    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.

    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. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

  18. Medroxyprogesterone acetate and levonorgestrel increase genital mucosal permeability and enhance susceptibility to genital herpes simplex virus type 2 infection.

    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.

    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

    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.

    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.

    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.

    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.

    Full Text Available Las enfermedades bullosas o ampollares comprenden un grupo heterogéneo de cuadros cuya lesión elemental común es la ampolla. Los pénfigos y los penfigoides pertenecen al grupo de las enfermedades bullosas de origen autoinmunitario. El prolapso genital es el descenso o desplazamiento de los órganos pélvicos, a través de la vagina y en dirección a la vulva, que se produce como consecuencia del fallo de sus elementos de suspensión y sustentación así como la inervación y musculatura del sistema urinario e intestinal. En este caso presentamos nuestra experiencia en el manejo y tratamiento tópico de lesiones por pénfigo ampolloso en prolapso visceropélvico total que dificultaban la cirugía.

    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.

    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.

    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.

    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.

    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.

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

    Science.gov (United States)

    2014-01-01

    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.

    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.

    1987-06-04

    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.

    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.

    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

    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.

  1. The role of the local microenvironment in regulating susceptibility and immune responses to sexually transmitted viruses in the female genital tract.

    2009-12-01

    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.

    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.

    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.

    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

    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.

    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.

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. Evaluation of local symptoms has established that burning have caused minimal discomfort for patients of groups 3 and 4 and itch and soreness--of groups 1 and 3. The least pronounced exacerbations were noted in patients of group 3. Intramuscular administration of fortepren

    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

    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 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.

    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.

    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 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.

    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

    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.

    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.

    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.

    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(®).

    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.

    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.

  4. 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.

    Relatively little is known about the human T-cell response to herpes simplex virus type 2 (HSV-2) in the female genital tract, a major site of heterosexual HSV-2 acquisition, transmission, and reactivation. 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.

    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.

    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.

    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).

    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). Only baseline HIV-1 plasma viral load was independently associated with genital HIV-1 RNA shedding (aOR, 7.6; 95% CI, 3.3-17.2, P genital sampling, and inclusion of genital sites other than the cervix.

    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.

  11. 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.

    2010-06-01

    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.

    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.

    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.

    Lee, Amanda J; Ashkar, Ali A

    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.

    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.

    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.

    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.

    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

    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.

    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

    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.

    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

    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

    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) 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

    Background: Infection with human papilloma virus (HPV) is the main cause of cervical cancer, but the local risk factors have not been sufficiently assessed. Aim: The study is aimed at determining the prevalence and to evaluate the local risk factors of HPV infection in cervical smears at the Imo State University Teaching Hospital, Orlu, Nigeria. Subjects and Methods: The participants involved 445 randomly selected sexually active women attending the antenatal, postnatal, gynecology and family planning clinics in the Department of Obstetrics and Gynecology of the university between April 2004 and May 2012. A questionnaire assessing various socio-demographic characteristics of the participants was administered. The pap smears of the participants were examined microscopically for evidence of HPV infection. The SPSS version 17.0 (Chicago, Illinois, USA) was used to compute and analyze the results. The results were presented in tables as simple percentages. Tests of significance using the Chi-square and fisher exact tests were applied where appropriate. Results: The prevalence rate of HPV was 10.3%. The peak age-specific prevalence of 11.7% occurred in the 15-19 years age group. There were significant associations between the occurrence of HPV and multiple sexual partners, coital frequency, multiparity, contraceptive use, marital status, low socio-economic status, abnormal vaginal discharge, irregular menstruation, post-coital and post-menopausal bleeding, (P < 0.05). Conclusion: All sexually active women including teenagers should be screened for cervical HPV infection in an organized systematic program equipped with a good call and recall system. There is, therefore, a need to move emphasis from the current practice of opportunistic screening to a systematic screening of the whole population at risk despite cost implications. PMID:24380003

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.

    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

    Full Text Available OBJECTIVE: To characterize the prevalence and distribution of genital human papillomavirus (HPV types among women in Jamaica, and to explore risk factors associated with HPV infection. METHODS: This was a cross-sectional study that took place in April-July 2010 with 852 sexually-active women, 16-49 years of age, who had attended a selected public or private primary health clinic in one of Jamaica's four health authority regions. Sociodemographic data was collected from each participant by trained study staff. Each participant had a gynecological examination that included a clinical Pap test and a cervical sample for HPV detection and typing-performed using the Research Use Only Linear Array (LA genotyping assay (Roche Diagnostics Corp., Indianapolis, Indiana, United States. Overall and type-specific prevalence of HPV infection was calculated for 37 HPV types included in the LA genotyping assay. RESULTS: HPV DNA was detected in 460 of the 852 women (54.0%. Oncogenic HPV was detected in 297 women (34.9% and HPV types 16/18 were found in 86 women (10.1%. The most frequently occurring HPV types were: 16 (6.2%; 35 (6.0%; 62 and 83 (5.5%; 61 and 58 (5.4%; 84 (4.7%; 18 (4.3%; and, 66 and 81 (4.2%. HPV prevalence was highest among women who were single, young (16-19 years, and had had more than three sexual partners in their lifetime. CONCLUSIONS: These results, coupled with high rates of cervical cancer, support introducing HPV vaccines while maintaining and strengthening cervical cancer screening services. Policy decisionmaking that reflects these results is instrumental to establishing a comprehensive cervical cancer program in Jamaica.OBJETIVO: Determinar la prevalencia y la distribución de los tipos de virus de los papilomas humanos (VPH genitales en las mujeres de Jamaica y explorar los factores de riesgo asociados con la infección por VPH.

    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

    Local mucosal cellular immunity is critical in providing protection from HSV-2. To characterize and quantify HSV-2-reactive mucosal T cells, lymphocytes were isolated from endocervical cytobrush and biopsy specimens from 17 HSV-2-infected women and examined ex vivo for the expression of markers associated with maturation and tissue residency and for functional T-cell responses to HSV-2. Compared with their circulating counterparts, cervix-derived CD4+ and CD8+ T cells were predominantly effector memory T cells (CCR7-/CD45RA-) and the majority expressed CD69, a marker of tissue residency. Co-expression of CD103, another marker of tissue residency, was highest on cervix-derived CD8+ T cells. Functional HSV-2 reactive CD4+ and CD8+ T-cell responses were detected in cervical samples and a median of 17% co-expressed CD103. HSV-2-reactive CD4+ T cells co-expressed IL-2 and were significantly enriched in the cervix compared with blood. This first direct ex vivo documentation of local enrichment of HSV-2-reactive T cells in the human female genital mucosa is consistent with the presence of antigen-specific tissue-resident memory T cells. Ex vivo analysis of these T cells may uncover tissue-specific mechanisms of local control of HSV-2 to assist the development of vaccine strategies that target protective T cells to sites of HSV-2 infection.

    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.

    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.

    Laboratory diagnosis of molluscum contagiosum virus (MCV) is important as lesions can be confused with those caused by Cryptococcus neoformans, herpes simplex virus, human papillomavirus, and varicella-zoster virus. To develop a rapid method for identifying patients infected with MCV via swab sampling. Two dual-labeled probe real-time PCR assays, one homologous to the p43K gene and one to the MC080R gene, were designed. The p43K PCR was designed to be used in conjunction with Pyrosequencing for confirmation of PCR products and discrimination between MCV1 and MCV2. Both PCR assays were optimized with respect to reaction components, thermocycling parameters, and primer and probe concentrations. The specificities of both PCR assays were confirmed by non-amplification of 38 known human pathogens. Sensitivity assays demonstrated detection of as few as 10 copies per reaction. Testing 703 swabs, concordance between the two real-time PCR assays was 99.9%. Under the developed conditions, Pyrosequencing of the p43K PCR product was capable of providing enough nucleotide sequence to definitively differentiate MCV1 and MCV2. These real-time PCR assays can be used for the rapid, sensitive, and specific detection of MCV and, when combined with Pyrosequencing, can further discriminate between MCV1 and MCV2.

