ABSTRACT

Viral coinfection in the oral cavity associated to HIV infection was evaluated in 180 children from birth to 13 years of age of both sexes. The oral examinations were performed at the Pediatric AIDS Outpatient Clinic, São Lucas Hospital and Clinic Hospital, both in Porto Alegre, Brazil and at the School of Dental Medicine, University Hospital Center, State University of New York at Stony Brook, USA. The aim of this study was to identify the presence of viral infections in the oral cavity. PCR technique was used to determine opportunistic viral infections caused by CMV, EBV, and HSV in mucosal swabs. A high frequency of viral infection was detected in the oral cavity of HIV-infected children determined by the PCR technique. HIV-infected children with viruses had a favorable CD4+ T lymphocyte count and unfavorable viral load.

ABSTRACT

A relação entre a infecção pelo HIV e a presença de diferentes tipos de vírus na cavidade bucal foi estudada em 180 crianças HIV-positivo, com idades entre zero e 13 anos de idade, de ambos os sexos. Os exames foram realizados nos Ambulatórios de Aids Pediátrica dos Hospitais São Lucas e de Clínicas, ambos em Porto Alegre, RS, Brasil e no Centro Hospitalar Universitário da Universidade Estadual de Nova Iorque, em Stony Brook (EUA). O objetivo desta pesquisa foi usar a técnica da PCR para detectar a presença dos vírus CMV, EBV e HSV na cavidade bucal desses pacientes, independentemente da presença ou não de manifestações estomatológicas relacionadas aos mesmos. Pode-se concluir que foi alta a freqüência de vírus detectados na cavidade bucal das crianças da amostra através da técnica da PCR e que a contagem média de linfócitos T-CD4+ das crianças com a presença dos vírus encontrava-se próxima da normalidade, enquanto a Carga Viral do HIV encontrava-se elevada.

ABSTRACT

A hipoplasia do esmalte é uma alteração do esmalte dental, decorrente da ação de diferentes fatores etiológicos durante o período de formação desse. Dentre os possíveis fatores etiológicos, merecem destaque as alterações sistêmicas presentes em crianças infectadas pelo HIV. O objetivo deste trabalho foi estudar a freqüência da hipoplasia do esmalte em crianças infectadas pelo HIV e a provável relação desta patologia dental com a classificação da AIDS pediátrica. A amostra foi composta por 156 crianças brasileiras e 42 crianças norte-americanas, de zero a treze anos de idade, infectadas pelo HIV. A metodologia incluiu o preechimento de uma ficha individual, o exame clínico odontológico buscando a presença de dentes com anomalia dental do tipo hipoplasia do esmalte e a revisão dos prontuários médicos das crianças. Na amostra estudada, 24 crianças (12,12%) apresentaram hipoplasia do esmalte, sendo 17 brasileiras e 7 norte-americanas. A freqüência de crianças com hipoplasia do esmalte na amostra estudada foi considerada baixa. A distribuição das 24 crianças com hipoplasia do esmalte, de acordo com a classificação da AIDS pediátrica foi: 12 (50%) na categoria clínica C, 8 (33,33%) na categoria B e 4 (16,67%) na categoria A. A maioria das crianças com hipoplasia do esmalte encontrava-se na categoria C da AIDS pediátrica, considerada a mais grave.

ABSTRACT

OBJECTIVES: This study had two objectives: (1) to investigate the socioeconomic and cultural characteristics of HIV-infected children and their families in relation to the presence of oral manifestations of AIDS and (2) to identify the most frequent oral manifestations of AIDS in the sample of children studied. METHODS: The sample consisted of a total of 184 children - both boys and girls - from 0 to 13 years old. The children were receiving care at two hospitals in the city of Porto Alegre, Brazil (the Hospital de Clínicas de Porto Alegre and the Hospital São Lucas da Pontifícia Universidade Católica), and at Stony Brook University Hospital, which is in the state of New York, United States. Data were analyzed using the chisquare test, Student's t test, and analysis of variance. RESULTS: Of the 184 patients, 117 of them (63.59%) were receiving care at the Hospital de Clínicas de Porto Alegre, 26 (14.13%) at the Hospital São Lucas, and 41 (22.28%) at Stony Brook University Hospital. In the Brazilian sample (the two hospitals in Porto Alegre) 42.66% of the children were living with their natural parents (mostly with the mother), while in the United States 56.10% of the children were living with foster families. Concerning income, 39.86% of the Brazilian families had a monthly income ranging from US$ 180 to US$ 450, and 33.57% had no income or did not provide information. With the United States sample, we were not allowed to ask about income, but all the families were classified by the social workers as having a monthly income below US$ 1 000. HIV was acquired through vertical transmission by 97.20% of the Brazilian children and by 97.56% of the children in the United States sample. Oral manifestations were more frequent in the Brazilian children (72.73%) than in the children in the United States sample (53.66%) (P = 0.01). CONCLUSIONS: The frequency of oral manifestations in the samples in both Brazil and the United States was influenced by socioeconomic and cultural conditions, family structure and income, access to information concerning AIDS, and adherence to treatment.

ABSTRACT

OBJETIVO: Investigar as características socioeconômicas e culturais de crianças infectadas pelo HIV e de suas famílias, relacionando-as com a presença de manifestaçöes estomatológicas da AIDS, e identificar as manifestaçöes estomatológicas mais freqüentes na amostra estudada. MÉTODO: A amostra foi composta por 184 crianças de ambos os sexos, com idade entre 0 e 13 anos, atendidas no Hospital de Clínicas de Porto Alegre e Hospital Säo Lucas da Pontifícia Universidade Católica, em Porto Alegre, Brasil, e no hospital universitário da Universidade do Estado de Nova Iorque em Stony Brook, Estado de Nova Iorque, Estados Unidos. Os dados foram analisados pelos testes do qui-quadrado, t de Student e análise de variância. RESULTADOS: Dos 184 pacientes, 63,59 por cento eram do Hospital de Clínicas de Porto Alegre; 22,28 por cento do hospital de Stony Brook; e 14,13 por cento do Hospital Säo Lucas. Na amostra brasileira, 42,66 por cento das crianças residiam com os pais naturais (principalmente com a mäe), enquanto que nos Estados Unidos 56,10 por cento das crianças moravam com pais adotivos. Em relaçäo à renda, 39,86 por cento das famílias no Brasil ganhavam entre 180 e 450 dólares mensais; 33,57 por cento näo tinham renda ou näo forneceram seus dados. Nos Estados Unidos, a pergunta sobre renda näo foi autorizada, mas todas as famílias foram classificadas pelos assistentes sociais do hospital como tendo renda abaixo de 1 000 dólares. O HIV foi adquirido por transmissäo vertical em 97,20 por cento dos casos no Brasil e 97,56 por cento nos Estados Unidos. A freqüência das manifestaçöes estomatológicas foi maior nas crianças brasileiras (72,73 por cento) do que nas norte-americanas (53,66 por cento) (P = 0,01). CONCLUSÖES: As condiçöes socioeconômicas e culturais, estrutura e renda familiar, acesso a informaçäo sobre AIDS e a adesäo aos esquemas terapêuticos influenciaram a freqüência das manifestaçöes estomatológicas nas duas amostras.
