まとめ
免疫チェックポイント阻害剤 (ICI) 誘発型糖尿病 (T1D) は,特に高齢の患者において,急速な発症と進行を呈する. すべての患者は,この状態のためにインスリン治療を必要とします.
科学分野:
- 内分泌学
- 腫瘍学
- 免疫学
背景:
- 免疫チェックポイント阻害剤 (ICI) は 癌治療に革命を起こしています
- しかし,ICIは内分泌病を含む免疫関連の有害事象を引き起こす可能性があります.
- 1型糖尿病 (T1D) は,ICI治療の合併症として認められているが,まれである.
研究 の 目的:
- 免疫チェックポイント阻害剤誘発型糖尿病 (ICI-T1D) の臨床的特徴を解明する.
- ICI-T1Dにおける疾患の重症度に関連する要因を特定する.
- この新たな合併症に対する臨床的管理戦略を策定する.
主な方法:
- ICI- T1Dの24人の患者の遡及症例シリーズ.
- データ収集には,人口統計,ICIの詳細,臨床表現,検査結果が含まれていた.
- マン・ウィトニーUテストを用いた軽度対重度の疾患群の比較
主要な成果:
- ICI- T1Dは主に男性 (87. 5%) で,平均年齢は62. 0歳でした.
- 重篤な症例は高齢化,意識障害,ICI治療期間短縮,疾患進行の加速と関連していた.
- 重度のICI- T1Dでは血糖値が高く,HbA1cが低く, fulminant T1Dの発生率が高く,すべての患者でインスリン治療が必要となった.
結論:
- ICI- T1Dは急性発症と急速な進行が特徴です.
- 高齢は重度のICI-T1Dの危険因子です.
- インスリン治療は,ICI- T1Dと診断されたすべての患者にとって不可欠です.

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...

Pathophysiology of Diabetes

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: Symptoms, Diagnosis, and Complications

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...

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...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Carbohydrate Metabolism

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...
