- 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.

Tidskriftsartikel (refereegranskat)abstract
- A recent study in Sweden on patients with acute liver failure (ALF) 1994-2003 demonstrated that the most common causes were paracetamol toxicity (42%) and idiosyncratic drug reactions (15%). In 11% of cases of ALF no definite etiology could be established. Among patients with paracetamol toxicity, the spontaneous survival without liver transplantation was 82% compared to 49% in patients with reactions to other drugs and 29% among the patients with indeterminate cause. Patients with ALF need a rapid and effective diagnostic work-up to detect the etiology as this often determines the outcome. In ALF it is of major importance to make an early contact with a transplant centre as the search for a suitable donor organ may take time in patients who are candidates for a liver transplantation. Patients with acute liver failure need a multidisciplinary care with co-operation between hepatologists, intensive care unit specialists and transplant surgeons.

- Objectives. Cirrhosis is a well-known risk factor for hepatocellular cancer, but the true risk in autoimmune hepatitis (AIH) is scarcely studied. Other cancers may arise after prolonged use of immune-modulating drugs. The aim of this study was to investigate the cancer risk in a large cohort of AIH patients.Material and methods. Six hundred and thirty-four Swedish patients in a well-defined cohort were matched to the Cause of Death Registry and the Cancer Registry. Standard incidence ratios were calculated by relating the incidences in the cohort to an age-matched material from the Swedish background population.Results. A higher overall incidence of malignancies than the background population was found, counting from the date of diagnosis (standard incidence ratio (SIR) 2.08, 95% CI 1.68-2.55). The highest risk was found for hepatocellular carcinoma (HCC). We found 10 cases (4.0%) in 248 patients with cirrhosis, which gives an incidence rate of 0.3%. Standard incidence ratio for developing hepatobiliary cancer was 54.55 (95% CI 19.92-99.99). HCC only occurred in cirrhotic patients. There was also an increased risk for non-melanoma skin cancer (SIR 9.87, 95% CI 6.26-14.81).Conclusion. A slightly enhanced risk for malignancies in general compared to the background population was found. The risk of hepatobiliary cancer was increased, but the annual risk over the observational period was well under the postulated 1.5% when surveillance in cirrhotic patients is considered to be cost-effective.

- Introduction: Autoimmune hepatitis (AIH) is a liver disease that primarily affects women. Many become ill during childbearing age, and medication can be lifelong. Few studies exist on pregnancy outcome in women with AIH. Objectives: The aim was to assess the outcome of women with AIH and their children during pregnancy and postpartum.Materials and methods: Sixty-four women from a well-characterised cohort with AIH filled out a questionnaire with information about their disease, miscarriage/abortion, pregnancies and potential birth defects in 2012. In 2004, 106 women answered the same questionnaire and their results were analysed along with the new questionnaires. Results: One hundred and thirty-eight women have completed the questionnaire and 100 children have been born by 58 women. Fifty-seven women (41%) had cirrhosis. In 84% of the pregnancies, the AIH was stable or milder, 32% had an increase in activity postpartum. The proportion of preterm births (before week 38) was 22%, caesarean sections 17%, malformations 3%, and two children died. Twenty-three women with cirrhosis had children after diagnosis of cirrhosis but without more complications than for non-cirrhotic mothers. However, they did have a higher prevalence of caesarean sections. Conclusion: Pregnancy and childbirth in AIH appear to be safe for both child and mother, even in women with compensated liver cirrhosis.

Increased Mortality Risk in Patients With Phenotypic Hereditary Hemochromatosis But Not in Their First-Degree Relatives
- 2009

