AIM To investigate the association between interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) polymorphisms and interferon-α (IFNα) treatment efficiency among Chinese hepatitis B virus (HBV) infection patients. METHODS Two hundred and twenty five newly diagnosed chronic hepatitis B (CHB) patients were enrolled in the study. All of these patients received IFNα treatment for a ...
background hepatitis b virus (hbv) is one of the most common chronic viral infections in the world. iran has a low to intermediate hbv prevalence and approximately 1.5 million people are living with hbv infection. the impact of hbv in iran is unknown and given the very low levels of alcohol consumption, this region provides an opportunity to examine the impact of isolated chronic hbv infection....
OBJECTIVE To determine whether there has been a tendency for early post-seroconversion CD4 cell counts to change over calendar time. DESIGN A prospective cohort study of individuals with well-estimated dates of seroconversion. METHODS We studied 1251 individuals who seroconverted to HIV in Italy between 1985 and 2002, and for whom the first CD4 count was measured within 2 years of seroconve...
BACKGROUND Hepatitis B e antigen (HBeAg) seroconversion is an important hallmark in the natural course of chronic hepatitis B. This study was designed to predict early HBeAg seroconversion within 1 year, by not only biochemical and virological markers, but also pathological parameters in patients with chronic hepatitis B. MATERIAL/METHODS In a retrospective cohort study, 234 patients with HBe...
introduction: influenza can cause more severe diseases and higher rate of morbidity and mortality in the elderly population. therefore, they should receive influenza vaccine annually. however, the host response to vaccine is less in older individuals. on the other hand, selenium can act as a stimulator of the immune system and cause increased immunity and response to vaccine. this study was car...
BACKGROUND It is well established that the prevalence of human papillomavirus (HPV) infection is increased among human immunodeficiency virus (HIV)-positive individuals, but the temporal relationships between these infections are unclear. METHODS During a South African cervical cancer screening trial, 5595 women 35-65 years of age were followed up for 36 months; 577 women were HIV positive at...
In the absence of a cytomegalovirus (CMV) vaccine, other strategies for prevention of primary infection in pregnancy should be considered. Behavioural interventions have been reported to significantly decrease seroconversion rate among seronegative pregnant women. We report here on a recently completed controlled study in which seronegative women at high risk of infection because of close conta...
