Purpose: In our article, we aimed to identify whether there is an increase in intima-media thickness (IMT) measured from the abdominal aorta in patients with acromegaly and to identify the parameters closely related to the aortic IMT (AIMT).

Materials and Methods: 52 patients with acromegaly and 46 healthy controls were included. For all participants, all the necessary laboratory tests were done for acromegaly. On vascular ultrasound examination, the internal carotid IMT, common-carotid IMT, and aortic IMT (AIMT) were measured. The study population was divided into 3 different groups; control group (Group I), acromegaly patients in remission (Group II) and acromegaly patients with active disease (group-III). 

Results: The incidence of hypertension, diabetes, and smoking was higher in Group-II-III than Group I. Insulin-like growth factor-1 (IGF-1) levels were increased from Group I to III and there was a significant difference between all groups. Common-carotid IMT and internal carotid IMT values were not significantly different between the groups. The AIMT value in Group III patients was statistically higher than the other two groups. The AIMT was similar between Groups I to II. Only the IGF-1 level was found to be independently associated with AIMT. 

Conclusion: In patients with active acromegaly disease, AIMT is significantly elevated without elevation of carotid IMT, and AIMT is independently associated with serum IGF-1 levels. AIMT could be a useful study to show the presence of early subclinical atherosclerosis in acromegaly patients.

Amaç: Çalışmamızda akromegali hastalarında abdominal aorttan ölçülen intima-media kalınlığında (IMK) bir artış olup olmadığını ve aort IMK(AIMK) ile yakından ilişkili parametreleri tanımlamayı amaçladık.

Gereç ve Yöntem: Çalışmaya 52 akromegali hastası ve 46 sağlıklı kontrol dahil edildi. Tüm katılımcılara akromegali için gerekli tüm laboratuvar testleri yapıldı. Vasküler ultrason incelemesinde internal karotid IMK, kommon karotid IMK ve AIMK ölçüldü. Çalışmaya dahil edilenler 3 gruba ayrıldı; kontrol grubu (Grup I), remisyondaki akromegali hastaları (Grup II) ve aktif hastalığı olan akromegali hastaları(Grup-III). 

Bulgular: Grup II-III’te hipertansiyon, diyabet ve sigara içme sıklığı Grup I’den daha yüksek saptandı. İnsülin benzeri büyüme faktörü-1 (IBBF-1) düzeyleri Grup I'den III'e doğru yükseliyordu ve tüm gruplar arasında anlamlı fark vardı. Gruplar arasında kommon-karotid IMK ve internal karotid IMK değerleri arasında anlamlı bir farklılık saptanmadı. Grup III hastalarında AIMK değerleri diğer gruplara göre istatistiksel olarak daha yüksek saptandı. AIMK grup I ve grup II hastalarında benzerdi. IBBF-1 düzeyi sadece AIMK ile bağımsız olarak ilişkili saptandı. 

Sonuç: Aktif akromegali hastalığı olanlarda karotid IMK artışı olmadan aortik IMK’da belirgin bir artış olmaktadır ve bu artış serum IBBF-1 düzeyleri ile bağımsız olarak ilişkilidir. AIMK, akromegali hastalarında erken subklinik ateroskleroz varlığını göstermek için yararlı bir çalışma olabilir.
