ABSTRACT
@#Primary hyperparathyroidism commonly affects elderly women. When present in the young population, it is usually asymptomatic, most frequently due to a parathyroid adenoma and the definitive management is surgical excision. Uncommonly, 5-10% of patients fail to achieve long-term cure after initial parathyroidectomy and 6-16% of them is due to an ectopic parathyroid adenoma that will require focused diagnostic and surgical approaches. We report a 21-year-old male who had bilateral thigh pain. Work-up revealed bilateral femoral fractures, brown tumors on the arms and multiple lytic lesions on the skull. Serum studies showed hypercalcemia (1.83 mmol/L), elevated parathyroid hormone [(PTH) 2025.10 pg/mL], elevated alkaline phosphatase (830 U/L), normal phosphorus (0.92 mmol/L) and low vitamin D levels (18.50 ng/mL). Bone densitometry showed osteoporotic findings. Sestamibi scan showed uptake on the left superior mediastinal region consistent with an ectopic parathyroid adenoma. Vitamin D supplementation was started pre-operatively. Patient underwent parathyroidectomy with neck exploration; however, the pathologic adenoma was not visualized and PTH levels remained elevated post-operatively. Chest computed tomography with intravenous contrast was performed revealing a mediastinal location of the adenoma. A repeat parathyroidectomy was done, with successful identification of the adenoma resulting in a significant drop in PTH and calcium levels. Patient experienced hungry bone syndrome post-operatively and was managed with calcium and magnesium supplementation. A high index of suspicion for an ectopic adenoma is warranted for patients presenting with hypercalcemia and secondary osteoporosis if there is persistent PTH elevation after initial surgical intervention. Adequate follow-up and monitoring is also needed starting immediately in the post-operative period to manage possible complications such as hungry bone syndrome.

As neoplasias endócrinas múltiplas (NEM) são síndromes genéticas autossômicas dominantes implicadas no desenvolvimento de neoplasias benignas ou malignas, envolvendo ao menos duas glândulas endócrinas. Entre seus subtipos, está a NEM2A, que consiste em carcinoma medular de tireoide (CMT), feocromocitoma e hiperparatireoidismo. Este texto apresente o relato de caso de um paciente de 40 anos, previamente hígido, que passou a apresentar episoÌdios de cefaleia associada a sudorese profusa, voÌmitos e taquicardia. Evoluiu com distensaÌo abdominal intensa após alimentaçaÌo por via oral, perda ponderal, desnutrição, astenia, obstipação, humor deprimido e picos pressóricos. Exames laboratoriais evidenciaram alterações dos hormônios tireoidianos, PTH e hormônios da adrenal. Foi levantada a suspeita clínica de NEM2A, posteriormente corroborada pelos diagnósticos anatomopatológicos de feocromocitoma e CMT, associados à presença de hiperparatireoidismo. Foi possível concluir que, a despeito de sua baixa prevalência na população geral, a NEM é uma síndrome clínica de grande relevância, tendo em vista os impactos para os pacientes e famílias acometidas. Dessa forma, é necessário que os profissionais de saúde tenham conhecimento acerca da síndrome e que o Sistema Único de Saúde (SUS) esteja apto a assistir aos pacientes portadores de NEM, possibilitando diagnóstico precoce e tratamento adequado.
Multiple endocrine neoplasias (MEN) are dominant autosomal genetic syndromes involved in the development of benign or malignant tumors in at least two endocrine glands. MEN2A is one of its subtypes, which consists of medullary thyroid carcinoma (MTC), pheochromocytoma, and hyperparathyroidism. This study reports the case of a healthy 40-year-old male patient presenting with episodes of headache associated with profuse sweating, vomiting, and tachycardia. The patient evolved with severe abdominal distension after oral feeding, weight loss, malnutrition, asthenia, constipation, depressed mood, and pressure peaks. Laboratory tests showed abnormalities in thyroid, parathyroid (PTH), and adrenal hormones thus raising the hypothesis of MEN2A, which was later corroborated by the histological diagnosis of pheochromocytoma and MTC, associated with hyperparathyroidism. The results indicate that, despite its low prevalence in the general population, MEN has a great impact on affected patients and families, thus being a relevant clinical syndrome. For enabling early diagnosis and adequate treatment, health professionals must be familiarized with such a condition, and the Brazilian Unified Health System (SUS) must be able to assist affected patients.
Las neoplasias endocrinas múltiples (NEM) son síndromes genéticos autosómicos dominantes involucrados en el desarrollo de neoplasias benignas o malignas, que afectan al menos dos glándulas endocrinas. Entre sus subtipos se encuentra NEM2A, que consiste en carcinoma medular de tiroides (CMT), feocromocitoma e hiperparatiroidismo. Este es un reporte de caso de un paciente de 40 años de edad, previamente sano, que comenzó a presentar episodios de cefalea asociada a sudoración profusa, vómitos y taquicardia. Evolucionó con distensión abdominal severa después de alimentarse, pérdida de peso, desnutrición, astenia, estreñimiento, estado de ánimo deprimido y picos de presión. Las pruebas de laboratorio mostraron alteraciones en las hormonas tiroideas, PTH y hormonas suprarrenales. Se planteó la hipótesis de MEN2A, posteriormente corroborada por el diagnóstico anatomopatológico de feocromocitoma y CMT, asociado a hiperparatiroidismo. Se pudo concluir que, a pesar de su baja prevalencia en la población general, el NEM es un síndrome clínico de gran relevancia, dado el impacto que tiene en los pacientes y familiares afectados. Por tanto, es necesario que los profesionales sanitarios tengan conocimiento sobre el síndrome y que el Sistema Único de Salud (SUS) sea capaz de asistir a los pacientes con NEM, posibilitándoles diagnóstico precoz y tratamiento adecuado.

