Amaç: Liraglutid, gıda alımına yanıt olarak intestinal L hücrelerinden salgılanan bir inkretin hormon olan glukagon benzeri peptid-1 reseptör agonistidir (GLP‑1 RA). Glukoz bağımlı insülin sekresyonunu uyarır ve hepatik glukagon sekresyonunu azaltır. Ayrıca, mide boşalmasını yavaşlatır ve tokluk hissi sağlar. Obezite tedavisinde kilo verme amaçlı kullanılan ilk GLP‑1 RA'dir. Liraglutidin tiroid fonksiyon testlerine etkisi bilinmemektedir ve bilgimiz dahilinde bu konuda herhangi bir çalışma bulunmamaktadır. Amacımız, liraglutid tedavisi öncesi ve tedaviden 6 ay sonrasındaki tiroid fonksiyon testlerini, diğer biyokimyasal ve hemogram parametrelerini karşılaştırmaktır.
Gereç ve Yöntemler: Burdur Devlet Hastanesi'nde Ocak 2021-Ocak 2023 tarihleri arasında obezite tedavisi nedeniyle en az 6 aydır liraglutide kullanan 18-65 yaş arası hastalar çalışmaya alındı.
Bulgular: Çalışma süresince tiroid hastalığı olmayan ve liraglutid kullanan 51 hasta (39 kadın, 12 erkek) vardı. On iki hasta, tedavinin 6. ayı tamamlanmadan liraglutid kullanımını bıraktı. Ağırlık, vücut kitle indeksi, açlık serum glukozu, hemoglobin A1C (HbA1c), düşük yoğunluklu lipoprotein (LDL), trigliserit ve tiroid uyarıcı hormon (TSH) değerleri tedavinin 6. ayında anlamlı olarak düşüktü. Serbest tiroksin (sT4) ve serbest triiyodotironin (sT3) değerleri benzerdi. Diğer biyokimyasal ve hemogram parametrelerinde tedavi öncesi ve tedavi sonrası 6 ay arasında fark yoktu.
Sonuç: TSH değerlerinde anlamlı azalma ve metabolik parametrelerde düzelme saptadık, ancak tiroid hormon düzeylerinde farklılık yoktu.

Investigation the impact of liraglutide on the thyroid function tests

Aim: Liraglutide is a once-daily glucagon-like peptide-1 receptor agonist (GLP‑1 RA) which is an incretin hormone secreted from intestinal L cells in response to nutritional intake and stimulates glucose-dependent insulin secretion, decreases hepatic glucagon secretion, slows gastric emptying, provides a feeling of satiety and is the first GLP‑1 RA to be indicated for weight loss treatment for obesity. The impact of liraglutide on thyroid function tests is unknown and to the best of our knowledge, there are no studies on this regard. Our aim is to compare thyroid function tests, other biochemical and hemogram parameters before and 6 months after liraglutide treatment.
Material and Methods: The patients, 18-65 years old, who used liraglutide for at least 6 months due to obesity treatment between January 2021 and January 2023 in Burdur State Hospital were included.
Results: There were 51 patients (39 female, 12 male) using liraglutide without thyroid disease during the study period. Twelve patients discontinued liraglutide use before the 6th month of treatment was completed. Weight, body mass index (BMI), fasting plasma glucose (FPG), hemoglobin A1C (HbA1c), low-density lipoprotein (LDL), triglyceride and thyroid-stimulating hormone (TSH) values were significantly lower at the 6th month of treatment. Free thyroxine (FT4) and free triiodothyronine (FT3) values were similar. and there was no difference other biochemical and hemogram parameters between before and 6 months after treatment
Conclusion: We found a significant decrease in TSH values and improvement in metabolic parameters, but no change in thyroid hormone levels.
