  • Combined effects of smoking and HPV16 in oropharyngeal cancer
  • 2016
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press. - 1464-3685 .- 0300-5771. ; 45:3, s. 61-752

    • BACKGROUND: Although smoking and HPV infection are recognized as important risk factors for oropharyngeal cancer, how their joint exposure impacts on oropharyngeal cancer risk is unclear. Specifically, whether smoking confers any additional risk to HPV-positive oropharyngeal cancer is not understood.METHODS: Using HPV serology as a marker of HPV-related cancer, we examined the interaction between smoking and HPV16 in 459 oropharyngeal (and 1445 oral cavity and laryngeal) cancer patients and 3024 control participants from two large European multi-centre studies. Odds ratios and credible intervals [CrI], adjusted for potential confounders, were estimated using Bayesian logistic regression.RESULTS: Both smoking [odds ratio (OR [CrI]: 6.82 [4.52, 10.29]) and HPV seropositivity (OR [CrI]: 235.69 [99.95, 555.74]) were independently associated with oropharyngeal cancer. The joint association of smoking and HPV seropositivity was consistent with that expected on the additive scale (synergy index [CrI]: 1.32 [0.51, 3.45]), suggesting they act as independent risk factors for oropharyngeal cancer.CONCLUSIONS: Smoking was consistently associated with increase in oropharyngeal cancer risk in models stratified by HPV16 seropositivity. In addition, we report that the prevalence of oropharyngeal cancer increases with smoking for both HPV16-positive and HPV16-negative persons. The impact of smoking on HPV16-positive oropharyngeal cancer highlights the continued need for smoking cessation programmes for primary prevention of head and neck cancer.

  • Coeliac disease and asthma association in children : the role of antibiotic consumption
  • 2015
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 46:1, s. 115-122

    • The relationship between coeliac disease and asthma has been scarcely investigated. Infant antibiotic exposure has been linked to both diseases. We evaluated the association between childhood coeliac disease and asthma and the role of antibiotics in the first year of life. We followed a cohort of children born in 1995-2011 in the Friuli-Venezia Giulia region (Italy). Prescriptions for antibiotics in the first year of life and subsequent treated asthma were retrieved from drug prescription records; coeliac disease incident cases were identified from pathology reports, hospital discharges and exemption from prescription charges for clinical tests.We estimated incidence rate ratios (IRRs) using multivariate Poisson regression models. Among the 143 144 children, we identified 717 coeliac children and 34 969 asthmatics. Children with asthma were at increased risk of coeliac disease (IRR 1.46, 95% CI 1.25-1.67). Restricting the analysis to asthma that occurred before the diagnosis of coeliac disease, the excess risk disappeared, except for coeliac disease diagnosed after 5 years of age (IRR 1.37, 95% CI 1.09-1.71). Antibiotics were not a confounding factor in these associations. Childhood treated asthma and coeliac disease are significantly associated. This association is not confounded by antibiotic exposure in the first year of life and may be explained by other shared risk factors.

  • Risk of bacterial pneumonia and pneumococcal infection in youths with celiac disease - A population-based study
  • 2019
  • Ingår i: Digestive and Liver Disease. - : Elsevier. - 1590-8658 .- 1878-3562. ; 51:8, s. 1101-1105
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Assess the risk of hospitalizations for bacterial pneumonia or pneumococcal infections, in a cohort of young individuals with celiac disease (CD) compared to matched references.Study design: The cohort consists of 213,635 individuals, born in 1989-2012 and resident in Friuli-Venezia Giulia (Italy). Through pathology reports, hospital discharge records or co-payment exemptions, we identified 1294 CD patients and 6470 reference individuals matched by gender and birth year. We considered hospital admissions for first episodes of bacterial pneumonia and pneumococcal infections. Hazard ratios (HRs) for episodes after CD diagnosis were calculated with Cox regression and odds ratios (OR) for the ones before CD diagnosis with conditional logistic regression. Further analyses were performed on unvaccinated follow-up periods.Results: 14 CD patients (in 9450 person-years) and 42 references (in 48,335 person-years) experienced a first episode of bacterial pneumonia, with an increased risk among CD patients (HR 1.82; 95% CI 0.98-3.35). Risks of bacterial pneumonia were significantly increased before CD diagnosis and especially the year before CD diagnosis (OR 6.00, 95% CI 1.83-19.66). Risks of pneumococcal infections showed a non-significant increase in CD patients.Conclusions: CD children and youth showed an increased risk of bacterial pneumonia, especially in proximity to CD diagnosis. Anti-pneumococcal vaccination should be recommended to all young CD patients. (C) 2019 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

