Insights

一种新的测量介质素-2 (IL-2) 释放的全血测定方法可以准确地检测无质饮食患者的乳病 (CeD). 这种简单的测试有助于通过识别质特异性T细胞来诊断CeD.

科学领域:

  • 免疫学 免疫学 免疫学
  • 胃肠病学 胃肠病学
  • 诊断医学 诊断医学 诊断医学

背景情况:

  • 目前的乳病 (CeD) 诊断对于不含谷蛋白饮食 (GFD) 的患者来说具有挑战性.
  • 目前针对质特异性T细胞的血液检测具有敏感性和特异性,但在临床上并不实用.
  • 建议用于CeD诊断使用简单的全血测定测量互白素-2 (IL-2) 释放.

研究的目的:

  • 为了评估测量IL-2释放 (WBAIL-2) 的全血测定,以检测CeD诊断中的质特异性T细胞.
  • 评估WBAIL-2在患有和没有CeD的患者的诊断性能,包括那些使用GFD的患者.
  • 为了比较WBAIL-2与已建立的基于四聚体的方法,并监测谷蛋白挑战后的IL-2水平.

主要方法:

  • 在181名成年人身上进行了WBAIL-2 (88名CeD,93名对照).
  • 在体外质刺激后测量IL-2释放.
  • 测试性能与四聚胺方法进行了比较;血清IL-2和症状在质挑战后进行了监测.

主要成果:

  • 在CeD诊断方面,WBAIL-2的准确性很高,包括在GFD患者中 (90%的灵敏度,HLA-DQ2.5+的95%的特异性).
  • 该测定与质特异性CD4+T细胞频率和血清IL-2水平有很强的相关性.
  • 升高的WBAIL-2预测了质诱导的症状严重程度,并且需要最小的血液体积.

结论:

  • 质刺激的IL-2分泌表明有致病性质特异性CD4+T细胞,这对于诊断CeD很有用.
  • 在WBAIL-2和血清IL-2后的谷蛋白挑战可能使得没有活检的CeD诊断成为可能.
  • WBAIL-2具有诊断和监测其他CD4+T细胞驱动疾病的潜力.

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
