Diagnosis and Glycemic Control of Type 1 Diabetes / 임상당뇨병

Type 1 diabetes mellitus (T1DM) is characterized by an immune-mediated beta-cell destruction that causes lifelong insulin dependency. Diagnosis of diabetes is based on fasting glucose, 2-h plasma glucose value after a 75-g oral glucose tolerance test, or hemoglobin A1c (HbA1c) levels. Differentiation between type 1 and 2 diabetes is important for both education and treatment. Diabetes-associated autoantibodies, c-peptide and clinical characteristics should be considered to confirm the diagnosis of T1DM. A single HbA1c target of < 7.5% across all pediatric age groups is recommended. In nonpregnant adults, a reasonable HbA1c goal is < 7.0% to reduce the incidence of microvascular complications of T1DM. Glycemic targets should be individualized according to lifestyle, psychosocial and medical circumstances.

A survey on the current status of type 2 diabetic patients who failed to achieve the glycemic control target / 中华内分泌代谢杂志

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged ＞ 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P＜0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged ＞60 years (58.7%;Compared with the other age-groups, all P＜0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.
