Evolocumab in Pediatric Heterozygous Familial Hypercholesterolemia.

BACKGROUND: Evolocumab, a fully human monoclonal antibody directed against proprotein convertase subtilisin-kexin type 9, is widely used in adult patients to lower low-density lipoprotein (LDL) cholesterol levels. Its effects in pediatric patients with heterozygous familial hypercholesterolemia are not known. METHODS: We conducted a 24-week, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of evolocumab in pediatric patients with heterozygous familial hypercholesterolemia. Patients 10 to 17 years of age who had received stable lipid-lowering treatment for at least 4 weeks before screening and who had an LDL cholesterol level of 130 mg per deciliter (3.4 mmol per liter) or more and a triglyceride level of 400 mg per deciliter (4.5 mmol per liter) or less were randomly assigned in a 2:1 ratio to receive monthly subcutaneous injections of evolocumab (420 mg) or placebo. The primary end point was the percent change in LDL cholesterol level from baseline to week 24; key secondary end points were the mean percent change in LDL cholesterol level from baseline to weeks 22 and 24 and the absolute change in LDL cholesterol level from baseline to week 24. RESULTS: A total of 157 patients underwent randomization and received evolocumab (104 patients) or placebo (53 patients). At week 24, the mean percent change from baseline in LDL cholesterol level was -44.5% in the evolocumab group and -6.2% in the placebo group, for a difference of -38.3 percentage points (P<0.001). The absolute change in the LDL cholesterol level was -77.5 mg per deciliter (-2.0 mmol per liter) in the evolocumab group and -9.0 mg per deciliter (-0.2 mmol per liter) in the placebo group, for a difference of -68.6 mg per deciliter (-1.8 mmol per liter) (P<0.001). Results for all secondary lipid variables were significantly better with evolocumab than with placebo. The incidence of adverse events that occurred during the treatment period was similar in the evolocumab and placebo groups. CONCLUSIONS: In this trial involving pediatric patients with familial hypercholesterolemia, evolocumab reduced the LDL cholesterol level and other lipid variables.

Outcomes of Patients With Inflammatory Bowel Diseases Switched From Maintenance Therapy With a Biosimilar to Remicade.

BACKGROUND & AIMS: There is evidence that it is safe and effective for patients with inflammatory bowel diseases (IBD) to switch from maintenance therapy with an original infliximab drug to a biosimilar, but little is known about outcomes of reverse switches and/or multiple switches. We aimed to evaluate the effects of a reverse switch (from a biosimilar to Remicade) in a real-life cohort. METHODS: We performed a prospective observational study of 174 unselected and consecutive patients with IBD (136 with Crohn's disease [CD] and 38 with ulcerative colitis [UC]) who received maintenance therapy with the biosimilar in Hungary. In September 2017, patients were switched from the biosimilar (CT-P13) to Remicade, due to reimbursement policies. In our cohort, 8% (n = 14) patients had been previously exposed to the originator Remicade. We collected clinical and biochemical information from patients at baseline (time of the switch) and 16 and 24 weeks thereafter. Clinical remission was defined as a Crohn's disease activity index <150 points or no fistula drainage, or a partial Mayo score <3 points for patients with UC. Serum drug trough levels and anti-drug antibodies were measured at baseline and week 16. RESULTS: There was no significant difference in the proportion of patients in clinical remission at week 8 before the switch (82.5% with CD and 82.9% with UC), at baseline (80.6% with CD and 81.6% with UC), at week 16 (77.5% with CD and 83.7% with UC), or at week 24 (CD 76.3% with CD and 84.9% with UC) (P = .60 among groups for patients with CD and P = .98 among groups for patients with UC). For all patients, mean serum trough levels of infliximab were 5.33 ± 4.70 µg/mL at baseline and 5.69 ± 4.94 µg/mL at week 16 (P = .71); we did not find significant differences in prevalence of anti-drug antibody at baseline (16.2%) compared with week 16 (16.9%) (P = .87). Four infusion reactions occurred, until week 24 of follow up. There was no difference in outcomes or trough or antidrug antibody levels between patients with or without previous exposure to Remicade. CONCLUSIONS: We collected data from a real-life cohort of patients with CD or UC who were switched from maintenance therapy with a biosimilar to Remicade or were treated with only Remicade. No significant changes were observed in remission, trough levels, or antidrug antibodies in patients switched from the biosimilar to Remicade. No new safety signals were detected.

