RESUMO

Purpose: Population-based and registry studies have shown that chronic hypoparathyroidism is accompanied by long-term complications. We aimed to evaluate the risk of incident comorbidity among patients with chronic postsurgical hypoparathyroidism in real-life clinical practice in Spain. Methods: We performed a multicenter, retrospective cohort study including patients with chronic postsurgical hypoparathyroidism lasting ≥3 years with at least a follow-up visit between January 1, 2022 and September 15, 2023 (group H). The prevalence and incidence of chronic complications including chronic kidney disease, nephrolithiasis/nephrocalcinosis, hypertension, dyslipidemia, diabetes, cardiovascular disease, central nervous system disease, mental health disorders, eye disorders, bone mineral density alterations, fracture and cancer were evaluated. Patient data were compared with a group of patients who did not develop hypoparathyroidism, matched by gender, age, and follow-up time after thyroidectomy (group NH). Results: We included 337 patients in group H (median [IQR] age, 45 [36-56] years; median time of follow-up, 8.9 [6.0-13.0] years; women, 84.3%) and 669 in group NH (median age, 47 [37-55] years; median time of follow-up, 8.0 [5.3-12.0] years; women, 84.9%). No significant differences were found in the prevalence of comorbidities at the time of thyroidectomy between both groups. In multivariable adjusted analysis, patients with chronic hypoparathyroidism had significantly higher risk of incident chronic kidney disease (OR, 3.45; 95% CI, 1.72-6.91; P<0.001), nephrolithiasis (OR, 3.34; 95% CI, 1.55-7.22; P=0.002), and cardiovascular disease (OR, 2.03; 95% CI, 1.14-3.60; P=0.016), compared with patients without hypoparathyroidism. On the contrary, the risk of fracture was decreased in patients with hypoparathyroidism (OR, 0.09; 95% CI, 0.01-0.70; P=0.021). Conclusion: This study demonstrates that, in the clinical practice of Spanish endocrinologists, a significant increase in the risk of chronic kidney disease, nephrolithiasis and cardiovascular disease, as well as a reduction in the risk of fractures is detected. These results are of interest for the development of new clinical guidelines and monitoring protocols for patients with hypoparathyroidism.

RESUMO

PURPOSE: The purpose of this study was to investigate the impact of autofluorescence technology on postoperative parathyroid function and short-term outcomes in patients undergoing thyroid surgery. METHODS: A total of 546 patients were included in the study, with 287 in the conventional treatment group and 259 in the autofluorescence group. Both groups underwent central lymph node dissection, which is known to affect parathyroid function. Short-term outcomes, including rates of postoperative hypocalcemia and parathyroid dysfunction, serum calcium and PTH levels on the first postoperative day, as well as the need for calcium supplementation, were analyzed. A multivariable analysis was also conducted to assess the impact of autofluorescence on postoperative parathyroid dysfunction, considering factors such as age, BMI, and preoperative calcium levels. RESULTS: The autofluorescence group demonstrated significantly lower rates of postoperative hypocalcemia and parathyroid dysfunction compared to the conventional treatment group. The autofluorescence group also had better serum calcium and PTH levels on the first postoperative day, and a reduced need for calcium supplementation. Surprisingly, the use of autofluorescence technology did not prolong surgical time; instead, it led to a shorter hospitalization duration. The multivariable analysis showed that autofluorescence significantly reduced the risk of postoperative parathyroid dysfunction, while factors such as age, BMI, and preoperative calcium levels did not show a significant correlation. CONCLUSION: This study provides evidence that autofluorescence technology can improve the preservation of parathyroid function during thyroid surgery, leading to better short-term outcomes and reduced postoperative complications. The findings highlight the potential of autofluorescence as a valuable tool in the management of parathyroid hypofunction. Further research and validation are needed to establish the routine use of autofluorescence technology in the thyroid.

RESUMO

Sanjad Sakati Syndrome (SSS) is categorized as a neuroendocrine-related disease due to disorders of the nervous and hormonal systems. Since hormonal changes in these patients may affect the nature and function of the immune system. Thus, in this study, cell count and phagocytotic function of neutrophils were evaluated which may be influenced by changes in the hormonal rate and growth factors. In this study, the neutrophil count value and the oxidative burst were evaluated in six patients diagnosed with SSS and six healthy individuals. There was a significant reduction in the neutrophil count observed in SSS patients compared to healthy controls (37.41±7.93 percent vs. 66.5±6.8 percent). However, there was no significant difference in neutrophil oxidative index between patients with SSS and control subjects (172.33±55.08 vs. 217.00±77.38). We concluded that in patients with SSS, the phagocytic activity of neutrophils was not affected by hormonal changes, while the number of neutrophils and neutrophil-to-lymphocyte ratio (NLR) index were decreased.

