Primary hyperparathyroidism (PHPTH) is a common endocrine disorder and it is estimated that 10% of cases are hereditary, related to syndromes including; multiple endocrine neoplasia (MEN) type 1, MEN type 4, MEN2A and hereditary hyperparathyroidism jaw tumour syndrome. Further hereditary cases can occur in the absence of syndromic features such as familial hypercalcemia hypocalcuria. Identifying cases of hereditary PHPTH enables a personalised medicine approach. Current guidel...

The 4th International Workshop for the management of asymptomatic PHPT included the presence of hypercalciuria (dUCa> 400 mg/day) and increased stone risk by biochemical stone risk profile as criteria for surgery. Our aim was to evaluate the complete stone risk profile in 176 consecutive patients with asymptomatic PHPT. We recorded clinical and biochemical data, including 24 hours urinary measurements of the following parameters: volume and pH, creatinine, calcium, magnesi...

Epigenetic deregulation is emerging as a component of the parathyroid tumorigenesis. We identified a long non-coding RNA (LNCRNA) signature clearly distinguishing parathyroid adenomas (PAds) and carcinomas from normal glands. Among the deregulated LncRNAS, HAR1B was upregulated in PAds harboring the common chromosome 11q loss of heterozygosity (Chr11q-LOH; n=10) compared with PAds harboring normal chromosome 11 haplotype (Chr11q-WT; n=12; P&...

Background: Prior small studies have suggested increased risk of infections in patients with hypoparathyroidism (HypoPT). This study using a large managed care cohort evaluated whether chronic HypoPT is associated with increased risk of sepsis, respiratory infections, and kidney or other genitourinary (GU) infections.Methods: A retrospective cohort study using a US commercial claims database (Q1 2007–Q2 2017) was conducted to examine the association...

Patients (pts) with hypoparathyroidism (HypoPT) are at risk to develop renal failure possibly caused by hypercalciuria and nephrocalcinosis. We retrospectively evaluated the data of 711 Patients with HypoPT in 3 endocrine centres in Germany.Methods: Records of 711 pts with HypoPT were reviewed. Patients were predominantly female (n=592, male: n=119; age 50.9±14.1 years, range 12 – 99 years). The following parameters were docum...
