目的观察甲状旁腺全切除(PTX)加自体前臂移植术治疗尿毒症维持性透析患者严重继发性甲状旁腺功能亢进(SHPT)的临床疗效。方法回顾性分析我院12例接受PTX加自体前臂移植术的患者资料,包括术前B超定位与手术切除的甲状旁腺定位的关系,以及术前后血甲状旁腺激素(iPTH)、血钙磷、红细胞比容(Hct)、甘油三酯、透析充分性(Kt／V、UUR)的变化。结果 11例患者术中所切除的甲状旁腺结节与术前B超定位完全一致,1例患者在手术探查中新发现1个较小的约0．5 cm3甲状旁腺结节。术后血钙、磷及其乘积较术前明显下降,差异有统计学意义。术后各时间点(1周、1、3、6、12个月)血iPTH较术前明显下降,差异有统计学意义。术后3个月甘油三酯[(1．78±0．61)mmol／L]较术前[(2．07±0．47)mmol／L]明显下降,Hct (0．31±0．06)较术前(0．26±0．05)明显提高;透析充分性Kt／V、UUR(1．668±0．173、0．696±0．041)较术前(1．567±0．195、0．667±0．054)升高,差异均有有统计学意义。结论甲状旁腺全切除加自体前臂移植能有效治疗SHPT,可以改善患者的贫血及脂质代谢紊乱,提高部分患者的透析耐受性而改善透析充分性。术前颈部甲状旁腺B超定位指导手术是可行的方法之一。避免术后复发的关键是做到真正的甲状旁腺全切除及选取适量的弥漫增生的甲状旁腺行自体前臂移植。     

Effect of parathyroidectomy on anemia and cardiac function in uremic patients with secondary hyperparathyroidism

Objective To explore the effect of total parathyroidectomy (PTX) with forearm autograft on the anemia and cardiac function in uremic patients with secondary hyperparathyroidism (SHPT). Methods The clinical data of 130 uremic patients who received PTX with forearm autograft in the First Affiliated Hospital of Zhejiang University from October 2010 to December 2015 were retrospectively analyzed. The changes of anemia and echocardiogram before and after operation were compared. According to the presence of left ventricular hypertrophy (LVH) before operation, the patients were divided into LVH group and non-LVH group. Echocardiographic indexes before and one year after operation of the two groups were compared. Results (1) Three months and one year after operation, hemoglobin and hematocrit increased while erythropoietin average usage decreased significantly (P＜0.01). (2) Compared with preoperative period, the dry weight was significantly increased one year after operation, and the cardiac function indexes including left ventricular end diastolic diameter (LVDd), interventricular septum end diastolic thickness (IVSd), left ventricular posterior wall end diastolic thickness (LVPWd), interventricular septum systolic thickness (IVSs), left ventricular systolic diameter (LVDs), left ventricular myocardial mass (LVM), and left ventricular myocardial mass index (LVMI) decreased significantly (P＜0.05). (3) In the non-LVH group, only IVSs decreased one year after operation (P＜0.05). In the LVH group, LVDs, LVDd, LVPWd, LVM, LVMI and IVSs were decreased significantly one year after operation than those in preoperative period (P＜0.05). Conclusions PTX with forearm autograft is an effective treatment for uremic patients with SHPT significantly improving anemia and left ventricular structure and function, especially for patients with ventricular hypertrophy in preoperative.

Postoperative variations of bone turnover markers in uremic patients with secondary hyperparathyroidism after parathyroidectomy

Objective To study shortdated postoperative variation characteristics of bone turnover markers (BTMs) in uremic patients with secondary hyperparathyroidism (SHPT) underwent parathyroidectomy (PTX). Methods A total of 19 uremic patients with SHPT underwent successful PTX, hospitalized in the Department of Nephrology, The First Affiliated Hospital of Nanjing Medical University from January 2017 to April 2017, were enrolled in the study. The operative model for all enrolled patients was total parathyroidectomy with forearm autotransplantation. The baseline epidemiological and clinical data before PTX and the levels of serum intact parathyroid hormone (iPTH) and serum BTMs after PTX (in the 1st, 3rd and 7th postoperative day) were collected. The correlations between serum iPTH and serum BTMs before PTX and the trend analysis of serum BTMs after PTX were studied. Results The levels of serum iPTH, serum alkaline phosphatase (ALP), serum type Ⅰcollagen cross-linked C-telopeptides (CTX) and serum tartrate-resistant acid phosphatase 5b (TRACP-5b) before PTX were increased, in turn, (1512.4±612.0) ng/L, 267.4(153.1, 424.2) U/L, (5.78±1.15) μg/L and (8.79±4.61) IU/L. Positive correlations between ALP and iPTH (r=0.577, P=0.010), TRACP-5b and iPTH (r=0.640, P=0.003), and ALP and TRACP-5b (r=0.698, P=0.001) were found. The serum levels of ALP increased, while the serum levels of CTX and TRACP-5b decreased within 7 days after PTX. Conclusions Renal osteodystrophy (ROD) with high bone turnover rate is common in uremic patients with severe SHPT. The activities of osteoblast and osteoclast are up-regulated in coupling with positive correlations to serum levels of iPTH. Increased activities of osteoblast and decreased activities of osteoclast were found shortdated postoperatively.

