Beheshti Maal A, Shahrbaf MA, Sadri B, Hossein-Khannazer N, Mansournia MA, Vosough M. Prevalence of Hepatobiliary Manifestations in Inflammatory Bowel Disease: A GRADE Assessed Systematic Review and Meta-Analysis of more than 1.7 Million Patients. J Crohns Colitis 2024; 18:360-374. [PMID: 37695111 DOI: 10.1093/ecco-jcc/jjad157] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 08/21/2023] [Accepted: 09/08/2023] [Indexed: 09/12/2023]
Abstract
BACKGROUND AND AIMS Inflammatory bowel disease [IBD] comprises an immune-mediated group of chronic gastrointestinal disorders. Patients with IBD may experience extraintestinal manifestations, such as hepatobiliary complications. This meta-analysis aims to assess the prevalence of different hepatic manifestations in IBD patients. METHODS For this systematic review and meta-analysis, PubMed, Scopus, Web of Science, and Embase were searched until July 20, 2022, by specifying keywords for IBD, hepatic manifestations, and study type. Full texts of cohort studies in English that examined the prevalence of different hepatic manifestations were included in this study. The primary outcome was the overall prevalence of hepatic manifestations in IBD patients. For the statistical analysis, a proportion by random effect model meta-analysis was performed. The registration number for the protocol of this study in PROSPERO is CRD42022369595. RESULTS From the 4421 articles retrieved from the primary search, 118 met the inclusion criteria and were included in the final analysis. After a pooled analysis of 1 729 128 patients, the overall prevalence of hepatic manifestations was 3.49% (95% confidence interval [CI]: 3.31-3.68%; I2: 99.55%). The pooled prevalence of non-alcoholic fatty liver disease in 228 216 patients was 26.1% [95% CI: 22.1-30.2%; I2: 99.018%]. After pooled analysis of 9642 patients, the prevalence of primary sclerosing cholangitis was 1.67% [95% CI: 1.47-1.88%; I2: 99.10%]. The pooled prevalence of biliary stones was 4.1% [95% CI: 3.6-4.7%; I2: 97.43%]. Autoimmune hepatitis (0.51% [95% CI: 0.26-0.75%]; I2: 85.36%) and portal vein thrombosis (0.21% [95% CI: 0.08-0.33%]; I2: 97.95%) are considered as rare manifestations. CONCLUSION This study summarizes the prevalence and importance of different hepatic manifestations in IBD patients. These findings are crucial for the management of extraintestinal manifestations, especially hepatic manifestations, in IBD patients.

Abstract
Primary sclerosing cholangitis (PSC) was declared one of the biggest unmet needs in hepatology during International Liver Congress 2016 in Berlin. Since then, not much has changed unfortunately, largely due to the still elusive pathophysiology of the disease. One of the most striking features of PSC is its association with inflammatory bowel disease (IBD), with the majority of patients with PSC being diagnosed with extensive colitis. This review describes the epidemiology of IBD in PSC, its specific phenotype, complications and potential pathophysiological mechanisms connecting the two diseases. Whether PSC is merely an extra-intestinal manifestation of IBD or if PSC and IBD are two distinct diseases that happen to share a common susceptibility that leads to a dual phenotype is debated. Implications for the management of the two diseases together are also discussed. Overall, this review summarises the available data in PSC-IBD and discusses whether PSC and IBD are one or two disease(s).

