Govind K, Paruk IM, Motala AA. Characteristics, management and outcomes of primary hyperparathyroidism from 2009 to 2021: a single centre report from South Africa. BMC Endocr Disord 2024; 24:53. [PMID: 38664758 PMCID: PMC11044279 DOI: 10.1186/s12902-024-01583-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/16/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND There has been a notable shift towards the diagnosis of less severe and asymptomatic primary hyperparathyroidism (PHPT) in developed countries. However, there is a paucity of recent data from sub-Saharan Africa (SSA), and also, no reported data from SSA on the utility of intra-operative parathyroid hormone (IO-PTH) monitoring. In an earlier study from Inkosi Albert Luthuli Central Hospital (IALCH), Durban, South Africa (2003-2009), majority of patients (92.9%) had symptomatic disease. The aim of this study was to evaluate the clinical profile and management outcomes of patients presenting with PHPT at IALCH. METHODS A retrospective chart review of patients with PHPT attending the Endocrinology clinic at IALCH between July 2009 and December 2021. Clinical presentation, laboratory results, radiologic findings, surgical notes and histology were recorded. RESULTS Analysis included 110 patients (87% female) with PHPT. Median age at presentation was 57 (44; 67.5) years. Symptomatic disease was present in 62.7% (n:69); 20.9% (n:23) had a history of nephrolithiasis and 7.3% (n:8) presented with previous fragility fractures. Mean serum calcium was 2.87 ± 0.34 mmol/l; median serum-PTH was 23.3 (15.59; 45.38) pmol/l, alkaline phosphatase 117.5 (89; 145.5) U/l and 25-hydroxyvitamin-D 42.9 (33.26; 62.92) nmol/l. Sestamibi scan (n:106 patients) identified an adenoma in 83.02%. Parathyroidectomy was performed on 84 patients with a cure rate of 95.2%. Reasons for conservative management (n:26) included: no current surgical indication (n:7), refusal (n:5) or deferral of surgery (n:5), loss to follow-up (n:5) and assessed as high anaesthetic risk (n:4). IO-PTH measurements performed on 28 patients indicated surgical success in 100%, based on Miami criteria. Histology confirmed adenoma in 88.1%, hyperplasia in 7.1% and carcinoma in 4.8%. Post-operative hypocalcaemia developed in 30 patients (35.7%), of whom, 14 developed hungry bone syndrome (HBS). In multivariate analysis, significant risk factors associated with HBS included male sex (OR 7.01; 95% CI 1.28, 38.39; p 0.025) and elevated pre-operative PTH (OR 1.01; 95% CI 1.00, 1.02; p 0.008). CONCLUSIONS The proportion of asymptomatic PHPT has increased at this centre over the past decade but symptomatic disease remains the dominant presentation. Parathyroidectomy is curative in the majority of patients. IO-PTH monitoring is valuable in ensuring successful surgery.

Abstract
Background Primary hyperparathyroidism (PHPT) is rarely associated with the occurrence of acute or chronic pancreatitis, requiring complex perioperative management. This study aimed to assess the prevalence and disease characteristics of pancreatitis in PHPT. Materials and Methods This study is a clinicopathological analysis of the medical records of patients who were diagnosed with PHPT with pancreatitis between 1989 and 2021 in the Endocrine Surgery department, SGPGI, Lucknow. Results Out of 548 PHPT cases, 44 (8.03%) were found to be associated with pancreatitis. The mean age was 33.57 years (15-65 years); 5 were ≤20 years, while 26 were ≤30 years of age. There were 27 males and 17 females. Twenty-one cases were of acute (11 acute, nine recurrent acute, one acute on chronic), whereas 23 were of chronic pancreatitis (six chronic calcific pancreatitis). The major clinical presentation of PHPT with pancreatitis was abdominal pain (65.91%). The mean number of attacks per patient in recurrent acute pancreatitis was two. Mean PTH levels were 68.19 pmol/L. The mean tumor size (in the largest dimension) was 2.79 ± 1.4 cm while the mean tumor weight was 4.91 g. Nephrolithiasis was associated with 25 cases. An association with multiple endocrine neoplasia type 1 syndrome was seen in one case. The final histopathological diagnosis was parathyroid carcinoma in two, hyperplasia in three, and parathyroid adenoma in 39 cases. Normocalcemia was seen in 27.2%, hypercalcemic crisis in 15.9%, and 25% of patients required semi-emergency parathyroidectomy. The outcome was favorable in all, as none had any further attacks of pancreatitis. Conclusion In our study, the prevalence of pancreatitis in PHPT cases was 8.03%. The majority of patients were young. Normocalcemia was seen in 12 patients, so even if calcium levels are normal, PHPT should be suspected in young patients with pancreatitis. Parathyroidectomy resulted in the complete resolution of symptoms of pancreatitis in all 44 patients.

