TZD use was associated with an increased risk for fractures in women, particularly at ages above 65 yr. Clinicians should be aware of this association when considering TZD therapy so as to appropriately manage and counsel their patients.

Purpose To investigate the association of the thiazolidinediones (TZDs), rosiglitazone and pioglitazone, together and individually on the risk of cardiovascular outcomes and all-cause mortality, using time-updated propensity score adjusted analysis Methods We conducted a retrospective cohort study in a large vertically integrated health system in southeast Michigan. Cohort inclusion criteria included adult patients with diabetes treated with oral medications and followed longitudinally within the health system between January 1, 2000 and December 1, 2006. The primary outcome was fatal and non-fatal acute myocardial infarction. Secondary outcomes included hospitalizations for congestive heart failure, fatal and non-fatal cerebrovascular accidents and transient ischemic attacks, combined coronary heart disease events, and all-cause mortality. Results 19,171 patients were included in this study. Use of TZDs (adjusted hazard ratio [aHR] with propensity adjustment [PA], 0.92; 95% confidence interval [CI] 0.73–1.17), rosiglitazone (aHR with PA, 1.06; 95% CI 0.66–1.70), and pioglitazone (aHR with PA, 0.91; 95% CI 0.69–1.21) was not associated with a higher risk of acute myocardial infarction. However, pioglitazone use was associated with a reduction in all-cause mortality (aHR with PA, 0.60; 95% CI 0.42–0.96). Compared with rosiglitazone, pioglitazone use was associated with a lower risk of all outcomes assessed, particularly congestive heart failure (P = 0.013) and combined coronary heart disease events (P = 0.048). Conclusions Our findings suggest that pioglitazone may have a more favorable risk profile when compared to rosiglitazone, arguing against a singular effect for TZDs on cardiovascular outcomes.

Parathyroidectomy is the treatment of choice for patients with symptomatic PHPT and patients with asymptomatic PHPT who fulfill certain age, bone density, serum calcium, and creatinine criteria. Further research is needed to determine whether patients with prominent cardiovascular and neuropsychiatric manifestations would benefit from such intervention.
