Item Autoimmune Diseases in Children and Adults With Type 1 Diabetes From the T1D Exchange Clinic Registry(Oxford University Press, 2016-09-27) Hughes, Jing W.; Riddlesworth, Tonya D.; DiMeglio, Linda A.; Miller, Kellee M.; Rickels, Michael R.; McGill, Janet B.; Pediatrics, School of MedicineBackground and Aims: Type 1 diabetes (T1D) is associated with other autoimmune diseases (AIDs), but the prevalence and associated predictive factors for these comorbidities of T1D across all age groups have not been fully characterized. Materials and Methods: Data obtained from 25 759 participants with T1D enrolled in the T1D Exchange Registry were used to analyze the types and frequency of AIDs as well as their relationships to gender, age, and race/ethnicity. Diagnoses of autoimmune diseases, represented as ordinal categories (0, 1, 2, 3, or more AIDs) were obtained from medical records of Exchange Registry participants. Results: Among the 25 759 T1D Exchange participants, 50% were female, 82% non-Hispanic white, mean age was 23.0 ± 16.9 years and mean duration of diabetes was 11 years. Of these participants, 6876 (27%) were diagnosed with at least one AID. Frequency of two or more AIDs increased from 4.3% in participants aged younger than 13 years to 10.4% in those aged 50 years or older. The most common AIDs were thyroid (6097, 24%), gastrointestinal (1530, 6%), and collagen vascular diseases (432, 2%). Addison’s disease was rare (75, 0.3%). The prevalence of one or more AIDs was increased in females and non-Hispanic whites and with older age. Conclusions: In the T1D Exchange Clinic Registry, a diagnosis of one or more AIDs in addition to T1D is common, particularly in women, non-Hispanic whites, and older individuals. Results of this study have implications for both primary care and endocrine practice and will allow clinicians to better anticipate and manage the additional AIDs that develop in patients with T1D.Item Development and Validation of Model Consisting of Comorbidity Burden to Calculate Risk of Death Within 6 months for Patients With Suspected Drug-Induced Liver Injury(Elsevier, 2019-11) Ghabril, Marwan; Gu, Jiezhun; Yoder, Lindsay; Corbito, Laura; Ringel, Amit; Beyer, Christian D.; Vuppalanchi, Raj; Barnhart, Huiman; Hayashi, Paul H.; Chalasani, Naga; Medicine, School of MedicineBackground & Aims: Patients with drug-induced liver injury (DILI) frequently have comorbid conditions, but the effects of non-liver comorbidities on outcome is not well understood. We investigated the association between co-morbidity burden and outcomes of patients with DILI, and developed and validated a model to calculate risk of death within 6 months. Methods: A multiple logistic regression model identified variables independently associated with death within 6 months of presenting with suspected DILI (6-month mortality) for 306 patients enrolled in the DILIN prospective study at Indiana University (discovery cohort). The model was validated using data from 247 patients with suspected DILI enrolled in the same study at the University of North Carolina (validation cohort). Medical comorbidity burden was calculated using the Charlson comorbidity index—patients with scores higher than 2 were considered to have significant comorbidities. Results: Six-month mortality was 8.5% in the discovery cohort and 4.5% in the validation cohort. In the discovery cohort, significant comorbidities (odds ratio [OR], 5.4; 95% CI 2.1 – 13.8), model for end-stage liver disease score (OR, 1.11; 95% CI, 1.04–1.17), and serum level of albumin at presentation (OR, 0.39; 95% CI, 0.2–0.76) were independently associated with 6-month mortality. A model based on these 3 variables identified patients who died within 6 months with c-statistic values of 0.89 (95% CI, 0.86–0.94) in the discovery cohort and 0.91 (95% CI, 0.83–0.99) in the validation cohort. We developed a web-based calculator to determine risk of death within 6 months for patients with suspected DILI for use in the clinic. Conclusions: We developed and validated a model based on comorbidity burden, model for end-stage liver disease score, and serum level of albumin that predicts 6-month mortality in patients with suspected DILI.Item Different rates of cognitive decline in autosomal dominant and late-onset Alzheimer disease(Wiley, 2022-10) Buckles, Virginia D.; Xiong , Chengjie; Bateman, Randall J.; Hassenstab, Jason; Allegri, Ricardo; Berman, Sarah B.; Chhatwal, Jasmeer P.; Danek, Adrian; Fagan, Anne M.; Ghetti, Bernardino; Goate, Alison; Graff-Radford, Neill; Jucker, Mathias; Levin, Johannes; Marcus, Daniel S.; Masters, Colin L.; McCue, Lena; McDade, Eric; Mori, Hiroshi; Moulder, Krista L.; Noble, James M.; Paumier , Katrina; Preische, Oliver; Ringman, John