RESUMO

BACKGROUND: For women living with HIV (WLHIV), co-infection with herpes simplex virus type 2 (HSV-2) causes severe genital ulcers and presents additional challenges for their HIV care. To inform preventive strategies, we aimed to determine the incidence and risk factors of HSV-2 positivity in a prospective cohort of South African women. METHODS: The CAPRISA 002 study enrolled women at acute HIV infection between 2004 and 2020. HSV-2 testing was conducted by multiplex polymerase chain reaction (PCR) assay on collected vaginal swabs up to twice annually during follow-up. We calculated incidence as the number of new cases per 100 person-years (PYs) and used Cox-proportional-hazard regression to identify factors associated with time-to-HSV-2 PCR positivity. RESULTS: At enrolment, the median age of 171 women was 24 years, interquartile range (IQR 21-28), and the estimated median days since HIV infection was 42 (IQR 22-65). Of participants tested at enrolment, HSV-2 antibody prevalence was 81.4% (105/129), and 10.6% (12/113) were positive by PCR. Among 147 women with a prior negative HSV-2 PCR diagnosis, we observed 47 new HSV-2 PCR positive cases over 424.4 PYs of follow-up, yielding an incidence rate of 11.1 cases per-100-PYs. HSV-2 PCR positivity incidence was higher among younger women (<25 years: adjusted Hazard Ratio [aHR] = 5.91, 95%CI 3.02-11.6), those with bacterial vaginosis (BV) (Nugent score 7-10: aHR = 2.17, 95%CI 1.15-4.10) and lower CD4 counts (<500 cells/µl: aHR = 2.04, 95%CI 1.08-3.87). CONCLUSION: After acute HIV infection in women, the incidence of HSV-2 PCR positivity was associated with younger age, BV diagnosis and lower CD4 count.

RESUMO

The myriad presentations of ulcerative sexually transmitted infections, other than genital herpes and syphilis, challenge even the most astute clinician given the considerable overlap in clinical presentation and lack of widely available diagnostic resources, such as nucleic acid testing, to confirm the diagnosis. Even so, case prevalence is relatively low, and incidence of chancroid and granuloma inguinale are declining. These diseases still cause substantial morbidity and increased chance for HIV acquisition, and with the recent advent of mpox as a cause, it remains imperative to identify and treat accurately.

RESUMO

OBJECTIVES: To examine innate immunity predictors of HIV-1 acquisition as biomarkers of HSV-2 risk and biological basis for epidemiologically established HIV-1 predisposition in HSV-2 infected women. METHODS: We analysed longitudinal samples from HIV-1 negative visits of 1019 women before and after HSV-2 acquisition. We measured cervical and serum biomarkers of inflammation and immune activation previously linked to HIV-1 risk. Protein levels were Box-Cox transformed and ORs for HSV-2 acquisition were calculated based on top quartile or below/above median levels for all HSV-2 negative visits. Bivariate analysis determined the likelihood of HSV-2 acquisition by biomarker levels preceding infection. Linear mixed-effects models evaluated if biomarkers differed by HSV-2 status defined as negative, incident or established infections with an established infection cut-off starting at 6 months. RESULTS: In the cervical compartment, two biomarkers of HIV-1 risk (low SLPI and high BD-2) also predicted HSV-2 acquisition. In addition, HSV-2 acquisition was associated with IL-1ß, IL-6, IL-8, MIP-3α, ICAM-1 and VEGF when below median levels. Systemic immunity predictors of HSV-2 acquisition were high sCD14 and IL-6, with highest odds when concomitantly increased (OR=2.23, 1.49-3.35). Concomitant systemic and mucosal predictors of HSV-2 acquisition risk included (1) serum top quartile sCD14 with cervical low SLPI, VEGF and ICAM-1, or high BD-2; (2) serum high IL-6 with cervical low VEGF and ICAM-1, SLPI, IL-1ß and IL-6; and (3) serum low C reactive protein with cervical high BD-2 (the only combination also predictive of HIV-1 acquisition). Most cervical biomarkers were decreased after HSV-2 acquisition compared with the HSV-2 negative visits, with incident infections associated with a larger number of suppressed cervical biomarkers and lower serum IL-6 levels compared with established infections. CONCLUSIONS: A combination of systemic immunoinflammatory and cervical immunosuppressed states predicts HSV-2 acquisition. A persistently suppressed innate immunity during incident HSV-2 infection may add to the increased HIV-1 susceptibility.