Co-Administration of Proton Pump Inhibitors May Negatively Affect the Outcome in Inflammatory Bowel Disease Treated with Vedolizumab.

Concomitant medications may alter the effect of biological therapy in inflammatory bowel disease. The aim was to investigate the effect of proton pump inhibitors on remission rates in patients with inflammatory bowel disease treated with the gut-selective vedolizumab. Patients from the Hungarian nationwide, multicenter vedolizumab cohort were selected for post hoc analysis. Primary outcomes were the assessment of clinical response and endoscopic and clinical remission at weeks 14 and 54. Secondary outcomes were the evaluation of the combined effect of concomitant steroid therapy and other factors, such as smoking, on remission. A total of 108 patients were identified with proton pump inhibitor data from 240 patients in the original cohort. Patients on steroids without proton pump inhibitors were more likely to have a clinical response at week 14 than patients on concomitant PPI (95% vs. 67%, p = 0.005). Non-smokers with IBD treated with VDZ were more likely to develop a clinical response at week 14 than smokers, particularly those not receiving PPI compared with patients on co-administered PPI therapy (81% vs. 53%, p = 0.041, and 92% vs. 74%, p = 0.029, respectively). We found that the use of PPIs in patients treated with VDZ may impair the achievement of response in certain subgroups. Unnecessary PPI prescriptions should be avoided.

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. Patient and disease characteristics, treatment history, clinical disease activity (Harvey Bradshaw Index (HBI)), biomarkers, and endoscopic activity (Simple Endoscopic Score for Crohn's Disease (SES-CD)) were collected for three-years' time. A total of 148 patients were included with an overall 48.9% of complex behavior of the Crohn's disease and 97.2% of previous anti-TNF exposure. The pre-induction remission rates were 12.2% (HBI), and 5.1% (SES-CD). Clinical remission rates (HBI) were 52.2%, 55.6%, and 50.9%, whereas criteria of an endoscopic remission were fulfilled in 14.3%, 27.5%, and 35.3% of the subjects at the end of the first, second, and third year, respectively. Dose intensification was high with 84.0% of the patients on an 8-weekly and 29.9% on a 4-weekly regimen at the end of year 3. Drug sustainability was 76.9% during the follow-up period with no serious adverse events observed. Ustekinumab in the long-term is an effective, sustainable, and safe therapeutic option for Crohn's disease patients with severe disease phenotype and high previous anti-TNF biological failure, requiring frequent dose intensifications.

Is there any association between impaired health-related quality of life and non-adherence to medical therapy in inflammatory bowel disease?

OBJECTIVES: Inflammatory bowel diseases (IBD) have a huge impact on the patients' lives and require continuous medication and long-term medical follow-up. The Short Form Health Survey (SF-36) is a commonly used questionnaire measuring health-related quality of life (HRQOL). Our aim was to evaluate whether HRQOL influences medication adherence and vice versa in IBD patients, and to find relationships between demographic parameters, therapeutic modalities and non-adherence or HRQOL. PATIENTS AND METHODS: Five hundred ninety-two IBD patients treated at six Hungarian tertiary centers were enrolled. Patients completed the SF-36 questionnaire and a medication adherence report scale during their visits. The associations between demographic parameters, HRQOL, different kinds of therapies and non-adherence were analyzed. RESULTS: The most affected dimension was physical functioning and least affected were the social functions. About 42.7% of the patients revealed their HRQOL to be acceptable. About 74.6% of the patients believed that the prescribed medications actually improved their HRQOL. Diarrhea was the most common and most severe symptom during the course of the disease. Non-adherence was reported in 13.4% of the patients. 'Forgetting to take the medication' was the main reason for non-adherence in 67.6% of the cases. Medication adherence was significantly higher among nonsmoker patients, and also in the case of immunomodulator therapy. There was no association between the sum of HRQOL and different subscores and non-adherence. CONCLUSION: Inflammatory bowel disease is associated with low HRQOL, which is not affected by drug therapy. The impaired quality of life in IBD is mainly influenced by the disease itself.

