésben. Következtetés: A járványhullámok alatti restrikciók feloldását követően a vizsgálati terhelés emelkedik. A SARS-CoV-2-vakcinák elérhetősége előtt az endoszkópos laborok dolgozóit érintő COVID-fertőzések 15%-a nem megfelelő védőfelszerelés-használattal volt összefüggésbe hozható.

The relationship between clinical outcomes and serum anti-TNF levels is controversial. TheConsecutive IBD patients who received maintenance anti-TNF-α therapy were enrolled. The number of TNF-α positive cells in the mucosa was detected using immunofluorescent labeling on biopsy samples. Serum, mucosal and fecal anti-TNF-α, serum anti-drug antibody, and fecal calprotectin levels were determined using ELISA. Each patient underwent body composition analysis as well.Data of 50 patients were analyzed. The number TNF-α positive cells was significantly higher in the inflamed part of the colon than in the un-inflamed part of the colon. Tissue and fecal drug levels did not show any association with serum drug levels; moreover, serum anti-TNF concentration did not correlate with endoscopic activity. Mucosal anti-TNF levels were higher only in IFX-treated patients in remission and IFX-treated patients with detectable fecal anti-TNF had lower tissue drug levels. Presence of the drug in the feces was significantly different according to disease activity.Fecal drug concentration is suggested to be a better predictor of endoscopic activity and loss of response, and fecal drug monitoring may improve the estimation accuracy of tissue drug levels.

Introduction: Patients with inflammatory bowel disease (IBD) have an increased risk to develop malignant neoplasms. Neither the exact mechanism, nor the frequency of different malignancies is completely clear. Our aim was to assess the IBD associated malignancies, to collect clinical and mortality data and to analyse possible risk factors. Methods: Data on malignancies developed between January 2015 and May 2019 in Hungarian IBD patients was recorded. Every member of the Hungarian Society of Gastroenterology was prospectively interviewed. The following data were collected: demographic data, disease characteristics, previous therapy, patient adherence, type and localisation of malignancies. Results: 140 IBD patients with newly diagnosed malignancies were reported. 61.4%, 35.7%, and 2.9% of the patients had ulcerative colitis (UC), Crohn’s disease (CD) and indeterminate colitis, respectively. The mean latency was 15.2±10.5 years. Colorectal cancer (CRC) was the most common cancer (49.6%, 70). 72.9% (51/70) of them was associated with UC, more than 80% had extensive (50.9%, 26) and left-sided (31.2%, 16) colitis. The most frequent CRC localisation was the rectosigmoid colon in UC (54.9%), and the rectum in CD (38.9%). The most common non-CRC malignancies were non-melanotic skin-cancer, haematological and pulmonary cancer. Disease duration at the time of the diagnosis of malignancy was lower (17.9±10.7 versus 12.6±9.7 years); mean age at the time of the death was higher (49.3±9.4 versus 64.3±16.4 years); and survival was longer after the diagnosis of extraintestinal malignancy than CRC (0.73±1.01 versus 1.2±0.8). Summary: CRC presented typically in the distal part of the colon by male UC patients with pancolitis or left-sided colitis with a long-standing disease course of IBD. The most common non-CRC malignancies were non-melanotic skin cancer, haematological cancer and lung cancer. Non-CRC malignancies developed typically in female patients, older than CRC patients with shorter disease-course of IBD and longer survival times.

In this cross-sectional, real-life study we have investigated the potential association between 6-thioguanine nucleotide (6-TGN) and anti-TNF [infliximab (IFX), adalimumab (ADA)], anti-drug antibody levels and body composition parameters. Based on our results thiopurine and anti-TNF combination therapy resulted in decreased antibody formation in IFX-treated patients. AZA-ADA-treated patients showed increased anti-TNF drug concentrations, regardless of antibody formation. Drug metabolites did not correlate with body composition parameters.