RESUMO

Reproductive tract infections have long been hypothesized to be risk factors for development of uterine fibroids, but few studies have investigated the issue. In our 2016 cross-sectional analysis from the Study of Environment, Lifestyle and Fibroids (2010-2018), a large Detroit, Michigan, community-based cohort study of 23- to 35-year-old African-American women with ultrasound fibroid screening, we found no association between a very prevalent reproductive tract infection, herpes simplex virus type 2 (HSV-2), and fibroids. With prospective data from the cohort (ultrasounds performed every 20 months over 5 years), we examined HSV-2's associations with fibroid incidence (among 1,208 women who were fibroid-free at baseline) and growth (among women with fibroids at baseline or diagnosed during the study). Using Cox proportional hazards models, we computed adjusted hazard ratios and 95% confidence intervals for fibroid incidence comparing HSV-2-seropositive women with HSV-2-seronegative women. The influence of HSV-2 infection on growth was assessed on the basis of the difference in fibroid size between successive ultrasounds (1,323 growth measures) using a linear mixed model, estimating the percent difference in growth scaled to 18 months. HSV-2 seropositivity was not associated with fibroid incidence (adjusted hazard ratio = 0.88, 95% confidence interval: 0.69, 1.12) or growth (estimated growth difference = 3.1%, 95% confidence interval: -5.8, 13.0). Women can be reassured that HSV-2 infection is unlikely to increase their risk of fibroid-related health problems, given these longitudinal measures.

RESUMO

Viral infections have haunted humankind since times immemorial. Overpopulation, globalization, and extensive deforestation have created an ideal environment for a viral spread with unknown and multiple shedding routes. Many viruses can infect the male reproductive tract, with potential adverse consequences to male reproductive health, including infertility and cancer. Moreover, some genital tract viral infections can be sexually transmitted, potentially impacting the resulting offspring's health. We have summarized the evidence concerning the presence and adverse effects of the relevant viruses on the reproductive tract (mumps virus, human immunodeficiency virus, herpes virus, human papillomavirus, hepatitis B and C viruses, Ebola virus, Zika virus, influenza virus, and coronaviruses), their routes of infection, target organs and cells, prevalence and pattern of virus shedding in semen, as well as diagnosis/testing and treatment strategies. The pathophysiological understanding in the male genital tract is essential to assess its clinical impact on male reproductive health and guide future research.

RESUMO

Herpes Simplex Virus (HSV) is the leading cause of genital ulcers worldwide. In Human Immunodeficiency Virus (HIV) co-infected individuals, rare hypertrophic pseudo-tumoral forms have been described as simulating squamous cell carcinoma or other viral infections such as those caused by Varicella zoster, Molluscum contagiosum and HPV induced lesions. Here, we report a case of hypertrophic genital herpes in an HIV-infected patient effectively treated with surgery and topical 5% imiquimod after the recurrence of lesions. A 45-year-old woman, HIV-positive for 17 years and on regular antiretroviral therapy, presented with a painful 2cm vulvar sessile lesion, a 1cm ulcerated lesion on the clitoral hood, and a slightly elevated lesion in the middle third of the tongue. Excisional biopsy and surgical removal of lesion were performed for histopathological exam. Histopathology of genital lesions showed evidence of chronic lymphoplasmacytic inflammation, intense ulcerated plasmacytosis, and squamous cells displaying HSV cytopathogenic effect. After three months, the patient presented with a new ulcerated perineal lesion. Histopathology showed evidence of chronic ulcerative-vegetative herpetic dermatitis. Consequently, topical 5% imiquimod was administered with successful results. Relapsing character and atypical genital disease evolution with an exophytic pseudotumoral injury have been noted in patients co-infected with HIV and HSV, necessitating anatomopathological recognition for diagnostic confirmation and exclusion of malignancy. Local immunotherapy should be considered as treatment approach.

RESUMO

A 37-yr-old patient previously diagnosed with human immunodeficiency virus initially presented with a genital lesion which upon histologic assessment was diagnosed as a pseudotumor associated with herpes simplex virus infection. The pseudotumor responded to initial treatment with Acyclovir, however, the lesion recurred 2 yr later and was diagnosed as plasma cell vulvitis. We discuss the clinical presentation, diagnostic work up and treatment options of such a rare lesion.

