ABSTRACT

INTRODUCTION: Infliximab (IFX) therapy is efficacious for inducing and maintaining symptomatic remission in patients with Crohn's disease (CD), but whether this benefit results in reduced hospitalization rates and therefore may improve patients' quality of life in an economically sensible way is conflicting so far. METHODS: We conducted a noninterventional, multicenter, open-label, prospective study to evaluate the effect of originator IFX treatment on patient-reported outcomes and disease-related hospitalizations in adult CD patients in Germany treated for the first time with IFX according to label. RESULTS: Two hundred and ninety-four patients were included in the study. We observed a statistically significant reduction in the number of CD-related hospitalizations from the year before baseline (mean 1.00 per patient, SD ± 0.93) to the mean value of the 1st (0.62, SD ± 0.95) and 2nd year (0.32, SD ± 0.75) of the observation period (p < 0.0001). After 3 months of IFX therapy, work productivity and activity increased by an average of 12.6 and 17.1%, respectively. Patient's clinical outcome was markedly improved as the total CD activity index (CDAI) sum score continuously decreased from baseline to month 24 and the mean score of the total inflammatory bowel disease questionnaire (IBDQ) changed substantially from 141 at baseline to 172 after 24 months of IFX treatment. Additionally, the number of work incapacity days declined. Recently, no new safety issues of IFX have been identified. CONCLUSION: In this large, prospective, multicenter study on disease-related hospitalization rates, work productivity, capacity for daily activities, and HRQoL in patients with CD, IFX significantly reduces their hospitalization rates and improves work productivity, daily activity, and quality of life over 24 months.

ABSTRACT

BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory bowel disease with recurrent episodes of debilitating symptoms negatively affecting work productivity and health-related quality of life (HRQoL). The use of biologics in UC treatment improves work and HRQoL but prospective long-term data concerning the treatment with TNFα inhibitor golimumab in UC patients are still rare. Therefore, our study aimed to evaluate the change in work productivity, capacity for daily activities and HRQoL in UC patients treated with golimumab in Germany. METHODS: Using the Work Productivity and Activity Impairment questionnaire, the change in work productivity and in capacity for daily activities after 3 months and over the whole observational period of 24 months were assessed (both primary endpoints). Disease-specific and health-related quality of life (QoL) were analyzed with the Inflammatory Bowel Disease Questionnaire (IBDQ), the Short-Form 12 Health Survey Questionnaire (SF-12), and the Partial Mayo Score (secondary endpoints). Further, disease-related hospitalization rates were assessed. RESULTS: This prospective non-interventional study included 286 patients. Thereof, 212 patients were employed at baseline (modified intention to treat analysis set employed at baseline, mITTe). 61.3% of the mITTe patients had moderate and 17.0% had severe UC. Three months after initiation of golimumab therapy, total work productivity impairment (TWPI) score and activity impairment score improved significantly from baseline with a mean change of - 17.3% (p < 0.0001) and - 14.4% (p < 0.0001), respectively. Results persisted over 24 months (mean change TWPI score: - 24.5%, mean change activity impairment score: - 30.0%). Disease- and health-related QoL also improved significantly under golimumab treatment as indicated by increased IBDQ [mean change: 28.0 (SD: ± 36.1, month 3), 42.1 (SD: ± 39.5, month 24)] and SF-12 scores [PCS-12: 45.9 (SD: ± 8.5), MCS-12: 4.9 (SD: ± 10.6, month 3), PCS-12: 5.9 (SD: ± 9.0), MCS-12: 6.4 (SD: ± 11.1, month 24)]. Disease-related hospitalization rate decreased from 16.0% (BL) to 4.3% at month 24 and the mean number of missed working days due to UC decreased from 8.2 (SD: 17.6, BL) to 0.7 (SD: 2.1) after golimumab induction. CONCLUSIONS: Golimumab leads to notable long-term improvements in work productivity, daily activity, HRQoL, and disease-related hospitalization rates in patients with moderate to severe UC.

