Concordance regarding disease type and phenotypic characteristics among patients with familial inflammatory bowel disease. J Gastroenterol Hepatol 2020; 35:988-993. [PMID: 31674059 DOI: 10.1111/jgh.14913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 10/03/2019] [Accepted: 10/13/2019] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIMS The phenotypic concordance among familial cases of inflammatory bowel disease (IBD) has been rarely reported. Thus, the present study aimed to evaluate the concordance regarding disease type and phenotypic features in a large cohort of Korean patients with IBD. METHODS A total of 6647 patients with IBD who visited the Asan Medical Center between June 1989 and September 2016 were enrolled in the study. When at least two familial cases existed in our cohort, they were included in the concordance analysis (κ index). The concordance between younger and older members for IBD type [Crohn's disease (CD) and ulcerative colitis (UC)] and phenotypic characteristics such as disease extent and location, disease behavior, the use of medication, and need for surgery were evaluated. RESULTS A positive family history of IBD was noted in 216 patients with CD (7.0%) and in 238 patients with UC (6.7%). Of all patients, 167 consanguineous pairs in 146 families were identified. The crude concordance rate for IBD type was 82.6% with a κ index of 0.656 [95% confidence interval (CI): 0.545-0.768, good concordance]. There was mild concordance for disease location in CD (κ = 0.256; 95% CI: 0.007-0.505) and for the use of antitumor necrosis factor agents in UC (κ = 0.354; 95% CI: -0.049-0.757). The concordance for IBD type and several phenotypes in first-degree relative pairs was better than that in the entire pairs. CONCLUSIONS Disease type and phenotypic characteristics of patients with familial IBD may be anticipated.

Characteristics of inflammatory bowel disease in patients of Roma/Gypsy ethnicity. A case-control study. Dig Liver Dis 2019; 51:669-674. [PMID: 30606697 DOI: 10.1016/j.dld.2018.12.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 12/08/2018] [Accepted: 12/10/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Peculiarities of inflammatory bowel disease (IBD) have been explored in ethnic groups, such as Asians, Hispanics, and Afro-Americans, but not in other ethnic minorities, such as Roma/Gypsies. METHODS In a retrospective, hospital-based study, all adult Roma/Gypsy patients included in the IBD databases of seven Spanish centres were identified as cases. For each Roma/Gypsy patient, a Caucasian patient, matched for several demographic features, was searched as a control. Data on phenotypic features, therapeutic requirements, and familial aggregation were recorded. RESULTS Sixty-eight Roma/Gypsy patients were identified, 29 of them being women. The mean age at diagnosis of IBD was 24.9±9.5years, and the mean time elapsed since diagnosis was 96.6±72.2months. Roma/Gypsy IBD patients showed a significantly higher rate of familial aggregation (43%) than their Caucasian controls (9%) (p=0.00001). CD in Roma/Gypsies had more often a complicated pattern (mainly penetrating) while UC patients showed a marked trend to more often developing extraintestinal manifestations. In addition, Roma/Gypsy IBD patients had a somewhat greater need for immunosuppressants, biological agents or surgery. CONCLUSIONS These are the first data on IBD in Roma/Gypsy patients. Familial aggregation is the most prominent feature in these patients, suggesting a predominant role of genetics in its pathogenesis.

