Resumo: | INTRODUCTION. Regulatory T lymphocytes (TReg) are cells specialized in suppressing super-reactive immune responses as in HIV infection. OBJECTIVES. To verify the absolute concentration of TReg lymphocytes during the course of HIV infection in patients being diagnosed or already undergoing treatment. MATERIALS AND METHODS. Study carried out with 50 individuals who spontaneously sought a private laboratory in Belém - Pará to perform tests to quantify CD4+ and CD8+ T lymphocytes and viral load (Groups 2 and 3) or only blood count (Group 1 - control), in the period of July from 2018 to August 2019. Group 2 consisted of people who had detectable RT-PCR for HIV1/HIV2 at diagnosis; and Group 3 formed by people who had detectable RT-PCR for HIV1/HIV2 and were already on treatment. RESULTS. In Group 1, the median age was 56.5 years and there was a statistical dependence (p = 0.00451) between the absolute values of CD4+ T Lymphocytes and TReg Lymphocytes. In Group 2, the median age was 39.5 years and there was a statistical difference (p=0.00234) only when the viral load was undetectable and the absolute values of TReg lymphocytes were low. In Group 3, the median age was 40.5 years and there was statistical dependence (p = 0.00188) between the absolute values of CD4+ T Lymphocytes and TReg Lymphocytes. CONCLUSION. Our data reinforce the observation of other authors regarding the increase in absolute values of TReg lymphocytes in patients on specific antiretroviral therapy. |

Os linfócitos T regulatórios (TReg) são células especializadas na supressão de respostas imunes superreativas como na infecção pelo vírus HIV. OBJETIVOS. Verificar a concentração absoluta de linfócitos TReg durante o curso da infecção pelo HIV em pacientes em diagnóstico ou já em tratamento. MATERIAIS E MÉTODOS. Estudo realizado com 50 indivíduos que procuraram espontaneamente um laboratório particular de Belém - Pará para realizar exames de quantificação de linfócitos T CD4+ e T CD8+ e carga viral (Grupos 2 e 3) ou somente hemograma (Grupo 1 - controle), no período de julho de 2018 a agosto de 2019. O Grupo 2 foi formado por pessoas que tinham RT-PCR detectável para HIV1/HIV2 em diagnóstico; e Grupo 3 formado por pessoas que tinham RT-PCR detectável para HIV1/HIV2 e já estavam em tratamento. RESULTADOS. No Grupo 1 a mediana de idade foi de 56,5 anos e observou-se dependência estatística (p = 0,00451) entre os valores absolutos de Linfócitos T CD4+ e de Linfócitos TReg. No Grupo 2 a mediana de idade foi de 39,5 anos e houve diferença estatística (p=0,00234) apenas quando a carga viral estava não detectável e os valores absolutos de linfócito TReg estavam baixos. No Grupo 3 a mediana de idade foi de 40,5 anos e houve dependência estatística (p = 0,00188) entre os valores absolutos de Linfócitos T CD4+ e de Linfócitos TReg. CONCLUSÃO. Nossos dados reforçam a observação de outros autores quanto ao aumento dos valores absolutos de linfócitos TReg em pacientes em terapia antiretroviral específica.Universidade Municipal de São Caetano do Sul - USCS2024-01-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://seer.uscs.edu.br/index.php/revista_ciencias_saude/article/view/881710.13037/2359-4330.8817Journal of Health Care; Vol. 21 (2023): Revista de Atenção à Saúde - RAS; E20238817Revista de Atenção à Saúde; v. 21 (2023): Revista de Atenção à Saúde - RAS; E202388172359-433010.13037/ras.v21ireponame:Revista de Atenção à Saúdeinstname:Universidade Municipal de São Caetano do Sul (USCS)instacron:USCSporenghttp://seer.uscs.edu.br/index.php/revista_ciencias_saude/article/view/8817/4027http://seer.uscs.edu.br/index.php/revista_ciencias_saude/article/view/8817/4028Copyright (c) 2024 Matheus Holanda Nascimento , Tiago Miralha Costa, Ana Paula Silveira Paixão, Nilmara Suellen Lopes Castro Mendes, Lacyhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessHolanda Nascimento , MatheusMiralha Costa, TiagoSilveira Paixão, Ana PaulaSuellen Lopes Castro Mendes, NilmaraCardoso de Brito Junior, Lacy2024-01-15T12:56:33Zoai:ojs2.seer.uscs.edu.br:article/8817Revistahttps://seer.uscs.edu.br/index.php/revista_ciencias_saudePUBhttp://seer.uscs.edu.br/index.php/revista_ciencias_saude/oaieditoria.ras@online.uscs.edu.br || vera.basso@online.uscs.edu.br2359-43302359-4330opendoar:2024-01-15T12:56:33Revista de Atenção à Saúde - Universidade Municipal de São Caetano do Sul (USCS)false |
