Prevalence, predictors and age-related sexual and erectile dysfunction in patients with inflammatory bowel disease: A tertiary centre experience

INTRODUCTION

The impact of sexuality and quality of life (QOL) is one of the main concerns of IBD. Despite the obvious relevance of this problem, knowledge of the extent of sexual dysfunction (SD) in IBD is limited. Aim of this study was to assess the prevalence of SD and erectile dysfunction (ED), QOL their predictors, and their age-related dynamic in IBD patients.

METHODS

In this cross-sectional study, 202 IBD patients [122 male, 80 female, 133 Crohn's disease (CD), 69 ulcerative colitis (UC)] fulfilled International Index of Erectile Function (IIEF) or Female Sexual Functioning Index (FSFI). QOL was assessed using IBDQ-32 through bowel, systemic, emotional and social domains.

RESULTS

Prevalence of SD in men was 18%, ED 30.3% and SD in women 75%. Low QOL was present in 34.6% without gender difference (P = .253). In men, SD and ED were highest among 21-30 years and raising after 51 years of age. In women, SD was constantly highly prevalent, showing no decline over time. In multivariate analysis significant predictors of SD in men were CD phenotype, disease duration and emotional domain of IBDQ, of ED depression, emotional and bowel domain of IBDQ, and of SD in women emotional IBDQ domain.

CONCLUSION

Quality of sex life is a serious concern among IBD patients and is age related. Components that play a role in sexual functioning in IBD require more clarification and further development of screening and treatment guidelines for SD to provide better care in the IBD population.

Natural disease course of Crohn's disease during the first 5 years after diagnosis in a European population-based inception cohort: an Epi-IBD study

OBJECTIVE

The Epi-IBD cohort is a prospective population-based inception cohort of unselected patients with inflammatory bowel disease from 29 European centres covering a background population of almost 10 million people. The aim of this study was to assess the 5-year outcome and disease course of patients with Crohn's disease (CD).

DESIGN

Patients were followed up prospectively from the time of diagnosis, including collection of their clinical data, demographics, disease activity, medical therapy, surgery, cancers and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis.

RESULTS

In total, 488 patients were included in the study. During follow-up, 107 (22%) patients received surgery, while 176 (36%) patients were hospitalised because of CD. A total of 49 (14%) patients diagnosed with non-stricturing, non-penetrating disease progressed to either stricturing and/or penetrating disease. These rates did not differ between patients from Western and Eastern Europe. However, significant geographic differences were noted regarding treatment: more patients in Western Europe received biological therapy (33%) and immunomodulators (66%) than did those in Eastern Europe (14% and 54%, respectively, P<0.01), while more Eastern European patients received 5-aminosalicylates (90% vs 56%, P<0.05). Treatment with immunomodulators reduced the risk of surgery (HR: 0.4, 95% CI 0.2 to 0.6) and hospitalisation (HR: 0.3, 95% CI 0.2 to 0.5).

CONCLUSION

Despite patients being treated early and frequently with immunomodulators and biological therapy in Western Europe, 5-year outcomes including surgery and phenotype progression in this cohort were comparable across Western and Eastern Europe. Differences in treatment strategies between Western and Eastern European centres did not affect the disease course. Treatment with immunomodulators reduced the risk of surgery and hospitalisation.

Natural Disease Course of Ulcerative Colitis During the First Five Years of Follow-up in a European Population-based Inception Cohort-An Epi-IBD Study

BACKGROUND AND AIMS

Few population-based cohort studies have assessed the disease course of ulcerative colitis [UC] in the era of biological therapy and widespread use of immunomodulators. The aim of this study was to assess the 5-year outcome and disease course of patients with UC in the Epi-IBD cohort.

METHODS

In a prospective, population-based inception cohort of unselected patients with UC, patients were followed up from the time of their diagnosis, which included the collection of their clinical data, demographics, disease activity, medical therapy, and rates of surgery, cancers, and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis.

RESULTS

A total of 717 patients were included in the study. During follow-up, 43 [6%] patients underwent a colectomy and 163 [23%] patients were hospitalised. Of patients with limited colitis [distal to the left flexure], 90 [21%] progressed to extensive colitis. In addition, 92 [27%] patients with extensive colitis experienced a regression in disease extent, which was associated with a reduced risk of hospitalisation (hazard ratio [HR]: 0.5 95% CI: 0.3-0.8]. Overall, patients were treated similarly in both geographical regions; 80 [11%] patients needed biological therapy and 210 [29%] patients received immunomodulators. Treatment with immunomodulators was found to reduce the risk of hospitalisation [HR: 0.5 95% CI: 0.3-0.8].

