Rapid detection of cutaneous herpes simplex virus infection with the polymerase chain reaction

A simple and specific method for detecting herpes simplex virus infection in routinely processed paraffin-embedded biopsy specimens is described. DNA is extracted from paraffin blocks, and subjected to DNA amplification with the polymerase chain reaction. After 40 rounds, an amplified band can be detected after agarose gel electrophoresis and ethidium bromide staining. This band is specific for herpes simplex virus, because tissues infected with related viruses do not give this amplified band. We have been able to detect viral DNA in small punch skin biopsies with this procedure, which can take as little as 6 h.     

Cytologic diagnosis of herpes simplex virus infection

Alterations in epithelial cells infected with herpes simplex viruses (HSV) have been described repeatedly^1–7 since Tzank,⁸ in 1947, advocated the use of cytology for the diagnosis of these infections. In spite of successful use of this technique in the following years by Blank and his collaborators,^9,10 enthusiasm for this diagnostic method gradually waned because of the emergence of other, more sophisticated, laboratory tests for viral diagnosis (culture, serology, antibody determination, animal inoculation, electron microscopy, etc.).¹¹For the last 20 years, with the use of the Papanicolaou staining method, cytology has proven to be a fairly reliable, rapid, and simple method of diagnosis of HSV infections. The Pap stain gives better nuclear detail of the alcohol-fixed cells than the original Tzank smear, which was air-dried and Giemsa stained. This cytologic diagnosis has been and continues to be especially significant in detecting cervical herpetic infections through the use of Papanicolaou smears for cancer screening of asymptomatic women.¹²

Psychosocial implications of recurrent genital herpes simplex virus infection.

Fifty seven patients experiencing first attacks of genital herpes simplex virus infection (HSVI) were compared with 50 patients who were concerned about frequently recurring attacks despite routine counselling and reassurance. Using the general health questionnaire this latter group was found to be more psychologically distressed and more socially naive than the first attack group, as measured by socioeconomic class and the lie score of the Eysenck personality questionnaire; otherwise the two groups were similar. Patients presenting to clinics with frequently recurring genital HSVI may therefore be especially psychologically distressed, socially naive, and disadvantaged. Managing these patients needs to include understanding these problems as well as giving advice and using antiviral agents.     

Natural history of genital herpes simplex virus type 1 infection

BACKGROUND: Herpes simplex virus type 1 (HSV-1) has been increasingly reported as a cause of genital herpes, yet there have been few studies on the long-term natural history of this infection.GOAL The goal was to examine the clinical course of genital HSV-1 infection. STUDY DESIGN: This was a cohort study of patients presenting with culture-proven primary genital HSV-1 infection. RESULTS: The median follow-up of the 77 patients was 736 days. The overall rate of recurrences was 1.3/year in the first year of infection, decreasing to 0.7/year in the second year. In the first year of infection, 43% of study patients did not have a recurrence. In the second year of infection, 67% of study patients did not have a recurrence. CONCLUSION: Genital HSV-1 recurs infrequently in most patients, and the rate decreases further in the subsequent years of infection. Because the prognoses of genital HSV-1 and HSV-2 infections differ, determination of the viral type is important for patient counseling.     

Role of type specific herpes simplex virus serology in the diagnosis and management of genital herpes

OBJECTIVES: To investigate the indications for the use of a type specific antibody test for herpes simplex virus in a department of genitourinary medicine in the United Kingdom. METHOD: Retrospective analysis of case records of 127 patients who accepted the test during a 20 month period. RESULTS/CONCLUSION: The test contributed to patient management in 79% of patients with recurrent genital ulceration of unknown cause. It was also useful for counselling a number of patients with initial episodes of disease and the asymptomatic partners of some patients when the partners were shown to possess antibodies specific to herpes simplex virus type 2. When evaluating sexual partners, the test was difficult to interpret if an isolate from the index case had not been typed. Access to viral typing may therefore be a greater priority than serological testing. As adverse psychological sequelae may follow the identification of an asymptomatic chronic infection, guidelines for the use of a type specific serological test are proposed.

Acquisition of concomitant oral and genital infection with herpes simplex virus type 2

Primary oral and genital infections caused by herpes simplex virus type 2 were diagnosed in an 18-year-old female. A history of sexual practices was critical in determining the anatomic sites of infection. Restriction endonuclease analysis of viral DNAs helped to identify the male sexual partner from whom the virus had been acquired. He had been infected recently by a previous sexual partner but had not yet developed lesions. Clinicians should obtain a history of sexual practices from patients with newly acquired genital herpes and should advise patients with genital herpes that transmission of virus to sexual partners can occur in the absence of overt lesions.     

One-day regimen of valacyclovir for treatment of recurrent genital herpes simplex virus 2 infection

OBJECTIVES: To evaluate the efficacy of a 1-day course of valacyclovir in reducing the duration and severity of genital herpes recurrences and to measure the frequency of viral shedding episodes subsequent to antiviral therapy. STUDY DESIGN: In an open-label pilot study, patients with recurrent genital herpes simplex virus 2 (HSV-2) infection were given a 1-day course of valacyclovir (2000 mg given by mouth twice daily) to be taken at the first sign of recurrence or prodrome. Participants maintained diaries of signs and symptoms and collected genital swabs for viral culture while lesions persisted and HSV DNA PCR for 14 days after initiating treatment. RESULTS: Ninety (78%; 41 men, 49 women) of the 115 enrolled persons experienced either a lesional recurrence or prodrome. Seventy-seven (86%) participants developed lesions; 4 (5%) participants experienced a second lesional recurrence during the 14-day study period. The median lesion duration was 5 days, episode duration was 5 days, and pain duration was 3 days. Viral shedding was detected in 60 persons by PCR and 31 persons by culture. Shedding detected by culture lasted for a median of 2 days, and shedding detected by PCR lasted for a median of 3 days. Of 60 participants with viral shedding, 14 (23%) had an additional shedding episode after their initial lesion healed, lasting for a median of 2 days. CONCLUSIONS: A 1-day course of valacyclovir may be a convenient treatment for recurrent genital herpes and comparative trials are warranted.

