Yap T, Khor S, Kim JS, Kim J, Kim SY, Kern JS, Martyres R, Varigos G, Chan HT, McCullough MJ, Thomas ML, Scardamaglia L. Intraoral human herpes viruses detectable by PCR in majority of patients. Oral Dis 2020; 27:378-387. [PMID: 32609943 DOI: 10.1111/odi.13523] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 06/11/2020] [Accepted: 06/23/2020] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To identify factors which influence the intraoral prevalence of human herpes viruses (HHVs) using mucosal swabs, saliva samples and qPCR analysis. METHODOLOGY In this cross-sectional observational study, matched saliva and oral swabs were collected from a total of 115 subjects: 70 immunocompetent subjects with no mucosal abnormalities, 22 with mucosal abnormalities and 23 therapeutically immunocompromised individuals. Extracted DNA was analysed by multiplex qPCR for detection and quantification of HHVs 1-6. RESULTS At least one human herpes virus was detected in 77.1% of immunocompetent individuals with no mucosal abnormalities, with EBV the most commonly detected at 61.4%. HHV-6 was detected in 17.1%, HSV-1 in 4.3% and CMV in 1.1%. Detection was higher in saliva than in oral swabs. There was no detection of HSV-2 or VZV. Neither presence of oral mucosal abnormality nor therapeutic immunocompromise was related to increased detection of human herpes virus. CONCLUSION Commensal detection rates of EBV are high, and caution in clinical correlation of positive detection is warranted. Commensal CMV rates are low, and detection is likely to be clinically relevant. This study presents a comprehensive commensal detection rate of HHVs 1-6 by qPCR in saliva and swabs.

Abstract
Objectives To investigate whether the presence of persistent self-reported oral lesions (PSOLs) is associated with sexual behaviors and with the presence of sexually transmitted infections (STIs) in individuals aged 16–25 years in the state capitals of Brazil. Materials and Methods Data from the POP-Brazil study were analyzed. An association analysis was performed by Poisson regression with the presence of PSOLs as the outcome. The exposure variables were the age at first sexual intercourse, the number of partners, oral sex practice, and aspects of condom use for model 1, and the presence of a self-reported STI or a positive rapid test for HIV/syphilis and the presence of genital human papillomavirus (HPV) for model 2. The results were adjusted for socioeconomic variables. Results The prevalence of PSOLs was 76% higher among individuals who had two or more sexual partners in the past year (p = 0.046) and 68% higher in those who reported not using condoms for contraception (p = 0.032). The group with HIV/syphilis or self-reported STI had a 140% higher PSOL prevalence (p = 0.003). Conclusions The self-report of oral lesions in adolescents and young adults may suggest risky sexual behavior and the presence of STI. Clinical relevance It is necessary to contextualize the reality of the young person to optimize oral health care.

Abstract
BACKGROUND Herpes simplex virus (HSV) type 1 and type 2 may infect the anal region and induce aphthous ulcers. HSV-induced proctitis may be severe with fever, anal pain, anal bleeding, and diarrhea. OBJECTIVES The pathogenic agents and treatment are reviewed. MATERIALS AND METHODS A review of the current literature was performed. RESULTS The shift to later primary infections with HSV1 and changes towards more frequent oro-genital and oro-anal sex has increased the incidence of HSV1-induced primary anal infections. Due to frequent recurrences, HSV2 remains the most common cause of anal HSV infection. Anal and genital HSV infections are a risk factor for subsequent HIV infection. In case of suspicion, pathogen detection by polymerase chain reaction (PCR) should be performed and other sexually transmitted diseases should be excluded. HSV proctitis may mimic inflammatory bowel disease. Treatment should include antiviral medication as in genital herpes simplex. CONCLUSIONS HSV may induce perianal infections, anal infections and HSV proctitis. Diagnosis of HSV1 and HSV2 using PCR is recommended. Anal and genital HSV infections are a risk factor for subsequent HIV infection. The risk is higher for HSV2 infection due to more frequent recurrences.

Abstract
Recurrent herpes labialis (RHL) is an incredibly common condition, though the medical literature evaluating pediatric aspects is limited. This paper assesses prevalence and therapeutic studies of pediatric RHL as well as disease complications. A comprehensive literature search of English-language citations based on PubMed queries of selected terms was performed, with exclusion if methodology was not discussed, or if studies had 10 or fewer patients. RHL prevalence in pediatrics has been assessed by measures of point and periodic prevalence, though methodologic limitations may under- or over-estimate the true prevalence of RHL. Studies have been conducted to evaluate therapeutic safety, tolerability, and efficacy of antivirals in the pediatric population. Pediatric RHL point prevalence ranges from 0.72% to 5.2% depending on the population study and the methodologies used. Pediatric RHL carries a significant public health burden and is often implicated in patients with eczema herpeticum, erythema multiforme, reactive infectious mucositis eruptions, and hypersensitivity reactions. There are few studies that evaluate the rates of occurrence of these sequelae associated with pediatric RHL.

