RESUMEN
Crohn's disease (CD) is a chronic, fluctuating inflammatory condition that primarily affects the gastrointestinal tract. Although the incidence of CD in Taiwan is lower than that in Western countries, the severity of CD presentation appears to be similar between Asia and the West. This observation indicates the urgency for devising revised guidelines tailored to the unique reimbursement system, and patient requirements in Taiwan. The core objectives of these updated guidelines include the updated treatment choices and the integration of the treat-to-target strategy into CD management, promoting the achievement of deep remission to mitigate complications and enhance the overall quality of life. Given the diversity in disease prevalence, severity, insurance policies, and access to medical treatments in Taiwan, a customized approach is imperative for formulating these guidelines. Such tailored strategies ensure that international standards are not only adapted but also optimized to local contexts. Since the inception of its initial guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease (TSIBD) has acknowledged the importance of continuous revisions for incorporating new therapeutic options and evolving disease management practices. The latest update leverages international standards and recent research findings focused on practical implementation within the Taiwanese healthcare system.
RESUMEN
Ulcerative colitis (UC) is a chronic inflammation of the gastrointestinal tract and is characterized by alternating periods of inflammation and remission. Although UC incidence is lower in Taiwan than in Western countries, its impact remains considerable, demanding updated guidelines for addressing local healthcare challenges and patient needs. The revised guidelines employ international standards and recent research, emphasizing practical implementation within the Taiwanese healthcare system. Since the inception of the guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease has acknowledged the need for ongoing revisions to incorporate emerging therapeutic options and evolving disease management practices. This updated guideline aims to align UC management with local contexts, ensuring comprehensive and context-specific recommendations, thereby raising the standard of care for UC patients in Taiwan. By adapting and optimizing international protocols for local relevance, these efforts seek to enhance health outcomes for patients with UC.
RESUMEN
BACKGROUND/PURPOSE: Limited studies have addressed the exacerbation of symptoms and long COVID in inflammatory bowel disease (IBD) patients following non-severe COVID-19 infection, particularly with post-COVID-19 vaccination. We aim to investigate factors associated with exacerbated gastrointestinal symptoms (EGS) and long COVID in IBD patients with non-severe COVID-19, which is most common situation in daily practice. METHODS: This is an observational study by multiple centers in Taiwan from May 2020 to March 2023. We collected clinical manifestation, data, and medication information from IBD patients with non-severe COVID-19. EGS was defined as increased frequency of diarrhea, bloody stool, and abdomen pain within 14 days after SARS-COV-2 infection. Long COVID was defined following the guidelines of the World Health Organization. RESULTS: Out of 90 patients, most of them (88.9%) received at least standard two doses of COVID-19 vaccination and the majority (87.8%) were mild diseases of COVID-19.30% of patients experienced EGS during COVID-19 with higher ESR levels serving as a predictive factor (Odds ratio: 3.6, 95% confidence interval: 1.2-10.5, P = 0.02). 38.1% of those patients developed long COVID. The patients who experienced EGS during COVID-19 and with a history of longer IBD duration showed a significant association with long COVID (p = 0.03 and p = 0.02). CONCLUSION: Our study revealed that EGS and long COVID occurred in one third of IBD patients with non-severe COVID-19, even though most of them had received the standard plus booster vaccination. We identified associated factors for EGS and long COVID, emphasizing the importance of post-COVID-19 follow-up in IBD patients.