Abstract
BACKGROUND AND AIMS Despite numerous shared susceptibility loci between Crohn's disease and ulcerative colitis, the prevalence of family history among ulcerative colitis patients is not well-established and considered to be less prevalent. A systemic review and meta-analysis were conducted to estimate the prevalence of family history of inflammatory bowel disease in ulcerative colitis patients, and its effect on disease outcomes. METHODS PubMED was searched to identify studies reporting the prevalence of family history of inflammatory bowel disease among ulcerative colitis patients. Definitions of family history, study type, and subtypes of family history prevalence were abstracted, as were disease outcomes including age at ulcerative colitis diagnosis, disease location, surgery and extraintestinal manifestations. Pooled prevalence estimates were calculated using random effects models. RESULTS Seventy-one studies (86,824 patients) were included. The prevalence of a family history of inflammatory bowel disease in ulcerative colitis patients was 12% (95% confidence interval [CI] 11 to 13%; range 0-39%). Family history of ulcerative colitis (9%; 22 studies) was more prevalent than Crohn's disease (2%; 18 studies). Patients younger than 18years of age at time of diagnosis had a greater family history of inflammatory bowel disease (prevalence 15%, 95% CI: 11-20%; 13 studies). There were no differences in disease location, need for surgery, or extraintestinal manifestations among those with a family history, although very few studies reported on these outcomes. CONCLUSIONS Overall, 12% of ulcerative colitis patients have a family history of inflammatory bowel disease, and were more likely to have a family history of ulcerative colitis than Crohn's disease. Pediatric-onset ulcerative colitis patients were more likely to have a family history of inflammatory bowel disease.

Abstract
BACKGROUND & AIMS Disease outcome has been found to be poorer in familial inflammatory bowel disease (IBD) than in sporadic forms, but assessment of phenotypic concordance in familial IBD provided controversial results. We assessed the concordance for disease type and phenotypic features in IBD families. METHODS Patients with familial IBD were identified from the IBD Spanish database ENEIDA. Families in whom at least two members were in the database were selected for concordance analysis (κ index). Concordance for type of IBD [Crohn's disease (CD) vs. ulcerative colitis (UC)], as well as for disease extent, localization and behaviour, perianal disease, extraintestinal manifestations, and indicators of severe disease (i.e., need for immunosuppressors, biological agents, and surgery) for those pairs concordant for IBD type, were analyzed. RESULTS 798 out of 11,905 IBD patients (7%) in ENEIDA had familial history of IBD. Complete data of 107 families (231 patients and 144 consanguineous pairs) were available for concordance analyses. The youngest members of the pairs were diagnosed with IBD at a significantly younger age (p<0.001) than the oldest ones. Seventy-six percent of pairs matched up for the IBD type (κ=0.58; 95%CI: 0.42-0.73, moderate concordance). There was no relevant concordance for any of the phenotypic items assessed in both diseases. CONCLUSIONS Familial IBD is associated with diagnostic anticipation in younger individuals. Familial history does not allow predicting any phenotypic feature other than IBD type.

Abstract
OBJECTIVES The aim of this study was to evaluate any potential influence of a family history of inflammatory bowel disease (IBD) on the clinical phenotypes and the course of IBD in children. METHODS In this retrospective study, the notes of 411 children with the diagnosis of IBD, 244 (59.4%) with ulcerative colitis, 129 (31.4%) with Crohn's disease and 38 (9.2%) with IBD unclassified, who were admitted to our department between 1 January 1981 and 31 December 2007 were reviewed. The aim was to assess the prevalence of familial IBD and its impact on the age of disease onset, clinical phenotypes according to the Montreal classification, course and outcome of disease. The control group consisted of IBD children without a family history of IBD, who were admitted to the hospital during the same time period. RESULTS Thirty five (8.5%) children had a family history of IBD, (ulcerative colitis 6.6%, Crohn's disease 10.9% and IBD unclassified 13.2%). Sixty-eight percent of the 22 pairs of first-degree relatives were concordant for the clinical phenotype of disease. Significantly, more children with familial IBD had symptom onset and/or disease diagnosis before 5 years of age compared with sporadic IBD (P = 0.01 and P = 0.014, respectively); however, no differences were seen in sex, clinical phenotypes, need for aggressive treatment and/or surgery. CONCLUSION Children with familial IBD had earlier onset of disease compared with those with sporadic IBD. However, this had no significant impact on the clinical phenotypes, the course and/or the outcome of disease.