Abstract
Purpose Primary hyperparathyroidism (PHPT) is the underlying etiology for 90% of patients with hypercalcemia. PHPT patients have traditionally been characterized as being symptomatic or asymptomatic. However, we submit that even "asymptomatic" patients may still have clinical features, posing the idea of coining asymptomatic disease as a misnomer. This paper presents a systematic review and meta-analysis elucidating the differences between asymptomatic and symptomatic PHPT in the literature. Methods A comprehensive literature search was conducted in PubMed, Cochrane, and Web of Science databases for articles published from 2012 to 2022. Inclusion criteria consisted of all studies comparing symptomatic and asymptomatic PHPT patients. Two reviewers independently evaluated the literature using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The level of evidence was determined using the Oxford Center for Level of Evidence-Based Medicine. Data were extracted, and a meta-analysis was performed. I2 index was employed for heterogeneity. Results There were 18 studies included, with a total of 4238 patients. The average age of patients included was 56.37, with 25.7% of the cohort being male. Several studies reported clinical features even for the "asymptomatic" group. Patients in the symptomatic group tended to have higher levels of PTH and calcium. The asymptomatic group had greater levels of vitamin D. There was observed heterogeneity between the studies. Conclusions More extreme PTH, calcium values, and low vitamin D levels were seen in patients with symptomatic disease. However, asymptomatic patients occasionally exhibited clinical features. Therefore, the terminology of "asymptomatic" disease is likely inappropriate for these patients.

Abstract
Quality of life is impaired in primary hyperparathyroidism (PHPT), regardless of the severity of the disease. Clinical studies have employed different instruments, including standardized and disease-specific questionnaires, and including patients with different phenotypes of PHPT. Neuropsychiatric symptoms and decline in cognitive status are common in PHPT. Patients may complain of these issues or they can be ascertained by questionnaires; they include depression, anxiety, impaired vitality, social and emotional functions, sleep disturbances, and altered mental function. Randomized controlled trials on the effects of surgical versus non-surgical treatments have collectively shown improvement in quality of life after parathyroidectomy, but results have been heterogeneous.