Objective The efficacy of argon plasma coagulation (APC) on gastric antral vascular ectasia (GAVE) may be impaired over time and depends greatly on the application settings. Endoscopic band ligation (EBL) may be an alternative, but study on its efficacy is limited. This study aimed to evaluate and compare the clinical efficacy of APC and EBL in treating GAVE. Methods Changes in the need for blood transfusion, number of treatment sessions and hospitalizations were retrospectively assessed in 63 transfusion-dependent patients with GAVE (mean age: 67.1 y, 54.0% female) treated with either APC or EBL (45 and 18 patients, respectively) in four tertiary endoscopic centers. Results Both methods substantially increased hemoglobin levels and decreased patients' need for a transfusion (22.0 ± 4.0 g/L and -5.62 ± 2.30 units of packed red blood cells [RBC] with APC, and 27.4 ± 6.1 g/L and -4.79 ± 2.46 units of packed RBC with EBL), without a significant statistical difference between the methods. However, fewer EBL sessions were required both for the cessation of need for a transfusion compared with those for the resolution of GAVE lesions (0.90 ± 0.10 vs 1.69 ± 0.31, P = 0.028). Conclusions Both APC and EBL are effective in GAVE treatment. EBL may be superior in terms of number of treatment sessions, but not in its influence on hemoglobin level and need for transfusion. Further prospective studies with large, homogeneous sample size and standardized APC settings are needed.

Ezek a hatóanyagok hatékonyak, ám hosszú távú hatásosságukkal kapcsolatban sok az ellentmondás. Célkitűzés: Vizsgálatunk célja megvizsgálni az anti-TNFα-terápia (infliximab [IFX], adalimumab [ADA]) hosszú távú hatékonyságát gyulladásos bélbetegek körében. Módszerek: Retrospektív, adatgyűjtéses vizsgálatunkba a Szegedi Tudományegyetem I. Sz. Belgyógyászati Klinikáján gondozott, 18–65 év közötti gyulladásos bélbetegeket vontunk be. Az adatgyűjtést a Klinika informatikai rendszeréből végeztük a betegek ambuláns megjelenéseinek kezelőlapjaiból, illetve a zárójelentésekből. Eredmények: 102 beteg adatait elemeztük (Crohn-beteg: 67 fő, colitis ulcerosás: 35 fő). A Crohn-betegség diagnózisát követően átlagosan 7,84 év, a colitis ulcerosa diagnózisát követően átlagosan 9,86 év telt el az első anti-TNFα-terápia elkezdéséig. Az első kezelési ciklus átlagosan 2,64 évig tartott, a ciklus végén az IFX-t kapó betegek 50%-ánál, az ADA-t kapó betegek 46%-ánál volt remisszióban a betegség. A második kezelési ciklus átlagosan 4,67 évig tartott, a ciklus végén az IFX-t kapó betegek 36%-a, az ADA-t kapó betegek 40%-a volt remisszióban. Az első, illetve a második kezelési ciklus alatt az allergiás reakciók gyakorisága IFX esetében 13% és 18%, ADA esetében 4% és 3% volt. A primer hatástalanság és a másodlagos hatásvesztés az első ciklusban IFX esetében 4% és 10,5%, ADA esetében 11,5% és 19% volt. A második kezelési ciklusban IFX esetében 9%-ban és 18%-ban, ADA esetében 23%-ban és 10%-ban jelentették a ciklus végét. Következtetés: Az anti-TNFα-terápiák eredményeink alapján hosszú távon is hatékonynak és biztonságosnak bizonyultak. Másodlagos hatásvesztés kisebb arányban fordult elő a vizsgált populációban az irodalmi adatokhoz képest. Orv Hetil. 2020; 161(47): 1989–1994. Summary. Introduction: Anti-tumor necrosis factor-alpha (anti-TNFα) treatment is reserved for steroid-dependent or steroid/immunomodulator-refractory inflammatory bowel diseases patients. These agents are effective, however, their long-term safety is still questionable. Objective: We aimed to assess the long-term efficacy and safety of two anti-TNFα therapies. Methods: In our retrospective study, we reviewed medical records via the administration system of the First Department of Medicine, University of Szeged. Female and male patients, aged between 18–65 years who received anti-TNFα therapy between 2010–2019 were enrolled. Results: 102 patients with inflammatory bowel disease were enrolled (Crohn’s disease: 67, ulcerative colitis: 35). The first anti-TNFα therapy was introduced after an average 7.84 and 9.86 years from diagnosis of Crohn’s disease and ulcerative colitis. The first treatment period lasted for 2.64 years; 50% of patients receiving IFX and 46% of patients receiving ADA were in remission at the end of the period. The second treatment period lasted for 4.67 years, 36% of IFX-treated patients and 40% of ADA-treated patients were in remission at the end of the period. 13% and 18% of patients treated by IFX and 4% and 3% of patients treated by ADA experienced infusion reaction during the first and the second treatment period. Primary non-response and loss of response rates were 4% and 10.5% (IFX) and 11.5% and 19% (ADA) during the first treatment period. These rates were 9% and 18% (IFX) and 23% and 10% (ADA) during the second treatment period. Conclusion: Our study confirmed the long-term efficacy and safety of the anti-TNFα therapies. Loss of response rate is lower in our population compared to the literature. Orv Hetil. 2020; 161(47): 1989–1994.

