まとめ
自動インスリン投与 (AID) システムは,妊娠中の1型糖尿病患者の血糖コントロールを改善し,範囲内の時間を増加させ,範囲の下の時間を減少させた. 妊娠承認されたAIDシステムについてはさらなる研究が必要である.
科学分野:
- 内分泌学
- 代謝障害
- 糖尿病 管理
背景:
- 自動インスリン投与 (AID) システムは1型糖尿病の主要な治療法ですが,妊娠にはFDAが承認されていません.
- 1型糖尿病の妊婦は,母親と胎児の両方にとって最適な結果を確保するために,注意深い血糖管理を必要とします.
研究 の 目的:
- AIDシステムを使った1型糖尿病の妊婦の血糖コントロールと標準治療を比較する.
- 妊娠中の非処方薬の有効性を評価する.
主な方法:
- 継続的なグルコースモニタリング (CGM) を用いた1型糖尿病の妊婦を含む遡及コホート研究.
- 主要な結果:範囲内の時間 (TIR). 二次的アウトカム:範囲下の時間 (TBR),範囲上の時間,およびグルコース標準偏差.
- AID使用者と標準治療 (複数回毎日の注射とセンサ強化ポンプ療法) の結果の比較
主要な成果:
- AID群 (n=21) は,標準治療群 (n=17) (55. 7% ± 16. 7%) と比較して,有意に高い出産前平均TIRを示した.
- AIDグループは,より低い範囲下での時間 (1. 7% ± 1. 3% vs 3. 0% ± 2. 8%) と,より低いグルコース標準偏差 (37. 2 ± 8. 0 vs 45. 5 ± 8. 9) を達成しました.
- TIRの調整された平均差は7. 9% (95%CI: 0. 8から15. 0; p=0. 03) であった.
結論:
- 妊娠中のAIDシステムの使用は,タイプ1糖尿病患者の範囲内の時間を改善し,範囲下の時間を減少させた.
- 妊娠アルゴリズムでFDAが承認したシステムを待つ間,現在のAIDシステムを最適化するための標準化されたアプローチが必要である.
- 妊娠中の血糖値制御のためのAIDシステムの潜在的な利点を示唆しています.

Diabetes Mellitus: Type 2 and Gestational
2.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Insulin: Dosing Regimen and Adverse Effects
253
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes Mellitus: Overview and Type I Subtype
3.2K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Insulin Formulations: Types and Delivery
269
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into...

Pathophysiology of Diabetes
1.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes: Management and Pharmacotherapy
354
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
