Abstract (2. Language):
Objective: The probability of developing nocturnal hypoglycemia is high in type 2 diabetic patients with existing
heart failure. We intended to compare applying single dose of glargine insulin by bedtime against twice daily NPH
insulin in terms of creating nocturnal hypoglycemia in such patients.
Material and method: The patients demonstrating similar characteristics with respect to age, body mass index,
duration of diabetes and heart failure and metabolism were randomized into two groups as insulin glargine (n:19)
and NPH (n:11). The subjects have been prospectively followed up for 12 weeks.
Results: The maintenance of metabolic control was found to be markedly better in glargine insulin group than those
being applied NPH (p< 0.001). The frequency of nocturnal hypoglycemia was observed to be 10.5 % in the insulin
glargine group, compared to 9.1 % in the NPH group, which was not a statistically significant difference. The
frequency of overall hypoglycemia was higher in patients taking glargine insulin (p= 0.029).
Conclusions: While the use of insulin glargine provided a better metabolic control in our study group compared to
NPH insulin, it failed to decrease the frequency of nocturnal hypoglycemia. Caution should be taken for nocturnal
hypoglycemia when using insulin in type 2 diabetics with concurrent heart failure.

Abstract (Original Language):
Amaç: Tip 2 diyabetik hastalara kalp yetersizli¤i de efllik etti¤inde gece hipoglisemisi görülme s›kl›¤› artar. Çal›flmam›
zda, bu grup hastalarda günde tek doz glargine insulin tedavisi ile günde 2 kez NPH insulin kullan›lmas›n›n
gece hipoglisemi geliflmesi üzerine etkilerini karfl›laflt›rmay› amaçlad›k.
Gereç ve yöntem: Yafl, vücut kitle indeksi, diyabet ve kalp yetmezli¤i süreleri ve metabolik göstergeler aç›s›ndan
benzer özelliklere sahip hastalar glargine insulin ve NPH insulin tedavi gruplar›na ayr›ld›lar. Hastalar 12 hafta izlendiler.
Bulgular: Glisemik kontrolün glargine insulin uygulanan grupta, di¤er gruptan belirgin olarak daha iyi sa¤land›¤›
gözlendi (p< 0,001). Gece hipoglisemi görülme s›kl›¤› glargine insulin grubunda % 10,5, NPH grubunda % 9,1 olup
istatistiksel olarak farkl› de¤ildi. Genel hipoglisemi oluflma s›kl›¤› ise glargine insulin uygulananlarda fazlayd› (p=
0,029).
Sonuç: Günde tek doz Glargine insulin kullan›m› tip 2 diyabetes mellitusla beraber kalp yetersizli¤i olan hastalar›
m›zda günde 2 kez NPH insulin kullan›m›na göre daha iyi kan flekeri kontrolü sa¤lam›fl olmakla birlikte gece hipoglisemi
görülme s›kl›¤›n› azaltmam›flt›r. Bu nedenle bu grup hastalarda uzun etkili insulin kullan›m›nda gece hipoglisemisi
geliflmesi olas›l›¤› bak›m›ndan dikkatli olunmal›d›r.
