Abstract

Amaç: Son dönemlerde, nonfonksiyone adrenal insidentaloma
(NFAİ) saptanma sıklığının artması ve bu kitlelerin henüz rutin metodlarla ölçülemeyen
bazı aktif metabolitleri salgıladığına dair ciddi kuşkular uyandırması sebebiyle,
bu çalışmada NFAİ’lı hastalarda yeni inflamatuvar belirteçler olan ortalama trombosit
hacmi (MPV), trombosit dağılım genişliği (PDW), nötrofil/lenfosit oranı (N/L), platelet/lenfosit
(P/L) oranı ile insülin resistansı ilişkisinin belirlenmesi amaçlanmıştır.

Gereç ve Yöntemler: Çalışmaya Endokrinoloji polikliniğine başvuran
ve NFAİ tanısı konan 60 hasta ve herhangi bir nedenle çekilen üst abdomen bilgisayarlı
tomografi (BT)’de adrenal kitlesi olmayan ve herhangi başka patolojiye rastlanmayan
60 sağlıklı kontrol grubu dahil edildi.

Bulgular: Kontrol grubu ile fonksiyonel olmayan adrenal
insidentaloma hastaları arasında cinsiyet, yaş, antropometrik ölçümler, açlık plazma
glukozu ve lipid profili açısından anlamlı fark yoktu. Ortalama MPV, PDW, N/L
oranı, P/L oranı karşılaştırıldığında
NFAİ’lı hastalarda sağlıklı kontrol grubuna göre istatistiksel anlamlı fark bulunamadı.
NFAİ hastaları, sağlıklı kontrol grubundan daha yüksek açlık insülin seviyesine
(p=0.016) ve HOMA-IR düzeylerine sahipti (p=0.01). HOMA-IR ile MPV, PDW, N/L
oranı ve P/L oranı arasında
hiçbiri ile korelasyon saptanmadı.

Sonuç: NFAİ hastalarda MPV, N/L, P/L oranları gibi yeni
ateroskleroz ve subklinik inflamatuvar markerlarda değişiklik olmadığını gösterdik.
İnsülin direnci NFAİ hastalarında kontrol grubuna göre daha sık gözlenmektedir ve
bu açıdan hastaların yakın takibi gerekmektedir. Bu hastalardaki insülin direncinin
fizyopatolojisini açıklayacak daha ileri prospektif çalışmalara ihtiyaç vardır.

Insulin Resistance in Nonfunctioning Adrenal Incidentaloma and New Inflammatory Markers

Abstract

Objective: Due to the increase of incidence of nonfunctioning
adrenal incidentaloma (NFAI) recently, and the suspicion that these masses secrete
some active metabolites that cannot yet be measured by routine methods, we aimed
to determine the relationships between insulin resistance and new inflammatory markers
such as mean platelet volume (MPV), platelet distribution width (PDW), neutrophil/lymphocyte
ratio (N/L), platelet/lymphocyte ratio (P/L) in patients with NFAI in our study.

Material and Methods: Sixty patients admitted to the endocrinology
outpatient clinic and diagnosed as NFAI and 60 healthy controls without adrenal
mass and no other pathology on upper abdomen computed tomography (CT) for any reason
were included in the study.

Results: There were no significant differences between
control group and patients with NFAI in terms of gender, age, anthropometric measurements,
fasting plasma glucose and lipid profile. The mean MPV, PDW, N/L ratio and P/L
ratio were not significantly
different between healthy control group and NFAI group. The patients with NFAI had
higher fasting insulin level (p=0.016) and
higher HOMA-IR value than their healthy control group (p=0.01). There were no correlations
between HOMA-IR and MPV, PDW, N/L
ratio, P/L ratio.

Conclusion: We demonstrated no difference in new markers of atherosclerosis and systemic inflammation such as MPV, PDW, N/L ratio and P/L ratio in patients with NFAI. Insulin resistance was
more frequent in the patients with NFAI than in controls, therefore, close follow-up
is required. The further prospective studies to explain the
physiopathology of insulin resistance in these patients are needed.
