BackgroundParathyroidectomy (PTX) is a treatment for hyperparathyroidism (HPT) and has uncertain risks and benefits. The aim of this study was to evaluate the effect of PTX versus nonoperative treatment among nondiabetic hemodialysis patients.MethodsA retrospective matched cohort study was performed. Each PTX patient was matched with one patient who had severe HPT but rejected PTX. The patients were matched by sex, birth date, date of first dialysis, nondiabetic status, and left ventricular ejection fraction. The serum markers, survival, main adverse cardiovascular and cerebrovascular event (MACCE) rates, and hospitalization were compared between the PTX patients and matched non-PTX patients.ResultsThere were 1143 patients at our center in the Chinese National Renal Data System (CNRDS) between 2010 and 2020. Of these, 75 PTX patients were matched with 75 non-PTX patients. Rapid decreases in the mean intact parathyroid hormone, calcium and phosphorus concentrations, and a gradual increase in hemoglobin concentration were observed in the PTX group. The mortality was 2.9 per 100 patient-years in the PTX group and 10.9 per 100 patient-years in the non-PTX group (p < 0.001). Compared with non-PTX patients, PTX patients had an adjusted HR for death of 0.236 (95% CI 0.108–0.518). The cumulative MACCE rates were 6.7 per 100 patient-years in the PTX group and 15.2 per 100 patient-years in the non-PTX group (p < 0.001). The adjusted HR of the occurrence of first MACCE for PTX patients compared with non-PTX patients was 0.524 (95% CI 0.279-0.982). The cumulative hospitalization rates were 50.3 per 100 patient-years in the PTX group and 66.5 per 100 patient-years in the matched non-PTX group (p < 0.001).ConclusionsCompared with non-PTX patients, PTX was associated with an improvement in the biochemical measures and patient-level outcomes in nondiabetic hemodialysis patients with severe HPT.  相似文献

ObjectiveHypocalcemia after parathyroidectomy (PTX) results in tetany, diarrhea, cardiac arrhythmia, and even sudden death. However, a meta-analysis or systematic evaluation of risk factors with the occurrence and development of hypocalcemia in patients with secondary hyperparathyroidism (SHPT) after PTX has never been performed.MethodsA thorough search of electronic databases, including PubMed, Web of Science, the Cochrane Library, and EMBASE, was performed to retrieve relevant studies from database inception to June 2021. Quality of the included studies was assessed by two independent reviewers using the Newcastle–Ottawa Scale. Review Manager 5.3 and Stata 16.0 were used for meta-analysis. The random-effects model was adopted to calculate the 95% CIs (I2> 50% or p < 0.05) of the combined effect size and the corresponding homogeneous data. Otherwise, a fixed-effects model was used.ResultsThirteen studies including 2990 participants who met the inclusion criteria were enrolled in the present meta-analysis. The overall quality of the enrolled studies had a score of >7 points. Risk factors significantly related to hypocalcemia in patients with SHPT after PTX were preoperative serum calcium (OR 0.19, 95%CI 0.11–0.31), preoperative alkaline phosphatase (ALP) (OR 1.01, 95% CI 1.01–1.02), and preoperative intact parathyroid hormone (iPTH) (OR 1.38, 95%CI 1.20–1.58). Meanwhile, age (OR 0.97, 95%CI 0.87–1.10) was not significantly correlated with hypocalcemia after PTX.ConclusionsBased on the current evidence, preoperative serum calcium, preoperative ALP, and preoperative iPTH were significant predictors of hypocalcemia in patients with SHPT after PTX. More attention should be given to patients with these risk factors for the prevention of postoperative hypocalcemia.  相似文献

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.  相似文献

Background: Severe hypocalcemia is the most dangerous complication occurring after total parathyroidectomy without autotransplantation (TPTX) for secondary hyperparathyroidism (SHPT). We aim to identify the prevalence and potential risk factors of very severe hypocalcemia in patients with SHPT undergoing TPTX.

Methods: From April 2012 to August 2015, 157 patients with SHPT undergoing TPTX were reviewed. The critical value of hypocalcemia (CVH) was postoperative serum Ca2+ levels of ≤1.5?mmol/L.

Results: Univariate analysis showed that patients in the CVH group were significantly younger than those in the non-CVH group. Sex ratio was significantly different between the two groups. The CVH group had significantly higher levels of preoperative PTH and ALP. Male sex and preoperative levels of PTH and ALP were significant independent risk factors by logistic regression analysis.

