    In recent years, a great increase in interest in genital herpes has been stimulated partly by the rising prevalence of this disease and partly by observations suggesting that genital herpes is a cause of cervical cancer. The clinical pictures produced by genital herpes simplex virus infections are similar in men and women. In contrast to recurrent attacks, initial episodes of infection are generally more extensive, last longer, and are more often associated with regional lymphadenopathy and systemic symptoms. Genital herpes in pregnancy may pose a serious threat to the newborn infant. Although the data suggesting genital herpes simplex virus infection is a cause of cervical cancer are quite extensive, the evidence is largely circumstantial. In spite of these more serious aspects of genital herpes simplex virus infection, episodes of genital herpes are almost always self-limited and benign. Frequent recurrences pose the major therapeutic and management problem. At present, there is no satisfactory treatment for recurrent genital herpes simplex virus in fection. Many of the suggested therapies, although some sound very promising, are potentially dangerous and should be used only under carefully controlled conditions.

    2015-01-01

    SUMMARY Herpes simplex virus 2 (HSV-2) is a DNA virus that is efficiently transmitted through intimate genital tract contact and causes persistent infection that cannot be eliminated. HSV-2 may cause frequent, symptomatic self-limited genital ulcers, but in most persons infection is subclinical. However, recent studies have demonstrated that the virus is frequently shed from genital surfaces even in the absence of signs or symptoms of clinical disease and that the virus can be transmitted during these periods of shedding. Furthermore, HSV-2 shedding is detected throughout the genital tract and may be associated with genital tract inflammation, which likely contributes to increased risk of HIV acquisition. This review focuses on HSV diagnostics, as well as what we have learned about the importance of frequent genital HSV shedding for (i) HSV transmission and (ii) genital tract inflammation, as well as (iii) the impact of HSV-2 infection on HIV acquisition and transmission. We conclude with discussion of future areas of research to push the field forward. PMID:26561565

    Clinical and subclinical genital herpes simplex virus type 2 (HSV-2) reactivations have been associated with increases in human immunodeficiency virus (HIV)-1 genital shedding. Whether HSV-2 shedding contributes to the selection of specific genital HIV-1 variants remains unknown. We evaluated the genetic diversity of genital and blood HIV-1 RNA and DNA in 14 HIV-1/HSV-2-co-infected women, including seven with HSV-2 genital reactivation, and seven without as controls. HIV-1 DNA and HIV-1 RNA env V1-V3 sequences in paired blood and genital samples were compared. The HSV-2 selection pressure on HIV was estimated according to the number of synonymous substitutions (dS), the number of non-synonymous substitutions (dN) and the dS/dN ratio within HIV quasi-species. HIV-1 RNA levels in cervicovaginal secretions were higher in women with HSV-2 replication than in controls (p0.02). Plasma HIV-1 RNA and genital HIV-1 RNA and DNA were genetically compartmentalized. No differences in dS, dN and the dS/dN ratio were observed between the study groups for either genital HIV-1 RNA or plasma HIV-1 RNA. In contrast, dS and dN in genital HIV-1 DNA were significantly higher in patients with HSV-2 genital reactivation (p genital HIV-1 DNA was slightly higher in patients with HSV-2 genital replication, indicating a trend for purifying selection (p 0.056). HSV-2 increased the genetic diversity of genital HIV-1 DNA. These observations confirm molecular interactions between HSV-2 and HIV-1 at the genital tract level.

    Whether unique human immunodeficiency type 1 (HIV) genotypes occur in the genital tract is important for vaccine development and management of drug resistant viruses. Multiple cross-sectional studies suggest HIV is compartmentalized within the female genital tract. We hypothesize that bursts of HIV replication and/or proliferation of infected cells captured in cross-sectional analyses drive compartmentalization but over time genital-specific viral lineages do not form; rather viruses mix between genital tract and blood. Eight women with ongoing HIV replication were studied during a period of 1.5 to 4.5 years. Multiple viral sequences were derived by single-genome amplification of the HIV C2-V5 region of env from genital secretions and blood plasma. Maximum likelihood phylogenies were evaluated for compartmentalization using 4 statistical tests. In cross-sectional analyses compartmentalization of genital from blood viruses was detected in three of eight women by all tests; this was associated with tissue specific clades containing multiple monotypic sequences. In longitudinal analysis, the tissues-specific clades did not persist to form viral lineages. Rather, across women, HIV lineages were comprised of both genital tract and blood sequences. The observation of genital-specific HIV clades only in cross-sectional analysis and an absence of genital-specific lineages in longitudinal analyses suggest a dynamic interchange of HIV variants between the female genital tract and blood.

    Genital herpes is a sexually transmitted disease caused by the herpes simplex virus. Following the initial infection the virus becomes latent in the sacral ganglia. Approximately 80% of patients are then subject to milder but unpredictable recurrences and may shed the virus even when they are asymptomatic. The disorder causes concern because genital herpes in the mother can result in rare but catastrophic neonatal infection and because of a possible association between genital herpes and cancer of the cervix. No effective treatment is as yet available. Weekly monitoring for virus by cervical culture from 32 weeks' gestation is recommended for women with a history of genital herpes and for those whose sexual partner has such a history.

    A nucleic acid vaccine, expressing the gene encoding herpes simplex virus (HSV) type 2 glycoprotein D (gD2) under control of the cytomegalovirus immediate-early gene promoter, was used to immunize guinea pigs against genital HSV-2 infection. The vaccine elicited humoral immune responses comparable to those seen after HSV-2 infection. Immunized animals exhibited protection from primary genital HSV-2 disease with little or no development of vesicular skin lesions and significantly reduced HSV-2 replication in the genital tract. After recovery from primary infection, immunized guinea pigs experienced significantly fewer recurrences and had significantly less HSV-2 genomic DNA detected in the sacral dorsal root ganglia compared with control animals. Thus, immunization reduced the burden of latent infection resulting from intravaginal HSV-2 challenge, and a nucleic acid vaccine expressing the HSV-2 gD2 antigen protected guinea pigs against genital herpes, limiting primary infection and reducing the magnitude of latent infection and the frequency of recurrent disease.

    Primary herpes simplex virus (HSV) infections of female genital tract usually end with remission, while the virus remains in the organism--almost in the sacral ganglion in a latent form, protected from humoral and cellular immunity. Stress induces the virus and the result is recurrent genital infection. Frequent exacerbations damage some parts of vital cellular structures without cytolysis, but stimulate malignant transformations. Vulvar (portio vaginalis uteri) and endometrial tumor tissue samples were analyzed for HSV by direct and indirect fluorescent antibody technique (FAT). Pre and postoperative sera samples were analyzed for presence of anti-HSV antibodies--IgM and IgG by Elisa-Enzygnost method. Acellular filtrates obtained by ultrasonic destruction of malignant tissues were used as inoculum for rabbit corneal scarification. Out of 63 tissue samples, 42 were positive for HSV antigen i.e. 67.3%. According to location 50% of vulvar, 76% PVU and 65% of endometrial tissues were positive. This antigen induces production of virus specific antibodies. Two types of antigens are known: the so-called T-antigen persisting in the cell nucleus and cell-surface antigen--product of the viral genome and can be evidenced by immunofluorescence method. Anti HSV antibodies were present in 63 preoperative serum samples and belonged to IgG group, but not one to IgM, implying a long and chronic course of infection excluding acute primary. Out of 38 postoperative serums the titer of antibodies decreased in 36 evidently, but in two samples remained unchanged. Two samples of endometrial and one from PVU origin contained HSV antigen type one. In the remaining 16 samples HSV 2 antigen was present. Rabbit corneal scarification was the proof of complete infectious virus in malignant tissues. Acellular filtrate of malignant tissues served as inoculum. Corneas of examined rabbits showed a mild inflammation after 24 hours which disappeared in the next 24 hours. We could not isolate the

    To estimate the frequency of isolation of herpes simplex virus (HSV) from the genital tract when recurrent herpes lesions were present on the buttocks. Data were extracted from a prospectively observed cohort attending a research clinic for genital herpes infections between 1975 and 2001. All patients with a documented herpes lesion on the buttocks, upper thigh or gluteal cleft ("buttock recurrence") and concomitant viral cultures from genital sites including the perianal region were eligible. We reviewed records of 237 subjects, 151 women and 86 men, with a total of 572 buttock recurrences. Of the 1,592 days with genital culture information during a buttock recurrence, participants had concurrent genital lesions on 311 (20%, 95% confidence interval [CI] 14-27%) of these days. Overall, HSV was isolated from the genital region on 12% (95% CI 8-17%) of days during a buttock recurrence. In the absence of genital lesions, HSV was isolated from the genital area on 7% (95% CI 4%-11%) of days during a buttock recurrence and, among women, from the vulvar or cervical sites on 1% of days. Viral shedding of herpes simplex virus from the genital area is a relatively common occurrence during a buttock recurrence of genital herpes, even without concurrent genital lesions, reflecting perhaps reactivation from concomitant regions of the sacral neural ganglia. Patients with buttock herpes recurrences should be instructed about the risk of genital shedding during such recurrences. II-2.

    ABSTRACT Genital herpes simplex virus (HSV) reactivation is thought to be anatomically and temporally localized, coincident with limited ganglionic infection. Short, subclinical shedding episodes are the most common form of HSV-2 reactivation, with host clearance mechanisms leading to rapid containment. The anatomic distribution of shedding episodes has not been characterized. To precisely define patterns of anatomic reactivation, we divided the genital tract into a 22-region grid and obtained daily swabs for 20 days from each region in 28 immunocompetent, HSV-2-seropositive persons. HSV was detected via PCR, and sites of asymptomatic HSV shedding were subjected to a biopsy procedure within 24 h. CD4+ and CD8+ T cells were quantified by immunofluorescence, and HSV-specific CD4+ T cells were identified by intracellular cytokine cytometry. HSV was detected in 868 (7%) of 11,603 genital swabs at a median of 12 sites per person (range, 0 to 22). Bilateral HSV detection occurred on 83 (67%) days with shedding, and the median quantity of virus detected/day was associated with the number of sites positive (P genital tract and are associated with a localized cellular infiltrate that was demonstrated to be HSV specific in 3 cases. These data provide evidence that asymptomatic HSV-2 shedding contributes to chronic inflammation throughout the genital tract. IMPORTANCE This detailed report of the anatomic patterns of genital HSV-2 shedding demonstrates that HSV-2 reactivation can be detected at multiple bilateral sites in the genital tract, suggesting that HSV establishes latency throughout the sacral ganglia. In addition, genital biopsy specimens from sites of asymptomatic HSV shedding have increased numbers of CD8+ T cells compared to control tissue, and HSV-specific CD4+ T cells are found at sites of asymptomatic shedding. These findings suggest that widespread asymptomatic genital HSV-2 shedding is associated with a targeted host immune response and contributes to chronic

    The epidemiology, clinical course, diagnosis, and attempted treatments of herpes genitalis are reviewed. Herpes genitalis is an increasingly common sexually transmitted disease for which there is no effective treatment. It can occur in either sex and is mot commonly first found in patients 14 to 29 years old. Initial exposure to the virus may result in prolonged local symptoms (pain, itching, discharge) and signs (ulcerative lesions) as well as fever, malaise, myalgias, and fatigue. After the initial exposure, the virus may be found in a latent stage in the dorsal nerve root ganglia in the sacral area, and recurrences of disease may ensue. The frequency and clinical course of recurrent genital herpes can be of varying duration and severity. Although antiviral substances, immune potentiators, topical surfactants, and photodynamic inactivation have been used to treat genital herpes infections, there is no proven effective therapy.

    Patients with newly acquired genital herpes simplex virus 2 (HSV-2) infection have virus frequently detected at the genital mucosa. Rates of genital shedding initially decrease over time after infection, but data on long-term viral shedding are lacking. For this study, 377 healthy adults with history of symptomatic genital HSV-2 infection collected anogenital swabs for HSV-2 DNA polymerase chain reaction for at least 30 consecutive days. Time since first genital herpes episode was significantly associated with reduced genital shedding. Total HSV shedding occurred on 33.6% of days in participants <1 year, 20.6% in those 1-9 years, and 16.7% in those ≥10 years from first episode. Subclinical HSV shedding occurred on 26.2% of days among participants <1 year, 13.1% in those 1-9 years, and 9.3% in those ≥10 years from first episode. On days with HSV detection, mean quantity was 4.9 log₁₀ copies/mL for those <1 year, 4.7 log₁₀ copies/mL among those 1-9 years, and 4.6 log₁₀ copies/mL among those ≥10 years since first episode. Rates of total and subclinical HSV-2 shedding decrease after the first year following the initial clinical episode. However, viral shedding persists at high rates and copy numbers years after infection, and therefore may pose continued risk of HSV-2 transmission to sexual partners.

  20. Protection from genital herpes disease, seroconversion and latent infection in a non-lethal murine genital infection model by immunization with an HSV-2 replication-defective mutant virus.

    Viral vaccines have traditionally protected against disease, but for viruses that establish latent infection, it is desirable for the vaccine to reduce infection to reduce latent infection and reactivation. While seroconversion has been used in clinical trials of herpes simplex virus (HSV) vaccines to measure protection from infection, this has not been modeled in animal infection systems. To measure the ability of a genital herpes vaccine candidate to protect against various aspects of infection, we established a non-lethal murine model of genital HSV-2 infection, an ELISA assay to measure antibodies specific for infected cell protein 8 (ICP8), and a very sensitive qPCR assay. Using these assays, we observed that immunization with HSV-2 dl5-29 virus reduced disease, viral shedding, seroconversion, and latent infection by the HSV-2 challenge virus. Therefore, it may be feasible to obtain protection against genital disease, seroconversion and latent infection by immunization, even if sterilizing immunity is not achieved.

    The clinical course and complications of 268 patients with first episodes and 362 with recurrent episodes of genital herpes infection were reviewed. Symptoms of genital herpes were more severe in women than in men. Primary first-episode genital herpes was accompanied by systemic symptoms (67%), local pain and itching (98%), dysuria (63%), and tender adenopathy (80%). Patients presented with several bilaterally distributed postular ulcerative lesions that lasted a mean of 19.0 days. Herpes simplex virus was isolated from the urethra, cervix, and pharynx of 82%, 88%, and 13% of women with first-episode primary genital herpes, and the urethra and pharynx of 28% and 7% of men. Complications included aseptic meningitis (8%), sacral autonomic nervous system dysfunction (2%), development of extragenital lesions (20%), and secondary yeast infections (11%). Recurrent episodes were characterized by small vesicular or ulcerative unilaterally distributed lesions that lasted a mean of 10.1 days. Systemic symptoms were uncommon and 25% of recurrent episodes were asymptomatic. The major concerns of patients were the frequency of recurrences and fear of transmitting infection to partners or infants.

    No vaccines are approved for prevention or treatment of genital herpes. The focus of genital herpes vaccine trials has been on prevention using herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2) alone or combined with glycoprotein B. These prevention trials did not achieve their primary end points. However, subset analyses reported some positive outcomes in each study. The most recent trial was the Herpevac Trial for Women that used gD2 with monophosphoryl lipid A and alum as adjuvants in herpes simplex virus type 1 (HSV-1) and HSV-2 seronegative women. Unexpectedly, the vaccine prevented genital disease by HSV-1 but not HSV-2. Currently, HSV-1 causes more first episodes of genital herpes than HSV-2, highlighting the importance of protecting against HSV-1. The scientific community is conflicted between abandoning vaccine efforts that include gD2 and building upon the partial successes of previous trials. We favor building upon success and present approaches to improve outcomes of gD2-based subunit antigen vaccines.

    An effective vaccine for genital herpes has been difficult to achieve because of the limited efficacy of subunit vaccines and the safety concerns about live viruses. As an alternative approach, mutant herpes simplex virus strains that are replication-defective can induce protective immunity. To increase the level of safety and to prove that replication was not needed for immunization, we constructed a mutant herpes simplex virus 2 strain containing two deletion mutations, each of which eliminated viral replication. The double-mutant virus induces protective immunity that can reduce acute viral shedding and latent infection in a mouse genital model, but importantly, the double-mutant virus shows a phenotypic defect in latent infection. This herpes vaccine strain, which is immunogenic but has defects in both productive and latent infection, provides a paradigm for the design of vaccines and vaccine vectors for other sexually transmitted diseases, such as AIDS.

    Herpes simplex virus (HSV) infection in the newborn carries a high mortality rate and can result in lifelong neurologic impairment. The severity of HSV infection in the newborn has always dictated conservative management when prodromal symptoms or active genital lesions (or those suggestive of genital herpes) are present during labor and delivery. The risk of intrapartum infection, however, is related to the presence or absence of maternal immunity (neutralizing antibody) to HSV. The most significant risk of transmission is in first-episode primary infections with active lesions at delivery. Recent recommendations from the American Academy of Pediatrics Committees on Infectious Diseases and the Fetus and Newborn use rapid serologic and virologic screening in the management of asymptomatic infants born to mothers with active genital herpes. The revised guidelines highlight infants at greatest risk for HSV disease but do not apply to asymptomatic infants born to mothers with a history of HSV but no genital lesions at delivery. The current guidelines also stipulate that maternal serologic screening and molecular assays for HSV in newborn blood and cerebrospinal fluid must be available and reported in a timely fashion.

    In patients infected with human immunodeficiency virus (HIV), genital herpes can result in severe and atypical clinical presentations, and can become resistant to aciclovir treatment. Rarely, these manifestations may represent concurrent herpes simplex virus (HSV) with other agents. We report a 41-year-old black woman with HIV who presented with extensive and painful ulceration of the genitalia. Histological examination of a biopsy sample was suggestive of herpetic infection, and intravenous aciclovir was started, but produced only partial improvement. PCR was performed on the biopsy sample, and both HSV and cytomegalovirus (CMV) DNA was detected. Oral valganciclovir was started with therapeutic success. CMV infection is common in patients infected with HIV, but its presence in mucocutaneous lesions is rarely reported. This case exemplifies the difficulties of diagnosis of genital ulcers in patients infected with HIV. The presence of exuberant and persistent HSV genital ulcers in patients with HIV should also raise suspicions of the presence of co-infection with other organisms such as CMV. © 2014 British Association of Dermatologists.

    Genital herpes simplex virus type 2 (HSV-2) infection causes recurrent lesions and frequent viral shedding. GEN-003 is a candidate therapeutic vaccine containing HSV-2 gD2∆TMR and ICP4.2, and Matrix-M2 adjuvant. Persons with genital herpes were randomized into 3 dose cohorts to receive 3 intramuscular doses 21 days apart of 10 µg, 30 µg, or 100 µg of GEN-003, antigens without adjuvant, or placebo. Participants obtained genital swab specimens twice daily for HSV-2 detection and monitored genital lesions for 28-day periods at baseline and at intervals after the last dose. One hundred and thirty-four persons received all 3 doses. Reactogenicity was associated with adjuvant but not with antigen dose or dose number. No serious adverse events were attributed to GEN-003. Compared with baseline, genital HSV-2 shedding rates immediately after dosing were reduced with GEN-003 (from 13.4% to 6.4% for 30 μg [P genital HSV shedding and lesion rates.

    Sexually transmitted viruses cause chronic infections that have serious long-term health consequences. Based on the evidence from clinical and epidemiological studies, women carry a disproportionately higher burden of sexually transmitted diseases. The reasons for this are not well understood and possibly relate to a variety of social, behavioral and economic factors. In addition to these factors there are biological reasons that contribute to the higher prevalence in women. In this context it is critical to focus on and understand the local microenvironment of the female genital tract, since the majority of viral infections in women occur by heterosexual transmission. The genital tract is also the target site for initiation and maintenance of protective immune responses that could prevent or eliminate viral infections. The epithelial cells of the genital tract provide the first line of defense against viral entry. The interactions between each sexually transmitted virus and the genital epithelium are distinct and determine the outcome of exposure. They are also influenced by a number of factors in the local genital milieu. Among these factors are the female sex hormones that regulate both the susceptibility as well as immune responses to viral infections in the genital tract. Better understanding of the interactions of viruses with the local environment in the female genital tract will lead to development of novel methods to prevent sexually transmitted infections as well as to enhance innate and adaptive immunity.

    Development of more effective therapies for genital herpes simplex virus type-2 (HSV-2) infections remains a priority. The toll-like receptors (TLR) are attractive targets for the immunomodulation of primary and recurrent genital herpes infection. The guinea pig model of genital HSV-2 disease was therefore used to evaluate the efficacy of a new TLR-7 agonist, SMIP-7.7. The effects of SMIP-7.7 at concentrations between 0.90% and 0.09% were compared to the vehicle control or Aldara(®) (3M Health Care Limited, Northridge, CA, USA) as treatment for genital HSV-2 infections. Following intravaginal inoculation of Hartley guinea pigs with 10(6) pfu HSV-2 (MS strain), animals were treated intravaginally beginning at 36 h post-infection. Animals were evaluated for acute disease, acute virus replication, recurrent disease and shedding, as well as infection of the dorsal root ganglia. Treatment with SMIP-7.7 significantly decreased mean total lesion scores during primary infection (all doses, P<0.01 compared with vehicle control, and similar to Aldara(®)). Vaginal virus titres were reduced in treated animals compared with vehicle control (P<0.001 for each treatment versus vehicle control on day 4). Treatment with SMIP-7.7 also significantly decreased the number of recurrent lesion days, the number of days with recurrent virus shedding and the infection of the dorsal root ganglia compared to the vehicle control, and was similar to Aldara(®). As opposed to Aldara(®), SMIP-7.7 did not induce fever or weight loss during treatment. SMIP-7.7 improves the outcome of primary and recurrent HSV-2 disease comparable to Aldara(®) but without some of the side effects associated with Aldara(®).

    Depot-medroxyprogesterone acetate (DMPA) is a hormonal contraceptive especially popular in areas with high prevalence of HIV and other sexually transmitted infections (STI). Although observational studies identify DMPA as an important STI risk factor, mechanisms underlying this connection are undefined. Levonorgestrel (LNG) is another progestin used for hormonal contraception, but its effect on STI susceptibility is much less explored. Using a mouse model of genital herpes simplex virus type 2 (HSV-2) infection, we herein found that DMPA and LNG similarly reduced genital expression of the desmosomal cadherin desmoglein-1α (DSG1α), enhanced access of inflammatory cells to genital tissue by increasing mucosal epithelial permeability, and increased susceptibility to viral infection. Additional studies with uninfected mice revealed that DMPA-mediated increases in mucosal permeability promoted tissue inflammation by facilitating endogenous vaginal microbiota invasion. Conversely, concomitant treatment of mice with DMPA and intravaginal estrogen restored mucosal barrier function and prevented HSV-2 infection. Evaluating ectocervical biopsy tissue from women before and 1 month after initiating DMPA remarkably revealed that inflammation and barrier protection were altered by treatment identically to changes seen in progestin-treated mice. Together, our work reveals DMPA and LNG diminish the genital mucosal barrier; a first-line defense against all STI, but may offer foundation for new contraceptive strategies less compromising of barrier protection.

    We prospectively followed 39 adults with concurrent primary herpes simplex virus (HSV) infection (12 with HSV type 1 and 27 with HSV type 2) of the oropharynx and genitalia, caused by the same virus in each person, to evaluate the influence of viral type (HSV-1 vs. HSV-2) and site of infection (oropharyngeal vs. genital) on the frequency of recurrence. The subsequent recurrence patterns of HSV infection differed markedly according to viral type and anatomical site. Oral-labial recurrences developed in 5 of 12 patients with HSV-1 and 1 of 27 patients with HSV-2 (P less than 0.001). Conversely, genital recurrences developed in 24 of 27 patients with HSV-2 and 3 of 12 patients with HSV-1 (P less than 0.01). The mean rate of subsequent genital recurrences (due to HSV-1 and HSV-2) was 0.23 per month, whereas the mean rate of oral-labial recurrences was only 0.04 per month (P less than 0.001). The mean monthly frequencies of recurrence were, in order, genital HSV-2 infections, 0.33 per month; oral-labial HSV-1 infections, 0.12 per month; genital HSV-1 infections, 0.020 per month; and oral HSV-2 infections, 0.001 per month (P less than 0.01 for each comparison). We conclude that the likelihood of reactivation of HSV infection differs between HSV-1 and HSV-2 infections and between the sacral and trigeminal anatomical sites. The sixfold more frequent clinical recurrence rate of genital HSV infections as compared with oral-labial HSV infections may account for the relatively rapid increase in the prevalence of clinically recognized genital herpes in recent years.

    As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furthermore, the current possibilities of antiviral therapeutic interventions and laboratory diagnosis of genital herpes as well as the present situation and perspectives for the treatment by novel antivirals and prevention of disease by vaccination are presented. Since the medical management of patients with genital herpes simplex virus infection is often unsatisfactory, this review aims at all physicians and health professionals who are involved in the care of patients with genital herpes. The information provided would help to improve the counseling of affected patients and to optimize the diagnosis, treatment, and prevention of this particular disease.

  12. Diagnosis of genital herpes simplex virus infection in the clinical laboratory

    Since the type of herpes simplex virus (HSV) infection affects prognosis and subsequent counseling, type-specific testing to distinguish HSV-1 from HSV-2 is always recommended. Although PCR has been the diagnostic standard method for HSV infections of the central nervous system, until now viral culture has been the test of choice for HSV genital infection. However, HSV PCR, with its consistently and substantially higher rate of HSV detection, could replace viral culture as the gold standard for the diagnosis of genital herpes in people with active mucocutaneous lesions, regardless of anatomic location or viral type. Alternatively, antigen detection—an immunofluorescence test or enzyme immunoassay from samples from symptomatic patients--could be employed, but HSV type determination is of importance. Type-specific serology based on glycoprotein G should be used for detecting asymptomatic individuals but widespread screening for HSV antibodies is not recommended. In conclusion, rapid and accurate laboratory diagnosis of HSV is now become a necessity, given the difficulty in making the clinical diagnosis of HSV, the growing worldwide prevalence of genital herpes and the availability of effective antiviral therapy.

    Genital herpes (GH) causes genital ulcer disease, severe transient pain, and often paresthesias. Whether or not GH can cause urinary retention or chronic neuropathic pain is not well known. We present two immunocompetent patients with GH associated with neuropathic symptoms. We also review the literature on GH and associated neurologic problems. Patient 1 had primary herpes simplex virus (HSV)-2 infection with transient urinary retention and chronic bilateral neuropathic pain in the sacral area. Patient 2 had recurrent HSV-1 associated with unitaleral chronic neuropathic pain in the sacral area. Although transient urinary retention associated with GH is not uncommon, chronic neuropathic pain has not been reported previously. Our cases show that chronic neuropathic pain, that is "pain initiated or caused by a primary lesion or dysfunction in the nervous system," can follow genital HSV infection.

    We developed and morphologically characterized a human genital mucosa explant model (endocervix and ectocervix/vagina) to mimic genital herpes infections caused by herpes simplex virus types 1 (HSV-1) and 2 (HSV-2). Subsequent analysis of HSV entry receptor expression throughout the menstrual cycle in genital tissues was performed, and the evolution of HSV-1/-2 mucosal spread over time was assessed. Nectin-1 and -2 were expressed in all tissues during the entire menstrual cycle. Herpesvirus entry mediator expression was limited mainly to some connective tissue cells. Both HSV-1 and HSV-2 exhibited a plaque-wise mucosal spread across the basement membrane and induced prominent epithelial syncytia. © The Author 2014.

    Herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2) subunit antigen is included in many preclinical candidate vaccines. The rationale for including gD2 is to produce antibodies that block crucial gD2 epitopes involved in virus entry and cell-to-cell spread. HSV-2 gD2 was the only antigen in the Herpevac Trial for Women that protected against HSV-1 genital infection but not HSV-2. In that trial, a correlation was detected between gD2 ELISA titers and protection against HSV-1, supporting the importance of antibodies. A possible explanation for the lack of protection against HSV-2 was that HSV-2 neutralization titers were low, four-fold lower than to HSV-1. Here, we evaluated neutralization titers and epitope-specific antibody responses to crucial gD2 epitopes involved in virus entry and cell-to-cell spread as correlates of immune protection against genital lesions in immunized guinea pigs. We detected a strong correlation between neutralizing antibodies and protection against genital disease. We used a high throughput biosensor competition assay to measure epitope-specific responses to seven crucial gD2 linear and conformational epitopes involved in virus entry and spread. Some animals produced antibodies to most crucial epitopes while others produced antibodies to few. The number of epitopes recognized by guinea pig immune serum correlated with protection against genital lesions. We confirmed the importance of antibodies to each crucial epitope using monoclonal antibody passive transfer that improved survival and reduced genital disease in mice after HSV-2 genital challenge. We re-evaluated our prior study of epitope-specific antibody responses in women in the Herpevac Trial. Humans produced antibodies that blocked significantly fewer crucial gD2 epitopes than guinea pigs, and antibody responses in humans to some linear epitopes were virtually absent. Neutralizing antibody titers and epitope-specific antibody responses are important immune parameters to

    An estimated 417 million people worldwide ages 15 to 49 are infected with herpes simplex virus type 2 (HSV-2), the most common cause of genital ulcer disease. Some individuals experience frequent recurrences of genital lesions, while others only have subclinical infection, yet all risk transmitting infection to their intimate partners. A vaccine was developed that prevents shingles, which is a recurrent infection caused by varicella-zoster virus (VZV), a closely related member of the Herpesviridae family. The success of the VZV vaccine has stimulated renewed interest in a therapeutic vaccine for genital herpes. We have been evaluating a trivalent subunit antigen vaccine for prevention of genital herpes. Here, we assess the trivalent vaccine as immunotherapy in guinea pigs that were previously infected intravaginally with HSV-2. The trivalent vaccine contains HSV-2 glycoproteins C, D, and E (gC2, gD2, gE2) subunit antigens administered with CpG and alum as adjuvants. We previously demonstrated that antibodies to gD2 neutralize the virus while antibodies to gC2 and gE2 block their immune evasion activities, including evading complement attack and inhibiting activities mediated by the IgG Fc domain, respectively. Here, we demonstrate that the trivalent vaccine significantly boosts ELISA titers and neutralizing antibody titers. The trivalent vaccine reduces the frequency of recurrent genital lesions and vaginal shedding of HSV-2 DNA by approximately 50% and almost totally eliminates vaginal shedding of replication-competent virus, suggesting that the trivalent vaccine is a worthy candidate for immunotherapy of genital herpes.

    Herpes simplex virus types 1 and 2 are the main cause of genital ulcers worldwide. Although herpes simplex virus type 2 is the major cause of genital lesions, herpes simplex virus type 1 accounts for half of new cases in developed countries. Herpes simplex virus type 2 seroprevalence rises with sexual activity from adolescence through adulthood. Slovenian data in a high-risk population shows 16% seroprevalence of HSV-2. HSV-1 and HSV-2 DNA in genital swabs was detected in 19% and 20.7%, respectively. In most cases, genital herpes is asymptomatic. Primary genital infection with herpes simplex virus types 1 and 2 can be manifested by a severe clinical picture, involving the vesicular skin and mucosal changes and ulcerative lesions of the vulva, vagina, and cervix in women and in the genital region in men. Direct methods of viral genome detection are recommended in the acute stage of primary and recurrent infections when manifest ulcers or lesions are evident. Serological testing is recommended as an aid in diagnosing genital herpes in patients with reinfection in atypical or already healed lesions. When herpes lesions are present, all sexual activities should be avoided to prevent transmission of infection. Antiviral drugs can reduce viral shedding and thus reduce the risk of sexual transmission of the virus.

    Human immunodeficiency type 1 (HIV-1) continues to spread at an alarming rate. The virus may be transmitted through blood, genital secretions, and breast milk, and higher levels of systemic virus in the index case, as measured by plasma RNA viral load, have been shown to correlate with increased risk of transmitting HIV-1 both vertically and sexually. Less is known about the correlation between transmission and HIV-1 levels in breast milk or genital secretions, in part because reliable quantitative assays to detect HIV-1 in these fluids are not available. Here we show that the Gen-Probe HIV-1 viral load assay can be used to accurately quantify viral load in expressed breast milk and in cervical and vaginal samples collected on swabs. Virus could be quantified from breast milk and swab samples spiked with known amounts of virus, including HIV-1 subtypes A, C, and D. As few as 10 copies of HIV-1 RNA could be detected above background threshold levels in ≥77% of assays performed with spiked breast milk supernatants and mock swabs. In genital swab samples from HIV-1-infected women, similar levels of HIV-1 RNA were consistently detected in duplicate swabs taken from the same woman on the same clinic visit, suggesting that the RNA values from a single swab sample can be used to measure genital viral load.

    Genital shedding of herpes simplex virus (HSV) type 2 occurs frequently. Anatomic patterns of genital HSV-2 reactivation have not been intensively studied. Four HSV-2-seropositive women with symptomatic genital herpes attended a clinic daily during a 30-day period. Daily samples were collected from 7 separate genital sites. Swab samples were assayed for HSV DNA by quantitative polymerase chain reaction. Anatomic sites of clinical HSV-2 recurrences were recorded. HSV was detected on 44 (37%) of 120 days and from 136 (16%) of 840 swab samples. Lesions were documented on 35 (29%) of 120 days. HSV was detected at >1 anatomic site on 25 (57%) of 44 days with HSV shedding (median, 2 sites; range, 1-7), with HSV detected bilaterally on 20 (80%) of the 25 days. The presence of a lesion was significantly associated with detectable HSV from any genital site (incident rate ratio [IRR], 5.41; 95% confidence interval [CI], 1.24-23.50; P= .02) and with the number of positive sites (IRR, 1.19; 95% CI, 1. 01-1.40; P=.03). The maximum HSV copy number detected was associated with the number of positive sites (IRR, 1.62; 95% CI, 1.44-1.82; Pgenital tract. To prevent HSV-2 reactivation, suppressive HSV-2 therapy must control simultaneous viral reactivations from multiple sacral ganglia.

    Current treatment of genital herpes is focused on ameliorating signs and symptoms but is not curative. However, as potential herpes simplex virus (HSV) cure approaches are tested in the laboratory, we aimed to assess the interest in such studies by persons with genital herpes and the willingness to assume risks associated with experimental therapy. We constructed an anonymous online questionnaire that was posted on websites that provide information regarding genital herpes. The questions collected demographic and clinical information on adults who self-reported as having genital herpes, and assessed attitudes toward and willingness to participate in HSV cure clinical research. Seven hundred eleven participants provided sufficient responses to be included in the analysis. Sixty-six percent were women; the median age was 37 years, and the median time since genital HSV diagnosis was 4.7 years. The willingness to participate in trials increased from 59.0% in phase 1 to 68.5% in phase 2, and 81.2% in phase 3 trials, and 40% reported willingness to participate even in the absence of immediate, personal benefits. The most desirable outcome was the elimination of risk for transmission to sex partner or neonate. The mean perceived severity of receiving a diagnosis of genital HSV-2 was 4.2 on a scale of 1 to 5. Despite suppressive therapy available, persons with genital herpes are interested in participating in clinical research aimed at curing HSV, especially in more advanced stages of development.

    Herpes simplex virus-2 (HSV-2) is shed episodically, leading to occasional genital ulcers and efficient transmission. The biology explaining highly variable shedding patterns, in an infected person over time, is poorly understood. We sampled the genital tract for HSV DNA at several time intervals and concurrently at multiple sites, and derived a spatial mathematical model to characterize dynamics of HSV-2 reactivation. The model reproduced heterogeneity in shedding episode duration and viral production, and predicted rapid early viral expansion, rapid late decay, and wide spatial dispersion of HSV replication during episodes. In simulations, HSV-2 spread locally within single ulcers to thousands of epithelial cells in genital epithelium. DOI:http://dx.doi.org/10.7554/eLife.00288.001.

    Aim of the study was to determine clinical usefulness of direct immunofluorescence method in the laboratory diagnosis of genital herpes in women. Overall 187 anogenital swabs were collected from 120 women. Using a dacron-tipped applicator 83 swabs were collected from women suspected of genital herpes and 104 from patients with no signs of genital infection. All samples were tested using cell culture (Vero cell line) and then direct immunofluorescence method (DIF) for the identification of antigens of herpes simplex viruses: HSV-1 and HSV-2. Characteristic cytopathic effect (CPE), indicative of alphaherpesvirus infection, was observed in 43.4% of cultures with clinical specimens collected from women with suspected genital herpes and in 29.8% of cultures of clinical specimens taken from patients with no clinical symptoms of genital herpes. Herpes simplex viruses were determined in 73 samples by direct immunofluorescence method after amplification of the virus in cell culture. The DIF test confirmed the diagnosis based on the microscopic CPE observation in 85%. In 15% of samples (taken from pregnant women without clinical signs of infection) we reported positive immunofluorescence in the absence of CPE. The frequency of antigen detection was statistically significantly higher in samples that were positive by culture study (chi-square test with Yates's correction, p genital herpes in swabs taken from the vestibule of the vagina and the vulva. However, there was no statistically significant difference in the frequency of detection of Herpes Simplex Virus antigens in specimens from different parts of the genital tract in both groups of women (chi-square test, p > 0.05). In our study HHV-1 was the main causative agent of genital herpes. The growing worldwide prevalence of genital herpes, challenges with the clinical diagnosis, and availability of effective antiviral therapy are the main reasons for a growing interest in rapid, proper laboratory diagnosis of infected

    Current approved nucleoside therapies for genital herpes simplex virus (HSV) infections are effective but improved therapies are needed for treatment of both acute and recurrent diseases. The effects of N-methanocarbathymidine were evaluated and compared to acyclovir using guinea pig models of acute and recurrent infection. For acute disease following intravaginal inoculation of 10(6 )pfu HSV-2 (MS strain), animals were treated intraperitoneally beginning 24 h post-infection, and the effects on disease severity, vaginal virus replication, subsequent recurrences, and latent virus loads were evaluated. For evaluation of recurrent infection, animals were treated for 21 days beginning 14 days after infection and disease recurrence and recurrent shedding were evaluated. Treatment of the acute disease with N-methanocarbathymidine significantly reduced the severity of acute disease and decreased acute vaginal virus shedding more effectively than acyclovir. Significantly, none of the animals developed visible disease in the high-dose N-methanocarbathymidine group and this was the only group in which the number of days with recurrent virus shedding was reduced. Treatment of recurrent disease was equivalent to acyclovir when acyclovir was continuously supplied in the drinking water. N-methanocarbathymidine was effective as therapy for acute and recurrent genital HSV-2 disease in the guinea pig models. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Clinical observations indicate that herpes simplex virus type 1 (HSV-1) is significantly less likely than herpes simplex virus type 2 (HSV-2) to establish latency in (or reactivate from) sacral ganglionic tissue. In an effort to identify viral functions associated with latency, we analyzed HSV-1 isolates from three patients with established recurrent genital herpes and sought evidence of DNA sequences and proteins similar to those found in HSV-2. By restriction endonuclease cleavage patterns and by DNA hybridization analysis using either whole HSV-2 DNA or several cloned segments of HSV-2 DNA as probes, we found that the three HSV-1 isolates from patients with recurrent genital herpes showed no unusual homology to HSV-2 as compared with other HSV-1 isolates. Similarly, the proteins of these isolates could not be distinguished from those of other HSV-1 isolates and were distinct from those of HSV-2. At this level of resolution, there was no evidence to suggest that these recurrent genital HSV-1 isolates were intertypic recombinants, nor did they show any other unusual similarity to HSV-2.

    Intravaginal (ivag) or intranasal (i.n.) immunization of C57BL/6J (B6) mice with a thymidine kinase-deficient strain (tk-) of herpes simplex virus type 2 (HSV-2) resulted in comparable protection of the genital epithelium and sensory ganglia against HSV-2 challenge. In contrast, protection of these sites was much reduced in i.n.-immunized compared to ivag-immunized B cell-deficient μMT mice. Fewer HSV-specific T cells were detected in the genital epithelium of i.n.-immunized compared to ivag-immunized μMT mice after HSV-2 challenge. Passive transfer of HSV-specific serum to immune μMT mice restored protection of these sites against HSV-2 challenge. These results suggest that protection of genital and neuronal sites may be conferred by i.n. immunization but may be more dependent on antibody-dependent mechanisms than the protection resulting from genital immunization. These results have implications for immunization strategies to elicit high levels of cell-mediated protection of the genital tract and sensory ganglia

    Little is known about the role of herpes simplex virus (HSV) type 1 (HSV1) in the epidemiology of genital herpes in Canada. Data on herpes viral cultures for two consecutive years obtained from L'Hôpital Dr GL Dumont, which performs all the viral culture testing in New Brunswick, were reviewed. It was hypothesized that HSV1 was the main cause of genital herpes in New Brunswick. Samples of genital origin sent to the laboratory for HSV culture testing between July 2006 and June 2008 were analyzed. Samples from an unspecified or a nongenital source were excluded from analysis. Multiple positive samples collected from the same patient were pooled into a single sample. HSV was isolated from 764 different patients. HSV1 was isolated in 62.6% of patients (male, 55%; female, 63.8%). HSV1 was isolated in 73.2% of patients 10 to 39 years of age and in 32% of patients ≥40 years of age. The difference in rates of HSV1 infection between the 10 to 39 years of age group and the ≥40 years of age group was statistically significant (Pgenital site.

    Herpetic genital infection is a common sexually transmitted disease, caused in most cases by type 2 Herpes simplex virus (HSV2). This virus is characterized by its neurotropic properties and its ability to establish latency in sacral sensory ganglions. Some cases of genital primo-infection are complicated by viral replication dissemination to neigbhoring nerve structures like meninges and radicular terminations. In such cases muco-cutaneous manifestations are associated with peripheral neurological impairment in the form of meningo-radiculitis. Physicians should be familiar with these neurological symptoms knowing that they always regress completely. The present report illustrates these complications and reviews the potential neurological implications described in the literature.

    Infection with herpes simplex viruses 1 and 2 (HSV 1 and 2 or Human herpesvirus HHV) are one of the most common infections in human. Real time PCR is a sensitive and specific method for diagnostics of HHV infections. The aim of the study was to investigate the occurrence of HHV 1 and HHV 2 DNA in patient with clinical symptoms suggesting HHV infection. We used real time PCR to investigate swabs from genital and perianal lesions from 74 patients of the Department of Dermatology and Venereology Medical University Warsaw and of gynecological outpatient clinics in Warsaw 40 women and 34 men. The results were positive for HHV 2 in 25 cases (34%), for HHV 1 in 19 cases (26%) and for both viruses in 20 cases (27%). 10 samples were negative for both viruses. The results confirm that the main cause of symptomatic genital herpes is HHV 2, however the percentage of HHV 1 and specially of mixed HHV 1/HHV 2 infections was unexpectedly high.

    Herpes simplex virus type-2 (HSV-2) may heighten immune activation and increase human immunodeficiency virus 1 (HIV-1) replication, resulting in greater infectivity and faster HIV-1 disease progression. An 18-week randomized, placebo-controlled crossover trial of 500 mg valacyclovir twice daily in 20 antiretroviral-naive women coinfected with HSV-2 and HIV-1 was conducted and HSV-2 suppression was found to significantly reduce both HSV-2 and HIV-1 viral loads both systemically and the endocervical compartment. To determine the effect of HSV-2 suppression on systemic and genital mucosal inflammation, plasma specimens, and endocervical swabs were collected weekly from volunteers in the trial and cryopreserved. Plasma was assessed for concentrations of 31 cytokines and chemokines; endocervical fluid was eluted from swabs and assayed for 14 cytokines and chemokines. Valacyclovir significantly reduced plasma CXCL10 but did not significantly alter other cytokine concentrations in either compartment. These data suggest genital tract inflammation in women persists despite HSV-2 suppression, supporting the lack of effect on transmission seen in large scale efficacy trials. Alternative therapies are needed to reduce persistent mucosal inflammation that may enhance transmission of HSV-2 and HIV-1.

