dc.description.abstract | Amaç: DR diyabetin en yaygın mikrovasküler komplikasyonudur. Hastalığınpatogenezinde suçlanan faktörler olmasına rağmen kesin nedeni bilinmemektedir,kalıcı tedavisi yoktur. Angiyogenez ile yeni damar oluşumu hastalığınpatofizyolojisinde etkili mekanizmalardan biridir. Çalışmamızın amacı diyabetinyaygın komplikasyonu olan DR'de daha önce beraber çalışılmamış anjiyogenezgöstergeleri olabilecek LRG1, Kallistatin, VEGF, TGFβ düzeylerinin retinopatievreleri ile ilişkisini incelemektir.Gereç ve yöntem: DR gelişmemiş 30 diyabetli, 30 NPDR gelişmiş diyabetli,30 PDR gelişmiş diyabetli ve 30 sağlıklı gönüllüden oluşan kontrol grubu olmaküzere 120 kişi çalışmaya dahil edildi. Çalışmaya katılan tüm hasta ve sağlıklıgönüllelerin serumunda LRG1, Kallistatin, VEGF, TGFβ düzeyleri ölçüldü. Eldeedilen veriler SPSS 21 paket programı kullanılarak analiz edildi.Bulgular: Diyabetik hastalar ve kontrol grubu arasında LRG1, Kallistatin,VEGF, TGFβ düzeylerinde farklılık bulundu (p=0,001). LRG1 ortalaması PDRgrubunda 470,22 ± 18,92 ng/ml, NPDR grubunda 438,74 ± 33,5 ng/ml, DR Olmayandiyabetiklerde 408,9 ± 39,44 ng/ml ve kontrol grubunda 359,9 ± 89,78 ng/ml idi.LRG1 düzeyleri PDR grubunda en yüksek, kontrol grubunda en düşük bulundu. Altgrup analizlerinde LRG1 düzeylerinde; PDR-NPDR arasında (p=0,001), PDR-DROlmayan diyabetikler arasında (p=0,001), PDR-Kontrol arasında (p=0,001), NPDRKontrol arasında (p=0,001), NPDR-DR Olmayan diyabetikler arasında (p=0,002)farklılık saptandı. Kallistatin ortalaması PDR grubunda 608,64 ± 352,45 ng/ml,NPDR grubunda 272,21 ± 240,13 ng/ml, DR Olmayan diyabetiklerde 284,4 ± 222,63ng/ml ve kontrol grubunda 186,0 ± 217,71 ng/ml idi. Kallistatin düzeylerinde PDRgrubu ile kontrol, DR Olmayan diyabetikler ve NPDR grupları arasında farklılıksaptandı (p=0,001). VEGF ortalaması PDR grubunda 378,54 ± 163,63 pg/ml, NPDRgrubunda 247,43 ± 95,62 pg/ml, DR Olmayan diyabetiklerde 252,7 ± 80,06 pg/ml vekontrol grubunda 204,4 ± 79,83 pg/ml idi. PDR grubunda VEGF değeri diğer tümgruplardan yüksekti: PDR-DR Olmayan p=0,003, PDR-NPDR p=0,003, PDRKontrol p=0,001. TGFβ ortalaması PDR grubunda 35,28 ± 14,9 ng/ml, NPDRgrubunda 28,84 ± 5,7 ng/ml, DR Olmayan diyabetiklerde 24,66 ± 9,69 ng/ml vekontrol grubunda 22,24 ± 5,4 ng/ml idi. TGFβ düzeyleri PDR grubunda, DROlmayan diyabetikler ve Kontrol grubuna göre anlamlı yüksekti (p=0,012, p=0,001).NPDR-Kontrol grubu arasında da farklılık saptandı (p=0,001).Sonuç: Angiyogenezde rol aldığı düşünülen biyomarkerların; LRG1,Kallistatin, VEGF, TGFβ; PDR'de plazma seviyelerinde yükselme görüldü. DR'ninerken teşhisinde ve evrelemesinde bu markerlar non-invaziv ve ucuz belirteçlerolarak kullanılabilir.Anahtar kelimeler: DR, PDR, LRG1, Kallistatin, VEGF, TGFβ | |
dc.description.abstract | Purpose: DR is the most common microvascular complication of diabetes.Although there are accused factors in the pathogenesis of the disease, the exact causeis unknown and there is no permanent treatment. New vessel formation withangiogenesis is one of the effective mechanisms in the pathophysiology of thedisease. The aim of our study is to examine the relationship between the levels ofLRG1, Kallistatin, VEGF, TGFβ, which may be indicators of angiogenesis that havenot been studied before in DR, which is a common complication of diabetes, withretinopathy stages.Materials and Methods: 120 people were included in the study, includingDR undeveloped 30 diabetic patients, 30 diabetic patients with NPDR, 30 diabeticpatients with PDR and control group of 30 healthy volunteers. LRG1, Kallistatin,VEGF, TGFβ levels were measured in the serum of all patients and healthyvolunteers participating in the study. The data obtained were analyzed using SPSS 21package program.Results: There was a difference in LRG1, Kallistatin, VEGF, TGFβ levelsbetween diabetic patients and control group (p=0.001). LRG1 mean was 470.22 ±18.92 ng/ml in the PDR group, 438.74 ± 33.5 ng / ml in the NPDR group, 408.9 ±39.44 ng / ml in the Non-DR diabetics and 359,9 ± 89.78 ng/ml in the control group.LRG1 levels were highest in the PDR group and lowest in the control group. Insubgroup analysis, there was a difference between LRG1 levels; between PDRNPDR (p=0.001), between PDR-Non DR diabetics (p=0.001), between PDR-Control(p=0.001), between NPDR-Control (p=0.001), NPDR-Non DR diabetics (p=0.002).Kallistatin mean was 608.64 ± 352.45 ng/ml in the PDR group, 272.21 ± 240.13ng/ml in the NPDR group, 284.4 ± 222.63 ng/ml in the Non-DR diabetics, and 186,0± 217,71 ng/ml in the control group. There was a difference in kallistatin levelsbetween PDR group and control, Non-DR diabetics and NPDR groups (p=0.001).VEGF mean was 378,54±163,63 pg/ml in PDR group, 247,43±95,62 pg/ml in NPDRgroup, 252,7±80,06 pg/ml in Non-DR diabetics and 204,4±79.83 pg/ml in controlgroup. In the PDR group, VEGF value was higher than all other groups: PDR- NonDR p=0.003, PDR-NPDR p=0.003, PDR-Control p=0.001. Mean TGFß was 35.28 ±14,9 ng/ml in PDR group, 28.84 ± 5,7 ng/ml in NPDR group, 24.66 ± 9,69 ng/ml inNon-DR diabetics and 22.24 ± 5,4 ng/ml in control group. TGFß levels weresignificantly higher in the PDR group than in the Non-DR diabetics and controlgroup (p=0.012, p=0.001). There was also a difference between NPDR-control group(p=0.001).Conclusion: Biomarkers thought to play a role in angiogenesis; LRG1,Kallistatin, VEGF, TGFβ; An increase in plasma levels was observed in PDR. Thesemarkers can be used as non-invasive and cheap markers in early diagnosis andstaging of DR.Key words: DR, PDR, LRG1, Kallistatin, VEGF, TGFβ | en_US |
