ABSTRACT

Herpes simplex virus type 1 (HSV-1) is primarily responsible for the development of painful mucocutaneous viral lesions in the head and neck region. Antimicrobial photodynamic therapy (aPDT) consists of the use of a photosensitizing chemical substance, which interacts with an appropriate light source under the presence of oxygen, with consequent destruction or microorganisms' inactivation . The aim of this study was to conduct a literature review on the use of aPDT in the treatment of HSV-1, as well as to identify and characterize the main photosensitizing agents used in this technique. This was a narrative literature review, based on the research of scientific articles carried out in the PubMed database, from February to June 2021, using the crossing of the descriptors Decs/Mesh "photodynamic therapy" and "viral infection"; "photodynamic therapy" and "herpes virus". According to the established criteria, a total of 27 articles published in the last 20 years were included. The results demonstrate that despite the scarcity of studies involving aPDT in herpetic lesions, a single application of this therapy and with different protocols improved the clinical appearance and associated symptoms. Thus, antiviral PDT has been shown to be effective in in vitro and in vivo studies, regardless of the dye used. However, more controlled clinical trials need to be carried out in order to establish the real effectiveness of this therapeutic resource in viral infections. (AU)


O vírus herpes simples tipo 1 (HSV-1) é o principal responsável pelo desenvolvimento de lesões virais dolorosas mucocutâneas em região de cabeça e pescoço. A terapia fotodinâmica antimicrobiana (aPDT), por sua vez, consiste no uso de uma substância química fotossensibilizadora, que interage com uma fonte de luz apropriada sob a presença de oxigênio, com consequente destruição ou inativação de microrganismos. O objetivo do presente trabalho foi realizar uma revisão de literatura sobre o uso da aPDT no tratamento de HSV-1, bem como identificar e caracterizar os principais agentes fotossensibilizadores utilizados nessa técnica. Tratou-se de revisão narrativa de literatura, com base na pesquisa de artigos científicos realizada na base de dados PubMed, de fevereiro a junho de 2021, utilizando o cruzamento dos descritores Decs/Mesh "photodinamic therapy" and "viral infection"; "photodynamic therapy" and "herpes virus". De acordo com os critérios estabelecidos, um total de 27 artigos publicados nos últimos 20 anos foram incluídos. Os resultados demonstram que apesar da escassez de estudos que envolvam a aPDT em lesões herpéticas, uma única aplicação desta terapia e com diferentes protocolos promoveu melhora do aspecto clínico e dos sintomas associados. Desta maneira, a PDT antiviral demonstrou ser efetiva em estudos in vitro e in vivo, independente do corante adotado. Entretanto, mais ensaios clínicos controlados precisam ser realizados com o objetivo de se estabelecer a real eficácia deste recurso terapêutico em infecções virais. (AU)

ABSTRACT

Introdução: A lisina é um dos aminoácidos essenciais, cuja ação na profilaxia do herpes simples recorrente orolabial tem sido demonstrada em estudos científicos. Procedimentos de resurfacing facial com laser e outras tecnologias podem reativar quadros de herpes simples. Objetivo: Avaliar a incidência de casos de herpes orolabial em pacientes submetidos a tratamentos com lasers fracionados, ablativo e não ablativo, e microagulhamento robótico, em uso profilático de L-lisina. Métodos: Selecionada amostra de 100 pacientes a ser submetidos a profilaxia para herpes simples com L-lisina, todos reavaliados sete dias após a sessão de laser. Caso fosse verificada infecção herpética, doses de antivirais orais equivalentes às utilizadas para o tratamento do herpes-zóster seriam prescritas, conforme orienta a literatura. Resultados: Apenas 2% da amostra apresentou herpes simples após o procedimento com o uso da profilaxia com L-lisina; ambos os pacientes realizaram sessões de laser fracionado ablativo e apresentavam história prévia de infecção pelo herpes simples. Conclusões: Além do baixo custo, a L-lisina é produto natural que se mostrou seguro e eficaz na profilaxia do herpes simples em procedimentos de resurfacing, apresentando taxa de reativação viral similar ou inferior às obtidas com o uso de antivirais.