[Introduction of a quality index in a Hungarian endoscopy unit]. / Minoségi indikátor bevezetése egy magyar gasztroenterológiai endoszkópos laboratórium munkájába.

UNLABELLED: The quality of endoscopic examinations substantially determines their value. In developed countries, Continuous Quality Management is used to improve it permanently. In Hungary there is no example for measuring quality in the field of gastrointestinal endoscopy. AIM: The measurement and improvement of quality of endoscopy applying completeness index (cecum intubation rate) during colonoscopy. PATIENTS AND METHODS: The authors defined base values retrospectively from 841 colonoscopy reports, performed in the last quarter of the year, before starting the project. The next two years (3160 colonoscopy in 2009 and 3167 in 2010) every three months they calculated the cecum intubation rate for each endoscopist. RESULTS: The cecum intubation rate was 81.6% in the base period. When the authors excluded examinations with poor preparations and those with a previously unknown stenosis that prevented the total colonoscopy, the adjusted cecal intubation rate was 90.9%. In the next 2 years, the cecum intubation rate was 84.2% and 85.7% (p = 0.0394), while adjusted cecum intubation rate proved to be 92.3% and 92.6% (p = 0.381 NS) for the whole endoscopy unit. Of the 14 endoscopists only 6 reached an adjusted cecum intubation rate of 90%, but in the second year of the project 10 of them reached this rate and only one endoscopist remained below 87%. The endoscopists performing more than 100 colonoscopies per year had better adjusted cecum intubation rate (base 91.2%; 92.7% and 93.1% during the 2 project years) compared to those with less than 100 colonoscopies per year (base, 86.7%; project period, 85.5 and 89%). CONCLUSIONS: The evaluation and publicity of the cecal intubation rate resulted in an improvement of the quality of colonoscopy. The authors also presented that endoscopists performing more than 100 colonoscopies per year have better endoscopic quality.

Non-medical switch from the originator to biosimilar and between biosimilars of adalimumab in inflammatory bowel disease - a prospective, multicentre study.

INTRODUCTION: Clinical data on the efficacy and safety of non-medical switch between adalimumab(ADA) biosimilars are limited. AIMS: The aim of this study was to evaluate medium-term clinical efficacy, drug sustainability and safety comparing non-medical switches from the originator to biosimilar ADA, and between ADA biosimilars. METHODS: 276 consecutive patients on maintenance ADA therapy (n = 205 Crohn's disease, n = 71 ulcerative colitis) were included. Data on clinical efficacy, biomarkers and adverse events were collected at four time points: 8-12 weeks prior switch, at baseline/switch, 8-12 weeks and 20-24 weeks after switch. Drug survival was evaluated after a median 40(IQR:35-42) weeks follow-up. RESULTS: A total 174 patients underwent a non-medical switch from the originator to a biosimilar, and 102 patients had a biosimilar-to-biosimilar switch. No significant difference was found in clinical remission rates at any time point in patients switching from originator to biosimilar(87.3%/88.5%/86.5%/85.7%) or biosimilar to biosimilar(74.5%/78.4%/85.3%/79.8%). Mean C-reactive protein levels remained unchanged in both cohorts(p = 0.856 and p = 0.525). Drug survival was similar between the two cohorts with a probability of 91.6%(SE: 2.2) and 87.0%(SE:3.4) to stay on drug after 40 weeks(log-rank:0.96; p = 0.327). Five cases of injection related adverse events were reported. CONCLUSION: Clinical benefit was sustained following non-medical switch from originator to biosimilar, or between biosimilars in adalimumab treated IBD patients.

