Abstract

Objectives: The role of endoplasmic reticulum (ER) stress in thepathogenesis of hepatitis B virus (HBV) has been reported. However,serum levels of glucose-regulated protein (GRP) 78 which is an ERstress marker both in tissue and circulation have not been reportedyet. This study aimed to evaluate serum GRP78 levels in patientswith chronic HBV infection.Materials and Methods: A total of 60 patients with HBV infectionand 50 control subjects were included in this study. According toHBV-DNA levels, patients with HBV infection were subdivided intolow, mild and high HBV-DNA subgroups (n=20, in each). SerumGRP78 level was measured by ELISA and then correlation analysiswas performed between GRP78 and alanine aminotransferase(ALT), aspartate aminotransferase (AST), HBV-DNA or hepatitis Bsurface antigen (HBsAg).Results: HBsAg levels were significantly higher in each HBVsubgroup compared to controls. ALT and AST levels weresignificantly increased in the high HBV-DNA subgroup. There was nosignificant difference in serum GRP78 level between controls andHBV subgroups and no correlation between serum GRP78 levelsandother variables.Conclusion: As a result of our study, there was no relationshipbetween the serum level of GRP78 and the HBV infectionparameters. Since ER stress is an important mechanism in HBV-related liver injury, other ER stress markers, such as GRP94, mightbe examined in future studies.

Özet

Amaç: Hepatit B virüsünün (HBV) patogenezinde, endoplazmik retikulum (ER) stresinin rolü daha önceden gösterilmiştir. Ancak, hem dokuda hem de dolaşımda bir ER stres belirteci olan glukozla düzenlenen protein (GRP) 78’in serumdaki seviyesi bugüne kadar çalışılmamıştır. Bu çalışmada, kronik HBV enfeksiyonlu hastaların serum GRP78 seviyelerinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Bu çalışma kontrol (n=50) ve HBV (n=60) olmak üzere iki grup ile yapılmıştır. HBV hastaları, HBV-DNA miktarına göre düşük, orta ve yüksek HBV-DNA alt gruplarına (her birinde n=20) bölünmüştür. Serum GRP78 seviyesi ELISA ile ölçülmüş ve arkasından GRP78 ile alanin aminotransferaz (ALT), aspartat aminotransferaz (AST), HBV-DNA veya hepatit B yüzey antijeni (HBsAg) arasında korelasyon analizi yapılmıştır. Bulgular: Kontrol ile kıyaslandığında, her bir HBV alt grubunda HBsAg seviyesi önemli yüksek bulunmuştur. ALT ve AST seviyesindeki artış, yüksek HBV-DNA alt grubunda önemli bulunmuştur. Serum GRP78, hem kontrol hem de HBV alt gruplarında benzer düzeylerde olup, serumdaki değişkenlerle bir korelasyon göstermemiştir. Sonuç: Çalışmamızın sonuçlarına göre, HBV hastalarının parametreleri ile serum GRP78 seviyesi arasında bir ilişki yoktur. ER stresi, HBV ile ilişkili karaciğer hasarında önemli bir mekanizma olduğundan, daha sonraki çalışmalarda GRP94 gibi diğer ER stres belirteçleri incelenebilir.
