چکیده

A recently developed method to recover proteins from cervical secretions was combined with methods to detect minute concentrations of herpes simplex virus (HSV) type specific antibodies to measure the concentrations of locally produced antibodies in women with genital infections. Forty nine women attending a sexually transmitted disease (STD) clinic were included. Cervical secretions were obtained by suction into a plastic catheter. Soluble proteins were recovered from the secretions by elution with hyperosmolar sodium chloride. A rabbit antibody to human secretory component, which was conjugated to horseradish peroxidase, was used to measure secretory IgA (S-IgA) that was HSV type specific. For comparison, HSV type specific IgG was measured in serum samples from the patients. Of the 49 women, 16 yielded detectable HSV type 2 (HSV 2) S-IgA in secretions. Twelve of them also reacted to the HSV type common antigen, but only five had HSV 2 IgG detectable in their serum. S-IgA against HSV was found in significantly more women with a clinical diagnosis of acute cervicitis than in others. This could be explained by a general increase in local antibody production and immunity triggered by previous contacts with HSV. It is concluded that local mucosal immunity to HSV 2 can be detected in women who do not have a specific humoral antibody response to the virus. For seroepidemiological studies of infection with HSV 2 this local immunity may be considered to be a factor that gives an underestimation of the true incidence of HSV 2 infection.

Immunoglobulin G is the main protective antibody in mouse vaginal secretions after vaginal immunization with attenuated herpes simplex virus type 2.

We investigated the protective role of antibodies in vaginal secretions of mice that were immune to vaginal challenge with herpes simplex virus type 2 (HSV-2). Unfractionated vaginal immunoglobulins from immune and nonimmune mice and affinity-purified immunoglobulin G (IgG) and secretory IgA (S-IgA) from immune secretions were adjusted to their concentrations in vivo. Wild-type HSV-2 was incuba...

Cervical Antibodies to Herpes Simplex Virus Proteins in Pregnancy and Puerperium: A Pilot Study

OBJECTIVE This study was undertaken to evaluate the changes in total and anti-herpes simplex virus (HSV)-specific cervical IgA and IgG antibody profiles during and after pregnancy. METHODS Serum and cervical secretions were obtained from pregnant patients before 20 weeks gestation, at 34-36 weeks gestation, and at 6 weeks postpartum and tested for total IgA and IgG antibody and for IgA and Ig...

Secretory IgA specific for herpes simplex virus in lacrimal fluid from patients with herpes keratitis--a possible diagnostic parameter.

In the present study a solid-phase radioimmune assay was used for the demonstration of herpes simplex virus-specific IgG and secretory IgA antibodies in the lacrimal fluid from patients with active recurrent herpes keratitis. The method was quantitative and made it possible to test specifically for the production of secretory IgA antibodies produced during an active herpes simplex virus infecti...

Secretory immunoglobulin a and herpes keratitis.

The sensitization of herpes simplex virus by immunoglobulin G (IgG) antibodies was studied. Although herpes simplex virus sensitized by IgG could not be neutralized by IgA antibodies known to neutralize a similar number of unsensitized viruses, this protection could be overcome by larger amounts of IgA antibodies. This suggests that the effective neutralization of herpes simplex virus in ocular...

Indirect micro-immunofluorescence test for detecting type-specific antibodies to herpes simplex virus.

A rapid indirect micro-immunofluorescence test capable of detecting and differentiating type-specific antibodies to herpes simplex virus is described. The test proved highly sensitive and, in 80 patients with active herpes ocular infection, antibody was detected in 94%. No anti-herpes antibody was detected in a control group of 20 patients with adenovirus infections. Testing of animal sera prep...
