Abstract
BACKGROUND Improvements in quality of life (QoL) after parathyroidectomy in patients with primary hyperparathyroidism (PHPT) is discussed. It has not been analyzed whether these improvements can be influenced by a specific socio-personal or clinical patient profile. OBJECTIVES to analyze QoL differences after parathyroidectomy and to determine a socio-personal and clinical profile that influences improvement after parathyroidectomy. METHODS A longitudinal prospective cohort study in patients with PHPT. SF-36 and PHPQOL questionnaires were completed by the patients. A comparative preoperatory analysis was carried out, at three and twelve months after surgery. Student's t test was used for the correlations. The size of the effect was assessed using G*Power software. A multivariate analysis was performed to evaluate the socio-personal and clinical variables affecting the improvement in QoL after surgery. RESULTS Forty-eight patients were analyzed. Three months after surgery an improvement was found in physical function, general health, vitality, social function, emotional role, mental health and in the patient's declared health assessment. One year after the intervention a general improvement was observed, with a greater effect on mental health and declared health evolution. Patients with bone pain presented with a higher probability of improvement after surgery. Patients with prior psychological disease had a lower associated probability of an improvement and high levels of PTH related to a greater probability of improvement after surgery. CONCLUSIONS There is an improvement in the QoL of PHPT patients after parathyroidectomy. Patients with bone pain and high PTH levels prior to the parathyroidectomy present with a greater probability of having a greater improvement in QoL after surgery.

Influence of Parathyroidectomy on Sleep Quality in Primary Hyperparathyroidism. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2021.

Abstract
We investigated the impact of parathyroidectomy on sleep quality in patients with primary hyperparathyroidism (pHPT). Thirty consecutive patients with pHPT were enrolled in the study within 1 year. pHPT was diagnosed by typical symptoms accompanied by an elevated level of parathormone. The Pittsburgh Sleep Quality Index (PSQI) was used for the evaluation of sleep 1 day before and 6 months after parathyroidectomy. The mean total PSQI score was elevated to 6.8 ± 0.6 points before surgery, which was in the pathological cut-off of greater than ≥5, indicating impaired sleep quality. After parathyroidectomy, the total score declined insignificantly, amounting to 5.6 ± 0.4 (p > 0.05). Nevertheless, the number of patients with a score of ≥5 before surgery decreased from 21 (70%) to 16 (53%) after surgery. There also was a significant improvement in sleep latency (p = 0.05) and sleep efficiency (p = 0.02) domains of PSQI. We conclude that 70% of patients with untreated pHPT suffered from sleep disorders that improved after parathyroidectomy. The clinical consequence is that patients with pHPT should be questioned about having sleep disorders, which might influence the decision-making concerning parathyroidectomy. With the relation reversed, patients without pHPT but suffering from sleep disturbance should be tested for pHPT.

Abstract
Dementia is a highly prevalent chronic disease among the older population, affecting more than 50 million people worldwide and representing a huge healthcare, social and economic burden. Dementia, and in particular Alzheimer's disease, prevalence is expected to raise within the next few years. Unfortunately, no disease-modifying therapies are available so far, despite a plethora of clinical trials targeting the hallmarks of Alzheimer's disease. Given these premises, it appears crucial to address not only the neuropathological correlates of the disease, but also the modifiable risk factors. Among them, evidence suggest a role of the endocrine system not only in the brain development, but also in the maintenance of its health, having neurotrophic, antioxidant and metabolic functions crucial for the cognitive abilities. This review focuses on the evidence evaluating the impact of the endocrine systems, in particular thyroid function, insulin resistance, parathyroid hormone, vitamin D and sexual hormones on cognitive status. Results from epidemiological, preclinical and some clinical studies demonstrated the link between thyroid, parathyroid hormone and vitamin D and cognitive status, between diabetes, and insulin resistance in particular, and dementia, between sexual and adrenal hormones, particularly estrogen variation at menopause, and cognitive decline. The growing interest on the modifiable risks factors of cognitive decline increased the knowledge about the complex interplay of endocrine systems and cognition, highlighting the need and the usefulness of a multidisciplinary approach to the prevention of a complex and devastating disease.