RESUMO

Minimally invasive thyroidectomy (MIT) is increasingly being used for the thyroid tumors. The comparison of bilateral axillo-breast approach robotic thyroidectomy (BABART) with other MIT has not yet led to a unified conclusion with regard to surgical outcomes. To conduct a systematic review and meta-analysis of the literature on the surgical outcomes of BABART compared with MIT. We performed a systematic search in PubMed, Web of Science, Embase and Cochrane Library database for randomized control trials (RCTs) and non-RCTs that compare BABART to MIT. The primary outcomes included perioperative, postoperative complications. The odds ratio (OR) and mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CIs). Nine studies, comprising 3645 patients, were included in the meta-analysis. Our findings indicated that there were no significant differences in hospital stay, number of retrieved lymph nodes, recurrent laryngeal nerve (RLN) injury, and vocal cord dysfunction between BABRT and MIT. However, BABART was associated with a shorter operation time (MD = - 21.45 min, 95% CI [- 47.27, 4.38], p = 0.1) and lower rate of permanent hypoparathyroidism (OR = 0.42, 95% CI [0.20, 0.88], p = 0.02). Additionally, the MIT group had reduced postoperative pain score (MD = 0.45, 95% CI [0.02, 0.88], p = 0.04) and lower rate of hypocalcemia (OR = 2.31, 95% CI [1.04, 5.13], p = 0.04) than the BABART group. In comparison with MIT, BABART exhibits better results in terms of operative time and the rate of permanent hypoparathyroidism, with no significant difference in hospital stay, number of retrieved lymph nodes, RLN injury, and vocal cord dysfunction. However, the postoperative pain score and the rate of hypocalcemia of MIT are slightly better that of BABART.

RESUMO

Magnesium is essential for the functioning and release of parathyroid hormone. Therefore, its deficiency can present as functional hypoparathyroidism. This case report describes a rare inherited disorder called congenital hypomagnesaemia with secondary hypocalcaemia due to TRPM6 gene mutation. This disease clinically and biochemically mimics hypoparathyroidism. However, unlike hypoparathyroidism, it can be treated only by long-term oral magnesium supplements. The patient presented to us with recurrent hypocalcaemic convulsions. The laboratory picture in each admission was similar to that of hypoparathyroidism. However, the hypocalcaemia persisted, and it was noticed to be associated with persistent hypomagnesaemia. A defect in the tubular magnesium reabsorption was postulated and a genetic analysis of the patient was done, which revealed a TRPM6 mutation causing hypomagnesaemia by excessive renal excretion of magnesium. The child responded well to oral magnesium supplements and is currently developmentally appropriate for her age and thriving well.

RESUMO

The sequential effects of romosozumab and denosumab in osteoporosis are shown in real-life, while the mechanisms of post-denosumab rebound are reviewed extensively. A network meta-analysis confirms the superiority of anabolics vs anti-resorptives on fracture reduction, while the latter shown a reduction of mortality in a large population-based study. Fracture risk prediction by FRAXPlus is improved. New meta-analyses confirm the benefits of Vitamin D on fractures and falls. Finally, multiples trials with new molecules for the treatment of rare bone diseases, including osteogenesis imperfecta, fibrous dysplasia and hypoparathyroidism, shown promising results.


Dans l'ostéoporose, les effets séquentiels du romosozumab et du dénosumab se précisent et les mécanismes du rebond à l'arrêt de ce dernier font l'objet d'une revue détaillée. Une méta-analyse en réseau confirme la supériorité des traitements anaboliques sur les antirésorbtifs, alors que l'effet de ces derniers sur la réduction de la mortalité est démontré dans une large étude populationnelle. La prédiction du risque fracturaire est améliorée par l'outil FRAXPlus. De nouvelles méta-analyses des bénéfices de la vitamine D sur le risque de fractures et de chutes sont également disponibles. Enfin, de nombreuses études encourageantes sur l'efficacité de nouveaux traitements dans de multiples maladies osseuse rares, telles l'ostéogenèse imparfaite, la dysplasie fibreuse et l'hypoparathyroïdie, ont été publiées.