    Full Text Available El desarrollo de tecnologías moleculares aplicadas a estudios ambientales ha permitido constatar que incluso en países altamente industrializados existe una alta prevalencia de virus en el medio ambiente, lo que causa un importante impacto en la salud pública e importantes pérdidas económicas, principalmente a través de la transmisión de virus por agua y alimentos. Concentraciones significativas de virus son detectadas en las aguas vertidas al ambiente y en los biosólidos generados en plantas de tratamiento de agua residual. En este trabajo se describen las características generales de la contaminaci ón ambiental por virus, principalmente por virus emergentes, analizándose con mayor profundidad los virus de la hepatitis E (VHE y los poliomavirus humanos como los virus contaminantes ambientales de más reciente identificación en países industrializados. 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.

    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.

    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.

    2014-02-01

    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.

    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.

    Full Text Available El 9 de diciembre de 2013 la Organización Panamericana de la Salud emitió una alerta epidemiológica debido a la detección de los primeros casos autóctonos de fiebre del Chikun-gunya en el continente americano; desde entonces este se ha convertido en un problema de salud pública. El primer reporte de un brote por el virus del Chikungunya se presentó en 1952-1953 en Tanzania. Las experiencias en epidemias en otros países han centrado la atención en que la presentación clínica no siempre tiene un comportamiento similar. Hasta 2005 todos los reportes mencionaban la presentación de la enfermedad como benigna y con cuadros clínicos bastantes similares, sin embargo, la aparición de epidemias después de ese año en las Islas Reunión y en la India describieron la presencia de cuadros graves, atípicos y un aumento de la mortalidad relacionados con la enfermedad. La región de las Américas debe prepararse para esta nueva epidemia. Esto hace necesario mejorar los conocimientos sobre la enfermedad; y un primer abordaje es a través de una descripción de la historia y epidemiología de la enfermedad por el virus del Chikungunya en el mundo.

    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

    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.

  18. Herpes simplex virus: 'to disclose or not to disclose.' An exploration of the multi-disciplinary team's role in advising patients about disclosure when diagnosed with genital herpes simplex virus.

    2017-07-01

    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.

    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.

    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.

Solo apelando a los conocimientos actuales de la Psicoendocrinoneuroinmunologia, que describe la vinculación basada en la teoría de la complejidad de este suprasistema, que comparte receptores y mediadores químicos, se puede disipar el asombro y llegar a comprender la esencia científica de este problema de salud. El VIH es un virus que posee un elevado trofismo por el Sistema Nervioso Central (SNC, infesta a los macrófagos, a las células multinucleadas, derivadas de ellos, y a las neuroglias; no se tiene claro si invade las neuronas, pero los productos tóxicos, derivados de su penetración al SNC y los mecanismos inflamatorios desencadenados, provocan la muerte de las mismas. La glicoproteína GP120, encontrada en la envoltura viral, ha sido la principal responsable de la activación de las citoquinas, sustancias encargadas de desencadenar las cascadas inflamatorias que destruyen la mielina, generando el complejo demencial asociado al VIH-SIDA, descrito en la década del 80. La deficiencia en la neurotransmisión serotoninérgica y el aumento de la activación del receptor de glutamato N-metil-d-aspartato NMDA, propician la depresión y su mantención en el tiempo, posee efectos neurotóxicos y neurodegenerativos demenciantes.

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.

    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.

    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.

    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

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.

    Herpes simplex infections (HSV1/2) are characterized by recurrent symptoms, a risk of neonatal herpes, and the facilitation of HIV transmission. In Germany, HSV1/2 infections are not notifiable and data are scarce. A previous study found higher HSV1/2 seroprevalences in women in East Germany than in women in West Germany. We assessed changes in the HSV1/2 seroprevalences over time and investigated determinants associated with HSV1/2 seropositivity to guide prevention and control. The study was based on the German Health Interview and Examination Survey for Adults (DEGS; 2008-2011) and the German National Health Interview and Examination Survey (GNHIES; 1997-1999). We tested serum samples from DEGS participants for HSV1 and HSV2 immunoglobulin G. We used Pearson's χ 2 test to compare the HSV1/HSV2 seroprevalences in terms of sex, age, and region of residence (East/West Germany) and investigated potential determinants by calculating prevalence ratios (PR) with log-binomial regression. All statistical analyses included survey weights. In total, 6627 DEGS participants were tested for HSV1, and 5013 were also tested for HSV2. Overall, HSV1 seroprevalence decreased significantly from 1997-1999 (82.1%; 95%CI 80.6-83.6) to 2008-2011 (78.4%; 95%CI 77.8-79.7). In the same period, overall HSV2 seroprevalence decreased significantly from 13.3% (95%CI 11.9-14.9) to 9.6% (95%CI 8.6-10.8), notably in 18-24-year-old men (10.4 to 0%) in East Germany. Women were more likely than men to be seropositive for HSV1 (PR 1.1) or HSV2 (PR 1.6). A lower level of education, smoking, and not speaking German were associated with HSV1 in both sexes. Women of older age, who smoked, or had a history of abortion and men of older age or who had not attended a nursery school during childhood were more often seropositive for HSV2. The reduced seroprevalences of HSV1 and HSV2 leave more people susceptible to genital HSV1/2 infections. Practitioners should be aware of HSV infection as a differential

    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.

    Human papillomavirus (HPV) causes external genital lesions (EGLs) in men, including condyloma and penile intraepithelial neoplasia (PeIN). We sought to determine the incidence of pathologically confirmed EGLs, by lesion type, among men in different age groups and to evaluate the HPV types that were associated with EGL development. HPV Infection in Men (HIM) study participants who contributed ≥2 visits from 2009-2013 were included in the biopsy cohort. Genotyping by an HPV line-probe assay was performed on all pathologically confirmed EGLs. Age-specific analyses were conducted for incident EGLs, with Kaplan-Meier estimation of cumulative incidence. This biopsy cohort included 2754 men (median follow-up duration, 12.4 months [interquartile range, 6.9-19.2 months]). EGLs (n = 377) were pathologically confirmed in 228 men, 198 of whom had incident EGLs. The cumulative incidence of any EGL was highest among men <45 years old and, for condyloma, decreased significantly over time with age. The genotype-specific incidence of EGL varied by pathological diagnoses, with high- and low-risk genotypes found in 15.6% and 73.2% of EGLs, respectively. Condyloma primarily contained HPV 6 or 11. While PeIN lesions primarily contained HPV 16, 1 PeIN III lesion was positive for HPV 6 only. Low- and high-risk HPV genotypes contribute to the EGL burden. Men remain susceptible to HPV-related EGLs throughout the life span, making it necessary to ensure the longevity of immune protection against the most common causative HPV genotypes. © The Author 2014.

    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.

    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.

    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.