CONCLUSIONS

Although patients in this population-based cohort were treated more aggressively with immunomodulators and biological therapy than in cohorts from the previous two decades, their disease outcomes, including colectomy rates, were no different. However, treatment with immunomodulators was found to reduce the risk of hospitalisation.

Health-related quality of life improves during one year of medical and surgical treatment in a European population-based inception cohort of patients with inflammatory bowel disease--an ECCO-EpiCom study

BACKGROUND & AIMS

Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe.

METHODS

The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up.

RESULTS

In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population.

CONCLUSION

Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

Environmental factors in a population-based inception cohort of inflammatory bowel disease patients in Europe--an ECCO-EpiCom study

BACKGROUND AND AIMS

The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients.

METHODS

The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors.

RESULTS

A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01).

CONCLUSIONS

In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

MDR1 polymorphisms are associated with inflammatory bowel disease in a cohort of Croatian IBD patients

BACKGROUND

Inflammatory bowel diseases (IBD) are chronic diseases of unknown etiology and pathogenesis in which genetic factors contribute to development of disease. MDR1/ABCB1 is an interesting candidate gene for IBD. The role of two single nucleotide polymorphisms, C3435T and G2677T remains unclear due to contradictory results of current studies. Thus, the aims of this research were to investigate the association of MDR1 polymorphisms, C3435T and G2677T, and IBD.

METHODS

A total of 310 IBD patients, 199 Crohn's disease (CD) patients and 109 ulcerative colitis (UC) patients, and 120 healthy controls were included in the study. All subjects were genotyped for G2677T/A and C3435T polymorphism using RT-PCR. In IBD patients, review of medical records was performed and patients were phenotyped according to the Montreal classification.

RESULTS

Significantly higher frequency of 2677T allele (p=0.05; OR 1.46, 95% CI (1.0-2.14)) and of the 3435TT genotype was observed among UC patients compared to controls (p=0.02; OR 2.12; 95% CI (1.11-4.03). Heterozygous carriers for C3435T were significantly less likely to have CD (p=0.02; OR 0.58, 95% CI (0.36-0.91)). Haplotype analysis revealed that carriers of 3435T/2677T haplotype had a significantly higher risk of having UC (p=0.02; OR 1.55; 95% CI (1.06-2.28)).

CONCLUSION

MDR1 polymorphisms are associated with both CD and UC with a stronger association with UC.

A pilot study of transrectal endoscopic ultrasound elastography in inflammatory bowel disease

Background

Using standard diagnostic algorithms it is not always possible to establish the correct phenotype of inflammatory bowel disease which is essential for therapeutical decisions. Endoscopic ultrasound elastography is a new endoscopic procedure which can differentiate the stiffness of normal and pathological tissue by ultrasound. Therefore, we aimed to investigate the role of transrectal ultrasound elastography in distiction between Crohn's disease and ulcerative colitis.

Methods

A total 30 Crohn's disease, 25 ulcerative colitis, and 28 non-inflammatory bowel disease controls were included. Transrectal ultrasound elastography was performed in all patients and controls. In all ulcerative coltis patients and 80% of Crohn's disease patients endoscopy was performed to assess disease activity in the rectum.

Results

Significant difference in rectal wall thickness and strain ratio was detected between patients with Crohn's disease and controls (p = 0.0001). CD patients with active disease had higher strain ratio than patients in remission (p = 0.02). In ulcerative colitis group a significant difference in rectal wall thickness was found between controls and patients with active disease (p = 0.03). A significant difference in rectal wall thickness (p = 0.02) and strain ratio (p = 0.0001) was detected between Crohn's disease and ulcerative colitis patient group. Crohn's disease patients with active disease had a significantly higher strain ratio compared to ulcerative colitis patients with active disease (p = 0.0001).

Conclusion

Transrectal ultrasound elastography seems to be a promising new diagnostic tool in the field of inflammatory bowel disease. Further study on a larger cohort of patients is needed to definitely assess the role of transrectal ultrasound elastography in inflammatory bowel disease.

Construction and validation of a web-based epidemiological database for inflammatory bowel diseases in Europe An EpiCom study

BACKGROUND

The EpiCom-study investigates a possible East-West-gradient in Europe in the incidence of IBD and the association with environmental factors. A secured web-based database is used to facilitate and centralize data registration.

AIM

To construct and validate a web-based inception cohort database available in both English and Russian language.

