Acute Kidney Injury IV: Diagnostic Studies and Prevention

487
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Base Excision Repair

27.8K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Area of Science:

  • Nephrology
  • Renal Medicine
  • Translational Research

Background:

  • Acute kidney injury (AKI) is a prevalent condition with significant short- and long-term adverse outcomes and high healthcare costs.
  • Despite recent advances in understanding kidney repair mechanisms, effective therapeutic strategies for AKI remain limited.
  • Translating this knowledge into clinical practice is a critical unmet need.

Purpose of the Study:

  • To review current knowledge on successful kidney repair after AKI.
  • To identify promising therapeutic targets and pathways for AKI treatment.
  • To propose a research agenda for advancing AKI therapies.

Main Methods:

  • A consensus conference convened by the Acute Dialysis Quality Initiative in April 2014.
  • Review of new evidence on successful kidney repair mechanisms.
  • Development of a framework for therapeutic targeting in AKI.

Main Results:

  • A comprehensive summary of current understanding of kidney repair post-AKI.
  • Identification of key pathways and knowledge gaps relevant to AKI treatment.
  • A proposed research agenda to accelerate clinical translation.

Conclusions:

  • Significant progress has been made in understanding kidney repair, but clinical applications are lacking.
  • A structured approach to therapeutic targeting is needed to facilitate AKI treatment development.
  • Further research is essential to bridge the gap between basic science discoveries and clinical therapies for AKI.
