Hepatitis C virus infection is associated with increased morbidity and mortality. It remains a major challenge for management and treatment, especially in patients with renal transplant. The new direct-acting antiviral agents gave big hopes to both clinicians and patients that they can overcome this challenge without major side effects. Studies recently have supported this claim; however, they are still few, limited, and may give false hopes. In the following case report, we present a case, supported by histological evidence about a possible acute rejection of kidney transplant after treatment with these new medications. This case is limited by the absence of donor-specific antibodies. This report is aimed to increase awareness about the urgent need for further studies.

Background: Intestinal transplantation (ITx) represents the only curative option for patients with irreversible intestinal failure. Nevertheless, its rejection rate surpasses that of other solid organ transplants due to the heightened immunological load of the gut. Regulatory T-cells (Tregs) are key players in the induction and maintenance of peripheral tolerance, suggesting their potential involvement in modulating host vs.

Background: Acute rejection (AR) is one of the significant factors contributing to poor prognosis in patients following kidney transplantation. Neutrophils are the main cause of early host-induced tissue injury. This paper intends to investigate the possible mechanisms of neutrophil involvement in acute rejection in renal transplantation.

Antibody-mediated rejection (ABMR) remains a leading cause of graft loss during kidney transplantation. Ischemia reperfusion injury (IRI) has been reported to promote T-cell proliferation, leading to B-cell activation and subsequent production of donor-specific antibodies (DSA), which target antigens on the vascular endothelium. We hypothesize that a novel therapeutic strategy targeting highly toxic reactive oxygen species could mitigate oxidative stress and immune responses associated with IRI.

Certain molecules, such as GLP-1 agonists and endothelin antagonists, possess nephroprotective properties. When treating IgA nephropathy, endothelin antagonists and sibeprenlimab have shown effectiveness in slowing the progression of chronic kidney isease. Additionally, the infusion of amino acids can reduce the incidence of mild acute kidney injury following cardiac surgery.