    Quantitative estimation of the extent to which the immune system's protective effect against one herpes simplex virus type 2 (HSV-2) infection protects against infection with additional HSV-2 strains is important for understanding the potential for HSV-2 vaccine development. Using viral genotyping, we estimated the prevalence of HSV-2 dual-strain infection and identified risk factors. People with and without HIV infection participating in HSV-2 natural history studies (University of Washington Virology Research Clinic) and HIV prevention trials (HIV Prevention Trials Network 039 and Partners in Prevention HSV/HIV Transmission Study) in the US, Africa, and Peru with 2 genital specimens each containing ≥105 copies herpes simplex virus DNA/ml collected a median of 5 months apart (IQR: 2-11 months) were included. It is unlikely that 2 strains would be detected in the same sample simultaneously; therefore, 2 samples were required to detect dual-strain infection. We identified 85 HSV-2 SNPs that, in aggregate, could determine whether paired HSV-2 strains were the same or different with >90% probability. These SNPs were then used to create a customized high-throughput array-based genotyping assay. Participants were considered to be infected with more than 1 strain of HSV-2 if their samples differed by ≥5 SNPs between the paired samples, and dual-strain infection was confirmed using high-throughput sequencing (HTS). We genotyped pairs of genital specimens from 459 people; 213 (46%) were men, the median age was 34 years (IQR: 27-44), and 130 (28%) were HIV seropositive. Overall, 272 (59%) people were from the US, 59 (13%) were from Peru, and 128 (28%) were from 8 countries in Africa. Of the 459 people, 18 (3.9%) met the criteria for dual-strain infection. HTS and phylogenetic analysis of paired specimens confirmed shedding of 2 distinct HSV-2 strains collected at different times in 17 pairs, giving an estimated dual-strain infection prevalence of 3.7% (95% CI = 2

    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.

    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.

    To relate the Female Genital Mutilation as a negative factor for the achievement of the Millennium Development Goals 1, 3, 4, 5 and 6. Data collection was through review literature review between in the years 2014 and 2015 in the databases Medline/PubMed, Web of Science, LILACS, SCIELO, Tesis Doctorales TESEO and in the webs of WOK, UNICEF, UNAF and WHO using the descriptors: female circumcision, millennium development goals, rights of women. Articles published between years 2010 y 2015, were included and finally 24 articles were selected. The Female Genital Mutilation is based on gender discrimination, and reinforces and encourages the circle of poverty. This practice causes physical complications that may affect the infant mortality and morbidity, complications in pregnancy and childbirth and there is a relationship between the practice and the transmission of human immunodeficiency virus. The fight against Female Genital Mutilation contributes to the achievement of five of the eight Millennium Goals.

    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.

    Griffins O Manguro

    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.

    Full Text Available Understanding the correlates of HIV shedding is important to inform strategies to reduce HIV infectiousness. 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.

    Full Text Available

    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. Adicionalmente a esto, dentro de la población neuronal, parece existir una subpoblación con mayor susceptibilidad hacia la infección por el virus. Para comprobar esta hipótesis, se caracterizaron las subpoblaciones neuronales presentes en estos cultivos utilizando un criterio morfológico (diámetro neuronal y uno bioquímico (presencia de neuropéptidos como marcadores de subpoblaciones en el ganglio.

  2. Chemokine-mediated immune responses in the female genital tract mucosa.

    Deruaz, Maud; Luster, Andrew D

    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.

    Few case reports have documented the use of topical cidofovir for refractory genital herpes simplex virus (HSV) ulcers in human immunodeficiency virus (HIV) infected patients. This drug formulation lacks a standardized concentration or even a procedural outline as to how it should be compounded. We aim to discuss the utilization of topical cidofovir in addition to presenting a procedural means of compounding it for treatment of refractory genital HSV ulcers. Our patient completed 21 days of intravenous foscarnet and 13 days of topical cidofovir with clinical improvement in the penile and scrotal ulcers. Genital herpes is a concern in patients with HIV because it generally manifests as a persistent infection. Physicians should be aware that when patients fail to respond to the conventional treatment regimens for genital HSV in a timely manner, other options are available, such as topical cidofovir as an adjuvant to systemic antivirals.

    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.

    Full Text Available Desde que en abril de 2009 la Organización Mundial de la Salud (OMS alertó de la existencia de casos de infección humana por un nuevo virus de la gripe AH1N1 de origen porcino, las autoridades sanitarias de Andalucía activaron un plan específico de actuación para dar respuesta a la crisis sanitaria. Las actividades de vigilancia desarrolladas permitieron disponer de información oportuna sobre las características clínicas, epidemiológicas y virológicas de la enfermedad. En los primeros días se pusieron en marcha planes de contingencia basados en la vigilancia epidemiológica y medidas de control de brotes mediante sistemas de alerta y respuesta rápida. Tras la declaración de fase 6 de alerta pandémica la vigilancia centinela de gripe y de casos graves fueron de utilidad para la planificación de servicios sanitarios, para reducir la transmisión e identificar y para proteger a los grupos de población más vulnerables. El comportamiento de la gripe pandémica en Andalucía ha sido similar al observado en el resto del mundo. La tasa de ataque fue parecida a la de una temporada de gripe estacional y el pico de máxima incidencia se alcanzó en la semana 46/2009. La mayoría de los casos fueron leves y afectó sobre todo a población joven. En los casos hospitalizados la media de edad fue de 32 años. Las patologías previas de base y factores de riesgo mas frecuentes presentes en los casos graves fueron enfermedades pulmonares, tabaquismo y obesidad mórbida (IMC>40. Un escenario de impacto de la onda pandémica en Andalucía, con una tasa de ataque esperada de entre el 2 y 5%, se preparó teniendo en cuenta lo observado durante la onda epidémica en los países del hemisferio sur. Las características de la epidemia en cuanto a su magnitud, gravedad y letalidad, se ajustaron a este escenario utilizado.

  14. Male genital trauma

    International Nuclear Information System (INIS)

    Jordan, G.H.; Gilbert, D.A.

    1988-01-01

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references

  15. Female genital mutilation in Britain.

    Science.gov (United States)

    Black, J A; Debelle, G D

    1995-06-17

    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.

    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.

    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.

    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.

  4. Guidance on management of asymptomatic neonates born to women with active genital herpes lesions.

    Kimberlin, David W; Baley, Jill

    2013-02-01

    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.

    2003-01-01

    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 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.

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

    Science.gov (United States)

    Langley, C

    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.

  10. [Factual approach to the treatment of genital herpes].

    2000-05-01

    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.

    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

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.

    necessariamente ausência de vírus da hepatite C no fígado. A associação de autoimunidade à hepatite C é questionável. Os marcadores imunes são freqüentemente detectados em baixos níveis. A modulação da resposta imune ao envelope protéico E2, após injeção de plasmídios DNA, tem sido usada para induzir respostas imunes específicas ao vírus da hepatite C. O espectro de tais respostas poderia ser ampliada mediante combinação de plasmídios, vias de administração e outras formas de imunógenos codificados (vacinas a base de peptídios. Tais estratégias podem vir a ser importantes, em breve, no combate aos altamente mutantes vírus da hepatite C. O papel patogênico dos novos vírus G e TT das hepatites está em estudos, porém é de consenso que suas associações com doença hepática ativa é fortuita.Hepatitis C virus was identified in 1989 as the main causative agent of non-A, non-B and was followed by the recognition of a high prevalence of hepatitis C virus infection after transfusion of infected blood or blood products and in association with intravenous drug abuse. The availability of sensitive and reliable techniques to screen blood for hepatitis C virus has reduced the incidence of post-transfusion hepatitis. True healthy carriers of hepatitis C virus did not exist. Aproximately 95% of hepatitis C virus infected individuals can be identified by third generation anti- hepatitis C virus testing. Retrospective studies of iatrogenic hepatitis C virus infection are the main source of the natural history of the disease. The distribution of different hepatitis C virus genotypes varies according to the grographic region. In South America, Europe, The United States and Japan hepatitis C virus genotypes 1, 2 and 3 account for the majority of the infections, being (subtype 1b the most prevalent. Epidemiological parameters (age, risk factors and duration of infection may be associated with hepatitis C virus genotypes (intravenous drug abuse with types 1-a and 3

    Ciertos tipos de VPH son los agentes etiológicos de cáncer cervical, lesiones tempranas y ulceras genitales (1-4. Las infecciones por VPH tienen alta prevalencia y se transmiten por contacto sexual (5-6. Los datos publicados sobre incidencia son en mujeres jóvenes pero son escasos los datos en mujeres de mediana edad (7-10. Se sugiere que los VPH de alto riesgo tienen mayor duración que los de bajo riesgo (7-11.

