Comparison of therapeutic efficacy and treatment costs of self-expandable metal stents and plastic stents for management of malignant biliary obstruction.

BACKGROUND: According to the European Society of Gastrointestinal Endoscopy guidelines, self-expandable metal stents (SEMSs) are preferable to plastic stents (PSs) in the management of pancreatic cancer, regardless of cancer stage. The aim of this study was to compare the therapeutic efficacy and treatment costs of SEMS and PS in the management of malignant biliary obstruction. METHODS: One hundred and thirty-five patients who underwent endoscopic stent placement were retrospectively enrolled and divided into PS (41 patients), primary SEMS (39 patients) and secondary SEMS (55 patients) groups. We determined the technical and functional success rate, stent patency, and cumulative treatment cost. RESULTS: A total of 111 SEMSs and 153 PSs were placed with similar technical (100% vs. 98.69%) and functional success rate (90.10% vs. 86.27%) but with different stent patency (10.28 vs. 22.16 weeks; p < 0.001). Multiple PS implantations and larger stent diameter increased the length of stent patency compared to 7-Fr PSs (10.88 vs. 10.55 vs. 7.63 weeks, respectively). The cumulative treatment cost of patients with different survival times did not differ significantly between groups, however, among patients surviving 2-4 months it was higher in PS group than primary SEMS and secondary SEMS groups (2888€ vs. 2258€ vs. 2144€, respectively, p = 0.3369) due to increased number of biliary reintervention (2.08 ± 1.04 vs. 1.20 ± 0.42 vs. 1.50 ± 0.53; p < 0.0274) and longer hospital stay (15.77 ± 10.14 vs. 8.70 ± 7.70 vs. 8.50 ± 6.17 days, p = 0.0527). CONCLUSIONS: In view of treatment costs, the consequences of illness, and the processes of the health care system, SEMS implantation is recommended regardless of patients' life expectancy.

Effect of COVID-19 pandemic on workflows and infection prevention strategies of endoscopy units in Hungary: a cross-sectional survey.

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.

Efficacy, tolerability and safety of a split-dose bowel cleansing regimen of magnesium citrate with sodium picosulfate - a phase IV clinical observational study.

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<0.0001), urea (4.86±1.37 vs. 3.84±1.43 mmol/L, p<0.0001) and creatinine (male: 81.07±16.02 vs. 84.54±15.11 µmol/L; female: 69.32±12.22 vs. 72.96±12.11 µmol/L, p<0.0001) levels during the colonoscopy preparation. However, the number of patients with values outside of the normal range increased significantly only in the case of serum urea (3.95% vs. 26.97%, p<0.0001). CONCLUSION: Magnesium citrate with sodium picosulfate is outstandingly effective, well tolerated and a safe agent in colonoscopy preparation. It caused significant, but non-clinically relevant changes in serum electrolytes levels and renal function.

Slow-pull technique yields better quality smears: prospective comparison of slow-pull and standard suction techniques of endoscopic ultrasound-guided fine-needle aspiration.

BACKGROUND: 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. AIMS AND METHODS: 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 (N = 56) and extrapancreatic (N = 145) tumors. RESULTS: SS technique resulted in a higher number of smear pairs both in pancreatic (1.74 vs. 3.19; p < 0.001) and extrapancreatic tumors (1.62 vs. 3.28; p < 0.001); however, it decreased the proportion of diagnostic smears (46.69% vs. 36.52%; p = 0.002 and 49.17% vs. 30.67%; p < 0.001) and increased the bloodiness (1.51 vs. 2.07; p < 0.001 and 1.48 vs. 2.05; p < 0.001). In pancreatic cancers, no difference was observed in terms of diagnostic accuracy (81.38% vs. 83.45%) and cellularity (1.44 vs. 1.27; p = 0.067); however, they were substantially higher in extrapancreatic tumors using SP technique (71.41% vs. 60.71% and 1.34 vs. 0.77; p < 0.001). Only SP technique resulted in a significant difference between examiners in terms of technical success rate and quality of smears without any decrease of diagnostic accuracy. CONCLUSIONS: 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.