Cognition and cerebrovascular function in primary hyperparathyroidism before and after parathyroidectomy. J Endocrinol Invest 2020; 43:369-379. [PMID: 31621051 PMCID: PMC7275118 DOI: 10.1007/s40618-019-01128-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Accepted: 10/09/2019] [Indexed: 12/11/2022]
Abstract
PURPOSE There are cognitive changes in primary hyperparathyroidism (PHPT) that improve with parathyroidectomy, but the mechanism of cognitive dysfunction has not been delineated. We assessed if cerebrovascular function is impaired in PHPT, improves post-parathyroidectomy and is associated with PTH level and cognitive dysfunction. METHODS This is an observational study of 43 patients with mild hypercalcemic or normocalcemic PHPT or goiter. At baseline, cerebrovascular function (dynamic cerebral autoregulation and vasomotor reactivity) by transcranial Doppler and neuropsychological function were compared between all three groups. A subset underwent parathyroidectomy or thyroidectomy, and was compared 6 months post-operatively. RESULTS Mean cerebrovascular and neuropsychological function was normal and no worse in PHPT compared to controls preoperatively. Higher PTH was associated with worse intracerebral autoregulation (r = - 0.43, p = 0.02) and worse cognitive performance on some tests. Post-parathyroidectomy, mood improved significantly, but changes did not differ compared to those having thyroidectomy (p = 0.84). There was no consistent improvement in cognition or change in vascular function in either surgical group. CONCLUSIONS Although higher PTH was associated with worse intracerebral autoregulation, cerebrovascular function, cognition and mood were normal in mild PHPT. PTX did not improve vascular or cognitive function. The observed improvement in mood cannot be clearly attributed to PTX. Notwithstanding the small sample size, the results do not support changing current criteria for parathyroidectomy to include cognitive complaints. However, the associations between PTH, cognition and cerebral autoregulation merit future studies in those with more severe hyperparathyroidism.

Abstract
Cognitive impairment is very common in chronic kidney disease (CKD) and is strongly associated with increased mortality. This review article will discuss the pathophysiology of cognitive impairment in CKD, as well as the effect of dialysis and transplantation on cognitive function. In CKD, uremic toxins, hyperparathyroidism and Klotho deficiency lead to chronic inflammation, endothelial dysfunction and vascular calcifications. This results in an increased burden of cerebrovascular disease in CKD patients, who consistently have more white matter hyperintensities, microbleeds, microinfarctions and cerebral atrophy on magnetic resonance imaging scans. Hemodialysis, although beneficial in terms of uremic toxin clearance, also contributes to cognitive decline by causing rapid fluid and osmotic shifts. Decreasing the dialysate temperature and increasing total dialysis time limits these shifts and helps maintain cognitive function in hemodialysis patients. For many patients, kidney transplantation is the preferred treatment modality, because it reverses the underlying mechanisms causing cognitive impairment in CKD. These positive effects have to be balanced against the possible neurotoxicity of infections and immunosuppressive medications, especially glucocorticosteroids and calcineurin inhibitors. A limited number of studies have addressed the overall effect of transplantation on cognitive function. These have mostly found an improvement after transplantation, but have a limited applicability to daily practice because they have only included relatively young patients.

Abstract
The clinical picture of primary hyperparathyroidism (PHPT) has changed over the last three decades and many asymptomatic patients are now diagnosed through the unexpected finding of high serum calcium levels. However, though not yet considered as typical features of the disease and therefore not included in the guidelines for surgery, many data are available on neuropsycological manifestations and their impact on quality of life in asymptomatic patients. PHPT patients indeed show early experience nonspecific symptoms, such as weakness, depression, sleep disturbance, memory loss and anxiety. Although the underlining mechanisms have not been still identified, the prevalence of psychiatric and cognitive deficits has been investigated in many studies, as well as the possible association with quality of life and well-being improvement after surgery. This article aims to review the current knowledge on quality of life in PHPT patients before and after surgery and the possible clinical implications of these findings.

