ABSTRACT
ABSTRACT

Introduction:

The immune response to different Coronavirus Disease 2019 (COVID-19) vaccines is under-investigated in end-stage kidney disease (ESKD) patients, especially in the Middle East and North Africa. We carried out this research to estimate the effectiveness of COVID-19 immunization in ESKD patients on regular hemodialysis (HD).

Methods:

In this prospective observational study, we enrolled 60 ESKD patients on regular HD who had completed COVID-19 vaccination and 30 vaccinated healthy participants. Serum levels of severe acute respiratory syndrome coronavirus 2 immunoglobulin G (SARS-COV2 IgG) were quantified 1 month after completing the vaccination schedule, and all participants were followed up from October 2021 to March 2022. The vaccines used in the study were from Pfizer-BioNTech, AstraZeneca, and Sinopharm.

Results:

The median level of SARS-COV2 IgG was lower in HD patients than in healthy participants (p < 0.001). Regarding the type of COVID-19 vaccination, there was no statistical difference in SARS-COV2 IgG levels among HD patients. During the observation period, none of the HD patients had COVID-19.

Conclusion:

COVID-19 vaccination appeared to be protective in HD patients for 6 months and the side effects of vaccines were tolerable.
RESUMO
RESUMO

Introdução:

A resposta imune a diferentes vacinas contra a doença do coronavírus 2019 (COVID-19) é pouco investigada em pacientes com doença renal em estágio terminal (DRET), especialmente no Oriente Médio e norte da África. Realizamos esta pesquisa para estimar a eficácia da imunização contra a COVID-19 em pacientes com DRET em hemodiálise regular (HD).

Métodos:

Nesse estudo observacional prospectivo, inscrevemos 60 pacientes com DRET em HD regular que haviam concluído o esquema de vacinação contra a COVID-19 e 30 participantes saudáveis vacinados. Os níveis séricos de imunoglobulina G da síndrome respiratória aguda grave do coronavírus 2 (SARS-COV2 IgG) foram quantificados um mês após a conclusão do esquema vacinal, e todos os participantes foram acompanhados de outubro de 2021 a março de 2022. As vacinas utilizadas no estudo eram da Pfizer-BioNTech, AstraZeneca e Sinopharm.

Resultados:

O nível mediano de SARS-COV2 IgG foi menor em pacientes em HD do que em participantes saudáveis (p < 0,001). Com relação ao tipo de vacinação contra a COVID-19, não houve diferença estatística nos níveis de SARS-COV2 IgG entre pacientes em HD. Durante o período de observação, nenhum dos pacientes em HD teve COVID-19.

Conclusão:

A vacinação contra a COVID-19 pareceu ser eficaz na proteção de pacientes em HD por 6 meses e os efeitos colaterais das vacinas foram toleráveis.
