- INTRODUCTION: Celiac disease (CD) is associated with many immune-mediated conditions, but a definitive epidemiological association between CD and juvenile idiopathic arthritis (JIA) or rheumatoid arthritis (RA) has not been established. We quantified the risk of JIA and RA among patients with CD using a population-based cohort.METHODS: We identified patients diagnosed with biopsy-proven CD between 2004 and 2017 using data from a national histopathology cohort in Sweden. Each patient was matched by age, sex, calendar year, and geographic region to reference individuals in the general population. We calculated the incidence and estimated the relative risk, through Cox proportional hazards models, of JIA in individuals with CD aged ≥18.RESULTS: We identified 24,014 individuals with CD who were matched to 117,397 reference individuals from the general population. Among individuals aged <18, the incidence rate of JIA was 5.9 per 10,000 person-years in patients with CD and 2.2 per 10,000 person-years in the general population (n events = 40 and 73, respectively; hazard ratio [HR] 2.68, 95% confidence interval 1.82-3.95) over a follow-up of 7.0 years. Among individuals aged >= 18, the incidence of RA was 8.4 per 10,000 person-years in CD and 5.1 per 10,000 person-years in matched comparators (n events = 110 and 322, respectively; HR 1.70, 95% confidence interval 1.36-2.12) over a follow-up of 8.8 years.DISCUSSION: Among children with CD, JIA develops nearly 3 times as often as it does in the general population, and among adults with CD, RA occurs nearly 2 times as often. Clinicians caring for patients with CD with joint symptoms should have a low threshold to evaluate for JIA or RA.

- INTRODUCTION: Risk stratification based on biochemical variables is a useful tool for monitoring ursodeoxycholic acid (UDCA)-treated patients with primary biliary cholangitis (PBC). Several UDCA response criteria and scoring systems have been proposed for risk prediction in PBC, but these have not been validated in large external cohorts. METHODS: We performed a study on data of 1746 UDCA-treated patients with PBC from 25 centers in Europe, United States, and Canada. The prognostic performance of the risk scoring systems (GLOBE and UK-PBC) and the UDCA response criteria (Barcelona, Paris I, Paris II, Rotterdam, and Toronto) were evaluated. We regarded cirrhosis-related complications (ascites, variceal bleeding, and/or hepatic encephalopathy) as clinical end points. RESULTS: A total of 171 patients reached a clinical end point during a median 7 years (range 1-16 years) of follow-up. The 5-, 10- and 15-year adverse outcome-free survivals were 95%, 85%, and 77%. The GLOBE and UK-PBC scores predicted cirrhosis-related complications better than the UDCA response criteria. The hazard ratio (HR) for a 1 standard deviation increase was HR 5.05 (95% confidence interval (CI): 4.43-5.74, P < 0.001) for the GLOBE score and HR 3.39 (95% CI: 3.10-3.72, P < 0.001) for the UK-PBC score. Overall, the GLOBE and UK-PBC risk scores showed similar and excellent prognostic performance (C-statistic, 0.93; 95% CI: 0.91%-95% vs 0.94; 95% CI: 0.91%-0.96%). DISCUSSION: In our international, multicenter PBC cohort, the GLOBE and UK-PBC risk scoring systems were good predictors of future cirrhosis-related complications.

- Background: It is becoming increasingly evident that chronic inflammation may predispose cancer development. In the stomach, inflammation caused by Helicobacter pylori infection is linked to gastric cancer. Cholecystectomy is regularly followed by duodenogastric bile reflux and reactive gastritis. To test whether a noninfectious long-standing inflammation impels gastric carcinogenesis as well, we assessed the risk of gastric cancer in a large, population-based cohort of cholecystectomized patients.Methods: We identified 251,672 individuals, in the Swedish National Inpatient Register, who had undergone cholecystectomy between 1970 and 1997. All incident cases of gastric cancer were identified through linkage to the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for comparisons with cancer rates of the general population in Sweden.Results: We found an 11% greater overall risk of distal gastric cancer (SIR=1.11, 95% CI 1.04-1.19). The risk increase was only observed among men (SIR=1.21, 95% CI 1.10-1.32), whereas no excess risk was evident for women. For men, the risk was elevated for up to 10 yr after surgery, but this elevation disappeared with longer follow-up time. There was no clear association between cholecystectomy and cardia cancer (SIR=0.95, 95% CI 0.76-1.16).Conclusions: Inconsistency over gender strata, implausibly short induction and latency time, and disappearance of the effect over time makes a causal relationship between cholecystectomy and distal gastric cancer less likely. The findings set aside concerns of harmful long-term consequences of cholecystectomy.