Abstract
BACKGROUND & AIMS Although the association between inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC) is well recognized, uncertainties remain about the magnitude of this problem. We conducted a systematic review and meta-analysis assessing prevalence of PSC in IBD to investigate whether type of IBD, how presence of PSC was defined, sex, disease extent or location, time period, or geographic location influenced prevalence. METHODS Medline, Embase, and Embase Classic were searched (from inception to April 10, 2021) to identify observational studies recruiting ≥50 adult patients with IBD and reporting prevalence of PSC. Data were extracted, and pooled prevalence, odds ratios (ORs), and 95% confidence intervals (CIs) calculated. RESULTS Of 1204 citations, 64 studies were eligible, containing 776,700 patients. Overall, pooled prevalence of PSC in IBD was 2.16%; it was highest in South America and lowest in Southeast Asia. Pooled prevalences in patients with ulcerative colitis (UC), Crohn's disease (CD), and IBD-unclassified were 2.47%, 0.96%, and 5.01%, respectively. Pooled prevalence was significantly higher in UC versus CD (OR 1.69, 95% CI 1.24-2.29). In subgroup analyses according to method used to define presence of PSC, the highest prevalence was 2.88% in studies performing both liver biochemistry and endoscopic retrograde/magnetic resonance cholangiopancreatography and the lowest was 1.79% in studies using a clinical diagnosis. Prevalence was generally higher in men, patients with more extensive, compared with left-side, UC or ileocolonic or colonic, compared with ileal, CD. CONCLUSIONS Our findings provide the first pooled estimates of the burden of PSC in IBD, as well as potential risk factors, which may be important in establishing a prompt diagnosis and initiating appropriate surveillance for relevant gastrointestinal malignancies.

Abstract
BACKGROUND/AIMS Autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) are the 3 main autoimmune liver diseases (AILDs). The epidemiology of AILD in Turkey is not known. To determine the scientific status, we performed a scientometric analysis of AILD-related original articles that originated from Turkey. MATERIALS AND METHODS We searched the Web of Science database, the Science Citation Index Expanded (SCI-E), and the Social Sciences Citation Index (SSCI) by using the keywords "autoimmune hepatitis," "primary biliary cholangitis/primary biliary cirrhosis," and "primary sclerosing cholangitis" in conjunction with "Turkey." A scientometric analysis was done on the search results. RESULTS We identified 117 AILD-related papers that were published in Turkey from 1997 to 2019. Among these, 70 case reports, letters, and reviews and 2 original articles that were not cited in SCI-E/SSCI were excluded. The remaining 45 original articles were further analyzed. These studies were related to AIH (n=22), PBC (n=7), PSC (n=9), PBC-AIH overlap (n=5), and others (n=2). Four of the publications originated in pediatric settings; 9 of 45 papers were published from 1997 to 2008 and 36 papers were published from 2009 to 2019. Most papers (75%) were reported from 5 centers; 9 papers (20%) were published in journals with an impact factor of 3 or higher. CONCLUSION The overall number and quality of AILD-related papers in Turkey are unexpectedly low, although a number of papers have received considerable international recognition. More epidemiologic, prospective, and multicenter research projects are warranted to advance AILD knowledge and to produce high-quality research from Turkey.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive, hepatobiliary disease characterized by inflammation and fibrosis of the intra- and extra-hepatic bile ducts. Its natural history is one that generally progresses towards cirrhosis, liver failure, cholangiocarcinoma, and ultimately disease-related death, with a median liver transplantation-free survival time of approximately 15-20 years. However, despite its lethal nature, PSC remains a heterogenous disease with significant variability in outcomes amongst different regions of the world. There are also many regions where the outcomes of PSC have not been studied, limiting the overall understanding of this disease worldwide. In this review, we present the geoepidemiologic variations in outcomes of PSC, with a focus on survival pre- and post-liver transplantation as well as the concurrence of inflammatory bowel disease and hepatobiliary neoplasia.

