AI Article Synopsis
- The study investigates the use of high-dose intravenous immunoglobulin (IVIG) as the first-line treatment for patients experiencing acute humoral rejection (AHR) after kidney transplant at the University Hospital Rijeka, Croatia.
- Eight kidney transplant recipients were evaluated, with signs of renal dysfunction and confirmed AHR through biopsies showing positive C4d-staining.
- Results showed that high-dose IVIG is effective, safe, and well tolerated in treating AHR, with varying responses observed depending on whether it was used alone or following plasmapheresis.
Article Abstract
Aim: To describe the experience of the Department of Nephrology and Dialysis, University Hospital Rijeka, Croatia, in the treatment of patients with acute humoral rejection (AHR) of kidney transplant by using high dose of intravenous immunoglobulin (IVIG) alone and as a first line treatment.
Methods: Eight kidney transplant recipients in whom the AHR appeared at different time after the transplantation were reported. At the time of transplantation cross-match in all patients was negative for both T and B cells. At the time of presentation, all patients had signs of renal allograft dysfunction and the rejection was proven by biopsy of the kidney transplant with positive C4d-staining and histopathological evidence of antibody-mediated injury. Early rejection was considered within 180 days after the transplantation and the late one 180 days after the transplantation. In two cases plasmapheresis (PAF) with albumin as replacement fluid was performed. Plasma exchange was done with a 35 mL/kg/body weight volume exchange with albumin for six times.
Results: Acute humoral rejection was classified as early in three patients and in five as late one. In two patients PAF had been performed as the first line treatment. After the completion of PAF, recuperation of severe graft dysfunction was incomplete and in addition IVIG (as a single dose of 2.0 g/kg) was administered to these patients. In six patients IVIG as a single dose of 2.0 g/kg was applied as the first line treatment.
Conclusion: Usage of high dose IVIG in the treatment of the acute humoral rejection is efficient, safe and relatively well tolerated.

Background: Patients treated with chronic dialysis or kidney transplantation have difficulties in maintaining employment. We aimed to estimate employment rates among dialysis and kidney transplant patients from 3 years before to 3 years after initiating dialysis or undergoing transplantation.
Methods: All first-time dialysis and kidney transplantation patients aged 18-65 years in Denmark from 2005 to 2019 were identified using the Danish Nephrological Register and linked with information about social security benefits.

Background: Creatinine-based estimated glomerular filtration rate (eGFR) equations are widely used in clinical practice but exhibit inherent limitations. On the other side, measuring GFR is time consuming and not available in routine clinical practice. We developed and validated machine learning models to assess the trustworthiness (i.

Chronic kidney disease (CKD) is defined by persistent abnormalities of kidney function or structure that have consequences for the health. A progressive decline of excretory kidney function has effects on body homeostasis. CKD is tightly associated with accelerated cardiovascular disease and severe infections, and with premature death.

Aims/hypothesis: Diabetic kidney disease (DKD) features intrarenal inflammation, in which T cells play a part. Hypoxia-inducible factor-1α (HIF-1α), a key transcription factor regulating cellular responses to hypoxia, is reportedly involved in the course of inflammation. The role of HIF-1α in DKD has been investigated, but the conclusions are controversial so far.
