Comparison of Passive Haemagglutination and Neutralization Tests to Demonstrate Genital Herpes Virus (HSV2) Antibodies in Pregnant Women

چکیده مقاله:
Background and Aims: Herpes simplex virus (HSV) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. Herpes simplex virus type 2 (HSV2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. Generalized infections in newborns are also predominantly HSV2. Therefore, due to the increasing HSV2 infections especially subclinical in women, the need to diagnose herpes simplex virus infections has increased. Materials and Methods: In the present study, the passive haemagglutination (PHA) test was applied to determine the titer of Anti-HSV2 antibodies. Sheep red blood cells (SRBCs) were treated with tannic acid at concentration of 0.002% and sensitized with HSV2 that had been propagated in HeLa cells. The tannic acid treated and HSV2 sensitized SRBCs were added to U-shaped 96 wells microtiter plates which contained serial dilutions of patient’s sera. Furthermore, serum neutralization test (SNT) was applied as a gold standard to determine the specificity and sensitivity of PHA test. Results: The results of PHA were examined after one hour incubation at 37°C. The endpoint was the highest dilution of serum which gave positive agglutination and compaired with serum neutralization test (SNT as a gold standard to determine the specificity and sensitivity of PHA test. Peripheral blood samples were obtained from 100 pregnant women and evaluated by both SNT and PHA tests. The specificity and sensitivity of PHA test were 92.68%, and 100% respectively. The results indicated that PHA test was easy, rapid and inexpensive but also had acceptable sensitively and specificity. Conclusion: PHA test can be used to determine the level of Anti-HSV2 antibodies and the rate of infection in pregnant women which could be an indication of infection and the risk of transmitting herpes to the newborn.

Because of the technical problems and length of time involved in the satisfactory performance of the haemagglutination-inhibition test for detection of rubella-specific antibodies, a commercially available passive haemagglutination (PHA) kit utilising rubella antigen-sensitised human erythrocytes was tested for its suitability for use in diagnostic laboratories. The immune response to acute rub...

Introduction: Herpes Simplex Virus type 2 (HSV-2) is a highly prevalent sexually transmitted infection (STI) The prevalence of HSV-2 infection is increasing in many populations and geographic areas . Herpes simplex virus type 2 (HSV-2) is the cause of most genital herpes and is almost always sexually transmitted. Most HSV-2 infections are consequently expected to occur after the onset of sexua...

Antiphospholipid antibodies (APLA) may be detected in normal pregnancies and also may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. In the present study the possible differences in APLA titer between healthy pregnant women and preeclampsia cases without history of thrombosis was examined. The APLA titer in 50 healthy pregnant women with 50 preeclampsia cases wit...