ABSTRACT

BACKGROUND: The introduction of biologics has revolutionized the management of the chronic inflammatory bowel disease, ulcerative colitis (UC), with many patients experiencing significant improvements not only in their symptoms but in other outcomes relevant to individuals and society as a whole. In Germany, there are no prospective data > 3 mo that assess the work productivity, daily activities and quality of life (QoL) of patients with moderate-to-severe UC treated with golimumab. AIM: To assess change in work productivity, capacity for daily activities and QoL in UC patients treated with golimumab in Germany. METHODS: The validated Work Productivity Activity Impairment (WPAI) Questionnaire was used to analyze the change in work productivity, the capacity for daily activities after three months (primary endpoint) and disease specific and health related QoL (HRQoL) up to 1 year (secondary endpoints). The changes in work productivity and activity impairment were evaluated every three months until month twelve compared to baseline. Disease-specific and health-related QoL were assessed with the inflammatory bowel disease questionnaire and with the short-form 12 health survey questionnaire (SF-12). RESULTS: This prospective non-interventional study included 287 patients. The analysis population was comprised of 282 patients who had completed at least two visits. At baseline, 61% of patients had moderate UC and 18% had severe UC. Furthermore, 75% of patients worked full-time or part-time at baseline. A total of 212 patients who were employed at the start of the study (employed population) were evaluated for the primary endpoint. Golimumab significantly reduced all WPAI sub-scores compared to baseline after three, six, nine and twelve months after the start of treatment (P < 0.0001). In addition, disease-specific QoL and HRQoL, as measured by the SF-12 questionnaire, improved significantly with golimumab at all evaluation times (P < 0.0001 in each case vs baseline). CONCLUSION: Treatment of moderate-to-severe UC with golimumab leads to significant improvements in patient´s work productivity, daily activity and QoL over twelve months.

ABSTRACT

Cutaneous squamous cell carcinoma (SCC) is one of the most common cancers in the United States. Previous genome-wide association studies (GWAS) have identified 14 single nucleotide polymorphisms (SNPs) associated with cutaneous SCC. Here, we report the largest cutaneous SCC meta-analysis to date, representing six international cohorts and totaling 19,149 SCC cases and 680,049 controls. We discover eight novel loci associated with SCC, confirm all previously associated loci, and perform fine mapping of causal variants. The novel SNPs occur within skin-specific regulatory elements and implicate loci involved in cancer development, immune regulation, and keratinocyte differentiation in SCC susceptibility.

ABSTRACT

BACKGROUND: Peanut allergy (PA) is a complex disease with both environmental and genetic risk factors. Previously, PA loci were identified in filaggrin (FLG) and HLA in candidate gene studies, and loci in HLA were identified in a genome-wide association study and meta-analysis. OBJECTIVE: We sought to investigate genetic susceptibility to PA. METHODS: Eight hundred fifty cases and 926 hyper-control subjects and more than 7.8 million genotyped and imputed single nucleotide polymorphisms (SNPs) were analyzed in a genome-wide association study to identify susceptibility variants for PA in the Canadian population. A meta-analysis of 2 phenotypes (PA and food allergy) was conducted by using 7 studies from the Canadian, American (n = 2), Australian, German, and Dutch (n = 2) populations. RESULTS: An SNP near integrin α6 (ITGA6) reached genome-wide significance with PA (P = 1.80 × 10-8), whereas SNPs associated with Src kinase-associated phosphoprotein 1 (SKAP1), matrix metallopeptidase 12 (MMP12)/MMP13, catenin α3 (CTNNA3), rho GTPase-activating protein 24 (ARHGAP24), angiopoietin 4 (ANGPT4), chromosome 11 open reading frame (C11orf30/EMSY), and exocyst complex component 4 (EXOC4) reached a threshold suggestive of association (P ≤ 1.49 × 10-6). In the meta-analysis of PA, loci in or near ITGA6, ANGPT4, MMP12/MMP13, C11orf30, and EXOC4 were significant (P ≤ 1.49 × 10-6). When a phenotype of any food allergy was used for meta-analysis, the C11orf30 locus reached genome-wide significance (P = 7.50 × 10-11), whereas SNPs associated with ITGA6, ANGPT4, MMP12/MMP13, and EXOC4 and additional C11orf30 SNPs were suggestive (P ≤ 1.49 × 10-6). Functional annotation indicated that SKAP1 regulates expression of CBX1, which colocalizes with the EMSY protein coded by C11orf30. CONCLUSION: This study identifies multiple novel loci as risk factors for PA and food allergy and establishes C11orf30 as a risk locus for both PA and food allergy. Multiple genes (C11orf30/EMSY, SKAP1, and CTNNA3) identified by this study are involved in epigenetic regulation of gene expression.