Abstract
BACKGROUND & AIMS The prevalence of primary sclerosing cholangitis (PSC) among patients with inflammatory bowel disease (IBD) is unclear. Patients with IBD might be screened for PSC using magnetic resonance cholangiography (MRC). We aimed to estimate the frequency and distribution of MRC-detected lesions that indicate PSC in patients with IBD 20 years after their initial diagnosis and to identify clinical characteristics associated with these findings. METHODS We performed a follow-up analysis of a population-based cohort of 756 patients in South-Eastern Norway diagnosed with IBD from January 1, 1990 through December 31, 1993. Of these subjects, 470 attended a follow-up evaluation 20 years later in which they were offered routine clinical blood testing and ileocolonoscopy; 322 were screened by MRC (222 with ulcerative colitis and 100 with Crohn's disease). Two radiologists independently evaluated results from the MRC examinations. RESULTS In the MRC examination, 24 patients (7.5%) were found to have PSC-like lesions; only 7 of these patients (2.2%) were known to have PSC. One patient was initially missed and 1 had small-duct PSC, so the final prevalence of PSC was 8.1%. Extensive colitis, a high prevalence of colectomy, and chronic and continuous symptoms of IBD occurred in significantly more patients with suspected PSC than without PSC (P = .029, P = .002, and P = .012, respectively). Among patients with subclinical features of PSC, the MRC progression score for PSC increased when they were re-examined after a median 3.2 years (P = .046). CONCLUSIONS Using MRC analysis of patients with long-term IBD, we found the prevalence of PSC to be around 3-fold higher than that detected based on symptoms. Sixty-five percent of patients had subclinical PSC associated with progressive IBD, with no biochemical abnormalities and mild disease, based on radiology findings. PSC appears to progress in patients with subclinical disease, but long-term outcomes are not known.

Abstract
Primary sclerosing cholangitis (PSC) is well characterized in European populations. We aimed to characterize clinical characteristics and human leukocyte antigen (HLA) associations in a population of European American, Hispanic, and African American PSC patients listed for liver transplantation (LT). Population-stratified demographic, clinical, and HLA data from 6767 LT registrants of the United Network for Organ Sharing who had a diagnosis of PSC (4.7% of the registrants) were compared to data from registrants with other diagnoses. Compared to European Americans and Hispanics, African Americans were significantly younger (46.6 ± 13.7, 42.3 ± 15.9, and 39.7 ± 13.1 years, respectively; P = 0.002) and were listed with a higher Model for End-Stage Liver Disease score (15.2 ± 7.5, 14.9 ± 7.6, and 18.1 ± 9.3, respectively; P = 0.001); they were also less frequently noted to have inflammatory bowel disease in comparison with European Americans (71.4% versus 60.5%, P < 0.01). In multivariate analysis, African origin was a significant factor associated with listing for LT with PSC (odds ratio with respect to European Americans = 1.325, 95% confidence interval = 1.221-1.438). HLA associations in European Americans, Hispanics, and African Americans with PSC versus alcoholic liver disease were detected for HLA-B8, HLA-DR13, and protective HLA-DR4. However, HLA-DR3, which is in linkage disequilibrium with HLA-B8, showed associations only in European Americans and Hispanics. In conclusion, African Americans with PSC who are listed for LT differ clinically from European Americans and Hispanics. The association with HLA-B8 but not HLA-DR3 in African Americans should make possible the refinement of the HLA associations in PSC.

Abstract
OBJECTIVES Although it is known that extraintestinal manifestations (EIMs) commonly occur in pediatric inflammatory bowel disease (IBD), little research has examined rates of EIMs and their relation to other disease-related factors in this population. The purpose of this study was to determine the rates of EIMs in pediatric IBD and examine correlations with age, sex, diagnosis, disease severity, and distribution. PATIENTS AND METHODS Data were prospectively collected as part of the Pediatric IBD Collaborative Research Group Registry, an observational database enrolling newly diagnosed IBD patients <16 years old since 2002. Rates of EIM (occurring anytime during the period of enrollment) and the aforementioned variables (at baseline) were examined. Patients with indeterminate colitis were excluded from the analysis given the relatively small number of patients. RESULTS One thousand nine patients were enrolled (mean age 11.6 +/- 3.1 years, 57.5% boys, mean follow-up 26.2 +/- 18.2 months). Two hundred eighty-five (28.2%) patients experienced 1 or more EIMs. Eighty-seven percent of EIM occurred within the first year. Increased disease severity at baseline (mild vs moderate/severe) was associated with the occurrence of any EIM (P < 0.001), arthralgia (P = 0.024), aphthous stomatitis (P = 0.001), and erythema nodosum (P = 0.009) for both Crohn disease (CD) and ulcerative colitis (UC) during the period of follow-up. Statistically significant differences in the rates of EIMs between CD and UC were seen for aphthous stomatitis, erythema nodosum, and sclerosing cholangitis. CONCLUSIONS EIMs as defined in this study occur in approximately one quarter of pediatric patients with IBD. Disease type and disease severity were commonly associated with the occurrence of EIMs.

