EPS4.01 Using a modified glucose challenge test (GCT) as a screening tool for cystic fibrosis diabetes

چکیده
Background: Annual screening for CF-related diabetes (CFRD) is recommended from age 10 in the UK. Regular oral glucose tolerance test (OGTT) or Continuous monitoring (CGM) difficult to achieve (35% of patients ≥10 yr had CFRD 2021, UK CF Registry Data). We currently use CGM at and 14 children with clinical concerns. Objective: To evaluate modified control (GCT) children. Methods: GCT was introduced as part Review (AR). Inclusion criteria: Children ≥ 4 pancreatic insufficiency undergoing blood tests AR. Exclusion Pancreatic sufficient those established CFRD. Sampling: Pre-test fasting not required. 50 g load (as 200 ml Rapilose) given solution be drunk within 5 mins. Patients bloods taken 1 hour later lab HbA1c (in addition other AR bloods).

Serum pancreatic lipase as a screening test for cystic fibrosis.
Pancreatic lipase catalyses the hydrolysis of emulsified triglycerides to form a transparent solution of monoglycerides and fatty acids. Levels of serum pancreatic lipase were measured in neonates known to have cystic fibrosis and compared with levels in control infants. During the first weeks of life infants with cystic fibrosis had raised serum pancreatic lipase values in parallel with raised...

BACKGROUND The frequency of gestational diabetes mellitus (GDM) is 0.6% -15% of pregnant woman. The modern trend towards the delay starting family is the main factor responsible for increase prevalence of GDM. This condition is associated with the adverse effect on mother and fetus, so it is important to find out the GDM by screening of all the pregnant women. OBJECTIVE To observe the feasibi...

Background: The Centers for Disease Control and Prevention estimates that 30 million Americans are living with diabetes and by 2050, 1 out of 3 U.S. adults could develop diabetes. Current screening and diagnostic methods for diabetes mellitus include the oral glucose tolerance test (OGTT), hemoglobin A1c (HbA1c), and fasting plasma glucose (FPG) levels, but each test when used alone will miss a...