RESUMO

Background: Hypoparathyroidism following total thyroidectomy is globally the most common complication to thyroid surgery. The reported complication rates vary widely and might be highly dependent on the surgical experience. In this study we aimed to evaluate the rate of hypoparathyroidism following primary total thyroidectomy at a low-volume institution that only performs thyroid surgery and does not have any experience with parathyroid surgery. Methods: Retrospective cohort study. All patients undergoing primary total thyroidectomy at the ENT-Department, Goedstrup Hospital, Denmark, over a 5-year period (2016-2020) were identified through the procedure codes for total thyroidectomy. Medical records, pathology reports, biochemical and medical histories were fully assessed for each patient. The primary endpoint was the rate of hypoparathyroidism- both immediate and permanent. Secondary outcomes were parathyroid gland identification rates, rates of parathyroid gland autotransplantation, and rates of inadvertent parathyroid gland excision. Results: A total of 89 patients were included in the final analysis. A total of 33 patients (37.1%) experienced immediate hypoparathyroidism following surgery, while 30 patients (33.7%) still were on active vitamin D two months postoperatively. One year following surgery, 28 patients (31.5%) were still on active vitamin D and were considered as having permanent hypoparathyroidism. Sixty-one percent of the parathyroid glands were identified intraoperatively, and 19% of the patients experienced parathyroid autotransplantation. Inadvertent parathyroid gland excision occurred for 21% of the patients and was associated with a significantly increased risk of permanent hypoparathyroidism (RR = 2.99; 95% CI: 1.36 - 6.62, p = 0.005). Conclusion: Both transient and permanent hypoparathyroidism following total thyroidectomy at a low-volume, non-parathyroid institution occurred with much higher frequencies than previously reported. The elevated rates were most likely due to the low-volume, non-parathyroid nature of the surgeons which in part was mirrored in low parathyroid gland identifications rates, and high rates of autotransplantation and inadvertent parathyroid gland excision.

RESUMO

OBJECTIVE: Total thyroidectomy (TT) carries a risk of hypoparathyroidism (hypoPT). Recently, hypoPT has been associated with higher overall mortality rates. We aimed to evaluate the frequency of hypoPT and mortality in patients undergoing TT in Denmark covering 20 years. DESIGN: Retrospective Cohort study. PATIENTS AND MEASUREMENTS: Using population-based registries, we identified all Danish individuals who had undergone TT between January 1998 and December 2017. We included a comparison cohort by randomly selecting 10 citizens for each patient, matched on sex and birth year. HypoPT was defined as treatment with active vitamin D after 12 months postoperatively. We used cumulative incidence to calculate risks and Cox regression to compare the rate of mortality between patients and the comparison cohort. We evaluated patients in different comorbidity groups using the Charlson Comorbidity Index and by different indications for surgery. RESULTS: 7912 patients underwent TT in the period. The prevalence of hypoPT in the study period was 16.6%, 12 months postoperatively. After adjusting for potential confounders the risk of death due to any causes (hazard ratio; 95% confidence intervals) following TT was significantly increased (1.34; 1.15-1.56) for patients who developed hypoPT. However, subgroup analysis revealed mortality was only increased in malignancy cases (2.48; 1.99-3.10) whereas mortality was not increased when surgery was due to benign indications such as goitre (0.88; 0.68-1.15) or thyrotoxicosis (0.86; 0.57-1.28). CONCLUSIONS: The use of active vitamin D for hypoPT was prevalent one year after TT. Patients with hypoPT did not have an increased risk of mortality following TT unless the indication was due to malignancy.

