Abstract
Aims:
Biological, psychological and social factors may interact with the mental health status
of Graves’ disease (GD) patients before and after antithyroid drug (ATD) treatment.
Our aim was to quantify the impact of supportive and risk factors after recovery from
GD which may enhance cure rates.
Patients and Methods:
300 patients were recruited for a 6-year prospective cohort study. Before and after
treatment, we assessed the impact of biopsychosocial factors on the success of ATD
treatment and mental health using the Symptom Checklist 90, the Eysenck Personality
Questionnaire, the Life Event Scale, Simplified Coping Styles and the Perceived Social
Support Scale. The patients routinely received ATD at least over 18 months. End-point
was defined as cured (at least 2 years without a relapse after the withdrawal of ATD),
otherwise as not cured.
Results:
Regression analysis explained 80.5% of the influences affecting mental health. The
odds ratios (OR) revealed positive coping styles (OR: 2.90, 95% CI, 1.09–7.68), negative
events (OR: 1.04, 95% CI, 1.01–1.07) and social support (OR: 5.10, 95% CI, 2.77–9.40)
as protective factors, predicting a cure for GD patients. These variables explained
61.7% of the influences leading to a cure or no cure. Large thyroid volume was a risk
factor, predicting failure (OR: 0.865, 95% CI, 0.83–0.90, P<0.000).
Conclusions:
Enhancing positive coping strategies and social support is important to improve mental
health in GD patients, to avoid compromising work-related performance and endangering
a patient’s social status.