    We analysed 528 genital self-collected swabs (SCS) from 67 HIV-1 and herpes simplex virus type-2 (HSV-2) co-infected women collected during the placebo month of a randomized crossover clinical trial of suppressive acyclovir in Chiang Rai, Thailand. In this first longitudinal study of HIV-1 and HSV-2 co-infected women using genital SCS specimens, we found frequent mucosal HIV-1 shedding. Overall, 372 (70%) swabs had detectable HIV-1 RNA with median HIV-1 viral load of 2.61 log(10) copies/swab. We found no statistically significant association between detectable HIV-1 RNA and HSV-2 DNA in the same SCS specimen (adjusted odds ratio [aOR] 1.40; 95% confidence intervals [CI], 0.78-2.60, P = 0.25).

    Female mice were inoculated vaginally with the MS strain of herpes simplex virus type 2, and serially positive vaginal cultures were used to confirm infection. The proportion of mice infected and the mortality rate in infected mice decreased with increasing age. In mice 12 weeks old, clinical, neuropathologic, and virologic criteria defined four patterns of disease. Moribund mice had severe genital lesions, hindleg paralysis, and urinary and fecal retention, and most died during the second week of infection. These mice had a panmyelitis with a decreasing gradient of both viral antigen and lesions extending rostrally from the lumbosacral cord into the brain stem. Lesions were about equally distributed in gray and white matter and were characterized by neuronal loss and axonal demyelination, respectively. By contrast, mice with nonfatal infections had mild or no evident genital lesions and a small proportion had mild hindleg weakness. Of these, some mice had demyelinative lesions, particularly in the lower spinal cord but also at higher cord and brain stem levels, whereas others had leptomeningitis. Both of these groups had sacral sensory root abnormalities. A third group of survivors lacked both sensory root and central nervous system abnormalities. This report defines a broader spectrum of disease patterns following infection by a natural route than has been previously appreciated. It provides the first evidence that nonfatal herpes simplex virus type 2 infection by a peripheral route can produce central nervous system demyelination. It indicates that in aseptic meningitis with this agent, the route of virus spread to the central nervous system is neural and not hematogenous. Finally, the antigenic and pathologic observations presented here complement and confirm the virus isolation data and pathologic findings of others that genital herpes simplex virus type 2 infection causes ascending infection in the peripheral and central nervous system.

    Tenofovir is a potent anti-human immunodeficiency virus (HIV) agent that decreased risk of herpes simplex virus type 2 (HSV-2) acquisition in HIV pre-exposure prophylaxis trials. Whether tenofovir has utility in established HSV-2 disease is unclear. We randomized immunocompetent women with symptomatic HSV-2 infection to oral tenofovir disoproxil fumarate (TDF)/placebo vaginal gel, oral placebo/tenofovir (TFV) vaginal gel, or double placebo (ratio 2:2:1) in a one-way cross-over trial. Women collected genital swabs twice daily for HSV PCR during 4-week lead-in and 5-week treatment phases. The primary intent-to-treat end point was within-person comparison of genital HSV shedding and lesion rates. 64 women completed the lead-in phase and were randomized. Neither TDF nor TFV gel decreased overall shedding or lesion rate in the primary analysis; TFV gel decreased quantity of HSV DNA by -0.50 (-0.86-0.13) log10 copies/mL. In the per-protocol analysis, TDF reduced shedding (relative risk [RR] = 0.74, P = .006) and lesion rates (RR = 0.75, P = .032); quantity of virus shed decreased by 0.41 log10 copies/mL. Oral TDF modestly decreased HSV shedding and lesion rate, and quantity of virus shed when used consistently. Vaginal TFV gel decreased quantity of virus shed by 60%. In contrast to effects on HSV-2 acquisition, tenofovir is unlikely to provide clinically meaningful reductions in the frequency of HSV shedding or genital lesions. NCT01448616. © The Author 2015.

  3. Genital Herpes: A Review.

    Groves, Mary Jo

    2016-06-01

    Genital herpes is a common sexually transmitted disease, affecting more than 400 million persons worldwide. It is caused by herpes simplex virus (HSV) and characterized by lifelong infection and periodic reactivation. A visible outbreak consists of single or clustered vesicles on the genitalia, perineum, buttocks, upper thighs, or perianal areas that ulcerate before resolving. Symptoms of primary infection may include malaise, fever, or localized adenopathy. Subsequent outbreaks, caused by reactivation of latent virus, are usually milder. Asymptomatic shedding of transmissible virus is common. Although HSV-1 and HSV-2 are indistinguishable visually, they exhibit differences in behavior that may affect management. Patients with HSV-2 have a higher risk of acquiring human immunodeficiency virus (HIV) infection. Polymerase chain reaction assay is the preferred method of confirming HSV infection in patients with active lesions. Treatment of primary and subsequent outbreaks with nucleoside analogues is well tolerated and reduces duration, severity, and frequency of recurrences. In patients with HSV who are HIV-negative, treatment reduces transmission of HSV to uninfected partners. During pregnancy, antiviral prophylaxis with acyclovir is recommended from 36 weeks of gestation until delivery in women with a history of genital herpes. Elective cesarean delivery should be performed in laboring patients with active lesions to reduce the risk of neonatal herpes.

    With the decline in prevalence of childhood-acquired oral-labial herpes simplex type 1 infections in some populations and the increasing incidence of genital herpes infections in adults, clinicians are more likely to see patients with severe primary, first-episode genital herpes infections. Complications of these primary infections may include aseptic meningitis and urine retention secondary to sacral radiculopathy or autonomic dysfunction. Presented are the clinical course of first-episode and recurrent infections, complications, diagnostic laboratory methods, and results of controlled clinical trials evaluating the efficacy of topical, intravenous, and oral preparations of acyclovir.

    In 1994, an apparent outbreak of atypical genital ulcers was noted by clinicians at the sexually transmitted disease clinic in Jackson, Mississippi. Of 143 patients with ulcers tested with a multiplex polymerase chain reaction (PCR) assay, 56 (39%) were positive for Haemophilus ducreyi, 44 (31%) for herpes simplex virus, and 27 (19%) for Treponema pallidum; 12 (8%) were positive for > 1 organism. Of 136 patients tested for human immunodeficiency virus (HIV) by serology, 14 (10%) were HIV-seropositive, compared with none of 200 patients without ulcers (P chancroid were significantly more likely than male patients without ulcers to report sex with a crack cocaine user, exchange of money or drugs for sex, and multiple sex partners. The strong association between genital ulcers and HIV infection in this population highlights the urgency of preventing genital ulcers in the southern United States.

  6. A live-attenuated HSV-2 ICP0 virus elicits 10 to 100 times greater protection against genital herpes than a glycoprotein D subunit vaccine.

    Full Text Available Glycoprotein D (gD-2 is the entry receptor of herpes simplex virus 2 (HSV-2, and is the immunogen in the pharmaceutical industry's lead HSV-2 vaccine candidate. Efforts to prevent genital herpes using gD-2 subunit vaccines have been ongoing for 20 years at a cost in excess of $100 million. To date, gD-2 vaccines have yielded equivocal protection in clinical trials. Therefore, using a small animal model, we sought to determine if a live-attenuated HSV-2 ICP0⁻ virus would elicit better protection against genital herpes than a gD-2 subunit vaccine. Mice immunized with gD-2 and a potent adjuvant (alum+monophosphoryl lipid A produced high titers of gD-2 antibody. While gD-2-immunized mice possessed significant resistance to HSV-2, only 3 of 45 gD-2-immunized mice survived an overwhelming challenge of the vagina or eyes with wild-type HSV-2 (MS strain. In contrast, 114 of 115 mice immunized with a live HSV-2 ICP0⁻ virus, 0ΔNLS, survived the same HSV-2 MS challenges. Likewise, 0ΔNLS-immunized mice shed an average 125-fold less HSV-2 MS challenge virus per vagina relative to gD-2-immunized mice. In vivo imaging demonstrated that a luciferase-expressing HSV-2 challenge virus failed to establish a detectable infection in 0ΔNLS-immunized mice, whereas the same virus readily infected naïve and gD-2-immunized mice. Collectively, these results suggest that a HSV-2 vaccine might be more likely to prevent genital herpes if it contained a live-attenuated HSV-2 virus rather than a single HSV-2 protein.

The medical product of antiviral and immune modulating effect--fortepren (sodium polyprenyl phosphate) as a 4 mg/ml solution for injections combined with the base course of acyclic nucleoside acyclovir, 400 mg tablets, held studies. 40 male and female patients participated in the study. After a 10-day acyclovir course (400 mg x 3 times a day) for removing the acute phase, 4 groups of 10 individuals were formed: 1--5 ml (20 mg) of fortepren i/m once at day 13 ± 2 after the start of the study after the completion of the treatment of the acute phase of the disease; 2--5 ml (20 mg) fortepren i/m 3 times at an interval of 21 days; 3--2 ml (8 mg) fortepren i/m 3 times at an interval of 21 days; 4 (control)--5 ml of placebo i/m at remission stage 3 times at an interval of 21 days. Increase of the duration of inter-recurrence period, decrease of the severity of the recurrences, state of skin and mucous damage elements, improvements of immunologic parameters were considered during effectiveness evaluation. Significant differences in the frequency of recurrences of genital herpes were shown for 3 months of observation in experimental and control groups. A significant reduction of genital herpes recurrence frequency from 3.52 ± 0.09 (before treatment) to 2.89 ± 0.08 (after treatment) was noted in patients of group 3 (p genital herpes in the form of vesicle elements after treatment in groups 2 (p = 0.02) and 3 (p = 0.005) was found.

    Genital herpes is an incurable, chronic disease that affects millions of people worldwide. Not only does genital herpes cause painful, recurrent symptoms, it is also a significant risk factor for the acquisition of other sexually transmitted infections such as HIV-1. Antiviral drugs are used to treat herpes simplex virus (HSV) infection, but they cannot stop viral shedding and transmission. Thus, developing a vaccine that can prevent or clear infection will be crucial in limiting the spread of disease. In this review we outline recent studies that improve our understanding of host responses against HSV infection, discuss past clinical vaccine trials, and highlight new strategies for vaccine design against genital herpes.

    2015-04-01

    The genital tract mucosa is the site where sexually transmitted infections gain entry to the host. The immune response at this site is thus critical to provide innate protection against pathogens that are seen for the very first time as well as provide long-term pathogen-specific immunity, which would be required for an effective vaccine against sexually transmitted infection. A finely regulated immune response is therefore required to provide an effective barrier against pathogens without compromising the capacity of the genital tract to allow for successful conception and fetal development. We review recent developments in our understanding of the immune response in the female genital tract to infectious pathogens, using herpes simplex virus-2, human immunodeficiency virus-1 and Chlamydia trachomatis as examples, with a particular focus on the role of chemokines in orchestrating immune cell migration necessary to achieve effective innate and adaptive immune responses in the female genital tract.

    2012-10-01

    Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

    2006-01-01

    Background and Aim: Human papilloma viruses (HPVs) are small DNA tumor viruses that infect epithelial tissues and cause warts. One of the viral genes responsible for HPV's oncogenic activity is E6 which is known to inactivate the cellular p53 tumor suppressor gene. We aim to detect the presence of HPV infection and its different types in human warts, and to identify the relation between HPV and p53 expression in skin and genital lesions. Patients and Methods: We studied markers of HPV infection in overall of 30 patients (20 with common warts, and 10 with genital warts). Also, 30 normal skin samples were taken from each patient as a normal control. Detection of HPV was done using polymerase chain reaction (PCR), and HPV typing was performed using LiPA (Line immuno Probe Assay). In addition, all skin lesions were examined by immunohistochemistry for p53 expression. Results: In patients with common warts, HPV DNA was found in 4/20 (20%) of cases which was of HPV types 11, 31, 6, 33 (p=0.28). Also, P53 expression was found in 4/20 (20%) of cases (p=0.26). No single patient showed reactivity of both HPV and p53 expression. In patients with genital warts, however, HPV DNA was found in 6/10 (60%) of cases. Of these, 5 cases were positive for HPV type 6 and one case had HPV type 11. Three patients (30%) were positive for p53, and two of them (66%) were positive for both HPV and p53. In the normal skin control, 2/30 (6.6%) were positive for HPV DNA which were of types 5, and 31. Conclusions: We conclude that; (1) Prevalence rate of HPV infection in warts is higher than those of normal control group, and Egyptian patients with genital warts had higher prevalence rate of HPV than those with common warts, (2) In Egypt, HPV types 6, and 11 are the most prevalent genotypes associated with genital warts and HPV types 6, 11, 31, and 33 are associated with common warts, (3) There was no definite relation between p53 expression and HPV detection, (4) Also, there was no association

    Full Text Available Abstract Background CJ9-gD is a novel dominant-negative recombinant herpes simplex virus type 1 (HSV-1 that is completely replication-defective, cannot establish detectable latent infection in vivo, and expresses high levels of the major HSV-1 antigen glycoprotein D immediately following infection. In the present study, CJ9-gD was evaluated as a vaccine against HSV-2 genital infection in guinea pigs. Results Animals immunized with CJ9-gD developed at least 700-fold higher titers of HSV-2-specific neutralization antibodies than mock-immunized controls. After challenge with wild-type HSV-2, all 10 control guinea pigs developed multiple genital lesions with an average of 21 lesions per animal. In contrast, only 2 minor lesions were found in 2 of 8 CJ9-gD-immunized animals, representing a 40-fold reduction on the incidence of primary genital lesions in immunized animals (p Conclusions Collectively, we demonstrate that vaccination with the HSV-1 recombinant CJ9-gD elicits strong and protective immune responses against primary and recurrent HSV-2 genital disease and significantly reduces the extent of latent infection.

    Genital herpes is a common infection affecting some 20% of sexually active people. Although herpes simplex virus (HSV) types 1 and 2 can both establish genital latency, reactivation from the sacral ganglia favours HSV-2. Over the past decade the incidence of type 1 genital infection in women has greatly increased. To determine whether the increased prevalence of HSV-1 genital infection was benign or influencing the pattern of virus recovery in recurrent infection. A retrospective analysis of laboratory computer records was undertaken. Patients attending six genitourinary medicine (GUM) departments, over an 80 months period, were identified. Recurrent infection was confirmed where virus was recovered from at least two separate episodes of genital ulceration that were separated by an interval of 12 or more weeks. Episodes were further analysed for frequency, age, gender and virus type. Sixty nine patients with recurrent genital herpetic infection were identified. HSV-1 and HSV-2 were predominantly recovered from recurrent genital infections in females (34 HSV-1 vs. ten HSV-2) and males (one HSV-1 vs. 24 HSV-2), respectively (P>0.001). The mean age of females and males, at the initial diagnosis, was 26 and 39 years. There was no difference in the recurrence rate by type. HSV-1 has become the commonest cause of recurrent genital ulceration in Northern Ireland, almost entirely due its recent increased prevalence in women over the last decade. Women are experiencing genital herpetic infections at an earlier age than men.

    Genital herpes has a high global prevalence and burden of disease. This manuscript highlights recent advances in our understanding of genital herpes simplex virus (HSV) infections. Studies demonstrate a changing epidemiological landscape with an increasing proportion of genital herpes cases associated with HSV type 1. There is also growing evidence that the majority of infected individuals exhibit frequent, brief shedding episodes that are most often asymptomatic, which likely contribute to high HSV transmission rates. Given this finding as well as readily available serological assays, some have proposed that routine HSV screening be performed; however, this remains controversial and is not currently recommended. Host immune responses, particularly local CD4 and CD8 T cell activity, are crucial for HSV control and clearance following initial infection, during latency and after reactivation. Prior HSV immunity may also afford partial protection against HSV reinfection and disease. Although HSV vaccine trials have been disappointing to date and existing antiviral medications are limited, novel prophylactic and therapeutic modalities are currently in development. Although much remains unknown about genital herpes, improved knowledge of HSV epidemiology, pathogenesis and host immunity may help guide new strategies for disease prevention and control.

    Herpes simplex virus (HSV) infection of the neonate is uncommon, but genital herpes infections in adults are very common. Thus, although treating an infant with neonatal herpes is a relatively rare occurrence, managing infants potentially exposed to HSV at the time of delivery occurs more frequently. The risk of transmitting HSV to an infant during delivery is determined in part by the mother's previous immunity to HSV. Women with primary genital HSV infections who are shedding HSV at delivery are 10 to 30 times more likely to transmit the virus to their newborn infants than are women with recurrent HSV infection who are shedding virus at delivery. With the availability of commercial serological tests that reliably can distinguish type-specific HSV antibodies, it is now possible to determine the type of maternal infection and, thus, further refine management of infants delivered to women who have active genital HSV lesions. The management algorithm presented herein uses both serological and virological studies to determine the risk of HSV transmission to the neonate who is delivered to a mother with active herpetic genital lesions and tailors management accordingly. The algorithm does not address the approach to asymptomatic neonates delivered to women with a history of genital herpes but no active lesions at delivery.

    Herpes genitalis is one of the most common viral sexually transmitted diseases in the world, with an estimated seroprevalence in the US of greater than 20%. Two viruses of the same family cause herpes genitalis: herpes simplex virus 1 and 2. After the resolution of primary infection, the virus persists in the nerve roots of the sacral plexus, often causing recurrent (though generally less severe) outbreaks. These outbreaks, as well as the infectious potential to the patient's sexual partners, results in significant psychological stress on the patient, and has a tremendous negative impact on QOL. Current treatment modalities may result in a reduction in the number of outbreaks and viral shedding, but no cure exists. Although studies have clearly demonstrated the negative impact of recurrent genital herpes on QOL, an assessment scale specific to herpes was not developed until recently. Earlier studies indicated that patients did not perceive a significant benefit from episodic treatment with antivirals, but studies using the Recurrent Genital Herpes Quality of Life Questionnaire (RGHQoL) have now demonstrated that suppressive antiviral therapy improves quality of life in patients with frequent recurrences of genital herpes. However, not all patients with recurrent genital herpes need suppressive therapy, and proposed factors to consider include frequency of recurrence, physical and psychological distress caused by recurrences, and the potential for transmission to the patient's sexual partner. Newer therapeutic modalities, including the topical immune response modifier resiquimod and herpes vaccines, may eventually be shown to further decrease the psychological morbidity of recurrent genital herpes.

    Full Text Available This work, besides presenting the characteristics of the so-called genital stage regarding the alterations each one of the components of the drive suffer, examines the idea that the genital stage constitutes the integration —either biological or psychic— of the partial drives. In this sense, it aims to show, based on descriptions done by several thinkers not necessarily psychoanalysts, that the genitality, at least in its male version, turns out to be problematic since it introduces a relation of surprise in the order of the egoic representations of the individual as regards to its own sex organ. By this way, we paradoxically conclude that the genitality is the expression of a partial drive (as opposed to an apparent totality whose source is the penis. // Este trabajo, además de poner de presente las características de la llamada fase genital, en lo tocante a las modificaciones que se suceden en cada uno de los componentes de la pulsión, interroga la idea de que la fase genital constituye la integración acaso biológica, acaso psíquica- de las pulsiones parciales. En este sentido intenta mostrar, tomando como base descripciones hechas por varios pensadores no necesariamente psicoanalistas, que la genitalidad, al menos en su versión masculina, resulta problemática en la medida en que introduce una relación de extrañeza en el orden yoico, del sujeto respecto a su propio órgano sexual.

    Genital infections with herpes simplex virus type 2 (HSV-2) are a source of considerable morbidity and are a health concern for newborns exposed to virus during vaginal delivery. Additionally, HSV-2 infection diminishes the integrity of the vaginal epithelium resulting in increased susceptibility of individuals to infection with other sexually transmitted pathogens. Understanding immune protection against HSV-2 primary infection and immune modulation of virus shedding events following reactivation of the virus from latency is important for the development of effective prophylactic and therapeutic vaccines. Although the murine model of HSV-2 infection is useful for understanding immunity following immunization, it is limited by the lack of spontaneous reactivation of HSV-2 from latency. Genital infection of guinea pigs with HSV-2 accurately models the disease of humans including the spontaneous reactivation of HSV-2 from latency and provides a unique opportunity to examine virus-host interactions during latency. Although the guinea pig represents an accurate model of many human infections, relatively few reagents are available to study the immunological response to infection. To analyze the cell-mediated immune response of guinea pigs at extended periods of time after establishment of HSV-2 latency, we have modified flow-cytometry based proliferation assays and IFN-γ ELISPOT assays to detect and quantify HSV-specific cell-mediated responses during latent infection of guinea pigs. Here we demonstrate that a combination of proliferation and ELISPOT assays can be used to quantify and characterize effecter function of virus-specific immune memory responses during HSV-latency.

    Understanding the regional epidemiology of genital Herpes Simplex Virus (HSV) infections is important for clinical and public health practice, due to the increasing availability of type-specific serologic testing in Canada and the contribution of genital HSV-2 infection to ongoing HIV transmission. We used centralized laboratory data to describe trends in viral identifications of genital HSV in BC and assess the utility of these data for ongoing population surveillance. Records of viral identifications (1997-2005) were extracted from the Provincial Public Health Microbiology & Reference Laboratory database. Classification as genital or other site was based on documented specimen site. We conducted a descriptive analysis of trends over time, and calculated odds of HSV-1 infection among individuals with genital herpes. Of 48,183 viral identifications, 56.8% were genital, 10.0% were peri-oral and 9.1% cutaneous; site was unknown for 22.9%. Among genital identifications, HSV-1 infection was more likely in females, younger age groups, and later time periods. The proportion of genital herpes due to HSV-1 increased over time from 31.4% to 42.8% in BC. Our analysis of population-level laboratory data demonstrates that the proportion of genital herpes due to HSV-1 is increasing over time in BC, particularly among women and younger age groups; this has implications for clinical practice including the interpretation of type-specific serology. Provincial viral identification data are useful for monitoring the distribution of genital HSV-1 and HSV-2 infections over time. Improving clinical documentation of specimen site would improve the utility of these data.

    Herpes simplex virus 2 (HSV-2) subunit antigen vaccines targeting virus entry molecules have failed to prevent genital herpes in human trials. Our approach is to include a virus entry molecule and add antigens that block HSV-2 immune evasion. HSV-2 glycoprotein C (gC2) is an immune evasion molecule that inhibits complement. We previously reported that adding gC2 to gD2 improved vaccine efficacy compared to the efficacy of either antigen alone in mice and guinea pigs. Here we demonstrate that HSV-2 glycoprotein E (gE2) functions as an immune evasion molecule by binding the IgG Fc domain. HSV-2 gE2 is synergistic with gC2 in protecting the virus from antibody and complement neutralization. Antibodies produced by immunization with gE2 blocked gE2-mediated IgG Fc binding and cell-to-cell spread. Mice immunized with gE2 were only partially protected against HSV-2 vaginal challenge in mice; however, when gE2 was added to gC2/gD2 to form a trivalent vaccine, neutralizing antibody titers with and without complement were significantly higher than those produced by gD2 alone. Importantly, the trivalent vaccine protected the dorsal root ganglia (DRG) of 32/33 (97%) mice between days 2 and 7 postchallenge, compared with 27/33 (82%) in the gD2 group. The HSV-2 DNA copy number was significantly lower in mice immunized with the trivalent vaccine than in those immunized with gD2 alone. The extent of DRG protection using the trivalent vaccine was better than what we previously reported for gC2/gD2 immunization. Therefore, gE2 is a candidate antigen for inclusion in a multivalent subunit vaccine that attempts to block HSV-2 immune evasion. Herpes simplex virus is the most common cause of genital ulcer disease worldwide. Infection results in emotional distress for infected individuals and their partners, is life threatening for infants exposed to herpes during childbirth, and greatly increases the risk of individuals acquiring and transmitting HIV infection.

    Full Text Available Accurate identification of persons with genital herpes is necessary for optimal patient management and prevention of transmission. Because of inherent inaccuracies, clinical diagnosis of genital herpes should be confirmed by laboratory testing for the causative agents herpes simplex virus type 1 (HSV-1 and HSV type 2 (HSV-2. Further identification of the HSV type is valuable for counselling on the natural history of infection and risk of transmission. Laboratory methods include antigen detection, culture, polymerase chain reaction (PCR and conventional and type-specific serology (TSS. PCR has, by far, the greater sensitivity and should be the test of choice for symptomatic cases. HSV-2 TSS is indicated for patients with genital lesions in whom antigen detection, culture or PCR fail to detect HSV, and for patients who are asymptomatic but have a history suggestive of genital herpes. HSV-2 TSS is further indicated for patients infected with HIV. HSV-2 TSS along with HSV-1 TSS may be considered, as appropriate, in evaluating infection and/or immune status in couples discordant for genital herpes, women who develop their first clinical episode of genital herpes during pregnancy, asymptomatic pregnant women whose partners have a history of genital herpes or HIV infection, and women contemplating pregnancy or considering sexual partnership with those with a history of genital herpes. The above should be performed in conjunction with counselling of infected persons and their sex partners.

    Compartmentalization of HIV-1 between the genital tract and blood was noted in half of 57 women included in 12 studies primarily using cell-free virus. To further understand differences between genital tract and blood viruses of women with chronic HIV-1 infection cell-free and cell-associated virus populations were sequenced from these tissues, reasoning that integrated viral DNA includes variants archived from earlier in infection, and provides a greater array of genotypes for comparisons. Multiple sequences from single-genome-amplification of HIV-1 RNA and DNA from the genital tract and blood of each woman were compared in a cross-sectional study. Maximum likelihood phylogenies were evaluated for evidence of compartmentalization using four statistical tests. Genital tract and blood HIV-1 appears compartmentalized in 7/13 women by >/=2 statistical analyses. These subjects' phylograms were characterized by low diversity genital-specific viral clades interspersed between clades containing both genital and blood sequences. Many of the genital-specific clades contained monotypic HIV-1 sequences. In 2/7 women, HIV-1 populations were significantly compartmentalized across all four statistical tests; both had low diversity genital tract-only clades. Collapsing monotypic variants into a single sequence diminished the prevalence and extent of compartmentalization. Viral sequences did not demonstrate tissue-specific signature amino acid residues, differential immune selection, or co-receptor usage. In women with chronic HIV-1 infection multiple identical sequences suggest proliferation of HIV-1-infected cells, and low diversity tissue-specific phylogenetic clades are consistent with bursts of viral replication. These monotypic and tissue-specific viruses provide statistical support for compartmentalization of HIV-1 between the female genital tract and blood. However, the intermingling of these clades with clades comprised of both genital and blood sequences and the absence

    Despite the high prevalence of herpes simplex virus type 2 (HSV-2) in sub-Saharan Africa, the natural history of infection among Africans is not well characterized. We evaluated the frequency of genital HSV shedding in HIV-seropositive and HIV-seronegative men and women in Uganda. Ninety-three HSV-2-seropositive Ugandan adults collected anogenital swab specimens for HSV DNA quantification by polymerase chain reaction 3 times daily for 6 weeks. HSV-2 was detected from 2484 of 11 283 swab specimens collected (22%), with a median quantity of 4.3 log10 HSV copies/mL (range, 2.2-8.9 log10 HSV copies/mL). Genital lesions were reported on 749 of 3875 days (19%), and subclinical HSV shedding was detected from 1480 of 9113 swab specimens (16%) collected on days without lesions. Men had higher rates of total HSV shedding (relative risk [RR], 2.0 [95% confidence interval {CI}, 1.3-2.9]; P genital lesions (RR, 2.1 [95% CI, 1.2-3.4]; P = .005), compared with women. No differences in shedding rates or lesion frequency were observed based on HIV serostatus. HSV-2 shedding frequency and quantity are high among HSV-2-seropositive adults in sub-Saharan Africa, including persons with and those without HIV infection. Shedding rates were particularly high among men, which may contribute to the high prevalence of HSV-2 and early acquisition among African women. © The Author 2015.

    Herpes simplex virus 2 (HSV-2) infects the genital mucosa and establishes a life-long infection in sensory ganglia. After primary infection HSV-2 may reactivate causing recurrent genital ulcerations. HSV-2 infection is prevalent, and globally more than 400 million individuals are infected. As clinical trials have failed to show protection against HSV-2 infection, new vaccine candidates are warranted. The secreted glycoprotein G (sgG-2) of HSV-2 was evaluated as a prophylactic vaccine in mice using two different immunization and adjuvant protocols. The protocol with three intramuscular immunizations combining sgG-2 with cytosine-phosphate-guanine dinucleotide (CpG) motifs and alum induced almost complete protection from genital and systemic disease after intra-vaginal challenge with HSV-2. Robust immunoglobulin G (IgG) antibody titers were detected with no neutralization activity. Purified splenic CD4+ T cells proliferated and produced interferon-γ (IFN-γ) when re-stimulated with the antigen in vitro. sgG-2 + adjuvant intra-muscularly immunized mice showed a significant reduction of infectious HSV-2 and increased IFN-γ levels in vaginal washes. The HSV-2 DNA copy numbers were significantly reduced in dorsal root ganglia, spinal cord, and in serum at day six or day 21 post challenge. We show that a sgG-2 based vaccine is highly effective and can be considered as a novel candidate in the development of a prophylactic vaccine against HSV-2 infection.

    Genital herpes is one of the commonest sexually transmitted infections worldwide. Using the best available evidence, this guideline recommends strategies for diagnosis, management, and follow-up of the condition as well as for minimising transmission. Early recognition and initiation of therapy is key and may reduce the duration of illness or avoid hospitalisation with complications, including urinary retention, meningism, or severe systemic illness. The guideline covers a range of common clinical scenarios, such as recurrent genital herpes, infection during pregnancy, and co-infection with human immunodeficiency virus.

    To further understand the role that chronic viral infections of the male genital tract play on HIV-1 dynamics and replication. Retrospective, observational study including 236 paired semen and blood samples collected from 115 recently HIV-1 infected antiretroviral naive men who have sex with men. In this study, we evaluated the association of seminal HIV-1 shedding to coinfections with seven herpes viruses, blood plasma HIV-1 RNA levels, CD4 T-cell counts, presence of transmitted drug resistance mutations (DRMs) in HIV-1 pol, participants' age and stage of HIV-infection using multivariate generalized estimating equation methods. Associations between herpes virus shedding, seminal HIV-1 levels, number and immune activation of seminal T-cells was also investigated (Mann-Whitney). Seminal herpes virus shedding was observed in 75.7% of individuals. Blood HIV-1 RNA levels (P herpes virus (HHV)-8 levels (P herpes viruses seminal shedding in our cohort. Shedding of CMV, EBV and HHV-8 and absence of DRM were associated with increased frequency of HIV-1 shedding and/or higher levels of HIV-1 RNA in semen, which are likely important cofactors for HIV-1 transmission.

    Although the female genital tract is the main portal of entry for sexually transmitted infections in women, we still have limited understanding of the generation, maintenance and characteristics of memory T cells in the local tissue. Here, we utilized a mouse model of intravaginal HSV-2 infection and tetramers against the immunodominant HSV glycoprotein B epitope recognized by CD8+ T cells to examine the generation, maintenance and characteristics of anti-HSV memory T cells in the genital tract following acute infection. Our results show that the highest percentage of HSVgB-specific CD8+ T cells was found in the genital tract compared to the spleen or iliac lymphnode. Indeed, although the actual number of CD8+ T cells contracted following viral clearance, approximately one quarter of the CD8+ population that remained in the genital tissue was HSVgB-specific. Memory gB-tetramer+CD8 T cells in the genital tract were positive for CD127 and KLRG1 and negative for CD62L and CCR7, thus confirming that HSV-specific CD8 cells were effector memory T cells that lack the capacity for homing to lymphoid tissues. Functionally, both memory CD8+ and CD4+ HSV-specific populations in the genital tract produced IFNγ when stimulated in vitro and CD4+ cells also produced TNFα. Genital HSVgB-specific memory T cells expressed tissue-homing integrins CD103 (αE integrin) and CD49a (VLA-1 or α1 integrin). Our findings suggest that HSV-specific memory T cells are retained in the genital tract, poised to act as an early line of defense against future virus encounter.

    During the last decades, a changing epidemiological pattern of genital herpes simplex virus (HSV) infection has emerged. Primary infection is now caused as often by HSV-1 as by HSV-2. Once established, HSV can be reactivated leading to recurrent mucocutaneous lesions as well as meningitis. Why some otherwise immune-competent individuals experience severe and frequent recurrences is not known, and the immunological mechanism underlying recurrent symptomatic HSV infection is not fully understood. In this study, we investigate and characterise the immune response of patients with first episode of HSV genital infection and its relation to the frequency of symptomatic recurrences. In this cohort study, clinical and immunological data were collected from 29 patients who were followed 1 year after presenting with a first episode of genital or meningeal HSV infection. They were classified by PCR and serology as those with primary HSV-1, primary HSV-2 and non-primary HSV-2 infection. HSV-specific interleukin(Il)-4 and Il-10 responses at first visit were higher in primary infected HSV-2 infected patients experiencing lower numbers of recurrences during subsequent year. The median number of recurrences following primary HSV-2 genital infection may partly be predicted by the strength of an early HSV-specific IL-4 and IL-10 response.

    Full Text Available Genital ulcer disease (GUD prevalence increases in the first month of antiretroviral treatment (ART, followed by a return to baseline prevalence by month 3. Since most GUD is caused by herpes simplex virus type 2 (HSV-2, we hypothesized that genital HSV detection would follow a similar pattern after treatment initiation.We conducted a prospective cohort study of 122 HSV-2 and HIV-1 co-infected women with advanced HIV disease who initiated ART and were followed closely with collection of genital swab specimens for the first three months of treatment.At baseline, the HSV detection rate was 32%, without significant increase in genital HSV detection noted during the first month or the third month of ART. HIV-1 shedding declined during this period; no association was also noted between HSV and HIV-1 shedding during this period.Because other studies have reported increased HSV detection in women initiating ART and we have previously reported an increase in GUD during early ART, it may be prudent to counsel HIV-1 infected women initiating ART that HSV shedding in the genital tract may continue after ART initiation.

    Herpes simplex virus type 2 (HSV-2) invades human genital tract mucosa and following local replications can be rapidly transmitted via peripheral nerve axons to the sacral ganglia where it can establish latency. Reactivation of the latent viral reservoir results in recurrent ulcers in the genital region. Innate immunity, the first line of defence during both primary and recurrent genital herpes infections, is crucial during the period of acute infection to limit early virus replication and to facilitate the development of an appropriate specific acquired immunity. Recent developments in immunology reveal that the mammalian innate immune systems use Toll-like receptor (TLR) to specifically sense evolutionary conserved molecules such as bacterial DNA in pathogens. Recently, local-vaginal delivery of CpG containing oligodeoxynucleotide (ODN), a synthetic mimic of bacterial DNA, holds substantial promise as a strong inducer of innate immunity against genital herpes infections in the animal models of the disease. These preclinical observations provide a scientific ground work for introduction of this novel intervention strategy to clinic. This review aims to highlight recent developments and future challenges in use of immunostimulatory CpG ODN for inducing immunity against genital herpes infection and disease.

Clinical examination of the animals after challenge revealed that vaccination by both routes conferred some degree of protection, yet IV vaccination was clearly more effective in reducing the severity and duration of clinical disease. Furthermore, IV vaccination reduced the period of virus shedding in comparison with both groups. Taken together, these results demonstrate that SV265gE- is sufficiently attenuated upon IV vaccination in a low-titer dosis, is not readily reactivated after corticosteroid treatment and lastly, and more importantly, confers local protection upon challenge with a high titer of a virulent heterologous BoHV-1 isolate. Therefore, the use of this recombinant for genital immunization may be considered for prevention of BoHV-1-associated genital disease in the field.A infecção genital de novilhas ou vacas soronegativas pelo herpesvírus bovino tipo 1.2 (BoHV-1.2 pode resultar em vulvovaginite e infertilidade temporária.

    Context Since HSV-2 antibody tests have become commercially available, an increasing number of persons learn that they have genital herpes through serologic testing. The course of natural history of HSV-2 in asymptomatic, seropositive persons is uncertain. Objective To evaluate the virologic and clinical course of HSV genital shedding among participants with symptomatic and asymptomatic HSV-2 infection. Design, Setting and Participants Cohort of 498 immunocompetent HSV-2 seropositive persons enrolled in prospective studies of genital HSV shedding at the University of Washington Virology Research Clinic, Seattle, Washington, and Westover Heights Clinic in Portland, Oregon, between 1992 and 2008. Each participant obtained daily self-collected swabs of genital secretions for ≥ 30 days. Main Outcome Measurement The rate of viral shedding measured by quantitative real-time fluorescence polymerase chain reaction (PCR) for HSV DNA from genital swabs. Results HSV was detected on 4,753 of 23,683 days (20.1%; 95% CI, 18.3 to 22.0) in persons with symptomatic genital HSV-2 infection compared with 519 of 5,070 days (10.2%; 95% CI, 7.7 to 13.6) in persons with asymptomatic infection, pgenital viral shedding among persons with symptomatic genital HSV-2 infection compared with 85 of 519 days (16.4%; 95% CI, 11.2 to 23.9) among persons with asymptomatic infection, pgenital tract less frequently than persons with symptomatic infection, but much of the difference is attributable to less frequent genital lesions, as lesions are accompanied by frequent viral shedding.

    Herpes simplex virus (HSV) is one of the most prevalent viruses, with acute and recurrent infections in humans. The current gold standard for the diagnosis of HSV is viral culture which takes 2-14 days and has low sensitivity. In contrast, DNA amplification by polymerase chain reaction (PCR) can be performed within 1-2 h. We here describe a multiparameter PCR assay to simultaneously detect HSV-1 and HSV-2 DNA templates, together with integrated positive and negative controls, with product detection by melting curve analysis (MCA), in an array of semi-solid polyacrylamide gel posts. Each gel post is 0.67 μL in volume, and polymerized with all the components required for PCR. Both PCR and MCA can currently be performed in one hour and 20 min. Unprocessed genital swabs collected in universal transport medium were directly added to the reagents before or after polymerization, diffusing from atop the gel posts. The gel post platform detects HSV templates in as little as 2.5 nL of raw sample. In this study, 45 genital swab specimens were tested blindly as a preliminary validation of this platform. The concordance of PCR on gel posts with conventional PCR was 91%. The primer sequestration method introduced here (wherein different primers are placed in different sets of posts) enables the simultaneous detection of multiple pathogens for the same sample, together with positive and negative controls, on a single chip. This platform accepts unprocessed samples and is readily adaptable to detection of multiple different pathogens or biomarkers for point-of-care diagnostics.

    Genital herpes is a sexually transmitted disease. After the primary infection, the virus establishes a life-long latency in the sacral dorsal root ganglia. Recurrences may occur at an unpredictable rate. The clinical signs are not always easy to recognize and viral identification techniques may be helpful such as immunohistochemistry and in situ hybridization on Tzanck smears and muco-cutaneous biopsies. The treatment of genital herpes can follow one of three strategies using antiviral drugs, non-specific immunomodulators, and vaccination. The new oral antiviral drugs decrease the severity of clinical manifestations without, however, providing a definitive cure. In this article recent knowledge about the clinical aspects, differential diagnosis, diagnostic methods, treatment options and management is reviewed.

    Mucosal immunity consists of innate and adaptive immune responses which can be influenced by systemic immunity. Despite having been the subject of intensive studies, it is not fully elucidated what exactly occurs after HIV contact with the female genital tract mucosa. The sexual route is the main route of HIV transmission, with an increased risk of infection in women compared to men. Several characteristics of the female genital tract make it suitable for inoculation, establishment of infection, and systemic spread of the virus, which causes local changes that may favor the development of infections by other pathogens, often called sexually transmitted diseases (STDs). The relationship of these STDs with HIV infection has been widely studied. Here we review the characteristics of mucosal immunity of the female genital tract, its alterations due to HIV/AIDS, and the characteristics of coinfections between HIV/AIDS and the most prevalent STDs.

Conocida por síndrome pulmonar por virus Hanta, la infección americana se caracteriza por una serie de síntomas respiratorios similares a los de la influenza, con hipotensión grave y disnea progresiva que lleva a la insuficiencia respiratoria y, en 40 a 50% de los casos, a la defunción. Varias cepas virales son las responsables del trastorno y cada cepa tiene por reservorio una especie particular de roedores. El contagio se produce por inhalación de partículas de las materias excretadas por roedores infectados o por contacto con objetos contaminados. Hay datos que podrían indicar la posible transmisión del virus entre seres humanos. Ante la gravedad de este nuevo problema de salud pública, la OPS está intensificando las medidas para la detección y control del síndrome pulmonar por virus Hanta, entre las que figuran el establecimiento de una red de laboratorios encargados de diagnosticar la enfermedad, preparar reactivos para su detección, investigar la ecología del virus causal y mantener una vigilancia de casos activa.

Se ha demostrado que existe una elevada prevalencia de los poliomavirus humanos, BK y JC, en agua residual en todos los paí- ses estudiados, lo que implica la potencial transmisión de los virus y de genes potencialmente cancerígenos por vía oral. Estudios recientes demuestran que el patrón epidemiológico de la infección por VHE en países industrializados es complejo y que una gran diversidad de cepas del VHE infecta simultáneamente a la población. El control de la contaminación viral del medio ambiente requiere la estandarización de técnicas moleculares y el desarrollo de un programa de vigilancia que permita valorar parámetros víricos y reducir la diseminación de las enfermedades establecidas y de las infecciones víricas emergentes.

    Full Text Available Management of genital herpes is complex. Apart from using the standard antivirals, an ideal management protocol also needs to address various aspects of the disease, including the psychological morbidity. Oral acyclovir, valacyclovir or famciclovir are recommended for routine use. Long-term suppressive therapy is effective in reducing the number of recurrences and the risk of transmission to others. Severe or disseminated disease may require intravenous therapy. Resistant cases are managed with foscarnet or cidofovir. Genital herpes in human immunodeficiency virus-infected individuals usually needs a longer duration of antiviral therapy along with continuation of highly active anti retroviral therapy (HAART. Genital herpes in late pregnancy increases the risk of neonatal herpes. Antiviral therapy and/or cesarean delivery are indicated depending on the clinical circumstance. Acyclovir appears to be safe in pregnancy. But, there is limited data regarding the use of valacyclovir and famciclovir in pregnancy. Neonatal herpes requires a higher dose of acyclovir given intravenously for a longer duration. Management of the sex partner, counseling and prevention advice are equally important in appropriate management of genital herpes. Vaccines till date have been marginally effective. Helicase-primase inhibitors, needle-free mucosal vaccine and a new microbicide product named VivaGel may become promising treatment options in the future.

    Herpes simplex virus (HSV) entry requires multiple interactions at the cell surface and activation of a complex calcium signaling cascade. Previous studies demonstrated that integrins participate in this process, but their precise role has not been determined. These studies were designed to test the hypothesis that integrin αvβ3 signaling promotes the release of intracellular calcium (Ca2+) stores and contributes to viral entry and cell-to-cell spread. Transfection of cells with small interfering RNA (siRNA) targeting integrin αvβ3, but not other integrin subunits, or treatment with cilengitide, an Arg-Gly-Asp (RGD) mimetic, impaired HSV-induced Ca2+ release, viral entry, plaque formation, and cell-to-cell spread of HSV-1 and HSV-2 in human cervical and primary genital tract epithelial cells. Coimmunoprecipitation studies and proximity ligation assays indicated that integrin αvβ3 interacts with glycoprotein H (gH). An HSV-2 gH-null virus was engineered to further assess the role of gH in the virus-induced signaling cascade. The gH-2-null virus bound to cells and activated Akt to induce a small Ca2+ response at the plasma membrane, but it failed to trigger the release of cytoplasmic Ca2+ stores and was impaired for entry and cell-to-cell spread. Silencing of integrin αvβ3 and deletion of gH prevented phosphorylation of focal adhesion kinase (FAK) and the transport of viral capsids to the nuclear pore. Together, these findings demonstrate that integrin signaling is activated downstream of virus-induced Akt signaling and facilitates viral entry through interactions with gH by activating the release of intracellular Ca2+ and FAK phosphorylation. These findings suggest a new target for HSV treatment and suppression. Herpes simplex viruses are the leading cause of genital disease worldwide, the most common infection associated with neonatal encephalitis, and a major cofactor for HIV acquisition and transmission. There is no effective vaccine. These

We examined correlates of genital HIV-1 RNA in women who were seropositive for both herpes simplex virus (HSV-2 and HIV-1 and who were enrolled in a randomised controlled trial of HSV suppressive therapy (aciclovir 400 mg b.i.d vs. placebo in Tanzania.Samples, including a cervico-vaginal lavage, were collected and tested for genital HIV-1 and HSV and reproductive tract infections (RTIs at randomisation and 6, 12 and 24 months follow-up. Data from all women at randomisation and women in the placebo arm during follow-up were analysed using generalised estimating equations to determine the correlates of cervico-vaginal HIV-1 RNA detection and load.Cervico-vaginal HIV-1 RNA was detected at 52.0% of 971 visits among 482 women, and was independently associated with plasma viral load, presence of genital ulcers, pregnancy, bloody cervical or vaginal discharge, abnormal vaginal discharge, cervical ectopy, Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, an intermediate bacterial vaginosis score and HSV DNA detection. Similar factors were associated with genital HIV-1 RNA load.RTIs were associated with increased presence and quantity of genital HIV-1 RNA in this population. These results highlight the importance of integrating effective RTI treatment into HIV care services.