@#Giant parathyroid adenoma (GPA) is defined as adenoma larger than 3.5 g. Twenty-one cases of parathyroid mass >3.5 g in patients with primary hyperparathyroidism who underwent parathyroidectomy in Hospital Putrajaya, Malaysia were identified. Most cases presented with nephrolithiasis. Two cases are reported as parathyroid cancer. GPA has significantly higher serum calcium and iPTH levels and can be asymptomatic. Parathyroid carcinoma patients are frequently symptomatic, with large tumors. Differentiating GPA from parathyroid cancer is important as it determines the subsequent surgical intervention.

Hypercalcemia is common in patients after kidney transplantation (KTx) and is associated with persistent hyperparathyroidism in the majority of cases. This retrospective, single-center study evaluated the prevalence of hypercalcemia after KTx. KTx recipients were evaluated for 7 years after receiving kidneys from living or deceased donors. A total of 301 patients were evaluated; 67 patients had hypercalcemia at some point during the follow-up period. The median follow-up time for all 67 patients was 62 months (44; 80). Overall, 45 cases of hypercalcemia were classified as related to persistent post-transplant hyperparathyroidism (group A), 16 were classified as "transient post-transplant hypercalcemia" (group B), and 3 had causes secondary to other diseases (1 related to tuberculosis, 1 related to histoplasmosis, and 1 related to lymphoma). The other 3 patients had hypercalcemia of unknown etiology, which is still under investigation. In group A, the onset of hypercalcemia after KTx was not significantly different from that of the other groups, but the median duration of hypercalcemia in group A was 25 months (12.5; 53), longer than in group B, where the median duration of hypercalcemia was only 12 months (10; 15) (P<0.002). The median parathyroid hormone blood levels around 12 months after KTx were 210 pg/mL (141; 352) in group A and 72.5 pg/mL (54; 95) in group B (P<0.0001). Hypercalcemia post-KTx is not infrequent and its prevalence in this center was 22.2%. Persistent hyperparathyroidism was the most frequent cause, but other important etiologies must not be forgotten, especially granulomatous diseases and malignancies.