Abstract
The Asia-Pacific region has been marked as an area with a low incidence of inflammatory bowel disease (IBD), although confusion always existed as to whether this low incidence was a result of low diagnostic awareness, a high incidence of infective diarrhoea and its diagnostic overlap or a true low incidence. As epidemiological studies from this region are being made available it is clear that the incidence and prevalence rates of IBD in Asia-Pacific region are low compared with Europe and North America. They are however, increasing rapidly. There are substantial variations in the incidence and prevalence rates of IBD in various ethnic groups in Asia. The highest incidence rates are recorded from India, Japan and the Middle East and there exists a genetic predisposition of South Asians (Indians, Pakistanis and Bangladeshis) to ulcerative colitis (UC). It appears that certain racial groups are more prone than others to develop IBD. For instance, Indians in South-East Asia have higher rates than Chinese and Malays. While there is a host genetic predisposition, environmental factor(s) may be responsible for this difference. The clinical phenotypes and complication rates of Asian IBD resemble those of the Caucasian population in general, but some heterogeneity is observed in different regions of Asia. There is no evidence of a north-south or an east-west divide in the Asia-Pacific region. The available studies suggest an increasing incidence of UC in the Asia-Pacific region and hence it is an appropriate time to launch well-designed epidemiological studies so that etiopathogenetic factors can be identified. There is a male predominance in Crohn's disease in the Asian population. The NOD2/CARD15 gene is not associated with CD in the Japanese, Korean, Chinese and Indian population.

Abstract
BACKGROUND Extraintestinal manifestations (EIMs) in pediatric patients with inflammatory bowel disease (IBD) are poorly characterized. We examined the prevalence of EIMs at diagnosis, subsequent incidence, and risk factors for EIMs. METHODS Data for 1649 patients from the PediIBD Consortium Registry, diagnosed with IBD before 18 years of age (1007 [61%] with Crohn's disease, 471 [29%] with ulcerative colitis, and 171 [10%] with indeterminate colitis), were analyzed using logistic regression, Kaplan-Meier, log rank tests, and Cox models. RESULTS EIMs were reported prior to IBD diagnosis in 97 of 1649 patients (6%). Older children at diagnosis had higher rates compared with younger children, and arthritis (26%) and aphthous stomatitis (21%) were most common. Among the 1552 patients without EIM at diagnosis, 290 developed at least 1 EIM. Kaplan-Meier estimates of cumulative incidence were 9% at 1 year, 19% at 5 years, and 29% at 15 years after diagnosis. Incidence did not differ by IBD type (P = 0.20), age at diagnosis (P = 0.22), or race/ethnicity (P = 0.24). Arthritis (17%) and osteopenia/osteoporosis (15%) were the most common EIMs after IBD diagnosis. CONCLUSIONS In our large cohort of pediatric IBD patients, 6% had at least 1 EIM before diagnosis of IBD. At least 1 EIM will develop in 29% within 15 years of diagnosis. The incidence of EIMs both before and after diagnosis of IBD differs by type of EIM and may be slightly higher in girls, but is independent of the type of IBD, age at diagnosis, and race/ethnicity.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive, cholestatic liver disease characterized by inflammation and fibrotic obliteration of the hepatic biliary tree. It is commonly associated with inflammatory bowel disease (IBD). A number of complications can occur which require special consideration, the most important of which is the development of cholangiocellular carcinoma (CCC). Unfortunately, no medical therapy is currently available for the underlying liver disease. Liver transplantation is an effective, life-extending option for patients with advanced PSC. Geographical variations between East and West include a second peak for age with a lower association with IBD in a Japanese population and female predominance in a lone study from Turkey. The clinical and biochemical Mayo criteria may not be universally applicable, as different patients show variations regarding the initial presentation and natural course of the disease. Directing research towards explaining these geographical differences and understanding the pathogenesis of PSC is required in order to develop better therapies for this devastating disease.

