Primary Hyperparathyroidism

Publication date: Available online 28 September 2018Source: Best Practice &Research Clinical Endocrinology &MetabolismAuthor(s): Barbara C. Silva, Natalie E. Cusano, John P. BilezikianAbstractPrimary hyperparathyroidism (PHPT), the most common cause of hypercalcemia, is most often identified in postmenopausal women with hypercalcemia and parathyroid hormone (PTH) levels that are either frankly elevated or inappropriately normal. The clinical presentation of PHPT includes three phenotypes: target organ involvement of the renal and skeletal systems; mild asymptomatic hypercalcemia; and more recently, high PTH levels in the context of persistently normal albumin-corrected and ionized serum calcium values. The factors that determine which of these three clinical presentations is more likely to predominate in a given country include the extent to which biochemical screening is employed, the prevalence of vitamin D deficiency, and whether a medical center or practitioner tends to routinely measure PTH levels in the evaluation of low bone density or frank osteoporosis. When biochemical screening is common, asymptomatic primary hyperparathyroidism is the most likely form of the disease. In countries where vitamin D deficiency is prevalent and biochemical screening is not a feature of the health care system, symptomatic disease with skeletal abnormalities is likely to predominate. Finally, when PTH levels are part of the evaluation for low bone mass, the normocalcemic variant ...

ConclusionSignificant association was found between hypovitaminosis D, osteoporosis and fracture site comminution. High prevalence of hypovitaminosis D in patients presenting with hip fractures and fracture site comminution implicates the necessity for proper evaluation and effective supplementation of vitamin D in elderly patients along with anti-osteoporotic regimens for effective prevention and appropriate management of osteoporotic hip fractures.

We report the results of the first 12 months of operation in patients admitted to the hospital.ResultsFirst acute fragility fracture(s) were identified in 36% (80/223), only historical fragility fracture(s) in 28% (63/223) and both acute and historical fragility fracture(s) in 36% (80/223). The cumulative subgroup with historical fragility fractures with/without new fractures included 67% (96/143) without a previous diagnosis of osteoporosis. First acute fragility fracture group included 83.8% (67/80) without a previous diagnosis of osteoporosis. Rush FLS “captured missed opportunities” in 73.1% (163/223) ...

In this study, we demonstrate that irrespective of the derivation of CD8+ CD45RA+CD27- T cells, these primed cells exhibit a unique highly inflammatory secretory profile characteristic of the SASP, and we also provide evidence that ADAM28 can be used as a functional marker of senescence in CD8+ T cells. Furthermore, we show that the secretory phenotype in CD8+ CD45RA+CD27- T cells is controlled through p38 MAPK signalling, which contributes to age-associated inflammation.

It has been observed that Alzheimer's disease and osteoporosis appear to be correlated to a larger degree than one would expect simply because both emerge, after a long chain of cause and effect, from the root causes of aging. That they are correlated in this way suggests that they share in common some parts of the middle of that long chain. Given that osteoporosis is a condition of the bones, a disruption of the balance between cells that create bone and cells that destroy bone, and Alzheimer's is a condition of the brain, in which aggregated proteins overwhelm cells, what could these two very different outcomes of aging ...

AbstractSummaryRationale: Calcidiol can be employed to correct vitamin D deficiency. Main results: Calcidiol administered at daily and weekly regimens over a period of 3  months was able to successfully raise 25-hydroxyvitamin D levels without altering other markers related to bone and mineral metabolism. Significance: Calcidiol supplementation is effective and safe.IntroductionThe correction of vitamin D status is necessary to maintain an optimal mineral and skeletal homeostasis. Despite cholecalciferol (vitamin D3) is the most commonly used drug for vitamin D supplementation, the more hydrophilic compound calcidiol ...

Conclusion The current study showed that adynamic bone disease is prevalent even in pre-dialysis CKD population. High bone turnover disease may not be the most prevalent type in diabetic CKD. However, it could contribute to the development of osteoporosis in CKD subjects. Serum total ALP can serve as a biochemical marker to identify pattern of bone turnover where intact PTH is not available.

AbstractSummaryLittle is known about the association between vitamin D deficiency and the skeletal phenotypes in primary hyperparathyroidism (PHPT) patients. A low 25-hydroxyvitamin D level was associated with a low bone mineral density and deteriorated hip geometry in women with PHPT in an Asian population where vitamin D deficiency is prevalent.IntroductionFew studies have examined the effect of vitamin D deficiency on the bone health of primary hyperparathyroidism (PHPT) patients.MethodsWe investigated the skeletal effects of vitamin D deficiency in 79 PHPT patients by assessing bone mineral density (BMD), the trabecula...

This study aimed to evaluate vitamin D deficiency and its association with secondary hyperparathyroidism, bone resorption, and bone density in Brazilian men. A total of 120 men, 20 –93 years, were evaluated for serum calcium, phosphorus, creatinine, 25-hydroxyvitamin D (25(OH)D), parathyroid hormone, biochemical markers of bone resorption (carboxy-terminal telopeptide, carboxy-terminal peptide of type I collagen), and bone mineral density (dual-energy X-ray absorptiometry).

This study evaluated bone mineral density (BMD) loss in endocrinopathies [Graves' disease (GD), type 1 diabetes mellitus (T1DM), hypogonadotrophic hypogonadism (HypoH), hypergonadotropic hypogonadism (HyperH), hypopituitarism, primary hyperparathyroidism (PHPT)] as compared to age-related BMD loss [postmenopausal osteoporosis (PMO), andropause]. Materials and Methods: Retrospective audit of records of patients>30 years age attending a bone clinic from August 2014 to January 2016 was done. Results: Five-hundred and seven records were screened, out of which 420 (females:male = 294:126) were analyzed. A significantl...