Ustekinumab is associated with superior treatment persistence but not with higher remission rates versus vedolizumab in patients with refractory Crohn's disease: results from a multicentre cohort study.

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 < 0.0001). The drug type was predictive of clinical SFR at week 52 [p = 0.011, odds ratio (OR) = 2.39 with UST]. Drug failure rates were higher for VDZ than those for UST (PNR rates: 21.54% and 4.97%, respectively, p < 0.001, OR = 8.267, p = 0.001). LOR and escalations were more common during UST treatment (61.5% versus 36.9%, p < 0.001; 64.2% versus 23.1%, p < 0.001). Hospital and surgical admission rates did not differ significantly. Only one adverse event occurred with VDZ at week 20, which led to drug cessation. 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.

Clinical efficacy, drug sustainability and serum drug levels in Crohn's disease patients treated with ustekinumab - A prospective, multicenter cohort from Hungary.

INTRODUCTION: Although efficacy of ustekinumab (UST) has been demonstrated through randomized trials, data from real-life prospective cohorts are still limited. Our aim was to evaluate clinical efficacy, drug sustainability, dose intensification and results from therapeutic drug monitoring in UST treated patients with Crohn's disease (CD) using a prospective, nationwide, multicenter cohort. METHODS: Patients from 10 Inflammatory Bowel Disease centers were enrolled between 2019 January and 2020 May. Patient demographics, disease phenotype, treatment history, clinical disease activity (Crohn's Disease Activity Index(CDAI), Harvey Bradshaw Index(HBI)), biomarkers, and serum drug levels were obtained. Evaluations were performed at week8 (post-induction), w16-20, w32-36, and w52-56 follow-up visits. RESULTS: A total of 142 patients were included [57.4% female; complex disease behavior (B2/B3):48%, previous anti-TNF exposition:97%]. Clinical response and remission rates after induction(w8) were 78.1% and 57.7% using CDAI, and 82.5% and 51.8% based on HBI scores. The one-year clinical remission rate was 58%/57.3%(CDAI/HBI). Composite clinical and biomarker remission (CDAI<150 and C-reactive protein<10 mg/L) rates were 35.4%; 33.3%; 38.6% and 36.6% at w8/w16-20/w32-36 and w52-56. Drug sustainability was 81.9%(standard deviation(SD): 3.4) at 1 year(1y). Probability of dose intensification was high and introduced early, 42.2%(SD:4.2) at ~w32 and 51.9%(SD:4.4%) at 1y. CONCLUSION: Ustekinumab showed favorable drug sustainability and clinical efficacy in a patient population with severe disease phenotype and previous anti-tumor necrosis factor (anti-TNF) failure, however frequent dose intensification was required.

[Predictors of efficacy, mucosal healing and dose intensification during the first year of adalimumab therapy in patients with luminal and fistulizing Crohn's disease. National data from Hungary]. / A klinikai hatékonyság, a nyálkahártya-gyógyulás és a dózisemelés prediktorai az adalimumabkezelés elso évében Crohn-betegségben szenvedo betegekben Magyarországon.

UNLABELLED: Adalimumab is a fully human monoclonal antibody targeting tumor necrosis factor with proven efficacy in the treatment of Crohn's disease in clinical trials. The aim of the present study was to investigate the predictors of medium term clinical efficacy and mucosal healing during adalimumab therapy in patients with Crohn's disease in specialized centers approved for biological therapy in Hungary. METHODS: Data of 201 Crohn's disease patients were prospectively captured (male/female: 112/89, median age: 24 years, duration: 8 years). Previous infliximab therapy was given in 97 (48.3%) patients, concomitant steroids in 41.3% and azathioprine in 69.2% (combined: 26.4%) of patients. RESULTS: Overall clinical response and remission rates at 24 and 52 weeks were 78% and 52%, and 69.4% and 44.4%, respectively. Endoscopic improvement and healing was achieved in 43.1% and 23.6%, respectively. In a logistic regression model, clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression at induction, shorter disease duration and smoking were identified as independent predictors for 12-month clinical outcome, while normalized C-reactive protein at week 12, clinical remission at week 24, frequency of previous relapses and smoking were associated to endoscopic improvement/healing. Dose intensification to weekly dosing was needed in 16.4%. Parallel azathioprine therapy and clinical remission at week 12 was inversely associated to dose escalation to weekly dosing. CONCLUSION: Clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression, luminal disease and smoking are predictors for medium term clinical efficacy/mucosal healing during adalimumab therapy, while parallel azathioprine therapy may decrease the probability for dose escalation.