M.; Fox, Nick C.; Salloway, Stephen; Schofield, Peter R.; Martins, Ralph; Vöglein, Jonathan; Morris, John C.; Dominantly Inherited Alzheimer Network; Pathology and Laboratory Medicine, School of MedicineAs prevention trials advance with autosomal dominant Alzheimer disease (ADAD) participants, understanding the similarities and differences between ADAD and “sporadic” late-onset AD (LOAD) is critical to determine generalizability of findings between these cohorts. Cognitive trajectories of ADAD mutation carriers (MCs) and autopsy-confirmed LOAD individuals were compared to address this question. Longitudinal rates of change on cognitive measures were compared in ADAD MCs (n=310) and autopsy-confirmed LOAD participants (n=163) before and after symptom onset (estimated/observed). LOAD participants declined more rapidly in the presymptomatic (preclinical) period and performed more poorly at symptom onset than ADAD participants on a cognitive composite. After symptom onset, however, the younger ADAD MCs declined more rapidly. The similar but not identical cognitive trajectories (declining but at different rates) for ADAD and LOAD suggest common AD pathologies but with some differences.Item Pancreas transplantation would be easy if the recipients were not diabetic: A practical guide to post-operative management of diabetic complications in pancreas transplant recipients(Wiley, 2021-05) Cerise, Adam; Chen, Jeanne M.; Powelson, John A.; Lutz, Andrew J.; Fridell, Jonathan A.; Surgery, School of MedicineDiabetes mellitus remains a major public health problem throughout the United States with over $300 billion spent in total cost of care annually. In addition to being a leading cost of kidney failure, diabetes causes a host of secondary hyperglycemic-related complications including gastroparesis and orthostatic hypotension. While pancreas transplantation has been established as an effective treatment for diabetes, providing long-term normoglycemia in recipients, the secondary complications of diabetes mellitus persist complicating the post-operative course of an otherwise successful pancreas transplantation. This review describes the mechanism and impact of diabetic gastroparesis and orthostatic hypotension in the post-operative course of pancreas transplant patients and analyzes the various treatment modalities, based on current data and extensive experience at our institution, to treat these respective complications. While gastroparesis and orthostatic hypotension remain challenging post-operative conditions, the establishment of institutional protocols and step-up treatment algorithms can help define more effective therapies.Item Prevalence of Medical and Psychiatric Comorbidities Following Traumatic Brain Injury(Wolters Kluwer, 2019-08-01) Hammond, Flora M.; Corrigan, John D.; Ketchum, Jessica M.; Malec, James F.; Dams-O'Connor, Kristen; Hart, Tessa; Novack, Thomas A.; Bogner, Jennifer; Dahdah, Marie N.; Whiteneck, Gale G.; Physical Medicine and Rehabilitation, School of MedicineObjective: To examine the prevalence of selected medical and psychiatric comorbidities that existed prior to, or up to 10 years following, traumatic brain injury (TBI) requiring acute rehabilitation. Design: Retrospective cohort. Setting: Six TBI Model Systems centers. Participants: 404 participants in the TBI Model System National Database who experienced TBI 10 years prior. Interventions: Not applicable. Main Outcome Measure: Self-reported medical and psychiatric comorbidities and the onset time of each endorsed comorbidity. Results: At 10 years post-injury, the most common comorbidities developing post-injury, in order, were: back pain, depression, hypertension, anxiety, fractures, high blood cholesterol, sleep disorders, panic attacks, osteoarthritis, and diabetes. Comparing those 50 years and older to those less than 50 years, diabetes (OR = 3.54; p = 0.0016), high blood cholesterol (OR = 2.04; p = 0.0092), osteoarthritis (OR = 2.02; p = 0.0454), and hypertension (OR = 1.84; p = 0.0175) were significantly more prevalent in the older cohort while panic attacks (OR = 0.33; p = 0.0022) were significantly more prevalent in the younger cohort. No significant differences in prevalence rates between the older and younger cohorts were found for back pain, depression, anxiety, fractures, or sleep disorders. Conclusions: People with moderate-severe TBI experience other medical and mental health comorbidities during the long-term course of recovery and life after injury. The findings can inform further investigation into comorbidities associated with TBI and the role of medical care, surveillance, prevention, lifestyle, and healthy behaviors in potentially modifying their presence and/or prevalence over the life span.