    Para examinar estos aspectos se presentan los datos sobre una cohorte de 2,200 mujeres seguidas desde Noviembre de 1993 a julio del 2001 en Bogotá, sexualmente activas, entre 13-85 años de edad. Se realizó detección y tipificación del VPH mediante PCR estándar GP5+/GP6+ e inmunoensayo enzimático (EIA. Para el cálculo de la incidencia se usaron métodos de persona-tiempo, asumiendo que la infección se presentó en la mitad de periodo entre la última visita negativa a VPH y la siguiente positiva.

    Para este análisis se tomaron 1,610 mujeres después de excluir las infecciones prevalentes. La duración media de seguimiento por paciente fue de 4,1 años (Rango intercuartil RIQ 3.2-5.0, la mediana de seguimiento fue de 7 meses (RIQ 6.0-12.0, más del 65% de las mujeres tenían 4 visitas y la edad media fue de 32,3 años (RIQ 26,5-39,2. La incidencia para infección por VPH fue de 6,2 por 100 personas-año, siendo la incidencia mayor para los tipos de alto riesgo que para los de bajo riesgo.

    Los tipos de mayor incidencia fueron los VPH 16, 58, 31 y 18. La curva de incidencia por edad mostró una forma bimodal, con un pico de incidencia de 15-19 años, que decrece hasta alrededor de los 50 años, cuando presenta un pequeño incremento

    Full Text Available La infección por el virus de la inmunodeficiencia humana (VIH en los niños se comporta en forma diferente a la infección en adultos, no sólo por sus manifestaciones clínicas sino por la forma de hacer el diagnóstico y el tratamiento. Los niños tienen un sistema inmune en desarrollo y no poseen inmunidad previa para la mayoría de los agentes infecciosos, a diferencia de los pacientes adultos, cuyo sistema inmune ya es competente. Por lo tanto, las infecciones oportunistas de los adultos generalmente corresponden a reactivaciones, mientras que las de los niños usualmente son el resultado de infecciones primarias. El examen físico del neonato infectado por el VIH-1 puede ser normal pero, a medida que avanza la infección, van apareciendo manifestaciones clínicas que sugieren un compromiso inmunológico. Los hallazgos más frecuentes en los niños, a diferencia de los adultos, son: infecciones bacterianas recurrentes, edema parotídeo crónico, neumonía intersticial linfoide y deterioro neurológico prematuro. Ciertos sistemas, como el respiratorio y el nervioso central, son atacados con frecuencia y gravedad y enfermedades como la tuberculosis revisten características especiales en los niños infectados por el VIH-1. Presentation of HIV infection in children differs from than in adults: there are different clinical manifestations and, therefore, diagnosis and treatment have their own particularities. Unlike adults, children have a developing immune system without previous immunity for many infectious agents; consequently, opportunistic infections in children correspond to primary infections while those in adults usually result from reactivations. Physical examination in HIV-infected newborns is usually normal, but as the infection progresses clinical manifestations of immunological incompetence appear. In contrast to adults, the most frequent findings in children are recurrent bacterial infections, parotid chronic edema, lymphoid

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.

In this report, after cell infection with BTV, the activation of caspase 8 was detected, proving the extrinsic receptor binding apoptotic pathway. Apoptosis followed a sequential pathway involving the detection of activated Bcl-2 family members. Furthermore, its translocation to the mitochondria, as well as the release of cytochrome c and

    Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxaemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnoea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome. (author)

    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.

  9. 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

    Full Text Available El virus de Epstein-Barr (VEB es un agente patógeno común para los humanos y su efecto en la infección vertical es poco estudiado. Durante el embarazo hay riesgo a contraer infecciones que afectan al feto. La infección adquirida antes del nacimiento ocasiona abortos, mortinatos, malformaciones, retraso en el crecimiento intrauterino, prematuridad y secuelas por infección postnatal crónica. Los efectos inmediatos o a largo plazo representan un problema a nivel mundial. Durante el embarazo se ha mostrado una prevalencia del 98% y aproximadamente el 40% de las embarazadas son susceptibles y transmitirán el virus al feto. Los actuales exámenes clínicos de rutina revelan pocos hallazgos específicos en la madre pues en su mayoría la infección por VEB tiene un curso asintomático. La poca efectividad en su tratamiento hace que la prevención y el diagnóstico sean de gran importancia. Se conoce que el VEB se mantiene latente en el 90% de los pacientes después de la infección primaria y que la infección puede ser reactivada debido a diversos factores como el estrés crónico, posiblemente debido a la disminución de la respuesta inmune celular. En la presente investigación se evaluó la prevalencia de la infección por VEB en mujeres gestantes y con aborto que se encontraban durante las primeras 15 semanas de embarazo. Las muestras de pacientes de la consulta de obstetricia en diferentes ambulatorios de los Municipios Libertador y Campo Elías del Estado Mérida y de mujeres en la sala de emergencia obstétrica del Instituto Autónomo Hospital Universitario de Los Andes (IAHULA que acudieron por aborto durante las primeras semanas, se analizaron con una prueba ELISA para la detecctar anticuerpos séricos de tipo IgG VCA-VEB que no discriminan entre una primoinfección y una infección pasada. El 35% de la población de estudio fueron 9 mujeres en gestación sin antecedente de aborto y el 65% corresponde a 17 mujeres que historia previa

    2008-06-01

    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. Por esta vía se concluye con la idea paradójica de que la genitalidad es la expresión de una pulsión parcial (en oposición a una aparente totalidad cuya fuente es el pene.

    Full Text Available OBJETIVO: Determinar la seroprevalencia de infección por el virus herpes simplex tipo 2 y los factores epidemiológicos asociados a ella, en tres grupos de población femenina de la Ciudad de México. MATERIAL Y MÉTODOS: Estudio transversal efectuado en el año 2000, que incluyó mujeres de la Ciudad de México diagnosticadas con cáncer de mama, cáncer cervical , y mujeres de población general negativas al Papanicolaou. Todas las participantes proporcionaron su consentimiento informado para responder un cuestionario sociodemográfico y de vida sexual, y permitir la toma de una muestra sanguínea. La presencia de anticuerpos contra el virus herpes simplex tipo 2 entre las mujeres se realizó por la técnica de "Western blot"específica para el virus herpes simplex tipo 2; las asociaciones entre estos resultados y los datos de la encuesta se analizaron estadísticamente, de manera cruda y ajustada. RESULTADOS: Las mujeres concáncer cervical tuvieron una seroprevalencia de infección por el virus herpes simplex tipo 2 de 46.8% (191/408; las de población general negativas al Papanicolaou de 29.3% (214/730, y aquellas con cáncer de mama de 22.6% (29/128. Las variables asociadas significativamente a la seropositividad contra este virus fueron la edad creciente, el aumento en el número de parejas sexuales, tener cáncer cervical, y entre las mujeres con esa patología, el inicio antes de los 21 años de edad de la actividad sexual y el estar divorciadas o separadas. CONCLUSIONES: Los hallazgos observados revelaron diferencias estadísticas en la seroprevalencia del virus herpes, de acuerdo con los grupos poblacionales estudiados. La frecuencia global de la infección viral entre las participantes las sitúa en un riesgo intermedio, en comparación con otros grupos poblacionales que en México son de alto y bajo riesgo (trabajadoras sexuales y estudiantes universitarias, respectivamente, analizados en años recientes.

