Highlights ■ One-third of patients older than 65 years exhibit a hyperinflammatory state typical of inflammatory anemia. ■ The pathophysiology of anemia of inflammation is multifactorial. ■ Higher inflammation is associated with high prevalence of anemia and age-associated disorders. ■ The inflammatory state stimulates hepatocytes to produce hepcidin. ■ Understanding the immunomodulatory parameters in  anemia of inflammation may be effective for differential diagnosis and therapeutic approaches. ABSTRACT Objective: This study aimed to assess the relationship between hepcidin, IFN-γ, iron biomarkers, […]

Highlights ■ ACE2 rs2285666 GG genotype increased the risk ofintensive care unit risk in women. ■ TNF rs1800629 A allele was associated with severe COVID-19 and invasive mechanical ventilation. ■ IL1A rs1800587 influenced disease severity and respiratory symptoms. ■ TNF polymorphism was associated with post-COVID, cough and fatigue. ABSTRACT Objective: We evaluated the influence of single-nucleotide polymorphisms in cytokine, renin-angiotensin-aldosterone system, and uromodulin genes on COVID-19 severity and the persistence of symptoms in the post-COVID phase. Methods: Two cross-sectional cohort […]

ABSTRACT Objective: Inflammation causes the progressive destruction of the supporting tissues around teeth in patients with periodontitis. Therefore, this study aimed to investigate the immunological effects of omega-3 polyunsaturated fatty acids (n-3 PUFAs) as adjunctive therapy in patients with periodontal disease and identify potential biomarkers for the disease. Methods: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to investigate the impact of omega-3 therapy with or without acetylsalicylic acid on the immunological parameters of […]

ABSTRACT Hematopoiesis is characterized by the differentiation and maturation of multipotent stem cells into hematopoietic cells. Common lymphoid progenitor cells differentiate into B and T lymphocytes; natural killer cells can also originate from common lymphoid progenitors. In recent years, a cellular subtype of lymphocytes, called innate lymphocytes, has been described. Innate lymphoid cells (ILCs) play an important effector and regulatory role in innate immunity, and similar to natural killer cells, depend on the γc and Id2 chains for their development. […]

Highlights Higher plasma levels of CCL2 and lower plasma levels of TNF-α are associated with a greater risk of transfer to hemodialysis or mortality. Lower levels of IL-17 in the dialysate are associated with a greater risk of transfer to hemodialysis or mortality. These findings suggest that inflammatory biomarkers can be valuable tools for predicting all-cause mortality and transfer to hemodialysis in patients undergoing peritoneal dialysis. ABSTRACT Objective: This study aimed to evaluate inflammatory biomarkers in patients undergoing peritoneal dialysis […]

RESUMO Objetivo: Avaliar fatores de crescimento e citocinas em amostras de plasma rico em plaquetas obtidas por três diferentes métodos de centrifugação. Métodos: Foi coletado sangue periférico de seis indivíduos, sem doença hematológica, com idades entre 18 e 68 anos, para obtenção de plasma rico em plaquetas, utilizando o método aberto e sistemas comerciais das empresas Medtronic e Biomet. Os produtos obtidos com os diferentes tipos de centrifugação foram submetidos às análises laboratoriais, incluindo citocinas próinflamatórias e quimiocinas, por meio […]

RESUMO Objetivo: Apresentar a frequência de polimorfismo de nucleotídeo único de alguns genes da resposta imune em amostra populacional da cidade de São Paulo (SP). Métodos: Foram apresentadas as frequências de alelos de conhecidos polimorfismos de genes de imunidade inata e adquirida, a maioria com impacto funcional comprovado. Os dados foram coletados a partir de amostras de indivíduos saudáveis, irmãos não-HLA idênticos, de receptores de transplante de medula óssea do Hospital das Clínicas da Faculdade de Medicina da Universidade de […]
