Bu çalışmada D vitamini ile folat, ferritin, B12 vitamini, homosistein ve metilmalonik asit (MMA) düzeyleri arasındaki potansiyel ilişki incelenmiştir.Gereç ve Yöntemler: Kasım 2022 ile Nisan 2023 tarihleri arasında Dahiliye polikliniğimize başvuran 189 yetişkin hastanın (18-65 yaş) laboratuvar sonuçları hastane kayıtlarından retrospektif olarak elde edildi. 18 yaş altı ve 65 yaş üstü, son 3 ay içinde D vitamini replasman öyküsü olan, kanser, akut enfeksiyon, gebelik, böbrek veya karaciğer hastalığı, Çölyak hastalığı gibi malabsorbsiyon veya inflamatuar barsak hastalığı tanısı alan katılımcılar çalışma dışı bırakıldı.Bulgular: D vitamini ile hemoglobin ve ferritin arasında pozitif korelasyon vardı (sırasıyla r=0,219 p=0,003 ve r=0,262 p KW - Ferritin KW - homosistein KW - metilmalonik asit KW - vitamin B12 KW - vitamin D N2 - Aim: It is not well-known whether there is an association between vitamin D and other vitamin levels. In this study, potential interrelation between vitamin D and folate, ferritin, vitamin B12, homocysteine, and methylmalonic acid levels was examined. Material and Methods: Laboratory results of 189 adult patients (18-65 years old) who admitted to our Internal Medicine outpatient clinic between November 2022 to April 2023 were retrospectively retrieved from hospital registry. Participants younger than 18 and older than 65 years old, with a history of vitamin D replacement within 3 months, diagnosed with cancer, acute infection, pregnancy, renal or hepatic disease, malabsorption like Celiac or inflammatory bowel disease were excluded.Results: There was a positive correlation between vitamin D and both hemoglobin and ferritin (r=0.219 p=0.003 and r=0.262 p CR - 1.