Abstract
OBJECTIVE To ascertain the preoperative anxiety level and different factors responsible in patients admitted for an elective surgical procedure in a tertiary care public hospital. METHODS Anxiety levels were measured in admitted patients of the Civil Hospital, Karachi, Pakistan awaiting elective surgery from October to January 2006. In the afternoon preceding surgery, patients were asked to complete 2 visual analogue scales (VAS) regarding anxiety about the proposed surgery and anesthesia (range, 0 = `not anxious at all` to 100 = `extremely anxious`). They were then asked to select different factors responsible for their anxiety from a list. RESULTS Mean anxiety score for surgery was 57.65+/-25.1 and for anesthesia was 38.14+/-26.05. There was a statistically significant high level of pre-operative anxiety in females as compared to males (p<0.01). The most common factors contributing to anxiety were concern about family in 173 (89.6%) patients, fear of complications in 168 (87%), results of operation in 159 (82.4%), and postoperative pain in 152 (78.8%). Fifty-six percent of patients thought that their anxiety would be lessened by a detailed explanation regarding the operation and anesthesia. CONCLUSION Our patients experience very high levels of preoperative anxiety. This can be easily measured in the preoperative period and allows detection of patients with high anxiety, encouraging appropriate steps to ameliorate this. Establishment of preoperative counseling clinics and properly informed consent taken before surgery will help in reducing preoperative anxiety.

Abstract
OBJECTIVE Primary hyperparathyroidism (PHPT) is associated with feelings of fatigue and depression, as well as limitation to physical and mental functioning. These quality of life (QoL) characteristics improve after parathyroidectomy. However, whether former patients fully regain QoL compared with healthy controls is largely unknown. DESIGN AND PATIENTS Cross-sectional study. Fifty-one former PHPT patients, successfully treated by surgery (mean time since parathyroidectomy 7.4 (range 5-15) years), and 51 sex- and age-matched healthy controls. METHODS The 36-item Short-Form Health Survey version 2 and the WHO-Five Well-being Index. The surveys included questions on overall physical and mental health, functioning, and limitation in daily life activities. RESULTS Former patients scored significantly lower compared with controls in physical functioning (P=0.01), role limitation caused by emotional problems (P=0.01), vitality (P<0.001), and general health (P=0.01). Compared with the controls, cases had a lower median (interquartile range) score of physical component summary (PCS; 54.9 (47.9-58.7) vs 49.6 (45.2-55.9), P=0.03) and mental component summary (MCS; 55.4 (49.7-58.1) vs 52.5 (44.7-55.5), P=0.04). There was no association between time since operation and PCS or MCS. Compared with controls, cases had higher body mass index (BMI; 26.0±4.7 vs 28.8±6.0 kg/m(2), P<0.001) and a higher frequency of cardiovascular diseases (CVD; 41.2 vs 62.7%, P=0.03). After adjustment for differences in BMI and CVD, PCS did no longer differ between groups. However, adjustments did not change the finding of a lower MCS in cases compared with controls. CONCLUSION Even though QoL may improve substantially after surgery, former PHPT patients still have reduced QoL compared with healthy controls.

Abstract
OBJECTIVE This study had 2 aims: (1) to assess the timing and magnitude of psychological and neurocognitive changes before and after parathyroidectomy and (2) to examine correlations between changes in serum biomarkers and psychological symptoms and neurocognitive performance. BACKGROUND Psychological and neurocognitive changes are common in patients with primary hyperparathyroidism (pHPT), but the associations of serum biomarkers and these changes have not been established. METHODS This prospective cohort study carried out at a large tertiary care referral center from 2004 to 2008 screened all adult patients with the biochemical diagnosis of pHPT who underwent first-time parathyroidectomy. Laboratory results, psychological symptom reports, and results of neurocognitive testing using validated instruments were obtained preoperatively and at 1, 3, and 6 months postoperatively. Outcomes measures included serum calcium, intact parathyroid hormone (iPTH), and thyroid stimulating hormone; psychological symptom inventories (Beck Depression Inventory-II, Brief Symptom Inventory-18, and Spielberger State-Trait Anxiety Inventory); and neurocognitive test scores (Rey Auditory Verbal Learning Test and Groton Maze Learning Test). RESULTS Two hundred twelve patients were enrolled; mean age was 60 years; 78% were female and had low comorbidity; 78% had parathyroidectomy under ambulatory, minimally invasive techniques; cure rate was 99%. Improvements in psychological and neurocognitive measures were observed at all postoperative follow-up visits. The most pronounced improvements were noted in depressive and anxiety symptoms, and visuospatial and verbal memory. Examination of change scores revealed that postoperative reduction in iPTH was associated with a decrease in state anxiety, which was also associated with improvement in visuospatial working memory. CONCLUSIONS Reduction in mood and anxiety symptoms is associated with reductions in both iPTH and spatial working memory in patients with pHPT who undergo successful parathyroidectomy.

