Özet
Çin’in Wuhan eyaletinde Aralık 2019’da başlayan ilk salgından bu yana, yeni koronavirüs hastalığı (COVID-19) hızla diğer bir çok bölgeye yayıldı ve küresel bir sağlık tehdidi haline geldi. Bazı ülkelerde COVID-19 prevalansı ve mortalitesinde önemli bölgesel farklılıklar bildirilmesi nedeniyle COVID-19 şiddetinin ve mortalite oranlarının bireysel farklılık göstermesinin nedenlerini araştırma ihtiyacı doğmuştur. Konuyla ilgili ACE reseptörü ve ABO polimorfizmleri ile COVID-19 prevelansı ve mortalitesi arasındaki ilişkiyi araştırmayı amaçlayan pek çok çalışma bulunmaktadır. İnterferonların (IFN) antiviral, antitümör ve immünmodilatör etkileri bulunmaktadır. IFN-α/β benzeri antiviral aktiviteye sahip yeni bir IFN sınıfı interferon-lambda (IFN-λ) ailesi veya tip III IFN’ler yakın zamanda keşfedilmiştir. Bu yeni tip IFN’ler tip 1IFN’lera benzer ancak, nispeten daha az etkilidirler.IFN-λ ağırlıklı olarak solunum yolu epitel hücreleri tarafından salgılanır ve solunum yollarında antiviral etkinliğin artmasına yardımcı olur. Interlökin 28B (IL28B) geni interferon lamda 3 (IFN-λ3) olarak bilinen bir proteini kodlamaktadır. Son yıllarda yapılan çalışmalar hepatit C ve hepatit B enfeksiyonları başta olmak üzere birçok viral enfeksiyonda viral klirens, tedaviye yanıt ve komplikasyon oranları ile IL28B gen polimorfizmi arasındaki ilişkiyi ortaya çıkarmıştır. Son bilgiler ışığında IL28B doğal bağışık yanıt ve antiviral etkinlik dinamikleri açısından feedback mekanizmalarının kilit oyuncusu olma adayıdır.
Çalışmamıza 19-88 yaş aralığında 200 COVID-19 tanısı alan hasta ve kontrol grubu olarak 21-84 yaş aralığında 99 COVID-19 negatif hasta dahil edilmiştir. COVID-19 tanılı hastaların klinik semptom ve bulguları oluşturulan standart kriterler baz alınarak hafif, orta, şiddetli ve kritik olarak sınıflandırıldıve IL28B gen polimorfizmleri tanımlanarak birbirleri ve kontrol grubu ile kıyaslandı.Hasta ve kontrol grubundan alınan numuneler Real-time PCR yöntemi ile çalışılarak elde edilen sonuçlar istatistiksel olarak karşılaştırıldı.
Çalışmamızın sonuçlarında şiddetli/kritik hasta grubunda yaş ortalaması, erkek cinsiyet oranları, ek hastalık görülme sıklığı istatistiksel olarak anlamlı düzeyde yüksek bulundu. Hasta ve kontrol grubunda cinsiyet ve yaş dağılımları arasında anlamlı farklılık bulunmadı.IL28B rs12979860 CC genotipi şiddetli/kritik hasta grubunda hafif/orta gruba göre daha yüksek oranda tespit edildi (p<0, 05). IL28B rs8099917 GT genotipi hafif/orta grupta daha yüksek görülürken, TT genotipi şiddetli/kritik hasta grubunda daha yüksek oranlarda tespit edildi (p<0, 05). IL28B rs8099917 GG genotipi kontrol grubunda tespit edilmezken hasta grubunda %8 oranında saptandı (p<0, 05). Kritik grupta; hayatta kalan ve hayatını kaybeden hastaların genotip dağılımları benzer bulundu.
Şiddetli/kritik grupta daha yüksek oranlarda tespit edilen IL28B rs12979860 CC ve rs8099917 TT genotiplerinin klinik seyir açısından olumsuz genotipler olduğu ve rs8099917 GG genotipinin hastalık bulaşında kolaylaştırıcı bir rol oynadığı sonucuna varılmıştır.
Since the first outbreak in China’s Wuhan province that began in December 2019, the novel coronavirus disease (COVID-19) has rapidly spread to many other regions and has become a global health threat.Significant regional differences in the prevalence and mortality of COVID-19 have been reported in some countries, resulting in the need to investigate the reasons for individual variation in COVID-19 severity and mortality rates.There are many studies aiming to investigate the relationship between ACE receptor and ABO polymorphisms and the prevalence and mortality of COVID-19. Interferons (IFN) have antiviral, antitumor and immunomodulatory effects. A new family of IFN-class interferon-lambda (IFN-λ) or type III IFNs with IFN-α/β-like antiviral activity has recently been discovered. These new types of IFNs are similar to type 1 IFNs but are relatively less effective.IFN-λ is predominantly secreted by respiratory epithelial cells and helps to increase antiviral activity in the respiratory tract.The IL28B gene encodes a protein known as interferon lambda 3 (IFN-λ3).Recent studies have revealed the relationship between viral clearance, response to treatment and complication rates and IL28B gene polymorphism in many viral infections, especially hepatitis C and hepatitis B infections.In the light of the latest information, IL28B is a candidate to be a key player in feedback mechanisms in terms of innate immune response and antiviral activity dynamics. Our study included 200 patients diagnosed with COVID-19 between the ages of 19-88 and 99 patients with negative COVID-19 between the ages of 21-84 years as the control group.The clinical symptoms and findings of patients with a diagnosis of COVID-19 were classified as mild, moderate, severe and critical based on standard criteria, and IL28B gene polymorphisms were identified and compared with each other and the control group.The samples taken from the patient and control groups were studied with the Real-time PCR method and the results obtained were statistically compared. In the results of our study, the mean age, male sex ratios, and the incidence of additional diseases were found to be statistically significantly higher in the severe/critical patient group.There was no significant difference between the gender and age distributions of the patient and control groups.IL28B rs12979860 CC genotype was detected at a higher rate in the severe/critical patient group than in the mild/moderate group (p<0.05).While the IL28B rs8099917 GT genotype was higher in the mild/moderate group, the TT genotype was higher in the severe/critical group (p<0.05).While IL28B rs8099917 GG genotype was not detected in the control group, it was detected in 8% of the patient group (p<0.05).In the critical group; Genotype distributions of surviving and deceased patients were found to be similar. It was concluded that IL28B rs12979860 CC and rs8099917 TT genotypes, which were detected at higher rates in the severe/critical group, were unfavorable genotypes in terms of clinical course, and rs8099917 GG genotype played a facilitating role in disease transmission.