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: Hereditary hemochromatosis (HH) is an autosomal-recessive disorder characterized by iron overload. Relatives of HH patients were screened and those with HH-associated mutations and an increased iron load were identified. However, little is known about their mortality or strategies for their management. We assessed mortality among Swedish patients with HH and their first-degree relatives using health and census registers. METHODS: We performed a matched population-based cohort study of 3832 patients with HH and their 14,496 first-degree relatives using data collected from 1990 through 2007. Mortality data from these groups were compared with that of 38,969 population controls and their 143,349 first-degree relatives using Cox regression analyses. RESULTS: Patients identified on the basis of hospitalization with HH had an increased risk (relative risk [RR]) for death (RR, 2.45; 95% confidence interval [CI], 2.27-2.64; 857 deaths). Patients identified through other means had a mortality risk that was lower than those identified in the hospital but higher than controls (RR, 1.15; 95% CI, 1.00-1.33; 216 deaths). Their first-degree relatives had only a marginally increased mortality risk (RR, 1.05; 95% CI, 1.01-1.10); this RR was similar to that of patients' spouses (RR, 1.09; 95% CI, 0.86-1.38; 82 deaths). Patients with HH who also had a family history of HH did not have an increased mortality risk compared with other groups (RR, 1.05; 95% CI 0.67-1.62; 21 deaths). CONCLUSIONS: Patients with HH have a modestly increased mortality risk compared with controls. The mortality of relatives is increased marginally compared with controls, and is similar among biological and nonbiological relatives.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: Corticosteroids alone or in conjunction with azathioprine (AZA) is the standard treatment in autoimmune hepatitis (AiH). Individual variations in thiopurine (TP) metabolism may affect both drug efficacy and toxicity. Our aim was to investigate the utility of thiopurine methyltransferase (TPMT) as well as thioguanine nucleotide (TGN) and methylthioinosine monophosphate (meTIMP) metabolite measurements with regard to clinical outcome. METHODS: Two hundred thirty-eight patients with AiH were included in this cross-sectional study. TPMT status was assessed in all patients, while TGN and meTIMP were measured in patients with ongoing TP medication. Clinical outcome was evaluated by liver tests and the ability to withdraw steroids. RESULTS: TPMT genotyping (n=229) revealed 207 (90.4%) wild-type and 22 heterozygous patients. One hundred forty-three patients had ongoing TP therapy with AZA (n=134) or mercaptopurine (MP; n=9); response was judged as complete response (CR) in 113 patients and partial response (PR) in 30 patients. Both TP dose (1.64 vs 1.19mg/kg; p=0.012) and TPMT activity (14.3 vs 13.5; p=0.05) were higher in PR, resulting in similar TGN levels (PR: 121pmol/8x10(8) red blood cells [RBC]; CR: 113pmol/8x10(8) RBC; p=0.33) but higher meTIMP levels in PR (1350 vs 400pmol/8x10(8) RBC; p=0.004). Patients able to withdraw steroids or who were using 5mg prednisolone daily were treated with lower TP doses than patients on higher steroid doses (1.15 vs 1.18 vs 1.82mg/kg; p<0.001). CONCLUSIONS: TP metabolite measurements are of clinical value in AiH patients who do not respond to standard TP treatment and for the identification of a shifted metabolism, which may demand an alternative treatment strategy.

- The impact of the microenvironment on innate lymphoid cell (ILC)-mediated immunity in humans remains largely unknown. Here we used full-length Smart-seq2 single-cell RNA-sequencing to unravel tissue-specific transcriptional profiles and heterogeneity of CD127+ ILCs across four human tissues. Correlation analysis identified gene modules characterizing the migratory properties of tonsil and blood ILCs, and signatures of tissue-residency, activation and modified metabolism in colon and lung ILCs. Trajectory analysis revealed potential differentiation pathways from circulating and tissue-resident naïve ILCs to a spectrum of mature ILC subsets. In the lung we identified both CRTH2+ and CRTH2− ILC2 with lung-specific signatures, which could be recapitulated by alarmin-exposure of circulating ILC2. Finally, we describe unique TCR-V(D)J-rearrangement patterns of blood ILC1-like cells, revealing a subset of potentially immature ILCs with TCR-δ rearrangement. Our study provides a useful resource for in-depth understanding of ILC-mediated immunity in humans, with implications for disease.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The exact incidence and prevalence of Budd-Chiari syndrome (BCS) is unknown in the general population. Published reports differ in terms of the clinical characteristics, effects of therapy and survival. AIMS: To investigate the epidemiology, clinical presentation and survival in patients with BCS. METHODS: Retrospective multicentre study in Sweden reviewing the medical records of all patients with BCS 1986-2003, identified from the computerised diagnosis database of 11 hospitals, including all university hospitals and liver transplantation centres. RESULTS: Forty-three patients with BCS were identified, of whom nine (21%) had concomitant portal vein thrombosis. The mean age-standardised incidence and prevalence rates in 1990-2001 were calculated to be 0.8 per million per year and 1.4 per million inhabitants respectively. Myeloproliferative disorders (38%), thrombophilic factors (31%) and oral contraceptives (30%) were common aetiological factors. Two or more risk factors were present in 44%. In 23%, no risk factor was evident. The median follow-up time was 2.7 years. Seventy-two percent were on anticoagulant therapy during follow-up. Transjugular intrahepatic portosystemic shunting, surgical shunting procedures and liver transplantation were performed in 4, 6 and 18 patients respectively. Nineteen patients died. The overall transplantation-free survival at 1, 5 and 10 years was 47, 28 and 17% respectively. CONCLUSIONS: Budd-Chiari syndrome is a rare disorder; the mean age-standardised incidence and prevalence rates in Sweden in 1990-2001 were calculated to be 0.8 per million per year and 1.4 per million inhabitants respectively. The presence of a myeloproliferative disorder was a common aetiological factor in our cohort and about half of the patients had a multifactorial aetiology. The transplantation-free survival was poor.

