Effect of serologic status and cesarean delivery on transmission rates of herpes simplex virus from mother to infant 总被引:19,自引:0,他引:19
CONTEXT: Neonatal herpes most commonly results from fetal exposure to infected maternal genital secretions at the time of delivery. The risk of transmission from mother to infant as it relates to maternal herpes simplex virus (HSV) serologic status and exposure to HSV in the maternal genital tract at the time of labor has not been quantified. Furthermore, no data exist on whether cesarean delivery, the standard of care for women with genital herpes lesions at the time of delivery, reduces HSV transmission. OBJECTIVE: To determine the effects of viral shedding, maternal HSV serologic status, and delivery route on the risk of transmission of HSV from mother to infant. DESIGN: Prospective cohort of pregnant women enrolled between January 1982 and December 1999. SETTINGS: A university medical center, a US Army medical center, and 5 community hospitals in Washington State. PATIENTS: A total of 58 362 pregnant women, of whom 40 023 had HSV cultures obtained from the cervix and external genitalia and 31 663 had serum samples tested for HSV. MAIN OUTCOME MEASURE: Rates of neonatal HSV infection. RESULTS: Among the 202 women from whom HSV was isolated at the time of labor, 10 (5%) had neonates with HSV infection (odds ratio [OR], 346; 95% confidence interval [CI], 125-956 for neonatal herpes when HSV was isolated vs not isolated). Cesarean delivery significantly reduced the HSV transmission rate among women from whom HSV was isolated (1 [1.2%] of 85 cesarean vs 9 [7.7%] of 117 vaginal; OR, 0.14; 95% CI, 0.02-1.08; P =.047). Other risk factors for neonatal HSV included first-episode infection (OR, 33.1; 95% CI, 6.5-168), HSV isolation from the cervix (OR, 32.6; 95% CI, 4.1-260), HSV-1 vs HSV-2 isolation at the time of labor (OR, 16.5; 95% CI, 4.1-65), invasive monitoring (OR, 6.8; 95% CI, 1.4-32), delivery before 38 weeks (OR, 4.4; 95% CI, 1.2-16), and maternal age less than 21 years (OR, 4.1; 95% CI, 1.1-15). Neonatal HSV infection rates per 100 000 live births were 54 (95% CI, 19.8-118) among HSV-seronegative women, 26 (95% CI, 9.3-56) among women who were HSV-1-seropositive only, and 22 (95% CI, 4.4-64) among all HSV-2-seropositive women. CONCLUSION: Neonatal HSV infection rates can be reduced by preventing maternal acquisition of genital HSV-1 and HSV-2 infection near term. It can also be reduced by cesarean delivery and limiting the use of invasive monitors among women shedding HSV at the time of labor. 相似文献

Genital herpes and public health: addressing a global problem 总被引:26,自引:0,他引:26
Genital herpes can be caused by herpes simplex virus 2 (HSV-2) or, less commonly, by herpes simplex virus 1 (HSV-1). With a seroprevalence of antibodies to HSV-2 of 22% in the general population, genital herpes is 1 of the 3 most prevalent sexually transmitted diseases (STDs) in the United States. A central issue in the public health problem of genital herpes is the high proportion of genital HSV infections that are unrecognized by both patients and clinicians. Persons who are HSV-2 seropositive may be symptomatic but nevertheless fail to recognize genital herpes; they serve as reservoirs for transmission. Physicians and patients must be aware of the subclinical presentation of genital herpes and the potential these patients have for transmitting HSV. Serious consequences of HSV infection include neonatal herpes and increased risk of human immunodeficiency virus transmission. Recommendations to physicians for prevention include using type-specific tests for HSV when screening for other STDs and testing for HSV when evaluating patients with genital ulcers. Researchers must evaluate the performance of type-specific tests and strategies to prevent transmission. 相似文献

A case of neonatal herpes that occurred after vaginal delivery in the absence of genital lesions is presented. The mother had a history of drug addiction and genital herpes. Asymptomatic shedding of herpes simplex virus type 2 from the cervix was noted in the second trimester of pregnancy. Despite being followed with a protocol of close surveillance and serial culturing of the genital tract, the patient gave birth to twins, one of whom developed herpes simplex virus type 2 in the postpartum period. This report presents discussion of this case and herpes surveillance protocols. 相似文献

Transmission of genital herpes by donor insemination 总被引:7,自引:0,他引:7
This report describes a donor in a therapeutic donor insemination program who asymptomatically acquired a primary herpes simplex virus type 2 (HSV-2) infection from his long-standing sexual partner. His fresh semen was used to inseminate two HSV-seronegative recipients; in one a primary HSV-2 infection developed, and in one it did not. Direct evidence of transmission from donor to recipient was documented by restriction enzyme analysis of the HSV-2 isolates obtained from the donor's semen and from the recipient's cervix. Because of the possibility of asymptomatic acquisition and transmission of HSV-2, semen donors and their sexual partners should undergo serologic screening for genital herpes using new, type-specific HSV serologic techniques. 相似文献