    Recently, there has been a marked increase in human papillomavirus (HPV) infection, and the etiological relationship between some HPV genotypes and genital cancer has been confirmed. Therefore, we used current molecular biology techniques to evaluate the prevalence of these viruses and their genotype in genital samples. We processed 401 genital samples from 281 women and 120 men, all with a diagnosis compatible with HPV infection. Virus was detected using PCR, and positive samples were typed using an array technique which enabled us to detect the 35 most common types of mucous-associated HPV. Of the 401 patients studied, 185 (46.1%) were positive, and only one type of HPV was detected in 133 cases. We found that 41.6% of the women and 56.7% of the men were positive. A total of 260 HPVs were typed; 154 were high oncogenic risk. They infected 16 men (23.5%) and 88 women (75.2%). The difference was statistically significant (pHVP 16 in 52 cases. We found a 46% prevalence of HPV infection. More than half of these patients were infected by high-risk HPV. The presence of high-risk HPV was significantly higher in women.

    Herpes simplex viruses type 1 and type 2 (HSV-1 and HSV-2) are amongst the most common human infectious viral pathogens capable of causing serious clinical diseases at every stage of life, from fatal disseminated disease in newborns to cold sores genital ulcerations and blinding eye disease. Primary mucocutaneous infection with HSV-1 & HSV-2 is followed by a lifelong viral latency in the sensory ganglia. In the majority of cases, herpes infections are clinically asymptomatic. However, in symptomatic individuals, the latent HSV can spontaneously and frequently reactivate, reinfecting the muco-cutaneous surfaces and causing painful recurrent diseases. The innate and adaptive mucosal immunities to herpes infections and disease remain to be fully characterized. The understanding of innate and adaptive immune mechanisms operating at muco-cutaneous surfaces is fundamental to the design of next-generation herpes vaccines. In this paper, the phenotypic and functional properties of innate and adaptive mucosal immune cells, their role in antiherpes immunity, and immunopathology are reviewed. The progress and limitations in developing a safe and efficient mucosal herpes vaccine are discussed. PMID:23320014

    To compare laboratory tests that can simultaneously detect and type herpes simplex virus (HSV) directly from the genital ulcer specimens in clinically suspected cases of genital herpes. A study was conducted over 10 months and 44 adult male and female patients clinically suspected with genital herpes were recruited. Genital ulcer swab specimens were subjected to glycoprotein-G gene-based conventional polymerase chain reaction (PCR) and commercially available direct fluorescent antibody (DFA) test and the results were compared. PCR for HSV was positive in 82% (36/44) cases. DFA was positive in 68.2% (30/44) cases. There was 100% agreement between HSV types detected by DFA and PCR. The strength of agreement between the results was better in primary genital herpes than recurrent cases. PCR was found to be better in the detection of HSV in recurrent genital herpes patients. It is a better modality, especially when genital herpes clinically presents with ulcerative or crusted lesions, and is also a cheaper alternative as compared to DFA.

In order to understand the role of local mucosal immunity in HSV-2 infection, T-cell lines were expanded from serial cervical cytobrush samples from 30 HSV-2-infected women and examined for reactivity to HSV-2. Approximately 3% of the CD3+ T cells isolated from the cervix were HSV-2 specific and of these, a median of 91.3% were CD4+, whereas a median of 3.9% were CD8+. HSV-2-specific CD4+ T cells expanded from the cervix were not only more frequent than CD8+ T cells but also exhibited greater breadth in terms of antigenic reactivity. T cells directed at the same HSV-2 protein were often detected in serial cervical cytobrush samples and in blood. Thus, broad and persistent mucosal T-cell responses to HSV-2 were detected in the female genital tract of HSV-2+ women suggesting that these cells are resident at the site of HSV-2 infection. Understanding the role of these T cells at this biologically relevant site will be central to the elucidation of adaptive immune mechanisms involved in controlling HSV-2 disease.

    Epidemiological studies consistently demonstrate synergy between herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus type 1 (HIV-1). Higher HIV-1 loads are observed in coinfected individuals, and conversely, HIV-1 is associated with more-severe herpetic disease. A small animal model of coinfection would facilitate identification of the biological mechanisms underlying this synergy and provide the opportunity to evaluate interventions. Mice transgenic for HIV-1 provirus and human cyclin T1 under the control of a CD4 promoter (JR-CSF/hu-cycT1) were intravaginally infected with HSV-2 and evaluated for disease progression, HIV shedding, and mucosal immune responses. HSV-2 infection resulted in higher vaginal HIV loads and genital tissue expression of HIV RNA, compared with HSV-uninfected JR-CSF/hu-cycT1 mice. There was an increase in genital tract inflammatory cells, cytokines, chemokines, and interferons in response to HSV-2, although the kinetics of the response were delayed in HIV-transgenic, compared with control mice. Moreover, the JR-CSF/hu-cycT1 mice exhibited earlier and more-severe neurological disease. The latter was associated with downregulation of secretory leukocyte protease inhibitor expression in neuronal tissue, a molecule with antiinflammatory, antiviral, and neuroprotective properties. JR-CSF/hu-cycT1 mice provide a valuable model to study HIV/HSV-2 coinfection and identify potential mechanisms by which HSV-2 facilitates HIV-1 transmission and HIV modulates HSV-2-mediated disease.

    Etiology, transmission and protection: Herpes simplex virus-2 (HSV-2) is a leading cause of sexually transmitted infections with recurring manifestations throughout the lifetime of infected hosts. Currently no effective vaccines or prophylactics exist that provide complete protection or immunity from the virus, which is endemic throughout the world. Pathology/Symptomatology: Primary and recurrent infections result in lesions and inflammation around the genital area and the latter accounts for majority of genital herpes instances. Immunocompromised patients including neonates are susceptible to additional systemic infections including debilitating consequences of nervous system inflammation. Epidemiology, incidence and prevalence: More than 500 million people are infected worldwide and most reported cases involve the age groups between 16-40 years, which coincides with an increase in sexual activity among this age group. While these numbers are an estimate, the actual numbers may be underestimated as many people are asymptomatic or do not report the symptoms. Treatment and curability: Currently prescribed medications, mostly nucleoside analogs, only reduce the symptoms caused by an active infection, but do not eliminate the virus or reduce latency. Therefore, no cure exists against genital herpes and infected patients suffer from periodic recurrences of disease symptoms for their entire lives. Molecular mechanisms of infection: The last few decades have generated many new advances in our understanding of the mechanisms that drive HSV infection. The viral entry receptors such as nectin-1 and HVEM have been identified, cytoskeletal signaling and membrane structures such as filopodia have been directly implicated in viral entry, host motor proteins and their viral ligands have been shown to facilitate capsid transport and many host and HSV proteins have been identified that help with viral replication and pathogenesis.

    Virtually all efforts to generate an effective protection against the life-long, recurrent genital infections caused by Herpes simplex virus-2 (HSV-2) have failed. Apart from sexual transmission, the virus can also be transmitted from mothers to neonates, and is a key facilitator of HIV co-acquisition. Here, we uncover a nanoimmunotherapy using specially designed Zinc Oxide Tetrapod Nanoparticles (ZOTEN) with engineered oxygen vacancies. We demonstrate that ZOTEN, when used intravaginally as a microbicide, is an effective suppressor of HSV-2 genital infection in female BALB/c mice. The strong HSV-2 trapping ability of ZOTEN significantly reduced the clinical signs of vaginal infection and effectively decreased animal mortality. In parallel, ZOTEN promoted the presentation of bound HSV-2 virions to mucosal antigen presenting cells, enhancing T cell- mediated and antibody-mediated responses to the infection, and thereby, suppressing a re-infection. We also found that ZOTEN exhibits strong adjuvant-like properties, which is highly comparable to alum, a commonly used adjuvant. Overall, our study provides very first evidence for the protective efficacy of an intravaginal microbicide/vaccine or microbivac platform against primary and secondary female genital herpes infections.

    Full Text Available Abstract Background Human papillomaviruses are the most common sexually transmitted infections, and genital warts, caused by HPV-6 and 11, entail considerable morbidity and cost. The natural history of genital warts in relation to HIV-1 infection has not been described in African women. We examined risk factors for genital warts in a cohort of high-risk women in Burkina Faso, in order to further describe their epidemiology. Methods A prospective study of 765 high-risk women who were followed at 4-monthly intervals for 27 months in Burkina Faso. Logistic and Cox regression were used to identify factors associated with prevalent, incident and persistent genital warts, including HIV-1 serostatus, CD4+ count, and concurrent sexually transmitted infections. In a subset of 306 women, cervical HPV DNA was tested at enrolment. Results Genital wart prevalence at baseline was 1.6% (8/492 among HIV-uninfected and 7.0% (19/273 among HIV-1 seropositive women. Forty women (5.2% experienced at least one incident GW episode. Incidence was 1.1 per 100 person-years among HIV-uninfected women, 7.4 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count >200 cells/μL and 14.6 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count ≤200 cells/μL. Incident genital warts were also associated with concurrent bacterial vaginosis, and genital ulceration. Antiretroviral therapy was not protective against incident or persistent genital warts. Detection of HPV-6 DNA and abnormal cervical cytology were strongly associated with incident genital warts. Conclusions Genital warts occur much more frequently among HIV-1 infected women in Africa, particularly among those with low CD4+ counts. Antiretroviral therapy did not reduce the incidence or persistence of genital warts in this population.

    Patients were recruited for hypnotherapy from a clinic for patients with frequently recurrent genital herpes simplex virus (rgHSV). Psychological and immunological parameters were measured 6 weeks prior to hypnotherapy and 6 weeks afterwards, during which time each patient kept a diary of symptoms of rgHSV. Following hypnotherapy there was a significant overall reduction in the number of reported episodes of rgHSV, accompanied by an increase in the numbers of CD3 and CD8 lymphocytes, which may represent a non specific effect of hypnosis. The improvers showed significant rises in natural killer (NK) cell counts, HSV specific lymphokine activated killer (LAK) activity, and reduced levels of anxiety when compared to non-improvers. NK cell numbers and HSV specific LAK activity may therefore be important in the reduction in rgHSV following hypnotherapy.

    Full Text Available FUNDAMENTOS: El virus West Nile (VWN es un Flavivirus que se transmite al hombre a través de distintas especies de mosquitos y produce brotes y casos esporádicos de enfermedad en distintas regiones del Viejo Mundo, incluída la Cuenca Mediterránea. Las zonas húmedas europeas que acogen aves migratorias procedentes de África constituyen áreas de alto riesgo para esta infección, así como para otras infecciones víricas transmitidas por artrópodos. MÉTODOS: Con objeto de investigar la prevalencia de la infección por el VWN y otros virus de transmisión similar en la población humana del Delta del Ebro, se estudiaron 1037 muestras de suero, obtenidas en 10 localidades de la zona, para presencia de anticuerpos frente a VWN y otros 12 virus transmitidos por artrópodos (3 Alfavirus, 8 Flaviviridae y 1 Bunyaviridae mediante titulación por inhibición de la hemaglutinación (IHA. En algunos casos se estudió la presencia de IgM específica por IHA tras fraccionar el suero por centrifugación en gradientes de sacarosa. RESULTADOS: En total, se encontró reactividad significativa frente a alguno de los virus probados en 130 casos (12.5%; 4.1% frente a Alfavirus, 8.0% frente a Flaviviridae y 0.4% frente a Bunyaviridae. El análisis de los títulos de anticuerpos reveló porcentajes significativos de muestras con títulos elevados frente a antígenos de VWN y otros. La distribución de la seroprevalencia fue muy desigual, concentrándose fundamentalmente en 3 localidades del interior del Delta (Ampolla, San Jaime y Montells, donde la prevalencia de anticuerpos frente a Flaviviridae llegó a alcanzar el 30% y se observaron niveles residuales de IgM frente a VWN en algunos sueros. CONCLUSIONES: Estos resultados y los obtenidos previamente en otras regiones de la Península Ibérica sugieren que el VWN circula en la población humana de las zonas de riesgo y produce brotes epidémicos periódicos.

    Type-specific serology (TSS) test for herpes simplex virus (HSV) have been used as a research tool in seroepidemiological studies for some years. However, TSS as a diagnostic modality for diagnosis of current episode of genital herpes is not well documented. To measure the seroprevalence of type-specific HSV Type 1 (HSV-1) and Type 2 (HSV-2) IgG antibodies in cases provisionally diagnosed as primary and recurrent genital herpes and to evaluate the role of TSS as a diagnostic modality for diagnosis of genital herpes versus polymerase chain reaction (PCR). A cross-sectional study was performed over a period of 10 months in which 44 adult patients with clinically suspected genital herpes were recruited. An in-house glycoprotein G gene base PCR was performed directly from the genital lesion specimen for simultaneous detection and typing of HSV. TSS was performed to detect IgG antibody against HSV-1 and 2 in all patients using commercially available kits, and the results were compared. Seroprevalence of HSV-1 IgG was 43% among primary and 65% among recurrent genital herpes cases (P = 0.22). Whereas that of HSV-2 IgG was found to be 14% and 83% in respective patient group (P = 0.0001). When compared to PCR results HSV-1 IgG detection in both primary and recurrent genital herpes diagnosis had poor specificity, positive predictive value, and sensitivity. Whereas, HSV-2 serology had a sensitivity of 13.33% and 73.33% in primary and recurrent genital herpes and specificity of 83.33% and 85.71%, respectively. HSV-2 IgG detection helps in strengthening the diagnosis of recurrent HSV-2 disease, whereas the absence of HSV-2 IgG antibody helps in excluding genital herpes as a likely cause of recurrent genital ulceration. However, detection of HSV-1 IgG antibody may not be useful for diagnosis in patients of genital ulcer disease.

    Ulcer material from consecutive patients attending clinics in Antananarivo, Madagascar, was tested using multiplex polymerase chain reaction (M-PCR) to detect Treponema pallidum, Haemophilus ducreyi, and herpes simplex virus. Sera were tested for syphilis and for IgG and IgM antibodies to Chlamydia trachomatis by microimmunofluorescence testing (MIF). By M-PCR, 33% of 196 patients had chancroid, 29% had syphilitic ulcers, and 10% had genital herpes; 32% of the ulcer specimens were M-PCR negative. Compared with M-PCR, syphilis serology was 72% sensitive and 83% specific. The sensitivity of clinical diagnosis of syphilis, chancroid, and genital herpes was 93%, 53%, and 0% and specificity was 20%, 52%, and 99%, respectively. Less schooling was associated with increased prevalence of syphilitic ulcers (P=.001). Sixteen patients (8%) were clinically diagnosed with lymphogranuloma venereum (LGV); 1 plausible case of LGV was found by MIF. In Madagascar, primary care of genital ulcers should include syndromic treatment for syphilis and chancroid.

  7. Herpes simplex virus-2 genital tract shedding is not predictable over months or years in infected persons.

    Full Text Available Herpes simplex virus-2 (HSV-2 is a chronic reactivating infection that leads to recurrent shedding episodes in the genital tract. A minority of episodes are prolonged, and associated with development of painful ulcers. However, currently, available tools poorly predict viral trajectories and timing of reactivations in infected individuals. We employed principal components analysis (PCA and singular value decomposition (SVD to interpret HSV-2 genital tract shedding time series data, as well as simulation output from a stochastic spatial mathematical model. Empirical and model-derived, time-series data gathered over >30 days consists of multiple complex episodes that could not be reduced to a manageable number of descriptive features with PCA and SVD. However, single HSV-2 shedding episodes, even those with prolonged duration and complex morphologies consisting of multiple erratic peaks, were consistently described using a maximum of four dominant features. Modeled and clinical episodes had equivalent distributions of dominant features, implying similar dynamics in real and simulated episodes. We applied linear discriminant analysis (LDA to simulation output and identified that local immune cell density at the viral reactivation site had a predictive effect on episode duration, though longer term shedding suggested chaotic dynamics and could not be predicted based on spatial patterns of immune cell density. These findings suggest that HSV-2 shedding patterns within an individual are impossible to predict over weeks or months, and that even highly complex single HSV-2 episodes can only be partially predicted based on spatial distribution of immune cell density.

    Herpes simplex virus is a frequent cause of recurrent ocular, oral, genital or cutaneous eruptions in man. Lesions are highly localized and tend to recur at the same site. Among the most consistent factors provoking recurrence is root section of the trigeminal nerve. Clinical and experimental data suggest that herpes simplex virus is commonly resident within the trigeminal ganglia of man, where it may be responsible for recurrent oral or lip lesions, and is less frequently a resident of the second or third sacral ganglia where it might be responsible for genital eruptions. Generally, the trigeminal virus is type 1 and the sacral virus is type 2; the virus is only rarely recoverable from other sensory ganglia. Factors provoking the reactivation from the virus' latent site and the mechanism for reactivation remain largely unknown. Further study is needed to understand the behavior of HSV and other viruses in nervous system tissue.

    T helper type 17 (Th17) cells play an important role in immunity to fungal and bacterial pathogens, although their role in the female genital tract, where exposure to these pathogens is common, is not well understood. We investigated the relationship between female genital tract infections, cervicovaginal interleukin-17 (IL-17) concentrations and Th17 cell frequencies. Forty-two cytokines were measured in cervicovaginal lavages from HIV-uninfected and HIV-infected women. Frequencies of Th17 cells (CD3(+) CD4(+) IL-17a(+)) were evaluated in cervical cytobrushes and blood by flow cytometry. Women were screened for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis and herpes simplex virus 2 by PCR, and candidal infections and bacterial vaginosis by Gram stain. Women with bacterial sexually transmitted infections (STIs), specifically chlamydia and gonorrhoea, had higher genital IL-17 concentrations than women with no STI, whereas women with candidal pseudohyphae/spores had lower IL-17 concentrations compared with women without candidal infections. Viral STIs (herpes simplex virus 2 and HIV) were not associated with significant changes in genital IL-17 concentrations. Genital IL-17 concentrations correlated strongly with other inflammatory cytokines and growth factors. Although Th17 cells were depleted from blood during HIV infection, cervical Th17 cell frequencies were similar in HIV-uninfected and HIV-infected women. Cervical Th17 cell frequencies were also not associated with STIs or candida, although few women had a STI. These findings suggest that IL-17 production in the female genital tract is induced in response to bacterial but not viral STIs. Decreased IL-17 associated with candidal infections suggests that candida may actively suppress IL-17 production or women with dampened IL-17 responses may be more susceptible to candidal outgrowth. © 2015 John Wiley & Sons Ltd.

  16. Coevolution of female and male genital components to avoid genital size mismatches in sexually dimorphic spiders.

    In most animal groups, it is unclear how body size variation relates to genital size differences between the sexes. While most morphological features tend to scale with total somatic size, this does not necessarily hold for genitalia because divergent evolution in somatic size between the sexes would cause genital size mismatches. Theory predicts that the interplay of female-biased sexual size dimorphism (SSD) and sexual genital size dimorphism (SGD) should adhere to the 'positive genital divergence', the 'constant genital divergence', or the 'negative genital divergence' model, but these models remain largely untested. We test their validity in the spider family Nephilidae known for the highest degrees of SSD among terrestrial animals. Through comparative analyses of sex-specific somatic and genital sizes, we first demonstrate that 99 of the 351 pairs of traits are phylogenetically correlated. Through factor analyses we then group these traits for MCMCglmm analyses that test broader correlation patterns, and these reveal significant correlations in 10 out of the 36 pairwise comparisons. Both types of analyses agree that female somatic and internal genital sizes evolve independently. While sizes of non-intromittent male genital parts coevolve with male body size, the size of the intromittent male genital parts is independent of the male somatic size. Instead, male intromittent genital size coevolves with female (external and, in part, internal) genital size. All analyses also agree that SGD and SSD evolve independently. Internal dimensions of female genitalia evolve independently of female body size in nephilid spiders, and similarly, male intromittent genital size evolves independently of the male body size. The size of the male intromittent organ (the embolus) and the sizes of female internal and external genital components thus seem to respond to selection against genital size mismatches. In accord with these interpretations, we reject the validity of the

    No herpes simplex virus 2 (HSV-2) vaccine has been licensed for use in humans. HSV-2 glycoproteins B (gB) and D (gD) are targets of neutralizing antibodies and T cells, but clinical trials involving intramuscular (i.m.) injection of HSV-2 gB and gD in adjuvants have not been effective. Here we evaluated intravaginal (ivag) genetic immunization of C57BL/6 mice with a replication-defective human papillomavirus pseudovirus (HPV PsV) expressing HSV-2 gB (HPV-gB) or gD (HPV-gD) constructs to target different subcellular compartments. HPV PsV expressing a secreted ectodomain of gB (gBsec) or gD (gDsec), but not PsV expressing a cytoplasmic or membrane-bound form, induced circulating and intravaginal-tissue-resident memory CD8(+) T cells that were able to secrete gamma interferon (IFN-γ) and tumor necrosis factor alpha (TNF-α) as well as moderate levels of serum HSV neutralizing antibodies. Combined immunization with HPV-gBsec and HPV-gDsec (HPV-gBsec/gDsec) vaccines conferred longer survival after vaginal challenge with HSV-2 than immunization with HPV-gBsec or HPV-gDsec alone. HPV-gBsec/gDsec ivag vaccination was associated with a reduced severity of genital lesions and lower levels of viral shedding in the genital tract after HSV-2 challenge. In contrast, intramuscular vaccination with a soluble truncated gD protein (gD2t) in alum and monophosphoryl lipid A (MPL) elicited high neutralizing antibody titers and improved survival but did not reduce genital lesions and viral shedding. Vaccination combining ivag HPV-gBsec/gDsec and i.m. gD2t-alum-MPL improved survival and reduced genital lesions and viral shedding. Finally, high levels of circulating HSV-2-specific CD8(+) T cells, but not serum antibodies, correlated with reduced viral shedding. Taken together, our data underscore the potential of HPV PsV as a platform for a topical mucosal vaccine to control local manifestations of primary HSV-2 infection. Genital herpes is a highly prevalent chronic disease caused by

    Genital herpes (GH), which is caused mainly by herpes simplex virus (HSV)-2 and HSV-1, remains a worldwide problem. Laboratory confirmation of GH is important, particularly as there are other conditions which present similarly to GH, while atypical presentations of GH also occur. Currently, virus culture is the classical method for diagnosis of GH, but it is time consuming and with low sensitivity. A major advance for diagnosis of GH is to use Real-time polymerase chain reaction (PCR). In this study, to evaluate the significance of the real-time PCR method in diagnosis and typing of genital HSV, the primers and probes targeted at HSV-1 DNA polymerase gene and HSV-2 glycoprotein D gene fraction were designed and applied to amplify DNA from HSV-1 or HSV-2 by employing the real-time PCR technique. Then the PCR reaction system was optimized and evaluated. HSV in swab specimens from patients with genital herpes was detected by real-time PCR. The real-time PCR assay showed good specificity for detection and typing of HSV, with good linear range (5×10(2)~5×10(8) copies/ml, r=0.997), a sensitivity of 5×10(2) copies/ml, and good reproducibility (intra-assay coefficients of variation 2.29% and inter-assay coefficients of variation 4.76%). 186 swab specimens were tested for HSV by real-time PCR, and the positive rate was 23.7% (44/186). Among the 44 positive specimens, 8 (18.2%) were positive for HSV-1 with a viral load of 8.5546×10(6) copies/ml and 36 (81.2%) were positive for HSV-2 with a viral load of 1.9861×10(6) copies/ml. It is concluded that the real-time PCR is a specific, sensitive and rapid method for the detection and typing of HSV, which can be widely used in clinical diagnosis of GH.

  3. Update on chancroid: an important cause of genital ulcer disease.

    1996-08-01

    Chancroid is a major cause of genital ulcer disease worldwide, and occurred at epidemic rates in the United States in the late 1980s. Though the recent epidemic in the U.S. appears to be waning, a number of areas continue to report significant numbers of cases. Chancroid is a particular concern, because, like other diseases that cause genital ulceration, it is associated with an increased risk for transmission or acquisition of human immunodeficiency virus (HIV). Recent studies have advanced the understanding of chancroid epidemiology, and new diagnostic tests may improve the ability to recognize and appropriately treat chancroid. Increased awareness of chancroid, with appropriate treatment for suspected lesions, along with public health efforts to implement prevention in high-risk populations, will be critical to prevent ongoing transmission of chancroid, and potentially ongoing transmission of HIV.

    Leukocytes participate in the immune control of herpes simplex virus (HSV). Data from HIV coinfections, germ line mutations, and case reports suggest involvement of CD4 T cells and plasmacytoid dendritic cells (pDC). We investigated the relationships between these cells and recurrent genital herpes disease severity in the general population. Circulating CD4 T-cell responses to HSV-2 were measured in specimens from 67 immunocompetent individuals with measured genital lesion and HSV shedding rates. Similarly, pDC number and functional responses to HSV-2 were analyzed in 40 persons. CD4 responses and pDC concentrations and responses ranged as much as 100-fold between persons while displaying moderate within-person consistency over time. No correlations were observed between these immune response parameters and genital HSV-2 severity. Cytomegalovirus (CMV) coinfection was not correlated with differences in HSV-2-specific CD4 T-cell responses. The CD4 T-cell response to HSV-2 was much more polyfunctional than was the response to CMV. These data suggest that other immune cell subsets with alternate phenotypes or anatomical locations may be responsible for genital herpes control in chronically infected individuals. PMID:22761381

    Lactobacillus colonization of the lower female genital tract provides protection from the acquisition of sexually transmitted diseases, including human immunodeficiency virus, and from adverse pregnancy outcomes. While glycogen in vaginal epithelium is thought to support Lactobacillus colonization in vivo, many Lactobacillus isolates cannot utilize glycogen in vitro. This study investigated how glycogen could be utilized by vaginal lactobacilli in the genital tract. Several Lactobacillus isolates were confirmed to not grow in glycogen, but did grow in glycogen-breakdown products, including maltose, maltotriose, maltopentaose, maltodextrins, and glycogen treated with salivary α-amylase. A temperature-dependent glycogen-degrading activity was detected in genital fluids that correlated with levels of α-amylase. Treatment of glycogen with genital fluids resulted in production of maltose, maltotriose, and maltotetraose, the major products of α-amylase digestion. These studies show that human α-amylase is present in the female lower genital tract and elucidates how epithelial glycogen can support Lactobacillus colonization in the genital tract. © The Author 2014.

    Immunotherapeutic vaccines have emerged as a novel treatment modality for genital herpes, a sexually transmitted disease mainly caused by herpes simplex virus type 2. The approaches to identify potential vaccine antigens have evolved from classic virus attenuation and characterization of antibody and T cell responses in exposed, but seronegative individuals, to systematic screens for novel T cell antigens. Combined with implementation of novel vaccine concepts revolving around immune evasion and local recruitment of immune effectors, the development of a safe and effective therapeutic vaccine is within reach. Here, we describe the vaccine approaches that currently show promise at clinical and pre-clinical stages and link them to the evolving scientific strategies that led to their identification.

    Genital inflammation is a key determinant of human immunodeficiency virus (HIV) transmission, and may increase HIV-susceptible target cells and alter epithelial integrity. Several genital conditions that increase HIV risk are more prevalent in African, Caribbean, and other black (ACB) women, including bacterial vaginosis and herpes simplex virus type-2 (HSV-2) infection. Therefore, we assessed the impact of the genital microbiota on mucosal immunology in ACB women and microbiome-HSV-2 interactions. Cervicovaginal secretions and endocervical cells were collected by cytobrush and Instead Softcup, respectively. T cells and dendritic cells were assessed by flow cytometry, cytokines by multiplex enzyme-linked immunosorbent assay (ELISA), and the microbiota by 16S ribosomal ribonucleic acid gene sequencing. The cervicovaginal microbiota of 51 participants were composed of community state types (CSTs) showing diversity (20/51; 39%) or predominated by Lactobacillus iners (22/51; 42%), L. crispatus (7/51; 14%), or L. gasseri (2/51; 4%). High-diversity CSTs and specific bacterial phyla (Gardnerella vaginalis and Prevotella bivia) were strongly associated with cervicovaginal inflammatory cytokines, but not with altered endocervical immune cells. However, cervical CD4+ T-cell number was associated with HSV-2 infection and a distinct cytokine profile. This suggests that the genital microbiota and HSV-2 infection may influence HIV susceptibility through independent biological mechanisms. © The Author 2017.

    Genital ulcers are a public health problem in developing countries. The World Health Organization recommends the use of syndromic guidelines for sexually transmitted infection treatment in resource-constrained countries. Monitoring local etiologies provides information that may aid policy for sexually transmitted infection treatment. We investigated the etiology of genital ulcer disease among outpatients in Lusaka, Zambia. Swabs from genital ulcers of 200 patients were tested using polymerase chain reaction for Treponema pallidum, herpes simplex virus types 1 (HSV-1) and 2 (HSV-2), Haemophilus ducreyi, and Chlamydia trachomatis. The prevalence of the detected pathogens was as follows; HSV-2, 28%; T. pallidum, 11.5%; C. trachomatis, 3%; HSV-1, 0.5%; and H. ducreyi, 0%. Coinfection with HSV-2 and T. pallidum was 1.5%, and coinfection of HSV-2 and C. trachomatis was 1%. In 55% of the patients, no etiologic diagnosis could be established. H. ducreyi was not detected, whereas HSV-2 and T. pallidum were the commonest pathogens. Nondetection of H. ducreyi requires further studies. If the present findings are validated, treatment guidelines would require to be revised in Zambia.

    It is well established that interferon gamma (IFN-γ) production by CD4 + T cells is critical for antiviral immunity against herpes simplex virus 2 (HSV-2) genital infection. However, the role of interleukin-17A (IL-17A) production by CD4 + T cells in HSV-2 antiviral immunity is yet to be elucidated. Here we demonstrate that IL-17A plays an important role in enhancing antiviral T helper type 1 (T h 1) responses in the female genital tract (FGT) and is essential for effective protection conferred by HSV-2 vaccination. While IL-17A did not play a critical role during primary genital HSV-2 infection, seen by lack of differences in susceptibility between IL-17A-deficient ( IL-17A -/- ) and wild-type (WT) C57BL/6 mice, it was critical for mediating antiviral responses after challenge/reexposure. Compared to WT mice, IL-17A -/- mice (i) infected intravaginally and reexposed or (ii) vaccinated intranasally and challenged intravaginally demonstrated poor outcomes. Following intravaginal HSV-2 reexposure or challenge, vaccinated IL-17A -/- mice had significantly higher mortality, greater disease severity, higher viral shedding, and higher levels of proinflammatory cytokines and chemokines in vaginal secretions. Furthermore, IL-17A -/- mice had impaired T h 1 cell responses after challenge/reexposure, with significantly lower proportions of vaginal IFN-γ + CD4 + T cells. The impaired T h 1 cell responses in IL-17A -/- mice coincided with smaller populations of IFN-γ + CD4 + tissue resident memory T (T RM ) cells in the genital tract postimmunization. Taken together, these findings describe a novel role for IL-17A in regulating antiviral IFN-γ + T h 1 cell immunity in the vaginal tract. This strategy could be exploited to enhance antiviral immunity following HSV-2 vaccination. IMPORTANCE T helper type 1 (T h 1) immunity, specifically interferon gamma (IFN-γ) production by CD4 + T cells, is critical for protection against genital herpesvirus (HSV-2) infection, and

    Full Text Available Frequency of cervical cancer related to Human Papilloma Virus (HPV has increased remarkably in less-developed countries. Hence, applying capable diagnostic methods is urgently needed, as is having a therapeutic strategy as an effective step for cervical cancer prevention. The aim of this study was to investigate the prevalence of various multi-type HPV infection patterns and their possible rising incidence in women with genital infections.This descriptive study was conducted on women who attended referral clinical laboratories in Tehran for genital infections from January 2012 until December 2013. A total of 1387 archival cervical scraping and lesion specimens were collected from referred women. HPV genotyping was performed using approved HPV commercial diagnostic technologies with either INNO-LiPA HPV or Geno Array Test kits.HPV was positive in 563 cases (40.59% with mean age of 32.35 ± 9.96. Single, multiple HPV genotypes and untypable cases were detected in 398 (70.69%, 160 (28.42% and 5 (0.89% cases, respectively. Multiple HPV infections were detected in 92 (57.5%, 42 (26.2%, 17 (10.6% and 9 (5.7% cases as two, three, four and five or more genotypes, respectively. The prevalence of 32 HPV genotypes was determined one by one. Seventeen HPV genotypes were identified in 95.78% of all positive infections. Five dominant genotypes, HPV6, 16, 53, 11 and 31, were identified in a total of 52.35%of the HPV positive cases.In the present study, we were able to evaluate the rate of multiple HPV types in genital infections. Nevertheless, it is necessary to evaluate the role of the dominant HPV low-risk types and the new probably high-risk genotypes, such as HPV53, in the increasing incidences of genital infections.

    Full Text Available A infecção genital de vacas pelo herpesvírus bovino tipo 1.2 (BoHV-1.2 pode resultar em vulvovaginite e infertilidade temporária. Após a infecção aguda, o BoHV-1 estabelece infecção latente, que pode cursar com episódios periódicos de reativação. O presente trabalho descreve os aspectos virológicos e clínico-patológicos da vulvovaginite aguda e infecção latente resultantes da inoculação de bezerras com uma amostra de BoHV-1.2 isolada de casos de balanopostite em touros. A inoculação do vírus em quatro bezerras pela via genital (10(8.1TCID50/animal resultou em replicação viral na mucosa genital e no desenvolvimento de vulvovaginite moderada a severa. Os animais inoculados excretaram o vírus nas secreções genitais até o dia 10 pós-inoculação (p.i. com título máximo de 10(7.3TCID50/mL. Foram observados congestão e edema da mucosa vulvovestibular, e formação de pequenas vesículas e pústulas. Durante a progressão clínica, as vesículas e pústulas aumentaram de tamanho e eventualmente se tornaram coalescentes e recobertas por um exsudato fino de coloração amarelada. Estes sinais foram observados a partir do dia 2 p.i. e aumentaram progressivamente de severidade até os dias 5-8 p.i. A administração de dexametasona no dia 55 p.i. resultou em excreção viral nas secreções genitais dos quatro animais por até 10 dias. A reativação da infecção latente foi acompanhada de recrudescência clínica, porém com sinais menos severos e com menor duração do que na infecção aguda. O DNA viral latente foi detectado por PCR, aos 36 dias pós-reativação (p.r., nos seguintes tecidos: gânglio sacrais: pudendo (4/4; genitofemoral e retal caudal (3/4 e obturador (4/4 e em alguns linfonodos regionais.

    Genital herpes is a prevalent sexually transmitted infection in the United States, occurring in almost 1 in 6 persons aged 14 to 49 years. Infection is caused by 2 subtypes of the herpes simplex virus (HSV), HSV-1 and HSV-2. Antiviral medications may provide symptomatic relief from outbreaks but do not cure HSV infection. Neonatal herpes infection, while uncommon, can result in substantial morbidity and mortality. To update the 2005 US Preventive Services Task Force (USPSTF) recommendation on screening for genital herpes. The USPSTF reviewed the evidence on the accuracy, benefits, and harms of serologic screening for HSV-2 infection in asymptomatic persons, including those who are pregnant, as well as the effectiveness and harms of preventive medications and behavioral counseling interventions to reduce future symptomatic episodes and transmission to others. Based on the natural history of HSV infection, its epidemiology, and the available evidence on the accuracy of serologic screening tests, the USPSTF concluded that the harms outweigh the benefits of serologic screening for genital HSV infection in asymptomatic adolescents and adults, including those who are pregnant. The USPSTF recommends against routine serologic screening for genital HSV infection in asymptomatic adolescents and adults, including those who are pregnant. (D recommendation).

    In recent years, there has been an increasing interest in immunomodulatory therapy as a means to treat various conditions, including infectious diseases. For instance, Toll-like receptor (TLR) agonists have been evaluated for treatment of genital herpes. However, although the TLR7 agonist imiquimod...... herpes simplex virus (HSV) 2 replication and improved the clinical outcome of infection. More importantly, local application of CDNs at the genital epithelial surface gave rise to local IFN activity, but only limited systemic responses, and this treatment conferred total protection against disease...... to TLRs, STING is expressed broadly, including in epithelial cells. Here we report that natural and non-natural STING agonists strongly induce type I IFNs in human cells and in mice in vivo, without stimulating significant inflammatory gene expression.

    BACKGROUND: Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong alkali that has been shown to be safe and effective for the treatment of genital warts and mollusc...

    Genital herpes simplex virus (HSV) infections are very common worldwide. Approximately 22% of pregnant women are infected genitally with HSV, and most of them are unaware of this. The most devastating consequence of maternal genital herpes is HSV disease in the newborn. Although neonatal HSV infections remain uncommon, due to the significant morbidity and mortality associated with the infection, HSV infection in the newborn is often considered in the differential diagnosis of ill neonates. This review summarizes the epidemiology and management of neonatal HSV infections and discusses strategies to prevent HSV infection in the newborn. Copyright © 2014 Elsevier Inc.

    Human papillomavirus (HPV) causes two types of external genital lesions (EGLs) in men: genital warts (condyloma) and penile intraepithelial neoplasia (PeIN). The purpose of this study was to describe genital HPV progression to a histopathologically confirmed HPV-related EGL. A prospective analysis nested within the HPV Infection in Men (HIM) study was conducted among 3033 men. At each visit, visually distinct EGLs were biopsied; the biopsy specimens were subjected to pathologic evaluation and categorized by pathologic diagnoses. Genital swabs and biopsies were used to identify HPV types using the Linear Array genotyping method for swabs and INNO-LiPA for biopsy specimens. EGL incidence was determined among 1788 HPV-positive men, and cumulative incidence rates at 6, 12, and 24 mo were estimated. The proportion of HPV infections that progressed to EGL was also calculated, along with median time to EGL development. Among 1788 HPV-positive men, 92 developed an incident EGL during follow-up (9 PeIN and 86 condyloma). During the first 12 mo of follow-up, 16% of men with a genital HPV 6 infection developed an HPV 6-positive condyloma, and 22% of genital HPV 11 infections progressed to an HPV 11-positive condyloma. During the first 12 mo of follow-up, 0.5% of men with a genital HPV 16 infection developed an HPV 16-positive PeIN. Although we expected PeIN to be a rare event, the sample size for PeIN (n=10) limited the types of analyses that could be performed. Most EGLs develop following infection with HPV 6, 11, or 16, all of which could be prevented with the 4-valent HPV vaccine. In this study, we looked at genital human papillomavirus (HPV) infections that can cause lesions in men. The HPV that we detected within the lesions could be prevented by a vaccine.

  5. A novel role for APOBEC3: Susceptibility to sexual transmission of murine acquired immunodeficiency virus (mAIDS) is aggravated in APOBEC3 deficient mice

    Science.gov (United States)

    2012-01-01

    Background APOBEC3 proteins are host factors that restrict infection by retroviruses like HIV, MMTV, and MLV and are variably expressed in hematopoietic and non-hematopoietic cells, such as macrophages, lymphocytes, dendritic, and epithelia cells. Previously, we showed that APOBEC3 expressed in mammary epithelia cells function to limit milk-borne transmission of the beta-retrovirus, mouse mammary tumor virus. In this present study, we used APOBEC3 knockout mice and their wild type counterpart to query the role of APOBEC3 in sexual transmission of LP-BM5 MLV – the etiological agent of murine AIDs (mAIDs). Results We show that mouse APOBEC3 is expressed in murine genital tract tissues and gametes and that genital tract tissue of APOBEC3-deficient mice are more susceptible to infection by LP-BM5 virus. APOBEC3 expressed in genital tract tissues most likely plays a role in decreasing virus transmission via the sexual route, since mice deficient in APOBEC3 gene have higher genitalia and seminal plasma virus load and sexually transmit the virus more efficiently to their partners compared to APOBEC3+ mice. Moreover, we show that female mice sexually infected with LP-BM5 virus transmit the virus to their off-spring in APOBEC3-dependent manner. Conclusion Our data indicate that genital tissue intrinsic APOBEC3 restricts genital tract infection and limits sexual transmission of LP-BM5 virus. PMID:22691411

    To assess the variation in HIV-1 over the menstrual cycle, including RNA levels in the female genital tract, plasma HIV-1-RNA levels, CD4 cell counts, and culturable virus. A prospective analysis of 55 HIV-1-infected women. Blood and genital tract specimens were collected weekly over 8 weeks, spanning two complete menstrual cycles. Applying repeated-measures models that used menses as the reference level, the variation in viral RNA levels was compared in endocervical canal fluid and cells (collected by Sno-strips and cytobrush, respectively) and ectocervicovaginal lavage (CVL) fluid. Repeated-measures models were also used to assess the variation in plasma CD4 cell counts and viral load. Shedding patterns differed among the three sampling methods, independent of genital tract co-infections. Genital tract HIV-1-RNA levels from CVL fluid and endocervical canal cytobrush specimens were highest during menses and lowest immediately thereafter (P = 0.001 and P = 0.04). The HIV-1-RNA level in endocervical canal fluid was highest in the week preceding menses (P = 0.003). The menstrual cycle had no effect on blood levels of RNA (P = 0.62), culturable virus (P = 0.34), or CD4 cell counts (P = 0.55). HIV-1-RNA levels were higher in endocervical canal fluid than in peripheral blood plasma during the late luteal phase (P = 0.03). HIV-1-RNA levels vary with the menstrual cycle in the female genital tract but not the blood compartment. HIV-1-RNA levels are higher in endocervical canal fluid than in blood plasma. These findings may have important implications for sex-specific pathogenesis, heterosexual transmission, and contraceptive hormone interventions in HIV-1-infected women.

    Subunit vaccines based on the herpes simplex virus 2 (HSV-2) glycoprotein D (gD-2) have been the major focus of HSV-2 vaccine development for the past 2 decades. Based on the promising data generated in the guinea pig model, a formulation containing truncated gD-2, aluminum salt, and MPL (gD/AS04) advanced to clinical trials. The results of these trials, however, were unexpected, as the vaccine protected against HSV-1 infection but not against HSV-2. To address this discrepancy, we developed a Depot medroxyprogesterone acetate (DMPA)-treated cotton rat Sigmodon hispidus model of HSV-2 and HSV-1 genital infection. The severity of HSV-1 genital herpes was less than that of HSV-2 genital herpes in cotton rats, and yet the model allowed for comparative evaluation of gD/AS04 immunogenicity and efficacy. Cotton rats were intramuscularly vaccinated using a prime boost strategy with gD/AS04 (Simplirix vaccine) or control vaccine formulation (hepatitis B vaccine FENDrix) and subsequently challenged intravaginally with HSV-2 or HSV-1. The gD/AS04 vaccine was immunogenic in cotton rats and induced serum IgG directed against gD-2 and serum HSV-2 neutralizing antibodies but failed to efficiently protect against HSV-2 disease or to decrease the HSV-2 viral load. However, gD/AS04 significantly reduced vaginal titers of HSV-1 and better protected animals against HSV-1 compared to HSV-2 genital disease. The latter finding is generally consistent with the clinical outcome of the Herpevac trial of Simplirix. Passive transfer of serum from gD/AS04-immunized cotton rats conferred stronger protection against HSV-1 genital disease. These findings suggest the need for alternative vaccine strategies and the identification of new correlates of protection. In spite of the high health burden of genital herpes, there is still no effective intervention against the disease. The significant gap in knowledge on genital herpes pathogenesis has been further highlighted by the recent failure of GSK

    Human immunodeficiency virus (HIV)-infected leukocytes have been detected in genital secretions from HIV-infected men and women and may play an important role in the sexual transmission of HIV. However, they have been largely overlooked in studies on mechanisms of HIV transmission and in the design and testing of HIV vaccine and microbicide candidates. This article describes the characteristics and quantities of leukocytes in male and female genital secretions under various conditions and also reviews evidence for the involvement of HIV-infected cells in both horizontal and vertical cell-associated HIV transmission. Additional research is needed in this area to better target HIV prevention strategies. © The Author 2014. Published by Oxford University Press on behalf of the Infectious Diseases Society of America.

