Limitations <strong>of</strong> Guideline Development<br />

<strong>The</strong> biochemical diagnosis <strong>of</strong> acromegaly and the biochemical monitoring <strong>of</strong><br />

therapy is controversial<br />

Interpretation <strong>of</strong> biochemical results<br />

• Variability between and within assays<br />

• Assays are <strong>of</strong> variable sensitivity<br />

Correlation <strong>of</strong> GH and IGF-1 values and morbidity<br />

outcomes unclear<br />

What are appropriate biochemical goals?<br />

• Epidemiologic studies provide the best evidence for GH and<br />

IGF-1 endpoints<br />

• No clear consensus on how biochemical goals impact on<br />

morbidity endpoints<br />

Limited prospective, controlled studies comparing therapeutic<br />

interventions
