Abstract
Introdução: A tuberculose, provocada pelo Mycobacterium tuberculosis, permanece entre as infeções mais letais do mundo, com 1,25 milhões de mortes em 2023, segundo a Organização Mundial de Saúde. Embora seja amplamente reconhecida pelos efeitos respiratórios, a doença causa alterações hematológicas significativas. Objetivo: Esta revisão sistemática procurou averiguar as alterações do perfil hematológico de doentes com tuberculose, nas fases pré e pós tratamento. Métodos: Realizou-se uma pesquisa sistemática da literatura, a partir de bases de dados científicos como PubMed-MEDLINE, ScienceDirect e b-on, seguindo as diretrizes da metodologia prisma 2020 e os critérios de elegibilidade PICOS. Resultados: Foram incluídos cinco estudos, que revelaram alterações frequentes como anemia, leucocitose e trombocitose na fase inicial da doença. Após o tratamento, alguns parâmetros normalizaram, mas verificaram-se quadros como anemia, neutropenia e trombocitopenia.
Discussão: A tuberculose causa alterações hematológicas significativas, antes do tratamento, devido à resposta imunológica e devido à processos infeciosos. Após a terapia, muitos dos parâmetros normalizam, embora alguns persistem, sugerindo possíveis efeitos colaterais das terapias antituberculose.
Conclusão: As alterações hematológicas são frequentes em pacientes com tuberculose e variam ao longo do tratamento. A monitorização contínua dos parâmetros laboratoriais é essencial para avaliar a resposta terapêutica e prevenir possíveis complicações.
Abstract: Introduction: Tuberculosis, caused by Mycobacterium tuberculosis, remains one of the most lethal infections worldwide, with 1.25 million deaths in 2023, according to the World Health Organization. Although it is widely recognized for its respiratory effects, the disease also leads to significant hematological alterations. Objective: This systematic review aimed to investigate the changes in hematological profiles of patients with tuberculosis during pre- and post-treatment phases. Methods: A systematic literature search was conducted using scientific databases such as PubMed-MEDLINE, ScienceDirect and b-on, following the PRISMA 2020 guidelines and the PICOS eligibility criteria. Results: Five studies were included, revealing common alterations such as anemia, leukocytosis, and thrombocytosis in the initial phase of the disease. After treatment, some parameters normalized, but conditions like anemia, neutropenia, and thrombocytopenia were observed. Discussion: Tuberculosis causes significant hematological changes before treatment, due to the immune response and infectious processes. After therapy, many parameters normalize, although some persist, suggesting possible side effects of anti-tuberculosis therapies. Conclusion: Hematological alterations are frequent in patients with tuberculosis and vary throughout treatment. Continuous monitoring of laboratory parameters is essential to assess therapeutic response and prevent possible complications.