Effects of different treatment methods on renal anemia in maintenance hemodialysis patients with hyperparathyroidism secondary to uremia

Objective To observe the effects of three treatment methods on renal anemia in maintenance hemodialysis patients with hyperparathyroidism secondary to uremia and analyze the influencing factors of erythropoietin (EPO) dosage. Methods A total of 55 maintenance hemodialysis patients with secondary hyperparathyroidism at the hemodialysis center of Huashan Hospital affiliated to Fudan University from January 2015 to December 2016 were retrospectively divided into three groups according to different treatment methods, parathyroidectomy +forearm transplantation group (surgery group, n=16), cinacalcet treatment group (n=6), and calcitriol treatment group (n=33), respectively. The hemoglobin level and erythropoietin dosage were measured before treatment and in the 3rd month, the 6th month and the 12th month after treatment. The changes of hemoglobin and erythropoietin dosage in the three groups before and after treatment were observed, and the mixed effect model was used to analyze the difference of the change of hemoglobin and erythropoietin dosage among three groups. Multiple linear regression analysis was used to analyze the influencing factors of EPO dosage after one year. Results The levels of intact parathyroid hormone (iPTH) in the surgery group and the cinacalcet group before treatment were significantly higher than that in the calcitriol group (both P＜0.05). In the 12th month after treatment, the levels of iPTH decreased significantly in the patients of surgery group and the cinacalcet group compared with those before treatment (both P＜0.05). The levels of serum alkaline phosphatase, serum calcium and serum phosphorus in the surgery group also decreased significantly compared with those before treatment (all P＜0.05). The mixed effect model analysis showed that the hemoglobin level of surgery group was on an upward trend after the treatment, and the overall level was significantly higher than cinacalcet and calcitriol treatment group (P=0.007). There was no significant difference in the dosage change of erythropoietin (EPO) in the three groups over time. However, the intra-group comparison of the mixed effect model showed that the dosage of EPO in the 12th month was significantly lower than that of before the treatment in surgery group (P=0.007). Multiple linear regression analysis showed that dialysis vintage (B=-0.064, P=0.012) and ferritin ≥ 500 μg/L (B=0.645, P=0.032) were independent influencing factors of EPO dosage. The longer the dialysis vintage, the less EPO dosage, and more EPO dosage were observed in patients with ferritin ≥ 500 μg/L. Conclusions Parathyroidectomy and forearm transplantation is more effective in reducing EPO dosage and improving renal anemia in maintenance hemodialysis patients with secondary hyperparathyroidism. Dialysis vintage and ferritin are independent influencing factors for the dosage of EPO.     

