Uncommon cause of trigeminal neuritis and central nervous system involvement by herpes labialis: a case report.

BACKGROUND: Trigeminal neuropathy is characterized by numbness in the region innervated by the trigeminal nerves, with or without neuropathic weakness in the muscles of mastication. Trigeminal neuritis is a form of trigeminal neuropathy in which the lesion is caused by an inflammation. Herein, we report a patient with trigeminal neuritis due to central nervous system (CNS) involvement of herpes labialis (HL) infection, which was successfully treated with anti-viral and anti-inflammatory agents. CASE PRESENTATION: A young healthy female presented with numbness in the left hemiface for two weeks. She had a preceding typical HL infection on left facial lip one week before the sensory symptom onset. Brain magnetic resonance imaging revealed high signal intensities and asymmetrical thickening with enhancement along the cisternal segment of the left trigeminal nerve. Additionally, brain MR angiography showed multifocal stenoses in the M1 segment of the middle cerebral artery and the cavernous portion of the internal carotid artery. Cerebrospinal fluid (CSF) examination showed mild pleocytosis with normal protein level, glucose ratio, but CSF polymerase chain reaction assay for specific anti-viral antibodies including herpes simplex virus was negative, and CSF culture also did not identify a specific pathogen. The results of serologic testing including tumor markers and autoimmune markers were all unremarkable. A tentative diagnosis of trigeminal neuritis as a complication of HL involving the CNS was made considering the clinical, neuroradiological, and laboratory findings of the patient. Therefore, the patient was treated with intravenous methylprednisolone and acyclovir for 10 days. After the treatments, her sensory disturbance was markedly improved. Brain MRI at the 3-month follow-up also demonstrated improvement of previously identified high signal intensity lesions and multifocal intracerebral artery stenoses. CONCLUSION: HL is usually a self-limiting, benign disease without complications, but rarely presents as trigeminal neuritis due to CNS involvement. Therefore, meticulous evaluation may be necessary if trigeminal neuritis or CNS involving symptoms occur after HL.

Treatment of herpes labialis by photodynamic therapy: Study protocol clinical trial (SPIRIT compliant).

BACKGROUND: Lesions of herpes labialis are caused by the herpes simplex virus type 1 and cause pain and aesthetic compromise. It is characterized by the formation of small vesicles that coalesce and rupture forming extremely painful ulcers, that evolve to crusts, dry desquamations until their complete remission. Currently the treatment of these lesions is done with acyclovir. Although it diminishes the symptomatology, it causes viral resistance and does not prevent the recurrence of the lesions. It is known that antimicrobial photodynamic therapy (aPDT) has numerous advantages, among them: the reduction of the time of remission, and does not cause resistance. This protocol will determine the effectiveness of PDT in lesions of herpes labialis. MATERIALS AND METHODS: A total of 30 patients with herpes labialis in the prodromal stage of vesicles, ulcers, and crusts will be selected to participate in the study and randomized into 2 groups: G1 control and G2 experimental. After signing Research Ethics Committee and TA, patients in group G1 will undergo the standard gold treatment for herpes labialis with acyclovir and simulated PDT treatment. Patients in the experimental G2 group will be treated simulating the gold standard treatment of herpes labialis (placebo) and PDT. In all patients, saliva samples will be collected for analysis of cytokines, and will be performed exfoliative cytology in the lesions. The pain will be assessed through a pain scale and a questionnaire of quality of life related to oral health (OHIP-14) will be given to them. Patients will continue to be followed up after 7 days, 1 month, 3 months, and 6 months; if there is a recurrence of the lesion, they will contact the researchers.Clinical registration: clinicaltrials.gov - NCT04037475.

Decreased Labial Herpes Simplex Virus Outbreaks Following Botulinum Neurotoxin Type A Injection: A Case Report.

Herpes Labialis results from reactivation of latent herpes simplex virus (HSV-1 or HSV-2) harbored in the trigeminal ganglion during times of psychological stress, cutaneous injury or photo exposure. Following reactivation, the virus is anterogradely transported through axonal termini to the skin where the virus is released and replicates causing a clinical outbreak. Botulinum neurotoxin A (BoNTA) is known to inhibit presynaptic neuropeptide and neurotransmitter release. Whether it has the capacity to interfere with viral shedding and delivery into the skin remains unclear. We were interested in determining whether BoNTA could serve as a potential therapeutic or prophylactic treatment approach for frequent and severe HSV recurrences. We describe a clinical case report in which a patient successfully maintained a sustained absence of HSV outbreaks in regions where BoNTA was intradermally administered. BoNTA may offer a novel therapeutic approach for preventing recurrent HSV disease. J Drugs Dermatol. 2018;17(10):1127-1129.