BACKGROUND: /Purpose: Leukocyte esterase strips have been widely used to detect the presence of leukocyte in human body fluids. We investigated the correlation between fecal leukocyte esterase (FLE) and fecal calprotectin (FC) levels and compared manual with machine automated interpretation of FLE level. METHODS: This prospective study enrolled inflammatory bowel disease and colitis patients in National Taiwan University Hospital from Dec 2021 to Feb 2022. FLE and FC measured using the same sample were compared with various FC cutoff values. The correlation between values indicated by the two tests was analyzed. Sensitivity, specificity, positive and negative predictive values, and area under the receiver operating characteristic curve (AUROC) were calculated using SAS. RESULTS: A total of 103 samples were analyzed. The correlation between FLE and FC level was moderate and positive (r = 0.3505, P = 0.0003). With an FLE reading more than 1+ indicating mucosa inflammation, when the FC cutoff was 50, 250, and 500 mg/kg, the sensitivities of FLE readings were 60.3 %, 74.3 %, and 84.6 %, respectively, and the specificities were 62.9 %, 58.8 %, and 58.4 %, respectively. With an FLE reading greater than 1+ indicating mucosa inflammation, FLE reflected FC with AUROC values at the optimal cutoff (500 mg/kg) of 0.72. No difference was noted between manual and machine readings for FLE. CONCLUSION: Positive FLE can predict FC levels of more than 500 mg/kg. The test is widely available, produces results on the same day, and is low cost; therefore, FLE should be further investigated for use in bowel inflammation monitoring.
RESUMEN
Background: Population-based data on the course of perianal disease in East Asian populations with Crohn's disease (CD) are limited. This study examined the prevalence, clinical course, and compared the outcomes of CD patients with perianal CD (pCD) versus without pCD in Taiwan. Methods: A nationwide population-based study was implemented from 2000 to 2017 by using the Taiwan National Health Insurance Research Database. Results: Of 2424 patients with CD, 358 (14.8%) patients with pCD were identified. Most patients with CD and pCD were men (79.3%). The mean age at CD diagnosis was lower in patients with pCD (33.7 years) than in those without pCD (44.9 years). Approximately half the patients with pCD received the pCD diagnosis at least 6 months before receiving a CD diagnosis. Approximately one-third (121/358) of patients with pCD had recurrent fistula; the median recurrence interval was 239 days. Compared with patients without pCD, patients with pCD had higher mean incidences of hospitalization (7.0 vs 3.8, Pâ <â .01), outpatient visits (13 vs 2.9, Pâ <â .01), and emergency room visits (10.3 vs 4.4, Pâ <â .01) over a 15-year period. Although patients with pCD had higher rates of healthcare utilization, their 15-year mortality rate was lower than that of those without pCD (6.1% vs 17.3%, Pâ <â .01). Conclusions: The period prevalence of pCD in Taiwanese patients with CD was 14.8%. Although patients with pCD required more intensive care and had greater healthcare utilization, they did not have inferior survival outcomes compared with those without pCD.
RESUMEN
BACKGROUND/AIMS: Long-term immunosuppressive therapies used to treat inflammatory bowel disease (IBD) are associated with an increased risk of infections, many of which can be prevented by vaccination. We assessed physicians' current approaches and clinical practices regarding vaccinations for IBD patients in different Asian countries/regions. METHODS: An internet-based survey was conducted among members of the Asian Organization for Crohn's and Colitis from September 2020 to November 2020. The questionnaire consisted of 2 parts covering general opinion on the relevance of vaccinations and clinical practice of vaccination. RESULTS: Overall, 384 Asian medical doctors responded to the survey. The majority of respondents considered it very (57.6%) or sufficiently (39.6%) important to perform vaccinations as recommended by the guidelines. About half of the Asian physicians (52.6%) were usually or always performing vaccinations. The influenza vaccine was the most frequently recommended vaccine for IBD patients. Half of the respondents (51.3%) did not recommend hepatitis A vaccine, especially in China (61.6%) and Japan (93.6%). The diphtheria, tetanus, and pertussis vaccine were never (35.2%) or rarely (29.4%) recommended. CONCLUSIONS: The findings of this survey indicated similarities among countries/regions in terms of the current approaches and practices regarding vaccination of IBD patients; however, there are some differences that might reflect each country's domestic vaccination guidelines and health insurance particularly with certain vaccines in some countries/regions. Although Asian physicians largely recommend vaccination, more awareness among doctors and Asian consensus regarding differences in IBD vaccination among countries/regions may be required.