Abstract
In this narrative review, we present data gathered over four decades (1980-2020) on the epidemiology, pathophysiology and genetics of primary hyperparathyroidism (PHPT). PHPT is typically a disease of postmenopausal women, but its prevalence and incidence vary globally and depend on a number of factors, the most important being the availability to measure serum calcium and parathyroid hormone levels for screening. In the Western world, the change in presentation to asymptomatic PHPT is likely to occur, over time also, in Eastern regions. The selection of the population to be screened will, of course, affect the epidemiological data (ie, general practice as opposed to tertiary center). Parathyroid hormone has a pivotal role in regulating calcium homeostasis; small changes in extracellular Ca++ concentrations are detected by parathyroid cells, which express calcium-sensing receptors (CaSRs). Clonally dysregulated overgrowth of one or more parathyroid glands together with reduced expression of CaSRs is the most important pathophysiologic basis of PHPT. The spectrum of skeletal disease reflects different degrees of dysregulated bone remodeling. Intestinal calcium hyperabsorption together with increased bone resorption lead to increased filtered load of calcium that, in addition to other metabolic factors, predispose to the appearance of calcium-containing kidney stones. A genetic basis of PHPT can be identified in about 10% of all cases. These may occur as a part of multiple endocrine neoplasia syndromes (MEN1-MEN4), or the hyperparathyroidism jaw-tumor syndrome, or it may be caused by nonsyndromic isolated endocrinopathy, such as familial isolated PHPT and neonatal severe hyperparathyroidism. DNA testing may have value in: confirming the clinical diagnosis in a proband; eg, by distinguishing PHPT from familial hypocalciuric hypercalcemia (FHH). Mutation-specific carrier testing can be performed on a proband's relatives and identify where the proband is a mutation carrier, ruling out phenocopies that may confound the diagnosis; and potentially prevention via prenatal/preimplantation diagnosis. © 2022 The Authors.

Abstract
BACKGROUND Acute pancreatitis (AP) presenting as an initial manifestation of primary hyperparathyroidism (PHPT) is uncommon, and its timely diagnosis is crucial in preventing recurrent attacks of pancreatitis.
AIM To determine the clinical, biochemical, and radiological profile of PHPT patients presenting as AP.
METHODS This is a retrospective observational study, 51 consecutive patients admitted with the diagnosis of PHPT during January 2010 and October 2021 at a tertiary care hospital in Puducherry, India was included. The diagnosis of AP was established in the presence of at least two of the three following features: abdominal pain, levels of serum amylase or lipase greater than three times the normal, and characteristic features at abdominal imaging.
RESULTS Out of the 51 consecutive patients with PHPT, twelve (23.52%) had pancreatitis [5 (9.80%) AP, seven (13.72%) chronic pancreatitis (CP)]. PHPT with AP (PHPT-AP) was more common among males with the presentation at a younger age (35.20 ± 16.11 vs 49.23 ± 14.80 years, P = 0.05) and lower plasma intact parathyroid hormone (iPTH) levels [125 (80.55-178.65) vs 519.80 (149-1649.55, P = 0.01)] compared to PHPT without pancreatitis (PHPT-NP). The mean serum calcium levels were similar in both PHPT-AP and PHPT-NP groups [(11.66 ± 1.15 mg/dL) vs (12.46 ± 1.71 mg/dL), P = 0.32]. PHPT-AP also presented with more gastrointestinal symptoms like abdominal pain, nausea, and vomiting with lesser skeletal and renal manifestations as compared to patients with PHPT-NP.
CONCLUSION AP can be the only presenting feature of PHPT. Normal or higher serum calcium levels during AP should always draw attention towards endocrine causes like PHPT.

Abstract
Primary hyperparathyroidism is not so uncommon a disease. In high-income countries, with the introduction of routine biochemical testing in 1980s, it is diagnosed early, and the majority are seen as asymptomatic disease. However, in India, a severe symptomatic form is still seen, and many times patients are undiagnosed, thus continuing to suffer debilitating disease. Here, we report such a patient who was being treated as having bony metastases from an unknown primary source, when in fact he had osteitis fibrosa cystica due to primary hyperparathyroidism and was cured after surgery.

