Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: The two main forms of inflammatory bowel disease (IBD) are Crohn’s disease and ulcerative colitis. These are chronic inflammatory disorders, mainly affecting the gastrointestinal tract.Aims: The overall aims of this thesis were to study the epidemiology of ulcerative colitis in Örebro, Sweden; to examine certain aspects of anaemia in IBD; and to determine the clinical effectiveness of medical treatments.Material and methods: Cohort studies with the sampling frame defined by the geographic boundaries of the primary catchment area of Örebro University Hospital (Papers I‒III), or by the entire IBD population in Sweden registered in the Swedish national quality registry for IBD (SWIBREG; paper IV), were performed to determine the epidemiology of ulcerative colitis, the incidence and prevalence of anaemia in IBD, and the clinical effectiveness of thiopurine drugs and vedolizumab in routine care.Results: A fivefold increase in the incidence and a tenfold increase in the prevalence of ulcerative colitis was observed in Örebro during the past 50 years. In parallel, the prognosis, in terms of risk for colectomy within 10 years from diagnosis, improved during the same time period. Earlier and more widespread use of thiopurine drugs may have contributed to the decrease in colectomies. Anaemia is common in IBD, particularly in Crohn’s disease. Vedolizumab, a new drug targeting leucocyte migration to the gut, appears to be well tolerated and effective in Swedish real-world IBD care.Conclusion: Ulcerative colitis is on the rise, and data from Örebro indicate that the number of IBD patients in Sweden already exceeds 70,000. Improved knowledge of long-term outcomes of medical therapy may have far-reaching implications for future IBD management.

- OBJECTIVE: Thiopurines are used as maintenance therapy in ulcerative colitis (UC), but whether these drugs influence the natural history of the disease is unknown. We aimed to assess the effect of thiopurines in terms of colectomy, hospital admission, progression in disease extent and anti-tumour necrosis factor (TNF) therapy within 10 years from initiation.DESIGN: Patients diagnosed with UC within the Örebro University Hospital catchment area, during 1963-2010, who initiated thiopurines (n=253) were included. To overcome the risk of confounding by indication, we compared patients who stopped treatment within 12 months because of an adverse reaction (n=76) with patients who continued therapy or discontinued due to other reasons (n=177) and assessed long-term outcomes using Cox regression with adjustment for potential confounding factors.RESULTS: The cumulative probability of colectomy within 10 years was 19.5% in tolerant patients compared with 29.0% in intolerant (adjusted HR 0.49; 95% CI 0.21 to 0.73). The probability of hospital admission was 34.0% in tolerant versus 56.2% in intolerant patients (adjusted HR 0.36; 95% CI 0.23 to 0.56). The risk for progression in disease extent was 20.4% in tolerant patients compared with 48.8% in intolerant (adjusted HR 0.47; 95% CI 0.21 to 1.06). Within 10 years, 16.1% of tolerant and 27.5% of intolerant patients received anti-TNF therapy (adjusted HR 0.49; 95% CI 0.26 to 0.92).CONCLUSION: Based on the novel approach of comparing patients tolerant and intolerant to thiopurines, we reveal that thiopurines have a profound beneficial impact of the natural history and long-term colectomy rates of UC.

- BACKGROUND: The incidence and short-term outcome of anaemia in inflammatory bowel disease (IBD) are largely unknown.AIM: To determine the incidence, prevalence and clinical outcome of anaemia in terms of resolution of anaemia within 12 months. We also planned to assess risk factors for anaemia in IBD.METHODS: A random sample of 342 patients was obtained from the population-based IBD cohort of Örebro University Hospital, Sweden, consisting of 1405 patients diagnosed between 1963 and 2010. Haemoglobin measurements recorded from 1 January 2011 to 31 December 2013 were extracted from the Clinical Chemistry data system.RESULTS: In Crohn's disease, the incidence rate of anaemia was 19.3 (95% CI: 15.4-23.7) per 100 person-years and the prevalence was 28.7% (CI: 22.0-36.2), compared with 12.9 (CI: 9.8-16.5) and 16.5% (CI: 11.2-22.9) for ulcerative colitis. Crohn's disease was associated with an increased incidence (OR = 1.60; CI: 1.02-2.51) and prevalence of anaemia (OR = 2.04; CI: 1.20-3.46) compared to ulcerative colitis. Stricturing disease phenotype in Crohn's disease (HR = 2.59; CI: 1.00-6.79) and extensive disease in ulcerative colitis (HR = 2.40; CI: 1.10-5.36) were associated with an increased risk of anaemia. Despite a higher probability of receiving specific therapy within 3 months from the diagnosis of anaemia, Crohn's disease patients had a worse outcome in terms of resolution of anaemia within 12 months (56% vs 75%; P = 0.03).CONCLUSIONS: Anaemia is a common manifestation of IBD even beyond the first years after the diagnosis of IBD. Crohn's disease is associated with both an increased risk and a worse outcome.