RESUMO

We present the PET/CT findings of extensive disseminated genital herpes simplex virus infection in a 29-year-old woman known with disseminated anaplastic lymphoma kinase-mutated nonsmall lung cancer. PET/CT revealed extensive involvement of the outer and inner genitalia, multiple lymph nodes extending from the porta hepatis to the groins, and involvement of the liver. Disseminated herpes simplex virus infection is well described in neonates and immunocompromised individuals but very rare in immunocompetent adults as was the case with this patient.

RESUMO

BACKGROUND: Our objective was to assess the population-level association between herpes simplex virus 2 (HSV-2) and HIV prevalence. METHODS: Reports of HSV-2 and HIV prevalence were systematically reviewed and synthesized following PRISMA guidelines. Spearman rank correlation ((Equation is included in full-text article.)) was used to assess correlations. Risk ratios (RRHSV-2/HIV) and odds ratios (ORHSV-2/HIV) were used to assess HSV-2/HIV epidemiologic overlap. DerSimonian-Laird random-effects meta-analyses were conducted. RESULTS: In total, 939 matched HSV-2/HIV prevalence measures were identified from 77 countries. HSV-2 prevalence was consistently higher than HIV prevalence. Strong HSV-2/HIV prevalence association was found for all data ((Equation is included in full-text article.) = 0.6, P < 0.001), all data excluding people who inject drugs (PWID) and children ((Equation is included in full-text article.) = 0.7, P < 0.001), female sex workers ((Equation is included in full-text article.) = 0.5, P < 0.001), and MSM ((Equation is included in full-text article.) = 0.7, P < 0.001). No association was found for PWID ((Equation is included in full-text article.) = 0.2, P = 0.222) and children ((Equation is included in full-text article.) = 0.3, P = 0.082). A threshold effect was apparent where HIV prevalence was limited at HSV-2 prevalence less than 20%, but grew steadily with HSV-2 prevalence for HSV-2 prevalence greater than 20%. The overall pooled mean RRHSV-2/HIV was 5.0 (95% CI 4.7-5.3) and ORHSV-2/HIV was 9.0 (95% CI 8.4-9.7). The RRHSV-2/HIV and ORHSV-2/HIV showed similar patterns that conveyed inferences about HSV-2 and HIV epidemiology. CONCLUSION: HSV-2 and HIV prevalence are strongly associated. HSV-2 prevalence can be used as a proxy 'biomarker' of HIV epidemic potential, acting as a 'temperature scale' of the intensity of sexual risk behavior that drive HIV transmission. HSV-2 prevalence can be used to identify populations and/or sexual networks at high-risk of future HIV expansion, and help prioritization, optimization, and resource allocation of cost-effective prevention interventions.

RESUMO

Background: Human immunodeficiency virus (HIV) and herpes simplex virus type 2 (HSV2) are strongly associated, although mechanisms are not fully understood. An HIV prevention trial allowed reexamination of this association at individual and community levels. Methods: The HIV Prevention Trials Network 071 (PopART) study evaluates a combination prevention intervention in 21 urban communities in Zambia and South Africa. To measure impact on HIV infection incidence, a cohort of approximately 2000 adults (age range, 18-44 years) was selected randomly from each community. Baseline data on sociodemographic characteristics, behavior, and HIV/HSV2 serologic findings were used to examine the association between HIV and HSV2. At the community level, HIV prevalence was plotted against HSV2 prevalence. Results: A total of 38691 adults participated. HSV2 prevalence among women and men was 50% and 22%, respectively, in Zambia and 60% and 27%, respectively, in South Africa. Estimated HSV2 infection incidence among those aged 18-24 years was 8.06 cases/100 person-years (95% confidence interval [CI], 6.76-9.35) and 1.76 cases/100 person-years (95% CI, 1.30-2.22) among women and men, respectively. A 6-fold higher odds of HIV infection was seen in HSV2-infected individuals in both sexes, after adjustment for confounders (odds ratio, 6.66 [95% CI, 6.07-7.31] among women and 6.57 [95% CI, 5.56-7.77] among men). At the community-level, there was a strong linear relationship between HIV and HSV2 prevalence (ρ = 0.92; P < .001). Conclusions: There was an exquisite association between these 2 infections, at the individual and community levels, likely due in part to a powerful cofactor effect of HSV2 on HIV transmission. HSV2 control could contribute to HIV prevention.

