Evaluation of Serum Uric Acid Level in Type 1 Diabetes Mellitus Patients and Investigation of the Relationship Between Uric Acid Level and Microvascular Complications

Abstract

Type 1 diabetes mellitus (T1DM) is a chronic metabolic disease that develops due to damage to beta cells in the pancreas and is characterized by insulin deficiency. Nephropathy, retinopathy, and neuropathy are known microvascular complications of diabetes. There are few studies evaluating serum uric acid (SUA) levels in T1DM patients, and the relationship of SUA level with microvascular complications is controversial. In the current study, we aimed to evaluate the SUA level in T1DM patients and investigate the relationship between SUA and microvascular complications. The present study was conducted by retrospectively evaluating the files of 160 patients and 85 healthy controls who followed up with a diagnosis of T1DM over the age of 18. The SUA level was lower in T1DM patients than in the control group (p: 0.035), and a negative correlation was found between the SUA level and HbA1c (r:-0.172, p: 0.03). There was a positive correlation between SUA and creatinine level (r: 0.269, p: 0.001). The SUA level was found to be higher in patients with nephropathy regardless of the duration of diabetes (r2: 0.185, p: 0.027). Elevated SUA level was not found as an independent risk factor in patients with neuropathy and retinopathy. In conclusion, although there was a lower SUA level in T1DM patients than in the control group, SUA level was elevated in patients with diabetic nephropathy. Further prospective studies are required to determine whether elevated SUA level is a risk factor for the development of diabetic nephropathy.

Tip 1 Diabetes Mellitus Hastalarında Serum Ürik Asit Düzeyinin Değerlendirilmesi ve Ürik Asit Düzeyinin Mikrovasküler Komplikasyonlar ile İlişkisinin İncelenmesi

Abstract

Tip 1 diabetes mellitus (T1DM) pankreasta bulunan beta hücrelerinin hasarı sonucu gelişen ve insülin eksikliği ile karakterize kronik metabolik bir hastalıktır. Nefropati, retinopati ve nöropati diyabetin bilinen mikrovasküler komplikasyonlarıdır. T1DM hastalarında serum ürik asit (SÜA) düzeyini değerlendiren az sayıda çalışma mevcuttur ve SÜA düzeyinin mikrovasküler komplikasyonlar ile ilişkisi tartışmalıdır. Bu çalışmada T1DM hastalarında SÜA düzeyini değerlendirmeyi ve SÜA düzeyinin mikrovasküler komplikasyonlar ile ilişkisini incelemeyi amaçladık. Bu çalışma 18 yaşından büyük T1DM tanısı ile takipli 160 hastanın ve 85 sağlıklı kontrolün dosyalarının retrospektif değerlendirilmesi ile yapıldı. T1DM hastalarında kontrol grubuna göre SÜA düzeyi düşük bulundu (p:0.035) ve SÜA düzeyi ile HbA1c arasında negatif kolerasyon saptandı (r:-0.172, p:0.03). SÜA ile kreatinin düzeyi arasında pozitif kolerasyon saptandı (r:0.269, p:0.001). Nefropati gelişen hastalarda SÜA düzeyi diyabet süresinden bağımsız olarak yüksek saptanırken (r2:0.185, p:0.027) nöropati ve retinopatisi mevcut olan hastalarda SÜA yüksekliği bağımsız bir risk faktörü olarak saptanmadı. Sonuç olarak T1DM hastalarında kontrol grubuna göre daha düşük SÜA düzeyi bulunmasına rağmen diyabetik nefropati gelişen hastalarda SÜA düzeyinin yüksek olduğu saptandı. Yüksek SÜA düzeyinin diyabetik nefropati gelişiminde risk faktörü olup olmadığını belirlemek için daha ileri prospektif çalışmalar gereklidir.