Protocol for a randomised controlled trial of 90% kanuka honey versus 5% aciclovir for the treatment of herpes simplex labialis in the community setting.

INTRODUCTION: Worldwide, about 90% of people are infected with the herpes simplex virus, 30% of whom will experience recurrent herpes simplex labialis, commonly referred to as 'cold sores', which can last up to 10 days. The most common treatment is aciclovir cream which reduces healing time by just half a day compared with no specific treatment. This is a protocol for a randomised controlled trial (RCT) to determine the efficacy of medical grade kanuka honey-based topical treatment (Honevo) in reducing the healing time and pain of cold sores, compared with topical aciclovir treatment (Viraban). METHODS AND ANALYSIS: This open-label, parallel-group, active comparator superiority RCT will compare the efficacy of medical grade kanuka honey with 5% aciclovir cream in the treatment of cold sores in the setting of a pharmacy research network of 60 sites throughout New Zealand. Adults presenting with a cold sore (N=950) will be randomised by pharmacy-based investigators. The pharmacy-based investigators will dispense the investigational product to randomised participants and both study groups apply the treatment five times daily until their skin returns to normal or for 14 days, whichever occurs first. In response to a daily SMS message, participants complete an assessment of their cold sore healing, with reference to a visual guide, and transmit it to the investigators by a smartphone eDiary in real time. The primary outcome variable is time (in days) from randomisation to return to normal skin. Secondary endpoints include total healing time stratified by stage of the lesion at onset of treatment, highest pain severity and time to pain resolution. ETHICS AND DISSEMINATION: New Zealand Ethics Registration 15/NTB/93. Results will be published in a peer-reviewed medical journal, presented at academic meetings and reported to participants.

Diagnosis of HIV-Associated Oral Lesions in Relation to Early versus Delayed Antiretroviral Therapy: Results from the CIPRA HT001 Trial.

Oral mucosal lesions that are associated with HIV infection can play an important role in guiding the decision to initiate antiretroviral therapy (ART). The incidence of these lesions relative to the timing of ART initiation has not been well characterized. A randomized controlled clinical trial was conducted at the GHESKIO Center in Port-au-Prince, Haiti between 2004 and 2009. 816 HIV-infected ART-naïve participants with CD4 T cell counts between 200 and 350 cells/mm3 were randomized to either immediate ART initiation (early group; N = 408), or initiation when CD4 T cell count was less than or equal 200 cells/mm3 or with the development of an AIDS-defining condition (delayed group; N = 408). Every 3 months, all participants underwent an oral examination. The incidence of oral lesions was 4.10 in the early group and 17.85 in the delayed group (p-value <0.01). In comparison to the early group, there was a significantly higher incidence of candidiasis, hairy leukoplakia, herpes labialis, and recurrent herpes simplex in the delayed group. The incidence of oral warts in delayed group was 0.97 before therapy and 4.27 post-ART initiation (p-value <0.01). In the delayed group the incidence of oral warts post-ART initiation was significantly higher than that seen in the early group (4.27 versus 1.09; p-value <0.01). The incidence of oral warts increased after ART was initiated, and relative to the early group there was a four-fold increase in oral warts if ART was initiated following an AIDS diagnosis. Based upon our findings, candidiasis, hairy leukoplakia, herpes labialis, and recurrent herpes simplex indicate immune suppression and the need to start ART. In contrast, oral warts are a sign of immune reconstitution following ART initiation.

Interferon Lambda 4 Genotype Is Not Associated with Recurrence of Oral or Genital Herpes.

