目的探讨甲状腺功能亢进（简称甲亢）手术后出现骨饥饿综合征的发病机理。方法回顾性分析四川大学华西医院2009年收治的2例甲亢手术后严重低钙患者的临床资料。结果本组2例病例在甲亢手术后均出现了严重低钙血症，1例低镁血症; 2例病例手术前、后骨代谢碱性磷酸酶均有不同程度升高。结论甲亢手术后骨饥饿综合征是多因素造成的临床症状，所以对手术后低钙症状应给予正确分析和判断，并尽可能在问题出现前给予预测和处理。对于甲亢患者和绝经期女性在围手术期给予钙的补充，手术中注意保存甲状旁腺血供是减少骨饥饿综合征的最佳手段，甲亢手术后及时补钙是必要的。
ObjectiveTo summarize the mechanism, risk factors, clinical manifestations, and medical treatment of hungry bone syndrome (HBS) in patients with hyperparathyroidism after parathyroidectomy, and to provide clinicians with reference for disease diagnosis and treatment.MethodThe related literatures about HBS in patients were collected and reviewed with clinical experience.ResultsHBS was a group of clinical syndromes mainly manifested as hypocalcemia after parathyroidectomy in patients with high bone turnover state before operation, with a high incidence, and the main purpose of treatment was achieved by supplementing calcium and vitamin D.ConclusionsHBS requires reasonable diagnosis and timely treatment by clinicians. Patients can achieve long-term blood calcium and phosphorus stability and bone mass growth through medical treatment.
ObjectiveTo analyze the factors influencing the hungry bone syndrome (HBS) in patients with secondary hyperparathyroidism (SHPT) after parathyroidectomy. MethodsThe clinical data of patients who underwent parathyroidectomy for SHPT in the 900th Hospital of the Joint Logistics Support Force from January 2016 to May 2021 were retrospectively analyzed. The risk factors for HBS were analyzed by binary logistic regression analysis. The cut-off value of risk factors for predicting postoperative HBS was analyzed by using recieve operating characteristic (ROC) curve. ResultsA total of 89 patients were included in this study, including 44 males and 45 females, with (47±11) years old. There were 42 (47.2%) patients with HBS. Compared with the patients without HBS, the patients with HBS was younger and had higher levels of preoperative parathyroid hormone, potassium, and alkaline phosphatase (ALP), the differences were statistically different (P<0.05). The multivariate binary logistic regression analysis showed that the higher preoperative ALP level was a risk factor for the HBS [OR (95%CI) = 1.014 (1.007, 1.020), P<0.001]. The area under the ROC curve (95%CI) of the preoperative ALP level in distinguishing the patients with HBS from without HBS was 0.957 (0.919, 0.996), and the optimal cut-off value of ALP for predicting postoperative HBS was 278.90 U/L. ConclusionsFrom the preliminary results of this study, it can be concluded that bone conversion status can be differentiated according to preoperative ALP level in patients with SHPT. When preoperative ALP level is higher than cut-off value, it is recommended that calcium supplementation should be given as soon as possible and blood calcium level should be closely monitored.