    Full Text Available En Bolivia no se han realizado estudios específicos sobre los virus de la hepatitis, por lo que su prevalencia y patrones de circulación son prácticamente desconocidos. De 1992 a 1996 se realizó un estudio seroepidemiológico con el fin de adquirir una primera visión de conjunto sobre las prevalencias de las infecciones por virus de la hepatitis B (VHB, C (VHC, D (VHD y E (VHE en distintas poblaciones de Bolivia. Sobre la base de los datos obtenidos en otros lugares de América Latina, se prestó atención especial al estudio de las comunidades autóctonas de la región amazónica. En las zonas rurales del altiplano andino, la infección por VHB presentó una prevalencia general que correspondería a una situación de endemia media o baja (11,2% y no se encontró ningún portador de anticuerpos contra VHC o VHD. En dos poblaciones de alto riesgo de la ciudad de Cochabamba (niños sin hogar y trabajadoras del sexo, la prevalencia de infección por VHB fue similar (11,6% y podría considerarse baja en comparación con la de otras poblaciones análogas de núcleos urbanos en América Latina. La correspondiente al VHC (un caso positivo, 0,5% sería parecida a la descrita en esas mismas poblaciones, si bien el escaso número de muestras estudiadas no permite extraer conclusiones más firmes. En concordancia con observaciones anteriores de comunidades similares de zonas tropicales de Suramérica, en las poblaciones autóctonas de la Amazonia boliviana la infección por VHB es sumamente endémica (prevalencia general de 74,0%, pero no se ha detectado la circulación de VHC. Se sabe que la transmisión de VHB es horizontal y tiene lugar desde edades muy tempranas, pero se desconocen los mecanismos de esa actividad. A los 10 años de edad, más de la mitad de la población ya ha experimentado la infección natural que, 10 años más tarde, se habrá difundido a prácticamente toda la población.

    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.

    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.

    Female genital mutilation (FGM) is illegal in the UK but nevertheless practised in some immigrant communities. Effective educational approaches are required to inform policy and to direct resources, often in the voluntary sector. The opinions in this article arise from discussions with professionals and members of FGM-practising communities. We highlight the importance of sharing experiences and expertise across health and social care professionals as well as working in partnership with culturally sensitive Non-Governmental Organisations. Enlisting the support of men and religious leaders is crucial to breaking down barriers in male-dominated communities and dispelling myths about FGM being a 'requirement' of faith.

    Full Text Available Certas moléstias de vírus e o efeito fitotóxico provocado por toxinas de alguns insetos influenciam a composição mineral das fôlhas de plantas afetadas. As alterações provocadas podem se assemelhar a deficiências minerais puramente nutricionais e, em certos casos, há realmente menor teor do elemento associado aos sintomas da moléstia. A aplicação do elemento faltante nos casos citados não provoca geralmente recuperação dos tecidos afetados, com exceção da deficiência de zinco associada à infecção de citros pela tristeza. É sugerido que a resposta à aplicação do elemento em deficiência dependerá de ser ou não esta, sintoma primário ou secundário da moléstia. É salientado que as recomendações sôbre adubação, baseadas nos resultados da diagnose foliar, deverão sempre considerar a possibilidade de não serem as deficiências constatadas resultantes sempre da falta de disponibilidade do elemento no solo, mas, possivelmente, da interferência de fatôres como a infecção por vírus, ação de toxina de inseto etc.Virus diseases or the toxicogenic effect induced by insect feeding influence the mineral content of affected plants. Some of the changes induced result in leaf deficiencies similar to those associated with lack of the available element in the soil. Application of the lacking element in most cases does not promote a favorable response with exception of the zinc deficiency associated with tristeza infection in citrus. It is suggested that the negative or positive response might depend on the symptom being primary or secondary. It is pointed out that fertilizer recommendations based on foliar diagnosis should always take into consideration that the deficiencies encountered are not necessarily theresult of lack of the available element in thesoil, but sometimes of the interference of virus diseases, insect toxins, and other factors.

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.

    2008-01-01

    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 masculin...

La encefalitis se considera una inflamación del sistema nervioso central (SNC que compromete el cerebro. Se manifiesta usualmente por cefaleas, fiebre y trastorno del estado de conciencia. Puede además manifestarse por convulsiones, cambios en la personalidad y manifestaciones obsesivas (síntomas neuropsiquiátricos. Las manifestaciones dependerán del tipo de virus y las células afectadas. La encefalitis puede ser causada por una gran variedad de agentes infecciosos incluyendo virus, bacterias, hongos y parásitos. Causas virales de encefalitis incluyen herpesvirus, arbovirus, rabia y enterovirus. Casos establecidos de bacterias incluyen Borrelia burgdorferi y rickettsia y el Mycoplasma neumoniae, al cual se atribuyen varios casos de encefalitis. Otros agentes como el hongo Coccidioides immitis e Histoplasma capsulatum pueden también generarla. Más de 100 agentes se han asociado a encefalitis. El diagnóstico de encefalitis constituye un reto para el clínico, y su etiología infecciosa usualmente se identifica entre el 40% al 70% de casos. El diagnóstico se hace con absoluta certeza sólo con una biopsia cerebral. La epidemiología depende de ciertos factores como la edad, la localización geográfica, la época del año, las condiciones climáticas y la inmunocompetencia del huésped. El tratamiento temprano puede disminuir el riesgo de muerte y las secuelas. Describimos cuatro pacientes con encefalitis y manifestaciones neuropsiquiátricas durante una epidemia de influenza, con el fin de alertar sobre esta asociación.The aim is to review the encephalitis in infants and adolescents as well as its etiology, clinical manifestation, epidemiology, physiopathology, diagnostic

    Introducción: El virus del papiloma humano es el principal factor de riesgo asociado con el desarrollo de cáncer cervical, uno de los cánceres más comunes en mujeres colombianas. En Colombia, donde las tasas de incidencia de cáncer cervical son altas, se tiene poca información acerca de la prevalencia de la infección y no se tienen datos de seguimiento sobre la persistencia o eliminación de la infección y los factores de riesgo asociados. En este reporte se presentan los resultados de la prevalencia de la infección por HPV y los factores de riesgo asociados en mujeres que tuvieron una citología normal al comienzo del estudio así como el seguimiento de 227 mujeres positivas para la infección por HPV durante un periodo de cinco años, en la ciudad de Bogotá, Colombia.

    Materiales y Métodos: 1859 mujeres con citología normal firmaron un consentimiento escrito y respondieron a un cuestionario estructurado. La presencia de HPV fue analizada mediante PCR con el uso de los iniciadores GP5+/ GP6+, que amplifican para un fragmento de 140 pb de la región L1/HPV (1 y tipificadas por medio del ensayo de EIA para la identificación de 37 diferentes tipos de HPV (2.

    Se calcularon riesgos relativos para eliminación de la infección por HPV mediante el uso de curvas de supervivencia.

    Resultados: La prevalencia de la infección fue de 14.8%; 9% de las mujeres fueron infectadas por HPV de alto riesgo, 3.1% por HPV de bajo riesgo, 2.3% por ambos tipos virales y 0.4% por HPV indeterminados. Se identificaron 32 diferentes tipos de HPV, siendo el HPV16, 58, 56, 81 y 18, los tipos mas comunes. La prevalencia de la infección por HPVs de alto riesgo entre

    Full Text Available La infección por virus Zika (VZ está afectando intensamente a los países latinoamericanos y se ha convertido en una nueva epidemia mediática. Su posible asociación con microcefalia y síndrome de Guillain-Barré motivó que la Organización Mundial de la Salud (OMS declarase el 1 de febrero de 2016 que esta epidemia constituye una emergencia de salud pública de importancia internacional. Los datos epidemiológicos muestran una incidencia creciente en países como Brasil y Colombia, y que la epidemia sigue expandiéndose por muchos otros países. Desde enero de 2007 hasta el 27 de abril de 2016, la OMS ha detectado transmisión autóctona en 55 países (en 42 de ellos ha sido el primer brote de Zika, y 1198 microcefalias y otros trastornos neurológicos en Brasil. Así mismo, durante 2015 y 2016, 13 países detectaron un incremento de los casos de síndrome de Guillain-Barré y de confirmación de VZ asociado a este. En relación a las microcefalias y otras graves alteraciones cerebrales en recién nacidos de madres afectadas por VZ, las investigaciones ya evidencian una relación causal. Clínicamente muchos casos son asintomáticos y el diagnóstico ofrece dificultades con otras arbovirosis. El control de vectores en España es prioritario, dada la existencia de Aedes albopictus (mosquito tigre. También se recomienda el diagnóstico precoz, evitar viajes a zonas endémicas, mantener relaciones sexuales protegidas y procurar que la prioridad política, que puede evitar que esta epidemia se convierta en una enfermedad endémica de alta prevalencia, no nos haga olvidar otros problemas de salud.