Efficacy of the population-based pilot colorectal cancer screening, Csongrád county, Hungary, 2015

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 population- based 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.

Prospective comparison of slow-pull and standard suction techniques of endoscopic ultrasound-guided fine needle aspiration in the diagnosis of solid pancreatic cancer.

BACKGROUND: The usage of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for the diagnosis of solid pancreatic cancer is increasing, however mainly retrospective studies are available about the detailed methods of sampling. METHODS: To compare prospectively the diagnostic yield of EUS-FNA samples obtained with slow-pull (SP) and with standard suction technique (SS). RESULTS: EUS-FNA sampling was diagnostic in 72 of 92 cases (78.3%). Diagnostic yield was 67.4% in the SS and 65.2% in the SP group. The number of smear pairs (1.84 vs. 3.56; p < 0.001) and blood contamination (1.50 vs. 2.19; p < 0.001) were significantly higher in the SS group, which resulted in lower rate of diagnostic samples (41.8% vs. 30.0%; p = 0.003). There was no difference in the cellularity (1.58 vs. 1.37; p = 0.2554), or in the sensitivity and specificity in the identification of malignancy between SP and SS subgroups (69.9, 100% vs. 73.5, 100%). Histological samples were obtained in 60 cases (with SP: 49 cases; with SS: 46 cases). There was no difference in the diagnostic yield of histological samples between the groups (63 and 58.7%). CONCLUSION: The diagnostic yield, the cellularity of smears and the rate of acquiring sufficient histological material are similar in the SP and SS group, but due to lower bloodiness and decreased number of slides, the pathological diagnosis is faster and more cost-effective.

How disease extent can be included in the endoscopic activity index of ulcerative colitis: the panMayo score, a promising scoring system.

BACKGROUND: Colonoscopy plays crucial role in the establishment of the diagnosis, management and follow-up of ulcerative colitis (UC). None of the currently widely used endoscopic scores consider disease extent, and therefore do not correlate with the real severity of UC. Our aim was to assess the accuracy of a new score, the Pancolonic Modified Mayo Score that can reflect not only the severity, but the extent of active UC. METHODS: One hundred and four UC patients were enrolled in this prospective study. The Endoscopic Mayo Scores of the involved area of the five colorectal segments were added; furthermore, the sum was multiplied by 3 in case of eMayo ≥2 (range 0 [normal] to 45 [most severe]) to obtain the Pancolonic Modified Mayo Score (panMayo) in order to clearly distinguish the active and inactive disease. We analysed the correlation of panMayo Score with eMayo and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and complicated disease outcome. We compared the endoscopic indices with serum and faecal inflammatory parameters and Riley Score. RESULTS: The panMayo Score correlated with eMayo and UCEIS. Every endoscopic score showed correlation with Riley Score, CRP, haemoglobin, haematocrit, serum iron, faecal MMP-9 and calprotectin and also predicted a complicated disease outcome. Only panMayo score correlated exclusively with the extent of UC. CONCLUSIONS: We suggest that this new score gives additional information about disease extent besides disease activity with a strong correlation with laboratory parameters of inflammation and with the other widely used endoscopic indices.

[Transfer of care of adolescent inflammatory bowel disease patients without longitudinal transition. Lesson from 10 years experiences]. / Gyulladásos bélbetegségben szenvedo gyermekek kezelésének átadása felnottszakrendelésre. 10 éves tapasztalataink összegzése.

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.

Drug persistence and need for dose intensification to adalimumab therapy; the importance of therapeutic drug monitoring in inflammatory bowel diseases.