ABSTRACT

Maternal nutrition during pregnancy and postnatal offspring nutrition may influence offspring traits. We investigated the effects of maternal and postweaning offspring dietary nitrogen on immune function and hematology in two species of rodent: the hispid cotton rat (Sigmodon hispidus), a primarily herbivorous rodent, and the fulvous harvest mouse (Reithrodontomys fulvescens), an omnivore. These two species responded differently to the same levels of treatment, with cotton rats primarily influenced by maternal diet and harvest mice by postweaning offspring diet. Cotton rats born to mothers on high-nitrogen diets had lower values of mean corpuscle volume and hemoglobin and greater concentrations of serum immunoglobulins. Spleen size, cell-mediated immune response, and the number of splenocytes and thymic platelets were lower in cotton rats born to mothers on low- and high-nitrogen diets. High-nitrogen offspring diet increased kidney and liver mass in cotton rats. Harvest mice had increased kidney mass on high-nitrogen maternal diets; however, changes in offspring diet after weaning reduced hematological parameters in individuals fed low-nitrogen diets. Body length was also affected, with harvest mice born to mothers fed low- and high-nitrogen diets having shorter lengths. Splenocyte cellular activity was greater in offspring born to mothers on high-nitrogen diets in both species.

ABSTRACT

BACKGROUND: The aim of this substudy of the EUROINJECT-ONE double-blind randomized trial was to analyze changes in myocardial perfusion in NOGA-defined regions with intramyocardial injections of plasmid encoding plasmid human (ph)VEGF-A(165) using an elaborated transformation algorithm. METHODS AND RESULTS: After randomization, 80 no-option patients received either active, phVEGF-A165 (n=40), or placebo plasmid (n=40) percutaneously via NOGA-Myostar injections. The injected area (region of interest, ROI) was delineated as a best polygon by connecting of the injection points marked on NOGA polar maps. The ROI was projected onto the baseline and follow-up rest and stress polar maps of the 99m-Tc-sestamibi/tetrofosmin single-photon emission computed tomography scintigraphy calculating the extent and severity (expressed as the mean normalized tracer uptake) of the ROI automatically. The extents of the ROI were similar in the VEGF and placebo groups (19.4+/-4.2% versus 21.5+/-5.4% of entire myocardium). No differences were found between VEGF and placebo groups at baseline with regard to the perfusion defect severity (rest: 69+/-11.7% versus 68.7+/-13.3%; stress: 63+/-13.3% versus 62.6+/-13.6%; and reversibility: 6.0+/-7.7% versus 6.7+/-9.0%). At follow-up, a trend toward improvement in perfusion defect severity at stress was observed in VEGF group as compared with placebo (68.5+/-11.9% versus 62.5+/-13.5%, P=0.072) without reaching normal values. The reversibility of the ROI decreased significantly at follow-up in VEGF group as compared with the placebo group (1.2+/-9.0% versus 7.1+/-9.0%, P=0.016). Twenty-one patients in VEGF and 8 patients in placebo group (P<0.01) exhibited an improvement in tracer uptake during stress, defined as a >or =5% increase in the normalized tracer uptake of the ROI. CONCLUSIONS: Projection of the NOGA-guided injection area onto the single-photon emission computed tomography polar maps permits quantitative evaluation of myocardial perfusion in regions treated with angiogenic substances. Injections of phVEGF A165 plasmid improve, but do not normalize, the stress-induced perfusion abnormalities.

ABSTRACT

The contribution of small mammals to nitrogen cycling could have repercussions for the producer community in the maintaining or perhaps magnifying of nitrogen availability. Our objective was to model nitrogen outputs (deposition of feces and urine) of small mammals in an old-field ecosystem and estimate the amount of fecal and urinary nitrogen deposited annually. To address this objective, we used models from laboratory studies and combined these with data from field studies to estimate dietary nitrogen and monthly and annual nitrogen outputs from fecal and urine deposition of five rodent species. The models accounted for monthly fluctuations in density and biomass of small-mammal populations. We estimated that the minimal amount of nitrogen deposited by rodents was 1.0 (0.9-1.1) and 2.7 (2.6-2.9) kg Nha(-1) year(-1) from feces and urine, respectively, for a total contribution of 3.7 (3.5-4.0) kg Nha(-1) year(-1). Hispid cotton rats (Sigmodon hispidus) accounted for >75% of the total nitrogen output by small mammals. Our estimates of annual fecal and urinary nitrogen deposited by rodents were comparable to nitrogen deposits by larger herbivores and other nitrogen fluxes in grassland ecosystems and should be considered when assessing the potential effects of herbivory on terrestrial nitrogen cycles.