IFNL4-ΔG/TT (rs368234815) genotype is associated with hepatitis C virus clearance and may play a role in other infections. IFN-λ4 protein is generated only in individuals who carry the IFNL4-ΔG allele. The IFNL4 rs12979860-T allele, which is in strong linkage disequilibrium with IFNL4-ΔG, was recently reported to be associated with more frequent and severe oral herpes episodes. We investigated the association of IFNL4-ΔG/TT with herpes simplex virus (HSV)-related outcomes among 2,192 African American and European American participants in the Women's Interagency HIV Study (WIHS). WIHS is a prospective cohort study of human immunodeficiency virus (HIV)-infected and at-risk women that began in 1994. This report includes follow-up through 2013. Available data included: HSV-1 and HSV-2 antibodies at study entry; bi-annually ascertained episodes of (self-reported) oral herpes, (self-reported) genital sores and (clinician-observed) genital ulcers; HSV-2 DNA in cervicovaginal lavage (CVL) specimens. IFNL4-ΔG/TT genotyping was determined by TaqMan. We compared women with IFNL4-ΔG/ΔG or IFNL4-TT/ΔG genotypes (i.e., IFNL4-ΔG carriers) to those with the IFNL4-TT/TT genotype, adjusting for age, race and HIV status. For outcomes with repeated measurements, the adjusted odds ratio (aOR), 95% confidence interval [CI] and p-value were determined using a generalized estimating equations approach. Median participant age at enrollment was 36 years; 81% were African American, 74% were HIV-infected. Among 1,431 participants tested for antibodies, 72.8% were positive for HSV-1 and 79.0% were positive for HSV-2. We observed no association between IFNL4-ΔG/TT genotype and any outcome: HSV-1 or HSV-2 antibody prevalence (p>0.1, all comparisons); oral herpes (aOR, 1.2; p = 0.35); genital sores (aOR, 1.0; p = 0.71); genital ulcers (aOR, 1.1; p = 0.53); detectable HSV-2 DNA in CVL (N = 322; aOR, 0.71; p = 0.49); HSV-2 DNA level (p = 0.68). In this large prospective study, IFNL4-ΔG/TT genotype was not associated with HSV-related outcomes, including episodes of oral or genital herpes.

[Using cycloferon in the complex treatment of herpetic infection in patients with atopic dermatitis].

Clinical efficacy of including cycloferon liniment in combined treatment of herpetic infection in a group of 40 patients with atopic dermatitis has been analyzed. It is concluded that the administration of cycloferon favors dynamic disappearance of general infectious syndrome, reduces timeline of rash as well as length of local inflammation, accelerates epithelization of erosions (on the average 1.2 - 1.4 times, p < 0.05), decreases frequency of recurrent infections, and reduces the level of pro-inflammatory cytokines in the blood of patients.

Herpes simplex primo-infection in an immunocompetent host with eosinophilic esophagitis.

Eosinophilic esophagitis and herpes simplex esophagitis are separately well-described entities, but their simultaneous occurrence may pose a special challenge to the clinician, especially regarding the optimal therapeutic approach. The following case report describes a patient with a history of cow's milk and dairy products intolerance, but without an underlying immunologic defect, in whom eosinophilic esophagitis was diagnosed in the course of primary herpes simplex virus 1 (HSV1) infection that clinically presented as herpes labialis and severe esophagitis. The diagnosis was confirmed by a polymerase chain reaction from cytological brush and by immunohistochemical staining that detected the presence of HSV1 DNA in esophageal mucosa, and histologically by persistent eosinophil-predominant inflammation, typical of eosinophilic esophagitis. Despite severe clinical presentation, the HSV1 infection was self-limited. After a directed elimination diet was introduced, the clinical course was favorable, without the need for antiviral therapy.

Evaluation of the efficacy of low-level light therapy using 1072 nm infrared light for the treatment of herpes simplex labialis.

BACKGROUND: Recent research has shown that low-level light therapy (LLLT) using 1072 nm infrared light is effective in reducing the duration of herpes simplex labialis (HSL) episodes and enhancing the healing process. METHODS: This was a prospective, randomized, placebo-controlled, clinical trial to evaluate the efficacy of a 1072 nm light-emitting diode device for the treatment of HSL. In total, 87 patients with recurrent HSL were recruited and randomly divided into two groups. Subjects received a 3-min treatment with either 1072 nm infrared light therapy or placebo (sham) light therapy three times/day for 2 days. The devices used for both groups were identical in appearance and could not be differentiated by volunteers or researchers, and 1072 nm light is invisible to the human eye. The primary endpoint was healing time, which was taken as the time for the HSL lesions to resolve fully and for the underlying skin to become completely re-epithelialized, and the secondary endpoint was lesion crusting. RESULTS: The median time to healing for the active group was 129 h, compared with 177 h for the control group, which was significant (P = 0.01). There was no difference between the two groups for median time to lesion crusting (P = 0.66). CONCLUSIONS: Compared with placebo treatment, the treatment of HSL lesions with 1072 nm infrared light significantly reduced healing time.