    Female genital tract, which includes oviduct, uterus, and vagina, is critical for female reproduction. In recent years, animal experiments using knockout mice and genetic studies on patients with female genital malformations have contributed substantially to our understanding of the molecular mechanisms in the female genital tract development. Here we review genes that are involved in various stages of female genital tract formation and development.

The competent immune system limits its spread, making it latent or subclinical, and its clinical symptoms rarely result in high mortality. It's difficult to estimate precisely its incidence in males due to the lack of epidemiological studies. In this work, the peniscopy was selected as the screening method of the subclinical disease due to its high sensitivity and low cost. General objective: to detect male carriers of the Human Papilloma Virus (HPV, possible transmitters of the virus. Material and methods: the population studied consisted of 45 men, between 18 and 60 years old, who assisted to the Dermatology Department of the Hospital

    A descriptive study of 140 patients with severe genital prolapse managed by colposacrosuspension with mesh interposition and a modified Burch colposuspension. A laparotomy was performed with mobilization of the rectum and exploration of the rectovaginal septum. Vaginally, a longitudinal incision was made in the posterior vaginal wall which was completely separated from the rectum. A perineal repair was done, whereafter a strip of Vypro (Johnson & Johnson, Brussels, Belgium) mesh was inserted from the perineum to the sacrum at S1. It was fixated to the perineum and vagina while the rectum was elevated and attached to the mesh. Where a perineal repair was deemed not necessary, the mesh extended from the mid-vagina to the sacrum. A second mesh strip was placed anteriorly of the vagina, covering the upper third of the vagina and extending to the sacrum. After closure of the pelvic peritoneum, covering the mesh, a modified Burch colposuspension was performed. Follow-up was done at 6 weeks, 6 months and yearly thereafter. The median age was 61 years with a median parity of 3. All patients presented with grade 2 (extending to the vaginal introitus) or 3 (outside the vaginal introitus) prolapse. Approximately one-third had urinary incontinence and a similar proportion complained of difficulty in defecation. All the patients underwent colposacrosuspension with the mesh extending to the perineum in 67% of the patients. A Burch colposuspension was performed in 79% of the women. Postoperatively, 97% of the patients were followed for 1-29 months with a median of 8.5 months (mean 10.2 months). Recurrent prolapse, grade 2 or 3, developed in 11 patients (8%) and 17 patients (12%) developed urinary incontinence, needing a transvaginal tape procedure. Removal of the mesh was necessary in one patient (0.7%). Colposacrosuspension for severe genital prolapse delivered satisfactory short-term results. It is, however, a major surgical procedure and elderly or compromised patients may

    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

    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.

    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.

    Full Text Available El virus de Epstein-Barr (VEB es el principal agente oncogénico linfotrópico dentro de la familia Herpesviridae y se encuentra mundialmente distribuido. La primoinfección se produce en adultos jóvenes y se manifiesta como mononucleosis infecciosa. La detección de anticuerpos anti-viral capside antigen (VCA indica infección previa o presente con VEB. Además, se observan títulos elevados de anticuerpos anti-VCA en las enfermedades neoplásicas asociadas al VEB como los linfomas, en individuos HIV-positivos. El objetivo de este estudio fue el desarrollo y puesta a punto de improntas de células P3HR1 para la detección serológica del VEB por técnicas de inmunofluorescencia indirecta (IFI. Se estimularon cultivos de células P3HR1 en crecimiento exponencial con phorbol-12-mirystoil-13-acetato, y se recolectaron alícuotas a distintos tiempos para realizar improntas. Se realizó una IFI con cada impronta usando como anticuerpo primario un suero VEB-positivo. Se observó un aumento del 11% en la expresión del VCA a las 40 horas post-estimulación, decayendo al 3.5% a las 48 horas. Estos datos fueron corroborados por ensayo de western blot con inmunodetección. La precisión intra- e inter-lote de las improntas fue evaluada para anticuerpos IgM e IgG, con sueros probados previamente por equipos para esta determinación disponibles en el mercado para el VEB y con sueros reactivos para otros miembros de la familia Herpesviridae. No se obtuvieron resultados falsos-negativos ni falsos-positivos para el VEB ni se observó reactividad cruzada con otros herpesvirus.

    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.

  13. The potential of immunostimulatory CpG DNA for inducing immunity against genital herpes: opportunities and challenges.

    Science.gov (United States)

    Harandi, Ali M

    2004-07-01

    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.

    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.

    A replication-defective herpes simplex virus (HSV)-2 vaccine, dl5-29, which is deleted for two essential early genes, UL5 and UL29, is highly immunogenic and protective in mice and guinea pigs. In a prior study, a derivative of HSV-2 dl5-29 termed dl5-29-41L, which has an additional deletion in UL41 (that encodes the virion-host shut-off protein), was more immunogenic and protective against challenge with wild-type HSV-2 in mice when compared with dl5-29. To determine if deletion of UL41 improves the efficacy of dl5-29 in protecting guinea pigs from HSV-2, animals were immunized with dl5-29, dl5-29-41L, or PBS. The geometric mean neutralizing antibody titers from the dl5-29 and dl5-29-41L recipients were comparable (10(1.97) and 10(2.19), respectively, p=0.15). After intravaginal challenge with wild-type HSV-2, the dl5-29-41L and dl5-29 recipients shed similar titers of HSV-2 from the vagina. Mean acute disease severity scores, numbers of recurrences during 3 months after infection, and latent viral loads in sacral ganglia were similar for dl5-29 and dl5-29-41L (all p values >0.05). dl5-29 and dl5-29-41L completely protected mice from lethal challenge with HSV-2 and induced virus-specific CD8(+) T cells in the spleens of the animals. Thus, dl5-29 was as immunogenic and protective as dl5-29-41L under these conditions. dl5-29 was at least 250,000-fold less virulent than parental virus by intracranial inoculation in healthy mice, and caused no disease in SCID mice. Both dl5-29-41L and dl5-29 are equally effective and immunogenic in guinea pigs, and dl5-29 is very safe in immunocompromised animals.

    Full Text Available Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID, ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with.

    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).

  19. 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.

Sin embargo, la evidencia más fuerte de que el aloreconocimiento contribuye a la protección contra la infección con el VIH-1 es aportada por un estudio de transmisión perinatal realizado en Nairobi. En este estudio la transmisión vertical se correlacionó con el grado de concordancia entre los alelos del CMH clase I entre la madre y el bebé: el máximo grado de concordancia se asoció con un 31% de incidencia de transmisión, mientras que la infección ocurrió solo en un 3% de niños que tenían el máximo grado de disparidad con su madre (2.

    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.

    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.

  4. International efforts on abandoning female genital mutilation

    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.

    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.

    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.

    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.

    2014-01-01

    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 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. OBJECTIVE 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. METHODS 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. RESULT In our study, potassium hydroxide therapy proved to be at least as effective as cryotherapy and offered the benefit of a better safety profile. CONCLUSION 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.

