What is IMMUNE TOLERANCE? What does IMMUNE TOLERANCE mean? IMMUNE TOLERANCE meaning - IMMUNE TOLERANCE definition - IMMUNE TOLERANCE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Immune tolerance or immunological tolerance describes a state of unresponsiveness of the immune system to substances or tissue that have the capacity to elicit an immune response. It contrasts with conventional immune-mediated elimination of foreign antigens (see Immune response). Tolerance is classified into central tolerance or peripheral tolerance depending on where the state is originally inducedin the thymus and bone marrow (central) or in other tissues and lymph nodes (peripheral). The mechanisms by which these forms of tolerance are established are distinct, but the resulting effect is similar. Immune tolerance is important for normal physiology. Central tolerance is the main way the immune system learns to discriminate self from non-self. Peripheral tolerance is key to preventing over-reactivity of the immune system to various environmental entities (allergens, gut microbes, etc.). Deficits in central or peripheral tolerance also cause autoimmune disease, resulting in syndromes such as systemic lupus erythematosus, rheumatoid arthritis, type 1 diabetes, autoimmune polyendocrine syndrome type 1 (APS-1), and immunodysregulation polyendocrinopathy enteropathy X-linked syndrome (IPEX), and potentially contribute to asthma, allergy, and inflammatory bowel disease. Tolerance, however, also has its negative tradeoffs. It allows for some pathogenic microbes to successfully infect a host and avoid elimination. In addition, inducing peripheral tolerance in the local microenvironment is a common survival strategy for a number of tumors that prevents their elimination by the host immune system.

Glucose Tolerance: Gestational Diabetes Mellitus

American Diabetes Association (ADA) Recommendations Note: The American College of Obstetricians and Gynecologists maintains a different set of recommendations for the screen and diagnosis of gestational diabetes mellitus. The ACOG recommendations follow below. Rationale: The American Diabetes Association (ADA) 2015 Standards of Medical Care provide the following recommendations regarding the diagnosis of gestational diabetes mellitus.1,2 Screen for undiagnosed type 2 diabetes at the first prenatal visit in those with risk factors, using criteria described for diabetes mellitus. In pregnant women not known to have diabetes, screen for gestational diabetes mellitus (GDM) at 24 to 28 weeks of gestation, using the Gestational Glucose Tolerance Screening and Diagnostics Test (Two-hour, ADA Recommendations) (101000). The diagnosis is made when any of the following plasma glucose values are exceeded: Fasting glucose ≥92 mg/dL One-hour glucose ≥180 mg/dL Two-hour glucose ≥153 mg/dL Screen women with GDM for persistent diabetes 6 to 12 weeks postpartum using the criteria described under nongestational diabetes mellitus. Women with a history of GDM should have lifelong screening for th Continue reading >>

    I love technology. But in this moment it's driving me insane because I'm impatient and worried. I had to take the 1-hour glucose test early because of my bmi. The test results were posted on my online chart. My glucose level was 126 mg/dL, and my doctor flagged the test. The normal range listed in the results said 65-99 mg/dL.
    But from everything I read online about the 1 hour glucose test, anything under 140 mg/dL is fine, and under 130 is even better. I read that a fasting glucose level higher than 99 is worrisome; but I wasn't fasting obviously because I drank the sugar drink and had lunch 2 hours prior. I'm so confused. Ill certainly be calling my doctor tomorrow. But before I stay up all night worrying I have diabetes does anyone know anything about this?

    I am guessing they are going to have you repeat the test later in pregnancy like 22-24wks because you are borderline.

    I agree, talk to your doc, but my doctor said anything under 140 on the 1-hour was totally normal since it's not a fasting test. Did your doctor know that you weren't fasting before the one hour (I mean, besides the drink, did they know you had eaten that day)? I'd let them know. It's possible that they are testing you for an underlying blood sugar issue and not for GD.
    The main thing to keep in mind is that the 1-hour is just a screen. It's to pick up anyone who might be having an issue. The 3-hour is diagnostic. So it's totally possible to fail the one hour and still have absolutely no issues.

1 Hour Glucose Test - Normal Range Is What?

1 hour Glucose Test - Normal Range is what? What did your doctor use as the normal range for the result of the glucose test? Mine is using less than 135. My result was 135. When I was pregnant with my son 4 years ago, the normal range was less than 140. Everything I am reading online (from reputable sources, including the U.S. Library of Medicine - updated June 2014 - indicates that the threshold is less than 140. I really do not want to have to take the 3 hour test for this result if it really should be based on a less than 140 result. Any insights? Thanks! Just depends on your physician and the lab they use. Some labs run things differently - therefore results in slightly different levels. Plus it could be if it was the same physician for you they've just made their rules more strict I've had different Dr's with both pregnancies in different offices and both used 140 for me. My cutoff is 134 and my result was 136. I had to do 3-hr test and passed. The ACOG says OBs can use 130 or 140 as the cutoff, or anything in between. My OB used 135 at her previous practice so she "passed" me at 134. But she is considering having me test again due to high AFI and large baby since I was borde Continue reading >>

Relationship Between 1-hour Glucose Challenge Test Results And Perinatal Outcomes

Go to: Abstract To estimate the relationship between 1-hour 50 gm glucose challenge test (GCT) values and perinatal outcomes. Methods This was a secondary analysis of data from a multicenter treatment trial of mild gestational diabetes mellitus (GDM). Women with GCT 135199 mg/dL completed a 3-hour oral glucose tolerance test (OGTT). Mild GDM was defined as fasting glucose less than 95 mg/dL and two or more abnormal OGTT values: 1-hour 180 mg/dL or more; 2-hour 155 mg/dL or more; 3-hour 140 mg/dL or more. Our study included untreated women with GCT 135–139 mg/dL, GCT 140–199 mg/dL, and a comparison group with GCT less than 120 mg/dL. Primary outcomes included a perinatal composite (stillbirth, neonatal death, hypoglycemia, hyperbilirubinemia, neonatal hyperinsulinemia, and birth trauma), large for gestational age (LGA, birth weight above the 90th percentile based on gender and race specific norms) and macrosomia (greater than 4,000gm). There were 436 women with GCT less than120 mg/dL and 1,403 with GCT 135 mg/dL or more (GCT 135–139, n=135; 140–199, n=1,268). The composite perinatal outcome occurred in 25.6% of those with GCT less than 120 mg/dL compared with 21.1% for GCT 1 Continue reading >>