Abstract
Crohn's disease is a condition of chronic inflammation potentially involving any location of the alimentary tract from mouth to anus but with a propensity for the distal small bowel and proximal large bowel. Frequent complications include stricture and fistula. Numerous extra-intestinal manifestations may also be present. The aetiology of Crohn's disease is incompletely understood, and therapy, although generally effective in alleviating the symptoms, is not curative. Due to the heterogeneity of the disease a major need for the therapeutic approach is the ability to define subgroups with distinct characteristics. However, with regard to the heterogeneity of demographic, anatomic and disease behaviour characteristics, distillation of the numerous possible phenotypes in simple categories is a formidable task. In the present review the focus will be on clinically relevant situations providing therapeutic algorithms according to international guidelines.

Abstract
BACKGROUND Chronic ulcerative colitis is a disease of unknown etiology. Its incidence is on the rise in various developing countries as has been reported in studies from South-East Asia and the Middle East. There seems to be significant differences in the pattern and the clinical course of this disease in our patient population. The aim of our study is to assess the incidence and the clinical course of the disease in Kuwait. METHODS This is a retrospective study of cases identified over a period of 14 years (1985-1999). Three hundred forty-six patients were identified to have chronic ulcerative colitis. Ninety patients were interviewed for this study. RESULTS Chronic ulcerative colitis is being identified with increasing frequency. Our local incidence was 2.8 per 100,000 persons per year. The disease was seen in both sexes with equal frequency. It peaks at the third decade of life, with no second peak observed in the sixth decade. The disease was of mild to moderate severity in 93% of the cases. The distribution of the disease in the colon showed pancolitis in 45%, left-sided colitis in 14%, proctosigmoiditis in 21% and proctitis in 20%. Arthritis and arthralgia were the most frequent extraintestinal manifestation seen in 31%. Perianal disease, although rare in ulcerative colitis, was seen in 8%. Of interest is the fact that over 14 years of follow-up, none of our patients developed high-grade dysplasia or colorectal cancer. Four patients required total colectomy mainly due to failure of medical therapy. CONCLUSIONS Chronic ulcerative colitis is occurring with increasing frequency similar to that seen in Western countries. The disease observed in our patient population was of mild to moderate severity, with fewer complications than reported in Western countries. It peaks in the third decade with no second peak. None of our patients developed high-grade dysplasia or colorectal carcinoma.

Abstract
Primary sclerosing cholangitis in children can mimic autoimmune hepatitis in the absence of inflammatory bowel disease. Most adult patients have been identified with human leukocyte antigens that either predispose or protect against disease. Novel class I alleles and cytokine polymorphisms may also contribute to disease susceptibility. Primary alpha-hemolytic streptococci infection does not appear to directly cause primary sclerosing cholangitis. Promising diagnostic modalities such as single photon emission tomography require further study in comparison with cholangiographic techniques. Positron-emission tomography and DNA cytometry appear promising for confirming occult cholangiocarcinoma when present. The chemoprevention effects of ursodeoxycholic acid on colorectal dysplasia await further investigation. Initial results from high-dose ursodeoxycholic acid in halting disease progression, however, suggest a beneficial effect. In contrast, the impact of endoscopic therapy on natural history remains unresolved. Although liver transplantation continues to be effective for end-stage liver disease, disease recurrence in the allograft is a controversial topic.