High prevalence of autoantibodies to C-reactive protein in patients with chronic hepatitis C infection: association with liver fibrosis and portal inflammation
- 2012

Tidskriftsartikel (refereegranskat)abstract
- The presence of autoantibodies against C-reactive protein (anti-CRP) has been reported in association with autoimmunity and histopathology in chronic hepatitis C virus (HCV) infection. Resistin could play a role in the pathogenesis of hepatitis, although results on HCV infection are ambiguous. Here we retrospectively analyzed anti-CRP and resistin levels in the sera of 38 untreated and well-characterized HCV patients at the time of their first liver biopsy. HCV activity and general health were assessed by a physician at least yearly until follow-up ended. Anti-CRP and resistin were also measured in patients with autoimmune hepatitis (AIH) and nonalcoholic fatty liver disease (NAFLD). Anti-CRP antibodies were registered in all HCV patients, whereas only a few AIH (11%) and NAFLD (12%) sera were positive. Anti-CRP levels were related to histopathological severity and were highest in patients with cirrhosis at baseline. Resistin levels were similar in HCV, AIH, and NAFLD patients, but high levels of resistin were associated with early mortality in HCV patients. Neither anti-CRP nor resistin predicted a response to interferon-based therapy or cirrhosis development or was associated with liver-related mortality. We conclude that anti-CRP antibodies are frequently observed in chronic HCV infection and could be a useful marker of advanced fibrosis and portal inflammation.

Abdominal tenderness in ascites patients indicates spontaneous bacterial peritonitis
- 2007
-
Ingår i: European journal of internal medicine. - : Elsevier BV. - 0953-6205 .- 1879-0828. ; 18:1, s. 44-47

Tidskriftsartikel (refereegranskat)abstract
- Background: Spontaneous bacterial peritonitis (SBP), which has been reported to be present in 10-30% of patients with cirrhotic ascites, may easily be overlooked. An important aim of our study was to determine whether there are any clinical signs which, in clinical practice, may predict or exclude SBP. Methods: We studied 133 patients with cirrhotic ascites from medical units at nine Swedish university hospitals where there had been at least one diagnostic ascites tap with analysis of polymorphonuclear leukocytes in the ascites fluid. The patients had initially been questioned about background factors and physically examined according to a standardized case record form. Samples of blood, urine, and ascites were then drawn for analysis according to a structured schedule. Results: SBP could be excluded in 80% of all the cases and was confirmed in 8% of the 133 patients in the final analysis. Abdominal pain and abdominal tenderness were more common in patients with SBP (p < 0.01), but no other physical sign or laboratory test could separate SBP cases from the others. Conclusions: SBP was present in about one-tenth of the hospitalized patients with cirrhotic ascites in this cohort. Performing repeated physical examinations and paying particular attention to abdominal tenderness may be the best way to become aware of the possible development of this complication.

Tidskriftsartikel (refereegranskat)abstract
- Objective. Development of ascites in patients with liver cirrhosis is an ominous sign with a poor outcome. A liver transplantation must be considered, and it then becomes important to know if there are any factors indicating a worsened prognosis. Material and methods. We used official registers for a follow-up study of at least 5 years considering the prognosis of 155 prospectively recruited in-patients with cirrhotic ascites from medical units at nine Swedish university hospitals. All patients had undergone at least one diagnostic ascites tap, and had initially been questioned about background factors and physically examined according to a standardized case record form, followed by sampling of blood, urine, and ascites. Results. Death occurred within 1 year after inclusion in 53% of the cases, and was primarily liver-related in 70%. In a multivariable analysis, the two ordinary variables that showed the strongest correlation with risk of death were serum potassium and abdominal tenderness. All 22 patients with a serum potassium concentration of at least 4.8 mmol/L (maximum 5.8 mmol/L) died within 1 year after inclusion. Potassium concentration was related to renal function and potassium-saving drugs. Conclusion. This follow-up study of a prospectively recruited cohort of in-patients with cirrhotic ascites confirms their poor prognosis. Awareness of an elevated serum potassium value, which would reflect a threatened renal function, seems essential, because it may offer a simple way to identify cases with the worst prognosis. An area for further research should be to explore the significance of including serum potassium in prognostic models.

Tidskriftsartikel (refereegranskat)abstract
- Objective. In published studies there is a lack of data about the risks, management and how women with autoimmune hepatitis (AIH) decide on and are advised about pregnancy. The aim of this study was to investigate how women with AIH consider pregnancies, are advised and pharmacologically treated, as well as the outcome. Material and methods. A questionnaire was mailed to 128 women with AIH diagnosed during their fertile period and data from the Swedish National Birth Register was also used for matched controls. Results. There was an 83% response rate to the questionnaires. Sixty-three pregnancies were reported by 35 women. 48% did not consult their doctors before getting pregnant. More than half of the women reduced or stopped the immune suppression during pregnancy or breastfeeding. Some women were advised to abstain from pregnancy or even to have an abortion. Caesarean sections were performed more frequently in the AIH group (16% compared with 6.5% in the control group p<0.01).There were no significant differences in the number of stillborn infants or infants with malformations. However, 30% of the patients experienced flare-up after delivery. Conclusions. In general, the outcome of pregnancy in women with AIH seems to be good. Current pharmacological treatment appears to be safe, including azathioprine during pregnancy and lactation. After delivery an active preparedness to increase pharmacotherapy should be considered.

