- OBJECTIVE: To explore the relative importance of risk factors, treatments and blood counts for the occurrence of vascular complications and their impact on life expectancy in Essential Thrombocythemia (ET) and Polycythemia Vera (PV).METHODS: Nested case-control study within the Swedish MPN registry. From a cohort of 922 ET patients and 763 PV patients, 71 ET and 81 PV cases with vascular complications were compared to matched controls.RESULTS: Incidence of vascular complications were 2.0 and 3.4 events per 100 patient-years in ET and PV, respectively. At diagnosis, no significant risk factor differences were observed between cases and controls in neither of the diseases. At the time of vascular event, ET complication cases did not differ significantly from controls but in PV, cases had significantly higher WBCs and were to a lesser extent treated with antithrombotic and cytoreductive therapy. Life expectancy was significantly decreased in both ET and PV cases compared to controls.CONCLUSIONS: The risk of vascular complications is high in both ET and PV and these complications have a considerable impact on life expectancy. The protective effect of antithrombotic and cytoreductive therapy for vascular complications in PV underscores the importance of avoiding undertreatment.

- Objective. The information concerning the morbidity and mortality of hereditary hemochromatosis is based primarily on clinical cohorts of symptomatic patients. The major aim of this study was to analyze the long-term prognosis for Swedish patients with this condition, with respect to both clinical features and survival, in relation to the route by which the disease was detected. Patients and methods. 373 patients with hemochromatosis detected through routine health checkups (n = 153), family screening (n = 44), symptoms of arthralgia (n = 23), investigation of other diseases/symptoms (n = 108) or signs of liver disease (n = 45) were monitored for a mean period of 11.9 +/- 5.8 years. The degree of liver fibrosis and survival were analyzed. Results. Overall survival among these patients was not significantly different from that of a matched normal population. The patients diagnosed through health check-ups and family screening were detected at an earlier age and had the highest rate of survival. Liver biopsy at the time of diagnosis revealed cirrhosis in 9% of those detected through the health check-ups and 5% in the case of family screening, compared with 13% for the group with arthralgia, 17% for other diseases/symptoms and 42% for liver disease. Conclusion. Health check-ups and family screening allow detection of hereditary hemochromatosis at an earlier age and with less advanced liver fibrosis, although a few of these patients have already developed cirrhosis. Our study indicates that iron indices should be included in health check-ups, and if abnormal, should lead to further investigation.

- Patienter med svårt skov av ulcerös kolit bör vårdas på sjukhus och handläggas av gastroenterolog och kolorektal kirurg i nära samarbete.Skovets svårighetsgrad kan underskattas, varför noggrann bedömning av inflammationens utbredning och svårighetsgrad enligt validerade kriterier är viktigt.Intravenös behandling med kortikosteroider är en av hörnstenarna i den akuta behandlingen.Patienter som inte förbättras på denna behandling, bör erbjudas medicinsk »rescue-behandling« eller kolektomi.Infliximab har visats vara en effektiv rescue-behandling och kan minska behovet av kolektomi inom de första 3 månaderna och upp till 3 år.

- Background: Continuous positive airway pressure (CPAP) has been shown to improve oxygenation and a number of different CPAP systems are available. The aim of this study was to assess lung volume and ventilation distribution using three different CPAP techniques. Methods: A high-flow CPAP system (HF-CPAP), an ejector-driven system (E-CPAP) and CPAP using a Servo 300 ventilator (V-CPAP) were randomly applied at 0, 5 and 10 cmH2O in 14 volunteers. End-expiratory lung volume (EELV) was measured by N2 dilution at baseline; changes in EELV and tidal volume distribution were assessed by electric impedance tomography. Results: Higher end-expiratory and mean airway pressures were found using the E-CPAP vs. the HF-CPAP and the V-CPAP system (P<0.01). EELV increased markedly from baseline, 0 cmH2O, with increased CPAP levels: 1110±380, 1620±520 and 1130±350 ml for HF-, E- and V-CPAP, respectively, at 10 cmH2O. A larger fraction of the increase in EELV occurred for all systems in ventral compared with dorsal regions (P<0.01). In contrast, tidal ventilation was increasingly directed toward dorsal regions with increasing CPAP levels (P<0.01). The increase in EELV as well as the tidal volume redistribution were more pronounced with the E-CPAP system as compared with both the HF-CPAP and the V-CPAP systems (P<0.05) at 10 cmH2O. Conclusion: EELV increased more in ventral regions with increasing CPAP levels, independent of systems, leading to a redistribution of tidal ventilation toward dorsal regions. Different CPAP systems resulted in different airway pressure profiles, which may result in different lung volume expansion and tidal volume distribution.