- Introduction: Data suggest atherosclerotic-related inflammation may play a role in the pathogenesis of inflammatory bowel disease (IBD), but large-scale studies are missing.Methods: In this nationwide case-control study, we used the Swedish Patient Register and the Epidemiology Strengthened by histoPathology Reports in Sweden cohort to identify adult cases of incident IBD between 2002 and 2021, with each case matched to up to 10 general population controls. We used conditional logistic regression to calculate odds ratios (OR) for exposure to an atherosclerotic-related condition (myocardial infarction, thromboembolic stroke, or atherosclerosis itself) before being diagnosed with IBD.Results: There were a total of 56,212 individuals with IBD and 531,014 controls. Of them, 2,334 (4.2%) cases and 18,222 (3.4%) controls had a prior diagnosis of an atherosclerotic-related condition, corresponding to an OR of 1.30 (95% confidence interval [CI] 1.24-1.37). Results were statistically significant for both Crohn's disease (OR 1.37, 95% CI 1.26-1.48) and ulcerative colitis (OR 1.27, 95% CI 1.20-1.35) and for individuals who developed IBD at 40-59 years of age and 60 years or older. In addition, associations persisted when adjusting for underlying comorbidities, including the presence of immune-mediated diseases and prior aspirin and/or statin use. The highest odds of an atherosclerotic-related condition were seen in the 6-12 months before IBD diagnosis, though odds were increased even >= 5 years before. A higher magnitude of odds was also observed when having 2 or more atherosclerotic-related conditions when compared with having only 1 condition.Discussion: A history of an atherosclerotic-related condition is associated with increased odds of developing IBD, particularly among older adults. Future studies should investigate whether drugs targeting atherosclerotic-related inflammation may prevent IBD in higher-risk individuals.

- OBJECTIVES: Corticosteroids are a cornerstone in the treatment of a severe attack of ulcerative colitis (UC). The long-term prognosis in this patient group is not well described. We studied the long-term colectomy and relapse rates in patients given intensive intravenous corticosteroid treatment (IIVT) for acute UC. METHODS: A retrospective clinical study of 158 patients with UC treated in 1975-1982 with IIVT. Patients were followed-up to death, colectomy or last visit. RESULTS: A total of 11 patients were excluded due to change of diagnosis (N = 10) or lost to follow-up (N = 1). The indication for index IIVT in the remaining 147 patients was a severe attack (N = 61), a moderately severe attack (N = 45), a mild attack (N = 29) or chronic continuous disease (N = 12). The median (range) duration of follow-up was 173 (4-271) months in patients escaping colectomy during the first 3 months. Three months after IIVT, the colectomy rates were 28/61 (46%) in a severe attack, 4/45 (9%) in a moderately severe, and 1/29 (3%) in a mild attack. After 10 yr, the colectomy rates were 39/61 (64%), 22/45 (49%), and 8/29 (28%), respectively. During follow-up, neither colectomy incidence beyond 3 months, time to first relapse nor relapse incidence was influenced by severity of initial attack, except for a lower relapse incidence after a severe attack. CONCLUSIONS: In patients escaping colectomy during the first 3 months after IIVT, the future prognosis was similar irrespective of initial disease severity.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: We aimed to assess the risk of serious infection in patients with inflammatory bowel disease (IBD) treated with vedolizumab compared with those treated with anti-tumor necrosis factors (TNF) and the general population.METHODS: In this Swedish cohort study, treatment episodes were identified from nationwide health registers. We used Cox regression with propensity score-matched cohorts to estimate hazard ratios (HRs) for incident serious infections, defined as infections requiring hospital admission.RESULTS: During 1,376 treatment episodes in Crohn's disease, the rate of serious infections per 100 person-years (PY) was 5.18 (95% CI = 3.98-6.63) with vedolizumab vs 3.54 (95% CI = 2.50-4.85) with anti-TNF; HR = 1.72 (95% CI = 1.12-2.65), partly explained by more gastrointestinal infections. Compared with the rate of 0.75/100 PY (95% CI = 0.59-0.92) in a matched general population cohort, vedolizumab demonstrated higher risk (HR = 7.00; 95% CI = 5.04-9.72). During 1,294 treatment episodes in ulcerative colitis, the corresponding rates were 3.74/100 PY (95% CI = 2.66-5.11) with vedolizumab vs 3.42/100 PY (95% CI = 2.31-4.89) with anti-TNF; HR = 0.80 (95% CI = 0.47-1.36) during the initial 1.1 years and HR = 2.03 (95% CI = 0.65-6.32) after 1.1 years (truncated due to nonproportional hazards). Pneumonia accounted for 40% of all infections among anti-TNF, whereas no case was observed among vedolizumab episodes. Compared with the rate of 0.69/100 PYs (95% CI = 0.53-0.87) in a matched general population cohort, vedolizumab showed an HR of 5.45 (95% CI = 3.67-8.11).DISCUSSION: Vedolizumab was associated with increased risks of serious infections compared with anti-TNF in Crohn's disease but not in ulcerative colitis. Nonetheless, the panorama of serious infections seemed to differ between the drugs. Our findings underscore the importance of clinical awareness of infections and the safety profile of the 2 therapies.

