Background: Good results have been reported with combined use of octreotide
and bromocriptine in acromegalic Caucasians. Data concerning the efficacy
and tolerability of this combination treatment in Chinese acromegalic patie
nts are scanty.
Aim: The aim of this study was to assess the efficacy and tolerability of c
ombined therapy using bromocriptine and octreotide in the treatment of acro
megaly in Chinese patients and to compare the cost-effectiveness of various
regimes.
Methods: Sixteen Chinese acromegalic patients with growth hormone (GH) conc
entration not suppressible to below 5 mU/L (2 mu g/L) during an extended OG
TT were recruited to undergo four phases of the study. During the study per
iod, the patients were given bromocriptine alone, bromocriptine and low dos
e octreotide, bromocriptine and medium dose octreotide, and medium dose oct
reotide alone. Plasma concentrations of GH and insulin-like growth factor-1
(IGF-1) were measured before and after the completion of each phase.
Results: The number of patients reaching target GH concentrations was signi
ficantly higher when treated with octreotide compared to baseline (p<0.05).
Bromocriptine alone had a significant effect but not to the extent of octr
eotide alone. A combination of low dose octreotide and bromocriptine is as
efficacious in the treatment of acromegaly as high dose octreotide. None of
the patients suffered from serious adverse effects.
Conclusion: The results confirmed the usefulness and tolerability of bromoc
riptine and octreotide in Chinese acromegalics. The most cost-effective reg
ime in this study was a combination of low dose octreotide and bromocriptin
e.