The association between genital ulcer disease and acquisition of HIV infection in homosexual men 总被引:24,自引:0,他引:24
We analyzed the association of herpes simplex virus (HSV) infection and syphilis, the two most common causes of genital ulceration in homosexual men, with human immunodeficiency virus (HIV) infection in 200 men enrolled between 1983 and 1986 into a study evaluating the microbial causes of acute proctitis. Infection with HIV was independently associated with a history of syphilis, serologic evidence of syphilis, a history of HSV infection, and antibody to HSV-2. Antibody to HIV was not associated with a history of other genital infections or with antibody to Chlamydia trachomatis or HSV-1. Similar associations were observed in 111 asymptomatic homosexuals seen for HIV screening. Men who presented with primary HSV proctitis had a lower prevalence of HIV antibody than those with preexisting HSV-2 antibody (44% vs 68%); this suggests that HSV-2 infection antedated HIV infection. These data suggest that genital ulcerative diseases are an important risk factor for the acquisition of HIV infection in homosexual men; measures directed at control of these diseases may reduce the transmission of HIV in this population. 相似文献

INTRODUCTION: This study was performed to compare nested-polymerase chain reaction (PCR) with viral culture as a diagnostic tool for genital herpes simplex virus (HSV) infection in a sexually transmitted infection (STI) clinic in Singapore. METHODS: 103 consecutive patients presenting with clinical features suggestive of genital herpes were enrolled in the study. Two swabs were obtained from each patient. On one swab, cell culture and typing was performed, and on the second swab, nested-PCR was performed and the infecting viral type was determined by using type-specific primers. RESULTS: 63 patients (61.2 percent) had a positive PCR test for HSV. Of these, 13 patients (20.6 percent) had HSV type 1 (HSV-1), 50 patients (79.4 percent) had HSV type 2 (HSV-2). HSV-1 and HSV-2 were detected by viral culture in only six patients and 24 patients, respectively. The sensitivity of cell culture compared to PCR was 46.1 percent for HSV-1 infection and 48 percent for HSV-2 infection. PCR further detected an additional 52.4 percent of HSV cases. The specificity of PCR was 100 percent. CONCLUSION: Nested-PCR has been shown in this study to be an effective diagnostic and typing method for HSV infection in a STI clinic in Singapore with its higher sensitivity and specificity to routine viral isolation in cell culture. 相似文献

The shedding of herpes simplex virus type-1 (HSV-1) into the saliva was compared in 28 patients with oral cancer and 26 patients with genital or urological cancer. All subjects tested positive for HSV-1 specific antibody. A statistically significant (p less than 0.001) difference was found: infectious viruses were isolated from 12 (39.8%) of the oral cancer patients versus only 2 (7.6%) of the genital or urological patients. This indicates that direct stimulation of peripheral nerves during surgery was responsible for the greater reactivation of HSV-1. 相似文献

OBJECTIVE. To examine the extent and correlates of infection with herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in an inner-city community, we studied the prevalence of antibodies to these viruses and their association with risk behaviors in a representative sample of unmarried white, black, and Hispanic adults living in San Francisco, Calif. DESIGN. Cross-sectional, community-based, random household survey. PARTICIPANTS. In 1988 and 1989, we surveyed 1770 unmarried men and women aged 20 to 44 years from three San Francisco neighborhoods of varying geographic and cultural characteristics. MAIN OUTCOME MEASURES. HSV-1 and HSV-2 antibodies based on an immunodot assay using type-specific glycoproteins gG-1 and gG-2. RESULTS. Of blood samples from 1212 participants available for testing, 750 (62%) had HSV-1 antibodies and 400 (33%) had HSV-2 antibodies. After controlling for other variables, HSV-1 antibody was significantly correlated (P less than .05) with older age (in heterosexual men, women, and homosexually active men), less education (in heterosexual men and women), and Hispanic (especially those not born in the United States) or black race. HSV-2 antibody was significantly correlated (P less than .05) with female gender, number of lifetime sexual partners and older age (in heterosexual men and women), and low levels of education and black or Hispanic race (in women). Among those with antibody to HSV-2, only 28 (19%) of 149 men and 32 (13%) of 251 women reported a history of genital herpes. However, most men (62%) and women (84%) who reported a history of genital herpes had HSV-2 antibodies. We observed a similar pattern (low sensitivity and moderate specificity) for a history of facial herpes and the presence of HSV-1 antibodies. After controlling for other variables, HSV-2 antibodies were associated with a lower frequency of HSV-1 antibodies among homosexual men infected with the human immunodeficiency virus. CONCLUSIONS. HSV-1 antibodies were found in nearly two thirds of single urban adults and were most common among Hispanics not born in the United States. HSV-2 antibodies were found in one third of this population and were associated with risk behaviors for sexually transmitted diseases. For both facial and genital herpes infections, self-reporting of infection was very insensitive and moderately specific. 相似文献