Tidskriftsartikel (refereegranskat)abstract
- Objectives. Autoimmune hepatitis (AIH) is a liver disease which, if untreated, may lead to liver cirrhosis and hepatic failure. Limited data exist regarding factors predicting the long-term outcome. The aims of this study were to investigate symptoms at presentation, prognostic features, management and treatment in relation to long-term outcome of AIH. Material and methods. A cohort of 473 Swedish patients with AIH was characterized regarding initial symptoms and signs, factors predicting death and future need for liver transplantation. Survival and causes of death were retrieved from Swedish national registers. Results. At diagnosis, fatigue was a predominant symptom (69%), 47% of the patients were jaundiced and 30% had liver cirrhosis. Another 10% developed cirrhosis during follow-up. Markedly elevated alanine aminotransferase levels at presentation were correlated with a better outcome. A high international normalized ratio (INR) at diagnosis was the only risk factor predicting a need for later liver transplantation. Histological cirrhosis, decompensation and non-response to initial treatment were all factors that correlated with a worse outcome. Overall life expectancy was generally favourable. However, most deaths were liver-related, e.g. liver failure, shock and gastrointestinal bleeding. Conclusions. Cirrhosis at diagnosis, a non-response to initial immune-suppressive treatment or elevated INR values were associated with worse outcome and a need for later liver transplantation. In contrast, an acute hepatitis-like onset with intact synthetic capacity indicated a good response to treatment and favourable long-term prognosis. Lifetime maintenance therapy is most often required.

- Objective. Autoimmune hepatitis (AIH) is a chronic liver disease, which if untreated can lead to cirrhosis and hepatic failure. The aim of the study was to investigate the incidence, prevalence, diagnostic tradition and clinical initial presentation of AIH. Material and methods. Analyses were performed in 473 patients identified as having probable or definite AIH. Results. The incidence of AIH was 0.85/100,000 (95% CI 0.69-1.01) inhabitants, which is somewhat lower than reported previously. The point prevalence amounted to 10.7/100,000 (95% CI 8.8-13.1), and 76% of the cases were females. The age-related incidence curve was bimodal but men were found to have only one incidence peak in the late teens, whereas women had a peak after menopause. AIH was presented as a spectrum of clinical settings from detected en passant to acute liver failure. Almost 30% of patients already had liver cirrhosis at diagnosis. Autoantibodies indicative of AIH type 1 were found in 79% of cases. Other concomitant autoimmune diseases were frequently found (49%). Conclusions. The incidence and prevalence figures confirm that AIH is a fairly uncommon disease in the Swedish population. Symptoms at presentation were unspecific, but almost half of the patients were jaundiced, with around 30% having liver cirrhosis. The majority of Swedish AIH patients had AIH type 1.

- Background/Aims: Autoimmune Hepatitis (AIH) is a liver disease which may lead to liver cirrhosis. Cirrhosis is a well-known risk factor for hepatocellular cancer. Lymphoma is a disease, where immune modulating drugs as well as the autoimmune disease itself may contribute to the elevated risk. The aim was to investigate the risks of malignancies in a large cohort of AIH patients. Methods: Four hundred and seventy-three patients with AIH were matched to the Swedish national cancer register as well as to the death cause register. Results: We found an overall higher risk of malignancies in the cohort of A I H patients from the date of diagnosis with a SIR of 1.51 (95% CI 1.10-2.03). SIR in the subpopulation of well defined catchment areas and complete case finding was 23.28 (95% CI 7.5-54.34) for HCC. Lymphomas were found a SIR of 13.09 (95% CI 4.22-30.56). Conclusions: There was an overall increased risk of malignancies in a cohort of AIH patients, which manly was caused by hepatobiliary cancers. However, the true risk of HCC in an AIH cirrhotic cohort has yet to be investigated. A significantly higher risk of lymphomas was also found, but no clear cut association to the use of immune modulators.

- Background and aims: Adverse events (AE) leading to discontinuation or dose-reduction of thiopurine therapy (TP) occur in 9-28% of patients with inflammatory bowel disease. 6-Thioguanine (6-TG) has been proposed as an alternative treatment in patients intolerant for azathioprine (AZA), but some concerns have been raised about drug safety. Methods: We evaluated in a prospective manner the tolerance and efficacy of 6-TG in 23 Crohns disease (CD) patients (13 men, median age 41 (19-65) years) with prior intolerance (n = 18) or resistance (It = 5) to AZA and/or 6-mercaptopurine (6-MP). In addition, eight patients had tried mycophenolate mofetil. Seventeen patients (74%) had undergone intestinal resection, often several times. Results: Patients were treated with a median daily dose of 40 mg 6-TG (range 20-60) for 259 (15-2272) days. Seven of 13 patients (54%) with active disease went into remission after 8 (4-26) weeks. Sixteen patients (70%) experienced AE that lead to discontinuation (n=10) after 85 (15-451) days or dose reduction (n=6) after 78 (10-853) days. Ten of 18 patients (56%) with prior TP-intolerance discontinued 6-TG treatment due to AE compared to none of five patients with TP-resistance (p=0.046). Of 13 patients that tolerated 6-TG, eight discontinued the drug due to therapeutic failure (n=5) or safety concerns (n=3). Eight patients (35%) continued treatment beyond 12 months. There was no significant difference in maximum thioguanine nucleotide levels between patients with AE leading to discontinuation/dose reduction and patients without AE, 652 (99-2488) vs. 551 (392-1574) pmol/8 x 10(8) RBC; p=0.80. Conclusions: In this cohort of CD patients with severe disease failing traditional thiopurine treatment, a small fraction (22%) had long-term benefit of 6-TG-treatment. 6-TG therapy seems to offer a limited therapeutic gain for patients intolerant to both AZA and 6-MP and other treatment options should be considered.