Background/aim: In Hungary, a nationwide colorectal screening program is about to be introduced in order to improve the high mortality rate of colorectal cancer CRC . The aim was to summarize experiences from and assess short-term efficacy of the populationbased pilot colorectal screening program in 2015 in Csongrád county, Hungary. Materials and methods: Asymptomatic individuals between the ages of 50 and 70 with average risk of colorectal cancer participated in the program that was based on the two-step screening method: immune fecal blood test and colonoscopy. The short-term efficacy was assessed as the change in total CRC incidence and initial tumor stage in the screening year 2015 . Results: 22,130 individuals were invited to participate, and the participation rate was 46.4%. Immune fecal blood test proved to be nonnegative in 1,343 cases 13% , screening colonoscopy was performed in 766 of them 7.5% . Total colonoscopy was performed in 711 individuals. Based on the reports, adenoma was detected in 358 50.3% and malignancy in 42 5.9% individuals. In the background population, the incidence of colon cancer was higher 183 vs. 228; P = 0.026 and was diagnosed at earlier stage P = 0.002 , while lymph node involvement was lower in 2015 48.3% vs. 37.1%; P = 0.049 . Conclusion: The Csongrád county population-based colorectal cancer screening was evidently successful on the short-term considering participation rate, and the changes in CRC incidence and stage, thus its national extension is necessary.

Background: Treatment with antitumor necrosis factor alpha (anti-TNF-α) is safe and effective as first-line therapy; however, its efficacy is limited due to primary nonresponse (PNR) and secondary loss of response (LOR), resulting in treatment discontinuation in approximately 40%–50% of cases. Vedolizumab (VDZ) and ustekinumab (UST) therapies could be good alternatives in patient with anti-TNF failure; however, no head-to-head randomized comparison of these drugs as second- or third-line treatments has been made. Objectives: This study aimed to assess the treatment persistence and comparative effectiveness of UST and VDZ in patients with refractory Crohn’s disease (CD). Design: In this nationwide retrospective study, patients with CD on UST or VDZ maintenance therapy were enrolled. Clinical data at baseline, after induction, and at week 52 were obtained. Methods: Clinical and biochemical activities as well as corticosteroid-free remission (SFR) rates were assessed, while concomitant medications, comorbidities, hospitalizations, and surgeries were recorded during the follow-up to detect any predictors. Results: A total of 161 UST- and 65 VDZ-treated patients completed the follow-up. No significant difference in clinical or biochemical remission rates was observed after induction between the two treatment groups; however, clinical remission rate at week 52 was higher in UST group. UST showed superior drug persistence than VDZ (86.5%, 57.9%, p Conclusions: VDZ and UST were safe and effective for treating patients with CD in whom anti-TNF therapy failed. UST showed superior drug persistence than VDZ, but dose escalation was more frequent. Biologicals used in lower treatment lines resulted in better drug persistence.