Focused parathyroidectomy without intraoperative parathyroid hormone measurement in primary hyperparathyroidism: Still a valid approach? Surgery 2021; 170:1383-1388. [PMID: 34144815 DOI: 10.1016/j.surg.2021.05.030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/27/2021] [Accepted: 05/17/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Concern regarding suboptimal cure rates has led to some endocrine surgery units abandoning focused parathyroidectomy for primary hyperparathyroidism in favor of open bilateral neck exploration or making intraoperative parathyroid hormone estimation mandatory in focused parathyroidectomy. This study explores whether focused parathyroidectomy for radiologically localized primary hyperparathyroidism without intraoperative parathyroid hormone is still a valid approach. METHODS Retrospective review of a tertiary referral endocrine surgery unit database. All parathyroidectomies for primary hyperparathyroidism over 6 years (2013-2019) were included. Lithium-induced hyperparathyroidism, reoperations, familial disease, and concurrent thyroid surgery were excluded. Characteristics and outcomes for focused parathyroidectomy and open bilateral neck exploration were compared by intention-to-treat and treatment delivered. Persistence and recurrence, conversions and complications were analyzed as endpoints. RESULTS A total of 2,828 parathyroidectomies were performed and 2,421 analyzed. By intention to treat there were 1,409 focused parathyroidectomies and 1,012 open bilateral neck explorations. Focused parathyroidectomy patients were younger: 63 vs 66 years (P < .01); however, gender (77%, 79% female), preoperative peak serum calcium (2.72, 2.70 mmol/L [P = .23]), and serum parathyroid hormone (11.5, 11.0 pmol/L [P = .52]) did not differ. In total, 229 (16.3%) focused parathyroidectomies were converted to open bilateral neck exploration. Multiple gland disease was confirmed in 54.5% of converted patients. Median follow-up was 41 months (3-60 months). Persistence or recurrence requiring reoperation totaled 2.2% and did not differ between focused parathyroidectomy and open bilateral neck exploration in either intention to treat or final treatment analyses. Complications occurred in 1.2% of focused parathyroidectomy and 3.2% open bilateral neck exploration (P < .01). CONCLUSIONS In experienced hands and with a ready-selective approach to conversion, focused parathyroidectomy based on concordant imaging and without intraoperative parathyroid hormone may deliver equivalent cure rates to open bilateral neck exploration with significantly fewer complications. Focused parathyroidectomy without intraoperative parathyroid hormone should therefore be maintained in the endocrine surgeon's armamentarium.

Abstract
Acute pancreatitis as an initial manifestation of primary hyperparathyroidism (PHPT) is a rare occurrence and timely diagnosis of PHPT is crucial in preventing repeat attack of pancreatitis. The study aimed at evaluating the clinico-radiological profile of patients admitted with acute pancreatitis as the index presentation of PHPT and to determine the factors associated with development of severe pancreatitis. This series included retrospective analysis of medical records of 30 patients admitted with acute pancreatitis as initial manifestation of PHPT. Additionally, we analyzed the data of another 30 patients admitted with PHPT but without any evidence of pancreatitis, to serve as control group. The mean age of the subjects was 44.9±13.9 years with male to female ratio of 1.30. The mean serum calcium level was 12.24±2.79 mg/dl and five (16.6%) patients had normocalcemia at time of presentation. Presence of nephrolithiasis was significantly associated with severe pancreatitis. One patient had refractory hypercalcemia associated with renal failure and was successfully managed with denosumab. Patients with PHPT associated with acute pancreatitis had significantly higher calcium levels and lower frequency of skeletal involvement as compared to PHPT patients without pancreatitis. PHPT masquerading as acute pancreatitis is rare and high index of suspicion is required to diagnose this condition especially in the presence of normocalcemia at presentation. Patients with PHPT associated pancreatitis had male preponderance, higher calcium levels, and lower frequency of skeletal involvement as compared to PHPT patients without pancreatitis.