Introduction: Lysine is one of the essential amino acids, with a role in the prophylaxis of recurrent orolabial herpes simplex that has been demonstrated in scientific studies. Facial resurfacing procedures with laser and other technologies can reactive herpes simplex. Objective: To evaluate the incidence of cases of orolabial herpes in patients submitted to treatments with fractional ablative and non-ablative lasers and robotic microneedling, under prophylactic l-lysine. Methods: A sample of 100 was selected to have prophylactic l-lysine for herpes simplex. A re- -evaluation of all patients was conducted seven days after laser treatment. If herpes infection was detected, doses of oral antiviral similar to those used for herpes-zoster treatment would be prescribed, guided by the literature. Results: Only 2% of the sample demonstrated herpes simplex after the procedure with prophylactic l-lysine. Both patients underwent ablative fractional laser treatment and had past history of herpes simplex infection. Conclusions: Besides the low cost, l-lysine is a natural product that proved to be safe and effective for the prophylaxis of herpes simplex in resurfacing procedures, with a similar or lower rate of viral activation to the use of antivirals.

ABSTRACT

ABSTRACT Several treatments for recurrent herpes labialis have been tested, including intradermal snake venom, camphor compresses, psychiatric treatments, vitamin C and other vitamin complexes. Nowadays, topical and systemic retroviral drugs such as acyclovir, valacyclovir and vadarabina are the drugs of choice. However they are only effective for symptoms minimization of existing lesions, without eliminating the virus permanently. In this study an alternative treatment with oral L-lysine is presented. This is one of the eight essential not manmade amino acids which should be acquired through feeding since they are important for protein synthesis and organism development. It was observed a significant effect on the annual incidence reduction of recurrent herpes in 12 patients with 8-year follow up.


RESUMO Vários tratamentos para herpes labial recorrente foram testados, incluindo veneno de cobra intradérmica, compressas de cânfora, tratamentos psiquiátricos, vitamina C e outros complexos vitamínicos. Atualmente, as drogas retrovirais tópicas e sistêmicas, como o aciclovir, o valaciclovir e a vadarabina são as drogas de escolha. No entanto, eles são eficazes apenas para minimizar os sintomas das lesões existentes, sem eliminar o vírus permanentemente. Neste estudo é apresentado um tratamento alternativo com L-lisina oral. Este é um dos oito aminoácidos essenciais não fabricados pelo homem, que devem ser adquiridos através da alimentação, uma vez que são importantes para a síntese de proteínas e o desenvolvimento do organismo. Foi observado um efeito significativo na redução da incidência anual de herpes recorrente em 12 pacientes com 8 anos de seguimento.

ABSTRACT

Um dos grandes desafios do Cirurgião-Dentista é o controle microbiológico nas patologias dentárias. Independentemente da especialidade, a redução microbiana para o sucesso do tratamento é necessária. A terapia fotodinâmica vem sendo utilizada como coadjuvante ao tratamento tradicional, reduzindo significativamente a quantidade de microrganismos nos sítios-alvo e contribuindo para a solução de casos, principalmente na presença de infecções resistentes. Esta revisão de literatura tem como objetivo apresentar estudos laboratoriais e clínicos relacionados à terapia fotodinâmica em Periodontia, Endodontia e Estomatologia. Apesar da variedade de protocolos utilizados nas recentes pesquisas, a terapia fotodinâmica mostra-se promissora como coadjuvante ao tratamento convencional. Além disso, apresenta grande utilidade, fácil acessibilidade e baixo custo para o Cirurgião-Dentista frente a processos infecciosos em Odontologia.


One of the great challenges of the dentist is the microbiological control in dental pathologies. Regardless of specialty, microbial reduction for successful treatment is necessary. Photodynamic therapy has been used as an adjunct to traditional treatment, significantly reducing the amount of microorganisms in the target sites and contributing to the solution of cases, especially in the presence of resistant infections. This literature review aims to present laboratory and clinical studies related to photodynamic therapy in Periodontics, endodontics and Stomatology. Despite the variety of protocols used in recent research, photodynamic therapy is potentially used as an adjunct to conventional treatment. In addition, it is useful, easy to apply and with low cost to the dentist.