Conclusions: Male sex, preoperative PTH and ALP were significantly associated with CVH in patients with SHPT undergoing TPTX.  相似文献

ObjectiveTo find changes in voice quality, airway invasion during swallowing, pharyngeal residue after swallowing, acoustic and aerodynamic measurements and pulmonary function tests after total parathyroidectomy plus auto-transplantation for secondary hyperparathyroidism.MethodsWe recruited 38 patients who underwent successful surgery for secondary hyperparathyroidism in this study. Voice quality was evaluated using voice handicap index (VHI-10), eating assessment tool (EAT-10), voice impairment, and the grade, roughness, breathiness, asthenia, strain (GRBAS) scale. Acoustic and aerodynamic measurements included fundamental frequency (F0), maximal phonation time, high pitch, jitter, s/z, shimmer and noise-to-harmonic ratio. Vocal cord mobility, vocal cord closure, premature spillage, the penetration–aspiration scale and the Yale pharyngeal residue severity rating scale (PRSRS) after swallowing were examined using fiber-optic endoscopy. Pulmonary function tests included forced vital capacity, forced expiratory volume in 1 s, bronchodilator test, total lung capacity, diffusion capacity of the lung for carbon monoxide, alveolar volume, and distance and O2 desaturation of the 6 min walking test (6MWT).ResultsFour months after successful parathyroidectomy, VHI-10 improved significantly (p < 0.01); incomplete vocal cord closure decreased significantly (p < 0.01); the Yale PRSRS for vallecula and pyriform sinus improved significantly (p = 0.02 and p = 0.02); F0 and high pitch increased significantly (p < 0.01 and p = 0.01); O2 desaturation (<4%) of 6MWT improved significantly (p = 0.04).ConclusionsParathyroidectomy for secondary hyperparathyroidism can improve the voice quality, vocal cord closure, the Yale PRSRS for vallecular and pyriform sinus and O2 desaturation of 6MWT, and increase F0 and high pitch.  相似文献

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.  相似文献

Secondary hyperparathyroidism is one of the most serious complications for long-term hemodialysis patients. In our department, we performed parathyroidectomies on 215 patients between July 1973 and June 1990. We found that parathyroidectomies on 215 patients between July 1973 and June 1990. We found that parathyroidectomy was an effective treatment for advanced renal hyperparathyroidism and that after total parathyroidectomy with forearm autograft, renal hyperparathyroidism was controllable, even when hyperparathyroidism was progressive. However, the timing of this operation was important, because skeletal deformity and vessel calcification did not improve after parathyroidectomy. There were two problems after parathyroidectomy for secondary hyperparathyroidism. One was persistent hyperparathyroidism due to supernumerary parathyroid glands, particularly those located in the mediastinum, and the other was recurrent hyperparathyroidism. From our clinical and pathohistological investigations, we suspected that the proliferation of parathyroid cells changed with the progress of renal hyperparathyroidism and we found that it was difficult to prevent enlargement of parathyroid glands and recurrence of this problem.  相似文献

BACKGROUND: The Bio-Intact PTH (1-84) assay has recently been developed to specifically measure the intact PTH (1-84) molecule, and in this study we used it to investigate sequential changes in serum Bio-Intact PTH (1-84) levels during parathyroidectomy for secondary HPT. MATERIAL AND METHODS: The subjects of this study were 70 patients (41 women, 29 men) who underwent parathyroidectomy between April 2002 and March 2005. Ethylene diamine tetraacetic acid serum samples were drawn via a peripheral venous catheter after induction of anesthesia (basal), and at 5, 10, and 30 min after diseased glands excision. Serum active PTH (1-84) was measured by the Bio-Intact PTH (1-84) assay, which is a two-site chemiluminometric assay. RESULTS: When 4 or more diseased parathyroid glands were removed, the basal of Bio-Intact PTH (1-84) level in patients without persistent HPT (52 cases) was 539 +/- 355 pg/mL. The level of the Bio-Intact PTH (1-84) at 30 min after sufficient parathyroidectomy had decreased to less than 45 pg/mL, whereas the Bio-Intact PTH (1-84) level in patients with persistent HPT at 30 min was greater than 45 pg/mL (3 cases). After removal of three or fewer diseased parathyroid glands (15 cases), the Bio-Intact PTH (1-84) at 30 min in patients without persistent HPT (13 cases) was less than 45 pg/mL. The 2 patients whose the Bio-Intact PTH (1-84) at 30 min was greater than 45 pg/mL underwent reoperation, and residual enlarged parathyroid gland in the neck was removed. CONCLUSIONS: The Bio-Intact PTH (1-84) level at 30 min after parathyroidectomy seems to be useful for judging whether the parathyroidectomy is complete irrespective of the number of glands removed from patients with secondary HPT. When only three diseased parathyroid glands are removed, the surgeon can decide whether to continue or stop neck exploration according to the level of Bio-Intact PTH (1-84) at 30 min.  相似文献

