维持性血液透析患者甲状旁腺体积增大的相关性研究

目的探讨维持性血液透析患者甲状旁腺体积增大的发生率及其相关因素。方法176例维持性血液透析患者,用彩色多普勒测量其甲状旁腺体积,并同时检测患者血清全段甲状旁腺激素(intact parathyroid hormone,iPTH)、血钙、血磷、血清碱性磷酸酶(alkaline phosphatase,AKP)等骨代谢指标。结果1)根据血清iPTH结果176例维持性血液透析患者分为高iPTH组(血清iPTH>300ng/L)84例(47.7%),正常iPTH组(血清iPTH150～300ng/L)32例(18.2%),低iPTH组(血清iPTH<150ng/L)60例(34.1%)。2)176例维持性血液透析患者中有60例伴有甲状旁腺体积增大(34.1%),其中高iPTH组有48例(57.1%)、正常iPTH组4例(12.5%)、低iPTH组8例(13.3%)。高iPTH组患者甲状旁腺体积增大的发生率明显高于正常iPTH组和低iPTH组(P<0.05)。高PTH组甲状旁腺体积增大的程度亦明显高于正常PTH组和低PTH组(P<0.05)。3)甲状旁腺体积增大与透析龄≥5年、不规律服用活性维生素D3制剂的比例、血磷和血碱性磷酸酶水平呈正相关,与血液滤过次数<2次/月和血钙水平呈负相关。结论维持性血液透析患者甲状旁腺体积增大的发生率较高,多发生于甲状旁腺激素高分泌组。透析龄、不规律服用活性维生素D3制剂、血iPTH是甲状旁腺体积增大的独立危险因素。

The Association of Parathyroid Gland Enlargement and Risk Factors in Patients with Maintenance Hemodialysis

Objective To investigate the incidence and risk factors of parathyroid gland enlargement in patients on maintenance hemodialysis.Methods A total of one hundred and seventy-six cases with uremia on maintenance hemodialysis were studied in terms of parathyroid gland size and bone metabolism index,such as serum intact parathyroid hormone(iPTH),calcium,phosphorus and alkaline phosphatase(ALP) etc.Results 1) According to the result of serum iPTH,176 patients with uremia on maintenance hemodialysis were divided i...