Depletion of Langerhans cells in the tongue from patients with advanced-stage acquired immune deficiency syndrome: relation to opportunistic infections.

AIMS: To quantify and compare the expression of Langerhans cells (LCs) in the tongue mucosa of AIDS patients with different opportunistic infections, and from acquired immune deficiency syndrome (AIDS) and non-AIDS patients with normal tongues, using autopsy material. METHODS AND RESULTS: Human leucocyte antigen D-related (HLA-DR), CD1a and CD83 antibodies were used to identify and quantify LCs by immunohistochemistry in tongue tissue of 40 AIDS patients (10 with lingual candidiasis, 10 with lingual herpes, 10 with oral hairy leukoplakia and 10 with no lesions) and 23 tongues from human immunodeficiency virus (HIV)-negative control patients. Quantification was performed by means of conventional morphometry in four different regions (anterior, middle, posterior and lateral) of the tongue. The results were expressed as positive cells per area of epithelium. The AIDS patients presented a lower density of CD1a(+) cells (P < 0.001), HLA-DR (P < 0.003) and CD83 (P < 0.001) in all regions of the tongue compared to the non-AIDS control group. However, no differences in any of the markers were found when AIDS patients with different opportunistic infections were compared with AIDS patients without tongue infection. CONCLUSIONS: Advanced stage AIDS patients showed a depletion of LCs in the tongue mucosa. HIV infection induces cytopathic changes in LCs, contributing to their depletion regardless of the presence of oral infections.

The impact of HSV for inflammatory arthropathy patients.

Herpes simplex virus type 1 (HSV-1), also known as herpes labialis, is the etiologic agent of vesicular lesions of the oral mucosa commonly referred to as "cold sores". HSV-1 can also cause clinical disease in a wide variety of other anatomic locations including the genitalia, liver, lung, eye, and central nervous system. These infections can be severe, particularly in the setting of immunosuppression, such as inflammatory arthropathy patients on Methotrexate ± biological therapies. Here, we highlight the importance of physician awareness of HSV due to its potential impact for rheumatology patients.

Complicaciones estomatológicas en pacientes VIH positivos: correlaciones clínico demográficas y de laboratorio / Dental complications in HIV positive patients: clinical correlations demographic and laboratory

Las complicaciones estomatológicas (CE) en pacientes VIH+ muchas veces constituyen los primeros signos clínicos de la enfermedad, pudiendo funcionar como señalizadores del curso y progresión de la infección por el VIH y el SIDA. Este estudio evaluó la prevalencia de lesiones orales en pacientes VIH+ del Hospital de Enfermedades Infectocontagiosas Gizelda Trigueiro, en Natal-RN, Brasil y correlacionarlas con factores socio-demográficos como el sexo, edad, forma de contagio y status inmunológico. De acuerdo con los criterios de la EC-CLEARINGHOUSE/WHO, a través de examen clínico oral y conteo de células T CD4+ fueron evaluados 121 pacientes VIH+. Las lesiones más frecuentes fueron candidiasis (45.2%), leucoplasia vellosa (16.1%), eritema gingival linear (16.1%), herpes labial (12.9%), periodontitis necrosante (6.5%) y gingivitis necrosante (3.2%), ocurriendo con mayor frecuencia en hombres entre las edades de 30 a 44 años, que adquirieron el VIH a través de contacto sexual. Basado en los resultados de este estudio concluyese que hubo una prevalencia del perfil de complicaciones estomatológicas comúnmente relatado en la literatura. Las lesiones estuvieron asociadas a la reducción del número de células TCD4+, representando, por lo tanto marcadores de la progresión de la infección por el virus y/o de falla de la HAART, siendo así, un exhaustivo examen oral es importante en la evaluación clínica y acompañamiento de pacientes con VIH.