BACKGROUND AND AIMS: There is a need to evaluate the benefit-risk ratio of current therapies in inflammatory bowel disease (IBD) patients to provide the best quality of care. The primary objective of I-CARE (IBD Cancer and serious infections in Europe) was to assess prospectively safety concerns in IBD, with specific focus on the risk of cancer/lymphoma and serious infections in patients treated with anti-tumor necrosis factor and other biologic monotherapy as well as in combination with immunomodulators.METHODS: I-CARE was designed as a European prospective longitudinal observational multicenter cohort study to include patients with a diagnosis of Crohn's disease, ulcerative colitis, or IBD unclassified established at least 3 months prior to enrollment.RESULTS: A total of 10,206 patients were enrolled between March 2016 and April 2019, including 6169 (60.4%) patients with Crohn's disease, 3853 (37.8%) with ulcerative colitis, and 184 (1.8%) with a diagnosis of IBD unclassified. Thirty-two percent of patients were receiving azathioprine/thiopurines, 4.6% 6-mercaptopurine, and 3.2% methotrexate at study entry. At inclusion, 47.3% of patients were treated with an anti-tumor necrosis factor agent, 8.8% with vedolizumab, and 3.4% with ustekinumab. Roughly one-quarter of patients (26.8%) underwent prior IBD-related surgery. Sixty-six percent of patients had been previously treated with systemic steroids. Three percent of patients had a medical history of cancer prior to inclusion and 1.1% had a history of colonic, esophageal, or uterine cervix high-grade dysplasia.CONCLUSIONS: I-CARE is an ongoing investigator-initiated observational European prospective cohort study that will provide unique information on the long-term benefits and risks of biological therapies in IBD patients. (EudraCT, Number: 2014-004728-23; ClinicalTrials.gov, Number: NCT02377258).

Although the exact aetiology of inflammatory bowel disease (IBD) is unknown, one hypothesis suggests that the inflammation may be the consequence of an altered or pathogenic microbiota in a genetically susceptible host. The aim of this study was to assess the frequency of enteral infections in patients with relapse of IBD, and to evaluate the clinical utility of faecal calprotectin (FC) and faecal matrixmetalloproteinase- 9 (MMP-9) in the differential diagnosis of relapses with different origins, and to determine the recurrence rate of Clostridioides difficile (C. difficile), the hospitalisation and colectomy rate among C. difficile positive IBD patients at the end of 4 years follow-up period. Methods: In this prospective, “real life” study clinical data, serum and stool samples were assessed. Results: Overall, 135 outpatients with IBD were enrolled [91 IBD patients who relapsed and 44 subjects in clinical remission (control group)]. C. difficile A/B toxins were detected in 42.2% of all cases. Candida was presented in 9.9% among the enrolled subjects. We found significant difference between FC and MMP-9 values in patients in relapse and remission, but not in C. difficile positive and negative cases. Our results revealed an association between previous antibiotic use and the rate of toxigenic C. difficile. Toxigenic C. difficile positivity recurrence rate was 4.4%. Hospitalisation during follow-up due to IBD was 45.4% and 35% in C. difficile positive and negative group, respectively. Value of FC and MMP-9 did not predict the need of hospitalisation. Conclusions: The occurrences of toxigenic C. difficile and Candida positivity were excessively high in our patients in an acute relapse, which suggests the importance of intestinal microbiota in IBD. FC and MMP-9 has no diagnostic value to differentiate between infection-induced and natural relapse. In our study was confirmed that hospitalisation rate was higher in C. difficile positive cases, but we did not find any relationship on long-term period.

