概括
患有自身免疫性甲状腺炎 (AT) 的孕妇服用勒沃西 (L-T4) 益处于含有的补充剂 (ICS). 使用ICS显著改善状态,但应根据L-T4剂量调整补充剂量以优化结果.
科学领域:
- 内分泌学 在内分泌学.
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 营养科学 营养科学
背景情况:
- 对于甲状腺激素的合成至关重要,对于胎儿的神经发育至关重要.
- 对于接受Levothyroxine (L-T4) 治疗的孕妇,含补充剂 (ICS) 的必要性仍在争论中.
- 自身免疫性甲状腺炎 (AT) 在怀孕期间影响甲状腺功能和需求.
研究的目的:
- 评估怀孕妇女与AT的状态,比较那些在L-T4治疗与那些没有接受它.
- 评估含补充剂 (ICS) 对该人群中水平的影响.
- 调查ICS使用,L-T4剂量和新生儿甲状腺刺激激素 (TSH) 水平之间的关系.
主要方法:
- 对被诊断患有AT的孕妇进行横截面观察性研究.
- 采集尿样以测量尿液中度 (UIC) 的正常化到肌素 (UI/Creat).
- 评估甲状腺功能 (TSH,FT4) 和新生儿TSH水平;通过问卷和医疗记录收集的数据.
主要成果:
- 使用ICS的女性表现出明显更高的UI/Creat水平 (74.1%),而非使用者 (46.2%).
- ICS使用是充足状态的唯一独立预测因素 (UI/Creat ≥150μg/g).
- 使用ICS的母亲出生的婴儿显示新生儿TSH水平升高,TSH>5mIU/L的所有病例都发生在这个群体中.
结论:
- 接受L-T4治疗的孕妇需要补充.
- 补充剂的量应仔细管理,并根据个人L-T4剂量进行潜在调整.
- 虽然ICS可以改善母亲的状况,但对新生儿TSH的潜在影响需要进一步调查和仔细监测.

Synthesis and Regulation of Thyroid Hormones
4.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
2.5K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
304
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Autoimmune Disorders
379
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Radiological Investigation I: X-ray and CT
203
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
141
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