RESUMEN
PURPOSE: The most widely used score for assessing the activity of Crohn's disease (CD) is the Magnetic Resonance Index of Activity (MaRIA) score, but it is time-consuming. The aim of this study was to compare the diagnostic accuracy of MaRIA score to the other two easily calculated scores. METHODS: Between January 2011 and May 2021, 67 patients with CD who underwent MRE and ileocolonoscopy within 2 weeks were enrolled. The MRE-based scores including the MaRIA score, simplified MaRIA (sMaRIA) score, and Nancy score for each colonic segment and terminal ileum were calculated and correlated with the ileocolonoscopic findings. The simplified endoscopic score for Crohn's disease (SES-CD) was considered the gold standard. RESULTS: A total of 343 intestinal segments were included in the analysis, of which 109 (31.8%) showed active inflammation on ileocolonoscopy. The areas under the receiver operating characteristic curve (AUC) of the MaRIA, sMaRIA, and Nancy scores for detecting active disease were 0.752, 0.764, and 0.765, respectively. In the sub-analysis for different indications, the MaRIA and sMaRIA scores showed a higher AUC (0.721 and 0.741) than the Nancy score (0.652) for disease monitoring. CONCLUSION: The sMARIA and Nancy scores showed comparable diagnostic accuracy to the MaRIA score, and thus could be used as alternatives to the MaRIA score. Furthermore, considering the range of application, especially for disease monitoring, the sMaRIA score may be more suitable for use in clinical practice.

BACKGROUND: There is a rapid increase in the incidence of inflammatory bowel diseases (IBD) in newly industrialized countries, yet epidemiological data is incomplete. We herein report the methodology adopted to study the incidence of IBD in newly industrialized countries and to evaluate the effect of environmental factors including diet on IBD development. METHODS: Global IBD Visualization of Epidemiology Studies in the 21st Century (GIVES-21) is a population-based cohort of newly diagnosed persons with Crohn's disease and ulcerative colitis in Asia, Africa, and Latin America to be followed prospectively for 12 months. New cases were ascertained from multiple sources and were entered into a secured online system. Cases were confirmed using standard diagnostic criteria. In addition, endoscopy, pathology and pharmacy records from each local site were searched to ensure completeness of case capture. Validated environmental and dietary questionnaires were used to determine exposure in incident cases prior to diagnosis. RESULTS: Through November 2022, 106 hospitals from 24 regions (16 Asia; 6 Latin America; 2 Africa) have joined the GIVES-21 Consortium. To date, over 290 incident cases have been reported. All patients have demographic data, clinical disease characteristics, and disease course data including healthcare utilization, medication history and environmental and dietary exposures data collected. We have established a comprehensive platform and infrastructure required to examine disease incidence, risk factors and disease course of IBD in the real-world setting. CONCLUSIONS: The GIVES-21 consortium offers a unique opportunity to investigate the epidemiology of IBD and explores new clinical research questions on the association between environmental and dietary factors and IBD development in newly industrialized countries.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic had a great impact on healthcare system and patients. This study aimed to evaluate the effect of the COVID-19 pandemic on the perceptions of patients with inflammatory bowel disease (IBD). METHODS: This prospective multicenter study was conducted between July 2021 and December 2021. Patients with IBD answered a structured questionnaire, and their degree of anxiety was assessed using a visual analogue scale (VAS) before and after reading educational materials. RESULTS: A total of 225 (47.67%) patients with Crohn's disease, 244 (51.69%) with ulcerative colitis and 3 (0.64%) with indeterminate colitis were enrolled. Common concerns were adverse events from vaccination (20.34%), and higher risks of developing severe COVID-19 (19.28%) and COVID-19 infection (16.31%) than the general population. Medications deemed by the patients to increase the risk of COVID-19 were immunomodulators (16.10%), anti-tumor necrosis factor-α antagonists (9.96%), and corticosteroids (9.32%). Thirty-five (7.42%) patients self-discontinued IBD medication, of whom 12 (34.28%) had worse symptoms. Older age (>50 years) (OR 1.10, 95% CI 1.01-1.19, p = 0.03), IBD-related complications (OR 1.16, 95% CI 1.04-1.28, p = 0.01), education status below senior high school (OR 1.22, 95% CI 1.08-1.37, p = 0.001), and residing in north-central Taiwan (OR 1.21, 95% CI 1.10-1.34, p < 0.001) were associated with more anxiety. None of the enrolled patients contracted COVID-19. The anxiety VAS score (mean ± SD) improved after reading the educational materials (3.84 ± 2.33 vs. 2.81 ± 1.96, p < 0.001). CONCLUSION: The medical behavior of IBD patients was influenced by the COVID-19 pandemic, and their anxiety could be mitigated after education.

