Özet
Amaç: Artmış asimetrik dimetil arjinin (ADMA) düzeyleri başta kardiyovasküler sistem olmak üzere birçok sistemde nitrik oksit (NO) düzeylerini azaltarak olumsuz etkilere neden olur. Helicobacter pylori (H. pylori) enfeksiyonun ADMA düzeylerinde artışa neden olduğu bilinmektedir. Bu çalışmanın amacı H. pylori ile enfekte bireylerde eradikasyon tedavisinin ADMA ve diğer metilarjinin metabolizma ürünlerinin serum düzeylerine etkisini değerlendirmek olarak belirlendi.Yöntemler: 14C üre nefes testi ve gaita antijen testlerinin her ikisinde pozitiflik tespit edilen hastalar H. pylori ile enfekte kabul edildi. Hastalara 14 günlük eradikasyon tedavisi (günde 2 kez 40 mg pantoprazol, günde iki kez 1000 mg amoksisilin ve günde iki kez 500 mg klaritromisin) verildi. Eradikasyon tedavisi öncesinde ve eradikasyon sağlanan hastalarda tedaviden 3 ay sonra ADMA, simetrik dimetil arjinin (SDMA) ve N-monometil-L-arjinin (L-NMMA) serum düzeylerinin ölçümü için kan örnekleri alındı. Bulgular: Çalışmaya dahil edilen 45 hastadan 23'ü kadın ve 22'si erkek idi. Hastaların ortalama yaşı 32,48 idi. Hastaların serum ADMA, SDMA ve L-NMMA düzeylerinde eradikasyon tedavisi sonrasında, tedavi öncesine göre anlamlı düzeylerde azalma olduğu görüldü.Sonuç: Bu çalışmada H. pylori eradikasyonu ile plazma ADMA, SDMA ve L-NMMA düzeylerinde anlamlı azalma olduğu gösterildi. H. pylori eradikasyonuna bağlı azalan serum ADMA, SDMA ve L-NMMA düzeylerinin, başta kardiyovasküler sistem olmak üzere bütün sistemlerde oluşturabileceği yararlı etkilerin değerlendirilmesi için geniş çaplı, uzun süreli çalışmalara ihtiyaç vardır
Objective: Increased asymmetric dimethylarginine (ADMA) levels are associated with reduced nitric oxide (NO) levels in many systems, particularly the cardiovascular system, and cause adverse effects. The objective of this study is to evaluate the effect of eradication therapy in patients infected with Helicobacter pylori (H. pylori) on the serum level of ADMA and other metabolic products of methylarginine.Methods: Patients who were found positive both in urea breath tests and stool antigen tests were considered to have H. pylori infection. These patients received eradication therapy for 14 days (twice daily pantoprazole 40 mg, twice daily amoxicillin 1000 mg, and twice daily clarithromycin 500 mg). Blood samples were taken to measure serum ADMA, symmetric dimethylarginine (SDMA), and N-monomethyl-Larginine (L-NMMA) levels before eradication therapy and 3 months after the therapy for patients for whom eradication was achieved. Results: A total of 23 of the 45 patients included in the study were female, whereas 22 were male. The mean age of the patients was 32.48 years. Significant reductions in the serum ADMA, SDMA, and L-NMMA levels of the patients were observed post-eradication therapy versus pre-eradication therapy. Conclusion: This study demonstrated significant reductions in serum ADMA, SDMA, and L-NMMA levels with H. pylori eradication. Further extensive long-term studies are needed to evaluate the positive effects that reduced serum ADMA, SDMA, and L-NMMA levels after H. pylori eradication can have on all systems, particularly the cardiovascular system