Oral Contraceptive Use and Risk of Ulcerative Colitis Progression : A Nationwide Study
- 2016
-
Ingår i: American Journal of Gastroenterology. - New York, USA : Nature Publishing Group. - 0002-9270 .- 1572-0241. ; 111:11, s. 1614-1620

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: Oral contraceptive (OC) use has been consistently linked to increased risk of inflammatory bowel disease. Nonetheless, a specific role of OC in the natural history of ulcerative colitis (UC) is unknown.METHODS: We identified 6,104 incident female UC cases aged 16-51 years at diagnosis from the Swedish National Patient Register starting in January of 2003. Information on current OC use was obtained from the Prescribed Drug Register starting in July of 2005. We followed cases through December of 2014 for primary outcome defined as first UC-related surgery, and the secondary outcomes defined by recipient of the first prescription of oral steroids or anti-tumor necrosis factor (anti-TNF) use. We used Cox proportional hazard modeling with time-varying covariates to estimate multivariable-adjusted hazard ratio (aHR) and 95% confidence interval (CI).RESULTS: Over 31,421 person-years of follow up, we observed 162 cases of UC-related surgery. Compared with nonusers, current and past use of OC were not significantly associated with risk of UC-related surgery (aHR= 0.79; 95% CI, 0.52-1.18; and aHR= 0.74, 95% CI, 0.46-1.18, respectively). The association did not appear to be modified by type of OC use (progestin-only vs. combination of progestin and estrogen), longer duration of use, or higher number of dispensed prescriptions (All P-trend > 0.28). Similarly, longer use or higher cumulative number of OC prescriptions were not associated with increased risk of receiving a steroid prescription (P-trend = 0.68 and 0.63, respectively). In exploratory analyses restricted to Stockholm county, current OC use was not associated with increased risk of receiving anti-TNF therapy (aHR= 0.83, 95% CI, 0.59-1.18).CONCLUSIONS: In a large nationwide registry of UC patients, we found no association between OC use and UC progression. Our data offer reassurance regarding the safety of OC assessed by its effect on risk of surgery and steroid or anti-TNF use in women with established UC.

Forskningsöversikt (refereegranskat)abstract
- OBJECTIVES: To conduct a systematic review and meta-analysis that defines the worldwide incidence of celiac disease (CD) and examines temporal trends.METHODS: MEDLINE and EMBASE were searched for population-based studies reporting the incidence of CD in the overall population, children, or adults. No limits were placed on year or language of publication. Studies solely examining at-risk populations (e.g., patients with type 1 diabetes) were excluded. Random-effects models were performed to meta-analyze sex- and age-specific incidence in the 21st century. Temporal trend analyses assessed the average annual percent change in CD incidence over time.RESULTS: Of 11,189 citations, 86 eligible studies were identified for inclusion, of which 50 were deemed suitable for analyses. In the 21st century, the pooled female incidence of CD was 17.4 (95% confidence interval [CI]: 13.7, 21.1) (I-2= 99.5%) per 100,000 person-years, compared with 7.8 (95% CI: 6.3, 9.2) (I-2= 98.6%) in males. Child-specific incidence was 21.3 per 100,000 person-years (95% CI: 15.9, 26.7) (I-2= 99.7%) compared with 12.9 (95% CI: 7.6, 18.2) (I-2= 99.9%) in adults. Pooling average annual percent changes showed the incidence of CD to be increasing by 7.5% (95% CI: 5.8, 9.3) (I-2= 79.6%) per year over the past several decades.DISCUSSION: Incidence of CD is highest in females and children. Overall, the incidence has been significantly rising in the latter half of the 20th century and into the 21st century throughout the Western world. Population-based studies in Africa, Asia, and Latin America are needed to provide a comprehensive picture of the global incidence of CD.