    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.

    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.

    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.

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

    Science.gov (United States)

    Witkin, Steven S

    2018-05-01

    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.

    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.

    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.

    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

    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.

    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.

    Provoked vestibulodynia (PVD) is characterized by the presence of vulvar touch and pain hypersensitivity. Pain with vaginal distension, which motivates treatment seeking and perpetuates distress, is frequently reported with PVD. 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.

    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.

    Full Text Available Algunas manifestaciones clínicas de la rabia, así como los resultados de experimentos con cultivos celulares y animales de laboratorio han llevado a sugerir que el virus de la rabia afecta la neurotransmisión gabaérgica. En la corteza cerebral existen diferentes tipos de neuronas que sintetizan el neurotransmisor GABA. Éstas se pueden identificar con marcadores neuronales, entre los que se destacan tres proteínas ligadoras de calcio: la parvoalbúmina (PV, la calbindina (CB y la calretinina (CR. El virus de la rabia se disemina a través de la corteza cerebral pero se desconocen sus posibles efectos citopáticos sobre las neuronas gabaérgicas. Para evaluar el efecto de la rabia sobre estas neuronas, se estudió mediante inmunohistoquímica la expresión de PV, CB y CR en la corteza frontal de ratones normales y ratones infectados con virus 'calle' o virus 'fijo' de la rabia. La PV se expresó en neuronas multipolares dispersas regularmente entre las capas II y VI, y en botones sinápticos que bordeaban el soma de las neuronas piramidales. La inmunorreactividad a CB se manifestó en dos franjas corticales: la primera, en las capas supragranulares II y III en neuronas con somas redondeados e inmersos en un neuropilo intensamente marcado; la segunda, en las capas infragranulares V y VI en neuronas multipolares dispersas y rodeadas por un neuropilo menos reactivo. La CR se expresó en neuronas bipolares con somas fusiformes distribuidas en las seis capas corticales, pero concentradas principalmente en las capas II y III. Hubo una característica común en las muestras infectadas con los dos tipos de virus: la inmunotinción a PV fue más intensa que en las muestras normales. La infección derivada del virus 'calle' no causó alteraciones adicionales en la expresión de las tres proteínas. En contraste, la infección con virus 'fijo' produjo una reducción notable del número de neuronas CB+, así como de la inmunorreactividad a CB en el

    "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.

    2012-11-01

    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.

    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.

    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.

    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.

    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.

    1976-01-01

    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.

    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.

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.

  2. Pharmacokinetics of antiretroviral drugs in anatomical sanctuary sites: the male and female genital tract.

    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

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

    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

    Full Text Available Hasta hace pocos años la infección por HIV era una contraindicación absoluta para el trasplante de órganos. Desde la introducción del HAART y el aumento de la superivencia de los pacientes, comenzó a evidenciarse alta mortalidad por enfermedades terminales hepáticas y en menor grado renales. Por estos motivos los pacientes HIV+ hoy son reconsiderados para trasplante. En el año 2008, motivada por la creciente experiencia publicada sobre trasplantes renales y hepáticos en esta población, la Sociedad Argentina de Trasplantes (SAT y la Sociedad Argentina de Infectología (SADI decidieron conformar un Grupo de Trabajo para realizar una actualización del tema y emitir recomendaciones. La reunión inicial se llevó a cabo el 4 de diciembre de 2008. La principal conclusión de esta reunión fue que el status HIV+ no era una contraindicación para recibir un trasplante de órgano sólido. Posteriormente se revisó la experiencia acumulada y la bibliografía disponible que dieron lugar al documento actual. Los pacientes HIV+ candidatos a trasplante de órganos sólidos deben cumplir con una serie de requisitos clínicos, inmunológicos, virológicos y psicosociales. La supervivencia a corto y mediano plazo de los receptores HIV+ de trasplante renal y hepático es hoy comparable a la de los pacientes HIV negativos. Todavía no existen datos suficientes como para incluir pacientes HIV+ en lista de espera para trasplante de órganos intratorácicos. Las interacciones entre los inmunosupresores y los antirretrovirales (inhibidores de proteasas en especial son muy importantes y requieren una supervisión y vigilancia estrictas de los niveles sanguíneos de inmunosupresores.

    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. Estes resultados demonstram que o isolado SV-56/90 é virulento para fêmeas soronegativas, após inoculação genital, e pode ser utilizado em estudos de patogenia e de desafio vacinal.Venereal infection of heifers

    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 Seventy five patients of recurrent genital herpes (RGH treated with oral or topical acyclovir and placebo were compared and followed for periods ranging 4 to 8 years in a prospective study. Oral acyclovir definitely helps RGH patients; it shortens healing time; postpones recurrences and instills confidence in the patients. There is sufficient evidence that RGH dies a natural death with time as seen after 8 years follow up in placebo group patients. Topical use of acyclovir cream is not as useful as believed.

    Full Text Available Objetivo: Identificar las lecciones aprendidas sobre la prevención y el control de enfermedades producidas por el mismo vector desde la comunicación en salud y comunicación de riesgo, de modo que puedan ser de utilidad para otros procesos de intervención en este campo en las regiones afectadas. Método: A partir de una revisión amplia de la literatura de los últimos 10 años se analizaron 52 documentos, entre artículos de investigación, capítulos de libro, guías gubernamentales y cartas al editor encontrados en las diferentes bases de datos especializadas. Resultados: Se encontró que aún son limitadas las investigaciones que evalúan el impacto de estas estrategias de prevención y control, en especial en el caso del Chikungunya. Asimismo, aunque se ha demostrado a nivel global que uno de los modelos recomendados para el caso del dengue, producido por el mismo vector, es COMBI –Communication for Behavioural Impact–, las intervenciones para este último caso, en gran medida, aún se fundan en el modelo de IEC –Información, Educación y Comunicación. Conclusión: Las lecciones aprendidas brindan luces para una mejor planeación de la comunicación, con anticipación a futuras epidemias, en la que los voceros oficiales y la relación con los medios de comunicación también hacen parte del éxito de estas experiencias.

    Full Text Available Three women with large, mutilating genital ulcers of long duration, destroying almost the lower half of the external genitalia, are reported. 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.

    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.

  1. In defence of genital autonomy for children.

    Earp, Brian D

    2016-03-01

    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.

    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 Objetivo: Describir las manifestaciones clínicas y hallazgos de laboratorio de una serie de casos febriles agudos con diagnóstico presuntivo de infección por el virus dengue. en Quindío (Colombia. Materiales y métodos: Se realizó un estudio de corte transversal, en pacientes con sospecha clínica de dengue en el periodo comprendido entre enero y agosto de 2013, en algunos centros hospitalarios del departamento del Quindío. Se tomaron muestras de sangre para diagnóstico de dengue, leptospira, malaria, hepatitis B, y rickettsiosis. Como pruebas confirmatorias para dengue se realizó aislamiento viral en células C6/36HT y serotipificación para dengue por RTPCR; pruebas de función hepática, cuadro hemático y niveles de citocinas. Resultados: Se caracterizaron 149 casos, de los cuales el 43% presentaron infección por dengue, 4% leptospira, 6,8% rickettsias, un caso de malaria y uno de hepatitis B. En 5 casos se logró el aislamiento del DENV2 y DENV3. Mediante la RT-PCR, se evidenció cocirculación de serotipos 2, 3, 4. Se encontró que las enzimas AST/ALT, el conteo de plaquetas, la erupción y el dolor abdominal fueron marcadores característicos de la infección por dengue, mientras la ictericia y el dolor lumbar se correlacionaron con la leptospirosis. Los valores de citocinas mostraron que la IL-10, TNF α variaron significativamente en casos con dengue frente a otros diagnósticos, y la IL-17 a presentó diferencias significativas en individuos con dengue grave. Conclusiones: El dengue se confirmó como causa etiológica importante de síndrome febril icterohemorrágico en el departamento del Quindío, pero la leptospirosis y la rickettsiosis tienen también una participación importante. Sin embargo, en el 44% de los casos fueron catalogados como síndrome febril indeterminado.

