Acromegaly: Awareness among

Health Care Practitioners

Redzuan Zarool Hassan, Marianne S ElstonHelen M Conaglen, John V Conaglen

“I suffered for 10 years at least with symptoms of acromegaly before diagnosis was made. Early diagnosis would have saved me much discomfort.”

Shared Experiences

“I have found myself really angry at his (GP’s) dismissive attitude to a lot of my symptoms over the years…I do believe he should have diagnosed my condition earlier .”

Shared Experiences

“I feel most let down by the ENT specialist …who didn't ask about my hands and feet, and simply diagnosed weak vocal chords and sent me to a speech therapist.”

Shared Experiences

Valuable Insight

Reflection for learning point, what the system lacks

Although rare, acromegaly can impact livelihood significantly

Awareness is important

Background: Acromegaly

GH excess

Pituitary adenoma

Insidious

Non-specific symptoms

Epidemiology

Rare Incidence: 3-4 per million per year

Prevalence: 60 per million Daly et

al. 2006

Delay in diagnosis 5–10 yrs after symptom onset

Rajasoorya et al. 1994

Awareness amongst Healthcare Practitioners

No reduction in delay of diagnosis 1981-2006

Under-recognition of clinical features

Reid et al. 2010

Effects of Acromegaly

4 Ds: Deformity, Disease, Disability & Death

Increased mortality Uncontrolled GH excess: 10 years earlier death

Rajasoorya et al. 1994

Multiple comorbidities Heart disease, stroke, diabetes, arthritis, vision

problems, sleep apnoea

Acromegaly & Body Image study Conaglen, Elston et al. 2015

Questionnaire Paper & online survey 2012-2014 Waikato Endocrine Clinic patients NZ Acromegaly Society members

Aim to identify: Acromegalic signs/symptoms pre-diagnosis Healthcare practitioners the patients

encountered Professional groups that missed diagnosis

Questions Arising from Study

Are facial feature changes more obvious than acral changes, therefore, noticed earlier?

Are facial feature changes less tolerable than acral changes?

Why is this important?

Importance of Early Recognition

GH level normalisation reduces overall mortality risk Holdaway et al. 2008

Appropriate early treatment Prevent progression of disease

Improve quality of life

Population screening using IGF-1 (DETECT Study, 2008) N = 6773 Only 1.85% with elevated IGF-1 Weakness: uneconomical and unnecessary

routing testing increasing patient anxiety

Notable Methods of Early Recognition

Computerized face detection (Miller et al., 2011) Higher accuracy of

detection (Schneider et al., 2011)

Difficult to apply in GP/dental practices

Notable Methods of Early Recognition

Awareness is Key

Simple but practical approach Handouts/publications Awareness campaigns Close relations with local acromegaly

societies Emphasis in medical curriculum

In Summary

Delayed diagnosis for many years

Acral & orofacial features: most common

Shorter duration between onset of orofacial symptoms and diagnosis

Multiple comorbidities

Better awareness needed Especially primary healthcare

practitioners