Abstract
BACKGROUND Herpes simplex encephalitis (HSE) after primary herpes simplex virus (HSV)-1 infection can occur in children due to inborn errors of cell-intrinsic immunity in the central nervous system. Paradoxically, symptomatic mucocutaneous HSV-1 recurrences are rare survivors of childhood HSE. T-cell-acquired immunity is thought to be involved in control of recurrent mucocutaneous HSV infection. We thus tested HSV-1-specific immunity in HSE survivors. METHODS We obtained serum and peripheral blood mononuclear cells (PBMCs) from participants a median of 13.5 years after HSE. HSV-1 and HSV-2 IgG was detected by type-specific immunoblot. PBMCs from subjects passing quality control criteria were tested using enzyme-linked immunospot assay for CD4 interferon-γ responses with an HSV-1 lysate and for CD8 responses using pooled synthetic HSV-1 peptide CD8 T-cell epitopes. Healthy adult PBMCs were used to standardize assays and as comparators. RESULTS All participants were HSV-1 seropositive. Most (23/24) HSE survivors had human leukocyte antigen class I types matching the human leukocyte antigen restriction of the pooled peptides. We detected HSV-specific CD8 T-cell responses in 14 of 24 (58%) HSE survivors and in 9 of 9 healthy HSV-1 seropositive adults. HSV-specific CD4 T-cell responses were present in all 5 HSE subjects tested and in 8 of 9 healthy adults. Response magnitudes were overlapping between subject groups. CONCLUSIONS The defects in cell-intrinsic immunity leading to failure to control primary central nervous system HSV-1 infection do not preclude the acquisition of specific immunity or the control of recurrent mucocutaneous HSV infections. The rarity and lack of severe or recurrent mucocutaneous HSV infection in survivors of childhood HSE corresponds with intact adaptive T-cell immunity.

Abstract
Background Adolescence is a period of transition to adulthood. Little is known about oral mucosal lesions (OMLs) in teenagers, in which the emergence of new habits, unfamiliar to children, could affect the type of lesions. The aim of this study was to evaluate the distribution of oral mucosal lesions (OMLs) in a wide sample of adolescents. Methods A retrospective cross-sectional study was carried out examining all medical records of adolescents (aged 13–18 years) treated at the Dental Clinic of the University of Brescia (Italy) in the period from 2008 to 2014. Cases with OMLs were selected. Data regarding age, gender, type of OML, bad habits, systemic chronic diseases were collected. Results A total of 6.374 medical records (mean age 15.2 + −1.7 years) were examined. We found 1544 cases (31.7%) of oral mucosal lesions; 36 different types of mucosal alterations were detected and the most frequent were: aphthous ulcers (18%), traumatic ulcerations (14.3%), herpes simplex virus (11%), geographic tongue (9.6%), candidiasis (5.5%), and morsicatio buccarum (4.7%). Papilloma virus lesions (1.7%), piercing-related lesions (4%), multiform erythema (0.13%), oral lichen planus (0.13%) and granular cell tumour (0.06%) were also diagnosed. Conclusions The prevalence of OMLs in adolescents are different from those in children and, in some conditions, it could increase with age.

Abstract
Nickel (Ni) is one of the most common causes of allergic contact dermatitis (ACD) and the number one allergen in the frequency of positive patch test reactions. The cellular basis of ACD is the lack of specialized T cells with regulatory function allowing for the expansion of Ni[Formula: see text] specific cytotoxic CD8+ T cells. However, Ni also exerts a number of not yet fully understood activities on cells belonging to the immune system. To this regard, an immunosuppressive activity of Ni on natural killer (NK) cells has been repeatedly suggested both in animal models and humans. Here we demonstrate that NK activity of Ni[Formula: see text] intolerant patients was significantly lower than observed in controls. Moreover, the addition of Ni[Formula: see text] sulphate to cultures of peripheral blood lymphocytes (PBL) obtained by Ni[Formula: see text] allergic patients, further depressed the NK cell activity. Finally, according to the key role exerted by NK cells in containing viral infections, we found an increased frequency of Herpesvirus 1 (HSV-1) recurrence among patients with Ni[Formula: see text] allergy. In conclusion, our results indicate that Ni[Formula: see text] allergic patients may present reduced NK cell response, this resulting in turn in increased susceptibility to viral infections. Patch testing should be considered in individuals affected by unexplained recurrences of HSV-1 infection.

Abstract
IMPORTANCE OF THE FIELD Recurrent herpes labialis (RHL) is a significant disorder with social and health consequences that affects upwards of 20 - 40% of the adult population. Docosanol is the only FDA-approved topical agent that is available over the counter for management of RHL. Its mechanism of action is unique compared with other available antiviral agents. AREAS COVERED IN THIS REVIEW The authors conducted a comprehensive search of the published preclinical and clinical literature on topical docosanol for RHL. All of the published literature relating to docosanol and its use for the management of recurrent herpes labialis was reviewed, from the first report of docosanol to 31 January 2010. WHAT THE READER WILL GAIN The objective of this review was to summarize and critically evaluate the available literature with respect to topical docosanol's mechanism, safety and efficacy in the management of RHL. TAKE HOME MESSAGE Ten percent docosanol cream is a safe and effective topical treatment for the management of RHL in immunocompetent adults, with essentially equivalent efficacy compared with other available prescription topical antiviral agents. Owing to its unique mechanism of action, there is little to no risk of developing resistance.