- Purpose: To study risk factors for uncontrolled asthma and insufficient quality of life (QoL) in patients with mild asthma, ie those without preventer treatment.Patients and Methods: Patients aged 18-75 years with a doctor's diagnosis of asthma randomly selected from primary and secondary care in Sweden. Mild asthma was defined as self-reported current asthma and no preventer treatment. Data were collected from self-completed questionnaires in 2012 and 2015. Well-controlled asthma was defined as Asthma Control Test (ACT) >20 points and no exacerbation and uncontrolled asthma as ACT<20 points and/or at least one exacerbation in the previous six months. QoL was measured by the Mini Asthma Quality of Life Questionnaire (Mini-AQLQ), where a total mean score of > 6 indicated sufficient and < 6 insufficient QoL. Multivariate logistic regression analyses were performed using asthma control and Mini-AQLQ as dependent variables. Asthma control was dichotomized as controlled and uncontrolled asthma and the Mini-AQLQ as sufficient QoL (mean score >6) and insufficient QoL (mean score <6).Results: Among 298 patients, 26% had uncontrolled asthma, 40% insufficient QoL and 20% both uncontrolled asthma and insufficient QoL. Age >60 years, obesity, daily smoking, rhinitis and inadequate knowledge of asthma self-management were independently associated with poor asthma control. Factors independently associated with insufficient QoL were age >60 years, overweight, obesity, rhinitis, sinusitis and inadequate knowledge of asthma self-management. Age >60 years, obesity, rhinitis and inadequate knowledge of asthma self-management were independently associated with both uncontrolled asthma and insufficient QoL.Conclusion: Among asthma patients without preventer medication, 26% had uncontrolled asthma and 40% had insufficient asthmarelated QoL. Older age, obesity, and rhinitis were risk factors for both poor asthma control and a reduced QoL, but having good knowledge of asthma self-management reduced this risk. Our findings suggest that this group of patients requires further attention and follow-up.

Tidskriftsartikel (refereegranskat)abstract
- Background The optimal criteria to diagnose gestational diabetes mellitus (GDM) remain contested. The Swedish National Board of Health introduced the 2013 WHO criteria in 2015 as a recommendation for initiation of treatment for hyperglycaemia during pregnancy. With variation in GDM screening and diagnostic practice across the country, it was agreed that the shift to new guidelines should be in a scientific and structured way. The aim of the Changing Diagnostic Criteria for Gestational Diabetes (CDC4G) in Sweden () is to evaluate the clinical and health economic impacts of changing diagnostic criteria for GDM in Sweden and to create a prospective cohort to compare the many long-term outcomes in mother and baby under the old and new diagnostic approaches. Methods This is a stepped wedge cluster randomised controlled trial, comparing pregnancy outcomes before and after the switch in GDM criteria across 11 centres in a randomised manner. The trial includes all pregnant women screened for GDM across the participating centres during January-December 2018, approximately two thirds of all pregnancies in Sweden in a year. Women with pre-existing diabetes will be excluded. Data will be collected through the national Swedish Pregnancy register and for follow up studies other health registers will be included. Discussion The stepped wedge RCT was chosen to be the best study design for evaluating the shift from old to new diagnostic criteria of GDM in Sweden. The national quality registers provide data on the whole pregnant population and gives a possibility for follow up studies of both mother and child. The health economic analysis from the study will give a solid evidence base for future changes in order to improve immediate pregnancy, as well as long term, outcomes for mother and child.

- Objective: To identify if gestational diabetes mellitus (GDM) is a clinically useful marker of future cardiovascular disease (CVD) risk and if GDM combined with other risks (smoking, hypertension or body mass) identifies high-risk groups.Design: Population-based matched case-control study.Setting: National Swedish register data from 1991 to 2008.Population: A total of 2639 women with a cardiovascular event and matched controls.Methods: Conditional logistic regression examined associations with CVD before and after adjustment for conventional risk factors and confounders. Effect modification for the association of GDM with CVD by body mass index (BMI), smoking and chronic hypertension was assessed by stratification and interaction testing. Adjustment for diabetes post-pregnancy evaluated its mediating role.Main outcome measures: Inpatient diagnoses or causes of death identifying ischemic heart disease, ischemic stroke, atherosclerosis or peripheral vascular disease.Results: The adjusted odds ratios (and 95% confidence intervals) for the association of CVD with GDM are 1.51 (1.07-2.14), 2.23 (2.01-2.48) for smoking, 1.98 (1.71-2.29) for obesity and 5.10 (3.18-8.18) for chronic hypertension. In stratified analysis the association of CVD with GDM was only seen among women with BMI 25, with an odds ratio of 2.39 (1.39-4.10), but only women with a BMI <30 accounted for this increased risk. Adjustment for post-pregnancy diabetes attenuated it somewhat to 1.99 (1.13-3.52).Conclusions: In the absence of other recognised cardiovascular risk factors, such as smoking, obesity or chronic hypertension, GDM is a useful marker of raised CVD risk among women with BMI between 25 and 29.