Abstract
BACKGROUND There is limited experience in managing pediatric primary hyperparathyroidism (PHPT). The aim of this study was to analyze the clinical presentation and outcome of surgery in children with PHPT managed at a tertiary referral center. METHODS This retrospective study (September 1989-August 2019) consisted of 35 pediatric PHPT patients (< 18 years) who underwent parathyroidectomy. Clinico-pathologic profile and outcome were noted. RESULTS The mean age of cohort was 15.2±2.9 years and girls outnumbered boys (M:F = 1:1.9). Familial and symptomatic disease was noted in 8.5 and 94.3% cases, respectively. Skeletal manifestations (83%) were the commonest followed by renal (29%). Fifty-four percent children had skeletal fractures, and 23% were bed-ridden. Among rare manifestations, hypercalcemic crisis, recurrent pancreatitis and stigmata of rickets were observed in 2.8, 11.4 and 14.2% children, respectively. Mean calcium concentration was 12.1 ± 2.0 mg/dl and PTH 91.8 ± 66.5 pmol/L. The sensitivity of preoperative imaging in parathyroid localization was 91.4%. Minimally invasive parathyroidectomy (MIP) was performed in 40% cases. Parathyroid adenoma was observed in 91.4% patients, whereas remaining had hyperplasia. Thirty-four percent suffered from Hungry bone syndrome in postoperative period. The cure rate following primary surgery was 97%. One child with persistent PHPT had successful re-operation. Median follow-up was 5 (1-17) years, and no recurrence or familial disease was revealed during this period. CONCLUSION Majority of pediatric patients present with symptomatic PHPT. Despite relatively high incidence of familial disease select pediatric patients can undergo successful MIP.

Abstract
While the developed world is focusing on laying guidelines for selecting out cases of Asymptomatic primary hyperparathyroidism (PHPT) for surgical intervention and promoting minimal access surgery, the developing world is observing a change in disease spectrum from advanced symptomatic to lesser degree of symptomatic disease and not many with associated Vitamin D deficiency. Few studies from the developing countries of the world have focused on the changing clinical spectrum of PHPT. Objective of this study is to review the changing profile of PHPT in developing world. A systematic literature search was done in December 2017 focussing on publications from the developing world. All studies pertaining to the epidemiology of PHPT published after 1st January 2000 and published in English language were included for analysis. Most of the studies published from developing countries report a predominance of symptomatic disease (79.6% of all included patients) with musculoskeletal disease present in the majority of patients (52.9%). The combined mean serum total calcium (11.9 ± 1.4 mg/dL), serum PTH (668.6 ± 539 pg/mL), serum alkaline phoshpatase (619 ± 826.9 IU/L) and weight of excised parathyroid glands (4.4 ± 3.8 grams) are much higher than those reported from the western studies. Despite this, we found that there is a distinct trend towards a milder form of disease presentation and biochemical profile noticeable in more recent times. Although there is a striking difference in all aspects of PHPT disease epidemiology, clinical presentation and biochemical profile of developing and developed countries, there is a distinct trend towards a milder form of disease presentation and biochemical profile in more recent times.

Abstract
BACKGROUND Despite the benefits of focused parathyroidectomy (FPTx), few studies have questioned its durability with lower long-term cure rates than bilateral or conventional parathyroidectomy (CPTx). The objective of this study is to bring out the information on the type of surgical management versus cure rate, recurrence, and role of intra-operative parathyroid hormone (IOPTH) level monitoring of PHPT patients. MATERIAL AND METHODS This was a retrospective study of all PHPT patients treated at our center based on operative approach (CPTx vs FPTx) or use of IOPTH. Treatment failure was divided into persistent or recurrent disease, based on documentation of hypercalcemia in combination with an inappropriate PTH within 6 months or more of surgery, respectively. RESULTS Overall, 50.78% patients underwent CPTx and 49.32% FPTx. 29 FPTx were converted to CPTx. Intention to treat analysis between CPTx and FPTx showed that the persistence rate was not statistically different at 2.54% and 4%, respectively (P = 0.98). Furthermore, when the persistence rate was scrutinized by a treatment received (TR) instead of ITT analysis, the persistence rate was higher for the patients who underwent TR-CPTX than for the patients subjected to TR-FPTX (3.22% vs 1.08%) but not significant statistically. We further analyzed the outcome of FPTx with IOPTH (n = 213) and FPTx without IOPTH (n = 28). The outcome did not differ between two groups statistically. CONCLUSION FPTx yields a similar success rate as compared to CPTx even in symptomatic PHPT patients and can be performed safely even without intra-opeartive adjunct IOPTH in selected patients.