RESUMO

BACKGROUND: Patients with thyroid carcinoma often undergo cervical lymph node dissection, which is associated with high rates of both transient and permanent postoperative hypoparathyroidism. The impact of near-infrared fluorescence imaging + indocyanine green (ICG) fluorescence on postoperative hypoparathyroidism rates after total thyroidectomy and central neck lymph node dissection was evaluated. METHODS: All patients undergoing surgery between January 2019 and March 2023 were included and divided into three groups: a control group (parathyroid glands identified visually), a near-infrared fluorescence imaging alone group, and a near-infrared fluorescence imaging + ICG fluorescence group. The primary outcome was the transient and permanent postoperative hypoparathyroidism rates. Secondary outcomes were: length of surgery and number of parathyroid glands identified, inadvertently resected, and autotransplanted. RESULTS: A total of 131 patients were included in the study (47 in the control group, 45 in the near-infrared fluorescence imaging alone group, and 39 in the near-infrared fluorescence imaging + ICG fluorescence group). The transient hypoparathyroidism rate was 48.9% in the control group, 37.8% in the near-infrared fluorescence imaging alone, and 5.1% in the near-infrared fluorescence imaging + ICG fluorescence group (P < 0.0001), while the permanent hypoparathyroidism rate was 8.5% in the control group, 2.2% in the near-infrared fluorescence imaging alone group, and 0% in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.096). The number of parathyroid glands identified was 159 of 188 in the control group, 165 of 180 in the near-infrared fluorescence imaging alone group, and 149 of 156 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.002). Inadvertent resection of parathyroid glands occurred for 29 of 188 in the control group, 15 of 180 in the near-infrared fluorescence imaging alone group, and 7 of 156 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.002), with subsequent parathyroid gland autotransplantation for 2 of 29 in the control group, 2 of 15 in the near-infrared fluorescence imaging alone group, and 3 of 7 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.040). There was no difference in the median operating time between groups. CONCLUSION: The use of near-infrared fluorescence imaging + ICG fluorescence decreased both transient and permanent hypoparathyroidism rates in patients undergoing total thyroidectomy and central neck lymph node dissection.

RESUMO

PURPOSE: To assess the impact of fine-needle aspiration cytology (FNAC) in the extent of surgery in patients with thyroid cancer (TC) and the associated surgical morbidity in primary and completion setting. METHODS: A Swedish nationwide cohort of patients having surgery for TC (n = 2519) from the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal surgery between 2004 and 2013 was obtained. Data was validated through scrutinizing FNAC and histology reports. RESULTS: Among the 2519 cases operated for TC, the diagnosis was substantiated and validated through the histology report in 2332 cases (92.6%). Among these, 1679 patients (72%) were female, and the median age at TC diagnosis was 52.3 years (range 18-94.6). Less than total thyroidectomy (LTT) was undertaken in 944 whereas total thyroidectomy (TT) in 1388 cases. The intermediate FNAC categories of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/ FLUS), as well as suspicion for follicular neoplasm (SFN) lesions were more often encountered in LTT (n = 314, 33.3%) than TT (n = 63, 4.6%), whereas FNACs suspicion for malignancy and/or malignancy were overrepresented in TT (n = 963, 69.4%). Completion thyroidectomies were undertaken in 553 patients out of 944 that initially had LTT. In 201 cases with cancer lesions > 1 cm, other than FTC (Follicular TC)/ HTC (Hürthle cell TC) subjected to primary LTT, inadequate procedures were undertaken in 81 due to absent, Bethesda I or II FNAC categories, preoperatively. Complications at completion of surgery in this particular setting were 0.5% for RLN palsy (n = 1) and 1% (n = 2) for hypoparathyroidism 6 months postoperatively. The overall postoperative complication rate was higher in primary TT vs. LTT for RLN palsy (4.8% [n = 67] vs. 2.4% [n = 23]; p = 0.003) and permanent hypoparathyroidism (6.8% [n = 95] vs. 0.8% [n = 8]; p < 0.0001). CONCLUSIONS: FNAC results appear to affect surgical planning in TC as intermediate FNAC categories lead more often to LTT. Overall, inadequate procedures necessitating completion surgery are encountered in up to 15% of TC patients subjected to LTT due to absent, inconclusive, or misleading FNAC, preoperatively. However, completion of thyroidectomy in this setting did not yield significant surgical morbidity. Primary LTT is a safer primary approach compared to TT in respect of RLN palsy and permanent hypoparathyroidism complication rates; therefore, primary TT should probably be reserved for lesions > 1 cm or even larger with suspicion for malignancy or malignant FNAC.