Colesevelam hydrochloride: efficacy and safety in pediatric subjects with heterozygous familial hypercholesterolemia.

OBJECTIVE: Evaluate the efficacy and safety of colesevelam hydrochloride in children with heterozygous familial hypercholesterolemia (heFH). STUDY DESIGN: This was a randomized, double-blind, 41-site study in 194 children aged 10 to 17 years (inclusive) with heFH (statin-naïve or on a stable statin regimen). After a 4-week stabilization period (period I), subjects were randomized 1:1:1 to placebo, colesevelam 1.875 g/d, or colesevelam 3.75 g/d for 8 weeks (period II). All then received open-label colesevelam 3.75 g/d for 18 weeks (period III), with follow-up 2 weeks later. The primary endpoint was percent change in low-density lipoprotein (LDL)-cholesterol from baseline to week 8. Secondary endpoints included percent change in other lipoprotein variables, including non-high-density lipoprotein (non-HDL)-cholesterol. Adverse events were also evaluated. RESULTS: At week 8, a significant difference from baseline in LDL-cholesterol was reported with colesevelam 1.875 g/d (-6.3%; P = .031) and colesevelam 3.75 g/d (-12.5%; P < .001) compared with placebo. Significant treatment effects were also reported for total cholesterol (-7.4%), non-HDL-cholesterol (-10.9%), HDL-cholesterol (+6.1%), apolipoprotein A-I (+6.9%), and apolipoprotein B (-8.3%) and a nonsignificant effect for triglycerides (+5.1%) with colesevelam 3.75 g/d compared with placebo at week 8. These treatment effects were maintained during period III. CONCLUSIONS: Colesevelam significantly lowered LDL-cholesterol levels in children with heFH.

[Treatment adherence and use of complementary and alternative medicine in patients with inflammatory bowel disease]. / A terápiás adherencia, valamint a komplementer és alternatív gyógymódok használata gyulladásos bélbetegek kezelésében.

UNLABELLED: Previous studies have suggested an increasing use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). Furthermore, a significant number of IBD patients fail to comply with treatment. The aim of our study was to evaluate the prevalence of non-adherence the use of CAM in Hungarian patients with IBD. METHODS: A total of 655 consecutive IBD patients (Crohn's disease [CD]: 344, age: 38.2 + or - 12.9 years; ulcerative colitis [UC]: 311, age: 44.9 + or - 15.3 years) were interviewed during the visit at specialists by self-administered questionnaire including demographic and disease-related data, as well as items analyzing the extent of non-adherence and CAM use. Patients taking more then 80% of each prescribed medicine were classified as adherent. RESULTS: The overall rate of self reported non-adherence (CD: 20.9%, UC: 20.6%) and CAM (CD: 31.7%, UC: 30.9%) use was not different between CD and UC. The most common causes of non-adherence were: forgetfulness (47.8%), too many/unnecessary pills (39.7%), being afraid of side effects (27.9%) and too frequent dosing. Most common forms of CAM were herbal tee (47.3%), homeopathy (14.6%), special diet (12.2%), and acupuncture (5.8%). In CD, disease duration, date of last follow-up visit, educational level and previous surgeries were predicting factors for non-adherence. Alternative medicine use was associated in both diseases with younger age, higher educational level and immunosuppressant use. In addition, CAM use in UC was more common in females and in patients with supportive psychiatric/psychological therapy. CONCLUSIONS: Non-adherence and CAM use is common in patients with IBD. Special attention should be paid to explore the identified predictive factors during follow-up visits to improve adherence to therapy and improving patient-doctor relationship.