  • Risk of Fractures in Youths with Celiac Disease-A Population-Based Study
  • 2018
  • Ingår i: The Journal of Pediatrics. - : MOSBY-ELSEVIER. - 0022-3476 .- 1097-6833. ; 198, s. 117-120
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective To assess the risk of any fracture requiring hospital care in a cohort of individuals with celiac disease diagnosed in childhood/adolescence compared with reference individuals matched by age and sex. Study design Our study cohort consisted of 213 635 people born and residing in Friuli-Venezia Giulia Region, Italy, in 1989-2011. We selected, through pathology reports, hospital discharge records, or co-payment exemptions, 1233 individuals with celiac disease (aged 0-17 years at diagnosis) and compared them with 6167 reference individuals matched by sex and year of birth. Fractures were identified through hospital discharge records. We calculated hazard ratios (HRs) for any fracture after celiac disease diagnosis (or index date for reference individuals) with Cox regression and ORs for any fracture before celiac disease diagnosis with conditional logistic regression. Results During the follow-up period (maximum 23 years), 22 individuals with celiac disease (9394 person-years) and 128 reference individuals (47 308 person-years) experienced a fracture. giving an overall HR of 0.87 (95% CI 0.55-1.37). The risk was not modified by sex, age at diagnosis, or calendar period of diagnosis. We obtained similar HRs when excluding fractures occurring after the age of 18 years and adjusting for maternal education or vitamin D supplementation. The odds of previous fracture also did not differ between subjects with celiac disease and reference individuals (22 and 96 cases, respectively: OR 1.15: 95% CI 0.72-1.84). Conclusions We did not find any evidence of an increased risk of fractures during childhood and youth among patients with celiac disease.

  • Genome-wide association analyses identify new susceptibility loci for oral cavity and pharyngeal cancer
  • 2016
  • Ingår i: Nature Genetics. - 1061-4036 .- 1546-1718. ; 48:12, s. 1544-1550
  • Tidskriftsartikel (refereegranskat)abstract
    • We conducted a genome-wide association study of oral cavity and pharyngeal cancer in 6,034 cases and 6,585 controls from Europe, North America and South America. We detected eight significantly associated loci (P < 5 × 10(-8)), seven of which are new for these cancer sites. Oral and pharyngeal cancers combined were associated with loci at 6p21.32 (rs3828805, HLA-DQB1), 10q26.13 (rs201982221, LHPP) and 11p15.4 (rs1453414, OR52N2-TRIM5). Oral cancer was associated with two new regions, 2p23.3 (rs6547741, GPN1) and 9q34.12 (rs928674, LAMC3), and with known cancer-related loci-9p21.3 (rs8181047, CDKN2B-AS1) and 5p15.33 (rs10462706, CLPTM1L). Oropharyngeal cancer associations were limited to the human leukocyte antigen (HLA) region, and classical HLA allele imputation showed a protective association with the class II haplotype HLA-DRB1*1301-HLA-DQA1*0103-HLA-DQB1*0603 (odds ratio (OR) = 0.59, P = 2.7 × 10(-9)). Stratified analyses on a subgroup of oropharyngeal cases with information available on human papillomavirus (HPV) status indicated that this association was considerably stronger in HPV-positive (OR = 0.23, P = 1.6 × 10(-6)) than in HPV-negative (OR = 0.75, P = 0.16) cancers.