Abstract
BACKGROUND The incidence of Crohn's disease (CD) has been shown to be lower in Southern than in Northern Europe. Data on the frequency of the NOD2/CARD15 mutations for Mediterranean area are very scant. AIM To determine the incidence of CD from 1979 to 2002 in a township in Sicily together with the allele frequency of NOD2/CARD15 mutations in patients, family members and controls, and to determine the allele frequency of these mutations in sporadic CD from other areas of Sicily in comparison with a control population. METHODS Casteltermini is a small town close to Agrigento (Sicily) with a population of 9,130 inhabitants. All the diagnoses of inflammatory bowel disease (IBD) made from 1979 to 2002 were obtained through the local health authority. NOD2/CARD15 mutations were studied in 23 out of the 29 patients with CD in Casteltermini, in 60 family members and in 64 controls. NOD2/CARD15 was also studied in 80 sporadic cases of CD disease among Sicilians outside Casteltermini and 118 healthy controls. RESULTS From 1979 to 2002, 29 patients with CD and 13 patients with ulcerative colitis (UC) were registered. The 6-year mean incidence of CD ranged from 8.0 to 17 new cases for every 100,000 inhabitants, whereas the mean incidence of UC ranged from five new cases to 7.8 for every 100,000 inhabitants. The allele frequencies of NOD2/CARD15 mutations (L1007finsC, G908R, R702W) were 8.7, 4.3 and 8.7%, respectively, in CD cases; 5.0, 4.2 and 3.1% in family members; 1.6, 2.3 and 3.1% in controls. In sporadic Sicilian CD patients outside Casteltermini the allele frequency was 7.5, 8.1, 6.2% whereas in control population it was 3.3, 1.6, 1.6%. CONCLUSIONS A high incidence of CD compared with UC was observed in this small town in Southern Italy. The frequency of NOD2/CARD15 mutations in CD is similar to other Caucasian population studied so far.

Abstract
Ulcerative colitis (UC) is a multifactorial disorder with both genetic and environmental factors. HLA-B*52 and DRB1*1502 are reported to be strongly associated with UC in Japan. However, the actual susceptible gene has not been identified yet. In this study, to map precisely the susceptible locus for UC, we performed association mapping in the chromosome 6p using 24 microsatellite markers distributed over 16 Mb. A total of 183 patients with UC and 186 healthy controls (HC) were included in this study. In all, 15 markers around the human leukocyte antigen (HLA) region showed statistical significance in the genotypic differentiation test concerned with the allelic distribution between the UC and HC. Especially, the markers between the centromeric region of HLA class I and the telomeric region of class III showed remarkably low P-values and the allele239 of C2-4-4 in class I marker showed the strongest association (Pc=2.9 x 10(-9): OR=3.74, 95% CI=2.50-5.60). Furthermore, we found strong linkage disequilibrium (LD) between the allele239 of C2-4-4 and HLA-B*52 in haplotype analysis. These results provide evidence that, in Japanese, important determinants of disease susceptibility to UC may exist in HLA, especially between the centromeric region of class I and the telomeric region of class III, under the strong LD with HLA-B*52.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the intestine, commonly diagnosed as either ulcerative colitis (UC) or Crohn's disease (CD). Epidemiological studies have consistently shown that both genetic and environmental factors influence the pathogenesis of IBD. A number of genome scans have been conducted in cohorts of IBD families with affected sibling pairs (ASPs) to identify chromosomal regions that harbour IBD susceptibility genes. Several putative linked loci have been identified, including two loci on chromosomes 16 and 12, IBD1 and IBD2, which have subsequently been replicated by independent region-specific studies. We have conducted both a replication study on another linkage region, chromosome 6p (IBD3), and extension studies on two other regions, chromosomes 3p and 7q. Microsatellite markers across each region were genotyped in 284 IBD ASPs from 234 families. A nonparametric peak multipoint LOD score of 3.0 was observed near D6S291, replicating the previous linkage to chromosome 6p (IBD3). Nominal evidence of linkage was observed at both the 3p and 7q regions.
