title: Increased mortality and morbidity in mild primary hyperparathyroid patients. The Parathyroid Epidemiology and Audit Research Study (PEARS).
abstract: OBJECTIVE
  To describe mortality and disease-specific morbidities in patients with mild primary hyperparathyroidism (PHPT).
  
  
  METHODS
  Retrospective population-based observational study.
  
  
  METHODS
  Tayside, Scotland, from 1997 to 2006.
  
  
  METHODS
  Patients with mild PHPT were selected from a predefined PHPT cohort between 1997 and 2006.
  
  
  METHODS
  Standardised mortality ratios (SMRs) were examined for all-cause mortality, as well as cardiovascular and cancer mortality. Standardised morbidity ratios and standardised incidence ratios were also calculated for eleven observed co-morbidities.
  
  
  RESULTS
  In total, there were 1683 (69.1% female) patients identified with mild PHPT in Tayside. Patients were found to have an increased risk of all-cause mortality and cardiovascular mortality (SMR-all cause 2.62, 95% CI 2.39-2.86; SMR-cardiovascular 2.68, 95% CI 2.34-3.05). Patients with mild PHPT had a significantly increased risk of developing cardiovascular and cerebrovascular disease, renal dysfunction and fractures compared to the age- and sex-adjusted general population.
  
  
  CONCLUSIONS
  Mortality and morbidity were increased for patients with mild untreated PHPT, which is similar to more severe PHPT.