BACKGROUND: Therapeutic drug monitoring (TDM) aid therapeutic decision making in patients with inflammatory bowel disease (IBD) who lose response to anti-TNF therapy. Our aim was to evaluate the frequency and predictive factors of loss of response (LOR) to adalimumab using TDM in IBD patients. METHODS: One hundred twelve IBD patients (with 214 TDM measurements, CD/UC 84/28, male/female 50/62, mean age CD/UC: 36/35 years) were enrolled in this consecutive cohort from two referral centres in Hungary. Demographic data were comprehensively collected and harmonized monitoring strategy was applied. Previous and current therapy, laboratory data and clinical activity were recorded at the time of TDM. Patients were evaluated either at the time of suspected LOR or during follow-up. TDM measurements were determined by commercial ELISA (LISA TRACKER, Theradiag, France). RESULTS: Among 112 IBD patients, LOR/drug persistence was 25.9%/74.1%. The cumulative ADA positivity (>10 ng/mL) and low TL (<5.0 µg/mL) was 12.1% and 17.8% after 1 year and 17.3% and 29.5% after 2 years of adalimumab therapy. Dose intensification was needed in 29.5% of the patients. Female gender and ADA positivity were associated with LOR (female gender: p < 0.001, OR:7.8 CI 95%: 2.5-24.3, ADA positivity: p = 0.007 OR:3.6 CI 95%: 1.4-9.5). CONCLUSIONS: ADA development, low TL and need for dose intensification were frequent during adalimumab therapy and support the selective use of TDM in IBD patients treated with adalimumab. ADA positivity and gender were predictors of LOR.

[Efficacy of the population-based pilot colorectal screening program. Hungary, Csongrád county, 2015]. / Populációalapú "pilot" colorectalis rákszurés eredményessége. Csongrád megye, 2015.

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.

A pilot study on faecal MMP-9: a new noninvasive diagnostic marker of colorectal cancer.

BACKGROUND: Colorectal cancer (CRC) is one of the leading malignancies worldwide, therefore cheap noninvasive screening methods are of great importance. Matrix-metalloproteinase-9 (MMP-9) has a role in the progression of CRC, and its level is elevated in tumour biopsies. Faecal MMP-9 levels are increased in active ulcerative colitis patients, but in CRC patients, they have never been measured. We aimed to assess the faecal MMP-9 levels in patients undergoing total colonoscopy according to endoscopic and histological diagnosis. METHODS: One hundred and nine patients provided faecal samples for MMP-9 analysis. A total colonoscopy was performed; suspicious lesions were evaluated by histology. Faecal MMP-9 levels were measured by ELISA. RESULTS: The number of patients allocated to different groups were: negative/diverticulosis: 34 (referred to as controls); hyperplastic polyps: 15; adenomas: 32 (22 at high risk); and CRC: 28. Faecal MMP-9 was significantly increased in CRC compared with all other groups (P<0.001). Faecal MMP-9 was suitable to distinguish CRC patients from controls (sensitivity: 89.3%; specificity: 91.2%). By means of a lower cutoff level, faecal MMP-9 identified high-risk adenomas besides CRC (sensitivity: 76%; specificity: 85.3%). This lower cutoff level screened 59% of high-risk adenomas. CONCLUSIONS: Faecal MMP-9 may be a promising new noninvasive marker in CRC.

Diagnostic Accuracy of Five Different Fecal Markers for the Detection of Precancerous and Cancerous Lesions of the Colorectum.