ABSTRACT Background: Persistent hyperparathyroidism post-transplant is associated with increases in the incidence of cardiovascular events, fractures, and deaths. The aim of this study was to compare both therapeutic options available: parathyroidectomy (PTX) and the calcimimetic agent cinacalcet. Methods: A single center retrospective study including adult renal transplant recipients who developed hypercalcemia due to persistent hyperparathyroidism. Inclusion criteria: PTH > 65 pg/mL with serum calcium > 11.5 mg/dL at any time after transplant or serum calcium persistently higher than 10.2 mg/dL one year after transplant. Patients treated with cinacalcet (n=46) were compared to patients treated with parathyroidectomy (n=30). Follow-up period was one year. Clinical and laboratory data were analyzed to compare efficacy and safety of both therapeutic modalities. Results: PTX controlled calcemia faster (month 1 x month 6) and reached significantly lower levels at month 12 (9.1±1.2 vs 9.7±0.8 mg/dL, p < 0.05); PTX patients showed significantly higher levels of serum phosphate (3.8±1.0 vs 2.9±0.5 mg/dL, p < 0.05) and returned PTH to normal levels (45±51 pg/mL). Cinacalcet, despite controlling calcium and phosphate in the long term, decreased but did not correct PTH (197±97 pg/mL). The proportion of patients that remained with PTH above normal range was 95% in the cinacalcet group and 22% in the PTX group. Patients treated with cinacalcet had better renal function (creatinine 1.2±0.3 vs 1.7±0.7 mg/dL, p < 0.05). Conclusions: Surgical treatment was superior to cinacalcet to correct the metabolic disorders of hyperparathyroidism despite being associated with worse renal function in the long term. Cinacalcet proved to be a safe and well tolerated drug.
RESUMO Introdução: O hiperparatireoidismo persistente pós-transplante está associado a aumento na incidência de eventos cardiovasculares, fraturas e óbitos. O objetivo deste estudo foi comparar as opções terapêuticas disponíveis: paratireoidectomia (PTX) e o agente calcimimético cinacalcete. Métodos: Estudo retrospectivo de um único centro incluiu pacientes transplantados renais adultos que desenvolveram hipercalcemia devido a hiperparatireoidismo persistente. Critérios de inclusão: PTH > 65 pg/mL com cálcio sérico > 11,5 mg/dL a qualquer momento após o transplante, ou cálcio sérico persistentemente superior a 10,2 mg/dL um ano após o transplante. Os pacientes tratados com cinacalcete (n = 46) foram comparados aos pacientes tratados com paratireoidectomia (n = 30). O período de acompanhamento foi de um ano. Dados clínicos e laboratoriais foram analisados para comparar a eficácia e a segurança de ambas as modalidades terapêuticas. Resultados: a PTX controlou a calcemia mais rapidamente (mês 1 x mês 6) e atingiu níveis significativamente mais baixos no mês 12 (9,1 ± 1,2 v.s. 9,7 ± 0,8 mg/dL, p < 0,05); pacientes submetidos à PTX apresentaram níveis significativamente mais altos de fósforo sérico (3,8 ± 1,0 v.s. 2,9 ± 0,5 mg/dL, p < 0,05) e retornaram aos níveis normais de PTH (45 ± 51 pg/mL). O cinacalcete, apesar de controlar o cálcio e o fósforo no longo prazo, diminuiu, mas não corrigiu o PTH (197 ± 97 pg/mL). A proporção de pacientes que permaneceram com PTH acima da faixa normal foi de 95% no grupo cinacalcete e 22% no grupo PTX. Os pacientes tratados com cinacalcete apresentaram melhor função renal (creatinina 1,2 ± 0,3 v.s. 1,7 ± 0,7 mg/dL, p < 0,05). Conclusões: O tratamento cirúrgico foi superior ao cinacalcete para corrigir os distúrbios metabólicos do hiperparatireoidismo, apesar de estar associado a pior função renal no longo prazo. Cinacalcete provou ser um medicamento seguro e bem tolerado.