ABSTRACT

Os herpes vírus humanos (HHV) fazem parte de uma família -Herpesviridae- e têm como seu hospedeiro, unicamente, o homem. São ubíquos e latentes e, uma vez ocorrida a primo-infeção, permanecem no organismo do indíviduo afetado durante toda a sua vida. O presente trabalho se constitui em uma revisão de literatura com o objetivo de abordar os tipos de HHV e seus tratamentos, com ênfase nas manifestações orais. Os HSV 1 e 2 estão geralmente associados à Gengivoestomatite Herpética Primária, Herpes Labial Recorrente e Herpes Intraoral Recorrente. O HHV-3 provoca a Varicela e, por reinfecção, pode ser a causa do surgimento do Herpes-zóster. O HHV- 4 está diretamente ligado à Mononucleosa Infecciosa, ao Linfoma de Burkitt e ao Carcinoma Nasofaríngeo. O HHV-5 pode levar a má-formações congênitas. O HHV-6 provoca o exantema súbito e está associado à esclerose múltipla, o que demonstra seu forte potencial neuro-invasivo. O HHV-7 correlaciona-se ao vírus da AIDS, uma vez que, para ambos, a molécula CD4 é essencial a fim de funcionar como receptor, e o HHV-8 está estreitamente ligado ao Sarcoma de Kaposi. Nenhuma das terapias usadas para o tratamento representa uma cura para a infecção do vírus, uma vez que elas atuam apenas na sua fase ativa. O conhecimento dos tipos virais, das suas características clínicas e manifestações orais são de suma importância para o correto diagnóstico da doença, para a obtenção de sucesso no tratamento e, consequentemente, para a manutenção da saúde populacional.


The human herpes viruses (HHV) take part of a virus family - Herpesviridae- and these viruses have human as only host. They are ubiquitous and latents, and once the primary infection has occurred, they stay within the host's organism for their entire life. This paper is a review about the human herpes viruses types, their treatments and emphasizes their oral manifestations. The HSV 1 and 2 are usually associated to Primary Herpetic Gingivostomatitis, Recurrent Labial Herpes and Reccurent Intra-Oral Herpes. The HHV-3 causes Varicella, mainly in children, and, by reinfection, can be the cause of the appearance of Herpes-zoster. The HHV-4 is directly linked to Infectious Mononucleosis, Burkitt Lymphoma and Nasopharyngeal Carcinoma. The HHV-5 can lead to congenital malformations. The HHV-6 causes sudden rash and is associated with multiple scleroszis, which shows its strong neuro-invasive potential. The HHV-7 is related to AIDS virus because, for both, the CD4 molecule is essential to act as receiver. The HHV-8 is closely linked to Kaposi's Sarcoma. None of the therapies used as treatment gives a cure to the viral infection, once the drugs only have their effect during the virus active phase. The knowledge of the types of herpes virus, its clinical characteristics and oral manifestations is of paramount importance for the correct diagnosis of the disease to obtain treatment success and, consequently, maintenance of population health.

ABSTRACT

Introducción: El Herpes Labial Recurrente supone una condición inmunológica alterada, tal como una hiperactividad de células T-reguladoras CD4+CD25+ (Treg). Éstas ejercen control sobre la tolerancia periférica y reducen el riesgo inmunopatológico, suprimiendo otras líneas celulares. Por ende, la supresión ejercida sobre la reacción inmune antiviral podría afectar negativamente el curso de la infección. Este contexto ha impulsado la búsqueda de nuevas alternativas inmunomoduladoras como la Equinácea purpúrea. Dada su propiedad inmunosupresora, se propone en el tratamiento del Herpes Labial Recurrente. Metodología: Estudio clínico prospectivo que analiza las subpoblaciones linfocitarias en 12 pacientes con Herpes Labial Recurrente, antes y después de recibir Equinácea purpúrea (30 gotas tres veces al día durante siete días).Resultados: En comparación con individuos sanos, los pacientes presentan una respuesta aumentada de células Treg. Esta condición se reduce significativamente tras recibir Equinácea purpúrea (515 + 145 y 432 + 113 cel/mm3 antes y después del tratamiento, respectivamente, p < 0,005). Conclusión: La hiperactividad de células Treg podría explicar el estado de inmunosupresión de estos pacientes y favorecería la persistencia viral. Se propone esta fitomedicina como una alternativa inmunoterapéutica beneficiosa.