Background. Colorectal cancer (CRC) is the second deadliest malignancy worldwide. This study aimed to compare the diagnostic accuracy of different fecal markers in the detection of colorectal adenomas and cancer. Methods. Stool samples of patients referred to colonoscopy were collected for the analysis of tumor M2 pyruvate kinase (M2PK), human hemoglobin (Hb), hemoglobin/haptoglobin (Hb/Hp) complex, fecal calprotectin (FC), and matrix metalloproteinase-9 (MMP-9). Results. Sensitivity and specificity of M2PK for adenomas sized > 1 cm were 60% and 67.5% and for CRC were 94.7% and 67.5%. Sensitivity and specificity of iFOBT for adenomas sized ≥ 1 cm were 80% and 72.5% and for CRC were 94.7% and 72.5%. Sensitivity and specificity of Hb/Hp complex for adenomas sized ≥ 1 cm were 80% and 52.9% and for CRC were 100% and 52.9%. Sensitivity of FC and MMP-9 for CRC was 77.8% and 72.2%. Combined use of M2PK, iFOBT, and FC resulted in a sensitivity and specificity of 95% and 47.5% for the detection of adenomas sized ≥ 1 cm. Discussion. In CRC, sensitivity of M2PK, iFOBT, and Hb/Hp complex proved to be high. Combined use of M2PK, iFOBT, and FC may be valuable in the detection of large adenomas.

Prospective Comparison of Magnetic Resonance Imaging, Transrectal and Transperineal Sonography, and Surgical Findings in Complicated Perianal Crohn Disease.

OBJECTIVES: Magnetic resonance imaging (MRI) and transrectal sonography are the two accepted imaging modalities for evaluation of perianal fistulas and abscesses. Transperineal sonography is a new technique that is easy to learn and can be performed at any time. The purpose of this study was to prospectively compare the diagnostic accuracy of MRI, transrectal sonography, and transperineal sonography with surgical findings in patients with perianal Crohn disease. METHODS: All patients with perianal Crohn disease underwent MRI, transrectal sonography, and transperineal sonography within a few days before surgery. Fistulas were classified as simple (43.8%) or complex (52.2%) based on surgical findings. RESULTS: Twenty-three patients with active perianal Crohn disease (12 women and 11 men; mean age, 29.9 years; current therapy: antibiotics, 69.6%; azathioprine, 56.5%; and biologics, 73.9%; previous surgery, 26.1%; and proportion of smokers, 39.1%) were included. Sensitivity values for MRI, transrectal sonography, and transperineal sonography for diagnosis of fistulas were 84.6%, 84.6%, and 100%, respectively. Transperineal sonography was more sensitive for diagnosis of perianal abscesses than MRI and transrectal sonography (100%, 58.8%, and 92.8%). CONCLUSIONS: Transperineal sonography is a very accurate diagnostic method with outstanding sensitivity compared with MRI and transrectal sonography for evaluation of complicated perianal Crohn disease. Due to its simplicity and low cost, it is recommended that transperineal sonography be the first diagnostic modality in these cases.

[Neoadjuvant treatment as a limiting factor to rectal ultrasonography]. / A neoadjuváns kezelés mint a rectalis ultrahangvizsgálat korlátozó tényezoje.

INTRODUCTION: Rectal ultrasonography is a basic method for staging rectal cancer. Tissue changes after neoadjuvant treatment alter the accuracy of the method. AIM: The aim of the authors was to assess the accuracy of rectal ultrasonography after preoperative chemo-radiotherapy compared to the initial staging accuracy. METHOD: Rectal ultrasounds performed between 2006 and 2014 were assessed retrospectively. Ultrasonographic and pathological T and N stages were compared both in case of initial staging (control group) and re-staging. RESULTS: T staging was accurate in 70% in the control group and in 61% in re-staging. Rate of overstaging was 31% after neoadjuvant treatment. None of the ypT0 cases were identified. N staging accuracy was 64% in the control group and 61% in re-staging. CONCLUSIONS: Neoadjuvant treatment impairs the accuracy of rectal ultrasound. The role of re-staging with rectal ultrasonography is debatable in the assessment of the efficacy of oncological treatment and surgical planning. Orv. Hetil., 2016, 157(30), 1193-1197.

[Cost-effectiveness trial of self-expandable metal stents and plastic biliary stents in malignant biliary obstruction]. / A fém- és muanyag stentek költséghatékonysága malignus epeúti szukületek esetében - összehasonlító vizsgálat.