Anti-TNF dose escalation and drug sustainability in Crohn's disease: Data from the nationwide administrative database in Hungary.

BACKGROUND: A significant percentage of patients receiving anti-tumor necrosis factor alpha (anti-TNFα) agents lose clinical response over time. This study aims to provide representative real-world data on anti-TNFα drug sustainability, prevalence and predictors of anti-TNFα dose escalation. METHODS: In this nationwide, retrospective study, patients receiving infliximab or adalimumab therapy between 2013 and 2016 were included using the administrative claims database of the Hungarian National Health Insurance Fund. Demographic characteristics, drug sustainability, dose escalation, use of parallel medications were analyzed. RESULTS: 476 infliximab and 397 adalimumab patients were included. Dose escalation was observed in 7%, 9% and 22% of patients receiving originator/biosimilar infliximab and adalimumab during the complete follow-up, respectively. Dose escalation was associated with shorter disease duration (OR = 1.75, p = 0.026) and corticosteroid use. Drug retention rates were 62.7%, 72.3%, 75.4% after 1 year follow-up for Remicade®, Inflectra® and Humira®, which decreased to 38.3% and 52.1% for Remicade® and Humira® at 3 years. Drug sustainability was affected by steroid use prior biologic initiation in adalimumab treated patients (HR = 2.04, p < 0.001), while in infliximab treated patients dose escalation (HR = 0.51, p = 0.02) and gender (HR = 1.39, p = 0.033) were predictors of treatment discontinuation. CONCLUSION: Dose escalation rates were lower in this real-world administrative database study for both adalimumab and infliximab compared to published data. Drug retention rates were overall satisfactory, with no apparent difference between the legacy and biosimilar infliximab.

Epidemiology, mortality and prevalence of colorectal cancer in ulcerative colitis patients between 2010-2016 in Hungary - a population-based study.

BACKGROUND: The incidence and prevalence of ulcerative colitis (UC) varies geographically. The risk of colorectal cancer (CRC) and possibly some other malignancies is increased among patients with UC. It is still debated if patients with UC are at a greater risk of dying compared with the general population. Our aim was to describe the epidemiology and mortality of the Hungarian UC population from 2010 to 2016 and to analyze the associated malignancies with a special focus on CRC. METHODS: This is an observational, descriptive, epidemiological study based on the National Health Insurance Fund social security databases from 2010 to 2016. All adult patients who had at least two events in outpatient care or at least two medication prescriptions, or at least one inpatient event with UC diagnosis were analyzed. Malignancies and CRC were defined using ICD-10 codes. We also evaluated the survival of patients suffering from UC compared with the general population using a 3 to 1 matched random sample (age, gender, geography) from the full population of Hungary. RESULTS: We found the annual prevalence of UC 0.24-0.34%. The incidence in 2015 was 21.7/100 000 inhabitants. Annual mortality rate was 0.019-0.023%. In this subpopulation, CRC was the most common cancer, followed by non-melanotic skin and prostate cancer. 8.5% of the UC incident subpopulation was diagnosed with CRC. 470 (33%) of the CRC patients died during the course of the study (25% of all deaths were due to CRC), the median survival was 9.6 years. UC patients had significantly worse survival than their matched controls (HR = 1.65, 95% CI: 1.56-1.75). SUMMARY: This is the first population-based study from Eastern Europe to estimate the different malignancies and mortality data amongst Hungarian ulcerative colitis patients. Our results revealed a significantly worse survival of patients suffering from UC compared to the general population.

Epidemiological data and utilization patterns of anti-TNF alpha therapy in the Hungarian ulcerative colitis population between 2012-2016.

