Chikungunya virus (CHIKV) vertical transmission occurs due to maternal viremia in the prepartum. Clinical presentation in neonates can be varied; however, the consequences of intrauterine exposure on the immune response are unclear. Thus, we aimed to analyze inflammatory alterations in children exposed to maternal CHIKV infection.

Objectives: To analyze levels of circulant immune mediators in COVID-19 patients evolving with or without AKI.

Since distinguishing pulmonary (PTB) from latent tuberculosis (LTBI) in pediatric patients remains a challenge, we aimed to investigate the efficacy of immune mediators in diagnosing PTB and LTBI in this population. In this cross-sectional study performed with children and adolescents, serum levels of 20 biomarkers were assessed and data were analyzed according to age groups. We included 65 participants (PTB, n = 28 and LTBI, n = 37).

Objective: To study the association between ferritin levels at admission, representing an inflammatory state, and hospital mortality in COVID-19 patients.
Methods: From May through July 2020, SARS-CoV-2 positive patients with moderate to severe clinical symptoms were evaluated at admission, regarding clinical and laboratory data on renal and hepatic function, hematologic parameters, cytomegalovirus co-infection, and acute phase proteins.