The stomatologic complications due to VIH infection are, a lot of times, the first clinical signs of the disease. These injuries may also function as beepers and sentries of the curse and progression of the VIH infection and SIDA. The objective of this work was to evaluate the prevalence of the oral injuries in VIH positive patients from the Hospital of Infected contagious Gizelda Trigueiro in Natal-RN, Brazil, and correlate them with demographic factors such as gender, age, form of VIH infection and immune status (T CD4+ cells). According to the criteria of EC-CLEARINGHOUSE/WHO, through clinical oral examination and T CD4+ cell count 121 patients were evaluated. The oral candidiasis was the most common lesion (45.2%), followed by oral hairy leukoplakia (16.1%), linear gingival erythema (16.1%), lips herpes (12.9%), necrotizing periodontitis (6.5%) and necrotizing gingivitis (3.2%), occurring predominantly in men between the ages 30 to 44 years, who acquired VIH infection through sexual contact. Based on the results of this study, concluded that there was a prevalence of the stomatologic complications profile that is commonly reported in the literature. These changes were associated with a decrease in the number of CD4+ T cells, representing markers of the infection progression and / or failure of HAART, so a thorough oral examination is important in clinical evaluation and follow up of patients with VIH.

Early treatment of cold sores with topical ME-609 decreases the frequency of ulcerative lesions: a randomized, double-blind, placebo-controlled, patient-initiated clinical trial.

BACKGROUND: Prior pilot studies support the use of antiviral medications with topical corticosteroids for herpes simplex labialis (HSL). ME-609 (Xerese, Xerclear) is a combination of 5% acyclovir and 1% hydrocortisone developed for the topical treatment of HSL. OBJECTIVES: The primary study end point was the prevention of ulcerative HSL lesions. METHODS: In all, 2437 patients with a history of HSL were randomized to self-initiate treatment with ME-609, 5% acyclovir in ME-609 vehicle, or ME-609 vehicle (placebo) at the earliest sign of a cold sore recurrence. Cream was applied 5 times/d for 5 days. A total of 1443 patients experienced a recurrence and initiated treatment with ME-609 (n = 601), acyclovir (n = 610), or placebo (n = 232). RESULTS: Of patients receiving ME-609, 42% did not develop an ulcerative lesion compared with 35% of patients receiving acyclovir in ME-609 vehicle (P = .014) and 26% of patients receiving placebo (P < .0001). In patients with ulcerative lesions, healing times were reduced in the ME-609 and acyclovir groups compared with placebo (P < .01 for both). The cumulative lesion area for all lesions was reduced 50% in patients receiving ME-609 compared with the placebo group (P < .0001). There were no differences among groups in the number of patients with positive herpes simplex virus cultures. The side-effect profile was similar among treatments. LIMITATIONS: The study did not contain a group treated with a topical corticosteroid alone. CONCLUSIONS: ME-609 prevented progression of cold sores to ulcerative lesions and significantly reduced the cumulative lesion area compared with acyclovir and placebo. ME-609 treatment offers additional therapeutic benefit compared with therapy with topical acyclovir alone.

Ceruloplasmin plasma levels in patients with severe forms of herpes infection.

BACKGROUND: Research interest in ceruloplasmin (CP) has significantly increased in recent years owing to new discoveries of its properties including anti-inflammatory and anti-oxidant effects. Data on CP blood plasma level in patients with herpetic infection caused by herpes simplex virus are scarce and often contradictory. Most point to a reduction of CP in the blood plasma of patients during the exacerbation of the disease with gradually return to normal values after treatment. There is evidence of an increase in CP levels during the acute period of CRHI (chronic recurrent herpes infection) and decrease in remission. MATERIALS AND METHODS: The content of ceruloplasmin in blood plasma was determined by immunoturbidimetry using the test-systems "Spinreact" (Spain) and biochemical analyzer "Architect C8000". RESULTS: We found that in patients with severe forms of chronic recurrent herpes infection in the exacerbation period, CP levels were increased by approximately 35% relative to the control values. However in the remission period in 80% of patients, CP concentrations remained elevated and in some patients the CP level was even increased in comparison with values in the exacerbation. Such dynamics of CP were not caused by the exacerbation of concomitant diseases. CONCLUSION: The increased CP levels in the remission period in patients with severe forms of chronic recurrent herpes infection may have been caused by its effect as an endogenous antioxidant. No correlations of CP levels with other laboratory signs of acute inflammation were found but identified was a relation to free radical activity.