Background: Anti-TNF therapy is efficacious in the maintenance of remission in ulcerative colitis (UC); however, long-term data on real-life use of these agents are lacking.Methods: This observational, retrospective, epidemiological study using the National Health Insurance Fund social security database aimed to understand patient characteristics and therapeutic patterns of anti-TNF therapy. Data of adult Hungarian, UC patients treated with anti-TNF agents (IFX-infliximab, ADA-adalimumab) between 2012 and 2016 were analyzed.Results: Five hundred and sixty-eight UC patients were identified. Approximately 70-80% of the patients reached maintenance therapy. A large proportion of patients stopped therapy after 10 to 12 months due to the reimbursement policy. Corticosteroid use decreased significantly after the initiation of biological therapy. The dose-escalation rate was 19.8% for ADA and 10.9% for IFX, respectively, and was performed earlier along the treatment timeline for patients on ADA. In the present study, the rate of primary non-response (PNR) was 11.6% and the rate of secondary loss of response (LOR) was 36.5%.Summary: Treatment length is in correspondence with the Hungarian reimbursement policies. The mandatory stop of treatment in the reimbursement policy is suboptimal in UC patients requiring biological therapy. The corticosteroid-sparing effect of biological therapy was demonstrated.

Real-life efficacy of vedolizumab on endoscopic healing in inflammatory bowel disease - A nationwide Hungarian cohort study.

Background: GEMINI trials demonstrated the therapeutic efficacy of vedolizumab (VDZ) in Crohn's disease (CD) and ulcerative colitis (UC).Research design and methods: Aim of this study was to determine the real-life effectiveness of VDZ on endoscopic healing in the Hungarian nationwide cohort of inflammatory bowel disease (IBD) patients based on the changes on clinical and endoscopic scores. Every adult IBD patient in the country (121 UC and 83 CD) who completed the short-term VDZ therapy was enrolled, of which 72 UC and 52 CD patients could complete the long-term therapy.Results: The rates of endoscopic healing were substantially higher in UC compared with CD patients during the short- and long-term therapy (52.9% vs. 21.7%, p < 0.0001, and 51.4% vs. 21.2%, p = 0.015, respectively). In CD, the rate of endoscopic healing was lower at week 14 compared with week 22 (14.5% vs. 37.0%, p = 0.026). Prior anti-TNF-α therapy (88.73%) was not associated with a significant decrease in therapeutic response. The average disease duration was significantly lower in CD patients achieving endoscopic healing at week 52 (11.75 vs. 5.27 years, p = 0.007).Conclusions: VDZ therapy is an effective therapeutic option in anti-TNF-α refractory IBD. However, the endoscopic healing rate was substantially lower and showed a significant delay in CD compared with UC.

Efficacy and safety of infliximab induction therapy in Crohn's Disease in Central Europe--a Hungarian nationwide observational study.

BACKGROUND: Infliximab (IFX) has proven to be an effective addition to the therapeutic arsenal for refractory, fistulizing, and steroid dependent Crohn's disease (CD), with efficacy in the induction and maintenance of clinical remission of CD. Our objective in this study is to report the nationwide, multicenter experience with IFX induction therapy for CD in Hungary. METHODS: During a 6-year-period, beginning in 2000, a total of 363 CD patients were treated with IFX as induction therapy (5 mg/kg IFX infusions given at week 0, 2 and 6) at eleven centers in Hungary in this observational study. Data analysis included patient demographics, important disease parameters and the outcome of IFX induction therapy. RESULTS: Three hundred and sixty three patients (183 women and 180 men) were treated with IFX since 2000. Mean age was 33.5 +/- 11.2 years and the mean duration of disease was 6.7 +/- 6.1 years. The population included 114 patients (31.4%) with therapy-refractory CD, 195 patients (53.7%) with fistulas, 16 patients (4.4%) with both therapy-refractory CD and fistulas, and 26 patients (7.2%) with steroid dependent CD. Overall response rate was 86.2% (313/363). A higher response rate was observed in patients with shorter disease duration (p = 0.05, OR:0.54, 95%CI:0.29-0.99) and concomitant immunosuppressant therapy (p = 0.05, OR: 2.03, 95%CI:0.165-0.596). Concomitant steroid treatment did not enhance the efficacy of IFX induction therapy. Adverse events included 34 allergic reactions (9.4%), 17 delayed type hypersensitivity (4.7%), 16 infections (4.4%), and 3 malignancies (0.8%). CONCLUSION: IFX was safe and effective treatment in this cohort of Hungarian CD patients. Based on our experience co-administration of immunosuppressant therapy is suggested in patients receiving IFX induction therapy. However, concomitant steroid treatment did not enhanced the efficacy of IFX induction therapy.

