BACKGROUND The current stopping rule for peginterferon/ribavirin therapy in hepatitis C virus genotype-1 (HCV-1) patients is based on an early virological response (EVR, defined as >2 log(10) viral reduction at treatment week 12). We aimed to explore rapid stopping rules at week 4. METHODS We randomly allocated 528 HCV-1 patients into training and validation sets (at a 1∶2 ratio). The interle...
BACKGROUND Hepatitis C virus infection is a global health problem. New direct-acting antiviral agents have been recently approved. However, due to their high cost and some genotypes remaining difficult to treat, interferon-based therapy with pegylated interferon and ribavirin likely may remain a component of hepatitis C virus treatment for some patients. Unfortunately, pegylated interferon / ri...
The role of the hepatitis C virus (HCV) NS3/4A protease in ablating the signaling pathway involved in the production of alpha/beta interferon (IFN-α/β) suggests a relationship between NS3/4A proteolytic activity and a patient's response to IFN-based therapy. To identify viral factors associated with the HCV treatment response, we analyzed the pretreatment NS3/4A protease gene quasispecies compo...
سابقه و هدف: درمان جاری برای hcv تجویز ترکیبی پگ اینترفرون و ریباورین می باشد. مطالعات اخیر وجود پلی مورفیسم هایی در ناحیه پروموتر ژن il28b را به عنوان فاکتور موثر میزبانی در درمان معرفی نموده است. لذا، هدف از مطالعه حاضر بررسی فراوانی پلی مورفیسم (g/t) مرتبط با rs8099917 در جمعیت ایرانی بوده است. مواد و روش ها: در این مطالعه بررسی مقطعی بر روی 93 نمونه خون بیمار (71 بیمار حساس و 22 بیمار مقاوم...
patients and methods il28b rs8099917 was genotyped in 263 patients with hepatitis c virus (hcv) infection and 244 healthy controls in tianjin, china using taqman snp genotyping method. the roles of rs8099917 and clinical characteristics in antiviral treatment were analyzed by logistic regression. results among 263 patients with chronic hcv infection, 223 had a tt genotype (84.8%). frequencies o...
Interleukin 28B (IL28B) rs12979860 polymorphisms were examined in 41 individuals with human T-lymphotrophic virus type 1 (HTLV-1). The alleles CT/TT were more frequent in 12 individuals with HTLV-1-associated myelopathy/tropical spastic paraparesis than in 29 asymptomatic carriers (80% vs 20%; P = .03), and median HTLV-1 proviral load was greater in CT/TT than CC carriers (P = .01). Thus, IL28B...
Chronic headaches are a common complaint, affecting millions of people worldwide. Underlying causes are varied, and many individuals suffer from multiple types of head pain, including migraines, tension headaches, and temporomandibular joint dysfunction. Many factors can affect pain intensity and frequency including dietary components, physical activity, stress, medications, and emotional event...
