- Objective. Patients with inflammatory bowel disease (IBD) often have low iron stores or anaemia. There is controversy about whether iron should be supplemented orally or intravenously (i.v.). The purpose of this study was to investigate whether treatment with intravenous iron is superior to treatment with oral iron. The primary end-points were response and remaining anaemia at the end of treatment (EOT).Material and methods. Ninety-one patients with IBD and anaemia (B-Hb <115 g/L) were randomized to oral iron sulphate (n=46) or intravenous iron sucrose (n=45) treatment for 20 weeks.Results. Forty-three patients in the intravenous iron group completed the study compared to 35 patients in the oral iron group (p=0.0009). Only 22 patients (48%) tolerated the prescribed oral dose, and 52% reduced the dose or withdrew from treatment because of poor tolerance. At EOT, 47% patients in the oral iron group increased their B-Hb by ≥20 g/L, compared with 66% in the intravenous iron group (p=0.07). In the oral iron group, 41% still had anaemia versus 16% of the patients in the intravenous iron group (p=0.007), and 22% versus 42% reached their reference B-Hb level (p=0.04). Treatment with intravenous iron sucrose improved iron stores faster and more effectively than oral iron (p=0.002). Under treatment with intravenous iron, 74% of the patients had no anaemia and normal S-ferritin levels (>25 µg/L) at EOT compared with 48% of patients receiving oral iron (p=0.013).Conclusions. Treatment with intravenous iron sucrose is effective, safe, well tolerated and superior to oral iron in correcting haemoglobin and iron stores in patients with IBD.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The cause and pathophysiology of ulcerative colitis are both mainly unknown. We have previously used whole-genome microarray technique on biopsies obtained from patients with ulcerative colitis to identify 5 changed mucosal transcripts. The aim of this study was to compare mucosal expressions of these five transcripts in ulcerative colitis patients vs. controls, along with the transcript expression in relation to the clinical ulcerative colitis status. METHODS: Colonic mucosal specimens from rectum and caecum were taken at ambulatory colonoscopy from ulcerative colitis patients (n = 49) with defined inflammatory activity and disease extension, and from controls (n = 67) without inflammatory bowel disease. The five mucosal transcripts aldolase B, elafin, MST-1, simNIPhom and SLC6A14 were analyzed using quantitative real-time PCR. RESULTS: Significant transcript differences in the rectal mucosa for all five transcripts were demonstrated in ulcerative colitis patients compared to controls. The grade of transcript expression was related to the clinical disease activity. CONCLUSION: The five gene transcripts were changed in patients with ulcerative colitis, and were related to the disease activity. The known biological function of some of the transcripts may contribute to the inflammatory features and indicate a possible role of microbes in ulcerative colitis. The findings may also contribute to our pathophysiological understanding of ulcerative colitis.

- Circulating proteins are vital in human health and disease and are frequently used as biomarkers for clinical decision-making or as targets for pharmacological intervention. Here, we map and replicate protein quantitative trait loci (pQTL) for 90 cardiovascular proteins in over 30,000 individuals, resulting in 451 pQTLs for 85 proteins. For each protein, we further perform pathway mapping to obtain trans-pQTL gene and regulatory designations. We substantiate these regulatory findings with orthogonal evidence for trans-pQTLs using mouse knockdown experiments (ABCA1 and TRIB1) and clinical trial results (chemokine receptors CCR2 and CCR5), with consistent regulation. Finally, we evaluate known drug targets, and suggest new target candidates or repositioning opportunities using Mendelian randomization. This identifies 11 proteins with causal evidence of involvement in human disease that have not previously been targeted, including EGF, IL-16, PAPPA, SPON1, F3, ADM, CASP-8, CHI3L1, CXCL16, GDF15 and MMP-12. Taken together, these findings demonstrate the utility of large-scale mapping of the genetics of the proteome and provide a resource for future precision studies of circulating proteins in human health.

- Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ∼2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

- Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

- Det råder på sina håll en oro och ett mörker i debatten och föreställningarna om samhällets tillstånd. Bilder målas av en värld av kollapsande system och spruckna fasader, där de folkvalda fattar beslut som utarmar människors trygghet och livsvillkor. Det talas om det förljugna etablissemanget, om politisk korrekthet som ödelägger och förstör. Andra ser hur antidemokratiska krafter, likt början av förra seklet, växer sig större och tar allt mer plats på gator och torg. Somliga beskriver en demokrati i kris, om obönhörligt växande sprickbildningar i samhällsbygget. Och i spåren av dessa skeenden berättas hur otrygghetens och rädslans landskap breder ut sig. Världen som vi en gång kände den tycks långsamt glida ur våra händer. Den välputsade fasaden spricker. Samtidigt finns indikationer på att beskrivningen av samhällets förestående krackelering har chimäriska drag, en illusion framvuxen i en tid då det som tidigare varit etablerade normer och ideal på olika sätt utmanas och ifrågasätts. Kanhända är det så att samhällets palett skiftar i långt fler nyanser än mörkaste grått? Kanhända spirar det mitt ibland oss en värld fylld av möjligheter och förutsättningar för människor att leva, bo och utvecklas – tillsammans och sida vid sida? För i konstrast till bilden av samhällets rämnande grundvalar, kan skymtas skriftningar i den gemensamma värdegrunden i riktning mot ökad tolerans, öppenhet och jämlikhet. Kanske är dessa skiftningar tecken på att det förekommer en hel del sprickor också i föreställningen om den spruckna fasaden? Sprickor i fasaden är den sjuttioandra forskarantologin från SOM-institutet vid Göteborgs universitet. Titeln refererar till den sprickbildning i samhällsbygget som på olika håll har lyfts fram i den allmänna debatten. En del av de frågor som analyseras i boken påvisar också tydliga sprickor och polariseringstendenser – inte sällan i frågor som sträcker sig bortom den klassiska vänsterhögerdimensionen. Det är inte längre bara frågor som rör skatter, välfärdsstatens finansiering eller förhållandet mellan offentligt och privat som står för den största sprickbildningen. I många fall handlar det också om sociala och kulturella frågor som skapar skiljelinjer i befolkningen.

- The association between use of statins, renin-angiotensin system (RAS) inhibitors and/or β-blockers and long-term mortality in patients with aortic stenosis who underwent surgical aortic valve replacement (SAVR) is unknown.All patients with aortic stenosis who underwent isolated first time SAVR in Sweden from 2006 to 2017 and survived six months after discharge were included. Individual patient data from four mandatory nationwide registries were merged. Cox proportional hazards models, with time-updated data on medication status and adjusted for age, sex, comorbidities, type of prosthesis, and year of surgery, were used to investigate associations between dispensed statins, RAS inhibitors, and β-blockers, and all-cause mortality. In total, 9553 patients were included, and median follow-up time was 4.9 years (range 0-11); 1738 patients (18.2%) died during follow-up. Statins were dispensed to 49.1% and 49.0% of the patients within six months of discharge from hospital and after ten years, respectively. Corresponding figures were 51.4% and 53.9% for RAS inhibitors, and 79.3% and 60.7% for β-blockers. Ongoing treatment was associated with lower mortality risk for statins [adjusted hazard ratio (aHR) 0.67 (95% confidence interval 0.60-0.74), p < 0.001] and RAS inhibitors [aHR 0.84 (0.76-0.93), p < 0.001] but not for β-blockers [aHR 1.17 (1.05-1.30), p = 0.004]. The associations were robust in subgroups based on age, sex, and comorbidities (p for interactions > 0.05).The results of this large population-based real-world study support the use of statins and RAS inhibitors for patients who underwent SAVR due to aortic stenosis.

- Introduction First-trimester pregnancy risk evaluation facilitates individualised antenatal care, as well as application of preventive strategies for pre-eclampsia or birth of a small for gestational age infant. A range of early intervention strategies in pregnancies identified as high risk at the end of the first trimester has been shown to decrease the risk of preterm pre-eclampsia (<37 gestational weeks). The aim of this project is to create the Improving Maternal Pregnancy And Child ouTcomes (IMPACT) database; a nationwide database with individual patient data, including predictors recorded at the end of the first trimester and later pregnancy outcomes, to identify women at high risk of pre-eclampsia. A second aim is to link the IMPACT database to a biobank with first-trimester blood samples. Methods and analysis This is a Swedish prospective multicentre cohort study. Women are included between the 11th and 14th weeks of pregnancy. At inclusion, pre-identified predictors are retrieved by interviews and medical examinations. Blood samples are collected and stored in a biobank. Additional predictors and pregnancy outcomes are retrieved from the Swedish Pregnancy Register. Inclusion in the study began in November 2018 with a targeted sample size of 45 000 pregnancies by end of 2021. Creation of a new risk prediction model will then be developed, validated and implemented. The database and biobank will enable future research on prediction of various pregnancy-related complications. Ethics and dissemination Confidentiality aspects such as data encryption and storage comply with the General Data Protection Regulation and with ethical committee requirements. This study has been granted national ethical approval by the Swedish Ethical Review Authority (Uppsala 2018-231) and national biobank approval at Uppsala Biobank (18237 2 2018 231). Results from the current as well as future studies using information from the IMPACT database will be published in peer-reviewed journals.
