Giriş: Obezitenin tek başına ateroskleroz için bir risk faktörü olduğu
bilinmektedir. Obezite ve ateroskleroz ilişkisi ile ilgili bilinen başlıca
faktörler dislipidemi, insülin rezistansı ve insülin duyarlılığını artırıcı bir
adipositokin olan adiponektin (ADPN) eksikliğidir. Bu çalışmada, obez
çocuklarda adiponektin düzeylerinin araştırılması ve adiponektin düzeyleri ile
ateroskleroza yatkınlık oluşturduğu bilinen başka faktörlerin ilişkilerinin
değerlendirilmesi amaçlanmıştır.

Gereçler ve yöntem: 30 obez çocuk hastanın ve 28 sağlıklı çocuğun plazma
örneklerinden ADPN, plazminojen aktivatör inhbitor-1 (PAI-1), lipid profili, insülin
ve tam kan örneklerinden hemoglobin A1c (HbA1c) düzeyleri belirlendi ve bu
faktörlerin birbirleri ile ilişkileri araştırıldı. Obez hasta grubunda oral
glukoz tolerans testi (OGTT) uygulandı ve OGTT’nin 2. saatinde ADPN ve PAI-1 düzeyleri
tekrar değerlendirildi.

Sonuçlar: Obez hasta grubunda, bazal ADPN ve PAI-1 düzeyleri, OGTT’nin
2. saatinde elde edilen değerlere göre daha düşük tesbit edildi. Bazal ADPN
düzeyleri, vücut kitle indeksi, trigliserid düzeyleri, çok düşük dansiteli lipoprotein
(VLDL) ve insulin düzeyleri ile negatif korelasyon göstermekteydi. Postprandial
elde edilen ADPN ve PAI-1 bazal değerlere göre anlamlı olarak yüksek tespit
edildi. Postprandial PAI-1 ve yüksek dansiteli lipoprotein (HDL) arasında ve
postprandial ADPN ile insulin ve trigliserid düzeyleri arasında negatif
korelasyon tesbit edildi. Trigliserid ve insulin düzeylerindeki değişiklikler
ADPN’i negatif yönde etkilerken, HbA1c’deki değişiklikler pozitif yönde
etkilemekteydi.

Sonuç: Çalışmamız plazma ADPN düzeylerinin atheroskleroz yatkınlığını
gösteren bir belirteç olarak kullanılabileceğini ortaya koymaktadır.

Introduction: It is known that obesity itself is a risk factor for
atherosclerosis. Dyslipidemia, insulin resistance and the deficiency of the
adiponectin (ADPN), which is an adipocytokine increasing the insulin
sensitivity, are the main factors known for their relations with the obesity
and atherosclerosis. This study aimed to determine the levels of plasma ADPN in
obese children and its relationship with several other factors associated with
atherosclerosis.

Materials and Method: Plasma levels of ADPN, plasminogen activator
inhbitor-1 (PAI-1), lipids and insulin and blood hemoglobin A1c (HbA1c) levels
were measured and their relations with each other were determined in 30 obese
and 28 healthy children. Oral glucose tolerance test (OGTT) was performed to
obese children and ADPN and PAI-1 levels were rechecked at the second hour of
OGTT.

Results: In obese children, the basal ADPN and PAI-1 levels were lower, than
their levels obtained 2 hours after the OGTT. Basal ADPN levels showed negative
correlation with the body mass index, and triglyceride, very low density
lipoprotein (VLDL) and insulin levels. Negative correlation was also detected
between the postprandial PAI-1 and high density lipoprotein (HDL), and between
plasma ADPN and insulin and triglyceride levels. While the changes in
triglyceride and insulin levels negatively affected the ADPN, the changes in
HbA1c affected ADPN positively.

Conclusion: Our study indicates that, plasma ADPN level can be used as a
follow up marker for atherosclerosis.