    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 In February 1994, a clinical trial by the Pediatrics AIDS Clinical Trials Group (PACTG 076 demonstrated, for the first time, that it was possible to reduce the risk of vertical transmission of human immunodeficiency virus type 1 (HIV-1 by nearly 70% by means of a triple therapeutic regimen: 1 oral zidovudine (ZDV beginning anytime between the 14th and 34th week of gestation until the end of pregnancy; 2 intravenous ZDV during pregnancy, and 3 administration of oral ZDV to neonates during the first 6 weeks of life. Later, epidemiologic studies performed in the United States of America and France showed that this regimen drastically reduced perinatal transmission in clinical practice. Since then, important strides have been made, not only in terms of treatment (new drugs and highly effective therapeutic regimens and diagnosis (tests that can measure the viral load, but also in terms of an increased understanding of the pathogenesis of perinatal transmission of HIV-1. This report contains: a a review of special considerations to be kept in mind when administering antiretroviral agents to pregnant women; b a current overview of the results of clinical and epidemiologic trials dealing with the prevention of perinatal transmission of HIV-1; c a look at the use of tests for measuring HIV-1 RNA (viral load during pregnancy; d the most recent recommendations on the use of antiretroviral chemoprophylaxis and elective cesarean section for reducing perinatal viral transmission. These recommendations apply to the United States, and other countries may prefer to use different approaches.

This difference was statistically significant (p = 0.011. 75% of infected patients had risk factors. Of these, 68.7% had CRD only factor being predominant. 6% of patients with infection were vaccinated. Conclusion: The positivity rate was similar to that observed in the previous season. There was a greater involvement among young-adult population. The CRD is the most common risk factor. Vaccine coverage was low.

    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.

    To present the findings of sarcoidosis on female genital tract. Review. Department of Obstetric and Gynecology, Silesian Hospital Opava. Overview of published findings from case studies. Sarcoidosis is a multisystem granulomatous disorder of unclear cause. It typically involves the lymph nodes of mediastinum, predominantly billateral and/or pulmonary infiltrates. We find extrapulmonary involvement in 30-50% of cases. Sarcoidosis of the female reproductive system is a rare, it represent less than 1% cases of sarcoidosis. Lesions there may affect any organ, including the vulva, vagina, cervix, uterus, fallopian tube and ovary, but also for example placenta and breast. There is also recorded the incidence of multiple localization on female genitalia. Since sarcoidosis of this area is so rare, often proceeds asymptomatic and recognized only as an incidental finding, there are mention only the case histories in literature yet.Clinical symptoms may be non-specific, often imitating a tumor, or tend to be specific, depending on the localization of disability such as perineal pain, pain in the scar after the previous birth trauma, persistent pruritus, itching, irritation, dyspareunia, menstrual cycle disorders, menorrhagia, metrorrhagia, postmenopausal bleeding, amenorrhoe, abdominal pain, endometrial polypoid lesions, recurrent or persistent serometra or discharge. The diagnosis is made up of histologically - we are demonstrating noncaseating granulomas.The therapy is difficult, there are no available official guidelines. If the lesions are clinically silent, we can observed them because they may spontaneously disappear. If we are embarking on medical therapy, we start from a local application, and if this is unsuccessful then we approach the systemic administration. Corticosteroids are the drug of choice. If we diagnose the sarcoidosis of the female genital organs we must exclude systemic disease of sarcoidosis. The prognosis of disease is good.

    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.

    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.

    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.

    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.

    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.

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.

    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. No clinical characteristic is predictive of the etiology, underlining the importance of performing a thorough microbiologic evaluation. Close association with HIV is still a major public health problem.

    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.

    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

    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

    Female genital mutilation (FGM) is a violation of human rights; yet, more than 100 million females are estimated to have undergone the procedure worldwide. There is an increased need for physician education in treating FGM. Female pelvic surgeons have a unique opportunity to treat this population of patients. Here, we depict the classification of FGM and a general approach to FGM reversal. We specifically address the procedure of type III FGM reversal, or defibulation. In this video, we first highlight the importance of the problem of FGM. Next, we present the classification of FGM using an original, simple, schematic diagram highlighting they key anatomic structures involved in the four types of FGM. We then present a simple case of reversal of type III FGM, a procedure also known as defibulation. After depicting the surgical procedure, we discuss clinical results and summarize key principles of the defibulation procedure. Our patient was a 25-year-old woman who had undergone type III FGM as a child in Somalia. She desired restoration of vaginal function. We performed a reversal, and her postoperative course was uncomplicated. By 6 weeks postoperatively, she was able to engage in sexual intercourse without dyspareunia. FGM is a problem at the doorsteps of female pelvic medicine and reconstructive surgery. Our video demonstrates a basic surgical approach that can be applied to simple cases of type III FGM presenting to the female pelvic surgeon.

    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.

    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.

    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.

    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. .

    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.

    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.

    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 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.

  10. 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.

  14. 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

    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. It is imperative that NSTD should be included in the differential diagnoses of female genital ulcers. The

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    2012-01-01

    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

    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.

    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.

    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.

    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.

    2018-03-01

    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.

    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

    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.

  10. 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.

    Background & objectives: Sexually transmitted infections (STIs) enhance the transmission of human immunodeficiency virus (HIV). Thus, screening for STIs is a routine component of primary HIV care. There are limited data for selective screening guidelines for genital mycoplasmas and Chlamydia trachomatis in HIV-infected adults. The aim of the present study was to determine the frequency of genital infections with Ureaplasma spp., Mycoplasma hominis, M. genitalium and C. trachomatis in treatment naïve asymptomatic HIV-1 - infected adults and study their association with CD4+ T-cell count. Methods: First-void urine samples were collected from 100 treatment-naïve HIV-1-infected adults and 50 healthy volunteers. C. trachomatis and M. genitalium were detected by polymerase chain reaction (PCR). Ureaplasma spp. and M. hominis were detected by both culture and PCR. Circulating CD4+ cell counts of HIV-1-infected patients were determined from peripheral blood by flow-cytometry. Results: C. trachomatis was detected in 7 per cent of HIV-1-infected adults compared to none in control population. Ureaplasma spp. and M. hominis showed infection rates of 6 and 1 per cent in the HIV group and 2 and 0 per cent in the control group, respectively. None of the individuals from the patient and control groups was tested positive for M. genitalium. A significant association was found between CD4 cell count and detection of C. trachomatis in HIV-infected adults (P = 0.01). Interpretation & conclusions: Screening of HIV-infected individuals for C. trachomatis infection could be recommended as a routine component of HIV care. The role of mycoplasmas as co-pathogens of the genitourinary tract in HIV-1 infected patients seems to be unlikely. Further longitudinal studies need to be done to confirm these findings.

    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

    Conclusiones. La mayor seropositividad se registró para las hepatitis A y E. La frecuencia de la infección simultánea con el virus de la hepatitis E y otros virus hepatótropos indica que este patógeno puede ser más frecuente de lo esperado. La circulación del genotipo 3a implica que esta enfermedad puede presentarse en forma de brote y de zoonosis en Colombia.

    Psoriasis is an autoimmune chronic inflammatory skin disease known to be triggered by streptococcal and HIV infections. However, human papilloma virus infection (HPV) as a triggering factor for the development of psoriasis has not been reported yet. We, hereby report a case of plaque type with inverse psoriasis which probably could have been triggered by genital warts (HPV infection) and discuss the possible pathomechanisms for their coexistence and its management.

    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 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.
