Introduction: We
aimed to investigate whether duration of diabetes and HbA1c levels in patients
with Type 2 diabetes mellitus (DM) are associated with olfactory dysfunction.

Material and Methods: Fifty
patients with prior Type 2 DM diagnoses under antidiabetic treatment were
included to the study. We used the Turkish version of The Brief Smell Identification
Test (B-SIT) including 12 different odorants to test the odor functions of
patients. Age, weight, height, HbA1C levels, duration of diabetes and test
results of the patients participating in the study were recorded and necessary
analysis was performed. p value <0.05 was considered statistically
significant.

Results: There was no significant
correlation between duration of diabetes and HbA1c levels and B-SIT scores.

Conclusion: In
order to confirm our findings further studies with larger sample sizes, with
patients with longer duration of DM are needed.

TİP 2 DİYABETLİ HASTALARDA DİYABET SÜRESİ VE HBA1C DÜZEYLERİ İLE OLFAKTÖR DİSFONKSİYON ARASINDAKİ İLİŞKİ, PİLOT ÇALIŞMA

Öz

Amaç: Bu çalışmada Tip 2 diyabetes mellitus (DM) tanısı olan hastaların
diyabet süreleri ve HbA1c seviyelerinin olfaktör disfonksiyon ile ilişkili olup
olmadığını araştırmayı amaçladık.

Hastalar ve Yöntem: Önceden bilinen Tip 2 DM tanısı alan ve bu nedenle ilaç
kullanan 50 hasta çalışmaya dahil edildi. Hastaların koku fonksiyonlarını test
etmek için 12 farklı koku maddesi bulunan The Brief Smell Identification Test
(B-SIT) Türkçe versiyonu kullandı. Çalışmaya katılan hastaların yaş, kilo, boy,
kilo, HbA1C seviyeleri, diyabet süreleri ve
test sonuçları kaydedilerek gerekli analiz yapıldı. p
değeri <0.05 istatistiksel olarak anlamlı kabul edildi.

Bulgular: Diyabet süresi ve HbA1c düzeyleri ile B-SIT skorları arasında anlamlı
korelasyon saptanmadı.

Sonuç: Daha uzun süreli
DM’si olan hastalarla yapılacak çalışmalara ihtiyaç vardır.