Resumen El magnesio sérico es el "ion olvidado" en la práctica médica: la mayoría de veces no se tiene en cuenta en los estudios clínicos, sus alteraciones tienden a ser ignoradas y su aproximación terapéutica no está definida de forma adecuada. La sintomatologia producto de la hipomagnesemia es inespecífica y su aproximación diagnostica es compleja. Se presenta el caso de una paciente con hipomagnesemia sintomática severa asociada a daño renal por hipercalcemia durante la gestación.
Abstract Serum magnesium is the «forgotten ion¼ in medical practice. Most of the time it is not taken into account in clinical studies, its alterations tend to be ignored and its therapeutic approach is not well defined. The symptomatology produced by hypomagnesemia is nonspecific and its diagnostic approach is complex. We present the case of a pregnant patient with symptomatic hypomagnesemia secondary to renal damage due to hypercalcemia.

El tejido paratiroideo ectópico es una causa frecuente de recurrencia del hiperparatiroidismo (HPT) siendo de 16% en primarios y 14% en secundarios. La localización intratorácica representa el 20-35%, pero solo un 2% requiere una cirugía torácica. El objetivo fue analizar una cohorte de pacientes con diagnóstico de HPT mediastinal operados en un hospital de alta complejidad de Argentina. Se realizó un estudio retrospectivo de todos los operados por HPT entre enero de 2006 y julio 2019 en ese hospital. Se incluyeron aquellos que requirieron acceso torácico por HPT ectópico. En este período se trataron 728 pacientes con HPT primario y secundario. Seis con primario y 3 con secundario requirieron cirugía torácica. Se realizaron 6 videotoracoscopias (VATS) y 3 esternotomías, sin complicaciones graves. Se utilizó biopsia por congelación en todos y dosaje de paratohormona intraoperatoria (PTHi) en 8 casos, que descendió en promedio 65% respecto al valor basal. Se confirmaron 5 adenomas y 4 hiperplasias. La enfermedad paratiroi dea mediastinal representó el 1.65% (12/728), mientras que recibieron tratamiento quirúrgico en nuestra institución 1.24% (9/728). La biopsia por congelación y el descenso de PTHi resultan útiles para confirmar el foco y eventualmente disminuir el riesgo de recurrencia. La VATS es segura pero depende del entrenamiento y de la disponibilidad en el medio asistencial. Si bien el sestamibi es el método con mayor sensibilidad, se propone el uso de 18F-colina PET/TC ante la sospecha de HPT ectópico. La posibilidad de obtener conclusiones basadas en la evidencia requiere de estudios con mayor número de pacientes.
The ectopic parathyroid tissue is a frequent cause of recurrent hyperparathyroidism (HPT), accounting 16% in primary HPT and 14% in secondary cases. Although intrathoracic ectopic glands represent 25-35% of all ectopic cases, only 2% requires thoracic surgery. The aim of this study is to report a case series of patients with ectopic mediastinal HPT treated by thoracic approach in a private institution in Argentina. This is a retrospective analysis from January 2006 to June 2019. All patients diagnosed with ectopic hyperparathyroidism who required a thoracic surgical approach were included. During this period, 728 patients with primary HPT and secondary HPT were treated. Six with primary HPT and 3 with secondary HPT required a thoracic approach. Six video-assisted thoracoscopy surgeries (VATS) and 3 sternotomies were performed. None of them presented serious posoperative complications. Frozen section biopsy was used in all cases. iPTH was measured in 8 cases, with a mean drop of 65% after 15 minutes. Final pathology reports confirmed 5 adenomas and 4 hyperplasias. Our case series reported an incidence of 1.65% (12/728) mediastinal parathyroids, while 1.24% (9/728) received surgical treatment at our institution. Intraoperative frozen section and PTHi are useful to confirm the diagnosis and to avoid recurrences. Although VATS is a safe and efficient treatment option, it depends on surgical training and availability. In terms of diagnostic imaging resources, sestamibi remains the current gold standard. However, 18F-choline PET/CT may arise as a new diagnostic tool. The possibility of obtaining evidence-based conclusions requires studies with higher number of patients.

