Brief Summary

Dopamine agonists are first-line agents for the treatment of prolactinomas (1) and Parkinson's disease (2). There is evidence supporting a causal relationship between the occurrence of drug-induced "restrictive" valvular heart disease and treatment with pergolide (3): in several cases, the valvulopathy improved when pergolide was discontinued (4). Valvular heart damage has also been reported with the ergot-derived dopamine agonists bromocriptine and cabergoline (5,6). Two recent studies (7,8) have further demonstrated that both pergolide and cabergoline are associated with an increased risk of new cardiac valve regurgitation in patients treated for Parkinson's disease. The valvular abnormalities seen with ergot-derived dopamine agonists are similar to those observed in patients receiving ergot alkaloid agents (such as ergotamine and methysergide) in the treatment of migraine, or fenfluramine and dexfenfluramine in the treatment of obesity. These abnormalities also closely resemble carcinoid-related valvulopathies (9). Cardiac valve disease has never been reported in patients with prolactinomas who require treatment with dopamine-agonists even life-long (1). At variance with patients with Parkinson's disease, patients with prolactinomas are younger and are treated with an average dose of dopamine-agonists that is significantly lower (median bromocriptine dose 5 mg/day and median cabergoline dose 1 mg/week). Because of the young age of treatment beginning (most patients with microprolactinomas start dopamine-agonist treatment in early adulthood), treatment might be continued for over 3 decades: the cumulative risk of low doses of dopamine agonists for such a long period of treatment is currently unknown. To assess the prevalence of cardiac valve disease in patients treated with cabergoline, we wish to perform an echocardiography screening in a large representative sample of patients with prolactinoma who were treated with cabergoline for at least 12 months and in a group of control subjects recruited prospectively. We wish to evaluate the severity of regurgitation for the mitral, aortic, and tricuspid valves. Changes in cardiac valve apparatus was compared with treatment duration and cumulative cabergoline dose.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of regurgitation (graded as mild, moderate, severe) at any cardiac valve.

    9 months

Study Arms (2)

1

Patients already receiving treatment with cabergoline.

Drug: Cabergoline

2

healthy controls sex and age-matched with the patients

Interventions

According with our previous studies, in the patients with microprolactinoma and in those with non-tumoral hyperprolactinemia, cabergoline treatment was administered orally at a starting dose of 0.25 mg twice weekly for the first two weeks and then 0.5 mg twice weekly. After 2 months of treatment, dose adjustment was carried out every 2 months on the basis of serum PRL suppression.

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Three different study populations will be studied. * Group 1) Patients already receiving treatment with cabergoline for at least 12 months * Group 2) Newly diagnosed patients with hyperprolactinemia who never received treatment with dopamine-agonists * Group 3) Non hyperprolactinemic subjects matched with the patients for sex and age to be used as controls.

You may qualify if:

  • Patients with documented hyperprolactinemia receiving continuous treatment with cabergoline only for at least 12 months
  • Newly diagnosed patients with prolactinoma never previously receiving dopamine agonists treatment

You may not qualify if:

  • A history of cardiac valve abnormalities,
  • Previous use of anorectic drugs or other ergot-derived drugs,
  • Treatment with cabergoline for less than 12 months,
  • Valve calcification, valve regurgitation associated with annular dilatation or excessive leaflet motion,
  • Mitral regurgitation associated with left ventricular wall-motion abnormalities or left ventricular dilatation,
  • Withdrawal from cabergoline treatment for longer than 1 month, according with our treatment protocol (11).