INTRODUCTION: Self-expandable metal and plastic stents can be applied in the palliative endoscopic treatment of patients with unresectable malignant biliary obstruction. The use of metal stentsis recommended if the patient's life expectancy is more than four months. AIM: To compare the therapeutic efficacy and cost-effectiveness of metal and plastic stents in the treatment of malignant biliary obstruction. METHOD: The authors retrospectively enrolled patients who received metal (37 patients) or plastic stent (37 patients). The complication rate, stent patency and cumulative cost of treatment were assessed in the two groups. RESULTS: The complication rate of metal stents was lower (37.84% vs. 56.76%), but the stent patency was higher compared with plastic stents (19.11 vs. 8.29 weeks; p = 0.0041). In the plastic stent group the frequency of hospitalization of patients in context with stent complications (1.18 vs. 2.32; p = 0.05) and the necessity of reintervention for stent dysfunction (17 vs. 27; p = 0.033) were substantially higher. In this group multiple stent implantation raised the stent patency from 7.68 to 10.75 weeks. There was no difference in the total cost of treatment of malignant biliary obstruction between the two groups (p = 0.848). CONCLUSIONS: Considering the cost of treatment and the burden of patients the authors recommend self-expandable metal sten timplantation if the life expectancy of patients is more than two months. In short survival cases multiple plastic stent implantation is recommended.

[Long-term adalimumab therapy in ulcerative colitis in clinical practice: result of the Hungarian multicenter prospective study]. / Az adalimumab hatékonysága és biztonságossága hagyományos kezelésre refrakter colitis ulcerosában.

INTRODUCTION: Adalimumab was approved for the treatment of ulcerative colitis refractory to conventional therapy several years later than infliximab in Europe. Due to the relatively low remission rate observed in Ultra trials, data on the efficacy of adalimumab in ulcerative colitis are really helpful in the daily practice. AIM: The aim of this study was to prospectively collect data on induction and maintenance adalimumab therapy in patients with ulcerative colitis treated in Hungarian centres. METHOD: This prospective study collected data of all patients with ulcerative colitis treated with adalimumab in 10 Hungarian centres. The primary endpoints of the study were rates of remission, response and primary failure at week 12, and the rate of continuous clinical response, remission and loss of response at weeks 30, and 52. Secondary endpoints were endoscopic outcome at week 52 and comparison of the efficacy of adalimumab between treatment naive and infliximab-experienced patients. RESULTS: 73 patients with active ulcerative colitis were enrolled in the study. 75.3% of the patients exhibited clinical response after the induction at week 12. The probability of maintaining adalimumab treatment was 48.6% at week 52 with a continuous clinical response in 92% of these patients. Mucosal healing was achieved in 48.1% of the patients at week 52. Dose intensification was performed in 17.6% of the patients. Minor side effects developed in 4% of the patients and 5.4% of the patients underwent colectomy during the 1-year treatment period. CONCLUSIONS: These results coming from the real clinical setting demonstrate a favourable efficacy of adalimumab induction and maintenance therapy in patients with ulcerative colitis.

Is mucosal healing more common than clinical remission in ulcerative colitis? - Is it the truth or only a myth coming from the studies?

