ABSTRACT

El sarcoma de Kaposi se ha convertido en uno de los tumores más prevalentes en África tras la epidemia de VIH, que afecta de una manera similar a hombres y mujeres. El retraso diagnóstico y el limitado acceso a tratamiento antirretroviral o quimioterapia condicionan el pronóstico de los pacientes que lo padecen. En este artículo se realiza una revisión sobre la referida enfermedad, con el objetivo de describir sus aspectos más relevantes en los últimos años en África, como son su epidemiología, caractéristicas clínicas y opciones terapéuticas existentes. Este tumor es provocado por la infección por virus herpes humano tipo 8, que resulta más prevalente en las zonas rurales del continente africano. Se postula la transmisión a través de la saliva como la vía más importante de contagio en África. La inmunodepresión que causa el VIH favorece el efecto oncogénico del virus. La forma epidémica de SK se manifiesta inicialmente como lesiones hiperpigmentadas o violáceas en la piel, que pueden extenderse a linfáticos o mucosas y a nivel sistémico, principalmente a pulmón o aparato digestivo. El síndrome de reconstitución inmune sistémica puede complicar la evolución del paciente. El inicio temprano de la terapia antirretroviral resulta imprescindible. Además, el pronóstico de los pacientes mejora con la suma de tratamiento quimioterápico con doxorrubicina, vincristina, etopóxido o bleomicina principalmente(AU)


Kaposi sarcoma (KS) has become one of the most prevalent tumors in Africa after the HIV epidemic. KS affects both men and women. Diagnostic delay and limited access to antiretroviral treatment or chemotherapy have an impact on the prognosis of KS patients. A review was conducted about KS with the purpose of describing its most outstanding characteristics in recent years in Africa, such as its epidemiology, clinical features, and existing therapeutic options. This tumor is caused by infection with human herpesvirus 8, which is more prevalent in rural areas of the African continent. Transmission via saliva was found to be the most important transmission route in Africa. HIV-related immunosuppression fosters the oncogenic effect of the virus. The epidemic form of KS initially presents as hyperpigmented or violet-colored skin lesions which may extend to lymph nodes or mucosae, or systemically, mainly to the lungs or the digestive tract. Systemic immune reconstitution syndrome may complicate the patient's evolution. Early start of antiretroviral therapy is indispensable. Additionally, prognosis improves with chemotherapy with doxorubicin, vincristine, etoposide or bleomycin, mainly(AU)

ABSTRACT

ABSTRACT Kaposi's sarcoma (KS) is an endothelial neoplasia caused by infection with the human herpesvirus 8 (HHV-8), and the type associated with the human immunodeficiency virus (HIV) is considered the most aggressive and frequent. This paper reports a case of mucocutaneous KS in a patient not formerly aware of being an HIV bearer. A 38-year-old male patient has sought treatment with multiple oral lesions and one in the skin. Serology was positive for HIV and incisional biopsy diagnosed KS. After 11 months of chemotherapy and antiretroviral therapy, there was complete remission of the skin KS and partial remission of oral lesions.


RESUMO Sarcoma de Kaposi (SK) é uma neoplasia endotelial causada pelo herpes vírus humano tipo 8 (HHV-8), e o tipo associado ao vírus da imunodeficiência humana (HIV) é considerado o mais agressivo e frequente. Relata-se um caso de SK mucocutâneo em indivíduo não anteriormente ciente de ser portador de HIV. Paciente do sexo masculino, 38 anos, procurou atendimento com queixa de múltiplas lesões orais e uma lesão em pele. A sorologia foi positiva para HIV, e a biópsia incisional das lesões teve como diagnóstico SK. Após 11 meses de terapia antirretroviral e quimioterapia, houve remissão completa do SK cutâneo e parcial das lesões orais.

ABSTRACT

FUNDAMENTOS - O DNA viral pode atuar como oncogene, favorecendo o desenvolvimento de neoplasias, como as linfoides e da pele. Entre esses vírus, encontram-se alguns herpes-vírus humanos. OBJETIVO - Identificar a presença de DNA do herpes-vírus humano tipo 1 em neoplasias epiteliais pré-malignas,malignas e pele normal de indivíduos controle, avaliando seu papel na carcinogênese. MÉTODOS - Identificação, por reação em cadeia da polimerase, do DNA viral do tumor e pele sã de 41 pacientes e comparação com grupo controle, sem neoplasia. Análise estatística: Testes de Fisher e de McNemar. RESULTADOS - O vírus foi identificado em 20 indivíduos sem e em 21 com neoplasia. Destes últimos, 11 o expessaram apenas nas células tumorais. A diferença, entretanto, não foi estatisticamente significante. CONCLUSÕES - Parece não haver relação direta entre o encontro do DNA viral na pele sã e na pele tumoral. Sua presença pode facilitar o desenvolvimento da neoplasia ou apenas coincidir de se localizar onde esta já ocorreu.


BACKGROUND - Viral DNA may act as an oncogene, especially in skin and lymphoid organs. This group includes some human herpes virus. OBJECTIVE - To identify human herpes virus type 1 DNA in pre-malignant and malignant skin samples of epithelial tumors comparing to normal skin to determine its role in carcinogenesis. METHODS - Forty-one patients with epithelial tumors were submitted to biopsies from tumor and normal skin. The control group comprised 41 biopsies from patients with other dermatoses than cancer. After DNA extraction, polymerase chain reaction was performed to identify 199-bp band. The results were statistically evaluated by Fisher and McNemar tests. RESULTS - The virus was identified in 20 subjects without cancer and in 21 with skin cancer. From these, 11 expressed it only in tumor cells. This difference was not significant. CONCLUSION - There seem to be no direct relation between viral findings in normal skin and skin cancer cells. It may act as a promoter or just coexist at the same site where a neoplastic transformation has already occurred.

ABSTRACT

Se evaluó la actividad antiviral del extracto acuoso de Phyllanthus orbicularis; un miembro de la familia Euohorbiacea, frente al virus del herpes simple tipo 1 (VHS-1), tanto en cultivo celular, específicamente en fibroblastos de prepucio humano, como un modelo animal en ratones Balb-c. El efecto extracelular del extracto sobre VHS-1, resultó ser efectivo, obteniéndose un índice selectivo de 44, lo que apunta hacia una posible acción virucida sobre la partícula. En el ensayo in vivo, la administración del extracto acuoso (12 mg/kg), de manera tópica, redujo de forma significativa el desarrollo de lesiones en ratones infectados por vía subcutánea con VHS-1 (1 x 106 UFP). Estos resultados sugieren la consideración de Phyllanthus orbicularis, como un posible candidato anti VHS-1.


The antiviral activity of the aqueous extract of Phyllanthus orbicularis, a member of the Euohorbiacea family, against the simple herpes virus type1 was evaluated in cellular culture, specifically in fibroblasts of human prepucium, and in an animal model, Balb-c mice. The extracelullar effect of the extract on HIV-1 proved to be effective. A selective index of 44 was obtained, which shows a possible virucidal action on the particle. In the trial in vivo, the topical administration of the aqueous extract (12 mg/kg) reduced significantly the development of lesions in mice subcutaneously infected with HIV-1 (1 x 106 UFP). These results suggest the consideration of Phyllanthus orbicularis as a possible anti-HIV-1 candidate.