甲状旁腺切除术用于难治性肾性继发性甲状旁腺功能亢进的安全性及近远疗效

背景与目的:甲状旁腺切除术(PTX)是治疗药物不能控制的难治性肾性继发性甲状旁腺功能亢进症(SHPT)的重要手段,但PTX术后仍有可能发生永久性甲状旁腺功能减退,无动力性骨病或难治性骨软化症,且国内尚缺乏对PTX术后远期的疗效观察的研究。本研究进一步评价PTX治疗难治性肾性SHPT的安全性与近远期疗效。方法:纳入2011年1月—2014年12月在安徽医科大学第二附属医院行PTX治疗的139例伴有难治性肾性SHPT的维持性透析患者。收集患者术前及术后3 d、6个月及1、2、3年的临床资料、血全段甲状旁腺激素(iPTH)、血钙、血磷、血红蛋白(Hb)及红细胞压积(Hct)等,观察并记录术后症状缓解情况、术后并发症和随访情况。结果:139例患者的PTX手术成功率为95.7%(133/139),术中共计切除甲状旁腺腺体537枚,平均切除3.86枚/例。12例(8.6%)术后发生一过性喉返神经损伤,其中声音嘶哑9例(6.5%),饮水呛咳3例(2.2%),未予处理术后3个月内均自行好转。术后低钙血症或缺乏维生素D者120例(86.3%),给予西那卡塞、补钙及补充活性维生素D治疗后得到有效控制。全组未发生切口感染、出血、窒息及甲状腺功能减退等外科并发症。患者的贫血状况均有不同程度地改善,Hb和Hct术后6个月明显升高并在随访期间保持稳定;术后iPTH明显降低,术后3 d的血钙、磷、钙磷乘积水平最低,随访3年仍低于手术前,所有变化与术前均有统计学差异(均P0.05)。随访期间无死亡病例。患者术前的骨痛、顽固性皮肤瘙痒、失眠、异位钙化、肌无力伴萎缩症状在术后1 d即明显缓解;身高缩短、骨骼畸形患者随访期间无进行性加重;纳差、全身营养状况及自理能力术后3个月内不同程度地改善。11例(7.9%)持续性SHPT,包括4例(2.9%)术中未完全切除甲状旁腺腺体,1例(0.7%)术中1枚腺体较小而未切除完全,6例(4.3%)术后检查存在纵隔异位甲状旁腺。随访期间,5例(3.5%)腺体未切除完全者的iPTH均800 pg/mL,肌无力及顽固性皮肤瘙痒临床症状明显,再次行PTX;6例(4.3%)存在异位甲状旁腺腺体者,因手术风险较大患者拒绝再次手术,予以药物治疗;8例(5.8%)术后复发,其中6例(4.3%)系前臂移植物复发所致,均在局麻下行前臂皮下移植物切除;2例(1.4%)系颈部原位残留腺体过度增生,予以二次手术,术后症状缓解。所有进行二次手术的患者在随访结束时无明显的临床症状,均未复发。结论:PTX可改善难治性肾性SHPT患者临床症状、贫血及钙磷代谢,且近远期疗效均较好,是治疗难治性SHPT的安全有效方法。     

Clinical characteristics of 496 secondary hyperparathyroidism patients undergoing parathyroidectomy

Objective To retrospectively analyze the characteristics of age distribution and clinical nutritional parameters in secondary hyperparathyroidism (SHPT) patients undergoing parathyroidectomy (PTX). Methods Clinical data of 496 SHPT patients undergoing PTX from 2011 to 2015 in the First Affiliated Hospital with Nanjing Medical University were collected and recorded. Age stratification of SHPT patients was observed. The levels of nutritional parameters in different age groups were compared using ANOVA analysis. The relationship between intact parathyroid hormone (iPTH) and nutritional parameters was explored using Spearman's correlation. Results There were 274 males in 496 SHPT patients who were aged (46.0±11.4) years. Chronic glomerulonephritis was the major primary cause of patients (92.1%). Their dialysis vintage was (7.7±3.6) years. The proportion of SHPT patients receiving hemodialysis was 92.9%. In SHPT patients serum levels of calcium, phosphorus, iPTH and alkaline phosphatase (ALP) were (2.6±0.2) mmol/L, (2.2±0.5) mmol/L, (2290.0±1294.2) ng/L, and (564.7±537.8) U/L, respectively. Levels of serum albumin (Alb) in all age groups were lower than the reference range. Serum calcium, ALP, and iPTH levels among age groups were different with statistical significance, while serum phosphorus levels among age groups shown no statistically significant difference. Compared with patients aged ≤18 years old and 19~30 years old, the level of ln[ALP] was lower in patients aged 61-70 years old (P＜0.05). Conclusions Severe SHPT patients are mainly receiving hemodialysis and aged between 30 and 60 years old. Chronic glomerulonephritis is a primary cause of SHPT patients. In order to increase the patients' endurance of operations and reduce the occurrence of postoperative complications, malnutrition in SHPT patients is to be alleviated before PTX.

Effect of different surgical procedures of parathyroidectomy on secondary hyperparathyroidism: a meta-analysis

Objective To evaluate the effect of total parathyroidectomy and autotransplantation (TPTX+AT) and total parathyroidectomy (TPTX) on secondary hyperparathyroidism (SHPT). Methods PubMed, EMBASE and Cochrane library were searched from inception to June 2017 for relative studies, which were screened according to inclusion criteria. Meta-analysis of included study were conducted to compare the improvement of symptoms, persistent SHPT, recurrent SHPT, reoperation, hypoparathyroidism, duration of operation and hospitalization between TPTX+AT group and TPTX group. Results A total of 11 studies with 1212 patients were included. Results of meta-analyses showed no difference between TPTX+AT and TPTX regarding improvement of symptoms and persistent SHPT (RR=1.03, P=0.70; RR=0.81, P=0.67, respectively), but TPTX was associated with lower risks of recurrent SHPT and reoperation (RR=0.25, P＜0.01; RR=0.19, P＜0.01). Patients with TPTX had higher rate of hypoparathyroidism (RR=2.68, P＜0.01) but shorter time of operation (MD=-17.3, P=0.01). Durations of hospitalization were similar between the two groups (MD=-0.06, P=0.98). Conclusion Compared with TPTX+AT, TPTX reduces the risks of recurrent SHPT, reoperation and operation time, but has higher risk of hypoparathyroidism.     