Duplex real-time polymerase chain reaction assay for detection and quantification of herpes simplex virus type 1 and herpes simplex virus type 2 in genital and cutaneous lesions

BACKGROUND: A sensitive and specific method for detecting herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) is important for diagnosing genital and cutaneous infections. GOAL: The goal of this study was to compare quantitative real-time polymerase chain reaction (qPCR) with virus culture for diagnosis of genital and cutaneous HSV-1 and HSV-2. STUDY DESIGN: A duplex qPCR system for quantification of DNA from HSV-1 and HSV-2 was developed. Duplicate swabs for PCR and virus culture were collected from 89 patients attending our sexually transmitted infection and dermatology clinic. RESULTS: The duplex qPCR had a linear measure interval of 10-10 copies/mL. The detection limit was between 1 and 5 copies per reaction. qPCR detected HSV in 57 (64%) specimens and virus was isolated in 45 (50%) cases. First-episode infections showed higher viral quantities with a median value of 4.2 x 10 copies per reaction compared with recurrent infections with 1.0 x 10 (P = 0.0002). HSV-1 was more likely to be the cause of first-episode genital infections (72%), and HSV-2 of recurrent and atypical genital manifestations (73%). CONCLUSION: Real-time PCR is a sensitive method for diagnosing genital herpes, and the duplex format is convenient for typing. The method increased the detection rate by 27% compared with virus culture.     

Anaerobic bacteria and herpes simplex virus in genital ulceration.

Of 91 patients with genital ulceration, herpes simplex virus was isolated from 52 (57%) and Haemophilus ducreyi from 12 (13%); none had syphilis. The difference in incidence of other aerobes in patients and controls was not significant. Anaerobes, predominantly Bacteroides spp, were isolated from a large proportion (77%) of men and women patients with ulcers but from few control men. The most common anaerobic species were B asaccharolyticus and B ureolyticus, with fewer isolates of the melaninogenicus/oralis group. The bacterial flora of herpetic and non-herpetic ulcers were similar, but Candida albicans was isolated significantly more often from non-herpetic ulcers. Anaerobic bacteria may contribute to the pathogenesis of genital ulcers.     

The frequency of unrecognized type 2 herpes simplex virus infection among women. Implications for the control of genital herpes

To evaluate the prevalence of symptomatic versus asymptomatic or unrecognized type 2 herpes simplex virus (HSV-2) infection, the authors performed physical examination, viral cultures, and type-specific serologic assays in 776 randomly selected women attending an STD clinic and 636 female university students. Forty-six percent of women attending the STD clinic compared with 8.8% of the university students had serologic evidence of HSV-2 infection. Clinical or historical evidence of genital herpes was present in only 34% of the HSV-2 seropositive women attending the STD clinic and in 29% of the HSV-2 seropositive women attending the university clinic. Among women attending the STD clinic, the prevalence of recognized genital infection was more common among those with HSV-2 antibodies only versus those with HSV-1 and -2 antibodies (odds ratio = 2.39; 95% confidence interval = 1.30-4.37), suggesting that HSV-1 infection reduces the likelihood of recognizing HSV-2 infection. In view of the high proportion of seropositive individuals with unrecognized HSV-2 infection in both high and low prevalence HSV-2 seropositive populations, newly developed HSV type-specific serologic methods should be evaluated for detecting carriers of HSV-2 infection and counseling these individuals about strategies for avoiding sexual and perinatal transmission of HSV-2.     

Increasing proportion of herpes simplex virus type 1 as a cause of genital herpes infection in college students

A retrospective review of genital herpes simplex virus (HSV) isolates collected in a university student health service over a 9-year period showed that an increasing proportion of isolates were HSV-1 rather than HSV-2. HSV-1 accounted for 78% of all genital isolates in this population by 2001, compared with 31% of isolates in 1993. BACKGROUND: Herpes simplex virus (HSV) type 1 is usually thought to cause less than 30% of genital herpes infections in the United States, but the proportion of infections resulting from HSV-1 is increasing in some populations. GOAL: The goal was to review the relative proportion of HSV-1 and HSV-2 as the cause of newly diagnosed genital herpes infections in a population of U.S. college students and to assess trends in the change of this proportion over time. STUDY DESIGN: Genital HSV isolates collected at a university student health service from 1993 to 2001 (n = 499) were reviewed retrospectively. Analyses included comparisons of isolates by HSV type, age group, and sex. RESULTS: The proportion of newly diagnosed genital herpes infections resulting from HSV-1 increased from 31% in 1993 to 78% in 2001 (P <0.001, linear trend P <0.001). HSV-1 was more common in females than males, but increases were noted for both sexes. HSV-1 was more common in persons aged 16 to 21 than in persons aged 22 or older. CONCLUSIONS: HSV-1 has become the most common cause of newly diagnosed genital herpes infections in this population of college students and reflects a reversal of the usual HSV-1/HSV-2 ratio.