Background: Recurrent Herpes Labialis patients may suffer from immunological alterations, such as CD4+CD25+Regulatory-T Cell (Treg) hyperactivity. These cells control peripheral tolerance and reduce immunopathology risk by suppressing other immunological cells. Hence, the Treg cell suppression on the antiviral immune reaction may perturb adversely the herpes infection outcome. This scenario has forced physicians to explore new immunomodulatory alternatives in Phytomedicine, such as Echinacea purpurea. Regarding the immunosuppressive property, it has been challenged to be employed in the Recurrent Herpes Labialis management. Methods: Clinical prospective study that analyzed lymphocytic subpopulation profile in twelve patients with Recurrent Herpes Labialis, before and after receiving E. purpurea (30 drops three times a day during seven days). Results: Comparing to healthy subjects, patients presented an enlarged Treg cell response. This condition became significantly reduced after receiving E. purpurea. (515 + 145 and 432 + 113 cel, before and after treatment respectively, p < 0.005). Conclusion: The intensified Treg cell activity may elucidate the immune suppression these patients undergo, aiding the viral persistence and survival. This proposes E. purpurea asa beneficial immunotherapeutic alternative.

ABSTRACT

Gengivoestomatite Herpética Aguda (GEHA) representa uma doença infecto-contagiosa causada pelo vírus herpes simples. Revela relevante freqüência entre as crianças de zero a seis anos de idade, apresentando sintomatologia prodrômica e manifestação clínica autolimitada entre dez a quatorze dias. O conhecimento desta patologia por parte do cirurgião dentista é de fundamental importância, em decorrência do potencial de contaminação, morbidade e baixa no estado geral do paciente, somadas às possíveis complicações, observadas, sobretudo, em pacientes imunocomprometidos ou imunologicamente imaturos.


Acute Herpetic Gingivostomatitis (AHG) is an infect-contagious disease caused by a virus called Herpes simplex. This illness demonstrates important frequency among very young children (varying age from 0 to 6), presenting specific symptoms and auto-limited clinical manifestations during a period of ten to fourteen days. The knowledge of the referred pathology is of fundamental importance to the dentist, even more its contamination levels, morbidity and down general patient health condition plus the possible adversed progression of the AHC in immunocompromised or immunologic immature patients.

ABSTRACT

Se realizó un estudio descriptivo, longitudinal y prospectivo consistente en la descripción citológica y clínica de las muestras obtenidas en 150 pacientes con herpes labial diagnosticadas y atendidas en las diferentes consultas, que reunieron criterios de inclusión objetivos y subjetivos. Las muestras obtenidas por raspado de la superficie afectada se fijaron con cytospray y se colorearon con el método de Papanicolau; fueron leídas al inicio y a las 48 horas para evaluar la recuperación de la mucosa bajo los efectos del láser infrarrojo de arsenurio de galio y aluminio en dosis de 0,6 J/cm2 durante 1 minuto, para un total de 2 a 3 sesiones. Las células intermedias de las mucosas mostraron el mayor nivel de multiplicación, la recuperación fue identificada a partir de las 48 horas de evaluación citológica, clínicamente al 4to. día. Se recomienda evaluar la eficiencia del nuevo esquema terapéutico con láser para esta afección, así como su costo y efectividad.


A descriptive, longitudinal and prospective study consisting in the cytological and clinical description of the samples obtained in 150 patients with herpes labialis diagnosed and seen in different consultation rooms was conducted. Objective and subjective inclusion criteria were gathered. The samples of the affected surfaces obtained by curettage were fixed with cytospray and they were colored by using Papanicolau’s method. They were read at the beginning and 48 hours later to evaluate the recovery of the mucosa under the effects of the infrared laser of gallium and alluminum arsenide at doses of 0.6 J/cm3 during a minute for a total of 2 or 3 sessions. The intermediate cells of the mucosas showed the highest level of multiplication. The recovery was identified 48 hours after the cytologic evaluation and from the clinical point of view on the 4th day. It was recommended to evaluate the efficiency of the new therapeutic scheme with laser to treat this affection, as well as its cost and effectiveness.