Background: There are contradictory results about the effect of magnesium citrate plus sodium picosulfate bowel cleansing agents on the fluid and electrolyte balance. Therefore, this study aimed to determine the efficacy, tolerability and safety of this medication in colonoscopy preparation. Methods: 233 patients were enrolled in this phase IV prospective observational study. The effectiveness of bowel cleansing was assessed using the Boston Bowel Preparation Scale (BBPS). Adequate cleansing was defined as BBPS ≥ 6 and excellent cleansing as BBPS > 7. Tolerability was examined using a standardized questionnaire. In the safety analysis, the change of serum electrolytes levels and renal function during bowel cleansing was assessed. Results: Adequate and excellent bowel cleansing were achieved 94.85% and 72.96% of cases, respectively. None or very mild symptoms were reported in 47.21% of cases. Statistically significant changes occurred in serum potassium (4.38±0.43 vs. 4.25±0.43 mmol/L, p

Background Health care professionals in endoscopic labs have an elevated risk for COVID-19 infection, therefore, we aimed to determine the effect of current pandemic on the workflow and infection prevention and control strategies of endoscopy units in real-life setting. Methods All members of Hungarian Society of Gastroenterology were invited between 7 and 17 April 2020 to participate in this cross-section survey study and to complete an online, anonymous questionnaire. Results Total of 120 endoscopists from 83 institutes were enrolled of which 35.83% worked in regions with high cumulative incidence of COVID-19. Only 33.33% of them had undergone training about infection prevention in their workplace. 95.83% of endoscopists regularly used risk stratification of patients for infection prior endoscopy. While indications of examinations in low risk patients varied widely, in high-risk or positive patients endoscopy was limited to gastrointestinal bleeding (95.00%), removal of foreign body from esophagus (87.50%), management of obstructive jaundice (72.50%) and biliary pancreatitis (67.50%). Appropriate amount of personal protective equipment was available in 60.85% of endoscopy units. In high-risk or positive patients, surgical mask, filtering facepiece mask, protective eyewear and two pairs of gloves were applied in 30.83%, 76.67%, 90.00% and 87.50% of cases, respectively. Personal protective equipment fully complied with European guideline only in 67.50% of cases. Conclusions Survey found large variability in indications of endoscopy and relative weak compliance to national and international practical recommendations in terms of protective equipment. This could be improved by adequate training about infection prevention.

Diagnostic accuracy and quality of smears obtained by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) are influenced by characteristics of suction and examined organ.Efficiency of EUS-FNA and quality of smears obtained by slow-pull (SP) and standard suction (SS) techniques was prospectively compared in the sampling of pancreatic (SS technique resulted in a higher number of smear pairs both in pancreatic (1.74 vs. 3.19;SP technique yields better quality smears independently from tumors characteristics; however, it shows significant examiner-dependency. SS technique reduces the diagnostic accuracy of sampling in extrapancreatic tumors.

The first anti-TNFα therapy was introduced after an average 7.84 and 9.86 years from diagnosis of Crohn's disease and ulcerative colitis. The first treatment period lasted for 2.64 years; 50% of patients receiving IFX and 46% of patients receiving ADA were in remission at the end of the period. The second treatment period lasted for 4.67 years, 36% of IFX-treated patients and 40% of ADA-treated patients were in remission at the end of the period. 13% and 18% of patients treated by IFX and 4% and 3% of patients treated by ADA experienced infusion reaction during the first and the second treatment period. Primary non-response and loss of response rates were 4% and 10.5% (IFX) and 11.5% and 19% (ADA) during the first treatment period. These rates were 9% and 18% (IFX) and 23% and 10% (ADA) during the second treatment period.Our study confirmed the long-term efficacy and safety of the anti-TNFα therapies. Loss of response rate is lower in our population compared to the literature. Orv Hetil. 2020; 161(47): 1989-1994.