Abstract
Cognitive and affective complaints are common in patients with primary hyperparathyroidism (PHPT), but few studies have used psychometric testing to document these symptoms and their response to parathyroidectomy. The current study sought to clarify the nature of cognitive and affective impairments in PHPT and changes postparathyroidectomy. One hundred eleven patients with PHPT underwent neuropsychological evaluation prior to parathyroidectomy with 68 returning for an early postsurgical evaluation. Changes in cognition were assessed using practice effect corrected reliable change indices. Biochemical and anesthesia variables were compared between groups who improved and declined. In a subset of patients, assessment revealed a significant pattern of cognitive slowing, reductions in psychomotor speed, memory impairment, and depression prior to parathyroidectomy. Postsurgical evaluations revealed a trend for improvements on timed tests and depression but a decline in memory. Older patients responded less well to surgical intervention, as did patients who experienced more dramatic changes in biochemical status following surgery. Cognitive changes early postparathyroidectomy are characterized by improved information processing speed and decline in verbal memory, with younger patients more likely to recover during this acute phase. The need for longer-term follow-up studies and increasing utilization of neuropsychological assessments in this population are discussed.

Abstract
BACKGROUND At the Third International Workshop on Asymptomatic Primary Hyperparathyroidism (PHPT) in May 2008, recent data on the disease were reviewed. We present the results of a literature review on issues arising from the clinical presentation and natural history of PHPT. METHODS Questions were developed by the International Task Force on PHPT. A comprehensive literature search for relevant studies was reviewed, and the questions of the International Task Force were addressed by the Consensus Panel. CONCLUSIONS 1) Data on the extent and nature of cardiovascular involvement in those with mild disease are too limited to provide a complete picture. 2) Patients with mild PHPT have neuropsychological complaints. Although some symptoms may improve with surgery, available data remain inconsistent on their precise nature and reversibility. 3) Surgery leads to long-term gains in spine, hip, and radius bone mineral density (BMD). Because some patients have early disease progression and others lose BMD after 8-10 yr, regular monitoring (serum calcium and three-site BMD) is essential in those followed without surgery. Patients may present with normocalcemic PHPT (normal serum calcium with elevated PTH concentrations; no secondary cause for hyperparathyroidism). Data on the incidence and natural history of this phenotype are limited. 4) In the absence of kidney stones, data do not support the use of marked hypercalciuria (>10 mmol/d or 400 mg/d) as an indication for surgery for patients. 5) Patients with bone density T-score -2.5 or less at the lumbar spine, hip, or distal one third radius should have surgery.

Abstract
The case of a 76-year-old female patient is presented with a two-year history of progressive dementia, apathy and gait impairment. Initially, Alzheimer's disease was diagnosed and she was given donepezil for one year with no significant improvement. An extensive blood and biochemical control revealed high serum calcium and parathormone levels, and normal thyroid hormones and anti-thyroid antibodies. Ultrasound of thyroid and parathyroid glands revealed an adenoma of the right parathyroid. The detailed investigation for causes of secondary hyperparathyroidism was negative. Due to the absence of clinical hyperparathyroidism she was initially treated conservatively. At referral, the neurological picture consisted of: mild signs of parkinsonism, moderate dementia (MMSE=15) and severe behavioural disturbances. Because of the continuous aggravation of the cognitive deficit, parathyroidectomy was decided although there were no clinical or laboratory signs of involvement from other organs. Three weeks after the operation the neurological picture showed dramatical improvement. Parkinsonism and behavioural disorders were remarkably reduced and the MMSE score raised to 25. In summary we report an exceptional case of primary hyperparathyroidism (PHPT) presenting as dementia and treated successfully by parathyroidectomy.

