- 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.

- BACKGROUND & AIMS: Diagnosis of inflammatory bowel diseases (IBD) is increasing among elderly persons (60 years or older). We performed a nationwide population-based study to estimate incidence and treatment.METHODS: We identified all incident IBD cases in Sweden, from 2006 through 2013, using national registers, and up to 10 matched population comparator subjects. We collected data on the patients' health care contacts and estimated incidence rates, health service burden, pharmacologic treatments, extra-intestinal manifestations, and surgeries in relation to age of IBD onset (pediatric, less than 18 years; adults, 18-59 years; elderly, 60 years or older).RESULTS: Of 27,834 persons diagnosed with incident IBD, 6443 (23%) had a first diagnosis of IBD at 60 years or older, corresponding to an incidence rate of 35/100,000 person-years (10/100,000 person-years for Crohn's disease, 19 /100,000 person-years for ulcerative colitis, and 5/100,000 person-years for IBD unclassified). During a median follow-up period of 4.2 years (range 0-9 years), elderly patients had less IBD-specific outpatient health care but more IBD-related hospitalizations and overall health care use than adult patients with IBD. Compared to patients with pediatric or adult onset, elderly patients used fewer biologics and immunomodulators, but more systemic corticosteroids. Occurrence of extra-intestinal manifestations was similar in elderly and adult patients, but bowel surgery was more common in the elderly (13% after 5 years vs 10% in adults) (P<.001). The absolute risk of bowel surgery was higher in the elderly than in the general population, but in relative terms, the risk increase was larger in younger age groups.CONCLUSIONS: In a nationwide cohort study in Sweden, we associated diagnosis of IBD at age 60 years or older with a lower use of biologics and immunomodulators but higher absolute risk of bowel surgery, compared to diagnosis at a younger age. The large differences in pharmacological treatment of adults and elderly patients are not necessarily due to a milder course of disease and warrant further investigation.

- Background and Aims: Crohn's disease may affect the ability to work and lead to permanent disability. We aimed to investigate work loss in prevalent patients.Methods: We identified patients with Crohn's disease and general population comparators matched by sex, birth year, healthcare region and education. We assessed days of sick leave and disability pension retrieved from the Swedish Social Insurance Agency and estimated the absolute and relative risk of receiving disability pension [minimum 25% work impairment].Results: In 2014, the 20638 Crohn's disease patients [median age 44 years] had more than twice as many mean lost workdays [disability pension: 44; sick leave: 19] as the 102038 comparators [disability pension: 20; sick leave: 8], mean difference 35 days [95% confidence interval 33-37]. However, the majority had no lost workdays [68% of patients and 85% of comparators]. The proportion of patients receiving disability pension was 15% (6.5% in the comparators, risk ratio 2.34 [2.25-2.43]) and was higher in all subgroups, especially in female patients [28% vs 13% in the comparators], in those with ≤9 years of education [41% vs 23%] and in ages 60-64 years [46% vs 25%]. The relative risk of disability pension within the patient cohort [adjusted for age, sex, region and education] was higher in patients with complicated disease behaviour, extraintestinal manifestations, need of surgery or treatment with biologics. The differences between patients and comparators remained when comparing other calendar years [2006-2013].Conclusion: Work loss was found in approximately one-third of patients. The mean number of lost workdays was twice as high as in the comparators.

- Liver biopsy is an important procedure in the investigation of liver disease. We examined pregnancy outcomes in women who underwent liver biopsy during pregnancy. In a nationwide population-based cohort study we linked data from the Swedish Medical Birth Registry (for births between 1992 and 2011) with those from the Swedish Patient Registry. We identified 23 pregnancies exposed to liver biopsy. We calculated relative risks (RRs) for adverse pregnancy outcomes according to liver biopsy status using 1,953,887 unexposed pregnancies with and without a record of liver disease as reference. Our main outcome measures were stillbirth and preterm birth. There were no stillbirths in pregnancies exposed to liver biopsies compared with 0.3% stillbirths in unexposed pregnancies. 3/23 (13%) exposed pregnancies were preterm (RR=2.6; 95%CI=0.9-7.5). Compared with women with a record of liver disease, preterm birth was not increased in those exposed to liver biopsy (RR=0.9; 95%CI=0.1-6.0). Except for an increased risk of small for gestational age birth in pregnancies exposed to liver biopsy (RR=5.2; 95%CI=1.8-14.8), other adverse pregnancy outcomes were independent of liver biopsy status when the analysis was restricted to women with a diagnosis of liver disease. Compared with unexposed sibling pregnancies, pregnancies with a liver biopsy were 7 days shorter, but birth weights did not differ between the siblings (-67g; p>0.05).Apart from a moderately increased risk of preterm birth and small for gestational age, there was no association between liver biopsy during pregnancy and adverse pregnancy outcome. Potential excess risks should be weighed against the advantages of having a liver biopsy that may influence clinical management of the patient indirectly influencing fetal health.