The 3'UTR NFKBIA variant is associated with extensive colitis in Hungarian IBD patients.

PURPOSE: In previous studies the NFKBIA 3'UTR (untranslated region) AA genotype was associated with Crohn's disease (CD), while the NFKB1-94ins/delATTG mutation increased the risk for ulcerative colitis (UC). The aim of our study was to investigate these two polymorphisms and patients' response to medical therapy and/or disease phenotype in Hungarian inflammatory bowel disease (IBD) patients. METHODS: NFKBIA 3'UTR- and NFKB1-94ins/delATTG polymorphisms were investigated in 415 unrelated IBD patients (CD: 266 patients, mean age 35.2 +/- 12.1 years, duration 8.7 +/- 7.5 years; UC patients: 149, mean age 44.4 +/- 15.4 years, duration 10.7 +/- 8.9 years) and 149 controls by PCR-restriction fragment length polymorphism (RFLP) analysis. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: The NFKBIA 3'UTR and NFKB1-94ins/delATTG genotypes and allele frequencies were not significantly different among IBD and controls. In patients with UC, the 3'UTR GG genotype was associated with extensive colitis (55.3 vs. 29.4%, odds ratio 2.97, 95% confidence interval 1.45-6.08). The presence of variant alleles did not predict response to steroids, infliximab, or need for surgery. CONCLUSIONS: The NFKBIA 3'UTR GG genotype was associated with an increased risk for extensive colitis in Hungarian patients. In contrast, variant alleles did not predict response to medical therapy or need for surgery.

[Self-expanding metal stents for palliation of malignant oesophageal obstruction]. / Malignus nyelôcsô-obstructio palliatiója öntáguló fémsztent behelyezésével.

BACKGROUND: Malignant oesophageal stenosis can be caused by cancer of the oesophagus, gastric cardia, lungs, mediastinum or, rarely, breast. Most of these cases are inoperable due to advanced stage of the disease, comorbidities or age of the patients; and palliative treatment can be applied only. The quality of life is mostly determined by the extent of dysphagia. Several methods are available to palliate dysphagia. Hereby, the authors review their results with palliation of malignant oesophageal obstruction applying self-expanding metal stents. PATIENTS AND METHODS: 68 endoscopic stent implantations were performed in 64 patients (15 female and 49 male) with malignant dysphagia between 2003 and 2008. After radiological investigations, distally deployed covered stents with or without an antireflux valve were placed, depending on the localization of the tumour. In one patient with a stenosis localized in the upper third of the oesophagus a proximally deployed covered stent was used. The aim was to re-establish oral nutrition and cover possible fistulas. RESULTS: Significant improvement of swallowing was detected in every patient. Average dysphagia score has improved from 3.2 to 1.7. Technical difficulties during stenting occurred in a relatively low percentage of patients only (2 in 68; i.e. 2.94%). Fistulas were covered in every case. Early stent migration (<7 days) happened in one case. One patient suffered non-fatal myocardial infarction two days after stent placement. In 5 cases tumour in- and overgrowth, in 4 cases bleeding was seen as late complications. Oesophago-tracheal fistula was noted in three patients after stent implantation. Late stent migration (>7 days) occurred in two patients. Re-stenting was necessary in four cases, while three patients needed an upper GI endoscopy for cleansing the stent caused by food obstruction. CONCLUSIONS: According to our data self-expanding metal stents are highly effective and safe for improving dysphagia. Stent-related complications are relatively rare. This method is highly recommended for palliation of malignant dysphagia.