- Objective: Randomized controlled trials have shown the effectiveness of Adalimumab in ulcerative colitis. However, real-life data is scarce. We aimed to assess the effectiveness and predictive factors of effectiveness in a large Swedish cohort. Methods: Retrospective capture of data from local registries at five Swedish IBD centers. Clinical response and remission rates were assessed at three months after starting adalimumab treatment and patients were followed until colectomy or need for another biological. Bio-naive patients were compared to bio experienced patients. Factors associated with short term responses were assessed using logistic regression model. Failure on drug was assessed using a Cox proportional hazards regression model. Results: 118 patients (59 males, 59 females) with median age 34.4 years (IQR 27.0–51.4) were included. Median disease duration was 4.3 years (IQR 2.0–9.0) and follow-up 1.27 years (IQR 0.33–4.1). A clinical corticosteroid-free remission was achieved by 38/118 (32.2%) and response by 91/118 (77%) after three months. CRP >3 mg/l at baseline was predictive of short-term failure to reach corticosteroid-free remission. Factors associated with survival on the drug were male gender, CRP <3 mg/l and absence of primary sclerosing cholangitis. Patients >42 years of age at diagnosis were more likely to respond to adalimumab and remain on treatment compared to patients <20 years. Conclusions: An elevated CRP-level, primary sclerosing cholangitis and female gender were predictors of treatment failure. In contrast older age at diagnosis was a predictor of short-term clinical response and drug survival. Prior infliximab failure, regardless of cause, did not influence the outcome of adalimumab treatment.

- Fluorescent probes identifying protein aggregates are of great interest, as deposition of aggregated proteins is associated with many devastating diseases. Here, we report that a fluorescent amyloid ligand composed of two distinct molecular moieties, an amyloidophilic pentameric oligothiophene and a porphyrin, can be utilized for spectral and lifetime imaging assessment of recombinant A 1-42 amyloid fibrils and A deposits in brain tissue sections from a transgenic mouse model with Alzheimers disease pathology. The enhanced spectral range and distinct lifetime diversity of this novel oligothiopheneporphyrin-based ligand allow a more precise assessment of heterogeneous amyloid morphology compared with the corresponding oligothiophene dye.

- Background similar to Patients with inflammatory bowel disease (IBD) often complain of fatigue. Aim similar to To investigate the prevalence and characteristics of fatigue among IBD out-patients in Scandinavia and to provide normative values for fatigue in IBD patients. Methods similar to A cross-sectional study was conducted on 425 IBD patients from six out-patient centres in Denmark, Norway and Sweden. Fatigue was measured using the Multidimensional Fatigue Inventory. The patients were also screened for anaemia and iron deficiency. Each centre included approximately 5% of their IBD cohort. The patients were enrolled consecutively from the out-patient clinics, regardless of disease activity and whether the visit was scheduled. The fatigue analysis was stratified for age and gender. Results similar to Using the 95th percentile of the score of the general population as a cut-off, approximately 44% of the patients were fatigued. When comparing the IBD patients with disease activity to the IBD patients in remission, all dimensions of fatigue were statistically significant (P less than 0.05). Being anaemic or iron deficient was not associated with increased fatigue. Being a male patient with ulcerative colitis treated with corticosteroids was a strong determinant for increased fatigue. The normative ranges for IBD fatigue were calculated. Conclusions similar to Fatigue in IBD is common regardless of anaemia or iron deficiency. Fatigue in IBD is most marked for patients less than60 years of age. Stratifying for gender and age is necessary when analysing fatigue, as fatigue is expressed differently between groups.

- Objective. The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. Materials and methods. This longitudinal follow-up study included 300 IBD outpatients from six centers in Scandinavia. Patients were enrolled in a research cohort, in which each center included 5% of their IBD cohort. The study was prospectively planned, while data were retrospectively collected. The burden of anemia was calculated as number of months with anemia. A Markov model was used to calculate the probabilities of transitioning between stages. The European guidelines were used as the standard for anemia management. Results. Anemia affected andgt; 50% of IBD outpatients during the 2-year observation period. Totally, 20% of the total observation time was spent in anemia. Over the 7200 months of observation, anemia was found in 1410 months. The most frequent type was combined anemia (63%). Combined anemia covers both anemia of chronic disease (ACD) and iron-deficiency anemia (IDA). Pure ACD was present in 21% of burden time, while pure IDA was present in 16% of burden time. The European guidelines have mainly been implemented. Conclusion. Anemia affected a majority of the IBD outpatients. One in five months, the patients were anemic. Anemia related to inflammation dominated the different types of anemia. Pure IDA was found in for 16%. These findings, despite a fair implementation of guidelines.

- Objective. To evaluate the prevalence of anemia and iron deficiency (ID) among patients with inflammatory bowel disease (IBD) in the Scandinavian countries. Material and methods. A cross-sectional study including 429 IBD patients from six centers in Denmark, Norway and Sweden. Patients were screened for anemia and ID. Each center included similar to 5% of their IBD cohort. Patients were consecutively seen in the outpatient clinic, regardless of disease activity and whether the visits were scheduled or not. Results. The overall prevalence of anemia was 19% (95% CI: 16--23%). The prevalence was higher among patients with Crohns disease than among patients with ulcerative colitis (p = 0.01). The etiology of anemia was as follows: iron deficiency anemia (20%), anemia of chronic disease (12%), and both conditions (68%). Less than 5% had folate acid or vitamin B12 deficiency. ID was found in 35% (CI: 31-40%) of the patients. Conclusions. Anemia was present in every fifth IBD patient and ID in every third IBD patient.