RESUMO

BACKGROUND: In South Africa, treatment of genital ulcer disease (GUD) occurs in the context of syndromic management. GUD aetiological studies have been conducted in Johannesburg since 2007. We report on GUD pathogen prevalence, sero-prevalence of STI co-infections and aetiological trends among GUD patients presenting to a community-based primary healthcare facility in Johannesburg over a 9-year period. METHODS AND FINDINGS: GUD surveys were conducted from January to April each year. Consecutive genital ulcers were sampled from consenting adults. Swab-extracted DNA was tested by multiplex real-time PCR assays for herpes simplex virus (HSV), Treponema pallidum (TP), Haemophilus ducreyi (HD) and Chlamydia trachomatis (CT). HSV-positive DNA extracts were further subtyped into HSV-1 and HSV-2 using a commercial PCR assay; CT-positive extracts were tested with an in-house PCR assay specific for serovars L1-L3 (lymphogranuloma venereum). Sera were tested for HIV, HSV-2, and syphilis co-infections. Giemsa-stained ulcer smears were screened for Klebsiella granulomatis by microscopy. Data were analysed with STATATM version 14. Of 771 GUD specimens, 503 (65.2%) had a detectable pathogen: HSV 468 (60.7%); TP 30 (3.9%); CT L1-3 7 (0.9%); HD 4 (0.5%). No aetiological agents were detected in 270 (34.8%) ulcer specimens. Seroprevalence rates were as follows: HIV 61.7%; HSV-2 80.2% and syphilis 5.8%. There was a strong association between GUD pathogen detection and HIV seropositivity (p < 0.001); 68% of cases caused by HSV were co-infected with HIV. There was a significant decline in the relative prevalence of ulcer-derived HSV over time, predominantly from 2013-2015 (p-value for trend = 0.023); and a trend towards a decrease in the HIV seropositivity rate (p-value for trend = 0.209). CONCLUSIONS: HSV remains the leading cause of pathogen-detectable GUD in South Africa. The prevalence of HIV co-infection among GUD patients is high, underlining the importance of linkage to universal HIV testing and treatment in primary healthcare settings.

RESUMO

Herpes zoster (HZ) is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus (VZV) (1). It is a frequent medical condition with an incidence rate of 2-3 cases per 1000 person/years in the general population and 7-10 cases per 1000 person/years after the age of 50 (1,2). Risk factors and triggers for reactivation of HZV have not yet been determined precisely, but are likely to include malignancies, immune deficiencies, solid organ and bone marrow transplant recipients, autoimmune diseases, psychological conditions, emotional stress, human immunodeficiency virus (HIV) infection, and other patients receiving immunosuppressive therapies (1,3). A 24-year-old IV drug user presented with grouped clusters of vesicles and erosions on an erythematous, edematous base distributed on the left side of the penile shaft and the left infraumbilical region (Figure 1, a and b), with regional lymphadenopathy. He had prodromal symptoms of pain, dysesthesia and burning a few days prior to the appearance of the skin lesion. The patient reported unprotected sexual contacts a few months before the eruptions. The unilateral distribution was highly suggestive of herpes zoster. A Tzanck smear was performed by obtaining scrapings from the base of a fresh vesicular lesion after it had been unroofed; it showed the characteristic presence of multinucleated giant cells that suggested herpes infection. Polymerase chain reaction (PCR) analysis of vesicular fluid yielded positive results for VZV. A 7-day course of acyclovir (800 mg 5 times a day) was initiated. The patient reported marked improvement on the second day of antiviral therapy. The course was uncomplicated, and the lesions healed without postherpetic neuralgia. Serologic tests for syphilis (VDRL/RPR and TPHA) and hepatitis C and B serologic tests were negative, but HIV test (enzyme immunoassays (EIA) for HIV-1 and HIV-2 antibodies were positive, which was later confirmed with Western blot (WB) tests. Because of the positive HIV test, the patient was referred to the Clinic for Infectious Diseases for further treatment. Herpes zoster is painful vesicular skin eruption with unilateral dermatomal involvement, usually with a severe impact on the quality of life in affected patients (1). The risk for developing HZ during a lifetime in patients exposed to VZV infection is 10-30% (4). However, the risk is higher in immunocompromised patients, particularly in cancer patients and HIV-positive patients (1,5,6). HZ is seen approximately 7 times more frequent in patients with HIV infection (5). Reactivated VZV infection may occur at any stage of HIV infection and may be the first clinical evidence of HIV infection. The development of HZ in immunocompromised individuals can be explain by decline in cell-mediated immunity and CD4 count (6). HZ predominantly affects the thoracic region, followed by the head, cervical, and lumbar regions (1). Sacral dermatomes are involved in only up to 2% of cases (1). HZ involving the penis is rarely reported, with only few case reports in the literature (3,7-9). Birch et al. compared VZV and herpes simplex virus (HSV) in specimens obtained from the genital lesions of adults presenting with presumed genital herpes infection (10). They found VZV in nearly 3% of virus-positive genital specimens, which demonstrates that this virus needs to be considered in the differential diagnosis of genital herpetic lesions (10) and that it is possible that genital HZ infection is underdiagnosed. Tzanck smear is a rapid and inexpensive method, but it cannot differentiate VZV from HSV. Genital HZ could be mistaken for zosteriform HSV infection, so a PCR test should be performed to confirm the underlying diagnosis (1). Genital forms of HZ are rare and sometimes clinically difficult to diagnose, especially when the typical zosteriform distribution is lacking; PCR testing is therefore suggested. HZ is considered a possible HIV indicator; an HIV test should therefore be performed. According to our knowledge and literature search, this is the first case report of penile HZ in an HIV-positive patient.