RESUMO

BACKGROUND: Hypoparathyroidism is a relatively rare endocrine disorder defined as inadequate parathyroid hormone (PTH) secretion leading to a clinical syndrome characterized by hyperphosphatemia and hypocalcemia. This condition has high morbidity; patients present with a heterogeneous range of emotional, mental, and physical symptoms. We present our experience with PTH transplantation, using parathyroid glands surgically removed in the setting of secondary hyperparathyroidism, with a description of the clinical course, immunosuppressive management, and surgical technique. METHODS: Between 2017 and 2021, 3 patients underwent parathyroid allotransplantation at the University of Illinois at Chicago. The 2 outcomes of interest were (1) symptomatic relief and improvement in calcium levels and (2) time to graft failure, defined as the presence of undetectable PTH levels. RESULTS: All 3 patients experienced dramatic improvement in their debilitating symptoms, even though 2 patients required repeated PTH transplantation procedures. One patient had a remarkable course with symptom resolution, normalization of PTH levels, and a great reduction in calcium supplementation. CONCLUSION: The use of hyperplastic glands from patients with secondary hyperparathyroidism undergoing 4-gland parathyroidectomy with autotransplantation represents an important source. However, a uniform definition of graft viability and prospective studies with long follow-ups are needed to address how much parathyroid tissue is optimally transplanted and the need for immunosuppression. Most patients affected by hypoparathyroidism are successfully managed by medical treatment; however, some do not respond to therapy and present debilitating symptoms related to hypocalcemia. This subgroup may benefit from parathyroid allotransplantation. Our 3 patients had remarkable improvement in their symptoms with the adoption of hyperplastic glands. Two out of 3 patients required multiple procedures to sustain symptom control.

RESUMO

BACKGROUND: Emerging remote-access surgical methods are utilized to treat differentiated thyroid cancer. The study aimed to compare the surgical integrity, safety, efficacy, and postoperative experience of patients among common surgical methods. METHODS: The PubMed, Medline, Cochrane Library, Web of Science, and EMBASE databases were searched from their inception until March 2023. Pairwise meta-analysis and Bayesian network meta-analysis were performed. The surface under the cumulative ranking curve (SUCRA) was used to illuminate the probability that each method would be the best for each outcome. RESULTS: Thirty-two studies comprising 7042 patients were included. Robotic bilateral axillo-breast approach (RBABA) and robotic gasless transaxillary approach (RGAA) retrieved fewer lymph nodes (LNs) than open thyroidectomy (OT). RBABA showed a significantly lower permanent recurrent laryngeal nerve (RLN) palsy rate than OT. According to SUCRA values, endoscopic transoral approach (EOA) ranked the highest in retrieved LNs (0.84), the proportion of stimulated serum thyroglobulin less than 1.0 ng/ml (0.77), and the pain score (0.77). Endoscopic bilateral areola approach (EBAA) ranked the highest in the transient RLN palsy rate (0.72). The endoscopic gasless transaxillary approach (EGAA) ranked the highest in the transient hypoparathyroidism rate (0.78). RBABA ranked the highest in the rate of permanent RLN palsy (0.94) and hypoparathyroidism (0.77). OT ranked the highest in operative time (0.92). CONCLUSIONS: Each surgical method of total thyroidectomy has benefits and limitations. EOA performed the best in maintaining surgical integrality and reducing the pain score, while taking a long operative time. Generally, RBABA showed the best advantage in protecting parathyroid glands and RLN but with the longest operative time. OT had the best advantage in operative time. Therefore, OT and EOA are ideal methods for patients with a higher risk of central LN metastasis. RBABA and EOA may not be suitable for elderly patients or those with high anesthesia risk.

RESUMO

INTRODUCTION: Thyroidectomy provides definitive treatment for autoimmune thyroid disease (AITD) often resulting in improved quality of life. Historically, patients with AITD undergoing thyroidectomy have increased rates of postoperative hypoparathyroidism and recurrent laryngeal nerve palsy. We investigated the outcomes of preoperative medications in patients with AITD undergoing thyroidectomy. METHODS: We performed a retrospective analysis of patients who underwent thyroidectomy for AITD at a single institution from 2015 to 2021. Surgical outcomes and perioperative laboratory values were analyzed by type of AITD and type of preoperative medical treatment: none, saturated solution of potassium iodide (SSKI), corticosteroids, or both SSKI and corticosteroids. RESULTS: A total of 123 patients underwent thyroidectomy for AITD and were included in analysis: 50 received no preoperative medications, 40 received SSKI, 20 received corticosteroids, and 13 received both. Seventy-six patients had Graves' disease and 47 had Hashimoto's thyroiditis. There were no significant differences in blood loss, operative time, wound complications, hematoma, or recurrent laryngeal nerve injury for patients treated with preoperative corticosteroids compared to those who were not. Patients who received corticosteroids and patients with Graves' disease more commonly had at least one instance of hypocalcemia postoperatively (P < 0.01, P = 0.01), although only on postoperative day 1 was mean calcium < 8.5 mg/dL. There was no difference in rate of transient or permanent hypoparathyroidism. CONCLUSIONS: Patients who received corticosteroids preoperatively had no increased risk of complications. They did have mildly lower calcium levels in the early postoperative period, although no difference in hypoparathyroidism. Further exploration is warranted to investigate the impact of preoperative corticosteroids on operative difficulty, quality of life, and autoantibody clearance.