- OBJECTIVE: Microscopic colitis (MC), encompassing collagenous colitis (CC) and lymphocytic colitis (LC), is a diagnosis which relies on histopathologic criteria. This report examines the validity of having a diagnosis of MC in Swedish pathology registers.METHODS: We reviewed patient charts from 215 randomly selected individuals from 15 pathology departments in five healthcare regions in Sweden with a relevant histopathology code for MC on colon biopsies. Information on clinical symptoms and laboratory data were obtained from medical chart review. We obtained sufficient data on 211 individuals for calculating positive predictive values (PPVs) for MC.RESULTS: In total, 200/211 patients with a histopathology diagnosis of MC were confirmed as also having a clinical diagnosis of MC after chart review, yielding a PPV of 95% (95%CI =91-97%). The PPV for CC was 95% (95%CI =87-98%) and 85% for LC (95%CI =78-90%). The median age at biopsy was 67 years (range 17-90 years), and 72% (n = 154) were women. The most common symptoms in patients with MC histopathology were diarrhea (96% of patients), weight loss (24%) and abdominal pain (13%). Four percent (4/111) of patients with available data on stool culture were positive for gastrointestinal pathogens (none had Clostridium difficile). In 81 patients with available celiac serology, five (6%) were positive. Twenty-six percent of all patients had at least one other autoimmune disease, the most frequent being hypothyroidism (8%) and celiac disease (6%).CONCLUSIONS: This study found a high validity for MC as recorded in Swedish pathology registers.

- BACKGROUND & AIMS: Microscopic colitis is a chronic inflammatory disorder of the colon primarily affecting postmenopausal women. However, the relation between hormonal determinants, including reproductive and menopausal factors, and risk of microscopic colitis has yet to be characterized.METHODS: We collected data from 227,766 women who participated in the Nurses' Health Study (NHS) and the NHSII without a baseline history of microscopic colitis. Reproductive and menopausal factors were assessed in 1988 in the NHS and 1989 in the NHSII and updated biennially. Cases of microscopic colitis were confirmed through review of pathology records. We used Cox proportional hazards modeling to estimate hazard ratios and 95% confidence intervals.RESULTS: Through 2014 in the NHS and 2015 in the NHSII, we confirmed 275 incident cases of microscopic colitis over 5,147,282 person-years. Compared with never use, current use of menopausal hormone therapy was associated with increased risk of microscopic colitis (multivariable-adjusted hazard ratio 2.64; 95% confidence interval 1.78-3.90). The risk increased with longer duration of use (P for trend < .0001) and decreased after discontinuation (P for trend = .002). The association did not differ according to disease subtype (P for heterogeneity = .34). Similarly, ever use of oral contraceptives was associated with increased risk of microscopic colitis (multivariable-adjusted hazard ratio 1.57; 95% confidence interval 1.16-2.13). There were no associations between age at menarche, parity, age at first birth, age at menopause, or menopause type and incident microscopic colitis.CONCLUSIONS: In 2 large prospective cohort studies, we observed an association between exogenous hormone use and incident microscopic colitis. Further studies are needed to determine the mechanisms underlying these associations.

- Introduction: Long-term data on the influence of smoking on risk of microscopic colitis are limited. We therefore sought to examine and characterize the association between smoking and risk of incident microscopic colitis in two large prospective cohorts of women.Methods: We conducted a prospective study of 231,015 women enrolled in the Nurses' Health Study (NHS) and NHSII. Information regarding smoking, other lifestyle factors, and medications were collected biennially from 1976 to 2012 in NHS and 1989 to 2013 in NHSII. Incident cases of microscopic colitis were confirmed through physician medical record review. We used Cox proportional hazards modeling to examine the association between smoking and risk of microscopic colitis.Results: We documented 166 incident cases of microscopic colitis over 6,122,779 person-years of follow up. Compared to non-smokers, the multivariable-adjusted hazard ratio (HR) for microscopic colitis was 2.52 (95% CI 1.59 - 4.00) amongst current smokers and 1.54 (95% CI 1.09 - 2.17) amongst past smokers. The risk increased with higher pack-years of smoking (Ptrend = 0.001) and diminished following smoking cessation (Ptrend = 0.017). Current smoking appeared to be more strongly associated with risk of collagenous colitis (3.68; 95% CI 1.94 - 6.97) than lymphocytic colitis (HR 1.71; 95% CI 0.83 - 3.53).Conclusion: In two large prospective cohort studies, we observed an association between current smoking and risk of microscopic colitis. Risk of microscopic colitis appeared to increase with higher pack-years and diminish following smoking cessation. Future studies focused on characterizing the biologic mechanisms underlying these associations are warranted.

- Background: Patients with celiac disease (CD) are at increased risk of certain infections, but it is unknown if mucosal healing influences this risk.Methods: We collected data on 29,096 individuals with CD (equal to villous atrophy) through Sweden's 28 pathology departments undergoing biopsy 1969-2008. Through the Swedish Patient Register we obtained information on any infection and specifically sepsis, streptococcal infection, influenza, Clostridium difficile, herpes zoster and pneumococcal infection up until December 2009. We used Cox regression to calculate hazard ratios (HRs) for the risk of future diagnosis of infection according to mucosal healing on follow-up biopsy (persistent villous atrophy vs mucosal healing).Results: Of 5598 CD individuals with no record of any infections before follow-up biopsy, 45% had persistent villous atrophy, 619 (24%) of them had a later infection, compared to 579 (19%) in those with mucosal healing (p<0.01); the yearly incidence was 2.1% in both groups. Adjusting for age, sex, calendar period, time between biopsies and education, persistent villous atrophy was however not associated with later infection overall (HR=0.99; 95% CI=0.88-1.11) or with any of the specific infections.Conclusions: In CD, mucosal healing does not influence the risk of serious infection requiring hospital-based medical attention.