Crohn's disease (CD) is a chronic inflammatory disease mainly affecting the gastrointestinal tract. With the increased availability of modalities in the last two decades, the treatment of CD has advanced remarkably. Although medical treatment is the mainstay of therapy, most patients require surgery during the course of their illness, especially those who experience complications. Nutritional optimization and ERAS implementation are crucial for patients with CD who require surgical intervention to reduce postoperative complications. The increased surgical risk was found to be associated with the use of corticosteroids, but the association of surgical risk with immunomodulators, biologic therapy, such as anti-TNF mediations, anti-integrin medications, and anti-IL 12/23 was low in certainty. Decisions about preoperative medication must be made on an individual case-dependent basis. Preoperative imaging studies can assist in the planning of appropriate surgical strategies and approaches. However, patients must be informed of any alterations to their treatment. In summary, the management of perioperative medications and surgery-related decision-making should be individualized and patient-centered based on a multidisciplinary approach.
RESUMEN
BACKGROUND: This nationwide prospective registry study investigated the real-world effectiveness, safety, and persistence of vedolizumab (VDZ) in inflammatory bowel disease (IBD) patients in Taiwan. Disease relapse rates after VDZ discontinuation due to reimbursement restriction were assessed. METHODS: Data were collected prospectively (January 2018 to May 2020) from the Taiwan Society of IBD registry. RESULTS: Overall, 274 patients (147 ulcerative colitis [UC] patients, 127 Crohn's disease [CD] patients) were included. Among them, 70.7% with UC and 50.4% with CD were biologic-naïve. At 1 year, 76.0%, 58.0%, 35.0%, and 62.2% of UC patients and 57.1%, 71.4%, 33.3%, and 30.0% of CD patients achieved clinical response, clinical remission, steroid-free remission, and mucosal healing, respectively. All patients underwent hepatitis B and tuberculosis screening before initiating biologics, and prophylaxis was recommended when necessary. One hepatitis B carrier, without antiviral prophylaxis due to economic barriers, had hepatitis B reactivation during steroid tapering and increasing azathioprine dosage, which was controlled with an antiviral agent. No tuberculosis reactivation was noted. At 12 months, non-reimbursement-related treatment persistence rates were 94.0% and 82.5% in UC and CD patients, respectively. Moreover, 75.3% of IBD patients discontinued VDZ due to mandatory drug holiday. Relapse rates after VDZ discontinuation at 6 and 12 months were 36.7% and 64.3% in CD patients and 42.9% and 52.4% in UC patients, respectively. CONCLUSIONS: The findings demonstrated VDZ effectiveness in IBD patients in Taiwan, with high treatment persistence rates and favorable safety profiles. A substantial IBD relapse rate was observed in patients who had mandatory drug holiday.