BACKGROUND: The most important goals of the recent therapies of ulcerative colitis (UC) are to induce and maintain clinical remission and to achieve mucosal healing (MH). Rate of endoscopic remission has been shown to be higher than that of clinical remission in large trials like ULTRA and PURSUIT. The aim of our study was to evaluate the correlation between clinical and endoscopic disease activities of UC defined by activity scores. METHODS: Clinical and endoscopic activities were evaluated in 100 consecutive UC patients. Clinical activities were defined by two activity indices: the Rachmilewitz Activity Index (CAI) and the partial Mayo score. Colonoscopies and patient enrollments were performed by two experienced gastroenterologists and endoscopists. They graded the findings both according to the endoscopic part of the Rachmilewitz Endoscopic Activity Index (EI) and the Mayo endoscopic subscore. MH was defined as Mayo endoscopic subscore and EI of 0. Histological activity was scored by Riley score. RESULTS: Clinical and endoscopic activities showed strong correlations using both scoring systems (p = 0.0029 and p = 0.0001). Endoscopic disease activity also correlated with the histological activity (p ≥ 0.001). Significant correlation was shown between the clinical activity and MH (p = 0.0012 and p ≥ 0.001). No association was showed with the extension of the disease and clinical or endoscopic activity. CONCLUSION: Assessment of MH is very important for guiding therapy and for evaluation of remission in patients with UC. Our result showed good correlation between the clinical, endoscopic, and histological activities of UC focusing on the importance of evaluating the endoscopic activity of the patients.

[Comparison of symptoms, laboratory parameters and illness perception in patients with irritable bowel syndrome and inflammatory bowel disease]. / Tünetek, laboratóriumi paraméterek és a betegségpercepció eltérései irritábilis bél szindróma és gyulladásos bélbetegség esetén. Segíthetnek-e a kérdoívek a két betegség elkülönítésében?

INTRODUCTION: Symptoms-based differential diagnosis of irritable bowel syndrome and inflammatory bowel disease is often difficult. AIMS: To determine the differential diagnostic ability of clinical activity indexes and psychological questionnaires in these conditions, which have never been simultaneously analyzed. METHOD: 37 irritable bowel syndrome, 54 Crohn's disease and 41 ulcerative colitis patients were enrolled in the study. The patients completed the Crohn's Disease Activity Index test, Illness Perception Questionnaire and Inflammatory Bowel Disease Questionnaire. Hematocrit and C-reactive protein level of patients were also analyzed. RESULTS: Patients with irritable bowel syndrome felt their abdominal pain more severe than the other two groups (p = 0.005), while the quality of life was the worst in Crohn's disease (p = 0.0000001). Significantly more patients with inflammatory bowel disease considered that their condition is lifelong (p = 0.000781). The knowledge about disease was more appropriate in patients with inflammatory bowel disease (p = 0.00629). No significant difference was found in hematocrit levels, but the C-reactive protein level was significantly lower in patients with irritable bowel syndrome (p = 0.001). CONCLUSIONS: Illness perception questionnaires and C-reactive protein can help in the differentiation of inflammatory bowel disease from irritable bowel syndrome.

Accuracy of the Pancolonic Modified Mayo Score in predicting the long-term outcomes of ulcerative colitis: a promising scoring system.

Background: Different endoscopic scoring systems for assessing ulcerative colitis (UC) severity are available. However, most of them are not correlated with disease extent. Objectives: Our study aimed to compare the predictive value of the PanMay score versus the endoscopic Mayo (MES), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Dublin score in predicting long-term outcomes of UC. Design: This retrospective study enrolled consecutive UC patients who underwent colonoscopy before at least a 3-year follow-up. Methods: The PanMayo, MES, UCEIS, and Dublin scores and the baseline clinical and demographic characteristics of the participants were assessed. Endpoints were disease flare that required novel biological therapy, colectomy, and hospitalization. Patients were stratified using baseline clinical activity. Results: Approximately 62.8% of the 250 enrolled patients were in clinical remission. In these patients, the PanMayo, MES, and Dublin scores were positively associated with the risk of clinical flare. The MES score increased with clinical flare. The PanMayo score (>12 points), but not the MES score, was associated with the need for novel biological initiation and biological escalation. Furthermore, the Dublin and UCEIS scores of patients in remission who need novel biological treatment had a similar trend. Colectomy risk was associated with PanMayo and Dublin scores. Conclusion: The combined endoscopic assessment of disease extent and severity can be more accurate in predicting outcomes among patients with UC.