甲状旁腺切除术对血液透析患者合并继发性甲状旁腺功能亢进骨代谢及骨密度的影响

Total parathyroidectomy with forearm autograft for secondary hyperparathyroidism in chronic renal failure.

One hundred twenty-eight patients with chronic renal failure and secondary hyperparathyroidism underwent total parathyroidectomy with forearm autograft. Postoperative clinical improvement was remarkable. In all cases, the grafted tissue functioned well, and reimplantation of the cryopreserved parathyroid tissues was unnecessary. Intact 1-84 parathyroid hormone was more sensitive than C-terminal parathyroid hormone in parathyroid hormone level (PTH) gradient assays of grafted and nongrafted forearm. The study of hypocalcemia was also helpful in obtaining more distinct PTH gradients. Five of 119 patients had supernumerary parathyroid glands (4.2%), which preoperative noninvasive image diagnosis of parathyroid glands was helpful in detecting.

Correlation between pathological types of parathyroid and clinical manifestations in patients with renal secondary hyperparathyroidism

Objective To analyze the correlation between the pathological types of parathyroid and clinical manifestations in patients with renal secondary hyperparathyroidism (SHPT), so as to improve the efficacy and safety of treatment. Methods The pathological and clinical data of 130 patients with renal SHPT and maintenance hemodialysis (MHD) who had undergone total parathyroidectomy with autotransplantation (TPTX+AT) were collected. A total of 545 parathyroid glands were obtained and 998 slices were made and read. According to the pathological types of parathyroid hyperplasia, the patients were divided into diffuse hyperplasia (DH) group, diffuse between hyperplasia and nodular hyperplasia (DH/NH) group as well as nodular hyperplasia (NH) group. The clinical and biochemical characteristics of different groups before and after operation (1-, 3-, 6-, 9-, 12-month) were compared and analyzed by statistical tests. Results (1) The preoperative status: the dialysis age, serum calcium as well as incidence of bone pain, skin itching and shorten height in the NH group were significantly higher than those in the DH group (all P＜0.05), and the serum phosphorus and iPTH in the NH group were significantly higher than those in DH and DH/NH group (all P＜0.05). (2) The postoperative status: the serum calcium of the NH group at 1-month was lower than that of the DH group, and the incidence of hypocalcemia of the NH group at 1-month was higher than that of the DH group (P＜0.05); the serum phosphorus at 3-, 6-, 9-month and iPTH at 1-, 3-month of the NH group were significantly lower than that of the DH group (all P＜0.05), and the serum phosphorus at 3-month and iPTH at 1-month of the NH group were lower than that of the DH/NH group (all P＜0.05). Among the 3 groups the serum phosphorus change from 1 to 12 months had difference (F=3.241, P=0.042), while the differences of serum calcium and iPTH changes were statistically insignificant. Conclusions The clinical manifestations, serum calcium, phosphorus and iPTH in patients with renal SHPT before and after TPTX+AT are closely related to the pathological types of parathyroid hyperplasia. Compared with the DH patients, before the operation the NH patients have longer dialysis age, more serious the clinical symptoms such as bone disease, higher calcium, phosphorus and iPTH, while greater reduction of the serum calcium, phosphorus and iPTH in the short term after operation.     

16例继发性甲状旁腺功能亢进患者行甲状旁腺切除术后复发再次手术的临床分析

目的分析16例继发性甲状旁腺功能亢进(SHPT)患者行甲状旁腺切除术后复发再次手术的临床应用效果。 方法回顾性分析2017年5月至2019年10月接受再次手术的16例SHPT行甲状旁腺切除术后复发患者临床资料,采用SPSS22.0软件进行数据处理,甲状旁腺体积、实验室指标、生存质量(WHOQOL-BREF)以( ±s)表示,采用配对样本t检验;手术成功率、症状改善情况及并发症采用χ²检验,P<0.05为差异有统计学意义。 结果16例患者手术成功15例,手术成功率为93.75%;相比术前,患者术后6个月的皮肤瘙痒、骨痛、骨折或骨骼畸形、肌无力伴萎缩及异位钙化发生率较低,甲状旁腺体积、血清全段甲状旁腺激素(iPTH)、血钙(Ca)及磷(P)水平均较低,WHOQOL-BREF各维度评分均较高,差异有统计学意义(P<0.05);16例患者均未见手脚抽搐、术区出血、呼吸困难及骨饥饿综合征等并发症,5例出现低钙血症,1例出现短暂性进食呛咳。 结论针对甲状旁腺切除术后复发的SHPT再次手术治疗的成功率高、并发症少,可促进临床症状改善及消失,降低血清iPTH水平,避免遗留甲状旁腺,改善生活质量。