ABSTRACT We describe a patient with tertiary hyperparathyroidism with history of three episodes of deep vein thrombosis and on rivaroxaban. The patient underwent a subtotal parathyroidectomy, developing cervical hematoma with airway compression. Therefore, emergency surgical decompression was necessary. Later, on the ninth postoperative day, the serum ionized calcium levels were low. Medical team knowledge about preexisting diseases and their implication in the coagulation state are essential conditions to reduce morbidity and mortality of surgeries. However, no reports were found in literature about the association of hypocalcemia with the use of the new class of anticoagulants, which act as factor X inhibitors (Stuart-Prower factor), predisposing to increased bleeding in the immediate postoperative period.
RESUMO Descrevemos um paciente com hiperparatireoidismo terciário com história de três episódios de trombose venosa profunda e em uso de rivaroxabana. O paciente foi submetido a uma paratireoidectomia subtotal, desenvolvendo hematoma cervical com compressão das vias aéreas. Foi necessária descompressão cirúrgica de emergência. No nono dia de pós-operatório, os níveis séricos de cálcio iônico estavam baixos. O conhecimento da equipe médica sobre doenças preexistentes e de sua implicação no estado de coagulação é condição indispensável para a redução da morbimortalidade do procedimento cirúrgico. No entanto, não há relatos na literatura associando hipocalcemia com o uso da nova classe de anticoagulantes que atuam como inibidores do fator X (fator de Stuart-Prower), predispondo ao aumento do sangramento no pós-operatório imediato.

OBJECTIVE@#To explore the genetic basis for a child with neonatal severe hyperparathyroidism.@*METHODS@#Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Whole exome sequencing was carried out to screen potential mutations. Suspected mutation was verified by Sanger sequencing.@*RESULTS@#The proband was found to carry compound heterozygous variants c.179G>A (p.Cys60Tyr) and c.1525G>A (p.Gly509Arg) of the CaSR gene. The c.179G>A variant was derived from her mother and was unreported previously. The c.1525G>A variant was derived from her father and known to be pathogenic.@*CONCLUSION@#The compound heterozygous variants of c.179G>A and c.1525G>A of the CaSR gene probably underlie the disease in the patient. The results of genetic testing has enabled diagnosis and genetic counseling for her family.

Objetivo: Avaliar o perfil clínico e bioquímico de pacientes com e sem HPTS. Metodologia:Estudo transversal e analítico realizado com 93 pacientes com DRC em HD. Os pacientes foram alocados em dois grupos: sem HPTS (Paratormônio: < 300pg/mL) e com HPTS (Paratormônio: ≥ 300pg/mL). Foram verificados os dados socioeconômicos por meio de questioná-rio semiestruturado. Os dados bioquímicos e antropométricos foram obtidos por meio do prontuário de cada paciente. Tam-bém foram coletadas informações quanto ao tempo de HD, tabagismo, diabetes mellitus, hipertensão arterial sistêmica, cardiopatias, atividade física e a razão triglicerídeo/HDL-Coles-terol. Resultados:O gênero feminino apresentou-se prevalente no grupo com HPTS (59,09%, p=0,017). Nos pacientes que não apresentavam HPTS foi detectado maior presença de diabetes mellitus (77,27%, p=0,021). Os pacientes com HPTS diferiram dos pacientes sem HPTS para o hematócrito (p=0,0457), crea-tinina (p=0,0303) e a fosfatase alcalina (p=0,0011). Conclusão:Encontramos diferença ao comparar os grupos quanto aos níveis de hematócrito, creatinina, fósforo e fosfatase alcalina, resultados que podem implicar no estado clínico de indivíduos com HPTS. Essas análises poderão direcionar condutas e estratégias específicas para o acompanhamento da doença e proposta adequada de tratamento, buscando a melhora do quadro clínico e qualidade de vida. (AU)
Objective: To evaluate the clinical and biochemical profile of patients with and without secondary hyperparathyroidism. Methodology: Cross-sectional and analytical study conducted with 93 patients with CKD in HD. The patients were allocated into two groups: without HPTS (Parathyroid hormone: <300pg / mL) and with HPTS (Parathyroid hormone: ≥ 300pg / mL). Socioeconomic data were verified through a semi-structured questionnaire. Biochemical and anthropometric data were obtained from each patient's medical record. Information was also collected regarding HD time, smoking, diabetes mellitus, systemic arterial hypertension, heart disease, physical activity and the triglyceride / HDL-cholesterol ratio. Results: The female gender was prevalent in the group with HPTS (59.09%, p = 0.017). In patients without HPTS, a higher presence of diabetes mellitus was detected (77.27%, p = 0.021). Patients with HPTS differed from patients without HPTS for hematocrit (p = 0.0457), creatinine (p = 0.0303) and alkaline phosphatase (p = 0.0011). Conclusion: We found a difference when comparing the groups regarding hematocrit, creatinine, phosphorus and alkaline phosphatase levels. Results that may imply the clinical status of individuals with HPTS. These analysis may direct specific conducts and strategies for the follow-up of the disease and appropriate treatment proposal, seeking to improve the clinical condition and quality of life. (AU)