    2015-03-01

    Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) are highly prevalent viruses capable of establishing lifelong infection. Genital herpes in women of childbearing age represents a major risk for mother-to-child transmission (MTCT) of HSV infection, with primary and first-episode genital HSV infections posing the highest risk. The advent of antiviral therapy with parenteral acyclovir has led to significant improvement in neonatal HSV disease mortality. Further studies are needed to improve the clinician's ability to identify infants at increased risk for HSV infection and prevent MTCT, and to develop novel antiviral agents with increased efficacy in infants with HSV infection.

    Episodic acyclovir therapy has been added to genital ulcer disease (GUD) syndromic management guidelines in several sub-Saharan African countries with human immunodeficiency virus (HIV) epidemics. We examined the correlates of health care seeking in men with GUD and its relationship to HIV-1 and herpes simplex virus type 2 outcomes. Men with GUD (n = 615) were recruited from primary health care clinics in Gauteng province, South Africa for a randomized controlled trial of episodic acyclovir therapy. We used baseline survey and sexually transmitted infection/HIV-testing data to examine delay in health care seeking (defined as time from ulcer recognition to baseline study visit). Median delay in health care seeking for GUD was 5 days, and one-quarter of men had previously sought care for the current ulcer. Previous care seekers were older, had more episodes of ulceration in the past year, and were more likely to test seropositive for HIV-1 and HSV-2. Delay in health care seeking was significantly associated with age, education level, and sex during the ulceration episode. Delays in care seeking were related to poorer HIV-1 outcomes; these findings were valid after controlling for advanced HIV. Interventions to help shorten the duration between ulcer recognition and health care seeking for men with GUD are needed.

    Targeting the mucosal immune system of the genital tract (GT) with subunit vaccines failed to induce potent and durable local CD8+ T cell immunity, crucial for protection against many sexually transmitted viral (STV) pathogens, including herpes simplex virus type 2 (HSV-2) that causes genital herpes. In this study, we aimed to investigate the potential of a novel lipopeptide/adenovirus type 5 (Lipo/rAdv5) prime/boost mucosal vaccine for induction of CD8+ T cell immunity to protect the female genital tract from herpes. The lipopeptide and the rAdv5 vaccine express the immunodominant HSV-2 CD8+ T cell epitope (gB498-505) and both were delivered intravaginally (IVAG) in the progesterone-induced B6 mouse model of genital herpes. Compared to its homologous lipopeptide/lipopeptide (Lipo/Lipo); the Lipo/rAdv5 prime/boost immunized mice: (i) developed potent and sustained HSV-specific CD8+ T cells, detected in both the GT draining nodes (GT-DLN) and in the vaginal mucosa (VM); (ii) had significantly lower virus titers; (iii) had decreased overt signs of genital herpes disease; and (iv) did not succumb to lethal infection (p herpes infection and disease.

    The aim of the present study was to investigate the effects of Longdanxiegan formula granule (LDXGFG), a Chinese traditional medicine on Toll-like receptor (TLR) pathway in recurrent genital herpes. An experimental recurrent genital herpes model was constructed using herpes guinea pig model. The effect of LDXGFG on expression levels of TLR pathway genes were detected using real-time polymerase chain reaction. Furthermore, the dendritic cells and Langerhans cells were isolated and the TLR pathway genes of these cells were assayed after LDXGFG treatment. The result suggested two different expression patterns of TLR pathway genes in genital herpes and recurrent genital herpes, including upregulated genes and downregulated genes. TLR1, TLR4, TLR6, TLR7, TLR8, TLR9, and TLR10 showed a significant decrease while, TLR2, TLR3, and TLR5 increased in genital herpes and recurrent genital herpes guinea pigs. Meanwhile, the downregulated genes in genital herpes and recurrent genital herpes were stimulated by LDXGFG. By contrast, the upregulated genes decreased significantly after LDXGFG treatment. In both dendritic cells and Langerhans cells, the TLR pathway genes exhibited same pattern: the LDXGFG corrected the abnormal expression of TLR pathway genes. The present results suggest that LDXGFG is an alternative, inexpensive, and lasting-effect medicine for herpes simplex virus 2 infection. Copyright © 2016. Published by Elsevier B.V.

  1. Unusual Initial Presentation of Herpes Simplex Virus as Inguinal Lymphadenopathy

    Sarah A. Fleming

    2015-01-01

    Full Text Available Genital herpes simplex virus (HSV infections are a common cause of inguinal lymphadenopathy. However, surgical excision of enlarged inguinal nodes is almost never performed to initially diagnose genital herpes simplex virus, due to the distinct external presentation of genital herpetic vesicles that usually occur with the first symptoms of infection. Therefore, the histologic and immunophenotypic features of HSV-associated inguinal lymphadenopathy are unfamiliar to most pathologists. The current report describes the lymph node pathology of two immunocompetent patients, whose initial HSV diagnosis was established through surgical excision of enlarged inguinal lymph nodes. Histologic examination showed features consistent with viral lymphadenopathy, including florid follicular hyperplasia, monocytoid B-cell hyperplasia, and paracortical hyperplasia without extensive necrosis. Immunohistochemical stains for HSV antigens, using polyclonal anti-HSV I and II antibodies, demonstrate strong immunoreactivity for HSV in a small number of cells in the subcapsular sinuses, especially in areas with monocytoid B-cell hyperplasia. Rare scattered HSV-positive cells also are identified in paracortical areas and germinal centers. We conclude that an initial diagnosis of genital HSV infection may be established by inguinal lymph node biopsy.

    The practice of female genital mutilation predates the founding of both Christianity and Islam. Though largely confined among Muslims, the operation is also practiced in some Christian communities in Africa such that female genital mutilation takes place in various forms in more than twenty African countries, Oman, Yemen, the United Arab Emirates, and by some Muslims in Malaysia and Indonesia. In recent decades, ethnic groups which practice female genital mutilation have immigrated to Britain. The main groups are from Eritrea, Ethiopia, Somalia, and Yemen. In their own countries, an estimated 80% of women have had the operation. Female genital mutilation has been illegal in Britain since 1985, but it is practiced illegally or children are sent abroad to undergo the operation typically at age 7-9 years. It is a form of child abuse which poses special problems. The authors review the history of female genital mutilation and describe its medical complications. Assuming that the size of the population in Britain of ethnic groups which practice or favor female genital mutilation remains more or less unchanged, adaptation and acculturation will probably cause the practice to die out within a few generations. Meanwhile, there is much to be done. A conspiracy of silence exists in medical circles as well as widespread ignorance. Moreover, none of a number of well-known obstetric and pediatric textbooks mentions female genital mutilation, while the National Society for the Prevention of Cruelty to Children has neither information nor instructional material. It is high time that the problem was more widely and openly discussed.

  5. Anti-gp120 minibody gene transfer to female genital epithelial cells protects against HIV-1 virus challenge in vitro.

    Full Text Available Although cervico-vaginal epithelial cells of the female lower genital tract provide the initial defense system against HIV-1 infection, the protection is sometimes incomplete. Thus, enhancing anti-HIV-1 humoral immunity at the mucosal cell surface by local expression of anti-HIV-1 broadly neutralizing antibodies (BnAb that block HIV-1 entry would provide an important new intervention that could slow the spread of HIV/AIDS.This study tested the hypothesis that adeno-associated virus (AAV-BnAb gene transfer to cervico-vaginal epithelial cells will lead to protection against HIV-1. Accordingly, a recombinant AAV vector that encodes human b12 anti-HIV gp120 BnAb as a single-chain variable fragment Fc fusion (scFvFc, or "minibody" was constructed. The secreted b12 minibody was shown to be biologically functional in binding to virus envelope protein, neutralizing HIV-1 and importantly, blocking transfer and infectivity of HIV-1(bal in an organotypic human vaginal epithelial cell (VEC model. Furthermore, cervico-vaginal epithelial stem cells were found to be efficiently transduced by the optimal AAV serotype mediated expression of GFP.This study provides the foundation for a novel microbicide strategy to protect against sexual transmission of HIV-1 by AAV transfer of broadly neutralizing antibody genes to cervico-vaginal epithelial stem cells that could replenish b12 BnAb secreting cells through multiple menstrual cycles.

  6. Epidemiology and Natural History of Human Papillomavirus Infections in the Female Genital Tract

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Human papillomavirus (HPV is the most common newly diagnosed sexually transmitted infection in the United States. Although the majority of sexually active adults will be infected with HPV at least once in their lives, it is sexually active women less than 25 years of age who consistently have the highest rates of infection. Besides youth and gender, common risk factors for HPV infection and clinical sequelae of infection include high number of sexual partners and coinfection with Chlamydia trachomatis or herpes simplex virus. Most HPV infections are cleared by the immune system and do not result in clinical complications. Clinical sequelae in cases of low-risk HPV infection consist of genital warts, and clinical manifestations of high-risk HPV infection include abnormal Pap test results, low-grade squamous intraepithelial lesions (LSIL, high-grade squamous intraepithelial lesions (HSIL, and cervical cancer. LSIL, HSIL, and cervical cancer carry significant morbidity and/or mortality; genital warts and abnormal Pap test results are often significant sources of psychosocial distress. Currently, there are neither effective means of preventing HPV transmission nor cures for clinical manifestations: infection can only be prevented via complete sexual abstinence, while treatment for clinical sequelae such as genital warts and cytologic abnormalities consists of removing the problematic cells and watching for recurrence; this method consumes significant health care resources and is costly. New prophylactic HPV vaccines promise to dramatically reduce the incidence of HPV infection, genital warts, and cytologic abnormalities.

    Squamous cell carcinoma (SCC) represents the most common genital malignant tumor in horses. Similar to humans, papillomaviruses (PVs) have been proposed as etiological agents and recently Equine papillomavirus type 2 (EcPV2) has been identified in a subset of genital SCCs. The goals of this study were (1) to determine the prevalence of EcPV2 DNA in tissue samples from equine genital SCCs, penile intraepithelial neoplasia (PIN) and penile papillomas, using EcPV2-specific PCR, (2) to examine the prevalence of latent EcPV2 infection in healthy genital mucosa and (3) to determine genetic variability within EcPV2 and to disentangle phylogenetic relationships of EcPV2 among PVs. EcPV2 DNA was detected in all but one penile SCC (15/16), in all PIN lesions (8/8) and penile papillomas (4/4). Additionally, EcPV2 DNA was demonstrated in one of two metastasized lymph nodes, one contact metastasis in the mouth, two vaginal and one anal lesion. In healthy horses, EcPV2 DNA was detected in 10% (4/39) of penile swabs but in none of vulvovaginal swabs (0/20). This study confirms the presence of EcPV2 DNA in equine genital SCCs and shows its involvement in anal lesions, a lymph node and contact metastases. Latent EcPV2 presence was also shown in normal male genital mucosa. We found that different EcPV2 variants cocirculate among horses and that EcPV2 is related to the Delta+Zeta PVs and is only a very distant relative of high-risk human PVs causing genital cancer. Thus, similar viral tropism and similar malignant outcome of the infection do not imply close evolutionary relationship. Copyright © 2012 Elsevier B.V. All rights reserved.

    Zika virus (ZIKV) is an arthropod-borne virus of the family Flaviviridae, genus Flavivirus. ZIKV is currently the focus of an ongoing pandemic and worldwide public health emergency. Although originally isolated in 1947, its pathogenesis was poorly known and very few documented infections were published until recently. Its route of transmission and its impact on reproduction and pregnancy have only recently begun to be disclosed. This review summarizes the most recent knowledge about ZIKV infection and pathogenesis and focuses on its impacts on male and female genital tracts, including the risks of sexual transmission and to pregnancy. The consequences of ZIKV infection for pregnancy planning and ART are also discussed. The PubMed and EMBASE databases were inter-rogated using specific terms, such as 'ZIKV', 'transmission', 'male', 'female', fertility', 'pregnancy, 'semen', 'testis', 'ovary' and 'genital tract', up to 17 March 2017. ZIKV has long been considered a harmless virus, but increasing evidence suggests that it has adverse effects on the neurological system and on pregnancy outcomes. In mice, ZIKV slows foetal growth and damages the foetal brain. In humans, the virus is able to cross the placental barrier and to induce foetal death and major anomalies, such as microcephaly, brain defects and long-term neurologic sequelae, i.e. the 'congenital Zika syndrome'. In addition to its transmission by mosquitoes, ZIKV may be transmitted sexually. Currently available data indicate that ZIKV RNA can remain detectable in semen for several months, whereas shedding in the female genital tract appears to be rare and of short duration. Current guidance on preventing the sexual transmission of ZIKV is based on the assumption that transmission occurs from a male partner to a receptive partner. Furthermore, in mouse models, the virus can actively replicate in male genital organs and induce severe orchitis, which raises concerns about its possible impact on human male fertility

    1994-01-01

    Full Text Available Objective: The involvement of the genital mycoplasmas Ureaplasma urealyticum and Mycoplasma hominis in complications of pregnancy has remained controversial especially because these microorganisms are frequent colonizers of the lower genital tract. Recovery of bacteria from the placenta appears to be the sole technique to represent a true infection and not vaginal contamination. Therefore, we investigated the presence of genital mycoplasmas, aerobic and anaerobic bacteria, and fungi in human placentas and evaluated their association with morbidity and mortality of pregnancy.

    2009-01-01

    Full Text Available Background. Although tuberculosis (TB is a major health problem worldwide, primary extrapulmonary tuberculosis (EPTB, and in particular female genital tract infection, remains a rare event. Case Report. A 35-year-old human immunodeficiency virus (HIV seropositive woman of African descent with lower abdominal pain and fever of two days duration underwent surgery due to left adnexal mass suggesting pelvic inflammatory disease. The surgical situs showed a four quadrant peritonitis, consistent with the clinical symptoms of the patient, provoked by a tuboovarian abscess (TOA on the left side. All routine diagnostic procedures failed to determine the causative organism/pathogen of the infection. Histopathological evaluation identified a necrotic granulomatous salpingitis and specific PCR analysis corroborated Mycobacterium tuberculosis (M. Tb. Consequently, antituberculotic therapy was provided. Conclusion. In the differential diagnosis of pelvic inflammatory disease, internal genital tuberculosis should be considered. Moreover, physicians should consider tuberculous infections early in the work-up of patients when immunosuppressive conditions are present.

    Genital warts are caused by human papillomavirus infection and represent one of the most common sexually transmitted diseases. Many infections are transient but the virus may recur, persist, or become latent. To date, there is no effective antiviral treatment to eliminate HPV infection and most therapies are aimed at the destruction of visible lesions. Potassium hydroxide is a strong alkali that has been shown to be safe and effective for the treatment of genital warts and molluscum contagiosum. Cryotherapy is considered one of the most established treatments for genital warts. No comparative trials have been reported to date on the use of potassium hydroxide for genital warts. A prospective, open-label, randomized clinical trial was conducted to compare topical potassium hydroxide versus cryotherapy in the treatment of genital warts affecting immunocompetent, sexually active men. Over a period of 10 months, 48 patients were enrolled. They were randomly divided into two groups and selected on an alternative basis for either potassium hydroxide therapy or cryotherapy. While response to therapy did not differ substantially between both treatment modalities, side effects such as local pain and post-treatment hypopigmentation were considerably more prevalent in the groups treated using cryotherapy. In our study, potassium hydroxide therapy proved to be at least as effective as cryotherapy and offered the benefit of a better safety profile. Topical 5% potassium hydroxide presents an effective, safe, and low-cost treatment modality for genital warts in men and should be included in the spectrum of therapies for genital warts.

    2012-02-01

    Herpes simplex virus (HSV)-2 is the predominant cause of genital herpes and has been implicated in HIV infection and transmission. Thus far, vaccines developed against HSV-2 have been clinically ineffective in preventing infection. This review aims to summarize the innate and adaptive immune responses against HSV-2 and examines the current status of vaccine development. Both innate and adaptive immune responses are essential for an effective primary immune response and the generation of immunity. The innate response involves Toll-like receptors, natural killer cells, plasmacytoid dendritic cells, and type I, II, and III interferons. The adaptive response requires a balance between CD4+ and CD8+ T-cells for optimal viral clearance. T-regulatory cells may be involved, although their exact function has yet to be determined. Current vaccine development involves the use of HSV-2 peptides or attenuated/replication-defective HSV-2 to generate adaptive anti-HSV-2 immune responses, however the generation of innate responses may also be an important consideration. Although vaccine development has primarily focused on the adaptive response, arguments for innate involvement are emerging. A greater understanding of the innate and adaptive processes underlying the response to HSV-2 infection will provide the foundation for the development of an effective vaccine.

    El virus de la rabia presenta un fuerte tropismo neuronal y que produce una encefalitis generalmente letal. En un accidente rábico clásico, producido por la mordedura de un animal infectado, el virus es captado por terminaciones nerviosas motoras, autonómicas o sensoriales. Si es captado por estas últimas, el virus se transporta retrógradamente hacia los somas neuronales ubicados en los ganglios espinales y de ahí pasa hasta el Sistema Nervioso Central en donde ejerce su acción patógena. Por este motivo los cultivos de ganglio espinal son un modelo relevante para estudiar la interacción entre el virus de la rabia y las neuronas sensoriales presentes en ellos. En estos cultivos se encuentran dos tipos de células, neuronas y células no neuronales (fibroblastos y células de Schwann. Al inocular los cultivos con virus de rabia cepa CVS (Challenge Virus Standard, a pesar de que las células no neuronales son la mayoría, las que se infectan en mayor proporción son las neuronas, lo que confirma el marcado neurotropismo del virus.

    Full Text Available Herpes simplex virus (HSV types 1 and 2 cause genital herpes infections and are the most common cause of genital ulcer disease in industrialized nations. Although these infections are very common, the majority of them remain underdiagnosed because they are asymptomatic or unrecognized. A clinical diagnosis of genital herpes should always be confirmed by laboratory testing; this can be accomplished through the use of direct tests for viral isolation, the detection of antigen or, more recently, the detection of HSV DNA using molecular diagnostic techniques. Testing for serotypes is recommended because of the different prognostic and counselling implications. Type-specific HSV serology is becoming more readily available and will enhance the ability to make the diagnosis and guide clinical management in select patients.

Here we review genes that are involved in various stages of female genital tract formation and development.

  2. Lactic acid alleviates stress: good for female genital tract homeostasis, bad for protection against malignancy.

    Women are unique from all other mammals in that lactic acid is present at high levels in the vagina during their reproductive years. This dominance may have evolved in response to the unique human lifestyle and a need to optimally protect pregnant women and their fetuses from endogenous and exogenous insults. Lactic acid in the female genital tract inactivates potentially pathogenic bacteria and viruses, maximizes survival of vaginal epithelial cells, and inhibits inflammation that may be damaging to the developing fetus and maintenance of the pregnancy. In an analogous manner, lactic acid production facilitates survival of malignantly transformed cells, inhibits activation of immune cells, and prevents the release of pro-inflammatory mediators in response to tumor-specific antigens. Thus, the same stress-reducing properties of lactic acid that promote lower genital tract health facilitate malignant transformation and progression.

    Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.

  5. Preventing HIV infection without targeting the virus: how reducing HIV target cells at the genital tract is a new approach to HIV prevention.

    2017-09-12

    For over three decades, HIV infection has had a tremendous impact on the lives of individuals and public health. Microbicides and vaccines studies have shown that immune activation at the genital tract is a risk factor for HIV infection. Furthermore, lower level of immune activation, or what we call immune quiescence, has been associated with a lower risk of HIV acquisition. This unique phenotype is observed in highly-exposed seronegative individuals from different populations including female sex workers from the Pumwani cohort in Nairobi, Kenya. Here, we review the link between immune activation and susceptibility to HIV infection. We also describe a new concept in prevention where, instead of targeting the virus, we modulate the host immune system to resist HIV infection. Mimicking the immune quiescence phenotype might become a new strategy in the toolbox of biomedical methods to prevent HIV infection. Clinical trial registration on clinicaltrial.gov: #NCT02079077.

    HIV resides within anatomical 'sanctuary sites', where local drug exposure and viral dynamics may differ significantly from the systemic compartment. Suboptimal antiretroviral concentrations in the genital tract may result in compartmentalized viral replication, selection of resistant mutations and possible re-entry of wild-type/resistant virus into the systemic circulation. Therefore, achieving adequate antiretroviral exposure in the genital tract has implications for the prevention of sexual and vertical transmission of HIV. Penetration of antiretrovirals in the genital tract is expressed by accumulation ratios derived from the measurement of drug concentrations in time-matched seminal plasma/cervicovaginal fluid and plasma samples. Penetration varies by gender and may be drug (as opposed to class) specific with high interindividual variability. Concentrations in seminal plasma are highest for nucleoside analogues and lowest for protease inhibitors and efavirenz. Seminal accumulation of newer agents, raltegravir and maraviroc, is moderate (rank order of accumulation is nucleoside/nucleotide reverse transcriptase inhibitors [lamivudine/zidovudine/tenofovir/didanosine > stavudine/abacavir] > raltegravir > indinavir/maraviroc/nevirapine > efavirenz/protease inhibitors [amprenavir/atazanavir/darunavir > lopinavir/ritonavir > saquinavir] > enfuvirtide). In the female genital tract, the nucleoside analogues exhibit high accumulation ratios, whereas protease inhibitors have limited penetration; however, substantial variability exists between individuals and study centres. Second generation non-nucleoside reverse transcriptase inhibitor etravirine, and maraviroc and raltegravir, demonstrate effective accumulation in cervicovaginal secretions (rank order of accumulation is nucleoside/nucleotide reverse transcriptase inhibitor [zidovudine/lamivudine/didanosine > emtricitabine/tenofovir] > indinavir > maraviroc/raltegravir/darunavir/etravirine > nevirapine

    Full Text Available Body piercing has been practiced for thousands of years all over the world for beautification, religion, initiation rites or status reasons. Genital piercings also have a significant background and have been practiced for enhancing sexual pleasure, chastity, shocking or as a protest against a conservative society. As the popularity of genital piercings increased in the last years, the number of complications is also on the rise. It is therefore important for the medical professionals to have at least basic knowledge regarding this practice, as it might be required in the management of unpredictable complications.

    Herpes simplex virus type 2 (HSV-2) is a prevalent infection with great variability in clinical and virological manifestations among individuals. This prospective cohort study aims to evaluate the natural history of HSV-2 reactivation in the genital area in the same group of women over time. Eighteen immunocompetent HSV-2 seropositive women were evaluated for viral shedding for 70 consecutive days within a median of 8 months (range 1-24 months) of HSV-2 acquisition and again approximately 2.5 years later from the original study. Participants obtained daily swabs of genital secretions for HSV PCR and recorded genital symptoms. The viral shedding rate was 29% during the initial study and 19% in the follow-up study (32% reduction, P=0.019). Subclinical shedding rate also decreased from 24% to 13% (37% reduction, P=0.032), as did the rate of days with genital lesions from 22% to 15% (33% reduction, P=0.24). The mean copy number during viral shedding remained unchanged over time at 4.8 log 10 c/mL (SD=2.0 and 1.6 during each study, respectively, P=0.33). Women with high viral shedding rates in the past were likely to continue to have high shedding rates (r=0.63, P=0.005). Despite some reduction, high viral shedding rates persist in women with genital HSV-2 greater than 2 years after acquisition. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Background: India accounts for one fifth of the global incidence of tuberculosis (TB annually. Genital tract TB is one of the extra pulmonary presentations of TB leading to infertility among Indian women. Genital TB is a chronic disease and often asymptomatic with very few specific complaints. Infertility is the most common clinical presentation of genital TB. Herein, we report a case of 32-year-old female patient suffering from abdominal pain and infertility for the last 8 months. Methods: Hysterosalpingography (HSG and ultrasonography (USG did not reveal characteristic radiological appearances of TB although USG detected the presence of a large fibroid in the right uterine wall. Histology, microscopy for acid fast bacilli, liquid culture and nucleic acid amplification assay targeting 64kDa protein encoding gene, the IS6110 element of endometrium biopsy were negative for tubercle bacilli. Results: Since the diagnosis of genital TB is elusive, antitubercular treatment (ATT using isoniazid, pyrazinamide, rifampicin, and ethambutol was prescribed for two months followed by maintenance therapy with isoniazid and rifampicin for four months without any pregnancy outcome. Conclusion: However, the patient conceived spontaneously after surgical removal of fibroid. Relating infertility to female genital tuberculosis due to high prevalence of TB in the country and ignoring the presence of uterine fibroid might not have been the right decision taken by the gynaecologist. This suggests the urgent need for an accurate method intended for diagnosis of female genital tuberculosis.

    The first UK prosecution for genital herpes simplex virus (HSV) transmission in 2011 attracted strong criticism from medical experts. To address the dearth of research on the topic, this study aimed to explore the nature of advice given to patients by the multidisciplinary team (MDT) in the West of Scotland on HSV disclosure to partners. Ten semi-structured interviews with members of the MDT were conducted and the interviews were analysed using Burnard's Thematic Content Analysis. Four themes emerged which explored practitioners' knowledge of HSV and their feelings regarding the emotional aspects of the diagnosis on clients including the challenges of discussing disclosure. Within this framework, participants' attitudes to the legal prosecution were also surveyed. This study revealed that participants had good knowledge about HSV. Furthermore, participants believed disclosure to be the patient's choice and had not altered their practice to advise disclosure to all partners in accordance with local protocol. However, there was a general consensus that disclosure was not required due to the prevalence of HSV and prevalence was used to dissipate emotional reactions to HSV diagnosis.

    Amenamevir is the international non-proprietary name for ASP2151 synthesized by Astellas Pharma, Inc. It is a structurally novel class of helicase-primase inhibitor and demonstrated more potency in vitro anti-viral activity with low cytotoxicity against varicella-zoster virus (VZV), herpes simplex virus type 1 (HSV-1), and herpes simplex virus type 2 (HSV-2) than acyclovir (ACV). Phase II randomized trial assessed the safety and efficacy of ASP2151 for episodic therapy of recurrent genital herpes was conducted. Participants self-initiated with ASP2151 (100, 200, or 400 mg daily for 3 days), ASP2151 (1,200 mg as a single dose), placebo for 3 days, or Valacyclovir (500 mg twice daily for 3 days). We present a first population pharmacokinetic (PPK) modeling analysis of Amenamevir for genital herpes patients. The final model retained the effect of Weight and Albumin on CL. Statistical analysis between pharmacokinetics and clinical efficacies was done by using the time above 200 ng/mL (T200 ). T200 derived from the final PPK model to consider the correlation with Time to lesion healing and viral shedding. This finding suggested that it could be necessary to maintain the Amenamevir concentration above the threshold level to prevent the virus replication. © 2014, The American College of Clinical Pharmacology.

    To examine the association between schistosomiasis and reproductive tract symptoms. A cross-sectional study was conducted in a Schistosoma haematobium-endemic area of rural Zimbabwe. A total of 483 permanently resident adult women of Mupfure Ward aged 20-49 were interviewed and examined clinically, each providing three consecutive urine samples. Logistic regression analysis was used to control for sexually transmitted diseases (STDs). Women with genital sandy patches had significantly more genital itch (P = 0.009) and perceived their discharge as abnormal (P = 0.003). Eighty percent of the women who had genital itch, yellow discharge, and childhood or current waterbody contact had sandy patches. Fifty-two percent of the women with genital sandy patches did not have detectable S. haematobium ova in urine. Genital schistosomiasis was associated with stress incontinence and pollakisuria, but not with menstrual irregularities, current or previous ulcers, or tumours. Genital schistosomiasis may be a differential diagnosis to the STDs in women who have been exposed to fresh water in endemic areas. Because of the chronic nature of the disease in adults, we suggest to pay special attention to the prevention of morbidity.

    HSV-1-based vectors have been widely used to achieve targeted delivery of genes into the nervous system. In the current study, we aim to use shRNA-containing HSV-1-based gene delivery system for the therapy of HSV-2 infection. Guinea pigs were infected intravaginally with HSV-2 and scored daily for 100 days for the severity of vaginal disease. HSV-2 shRNA-containing HSV-1 was applied intravaginally daily between 8 and 14 days after HSV-2 challenge. Delivery of HSV-2 shRNA-containing HSV-1 had no effect on the onset of disease and acute virus shedding in animals, but resulted in a significant reduction in both the cumulative recurrent lesion days and the number of days with recurrent disease. Around half of the animals in the HSV-2 shRNA group did not develop recurrent disease 100 days post HSV-2 infection. In conclusion, HSV-2 shRNA-containing HSV-1 particles are effective in reducing the recurrence of genital herpes caused by HSV-2. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Human papillomavirus (HPV is one of the most common sexually transmitted infections world-wide. Low-risk HPV-types are associated with genital warts. Persistent infection with high-risk HPV-types is associated with genital cancers. Smoking and HIV infection have consistently been associated with longer duration of HPV infection and risk for genital cancer. There is an increasing incidence of anal cancers, and a close association with HPV infection has been demonstrated. Receptive anal sex and HIV-positive status are associated with a high risk for anal cancer. Two HPV vaccines are now available and offer protection from infection by the HPV-types included in the vaccine. This benefit is maximally seen in young women who were uninfected prior to vaccination.

  19. Role of bovine herpesvirus type 5 (BoHV-5) in diseases of cattle. Recent findings on BoHV-5 association with genital disease

    Bovine herpesvirus type 5 (BoHV-5) belongs to the family Herpesviridae, subfamily Alphaherpesvirinae, genus Varicellovirus. This virus is a major causative agent of non-suppurative meningoencephalitis in young cattle. It was first isolated in 1962 from a neurological disease outbreak in Australia. BoHV-5 is genetically and antigenically related to bovine herpesvirus type 1 (BoHV-1), a highly prevalent virus responsible for respiratory and genital disease in cattle. Initially, BoHV-5 was considered a subtype of BoHV-1 (BoHV-1.3). However, the exclusive presentation of outbreaks of neurological disease suggested that the virus was a new agent with characteristics of neuropathogenicity. Even though both are neurotropic viruses, only BoHV-5 is capable of replicating extensively in the central nervous system and inducing neurological disease. Occasionally, encephalitis caused by BoHV-1 has been reported. Like other alpha-herpesviruses, BoHV-5 can establish latency in nervous ganglia and, by stress factors or glucocorticoid treatment, latent virus can be reactivated. During episodes of reactivation, the virus is excreted in nasal, ocular and genital secretions and transmitted to other susceptible hosts. Recently, BoHV-5 has been associated with infection of the reproductive tract. The virus has been isolated and the presence of viral DNA has been demonstrated in semen samples from Brazil and Australia and natural transmission of the virus through contaminated semen has also been described. Embryos and oocytes are permissive for BoHV-5 infection and BoHV-5 DNA has been detected in the central nervous system of aborted fetuses. The objective of this review is to compile the limited information on the recent association between BoHV-5 and reproductive disorders in cattle. PMID:26623291

    Herpes simplex virus type 2 (HSV-2) reactivation is accompanied by a sustained influx of CD4(+) and CD8(+) T cells that persist in genital tissue for extended periods. While CD4(+) T cells have long been recognized as being present in herpetic ulcerations, their role in subclinical reactivation and persistence is less well known, especially the role of CD4(+) regulatory T cells (Tregs). We characterized the Treg (CD4(+)Foxp3(+)) population during human HSV-2 reactivation in situ in sequential genital skin biopsy specimens obtained from HSV-2-seropositive subjects at the time of lesion onset up to 8 weeks after healing. High numbers of Tregs infiltrated to the site of viral reactivation and persisted in proximity to conventional CD4(+) T cells (Tconvs) and CD8(+) T cells. Treg density peaked during the lesion stage of the reactivation. The number of Tregs from all time points (lesion, healed, 2 weeks after healing, 4 weeks after healing, and 8 weeks after healing) was significantly higher than in control biopsy specimens from unaffected skin. There was a direct correlation between HSV-2 titer and Treg density. The association of a high Treg to Tconv ratio with high viral shedding suggests that the balance between regulatory and effector T cells influences human HSV-2 disease. © The Author 2016.

    The dynamics of genital shedding of HSV-2 DNA was assessed in HIV-1-infected women taking combination antiretroviral therapy (cART). HIV-1 RNA, HIV-1 DNA and HSV DNA loads were measured during 12-18 months using frozen plasma, PBMC and cervicovaginal lavage samples from 22 HIV-1-infected women, including 17 women naive for antiretroviral therapy initiating cART and 5 women with virological failure switching to a new regimen. Nineteen (86%) women were HSV-2-seropositive. Among HSV-2-/HIV-1-co-infected women, HIV-1 RNA loads showed a rapid fall from baseline after one month of cART, in parallel in paired plasma and cervicovaginal secretions. In contrast, HIV-1 DNA loads did not show significant variations from baseline up to 18 months of treatment in both systemic and genital compartments. HSV DNA was detected at least once in 12 (63%) of 19 women during follow up: HSV-2 shedding in the genital compartment was observed in 11% of cervicovaginal samples at baseline and in 16% after initiating or switching cART. Cervicovaginal HIV-1 RNA loads were strongly associated with plasma HIV-1 RNA loads over time, but not with cervicovaginal HSV DNA loads. Reactivation of genital HSV-2 replication frequently occurred despite effective cART in HSV-2-/HIV-1-co-infected women. Genital HSV-2 replication under cART does not influence cervicovaginal HIV-1 RNA or DNA shedding. © The Author(s) 2015.

    Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art [3] and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood [6]. In somatosensory cortex specifically, many studies did not detect any cortical representation of genitals [7-9]. Studies in humans debate whether genitals are represented displaced below the foot of the cortical body map [10-12] or whether they are represented somatotopically [13-15]. We wondered what a high-resolution mapping of genital representations might tell us about the sexual differentiation of the mammalian brain. We identified genital responses in rat somatosensory cortex in a region previously assigned as arm/leg cortex. Genital responses were more common in males than in females. Despite such response dimorphism, we observed a stunning anatomical monomorphism of cortical penis and clitoris input maps revealed by cytochrome-oxidase-staining of cortical layer 4. Genital representations were somatotopic and bilaterally symmetric, and their relative size increased markedly during puberty. Size, shape, and erect posture give the cortical penis representation a phallic appearance pointing to a role in sexually aroused states. Cortical genital neurons showed unusual multi-body-part responses and sexually dimorphic receptive fields. Specifically, genital neurons were co-activated by distant body regions, which are touched during mounting in the respective sex. Genital maps indicate a deep homology of penis and clitoris representations in line with a fundamentally bi-sexual layout [16] of the vertebrate brain. Copyright © 2016 Elsevier Ltd.

    Herpes Simplex Virus Type 2 (HSV-2) infection can result in life-long recurrent genital disease, asymptomatic virus shedding, and transmission. No vaccine to date has shown significant protection clinically. Here, we used a mouse model of genital HSV-2 infection to test the efficacy of a vaccine consisting of whole, formalin-inactivated HSV-2 (FI-HSV2) formulated with monophosphoryl lipid A (MPL) and alum adjuvants. Vaccine components were administered alone or as a prime-boost immunization together with DNA vaccines encoding a truncated glycoprotein D2 (gD2t) and two conserved HSV-2 genes necessary for virus replication, UL5 (DNA helicase) and UL30 (DNA polymerase). Our results show: (1) compared with mock immunized controls, mice immunized with FI-HSV2 plus MPL/alum consistently showed protection against disease burden and total viral shedding while the mice immunized with gD2t protein with MPL/alum did not; (2) protection against genital disease and viral replication correlated with the type of boost in a prime-boost immunization with little advantage afforded by a DNA prime; (3) intramuscular (i.m.) immunization with FI-HSV2 in MPL/Alhydrogel adjuvant provided nearly complete protection against vaginal HSV-2 shedding after a lethal intravaginal (i.vag.) short-term challenge and long-term rechallenge; (4) single formulation immunization with DNA vaccines, FI-HSV2, and MPL in an aluminum phosphate (Adju-Phos) adjuvant did not increase protection relative to FI-HSV2/MPL/Adju-Phos alone; and (5) addition of MPL/alum to the FI-HSV2 was required for optimal protection against disease, viral replication, and latent virus load in the dorsal root ganglia (DRG). Most notably, an optimized vaccine formulation of FI-HSV2 MPL/Alhydrogel given i.m. completely protected against detectable vaginal HSV-2 shedding in the majority of animals and HSV-2 latent DNA in the DRG of all animals.

    To compare the prevalence of abnormal anal cytology and high-risk human papillomavirus (HPV) among women with a history of HPV-related genital neoplasia with women without a history of HPV-related genital neoplasia. A cross-sectional cohort study was performed from December 2012 to February 2014. Women were recruited from outpatient clinics at an academic medical center. Women with a history of high-grade cervical, vulvar, or vaginal cytology, dysplasia, or cancer were considered the high-risk group. Women with no history of high-grade anogenital dysplasia or cancer were considered the low-risk group. Human immunodeficiency virus-positive women were excluded. Anal cytology and HPV genotyping were performed. Women with abnormal anal cytology were referred for high-resolution anoscopy. There were 190 women in the high-risk group and 83 in the low-risk group. The high-risk group was slightly older: 57 years compared with 47 years (P=.045); 21.7% of low-risk women had abnormal anal cytology compared with 41.2% of high-risk women (P=.006). High-risk HPV was detected in the anal canal of 1.2% of the low-risk group compared with 20.8% of the high-risk group (PHuman immunodeficiency virus-negative women with a history of lower genital tract neoplasia are more likely to have positive anal cytology, anal high-risk HPV, and anal intraepithelial neoplasia. Anal cancer screening should be considered for these high-risk women. II.

    Targeting of the mucosal immune system of the genital tract with subunit vaccines has failed to induce potent and durable local CD8(+) T cell immunity, which is crucial for protection against many sexually transmitted viral pathogens, including HSV type 2 (HSV-2), which causes genital herpes. In this study, we aimed to investigate the potential of a novel lipopeptide/adenovirus type 5 (Lipo/rAdv5) prime/boost mucosal vaccine for induction of CD8(+) T cell immunity to protect the female genital tract from herpes. The lipopeptide vaccine and the rAdv5 vaccine express the immunodominant HSV-2 CD8(+) T cell epitope (gB(498-505)), and both were delivered intravaginally in the progesterone-induced B6 mouse model of genital herpes. Compared with mice immunized with the homologous lipopeptide/lipopeptide (Lipo/Lipo) vaccine, the Lipo/rAdv5 prime/boost immunized mice 1) developed potent and sustained HSV-specific CD8(+) T cells, detected in both the genital tract draining nodes and in the vaginal mucosa; 2) had significantly lower virus titers; 3) had decreased overt signs of genital herpes disease; and 4) did not succumb to lethal infection (p herpes infection and disease.

    An important question in the study of chlamydial genital tract disease is why some women develop severe upper tract disease while others have mild or even "silent" infections with or without pathology. Animal studies suggest that the pathological outcome of an infection is dependent upon both the composition of the infecting chlamydial population and the genotype of the host, along with host physiological effects, such as the cyclical production of reproductive hormones and even the size of the infecting inoculum or the number of repeated infections. In this study, we compared two variants of Chlamydia caviae, contrasting in virulence, with respect to their abilities to ascend the guinea pig genital tract. We then determined the effect of combining the two variants on the course of infection and on the bacterial loads of the two variants in the genital tract. Although the variants individually had similar infection kinetics in the cervix, SP6, the virulent variant, could be isolated from the oviducts more often and in greater numbers than the attenuated variant, AZ2. SP6 also elicited higher levels of interleukin 8 (IL-8) in the lower genital tract and increased leukocyte infiltration in the cervix and uterus compared to AZ2. When the two variants were combined in a mixed infection, SP6 outcompeted AZ2 in the lower genital tract; however, AZ2 was able to ascend the genital tract as readily as SP6. These data suggest that the ability of SP6 to elicit an inflammatory response in the lower genital tract facilitates the spread of both variants to the oviducts.

    Full Text Available RESUMEN La determinación por parte de la Organización Mundial de la Salud de que el brote de enfermedad por el virus del Ébola constituía un evento de salud pública de importancia internacional llevó a los países que no estaban afectados a aplicar medidas para prevenir y detectar la introducción del virus en sus territorios y para reaccionar frente a ella. El brote brindó la oportunidad de evaluar la aplicación operativa de las capacidades básicas del Reglamento Sanitario Internacional y la preparación de los sistemas de salud para hacer frente a un caso posible o confirmado de enfermedad por el virus del Ébola. Un marco rector de salud pública aplicado en los países de América Latina y el Caribe, que abarca autoevaluaciones preparatorias, visitas a los propios países y seguimiento, sugiere que esa región debe aumentar sus esfuerzos por consolidar y mantener los progresos en las capacidades básicas y en la preparación del sistema de salud para hacer frente a eventos de salud pública que tengan repercusiones a escala nacional o internacional.

    A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

    ABSTRACT A number of men receiving prolonged suppressive highly active antiretroviral therapy (HAART) still shed human immunodeficiency virus (HIV) in semen. To investigate whether this seminal shedding may be due to poor drug penetration and/or viral production by long-lived cells within male genital tissues, we analyzed semen and reproductive tissues from macaques chronically infected with simian immunodeficiency virus mac251 (SIVmac251) who were treated for 4 months with HAART, which was intensified over the last 7 weeks with an integrase inhibitor. We showed that a subset of treated animals continued shedding SIV in semen despite efficient HAART. This shedding was not associated with low antiretroviral drug concentrations in semen or in testis, epididymis, seminal vesicles, and prostate. HAART had no significant impact on SIV RNA in the urethra, whereas it drastically reduced SIV RNA levels in the prostate and vas deferens and to a lesser extent in the epididymis and seminal vesicle. The only detectable SIV RNA-positive cells within the male genital tract after HAART were urethral macrophages. SIV DNA levels in genital tissues were not decreased by HAART, suggesting the presence throughout the male genital tract of nonproductively infected cells. In conclusion, our results demonstrate that 4 months of HAART induced variable and limited control of viral infection in the male reproductive organs, particularly in the urethra, and suggest that infected long-lived cells in the male genital tract may be involved in persistent seminal shedding during HAART. These results pave the way for further investigations of male genital organ infection in long-term-treated infected individuals. IMPORTANCE A substantial subset of men receiving prolonged HAART suppressing viral loads in the blood still harbor HIV in semen, and cases of sexual transmission have been reported. To understand the origin of this persistence, we analyzed the semen and male reproductive tissues from SIV

    Introduction: Cervical cancer probably represents the best-studied human cancer caused by a viral infection and the causal association of this preventable cancer with human papilloma virus (HPV) is well established. Worldwide there is a scarcity of data regarding HPV prevalence with vast differences existing among populations. Objective: The aim of this meta-analysis was to determine the community-based HPV prevalence estimates among asymptomatic women from urban and rural set ups and in participants of cancer screening clinics. Study design: Systematic review and meta-analysis. Methods: PubMed-Medline, CINAHL, Scopus, and Google scholar were systematically searched for studies providing prevalence data for HPV infection among asymptomatic women between 1986 and 2016. Results: The final analysis included 32 studies comprising a population of 224,320 asymptomatic women. The overall pooled HPV prevalence was 11% (95% confidence interval (CI), 9%-12%). The pooled HPV prevalence of 11% (95% CI, 9%-11%) was observed among women attending cervical cancer screening clinics. The pooled HPV prevalences were 10% (95% CI 8%-12%) and 11% (95% CI 4%-18%) from urban and rural areas respectively, indicating higher infection rates among the rural women with the least access to cancer screening and cancer care. Conclusion: The prevalence rates in this systematic quantitative review provide a reliable estimate of the burden of HPV infection among asymptomatic women from developed as well as developing nations. Rural women and women attending cervical cancer screening programmes feature higher genital HPV prevalences compared to their urban counterparts. Creative Commons Attribution License

    Full Text Available El virus de la Lengua azul (VLA es un ARN virus de doble cadena que induce apoptosis tanto en cultivos celulares como en tejidos blanco. Con el fin de dilucidar el mecanismo de apoptosis en la infección por el VLA, en el presente trabajo examinamos en detalle, por la técnica de Western blot, las señales celulares de caspasas, Bax, citocromo c, Smac/DIABLO y factor nuclear kappa B (NF-kB que se activan en la infección viral. Hemos comprobado que luego de la infección in vitro con el VLA, se detectó la activación de la caspasa 8 y con ello el mecanismo extrínseco de la apoptosis. También detectamos por primera vez no sólo la activación de miembros de la familia Bcl-2 (Bax, sino también la liberación del citocromo c y la proteína Smac/DIABLO, confirmando que en la infección por el VLA está involucrado el mecanismo secuencial intrínseco de la apoptosis. Asimismo, demostramos que la infección por el VLA activa el NF-kB y que la apoptosis es sustancialmente reducida mediante la inhibición del mismo. La activación de las señales celulares tales como Bax, citocromo c, Smac/DIABLO y NF-kB presentados en este trabajo, esclarecen los mecanismos apoptóticos durante la infección por el VLA para una mayor comprensión del papel primario que juega la apoptosis en la patogénesis del virus.Bluetongue (BTV is a double-stranded RNA virus that induces apoptosis both in mammalian cell cultures and in target tissues.

