    Abstract (CIT): Wednesday Afternoon Lecture Series The Human Functional Genomics Project (HFGP) is a large-scale project that aims to identify the consequences that genetic variation in human DNA and the complex colonization with microbial communities (microbiome) have on the physiological processes in the human body, with a special focus on the immune system in health and human diseases. HFGP includes different deeply phenotyped cohorts with multi-omics information such as transcriptional profiling, gut microbiota composition and extensive immune phenotyping. For her lecture, Dr. Wijmenga will describe the potential of studying variation in the general population and the opportunities for translational research. She will also show how to make use of the LifeLines-deep cohort to establish what constitutes a "normal" gut microbiome and to show how microbiota composition correlates with a range of factors including diet, use of medication, and genetic factors. Her laboratory uses the 500 functional genomics (500FG) cohort to further characterize the interaction between the genetic background of the host, the gut microbiome composition, and the immune response against important human pathogens. The information from both LifeLines-deep and 500FG is subsequently used to identify genes that underlie the genetic susceptibility to systemic candida infections.

    Abstract The past decade has seen enormous success of wide-scale genetic studies in identifying genetic variants that modify individuals' predisposition to common diseases. However, the interpretation and functional understanding of these variants lag far behind. In this Perspective, we discuss opportunities for using large-scale cohort studies to investigate the downstream molecular effects of SNPs at different 'omics' data levels. We point to the pivotal role of population cohorts in establishing causality and advancing drug discovery. In particular, we focus on the breadth-versus-depth concepts of population studies, on data harmonization, and on the challenges, ethical aspects and future perspectives of cohort studies.

    Abstract Autoimmune diseases such as rheumatoid arthritis and coeliac disease are typical examples of complex genetic diseases caused by a combination of genetic and non-genetic risk factors. Insight into the genetic risk factors (single nucleotide polymorphisms (SNPs)) has increased since genome-wide association studies (GWAS) became possible in 2007 and, for individual diseases, SNPs can now explain some 15-50% of genetic risk. GWAS have also shown that some 50% of the genetic risk factors for individual autoimmune diseases overlap between different diseases. Thus, shared risk factors may converge to pathways that, when perturbed by genetic variation, predispose to autoimmunity in general. This raises the question of what determines disease specificity, and suggests that identical risk factors may have different effects in various autoimmune diseases. Addressing this question requires translation of genetic risk factors to causal genes and then to molecular and cellular pathways. Since >90% of the genetic risk factors are found in the non-coding part of the genome (i.e. outside the exons of protein-coding genes) and can have an impact on gene regulation, there is an urgent need to better understand the non-coding part of the genome. Here, we will outline the methods being used to unravel the gene regulatory networks perturbed in autoimmune diseases and the importance of doing this in the relevant cell types. We will highlight findings in coeliac disease, which manifests in the small intestine, to demonstrate how cell type and disease context can impact on the consequences of genetic risk factors.

    Abstract Conventional model systems cannot fully recapitulate the multifactorial character of complex diseases like celiac disease (CeD), a common chronic intestinal disorder in which many different genetic risk factors interact with environmental factors such as dietary gluten. However, by combining recently developed human induced pluripotent stem cell (hiPSC) technology and organ-on-chip technology, in vitro intestine-on-chip systems can now be developed that integrate the genetic background of complex diseases, the different interacting cell types involved in disease pathology, and the modulating environmental factors such as gluten and the gut microbiome. The hiPSCs that are the basis of these systems can be generated from both diseased and healthy individuals, which means they can be stratified based on their load of genetic risk factors. A CeD-on-chip model system has great potential to improve our understanding of disease etiology and accelerate the development of novel treatments and preventive therapies in CeD and other complex diseases.

    Abstract Coeliac disease is a treatable, gluten-induced disease that often occurs concurrently with other autoimmune diseases. In genetic studies since 2007, a partial genetic overlap between these diseases has been revealed and further insights into the pathophysiology of coeliac disease and autoimmunity have been gained. However, genetic screening is not sensitive and specific enough to accurately predict disease development. The current method to diagnose individuals with coeliac disease is serological testing for the presence of autoantibodies whilst the patient is on a regular, gluten-containing diet, followed by gastroduodenoscopy with duodenal biopsy. Serological test results can also predict the probability of coeliac disease development, even if asymptomatic. In patients with autoimmune diseases known to occur alongside coeliac disease (particularly type 1 diabetes mellitus or thyroid disorders), disease screening-and subsequent treatment if coeliac disease is detected-could have beneficial effects on progression or potential complications of both diseases, owing to the effectiveness of gluten-free dietary interventions in coeliac disease. However, whether diagnosis of coeliac disease and subsequent dietary treatment can prevent autoimmune diseases is debated. In this Review, the genetic and immunological features of coeliac disease, overlap with other autoimmune diseases and implications for current screening strategies will be discussed.