BACKGROUND: Purpose: Anemia affects the life quality of inflammatory bowel disease (IBD) patients, but no report from Asian about anemia screening and its impact previously. We aimed to explore the prevalence and impact of anemia among the IBD patients in Taiwan. METHODS: A retrospective study was conducted from January 2006 to February 2018 at National Taiwan University Hospital. Clinical characteristics and outcomes were analyzed. RESULTS: A total of 1604 IBD patients were enrolled [494 Crohn's disease (CD) and 1110 ulcerative colitis (UC)]. Overall, 95.3% (471/494) of CD and 87.9% (976/1110) of UC patients underwent anemia screening. Anemia screening rate in IBD patients significantly increased from 62.6% (162/259) in 2006 to 77.2% (838/1086) in 2017. The mean time from IBD diagnosis to anemia screening was 122.4 days in CD patients and even longer in UC patients at 216.2 days. Persistent anemia was found in 47.3% (548/1158) of the screened patients. Risk factors of persistent anemia included low body mass index [odds ratio (OR) = 1.96, p < 0.01], steroid [OR = 2.96, p < 0.01], thiopurine [OR = 2.62, p < 0.01], colectomy [OR = 6.3, p < 0.01], and small bowel resection [OR = 3.21, p < 0.05)] after IBD diagnosis. Compared with those without anemia, anemic IBD patients had higher admission (p < 0.01) and mortality rates (p < 0.01). CONCLUSION: The anemia screening rate was acceptable and increased over time in Taiwan. Since anemia is associated with worse outcomes, earlier survey and treatment of anemia in IBD patients is recommended.

BACKGROUND & AIMS: The evolving epidemiologic patterns of inflammatory bowel disease (IBD) throughout the world, in conjunction with advances in therapeutic treatments, may influence hospitalization rates of IBD. We performed a systematic review with temporal analysis of hospitalization rates for IBD across the world in the 21st century. METHODS: We systematically reviewed Medline and Embase for population-based studies reporting hospitalization rates for IBD, Crohn's disease (CD), or ulcerative colitis (UC) in the 21st century. Log-linear models were used to calculate the average annual percentage change (AAPC) with associated 95% confidence intervals (95% CIs). Random-effects meta-analysis pooled country-level AAPCs. Data were stratified by the epidemiologic stage of a region: compounding prevalence (stage 3) in North America, Western Europe, and Oceania vs acceleration of incidence (stage 2) in Asia, Eastern Europe, and Latin America vs emergence (stage 1) in developing countries. RESULTS: Hospitalization rates for a primary diagnosis of IBD were stable in countries in stage 3 (AAPC, -0.13%; 95% CI, -0.72 to 0.97), CD (AAPC, 0.20%; 95% CI, -1.78 to 2.17), and UC (AAPC, 0.02%; 95% CI, -0.91 to 0.94). In contrast, hospitalization rates for a primary diagnosis were increasing in countries in stage 2 for IBD (AAPC, 4.44%; 95% CI, 2.75 to 6.14), CD (AAPC, 8.34%; 95% CI, 4.38 to 12.29), and UC (AAPC, 3.90; 95% CI, 1.29 to 6.52). No population-based studies were available for developing regions in stage 1 (emergence). CONCLUSIONS: Hospitalization rates for IBD are stabilizing in countries in stage 3, whereas newly industrialized countries in stage 2 have rapidly increasing hospitalization rates, contributing to an increasing burden on global health care systems.

