Abstract
- Introduction: Studies have shown that the renin angiotensin aldosterone system (RAAS) and inflammation are related to kidney injury progression. The aim of this study was to evaluate RAAS molecules and chemokine (C-C motif) ligand 2 (CCL2) in 82 patients with chronic kidney disease (CKD). Methods: Patients were divided into two groups: patients diagnosed with CKD and patients without a CKD diagnosis. Glomerular filtration rate (GFR) and albumin/creatinine ratio (ACR) were determined, as well as plasma levels of angiotensin-(1-7) [Ang-(1-7)], angiotensin-converting enzyme (ACE)1, ACE2, and plasma and urinary levels of CCL2. Results: CCL2 plasma levels were significantly higher in patients with CKD compared to the control group. Patients with lower GFR had higher plasma levels of ACE2 and CCL2 and lower ratio ACE1/ACE2. Patients with higher ACR values had higher ACE1 plasma levels. Conclusion: Patients with CKD showed greater activity of both RAAS axes, the classic and alternative, and higher plasma levels of CCL2. Therefore, plasma levels of RAAS molecules and CCL2 seem to be promising prognostic markers and even therapeutic targets for CKD. Resumo Introdução: Estudos têm mostrado que o sistema renina angiotensina aldosterona (SRAA) e a inflamação estão relacionados à progressão da lesão renal. O objetivo deste estudo foi avaliar moléculas do SRAA e o Ligante 2 de Quimiocina com Motivo C-C (CCL2) em 82 pacientes com doença renal crônica (DRC). Métodos: Os pacientes foram divididos em dois grupos: pacientes diagnosticados com DRC e pacientes sem diagnóstico de DRC. Foram determinadas a taxa de filtração glomerular (TFG) e a relação albumina/creatinina (RAC), assim como os níveis plasmáticos de angiotensina-(1-7) [Ang-(1-7)], enzima conversora de angiotensina (ECA)1, ECA2 e níveis plasmáticos e urinários de CCL2. Resultados: Os níveis plasmáticos de CCL2 foram significativamente mais altos em pacientes com DRC em comparação com o grupo controle. Pacientes com TFG mais baixa apresentaram níveis plasmáticos mais elevados de ECA2 e CCL2 e menor relação ECA1/ECA2. Pacientes com valores de RAC mais altos apresentaram níveis plasmáticos de ECA1 mais elevados. Conclusão: Pacientes com DRC mostraram maior atividade de ambos os eixos do SRAA, o clássico e o alternativo, e níveis plasmáticos mais altos de CCL2. Portanto, os níveis plasmáticos de moléculas do SRAA e CCL2 parecem ser marcadores prognósticos promissores e até mesmo alvos terapêuticos para a DRC.
