• Genomic Predictors of Combat Stress Vulnerability and Resilience

  The Genomic Predictors of Combat Stress Vulnerability and Resilience Study was designed to probe the likely hereditary basis for risk or resilience to develop PTSD and other trauma spectrum disorders. The overall guiding hypothesis was that genomic variation gives rise to risk/susceptibility traits that, when actuated by traumatic environmental stimuli, such as combat, give rise to PTSD and other stress-related phenotypes. Two studies designed to identify risk and resilience factors for combat-induced, stress-related symptoms are being conducted by our group: The Marine Resiliency Study (MRS) is a prospective PTSD study with longitudinal follow-up (pre- and post-exposure to combat stress) of US Marines bound for deployment to Iraq or Afghanistan. Extensive phenotyping includes 3 domains: Psychosocial, Psychophysiologic, and Biophysiologic. The biological and physiological measures collected were chosen in part due to their potential to serve as intermediate phenotypes for stress-related disorders. A second, cross-sectional study involves a cohort of combat-exposed active duty or previously deployed service members (CAVC), including PTSD cases and controls with comparable psychosocial and clinical phenotypes. Little information is available about the factors that explain why some trauma survivors develop stress disorders and some do not. It is hoped that the insights gained from this approach will improve understanding of the genetic contributors to PTSD, and potentially provide novel diagnostic tests and therapeutic approaches to this currently enigmatic and difficult-to-manage condition.

• Genetics of 24 hour urine composition

  Genetic and environmental factors play an important role in the etiology of nephrolithiasis. This project will build on and extend our previous efforts (examining environmental risk factors for stone formation) by allowing us to study the risk of stone formation associated with specific genes and gene-environment interactions. We will take advantage of previously collected data in three large cohort studies: Nurses' Health Study I (n=121,000 women), Nurses' Health Study II (n=116,000 women), and Health Professionals Follow-up Study (n=51,000 men). Over a period of 17 to 26 years, information has been collected prospectively on important exposures including diet, family history, body size measures, past medical history, and medications. We have confirmed over 2000 incident cases of kidney stones in each cohort (DK59583, PI Curhan). Further, we have collected 24-hour urine samples from over 4100 stone formers and non-stone formers; the majority of participants have performed two collections. The primary objective of this project is to examine the association between single nucleotide polymorphisms and the 24-hour urinary excretion of stone promoters (calcium and oxalate) and a stone inhibitor (citrate). The secondary objective is to explore the impact of interactions between the genetic factors and dietary factors on 24-hour urinary excretion of relevant lithogenic factors. These findings should provide new insight into regulation of these important factors and also into novel approaches for prevention of stone formation.

• Risk Factors for Asymptomatic Diverticulosis

  Data for this analysis came from a prospective study of colonic diverticulosis at the University of North Carolina Hospital in Chapel Hill, North Carolina (NIH R01DK094738). This is a case-control genetic and transcriptomic study to identify the genetic and cellular determinants underlying colonic diverticulosis and the relationship with other gastrointestinal disorders. The study inclusion and exclusion are described below. DNA and RNA sequencing were performed on colonic tissue from 404 patients with (N=172) and without (N=232) diverticulosis. We assessed variation in the transcriptome associated with diverticulosis and integrated this variation with human intestine single-cell RNA-seq data. We integrated our expression quantitative trait loci with GWAS using Mendelian Randomization. A polygenic risk score analysis examined associations between severity of diverticulosis and other gastrointestinal disorders. We identified 38 genes with differential expression and 17 genes with varied transcript usage linked to diverticulosis. Our results suggest tissue remodeling as a primary mechanism for diverticula formation. The presence of diverticulosis was linked to stromal and epithelial cells in the colon including endothelial cells, myofibroblasts, fibroblasts, goblet, tuft, enterocytes, neurons, and glia. MR highlighted five genes including CCN3, CRISPLD2, ENTPD7, PHGR1, and TNFSF13. In diverticulosis cases, ENTPD7 upregulation was confirmed. A greater burden of diverticula was positively correlated with genetic predisposition to diverticulitis. The data related to the study including total RNA-Seq, SNP array and imputed genotypes will be available through dbGaP.

• Field studies of Cryptosporidiosis and Enteropathogens in Bangladesh

  Cryptosporidiosis causes severe diarrhea in infants in the developing world. There is no vaccine to prevent it, and little in the way of treatment. This study on Bangladeshi urban slum children aims to support the design of a vaccine, both by determining how the immune system protects from infection and by identifying the genotypes of the parasite that should be included in a vaccine, as well as aid in development of therapies by identifying human genes that control infection. The primary objective of the study was to determine the incidence and contribution to disease of the different species and genotypes of cryptosporidia. Secondary objectives were designed to determine acquired immune response to cryptosporidiosis and identify human genes that influence susceptibility to cryptosporidiosis. This is an observational study. Children were recruited from Mirpur Dhaka slum (Cohort 1) and rural Mirzapur (Cohort 2) and followed for cryptosporidium infection longitudinally from birth through age 4 years in Cohort 1 and birth through age 2 years in Cohort 2. Biweekly household visits for diarrheal surveillance were made in addition to anthropometric measurements of mother and child, blood samples collected two times each year from the child, a work-up of diarrheal stools and non-diarrheal surveillance stools for cryptosporidium and other enteropathogens, and blood and breast milk samples from the mother. A detailed description of the study design and procedures can be obtained from publication: Kevin L Steiner, et al., 2018, PMID: 29897482.

• Longitudinal Study of Immune Mediated Disorders After Allogenic Hematopoietic Cell Transplantation (HCT)

  Allogeneic hematopoietic cell transplantation (HCT) is the only known curative option for many hematologic disorders. After transplantation, many patients develop immune mediated disorders that may be life-threatening. Post-HCT immune mediated disorders are rare relative to other diseases but the prototype of graft versus host disease (GVHD) develops in 30-70% of patients. The morbidity and mortality associated with these HCT-associated immune mediated disorders are major barriers to successful use of transplantation to cure rare hematologic malignancies such as leukemia, lymphoma, multiple myeloma, myelodysplastic/myeloproliferative syndromes amongst other diseases. The purpose of this study is to characterize and more completely define the onset and course of immune mediated disorders after allogeneic HCT, focusing on participants who develop cutaneous sclerosis, bronchiolitis obliterans syndrome (BOS), late acute graft-vs.-host disease (GVHD), and chronic GVHD. Of the participants undergoing allogeneic hematopoietic cell transplantation (HCT), can we, the researchers better identify who will develop immune-mediated disorders, what types of disorders participants will have, and whether these disorders will be severe or respond to currently available therapies? This is a longitudinal study of 1118 individuals (1081 adults and 100 children). Those participating in this study will be evaluated over a 3 year period at 9 study sites. Participants will be enrolled pre-transplant, or up to day 121 post transplantation. This wide enrollment window will allow sites to use recruitment methods that are most efficient at their institutions. At least 2 years of follow-up will ensure an adequate sample size, and sufficient time for observation of the full spectrum of immune mediated disorders. The data of 1023 individuals have been submitted to dbGaP.
