THE CLINICAL PRESENTATION OF PRIMARY HYPERPARATHYROIDISM: A SOUTHERN EUROPEAN PERSPECTIVE OVER THE LAST 2 DECADES.

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.
