BACKGROUND Although people who inject drugs (PWID) are an important group to receive Hepatitis C Virus (HCV) antiviral therapy, initiation onto treatment remains low. Concerns over reinfection may make clinicians reluctant to treat this group. We examined the risk of HCV reinfection among a cohort of PWID (encompassing all those reporting a history of injecting drug use) from Scotland who achie...
Repeated episodes of acute, symptomatic urinary tract infections in domiciliary patients have been shown to be due to reinfection in 71% of instances and to recrudescence of the original infection in 29%. Fresh episodes occurring at intervals of less than eight weeks from the original infection were due to reinfection or to recrudescence of infection in roughly equal numbers but those at interv...
The resolution of primary and secondary chlamydial genital infection in immunoglobulin A (IgA)-deficient (IgA(-/-)) mice was not different from that in IgA(+/+) mice. Furthermore, depletion of either CD4(+) or CD8(+) T cells prior to reinfection of IgA(+/+) or (-/-) mice had limited impact on immunity to reinfection. Thus, although antibody contributes importantly to immunity to chlamydial geni...
introduction brucella endocarditis, although an uncommon complication of brucellosis, is the main cause of the mortality related to this disease. the best therapy is a combination of antibiotic administration with valve replacement. after treatment of the first episode of endocarditis, new infection may be occurred as a relapse or reinfection. case presentation in this report, we described a pa...
At intervals from 2 to 11 weeks after normal rabbits had inhaled small numbers of virulent bovine tubercle bacilli as separated cells in droplet nuclei, groups of these animals received a single exposure to reinfection during which each animal inhaled about 20,000 separated bacilli. Normal control rabbits which inhaled this large number of bacilli died within 4 weeks thereafter. Their deaths we...
BACKGROUND/AIMS This study investigates the occurrence of HCV reinfection and superinfection among HCV seroconverters participating in the Amsterdam Cohort Studies among drug users from 1985 through 2005. METHODS HCV seroconverters (n=59) were tested for HCV RNA at five different time points: the last visit before seroconversion (t=-1), the first visit after seroconversion (t=1), six months a...
Molecular analysis of recurrent tuberculosis has revealed that a second episode may be caused by a strain of Mycobacterium tuberculosis other than that involved in the first infection, thus indicating that exogenous reinfection plays a role in recurrence. We focused on two aspects of reinfection that have received little attention. First, we evaluated whether a lack of methodological refinement...
BACKGROUND Prosthetic joint infection is an uncommon but serious complication of hip replacement. There are two main surgical treatment options, with the choice largely based on the preference of the surgeon. Evidence is required regarding the comparative effectiveness of one-stage and two-stage revision to prevent reinfection after prosthetic joint infection. METHODS We conducted a systemati...
