Comparison of Serum HBV DNA Levels between Lamivudine Induced HBeAg Seroconversion and Spontaneous Seroconversion
… relapse rate in patients with spontaneous HBeAg seroconversion is usually lower than the rate in patients with lamivudine induced HBeAg seroconversion in Asians with chronic hepatitis B. The aim of this study was to compare serum HBV DNA levels at the time of HBeAg seroconversion between these …

Risk factors associated with HIV seroconversion among pregnant women in Southern province - Zambia
… the possible risks and the prevalence of HIV seroconversion in pregnant women of Southern province in Zambia from 2012 to 2016. Also to assess adherence to the recommended number of HIV tests. It was imperative to undertake this study as the results would provide important insights to policy …

Recent HIV seroconversion at time of first positive test : a comparison before and after HIV reportability
… by the S/LS EIA (detuned test) as a recent seroconversion (RSC) (infected for <170 days) or established infection (>170 days). Data was linked to the BC HIV Surveillance and AIDS databases. The proportion of RSC in the pre-reporting group was compared to the proportion of RSC in the …

Αντισώματα κατά του κυτταρομεγαλοϊού, τοξοπλάσματος Gondii, έρπητα Ι και ΙΙ, ερυθράς και συνδρόμου επίκτητης ανοσολογικής ανεπάρκειας σε πρωτότοκες και πολύτοκες κατά την εγκυμοσύνη
… was done once every pregnancy trimester, so seroconversion was able to be detected. Eighty per cent of 512 women were found seropositive to cytomegalovirus, forty one per cent to toxoplasma gondii, eighty eight per cent to herpes simplex type one and two and eighty four per cent to rubella …

Immune Response in Young Men to the 2014/15 Seasonal Influenza Vaccine
… fat, leptin, sLEPR or CRP were associated with seroconversion rates. Participants with higher physical activity scores had lower seroconversion rates. Differences were found for the A/Texas strain (p<0.01) with a similar trend observed for the other influenza strains. Further work needs to be …

Investigations into the vector competency of arthropods for two Ehrlichias: Ehrlichia risticii and Cowdria ruminantium
… of transmission, either clinically or by seroconversion in mice or ponies was observed. Blackflies (<i>Simulium</i> spp.) were trapped in an area endemic for PHF and inoculated into mice in an attempt to demonstrate <i>I. risticii</i>. No evidence of seroconversion by mice to <i>E. …

A systematic review and meta-analysis of fractional dose compared to standard dose inactivated polio vaccination in children
… that as the number of IPV doses increased the seroconversion rates for fractional dose and full dose IPV approximated each other such that at three doses the rates were similar. In conclusion, there is no difference in seroconversion between three doses of fractional dose IPV and three doses of …

Evaluation of two SARS-CoV-2 immunoassays
… by different SARS-CoV-2 variants. Post-vaccine seroconversion in 115 staff with no evidence of prior natural infection was 99% and hybrid immunity produced higher anti-spike antibody titres compared to vaccine-only participants. Conclusion: Both immunoassays met our acceptance criteria. Both …

The hepatitis B core promoter: Control of viral life cycle events
… replication. Pairedsamples, pre- and post HBeAg seroconversion, were selected from 14 chronic HBVpatients who had a significant decrease in serum viral load after HBeAgseroconversion implying a drop in viral replication. The CP acitivty from each samplewas quantitated via a luciferase reporter …

The intersection of the HIV epidemic and blood donation in South Africa
… as early ART initiation may result in delayed seroconversion, seroreversion, and prolonged suppression of viral replication which may escape detection by HIV antibody and nucleic acid amplification testing (NAT). My PhD research used epidemiologic, incidence modelling and mixed-method …

Defining postmodern masculinities: a symptomatic approach to understanding French masculinities
… to a queer model that necessitates the seroconversion of other queer men. Their texts work in two contradicting fashions: on one hand seroconversion replaces reproduction because in their literary universe only queer HIV+ men can exist and therefore erases heteronormativity from the …

Do condom and needle exchange provision in prisons reduce risky behavior and HIV transmission? A systematic literature review

Resistance to hepatitis C virus : potential genetic and immunological determinants
… immunity, which allows clearance of HCV without seroconversion, and proof-of-principle evidence from in vitro studies that genetic polymorphisms may confer resistance to establishment of infection. This doctoral research project explores evidence for protective immunity, including via genetically …

Analysis of Treatment Effect of Lamivudine, Adefovir Add-on Therapy in Patients with Lamivudine Resistant Chronic B-viral Hepatitis
… and 34.8%/39.1%/52.6% in HBeAg negative group. Seroconversion was observed 10.2%/19.7%/23.6% in 6 months, 1 year, and 2 years. Virologic breakthrough phenomenon was seen 1.1%. Conclusions: LAM and ADV combination therapy effectively suppresses HBV replication and prevents virologic and clinical …

Extent of genotype-specific humoral immunity produced on infection with hepatitis C virus: relevance for serological screening and diagnosis
… affect detection of antibody around the time of seroconversion, as antibody reactivity is likely to be weak and restricted to a limited number of epitopes. The extent of type-specific and type-common components of the humoral immune response were investigated by measuring the antibody levels in …

Behavioural adjuvants to vaccination
… following eccentric exercise. The antibody seroconversion rate to the vaccine was low (approx. 5 %), and thus, further analysis between exercise and control participants was not feasible. In sum, supporting previous research, it appears that acute eccentric exercise can enhance the immune …

Cross-protection and Potential Animal Reservoir of the Hepatitis E Virus
… 2 weeks later. At 4 wks, after confirming seroconversion to IgG anti-HEV antibody with ELISA, all groups except the negative control were challenged with swine genotype 3 HEV (administered intravenously). The protective and cross-protective abilities of these antigens were determined …

Evaluating individuals with extreme phenotypes of HIV-1 contributes towards better healthcare management of all HIV-1 positive individuals
… count < 100 cells/mm3 within one year of HIV-1 seroconversion. Evidence shows that less than 1% of individuals are EC and the majority should start treatment to maximise quality and length of life. We supported the ‘when to start’ evidence by demonstrating a 62% reduced risk of serious Aquired …

HIV and other sexually transmissible infections in a cohort of HIV negative homosexual men in Sydney
… After controlling for sexual behaviour, HIV seroconversion was significantly associated with anal gonorrhoea (HR 12.68, 95% CI 3.66-44.00). The association with anal warts and prevalent HSV-1 infection was of borderline significance. These data will inform intervention designs targeting STIs …