Tidskriftsartikel (refereegranskat)abstract
- Background: Leukocyte scintigraphy is a noninvasive investigation to assess inflammation. We evaluated the utility of labeled leukocytes to detect small bowel inflammation and disease complications in Crohn's disease and compared it to whole small bowel enteroscopy and laparotomy findings.Methods: Scintigraphy with technetium-99m exametazime-labeled leukocytes was prospectively performed in 48 patients with Crohn's disease a few days before laparotomy; 41 also had an intraoperative small bowel enteroscopy. The same procedures were performed in 8 control patients. Independent grading of scans was compared with the results of enteroscopy and with surgical, histopathologic, and clinical data.Results: In the 8 control patients leukocyte scan, endoscopy, and histopathology were all negative for the small bowel. In patients with Crohn's disease and small bowel inflammation seen at enteroscopy and/or laparotomy (n = 39) the scan was positive in 33. In 8 patients without macroscopic small bowel inflammation, the scan was positive for the small bowel in 3 patients; at histology, 2 of 3 had inflammation. When combining results for patients and controls, the sensitivity of leukocyte scan for macroscopically evident small bowel inflammation was 0.85, specificity 0.81, accuracy 0.84, positive predictive value 0.92, and negative predictive value 0.68. Scintigraphy detected inflammatory lesions not known before laparotomy in 16 of 47 (34%) Crohn's disease patients and showed uptake in 25 of 35 (71%) bowel strictures. It was diagnostic regarding 4 of 8 abscesses and 9 of 15 fistulas. In 6 patients (13%) lesions first demonstrated by leukocyte scintigraphy were treated during the surgery performed.Conclusions: Leukocyte scintigraphy reliably detects small bowel inflammation in Crohn's disease. It gives additional information on the presence of inflammatory lesions in a fraction of patients planned for surgery.

- Thiopurine drugs are widely used as immunomodulatory and corticosteroid-sparing agents in inflammatory bowel disease. Despite being old drugs, a renewed research and clinical interest in their application has emerged during the last decade. The application of pharmacogenetic insights and metabolic monitoring, together with treatment strategies in combination with anti-TNF-antibodies and possibilities to modulate their metabolism, has paved the way to a omoderno use of the thiopurines. These aspects are briefly overviewed herein.

Ulcerative colitis : Imaging of inflammation
- 1995
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Ulcerative colitis is a chronic inflannnatory disorder of unknown origin engaging the large bowel. Based on the need for accurate assessment of inflammation, three different non-invasive techniques, two leukocyte scintigraphy techniques and one radiological method, were evaluated in the assessment of active inflammation in altogether 131 patients with ulcerative colitis. Results were compared to those of endoscopy with biopsy, and with histopathological grading of depth of ulceration in colectomy specimens. Nine non-inflamed controls were also includedLeukoeyte scintigraphy using technetium-99m exarnetazime-labelled lenkocytes was found to reliably differ between patients with and without colonic inflammation. A good correlation existed between a simple visual scoring system of lenkocyte scans and colonic inflannnation viewed endoscopically and histologically in ulcerative colitis. In active disease, inflammation was better visualized with technetiurn-99m exametazimelabelled leukocytes than with technetium-99m anti-granulocyte antibody BW 250/183.Air enema radiology was of value in estimating severe mucosal inflammation in acute ulcerative colitis. Presence of faecal residue or a normal air enema film were associated with normal or only mildly inflamed mucosa at colonoscopy, i.e. a friable or ulcerated mucosa can be excluded. The absence of faecal residue or an abnormal finding at air enema X-ray were predictive of endoscopically inflamed mucosa. Air enema radiology underestimated the extent of inflannnation compared to endoscopy or lenkocyte scintigraphy. Air enema radiology was able to demonstrate presence of deep histopathological ulceration in the colectomy specimens from patients with an acute attack of ulcerative colitis.In conclusion, scintigraphy with technetium-99m exarnetazime-labelled lenkocytes can be applied in excluding or confirming bowel inflammation in individual patients, and, in assessing intensity and extent of ulcerative colitis. Air enema radiology should be a first-line investigation in acute colitis to assess the presence of mucosal or deeper ulceration.

