まとめ
血漿上皮成長因子(EGF)濃度の低下は、2型糖尿病(T2D)および血糖コントロール不良と関連している。これは、EGFが糖尿病の調節異常のバイオマーカーとなる可能性を示唆している。
科学分野:
- 内分泌学
- 代謝性疾患
- 生化学
背景:
- 上皮成長因子(EGF)は、膵臓β細胞機能およびグルコース恒常性にとって不可欠である。
- EGF欠乏は糖尿病動物モデルで認められているが、ヒトの2型糖尿病(T2D)、特に肥満との関連におけるその役割は不明である。
研究 の 目的:
- T2Dのある患者とない患者における血漿EGF濃度を調査すること。
- EGFと血糖コントロールおよび臨床パラメータとの関連を評価すること。
- これらの関連における肥満の影響を決定すること。
主な方法:
- 214人のT2D患者と214人の非糖尿病患者を含む428人の参加者(クウェート糖尿病疫学プログラムから)を対象とした症例対照研究。
- ELISAを用いて血漿EGF濃度を定量化した。
- 統計解析には、ピアソン相関、重回帰分析、ロジスティック回帰分析が含まれた。
主要な成果:
- T2D患者では、非糖尿病患者と比較して血漿EGF濃度が有意に低かった(p<0.001)。
- 非糖尿病患者では、肥満はEGF濃度の低下と関連していた(p=0.03)が、T2D患者では関連は認められなかった。
- EGF濃度の低下は、T2D(OR=0.996、p=0.001)およびT2D患者における空腹時血糖、HbA1C、トリグリセリド、および腹囲/臀囲比との負の相関と独立して関連していた。
結論:
- EGF濃度の低下は、T2Dおよび血糖コントロール不良と強く関連している。
- EGFは、T2Dにおける血糖調節異常のバイオマーカーとしての可能性を示す。
- T2Dの病態生理および合併症におけるEGFの役割をさらに調査する必要がある。

Diabetes Mellitus: Type 2 and Gestational
4.3K
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...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Hypoglycemia and Glucagon
838
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
