Brief Summary:
Glucose fluctuations present not only in patients with diabetes mellitus but also in subjects with normal glucose tolerance or impaired glucose regulation. People with Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome are at risk of impaired glucose metabolism. Glycemic variability is poorly studied in the nondiabetic individuals. The aim of the study is to investigate the characteristics of glucose fluctuations in the newly diagnosed Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome individuals.

Condition or disease Intervention/treatment
Pituitary Adenoma Device: continuous glucose monitoring

Detailed Description:

Glucose fluctuations present not only in patients with diabetes mellitus but also in subjects with normal glucose tolerance or impaired glucose regulation. Compared with traditional monitoring methods, continuous glucose monitoring system(CGMS) techniques provides a much more detailed understanding of shifting blood glucose levels throughout the day.It is considered reliable to evaluate glucose variability not only in patients with diabetes but also in nondiabetic individuals.

People with Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome are at risk of impaired glucose metabolism and developing diabetes mellitus.Some researchers have shown that 15-30% Growth Hormone-Secreting Pituitary Adenoma are suffering from diabetes, 15-36% impaired glucose regulation. The rate of Cushing Syndrome individuals is 10-30% and 40-45% separately.

Glycemic variability is poorly studied in the nondiabetic individuals and has not been studied in the newly diagnosed Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome individuals. In this study CGM was used to dynamically monitor patients being newly diagnosed with Growth Hormone-Secreting Pituitary Adenoma and Cushing Syndrome.

Intervention Details:
  • Device: continuous glucose monitoring
    Patients newly diagnosed GH-releasing pituitary adenoma or Cushing Syndrome in our department will be monitored blood glucose by CGMS Gold.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Continuous glucose profiles of mean data of 24-hour continuous glucose monitoring by the CGMS Gold [ Time Frame: 3 days ]
    The monitoring results consisted of one curve and 5 parameters


Secondary Outcome Measures :
  1. The mean amplitude of glycemic excursion of newly diagnosed GH adenoma patients [ Time Frame: 3 days ]
    The mean amplitude of glycemic excursion of newly diagnosed GH adenoma patients during the 3 days monitored by CGMS Gold

  2. The mean amplitude of glycemic excursion of newly diagnosed Cushing Syndrome patients during the 3 days monitored by CGMS Gold [ Time Frame: 3 days ]
    The mean amplitude of glycemic excursion of newly diagnosed Cushing Syndrome patients during the 3 days monitored by CGMS Gold

  3. The correlation of MAGE and IGF-1 in newly diagnosed GH adenoma patients [ Time Frame: 6 months ]
    By compared with the outcomes after treated by SSAs or surgery we want to get weather there is a correlation between MAGE and IGF-1 in GH adenoma patients

  4. The correlation of MAGE and cortison in newly diagnosed Cushing Syndrome patients [ Time Frame: 6 months ]
    By compared with the outcomes after treated by surgery we want to get weather there is a correlation between MAGE and cortison in Cushing Syndrome patients