    Full Text Available The assumed importance of genital surgery for intersex children as well as the rising popularity of cosmetic surgery for one’s genitals (namely for women exemplify the importance placed on gender distinction in Western culture. This paper will explore how these genital surgeries are tied to the idealized conception of the gender binary that exists in our culture. Despite the reality that genitals, especially the vulva, vary widely in appearance (size, shape, colour, the belief that there are norms of genital appearance that need to be adhered to continues to be propagated within Western culture. I will posit that genital surgeries in the West are a culturally imbued practice. This will be argued in light of Leti Volpp’s assertion that people in the West need to recognize how our own culture promotes patriarchal/normative practices that can be dangerous and degrading to individuals. For instance, Western discourse vilifies cultures that engage in female genital mutilation (FGM without realizing how Western culture itself pressures women to ‘mutilate’ their genitals through cosmetic surgery or intersex surgery. The cultural influence of the West must be acknowledged so that we can better perceive how the agency of Western subjects is also directed and confined by our cultural context. Western culture also acts upon its subjects and, in this case, pushes gender binaries and the ideal of the perfect ‘normal’ vagina. This paper will utilize queer theory to question the necessity of gender binaries and to reveal the way that binary gender is privileged in our society. L'importance majeure de la chirurgie génitale pour les enfants intersexués ainsi que la popularité croissante de la chirurgie esthétique pour les organes génitaux, particulièrement pour les femmes, illustrent l'importance accordée à la distinction entre les sexes dans la culture occidentale.

    Full Text Available Introduction: Surgery for bladder exstrophy has been evolving over the last four to five decades. Because survival has become almost universal, the focus has changed in the exstrophy-epispadias complex to improving quality of life. The most prevalent problem in the long-term function of exstrophy patients is the sexual activity of the adolescent and adult males. The penis in exstrophy patients appears short because of marked congenital deficiency of anterior corporal tissue. Many patients approach for genital reconstruction to improve cosmesis as well as to correct chordee. We report our series of male patients seeking genital reconstruction following exstrophy repair in the past. Materials and Methods: Fourteen adolescent/adult male patients attended urology services during the period January 2000-December 2009 seeking genital reconstruction following exstrophy repair in the past. Results: Three patients underwent epispadias repair, four patients had chordee correction with cosmetic excision of skin tags and seven patients underwent chordee correction with penile lengthening. All patients reported satisfaction in the answered questionnaire. Patients undergoing penile lengthening by partial corporal dissection achieved a mean increase in length of 1.614 ± 0.279 cm dorsally and 1.543 ± 0.230 cm ventrally. The satisfactory rate assessed by the Short Form-36 (SF-36 showed that irrespective of the different genital reconstructive procedures done, the patients were satisfied with cosmetic and functional outcome. Conclusions: Surgical procedures have transformed the management in these patients with bladder exstrophy. Bladders can be safely placed within the pelvis, with most patients achieving urinary continence and cosmetically acceptable external genitalia. Genital reconstruction in the form of correction of chordee, excision of ugly skin tags and lengthening of penis can be performed to give the patients a satisfactory cosmetic and functional

    Full Text Available Los pacientes con infección por el virus de inmunodeficiencia humana (HIV tienen una mayor prevalencia de disfunción tiroidea cuando se los compara con la población general. Las manifestaciones más frecuentemente observadas son: el síndrome del eutiroideo enfermo, la enfermedad de Graves y el hipotiroidismo subclínico. La relación entre el uso de la terapia antirretroviral y el incremento en la prevalencia de alteraciones tiroideas fue demostrada en varias series de pacientes. La enfermedad de Graves se reconoce claramente como una consecuencia del síndrome de restitución inmune. Además, existen estudios que sugieren una relación entre hipotiroidismo y el uso de inhibidores nucleósidos de la transcriptasa reversa, en particular estavudina y el inhibidor no nucleósido de la transcriptasa reversa efavirenz. Nuevos estudios podrán aportar evidencia adicional sobre la necesidad de evaluaciones rutinarias de la función tiroidea en pacientes infectados por HIV.

They had a history of recurrent oral ulcers as well. All patients had been diagnosed as having ′genital ulcer syndrome′ in the past and had been treated with antimicrobials. Histopathology of the biopsy from the margin of the ulcer revealed features of leukocytoclastic vasculitis. Considering the history, clinical features and histology, a diagnosis of bipolar aphthosis was made in all patients. All patients responded well to immunosuppressive therapy. The cases are reported because of the presence of genital ulcers of an unusually large size, mutilating character and their close similarity to genital ulcers due to sexually transmitted diseases, especially genital herpes and donovanosis.

  10. Rapid host immune response and viral dynamics in herpes simplex virus-2 infection

    Schiffer, Joshua T; Corey, Lawrence

    2014-01-01

    Herpes Simplex Virus-2 (HSV-2) is episodically shed throughout the human genital tract. While high viral load correlates with development of genital ulcers, shedding also commonly occurs even when ulcers are not present, allowing for silent transmission during coitus and contributing to high seroprevalence of HSV-2 worldwide. Frequent viral reactivation occurs despite diverse and complementary host and viral mechanisms within ganglionic tissue that predispose towards latency, suggesting that viral replication may be constantly occurring in a small minority of neurons within the ganglia. Within genital mucosa, the in vivo expansion and clearance rates of HSV-2 are extremely rapid. Resident dendritic cells and memory HSV-specific T cells persist at prior sites of genital tract reactivation, and in conjunction with prompt innate recognition of infected cells, lead to rapid containment of infected cells. Shedding episodes vary greatly in duration and severity within a single person over time: this heterogeneity appears best explained by variation in the densities of host immunity across the genital tract. The fact that immune responses usually control viral replication in genital skin prior to development of lesions provides optimism that enhancing such responses could lead to effective vaccines and immunotherapies.

    Findings regarding the link between body image and sexuality have been equivocal, possibly because of the insensitivity of many of body image measures to potential variability across sensory aspects of the body (e.g., appearance versus odor), individual body parts (e.g., genitalia versus thighs), and social settings (e.g., public versus intimate). The current study refined existing methods of evaluating women's body image in the context of sexuality by focusing upon two highly specified dimensions: satisfaction with the visual appearance of the genitalia and self-consciousness about the genitalia during a sexual encounter. Genital appearance dissatisfaction, genital image self-consciousness, and multiple facets of sexuality were examined with a sample of 217 undergraduate women using an online survey. Path analysis revealed that greater dissatisfaction with genital appearance was associated with higher genital image self-consciousness during physical intimacy, which, in turn, was associated with lower sexual esteem, sexual satisfaction, and motivation to avoid risky sexual behavior. These findings underscore the detrimental impact of negative genital perceptions on young women's sexual wellbeing, which is of particular concern given their vulnerability at this stage of sexual development as well as the high rates of sexually transmitted infections within this age group. Interventions that enhance satisfaction with the natural appearance of their genitalia could facilitate the development of a healthy sexual self-concept and provide long-term benefits in terms of sexual safety and satisfaction.

However, the concordance between the perception of vulvar and vaginal sensation (ie, somatic and visceral genital sensations, respectively) remains unstudied in healthy women, as well as in clinical populations such as PVD. To evaluate the static and dynamic (time-varying) properties of somatic and visceral genital sensation, women with PVD (n=14) and age- and contraceptive-matched healthy controls (n=10) rated varying degrees of nonpainful and painful genital stimulation. Somatic (vulvar) mechanical sensitivity to nonpainul and painful degrees of force were compared to visceral (vaginal) sensitivity to nonpainful and painful distension volumes. Results indicated that healthy women showed substantial individual variation in and high discrimination of vulvar and vaginal sensation. In contrast, PVD was associated with vulvar allodynia and hyperalgesia, as well as vaginal allodynia. Modeling of dynamic perception revealed novel properties of abnormal PVD genital sensation, including temporal delays in vulvar touch perception and reduced perceptual thresholds for vaginal distension. The temporal properties and magnitude of PVD distension pain were indistinguishable from vaginal fullness in healthy controls. These results constitute the first empirical comparison of somatic and visceral genital sensation in healthy women. Findings provide novel insights into the sensory abnormalities that characterize PVD, including an experimental demonstration of visceral allodynia. This investigation challenges the prevailing diagnostic assessment of PVD and reconceptualizes PVD as a chronic somatic and visceral pain condition. Copyright © 2013. Published by Elsevier B.V.

    Genital elephantiasis is a disease that is characterized by massive enlargement of the genitalia. Early aetiological diagnosis is of paramount importance so that development of genital elephantiasis can be prevented; otherwise it is not completely reversible with medical therapy and often requires surgical intervention. Chronic mental distress and disability can result as it interferes with daily/routine activities of the affected individual. Over time, the infectious causes of genital elephantiasis have evolved, from syphilis in the pre-penicillin era to donovanosis, lymphogranuloma venereum and recently filariasis, tuberculosis, leishmaniasis, HIV and chromoblastomycosis. With a declining prevalence globally, donovanosis is at risk of being forgotten as a cause of genital swelling; however, it is known to persist for years without treatment and can lead to complications such as lymphoedema and genital mutilation. We herein present a case of genital elephantiasis that was eventually diagnosed as being due to donovanosis.

    General and subjective information about those who chose to obtain genital piercings was presented. Particularly, the assumptions made from the literature are refuted by objective and subjective data collected from intimately pierced individuals themselves. Professional nurses must not base practice decisions on assumptions but on the "best evidence with clinical experience, research, (as well as) associated patient values" (Sackett, Strauss, Richardson, Rosenberg, & Haynes, 2001, p. 10). Thus, providing clinically competent care is driven by the latest knowledge and evidence from research and patient sources. Data found here provide further empirical evidence that may help to improve client outcomes by advancing evidence-based nursing practice in relation to people with genital piercings.

    Bovine herpes virus 1 (BHV-1) is primarily associated with clinical syndromes such as rhinotracheitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, conjunctivitis and encephalitis in bovine species. The main sources of infection are the nasal exudates and the respiratory droplets, genital secretions, semen, fetal fluids and tissues. The BHV-1 virus can become latent following a primary infection with a field isolate or vaccination with an attenuated strain. The viral genomic DNA has been demonstrated in the sensory ganglia of the trigeminal nerve in infectious bovine rhinotracheitis (IBR) and in sacral spinal ganglia in pustular vulvovaginitis and balanoposthitis cases. BHV-1 infections can be diagnosed by detection of virus or virus components and antibody by serological tests or by detection of genomic DNA by polymerase chain reaction (PCR), nucleic acid hybridization and sequencing. Inactivated vaccines and modified live virus vaccines are used for prevention of BHV-1 infections in cattle; subunit vaccines and marker vaccines are under investigation.

    Head and neck squamous cell carcinoma and especially oropharyngeal squamous cell carcinoma is a very significant cause of morbidity and mortality. The majors risk factors of these tumors are tobacco smoking, chewing and alcohol consumption. But there is a group, non-drinking and non-smoking, patients with oropharyngeal squamous cell carcinoma. In these patients may be oral-genital contact and human papillomavirus infection the major risk factor for oral carcinogenesis. Aim of this review is to point out this fact in correlation with clinical studies and clinical conclusion for medical practice (Fig. 1, Ref. 32).

    Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD)--syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum; and other non-STD disorders (NSTD)--Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53). Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. The etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied.

    Full Text Available Rat somatosensory cortex contains a large sexually monomorphic genital representation. Genital cortex undergoes an unusual 2-fold expansion during puberty. Here, we investigate genital cortex development and female rat sexual maturation. Ovariectomies and estradiol injections suggested sex hormones cause the pubertal genital cortex expansion but not its maintenance at adult size. Genital cortex expanded by thalamic afferents invading surrounding dysgranular cortex. Genital touch was a dominant factor driving female sexual maturation. Raising female rats in contact with adult males promoted genital cortex expansion, whereas contact to adult females or nontactile (audio-visual-olfactory male cues did not. Genital touch imposed by human experimenters powerfully advanced female genital cortex development and sexual maturation. Long-term blocking of genital cortex by tetrodotoxin in pubescent females housed with males prevented genital cortex expansion and decelerated vaginal opening. Sex hormones, sexual experience, and neural activity shape genital cortex, which contributes to the puberty promoting effects of sexual touch.

    Myelin oligodendrocyte glycoprotein (MOG) antibody-positive optic neuritis (ON) and myelitis are recognized as important differential diagnosis of aquaporin-4 (AQP4) antibody-positive neuromyelitis optica (NMO)/NMO spectrum disorder (NMOSD). Similar to NMO/NMOSD associated with AQP4 antibodies, preceding infections have been reported in patients with MOG antibody-positive ON. This is the first report of bilateral ON following a herpes simplex virus (HSV) infection associated with a positive MOG antibody. A 41-year-old man who initially presented with genital herpes developed allodynia in the Th2-Th5 and Th8-L2 areas, urinary retention, and painful visual loss in the left eye. Ophthalmological evaluation and brain magnetic resonance imaging (MRI) revealed bilateral ON. A spinal MRI showed leptomeningeal enhancement from the thoracic to lumbar vertebrae and abnormal enhancement of the L3 to S3 dorsal root ganglia without a change in intramedullary signals. Following treatment with acyclovir and steroid pulse, he fully recovered. Serum anti-AQP4 antibodies were negative, but anti-MOG antibodies were positive. Finally, he was diagnosed with MOG antibody-positive bilateral ON and meningoganglionitis following an HSV infection. Our case supports a relationship between anti-MOG antibodies and ON triggered by an HSV infection. Clinicians should thus consider testing for MOG antibodies in patients with post-infectious neurological symptoms due to an HSV infection. Copyright © 2017 Elsevier B.V. All rights reserved.

    Topical microbicides are a leading strategy for prevention of HIV mucosal infection to women; however, numerous pharmacokinetic limitations associated with coitally related dosing strategy have contributed to their limited success. Here we test the hypothesis that adeno-associated virus (AAV) mediated delivery of the b12 human anti-HIV-1 gp120 minibody gene to the lower genital tract of female rhesus macaques (Rh) can provide prolonged expression of b12 minibodies in the cervical-vaginal secretions. Gene transfer studies demonstrated that, of various green fluorescent protein (GFP)-expressing AAV serotypes, AAV-6 most efficiently transduced freshly immortalized and primary genital epithelial cells (PGECs) of female Rh in vitro. In addition, AAV-6-b12 minibody transduction of Rh PGECs led to inhibition of SHIV162p4 transmigration and virus infectivity in vitro. AAV-6-GFP could also successfully transduce vaginal epithelial cells of Rh when applied intravaginally, including p63+ epithelial stem cells. Moreover, intravaginal application of AAV-6-b12 to female Rh resulted in prolonged minibody detection in their vaginal secretions throughout the 79-day study period. These data provide proof of principle that AAV-6-mediated delivery of anti-HIV broadly neutralizing antibody (BnAb) genes to the lower genital tract of female Rh results in persistent minibody detection for several months. This strategy offers promise that an anti-HIV-1 genetic microbicide strategy may be possible in which topical application of AAV vector, with periodic reapplication as needed, may provide sustained local BnAb expression and protection.

    Genital herpes caused by herpes simplex virus type 2 (HSV-2) remains the leading cause of genital ulcers worldwide. Given the disappointing results of the recent genital herpes vaccine trials in humans, development of novel vaccine strategies capable of eliciting protective mucosal and systemic immune responses to HSV-2 is urgently required. Here we tested the ability of the adjuvant IC31(®) in combination with HSV-2 glycoprotein D (gD) used through intranasal (i.n.), intradermal (i.d.), or subcutaneous (s.c.) immunization routes for induction of protective immunity against genital herpes infection in C57BL/6 mice. Immunization with gD plus IC31(®) through all three routes of immunization developed elevated gD-specific serum antibody responses with HSV-2 neutralizing activity. Whereas the skin routes promoted the induction of a mixed IgG2c/IgG1 isotype profile, the i.n. route only elicited IgG1 antibodies. All immunization routes were able to induce gD-specific IgG antibody responses in the vaginas of mice immunized with IC31(®)-adjuvanted gD. Although specific lymphoproliferative responses were observed in splenocytes from mice of most groups vaccinated with IC31(®)-adjuvanted gD, only i.d. immunization resulted in a significant splenic IFN-γ response. Further, immunization with gD plus IC31(®) conferred 80-100% protection against an otherwise lethal vaginal HSV-2 challenge with amelioration of viral replication and disease severity in the vagina. These results warrant further exploration of IC31(®) for induction of protective immunity against genital herpes and other sexually transmitted infections. Copyright © 2012 Elsevier Ltd.

    Combination antiretroviral therapy (cART) reduces genital tract human immunodeficiency virus type 1 (HIV-1) load and reduces the risk of sexual transmission, but little is known about the efficacy of cART for decreasing genital tract viral load (GTVL) and differences in sex or HIV-1 subtype. HIV-1 RNA from blood plasma, seminal plasma, or cervical wicks was quantified at baseline and at weeks 48 and 96 after entry in a randomized clinical trial of 3 cART regimens. One hundred fifty-eight men and 170 women from 7 countries were studied (men: 55% subtype B and 45% subtype C; women: 24% subtype B and 76% subtype C). Despite similar baseline CD4(+) cell counts and blood plasma viral loads, women with subtype C had the highest GTVL (median, 5.1 log10 copies/mL) compared to women with subtype B and men with subtype C or B (4.0, 4.0, and 3.8 log10 copies/mL, respectively; P female genital tract may serve as a reservoir of persistent HIV-1 replication during cART and affect the use of cART to prevent sexual and perinatal transmission of HIV-1.

    Genital elephantiasis is an important medical problem in the tropics. It usually affects young and productive age group, and is associated with physical disability and extreme mental anguish. The majority of cases are due to filariasis; however, a small but significant proportion of patients develop genital elephantiasis due to bacterial sexually transmitted infections (STIs), mainly lymphogranuloma venereum (LGV) and donovanosis. STI-related genital elephantiasis should be differentiated from elephantiasis due to other causes, including filariasis, tuberculosis, haematological malignancies, iatrogenic, or dermatological diseases. Laboratory investigations like microscopy of tissue smear and nucleic acid amplification test for donovanosis, and serology and polymerase chain reaction for LGV may help in the diagnosis, but in endemic areas, in the absence of laboratory facilities, diagnosis largely depends on clinical characteristics. The causative agent of LGV, Chlamydia trachomatis serovar L1-L3, is a lymphotropic organism which leads to the development of thrombolymphangitis and perilymphangitis, and lymphadenitis. Long-standing oedema, fibrosis and lymphogranulomatous infiltration result in the final picture of elephantiasis. Elephantiasis in donovanosis is mainly due to constriction of the lymphatics which are trapped in the chronic granulomatous inflammatory response generated by the causative agent, Calymmatobacterium (Klebsiella) granulomatis. The LGV-associated genital elephantiasis should be treated with a prolonged course of doxycycline given orally, while donovanosis should be treated with azithromycin or trimethoprim-sulphamethoxazole combination given for a minimum of three weeks. Genital elephantiasis is not completely reversible with medical therapy alone and often needs to be reduced surgically.

    Full Text Available La nefropatia por polyoma virus (NVBK esta siendo reconocida como causa importante de falla del injerto, usualmente confundido con rechazo agudo. A la fecha, no se han reportado casos en el Perú. Se presenta el caso de un niño trasplantado, 17 años de edad, quien presentó elevación persistente de la creatinina sérica en el primer mes postrasplante. Fue tratado como rechazo agudo. Al no presentar mejoría se realizó biopsia renal que mostró marcado daño del epitelio tubular con necrosis parcial y desprendimiento hacia la luz tubular y la presencia de células atípicas con escaso citoplasma e inclusiones intranucleares basofilicas, hallazgos compatibles con infección por virus BK. No se evidenció signos de rechazo. Además, en el papanicolao de orina, se encontró Decoy cells. La carga viral de virus BK fue elevada en sangre y en orina. Se suspendió el tratamiento con mofetil micofenolato, se redujo la dosis de tacrolimus y se inició el tratamiento con leflunomide 40 mg/dia. Seis meses después la función renal del paciente se estabilizó, pero sin mejoría completa quedando con una depuración de creatinina de 30 ml/min/1,73 m² SC. (Rev Med Hered 2008;19:123-127

    Full Text Available El poliomavirus humano BK causa infección primaria asintomática en la niñez, estableciendo latencia principalmente en el tracto urinario. En individuos con alteración en la inmunidad celular se puede producir su reactivación desencadenando patología a nivel renal. Por estas razones es particularmente importante en la población pediátrica trasplantada renal, en la que puede producir la infección primaria cuando el paciente está inmunosuprimido. En nuestro trabajo se realizó el seguimiento de un paciente de 5 años trasplantado renal en octubre de 2003 que 45 días post-trasplante sufrió un deterioro del órgano injertado. Desde la fecha del trasplante hasta junio de 2004 se produjeron 3 episodios de alteración en la función renal, durante los cuales se analizaron muestras de sangre, orina, biopsia renal y líquido de linfocele. Para el diagnóstico difererencial entre rechazo agudo versus causa infecciosa se emplearon técnicas de detección para los virus BK, CMV y ADV, además del estudio citológico del tejido renal. Los resultados obtenidos junto con la clínica del paciente indican un probable caso de infección por BK. La importancia de realizar el diagnóstico diferencial entre rechazo agudo y la infección por BK radica en que la conducta en cuanto a la terapia inmunosupresora es opuesta en cada caso.BK Human Polyomavirus causes an asymptomatic primary infection in children, then establishing latency mainly in the urinary tract. Viral reactivation can lead to renal pathology in individuals with impaired cellular immune response. This is particularly important in pediatric transplant recipients, who can suffer a primary infection when immunosupressed. We followed up the case of a 5 years old patient who received a renal transplant in October 2003, and presented damaged graft 45 days after the intervention.

    Full Text Available The mucosal surface of the female genital tract is a complex biosystem, which provides a barrier against the outside world and participates in both innate and acquired immune defense systems. This mucosal compartment has adapted to a dynamic, non-sterile environment challenged by a variety of antigenic/inflammatory stimuli associated with sexual intercourse and endogenous vaginal microbiota. Rapid innate immune defenses against microbial infection usually involve the recognition of invading pathogens by specific pattern-recognition receptors recently attributed to the family of Toll-like receptors (TLRs. TLRs recognize conserved pathogen-associated molecular patterns (PAMPs synthesized by microorganisms including bacteria, fungi, parasites, and viruses as well as endogenous ligands associated with cell damage. Members of the TLR family, which includes 10 human TLRs identified to date, recognize distinct PAMPs produced by various bacterial, fungal, and viral pathogens. The available literature regarding the innate immune system of the female genital tract during human reproductive processes was reviewed in order to identify studies specifically related to the expression and function of TLRs under normal as well as pathological conditions. Increased understanding of these molecules may provide insight into site-specific immunoregulatory mechanisms in the female reproductive tract.

    Full Text Available Genital tuberculosis is a kind of infectious diseases with a relatively high prevalence in developing countries. The aim of this study was to investigate the prevalence of genital tuberculosis among infertile women. A PubMed, Science Direct, Scopus, Google Scholar, SID, Magiran and Cochrane databases (from 1980 to the present, date of last search March 2016 was carried out using the search keywords tuberculosis, genital tuberculosis, female genital, genital tract, genital system, female infertility, endometrial tuberculosis, anti-tubercular therapy, bacteriological, tuberculin antigen, histological, infertility, fallopian tube diseases, prevalence, rate, percent in order to find the studies which have reported the prevalence of genital tuberculosis among infertile women. Data were extracted from retrieved studies and a meta-analysis was done. 23 studies were found. In these studies a total of 4361 infertile women have been studied. The prevalence of genital tuberculosis among infertile women with 95% confidence interval was 24.2% (18.5-29.99. The prevalence of genital tuberculosis among infertile women is high. It seems that exact planning and action for the prevention and treatment of genital tuberculosis can reduce the infertility prevalence and prevent the negative consequences of infertility

    Full Text Available Female genital mutilation (FGM, sometimes referred to as female circumcision or female genital cutting, is a harmful cultural practice without any known health benefit. Its short-term and long-term health risks have led to numerous initiatives toward its eradication at international and local levels, over the last two decades. While major challenges remain and millions of girls and women are still at risk of being subjected to FGM, there is growing evidence that interventions that take into account the social dynamics that perpetuate FGM are yielding positive results toward its reduction. Well-recognized as a human rights violation in international treaties, the elimination of female genital mutilation requires ongoing interventions through cross-sectoral approaches that address attitudinal, cultural and behavioral change.

  7. Herpes Simplex Vaccines: Prospects of Live-attenuated HSV Vaccines to Combat Genital and Ocular infections

    Science.gov (United States)

    Stanfield, Brent; Kousoulas, Konstantin Gus

    2015-01-01

    Herpes simplex virus type-1 (HSV-1) and its closely related type-2 (HSV-2) viruses cause important clinical manifestations in humans including acute ocular disease and genital infections. These viruses establish latency in the trigeminal ganglionic and dorsal root neurons, respectively. Both viruses are widespread among humans and can frequently reactivate from latency causing disease. Currently, there are no vaccines available against herpes simplex viral infections. However, a number of promising vaccine approaches are being explored in pre-clinical investigations with few progressing to early phase clinical trials. Consensus research findings suggest that robust humoral and cellular immune responses may partially control the frequency of reactivation episodes and reduce clinical symptoms. Live-attenuated viral vaccines have long been considered as a viable option for generating robust and protective immune responses against viral pathogens. Varicella zoster virus (VZV) belongs to the same alphaherpesvirus subfamily with herpes simplex viruses. A live-attenuated VZV vaccine has been extensively used in a prophylactic and therapeutic approach to combat primary and recurrent VZV infection indicating that a similar vaccine approach may be feasible for HSVs. In this review, we summarize pre-clinical approaches to HSV vaccine development and current efforts to test certain vaccine approaches in human clinical trials. Also, we discuss the potential advantages of using a safe, live-attenuated HSV-1 vaccine strain to protect against both HSV-1 and HSV-2 infections. PMID:27114893

  10. Mathematical Modeling Predicts that Increased HSV-2 Shedding in HIV-1 Infected Persons Is Due to Poor Immunologic Control in Ganglia and Genital Mucosa.

    Directory of Open Access Journals (Sweden)

    Joshua T Schiffer

    Full Text Available A signature feature of HIV infection is poor control of herpes virus infections, which reactivate from latency and cause opportunistic infections. While the general mechanism underlying this observation is deficient CD4+T-cell function, it is unknown whether increased severity of herpes virus infections is due primarily to poor immune control in latent or lytic sites of infection, or whether CD4+ immunodeficiency leads to more critical downstream deficits in humoral or cell-mediated immunologic responses. Here we compare genital shedding patterns of herpes simplex virus-2 (HSV-2 in 98 HIV infected and 98 HIV uninfected men matched on length of infection, HSV-1 serostatus and nationality. We demonstrate that high copy HSV-2 shedding is more frequent in HIV positive men, particularly in participants with CD4+ T-cell count <200/μL. Genital shedding is more frequent due to higher rate of shedding episodes, as well as a higher proportion of prolonged shedding episodes. Peak episode viral load was not found to differ between HIV infected and uninfected participants regardless of CD4+ T-cell count. We simulate a mathematical model which recapitulates these findings and identifies that rate of HSV-2 release from neural tissue increases, duration of mucosal cytolytic immune protection decreases, and cell-free viral lifespan increases in HIV infected participants. These results suggest that increased HSV-2 shedding in HIV infected persons may be caused by impaired immune function in both latent and lytic tissue compartments, with deficits in clearance of HSV-2 infected cells and extracellular virus.

    Objective We assessed the protective effect of medical male circumcision (MMC) against HIV, herpes simplex virus type 2 (HSV-2), and genital ulcer disease (GUD) incidence. Design Two thousand, seven hundred and eighty-seven men aged 18–24 years living in Kisumu, Kenya were randomly assigned to circumcision (n=1391) or delayed circumcision (n =1393) and assessed by HIV and HSV-2 testing and medical examinations during follow-ups at 1, 3, 6, 12, 18, and 24 months. Methods Cox regression estimated the risk ratio of each outcome (incident HIV, GUD, HSV-2) for circumcision status and multivariable models estimated HIV risk associated with HSV-2, GUD, and circumcision status as time-varying covariates. Results HIV incidence was 1.42 per 100 person-years. Circumcision was 62% protective against HIV [risk ratio =0.38; 95% confidence interval (CI) 0.22–0.67] and did not change when controlling for HSV-2 and GUD (risk ratio =0.39; 95% CI 0.23–0.69). GUD incidence was halved among circumcised men (risk ratio =0.52; 95% CI 0.37–0.73). HSV-2 incidence did not differ by circumcision status (risk ratio =0.94; 95% CI 0.70–1.25). In the multivariable model, HIV seroconversions were tripled (risk ratio =3.44; 95% CI 1.52–7.80) among men with incident HSV-2 and seven times greater (risk ratio =6.98; 95% CI 3.50–13.9) for men with GUD. Conclusion Contrary to findings from the South African and Ugandan trials, the protective effect of MMC against HIV was independent of GUD and HSV-2, and MMC had no effect on HSV-2 incidence. Determining the causes of GUD is necessary to reduce associated HIV risk and to understand how circumcision confers protection against GUD and HIV PMID:22382150

    We evaluated a genital herpes prophylactic vaccine containing herpes simplex virus 2 (HSV-2) glycoproteins C (gC2) and D (gD2) to stimulate humoral immunity and UL19 (capsid protein VP5) and UL47 (tegument protein VP13/14) as T cell immunogens. The HSV-2 gC2 and gD2 proteins were expressed in baculovirus, while the UL19 and UL47 genes were expressed from replication-defective adenovirus vectors. Adenovirus vectors containing UL19 and UL47 stimulated human and murine CD4(+) and CD8(+) T cell responses. Guinea pigs were either (i) mock immunized; (ii) immunized with gC2/gD2, with CpG and alum as adjuvants; (iii) immunized with the UL19/UL47 adenovirus vectors; or (iv) immunized with the combination of gC2/gD2-CpG/alum and the UL19/UL47 adenovirus vectors. Immunization with gC2/gD2 produced potent neutralizing antibodies, while UL19 and UL47 also stimulated antibody responses. After intravaginal HSV-2 challenge, the mock and UL19/UL47 adenovirus groups developed severe acute disease, while 2/8 animals in the gC2/gD2-only group and none in the combined group developed acute disease. No animals in the gC2/gD2 or combined group developed recurrent disease; however, 5/8 animals in each group had subclinical shedding of HSV-2 DNA, on 15/168 days for the gC2/gD2 group and 13/168 days for the combined group. Lumbosacral dorsal root ganglia were positive for HSV-2 DNA and latency-associated transcripts for 5/8 animals in the gC2/gD2 group and 2/8 animals in the combined group. None of the differences comparing the gC2/gD2-only group and the combined group were statistically significant. Therefore, adding the T cell immunogens UL19 and UL47 to the gC2/gD2 vaccine did not significantly reduce genital disease and vaginal HSV-2 DNA shedding compared with the excellent protection provided by gC2/gD2 in the guinea pig model. HSV-2 infection is a common cause of genital ulcer disease and a significant public health concern. Genital herpes increases the risk of transmission and

    Plastic surgery relies on photography for both clinical practice and research. The Photographic Standards in Plastic Surgery laid the foundation for standardized photography in plastic surgery. Despite these advancements, the current literature lacks guidelines for genital photography, thus resulting in a discordance of documentation. The authors propose photographic standards for the male and female genitalia to establish homogeneity in which information can be accurately exchanged. All medical photographs include a sky-blue background, proper lighting, removal of distractors, consistent camera framing, and standard camera angles. We propose the following guidelines to standardize genital photography. In the anterior upright position, feet are shoulder-width apart and arms are placed posteriorly. The frame is bounded superiorly by the xiphoid-umbilicus midpoint and inferiorly by the patella. For circumferential documentation, frontal 180 degree capture via 45 degree intervals is often sufficient. Images in standard lithotomy position should be captured at both parallel and 45 degrees above the horizontal. Images of the phallus should include both the flaccid and erect states. Despite the increasing incidence of genital procedures, there lacks a standardized methodology in which to document the genitalia, resulting in a substantial heterogeneity in the current literature. Our standardized techniques for genital photography set forth to establish a uniform language that promotes more effective communication with both the patient as well as with colleagues. The proposed photography guidelines provide optimal visualization and standard documentation of the genitalia, allowing for accurate education, meaningful collaborations, and advancement in genital surgery. © 2018 The American Society for Aesthetic Plastic Surgery, Inc.

    Genital human papilloma virus infection (HPV) is the most common sexually transmitted infection worldwide, it is the cause of genital warts, and it is related with cervical cancer, the second most common cause of death from cancer in women in America, and the first in underdeveloped countries, and it is related with penis and prostate cancer in males also, and with anal cancer in both genders. This review examines the most important actual facts about HPV infection, and the new prophylactic vaccines. Two versions of the vaccine had been developed, both target HPV 16 and HPV 18, which involve approximately 70% of cervical cancer. One of them also targets HPV 6 and HPV 11, which account for approximately 90% of external genital warts. Both vaccines have an excellent safety profile, are highly immunogenic, and have atributed complete type specific protection against persistent infection and associated lesions in fully vaccinated girls and young women. The role of men as carriers of HPV as well as vectors for transmission is well documented. Several clinical trials are currently under way to determine the efficacy of vaccinating men. Reducing the cost of vaccination would be a priority for the developing world in order to get a broad target in poor countries.

    Full Text Available Female genital mutilation has been drawing international attention for the last couple of decades, but this phenomenon is almost unknown in Serbia. In this work we will point to its basic forms and its presence in the world as well as to the variety of consequences, especially those which are the most common causes of death. With this purpose in mind, the work represents the a review of theoretical debates and empirical studies, based on which relevant data may be gathered, related to the previously mentioned subject of the work. Female genital mutilation is a phenomenon mostly in Africa, but due to migrations has become a problem thoughout the whole world. Traditional and cultural norms of strict patriarchal societies along with deeply rooted inequality of genders have contributed to the maintenance of this custom up till today. This custom includes a sequence of different procedures which are used to injure female genitals even though there are no medical reasons for such acts. They are conducted by older women in insanitary conditions and by means such as scissors, razors or glass which bring numerous consequences which can result in death. Females subdued to infibulation are at greater risk of death, although each of the forms of mutilation may have this consequence. Female genital mutilation represents violence against women due to its inevitable physical consequences and its harmful effect on health. Girls and women are subdued to the procedure which in some cases results in death, for the purpose of the community acceptance, most of all the acceptance of the future husband. Namely, women are elligible for marriage only if they are virgins, which is achieved by genital mutilation, according to the opinion of the community in which this tradition is preserved. Beside that, marriage is of high importance for the economic stability of a woman, considering the fact that all the economic power is held by men. Genital mutilation has the purpose

    Plasma HIV RNA is the most significant determinant of cervical HIV shedding. However, shedding is also associated with sexually transmitted infections (STIs) and cervical inflammation. The mechanism by which this occurs is poorly understood. There is evidence that systemic immune activation promotes viral entry, replication, and HIV disease progression. We hypothesized that systemic immune activation would be associated with an increase in HIV genital shedding. Clinical assessments, HIV RNA in plasma and genital secretions, and markers of immune activation (CD38(+)DR(+) and CD38(-)DR(-)) on CD4(+) and CD8(+) T cells in blood were evaluated in 226 HIV+ women enrolled in the Women's Interagency HIV Study. There were 569 genital evaluations of which 159 (28%) exhibited HIV RNA shedding, defined as HIV viral load >80 copies per milliliter. We tested associations between immune activation and shedding using generalized estimating equations with logit link function. In the univariate model, higher levels of CD4(+) and CD8(+) T-cell activation in blood were significantly associated with genital tract shedding. However, in the multivariate model adjusting for plasma HIV RNA, STIs, and genital tract infections, only higher levels of resting CD8(+) T cells (CD38(-)DR(-)) were significantly inversely associated with HIV shedding in the genital tract (odds ratios = 0.44, 95% confidence interval: 0.21 to 0.9, P = 0.02). The association of systemic immune activation with genital HIV shedding is multifactorial. Systemic T-cell activation is associated with genital tract shedding in univariate analysis but not when adjusting for plasma HIV RNA, STIs, and genital tract infections. In addition, women with high percentage of resting T cells are less likely to have HIV shedding compared with those with lower percentages. These findings suggest that a higher percentage of resting cells, as a result of maximal viral suppression with treatment, may decrease local genital activation, HIV

    Full Text Available La infección por Mycobacterium tuberculosis ha sido siempre una causa importante de morbilidad y mortalidad en los países tropicales. Se ha dicho que en un país tropical de escasos recursos el riesgo de adquirir tuberculosis (TBC, cada año, a partir del nacimiento es de 1 a 2.5%, de esta manera se puede suponer que la mayoría de los adultos tienen una enfermedad silente que se podría activar. La prevalencia de la TBC del tracto genital femenino (TGF va paralela a la de la TBC pulmonar y generalmente la diseminación hacia éste, es hematógena a partir de un foco pulmonar. Llama la atención la gran frecuencia con la que se ve la TBC del TGF en los países en vías de desarrollo y aun cuando en nuestro hospital han sido pocos los casos que se han visto de TBC en esta localización,  onsideramos es importante tenerla en cuenta en pacientes que estén en estudio por infertilidad e incluso en pacientes que presenten masa pélvicas anexiales.

    Protection from naturally acquired human papillomavirus (HPV) antibodies may influence HPV infection across the lifespan. This study describes seroconversion rates following genital, anal, and oral HPV 6/11/16/18 infections in men and examines differences by HPV type and anatomic site. Men with HPV 6/11/16/18 infections who were seronegative for those genotypes at the time of DNA detection were selected from the HPV Infection in Men (HIM) Study. Sera specimens collected ≤36 months after detection were analyzed for HPV 6/11/16/18 antibodies using a virus-like particle-based ELISA. Time to seroconversion was separately assessed for each anatomic site, stratified by HPV type. Seroconversion to ≥1 HPV type (6/11/16/18) in this sub-cohort (N=384) varied by anatomic site, with 6.3, 18.9, and 0.0% seroconverting following anal, genital, and oral HPV infection, respectively. Regardless of anatomic site, seroconversion was highest for HPV 6 (19.3%). Overall, seroconversion was highest following anal HPV 6 infection (69.2%). HPV persistence was the only factor found to influence seroconversion. Low seroconversion rates following HPV infection leave men susceptible to recurrent infections that can progress to HPV-related cancers. This emphasizes the need for HPV vaccination in men to ensure immune protection against new HPV infections and subsequent disease.

    Topical or systemic antiviral drugs reduce the duration of genital herpes recurrences but may not always alleviate functional symptoms. To assess the efficacy and safety of oxygenated glycerol triesters-based CS21 barrier genital gel(®) vs. topical aciclovir and placebo (vehicle) in resolving functional symptoms and in healing of genital herpes recurrences. A prospective randomized controlled, investigator-blinded trial of CS21 barrier genital gel(®) vs. topical aciclovir (reference treatment) and placebo (vehicle) was designed. The primary endpoint was the cumulative score of four herpes-related functional symptoms (pain, burning, itching and tingling sensations). Secondary endpoints included objective skin changes (erythema, papules, vesicles, oedema, erosion/ulceration, crusts), time to heal, local tolerance and overall acceptability of the treatment as reported by a self-administered questionnaire. Overall, 61 patients were included. CS 21 barrier genital gel(®) was significantly more efficient than topical aciclovir and vehicle for subjective symptoms and pain relief in genital herpes recurrences; additionally, time to heal was significantly shorter with CS 21 than with vehicle, whereas no significantly difference was observed between patients receiving topical aciclovir and vehicle. The treatments under investigation were well tolerated and the adverse events were comparable in the three treatment groups. Overall, these results support the interest of using of CS 21 barrier genital gel(®) in symptomatic genital herpes recurrences. Accordingly, this product offers a valuable alternative in topical management of recurrent genital herpes. © 2013 European Academy of Dermatology and Venereology.

    Full Text Available Herpes simplex virus type 1 (HSV-1 commonly causes orolabial ulcers, while HSV-2 commonly causes genital ulcers. However, HSV-1 is an increasing cause of genital infection. Previously, the World Health Organization estimated the global burden of HSV-2 for 2003 and for 2012. The global burden of HSV-1 has not been estimated.We fitted a constant-incidence model to pooled HSV-1 prevalence data from literature searches for 6 World Health Organization regions and used 2012 population data to derive global numbers of 0-49-year-olds with prevalent and incident HSV-1 infection. To estimate genital HSV-1, we applied values for the proportion of incident infections that are genital.We estimated that 3709 million people (range: 3440-3878 million aged 0-49 years had prevalent HSV-1 infection in 2012 (67%, with highest prevalence in Africa, South-East Asia and Western Pacific. Assuming 50% of incident infections among 15-49-year-olds are genital, an estimated 140 million (range: 67-212 million people had prevalent genital HSV-1 infection, most of which occurred in the Americas, Europe and Western Pacific.The global burden of HSV-1 infection is huge. Genital HSV-1 burden can be substantial but varies widely by region. Future control efforts, including development of HSV vaccines, should consider the epidemiology of HSV-1 in addition to HSV-2, and especially the relative contribution of HSV-1 to genital infection.

    Background: Human papilloma virus (HPV) is a virus that causes genital warts and a range of different cancer types. Vaccination against HPV was introduced in Norway in 2009, for girls in the 7th grade, as a part of the Norwegian Childhood Vaccination Program. There has been much discussion about the HPV-vaccine before and after the vaccine introduction. The uptake of HPV-vaccination is lower (67-75%) than for other vaccines. The lower vaccine uptake may be explained by lack of information abo...

  8. Sex differences in patterns of genital sexual arousal: measurement artifacts or true phenomena?

    2009-08-01

    Sex differences in patterns of sexual arousal have been reported recently. Men's genital arousal is typically more category-specific than women's, such that men experience their greatest genital arousal to stimuli depicting their preferred sex partners whereas women experience significant genital arousal to stimuli depicting both their preferred and non-preferred sex partners. In addition, men's genital and subjective sexual arousal patterns are more concordant than women's: The correlation between genital and subjective sexual arousal is much larger in men than in women. These sex differences could be due to low response-specificity in the measurement of genital arousal in women. The most commonly used measure of female sexual arousal, vaginal photoplethysmography, has not been fully validated and may not measure sexual arousal specifically. A total of 20 men and 20 women were presented with various sexual and non-sexual emotionally laden short film clips while their genital and subjective sexual arousal were measured. Results suggest that vaginal photoplethysmography is a measure of sexual arousal exclusively. Women's genital responses were highest during sexual stimuli and absent during all non-sexual stimuli. Sex differences in degree of category-specificity and concordance were replicated: Men's genital responses were more category-specific than women's and men's genital and subjective sexual arousal were more strongly correlated than women's. The results from the current study support the continued use of vaginal photoplethysmography in investigating sex differences in patterns of sexual arousal.