Tidskriftsartikel (refereegranskat)abstract
- Background: The treatment of Crohn's disease has changed owing to the recognition of its chronicity. Medical maintenance treatment and limited resections have evolved as major concepts of management, regarded as complementary, and both aim at reducing the symptoms.Methods: We investigated the symptomatic load in Crohn's disease as reflected in a cross-sectional study of the symptom index, physicians' assessment, and the patients' perception of health. A cohort of 212 patients from the primary catchment area and 125 referred patients were studied.Results: Of catchment area patients, 83% were receiving medication, and the annual rate of abdominal surgery was 5.7%. Corresponding figures for the referred patients were 82% and 10.3%. According to the symptom index, 87% of catchment area patients were in remission or had only mild symptoms; according to the physicians' assessment, 90% were. The patients' median perception of health was 90% of perfect health according to the visual analogue scale. The figures were similar for referred patients, except that referrals were considered more diseased by the physician.Conclusion: The great majority of patients with Crohn's disease are able to live in remission or experience only mild symptoms.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To quantitatively and qualitatively evaluate the water-signal performance of the consistent intensity inhomogeneity correction (CIIC) method to correct for intensity inhomogeneitiesMETHODS: Water-fat volumes were acquired using 1.5 Tesla (T) and 3.0T symmetrically sampled 2-point Dixon three-dimensional MRI. Two datasets: (i) 10 muscle tissue regions of interest (ROIs) from 10 subjects acquired with both 1.5T and 3.0T whole-body MRI. (ii) Seven liver tissue ROIs from 36 patients imaged using 1.5T MRI at six time points after Gd-EOB-DTPA injection. The performance of CIIC was evaluated quantitatively by analyzing its impact on the dispersion and bias of the water image ROI intensities, and qualitatively using side-by-side image comparisons.RESULTS: CIIC significantly ( P1.5T≤2.3×10-4,P3.0T≤1.0×10-6) decreased the nonphysiological intensity variance while preserving the average intensity levels. The side-by-side comparisons showed improved intensity consistency ( Pint≤10-6) while not introducing artifacts ( Part=0.024) nor changed appearances ( Papp≤10-6).CONCLUSION: CIIC improves the spatiotemporal intensity consistency in regions of a homogenous tissue type.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background & Aims: The importance of genetic factors for the development of primary sclerosing cholangitis (PSC) is incompletely understood. This study assessed the risk of PSC and inflammatory bowel disease (IBD) among first-degree relatives of patients with PSC, compared with the first-degree relatives of a cohort without PSC. Methods: Subjects from the national Swedish cohort of PSC patients (n = 678) were matched for date of birth, sex, and region to up to 10 subjects without a diagnosis of PSC (n = 6347). Linkage through general population registers identified first-degree relatives of subjects in both the PSC and comparison cohorts (n = 34,092). Diagnoses among first-degree relatives were identified by using the Inpatient Register. Results: The risk of cholangitis was statistically significantly increased in offspring, siblings, and parents of the PSC patient cohort, compared with relatives of the comparison cohort, with the hazard ratios and 95% confidence intervals, 11.5 (1.6–84.4), 11.1 (3.3–37.8), and 2.3 (0.9–6.1), respectively. The hazard ratios for ulcerative colitis (UC) among first-degree relatives of all PSC patients was 3.3 (2.3–4.9) and for Crohn's disease 1.4 (0.8–2.5). The risk of UC for relatives of PSC patients without IBD was also increased, 7.4 (2.9–18.9). Conclusions: First-degree relatives of patients with PSC run an increased risk of PSC, indicating the importance of genetic factors in the etiology of PSC. First-degree relatives of PSC patients without IBD are also at an increased risk of UC, which might indicate shared genetic susceptibility factors for PSC and UC.

- Background: Inflammatory bowel disease (IBD)-associated anaemia usually responds to intravenous iron. If not, additive treatment with erythropoietin has been proposed. The objective of the present retrospective study was to evaluate the effectiveness of treatment with iron sucrose alone. Methods: Sixty-one patients with IBD and anaemia (average haemoglobin 97 g/L) were treated with iron sucrose (iron dose 1.4 ± 0.5 g). The indications for iron sucrose were poor response and/or intolerance to oral iron. Treatment response was defined as an increase in haemoglobin of ≥20 g/L or to normal haemoglobin levels (>120 g/L). Two independent investigators retrospectively assessed laboratory variables, clinical findings, and concomitant medication. Results: Two patients were transferred to other hospitals after treatment and therefore could not be evaluated. Fifty-four of the remaining 59 patients (91%) responded within 12 weeks. Sixty percent of the patients had responded within 8 weeks. Five patients had no or only a partial response to iron sucrose of which three had prolonged gastrointestinal blood losses. Eight patients with normal or elevated levels of ferritin could be considered to have anaemia of chronic disease, and all of them responded to iron sucrose. During a follow-up period of 117 ± 85 (4-291) (mean ± s (standard deviation) (range)) weeks 19 patients (32%) needed at least one second course of iron sucrose because of recurrent disease. Conclusions: Anaemia associated with IBD can be successfully treated with intravenously administered iron sucrose, provided that bowel inflammation is treated adequately and enough iron is given. Treatment with iron sucrose is safe. Follow-up of haemoglobin and iron parameters to avoid further iron deficiency anaemia is recommended.

