In patients with HCV genotypes 2 and 3, sofosbuvir plus ribavirin was administered for 12 weeks in patients with genotype 2 and for 24 weeks in those with genotype 3. Rates of sustained virologic response were 93% in patients with genotype 2 and 85% in those with genotype 3. Of the six main genotypes of the hepatitis C virus (HCV), genotypes 2 and 3 account for approximately 30% of chronic infections worldwide. 1 Although these two genotypes have historically been grouped together in treatment guidelines and clinical trials, 2 , 3 accumulating evidence suggests that there are important clinical differences between them. 1 , 4 , 5 HCV genotype 3 infection is associated with a higher incidence of hepatic steatosis, more rapid progression of fibrosis, and possibly a greater risk of hepatocellular carcinoma than is HCV genotype 2 infection. 6 Moreover, patients with HCV genotype 3 infection are less responsive to peginterferon-based treatment than are patients . . .

Objective The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East–West gradient in the incidence of IBD in Europe exists. Design A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. Results 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100 000 in 2010 for CD were 6.5 (range 0–10.7) in Western European centres and 3.1 (range 0.4–11.5) in Eastern European centres, for UC 10.8 (range 2.9–31.5) and 4.1 (range 2.4–10.3), respectively, and for IBDU 1.9 (range 0–39.4) and 0 (range 0–1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. Conclusions An East–West gradient in IBD incidence exists in Europe. Among this inception cohort—including indolent and aggressive cases—international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

Several authors have described an association between celiac disease (CD) and ulcerative colitis (UC), but this has not yet been established. The aim of our study was to examine the frequency of antigliadin antibodies (AGA), antireticulin antibodies (ARA) and antiendomysium (AEM) antibodies in the sera of patients with UC (n = 50), and to evaluate their correlation with clinical variables. Sixteen patients with irritable bowel syndrome (IBS) and 37 healthy individuals served as controls. An enzyme-linked immunosorbent assay was used for the detection of IgA- and IgG-type AGA. IgG-type ARA were determined by an indirect immunofluorescence assay (IIF) using rat kidney, liver, and stomach as antigen substrates. IgA-type AEM antibodies were measured by IIF, using cryostat sections from human umbilical cord. Seventeen of the 50 patients with UC (34%) were positive for IgA- or/and IgG-type AGA. There was no correlation between the presence of AGA and the duration or extent of the disease, or disease activity. However, 5 patients with both IgA- and IgG-types of AGA had extensive colitis. Only 2 controls (4%) were positive for IgG-AGA. ARA and AEM were not detected in any individuals studied. Since the ARA and AEM test results were negative, we conclude that none of the UC patients in this series had CD.

No direct comparison of health care cost in patients with inflammatory bowel disease across the European continent exists. The aim of this study was to assess the costs of investigations and treatment for diagnostics and during the first year after diagnosis in Europe.MethodsThe EpiCom cohort is a prospective population-based inception cohort of unselected inflammatory bowel disease patients from 31 Western and Eastern European centers. Patients were followed every third month from diagnosis, and clinical data regarding treatment and investigations were collected. Costs were calculated in euros (€) using the Danish Health Costs Register.ResultsOne thousand three hundred sixty-seven patients were followed, 710 with ulcerative colitis, 509 with Crohn's disease, and 148 with inflammatory bowel disease unclassified. Total expenditure for the cohort was €5,408,174 (investigations: €2,042,990 [38%], surgery: €1,427,648 [26%], biologicals: €781,089 [14%], and standard treatment: €1,156,520 [22%)]). Mean crude expenditure per patient in Western Europe (Eastern Europe) with Crohn's disease: investigations €1803 (€2160) (P = 0.44), surgery €11,489 (€13,973) (P = 0.14), standard treatment €1027 (€824) (P = 0.51), and biologicals €7376 (€8307) (P = 0.31). Mean crude expenditure per patient in Western Europe (Eastern Europe) with ulcerative colitis: investigations €1189 (€1518) (P < 0.01), surgery €18,414 (€12,395) (P = 0.18), standard treatment €896 (€798) (P < 0.05), and biologicals €5681 (€72) (P = 0.51).ConclusionsIn this population-based unselected cohort, costs during the first year of disease were mainly incurred by investigative procedures and surgeries. However, biologicals accounted for >15% of costs. Long-term follow-up of the cohort is needed to assess the cost-effectiveness of biological agents.

Circulating IgA-antigliadin antibodies (IgA-AGA) are often found in patients with IgA nephropathy (NP). IgA-AGA are sensitive markers of an abnormal immune system reaction to gluten, seen particularly in patients with celiac disease. However, a lack of IgA-antireticulin and IgA-antiendomysium antibodies and often jejunal mucosal atrophy of patients with IgA NP suggest that most patients do not have latent celiac disease. To examine the relationship between IgA-AGA and clinical data, enzyme-linked immunosorbent assays for IgA-AGA were performed in 28 patients with IgA NP and in 50 healthy persons. The results were calculated in arbitrary units (AU). The cutoff level for a negative or a positive test was found to be 60 AU, calculated according to the AGA test result (mean + 3 SD) in 50 healthy persons. The following clinical data were assessed: age, gender, disease duration, daily proteinuria, blood pressure, serum creatinine, and creatinine clearance. Control sera were negative for IgA-AGA. Positive IgA-AGA tests were observed in 14 of the 28 patients (p < 0.0001 vs. controls) and high levels of IgA-AGA (AU >90) in 6 of the 28 patients (p < 0.001 vs. controls). The mean duration of the disease of the patients with positive IgA-AGA was significantly longer as compared with the patients who had a negative antibody test. IgA-AGA correlated with age (p < 0.05, r = 0.56), disease duration (p < 0.05, r = 0.40), and blood pressure (p < 0.05, r = 0.48). Antireticulin and antiendomysium antibody tests were negative in all patient and control sera. We conclude that IgA-AGA are associated with the progression of IgA NP. Our findings support the current concept about the pathogenesis of IgA NP, where the defective IgA production itself may be the primary and intestinal lesions as well as the production of IgA-AGA the secondary phenomenon.