    Genital herpes is incurable, and is caused by the herpes simplex virus (HSV). First-episode genital herpes is the first clinical presentation of herpes that a person experiences. Current treatment is based around viral suppression in order to decrease the length and severity of the episode. To determine the effectiveness and safety of the different existing treatments for first-episode genital herpes on the duration of symptoms and time to recurrence. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (from inception to April 2016), MEDLINE (from inception to April 2016), the Specialised Register of the Cochrane Sexually Transmitted Infections Review Group (from inception to April 2016), EMBASE (from inception to April 2016), PsycINFO (from inception to April 2016), CINAHL (from inception to April 2016), LILACS (from inception to April 2016), AMED (from inception to April 2016), and the Alternative Medicines Specialised Register (from inception to April 2016). We handsearched a number of relevant journals, searched reference lists of all included studies, databases of ongoing trials, and other Internet databases. We included randomised controlled trials (RCTs) on participants with first-episode genital herpes. We excluded vaccination trials, and trials in which the primary objective assessed a complication of HSV infection. All studies written in English were independently assessed by at least two review authors for inclusion, risk of bias for each trial, and to extract data. Studies requiring translation were assessed for inclusion, trial quality, and data extraction by external translators. We included 26 trials with 2084 participants analysed. Most of the studies were conducted in the United Kingdom (UK) and United States (US), and involved men and women experiencing their first episode of genital herpes, with the exception of three studies which included only women. We rated the majority of these studies as having an unclear risk of bias

    The genetic heterogeneity of melanomas and melanocytic nevi of the female genital tract is poorly understood. We aim to characterize the frequency of mutations of the following genes: BRAF, NRAS, KIT, GNA11, and GNAQ in female genital tract melanomas. We also characterize the frequency of BRAF mutations in female genital tract melanomas compared with melanocytic nevi. Mutational screening was performed on the following female genital tract melanocytic neoplasms: 25 melanomas, 7 benign melanocytic nevi, and 4 atypical melanocytic nevi. Of the 25 female genital tract melanoma specimens queried, KIT mutations were detected in 4 (16.0%), NRAS mutations in 4 (16.0%), and BRAF mutations in 2 (8.0%) samples. Two of the tumors with KIT mutations harbored double mutations in the same exon. No GNAQ or GNA11 mutations were identified among 11 melanomas screened. BRAF V600E mutations were detected in 7 of 7 benign melanocytic genital nevi (100%) and 3 of 4 atypical genital nevi (75%). Our study is limited by the small sample size of this rare subset of melanomas. KIT, NRAS, and BRAF mutations are found in a subset of female genital tract melanomas. Screening for oncogenic mutations is important for developing and applying clinical therapies for melanomas of the female genital tract. Copyright © 2014 American Academy of Dermatology, Inc.

    Purpose: To report the success of groin nodal lymphography in the diagnosis and treatment of genital lymphedema. Methods and Materials: We present one female (8 years old [patient no. 1]) and two male (69 and [patient no. 2] 31 years old [patient no. 3], respectively) patients with genital lymphedema in whom conservative treatment failed. The girl also had lymphorrhagia. Genital lymphedema was caused by radical cystectomy (patient no. 2), lymphatic hyperplasia (patient no. 1), and idiopathic lymphangitis (patient no. 3). All of them underwent ultrasound-guided bilateral groin lymph node puncture. Afterward, 4-8 ml Lipiodol Ultra-Fluide (Guerbet) were injected at a rate of 0.2 ml/s. Lipiodol progression was assessed by fluoroscopy. Computed tomography scan of the abdomen and pelvis was performed immediately after and again at 24 h after the procedure to confirm the leak. The follow-up period was 15, 13, and 9 months, respectively. Technical success was considered as bilateral pelvic and abdominal filling of lymphatic vessels. Therapeutic success was considered as improvement or disappearance of genital lymphedema and/or lymphorrhagia. Results: Lipiodol leak to the scrotum was observed in patients no. 2 and 3. Lymphaticopelvic fistula and genital lymphatic hyperplasia were seen in patient no. 1. Genital lymphedema diminished within 1 week and almost disappeared in two cases (patients no. 1 and 3) or significantly improved (patient no. 2). lymphorrhagia also resolved in patient no. 1. No recurrence or worsening was detected during follow-up. Conclusion: Therapeutic lymphangiography by lymph node injection seems to be effective to treat genital lymphedema. Lymph node puncture lymphangiography is feasible and less cumbersome than pedal lymphangiography.

    To examine the risks of genital herpes and antiherpes treatment during pregnancy in relation to preterm delivery (PTD), we conducted a multicenter, member-based cohort study within 4 Kaiser Permanente regions: northern and southern California, Colorado, and Georgia. The study included 662,913 mother-newborn pairs from 1997 to 2010. Pregnant women were classified into 3 groups based on genital herpes diagnosis and treatment: genital herpes without treatment, genital herpes with antiherpes treatment, and no herpes diagnosis or treatment (unexposed controls). After controlling for potential confounders, we found that compared with being unexposed, having untreated genital herpes during first or second trimester was associated with more than double the risk of PTD (odds ratio (OR) = 2.23, 95% confidence interval (CI): 1.80, 2.76). The association was stronger for PTD due to premature rupture of membrane (OR = 3.57, 95% CI: 2.53, 5.06) and for early PTD (≤35 weeks gestation) (OR = 2.87, 95% CI: 2.22, 3.71). In contrast, undergoing antiherpes treatment during pregnancy was associated with a lower risk of PTD compared with not being treated, and the PTD risk was similar to that observed in the unexposed controls (OR = 1.11, 95% CI: 0.89, 1.38). The present study revealed increased risk of PTD associated with genital herpes infection if left untreated and a potential benefit of antiherpes medications in mitigating the effect of genital herpes infection on the risk of PTD. © The Author 2014.

  1. Epidemiological impact of a genital herpes type 2 vaccine for young females.

    Directory of Open Access Journals (Sweden)

    Yijun Lou

    Full Text Available Genital Herpes, which is caused by Herpes Simplex Virus-1 or -2 (HSV-1, -2, predominantly HSV-2 is a sexually transmitted infection (STI that causes a chronic latent infection with outbreak episodes linked to transmission. Antiviral therapies are effective in reducing viral shedding during these episodes, but are ineffective as a whole since many outbreaks are asymptomatic or have mild symptoms. Thus, the development of a vaccine for genital herpes is needed to control this disease. The question of how to implement such a vaccine program is an important one, and may be similar to the vaccination program for Human Papilloma Virus (HPV for young females. We have developed a mathematical model to describe the epidemiology of vaccination targeting young females against HSV-2. The model population is delineated with respect to age group, sexual activity and infection status including oral infection of HSV-1, which may affect vaccine efficacy. A threshold parameter R(C, which determines the level of vaccine uptake needed to eradicate HSV-2, is found. Computer simulation shows that an adolescent-only vaccination program may be effective in eliminating HSV-2 disease, however, the success of extinction greatly depends on the level of vaccine uptake, the vaccine efficacy, the age of sexual maturity and safe sex practices. However, the time course of eradication would take many years. We also investigate the prevalence of infection in the total population and in women between 16-30 years of age before and after vaccination has been introduced, and show that the adolescent-only vaccination program can be effective in reducing disease prevalence in these populations depending on the level of vaccine uptake and vaccine efficacy. This will also result in a decrease of maternal-fetal transmission of HSV-2 infection. Another important, if commonsense, conclusion is that vaccination of some females reduces infection in men, which then reduces infection in women.

    Full Text Available Abstract Background Caprine herpesvirus 1 (CpHV-1 is responsible of systemic diseases in kids and genital diseases leading to abortions in goats. CpHV-1 is widespread and especially in Mediterranean countries as Greece, Italy and Spain. CpHV-1 is antigenically and genetically closely related to bovine herpesvirus 1 (BoHV-1. Taking into account the biological properties shared by these two viruses, we decided in the current study to assess the protection of a live attenuated glycoprotein E (gE negative BoHV-1 vaccine against a genital CpHV-1 infection in goats. Results The vaccine was inoculated intranasally twice three weeks apart followed by a subsequent CpHV-1 intravaginal challenge which is the natural route of infection in three goats. To analyse the safety and the efficacy of this marker vaccine, two groups of three goats served as controls: one immunised with a virulent CpHV-1 and one uninoculated until the challenge. Goats were clinically monitored and all sampling procedures were carried out in a blind manner. The vaccine did not induce any undesirable local or systemic reaction and goats did not excrete gE-negative BoHV-1. After challenge, a significant reduction in disease severity was observed in immunised goats. Moreover, goats immunised with either gE-negative BoHV-1 or CpHV-1 exhibited a significant reduction in the length and the peak of viral excretion. Antibodies neutralising both BoHV-1 and CpHV-1 were raised in immunised goats. Conclusion Intranasal application of a live attenuated gE-negative BoHV-1 vaccine is able to afford a clinical protection and a reduction of virus excretion in goats challenged by a CpHV-1 genital infection.

    Female genital tuberculosis (TB) remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome (AIDS). Genital TB is commonly asymptomatic, and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools, such as computerized tomography (CT) scan, magnetic reson...

    Full Text Available The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

    Many women have doubts about the normality of the physical appearance of their vulvas. This study measured genital self-image in a convenience sample of college-educated women, and assessed whether exposure to pictures of natural vulvas influenced their genital self-image. Forty-three women were either shown pictures of natural vulvas (N = 29) or pictures of neutral objects (N = 14). Genital self-image was measured before and after exposure to the pictures and two weeks later. Sexual function, sexual distress, self-esteem and trait anxiety were measured to investigate whether these factors influenced genital self-image scores after vulva picture exposure. A majority of the participants felt generally positively about their genitals. Having been exposed to pictures of natural vulvas resulted in an even more positive genital self-image, irrespective of levels of sexual function, sexual distress, self-esteem and trait anxiety. In the women who had seen the vulva pictures, the positive effect on genital self-image was still present after two weeks. The results of this study seem to indicate that even in young women with a relatively positive genital self-image, exposure to pictures of a large variety of natural vulvas positively affects genital self-image. This finding may suggest that exposure to pictures of natural vulvas may also lead to a more positive genital self-image in women who consider labiaplasty.

    Although atypical presentations of herpetic infection in immunocompetent individuals are common, they very rarely have the extensive, chronic and verrucous appearances seen in the immunocompromised host. We report a case of genital herpes manifesting as painless chronic non-healing genital ulcers with exuberant granulation tissue in an immunocompetent man. Owing to this morphology, the ulcers were initially mistaken for donovanosis. To the best of our knowledge, such a presentation of genital herpes in an immunocompetent individual has not been described previously. © The Author(s) 2015.

    Full Text Available En todas partes del mundo han surgido epidemias de enfermedades transmitidas por los alimentos (ETA sobre las que no existe suficiente información para guiar las acciones de las instituciones de salud pública. El presente estudio se hizo con objeto de contribuir a la diseminación de información sobre esas enfermedades, sus agentes etiológicos y su epidemiología y control. Se utilizaron datos de 61 estudios, entre ellos revisiones, descripciones de brotes y sistematización de datos. De los resultados obtenidos se pudo concluir que hay un gran problema de subregistro y falta de datos sobre estas enfermedades en los diversos países, pero los virus constituyen la segunda causa más importante de ETA en los Estados Unidos de América. Dos agentes, el virus Norwalk y el de la hepatitis A, ocuparon el quinto y sexto lugares, respectivamente, entre las causas principales de ETA, aunque el primero ocupó el primer puesto en 1982 y el segundo lugar como causa principal de enfermedades de transmisión hídrica durante el período de 1986 a 1988. A pesar de la escasez de datos al respecto, los rotavirus, poliovirus, virus de la hepatitis E, astrovirus y pequeños virus gastroentéricos también tienen importancia como agentes de ETA. En el artículo se discute también la importancia de las zoonosis víricas, especialmente de las fiebres hemorrágicas transmitidas por excretas de roedores y las encefalitis víricas transmitidas por garrapatas (fiebre difásica de la leche. Asimismo se presenta la polémica sobre la enfermedad de las vacas locas y su posible transmisión por los alimentos, además de los cuidados alimentarios relacionados con el sida y otras infecciones víricas. Por último, se describen los procedimientos de prevención y control de las ETA víricas.Throughout the world there have been several epidemics of food-borne diseases (FBD about which there is lack of sufficient information for public health institutions to take appropriate

    Equisetum giganteum L and Copaifera reticulate Ducke have been traditionally used by women of the Tacana tribe in the Bolivian Amazonas for genital hygiene and for treatment of genital infection/inflammation. To assess the ability of extracts from Equisetum giganteum L and Copaifera reticulate Ducke to block genital viral infection by herpes simplex virus type 2. Equisetum giganteum L and Copaifera reticulate Ducke were collected from the Amazon region of La Paz, Bolivia. Extracts were prepared and screened for anti-viral activity against herpes simplex virus type 2 (HSV-2) using both in vitro and in in vivo models of infection. Equisetum giganteum L and Copaifera reticulate Ducke efficiently blocked HSV-2 infection of cell cultures without major cell cytotoxic effects. Extracts of Equisetum giganteum L and Copaifera reticulate Ducke could prevent HSV-2 disease development when administered together with virus in a mouse model of genital HSV-2 infection. In vitro analyses revealed that both plant extracts exerted their anti-HSV-2 effects by interfering with viral cell attachment and entry, but could not block viral replication post entry. These studies show that extracts of Equisetum giganteum L and Copaifera reticulate Ducke have potent antiviral activities against HSV-2 comparable to those two previously identified plants, Croton lechleri Müll. Arg. and Uncaria tomentosa (Willd. ex Schult.) DC. These studies confirm that plants used by the Tacana tribe could be explored further for the development of novel topical antiviral microbicides.

    Female genital mutilation (FGM) is considered as the most dangerous custom still ritually practiced and 2 million girls undergo the ordeal each year. This practice is anchored and fixed firmly in numerous African people's culture and Western countries are confronted to it through African immigrants. In order to understand the justifications and the consequences of FGM we interviewed 14 genitally mutilated African women living in France. Unfortunately and despite the conscious knowledge of consequences and absurd side of such practice, yet it seems to be perpetuated over the descendants. Educational approach is the best solution to fight female genital mutilation fixed firmly in numerous African people's culture.

  10. Most important etiologic factors in the development of genital prolapse

    2010-01-01

    Full Text Available Introduction The incidence of genital prolapse depends on numerous factors. The contribution of race, gender and genetic factors is significant. However, additional factors of initiation, promotion and decomposition are necessary if a person with the genetic predisposition to genital prolapse begins to suffer from it. At least 50% of parous women are believed to suffer from genital prolapse of various degrees. Moreover, the prevalence of genital prolapse increases with age. The prevalence of genital prolapse is expected to be even higher in the future due to the extension of the lifespan of women worldwide. Objective The aim of this study was to determine the most common etiologic factors in the development of genital prolapse in the population of Serbia. Methods The study was conducted as prospective and included 50 women who underwent surgical treatment due to the problems caused by genital prolapse. Results Mean age of the women was 58.74 years. Twenty percent of the women had the menstrual cycle, while 80% were in menopause. Mean menopause period was 8.88 years. None of the women used hormone replacement therapy. Mean BMI was 27.395 kg/m2. Twenty-eight percent of the women were of normal weight, while 72% of the women were obese (42% were obese and 30% were severely obese. Ninety-eight percent of the women were parous, and mean parity was 2.08. Mean birth weight of neonates was 3682.77 g. Sixty-four percent of the women did physical labour and lifted heavy objects. Conclusion Vaginal childbirth is one of the most important initiating factors. The most significant promoting factor is obesity and heavy labour. Ageing and entering menopause are the most important factors of decomposition as well as the occurrence of clinical manifestations of the pelvic floor dysfunction. .

    Olfaction is often linked to mating behavior in nonhumans. Additionally, studies in mating behavior have shown that women seem to be more affected by odor cues than men. However, the relationship between odor cues and sexual response-specifically, sexual arousal-has not been studied yet. The aim of this study was to evaluate the impact of the exposure to human body odors (from individuals of the opposite gender) on perceived genital arousal, while these were presented concomitantly to sexually explicit video clips. Eighty university students (40 women) rated their perceived genital arousal (perceived degree of erection/genital lubrication) in response to an audiovisual sexual stimulus, while simultaneously exposed to a body odor from an opposite-gender donor or no odor. Participants also rated each odor sample's (body odor and no odor) perceived pleasantness, intensity, and familiarity. Findings indicated that odor condition had an effect on women's (but not men's) perceived genital arousal, with women showing higher levels of perceived genital arousal in the no odor condition. Also, results showed that women rated body odors as less pleasant than no odor. Notwithstanding, the odor ratings do not seem to explain the association between body odor and perceived genital arousal. The current results support the hypothesis that women, rather than men, are sensitive to odors in the context of sexual response. The findings of this study have relevance for the understanding of human sexuality with respect to chemosensory communication.

    OBJECTIVES: To determine the average cost of a case of genital warts, for both males and females, with a view to informing the current debate as to which Human papillomavirus vaccine would have maximum cost-effectiveness in the Irish population. METHODS: Contact time between patients and healthcare professionals was prospectively measured at five genitourinary medicine clinics in the south-west of Ireland, over a period of 3 weeks. By identifying all those with genital warts, it was possible to calculate the proportion of total time taken by patients with this condition, and from this to calculate a cost per incident case, by gender. RESULTS: A total of 25.5% of attendances were for genital warts, and these patients used 26.2% of total clinic time (CI 25.4 to 27.0%). The average cost calculated for genital warts was 335 euros per incident case, and by gender 300 euros per male case and 366 euros per female case. CONCLUSIONS: There are considerable costs associated with the treatment of genital warts, with female cases representing a higher cost than males. By vaccinating with the quadrivalent HPV vaccine, there are significant savings to be made.

    The implications for sexual abuse investigation of genital herpes in a child are uncertain because of a lack of good quality research evidence. The incidence, presenting features, history of exposure, indicators of child maltreatment and outcomes of child protection investigations in children with genital herpes are described. Ascertainment of all cases of genital herpes in children herpes simplex type 1, eight were tested for other sexually transmitted infections (STIs), and only one had a full STI screen. Three cases had other clinical features suggestive of sexual abuse. Six cases were referred for child protection investigation, but no sexual abuse was substantiated. Genital herpes in children under 11 years is rare. Almost a third of children diagnosed with genital herpes did not have appropriate virological investigation and few were screened for other STIs. Around a quarter of cases were referred to child protection agencies for further investigation, which limits any inferences in this study about mode of transmission in children. Sexual abuse guidance should emphasise the need for thorough assessment and investigation in cases of genital herpes in children.

  15. Exploiting Herpes Simplex Virus Entry for Novel Therapeutics

    Full Text Available Herpes Simplex virus (HSV is associated with a variety of diseases such as genital herpes and numerous ocular diseases. At the global level, high prevalence of individuals who are seropositive for HSV, combined with its inconspicuous infection, remains a cause for major concern. At the molecular level, HSV entry into a host cell involves multiple steps, primarily the interaction of viral glycoproteins with various cell surface receptors, many of which have alternate substitutes. The molecular complexity of the virus to enter a cell is also enhanced by the existence of different modes of viral entry. The availability of many entry receptors, along with a variety of entry mechanisms, has resulted in a virus that is capable of infecting virtually all cell types. While HSV uses a wide repertoire of viral and host factors in establishing infection, current therapeutics aimed against the virus are not as diversified. In this particular review, we will focus on the initial entry of the virus into the cell, while highlighting potential novel therapeutics that can control this process. Virus entry is a decisive step and effective therapeutics can translate to less virus replication, reduced cell death, and detrimental symptoms.

    Genital lesions are common in HIV positive patients and aetiology for these are mainly due to HSV, HPV or bacterial. They usually respond to HAART, antiviral or antimicrobials. We are presenting a young patient on HAART with non-healing genital ulcer lesions for sixteen months. He responded well to a change in ART regimen within a period of 15 days. This happened after a change to a more potent ART regimen.

    Full Text Available Background: Protection from naturally acquired human papillomavirus (HPV antibodies may influence HPV infection across the lifespan. This study describes seroconversion rates following genital, anal, and oral HPV 6/11/16/18 infections in men and examines differences by HPV type and anatomic site. Methods: Men with HPV 6/11/16/18 infections who were seronegative for those genotypes at the time of DNA detection were selected from the HPV Infection in Men (HIM Study. Sera specimens collected ≤36 months after detection were analyzed for HPV 6/11/16/18 antibodies using a virus-like particle-based ELISA. Time to seroconversion was separately assessed for each anatomic site, stratified by HPV type. Results: Seroconversion to ≥1 HPV type (6/11/16/18 in this sub-cohort (N=384 varied by anatomic site, with 6.3%, 18.9%, and 0.0% seroconverting following anal, genital, and oral HPV infection, respectively. Regardless of anatomic site, seroconversion was highest for HPV 6 (19.3%. Overall, seroconversion was highest following anal HPV 6 infection (69.2%. HPV persistence was the only factor found to influence seroconversion. Conclusions: Low seroconversion rates following HPV infection leave men susceptible to recurrent infections that can progress to HPV-related cancers. This emphasizes the need for HPV vaccination in men to ensure immune protection against new HPV infections and subsequent disease.

  1. Adhesion Molecules Associated with Female Genital Tract Infection.

    Directory of Open Access Journals (Sweden)

    Jamal Qualai

    Full Text Available Efforts to develop vaccines that can elicit mucosal immune responses in the female genital tract against sexually transmitted infections have been hampered by an inability to measure immune responses in these tissues. The differential expression of adhesion molecules is known to confer site-dependent homing of circulating effector T cells to mucosal tissues. Specific homing molecules have been defined that can be measured in blood as surrogate markers of local immunity (e.g. α4β7 for gut. Here we analyzed the expression pattern of adhesion molecules by circulating effector T cells following mucosal infection of the female genital tract in mice and during a symptomatic episode of vaginosis in women. While CCR2, CCR5, CXCR6 and CD11c were preferentially expressed in a mouse model of Chlamydia infection, only CCR5 and CD11c were clearly expressed by effector T cells during bacterial vaginosis in women. Other homing molecules previously suggested as required for homing to the genital mucosa such as α4β1 and α4β7 were also differentially expressed in these patients. However, CD11c expression, an integrin chain rarely analyzed in the context of T cell immunity, was the most consistently elevated in all activated effector CD8+ T cell subsets analyzed. This molecule was also induced after systemic infection in mice, suggesting that CD11c is not exclusive of genital tract infection. Still, its increase in response to genital tract disorders may represent a novel surrogate marker of mucosal immunity in women, and warrants further exploration for diagnostic and therapeutic purposes.

    Colonization by Lactobacillus in the female genital tract is thought to be critical for maintaining genital health. However, little is known about how genital microbiota influence host immune function and modulate disease susceptibility. We studied a cohort of asymptomatic young South African women and found that the majority of participants had genital communities with low Lactobacillus abundance and high ecological diversity. High-diversity communities strongly correlated with genital pro-inflammatory cytokine concentrations in both cross-sectional and longitudinal analyses. Transcriptional profiling suggested that genital antigen-presenting cells sense gram-negative bacterial products in situ via Toll-like receptor 4 signaling, contributing to genital inflammation through activation of the NF-κB signaling pathway and recruitment of lymphocytes by chemokine production. Our study proposes a mechanism by which cervicovaginal microbiota impact genital inflammation and thereby might affect a woman's reproductive health, including her risk of acquiring HIV.

    Full Text Available Herpes simplex virus type 1 (HSV-1 with a worldwide distribution has been reported in all human populations, resulting in a clinical spectrum of infections. Although HSV type 2 (HSV-2 is known as the most common cause of genital herpes, an increasing number of cases with genital herpes are caused by HSV-1. The present study aimed to discuss the changes in the epidemiology of HSV-1 infection including the decline in the general incidence of HSV-1 infection in childhood and the increased rate of genital herpes, caused by HSV-1. Moreover, changes in the epidemiology of ocular herpes, i.e., the reduced rate of primary ocular herpes in children and increased incidence of ocular HSV infection in adults, were discussed.

    To measure the prevalence of chlamydial genital infection in Ethiopian women attending gynaecological, obstetric and family planning clinics; to identify the epidemiological, social and economic factors affecting the prevalence of infection in a country where routine laboratory culture and serological tests for chlamydial species are unavailable; to determine the risk factors for genital chlamydial infection in those with serological evidence of other sexually transmitted diseases. 1846 Ethiopian women, outpatient attenders at two teaching hospitals and a mother and child health centre in Addis Ababa, Ethiopia. Gynaecological outpatient department, antenatal, postnatal and family planning clinics. Sera were tested for type-specific anti-chlamydial antibodies using purified chlamydial antigens (C. trachomatis A-C (CTA-C), C. trachomatis D-K (CTD-K), Lymphogranuloma venereum (LGV1-3), and C. pneumoniae (CPn)), in a micro-immunofluorescence test. The genital chlamydia seropositivity was analysed against patient's age, clinic attended, ethnic group, religion, origin of residence, age at first marriage and first coitus, income, number of sexual partners, duration of sexual activity, marital status/profession, obstetric and contraceptive history, and seropositivity for other sexually transmitted diseases. Overall exposure to chlamydia species was found in 84%, genital chlamydial infection in 62%, and titres suggestive of recent or present genital infection in 42% of those studied. Genital chlamydial infection was highest (64%) in family planning and lowest (54%) in antenatal clinic attenders. Exposure to genital chlamydia species was influenced by ethnic group and religion. Those married and sexually active under 13 years of age had greater exposure (69%) to genital chlamydial infection than those first sexually active aged over 18 (46%). Prevalence of infection was highest in those with more than five sexual partners (78%) and in bargirls (84%). The lowest income groups

    The efficacy of BAY 57-1293, a novel non-nucleosidic inhibitor of herpes simplex virus 1 and 2 (HSV-1 and HSV-2), bovine herpesvirus and pseudorabies virus, was studied in the guinea pig model of genital herpes in comparison with the licensed drug valaciclovir (Valtrex). Early therapy with BAY 57-1293 almost completely suppressed the symptoms of acute HSV-2 infection, and reduced virus shedding and viral load in the sacral dorsal root ganglia by up to three orders of magnitude, resulting in decreased latency and a greatly diminished frequency of subsequent recurrent episodes. In contrast, valaciclovir showed only moderate effects in this set of experiments. When treatment was initiated late during the course of disease after symptoms were apparent, that is, a setting closer to most clinical situations, the efficacy of therapy with BAY 57-1293 was even more pronounced. Compared with valaciclovir, BAY 57-1293 halved the time necessary for complete healing. Moreover, the onset of action was fast, so that only very few animals developed new lesions after treatment commenced. Finally, in a study addressing the treatment of recurrent disease in animals whose primary infection had remained untreated BAY 57-1293 was efficient in suppressing the episodes. In summary, superior potency and efficacy of BAY 57-1293 over standard treatment with valaciclovir was demonstrated in relevant animal models of human genital herpes disease in terms of abrogating an HSV infection, reducing latency and the frequency of subsequent recurrences. Furthermore, BAY 57-1293 shortens the time to healing even if initiation of therapy is delayed.

    The high prevalence of female genital mutilation has been a concern in Iraqi Kurdistan. This study was undertaken to estimate its prevalence and describe factors associated with its occurrence. A cross-sectional survey was undertaken from March to April 2011 of females aged up to 20 years using interviews and clinical examination. The survey included 1,508 participants with mean age of 13.5 years (SD 5.6). Overall female genital mutilation prevalence was 23%, and the mean age at which it had been performed was 4.6 years (SD 2.4). Type I (partial or total removal of the clitoris) comprised 76% of those who had had female genital mutilation; in 79% of cases the decision to perform it was made by the mother; and in 54% of cases it was performed by traditional birth attendants/midwives. Women aged 16 years and over were more likely to have had female genital mutilation compared to children aged below 6 years (OR 11.9, p Kurdistan region were more likely to have been circumcised. The study results show that female genital mutilation is a frequent practice in Iraqi Kurdistan. Attention and intervention is needed to address this aspect of the well-being of girls and women.

    Recently, we showed that HIV-1 is sequestered, i.e., trapped, in the intracellular vesicles of oral and genital epithelial cells. Here, we investigated the mechanisms of HIV-1 sequestration in vesicles of polarized tonsil, foreskin and cervical epithelial cells. HIV-1 internalization into epithelial cells is initiated by multiple entry pathways, including clathrin-, caveolin/lipid raft-associated endocytosis and macropinocytosis. Inhibition of HIV-1 attachment to galactosylceramide and heparan sulfate proteoglycans, and virus endocytosis and macropinocytosis reduced HIV-1 sequestration by 30–40%. T-cell immunoglobulin and mucin domain 1 (TIM-1) were expressed on the apical surface of polarized tonsil, cervical and foreskin epithelial cells. However, TIM-1-associated HIV-1 macropinocytosis and sequestration were detected mostly in tonsil epithelial cells. Sequestered HIV-1 was resistant to trypsin, pronase, and soluble CD4, indicating that the sequestered virus was intracellular. Inhibition of HIV-1 intraepithelial sequestration and elimination of vesicles containing virus in the mucosal epithelium may help in the prevention of HIV-1 mucosal transmission. PMID:29277006

    Genital injuries among children are often associated with consumer products or specific activities. There are few descriptive studies from Asia on pediatric genital injuries seen in the emergency department (ED). The aim of this study was to describe the characteristic features of accidental genital injuries among children. A retrospective chart review of children aged 15 years or younger who visited our ED for genital injuries between March 2010 and November 2014 was conducted. Data on age, arrival time at the ED, location of the incident, mechanism of injury, objects, injured organ, consultation with specialists, emergency operation, sedation at the ED, and outcomes were collected and analyzed. One hundred seventy-nine patients were included in this analysis. Girls comprised 71% of the subject pool. The median age was 6 years (interquartile range, 4-9 years). Straddle injuries were the most common form of injury (56%). Male genital injuries occurred mostly outdoors (64%). Common consumer products associated with pediatric genital injuries were furniture (21%), exercise equipment (17%), and bicycles (15%). Thirty-two patients were examined by a surgeon, gynecologist, or urologist. The most commonly injured organs were the penis (55%) in boys and the labia (60%) in girls. Most patients (93%) were treated at the ED and discharged. The characteristics of accidental genital injuries among Japanese children were similar to those of children in other countries. The strategy for preventing genital injuries used in the West might be applicable to the East Asian context.

This study evaluated 200 women with and without genital squamous intraepithelial lesion who were recruited for anal Pap smears. Women who had abnormal results on equally or over atypical squamous cells of undetermined significance were classified as having abnormal anal cytology. A multiple logistic regression analysis (stepwise was performed to identify the risk for developing abnormal anal cytology. Data were analyzed using the SPSS 20.0 program. The average age was 41.09 (±12.64. Of the total participants, 75.5% did not practice anal sex, 91% did not have HPV-infected partners, 92% did not have any anal pathology, and 68.5% did not have anal bleeding. More than half (57.5% had genital SIL and a significant number developed abnormal anal cytology: 13% in the total sample and 17.4% in women with genital SIL. A significant association was observed between genital squamous intraepithelial lesion and anal squamous intraepithelial lesion (PR = 2.46; p = 0.03. In the logistic regression model, women having genital intraepithelial lesion were more likely to have abnormal anal Pap smear (aPR = 2.81; p = 0.02. This report shows that women with genital squamous intraepithelial lesion must be more closely screened for anal cancer.

    Full Text Available Ahmad K Abou-Foul, Thajunisha M Buhary, Sedki L Gayed Department of Genitourinary Medicine, Royal Blackburn Hospital, East Lancashire Hospitals NHS Trust, Blackburn, UK Introduction: Cases of idiopathic recurrent benign aseptic meningitis were first described by Mollaret. Today, herpes simplex virus (HSV is considered the cause of most cases of Mollaret's meningitis. Case report: A 40-year-old male was referred to our genitourinary medicine clinic with recurrent genital herpetic lesions. He had HSV-2-positive genital ulcers 8 years earlier. One year after the first infection, he developed severe recurrent attacks of headache associated with meningitis symptoms. The results of all radiological and biochemical tests were normal, but the patient reported a correlation between his attacks and genital herpes flare-ups. We diagnosed the patient with Mollaret's meningitis and started him on continuous suppressive acyclovir therapy, which resulted in marked clinical improvement. Discussion: Mollaret's meningitis is a rare form of idiopathic recurrent aseptic meningitis that has a sudden onset, short duration, and spontaneous remission with unpredictable recurrence. We believe that the presence of concurrent or recurrent mucocutaneous herpetic lesions can aid its diagnosis, prior to which, affected patients usually have many unnecessary investigations and treatments. Therefore, detailed sexual history should be sought in all patients with aseptic meningitis, and clinicians should also ask about history of recurrent headaches in all patients with recurrent herpetic anogenital lesions. Continuous suppressive acyclovir therapy may reduce the frequency and severity of attacks and can dramatically improve lifestyle.

    Persistent genital arousal disorder (PGAD) is an understudied condition characterized by unwanted physiologic genital arousal in the absence of subjective sexual arousal. Markos and Dinsmore (Int J STD AIDS 2013;24:852-858) theorized that PGAD shares a number of similarities with vulvodynia (unexplained chronic vulvar pain [CVP]), including symptom characteristics and comorbidities. To compare medical histories, symptom characteristics, pain characteristics, and daily functioning among women with persistent genital pain (PGA) (n = 42), painful PGA (n = 37), and CVP (n = 42) symptoms. An online cross-sectional survey was conducted from October 2015 through April 2016. Self-report measures of symptoms, diagnosed medical conditions, pain characteristics (McGill Pain Questionnaire), catastrophizing (Pain Catastrophizing Scale), and daily functioning (Functional Status Questionnaire) were collected. All 3 groups reported similar medical diagnoses and high frequencies of other chronic pelvic pain conditions. Women in all 3 groups reported comparable ages at symptom onset and timing of symptom expression (ie, constant vs intermittent). Women in the 2 PGA groups reported significantly greater feelings of helplessness than women in the CVP group. Women in the painful PGA and CVP groups endorsed significantly more sensory terms to describe their symptoms compared with women in the PGA group, whereas women in the painful PGA group reported significantly more affective terms to describe their symptoms compared with women in the CVP group. Women in the 2 PGA groups reported that their symptoms interfered significantly with most areas of daily functioning. Given the similarities between PGA and CVP symptoms, women with PGA may benefit from similar assessment, treatment, and research approaches. Limitations of the present study include its sole use of self-report measures; the presence of PGA or CVP symptoms was not confirmed by clinical assessment. However, the anonymous

    Genital automatisms (GAs) are uncommon clinical phenomena of focal seizures. They are defined as repeated fondling, grabbing, or scratching of the genitals. The aim of this study was to determine the lateralizing and localizing value and associated clinical characteristics of GAs. Three hundred thirteen consecutive patients with drug-resistant seizures who were referred to our tertiary center for presurgical evaluation between 2009 and 2016 were investigated. The incidence of specific kinds of behavior, clinical semiology, associated symptoms/signs with corresponding ictal electroencephalography (EEG) findings, and their potential role in seizure localization and lateralization were evaluated. Fifteen (4.8%) of 313 patients had GAs. Genital automatisms were identified in 19 (16.4%) of a total 116 seizures. Genital automatisms were observed to occur more often in men than in women (M/F: 10/5). Nine of fifteen patients (60%) had temporal lobe epilepsy (right/left: 4/5) and three (20%) had frontal lobe epilepsy (right/left: 1/2), whereas the remaining two patients could not be classified. One patient was diagnosed as having Rasmussen encephalitis. Genital automatisms were ipsilateral to epileptic focus in 12 patients and contralateral in only one patient according to ictal-interictal EEG and neuroimaging findings. Epileptic focus could not be lateralized in the last 2 patients. Genital automatisms were associated with unilateral hand automatisms such as postictal nose wiping or manual automatisms in 13 (86.7%) of 15 and contralateral dystonia was seen in 6 patients. All patients had amnesia of the performance of GAs. Genital automatisms are more frequent in seizures originating from the temporal lobe, and they can also be seen in frontal lobe seizures. Genital automatisms seem to have a high lateralizing value to the ipsilateral hemisphere and are mostly concordant with other unilateral hand automatisms. Men exhibit GAs more often than women.

    Background: Postmenopausal bleeding (PMB) is bleeding occurring after 6-12 months of amenorrhea in a woman of age where the menopause can be expected. Objectives of this study were to ascertain various causes and prevalence of genital organ malignancy in patients presenting with postmenopausal bleeding. Methods: A prospective observational study carried out in the Department of Obstetrics and Gynaecology, Fauji Foundation Hospital, Rawalpindi comprising of 167 consecutive cases presenting with postmenopausal bleeding one year after menopause. Women having undergone hysterectomy and bilateral salpingo-oophorectomy, receiving radiotherapy or chemotherapy, suffered trauma to the genital tract, having coagulation disorder or on anticoagulant or hormone replacement therapy were excluded. Detailed history was obtained and a thorough clinical examination was conducted. Data were entered into hospital computer database (Medix) system. Mean +- SD were calculated for age, percentage was calculated for types of histopathological findings. Results: The commonest cause of PMB was atrophic endometritis and vaginitis 33 (21.2%). Overall incidence of various genital tract malignancies was 25 (16.0%). Conclusion: The overall incidence of genital tract malignancies in patients presenting with PMB is high (16.0%), therefore, it needs to be taken seriously and requires prompt and thorough investigations.

    A 33-year-old man was referred to our institution with papillary masses at the urethral meatus and difficulty urinating. Genital examination showed two piercings on the frenulum, which were penetrating the external urethra. Endoscopic examination revealed papillary tumours over the entire circumference of the penile urethra and the piercing site. The tumours were resected transurethrally. Microscopic examination revealed condylomata acuminata. Human papillomavirus types 6 and 66 were detected in the lesions. Retrograde urethral viral infection is rare because of the protection provided by the mucosal immune system. Genital piercing may have facilitated spread of the human papillomavirus into the urethra.

    2012-02-01

    There is considerable debate within the literature about the significance of human papilloma virus in head and neck squamous cell carcinoma, and its potential influence on the prevention, diagnosis, grading, treatment and prognosis of these cancers. Cigarette smoking and alcohol consumption have traditionally been cited as the main risk factors for head and neck cancers. However, human papilloma virus, normally associated with cervical and other genital carcinomas, has emerged as a possible key aetiological factor in head and neck squamous cell carcinoma, especially oropharyngeal cancers. These cancers pose a significant financial burden on health resources and are increasing in incidence. The recent introduction of vaccines targeted against human papilloma virus types 16 and 18, to prevent cervical cancer, has highlighted the need for ongoing research into the importance of human papilloma virus in head and neck squamous cell carcinoma.

    Very widespread in our clinical setting, early-onset sepsis is due to organisms that commonly colonize or infect the maternal genital tract; identifying such organisms would help improve prevention and treatment. To determine the bacterial ecology and the pathological status of the genital organs during the last trimester of pregnancy, in order to evaluate the risk of materno-fetal infections and to improve the present prophylactic measures based on monitoring bacterial carriage during the first trimester. Vaginal and endocervical samples, usually taken during the first trimester of pregnancy were delayed and taken during the last trimester of pregnancy, in patients with no signs of sepsis and not taking antibiotics. A macroscopic examination described the aspect of the vagina, the cervix uteri, leukorrhea and possible inflammatory lesions or ulcerations. A microscopic examination searched for parasites, epithelial cells, Clue cells and leukocytes. The appropriate bacteriological cultures were performed after reading the Gram stain and scoring the vaginal flora. The clinical and cytobacteriological aspects were used to identify the bacterial ecology and the pathological genital states. Genital samples were collected from 306 pregnant women. Among them 118 were at 29-32 weeks of gestation, 104 at 33-36 and 84 at 37-40. The most frequent germs were C. albicans (33.3%), Enterobacteriaceae (20.3%) including E. coli (10.9%), S. aureus (15.4%), Gardnerella (13.6%), and Trichomonas (10.6%), in monomicrobian (79.2%) or polymicrobian carriage (20.8%). Lower genital tract pathological states such as vaginitis (29.4%), bacterial vaginosis (21.5%) or cervicitis (10.4%) and asymptomatic bacterial carriage (23.5%) and normal genital flora (15%) were identified. This is the first report of genital bacterial carriage in African women during the last trimester of pregnancy. Larger studies are required to evaluate the risk of maternofetal infections and to improve current

    Full Text Available Introduction. Pityriasis lichenoides is a rare, acquired spectrum of skin conditions of an unknown etiology. Case Report. A 28-year-old man presented with recurrent outbreaks of herpes simplex virus associated with the onset of red-to-brown maculopapules located predominantly in trunk in each recurrence. Positive serologies to herpes simplex virus type 2 were detected. Histopathological examination of one of the lesions was consistent with a diagnosis of pityriasis lichenoides chronica. Discussion. Pityriasis lichenoides is a rare cutaneous entity of an unknown cause which includes different clinical presentations. A number of infectious agents have been implicated based on the clustering of multiple outbreaks and elevated serum titers to specific pathogens (human immunodeficiency virus, cytomegalovirus, Epstein-Barr virus, Toxoplasma gondii, and herpes simplex virus. In our patient, resolution of cutaneous lesions coincided with the administration of antiviral drugs and clinical improvement in each genital herpes recurrence. In conclusion, we report a case in which cutaneous lesions of pityriasis lichenoides chronica and a herpes simplex virus-type 2-mediated disease have evolved concomitantly.

    The goal of this study was to identify the causes and factors associated with genital ulcer disease (GUD) among patients attending a sexually transmitted disease (STD) clinic in Paris. This study was a prospective investigation of GUD cases. Data were collected from 1995 to 2005. In each case, a Dark Field Examination (DFE), Gram stain, inoculation onto Thayer Martin agar, Columbia agar and chocolate agar with 1% isovitalex and 20% fetal calf serum, PCR Chlamydia trachomatis (Amplicor Roche), culture for herpes simplex virus (HSV) on MRC 5 cells and PCR HSV (Argene Biosoft) were obtained from the ulceration. First Catch Urine (FCU) PCR for Chlamydia trachomatis and syphilis, HIV, HSV, and HBV serologies were also performed. A total 278 cases of GUD were investigated, 244 (88%) in men and 34 (12%) in women. Primary syphilis accounted for 98 cases (35%), genital herpes for 74 (27%), chancroid for 8 (3%), other infections for 12 (5%). In 91 (32%) patients, no identifiable microorganism was documented. Primary syphilis was more prevalent in MSMs (P chancroid were significantly associated with heterosexuality (both P 10 mm (OR: 9.2 [95% CI: 2.9-30.7], P chancroid and reemergence of infectious syphilis have led to a new distribution of pathogens, genital herpes, primary syphilis and GUD from unknown origin, accounting each for one third of cases.

    HPV-11 and HPV-6 are the etiological agents of about 90 % of genital warts (GWs). The intra-typic variability of HPV-11 and its association with infection persistence and GW development remains undetermined. Here, HPV infection in men (HIM) participants who had an HPV-11 genital swab and/or GW, preceded or not by a normal skin genital swab were analysed. Genomic variants were characterized by PCR-sequencing and classified within lineages (A, B) and sublineages (A1, A2, A3, A4). HPV-11 A2 variants were the most frequently detected in the genital swab samples from controls and in both genital swabs and GW samples from cases. The same HPV-11 variant was detected in the GW sample and its preceding genital swab. There was a lack of association between any particular HPV-11 variant and the increased risk for GW development.

    Body piercing has gained tremendous popularity since the mid nineties. Genital piercings constitute a peculiar variant of piercing due to its sensitive localization. Health care providers are often very little informed about those piercings. Besides, negative stereotypes are often attributed to the bearers of such piercings. This review focuses not only on the medical aspects of genital piercings but also on the social, cultural and psychological background that surround those piercings.

