    Hepatit C virüsü karaciğerde kronik hasar meydana getiren ve persistan enfeksiyon yapan bir virüstür. HCV enfeksiyonunun önemli ölçüde kronikleşerek ciddi karaciğer yetmezliği ve hepatoselüler karsinoma (HSK)&#8223;ya yol açması ve karaciğer nakli gerektirmesi değil, hastalığın sinsi seyretmesi, klinik belirti vermemesi ve enfekte kişilerin toplumda bir rezervuar oluşturması da onu farklı ve önemli kılmaktadır. Kronik kepatit C hastalarında kantitatif HCV RNA değerinin ve serum transaminaz yüksekliğinin, karaciğer histolojisi ile ilişkisi henüz net bir şekilde açıklanamamıştır. Karaciğerde görülen steatozun fibrozis progresyonuna yol açıp açmadığı bilinmemektedir. Bu çalışmanın amacı; HCV RNA viral yük ve ALT değerlerinin karaciğerdeki steatoz, histolojik aktivite indeksi ve fibroz ile arasındaki ilişkiyi araştırmak ve steatozun karaciğer fibrozisine etkisinin olup olmadığınının araştırılmasıdır. Kronik hepatit C tanısı almış ancak herhangi bir tedavi uygulanmamış 100 hasta çalışma kapsamına alındı. Hastaların serum HCV RNA ve ALT değerleri karaciğer biyopsisinden elde edilen steatoz, nekroinflamatuar aktivite indeksi ve fibrozis skoru ile karşılaştırıldı. Çalışmaya alınan hastaların 63&#8223;ü kadın, 37&#8223;si erkek hastaydı. Yaş ortalaması 55.48 ±11.04 yıl idi. Steatoz değerlendirilmesi Kleiner&#8223;e göre yapıldı. Hastaların % 42&#8223;sinin steatoz evresi 0, % 41&#8223;inin steatoz evresi 1, %10&#8223;unun steatoz evresi 2, % 7&#8223;sinin steatoz evresi 3 olarak saptandı. Nekroinflamatuar aktivite indeksi; Ishak&#8223;a göre (0-18) üzerinden değerlendirildi ve hastalar bu skor üzerinden 4 gruba ayrıldı. (1-4) Minimal Kronik Hepatit, (5-8) Hafif Kronik Hepatit, (9-13) Orta Aktiviteli Kronik Hepatit, (13-18) Ağır Aktiviteli Kronik Hepatit. Çalışmamızda, Hafif Kronik Hepatit C Hastalığı % 70.7 ile en çok görülen karaciğer hastalığı idi. Minimal Kronik Hepatit C Hastalığı% 14.1, Orta Aktiviteli Kronik Hepatit C Hastalığı % 14.1, ve Ağır Aktiviteli Kronik Hepatit C Hastalığı % 1 oranında görülmüştür. Hastaların karaciğer fibrozis skorlaması Ishak&#8223;a göre yapıldı ve hafif fibrozis % 74.7 ile en çok görülen fibrozis idi. % 18.2 oranında hastada orta şiddette fibrozis görüldü, % 7.1 oranında hastada ağır şiddette fibrozis görüldü. Çalışmamızda; HCV-RNA viral yük ile steatoz evresi arasında negatif korelasyon bulundu ( p<0.05). HCV-RNA ile ALT, nekroinflamatuvar aktivite indeksi ve karaciğer fibrozisi arasında istatistiksel anlamlı ilişki bulunmadı. Çalışmamızda; ALT ile nekroinflamatuar aktivite indeksi ve karaciğer fibrozis skoru arasında pozitif korelasyon bulundu (p<0.05). ALT ile HCV RNA ve steatoz arasında istatistiksel olarak anlamlı bir ilişki bulunmadı. Çalışmamızda; steatoz ile nekroinflamatuar aktivite indeksi ve karaciğer fibrozisi arasında istatistiksel anlamlı bir ilişki bulunmadı. Serum ALT düzeylerinin karaciğer hasarının (nekroinflamatuar aktivite ve fibroz skoru) önemli bir göstergesi olduğunu, serum ALT değerlerinin karaciğer biyopsisine karar verme ve kronik C hepatitli hastalarda tanı ve tedavi ihtiyacı konusunda yönlendirici olabileceğini düşünmekteyiz. HCV RNA viral yükün karaciğer histolojisini etkileyen bir parametre olmadığını düşünmekle birlikte bu konuda daha geniş çalışmaların yapılmasının patogenez açısından önemli olacağını düşünmekteyiz. Steatozis kronik hepatit C hastalarında sıklıkla görülen bir histopatolojik bulgudur ancak karaciğer fibrozisine ilerlemesinde steatozun bir katkısının olmadığı görüşündeyiz. Ancak steatoz ile karaciğer fibrozisi arasındaki ilişkinin değerlendirildiği çalışmalara daha fazla ihtiyaç vardır.Hepatitis C is a virus that creates a chronic damage in the liver and causes persistent infection. What makes this illness different and important is not only that it causes liver deficiency, hepatocelluler carcinoma (HCC) and requires a new liver by becoming chronic at a high degree but also that it proceeds insidiously, has no clinic symptoms and infectious people create a reservoir in public. The relation of the chronic Hepatitis C patients&#8223; quantitative HCV RNA values and serum transaminase elevation liver histology hasn&#8223;t been clearly explained yet. Whether the steatosis seen in the liver causes fibrosis progress or not is not known yet. The aim of this study is to examine the relation between the values of HCV RNA viral load and ALT, steatosis, histologic activity index and fibrosis in liver and to search whether steatosis contribute the liver fibrosis or not. 100 patients, who were diagnosed as chronic hepatitis C but were not treated, were examined within the research. The patients&#8223; HCV RNA and serum ALT values were compared with steatosis derived from liver biopsy, necroinflamature activity index and fibrosis score. 