METHOD

The EpiCom database has been constructed in collaboration with all 34 participating centers. The database was translated into Russian using forward translation, patient questionnaires were translated by simplified forward-backward translation. Data insertion implies fulfillment of international diagnostic criteria, disease activity, medical therapy, quality of life, work productivity and activity impairment, outcome of pregnancy, surgery, cancer and death. Data is secured by the WinLog3 System, developed in cooperation with the Danish Data Protection Agency. Validation of the database has been performed in two consecutive rounds, each followed by corrections in accordance with comments.

RESULTS

The EpiCom database fulfills the requirements of the participating countries' local data security agencies by being stored at a single location. The database was found overall to be "good" or "very good" by 81% of the participants after the second validation round and the general applicability of the database was evaluated as "good" or "very good" by 77%. In the inclusion period January 1st -December 31st 2010 1336 IBD patients have been included in the database.

CONCLUSION

A user-friendly, tailor-made and secure web-based inception cohort database has been successfully constructed, facilitating remote data input. The incidence of IBD in 23 European countries can be found at www.epicom-ecco.eu.

Treatment of extensive subacute portal, mesenteric and ileocolic vein thrombosis with recombinant tissue plasminogen activator

Portal or/and mesenteric vein thrombosis is a rare condition with high mortality in an acute form. Therapy of thrombosis is not well defined, although there are some general guidelines that differ according to disease onset and clinical presentation. In acute thrombosis with bowel infarction, surgical resection with possible thrombolysis is advised. The best therapy for the subacute form is not known and the approach differs between centers. For chronic disease, prolonged anticoagulant therapy is recommended. Thrombolysis is well recognized in the treatment of acute ischemic coronary or cerebral diseases. Success of treatment is better if therapy is introduced within a few hours after symptoms have begun. We describe a 25-year-old patient with the subacute form of extensive portal, mesenteric and ileocolic vein thrombosis in the setting of underlying liver cirrhosis due to autoimmune disease. An aggressive therapeutic approach is advised, especially in patients who will eventually undergo liver transplantation, since portal and/or mesenteric vein thrombosis is relative contraindication for liver transplantation in the majority of transplant centers.

Discriminatory ability of calcaneal quantitative ultrasound in the assessment of bone status in patients with inflammatory bowel disease

A high incidence of bone disease in patients with inflammatory bowel disease (IBD) requires frequent monitoring of skeletal status and, for that reason, evaluation of radiation-free technology is an issue of interest. Our objective was to appraise the parameters of calcaneal quantitative ultrasound (QUS): broadband ultrasound attenuation (BUA), speed of sound (SOS) and stiffness index (QUI), and establish their t-score values to investigate discriminatory ability of QUS in IBD patients with metabolic bone disease. The study included 126 patients (Crohn's disease [n = 94] and ulcerative colitis [n = 32]), and 228 age- and sex-matched healthy volunteers. Bone status was evaluated on the same day by calcaneal QUS and dual-energy x-ray absorptiometry (DXA) at spine (L1-L4) and total hip. All QUS measurements were lower in patients compared with healthy controls (BUA p < 0.001; SOS p < 0.001; QUI p < 0.001) and correlated significantly but inversely with disease duration (r = -0.3, p = 0.002). There was no difference with respect to type of disease (Crohn's disease or ulcerative colitis) or corticosteroid therapy. All three QUS t-scores were significantly lower in patients who had previously sustained fragile fractures (n = 28) than in those without fracture in their history (n = 98) (t-scores: BUA -2.0 vs. -1.3, p = 0.008; SOS -2.1 vs. -1.4, p = 0.02: QUI -2.3 vs. -1.5, p = 0.009). Axial DXA was not significantly different between the fracture and nonfracture patients (-1.7 vs. -1.2, p = 0.1), whereas total hip DXA showed a discriminatory power between the two (-1.6 vs. -0.7, p = 0.001). Patients with t-score < -1.0 scanned by DXA were classified as bone disease. The sensitivity of QUS to identify bone disease was 93% and specificity 63%. The sensitivity of QUS to detect osteopenia was 84% and 72% for osteoporosis. Alternatively, lower negative QUS t-score cutoff <or= -1.8 identified 83% of osteoporosis at lumbar spine and 100% at total hip. All three QUS variables had t-scores less than -1.8 when osteoporosis was detected at both spine and hip. However, the subgroup of IBD patients with QUI t-score cutoff <or= -1.8 still included 26% of individuals with normal bone status. Calcaneal QUS measurements may identify patients with IBD who are at a higher risk of fracture independently of DXA measurements. However, QUS showed poor agreement with bone status scanned by DXA and a low discriminatory power between osteopenia and osteoporosis.