IntroductionThe study objective was to evaluate the intraoperative 50% decrease in PTH level ± PTH normalization for its accuracy and efficiency in predicting cure during parathyroidectomy (PTx) for the treatment of primary hyperparathyroidism (PHP).MethodsA retrospective review of patients undergoing PTx was conducted. The timepoints at which the 50% PTH decrease was reached were recorded. The accuracy of intraoperative PTH for predicting cure, defined as normocalcemia at 6 months postoperatively, was evaluated.ResultsThe study population was made up of 248 PHP patients, with 247 patients achieving normocalcemia at 6 months postoperatively. If a 50% PTH decrease was used to indicate operation conclusion, 1 patient would not be cured. Persistent PTH elevation above normal range at T10 had a PPV of 77%, NPV of 99.5%, sensitivity of 95.2% and specificity of 97.3% for predicting the presence of a contralateral pathological parathyroid gland. For the study cohort, 24.5 h of cumulative operating time would be saved if the 50% PTH decrease triggered operation conclusion.DiscussionA decrease in the pre-excision PTH level to 50% of the baseline level, or a decrease in the higher of the baseline or pre-excision PTH levels by 50% at 5 or 10 min post pathological parathyroid gland removal, regardless of whether the PTH level normalizes, reliably predicts cure from PHP and should be used to guide the surgeon during parathyroidectomy.  相似文献

ObjectiveTo evaluate parathyroidectomy for primary hyperparathyroidism (PHPT) regarding localization, surgical characteristics, and treatment outcomes.MethodsSeventy-eight patients who underwent parathyroidectomy for PHPT were retrospectively reviewed. The results were analyzed according to intraoperative localization technique (IOLT), intraoperative parathyroid hormone (IOPTH) monitoring, and intraoperative nerve monitoring (IONM). The localization accuracy of ultrasonography (US), computed tomography (CT), and single-photon emission computed tomography (SPECT)-CT with sestamibi Tc99m was evaluated.ResultsParathyroidectomy was successfully completed in all 78 patients, achieving 100% surgical cure. For 60 patients with IOPTH monitoring, 10-min IOPTH decreased >50% from baseline in 57 (95.0%), and they achieved surgical cure. In the remaining three (5.0%) patients with ≤50% decrease in 10-min IOPTH, 20-min IOPTH decreased >50% from baseline in two (3.3%) patients, achieving surgical cure without additional neck exploration. There were no differences in surgical cure and complications as a function of IOLT use or IOPTH monitoring. Operating time was significantly shorter with IOLT and IOPTH monitoring than without (IOLT: 70.9 min vs. 88.0 min, p = 0.013; IOPTH: 74.9 min vs. 91.9 min, p = 0.037). All 78 patients had adenoma including one patient with a double adenoma. Vocal cord paralysis was not observed in our series, regardless of IONM. US, CT, and SPECT-CT localized the pathological parathyroid gland accurately in 88.1%, 85.5%, and 86.8% of patients, respectively (p = 0.894).ConclusionThe surgical outcomes of parathyroidectomy for PHPT were excellent regardless of IOLT and IOPTH monitoring. However, these techniques can maximize the performance of parathyroid surgery by reducing operating time and rescuing challenging cases.  相似文献

Objective To analyze the efficacy and safety of total parathyroidectomy (PTX) with forearm autograft in uremic patients with secondary hyperparathyroidism (SHPT). Methods One hundred and eighteen cases undergoing PTX with forearm autograft in our hospital from 2001-2010 were included in this study. Their preoperative and postoperative serum intact parathyroid hormone (iPTH), biochemistry tests (total calcium,inorganic phosphate and alkaline phosphate) were collected and postoperative symptom relief, complications and recurrence were investigated. Results Of all the 118 cases, 32 underwent endoscopic surgery and 86 open surgery. The surgery was performed successfully in 110 cases (93.2%) and one case died in perioperative period. Thyroid carcinoma was diagnosed during surgery in 2 cases and radical operation was performed at the same time. Temporary injury of recurrent laryngeal nerve was found in nine cases (7.6%). Postoperative hypocalcemia was frequently seen in 108 cases (91.5%) and it was effectively controlled by postoperative calcium administration. After operation, bone pain and itching were alleviated, and weakness, anemia and malnutrition status were improved in all the cases who received successful surgery. The postoperative levels of serum iPTH (P<0.01), calcium (P<0.01), phosphorus (P<0.01) and calcium×phosphorus (P<0.01) were decreased significantly than those in preoperative period. A long-term follow-up of over 3 years was carried out in 21 cases. Six cases recurred, among them, 4 cases relieved after removal of autografted parethroid tissue, and another two cases received the second operation. The longest follow-up period lasted for 9 years in two cases without recurrence. Conclusions PTX with forearm autograft is safe and effective in the treatment for uremic patients with SHPT. No severe complication is found during the long-term follow-up period.  相似文献

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.  相似文献
