Abstract

Background: The hepatitis G virus( HGV), also called hepatitis GB virus, as a member of the Flaviviridae family distantly related to hepatitis C virus (HCV), Little is known about the frequency of HGV infection, the nature of the illness, or how to prevent it. What is known is that transfused blood containing HGV has caused some cases of hepatitis. They infect humans, but are not known to cause human disease. This virus can be transmitted efficiently by blood transfusion and by other parenteral mechanisms. Transient and long lasting infections with HGV have been documented in man.Patients and methods: HBs Ag, Anti-HCV IgG and Anti-HGV IgG were detected by Enzyme-Linked Immunosorbent Assay (ELISA).HCV RNA on the other hand, has been detected using PCR technique in the serum of 75 Iraqi patients with chronic liver diseases in comparison to 15 healthy individuals.Results: HGV infection was detected in 25% of blood donors, 30% of chronic hepatitis C, 25% of chronic hepatitis B, and 20% of cryptogenic chronic liver disease. HGV infected patients tended to be younger than non-infected patients but no differences concerning sex, possible source of infection, clinical manifestations, biochemical and virological parameters, or severity of liver lesions were found.Conclusions: The percentage of HGV infection in chronic liver disease seems to be relatively high in our area 19 out of 90cases (21.11%). Infection with HGV does not seem to play a significant pathogenic role in patients with chronic liver disease related to chronic HBV or HCV infection, or in those with cryptogenic chronic liver disease. Key words: HGV, chronic liver disease, blood donors.

Abstract

Background: Anti-cyclic citrullinated peptide (anti-CCP) antibodies are highly specific for RA, but are not detectable in all RA patients, in addition their usefulness to identify rheumatic arthritis (RA) from other rheumatic diseases presenting with joint pain is not well studied.Objective: To establish whether the clinical phenotypes of anti-CCP positive and negative disease are distinct at the earliest clinically apparent phase of disease and to assess the diagnostic accuracy of the anti-CCP antibodies assay to separate RA patients from a group of patients with (SLE).Patients and Methods: One hindered ten blood samples were collected from patients, 75 with RA (58 seropositive and 17 seronegative) and 35 patients with SLE attending the Rheumatology Clinic of the Al-Yarmook Teaching Hospital for period between March 2009 and November of 2010 were included in this study. Then sera were stored at -20° and tested for anti-CCP antibodies by a commercially available enzyme-linked immunosorbent assay (ELISA) kit (Euroimmun, while CRP and Rheumatoid factor was test by latex agglutination (LA). Results: Forty five of 58 seropositive RA patients (77.6%) were positive for anti-CCP, while 13 patients tested negative for anti-CCP antibodies. Among the seronegative group, antibodies to anti-CCP could be demonstrated in 22.4% of patients. Anti-CCP positive patients were rheumatoid factor positive (77.6% vs. 22.4%, p < 0.005). There was no significant difference in the pattern of joint involvement. In the SLE group, anti-CCP antibody was positive in only 8 of 35 (22.8 %) patients. Conclusions: Patients with and without anti-CCP antibodies present in a similar way, and anti-CCP antibody have high sensitivity for diagnosis of RA.Keywords: Anti-CCP antibodies, C-reactive protein, rheumatoid arthritis, rheumatoid factor, systemic lupus erythematosus.

الخلفية: ان الاضداد المضادة للبيبتيد الحلقي cyclic citrullinated peptide هي عالية التخصص كأجسام مضادة لالتهاب المفاصل الروماتويدي، ولكن لا يمكن كشفها في كل مرضى التهاب المفاصل الروماتويدي، بالإضافة الى ذلك فان فائدتها لتحديد التهاب المفاصل الروماتيزمية (RA) من الأمراض الروماتيزمية الأخرى المصحوبة بآلام في المفاصل لم تدرس جيدا.الاهداف: لتحديد ما إذا كانت الظواهر السريرية للمرض الموجب او السالب لمضادات ال CCP هي مميزة في المرحلة السريرية المبكرة للمرض وتقييم الدقة التشخيصية لفحص الأجسام المضادة المقاومة لل CCPلفصل مرضى التهاب المفاصل الروماتويدي عن مجموعة من المرضى الذين يعانون من (SLE)النتائج: اظهرت النتائج ان خمسة وأربعين من 58 مريضا من المرضى الموجبين مصليا لمرضى التهاب المفاصل الروماتويدي (77.6٪) موجبين ايضا لاضداد الCCP ، في حين أن 13 مريضا ظهروا سالبين لاضداد ال CCP.اما المرضى السالبين مصليا لمرض التهاب المفاصل فقد تبين ان 22,4% منهم هو موجب لاضداد ال CCP. وظهر ايضا ان المرضى الموجبين لاضداد ال CCP هم ايضا موجبين ل rheumatoid factor (0,005>p , 22,4% .vs77,6%)لم تظهر اية فروق معنوية في نمط شمول المفاصل.وظهر في مجموعة ال SLE ان 8 مرضى من 35 مريضا (22,8% ) هم موجبين لاضداد ال CCP.الاستنتاجات: المرضى مع وبدون اضداد ال CCP ظهروا بشكل متشابه وان اضداد ال تمتلك حساسة عالية لتشخيص الامراض الروماتيزمية.