    Genital herpes is caused by herpes simplex virus 1 (HSV-1) or 2 (HSV-2). Some infected people experience outbreaks of genital herpes, typically, characterized by vesicular and erosive localized painful genital lesions. To compare the effectiveness and safety of three oral antiviral drugs (acyclovir, famciclovir and valacyclovir) prescribed to suppress genital herpes outbreaks in non-pregnant patients. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the search portal of the World Health Organization International Clinical Trials Registry Platform and pharmaceutical company databases up to February 2014. We also searched US Food and Drug Administration databases and proceedings of seven congresses to a maximum of 10 years. We contacted trial authors and pharmaceutical companies. We selected parallel-group and cross-over randomized controlled trials including patients with recurrent genital herpes caused by HSV, whatever the type (HSV-1, HSV-2, or undetermined), with at least four recurrences per year (trials concerning human immunodeficiency virus (HIV)-positive patients or pregnant women were not eligible) and comparing suppressive oral antiviral treatment with oral acyclovir, famciclovir, and valacyclovir versus placebo or another suppressive oral antiviral treatment. Two review authors independently selected eligible trials and extracted data. The Risk of bias tool was used to assess risk of bias. Treatment effect was measured by the risk ratio (RR) of having at least one genital herpes recurrence. Pooled RRs were derived by conventional pairwise meta-analyses. A network meta-analysis allowed for estimation of all possible two-by-two comparisons between antiviral drugs. A total of 26 trials (among which six had a cross-over design) were included. Among the 6950 randomly assigned participants, 54% (range 0 to 100%) were female, mean age was 35 years (range 26 to 45.1), and the mean number of recurrences per year was 11

    Ureaplasmas have been implicated in a variety of clinical conditions. However, only certain serovars of ureaplasmas are disease associated. Only a few classes of antimicrobial agents are available for the treatment of mycoplasmal infections in humans. Increase of resistance of genital mycoplasmas to antimicrobials has been reported worldwide. The aim of the present study was to determine the occurrence of Ureaplasma serovars in patients with infertility and genital tract infections with polymerase chain reaction (PCR)-based serotyping. The antimicrobial susceptibilities of Ureaplasma spp. and Mycoplasma hominis were also assessed to determine the most suitable treatment strategy. Sexually active adults (n=147) with symptoms of genital tract infections and 115 infertile women were enrolled. Endocervical swabs from women and urethral swabs from men were subjected to culture and multiplex PCR for detection of genital mycoplasmas. Serotyping of Ureaplasma was done by PCR and antimicrobial susceptibility to doxycycline, azithromycin, josamycin and ofloxacin was done by microbroth dilution method. Ureaplasma was detected in 25.8 per cent patients with genital tract infections and 20.8 per cent in infertile women. Serovar 3/14 was the most frequent isolate followed by serovar 1 and serovar 6. The majority of Ureaplasma isolates were susceptible to doxycycline (91%) and josamycin (86%) followed by ofloxacin (77%) and azithromycin (71%). All the isolates of M. hominis were uniformly susceptible to doxycycline, josamycin and ofloxacin. The predominance of Ureaplasma serovar 3/14 suggests their possible pathogenic role in genital tract infections and infertility. For empirical treatment, doxycycline could be the drug of choice for genital mycoplasmas.

    The study aimed to gauge the perceptions of Canadians toward genital warts, related health behaviors, and treatment preferences. An online survey supported by an unrestricted grant from Graceway Canada was conducted in February 2011 by Leger Marketing. It included 9 demographic questions and 17 questions relating to genital wart perception (2 multiple-choice, 15 four-point rating from strongly agree to strongly disagree). The survey was completed by 1520 Canadian adults aged 18 to older than 75 years, of whom 52% (786/1520) were female. Fifty-two percent of respondents stated that they would monitor an unrecognized spot on their genitals, and only seek medical assistance if it did not go away. Only 43% (652/1520) said that they would stop having sex until the spots were gone. Although only 10% (158/1520) of respondents stated that they would not inform their partner, this was much higher among men (14%, 103/734) than women (7%, 55/786), with p ≤ .01. Concerns of being judged by friends/family were high (44%, 669/1520), especially among younger (18-34 y) Canadians (60%), with p ≤ .05. Regarding prevention, 32% (493/1520) of respondents believed that monogamy would protect against genital warts and 25% (373/1520) believed they are not at risk if they use a condom. Treatment preference was in favor of a cream rather than an "invasive" treatment (58%, 886/1520), particularly among younger (67%, 283/425, p ≤ .05) and male respondents (63%, 464/734, p ≤ .01). Sixty percent (921/1520) would worry that genital warts could not be resolved; and 44% (668/1520), that they would recur. Among Canadians, genital warts were associated with a fair degree of social stigma and potential negative impact on their psyche, especially for younger Canadians.

    Donovanosis is a chronic indolent sexually transmitted granulomatous ulceration of genito-inguinal region, caused by Calymmatobacterium granulomatis. It became uncommon due to indiscriminate use of broad spectrum antibiotics. In recent years, much interest is being focused on this condition because genital ulcers facilitate HIV infection. We report an interesting episode of genital donovanosis complicated with squamous cell carcinoma in a middle aged female for its rarity and clinical interest.

    Genital papilloma is caused by human papilloma virus (HPV) infection and recurs frequently. Although T cells are known to play a critical role in the control of HPV infection and papilloma development, the function and phenotype of these cells in the lesion remain to be elucidated. In the present study, we examined the function and phenotype of CD4(+) T cells isolated from the lesions of primary (n = 9) and recurrent (n = 11) genital papillomas. In recurrent papillomas, the frequency of proliferating (Ki-67(+)) CD4(+) T cells was significantly reduced compared with primary papillomas. Cytokine production was evaluated by intracellular cytokine staining in anti-CD3/anti-CD28-stimulated CD4(+) T cells. CD4(+) T cells from recurrent lesions showed impaired production of IL-2, IFN-γ, and TNF-α. Of interest, the frequency of cytokine-producing CD4(+) T cells significantly correlated with the frequency of Ki-67(+)CD4(+) T cells. We also studied expression of programmed death-1 (PD-1), a T-cell exhaustion marker. The frequency of PD-1(+)CD4(+) T cells was significantly increased in recurrent lesions and inversely correlated with the frequency of cytokine-producing CD4(+) T cells. The functional significance of PD-1 expression was determined in blocking assays with anti-PD-L1, which restored cytokine production of CD4(+) T cells from recurrent lesions. Taken together, in recurrent genital papilloma lesions, proliferation, and cytokine production by CD4(+) T cells are impaired and the PD-1/PD-L1 interaction is responsible for the functional impairment of CD4(+) T cells.

    Many sexual psychophysiologic studies have failed to find differences in physiologic genital arousal between women with and those without sexual dysfunction. However, differences in self-reported (ie, perceived) measures of genital responses between these 2 groups of women have been noted. To determine whether women with and without sexual dysfunction differ on measures of physiologic and perceived genital arousal based on type of analytic technique used, to explore differences in perceived genital arousal, and to assess the relation between physiologic and perceived genital arousal. Data from 5 studies (N = 214) were used in this analysis. Women were categorized into 3 groups: women with arousal-specific sexual dysfunction (n = 40), women with decreased sexual function (n = 72), and women who were sexually functional (n = 102). Women viewed an erotic film while their physiologic genital arousal was measured using a vaginal photoplethysmograph. After watching the film, women completed a self-report measure of perceived genital arousal. There were differences in vaginal pulse amplitude (VPA) levels and association of VPA with perceived genital sensations based on level of sexual function. Commonly used methods of analysis failed to identify significant differences in VPA among these groups of women. When VPA data were analyzed with hierarchical linear modeling, significant differences emerged. Notably, women with arousal-specific dysfunction exhibited lower VPA than sexually functional women at the beginning of the assessment. As the erotic film progressed, women with arousal-specific dysfunction became aroused at a faster rate than sexually functional women, and these 2 groups ultimately reached a similar level of VPA. Sexually functional women reported the highest levels of perceived genital responses among the 3 groups of women. No significant relation between VPA and perceived genital arousal emerged. Women's perception of their genital responses could play

    Full Text Available Limited data are available on the prevalence of genital mycoplasmas and Chlamydia trachomatis (CT among Indian patients with genital tract infections. The objectives of the study were to determine the prevalence of Ureaplasma urealyticum (UU, Mycoplasma hominis (MH, Mycoplasma genitalium (MG, and CT in patients with genital tract infections. The antimicrobial susceptibilities of UU and MH were also assessed. Endocervical swabs/urethral swabs and first void urine samples of patients (n = 164 were collected. UU and MH were detected by culture and multiplex polymerase chain reaction (PCR. MG and CT were identified by PCR. Ureaplasma isolates were further biotyped and serotyped. Antimicrobial susceptibility was done by microbroth dilution method. UU, MH, MG, and CT were detected in 15.2%, 5.4%, 1.2%, and 6% patients, respectively. Ureaplasma parvum serovar 3/14 was the most prevalent. All isolates of UU and MH were uniformly susceptible to doxycycline and josamycin. Routine screening for these pathogens and antimicrobial susceptibility testing is warranted to prevent sequel of infections and formulate treatment guidelines.

    Microbial infections of the chorioamnion and amniotic fluid have devastating effects on pregnancy outcome and neonatal morbidity and mortality. The mechanisms by which bacterial pathogens cause adverse effects are best addressed by an animal model of the disease with a naturally-occurring pathogen. Intrauterine infection in humans as well as genital mycoplasmosis in humans and rodents is reviewed. We describe a genital infection in rats, which provides a model for the role of infection in pregnancy, pregnancy wastage, low birth weight, and fetal infection. Infection of Sprague-Dawley rats with Mycoplasma pulmonis either vaginally or intravenously resulted in decreased litter size, increased adverse pregnancy outcome, and in utero transmission of the microorganism to the fetus. Mycoplasma pulmonis is an ideal model to study maternal genital infection during pregnancy, the impact of infections on pregnancy outcome, fetal infection, and maternal-fetal immune interactions.

    Full Text Available Female genital tuberculosis (TB remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome (AIDS. Genital TB is commonly asymptomatic, and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools, such as computerized tomography (CT scan, magnetic resonance imaging (MRI and ultrasongraphy, hysterosalpingography is still the standard screening test for evaluation of tubal infertility and a valuable tool for diagnosis of female genital tuberculosis. Tuberculosis gives rise to various appearances on hysterosalpingography (HSG from non-specific changes to specific findings. The present pictorial review illustrates and describes specific and non-specific radiographic features of female genital tuberculosis in two parts. Part I presents specific findings of tuberculosis related to tubes such as "beaded tube", "golf club tube", "pipestem tube", "cobble stone tube" and "leopard skin tube". Part II describes adverse effects of tuberculosis on structure of endometrium and radiological specific findings such as "dwarfed" uterus with lymphatic intravasation and occluded tubes, "T-shaped" tuberculosis uterus, "pseudounicornuate" uterus and "Collar-stud abscess", which have not been encountered in the majority of non-tuberculosis cases.

    2002-01-01

    Objective: To assess whether syndromic management of genital ulcer disease was sound, if based on the premise that men with genital ulcers rarely have a concomitant urethral infection. Methods: Specimens were taken in 1998 from 186 mine workers in Carletonville, South Africa, who were seen consecutively with genital ulcers. The specimens comprised a swab from the ulcer, a urethral swab for a Gram stained smear, and 10–15 ml of a first catch urine sample. The latter was tested by ligase chain reaction assays for Neisseria gonorrhoeae and Chlamydia trachomatis specific DNA sequences and by a polymerase chain reaction (PCR) assay for Mycoplasma genitalium. Ulcer inducing micro-organisms were detected either by a multiplex PCR assay, or in the case of lymphogranuloma venereum (LGV) serologically, and human immunodeficiency virus (HIV) infection was detected by an enzyme linked immunosorbent assay (ELISA) test. Results: Most (54%) of the ulcers were chancroidal, 18% were herpetic (HSV type 2), 6.5% primary syphilitic, and 3.2% due to LGV. More than one micro-organism was detected in 9.1% of the ulcers and less than 10% were undiagnosed. Microscopic examination of the urethral smears showed that 99 (53%) of the men had urethritis, of whom 45 (45%) were infected with N gonorrhoeae. Of the 54 men (55%) who had non-gonococcal urethritis (NGU), 11 (19.6%) harboured C trachomatis or M genitalium. Almost two thirds (64.5%) of the men had HIV infection, but this did not seem to have influenced the aetiology of the ulcers. Nor was a particular ulcer associated with one type of urethritis more than the other. Neither C trachomatis nor M genitalium was associated significantly with non-gonococcal urethritis (NGU) in either HIV positive or HIV negative men. Conclusion: The combination of antibiotics used for the management of genital ulcer disease in men in this South African mining population needs to be widened to encompass frequently occurring concomitant gonococcal urethritis

  11. Positive Perceptions of Genital Appearance and Feeling Sexually Attractive: Is It a Matter of Sexual Esteem?

    The present study examined the relationship between perceptions of genital appearance and self-perceived sexual attractiveness. The study sample included men and women (aged 18-45 years, M = 23.7, SD = 4.98) who identified as heterosexual (n = 1017), gay or lesbian (n = 1225), or bisexual (n = 651). Participants responded to an online survey assessing their self-perceived sexual attractiveness, genital self-image, genital self-consciousness during sexual activity, and sexual esteem. Based on previous findings, we hypothesized a positive link between genital self-perceptions and self-perceived sexual attractiveness, with sexual esteem acting as a mediator. We tested this hypothesis using structural equation modeling. Analyses revealed a significant association between both genital self-image and genital self-consciousness and self-perceived sexual attractiveness. However, these relationships were at least partially mediated by sexual esteem, across both gender and sexual orientation. The findings suggest that, regardless of gender or sexual orientation, individuals who maintain a positive genital self-image or lack genital self-consciousness, are more likely to experience greater sexual esteem, and in turn, feel more sexually attractive. The findings have implications for the importance of genital appearance perceptions and improving individuals' sexual esteem and self-perceived sexual attractiveness.

    Full Text Available Ulcus vulvae acutum is a rare clinical condition characterized by the presence of multiple acute painful genital ulcers of non-venereal origin associated with systemic symptoms in young women. The aetiopathogenesis of the disease is not fully understood, although recent reports have associated it with the Epstein–Barr virus. Diagnosis is difficult and generally made by exclusion after venereal diseases, and autoimmune, inflammatory, traumatic, and neoplastic causes. We describe a case of adolescent female with an episode of ulcus vulvae acutum associated with infectious mononucleosis. The diagnosis was supported by the clinical symptoms, elevated circulating levels of liver enzymes, positive EBV serology, cervical and inguinal lymphadenomegaly, and hepatosplenomegaly. The patient presented a history of aphthous stomatitis. Negative Pathergy test and the absence of any other related symptoms allowed us to exclude the Behçhet syndrome. Lesions healed with no sequelae or recurrences.

    2014-05-01

    According to several sources, little progress is being made in eliminating the cutting of female genitalia. This paper, based on qualitative interviews and observations, explores perceptions of female genital cutting and elimination of the phenomenon in Hargeisa, Somaliland. Two main groups of participants were interviewed: (1) 22 representatives of organisations whose work directly relates to female genital cutting; and (2) 16 individuals representing different groups of society. It was found that there is an increasing use of medical staff and equipment when a girl undergoes the procedure of female genital cutting; the use of terminology is crucial in understanding current perceptions of female genital cutting; religion is both an important barrier and facilitator of elimination; and finally, traditional gender structures are currently being challenged in Hargeisa. The findings of this study suggest that it is important to consider current perceptions on practices of female genital cutting and on abandonment of female genital cutting, in order to gain useful knowledge on the issue of elimination. The study concludes that elimination of female genital cutting is a multifaceted process which is constantly negotiated in a diversity of social settings.

Orolabial and genital herpes are common disorders that can often be managed in an outpatient setting; however, some patients do present to the emergency department with those conditions, and emergency clinicians should be aware of possible complications in the pediatric population. Neonatal herpes is a rare disorder, but prompt recognition and initiation of antiviral therapy is imperative, as the morbidity and mortality of the disease is high. Herpes encephalitis is an emergency that also requires a high index of suspicion to diagnose. Herpes simplex virus is also responsible for a variety of other clinical presentations, including herpes gladiatorum, herpetic whitlow, eczema herpeticum, and ocular herpes. This issue reviews the common clinical presentations of the herpes simplex virus, the life-threatening infections that require expedient identification and management, and recommended treatment regimens.

    Genital ulcer disease by virtue of disruption of the mucosal surfaces may enhance HIV acquisition. Genital ulcer disease treatment with resolution of the ulcers may therefore contribute in reducing the sexual acquisition of HIV. To determine the effects of treatment of genital ulcer disease on sexual acquisition of HIV. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, LILACS, NLM Gateway, Web of Science, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, and reference lists of relevant publications for eligible studies published between 1980 and August 2011. Randomized controlled trials of any treatment intervention aimed at curing genital ulcer disease compared with an alternative treatment, placebo, or no treatment. We included only trials whose unit of randomization was the individual with confirmed genital ulcer. We independently selected studies and extracted data in duplicate; resolving discrepancies by discussion, consensus, and arbitration by third review author. We expressed study results as risk ratios (RR) with 95% confidence intervals (CI). There were three randomized controlled trials that met our inclusion criteria recruited HIV-negative participants with chancroid (two trials with 143 participants) and primary syphilis (one trial with 30 participants). The syphilis study, carried out in the US between 1995 and 1997, randomized participants to receive a single 2.0 g oral dose of azithromycin (11 participants); two 2.0 g oral doses of azithromycin administered six to eight days apart (eight participants); or benzathine penicillin G administered as either 2.4 million units intramuscular injection once or twice seven days apart (11 participants). No participant in the trial seroconverted during 12 months of follow-up. The chancroid trials, conducted in Kenya by 1990, found no significant differences in HIV seroconversion rates during four to 12 weeks of follow-up between 400 and 200 mg single

    Full Text Available Background: Trichomonas vaginalis (T.vaginalis and Neisseria gonorrhoeae (N.gonorrhoeae are two most common non-viral sexually transmitted infections in the world. No data are available regarding the epidemiology of genital infections in women of Qom, central Iran. Objective: Epidemiological investigation of sexually transmitted infections in genital specimens of women referred to the referral gynecology hospital in Qom, central Iran. Materials and Methods: Genital swab specimens were collected from women volunteers and used for identification of bacterial and protozoal infections by conventional microbial diagnostics, porA pseudo gene LightCycler® real-time PCR (for N.gonorrhoeae and ITS-PCR (for T.vaginalis. Results: Of 420 volunteers, 277 (65.9% had genital signs/symptoms, including 38.3% malodorous discharge, 37.9% dyspareunia, and 54.8% abdominal pain. Totally, 2 isolates of Streptococcus agalactiae were identified. Five specimens (1.2% in Thayer-Martin culture and 17 (4.1% in real-time PCR were identified as N.gonorrhoeae. Fifty-four specimens (12.9% in wet mount, 64 (15.2% in Dorset’s culture, and 81 (19.3% in ITS-PCR showed positive results for T.vaginalis. Five mixed infections of T.vaginalis+ N.gonorrhoeae were found. The risk of T.vaginalis infection was increased in women with low-birth-weight (p=0.00; OR=43.29, history of abortion (p=0.00; OR=91.84, and premature rupture of membranes (PROM (p=0.00; OR=21.75. The probability of finding nuclear leukocytes (p=0.00; OR=43.34 in vaginal smear was higher in T.vaginalis infection. Conclusion: The significant prevalence of trichomoniasis and gonorrhea emphasizes the need for accurate diagnosis and effective surveillance to prevent serious reproductive complications in women.

    In human genital skin the majority of superficial sensory corpuscles is represented by glomerular corpuscles. These corpuscles show an own morphology. Our aim is to compare the ultra-structure of superficial sensory corpuscles in the penis skin of younger and older subjects. In this report the ultra-structure of the sensitive corpuscle in the penis skin of the younger and older subjects was compared, showing that the genital skin of the older humans contains more simple complexes than the younger ones. Our findings support the view that the age-related changes that can be observed in human glomerular genital corpuscles are consistent with an increase of the simple complexes and a strong decrease of the poly-lamellar one in the older people. These findings demonstrate that human genital corpuscles underwent age-related changes. Moreover our morphological findings can be correlated in relation to the clinical evolution of the sensitivity in the genital skin.

    The female genital tract (FGT) microbiome may affect vaginal pH and other factors that influence drug movement into the vagina. We examined the relationship between the microbiome and antiretroviral concentrations in the FGT. Over one menstrual cycle, 20 human immunodeficiency virus (HIV)-infected women virologically suppressed on tenofovir (TFV) disoproxil fumarate/emtricitabine and ritonavir-boosted atazanavir (ATV) underwent serial paired cervicovaginal and plasma sampling for antiretroviral concentrations using high-performance liquid chromatography-tandem mass spectrometry. Analysis of 16S ribosomal RNA gene sequencing of cervicovaginal lavage clustered each participant visit into a unique microbiome community type (mCT). Participants were predominantly African American (95%), with a median age of 38 years. Cervicovaginal lavage sequencing (n = 109) resulted in a low-diversity mCT dominated by Lactobacillus (n = 40), and intermediate-diversity (n = 28) and high-diversity (n = 41) mCTs with abundance of anaerobic taxa. In multivariable models, geometric mean FGT:plasma ratios varied significantly by mCT for all 3 drugs. For both ATV and TFV, FGT:plasma was significantly lower in participant visits with high- and low-diversity mCT groups (all P < .02). For emtricitabine, FGT:plasma was significantly lower in participant visits with low- vs intermediate-diversity mCT groups (P = .002). Certain FGT mCTs are associated with decreased FGT antiretroviral concentrations. These findings are relevant for optimizing antiretrovirals used for biomedical HIV prevention in women. © The Author 2017.

    Genital herpes simplex virus (HSV) infection is a prevalent sexually transmitted infection. Vertical transmission of HSV can lead to fetal morbidity and mortality. To assess the evidence on serologic screening and preventive interventions for genital HSV infection in asymptomatic adults and adolescents to support the US Preventive Services Task Force for an updated recommendation statement. MEDLINE, Cochrane Library, EMBASE, and trial registries through March 31, 2016. Surveillance for new evidence in targeted publications was conducted through October 31, 2016. English-language randomized clinical trials (RCTs) comparing screening with no screening in persons without past or current symptoms of genital herpes; studies evaluating accuracy and harms of serologic screening tests for HSV-2; RCTs assessing preventive interventions in asymptomatic persons seropositive for HSV-2. Dual review of abstracts, full-text articles, and study quality; pooled sensitivities and specificities of screening tests using a hierarchical summary receiver operating characteristic curve analysis when at least 3 similar studies were available. Accuracy of screening tests, benefits of screening, harms of screening, reduction in genital herpes outbreaks. A total of 17 studies (n = 9736 participants; range, 24-3290) in 19 publications were included. No RCTs compared screening with no screening. Most studies of the accuracy of screening tests were from populations with high HSV-2 prevalence (greater than 40% based on Western blot). Pooled estimates of sensitivity and specificity of the most commonly used test at the manufacturer's cutpoint were 99% (95% CI, 97%-100%) and 81% (95% CI, 68%-90%), respectively (10 studies; n = 6537). At higher cutpoints, pooled estimates were 95% (95% CI, 91%-97%) and 89% (95% CI, 82%-93%), respectively (7 studies; n = 5516). Use of this test at the manufacturer's cutpoint in a population of 100 000 with a prevalence of HSV-2 of 16% (the

    This manuscript describes the male genital tract microbiota and the significance of it on the host's and his partner's health. Microbiota exists in male lower genital tract, mostly in urethra and coronal sulcus while high inter-subject variability exists. Differences appear between sexually transmitted disease positive and negative men as well as circumcised and uncircumcised men. Upper genital tract is generally germ-free, except in case of infections. Prostatitis patients have frequently abundant polymicrobial communities in their semen, expressed prostatic secretion and/or post-massage urine. Coryneform bacteria have ambivalent role in male urogenital tract being frequently commensals but sometimes associated with prostatitis and urethritis. Interactions between male and female genital tract microbiota are highly likely yet there are very scarce studies on the couples' genital tract microbiota. Increase of bacterial vaginosis-type microbiota and coliforms are the most typical findings in men while the adverse effect of male genital tract bacteria on in vitro fertilization and pregnancy outcome has also been indicated.

    Inflammatory mediators that weaken and cause membrane rupture are released during the course of genital infections among pregnant women. We set out to determine the association of common genital infections (Trichomonas vaginalis, syphilis, Neisseria gonorrhea, Chlamydia trachomatis, Group B Streptococcus, Bacterial vaginosis, Herpes Simplex Virus Type 2 and candidiasis) and premature rupture of membranes in Mulago hospital, Uganda. We conducted an unmatched case-control study among women who were in the third trimester of pregnancy at New Mulago hospital, Uganda. The cases had PROM and the controls had intact membranes during latent phase of labour in the labour ward. We used interviewer-administered questionnaires to collect data on socio-demographic characteristics, obstetric and medical history. Laboratory tests were conducted to identify T. vaginalis, syphilis, N. gonorrhea, C. trachomatis, Group B Streptococcus, Bacterial vaginosis, Herpes Simplex Virus Type 2 (HSV-2) and candidiasis. Logistic regression models were used to estimate the odds ratios (OR) and 95% CI of the association between genital infections and PROM. There was an association between PROM and abnormal vaginal discharge (OR = 2.02, 95% CI 1.10-3.70 and AOR = 2.30, 95% CI 1.18-4.47), presence of candidiasis (OR = 0.27, 95% CI 0.14-0.52 and AOR = 0.22, 95% CI 0.10-0.46) and T. vaginalis (OR = 2.98, 95% CI 1.18-7.56 and AOR = 4.22, 95% CI 1.51-11.80). However, there was no association between PROM and presence of C. trachomatis (OR = 2.05, 95% CI 0.37-11.49) and HSV-2 serostatus (OR = 1.15, 95% CI 0.63-2.09). Few or no patients with Bacterial vaginosis, Neisseria gonorrhoea, Group B streptococcus or syphilis were identified among the cases and controls. Co-infection of Trichomoniasis and candidiasis was not associated with PROM (AOR = 1.34, 95% CI 0.16-11.10). Co infection with T. vaginalis and C. trachomatis was associated with PROM (OR = 3.09, 95% CI 1.21-7.84 and AOR = 4.22, 95% CI 1

    Interleukin-8 (IL-8, CXCL8) plays important roles in immune responses at mucosal sites including in the lower genital tract. Since several types of bacteria produce proteases that cleave IL-8 and many types of bacteria can be present in lower genital tract microbiota, we assessed genital fluids for IL-8 cleavage/alteration. Genital fluids collected by lavage from 200 women (23 HIV-seronegative and 177 HIV-seropositive) were tested for IL-8 cleavage/alteration by ELISA. IL-8 cleaving/altering activity was observed in fluids from both HIV-positive (28%) and HIV-negative women (35%). There was no clear relationship between the activity and the types of bacteria present in the lower genital tract as determined by high-throughput sequencing of the 16S rRNA gene. Protease inhibitors specific for matrix metalloproteinases (MMPs) reduced the activity and a multiplex assay that detects both inactive and active MMPs showed the presence of multiple MMPs, including MMP-1, -3, -7, -8, -9, -10 and -12 in genital secretions from many of the women. The IL-8-cleaving/altering activity significantly correlated with active MMP-9 as well as with cleavage of a substrate that is acted on by several active MMPs. These studies show that multiple MMPs are present in the genital tract of women and strongly suggest that MMP-9 in genital secretions can cleave IL-8 at this mucosal site. These studies suggest that MMP-mediated cleavage of IL-8 can modulate inflammatory responses in the lower genital tract.

    To assess the perceptions of healthy men of their genital anatomy and sexual sensitivity, along with the re-test reliability of these ratings, in a new self-reported questionnaire, the Self-Assessment of Genital Anatomy and Sexual Function, Male (SAGASF-M). Eighty-one healthy, sexually active, men aged 22-57 years (median 33), with no history of genital surgery, completed the SAGASF-M. This questionnaire comprises written text and images enabling men to rate details of their genital appearance, overall genital erotic and pain sensitivity, orgasm intensity, and effort required for achieving orgasm through stimulation of specified areas around the glans and shaft of the penis, scrotum and anus, along with the contribution of other sexually sensitive areas of the body. Anatomical locations were compared for the functional ratings by mixed-model analysis of variance (anova). A second sample of 38 healthy men (median age 26 years, range 22-64) from the same source completed the SAGASF-M twice with an interval of 2 weeks. There was little variability in anatomy ratings. Ratings of overall penile sensitivity to sexual stimulation gave higher values of 'sexual pleasure' for penile stimulation by the partner than by self (P = 0.002) and marginally higher ratings of 'orgasm intensity' by partner stimulation (P = 0.077), but there were no corresponding differences on ratings of 'effort needed to reach orgasm' or of 'discomfort/pain'. Overall discrimination between genital areas was highly significant (mixed-model anova, P = 0.001) for ratings of 'sexual pleasure', 'orgasm intensity' and 'orgasm effort', but was not significant for 'discomfort/pain'. Ranked by degree of 'sexual pleasure', the area 'underside of the glans' was highest, followed by 'underside of the penile shaft', 'upper side of the glans', 'left and right sides of the glans', 'one or both sides of the penis', 'upper side of the penile shaft', 'foreskin' (11 subjects), 'skin between the scrotum and anus', 'back

    Animals with internal fertilization often exhibit marked diversification in genital morphology among closely related species. However, our knowledge of the genetic architecture underlying genital evolution is still limited. We constructed genetic linkage maps and analysed quantitative trait loci (QTL) for F(2) hybrids of two closely related species of the carabid beetles Carabus (Ohomopterus) iwawakianus and C. (O.) maiyasanus, which show matching male and female genital shapes within species, but marked differences in genital morphologies between species. The linkage maps comprised both amplified fragment length polymorphism and microsatellite markers. Composite interval mapping to detect QTL for three traits of male copulatory piece (length, width, weight) and two traits for female vaginal appendix (length, width) resulted in the detection of one to five significant QTL for each trait. The QTL explained large proportions of phenotypic variance. Thus, the interspecific difference in the genital morphologies appeared to be determined by relatively small numbers of genes with large genetic effects. QTL of different traits for the same or different sexes co-occurred on five of eight linkage groups with significant QTL; in particular, three QTL for different male and female genital traits occurred almost at the same position. Each of the male genital traits showed uniform signs of additive genetic effects, suggesting that directional selection has led to species-specific morphologies. However, the signs of additive genetic effects in each female genital trait were not uniform, suggesting that coevolution between sexes is not necessarily concerted. This result requires further assessment because the sample size of F(2) females was small. © 2010 Blackwell Publishing Ltd.

    2012-01-01

    Full Text Available Background. Lichen Planus is a chronic mucocutaneous disease of immunological basis and unknown etiology. women with oral lichen planus may have concomitant manifestations in vulvovaginal areas. Objective. To determine the frequency and risk factors of genital involvement in a group of Iranian women affected by oral lichen planus. Methods. Thirty-six women with clinical and histopathological diagnosis of oral lichen planus were evaluated for demographic, historical, and clinical parameters of the oral disease. All the patients were referred for careful vulvovaginal examination, as well as histopathological assessment upon clinical indication. Results. Nineteen patients complained from genital symptoms but the number of women with the final diagnosis of genital lichen planus (=2 was too small to show any correlation with the parameters evaluated. Conclusion. In spite of low genital involvement possibly due to inadequate patient population, lack of follow-up visits, and contribution of genetic or ethnic factors, for conservative patient care, women with the oral lichen planus in particular those having some relevant genital symptoms, should preferably be referred for careful vulvovaginal examination. Multicenter cohort studies on women of different geographical regions or ethnicities who have genital lichen planus alone or in combination with other common sites are encouraged.

    Heinonen, Pentti K

    2016-11-01

    This study assessed the distribution of Müllerian duct anomalies in two verified classifications of female genital tract malformations, and the presence of associated renal defects. 621 women with confirmed female genital tract anomalies were retrospectively grouped under the European (ESHRE/ESGE) and the American (AFS) classification. The diagnosis of uterine malformation was based on findings in hysterosalpingography, two-dimensional ultrasonography, endoscopies, laparotomy, cesarean section and magnetic resonance imaging in 97.3% of cases. Renal status was determined in 378 patients, including 5 with normal uterus and vagina. The European classification covered all 621 women studied. Uterine anomalies without cervical or vaginal anomaly were found in 302 (48.6%) patients. Uterine anomaly was associated with vaginal anomaly in 45.2%, and vaginal anomaly alone was found in 26 (4.2%) cases. Septate uterus was the most common (49.1%) of all genital tract anomalies, followed by bicorporeal uteri (18.2%). The American classification covered 590 (95%) out of the 621 women with genital tract anomalies. The American system did not take into account vaginal anomalies in 170 (34.7%) and cervical anomalies in 174 (35.5%) out of 490 cases with uterine malformations. Renal abnormalities were found in 71 (18.8%) out of 378 women, unilateral renal agenesis being the most common defect (12.2%), also found in 4 women without Müllerian duct anomaly. The European classification sufficiently covered uterine and vaginal abnormalities. The distribution of the main uterine anomalies was equal in both classifications. The American system missed cervical and vaginal anomalies associated with uterine anomalies. Evaluation of renal system is recommended for all patients with genital tract anomalies.

    The objective was to determine the contribution of female genital cutting to genital fistula formation in Niger from the case records of a specialist fistula hospital. A retrospective review was undertaken of the records of 360 patients seen at the Danja Fistula Center, Danja, Niger, between March 2014 and September 2016. Pertinent clinical and socio-demographic data were abstracted from the cases identified. A total of 10 fistulas resulting from gurya cutting was obtained: 9 cases of urethral loss and 1 rectovaginal fistula. In none of the cases was genital cutting performed for obstructed labor or as part of ritual coming-of-age ceremonies, but all cutting procedures were considered "therapeutic" within the local cultural context as treatment for dyspareunia, lack of interest in or unwillingness to engage in sexual intercourse, or female behavior that was deemed to be culturally inappropriate by the male spouse, parents, or in-laws. Clinical cure (fistula closed and the patient continent) was obtained in all 10 cases, although 3 women required more than one operation. Gurya cutting is an uncommon, but preventable, cause of genital fistulas in Niger. The socio-cultural context which gives rise to gurya cutting is explored in some detail.

    1999-01-01

    A polymerase chain reaction (PCR) assay was developed for detecting duck plague virus. A 765-bp EcoRI fragment cloned from the genome of the duck plague vaccine (DP-VAC) virus was sequenced for PCR primer development. The fragment sequence was found by GenBank alignment searches to be similar to the 3a?? ends of an undefined open reading frame and the gene for DNA polymerase protein in other herpesviruses. Three of four primer sets were found to be specific for the DP-VAC virus and 100% (7/7) of field isolates but did not amplify DNA from inclusion body disease of cranes virus. The specificity of one primer set was tested with genome templates from other avian herpesviruses, including those from a golden eagle, bald eagle, great horned owl, snowy owl, peregrine falcon, prairie falcon, pigeon, psittacine, and chicken (infectious laryngotracheitis), but amplicons were not produced. Hence, this PCR test is highly specific for duck plague virus DNA. Two primer sets were able to detect 1 fg of DNA from the duck plague vaccine strain, equivalent to five genome copies. In addition, the ratio of tissue culture infectious doses to genome copies of duck plague vaccine virus from infected duck embryo cells was determined to be 1:100, making the PCR assay 20 times more sensitive than tissue culture for detecting duck plague virus. The speed, sensitivity, and specificity of this PCR provide a greatly improved diagnostic and research tool for studying the epizootiology of duck plague. /// Se desarroll?? una prueba de reacci??n en cadena por la polimerasa para detectar el virus de la peste del pato.

    Full Text Available During 1983-86, 225 patients were clinically diagnosed to have genital herpes (GH at our clinic. Of these, 90 men and 55 women were currently married. All the spouses were screened clinically and through standardized techniques for isolation and typing of herpes simplex virus, serological testing and Papanicolaou smear. There were 90 couples in whom at least one spouse had GH and in 38 (42% couples both partners had GH. Clinically, 49% of wives and 75% of husbands of GH patients were diagnosed to have the disease. The spouses of recurrent GH patients had a higher frequency of the disease than spouses of primary GH patients. Among spouses who were clinically asymptomatic, 40% had high serological titres suggestive of GH. Wives generally experienced more severe symptoms, especially pain in the lesions. Majority of lesions in both the partners were vesicles and ulcers. Prodromata were more among recurrent GH patients in both the partners. The frequency of recurrences wasalso similar in spouses. Seventy percent of wives and 40% of husbands could not identify any precipitating factor. Intercourse, physical stress and rich food were cited as possible factors in the remaining. All the wives had acquired the diseases through their husbands who were promiscuous. Fifty percent of husbands had been infected before marriage. Given the fact that asymptomatic carriers exist, it is better to consider all marital partners of GH as infected. Repeated and long-term follow, - up examination, particularly of wives of GH patients is therefore essential as an important socio-preventive aspect of this disease.

    "Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy. © 2015 Elsevier B.V.

    1983-01-01

    Six women who underwent radiation therapy for gynecologic malignancies demonstrated cytologic evidence of condyloma virus infection 2 or more years following radiation. Histologic confirmation was obtained in two of the cases. A seventh patient developed in situ and invasive squamous cell carcinoma in a vulvar condyloma acuminatum following radiation therapy for Hodgkin's disease. This venereal infection is found most frequently in sexually active younger women (average age, 27 years). It is felt that depressed cell-mediated immunity consequent to the radiation therapy allowed the development of this infection in the older patients described in this report. The evolution of invasive squamous cell carcinoma in the condyloma acuminatum may indicate a possible oncogenic or cocarcinogenic effect of the virus. The immunologic responses to infection caused by the human papillomavirus group are discussed, as well as its potential for malignant transformation

    Full Text Available El principal factor que interviene en el origen y prevención de las enfermedades trasmitidas por los alimentos es la higiene alimentaria. Dichas enfermedades son causadas por la ingestión de alimentos o agua contaminados con microorganismos patógenos ocasionando una infección o por la ingestión de alimentos contaminados con toxinas. Los principales agentes involucrados son Escherichia Coli, Campylobacter, Salmonella, Shigella, Listeria Monocytogenes, Norovirus, virus Hepatitis A, Astrovirus, Rotavirus, y Virus Coxsackie. Toxinas producidas por hongos o por microflora marina y los contaminantes orgánicos persistentes pueden también causar serios problemas de salud. La inocuidad alimentaría ha tomado relevancia debido a una mayor exigencia por consumidores cada día más informados y por las demandas del comercio exterior. Medidas que aseguren una adecuada higiene alimentaría nos permitirá prevenir enfermedades, principalmente digestivas, causadas por variados agentes en los alimentos. Esto se logra por la implementación de las medidas propuestas por la Comisión Internacional conocida como Codex Alimentarius.

  20. STING agonists enable antiviral cross-talk between human cells and confer protection against genital herpes in mice.

    In recent years, there has been an increasing interest in immunomodulatory therapy as a means to treat various conditions, including infectious diseases. For instance, Toll-like receptor (TLR) agonists have been evaluated for treatment of genital herpes. However, although the TLR7 agonist imiquimod was shown to have antiviral activity in individual patients, no significant effects were observed in clinical trials, and the compound also exhibited significant side effects, including local inflammation. Cytosolic DNA is detected by the enzyme cyclic GMP-AMP (2'3'-cGAMP) synthase (cGAS) to stimulate antiviral pathways, mainly through induction of type I interferon (IFN)s. cGAS is activated upon DNA binding to produce the cyclic dinucleotide (CDN) 2'3'-cGAMP, which in turn binds and activates the adaptor protein Stimulator of interferon genes (STING), thus triggering type I IFN expression. In contrast to TLRs, STING is expressed broadly, including in epithelial cells. Here we report that natural and non-natural STING agonists strongly induce type I IFNs in human cells and in mice in vivo, without stimulating significant inflammatory gene expression. Systemic treatment with 2'3'-cGAMP reduced genital herpes simplex virus (HSV) 2 replication and improved the clinical outcome of infection. More importantly, local application of CDNs at the genital epithelial surface gave rise to local IFN activity, but only limited systemic responses, and this treatment conferred total protection against disease in both immunocompetent and immunocompromised mice. In direct comparison between CDNs and TLR agonists, only CDNs acted directly on epithelial cells, hence allowing a more rapid and IFN-focused immune response in the vaginal epithelium. Thus, specific activation of the STING pathway in the vagina evokes induction of the IFN system but limited inflammatory responses to allow control of HSV2 infections in vivo.

  1. The presentation and management of complex female genital malformations.

    Common uterine anomalies are important owing to their impact on fertility, and complex mesonephric anomalies and certain Müllerian malformations are particularly important because they cause serious clinical symptoms and affect woman's quality of life, in addition to creating fertility problems. In these cases of complex female genital tract malformations, a correct diagnosis is essential to avoid inappropriate and/or unnecessary surgery. Therefore, acquiring and applying the appropriate embryological knowledge, management and therapy is a challenge for gynaecologists. Here, we considered complex malformations to be obstructive anomalies and/or those associated with cloacal and urogenital sinus anomalies, urinary and/or extragenital anomalies, or other clinical implications or symptoms creating a difficult differential diagnosis. A diligent and comprehensive search of PubMed and Scopus was performed for all studies published from 1 January 2011 to 15 April 2015 (then updated up to September 2015) using the following search terms: 'management' in combination with either 'female genital malformations' or 'female genital tract anomalies' or 'Müllerian anomalies'. The MeSH terms 'renal agenesis', 'hydrocolpos', 'obstructed hemivagina' 'cervicovaginal agenesis or atresia', 'vaginal agenesis or atresia', 'Herlyn-Werner-Wunderlich syndrome', 'uterine duplication' and 'cloacal anomalies' were also used to compile a list of all publications containing these terms since 2011. The basic embryological considerations for understanding female genitourinary malformations were also revealed. Based on our experience and the updated literature review, we studied the definition and classification of the complex malformations, and we analysed the clinical presentation and different therapeutic strategies for each anomaly, including the embryological and clinical classification of female genitourinary malformations. From 755 search retrieved references, 230 articles were analysed and

    Full Text Available Most HIV-infected individuals are coinfected by Herpes simplex virus type 2 (HSV-2. HSV-2 reactivates more frequently in HIV-coinfected individuals with advanced immunosuppression, and may have very unusual clinical presentations, including hypertrophic genital lesions. We report the case of a progressive, hypertrophic HSV-2 lesion in an HIV-coinfected woman, despite near-complete immune restoration on antiretroviral therapy for up to three years. In this case, there was prompt response to topical imiquimod. The immunopathogenesis and clinical presentation of HSV-2 disease in HIV-coinfected individuals are reviewed, with a focus on potential mechanisms for persistent disease despite apparent immune reconstitution. HIV-infected individuals and their care providers should be aware that HSV-2 may cause atypical disease even in the context of near-comlpete immune reconstitution on HAART.

    Herpes simplex encephalitis (HSE) is associated with significant mortality and morbidity. As a consequence of HSE, up to 75% of infected individuals die or experience irreversible neurological damage. While the pathogenesis of the disease is unknown, it is traditionally hypothesized that the viral infection occurs by neuronal transmission directly from peripheral sites. Non-neuronal modes of infection have generally been overlooked as the brain is protected by the blood-brain-barrier (BBB). The BBB poses an effective barrier to pathogens as well as to drugs such as chemotherapies. In the pursuit to deliver chemotherapeutic agents to the brain, several studies demonstrated that phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil, may increase the permeability of the BBB enabling successful delivery of chemotherapeutic agents to the brain. In this communication, we report a case of HSE infection in a 62-year-old man, which we suspect was facilitated by the use of sildenafil during a primary genital herpes simple virus (HSV) infection. Due to large number of patients treated with PDE5 inhibitors for erectile dysfunction and the high incidence of genital HSV infection in the general population, a larger study should examine the potential risk of developing HSE in patients treated with PDE5 inhibitors.