Lactobacillus acidophilus as a cause of liver abscess in a NOD2/CARD15-positive patient with Crohn's disease

INTRODUCTION

The development of a fistula and/or an abscess are major complications in patients with Crohn's disease. An abscess can involve any of the major viscera, including the liver and spleen.

CASE REPORT

A 27-year-old male patient with a 6-month history of NOD2/CARD15-positive Crohn's disease with stenosis of the terminal ileum, previously treated with corticosteroids, was admitted with fever, chills, diarrhea, fatigue and cachexia. Diagnostic work-up revealed sepsis, an abscess in the right hepatic lobe, multiple abdominal collections and right-sided pleural effusion. It was felt that his poor general condition prevented surgical intervention and complex conservative treatment was initiated. It consisted of total parenteral nutrition, antibiotics, percutaneous drainage of the liver abscess, and thoracocentesis. Pus and blood cultures showed Lactobacillus acidophilus. There was a gradual improvement in the patient's condition and the liver abscess decreased in diameter from 14 to 2 cm. Aminosalicylates and enteral nutrition were gradually introduced. The patient was discharged after 9 weeks in good general condition.

CONCLUSION

Although extremely rarely, L. acidophilus can cause hepatic abscess and sepsis. This can be explained by immunologic incompetence due to corticosteroid treatment of Crohn's disease.

NOD2/CARD15 mutations in Croatian patients with Crohn's disease: prevalence and genotype-phenotype relationship

BACKGROUND

Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract with variations in localization and behaviour. Mutations in the NOD2/CARD15 gene on chromosome 16q have been implicated in the pathogenesis of the disease and three main sequence variants, all single nucleotide polymorphisms (SNPs), have been identified in North American and European populations.

AIMS AND METHODS

As no data exist in the Croatian population, we consecutively collected a cohort of 136 CD patients and 91 healthy controls to determine the prevalence of NOD2/CARD15 mutations and their association with phenotypic expression of the disease. All patients and controls were genotyped for Arg702Trp (Hugot SNP8), Gly908Arg (Hugot SNP12), and Leu1007fsinsC (Hugot SNP13) and allele frequencies were compared between the Crohn's patients and controls. The correlation of NOD2/CARD15 genotypes with the phenotypic expression of Crohn's disease was further assessed by logistic regression analysis.

RESULTS

NOD2/CARD15 variants were found in 38/136 CD patients (27.9%) compared to 10/91 (10.9%) healthy controls (P = 0.0022). Allele frequencies in patients with CD were 13.97%, 4.4% and 11.76%, respectively, for SNP8, 12 and 13, compared to 5.49%, 1.12% and 4.40% in controls (P = 0.041, P = 0.162, P = 0.055). Six CD patients carried double mutations and, remarkably, we identified two homozygous mutants amongst the healthy control group. Surgery over the course of the disease and a younger age at onset of the disease were significantly more frequent in patients who were carriers of NOD2/CARD15 mutations.

CONCLUSIONS

This report on NOD2/CARD15 mutations in Croatian patients with CD demonstrates that this gene is also implicated in susceptibility to CD in the Croatian population. Phenotypic association showed a younger age at diagnosis and a higher need for surgery in patients carrying NOD2/CARD15 mutations. However, the prevalence is somewhat lower compared to other reports, likely due to a more prominent colonic inflammation.

Benign mesenchymal liver hamartoma in an adult male: a case report and review of the literature

Mesenchymal hamartoma of the liver is an uncommon benign lesion seen almost exclusively in children younger than two years of age. The first case was reported in 1903, and until now fewer than 200 cases have been reported. A 38-year-old male complaining of dull subcostal pain lasting for almost 10 months was found on abdominal ultrasound to have a focal lesion of the liver. He was referred to our Unit where imaging procedures (ultrasound and computed tomography) revealed a solid lesion, 8 centimeters in diameter, located in the IVb and V segments of the liver. There were no clear margins between the lesion and the gallbladder wall. Alpha-fetoprotein and carcinoembryonic antigen were within normal limits and carbohydrate antigen 19-9 was minimally elevated. There was no evidence of metastatic disease. Ultrasound-guided biopsy of the lesion was done and pathology report of a biopsy specimen suggested that the tumor was probably a benign mesenchymal hamartoma. The patient underwent a formal bi-segmentectomy (IVb and V segments) with cholecystectomy. Definitive pathology report confirmed the diagnosis of a benign mesenchymal hamartoma.