Abstract
There are many types of diseases associated with the oral cavity. As an adjunct to professional oral dental care, various drug delivery systems have been developed to improve the treatment or prevention of these diseases. In this manuscript, the current status of drug delivery strategies for these common orofacial diseases is reviewed. Biomineral-binding drug delivery and on-demand drug release are suggested to be considered in the future design of drug delivery systems for orofacial diseases. Apparently, this research field deserves much more attention from both pharmaceutical scientists and dental health professionals.

Abstract
Herpes Simplex Virus Type 1 (HSV-1) is a nuclear replicating enveloped virus, usually acquired through direct contact with infected lesions or body fluids (typically saliva). The prevalence of HSV-1 infection increases progressively from childhood, the seroprevalence being inversely related to socioeconomic background. Primary HSV-1 infections in children are either asymptomatic or following an incubation period of about 1 week gives rise to mucocutaneous vesicular eruptions. Herpetic gingivostomatitis typically affects the tongue, lips, gingival, buccal mucosa and the hard and soft palate. Most primary oro-facial HSV infection is caused by HSV-1, infection by HSV-2 is increasingly common. Recurrent infections, which occur at variable intervals, typically give rise to vesiculo-ulcerative lesions at mucocutaneous junctions particularly the lips (herpes labialis). Recurrent HSV-1 infection within the mouth is uncommon in otherwise healthy patients, although in immunocompromised patients, recurrent infection can be more extensive and/or aggressive. The diagnosis of common herpetic infection can usually be based upon the clinical history and presenting features. Confirmatory laboratory diagnosis is, however, required when patients are, or may be, immunocompromised.

Abstract
Reactivation of latent herpes virus has been linked to triggers of mild immunosupression, such as stress or UV-exposure. Despite having predictive value in severe immunodeficiency, the white blood cell (WBC) differential count has not been examined in relation to risk of herpes reactivation in population studies. The WBC differential count and other risk factors for herpes labialis were examined in 5687 adults (ages 18-64) from the Third National Health and Nutrition Examination Survey, who had WBC 3.5-11 x 10(6) cells mL(-1) and reported no acute infections in the past month. The association between self-reported herpes labialis in the past year and the WBC differential count was modeled, adjusting for age, sex, race/ethnicity, education, smoking, upper respiratory infections (URI), and HSV-1 antibodies. Herpes labialis was significantly associated with white race/ethnicity, being a nonsmoker, and frequent URI. Compared with the highest quartile, being in the lowest quartile of granulocytes was associated with herpes labialis, adjusted odds ratio=1.82 (95% confidence interval 1.20, 2.28). At the same time, there was a trend towards an inverse association of lower lymphocyte count and herpes labialis. These findings suggest that moderate differences in the WBC differential count are related to reactivation of HSV-1. Prospective studies may help to show whether such differences indicate susceptibility to loss of latency or represent a consequence of reactivated infection.

Abstract
A biomineral-binding alendronate-beta-cyclodextrin conjugate (ALN-beta-CD, Fig. 1) was developed as a novel drug delivery system. "Click" chemistry was used in conjugation of alendronate (ALN) to beta-cyclodextrin (beta-CD). The delivery system shows very strong binding to hydroxyapatite (HA, main component of tooth enamel). Its ability in forming molecular inclusion complex with dexamethsone (Dex, model drug) was investigated independently with phase solubility experiments, isothermal titration calorimetry (ITC), Job plot and (1)H NMR. The stoichiometry of ALN-beta-CD/Dex molecular complex was determined as 1:1, and the binding constant of the complex obtained from ITC study is 3.8 x 10(3) M(-1), which is similar to the binding constant of beta-CD/Dex. In vitro data indicate that the ALN-beta-CD/Dex complex bound to HA could gradually release Dex upon repeated extraction with phosphate buffer saline (PBS). This novel drug delivery system may have great potential in improving treatment of diseases in the oral cavity.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of oral lesions in 13- to 16-year-old students. METHODS A cross-sectional survey was carried out on students in Duzce, a province in the western Black Sea region of Turkey. A total of 993 children aged between 13 and 16 from eight secondary schools were examined. Oral lesions with recurrent behavior, if observed, were recorded at the time of examination. Venous blood samples were obtained for detecting hemoglobin levels. RESULTS Two hundred sixty adolescents (26.2%) were diagnosed with at least one oral mucosal lesion at the time of the examination. Thirteen different mucosal alterations were diagnosed, and the most common lesions were angular cheilitis (9%), linea alba (5.3%), and aphthous ulceration (3.6%). The correlation between occurrence of mucosal lesions and sex was not statistically significant (P > 0.05). Statistical evaluation of the data revealed a significant relationship only between the presence of angular cheilitis and anemia (P < 0.05). CONCLUSION This study is the first epidemiologic study of oral mucosal lesions in adolescents in Turkey. Angular cheilitis was the only oral mucosal lesion that had a significant correlation with anemia.
