With the currently best available therapy (peginterferon and ribavirin) only less than 50% of patients with HCV genotype 1 will respond. Unknown is what factors determine this difference in treatment outcome. Probably virologic and immunologic factors play a major role. By investigating blood samples of HCV / HIV coinfected patients and HCV mono-infected patients we would like to examine both virologic and immunologic factors possibly responsible for this difference.', 'detailedDescription': 'background: each year the Hepatitis C (HCV) and the human immunodeficiency virus (HIV) infect worldwide millions of people. In the western world coinfection of HIV with HCV mainly exists in intravenous drug users. In coinfected patients progression of liver fibrosis to cirrhosis and endstage liver disease is much faster than in patients with only a mono-infection of hepatitis C. With the current treatment regimes response rates differ between HCV genotypes and between coinfected and mono-infected patients. Reasons for this a yet not well understood.\n\nVirology: In the treatment of HCV genotype 1, after 12 weeks treatment success is evaluated (EVR) and if the HCV RNA-load is insufficiently dropped the treatment is stopped. There are indications that this moment of evaluation can be done earlier. Whole blood analysis can be a more sensitive method to determine an earlier EVR.Furthermore there are a few known HCV mutations playing a role in the chronicity of HCV. Lack of treatment response can be caused by other mutations in the HCV genome. Sequencing of the whole HCV genome has not been done very extensively.\n\nImmunology: Proliferation and interferon production by HCV specific CD8 cells is defective. Not very much is known about the HCV-specific CD8 cells responses during treatment with peginterferon and ribavirin. Evidence is gathering that regulatory T-cells (CD4+CD25+) are involved in the process of inhibiting proliferation. Also it is known that the concentration of HCV-specific CD4 and CD8 cells in the liver is higher than in the peripheral blood. Certain homing molecules are probably involved in this process.\n\nHypothesis:\n\nvirologic: 1) at 4 weeks it is possible to determine an EVR; 2) other than the known ,mutations are responsible for the chronicity and unresponsiveness of the HCV virus; 3) whole blood analysis will be able to predict an EVR with more sensitivity than the current HCV-RNA techniques.\n\nimmunologic: 1) the specific relation between HCV specific CD4 and CD8 cells will determine if proliferation and production of interferon during therapy with peginterferon and ribavirin is successful. 2) regulatory T cells are inhibiting proliferation and production in chronic HCV infection and the amount of regulatory T cells will diminish during therapy with peginterferon and ribavirin. 3) wich homing molecules are important in the homing of HCV specific CD8 cells to the liver.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nAll patients where the treating physicians decides to start treatment with peginterferon and ribavirin for treatment of hepatitis C\n\n* HCV mono-infection or HCV / HIV coinfection\n* Genotype 1\n* Compliant for outpatient visits'}, 'identificationModule': {'nctId': 'NCT00150904', 'briefTitle': 'Peginterferon and Ribavirin on Virologic and Immunologic Parameters in Hepatitis C Mono- and Coinfected Patient (PRIVICOP)', 'organization': {'class': 'OTHER', 'fullName': 'UMC Utrecht'}, 'officialTitle': 'Request for Blood Samples to Examine the Effect of Peginterferon and Ribavirin on Virologic and Immunologic Parameters in Patients With Hepatitis C and in Patients Coinfected With Hepatitis C and HIV', 'orgStudyIdInfo': {'id': '04-247E'}}, 'armsInterventionsModule': {'interventions': [{'name': 'venous blood puncture', 'type': 'PROCEDURE'}]}, 'contactsLocationsModule': {'locations': [{'zip': '3584 CX', 'city': 'Utrecht', 'state': 'Utrecht', 'country': 'Netherlands', 'facility': 'University Medical Center Utrecht', 'geoPoint': {'lat': 52.09083, 'lon': 5.12222}}], 'overallOfficials': [{'name': 'I.
