Brief Summary:
In acromegaly, nearly 40% of patients fail to control GH/IGF-I levels with somatostatin analogues (SA). Dopaminergic agonists (DA) are even less effective, but combination therapy with SA and DA normalizes IGF-I levels in 33-56% of patients in short-term studies. This study was designed to evaluate short and long term efficacy of cabergoline in controlling IGF-I levels in acromegalic patients receiving octreotide.

Group/Cohort Intervention/treatment
Responders to cabergoline
patients with active disease under octreotide treatment received addition of increasing doses of cabergoline (1.0, 2.0 and 3.5mg/week)
Drug: cabergoline
cabergoline doses were increased at 6-week intervals, starting at 1.0mg/week followed by 2.0 and 3.5mg/week. Hormonal evaluations (IGF-I, GH and PRL) started before the first dose and were repeated at 6-week intervals after each cabergoline dose and after cabergoline withdrawal
Other Name: cabergoline-Dostinex

Primary Outcome Measures :
  1. Control of IGF-I levels [ Time Frame: six months ]

Secondary Outcome Measures :
  1. control IGI-I levels [ Time Frame: six months ]

Biospecimen Retention:   Samples Without DNA
serum for IGI-I, GH and prolactin measures
