Abstract
Objective
High levels of insulin-like growth factor 1 (IGF-1) in patients with acromegaly cause structural and functional changes specific to the disease. These changes lead to mortality if the disease is not treated. Circadian blood pressure (BP) rhythm as measured by 24-h ambulatory blood pressure monitoring (ABPM) can change with a decrease in BP during sleep and a sudden increase in wakefulness.
Aim
We aim to evaluate the relationship between changes in BP and IGF-1 levels in patients with acromegaly.
Methods
Patients who were diagnosed with acromegaly and the patient group with hypertension were included. Serum biochemistry parameters, serum IGF-1 level and ABPM follow-ups were compared in these patients.
Results
In our study, 30 patients with acromegaly and 30 patients with hypertension without acromegaly were included. Thirty of the patients were male and 30 were female. There was a statistically significant difference between the groups in terms of IGF-1(p = < 0.001) and GH(p = 0.004). There was no significant difference between patients' office systolic/diastolic BP measurements, day/night, systolic/diastolic BP measurements and all systolic/diastolic BP measurements in ambulatory blood pressure follow-ups. There was a significant difference in morning blood pressure surge(p = < 0.001). A statistically significant difference was found between the acromegaly patient groups with MBPS below and above 25 mmHg in terms of IGF-1 (p = 0.025) and platelet levels (p = 0.004).
Conclusion
As a result, cardiovascular disease risks can be predicted in patients with high serum IGF-1 levels by planning ambulatory blood pressure in the early period.