    Abstract In the past few years there has been enormous progress in unraveling the genetic basis of celiac disease (CD). Apart from the well-known association to HLA, there are currently 40 genomic loci associated to CD. Most of these loci show pleiotropic effects across many autoimmune diseases and highlight the importance of a dysregulated immune system in the predisposition to CD. It is still too early, however, to use genetics in clinical practice for predicting individual risk. The major challenge for the future is to translate genetic findings into a better understanding of the underlying disease mechanism and to design new ways to treat CD and prevent its development.

    Abstract Background: There have been safety concerns considering long-term proton pump inhibitor (PPI) use, also during pregnancy.
    Aims: To assess the risk of adverse neonatal outcomes associated with maternal intake of PPIs by means of systematic review and meta-analysis.
    Methods: The systematic search included PubMed, Web of Science, Cochrane Database and Embase (inception until June 2019). All studies reporting ≥1 adverse pregnancy outcome comparing PPI users to non-users. Histamine-2 receptor antagonists (H2RA) were also compared to both non-users and PPI users. Outcomes included congenital malformations, abortion, stillbirth, neonatal death, preterm birth, small for gestational age and low birth weight. Pooled odds ratios (OR) and 95% confidence intervals (CI) were obtained by random-effects modelling. PROSPERO study-protocol: CRD42018103320.
    Results: In total, 26 observational studies (20 cohort, 6 case-control studies) were identified, of which 19 assessed PPIs and 12 H2RA. PPI use was associated with an increased risk of congenital malformations (OR 1.28, 95% CI 1.09-1.52), especially in case-control studies (OR 2.04, 1.46-2.86). No associations were found between H2RA and congenital malformations. No significant associations were found between PPI use and abortions, stillbirth, neonatal death, preterm birth and low-birth weight, although H2RA use may be associated with an increased risk of preterm birth (OR 1.25, 95% CI 1.02-1.56). Although statistical heterogeneity and the risk of bias were overall low, clinical heterogeneity, information and selection bias may be present in the individual studies.
    Conclusions: This meta-analysis suggests an association between maternal PPI use and congenital malformations in humans, yet power was insufficient to assess specific malformations and drugs.

    Abstract Background: . In a biopsy-proven adult celiac disease (CeD) cohort from the Netherlands, male patients were diagnosed with CeD at significantly older ages than female patients.
    Objectives: To identify which factors contribute to diagnosis later in life and whether diagnostic delay influences improvement of symptoms after starting a gluten-free diet (GFD).
    Methods: . We performed a questionnaire study in 211 CeD patients (67:144, male:female) with median age at diagnosis of 41.8 years (interquartile range: 25-58) and at least Marsh 2 histology.
    Results: . Classical symptoms (diarrhea, fatigue, abdominal pain and/or weight loss) were more frequent in women than men, but sex was not significantly associated with age at diagnosis. In a multivariate analysis, a non-classical presentation (without any classical symptoms) and a negative family history of CeD were significant predictors of older age at diagnosis (coefficients of 8 and 12 years, respectively). A delay of >3 years between first symptom and diagnosis was associated with slower improvement of symptoms after start of GFD, but not with sex, presentation of classical symptoms or age at diagnosis.
    Conclusion: . Non-classical CeD presentation is more prevalent in men and is associated with a diagnosis of CeD later in life. Recognizing CeD sooner after onset of symptoms is important because a long diagnostic delay is associated with a slower improvement of symptoms after starting a GFD.

    Abstract The mammalian gut is colonized by trillions of microorganisms collectively called the microbiome. It is increasingly clear that this microbiome has a critical role of in many aspects of health including metabolism and immunity. While environmental factors such as diet and medications have been shown to influence the microbiome composition, the role of host genetics has only recently emerged in human studies and animal models. In this review, we summarize the current state of microbiome research with an emphasis on the effect of host genetics on the gut microbiome composition. We focus particularly on genetic determinants of the host immune system that help shape the gut microbiome and discuss avenues for future research.