Abstract
Neuropsychological symptoms are found in a certain number of patients with primary hyperparathyroidism (PHPT). Preoperative and postoperative quality of life, anxiety, and depression are measured to analyze the impact of parathyroidectomy on these symptoms. In this prospective study, 66 patients underwent parathyroidectomy for PHPT and were evaluated pre- and postoperatively with two validated psychometric instruments (HADS, PHQ-9). Health-related quality of life was measured with a 12-item short-form health survey (SF-12). Preoperatively, the median physical component score (SF-12) of 43.0 and mental component score of 43.5 were lower than those of the general population (52.8 and 54.2 points, respectively). One year postoperatively the mental component score increased to 48.6 (p = 0.011), whereas the physical functioning scale scored 45.3 and therefore did not change significantly (p = 0.585). Preoperatively, symptoms of depression were found in 23.4% of the patients, and 15.6% of the patients displayed symptoms of anxiety (HADS). The prevalence of depression was significantly higher in patients with preoperative serum calcium levels > 11.2 mg/dl (2.8 mmol/L) (p = 0.015). Twelve months postoperatively, the overall proportion of patients with anxiety and depression decreased to 7.8% and 15.7%, respectively (p = NS). The severity of depression as measured with the PHQ-9 declined postoperatively as well. In this study, preoperative neuropsychological symptoms were related to the serum calcium levels. Postoperative health-related quality of life improved significantly. Among patients with preoperative symptoms of depression and anxiety, both symptoms were alleviated significantly at the 12-month follow-up. Therefore, surgery for PHPT seems to be effective in reducing neuropsychological morbidity associated with PHPT.

Abstract
PURPOSE OF REVIEW Clinical guidelines for the treatment of primary hyperparathyroidism have been established by the 2002 NIH workshop on asymptomatic primary hyperparathyroidism. The panel called for further study of the ill-defined psychiatric and cognitive changes often seen in patients with primary hyperparathyroidism. The present paper provides a rigorous, updated review of the most recent advances and studies that have measured health-related quality of life, neurocognitive and psychiatric changes, as well as neurophysiologic imaging in patients with primary hyperparathyroidism undergoing parathyroidectomy. RECENT FINDINGS In studies conducted pre and postparathyroidectomy, six recent articles have described improvements in health-related quality of life. Five studies included evaluations with validated psychiatric and cognitive tests in prospective case-control trials, and showed varied improvements in depression, memory and concentration after parathyroidectomy. Two studies evaluated in a preliminary fashion the brains of patients with primary hyperparathyroidism with functional imaging studies, showing regional cerebral blood flow changes and prefrontal cortical activation with sleep improvement in postsurgical patients. SUMMARY The studies described in this paper underline the benefits of surgical treatment on nontraditional symptoms in patients with primary hyperparathyroidism, and open the door to the continued study of the endocrine effects of primary hyperparathyroidism on brain function.

Abstract
Since the advent of multichannel autoanalyzers and routine screening of serum calcium levels, prevalence of primary hyperparathyroidism (pHPT) has increased to between 0.1% and 0.4%. As more patients present with "asymptomatic" pHPT, ideal treatment of "mild" disease becomes more controversial, with the possibility of safe, nonoperative management in a selected group of patients. Accumulated evidence confirms that the majority of these patients suffer from vague, nonspecific complaints that are very real and can improve following parathyroidectomy. Furthermore, parathyroidectomy in patients with pHPT has been demonstrated to improve bone mineral density, reduce fracture risk, and improve health-related quality of life and possibly overall survival. Therefore, all patients with primary hyperparathyroidism should be referred for surgical evaluation by an experienced endocrine surgeon.