BACKGROUND & AIMS: Despite the lack of evidence for the benefits of dietary restrictions for ulcerative colitis (UC), the majority of patients with UC restrict their diets to avoid relapses. Few studies have examined information resources that affect patients' dietary beliefs or practices, but none have investigated UC patients in clinical remission from Asia. This survey investigated the dietary beliefs, practices, and information resources of Taiwanese UC patients in clinical remission. METHODS: A self-reported questionnaire was administered. Fifty UC patients in clinical remission (defined based on having a 2-item patient-reported outcome score of ≤1 with no rectal bleeding for ≥90 days) were recruited from National Taiwan University Hospital between September 2017 and March 2018. RESULTS: In total, 22 patients (45.8%) believed diet to be the initiating factor for UC, and 48.0% of patients believed diet has ever triggered relapses. Forty-two patients (85.7%) avoided specific foods to prevent a relapse. Spicy foods were the most avoided foods (75.5%), following by alcohol (69.4%), carbonated beverages (63.3%), milk or milk products (59.2%), and fatty foods (59.2%). The patients' information resources for dietary beliefs and practices consisted mainly of their own experience. Approximately one-third of the patients have avoided the same menu with their family or avoided outdoor dining to prevent UC relapses. CONCLUSIONS: This is the first dietary belief survey focusing on clinical remission UC patients from Asia. Most clinical remission UC patients spontaneously avoided specific foods based on their own experiences. Dietary restrictions may negatively affect patients' social lives. Further dietary counseling is necessary to minimize the possible negative impacts on UC patients in clinical remission.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a relative safe procedure in bariatric surgery. However, relatively few studies had been assessed its comprehensive efficacies. In the current study, the efficacies of LSG were comprehensively explored on glycemic control and cardiovascular disease (CVD) risk reduction. METHODS: A total of 95 obese patients, who owned body mass index (BMI) of more than 35, were recruited. All of them primarily underwent LSG from 2014 to 2016. Type 2 diabetes mellitus (T2DM) remission was defined as levels of glycated hemoglobin (A1C) and fasting blood glucose (FBG) of less than 6.4% and 125 mg/dL, respectively. The further efficacies of LSG on CVD and coronary heart disease (CHD) risks were explored by using original- and recalibrated Framingham 10-year CHD risk scores and the other 3 well-established CVD risk prediction models. RESULTS: Systolic blood pressure (SBP), serum FBG, A1C, triglyceride (TG), BMI, and body weight showed significantly declined and high-density lipoprotein-cholesterol (HDL) displayed twice higher than beginning level after LSG. The 71 of 95 patients with obesity were T2DM; 62 of them exhibited persistent DM remission until 1 year after LSG. Cardiovascular age, general cardiovascular risk (GCVR), and atherosclerotic cardiovascular disease risk (ASCVD) also showed significant decrements after LSG. We also observed significant reductions in estimated CVD and CHD risks. CONCLUSION: LSG resulted in a persistent T2DM remission and corrected metabolic abnormalities. Subsequently, LSG also benefits declined risks of CVD and 10-year CHD developments. LSG may be helpful for primary CVD care in obese patients with BMI of more than 35.

Smoking influences the risks of inflammatory bowel disease (IBD). A hospital-based cohort was conducted to evaluate the effect of smoking on the development and outcomes of IBD, with age, sex and comorbidities matched non-IBD controls from the National Health Interview Survey database of Taiwan. 700 IBD patients (360 ulcerative colitis (UC), 340 Crohn's disease (CD)) were analyzed for outcomes; and 575 patients (297 UC, 278 CD) were analyzed for prevalence. Smoking prevalence was significantly lower in UC patients than controls (20.9% vs. 30.4%, p < 0.01), but no difference between CD patients and controls (19.8% vs. 22.1%, p = 0.60). UC smokers had fewer admissions (1.6 vs. 2.5, p < 0.05) but higher rates of new cancer development (16% vs. 6.7%, p < 0.05) and mortality (16% vs. 4.9%, p < 0.01) than nonsmokers. CD smokers tended to have higher rates of stricturing and penetrating diseases (p < 0.05), and higher surgery risk (60.3% vs. 38.3%, p < 0.01) than nonsmokers. Smoking prevents UC occurrence and is associated with fewer hospitalization but increases risks of cancer and mortality. By contrast, smoking does not affect CD occurrence but is related to more aggressive behavior which results in a higher surgical rate.