Abstract
Primary hyperparathyroidism (pHPT) is the third most common endocrine disease and is characterized by hypercalcaemia and elevated or inappropriately 'normal' levels of the parathyroid hormone (PTH). The main target organs of PTH are the skeletal system and the kidneys. Before the 1970s, pHPT was a rarely detected disease associated with notable morbidity and premature mortality. Introduction of biochemical screening, allowing for a wide range of indications, has contributed to the detection of the full spectrum of the disease. A new entity with an isolated elevation of PTH, normocalcaemic HP, has emerged and is currently being explored. The highest incidence of pHPT, 3-5%, is observed amongst women, and the prevalence increases with age. The female-to-male ratio is 3-4 : 1 except in younger patients where distribution is equal and known hereditary causes account for approximately 10% of the cases. In the last few decades, it has become evident that fewer patients than previously believed are truly asymptomatic. The cause of pHPT is often a benign tumour, a parathyroid adenoma, and the only definite treatment is parathyroidectomy (PTX). No medical treatment, single or combined, can achieve a curing of pHPT. Recent data indicate that PTX, despite being proven to be cost-effective compared to conservative treatment, is underutilized, especially in elderly pHPT patients. The decision of PTX should always be based on a safe diagnosis, and the potential benefits of curative treatment should not be outweighed by the risks of surgery or anaesthesia.

Abstract
BACKGROUND Primary hyperparathyroidism (PHPT), the most common cause of hypercalcemia, is most often identified in postmenopausal women. The clinical presentation of PHPT has evolved over the past 40 years to include three distinct clinical phenotypes, each of which has been studied in detail and has led to evolving concepts about target organ involvement, natural history, and management. METHODS In the present review, I provide an evidence-based summary of this disorder as it has been studied worldwide, citing key concepts and data that have helped to shape our concepts about this disease. RESULTS PHPT is now recognized to include three clinical phenotypes: overt target organ involvement, mild asymptomatic hypercalcemia, and high PTH levels with persistently normal albumin-corrected and ionized serum calcium values. The factors that determine which of these clinical presentations is more likely to predominate in a given country include the extent to which biochemical screening is used, vitamin D deficiency is present, and whether parathyroid hormone levels are routinely measured in the evaluation of low bone density or frank osteoporosis. Guidelines for parathyroidectomy apply to all three clinical forms of the disease. If surgical guidelines are not met, parathyroidectomy can also be an appropriate option if no medical contraindications are present. If either the serum calcium or bone mineral density is of concern and surgery is not an option, pharmacological approaches are available and effective. CONCLUSIONS Advances in our knowledge of PHPT have guided new concepts in diagnosis and management.

Abstract
OBJECTIVE The clinical presentation of primary hyperparathyroidism (PHPT) has changed widely in developed countries in the last few decades. We evaluated its variations in our series over a 20-year period (i.e., 1997-2016). METHODS A retrospective survey was conducted in our series of 364 well-characterized consecutive patients, arbitrarily divided into 4 consecutive 5-year periods at diagnosis. RESULTS In the overall series, only estimated glomerular function (eGFR) and urinary calcium (UCa) showed a significant upward trend ( P = .032 and .039, respectively), whereas demographic and clinical characteristics were stable. The UCa upward trend was also confirmed for the subgroup of symptomatic patients ( P = .013). No difference was observed in the demographic, clinical, or biochemical characteristics of asymptomatic patients or in the fraction of patients meeting surgical criteria. CONCLUSION The clinical presentation of PHPT was stable over 20 years in our large series. ABBREVIATIONS Ca = calcium; eGFR = estimated glomerular filtration rate; 25OHD = 25-hydroxyvitamin D; PHPT = primary hyperparathyroidism; PTH = parathyroid hormone; UCa = urinary calcium.