    Sexually transmitted diseases constitute major health issues and their prevention and treatment continue to challenge the health care systems worldwide. Animal models are essential for a deeper understanding of the diseases and the development of safe and protective vaccines. Currently a good predictive non-rodent model is needed for the study of genital chlamydia in women. The pig has become an increasingly popular model for human diseases due to its close similarities to humans. The aim of this review is to compare the porcine and human female genital tract and associated immune system in the perspective of genital Chlamydia infection. The comparison of women and sows has shown that despite some gross anatomical differences, the structures and proportion of layers undergoing cyclic alterations are very similar. Reproductive hormonal cycles are closely related, only showing a slight difference in cycle length and source of luteolysing hormone. The epithelium and functional layers of the endometrium show similar cyclic changes. The immune system in pigs is very similar to that of humans, even though pigs have a higher percentage of CD4(+)/CD8(+) double positive T cells. The genital immune system is also very similar in terms of the cyclic fluctuations in the mucosal antibody levels, but differs slightly regarding immune cell infiltration in the genital mucosa - predominantly due to the influx of neutrophils in the porcine endometrium during estrus. The vaginal flora in Göttingen Minipigs is not dominated by lactobacilli as in humans. The vaginal pH is around 7 in Göttingen Minipigs, compared to the more acidic vaginal pH around 3.5-5 in women. This review reveals important similarities between the human and porcine female reproductive tracts and proposes the pig as an advantageous supplementary model of human genital Chlamydia infection.

  17. Male genital mutilation in the high-mountain goblin spider, Unicorn catleyi.

    Izquierdo, Matías A; Rubio, Gonzalo D

    2011-01-01

    Male genital mutilation is a common mechanism by which males reduce sperm competition by plugging female insemination ducts with different parts of its own genital system. This behavior is frequent in many spider families but is uncommon in Haplogynae. The reproductive biology of Dysderoidea is not well studied and the data is fragmentary; male genital mutilation has been reported only for one species of Oonopidae. This study provides evidence of male genital mutilation in Unicorn catleyi Platnick and Brescovit (Araneae: Oonopidae). Pieces of the embolus were found in the female posterior receptaculum. This behavior is a strategy used by the males in order to guarantee their paternity and not for escape from female attacks as has been reported for other species of Araneae, since cannibalism is unlikely in this species. The presence of embolus in the posterior receptaculum suggests this is the first place where sperm is received. The similarity of the female genitalia of U. catleyi to those of Orsolobidae, along with sclerotization of the seminal duct in the male copulatory bulb that is also present in Orchestina, Xiombarg, and Orsolobidae, provide strong evidence of the basal position of this genus in the family Oonopidae.

    1999-01-01

    There is increasing interest in the use of topical microbicides to help prevent the spread of sexually transmitted diseases (STD). Undecylenic acid (UA), a monosaturated fatty acid, is the active ingredient in a number of over-the-counter (OTC) antifungal spray powders, that also exhibits in vitro antibacterial and antiviral activity, including herpes simplex virus (HSV) activity. We, therefore, evaluated UA as a topical microbicide against genital HSV infection using the murine and guinea pig models of genital herpes. Mice were administered a 20% solution of UA in polyethylene glycol (PEG) vehicle, vehicle alone or phosphate buffered saline (PBS) intravaginally immediately prior to vaginal challenge with HSV-2. Pre-treatment with UA decreased the number of mice that became infected (P < 0.001 vs. PBS or vehicle control), developed symptoms (P <0.001) or died (P <0.001). However, when treatment was extended to either 5 min prior to or after viral inoculation, protection was lost. Similar findings were found using the guinea pig model, where UA treatment completely prevented HSV-2 vaginal infection when given immediately prior to HSV-2 inoculation (P<0.001 vs. PBS or vehicle control). Thus, UA, an approved OTC medication, provided significant protection against HSV disease and infection only when applied immediately before viral inoculation, indicating that better formulations were needed to extend the duration of protection.

    To describe pattern of female genital tract cancers seen at Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Nigeria. This is a retrospective review of all cases of female genital tract cancers managed at the Gynaecology department of OOUTH, Sagamu, Nigeria. OOUTH is a tertiary health institution of the State's university and it takes referrals from within and outside the State. Case records of all female genital tract cancers managed between January 2004 and December 2013 were retrieved and analysed using SPSS version 16.0. There were 2059 women treated forvarious gynaecologic conditions, 179 (8.7%) were cases of female genital tract cancers and 161 records were available for analysis. Cervical cancer constituted the commonest (51.6%), followed by ovarian (35.4%), endometrial (9.9%), and choriocarcinoma (1.9%). There were no cases of vaginal and fallopian tube cancers. The lowest mean age was found in choriocarcinoma (36.60 ± 4.50 years) and highest in vulvar cancer (70.00 ± 2.82 years). The mean ages for cervical, endometrial and ovarian cancers were (51.98 ± 12.39), (65.38 ± 7.24), and (54.42 ± 10.51) years respectively. Similarly the least mean parity was found in choriocarcinoma (2.33 ± 1.52), and the highest in vulvar cancer (6.00 ± 1.44). The mean parity for cervical, endometrial, and ovarian were (4.10 ± 1.49),(3.06 ± 1.48), and (3.72 ± 1.68) respectively. These differences are statistically significant, age; F = 7.61, p < 0.0001, and parity; F = 3.27, p= 0.013. Incidence of cervical, endometrial, and ovarian cancers remain high and presentations are at late stages. There is a need to improve on cervical cancer screening, and for the attending physicians to improve on their indices of suspicions as regards endometrial and ovarian cancers.

    To determine the frequency and pattern of malignant tumours of the female genital tract among Batswana women. A four-year retrospective histological study of the pattern of female genital tract malignancy in Botswana. University of Botswana and the National Health Laboratory Gaborone, Botswana. The National Health Laboratory is the only public tertiary referral laboratory that provides diagnostic pathology services in the South-Eastern part of Botswana. It is located just adjacent to Princess Marina Hospital, the major tertiary referral hospital in the country. All histologically confirmed diagnoses of female genital tract malignancies from January 1st 2006 to December 31st 2009 were reviewed by two pathologists and diagnoses re-confirmed by taking fresh tissue sections from paraffin embedded archival tissue blocks. The age of patients ranged from 13-96 years with a mean age of 54.5 ± 6.4 years. Cancer of the cervix constituted 80.6%, followed by uterine cancer (10.0%), carcinomas of the vulva (4.5%) and ovary (3.4%) in that order. Ovarian cancers predominated in the younger age group. There was a steady increase in the frequencies of cervical, uterine and ovarian cancers over the 4-year study period with a decline in uterine cancer in the 4th year. Cervical cancer incidence is high among Batswana women and all female genital tract cancers occurred at a relatively early mean age. Therefore the importance of established and accessible screening programs and awareness campaigns need more emphasis than it is being given currently. (au)

    Full Text Available The anatomical characteristics, and the ovarian and pathological structures of the genital tract of 500 zebu (Bos indicus females belonging to four breeds (Azawak, Bororo, Djelli, Goudali were studied at Niamey’s slaughterhouse in Niger from August 15 to December 15, 2011. Each animal was examined before slaughter. The cows and heifers were on average 8 ± 2.5 years old. Their mean body condition score was 1.6 ± 0.6 and mean carcass weight 113 ± 21 kg. The anatomical characteristics of the genital tract did not show differences between breeds (p > 0.05. The following characteristics were observed: cervix diameter 3.4 ± 1.1 cm, cervix length 8.1 ± 2.5 cm, horn length 21.6 ± 5.2 cm, horn diameter 1.6 ± 0.5 cm, length and width of the right ovary 19.8 ± 4.4 and 11.2 ± 3.8 mm, of the left ovary 18.8 ± 4.5 and 10.2 ± 3.3 mm, and weight of the right and left ovaries 2.9 ± 1.8 and 2.5 ± 1.6 g, respectively. A corpus luteum was identified in only 14% cases and no visible follicles were found on the surface of the ovaries in 32% cases. These characteristics were significantly (p < 0.05 influenced by the age of the animal. Among the examined females, 7.4% were confirmed pregnant.

    :  Feral swine ( Sus scrofa) are a pathogen reservoir for pseudorabies virus (PrV). The virus can be fatal to wildlife and contributes to economic losses in the swine industry worldwide. National surveillance efforts in the US use serology to detect PrV-specific antibodies in feral swine populations, but PrV exposure is not a direct indicator of pathogen transmission among conspecifics or to non-suid wildlife species. We measured antibody production and the presence of PrV DNA in four tissue types from feral swine populations of Florida, US. We sampled blood, nasal, oral, and genital swabs from 551 individuals at 39 sites during 2014-16. Of the animals tested for antibody production, 224 of 436 (51%) feral swine were antibody positive while 38 of 549 feral swine (7%) tested for viral shedding were quantitative polymerase chain reaction (qPCR)-positive for PrV. The detection of PrV DNA across all the collected sample types (blood, nasal, oral, and genital [vaginal] swabs) suggested viral shedding via direct (oronasal or venereal), and potentially indirect (through carcass consumption), routes of transmission among infected and susceptible animals. Fourteen of 212 seronegative feral swine were qPCR-positive, indicating 7% false negatives in the serologic assay. Our findings suggest that serology may underestimate the actual infection risk posed by feral swine to other species and that feral swine populations in Florida are capable of shedding the virus through multiple routes.

    A 24-year-old immune-competent woman was admitted to hospital with a three-day history of fever and headache. On examination bilateral facial nerve palsy, lumbosacral radicular pain, reduced sacral sensibility and urinary retention were found. Open perianal lesions were suspect for genital herpes. The symptoms were compatible with a meningoradiculitis including a sacral polyradiculitis. On testing, cerebrospinal fluid was found to be abnormal with a lymphocytic cell reaction. Polymerase chain reaction (PCR) of cerebrospinal fluid and of the perianal lesions was positive for herpes simplex virus type 2 (HSV-2). An MRI scan showed colouration of part of the cauda equina. The patient was treated by intravenous injections of acyclovir 10 mg/kg t.i.d. for 21 days, after which she completely recovered. HSV-2 infection of the nervous system can cause lymphocytic, and sometimes recurrent meningitis as well as sacral polyradiculitis. It may also occur without any symptomatic genital herpes infection. A positive result from a PCR test of the cerebrospinal fluid confirms this diagnosis. Treatment with acyclovir should be started as soon as possible.

    Full Text Available Fournier’s gangrene is a life-threatening disorder caused by aerobic and anaerobic bacterial infection. We report a case of genital infection as the initial warning sign of acute myeloid leukemia. We were able to prevent progression to Fournier’s gangrene in our patient by immediate intensive therapy with incision, blood transfusions and intravenous administration of antibiotics. This case suggests that hematologists and dermatologists should keep in mind that genital infection can be a first sign of hematologic malignancy.

    The interest and demand for female genital rejuvenation surgery are steadily increasing. This report presents a concept of genital beautification consisting of labia minora reduction, labia majora augmentation by autologous fat transplantation, labial brightening by laser, mons pubis reduction by liposuction, and vaginal tightening if desired. Genital beautification was performed for 124 patients between May 2009 and January 2012 and followed up for 1 year to obtain data about satisfaction with the surgery. Of the 124 female patients included in the study, 118 (95.2 %) were happy and 4 (3.2 %) were very happy with their postoperative appearance. In terms of postoperative functionality, 84 patients (67.7 %) were happy and 40 (32.3 %) were very happy. Only 2 patients (1.6 %) were not satisfied with the aesthetic result of their genital beautification procedures, and 10 patients (8.1 %) experienced wound dehiscence. The described technique of genital beautification combines different aesthetic female genital surgery techniques. Like other aesthetic surgeries, these procedures are designed for the subjective improvement of the appearance and feelings of the patients. The effects of the operation are functional and psychological. They offer the opportunity for sexual stimulation and satisfaction. The complication rate is low. Superior aesthetic results and patient satisfaction can be achieved by applying this technique. This journal requires that authors assign a level of evidence to each article.

    The experiences of special X-ray diagnostics of female genitals are described, that were made in 41 children within a period of 12 years. The superiority of the X-ray-technique arises from the impossibility of the manual examination in newborn and infants and the avoidance of diagnostic techniques like laparoscopy or laparotomy. All the examination techniques are described. In intersexualmarked patients the discrimination into six types after Shopfner is preferred. Malformations and tumours are dealt with briefly. The relations between skeleton and female genitals are pointed out at the example of the gonadal dysgenesis. (orig.) [de

    About 27,000 women from countries in which female genital mutilation (FGM) is a common practice are presently living in Sweden. This means that FGM is a phenomenon that directly affects the Swedish health care system. Knowledge and understanding of the background, meaning and consequences of FGM are a prerequisite for effective prevention, proper clinical handling and supportive reception of the women. To avoid a stigmatizing reception it is also important to understand the situation of genitally mutilated women, and to become aware of the identity crisis many of them experience when they come to Sweden and lose their identity as "normal" women. It is essential to remember that female genital mutilation is one of many forms of discrimination affecting girls and women around the world. This discrimination knows no national or cultural borders and varies in expression and extent. In order to offer optimal care and reception of women who have been socialized into a gender role that is often seen as completely different from the gender role that Swedish society is said to embrace, it is of the utmost importance to first take a critical look beneath the veil of alleged gender equality of Swedish women.

    The prevalence of HPV infection in Latin America is among the highest in the world. A quadrivalent (types 6/11/16/18) human papillomavirus L1 virus-like-particle vaccine has been shown to be 95-100% effective in preventing HPV 6/11/16/18-related cervical and genital disease in women naive to vaccine HPV types. A total of 6,004 female subjects aged 9-24 were recruited from Brazil, Mexico, Colombia, Costa Rica, Guatemala and Peru. Subjects were randomized to immunization with intramuscular (deltoid) injections of HPV vaccine or placebo at enrollment (day 1), month 2 and month 6. Among vaccinated subjects in the per-protocol population from Latin America, quadrivalent HPV vaccine was 92.8 and 100% effective in preventing cervical intraepithelial neoplasia and external genital lesions related to vaccine HPV types, respectively. These data support vaccination of adolescents and young adults in the region, which is expected to greatly reduce the burden of cervical and genital cancers, precancers and genital warts.

    1995-12-01

    This review presents and discusses the reasons for the currently employed anatomical terminology relating to the genital peritoneum of various domestic species, based upon its prenatal development. When reviewing the development of genital organs, attention must be paid to changes in the related peritoneum in order to define currently used terminology more clearly. The relevance of some terms such as Caudal genital ligament, Plica gubernaculi, Plica iguinalis and genital fold is considered. A system of serosal folds, the Plica gonadoinguinalis or genitoinguinalis, seems to be a useful term to be added to the Nomina Embryologica Veterinaria.

    Full Text Available Abstract Background Epidemiological studies on genital human papilloma viruses infection (HPVs in general population are crucial for the implementation of health policy guidelines for developing the strategies to prevent the primary and secondary cervical cancer. In different parts of Iran, there is a lack of population-based studies to determine the prevalence of HPV in the general population. The aim of this population-based study is to compare the prevalence rate of genital HPV infection among reproductive women with our previous clinic-based data, which showed a prevalence rate of 5% in women in southern Iran. Results Using general primers for all genotypes of HPV, of 799 randomly selected women, five (0.63%, 95% CI 0.23-1.55% tested positive for HPV DNA. Overall, seven different HPV genotypes were detected: six types (16, 18, 31, 33, 51 and 56 were carcinogenic, or “high risk genotypes” and one genotype (HPV-66 was “probably carcinogenic.” Conclusions In a population-based study, the prevalence of HPV infection among southern Iranian women was lower than that observed worldwide. However, our gynaecological clinic-based study on the prevalence of HPV infection showed results comparable with other studies in the Middle East and Persian Gulf countries. Since gynaecological clinic-based data may generally overestimate HPV prevalence, estimates of prevalence according to clinic-based data should be adjusted downward by the population-based survey estimates.

    Full Text Available Aim: The goal of the study was to determine external genital anomaly types in children attending primary school (6-15 years old in Sakarya. Material and Method: 1573, 6-15 years old student randomly selected from 8 schools inside the province. The students were examined in an appropriate room in the school, and external genital anomalies were identified and noted. Results: In this study, a total of 106 (6,7 % anomalies were identified in 1573 students. The most common anomalies were phimosis 3,6 % (56 and undescended testis 2,6 % (41. Discussion: This study shows that the ratio of the external genital anomaly that needs to be cured before primary school is high. Socioeconomic differences and environmental factors can affect anomaly prevalence. Health care workers all over the country should be trained regarding the issue. In addition to these, to identify genital anomalies before children start primary school, specific training programs should be prepared for parents.

    2014-01-01

    Full Text Available The most prevalent, curable sexually important diseases are those caused by Chlamydia trachomatis (C. trachomatis and genital mycoplasmas. An important characteristic of these infections is their ability to cause long-term sequels in upper genital tract, thus potentially affecting the reproductive health in both sexes. Pelvic inflammatory disease (PID, tubal factor infertility (TFI, and ectopic pregnancy (EP are well documented complications of C. trachomatis infection in women. The role of genital mycoplasmas in development of PID, TFI, and EP requires further evaluation, but growing evidence supports a significant role for these in the pathogenesis of chorioamnionitis, premature membrane rupture, and preterm labor in pregnant woman. Both C. trachomatis and genital mycoplasmas can affect the quality of sperm and possibly influence the fertility of men. For the purpose of this paper, basic, epidemiologic, clinical, therapeutic, and public health issue of these infections were reviewed and discussed, focusing on their impact on human reproductive health.

    Herpes simplex virus type 1 (HSV-1) is isolated principally from the upper half of the body innervated by the trigeminal ganglia whereas herpes simplex virus type 2 (HSV-2) is generally isolated from the lower half of the body innervated by the sacral ganglia. However, recent reports suggest that HSV-1 and HSV-2 can each infect both the upper and lower half of the body causing a variety of symptoms and there is a possibility that HSV-1 and HSV-2 infections can occur simultaneously with both causing symptoms. HSV type in clinical isolates from 87 patients with genital herpes and 57 with ocular herpes was determined by the polymerase chain reaction (PCR), and six cases of mixed infection with both HSV-1 and HSV-2 were identified. Of the six cases, three were patients with genital herpes and three were ocular herpes patients. Analysis of the copy number of the HSV-1 and HSV-2 genome by a quantitative real time PCR demonstrated that HSV-1 was dominant at a ratio of approximately 100:1 in the ocular infections. In contrast, the HSV-2 genome was present at a 4-40 times higher frequency in isolates from genital herpes patients. There was no obvious difference between the clinical course of mixed infection and those of single HSV-1 or HSV-2 infections. This study indicated that the frequency of mixed infection with both HSV-1 and HSV-2 is comparatively higher than those of previous reports. The genome ratio of HSV-1 and HSV-2 reflects the preference of each HSV type for the target organ.

    The immune protection of genital organs in embryogenesis has not been sufficiently studied. The purpose of this study was to investigate the development of the secretory immune system (SIS) in the gonads and genital tracts of human embryos and fetuses. Developing gonads at different stages and genital tracts from 18 embryos and 39 fetuses in the first to third trimester of gestation were analyzed for presence of different component of SIS: secretory component (SC), joining (J) chain. IgA, IgM, IgG, macrophages, and subsets of lymphocytes. The material was divided into two groups: cases not subjected to foreign antigenic effects (group I, n = 31) and those under antigenic attack (chorioamnionitis, group II, n = 26). In embryos and fetuses of group I, SC, J chain, and IgG were seen in the epithelium of mesonephric and paramesonephric ducts, proliferating coelomic epithelium, epithelium of the uterine tubes and uterus, epithelium of the vas deferens, epididymis, and rete testis. IgA and IgM appeared in 6-week-old embryos. J chain, IgA, IgM, and IgG, but not SC, were found in the primary oocytes and oogonia, spermatogonia. and interstitial cells. An abundance of macrophages was seen in 4-week-old embryos. T and B lymphocytes first appeared in 6-7-week-old embryos. In embryos and fetuses of group II, reactivity of immunoglobulins (Igs) decreased until they disappeared altogether. Components of SIS were seen in genital organs in 4-5-week-old embryos and were present during the whole intrauterine period. We suggest the presence of two forms of immune protection of fetal genital organs. One form contains SC, J chain, and Igs and is present in the genital tract epithelium. The second form contains only J chain and Igs and is present in germ cells of gonads. The loss of Igs in cases with chorioamnionitis reflects the functional participation of the SIS of genital organs in response to antigen attack.

    Bowen's disease (BD) is an epidermal in-situ squamous cell carcinoma (SCC). Most Human Papilloma Viruses (HPV)-positive lesions in Bowen's disease are localized to the genital region or distal extremities (periungual sites) in which HPV type-16 is frequently detected. Patient was a 64-year-old construction worker for whom we detected 2 erythematous psoriasiform reticular scaly plaques on peri-umbilical and medial knee. Biopsy established the diagnosis of Bowen's disease and polymerase chain reaction assay showed HPV-6, -18 co-infection. Patient was referred for surgical excision.

MÉTODOS: Estudo caso/controle, descritivo, transversal. Utilizou-se protocolo clínico para avaliação da morfologia genital de 2.916 recém-nascidos entre 19/04/2010 e 18/04/2011. O grupo controle foi formado pelos nascimentos sem anormalidades morfológicas ocorridos no dia e na maternidade em que o caso foi detectado. Teste exato de Fisher foi utilizado para análises de variáveis categóricas, e de Kruskal-Wallis, para igualdade de médias. RESULTADOS: Foram detectados 29 recém-nascidos com anormalidade genital (1:100. A maioria (93,2% foi examinada nos três primeiros dias de vida e apresentava apenas uma anormalidade. Os defeitos morfológicos compreenderam: ambiguidade genital evidente (1/29, fusão posterior de grandes lábios (1/29, micropênis (2/29, clitoromegalia (6/29, criptorquidia bilateral (6/29, hipospádia (9/29 e defeitos combinados (4/29 casos.

    Based on analytic techniques that collapse data into a single average value, it has been reported that women lack category specificity and show genital sexual arousal to a large range of sexual stimuli including those that both match and do not match their self-reported sexual interests. These findings may be a methodological artifact of the way in which data are analyzed. This study examined whether using an analytic technique that models data over time would yield different results. Across two studies, heterosexual (N = 19) and lesbian (N = 14) women viewed erotic films featuring heterosexual, lesbian, and gay male couples, respectively, as their physiological sexual arousal was assessed with vaginal photoplethysmography. Data analysis with traditional methods comparing average genital arousal between films failed to detect specificity of genital arousal for either group. When data were analyzed with smoothing regression splines and a within-subjects approach, both heterosexual and lesbian women demonstrated different patterns of genital sexual arousal to the different types of erotic films, suggesting that sophisticated statistical techniques may be necessary to more fully understand women's genital sexual arousal response. Heterosexual women showed category-specific genital sexual arousal. Lesbian women showed higher arousal to the heterosexual film than the other films. However, within subjects, lesbian women showed significantly different arousal responses suggesting that lesbian women's genital arousal discriminates between different categories of stimuli at the individual level. Implications for the future use of vaginal photoplethysmography as a diagnostic tool of sexual preferences in clinical and forensic settings are discussed. © 2015 Society for Psychophysiological Research.

    Introduction.  Female genital sexual pain (GSP) is a common, distressing complaint in women of all ages that is underrecognized and undertreated. Definitions and terminology for female GSP are currently being debated. While some authors have suggested that GSP is not per se a sexual dysfunction......, but rather a localized genial pain syndrome, others adhere to using clearly sexually related terms such as dyspareunia and vaginismus.

    Ground beetles of the subgenus Ohomopterus (genus Carabus) show marked divergence in species-specific male and female genital morphologies, which contributes to reproductive isolation among species. Characterizing the genetic basis of species-specific genital morphology is essential for understanding their diversification, but genomic information on Ohomopterus is not yet available. We analyzed mRNA extracted from abdominal sections of the last instar larvae and pupae of two sister species, Carabus (Ohomopterus) iwawakianus and C. (O.) uenoi, which show marked differences in genital morphology, to compare transcriptomic profiles using Roche 454 pyrosequencing. We obtained 1,608,572 high-quality reads and assembled them into 176,278 unique sequences, of which 66,049 sequences were combined into 12,662 clusters. Differential expression analyses for sexed pupae suggested that four and five clusters were differentially expressed between species for males and females, respectively. We also identified orthologous sequences of genes involved in genital development in Drosophila, which potentially affect genital development and species-specific genital morphology in Ohomopterus. This study provides the first large transcriptomic data set for a morphologically diversified beetle group, which can facilitate future studies on the genetic basis of species-specific genitalia.

    After an acute sexual assault, children and adolescents often present for medical evaluation and treatment. Physicians have an important role in both the medical and legal components of these cases. Careful physical examination and questioning are important in determining the origin of the trauma. In the presented case report, genital trauma after an acute sexual assault was noted and attributed to the alleged offender's penis piercing. The genital trauma caused by the piercing provided physical evidence linking offender to victim and may have implications for the victim's risk of HIV infection and other blood borne pathogens.

    In addition to epididymitis and testicular torsion, emergencies of the external genital are rare. Rapid diagnosis and therapy are essential so that immediate therapy can be provided, which is important for survival (Fournier gangrene) of the patient or for the preservation of erectile function (priapism and penile fracture). A detailed patient history and clinical examination are generally sufficient for correct diagnosis. Under certain circumstances, it might be useful to perform ultrasound, computed tomography scan or magnetic resonance imaging or retrograde urethrography. A urine analysis is obligatory. In case of penetrating injuries and genital trauma in females, additional imaging should be performed because these are often associated with concomitant injuries of the rectum, vagina, or bladder. Special cases are gunshot wounds, in which caliber and type of weapon play an important role for the degree of damage, and animal or human bites. For animal bites, the risk for rabies infection and in case of a human bite the risk for transmission of HIV and hepatitis should be taken into consideration and post-exposure prophylaxis should possibly be offered.

    Full Text Available Objectives: This study aimed to determine the prevalence of genital and sexually transmitted infections and its related factors in married women in Iran. Methods: We conducted a cross-sectional study of 4 274 married women living in urban and rural areas of the Zanjan province from 2012 to 2013. We used stratified cluster sampling to select the participants. Data collection included demographic characteristics, reproductive status, and cervical cytology results. Results: The prevalence of lower genital infections and sexually transmitted infections were 20.1% and 7.4%, respectively. The most common vaginal infection was bacterial vaginosis with a prevalence of 8.5%, and the most common sexually transmitted infection was Trichomonas vaginalis (1.4%. The use of the intrauterine device (IUD as a contraceptive, living in an urban area, and experiencing vaginal discharge were significantly related to genital tract and sexually transmitted infections. Conclusions: There was a high prevalence of genital infection among women living in Zanjab. Screening and treatment of genital infection are necessary to prevent adverse consequences in women who use an IUD or live in urban areas.

    This paper is a report of a study of women's awareness of the human papilloma virus and related health problems. Cervical cancer is an important cause of mortality, making up approximately 12% of all cancers in women. Awareness on the part of carriers of human papilloma virus is crucial in preventing transmission of the infection and protecting against cervical cancer. The study was performed as a cross-sectional descriptive study. The study consists of 79 human papilloma virus-positive women who had not been diagnosed with cervical cancer and 150 women who had not been diagnosed with human papilloma virus. Data were collected via questionnaires between November 2007 and April 2008. Percentages and chi-square test were used. A significantly higher percentage of women with positive human papilloma virus knew the definition of human papilloma virus, the fact that it is transmitted via sexual contact and that it can lead to cervical cancer than did women with negative human papilloma virus. It was established that approximately half the women with positive human papilloma virus presented at the hospital with a genital wart. None of the women knew that a Pap smear test was a necessary tool in the prevention of cervical cancer. Women with positive human papilloma virus have insufficient knowledge of human papilloma virus, sexually transmitted diseases, the health risks associated with human papilloma virus and the means of preventing these risks. It is therefore necessary to evaluate the education of health workers, and especially of nurses, on human papilloma virus and its prevention. © 2011 Blackwell Publishing Ltd.

    Full Text Available Today, "persistent" infections by certain types of human papillomavirus (HPV are considered necessary for developing cervical cancer. Producing efficient vaccines against these viruses may eventually lead to a great reduction in incidence and mortality rates of this cancer. In the case of HPV, the production of traditional vaccines usually based in dead or attenuated viruses is not possible due in part to the lack of systems where large quantities of viral particles could be obtained. Fortunately, the expression of the late L1 protein alone, or in combination with L2, leads to the generation of structures resembling true virions that have been called virus-like particles (VLPs and constitute excellent candidates as prophylactic vaccines. VLPs have shown to be very immunogenic, and have prevented development of natural or challenged infections in both animal systems and humans. Recently, HPV16 VLPs were shown to be very efficient to prevent the development of "persistent" infections, as determined by PCR assays, in a large group of vaccinated women. Therapeutic vaccines, on the other hand, are expected to have an impact on advanced lesions and residual illness, by taking advantaje of the fact that early E6 and E7 genes are thought to be constitutively expressed in cervical tumors and precursor lesions. Finally, DNA-based vaccines could represent a useful alternative for preventing infections by genital HPV.Actualmente, las infecciones "persistentes" por algunos tipos del virus del papiloma humano se consideran como necesarias para desarrollar cáncer cervicouterino. Por ello, el desarrollo de vacunas eficientes contra estos virus se ha considerado de suma importancia para poder eventualmente ayudar a controlar esta enfermedad, en países donde los programas de detección oportuna no han dado aún los resultados deseados. En el caso de estos virus no es posible el desarrollo de vacunas tradicionales, las cuales están basadas generalmente en el

    Background: The most common malignancy in women is breast carcinoma. The next common cancer is genital tract malignancies which constitute 14% of cancers in women. Objective of this study was to determine the type and frequency of genital tract malignancy in postmenopausal women and to find the age distribution of genital tract malignancies. Methods: This descriptive cross sectional study was conducted in Department of Obstetrics ad Gynaecology Unit-II at Liaquat University of Medical and Health Sciences, Jamshoro. All postmenopausal women, admitted in the unit due to various pathologies (abdominal masses, bleeding P/V etc.) from January 2005 to December 2007 were included in the study. Clinical evaluation and investigations were done on all patients. Those women who had benign diseases were excluded from the study. Malignancy was confirmed from histopathology report of biopsy specimen. These women were divided into 3 age groups: group I 70 years. Results: Out of 265 postmenopausal women admitted in ward during the study period, malignancy was confirmed in 68 cases (25.66%). The type of malignancy was cervical carcinoma (41, 60.28%), ovarian carcinoma (11, 16.17%), endometrial carcinoma (8, 11.76%), vulval carcinoma (5, 7.35%) vaginal carcinoma (2, 2.94%), and leiomyosarcoma of uterus (1, 1.47%). Increased frequency of cervical and endometrial carcinomas were seen in Group-I cases, while vulval carcinoma was seen more commonly in Group-II cases ( p =0.004). Conclusion: A very high frequency of cervical carcinoma was seen in our patients. There is need for more public awareness to integrate routine Gynae-Pap screening. (author)

    Full Text Available The margay (Leopardus wiedii belongs to Carnivora order and present’s nocturnal habits. There are few studies using this specie, whereas it is between feline species vulnerable to extinction. Thus, we propose a descriptive study about female genital system and behavior of the arteries responsible for the blood supply to these organs in margay. It used one exemplary victim of poaching that to death. The animal was stored in freezer. Subsequent to defrost at room temperature, it proceeded with the solution injection Leoprene Latex ‘650’ colored in red for better identification of vessels before the adjacent strutures. The specimen was fixed using an aqueous 10% formaldehyde with subsequent immersion in the same fixative solution. The genital system were dissected and the organs and arterial branches were identified and photodocumented. The female genital system of margay consists of a pair of ovaries, uterus with a pair of uterine horns, vagina and vulva. The arterial distribution of female system have a common vessel to iliac artery which branches and leads to internal pudendal artery sends a branch along the pudendal nerve pathway, urogenital artery. This, we performed divided into two branches, cranial and caudal. The cranial branch irrigates laterally cervix and uterine horns and caudal branch, vagina and vulva. The ovarian arteries, peers, originate from abdominal aorta only vascularization the ovaries. The female genital system and vascularization of the genitals organs of margay resembles of domestic carnivores including cats and some wild felines like the ocelot and find differences with the same description held in other domestic and wild species.

    The National Human Papillomavirus (HPV) Vaccination Program for females delivering the quadrivalent vaccine Gardasil has been included in the National Immunisation Program in Australia since 2007. Sentinel surveillance data show that genital wart incidence has been steadily declining since then. The objective of this study was to estimate the additional impact on genital warts as a result of male vaccination, which was approved by the Australian government in 2012 and commenced in 2013. We use a mathematical model of HPV transmission in the Australian heterosexual population to predict the impact of male vaccination on the incidence of genital warts. Our model produced results that are consistent with the actual observed decline in genital warts and predicted a much lower incidence, approaching elimination, in coming decades with the introduction of male vaccination. Results from our model indicate that the planned extension of the National HPV Vaccination Program to males will lead to the near elimination of genital warts in both the female and male heterosexual populations in Australia.

    Despite its importance in modulating HSV-2 pathogenesis, the nature of tissue-resident immune memory to HSV-2 is not completely understood. We used genital HSV-2 infection of guinea pigs to assess the type and location of HSV-specific memory cells at peripheral sites of HSV-2 infection. HSV-specific antibody-secreting cells were readily detected in the spleen, bone marrow, vagina/cervix, lumbosacral sensory ganglia, and spinal cord of previously-infected animals. Memory B cells were detected primarily in the spleen and to a lesser extent in bone marrow but not in the genital tract or neural tissues suggesting that the HSV-specific antibody-secreting cells present at peripheral sites of HSV-2 infection represented persisting populations of plasma cells. The antibody produced by these cells isolated from neural tissues of infected animals was functionally relevant and included antibodies specific for HSV-2 glycoproteins and HSV-2 neutralizing antibodies. A vigorous IFN-γ-secreting T cell response developed in the spleen as well as the sites of HSV-2 infection in the genital tract, lumbosacral ganglia and spinal cord following acute HSV-2 infection. Additionally, populations of HSV-specific tissue-resident memory T cells were maintained at these sites and were readily detected up to 150 days post HSV-2 infection. Unlike the persisting plasma cells, HSV-specific memory T cells were also detected in uterine tissue and cervicothoracic region of the spinal cord and at low levels in the cervicothoracic ganglia. Both HSV-specific CD4+ and CD8+ resident memory cell subsets were maintained long-term in the genital tract and sensory ganglia/spinal cord following HSV-2 infection. Together these data demonstrate the long-term maintenance of both humoral and cellular arms of the adaptive immune response at the sites of HSV-2 latency and virus shedding and highlight the utility of the guinea pig infection model to investigate tissue-resident memory in the setting of HSV-2 latency

    Full Text Available The prevalence of genital piercing among women is increasing. As the popularity increases, the number of complications from infection, injury, and retained jewelry is likely to rise. Techniques to remove embedded jewelry are not well described in the literature. The purpose of this report was to describe a case of a patient with a retained clitoral glans piercing, discuss a simple technique for outpatient removal, and review current evidence regarding associated risks of clitoral piercings. A 24-year-old female presented to the emergency department with an embedded clitoral glans piercing. Local anesthetic was injected into the periclitoral skin and a small superficial vertical incision was made to remove the ball of the retained barbell safely. In conclusion, among patients with retained genital piercing, outpatient removal of embedded jewelry is feasible. While the practice of female genital piercing is not regulated, piercing of the glans of the clitoris is associated with increased injury to the nerves and blood supply of the clitoris structures leading to future fibrosis and diminished function compared to piercing of the clitoral hood.

In conclusion, among patients with retained genital piercing, outpatient removal of embedded jewelry is feasible. While the practice of female genital piercing is not regulated, piercing of the glans of the clitoris is associated with increased injury to the nerves and blood supply of the clitoris structures leading to future fibrosis and diminished function compared to piercing of the clitoral hood.

    Ritual genital cutting for women, a common practice in Africa and elsewhere around the world, remains dangerous and controversial. In recent years, a 14-year-old girl living in Sierra Leone exsanguinated and died following a ritualistic genital cutting. Hoping to avoid that fate, women with backgrounds that accept ritual genital cutting may, when they reach majority age, ask plastic surgeons to perform genital alterations for cultural reasons. Although plastic surgeons routinely perform cosmetic procedures, unique ethical and legal concerns arise when an adult female patient asks a surgeon to spare her the tribal elder's knife and alter her genitalia according to tradition and custom. Misinformation and confusion about this issue exist. This article explores the ethical and legal issues relevant to this situation and explains how the thoughtful surgeon should proceed.

    A severe multi-systemic form of equid herpesvirus-1 infection is described in an adult zebra stallion. There was multifocal necrotizing rhinitis, marked hydrothorax and pulmonary oedema, with viral antigen expression in degenerating epithelial cells, local endothelial cells and intravascular leucocytes of the nasal mucosa and lung. Specific localization of EHV-1 infection was seen in the testes and epididymides, including infection of Leydig cells and germinal epithelium, which would have facilitated venereal shedding of virus in life. The case provided a unique opportunity to study hitherto undescribed aspects of the pathogenesis of naturally occurring EHV-1 infection in the male equine genital tract. Restriction digests of the isolate demonstrated a pattern similar to that of EHV-1 isolates previously recovered from aborted zebra and onager fetuses.

    Neonatal herpes simplex virus infections are rare, but are associated with significant morbidity and mortality. Most newborns acquire herpes simplex virus infection in the peripartum period. For peripartum transmission to occur, women must be shedding the virus in their genital tracts symptomatically or asymptomatically around the time of delivery. There are evidence-based interventions in pregnancy to prevent the transmission to the newborn. Caesarean section should be performed in the presence of herpetic lesions, and antiviral prophylaxis in the last weeks of pregnancy is recommended to suppress genital tract herpes simplex virus at the time of delivery. The diagnosis and early treatment of neonatal herpes simplex virus infections require a high index of suspicion, especially in the absence of skin lesions. It is recommended to rule out herpes simplex virus infections in those newborns with mucocutaneous lesions, central nervous system involvement, or septic appearance. The prognosis of newborns with skin, eye, and/or mouth disease in the high-dose acyclovir era is very good. Antiviral treatment not only improves mortality rates in disseminated and central nervous system disease, but also improves the rates of long-term neurodevelopmental impairment in the cases of disseminated disease. Interestingly, a 6-month suppressive course of oral acyclovir following the acute infection has improved the neurodevelopmental prognosis in patients with CNS involvement.

    Genital melanomas (GM) are the second most common cancer of the female external genitalia and may be confused with atypical genital nevi (AGN), which exhibit atypical histological features but have benign behavior. In this study, we compared the clinical, histological, and molecular features of 19 GM and 25 AGN. We described chromosomal copy number aberrations and the mutational status of 50 oncogenes and tumor suppressor genes in both groups. Our study showed that a pigmented lesion occurring in mucosal tissue, particularly in postmenopausal women, was more likely to be a melanoma than a nevus. GM had high levels of chromosomal instability, with many copy number aberrations. Furthermore, we found a completely nonoverlapping pattern of oncogenic mutations when comparing GM and AGN. In GM, we report somatic mutations in KIT and TP53. Conversely, AGN had frequent BRAF V600E mutations, which were not seen in any of the GM. Our results show that GM and AGN have distinct clinical and molecular changes and that GM have a different mutational pattern compared with AGN. Copyright © 2016 The Authors.

    Full Text Available Regulation of immune responses is critical for controlling inflammation and disruption of this process can lead to tissue damage. We reported that CXCL13 was induced in fallopian tube tissue following C. trachomatis infection. Here, we examined the influence of the CXCL13-CXCR5 axis in chlamydial genital infection.Disruption of the CXCL13-CXCR5 axis by injecting anti-CXCL13 Ab to BALB/c mice or using Cxcr5-/- mice increased chronic inflammation in the upper genital tract (UGT; uterine horns and oviducts after Chlamydia muridarum genital infection (GT. Further studies in Cxcr5-/- mice showed an elevation in bacterial burden in the GT and increased numbers of neutrophils, activated DCs and activated NKT cells early after infection. After resolution, we noted increased fibrosis and the accumulation of a variety of T cells subsets (CD4-IFNγ, CD4-IL-17, CD4-IL-10 & CD8-TNFα in the oviducts. NKT cell depletion in vitro reduced IL-17α and various cytokines and chemokines, suggesting that activated NKT cells modulate neutrophils and DCs through cytokine/chemokine secretion. Further, chlamydial glycolipids directly activated two distinct types of NKT cell hybridomas in a cell-free CD1d presentation assay and genital infection of Cd1d-/- mice showed reduced oviduct inflammation compared to WT mice. CXCR5 involvement in pathology was also noted using single-nucleotide polymorphism analysis in C. trachomatis infected women attending a sub-fertility clinic. Women who developed tubal pathology after a C. trachomatis infection had a decrease in the frequency of CXCR5 SNP +10950 T>C (rs3922.These experiments indicate that disruption of the CXCL13-CXCR5 axis permits increased activation of NKT cells by type I and type II glycolipids of Chlamydia muridarum and results in UGT pathology potentially through increased numbers of neutrophils and T cell subsets associated with UGT pathology. In addition, CXCR5 appears to contribute to inter-individual differences in

    Full Text Available Human papilloma virus (HPV, known to be an etiological agent for genital cancers, has been suggested also to be a possible contributory agent for lung cancer. Alternatively, lung cancer, formerly considered to be solely a smoker's disease, may now be more appropriately categorised into never smoker's and smoker's lung cancer. Through this paper we attempt to bring forth the current knowledge regarding mechanisms of HPV gaining access into the lung tissue, various strategies involved in HPV-associated tumorigenesis in lung tissue.

  17. In defence of genital autonomy for children.

    Arora and Jacobs (2016) assume that liberal societies should tolerate non-therapeutic infant male circumcision, and argue that it follows from this that they should similarly tolerate-or even encourage-what the authors regard as 'de minimis' forms of female genital mutilation (as defined by the World Health Organization). In this commentary, I argue that many serious problems would be likely to follow from a policy of increased tolerance for female genital mutilation, and that it may therefore be time to consider a less tolerant attitude toward non-therapeutic infant male circumcision. Ultimately, I suggest that children of whatever sex or gender should be free from having healthy parts of their most intimate sexual organs either damaged or removed, before they can understand what is at stake in such an intervention and agree to it themselves.

    Full Text Available Objective: To detect some common microbial agents of female genital discharges in order to improve the current syndromic management of abnormal vaginal discharge. Methods: A prospective study of female genital swabs collected from Primary Health Care Centres, Jos, and analysed for microscopy, culture and sensitivity in Jos University Teaching Hospital, December 2006 to December 2007 was carried out. Results: Microbial agents were detected in 70% (700 of a total 1 000 female genital swabs studied. Candida species peaked with 42.0% (420 out of the 1000 samples, followed by Gardnerella vaginalis, an agent of bacterial vaginosis with 26.0%. The distribution of abnormal vaginal discharge was highest in young adults aged 21 to 30 years. Conclusions: It is concluded that abnormal vaginal discharge is most prevalent in the young sexually active age group with Candida species as the commonest agent. We recommend prevention, early diagnosis and prompt treatment of infective female genital discharge in order to reduce the menace of HIV transmission.

    Full Text Available Objective. To compare genital HSV shedding among HIV-positive and HIV-negative women. Methods. Women with and without known HIV infection who delivered at the University of Washington Medical Center between 1989–1996 had HSV serologies done as part of clinical care. Genital swabs from HSV-2-seropositive women were evaluated by real-time quantitative HSV DNA PCR. Results. HSV-2 seroprevalence was 71% and 30% among 75 HIV-positive and 3051 HIV-negative women, respectively, (P<.001. HSV was detected at delivery in the genital tract of 30.8% of HIV-seropositive versus 9.5% of HIV-negative women (RR=3.2, 95% CI 1.6 to 6.5, P=.001. The number of virion copies shed per mL was similar (log 3.54 for HIV positive versus 3.90 for HIV negative, P=.99. Conclusions. Our study demonstrated that HIV-, HSV-2-coinfected women are more likely to shed HSV at delivery.
