Development of Donor-Specific Anti-HLA Antibodies After Restarting Hemodialysis Due to Graft Failure

Transplantation Proceedings
V García MontemayorP Aljama


Incidents of renal replacement therapy (RRT) from renal transplants are on the rise. Some authors have associated the development of donor-specific anti-HLA antibodies (DSA) with the end of immunosuppression treatment (IS) and/or the performing of a transplantectomy. The objective of this study was to analyze the characteristics of transplant patients having high immunological risk who restarted RRT and the subsequent development of DSA. We selected incidents on RRT carried out between 1980 and 2012 in our center: 146 cases; they presented non-DSA cytotoxic antibodies prior to returning to RRT. Survival time for the graft was 77.2 months; the average follow-up period for DSA development was 131.9 months. DSA in 76 cases (52.1%). Of 146 grafts, 72 underwent transplantectomy and 41 presented DSA after returning to RRT. In 17 of these cases (41.5%), the development of DSA occurred prior to the transplantectomy. Fifty-one cases of DSA were registered at the date of completion of the IS treatment, and 40 appeared after discontinuation (median 36 weeks) and 11 with previous appearance. IS was completed, with a median of 13 weeks after the return to RRT. No association was found between DSA development and order of graft, transplantec...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.

Super-resolution Microscopy

Super-resolution microscopy is the term commonly given to fluorescence microscopy techniques with resolutions that are not limited by the diffraction of light. Here are the latest discoveries pertaining to super-resolution microscopy.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells.

Brain Lower Grade Glioma

Low grade gliomas in the brain form from oligodendrocytes and astrocytes and are the slowest-growing glioma in adults. Discover the latest research on these brain tumors here.

CD4/CD8 Signaling

Cluster of differentiation 4 and 8 (CD8 and CD8) are glycoproteins founds on the surface of immune cells. Here is the latest research on their role in cell signaling pathways.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