Abstract: Introduction: Transfer is a planned movement of patients and their medical records from one provider to another. Only a few data are available from real life in inflammatory bowel disease patients in this topic. Aim: Our aim was to retrospectively evaluate the results of the transfer of our patients without longitudinal transition. Method: Data of the transferred patients at the University of Szeged were analysed. Patients were diagnosed in paediatric care. Transfer strategy at our departments was detailed medical summary. Results: 59 patients were enrolled in this study. 28.8% of the patients had mild to moderate disease activity and 71.2% was in remission at the time of transfer. Steroid therapy was initiated in 58% of the patients within an average of 9.1 months after the transfer. Anti-tumor necrosis factor therapy was given to 24% of the patients during the paediatric care and to an additional 23% in the adult care within an average of 28 months. Almost 70% of the patients received immunosuppressive therapy during paediatric and adult care. Surgery was required in 17% of the patients within an average 10.7 months after the transfer. Conclusion: Our results revealed that one-third of the paediatric patients have been transferred to adult care in active stage of disease. Shortly after the transfer 58% of the patients required corticosteroids and 17% surgery. Every fifth patient needed biological therapy to be initiated after the transfer. Longitudinal transition may have a potential to decrease the need for therapeutic change and the relatively high rate of surgery. Orv Hetil. 2018; 159(44): 1789–1793.

Abstract: Introduction: In Hungary, a nationwide colorectal screening program is about to be introduced in order to improve the extremely high mortality rate of colorectal cancer (CRC). Aim: The aim of our study was to summarize experiences and assess short-term efficacy of the population-based pilot colorectal screening program in 2015 in Csongrád County, Hungary. Patients and method: Asymptomatic individuals between the ages of 50 and 70 with average risk of colorectal cancer participated in the program that was based on the two-step screening method (i.e. immune fecal blood test and colonoscopy). The short-term efficacy of the screening program was assessed as the change in total CRC incidence and initial tumor stage in the screening year (2015) compared to a control year (2013) in Szeged and its surroundings. Participation rate, positive predictive value of the screening methods and tumor detection rate was assessed. Results: 22,130 individuals were invited, the participation rate was 46.4%. Immune fecal blood test proved to be non-negative in 1,343 cases (13%), screening colonoscopy was performed in 766 of them (7.5%). Total colonoscopy was performed in 711 individuals. Based on the reports, adenoma was detected in 358 (50.3%) and malignancy in 42 (5.9%) individuals. In the background population, the incidence of colon cancer was significantly higher (183 vs. 228; p = 0.026) and was diagnosed at significantly earlier stage (p = 0.002). Lymph node involvement was significantly lower in 2015 (48.3% vs. 37.1%; p = 0.049). Conclusion: The Csongrád county population-based colorectal cancer screening was evidently successful on the short term considering participation rate, and the changes in CRC incidence and stage, thus its national extension is necessary.

Background: Safety data of the ‘real life’ use of an infliximab biosimilar, CT-P13 in inflammatory bowel disease (IBD) are still lacking. Our aim was to assess the frequency and characteristics of infusion reactions during CT-P13 therapy in 13 Hungarian and 1 Czech IBD centres. Methods: Clinical and safety data was registered at fixed appointments. Trough levels and anti-drug antibody (ADA) concentration were measured by ELISA. Association between demographic, clinical, laboratory parameters and infusion reaction rates were evaluated statistically. Results: Three hundred and eighty-four IBD patients were included. Twenty-eight Hungarian IBD patients (9.6%) developed infusion reaction during the treatment, 64.3% of them was previously exposed to anti TNF therapy. No infusion reaction occurred in the Czech population. CT-P13 therapy had to be stopped in 17 patients who developed infusion reaction and was switched to adalimumab in 12 patients. However in 39.3% of patients developing infusion reaction CT-P13 therapy was continued with the use of premedication. Cumulative ADA positivity rates were 8.7%, 19.3%, and 28.0% at weeks 0, 14, and 30. Previous anti-TNF-alpha exposure (30% vs. 3.1%, p

