The current paradigm in pediatric dentistry is that children and adolescents with CF are at low risk for dental caries. The antibiotics used chronically as part of CF treatment are thought to protect against caries. However, a recent systematic review authored by the PI suggests loss of protection against caries as children with CF enter adolescence. A potential explanation is that the life-protecting antibiotic regimens used to treat CF change as children with CF get older. Most children with CF use penicillins, which kill Gram-positive oral bacteria that cause caries (S. mutans). Adolescents with CF also use inhaled tobramycin, which does not kill Gram-positive oral bacteria. In addition, tobramycin may create selective ecologic pressure in favor of caries-causing bacteria because it kills Gram-negative oral bacteria. In addition, permanent tooth decay rates for patients with CF are greater than the U.S. mean caries rate, which suggests that caries in adolescents with CF is an important but overlooked issue. These observations warrant a critical reevaluation of a potentially flawed paradigm. We will collect primary clinical and survey data to achieve the following Specific Aim:<\/p>\n<p>To investigate the medical, biological\/intraoral, and behavioral risk factors associated with caries for 35 children (ages 6 to 11 years), 35 adolescents (ages 12 to 17 years), and 30 young adults (ages 18 to 25 years) with CF.<\/p>\n<p>We will recruit and enroll 100 children, adolescents, and young adults with CF from Seattle Children\u2019s Hospital. From these participants, we will collect survey data (from parents), saliva samples, and oral health data. The data generated from this pilot study will help refine the model of risk factors for dental caries and form the basis for a R01 grant application that proposes a longitudinal study of caries risk factors in children, adolescents, and young adults with CF. The long-term goal is to develop a multilevel clinical intervention to prevent caries in CF patients.<\/p>\n<p>Our main study hypothesis is that adolescents with cystic fibrosis (CF) are at increased risk for dental caries compared to children with CF. We will test our hypothesis through the following Specific Aim:<\/p>\n<p>To investigate the medical, biological\/intraoral, and behavioral risk factors associated with caries for 100 individuals with CF.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pilot 12: Identification of Biomarkers for Cystic Fibrosis Associated Nephrotoxicity<\/p>\n<p>P.I.:  \tNeal Paragas, PhD<br \/>\n\tResearch Assistant Professor,<br \/>\n\tMedicine (Nephrology)<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"<p>P.I.: <a href=\"http:\/\/depts.washington.edu\/metab\/directory\/faculty\/steven-e-kahn-m-b-ch-b\/\" target=\"_blank\">Steven Kahn, MB, ChB<\/a><br \/> Professor of Medicine<br \/> Metabolism, Endocrinology and Nutrition<\/p><p><a href=\"http:\/\/depts.washington.edu\/metab\/directory\/faculty\/kristina-utzschneider-m-d\/\" target=\"_blank\">Kristina Utzschneider, MD<\/a><br \/> Associate Professor of Medicine<br \/> Metabolism, Endocrinology and Nutrition<\/p><p>With the increased life expectancy of patients with cystic fibrosis (CF), other co-morbidities have become apparent in these patients. One of these is abnormal glucose metabolism, where CF-related diabetes (CFRD) is common. More recently, another abnormality of glucose metabolism has been recognized; namely late hypoglycemia following oral glucose loading. In this study, we propose to test the hypothesis that the post-glucose load hypoglycemia observed in patients with CF results from a deficient counterregulatory hormone response and\/or an insulin response that is exaggerated and delayed. This increased insulin response could be the result of an exaggerated incretin hormone response or altered gastric emptying. To address this hypothesis, we will perform a 3-hour oral glucose tolerance test during which we will measure counterregulatory, islet and incretin hormone responses and determine the rate of gastric emptying using acetaminophen. To determine whether patients with CF and late hypoglycemia also have episodes of hypoglycemia during daily living that includes mixed meals, we will use a continuous glucose monitoring system (CGMS) to examine 24-hour glucose profiles for 3 days. All these measures will be compared between patients with CF who develop late hypoglycemia, CF patients who do not develop hypoglycemia, and age and body mass index-matched healthy controls. The findings from this study will provide important new information regarding the mechanism(s) responsible for the late hypoglycemia observed in patients with CF and the data could be used as the basis for future grant applications. The ultimate goal is to gain insight into the condition of late hypoglycemia in order to better manage patients with CF.<\/p>","_et_gb_content_width":"","_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[12],"tags":[],"_links":{"self":[{"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/posts\/1251"}],"collection":[{"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/comments?post=1251"}],"version-history":[{"count":3,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/posts\/1251\/revisions"}],"predecessor-version":[{"id":1255,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/posts\/1251\/revisions\/1255"}],"wp:attachment":[{"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/media?parent=1251"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/categories?post=1251"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/depts.washington.edu\/cfrtc\/wp-json\/wp\/v2\/tags?post=1251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