RESUMO

BACKGROUND: Total pharyngolaryngectomy (TPL) is standard treatment for hypopharyngeal cancer. However, extensive thyroidectomy and paratracheal nodal dissection (PTND) can cause hypoparathyroidism. We sought to determine the optimum extent of resection. METHODS: We analyzed the clinicopathological information of 161 pyriform sinus cancer patients undergoing TPL from 25 Japanese institutions. Rates of recurrence and risk factors for hypoparathyroidism, as well as incidence of pathological contralateral level VI nodal metastasis and stomal recurrence, were investigated. RESULTS: The extent of thyroidectomy and nodal dissection were not independent risk factors for recurrence. Incidences of contralateral level VI nodal involvement and stomal recurrence were 1.8% and 1.2%, respectively. Patients undergoing hemithyroidectomy/ipsilateral PTND did not develop stomal recurrence and had the lowest incidence of hypoparathyroidism. Prognosis in patients without tracheostomy prior to hemithyroidectomy/ipsilateral PTND was comparable to that with more extensive resections. CONCLUSIONS: Hemithyroidectomy/ipsilateral PTND may be sufficient for pyriform sinus cancer cases without tracheostomy.

RESUMO

BACKGROUND: A previous nationwide study from Sweden showed that the rate of permanent hypoparathyroidism is high and under-rated in the Swedish Quality Register. This retrospective population-based study aimed to validate the rate and diagnosis of permanent hypoparathyroidism found in the previous study. A secondary aim was to assess the relationship between the rate of low parathyroid hormone (PTH) levels within 24 h after surgery and the rate of permanent hypoparathyroidism. METHODS: All patients who underwent total thyroidectomy from 2005 to 2015 in a region of Sweden were included. Data were retrieved from local health records, the National Patient Registry, the Swedish Prescribed Drug Registry, and the Swedish Quality Register. A strict definition of permanent hypoparathyroidism was used, including biochemical data and attempts to stop the treatment. RESULTS: A total of 1636 patients were included. Altogether, 143 patients (8.7 per cent) developed permanent hypoparathyroidism. Of these, 102 (6.2 per cent) had definitive permanent hypoparathyroidism, whereas 41 (2.5 per cent) had possible permanent hypoparathyroidism, because attempts to stop the treatment were lacking (28) or patients were lost to follow-up (13). The agreement between the Swedish Quality Register and the chart review was 29.3 per cent. A proportion of 23.2 per cent with a PTH level below the reference value corresponded to a 6.7 per cent rate of permanent hypoparathyroidism. CONCLUSION: The risk of permanent hypoparathyroidism after total thyroidectomy is high. Some patients are overtreated because attempts to stop the treatment are lacking. Quality registers might underestimate the risk of permanent hypoparathyroidism. Approximately one-quarter of all patients with low PTH levels immediately after surgery developed permanent hypoparathyroidism.