RESUMO

The specific histopathologic diagnosis of a primary acantholytic disorder takes into account the distribution and extent of acantholysis, presence or absence of dyskeratosis, nature of the dermal inflammatory cell infiltrate, and immunofluorescence findings. Herpes virus infection is a common cause of secondary acantholysis where distinctive viral cytopathic changes aid in making it a clear-cut diagnosis in majority of cases. We present a case of coexistence of Hailey-Hailey disease and herpes simplex virus infection to compare and contrast their histopathologic features. This is imperative because acantholytic cells from primary acantholytic disorders may occasionally show cytological features traditionally associated with herpes virus infection (pseudoherpetic changes). The objective of this article is to create a greater awareness of pseudoherpetic changes and also to explore the clinical significance of coexistence of a primary acantholytic disorder and herpes virus infection, as in this case.

RESUMO

BACKGROUND Human herpesvirus 2 (HHV-2) have DNA genome with a limited genetic variability and have been classified into two clades. OBJECTIVES To identify and characterise six HHV-2 isolates derived from Brazilian women. METHODS HHV-2 isolates were performed polymerase chain reaction (PCR) and sequencing of 2250 pb of the glycoprotein B (gB) coding regions. FINDINGS Four HHV-2 isolates were classified into clade B, while the remaining two, derived from HIV-1 co-infected women, showed a notable genetic divergence (> 1%). MAIN CONCLUSION The results reveal novel HHV-2 variants. The impact of these novel variants on HHV-2 pathogenesis and HIV/HHV-2 coinfection need to be investigated.

RESUMO

Preterm birth (PTB), or birth before 37 weeks gestation, is the leading cause of neonatal mortality worldwide. Cervical viral infections have been established as risk factors for PTB in women, although the mechanism leading to increased risk is unknown. Using a mouse model of pregnancy, we determined that intra-vaginal HSV2 infection caused increased rates of preterm birth following an intra-vaginal bacterial infection. HSV2 infection resulted in histological changes in the cervix mimicking cervical ripening, including significant collagen remodeling and increased hyaluronic acid synthesis. Viral infection also caused aberrant expression of estrogen and progesterone receptor in the cervical epithelium. Further analysis using human ectocervical cells demonstrated a role for Src kinase in virus-mediated changes in estrogen receptor and hyaluronic acid expression. In conclusion, HSV2 affects proteins involved in tissue hormone responsiveness, causes significant changes reminiscent of premature cervical ripening, and increases risk of preterm birth.