AIM: To evaluate and compare the patients opinion on the two types of anti- TNF-α therapies in a Hungarian cohort of IBD patients. METHODS: This was a prospective, multicentre, questionnaire-based observational study carried out in three Hungarian tertiary centres. From April to September 2014, an anonymous questionnaire was distributed to patients diagnosed with ulcerative colitis (UC) or Crohn’s disease (CD), who have received infliximab (IFX) and/or adalimumab (ADA). The survey focused on the preferences of the two anti-TNF-α therapies on the basis of the efficacy, the administration routes and the side effects. RESULTS: 292 IBD patients, 216 CD, 75 UC and 1 indeterminate colitis patient completed the questionnaire. The mean duration of biological therapy was 1.7 (1 - 7) years. IFX treated patients noticed improvement of symptoms at 4 - 5 weeks while ADA treated patients noticed at 5 - 6 weeks. There was no difference between the patients’ satisfaction regarding the types of anti-TNF-α therapy if they received both. However, subcutaneous administration was preferred by ADA-treated patients previously receiving IFX (p = 0.007) compared to intravenous route and they did not intend to change the mode of therapy (p = 0.040). 90% of the patients, receiving only IFX or ADA were satisfied with their present therapy. The majority of patients (186/292, 63.7%) would not switch therapy. 63 of 291, 22% of the patients reported to have some concern with biological therapy—the majority (32/63, 50.8%) due to fear from side effects. CONCLUSION: Generally, patients preferred and would not change the present anti-TNF-α therapy, however, subcutaneous administration was preferred among those patients who had have experience with both.

Background Budesonide is an oral corticosteroid, which is widely used in moderate-to-severe ulcerative colitis (UC) to obtain and maintain remission in those cases, where 5-aminosalicylic-acid was ineffective. Unlike previous forms of budesonide absorbing from the ileal and ascending colon region, the new-generation budesonide-MMX contains a formula, that allows absorption throughout the whole colon, and therefore in the whole potentially inflamed area in UC. We aimed to evaluate the effects and safety of budesonide-MMX in our UC patients who meet the above mentioned therapeutic demands in a real-life study. Methods We enrolled 22 patients with mild to severe UC in this single-centre prospective study until August of 2019. Patients received 9 mg oral budesonide-MMX once daily until 8 weeks. Laboratory parameters (cholesterol, triglyceride, CRP) and serum hormone levels (parathormone [PTH], dehydroepiandrosterone [DHEA] and cortisol) were monitored before and after the 8-week therapy to follow metabolic and hormonal changes. During these visits, body composition analysis was also performed with InBody 770 machine to observe the adverse steroid effects of budesonide-MMX in respect of body fat mass, body mass index, protein content of the body and bone mineral content. Disease activity was followed by the partial Mayo (pMayo) score. Statistical analysis was performed by paired t-test and Wilcoxon signed-rank test with SigmaPlot 1.25. Results The total of 22 patients (age: 44.4 ± 15.1 years, 6 male and 16 female patients) had received the 2-month budesonide-MMX therapy (2.0 ± 0.3 months). Mean disease duration was 8.3 years. By the end of follow-up, 15 (68.2%) patients experienced remission and 7 patients (31.8%) were primary non-responders. The disease activity decreased significantly from the mean of 3.95 to 1.64 (p < 0.001). No significant changes were observable in case of any body composition analysis parameter. Regarding the laboratory parameters, serum cholesterin level showed a significant increase (p < 0.001), while triglyceride and CRP showed did not show significant changes. Serum cortisol levels were elevated (p < 0.001), while PTH and DHEA showed no significant decrease. Only two patients experienced side effects: one of them hypertonia, headache and acnes, while the other patient experienced mild diarrhoea. One patient had a relapse during the treatment. Conclusion In our study, budesonide-MMX proved to be safe by bringing up a low number of side effects, while more than two-thirds of the patients could reach remission with this short-term therapy. Hormonal changes were not mentionable, although the drug’s effects on serum lipid content have to be examined further.
