Abstract

Objective: Hepatitis C virus (HCV) is responsible for 20% of acute hepatitis and 70% of chronic hepatitis. Determination of HCV genotype is important in the regulation of treatment and the followup of clinical course. In this study, we retrospectively evaluated the results of test performed in the Central Laboratory of İstanbul Northern Anatolian Association of Public Hospitals to determine the genotype distribution of hepatitis C patients in our region. Materials and Methods: HCV genotypes were determined by real time polymerase chain reaction (Qiagen, Germany) and reverse hybridization line probe assay (Nlm srl, Italy) methods.Results: Among HCV RNA-positive 554 patients, 312 (56.5%) patients had genotype 1b, 127 (23.1%) - genotype 1a, and 94 (17.3%) patients had genotype 3a. A total of 10 samples were identified to be mixed genotype; 3 (0.5%) - genotype 4c/d, 3 (0.5%) - genotype 2a/c, 3 (0.5%) - genotype 1a/1b, and 1 (0.2%) - genotype 1b/4. Conclusion: HCV genotype 1b is the most common genotype in our region similar to country-wide results. However, the rates are lower in our country than in the previous years. Probably the difference in this genotype distribution may depend on globalization, developments in technology, changes in human movements and social behaviors. Genotype determination is important for the regulation of treatment and prognosis of HCV infection

Özet

Amaç: Hepatit C virüsü (HCV) akut hepatitlerin %20'si, kronik hepatitlerin %70'inden sorumludur. HCV'nin genotip tayini tedavide ve klinik sürecin takibinde önemlidir. Bu çalışmada bölgemizdeki HCV genotiplerinin dağılımını belirlemek amacıyla İstanbul Anadolu Kuzey Kamu Hastaneler Birliği Merkezi Laboratuvarı'nda çalışılmış olan test sonuçları retrospektif olarak değerlendirilmiştir.Gereç ve Yöntemler: HCV genotiplerinin tespiti için real time polimeraz zincir reaksiyonu (Qiagen, Almanya) ve reverse hibridizasyon line probe assay metodu kullanıldı (Nlm srl, İtalya).Bulgular: HCV RNA pozitif 554 hastada HCV genotiplerinin prevalansı genotip 1b: 312 (%56,5), genotip 1a: 127 (%23,1), genotip 3a: 94 (%17,3) ve genotip 4c/d: 3(%0,5), genotip 2a/c: 3 (%0,5), genotip 1a/1b: 3 (%0,5), genotip 1b/4: 1 (%0,2) olmak üzere 10 hastada (%1) mix tip olarak tespit edildi.Sonuç: Bölgemizde ülkemizdeki oranlara benzer şekilde HCV genotip 1b en yaygın genotiptir. Ancak oranları ülkemizde önceki yıllarda yapılan çalışmalara göre daha düşüktür. Muhtemelen bu genotip dağılımındaki farklılık, günümüzdeki globalleşme, teknolojideki gelişim, insan hareketlerinin ve sosyal davranışların değişimine bağlı olabilir. Yeni tedavi protokollerinin uygulanabilmesi ve prognozun belirlenmesi açısından HCV hastalarında genotip tayini önemlidir
