Introduction: Elucidating the molecules involved in the inflammatory process of chronic Chagas disease may allow identification of treatment targets.

Methods: The ex vivo phenotypic expression of chemokine receptors CCR1, CCR3, CCR4, CCR5, CXCR2, CXCR3, CXCR4, and CXCR5 on the CD4+ and CD8+ T-cells of patients with chronic Chagas cardiomyopathy of varying severity was evaluated using flow cytometry.

Results: Differential expression of CD4+CCR3+ and CD8+CCR4+ T-cells was observed in patients with mild cardiac involvement compared, respectively, with patients with severe cardiac and asymptomatic forms of Chagas disease.

Conclusions: These receptors are possibly involved in the pathogenesis of chronic Chagas cardiomyopathy.

Despite being the most relevant and critical option for managing Chagas disease, pharmacological therapy is currently limited by the availability of only two drugs, benznidazole and nifurtimox. Their effectiveness is further restricted in the chronic phase of the infection, as they induce severe side effects and require prolonged treatment. Additionally, the use of these drugs can lead to the emergence of substantial resistance problems, compounded by the potential natural resistance of some parasite isolates.

Chagas disease is a neglected tropical disease caused by Trypanosoma cruzi with clinical presentations ranging from asymptomatic to cardiac and/or gastrointestinal complications. The mechanisms of pathogenesis are still poorly understood, but T. cruzi strain diversity may be associated with disease progression.

Chronic chagasic cardiomyopathy is the most severe clinical manifestation of Chagas disease, which affects approximately seven million people worldwide. Latin American countries bear the highest burden, with the greatest morbidity and mortality rates. Currently, diagnostic methods do not provide information on the risk of progression to severe stages of the disease.

Renal osteodystrophy (ROD) represents histological bone changes in patients with chronic kidney disease and is classified according to turnover and mineralization. This cross-sectional study evaluates several bone biomarkers and their ability to discriminate turnover and mineralization defects in hemodialysis (HD) patients. Bone-specific [BSAP] and total [tAP] alkaline phosphatase, procollagen-1 N-terminal propeptide [P1NP], C-terminal cross-linking telopeptide [CTX], intact [iPTH] and whole [wPTH] parathyroid hormone, sclerostin [SOST], fibroblast growth factor 23 [FGF-23], vitamin D, osteoprotegerin [OPG], and receptor activator of nuclear factor κB ligand [RANKL] were collected before the bone biopsy.
