Excess Mortality in Acromegaly

I M Holdaway. Horm Res. .

Abstract

Background: Increased production of growth hormone (GH) and insulin-like growth factor-I (IGF-I) in patients with acromegaly is associated with a twofold increase in mortality compared with the general population. The range of standardised mortality rates in various studies ranges from 1.2 to 3.6.

Predictors of mortality: Multivariate analysis has indicated that post-treatment serum GH levels and, in a number of studies, serum IGF-I levels are the most powerful predictors of outcome. Normal IGF-I concentrations and random GH levels <2.5 microg/l measured by polyclonal radioimmunoassay result in optimal outcome. Other factors adversely influencing mortality include hypertension and a long interval between onset of the disorder and diagnosis.

Conclusions: Analysis of recent reports suggests that adoption of treatment guidelines with appropriate post-treatment target ranges for GH and IGF-I, together with the availability of newer methods to control GH oversecretion, has significantly improved patient outcomes.