Tidskriftsartikel (refereegranskat)abstract
- Resistin is a cysteine-rich protein, which is abundantly expressed at the site of inflammation, and acts as a regulator of the NF-kB-dependent cytokine cascade. The aim of this study was to evaluate resistin levels in relation to inflammatory mediators, disease phenotype and autoantibody status in a spectrum of pathological conditions of the gastrointestinal tract. Resistin levels were measured with an ELISA in sera originated from 227 patients and 40 healthy controls (HC). Fifty patients diagnosed with non-alcoholic fatty liver disease (NAFLD), 53 ulcerative colitis (UC), 51 Crohns disease (CD), 46 autoimmune hepatitis (AIH) and 27 primary sclerosing cholangitis (PSC) were included. The sera were analysed with respect to biochemical parameters of systemic inflammation and liver function and to the presence of antibodies to nuclear antigens (ANA), mitochondria (AMA) and smooth muscle (SMA). Compared with HC, resistin levels were raised in AIH (P = 0.017) and PSC (P = 0.03); compared with NAFLD, levels were elevated in CD (P = 0.041), AIH (P andlt; 0.001) and PSC (P andlt; 0.001). Patients with elevated levels of resistin were more often treated with corticosteroids, but no difference was found between active disease and clinical remission. Resistin levels were significantly higher in ANA-positive individuals compared with ANA-negative (P = 0.025). Resistin levels were directly correlated with IL-6 (r = 0.30, P = 0.02) and IL-8 (r = 0.51, P andlt; 0.001). Elevated levels of resistin were prominent in patients with hepatobiliary inflammation and were associated with breach of self-tolerance, i.e. ANA positivity. Thus, we propose that resistin may be an important marker of disease severity in autoantibody-mediated gastrointestinal inflammatory diseases.

- Background: The EpiCom-study investigates a possible East-West-gradient in Europe in the incidence of IBD and the association with environmental factors. A secured web-based database is used to facilitate and centralize data registration. Aim: To construct and validate a web-based inception cohort database available in both English and Russian language. Method: The EpiCom database has been constructed in collaboration with all 34 participating centers. The database was translated into Russian using forward translation, patient questionnaires were translated by simplified forward-backward translation. Data insertion implies fulfillment of international diagnostic criteria, disease activity, medical therapy, quality of life, work productivity and activity impairment, outcome of pregnancy, surgery, cancer and death. Data is secured by the WinLog3 System, developed in cooperation with the Danish Data Protection Agency. Validation of the database has been performed in two consecutive rounds, each followed by corrections in accordance with comments. Results: The EpiCom database fulfills the requirements of the participating countries local data security agencies by being stored at a single location. The database was found overall to be "good" or "very good" by 81% of the participants after the second validation round and the general applicability of the database was evaluated as "good" or "very good" by 77%. In the inclusion period January 1st -December 31st 2010 1336 IBD patients have been included in the database. Conclusion: A user-friendly, tailor-made and secure web-based inception cohort database has been successfully constructed, facilitating remote data input.

- BACKGROUND: No direct comparison of health care cost in patients with inflammatory bowel disease across the European continent exists. The aim of this study was to assess the costs of investigations and treatment for diagnostics and during the first year after diagnosis in Europe.METHODS: The EpiCom cohort is a prospective population-based inception cohort of unselected inflammatory bowel disease patients from 31 Western and Eastern European centers. Patients were followed every third month from diagnosis, and clinical data regarding treatment and investigations were collected. Costs were calculated in euros (&OV0556;) using the Danish Health Costs Register.RESULTS: One thousand three hundred sixty-seven patients were followed, 710 with ulcerative colitis, 509 with Crohn's disease, and 148 with inflammatory bowel disease unclassified. Total expenditure for the cohort was &OV0556;5,408,174 (investigations: &OV0556;2,042,990 [38%], surgery: &OV0556;1,427,648 [26%], biologicals: &OV0556;781,089 [14%], and standard treatment: &OV0556;1,156,520 [22%)]). Mean crude expenditure per patient in Western Europe (Eastern Europe) with Crohn's disease: investigations &OV0556;1803 (&OV0556;2160) (P = 0.44), surgery &OV0556;11,489 (&OV0556;13,973) (P = 0.14), standard treatment &OV0556;1027 (&OV0556;824) (P = 0.51), and biologicals &OV0556;7376 (&OV0556;8307) (P = 0.31). Mean crude expenditure per patient in Western Europe (Eastern Europe) with ulcerative colitis: investigations &OV0556;1189 (&OV0556;1518) (P < 0.01), surgery &OV0556;18,414 (&OV0556;12,395) (P = 0.18), standard treatment &OV0556;896 (&OV0556;798) (P < 0.05), and biologicals &OV0556;5681 (&OV0556;72) (P = 0.51).CONCLUSIONS: In this population-based unselected cohort, costs during the first year of disease were mainly incurred by investigative procedures and surgeries. However, biologicals accounted for >15% of costs. Long-term follow-up of the cohort is needed to assess the cost-effectiveness of biological agents.

