Insights

Atrial fibrillation (AF) and chronic kidney disease (CKD) often coexist. This review examines non-vitamin K antagonist oral anticoagulants (NOACs) for stroke prevention in CKD patients, focusing on those with severe or end-stage renal disease.

Area of Science:

  • Nephrology
  • Cardiology
  • Pharmacology

Background:

  • Atrial fibrillation (AF) and chronic kidney disease (CKD) are prevalent, particularly in aging populations with comorbidities.
  • A bidirectional relationship exists between AF and CKD, with each condition potentially worsening the other.
  • CKD patients with AF face elevated risks of stroke, mortality, cardiac events, and bleeding.

Purpose of the Study:

  • To review the evidence for non-vitamin K antagonist oral anticoagulants (NOACs) in patients with chronic kidney disease (CKD).
  • To summarize current knowledge on the efficacy and safety of NOACs for preventing AF-related stroke and systemic embolism in severe and end-stage renal disease.

Main Methods:

  • Literature review of studies investigating NOACs in patients with varying degrees of renal dysfunction.
  • Analysis of data on stroke prevention, systemic embolism, and bleeding events associated with NOAC use in CKD.

Main Results:

  • NOACs demonstrate efficacy in mild-to-moderate renal dysfunction.
  • Limited data currently exists on NOAC use in severe and end-stage renal disease.
  • Further research is needed to establish optimal NOAC use in advanced CKD stages.

Conclusions:

  • Stroke prevention in AF patients with CKD is crucial.
  • The role of NOACs in severe and end-stage renal disease requires further investigation.
  • Evidence-based guidelines are needed for NOAC prescription in advanced CKD.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