ABSTRACT Objective: To define serum parathyroid hormone (PTH) reference values in carefully selected subjects following the recommended pre-analytical guidelines. Subjects and methods: First, 676 adults who would be submitted to thyroidectomy were evaluated. Patients using interfering medications or with malabsorption syndrome, hypomagnesemia, hyper- or hypophosphatemia, hypo- or hypercalcemia, 25-hydroxyvitamin D < 30 ng/dL, estimated glomerular filtration rate < 60 mL/min/1.73 m2, urinary calcium/creatinine ratio ≥ 0.25, thyroid dysfunction, parathyroid adenoma detected during surgery were excluded. The sample consisted of 312 subjects. Results: The median, minimum, maximum, and 2.5th and 97.5th percentiles of the PTH values obtained were 30, 7.2, 78, 10.1, and 52 pg/mL, respectively. Thus, the reference range was 10 to 52 pg/mL. PTH > 65 pg/mL, the upper limit of normal according to the manufacturer of the kit, was observed in only one subject (0.3%). Considering the upper limit proposed by the kit's manufacturer, 1/6 hypercalcemic patients and 4/8 normocalcemic patients with PHPT had normal PTH. Using the upper limit established in this study, only one normocalcemic patient had normal PTH. Thus, the sensitivity of PTH in detecting asymptomatic primary hyperparathyroidism (PHPT) using the values recommended by the kit and established in this study was 64% and 93%, respectively (50% versus 87.5% for normocalcemic PHPT). Conclusion: The upper reference limit of PTH obtained for a rigorously selected sample was 20% lower than that provided by the assay, which increased its sensitivity in detecting PHPT.

BACKGROUND: Impairment of quality of life (QOL) is a key clinical characteristic of patients with end-stage renal disease (ESRD), and can be especially severe in the presence of secondary hyperparathyroidism (SHPT). Despite the proven success of parathyroidectomy (PTX) in controlling biochemical parameters in patients with severe SHPT, evidence is lacking regarding the effects of PTX on various clinical outcomes, including QOL.METHODS: Twenty ESRD patients on maintenance hemodialysis with SHPT who underwent subtotal PTX were included in an observational longitudinal study. All studied patients underwent history-taking, clinical examinations, and laboratory investigations, including a complete blood count and measurements of serum calcium, phosphorus, magnesium, parathyroid hormone (PTH), and albumin levels preoperatively and at 3 months postoperatively. QOL was assessed before surgery and at 3 months after surgery using the Kidney Disease Quality of Life 36-Item Short-Form instrument.RESULTS: After PTX, significant decreases in serum PTH and phosphorus levels were observed, as well as a significant increase in serum magnesium levels. Significant weight gain and improvements of QOL were also detected postoperatively.CONCLUSION: Subtotal PTX seems to be an efficient alternative to medical management in uncontrolled cases of SHPT, as it is capable of controlling the biochemical derangements that occur in hyperparathyroidism. Furthermore, PTX had a beneficial effect on clinical outcomes, as shown by weight gain and improvements in all QOL scales.