100 patients including 63 women and 37 men got included in the study. The average age was 55.48 ± 11.04 years. Steatosis evaluation was made according to Kleiner. Steatoz staging is evaluated as; 33 %-66 % stage 2, >66 % stage 3. % 42 of the patients&#8223;s steatosis staging was established as 0 and % 41 of them was as stage 1 steatoz, % 10 of them was stage 2 steatoz, % 7 of them was stage 3 steatosis. Necroinflammatory activation index; periportal or periceptal interface hepatit (1-4), confluent necrosis (0-6), focal necrosis, apoptosis and focal inflammation (0-4), portal inflammation (0-4). The Necroinflammatory activation index was evaluated out of 18; according to this 1-4 were assessed as Minimal Chronic Hepatitis, 5-8 Light Chronic Hepatitis, 9-13 Medium Activated Chronic Hepatitis, 13-18 Heavy Activated Chronic Hepatitis. As a result of the statistical data, Light Chronic Hepatitis C was the most common liver disease with ratio of % 70.7 Minimal Chronic Hepatitis C was seen with % 14.1, Medium Activated Chronic Hepatitis C % 14.1, and Heavy Activated Chronic Hepatitis C % 1. The fibrosis score of the patients are evaluated as 0 fibrosis is absent, 1-2 is light fibrosis, 3-4 is medium fibrosis, 5-6 is heavy fibrosis. As a result of the statistical data light fibrosis was the most common fibrosis with the ratio of % 74.7 and medium fibrosis % 18.2 and heavy fibrosis % 7.1 . In the correlation tests, negative correlation was found between HCV-RNA and steatosis. Between HCV RNA and steatosis, there is a meaningful difference statistically ( p<0.05). HCV-RNA and ALT, between the necroinflammatory activation index and fibrosis, there is not a significant difference statistically. In the correlation tests, a positive correlation was found among ALT, NIA index and fibrosis and it was accepted statistically significant. (p<0.05). A statistically significant difference could not be found among ALT, HCV RNA and steatosis. A statistically significant difference could not be found among steatosis, NIA and fibrosis in the correlation tests. The fact that serum ALT stages are the indicators of necroinflammatory activation and fibrosis and at the same time the liver damage as well shows that the serum ALT levels are important in determining liver biopsy and it could be leading whether there is a need in the treatment of patients with chronic Hepatitis C is required or not. Although we found that HCV viral load doesn&#8223;t effect liver histology, future studies are needed to define the liver damage pathogenesis. Steatosis is a common seen histopathological finding in CHC however steatosis does not have any effect in the progress of liver fibrosis. More studies, in which the relation between fibrosis and steatosis is evaluated, are needed

    Introduction: The prevalence rates for hepatitis B virus (HBV) and hepatitis C virus (HCV) infections could be affected by the migration of people between countries. The detection of prevalence rates specifi c to individual countries, cities or also hospitals in certain intervals guides the decision-making process required in health policies. According to the data of the Disaster Relief and Emergency Management Agency, there has been a significant flow of immigrants into the province of Kahramanmaras fleeing the civil war in Syria. The aim of this study was to evaluate seroprevalence of HBsAg, anti-HBs, and anti-HCV in serum samples obtained from patients who were admitted to the study center in the last two years. Materials and Methods: The serum samples delivered from all units to our laboratory between January 2013 and October 2014 were tested for HBsAg, anti-HBs, and anti-HCV using an Advia Centaur XP (Siemens, Marburg, Germany) auto-analyzer. Results: A total of 46.356 tests were studied in the scope of this study. Mean ages of the patients tested for HBsAg, anti-HBs, and anti-HCV were 42.7 ± 20.3, 44.1 ± 20.2, and 43.8 ± 20.6 years, respectively. The prevalence of HBsAg between 2013 and 2014 was 5.1% in non-Syrian-origin patients and 3.6% in Syrian-origin patients. The prevalence of anti-HBs was 43.4% among non-Syrian-origin patients and 34.9% among Syrian-origin patients. The prevalence of anti-HCV was 1.2% among non-Syrian-origin patients and 1.8% in Syrian-origin patients. Conclusion: Development of more appropriate health policies is required for refugees since Turkey is allowing the flow of immigrants. Satisfying this need requires the collection of regional data. Thus, this study reported the seroprevalences of HBsAg, anti-HBs, and anti-HCV at our hospital and as far as can be achieved in the literature providing additional information regarding the seroprevalence of HBV and HCV among refugees, who have fled Syria with the escalation of the civil war