The parathyroid glands control calcium levels in the blood. If they do not make enough hormone, calcium levels are low. Parathyroid dysfunction can happen after thyroid surgery, if the glands are hurt or removed by mistake. This is a problem because people with this condition may have symptoms and need ongoing treatment with vitamin D and calcium. They might also face other health issues and need regular visits to their doctor. Finding out how often long-term parathyroid dysfunction happens can be tricky because it requires a full year of follow-up and attempts to stop the treatment. This information is often missing from many studies and registers. Some recent studies have shown that this condition is more common than previously thought. It would be helpful to have a quick way to know how common long-term parathyroid gland dysfunction will be within a unit or hospital, without having to wait for the follow-up. This would help doctors to assess how good they are at taking care of patients. It would also support research on new methods to avoid parathyroid dysfunction. The goal of the study was to see how often long-term parathyroid dysfunction occurs after thyroid surgery, using a strict definition and complete long-term follow-up. Another aim was to assess the link between low parathyroid hormone levels right after surgery and the rate of long-term parathyroid dysfunction. All individuals who had the entire thyroid gland removed for benign disease between 2005 and 2015 in a region of Sweden were included. Data were collected from local health records at six hospitals. Patient information, surgical details, blood tests, and treatment details were gathered from the medical charts. Data were also collected from the national quality register. A high rate of long-term parathyroid dysfunction was seen in this large study of 1636 patients, Some patients may have been overtreated, because no attempts had been made to stop the treatment. The rate of long-term parathyroid dysfunction in patients with a normal early parathyroid hormone level was very low. About 23 per cent of all patients had a low early parathyroid hormone level, which corresponded to a 6.7 per cent rate of long-term parathyroid dysfunction. The authors believe that parathyroid hormone measurement could help predict the rate of permanent hypoparathyroidism, but more studies are needed to be sure.

RESUMO

OBJECTIVE: The aim of this Meta-analysis is to evaluate the impact of different treatment strategies for early postoperative hypoparathyroidism on hypocalcemia-related complications and long-term hypoparathyroidism. DATA SOURCES: Embase.com, MEDLINE, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, and the top 100 references of Google Scholar were searched to September 20, 2022. REVIEW METHODS: Articles reporting on adult patients who underwent total thyroidectomy which specified a treatment strategy for postthyroidectomy hypoparathyroidism were included. Random effect models were applied to obtain pooled proportions and 95% confidence intervals. Primary outcome was the occurrence of major hypocalcemia-related complications. Secondary outcome was long-term hypoparathyroidism. RESULTS: Sixty-six studies comprising 67 treatment protocols and 51,096 patients were included in this Meta-analysis. In 8 protocols (3806 patients), routine calcium and/or active vitamin D medication was given to all patients directly after thyroidectomy. In 49 protocols (44,012 patients), calcium and/or active vitamin D medication was only given to patients with biochemically proven postthyroidectomy hypoparathyroidism. In 10 protocols (3278 patients), calcium and/or active vitamin D supplementation was only initiated in case of clinical symptoms of hypocalcemia. No patient had a major complication due to postoperative hypocalcemia. The pooled proportion of long-term hypoparathyroidism was 2.4% (95% confidence interval, 1.9-3.0). There was no significant difference in the incidence of long-term hypoparathyroidism between the 3 supplementation groups. CONCLUSIONS: All treatment strategies for postoperative hypocalcemia prevent major complications of hypocalcemia. The early postoperative treatment protocol for postthyroidectomy hypoparathyroidism does not seem to influence recovery of parathyroid function in the long term.

RESUMO

BACKGROUND: There is ongoing debate about whether intraoperative parathyroid autotransplantation effectively prevents permanent hypoparathyroidism after thyroidectomy. This study aims to examine its impact on postoperative parathyroid function and determine the best autotransplantation strategy. METHODS: A retrospective analysis was conducted on 194 patients who underwent total thyroidectomy with central lymph node dissection (CLND) for papillary thyroid carcinoma (PTC). Patients were divided into four groups based on the number of parathyroid autotransplants during surgery: Group 1 (none, n = 43), Group 2 (1 transplant, n = 60), Group 3 (2 transplants, n = 67), and Group 4 (3 transplants, n = 24). Various clinical parameters were collected and compared among the groups. RESULTS: Parathyroid autotransplantation was identified as a risk factor for temporary hypoparathyroidism (OR: 1.74; 95% CI: 1.27-2.39, P = 0.001) and a protective factor for permanent hypoparathyroidism (OR: 0.27; 95% CI: 0.14-0.55, P < 0.001). At 12 months postoperative, systemic parathyroid hormone (PTH) levels increased progressively from Groups 1 to 4, with significant differences observed only between Group 1 and Group 2 (P < 0.02). Difference values in systemic PTH levels between Month 1 and Day 1 postoperative increased progressively from Groups 1 to 4, with statistically significant differences observed between adjacent groups (P < 0.02). The number of dissected positive lymph nodes increased progressively across the four groups, showing statistical differences (P < 0.02). CONCLUSION: Parathyroid autotransplantation can prevent permanent hypoparathyroidism. Additionally, we recommend preserving parathyroids in situ whenever possible. If autotransplantation is required, it should involve no more than two glands.

