High level of vaccination and protection against hepatitis B with low rate of HCV infection markers among hospital health care personnel in north of Iran: a cross-sectional study.

Background: hepatitis B virus (HBV) and C virus (HCV) are among the leading causes of mortality worldwide. Health care personnel (HCP) are subjected to increased risk of these infections. Therefore, HBV vaccination and post-vaccination serologic testing (PVST) are recommended for them.

Long-term Protection Against the Hepatitis B Virus Detected Through an Early Response to a Booster Dose Injection.

Objective: To determine the duration of protection conferred by the hepatitis B (HB) vaccination and the necessity of a booster dose.

Methods: Immediately after the initial blood sampling, 252 youths (aged 18.8-20.

Nosocomial Infections: Multicenter surveillance of antimicrobial resistance profile of Staphylococcus aureus and Gram negative rods isolated from blood and other sterile body fluids in Iran.

Background And Objective: Antibiotic resistance is increasing, especially in healthcare-associated infections causing significant public health concerns worldwide. National information is required to make appropriate policies, update list of essential drugs for treatment, and evaluate the effects of intervention strategies. A nationwide surveillance of antimicrobial resistant bacteria in nosocomial infections was established in Iran in 2008, so that the data obtained through the surveillance would enable us to construct a database.

Long-term T-cell-mediated immunologic memory to hepatitis B vaccine in young adults following neonatal vaccination.

Background: The long-term duration of cell-mediated immunity induced by neonatal hepatitis B virus (HBV) vaccination is unknown.

Objectives: Study was designed to determine the cellular immunity memory status among young adults twenty years after infantile HB immunization.

Patients And Methods: Study subjects were party selected from a recent seroepidemiologic study in young adults, who had been vaccinated against HBV twenty years earlier.

Prevalence of hepatitis B virus seromarkers in young adults vaccinated at birth; impact on the epidemiology of hepatitis B infection in iran.

Background: The epidemiological impact and the duration of protection provided by infant hepatitis B (HB) vaccination are unknown.

Objectives: This study was designed to determine the hepatitis B virus (HBV) infection seromarkers in young adults who have been vaccinated against HBV as the first group of Iranian neonates during 1993 and 1994.

Patients And Methods: We recruited 510 young adults with a history of complete HB vaccination at birth.

Increasing antibiotic resistance among uropathogens isolated during years 2006-2009: impact on the empirical management.

Unlabelled: Urinary tract infections (UTI) are one of the most common infections with an increasing resistance to antimicrobial agents.

Purpose: Empirical initial antibiotic treatment of UTI must rely on susceptible data from local studies.

Materials And Methods: Retrospective analysis of isolated bacteria from children with UTIs was performed at the university hospital during years 2006-2009.

Bordetella pertussis IgG and IgA antibodies seroprevalence among 1-35 y-old population: the role of subclinical pertussis infection.

Objective: To determine age-dependent pertussis specific IgG and IgA antibodies seroprevalence in apparently healthy subjects.

Methods: A total of 595 healthy 1-35-y-old individuals divided into 5 different age groups were selected from Sari district. Antipertussis IgG and IgA antibodies levels were measured quantitatively by ELISA method.

Measles-mumps-rubella revaccination; 18 months vs. 4-6 years of age: potential impacts of schedule changes.

Objective: The policy of administering the second dose of measles-mumps-rubella (MMR) vaccine (MMR(2)) has recently changed in Iran, at age 1.5 years instead of 4-6 years previously. The effects of such a change on the immune status of the individual are evaluated in this study.

Seroimmunity to diphtheria and tetanus among mother-infant pairs; the role of maternal immunity on infant immune response to diphtheria-tetanus vaccination.

Background: This study was designed to determine the levels of immunity against diphtheria and tetanus in 110 mothers with/without diphtheria-tetanus toxoid (dT) vaccination during pregnancy and their two-month-old infants before diphtheria-tetanus-pertussis (DTP) immunisation, and also to assess the influence of pre-vaccination passive immunity on the infants' immune response to three doses of DTP vaccination.

Subjects And Methods: Sera from 110 mother-infant pairs before DTP vaccination and from 69 infants after receipt of three doses of DTP vaccine were tested to measure antidiphtheria-antitetanus toxin IgG levels, using a commercial enzyme immunoassay. History of dT toxoid vaccination of mothers at pregnancy was recorded.