- Objective The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East–West gradient in the incidence of IBD in Europe exists.Design A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience.Results 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100 000 in 2010 for CD were 6.5 (range 0–10.7) in Western European centres and 3.1 (range 0.4–11.5) in Eastern European centres, for UC 10.8 (range 2.9–31.5) and 4.1 (range 2.4–10.3), respectively, and for IBDU 1.9 (range 0–39.4) and 0 (range 0–1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy.Conclusions An East–West gradient in IBD incidence exists in Europe. Among this inception cohort—including indolent and aggressive cases—international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

- Background:The EpiCom cohort is a prospective, population-based, inception cohort of inflammatory bowel disease (IBD) patients from 31 European centers covering a background population of 10.1 million. The aim of this study was to assess the 1-year outcome in the EpiCom cohort.Methods:Patients were followed-up every third month during the first 12 (3) months, and clinical data, demographics, disease activity, medical therapy, surgery, cancers, and deaths were collected and entered in a Web-based database (www.epicom-ecco.eu).Results:In total, 1367 patients were included in the 1-year follow-up. In western Europe, 65 Crohn's disease (CD) (16%), 20 ulcerative colitis (UC) (4%), and 4 IBD unclassified (4%) patients underwent surgery, and in eastern Europe, 12 CD (12%) and 2 UC (1%) patients underwent surgery. Eighty-one CD (20%), 80 UC (14%), and 13 (9%) IBD unclassified patients were hospitalized in western Europe compared with 17 CD (16%) and 12 UC (8%) patients in eastern Europe. The cumulative probability of receiving immunomodulators was 57% for CD in western (median time to treatment 2 months) and 44% (1 month) in eastern Europe, and 21% (5 months) and 5% (6 months) for biological therapy, respectively. For UC patients, the cumulative probability was 22% (4 months) and 15% (3 months) for immunomodulators and 6% (3 months) and 1% (12 months) for biological therapy, respectively in the western and eastern Europe.Discussion:In this cohort, immunological therapy was initiated within the first months of disease. Surgery and hospitalization rates did not differ between patients from eastern and western Europe, although more western European patients received biological agents and were comparable to previous population-based inception cohorts.

- Background and aims: Anaemia is an important complication of inflammatory bowel disease (IBD). The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis in a European prospective population-based inception cohort.Methods: Newly diagnosed IBD patients were included and followed prospectively for one year in 29 European and 1 Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization.Results: A total of 1,871 patients (CD: 686, 88%; UC: 1,021, 87%; IBDU 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and overall, 49% of CD and 39% of UC patients had at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed.Conclusions: Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

- Background: In recent years there have been increasing evidence associating liver disease with hypercoagulability, rather than bleeding.Aims: To evaluate the haemostatic potential in patients with liver disease.Methods: We measured thrombin generation in the presence and absence of thrombomodulin in patients with portal vein thrombosis (PVT, n=47), Budd-Chiari syndrome (BCS, n=15) and cirrhosis (n=24) and compared the results to those obtained from healthy controls (n=21). Fifteen patients with PVT and 10 patients with BCS were treated with warfarin and were compared with an equal number of patients with atrial fibrillation matched for prothrombin time-international normalized ratio. We assessed resistance to thrombomodulin by using ratios [marker measured in the presence]/[marker measured in the absence of thrombomodulin].Results: There were no differences between patients with BCS, patients on warfarin treatment and controls. Cirrhotic patients generated more thrombin in the presence of thrombomodulin and exhibited thrombomodulin resistance compared with controls [p=0.006 for endogenous thrombin potential (ETP) and p<0.001 for peak thrombin. P<0.001 for both ratios ETP and peak] and patients with non-cirrhotic PVT (p=0.001, p=0.006, p<0.001, p<0.001 for ETP, peak, ratio ETP, ratio peak). The patients with cirrhotic PVT exhibited higher ETP (p=0.044) and peak (p=0.02) in the presence of thrombomodulin than controls, as well as thrombomodulin resistance (ETP ratio: p=0.001, peak ratio: p=0.001).Conclusions: Hypercoagulability and thrombomodulin resistance in patients with cirrhosis were independent of the presence of splanchnic vein thrombosis. The hypercoagulability in patients with cirrhotic PVT could have implications for considering longer treatment with anticoagulants in this group.
