Abstract INTRODUCTION: Apart from masking the diagnosis of AIDS in patients with HIV/AIDS, human T-cell lymphotropic virus (HTLV), when present, also increases the risk of myelopathies and neurological disease in these patients. METHODS: Disease prevalence was estimated by ELISA and confirmed by Western blot. RESULTS: The coinfection rate was 1.5% (11/720); 10 of 11 patients had HTLV-1, and the remaining one had HTLV-2. The majority were male, over 40 years old, and of pardo color (ethnicity). CONCLUSIONS: There was no association between the risk factors examined and HTLV/HIV coinfection. This is the first study to report the occurrence of HTLV-2 in Pernambuco.

Faringotonsilite causada por Streptococcus β-hemolítico afeta principalmente crianças e imunocomprometidos, sendo Streptococcus pyogenes (Grupo A) o agente mais comum em faringotonsilites bacterianas. OBJETIVO: Este trabalho objetivou a busca por Streptococcus β-hemolítico do Grupo A (SBHGA) e Não A (SBHGNA) na orofaringe de indivíduos com necessidades especiais da APAE (Maceió-AL). MÉTODO:Estudo prospectivo com amostras da orofaringe de pacientes com síndrome de Down e outras desordens mentais (teste) e estudantes de escola privada (controle) de 5-15 anos. Culturas em ágar sangue (5%) foram identificadas através dos testes de Gram/catalase e o método de disco difusão com bacitracina/sulfametoxazol-trimetoprim, aplicando-se o teste Chi-quadrado em análises estatísticas. RESULTADOS: Um total de 222 colônias bacterianas foram isoladas em 74 indivíduos da APAE e 65 no grupo controle. No grupo teste, episódios prévios de faringotonsilites foram relatados por 36,49% (27/74) e 9,46% (7/74) foram diagnosticados com sintomas e/ou sinais sugestivos de infecção orofaríngea. Nenhuma amostra de S. pyogenes foi confirmada na APAE, sendo todas identificadas como SBHGNA, com cinco SBHGA no grupo controle. CONCLUSÃO:A identificação precoce de Streptococcus β-hemolítico é importante para o tratamento rápido de faringotonsilites e a ausência de S. pyogenes evita futuras sequelas supurativas ou não supurativas no grupo da APAE.

Pharyngotonsillitis by β-hemolytic Streptococcus mostly affects children and imunocompromissed, being Streptococcuspyogenes (Group A) the most common agent in bacterial pharyngotonsillitis. AIM:This work targeted the research of β-hemolytic Streptococcus Group-A (SBHGA) and No-A (SBHGNA) in the oropharynx of individuals with special health needs from the APAE (Maceió-AL). METHOD: A prospective study with oropharynx samples from patients with Down syndrome and other mental disorders (test) and students from a private school (control) aged 5-15 years. Cultures in blood agar (5%) were identified through Gram/catalase tests and bacitracin/trimethoprim-sulfamethoxazole disk diffusion method, applying the chi-squared statistical analysis. RESULTS: A total of 222 bacterial colonies were isolated in 74 individuals from APAE and 65 in the control group. In the test group, previous episodes of pharyngotonsillitis were reported by 36.49% (27/74) and 9.46% (7/74) were diagnosed with symptoms and/or signs suggestive of oropharynx infection. No positive sample of S. pyogenes was confirmed at APAE, being all samples classified as SBHGNA, with 5 SBHGA in the control group. CONCLUSION: The early identification of β-hemolytic Steptococcus is important for the fast treatment of pharyngotonsillitis and the absence of S. pyogenes avoid future suppurative or not-suppurative sequels in the group from APAE.