RESUMO

ATP2B1 encodes plasma membrane calcium-transporting-ATPase1 and plays an essential role in maintaining intracellular calcium homeostasis that regulates diverse signaling pathways. Heterozygous de novo missense and truncating ATP2B1 variants are associated with a neurodevelopmental phenotype of variable expressivity. We describe a proband with distinctive craniofacial gestalt, Pierre-Robin sequence, neurodevelopmental and growth deficit, periventricular heterotopia, brachymesophalangy, cutaneous syndactyly, and persistent hypocalcemia from primary hypoparathyroidism. Proband-parent trio exome sequencing identified compound heterozygous ATP2B1 variants: a maternally inherited splice-site (c.3060+2 T > G) and paternally inherited missense c.2938 G > T; p.(Val980Leu). Reverse-transcription-PCR on the proband's fibroblast-derived mRNA showed aberrantly spliced ATP2B1 transcripts targeted for nonsense-mediated decay. All correctly-spliced ATP2B1 mRNA encoding p.(Val980Leu) functionally causes decreased cellular Ca2+ extrusion. Immunoblotting showed reduced fibroblast ATP2B1. We conclude that biallelic ATP2B1 variants are the likely cause of the proband's phenotype, strengthening the association of ATP2B1 as a neurodevelopmental gene and expanding the phenotypic characterization of a biallelic loss-of-function genotype.

RESUMO

PURPOSE: Patients with hypoparathyroidism (hypoPT) have low bone turnover and high bone mineral density (BMD). However, data on fracture risk are conflicting. The objectives of this study were: 1. To describe clinical/biochemical characteristics of hypoPT patients followed at a single medical center. 2. To identify postsurgical hypoPT patients and investigate their fracture rate compared with gender/age-matched post-surgical normocalcemic patients. METHODS: Retrospective analysis of patient's medical records treated at the tertiary medical center in 2010-2021 identified by computerized medical database search. RESULTS: The cohort included 133 patients (91% women, mean age 64 ± 13 years) of whom 105 (79%) had post-thyroidectomy hypoparathyroidism and the remainder had an autoimmune/idiopathic/other etiology. Mean follow-up time was 21 ± 12 and 27 ± 12 years, respectively. The control group included 142 post-thyroidectomy patients without hypoparathyroidism. Patients in the postsurgical hypoparathyroidism group were older and had higher calcium and PTH levels at diagnosis than the non-surgical hypoPT patients. Comparing the postsurgical hypoPT and postsurgical normocalcemic control patients revealed a significantly higher BMD in the hypoPT group. Yet, fracture rates were 31% in the postsurgical hypoparathyroidism group and 21% in the control group (P = 0.1) over a similar median follow-up period (17 and 18.4 years, respectively). In both groups the most common fracture site was the spine (50% and 70%, respectively; p = 0.33), mainly nonclinical morphometric fractures. Higher phosphorus blood level was associated with increased fracture risk. CONCLUSIONS: The relatively high BMD in patients with postsurgical hypoparathyroidism is not associated with lower fracture risk. Silent morphometric fractures are quite common in this group of patients.

RESUMO

BACKGROUND: With a demonstrated association between adiposity and parathyroid hormone (PTH) levels, we hypothesized that patients with a higher body mass index (BMI) would have lower rates of postoperative hypoparathyroidism following total thyroidectomy. METHODS: retrospective review of patients undergoing total thyroidectomy from 2015 to 2021. Demographics, BMI, surgical indications, and laboratory data including pre- and postoperative PTH values were examined. RESULTS: Of the 352 patients with complete clinicopathologic data, most were female (n = 272, 77.3%) with an average age of 42.7 (SD+/-19.4). Obese (BMI 30-39.99) was most common BMI group (n = 108, 30.8%), with 11.7% (n = 41) morbidly obese (BMI > 40). Morbidly obese patients had significantly higher postoperative PTH levels than BMI < 18.5 (46.0 vs 19.3 pg/mL, P = .004). Patient race was significantly associated with pre- and postoperative PTH (P = .03, P = .004.) On multivariable analysis, preoperative PTH, race, and BMI were independent predictors of higher postoperative PTH (P < .05 for all). DISCUSSION: Patients with higher BMI and non-white race have relative protection from postoperative hypoparathyroidism.