BACKGROUND: Primary signet ring cell carcinoma of the colon and rectum (PSRCCR) is rare, usually diagnosed at advanced stage with poor outcomes. We aimed to find possible diagnostic clues in order to help diagnosis. METHODS: A retrospective study of PSRCCR patients from 1993 to 2018 was reviewed at a single tertiary center. Colorectal adenocarcinoma patients as control group with 1:4 ratio was also enrolled. RESULTS: 18 patients with PSRCCR were identified. The prevalence rate was 0.16% (18 of 11,515). The mean age was 50.2 years-old in PSRCCR group and 63 years-old in non-SRCC colorectal cancer patients (p < 0.001). Diagnosis tool depends on colonoscopy were much less in PSRCCR group than control group (44.4% vs 93%, p < 0.001). SRCC patients had higher level of CEA (68.3 vs 17.7 ng/mL, p = 0.004) and lower level of Albumin (3.4 vs 4.3 g/dL, p < 0.001). The majority of PSRCCR tumor configuration was ulcerative and infiltrative. More PSRCCR pathology presented as high-grade carcinoma (66.7 vs 1.4%, p < 0.001) and lymphovascular invasion (77.8 vs 44.4%, p = 0.011) than control group. More PSRCCR patients were diagnosed at advanced stage (88.8 vs 40.3%, p = 0.001). Higher mortality was also noticed in PSRCCR group than control group (72.2 vs 20.8%, p < 0.001). CONCLUSION: For young patients with long segment colonic stenosis and ulcerative/ infiltrative mucosa but endoscopic biopsy failed to identify malignant cells, earlier operation or non-colon site biopsy is suggested for diagnosing the PSRCCR.

BACKGROUND/AIMS: Primary sclerosing cholangitis (PSC) is associated with inflammatory bowel disease (IBD). We aimed to evaluate the prevalence, clinical manifestation, and outcomes of PSC in Taiwanese patients with IBD. METHODS: This retrospective study enrolled patients with IBD admitted from January 1, 1996, to December 31, 2018, to National Taiwan University Hospital. A case-matched analysis was performed comparing patients with IBD with and without PSC according to age, sex, and time of admission, with ratios of 1:4 and 1:2 in the adult and pediatric groups, respectively. RESULTS: In total, 763 patients with IBD were enrolled, 12 of whom were also diagnosed with PSC (1.57%). All these patients had ulcerative colitis (UC). A greater incidence of IBD with PSC was observed in younger patients than in older patients. Male sex was a risk factor for PSC in pediatric patients with IBD (P=0.015); 75% of these patients were diagnosed with PSC along with or after the diagnosis of UC. There was no significant difference in colitis extent and severity between the groups; however, a higher proportion of rectal sparing was observed in patients with PSC (P=0.001). There was no significant difference in cancer development between the groups (P=0.679). CONCLUSIONS: A 1.57% prevalence of PSC was observed in Taiwanese patients with IBD. The majority of patients with IBD and PSC were men and were diagnosed at a younger age. Hence, routine evaluation of biliary enzymes and liver imaging is recommended in young male patients with IBD.
RESUMEN
Conducting polymers (CPs) are of great interests to researchers around the world in biomedical applications owing to their unique electrical and mechanical properties. Besides, they are easy to fabricate and have long-term stability. These features make CPs a powerful building block of modern biomaterials. Peptide functionalization has been a versatile tool for the development of CP-based biomaterials. With the aid of peptide modifications, the biocompatibility, target selectivity, and cellular interactions of CPs can be greatly improved. Reflecting these aspects, an increasing number of studies on peptide-integrated conducting polymers have been reported recently. In this review, various kinds of peptide immobilization strategies on CPs are introduced. Moreover, the aims of peptide modification are discussed in three aspects: enhancing the specific selectivity, avoiding nonspecific adhesion, and mimicking the environment of extracellular matrix. We highlighted recent studies in the applications of peptide-integrated CPs in electrochemical sensors, antifouling surfaces, and conductive biointerfaces. These studies have shown great potentials from the integration of peptide and CPs as a versatile platform for advanced biological and clinical applications in the near future.
